Description

Detailed Description of the Invention (Industrial Application Field) The present invention is a replaceable blade type scissors in which the blade body and the scissors body are separate bodies, and the blade body is attached to the scissors body at the blade attachment part of the scissors body. This invention relates to an improvement in scissors that are fixed by being sandwiched from both sides, that is, scissors whose blade bodies are not completely exposed on both sides.

(Prior art) There have been scissors in the past where the blade is fixed by being sandwiched from both sides of the blade by the blade clamping plate of the scissor blade, but the blade is permanently fixed and cannot be replaced. I couldn't do it.

(Problems to be Solved by the Present Invention) An object of the present invention is to improve the conventional scissors described above so that the blade body can be replaced.

(Means for Solving the Problems) The present invention is characterized in that two scissors blades are swingable around a support shaft located in the middle thereof, and a scissor blade clamping plate of both scissors blades is provided in front of the support shaft. The blade is clamped between the scissors, and by swinging the scissors, the two blades intersect to perform a cutting action. The blade body is bent parallel to the blade edge so that the blade edge exposed from one side can come into contact with the other blade edge when the blade is clamped between the plates, and the blade body is bent at least against the blade surface. The scissors are formed by being biased by the thickness of the clamping plate on the inner surface of the plate, and there is an open opening in front of the clamping plate for inserting the blade, A slider is slidably inserted into the rear part of the blade insertion gap leading from the opening, and the finger rest of the slider protrudes outward from the slit between the clamping plates. That is.

Next, the configuration of the present invention will be explained with reference to the drawings showing examples.

Reference numeral 1 denotes a blade, and by providing a bent portion 2 in the longitudinal direction, a blade edge 4 is formed with respect to the blade surface including the upper edge 3.
is biased. The rib 5 having an arcuate cross section is used to smoothly insert the blade between the clamping plates 6 and 7 of the scissors.

The outer clamping plates 7, 7 are formed integrally with the scissors body, and the inner clamping plates 6, 6 are plate-shaped plates formed separately. Both clamping plates 6, 7 are glued together at adhesive surfaces 8, 9 on their respective sides. A slider 10 is slidably inserted between the two clamping plates 6 and 7, and its finger rest 11 protrudes outward from a slit provided at the joining portion of the two clamping plates. The slider is used to push the clamped blade forward a little, and then pull out the blade stuck out in front of the clamping plate. The sliding distance of the slider 10 is regulated by the loose fit between the protrusion 12 provided on the inner surface of the clamping plate and the recess 13 of the slider. The groove 14 having an arcuate cross section functions as a guide groove for the rib 5 of the blade body.

5 and 6 both show the inner clamping plate 6.
The longitudinal side edges 15 of the outer clamping plates 7 are set back toward the joining portion of the clamping plates 7, and FIG. The side edges 15 and 16 are aligned.

The present invention has the above configuration, and the cutting edge exposed from one side of the blade clamping plate is placed close to the other scissors with respect to the blade surface, and at least the inner surface of the blade clamping plate is clamped. Since the plate is biased by the thickness of the plate and comes into contact with the cutting edge of the other blade, there is no possibility that only the inner surfaces of the blade clamping plates will come into contact with each other and the cutting action will not be possible. Furthermore, since the blade is sandwiched from both sides, the blade is reinforced, and the blade can be made as thin as a safety razor, making it possible to provide sharp scissors.

(Operations and Effects) In the present invention, there is an open opening for inserting the blade in front of the clamping plate, and a slider is slidable at the rear of the gap for inserting the blade that communicates from this opening. The slider finger rest protrudes from the slit between the two clamping plates. Therefore, the blade can be inserted and attached through the open opening. Also, when replacing the blade with a new one, slide the slider 10 forward and let the front end of the blade protrude a little from the opening, then you can pinch that part with your fingers and pull it out. The body can be inserted and replaced.

Conventional scissors of this type could not have their blades replaced, but with the present invention, the blades can be replaced easily, allowing you to easily replace blades that have lost their sharpness, allowing you to use scissors that are always sharp. Can be used.

Claims (1)

[Claims] 1. The two scissor blades are capable of swinging around a spindle located halfway between them, and the blade bodies are clamped between the blade body clamping plates of both scissors blades in front of the spindle, allowing the scissors to swing. By moving the blades, the blades intersect to perform a cutting action, and the blades are sandwiched and fixed from both sides by the blade clamping plates, and exposed from one side when clamped by the blade clamping plates. Bend the blade parallel to the blade edge so that the blade edge can contact the other blade edge. The scissors are formed so as to be biased by the thickness, and there is an open opening for inserting the blade in the front of the clamping plate, and a rear part of the blade insertion space that communicates from the opening. A replaceable blade type scissors characterized in that a slider is slidably fitted into the scissors, and a finger rest part of the slider protrudes to the outside from a slit between both clamping plates.
