[0006]

Embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 3, the shape of the claw 1 of the remover extending from the base end of the stapler to the extension of the lower surface of the stapler is a spade type of a playing card. The width is gradually increased in the direction, the width of the widest part is substantially equal to a predetermined distance between the needle legs, the base is formed in a flat rectangular surface in the base direction, and the vicinity of the base is sharply narrowed.

In FIG. 1 and FIG. 2, the tip of the rectangular portion of the widest part of the nail 1 is used as a nail base 2, and the center of the nail is cut vertically into a U-shape except for both sides of the nail 1. A rectangular child nail 3 is raised in the direction opposite to the nail 1 at an inclination angle of about 20 degrees with respect to the nail in the axial direction of the stapler. A first structure (FIG. 1) in which the height of the tip of the child nail from the lower surface of the nail is lower than the height of the needle leg, and a second structure in which the tip of the child nail extends to a height higher than the height of the needle foot (FIG. 7) ).

When forming the nail base, as shown in FIG. 2, an iron plate 5 to be fixed to the base 4 of the stapler to form a nail at the end is formed in a central portion near the base end. The curved portion 9 is raised and curved to have the same thickness as the base of the claw, and the angled curved portion is extended downward to the same plane as the lower surface of the base, and the claw is formed forward on the plane. In that step, either side is cut out while leaving the chevron, or the part to be cut out is bent to the back of the chevron.

In forming the nail on the nail, in order to prevent the needle from being pulled up at the narrow width of the nail when the needle is pulled out and to bend the paper due to bending and bending, the width of the nail is almost equal to the distance between the needle legs. It is best to use the front side of the nail rectangular part as the root of the nail and raise the nail therefrom.

Both legs 6a and 6 standing upright on the iron plate 5
b and a loop-shaped needle storage ring 8 made of a plate material of an elastic material having a width tightly fitted between the two supporting leg sides in a space A limited by a spring or a spring 7 pressing the leg. As shown in FIGS. 4 (A) and 4 (B), the center of one side edge of the storage ring is locked at the lower end of the chevron, and both sides of the storage ring are base up to the base lower surface. Extending to the end, the locking bend 8
Make one. The other side of the storage ring is a storage ring upper side 82,
Spread on the upper surface of the nail. In the first structure in which the tip of the nail is lower than the needle leg (FIG. 1), it is a principle that the upper side of the storage ring extending to the upper surface of the nail does not exceed the height of the needle on the upper surface of the nail. It is sufficient to provide a gap through which the needle can pass between the upper surface of the nail and the upper side of the storage ring. In the second structure (FIG. 7) in which the tip of the nail is extended to be higher than the needle leg, the tip of the upper side of the storage ring is formed as a tongue piece 83, and the tongue piece is pressed against and attached to the upper surface of the nail. In that case, the edge of the tongue piece is slightly warped upward.

With the above construction, when the elastic loop-shaped storage ring is fitted into the empty portion A, the storage ring is closely fitted between the two sides of the support legs and pressed between the support legs. The base side of the storage ring is locked by the angled curved portion, and the storage ring is vacant A
Will be installed inside. The nail of the remover is inserted between the needle and the paper, and as the remover is pushed forward, the needle 13 gradually moves along the inclination of the child nail 3 as shown in FIGS. Pulled up from paper and pulled out. At this time, the nail is raised from the maximum width of the nail, which is almost the same as the distance between the needle legs, so that as the nail is pushed, the paper is pressed flat under the nail, which is almost equal to the needle width. Until the bent portion of the needle is bent to the width of the nail and pulled out, it is possible to prevent the paper from bending and bending and thereby damaging the paper. In the case of the first structure, the upper side of the needle enters the lower side of the upper side of the storage ring with the advance of the rim bar, and even if the needle is pulled out vigorously, the upper side of the storage ring and the lower side of the lower side of the lower claw upper needle leg may be moved. It is blocked by the side, and scattering of the needle is prevented. Normally, the needle is not completely removed from the paper, and can be removed by hooking the upper side of the needle between the nail and the nail. Since the upper side of the storage ring was extended with a gap through which the upper needle of the nail can pass, when the tip of the remover was raised,
Since the drawn-out waste needle does not hinder falling and the needle leg does not get caught on the base of the thin nail as shown in FIG. 5 (C),
Fall into the storage ring.

