A C-ring is firmly in contact with the plate members and biases them toward the engagement groove.

Abstract: A fastener assembly for attaching a fastener to an opening of a sheet material is disclosed. The sheet material is typically located adjacent to a base structure and the fastener assembly affords radial movement of the fastener relative to the opening of the sheet material. The radial movement allows the fastener to be aligned with a desired location on the base structure, e.g. a threaded aperture—after being attached to the sheet material. In this manner, the fastener assembly provides for the placement of the fastener in difficult to reach and/or see locations until it can be attached to the base structure.

Abstract: A retainer clip is used for retaining a lock plug within a bore of a lock housing. The retainer clip includes a generally arcuate body disposeable about the plug outer surface and having a radial retention surface positionable generally against a housing end surface so as to prevent axial displacement of the plug along the bore. Two projections are each disposed proximal to a separate end of the body, each projection being disposeable within a separate plug opening when the body is disposed on the plug to retain the clip engaged therewith. The clip body has a hinge, a first arm portion extending between the hinge and one free end and a second arm portion extending between the hinge and the other end. The hinge is configured so that the two arm portions are deflectable generally about the hinge to move with respect to each other during installation and removal.

Abstract: An elastic fastening ring that can be mounted in a self-clamping manner on a bearing part should have a simple design, a reliable operation and at the same time the function of an axial spring element. For this purpose, the disclosed fastening ring consists of a washer with a sinuous ring-shaped band whose length may be elastically changed in the circumferential direction over its whole radial width.

Abstract: A coupling comprising a first member defining a socket, a second number such as a tube defining a spigot inserted into an open end of the socket, and a locking device received within an annular gap defined between an inner wall of the socket and an outer wall of the spigot. The locking device comprises circumferentially spaced load-bearing members, each load-bearing member extending within the annular gap from a first end which is relatively close to the open end of the socket and a second end which is relatively remote from the open end of the socket. Each load-bearing member is resiliently biased such that the first end engages the socket and the second end engages the spigot, and each load-bearing member is dimensioned such that it acts substantially as a beam in compression to resist withdrawal of the spigot from the socket.

Abstract: A washer assembly which may be assembled and locked into place without fully removing a bolt or screw is described herein. The assembly is comprised of at least two identical segments, each having a male end and a female end. The segments are fitted together, preferably along a planar axis the male end of one segment fitting into the female end of the second segment; and the male end of a second segment fitting into the female end of the first segment. The male end is comprised of a flattened tongue, preferably circular, having convex nodules on at least one surface of the tongue. The female end is comprised of two flattened essentially parallel leaves forming the opening of a slot. At least one inner surface of this slot has at least one complementary concave depression. When the flattened tongue fits into the slot the convex nodules snap into the complementary concave depressions, locking the segments of the washer assembly together.

Abstract: A bowed external spring retaining ring of the E-shaped type includes flats at the leading and trailing ends of the ring. The flats form leading and trailing edges of the ring which are rounded on a concave side of the ring. The ring is formed by a punch which has an end face comprised of a concave portion and straight portions, the latter forming the flats on the ring.

Abstract: In a quick-action connection for retaining an insertion part in an orifice of a carrier, for example a holding nipple in a body wall, there is, in a peripheral groove of a tenon-shaped extension piece of the insertion part, a retaining ring resiliently flexible in the radial direction, which has its largest diameter in the inserted state of the insertion part. The retaining ring partially projects beyond the periphery of the extension piece and is supported on the carrier by means of one of its end faces. So that the retaining ring is capable of guaranteeing a reliable mutual connection of the two parts, even when bending moments are exerted on the insertion part inserted into the carrier orifice with a clearance fit, its annular shell is closed in the peripheral direction and extends in the form of a meander. As a result of this ring design, the retaining ring can be compressed radially in order to introduce the insertion part into the carrier orifice, and after insertion it automatically springs open again.

Abstract: An attachment and method for axially securing a component on the surface of a shaft or bore by forming an annular groove adjacent the component and inserting a closed retaining ring within the annular groove. The retaining ring has a larger internal diameter than the diameter of the shaft or a smaller external diameter than the diameter of the bore. The retaining ring is pressed into the annular groove and plastically deformed by a tool that contacts the ring at angularly spaced portions of the retaining ring surface until the ring fills the groove without axial clearance or play. The annular groove formed on the shaft or bore has a cross section for receiving a standard commercial retaining ring or circlip. The portions of the retaining ring located between the portions that are deformed by the tool form convex portions that extend radially away from the annular groove and define a space for the insertion of a prying tool.

Abstract: A vial retaining assembly for a level or like object employs a retainer member for securing the vial in a mounting receptacle of the level. The retainer member comprises a first set of generally radially extending ears which frictionally engage the wall which defines the receptacle. A second set of radially extending ears forcefully engages the end of the vial to secure the vial in fixed relationship within the receptacle.

Abstract: A bolt lock, for receiving and locking the end of a bolt having a head portion with a locking shoulder, said lock comprising a housing having internal jaws forming a central aperture, said jaws being expansible to allow the head of the bolt to snap through the opening so the the bolt shoulder latches behind the jaws. The jaws are retained in the housing above an aperture in the body which receives the inserted bolt head and below a bolt aperture in the upper portion of the housing, so that when the bolt is assembled, axial movement thereof causes the edges of the apertures to contact the internal jaws around and in spaced relation to the central aperture thereof. The jaws have upper and lower surfaces which are slightly inclined toward each other in relation to the axis of the central opening from the central aperture to the periphery of the jaws.
