DESCRIPTION

of the Italian Patent for Industrial Invention entitled:

?SLAB TRANSPORT AND/OR LAYING DEVICE?

TECHNICAL FIELD

The present invention relates to a device for transporting and/or placing slabs (or slab-like elements), for example of large format, such as ceramic or glass or marble or similar metal slabs.

Pi? in particular, the invention relates to a manually operable device for transporting and/or placing slabs for gripping, transporting and/or placing slabs by at least one operator (for example even just one operator).

PRE-EXISTING TECHNIQUE

As ? It is well known that the use of large format slabs (for example ceramics) has recently become more widespread on the market, such as tiles in the format 1-1.5 x 3-3.5 meters and reduced thickness.

Such slabs are generally packaged stacked in crates having rigid sidewalls surrounding the stack of slabs or on racks.

To be able to take a slab of summit? from the stack and proceed with the operations of positioning and laying the same are known suction cup gripping devices, which have one or more? rigid bars equipped with a series of suction cups suitable for adhering to an upper surface of the slab (for example the visible surface of the tiles). The operators, for example two in number, by means of handles connected to the rigid bar lift or pick up the slab held by the suckers and place it, for example, in correspondence with the laying area.

A need felt in these suction cup gripping devices? that of facilitating, for the operator, the transport operations of the slab and, for example, facilitating or allowing the operations of laying (and releasing) the slab itself in the corresponding laying area, for example directly on the adhesive placed in the laying area . Furthermore, a need felt in the sector ? that of making the transport and/or placing operations of the slab picked up with such suction cup gripping devices possible and simple, even by a single operator, when the size and weight of the slab allow it.

An object of the present invention ? that of satisfying these and other requirements of the prior art, in the context of a simple, rational and low-cost solution.

These purposes are achieved by the characteristics of the invention set forth in the independent claims. The dependent claims outline preferred and/or particularly advantageous aspects of the invention.

EXHIBITION OF THE INVENTION

The invention, in particular, provides a device for transporting and/or laying slabs which comprises:

- a suction cup gripping device configured to releasably hold a plate and provided with at least one handle;

- a support trolley equipped with a support frame and at least one wheel resting on the ground, in which the support frame is ? associated with the gripping device on the opposite side of the handle.

Thanks to this solution, ? possible to obtain a convenient device for the transport and installation of even large-sized slabs, for example allowing transport and/or installation even by a single operator (compatibly with the weight of the slab), but at the same time allowing transport and pose in pi? of a person and maintaining the functionality? of the known gripping devices.

In particular, thanks to this solution ? Is it possible to configure and operate a suction gripping device as a lever of the second kind for lifting and transporting a slab suspended below (i.e. a suspended load) in grip with the suction cups, for example allowing to facilitate the maneuverability? (even for a single person), in a similar way to using a wheelbarrow for a lean load.

Preferably, the support wheel can? be a pivoting wheel about a pivot axis.

Thanks to this solution, the device can? be easily governed and steered along permitted (free) transport trajectories, for example even in narrow maneuvering spaces.

According to a preferred embodiment, the support carriage, i.e. its support frame, can be rotatably associated with the gripping device about an axis of rotation parallel to a gripping plane defined by at least one suction cup of the suction cup gripping device.

Thanks to this solution, the rotation axis defines a particularly comfortable and effective lava lifting fulcrum of the second kind and, moreover, the pivot axis of the pivoting support wheels (where provided) remains in a vertical position regardless of the movement. inclination of the gripping surface of the gripping device, allowing a high maneuverability? of the device in each operating configuration. Advantageously, the support frame can include a hinge pin and the gripping device can? comprising a hinge seat adapted to receive the hinge pin in a resolvable manner.

Thanks to this solution, the gripping device is not burdened with additional weights (for when it must be used separately from the support trolley) and the reciprocal connection ? simple, intuitive and facilitated.

According to an alternative embodiment, the support carriage, or its support frame, can be rigidly fixed to the gripping device, a pivot axis of the pivot wheel being inclined (not parallel), for example in a fixed manner, to a gripping plane defined by at least one suction cup of the suction cup gripping device.

Thanks to this solution, ? It is possible to obtain the effects of overturning, lifting and transporting the slab with the gripping device by means of a simple and intuitive construction.

According to a further aspect of the invention, the support wheel can be associated in an adjustable way to the support trolley, or to at least a part of the support frame (preferably with respect to the rotation pin of the same), along a sliding direction parallel to a gripping plane defined by at least one suction cup of the gripping device sucker (ie parallel to the rotation pin itself).

Thanks to this solution, pu? the position of the support wheel may be varied according to the weight and/or size of the slab gripped by the gripping device.

According to a further aspect of the invention, the device can comprising a braking assembly, configured to brake, at least partially, the rolling of the support wheel.

Thanks to this solution, the lifting and lowering operations of the slab and/or of the gripping device (with the support carriage resting on the ground by means of the support wheel) can be facilitated, preventing undesired slipping or sliding of the support carriage.

According to an advantageous aspect, the braking unit can? comprising at least one foot associated with the suction cup gripping device and configured to rest on the ground in at least one determined reciprocal position between the support carriage, or its support frame, and the gripping device.

Preferably, the gripping device can be equipped with a further handle opposite and aligned with said handle, the support frame of the support trolley being able to be associated in proximity or in correspondence with the further handle (or the handle which supports it) of the gripping device.

Thanks to this solution, ? made it possible to selectively use the gripping device in a traditional way (with the use of two people on opposite sides) or in an innovative way (with the use of a single person positioned at the handle/s opposite the/ and support wheel/s.

According to an advantageous aspect, the support carriage can? be removably associated with the gripping device.

For the same purposes set out above, the present invention also makes available a support carriage for suction cup gripping devices for slabs, in which the support carriage is? equipped with a support frame and at least one support wheel on the ground, in which the support wheel is a pivoting wheel with a pivoting axis that can be tilted or inclined with respect to a gripping plane defined by at least one suction cup of the suction cup gripping device.

This support trolley (individually or together with the handles to which it is intended to be associated) can? be associated with any commercially available suction cup device to increase its potential? of transport and installation described above.

BEST WAY TO CARRY OUT THE INVENTION

With particular reference to these figures, yes? globally indicated with 1 a slab transport and/or installation device (i.e. for the transport and/or installation of one slab at a time), generally indicated with the letter L.

By plates L we mean a plate-like element, such as a ceramic plate, a glass plate, a natural stone plate, such as marble, granite or the like, a metal plate or other, preferably large format, for example which have dimensions substantially between 3-3.5 meters x 1-1.5 meters.

As known, each slab L has an upper surface (in view) and a lower surface (for installation).

Gripping device

The transport and/or laying device 1 comprises, for example, a suction cup gripping device 10, which ? fully illustrated in Figures 1-18.

The gripping device 10 is, for example, configured to hold a slab L in a releasable manner, preferably operating on the upper surface (in view) of the slab L, for example by means of the suction cup effect (i.e. by operating a depression suitable for retaining the sheet weight L).

The gripping device 10 comprises at least one longitudinal bar 20 which has a longitudinal axis A.

The longitudinal bar 20 ? for example, adjustable in length, how better will it be? described below.

The longitudinal bar 20 comprises (or consists of) a first longitudinal member 21 having a respective longitudinal axis and a second longitudinal member 22 having a relative longitudinal axis parallel to the longitudinal axis of the first longitudinal member 21.

The longitudinal axes of the first longitudinal member 21 and of the second longitudinal member 22 overall define the longitudinal axis A of the longitudinal bar 20.

The first longitudinal member 21 and the second longitudinal member 22 are placed side by side with respect to a side by side direction B orthogonal to their longitudinal axis (and parallel to the plane of arrangement of the slab L ? or of its visible surface ? in use).

It is not excluded that the first longitudinal member 21 and the second longitudinal member 22 can be inserted one inside the other to define a connection of the telescopic type. The first longitudinal member 21 and/or the second longitudinal member 22 are defined by longitudinal sections for example substantially rigid (not deformable in bending or torsion under the workloads of use of the gripping device 10).

It is not excluded that the longitudinal bar 20 may comprise more? of two side members coupled together.

The first longitudinal member 21 has a substantially quadrangular section, for example rectangular, constant along the entire length.

Preferably, therefore, the first longitudinal member 21 has a pair of side walls (substantially parallel to each other), for example orthogonal in use to the visible surface of the plate L being gripped, and a pair of base walls (substantially parallel to each other) in square and adjacent to the side walls, which are in use parallel to the visible surface of the plate L being gripped.

For example, the first spar 21 ? obtained by extrusion of a metallic material, for example a light alloy (such as aluminum for example), and preferably ? internally hollow (that is, it has a full length axial cavity although it can be equipped with various full length reinforcing partitions).

The first longitudinal member 21 has, in correspondence with a first side wall thereof, a hollow 210, for example with a substantially dovetail or "T" shaped cross-section, with its entire longitudinal extension.

Quarry 210 ? defined in correspondence with a first larger side wall of the first side member 21.

A second side wall opposite the first side wall presenting the groove 210, for example, comprises longitudinal knurling, for example along its entire longitudinal development, or could have shaped profiles along its entire longitudinal development or a groove along its entire longitudinal development or be substantially smooth and/ or planar.

Furthermore, the first longitudinal member 21 has, in correspondence with a first base wall of the same, for example upper (or - in use - distal from the visible surface of the plate L being gripped), a further hollow 211, for example with a cross section substantially dovetail or ?T? shaped, with full lengthwise development.

In detail, the further quarry 211 ? defined in correspondence with a first base wall smaller than the first side member 21.

A second base wall opposite the first base wall presenting the further groove 211, for example, comprises longitudinal knurls, for example along the entire longitudinal development, or could have shaped profiles along the entire longitudinal development or a groove along the entire longitudinal development or be substantially smooth and/or planar (as shown in the example).

The first longitudinal member 21, for example, comprises one or two caps each able to close one end? of the first spar 21, or of the cavity? axial of the same.

The first spar 21 has an extremity? external, which defines a portion of the end? of the longitudinal bar 20 as a whole, and an opposite end? internal.

The first longitudinal member 21 comprises a first retaining body 215 able to protrude laterally from the first longitudinal member itself on the opposite side with respect to the first lateral wall presenting the slot 210.

The First Retention Corps 215 ? arranged at (or near?) the (only) extremity? inside of the first spar 21.

In practice, the first retaining body 215 extends beyond the second lateral wall, opposite the first lateral wall presenting the groove 210.

The first retaining body 215 of the first spar 21? configured to embrace (slidingly) at least partially an axial portion of the second longitudinal member 22, as will be better? illustrated below.

Preferably, the first holding body 215 has a first bracket (lower, i.e. proximal to the gripping plate L) and a second bracket (upper, i.e. distal to the gripping plate L) parallel to each other and each protruding laterally from the first longitudinal member 21 from the opposite side with respect to the first lateral wall presenting the groove 210.

The distance between the first shelf and the second shelf? at least equal to (or slightly greater than) the height of the first side member 21 (or rather the distance between the base walls of the same).

The first shelf has one end? free (distal from the second lateral wall, opposite the first lateral wall presenting the recess 210) folded towards the second shelf (and, preferably, at a distance from it, although it is not excluded that it may join the second shelf), which ? for example substantially parallel to the second lateral wall of the first longitudinal member 21 (and is located at a distance from the second lateral face of the first longitudinal member 21 at least equal to or slightly greater than the transversal width of each base wall of the first longitudinal member 21 itself).

In practice, the first bracket has an internal face in contact with the second lower base wall of the first longitudinal member 21 and which protrudes laterally from it, projecting transversely in a direction parallel to said base wall; the inner face of the first bracket effectively defines a lower support surface for an axial portion of the second longitudinal member 22.

The extremity? folded free of the first bracket ?, on the other hand, configured to embrace laterally the axial portion of the second longitudinal member 22.

The second bracket has an internal face in contact with the first upper base wall of the first longitudinal member 21 and which protrudes laterally from it, projecting transversely in a direction parallel to this base wall and defining an upper support surface for an axial portion of the second longitudinal member 22 (parallel and at least partially facing the lower support plane defined by the first bracket).

The first bracket and the second bracket are, in the example, joined together by a joining wall, substantially at right angles with them, which laterally wraps the first longitudinal member 21, i.e. its first lateral wall equipped with the slot 210.

The first retention body 215 has a decidedly limited axial length, i.e. it has an axial length substantially equal to the width of the longitudinal bar 20 in the side-by-side direction of the first longitudinal member 21 with respect to the second longitudinal member 22, i.e. the axial length of the first retention body 215 does not exceed twice the said width of the longitudinal bar 20.

The first retaining body 215 has a (much) smaller length than the length of the first longitudinal member 21 and/or the second longitudinal member 22, for example equal to 5 / 100 of the length of the first longitudinal member 21 and/or the second longitudinal member 22.

