DESCRIPTION

EXTENSIBLE STRUT ATTRACABLE BETWEEN TWO PARALLEL PLANS AND KIT FOR

ERECTION OF WALLS

Field of technique

The present invention concerns the field of extensible supports mountable to compression between two parallel planes and equipped with an elastic element, and a kit for the erection of walls. Said strut provides an axial thrust against said two parallel planes thanks to the elastic element, obtaining an active propping, and the extensible being allows to place and remove said strut without difficulty or work, besides regulating the thrust exerted by said elastic element, being able to be used also as a structure for a dry-installed lining, by removable fixing of lining plates on tubular elements, especially to fixing devices in the form of an elastic gripper capable of being anchored to a tubular element and provided with coupling configurations suitable for anchoring of one or several coating plates.

State of the art

It is known to use extensible struts provided with an elastic element to be docked between two parallel planes.

For example, document DE202004016792U discloses struts of this type, which integrate at their upper end an elastic element, as well as a threaded element to expand the strut, increasing the force exerted by it on the floor and the ceiling, which are used as support to support divisions of spaces, especially offices. The upper and lower ends of this solution have flared shape, to increase the contact surface, which prevents the coating from coating said upper and lower ends. This antecedent does not propose that the prop is divisible, with which its handling and transport will be complicated and expensive.

GB695937 also describes an element with similar characteristics, and in this case the strut is divided into two segments, which are of different diameter and telescopically joined, and which includes an elastic element and a threaded element to regulate the total length of the strut, and to include an elastic tension to dock the strut, but, apart from being two segments of different diameter, requires the introduction of a pin to make the functions of stop, on which the threaded element acts to separate the two segments. Document US4449876 discloses a threaded element integrated with an element elastically displaceable with a spring, and both integrated with a connector element that allows coupling this device to the end of a wooden prop, provided that it can be docked inside a vehicle for secure a load. This embodiment does not include any tubular element in which to insert said threaded or displaceable elements. In addition, the connecting thread that joins the threaded element to the rest is part of the displaceable element, and therefore can move when free. To avoid that, when turning the threaded element, the union thread also rotates, this has a rectangular shape and is inserted in a rectangular compartment.

On the extensible strut, a cladding can be fixed, by means of fixation devices, of the type having two elastically deformed facing arms, which can be anchored and un-anchored from the strut, and which are attached to a coupling configuration complementary to the cladding panels. .

Document DE202006005611 describes an embodiment of said fixing device, but which is not intended to cover two opposite faces of the same group of struts, nor to allow the facing panels of both faces to face each other.

Also the document FR2936827 describes a similar product, with the same deficiencies.

The fastening of cladding panels on tubular elements is known, for example, from the patent DE202004016792U, in which a system of extensible struts on which spacer panels are fixed is described.

Another document describing an extensible strut on which separator panels can be fixed by means of fixing devices is document ES1117832U, presented by the same applicant of the present invention.

Documents describing fastening devices that can be coupled to a tubular element and are provided with a coupling configuration that allows the fixing of panels are also known. An example is document EP1850045A1, which describes clamps of opposing elastically deformable arms attached to a support which integrates a coupling configuration.

BRIEF DESCRIPTION OF THE INVENTION

The present invention concerns an extendable strut, which has:

• a tubular strut element defining a longitudinal direction; • at least one threaded element, which is partially housed inside said tubular strut element, and joined thereto by means of a connecting thread that provides an adjustable insertion and / or removal of said threaded element with respect to said tubular strut element , thereby increasing or reducing the total length of the extensible strut in the longitudinal direction; Y

• at least one compressible elastic element capable of reducing the total length of the extensible strut, when said extensible strut is subjected to axial compression in the longitudinal direction.

In this way, the threaded element makes it possible to increase or decrease the total length of the extendable strut when rotating with respect to the connecting thread, adapting the total length of the extendable strut to the existing separation between two parallel planes between which it is desired to anchor said extensible strut.

The threaded element can be a cylindrical body with one or more threads on its outer face, and inserted inside the tubular element, where the connection thread is, which can consist of one or more female threads practiced directly on the inner face of said tubular element, or consist of a threaded bushing with a hollow cylindrical interior in which one or more threads have been made, said bushing being fixed to the tubular element.

The thread can be one, or it can be several threads providing several entries to the thread. The thread pitch can also be of different width to achieve a faster or slower adjustment of the threaded element. The fact of having several threads allows to have a greater or equal thread pitch, having an equal or lesser tooth height, than if a single thread were available.

Said elastic element is joined to a displaceable element which in turn is movably connected, in the longitudinal axial direction, to the tubular strut element, so that by exerting compression on the extensible strut in said direction, a relative displacement occurs between the displaceable element and the tubular strut element, offering an elastic resistance provided by the elastic element.

Said elastic element can be, preferably not limiting, a spring with one of its ends fixed with respect to the tubular strut element, by means of a projection, a stop or a pin for example. Other solutions of equivalent elastic elements are also accepted, such as the use of a pneumatic piston or an elastomer. Said movable element may be an element with an outer section of a smaller size to the inner section of the hollow profile in which it is inserted, being loose and allowing a relative longitudinal displacement.

