Abstract

<P>PROBLEM TO BE SOLVED: To provide a binding implement which can remove a locking state by a simple operation using a simple structure and a file equipped with this binding implement. <P>SOLUTION: The binding implement 1 comprises a base 2; a holding part 3 which can bind sheets P in such a way that sheets P are held between the base 2 and the part 3; an operating part 4 which can manipulate the holding part 3 between a binding state and a non-binding state; and a locking mechanism 6 which regulates the movement of the operating part 4 under the binding state. In addition, in the binding implement 1, the locking mechanism 6 can be manipulated between the locking state and the non-locking state by a specified manipulating force to be applied to the operating part 4. The operating part 4 is equipped with an operating part main body 41 and a locking release part 42 which can be manipulated to reset the locking state to the non-locking state 42. Besides, a first inclined surface part 42K is formed on the locking release part 42 and a second inclined surface part 21K almost in parallel with the first inclined surface part 42K is formed on the base 2. Thus the non-locking state is restored by the sliding movement of the first inclined surface part 42K over the second inclined surface part 21K while keeping a plane contact between the parts 42K and 21K, based on the manipulating force imparted only in a direction where the locking release part 42 is thrust. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a binding tool that can be unlocked by a simple operation, and a file to which the binding tool is applied.

  Conventionally, a base that is applied to a file or the like, a pressing portion that can be bound with a paper sheet held between the base, an operation portion that can operate the pressing portion in a binding state and a non-binding state, and binding 2. Description of the Related Art A lever-type binding tool that includes a lock mechanism that restricts movement of an operation unit in a state is known.

  As this type of binding tool, a force is applied in a direction in which the operation unit is pushed in from above, and a lock mechanism in a locked state is brought into an unlocked state by simultaneously applying a force in a direction in which the operation unit is moved in the horizontal direction. The thing comprised so that it can operate is mentioned (for example, refer patent document 1).

In addition, as an improved product, two different operation areas are provided in the operation unit, and an operation force is applied in the direction in which one of the operation areas is pushed in, so that the locked state is achieved and the other operation area is pushed in. One configured to be in an unlocked state by applying a force is considered (for example, see Patent Document 2).
Japanese Utility Model Publication No. 5-29905 (pages 1 to 3, FIGS. 1 and 2) Japanese Patent Laid-Open No. 2002-248883 (pages 1 to 4, FIGS. 1 and 2)

  However, as described above, the binding tool described in Patent Document 1 applies a force in a direction to push the operation unit from above and releases a force in a direction to move the operation unit in the horizontal direction when releasing the locked state. Since they must be given at the same time, there is a disadvantage that the operation direction becomes two directions and the simplicity of operation is impaired. In addition, when applying force in the direction to move the operation unit horizontally, the operation unit is unsafe, such as a finger coming off the operation unit, and the operation unit jumping up unexpectedly. It is.

  In addition, the binding tool described in Patent Document 2 can be operated in a locked state and an unlocked state only by applying a force in a direction in which the operation unit is pushed in from above, but in the vertical direction based on the force applied in the pushing direction. Since the lock mechanism can be operated in the locked and unlocked states by converting the slide operation into a left and right slide operation, the conversion may not be performed smoothly depending on the operation. Is lacking. In addition, the structure of an appropriate conversion mechanism for converting the slide operation is complicated, and the structure of the binding tool itself becomes complicated because of providing such a conversion mechanism, which leads to a complicated manufacturing process and an increase in cost. The problem that occurs. In addition, when operating from the locked state to the unlocked state, the operation unit that is substantially horizontal with respect to the base is further pushed downward to convert the vertical sliding motion into the horizontal sliding motion. Therefore, the degree of freedom of design is restricted to some extent, for example, a certain space for securing the stroke of the operation unit must be formed below the operation unit. Furthermore, since the thing of patent document 2 is what formed the holding | suppressing part using the synthetic resin material, at the time of disposal, you have to separate a holding | maintenance part and other members consisting of a metallic material, and it is troublesome. is there.

  The present invention has been made paying attention to such a problem, and a main purpose thereof is to provide a binding tool capable of releasing a locked state by a simple operation using a simple structure, and the binding tool. The purpose is to provide the prepared files.