The First Retention Corps 215 ? fixed, for example in a removable manner, to the first longitudinal member 21, for example by means of threaded members.

In the example, the first holding body 215 ? fixed to the first side member 21 through the further slot 211 present in the upper base wall of the first side member 21 itself, for example by one or two tightening screws equipped with nuts which engage said further slot 211.

Again, a first sliding shoe 216 can? be fixed to the first holding body 215, for example to the second shelf of the same, even more? in detail to the internal face of the same which protrudes transversally beyond the first longitudinal member 21 (ie which faces the second bracket).

In practice, the first sliding block 216 ? adapted to be interposed between the first retaining body 215, for example the second bracket thereof, and the axial portion of the second longitudinal member 22 embraced by the first retaining body 215.

The first sliding block 216 ? for example fixed to the first retaining body 215 by interposition (in a vice) between the first bracket and the upper base wall of the first longitudinal member 21, being able in any case to protrude (substantially the same as the second bracket) from said upper base wall of the first longitudinal member 21 .

The first sliding block 216 ? made of a material with a reduced coefficient of sliding friction, i.e. having a coefficient of sliding friction lower than the material with which it is made? made the first retaining body 215 and/or the first longitudinal member 21 and/or the second longitudinal member 22.

For example, the first sliding block 216 ? made or coated with Teflon. The second longitudinal member 22 has a substantially quadrangular section, for example rectangular, which is constant along the entire length.

Preferably, therefore, the second longitudinal member 22 has a pair of side walls (substantially parallel to each other), for example orthogonal in use to the visible surface of the plate L being gripped, and a pair of base walls (substantially parallel to each other) in square and adjacent to the side walls, which are in use parallel to the visible surface of the plate L being gripped.

For example, the second spar 22 ? obtained by extrusion of a metallic material, for example a light alloy (such as aluminum for example), and preferably ? internally hollow (that is, it has a full length axial cavity although it can be equipped with various full length reinforcing partitions).

The second longitudinal member 22 has, in correspondence with a first side wall thereof, a hollow 220, for example with a substantially dovetail or ?T? shaped cross section, with its entire longitudinal development.

Quarry 220 ? defined in correspondence with a first side wall larger than the second longitudinal member 22.

A second lateral wall opposite the first lateral wall presenting the groove 220, for example, comprises longitudinal knurling, for example with its entire longitudinal development, or it could have shaped profiles along its entire longitudinal development or a groove along its entire longitudinal development or be substantially smooth and/ or planar.

Furthermore, the second longitudinal member 22 has, in correspondence with a first base wall of the same, for example upper (or - in use - distal from the visible surface of the plate L being gripped), a further hollow 221, for example with a cross section substantially dovetail or ?T? shaped, with full lengthwise development.

The further quarry 221 ? defined in correspondence with a first base wall smaller than the second side member 22.

A second base wall opposite the first base wall presenting the further groove 221, for example, comprises longitudinal knurls, for example along the entire longitudinal development, or could have shaped profiles along the entire longitudinal development or a groove along the entire longitudinal development or be substantially smooth and/or planar (as shown in the example).

The second longitudinal member 22, for example, comprises one or two caps each capable of closing one end? of the second spar 22, or of the cavity? axial of the same.

The second spar 22 has an extremity? external, which defines a portion of the end? of the longitudinal bar 20 as a whole (opposite to the end portion defined by the external end of the first longitudinal member 21), and an opposite end? internal.

The second longitudinal member 22 comprises a second retention body 225 able to protrude laterally from the second longitudinal member itself on the opposite side with respect to the first lateral wall presenting the slot 220.

The second detention corps 225 ? arranged at (or near?) the (only) extremity? inside of the second side member 22.

In practice, the second retention body 225 extends beyond the second lateral wall, opposite the first lateral wall presenting the groove 220.

The second retaining body 225 of the second longitudinal member 22? configured to embrace (slidingly) at least partially an axial portion of the first longitudinal member 21, as will be better? illustrated below.

Preferably, the second holding body 225 has a first bracket (lower, i.e. proximal to the gripping plate L) and a second bracket (upper, i.e. distal to the gripping plate L) parallel to each other and each protruding laterally from the second longitudinal member 22 from the opposite side with respect to the first lateral wall presenting the groove 220.

The distance between the first shelf and the second shelf? at least equal to (or slightly greater than) the height of the second longitudinal member 22 (ie the distance between the base side walls of the same).

The first shelf has one end? free (distal from the second lateral wall, opposite the first lateral wall presenting the recess 220) folded towards the second shelf (and, preferably, at a distance from it, although it is not excluded that it may join the second shelf), which ? for example substantially parallel to the second lateral wall of the second longitudinal member 22 (and is located at a distance from the second lateral face of the second longitudinal member 22 at least equal to or slightly greater than the transversal width of each base wall of the second longitudinal member 22 itself).

In practice, the first bracket has an internal face in contact with the lower base wall of the second longitudinal member 22 and which protrudes laterally from it, projecting transversely in a direction parallel to said base wall, defining a lower support surface for a portion axial of the first side member 21.

The extremity? folded free of the first bracket ?, on the other hand, configured to embrace laterally the axial portion of the first longitudinal member 21.

The second bracket has an internal face in contact with the upper base wall of the second longitudinal member 22 and which protrudes laterally from it, projecting transversely in a direction parallel to this base wall and defining an upper support surface for an axial portion of the first side member 21 (parallel and at least partially facing the lower support surface defined by the first bracket).

The first bracket and the second bracket are, in the example, joined together by a joining wall, substantially at right angles with them, which laterally wraps the second longitudinal member 22, i.e. its first side wall equipped with the slot 220.

The second retention body 225 has a decidedly limited axial length, i.e. it has an axial length substantially equal to the width of the longitudinal bar 20 in the side by side direction of the first longitudinal member 21 with respect to the second longitudinal member 22, i.e. the axial length of the second retention body 225 does not exceed twice the said width of the longitudinal bar 20.

The second holding body 225 has a (much) shorter length than the length of the second longitudinal member 22 and/or the first longitudinal member 21, for example equal to 5 / 100 of the length of the first longitudinal member 21 and/or the second longitudinal member 22.

The second detention corps 225 ? fixed, for example in a removable manner, to the second longitudinal member 22, for example by means of threaded members.

In the example, the second holding body 225 ? fixed to the second side member 22 through the further slot 221 present in the upper base wall of the second side member 22 itself, for example by one or two tightening screws equipped with nuts which engage said further slot 221.

Again, a second sliding shoe 226 can be fixed to the second holding body 225, for example to the second shelf of the same, even more? in detail to the internal face of the same which protrudes transversely beyond the second longitudinal member 22 (ie which faces the second bracket).

In practice, the second sliding block 226 ? adapted to be interposed between the second retaining body 225, for example the second bracket thereof, and the axial portion of the first longitudinal member 21 embraced by the second retaining body 225.

The second sliding block 226 ? for example fixed to the first retaining body 225 by interposition (in a vice) between the first bracket and the upper base wall of the second longitudinal member 22, being able in any case to protrude (substantially the same as the second bracket) from said upper base wall of the second longitudinal member 22 .

The second sliding block 226 ? made of a material with a reduced coefficient of sliding friction, i.e. having a coefficient of sliding friction lower than the material with which it is made? made the second retaining body 225 and/or the first longitudinal member 21 and/or the second longitudinal member 22.

For example, the second sliding block 226 ? made or coated with Teflon. The first retention body 215 and the second retention body 225 are, in practice, equal to each other (and/or symmetrically arranged).

The first longitudinal member 21 and the second longitudinal member 22 have for example the same shape and size of the cross section.

The first longitudinal member 21 and the second longitudinal member 22 have, for example, the same length.

The first longitudinal member 21 and the second longitudinal member 22 are for example completely similar (identical) in shape and size.

The first longitudinal member 21 and the second longitudinal member 22 are side by side (with respect to the side by side direction B) so that the second side walls opposite the first side walls having the slots 210, 220 are substantially in contact with each other (by axial sliding) or little spaced.

The slots 210,220 are therefore mutually opposite (ie open in opposite directions).

In practice, the first longitudinal member 21 and the second longitudinal member 22 slide one over the other without interconnecting elements.

It is not excluded that a connection of the prismatic and/or sliding guide type is defined between the first longitudinal member 21 and the second longitudinal member 22.

In practice, the first longitudinal member 21 and the second longitudinal member 22 are mutually symmetrical with respect to a plane of symmetry orthogonal to the juxtaposition direction B (that is, orthogonal to the visible surface of the gripping plate L).

In a preferred embodiment, the longitudinal bar 20 also comprises a guide tube 23 able to mutually constrain the first longitudinal member 21 and the second longitudinal member 22, allowing/assisting a reciprocal longitudinal translation, i.e. along the longitudinal axis A of the longitudinal bar 20 .

The guide tube 23 can? be of the type with cross section open, closed, made of one piece or in two or more? pieces depending on the construction needs, how better will it be? detailed below.

The guide sleeve 23 comprises a tubular body provided with a cavity through axial having a longitudinal axis substantially parallel (and coinciding) with the longitudinal axis A of the longitudinal bar 20 as a whole. For example, the cavity axial (and/or the tubular body) has a substantially prismatic shape, for example with a quadrangular cross-section, for example substantially square or rectangular.

The cavity? axial has a cross section, constant throughout its development, configured for (i.e. having a shape and a size such as) to be inserted, substantially to size, (simultaneously) by both the first longitudinal member 21 and the second longitudinal member 22 side by side as described above, or an intermediate section of the same interposed between the? extremity? internal and the? extremity? external to them.

The axial length of the guide sleeve 23 ? decidedly contained, or the axial length? substantially equal to the width of the longitudinal bar 20 in the side-by-side direction of the first longitudinal member 21 with respect to the second longitudinal member 22, i.e. the axial length of the guide sleeve 23 does not exceed double the said width of the longitudinal bar 20.

The cavity? and, therefore, the tubular body of the guide tube 23 has a (much) shorter length than the length of the first longitudinal member 21 and/or the second longitudinal member 22, for example equal to 5 / 100 of the length of the first longitudinal member 21 and /o of the second side member 22.

Furthermore, the weight of the guide tube 23 ? a lot of content, for example ? substantially equal to or less than the weight of the longitudinal bar 20, preferably less than the weight of one of the first longitudinal member 21 and/or the second longitudinal member 22.

The tubular body of the guide tube 23 ? for example a substantially rigid body (not deformable in longitudinal bending or torsion under the workloads of proper use of the gripping device 10).

Are the first longitudinal member 21 and the second longitudinal member 22 both (simultaneously) inserted axially inside the cavity? axial of the guide tube 23 with the possibility? to flow in relative sliding along the longitudinal direction given by the longitudinal axis of the cavity? axial for adjusting the length of the longitudinal bar 20.

For example, between the guide tube 23 and each of the first longitudinal member 21 and the second longitudinal member 22 ? defined as a prismatic type mechanical connection. In practice, the first spar 21 ? stuck in the cavity? axial of the guide sleeve 23 so as to present both ends? protruding axially from the ends? axial of the guide tube 23, likewise the second longitudinal member 22 ? stuck in the cavity? axial of the guide sleeve 23 so as to present both ends? protruding axially from the ends? of the guide tube 23. Each of the first longitudinal member 21 and the second longitudinal member 22 ? individually slidable axially along the longitudinal axis of the guide tube 23 inside the respective portion of cavity? of the guide sleeve 23 for adjusting the overall length of the longitudinal bar 20.

For example each of the first longitudinal member 21 and the second longitudinal member 22 ? sliding between two opposing end working positions and in infinite intermediate positions between them, in which they both remain filled in the guide tube 23 and in which, for example, in a first end position the end? internal (ie the respective body of retention 215,225) is located in the vicinity? or correspondence of an extremity? of the guide sleeve 23 and in a second extremal position, the extremity? outside is located near? or at the opposite end? of the guide sleeve 23.

For example, the first retaining body 215 defines a mechanical limit stop (mating with the guide tube 23) for the axial sliding of the first longitudinal member 21 in its first extreme position and the second retaining body 225 defines a mechanical limit stop ( abutting with the guide tube 23) for the axial sliding of the second longitudinal member 22 in its first extreme position.

It is not excluded that one or both of the longitudinal members 21, 22 can be withdrawn from the guide tube 23 if necessary.

The longitudinal bar 20, in particular, has a variable length (and adjustable at will) between a configuration of maximum elongation, in which its length is ? maximum, and a configuration of minimum elongation, in which its length ? minimal.

