â € œSYSTEM FOR CLOSING A COMPARTMENT USING DRAGING SLIDING DOORS AND ASSEMBLY KIT FOR SAID SYSTEMâ €

DESCRIPTION

Technical field

The present invention relates to the field of closing doors for compartments inside buildings. More particularly, the invention relates to a system for closing a compartment by means of dragging sliding doors, preferably but not exclusively of the glass or crystal type.

The invention also includes a kit for assembling the aforementioned locking system.

State of the art

For many years now, systems for closing compartments have been known which involve the use of doors formed by sliding doors, parallel to themselves, from a packing position, in which the doors are all gathered on one side of the access opening to the compartment, laterally superimposed on each other, at a closed position, in which they develop to close the light, overlapping each other laterally for small portions of the edge.

In most of these systems, the doors are hung from sliding trolleys on guides fixed to the ceiling or to the wall, and the movement of the doors generally takes place by dragging. In practice, from the packing position, the user, by means of a handle, for example, drags what will be the terminal closing door of the compartment light; during translation, this leaf, by means of the abutment bodies positioned in correspondence with the upper carriages, comes into contact with the counter-abutment bodies present on the carriages of the immediately contiguous leaf, thus dragging it towards the closing position. If there are three doors, the second moving door will be equipped with abutment bodies and the third door will be equipped with counter-abutment bodies, so that during the movement of the second wing, the third wing is also moved. The opening movement of the compartment, or rather the movement of the doors towards the packing position, takes place in a substantially opposite way, again by dragging.

These systems, although known for some time, have different drawbacks. A first drawback is linked, for example, to the size of the doors when they are in the packing position. In this position, in fact, the abutment bodies and the counter-abutment bodies are interspersed on the carriages, above the doors, with a configuration that forces the external edges of the doors, or the edges that look towards the closed position, to be offset between them, with an evident increase in the overall dimensions of the packing position and reduction of the light in the compartment, which is greater the greater the number of sliding doors used.

Furthermore, it may happen that foreign elements enter the spaces above the doors, between the guides, the trolleys and the bearing bodies and the counterblocking bodies, blocking the movement of the doors or making it noisy; in these cases it is necessary to take a ladder, remove the masking protections of the guides and carriages and remove the extraneous elements.

Furthermore, in the known systems described above, the doors tend to oscillate around an axis substantially corresponding to the sliding plane of the carriages on the guides. Sometimes, to avoid this situation, lower guides are incorporated in the floor for guide elements associated with the lower edge of the doors, thus binding them to the floor, avoiding oscillation; it goes without saying that the use of a guide incorporated in the floor leads to problems of both installation and maintenance, linked to the possibility that objects slip into the guide itself.

Last but not least, in the systems described above, often the doors, due to assembly imperfections or small variations in the structure to which they are associated, can lose their correct horizontal arrangement, with the result that the doors tend to move towards the packing or closing position. , even when not required.

Purpose and summary of the invention

The main purpose of the present invention is to solve the aforementioned drawbacks, realizing a system for closing a compartment by means of dragging sliding doors, which is constructively simple and an assembly kit for said system.

Another important object of the present invention is to provide a system for closing a compartment by means of dragging sliding doors, which is reliable in operation.

Another important object of the present invention is to provide a system for closing a compartment by means of dragging sliding doors, which is simple to assemble.

Another important object of the present invention is to provide a system for closing a compartment by means of dragging sliding doors, which avoids or reduces the possibility of the doors swinging during movement.

Not the least important object of the present invention is to provide a system for closing a compartment by means of dragging sliding doors, which allows a stable positioning of the doors in its operating positions.

These and other purposes, which will be clearer hereinafter, are achieved with a system for closing a compartment by means of sliding sliding doors as per claim 1 below, and with an assembly kit as per claim 17.

The invention relates in particular to sliding doors without a perimeter frame in which dragging devices could be masked. The invention refers to a system that provides elements or kits that must be applied substantially on the external surface of the doors. It goes without saying that these elements or kits could also be applied to the external surface of doors with perimeter frame.

