手段も知られている。2. Description of the Related Art The basic structure of scissors is to cross a pair of swords in an X-shape and to form an axial hole passing through both swords, as is well known.
The crossing portion is pivotally connected by a pivot shaft inserted through the shaft hole. Moreover, the pivot shaft portion does not exhibit a smooth cutting action if it is loose in the axial direction, so it is necessary to tighten it to some extent. However, if the blades are tightly tightened, the sword body may not rotate smoothly, and there is known a means of interposing a resin washer between the blades so that the blades can be smoothly moved even with strong tightening. No. 50517, etc.). As shown in FIG. 7, instead of the resin washer, the sword body 0
There is also known a means for forming a recessed portion 04 on the opposing surface of the mounting portion of the pivot shaft 03 of 1.02 and mounting the bearing body 05 in the recessed portion 04.

を提案したものである。However, in actual use, the cut hair becomes fine cut pieces and adheres to the barber scissors.
A part of it penetrates into the recess 04 that houses the bearing body 05. Moreover, in the conventional barber scissors, the bearing ball directly contacts the sword body (bottom surface of the recess) and rotates,
The hair fragments that have entered the recesses 04 are likely to adhere to the bottom surface of the recesses and the surface of the bearing body, and particularly when adhered to the bottom surfaces of the recesses at the bearing ball passing positions, the hair fragments will intervene in the operating portion, Its usability is significantly reduced.
Therefore, the present invention proposes barber scissors in which a new bearing body is interposed.

徴とするものである。The barber scissors according to the present invention are:
In a barber scissor in which a pair of swords are crossed in an X shape, and the crossing parts are pivotally connected by a pivoting screw and a fastening nut that penetrate both swords, a bearing ball is interposed between the inner and outer double cylinders. The bearing body is installed in a recess provided on the opposing surface of the sword body of the pivotal connecting portion, and the sword body on the side that integrally rotates with the pivoting screw and the fastening nut and the inner cylinder of the bearing body are connected together in a rotating manner. It is characterized in that the other sword body and the outer cylinder of the bearing body are connected together.

Is brought into contact with the bottom surface of the recess of each sword body, or a connecting plate is interposed between the end edges of the inner and outer cylinders of the bearing body and the bottom surface of the recess.

Since it adheres to the end surface of the bearing body, it is less likely to enter the periphery of the bearing ball, which is the operating portion of the bearing body. In addition, the bottom surface of the concave part of the sword body can be formed by sloping,
Alternatively, when the sword body is made to approach in the axial direction with the connection plate interposed, only a part of the inner and outer cylinder end edges of the bearing body comes into contact with the sword body, and is jointly rotated.

The barber scissors according to the present invention has a basic configuration in which a pair of sword bodies having finger holes 2a, 2b formed at the ends of the sword bodies 1a, 1b are crossed in an X-shape, and the shaft is formed at the crossing portion, as in the conventional one. The holes 3a and 3b are formed, and the recesses 4a and 4b are formed on the sword body facing surfaces around the shaft holes 3a and 3b. The bearing body 5 is housed in the recesses 4 and penetrates the shaft holes 3a and 3b. The tightening nut 7 is screwed onto the pivoting bolt 6 to be pivotally connected.

になる。In particular, the bearing body 5 is an inner / outer double cylinder body 5.
A bearing ball 53 is interposed between the first and the second halves, and the bottom surface of the concave portion 4a of the sword body 1a has a shallow (high) edge portion (shallow portion 41) of the shaft hole 3a on the side of the finger hole 2a. Is formed deep (low) to form an inclined surface as a whole, while the concave portion 4b of the sword 1b is shallow (high) on the tip side (shallow portion 42) of the sword and deep (low) on the other side. Become. Then, the bearing body 5 is housed in the recess 4 and the pivoting bolt 6 is mounted therethrough,
When the tightening nut 7 is screwed and tightened, a part of the inner cylinder 51 of the bearing body 5 contacts the shallow portion 41, and a part of the outer cylinder 52 contacts the shallow portion 42.
Only part of it will be sandwiched between the sword bodies 1a and 1b.

発生の原因とならないようにしたものである。Further, in the embodiment, a locking mechanism for the tightening nut 7 using the leaf spring body 8 is additionally provided. In the locking mechanism, a radial uneven surface 71 is provided on the bottom surface of the tightening nut 7, and the sword body 1b. The fixing hole portion 11 of the leaf spring body 8 is bored on the surface of the leaf spring body 8, and the leaf spring body 8 is bored with a shaft hole 81 in the central portion thereof, and the whole peripheral portion of the shaft hole 81 is bulged so as to have an arc shape in a side view. State, the insertion piece 82 to the fastening hole portion 11 is provided at one end,
Small projections 83 corresponding to the radial concavo-convex surface 71 are provided on the upper surface of the peripheral portion of the shaft hole 81, and the small projections 8 are sandwiched by the shaft hole 81.
On the opposite side of 3, a part of the leaf spring body 8 is bent to project the protrusion 84.
Is formed. In this loosening prevention mechanism, the uneven surface 71 on the bottom surface of the tightening nut 7 meshes with the small protrusions 83 of the leaf spring body 8 to prevent the loosening. In particular, the tightness nut 7 is strongly screwed and the leaf spring body 8 is tightened. When the protruding portion 84 comes into contact with the surface of the sword body 1b, the movement of the tightening nut 7 in the axial direction is restrained, so that even if a force acts in the axial direction of the pivot shaft during the hair cutting operation, the force is exerted on the shaft. Good movement is maintained without the movement of a predetermined fulcrum. That is, the elastic force of the leaf spring body 8 for preventing the tightening of the tightening nut 7 is exerted only on the portion that performs the anti-loosening action so that the elasticity does not cause the axial elastic force of the nut itself.
