A quick-release fastener structure includes a body portion and an engaging portion. The body portion is fitted to a first object. The engaging portion is movably fitted to the body portion. The engaging portion has a head portion, a bar portion with an end connected to the head portion, and an engaging-connecting portion disposed at another end of the bar portion. The engaging-connecting portion is insertedly engaged with or separated from a second object. Therefore, the quick-release fastener structure operates by fitting the body portion to the first object and allowing the engaging portion to be engagedly connected to the second object or removed from the second object, such that the at least two objects are coupled together and separated repeatedly and quickly.

An acousto-optic device may include an acousto-optic component carried by a chassis, and a fastener assembly for removably securing a cover to the chassis. The fastener assembly may include a base sleeve having an enlarged head, and a tubular body and extending through a cover passageway. The fastener assembly may include a retainer sleeve having a threaded interior secured to the threaded exterior of the base sleeve to define an anchor member, the anchor member having a threaded interior. The fastener assembly may further include a fastener, a shaft having a threaded exterior opposite the enlarged head and to be threaded through the threaded interior of the anchor member to capture the fastener to the cover and movable through the chassis passageway for removably securing the cover to the chassis.

A mounting assembly for use in mid-grab and/or edge-grab applications may include a clamp secured to a stanchion by a clamping fastener. The mounting assembly may also include a mounting plate which may be secured to a mounting device by the stanchion. The mounting assembly may be used, for example, to secure photovoltaic modules (or other devices or structures) of varying heights to a roof or other building surface.

A fastener operating structure includes a holding base and a fastening-connecting unit. The holding base is disposed at a first object. The fastening-connecting unit is movably disposed at the holding base. The fastening-connecting unit is fastened to a second object. Consequently, the holding base is disposed at the first object, and the fastening-connecting unit is coupled to or removed from the second object, so as to couple together and separate the first and second objects repeatedly and quickly.

An apparatus for securing a panel to a structure is provided. In one embodiment, the fastener includes a fastener having a fastener head and a threaded tail, and the fastener may be disposed through a structure and an external panel. The apparatus also includes a retainer housing positioned on the fastener head, where the retainer housing is detached from the fastener. A spring engaging the fastener and the retainer housing is also included within the retainer housing.

A fastener includes a base member; a first member, on the base member and having a through bore; a second member, on the base member and spaced from the first member to form a receiving portion to receive a panel structure, including an aperture defining an internal surface, the internal surface including at least one stop member protruding radially inwardly, and a nut member, coaxially aligned within and frangibly connected to the internal surface, including at least one block member protruding radially outward from an outer surface of the nut member to stoppingly engage with the at least one stop member. During use, the nut member moves from a first position, where the nut is frangibly connected to the internal surface, to a second position, where the least one block member abuttingly engages with the at last one stop member.

Disclosed is a system for connecting two panels together. A recess is formed in the edge of one panel, and an insert is pressed into and held within the recess. The top of the insert includes holes for receiving epoxy, and epoxy conducting shafts and circuits formed on the outside of the insert assist in the encapsulation of the insert within the panel edge. The top of the insert includes an aperture formed such that a fastener can be received into a cavity formed in the recess and then driven to be secured into a fastener-receiving insert installed into the second panel.

A removable fixing device 1 for fixing equipment A on a support B, with: a compressible planar piece 5, an operating lever comprising a cam lever 2, and an assembly rod 3 having a first end and a second end; with: the second end of the assembly rod 3 being provided with a tightening means (4); the compressible planar piece 5, said operating lever comprising a cam lever 2 and the tightening means 4 arranged in tightened position being disposed around the assembly rod 3 in an assemblage; said operating lever comprising a cam lever 2 being arranged so that a rotation of the cam lever 2 about an axis y at right angles to the axis z of the assembly rod 3 induces a displacement of the cam lever 2 between a tightened position and a loosened position.

An information handling system may include a battery, a circuit board, an enclosure, and a control circuit. The circuit board may include at least one electric component, a first electrically conductive pad, and a second electrically conductive pad in proximity to the first electrically conductive pad. The enclosure may be configured to house components of the information handling system including the battery and the circuit board, and the enclosure may include a first member, a second member configured to be mechanically coupled to the first member, and a mechanical component comprising conductive material and configured to electrically short the first electrically conductive pad to the second electrically conductive pad when the first member is mechanically coupled to the second member, and cause electrical isolation of the first electrically conductive pad from the second electrically conductive pad when the first member is mechanically decoupled from the second member. The control circuit may be configured to, when the first electrically conductive pad is shorted to the second electrically conductive pad, cause the at least one electrical component to be electrically coupled to the battery and when the first electrically conductive pad is electrically isolated from the second electrically conductive pad, cause the at least one electrical component to be electrically decoupled from the battery.

A captive fastener including a bushing having a body portion and an internal bore extending through the body portion A snap ring is mounted within the internal bore. A fastener having an elongated shaft is mounted within the bore and is adapted to reciprocate within the bore between retracted and extended positions. The elongated shaft has a shank diameter and threads formed on one end of the fastener. The snap ring engages the bolt when the shaft is extended and retracted. The fastener has a shank diameter which is 0.020 inches to 0.060 inches shorter than the bore diameter so that the fastener can be moved laterally within the bore.
