#W7/iam R. Caine United States Patent O 3,496,656 SPRING LOADED SHOE FIXTURES William R. Caine, 1191 Crestwood Drive SE., Atlanta, Ga. 30316 Filed Nov. 20, 1967, Ser. No. 684,375

Int. Cl. A43b 5/00 U.S. Cl. 36-67 3 Claims ABSTRACT F THE DISCLOSURE A device which is used in plurality and is attached to the soles of shoes having a base member which is attached by its flange to the sole of a s-hoe. Screws are used to secure the base member and its associated flange to the sole of the shoe and an opening within the base extends through the externally threaded extension and carries a coil spring which urges against the head of a rubber tipped pin, the pin extending from an internally threaded member which is threaded onto the extension of the base of the device, the pin when riding against the internally enclosed spring as the pressure iis applied to the pin allows the pin to slide into the device and when pressure is released from pin, the spring urges outwards against the head of the pin to again seat the 'head of the pin and cause a lifting reaction through the shoe.

This invention relates to shoe attachments, and more particularly to a spring-loaded fixture for shoe soles and the like.

It is therefore the main purpose of this invention to provide a spring loaded shoe fixture which will be used in plurality on the soles of shoes and will thus impart a springiness to the Wearers feet.

Another object of this invention is to provide a shoe fixture which will have a flanged base member which will be secured to the sole and will have an externally threaded extension which threads into a flange member carrying a slidable pin.

A -further object of this invention is to provide a shoe fixture which will have a flanged base member which will two elements, in order to accommodate modified pins if desired.

Other objects and advantages of the invention will become apparent from a consideration of the following detailed description taken in connection with the accompanying drawing wherein a satisfactory embodiment of the invention is shown. However, itis to be understood that the invention is not limited to the details disclosed but includes all such Variations and lmodifications as fall Within the spirit of the invention and the scope of the appended claims.

In the drawing:

FIGURE 1 is a side view of the present invention shown in elevation;

FIGURE 2 is a cross-sectional view taken along the lines 2-2 of FIGURE 1;

FIGURE 3 is an enlarged top plan view of FIGURE 1;

FIGURE 4 is a side elevation of the modified spike for use in the present invention;

FIGURE 5 is a cross-sectional side view in elevation showing a mdiiied form of the main embodiments of the present invention;

FIGURE `6 is a top plan View of FIGURE 5; and

FIGURE 7 is a bottom plan View of a shoe with the present invention installed thereto.

According to this invention, a spring loaded shoe fixture 10 is provided with a base member 11 having a flange 12, the base member 11 being provided with a plurality of spaced apart openings 13 while the flange 12 is provided with a plurality of spaced apart openings 14. Openings 13 and 14 of fixture 10 provide means for securing fixture 10 with tap screw fasteners to a shoe. A central bore 15 of base member 11 carries a compression coil spring 16 which extends into extension 17 of a flared member 18. Extension 17 of base member 11 is externally threaded and threads into the internally threaded flared member 18 and thus forms a closed housing. A counter-sunk headed pin 19 has the head portion resting in a countersunk recess 20 within flared member 18 when fixture 10 is not in use and a rubber tip 2.1 is received on the lower end of pin 19. A steel plate 22 is secured within rubber tip 21 and abuts with the lower extremity of pin 19.

Looking now at FIGURE 4 of the drawing, one will see a modified form of spike 23 which may be used in place of pin 19 if so desired.

As will be seen in FIGURE 7 of the drawing the sole 24 of shoe 25 is provided with a plurality of spring loaded shoe fixtures 10 which are spaced properly apart to effect proper usage of fixtures 10.

In use, a plurality of shoe fixtures 10 are secured to sole 24 of shoe 25 by a screw lfastener (not shown) within the openings 12 and 13 and when the users foot comes in contact with the ground or other surface the pin 19 urges upwards against spring 16 and when the foot is raised the spring 16 again urges the head of the pin 19 downwards again into the counter-sunk recess 20. It will fbe understood that the spring 16 urging against the pin 19 at its upper extremity will impart a springiness to the shoe of the wearer.

Looking now at FIGURE 5 of the drawing, one will see a modified version of shoe fixture 26 which is composed of a cup 27 having a flange 28 in which there are a plurality of spaced apart openings 29 for receiving suitable fasteners for attachment to `a shoe. A compression coil spring 30 is carried within the cup 27 and is secured at its upper extremity thereto. The lower extremity of spring 30 is carried within a similar diameter cup 31 in which a pin 32 extends from the opening 33. Pin 32 is provided with a flat head 34 for bearing with and against the lower extremity of spring 30.

This lmodified form of spring loaded shoe fixture 26 operates in a Similar manner as that heretofore described in the main embodiment of the present invention except that when in neutral position a Space separates the edges of the two caps 27 and 31.

It will be noted that shoe fixtures 10 and 26 may be secured to shoe 25 in any manner desired.

What I now claim is:

1. A sport shoe having a ground connecting surface, a plurality of spring loaded shoe fixtures attached to said surface, each fixture comprising a substantially cylindrical base member having an axial bore formed therein open at one end and closed at the other, a flange portion on the base member at the closed end thereof and secured to said surface, an externally threaded extension on the base member at the open end thereof, an internally threaded member threadingly secured to said extension of said base member and for-ming a cap therefor, said internally threaded member having a centrally located circular opening smaller than said bore, a pin having a circular head and cylindrical shank, said head being substantially the size of said bore and slidingly received therein and said 3 4 shank being substantially the size of said circular opening 2,383,267 8/ 1945 Malmqvist 36-67.5 X and extending therethrough, and a compression spring 2,421,072 5/ 1947 Kramer 36-67.5 within said bore between said closed end and said pin 2,408,617 10/ 1946 Ferrar 36-7.8 head. 2,837,840 6/ 1958 Kerpel 36-7.8

2. The pin of claim 1 comprising a sharp pointed end. 5 FOREIGN PATENTS 3. The pin of claim 1 comprising a rounded tip.
