Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stapler.

[0002]

2. Description of the Related Art As is well known, a stapler is a kind of paper binding device, and when a lever is pressed, a U-shaped staple is
It is one that is launched individually. Most of them were stationary in the early days, but in recent years, portable ones that are small enough to fit in one hand have become popular.

[0003]

Generally, the stapler has an elongated shape having a length dimension corresponding to the extension length of the lever. When not in use, the stapler is often laid down on a tabletop or the like.
However, an elongated shape occupies a large space in a plane when it is laid down, which is not preferable.

Further, for a user who uses a stapler, a person who holds the little finger as shown in FIG. 5 and pushes the lever while holding the little finger on the tip side, and a thumb as shown in FIG. Some people hold it and press the lever to attach it. That is, the directions of use are different for each user,
This was never reflected in existing stapler designs.

In view of the above problems, it is an object of the present invention to realize a stapler that is more convenient for all users with a simple structure.

[0006]

That is, a stapler according to the present invention comprises a pair of levers, and a stapling mechanism for striking a needle for binding a sheet is interposed between the pair of levers, and the stapler is arranged in a substantially horizontal plane. A first grounding portion is provided on the distal end portion of the lever so as to be in contact with and to allow the tip end side to stand upright, and a second grounding portion for contacting with a substantially horizontal plane to allow the base end side to stand upright The grounding portion is provided at the base end portion of the lever.

With such a structure, it is possible to stand upright on a required substantially horizontal surface such as on the top plate of a desk. Therefore, the stapler does not unnecessarily occupy the top of the desk or the like, and the space can be effectively used. Moreover, when the stapler is erected, the base end side may be down or the leading end side may be down. Therefore, the user who presses the lever while grasping the thumb as if to attach it to the tip side is made to stand up at the base end side, and the user who grasps the little finger as being attached to the tip side as to press the lever is made to stand up at the tip side. You can As a result, the stapler has a simple structure and is convenient for all users.

A grounding surface is provided at the tip of each of the pair of levers, and the grounding surfaces are set so as to be substantially flush with each other to form the first grounding portion. The stability of the stapler in the upright state can be enhanced by providing the grounding surfaces at the ends and setting the grounding surfaces so that they are substantially flush with each other to form the second grounding portion.

A pair of levers rotate about the same axis, and the first grounding portion relatively rotates a predetermined angle so as to bring one lever closer to the other lever from its initial position. It is possible to make the tip end stand up while being in contact with a substantially horizontal surface in a fixed state at the folded position, or the second grounding portion may move one lever from the initial position to the other. If it is possible to raise the base end side downward by contacting with a substantially horizontal surface in a state where the stapler is fixed at the folded position relatively rotated by a predetermined angle so as to approach the lever of It can be stored in a smaller folded state. This effectively functions when the stapler is displayed or stored.

Further, the stapler is often provided with a needle removing claw for pulling out a staple for binding sheets, and the needle removing claw is connected to the first grounding portion and the second grounding portion. If it is provided between them, the needle-removing claw will not interfere when the stapler is placed upright. Further, one of the pair of levers is provided with a needle-removing claw at its base end side for pulling out a needle that binds a sheet, and the needle-removing claw is provided at the protruding end thereof. The second part
It is also conceivable for the embodiment to be arranged so that the grounding part of the above can be configured.

At least one of the pair of levers has an exposed portion formed by two-color molding in which a hard resin and a soft resin are separately exposed to expose, and the soft resin is the first portion of the lever. If exposed to a part or all of the ground contact portion, the friction at the first ground contact portion is increased, which contributes to the stability of the stapler in the upright state. Alternatively, if the soft resin is exposed on a part or all of the second ground contact portion of the lever, the friction at the second ground contact portion is increased, and the stability of the stapler in the standing state is also increased. Contribute to.

