Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust collection case for preventing scattering of dust generated during restoration, grinding and polishing of resin dentures and the like.

[0002]

2. Description of the Related Art Teeth play a very important role in the daily life of humans, and for example, teeth may be lost due to tooth decay or inflammation of the gingiva due to aging. . As described above, if the teeth are lost, the food may not be chewed during the meal to cause visceral diseases, and the lack of teeth in the conversation may make it impossible to produce a correct pronunciation, which may interfere with daily life. So, in the past, if you lost your teeth due to cavities or aging, create a denture,
It was set at the position of the corresponding tooth in the oral cavity. However, such a denture may have poor occlusal or need to be recreated due to factors such as deterioration and displacement of the gingiva.

Such a denture is manufactured in conformity with the oral cavity in consideration of the shape of the jaw and skeleton of an individual patient, but in the end, it is mounted on the patient and no biting or discomfort remains. As such, its shape needs to be finely adjusted. In such a case, dentures are produced on a model based on the reproduction of the oral cavity, for example, on a model of a working room that is exclusively used by a dental clinic or a technician, but the fine adjustment suitable for each patient It is carried out while being mounted on the patient in the vicinity of the patient and confirming that there is no discomfort by polishing or grinding the defective portion.

As described above, when finely adjusting the shape of a denture by polishing or grinding, a hand insertion port is provided on the left and right of a box of a predetermined size to prevent shavings from scattering, and a rubber material is attached to the insertion port. There is known a dust collection box in which shavings and the like inside the box do not scatter to the outside. Figure 11
FIG. 7 is an external perspective view of such a conventional denture polishing dust collecting box 50. In FIG. 11, 51 is a work case, 52 is a lid that is openably and closably attached to the upper edge of the back of the work case 51 by a hinge or the like, 53 is provided on the lid, and the inside of the work case 51 is seen through. Is a transparent window, 54 is a right hand insertion opening provided on the right side surface of the working case 51, 55 is rubber gloves provided on the right hand insertion opening 54, and 56 is a left side surface of the working case 51. The left hand insertion opening 57 is a rubber glove provided at the left hand insertion opening 56. Further, 58 is a dust suction hole provided at the back of the work case 51, and 59 is a dust suction hose attached to the dust suction hole for sucking shavings by a dust suction device (not shown).

That is, in the case of performing polishing and grinding work on a denture, etc., a denture requiring polishing and a polishing machine are placed in a work case 51 and the lid 52 is closed. Then, for example, put the left hand in the rubber gloves 57 and hold the denture, etc., and the right hand in the rubber gloves 5
6, while visually observing the inside of the case 51 through a see-through window 53 provided in the lid 52, a polishing machine is used to polish the artificial teeth. In that case, when a dust suction device (not shown) is operated, the shavings are sucked from the inside of the work case 51 to the outside through the dust suction hole 58 and the dust suction hose 59.

However, for elderly people who have difficulty in going to the dental clinic, a dentist or a dental technician must visit the patient and take a model of the oral cavity to produce a denture as a part of the visiting dental examination. Some things must happen. Also in this case, the production of dentures is performed in a dental clinic or a work room dedicated to the technician, but fine adjustment of the shape according to the patient needs to be performed in the vicinity of the patient. The denture made must be ground and polished. In such a case, the dust collection box as described above could not be carried around.

As described above, it is difficult to carry the dust collecting box conventionally used in a compact manner, and since it becomes a large scale to carry the dust collecting device, shavings such as resin, which is a material of the denture, are removed. For example, a household waste bag (made of polyethylene containing calcium carbonate) is used as a familiar scattering prevention tool so as not to scatter in the room. That is, a denture made on a model is mounted on a patient, and a part where the patient feels uncomfortable is ground or polished in this household garbage bag to create a denture suitable for the patient. When the grinding / polishing is completed, the shavings in the dust bag are sucked by a household vacuum cleaner or the like to prevent scattering to the patient's house.

[0008]

However, as described above, when the denture is ground / polished in a household garbage bag (made of polyethylene containing calcium carbonate, etc.),
The shavings scatter slightly inside the room, and when you try to absorb it with a household vacuum cleaner, the vacuum cleaner sucks the shavings together with the shavings, making it difficult to absorb only the shavings as you wish. Met. Further, even though it is a transparent bag, the flexible bag surface is diffused and the like is difficult to see, and the workability is poor.

The present invention has been made in view of the above conventional problems, and is particularly lightweight, small and foldable, which is easy to carry even when grinding or polishing a denture at the patient's home in a dental visit clinic. An object of the present invention is to provide a foldable dust collection case that facilitates suction and cleaning of shavings.

Then, similarly to the first embodiment, it is possible to assemble a dust collecting case capable of polishing and grinding artificial teeth and the like without scattering resin shavings into the air.

Next, a folding type dust collecting case 1 of the present invention will be described as a third embodiment with reference to FIG. The lower case 2 and the upper case 3 are commercially available B5 size documents having a width of 27 cm, a depth of 20.5, and a height of 1 cm, similar to those in the first and second embodiments. Since it was created using a case, the same reference numerals are given and the description thereof is omitted. In FIG. 4, 34a is a front upper plate, 34b is a front lower plate, and 35b.
Is a right side wall plate, 36 is a right hand insertion opening provided in the right side wall plate 35, 37 is a left side wall plate, and 38 is a left side wall plate 37.
The left-hand insertion opening 39 provided in the above is an attachment member for attaching the front plate 34, the right side wall plate 35, and the left side wall plate 36 to the lower case 2.

