Description

The subject of the invention is a discontinuous fastener with a movable lock, which interacts with a number of plates connected in pairs, one of which has pins entering the second holes.

The proposed discontinuous fastener differs from the existing ones by the presence of a pin in the plate, which is inserted into the opening of the conjugate plate, and is locked when the fastener is closed by a mobile check installed on the latter.

FIG. 1 shows the appearance of the fastener; in fig. 2 and 3-plate fasteners on an enlarged scale; in fig. 4 and 5 locking lock.

The discontinuous fastener consists of a series of matching plates attached to each other, attached to the sides of different types of clothes to be closed.

Plate 1 (.fig. 2) has a locking mechanism mounted, consisting of a movable check 2 with a sprout 2 and a flat spring 3. A button 4 with a semicircular head is attached to the spring and the lock 5, which can enter into the hole 6 of the check 2, is fixed her position. Sod.r dressing-in 7 (Fig. 3) has an attached pin 8 with a recess in the upper part.

Pin 8 may enter the hole 10 of the first plate. Both plates have guide rails.

The lock for locking the plates shown in FIG. 4 and 5, consists of two parts, one of which (Fig. 4) has a guide groove 12, a guide protrusion 13 and an oblique groove 14; the other lock (fig. 5) has a guide groove 15. Both parts of the lock are interconnected by bolts: -.

When locking the fastener, i.e., when the lock moves along the guide of the rim, m plates, pin 8 of one plate enters the hole / Odrugoy, however, the process of the checks 2 falls into the oblique groove 14 of the lock, ., the course along the recess of the plate, presses button 4, lowers its pin-pin 5 and releases the cheg. Under the action of the oblique groove 14 of the lock of the check, it moves with its end into the recess 9 of the pin 8, thereby locking the plates.

The spring 3, released from the effect of the last lock, rises and the pallet g 5 locks the check.

A pin can be put into the plate to hang out the checks. There is an additional stopper for better holding the lock on the plates.

31 For the tightness of closing the zipper, rubber valves are located along the sides of the closable clothes, which, when the locks are clamped, come into contact with each other. The subject matter of the invention 1. A discontinuous fastener with a movable lock that interacts with a number of pairwise matching plates, one of which is provided with a pin entering the second hole, which is characterized by the fact that the hole plates are provided with a sliding check that comes in during fasteners in the recess in the top of the pin, passed through the through-hole of the mating pin with the pin. Clause I., characterized in that the check is provided with a process 2 communicating with a tapered lock guide, which moves the check with its movement in order to release or close the pin. pp 1 and 2, characterized in that the check is provided with an opening m, which serves for insertion of a fixing finger fixed on a flat spring mounted on a plate under the check. by pp 1-3, characterized in that the flat spring is provided with a button 4, which cooperates with the lock guide, in order to release the spring and release the checks. 2. The form of the zipper; 3.Form of the zipper; 4. The form of the zipper.