In the maximum elongation configuration both the first longitudinal member 21 and the second longitudinal member 22 are in a first extreme position, in which each end? internal is located near? or correspondence of an extremity? of the guide tube 23 and both are in any case inserted into the guide tube 23. In the minimum elongation configuration both the first longitudinal member 21 and the second longitudinal member 22 are in an axially intermediate position between the first extreme position and the second extreme position, in which, for example, each end? external ? substantially equidistant from the respective end? internal (or in any case the first longitudinal member 21 and the second longitudinal member 22 are placed side by side/overlapping each other for most of their axial length). The guide tube 23 can? be made in a single body or by the union of two or more? separable bodies, how better will it be? detailed below.

The guide tube 23 comprises a blocking unit for the temporary and solvable blocking of the relative longitudinal sliding of the first side member 21 and/or of the second side member 22 along the longitudinal axis of the guide tube 23 itself.

For example, the passage light of the cavity? guide shaft axial 23 ? variable and operable between an enlarged configuration, in which it allows the reciprocal sliding of the first longitudinal member 21 and the guide sleeve 23 and/or of the second longitudinal member 22 and the guide sleeve 23, and a restricted configuration, in which it prevents or opposes the sliding reciprocal of the first longitudinal member 21 and the guide sleeve 23 and/or of the second longitudinal member 22 and the guide sleeve 23.

The locking group? for example rigidly connected to the guide tube 23.

The locking group? for example a clamping unit of the clamp type, i.e. capable of clamping the guide sleeve 23, i.e. its tubular body, reciprocally in a clamp (in a transverse direction with respect to the longitudinal axis A of the longitudinal bar 20), with one or both spars 21,22.

The locking unit and the guide sleeve 23 can? present various embodiments.

In the illustrated example, the guide sleeve 23, ie the tubular body, is made from the union of two coupled bodies.

For example, the guide tube 23 comprises a first shell, for example comprising a ?C?-shaped open cross section, and a second shell, for example substantially plate-shaped, able to close the open section of the first shell.

The first shell and the second shell have respective lugs suitable for facing each other for fastening, by means of clamping members 25, for example threaded, of the first shell to the second shell.

In the example, the first shell and the second shell each have an ear at each end? of contact between the shells.

For example, each lug of the first shell has at least one through hole adapted to be aligned with its through axis to a through hole made in the respective lug of the second shell.

The through holes are threaded by a clamping member 25.

In this first embodiment, the clamping member 25 comprises a threaded pin inserted in the through holes, locked axially, for example by means of a nut or by screwing, to one of the through holes, and equipped with an actuation member, for example a prismatic head and/or a cam lever associated with one end? of the threaded pin distal from the through hole to which ? the threaded pin blocked.

One of the two ears of each shell ? constrained by clamping members 25 having a prismatic head (for example the lower ears), while the other of the ears of each shell ? constrained by clamping members 25 having a cam lever.

The clamping member 25 ? operable (manually) for the release and reciprocal tightening of the first shell and the second shell, so as to bring the cavity? of the guide tube 23 respectively in its enlarged configuration, in which it allows the axial sliding of the first longitudinal member 21 and of the second longitudinal member 22 inside it, and in its narrower position, in which it prevents (by friction) or opposes the sliding of the first spar 21 and the second spar 22 inside it.

In this configuration, the locking group ? therefore defined by the tubular body itself, which acts as a vice, the jaws of which are the first shell and the second shell.

In general, the tubular body of the guide sleeve 23 can include holes or lightening gaps.

The gripping device 10 comprises at least one suction cup gripping member 30 connected to the longitudinal bar 20.

For example, the suction cup gripping member 30 defines a gripping plane of the gripping device 10, which is for example parallel to the longitudinal axis A of the longitudinal bar A (and parallel to the flanking direction B), which for example ? substantially parallel to the upper surface (in view of the plate L gripped by the suction cup gripper 30 itself).

For example, the gripping device 10 comprises a plurality of of suction cup gripping members 30 each connected to the longitudinal bar 20, for example arranged along the longitudinal axis A of the same and separated from each other.

The suction cup gripping members 30 of the longitudinal bar 20 essentially share substantially the same gripping plane.

Each suction cup gripper 30 comprises a support frame 31 that can be anchored to the longitudinal bar 20 and at least one suction cup 32 fixed to the support frame 31.

For example, to improve the lifting operations of the slab L ? especially when heavy and/or ? flexible ? ? it is possible to provide that the sucker 32 is associated in an oscillating manner (with a limited oscillation) with respect to the longitudinal bar 20, for example with respect to an axis of oscillation parallel to the longitudinal axis A of the longitudinal bar 20 or with respect to an axis of oscillation orthogonal to the longitudinal axis A (e.g. parallel to the flanking direction B) or a combination of oscillations.

In this way, the suction cup 32 can? follow the different orientations or folds or curvatures of plate L while remaining with its gripping surface always parallel to the gripping surface of plate L.

For example, the 32 suction cup can? be associated in an oscillating manner (tilting) with respect to the support frame 31, which ? rigidly connected to the longitudinal bar 20, it is not excluded that on the contrary the support frame 31 could be associated in an oscillating manner to the longitudinal bar and the suction cup 32 rigidly fixed to the support frame 31.

For example, the suction cup 32 can? be variously configured in the oscillating or fixed configuration with respect to the longitudinal bar 20 by tightening means for blocking the oscillation, for example resolvable as threaded members.

Each suction cup gripping member 30 can? include a (as shown) or more? grouped suckers.

Each suction cup gripping member 30 can? for example be equipped with a vacuum pump (manual or electric) and a vacuum gauge.

Each suction cup gripping member 30 can? be fixed to the longitudinal bar 20 in any axial position of the same as will appear better? in the sequel. For example, a first suction cup gripper 30? connected to the first longitudinal member 21, for example in one (any) axial position interposed between the extremity? internal and the extremity? external, for example pi? close to the end? external that at the extremity? internal.

For example, a second suction gripper 30? connected to the second longitudinal member 22, for example in an (any) axial position interposed between the extremity? internal and the extremity? external, for example pi? close to the end? external that at the extremity? internal.

For example the support frame 31 of the (first and second) suction cup gripping member 30 comprises a fixing bracket able to removably fix the support frame 31 to one of the first longitudinal member 21 and the second longitudinal member 22, for example at the first side wall of the same equipped with the respective slot 210,220.

According to an advantageous aspect of the present invention, the suction cup gripping elements 30, in particular, the first suction cup gripping element 30 and the second suction cup gripping element 30, are arranged on the same side of the longitudinal bar 20 to which they are fixed .

In other words, the suction cup gripping members 30 fixed to the longitudinal members 21, 22 which define the longitudinal bar 20 are arranged (mainly or totally) to the side and on the same side with respect to a median longitudinal plane passing through the longitudinal axis A of the longitudinal bar 20 orthogonal to the side-by-side direction B of the same (that is, orthogonal to the visible surface of the gripping plate L).

In greater detail, the suction cup gripping members 30, i.e. the median planes of the respective suction cup 32 parallel to the aforementioned longitudinal median plane of the longitudinal bar 20, are both arranged to the right or to the left of the longitudinal bar 20.

In practice, one of the sucker gripping members 30 ? placed proximal to the first lateral wall provided with the slot 210,220 of the respective longitudinal member 21,22, and distal from the opposite second lateral wall, the other suction cup gripping organ 30?, on the other hand, placed proximal to the second lateral wall of the respective longitudinal member 21,22 , and distal from the first lateral wall having the groove 210,220.

In the illustrated example, the first suction cup gripping member 30 is placed proximal to the first side wall equipped with the slot 210 of the respective first longitudinal member 21 and distal to the opposite second side wall, while the second suction cup gripping member 30 is placed proximal to the second lateral wall of the respective second longitudinal member 22 and distal to the first lateral wall provided with the groove 220.

To do this, the support frame 31 of the suction cup gripping members 30, i.e. of the first suction cup gripping member 30 and of the second suction cup gripping member 30 are different from each other as it will appear better. in the sequel.

In particular, the support frame 31 which supports the suction cup grip member 30 proximal to the first side wall equipped with the slot 210,220 of the respective longitudinal member 21,22, in the example the first suction cup grip member 30 fixed to the first longitudinal member 21 , comprises a first fixing bracket (of a first type). The first fixing bracket of the support frame 31 comprises a first ?C? shaped plate, with concavity? facing the respective side member 21, 22 (ie the first side member 21), in particular towards the first side wall of the same, which? adapted to at least partially embrace the respective longitudinal member 21,22, for example in correspondence with the first side wall provided with the slot 210,220 and with the adjacent upper and lower base walls.

At the first shaped plate? fixed a shaped pin (or nut) by means of a threaded member.

The shaped plug? inserted (by means of a prismatic connection) inside the quarry 210,220, in particular of the first quarry 210, with the possibility? to slide along the longitudinal axis of the same without being able to be removed transversely and the threaded member protrudes transversely from the slot 210,220 and ? connected to the first shaped plate.

The first fixing bracket of the support frame 31 ? adapted to be locked (temporarily and adjustable) axially along the longitudinal axis of the respective side member 21,22, or of the first side member 21, by tightening the threaded member, which ? equipped with a knob or a locking lever, in the example a cam lever.

To the first fixing bracket of the support frame 31 ? fixed a lower support plate (substantially at right angles to the first side wall provided with the slot 210,220) which supports the suction cup 32, so that this protrudes below a plane defined by the lower base wall (facing the plate L in operation) of the respective side member 21,22.

On the other hand, the support frame 31 which supports the suction cup grip member 30 proximal to the second side wall (i.e. the one not equipped with the slot 210,220) of the respective longitudinal member 21,22, in the example the second suction cup grip member 30 fixed to the second longitudinal member 22, comprises a second fixing bracket (of a second type).

The second fixing bracket of the support frame 31 comprises a first ?C?-shaped plate, with concavity? facing the respective side member 21, 22 (or the second side member 22), in particular towards the first side wall of the same, which? adapted to at least partially embrace the respective longitudinal member 21,22, for example in correspondence with the first side wall provided with the slot 210,220 and with the adjacent upper and lower base walls.

To the second shaped plate ? fixed a shaped pin (or nut) by means of a threaded member.

The shaped plug? inserted (by means of a prismatic connection) inside the quarry 210,220, in particular of the second quarry 220, with the possibility? to slide along the longitudinal axis of the same without being able to be removed transversely and the threaded member protrudes transversely from the slot 210,220 and ? connected to the second shaped plate.

The second support frame fixing bracket 31 ? adapted to be locked (temporarily and adjustable) axially along the longitudinal axis of the respective side member 21,22, or of the second side member 22, by tightening the threaded member, which ? equipped with a knob or a locking lever, in the example a cam lever.

To the second support frame fixing bracket 31 ? fixed a second support plate to the upper U-bolt, which ? suitable for surmounting the upper base wall of the respective side member 21, 22, in the example of the second side member 22.

In particular, this U-bolt support plate comprises a first flap parallel (and resting) on the upper base wall of the respective side member 21,22 and a second flap parallel to the side walls of the respective side member 21,22, in particular, parallel to and distance from the second side wall (not provided with the slot 210,220).

In greater detail, the second flap ? placed at a distance from the second lateral wall (not provided with the slot 210,220) of the respective longitudinal member 21,22, or of the second longitudinal member 22, of a distance at least equal (or slightly greater) to the width of the other longitudinal member 21,22, or of the first side member 21 (i.e. the width of the base walls of the same).

Basically, the U-bolt support plate fixed to one of the longitudinal members 21, 22, in the example the second longitudinal member 22, is? shaped so as to define a passage channel within which ? able to slide axially the other longitudinal member 21, 22, in the example the first longitudinal member 21, when the two longitudinal members 21 slide reciprocally due to the variation of the length of the longitudinal bar 20.

The end? lower free part of the (second flap of the) U-bolt support plate supports the suction cup 32, so that it protrudes below a plane defined by the lower base wall (facing the slab L in operation) of the respective longitudinal member 21, 22.

The suckers 32 of each sucker gripping member 30 are aligned along an alignment direction parallel to the longitudinal axis of the longitudinal bar 20, ie the median planes of the suckers 32 parallel to said longitudinal median plane of the longitudinal bar 20 coincide.

Furthermore, the distance between the (lower) gripping surface of the suction cup 32 and the lower base wall of the respective side member 21,22 ? minimal, for example? substantially between 10 mm and 60 mm.

It is not excluded that pi? of a suction cup gripping member 30 can be fixed to the respective longitudinal member 21, 22, for example as described above.

Furthermore, it is not excluded that the suction cup gripping units can be mounted so that they are not aligned and all on the same side of the longitudinal bar 20, if the requirements so require.

Furthermore, a third suction cup gripper 30 may be connected to the guide tube 23.

For example, the third suction cup gripper 30 ? rigidly connected to the guide tube 23 (ie it is fixed in a solid way with it or in a removable way according to the needs?).

