An improved handle cover apparatus is a handle cover and extension that attaches to the hand brake handle of a wheel chair to provide padding, improved comfort, and greater leverage to allow the brake to be applied more easily and to eliminate the arthritic pain associated with operating the current, short, wheel chair brake handles.

An actuator for a motor vehicle functional unit includes a force transmission unit transmitting an actuating force to an actuating member and being displaced by a measuring travel in a force transmission direction. A force measurement device detects an actual value of the actuating force and includes a spring acting in the force transmission direction, having resilient action counter to which the force transmission unit is displaced and being tensioned by the actuating force over a resilient excursion, a micro switch having smaller switching travel than the measuring travel and being actuated upon displacement of the force transmission unit if the actuating force reaches the actual value, and a stop element for actuating the switch. The switch or element are coupled to or fixed relative to the force transmission unit and the switch and/or element are resiliently supported to compensate for a difference between the switching and measuring travels.

A powered balancing mobility device that can provide the user the ability to safely navigate expected environments of daily living including the ability to maneuver in confined spaces and to climb curbs, stairs, and other obstacles, and to travel safely and comfortably in vehicles. The mobility device can provide elevated, balanced travel.

A bicycle control device includes a housing member, a control lever member, a shift-operating mechanism and a hydraulic fluid pressure generator. The housing member has an attachment part for attachment to a handlebar, and a grip part extending longitudinally between first and second ends of the grip part. The attachment part is provided on the first end of the grip part. The attachment part is provided on the first end of the grip part. The control lever member is pivotally provided with respect to the housing member. The shift-operating mechanism is supported by the housing member. The shift-operating mechanism includes a control cable attachment part that is configured to be coupled to a shifting device by a control cable. The hydraulic fluid pressure generator has a cylinder provided in the grip part of the housing member, and a piston movably disposed within the cylinder by movement of the control lever member to generate fluid pressure for controlling a braking device. The cylinder is disposed closer to the second end of the grip part than the shift-operating mechanism.

An improved master cylinder for use with a hydraulic clutch or hydraulic brake system. The master cylinder has a master cylinder body defining a bore. A piston is configured to slide in the bore when an actuation lever is compressed by a user. Sliding of the piston as a result of the depression of the lever causes the piston to depress a spring and to increase hydraulic pressure in the hydraulic line leading to the brake or clutch. A spring is configured to return the piston when pressure is released from the actuation lever. The master cylinder body in some embodiments is configured for lateral position adjustment relative to a mounting bracket. In some embodiments the master cylinder has a reservoir. The reservoir can be oriented at a tilted angle relative to the body of the master cylinder. In further embodiments the master cylinder has an outlet nut that is configured for attachment to the hydraulic line. The outlet nut is configured such that removal of the outlet nut allows for access to the bore, including the spring and piston.

Provided is a hand brake, comprising a hand wheel (4), a chain (5), an enclosure (1), a drive shaft assembly (3) which is disposed in the enclosure (1), bull gear (13), and base assembly; the hand wheel (4) is connected to the drive shaft assembly (3), one end of the chain (5) is fixed to the bull gear (13) by means of rivets, and the main shaft of the bull gear (13) is a chain winding shaft (2). The hand brake further comprises a limiting device disposed on the chain winding shaft (2) between the bull gear (13) and the base (22); the limiting device comprises a first bearing (10), a torsion spring (11), a guide plate (9), and a guide plate holder (23). Installing the hand brake not only prevents the problem of the chain interfering with the movable pulley when the hand brake is deployed and thus affecting the performance of the hand brake, but also provides for a better appearance.

A method for the operation a parking brake of a motor vehicle that comprises at least one wheel brake device, wherein the wheel brake device comprises an electric motor that can be activated for its actuation and that drives a spindle for the displacement of a brake piston between a clamping position and a release position, wherein for the calibration of the parking brake the electric motor is activated in order to move the brake piston into the release position in a first step and from the release position into the clamping position in a subsequent second step. It is provided that in the second step a power supply of the electric motor is interrupted during the displacement of the brake piston in a no-load phase (II) and at least one motor parameter of the electric motor is determined depending on a coasting behavior of the electric motor.

A manual brake structure is employed to stop a bicycle or motorcycle and contains: a casing, a body, a roller, a first brake line, a second brake line, and a third brake line. The casing includes a first cap and a second cap. The body is housed in the casing and includes a first accommodation portion and a second accommodation portion having two first apertures. The roller is housed in the first accommodation portion and includes a trench. The first brake line is bent in half, fitted into the trench, and connected with a first brake and a second brake of the bicycle or motorcycle. The second brake line includes a first stop block and couples with a first controller of the bicycle or motorcycle. The third brake line includes a second stop block and couples with a second controller of the bicycle or motorcycle.

A control device for a vehicle includes an operation unit, an operation-unit sensor, a motor, and a driving force controller. The operation-unit sensor is configured to detect an operation-unit operation amount. The operation-unit operation amount is an amount of operation of the operation unit. The motor is capable of generating a negative driving force for decelerating the vehicle. The driving force controller is configured to cause the motor to drive a wheel of the vehicle with the negative driving force on a basis of the operation-unit operation amount, and to derive the negative driving force in accordance with an initial time change. The initial time change represents an amount of change in the operation-unit operation amount per unit time relative to an operation-unit operation amount at an initial position of the operation unit.
