JPS5839696Y2 - Housing for dental laboratory dust collection work - Google Patents

Description

[Detailed Description of the Invention] This invention relates to a housing for dust collection work in a dental laboratory for rationally suctioning and removing dust generated when cutting and polishing dentures, tooth mold plaster, etc.

Conventionally, when dentists or dental technicians use sand pieces to polish or cut dentures, etc. in a treatment room or laboratory, cutting chips, cutting powder, and polishing powder are scattered inside the room, or This was not favorable from an environmental hygiene point of view, as dust was floating in the air.

In addition, there is a risk that the cutting chips, cutting dust, etc. may hit the eyes or face of the worker, and there are also disadvantages such as dust adhering to clothing, etc.

This idea was devised to eliminate the above-mentioned drawbacks, and its purpose is to completely confine the cutting chips and cutting powder that fly away during grinding work into a narrow working space, thereby reducing indoor air pollution. There is no contamination caused by grinding work, and there is no danger of the worker's face or eyes being hit. Furthermore, it is hygienic as it does not stain clothing at all, and it greatly improves dust absorption efficiency. By effectively utilizing light from outside, there is no need to install lighting equipment, regardless of precision work.
It is an object of the present invention to generally provide a casing for dust collection work in a dental laboratory, which reduces work noise and allows grinding work to be carried out smoothly and efficiently.

An embodiment of this invention will be described below with reference to the drawings.

Reference numeral 1 designates a housing, the entire side wall 1b and ceiling 1c excluding the bottom surface 1a being made of a transparent material subjected to antistatic treatment.

The side walls 1bi and the ceiling part 1c are made of synthetic resin plates such as transparent acrylic plates.

The side wall 1b and ceiling portion 1c are subjected to antistatic treatment.

This prevents dust from adhering to the inner surface of the casing 1, allows the inside to be seen through from the outside at all times, and allows light from the outside to be effectively transmitted into the casing, making it possible to maintain the casing even during precision work such as grinding work. This eliminates the need to install lighting equipment within the interior of the building.

The size of the housing 1 is such that it can be used for grinding with one hand.
There should be enough space to hold the denture, etc., in one hand and work comfortably while holding the denture, etc., in the other hand.

2 is a suction port for dust collection installed inside the housing 1.The suction port is installed in the back left corner at a predetermined height from the bottom surface 1a, considering workability and suction effect. location is most favorable.

Reference numeral 3 denotes two through holes drilled at a predetermined distance in the side wall 1b of the square body 1, into which hands are inserted through the respective holes X.

The holes 3 are drilled at the front 1b' and right side 1 of the side wall 1b.
When installed on f (see Figure 1), both left and right side faces 1
tr, 1b' and two cases are provided on the front surface 1b'.

However, when considering the efficiency of the grinding work within the housing 1, it is preferable to provide one each on the front surface 1b' and the side surface 1d'.

The shape of this through hole 3 is usually circular, and the size of the through hole should be such that dust does not scatter to the outside, and one hand button and arm should be able to comfortably hold the hand button and arm in consideration of ease of work such as inserting the handpiece. It should be enough to be inserted.

4 is an elastic material with slits provided around the periphery of each through hole 3 in order to prevent dust from scattering to the outside of the housing 1. Usually, a rubber plate is cut into a circle larger than the through hole, and the center part is cut out. This can be obtained by hollowing out and attaching slits 4a at predetermined intervals in the radial direction to the inner peripheral edge of the through hole 3.

The purpose of providing the elastic material 4 with slits around the periphery of the through hole 3 is to prevent dust from scattering to the outside of the casing 1 as described above, as well as to prevent outside air from entering the casing through cracks and gaps such as slits. 1. To improve dust collection efficiency by making it possible for the worker to insert and remove the hand or arm of the worker. This is because the elastic material is used to relieve the force from the thickness of the through-hole portion of the housing 1 so that the arm does not become painful.

Since this idea has the above structure, in practical use,
The proposed case should be placed on a workbench or desk, or incorporated into a dedicated dental laboratory dust collector (first
(see figure).

Then, connect the suction port 2 for dust collection to the suction side of a household vacuum cleaner or a special dust collector for dental use, and turn the dust collector etc.
Set it to N so that it can be aspirated.

On the other hand, hold the grinding band piece A in your right hand, hold a denture, etc. in your left hand, insert the right button and its arm through the through hole 3 on the right side 1C, and insert your left hand through the through hole 3 on the front side 1b'. After putting both hands into the housing 1, the band piece A is rotated and the cutting operation is performed while looking through the band piece A from the outside.

During this grinding operation, scattered chips and floating dust within the housing 1 are effectively suctioned and removed through the suction ports 3.

After the work is finished, the cutting chips and dust remaining on the bottom surface 1a of the housing 1 can be removed by suction by connecting a cleaning hose C to the suction port 3 (see FIG. 3).

As you can see from the above explanation, this design completely confines cutting chips and floating dust that fly away during grinding work within the housing, so that the air and floors in the treatment room and laboratory room are not affected by the grinding work. It is preferable in terms of environmental hygiene because it does not become polluted.

In addition, you can work safely because cutting chips and dust never hit your eyes or face.

Moreover, it is always hygienic because no dust or the like will adhere to clothing.

Furthermore, the casing completely surrounds the grinding work space, and an elastic material with slits is interposed in the gap between the periphery of the X-hole and the arm, allowing an appropriate amount of outside air to enter through the gap between the slits, etc. Together, the dust suction efficiency can be further increased.

In addition, the entire side wall button and ceiling, excluding the bottom, are made of transparent material that has been treated with anti-static treatment, so dust does not adhere to the inside of the case and it is easy to see through from all angles. Not only is it possible to carry out the work, but it also allows outside light to pass through the entire area around the side walls and the ceiling, providing excellent lighting, and does not require any lighting equipment even when performing precision work. be.

Another advantage of this invention is that since the grinding work is carried out inside the housing, there is less noise and the psychological discomfort caused to the operator's button, patient, etc. can be alleviated.

In addition, by providing an elastic material with slits around the periphery of the hole, not only is it extremely smooth to put in and take out grinding beads, etc., but even if your arm hits the hole, the elastic material has a moderate cushioning effect, making it easy for your arm to slide in and out. It is painless and has excellent work efficiency.
