According to one embodiment of the invention, there is provided a zipper lock where the object of compression can be any part of the zipper. The object may be the zippering of the zipper, or the gap between the teeth, or the compression may be directed to the edges of the tooth, or together with the toothing and the zipper textile straps, or even the zipper textile straps exclusively.

T: 20

The zipper lock according to the invention is of a single construction and * assembly; fold and consists essentially of two parts: a lock body and a pull-on • «· •: · ·: mesh. The bracket formed in connection with the lock body allows the handle to be •: · · fixed. The handle portion may be formed such that there is a space underneath and between the locking frame roof plate: where a portion of the pull loop is positioned when the pull loop is threaded around the lock portion of the lock body. The san chaos may also be formed as a rail, having a horn-like part.,.: A thickened part and a narrower rail part which adjoins the roof of the lock body; '. leaf. The puller loop is then configured to be clamped and the clamping portions press into the rail portion on both sides thereof and the loop portion is substantially around the thickened portion. The zipper lock body is provided with a plunger slot / threading point for the puller at the handle portion so that the puller cannot fall out when the zipper is in place in the lock body. The threading slot / threading point is disposed substantially outside the roof panel, preferably on the backside of the lock relative to the direction of travel of the lock zipper, i.e. horizontally viewed from outside the stern of the roof panel.

According to the invention, the pulling of the pull by the lock is primarily prevented by the insertion of the zipper into the lock, and according to a preferred embodiment of the invention, the zipper substantially closes the pulling gap formed between the tail portion of the locking member and the roof plate. There is no need to bend the buckle during assembly of the buckle, since the puller is slidable between the buckle body and the buckle with the remainder of the buckle extending a distance from the rear end of the buckle, i.e., . The tail portion of the handle extends with the lock in place substantially adjacent to the zipper so that the puller cannot fall out of position.

According to a preferred embodiment of the invention there is a zipper lock body: •: *. 20 a runner-shaped bracket formed with a threading point · · for the puller so that the threading point extends beyond the lock body, · ”. that the zipper in the lock body prevents the puller from falling off;; ··. ' but the puller can be easily slid in before inserting the zipper ·; ···. The bracket portion is thus formed as a rail, the bracket portion comprising an outer thickened portion, which at the front of the zipper extends to the lock body and at the rear forms a peripheral portion of the threading slot and the rail portion is substantially narrower than the thickened portion. movable and to which portion the puller is threaded through the slide point. This embodiment of the invention has a pulling portion of the puller; 1 ''; The 30 rail sections are shaped so that the puller cannot fall out of its position in the traction. with the chain in place on the zipper lock body. The body bracket and puller 5 110753 are shaped such that the pulling point of the puller formed between the lock body and the tail portion of the bracket extends close to the zipper so that the puller remains engaged with the lock body while the zipper is in the zipper lock.

According to a further advantageous feature of the invention, the locking zipper locks are preferably prevented from being pressed against the zipper, and the locking force required for the zipper lock, the snap of the puller to the locking position and the locking position can be adjusted. muo-10 by tapping or utilizing the stiffness and deflection of the zipper outside the buckle of the buckle, or by the selection, stiffness and deflection of the material of the zipper itself. It is easy to adjust the buckle lock for different purposes and chain types by shaping, for example, the pull handle or other parts of the buckle as needed. By moving the locking points, a solution can be obtained from the fully locking version 15, in which the locking is maintained only up to a certain desired limit. In this case, the zipper will not break under heavy load, but will give up when the load is too high. According to a further advantageous feature of the invention, the locking is mainly prevented between the locking walker of the puller retainer and the lower cover of the lock on the outside or outside of the cover plate (top cover) as is usually done.

The zipper lock according to the invention is also suitable for use with a restraint • · · •: · · | in non-stop zipper locks.

The zipper lock according to the invention is particularly reliable because the puller »· · is released and is generally only removable when the toothed portion of the zipper itself is not threaded into the lock. According to some preferred embodiments of the invention, the release of the carrier may also be ensured by bending the brace or; ; * · By designing the bracket / rail. A similar effect can be achieved by shaping or fitting the puller or • · I · 30 frame members or the frame member / bracket / rail portion, as desired.
