Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to the structure of scissors, and particularly to the structure of replaceable blade type scissors whose blades can be easily replaced.

(Prior art) Generally, scissors have a movable blade with a thumb handle ring on one end and a static blade with a ring finger handle ring on one end, which intersect in an X-shape, and the crossing position is pivoted. It cuts hair, paper cloth, etc. by crossing a moving blade and a static blade.

(Problem to be solved by the invention) By the way, the conventional scissors described above suffer from wear and tear on the blades due to long-term use, or when the blades are damaged due to hitting a pebble or the like. It became impossible to use the scissors, and new and different scissors had to be used, resulting in disadvantages such as being uneconomical. Furthermore, when hairdressing scissors lose their sharpness, the blades of the scissors must be sharpened, but this work requires great skill and is very time-consuming.

The purpose of this invention was to solve the above-mentioned drawbacks by configuring scissors with replaceable blades, and to provide economically superior scissors. be.

(Means for Solving the Problems) The present invention combines a movable blade base with a finger handle ring on one end and a stationary blade base with a hand handle ring on one end in an X-shape. In replaceable blade type scissors that are crossed and pivoted at the crossing position, on the inner surface of both or at least one of the bases, from the bevel direction toward the tip of the part where the blade is formed, on the inside of the base. To provide replaceable blade type scissors, characterized in that a blade attachment part having a concave curvature is provided, and a plate-shaped blade is removably adhered to the blade attachment part by double-sided adhesive tape along the curvature. By doing so, the purpose is achieved.

(Function) If the old blade attached to the blade attachment part of the base for moving blades or the base for static blades is damaged or has reached the end of its life, only that blade can be attached to the base for moving blades or static blades. Peel it off from the base and glue the other new blade with the Rikei paper peeled off there.

(Example) An example of the present invention will be described in detail using the drawings.

Figure 1 is a perspective view showing the replaceable blade type scissors of the present invention;
FIG. 2 is a sectional view showing a state in which the replaceable blade is adhered to the blade attachment part. In the figure, 1 is a movable blade base with a thumb handle ring 2 at one end, and 3 is a ring finger handle ring 4 at one end.
This is a base for static blades. The two bases 1 and 3 intersect in an X-shape, and the intersection position is the screw 5.
It is pivoted by. Reference numeral 6 denotes a blade attachment part of the movable blade base 1, and as shown in FIG. A sled 6c that is recessed inside the blade attachment portion 6 is provided toward the tip 6d. Reference numeral 7 denotes a blade attachment portion provided on the stationary blade base 3. Then, the blade 8 is attached to the blade attachment parts 6 and 7.
However, since the blade attachment parts 6 and 7 have the same structure, in this embodiment, the movable blade base 1
The details will be explained using . The movable blade base 1 and the static blade base 3 intersect in an X-shape, and the intersection is pivotally supported by a screw 5, so that when a blade 8, which will be described later, is attached and used, the blade 8 and The blade 8 attached to the sled 6c is curved along the sled 6c, and the blade attachment parts 6 and 7 are twisted so that the blade 8 can operate while intersecting at one point. be. Note that the twisting method is the same as the method generally used for scissors, so the details will be omitted.

FIG. 3 is a plan view of the blade attachment part 6 of the movable blade base 1;
FIG. 4 is a side sectional view taken along line A-A' in FIG. In the figure, 6a is a positioning protrusion provided near the shaft support of the blade attachment part 6, and 6b is a positioning flange provided on the back of the blade attachment part 6. The blade attachment portion 6 is shown in FIG. 4, and as described above, a sled 6c is provided on the side (inside) where the blade 8 is attached. FIG. 5 is a plan view of the blade 8, and FIG. 6 is an enlarged sectional view. In the figure, the blade 8 is made of a thin metal plate such as a steel plate or a stainless steel plate, and has a shape slightly larger than the blade attachment part 6, and has a hole 8a that engages with the positioning protrusion 6a, and a positioning flange part 6b. It has an abutting edge 8b and a blade portion 8c (see FIG. 6) that abut against the edge. 9 is a double-sided adhesive tape provided on one side of the blade 8, 10 is paper provided on the adhesive tape 9, and 11 is a tongue such as a tape removably provided on the other side of the blade 8. It's a piece.

Next, to explain in detail how to attach the blade to the blade attachment part 6, first, hold the tongue piece 11 with one finger and peel off the paper 10 of the blade 8 with the other finger.
If the hole 8a provided in the blade 8 is engaged with the protrusion 6a of the blade attachment part 6, and the contact edge 8b is brought into contact with the flange part 6b, and after positioning, the blade 8 is held down on the blade attachment part 6b. The blade 8 is attached to the blade attachment part 6 using double-sided adhesive tape 9, and the blade part 8c of the blade 8 slightly protrudes from the tip 6d of the blade attachment part 6. At this time,
The blade 8 had a flat plate shape, but since a curvature was provided inside the blade attachment part 6 described above, when the blade 8 was attached to the blade attachment part, the blade was warped inward as shown in FIG. It is as if the following is provided. Also, although not particularly shown, the blade attachment part 7 of the stationary blade base 3
The blade 8 may be attached to the blade 8 in the same manner as described above. After the attachment of the blade 8 is completed, the tongue piece 11 can be peeled off from the blade 8 and removed.

In this way, insert your thumb into the thumb handle ring 2 and insert your ring finger into the ring finger handle ring 4 of the replaceable blade type scissors with the blade 8 glued to the blade attachment parts of the static blade base and the movable blade base. By operating the bases 1 and 3, hair, paper cloth, etc. can be reliably and sharply cut by the blades 8 and 8.

Furthermore, if the blade 8 is damaged or its life has come to an end, only that blade 8 can be peeled off from the base 1 or 3 and the next blade 8 can be bonded.

In addition, in the above embodiment, the movable blade base 1
The blade 8 is attached to both the base 3 and the stationary blade base 3. However, for example, the blade 8 may be provided directly on one of the bases so that only one side can be removed. It is okay to do so.

(Effects of the invention) As explained in detail above, the invention provides a blade made of steel plate, stainless steel plate, etc., rather than double-sided adhesive tape, on both or at least one of the base for the moving blade and the base for the static blade. Since the blade is glued, if the blade breaks or reaches the end of its service life, just peel that blade from the movable blade base or static blade base and glue another new blade there, and the other parts will be replaced. can be used as is and has economical effects.

Further, since the blade attachment portion of the base is provided with a curvature, the blade attached to this is also formed with a curvature along this curvature. For this reason, combined with the twist applied to the base, when the scissors perform a cutting operation, the cutting edges of the blades attached to the stationary blade base and the movable blade base intersect at one point, and Since the blade is plate-shaped and made of a thin elastic steel plate, the meshing of the blades acts on a soft fit, resulting in a sharp cutting effect.