The tubular strut element is composed of a plurality of tubular segments of equal size of outer section, arranged coaxially and co-aligned, all the tubular segments forming the tubular strut being capable of being joined to each other by at least one element connector

Said plurality of tubular segments may be, in a non-limiting manner, a first tubular element and a second tubular element. Optionally, the plurality of tubular segments can include additional tubular elements, which can be joined to the first and second tubular elements to obtain a longer strut, or segments of tubular element of shorter length and therefore more manageable. Said additional tubular elements will have the same outer section as the first and second tubular elements, and will connect to each other or to said first and second tubular elements by means of the threaded element, the displaceable element, the connecting element, or by additional connecting elements.

The individual length of each individual tubular segment is less than three quarters of the total length of the extensible strut at its maximum extension, and is preferably half the tubular strut element in the absence of additional tubular elements, and of a a third or a quarter of the length of the strut tubular element in case of having respectively one or two additional tubular elements, in this way they can be transported more easily and economically in a package of shorter length, or even be sent by a courier service, reducing logistics costs, and facilitating the purchase-sale at a distance.

Preferably, each of the tubular segments of the plurality of tubular segments will have a length of less than 110 cm.

One or all of the tubular segments may be of a metallic material, preferably aluminum, and have a protective surface finish such as anodizing, lacquering, varnishing, galvanizing, painting, or any other, and may have a smooth, fluted, toothed exterior finish , with notches or perforations.

The connecting element that allows to join two tubular segments together can be, by way of example, an element with an outer section of a size equal to or scarcely inferior to the inner section of one of said tubular segments, thus allowing the manual insertion adjusted to a portion of said connector element within each of the Tubular segments, by a non-specialized user and without the use of tools, thus achieving a rigid connection. Optionally, the relative rotation between said connector element and the tubular segment can be allowed, and said rotation can be facilitated by, for example, the use of materials with a low coefficient of friction, such as Teflon, or lubricants.

Other configurations of the connecting elements are admitted, such as threaded joints, conical connections, or by screws or pins that will be complementary with coupling configurations provided at the end of the tubular segments. In the case of the threaded connection, the coupling is carried out by means of a machined connection thread on the inner face of the tubular segment, or by means of a threaded connection sleeve fixed on said tubular segment.

Said connector element can have a maximum insertion limiter, which regulates the depth of insertion of the connector element within the tubular segments it connects. Said maximum insertion limiter may be, by way of example, a central portion of the connector element with an outer section of a size greater than the size of the inner section of said tubular segments, thereby making the stop functions. Preferably, this maximum insertion limiter will have an outer section of the same size as the outer section of the tubular segments.

The threaded element will be connected, by means of said connecting thread, to one end of a tubular segment.

The displaceable element will be attached to one end of a tubular segment.

Optionally, the connector element will also be attached to one end of a tubular segment.

It also contemplates the optional non-limiting possibility that the displaceable element is integrated with the threaded element, or that the displaceable element is integrated with the connecting element, or that the connecting element is integrated with the threaded element, or that the displaceable element and the Connector element are integrated with the threaded element.

Thus, by way of non-limiting example, the threaded element can perform the functions of connecting element, and be located between two consecutive tubular segments, as for example between the first and the second tubular elements, just as the displaceable element can occupy this position and also perform the function of the connector element. The upper and lower end of the extendable strut can have a high coefficient of friction element, disposed on each of the contact surfaces of the extendable strut with said two parallel planes. These elements, together with the compressive force of the elastic element introduced by extending the extensible strut through the threaded element, produce a secure berthing of the extendable strut, it being very difficult for an external force exerted in a direction perpendicular to the longitudinal direction, can move one of the two ends of the extendable strut laterally.

In addition, a stop piece can be added, for example in the form of a ring with an internal recess where the end of the strut would fit snugly, and externally of rectangular, square, circular, etc. geometry, fixed on one or both planes. parallel, by means of adhesives or mechanical fixation, thus making lateral displacement even more difficult. It can also serve as a guide for an initial positioning of the extendable strut during its installation.

Said high coefficient of friction elements, for example rubber, rubber or neoprene parts, can be fixed directly to the ends furthest from the two most distant tubular segments, for example at the free ends of the first and second tubular element. It is also contemplated that said high coefficient of friction elements may be fixed to the end of the displaceable element or of the threaded element.

Additionally, said element of high coefficient of friction can be linked to the end of a tubular segment by means of a rotary union that allows its relative rotation around an axis parallel to the longitudinal direction, offering little friction, for example by means of a disc of a material of low coefficient of friction, for example Teflon, or by a disc attached to an axle and equipped with a bearing.

Said rotary union can allow a tubular segment to rotate with respect to the other tubular segment, for example during the adjustment of the threaded element, without causing the rotation or movement of the high coefficient of friction element with respect to the plane on which it rests.

According to an alternative embodiment, said rotary union includes a threaded regulator that allows, by its rotation, the distance or approach of said element with high coefficient of friction of the respective tubular segment. This threaded regulator can allow to increase or decrease in a precise way the tension that the extendable prop exerts on the parallel planes to which it is anchored, regulated by the elastic element connected to the displaceable element.