According to a first aspect, therefore, the system for closing a compartment by means of dragging sliding doors, according to the invention, comprising: - a series of at least two doors sliding parallel to each other from a first packing / opening position in which they are substantially superimposed on the front, to a second closing position of a compartment in which the doors are removed from each other, and vice versa; this series includes at least a first leaf and a second leaf, with said first leaf, for the terminal closure of the compartment, which precedes the second leaf during movement,

- longitudinal sliding means for the doors, arranged above said doors, from which the doors are hung,

- abutment elements for the dragging of contiguous leaves, fixed near the two edges, external and internal, at least of the first terminal closing leaf,

- at least one guiding and dragging unit fixed near the outer edge of at least said second door, comprising

or a sliding guide portion for the lower edge of said first terminal wing, e

or counter-abutment portions for said abutment elements of said terminal wing,

therefore, in the movement from the packing / opening position to the closing position, the abutment element associated with the internal edge of the first terminal leaf that precedes the second leaf in the movement, collides against a first said counter-abutment portion associated with the second leaf that follows, dragging this second leaf with it, while, in the movement from the closing position to the packing / opening position, the abutment element associated with the external edge of the first leaf impacts against the second counter-counter portion of the guiding and dragging the second door, dragging it with it.

According to preferred embodiments, the system for closing a compartment according to the invention comprises at least three doors; of said at least three doors there are, a last door able to close the compartment on the opposite side of this with respect to the first door, and a penultimate door that precedes the last door; said abutment elements are associated near the inner and outer edges of the penultimate door for the dragging of contiguous leaves; at least one said guiding and dragging unit fixed near the outer edge of the last leaf is associated with said last leaf, which comprises a sliding guide portion for the lower edge of the penultimate leaf, and counter-abutment portions for elements check of the penultimate door; the system is such that in the movement from the packing / opening position to the closing position, the reference element associated with the internal edge of the penultimate door that precedes the last door in the movement, collides with a first portion of the counter - striker of the guiding and dragging unit associated with the last leaf that follows, dragging with it said last leaf, while, in the movement from the closing position to the packing / opening position, the striker element associated with the external edge of the penultimate terminal leaf strikes against the second counter-striker portion of the guide and dragging unit associated with the last leaf, dragging it with it.

It is possible to say, according to preferred embodiments, that the closing system of a compartment according to the invention, which includes at least three doors, requires that there is at least one intermediate door between the first door and the last door designed to close the compartment; said abutment elements are associated near the inner and outer edges of said intermediate door for the dragging of contiguous leaves; associated with the external edge of said intermediate door is a said guiding and dragging unit, comprising a sliding guide portion for the lower edge of the contiguous door that precedes it, and counter-striker portions for striking elements of the contiguous door which precedes, so that in the movement from the packing / opening position to the closing position, a striker element associated with the internal edge of the door that precedes said intermediate door, strikes against a first said counter-striker portion associated with said intermediate door which follows, dragging the intermediate door with it, while, in the movement from the closing position to the packing / opening position, the check element associated with the external edge of the door that precedes the intermediate door against the second counter-abutment portion of the guiding and dragging unit of said intermediate leaf, dragging it with it.

In the following description, the intermediate door can also be understood as the last door, that is, a door after the first door; therefore, in a two-door system with an intermediate door, the second and last door of the system can also be understood.

In general, as will become clearer later and according to the typical scheme of sliding door systems, each door, with the exception of the last door (that is, the one opposite the first door that closes the opening of the compartment with respect to any other doors intermediate), drags a respective contiguous door both in the closing movement of the compartment and in the packing / opening movement (in the closing movement the moving contiguous door is pulled, in the opening movement the moving contiguous door is pushed) .

Preferably, the abutment elements for dragging contiguous leaves, and the at least one guiding and dragging unit fixed near the outer edge of at least said second leaf, or the intermediate leaf, are fixed near the lower edge of the respective doors. Purely by way of example, the abutment elements for the dragging of contiguous leaves, and the at least one guiding and dragging unit can be designed to be fixed at a distance from the lower edge between about 1/20 and 1/200 the height of the door to which they are fixed. It must be understood that the distance from the lower edge is fixed and cannot be varied during use; the interval indicated above is an interval relating to the design phase of the system.

Preferably, the outer edges of the doors are substantially aligned when the doors are in said packing position.

Advantageously, the system can include a guide to be fixed to the floor in which the last door of the series of doors is slidably arranged, ie the last door to be dragged during the opening movement.

