A quick disconnect mount includes a mounting stud securable to a structure, and a connector securable on the mounting stud. The mounting stud includes at least one circumferential ridge and at least one circumferential trough, and the connector includes a central channel sized to fit over the mounting stud and a locking bar engageable with the circumferential trough.

Provided are a connector and a connection system for concrete barriers. The connector is configured to slip-fit into a cross-shaped gap formed between the concrete barriers. The connector includes a saddle member and a fork member. The saddle member includes a base plate and peripheral plates. The peripheral plates extend at angles from the base plate to define a channel extending along the length of the base plate. The fork member extends from the base plate of the saddle member. The fork member includes an elongated base, flanges, and legs. The elongated base extends in the channel between the peripheral plates at least along the width of the base plate. The flanges are transverse to the elongated base forming a cross-shaped structure disposed in the channel with the flanges that extend toward the open ends of the channel. The legs extend separately from the elongated base.

Disclosed are a connecting structure and a cat furniture item. The connecting structure includes: a first connector, configured to be fixed to one of an end surface of a column and a panel, and provided with at least one slot; a second connector, configured to be fixed to the other one, and provided with at least one block. The at least one block is configured to engage with the at least one slot respectively to achieve a detachable connection. Based on the connecting structure, the efficiency of disassembly and assembly between various components of the cat furniture item can be improved. In addition, additional fixing components such as screws are unnecessary, so that the accidental injury caused by exposure of screws can be fundamentally avoided.

A vehicular module attachment assembly includes a vehicular cabin module having a peg that includes a foot. A locking device is slidably coupled to the peg. A slot is formed in a cabin floor including first and second grooves configured to retain the foot. The locking device adjusts between an unlocked position, wherein the peg is slidable between the first and second grooves, and a locked position, wherein the peg is retained in the second groove

The present disclosure relates to an axle retainer and associated conveyor system. An example axle retainer is defined by a housing that includes a first surface configured to be secured to an inner-sidewall of a conveyor frame and a second surface opposite the first surface. The second surface defines two or more apertures configured to mount a conveyor roller axle therein. Each aperture includes a snap-fit bracket defining two arms each with a corresponding protrusion. The two arms of the snap-fit bracket are configured to expand from a first position to a second position within the aperture to receive a conveyor roller axle and rebut from the second position to the first position such that the pair of corresponding protrusions defined by the two arms of the snap-fit bracket retain the conveyor roller axle in the aperture.

To provide a fitting member, an annular member, a joined member and a method of manufacturing the joined member, which prevent occurrence of a not-joined portion. A fitting member 10 has a fitting protrusion 10p which is protruded outward on an outside face 10s. An annular member 20 contains a space 20h in which the fitting member 10 is to be fitted. An annular member 20 has an annular protrusion 20p on an inside face 20f. When the fitting member 10 is fitted into the space 20h at a predetermined depth, the fitting protrusion 10p and the annular protrusion 20p fill not-joined portions which may be generated assuming that they are not provided. A joined member 30 is produced by fitting the fitting member 10 into the space 20h at the predetermined depth, so that a contact portion between the fitting member 10 and the annular member 20 is joined in solid phase.

A support pin is engaged with a collar, as affixed to a mount, by an engaging mechanism between the support pin and the collar, which engaging mechanism provides interchangeability, index-ability and positive locking between the support pin and the collar. Motion picture lighting and rigging equipment is secured to the support pin. The engaging mechanism includes a V-shaped or other configured reception on or in the collar with a cross-pin or similarly other configured portion on the support pin (e.g., non-circular cross-sectional configurations such as a hexagon). A linchpin is placed though mating openings in the collar and support pin to lock the two together when the mating openings are aligned. Two or more crossing V-shaped receptions or non-circular cross-sectional configurations provide a variety of angular orientations of the support pin, especially for bent support pins, with respect to the collar.

A display support system is provide and includes a node connector and a support connector secured to the node connector. The node connector includes a plurality of intersecting planar surfaces that form the outer surface thereof. The support connector is releasably securable to the node connector along one of the plurality of intersecting planar surfaces.

A guard rail system is provided. The guard rail system includes a bracket portion adapted to at least partially surround at least a portion of a track of a machine. The guard rail system includes at least one retention device provided in association with the bracket portion. The at least one retention device is adapted to removably affix the bracket portion to the portion of the track. The guard rail system also includes at least one receiving unit located on the bracket portion. The guard rail system further includes a rail member adapted to be removably affixed to the at least one receiving unit.

A marker assembly is provided. The marker assembly is attachable to a roof or roof element to alert a worker to potential hazards nearby. For example, the marker assemblies may be attached to a roof, such as a corrugated roof, adjacent to four corners of a skylight, to alert a worker that the skylight may be nearby, particularly in the event that it may be buried or otherwise hidden or obscured. A transmitting beacon within the marker holder which may provide an output signal receivable by a computerized receiver. Upon receipt of the output signal by the computerized receiver, the computerized receiver can provide a notifying output.
