A joint assembly for joining structural members in a building frame can comprise: a marriage strap including one or more through-holes; one or more fasteners configured to be inserted through the one or more through-holes of the marriage strap; and a cube coupling joint including one or more recessed channels sized and shaped to receive a portion of the marriage strap, one or more fastener holes located within the one or more recessed channels and configured to receive and secure to the one or more fasteners. In some embodiments, the marriage strap is configured to be inserted into the one or more recessed channels of the cube coupling joint and the one or more fasteners are further configured to be inserted into and secured to the one or more fastener holes of the cube coupling joint.

A connector assembly is used to attach the end of a horizontal rail to the supporting vertical post of a barrier. A flat platform is secured to the side wall of the post. A channel-shaped bracket having a convex base is seated within a concavity formed in the platform. A convex retainer is seated within the concave base of the bracket channel. A bolt extends through aligned openings formed in each of the platform, bracket and retainer. The bolt also extends through aligned openings in the post. The end of a rail is installed within the bracket channel, and held in place by a bolt. An elongate opening formed in the bracket base allows the bracket to swivel horizontally to a desired angular position. The bracket permits a single post to support adjacent sections of a barrier that intersect at a non-straight angle.

The invention relates to a locking device designed to lock objects to tubes or other elongated elements. The locking device generally comprises one or more lock plates and lock housings. In one exemplary embodiment, when assembling the locking device to a tube, two lock housings are put together with open sides against each other around a tube with a dimension corresponding to approximately half of a recess which is found on the lock housing's sides and are oriented in the tube's axial direction. The two lock housings form a closed geometry around the tube. Lock plates are used to connect the two lock housings together. By applying a screw in a threaded hole in one of the lock housings' cover, the through tube is pressed against an opposite lock housing at substantially the same time as the lock plates hold the lock housings together.

An aluminum-extruded frame curve module structure includes at least one coupler and at least one curved board. The coupler includes a connection bar and a connection block connected thereto. A side of the connection block that is not connected with the connection bar is provided with a first fitting section. The curved board has a side that is provided with a second fitting section and an opposite side that is provided with a third fitting section. The second and third fitting sections are selectively connected with the first fitting section of the coupler. In this way, the connection bar of the coupler is connectable with an aluminum-extruded plate and the connection block of the coupler is connectable with the curved board. Two aluminum-extruded plates can be jointed to each other with more than one curved board therebetween to provide a curved form at a desired angle for extension and assembly.

A cabinet includes a structural frame including a plurality of connecting rods and a plurality of connector modules each of which includes first and second connectors. The first connector includes two first main plate portions perpendicularly connected to each other, a first fastening hole, and a limiting indented portion. The second connector includes a second main plate portion perpendicular to the first main plate portions, a seat body connected to the second main plate portion and having a first fastening hole corresponding in position to the first fastening hole of the first connector, and a limiting protruding portion protruding from the second main plate portion and having a shape complementing with that of the limiting indented portion.

A pipe rack system and a multi-plane coupling for such a pipe rack system are provided. The multi-plane coupling includes a coupling body that forms at least a first receiver aligned with a first axis, a second receiver aligned with a second axis, and a third receiver aligned with a third axis. The pipe rack system includes pipe sections that are received and coupled in the receivers. The multi-plane coupling may be in the form of a three-way, four-way, five-way, or a six-way pipe fitting. The receivers may be female threaded sockets. The pipe sections may be threaded pipe that are threadedly received within the female threaded sockets of the pipe fittings.

A locking mechanism comprises an S-shaped locking member which comprises respective locking hooks arranged at the end of opposed arms of the locking member. A pivot is arranged between the arms of the locking member. The locking member rotates around the axis (A) of the pivot. The locking mechanism further comprises a coupling for coupling the locking member to an actuator for rotating the locking member around the pivot axis (A). The coupling comprises at least one coupling element, an actuator coupling for coupling the at last one coupling element to the actuator and first and second drive couplings for coupling the at least one coupling element independently to each arm of the locking member for transmitting rotational movement thereto, such that failure of one arm of the locking member will not cause loss of drive to the other arm of the locking member.

A load anchor assembly for attachment to a tubular member having an exterior surface, comprising an anchor base and a portion extending from the anchor base adapted to secure a vehicle component. The assembly includes a boss having a first flanged end and a second end, where the boss is adapted to be positioned in first and second apertures in the exterior surface of the tubular member with the flanged end in contact with the first aperture and the second end accessible through the second aperture. There is at least one fastener connected to the anchor base and the second end to secure the anchor base to the flanged boss.

A connector assembly, having an upper connector coupled to a lower connector and a gusset plate sandwiched between the upper and lower connectors. Also, disclosed is a hoistable connector assembly, a lifting frame assembly, a coupling system for modular frame units, a method for assembling a module unit using the connector assembly, and a modular frame unit and building having the connector assembly.
