Description

BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention

The present invention relates to a foldable table, more particularly, relates to a portable and foldable table leg frame, which is convenient to assemble for supporting a tabletop in a stabilized manner and easy to dismantle for a compact storage.

2. Description of Related Arts

Foldable tables are used and known for many purposes, especially in the routine practices. This is due to the fact that such kinds of table occupy less space and is easily to be carried or stored.

Commonly, the foldable table comprises a tabletop and a leg frame, wherein the tabletop is mounted horizontally on top of the leg frame, when the leg frame is unfolded. The leg frame is functioned as a supporting stand having pivotally mounted crossed legs for supporting the tabletop. Within the art, most leg frames of foldable table include X-shaped front and rear leg unit portions, and at least a linking rod interconnecting the front and rear leg unit portions. In other words, at least two pairs of legs pivoting in a scissor-like manner, so that the upper end of each leg unit portions could be used for mounting the tabletop thereon.

Or otherwise, the top ends of the upright front and rear leg unit portions are connected by horizontal braces and the braces are pivotally connected so that the tabletop connected to the top braces could be folded between horizontal and vertical positions.

In short, most of foldable tables are unexceptionally depending on the X-shaped leg frame structure to ensure the folding/unfolding function. Since the leg frames are pivotally connected together, the leg unit portion and linking rods should be of substantial thickness to ensure the durability. And the leg frame must be kept as a whole structure for supporting the tabletop, not for disassembly and portability in practical usage.

Furthermore, it is known in the art to employ bolts, screws or similar fasteners to connect together a plurality of table leg members or cross members to form a table leg frame. As a result, varying numbers and sizes of such bolts or fasteners would be used in an attempt to provide strength and stability to the leg frame for supporting the tabletop thereon. If such bolts are tightened excessively or in an improper sequence, one or more of the leg members of the leg frame may become uneven with respect to the others resulting in an unevenness of the tabletop.

Another popular table leg frame available in the market comprises an upright central column and a plurality of table legs pivotally and radially extended from the central column to form a plurality of footings for supporting the leg frame on a ground.

However, this kind of leg units has an obvious disadvantage. For example, in order to the fold the table legs, it is necessary that the legs move in an outward direction from the central column. This makes folding of the leg unit difficult when the foldable table is used in a small space, such as a camper.

What is more, when foldable tables are used outdoor, a supplemental parasol or umbrella is necessary. It is desirable to develop a portable and foldable leg frame for a foldable table to overcome above mentioned drawbacks of traditional foldable table frames, and provide a nesting spot for holding an umbrella.