The front upper plate 34a is formed of a transparent synthetic resin plate or a glass plate (for example, an acrylic plate) in which static electricity is unlikely to occur, as in the first embodiment, and has a width 26c.
m, length 17.5 cm, and thickness 1-3 mm. The front upper plate 34a has a widthwise edge 34c.
Is rotatably attached to the inside of the front opening side 3b of the upper case 3 by the attaching member 39. Further, in the present embodiment, the front upper plate 34a is, for example, several cm below the other edge of the front upper plate 34a so as to be locked to the other edge 34d facing the one edge 34c of the front upper plate 34a. 34
Locking protrusions 34h are provided so as to protrude inward by about 5 mm to 1 cm at parallel positions inside a few cm (1 to 2 cm) from the edge of d.

The front lower plate 34b is formed of a transparent acrylic plate or the like like the front upper plate 34a, has a size substantially the same as the front upper plate 34a, and has one edge in the width direction thereof. 34e is rotatably attached to the inside of the front opening side 2b of the lower case 2 by the attaching member 39. That is, the other edge 34f of the front lower plate 34b is set inside the other edge 34f of the front lower plate 34b by the locking projection 34h provided on the other edge 34d facing the one edge 34c of the front upper plate 34a. Be locked. At this time, an operator can easily assemble the dust collecting case by holding a portion extending several centimeters from the edge of the other edge 34d below the front upper plate 34a.

In the present embodiment, the right side wall plate 35 is made of a transparent synthetic resin plate or a glass plate (for example, an acrylic plate) which does not easily generate static electricity like the front upper plate 34a and the lower front plate 34b. This is because the sides 35a and 35b contacting the lower case 2 and the upper case 3 are about 17.5 cm, and the side 35 contacting the front upper plate 34a and the front lower plate 34b.
c and 35d are approximately 10 cm. The front upper plate 34a and the front upper plate 34a are formed so that the angle θ does not exceed 90 degrees. Further, a right hand insertion opening 36 of about 10 cm is provided in the approximate center of the right side wall plate 35. The one side 35a located at the bottom is rotatably attached to the inside of the right opening side 2c of the lower case 2 by the attaching member 39. Then, by leaning the right side wall plate 35, the one side 35b on the back side is moved to the upper case 3c.

When the left side wall plate 37 is leaned against the inside of the front upper plate 34a and the front lower plate 34b together with 5, the foldable dust collecting case 1 can form a wide working space. Then, the right hand insertion opening 36 and the left hand insertion opening 38
Similarly to the first embodiment, by providing a color net sheet (scattering prevention material) not shown, it is possible to prevent resin scraps and the like in the work space from scattering outside the case. In this way, by forming the left and right side wall plates in a rhombus shape, the work space can be widely configured, and a person with a large hand can easily put his / her hand in it, and a large polishing machine is used. In this case, you will be able to work smoothly. At this time, in the right side wall plate 35 and the left side wall plate 37, one side 35b on the back side of the right side wall plate 35 is on the right side opening side 3c of the upper case 3 and the other side is on the back side of the left side wall plate 37. Since one side 37b is rotatably attached only to the left side opening 3d of the upper case 3, when the hand is inserted into the working space through the right hand insertion opening 36 and the left hand insertion opening 38, the right side wall plate 35 is formed. Since the left side wall plate 37 moves so as to be folded inward, locking grooves (not shown) are formed inside the front lower plate 34b in the vicinity of the left and right edges and parallel to the edges. The stop groove may prevent the right side wall plate 35 and the left side wall plate 37 from being folded inward during work. At this time, the locking groove (not shown) may be provided with two locking members in parallel with the edge to form the locking groove.

In the above embodiment, the front plate 34,
The right side wall plate 35 and the left side wall plate 37 have been described as being rotatably attached to the lower case 2 to be housed therein.
The front plate 34, the right side wall plate 35, and the left side wall plate 37 may be attached to either the upper case 3 or the lower case 2 without any particular limitation. When attached to the upper case 3, when the upper case 3 is opened from the lower case 2, the front plate 34, the right side wall plate 35, and the left side wall plate 37 hang downward, and the dust collecting case can be assembled with one touch.

Further, as shown in FIG. 5, if the front side of the side plate 35 is inclined so as to be positioned inside, even if the case has a large width (for example, A4 size document case), the work can be performed. A person can easily insert both hands into the case, which improves workability. FIG. 5 is a partial view showing an outline of the relevant portion of the fourth embodiment in which the front side of the left and right side plates 35 is narrowed inward.

Further, in the fourth embodiment, only the side plate 35 is tilted so that only the front side of the side plate 35 enters the inside, and the front upper plate 34a and the front lower plate 34b are left as they are. Although an excessive protrusion is left, the corners of the front upper plate 34a and the front lower plate 34b may be deleted as shown in FIG. 6 as the fifth embodiment. FIG. 6 is a partial view schematically showing the fifth embodiment in which the corner end portions of the front upper plate 34a and the front lower plate 34b are deleted.

In the fourth and fifth embodiments, in order to fix the side plate 35 at a predetermined position,
Providing a locking protrusion for locking the side plate 35 at a predetermined position of the lower case 2 or the upper case 3 facilitates the assembly of the case.

In the above embodiment, the resin dust after polishing and grinding of the denture is sucked with a household vacuum cleaner or washed with water, but the folding dust collecting case is used. The upper case 3 may be provided with a mounting port for mounting a suction nozzle of a dust suction device such as a vacuum cleaner so that the resin dust can be sucked while polishing and grinding (the mounting of the dust suction device will be described in detail later). . At that time, a drainboard or the like may be attached to the suction port so that the work position such as polishing is not directly sucked.