In order to allow the stapler to be folded in a small size, an engaging portion is provided which can selectively engage one lever and the other lever to fix the relative positions of both levers. , By engaging or disengaging the engaging portion, one lever and the other lever are relatively rotated by a predetermined angle so that one lever approaches the other lever from its initial position. It is desirable that the position and the open position in which each lever is rotated so as to be separated from its initial value can be selectively taken. As a specific embodiment thereof, the engaging portion is On one of the levers, on the other lever that engages with this engaging groove, and on the other lever that movably operates this engaging protrusion. It is preferable to provide the operation part provided.

Further, as a concrete embodiment of each of these parts, an opening is formed in the engaging groove in a direction in which the other lever can be opened, and each lever is communicated with this opening to fold the lever. A retracted position for retracting the engaging protrusion so that the engaging protrusion can be moved closer to the position, and a fixed position for fixing the engaging protrusion by positioning each lever in the folding position, the engaging protrusion is provided with the operation position. By providing an engagement shaft that can move in the engagement groove in conjunction with the operation of the portion and operating the operation portion, the engagement shaft can be positioned at each position of the opening, the retracted position, and the fixed position. It is mentioned that it is configured.

BEST MODE FOR CARRYING OUT THE INVENTION <First Embodiment> An embodiment of the present invention will be described below with reference to FIGS. As shown in FIGS. 1 and 2, the stapler S according to the present embodiment.
Includes a pair of levers, an upper lever 1 and a lower lever 2, and a stapling mechanism 3 for striking a needle for binding a sheet is interposed between the upper lever 1 and the lower lever 2. The basic configuration of the stapler S is similar to that of the existing one. That is, the upper lever 1 is provided with the stapling mechanism 3 and the lower lever 2 is provided with the needle receiving portion 4 for receiving the needles ejected from the stapling mechanism 3, so that the function as a paper binding device is exhibited. It is a thing.

The upper lever 1 has a partial arc shape which bulges upward in a side view. On the other hand, the lower lever 2 has a substantially flat plate shape. The upper lever 1 and the lower lever 2 are, for example, covered with resin covers to embody their external shapes. Incidentally, in the illustrated example, the cover forming the outer shape of the upper lever 1 and the cover forming the outer shape of the lower lever 2 are manufactured as a synthetic resin two-color molded product, and the portion G corresponding to the grip with which the user's finger abuts is hard. A resin (soft resin) that is softer than the other parts made of resin as the main equipment is used as the equipment.

The upper lever 1 and the lower lever 2 are
It rotates about the same shaft 6. In this embodiment, the shaft 6 around which the upper lever 1 and the lower lever 2 rotate is set to the base end side. More specifically, a shaft 6 is provided inside the base end portion of the upper lever 1 so as to extend along the width direction, and a bearing is provided on the lower lever 2 so that the levers 1 and 2 rotate by engaging them. Has been realized.

In the stapler S having such a structure, in this embodiment, the first grounding portion 8 which is in contact with the substantially horizontal surface H and allows the leading end side to be erected downward is provided at the leading end portion of the lever, In addition, a second grounding portion 9 that is in contact with the substantially horizontal surface H and allows the base end side to stand upright is provided at the base end portion of the lever.

More specifically, the upper lever 1 and the lower lever 2
Grounding surfaces 11 and 21 are provided at the tip ends of the. The ground planes 11 and 21 are set to be substantially flush with each other. As a result, as shown in FIG. 3, the stapler S can be erected on the substantially horizontal surface H by bringing the ground contact surfaces 11 and 21 into contact with the substantially horizontal surface H with the leading end side facing downward. That is, these ground planes 11 and 21 serve as the first ground section 8.

Similarly, the upper lever 1 and the lower lever 2
Ground planes 12 and 22 are also provided at the base end portions of the above. The ground planes 12 and 22 are set to be substantially flush with each other. As a result, as shown in FIG. 4, the ground planes 12 and 22 can be brought into contact with the substantially horizontal surface H with the base end side facing downward, and the stapler S can be erected on the substantially horizontal surface H. That is, these ground planes 12 and 22 serve as the second ground section 9.

