Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a stapler, and more specifically, it is capable of flattening the tip of the staple that is stapled to the back side of the paper or other materials when stapled together. Regarding staplers.

[Conventional technology]

In conventional staplers, an anvil has an integrally formed internal concave surface having a pair of curved surfaces, and the tips of the staples are bent by the pair of curved surfaces to bind papers and the like. In this case, the distance between the tip of the driver and the anvil is
It was determined by the thickness of the paper or other material inserted between the driver and the anvil.

[Problem that the invention seeks to solve]

According to the stapler having such a conventional structure, the leading end of the staple is bent by the two inner faces of the anvil to form a semicircular shape. Furthermore, the stroke of the driver relative to the anvil is fixed. For this reason, even if the bottom surface of the central part of the anvil is flat, the leading end of the staple, which has been once shaped into a circular shape, will be stapled in this shape. This is shown in Figure 18A and ! @1
．． This will be briefly explained using Figure 8B. 7 Figure 18A and 1.8
In Figure B, reference numeral 1 (l O) indicates the base of the stapler, and an anvil 101 is formed on this base 100.

When the paper 102 placed between the base 100 and the anvil (not shown) is stapled, the tip WB of the staple 104 is first shaped into an arc by the curved surface of the anvil by the driver 103. When the driver 103 is further moved downward, the tip of the staple 104 becomes semicircular. 1. For this reason, there is a semicircular protrusion on the back side of the bound paper 102, which is disadvantageous in that it looks bad and may get caught on other objects.

[Means for solving problems]

The present invention eliminates the drawbacks of the conventional stapler described above, and provides a stapler that binds papers, etc. by pressing staples between a driver and an anvil, in which an internal concave surface of the anvil forms a pair of inclined surface portions and a pair of inclined surface portions. and a separate pressing surface, and the inclined surface part of said "-" and the pressing surface are relatively movable, and the tip of the staple is formed by said "-".
After bending at the pair of inclined surfaces, the relative positions of the driver and the pressing surface are further brought closer to flatten the leading end of the staple.

The relative positions of the driver and the pressing surface may be brought close to each other by relative movement of the pair of sloped surface parts and the pressing surface mainly along the horizontal direction, or by moving the pair of sloped surface parts and the pressing surface mainly in the horizontal direction. This may be performed by relative movement substantially along the direction of movement of the driver.

The length of the pressing surface may be longer or shorter than the length between the inclined surface portions in the longitudinal direction of the internal concave surface of the anvil. In addition, it is possible to divide the pressing surface into two or more parts, or to divide the pressing surface into two or more parts, or to
A diagonal separating guideway may be provided on the pressing surface.

Furthermore, the pair of inclined surface portions may be inclined in opposite directions with respect to the lateral (perpendicular) direction of the longitudinal direction of the internal concave surface of the anvil.

[Effect]

In the above configuration, the pair of inclined surface portions and the pressing surface are formed separately, and are relatively movable.

Therefore, after the tip of the staple is bent at the inclined surface portion, the relative positions of the driver and the pressing surface can be brought closer to each other. Therefore, once bent staples can be flattened between the pressing surface and the driver.

〔Example〕

In explaining the present invention based on examples below, examples of relative movement between a pair of inclined surface parts and a pressing surface for bringing the relative positions of the driver and the pressing surface closer together are classified as follows.

(First example)...In the case of classification (Δ-1-1), 1st A
1C and 2 are schematic diagrams showing the main structure of the first embodiment. In the figure, a curved table 2 is inserted through a base 1 of the stapler so as to be movable back and forth in the longitudinal direction of the stapler body (base 1). Reference numeral 3 is a gun gun, and reference numeral 4 is a driver. The curved table 2 has a pair of inclined surfaces 5.
, 5 (curved surfaces in this embodiment) are formed on the base 1, and a pressing surface 6 is formed on the base 1. As seen in FIG. 2, the pressing surface 6 is formed longer than the distance between the pair of inclined surface portions 5, but the pressing surface 6 is not limited to this and may be formed shorter. - The pair of inclined surface portions 5 and pressing surface 6 constitute an anvil.

