Description

Binding device fixing device, file and binding device fixing method

The present invention relates to a binding tool fixing device for fixing a binding tool for binding documents or the like on a file body, and a fixing method thereof.

Files that bind documents etc. are widely used in various situations such as businesses and homes. In general, the material of the cover body (file body) of this file is paper or resin. On the other hand, a binding tool for binding a document or the like may be made of metal or a relatively strong resin. Many. Therefore, there is a need to replace parts of the cover body and binding tool in response to damage caused by using the file. There is also a demand to separate the binding tool.

In order to meet these demands, a technique for separating a binding tool and a file main body in a file for binding a document or the like has been disclosed (for example, see Patent Document 1). In this technique, two engagement holes are provided in the spine portion of the file main body, and the binding tool is clamped on the file main body by an attachment means having a claw portion that engages with the engagement hole. The binding tool is fixed by engaging the claw portion with the engagement hole of the file body. Further, when the binding tool is removed from the file body, the engagement between the claw portion and the engagement hole is released.

Another aspect of the method for fixing the binding tool to the file body is also disclosed in, for example, Patent Document 2. In this technique, a fixing device for fixing is attached from the front side (outside) of the file body in a state in which the binding tool to be fixed is arranged on the file body. This attachment device has a pair of fixing engaging portions connected by a connecting portion that applies an elastic force. When fixing a binding tool, the user resists the elastic force between the engaging portions. Then, in the expanded state, the engaging portion is applied to the file main body and the binding tool. When the user releases the hand, a fixing force for fixing is generated between the engaging portion and the binding tool or the like by the elastic force. When the binding tool is removed from the file body, the user may again widen the engagement portion against the elastic force.

When attaching and detaching a binding tool for binding documents and the like to the file body, considering the convenience of the user, the operation for the attachment and detachment is completed by either the inner side or the outer side of the file body. Is preferred.

Further, if the user tries to attach / detach the binding tool by accessing from one side of the file body, there is no support for attaching / detaching the binding tool from the other side of the file body. By simplifying the configuration of the apparatus, the user's workability must be ensured. As a result, a configuration in which the fixing force of the binding device by the fixing device is not considered to be sufficient is often found in the related art. In other words, in the conventional configuration, when a document is bound against a library or the like, the fixing device may be detached from the file body due to the weight of the document or the fixing device may be damaged. However, when the document or the like is bound and dropped from the height of the table or the like, it cannot sufficiently withstand the impact force acting on the fixing portion of the binding tool, and thus has not been put into practical use.

In the present invention, in view of the above-described problems, a file having a sufficient fixing strength as a practical product can be fixed in a detachable manner only by working from one side of the file main body. It is an object of the present invention to provide a binding device and a file containing it.

In order to solve the above-described problem, the binding tool fixing device according to the present invention is provided for the file body side hole and the binding tool side hole provided to fix the binding tool and the file body. A configuration is adopted in which two engaging portions that enable engagement in different engagement directions are inserted, and the file main body or the binding tool can be engaged and released. The insertion direction of the two engaging portions is set from either the inside or the outside of the file body. By adopting such a configuration, both user operability and sufficient fixing strength can be ensured.

Specifically, the binding tool fixing device according to the present invention uses the fixing hole provided in the binding tool for binding documents and the like, and the file side hole provided in the file body, and uses the binding tool and the file. A binding device fixing device for fixing a main body, a fixing device main body portion disposed in a file main body, and a communication hole provided in the fixing device main body portion and formed by overlapping a fixing hole portion and a file side hole portion A pair of insertion portions to be inserted into the communication hole, and when the pair of insertion portions are inserted into the communication holes, a member on the back side in the insertion direction of the insertion portion of the file main body and the binding tool is used as an engaged member. A first engagement portion and a second engagement portion provided in each of the pair of insertion portions, the engagement member being capable of engaging and releasing the engagement; And the 1st engagement direction which is an engagement direction of the to-be-engaged member engaged by the 1st engagement part is the engagement direction of the to-be-engaged member engaged by the 2nd engagement part. It is set to be different from the two engagement directions.

