A locking mechanism is provided to lock the upper vertical column and the lower vertical column to each other in the vicinity of the connecting pin, and the connecting pin is sufficiently radially inward from the imaginary straight line when folded and not in use. It is constructed so that it can be bent so that it can be positioned at

[Effect]

To pull out the held roll, one end of the held roll can be pulled and the roll can be pulled out continuously while rotating the turntable. By bending the vertical column and bringing the upper and lower annular frames close to each other, the outer frame can be compressed in the vertical direction to form a compact shape. On the other hand, by straightening the vertical column, the upper and lower annular frames can be separated from each other, and the outer frame can be expanded into a usable state.

〔Example〕

Embodiments of the present invention will be explained in detail based on the drawings.

In FIGS. 1 and 6, reference numeral 1 denotes a drawing device according to the present invention, and a rotary table 3 that holds a held roll 2 in which a flexible conduit 5, electric wires, cables, etc. are wound in a donut shape. is attached inside the outer frame 4 so as to be rotatable around a vertical axis.

The outer frame 4 is composed of an upper annular frame 6, a lower annular frame 7, and a plurality of vertical columns 8 that vertically connect these frames. In the illustrated example, the upper and lower annular frames 6 and 7 are circular. The vertical columns 8 are arranged at a plurality of locations on the circumference of the upper and lower annular frames 6 and 7, and at corresponding positions. Vertical pillar 8... is mounting piece 9
... are attached to the upper and lower annular frames 6 and 7, respectively.
Specifically, the mounting pieces 9 are fixed to the upper and lower annular frames 6 and 7 by welding or the like, and the pivot pins 10 attached to the mounting pieces 9 are used to connect both ends 1 of each vertical column 8.
1 and 11 are rotatably connected to each other.

Reference numeral 12 denotes a pivot shaft that rotatably supports the rotary table 3, and is fixed to support rods 13 provided integrally with the lower annular frame 7 so as to be in an upright state. Specifically, the support rods 13 are arranged radially, their inner diameter sides are interconnected via mounting plates 14, 14 (see FIG. 7), and their outer diameter sides are fixed to the lower annular frame 7. Ru.

The rotating table 3 has a plurality of radial arm portions 15...
and a holding column 16 that can be erected at an appropriate position of the radial arm portion 15, and support plates 17, 17 are provided on the inner diameter side of the radial arm portion 15.
It is fixed by welding etc. The rotary table 3 is rotatably supported by the outer frame 4 by fitting the pivot shaft 12 into a hole 27 formed in the center. Locking holes 18 are provided at appropriate intervals on the upper surface F of the radial arm portion 15.
...but a locking elongated hole 19 is attached to each side surface S, and by engaging the protruding pin 20 attached to the holding column 16 with the locking hole 18..., the radius of the holding column 16 is The directional position can be set as desired. A slide pin 21 provided on the holding column 16 is inserted into the locking elongated hole 19, and the slide pin 21 is inserted into the locking elongated hole 19.
The holding column 16 can be raised and lowered in the direction of arrow A in FIG. Although the inner diameter size of the center hole 28 of the held roll 2 varies, it can be accommodated by moving the holding columns 16 along the locking elongated holes 19. 29 in FIG. 7 is a sliding plate that reduces friction.

Thus, the vertical columns 8 can be freely bent and extended, so that the upper annular frame 6 and the lower annular frame 7 can be moved close to and separated from each other. Specifically, as shown in FIGS. 2 and 3, the vertical column 8 has an upper vertical column 8a and a lower vertical column 8b that can be freely bent to each other by a connecting pin 22 at the center in the vertical direction. In order to bring the upper and lower annular frames 6 and 7 into the unfolded and used state (extended state), it is only necessary to lift the upper annular frame 6.

The vertical columns 8... are connected by an imaginary straight line M connecting the pivot pins 10, 10 that pivotally connect the upper and lower vertical columns 8a, 8b having U-shaped cross sections, as shown in FIGS. 2 and 10. A connecting pin 22 pivotally connects the lower vertical column 8b so that the pin 22 is held in a radially outward position.
A locking hole 31 is provided near the locking hole 31.
A locking protrusion 32 that engages with the upper vertical column 8a is attached to the upper vertical column 8a.

At the same time, the lower end 23a of the back surface 23 of the upper vertical column 8a with the U-shaped cross section is connected to the (internal) lower vertical column 8b.
It is secured to the upper end 23b of the back surface 23 having a U-shaped cross section.

By the action of the locking mechanism 30 consisting of the mutual locking of the back surfaces 23 and 23 and the locking of the locking small hole 31 and the locking protrusion 32, the vertical column 8 is maintained in an extended state and the drawer is pulled out. During work, even if a force is suddenly applied from above or below, it will not bend in the radial direction and will not automatically become folded. In FIG. 1, reference numeral 24 denotes a spring-up prevention member provided to prevent the middle of the electrical conduit 5 from springing up during the drawing operation, and one end of which is supported by the upper annular frame 6. It is made possible to swing by.

Therefore, in order to fold the outer frame 4 into a folded and unused state, it is sufficient to simply bend the intermediate portions of the vertical columns 8 in the radial direction, as shown in FIG. Then, the mounting pieces 9, 9 attached to the upper and lower annular frames 6, 7, respectively, come into contact with each other, and the upper and lower annular frames 6, 7 assume a compact shape that is most compressed in the vertical direction, and are connected as shown in FIG. The position of the pin 22 is similar to that of the pivot pins 10 and 1.
It is located sufficiently in the radial direction than the imaginary straight line M connected between 0 and 0. In this case, the rotating table 3 has a flattened shape by folding down the holding columns 16 and is housed in a small gap between the upper and lower annular frames 6 and 7. Of course, in this case, as shown in FIG. 5, the turntable 3 can be taken out, folded separately, and stored before folding the outer frame 4.

Although the drawing operation can be performed without the spring-up prevention member 24, as shown in FIGS. 26 is also preferably provided so as to be elastically engaged with the upper annular frame 6.

Regarding the upper and lower annular frames 6 and 7, the overall planar shape may be a rectangle such as a square or a polygon such as a pentagon.

Although the inner diameter of the center hole 28 of the held roll 2 has various dimensions, the position of the holding column 16 in the radial direction with respect to the radial arm portion 15 of the rotary table 3 can be varied and set. Therefore, the inner diameter of the hole 28 can be easily and quickly adjusted.

The drawer device according to the present invention has the advantage of having a small number of parts and can be provided at low cost.

[Effect of idea]

As described above, the present invention has significant effects as described below.

By connecting the upper annular frame 6 and the lower annular frame 7 with vertical columns 8... and bending the vertical columns 8 radially inward,
In particular, the bulky outer frame 4 can be folded compactly by making it as short as a small child, making it more convenient to transport and store than the conventional folding drawer device.

The locking mechanism 3 in the unfolded use state (extended state)
Due to the function of 0, even if a force is suddenly applied from above or below, the outer frame 4 will not bend in the outer diameter direction and will not fall into a folded state without permission.When using multiple drawers at the same time, the outer frame 4... can be stacked up and down stably.

The structure is simplified by rotatably mounting the rotary table 3 that holds the held roll 2 inside the outer frame 4, and connecting the upper annular frame 6 and the lower annular frame 7 with vertical columns 8. The number of parts is small, making it lightweight and inexpensive to manufacture.

Furthermore, the outer frame 4 can be folded by simply bending the intermediate portions of the vertical columns 8 toward the inner diameter, and the upper annular frame 6 is lifted to bring the folded state into the unfolded state (extended state). It can be done very easily and quickly.
