TECHNICAL FIELD OF THE INVENTION
The present invention relates to a table, and more particularly to a stack table that can be stacked with a small volume when not in use.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as tables for meetings and various meetings, there are tables that are taken out to a predetermined place and used when necessary.
[0003]
When this type of table is not in use, the legs are removed from the top plate when not in use, so that it can be stored in a warehouse or the like in a compact form when not in use. In the case of four legs, the legs can be folded so that the legs can be folded to have a compact form.
[0004]
However, as described above, attaching the legs during use and removing the legs when not in use requires an extremely troublesome operation, and is particularly difficult for a conference or meeting table because of its large number.
[0005]
Therefore, various tables have been conventionally proposed as tables which can be stacked in a small volume without removing or folding the legs.
[0006]
That is, as shown in the stacking state in FIG. 9A, the left and right pillars a, a can be freely turned in a vertical posture about the axis c with the table top plate b as the center and the grounding portions d of the left and right pillars a, a , And d are sequentially intertwined and stacked, or as shown in FIG. 9B, the table top plate b can be freely turned to a vertical posture about an axis c, and the left and right pillars a , A are formed in a “C” shape in a plan view, and the grounding portions d, d are sequentially inserted and inserted into a stack (see Patent Document 1). is there.
[0007]

[Problems to be solved by the invention]
However, according to the method shown in FIG. 9A, since the grounding portions d and d of the pillars a and a are overlapped in the horizontal direction and stacked, when a large number of tables are stacked, the entire table becomes oblique when viewed in plan. Therefore, there is a problem that the storage space cannot be used efficiently.
[0009]
According to the method shown in FIG. Since the grounding portions d and d of a have an eight-shaped shape, there is a sense of incongruity in the table design, which is not preferable.
[0010]
Neither of the above methods can be applied to a relatively small table that is set up with a single pedestal for meetings, and a large space is needed to accommodate many such tables. Or separate the table top and the pedestal from each other.
[0011]
In view of the above, an object of the present invention is to provide a stack table that can be stacked in a compact form without removing the table, even if the table has only one pillar. is there.
[0012]
[Means for Solving the Problems]
As a means for solving the above problems, the present invention provides a table supporting the center position of the table top on the upper end of one pillar, and the table top on the upper end of one pillar by turning support means to maintain the horizontal posture. It is rotatably supported so that it can take a vertical position, and four legs are provided at the lower end of the pedestal in an equiangular arrangement in the radial direction, and it is located on one surface side of the table top in the vertical position. The two legs are set at a height that allows them to overlap the two legs on the opposite side. When the table tops in the vertical position are stacked so that they overlap, the legs that are located before and after that It is characterized by being stacked on top of each other.
[0013]
As a result, even if the table supports the table top with one pillar, it can be stacked as a minimum-capacity form, and the stacking state can be neatly arranged without bending when stacking. Can be used effectively.
[0014]
The rotation support means includes a pivot at the upper end of the pedestal that rotatably supports the center position of the table top from a horizontal position to a vertical position, and a locking rod provided on the lower surface of the table top so as to be switchable. A locking claw provided on the supporting portion and provided on the locking rod engages when the table top plate is turned horizontally and vertically, and is used for a horizontal posture and a vertical posture for restraining the table top plate at that position. And a projection provided on the support and supporting the lower surface of the table top when the table is turned horizontally.
[0015]
With this configuration, the posture of the table top can be changed only by operating the locking rod, which is particularly effective in the case of a small table for meetings where the user frequently takes out and uses the table.
