  • Patent number: 8979096
    Abstract: 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.

  • Patent number: 7367568
    Abstract: A mechanical brake system for inline skates that utilizes all four wheels for braking. The brake is applied by the skater straightening the leg, or both legs if there are brakes on both skates, to a predetermined adjustable position. This causes the adjustable and spring loaded trigger rod, mounted on the pivoting ankle support behind the heel to push the brake lever that extends from behind the heel on both sides of the frame to the front where it is hingedly attached to move downwards. At the mid-point of the skate the brake rail positioned above the wheels and extending the whole length of the skate is connected to the brake lever. The downward movement of the brake lever and brake rail causes the brake rail to contact the wheels causing friction and thereby braking in direct proportion to the force by which the skater is straightening the leg(s). The brake rail is inflexible and shaped to fit the curvature of the wheels thereby facilitating even wheel wear both regarding shape and diameter.

  • Patent number: 6955360
    Abstract: 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.

    Abstract: A braking system preferably for an in-line skate includes a brake pad mounted to a forward end of a skate frame and an elevated front wheel attached to the skate frame by two pivot arms. The pivot arms are biased forward which is in a clockwise direction with respect to their pivot point. When skating normally, the pivot arms bias the wheel against the brake pad, but the wheel is elevated from the skating surface and thus the brake is not engaged. When skating in a rearward direction, or desiring a push start, the skater rotates the toe portion of the skate downward and raises the heel. The front wheel will engage the skating surface and the reaction force on the wheel due to friction between it and the skating surface will urge the wheel forward and increase the contact pressure between it and the brake pad.

  • Patent number: 6367818
    Abstract: An in-line roller skate including a soft, pliable, and comfortable shoe body having structural foot support components positioned in selected strategic areas such as the ball, heel and ankle areas. The shoe body may be made of a material that allows air circulation for coolness. In one embodiment, the structural components are made of semi-rigid plastic which may be heat moldable to conform to the user's foot. The sole of the shoe may also include heat moldable materials so that it can be anatomically formed to the user's foot. The shoe is mounted on a frame that supports a plurality of in-line roller wheels and includes structure for easily removing and replacing the wheels. The shoe-frame connection may be laterally and longitudinally adjustable. A speed control or brake, which applies a frictional force downwardly onto some or all of the in-line roller wheels, is mounted on the frame. Canting adjustment is provided to allow the ankle support to be canted laterally or longitudinally.

  • Publication number: 20010054803
    Abstract: An in-line roller skate with a braking device is disclosed including a certain number of wheels (11) disposed longitudinally between two plates of a frame (22) of the skate. A control lever (1) articulated at the rear of the boot about a pivot shaft (19) can be actuated by a backward movement of the skate cuff. When rotating, the lower part (2) of the lever (1) pushes a rod (3) forwards and lengthways against return means (10a, 10b), said rod carrying brake pads (5) in an equal number to the number of the discs (6) placed on the wheels 8 (11) and ramps (7a, 7b) co-operating with complementary parts of the frame guiding the rod in order, during a forward movement, to bring the pads into contact with an upper part of the rotating discs. The ramps are positioned between two wheels so as to assure gentle and gradual braking.

  • Publication number: 20010006282
    Abstract: A series of molded nylon or hard plastic pivotable wheel supports allow independent movement of each wheel. Resilient elastomeric shock absorbing bumpers are positioned between the wheel supports and the mounting plate attached to the sole of the skate boot. In the alternate embodiment a front and a back wheel support or truck are each attached to the sole plate by a bolt attached between holes in front and back side flanges extending downwardly from the sole plate, which holes may be slotted vertically and horizontally for greater movement. A rigid truck link interconnects the two trucks at pivot points which may coincide with inner wheel axle holes in the trucks. Each truck supports an outer wheel and preferably one inner wheel. A wedge-shaped compression bumper fits in a V-shaped cradle in each truck. Each bumper is compressed against the sole plate as each wheel encounters a bump and is elevated to pivot the truck.

  • Patent number: 6254109
    Abstract: An anti-lock braking system for in-line skates comprises a brake shoe adjacent each wheel of the skates. A skate boot has an articulated cuff for initiating braking action when the cuff is pivoted in a backward or forward direction as selected. Pivoting the cuff functions to move the brake shoes into braking contact with the wheels. Springs are connected to the brake shoes via a cable system to bias the brake shoes out of contact with the wheels and thus to prevent brake lock-up.
