Locking device for a sports shoe

A sports shoe including:

• a shell,
• a cuff hinged relative to the shell, and
• a locking device adapted to immobilize a hinge between the shell and the cuff,
• the locking device including an immobilizing element mobile between an immobilizing position and a release position, and a conjugate element adapted to cooperate with the immobilizing element to immobilize the hinge when the immobilizing element is in the immobilizing position, the immobilizing element being moved away from the conjugate element to release the hinge when the immobilizing element is in the release position,
• wherein the locking device includes a shaft secured to the immobilizing element, a casing including at least one first guide opening, a carriage mobile relative to the casing, the carriage including at least one second guide opening, the shaft cooperating with the at least one first guide opening and with the at least one second guide opening so that a movement of the carriage relative to the casing drives a movement of the immobilizing element,
• wherein the immobilizing element is mobile parallel to a first axis between the immobilizing position and the release position, the at least one first guide opening being oriented parallel to the first axis, the carriage being mobile relative to the casing parallel to a second axis, the at least one second guide opening being oriented parallel to a third axis, the third axis being at a non-zero angle to the first axis, the third axis being at a non-zero angle to the second axis.

A sports shoe including:

• a shell,
• a cuff hinged relative to the shell, and
• a locking device adapted to immobilize a hinge between the shell and the cuff,
• the locking device including:
• an immobilizing element mobile between an immobilizing position and a release position, and
• a blade fixed to the shell by a rotational connection about a rotation axis, the blade being adapted to be moved relative to the immobilizing element when the immobilizing element is in the release position and the cuff pivots relative to the shell, the blade being adapted to cooperate with the immobilizing element to immobilize the hinge when the immobilizing element is in the immobilizing position,
• wherein the immobilizing element includes a first guide surface and the blade includes a second guide surface, the first guide surface cooperating with the second guide surface to guide a movement of the blade relative to the immobilizing element when the immobilizing element is in the release position and the cuff pivots relative to the shell,
• wherein
• the immobilizing element is mobile parallel to a first axis between the immobilizing position and the release position,
• the blade is moved relative to the immobilizing element parallel to a second axis when the cuff pivots relative to the shell, the second axis being perpendicular to the first axis, and
• the first guide surface and the second guide surface are oriented in a direction transverse to the first axis and to the second axis, so as to guide the movement of the blade along the second axis when the immobilizing element is in the release position and the cuff pivots relative to the shell,
• wherein the immobilizing element includes a lug, and the blade includes a first opening having a shape complementary to a shape of the lug, the lug cooperating with the first opening when the immobilizing element is in the immobilizing position, and
• wherein the locking device includes a casing provided with a wall extending against the blade, the blade being intended to be moved relative to the wall when the cuff pivots relative to the shell, the wall including a second opening, the lug being positioned inside the second opening when the immobilizing element is in the immobilizing position.
