(54) CLAMP FOR TEMPLATES

(57) The invention relates to mechanical engineering, in particular to curtain clamps, and can be used in devices for fixing panels. The purpose of the invention is to enhance functionality and increase reliability. The clamp contains two supporting branches 1 and 2,

interconnected with the possibility of moving one branch relative to another. The first support branch 1 is made in the form of a plate with parallel sides, on the lower outer side of which there is a transversely curved and inclined supporting platform 4. The second support branch 2 is made in the form of a plate with two shoulders in its upper part, on the lower edge of which the sides are made of a protrusion 6, and on the inside they are grooved 7. The shoulders of the second support branch 2 cover the sides of the first branch 1 with the possibility of free sliding of the second branch 2 relative to the first branch 1 until the lower edge of the second branches 2 on the supporting platform first. 6 Il.

The invention relates to clamping devices for fastening panels, hanging curtains, and the like.

The purpose of the invention is to expand the functionality of use and increase reliability during operation,

Figure 1 shows a clip for curtains, front view; figure 2 is the same, side view; on fig.Z - the same, top view; figure 4 - clamped material curtains without finishing the upper edge, side view; Fig.5 - the same, with a thickening of the upper edge, for example, with the help of stitched flexible cords in Fig.6 - the same, stitched folded in several layers of curtain material.

The clip for the panels contains support vervy 1 and 2, interconnected with the possibility of moving one relative to another. The branch 1 is made in the form of plates with parallel sides, on the lower outer side of which there is a transversely arranged groove 3 and a supporting platform 4 inclined relative to the longitudinal axis, the angle a being 5-10 °. The support branch 2 is made in the form of a plate with two shoulders 5 in its upper part, on the lower edge of which there is a protrusion 6 on the outer side and corrugation 7 on the inner side. On the upper back side of the branch 1 a head 8 with a neck 9 dl can be made install the clamp in the guide groove of the supporting rod of the eaves. In the case of another design of the rod of the eaves or using the holder for other purposes, the implementation of the above connection of the clip to the bearing rod may be different.

The clamp works as follows.

The support branch 2 for the protrusion 6 is lifted from position A to position B, as shown in FIG. This is the edge of the cloth between the supporting platform 4 and the relief surface 7 of the branch 2. Under the action of the weight of the cloth or under the action of additional}, the load of the branch 2 drops a little along with the cloth, since the friction between the branch

2 due to the corrugation of its surface is much larger than the adhesion of the cloth with the surface of the supporting platform 4, which is made smooth, as a result

additional lowering of the branch 2 is the jamming of the panel, and consequently, its safe holding.

In the event that a smoother material is used (e.g. silk), the amount of friction between the surfaces is no longer sufficient to hold the silk cloth. In this case, a thickening of the upper edge of the sheet is applied according to the method depicted in FIG. 5 or 6. This panel is fixed as follows. Lift to branch 2, insert branch 1 into the groove 3 of branch 1, the thickened edge of the panel and lower branch 2 until the panel is clamped. In this case, the cloth will not be able to jump out.

from the clamp, because the thickened edge cannot be pulled between the ends of the first and second support branches.

Expansion of functionality is achieved by securely fastening panels made of any material. The clamp is easy to use and can be made, for example, from metal or polyethylene.

Claims (1)

Invention Formula A clip for panels containing two supporting branches interconnected with the possibility of moving one branch relative to another, characterized in that, in order to expand functionality and increase reliability, one support branch is made in the form of a plate with parallel sides, having at one end a semi-cylindrical a bend and an inclined support platform, the second branch is made in the form of a plate with two shoulders on one end, perpendicular to the protrusion directed away from the first branch on the other, and corrugation m on the opposite ledge side, with the shoulders of the second branch embracing the first branch with the possibility of sliding the second branch relative to the first fully ribbed into the supporting area of the first branch and forming a closed cavity bounded by the bend of the first branch and second branch.
