United States Patent DETACHABLE ANTISLIP DEVICE Frank C. Miller, Phoenix, Ariz.

Application March 3, 1958, Serial No. 718,727

4 Claims. (Cl. 36-7.7)

The present invention relates to a device which may be applied to the soles of shoes to provide the wearer with means to obtain a secure foothold when walking or climbing.

A device of this type has numerous applications in various fields under conditions where it is desirable or necessary to obtain a greater than normal frictional contact between the sole of the shoe and the terrain, as for example when employed for use in various sports which require a firm foothold, as in golf, baseball or in hillclimbing.

The present device is so constructed and arranged as to make practical and eifective an antislipping appliance which may be applied to or removed from the shoe by a simple operation in the absence of any mechanical adjustments. By reason of the simplicity of its application and removal, the present device may serve the needs of not only the actual participants in a sport such as golf, but finds use by others who travel the course as spectators.

Various forms of calks or cleats for shoes have heretofore been proposed, all of which required certain mechanical adjustments after application to the shoe and readjustment prior to removal. Devices of this type have their use but require an appreciable amount of time and effort for application and removal and are cumbersome and unwieldy, especially in cases where a temporary or relatively limited use of the device is required.

The present invention provides a calk or cleat device which may be attached by the simple operation of drawing the cleat device over the sole of the shoe, whereupon the adjustment to secure the device to the sole of the shoe is automatic and the device is locked in position for use. The removal is equally as simple since a release of one portion of the device results in a complete release. The entire operation is on the order of the insertion and removal of the foot into and out from an ordinary low shoe or oxford.

By reason of the construction and cooperative arrangement of the several parts of which the present device is composed, it may be quickly and conveniently secured or removed when applied to shoe soles of varying sizes.

The advantages and objects of the invention will be more clearly understood by reference to the following description together with the accompanying drawing in which:

Fig. 1 is a side elevational view showing the device applied to the sole of a shoe;

Fig. 2 is a plan view showing the surface of the device to receive the sole of the shoe; and

Fig. 3 is a view taken in cross section on line IlI-III in Fig. 2.

As disclosed in the drawing, one practical embodiment of the invention includes two arcuate metal strips termed plate-members and 11 hingedly connected at adjacent ends 13 and 14 by pivot pin 15, which pin also secures a clip-member or clamp 16 in position to engage the forward edge of a sole 12 of shoe 12. Each plate-member the may be provided with a plurality of spaced apart cleats or spikes 20. These spikes may be in the form of separate members riveted or otherwise secured to what may be termed the under sides of the plate-members, or they may be punched or formed from the sheet material of the plate-members.

Intermediate the ends of the plate-members and extending outwardly therefrom are clip-members 17 adjustably attached to the plate-members. These lateral clipmembers or clamps 17 are secured by and are free to swivel about rivets 18 to permit free adjustment to accommodate variations in the contour of the edge of a shoe sole to assure firm contact with shoe soles of various sizes.

Ends 19 and 21 of the plate-members are connected and retained in normal spaced relation by one portion 22 of what may be termed a retainer 23. This retainer-member 23 is formed from a sheet of elastic material, as for example, rubber of a selected thickness, and'includes a loop portion 24. which extends beyond the ends 19 and 21 of the plate-members. The said portion 22 of the retainermember 23 is secured to ends 19 and 21 of the platemembers by means of rivet pins 24 and 25 which also attach clip- members 26 and 27 to ends 19 and 21 respectively of plate-members 19 and 11. The clip- members 26 and 27 are so arranged as to swivel about the pins 24 and 25 to permit adjustment as in the case of clip-members 17.

The portion 22, of retainer member 23, serves as a tension-member which, when contracted, holds the ends 19 and 21 of the plate-members in fixed normal spaced relation but permits limited separation of the platemembers about their hinged connection when force is applied.

When the present antislip device is applied to a shoe, the ends 19 and 21 of the plate-members are separated in opposition to the elastic tension-member 22. The platemembers may then be placed into contact with the sole of the shoe and the clip-members adjusted to engage the edge of the sole. Since the lateral clip-members are movable about their pivots, the device is readily fitted to the shoe sole with the clip-members engaging the sole edge as the plate-members are permitted to move together, at which time the forward clip-member 16 is engaged with the front end of the sole. When so positioned, the loop portion 24. of retainer-member 23 is expanded and then permitted to contract about the heel of the shoe, thereby exerting tensional stress to maintain the device in firm operative relation to the shoe.

It will be evident that inasmuch as the loop 24 when contracted or normal is relatively small, the enlargement of the loop, when expanded about the heel, exerts a pull on the tension-member or portion 22. This portion is then distorted and exerts a pull between the ends 19 and 21 of plate-members 10 and 11. The plate-members being pivoted at their ends serve to hold the clip-members in fixed relation to the sole of the shoe, and since the lateral clipmembers are movable about their pivots, they are automatically adjusted to provide firm contact with the edge of the sole.

When the device is to be removed, the loop 23 is expanded and released from the heel. This results in the automatic removal of the added tension applied to the ends of the plate-members, due to the expansion of portion 22, whereby the clip-members may be readily disengaged with the sole edge and the device put in condition to be easily removed.

Although a preferred embodiment of the invention is shown and described herein, it is to be understood that modifications may be made therein without departing from the spirit and scope of the invention as set forth in the appended claims.

What is claimed is:

1. A detachable antislip device to be applied to the sole of a shoe, comprising a pair of arcuate plate-members, means for hingedly connecting said plate-members at adjacent ends" thereof, a tension-member of elastic sheet material connected to and normally serving to hold oppositeends of said plate-members in spaced relation, clipmembers disposed along the edges of said plate-members and pivotally attached thereto for adjustable contact with the edge of a shoe sole when said plate-members are separated in opposition to tension exerted by the tensionmember, said tension member when released serving to hold said clip-members in adjusted contacting relation with the edge of said sole.

2. A detachable antislip device to be applied to the sole of a shoe, comprising a pair of plate-members pivotally connected at adjacent ends thereof, a plurality of clipmembers mounted on said plate-members, a retainer member consisting of elastic sheet material, including a tension-portion connecting opposite ends of said platemembers and a loop portion for disposition about the heel of said shoe whereby said retainer member will secure the device on the shoe and lock the clip-members in firm contact with the edge of said sole.

3. A detachable antislip device to be applied to the sole of a shoe, comprising a pair of plate-members hingedly connected at adjacent ends thereof, a plurality of clipmembers pivotally' mounted on said plate-members; a tension-member formed from elastic sheet material connecting opposite ends of said plate-members, a loop portion of elastic sheet material integral with said tensionmember for disposition about the heel of said shoe to hold the device in place and to exert stress to contact said tension-member between the ends of said plate-members to hold said clip-members in firm, adjusted contact with the edge of the sole of the shoe.

4. A detachable antislip device to be applied to the sole of a shoe, comprising a pair of arcuate plate-members, clip-members adjustably mounted on said plate-members, means for hingedly connecting adjacent ends of said platemembers, an elastic sheet-member, one portion of said sheet-member serving as a tension-member between opposite ends of said plate-members,-a loop-member integral with said tension-member for disposition about the heel of said shoe to hold said plate-members in firm contact with said sole and to stress said tension-member to retain said clip-members in firm contact with the edge of said sole.
