Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a foldable table that can be used for meetings, office work, study, meals, display of various items, work such as work, etc.

[0002]

[Prior art]

 To facilitate storage and storage, various types of tables that can be folded from the used state to the stored state have been proposed. Among them, it can be seen that the top plate can be changed from a horizontal use posture to a storage posture. Conventionally proposed tables of this kind are those in which the top plate can be folded in two at the center as shown in FIG. 10 (A), and the top plate can be folded at one end as shown in FIG. 10 (B). There are those which rotate around a portion or the like, and those which can expand and contract the top plate as shown in FIG. 10 (C).

In addition, as shown in FIG. 10D, for example, there is a structure in which the legs are folded.

[0004]

[Problems to be solved by the device]

 However, the above-described conventional folding table can only fold either the top plate or the legs, and cannot fold both of them at the same time into a compact accommodation posture. Also, in the case where the top plate is folded in two or the top plate can be expanded and contracted, when the top plate is expanded to a use state, a crease portion for folding in half or a divided groove for contraction or Many gaps and steps run, which is an obstacle and difficult to use. When rotating the top plate, if the top plate is long in the left and right directions, it is usually possible to rotate around the axis in the left-right longitudinal direction. Even if it is folded, the length in the longitudinal direction of the top plate remains as it is, which is an obstacle and still difficult to store and store.

Therefore, the present invention provides a folding table that can be folded compactly as a whole, as well as being able to change the top plate to a standing posture along the legs from the use state and folding the legs to a storage posture. The task is to do.

The folding mechanism 30 further includes a third link 33 rotatably connected to the top plate portion above the leg 3 at a portion 333 slightly closer to the other end 332 than the one end 331, and one end 341 being the first. And a fourth link 34 that is rotatably connected to the connection point of the second link and the other end 342 is rotatably connected to one end 331 of the third link, and one end 351 is the third. The other end 332 of the link 33 includes a fifth link 35 having the other end 352 rotatably connected to the vertical rod 302 of the leg 3.

Further, in the use state, the means 37 for connecting the vertical rod 302 of the leg 3 to the fourth link 34 intersecting with the vertical rod 302 and the interconnection point of the third and fifth links 33, 35 are connected to the top plate 1. And means 36. The connecting means 37 is for screwing the bolt 371 passed through the fourth link 34 to the vertical rod 302 of the leg 3. The means 37 is not always necessary. The connecting means 36 is composed of an interconnecting pin 361 of the third and fifth links 33, 35 and a pin support member 362 on the lower surface of the top plate. The support member 362 has an engaging recess 362a with which the pin 361 engages when the table is in use.

As shown in FIG. 9, one end portion 331 of the third link 33 is rotatably connected to the top plate 1, and the other end portion of the fourth link 34 is attached to a portion 334 displaced from the one end portion 331. It is also conceivable to rotatably connect the 342. In the table T3 described above, both legs 2 and 3 are spread laterally in a triangular shape when viewed from the front, and the tabletop 1 is placed in a horizontal lateral position (usually substantially horizontal) in a used state. For fixing and stabilizing the use state, the vertical rod 302 of the leg 3 of the folding mechanism 30 is connected to the fourth link 34 that intersects with the bolt 371 and the pin 361 is supported by the connecting means 36. The engaging recess 362a of the member 362 is engaged. Both legs 2 and 3 are placed on the floor, the ground, or the like.

When folding for accommodation, storage, transportation, etc., the bolt 371 of the connecting means 37 is removed and the pin 361 of the connecting means 36 is removed from the member recess 362 a. Next, the leg 3 is relatively pivoted toward the leg 2, and the relative movement of the top plate 1 along the leg 2 is performed by utilizing the interlocking operation of each link in the folding mechanism 30 accompanying this operation. Then, fold the whole table upright. The movement position of each link in this folding operation is shown by the thin chain line in FIG.
