Patent number: 7549518Abstract: A brake for retaining a mobile carriage on which apparatus such as storage facilities are located. The brake includes a pivot member with a release end and a locking end and with a claw at the locking end. The claw engages a slotted member when the locking end is depressed. The opposite end of the pivot member from the locking end is the release end. Adjacent the release end is a slot which rides on a stoop pin to prevent the release end from being depressed below the horizontal.Type: GrantFiled: March 16, 2007Date of Patent: June 23, 2009Inventor: Lance Pennington

Patent number: 7537093Abstract: A brake device for a pushcart includes a rotary lever rotatable on a base between first and second positions and biased to the first position. A cam member is rotatable within the rotary lever, and has a convex portion and a concave portion. A braking pin is disposed movably on the base, and is biased to contact the cam member. When the rotary lever is rotated from the first position to the second position, the cam member rotates so as to move an end of the braking pin from one of the concave portion and the convex portion onto the other one of the concave portion and the convex portion, thereby switching the braking pin between a braking position and a release position.Type: GrantFiled: September 8, 2005Date of Patent: May 26, 2009Assignee: Wonderland Nurserygoods Co., Ltd.Inventor: Shun-Min Chen

Patent number: 7510057Abstract: A parking brake for a commercial vehicle equipped with an air-operated service brake is configured in such a way that the actuating energy for the brake is reduced in comparison to a configuration with a spring brake cylinder, while the installation space in the wheel area is minimized. Primary functional parts of the parking brake include an inner race and an outer race, which delimit an annular gap. Displaceable tapered-roller bearings are located in the annular gap. To adopt a release position in opposition to the action of a compression spring, the tapered roller bearings are disengaged from the conical surfaces of the inner race and the outer race.Type: GrantFiled: March 15, 2007Date of Patent: March 31, 2009Assignee: Knorr-Bremse Systeme Fuer Nutzfahrzeuge GmbHInventors: Wolfgang Kiener, Stephan Lange, Johann Baumgartner, Eduard Gerum, Michael Herges, Dirk Ganzhorn, Bence Csàk, Nicolas Savagner, Uwe Neumann, Matthias Gradl, Matthias Schaefer

Patent number: 7476172Abstract: A brake mechanism for a motor assembly including a motor and a reduction gear assembly driving an output shaft or axle is disclosed. A brake rotor is driven by the motor shaft and a brake puck is operatively engageable with the brake rotor for moving the brake rotor toward a braking surface. A brake cam shaft is rotatably supported about an axis perpendicular to the axis of the output shaft and engages the brake puck so that rotation of the brake cam shaft about its axis forces the brake puck to move the brake rotor toward the braking surface.Type: GrantFiled: March 10, 2008Date of Patent: January 13, 2009Assignee: Hydro-Gear Limited PartnershipInventors: Thomas J. Langenfeld, Shane A. Deters

Patent number: 7448476Abstract: A cart having a frame for conveying cargo. The cart includes at least one brake assembly mounted within the frame of the cart. The brake assembly is configured to provide braking by engaging and disengaging a rear wheel axle. The cart further includes a control mechanism configured to selectively engage and disengage the brake assembly by rotation of a cart handle. In addition, the cart includes a brake release device configured to disengage the brake assembly when carts are nested.Type: GrantFiled: November 6, 2003Date of Patent: November 11, 2008Assignee: Smart Carte, Inc.Inventor: Dan L. Otterson

Patent number: 7428951Abstract: In a braking device for an elevator, a sheave around which main ropes for suspending a car and a counterweight are looped is provided with a pressing device. A braking disc provided with a plurality of engaging portions is pressed against the sheave by the pressing device. An engaging device has a movable portion that can be displaced between an engagement position corresponding to engagement with the engaging portions and a release position corresponding to release from the engaging portions. The braking disc can rotate together with the sheave when the movable portion is at the release position. The braking disc is stopped to brake rotation of the sheave when the movable portion is at the engagement position.Type: GrantFiled: August 19, 2004Date of Patent: September 30, 2008Assignee: Mitsubishi Denki Kabushiki KaishaInventor: Kazumasa Ito

Patent number: 7410038Abstract: A locking unit for the locking of the movement of a piston. An electromagnet is provided the armature, respectively the armature bar, of which acts on an operating element. The operating element co-operates with a catching element in such a way that the catching element blocks in a locking position the movement of the piston, respectively the catching element unlocks in an unlocking position the movement of the piston. Catching element and operating element co-operate surface-to-surface.Type: GrantFiled: October 8, 2003Date of Patent: August 12, 2008Assignee: SVM Schultz Verwaltungs-GmbH & Co.

Patent number: 7407233Abstract: A parking brake system pneumatically actuates an air cylinder to mechanically lock a wheel brake in an applied position in response to a parking demand request. The parking brake system includes a dual hand control that has an electronic control element and a pneumatic control element. The electronic control element communicates with an electronic braking system control unit and the pneumatic control element communicates with a parking brake air reservoir. When the dual hand control is moved to a park position, the electronic control element generates an electronic control signal that applies a parking brake force to the wheel brake. The pneumatic control element generates an air signal that is sent to the air cylinder. The air cylinder includes an extendable shaft that supports a lock member. The air signal moves the lock member into engagement with a brake operating member to lock the wheel brake in the applied condition.Type: GrantFiled: November 4, 2003Date of Patent: August 5, 2008Assignee: ArvinMeritor Technology, LLCInventors: Denis John McCann, Dennis A.

Patent number: 7395902Abstract: A braking system designed to be an integral part of a shopping cart. The braking system consists of a hand-operated brake that is gravity actuated and normally engaged. The user disengages the braking system to move the shopping cart, preferably by pushing a primary handle of the cart. The braking system is also disengaged when the shopping cart is nested with other shopping carts to allow multiple carts to be moved without the brakes being engaged. The mechanical link from the handle to the brake is enclosed within the frame to reduce potential damage to the mechanism. The mechanical link consists of a hand-activated handle that is pushed down to disengage the brake, and when the handle is not depressed, the handle raises by gravity and applies the brake.Type: GrantFiled: February 15, 2005Date of Patent: July 8, 2008Inventors: Paul D'Arca, Monty Hutchison

Patent number: 7370734Abstract: A brake handle assembly for actuating a brake of a wheeled walker of the type having a handle bar member slidably received for telescopic movement within the upper end of a leg member, a wheel rotatably mounted at the lower end of said leg member, a brake mounted at the lower end said leg member, and an elongated brake rod disposed within said handle bar and leg member for moving said brake into and out of braking engagement with said wheel. The brake handle assembly provides a linear pull non-cable brake actuation and is manually operable between a neutral position, a raised brake actuating position and a depressed brake locking position.Type: GrantFiled: October 23, 2003Date of Patent: May 13, 2008Assignee: Random Products TrustInventor: Bjarki Hallgrimsson
