Publication number: 20150013494Abstract: The present invention enables a user to intuitively grasp the occurrence of prescribed phenomena during operation. Provided is a damper that restricts pivot pin (4) rotation associated with operation of an operating section, wherein the friction resistance that impedes the rotation of the pivot pin (4) is changed in a stepped fashion. When the pivot pin (4) rotates in direction ? due to the depression of an accelerator pedal (operating section) (21), a slide cam (62) shifts an edge section (621A) of an inclined cam surface (621) in a direction A away from a rotating cam (61) while staying in contact with a gradual first inclined region (611A) of an inclined cam surface (611) of the rotating cam (61).Type: ApplicationFiled: February 21, 2013Publication date: January 15, 2015Inventors: Hideto Arigaya, Katsutoshi Kumazawa, Kentaro Yamauchi, Daisuke Yoshimoto

Publication number: 20140291079Abstract: A device for preventing and/or stopping rotation of a shaft coupled to a motor, of the type having a first fixed element with respect to this shaft, and a moving element, and means to constrain the moving element to the shaft in such a manner as to rotate integrally with this shaft and at the same time be able to move between a position of friction contact with the fixed element, to allow stopping of the shaft, and a position of disengagement from this fixed element, to allow release of the shaft is disclosed. The device advantageously provides that the means to constrain the moving element to the shaft include a link for movement of the moving element along a direction having a radial component with respect to the shaft.Type: ApplicationFiled: June 29, 2011Publication date: October 2, 2014Applicant: MAX PROP S.R.L.Inventor: Massimiliano Bianchi

Publication number: 20140238785Abstract: A brake for a rod includes a spool-shaped lock having conical opposed open ends communicating with a cylindrical opening. Positioned within the cylindrical opening is an inwardly projecting shoe for engaging the outer cylindrical surface of a rod to be controlled. A pair of conical members are positioned in association with the mating conical ends of the spool and are housed in a cage for holding the components in an assembled position when a rod to be controlled is inserted through the conical members and the spool-shaped locking member. The conical members are biased to a locking position and a control rod is coupled to the spool and actuated by a safety release mechanism to allow the rod to move. In a preferred embodiment, a gas spring with the present locking mechanism is coupled between two telescopic tubes defining one or more adjustable legs for a table or chair.Type: ApplicationFiled: February 22, 2013Publication date: August 28, 2014Applicant: Suspa GmbHInventors: Glen Robert Wilkinson, Kevin Thomas Braat

Patent number: 8794684Abstract: An oilfield elevator is disclosed and has first and second body halves pivotally-coupled at a hinge and moveable between an open position and a closed position to receive and move a tubular segment. Slips are slidably received within corresponding tapered slots in the elevator and are configured to translate vertically within the tapered slots and, at the same time, radially so as to be able to capture a wider range of tubular having varied outside diameters. Tension handles are pivotally-coupled to the first and second body halves and moveable between locked and unlocked positions. Locking the tension handles engages the slips via biasing members, and forces the slips into radial contact with the tubular segment. Unlocking the tension handles releases the biasing members.Type: GrantFiled: April 30, 2012Date of Patent: August 5, 2014Assignee: Frank's International, LLCInventors: Jeremy Richard Angelle, John Erick Stelly, Tyler J.

Publication number: 20140131145Abstract: A linear stopper including a stopper body having an inclined surface with a wedge-like space between the inclined surface and a surface of the guide member with a gap decreasing gradually toward one side of an extending direction of the guide member; rolling elements that are arranged in the wedge-like space so as to be rollable therein; and rolling element pressing means that presses the rolling elements in a direction to bite into the wedge-like space, so that the rolling elements are forced into pressure contact with the surface of the guide member and the inclined surface of the stopper body. A one-way stopper mechanism restricts the relative movement of the stopper body with respect to the guide member toward a side at which the gap in the wedge-like space is large, but allows the relative movement toward a side at which the gap in the wedge-like space is small.Type: ApplicationFiled: November 14, 2013Publication date: May 15, 2014Applicant: TALK SYSTEM CO., LTD.Inventors: Shigeru WAKO, Yoshikazu KOMIYA

Publication number: 20140116813Abstract: A centrifugal brake system for retarding shaft backspin includes a brake drum, a brake hub attachable to the shaft and two or more brake shoes mounted on the hub for braking engagement with the drum. A mechanical linkage transfers the generated braking force from the brake shoes to the hub and permits radial displacement of the brake shoes relative to the hub, upon rotational shifting of the hub relative to the brake shoes between deactivated and activated positions. In the deactivated position of the hub, the brake shoes are maintained in a radially inward, disengaged position. In the activated position, the brake shoes are radially displaceable by centrifugal force from the disengaged position to a radially outward, engaged position, wherein the brake shoes are in braking engagement. The rotational shifting of the hub is achieved through frictional drag between the brake shoes and the brake drum.Type: ApplicationFiled: October 25, 2013Publication date: May 1, 2014Applicant: KUDU INTERNATIONAL INC.Inventors: GARY TICKNER, Robert A.R.