According to preferred embodiments, the guiding and dragging unit comprises a sandwich locking portion at the outer edge of the intermediate door; on one side of the locking portion develops an appendix forming a said abutment element; on the side of the locking portion, opposite to said appendix with respect to the door, a pair of seats open in directions is defined at a distance from the lower edge of the door substantially corresponding to the distance of the appendix from the lower edge opposite towards the opening or closing direction of the doors, of reception for a respective said appendix, in which respective counter-striker portions are defined for the striker elements of the door that precedes the movement; this guiding and dragging unit includes, on the same side of the leaf in which the seats are present, the aforementioned sliding guide portion for the leaf that precedes the movement. Conveniently, the locking portion can have a distance from the lower edge of the leaf at least equal to or greater than the depth of said guide portion; said guide portion is lower than the seats and is laterally projecting from these.

Preferably, in this guiding and dragging assembly, the seats, the guiding portion and at least part of the locking portion are made in a single piece.

Preferably, the abutment elements for dragging contiguous leaves, fixed near the two edges, external and internal, of the terminal closing leaf and of the internal edge of the at least one intermediate leaf, comprise a said appendix suitable for associate with the counter-abutment portions of a relative guiding and dragging group of the contiguous intermediate leaf.

Conveniently, two strike groups are associated with the first leaf, or the terminal closing leaf, each comprising an abutment element; these abutment groups comprise respective portions of sandwich locking to the door; preferably said locking portions comprise a plate and a counter-plate arranged on opposite sides of said wing, and a screw for connecting said plate and counter-plate passing through said wing.

Preferably, at least one intermediate leaf is associated, on opposite edges, with a said guiding and dragging unit fixed in proximity to the outer edge and an abutment assembly comprising at least one said abutment element; the striker unit includes respective portions of sandwich locking to the door; preferably the locking portions comprise a plate and a counter-plate arranged on opposite sides of said plate, and a screw for connecting said plate and counter-plate passing through the door.

Preferably, there is a reversible coupling between the abutment element and the relative counter-abutment portion; preferably, this reversible coupling is of the type by elastic deformation.

Conveniently, the aforementioned appendix is surrounded by an elastic ring, preferably made of rubber or the like. Advantageously, the seat in which the appendix must meet may have a concave C-shaped conformation of such dimensions as to force the elastic ring to deform temporarily due to crushing during the entry phase of the appendix into said seat; this seat forces the appendix into position when it is inserted inside it; the phase of exit of the appendix from the seat is necessary with a thrust such as to overcome the elastic deformation of the ring to exit the seat.

According to another aspect, the invention relates to a kit for the assembly of a system for closing a compartment by means of sliding sliding doors according to one or more of the previous embodiments, comprising at least - the aforementioned abutment elements for dragging of contiguous doors, to be fixed near the two edges, external and internal, at least of said terminal closing door and / or of an intermediate door,

- said at least one guiding and dragging unit to be fixed near the outer edge of said at least one intermediate leaf.

Preferably, the kit includes, for a system that includes a number of â € œnâ € sliding doors, â € œn-1â € striker units to be fixed near the internal edge of the doors, with the exception of the last â € œnâ € , an abutment group to be fixed to the outer edge of the first door (for terminal closure), and â € œn-1â € guiding and dragging groups to be fixed to the external edge of the doors with the exception of the first door; preferably the system also includes a ground guide for the last â € œnâ € leaf.

Figures 18 to 21 show four different configurations of systems according to the invention, in which different packing niches are visible, and versions with different number of doors.

Detailed description of an embodiment of the invention With reference to the aforementioned figures, a system for closing a compartment by means of dragging sliding doors is generally indicated with the number 10.

In this example, the system 10 foresees a series of three leaves 11, also indicated respectively with 11â € ™, 11â € ™ â € ™, and 11â € ™ â € ™ â € ™; in the following, elements associated with a specific door will also be indicated with a corresponding number of quotes; when characteristics associated with a door are indicated without apex, it means that they can concern all the doors, unless the context indicates otherwise. These doors 11 slide parallel to themselves from a first position, for packing, as in figures 1, 2, 3 and 4, to a second position, for closing the opening for accessing a compartment, as in figure 8; the access light to the compartment is not explicitly indicated in the figures; more generally it will be indicated below â € œclosing position of the compartmentâ €; the jamb against which the closing doors meet is indicated with the letter S in figures 7, 8 and 9.

The doors 11 are made for example of plates, preferably flat and preferably of equal width, height and thickness. By width we mean the dimension orthogonal to the vertical development of the slab when positioned upright, hereinafter referred to as â € œheightâ €. In the following, the term slab or the term door will sometimes be used to indicate the same object.

