  Now, until now, the bag has been twisted slightly when opened. This twist is something that can only be felt by professionals such as barbers and hairdressers, but the more professional, the more the twist of the heel half affects the cutting work, A solution was sought.

  Therefore, the problem to be solved by the present invention is to solve the subtle twist of the heel half that has occurred during the cutting work by the heel.

The above-mentioned problems have been studied with eagerness. As a result, it has been found that the twisting of the saddle half is particularly caused by the narrow width (length x from the blade end to the flange end) of the flange.
That is, when the heel is closed, the overlapping area of the heel right half 20a and the heel left half 20b is relatively large regardless of the width of the heel. However, when the heel is open as shown in FIG. 1, the overlapping area of the heel right half 20a and the heel left half 20b is significantly smaller. By the force of the screw 24 against the overlapping portion, the twist of the heel is suppressed. However, when the heel is opened, the width of the heel is narrowed. When the heel is opened, the distance L from the position of the screw 24 to the farthest position P where the heel right half 20a and the heel left half 20b are overlapped. It will be shorter. Then, since the moment of torsional resistance is a function of the distance L, it has been found that the small distance L caused a slight twist during the cutting of the ridges, and was bothering the cutting professionals. .

  The present invention has been achieved based on the above findings.

That is, the above problem is
In the heel where the right half and the left half are connected by a connecting member,
Convex on the heel side of the heel right half and the heel left half in a region on the rear end side of the connection point by the linking member and in a region where the heel right half and the heel left half overlap. Ri name and part is provided,
The convex part of the right half has a sliding surface extending from the sliding surface of the right half that is in sliding contact with the left half,
The convex part of the left half of the heel has a slidable contact surface extending from the slidable contact surface of the left half of the heel in sliding contact with the right half of the heel,
During the opening operation of the heel, the sliding contact surface of the convex portion of the right half of the heel is slidably contacted with the sliding contact surface of the left half of the heel, and the sliding surface of the convex portion of the left half of the heel is The problem is solved by a bag characterized in that it is configured to be in sliding contact with the sliding surface of the body .

  Further, in the above-mentioned scissors, the convex portion is provided in a region farthest from the connection point by the connecting member in a region where the right half and the left half are overlapped. Solved.

  The kite configured as described above has a distance L from the position of the connecting member (screw) connecting the kite right half and the kite left half to the farthest overlapping position of the kite right half and kite left half. Is getting longer. Accordingly, the moment for twisting increases as the distance L increases, and twisting is less likely to occur. In addition, it is preferable that the convex part of this invention is provided in the farthest area | region from the connection point by a connection member in the area | region where the right half body and the left half body overlap.

  Even if the convex portion according to the present invention is provided only on one half, a significant effect is obtained. However, a larger effect can be obtained by providing the halves on both sides.

  Also, by providing the convex part not only on the heel side but also on the opposite side of the heel side, the convex part provided on the right half of the heel and the convex part provided on the left side of the heel are mutually closed when the heel is closed. It becomes more preferable because it becomes overlapped, and it becomes difficult for foreign matter to be caught between the convex portions.

  The bag of the present invention may be a general bag, but is particularly a barber or beauty salon. That is, in view of the effect of the present invention, it is a barber or beauty salon that has a great influence on the cutting condition even with a small twist. This kite is a kite in which the right half and the left half are connected by a connecting member (for example, a screw). And, the region on the rear end side from the connection point (fulcrum) by the connection member (screw) (the side opposite to the cutting edge side (tip side)), and the region where the right half and the left half overlap each other (Especially, for example, as shown in FIG. 1, in the state where the eyelid is large (near 90 °), the eyelid right half and the eyelid left half overlap each other) A convex portion is provided on the heel side of the half body. Preferably, it is provided not only on the heel side but also on the opposite side (blade edge side). That is, the convex portions are provided so as to be symmetric with respect to a center line passing through the fulcrum (screw) and the tip. The convex portion is a convex portion having a surface along the sliding contact surface between the right half and the left half. That is, the right half and the left half are in sliding contact with each other even on the surface of the convex portion. Preferably, the convex portion is provided in a region farthest from the connecting point by the connecting member in a region where the right half and the left half overlap.

FIG. 1 is a perspective view of a bag according to an embodiment of the present invention.
In FIG. 1, 1a is a right half body. This right half body 1a includes a blade body 2a, a handle portion 3a, and a finger ring portion 4a. 1b is the left half of the heel. The left half 1b has a blade body 2b, a handle portion 3b, and a finger ring portion 4b. The right half 1a and the left half 1b are connected to each other by the screw 5. This is because the blade body 2a and the blade body 2b overlap each other in most of the areas when the ridge 1 is closed, and the blade body 2a and the blade body 2 are opened when the ridge 1 as shown in FIG. 1 is opened. The body 2b overlaps only in a part of the region (region in the vicinity of the screw 5). In addition, since such a structure is general, detailed description is abbreviate | omitted.

  Reference numeral 6 denotes a slippery sheet (slidable plate) having a slipperiness provided on the inner surface of the left half half 1b (sliding contact surface with the right half half 1a). The sliding plate 6 is formed in a groove formed on an inner surface (sliding contact surface with the right half 1a) closer to the handle 3b (rear end side) than the position of the screw 5 in the left half 1b. It is embedded. In particular, the slipper plate 6 is so arranged that the surface of the slipper plate 6 becomes a slidable contact surface even when the scissors are greatly opened as shown in FIG. Even in the region where 1b overlaps, it is provided at the position of the farthest region from the position (fulcrum) of the screw 5. In addition, the sliding board 6 is formed in the circular arc shape (doughnut shape) centering on the position of the screw 5. FIG. Of course, it may be fan-shaped or other shapes. Although not shown, a sliding plate is also provided on the sliding surface of the right half 1a so as to face the sliding plate 6 provided on the sliding surface of the left half 1b.

  7a and 7b are substantially triangular convex portions provided on the heel side and the blade edge side of the right half body 1a. The convex portions 7a and 7b are provided so as to be exactly on the extension of the arc of the sliding plate. The arc-shaped sliding plate is also embedded in the inner surfaces (sliding contact surfaces) of the convex portions 7a and 7b.

  8a and 8b are substantially triangular convex parts provided on the heel side and the blade edge side of the heel left half 1b. The convex portions 8 a and 8 b are provided so as to be on the extension of the arc of the sliding plate 6. As can be seen from FIG. 1, the arc-shaped sliding plate 6 is also embedded in the inner surfaces (sliding contact surfaces) of the convex portions 8a and 8b.

  Now, even if the scissors configured as described above are opened widely as shown in FIG. 1, the convex part 7a of the scissors right half 1a and the convex part 8a of the scissors left half 1b are in sliding contact. Further, the overlapping area of the right half 1a and the left half 1b is large only by the convex portions 7a and 8a. Even at a position far from the screw 5, the right half 1a and the left half 1b are in sliding contact with each other. Therefore, the resistance against twisting of the right half half 1a with respect to the left half half 1b increases, and twisting is difficult to occur when the collar is opened, and the workability of cutting is improved.
