Description

  The present invention relates to a kite, a kite to be used as a general barber.

  A stationary blade side blade body superimposed on the lower side of the moving blade side blade body at the blade edge portion and a rod that pivotally attaches the moving blade side blade body at an intermediate portion are known without specific examples. .

  In the conventional example (in the barber), the blade edge of the moving blade side blade body is pressed so that the handle portion of the moving blade side blade body is pressed below the handle portion of the stationary blade side blade body during use (during cutting operation). Although the cutting part is more reliably rubbed against the blade edge part of the stationary blade side blade body to improve the cutting effect, many of the existing ridges are for the right hand, and when using with the left hand, the above pressing operation Requires proficiency through appropriate training.

  The present invention was devised to provide a kite that can be expected to have a cutting effect without requiring such proficiency.

  At the intermediate portion, the pressing member is placed at a position intersecting with the handle portion of the moving blade side blade body at the handle portion of the stationary blade side blade body pivotably attached to the intermediate portion of the moving blade side blade body and the connecting shaft. The pressing member is provided with a biasing means for pressing the handle portion of the moving blade side blade body in the direction of separating from the handle portion of the stationary blade side blade body along the axis of the connecting shaft. The configuration is as follows.

  According to the present invention, during use, the handle portion of the moving blade side blade body is pressed in a direction in which the pressing material separates from the handle portion of the stationary blade side blade body along the axis of the connecting shaft. An effect similar to that of pressing the handle portion of the blade body with a fingertip can be expected. Therefore, the blade edge portions of the two blade bodies can be more reliably rubbed together to provide a ridge having an excellent cutting function. Further, since the fingertip can be pressed lightly, it can be used as a wrinkle for correcting a wrinkle that is excessively pressed.

  FIG. 1 is a plan view, FIG. 2 is a cross-sectional view taken along the line 1a-a, FIG. 3 is a cross-sectional view taken along the line 1b-b, and FIG. FIG. 5 is a partially cutaway front view of the pressing member, FIG. 6 is a plan view of the second embodiment, and FIG. 7 is an enlarged sectional view of FIG.

  In the scissors according to the present invention, the blade edge portions 1a, 2a and the handle portions 1b, 2b are formed such that the blade edge portion 1a of the moving blade side blade body 1 and the blade edge portion 2a of the stationary blade side blade body 2 overlap (rub against) each other. And pivotally connected to each other by the connecting shaft 3 at the intermediate portion, and to the handle portion 2b of the stationary blade side blade body 2, the handle portion 1b of the moving blade side blade body 1 when using a scissors (when operated). The pressing member 4 is projected at a position intersecting with the pressing member 4 and pressing means is applied to the pressing member 4 to move the handle portion 1b of the moving blade side blade body 1 from the handle portion 2b of the stationary blade side blade body 2. The cutting edge is urged along the connecting shaft 3 and an external force acts in the direction in which the cutting edge portion 1a side of the moving blade side blade body 1 is in contact with the cutting edge portion 2a of the stationary blade side blade body 2 due to the pressing force. The parts 1a and 2a are rubbed with each other reliably, and the cutting performance is improved.

  In the first embodiment shown in FIG. 1 to FIG. 5, the pressing material 4 is separated from the stationary blade side blade body 2 of the heel A, and the pressing material 4 is detachably attached to the handle portion 2b. On the other hand, the present invention can be applied.

  In the pressing material 4 of the first embodiment, a receiving piece 5 is provided on the mounting base 4A ′ of the pressing material main body 4A, and a locking piece 9 at one end is locked to the receiving piece 5 to thereby attach the mounting base. Between the holding piece 6 and the mounting base 4A 'superimposed on 4A', one half is engaged with the mounting base 4A 'side, and the other half is engaged with the holding piece 6 side to be bent. The urging piece 7 is interposed, and the handle portion 2b of the stationary blade side blade body 2 is engaged with the opposed grooves 8 and 8 of the urging piece 7 when bent. The handle portion 2b is interposed between the attachment base portion 4A 'and the holding piece 6 and penetrates to the other end side of the holding piece 6 facing the one end on the side of the locking portion piece 9 locked to the receiving piece piece 5. The screw portion of the tightened screw 10 is screwed and fastened to the mounting base portion 4A ′, and as described above, is protruded from the handle portion 2b of the stationary blade side blade body 2.

  The contact edge 4 ′ of the pressing material main body 4 </ b> A of the pressing material 4 with the handle portion 1 b of the moving blade side blade body 1 is a turning locus of the moving blade side blade body handle portion 1 b around the connection shaft 3 ( As a result, the handle portion 1b rotates while being pressed against the contact edge 4 ', that is, the pressing member 4, by the action of the urging piece 7, that is, while being pressed. An external force acts in the direction opposite to the pressure receiving direction of the handle portion 1b on the blade edge portion 1a side, and the blade edge portion 1a is reliably rubbed against the blade edge portion 2a of the stationary blade side blade body 2 so that the blade edge portion 1a. , 2a, the article is smoothly cut.

  The contact edge 4 'is configured by embedding a hard resin piece 4'A in a metal pressing material main body 4A.

  The pressing member 4 of the second embodiment shown in FIGS. 6 and 7 is formed by projecting the base portion integrally with the handle portion 2b of the stationary blade side blade body 2, and the contact edge 4 ′ referred to in the first embodiment. The resin-made contact piece 4′A constituting the first engagement member is engaged with the recessed groove 12 provided in the pressing material main body 4A, and a coil spring 13 is interposed between the contact piece 4′A and the main body 4A to make the first. This is an urging means in place of the urging piece 7 (which may be made of an elastic resin) of the embodiment.

  In the case of the second embodiment, the contact piece 4'A presses the handle portion 1b of the moving blade side blade body 1 by the urging of the coil spring 13, and the cutting edge portion receives the action in the opposite direction to the handle portion 1b by the pressing. On the 1a side, a cutting operation is carried out by rubbing the blade edge portions 1a, 2a as close to the blade edge portion 2a of the stationary blade side blade body 2 as in the first embodiment.
