Patent number: 4819501Abstract: An improved self-adjusting mechanism for a cable-operated vehicle brake is disclosed. The operating lever is pivoted about an axis on a frame member which carries a fixed sector. The lever carries a first pawl, which is adapted to releasably hold the operating lever in position with respect to the frame, and a second pawl which locks the lever to a sheave sector fixed to a sheave which winds up the brake cable upon pivoting of the lever. A third sliding pawl is mounted on the sheave sector. When the operating lever is rotated beyond a predetermined degree in setting the brake, the sliding pawl abuts a stop on the frame. This moves the sliding pawl with respect to the sheave sector. When the handle is subsequently returned to its rest position, the sliding pawl allows a limited amount of rotation of the sheave sector with respect to the lever, which occurs due to tension exerted on the brake cable by the brake shoe return spring.Type: GrantFiled: April 12, 1988Date of Patent: April 11, 1989Assignee: Handy & Harman Automotive Group, Inc.Inventors: James R. Kraus, Eugen O. Rothacker

Patent number: 4793204Abstract: A tilt and telescope steering column is disclosed in which a single control member operates the lock and release of a tilt lock mechanism and a telescope lock mechanism. Both lock mechanisms include pivotally mounted pawls having teeth which interfit with teeth on an associated housing assembly to lock the column in its adjusted position. The pawls are movable in opposite directions from their respective locked positions to release positions in which adjustment of the steering column is permitted. A control member is mounted for movement in two directions and operates in one direction to release one lock system and in the opposite direction to release the other lock system. Spring means normally maintain the locking pawls in their locked position and also maintain the control member in its neutral position. In one embodiment, a single spring functions to normally maintain both lock mechanisms in their locked position and also normally maintains the control member in its neutral position.Type: GrantFiled: November 25, 1987Date of Patent: December 27, 1988Assignee: Douglas Components CorporationInventor: Duane T.

Patent number: 4712759Abstract: A lock structure for a seat slide device for a vehicle seat having a first and a second rail which are parallel to each other and mutually slidable, and in particular to such a lock device which can lock up at any slide position. This can be accomplished by varying the pitch of the lock holes and the lock teeth from each other as opposed to the case of conventional lock structures in which lock teeth and lock holes are provided at the same pitch. The various approaches proposed by the present application include the use of the principle of a vernier caliper, varying the phase relationship of the lock teeth relative to the lock holes, and using evenly spaced lock teeth in combination with lock holes provided at a pitch which is a multiple of the pitch of the lock teeth.Type: GrantFiled: May 1, 1986Date of Patent: December 15, 1987Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Takayuki Sugama, Hiroshi Tabata, Tadanori Honda

Patent number: 4543850Abstract: A neutral lock mechanism for a direction and speed control pedal. Forward or down-toe motion on the pedal produces forward movement of a vehicle and rear, or down-heel, motion produces rear movement, while increased displacement of the pedal in either direction will produce an increase in speed. The neutral lock mechanism includes a latch pivotally connected to the pedal and spring loaded to a latching position in which the latch will engage the floor plate of the vehicle and prevent pivotal movement of the pedal. A lever is connected to the latch and projects upwardly through an opening in the pedal. The operator's foot, when in a normal operating position, will depress the lever and release the latch while mere accidental engagement of the operator's foot with the pedal will not release the latch and will retain the pedal in the neutral lock position.Type: GrantFiled: June 20, 1983Date of Patent: October 1, 1985Assignee: Ransomes, Inc.Inventors: Richard D. Bednar, James K. Hampton

Patent number: 4519270Abstract: A foot-operated device for controlling a parking brake wherein a parking brake pedal is locked in its operated position through engagement of a pawl member with ratchet teeth. The pawl member is pivotally connected to the brake pedal, and the ratchet teeth are formed on a sector or bracket fixed to a vehicle frame on which the brake pedal is pivotally supported. The parking brake is released when a pedal pad pivotally connected to the brake pedal is pivoted on the pedal and the pedal is depressed. The pedal pad is operatively connected by a lever to the pawl member which is normally held in engagement with the ratchet teeth by a first spring member. The lever is pivotally connected to the brake pedal, biased by the first spring member and engageable with the pawl member to transmit a biasing force of the first spring member to the pawl member so that the pawl member engages the ratchet teeth.Type: GrantFiled: November 10, 1982Date of Patent: May 28, 1985Assignee: Toyota Jidosha Kabushiki KaishaInventors: Hiroshi Kawaguchi, Shuho Nishina
