Abstract: A wall anchor having a first inclined plane secured to a second inclined plane by a connector. The connector is resilient to allow the inclined planes to move relative to one another. The inclined planes are oriented opposite one another, in a manner which increases their combined height as the inclined planes slide in a first direction relative to one another, and which decreases their combined height as the inclined planes slide in a second direction relative to one another. A retainer is secured to the first inclined plane and is used to insert the inclined planes into a hole in a wall. After the inclined planes have been inserted, the retainer is withdrawn slightly, which causes the inclined planes to slide relative to one another and increase their combined height to wedge the inclined planes against an interior surface of the hole. In this manner, a retainer may be securely and manually anchored to a wall.

Abstract: The new fastener has a shank which is resiliently compressible along an axis perpendicular to the shank push-in axis and has teeth protruding from the shank along the axis of resilient compressibility. The teeth are inclined in the push-in direction and in the pull-out direction. When the shank is pushed into an existing screw hole, then inclines of teeth just past the far side of the screw hole are increased to resist motion in the pull-out direction so that the shank is secured in the screw hole and so that the fastener can be pulled-out without damage. The shank can be integrally part of a first structure being fastened to a second structure.

Abstract: The object of the present invention is to provide a one-part clip, in low manufacturing cost, exhibiting the excellent function of the two-piece clip and having enough mounting strength without degrading easy repetitive detachability. Hinges 50 that connect a bar portion 30 and a leg portion 40 move so as to widen each elastic portion 43 of the leg portion 40 within the inside of the mounting hole al of the body panel A when the bar portion 30 is moved axially into the inside of the leg portion 40 by forcing the head portion 20 of the clip 10 along axis of the bar portion 30. The engaging portion formed near the end of the bar portion 30 is forced into the engaging hole 42 formed at the top end portion 41 of the leg portion 40 when the bar portion moves axially. If the head portion 20 is pulled strongly to move the bar portion 30 in opposite direction, it can be removed from the body panel A without incurring any damages.

Abstract: A resilient snap fitting retainer provides a desired retention force despite tolerance variations. A pair of parallel resilient legs extends from a base. The legs are separated by a gap. A deformable rib is provided on at least one of the legs to partially crush when the legs are compressed with sufficient force. The partial crushing compensates for tolerance variations in the size of an opening into which the retainer is inserted or in the size of the retainer itself. The legs are elongated and terminate in wedge shaped feet at their distal end. The feet form a generally arrowhead-like shape for insertion into an opening. The structure of the feet and legs enables the legs to deflect toward each other (i.e., buckle) after the interior surfaces of the legs have made contact at their distal ends as the feet are pushed through the opening.

Abstract: A uni-directional slack adjuster is incorporated into a hold-down tension rod or strap, such as a hold-down anchor bolt for bolting a shear wall on one floor to a shear wall or foundation wall below, when a wood floor joist assembly is in between. The slack adjuster eliminates bolt slack so that in the event of an earthquake or hurricane, the sill plate is positively anchored with no vertical bolt play, eliminating much of the cosmetic damage that is often done to the wallboard and other finished surfaces due to distortion of the wallboard framing as the sill rises abruptly until it reaches the end of travel on the hold-down bolts. The slack adjuster comprises a link in the tensioner and non-reversibly either expands or contracts axially depending on the particular embodiment.

Abstract: The present invention anti-rotational fastener for an automotive vehicle comprises a cap portion suitable for attachment to an electrical apparatus and a barbed shaft. The shaft has a pair of broad sides and a pair of thin sides, all of which extend perpendicularly downward from the cap portion for attachment to an automotive vehicle body panel. This difference in shaft side dimensions corresponds to an elongated slot cut within the vehicle body panel, thereby preventing rotation of the fastener and, in turn, the electrical apparatus. Furthermore, an upper portion of the shaft broad sides has a pair of wings oppositely extending outward therefrom in order to mechanically stabilize the fastener against rotational movements in vertical planes which would otherwise tend to loosen the fastener. In an alternative embodiment, the anti-rotational fastener of the present invention can be used to retain and prevent rotation of a portion of a wire harness.

Abstract: Fixing devices for connecting components, particularly prefabricated concrete members and tubbing stones, consist of pluglike anchors adapted to be forced with elastic deformation into anchor holes, which are formed in the components and are open to the joint between the components. As a result, the anchors are frictionally held in and/or positively locked in the anchor holes. The anchors are substantially stiff and have a peripheral surface which at least in portions intended for a retaining engagement with the inside surface of the anchor hole is designed to be elastically deformable at least in an approximately radial direction. The surface consists at least in these portions of a plastic material which has entropy elasticity.

Abstract: A plurality of anchoring members are threaded onto the shaft of the fastener. These anchoring members include an annular body and a spacer. The anchoring members are held between an abutment of the shaft and a locking section thereof fixed against an axial displacement thereon. The anchoring members are present as structural members which are separate from the shaft and are merely threaded onto the shaft. It is accordingly possible to use a large number of variously designed anchoring members together with only one shape of the shaft, which reduces considerably the costs of the production and increases the universality of the fastener. Specifically the shaft and the anchoring members may be made of a metal such that the fastener can display in comparison with plastic fasteners a much higher rigidity.

The fastener is frangible for fracture upon the application of a tensioning force thereto permitting the first and second members to which the fastener is engaged to be displaced relative to one another. The fastener, once fractured, is retained in the corresponding first and second members to which it was originally attached to prevent the generation of loose pieces. An installation tool is also provided for installing the fastener into the first and second members. The fastener includes a shank which fractures into a first and a second segment. A frangible portion of the fastener is spaced along the shank between the first and second segments and defines such segments for providing a predetermined fracture point. Non-planar engaging portions on the first and second segments retain the fastener in the corresponding first and second members once engaged therewith even after fracture of the fastener.

Abstract: A washer is positioned beneath a superimposed assembly of two or more flat thin objects (e.g. resin sheets) which is horizontally supported. A hollow joining pin is fitted about a metal pin supported vertically and coaxially with the washer. The joining pin has a head, a shank and a tapered end portion which is severable from the shank. The metal pin has a pointed end about which the tapered end portion of the joining pin is positioned. The metal pin is vertically movable with the joining pin, or independently of it. The metal pin and the joining pin are moved down to drive its pointed end and its tapered end portion, respectively, into the assembly to make a hole therein and force the shank through the hole until the shank is engaged with the washer, whereby the objects are secured together between the head of the joining pin and the washer. The metal pin is moved down through the joining pin to sever its tapered end portion from its shank. The objects, washer, and joining pin are all of the same material.