In particular, the support frame 31 of the third suction cup gripping member 30 is fixed directly, for example by welding, to the tubular body of the guide tube 23, for example in correspondence with an external side wall of the same parallel to the first side wall of one of the two side members 21,22 equipped with the respective slot 210,220.

The support frame 31 ? equipped with a support plate (substantially at right angles to the side wall of the tubular body to which the support frame 31 is associated) which supports the suction cup 32, so that it extends below a plane defined by the lower wall ( facing the plate L in operation) of the tubular body of the guide sleeve 23.

Also this third suction cup gripping member 30 can be arranged (mainly or totally) on the same side of the longitudinal bar 20 in which the other (first and second) suction cup gripping members 30 are arranged, preferably aligned with them, or having the median plane (parallel to the aforementioned median longitudinal plane of the longitudinal bar 20) of the respective suction cup 32 substantially coinciding with the median planes (parallel to said longitudinal median plane of the longitudinal bar 20) of the suction cups 32 of the other first and second) suction cup gripping members 30.

The suckers 32 of each suction cup gripping member 30 (first, second and third) are then substantially coplanar, i.e. they have lower gripping surfaces coplanar to each other and lying on a (single) plane, i.e. the aforementioned gripping plane, parallel to the longitudinal axis A of the longitudinal bar 20 (and parallel to the side by side direction B), so that they can all adhere to the (same) visible surface of a plate L.

In the event that the suction cups 32 of each suction cup gripping member 30 (first, second and third) are associated in an oscillating/tilting manner with the longitudinal bar 20, as described above, they are coplanar (i.e. they share the same grip plane) when the surface of the slab L ? gliding or when they are free; if they adhere to a structured/corrugated surface, the suction cups 32 all belong to this surface (which can be defined as a gripping plane).

The gripping device 10 generally comprises a handle 43, ie a region (rigidly fixed to or defined integral with the longitudinal bar 20) which is adapted to be gripped by an operator's hand for lifting, moving and transporting the gripping device 10 (and the plate L connected to it).

In the illustrated example, the handle 43 ? defined as a separate body from the longitudinal bar 20, or from the side members 21,22 which constitute it, as will be better? described below.

However, it is not excluded that the handle 43 can be defined integral with the longitudinal bar 20, or with the longitudinal members 21, 22 which constitute it, for example being defined by an end portion? (at or near the outer end) of the same.

In the illustrated example, the gripping device 10 comprises at least one handle 40 which ? connected to the longitudinal bar 20.

For example, handle 40 ? equipped with the aforementioned handle 43, how best will it be? described below.

Preferably, the gripping device 10 comprises a pair of handles 40 (each equipped with a respective handgrip 43), each connected to the longitudinal bar 20, for example separated along the longitudinal axis A of the same and arranged close to the of opposite ends? of the longitudinal bar A.

In practice, the handles 40 (and the respective grips 43) are arranged on opposite sides (and mutually opposite) with respect to the gripping device 10, i.e. of the longitudinal bar 20.

In general, the grip 43 has a longitudinal axis parallel (and eccentric) to the longitudinal axis A of the longitudinal bar 20.

The handle 43, in general, can? be covered or made of an anti-slip material, such as rubber or plastic or other material suitable for being gripped steadily by the user?s hand.

For example, the handle 43 ? covered by a shaped knob.

Each handle 40 can be fixed to the longitudinal bar 20 in any axial position of the same as will appear better? in the sequel.

For example, a first handle 40 ? connected to the first longitudinal member 21, for example in one (any) axial position of the same, interposed between the extremity? internal and the extremity? external, for example in the vicinity? or at the end? external of the same.

For example, a second handle 40 ? connected to the second longitudinal member 22, for example in one (any) axial position of the same, interposed between the extremity? internal and the extremity? external, for example in the vicinity? or at the end? external of the same.

According to an advantageous aspect of the present invention, the handles 40, in particular the first handle 40 and the second handle 40, are arranged on the same side of the longitudinal bar 20 to which they are fixed.

In other words, the handles 40 fixed to the longitudinal members 21, 22 which define the longitudinal bar 20 are arranged (mainly or totally) to the side and on the same side with respect to a median longitudinal plane passing through the longitudinal axis A of the orthogonal longitudinal bar 20 to the juxtaposition direction B of the same (that is orthogonal to the visible surface of the gripping plate L).

In greater detail, the handles 40, or at least their grips 43 (which define the gripping portions of the handle 40), are both arranged to the right or to the left of the longitudinal bar 20.

In practice, one of the handles 40 ? placed proximal to the first lateral wall provided with the slot 210,220 of the respective longitudinal member 21,22, and distal from the opposite second lateral wall, the other handle 40 ?, on the other hand, placed proximal to the second lateral wall of the respective longitudinal member 21,22, and distal from first side wall equipped with slot 210,220.

In the illustrated example, the first handle 40 ? placed proximal to the first side wall equipped with the slot 210 of the respective first longitudinal member 21 and distal to the opposite second side wall, while the second handle 40 is placed placed proximal to the second lateral wall of the respective second longitudinal member 22 and distal to the first lateral wall provided with the groove 220.

Each handle 40 has an anchoring bracket 41 able to removably fix the handle 40 to one of the first longitudinal member 21 and the second longitudinal member 22, for example in correspondence with the first side wall of the same having the respective slot 210,220.

To do this, the anchoring brackets 41 of the handles 40, i.e. of the first handle 40 and of the second handle 40, are different from each other as it will appear better. in the sequel.

In particular, a first anchoring bracket 41 (of a first type) supports the handle 40 proximal to the first side wall provided with the slot 210,220 of the respective longitudinal member 21,22, in the example the first handle 40 fixed to the first longitudinal member 21.

The first anchoring bracket 41 comprises a ?C? shaped plate? or quill (closed section), with concavity? facing the respective side member 21,22, in particular of the first side member 21, or towards the first side wall provided with the slot 210,220, and ? adapted to embrace at least partially (or totally) the perimeter of the respective longitudinal member 21,22, for example in correspondence with the first side wall provided with the slot 210,220 and with the adjacent upper and lower base walls (and possibly also with the second side wall). To the anchor bracket shaped plate 41 ? fixed a shaped pin (or nut) by means of a threaded member.

The shaped plug? inserted (by means of a prismatic connection) inside the quarry 210,220 with the possibility? to slide along the longitudinal axis of the same without being able to be removed transversely and the threaded member protrudes transversely from the slot 210,220 and ? connected to the shaped plate.

The first anchor bracket 41 ? adapted to be locked (temporarily and adjustable) axially along the longitudinal axis of the respective side member 21,22 by tightening the threaded member, which ? equipped with a knob or a locking lever, in the example of the cam type.

The first anchoring bracket 41 then comprises a first bridge 42 provided with one end? whose extremity? free ? rigidly connected (for example welded) to the shaped plate and an opposing extremity? free.

The extremity? free and an axial section (substantially cylindrical) proximal to this end? free of the first bridge 42 defines a first handle 43 which can be grasped by an operator's hand.

This first handgrip 43 has a longitudinal axis substantially parallel to the longitudinal axis of the respective longitudinal member 21, 22, or of the first longitudinal member 21, to which it? fixed.

Instead, a second anchoring bracket 41 (of a second type) supports the handle 40 proximal to the second side wall (not equipped with the slot 210,220) of the respective side member 21,22, in the example the second handle 40 fixed to the second side member 22.

The second anchoring bracket 41 comprises a ?C? shaped plate? or quill (closed section), with concavity? facing the respective longitudinal member 21,22, in particular towards the second longitudinal member 22, or towards the first lateral wall provided with the slot 210,220 thereof, and ? adapted to embrace at least partially (or totally) the perimeter of the respective longitudinal member 21,22, for example in correspondence with the first side wall provided with the slot 210,220 and with the adjacent upper and lower base walls (and possibly also with the second side wall).

To the shaped plate of the second anchor bracket 41 ? fixed a shaped pin (or nut) by means of a threaded member.

The shaped plug? inserted (by means of a prismatic connection) inside the quarry 210,220 with the possibility? to slide along the longitudinal axis of the same without being able to be removed transversely and the threaded member protrudes transversely from the slot 210,220 and ? connected to the shaped plate.

The second anchor bracket 41 ? adapted to be locked (temporarily and adjustable) axially along the longitudinal axis of the respective side member 21,22 by tightening the threaded member, which ? equipped with a knob or a locking lever, in the example of the cam type.

The second anchoring bracket 41 then comprises a second bridge 42 (different from the first bridge 42) provided with one end? whose extremity? free ? rigidly connected (for example welded) to the shaped plate and an opposing extremity? free.

The second jumper 42 ? configured so as to surmount (at a distance) the upper base wall of the respective side member 21,22, in the example of the second side member 22.

The extremity? free and an axial section (substantially cylindrical) proximal to this end? free of the second bridge 42 defines a second handle 43 which can be grasped by an operator's hand.

This second handle 43 has a longitudinal axis substantially parallel to the longitudinal axis of the respective longitudinal member 21, 22, or of the second longitudinal member 22, to which it? fixed.

Preferably, this second handle 43 is arranged on the same side (to the side) of the first handle 43 with respect to the longitudinal bar A, more? preferably the first handle 43 and the second handle 43 are coaxial (and opposite) to each other.

Again, in the example, both handles 40 of the same longitudinal bar 20 (or the grips 43 of the same) are arranged on the same side of the longitudinal bar 20 in which (all) the suction cup gripping units 30 (or the respective suckers 32 of the same).

Pi? in detail, the axes of the grips 43 of both handles 40 lie on a plane coinciding with the (common) median planes of the suckers 32 parallel to the aforementioned longitudinal median plane of the longitudinal bar 20.

According to an advantageous aspect, then, the first handle 40 defines a mechanical limit switch (matching with the guide tube 23) for the axial sliding of the first longitudinal member 21 in its second extreme position and the second handle 40 defines a mechanical limit switch ( abutting with the guide tube 23) for the axial sliding of the second longitudinal member 22 in its second extreme position.

The anchoring bracket 41 of a handle 40, be it the first handle or the second handle described above, could have an indicator, for example a slot or a through hole (possibly highlighted with a visual indication, such as for example a arrow or similar), which ? configured to indicate a mutual end-of-stroke position between the handle 40 and the longitudinal member of the longitudinal bar 20 at which ? fixed, for example at the extremity? external of the same.

In practice, through the?indicator when the handle 40 ? inserted on the respective spar 21,22? is it possible to see the extremity? external, thus ? it is possible to visually check the correct reciprocal positioning between the handle 40 and the respective longitudinal member 21,22.

Furthermore, the anchoring bracket 41 of a handle 40, be it the first handle or the second handle described above, could also have a further indicator, for example a further slot or a through hole (possibly highlighted with a visual indication, such as for example, an arrow conformation or similar), which ? configured to indicate a position of maximum longitudinal encumbrance of a plate L that can be gripped with the aforementioned gripping device 10.

In practice, through the? indicator when the slab L ? being gripped by the suction cup gripping members 30 ? Is it possible to predict not to see an extremity? free of the slab or at least see the perimeter edge, in this way ? possible to visually check the correct positioning of the slab L with respect to the gripping device 10.

The gripping device 10 comprises, for example, a hinge seat 45, the function of which will be? clarified below.

For example, the hinge seat 45 can be defined on a longitudinal bar 20, for example one of the longitudinal members which constitute it, preferably at or near the? of one end? axial of the same (for example in correspondence or in proximity? of the external end? of one of the side members). Preferably, the hinge seat 45 is made at a handle 40, preferably at an anchoring bracket 41 of a handle 40, whether it is the first handle or the second handle described above.

The hinge seat 45, preferably, is defined by an (elongated) slot having a through axis orthogonal to the longitudinal axis A of the longitudinal bar 20 (and parallel to the flanking direction B).

For example, the hinge seat 45 (i.e. the slot) has a semi-cylindrical upper closed portion (whose central axis coincides with the aforementioned through axis) and a lower open portion (defining an access mouth for the hinge seat 45 itself).

In practice, the hinge seat 45 overall has a concavity facing the side of the gripping surface (ie facing in accordance with the suction cups 32 of the suction cup gripping member 30).

The lower open portion is, for example, delimited by two opposing walls (for example parallel), which are inclined backwards, i.e. so as to move away (progressively) from the end? free of the longitudinal bar 20 and/or of the handle 40.

The gripping device 10 comprises a foot 50 which ? connected to the longitudinal bar 20, for example at one end? axial of the same.

The 50 foot ? adapted to facilitate the overturning operations of the sheet L, for example on the smaller side of the same.

The gripping device 10 comprises, in the example, a pair of feet 50 each connected to the longitudinal bar 20, for example one for each of the opposite ends. of the longitudinal bar A.

