Clamp crack Description

The invention relates to an insert for a clamping device and to such a clamping device, in particular for fastening cladding to building elements.

Such clamps are well known and are often used to attach various types of cladding to double-T beams and similar supports and similar building elements. The known clamps have the disadvantage that complex substructures are required for the cladding of the aforementioned components, where dimensional accuracy requirements must be met. For cladding that only has a functional character, up to

The clamps are now made from the cladding material on site or from another material, such as wood. This type of procedure has the disadvantage that it is very time-consuming and requires a high level of precision, as the clamp must be cut to the exact millimetre for the component in which it is to be used. If the deviation from the nominal size is too great, the clamp either cannot be fitted at all or no clamping effect is achieved.

It is therefore an object of the present invention to further develop a clamping device of the type mentioned at the outset in such a way that a clamping device of simple construction is created.

This object is achieved according to the invention in that the insert has a base body having at least one side element, and in that at least one side element has an insertion part and a stop part, via which the insert can be arranged in a positionally positioned manner in a central part of the clamping jaw, and in that the insert has at least one insertion bevel.

The measures according to the invention advantageously form an insert for a clamping device that is easy to manufacture, as well as a clamping device of this type, which is characterized in that it can be constructed from components that are easy to manufacture. The use of an elongated middle part, which according to an advantageous development of the invention is made from a commercially available C-profile, makes it easy to adjust the clamping device to the length required in each case by cutting the middle part of the clamping device to the appropriate length.

The inserts of the clamping jaw according to the invention, which are designed with at least one insertion bevel, advantageously ensure that the clamping jaw is securely clamped in the component interacting with it, in particular a double-T beam or a double-T support.

An advantageous further development of the invention provides that the elongated middle part of the clamping device according to the invention is less rigid than the insert or inserts arranged at at least one of its ends, and that the clamping device according to the invention is made to an oversize. When the clamping device according to the invention is inserted into the component assigned to it, the middle part is then deformed, so that a strong clamping effect is achieved.

A further advantageous development of the invention provides that at least one insertion bevel of the insertion of the clamping device according to the invention has a toothing. Such a measure has the advantage that the toothing counteracts the pulling out of the clamping device inserted into the component and increases the pulling force required to pull out the clamping device according to the invention. The clamping device according to the invention is therefore characterized by a high level of security against unintentional pulling out.

Further advantageous developments of the invention are the subject of the subclaims.

Further details and advantages of the invention can be found in the embodiment described below with reference to the figures. They show:

Figure 1 shows a clamping device, generally designated 1, which is essentially divided into an elongated middle part 2 and two inserts 3a, 3b inserted into this middle part 2. The middle part 2 of the clamping device 1 is preferably made from a commercially available C-profile. Such a measure is not only characterized by its cost-effectiveness. Rather, it is also possible to adapt the clamping device 1 in a simple manner in terms of its axial extension to the component in which it is to be inserted by simply cutting the middle part 2 to the appropriate length. This can be carried out quickly and easily in an advantageous manner using commercially available tools.

An insert 3a, 3b is arranged at each of the two ends 2', 2" of the middle part 2 of the clamping device 1. However, it should be mentioned at this point that the provision of two inserts 3a, 3b is not absolutely necessary. Rather, it is sufficient for a number of applications that the clamping device 1 described only has an insert 3a, 3b at one of its ends ²¹ , 2" and the other, now free end 2', 2" is positioned in a known manner, e.g. in a recess or in an insertion opening, on one surface of the component when the clamping device 1 is inserted into this component.

Preferably, the middle part 2 is made of a material that is less stable against deformation than the two inserts 3a, 3b. This allows the described clamping device 1 to be made to an oversize. When the clamping device 1 is inserted between the two surfaces of the component that delimit the opening to be covered, the middle part 2 of the clamping device 1 is then at least partially elastically deformed, whereby an extremely strong clamping effect is advantageously achieved.

The inserts 3a, 3b shown in Figures 2 to 5 have a base body 3 with two side elements 4a', 4a" and 4b ¹ , 4b", each of which has a guide part 5 and a stop part 6. The guide part 5

serves to insert the side elements 4a ¹ , 4a", 4b', 4b" into the middle part 2 of the clamp 1 and to secure the position of the inserts 3a, 3b therein. The stop part 6 of the side elements 4a'-4b" ensures that the inserts 3a, 3b are arranged in the middle part 2 of the clamping device 1 so that they cannot be moved in the axial direction towards the middle thereof, in such a way that they counteract any further insertion of the side elements 3a, 3b into the interior of the middle part 2 - even when a corresponding force is applied when inserted. It is advantageous here that the middle part 2 of the clamping device 1 - as shown in Figure 1 - has two inwardly bent edges 2a and 2b, which on the one hand guide the two outer surfaces 5' of the insertion parts 5 resting on the inner wall of the middle part 2 of the clamping device 1 and on the other hand interact with the stop part 6 of the side surfaces 4a, 4b of the inserts 3a, 3b.

Each side element 4a', 4a", 4b', 4b" of the clamping device 1 has an insertion bevel 7 on its side opposite the stop part 6, which is designed to be straight, curved or arcuately rising from its first end T to its second end 7", wherein the axial extension of the clamping device 1 between the second ends 7" of side elements 4a ¹ , 4a" or 4b', 4b" lying opposite one another in the longitudinal direction determines the effective length of the clamping device 1. The design of the insertion bevels 7, which rise from the first end T to the second end 7", makes it easy to replace the described clamping device 1 in the component assigned to it.

Preferably, it is also provided that the insertion bevels 7 have a toothing 8 at least in the region of their second ends T , which causes the insertion bevel 7 to press via its toothing 8 against the surfaces of the component into which the clamping snap 1 is to be inserted and thus cause an increased pull-out force, which secures the clamping snap 1 inserted into the component against unintentional withdrawal from the assembled state.

Preferably, it is also provided that each insert 3a, 3b has a stop surface 9 and/or projections 10 which prevent the clamping jaw 1 from being pushed too deeply into the opening to be covered, which is delimited by the corresponding surfaces of the component.
