Abstract

PURPOSE:To make particularly better the sharpness of scissors for haircut and beauty, and to make also better that or stationery since a movable blade for the scissors is shifted by the compound motion of both straight and rotation, by a method wherein one piece of the scissors is divided into the movable blade and an operating handle, and both the movable blade and the operating handle are connected through a fitting spindle and a shifting device for the movable blade, and the operating handle is integrally fitted with the other piece of the scissors. CONSTITUTION:A through hole 3 having a rack 2 parallel to the longitudinal direction of a movable blade 1 for scissors, is provided on the base side of the movable blade 1 and a sector gear 4 is engaged with the rack 2. A top side 7 of an operating handle 5 is inserted into grooved parts 6 on the base side of the movable blade 1. The operating handle 5, the sector gear 4 and an operating handle 8 are integrally fitted with a piece of the scissors which consists of a blade 9 integrally formed, by a fitting spindle 10 for common use and a nut 11. When fingers inserted into finger openings 13, 14 are approached each other toward arrow marks 15, 16, the sector gear 4 is turned in the direction of an arrow mark 17, and the movable blade 1 is circularly moved centering around the fitting spindle 10 while being moved straight toward an arrow mark 18. In this way, hair can be cut easily and smoothly.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to hairdressing and beauty scissors whose purpose is to cause the scissors to make combined rotational and linear movements during cutting.

(Prior Art) Conventionally, the scissors pieces of barber/cosmetic scissors have been able to move in a circular motion around a mounting shaft.

(Problems to be Solved by the Invention) Since barber/cosmetic scissors cut hair that is relatively difficult to cut, it is preferable to cut the hair without applying any rubbing force to the hair. However, when cutting something, it is generally known that slightly shifting the blade makes the cut smoother than simply pressing down on the blade, but the conventional scissors are mounted on a common mounting shaft. Because of this, it was impossible to shift the scissors, and there were some defects in the smoothness of cutting.

(Means for Solving the Problems) However, the present invention solves the above-mentioned conventional problems by making the iron B of one of the scissors pieces movable.

That is, in this invention, one scissors piece is separated into a movable scissors blade and an operating handle, and the movable scissors blade and the operating handle are connected via a mounting shaft and a moving means for the movable scissors blade, and the operating handle is These hair and beauty scissors are characterized by a handle and the other scissor piece being integrally attached. As the moving means in this case, a known interlocking mechanism such as a combination of a rack and a pinion or a combination of a protrusion and a groove can be used.

Further, in another invention, a through hole having a linear tooth pattern is provided on the base side of one of the movable scissor blades, a gear is engaged with the linear tooth pattern, and the tip side of the operating handle is slid on the base of the movable scissor blade. The operating handle, the gear, the gear, the operating handle, and the other scissors integrally made of iron B are attached to each other by a common mounting shaft, and the operating handle, the gear, the gear, and the other scissors are attached to each other by a common mounting shaft. This barber/beauty scissor is characterized by having a pair of scissors hooked in the direction of rotation. The gear mentioned above is a pinion or a sector gear, which can be arbitrarily selected. In the above, the operating emphasis (
For example, since the mutual relationship between the finger hole) and the fulcrum (mounting shaft) does not change, there is no risk of discomfort during operation, and the scissors can be used in the same way as conventional hair and beauty scissors.

Also, it is possible to reduce the contact area between the base of the movable scissor blade and the tip of the operating handle (by providing a groove or protrusion).
, the contact resistance between the two can be reduced, and sliding can be made even smoother.

(Function) In this invention, since one side of the iron B is made slidable, the iron B automatically performs a compound movement of linear movement and rotational movement while operating the scissors.

(Example 1) An example of the present invention will be described with reference to FIGS. 1 to 3.

In FIG. 1, a through hole 3 having a linear tooth profile 2 parallel to the longitudinal direction of the movable scissor blade 1 is provided on the base side of the movable scissor blade 1, and a sector gear 4 is meshed with the linear tooth profile 2.

The distal end 7 of the operating handle 5 is fitted into the groove 6 on the proximal end of the movable scissor blade 1 . A scissors piece made of iron B9 integrally formed with the operation handle 5, sector gear 4, and operation handle 8 is integrally attached with a common mounting shaft 10 and nut 11. The prismatic portion 10a of the mounting shaft 10, the mounting hole 4a of the sector gear 4, and the mounting hole 9a of the iron B9 are fitted, and the sector gear 4 and the iron B9 are restrained in the rotational direction. Note that although the operating handle 5 and the mounting shaft 10 are rotatable, their linear movement is restricted. Therefore, the scissors 12 are assembled as shown in FIG. 2, and the movable scissors blade 1, sector gear 4 and operating handle 5 are assembled as shown in FIG. In the figure, 19 is a groove.

In the above embodiment, when the fingers inserted into the finger holes 13.14 in FIG. 2 are brought close together as shown by arrows 15 and 16, the sector gear 4 rotates as shown by arrows 17 in FIG. 3, and becomes movable. Since the scissor blade 1 is moved linearly in the direction of the arrow 18 and also moved circularly around the attachment shaft 5, hair can be cut easily and smoothly.

(Embodiment 2) The embodiment shown in FIGS. 4 and 5 uses a groove and a protrusion as a means for moving the movable scissor blade 1 in the first embodiment.

That is, a long hole 20 is provided on the base side of the movable scissor blade 1, into which the mounting shaft 10 fits loosely, and an arcuate groove 22 into which a projection 21 of iron B9 is fitted is bored.

In the embodiment described above, when the operating handles are brought close to each other as shown by arrows 23 and 24 in FIG. Become. 26 in the figure is a piece.

(Effect of the invention) In this invention, since a moving means is interposed between the movable scissors blade and the operation handle or the iron B, the movable scissors blade can perform a combination of linear motion and rotational motion by the operation of using the scissors. It has the effect of exercising. Therefore, it is possible to improve the cutting edges.
