Description

  The present invention relates to a stapler, and more particularly to a stapler capable of switching between a use state in which materials to be bound can be bound together and a storage state advantageous for storage and carrying.

  Staplers for binding a plurality of sheets or the like (materials to be bound) are widely used in offices, educational sites, homes, and the like. In general, a stapler has a base body and a handle body which have a longitudinal direction and whose rear end portions are connected to each other so as to be rotatable, a spelling needle storage portion for storing the spelling needle, and a spelling needle as a base body. And a pressing blade portion that presses toward the side. The stapler is in a state in which the front ends of the base body and the handle body are separated from each other in a normal time when no external force is applied. That is, the stapler has a problem that it is inconvenient for storage and carrying because it takes a space and is distorted in a normal state. In order to solve such a problem, there is known a stapler capable of switching between a use state (a state including the normal time described above) in which the binding materials can be bound and a storage state advantageous for storage and carrying. Yes. Examples of such a stapler include a stapler described in Patent Document 1 and Patent Document 2.

  When the stapler of Patent Document 1 is carried or stored, when the lid is first lifted upward, the needle cutting tool and the splaying plate move together with the lid and move away from the needle box. After fully opening the body 180 degrees, the needle cutting tool is pushed with the fingertip, and the striation plate is operated in the forward direction. When the lid is moved down in this state, the needle cutting tool is positioned on the front side of the front wall portion of the needle box. The lid is completely covered with the needle box and is held in a vertically parallel state with the base body. In such a state, the stapler is carried in a pocket or a brush case.

  When the stapler of Patent Document 2 is carried or stored, first the lid side is pulled upward, and the needle cutting tool and the splaying plate inside thereof are moved upward from the needle box by the same movement of the lid. In this state, the slide lever is moved forward with the thumb. Then, the needle cutting tool of the splay plate also moves to a position outside the front wall portion of the needle box. Therefore, when the lid is lowered, the needle cutting tool descends to the front of the horizontal projection on the front wall portion of the needle box, so that the sliding lever is moved backward again. Then, the upper opening of the needle cutting tool engages with the horizontal protrusion on the front wall of the needle box and stops. Therefore, if the lid body and the base body are grasped, the entire body of the lid body, the needle box body, and the base body is in a vertically parallel state. In such a state, the stapler is put in a pocket or a brush case.

(Use state and storage state, and switching procedure)
A usage state in which the binding materials can be bound together, a storage state advantageous for storage and carrying, and a procedure for switching between the usage state and the storage state will be specifically described with reference to FIGS. FIG. 18 is a cross-sectional view along the front-rear direction in a state where no external force is applied in the usage state of the stapler according to one embodiment of the present invention. FIG. 19 is a cross-sectional view along the front-rear direction of the state in which the pressing portions of the handle body and the base body are pressed in the usage state of the stapler according to the embodiment of the present invention. FIG. 20 is a cross-sectional view along the front-rear direction in a state where the switch unit is slid forward in the process of switching the use state of the stapler according to the embodiment of the present invention to the housed state. FIG. 21 is a cross-sectional view along the front-rear direction showing the storage state of the stapler according to one embodiment of the present invention.

(Use state)
First, a case where an external force is not applied in the use state will be described with reference to FIG. In this case, the pressing blade portion 180 is positioned rearward of the magazine front plate 114 (the front plate of the binding needle storage unit 100) and the tip portion thereof is spaced apart from the needle positioned in the foremost row in a substantially vertical direction. Relative. The tip portion of the first restoring spring 160 formed on the sliding body 140 is received by the restoring spring lower receiving portion 121 formed on the first magazine side plate 116 and restored substantially upward. The distal end portion of the pressing blade portion 180 is spaced apart from the needles located in the foremost row.

  Next, a case where the pressing portions of the handle body 60 and the base body 20 are pressed to bind the materials to be bound in use will be described with reference to FIGS. 18 and 19. The pressing portion of the handle body 60 here is, for example, a front portion of the upper surface pressed by the right thumb (portion to which an external force indicated by an arrow in FIG. 19 is applied), and the pressing blade portion 180 in the front-rear direction. Or it is a part located in the vicinity. Moreover, the pressing part of the base body 20 is a front part of the bottom face pressed by the right index finger, for example, and is a part located in the pressing blade part 180 or its vicinity in the front-back direction.

