Description

[Detailed description of the invention] This invention relates to a foldable table that can reliably maintain both the folded state and the used state. To provide a folding table with a simple structure, in which the top plate does not unfold during movement, and mutual switching operations can be easily performed.

This invention will be explained below based on illustrated embodiments.

1 is a rectangular top plate, 2 is a pair of left and right square pipe inverted T-shaped support legs, and 3, 3 is an upward U-shaped support fixed to the upper end of each support leg 2, 2 is a metal fitting, the front side of which Both sides 4a, 4a of a square pipe support 4 attached to the lower surface of the top plate 1 are placed between the both side walls of one end extending to It is pivoted so that it can move freely down.

Reference numeral 7 denotes a locking piece fixed to the rear portion of the side portion 4a of the support structure 4 via a bolt 8a and a nut 8b, which projects toward the support leg 2 and has a downward hook portion 7a formed at its projecting end.

A locking pin 9a that engages with the downward hook portion 7a of the locking piece 7 is fixed to the upper end of the locking pin 9, sandwiched between two frames 9b and 9c, and the lower end is horizontally mounted on the supporting legs 2, 2. The arm is tiltably supported by a rotary shaft 10, which is tilted rearward, and is tilted forward by a coil spring 11 whose one end is pivotally connected to the support shaft 5 and the other end is fixed to the frame 9c. is biased to rotate in the direction.

Further, the frame 9b of the arm 9 is provided with an operating section 1 which is an extending piece that surrounds the front side of the supporting leg 2 and whose tip protrudes sideways in the shape of an ear.
2 are configured.

Reference numeral 13 denotes a shelf suspended below the top plate 1 at a predetermined interval, and a plurality of parallel round pipes 13 including the rotating shaft 10
a, 13a... and side frames 13b, 1 to which both ends are fixed
3b.

14 consists of a band plate having one end rotatably attached to the side frame 13b and the other end rotatably attached to the side portion 4a of the support structure 4 of the top plate 1 on the front side of the supporting leg 2. .

The inclined support arm is supported by the top plate 1 and the support leg 2 by the support arm 14 of the shelf 13 and the rotating shaft 10.

15 is a band-shaped left and right frame 15a. The chair tube is made up of a round pipe 15a and a round pipe 15b which is hung horizontally with both ends fixed to its rear end.
It is rotatably supported on.

The receiver 17 is fixed to the inner surface of the metal fitting 3, and the chair receiver is the part 15.
Angle material that receives the frame 15a, 18at18bt18
c is a washer, 19 is a camp made of resin molding that is fitted into the opening of the square pipe in the rear part 4b of the support structure 4 to improve its appearance, and 20, 20...- are attached to the bases of the supporting legs 2, 2. These are casters to make it easier to move the table.

In the folding table having the above configuration, in order to use the dot plate 1 in a horizontal position, the top plate 1 is raised horizontally and the locking pin 9a at the tip of the arm 9 is inserted into the hook portion γa of the locking piece 7. to engage.

In this state, if a force is applied to lower the top plate 1 in the direction of arrow t1 in FIG. 9
Since the spring 11 urges the arm 9 forward so that the arm 9 engages with the hook portion 7a and does not disengage, the above movement is prevented.

Therefore, the usage condition is maintained stably.

In this state, the shelf 13 is suspended parallel to the top plate 1 by the rotating shaft 10 and the support arm 14.

On the other hand, to fold it, push the operating section 12 toward the rear,
By tilting the arm 9 rearward against the biasing force of the spring 11, the locking pin 9a is released from the hook portion 7a of the locking piece 7.

As a result, the top plate 1 is lowered forward about the support shaft 5 as shown in FIG. 5, and at the same time, the shelf portion 13 is also folded and hangs down to become stable.

In this state, the chair support portion 15 becomes horizontally protruding as shown in FIG. 5, and a folding chair (as shown) can be inserted and held between the round pipe 15b and the back surface of the top plate 1. Become.

Furthermore, if there is no need to hold a folding chair (as shown in the illustration), the chair holder part 15 can be folded in the direction of arrow t3. It does not take up much space when not in use, is convenient to transport, and is safe as it reliably maintains its state both in use and folded.

In addition, mutual conversion between the two states is possible by a simple operation of slightly tilting the arm against the spring force, making it easy to handle, and the simple structure reduces the risk of failure and increases durability. Get rich.