Optionally, the displaceable element can also be provided with an indicating device which indicates, visually, the amount of elastic force exerted by said elastic element when subjected to compression. An example of embodiment of said indicator device can be, by way of example, a rule that allows to measure the relative displacement between the displaceable element and the tubular segment that houses it, which by means of the Hook's law, allows us to know the elastic force exercised.

These characteristics allow the aforementioned extendable strut to be used as an active propping that exerts an axial force on the parallel planes against which the strut is moored, being able also to regulate the intensity of said axial force thanks to the indicating device. It also allows the strut to admit and absorb relative movements between the two parallel planes by loading and unloading the elastic element, without its position and function being compromised.

Thus, berthing of the strut requires first joining the plurality of tubular segments, for example the first and the second tubular element, by means of at least one connecting element. Then present the strut in the desired position, and proceed to increase the length of the strut, by adjusting the threaded element, until the ends of the strut come in contact with the two parallel planes, then you have to increase the active tension exerted by the elastic element, by additional adjustment of the threaded element, or optionally by the relative rotation of the threaded regulators with respect to the extendable strut, until the voltage indicated by the indicating device is the desired one.

In an alternative application, this extendable strut can be used to fix equipment in interiors in a provisional and removable way, such as for holding spotlights, or speakers for events.

In another alternative application, a plurality of vertical struts can be fixed by being optionally aligned and equidistant, in an easy and tool-less way by an inexperienced user. Said plurality of struts can serve as a support structure to support a covering, an enclosure or a space-dividing element, such as rigid panels of wood, plastic, resins, glass, plaster, ceramics, stone, agglomerated materials, furniture, etc. , or flexible elements such as curtains or blinds. These elements could be fixed on the extensible strut by means of removable and reusable fastening devices, such as elastic deformation joining systems.

In some of these applications, the feature that all the segments of the plurality of tubular segments have the same outer section is advantageous, because this allows a standardized fixing device to be fixed on said strut at any point of its length.

The inner section of the tubular segments can be different, varying the thickness of their outer walls, adapting better to the loads supported by each of the tubular elements, or to the required coupling configurations.

It is also advantageous in some cases that all the tubular segments have a circular section, since it allows said fixing elements to be indistinctly located in any angular position.

In case it is desired to fix a fastening device on the exposed section of the threaded element, which by definition will have a section different from that of the tubular segments, a third tubular element, provided with a connecting thread, can be provided, positioned on said exposed fraction of the threaded element, which can be placed in any longitudinal position of said exposed threaded element, serving as a support for the fixing device. Said third tubular element can also be used to block the position of the threaded element with respect to the connecting thread with a tubular segment, acting as a locking screw.

The possibility has been foreseen that the tubular segments have perforations in their outer walls, to allow the passage of conduits through their interior, for the fixation of elements in their surface, or for the insertion of tools to facilitate their regulation, as well as The wall finish of the tubular segments can be smooth, but also grooved, notched, multi-perforated or serrated, to favor connectivity with external joining elements.

Finally, it is also considered optimal that no element of the extensible strut protrudes from the plane defined by the outer face of the tubular segments, as this prevents any element of the strut from interfering with a fixing device or with an element fixed in any position of the strut extendable, in addition to reporting aesthetic and security benefits, by not having outstanding elements with which a user could be harmed. The strut described can also include a plurality of removable fixing devices for covering plates on said tubular elements, which allows the erection of enclosures, partitions or walls on a support structure formed by a plurality of tubular elements, in a fast way , safe and simple, without the use of tools.

Said tubular elements can be of different nature, being able to be joined upright on a support, or struts moored between a floor and a roof.

The proposed plate fixing device comprises:

A clamp having a first arm and a second arm facing each other, elastically deformable, both arms being provided with a proximal end and a distal end, the proximal ends of the first and second arms being joined to a support, and the distal ends being of the first and second arms facing and distanced from each other, said distance being less than a measure of width of a tubular element, and the clamp being engageable and uncoupling from said tubular element by elastic deformation under pressure of said first and second arms;

• at least one coupling configuration, arranged on said support, to which at least one panel of the covering is removably fixable;

the tubular element being a linear element elongated in the direction of a longitudinal axis. Thus, said clamp can be coupled on said tubular element by elastic deformation of the first and second facing arms of the clamp. Said coupling will be achieved by pressing the clamp against the tubular element, exerting a force transverse to the longitudinal axis of said tubular element.

After the coupling, the first and second arms will remain surrounding the tubular element, retained, and for their decoupling, a force transverse to the longitudinal axis equivalent to that used for the coupling will be required, but in the opposite direction.

Both arms of the clamp share a common support disposed at its base, and on which at least one coupling configuration is provided that allows a removable attachment of at least one cladding panel.

Said fixing device has at least one crimping configuration disposed in at least one of the first or second arms, said crimping configuration being engageable with another complementary crimping configuration of another fixing device provided with at least one support and crimping configurations, forming the assembly of both coupled fastening devices, a fence fitted around the tubular element.

Optionally, it is contemplated that the other fixation device is identical to the fixation device initially described.