  When the pressing portion of the handle body 60 is pressed substantially downward (that is, the base body 20 side when viewed from the handle body 60), the handle body 60 first rotates on a plane where the longitudinal direction and the thickness direction intersect. In conjunction with this, the magazine bottom plate 112 (the bottom plate of the staple storage unit 100) contacts the base bottom plate 22. From there, if the pressing is continued against the upward restoring force of the first restoring spring 160 and the second restoring spring 162 formed on the sliding body 140, the pressing blade portion 180 is moved to the magazine front plate 114 ( It is inserted into the hollow portion of the magazine 110 (the hollow portion of the staple needle storage unit 100) along the back surface of the front plate of the staple needle storage unit 100. At this time, the pressing blade portion 180 presses the needle located in the foremost row from above, thereby solving the state in which the needle and the other binding needle S are bound. As a result, the needle passes through the through hole formed in the front end portion of the magazine bottom plate 112. Further, the pressing blade 180 bends by sandwiching the needle with the clincher portion 52 in the vertical direction. In this way, the stapler 10 can bind the binding materials.

  Note that the stapler 10 in the state of FIG. 19 (the state in which the base body 20 and the handle body 60 overlap in the thickness direction) is removed when the external force applied to the pressing portions of the handle body 60 and the base body 20 is removed (for example, When the right thumb is released from the handle body 60 and the right index finger is released from the base body 20), the first restoring spring 160 and the second restoring spring 162 formed on the sliding body 140 are substantially upwardly restored. Thus, the state can be easily returned to the state shown in FIG. 18 (the state in which the above-described external force is not applied). Specifically, in the state of FIG. 19, the first restoring spring 160 formed in a substantially arc shape has its tip end abutted against the restoring spring lower receiving portion 121 formed on the first magazine side plate 116, It is bent so as to shrink in a substantially vertical direction. Therefore, the first restoring spring 160 tries to return to the original substantially arc shape, and thus the restoring force substantially upward is obtained. Similarly, the second restoring spring 162 formed in a substantially arcuate shape is bent so that the front end thereof is in contact with the front portion of the upper end surface of the second magazine side plate 122 and contracts in the substantially vertical direction. Therefore, since the second restoring spring 162 tries to return to the original substantially arc shape, the restoring force substantially upward is obtained.

  In the staple storage unit 100, the first magazine side plate engaging male portion 120 is engaged with the first base side plate engaging female portion 33, and the second magazine side plate engaging male portion 126 is the second. Engage with the base side plate engaging female portion 43. Thereby, the binding needle storage unit 100 is restricted from rotating with respect to the base body 20 in a plane where the longitudinal direction and the thickness direction intersect. In addition, the first magazine side plate convex portion 119 has a substantially hook-like tip portion of the first sliding restriction male portion 88 projecting from the handle body 60 in the use state. Engages with the tip portion. Further, the second magazine side plate convex portion 125 is formed in a substantially bowl shape of a second sliding restriction male portion 98 projecting from the handle body 60 in the use state. Engages with the tip portion. Thereby, the handle body 60 is restricted from rotating with respect to the staple storage unit 100 in a plane where the longitudinal direction and the thickness direction intersect.

(Procedure for switching from use to storage)
An example of the procedure for switching from the use state to the storage state will be described with reference to FIGS. First, by applying an external force as indicated by an arrow in FIG. 20, the switch portion 200 disposed at the rear end portion of the handle body 60 is slid forward in the top plate notch portion 64. Then, in conjunction with the sliding of the switch part 200, the sliding body 140 disposed on the inner surface of the handle body 60 and the pressing blade part 180 formed integrally with the front end part slide forward. Next, by pressing the pressing portion of the handle body 60 and the pressing portion of the base body 20 in a direction approaching each other, the handle body 60 is rotated in a plane where the longitudinal direction and the thickness direction intersect, and the base body 20 and the handle body are rotated. 60 is in a state of being overlapped in the thickness direction. Since the pressing blade portion 180 slides forward in advance as described above, the pressing blade portion 180 moves substantially downward along the front surface of the magazine front plate 114, and the tip portion thereof is the base bottom plate 22 (and the clincher plate). 50) or the vicinity thereof. The state at this time is the storage state (the state shown in FIG. 21).
