Abstract

A convertible sports shoe includes a shoe body having a sole, and a plurality of cooperating projections and recesses provided on a sports device and the sole for detachably connecting the sports device to the shoe body. A plurality of different sports devices are provided, and a selected one of these devices is interchangeably mounted on the sole.

Claims

1. A shoe sport arrangement, comprising a shoe body having a sole integrally connected to said show body;

a plurality of different sports devices, each adapted for use in a different sport, and means for interchangeable mounting a selected one of said devices on said sole, including cooperating projections and recesses provided on each of said devices and said sole, respectively, for detachably connecting a selected one of said sport devices to said shoe body, and elongated bores in communication with said recesses and each extending transversely of said recesses, said projections being partly extendable into said bores so as to permit dislodging of the sports devices by urging the projections lengthwise of the respective recesses by applying pressure on the recesses through the bores and in direction lengthwise of the sole.

2. The arrangement as defined in claim 1, wherein each sports device has at least two of said projections;

and wherein said sole has at least two of said recesses for respectively receiving said two projections.

3. The arrangement as defined in claim 2, wherein said sole has a heel portion and a toe portion, each of said portions bounding a respective one of said recesses and having an opening through which a respective one of said projections is inserted.

4. The arrangement as defined in claim 3, wherein each recess is elongated and extends along an axis;

and wherein said two recesses have colinear axes.

5. The arrangement as defined in claim 3, wherein each recess is elongated and extends along an axis;

and wherein said two recesses have axes parallel and offset relative to each other.

6. The arrangement as defined in claim 1, wherein each recess is tapered along a predetermined direction;

and wherein each projection is tapered along said predetermined direction.

7. The arrangement as defined in claim 1, wherein said mounting means further includes means for fixing said selected device to said shoe body.

8. The arrangement as defined in claim 7, wherein said fixing means includes a passage for fittingly receiving a locking pin, said passage extending through said sole and communicating with one of said recesses.

9. The arrangement as defined in claim 7, wherein said selected device has an extension, and wherein said fixing means includes a passage for fittingly receiving a locking pin, said passage extending through said extension.

10. The arrangement as defined in claim 7, wherein said fixing means includes a resilient clip having a main portion and a pair of flexible arms at respective opposite ends of said main portion;

and wherein said clip is mounted intermediate a selected one of said sports devices and said sole for urging said selected device into a fixed position relative to said sole.

11. The arrangement as defined in claim 1, wherein said cooperating projections and recesses are elongated along an axis;

and wherein said mounting means further includes means for preventing turning movement of said sports device relative to said shoe body about said axis, said preventing means including support portions on a selected one of said devices and engaging said sole.

12. The arrangement as defined in claim 11, wherein said support portions engage said sole at two locations on opposite sides of said axis.

13. The arrangement as defined in claim 1, wherein one of said devices is an ice blade, another of said devices is a roller body, and still another of said devices is a walking stilt pole.

16. The arrangement as defined in claim 7;

and further comprising means for removing a selected one of said devices from said shoe body including a removal tool having a handle portion and a pair of arms at respective opposite ends of said handle portion, each arm being receivable in a respective clearance.

17. The arrangement as defined in claim 8, wherein each arm extends and is tapered in direction away from said handle portion.

14. An arrangement for converting a shoe for different sports, comprising a shoe having a sole;

a plurality of different sports devices each adapted for use in a different sport; and

means for interchangeably mounting a selected one of said devices on said sole, including cooperating projections tapered in a predetermined direction and recesses also tapered in said predetermined direction provided on each of said devices and said sole for detachably connecting a selected one of said devices to said shoe body.

15. The arrangement as defined in claim 14, wherein each recess is elongated;

and wherein said mounting means further includes bores in communication with said recesses, each of said bores extending transversely of said recesses and having spaced ends; and

wherein each projection has a free end which extends past one of said ends of said bore upon insertion of said projection into a respective recess and which is spaced at a clearance from the other of said ends of the respective bore.

18. A shoe as defined in claim 14, wherein said sole has a heel portion and a toe portion, and wherein one of said portions bounds a pair of recesses, and wherein another of said portions bounds another recess.
