A system can include a display assembly that includes a display, a display side, a back side and a frame, where the back side includes a serial bus socket; and a camera assembly that includes a camera head unit coupled to an end of an arm, where an opposing end of the arm includes a serial bus connector receivable by the serial bus socket of the back side of the display assembly.

An electrical connection assembly includes an electrical box including a housing having an internal surface defining an internal volume of the housing. An electrical connector is positioned outside the internal volume of the housing and fixed to the housing with a fastener. The housing includes an aperture having an opening defining an insertion path extending from a location external to the housing along a frame of the electrical connector to a location within the internal volume of the housing. The assembly includes a disc mechanically secured to the housing relative to the opening to obstruct the insertion path. A retainer and a bushing including a membrane for the electrical connector as well as methods of making an electrical connector are also provided.

Wall mounting bracket for mounting an elongate mounting rail as a cantilever arm to a wall or other supporting surface including a wall plate having mounting holes for mounting the bracket to a wall by means of male fasteners; a socket for inserting the end portion of the mounting rail, including at least two flange profiles, which at their distal end have an embracing portion to interlock with the end portion of the mounting rail thereby inhibiting movement of an inserted end portion parallel to the wall plate. At least one of the embracing portions has a fixing hole for passing through a male fastener to fix the end portion of the mounting rail to inhibit retraction of the end portion from the socket; a supporting rim within the socket, configured to interlock with the outer or inner side of the end portion of the mounting rail.

The invention comprises a scalable and foldable multipurpose frame structure configured with a generally flat-roof as a worksite and a peaked-roof as a recreational canopy, a cover retaining system and a ventilation system. The frame structure comprises a plurality of foldable wall trusses connecting a plurality of upright telescopic posts transversely forming a wall frame structure and a closed loop geometric footprint, a plurality of foldable roof trusses connecting a centrally disposed roof assembly to either the telescopic posts or the wall trusses transversely forming the roof. The cover retaining system comprises various spring clips for known-size frame members, and various clamps for unknown-size frame members, to secure roof and wall cover to the frame structure. The ventilation system comprises an enclosure that can utilize standard furnace air filters and existing air circulation devices. Multiple frame structures can be linked together to scale up space.

A wall mounting bracket for mounting a channel profile element to a wall surface includes a wall plate to be mounted to the wall surface, and at least one support for supporting an end portion of the channel profile element. The support is attached to and extends from the wall plate, The support includes at least one wall portion having fastening apertures. The support includes at least a first support profile and a second support profile. In use the first support profile bears against an exterior side of one of the opposing walls of the channel profile element and the second support profile bears against an interior side of the other one of the opposing walls of the channel profile element.

Disclosed is an assembly-friendly table frame, which relates to the field of lift tables. The table frame includes an upright and a base stand mounted to the underside of the upright; one of the base stand or the upright is securely coupled with a connecting member, and the other thereof is provided with a locking bump; the connecting member includes an insert-fitting rail and a locking slot provided in the insert-fitting rail; the locking bump is sequentially inserted into the insert rail and slid to be snapped into the locking slot; the table frame further includes an ejector member configured to eject the locking bump out of the locking slot. Further disclosed is a table applying the table frame. An advantage of the present disclosure lies in enhancing convenience of assembly and disassembly between the upright and the base stand.

A bracket useful for seismic bracing of conduits is described. The bracket is placeable over a threaded rod and includes sidewalls for accepting a fastener and a pair of apertures for attaching to a brace. Certain brackets are stackable, allowing for the attachment of multiple braces from a single anchored rod. Other brackets include two parts that allow the bracket to be assembled about a threaded rod without removing elements which might previously be attached to the rod.

A fitting for coupling an open upper end of a hollow section column to a support via which a building unit is to be supported on the column. The fitting comprises a body portion configured to be received in the open upper end of the column and rim portions that extend laterally outwardly from an upper end of the body portion so as to engage edge sections of the column at its upper end when the body portion is received in the open upper end.
