Description

A buckle is presupposed, consisting of two rectangular frames entering one another, which, when Closing the belt passing through them, slide one over the other, forming a friction closure. Such a device of a buckle is supposed to achieve the following advantages: when applying a buckle in belts experiencing the effect of tensile strength, the possibility of replacing the skin with a cotton band of appropriate density and strength, considering the purpose of the belts; possibility to make any adjustment of the belt tightening; The smooth surface of the buckle in a closed form allows its use in a dressing gown and on other objects where it is undesirable to have sharply protruding metal parts of the buckle (pegs).

In FIG. 1 shows a view of a buckle on a closed belt; FIG. 2 is a horizontal section of FIG. I; FIG. 3.3 and 4, 4-part frames; FIG. 5 and 6 illustrate the relative positioning of the frames.

A frame 2 is attached to the end of the webbing 6. Another frame 3 is attached to a separate piece of the webbing 4 in such a way that by attaching the frame to TecbPie 4 there are two free non-arvic end lengths. The short end of the braid 4 is attached to the end of the braid 6, and the long end is left free and serves to open the yarn. The piece of tape with the frames attached to it is a belt for grasping and pulling the object. A belt is manufactured as follows. The free end of the band 1 is circled around the object to be tightened. Then the end of it is passed through both frames 2 and 3, after which, opening frame 3 from frame 2, bend the side of frame 3 with the end of braid 1, bringing it under the bottom of the side of frame 2. Having tucked the end of the braid 1, frame 3 impose guide ribs on frame 2 and tighten the end of the band I. Shrinking the end of the string 1 to the required limits, transfer it over the frames, fill it and tighten it under the belt loop, in order to eliminate the breaking of the buckle.

To unfasten the buckles from under belt loop 5, the tucked end of the band 1 is loaded, then the frame 3 is easily pulled off the frame 2 for the free end of the band 4, and the buckle, unfastening, releases the end of the band 1.

The proposed buckle is intended for use, for example, in luggage straps, along sling, suspension straps for tightening sleeves in leg prostheses, etc.

The subject matter of the invention.

A friction gate strap, characterized in that it is made of two rectangular frames 2 and 3, which slide along one another as the belt passes through them.