Thus two complementary and optionally identical fixing devices can be mutually coupled by coupling the respective crimping configurations. The result of said mutual coupling will be a frame surrounding the tubular element, reinforcing and fixing the relative position of both fixing devices, which will be arranged with the corresponding supports on opposite sides of the tubular element, and preferably both supports being at the same height with respect to the longitudinal axis that determines the tubular element.

According to another embodiment, said other fixing device also includes a first and a second arms, and the initially described fastening device being coupled to said other fixing device which is optionally identical to the first, the proximal part of the first and second arms of the The fixation device is juxtaposed to the distal part of the first and second arms of the other fixation device. According to this embodiment, the coupling is obtained by the juxtaposition of both clamps arranged around a tubular element, placing them laterally adjacent and adjacent, leaving their respective arms also juxtaposed.

Preferably the direction of coupling and decoupling of the clamping configuration of the clamp, with respect to the crimping configuration of the other clamp, is approximately parallel to the longitudinal axis of the tubular element, the clamps being coupled to said tubular element. This means that the direction of mutual coupling of the crimping configurations is approximately perpendicular to the direction of coupling and decoupling of the clamps with respect to the tubular element, requiring a first decoupling of the crimping configurations in order to be able to proceed with the release of the clamps to the tubular element. This makes it possible to obtain a much firmer connection of the clamps to the tubular element, and consequently of the cladding panels to the support.

Said support has coupling configurations, provided for the simultaneous removable fixation of at least two laterally adjacent, adjacent and coplanar panels on one side of the support, said panels being parallel to the longitudinal axis of the tubular element.

According to one embodiment, said anchoring occurs in a joining configuration close to an upper corner of each of the two panels. This means that in order to support said panels it will be necessary that another joining configuration next to the other upper corner of each of the panels is coupled to a different additional fixing device, anchored on a different and parallel tubular element, thus providing at least two binding configurations to each panel, making it stable.

Optionally a coupling configuration of a fixing device can anchor, in addition to two laterally adjacent panels by one of its upper corners, one or two additional panels, located in an overlapping position and coplanar with the two panels described, by a joining configuration of each additional panel located next to one of its lower corners. In this way it is achieved that four panels are coupled to a single fixing device. Obviously the additional panels overlapped require additional binding configurations to be stable, anchored to different fastening devices, each panel being supported by its four corners by four different fastening devices.

It is also contemplated that the laterally adjacent and / or superimposed panels are mutually coupled by a tongue-and-groove configuration provided on their mutually facing side faces.

According to a preferred embodiment, said coupling configuration has at least one rectangular main projection protruding perpendicularly from the support, having two main faces perpendicular to the longitudinal axis of the tubular element, the fixing device being anchored to said tubular element. Said two main faces will be those of greater length of the main projection, and are intended to interact with parallel complementary faces provided inside a main groove made in each panel that forms the connection configuration of said panel to the fixing device.

Said main projection provides the vertical positioning of the panel when it is coupled inside said main slot, providing the coupling of the coupling configuration with the panel joining configuration. The main faces of the main projection can be pressed against the inner walls of the main groove or can optionally remain with some clearance. Preferably, each panel rests on the immediately lower panel, transmitting the vertical forces from one panel to the other, until reaching the lower panel that can transmit the loads to the floor, or to a lower profile of the base on which said panels are supported. inferiors The contact between the overlapping panels can be done by means of a tongue and groove configuration provided with projections and grooves, or complementary steps, which prevent a relative horizontal movement between the overlapping panels.

It is also proposed the inclusion of actionable retainers fixed on the rear face of the panels, and intended to press and retain the coupling configurations within the joint configurations of the panels.

Said projection will have, preferably, a thickness of 3 millimeters, and about 4 millimeters will protrude from the support. Its length will be at least 40 millimeters, and ideally 58 millimeters. So these main faces will have a length of 58 millimeters and a width of 4 millimeters.

The main groove will consequently have a minimum width of 3mm and a depth of 4mm, being able to have an optional clearance of one or two millimeters. Said main groove will ideally be connected to a side face of the panel, so that by placing two laterally adjacent panels, coplanar and aligned, their respective main grooves will also be aligned. The combined length of said two aligned main slots will be equal to or greater than that of the complementary main projection.

It is also contemplated that said main faces have embossments, fins or harpoon-type retainers, which retain said main projections within the main grooves by means of an elastic expansion force.

Additionally, the coupling configuration can include other secondary projections that fix the horizontal position of the panels with respect to the fixing device, allowing it to be anchored in a single position.

By way of example, two rectangular secondary projections are provided which each have two faces parallel to the longitudinal axis of the tubular element, and are therefore perpendicular to the main projection. Said two secondary projections will each be placed adjacent one of the two ends of the main projection, preferably symmetrically with respect to a vertical plane, each of said two secondary projections being coupled to a secondary vertical slot provided in a position adjacent to the Top corners of each panel. By way of non-limiting example, said secondary projections may each have a thickness of 3mm and protrude perpendicularly from the support about 4mm, its length being, for example, 18mm. The separation between both secondary projections can be 82mm.

