Abstract: A releasable mounting system includes a deformable bracket for holding an article. The bracket is formed with a recess which deforms with the bracket. A second element which is fixed to a support is also deformable and includes a plurality of tangs the inner surfaces of which define a central opening and the outer surfaces of which abut the inner walls of the recess. A wedge located in the central opening and secured to the bracket wedges the tangs against the recess walls. Upon distortion of the bracket, the recess distorts permitting at least one of the tangs to disengage from the recess, the central opening to enlarge, and the wedge to pass through the opening, thereby disengaging the article from the support.

Abstract: A clamping device for securing a workpiece such as an electronic package to a support such as a heat sink. A curved slot is machined around a central opening in the body of a configurated flat metal clamp having an extending lip which contacts the edge of the workpiece. The central opening in the clamp body receives a hold down screw member which threadably engages the support. When the hold down screw is fully tightened against the support with the extending lip over the workpiece, the known clamping force predetermined by the thickness and configuration of the clamp body is applied. The need for a torque wrench and specific fastener torque values to prevent possible distortion of the surface of the heat sink is eliminated.

Abstract: A recess-type, screw-receiving fastener is formed directly into a thermoplastic sheet, preferably during the same operation which forms the plastic sheet into a useful configuration, such as a refrigerator inner liner. The fastener, when viewed from the rear side, resembles a plurality of "pinches" forming gusset-like folds. From the front side, it comprises a central recess in communication with side recesses formed by the interiors of the gusset-like folds. The central recess is adapted for receiving a male fastener such as a screw and the gusset-like folds distribute the load into a sufficient surrounding area of the plastic sheet.

Abstract: A mechanically locking fastener has external threads for installation in the threaded bore of a workpiece. A lock ring has internal radial serrations locked in serrations of the fastener proper, and external radial teeth of a form for gripping the wall of the workpiece bore when turning moments tend to loosen the fastener and to pass over the bore wall upon rotation in the opposite direction. The lock ring has a slip plane to permit contraction of the ring to a diameter no greater than the major diameter of the fastener and expansion of the ring when the fastener undergoes moments tending to loosen it. The fastener proper may be a stud or an insert. An external chamfer of the ring bears against a cooperating internal surface of the workpiece to positively determine the axial location of the insert with respect to the workpiece.

Abstract: A vehicle mascot is mounted on a support to project through an aperture in the vehicle radiator shell. The support is pivotally mounted on the shell and a spiral spring acts to bias the support into a retracted position in which the mascot is almost wholly retracted into the radiator shell. The support and mascot are maintained in a non-retracted position by a detent which acts to prevent movement of the support under the action of the spiral spring. The mascot is connected to an actuator which, on deflection of the mascot more than, say, 25% from its normal upright position, against the biasing action of a compression spring constrained to act between the support and the actuator, releases the detent to allow the spiral spring to retract the support and mascot.
