An inline skate includes a front wheel mount secured to a bottom of a skate boot; a front wheel rotatably secured to the front wheel mount; a rear wheel mount secured to the bottom of the skate boot; a rear wheel rotatably secured to the rear wheel mount; and a shock absorber disposed between the front wheel mount and the rear wheel mount and including two sets of a positioning member secured to the skate boot; a threaded adjustment member disposed through either the rear or front wheel mount; a first bifurcation element through a biasing member and having one end secured to the adjustment member and the other two ends secured to the biasing member; and a second bifurcation element through the biasing member and having one end secured to the positioning member and the other two ends secured to the biasing member.

This locomotion device includes a mechanism suitable for converting the pivoting of a roller into a movement of a pad to an advanced position in which it brakes this roller, this mechanism includes a planetary gear set having: a planetary wheel attached to a sole and the axis of revolution of which coincides with a pivoting axis of the roller and a satellite gear rotated by the planetary wheel about an axis of revolution attached without any degree of freedom to the roller and a pin movable by the satellite gear between: a near position in which it pushes and maintains the pad in an advanced position and a distant position in which it allows the movement of the pad from its advanced position to a retracted position.

The invention relates to a skateboard-type vehicle (1) comprising a platform (2) to which a front wheel (9) support assembly (8) is connected, the front wheel being mounted so as to pivot about a pivot axis (C-C) which is inclined with respect to a mean plane (P2) of the ground (S), the projection of said pivot axis in a plane (P3) orthogonal to the mean plane of the ground forming, with the latter, a forwardly open angle (a) of between 65? and 85?, the front wheel being in contact with the mean plane of the ground at a contact point (17) offset towards the rear by a distance (d) of between 60 mm and 150 mm with respect to a point (18) of intersection of the pivot axis with the mean plane of the ground.

A modular skating assembly for switching between types of skating styles includes a boot that is configured to couple to a foot of a user. A first coupler is coupled to a sole of the boot. Each of a plurality of second couplers is complementary to the first coupler. Each of a plurality of skate modules is coupled to a respective second coupler. The respective second coupler is positioned to couple to the first coupler to selectively couple the skate module to the boot. The improvement is the plurality of skate modules being selectively couplable to the boot, such that a pair of the boots is selectively configurable to enable a particular style of skating, such as in-line skating and roller skating.

A skate (e.g., an ice skate) for a skater (e.g., a hockey player). The skate comprises a skate boot for receiving a foot of the skater and a skating device (e.g., a blade and a blade holder) disposed beneath the skate boot to engage a skating surface (e.g., ice). At least part of the skate boot and optionally at least part of one or more other components (e.g., the skating device) may be constructed from one or more materials (e.g., foams) molded by flowing in molding equipment during a molding process (e.g., injection molding or casting). This may allow the skate (or other footwear) to have useful performance characteristics (e.g., reduced weight, proper fit and comfort, etc.) while being more cost-effectively manufactured. Other articles of footwear are also provided.

Disclosed herein is a retractable inline skate shoe. The retractable inline skate shoe is configured such that: a cavity is formed in the sole of a shoe body; the housing is mounted and fastened in the cavity; a slider is inserted into the housing; a push button is configured to protrude to an outside via a through hole portion formed in a heel of the shoe sole; a number of L-shaped wheel shaft insertion recesses are formed in lower portions of both left and right sides of the slider; a frame is mounted inside the slider; recessed wheel shaft fitting recesses are formed in both side wall surfaces of the frame; two fastening recesses are fastened onto the shoe sole; a guide is inserted into the frame; and the slider containing the frame is fastened into the housing by means of housing fastening plates.
