The present disclosure relates to a stroller comprising: a sheet portion including a sheet; a support frame including an upper support frame supporting the sheet, a lower support frame rotatably connected to the upper support frame by a hinge portion, and a frame support that maintains a fixed state between the upper support frame and the lower support frame; and a moving structure to which the support frame is detachably connected, the moving structure including a guide frame that allows the lower support layer to fold and support and is extended in the length direction, a drive frame including a rear wheel coupling portion having a front wheel coupling portion connected in a ‘¬’ shape to the front part of the guide frame and a rear wheel coupling portion having coupling shaft portions formed on both sides of the rear end of the guide frame, a front wheel supported by a support fork to be installed on the front wheel coupling portion, and a rear wheel installed on the rear wheel coupling portion through a rear wheel connecting shaft.

A telemark ski binding has a toe retainer pivotally coupled to a base. A lock assembly of the binding has an actuator assembly. The lock assembly is adjustable between a locked configuration and an unlocked configuration. The binding further has a heel retainer rotatably coupled to the toe retainer. When the lock assembly is in the unlocked configuration, the toe retainer is unlocked, and the toe retainer and heel retainer are both rotatable together substantially inline, relative to the base, around a first center point. When the lock assembly is in the locked configuration, the toe retainer is locked, and the toe retainer is restrained from rotating relative to the base. The heal retainer is rotatable relative to the toe retainer around a second center point. The second center point is at a different location from said first center point.

The invention relates to a ski binding including a front jaw and a rear jaw for holding the sole of a ski boot. The front jaw includes a base, via which the front jaw can be connected to a ski, a first holding device for connecting the boot to the ski at the front end of the boot for ascending, and a second holding device for connecting the ski boot to the ski at the front end of the boot for descending. The second holding device exhibits a first configuration for descending, in which the second holding device is in contact with the front end of the sole of the ski boot, and a second configuration for ascending, in which the second holding device is out of contact with the front end of the sole of the ski boot.

An apparatus for receiving one or more activity attachments including a deck having one or more openings along a long axis of the deck and between the top surface and the bottom surface of the deck. Each of the one or more openings having a circular aperture for receiving an accessory of a set of accessories. Each accessory of the set of accessories providing an activity for a user of the activity. Each accessory having an attachment platform configured to attach the accessory to the board. The attachment platform having a locking mechanism to engaging with a complementary locking mechanism of the board.

Roller-skates/sneakers with two pairs of separable wheels, by which the problem of their alternative adjusting for walking or roller-skating is solved, and which are at the same time safe, maneuverable, practical and simple to manufacture. The roller-skates consist of sneakers, which are laced with laces, an insole and two pairs of wheels separably fixed in the insole. The insole, which follows the shape of the foot and contains the front and rear axle and forms the load-bearing construction, is built into the lower part of the sneaker inside the sole. The wheel consists out of the middle plate lined with silicone rubber, an interchangeable mask, two bearings on the rims of central hollow part of the wheel, as well as two washers made of steel with two lids on the side of the wheel facing the sneaker.

A roller blade ice wheel assembly for using roller blades on ice includes a plurality of blade wheel apparatuses each comprising a wheel body having a central wheel aperture, a pair of wheel sidewalls, and a wheel edge. The wheel edge is less than 0.5 cm. At least one bearing is coupled to the wheel body. The bearing receives an axle of a roller blade through a bearing aperture and the wheel aperture. Each of a plurality of spacers has a central spacer aperture to receive the axle of the roller blade. The plurality of spacers is positioned on both sides of the bearing to occupy space up to a wheel frame of the roller blade. The width of the blade wheel apparatus is dimensioned to equal the width of a wheel of the roller blade that is being replaced.

A caster board can include a front platform section connected by a torsion bar or other neck portion to a rear platform section. The caster board can be convertible between a first configuration in which the caster board has three wheels, and a second configuration in which the caster board has two wheels. In the first configuration, the rear platform section can be supported by two wheels laterally offset from a longitudinal axis of the caster board. In the second configuration, the rear platform section can be supported by one wheel aligned with a longitudinal axis of the caster board. The rear platform section can include at least three mounting locations configured to have caster assemblies installed therein.

An athletic shoe configured for use in sports such as but not limited to floor hockey wherein the shoe of the present invention is operable to provide a rolling lateral movement for the wearer. The shoe of the present invention includes an upper bound to the sole wherein the sole includes sidewalls and a bottom surface. Formed in the bottom surface of the sole is the roller assembly. The roller assembly includes a cavity being defined by four walls. The cavity has a wheel member mounted therein on an axle that is mounted between the front wall and rear wall of the cavity. The mounting of the axle provides the lateral rolling motion. The wheel member is movable between a first position and a second position. In the second position a portion of the wheel member extends beyond the bottom surface of the sole.
