-
Patent number: 6761228Abstract: In a preferred embodiment of the invention an extension section of a frame is held down in its locked position by the same mechanism that folds and unfolds the frame extension. When the frame extension is in its locked down position, it bears against a limit stop that precludes further movement in an unfolding direction. An operating link that is pushed and pulled by a hydraulic cylinder to manipulate the frame extension is controlled in such a way by a guide member that the line of action of the link is directed transversely toward a guide surface of the guide when the frame extension is in its unfolded position. Thus, only a small amount of force is required from the hydraulic cylinder at that time to maintain the link in its locked position, since most of the load from the link is born by the guide surface at this time. In a preferred embodiment, the line of action of the link is approximately perpendicular to the guide surface.Type: GrantFiled: October 9, 2002Date of Patent: July 13, 2004Assignee: Morris Industries Ltd.Inventors: David A. Dobson, Cory W. Ochitwa

Patent number: 6761252Abstract: The present invention relates to an electromechanically actuated partially lined disk brake suitable both for realizing driving and parking brake functions. For this purpose, the partially lined disk brake comprises a brake caliper with an electromechanical actuating unit, by means of which the partially lined disk brake can be clamped by way of at least one interposed actuating element. The object of the invention is to achieve a compact design and a parking brake that can be actuated electrically. The brake caliper includes a multi-step reduction gear arranged between the integrated actuating unit and an actuating element. The actuating unit, reduction gear and actuating element are arranged in a recess of the brake caliper that is configured as a housing. According to the invention, the multi-step reduction gear is configured as a non-self-locking device, i.e.Type: GrantFiled: January 11, 2002Date of Patent: July 13, 2004Assignee: Continental Teves AG & Co.

Patent number: 6761253Abstract: A spring applied parking brake assembly for a railway vehicle is provided which automatically activates upon removal of a railway car from the pneumatic braking system of the railway vehicle. The spring applied parking brake assembly comprises a casing which is mounted on or within the braking system, typically alongside the air cylinder. This casing contains a spring member and a piston assembly, both of which are mounted for longitudinal movement within the casing upon the application and/or removal of pneumatic pressure within the casing. The piston assembly includes a piston rod which is associated with the force transfer lever of the braking system such that upon a removal of pneumatic pressure within the casing, longitudinal movement of the piston rod causes this force transfer lever to rotate and apply a force to at least one force transmitting member in the vehicle braking system to initiate a brake application.Type: GrantFiled: February 24, 2000Date of Patent: July 13, 2004Assignee: Westinghouse Air Brake CompanyInventors: Wajih Kanjo, Scott Natschke

Patent number: 6761254Abstract: Brake assembly for cyclists' training device, provided with a support structure (7) on which there is rotatably mounted a shaft (10) having, keyed thereto, a roller (6) rotating in contact with the rear wheel of a bicycle. An end portion (12) of the shaft (10) is provided for this purpose with magnetic elements (13) able to exert a resistive torque and provided with a rotor (17) keyed onto the shaft (10) and carrying, fixed thereon, one or more permanent magnets (18) and a stator (19) mounted on the support structure (7) in the vicinity of the rotor (17). The stator (19) is composed of a disk of ferromagnetic material (20) and a shaped plate (21) of substantially conductive and non-magnetic material fixed to the ferromagnetic disk (20) on the side where the rotor (17) is located.Type: GrantFiled: September 16, 2002Date of Patent: July 13, 2004Assignee: Elite SrlInventor: Gaetano Mercante

Patent number: 6761256Abstract: A clutch arrangement for rapid disengagement of two elements in a transmission system when a chosen torque is exceeded. The first element is a conical shaft end that carries a corresponding sleeve which, in turn, carries externally at its ends two mutually separated ball bearings with a force transmission ring disposed therebetween. The second element, an annular force transmission body, surrounds and is carried by the ball bearings and includes a pressurisable hydraulic chamber which, when pressurised, causes a reduction in the inner surface diameter of the body so that the body is brought into force transmitting engagement with the outer surface of the ring. The sleeve carries a dogging element which is adapted to act on an element carried by the body for depressurising the hydraulic chamber upon relative rotation between the body and the sleeve such that, when the chosen torque is exceeded resulting in the relative rotation, the chamber is depressurised, and the ring and the body pass free from each other.Type: GrantFiled: September 27, 2002Date of Patent: July 13, 2004Assignee: Voith Safeset ABInventor: Curt Falk

Patent number: 6761259Abstract: A moving handrail superior in durability includes a linear belt of which two end portions are connected, forming a loop. This linear belt includes a single-layer or multilayer of thermoplastic elastomer having a C-shape in cross section; metallic and web-shaped metal stretch inhibitors disposed along a longitudinal direction of the thermoplastic elastomer, and base members coupled inside of the thermoplastic elastomer. The thermoplastic elastomer, metal stretch inhibitor, and base member are integrally molded. In the connection portion, a splice junction between the metal stretch inhibitors and a joint where the base members are connected together at both end portions with an auxiliary backing does not overlap in a direction of thickness of the moving handrail. Further, the metal stretch inhibitors that are spliced are enclosed with a thermoplastic elastomer.Type: GrantFiled: August 20, 2003Date of Patent: July 13, 2004Assignees: Mitsubishi Denki Kabushiki Kaisha, Kabushikikaisha TokanInventors: Tsuyoshi Onodera, Muneaki Mukuda, Kohsuke Haraga, Ryuji Otsuka, Yuji Kawamura
