Description

Description: TECHNICAL FIELD [0001] The present invention relates to a table in which a rotary table is rotated around a vertical axis with respect to a fixed table and pulled out. The present invention relates to a technology that facilitates rotation and widely uses the space under a rotary table.

[Background Art] Conventionally, in a table in which a rotary table is rotated around a vertical axis with respect to a fixed table and is drawn out, two support legs 6 and 6 are provided on the rotary table 3 as shown in FIG. ,
The rotary table 3 is rotated about the vertical axis 5 and pulled out. However, in the case of hanging the two support legs 6 and 6 in this way, the rotary table 3 can be automatically rotated favorably when the floor surface is uneven. It is difficult, and since there are two support legs 6 and 6, there is a problem that the support legs 6 and 6 interfere and the space below the turntable 3 cannot be widely used.

[Object of the Invention] The present invention has been made in view of such problems,
It is an object of the present invention to provide a table which can be easily supported while stably supporting the rotary table without being caught, and in which the lower portion of the rotary table can be widely used.

DISCLOSURE OF THE INVENTION According to the table of the present invention, a top plate member 4 of a rotary table 3 is provided below a top plate 2 of a fixed table 1 so as to be horizontally rotatable around a vertical axis 5, and the top plate member 4 is farther away from the vertical axis 5. A support leg 6 is hung on a portion of the support leg 6, and a traveling tool 7 for traveling on the floor is provided at the lower end of the support leg 6, and the vertical axis 5 and the top plate member 4 apart from the support leg 6 are provided below the top plate 2 on the vertical axis. It is characterized in that it is hung and supported on the top plate 2 so as to rotate on an arc centered at 5, and the above-mentioned object is achieved by such a configuration. That is, the top plate member 4 of the rotary table 3 is suspended and supported by the top plate 2 so as to rotate on an arc centered on the vertical axis 5 below the top plate 2, thereby supporting the support legs 6 of the rotary table 3. By using only one support leg 6 as described above, smooth running can be performed even if the floor surface has irregularities, and the turntable 3 can be pulled out and stored easily, and It is also possible to avoid damaging the floor surface, and in addition, since there is only one support leg 6, the space below the rotary table 3 can be widely used.

Embodiments of the present invention will be described in detail below with reference to the drawings.

The fixed table 1 is configured such that a peripheral side wall 8 hangs from three sides of the top plate 2 and the front and lower sides are opened. Below a top plate 2 of the fixed table 1, a top plate member 4 of a rotary table 3 is pivotally mounted about a vertical axis 5 so as to be horizontally rotatable. A support leg 6 is hung on a portion of the top plate 4 that is farther away from the vertical axis 5, and a traveling tool 7 that travels to the floor surface at the lower end of the support leg 6.
The caster wheels 9 as an example are attached. As shown in FIG. 4, a traveling body 11 is attached to a portion of the top plate member 4 separated from the vertical axis 5 and the support leg 6 by a bolt 10. A nylon washer 12 is interposed between the traveling body 11 and the top plate member 4. An arcuate rail centered on the vertical axis 5 on the top plate 2 side
The traveling body 11 to which the 13 is attached has a columnar shape, and a thin annular body 14 is provided on the upper end thereof. In addition, a semi-annular stopper 15 shown in FIG. Then, the collar-shaped annular body 14 is inserted into the rail 13, and the rotary table 3 is suspended and supported on the top plate 2 so as to rotate on an arc centered on the vertical axis 5 below the top plate 2. The rotary table 3 can be pulled out from and stored in the fixed table 1.

In this way, the top plate member 4 portion of the rotary table 3 is suspended and supported on the top plate 2 so as to rotate on an arc centered on the vertical axis 5 below the top plate 2, thereby supporting the rotary table 3. Since the number of legs 6 is one and the number of support legs 6 is one as described above, smooth running can be performed even if there is unevenness on the floor surface, and the turntable 3 can be easily pulled out and stored. It is also possible to avoid scratching, and since there is only one support leg 6, the space below the turntable 3 can be used widely.

FIG. 7 shows the second embodiment, in which the operating tool 16 is attached to the traveling body 11.
The operation tool 16 is repulsed upward by a spring 17 and a ball caster 18 is provided on the upper end of the operation tool 16. Then, a positioning hole 19 is formed in a stopper 15 provided at the end of the rail 13, so that the ball caster 18 stops at the stopper 15 at the drawer end of the rotary table 3.
When the rotary table 3 is pulled out, the position of the drawn rotary table 3 is determined, and the ball caster 18 is inserted into the positioning hole 19 even if some load is applied to the side on which the rotary table 3 is stored. The insertion state of the rotary table 3 can be maintained by inserting the rotary table 3. Pull down the operating body 14 against the spring 17 with your fingers, pull out the ball caster 18 from the positioning hole 19,
After that, the rotary table 3 is stored in the fixed table 1. In this case, the top plate 2 of the fixed table 1 is formed with the concave groove 20, and the upper end portion of the operating body 14 and the ball caster 18 are allowed to migrate in the concave groove 20. The rail 13 may or may not be provided in the middle of pulling out and rotating the rotary table 3.

FIG. 9 shows a third embodiment, which is an annular body 14 and an operating tool 16.
And are screw-fitted and the height of the annular body 14 is changed and adjusted so that the support leg 6 fits closely to the floor surface.
After such height adjustment, the position is held by the set screw 21.

10 to 15 (a), (b) and (c) show the rotary table 3.
The top plate member 4 is pivotally supported on the vertical axis 5 so as to be pivotally supported. The L-shaped mounting bracket 23 is attached to the side plate 22 of the fixed table 1 with a screw. A thickness adjusting cylinder 26 as an example of the vertical axis 5 in which a female screw 25 is formed on the circumference.
Is fixed by screwing in the male screw 24, and the protective cylinders 28, 28 are attached to the upper and lower edges of the mounting hole 27 of the top plate member 4 of the rotary table 3.
, A pressing member 29 is screwed into and connected to the height adjusting cylinder 26, and the top plate member 4 is rotatably attached to the mounting member 23 via the nylon washers 12, 12. In such a case, the variation in the thickness of the top plate material 4 can be dealt with by adjusting the screwing depth of the pressing body 29. And the mounting bracket 23 is
As shown in Fig. 16, make the mounting hole 31 a long hole and
The mounting position of the support leg 6 can be changed up and down so that the support leg 6 can be aligned with the floor surface. A non-slip plate 30 is interposed between the mounting bracket 23 and the side plate 22.

The table A configured as above is shown in FIG. 17 (a).
(B) Used as in (c) and (d). FIG. 17 (f) shows a perspective view of an installation example.

Although the running tool 7 is a caster wheel in the embodiment, it may be in a sliding contact form in which it slides in contact with the floor surface instead of a rotating form like a wheel. It is possible.

[Effects of the Invention] In summary, according to the present invention, since the top plate material portion of the rotary table is hung and supported on the top plate so as to rotate on an arc centered on the vertical axis below the top plate, the rotary table is provided. The number of supporting legs can be one, and by thus using one supporting leg, smooth running can be performed even if there is unevenness on the floor surface, and the turntable can be pulled out and stored easily, and , It is also possible to avoid damaging the floor surface, and because there is only one support leg,
There is an advantage that the lower space of the rotary table can be widely used.