As a result, in the case of a user who holds the little finger as shown in FIG. 5 so as to attach it to the tip side and pushes the lever, when the stapler S is not used, as shown in FIG. Can stand upright. When the stapler S is to be used again, it can be used immediately if the stapler S which is standing upright with the front end side down is grasped and lifted in that direction. Alternatively, as shown in FIG. 6, in the case of a user who holds the thumb so that his / her thumb is attached to the tip side and pushes the lever, when the stapler S is not used, the user stands up on a substantially horizontal plane H with the base side down as shown in FIG. Can be placed. When the stapler S is to be used again, it can be used immediately by grasping and lifting the stapler S which has been erected with the base end side down in the same direction.

Further, a device G having a high friction coefficient, such as rubber, is used for the portion G corresponding to the grips of the upper lever 1 and the lower lever 2 of the stapler S in the illustrated example, which are brought into contact with the user's fingers. The rubber or the like forming the part G extends to the end surfaces of the upper lever 1 and the lower lever 2. That is, the soft resin is exposed on a part of the ground planes 11 and 21 forming the first ground section 8. As a result, since the friction at the exposed portion of the soft resin becomes large, the stapler S is stable and hardly slips on the substantially horizontal surface H in the standing state shown in FIG. In addition, as a configuration different from the illustrated example, a soft resin lever 1,
It may be extended to the base end portion of 2 and exposed to a part or all of the second ground contact portion 9. Alternatively, only one of the upper lever 1 and the lower lever 2 may be provided with a portion using the soft resin as a material.

Further, the stapler S according to the present embodiment.
Can be erected on a substantially horizontal plane H in a state where the lower lever 2 is fixed at a folding position C in which the lower lever 2 is relatively rotated from an initial position F by a predetermined angle so as to approach the upper lever 1. There is.

Normally, the stapler S is provided with an urging means such as a spring for urging the levers away from each other. Therefore, when no external force is applied to the upper lever 1 and the lower lever 2, the lower lever 2 is at the initial position F separated from the upper lever 1 by a predetermined angle.
This state is shown in FIGS. 1, 3 and 4. Then, by applying an external force to the upper lever 1 and the lower lever 2, the lower lever 2 is relatively rotated with respect to the upper lever 1, and the upper lever 1 and the lower lever 2 can be brought close to each other. Of course, the upper lever 1 and the lower lever 2 are sufficiently close to each other so that the lower lever 2
When the needle pushes the needle striking mechanism 3, the needle is driven by the needle striking mechanism 3 by its reaction.

Thus, the stapler S according to this embodiment
Has a stopper lock mechanism that stops the relative rotation of the lower lever 2 with respect to the upper lever 1 at a position immediately before the lower lever 2 comes into contact with the stapling mechanism 3. That is, the lower lever 2 is relatively rotated by a predetermined angle so as to be closer to the upper lever 1 than the initial position F, and the lower lever 2 is arranged at the folding position C immediately before contacting the stapling mechanism 3. The lock can be applied later by operating the operation unit 5 of the stopper lock mechanism.

