Abstract:
A brake assembly for inline skates having a boot portion (10) with right and left downwardly directed frame members (12, 13). The frame members (12, 13) support at least three axles. Right and left carrier plates (25, 28) are positioned along an inner face of the downwardly directed frame members (12, 13). At least two diabolos (31, 32) are supported by the right and left carrier plates (25, 28). The diabolos (31, 32) each contact two wheels (18, 19, 20, 21) and are forced outwardly to provide a friction rubbing action against the carrier plates (25, 28) when the carrier plates (25, 28) have moved from a disengaged position to an engaged position.
Abstract:
A skateboard including: a central rod unit; a first footplate installed to an end of the central rod unit to be rotatable on a vertical axis; a plurality of first casters installed to be rotatable, independent from the first footplate; a second footplate installed to another end of the central rod unit to be rotatable on another vertical axis; and a plurality of second casters installed to be rotatable, independent from the second footplate. A user may move forwards and backwards by putting both legs on footplates and walking forward and by alternating the both leg forward and backward. Also, since the first and second casters may independently rotate, rotating 360 degrees in place may be performed.
Abstract:
A runner assembly (10) housing a blade (30) for an ice skateboard (12) and rotatably connected to a truck assembly (16) mounted to a bottom board surface (18) thereof has biasing means (40) connected, such as an elastic cord (44), for biasing the runner assembly (10) towards a neutral position (54) in which blade (30) is substantially parallel to bottom board surface (18) of ice skateboard (12) and faces away therefrom. Runner assembly (10) has connecting means (46) on body ends (32) of a body (26) thereof and to which body connecting means protrusions (56), such as connecting knots (58).in elastic cords (44), may be attached. Body (26) also provides runner surfaces (60) upon which body (26) may slide when body ends (32) of body (26) are moved away from board (12) and is shaped to reduce wear on biasing means (40). Biasing means (40) is further removably connectable to skateboard connecting means (106, 114) disposed on board (20) of skateboard (12) or on truck assembly (16).
Abstract:
An all-terrain board (10) has a platform (12) which is supported on two wheel axles (24, 26) connected to the platform by pairs (34, 36) of flexible links. The links in each pair are spaced on either side of a longitudinal axis (18) of the platform. The links are biased so that they have a horizontal dimension when the platform is loaded with a rider. When the rider tilts the platform, this shortens the horizontal dimension on the tilted side, and lengthens it on the other, so that a steering effect is created. The biased links also provide the board's suspension.
Abstract:
The present invention relates an in-line skate having springs mounted. The in-line skate having springs mounted comprises a boot (10) worn by a user; a frame (20) for rotatably supporting a plurality of wheels (30), wherein the frame has a pair of right and left through-holes formed at the front and rear, respectively, and springmounting grooves each stepped from the through-holes; support shafts (52) disposed downwardly from the boot, wherein each of the support shaft is inserted into each of the through-holes so that the support shafts are not deviated; and a plurality of springs (50) and (50a) disposed to surround the support shafts and inserted into the spring-mounting grooves, whereby elasticity is provided between the bottom of the boot (10) and the frame (20). It is preferred that the modulus of elasticity of the spring disposed at the front is higher than the modulus of elasticity of the spring disposed at the rear.
Abstract:
A wheeled board (1) for carrying a rider holding on to a kite for propulsion. The board has a support platform (2) on which the rider stands, and wheel sets (3, 4) attached at either end of the board. A pair of foot retaining straps (18, 19) are provided on the support platform, spaced longitudinally from each other, the arrangement being such that each foot of a rider will be located laterally asymmetrically with respect to the longitudinal axis (5) of the board with a bias towards the side of the longitudinal axis of the board on which the heels are positioned. The support platform is laterally asymmetrical, with the major part (13) of the support platform being on the heel side. On the heel side, the support platform has a profile which is generally convex, and on the other side of the longitudinal axis the support platform has a profile with a region (15), extending generally between the positions of the toes of a rider, which is concave.
Abstract:
This invention presents skateboard apparatus with higher turning capabilities. The skateboard apparatus comprises a board for supporting a user, a first wheel assembly coupled near the back end and a second wheel assembly coupled near the front end. The wheel-supporters in the second wheel assembly are welded to worms and a nut is attached to the lower surface of the board. When the user gives pressure on a certain side of the board the nut tents to move downwards rotates the worm and changes the rotational direction of the wheels.
Abstract:
L'objet de l'invention est un châssis à déformation contrôlée pour un engin de glisse, notamment pour une planche à roulettes, caractérisé en ce qu'il comprend une structure (10) avec une platine centrale (12), une platine avant (14) et une platine arrière (16), ces platines comportant un agencement en caisson avec un intrados (12-1, 14-1 et 16-1) et un extrados (12-2, 14-2 et 16-2).
Abstract:
The independent wheel suspension system (100) of the present invention provides an optimal shock absorption in which the shock absorbent device (30) is easily activated by the weight of the user to provide for an improved maneuverability of the movable structure (B). The system (100) includes a truck (10) for mounting on the movable structure (B), a swing arm (12) pivotally connected to the truck (10) for rotation around a horizontal axis (H) between first and second limit positions, at least one wheel (14) rotatable on said swing arm (12), a shock absorbent device (30) with a shock absorber (34) and a guide (33), and a user accessible tension adjuster (35) for adjusting the tension of the shock absorber (34) in accordance with the desired stiffness for use or preference. The guide (33) has a first end (36) pivotally connected to the truck (10). The shock absorber (34) is mounted coaxially on the guide (33) and has opposite ends abutting the swing arm (12) and a free second end (38) of the guide (33) respectively, whereby the shock absorbent device (30) can freely follow rotation of the swing arm (12) between the limit positions. This independent suspension system (100) can be optimally applied to any device mounted on roller(s), or wheel(s), that would benefit from such an adjustable independent suspension system.
Abstract:
Disclosed is a shoe with roller blade assembly. The shoe has a shoe body which has a cavity in an outsole thereof. A housing is accommodated in the cavity of the shoe body. An underside of the housing is opened and assembling slots are horizontally formed in lower inner ends of both sidewalls of the housing. A roller assembly is movably accommodated in the housing. The roller assembly includes a frame and a plurality of rollers arranged in a lower end of the frame in an in-line pattern. A stopper is provided for restricting the roller assembly from being completely withdrawing from the housing. A locker is movably coupled to the assembling slots of the housing such that a part of the locker is protruded through a rear portion of the outsole of the shoe. The locker selectively makes contact with an upper end or a lower end of the roller assembly so as to support the roller assembly. A brake is mounted on a rear end of the outsole of the shoe. A user wears the shoe with roller blade assembly as ordinary shoes in ordinary times by accommodating a roller blade in the outsole of the shoe body and uses the roller blade by withdrawing the roller blade from the outsole of the shoe body as needed. Accordingly, it is not required to separately purchase the shoes and the roller blade.