In this example, the plates are made of glass or crystal. It goes without saying that in other examples, such slabs can be in any other material, such as wood, marble, resin, plastic, combination of these, etc.

Advantageously, in preferred embodiments, in the packing position, the plates are superimposed on the front, with the external edges, indicated by 12A, which are substantially aligned, as clearly visible in figure 3 and in figure 4. The alignment therefore takes place according to a line L orthogonal to the plane of the slabs or to the direction of their movement. In the following, with internal edge, indicated with 12B, we mean the edge of the slabs, i.e. the face of the slab relative to the thickness, facing the packing position, i.e. the edge of the slabs which during the movement from the closing position to the the packing position reaches the packing position first. The external edge 12A therefore refers to the opposite edge of the plates, that is the edge which faces the direction of closure of the compartment.

Preferably, the doors, when they are in the packing position, are contained inside a niche 13. In this example, the niche 13 is formed by a single masking wall 13A, for example formed by a fixed static plate ceiling and floor by means of a frame 13B. The niche 13 is therefore open on the side opposite the static plate 13A with respect to the doors 11, and on the side relating to the area where the door 11 comes out of the niche itself.

For example, the area of exit of the sheets 11 from the niche 13 coincides approximately with the alignment plane of the external edges 12A of the sheets, which in turn coincide with the external edge 13C of the static sheet 13A, as shown in figure 4. In other forms The external edges 12A of the slabs can be internal to the niche 13, or external to the niche.

In other embodiments, this niche can be closed on both sides of the doors, for example by two static plates, as for example in figure 19. In other examples, the niche 13 can be made close to a structural element, a wall in masonry (as for example in figure 21), a plasterboard wall, etc.,.

Each leaf is supported by at least one trolley 14 (more preferably at least two trolleys), arranged slidingly on a respective aisle 15, for example fixed to a ceiling 16 opposite a floor 17. The leaves 11 are therefore hung on the trolleys 14. Aisles 15 and carriages 14 are in practice longitudinal sliding means for the leaves 11.

In the example of figure 1, the system foresees a series of three leaves 11. The system, in a per se known way, foresees that from the packing position, a first door 11â € ™, corresponding to what will be the ™ closing door at the end of the compartment, is moved towards the closing position. This first door 11â € ™ translates (figure 5), and during its translation, when it is extended for most of its width outside the niche 13, by means of the meeting means described further on, â € œcatchesâ € a second door 11â € ™ â € ™, contiguous to it, dragging it with you (figure 6).

Similarly, the second door 11â € ™ â € ™, which is an intermediate door in the series of doors that make up the system, in its translation (figure 6), when it is extended for most of its width beyond outside the niche 13, by means of meeting means, he hooks the third intermediate door 11â € ™ â € ™ â € ™, dragging it with him (figure 7). When the third door 11â € ™ â € ™ â € ™ is also withdrawn for most of its width outside the niche 13, the compartment is closed, ie the closed position is reached (figure 8). As already said, in the following, elements associated with the first leaf will also be indicated with a superscript, the elements associated with the second leaf with a double apex, and the elements associated with the third leaf with a triple apex.

In the following, the second intermediate leaf 11â € ™ â € ™ is also referred to as the intermediate leaf which follows (or following) the terminal closing leaf 11â € ™ during movement, or the intermediate leaf which precedes the third intermediate leaf 11 ' â € ™ â € ™ during movement. The first leaf 11â € ™ therefore precedes the second intermediate leaf 11â € ™ â € ™. Similarly, during the closing movement, the third intermediate leaf 11â € ™ â € ™ â € ™ is also defined as the leaf following (or following) the second intermediate leaf. In practice, the door that is dragged is a door following the door that it drags, while the door that drags is the door that precedes the door that it drags.

The aforementioned meeting means, which allow a leaf to be dragged by the leaf that precedes it during the closing movement, provide for abutment elements 18R-19R for dragging contiguous leaves, better described below, fixed near the two edges, external 12A and internal 12B, of each door, with the exception of the internal edge 12Bâ € ™ â € ™ â € ™ of the last door, that is the third intermediate door 11â € ™ â € ™ , as clearly visible in figures 4 to 9.