FIG. 7 and FIG. 8 show a state in which the upper lever 1 and the lower lever 2 are locked at the folding position C so as to prevent them from rotating. Then, even in this state, as shown in FIG. 7, the first grounding portion 8, in other words, the grounding surfaces 11, 21 are in contact with the substantially horizontal surface H, and the stapler S is erected with the leading end side downward. It is possible. More specifically, the ground contact surfaces 11 and 21 on the front end side are formed so as to be almost exactly flush with each other when the upper lever 1 and the lower lever 2 are fixed at the folding position C. Therefore, when the lower lever 2 is not in the collapsed position C (particularly when the lower lever 2 is in the initial position F), the contact surfaces 11 and 21 on the tip end side are slightly lost in levelness. The function as the first grounding portion 8 is not impaired. Similarly, even in a state in which the upper lever 1 and the lower lever 2 are locked so as to prevent the upper lever 1 and the lower lever 2 from rotating at the folded position C, as shown in FIG. 8, the second grounding portion 9, in other words, For example, the ground contact surfaces 12 and 22 are in contact with the substantially horizontal surface H, and the stapler S can be erected with the base end side downward. Further, the ground contact surfaces 12 and 22 on the base end side are formed so as to be substantially flush with each other when the upper lever 1 and the lower lever 2 are fixed at the folding position C. Therefore, when the lower lever 2 is not in the folded position C (particularly, when the lower lever 2 is in the initial position F), the ground planes 12 and 22 on the base end side are slightly lost in the flatness. This does not impair the function of the second ground portion 9.

In addition, as shown in FIG. 2, a needle-removing claw 7 for pulling out the needle that binds the sheets is provided between the first grounding portion 8 and the second grounding portion 9. It is provided. Specifically, the needle removing claw 7 is provided at the base end portion of the lower lever 2. The tip of the needle-removing claw 7 has the tip of the ground-contacting surface 2 so that the needle-removing claw 7 does not intersect with the plane extending from the ground-contacting surface 22.
It is configured to project to a position closer to the tip side than 2.

Therefore, according to this embodiment, the stapler S is used by providing the first grounding portion 8 at the tip of the lever and the second grounding portion 9 at the base of the lever. When not in use, it can be erected on a required substantially horizontal surface H such as on the top of a desk. Therefore, the stapler S does not unnecessarily occupy the top of the desk or the like, and the space can be effectively used.

Furthermore, when trying to use the placed stapler S, it is necessary to temporarily lift it up. However, when an elongated object is laid down, the portion that can be held by the human hand is present only in a narrow vertical range. Therefore, the user feels stress when grasping and lifting this. However, if the stapler S is placed upright, the portion that can be held by the human hand will exist over a wide range in the vertical direction. Therefore, when it is going to be used, it can be easily grasped and lifted. By these actions,
The stapler S becomes extremely convenient for the user.

Moreover, when the stapler S is erected, the base end side may be down or the front end side may be down.
Therefore, the user who presses the lever while grasping the thumb as if to attach it to the tip side is made to stand up at the base end side, and the user who grasps the little finger as being attached to the tip side as to press the lever is made to stand up at the tip side. You can As a result, the stapler S has a simple structure and is convenient for all users.

Grounding surfaces 11, 21 are provided at the tips of the upper lever 1 and the lower lever 2, respectively.
Are set to be substantially flush with each other to form the first grounding portion 8, or grounding surfaces 12 and 22 are provided at the base end portions of the upper lever 1 and the lower lever 2, respectively.
The second and second parts are set so that they are substantially flush with each other.
By using the grounding portion 9 as described above, the stability of the stapler S in the upright state can be enhanced.

The first ground contact portion 8 is fixed in a folded position C in which the lower lever 2 is relatively rotated by a predetermined angle so as to bring the lower lever 2 closer to the upper lever 1 from its initial position F, and the substantially horizontal surface H. It is possible to raise the tip end side downward by contacting with, or the second ground contact portion 9 has a predetermined angle relative position so that the lower lever 2 is closer to the upper lever 1 than its initial position F. If it is possible to raise the base end side downward by contacting the substantially horizontal surface H while being fixed at the folding position C that has been mechanically rotated, place the stapler S in a state of being folded smaller. Can be kept. Therefore,
When the stapler S is displayed or stored, it can effectively function to save space.
In addition, since the stapler S according to the present embodiment is provided with the stopper lock mechanism, the use of the stopper lock mechanism can bring about an effect that it is not bulky at the time of packing or transportation.

The stapler S is provided with a needle removing claw 7 between the first grounding portion 8 and the second grounding portion 9. Therefore, when the stapler S is placed upright, the needle removing claw 7 does not interfere.