According to another embodiment, each coupling configuration includes, in addition to the horizontal main projection and the two symmetrical vertical secondary projections, another additional projection that will ideally be symmetrical to the main projection with respect to a horizontal plane, provided to be coupled to additional slots provided in a position adjacent to the lower corners of two other overlapping panels.

The separation between the main projection and the additional projection can be, by way of example, 64mm.

It will be apparent that different geometries and distances of the coupling configurations are applicable without altering the essence of the invention, and that other types of coupling configurations will be equally acceptable, such as for example hook configurations, lugs, or even magnets or screws .

According to a specific embodiment in which the two fixing devices mutually crimped through the crimping configurations around the tubular element are identical, said horizontal symmetry plane of the coupling configurations of the support of one of the fixing devices is coplanar with another plane of symmetry of the coupling configurations of the support of the other fixing device. This allows the coupling configurations of the clamp, and of the other clamp to face each other on opposite sides of the tubular element, and therefore the panels attached to them, located on opposite faces of the tubular element, would also be aligned and facing each other.

According to this or another similar embodiment, with the clamp coupled to the other clamp, the first arm of the clamp is juxtaposed and laterally adjacent to the first arm of the other clamp, and the second arm of the clamp is juxtaposed and laterally adjacent to the clamp. second arm of the other clamp. This arrangement implies that the support of the two juxtaposed clamps are on opposite sides of the tubular element, and that the corresponding arms are laterally adjacent and in contact, the other clamp being arranged in an inverted position with respect to the initial clamp.

Preferably the arms are joined to the support, the crimping configurations being placed in a plane of symmetry of the support, said plane being perpendicular to the longitudinal axis of the structural element, thus when coupling two clamps by means of said crimping configurations, the supports of both clamps will be located on opposite sides of the tubular element and at the same height with respect to the longitudinal axis that determines the tubular element.

Concerning the crimping configurations that allow the mutual coupling of the clamp with another clamp, each first and second arm consists of two crimping configurations.

If the clamp is joined to another fixing device lacking arms, said crimping configurations should be located at the distal ends of said arms of the clamp, in order to reach the other crimping device and allow its coupling to other crimping configurations of the other fixing device, allowing an anchorage fitted around the tubular element.

On the contrary, in case said clamp is linked to another identical clamp, on each arm of both clamps a first crimping configuration disposed in a more proximal position of the support and a second crimping configuration disposed in a more distal position will be arranged. that the first crimping configuration, arranging the first and second crimping configurations of complementary coupling geometries, which allows them to be coupled together.

Said crimping configurations may also be of a different nature, such as, for example, plug-in lugs, toothed profiles, hooks, clips, etc.

Additionally, the cladding panels include operable retainers that have a retention position, in which they prevent the release of the coupling configurations with respect to the panels, and a release position, in which they do not interfere with said coupling means. .

Said retainers may be, by way of non-limiting illustrative example, a bolt or a bollard coupled to the rear face of the panel, which in a retaining position is partially superimposed on the support and preventing, either alone or in combination with the configuration of coupling, the separation of the panel with respect to said support.

The described fastening device is intended to be fixed around the above-described tubular element, which preferably will be a cylindrical tubular extensible element. To said fixing device panels can be coupled, by means of the coupling configurations described above, obtaining the tubular element assembly, fixing device and panels to create an enclosure, partition or removable wall, said elements being constituent parts of a kit for the erection of partitions. So said kit for the erection of walls includes:

• a plurality of extendable struts movables between two parallel planes;

• a plurality of fastening devices engageable with said extendable struts; Y

• a plurality of panels coupled to said fixing devices.

Each of the extensible struts comprises, preferably:

• at least one hollow tubular element, endowed with an upper end and a lower end, defining a longitudinal direction;

• at least one threaded element partially housed inside said tubular element, joined to the tubular element by means of a connecting thread that provides an adjustable insertion and / or removal of said threaded element with respect to said tubular element, thereby increasing or reducing the total length of the extensible strut;

• at least one compressible elastic element capable of reducing the total length of the extendable post when said extensible post is subjected to axial compression in the longitudinal direction, said elastic element being connected with a displaceable element, which moves in the longitudinal axial direction of the tubular element, offering an elastic resistance to said movement;

• the hollow tubular element is composed of a plurality of tubular segments, with equal size of outer section, arranged coaxially and co-aligned, said tubular segments being capable of being joined by at least one connector element;

• the length of each of said tubular segments is less than three quarters of the total length of the extendable strut in its extended position; Y

• said connecting thread establishes a connection of the threaded element with one end of one of said tubular segments.

Each of said fixing devices includes the coupling configurations described, and preferably also the rest of the characteristics described so far.

Each of said panels is rectangular and rigid and preferably includes:

a rectangular front face, delimited by an upper edge face, a lower edge face and two side edge faces, which in turn delimit a rectangular rear face parallel to said front face; including each panel, on its rear face, complementary connection configurations with, and intended to be coupled to, the coupling configurations of the fastening devices.

Said connecting configurations allow the panels to be coupled to the extensible struts by means of the fixing devices.

Optionally actionable retainers are provided, which are designed to retain the coupling configurations within the joining configurations of the panels, being in the retention position.