In the binding tool fixing device according to the present invention, the pair of insertion portions are inserted into the communication holes formed by overlapping the file side hole provided in the file body and the fixing hole provided on the binding tool side. Is done. In the inserted state, the first engagement portion and the second engagement portion provided in each insertion portion are located on the back side in the insertion direction of the insertion portion of the file body and the binding tool (the book). The engaged member according to the invention is arranged in a state where it can be engaged and released. Then, when each engaging portion is engaged with the engaged member, the binding tool and the file main body are fixed by the engaging portion and the fixing device main body of the binding fixing device, When the engaged state is released from the engaged state, the fixed state between the binding tool and the file body is released. As a result, the binding tool can be freely attached to and detached from the file body. Regarding the formation of the communication hole, the file side hole portion and the fixing hole portion may have different shapes. In short, the insertion portion passes through the hole portion on the fixed member side and is engaged by the engaging portion. It is sufficient that both hole portions are continuous so that the engagement with the combined member is possible.

Here, the access to the communication hole in the above-mentioned binding tool fixing device is possible from either the inside or the outside of the file body. That is, when attached to the inner side of the binding tool arranged inside the file body, a pair of insertion portions are inserted in the order of the fixing hole portion and the file side hole portion, and are provided in each insertion portion. The first and second engaging portions engage with the file main body as the engaged member. When attached to the outside of the file, the pair of insertion portions are inserted in the order of the file side hole portion and the fixing hole portion, and the first and second engagement portions provided in each insertion portion are engaged. Engage with a binding tool as a member. Thereby, the user operability is significantly improved. More preferably, the user should fix the binding tool from the side where the binding tool is installed, that is, from the inside of the file body. This is because the back cover part of the file body is often provided with a cover for the headline (usually a transparent resin cover etc. so as to be visible to the headline user). This is because it is often difficult for the user to perform the work for fixing the binding tool.

And by setting so that the 1st engagement direction which is an engagement direction of the to-be-engaged member by engagement of these 1st engagement parts and the 2nd engagement parts may differ from the 2nd engagement direction. It is possible to sufficiently resist the external force that attempts to release the engagement by each engagement portion, and to more reliably fix the binding tool and the file body. In particular, in a file that binds documents and the like, external force may be applied from various directions depending on the use state of the user. Therefore, the fixing having a plurality of different engagement directions as in the binding device fixing device according to the present invention is possible. By configuring with the device, it is possible to sufficiently secure the fixing strength of the file as a practical product.

Note that each engaging portion may be designed to engage with any portion of the engaged member. For example, when the binding device fixing device is a mechanism for fixing by accessing from the inside of the file, and the file side hole portion is a through hole, the pair of insertion portions is the binding portion side hole portion, the file side hole portion It can be designed to be inserted in order and engage with the file body in a state where each engaging portion reaches the outside of the file body. Further, in a state where the pair of insertion portions are inserted into the file side hole portion, each engaging portion may be engaged with the file main body in the middle portion of the file side hole portion. In summary, the engagement of each engaging portion with the engaged member is important in that the insertion of the pair of insertion portions is performed from one side of the file body, Any place may be used as long as the binding tool is fixed to the file body. Therefore, the hole on the engaged member side does not have to be a through hole. For example, the file-side hole including a recess and an engaged space with each engaging portion provided in communication with the recess. It can also be applied to a file body provided with.

Further, the above configuration can realize attachment and detachment of the binding tool to the file in which no member remains on the outside of the file (a heading part covered with a transparent resin sheet may be provided). Very good operability can be obtained, such as no parts of the fixing device remain in the headline where it is difficult for the user to put hands.

Further, the first engagement direction and the second engagement direction may be opposite to each other along the surface of the engaged member. Thus, by making both engagement directions reverse, fixing by engaging the first engagement portion and the second engagement portion with respect to the external force acting when the binding tool and the file body are fixed. The state can be effectively maintained. That is, even when a force in the direction of loosening (releasing) the engagement is applied to one of the engaging portions, a force in the direction of strengthening (tightening) the other engaging portion. This solves the problem that prevented the pair of insertion parts from being removed from the file side hole, which prevented the practical application of the configuration for attaching and detaching the binding tool to the file main body from one side. It becomes possible.

