Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) The present invention relates to a table on which an electric device or the like is placed on a top plate and an adjuster used for the table.

(Prior Art) Conventional desks, tables, and the like are mainly configured to be used individually, but when a large number of people use them simultaneously, such as a conference room, The top plates of some desks, tables, etc. may be used in close contact with each other.

FIG. 9 (a) is an explanatory view showing a case where the conventionally used tables are used in close contact with each other, FIG. 9 (b) is a sectional view of a leg portion, and FIG. 9 (c) is shown in FIG. It is an enlarged detailed view of the A part shown.

The tables 1 and 2 shown in the figure each include a top plate 3 and 4 made of plywood and the like, and a plurality of legs 5 and 6 which are made of aluminum alloy or the like for horizontally supporting the top plate 3 and each of the legs 5 and 5. An adjuster 7 for adjusting the height of the floors 6 and 6 in contact with the floor surface is attached in accordance with the unevenness of the floor surface.

Further, the internal configurations of the leg portions 5 and 6 are shown in FIGS.
As shown in FIG. 5, a plurality of ribs are combined to withstand a constant load, and the adjuster 7 is fitted in and attached to a rib 5a having a square shape in the central portion.

The illustrated adjuster 7 is a fitting member 7d made of synthetic resin.
And a height adjusting member 7e including a male screw portion 7b screwed into a female screw portion (not shown) formed at the center of the fitting member 7d and a contact portion 7a made of synthetic resin. is there.

(Problems to be solved by the invention) By the way, the top plate 3 of the table 1, 2 having the above-mentioned configuration
When the four are closely contacted as shown in FIG. 7A, the legs 5 and 6 are mounted on the back side by a distance C from the contact end surfaces 3a and 4a of the top plates 3 and 4, respectively. Therefore, the adjacent leg portions 5 and 6 are separated from each other by the distance 2C.

Therefore, when the top plates 3 and 4 of the adjacent tables 1 and 2 are used by being connected to each other, it is desirable to fix the adjacent leg parts 5 and 6 to each other. There is a problem that they cannot be connected because they are separated from each other.

In addition to documents, etc., electric appliances such as lighting fixtures, calculators, word processors, etc. that require a power source are placed on the tops 3 and 4, but these power cords are randomly wired to the outlet. In some cases, the other power cord was accidentally pulled out when the plug was inserted or removed.

Since the entire load from the leg portions 5 (6) is intensively borne by (indicated by d in the figure), the collar portion 7c is crushed over time and buried in the leg portions 5 and 6. Also had.

On the other hand, it is considered that the fitting member 7d itself may be replaced with a metal member, but in this case, the fitting tolerance between the fitting member 7d and the rib 5a must be taken into consideration, which makes the manufacturing process difficult. The problem arises that

The top plate is formed of plywood or the like, but this dimensional value tends to cause a dimensional error in the manufacturing process. By the way, there is a technique described in Japanese Utility Model Publication No. 62-11455 as a desk connecting device, but even with this technology, since a gap is formed between the legs of the adjacent desks, close coupling cannot be performed, There is a disadvantage that the mechanism needs to be devised and becomes complicated, which is not preferable.

Therefore, an object of the present invention is to provide a table in which tables can be easily connected to each other and which can be easily assembled, and an adjuster used for the table.
