Abstract: A deceleration device for window shade includes a casing, and a deceleration mechanism movably fitted in the casing with a front end protruded from the casing. The casing can be mounted in a shade roller tube of any window shade that has already been provided with an automatic winding mechanism, and the deceleration mechanism can work with the automatic winding mechanism by gradually increasing the resistance to the winding of a shade fabric around the shade roller tube by the automatic winding mechanism, so as to prevent the shade fabric from being instantaneously lifted to adversely damage the window shade. And, since the deceleration device can be separately mounted to a window shade having an automatic winding mechanism for use, it provides good applicability.

Abstract: The invention relates to a drum brake device (10), which is provided as a wheel brake for a motor vehicle. The invention proposes embodying the drum brake device (10) with a brake belt (14), which is disposed inside a brake drum (12) and can flex in the radial direction of the brake drum (12). Thrust exerted on one end (18) of the brake belt (14) with a simultaneous bracing of the other end (20) of the brake belt (14) causes the brake belt (14) to be pressed against the brake drum (12) from the inside and produces a braking moment. The invention has the advantage that a friction force exerted on the brake belt (14) by the brake drum (12) augments the thrust on the end (18) of the brake belt (14) and thus boosts the braking moment. Another advantage is that the brake belt (14) always rests uniformly against the brake drum (12) over its entire circumference, even, for example, when the brake drum (12) expands due to heating.

Abstract: Improvements made to wheeled skate-skis with brakes usable on most terrains are: a hand controlled hydraulic fluid braking assembly, having a sole, resilient, curved spring, brake shoe, providing performance in comparison with the braking performance of a roadway motor vehicle; a chassis with a foot receiving body portion formed on a convex camber and made of materials which are flexible, under the weight of a person, thereby providing a spring like suspension, and with upwardly directed curved forked ends to position wheel axles higher above the ground to lower the foot receiving body portion, to thereby lower the center of gravity of the sportsperson, while moving on the wheeled skate-skis; a binding which is a combination of an outer shell of a firm material and an inner liner of soft material, which together are adjustable to fit different sizes and types of athletic shoes selected and worn by sportspersons; and a removable mud flap supportable on the binding to deflect water and/or debris thrown by a rea

Abstract: The automatic transmission of the present invention prevents fluctuation of torque transmission through a band brake. In the hydraulic operator for the band brake, a resilient elastic cushion is provided between a rod abutting one end of the band of the band brake and a piston. Any slippage between the band and drum of the band brake will result in oscillation of the rod. However, the elastic cushion absorbs oscillation of the rod, thereby isolating the piston from that oscillation.

Abstract: Disclosed is a brake device for at least one axle of a wheel of a vehicle such as a bicycle for braking a brake drum which is connected to the wheel, having a brake carrier, a shoe element, a brake lever with a cam which is arranged between two shoe ends of the shoe element and is preloaded in that area. The shoe element is connected to the brake carrier by a holder and the cam is connected to the brake lever without a bearing, by means of which it can be pivoted. The brake device according to the present invention has the advantage that it can be produced mechanically in large numbers in a simple manner, its characteristics can be influenced by design measures, and it has a high level of efficiency, so that reduced actuating forces result and possibly simplified actuating elements may be used.

Abstract: A fishing reel drag mechanism includes a spool for a fishing line, a brake drum attached coaxially to the spool, and a resilient circular brake shoe positioned inside the brake drum. The outer diameter of the brake shoe is slightly smaller than the inner diameter of the brake drum. A gap is provided on the brake shoe, and a movable spreader is positioned in the gap. When the spreader is moved to a first position, the brake shoe is in a relaxed position spaced from the brake drum, so that the spool may rotate with zero drag. When the spreader is gradually moved to a second position, the gap is gradually expanded by the spreader, and the brake shoe is gradually expanded against the brake drum. The drag on the brake drum is thus adjusted by changing the width of the gap with the spreader. Grooves arranged concentrically around the brake shoe provide additional compliance which improves smoothness in drag application and the range of drag force provided.

Abstract: A drum-in-hat brake assembly (10) having first (12) and second (14) brake shoes retained on a backing plate (16) by first (18) and second (20) pins connected to the backing plate (16). The first (12) and second (14) brake shoes are aligned on the backing plate (16) by an anchor post (40) and connected to a reverse actuator (26). The reverse actuator (26) receives an input force to respectively move first (42) and second (44) friction pads associated with the first (12) and second (14) brake shoes into engagement with a drum (46) to effect a brake application. The reverse actuator (26) includes a first lever (52) and a second lever (54), each of which have a flat plate (60,76) that extends through an opening (62) in the backing plate (16). A resilient member (90) located in the opening (62) maintains the flat plates (60,76) in a same perpendicular plane with respect to the backing plate (16).

Abstract: A drum-type brake actuator provides increased force transmission efficiency and assembly simplicity. An anchor carries two pistons which are moved to apply a brake shoe by the cooperative operation of a lever and strut arrangement. The utilization of three pivot joints in a simplified mechanism results in high efficiency output.

Abstract: A drum brake assembly including a brake member comprised of a substantially circular shoe having a radially outer face on which at least one lining is mounted. The shoe is made from a high strength resilient material and is of substantially constant cross-section along its entire length. The brake member is arranged to be diametrically expanded by an actuation device on the brake assembly. When the actuation device is released the resilience of the shoe material causes the shoe to diametrically contract. The lining may be machined to a circular form prior to the brake member being fitted to the brake assembly, and that machining is preferably done after the shoe has been expanded a predetermined extent. The disclosure extends to a method of manufacturing a brake member and to a brake member for a drum brake assembly.

Abstract: An anti-theft steering shaft lock includes a longitudinally split elastomeric clutch sleeve, a non-cylindrical cam section on the steering shaft, and a transverse lock bolt bodily shiftable between extended and retracted positions. The sleeve has a right cylindrical outside surface and a non-cylindrical inside surface matching the cam section on the steering shaft. The sleeve fits on the cam section and within a cylindrical bore in a stationary housing on which the shaft is rotatably supported, the bore having a greater diameter than the sleeve so that the steering shaft and sleeve are normally freely rotatable relative to the housing. In its extended position, the lock bolt projects into the slot in the split sleeve to prevent rotation of the sleeve with the steering shaft. The cam section expands and wedges the sleeve against the bore in the housing when the steering shaft is rotated relative to the sleeve.

Abstract: The external sleeve of a slip brake in a torque wrench with a pair of clutches in series is provided with a spiral groove which houses lubricant. "O" rings at opposite ends of the external sleeve cooperate with an internal sleeve to seal in the lubricant. The slip brake of the present invention incorporates an internal split ring or drum which is adjustable to set the desired bias load of the slip brake. However, the split ring or drum is encased in a very thin steel sleeve which is attached, as by soldering, to the split ring. The outer surface of the thin steel sleeve abutts the inner surface of the outer ring and serves as the brake drum. Although the split ring is encased in a thin steel sleeve, the sleeve is thin enough (from about 0.025" to 0.030" thick) so that this sleeve will stretch when the split ring is expanded to increase the bias load on the slip brake.