Preferably, the file side hole is provided in the spine portion of the file body, and the first engagement direction and the second engagement direction are set to be opposite to each other along the vertical direction of the spine portion. . When a user binds a document or the like to a binding tool, one of the possibilities that a strong external force acts on the fixed portion between the binding tool and the file body is that the file in which the document or the like is bound is The case where it falls to the floor etc. is considered. When such a drop form is considered, the fixed force between the binding tool and the file main body is maintained by securely receiving the external force acting by the drop at the first engagement portion and the second engagement portion, and the binding tool. It becomes possible to avoid breakage of the fixing device.

In addition, when a file is stored in a library or the like, the weight of the document or the like bound to the binding tool works in the direction of pulling the binding tool away from the file body, so it is conventional to perform attachment / detachment by operating only from one side of the file In this fixing mechanism, the engaging part may fall out from the file side hole, and practical use of such a fixing mechanism with operability was hindered. Even when a force in the disengagement direction is applied to one engaging portion of the pair of insertion portions, a force in a direction that strengthens the engagement is applied to the other insertion portion. Therefore, the engagement force with the file main body by the “pair of insertion portions” is sufficiently maintained, and the binding tool is separated from the file main body without permission (unintentionally by the user) while being stored in the library or the like. This prevents the problem that the documents and the like stored in the binding tool are scattered, and makes it possible to put to practical use a mechanism that attaches and detaches the binding tool and the file main body only from one side.

In order to put such a file into practical use, not only the performance of the binding fixing device but also the performance of the entire file needs to be equal to or higher than that of a file having other conventional fixing mechanisms. For conventional files with the same capacity for storing documents, etc., it is necessary to have the same spine width. That is, the width of the back cover portion of the file body is narrower than the height in the vertical direction. Therefore, by setting the engagement direction as described above, it is sufficient to withstand practical use with a degree of freedom in setting the size and shape of the engagement portion compared to the case where the engagement direction is the width direction. Design can be performed. Also, if the engagement direction is the width direction of the back cover, the engagement / release operation of each engagement portion with the engaged member may be the width direction of the back cover. Is set to a minimum, so that the operability is deteriorated. In the above configuration, the operability of the attaching / detaching operation can be sufficiently secured.

Here, in the binding device fixing apparatus described above, preferably, in a state in which the engagement of the first engagement portion and the second engagement portion with the engaged member is released, the pair of insertion portions has the communication holes. On the other hand, it can be inserted from the inside or outside of the file body, and can be extracted from the inside or outside of the file body. By linking the disengaged state of the first engaging portion and the second engaging portion and the state in which the pair of inserting portions can be freely inserted and removed, the operability by the user of the binding device fixing device according to the present invention is improved. To do. In particular, the binding tool fixing device performs the attaching / detaching operation of the binding tool by access from only one side of the file main body, so that improvement in workability greatly contributes to the user's profit.

Here, in the binding tool fixing device described above, the fixing device main body has a first slide member and a second slide member that slide relative to each other, and one of the pair of insertion portions is a first slide. The other insertion part may be provided on the second slide member. At this time, when the first slide member and the second slide member reach the engagement position by relative sliding, the engagement state between the first engagement portion and the engaged member by the second engagement portion is formed. When the first slide member and the second slide member reach the disengagement position by relative sliding in the opposite direction to the slide that reaches the engagement position, the first engagement portion and the second engagement portion The engaged state with the engaged member due to is released.

