Abstract

A boot adapted to the practice of skating and a method of manufacturing such boot, the boot including a shell base equipped with a rigid sole adapted to be attached on the frame of a skate and a heel reinforcement part, and a flexible liner that is positioned inside the shell base including of a padded upper part surrounding the foot and at least one outer pocket portion. The shell base according to the invention has a rigid collar portion that extends the heel reinforcement and the pocket portion at least partially covers the collar portion so as to ensure at least partially the retention of the flexible liner in the shell base. The invention relates to a boot structure encompassing the essential functions of foot retention and controlled flexibility, and whose assembly is made easier.

2. A boot adapted to the practice of skating according to claim 1, wherein the pocket portion only partially covers the shell base so as to leave at least a substantial part of the heel reinforcement free.

3. A boot adapted to the practice of skating according to claim 1, wherein the collar portion is connected to the shell base all in one piece.

4. A boot adapted to the practice of skating according to claim 3, wherein the shell base comprises section reducing means connecting the heel reinforcement to the collar portion so as to allow the collar to bend along at least one preferred direction with respect to the heel reinforcement.

5. A boot adapted to the practice of skating according to claim 4, wherein the section reducing means are positioned in a way that allows a portion of the collar to bend in a substantially longitudinal direction whereas the collar portion opposes a resistance to bending for a lateral retention of the foot.

6. A boot adapted to the practice of skating according to claim 1, wherein the collar portion has a substantially U shaped section along a horizontal plane whose opening is oriented towards the front in the direction of the toe of the shell base.

7. A boot adapted to the practice of skating according to claim 1, wherein the outer pocket portion comprises an opening that is mainly oriented in a direction that helps said collar portion to slide in the pocket portion when the liner is inserted in the shell base.

8. A boot adapted to the practice of skating according to claim 7, wherein the opening of the pocket portion is oriented mainly downwardly in the direction of the sole.

9. A boot adapted to the practice of skating according to claim 7, wherein said pocket portion is mainly formed by a main pliable and flexible portion and a more rigid edge portion extending at least partially along the opening.

10. A boot adapted to the practice of skating according to claim 1, wherein the liner is mounted detachably in the shell base.

11. A boot adapted to the practice of skating according to claim 1, wherein the flexible liner comprises a sole portion connected to a portion of the flexible upper extending from the toe of the foot to the heel and that rises in the direction of the lower part of the leg.

12. A boot adapted to the practice of skating according to claim 1, wherein said shell base comprises a toe reinforcement part and lateral foot retention parts extending beyond the plane of the sole and demarcating a longitudinal opening, together with the sole and the heel reinforcement they form a receiving and retention cavity for a part of the liner.

13. A boot adapted to the practice of skating according to claim 12, wherein the lateral foot retention parts are extended via substantially rigid flaps that border at least a portion of the longitudinal opening, said flaps comprising tightening elements that are used to contract the longitudinal opening and limit the volume of the cavity around a part of said liner.

14. A boot adapted to the practice of skating according to claim 1, wherein said pocket portion extends from the top of the collar portion to a zone located above the sole of the shell base in the heel reinforcement region.

15. A boot adapted to the practice of skating according to claim 1, wherein said pocket portion comprises attachment elements on the shell base.

16. A boot adapted to the practice of skating according to claim 15, wherein the attachment elements on the shell base are located on either side of the shell base.

17. A boot adapted to the practice of skating according to claim 15, wherein the attachment elements are detachable elements, said elements comprising members selected from the group consisting of clips, screws, staples, buckles, and hook and loop fasteners.

18. An in-line skate equipped with a boot according to claim 1.

19. A method for manufacturing a boot adapted for the practice of skating comprising:

providing a flexible liner comprising a padded upper part and at least one flexible pocket portion fixed with respect to said upper part to create an opening between said upper part of said liner and said pocket portion;

manufacturing a rigid shell base separately from said liner, said shell base forming an open cavity and comprising a rigid sole, a reinforcement portion, at least a portion of the collar extending the shell base;

assembling said flexible liner to the shell base by introducing a part of the liner in said cavity and by threading at least a part of the collar portion through the opening between said upper part of said liner and said flexible pocket portion.

20. A method according to claim 19, wherein:

said opening of said flexible pocket portion of said flexible liner is downwardly facing.

21. A boot comprising:

a shell base comprising;

a rigid sole adapted to be attached onto a frame of a skate;

a heel reinforcement portion; and

a rigid collar portion extending upwardly from said heel reinforcement portion;

a flexible liner positioned inside said shell base, said flexible liner comprising a flexible outer envelope, an inner padding within said flexible outer envelope and adapted to extend around a user'"'"'s foot, and at least one flexible outer pocket portion affixed to said flexible outer envelope, an opening being formed between said flexible outer pocket portion and said flexible outer envelope;

said flexible outer pocket portion at least partially covering said rigid collar portion, with said rigid collar portion extending through said opening between said flexible outer pocket portion and said flexible outer envelope, when said liner is received within said shell base.

22. A boot according to claim 21, wherein:

said flexible liner further comprises a sole portion connected to a portion of said flexible outer envelope extending from a toe area to a heel area and rising in an upward direction of a lower part of a leg of a user.
