Abstract

PURPOSE: To accurately cut even a deformative material, using scissors comprising a pair of opposing cutting blades, which have a part for controlling a horizontal movement of the material in one cutting blade and a part for controlling a vertical movement of the material near the part for controlling a horizontal movement of the material. CONSTITUTION: For cutting, for example, an edge corner 111 of a tape 110 using a pair of scissors 10, the corner 111 is inserted in a controlling space 18 and projected on the side of a corner cutting blade 14a between ribs 16 and 17, while sides 110a and 110b of the tape 110 are, respectively, contacted with controlling surfaces 16a and 17b of ribs 16 and 17, to thereby control a horizontal movement of the corner 111. In this case, the tape 110 is contacted with a contacting member 20 for controlling a height of an inner part of the controlling space 18, so that a vertical movement of the tape 110 is controlled. That is, curling of the tape 110 is prevented by means of a supporting member 19 and the contacting member 20. Thus, the tape 110 is smoothly guided by the ribs 16 and 17, so that the corner 111 is accurately cut by the corner cutting blade 14a.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a sandwich 10 which is an embodiment of the present invention has a pair of sandwiching pieces 12A and 12B which are rotatably connected to each other by a spindle 11. Fragment 1
Handles 13 are provided on the right portions of the drawings 2A and 12B, respectively. A pair of cutting blades 14 are provided facing each other on the left side of the flapping pieces 12A and 12B in the figure.

As shown in FIGS. 3 and 4, at the positions of the pair of cutting blades 14 on the side of the support shaft 11 in the longitudinal direction, the corner cutting blades 14a formed in an arcuate blade shape are complementary. Are provided so as to mesh with each other, and at a position on the opposite side thereof, that is, a position on the tip side of the cutting blade 14, a continuously formed corrugated blade-shaped side cutting blade 14b is complementarily meshed. It is provided in.

As shown in FIG.
As shown in, the guide 15 is provided at the same height as the cutting blade 14 so as to project outward from the cutting blade 14. On the guide 15, as shown in FIGS.
17 are provided so as to project at a predetermined interval, and a regulation space 18 is provided between the ribs 16 and 17 to cut the corner cutting blade 14.
It is formed at a position corresponding to a. And rib 1
On the restriction space 18 side of 6 and 17, restriction surfaces 16a and 17a are formed perpendicular to each other in a shape that matches the arcuate blade shape of the corner cutting blade 14a. Further, the rib 17 has a restriction surface 17b formed perpendicularly to the side cutting blade 14b. That is, the ribs 16 and 17 form a horizontal regulating portion.

As shown in FIG. 7, a supporting member 19 is provided on the ribs 16 and 17 so as to cover the regulation space 18 over the ribs 16 and 17, whereby the height of the regulation space 18 is increased. Are limited. Further, a contact member 20 having a predetermined thickness is fixed to the lower surface of the support member 19, and the height of the inner part of the restricted space 18 is further limited. In addition, the support member 19 has the extending portion 19a and the rib 1
It is provided so as to project from the regulation surface 17b of No. 7 to the side cutting blade 14b side. That is, the contact member 20 (or the support member 1)
9) and the guide 15 constitute a vertical movement restricting portion.

When the corner portion 111 at the tip of the tape 110 is cut into a round shape by using the above-mentioned sandwich 10, the corner portion 111 is inserted into the restricted space 18 as shown in FIGS. Then, the corner 111 is cut from between the ribs 16 and 17 to the corner cutting blade 1
The side portions 110b and 110a are brought into contact with the regulating surfaces 16a and 17a of the ribs 16 and 17 to regulate the horizontal movement of the corner portion 111 of the tape 110 while projecting to the 4a side.