In this way, by configuring the fixing device main body portion with the first slide member and the second slide member, the user performs the slide operation of both the slide members, thereby engaging the first engagement portion and the second engagement portion. The combined state is formed and released. Here, in order to establish the engagement state and the release thereof, the first slide member and the second slide member are relatively slid between the engagement position and the engagement release position, and the slide member Slides are also referred to herein simply as “relative slides”. Therefore, a user who wants to fix the binding tool to the file body can communicate with the pair of insertion portions of the binding tool fixing device formed by overlapping the file side hole portion and the fixing hole portion from one side inside or outside the file body. What is necessary is just to insert in a hole and to perform the said relative slide further, and the operation | work imposed on a user becomes very simple, and fixation of the strong binding tool by a 1st engaging part and a 2nd engaging part is implement | achieved.

Then, the sliding direction of the first slide member in the relative slide reaching the engagement position matches the first engagement direction, and the slide direction of the second slide member in the relative slide reaching the engagement position is the same as the first slide direction. The two engagement directions may be set to coincide. By engaging the sliding direction of each slide member with the engagement direction according to the engagement state of the engagement portion, the engagement portion is engaged with the engaged member at the time of fixing or releasing the binding tool. This makes it easier to recognize the release and its release, thereby contributing to the improvement of workability.

Here, in the binding device fixing device having the first slide member and the second slide member, when the first slide member and the second slide member reach the engagement position by relative sliding, a predetermined slide restriction position A lock member that restricts relative sliding between the first slide member and the second slide member may be further provided.

As described above, the first slide member and the second slide member are relatively slid to fix the binding tool and the file main body by the engagement of the engagement portions. Here, in order to more reliably maintain the engagement by each engagement portion, the lock member is provided, and the operation of the lock member is performed by the user as in the case of insertion of the insertion portion and relative sliding. In consideration of easiness, it is performed by the user accessing from one of the inside and the outside of the file body that performs the sliding operation of each slide member. Specifically, after the user slides each slide member relative to each other and engages the engaged member by each engaging portion, the lock member reaches a predetermined slide restriction position where the relative slide is restricted. By tightening, the relative slide of the slide member is limited, and thus the engagement by each engagement portion is reliably maintained.

As an example of the lock member, the following form may be mentioned. For example, the lock member is connected to at least one slide member of the first slide member and the second slide member via a hinge connection portion, and the hinge connection portion is rotated by the hinge connection portion. It is a possible member. When the first slide member and the second slide member reach the engagement position by relative sliding, a gap corresponding to a predetermined slide restriction position is formed between the both slide members, and the lock member is rotated and moved. The relative sliding of the slide members may be limited by closing the gap. In addition to the form in which the lock member is connected so as to be able to rotate and move relative to the slide member, the form of the lock member connected to the slide member in a state where linear relative movement is possible is also possible It can be adopted. Furthermore, the lock member may be separated from the slide member and configured as an independent member. Even in such a case, the independent locking member is set so as to reach the gap from one of the inner side and the outer side of the file main body and close the gap.

Here, in the file having the above-described binding tool fixing device, when the first slide member and the second slide member reach the disengagement position, the disengagement position maintaining unit that maintains the relative positional relationship between the slide members. Further, it may be provided. By having the engagement release position maintaining portion in this way, it is possible to maintain the relative positional relationship between the first slide member and the second slide member that are in the engagement release position. As a result, the relative positional relationship between the pair of insertion portions provided with the first engagement portion and the second engagement portion is not affected by the posture or the like of the binding device fixing device during the fixing operation of the user. Therefore, the pair of insertion portions can be smoothly inserted into and removed from the communication holes formed by overlapping the file side hole portion and the fixing hole portion. .

Further, when the first slide member and the second slide member reach the engagement position, an engagement position maintaining unit that maintains the relative positional relationship between the slide members may be further provided. Thus, by having an engagement position maintenance part, it becomes possible to maintain the relative positional relationship of the 1st slide member and 2nd slide member in an engagement position. As a result, the fixed state of the binding tool and the file main body by the engagement of the first engaging portion and the second engaging portion can be smoothly performed without being affected by the posture of the binding tool fixing device at the time of the user's fixing work. It becomes possible to form. In particular, it is useful to maintain the relative positional relationship by the engagement position maintaining portion in order to secure the gap formed when trying to limit relative sliding using the lock member.

