Skate boot having a tendon guard with a recess
View Patent ↗A skate boot comprising an outer shell with a heel portion for receiving the heel of the foot; an ankle portion for receiving the ankle, the ankle portion comprising a rear portion for facing at least partially the lower part of the Achilles tendon; and medial and lateral side portions for facing the medial and lateral sides of the foot respectively. The skate boot also comprises a tendon guard extending upwardly from the ankle portion of the outer shell for facing at least partially the upper part of the Achilles tendon, the tendon guard comprising a recess for receiving an insert. The tendon guard has a first flexion mode when no insert is received in the recess and a second flexion mode when the insert is received in the recess. The second flexion mode is different from the first flexion mode.

3. The skate boot of claim 1 , wherein the recess is capable of retaining the insert via a press-fit.
4. The skate boot of claim 1 , wherein the recess is capable of retaining the insert via a snap-fit.
5. The skate boot of claim 1 , wherein the tendon guard includes at least one protrusion or groove adapted to cooperate with a corresponding groove or protrusion on the insert.
6. The skate boot of claim 1 , wherein the tendon guard is made by injection molding.
7. The skate boot of claim 1 , wherein, the flexing portion being capable of flexing rearwardly from an initial position when pressure is applied on it and returning to the initial position when pressure is no longer applied on it.
8. The skate boot of claim 7 , wherein the bottom portion of the tendon guard has a U-shaped groove and wherein the U-shaped groove at least partially receives a top edge of the rear portion of the ankle portion.
9. The skate boot of claim 1 , wherein the tendon guard is removably attachable to the ankle portion of the outer shell.
10. The skate boot of claim 9 , wherein the tendon guard includes a slit extending across the recess, thereby permitting the tendon guard to be bent to facilitate placement of the insert into the recess.
11. The skate boot of claim 10 , wherein the tendon guard generally lies within a plane and wherein the slit generally separates the tendon guard into a first portion and a second portion, the first portion being capable of out-of-plane bending and in-plane bending with reference to the second portion.
12. A skate boot for enclosing a human foot when in use, the foot having a heel, an ankle with a medial malleolus and a lateral malleolus, an Achilles tendon having an upper part and a lower part that projects away from the upper part, the lower part merging with the heel, a plantar surface, medial and lateral sides and toes, the skate boot comprising:
(a) an outer shell comprising a heel portion for receiving the heel of the foot; an ankle portion for receiving the ankle, the ankle portion comprising a rear portion for facing at least partially the lower part of the Achilles tendon; and medial and lateral side portions for facing the medial and lateral sides of the foot respectively;
(b) a tendon guard extending upwardly from the ankle portion of the outer shell for facing at least partially the upper part of the Achilles tendon, the tendon guard allowing backwards flexion of the ankle when the foot moves towards full extension, the tendon guard comprising a recess configured to retain an insert, wherein, in use, a first insert selected among a plurality of inserts is mounted in the recess such that the tendon guard has a first flexion mode; and wherein the tendon guard comprises a bottom portion affixed to the rear portion of the ankle portion, the recess being located at least in part in a lower region of the flexion portion, and a flexing portion projecting upwardly from the bottom portion for facing at least partially the upper part of the Achilles tendon.
13. In combination:
a skate boot for enclosing a human foot when in use, the foot having a heel, an ankle with a medial malleolus and a lateral malleolus, an Achilles tendon having an upper part and a lower part that projects away from the upper part, the lower part merging with the heel, a plantar surface, medial and lateral sides and toes, the skate boot comprising:
an outer shell comprising a heel portion for receiving the heel of the foot; an ankle portion for receiving the ankle, the ankle portion comprising a rear portion for facing at least partially the lower part of the Achilles tendon; and medial and lateral side portions for facing the medial and lateral sides of the foot respectively; and
a tendon guard extending upwardly from the ankle portion of the outer shell for facing at least partially the upper part of the Achilles tendon, the tendon guard allowing backwards flexion of the ankle when the foot moves towards full extension, the tendon guard comprising a recess; and
an insert for insertion into the recess of the tendon guard, wherein the tendon guard has a first flexion mode when the insert is received in the recess and a second flexion mode when the insert is not received in the recess, the second flexion mode being different from the first flexion mode.
14. The combination of claim 13 , wherein the tendon guard extends along a longitudinal axis and wherein the recess extends transversally to the longitudinal axis of the tendon guard.
15. The combination of claim 13 , wherein the second flexion mode is dependent on specifications of the insert, the specifications comprising dimensions, shapes, densities, thicknesses or hardness values.