Each of the upper lever 1 and the lower lever 2 has an exposed portion formed by two-color molding in which a hard resin and a soft resin are separated and exposed (in a mode in which the soft resin is used for the portion G). By exposing the soft resin to the first grounding portions 8 of the upper lever 1 and the lower lever 2, the friction at the first grounding portions is increased, and the stapler is stable in the upright state. It has become an enhanced one.

The present invention is not limited to the embodiment described in detail above. In particular, the first grounding portion 8 and the second grounding portion 9 are not limited to being composed of the grounding surfaces 11, 21, 12, 22. Further, the position where the shaft 6 that allows the upper lever 1 and the lower lever 2 to rotate is not limited to the above-described aspect. Further, it does not prevent the needle removing claw 7 from being provided at a position other than the base end portions of the upper lever 1 and the lower lever 2.

<Second Embodiment> Another embodiment of the present invention will be described below with reference to FIGS. 9 to 16. As shown in FIGS. 9 and 10, the stapler S according to the present embodiment
Includes a pair of levers, an upper lever 1 and a lower lever 2, and a stapling mechanism 3 for striking a needle for binding a sheet is interposed between the upper lever 1 and the lower lever 2.

On the other hand, the lower lever 2 integrally includes a lower lever base body 2a having a substantially flat plate shape and a lower lever main body 2b formed by bending a metal plate arranged on the upper surface side of the lower lever base body 2a. More specifically, the lower lever main body 2b has a substantially U-shaped cross section including a base body bottom plate 2b1 placed on the lower lever base body 2a and standing walls 2b2 in which both end edges of the base body bottom plate 2b1 are erected. It is a thing. Further, each standing wall 2b2 is formed such that the height dimension thereof is higher toward the base end side and gradually lowers toward the front end side, and at the base end side thereof, a bearing hole 2bx for supporting a shaft 6 described later is formed. A pair of reinforcing ribs 2by are provided, and further, one standing wall 2b2 is provided with an engagement groove M described later. The upper lever 1 and the lower lever base body 2a are covered with, for example, a resin cover to embody their external shape. Incidentally, in the illustrated example, the cover forming the outer shape of the upper lever 1 and the lower lever base 2
The cover forming the outer shape of a is manufactured as a synthetic resin two-color molded product, and the portion G corresponding to the grip with which the user's finger abuts has a softer resin (softer than other portions mainly made of hard resin). Resin) is used as equipment.

The upper lever 1 and the lower lever 2 are
It rotates about the same shaft 6. In this embodiment, the shaft 6 around which the upper lever 1 and the lower lever 2 rotate is set to the base end side. More specifically, the shaft 6 is provided inside the base end portion of the upper lever 1 so as to extend along the width direction, and the lower lever body 2b is provided with a bearing. Has been realized. Further, a needle removing claw 7 is provided at the base end portion of the lower lever main body 2b for pulling out the needle that binds the sheets. The needle removing claw 7 is formed by projecting the base end surface of the lower lever base body 2a as a base end and projecting in a substantially triangular shape in a plan view so that the width becomes gradually smaller toward the tip thereof. It is integrally formed by bending 2b.

In the stapler S having such a structure, in the present embodiment, the first grounding portion 8 which is in contact with the substantially horizontal plane H and allows the leading end side to stand upright is provided at the leading end portion of the lever, In addition, a second grounding portion 9 that is in contact with the substantially horizontal surface H and allows the base end side to stand upright is provided at the base end portion of the lever.

More specifically, the upper lever 1 and the lower lever 2
Grounding surfaces 11 and 21 are provided at the tip ends of the. The ground planes 11 and 21 are set to be substantially flush with each other. As a result, as shown in FIG. 11, the stapler S can be erected on the substantially horizontal surface H by bringing the ground contact surfaces 11, 21 into contact with the substantially horizontal surface H with the leading end side facing downward. That is, these ground planes 11 and 21 serve as the first ground section 8.