In the binding device fixing device according to the present invention, it is not always necessary to provide the engaging position maintaining unit and the disengaging position maintaining unit at the same time, but to include one of the necessary maintaining units in consideration of user needs. May be.

And about the structure of an engagement position maintenance part and an engagement release position maintenance part, the example shown next is given. For example, the first slide member has a maintenance groove formed along the relative slide direction of the slide, and a projection that divides the maintenance groove into two maintenance regions, and the second slide member The slide member is formed along a relative slide direction of the slide, and has an accommodating projection that can be placed over any of the two maintenance areas by overcoming the projection. Then, at this time, the engagement position maintaining portion is configured such that the housing projection portion is accommodated in one of the two maintenance regions, so that the first slide member and the second slide member are both in the engaged position. The relative position relationship between the slide members is maintained, and the disengagement position maintaining portion is disengaged between the first slide member and the second slide member by accommodating the accommodation protrusion in the other of the two maintenance regions. You may make it maintain the relative positional relationship of both slide members when it arrives at a position.

That is, according to the relative movement relationship between the maintenance groove provided on the first slide member side and the housing projection provided on the second slide member side, the protrusion in the maintenance groove is moved relative to the engagement position maintenance part. By setting the boundary between maintaining the positional relationship and maintaining the relative positional relationship by the disengagement position maintaining unit, relative sliding of the first slide member and the second slide member is performed. Accordingly, the relative position relationship is maintained by the engagement position maintaining portion and the engagement release position maintaining portion by accommodating the accommodation protrusion in any one of the maintenance regions divided into two.

Further, in the file having the above-described binding tool fixing device, when the first slide member and the second slide member are out of the disengagement position, both the slide members are restricted within a predetermined movement range. You may make it provide the relative movement permission part which forms the relative positional relationship of these both slide members so that a relative movement is accept | permitted.

By having the relative movement allowance portion in this way, when both slide members are in a position disengaged from the disengagement position, the relative positional relationship between both slide members is not maintained, and the relative slide of both is allowed. . Therefore, a user who uses a binding tool fixing device having both slide members to fix the binding tool and the file body engages the relative positional relationship between both slide members as soon as the user touches the binding tool fixing device. It can be easily determined whether or not it is in the release position. Then, if necessary, by performing relative sliding so that both slide members are positioned at the disengagement position, it is possible to realize a smooth fixation between the binding tool and the file body. Moreover, it becomes possible to maintain the relative positional relationship of the 1st slide member in a disengagement position, and a 2nd slide member by setting it as the structure which has the said disengagement position maintenance part.

And about the structure of a disengagement position maintenance part and a relative movement permission part in the case of said file, the following example is given. For example, the first slide member has a groove formed along the slide direction of the relative slide, and a first protrusion that divides the groove into two regions, and the second slide member is relatively And a second protrusion that is formed along the sliding direction of the slide and that fits in either of the two regions over the first protrusion. At this time, the disengagement position maintaining unit is configured such that both slides when the first slide member and the second slide member reach the disengagement position by accommodating the second protrusion in one of the two regions. The relative positional relationship of the members is maintained, and the relative movement allowing portion accommodates the second protrusion in the other of the two regions, and enables movement of the second protrusion in the other region. Thus, both slide members may realize relative movement in a limited state within a predetermined movement range.

That is, according to the relative movement relationship between the groove portion provided on the first slide member side and the second protrusion portion provided on the second slide member side, the first protrusion portion in the groove portion is relatively moved by the disengagement position maintaining portion. The relative sliding of the first slide member and the second slide member is performed by setting the boundary between the maintenance of the positional relationship and the switching of the relative movement permission by the relative movement permission unit. As a result, when the second protrusion is within one of the two regions, the relative positional relationship between the slide members can be maintained and the relative movement within a limited predetermined range can be achieved. .