The operation of this embodiment will be explained with reference to FIGS. 3A to 3D. In FIG. 3A, sheets 8 to be bound are inserted between the magazine 3 and the curved table 2. At this time, since the curved surface table 2 is located in front of the base 1, the inclined surface part 5 and the pressing surface 6 are both on the same straight line -I. Then, in FIG. 3B, when the driver 4 is pushed down as in the conventional method by operating a handle (not shown), the staple 7 is first bent by the inclined surface portion 5. Thereafter, as shown in FIG. 3C, while pressing the staple 7 with the driver 4, the curved table 2 is moved backward using a finger. By further pressing down the driver 4, the tip of the staple 7 is flattened by the pressing surface 6 of the base 1. In this way, after the staple 7 is bent by the inclined surface portion 5, the driver 4 can be further pressed down toward the pressing surface 6.

In the first embodiment, the curved surface table 2 is moved rearward and the inclined surface portion 5 is
and the pressing surface 6 are moved relative to each other.

However, on the contrary, by providing the slope section 5 at the rear of the curved surface table 2 and the pressing surface 6 at the corresponding position on the base 1, the curved surface table 2 can be moved forward and the slope section 5 and the pressing surface 6 can be moved forward.
Of course, it is also possible to perform relative movement with. Moreover, various modifications are possible for the relative movement of the stapler in the longitudinal direction, which is the category (8). For example, each of the pair of sloped surface parts can be moved to one side of the base 8, the sloped surface part of the month that is rotatably attached to the base can be rotated, or each of the pair of sloped surface parts can be moved oppositely to the pressing surface. A relative movement in the direction is also possible.

In this embodiment, the inclined surface portion 5 is moved manually, but it is also possible to move this automatically.

The configuration for this purpose is: (1) a weak elastic body that always acts as a force to keep the inclined surface portion and/or the pressing surface in place at or before the start of use; (b) a weak elastic body that acts at all times before starting use (2) A member that acts in the reverse stroke during use, or a member that combines (a) and (b); ) a member that engages between the handle and the base; (b) a member that engages between the driver, anvil, and the base; and (3) opening from the start of use to the final stroke of use;
(a) A member that engages or disengages depending on the relative position of the handle and the magazine, or (b) The handle and the base, as a function of fixing the inclined surface portion and/or the pressing surface in a fixed position and releasing it in the final process of use. A member is required that engages or disengages depending on its relative position.

(Second Example)...In the case of classification (8-1-3) No. 4A is a schematic diagram showing the main structure of the stapler of the second example.
This embodiment will be explained with reference to FIGS. 4B and 5. In the figure, parts corresponding to those in the first embodiment are given the same reference numerals, and as is clear from the 1-degree view, the detailed explanation of which is omitted, in this embodiment, the inclined surface portion 5 moves obliquely downward. As explained in the first embodiment, it is also possible to move this inclined surface section 5 automatically.

(Third Embodiment) In the case of classification (A-2-4), the third embodiment is a stapler in which the pressing surface moves and rises. FIG. 6 and FIG. fpj7 are schematic diagrams showing the main parts thereof. In the third embodiment, base 1
An inclined surface portion 5 is formed integrally with the base 1, and a flat table 9 inserted through the base 1 is further provided. An inclined stepped portion 10 is formed at the tip of the base 1 and the lower inner surface of the flat table 9 as shown in the figure. Therefore, moving the flat table 9 backward =
11- As a result, the plane table 9 is raised twice, so that the pressing surface 6 of
will rise.

Further, as described in the first embodiment, the pressing surface can be automatically moved in this embodiment as well.

Incidentally, a modification of the classification (Δ-2-4) shown in FIG. 8 is also possible. In the embodiment of FIG. 8, the plane table 5] is movable but does not directly form a pressing surface, but has a pressing surface 6 rotatably provided on a separate base.