Similarly, the grounding surface 12 is provided on the upper lever 1, and the protruding end portion 71 is provided at the tip of the needle removing claw 7 provided on the lower lever 2.
Is provided. Then, the grounding surface 12 and the protruding end portion 7
1 and 1 are set to be substantially flush with each other. As a result, as shown in FIG. 12, the ground surface 12 and the projecting end portion 71 are brought into contact with the substantially horizontal surface H with the base end side facing downward, and the stapler S can be erected on the substantially horizontal surface H. That is, the grounding surface 12 and the projecting end portion 71 serve as the second grounding portion 9.

As a result, in the same manner as that shown in FIG. 5 in the first embodiment, in the case of a user who presses the lever while grasping the little finger to attach it to the tip side, when the stapler S is not used, as shown in FIG. Side down and approximately horizontal plane H
Can stand upright. When the stapler S is to be used again, it can be used immediately if the stapler S which is standing upright with the front end side down is grasped and lifted in that direction.
Alternatively, as in the case of the first embodiment shown in FIG. 6, in the case of a user who pushes the lever by grasping the thumb so that the thumb is attached to the tip side, when the stapler S is not used, FIG.
As shown in, it can be erected on a substantially horizontal surface H with the base end side down. When the stapler S is to be used again, it can be used immediately by grasping and lifting the stapler S which has been erected with the base end side down in the same direction.

Further, for the portion G corresponding to the grip with which the user's finger is set, which is set on the upper lever 1 and the lower lever 2 of the stapler S in the illustrated example, equipment having a high friction coefficient such as rubber is used. The rubber or the like forming the part G extends to the end surfaces of the upper lever 1 and the lower lever 2. That is, the soft resin is exposed on a part of the ground planes 11 and 21 forming the first ground section 8. As a result, since the friction at the exposed portion of the soft resin becomes large, the stapler S in the standing state shown in FIG. In addition, as a configuration different from the illustrated example, a soft resin lever 1,
It may be extended to the base end portion of 2 and exposed to a part or all of the second ground contact portion 9. Alternatively, only one of the upper lever 1 and the lower lever 2 may be provided with a portion using the soft resin as a material.

Further, the stapler S according to the present embodiment
Can be erected on a substantially horizontal plane H in a state where the lower lever 2 is fixed at a folding position C in which the lower lever 2 is relatively rotated from an initial position F by a predetermined angle so as to approach the upper lever 1. There is.

Normally, the stapler S is provided with an urging means such as a spring for urging the levers in a direction in which the levers are moved away from each other. Therefore, when no external force is applied to the upper lever 1 and the lower lever 2, the lower lever 2 is at the initial position F separated from the upper lever 1 by a predetermined angle.
This state is shown in FIGS. 9, 11 and 12.
Then, by applying an external force to the upper lever 1 and the lower lever 2, the lower lever 2 is relatively rotated with respect to the upper lever 1, and the upper lever 1 and the lower lever 2 can be brought close to each other. Of course, when the upper lever 1 and the lower lever 2 are sufficiently close to each other and the lower lever 2 pushes the stapling mechanism 3, the needle is driven by the stapling mechanism 3 by the reaction thereof.

Thus, the stapler S according to this embodiment
Is provided with a stopper lock mechanism SL that is an engaging portion that stops the relative rotation of the lower lever 2 with respect to the upper lever 1 at a position immediately before the lower lever 2 contacts the stapling mechanism 3.
That is, the lower lever 2 is relatively rotated by a predetermined angle so as to be closer to the upper lever 1 than the initial position F, and the lower lever 2 is arranged at the folding position C immediately before contacting the stapling mechanism 3. The lock can be applied later by operating the operation unit 5 of the stopper lock mechanism SL. Further, the stopper lock mechanism SL is released, and the upper lever 1 and the lower lever 2 are rotated so as to be separated from the initial position F, so that each lever can be positioned at the open position K shown in FIG.