In addition, for the second intermediate leaf 11â € ™ â € ™ and the third intermediate leaf 11â € ™ â € ™ there are also respective guiding and dragging groups, numbered respectively with 20â € ™ â € ™ and 20â € ™ â € ™ â € ™, fixed near the respective outer edges 12A. Each group 20 (i.e. 20â € ™ â € ™ and 20â € ™ â € ™ â € ™) includes a sliding guide portion 21 for the lower edge 12C of the door that precedes in the closing movement of the compartment (door that precedes : or the first closing wing 11â € ™ in the case of group 20â € ™ â € ™, or the second intermediate door 11â € ™ â € ™ in the case of group 20â € ™ â € ™). In addition, each group 20 also includes counter-abutment portions 22 (clearly visible in figures 13 and 17) for the abutment elements 18R and 19R associated with the doors that precede the door equipped with the respective group 20 in the closing movement (as it will be clearer forward, the striker element 19R acts in drag during the closing movement, while the striker element 18R acts during the opening movement).

In practice, in the movement from the packing / opening position to the closing one, the striker element 19Râ € ™ associated with the internal edge 12Bâ € ™ of the closing terminal door 11â € ™ which precedes the second intermediate door 11â € ™ â € ™ (intermediate leaf 20â € ™ â € ™ to whose external edge 12Aâ € ™ â € ™ the guide and dragging unit 20â € ™ â € ™ is fixed) comes to abut against the counter-striker portion 22 (better described later) of group 20â € ™ â € ™, dragging it with it, and then dragging with it the whole second intermediate leaf 11 '' (figures 5, 6 and 16). As the second intermediate door 11â € ™ â € ™ slides, the respective striker element 19Râ € ™ â € ™ associated with the internal edge 12Bâ € ™ â € ™ of this door meets the counter-striker portion 22 of group 20â € ™ â € ™ â € ™ fixed to the external edge 12Aâ € ™ â € ™ â € ™ of the third intermediate leaf 11â € ™ â € ™ â € ™, dragging the latter with it until the position of closure (figures 6, 7, 8 and 17).

On the contrary, in the movement from the closing position to the packing / opening position, the abutment elements 18R associated with the outer edges of the preceding doors, collide in sequence against the second counter-striker portions 22 of the following doors, dragging them with them. intermediate doors that follow towards the opening.

Conveniently, the system 10 can provide a guide 23, to be fixed to the floor 17, in which the last door of the series is slidably arranged (i.e. the last door to be dragged into the closed position during the closing movement) , that is, in this example the third intermediate door 11â € ™ â € ™ â € ™ of said series of doors. Preferably, said guide 23 is shorter in length than the width of said last door 11â € ™ â € ™ â € ™. Again, preferably this guide 23 is completely contained in the niche 13, for example aligned with its outer end 23A at the outer edge 13C of the static plate 13A (or at the edges 12A of the doors 11). In this example, the guide 23 has a U-shaped transverse profile.

Preferably, the guiding and dragging unit 20 (see for example Figures 10, 11, 12 and 13, in which the plate 11 is not visible) comprises a sandwich locking portion 24 to the outer edge 12A of the door intermediate plate 11 to which it is fixed, formed by a plate 24A and a counter-plate 24B arranged on opposite sides of the plate 11, and a screw 24C for connecting the plate and the counter-plate, passing through the plate itself. The plate 24A has a shaped part 24D adapted to abut against the outer edge 12A of the plate 11, which also allows to maintain the correct orientation of the unit 20 with respect to both edges 12A and 12C.

Conveniently, in preferred embodiments, the guiding and dragging unit 20 also includes an aforementioned abutment element 18R relative to the outer edge 12A. For example, on one side of the sandwich locking portion 24 an appendage develops which forms this abutment element 18R. For example, this appendix, also numbered 18R for simplicity, develops from the counter-plate 24B.

Preferably, on the side of the locking portion 24, opposite to the appendix 18R with respect to the leaf 11, it is defined, at a distance F from the lower edge 12C of the leaf 11 substantially corresponding to the distance of the appendix 24 from the the same lower edge 12C, a pair of seats 25, open in opposite directions towards the opening or closing direction of the doors, for receiving a respective appendix 18R or 19R. At the bottom of these seats 25 respective counter-abutment portions 22 are defined for the abutment elements 18R, 19R of the door that precedes in the closing movement.

Conveniently, the guiding and dragging unit 20 includes, on the same side of the leaf 11 in which the seats 25 are present, also the sliding guide portion 21 for the leaf that precedes the movement, as described above.

Preferably, in the guiding and dragging assembly 20, the seats 25, the guiding portion 21 and at least part of said locking portion, for example, the plate 24A, are made in a single piece.

