Description

【考案の詳細な説明】本考案は、理髪店等で使用するサインポールに関する。[Detailed explanation of the idea] The present invention relates to a sign pole used in barber shops and the like.

サインポールの回転筒は、材料や構造の関係上回転筒の
センターやバランスが均一化しに＜＜、筒のセンター軸
と駆動モータの回転軸を直結させる事が出来ず、モータ
の回転運動の伝達は回転筒の軸の中心に凹部を設け、回
転軸に、円錐形の接触軸を取り付け、該接触軸の頂点を
前記凹部と接触させることにより行なっていた。Due to the material and structure of the rotating cylinder of the sign pole, the center and balance of the rotating cylinder must be uniform, and the center axis of the cylinder cannot be directly connected to the rotating shaft of the drive motor, making it difficult to transmit the rotational motion of the motor. This was accomplished by providing a recess in the center of the shaft of the rotating cylinder, attaching a conical contact shaft to the rotating shaft, and bringing the apex of the contact shaft into contact with the recess.

従って、筒のバランスはとり易くても、接触軸と回転筒
との接触面積が小さいので伝達起動力が非常に弱く回転
筒が、正常回転に達する迄にかなり時間を要する。Therefore, even though it is easy to balance the cylinder, since the contact area between the contact shaft and the rotating cylinder is small, the transmitted starting force is very weak, and it takes a considerable amount of time for the rotating cylinder to reach normal rotation.

本考案はこの欠点を改良し、接合面を大きくしてスリッ
プを防ぐと共にアンバランスの筒でも簡単に回転中自刃
でセンターが定まり回転がスムースに出来るようになし
たのである。The present invention has improved this drawback by making the joint surface larger to prevent slippage, and even with an unbalanced cylinder, the center can be easily determined by the self-cutting blade during rotation, allowing smooth rotation.

A drive motor 2 is attached to the lower part of the outer cylinder 1 of the pole, and a contact shaft 4 made of a friction dog member such as frustoconical rubber or synthetic resin is fixed to the tip of the rotating shaft 3 of the drive motor 2. On the other hand, a circular hole 7 with a smaller diameter than the base of the contact shaft 40 is bored in the center of the lower bottom 6 of the rotary cylinder 5 to be inserted into the outer cylinder 1, and a material such as rubber or synthetic resin is formed around the circular hole I. Attach the surrounding body 8 which includes a friction dog member, insert the rotary cylinder 5 into the outer cylinder 1, fit and place the circular hole 7 on the contact shaft 4, and set the center of the upper wall 9. is rotatably supported on a center shaft 10 fixed to the outer cylinder 1.

ーを定めることができるのである。In short, in the present invention, a conical contact shaft 4 is attached to the rotating shaft 3 of the drive motor 2 attached to the lower part of the outer cylinder 1 of the Sai7 pole, and the contact shaft 40 is attached to the center of the lower bottom 6 of the rotating cylinder 5. A center shaft 10 is provided with a circular hole 7 having a smaller diameter than the diameter of the base, the rotary cylinder 5 is inserted into the outer cylinder 1, the circular hole 7 is fitted to the contact shaft 4, and the center shaft 10 is fixed to the outer cylinder 1. Since the shaft is rotatably supported, the contact area between the rotary cylinder and the contact shaft is widened, preventing slippage between the rotary cylinder and the contact shaft, allowing the rotary cylinder to rotate normally as soon as the switch is turned on, and Even if the cylinder is unbalanced, the center can be determined using the self-cutting blade during rotation.
