A pair of arms that can slide along both sides of the mounting body are provided at both ends of the shaft, and the tips of both arms are joined and bent into an L shape. Since the hooking portion that can be crimped and locked over the slot from the locking projection is formed, the fixing and opening operation of the arch wire can be performed reliably and easily without using the ligature wire. Therefore, orthodontic work can be performed smoothly.
Thus, the archwire in the slot is strongly pressed by the tip portion of the elastic lock member with the hooking portion of the lock member being crimped and locked to the locking projection. Even if a tensile force is applied to the archwire, there is no risk that the bracket will come off from the flood, and the correction work can be performed with peace of mind.
Further, since the structure is simple and easy to manufacture, there is an advantage that the cost can be reduced.

また、請求項2に記載したように、前記スロットをベース面に対して所要角度傾斜させて、その開口面がフック側を向くように形成すると共に、ロック部材の引掛け部の後側部が係止突部の外側に当接できるように屈曲したブラケットは、特に前歯や犬歯の歯列矯正に用いて好適であり、アーチワイヤを適正位置に確実に止着できると共にその作業も容易である。   According to a second aspect of the present invention, the slot is inclined at a required angle with respect to the base surface so that the opening surface faces the hook side, and the rear side portion of the hooking portion of the lock member is The bracket bent so as to be able to come into contact with the outside of the locking projection is particularly suitable for orthodontic correction of the front teeth and canines, and can securely fix the archwire in an appropriate position and the work is also easy. .

次に添付図面に従って本考案の実施例を説明する。本実施例のブラケットは、特に小臼歯等の歯列矯正に用いるものである。
図1乃至図5において、1はブラケット本体であって、歯に止着する平たいベース2上に取付体3を立設してある。
前記取付体3は、その上側中央部には、近遠心方向に、アーチワイヤWを収容するスロット4を設けてある。
また、前記スロット4の歯茎側外側部にはスロット4に沿ってT形状のフック5を突設してあり、スロット4の歯先側外側部にはフック5と反対向きにタイウイング6を突設すると共に、該スロット4の歯先側側壁の上端部には弧状の係止突部7を形成してある。
また、前記取付体3の歯先側基部には、屈曲可能な係止片8をタイウイング6と同方向に突設して、ベース2との間に軸溝9を形成してある。
Next, embodiments of the present invention will be described with reference to the accompanying drawings. The bracket of the present embodiment is particularly used for orthodontic correction such as premolars.
1 to 5, reference numeral 1 denotes a bracket body, and an attachment body 3 is erected on a flat base 2 fixed to teeth.
The attachment body 3 is provided with a slot 4 for accommodating the archwire W in the near-centrifugal direction in the upper central portion.
Further, a T-shaped hook 5 is projected along the slot 4 on the gum side outer side of the slot 4, and a tie wing 6 is projected on the tooth tip side outer side of the slot 4 in the direction opposite to the hook 5. In addition, an arcuate locking projection 7 is formed at the upper end of the tooth tip side wall of the slot 4.
Further, a bendable locking piece 8 is provided in the same direction as the tie wing 6 at the tooth tip side base of the mounting body 3, and a shaft groove 9 is formed between the base 2 and the base 2.

20は弾性板で形成したロック部材であって、その基部には前記軸溝11に挿入し得る軸部21を設け、該軸部21の両端部には取付体3の両側壁12,12に沿ってスライドし得る一対の腕部22,22を設け、両腕部22の先端部は結合されていると共に全体を側面L状に屈曲して、前記係止突部7からスロット上に亘り圧着係止し得る引掛け部23を形成してある。
而して、軸部21を前記軸溝9内に挿入し、前記係止片8を下方に屈曲させて軸溝9を閉塞することにより、回動可能に軸着されている。
Reference numeral 20 denotes a lock member formed of an elastic plate, and a base portion 21 is provided with a shaft portion 21 that can be inserted into the shaft groove 11, and both side walls 12, 12 of the mounting body 3 are provided at both ends of the shaft portion 21. A pair of arm portions 22, 22 that can slide along is provided, the tip portions of both arm portions 22 are joined, and the whole is bent into a side L shape, and is crimped from the locking projection 7 onto the slot. A hook portion 23 that can be locked is formed.
Thus, the shaft portion 21 is inserted into the shaft groove 9, the locking piece 8 is bent downward to close the shaft groove 9, and the shaft portion 21 is pivotally attached.