With particular reference to Figure 2, it should be noted that, preferably, the locking portion 24 has a distance D (for example measured from the lowest point of the counterplate 24B) from the lower edge 12C of the leaf 11 at least equal to or greater than the depth P of the guide portion (for example measured vertically from the bottom of the guide portion to the horizontal projection of the lowest point of the same point of the block portion 24 from which the distance D from the lower edge 12C was measured).

The guide portion 21 is lower than the seats 25 and preferably projects laterally therefrom (in practice it projects laterally and downwards). Said guide portion 21 has, for example, a guide cavity 21A with a U-shaped cross section.

According to the above, it is clear that there are two guiding and dragging groups 20 '' and 20 '', fixed near the respective outer edges 12A '' and 12A '' Of the second intermediate leaf 11 'and the third intermediate leaf 11' (last leaf of the series to be dragged towards the closing position). It should be noted that, in the figures, an appendix 18Râ € ™ â € ™ â € ™ is shown, that is, protruding from the third driving and dragging group 20â € ™ â € ™ â € ™, which has no practical function , not having to encounter anything, but has a purely aesthetic function and industrial convenience (as well as having the practical utility of serving as a threaded seat to screw the screw 24C and lock the group 20).

In the event that the number of leaves are two (as in figure 18), there will be a single guide and dragging unit 20â € ™ â € ™, on the second intermediate door 11â € ™ â € ™ (the same numbering is maintained of the previous case); also in this case the appendix 18Râ € ™ â € ™ has only an aesthetic function and industrial convenience.

In the case of more than three leaves, for example five leaves, as in figure 20., there are four guiding and dragging groups 20â € ™ â € ™, 20â € ™ â € ™, 20 <IV> and 20 <V>, for the respective four leaves 11â € ™ â € ™, 11â € ™ â € ™ â € ™, 11 <IV> and 11 <V> (last door); also in this case the appendix 18R <V> has only an aesthetic function and industrial convenience (in addition to having, as already said, also the practical utility of serving as a threaded seat to screw the screw 24C and lock the group 20 ).

Generally speaking, it is possible to say that given a number n of doors (with a minimum of m or two sliding leaves), there will be n-1 guiding and dragging groups 20.

The striker elements 19R are preferably in the form of appendages which protrude laterally from striker groups 26 fixed at the internal edges 12B of the doors (with the exception of the last door to be dragged, in the case of three doors, the third intermediate door 11â € ™ â € ™ â € ™). These appendices, which are also numbered 19R for simplicity, are preferably identical to the appendices 18R. Each abutment group 26 (see for example Figures 14 and 15, in which the plate 11 is not shown) has a further sandwich locking portion 24bis which comprises, similarly to the case of the guiding and dragging groups 20, to for example, a further plate 24a and a further counter-plate 24b arranged on opposite sides of the respective plate, and a further screw 24c for connecting said plate and counter-plate passing through said plate. Also in this case, the further plate 24a has a further shaped part 24d adapted to abut against the internal edge 12A of the plate 11. The appendix 19R protrudes from the further counterplate 24b.

Similarly, only for the first leaf 11â € ™, there is an additional striker unit 26bis, similar to the striker unit 26â € ™, arranged near the outer edge 12Aâ € ™ of the door, substantially at the same height and position as the feedback group 26â € ™.

Now, as mentioned, the abutment elements 18R and 19R are adapted to abut against the counter-abutment portions 22 of the guide and dragging units 20. The appendages which form the abutment elements 18R and 19R are preferably cylindrical symmetry and are surrounded by an elastic ring 27, for example of the o-ring type, made of rubber or other similar material. When the appendages 18R and 19R enter the seats 25 and meet against the counterblock portions 22, there is suitably a reversible coupling between them, so that there is a certain degree of tightness between the abutment appendix and the relative seat 25. reversible occurs thanks to the elastic deformation of the ring.

Conveniently, each opposing seat 25 has a concave shape, for example C-shaped, of such dimensions as to force the elastic ring 27 to deform temporarily by crushing during the entry step of the appendix into the seat; when the appendix is inserted inside the seat, its shape forces the appendix itself to remain in position; the phase of exit of the appendix from the seat takes place simply with a push, in the direction of the opening of the seat, in order to overcome the elastic deformation of the ring.

