BRIEF SUMMARY
DESCRIPTION

The invention relates to a locking clip for fixing the edges of partition wall panels of the kind where two plasterboard panels are held spaced from each other by cellular transverse ribs.
In order to erect and fix these lightweight partition wall panels it is known from FR 2 634 239 to connect the walls together by connecting pieces which penetrate on both sides into the interspaces between the plasterboard panels so that the wall edges are fixed relative to each other. At the floor the partition wall panels are fixed by means of U-shaped profiled rails in to which the lower panel edge is turned and then screwed firm. At the side walls U-shaped profiled rails are likewise used into which the partition panel is inserted sideways. At the ceiling the fixing is by means of angular sections which are fixed from outside on to the top edge and are then screwed to the ceiling.
This known method of fixing using various profiled rails is very time-consuming and therefore expensive per fastening point. A further disadvantage is that the fixing sections at the ground and ceiling remain at least partially visible and must then additionally be covered for aesthetic reasons.
The object of the invention is therefore to provide a locking clip with which the edges of the aforesaid partition wall panels can be connected together quickly and simply and can be fixed to the side walls as well as to the floor and ceiling. Furthermore these clips should be easy to manufacture from plastics material so that the costs for each fixing point can be reduced.
This is achieved by the locking clip indicated in claim 1 which is characterized by the following advantages: The clip can be used equally well for fixing the wall panels together and for fixing the wall panels to the side walls and ceiling. The clip which is composed of a casing and pressure member is pressed at each proposed fixing point with the casing into the space between the plasterboard panels and when the pressure member is engaged is brought in front of the edge of the adjoining wall panel. The detent engagement is then released by pressing the retainer spring sideways so that then as a result of the resetting force of the sprung arms the pressure member slides halfway into the opposite space so that the wall edges are secured relative to each other.
Plastics panels must be fixed at the proposed fixing points on the side walls and ceiling, these panels being provided with rectangular recesses into which the pressure members can engage as the panel edge is swivelled past. These fixing plates are preferably dimensioned widthways so that their outer edges just close with the plasterboard panels.
Further details of the invention are given in the sub-claims and will now be described in detail together with their advantages with reference to an embodiment of the invention illustrated in the drawings in which:
FIG. 1 shows the pressure member of the locking clip according to the invention in front view;
FIG. 2 is a cross-sectional view of the pressure member taken along the line II--II of FIG. 1;
FIG. 3 shows the pressure member in plan view;
FIG. 4 shows the casing of the locking clip according to the invention in front view;
FIG. 5 shows the casing in cross-section along the line V--V of FIG. 4;
FIG. 6 shows the pressure member in plan view;
FIG. 7 is a side view of a pre-assembled locking clip;
FIG. 8 shows the same locking clip in cross-section along the line VIII--VIII of FIG. 7;
FIG. 9 is a side view of the locking clip with the pressure member fully pushed in;
FIG. 10 shows the same locking clip in cross-section according to the line X--X in FIG. 9;
FIG. 11 shows a locking clip with the pressure member fully pushed in the edge area of a partition wall panel before disengagement of the pressure member;
FIG. 12 shows the same locking clip installed and after disengagement of the pressure member;
FIG. 13 shows the partition wall panels during erection in a room;
FIGS. 14 a) to c) show the operating sequence when locking the partition wall panels in the side ar
