A channel fastener for fastening to an elongate channel element including a washer element, an oblong anchoring element and a connecting element which connects the anchoring element to the washer element, while allowing the anchoring element to rotate with respect to the washer element. The fastener includes a torque-inducing element fixed to the anchoring element and includes at least one resiliently deformable limb arranged substantially offset from the rotational axis of the anchoring element and adapted for a sliding engagement with a flange of the channel element. When the anchoring element is inserted through the longitudinal slot into the channel element, the limb deforms while sliding along the flange towards the interior of the channel element, whereby a torque on the anchoring element is induced, which rotates the anchoring element towards a locking position in which it cannot be retracted through the longitudinal slot of the channel element.

A bow stop is an apparatus that safely aids in the docking of a boat. The apparatus includes at leas tone length-adjustable stopper assembly. The at least one length-adjustable stopper assembly includes a telescopic bar, a stopper tube, a bungee cord, a first cradle mount, and a second cradle mount. The telescopic bar adjusts to the length of a boat. The stopper tube presses against the front of the bow. The bungee cord retracts the stopper tube into a neutral position. The first cradle mount and the second cradle mount secure the telescopic bar, and consequently the stopper tube and the bungee cord with the cradle mount. In a preferred embodiment, the at least one length-adjustable stopper assembly is a left length-adjustable stopper assembly and a right length-adjustable stopper assembly. The preferred embodiment further includes a length-adjustable cable, connecting the left length-adjustable stopper assembly with the right length-adjustable stopper assembly.

The beams, legs, and brackets are all configured so that the beams and legs are easily connected together for platform system creation.

A Three-Dimensional Positioning and Holding Modular System for office and industrial work stations including embodiments of multi-rail beams and rail-arm-leg modules. The embodiments have tubes, bars, or channels arranged and connected in ways that provide improved ability to transmit torque along a long axis of the multi-rail beam while providing improved resistance to twisting under the forces of the torque.

A multi-directionally engageable column combination structure comprising a column, a first hook body, and a second hook body. The column is in a straight cylindrical shape and has an outer circular surface and two end faces. A plurality of axial combination grooves are disposed at the outer circular surface, and the combination groove has an opening, a first catching groove and a second catching groove; a front end of the first hook body has a first hook portion, a rear end of the first hook portion has a first engaging portion, a front end of the first hook portion has a first hook pillar, a first hook edge is disposed at a front end of the first hook pillar, an abutting edge is disposed at a position that is on the first hook portion and corresponds to the outer circular surface of the column; a side of the first engaging portion has a first engaging surface, and a first combination hole is disposed on the first engaging surface; a front end of the second hook body has a second hook portion, a rear end of the second hook portion has a second engaging portion, a front end of the second hook portion has a second hook pillar, a second hook edge is disposed at a front end of the second hook pillar, a side of the second engaging portion has a second engaging surface attached against the first engaging surface, and a second combination hole is disposed, the first and second hook edges of the first and second hook bodies hook the first and second catching grooves respectively, and then engaging elements are inserted into the first and second combination holes for combination. Thus, better assembly convenience and stability are achieved in the present application.

In various representative aspects, an apparatus for clamping and grounding solar panel frames to a mounting rail is disclosed herein. The apparatus includes a fastener with an enlarged end, and a shank, with the enlarged end having one or more sharp protrusions that resemble teeth, and a washer with one or more sharp protrusions, and an opening. When installed, the shank is inserted through the opening of the washer, the sharp protrusions of the enlarged end penetrate either the lower or upper surface of the mounting rail and the sharp protrusions of the washer penetrate the other surface of the solar panel frames while at the same time creating a grounding path through the apparatus.

A walkway installation includes a walkway assembly which includes at least one tread module supported by a pair of spaced apart elongate supports which extend in the direction of the length of the walkway installation, the walkway installation additionally including a handrail assembly including a handrail which extends in the direction of the length of the walkway assembly and a plurality of spaced apart posts which each secure the handrail relative to the walkway assembly, the handrail assembly additionally including a first connector which secures a post to one side of the walkway assembly and the first connector having secured thereto a substantially inflexible transverse link which extends across the walkway assembly in a direction perpendicular to the length of the walkway installation, the transverse link extending to a second connector secured to the other side of the walkway.

The present invention relates to a slidable mounting block for insertion into a rail having a partially closed profile, the mounting block having a front face and a rear face opposite to the front face, the front face facing an open part of the partially closed profile when inserted into the rail. The mounting block comprises a first hole accessible from the front face in a first fixing area of the mounting block and configured for screwing in a threaded part of a first fastener, a recess accessible from the rear face in a second fixing area of the mounting block and configured for holding a head of a second fastener, and a second hole accessible from the front face in the second fixing area, the second hole being co-aligned with the recess and configured for passing a shaft of the second fastener through the mounting block.

A connector for attachment of two frame elements in a framing system has a connector body of similar rectangular section to the frame elements. A flat inner engagement face of the connector body engages with a flat end face of a first frame element, and essentially forms an extension of the first frame element. An outer engagement face of the connector body is substantially parallel to the inner engagement face and in use abuts against a flat side wall of a second frame element. The outer engagement face has two outwardly projecting lips along opposite side edges of the connector body at the outer face. Each lip has a curved inner face for engagement with opposed radiused edges at opposite sides of the flat side wall face of the second frame element. A flat outer face of the lip forms an extension of a side wall of the connector body and provides a smooth transition between adjacent side walls of the two frame elements. Thus, advantageously, there is no groove forming a dirt trap between the two frame elements when they are interconnected.
