Description

The invention relates to a device for assembling elements

  particularly long-limbed structural

  demountable construction of assemblies such as shelves.

  It also relates to the assemblies thus obtained.

  Such assemblies generally comprise - on the one hand, uprights, each consisting of two posts held substantially parallel to each other by spacer elements and - on the other hand, interconnecting elements intended to be arranged approximately horizontally between two lontants so as to maintain rigidly these in generally parallel and vertical planes and if necessary to serve as a support for trays thus constituting stables. In general, the aforementioned structural elements, ie the posts, the spacer elements of these posts and the interconnection elements of the uprights constituted by struts are each generally tubular and

  polygonal quadrangular section.

  Conventionally, to give a certain rigidity to the assembly, despite its removable nature, the columns of the uprights are joined rigidly by elements of bracing welded or bolted and only the elements

  interconnect amounts are easily removable.

  For this purpose, each end of an interconnection element cooperates with a pole by a hook-type assembly means which is interposed between two

  surfaces of the elements intended to come opposite.

  Conventionally, the assembly means is of the type requiring for mounting, on the one hand, the approach of the two opposing surfaces substantially parallel to themselves and, on the other hand, after their contact, a locking movement of at least one of the surfaces in one direction

  overall parallel to the plan they define.

  Evidemrment, disassembly is obtained by ordering

  aforementioned displacements in the reverse order.

  In general, to constitute the abovementioned assembly means: on the one hand, at least one of the opposing surfaces of the elements to be assembled is formed by the so-called front face of one of the opposite faces of a wall which comprises at least one minus a generally oblong cut and - on the other hand, the other counter surface carries for its part at least one member each able to be engaged in a cut by the defined approach movement, which member comprises at least one stop which, by a locking movement Also defined and meanwhile limited by the longitudinal extent of the cutout, is intended to bear against the face of the wall opposite to that receiving the

surface bearing the said organ.

  To limit the risk of disassembly, it directs the cutouts and anchoring members of Lanyard such that the locking movement is effected, from top to bottom when

  the posts are erected vertically.

  This solution gives good results but it excludes the lifting of the structural assembly by their elements

interconnect amounts.

  In addition, the assemblies thus designed are criticized for being

  in fact only partially removable.

  One of the results that the invention aims to obtain is an assembly device which, while allowing the construction of assemblies of the aforementioned type which are completely removable, remissed to the disadvantages of conventional assembly devices that is to say hinders the risk of accidental dismantling. For this purpose, the subject of the invention is such an assembly device, characterized in that: on the one hand, at least some of the assembly means presented by the structural elements comprise at least one additional abutment carried for, substantially at the end of the engagement of the fastening abutment that has the anchoring member against the front face of the wall through which it passes, engage at least by approximation of the opposing surfaces against at least one stop complementary opposing an opposite movement of clearance of the abovementioned abutment abutment of the anchoring member and, - secondly, at least some of said structural elements comprise at least one detachable locking means opposing any movement of spacing of the opposing surfaces tending to induce the release of additional abutments and complementary abovementioned. It also relates to the structural assembly provided

of these devices.

  As it appears in the drawing, the structural elements 2, 3, 4 that is to say the elements 3, 4 of bracing and interconnection and the posts 2 are assembled together by means of assembly 6 of the type to hanging, interposed between surfaces 7 to 10 elements

  which are intended to come in support and / or in contact.

  This has been mentioned, by means of hooking assembly, it will be understood a means requiring for mounting on the one hand, the approach of two surfaces 7, 8 and 9, 10 antagonists substantially parallel to themselves and, d on the other hand, after their contact a locking movement of at least one of the surfaces in a direction generally

  parallel to the support plan they define.

