Patented Nov. 7, 1933 SHOE FASTENER Josef Stande, Gross-Schonau, Czechoslovakia, and Fritz August Petzold, Herzogenrath, near Aachen, Germany Application June 30, 1932, Serial No. 620,146, and in Czechoslovakia `une 13, 1931 2 Claims.

This invention relates to shoe-fasteners, more especially to that kind of shoe-fasteners, in which separate elastic fastening elements are passed through each pair of opposite eyelets. Fasteners of this kind were proposed in which the fastening 3 elements were formed by the usual eyelets in connection with hemispheroidal parts which were pressed into the eyelets from without (thus forming so-called snappers or press-buttons) and were lo connected by elastic strips or helical springs. Such fasteners, however, presented the drawback that they did not sustain for long the different tensions which are exerted on the shoe owing to the movement of the foot when stepping or bend- 1 ing. Other fasteners have been described in which 5 an elastic strip carries a cross-head at one end and a nger at the other. The nger is passed through an eyelet from the inside and then through the opposite eyelet from the outside.

The application of this fastener is very troublesome, especially the insertion of the ringer from the outside. Moreover the eyelets must be given a considerably greater diameter than they tubular parts of the fastener to be placed in the eyelets, whereby an undesired slipping-out of the fastening elements is facilitated.

All these drawbacks are avoided by the shoefastener according to the present invention. The invention is illustrated in the annexed drawing. of which Fig. l is a fractional view of a shoe showing a series of the improved fasteners in position.

Fig. 2 is partly a side elevation of a shoe fastener element, partly a cross-section of the upper of the shoe, taken on a line connecting the centers of two opposite eyelets.

Figs. 3 and 4 are details of the fastening elements. The same reference letters are used for corresponding parts in each of the ilgures.

a, a are elements adapted to connect two loops or eyes b, b which preferably are made of an elastic cord or string band. The ends of these elastic loops are firmly clamped into suitable heads. For this purpose, we prefer to use rivet- 45 like heads d, d consisting of small tubes and very at flanges which do not molest the wearer in any way.

The elastic loops, shown separately in Fig. 3, are passed through two opposite eyelets c, c from the inside and then connected by a clamp a. The latter may consist of a metallic wire the ends of which are bent to form hooks. One of these hooks may be, after insertion of an elastic loop b, nearly closed, so that generally both parts remain connected or can be separated only with difiiculty. Of course, the clamp a is then passed through an eyelet from the inside of the shoe, so that the attached elastic loop follows after. The insertion of the other end of the clamp into the second elastic loop may be facilitated by a small shoe-buttoner.

A shoe-fastener according to the present invention absolutely secures a durable connection of the two halves of the upper, the connection is easily and quickly made, and the at anges of the heads which touch the foot do not trouble the wearer in the slightest degree.

We claim:-

l. A shoe-fastener consisting of a plurality of elements, each element comprising two elastic loops adapted to be passed through the complementary eyelets located opposite each other on opposite sides of the slit of a shoe, heads which are secured to each end of the said loops and which have a diameter greater than the inner diameter of the eyelets, and a plurality of hooked clamps each of which is adapted to engage one of the said pairs of elastic loops.

2. A shoe-fastener element comprising two elastic loops adapted to be passed through the complementary eyelets located opposite each other on opposite sides of the slit of a shoe, rivetlike heads consisting of flat flanges and small tubes into which the ends of the said loops are squeezed, the flanges having a diameter greater than the inner diameter of the eyelets, and a hooked clamp adapted to engage the said two elastic loops.
