The main patent relates to a fabric clamp for Suspenders and the like, consisting of two rigid, double-lever-shaped, articulated interconnected and by a U-shaped leaf spring in the open position spread legs, the support tape facing ends are bent inwards, so a pivot bearing for the approximately oval The cross-section of the locking web determining a space that is to be fastened to the carrying strap, wherein the longitudinal axis of the oval cross-section runs transversely to the eye plane, with the features, that the directly adjoining the angled ends areas of the transverse web of the forming the only connection between the two legs, with their ends pointing inwards Projections of the leg spring formed from plastic embedded also in the projections are held and that on the inner surface of one leg before it is bent inward End of a rounded transverse channel is provided, in which the locking web of the lifting eye with one in the same Way rounded projection engages, while the opposite edge of the locking web is attached the curved inner surface of the other leg end is supported.

The ends of this fabric clamp are bent at an angle and the areas immediately adjacent the U-shaped bent leaf spring into the inwardly directed projections of the clamp legs injected. This assumes that the leaf spring is previously inserted into the injection mold during manufacture must become. The time required for this must be spent in addition to the spraying process, so that the manufacturing process for the individual fabric clamp is extended accordingly. Through this the tool itself is also more expensive and the insertion of the eyelet with the locking bar in the Recording room difficult.

The invention relates to an improvement of the main patent and consists in that the legs on the inner surfaces at both edges, in a manner known per se, one each forming the joint Bearing block and below the bearing blocks on their inner surfaces one after the other open, parallel to Grooves running along the longitudinal center plane of the clamps to accommodate the arms of a subsequently inserted Have U-shaped leaf spring, the arms of which in their inserted position on the inner wall of the Clamping legs are locked. According to a preferred further embodiment of the invention the ends of the leaf spring arms are preferably designed in a T-shape by means of edge incisions and

Cloth clamp for suspenders and the like.

for the T-shaped ends of the leaf spring arms a locking space is provided in each of the legs, the stirring cam are upstream. The projections of the legs arrive in the manner of a groove and

_ao spring engaged in the open position.

According to a further embodiment of the invention, the oval locking web has on the bearing blocks facing broad surface cams that initiate the opening movement when the lifting eye is pivoted the thighs support and limit. Below is an embodiment of the invention described in more detail on the basis of the drawing. In this shows

F i g. 1 the front view of the fabric clamp,

F i g. 2 and 3 show a longitudinal section in the closed and open position of the clamp,

F i g- 4 and 5 the leaf spring in the front and in the side view,
F i g. 6 the two clamp legs before their union,

7 shows the interior view of one of the clamp legs with the leaf spring being inserted and F i g. 8 shows the inside view of the other clamp leg with the leaf spring inserted.

The fabric clamp consists of two clamping legs formed from plastic 1 and 2, which are provided at their ends with clamping grip surfaces l ^a, 2 ^a. In the middle area, they each have a bearing block V>, 2 ^b , which are supported on one another in the manner of a joint. On each leg inner wall, two such bearing blocks l ^ö and 2 ^b are arranged at a distance from one another. In their foot area they have successively directed grooves 1 ^c , 2 ^C , into which the arms 3 ° of the U-shaped leaf spring 3 are inserted. The arms 3 ^{a of} the leaf spring 3 have lateral edge incisions 3 ^{b in} front of their free ends and are thus T-shaped. As a result-

You can approach them (Fig. 7) in the distance between the facing end faces of the bearing blocks t ^b , 2 ^b from above the inner wall of the corresponding clamping leg until they reach the level of the channels 1 ° or 2 ^{° C} , and now push them in parallel to the longitudinal center plane of the clamps into the insert position until they assume the position shown by the dashed line. In the area of the clamping surfaces t ^a , 2 ^a , a latching space l ^e , 2 ″ is arranged, in front of which two cams l ^f , 2 ^f are provided so that the ends 3 ^{a of} the spring 3 during the longitudinal displacement over these cams V, 2 ^f collapse into the latching space t ^e , 2 ^e so that they are locked in this position. The fabric clamp can also be taken apart by reaching under the spring arm end 3 ^a from the side and pulling it over the pairs of cams] /, 2 ^f removes.

At the other end of the legs 1, 2 are on the leg inner surfaces in the manner of tongue and groove for guiding the legs into each other penetrating projections I ^s , 2 ^ε and in the area in front of these bearing surfaces l ' ¹ , 2 ^h for receiving the oval crossbar 4 "of the Frame-like eyelet 4 is provided, in which the opposite edge areas of the transverse web are securely supported, i.e. latching, when the clamp is closed. Cams 4 ^b on the broad surfaces of the transverse web 4 ^a can facilitate and at the same time limit the closing and opening movement of the clamp legs 1, 2 (F i g. 3).

In the gripping surfaces t ^a , 2 ^a , longitudinal projections and recesses t ^d , 2 ^{d can be} provided, which interlock when clamped and thereby guide the two legs 1, 2 and relieve the spring 3.