  In known manner, to constitute each assembly means: - on the one hand, at least one 7, 10 of the surfaces 7 to 10 antagonists of the elements 2, 3, 4 to be assembled is formed by a 7, 10 opposed faces 7, 11 and 10, 12 of a wall 2a, 3a which comprises at least one cutout 13 generally oblong and - on the other hand, the other counter surface 8, 9 carries at least one member 14 each to even to be engaged in a cutout 13 by a displacement of said opposing surfaces 7, 10 and 8, 9 substantially parallel to one another 7, 10 to the other 8, 9, which member 14 comprises in turn two stops 15, 16 of which a first 15 said hooking and intended to come generally bearing on the face 11, 12 said anterior wall opposite to that 7, 10 receiving the surface 8, 9 which carries the body 14 and a second said stop 16 intended to bear on the edge 17 of the cutout 13 for limiting a sliding displacement of an opposing surface on the other, engage the

  first stop 15 facing the face 11, 12 concerned.

  As it appears, preferably, one 7, 10 of the two opposing surfaces 7, 10 and 8, 9 comprises at least two cutouts 13 substantially aligned and the other surface 8, 9 two anchoring members 14 arranged to cooperate simultaneously with

the said cuts.

  Preferably, each post 2 comprises a plurality of cutouts 13 substantially aligned and regularly spaced in particular in a pitch P, which constitute at least one row parallel to the longitudinal axis of the post and preferably

two rows.

  Note that, conventionally but not limitatively for the invention, each anchoring member 14 is constituted by a tab formed by cutting and folding a fraction of the

wall 14a which carries this member 14.

  To constitute the device. assembly device according to the invention, ie the device in order to obtain the results advanced further: on the one hand, at least some of the assembly means that present the structural elements 2, 3, 4 comprise at least one additional abutment 18 carried for substantially after the engagement of the abutment stop 15 that the anchoring member 14 has against the front face 11, 12 of the wall 2a, 3a that it cross, engage at least by approximation of the opposing surfaces 7, 10, and 8, 9 against at least one complementary abutment 19 opposing a reverse movement of disengagement of the abutment abutment 15 above the body of anchoring 14 and - on the other hand, at least some of said structural elements comprise at least one detachable locking means 22, 24, 25, 20.26 opposing any movement of spacing of the opposing surfaces 7, 10 and 8, 9 tending to induce the release of additional and complementary stops 18 , 19 above. According to the invention - on the one hand, each attachment stop 15 is arranged and shaped to co-operate with the anterior face of the wall through which the anchoring member passes, to hinder any separation of the opposing surfaces at its level. nevertheless allowing in a plane substantially perpendicular to said surfaces and generally parallel to the longitudinal axis of the cutout 13 at least a slight angular movement about an axis passing through the point of contact of this stop with the aforementioned anterior face, this movement being of at least sufficient amplitude to disengage the additional abutment 18 from the complementary abutment 19 by inclining at least one of the opposing surfaces relative to the other and, secondly, the removable locking means consist in at least one releasable stop 22, 24, 25, 26c which hinders the relative angular movement of the opposing surfaces, one by

report to the other.

  In a preferred embodiment, on the one hand, the additional abutment 18 is constituted by a protrusion protruding from the surfaces 8, 9 of the opposing surfaces 7, 10 and 8, 9 which carry an anchoring member 14 and on the other hand, the complementary abutment 19 is formed by the edge 19 of the cutout which is opposite to that 17 of the said cut which cooperates with

the anchoring member 14.

  For example and therefore not limited to the invention, the boss 18 is obtained by local stamping of the wall 14a.

  which carries each opposing surface 8, 9 concerned.

  In order to constitute the blocking means 22, 24, 25, 26c: at least some of the ends 3b, 4b of bracing elements 3 and / or of interconnection elements 4, on the one hand, are provided with so-called lateral 8 and extreme 20 bearing for support on two edges 7, 21 perpendicular to a pole 2, the lateral bearing 8 constituting precisely one of the opposing surfaces 8, 9 carrying an anchoring member 14 and, on the other hand, have at least two other bearing surfaces 9, 22, one of which is said to be contralateral which is opposite to the aforementioned lateral bearing surface 8 and the other of which is said radial 9 which lies in a plane P1 generally perpendicular to the longitudinal axis 23 of the element in question, this bearing surface 9 also comprising at least one of the aforementioned anchoring members 14 carried by some of the opposing surfaces, - the ends 3b, 4b of the elements 3, 4 which are devoid of bearings of support say extreme 20 and lateral 8 against songs 7, 2 1 of a post 2 comprise, for their part, at least one end face 24 bearing against a contralateral bearing surface 22 of an element and at least one other lateral face bearing against a radial bearing surface 9 of the same element, 3 elements 3, 4 of bracing and / or interconnection which are provided with support faces 24 and said extreme lateral respectively against contralateral surfaces 22 and radial 9 elements 4 are also provided with at least one so-called locking range 25 oriented on the one hand to each receive the support of a surface 26c of the end 26b of at least one part 26 interposed including elastically between two parallel spacing elements and / or interconnection and located in a plane substantially perpendicular to the posts and, secondly, so that the action of this piece tends to press each so-called lateral face 10 of each element concerned against the radial bearing 9 facing