次に作用につき説明すると、図3に示すように、アーチワイヤWをスロット4内に収容した後、引掛け部23をピンセットのような器具で実線で示す方向に押すと、両腕部22,22は軸部21を支点として、取付体1の側壁12、12に沿ってスライドする。
而して、引掛け部23を係止突部7上に被せるようにしてに強く押圧すると、該引掛け部23は係止突部7上に圧着係合すると共に、引掛け部23の先端部は、その弾力でスロット4内のアーチワイWを上から強く押え込む。
また、スロット4内よりアーチワイヤWを取外すには、引掛け部23を鎖線で示す方向に強く押すと、引掛け部23が係止突部7上から離脱するので、スロット上部が開放され、直ちにアーチワイヤWをスロット4から取り出すことが出来る。
また、取付体3の外側部には、フック5及びタイウイング6を夫々配設してあるので、該フックとタイウイング間にリガチャーワイヤを掛け渡すことによって、アーチワイヤWをスロット内に縛着することもできる。
Next, the action will be described. As shown in FIG. 3, after the archwire W is accommodated in the slot 4, when the hook portion 23 is pushed in the direction indicated by the solid line with an instrument such as tweezers, 22 slides along the side walls 12 and 12 of the attachment body 1 with the shaft portion 21 as a fulcrum.
Thus, when the hooking portion 23 is strongly pressed so as to cover the locking projection 7, the hooking portion 23 is pressure-engaged and engaged with the locking projection 7 and the tip of the hooking portion 23. The part strongly presses the arch wai W in the slot 4 from above with its elasticity.
Further, in order to remove the archwire W from the inside of the slot 4, when the hooking portion 23 is pressed strongly in the direction indicated by the chain line, the hooking portion 23 is detached from the locking projection 7, so that the upper portion of the slot is opened. The archwire W can be immediately taken out from the slot 4.
In addition, since the hook 5 and the tie wing 6 are arranged on the outer side of the attachment body 3, the arch wire W is tied in the slot by passing the ligature wire between the hook and the tie wing. You can also

次に、本考案における別実施例を図6及び図7で説明する。なお、上記実施例1と同じ構成部分には同一の符号を付した。
上記実施例1では、アーチワイヤWを収容するスロット4をベース2面に対して直角向きに形成したのに対して、本実施例では、該スロット4をベース2面に対して所要角度α傾斜させて、該スロット4の開口面がフック5側に向くように形成してある。
また、上記実施例1においては、取付体3をベース2の中央部に固着してあるが、本実施例においては、ベース2の歯先側を一段と長く形成して、取付体3をベース2の歯茎側部に固着してある。このベース2は歯面が比較的縦長の前歯や犬歯に接着し易いようにした。
Next, another embodiment of the present invention will be described with reference to FIGS. In addition, the same code | symbol was attached | subjected to the same component as the said Example 1. FIG.
In the first embodiment, the slot 4 that accommodates the archwire W is formed in a direction perpendicular to the surface of the base 2, whereas in the present embodiment, the slot 4 is inclined at a required angle α with respect to the surface of the base 2. Thus, the opening surface of the slot 4 is formed so as to face the hook 5 side.
In the first embodiment, the attachment body 3 is fixed to the central portion of the base 2. However, in this embodiment, the tooth tip side of the base 2 is formed to be longer and the attachment body 3 is formed into the base 2. It is fixed to the side of the gums. This base 2 was made easy to adhere to front teeth and canines whose tooth surfaces are relatively vertically long.

また、ロック部材20の形状も上記実施例1のものと類似であるが、両腕部22、22の引掛部23側の後側部24を、係止突部7の外側に当接できるように所要角度屈曲させてあるところが相違する。
なお、アーチワイヤの固定及び開放操作は実施例1と同様であって、引掛け部23を係止突部7上に被せるようにして強く押圧すると、背部分24が係止突部7に当接すると同時に、引掛け部23の先端部がスロット4内のアーチワイヤWを強く押え込む。
而して、上記のように形成したことにより、本実施例におけるブラケットは、特に、歯面がやや長めの前歯や犬歯の歯列矯正に使用すると、ブラケットを歯面に固着し易いと共に、アーチワイヤを適正位置に確実に止着でき、その作業も容易である。
Further, the shape of the lock member 20 is similar to that of the first embodiment, but the rear side portion 24 of the both arm portions 22 and 22 on the side of the hooking portion 23 can be brought into contact with the outside of the locking projection 7. The difference is that it is bent at the required angle.
The fixing and releasing operation of the arch wire is the same as that of the first embodiment, and when the hook portion 23 is put on the locking projection 7 and pressed strongly, the back portion 24 contacts the locking projection 7. Simultaneously with the contact, the tip of the hook 23 strongly presses the archwire W in the slot 4.
Thus, the bracket in this embodiment is formed as described above, and particularly when used for orthodontics of slightly longer front teeth and canines, the bracket is easily fixed to the tooth surface, and the arch The wire can be securely fixed at an appropriate position, and the operation is easy.

歯列矯正を行うに際し、アーチワイヤの固定及び開放操作を、確実且つ容易に行うことが出来るので、歯列矯正作業において有効に利用することが出来る。   When performing orthodontic treatment, the archwire can be fixed and released reliably and easily, so that it can be effectively used in orthodontic work.
