Abstract: A formed body of Cu—Al—Mn-based shape-memory alloy may include a screw portion, wherein the screw portion is a form-rolled portion. A method for producing a formed body of Cu—Al—Mn-based shape-memory alloy may involve forming a screw portion having superelasticity by plastically working at least a portion of a material for the formed body with form-rolling in a state that a crystal structure is an A2-type structure and then, subjecting heat-treatment so as to convert the A2-type crystal structure into an L21-type crystal structure. The screw portion can be formed with good working property, and has excellent fatigue resistance and breaking resistance.

Abstract: The clip includes a head part, a shaft part, a pin having first and second engaged parts at the shaft part, and a grommet having a flange part with an insertion hole, a leg part, and an engaging part engaging with/disengaging from the engaged part. The pin has the engaging part near the inner periphery of the insertion hole of the flange part. The pin has guide grooves between the first and second engaged parts to guide the movement of the pin while movably engaging the engaging part. Switching between a temporary fixing state and a permanent fixing state is conducted through movement of the shaft part associated with guiding by the guide grooves. When the pin in the permanent fixing state is rotated and moved in the pull-up direction associated with guiding by the guide grooves, engagement between the engaging part and the second engaged part is released.

Abstract: The present invention relates to an anchor bolt and more specifically pertains to a post-installed anchor that is securely anchored to, for example, an existing concrete floor. The post-installed anchor has a sleeve fit on a bolt body and a fixation member arranged on an edge of the bolt body and screwed to a threaded end of the bolt body. The fixation member has an internal threaded end and an expansion end. The expansion end is divided into four expansion pieces by slits. The expansion pieces are arranged to face a head of the bolt body and are slightly widened toward the head of the bolt body. One end of the sleeve forms a tapered face. After insertion of the post-installed anchor into a pilot hole (installation hole) bored in the concrete floor, as the bolt body rotates, the fixation member screwed to the bolt body moves toward the sleeve. This movement causes the expansion end of the fixation member to ride on the tapered face of the sleeve and to be pressed open and extended outward.

Abstract: The invention relates to an expansible fixing plug having a fixing plug sleeve and an expander screw (10). The invention proposes to align the rear (in the direction of screwing-in) flank (20) of a screw thread (18) of the expander screw (10) at a shallow angle of about 9° relative to the axial direction of the expander screw (10) and to construct the screw thread (18) with a large thread pitch. In the event of the expander screw (10) being subjected to stress in the pull-out direction, the rear flank (20) acts in the manner of expander cones arranged one behind the other axially and expands the fixing plug sleeve. The expansible fixing plug exhibits subsequent expansion behaviour in the event of the drilled hole's becoming wider.

Preferably the sleeve is twisted slightly in a spiral-like manner so that an end of the sleeve serves as one of the coacting structures which engages an adjacent ridged or other not smooth surface of the nut serving as the other coacting structure.

Abstract: An expansion dowel consists of an axially extending dowel body with a spreading member at its leading end and an expansion member extending around the dowel body rearwardly of the spreading member. A helically arranged control cam surface is formed on the expansion member and faces toward the trailing end of the dowel body. A stop is formed on and extends outwardly from the dowel body and contacts the control cam surface. When the dowel body is turned around its axis relative to the expansion member, the stop rides on the control cam surface and causes the spreading member to expand the expansion member radially outwardly.
