Description

Multi-purpose furniture assembly with safety features

The present invention relates to furniture. More specifically, the present invention relates to a knock-down lay flat furniture kit that can achieve different purposes through additional panels of different shapes.

Furniture can be defined as movable objects intended to support various human activities such as sitting, eating and sleeping. Furniture is also used to fix objects at a convenient height for storing objects or objects. Since most people are living in smaller spaces in the modern era, every piece of furniture needs to be made to serve multiple functions. The idea of ‘multi-purpose’ in pursuit of a smaller life goes a long way. When possessions perform more than one function, people may need less of them. In modern homes, multipurpose furniture saves space and allows people to choose smaller, more efficient living quarters. Multipurpose furniture, also known as modular furniture, can expand or contract as needed, can serve two purposes at once, or can be seamlessly converted from one function to another.

In one example shown in patent document US3556586A, multifunctional furniture, especially children's furniture, is formed from a monolithic hollow-walled molding of hard plastic material, operating as an upright chair, rocking chair, desk and table depending on the selective arrangement of the articles.

Figures 1-2 show diagrams of the assembled layflat furniture kit along with its accessories. The furniture kit includes a substantially rectangular backboard (100) and a pair of substantially rectangular metal side members (200) formed by ladder-shaped frames that are hinged to vertical edges of the backboard (100) and can be folded into two positions. It has a basic unit including, in one of the two positions, the side member 200 lies flat on the backboard 100, and in the other, the side member 200 extends perpendicular to the backboard 100. The side members 200, 210 further include means for limiting the splay of the side panels so that the kit can remain upright even before attaching additional panels. Preferably, the limiting means may not be limited to additional bars added to the ladder-like frames of the side members 200, 210, stoppers or ridges added to the ends of the backboards 100, 110. The backboard 100 includes a pair of hinged panels that can be folded along a vertical axis in a undulating manner. The kit can also be extended horizontally by attaching another backboard 110 with one side member 210 to the main backboard 100 by connecting means. In addition, as shown in FIGS. 3 and 4, the backboard 100 includes hooks 222 for attaching the wire mesh frame 220 so that the wire mesh frame 220 can extend vertically from the backboard 100. do. Additionally, the wire mesh frame 220 is provided with additional hooks 221 hanging on the backboard 100 for reinforcement.

The kit is such that the side member 200 is attached to the side member 200 by a clip member 400 that closely fits the rungs and side portions of the side member 200, which should include a ladder-like member having both horizontal and inclined rungs. Includes additional panels. Additional panels in the kit may be of different shapes, including but not limited to drawers 320, shelves, cabinets 370, folding tables 330, and chairs. In the first example shown in Figure 5, where the additional panel is in the form of a drawer 320, the drawer 320 has two pairs of clips 400 mounted in different directions on the inside of the drawer 320, and thus the drawer ( 320) can slide along the rungs to the maximum permissible limit. The change in clip direction not only ensures that the drawer 320 is attached to the crossbar, but also acts as a grip channel to allow the sliding ability of the drawer 320.

In the second example shown in Figure 6, where the additional panel is in the form of a folding table 330, the folding table 330 is a two-part folding table top with clips attached on one side 332 and the other side of the table top. Includes a folding leg 311. The table 330 has a standing arrangement and a compact arrangement. In a standing arrangement, the table top lies flat in a substantially horizontal position and the legs are flipped outward to a substantially vertical position to support the table top. In a compact arrangement, the first section of the table top is rotated downward to a position perpendicular to the second section 332 of the table top and the legs are flipped inward to a position parallel to the first section. The height of the table corresponds to the length of the folding leg 331, and different heights can achieve different purposes. For example, a tall table may function as a bar table, while a shorter folding table 330 may function as a work desk.

A second embodiment of the clip member 400 shown in FIGS. 11A and 11B is a beam structure 405 with each free end having a “U” shaped hook 402 for attachment to a crosspiece of the side member frame. The beam structure also has a pair of protrusions 406 that can mate with the indentations of the additional panel 350.

A third embodiment of the clip member shown in Figure 12 is each in the form of a grooved wheel 321, where the crosspiece is seated within the grooved area of the wheel. This embodiment can be applied to additional panels in the form of drawers 320 to provide better sliding of the drawers with reduced friction.

In some countries where earthquakes occur frequently, furniture may include anti-seismic features, as shown in Figures 11 through 13. In one of the examples, the clip member 400 further includes a support beam structure 405 that connects both sides of the clip member with fixing means to prevent the clip 400 from being separated from the crosspiece by external force. The beam also includes a pair of fastening means 406, such as roller catches, for fastening additional panels 350. In another example, a safety device may be applied to the grooved wheels 321 of the drawer 320, whereby reinforcement panels 322 are added next to the grooved wheels 321 to provide additional support to the drawer 320. provides. Additionally, the legs of the side members 200 have feet 201 that can be enlarged in size to improve the stability of the furniture.
