A removable bracket includes a generally planar body having a front face, a rear face, a first longitudinal side, a second longitudinal side, a first lateral side, and a second lateral side. Each of the first lateral side and the second lateral side extends between the first longitudinal side and the second longitudinal side and includes a lip extending outwardly from the front face. A lateral axis bisects the body and a longitudinal axis bisects the body. The body is symmetrical about each of the lateral and longitudinal axes. Two supports extending generally perpendicularly outwardly from the front face proximate to and on either side of the lateral axis. A kit includes a plurality of the brackets, and at least one of a rod, a first shelf, a plurality of extension pieces, and a second shelf.

A connecting bracket is disclosed which includes a base having first and second edges aligned at an angle to one another. A first member extends up from the first edge and a second member extends up from the second edge. Each of the first and second members has an end wall. A first tongue projects outward from the end wall of the first member and a second tongue projects outward from the end wall of the second member. The first and second tongues are designed to engage two frame members. Three or more frame members can be joined together in this fashion to form a frame assembly. A pair of frame assemblies can be used to secure at least three sidewalls of a structure to form an aquarium.

A tonneau cover and a method of attachment are disclosed herein. In some embodiments, a self-energizing clamp can be used to retain a tonneau cover onto a side wall of a truck bed, or other vehicle bed. In some embodiments, the clamp can be rotated between a usage position and a storage position in order to prevent the clamp from incidental movement or harm while accessing the truck bed.

Disclosed is a fastening system (10) for fastening two first and second profile bars (16, 18) which have a first and second groove (12, 14) respectively, comprising a fastening body (20) that has feather-key-like first and second projections (30, 32) which extend into first and second groove openings (34, 36) in the assembled state, the projections (30, 32) being provided with first and second screw bores respectively which extend into one of the respective groove openings (34, 36) in jaw-like manner, the respective first and second hammer heads each being freeform heads which impart a twist, the first and second shafts being located partially within the groove openings (34, 36) in the assembled state and first and second noses being arranged approximately diagonally to each other at each hammer head screw (22, 24) at the transition between hammer head and shaft, which noses lie against the jaw-like screw bores (38, 40) in the assembled state so as to inhibit rotation.

The invention relates to a coupling for connecting and/or holding together two parts, in particular for a bicycle trailer, having a first and a second coupling part which cooperate and can be released from each other, one of which is an insert piece which is connected to one of the parts and the other is a sleeve which is connected to the other part, the sleeve being capable of at least partly engaging around the insert piece, and the first coupling part having at least one locking groove (22, 103). To achieve a constructively simple coupling with a simple handling ability, mounted on or in the second coupling part is at least one locking shaft (4, 96) which has at least one locking segment having in the peripheral direction at least one locking portion (31, 131) and one unlocking portion (32, 132), the locking portion (31, 131) having a greater radial extent than the unlocking portion (32, 132). The locking shaft (4, 96) is arranged so that the locking portion (31, 131) can engage in the locking groove (22, 103) when the insert piece has been introduced into the sleeve, and the unlocking portion (32, 132) cannot engage in the locking groove (22, 103). Furthermore, means are provided for rotating the locking portion (31, 131) into the locking position, for holding the locking portion (31, 131) in the locking position and for releasing the locking portion (31, 131) from the locking position.

A removable bracket includes a generally planar body having a front face, a rear face, a first longitudinal side, a second longitudinal side, a first lateral side, and a second lateral side. Each of the first lateral side and the second lateral side extends between the first longitudinal side and the second longitudinal side and includes a lip extending outwardly from the front face. A lateral axis bisects the body and a longitudinal axis bisects the body. The body is symmetrical about each of the lateral and longitudinal axes. Two supports extending generally perpendicularly outwardly from the front face proximate to and on either side of the lateral axis. A kit includes a plurality of the brackets, and at least one of a rod, a first shelf, a plurality of extension pieces, and a second shelf.

The present disclosure relates to a locking and positioning mechanism and a rotational folding positioning apparatus. The locking and positioning mechanism includes a locking knob and a positioning pin. The locking knob is in a threaded connection with a side wall of a support sleeve, and the support sleeve sleeves a stand column; the locking knob can be screwed in and out relative to the support sleeve, and when the locking knob is screwed inward, an inner end of the locking knob presses tightly against the stand column for locking. The positioning pin is coaxially arranged through the locking knob, and the positioning pin can extend inward and outward relative to the locking knob; an elastic member is provided between the positioning pin and the locking knob. The mechanism is compact in structure, occupies minimal space, and is convenient and effortless to operate.

The present disclosure discloses a connector that can be used to connect fitness equipment and relates to the technical field of fitness equipment. The connector includes a first connection member and a second connection member that are hinged to each other, a clamp cavity configured to connect the fitness equipment is formed by enclosing the first connection member and the second connection member, a buckling structure configured to lock or unlock the first connection member and the second connection member is provided between the first connection member and the second connection member. Compared to a structure of locking a connector by screwing nut, the advantage of the present disclosure is that locking or opening is simple, convenient, and quick by flipping the buckle to fasten.

A connector for connecting elongated members has a connector body having two configurations. In a first configuration, the connector connects two elongated members in a fixed relative position. In a second configuration, the connector connects the two elongated members by selectively positioning one elongated member relative to a second elongated member. A threaded lock is provided that is operated to configure the connector in one of the two configurations.

Stacking storage arrangement including at least one container receiving space; a loading space which is arranged below the container receiving space; a frame assembly between the container receiving space and the loading space; and an upright on at least one corner of the container receiving space, which is connected to the frame assembly by at least one connecting device. The connecting device bridges an angle between the frame assembly and the upright and abuts the frame assembly in a clamping manner.