  That is, the binding tool of the present invention is capable of operating between a base, a pressing portion that can be bound with a paper sheet held between the base, and the pressing portion between a binding state and a non-binding state. An operation unit and a lock mechanism for restricting movement of the operation unit in the binding state are provided, and the lock mechanism can be operated between a locked state and an unlocked state by a predetermined operation force on the operation unit. The operation unit includes an operation unit main body and a lock release unit that can be operated in the unlocked state by releasing the locked state. The first inclined surface is provided on the basis of an operating force applied only in a direction in which the lock releasing portion is pushed in, and the first inclined surface portion is provided, and the base is provided with a second inclined surface portion substantially parallel to the first inclined surface portion. There characterized in that it configured to be in the non-locked state by sliding while in surface contact with the second inclined surface portion. The file according to the present invention includes the binding tool as described above and a cover body to which the binding tool is attached.

  If it is such a binding tool or a file equipped with this binding tool, the first inclined surface portion slides on the second inclined surface portion only by applying an operating force in the direction of pushing the unlocking portion, and the locked state is released. Therefore, when releasing the locked state as in the past, it is not necessary to apply the force to push the operating part downward and the force to move in the horizontal direction at the same time. Can be released. Moreover, since the first inclined surface portion slides in a state of surface contact with the second inclined surface portion, the resistance generated during the unlocking operation can be effectively dispersed, and a smooth operation is possible, realizing a stable operation, The ease of operation can be effectively achieved. In addition, there is no need to provide a relatively complicated conversion unit such as a cam for converting the vertical sliding operation into the horizontal sliding operation in the operation unit, and a simple structure can be used. Contributes to simplification and cost reduction.

In particular, the operation unit is provided so as to be rotatable with respect to the base, and the operation unit is supported by the operation unit main body in a cantilevered manner so as to be rotatable with respect to the operation unit main body. If the lock release unit is configured to rotate with priority over the operation unit main body based on the operation force,
The first inclined surface portion can be reliably brought into surface contact with the second inclined surface portion, and the stability of the unlocking operation can be further improved.

  As a preferred embodiment of the locking mechanism, there is provided a first engagement portion provided on the operation portion main body and a second engagement portion provided on the base and engageable with the first engagement portion. And the first engagement portion and the second engagement portion are engaged with each other to enter the locked state, and the first inclined surface portion comes into surface contact with the second inclined surface portion based on the operation force. Thus, the relative position of the operation portion with respect to the base is displaced by sliding, so that the engagement between the first engagement portion and the second engagement portion is released to be in the unlocked state. What is configured is desirable.

  In order to realize a good locked state, the first engagement portion is a first engagement inclined surface portion provided in the operation portion main body, and the second engagement portion is provided in the base. A second engagement inclined surface portion that is substantially parallel to the engagement inclined surface portion, and the first engagement inclined surface portion and the second engagement inclined surface portion may be engaged with each other in the locked state.

  In addition, if an insertion port into which the second engagement inclined surface portion is inserted in the locked state is provided at a predetermined portion of the operation portion main body that is substantially continuous with the first engagement inclined surface portion, the operation portion main body is more reliably locked. Can do.

  As a specific embodiment, the first engagement inclined surface portion slides while making surface contact with the second engagement inclined surface portion based on an operation force applied only in the direction in which the operation portion main body is pushed, When the first engaging inclined surface portion gets over the second engaging inclined surface portion, the second engaging inclined surface portion is inserted into the insertion port, and the urging force is applied to force the operating portion to rise. A configuration in which the first engagement inclined surface portion is engaged with the second engagement inclined surface portion using the means so as to be in the locked state.

  The unlocking portion is attached to the inner surface side of the operation portion main body, and a window portion that can be exposed to the unlocking portion is provided at a predetermined portion of the operation portion main body, and the entire unlocking portion is provided through the window portion. Alternatively, one end portion of the unlocking portion is attached to the operation portion main body so that a part of the unlocking portion is exposed, and one end portion of the urging means that urges the force in the direction in which the operation portion rises is provided as one end portion of the unlocking portion. The end of the biasing means itself is not directly involved in the operation of the lock mechanism, and the operation feeling is not affected by the biasing force of the biasing means. is there.