Each foot 50 pu? be anchored to the longitudinal bar 20 as will appear better? in the sequel.

Each foot 50 ? slidably connected to the longitudinal bar 20 and so that its position is adjustable along the longitudinal axis A of the longitudinal bar 20 between a retracted position, in which ? at least partially contained in the longitudinal space of the longitudinal bar 20 (or at least in substance it is close to one end of the longitudinal bar to which it is constrained), and an extracted position, in which it extends axially on one side the longitudinal bar 20 and extends lengthwise from it.

For example, each foot comprises at least one soft end portion, for example made of rubber.

A first foot 50 ? connected to the first spar 21, for example in the vicinity? or at the end? external of the same.

A second foot 50 ? connected to the second spar 22, for example in the vicinity? or at the end? external of the same.

Each foot 50 comprises blocking means adapted to block the axial sliding of the foot 50 in the retracted position, in the extracted position and in any axial position interposed between the retracted position and the extracted position. In the example, the foot 50 ? integrally fixed to the handle 40, or ? integral with it, for example at the extremity? free of the anchoring bracket 41 of the latter (or of the bridge 42), so as to axially extend the handle itself, or its handle 43.

In the example, a foot 50 ? fixed to each handle 40, for example at the end? free of the respective handle 43.

Advantageously, a foot 50 can? be associated with each of the handles 40 (provided with the hinge seat 45 described above).

In particular, the foot 50 pu? be fixed to the anchoring bracket 41, for example at? free of the same (that is facing the opposite side of the spar to which it is associated).

The end? free of this foot (fixed to the anchoring bracket 41) ? located at a predetermined non-zero distance from the through axis (i.e. the central axis of the upper closed portion) of the hinge seat 45.

For example, a first foot 50 (fixed to the anchor bracket 41) can be arranged substantially coaxial to the longitudinal bar 20 (or to the longitudinal axis of the respective side member), so as to extend it axially.

That first foot 50 ? configured to support the gripping device 10 (and the gripping plate L) in stable support on the ground in a substantially vertical position, i.e. with the gripping plane arranged substantially vertical, or slightly inclined backwards, for example leaning against a wall vertical by means of the opposite handle 43.

In this substantially vertical position, on the lower laying surface of the slab L (gripped by the gripping device 10) can? be applied a layer of glue to facilitate installation (according to the known procedure, the so-called ?double spreading?).

For example, a second foot 50 (fixed to the anchor bracket 41) can be arranged at a given angle with respect to the longitudinal axis A to the longitudinal bar 20 (or to the longitudinal axis of the respective side member).

In particular this second foot 50 ? placed below, i.e. towards the gripping surface, and has an axis inclined with respect to the longitudinal axis A of the longitudinal bar, for example by a predetermined acute angle facing the opposite side with respect to the longitudinal bar 20.

Preferably, the predetermined angle ? essentially equal to 45? (?15?). That second foot 50 ? configured to support the gripping device 10 (and the gripping plate L) in stable support on the ground in a position substantially inclined with respect to the vertical, ie with the gripping surface arranged substantially inclined with respect to the vertical (towards the operator).

In practice, the second foot 50 ? configured to define a transitory anti-slip support on the ground for the gripping device 10 and/or for the transport and/or placing device 1, in the overturning action (from the horizontal position to the vertical position) of the gripping device 10 (and of the grip plan of the same). This second foot 50 makes it possible to exert an effective push towards the vertical position, avoiding slippage or sliding of the ground support point of the transport and/or laying device 1.

In a first possible embodiment (see figures 1 and 2), the gripping device 10 comprises a single longitudinal bar 20, with respective suction cup gripping members 30 (handles 40 and feet 50), as described above.

In a second possible embodiment, not shown in the figures, the gripping device 10 comprises two (or more?) longitudinal bars 20, with respective suction cup gripping members 30 (handles 40 and feet 50), as described above, for example equal to each other (and independent of each other).

For example, the longitudinal bars 20 are used parallel to each other or obliquely (i.e. with substantially intersecting longitudinal axes A), so that the respective suction cups 32 (coplanar, i.e. such as to share the same grip plane) adhere removably to the surface in view of the (same) plate L.

Preferably, but not limited to? It is possible to arrange the pair of longitudinal bars so that the respective suction cup gripping members 30 (or the suction cups 32 thereof) and the respective handles 40 (or the grips 43 thereof) are opposite, i.e. external to the two longitudinal bars 20 .

The gripping device 10, in this second embodiment, is therefore consisting of the two longitudinal bars 20 (identical) placed side by side with respect to the side by side direction B (orthogonal to the longitudinal axis A of the longitudinal bars 20 and parallel to the plane defined by the suction cups 32 or to the plane defined by the surface to be taken of the slab L) and, for example, substantially parallel to each other or in any case positionable according to need, so that the suction cup gripping members 30 of both longitudinal bars 20 grip a visible surface of a single slab L.

At least one? extremity? axial axis of the gripping device 10 (preferably both opposite axial ends) is, therefore, equipped with a pair of grips 43 (adapted to be gripped with both hands of an operator).

For example, preferably the two longitudinal bars 20 are arranged in a staggered (or anti-symmetrical) manner, i.e. the first longitudinal member 21 of each of the longitudinal bars 20? facing (along the side by side direction B) the second longitudinal member 22 of the other longitudinal bar 20.

In this configuration, each opposite part of the gripping device 10 is equipped with a first handle 43 and a second handle 43 (arranged outside the longitudinal bars 20 along the side by side direction B).

In a third possible embodiment, shown in figures 3? 17, the gripping device 10 comprises two (or more?) longitudinal bars 20, with respective suction cup gripping members 30 (handles 40 and feet 50), as described above, for example equal to each other (and arranged in a staggered/ antisymmetric) and one or more? crosspieces 60 for connection and support between the two longitudinal bars 20.

Preferably, but not limited to? It is possible to arrange the pair of longitudinal bars so that the respective suction cup gripping members 30 (or the suction cups 32 thereof) and the respective handles 40 (or the grips 43 thereof) are opposite, i.e. external to the two longitudinal bars 20 .

Furthermore, in this third embodiment, the gripping device 10 comprises a cross member 60 connected to each longitudinal bar 20 of the pair of longitudinal bars 20.

For example, the crossbar 60 ? arranged substantially at right angles to the pair of longitudinal bars 20 which it joins or variously inclined according to the mutual inclination of the longitudinal bars 20, as best described below.

Preferably, the crosspiece 60 overall has a longitudinal axis substantially parallel to the plane defined by the visible surface of the gripping plate L and orthogonal or variously inclined (not parallel) to the longitudinal axis A of the longitudinal bars 20.

Traverse 60? placed on the same side of the longitudinal bars 20, i.e. above them. In other words, crossbar 60 ? located on the distal side of the gripping plate L, i.e. distal to the suckers 32 of the suction cup gripping members 30 (in practice, the crosspiece 60 surmounts the longitudinal bars 20 when the gripping device 10 and the plate L are horizontal).

The extremities? axial elements of the crosspiece 60 can define or comprise an auxiliary handle, i.e. a zone (rigidly fixed to or defined integral with the crosspiece 60) which ? adapted to be gripped by an operator's hand for lifting, moving and transporting the gripping device 10 (and the plate L connected to it).

Preferably, the auxiliary handle ? defined integral with the crosspiece 60 (or the bar/s that constitute it), for example being defined by an end portion? (at or near the outer end) of the same.

However, it is not excluded that the auxiliary handle may be defined as a body separate from the cross member 60, or from the bar/s which constitute it, for example being constructively similar to the handle 43 described above. The crossbar 60 can? be, for example, adjustable in length, how better will it be? described below.

The cross member 60 comprises a main bar 61 having a respective longitudinal axis and a (single) extension bar 62 having a relative longitudinal axis parallel to the longitudinal axis of the main bar 61.

The longitudinal axes of the main bar 61 and of the extension bar 62 overall define the longitudinal axis of the crosspiece 60.

The main bar 61 and the extension bar 62 are placed side by side with respect to a direction of mutual side by side orthogonal to their longitudinal axis (and parallel to the plane of arrangement of the plate L ? or of its visible surface ? in use).

The main bar 61 and the extension bar 62 are defined, individually, by longitudinal sections for example substantially rigid (not deformable in bending or torsion under the workloads of proper use of the gripping device 10). The main bar 61 has a substantially quadrangular section, for example rectangular, constant along the entire length.

For example, the main bar 61 ? obtained by extrusion of a metallic material, for example a light alloy (such as for example aluminum), and for example ? internally hollow (that is, it has a full length axial cavity, possibly equipped with full length internal stiffening partitions).

Preferably, therefore, the main bar 61 has a pair of lateral walls (substantially parallel to each other), for example orthogonal in use to the visible surface of the plate L being gripped, and a pair of base walls (substantially parallel to each other) at right angles and adjacent to the side walls, which are in use parallel to the visible surface of the gripping plate L.

The main bar 61 has, in correspondence with a first lateral wall thereof, a hollow 610, for example with a substantially dovetail or "T" shaped cross-section, extending entirely longitudinally.

Quarry 610 ? defined at the first major side wall of the main bar 61.

A second lateral wall, opposite to the first wall presenting the groove 610, for example comprises a shaped profile, for example with its entire longitudinal development.

Said shaped profile comprises, for example at least one facing tooth with its full extension and at least one (homologous) recessed recess with its full extension, parallel to each other.

The main bar 61, for example, pu? include one or two caps to close one end each? axial of the main bar 61 itself, or of the cavity? axial of the same.

The 62 extension bar ? for example completely similar (identical) to the main bar 61.

Preferably, the extension bar 62 has the same length as the main bar 61, for example it has the same shape and the same overall dimensions.

For example, the extension bar 62 has a substantially quadrangular section, for example rectangular, constant along the entire length.

Preferably, the extension bar 62 ? obtained by extrusion of a metallic material, for example a light alloy (such as for example aluminum), and for example ? internally hollow (that is, it has a full length axial cavity, possibly equipped with full length internal stiffening partitions).

Therefore the extension bar 62 has a pair of side walls (substantially parallel to each other), for example orthogonal in use to the visible surface of the plate L being gripped, and a pair of base walls (substantially parallel to each other) square and adjacent to the side walls, which are in use parallel to the visible surface of the gripping plate L.

The extension bar 62 has, in correspondence with a first side wall thereof, a hollow 620, for example with a substantially dovetail or "T" shaped cross-section, extending entirely longitudinally.

Quarry 620 ? defined at the first major side wall of the extension bar 62.

A second lateral wall of the extension bar 62, opposite to the first wall presenting the groove 620, for example comprises a shaped profile, for example with its entire longitudinal development.

Said shaped profile comprises, for example at least one facing tooth along its entire longitudinal development and at least one (homologous) recessed recess along its entire longitudinal development, parallel to each other.

The extension bar 62, for example, can? include one or two caps to close one end each? axial of the extension bar 62 itself, or of the cavity? axial of the same.

At one end? axial of the extension bar 62 pu? a spur 63 must be fixed, capable of facilitating the overturning operations of the slab L, for example on the longer side of the same or in any case capable of acting as an anti-fall safety device for the gripping slab L.

The main bar 61 and the extension bar 62 are side by side (with respect to the direction of mutual side by side) so that the second side walls opposite the first side walls having the slots 610,620 are substantially in contact with each other (by axial sliding) or slightly spaced.

The slots 610,620 are therefore mutually opposite (ie open in opposite directions).

In practice, the main bar 61 and the extension bar 62 slide one over the other, for example by defining a connection of the prismatic and/or sliding guide type.

This link? defined by the axially sliding engagement of the facing tooth of the main bar 61 in the recessed recess of the extension bar 62 and, at the same time, of the facing tooth of the extension bar 62 in the recessed recess of the main bar 61.

In practice, the main bar 61 and the extension bar 62 are at least partially interpenetrating each other.

Furthermore, the main bar 61 and the extension bar 62 are mutually symmetrical with respect to a plane of symmetry orthogonal to the direction of mutual juxtaposition (that is, orthogonal to the visible surface of the gripping plate L).

In general, the crossbar 60 ? variously configurable so as to be able to vary its length and/or its shape as it will appear better? in the sequel.

Preferably, the extension bar 62 of the crosspiece 60 is alternatively movable in reciprocal sliding with respect to the main bar 61 between a closed position, in which its longitudinal size is ? totally contained in the longitudinal dimensions of the main bar 61, and an open position in which the extension bar 62, i.e. one end thereof? axial, protrudes axially selectively from one or the other end? axial from the main bar 61.

In practice, in the closed position the axial dimensions (or axial length) of the crosspiece 60 coincides with the axial dimensions (or length) of the main bar 61, i.e. the main bar 61 and the extension bar 62 are side by side with respect to each other to the direction of mutual support and the opposite ends? of the extension bar 62 do not exceed/extend the respective ends? of the main bar 61, i.e. they are arranged substantially coplanar with them.

