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.

A travel bag assembly that utilizes a bag construct with a top surface. A retractable pull handle is provided. A depression is formed in the top surface of the bag construct. A support platform is provided that either directly fits into the depression or can be folded to fit in the depression. The support platform is connected to the bag construct by at least one adjustable shaft. The adjustable shaft enables the support platform to be selectively adjusted in elevation throughout a range above top surface of the bag construct without effecting the retractable pull handle.

A gravity-lock, height-adjustable shelving, object support and hanging system which, in a preferred embodiment, comprises: a. at least one rod for substantially vertical installation, said rod having an outer diameter D; b. at least one slider comprising a bore therethrough, said bore comprising an inner diameter slightly greater than D, such that said bore through said slider accommodates passage of said rod through said slider; and c. at least one appendage attached or attachable to said slider, wherein said appendage extends substantially horizontally away from the point proximal the point of attachment to said slider to a distal point of said appendage.

Methods of making and using the apparatus, device and system according to the invention are likewise disclosed, and those skilled in the art, based on this disclosure, will appreciate that equivalents, permutations and combinations of the elements described herein to compose this invention may be made without departing from the core of the invention disclosed herein.

A supinely reading stand which barely blocks the text of the book, barely interferes with the sight of the eyes, and is more simply constructed, easy in assembly and lower-cost. The supinely reading stand comprises a book-supporting structure. The book-supporting structure comprises a four-sided frame and at least one tension-resistant thin line distributed in the inner area of the four-sided frame. The four-sided frame includes first opposite sides and second opposite sides. The tension-resistant thin line(s) is/are connected to the first opposite sides of the four-sided frame in tension state.

A combinative shelving unit includes two stand assemblies and a load tray. The two stand assemblies are arranged parallel to each other. Each stand assembly includes a pair of posts and a transverse link connected between the pair of posts. Each transverse link has a first assembling portion and a second assembling portion. One side of the load tray has a connecting portion and another side thereof has a second connecting portion. The first connecting portion and the second connecting portion are staggered in position. The first connecting portion engages with the first assembling portion of one of the transverse links, and the second connecting portion engages with the second assembling portion of another one of the transverse links.

A table has a tabletop, a vertical support, and a mounting frame disposed at a top end of the vertical support and attached to the tabletop. The mounting frame includes a fixing base, a rotating frame rotatably connected to the fixing base, and a rotating handle assembly rotatably connected to the rotating frame. The rotating frame is operable to rotate between a horizontal position and a vertical position. The rotating handle assembly includes an abutting block that engages the lower embedding notch in the fixing base when the rotating frame is in the horizontal position. The rotating handle assembly has a lower edge that engages the upper embedding notch in the fixing base when the rotating frame is in the vertical position. A handle, which extends outwardly from the rotating handle assembly, is configured to be operated by a user to move the rotating frame between the vertical position and the horizontal position.

A height adjustment mechanism for an adjustable height table includes an outer sleeve, an inner sleeve, a plug, and a locking mechanism. The outer sleeve is disposed outside the inner sleeve, and the outer sleeve and the inner sleeve are slidable relative to each other. The plug is disposed outside the inner sleeve, and is slidably connected to the inner sleeve. The plug is disposed at an upper end of the outer sleeve, and an outer wall of the plug includes a pressing portion. The locking mechanism operates to push the pressing portion tightly against an outer wall of the inner sleeve to increase the friction between the plug and the inner sleeve, so that the plug and the inner sleeve are relatively fixed.

A lifting desk is related to fields of lifting desks. The lifting desk includes a drive device, a gearbox, a desktop, a crossbeam, and a lifting column, the crossbeam being connected to the desktop, the lifting column being connected to the crossbeam, the gearbox including a gear assembly, the drive device being in driving engagement with the gear assembly, the gear assembly being in driving engagement with the lifting column; the lifting desk further includes a retaining plate, the retaining plate being securely connected to the desktop, the gearbox being connected to the retaining plate. The desk offers an advantage that the structure disclosed may enhance assembly precision of the lifting desk and enables lifting control of the desktop.