(Fourth example)...9th case of classification (B=1.=2)
The figure is a schematic view of the main part of the fourth embodiment, and is an example in which the inclined surface part is not moved in the direction of the stapler user, but is lowered along the moving direction of the stapler driver.

For this reason, in this embodiment, the base is composed of a bottom base 1A and an upper base 1B whose rear part is pivotally supported by the bottom base 1A and whose front part is movable up and down.

17. An inclined surface portion is formed integrally with the upper surface base 1B, and a fixed pressing surface is formed on the bottom surface base 1A. Further, a retaining member 11 is provided as a structure for automatically operating the stapler of the present invention as described in the second embodiment. This retaining member 11 satisfies the requirements for automatic operation. A cradle 12 for the front base 1B is formed at the leading end of the retaining member 11, and a lever fitting part 13 is formed at the rear end. Furthermore, a lever 15 that fits into the lever fitting portion 13 is fixed to the handle 14. In this embodiment, when the handle 14 is pressed and the handle 14 is initially pressed, the two-sided base 1B is supported by the pedestal 12, and during this time the staple tip is bent by the inclined surface portion. However, when the handle 14 is lowered, the retaining member 11 is pulled rearward via the lever 15, and the pedestal 12 falls below the bottom base IA. At this time"
The two-sided base 1B can be further rotated and lowered, and as a result, the relative positions of the pressing surface and the driver 4 can be brought closer to each other.

-1- Note: The member 11 can be modified in various ways as described in the first embodiment.

Further, as a modification example for implementing this automation, the first example shown in FIGS. 10 and 11 can be considered. In this modification, the inclined surface portion and the pressing surface do not move in the direction of the stapler user. A sliding slide 16 is inserted through the tip of the base 1 and moved. and base 1
A pressing surface 6 is formed on two sides of the distal end of the base 1, and a rotating plate 17 is provided which is pivotally supported on the base 1. The rotating plate 17 has an inclined surface portion 5 formed therein. Further, an inclined step portion 10 is formed on each of the rotating plate 1'7 and the slide 16.

In conjunction with the rotation of the rotation plate 17, the rotation plate 1 is rotated at the beginning of use.
The bottom surface of slide 1G engages with the bottom surface of slide 1G, and then the rotating plate 1
7 and both inclined steps 10, 10 of the slide 16 engage with each other, so that the slide 16 is moved forward after the final stroke of use. In this way, it is possible to bring the pressing surface 6 and the driver closer to each other in the final stroke of use and to automate the relative positions.

(Fifth Example) In the case of classification (B-2-]), the fifth example moves the pressing surface toward the stapler user! FJJ This is an example of dividing the distance along the moving direction of the driver without changing the distance. FIG. 12 shows an original diagram of its operation. code 1
Reference numeral 8 denotes an engaging member, which is supported by a fulcrum 19 on the bottom surface of the base I, and has an engaging portion 2 that engages with the handle 14 at one end.
0 is formed, and a pressing surface 6 is formed at the other end. The inclined surface portion is fixed to the base 1. By doing so, the engaging portion 20 is pressed down by the handle 14 in the final stroke of use, and the pressing surface 6 is thereby raised.

Modification Example 1> In the first embodiment, the length of the pressing surface 6 is changed to the slope part 5 of one month.
Although it has been explained that the pressing surface 6 may be formed shorter than the gap or narrower, the pressing surface 6 may be divided into two or more pieces.A modification thereof is shown in FIGS. 13 and 14. Here, the pressing surface is divided into two pressing surfaces 6', 6'.In this case, the leading end of the staple is spread over two places by these pressing surfaces 6', 6' or by the inclined surface 6II.
, 6 flattened by I+. In the former case, lζcliber returns here and is pushed down again. In the latter case, move the flat table 9 while keeping the driver pressed down. Further, a wall 21 is formed in the center between the pair of inclined surface portions 5.5 on the base 1 side, and this wall 21 is formed during the final use process after the staple is bent by the inclined surface portions 5.5. This is to prevent the staple from falling backward. Conversely, these walls can also be formed as two walls 21' and 21+ on both sides of the flat table 9 in the first embodiment, as shown in FIG.

