  • Patent number: 4156512
    Abstract: Equipment for use with hand-held motion picture and video cameras comprises a pair of interconnected spring loaded arms, one end of which is pivotally supported by a carrying brace worn by a cameraman and the other end of which is connected to a handle positioned to mount the camera equipment at approximately the center of the moment of inertia. The camera and its associated equipment are mounted in exploded, balanced relation about the handle. The weight of the camera equipment is substantially counterbalanced by the action of the spring loaded arms without employing counterweights. A camera viewed is provided with an extended, flexible cord to facilitate viewing from a position remote from the camera itself and not necessarily governed by the camera orientation.

  • Patent number: 4137817
    Abstract: A blind rivet comprising a sleeve with a preformed rivet head at one end, and a setting pin telescoped into the sleeve and having a pulling section projecting beyond the headed end of the sleeve and an expanding head projecting beyond the other end of the sleeve, to be pulled into the sleeve from the headed end thereof to expand the other end of the sleeve into a bulb-shaped rivet head against one side of two workpieces that are to be riveted together, the pulling section being broken off after the rivet is set, in response to engagement of the expanding head with stop means in the sleeve. The expanding head has an expanding shoulder for initiating expansion of the sleeve, and a taper beyond this shoulder which progressively increases the diameter of the head toward its free end.

  • Patent number: 4133246
    Abstract: A screw and nut assembly for adjustably positioning a headlamp unit relative to a support plate so as to realize proper optical aim for the headlamp unit. The assembly includes a one-piece plastic nut member having a shank insertable into a mounting hole formed in the support plate. The shank has one end formed with a base section and has the other end provided with a pair of spring arms which extend rearwardly along diverging axes towards the base section. The free end of each spring arm terminates with a plurality of teeth so that after the shank is inserted into the mounting hole in the support plate the spring arms move laterally outwardly to cause the teeth on each arm to engage the outer surface of the support plate and thereby hold the nut member in place.

  • Patent number: 4120231
    Abstract: A hollow wall fastener for insertion in a hole formed in a wall panel between the inner and outer faces comprises an elongated body adapted for longitudinal insertion into the panel hole. The body includes a pair of spaced apart, parallel, legs interconnected by an integral transverse cross member. A toggle element is pivotally mounted adjacent inner end portions of the legs for movement about a transverse pivot axis between the legs. The toggle is pivotable from a first position aligned with the legs during insertion of the fastener and a second position generally normal to the legs wherein a face of the toggle element is adapted to bear against the inside surface of the wall after the element clears the hole on insertion. A deflectable finger is integrally formed on the transverse cross member and includes a free end portion extending between the legs for biasing the toggle element from the aligned position during insertion towards the toggle locking position after the toggle element has cleared the hole.

  • Patent number: 4119131
    Abstract: A stud-like panel fastener with a wire-spring holdout for retaining the fastener in a retracted position on a panel. The fastener is formed with a bore extending from its leading end and a longitudinal slot at the lower portion of the fastener body in communication with the bore. A generally U-shaped wire spring member is carried within the bore with a lower protruding bearing surface on one leg of the member extending through the slot and beyond the periphery of the fastener body. When the fastener is retracted, the bearing surface of the spring member, in contact with the sidewall of the panel opening, holds the fastener against downward movement. Owing to the advantageous construction, the holdout is self-cleaning, as the sidewalls of the slot tend to wipe the bearing surface in use, and debris cannot build up behind the holdout and render it inoperative due to the large void behind the bearing surface. Also, the holdout can be quickly installed or replaced without special tools.

  • Patent number: 4115912
    Abstract: A fastening element assembly includes a fastening element having a head and an axially extending shank, a ring-shaped elastic member laterally enclosing at least an axial part of the shank, and a washer located on the shank between the elastic member and the head. The elastic member can be in contact with the surface of the shank or spaced radially outwardly from it. When using the assembly to attach an object to a support material, an opening or hole is formed in the object with the opening having a diameter approximately the same size as the outside diameter of the elastic member. The fastening element assembly is driven through the opening in the object into the support material so that the elastic member seats in the opening and spaces the shank from the object. Any transverse forces acting on the object are damped by the elastic member before they reach the shank.

  • Patent number: 4112993
    Abstract: A two piece grommet assembly comprising an inner and an outer member wherein each member has an enlarged head at one end formed to bear upon opposite sides of a panel skin. The outer member has a recessed area intermediate its ends and the inner member has a weakened section on the shank portion which is adapted to deform into the recessed section of the outer member upon the application of opposing axial force on the two members. The weakened section of the inner member is comprised of a reduced cross-sectional thickness portion which collapses upon the application of axial force, causing the reduced thickness portion to flow inwardly into intimate contact with the recess in the outer member, locking the members together in the panel skin.