Preferably said joining configurations consist of grooves complementary to the coupling configurations of the fixing devices, which consist of projections, the projections and grooves being dimensioned to achieve a tight insertion, or with certain determined clearance. Said grooves will preferably be perpendicular to the rear face and parallel to the upper and lower edge face, and will be located at positions adjacent said edge faces.

According to an embodiment, each panel has union configurations in its four corners, allowing said panel to be supported by means of its coupling with four fastening devices arranged in said corners, and which are also shared with adjacent, adjacent and coplanar panels, of so that each clamping device supports a corner of two laterally adjacent panels, or of four laterally adjacent panels.

In an exemplary embodiment, said groove forming the joining configuration of the panel is horizontal and extends from the edge side face to a certain distance away from said edge side face, repeating the same at all four corners. By placing two laterally adjacent panels, said slots are aligned so that a coupling configuration provided in a fixing device can be formed by a main projection which is coupled simultaneously in both slots of two adjacent panels.

Additionally, the coupling configuration of the fixing device can also have secondary projections, perpendicular to the main projections, which are coupled to secondary grooves also provided in the vicinity of the corners of the panel, integrating the joining configuration. This also allows the panel to be fixed horizontally.

It is also contemplated that the upper edge and lower edge faces have a tongue-and-groove or step-shaped profile, allowing a coupling between two vertically overlapping panels and ensuring a correct positioning of the panels, a correct transmission of vertical loads from one panel to another, and preventing an individual panel from being extracted horizontally. Said tongue and groove profile, in combination with a drivable retainer that prevents the extraction of the coupling configurations from the panel joining configurations, in a horizontal direction, will allow vertically transmitting the loads, and will prevent a horizontal uncoupling of the panels from the devices Fixing.

Other elements can also be included in the kit in an optional way, such as for example a base element, an upper top element, a side end element, a door element, etc.

The base element will be laid on a floor, and to support the panels of the partition or wall superimposed on said base, which in turn will support the weight of the other panels superposed thereto.

On the contrary, the upper and lateral top elements will serve to fix the wall or partition assembly to pre-existing side walls and roof, and / or to adapt the partition or removable wall to possible projections or existing reliefs in the pre-existing walls and ceiling.

The said proposed kit can include all the features claimed in the present invention.

The constituent elements of said kit form a system for the erection of walls. Thus, the constituent elements of said kit can be assembled following the following steps. First place the tubular elements docked between a floor and a roof, in vertical position, and separated from each other by a distance equal to the length of the panels. Some skirting elements can be placed on the floor following the base of the enclosure to be erected after the placement of the struts or, preferably, prior to said positioning of the struts, which can be positioned by means of openings made in said base elements, in the that insert the lower end of the tubular elements. Next, the fixation devices, linked to other fixing devices, are placed on all the tubular elements on which it is desired to fix panels. Finally, the panels are placed, beginning with the lower row, whose lower end is coupled to the base elements by means of a tongue-and-groove or step configuration, and whose upper end is anchored to fixing devices of each tubular element located at the correct height to allow said coupling being the lower row of panels coupled to the element of plinth. Said anchoring with the fixing devices is produced by inserting the coupling configurations within the panel connection configurations, and by actuating the operable retainer, which prevents its disengagement. The rows of successive panels are placed by coupling their lower end with the upper edge of the preceding panel row by means of a tongue-and-groove or step configuration, and coupling its upper end to other fastening devices attached to the tubular elements in a position that allows it in a way equal to that described for the lower row. The operation is repeated until the erection of the wall is completed.

Detailed description of an embodiment

According to an example of non-limiting embodiment shown in Fig. 1, the extendable strut 1 can be docked between a parallel floor and a roof, and comprises a plurality of tubular segments formed by a first tubular element 11 and a second tubular element 12, both hollow, cylindrical and of equal internal and external diameter made of aluminum. Its outer diameter is less than 6 cm, the thickness of its wall is a few millimeters, and both first and second tubular elements 11 and 12 have a length of approximately 110 cm, so that its overall sum does not exceed 220 cm. The length of the first and second tubular elements may be different from each other.

Both first and second tubular elements 11 and 12 can be coupled and decoupled from each other in the longitudinal direction, in the manner shown in Fig. 3, by a connector element 22, the joint resulting from its joining forming a tubular element of strut 2. In this embodiment, the first tubular element 11 has, at one of its ends, a complementary connection thread 21 with a threaded element 20. Said threaded element 20 is a hollow tube with one or more threaded threads made in a portion of its face outer, which can be screwed and unscrewed from the female thread 21 inserted and fixed inside the end of the first tubular element 11. In this way, the threaded element 20 is fixed to the first tubular element 11 and can regulate its insertion and relative extraction with respect to it by means of its threaded turn. By way of example, the threaded element 20 can have a threaded length of 60 cm, which would make it possible to vary the total length of the extendable strut 1 by about 45 cm by means of said regulation, and may have perforations in its perimeter that allow the insertion of a removable key that allows the threaded element 20 to rotate, exerting angular force.