of which it is located.

  It is therefore understood that the means 22, 24, 25, 26c blocking essentially implements cooperating surfaces 22, 24, 26c spacer elements 3, interconnection 4 and

one piece 26.

  According to the invention, the opposite ends of the interconnection elements 4 each have a radial surface 9 and a contralateral surface 22 while the opposite ends of the spacer elements 3 each have a so-called lateral face 10 and an extreme face each respectively of support against a radial range 9 and contralateral 22 of a

interconnection element 4.

  According to the invention, on the one hand, the radial 9, contralateral 22, lateral 8 and extreme 20 radial surfaces consist of at least some of the substantially plane faces of a part 27 of a certain length LI and which has three wings 28 , 29, 30 including a medial wing 28 which carries laterally and substantially perpendicular to the plane that it forms two lateral wings approximately parallel but oriented in opposite directions and, secondly, this piece 27 is associated with the end 3b, 4b of each spacer element and / or interconnection element 3, 4 by one of the opposite faces of a

lateral wing 29, 30.

  Those skilled in the art are able to determine the length L1 of each piece 27 having the radial, contralateral, lateral and extreme bearing surfaces so as to ensure

  proper seating between the elements.

  The aforementioned part is for example welded at the end of

elements concerned.

  Characteristically for the invention, on the one hand, each so-called locking surface 25 is constituted by that of the internal faces of an element which is opposed to at least one antagonistic surface of the element which it must maintain in against another opposing surface and on the other hand, the wall of the element comprises at least one cutout not only allowing engagement of the end of the locking piece so that the end surface 26c of this element slides against the locking range but also ensures the elastic retention of the end 26b of the

said piece 26 in this position.

  Each locking piece is intended to extend between two opposite locking surfaces, ie two spans located on opposite spacer or interconnection elements and, although this does not appear in the drawing, is of length L2 substantially greater than the distance

  D which separates the two aforementioned locking surfaces.

  When the element which has the locking surface is substantially tubular, for example, of rectangular cross-section, the locking surface is cut off

  in two substantially perpendicular faces of the element.

  Also the clearance is arranged in the element so that the mounting of the locking piece is from top to bottom, ie in the direction of

  locking of the structural elements assembled together.

  The assembly device according to the invention is of course optimal when at least four columns are assembled with at least two groups of elements on the one hand, each composed of two bracing elements and two interconnecting elements and , on the other hand, which are arranged in two

  parallel plans relatively distant.

  In a configuration shown in the drawing, each locking piece interposed between locking surfaces, for example located on two opposite spacer elements 3, plates the said extreme lateral faces of each of these elements, each against a range.

  radial 9 of an interconnection element.

  Advantageously, said locking piece thus hinders the release of the locking members that

  have the lateral faces and bearing radial bearing.

  Similarly, in this configuration, the end faces 24 of each spacer element 3 each rely on a contralateral surface 22 of an interconnection element and thereby also hinders the release of the anchoring members which bind a span. side of a singing interconnection

of a post 2.

  The person skilled in the art is able to determine the assembling games of the structural elements between them by the implementation of

of the indicated means.

  Preferably, the wall of the posts has substantially at the cutouts 13 resiliently deformable corrugations in a direction generally perpendicular to the edge which carries them and these corrugations are of such magnitude that it cancels the assembling games at least at the level of

  each additional stop 19 of the cuts 13.
