Abstract: The present invention provides a fastener adapted to be secured to a first member for fastening a keeper secured to a second member. The fastener comprises a base member, a sleeve member connected to the base member, and a slide member received within the sleeve member to be extended or withdrawn. The sleeve member is included with an opening into which a cam mechanism is received for rotatable movement. A cam member is also provided extending from the cam mechanism and into a cam opening provided in the slide member. The fastener also includes a turning member which is adapted to rotate the cam mechanism so as to move the cam member within the cam opening in order to extend or withdrawal the slide member. The fastener may also include a biasing member confined within the base member in order to bias the sleeve member relative to the base member as the slide member is fastened with the keeper. In addition, the fastener may be adapted for increasing the amount of extension or withdrawal of the slide member.

Abstract: A metal industrial fastener comprises a keeper plate having a hook-like keeper lip attached to one panel and a turn hasp member attached to another panel, which turn member may be recessed in a dish. The turn member has a spring which spring-loads a spring-back hook member, a base member fixed in a dish to a panel, a slide member which telescopically slides in the base member, and a turning means to rotate an eccentric rivet which cam-operates the slide member.

Abstract: A fastener removably clamps the edges of two panels each having a hole therethrough. The fastener includes a hinge pin, about which the fastener body pivots. To clamp the panels, the hinge pin is extended through the holes in both panels to align the panels and then the fastener body is pivoted so that its top flange portion lies on one panel and its bottom flange portion lies on the other panel, thereby clamping the panels between the two flange portions of the fastener.

Abstract: An industrial quarter-turn fastener assembly comprises a sheet metal turn member having a turn head, a shank portion and a nose portion; a cap member through which the shank portion extends; and a helical coil spring. In one embodiment the fastener assembly is a blind fastener which is tilted to pass through a hole in a first panel which hole is smaller than the width of the nose portion and in another embodiment the shank portion is held to the first panel by a locking ring. To secure a second panel to the first panel, the nose portion is pushed through a slot hole in the second panel and the fastener turn head is rotated a quarter turn.

Abstract: A fastener to removably secure two panels consists of a spring-loaded toggle latch (catch unit) on one panel and a keeper plate (strike) with a keeper lip on the other panel. The toggle latch comprises a pivot bracket with a flat base plate and opposite upstanding side ears, a pivotable operating lever (handle) and a pivotable hasp member (draw bar) having a downwardly turned lip at its free end to engage the keeper lip. The three members of the toggle latch are solely joined by left and right single-turn coiled torsion springs which spring-load the hasp member. In one embodiment the flat base plate of the pivot bracket has two openings, each with a series of staggered indentations forming pairs of indentations, which indented pairs are differently spaced from the edge of its panel, to permit adjustable mounting of the pivot bracket on its panel.

Abstract: A fastener for removably securing a plurality of panels includes a stud member having a top turning means, such as a flat handle, a central shank portion and a bottom camming (knob) portion. The fastener, upon being rotated, is moved along its axis by ramp means secured to a panel. The camming portion acts against the internal walls of spreadable flexible finger members to spread them outwardly and thereby grip the other panel.

Abstract: A fastener includes a plastic strike having a rounded flange and a fastener body assembly comprising (i) a plastic fastener body member having an integral raised portion with a cam area; (ii) a plastic handle member having a gripping portion, a central portion having a cam face and an extension portion having a hook-like member; and (iii) means connecting the fastener body member and the handle member to permit translation and rotation of the handle member.

Abstract: A releasable locking fastener for industrial applications comprises a turn member which may be rotatably attached to a first panel and a receptacle member which may be fixedly attached to a second panel. The turn member includes cap and stud members which are fixed together to form a unitary member, a means for resiliently and rotationally positioning the turn member with respect to the first panel, and a means for securing the turn member to the first panel. The stud member is a unitary member, preferably formed from sheet metal, which includes a laterally disposed head portion, a body portion, and a nose portion. The receptacle member comprises a base having two downwardly projected spring flanges, an opening and a means for securing the receptacle member to the second panel.

Abstract: An industrial fastener, which may be secured or released by a one-quarter turn, includes a rotatable bolt. The bolt has a cam face on the underside of its head, a shank having opposite flats and a screw threaded end portion. A turning means, such as a handle member, slides on the bolt and has matching opposite flats to turn the bolt. The fastener also includes a spring which detents the handle member and an adjustable nut.

Abstract: A releasable locking fastener for industrial applications comprises a turn member actuator which may be attached to one panel and a receptacle member which may be attached to another panel. The turn member actuator includes a turn member, a retention means and a flat spring for resiliently disposing the turn member. The turn member is stamped as a unitary member from sheet metal and comprises a turning head means, an upper shank portion having a retention means seat, a middle shank portion having indentations, and a lower shank portion preferably having one or two cammed shoulders and terminating in a rounded nose. The receptacle member includes a base having an elongated opening, an indentation in the base transverse to the opening, and a plurality of stops protruding from the base.

Abstract: A locking industrial fastener comprises a hook-like keeper plate member having a keeper lip to be attached to one panel and a turn hasp member attached to another panel. The turn member comprises a sleeve member hinged to a fastening plate, a slide member which telescopically slides in the sleeve member, a cam pin operable in a cam opening in the sleeve member, a first disk rotatable in a circular opening in the sleeve member, a second disk fixed to the first disk, a spring disk fixed to the other disks, and a turning means.
