Sliding lock, in particular for footwear

Patented in the German Empire on November 24, 1931

The invention is a sliding lock for footwear, tents and the like. which consists of bodies sliding in guides and whose guides consist of individual ones Limbs are composed, which carry noses lying in the locking direction. The invention initially differs from the known closures of this type in that the connecting links with two

xo part, angular, superimposed, separated by the sliding space for the body fitting pin and corresponding fitting openings are provided for the pins of the next link. This prevents the closure from flexing when compressive loads occur any direction prevented. Furthermore, the individual links are bevelled provided in order to achieve an unrestrained transition from one link to the other.

Finally, the guides accommodating the sliding bodies consist of individual parts that widen and narrow in cross section between two boundaries and are in turn connected to one another with peg-shaped projections Way prevented.
The subject matter of the invention is illustrated in some exemplary embodiments in the drawing. Show it:

Fig. Ι the lock in plan and elevation in the open state,

Fig. 2 the closure in the tied up state in plan and elevation,

Fig. 3 shows a lock in elevation and side elevation,

Fig. 4 a closure with elastic guides in plan and elevation,

Fig. 5 is a diagrammatic representation of a guide member,

Fig. 6 the elastic guidance of a closure in plan and elevation,

Fig. 7 is a view and a longitudinal section through a trumpet-tube-like part,

Fig. 8 a section along line AB in Fig. 7.

The rigid guides 1 of the closure are made of any building material and connected to the tracks 4 in a known manner. A closure means 2 consists of an elastic one Building material, a cord, chain, etc., or from rigid pieces that are hinged together are connected. The bodies 3 are mostly in uniform with the closure means 2 Distances firmly connected. They are alternately stored in the guides 1. At the At the beginning and at the end of the closure means 2 there are several bodies 3 at small intervals which connect the locking means 2 to the guide 1 by a lock 5 attached to each guide opening. When the lock is closed, the bodies 3 protruding from the guide 1 become prevented from entering. By pulling on the end 6 of the closure means 2 is a

Achieved elongation, the body 3 slide in the guides ι. By mutual Storage, the two guides are tied together, as shown in Fig. 2. The lock consists of a U-shaped bent spring wire 5, which is inserted into the guide 1 as an elastic closure.

The end 8 of the lock is seated in holes, while the end 9 is received in a slot 10 finds. As soon as a body 3 emerges from the guide 1 when the closure is closed, he pushes the end 9 of the spring 5 out of the slot 10 and pushes it upwards, so that the Body leave the guide 1 canoe. After the body 3 has passed by, it snaps End 9 of the spring 5 back into the slot 10 and is returned by the Body 3 held when the lock is stressed. The body 3 can no longer push the end 9 of the spring 5 upwards, since the edge 11 of the slot 10 this movement prevented. When the lock is opened, the lock 5 and the locking means are released 2 pulled back by hand or by an attached spring or elastic cord 7.

A closure with elastic guides 12

is illustrated in fig. It is made up of individual members 13 of any building material, which are connected to ^{one another by pins 14 ° and 14 *, as well as corresponding fitting openings 2i a} and 21 * (Fig. 5), so that the individual members can flex when subjected to pressure by the Body 3 is prevented. A cavity is used to accommodate the bodies 3.

It is fastened to the tracks 4 in a known manner. The contact surfaces 22 of the links 13 are bevelled, as shown in FIG. 5, so that the links 13 nestle against one another when the guides 12 are bent i ^ ^a , 14 * and the pass openings 2i ^a , 2X ^b .

Figs. 6 to 8 illustrate elastic guides 15, which are made of individual trumpet-shaped tubes bent parts 16 are composed of any building material and through Pin 17 are kept in connection with one another.

The body 3 slide on the edge 18 and can move through the trumpet-like design Move more easily through the individual guide members 19, 20 when the guides are bent and don't get stuck.

Claims (4)

Patent claims: 1. Sliding closure, in particular for footwear, which consists of bodies sliding in guides and whose guides are composed of individual members that carry noses in the closure direction, characterized in that the connecting members (13) with two-part, angular, superimposed, through the Sliding space for the body separate fitting pins (i4 ^a , 14 *) and corresponding fitting openings (2i ^a , 2i ⁶ ) for the fitting pins of the next link are provided. 2. Sliding closure with a cavity according to claim 1, characterized in that the cavity receiving the sliding body (3) between the fitting pin (14 ¹ ^ 14 *) and the fitting openings (2i ^fl , 21 *) and the individual edges with bevels ( 22) are provided so that the links (13) nestle against one another when the guides (12) are bent. 3. Sliding closure with a cavity according to claim 1, characterized in that that the sliding body (3) receiving guides (16) from individual, in cross section continually expanding and narrowing parts between two boundaries (19, 20) assemble, which are connected to one another with peg-shaped projections (17) are. 4. sliding closure according to claim 1, characterized in that one of a Wire bracket (5) existing locking with go one leg (8) is fixed and with the other leg (9) in a slot (10) whose edges (11) den hold said leg and an entry of the sliding body (3) into the guides impede. 1 sheet of drawings