The end of the threaded element 20 that is not inserted in the first tubular element 11 has integrated, in this non-limiting embodiment, a connector element 22 that allows its connection with one end of the second tubular element 12, thus achieving the union of the first and the second tubular elements 11 and 12. In this first embodiment, shown in Fig. 3a and 4a, the connector element 22 consists of a cylinder with an outer diameter equal to or smaller than the inner diameter of the second tubular element 12, so that it can be inserted in its interior manually, in the longitudinal direction of the second tubular element 12. In a second alternative embodiment shown in Fig. 3b and 4b, the connector element consists of a thread of connection with the second tubular element 12, which would be provided with the corresponding connecting thread, for example a bushing of connecting thread 16, or a thread machined directly on the inner face of the second tubular element 12.

This first and second embodiment allows the threaded element 20 to be in an intermediate position of the extendable strut 1, being much more accessible to an operator, and being more comfortable to handle, but as it is obvious, this element could be found in one of the ends of the extendable strut 1.

A maximum insertion limiter 23 borders the threaded element 20 and the connector element 22, preventing a part of the threaded element 20 from being inserted into the interior of the second tubular element 12. This maximum insertion limiter 23 is an intermediate portion of the element with an outer diameter equal to the outer diameter of the second tubular element 12 thus preventing its insertion. The aforementioned maximum insertion limiter 23 can have, in turn, perforations in which to insert a lever that helps rotate the threaded element 20 with respect to the first tubular element 11, thus regulating its insertion or removal thereof, and consequently, regulating the height total of the tubular element of strut 2 resulting from the union of the first and second tubular elements 11 and 12. The second tubular element 12 has a displaceable element 24 partially inserted at one of its ends and joined to it without impeding its displacement, in the longitudinal direction of the second tubular element 12. This displaceable element 24 contains inside it an elastic element 25 which it has an end fixed to the second tubular element 12. This construction allows the displaceable element 24 to move in the longitudinal direction of the tubular element when subjected to a force, opposing an elastic resistance to said movement provided by the elastic element 25.

According to an exemplary embodiment, the displaceable element 24 is a tubular element with an outer diameter of less than the inner diameter of the second tubular element 12, with a closed end. In its interior a spring acts as an elastic element 25, which has an end joined to the second tubular element 12 by means of for example a pin 26.

Additionally, an indicator device 27 allows to know the tension exerted by the spring, for example by a rule that measures the relative displacement between the displaceable element 24 and the second tubular element 12, which makes it possible to know the tension of the elastic element 25 by means of the law of Hooke

According to a preferred embodiment, the indicator device 27 is a screw 28 inserted perpendicularly into the tubular wall of the movable element 24, in the fraction of said movable element 24 inserted inside the second tubular element 12, the head of said torillo 28 being left protruding from the element. displaceable 24, and preferably flush with the outer face of the second tubular element 12. Said head is fitted inside a slot elongated in the longitudinal direction, made in the cylindrical wall of the end of the second tubular element 12. Thus, said head of the screw 28 acts as a retainer of the displaceable element 24, preventing its exit from the interior of the second tubular element 12, while allowing its movement along the elongated slot, and at the same time allowing an operator to see the position of the displaceable element 24 through the position of the screw head 28, thus acting as indicator device 27.

The end of the displaceable element 24 is provided with a high coefficient of friction element 29, like the free end of the first tubular element 11, which makes it difficult for a force perpendicular to the extendable strut 1 to move it from its position, since said strut is extendable 1 snapped against the roof and the ground. Said high coefficient of friction element 29 can be mounted on a plate joined by an axis with bearings to the end of a tubular element 11 or 12, or to the end of a displaceable element 24 or to the end of a threaded element 20, or to use a joint of a material with low coefficient of friction as teflon to facilitate its rotation.

Optionally one or more third tubular elements 13 of short length, provided with a connecting thread, can be arranged in the threaded segment of the threaded element 20 that is not housed inside the first tubular element 11. Thanks to the connecting thread, said third tubular element 13 can regulate its longitudinal position on said segment. This allows it to be used to block the position of the threaded element, by pressing said third tubular element against the first tubular element 11, through the threaded socket 16, thus blocking the connecting thread, or allowing it to be placed in a position longitudinal any of said threaded element to serve as support for a possible fixing device.

The extendable strut 1 of this embodiment has no element projecting from the plane formed by the outer cylindrical wall of the tubular element.

A plurality of these extensible struts 1 can optionally be located in parallel and equidistant, to later support a coating composed of panels fixed removably on said extensible struts 1, on one or both sides, by means of fixing devices.

The combination of the extendable strut 1, the fixing device and the cladding panels provides an enclosure system, which allows the erection of enclosures in a simple, clean and removable way, allowing their reuse in a different location, and the packaging of the entire system in a package of small size and easy transport.

An alternative embodiment (not shown) is also contemplated in which the plurality of tubular segments includes, in addition to the first and second tubular elements 11 and 12, additional tubular elements of the same characteristics, which can be connected to said first and second tubular elements. 11 and 12 through additional connector elements 22, thus increasing the maximum total length of the extendable strut.