  In order to simplify the manufacturing process, the window portion may be formed by cutting out a predetermined portion of the operation portion main body.

  Further, in order to easily form each inclined surface portion, the first inclined surface portion is formed by bending a part of the unlocking portion obliquely downward, and the second inclined surface portion is formed by partially forming the base. Anything cut and raised diagonally upward may be used.

  For the same purpose, the first engagement inclined surface portion is obtained by bending a part of the operation portion main body obliquely downward, and the second engagement inclined surface portion cuts and raises a part of the base obliquely upward. It is preferable that

  If the base, the pressing part, and the operation part are bent molded products made of a metal material, it is not necessary to disassemble the binding tool itself for each member at the time of disposal and dispose of it separately. In addition, it is excellent in durability as compared with a synthetic resin material.

  For example, if the cover body is a file made of a synthetic resin material, it is preferable that the cover body and the binding tool only need to be disassembled when discarded.

  As described above, according to the present invention, the first inclined surface portion can be slid on the second inclined surface portion only by applying an operating force in the direction in which the lock releasing portion is pushed, so that the locked state can be released. When releasing the locked state as in the prior art, it is not necessary to simultaneously apply a force for pushing downward to the operation unit and a force for moving in the horizontal direction, and the locked state can be released with an extremely simple operation. . Moreover, since the first inclined surface portion slides in a state of surface contact with the second inclined surface portion, the resistance generated during the unlocking operation can be effectively dispersed, and a smooth operation is possible, realizing a stable operation, The ease of operation can be effectively achieved. In addition, it is not necessary to separately provide a relatively complicated conversion part such as a cam for converting the vertical sliding movement into the horizontal sliding movement, for example, and a simple structure can be used. Contributes to process simplification and cost reduction.

  Next, an assembling procedure of the binding tool 1 composed of the above members will be described.

  First, as shown in FIG. 2 etc., the holding | suppressing part 3 is integrally attached to the base 2 via the connection shaft C of a substantially crank type. Specifically, one end portion of each connecting shaft C is inserted into the first bearing hole 31 formed in the holding portion 3, and the other end portion is inserted into the support wall 215 of the base body 21 and the upright wall 22 and the standing wall 22. It is inserted into the insertion hole 22a formed in the above. Note that, for example, assembly caulking is applied to both ends of the connecting shaft C to prevent the connecting shaft C from being pulled out. Next, the bending shaft 52 of the spring member 5 is inserted into the second bearing hole 32 formed in the pressing portion 3, and the coiled portion 51 is positioned between the support wall 216 and the standing wall 22. Subsequently, the operation portion main body 41 is arranged at both ends of the coil-shaped portion 51 so that the insertion holes 41N formed in the side surface portions 412 and 413 of the operation portion main body 41 are located. By inserting the fixing pin N so that the insertion holes 216 a and 22 a formed in the wall 22 are aligned, the base 2, the pressing portion 3, and the operation portion 4 are integrally attached via the spring member 5. Then, the unlocking part 42 is cantileverly attached to the operation part main body 41 according to the procedure described above, and the linear shaft 53 of the spring member 5 is connected to the extended end 413e of the operation part main body 41 and the hook part 421H of the unlocking part 42. To prevent the linear shaft 53 from being pulled out downward. Finally, the fixing pin N is prevented from falling off by using an appropriate fixing means such as caulking the tip of the fixing pin N protruding outside the upright wall 22 of the base 2. The binding tool 1 is assembled by the above procedure.

  Next, an operation method and operation of the binding tool 1 having such a configuration will be described with reference to FIGS. 7 and 8 are operation explanatory views showing a part of the cross section taken along the line BB in FIG. 6B.

