Patent number: 6363811Abstract: Apparatus for selectively applying tension to a parking brake cable that includes a pulley for coupling to the cable and having a cable groove that is non-circular about an axis of the pulley. A lever is coupled to the pulley for rotating the pulley in one direction about its axis, and thereby winding the cable into the groove to apply tension to the cable. A clutch is coupled to the pulley to prevent reverse rotation of the pulley, and a release mechanism is coupled to the clutch for releasing the clutch and thereby releasing tension in the cable. The non-circular groove has a maximum radius where the cable is wound into the groove upon initial operation of the lever, and a decreasing radius thereafter. In this way, force is applied to the parking brake cable at maximum rate of change upon initial actuation of the lever, increasing at a lower rate as the lever is further depressed.Type: GrantFiled: March 7, 2000Date of Patent: April 2, 2002Assignee: Ficosa North American Corp.Inventor: Sergio Saldaña

Patent number: 6343525Abstract: A locking mechanism selectively prevents rotational movement of a handle relative to a frame. The locking mechanism includes a fork member having first and second ends and pivotally attached to the frame member at a pivot located between the first and second ends; a first locking device located at the first end of the fork member; a second locking device located on the handle and engaging the first locking device on the first end of the fork member for preventing rotational movement of the handle; an elastic member for biasing the first and second locking devices into engagement; and an attachment mechanism located at the second end of the fork member. A tension force on the attachment mechanism pivots the fork member about the pivot member to disengage the first and second locking devices and allow the handle to rotate relative to the frame.Type: GrantFiled: November 24, 1999Date of Patent: February 5, 2002Assignee: Xerox CorporationInventors: Samuel Joseph Nicolosi, William A. Burton, Dara Nanette Lubin

Publication number: 20010037925Abstract: A step-by-step ratchet mechanism has a mount, a hand lever that is carried on the mount and is pivotal about an axis of the hand lever, and a ratchet that is provided with a toothed set wheel and with an output shaft that is rotatable about an axis of the ratchet in the mount. Two catches are provided, they a) are each hinged on the hand lever and are pivotal around an axis of the catch, b) are each provided with a gear cutting that cooperates with the set wheel, c) are provided with a supporting flank that neighbors an abutment of the mount and d) are provided with a first elastic means that resiliently pretensions the two supporting flanks towards the abutment. Each catch is further provided with e) a pin. The gear cutting is designed as a toothed quadrant with several teeth. Two mean position levers are carried on the mount and are each pivotal about an axis of the mean position levers, one mean position lever being assigned to each catch. The mean position levers are provided with a stop flank.Type: ApplicationFiled: May 4, 2001Publication date: November 8, 2001Inventors: Burokhard Becker, Robert Houston
