Abstract: A method of manufacturing a meter roller for an agricultural metering system includes stretching a sealing ring. The method also includes disposing the sealing ring between a first ring of a spindle and a second ring of the spindle. The first ring and the second ring are rigidly coupled to a driven shaft of the spindle, and the driven shaft is configured to engage a drive shaft to facilitate rotation of the spindle. In addition, the method includes enabling the sealing ring to contract such that an outer diameter of the sealing ring is less than or equal to an outer diameter of the first ring and an outer diameter of the second ring.

Abstract: A system for gait training which includes a height-adjustable rolling platform for attaching to the foot with or without a shoe, on the affected side of a subject. When the subject shifts their body weight away from the affected side, the platform is capable of forward and backward movement to follow the swinging movement of the leg. When the subject shifts their body weight to the affected side, a passive braking system arrests any further movement of the affected limb.

Abstract: A specially formed ball shaped disc 40 to 50 mm in diameter to be utilized on the PIC® inline skate, U.S. Pat. No. 5,738,360, to allow for extreme jumps, spins, and footwork moves in the sport of inline figure skating. The ball pick disc is made of molded rubber or synthetic material. The purpose of the ball pick is to provide extreme deep edges for enhanced spins, jumps, and footwork common in the sport of inline figure skating while protecting the skate frame from scraping. The ball shape is slotted to fit around the frame thus protecting the frame from scraping and allows the skater to achieve extremely deep edges. The ball shape provides 180 degrees of surface allowing the skater unlimited toe-in angles. The configuration of the disc allows the ball pick to be reversed to extend wear.

Abstract: A skate sole assembly has a boot bracket, a frame, two cushioning bearings and two axles. The frame is mounted under the boot bracket and has an arcuate plate and two outer supporting arms. The arcuate plate has two inner supporting arms corresponding to the outer supporting arms. The cushioning bearings are embedded respectively in connecting ends of the outer supporting arms and respectively receive connecting ends of the inner supporting arms. Each axle is rotatably mounted through the connecting end of one inner supporting arm, the connecting end of one outer supporting arm and one cushioning bearing. The frame is made of rigid material to stabilize the motion of a user wearing skates which are assembled from the skate sole assemblies. The cushioning bearings provide a cushioning effect.

Abstract: A brake assembly for a skate of the type having parallel rails connected to the bottom of a boot. The skate brake bracket for mounting outside the rails and a brake wheel mounted to the skate brake bracket. The tension of the brake wheel may be adjusted.

Abstract: A roller skate has a frame formed of a short length of sturdy, generally rectangular channel material having two opposed side walls and a sole plate or floor extending therebetween. A large diameter wheel is secured to each end of each side wall, to define a widely spaced rectangular wheel array providing a stable skate platform. The high attachment of the large diameter wheels places the sole plate immediately adjacent the underlying surface when the wheels are resting on that surface, for greater stability. Instep and heel straps extended from single central attachment points along each side wall, with the present skate being essentially longitudinally and laterally symmetrical. Provision may be made for vertical and/or lateral adjustment of the wheels relative to the skate frame, if so desired.

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.

Abstract: A skateboard comprises a board, two wheel units attached to an underside of the board, and a braking member attached to the underside of the board. The braking member includes at least one metallic braking block that is in contact with ground during braking. The metallic braking block sparks during braking to provide an amusement effect.

Abstract: An in-line roller skate in accordance with this present invention includes at least four integral independent suspension system aligned under the chassis platform having all forks axles pivotally in forward motion and opposite direction from each other. The integral independent suspension system all parts and components are integrated in a body-frame, includes at least two independent shock absorber mechanisms in which the front shock absorber suspension mechanisms interconnects with the rear shock absorber secondary mechanisms, in which the rear shock absorber mechanisms support the pivotally forks axles and wheel system. The main chassis system supports the front brake and central rolling-brake. The integral independent suspension and the removable boot systems are interconnected with the chassis system trough a plurality of removable fasteners. The removable boot supports the front and rear anatomical-frame structure and the rear integral independent suspension support the main brake system.
