Abstract: Handbrake assembly for the wheelbarrow is normally "on" and comprises a brake lever pivoted to the wheelbarrow undercarriage. One end of the lever carries a shoe head, the other a fixture for the drive cable of a Bowden wire leading to a bicycle-type handbrake. A spring presses the brake shoe end of the lever so that it engages the wheel.
Abstract: A braking force distribution linkage for a muscular energy-actuated parking brake system of a motor vehicle, in which the braking force is transferred at least via control cables both to one gear of the vehicle's transmission and to the wheels of at least one driven vehicle axle, the wheel brakes on each vehicle axle being respectively articulated via a compensation element. A linkage, lever and balance arm arrangement ensures a sufficient parking-hold effect on a road surface with differing nonskid properties, even in the event of failure of a portion of the braking system.

Abstract: A drum brake device is provided in which a stroke before effectuating the parking brake effect of the brake shoes is restricted so that any disconcerting feeling to the driver and any delay in effectuating the parking brake when in an emergency situation are eliminated. The drum brake device includes a pair of the brake shoes 20, 21, a pivot lever 36 pivotally provided at one of the two brake shoes 21, a shoe clearance adjustment device provided between one end of the pivot lever 36 and one end of the brake shoe 20, and a strut provided between the other end of the pivot lever 36 and one end of the brake lever 28, wherein the braking force is transferable between the two brake shoes 20, 21 through the connection with the pivot lever 36. This produces a duo-servo type of brake device. The brake shoe 21 functions as a trailing shoe in which the lining wears slower when the service brake is in operation.

The rotation aperture provides for rotation of the device when a tool is inserted therein and when a first cable is inserted into the cable receiving aperture of the first elongate cavity and a second cable is inserted into the cable receiving aperture of the second elongate cavity, thereby creating an over-center lock by moment of force that maintains tension on the first and second cables.
Abstract: A parallel vehicle includes three main control systems. The first controls the position and angle of the two parallel wheels relative to a fixed chassis, enabling the wheels to be moved outwardly and inwardly and the camber varied for greater stability, aerodynamic effect, or turning. This first system may be mechanically or hydraulically actuated, but preferably is controlled by a pair of control members whose position relative to the chassis corresponds to the desired position of the wheels relative to the chassis in order to provide an intuitive control mechanism. The second system is the propulsion system which may, for example, take the form of a derailleur drive of the type used in bicycles, but with power from the propulsion system being transmitted to the wheels via a rotating cable and individual gearboxes for each wheel which permit the direction of the wheels to be reversed.
Abstract: In order to improve an electrically actuatable automotive parking brake with mechanical emergency actuation, the brake pads (52, 54) of the parking brake, which may be either a disk brake or a drum brake, can be applied or released via gear arrangement (100) arranged within or at the brake. The gear arrangement (100) has one power input and one power output, with the power input being coupled with the one end of a flexible shaft, the other end of which being arranged remote from the brake can be coupled with a manual crank, in order to be able to actuate the parking brake mechanically in the case of a failure of the electric actuation.

Abstract: A parking brake assembly for connecting a cable to a lever. The lever has a generally flat base member pivotally mounted on the second brake shoe with a first end connected to the first brake shoe and a second end joined to a brake cable. The cable is located in a helical guide spring retained in a spring support which extends from the base member. A front face on the ramp is initially engaged by a tip of the cable while the slot forms a guide to allow an input force to move the tip over a lip on the end of the second tine. Once the tip has moved past the second tine, the cable tries to straighten out to eliminate any flexure induced by moving up the ramp by snapping into the slot and become aligned with the helical spring. A force applied to the cable which pulls the tip into engagement with a rear face on the ramp to complete the connection between the cable and lever. The projection assures that the cable remains located in the slot no matter how far the tip moves past the lip on the second tine.

Abstract: Lever-mounted brake pads are applicable to two non-swiveling wheels at the rear of a hand truck. The pads are normally spaced away from the wheel treads by return springs. A foot pedal at the front of the truck is operable between two positions, one of them being a "brake off" position, and the other being a "brake on" position. Cranks are connected to the pedal and have links and cables associated with them and with the brake pad levers whereby the pedal, operating through the cables, is useful to either simultaneously apply both brakes in one pedal position, or simultaneously release both brakes in the other pedal position. The return springs keep the cables taut when the brakes are off. An over-center arrangement on the cranks and links, together with an appropriately positioned stop in the "brake on" pedal position self-energizes to keep the brakes on until intentionally released.

Abstract: The braking system for an in-line roller skate is operated by a cable attached to a trigger type of lever in a hand grip. This braking system is improved by incorporating an arrangement for allowing the skater to quickly attach or detach the end of the brake cable at the skate. Locking of the brakes to permit walking without rolling is obtained by incorporating a latch mechanism in the gripper handle. The gripper handle is storable by a snap-on type retainer for the belt or pocket of the user which permits the brake cable to move without unintentionally releasing the retainer from the person of the skater while avoiding kinking and twisting of the cable in response to the normal skating motions of the skater. Retention of the cable relative to the thigh of the user is realized by a belt or other attachment arrangement including a Velcro type of clip.

Abstract: A universally rotatable nipple for a brake cable includes a socket device having a hemispherical body and a first tube extending from a periphery portion of the hemispherical body and a rotatable device including a sphere and a second tube extending from a periphery portion of the sphere. The sphere of the rotatable device is rotatably received in the hemispherical body of the socket device with the second tube being in communication with the first tube, thus allowing a brake cable to be guided from the second tube through the first tube. The rotatable nipple responds to the pulling from the brake cable and rotates in an appropriate direction to release the friction between the nipple and the brake cable.
Abstract: A brake-adjusting system in particular for motor-vehicle handbrakes which allows quick adjustment of the handbrake using two freewheel units of which one is employed for driving-conditions proper. As a result unintended brake adjustment shall be prevented.