At this time, the contact space 20 is provided by the contact member 20.
Since the height of the inner part of the tape is limited, the tape 110
The vertical movement of the tape 110 is also restricted in such a manner that the tape comes into contact with the contact member 20. That is, when the tape 110 is curled, the support member 19 and the contact member 20
Thus, the curl of the tape 110 is corrected. Therefore, the tape 110 is reliably guided by the ribs 16 and 17, so that the corner portion 111 to be cut can be easily cut at the corner cutting blade 14a.
The corner portion 111 can be cut quickly and accurately. On the other hand, since the vicinity of the entrance of the regulation space 18 is formed higher than the inner portion where the contact member 20 is provided, the corner portion 111 of the tape 110 can be easily inserted into the regulation space 18.

In addition, the side portion 1 of the tape 110 using the sandwich 10
When cutting 10b in the lateral direction, as shown in FIG. 6, the side portion 110c is brought into contact with the regulation surface 17b of the rib 17 to regulate the movement of the tape 110 in the horizontal direction. On this occasion,
The vertical movement of the tape 110 is also restricted so that the tape 110 contacts the extending portion 19a of the support member 19. Therefore, the tape 110 is reliably guided by the ribs 17, the portion of the tape 110 to be cut can be easily aligned with the side cutting blade 14b, and the tape 110 can be prevented from being cut obliquely. As described above, the ribs 16 and 17 and the support member 19 are the corner cutting blades 14a.
Since it is provided on the side, the tape 110 having various widths can be cut on the side cutting blade 14b side.

In the above-mentioned example, by fixing the separate contact member 20 to the lower surface of the support member 19, the vicinity of the inlet of the regulation space 18 is made higher and the inner portion is made lower, but it is constructed as follows. You can also That is, as shown in FIG. 8, the thick portion 19b may be integrally formed on the lower surface of the support member 19. Further, as shown in FIG. 9, the thick-walled portion 19b may be formed in a curved surface shape projecting downward toward the central portion, and in this case, the tape 110 can be further easily inserted into the regulation space 18. . Further, as shown in FIG.
6, 17, the support member 19 and the contact member 20 may be integrally formed.

Further, in the above example, the tape 1 in the regulated space 18 is fixed by the fixed member such as the support member 19.
Although the vertical movement of the tape 10 is restricted, the vertical movement of the tape 110 can be restricted by a movable member.

For example, in the example shown in FIGS. 11 and 12, the pressing member 21 has a pressing portion 21a formed of an elastic material in a hemispherical shape, and a hole 21b is formed in the center of the pressing portion 21a. Has been done. The pressing member 21 is fixed so as to straddle between the ribs 16 and 17, and the pressing portion 2
1a is arranged in the center of the restricted space 18. And
A lever 22 is rotatably provided on the rib 16, and a tip 22a of the lever 22 is arranged below the pressing portion 21a so as to project from the restriction surface 16a.

Therefore, when cutting the corners of the tape, as shown in FIG. 13, the pressing portion 21a of the pressing member 21 is projected downward in a hemispherical shape and is inserted into the regulation space 18. The surface of 110 is pressed from the upper side to regulate the vertical movement. That is, since the tape 110 is held by the elastic deformation of the pressing portion 21a, the tape 110 is held more reliably than the case of using the support member 19 and the like, and the tape 110 can be cut more accurately.

When the tape is again inserted into the regulation space 18, the lever 22 is tilted as shown in FIG. Then, the pressing portion 21a is connected to the tip 22 of the lever 22.
It is pushed up by a, elastically deforms and protrudes upward in a hemispherical shape, as shown in FIG. Therefore, the regulation space 18 becomes wider and the tape can be easily inserted. The tip of the lever may be pressed against the guide 15 via a spring so that the lever itself presses and holds the tape.

Further, in the above-mentioned example, the cutting edge shape of the side cutting blade 14b is a corrugated interdigitated blade shape formed continuously, but the cutting edge shape of the side cutting blade 14b is shown in FIG. 1
7, as shown in FIG. 18, a continuous rectangular shape,
It may have various interleaved blade shapes such as a U-shape, or may have a linear blade shape.
