Abstract: The present invention includes an improved metal fence post for use with a wooden fence. The fence post has a U-shaped center section positioned between two flanges, and each of the flanges includes a plurality of holes extending along an edge. The fence post can be used as a line post, corner post or end post. Preferably, the thickness of the sides of the U-shaped center section is about the same as the thickness of the wooden fence rails so that the fence posts are positioned in-line with the fence rails. Advantageously, the fence posts allow the fence boards to be attached to either or both sides of the rails.

Abstract: A device for use with a hinge in which two rigid elements (104, 105) may be placed in various relative angular positions, wherein the elongate part (109) to be protected and guided consists of a section or tube inserted through two mutually facing channels (111, 110) in respective ones of the rigid elements (104, 105). The device includes a movable member (107) arranged between said rigid elements (104, 105) and at least rotatably movable about a rotational axis of said hinge. The member further includes a hole (108) through which said elongate part (109) may inserted.

Abstract: A connector for securing a constant velocity universal joint having a housing to a coupling member, the housing and coupling member each having an inner surface and an outer surface. The connector includes an annular member having a first end, a second end, and a plurality of openings which extend axially from the first end to define a series of radially expanding panels for receiving the constant velocity universal joint and coupling member. The joint and coupling member each have respective mating surfaces which engage each other. The first end of the annular member engages the outer surface of the coupling member and the second end of the annular member is disposed proximate the outer surface of the housing. The mating surfaces are splined for transmitting torque. At least one wave spring is provided with the connector to accommodate axial deviation.

Abstract: A fold latch assembly is provided for use with a collapsible stroller. The fold latch assembly includes a latch slidably connected to an arm of the collapsible stroller, a housing pivotally attached to the latch and slidably attached to the rear leg of the stroller, and a mount fixedly attached to rear leg of the stroller. The latch operates to releasably secure the collapsible stroller in an operative position and may be released to allow the stroller to be biased into a collapsed position.

Abstract: A guardrail system including a rail and rail connectors is described wherein the rail is formed of several elongated tubes which are integrally molded at the tube sidewalls. The tubes preferably have polygonal cross-sections with sidewalls situated in horizontal and vertical planes, with the vertical sidewalls of the various tubes staggered at different depths within the rail. Connections between rails may be achieved by internal connectors which fit within the tubes of adjacent rails, and/or by use of external connectors which receive the ends of adjacent rails. Such internal and external connectors may also be used to reinforce damaged rails to restore their performance characteristics.

Abstract: A rotary flexure is designed to exhibit very high radial and axial stiffness and to exhibit virtually no movement in its center of rotation. The flexure, which is formed from a single billet of material, includes an outer ring from which three thin flexure blades extend. The flexure blades extend toward the centerpoint of the rotary flexure, where they join to form a centerpiece. Three lobes also join at the centerpiece, one between each pair of flexure blades. The lobes extend toward the outer ring, and are free to rotate about the pivot axis with respect to the outer ring and the flexure blades. During rotation, the pivot axis exhibits virtually no movement.

Abstract: A pivotal device for connected two parts of a foldable bicycle includes two boards each are connected to a part of the bicycle and are pivotally connected with each other. A clutch device is connected between the two boards and includes two pins extending through the two side plates of each of the two boards. Each of the pins are movable to disengage from one of the two boards to allow the two boards to be pivoted away from each other. A secure device is connected to the clutch device so as to secure the pins of the clutch device in position such that the two boards are not pivoted away from each other.

Abstract: A switching cabinet has a frame made of stays and with open sides that may be at least partially closed by wall elements that can be secured to the stays of the framework. In order to secure the wall elements to the framework in an manner invisible from the outside, projecting hook elements are fixed on the inner side of the wall elements, matching hook elements can be hooked into the projecting hook elements and the matching hook element can be mounted on the framework stays so that the hook elements may be hooked onto them.

Abstract: An outer member and an inner member are drivingly connected at a toothed interface. The members are restrained from axial separation by a retaining ring. The retaining ring is engaged in a groove formed in the inner member and has a pair of tabs which extend radially outward through slots in the inner member. The tabs abut an end face on the outer member thereby preventing relative axial displacement of the inner and outer members.

Abstract: In a cable joint structure, a first casing has a first rail member. A first end portion has a lug portion directed opposite to the first rail, and connected to one end of a first cable so that the first end portion moves along the first rail member. A second casing has a second rail member. A second end portion has a recess portion into which the lug portion interfits from a direction opposite to the second rail member, and connected to one end of a second cable so that the second end portion moves along the second rail member. A lock member is provided to unite the first casing to the second casing with the first rail member located to face the second rail member.

Abstract: A holding device hold a first member in position relative to a second member on a clamping pin. Two racks respectively one connected to the first and second members and adapted to interengage in a locked position. A return spring separates the racks in an unlocked position. An additional spring co-operates with a bracket. The racks, return spring and additional spring are mounted on the clamping pin. The additional spring bears against the bracket and operates on the mobile rack to assure complete interpenetration of the mobile rack and the fixed rack. The main application of the device is to automobile vehicle steering columns.
