Title:
SNOW AND ICE ANTI-SKID DEVICES FOR SHOES
United States Patent 3834045
Abstract:
A novel cleat securable to the underside of a shoe in order that a person wearing the same can walk on slippery surfaces without slipping; the cleat in one form of the invention consisting of a pair of metal bars connected pivotally together at their centers, one end of the bars being bent to clamp around a shoe sole, and the other end being connected to an elastic band extending around the shoe heel, the underside of the bars having projections for frictionally engaging a walking surface; and the invention in another design consisting of a rotatable roller having a row of projections that are rotatable between a utility and retracted position.

1. In a snow and ice anti-skid device for shoes, the combination of a means for securement of said device to an underside of a shoe sole, and means for frictionally engaging an icy or snowy surface, said securement means including a pair of clamps for grasping around opposite side edges of said shoe sole, said engaging means comprising a plurality of pointed projections, said projections forming a row along a rotatable roller, said projections being on an underside of a pair of bars attached scissors-like together and normally urged closed by an elastic band.

Description:
This invention relates generally to shoe cleats.
A principal object of the present invention is to provide an anti-skid device mountable under shoes so that a person can walk on snow and ice without danger of slipping and falling down.
Another object is to provide a snow and ice anti-skid device for shoes which can be quickly installed on the shoes when wanted, and which is then readily removable when no longer needed.
Yet another object is to provide a snow and ice anti-skid device for shoes which is self-adjustable to fit all sizes of footwear.
Other objects are to provide a snow and ice anti-skid device for shoes which is simple in design, inexpensive to manufacture, rugged in construction, easy to use, and efficient in operation.
These and other objects will be readily evident upon a study of the following specification and the accompanying drawing, wherein:
FIG. 1 is a top view of one design of the invention.
FIG. 2 is a side view thereof.
FIG. 2a is an end view thereof.
FIG. 3 is a bottom view of a modified design of the invention shown secured to an underside of a shoe.
Referring now to the drawing in detail, and more particularly to FIGS. 1 and 2 at this time, the reference numberal 10 represents a snow and ice anti-skid device according to the present invention, wherein there is a roller-shaped member 11 having a single row of pointed projections 12 on its underside. A shaft 13 is secured fixedly to one end thereof, and a threaded shaft 14 is screw-thread into an opposite end thereof.
The shaft 13 extends through a bracket 15, while shaft 14 extends through a bracket 16. The bracket 15 is affixed to the underside of a top plate 17 having a clamp 18 formed at one end. The bracket 16 is affixed to the underside of a top plate 19 having a clamp 20 formed at one end. The top plate 17 adjustably overlaps the top plate 19 and is selectively securable thereto so to adjust to shoe width, by means of adjustment screws 21 passed through slots 22 of top plate 17 and into threaded openings of top plate 19. The clamps serve to grip around the edges of a shoe sole. The threaded shaft 14 has a knurled head 23 for easy turning, the shaft extending through a wafer washer 24. A locking device 25 is affixed to shaft 13 and is associated with a spring steel spring leaf 26, so to maintain the locking device locked in either opening 27 or 28. When the locking device is in the position as it is shown in FIG. 22, the projections 12 extend downward for use; when the locking device engages opening 28, the roller member is rotated so the projections extend generally horizontally retracted by pointing toward a heel. To adjust the device to fit a shoe, the screws 21 are first loosened before turning the knurled screw head 23.
In FIG. 3, another design 29 of the invention consists of metal bars 30 pivotably attached on a common rivet 31. An upward clamp 32 is on one end of each bar, and the other ends are attached to opposite ends of an elastic band 33 placeable around a shoe heel 34. The elastic band maintains forces of the clamps 32 grip around opposite side edges of shoe sole 35. Downward projections 36 on the bars serve to grip a snow or ice surface.
