関するものである。
[Detailed Description of the Invention] This invention relates to a holder for polishing a metal frame (hereinafter referred to as a crown) made of metal-baked porcelain.

保持具可動板の先端先細部に、鋳造したクラウンを挿着
してから基台の先端先細部の上面とでクラウンを挾持腰
クラウン外周面の鋳膚の研磨と湯口のスプルー線の撤去
に使用できるように構成されている。
Insert the cast crown into the tapered part of the movable plate of the holder, and then hold the crown with the upper surface of the tapered part of the base. Used for polishing the skin on the outer circumferential surface of the crown and removing the sprue line of the sprue. It is configured so that it can be done.

従来この種のクラウン外周面研磨とスプルー線撤去には
、保持具は用いられておらず、指先を道具として親指の
先端と人差指の先端との間にクラウンを差し入れて保持

状が異なり、一個として同一のものがなく、不等−であ
った。
Conventionally, no holder was used for this type of crown outer surface polishing and sprue line removal, and the crown was inserted and held between the tip of the thumb and index finger using the fingertip as a tool to perform polishing and removal. However, the sizes of crowns ranged from adult teeth to children's and infant teeth, and the sizes and shapes of crowns varied, and no two crowns were the same, making them unequal.

第8図に示すように、親指と人差指の先端部の接合面で
クラウンを挾んでも、小型の歯になるにしたがい、指先
よりクラウンが滑り落ち易く、ことに爪を整肌した後な
どは、一層滑り易くなるため常に落さず、ゆるまない様
にするため、指先に力が入って手先の疲れがあった。
As shown in Figure 8, even if you hold the crown between the joints of the tips of your thumb and index finger, as the teeth become smaller, the crown tends to slip off more easily than the fingertips, especially after the nails have been trimmed. As it became even more slippery, I had to constantly strain my fingertips to keep it from dropping and loosening, which caused my hands to get tired.

また、長時間に亘り硬質材のクラウンを研磨していると
、金属研磨時の加熱が指先に伝わり火傷がいつもたえず
、また、指先間より小さくとび出ているクラウンを研磨
するため、グラインダーが指先に当り易く、切り傷がた
えずあった。
In addition, if you grind the crowns of hard materials for a long time, the heat generated during metal grinding will be transmitted to your fingertips, causing constant burns.Also, because the grinder is polishing crowns that protrude smaller than between the fingertips, the grinder may touch your fingertips. It was easy to hit, and there were constant cuts.

ことにクラウンの研磨に要求されている精度が、以上の
ような指先の火傷・切り傷・疲れ等が原因し、クラウン

率な保持の欠点があった。
In particular, the accuracy required for crown polishing is difficult to hold due to the burns, cuts, and fatigue of the fingertips mentioned above, and this type of polishing and removal work requires inefficient holding. There was a drawback.

Above, the tapered part swings (seesaw) with the pressing action of the thumb.
Several examples of crown polishing holders have been described, but the present invention is not limited to the above-mentioned examples. Although not shown in the figure, other than the )-shaped configuration,
For example, there is a set of pliers that can be operated with the thumb and fingers to open and close the tapered part.

次に作用を説明すると 基台8の先端先細部3の下面指当部11を左手人差指2
2の側部に乗せてから親指21の腹部を可動板9の上面

Next, to explain the operation, press the bottom finger rest 11 of the tip end portion 3 of the base 8 with the left index finger 2.
2 and then determine the position where the abdomen of the thumb 21 is placed on the upper finger rest 10 of the movable plate 9.

まず、支点15上に親指の腹部を置き、可動板9の先端

First, place the abdomen of the thumb on the fulcrum 15, adjust it with the index finger and thumb so that the tapered part 2 of the movable plate 9 can swing up and down (seesaw), and move the thumb 21 to the left from the fulcrum 15. When you move your point of effort to and press the movable plate 9, the movable plate 9
The tapered portion 2 of the base and the tapered portion 3 of the base are in an open state.

Next, grasp the crown 12 with the fingers of your right hand, and
With the knob 13 on the lingual side surface 19 of the movable plate 9 facing downward, insert it until it reaches the end of the tapered part 2 of the movable plate 9.
3 is inserted into the through hole 7, the left thumb 21 moves past the fulcrum 15, and then presses the movable plate 9. The tapered parts 2 and 3 are closed, and the crown is closed. Since the inner peripheral surface of the crown 12 and the lingual surface 19 are firmly held between the base 8 and the movable plate 9, polishing of the outer peripheral surface, sprue wire, and knob 13 are possible regardless of the size of the crown. Although the removal work is not shown, it has a seesaw-like configuration in which the fingertips of the left hand, which is holding the base, and the little finger of the right hand, which is gripping the polisher, can lightly touch each other.
By polishing around the point of contact at the tip of the middle finger of the right hand, it is possible to completely prevent the tip of the polisher from wobbling, allowing for a higher level of polishing than ever before.

Next, the polished crown is moved to the left beyond the fulcrum by moving the thumb in the same way as the first movement, and then pressing the movable plate 9 leaves the tapered parts 2 and 3 of the tip open. Return to , remove the polished crown, and repeat the same process to polish the back of the crown and remove the sprue wire.

第8図に示す従来のクラウン保持方法では、クラウンが
小形になるにしたがって保持がしにくくなり、前記のよ
うに指先は研磨機によって切り傷とか火傷がたえずでき
ていたので、正確を要求されているクラウンの研磨・撤
去作業にはむかなかった。
With the conventional crown holding method shown in Figure 8, as the crown becomes smaller, it becomes difficult to hold it, and as mentioned above, the fingertips are constantly getting cuts and burns from the polishing machine, so precision is required. It was not suitable for crown polishing and removal work.

しかし、この考案に係る研磨用保持具では、クラウンを
可動板の先細部に挿着腰基台上に乗せて挾持するだけの
簡単な、片手指先の動作による構成としたので、つぎの
効果をあげることができる。
However, in the polishing holder according to this invention, the crown is simply inserted into the tapered part of the movable plate, placed on the waist base, and held by the fingertips of one hand, so that the following effects can be achieved. I can give it to you.

(1)支点を堺に親指を左右方向に位置移動できる簡単
な操作で、可動板の先細部が上下に開閉自在となるので
、クラウンの大きさは関係なく着脱が自在となり、かつ

(1) The tapered part of the movable plate can be opened and closed up and down with a simple operation that allows you to move your thumb from side to side using the fulcrum as the fulcrum, making it possible to attach and detach the crown regardless of its size. The contact surface is a rough surface or the through hole and crown holder are provided with a recess, so they can be securely seated and held.
It prevents slipping and wobbling after the crown is installed, and improves the polishing accuracy of the baked surfaces and tongue surfaces of thin-walled parts that require precision polishing.

(2) さらに、クラウンが研磨されて発生した加熱
でも、指に熱が直に伝導しない材料を用いたため、指の
火傷はなくなり、また、保持具を介して挾んでいるため
、研磨機による指の切り傷も防止できた。
(2) Furthermore, even if the crown is heated during polishing, the heat will not be directly conducted to the fingers, so there will be no burns on the fingers.Furthermore, since the crown is held between the holders, the fingers will not be exposed to the heat generated by the polishing machine. It was also possible to prevent cuts.

(3)なお、保持具は、手の中に入いる位の小型で軽量
なため、長時間の撤去作業を行っても指の疲れがなく、
能率があげられる。
(3) The holder is small and lightweight enough to fit in your hand, so your fingers won't get tired even during long removal work.
Increases efficiency.

(4)また、部品数の少ない揺動式(シーソー状)の構
