The invention relates to a pincer-like holder clamp for braces, each consisting of a rigid and elastic clamping part having clamping jaws, one end of the rigid Clamping part is bent back U-shaped to form a resilient bearing that the closing or The clamping lever of the clamp carries the end opposite the handle on the clamp spring serving elastic clamping part acts.

In a known holder clamp of this type, the use of the U-shaped bracket part is attached Bearing eyes indispensable, which protrude over the outward-facing surface of the same and have an undesirable abrasive effect. You cannot use the bearing of this well-known clamp either in the relevant bracket leg, otherwise it is too thick and not the indispensable elasticity would exhibit. Furthermore, the pivot bearing for the tension lever is also in this known retaining clamp arranged near the point of attachment of the clamping jaws, so that the clamping spring hardly has any effect can come and the entire spring force can be applied by the U-shaped bent back bracket got to. In addition, in this known design, the tensioning lever from above on the relevant Leg of the U-shaped bracket or U-shaped bent back end of the rigid clamping part hangs up, so forms projecting parts with its wheels.

The invention avoids these disadvantages, in that the U-shaped bent back end of the rigid clamping part is rolled inwards to form the bearing and that the hinged to the bearing and locking and tensioning levers provided with two adjacent longitudinal slots in the closed one Position of the clamp partly encompasses the exposed part of the bearing pin from the outside and partly that inwardly rolled end of the clamping part surrounds from the inside.

This creates a smooth top surface when the clamping lever is closed, which provides great stability and secure holding of the clamping lever guaranteed. This creates a retaining clip, which is a special one smooth surface, so no sharp protrusions on the top surface.

The construction according to the invention also advantageously differs from another known holder clamp, belong to the storage at right angles upwardly bent flaps, which for a protection of the Garments, however, are disadvantageous. The same is true of another known clamp, in which the clamping lever is directly on the corresponding

accordingly strongly resilient U-shaped bent back section of the rigid clamping part, the itself carries the jaws in question, acts, so there is no separate spring. Here, the clamping lever is pushed onto the bearing axis with a certain amount of curling, but

ao does not have the desired smooth surface because of the above-mentioned protruding flaps on the sides. Exemplary embodiments of the invention are described in more detail below with reference to the drawing. In this shows

F i g. 1 the holder clamp seen from the side and partially in section,

F i g. 2 sections of a modified design with a special adjustment option for compensation the weakening of the clamping spring and

Fig. 3 for the adjustment of the design according to F i g. 2 essential parts in plan view.

The in F i g. The rigid clamping part 1 shown in FIG. 1 is reinforced by two beads 2 running in the longitudinal direction and has a resilient end 4 which is bent back upwards in a U-shaped manner around the belt eyelet 3 and which in two spaced apart, inwardly rolled tongues 5 expires, which is a bearing for form the clamping lever of the holder clamp. In the bend of the clamping part 1 is a curved leaf spring formed elastic clamping part 6, 7 inserted, which is also wrapped around by the eyelet 3. The short arm 7 of the clamping spring rests against the clamping part 1 and acts as an unlocking element for the Holder clamp. The clamping spring is bent open from the clamping part 1 to prevent lateral displacement Tongue 8 secured, which engages in a corresponding recess of the clamping spring arm 7. the Tongue 8 strikes against eyelet 3 and thus holds clamping parts 1, 6 and 3 together.

The closing or tensioning lever 9 is provided with two adjacent longitudinal slots on the bearing, so that there are three adjacent lobes

result, with which the lever 9 partly the exposed Part of the bearing pin 10 engages around from the outside in the closed position, partly the rolled inward Surrounds the end 5 of the rigid clamping part 1 from the inside. Touch in the embodiment shown the two outer lobes of the lever 9, the rolled ends 5 of the clamping part 1, while the middle The rag encompasses the central exposed part of the hinge pin from the other side. The ends of the two outer tabs of the lever 9, with which it acts on the elastic clamping part 6, are bent back in the shape of a hook, which means that when the clamping lever 9 is closed and pressed together the clamping jaws 11, 12 due to the curves of the hook-shaped end only have a low specificity Surface pressure of the clamping spring 6 results.

The holder clamp described is composed of substantially rectangular stamped parts without protruding Flaps or the like together and can therefore be manufactured with only a small amount of punching waste.

The construction creates a clothing-friendly, smooth exterior of the closed clamp by protruding parts and sharp edges are avoided. The U-shaped bent back end 4 of the rigid Clamping part 1 and the elastic clamping part 6 »5 represent two springs connected in series. It is thereby given a large area of the elastic clamping effect, so that the holder clamp through Overstressing with the consequence of permanent deformation of the spring parts their elastic properties can't lose.

In order to be able to counteract a gradual decrease in the clamping effect, in the embodiment according to FIGS. 2 and 3, the clamping spring 6 is a lobe-shaped support part 15 bent up, the end of which by a straight section of a self-contained, rectangular wire bracket 16, 17 is supported. In this way, the hook-shaped bent back works See the end of the closing or tensioning lever 9 over the support part 15 and the bracket 16,17 on the elastic Clamping part 6. The degree of bending of the tab-shaped support part 15 determines the distance between the axis of rotation of the clamping lever 9 and the clamping spring 6. This distance and thus the clamping force The clamp can be enlarged by moving the straight section or bolt 16 of the bracket moves along the corrugated section of the clamping spring with HiKe of the bracket section 17, which is accessible through an opening 18 in the U-shaped bent back part 4.
