Abstract: A variable grip blind rivet has a rivet body with a first shank adapted to be inserted into a hole in a workpiece and having an axial bore, and a flange at a first end of the first shank for abutting the workpiece when the first shank is inserted into the hole in the workpiece. A mandrel has a head, for engaging a second end of the first shank, and a second shank adapted to extend through the axial bore. The head has an abutment portion for abutting the first end of the first shank. At least one protrusion adjacent the abutment portion defines a recess for receiving the first end of the first shank during setting of the rivet.

Abstract: A bolt (10) for securing timber to any other material, comprises: a bolt head (101) with a series of spiked teeth (102) on its underside; a cylindrical bolt rod (103) extending from the bolt head (101) is threaded and split into two rods (105a,b) at its free end, so as to define a slot (106) therebetween. In use a user drills a hole through pieces of timber to be secured together, and hammers the bolt through the hole. The spiked teeth on the bolt head lock into the timber, securing the bolt at one end. At the free, split end of the bolt rod, a washer and nut are tightened onto the bolt. A cold chisel is hammered into the slot between the split ends of the rod, bending the ends outwards and thus preventing the nut from loosening.

Abstract: A fastener is fixed to a body panel by inserting a second portion of a clip and the body panel between a flange-shaped head and deformed bulge created by crimping a blind rivet inserted into a mounting hole in the body panel. Afterwards, when a fender panel is inserted between a first portion and the second portion of the clip, pressure is applied to the inserted fender panel from above and below by ribs and on the first and second portions, thereby clamping the fender panel between the first and second portions, and fixing the fastener to the fender panel. The fastener is positioned inside an anti-rotation depression in the body panel.

Abstract: An injection molded part accommodates a threaded fastener and includes a metal insert. The insert defines a longitudinal axis and has an end face and an outer peripheral surface. A cutout extends from the end face and through the insert to permit the threaded fastener to extend therethrough. A plastic body surrounds the outer peripheral surface and has a threaded fastener contact face. The threaded fastener contact face of the plastic, body is recessed at a recessed distance below the end face of the insert which has a spring constant with respect to the longitudinal axis. The recessed distance and the spring constant are selected to deform the insert in response to a stress force applied to the end face thereof by the threaded fastener to cause a pregiven component of the stress force to be introduced into the threaded fastener contact face of the plastic body.

Abstract: A window balance assembly comprising an improved locking carrier mechanism is disclosed. The locking mechanism is actuated when the window sash is tilted. Cam surfaces on the receiver of the mechanism engage cam followers in the clamshell-type housing of the carrier forcing them apart outwardly to lock the carrier in the jamb channel of a window assembly and prevent movement of the carrier in the channel. The receiver incorporates two cams that engage two cam follower surfaces in the housing to improve the distribution of the locking forces of the carrier in the jamb channel. A dual-locking carrier expands in both the axial and lateral directions to contact both front and back surfaces and opposing side surfaces of the jamb channel.

Abstract: A fastening member includes a bolt and a nut for attaching a compressor to a vehicle body. A non-circular relative rotation prevention portion is formed below a head portion of the bolt. A washer is non-rotatably press fitted around the relative rotation prevention portion. Before the attachment, the head portion and the washer are temporarily fixed with a space generated therebetween. An elastic body, which is attached to the compressor, is disposed between the washer and the nut. A cylindrical member is provided at an inner circumference of the elastic body. As a result, when the nut is screwed, an axial force of the nut is transmitted to the washer via the cylindrical member, and the space between the washer and the head portion is reduced, completing the attachment.

Abstract: The invention relates to a dowel that is composed of a strand arrangement comprising at least one first strand (12) which extends along a longitudinal axis (L) and at least one second strand (14) which extends at an angle (Y) to the at least one first strand (12) and intersects said at least one first strand (12) at intersection points. The at least one first strand (12) and/or the at least one second strand (14) is/are wound around the longitudinal axis (L) at a certain distance (171, 172) while the at least one first strand (12) is connected to the at least one second strand (14) at the intersection points. The strand arrangement is embodied such and/or is made of such a material that the strand arrangement can be expanded at an angle to the longitudinal axis (L). Such a dowel has the particular advantage of evenly distributing the pressure which acts upon the wall surface (102) of a bore. A single-size dowel can be used for several screw diameters.

Abstract: An anchor assembly (A) for hollow walls comprises an anchor body (400) and a toggle member (231) that is displaceable between a first position wherein the toggle member (231) is substantially aligned with the anchor body (400) such that the anchor assembly (A) can be inserted in the wall (W) via a cutting distal end (325) of the toggle member (231), and a second position wherein the toggle member (231) extends behind the wall (W) at an angle relative to the anchor body (400) which extends through the wall (W). The toggle member (231) is held captive in the first position but is released and then rotated to the second position by a fastener (218) introduced in the anchor body (400). The fastener (218) threadably engages the toggle member (231) thereby drawing the toggle member (231) against a hidden side of the wall (W).

Abstract: Snap fastener for fastening a first thin wall to a second thin wall, having a base part to be arranged in a through-opening of the first thin wall. A head part extends away from the base part. The head part presents a guide for two holding elements which are pressed by a spring so that they project out over the end of the guide. The head part includes a housing with fastening projections, and can be snapped into the through-opening so that it grips only one thin wall. Unlocking devices, via which the holding elements can be pulled back into the housing from the front, are provided in the housing. The holding elements are formed by the ends of a two-armed lever which is held on a shaft in the housing so as to be rotatable at an angle of approximately 45 to 90 degrees against spring force.
