Description

[Detailed description of the invention] This invention relates to barber scissors used exclusively for cutting hair.

Scissors are generally made up of two scissor members, each consisting of a sword part with a blade formed on one side edge and a handle part with finger holes, which are intersected so that the blades face each other, and the intersecting parts are pivotally connected. This involves inserting the fingers (mainly the thumb and index finger) into the finger holes and cutting the object by opening and closing the blade.
Barber scissors have unique characteristics depending on the user, so it would be very convenient to have a pair of scissors that can be adjusted in size and angle to suit the user. Conventionally, finger holes are formed separately so that they can be attached and detached as appropriate. This attachment/detachment mechanism has a handle portion that is rod-shaped, has several thin grooves circumferentially extending along the longitudinal direction of its surface, and has protrusions corresponding to the thin grooves formed on the inner surface of a cylindrical body from which finger holes are separately provided. At the same time, the outer surface of the tip is tapered, a nut is screwed into the tapered part, and the cylindrical body inserted into the rod-shaped handle is fixed by tightening the nut.

However, the above-mentioned scissors with replaceable finger holes are complicated to manufacture, such as forming a thin groove in the rod-shaped handle, forming a protrusion on the cylindrical body, and forming a nut attachment part in the tapered part. The selection of the inclination angle with respect to the rotating surface is limited by the narrow groove.

Therefore, the present invention is designed to be easier to manufacture and to allow the finger holes to be attached to the rotating surface at any angle. The details will be explained next based on the drawings.

The barber scissors of this invention consist of a scissor body and a finger hole part, and the scissors body has two scissor members each consisting of a sword part 1 with a blade formed on one edge and a rod-shaped handle part 2, crossed in an X shape, and the crossed parts are pivoted as appropriate. This is what happens. The finger hole body is the rod-shaped handle 2
A fastening band 4 made of a shape memory alloy for holding pressure is attached to the resin cylindrical part 3 into which the finger can be inserted, and the finger hole part 6 is poked so that a finger hole 5 of a predetermined size and shape is formed. The fastening band is attached so as to surround the outer peripheral surface of the cylindrical part 3, and the fastening band is attached to the cylindrical part 3 at room temperature.
It has a shape that presses a part of it against the inner capsule, and at high temperatures (for example, set a temperature appropriately higher than the human body temperature, such as about 60 degrees Celsius), it has a shape memory that changes to a shape in which the pressure is released. It is something that It is better that the part of the cylindrical part 3 that is pressed by the inner fastening band 4 is flexible, but the finger hole part 6 that forms the finger hole 5 needs to be appropriately hard because if it is too flexible, it will be difficult to use. , it may also have a double structure as shown in FIG.

When inserting the cylindrical part 3 of the finger hole body into the rod-shaped handle part 2, the finger hole body is heated to a predetermined temperature or higher by, for example, immersing it in hot water, and the inward pressure of the fastening band 4 is released. Then, move the finger hole body so that the position of the finger hole 5 is at the desired position, and when it is left or cooled, the fastening band 4 changes its shape to press inward, and the finger hole body is attached to the rod-shaped handle part 2. It is something that sticks. At this time, if the surface of the rod-shaped handle part 2 is made rough, the finger hole will be more securely fixed.

Therefore, the position of the finger hole 5 (distance from the intersection and inclination with respect to the rotating surface) can be changed steplessly and can be formed at a desired position.

[Brief explanation of drawings]

The drawings show an embodiment of the present invention, in which Fig. 1 is an overall perspective view showing the state of use, Fig. 2 is a front view of each member, and Fig. 3 is an enlarged front view with a part of the finger hole body cut away. 1 is a sword part, 2 is a rod-shaped handle part, 3 is a cylindrical part, 4 is a fastening band, 5 is a finger hole, and 6 is a finger hole part.
