As the motor is rotated in reverse rotary directions, the connecting portions of the rods that are coupled to the parking brakes are moved in opposite, straight line directions to move the parking brakes between brake disengaged and brake engaged positions.Type: GrantFiled: March 22, 2011Date of Patent: November 5, 2013Assignee: The Toro CompanyInventors: Dale A. Stover, Karl D. Heal, Steven R. Porter

Patent number: 8567570Abstract: A brake assembly for use with a portable generator includes a frame, a shaft, a brake surface, and an actuator. The frame is designed to be attached to the portable generator. The shaft is supported by the frame, and the brake surface is connected to an end of the shaft. The actuator includes a foot pedal, a cam, and a pivot, where the pivot is coupled to both the foot pedal and the cam and provides for rotation of the foot pedal and the cam about a portion of the frame. The cam of the actuator translates the shaft between a released position and a braked position during operation of the brake assembly.Type: GrantFiled: May 14, 2010Date of Patent: October 29, 2013Assignee: Briggs & Stratton CorporationInventors: Richard A. Junk, Ryan S. Jaskowiak, Gregory G. Wesolowski

Patent number: 8522934Abstract: A lockable piston-cylinder unit includes a cylinder having at least one axially facing counterstop; a piston dividing the cylinder into a first working chamber and a second working chamber; a piston rod extending through the first working chamber to a free end outside the cylinder; and a fastening tube having a first end in which the free end of the piston rod is fixed, a second end which receives the cylinder coaxially, and at least one axially facing supporting stop. When the piston rod is extended to maximum extension, the fastening tube is rotatable relative to the cylinder from a release position, wherein the supporting stop is offset from a respective counterstop, to a locking position, wherein the supporting stop faces the counterstop so that the fastening tube cannot move axially relative to the cylinder.Type: GrantFiled: March 19, 2009Date of Patent: September 3, 2013Assignee: Stabilus GmbHInventor: Frank Born

Patent number: 8496092Abstract: A parking brake lever apparatus for a vehicle includes a first latchet member and a second latchet member arranged along the direction of an axis of a rotating shaft of a holder member which rotatably supports a parking brake lever. The first latchet member and the second latchet member are arranged so that respective teeth thereof come into contact with each other at end surfaces facing in the direction of the axis of the rotating shaft when the parking brake lever is in an unlocked position. The first latchet member is moved toward the second latchet member by springs so that the respective teeth of the first latchet member and the second latchet member are engaged with each other when the parking brake lever is in a locked position.Type: GrantFiled: September 1, 2010Date of Patent: July 30, 2013Assignee: Honda Motor Co., Ltd.Inventors: Hiroshi Furuse, Ikuo Hara, Rui Maeda, Chihiro Iida

Patent number: 8469158Abstract: An operating system for a parking brake, in particular of a motor vehicle, includes an operating element which is manually brought from a release position to a brake position for engaging the parking brake and which can be removed from the brake position without disengaging the parking brake. The operating system includes a follower element which is connected to the operating element such that the follower element follows any movement of the operating element. Further, the operating system includes a releasable locking mechanism with a locking element to lock the follower element in the brake position and a separating element which allows to separate the connection between the operating element and the follower element independently from the releasable locking mechanism.Type: GrantFiled: June 13, 2005Date of Patent: June 25, 2013Assignee: Fico Cables, S.A.Inventors: Jaume Prat Terradas, Jordi Vidal Jornet

Patent number: 8424655Abstract: A brake cylinder for pneumatic vehicle brakes includes a spring brake section for parking brake actions and a service brake section for service brake actions combined in one housing. The housing is subdivided by a piston into two compartments, one compartment being used as the pressure compartment for the service brake, and the brake spring of the spring section being arranged in the other compartment on the opposite end of the piston. The brake spring acts upon an additional spring piston, which can be locked and released relative to the piston by a pneumatic locking mechanism. The spring piston is connected to a piston rod directly or via additional elements to actuate the brake. Once the locking mechanism is released, the brake spring displaces the pistons relative each other during a parking brake action. At least one pneumatic valve for controlling the brake cylinder are integrated into the brake cylinder.Type: GrantFiled: September 25, 2009Date of Patent: April 23, 2013Assignee: KNORR-BREMSE Systeme fuer Nutzfahrzeuge GmbHInventor: Johann Iraschko