More specifically, this stopper lock mechanism S
Describing L, the stopper lock mechanism SL includes an engagement groove M provided in one standing wall 2b2 on the base end side of the lower lever body 2b, and a cylindrical engagement shaft capable of engaging with the engagement groove M. 5
1 and an elongated hole-shaped through hole 1a communicating with the engagement shaft 51.
1 and an operation guide portion 1a provided with a counterbore portion 1a2 on the outer side of the through hole 1a1 on the side wall 10 of the upper lever 1, and an operation so that the engagement shaft 51 can move in the operation guide portion 1a. And an operating section 5 for operating. Note that FIG.
As shown in FIG. 1 and the like, the engagement shaft 51 has a pull-out preventing portion 5 having a substantially circular shape in a plan view at the end opposite to the end provided with the operating portion 5.
2 is provided to prevent the operation guide 1a from falling off.
The engagement shaft 51 and the removal preventing portion 52 form the engagement protrusion 50. Further, the engagement groove M is shown in FIG.
As shown in FIG. 16, an opening M1 that opens in a direction in which the upper lever can be opened, and a retracted position that communicates with the opening M1 and retracts the engagement shaft 51 so that each lever can be closer to the folded position C. It is set so as to have M2 and a fixed position M3 at which each lever can be positioned at the folded position to fix the engagement shaft 51.

The stopper lock mechanism S having such a structure
At L, when the upper lever 1 and the lower lever 2 are brought close to each other and positioned at the folded position C, a force for returning to the initial state F is exerted on the upper lever 1 by the biasing means. Therefore, when the operation shaft 5 is operated to position the engagement shaft 51 at the fixed position M3, the downward surface M31 of the engagement groove M at the fixed position M3 comes into contact with the engagement shaft 51, and the contacted state, that is, the folded position. At C, each lever is fixed. In this way, the upper lever 1,
The locked state for fixing the rotation of the lower lever 2, that is, the engaged state can be obtained. On the other hand, when the operation portion 5 is operated to position the engagement shaft 51 at the retracted position M2 and the upper lever 1 is further opened, the engagement shaft 51 can be disengaged from the opening M1 of the engagement groove M, that is, the engagement. It can be released and each lever can be positioned in the open position K as shown in FIG. That is, by engaging or disengaging the stopper lock mechanism SL, each lever can selectively take the folded position C and the open position K.

FIG. 13 and FIG. 14 show a state in which the upper lever 1 and the lower lever 2 are locked at the folding position C so as to fix the rotation thereof. Then, even in this state, as shown in FIG. 13, the first grounding portion 8, in other words, the grounding surfaces 11, 21 are in contact with the substantially horizontal surface H and the stapler S is erected with the leading end side downward. It is possible.
More specifically, the ground contact surfaces 11 and 21 on the tip side.
Is formed so that the upper lever 1 and the lower lever 2 are almost exactly flush with each other in a state where the upper lever 1 and the lower lever 2 are fixed at the folded position C. Therefore, when the lower lever 2 is not in the collapsed position C (particularly when the lower lever 2 is in the initial position F), the contact surfaces 11 and 21 on the tip end side are slightly lost in levelness. The function as the first grounding portion 8 is not impaired. Similarly, even when the upper lever 1 and the lower lever 2 are locked to fix the rotation of the upper lever 1 and the lower lever 2 at the folded position C, as shown in FIG. 14, the second ground portion 9, in other words, For example, the grounding surface 12 and the projecting end portion 71 are in contact with the substantially horizontal surface H, and the stapler S can be erected with the base end side downward. Further, the grounding surface 12 on the base end side and the projecting end portion 71 are formed so as to be substantially exactly flush with each other when the upper lever 1 and the lower lever 2 are fixed at the folding position C. Therefore, when the lower lever 2 is not in the collapsed position C (particularly when the lower lever 2 is in the initial position F), the flushness between the grounding surface 12 on the base end side and the projecting end 71 is slightly lost. However, this does not impair the function of the second ground portion 9.

