Description

[Detailed Description of the Invention] The present invention is an intermediate fulcrum type scissors in which when a closing operation is performed, one blade body slides toward the fulcrum in a sliding state, that is, = Generally, scissors are made of a pair of members consisting of a blade body and a solid body, which are crossed and the middle part is pivoted by a spindle, so when the blades are closed from the open state, the V-shaped intersection The cutting part gradually closes its angle and moves forward, so the material to be cut becomes less sharp due to the decrease in the closing angle and the force that tends to push it forward. .

This idea was created with this in mind! By sliding the single-strength blade of the pair of members toward the cross fulcrum during the pinching action during cutting, the knife does not simply cut the material to be cut. The purpose of this is to improve the cutting quality by simultaneously performing the cutting and pulling process, and this will be explained below with reference to the embodiments shown in the drawings.

In the figure, 1 and 2 are a pair of members constituting scissors,
Both blades 1 have thin blades 1' and z made of ceramic material, steel, super steel alloy, etc. attached to the opposing inner surface.
a, 2a and an individual 1 bs 2b, and these two members 1, 2 are pivoted by a spindle 3 in a crossed state near the base of the blade 1ay2a, and an individual 2ay2b with the spindle as a fulcrum. The blade body 1at1b is opened and closed by the opening/closing operation of the blade body 1at1b.However, one of the members 1 and 2 is integrally connected to the blade body 1a and the individual body 1tf by screws 4, etc. The member 2 has the base part of the blade body 2a interposed between the right and left parallel side plates 2c, 2c formed on the individual body 2b so as to have a U-shaped cross section, and the blade body 2a.
The insertion hole of the support shaft 3 formed in is made into an elongated hole parallel to the side plate 2c and long in the front and back, so that the blade body 2a can be slid back and forth with respect to the individual 2b. 2c
This is a guide hole formed in the front-back direction in the blade body 2a on the opposing side so that the protrusion l protruding from the inner surface of the tip can be loosely fitted therein.

Reference numeral 8 denotes a support on the upper half side of the longitudinal force axis X of the scissors from a protrusion 9 provided at the base end of one blade body 2a which is made slidable, and an individual body 1b integrated with the other blade body 1a. Axis 3
and the arm portions 10 formed in a shape approaching toward the pivot pins 1, respectively.
Both members 1 and 2 are connected by link pieces 1 and 12.
By transmitting the movement of the pivot pin 11 in the direction of the arrow a around the support shaft 3 metal when closing the pivot pin 12 to the other pivot pin 12 in parallel with the elongated hole 5, the blade body 2a' is It is slid backward between the plates 20.

Although the figure shows a state in which thin blades 1' and i made of ceramic material are attached to the inner surfaces of the members 1 and 20, they may be made of a single material like conventional scissors. In addition, there is no problem even if the arm portion 10 is formed on the blade body 1a.

The scissors having the above configuration have a blade body 1at1b as shown in FIG.
When the blade body is closed from the open state as shown in FIG. Therefore, the blade body 2a, which is interposed between the opposite side pieces 2c, 2c of the external force body 2b via the link piece 8, and in which the insertion hole 5 of the support shaft 3 is an elongated hole, slides in the direction of the arrow b. When the blade body 2a is moved, the blade body 2a receives the resultant force of the rotation about the 3-ft support shaft and the sliding movement, and cuts the material to be cut while cutting it. If this is further opened, the blade body 2a will be pushed back in the direction of the arrow, contrary to the above.

As described above, according to the present invention, in a row of scissors each having a blade body and an individual member, the scissors are pivotally connected to each other so that they can be opened and closed by using the supporting shaft sound in a metal cross shape, and one of the blade bodies and the individual member are integrally formed. In accordance with the continuous formation, the self-powering blade is interposed between both side plates parallel to the tip of the handle so that it can slide back and forth, and the shaft of the blade is An insertion hole is formed parallel to the side plate, and the pivot pin on the slidable blade base is located on one side of the longitudinal axis of the scissors passing through the support shaft, and the support shaft is the center of rotation. Since the pivot pin on the individual side of the force member is connected by a link piece, when the above-mentioned two members are closed, the blade body of one force interposed between the both side plates of the individual unit is connected to the blade of the other force. In addition to creating a pinching effect in relation to the body, the blade body is slid backward in the forming direction, and as a result, it pulls the material to be cut toward the support shaft during cutting, making it powerful. Moreover, it produces the effect of cutting with a light force.

In addition, when a thin blade made of ceramic material is attached to the inner surface of the opposing side of the double-edged body, the wear of the blade is drastically reduced and the cutting force can be made even stronger.
