AI Technical Summary

Benefits of technology

The positioning mechanism described in the patent text is a simple yet effective way to support and stabilize a foldable shelving unit. It uses a rigid latch or hinge to connect to the structure, providing stability as it moves between different levels. The foldable shelves are made of cross-hinged U-shaped bars that can support the shelves and also connect to the rack, creating a stable structure. The upper bars are hinged to the ends of the lower bars, allowing for both vertical opening and folding. The positioning mechanism is easy to operate and provides reliable support and stability.

Problems solved by technology

Currently, there are multiple different models of foldable shelving racks, but most are difficult to open and unfold and they have poor stability.
However, it does not describe how the two sides of this rack are connected or how the separating boards fit into the structure.
Folding it would require every shoe frame to be turned over, and during the folding process the shoe frames would be hanging at one end, thereby posing a potential hazard.
Furthermore, the two ends of the folding frame rely on right-side hinges to secure the connection, thereby weakening the stability.

Embodiment Construction

)

[0049]Referring to FIGS. 1 to 4, the foldable shelving rack is composed of the folding rack (100) and shelf units (2). The folding rack (100) has multiple levels, with each level holing one shelf unit (2). There is also a narrow shelving unit (201) near the ground at the bottom of folding rack (100). The folding rack (100) can also be fitted with a working table top (202) to replace a shelving unit (2). This working table top can be set at a height suited to the comfort of any particular user.

[0050]As shown in FIG. 3, within the multilevel structure of folding rack (100), one of the shelf levels can be fitted with the working table top (202). Each level is formed by the hinging of a pair of U-shaped bars (1). The U-shaped bars (1) has a middle section (11) and two curved sections (12) set parallel to each other. The U-shaped bar (1) is then cross-hinged by the curved sections (12). Each level forms a separate stable unit. The curved sections (12) of the upper U-shaped bars (1) conn...

Abstract

A type of foldable shelving rack that includes a folding rack and shelf units. Each level of the folding rack is formed by the hinging together a pair of U-shaped bars. The end of the upper U-shaped bar is hinged to the lower U-shaped bar, thereby forming multiple shelves comprising the foldable shelving unit. A positioning mechanism is located on the opposing hinged ends of the quadrilateral structure; each shelf unit rests between the middle sections of the two U-shaped bars, thus forming a stable and integrated unit that can be folded up.

Description

CROSS REFERENCE TO PREVIOUS APPLICATION[0001]This application is a continuation in part of U.S. patent application Ser. No. 15 / 489,913, filed Apr. 18, 2017, which application is incorporated herein by reference.BACKGROUND OF THE INVENTIONField of the Invention[0002]This invention is to a type of foldable shelving rack, which is specifically has a strong stability while maintaining the ability to be folded vertically.Technical Background[0003]Currently, there are multiple different models of foldable shelving racks, but most are difficult to open and unfold and they have poor stability. For instance, Chinese Patent Publication Application No. 201520384604.0 consists of a folding book storage device, having separators, a rack and an armrest. It has multiple levels of separators, with both sides of each separating board being supported by crossing tubular rods making up the rack structure. This rack structure's crossing rods are connected by hinges, thus allowing the storage device to ...
