DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 to 3 show an embodiment of the present invention. As shown in FIG. 2, a window 2 is provided on the sloped portion 1a above the front surface of the box body 1. A door 3 covering the window 2 is attached to the upper edge of the window 2 by a hinge 4 so as to be openable and closable.

The door 3 is provided with a see-through portion 3a made of transparent glass, transparent plastic or the like for allowing an operator to visually check the inside of the box 1. A handle 5 is attached to the lower edge of the door 3. The lower part 1b of the front surface of the box 1 is provided with a working opening 6 for a worker to put his / her hand on.

As shown in FIG. 2, a metal fitting 8 bent in a U shape for suspending the skirt 7 is attached along the inside of the upper edge of the working opening 6. This metal fitting 8
In addition, a V-shaped mounting plate 9 fixed to the upper end of the skirt 7 is removably suspended. The skirt 7 is provided with a large number of vertical slits 10 through which a worker can put his / her hand. An operator can work by putting both hands through the slits 10 and 10 at two places.

At the lower edge of the work opening 6, there is provided a base 11 on which a worker places his forearm when putting his / her hand in the box 1 and working. An elongated slot 12 for pulling out is provided below the working opening 6, and a tray 13 for receiving dust, abrasives, etc. falling down due to polishing work.
However, it can be pulled out horizontally from this long hole 12,
It is stored in the box 1.

A plate 14 having a large number of small holes is detachably attached to the upper portion of the tray 13. Therefore, large scraps and the like collect on the plate 14, and small dust and dirt collect on the tray 13 through the small holes. Therefore, the saucer 13
Can be pulled out and discarded. It should be noted that if water is put in the tray 13, dust or the like will settle in the water, which makes disposal even more convenient. A handle 15 is attached to the front surface of the tray 13.

As shown in FIGS. 2 and 3, above the receiving tray 13, inside the box body 1, support rails 20 and 21 are horizontally provided at the front and rear portions, respectively, and the left and right side plates 1 of the box body 1.
It is fixed between c and 1d. These two support rails 2
A support frame 23 having two rails 22a and 22b is attached so as to be slidable in the lateral direction along 0 and 21. A fastening screw (not shown) is provided on the support frame 23, and the support frame 23 can be fixed to a desired position in the left-right direction along the support rails 20 and 21 with the fastening screw.

A support base 25 is attached along the two rails 22a and 22b of the support frame 23 so as to be slidable in the front-rear direction. A tightening screw (not shown) is provided on the support base 25, and the support base 25 can be fixed to a desired position in the front-rear direction along the rails 22a and 22b with this tightening screw. The support 25 includes, for example, a working device 3 such as a polishing machine.
0 is detachably attached.

A rotary shaft 32 having a conical portion 32a at its tip is provided on both left and right sides of a motor 31 of the working device 30. An operator inserts a desired polishing disc 33 into the conical portion 32a and attaches the same to the slit 10 of the skirt 7.
It is possible to put both hands in and to carry out polishing work of a denture, for example. Therefore, two people can work simultaneously on the left and right of the motor 31. Further, the position of the support base 25 can be adjusted to the front, rear, left and right so that the operator can easily do it.

On the lower surface of the upper plate 1e of the box body 1, an upper end of a flexible support 40 which can be arbitrarily bent is fixed by a fixing tool 41. A shatterproof plate 41 is detachably attached to the lower end of the flexible support body 40, and the flexible support body 40 is freely bent so that dust and abrasives do not scatter to the transparent body 6 on the front surface. The shatterproof plate 42 can be located in front of the upper part of the.

At the rear portion of the box body 1, both ends of a shield plate 50 for receiving scattered dust and the like are provided on the left and right side plates 1c,
It is fixed to the mounting members 51 and 52 fixed to 1d. The shield plate 50 is inclined so that the lower part thereof approaches the rear plate 1f side of the box body 1, and spaces A and B are left and right above and below.

A suction port 53 is provided on the upper plate 1e of the box 1 behind the upper end of the shielding plate 50, and is connected to a hose 60 of a vacuum source (not shown) such as an electric vacuum cleaner. A cylindrical body 54 is provided so as to project upward. Therefore, dust or the like passes through the space A above the shield plate 50 and the space B below and is sucked from the suction port 53 to the external vacuum source.

An illumination lamp 55 such as a fluorescent lamp is provided on the lower surface of the upper plate 1e. An electrical equipment box 56 is provided inside the back plate 1f. 57 is a switch group of power supplies and others.

Due to such a structure, when two workers on the left and right sides from the front side of the box 1 put their both hands through the slit 10 of the skirt 7 and perform the polishing of the denture while visually seeing from the see-through body 3a. The scattering prevention plate 42 prevents dust and the like from scattering to the front transparent body 3a, and the dust and the like is sucked from the suction port 53 to the external vacuum source through the spaces A and B above and below the shielding plate 50. . At this time, air from the outside is introduced into the box body 1 through the slit 10 of the skirt 7. For heavy items such as dust, the lower tray 1
Since it falls to 3, the tray 13 can be pulled out and discarded.

The working device 30 may be provided with a cutting disc instead of the polishing disc and used for cutting. Further, the working device 30 can be removed from the mount 25 and replaced with a replacement device. Further, instead of polishing work so that smoke or the like at the time of soldering or welding work does not scatter to the surroundings, both hands can be put in the box body 1 to be used for soldering work or welding work.

[0026]

As described above, in the work box device of the present invention, a vacuum source such as an electric vacuum cleaner is connected to the vacuum suction port, and an operator manually inserts a vacuum source into the box through the slit of the skirt of the work opening. If you put the inside of the box and perform a work such as polishing on the work table while visually observing from the see-through part of the box, air will flow from the slit of the skirt to the vacuum suction port inside the box, so dust generated during work will be outside the box. It is sucked from the vacuum suction port without leaking to the inside of the worker, the worker's hands are not contaminated, and the environment inside the worker's room is not damaged.

Further, when the saucer is provided, dust and the like at the time of work is collected in the saucer at the lower part of the box body, so that the saucer can be pulled out and discarded. If a shielding plate is provided, dust during operation will hit the shielding plate and will be sucked into the vacuum suction port from the space above and below it, so the dust generated inside the box will be efficiently sucked into the suction port above and below the box. Is led. Further, since a large amount of abrasives and the like adhere to the shielding plate, it is possible to quickly clean the inside of the box by replacing or cleaning the shielding plate.
