DESCRIPTION:
BRIEF SUMMARY
The present invention concerns a system for assembling at least two parts along their facing flat-shaped surfaces, and is more particularly intended to be applied in the field of furniture, for connecting two horizontal panels forming a working surface to a single supporting sub-frame.
The latter can of course be also attached to a single working surface under equivalent conditions.
Devices are already know enabling these functions to be partially fulfilled. Thus, European patent EP 0 458 042 concerns a rotating locking system arranged under table tops and cooperating with pegs situated on the upper part of the supporting stands. Each stand may be either entirely situated under a single panel or distributed between two contiguous panels, of which the opposite edges then come into contact with each other.
The locking plate of the stand is provided with buttonholes cooperating with the said pegs and pivots about a vertical axis, which implies that of necessity it only occupies a limited area. In point of fact, a plate with a circular shape and having peripheral locking means designed to be applied to the edge of the table top must have a reasonable diameter so that it does not project, for obvious economic and technical reasons. Consequently, this system can only be applied in the region of angles, cooperating with conventional supports with a small section.
A system of this type additionally involves the sequential assembly of a first support, followed by a second, while the locking controls of each of the supports are not easily accessible since they are situated under the lower surface of each panel. From the point of view of assembly, the installation of supports under a single horizontal panel or under two horizontal panels attached by their transverse edges is equivalent.
A non-rotating system is disclosed in the U.S. Pat. No. 2,609,264. This system includes male elements designed to cooperate with slits, the first being situated on the sub-frames whereas the second are arranged under the panel. However, locking rods provided to attach the sub-frames to the said panel have a localized action, i.e. they are applied individually for each male element/slit couple
When the panel forming the working surface of the desk is positioned on the sub-frames supporting it, it is thus necessary to inspect all the angular areas so as to lock the connections sequentially.
The same applies to the system disclosed in U.S. Pat. No. 2,987,262, which discloses an even more basic system. The elements for fixing the sub-frames to the panel are two in number, one being applied in a vertical direction while the other acts in a horizontal manner. Their interaction enables the panel to be locked onto the sub-frames. The operator responsible for assembly must also successively lock each connection in a manner which is moreover not very practical since the operations are to be carried out under the said panel.
The subject of the present invention on the contrary enables a sub-frame supporting one side of a panel or the two sides of two attached panels to be fastened in a single operation.
In addition, simultaneous locking of the sub-frame to the panel is carried out very easily, and can be achieved outside the volume covered by the said panel, in a single manoeuvre by the operator.
Similarly, simultaneous unlocking of all the fastening points along one or two edges (in the two aforementioned cases) is possible simply by carrying out a manoeuvre opposite to the preceding one.
The main objective of the invention is hence to simplify as much as possible the assembly and disassembly of a sub-frame to one or two horizontal panels.
To this en, in a very general manner, the invention consists of a system for assembling at least two parts along their facing flat-shaped contacting surfaces, the first comprising at least two perpendicular studs provided with a groove, each stud being able to be accommodated in an orifice in the second part, with which is associated a movable device parallel to it, on the opposite side to the surface facing