In the case of the second structure (FIG. 7), the upper side of the needle is pressed between the upper surface of the nail and the tongue 83 to which pressure is applied by the upper side 82a of the elastic storage ring as the remover advances. Since the needle is pulled out in a state where the needle is drawn, both legs of the needle are pulled out even if there is a front and back. When the upper side 82a of the storage ring is pushed open, the space between the upper surface of the nail and the tongue 83 is opened, and the needle can be dropped and stored in the storage ring by raising the rim bar. It is preferable that a part of the upper side is formed slightly wider so that the upper side of the storage ring can be easily pushed with a finger.

As shown in FIG. 6, a storage ring lid 84 is provided between the two supporting leg side portions 6a and 6b, which is always closed, and extends outside the side portion 6a and 6b. The storage ring lid 84 is attached to the storage ring side by utilizing the elasticity of plastics or the like so that the lid can be opened and closed at any time by pushing up the lid side 84a. When storing the waste needle, the storage ring lid 84 is opened, and after storing, the storage ring lid 84 is closed to prevent the needle from falling off. If the magnet 11 is attached to the bottom of the storage ring, the storage needle lid 84 does not need to be provided, and the waste needle can be adsorbed to prevent the needle from falling off.

When discarding the waste needle, the storage ring locking bent portion 81
Is pushed up, one side of the storage ring locked by the chevron 9 is released from the lock, and when the upper side of the storage ring is pulled, the entire needle storage ring can be removed, so that the needle can be easily discarded. .

Thereafter, the storage ring can be easily mounted by pushing the storage ring into the empty portion A and locking it at the angled curved portion. Since the storage ring is locked to the angled curved portion by the urging force expanding outward, the storage ring does not come off from the empty portion even if the legs rotate and are pushed by the spring. The chevron of the iron plate also serves to strengthen the base of the nail.

An embodiment of another embodiment according to the present invention will be described with reference to FIG. A scoop-shaped blade is provided at the end of the base of the stapler, and both sides of the blade are curved and protruded, and the upper edge 1a of the blade is formed with a constant inclination angle of about 20 degrees from both sides of the blade tip. Formed and lowered to the base end before the height of the upper edge reaches the height of the needle. The distance between the upper edges on both sides at the top of the upper edge is slightly smaller than the distance between the needle legs. The upper edge of the blade base forms a base locking portion 85 which rises at an acute angle from the base end. It is desirable to form the blade base 14 from the uppermost end to the base end with a small width as shown. A cut 1c at which the upper side of the needle can be hooked is provided at a position past the highest point on both upper edges.

A loop-shaped storage ring 8 made of a resilient plate material is fitted into a space between the pivots of both legs of the stapler and the base, and the base side edge of the storage ring is closed. The blade is locked to the blade base locking portion 85, and the side of the storage ring opposite to the base is extended above the front upper edge of the blade, and the front upper edge is higher than the uppermost edge of the blade. Above, in principle, the upper edge of the storage ring does not exceed the height of the upper needle on the blade upper edge, but preferably, there is a gap between the upper edge of the blade and the upper edge of the storage ring through which the needle can pass. It is enough.

With the above construction, the tip of the blade of the remover is inserted between the needle and the paper, and as the remover is pushed forward, a constant inclination angle of about 20 degrees from the tip of both sides of the blade is obtained. As shown in FIGS. 9 (A) and 9 (B), the needle is gradually pulled up from the paper surface along with the inclination of the upper edge of the blade which does not reach the height of the needle, and the paper 12 is attached to the bottom surface of the blade. The needle comes out while bending slightly. In the case of the instep structure, since the needle leg is not completely removed from the paper, the needle can be completely removed by hooking the upper side of the needle with the cut 1c and pulling it. Even if the needle which has entered the lower part of the storage ring with the advance of the rim bar may come off vigorously, scattering is prevented by the upper edge of the storage ring and the curved ridge of the blade. When the tip of the remover is raised, there is a gap between the upper edge of the storage ring and the upper edge of the blade, through which the needle can pass, so that the upper edge of the needle is not obstructed. Fig. 9
As shown in (C), the base of the blade is thin and falls into the needle storage ring without being caught.

