The bearing structure for shelving comprises: —a vertical upright comprising a first metal section provided with at least a first longitudinal side and with at least a second longitudinal side, the first longitudinal side and the second longitudinal side being flat, continuous and transverse to each other; —a longitudinal cross-piece; —an angular bracket to be interposed between the vertical upright and the longitudinal cross-piece and comprising a first longitudinal face and a second longitudinal face, the first longitudinal face and the second longitudinal face being flat, contiguous and transverse to each other; wherein it comprises first connecting means arranged on the first longitudinal side and the first longitudinal face, and second connecting means, arranged on the second longitudinal side and the second longitudinal face, the first connecting means and the second connecting means coupling the angular bracket to the vertical upright.

A frame unit includes first and second bars spaced apart from each other, third bars disposed between the first and second bars, and connectors removably connecting the third bars with the first and second bars. A connector includes a body fixedly connected with the first or second bar, a casing defining an interior to receive an end of a third bar, and a slot allowing insertion of the end of the third bar into the casing. The interior defined by the casing has narrow and wide sides corresponding to the narrow and wide sides of the end of the third bar. As such, when the end of the third bar is inserted into the casing, the end of the third bar is prevented from any translational movement within the casing. The connectors allow quick and easy connection of bars, and in the meantime enhance the stability of the frame unit.

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.

A connecting device includes a case (1), a first rod (2), a second rod (3), and a third rod (4) that are connected to the case (1). Two first connecting members (5) connect the second rod (3) and the third rod (4) to the case (1). A second connecting member (6) connects the first rod (2) to the case (1). The case (1) includes an upper housing (101) and a lower housing (102) that define a first receiving hole (10), a second receiving hole (11), and a third receiving hole (9), the second connecting member (6) and the two first connecting members (5) are received in the first receiving hole (10), the second receiving hole (11), and the third receiving hole (9), respectively.

The present invention relates to the field of bed frame structures, and in particular, to a novel detachable bed frame assembly mechanism. The novel detachable bed frame assembly mechanism includes a bed frame body. The bed frame body includes an outer frame, an inner frame, and two sets of wooden strips. The outer frame is a rectangular frame including two horizontal tubes, two lateral tubes, four L-shaped iron-plate connectors, bolts, and nuts. The inner frame includes at least one horizontal connecting tube, a plurality of lateral connecting tubes, iron sheets, bolts, and nuts. The two sets of wooden strips are symmetrically disposed on the horizontal connecting tube and the horizontal tubes on both sides of the horizontal connecting tube and are parallel to the lateral tubes, to connect the horizontal connecting tube to the horizontal tubes. The invention is easy to assemble and disassemble and is safe and reliable.

A mechanism and method for quickly and easily interchanging various furniture bases with various furniture seats or seat boxes by means of an interlocking connection, such as a multi-part cam assembly. A furniture base can be quickly and easily detached from a particular seat box, and replaced by a different style of furniture base, by means of at least two cam or connector pieces having complimentary interlock mechanisms constructed and arranged to interlock one to another to form a cam or connector. A plurality of interlock mechanisms may be provided, as well as a plurality of positioning elements on respective cam pieces.

An one-piece corner connector for connecting two frame bars at right angles to one another includes a right-angle bracket having two angle legs, an intermediate plate, and two U-profile connecting pieces at right angles, having a middle leg and two side legs for insertion into the plug-in openings in the frame bars which are open at one end. The middle legs of the U-profile connecting pieces are formed on and run with their outer side parallel to the intermediate plate. The one outer side legs of the U-profile connecting pieces are each formed on one of the angle legs and run with their outer side parallel to the outer side of the angle leg. The other inner side legs of the U-profile connecting pieces are connected to one another by means of a wall element which is angled from the intermediate plate.

A child bassinet includes a support frame supporting an enclosure, and a playpen coupling mechanism provided on the support frame. The playpen coupling mechanism includes an adjustable catching part that is connected with the support frame and is engageable with a playpen for installing the child bassinet thereon. The catching part is movable relative to the support frame between a first and a second position of different elevations, and is further movable relative to the support frame between a locked state where the catching part engages with the support frame for locking the catching part in the first or second position, and an unlocked state where the catching part is disengaged from the support frame for movement of the catching part between the first and second position. The catching part is adjustable between the first and second position for installing the child bassinet on the playpen at different heights.