Note how in figures 13 and 17, the two opposing seats 25 have a backless C-shape, ie the seat, on the top and bottom, has two opposing cusps which define the counter-abutment portions 22. The space between the two cusps would correspond to the back part of the seat at â € œCâ €. According to another point of view, each seat is formed by two opposing concave portions 25a, defined on the sky and on the bottom, facing each other, one side of which is made by the cusps defining the counter-abutment portions 22.

As said, the outer edges 12A are preferably aligned with each other along L. In other embodiments, the outer edges 12A may not be aligned. For example, in some cases, it may be useful to attach a handle to the first door 11â € ™ and therefore there is the need for the external edge of the first door to protrude a little with respect to the external edges of the other doors (possibly aligned with each other); In this case it will be necessary to fix the striker element 18Râ € ™ at a greater distance from the external edge 12Aâ € ™ than the distance relative to the alignment case (i.e. a greater distance than the distance of the relative seat 25 from the external edge 12Aâ € ™ â € ™ of the second door 11â € ™ â € ™).

The system works as follows. Reference is made to the packing / closing position, in which all the doors are aligned with their outer edge 12A on line L (figure 4). The first leaf 11â € ™ has the appendix 18Râ € ™ of the striker group 26bis inserted in the seat 25 of the guide and dragging group 20â € ™ â € ™ fixed to the second leaf 11â € ™ â € ™; similarly, the second leaf 11â € ™ â € ™ has the appendix 18Râ € ™ â € ™ protruding from its driving and dragging unit 20â € ™ â € ™ inserted in the seat 25 of the driving and dragging unit 20â € ™ € ™ â € ™ fixed to the third leaf 11â € ™ â € ™. The lower edge 12Câ € ™ of the first leaf 11â € ™ is inserted in the guide portion 21â € ™ â € ™ of the driving and dragging unit 20â € ™ fixed to the second leaf 11, thus as The lower edge 12Câ € ™ â € ™ of the second leaf 11â € ™ â € ™ is inserted in the guide portion 21â € ™ â € ™ â € ™ of the guide and dragging unit 20â € ™ â € ™ fixed to the third door 11â € ™ â € ™ â € ™. The lower edge 12Câ € ™ â € ™ â € ™ of the third and last leaf 11â € ™ â € ™ â € ™ is inserted in the ground guide 23.

The user begins to push the first leaf 11â € ™ towards the closing position, overcoming the slight resistance due to elastic deformation (viscoelastic or similar) of the ring 27 on the seat 25 of the driving and dragging unit 20â € ™ â € ™, so that the appendix 18Râ € ™ of the striker group 26bis comes out of the seat 25. The leaf 11â € ™ thus slides with its portion of the lower edge 12Câ € ™ (figure 5) within the guide portion 21â € ™ â € ™ of the drive and drag unit 20â € ™ â € ™. At a certain point, the appendix 19Râ € ™ of the striker group 26â € ™ of the first leaf 11â € ™ enters the seat 25 of the guide and dragging group 20â € ™ â € ™ of the second leaf 11â € ™ â € ™ , deforming its own ring 27 and striking it against the counter-striker portion 22 of the guide and dragging unit 20â € ™ â € ™.

Continuing the translation of the first leaf 11â € ™, also the second leaf 11â € ™ â € ™ begins to translate towards the closed position (figure 6). The second leaf 11â € ™ â € ™ slides with its portion of the lower edge 12Câ € ™ â € ™ within the guide portion 21â € ™ â € ™ â € ™ of the guide and dragging unit 20â € ™ â € ™ € ™.

At a certain point, the appendix 19Râ € ™ â € ™ of the guide and dragging group 20 "of the second leaf 11" enters the seat 25 of the guiding and dragging group 20 " Of the third leaf 11â € ™ â € ™ â € ™, deforming its ring 27 and finding against the counter-striker portion 22 of the guide and dragging unit 20â € ™ â € ™ â € ™. Continuing the translation of the first leaf 11â € ™, also the third leaf 11â € ™ â € ™ â € ™ begins to translate towards the closed position (figure 7). The third leaf 11â € ™ â € ™ â € ™ slides with its portion of the lower edge 12Câ € ™ â € ™ â € ™ within the guide on the ground 23. When the outer edge 12A of the first leaf 11 reaches jamb S, the closed position of the compartment has been reached. In this position, the third leaf 11â € ™ â € ™ â € ™ is still inside the ground guide 23 (figure 8).

