A detachable shelf including four column assemblies, where each column assembly includes a plurality of columns distributed along a height direction; in each column assembly, adjacent columns are detachably connected; a plurality of support frames are disposed along the height direction among the four column assemblies; the support frame includes two mutually-parallel first cross beams and two mutually-parallel second cross beams; the front first cross beam is detachably connected to corresponding columns at front left and right ends and the rear first cross beam is detachably connected to corresponding columns at rear left and right ends; the left second cross beam is detachably connected to corresponding columns at left front and rear ends, and the right second cross beam is detachably connected to corresponding columns at right front and rear ends.

A shelf includes a bottom plate, a vertical plate, and a side plate. The bottom plate and the vertical plate are pivotally connected through a pivot mechanism and a first restricting mechanism that are disposed at a pivot joint of the bottom plate and the vertical plate. The pivot mechanism includes a rotating shaft disposed on the bottom plate and a first engaging hook disposed on the vertical plate. The first engaging hook is configured to catch the rotating shaft. The first restricting mechanism is configured to restrict a maximum unfolding angle of the bottom plate and the vertical plate. A second restricting mechanism is provided between the side plate and the vertical plate. The shelf simplifies installation steps and reduces installation and transportation costs.

A flexible shelving unit includes a support frame having at least one vertical guide rack, the guide rack including an elongated slot. The shelf unit is supported by the guide rack. The shelf unit includes a shelf plate framed by a front reinforcement portion and by at least one side reinforcement portion. The shelf unit when in a release position is moved to selected upward and downward locations by vertical displacement of at least one locating pin connected to and extending from the at least one side reinforcement portion which is positioned and sliding within the elongated slot. A flat end face of the at least one side reinforcement portion directly contacts a plate face of the at least one vertical guide rack with the at least one side reinforcement portion and the shelf plate in a horizontal position to frictionally retain the shelf unit in the horizontal position.

An adjustable bathroom handrail assembly is provided with a pair of elongate vertical handles with mounting hardware to mount to an upright support surface and spaced apart from the upright support surface. An adjustable horizontal bar extends between the pair of vertical handles, and a locking mechanism connects the at least one adjustable horizontal bar and one of the pair of elongate vertical handles. A locking mechanism is located at an intersection of the horizontal bar and the one of the elongate vertical handles. A method for installing and adjusting wall-mount hardware installs a pair of elongate vertical handles to an upright support surface. The ends of a horizontal bar are installed onto the pair of elongate vertical handles. A locking mechanism on the horizontal bar is disengaged to adjust the horizontal bar to a location along the pair of elongate vertical handles.

An height-adjustment apparatus for a structure (e.g., a workstation, a work table, shelf system and/or a rack system) is disclosed including a release mechanism, a pawl coupled to the release mechanism and a sleeve including a plurality of slots. The plurality of slots is configured to receive a locking portion of the pawl, the sleeve is configured to be coupled to a support element (e.g., a leg or post) of the structure and while the release mechanism is activated the locking portion is configured to disengage from one of the plurality of slots and a height of a surface of the structure is configured to be adjusted. The surface of the structure is coupled to the apparatus via an end cap adapter.

The present invention discloses a connecting structure, a connecting method and an article containing the connecting structure. The connecting structure includes a fastener, a first connecting member adjacent to the trailing end of the fastener and a second connecting member away from the trailing end of the fastener. The second connecting member is provided with a threaded connecting hole, which in the axial direction thereof is provided with thread matching with the form of thread of the fastener and having a central angle of at least 180 degrees. The first connecting member is provided with a connecting hole, and the fastener connects the two connecting members through the threaded connecting hole and the connecting hole. The connecting method achieves quick connecting with the connecting hole of the first connecting member by preloading the fastener to the threaded connecting hole, without being affected by the assembly space. The connecting structure and the connecting method can be used in a variety of articles. The thickness of the threaded connecting hole is equal to the pitch of the fastener. The form of thread of the threaded connecting hole is fitted with the thread of the fastener by only one turn, which during processing can be made directly in the form of stamping, resulting in a simple processing and improving the processing efficiency.

A cabinet system includes a frame at least partially defined by a plurality of vertical legs and a shelf defining a first plane and supported by the plurality of vertical legs. The vertical legs extend transverse to the first plane. A countertop is supported by the plurality of vertical legs. A body panel is coupled to the frame and has a plurality of apertures. A door is coupled to the frame and operable to selectively provide access to the shelf. The door has a plurality of apertures. Posts are coupled to the frame and extend transverse to the first plane. Each post of the plurality of posts is configured to extend through (i) an associated aperture of the plurality of apertures in the body panel to couple the body panel to the frame or through (ii) an associated aperture of the plurality of apertures in the door to couple the door to the frame.

Disclosed herein are various embodiments of a display unit with built-in, hollow vertical supports that are formed out of a single sheet of material. As one example, a display unit having a plurality of built-in, hollow vertical supports for supporting one or more shelves is provided.
