【Example】

 A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows a state in which the scissors body 2a of the slide-operated scissors 1a has its cutting edge closed, FIG. 2 shows a state in which the scissors body 2a is squeezed into the grip case 3a, and FIG. The inner part of the slide-operated scissors 1a is shown. As shown in FIGS. 3 and 4, the grip case 3a of the slide-operated scissors 1a has a structure in which the upper case 4 and the lower case 5 are divided into two, and is formed to be slightly flat. The upper and lower cases 4, 5 are provided with guide portions 4a, 5a having a shape shown in the drawings, and Japanese scissors-shaped scissors 2a are mounted on the guide portions 4a, 5a slidably in the longitudinal direction. Narrow slits 4b, 5b and openings 4c, 5c wider than the slits 4b, 5b are formed at the tips of the upper and lower cases 4, 5, and the scissors 2a is opened from the openings 4c, 5c. The cutting edge can be projected (see Fig. 1).

Further, as shown in FIGS. 4 and 5, a dovetail-shaped slide groove 4 d is formed on the upper surface of the upper case 4, and a long hole 4 e communicating with the guide portion 4 a is formed on the bottom surface of the slide groove 4 d. It extends parallel to the slide groove 4d. A slender pusher 6 having a substantially trapezoidal cross section is slidably fitted in the slide groove 4d. As shown in FIG. 6, the pusher 6 has a rear end portion which holds the base end portion of the scissors body 2a. A gripping claw 6a is provided so as to project, and an unevenness for slip prevention is formed on the upper surface of the pusher 6. That is, the pusher 6 is connected to the scissors body 2a through the grip claws 6a penetrating the elongated hole 4e.

Now, when using the slide operation type scissors 1a having the above-mentioned configuration, as shown in FIG. 7, the grip case 3 is grasped and the pusher 6 is slid forward with the thumb. Then, the scissors body 2 a moves forward following the pusher 6 and projects from the grip case 3. At this time, the scissors body 2a is in sliding contact with the guide portions 4a and 5a, so that its posture is restricted, and the blade tip is opened at the beginning of protrusion, but the blade tip is completely closed when the protrusion is finished. (See Figure 1). Since the scissors body 2a is biased in the open state similarly to the Japanese scissors, the cutting edge of the scissors body 2a can be opened and closed by simply sliding the pusher 6 back and forth. Therefore, with the slide-operated scissors 1a of the present embodiment, unlike the conventional scissors, it is not necessary to open and close the action point of the scissors with the fingertips, and the cutting work can be performed simply by sliding the pusher 6 forward with the thumb. Can be done quickly and safely. At this time, the slits 4b and 5b serve as guides for supporting the object to be cut substantially perpendicularly to the blade surface. Moreover, since the grip case 3 is formed in a flat shape, for example, it is easy to insert it obliquely between the bandage and the skin to cut the bandage, and there is no risk of damaging the skin.

Next, a second embodiment will be described. As shown in FIGS. 8 and 9, the grip case 3b of the slide-operated scissors 1b is provided with a guide portion 7a having the illustrated shape, and the scissors body 2b is attached to the guide portion 7a so as to be movable back and forth. There is. The scissors body 2b is rotatably formed around the support shaft 8a, and is connected to the connecting rod 8c while being biased in the opening direction by the spring 8b. The connecting rod 8c can be moved back and forth within the grip case 3b, and the rear end portion of the connecting rod 8c is slidably engaged with an elongated hole 7b formed in a side portion of the grip case 3b. It is connected to 9. The guide portion 7a has a narrower width toward the tip so that the scissors body 2b in sliding contact closes the cutting edge, and a slit 7c that can expose the cutting edge of the scissors body 2b is formed.

In the slide-operated scissors 1b having the above structure, when the pusher 9 is slid forward with a finger, the scissors body 2b exposes the cutting edge from the slit 7c and is inserted into the guide portion 7a to close the cutting edge ( When the pusher 9 is slid rearward with a finger, the scissors body 2b opens the cutting edge by the spring 8b (see FIG. 9). Therefore, the object to be cut inserted in the slit 7c can be cut by a one-touch operation.

Next, a third embodiment will be described. In the slide-operated scissors 1c shown in FIG. 10, a guide portion 10a having the illustrated shape is provided at the tip of the grip case 3c, and a slit 10b extending in a direction orthogonal to the sliding direction of the pusher 9 is formed in the guide portion 10a. . A pair of blades 11a and 11b of the scissors body 2c attached to the guide portion 10a are connected by a support shaft 11c, and are biased in the opening direction by a spring 12 so that the blade tip faces the slit 10b. It has become. Then, one blade 11a is in contact with the guide portion 10a and is not rotatable, and the other blade 11b is connected to the connecting rod 13 so that the linear movement of the connecting rod 13 can be converted into the rotational movement of the blade 11b. It has become. The rear end of the connecting rod 13 is connected to the pusher 9, and the pusher 9 is engaged with the elongated hole 10c formed in the side portion of the grip case 3c so as to be slidable back and forth.