According to an example of non-limiting embodiment shown in FIG. 6, the strut includes a fixing device 30 consisting of a clamp 31 formed by a first arm 32 and a second arm 33 facing each other, which are joined at their proximal end to a support 34 from which they project approximately perpendicularly. The extreme distal of both arms 32 and 33 are facing and distanced, the distance of separation being less than a width distance of a tubular element 2, the tubular element being an elongate element of constant section along a longitudinal axis E, and being , in this example of embodiment, an extendable strut of circular section movable between a floor and a roof.

Said separation distance, together with the capacity of the arms to be elastically deformable, allows said clamp 31 to be coupled and uncoupled from the tubular element 2 exerting a force perpendicular to the longitudinal axis E, which causes said elastic deformation of the arms remaining behind. its coupling attached to the tubular element 2 in the manner shown in Fig. 7.

Said support 34 has, on a face opposite the face in which said arms are joined, coupling configurations 35, which include a main projection 36 provided with two main faces perpendicular to the longitudinal axis of the tubular element, an additional projection 38 symmetrical to the main projection 36 with respect to a plane of symmetry perpendicular to the longitudinal axis and two secondary projections 37 each with two faces parallel to the longitudinal axis, said two secondary projections 37 being symmetrical with respect to a plane parallel to the longitudinal axis. Said coupling configurations 35 allow the fixing of coating panels 40 on said tubular element, by means of said fixing device, the panels 40 being parallel to said longitudinal axis E.

In the present embodiment each main projection 36, additional 38 and secondary 37 has a rectangular section, which is complementary to a corresponding major, additional and secondary groove 46 on the back of the covering panels 40, as seen in FIG. Fig. 6

The projections measure 3 mm wide and 4 mm high with respect to the support 34, and are arranged symmetrically with respect to a plane of symmetry perpendicular to the longitudinal axis E with the fixing device 30 being coupled to the tubular element 2.

With the slots 46, 47 and 48 practiced in areas close to the corners of the panels 40, four corners of four different panels 40 can be anchored on the same fixing device 30 by inserting said projections 36, 37 and 38 in said slots 46, 47 and 48, allowing the fixing of said four panels 40 in a laterally adjacent position and coplanar. By placing a fixing device 30 in each of the corners of each panel 40, the covering can be extended in all directions, while obtaining a fixation of each of the panels 40. To ensure that said panels 40 are not uncoupled from the coupling configurations, actuable retainers 50 pivotally attached on the rear face of the panels are provided, so that after the panel is coupled to the fixing device, the actuation of said actionable retainers 50 press and retain the coupling configurations 35 within the slots provided in the rear face of the panel 40, in the manner shown in Fig. 7. For the same purpose it is also contemplated that the adjacent panels are laterally coupled by a tongue and groove or a stepped configuration, as shown in Fig. 10.

The proposed fastening device 30 also includes crimp configurations 39, which in the embodiment shown in Fig. 6 and 7 consist of two crimp configurations arranged in each of the first and second arms 32 and 33, four being in total.

In each arm there is provided a configuration of crimp 39 in the form of a projection and a configuration of crimp 39 complementary to said protruding form, in the example shown the protruding form is a cylindrical or frustoconical lug, and the complementary form is a cylindrical or frustoconical hollow. .

Said crimping configurations 39 allow that, having another fixing device 30 'identical to the fixing device 30 described, both can be mutually coupled by the mutual coupling of their corresponding crimping configurations 39 and 39'.

To obtain the mutual connection of the two fixing devices 30 and 30 ', it is necessary to overlap or juxtapose respective clamps 31 and 31', arranging the distal end of the first and second arms 32 'and 33' of the other fixing device 30 '. laterally adjacent to the proximal end of the first and second arms 32 and 33 of the initial fixation device 30, and also arranging the proximal end of said arms of the other laterally adjacent fixation device 30 'on the distal end of the arms of the device initial 30 fixation.

By means of said juxtaposition, it is possible to align the arms and the crimping configurations 39 and 39 'of the two fixing devices 30 and 30', while at the same time achieving that both supports 34 are on opposite sides and the coupling configurations 35 oriented towards opposite sides, allowing the fastening of panels 40 parallel to each other on opposite sides of the tubular element 2 on which said fixing devices 30 and 30 'are fixed. The alignment of the crimping configurations 39 and 39 'of the two fixing devices 30 and 30' allows their mutual coupling, in the example illustrated here by inserting the cylindrical lugs into the cylindrical recesses.

In the illustrated example, the crimping configurations 39 of the first arm 32 of the fixing device 30 are coupled to the engagement configurations 39 'of the first arm 32' of the other fixing device 30 ', and those of the second arm 33 with the of the other second arm 33 '. This is possible only if the position of the other fixing device 30 'is inverted with respect to the position of the initial fixing device 30.

The direction of insertion of the cylindrical lugs inside the cylindrical hollows is parallel to the longitudinal axis E of the tubular element 2, the fixing devices 30 and 30 'being coupled to said tubular element 2, said coupling direction being perpendicular to the direction of coupling of the fixing devices 30 and 30 'to the tubular element 2. This means that when the crimping configurations 39 and 39' are mutually coupled, the fixing devices 30 and 30 'can not be decoupled from the tubular element 2, since they form a fence around it and the crimping configurations 39 and 39 'prevent a relative displacement between both fixing devices in that direction.