In the open position, on the other hand, the axial bulk (or axial length) of the cross member 60 is greater (or prolonged) than the axial bulk (or length) of the main bar 61, by a quantity? equal to the length of the axial section of extension bar 62 which protrudes axially beyond one of the two ends? main rod axles 61.

In the embodiment shown, the crosspiece 60 as a whole or each between the main bar 61 and the extension bar 62, for example, is which can be removably associated with each longitudinal bar 20, for example by means of a respective interconnecting body 70.

The crosspiece 60 as a whole or each between the main bar 61 and the extension bar 62? slidingly associated with each longitudinal bar 20 of the pair of longitudinal bars 20 with respect to a direction parallel to the longitudinal axis A of the longitudinal bars 20.

For example, the cross member 60 as a whole or each between the main bar 61 and the extension bar 62? lockable along the longitudinal bar 20 in any axial position thereof.

In practice, each interconnection body 70 ? configured to allow the cross member 60 to slide as a whole or each between the main bar 61 and the extension bar 62 along the longitudinal axis A of the respective longitudinal bar 20 and to lock it axially in any desired position.

In practice, each interconnection body 70 ? configured to connect the crosspiece 60 as a whole or each between the main bar 61 and the extension bar 62 to one of the side members 21, 22 of the longitudinal bar 20 and allow the crosspiece 60 to slide as a whole or each between the main bar 61 and the extension bar 62 along the longitudinal axis of the respective side member 21, 22 and the axial locking of the same in any desired position. For example, each interconnect body 70 ? positioned to connect the crosspiece 60 as a whole or each between the main bar 61 and the extension bar 62 to one of the longitudinal members 21, 22 in a central portion of the same axially interposed between the end? outer and the guide sleeve 23.

The interconnection body 70 comprises a support body 71, which ? configured as a tube and ? adapted to mutually constrain the main bar 61 and the extension bar 62 allowing/assisting a reciprocal longitudinal translation, i.e. along the longitudinal axis of the same and, therefore, the adjustment of the length of the crosspiece 60.

The support body 71 can? be of the type with cross section open, closed, made of one piece or in two or more? pieces depending on the construction needs, how better will it be? detailed below.

The support body 71 comprises a tubular body provided with a cavity through axial having a longitudinal axis substantially parallel (and coinciding) with the longitudinal axis of the cross member 60 as a whole.

For example, the cavity axial (and/or the tubular body) of the support body 71 has a substantially prismatic shape, for example with a quadrangular cross-section, for example substantially square or rectangular.

The cavity? of the support body 71 has a cross section, constant throughout its development, configured for (i.e. having a shape and a size such as) to be inserted, substantially to measure, (simultaneously) by both the main bar 61 and the extension bar 62 side by side as described above, or an intermediate section of the same interposed between their opposite ends?.

The axial length of the support body 71 ? decidedly contained, or its axial length? substantially equal to the width of the crosspiece 60 in the mutual side by side direction of the main bar 61 and the extension bar 62, i.e. the axial length of the support body 71 does not exceed twice the said width of the crosspiece 60.

The tubular body of the support body 71 ? for example a substantially rigid body (not deformable in longitudinal bending or torsion under the workloads of proper use of the gripping device 10).

Are the main bar 61 and the extension bar 62 both (simultaneously and individually) inserted axially inside the cavity? axial of the support body 71 with the possibility? to flow, independently, in relative sliding along the longitudinal direction given by the longitudinal axis of the cavity? of the support body 71 for adjusting the length of the crosspiece 60. For example, between the support body 71 and each of the main rod 61 and the extension rod 62 ? defined as a prismatic type mechanical connection. Preferably, the main bar 61 ? sliding inside the support body 71 between two opposing end working positions (defined for example by respective mechanical limit switches) and in infinite intermediate positions between them, in which it remains filled in the support body 71 (unless deliberately removed from it) .

The extension bar 62, on the other hand, ? sliding (freely) within the cavity? axial of the support body 71 in the two sliding directions with the possibility? to be withdrawn axially from the support body 71 if necessary.

In greater detail, the support body 71 ? configured to lock axially in any axial position relative to the cavity? of the support body 71, individually the main bar 61 and/or the extension bar 62 and/or simultaneously the main bar 61 and the extension bar 62.

In particular, the support body 71 comprises a first locking unit configured to temporarily block the individually axial sliding of the main bar 61 with respect to the support body 71 along the longitudinal axis of the support body 71 itself.

The first blocking unit comprises a fixing member capable of cooperating with the slot 610 of the main bar 61 for blocking the relative sliding between the support body 71 and the main bar 61 itself.

In detail, the fixing member comprises a shaped pin (or nut) to which connected a tie rod (e.g. threaded or unthreaded).

The shaped plug? inserted (by means of a prismatic connection) inside the hollow 610 of the main bar 61 with the possibility? to slide along the longitudinal axis of the same without being able to be removed transversely and the tie rod protrudes transversely from the slot 610 and ? inserted in a through hole made in a side wall of the support body 71 facing the side wall of the main bar 61 equipped with the slot 610.

The main bar 61 ? adapted to be blocked (temporarily and resolvable) axially along the longitudinal axis of the support body 71 by tightening the tie rod, which is equipped with a knob or a clamping lever, in the example a cam lever at its end? suitable to exert traction on the nut and, therefore, constrain (by friction) the support body 71 and the main bar 61.

The support body 71 then comprises a second locking unit for the temporary and solvable locking of the relative longitudinal sliding of the extension bar 62 (and/or of the cross member 60 as a whole) along the longitudinal axis of the support body 71 same.

For example, the passage light of the cavity? axial of the support body 71 ? variable and operable between an enlarged configuration, in which it allows the reciprocal sliding of the extension bar 62 with respect to the support body 71 (and to the main bar 61 fixed to it by the first locking unit), and a narrow configuration, in which it prevents or counteracts the mutual sliding of the extension bar 62 and the support body 71 (and of the main bar 61).

The second locking group? for example rigidly connected to the support body 71.

The second locking group? for example a clamping unit of the clamp type, i.e. capable of clamping the support body 71, i.e. its tubular body, mutually in a clamp (in a transverse direction with respect to the longitudinal axis of the crosspiece 60), with one or both bars, in particular the main bar 61 and the extension bar 62.

In the illustrated example, the support body 71, i.e. its tubular body, is made from the union of two coupled bodies.

For example, the support body 71 comprises a first shell, for example comprising a ?C?-shaped open cross section, and a second shell, for example substantially plate-shaped, able to close the open section of the first shell.

The first shell and the second shell have respective lugs suitable for facing each other for fastening, by means of clamping members, for example threaded, of the first shell to the second shell.

In the example, the first shell and the second shell each have an ear at each end? of contact between the shells.

For example, each lug of the first shell has at least one through hole adapted to be aligned with its through axis to a through hole made in the respective lug of the second shell.

The through holes are threaded by a clamping member.

In this first embodiment, the clamping member comprises a threaded pin inserted in the through holes, locked axially, for example by means of a nut or by screwing, to one of the through holes, and equipped with an actuation member, for example a prismatic head and/or a cam lever associated with one end? of the threaded pin distal from the through hole to which ? the threaded pin blocked.

One of the two ears of each shell ? bound by clamping members having a prismatic head (for example the lower ears), while the other of the ears of each shell ? constrained by clamping members having a cam lever.

The cam lever of the second locking unit is, for example, placed at the side wall of the support body 71 opposite to that carrying the cam lever of the first locking unit.

The clamping organ ? operable (manually) for the release and reciprocal tightening of the first shell and the second shell, so as to bring the cavity? of the support body 71 respectively in its enlarged configuration, in which it allows the axial sliding of the extension bar 62 (and possibly of the main bar 61 if released by the first locking unit) inside it, and in its narrow position, in which prevents (by friction) or opposes the sliding of the extension bar 62 (and/or of the main bar 61) inside it.

In this configuration, the second locking group? therefore defined by the same tubular body as the support body 71, which acts as a vice, the jaws of which are the first shell and the second shell.

In general, the support body 71 can? include holes or lightening gaps.

Again, the interconnection body 70 comprises an interconnection bracket 72 able to connect, for example in a removable way, to the longitudinal bar 20. Preferably, the interconnection bracket 72 comprises a first flap able to be arranged parallel to the first side wall provided with the quarry 210.220 of one of the side members 21.22.

For example, the first flap of the interconnecting bracket 72 can? be fixed a shaped pin (or nut) by means of a threaded member which engages a through hole made in the first flap itself, in the example an elongated slot, with a longitudinal axis parallel to the slot 210,220 of the side member 21,22 to which ? fixed and, preferably axially open.

The shaped plug? inserted (by means of a prismatic connection) inside the quarry 210,220 of one of the side members 21,22 with the possibility? to slide along the longitudinal axis of the same without being able to be removed transversely and the threaded member protrudes transversely from the slot 210,220 of the side member 21,22 and ? inserted in the elongated buttonhole.

The first flap of the interconnecting bracket 72 can? be locked (temporarily and adjustable) axially along the longitudinal axis of the side member 21,22 by tightening the threaded member, which ? equipped with a locking lever or knob, in the example a locking knob.

The elongated open buttonhole allows a more? rapid removal of the interconnecting bracket 72 from the side members 21,22 in case the cross member 60 has to be removed from them.

It is not excluded that the first flap of the interconnection bracket 72 is not locked tightly, but that it can slide substantially freely axially along the longitudinal axis of the side member 21,22.

Furthermore, the interconnection bracket 72 has a second flap arising (cantilevered) from the top? (upper) of the first flap at right angles to it and in fact parallel to the lower base wall of the cross member 60 and integral with the first flap. In practice, the first flap and the second flap give the interconnection bracket 72 a substantially "L" shape.

For example, the second roof defines an (indirect) support plane for the crossbar 60.

The second layer? associated (lower) to the support body 71, how better will it be? described below.

Preferably, the interconnecting body 70 defines as a whole a hinged joint configured to allow any mutual orientation between the crosspiece 60 and the longitudinal bar 20.

In detail, the hinged joint comprises a (single) hinge axis C orthogonal to the longitudinal axis of the longitudinal bar A and to a longitudinal axis of the crosspiece 60, ie substantially orthogonal to the visible surface of the plate L being gripped.

Preferably, the interconnection bracket 72, or its second flap, and the support body 71, or a lower face thereof, are rotatably coupled to each other around the aforementioned hinge axis (orthogonal to both the second flap and the lower face themselves) .

For example a hinge pin, defined for example by a threaded bolt, engages a first cylindrical seat made in the lower wall and a second seat made in the second flap.

The hinge joint, defined by the pivotal connection between the support body 71 and the interconnecting bracket 72, can present a predetermined resistance (not zero or in any case adjustable/adjustable by means of the action on the threaded bolt) to the spontaneous reciprocal rotation (obtained by calibrating the friction involved). For example, this resistance to spontaneous reciprocal rotation ? configured in such a way as to prevent the spontaneous rotation between the support body 71 and the interconnection bracket 72 around the hinge axis C when not solicited by a suitable circumferential force (voluntary by the operator).

On the other hand, it cannot be excluded that the hinged joint is free or that - on the contrary - the interconnection bracket 72 and the support body 71 are fixed to each other without any degree of freedom. reciprocal.

Thanks to the aforementioned interconnection body 70 ? possible to keep the longitudinal bars 20 parallel and coplanar to each other and placed side by side with respect to the side by side direction B and/or allow that, depending on the shape of the slab L, the longitudinal bars are used inclined (and coplanar) to each other, i.e. with longitudinal axes Basically accidents.

In the same way, the crosspieces 60 can also be arranged with longitudinal axes parallel to each other (and orthogonal to the longitudinal axes of the longitudinal bars 20) or alternatively they can be arranged with longitudinal axes incident to each other (and inclined by any right angle or angle different from the ?right angle to the longitudinal axes of the longitudinal bars 20).

In an advantageous embodiment, the crosspiece 60 as a whole or each between the main bar 61 and the extension bar 62 can be slidably associated with each longitudinal bar 20 of the pair of longitudinal bars 20 with respect to a direction perpendicular to the longitudinal axis A of the respective longitudinal bar 20 (by means of the sliding connection between the first flap of the interconnection bracket 72 and the slot 210,220 of the respective spar 21.22).

In particular, the crossbar 60 as a whole or each between the main bar 61 and the extension bar 62 can be associated with each longitudinal bar 20 with the possibility? to slide with respect to a direction orthogonal to the plane defined by the suction cups 32, i.e. the plane defined by the upper surface (in view) of the plate L.