  First, in a state in which the operation unit 4 is raised (FIGS. 5A and 7A), the user presses the pressing instruction unit including the protrusion 411a provided on the free end side of the operation unit main body 41. By doing so, the operation force F1 is applied in the direction in which the operation unit 4 is pushed into the base main body 21 side. Based on the operation force F1, the operation unit 4 rotates in a direction that is substantially horizontal with respect to the base main body 21, and the first engagement inclined surface portion 41K of the operation unit main body 41 gradually passes the second engagement of the base 2. It abuts on the engaging inclined surface portion 22K (FIG. 7B) and slides and moves obliquely downward along the shape of the second engaging inclined surface portion 22K while being in surface contact with the second engaging inclined surface portion 22K (FIG. c)). Along with this operation, the free end portion side of the operation portion 4 is displaced in a direction away from the standing wall 22 of the base 2. When the first engagement inclined surface portion 41K gets over the second engagement inclined surface portion 22K, the second engagement inclined surface portion 22K enters the insertion port 41I provided in the operation portion main body 41 from the distal end portion (same as above). (D), the operating portion 4 returns to the initial position, that is, the position contacting or approaching the standing wall 22 of the base 2 by the biasing force of the spring member 5, and the first engagement inclined surface portion 41K is the second. The surface comes into contact with the engaging inclined surface portion 22K ((e) in the figure). As a result, the movement of the first engagement inclined surface portion 41K by the urging force of the spring member 5 is restricted. As a result of the above operation, a locked state in which the rotational movement of the operation unit 4 upward is restricted. In conjunction with this operation, the lower end of the pressing portion 3 moves to a position in contact with or close to the base main body 21 to enter a binding state in which the paper sheet P can be bound.

  Moreover, what is necessary is just to press the press instruction | indication part which consists of the protrusion 421a provided in the protruding part 42R of the lock release part 42 of the operation part 4 from the upper direction in order to cancel | release a locked state (non-locked state). By pressing the pressing instruction unit, an operating force F2 is applied in a direction in which the lock release unit 42 is pushed into the base body 21 side. Based on this operating force F2, the unlocking part 42 rotates in the direction approaching the base body 21 with the mounting end as a fulcrum, and the first inclined surface part 42K of the unlocking part 42 is provided on the base body 21. Surface contact is made with the second inclined surface portion 21K (FIG. 8F). The height position of the operation unit main body 41 at this time has not changed from the height position in the locked state (FIG. 7E). That is, the unlocking unit 42 that has received the operating force F2 in the direction in which the unlocking unit 42 is pushed into the base main body 21 side is set to perform the rotating operation with priority over the operating unit main body 41. When the first inclined surface portion 42K slides obliquely downward along the second inclined surface portion 21K while sliding on the second inclined surface portion 21K by the operation force F2, the operation portion main body 41 is interlocked with the operation. Is moved obliquely downward, and the free end portion side of the operation portion 4 is displaced in a direction away from the standing wall 22 of the base 2 (FIG. 8G). When the lock release portion 42 is further pressed down, the first inclined surface portion 42K gets over the second inclined surface portion 21K, and at the same time, the second engaging inclined surface portion 22K comes off the insertion port 41I, and the first engaging inclined surface portion 41K and the first engaging inclined surface portion 41K The engaged state formed by bringing the two engaging inclined surface portions 22K into surface contact with each other is released, and the unlocked state is established (see FIG. 11H). At this time, the upright portion 21U of the base body 21 and the hanging portion 42D of the unlocking portion 42 are in surface contact. In this unlocked state, when the application of the operating force F <b> 2 to the unlocking portion 42 is stopped, the operating portion main body 41 and the unlocking portion 42 are raised by the urging force (restoring force) of the spring member 5. Then, the operation unit 4 returns to the initial position away from the base 2 (FIG. 7A). At that time, the first inclined surface portion 42K moves to the upright wall 22 side of the base 2 while being guided by the second inclined surface portion 21K. Along with this, the pressing portion 3 is also separated from the base main body 21 to be in a state where the binding state is released (non-binding state).