From the closed position, the user can push the first leaf 11â € ™ towards the packing position; in doing so, the slight resistance of the seat 25 of the second guiding and dragging group 20â € ™ â € ™ on the ring 27 of the striker element 19Râ € ™ of the striker group 26â € ™ wins. At this point the first leaf 11â € ™ slides into the guide portion 21â € ™ â € ™ of the guide and dragging unit 20â € ™ â € ™ of the second leaf 11 (still stationary) (figure 9) until when the striker element 18Râ € ™ of the striker group 16bis enters the seat 25 of the second guiding and dragging group 20 ', striking against the counter-striker portion 22 and thus bringing in translation also the second door 11â € ™ â € ™. The movement continues in the same way until all the doors are brought back into the niche 13.

From a practical point of view, it may happen that, if 18R-19R striker elements are used that hook / couple reversibly to the counter-striker portions (for example appendages with rings 27 coupled to seats 25), the The order in which the doors detach from each other, both in the closing movement of the compartment and in the opening / packing movement, and casual (in practice depending on the force necessary for the doors to `` detach '' From each other).

For example, in the case with three doors, it may happen that when opening the compartment, the user drags the first door 11â € ™ and this, instead of immediately detaching itself from the second door 11â € ™ â € ™ translating with respect to this, brings the same second leaf immediately in motion (in practice, the first and second leaf still move integrally with the two non-overlapping leaves). At this point it may happen that the second door immediately separates from the third door 11â € ™ â € ™ â € ™, with the first antasecond door complex moving relative to the third door (with which then the movement of the doors follows the one already described above, i.e. the second door that is found on the third door, aligning with this in the packing position and the first door that begins to translate with respect to the second door, returning within the niche), or that the second door does not detach from the third leaf, while the first leaf detaches from the second, moving relative to the second-third leaf assembly, as in the case described above. The same can be said in the case of the closing movement of the compartment, i.e. it may happen, for example, that when moving the first door, the second door immediately moves together with it (i.e. overlapping with the external edges aligned), subsequently dragging the third door. The door â € œreleaseâ € combinations can be multiple. In practice, the order of â € œ detachmentâ € of the doors can be random, obviously all following the movement of the first door.

In general, there may be a limit switch stop (not shown in the figures) for the last leaf of the system, when it is arranged to close, together with the other leaves, the compartment, preferably arranged on the upper lane, in which the relative trolley slides. This stop identifies the closing position of the last leaf, beyond which it can no longer advance. An end-of-stroke stop (not shown in the figures) can also conveniently be present in the packing position of the last door, so that it does not advance more than this position within the niche 13. More generally, there may be limit switch stops in the relative closing and packing positions for each door of the system.

The invention also relates to a kit for assembling a system for closing a compartment by means of sliding sliding doors as to one or more of the possible embodiments hypothesized above, which includes at least the abutment elements 18R, 19R, for the dragging of contiguous leaves 11, to be fixed near the two edges 12A and 12B, external and internal, at least of the terminal closing leaf 11â € ™ and / or of an intermediate leaf 11â € ™ and 11â € ™ € ™.

Preferably, the kit includes, for a system that includes a number of â € œnâ € sliding doors, â € œn-1â € striker units 26 to be fixed near the internal edge 12B of the doors, with the exception of the last door â € œnâ €, a striker unit 26bis to be fixed to the external edge 12Aâ € ™ of the terminal closing leaf 11â € ™, and â € œn-1â € guide and dragging units 20 to be fixed to the external edge 12A of the leaves except of the first door 11â € ™; preferably the system also provides a ground guide 23 for the last leaf 11 <n>.

The system and the relative kit thus described, achieves the aims set for it. In fact, thanks to the check elements placed in the lower part of the doors, it is possible to keep the external edges of the doors aligned with each other when in the packing position. Furthermore, with this configuration, the risks of system malfunction are very low; as well as the maintenance of the system is facilitated.

Furthermore, the doors are well guided during their travel, with the elimination of the effect of oscillation around the upper aisle in which the trolleys to which the doors are hung slide slide.

Last but not least, the matching method of the striker elements and the counter-striker portions makes it possible to guarantee the stability of the positions of the doors even in the face of small inaccuracies in the horizontality of the sliding system of the doors, guaranteeing at the same time greater silence in movement. of the doors.

It is understood that what has been illustrated represents only possible non-limiting embodiments of the invention, which may vary in forms and arrangements without departing from the scope of the concept underlying the invention. The possible presence of reference numbers in the attached claims has the sole purpose of facilitating the reading in the light of the above description and the attached drawings and does not in any way limit the scope of protection.