Each crosspiece 60 as a whole or each between the main bar 61 and the extension bar 62? fixed to a longitudinal bar 20 by means of a respective interconnecting body 70 as described above.

The gripping device 10 comprises at least one further suction cup gripping member 30, or a fourth suction cup gripping member 30, connected to the crosspiece 60 as a whole or to one of the main bar 61 and the extension bar 62, preferably at the extension bar 62.

The further fourth suction cup gripping member 30 comprises a support frame 31 which can be anchored to the crosspiece 60, or to the extension bar 62, and at least one suction cup 32 fixed to the support frame 31.

For example, to improve the lifting operations of the slab L ? especially when heavy and/or ? flexible ? ? it is possible to provide that the sucker 32 is associated in an oscillating manner (with a limited oscillation) with respect to the crosspiece 60, for example with respect to an oscillation axis parallel to the longitudinal axis A of the longitudinal bar 20 or with respect to an orthogonal oscillation axis to the longitudinal axis A (for example parallel to the side by side direction B) or parallel to the longitudinal axis of the cross member 60 or a combination of oscillations.

In this way, the suction cup 32 can? follow the different orientations or folds or curvatures of plate L while remaining with its gripping surface always parallel to the gripping surface of plate L.

For example, the 32 suction cup can? be associated in an oscillating manner (tilting) with respect to the support frame 31, which ? rigidly connected to the crosspiece 60, it is not excluded that on the contrary the support frame 31 could be associated in an oscillating manner with the crosspiece 60 and the suction cup 32 rigidly fixed to the support frame 31.

For example, the suction cup 32 can? be variously configured in the oscillating or fixed configuration with respect to the crosspiece 60 by tightening means for blocking the oscillation, for example resolvable as threaded members.

The further fourth suction cup gripping member 30 can? include a (as shown) or more? grouped suckers.

The further fourth suction cup gripping member 30 can? be equipped, for example, with a respective vacuum pump and a respective vacuum gauge.

The further fourth suction cup gripping member 30 can? be fixed to the crosspiece 60, or of the extension bar 62, in any axial position of the same as will appear better? in the following, for example at the center line of the same or in the vicinity? of one end? of the crosspiece 60, or of the extension bar 62, according to the gripping requirements.

The support frame 31 comprises a fixing leg able to flank the first side wall equipped with the slot 620 of the extension bar 62.

At the fastening leg ? fixed a shaped pin (or nut) by means of a threaded member.

The shaped plug? inserted (by means of a prismatic connection) inside the slot 620 of the extension bar 62 with the possibility to slide along the longitudinal axis of the same without being able to be withdrawn transversely and the threaded member protrudes transversely from the slot 620 and ? connected to the fixing leg.

The support frame 31 ? adapted to be locked (temporarily and adjustable) axially along the longitudinal axis of the crosspiece 60, or of the extension bar 62, by tightening the threaded member, which ? equipped with a knob or a lever or a locking nut, in the example a locking knob.

The support frame 31 therefore supports the suction cup 32, so that it extends below a plane defined by the lower base wall (facing the slab L in operation) of the crosspiece 60, or of the extension bar 62 .

The sucker 32 of the further fourth sucker gripping member 30 ? substantially coplanar to the suction cups 32 of each suction cup gripping member 30 (first second and/or third) of the gripping device 10, i.e. they have gripping surfaces coplanar to each other and lying on a plane parallel to the longitudinal axes A of the longitudinal bars 20, so that they can all adhere to the (same) upper surface of the slab L.

In the event that the suction cups 32 of each suction cup gripping member 30 (first, second, third and fourth) are associated in an oscillating/tilting manner with the longitudinal bar 20 and with the crosspiece 60, as described above, they are coplanar when the surface of the L slab? gliding or when they are free; if they adhere to a structured/corrugated surface, the suction cups 32 all belong to this surface.

In the example, the gripping device 10 comprises a pair of crosspieces 60 as described above, for example analogous or identical to each other.

For example, the crosspieces of the pair of crosspieces 60 are parallel to each other (as illustrated) or variously inclined, for example according to the mutual inclination of the longitudinal bars 20 by means of the hinged joint defined by each interconnecting body 70.

For example, a crosspiece 60 of the pair of crosspieces 60? connected, by means of two interconnecting bodies 70, respectively, to the pair of first longitudinal members 21, for example in correspondence with a central axial section of the same, axially interposed between the extremity? outer and the guide sleeve 23.

Another crosspiece 60 of the pair of crosspieces 60? connected, by means of two interconnecting bodies 70, respectively to the pair of second longitudinal members 22, for example in correspondence with a central axial section of the same, axially interposed between the extremity? outer and the guide sleeve 23.

Furthermore, it is not excluded that the hinge seat 45 and/or one or more? feet 50 can be defined at one end? free of one or both crosspieces 60, in a similar way to what was described above in correspondence with the end? free of a longitudinal bar 20.

Support trolley

The transport and/or installation device 1 also comprises a support carriage 80 configured to support (at least partially) the gripping device 10 (and the plate L being gripped) and to facilitate its movement (by an operator) by means of a mobile support on the ground.

The support carriage 80 ? fully illustrated, in particular, in figures 19 and 25.

The support carriage 80 ? configured to be arranged (axially) on an opposite side of the gripping device 10 with respect to a handle thereof, for example a handle 43 (of the longitudinal bar 20) or an auxiliary handle (of the cross member 60).

In practice, the support carriage 80 ? configured to define a lifting fulcrum for the gripping device 10, so that globally the transport and/or placing device 1 (that is, the whole support carriage 80 and gripping device 10) defines a lever of the second kind, in which is the resistive load? defined by the weight of the slab L gripped by the suction cups 32 ? ? axially interposed between the support carriage 80 ? or that lifting fulcrum ? and at least one handle of the gripping device 10, for example a handle 43 of the longitudinal bar? or a pair of handles 43 side by side with respect to the side by side direction B - or an auxiliary handle of the crosspiece 60, or a pair of auxiliary handles side by side with respect to a direction parallel to the longitudinal axis A of the longitudinal bar/s 20) .

The support carriage 80 comprises a support frame 81 (substantially rigid, i.e. non-deformable under the load defined by the gripping device 10 (and by the gripping plate L), or when stressed by the usual work loads to which it is intended in operation.

The support frame 81, how best will it look? described below with the aid of the detailed description of two embodiments, pu? be associated with the gripping device 10 (or with one or more of the elements that compose/constitute it), for example it can? be rigidly fixed to it (for example in a resolvable or permanent way) or defined integral (i.e. in a single body or welded) or constrained in a mobile or movable way (i.e. with the possibility of movement with respect to at least one degree of freedom?) and/or by means of a simple support constraint.

The support trolley 80 is also equipped with a mobile type of support on the ground, preferably a support wheel 82 (for example of the pivoting type), configured to allow and/or guide the movement of the support trolley 80 (and of the gripping device 10 supported by it, with the plate L being gripped).

The support trolley 80 has an overall height, from the point of support on the ground defined by the support wheel 82 to its top, maximum or at its point of attachment to the gripping device that ? substantially comparable (or equal) to the height of the gripping device 10 (or from the gripping plane of the same up to its opposite top?) and/or ? equal to or slightly greater than the distance between the gripping surface from the longitudinal bar/s 20 of the gripping device 10.

According to a preferred embodiment shown in figures 19? 23, the support carriage 80 (or the support frame 81 thereof) ? rotatably associated with the gripping device 10 around an axis of rotation R (horizontal) parallel to the gripping plane defined by at least one suction cup 32 of the gripping device 10.

For example, the axis of rotation R (when the support carriage 80 is fixed to one or both longitudinal bars 20) is? parallel to the flanking direction B.

However, it is not excluded that the axis of rotation R (when the support carriage 80 is fixed to one or both crosspieces 60) may be parallel to the longitudinal axis A of the longitudinal bars 20.

This axis of rotation R essentially defines the aforementioned lifting fulcrum for the transport and/or installation device 1.

For example, the support carriage 80 ? self-supporting, ie ? configured to support itself resting on the ground in a stable support configuration, so that the axis of rotation R, in this stable support configuration, is arranged parallel to the support surface (i.e. to the ground).

Preferably, the support carriage 80 comprises a plurality of of support wheels 82, each defining a respective point of support on the ground.

For example, the only support points on the ground of the support trolley 80 are defined by the support wheels 82.

In this embodiment, for example, the support frame 81 comprises a hinge pin 810 (rigid), which ? defined for example by at least one cylindrical bar (for example with a hollow or solid section), the central axis of which defines the aforementioned axis of rotation R.

For example, the hinge pin 810 has a length greater than or equal to the maximum distance that can be reached between two longitudinal bars 20 of the gripping device 10 (and/or the maximum width of a slab L allowed to be transported and/or laid with the device transport and/or installation 1).

Furthermore, the support frame 81 comprises at least one support assembly 811 of at least one support wheel 82, which ? configured to constrain the support wheel to the hinge pin.

The support unit 811 comprises an attachment flange 8110 (rigid) to which ? rotatably associated with at least one support wheel 82.

In the example illustrated, at least two support wheels 82 are associated with the attachment flange 8110 which are spaced apart from each other (along a direction ? horizontal ? orthogonal to the axis of rotation R).

For example, the two support wheels 82 are placed on opposite sides with respect to the axis of rotation R, for example equidistant from it, as will be better described below.

In the illustrated example, each support group 811 has (only) one pair of support wheels 82, however it cannot be excluded that the support group 811 may have more than one pair of support wheels. of two wheels (aligned), for example 3 in number, for example staggered/misaligned (i.e. at the vertices of an isosceles or, preferably, scalene) triangle or more than 3 in number.

Preferably, each jockey wheel 82 is of the pivoting type, i.e. ? associated in a pivoting way with respect to the attachment flange 8110 around its own pivot axis W1, which for example ? (and remains) substantially vertical (perpendicular to the ground) when the support wheel 82 is resting on the ground.

Basically, the gripping device 10 ? rotatably associated with the support frame 81 and this supports the support wheel/s 82, and the pivot axis W1 of each support wheel 82 remains orthogonal to the support and rolling surface of the same (the ground) even when the mutual inclination between the gripping device 10, or its gripping plane, with respect to the support and rolling surface thereof (the ground).

In other words, in this embodiment, the pivot axis W1 of the support (pivoting) wheels 82 is? tiltable (at will), or ? free to be oriented in various ways, with respect to the gripping plane defined by the gripping device 10. In particular, the pivot axis W1 of the support wheels 82 (pivoting) ?:

- parallel to the gripping plane of the gripping device 10 when the gripping device 10 ? placed vertically;

- orthogonal to the gripping plane of the gripping device 10 when the gripping device 10 ? placed horizontally; And

- ? variously inclined (not parallel) in any intermediate position between these two limit positions.

In particular, the pivot axes W1 of the (two) support wheels 82 supported by (the same) attachment flange 8110 are mutually parallel and are placed at an (equal) predetermined distance from each other which is not null (and greater than the radius of the support wheel support 82) from the rotation axis R (preferably, but not limitedly aligned with respect to an alignment direction orthogonal to the rotation axis R).

Each jockey wheel 82 ? pivotally associated with the attachment flange 8110 by means of a respective pivot pin which defines said pivot axis W1 of the respective support wheel 82, this pivot pin, or its end? lower (for example bifurcated at a fork) ? connected to a rotation pin Q1 which supports the support wheel 82 to support it in rotation (for example idle) around a rotation axis parallel and concentric to this rotation pin and orthogonal to the pivot axis W1.

The pivot axis W1 ? misaligned with respect to the rotation axis defined by the rotation pin.

The 810 hinge pin ? then fixed rigidly or in a resolvable way to the coupling flange 8110, for example in an intermediate area thereof (interposed between the two support wheels 82).

For example, the attachment flange 8110 includes an anchor seat 8111 configured to house and/or anchor to the hinge pin 810.

For example, the anchor location 8111 ? defined by a through opening (in the direction orthogonal to the pivot axis W1 (of the support wheels 82), within which the hinge pin 810 is able to be housed (inserted axially).

Furthermore, the point of contact with the ground of each jockey wheel 82 is placed at a predetermined distance from (the center of the anchoring seat 8111 and) the axis of rotation R (defined by the hinge pin 810).

This predetermined distance? (slightly) less than the predetermined distance defined between the? extremity? of the foot 50 (fixed to the anchoring bracket 41), i.e. the first foot and/or the second foot, and the through axis (i.e. the central axis of the upper closed portion) of the hinge seat 45.

Preferably, each jockey wheel 82 is associated in an adjustable way to the support frame 81, in particular with respect to the hinge pin 810, along a sliding direction parallel to a grip plane, preferably parallel to the axis of rotation R.

Preferably, each attachment flange 8110 (which supports the jockey wheel(s) 82), individually or in combination, is adjustably associated with the hinge pin 810, along a sliding direction parallel to the axis of rotation R.