<Modification 2> As shown in FIG.
1.61.

Although this separation guide path G-1, 63 is constituted by three partition walls 22, it may be only the central partition wall. By forming this separation guide path 6-1, 6-4, even staples with loose legs can be bent obliquely and parallel to each other without colliding with each other, so that even a small amount of paper can be stapled and removed. Particularly in the case of a large stapler, this is useful because it allows the number of types of staples to be prepared for each number of sheets of paper to be reduced.

Further, as shown in FIG. 17, the same effect as described above can also be achieved by inclining the pair of inclined surface portions 5.5 in the lateral (vertical -15 = angular) direction of the longitudinal direction of the internal concave surface of the anvil.

The embodiments and modifications of the present invention have been described above according to the classification based on the relative movement between the pair of inclined surface portions and the pressing surface. Hereinafter, in order to explain the present invention in more detail, examples of the M structure of the present invention and its members will be individually described, and further examples of the pond will be described.

Δ8) Δ7) In the example, the rotating shaft 110 is close to the center of the pressing surface and automatically falls down...Figures 26A to 261) In this example, the rotating shaft 110 is offset, so the inclined surface member 102 has a strong force for falling outward, and when combined with the sliding surface 108, the inclined surface member 102 can be pushed outward by using the force of pushing down the driver or staple without operating the push-pull rod 109. .

・Figures 33A to 33C Here, to explain the timing of timely release, just before the staple is pushed out from the magazine with a driver (just before the tip of the staple is completely bent, or immediately after it is bent) , it is necessary that relative movement occurs between the inclined surface portion and the pressing surface. For this purpose, l
ζIt is best to detect this timing from the positional relationship between the handle provided on the clipper and the magazine (C
2-2-1) example]. However, when the paper thickness is the same, the positional relationship between the magazine and the base is the same when binding the paper, so this tie-1υ depends on the relationship between the handle and the base.
- It may be possible to detect timing [Example of C2-2-2)]. However, in this case, if the paper thickness is different, there will be some timing deviation.

Next, a preferred embodiment realized from the above structure and its members will be described.

[Example I-1] Example I-1 is the above 8]), C2-1-1,), C2
-2-2) This is a stapler that combines each side of El), F2), and Gl), and is shown in Figures 39A, 39B, and 4.0. In the figure, the engagement piece 130 of the operating rod 109 is engaged with the locking portion 142, thereby preventing the operating rod 109 from moving to the right. When the handle 114 is pushed up, the lever 115 is bent, and the force that moves the operating rod 109 to the right is stored. Further, when the handle 11/I is pushed down and the paper is almost stapled, the protrusion 140 of the handle 114 pushes down the engagement piece 130,
The lever 115 is disengaged from the locking portion 142 and the lever 115 is moved to the operating rod 1.
09 in the ij direction and the inclined surface portion 105 is moved to the right, the pressing surface 106 and the driver 104 come closer together, and the staple can be flattened and pressed. After the process is complete, the spring 109 returns everything to its original state.

[Example I-2] Example I-2 is the above-mentioned 83), C2-1-4), C2-
2-', +), E2), F3), and Gl), and is a stapler that combines each side of 4.1 A, 4.1. B
, shown in Figure 42. In the figure, the locking piece 130 engages with the portion 1/I2 of the lock 11, thereby preventing the operating rod 109 from moving to the left. When the handle 114 is pushed down, the spring 115 is compressed and stores a force to move the operating rod 109 to the left. When the handle 114 is further pushed down, the protrusion 140 engages the locking portion 142.
is pushed down, the locking piece 130 and the locking portion 142 are disengaged, and the operating rod 109 moves to the left.