Therefore, according to this embodiment, the stapler S is used by providing the first grounding portion 8 at the tip of the lever and the second grounding portion 9 at the base of the lever. When not in use, it can be erected on a required substantially horizontal surface H such as on the top of a desk. Therefore, the stapler S does not unnecessarily occupy the top of the desk or the like, and the space can be effectively used.

Furthermore, when trying to use the placed stapler S, it is necessary to temporarily lift it up. However, when an elongated object is laid down, the portion that can be held by the human hand is present only in a narrow vertical range. Therefore, the user feels stress when grasping and lifting this. However, if the stapler S is placed upright, the portion that can be held by the human hand will exist over a wide range in the vertical direction. Therefore, when it is going to be used, it can be easily grasped and lifted. By these actions,
The stapler S becomes extremely convenient for the user.

Moreover, when the stapler S is erected, the base end side may be down or the front end side may be down.
Therefore, the user who presses the lever while grasping the thumb as if to attach it to the tip side is made to stand up at the base end side, and the user who grasps the little finger as being attached to the tip side as to press the lever is made to stand up at the tip side. You can As a result, the stapler S has a simple structure and is convenient for all users.

Grounding surfaces 11 and 21 are provided at the tips of the upper lever 1 and the lower lever 2, respectively.
Are set to be substantially flush with each other to form the first grounding portion 8, or the grounding surface 12 and the projecting end portion 71 are provided at the base end portions of each of the upper lever 1 and the lower lever 2. The stability of the stapler S in the upright state can be improved by setting the grounding surface 12 and the projecting end portion 71 so as to be substantially flush with each other to form the second grounding portion 9.

The first ground contact portion 8 is fixed in the folded position C in which the lower lever 2 is relatively rotated by a predetermined angle so as to bring the lower lever 2 closer to the upper lever 1 from its initial position F, and the substantially horizontal surface H. It is possible to raise the tip end side downward by contacting with, or the second ground contact portion 9 has a predetermined angle relative position so that the lower lever 2 is closer to the upper lever 1 than its initial position F. If it is possible to raise the base end side downward by contacting the substantially horizontal surface H while being fixed at the folding position C that has been mechanically rotated, place the stapler S in a state of being folded smaller. Can be kept. Therefore,
When the stapler S is displayed or stored, it can effectively function to save space.
In addition, since the stapler S according to the present embodiment is provided with the stopper lock mechanism SL, the use of the stopper lock mechanism SL can bring about an effect that it is not bulky at the time of packing or transporting.

The upper lever 1 and the lower lever 2 have an exposed portion formed by two-color molding in which a hard resin and a soft resin are separated and exposed (in the mode in which the soft resin is used for the portion G). By exposing the soft resin to the first grounding portions 8 of the upper lever 1 and the lower lever 2, the friction at the first grounding portions is increased, and the stapler is stable in the upright state. It has become an enhanced one.

The present invention is not limited to the embodiment described in detail above. In particular, the first grounding portion 8 and the second grounding portion 9 are not limited to being configured by the grounding surfaces 11, 21, 12 and the protruding end portion 71. Further, the position where the shaft 6 that allows the upper lever 1 and the lower lever 2 to rotate is not limited to the above-described aspect. In addition, remove the needle remover claw 7
It does not prevent the lower lever 2 from being provided at a location other than the base end portion thereof.

Further, the groove M of the stopper lock mechanism SL
The shape and configuration of the above, and the shapes and configurations of the engaging protrusion 50 and the operating portion 5 are not limited to those of the present embodiment, and an embodiment in which the stopper lock mechanism SL is applied to the first embodiment is also available. Conceivable.

The specific construction of each of the other parts is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
