【発明の詳細な説明】
従来の歯科用研磨ジスクは、研磨円盤をマンドレルの
先端に固定するために中心部に金属部材が位置していた
。DETAILED DESCRIPTION OF THE INVENTION Conventional dental polishing discs have a metal member located in the center to fix the polishing disc to the tip of the mandrel.
即わち、第１図示のものは、片面または両面に砥粒層を

研磨に使用するが、その際に中心に位置する金属部材が
被研磨物に接触して、深い傷を作つたり、着色条痕を作
つたりする。That is, in the first diagram, the center hole 2 of a disk 1 having an abrasive grain layer on one or both sides is reinforced with an eyelet 3, and the flange portion 6 and head portion 7 of a mandrel 5 having a split chimney 4 are formed. The eyelet 3 is snap-fitted into the neck 8 formed between. In addition, in the case shown in the second figure, the center of the disk 1 having the abrasive grain layer is clamped to the end face of a flange portion 6 provided at the tip of the mandrel 5 with a screw 9. What these devices have in common is that the flange of the mandrel is in contact with one side of the disk 1, and a metal member is exposed at the center of the opposite side. These polishing discs are used to polish teeth or their prosthetic materials, but during this process, the metal member located at the center may come into contact with the object being polished, causing deep scratches or colored streaks. do.
この発明は、このような金属部材が被研磨物に接触する
ことによる障害を除くことを目的とする。 この発明に
よる研磨ジスクは、研磨円盤の片面の中心にゴム或いは
軟質合成樹脂のブロックを有し、このブロックを介して
研磨円盤が回転軸に結合されている。The object of the present invention is to eliminate the trouble caused by such a metal member coming into contact with an object to be polished. The polishing disc according to the present invention has a block made of rubber or soft synthetic resin at the center of one side of the polishing disc, and the polishing disc is connected to a rotating shaft via this block.
そのために、研磨作業中に誤つて金属部材が被研磨物に
接触するおそれを除くことができるばかりでなく、研磨
円盤の片面はその中心部まで研磨作業に利用できるもの
である。 次に、この発明の実施例を第３図並びに第４
図によつて説明する。 １１は研磨円盤て、その片面１
１ａまたは両面１１ａ、ｌｌｂに砥粒層が形成されてい
る。Therefore, not only is it possible to eliminate the risk of the metal member accidentally coming into contact with the object to be polished during the polishing operation, but also one side of the polishing disk up to its center can be used for the polishing operation. Next, the embodiments of this invention are shown in FIGS. 3 and 4.
This will be explained using figures. 11 is a polishing disk, one side 1
An abrasive grain layer is formed on 1a or both surfaces 11a and llb.
その片面１１ｂの中心には、短円柱形の軟質塩化ビニー
ルブロック１２が、接着剤１３によつて接着されている
。 １４は回転軸、即わちマンドレルで、先端にフラン
ジ部１５と小径の頚部１６と偏平に膨大した頭部１７と
が形成されている。A short cylindrical soft vinyl chloride block 12 is adhered to the center of one side 11b with an adhesive 13. Reference numeral 14 denotes a rotating shaft, that is, a mandrel, and a flange portion 15, a small-diameter neck portion 16, and a flattened head portion 17 are formed at the tip.
前記のブロック１２は、頭部１７に対応した形状の内腔
１８と、頭部１６に対応して小径になされた開口１９と
、フランジ部１５に対応した凹所２０とを有する。使用
時には、ブロック１２の弾力により、回転軸頭部１７を
内腔１８へ押込んで、研磨円盤１１を回転軸端に取付け
る。 なお、回転軸１４の頚部１６及び頭部１７の部分
を螺子にして、ブロック１２に対応する螺孔を設け、両
者を螺合によつて結合してもよい。The block 12 has an inner cavity 18 having a shape corresponding to the head 17, an opening 19 having a small diameter corresponding to the head 16, and a recess 20 corresponding to the flange portion 15. In use, the elasticity of the block 12 pushes the rotary shaft head 17 into the inner cavity 18 and attaches the polishing disk 11 to the end of the rotary shaft. Note that the neck portion 16 and head portion 17 of the rotating shaft 14 may be screwed, a screw hole corresponding to the block 12 may be provided, and the two may be connected by screwing.
上述の実施例によつて明らかなように、この発明によ
るときは、研磨円盤１１の片面１１ａには全く金属部材
が存在しないので、被研磨物を傷つけるおそれがないば
かりでなく、その中心部分まで研磨に利用できる。また
別の片面１１ｂにも、金属部材が接近して位置していな
いので、被研磨部を傷つけるおそれが殆ど皆無に等しい
。よつて、極めて作業性が良い研磨ジスクを実現するこ
とができる。As is clear from the above-mentioned embodiments, according to the present invention, there is no metal member on one side 11a of the polishing disk 11, so there is not only no risk of damaging the object to be polished, but also the center part of the polishing disk 11. Can be used for polishing. Furthermore, since no metal members are located close to the other surface 11b, there is almost no risk of damaging the polished portion. Therefore, it is possible to realize a polishing disc with extremely good workability.
