Abstract:
A safety retainer for preventing disengagement of a shackle bolt from a U-shaped shackle. The retainer includes a collar member and a pin member. The tubular collar member surrounds the head of the shackle bolt and is provided with a pair of holes through its walls, coaxially alignable with an aperture in the shackle bolt head, and a notch cut out of the wall of one end thereof for engagement with one arm of the shackle. The pin member is insertable through the pair of collar member holes and the shackle bolt aperture to prevent rotation and disengagement of the shackle bolt from the shackle.
Abstract:
A wheel suspending device for a vehicle has a plurality of leaf springs disposed inside of a rim of the wheel. Each of the leaf springs is a chord member, two extremities of which are supported by the rim member, and a central portion of which is supported by an axle. The axle is inserted in a sleeve, which is fixed to the axle by a nut screwed on an end portion of the axle. A protrusion formed at a center of an inner surface of a cap linked with the nut is inserted in a hole formed in an end surface of the axle.
Abstract:
An anchor assembly for retaining an elongated fastener member within an opening defined by a wall portion of finite thickness and having at least one concealed side. The assembly has at least two elongated leg members of flexible material positioned in parallel relation to each other, with means connecting a pair of adjacent end portions of the leg members together. A generally elongated anchor member is positioned transversely of the leg members and attached to the opposite end portions thereof, the anchor member defining an opening generally medial of the leg members and capable of receiving an elongated fastener member for attachment therewith when the fastener member is positioned between the leg members. Means to connect an end portion of each leg member to the anchor member is provided for each leg member and the leg members and the anchor member connecting means including resilient means associated therewith to bias the anchor member toward its transverse position relative to the leg members against forces tending to rotate the anchor member toward a generally parallel orientation with the leg members, and control of the orientation and position of the anchor member behind the concealed surface of the wall is thereby facilitated by the application of forces either directly or indirectly to the leg members.
Abstract:
A threaded fastener with a central portion separating wider flanges with straight polygonal sides and straight normal flange faces embedded in a plastic. One flange face is flush with the surface of the embedding body to provide a load bearing surface preventing compression of the body.
Abstract:
The system includes a flexible button top which has a sleeve appurtenance which is force-fitted over an externally helically grooved stud assembly having an integral self-adhesive back mounting plate. The button top is flexible enough so that it can be applied to, and removed from the stud assembly without the use of a tool, yet it is hard enough so that the stud will not perforate the flexible button top when impacted. The adhesive-backed stud assembly includes a helically threaded metallic screw perpendicularly attached to a metallic circular disc with a plastic foam backing impregnated with adhesive. The adhesive backing is covered by a release film prior to use. The adhesive-backed stud assembly can be applied without the use of a tool.
Abstract:
A receptacle adapted to be mounted on a member to be fastened and to receive a stud engaged with another member so as to fasten the two members together. The receptacle includes an elongated hollow body portion open at both ends and a flange extending laterally from one end of the body for mounting the receptacle to one member. The body has weakened zones and is surrounded by a compression spring tending to compress the body with the assistance of the weakened zones. A protective cap surrounds at least a substantial portion of the body and is interengaged with the body in position to capture debris displaced from the receptacle or a stud interengaged therewith when two members are fastened together.
Abstract:
The present invention relates generally to nut-type fasteners for application to an apertured panel and more particularly to nut-type fasteners which may be adhesively attached to one side of an apertured panel to facilitate subsequent application of a fastener shank thereto. An embodiment of the invention disclosed herein includes an integral nut-body having a first section adapted to be telescopically inserted within a complementary aperture in a panel. Radiating from the base of said section is a second section of greater diameter providing a panel clamping surface. A sealing type adhesive associated with said clamping surface serves to adhere the nut body to the panel surface upon telescopic association of the first section with a complementary panel aperture whereby to position an axial aperture in the body for receiving a fastener shank, as for example the threaded shank of the screw member.
Abstract:
This invention relates to a fastening device which has a plate, a layer of hot melted adhesive adhered to one side of the plate and a mechanical fastening means protruding from the other side of the plate, and to an apparatus for applying the fastening device. The apparatus has an electrically heated element having an aperture therein shaped so that the mechanical fastening means can be passed through the heating element, control means for turning the heating element on and off, and gripping means adapted to clamp onto a portion of the mechanical fastening means which has been inserted through the heating element. The gripping means, which can be selectively moved between non-clamping and clamping positions, is adapted to hold the fastening device so that the side of the plate not covered with adhesive is in direct face-to-face thermal contact with the heating element.
Abstract:
A threaded insert is affixed within a sandwich panel with a hardenable liquid adhesive which is forced into intimate contact with the body of the insert by helical ribs on the body which move the liquid adhesive during insertion of the insert into the panel and are engaged by the adhesive to anchor the insert upon hardening of the adhesive. The body is a composite construction including a metallic threaded member surrounded by a sleeve of molded plastic which carries the helical ribs.
