This invention relates to a hub mounted shock absorber suitable for use in the wheels of in-line skates or other small wheel transportation devices such as scooters, street skis, etc. and to in-line skates utilizing wheels with such hub mounted shock absorbers. The hub mounted shock absorbers include an outer tube with an elastomer, preferably a low durometer elastomer between the outer tube and the axle of the wheel. The elastomer is prefereably sandwiched between the inner and outer tube with the axle passing through the inner tube. Openings may be selectively provided in the outer tube to further reduce the stiffness of the elastomer and flexure or other appropriate mechanism may be included which result in minimum stiffness for the shock absorber in the vertical direction only. A modified hub design to accommodate the hub mounted shock absorber without changing the overall size of the wheel and a novel tire for the wheel to achieve the same objective, and to also increase wheel stiffness are also provided.

One or more sets of dual brake pads and related assemblies are disposed over and upon one or more wheels of an inline skate. One or more center assemblies are above each brake enabled wheel and center over each wheel. A brake assembly may be secured to a skate boot or to the frame of an inline skate. A brake assembly may attach to a hand control braking system enabling foot free braking. A brake assembly may be attached to one or more center wheels of an inline skate so as to not impede skating maneuvers.

A braking mechanism for a skate, such as an in-line roller skate, has at least one braking wheel disposed transverse to the skate boot. The braking wheel operates a piston which displaces liquid from a piston housing when the piston is caused to travel within the piston housing by the rotation of the braking wheel. The piston and the piston housing are configured such that an increasing resistance is applied to the rotation of the braking wheel as the piston travels within the piston housing. Thus, when the skate boot is turned transverse to the direction of the skater and the angle of the boot is adjusted to cause the braking wheel to rotate, the increased resistance to the rotation of the braking wheel as the piston moves within the piston housing acts to slow the skater. When the piston fully traverses the piston housing, the rotation of the braking wheel is terminated and the skater comes to a stop.

A steerable wheeled device such as an in-line skate or roller ski has a hollow or dish-shaped wheel, a wheel bearing, and a wheel support connecting the wheel to a steering structure that extending substantially within the outer radius of the wheel, and steers as the user's weight is displaced. The device preferably has a side-mounted chassis, and oversize wheel positioned in front and in back of the user's foot. The chassis may contain a damping and centering force mechanism to moderate behavior of the steering or suspension. Brakes such as drum or disk brakes are connected to one or more wheels and preferably actuated, e.g., with a boot-actuated linkage, such that braking occurs upon the user adopting a specific posture. In a preferred construction, the stance shifts weight back and / or down so that deceleration does not occur until the user has assumed a stable stance.

The present invention may include at least one wheel assembly within the wheel recess, such as a plurality of wheel assemblies. Each wheel assembly may include a wheel base attached to the sole, a wheel bracket pivotally attached to the wheel base, and at least one wheel rotatably secured to the wheel bracket. The wheel assemblies include a deployed position in which the wheel bracket is pivoted away from the wheel base and a retracted position in which the wheel bracket is pivoted towards the wheel base.

A wheel for an in-line skate or other wheeled vehicle is disclosed that may be modified to alter the rolling resistance of the wheel. The wheel may be disassembled to change a tire on the outer surface of the wheel to one made of a harder or softer material, and to insert or change a grease of a chosen viscosity into a chamber inside the wheel. The two changes may be utilized singly or collectively to help set the rolling resistance of the wheel. The wheel may be retrofit onto existing in-line roller skates.

In a flat road surface obstacle having a very thin profile and comprised of a malleable structure such as silicone rubber. The obstacle may be combined with a portion of adhesive to attach the obstacle to a play structure surface to be used in combination with wheeled conveyances such as skateboards, roller skates, in-line skates, tricycles and the like. The obstacle may further be used in combination with a skate park structure to provide markers and / or obstacles to be used in game play or instruction.

The present invention relates to an inline frame (1) for an inline skate, designed to mimic the properties of an ice hockey skate blade on ice. The inline frame (1) includes at least one first connection part (8) intended to be connected to a boot (2) and at least two wheels positioned essentially in the inline frame's (1) longitudinal direction. The unique thing about the inline frame is that it includes an upper chassis section (5) and a lower chassis section (6) which via a coupling element (7) are arranged to be rotatable in the inline frame's (1) longitudinal direction, and that the upper chassis section (5) includes at least one first contact surface (11) and that the lower chassis section (6) includes at least one second contact surface (19), where at least one of the first contact surface and the second contact surface is curvilinear.

A training device for inline roller skates includes a training wheel bracket, a training wheel mounted upon the bracket, and means for adjustably mounting the device upon the inline skate. The training wheel is adapted to engage upon the travel surface to compensate for any unbalance of the trainee and to enable the trainee to travel, in a desired direction. The training wheel is adapted to provide a braking action to the roller wheels if the trainee loses balance or the trainee's ankle collapses. The training device serves the dual purpose of providing a means of balancing the skater as well as slowing and braking the forward movement of the skater to control and limit the speed of the skater.

An inline skate with a braking system has a boot and a braking assembly. The boot has a bottom, a rear end and rollers. The rollers are rotatably mounted on the bottom of the boot. The braking assembly is pivotally mounted on the bottom near the rear end of the boot. When the braking assembly abuts the ground, the braking assembly pivots toward the rollers of the boot to stop the rotation of the rollers of the boot so that the ground does not have a trace of the stain. The total length of a combination of the boot and the braking assembly can be short so that a skater has a smooth movement when the skater is skating and the inline skate has better control. The inline skate with shorter length has a neat appearance.

The present invention relates generally to an improved structure of inline skates, which provides a cushion, a wheel with a gearwheel on its side, and a pawl assembly. By pressing down the weight, the wheel with gearwheel on its side occludes the pawl assembly, which stops the wheel with gearwheel on its side from rolling one-wayly. Thereby, the improved structure of inline skates is more ergonomic and exercise injuries can be prevented. In addition, a brake is provided for providing shock absorption and more powerful acceleration. Besides, automatic support upright is also provided for avoiding tumbles.
