Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides that a separately manufactured pivotable finger hole of a movable ferrous half has a proximal end at its outer edge, which proximal end extends into a recess in the handle of the movable ferrous half. Relating to hairdressing, household or sewing scissors that are attached to hairdressers.

In the case of the scissors of the applicant's earlier application (Japanese Patent Application No. 54-301.13), the recess for the proximal end of the pivotable finger hole is located inside the two-pronged handle hole in the movable acid iron half. In this case, the handle hole has an arc-shaped groove on the inside, and the finger hole passes through this groove with play so that it can rotate only within a certain angular range. .

Scissors of this type have the important advantage in their operation that the thumb inserted into the movable finger hole rests entirely on the inner surface of the finger hole during opening and closing of the scissors.

Moreover, because the thumb can be pivoted towards the metal side, there is no relative movement between the thumb and the finger hole and thus no sliding friction, which is disadvantageous even when using the scissors for a long period of time. There isn't.

However, this type of scissors has the following disadvantages: Passing the rotatable finger hole into the handle hole or its groove is difficult.
A disadvantage, as practice has shown, is that the range over which the finger hole can rotate is often too small.

As a result, the thumb is rubbed as the finger hole pivots along the inner edge of the handle hole, which can be unpleasant, especially when using the barber scissors for a long period of time.

However, the passage of a rotatable finger hole into the groove of the handle hole is extremely necessary in the case of known scissors, i.e., the finger hole would otherwise be freely rotated through 360°. This is because it moves.

However, this has a disadvantageous effect, especially in the case of hairdressing shears: The hairdresser requires the shears and the comb alternately at short intervals.

For certain tasks, the scissors are held only with the ring finger so that the comb can be held and operated with the thumb, index finger, and middle finger.

Now, when the comb is released again, a difficulty arises when inserting the thumb into the pivotable tonghole, since the tonghole has to be aligned with the thumb, perhaps for the first time.

Furthermore, in consideration of the thickness of the fingers of a human hand, the rotatable finger hole cannot be replaced with a dog finger hole or a small finger hole.

Finally, the arrangement of the handle hole also has a disadvantageous effect with respect to the weight of the hairdressing shears, which must be handled particularly lightly by hand.

In a further embodiment of the Japanese Patent Application No. 54-30113 referred to at the outset, the pivotable finger hole is spherical on the outside and is pivotably mounted in a correspondingly shaped handle hole. .

The finger holes on these scissors can be replaced.

However, this scissors, apart from the disadvantages arising from the arrangement of the handle holes, is difficult because the finger holes can inadvertently be displaced past one or the other stop, despite the arrangement of the stops. It has the disadvantage that it has to be pulled out from the shaft and inserted into the shaft hole between the sharpening stops.

Therefore, it is an object of the present invention to improve the scissors of the present applicant's earlier application so that the swingable range thereof is sufficiently increased, particularly with regard to the attachment of the rotatable finger hole for inserting the thumb.

In this problem, the proximal end 18 passes through the ring part 17a to the finger hole 17.
and is rotatably supported in a recess 19 in the handle 12 of the movable oxidized iron half 11 which is integrally connected to the finger hole 17 and is open toward the finger hole 17. Said progenitor 18
An annular groove 17c into which a ring 17b is inserted to prevent removal.
This is solved by the formation of

This advantageously achieves that the pivotable finger hole can be freely pivoted without the conventional handle hole.

A ring securing the finger hole in the recess prevents the finger hole from being able to pivot freely.

That is, light finger pressure must be applied to the finger hole for rotation.

Furthermore, the movable finger hole can be replaced without effort due to the flexibility of the ring.

In other words, when the finger hole is pulled to take out the tip from the recess, or when the finger hole is pressed to put the tip into the recess, the ring is deformed and the finger hole is obstructed by the ring. This is because it can be taken out or inserted without any trouble.

After inserting the finger hole into the recess, the ring returns to its original shape and thereby secures the finger hole in the recess.

Furthermore, eliminating the handle hole reduces the weight of the scissors, which is particularly advantageous in the case of hairdressing scissors.

The present invention will be explained in detail below with reference to the drawings.

Barber scissors have a fixed scissors half part 1 having a finger hole 2 and a finger hole 1
7 and a mobile acid iron half 3.

The scissor halves 1, 3 are interconnected by a latch 5.

The finger hole 2 has a cylindrical extension 6 which fits tightly onto the handle 7 of the scissor half 1.

The finger hole 2 and the extension 6 are made in one piece from synthetic material.

The finger hole 17 has a cylindrical appendage 17a on its outer periphery, and one proximal end 18 is disposed in this appendage.

The finger hole 17, the appendage 17a and the proximal end 18 are manufactured in one piece from synthetic material.

The finger hole 17 is secured in the recess by a ring 17b which allows the proximal end 18 to be seated in a recess 19 and is made of flexible workpiece material and inserted into the annular groove 17c.

The recess 19 is formed into a cylindrical extension 11 which is tightly fitted onto the handle 12 of the scissor half 3.

The recess 19 together with the extension 11 is manufactured in one piece from synthetic material.

It is of course within the scope of the invention to arrange the finger holes 2 in the fixed scissor half 1 in the same way as the finger holes 17 in the mobile acid iron half 3.

[Brief explanation of the drawing]

FIG. 1 shows a front view of the hairdressing shears, and FIG. 2 shows an enlarged longitudinal cross-sectional view of a partially exposed mobile acid iron half. Symbols in the figure: 11: extension, 12: handle, 17b: ring, 18: proximal end, 19: recess.

Claims (1)

[Scope of Claims] 1. A separately manufactured pivotable finger hole of the movable iron half has a proximal end at its outer edge, and this proximal end is fitted into a recess in the handle of the movable half iron. In hairdressing, home use or sewing scissors, the proximal end 18 is integrally connected to the finger hole 17 through a ring portion 17a, and has a movable acid iron half portion which is open toward the finger hole 17. It is rotatably supported in a recess 19 of the handle 12 of 11, and a ring 1 is provided in the recess 19 to prevent the proximal end 18 from being pulled out.
Scissors for hairdressing, household use, or sewing, characterized in that an annular groove 17c into which the scissors 7b are inserted is formed.