Therefore, in the slide operation type scissors 1c of the present embodiment, the scissors body 2c can be opened and closed by sliding the pusher 9 with a finger, as in the above-described embodiments, and the scissors body 2c is inserted into the slit 10a. The object to be cut can be cut.

Next, a fourth embodiment will be described. As shown in FIG. 11, a slit 14 is formed at the tip of the grip case 3d, and the scissors 2d is attached to the grip case 3d via a support shaft 15 so as to be openable and closable. The scissors body 2d is urged by the spring 16 to open the cutting edge. As shown in FIG. 13, the pusher 18 is slidably mounted in the slide groove 17 of the grip case 3d. When the pusher 18 is slid forward, the pusher 18 has the tip portion 18a of the pusher 18 after the scissors 2d. The abutting portion at the end is pushed and expanded to close the cutting edge of the scissors body 2d.

Therefore, in the slide-operated scissors 1d of the present embodiment, the object to be cut inserted in the slit 14 can be cut by sliding the pusher 18 with a finger as in the above-described embodiments. it can.

Next, a fifth embodiment will be described. The slide operation type scissors 1e shown in FIG. 14 has substantially the same structure as the slide operation type scissors 1a of the first embodiment described above, but is provided with a pusher 19 formed in an L shape by an elastic member such as rubber. The pusher 19 can slide in a state in which the pusher 19 is in close contact with two adjacent surfaces of the grip case 3e (in this case, one is a curved surface). Therefore, the slide-operated scissors 1e can be easily slid regardless of whether it is used vertically or horizontally.

Next, a sixth embodiment will be described. In the slide operation type scissors 1f shown in FIG. 15, the mounting position of the pusher 20 is changed as compared with the slide operation type scissors 1a of the first embodiment. That is, the slot 22 and the slide groove 23 are provided on the outer peripheral surface (the upper surface in the figure) that is substantially orthogonal to the surface of the grip case 3f on which the slit 21 is formed. The pusher 20 that slides along the slide groove 23 is connected to the base end portion of the scissors body 2f so that the scissors body 2f slides into a guide groove (not shown). The upper surface of the pusher 20 is a curved concave surface so that it can be easily operated with a finger.

Next, a seventh embodiment will be described. As shown in FIG. 16, a scissors body 2g including a stationary blade 30 and a moving blade 31 is connected to a first pusher 33 via a support shaft 32, and a slide groove 34 provided in a grip case (not shown). You can slide inside. A second pusher 33a is slidably mounted on the first pusher 33 in the sliding direction of the first pusher 33, and a hemispherical projection 33b formed on the lower surface of the second pusher 33a is formed on the back surface of the moving blade 31. It abuts against the abutting portion 31a. That is, this abutting portion 31a constitutes a cam surface having the shape shown in the figure, and when the protrusion 33b slides on the cam surface, the moving blade 31 rotates around the support shaft 32 accordingly. It has become. Although not shown, the grip case is formed substantially the same as the grip case 3f of the sixth embodiment, and the first pusher 33 slides along the long hole formed in the grip case. The positional relationship (relative sliding) between the first pusher 33 and the second pusher 33a, which are formed so as to be capable of engaging with each other, is controlled by the shape of the elongated hole. That is, when the scissors body 2g slides to the tip position of the grip case, the portion of the elongated hole corresponding to the second pusher 33a at that position is formed wider than the other, and the elastic deformation is caused by the wide portion. The enabled second pusher 33a is disengaged from the first pusher 33 and is configured to be slidable relative to the first pusher 33.

Therefore, in the slide operation type scissors 1g having the above structure, first, the first pusher 33 is slid to expose the blade edge of the scissors body 2g from the grip case, and then the second pusher 33a is further slid. Then, referring to FIG. 16B, since the contact portion 31a is pushed by the protrusion 33b, the moving blade 31 is rotated and the scissors body 2g is closed. After use, if the second pusher 33a is pulled toward the first pusher 33, the moving blade 31 rotates in the opposite direction. After that, the first pusher 33 is slid to grasp the scissors body 2g and store it in the case.

It is needless to say that the present invention can be implemented in a mode in which various modifications are made based on the knowledge of those skilled in the art in addition to the first to seventh embodiments described above.
