Description

[Detailed explanation of the idea] (Industrial application field) This invention concerns scissors.

(Prior Art) Conventionally, as shown in Fig. 10, in right-handed scissors, which are mainly produced, the thumb is inserted into the tip 20 of the finger ring B on one side of the scissors to ensure a good contact. The other finger ring B has a slope 21b in a direction different from the slope of the one finger ring B so that fingers other than the thumb can comfortably touch the finger ring B.
There was one with a .

(Problem to be solved by the invention) However, the scissors configured as described above have the slopes 21a, 2 of the tip part 20 of the finger ring B for right-handed users.
1b, when a left-handed person uses the scissors with his left hand, his fingers do not fit into the tip 20 of the finger ring B, making it difficult to use the scissors.

Structure of the invention (means for solving the problem) This invention was made to solve the above problem, and includes a finger-rest side end of the blade that is pivotably supported on a rotating shaft so as to be openable and closable. The part is composed of a fork-shaped finger rest member protruding from the finger rest side end, and an arc-shaped finger rest member reversibly installed between the tip parts of the finger rest member. It is equipped with a finger ring A.

(Function) When the arcuate finger rest member installed between the tips of the finger rest members constituting the finger ring is placed on either the left or right finger of the user, the scissors are used in response to that finger. It will be flipped in the direction that is easier.

(Example) Below, examples that embody this idea are shown in Figures 1-
This will be explained according to FIG.

Reference numerals 1 and 2 denote a pair of blade bodies made of metal, which are rotatably supported by a rotation shaft 3 at substantially the center of each other, and have blade bodies 1a and 2a at their tips, respectively. Reference numeral 5 denotes a finger-rest member protruding from the finger-rest side end portions of the double-edged blades 1 and 2, and is formed into a bifurcated shape so that it becomes wider toward the tip.

Reference numeral 6 designates through holes that are formed through the tip portions of the finger hook members 5 so as to face each other. 7 is the finger hook member 5
This is a finger rest member installed between the distal ends of the finger rest, and a protrusion 8 protruding from both ends of the finger rest member is pivotally supported with respect to both the through holes 6 so as to be able to rotate in reverse. The finger rest member 7 is formed in the shape of a cylinder curved into an arc,
It is rotated in the opposite direction when the base of the finger hits it.

The finger rest member 5 and the finger rest member 7 constitute a finger rest ring A.

Now, the operation of the scissors configured as described above will be explained.

In the state where the arc-shaped finger rest member 7 is in the state shown in FIG. 2, when a right-handed user places his or her right fingers on the scissors, the finger rest member 7 on the side where the thumb rests will adjust to the state near the base of the thumb. They are arranged in an arc shape toward the left. Further, the finger rest member 7 on the other side is arranged in an arc shape toward the right side depending on the condition of the base of the finger other than the thumb, for example, the ring finger, so that it is easy to use the scissors.

Further, especially when a left-handed user uses the scissors shown in FIG. Then, both the finger rest members 7 are rotated invertedly around the protrusion 8 to the position shown in FIG. 3 by being touched by the thumb and the fingers other than the thumb, respectively. That is, the finger rest member 7 on the side on which the thumb rests is arranged in an arc shape toward the right depending on the state near the base of the left thumb, and the finger rest member 7 on the other side is arranged in an arc shape near the base of the fingers other than the thumb. The scissors are arranged in an arc shape toward the left side, making it easier to use the scissors.

(Second Embodiment) Next, a second embodiment will be described with reference to FIGS. 4 to 6 only with respect to the differences from the first embodiment.

In this embodiment, a coiled spring 14 serving as a finger rest member is installed between the distal ends of the finger hook member 5 from which the through hole 6 is omitted, and whose both ends are embedded and fixed in the distal ends thereof. Further, the coiled spring 14 is longer than the length between both ends thereof, and is shaped like an arc.

As described above, the finger ring A is composed of the finger ring member 5 and the coiled spring 14.

In this embodiment, when the user places the fingers of the right hand on the scissors, the arc-shaped coiled spring 14 resists its own elasticity and changes to the state shown in FIG. 5 according to the state of the fingers, making it easy to use the scissors. . Further, when a left-handed user uses scissors with his/her left hand, the coiled spring 14 resists its own elasticity and adjusts to the sixth position according to the condition of the fingers.
It is easy to use scissors because it is reversed beyond the line X-X' shown in the figure.

It should be noted that the present invention is not limited to the above-mentioned embodiment, and as shown in FIGS. 7 to 9, a plate spring 18 is fixed in place of the coiled spring 14 as a finger rest member, and as shown in FIG. Any changes can be made without departing from the spirit of the present invention, such as by inverting it beyond the Y-Y' line.

Effects of the Invention As detailed above, according to the present invention, the finger rest member provided at the tip of the finger ring is shaped like an arc so that not only right-handed users but also left-handed users can easily place their fingers on it. It has the excellent effect of being able to be reversed.
