FOLDABLE TABLE

Abstract

A foldable table includes: a tabletop; and left and right leg units, each of which includes a pivot joint and first and second supporting legs. The second S supporting leg has a top end pivoted to the tabletop. The first supporting leg has first and second segments. The first segment is pivoted to the second supporting leg and has an upper end pivoted to the pivot joint. The second segment has a first end pivoted to the pivot joint, and a second end pivoted to the tabletop. The first and second supporting legs are foldable relative to each other from a non-folded position, in which the first and second segments are aligned along an axis, and in which the first segment of the first supporting leg crosses the second supporting leg, to a folded position, in which the first segment of the first supporting leg is substantially parallel to the second supporting leg.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a foldable table, more particularly to a foldable table including a pair of first supporting legs, each of which has first and second segments pivoted to a pivot joint.

2. Description of the Related Art

FIG. 1 illustrates a conventional foldable table 1 that includes left and right leg units 11 and a tabletop 12 mounted pivotally on top ends of the left and right leg units 11. Each of the left and right leg units 11 includes first and second supporting legs 111, 112 pivoted to each other, and a pivot plate 13 pivoted to a top end of the first supporting leg 111. A U-shaped support rod 114 is secured to the pivot plates 113 of the left and right leg units 11, and is pivoted to the tabletop 12.

The aforesaid conventional foldable table 1 is disadvantageous in that the size of the table 1 is still relatively large when folded due to the presence of the U-shaped support rod 14.

SUMMARY OF THE INVENTION

Therefore, the object of the present invention is to provide a foldable table that can overcome the above drawback associated with the prior art.

Accordingly, a foldable table of this invention comprises: a tabletop; and left and right leg units, each of which includes a pivot joint and first and second supporting legs. The second supporting leg has top and bottom ends and a middle portion extending between the top and bottom ends of the second supporting leg. The top end of the second supporting leg is pivoted to the tabletop. The first supporting leg has first and second segments. The first segment is pivoted to the middle portion of the second supporting leg, and has an upper end pivoted to the pivot joint. The second segment has a first end disposed above the upper end of the first segment and pivoted to the pivot joint, and a second end pivoted to the tabletop. The first and second supporting legs are foldable relative to each other from a non-folded position, in which the first and second segments are aligned along an axis, in which the second end of the second segment is disposed above the upper end of the first segment, and in which the first segment of the first supporting leg crosses the second supporting leg, to a folded position, in which the first segment of the first supporting leg is substantially parallel to the second supporting leg and in which the second end of the second segment is disposed below the upper end of the first segment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 to 4, the preferred embodiment of a foldable table according to the present invention is shown to include: a tabletop 5; and left and right leg units 2, each of which includes a pivot joint 23 and first and second supporting legs 21, 22. The second supporting leg 22 has top and bottom ends 221, 222 and a middle portion 223 extending between the top and bottom ends 221, 222 of the second supporting leg 22. The top end 221 of the second supporting leg 22 is pivoted to the tabletop 5 through a pivot plate 54. The first supporting leg 21 has first and second segments 211, 212. The first segment 211 is pivoted to the middle portion 223 of the second supporting leg 22, and has an upper end 2111 pivoted to the pivot joint 23 through a first pivot pin 233. The second segment 212 has a first end 2121 disposed above the upper end 2111 of the first segment 211 and pivoted to the pivot joint 23 through a second pivot pin 234, and a second end 2122 pivoted to the tabletop 5. The first and second supporting legs 21, 22 are foldable relative to each other from a non-folded position (FIG. 3), in which the first and second segments 211, 212 are aligned along an axis (L), in which the second end 2122 of the second segment 212 is disposed above the upper end 2111 of the first segment 211, and in which the first segment 211 of the first supporting leg 21 crosses the second supporting leg 22, to a folded position (FIG. 6), in which the first segment 211 of the first supporting leg 21 is substantially parallel to the second supporting leg 22 and in which the second end 2122 of the second segment 212 is disposed below the upper end 2111 of the first segment 211.

In this embodiment, the pivot joint 23 is in the form of a U-shaped plate, and includes a middle portion 232, and two arm portions 231. The first and second pivot pins 233, 234 extend through the arm portions 231 of the pivot joint 23.

A pivot shaft 3 extends through the middle portions 223 of the second supporting legs 22 and the first segments 211 of the first supporting legs 21 of the left and right leg units 2.

A first stretcher 4 interconnects the first segments 211 of the first supporting legs 21 of the left and right leg units 2. A second stretcher 6 interconnects the second supporting legs 22 of the left and right leg units 2.

Referring to FIGS. 5 and 6, during a folding operation, one end of the table 5 that is distal from the second end 2122 of the second segment 212 of the first supporting leg 21 can be lifted so as to move simultaneously the second supporting leg 22 toward the first segment 211 of the first supporting leg 21 and the second end 2122 of the second segment 212 toward the first segment 211.

With the arrangement of the first and second segments 211, 212 of the first supporting leg 21 and the pivot joint 23, the aforesaid drawback associated with the prior art can be mitigated.

While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
