Abstract: A hitch pin assembly includes a hitch pin, housing and shoulder bushing. The housing removably connects to the bushing when the bushing is seated in the aperture of a receiver tube. When the housing is so connected a plunger of the housing extends through the bushing and projects into the receiver tube. When the shank is inserted into the receiver tube the plunger tip catches the aperture of the shank, holding the shank in a position in which the pin-receiving apertures on the receiver tube and shank are aligned. The hitch pin is then inserted from one side of the receiver tube and into the bushing. A plunger in the housing translates along a projection in a track of the plunger to reveal the projection to the hitch pin tip and place it into position for engagement with the inserted hitch pin. The engagement holds the shank and eliminates rattling.

Abstract: A claw of a clip includes a slit, an elastic piece, a hinge and a protrusion. The slit includes a pair of opposed vertical grooves parallel to an inserting direction of a leg, a horizontal groove communicating rear ends of both the vertical grooves in the inserting direction of the leg with each other, and a pair of bent grooves line-symmetrically bent closer to each other from front ends of both the vertical grooves in the inserting direction of the leg.

Abstract: A self-locking fastener includes a head, and a solid shaft extending from the head. The shaft includes a threaded portion away from the head. A slot is defined in the threaded portion along the axis of the threaded portion to divide the threaded portion into two parts.

Abstract: A fastener for a heat-radiator on a chip is disclosed. The fastener has a leg. A cone-shaped foot of which a maximum diameter is larger than that of the leg is formed at a first end of the leg. A head is formed at a second end of the leg. Two bow arms are oppositely formed at two sides of the leg each with a first end fixed on a bottom face of the head. A ring is formed on second ends of the bow arms with an opening for the rod to extend therethrough.

Abstract: A toggle fastener which eliminates the need for time-consuming manipulation of a fastener nut comprises a bolt with a head and a stop collar adjacent the bolt head, a wing toggle threaded onto the free end of the bolt, and a spring which extends from the stop collar to a washer. The washer may be flat or a self-centering conically shaped washer. The invention permits the toggle and toggle fastener to be inserted into an aperture in a panel and to then be automatically secured to the wall with an effective firestop provided by the effect of the spring urging the washer into firm contact with the panel.

Abstract: The invention is to a flexible connector for attaching license plates to a vehicle, where the license plate is subject to being hit or moved over objects that would damage the license plate. The connection incudes a spring and plunger in a main body. The plunger has a flexible arm formed thereon which has a key end that connects to a knob. The flexible arm extends through holes in the license plate and a mounting frame and holds the license plate secured to the frame by the knob attached to the key on the flexible arm. When the license plate is hit or moved, the plunger will compress the spring allowing the flexible arm to extend out of the body and flex sufficiently to allow the license plate to move with the force striking it.

Abstract: A twist type locking pin formed from a single piece of wirelike stock having a U-shaped bend forming two sides, one side being bent to form an arcuate loop which terminates short of the other side and is bent at an angle to cross over the other side, the other side being bent to form an arcuate loop which lies in a plane perpendicular to the plane of the first arcuate loop, the end of the second arcuate loop overlying the one side, the second arcuate loop forming a bearing surface at the end of the other side, the second loop forcing the other side outwardly from the one side on insertion of the one side into a post, the other side producing a bias force which rotates the one side through 90.degree. when the end of the other side clears the post to pivot the locking pin to a locking position.

Abstract: A removable step, carried by a highway transport vehicle laterally adjacent the threshold of a side door defined in a cargo container body, aids worker access through the door. The step provides fastening legs releasably maintained in spaced fastening brackets carried by the vehicle frame. The fastening legs are inserted in the upper portions of the fastening brackets in a use mode and in the lower portions of the fastening brackets, with the step extending inwardly, in a storage mode. A releasable fastening pin extends between each fastening leg and associated fastening bracket for positional maintenance of the step in either fastening or storage mode. The step surface is of a non-skid expanded metal type.

Abstract: A method of wall construction using a compressive fastener for log building construction which acts to continuously maintain pressure between individual logs in a building wall which includes a plurality of logs in stacked configuration. Logs are joined by boring a row of bores in the top log and counterboring each bore as a receptacle for the head of the fastener and a concentric spring assembly, the bores being larger than the shank of the fastener as well as the spring assembly to allow the fasteners to freely vertically expand and contract. Once the bored log is stacked and aligned on the log immediately below it, the fasteners are inserted into the boreholes and driven or tightened until the spring assembly is partially compressed and the fastener heads are below the upper surface of the upper log. The compressive fasteners pull the logs together to overcome long-term shrinkage and the continuous expanding and contracting caused by climatic changes.

Abstract: Apparatus is provided for temporarily supporting objects such as toothbrushes. The apparatus includes an anchor part which may be affixed to a supporting structure such as a wall. A detachable section is detachably coupled to the anchor part and is in the form of a bracket including two spaced arms between which extend a pair of spaced parallel rods on which are supported a plurality of clamps having a clothespin-like configuration. The clamps are spaced from one another by sleeves and are provided with elongated openings through which the aforegoing rods extend. These clamps are held by the rods in rectilinear alignment and are color coded in order to be identified with specific objects which are engaged therein.
