Abstract: The present invention relates to a size-adjusting fastening mechanism for stakes comprising fixed locking grooves and a movable locking convex block, whereby when one of the grooves engages with the convex block, tooth position is loosened and toecap is telescopic upon pulling. When the groove and the convex block are rotated to deflect so as not to engage with each other, tooth position is pressed to lock so as to be irremovable. Such a structure requires that the pull handle be pulled horizontally forwards and backwards. Being secured with rivet punching, the claimed device possesses good stability, is simple in structure, low in cost and easy for operation.

Abstract: An ice skate strip-blade holder that provides a means to remove, replace, tension, and maintain tension in a strip-blade fastened and tensioned on the holder. In a preferred embodiment, the strip-blade holder assembly includes a front segment fixed to the skate plastic superstructure; a latched, pivoting rear segment arranged to apply and maintain tension in the strip-blade. In a preferred embodiment, the pivot and latch are positioned such that the pivot carries the majority of the tensile load maintained in the strip-blade and the latch carries a minor component of this tensile load. This arrangement provides for easy latch release. The latch provides release of the rear segment for subsequent pivoting and unhooking of the strip-blade for replacement.

Abstract: Cross-country or telemark binding (10) which is mounted on the top face of a ski, especially on a mounting plate (12) mounted thereon, so as to be longitudinally displaceable (arrow 13) and which is lockable in a plurality of sliding positions by means of a locking device (14). The locking device is subdivided into a first locking unit (23), which is active only in the forward direction, and a second locking unit (24), which is active only in the rearward direction, so that on unlocking of that locking unit (23) which is active only in the forward direction the binding is displaceable only in the forward direction (arrow 25) and on unlocking of that locking unit (24) which is active only in the rearward direction the binding is displaceable only in the rearward direction (arrow 26).

Abstract: The present invention teaches an apparatus and method for removably securing an article of footwear suitable for walking, running, or bicycling to a wheeled skate. Further, the present invention also teaches a brake device for use with a wheeled skate. In addition, the present invention teaches a wheeled skate including a suspension system that can be propelled with the use of linear or side stroke skating techniques. Moreover, the present invention teaches a quad wheeled skate having advantageous structure and function for recreational skating and aerobic exercise.

Abstract: For a glide sport article, especially an ice skate with a shoe body that is located on a chassis and that includes a cap-like shoe tip forming the toe area of the shoe body, a shoe body section forming the heel area and an ankle support, lacing on the shoe body section and a tongue located beneath the lacing, the shoe tip can be adjusted in a shoe body direction relative to the shoe body section on the chassis.

Abstract: An adjustable skate includes a boot, a liner, and an adjusting device. The boot includes a toe cap, a heel portion, and a sole. The liner is mounted in the boot and includes a bottom plate and a toe box. A chamber is defined between the toe box and the heel portion of the boot for receiving a foot of a wearer. The adjusting device is mounted below the sole and includes a screw rod and a screw rod jacket. The screw rod jacket includes a longitudinal screw hole threadedly engaged with a threaded portion of the screw rod. The screw rod jacket is fixed below the liner to move therewith. When the screw rod is turned, the screw rod jacket moves in a longitudinal direction of the screw rod and the liner moves in a lengthwise direction of the chamber.

Abstract: A size-adjustable in-line skate having a base carrying a plurality of wheels thereon. An upper is secured to a top surface of the base and defines a heel portion, a toe portion, and diametrically opposed side wall portions. The upper is supported by a support structure that includes a heel cup and a toe cup. The toe cup is secured to the toe portion of the upper and slideably coupled to the base so that the toe cup can slide longitudinally with respect to the base. An actuator is coupled to the toe cup and travels therewith. When the actuator is translated, engagement members on the actuator disengage with detents on the base to allow the toe cup to freely slide between longitudinal positions to adjust the shoe size of the skate.

Abstract: An adjustable frame assembly for skates to allow for attachment of the frame in a number of positions along the length of the boot portion of the skate. The assembly comprises a skate foot bed containing two recessed portions each containing an opening flanked by ribs corresponding to ribs on a T-nut allowing the T-nut to rest in a variety of positions in the recessed portion. The T-nut further comprises a threaded opening for coupling to a fastener which attaches the frame to the base of the boot portion of the skate.

Abstract: An in-line skate includes a sole plate having wheels rotatably connected to the underside of the sole plate and two elongated first slots are longitudinally defined through the sole plate. A rear portion of vamp is connected to a connection wall on the sole plate. A toe part has two elongated second slots longitudinally defined therethrough and a front portion of vamp is connected to the toe part. The toe part is connected to a top of a front end of the sole plate. Two adjusting members extend through the second slots in the top part and the first slots in the sole plate and are cooperated with two quick-release levers located at the underside of the sole plate such that the toe part can be moved relative to the sole plate by operation of the adjusting members.

Abstract: An adjustable in-line skate has a rigid frame, a plurality of wheels rotatably secured to the frame in a line, a sole plate secured to the frame having a heel portion and a toe portion, and a boot mounted on the sole plate. The boot has a toe shell and a separate heel shell. The heel and toe shells are each adjustably secured to the sole plate for adjustment of the overall length of the boot, so that two separate adjustment points are provided.
