Description

Fi led Aug. 21, 1947 IIIIIIIJIYI-I Inventor Patented Apr. 12, 1 949 UNITED STATES PATENT OFFICE ANTISLIP DEVICE FOR SHOES Alfred Frank Qulla, Milwaukee, Wis. Application August 21, 1941?, SerialNo; $39,980 2 Claims. (disc-s4) This invention relates to new and useful improvements and structural refinements in antislip devices for shoes, and the principal object of the invention is to provide a device of the character herein described, such as may be conveniently and effectively employed in association with shoes, boots, or the like, for preventing the wearer from slipping or skidding on ice, snow, or under similar adverse weather conditions.
A further object of the invention is to provide an anti-slip device of the nature described, which may be quickly and easily applied to the shoe, and which, if desired, may be removed therefrom with equal expediency.
Another object of the invention is to provide an anti-slip device which is simple in construction, which will not easily become damaged, which will readily lend itself to economical manufacture, and which is otherwise well adapted for the purpose for which it is intended.
With the above more important objects in view and such other objects as may become apparent as this specification proceeds, the invention consists essentially of the construction and arrangement of parts as shown in the accompanying drawings in which:
Figure 1 is an underside plan View showing the invention in situ on a shoe,
Figure 2 is a cross sectional view, taken substantially in the plane of the line 22 in Figure 1,
Figure 3 is a side elevation of the subject shown in Figure 1,
Figure 4 is an exploded perspective view of the invention per se,
Figure 5 is a cross sectional view, taken substantially in the plane of the line 5-5 in Figure 2, and
Figure 6 is a perspective view of a screw-threaded shaft used in the invention.
Like characters of reference are employed to designate like parts in the specification and throughout the several views.
Referring now to the accompanying drawings in detail, the invention consists of an anti-slip device for shoes designated generally by the reference character It), the same embodying in its construction a channel ll having a substantially U-shaped cross sectional configuration, one end of this channel being closed by means of an end plate I2, while its remaining end is open, as indicated at is.
It will be noted that the inner surfaces of the side members 14 of the channel I I are formed with a pair of longitudinally extending, mutually opposed guides l4, these being adapted to slidably engage coacting guides l5 formed on the longitudinal edges of a pair of elongated plates 16.
The entire device is adapted for positioning transversely adjacent the under surface of the sole ll of a shoe l8, preferably at the shank portion of the shoe, as will be clearly apparent. Accordingly, one end portion of each of the plates i6 is arcuated so as to provide what may be referred to as a keeper jaw l9, these two jaws being adapted to engage the side edges of the sole l l, as is best shown in Figures 1, 2 and 3.
Means are provided for urging the jaws i9 in engagement with the side edges of the sole, said means consisting of an actuating shaft 20, substantially one-half of which is formed with a right-handed screw-thread portion 2|, while its remaining half is provided with a left-handed screw-thread portion 22. This shaft is longitudinally disposed in the channel I l, and a screwthreaded block 23 is rigidly secured to each of the plates 16, matters being so arranged that each of the blocks operatively engages one screwthreaded portion of the shaft 20 as will be clearly understood. The end portion of the shaft 28 which is disposed in the open end [3 of the channel II is provided with a square adapter 24, this being intended to receive a removable key 25 which is employed for rotating the shaft 20, whereby the jaws iii are simultaneously brought together or separated.
Finally, it should be explained that the under surface of the channel II. is provided with a plurality of suitable traction increasing elements, such as for example, pads of cork or suitable material, or as shown in the accompanying drawings, with a series ofpointed spikes or prongs 26 which are secured to the channel.
Needless to say, when it is desired to install the device in situ on the shoe, the jaws H) are drawn together by rotating the shaft 28 by means of the key 25, until the jaws firmly and securely grip the side edges of the sole [1, as shown. When it is desired to remove the device from the shoe, the shaft 20 is rotated in the relatively opposite direction, so that the jaws iii are disengaged from the shoe sole.
It is believed that the advantages and use of the invention will be clearly apparent from the foregoing disclosure, and accordingly, further description thereof at this point is deemed unnecessary.
While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combifiguration of said channel and thereby constituting guards against entry of foreign matter into said channel, sole engaging jaws provided on said blocks, a screw threaded shaft rotatable in said channel and operatively engaging said blocks,
'4 and means insertable in the open end of said channel and operatively engageable with said shaft.
2. The device as defined in claim 1 wherein the opposing side walls of said channel are formed in their inner surfaces with longitudinally extending grooves, said jaws including pairs of guides slidably engaging said grooves.
ALFRED FRANK QUELLA.
