A lock mechanism (10) for a scaffolding clamp or coupler (33) having a threaded rod (15) and a securing nut (14) is disclosed. The mechanism deters unauthorised removal of the securing nut and has a locknut (12) engageable with the threaded rod and having an unconventional drive mechanism (17). The mechanism also has a substantially cylindrical hollow sleeve (13) with a cylindrical interior dimensioned to surround the securing nut and locknut. The locknut has a main body with a tapered nose (21) able to bear against the securing nut and an annular recess (23). The sleeve interior has an inwardly projecting substantially annular flange (26) through which the nose can be forced to locate the flange in the recess and thereby retain the sleeve on the locknut. In addition, the sleeve has an exterior which is smooth and devoid of projections and recesses, and an axial length greater than the combined axial lengths of said securing nut and locknut, to thereby shield both the securing nut and the lock nut. A cup shaped shield (40) and cap (45) for masonry bolts (37) is also disclosed.

Provided is a center bracket for fixing a fire sprinkler and, more particularly, to a sprinkler center bracket having a one-touch-type structure, to which a locker for preventing loosening of a cam lever is coupled. When a locker protrusion is inserted into a locker protrusion hook groove formed in one end portion of a cam protrusion contact portion, wherein the locker protrusion is rotated about a fixing tool of the locker for preventing loosening of the cam lever as a central axis of rotation, the cam lever is rotated in a locking direction in order to fix the sprinkler, and after this, loosening of the cam protrusion contact portion in a direction opposite to the locking direction can be prevented, the cam protrusion contact portion being fixed by an elastic spring hinge pin after the cam lever is rotated in the locking direction to fix the sprinkler.

A pet treat holder comprising a body, a clamp, a gripper frame, and a treat gripper, and a method of providing a pet treat to an animal.

The track is elongate such that it extends along a longitudinal axis. The track comprises an alignment feature located at a predetermined alignment position along the longitudinal axis of the track. The alignment feature is configured to secure a partition support member at the alignment position when the partition support member is received by the track. The alignment feature comprises one of a projection or recess configured to engage with the other of a projection or recess of the partition support member.

An easily modified bathing chair comprises: two side connecting pedestals, having a beam, two beam tubes and two leg tubes respectively; four legs which are fixed in the leg tubes of the two side connecting pedestals, respectively; a seat, having two front slides and two rear slides on a bottom thereof, wherein the two front slides each have a first seat positioning structure; and a long upper beam set and a short upper beam set, wherein either the long upper beam set or the short upper beam set is slidingly mounted on the seat and set between the beam tubes of the two side connecting pedestals, thereby it is achieved that a bathing chair of any of two types is assembled conveniently.

Described herein is a method for mounting a grid hanger assembly of a ceiling system. The ceiling system, in one embodiment, includes a grid support member, ceiling panel, and grid hanger configured to support the grid support member in a suspended manner from an overhead structural support. The grid hanger includes a mounting bracket configured for attachment to the structural support and a hanger member. The hanger member is adjustable in a plurality of selectable mounting positions relative to the mounting bracket, thereby allowing the mounted height of the grid support member to be adjusted in the field. In some embodiments, the hanger member is further angularly adjustable relative to the mounting bracket to avoid installation obstacles.

A bicycle handlebar stem includes a body having a connection portion and a top clamp respectively formed on two ends thereof. The body includes a space defined therein, and an opening communicates with the space and outside of the body. A bottom member has a tongue extending inserted into the opening and the space. A bottom clamp is formed to the bottom member and includes an upward portion extending upwardly and toward the downward portion of the top clamp. A passage is defined between the top clamp, the bottom clamp and the body so as to receive a handlebar. A connection member extends through the body and the tongue to connect the bottom member to the body. Two fasteners extend through the underside of the bottom clamp and are connected to the top clamp.

A brace pipe attachment mechanism includes an attachment device defining an attachment device body, the attachment device body comprising: an inner surface defining a brace pipe channel, the inner surface defining a gripping edge at least partially encircling the brace pipe channel; and a base portion, wherein a base fastener hole extends through the base portion to the brace pipe channel; and a fastener extending through the base fastener hole and into the brace pipe channel.

The present invention provides a clip-shelf fixer, comprising a pipe clip with two side clip-claws on both sides, which a bayonet is formed between the ends of the two side clip-claws and a pipe cavity is formed between the two side clip-claws, wherein the two side clip-claws on both sides are provided with a first portion of the two side clip-claws and a second portion of the two side clip-claws along the axial direction of the pipe cavity; there is an gap between the first portion and the second portion of the two side clip-claws, which is compatible with mesh wires of mesh plate, and at the end of the gap a first mesh wire connection part perpendicular to the axial direction of the pipe cavity is provided; the first mesh wire connection part is provided with a first mesh wire cavity, and the first mesh wire cavity is connected with the pipe cavity to form an integral pipe and mesh wire connection cavity. The present invention can connect the supporting pipe with the mesh plate steel wire intersecting with it, and each supporting pipe can be connected with the matched mesh plate on the support pipe, so as to avoid missing connection; and the overall structure of the clip-shelf fixer can be further strengthened by combining with the parallel steel wire connection structure.