This leftward movement causes the inclined surface members 1.02, 102 to move toward both ends via the crank 143. After finishing, the spring 120 returns it to its original state.

Furthermore, by adopting the example of E2) and F3), the tips of the staples cross each other diagonally to achieve this effect.

[Example ■-3] Example J-3 is the above-mentioned 88), C2-1, -3), C2
-2-1), E], ), F], ), G1. ) is a stapler that combines each side of 43A, 43B, 44
As shown in the figure. In the figure, the lower sliding surface 108' of the inclined surface member 102 rests on the sliding surface 108 of the push-pull rod 109. The inclined surface member 102 is rotatable around a shaft 143. The locking piece 130 engages with the locking portion 142, and the push-pull rod 10
9 is stopped from moving to the right. This embodiment does not employ a structure in which the push-pull rod 109 is directly moved.

When the handle 114 is pushed down, the driver 104 pushes down the staple, and the tip is bent by the anvil to staple the paper. At this time, the driver 104 tries to push down the inclined surface portion 102 via the staple. Inclined surface member 10
The rotation axis of 2 is located slightly toward the center, and this pushing down force acts on the inclined surface member 102 in the outward direction.
The sliding surface 108' pushes the sliding surface 108 and becomes a force that pushes the push-pull rod 109 to the right. The push-pull rod 109 is twisted due to the engagement between the locking piece 130 and the locking part 17I2, but when the staple has almost finished binding the paper, the protrusion 140 moves to the locking piece 1.
30 is pushed down to disengage it from the engagement part 142,
The push rod 109 moves to the right, the inclined surface member 102 falls outward, and the inclined surface portion 105 moves downward on both sides 1, and the spring 120 returns.

[Operations and Effects of Examples I-1 to I-3] The functions and effects of Examples 1-1 to I-3 will be described below.

(B) A3) Using Example ptS As shown in Figures 4.5A and 45B, the staple 7 is bent continuously from the tip on the double-sided slopes 105, 105, so that the pressing surface 106 has a mountain as shown by the imaginary line. 1. By moving the inclined surface member 102 away from the pressing surface 106 from its original position, the sheets 8, etc. to be bound can be bent in one direction. bend, driver 1
04 and the pressing surface 10G approach each other, and the staple 7 is crushed flat. At the stage shown in FIG. 45A, the tip of the staple 7 is facing the back side of the paper and is crushed as it is, so the tip of the staple 7 enters into the paper 8 and is safe.

(b) As shown in Figures 4.6 A and 4.6 B,
If there is a large amount of paper, the tip of the staple 7 will not reach the paper 8 and the tip will float, causing a danger of getting caught in the finger (see Section 46A).
From this state, the tip of the staple 7 is pressed toward the paper 8 (Figures 14 and 6B), so it is safe and never lifts from the paper.

(c) J shown in Figures 47A, 4.7B, and 4.7C: The foot length of staple 7 is a size that is larger than the appropriate size according to the thickness of the paper to be bound by υ paper thickness. It can also be bound easily. In Figure 4.7 A, the tip of the staple 7 is in contact with the back side of the paper 8, but
The upper part of staple 7 is not yet in contact with the paper. 47th B
In the figure, when the driver 104 is further pushed down,
The leading edge of the staple 7 enters the paper from below to above again.

In FIG. 47C, the driver 104 and the pressing surface 10G approach each other, and the staple 7 is flattened below the paper 8. In this case, although it is not an absolute requirement, it is convenient to use the example E2) for the inclined surface portion 105 and the example F3) for the pressing surface 106 because the tips of the staples can surely pass each other. E2) or F3) may be used alone or in combination.

(d) As shown in Figures 48A and 48B, the inclined surface member 1
In the case where the paper 8 moves obliquely downward, the staple 7 can be crushed without the paper 8 being bent.