As shown in FIG. 6, a storage ring lid 84 which is always closed between the two sides of the support legs is provided inside the middle of the upper side 82 of the storage ring, and extends outside the side edges 6a and 6b of the support legs. The lid 84 is provided on the storage ring by utilizing the elasticity of plastic or the like so that the lid 84 can be opened and closed at any time by pushing up the lid side 84a. As in the previous embodiment, the lid 84 is opened when storing the waste needle, and closed after storing the waste needle to prevent the needle from falling off. If the magnet 11 is attached to the bottom of the storage ring, there is no need to provide the storage ring lid 84,
It is the same as in the above embodiment that the waste needle can be adsorbed to prevent the needle from falling off.

When discarding the waste needle, a method of removing the storage ring, a method of attaching and detaching the storage ring, and a state that the storage ring is locked by the blade base locking portion 85 so that the storage ring does not come off due to rotation of the leg or the like. , Are the same as in the previous embodiment.

The case of the second party structure will be described with reference to FIG. Extend the upper edge of the blade until it is higher than the needle foot, then lower it to the end of the base. The tip of the upper side 82a of the storage ring is formed as a tongue side 83, and the upper edge of the blade is pressed against the upper edge from the highest edge to the tip of the upper edge of the blade, and the side edge is slightly bent upward. .

With the advance of the remover, the upper side of the needle is
Since it enters between the upper edge of the needle and the tongue piece 83 and is pulled out of the paper in a state of being sandwiched and pressed by both, both legs of the needle are pulled out even if there is a front and back. When you push up the storage ring,
The space between the upper edge of the blade and the tongue piece 83 is opened, and the needle can be dropped and stored in the storage ring by raising the remover. Providing a storage ring lid 84 or attaching a magnet 11 to the bottom of the storage ring to prevent the needle from falling out, a method of attaching and detaching the storage ring, and a method of discarding waste needles.
It is the same as the case of the instep structure.

[0023]

As a major effect of the present invention, a single stapler is provided with an attached rim bar and a needle accommodating ring. Therefore, there is no inconvenience of using a rim bar separate from the stapler, and a waste needle can be used. Eliminating the trouble of throwing them away into waste baskets and other items eliminates the danger of discarding waste needles. Regarding needle removal, needle removal requires the removal of the needle with a single remover claw by applying a force to raise the claw upward, which also causes the needle to fly. Then, by simply pushing the remover forward, the needle naturally comes off due to the slant of the nail or blade. The needle that has come out halfway can be hooked into the notch and pulled out. By pressing the upper edge of the nail or blade with the tongue on the upper side of the storage ring, only one of the needle legs is prevented from coming off. Regarding the accommodating of the staples and the processing of the waste staples, in the embodiment in which the nail is provided with the nail, and in the embodiment in which the spade blade is used, since the base is made thin, the tip of the stapler is raised. Simply or by pushing the upper edge of the storage ring to spread the tongue and raising the tip of the stapler, the waste needle falls into the storage ring without being caught in the middle and is easily stored. Describing the effect of each embodiment of the invention, in the embodiment in which the nail is provided with the nail, the lower surface of the nail is approximately the same width as the distance between the needle legs, so as the nail is pushed forward,
The paper is still pressed and supported by the lower surface of the nail, and the legs of the needle are spread and pulled out, thereby preventing the paper from bending and thereby damaging the paper. In the embodiment using a scoop-shaped blade, the legs of the needle are expanded according to the bending of the lowermost surface of the paper pressed by the curved bottom surface, so that the needle can be smoothly removed with a small force. .