  As described above, the binding tool 1 in the file F according to the present embodiment includes the operation unit 4 including the operation unit main body 41 and the lock release unit 42 that can be unlocked and operated in the unlocked state. Yes, the unlocking portion 42 is provided with the first inclined surface portion 42K, and the base 2 is provided with the second inclined surface portion 21K substantially parallel to the first inclined surface portion 42K, and the operating force applied only in the direction of pushing in the unlocking portion 42. Based on F2, the first inclined surface portion 42K is configured to be unlocked by sliding while being in surface contact with the second inclined surface portion 21K. It is not necessary to apply a force for pushing the operation unit downward and a force for moving the operation unit simultaneously, and the locked state can be released by a one-touch operation. In addition, since the first inclined surface portion 42K slides in a state of being in surface contact with the second inclined surface portion 21K, the resistance generated during the unlocking operation can be effectively dispersed, and a smooth operation becomes possible and stable operation is achieved. This can be realized and the convenience of operation can be effectively achieved. Furthermore, it is not necessary to provide the operation unit 4 with a conversion unit having a relatively complicated structure such as a cam for converting a vertical sliding operation into a horizontal sliding operation, which contributes to simplification of the manufacturing process and cost reduction. .

  In addition, the operation unit 4 is provided so as to be rotatable with respect to the base 2, and the operation unit body 41 is supported by the operation unit body 41 in a cantilevered manner so as to be rotatable with respect to the operation unit body 41. The lock release unit 42 is provided, and the lock release unit 42 is preferentially rotated over the operation unit main body 41 based on the operation force F2 applied only in the direction in which the lock release unit 42 is pushed. Therefore, the first inclined surface portion 42K provided in the unlocking portion 42 can be reliably brought into surface contact with the second inclined surface portion 21K, and the stability and certainty of the unlocking operation can be effectively increased.

  In particular, the lock mechanism 6 includes a first engagement inclined surface portion 41K provided on the operation portion main body 41, and a second engagement inclined surface portion 22K provided on the base 2 and engageable with the first engagement inclined surface portion 41K. The first engagement inclined surface portion 41K and the second engagement inclined surface portion 22K are brought into a locked state by being engaged, and based on the operation force F2 applied only in the direction in which the lock release portion 42 is pushed. The first inclined surface portion 42K slides while being in surface contact with the second inclined surface portion 21K, thereby displacing the relative position of the operating portion 4 with respect to the base 2, and accordingly, the first engaging inclined surface portion 41K and the second engaging inclined surface. Since the engagement with the surface portion 22K is released and the unlocked state is established, the lock mechanism 6 can be configured using a simple structure, and the first inclined surface portion 42K is the second inclined surface portion 21K. Up By displacing the relative position of the operation unit 4 with respect to the base 2 in response to the sliding operation, the engagement state between the first engagement inclined surface portion 41K and the second engagement inclined surface portion 22K can be easily released. Yes, it is very convenient to use.

  Since the first engagement inclined surface portion 41K and the second engagement inclined surface portion 22K are in surface contact with each other in the locked state, for example, compared with the locked state in which the engagement claw and the engagement shaft are engaged. Thus, it is possible to ensure a large part of contact with each other and maintain a good locked state.

  Further, since the insertion port 41I into which the second engagement inclined surface portion 22K is inserted in the locked state is provided at a predetermined portion of the operation portion main body 41 that is substantially continuous with the first engagement inclined surface portion 41K, the second engagement inclined surface portion By inserting 22K into the insertion port 41I, it is possible to lock more reliably.

  Based on the operating force F1 applied only in the direction in which the operating portion main body 41 is pushed, the first engaging inclined surface portion 41K slides while being in surface contact with the second engaging inclined surface portion 22K, and the first engaging inclined surface portion 41K When the second engagement inclined surface portion 22K is overcome, the second engagement inclined surface portion 22K is inserted into the insertion port 41I, and the biasing force of the spring member 5 that biases the force in the direction in which the operation portion 4 rises is used. Since the first engagement inclined surface portion 41K is configured to be in the locked state by being brought into surface contact with and engaged with the second engagement inclined surface portion 22K, it can be locked by an extremely simple operation. Since the first engaging inclined surface portion 41K slides while contacting the second engaging inclined surface portion 22K, the second engaging inclined surface portion 22K functions as a guide portion that guides the movement of the first engaging inclined surface portion 41K. And move It is possible to increase the stability of the effect. Further, since each of the engaging inclined surface portions 41K and 22K slides while being in surface contact with each other, for example, when the engaging shaft slides while contacting the engaging claw and the engaging shaft gets over the engaging claw. Compared with the aspect in which the engagement shaft is engaged with the lower surface side of the engagement claw, the portion that contacts at the time of sliding movement does not concentrate at a specific location. As a result, even if each of the engagement inclined surface portions 41K and 22K is coated on the surface, it is difficult to remove the coating, which is preferable. Moreover, since each engagement inclined surface part 41K and 22K are closely related in the state which inserted the 2nd engagement inclined surface part 22K in the insertion port 41I, a more favorable locked state is realizable.

