Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improving the replaceable blade of replaceable blade type scissors, and it simplifies the structure of the replaceable blade of the replaceable blade type scissors and makes it easy to attach and detach the replaceable blade. The purpose is to

Next, the configuration of the present invention will be explained with reference to the drawings showing examples. Reference numeral 2 denotes a blade body, and a recess 3 having an arcuate cross section is formed in the longitudinal direction of the blade body. Two elongated punched parts 4, 4 are bored in the recess. Reference numeral 5 denotes an operating protrusion provided on the blade body, on which the finger is placed when attaching or detaching the blade body.

The blade attachment surface 12 of the scissor blade attachment portions 1, 1 includes:
A groove 7 is formed in the longitudinal direction for receiving the extrusion 6 of the blade. The blade body 2 is in the groove 7.
Blade holding parts 8, 8 are integrally provided for pressing the recess 3 of the blade and fixing the blade when the blade is applied to the blade mounting surface 12. This blade holding part is L-shaped and has a gap into which a part of the recess 3 of the blade can be inserted, and the action of holding down the blade is performed by the elastic force of the holding plates 9, 9. Further, the back surfaces of the presser plates 9, 9 have an arcuate cross section in accordance with the shape of the recess 3. The side surfaces 10, 10 of the blade holding part do not protrude beyond the back surface 11 of the attached blade body. Reference numerals 13 and 13 shown in FIG. 1 are protrusions for regulating the movement of the operating protrusion 5, and the operating protrusion 5 projects outward from between the two protrusions. The protrusion 1
The height of 3 and 13 is not higher than the thickness of the blade body 2.

The degree of protrusion of the blade holding parts 8, 8 and the protrusion 13,
The reason why the height of the blades 13 is limited in this way is that if these protrude beyond the back surface 11 of the blade body, the blade edge 1 of the double blade body
This is because 4 and 14 cannot be crossed, making it impossible to use them as scissors.

To explain the operation of attaching the blade body to the embodiment, the blade holding parts 8, 8 are applied to the punched parts 4, 4 of the blade body, and after passing through the holding plates 9, 9, the blade body is slid backward. Then it will be attached to the blade mounting surface. If the operating protrusion 5 is used to move the blade, this can be done even more smoothly. In order to securely attach the blade body 2, the back surface of the presser plate 9 may be formed into an inclined surface downward toward the base thereof.

The present invention has the above configuration, and the structure of the blade body and the blade body mounting structure for mounting the same is simple, and the manufacturing cost can be reduced even though the scissors have replaceable blades. I can do it. Additionally, the blade can be attached and detached with a single touch, making it easy to use. In conventional replaceable blade scissors that use flat blades without undulations, the blades must be held on the blade mounting surface by some means. In that case, the blade retainer always gets in the way, making it impossible to open and close both blades, making it impossible to use the scissors. In the present invention, by forming the recess 3 in a part of the blade 2, the blade retaining parts 8, 8 in the recess do not protrude beyond the back surface 11 of the blade, and the above-mentioned inconvenience does not occur. There isn't.

Note that the present invention is not limited to the embodiment shown in the drawings; for example, the recess 3 of the blade body may not be open at both ends but may be a dead end. Moreover, the recessed portions may be substantially divided into several locations, even if they do not extend in a continuous manner.

There may be three or more blade holding parts 8 provided on the blade mounting surface 12, or there may be a single blade holding part 8. In the case of a single blade, the blade holding part 8 is attached to the support shaft 1.
5, and the blade holding plate 9 is much longer than that shown in the drawing.

Claims (1)

[Claims] 1. Scissors that can removably attach a replacement blade have a groove formed on the blade attachment surface of the scissors, and this part can receive the bulge formed on the blade, so that the blade can be attached to the blade. When applied to the body attachment surface, it passes through the punched part of the blade and protrudes into the recess of the blade, and when the blade is slid in its longitudinal direction,
A replacement blade that is removably attached to such scissors, which is provided with a blade holding part on the blade mounting surface, which has a gap into which the part of the blade adjacent to the punched part can be inserted, and The spare blade is characterized in that a part of the blade bulges out on one side of the blade body, a recess is formed on the other side corresponding to the bulge, and a punched part is bored in the bulge. Replacement blade.