In particular, each attachment flange 8110 ? configured to slide with respect to the hinge pin 810 along the direction parallel to the axis of rotation R and be locked in (any) axial position thereof.

For this purpose, the attachment flange 8110 comprises a locking unit, for example of the vice type, which is configured to lock the 8110 mounting flange to the 810 hinge pin.

The locking group, in the example, comprises a presser 83 able to enter the anchoring seat 8111 and equipped with an operating knob, which is? configured to clamp the hinge pin 810 against the walls of the anchoring seat 8111 (and be released to operate the axial sliding of the attachment flange 8110 along the hinge pin 810.

Preferably, the support frame 81 comprises at least one pair of (identical) support assemblies 811, for example as described above, spaced apart along a spacing direction parallel to the axis of rotation R.

Each of these 811 support groups ? adjustable as described above being able in fact to vary the reciprocal distance (as a function of the center distance between the longitudinal bars 20 and/or of the width of the slab L and of the desired stability of the transport and/or installation device 1).

The two support groups 811 are configured so as to be arranged (at will) in an intermediate area of the hinge pin 810, leaving the two opposite ends free. of the same.

The support carriage 80 ? adapted to be associated with the gripping device 10, for example fixed to it in a removable manner, preferably by defining a (simple) support constraint of the gripping device 10 on the support carriage 80. In greater detail, the support carriage 80 is constrained to the gripping device 10 by means of the engagement between the hinge pin 810 of the support carriage 80 in the hinge seat 45 of the gripping device 10, preferably in two coaxial hinge seats 45 of the gripping device 10.

In particular, the portions of extremity? (free) of the hinge pin 810 are configured to enter the respective hinge seat 45 (from the lower open portion thereof) and arrange themselves coaxially with the (upper closed portion of) the hinge seat 45 itself.

In this configuration, the upper closed portion of the hinge seat 45 is configured to embrace (to measure) a respective circumferential portion of the hinge pin 810 effectively defining a (simple) support constraint which allows and guides the reciprocal rotation between the gripping device 10 and the support carriage 80 around the axis of R rotation.

The weight of the gripping device 10 (and of the plate L being gripped) ? such as to keep the support trolley 80 and the gripping device 10 constrained to each other (during use, or during movement of the same with the support trolley 80 resting and moving on the support wheels 82).

It is not excluded that the hinge seat 45 may have a lower closing element capable of closing, for example in an elastic and/or snapping manner, the lower open portion, with the function of preventing the hinge pin 810 from slipping out of the hinge seat 45.

Finally, it is not excluded that in some applications, the support carriage 80 can be permanently fixed to the gripping device 10.

In this case, the hinge pin 810 could engage in a permanent (non-removable) hinge seat 45 made in the handle 40), which could then be detachable from the respective side member which defines the longitudinal bar 20 (or the crosspiece) and , for example, be replaced with a different handle when the use of the support trolley 80 is not necessary.

For example, the transport and/or laying device 1 comprises a braking unit, configured to brake, at least partially, the rolling of the support wheel 82 of the support trolley 80.

In a preferred and simplified version shown in the figures, the braking group ? defined by the foot 50 of the gripping device 10, for example one or both feet 50 associated with the anchoring bracket 41, and configured to rest on the ground in at least one determined reciprocal position between the support trolley 80 and the gripping device 10, or when the support carriage 80 ? resting on the ground by means of each support wheel 82 and the (gripping surface of the) gripping device 10 ? inclined to the horizontal, for example ? inclined at 45? (?15?) and/or ? essentially vertical.

It is not excluded, however, that in more embodiments? complex, the braking group may include a brake and/or a stop (for example that can be operated remotely, for example by means of a transmission lever and/or a cable - Bowden type - or wirelessly) configured to brake the rolling of the support wheel 82 and/or its revolution around the pivot axis W1.

In a simplified embodiment of the invention shown in FIGS. 24-27, the support carriage 80 is rigidly associated with the gripping device 10, i.e. without possibility? of reciprocal movements (ie without reciprocal degrees of freedom).

For example, the support carriage 80, in this case, can be rigidly fixed to at least one of one or more? support bars 20 or one or more? handles 40.

Furthermore, in this case, the support carriage 80, i.e. its support frame 81 does not have joints.

For example, the support trolley 80 comprises a rigid support frame 81, which supports a (single) support wheel 82, for example of the pivoting type. In the example, the transport and/or setting device 1 comprises a support trolley 80 for each longitudinal bar 20 (or for each crossbar 60).

For example, the only point of support on the ground of each support trolley 80 is? defined by the support wheel 82, which substantially defines the aforementioned lifting fulcrum for the transport and/or installation device 1.

In this embodiment, the support frame 81 comprises a support assembly 811 of at least one support wheel 82, which ? configured to support the jockey wheel itself.

The support unit 811 comprises an attachment flange 8110 (rigid) to which ? rotatably associated with at least one support wheel 82.

Preferably, the support wheel 82 is of the pivoting type, i.e. ? pivotally associated with the connection flange 8110 around its own pivot axis W1.

Preferably, the pivot axis W1 of the support wheel 82 is? inclined (ie not parallel) with respect to the gripping plane defined by the gripping device 10 (and fixed with respect to it), for example the pivot axis W1 ? inclined at an acute angle (external, i.e. facing away from the suction cups 32 which define the gripping plane itself).

Basically, the pivot axis W1 of the support wheel 82 varies its inclination as the reciprocal inclination between the gripping device 10, i.e. its gripping plane, with respect to the support and rolling surface of the support wheel 82 varies (the soil).

The support wheel 82 ? pivotally associated with the attachment flange 8110 by means of a respective pivot pin which defines said pivot axis W1 of the respective support wheel 82, this pivot pin, or its end? lower (for example bifurcated at a fork) ? connected to a rotation pin Q1 which supports the support wheel 82 to support it in rotation (for example idle) around a rotation axis parallel and concentric to this rotation pin Q1 and orthogonal to the pivot axis W1.

The pivot axis W1 ? misaligned with respect to the rotation axis defined by the rotation pin.

The 8110 connection flange? then rigidly fixed to the gripping device 10, or to an element that constitutes it.

For example, the 8110 connection flange can? be associated with the longitudinal bar 20 (or with the crosspiece 60), preferably but not limitedly, in an adjustable manner along the longitudinal axis A of the same.

In the example shown, the 8110 connection flange ? rigidly fixed to a handle 40, for example to an anchoring bracket 41 thereof.

For example, the 8110 ? defined integral (in a single body) or welded or in any case fixed, for example by means of bolts or other means, to the anchoring bracket 41, so as to extend it axially on the opposite side with respect to the longitudinal bar 20 to which ? anchored.

The possibility? for axial adjustment of the attachment flange 8110 along the longitudinal axis A of the longitudinal bar 20 (or of the cross member 60) to which ? fixed ? allowed by the possibility? for adjusting the axial position of the handle 40 described above.

Also in this simplified embodiment, the transport and/or laying device 1 can? comprise a braking unit, configured to brake, at least partially, the rolling of the support wheel 82 of the support carriage 80. In one possible version, the braking unit can? be defined by a foot, not shown, of the gripping device 10, which could derive below the anchoring bracket 41 so as to rest on the ground in at least one determined reciprocal position between the support carriage 80 and the gripping device 10, or when the support carriage 80 ? resting on the ground by means of the support wheel 82 and the (gripping surface of the) gripping device 10 ? inclined to the horizontal, for example ? inclined at 45? (?15?) and/or ? essentially vertical. It is not excluded, however, that in more embodiments? complex, the braking group may include a brake and/or a stop (for example that can be operated remotely, for example by means of a transmission lever and/or a cable - Bowden type - or wirelessly) configured to brake the rolling of the support wheel 82 and/or its revolution around the pivot axis W1.

A variant (not shown) of these embodiments could provide for the simplified structure of the second embodiment while maintaining the possibility of mutual inclination (the inclination?) between the gripping device 10 and the support carriage 80 (around an axis of rotation).

For example, if so, ? It is possible to provide that between the attachment flange 8110 and the (anchorage bracket 41 of the) handle 40, or between two separate portions of the attachment flange 8110, a hinge is provided having an axis of rotation R orthogonal to the longitudinal axis A of the longitudinal bar 20 (and parallel to the flanking direction B).

In this case, the pivot axis W1 of the support wheel 82 would be inclinable (at will), i.e. it would be free to be oriented in various ways, with respect to the gripping plane defined by the gripping device 10.

In particular, the pivot axis W1 of the support wheel 82 (pivoting) ?:

- parallel to the gripping plane of the gripping device 10 when the gripping device 10 ? placed vertically;

- orthogonal to the gripping plane of the gripping device 10 when the gripping device 10 ? placed horizontally; And

- ? variously inclined (not parallel) in any intermediate position between these two limit positions.

Operation

In the light of what has been described above, does the operation of the transport and/or laying device 1 ? the following.

For L slabs that are not excessively large or heavy ? It is also possible to act with a single operator to carry out the operations of picking up one slab L (at a time), transporting it and placing it on site, i.e. on a layer of glue.

To do what? ? It is possible, for example, to manually grip one or two grips 43 (which we will define as upper) and let the gripping device 10 on the side opposite the gripped upper grips 43 rest on the ground by means of the support carriage 80.

With the support trolley 80 resting on the ground by means of the support wheels 82 ? possible to move the transport and/or laying device 1 along any trajectory, guiding the same by gripping the upper handles 43 (opposite the support wheels 42), for example by placing the grip plane inclined with respect to the vertical and the horizontal at a comfortable angle for the operator. The gripping device 10 can? then be brought above a slab L to be picked up, for example lying on the ground or in any case arranged horizontally, with its upper surface visible and arranged above.

Preliminarily, the gripping device 10 ? configured to pick up this plate L, i.e. allow the pick up of the plate L.

To do this?, ? It is possible to arrange the suction cup gripping elements 30 with the suction cups 32 resting on the visible upper surface of the plate L and actuate them so that they create a vacuum and each one adheres stably to the plate L.

With the slab L gripped (below) by the gripping device 10, the gripping device 10 and the slab L are lifted, tilting it upwards and levering on the support carriage 80, or around the aforementioned lifting fulcrum. With the support trolley 80 resting on the ground by means of the support wheels 82 ? it is then possible to transport the gripped slab L along any permitted path by pushing and/or guiding the transport and/or laying device 1 by gripping the upper handles 43 (opposite the support wheels 42), for example by placing the gripping plane inclined to the vertical and horizontal at a comfortable angle for the operator.

When ? Once the slab L has been transported to the installation area used for it, one proceeds by laying it down with its lower installation surface adhered to the previously applied adhesive.

In the event that the installation takes place on a horizontal surface? can proceed as follows.

In practice, the operator, taking care to center the slab L in its laying area, progressively lowers the gripping device 10 by levering the support carriage 80.

In the preferred embodiment described above, during this operation the support trolley 80 remains stationary resting on the ground on the support wheels 82 (whose pivot axes W1 remain vertical) while the gripping device 10 is inclined up to a terminal position in which the gripping plane is horizontal and the slab L rests with its lower laying surface on the adhesive.

In the second embodiment described above, during this operation the support trolley 80 tilts upwards, partially lifting the support wheels 82 from the ground (although not completely) while the gripping device 10 is tilted up to a terminal position in which the gripping plane is horizontal and the slab L rests with its lower laying surface on the adhesive. Once the slab L has been placed on the glue ? it is possible to release the slab by releasing the suction cups 32 and move the transport and/or laying device 1 again for a new picking and laying operation.

If the installation takes place on a vertical surface ?, however, it is possible to proceed as follows.

In practice, the operator, taking care to center the slab L in its laying area, progressively lifts the gripping device 10 by levering on the support carriage 80.

During this lifting, the gripping device 10 rests (in certain critical inclinations) on the ground by means of one or two feet 50 (for example the second foot 50 described above).

This support allows the support carriage 80 to be braked from possible sliding due to the thrust (horizontal component moving away) exerted by the operator during lifting.

In the preferred embodiment described above, during this operation the support trolley 80 therefore remains stationary resting on the ground on the support wheels 82 (whose pivot axes W1 remain vertical) while the gripping device 10 is inclined (suspended or temporarily resting on the feet 50) up to a terminal position in which the gripping surface is vertical and the plate L.

In this final position the gripping device 10 rests on the feet 50 and/or can ? be rotated and/or further transported until the slab L rests with its lower laying surface on the adhesive.

Once the slab L has been placed on the glue ? it is possible to release the slab by releasing the suction cups 32 and move the transport and/or laying device 1 again for a new picking and laying operation.

The invention so? conceived ? susceptible to numerous modifications and variations, all of which are within the scope of the inventive concept.