  The unlocking part 42 is attached to the inner surface side of the operation part main body 41, and a window part 41W that the unlocking part 42 can be exposed is provided at a predetermined portion of the operation part main body 41, and the unlocking part 42 is provided through the window part 41W. One end portion of the unlocking portion 42 is attached to the operation portion main body 41 so that the raised portion 42R of the spring is exposed, and one end portion of the spring member 5 is extended to a position passing through one end portion of the unlocking portion 42. Therefore, one end of the spring member 5 itself does not directly participate in the operation of the lock mechanism 6. As a result, the one end of the biasing means such as a spring member is extended to the free end of the operating portion, and the malfunction that occurs when the lock mechanism is configured from this one end and the engaging portion provided at the predetermined site, that is, When an error occurs in the size of the urging means for each lot, the urging force of the urging means is thereby different, and it is possible to solve the problem that it is impossible to give a uniform operational feeling to all products. Further, by extending one end portion of the spring member 5 to the attachment end portion of the unlocking portion 42, the unlocking portion 42 unexpectedly sinks below the operating portion main body 41 in a state where the operating force F2 is not applied. Depending on the setting, the raised portion 42R of the unlocking portion 42 is arranged so as to be substantially flush with the flat plate portion 411 of the operation portion main body 41 that is the peripheral portion of the window portion 41W through the window portion 41W. This also makes it possible to improve the appearance of the operation unit 4. If the urging force of the spring member 5 is weak, the raised portion 42R of the unlocking portion 42 may sink slightly below the flat plate portion 411 of the operation portion main body 41, and the appearance may be impaired. Even in the locked state, the first inclined surface portion 42K comes into contact with the second inclined surface portion 21K, and further sinking is restricted. At the time of unlocking, the operating force F2 applied only in the direction of pushing in the unlocking portion 42. Based on the above, as described above, the first inclined surface portion 42K slides while being in surface contact with the second inclined surface portion 21K, thereby entering the unlocked state. Thus, even when the biasing force of the spring member 5 is weak, there is no problem in the unlocking operation.

  In particular, since the window portion 41W is formed by cutting out a predetermined portion of the operation portion main body 41, the window portion 41W can be easily formed.

  Further, the first inclined surface portion 42K is formed by bending a part of the unlocking portion 42 obliquely downward, and the second inclined surface portion 21K is formed by partially raising the base 2 obliquely upward. The surface portions 42K and 21K can be easily formed.

  Similarly, the first engagement inclined surface portion 41K is obtained by bending a part of the operation portion main body 41 obliquely downward, and the second engagement inclined surface portion 22K is formed by cutting and raising a part of the base 2 obliquely upward. Therefore, each of the engaging inclined surface portions 41K and 22K can be easily formed.

  Since the base 2, the pressing portion 3 and the operation portion 4 are bent molded products made of a metal material, they are excellent in workability, can be manufactured relatively easily, and do not need to be separated and discarded at the time of disposal. Moreover, it will be excellent in durability as compared with a synthetic resin material. In addition, in the present embodiment, since the cover body H is the file F made of a synthetic resin material, the cover body H and the binding tool 1 can be easily separated only by disassembling the cover body H and the binding tool 1 at the time of disposal. It can be separated and is suitable.

  The present invention is not limited to the embodiment described in detail above.

  For example, as long as each inclined surface portion is configured to be slidable while being in surface contact with each other based on an operation force applied only in the direction in which the lock release portion is pushed in, the shape, dimensions, and the like are particularly limited. Of course not.

  Further, the lock mechanism only needs to be composed of two members that are engaged with each other. For example, the lock mechanism is composed of an engagement claw and an engagement hole, or includes an engagement claw and an engagement shaft. It may be configured.

  In addition, the binding tool may be provided along the left-right direction of the cover body, or may be applied to a file other than the illustrated file.

  In addition, the specific configuration of each part is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