Moreover, in the above-described binding tool fixing device, the first slide member further includes an operation unit for the user to slide relative to the second slide member, and an obstructed unit provided in the vicinity of the operation unit. In the relative slide, the second slide member further has an operation portion of the first slide member in which the slide members reach either the engagement position or the disengagement position. When the distance with respect to the end portion arranged in the vicinity of the end portion of the two slide members becomes a close state, it reaches a position overlapping the inhibited portion with respect to the inhibited portion, and the first slide member is displaced upward. In contrast, it may have an inhibition part capable of inhibiting the displacement via the inhibited part.

In the above-described binding tool fixing device, when the operation portion of the first slide member is brought into the close state in the relative slide, the obstructed portion and the obstructed portion are mutually displaced with respect to the upward displacement of the first slide member. Due to the obstructing positional relationship, forcing the user to operate both slide members upward relative to the user operating the operating unit for relative sliding is limited by the presence of the inhibited part and the inhibiting part. It is possible to explicitly let them know. That is, when both slide members are in the engaged position or the disengaged position, if the user attempts to forcibly move them upward, the obstructing portion comes into contact with the obstructed portion. The user knows that the forced relative movement is not appropriate. As a result, the user can be guided to an operation for an appropriate relative slide. Moreover, you may comprise so that an inhibition part may not only prevent the movement to the said direction of the to-be-inhibited part side but to prevent. If comprised in this way, it can prevent that the force provided to the incorrect direction from the user exerts a bad influence on the 1st slide member.

And about the said to-be-inhibited part and the inhibition part, the following example is given. For example, the operation portion of the first slide member is provided at the end portion of the first slide member that does not contact the second slide member, and the inhibited portion is provided adjacent to the operation portion. The inhibition portion may be provided at an end portion of the second slide member that faces the first slide member. Note that the specific configuration of each part is not limited to this form, and preferably is provided in a place where the presence of the slide member is not easily affected and the presence of the slide is easily notified to the user.

Here, in the above-described binding tool fixing device, the first slide member performs relative sliding along the upper surface of the second slide member, and a part of the second slide member is the upper surface of the first slide member. Both slide members may be configured to cover a part of the first slide member and limit upward displacement of the first slide member. That is, the first slide member and the second slide member are configured to overlap each other above the binding device fixing device that is different from the slide direction of the relative slide, so that the user can perform the relative slide operation. It is possible to prevent the first slide member positioned on the upper side from warping and to promote relative sliding more smoothly. That is, such overlapping of the first slide member and the second slide member greatly contributes to improvement of user workability.

And about the overlap of the 1st slide member and the 2nd slide member in the said binding tool fixing device, the following example is given. For example, the first slide member has a notch in a part of the side along the slide direction of the relative slide, and the second slide member has a first slide member on the upper surface of the second slide member. In order to slide, it has the slide hollow part which accommodates this 1st slide member, and the protrusion piece which protrudes in the slide hollow part. The projecting piece covers the part of the upper surface of the first slide member by being accommodated in the notch in a state where the first slide member is accommodated in the slide recess, and the notch The inside may be freely displaceable according to a relative slide. With such a configuration, it is possible to realize the relative slide of both slide members and the overlap of both slide members above the binding device fixing device.

Further, in the above-described binding tool fixing device, when the member sandwiched between the fixing device main body portion and the engaged member among the file main body and the binding tool is a fixed member, the fixing device main body portion further includes: When the first engagement portion and the second engagement portion are in a state in which the engagement with the engaged member is released, the first engagement portion and the second engagement portion may have a positioning portion that positions the relative position of the pair of insertion portions with respect to the fixed member. Good. That is, even in the binding tool fixing device that engages and releases the first engagement portion and the second engagement portion by an operation other than relative sliding, the engagement by each engagement portion is performed for the same reason as described above. A positioning part that positions the relative position of the pair of insertion parts with respect to the member to be fixed in a state where the engagement is released is useful.

In particular, in the above-described binding tool fixing device, the first slide member is sandwiched between the fixed member to be arranged, that is, the member to be engaged by the engaging portion and the binding tool fixing device. The first positioning protrusion on the back surface that contacts the fixing member (binding tool or file body), and the second slide member contacts the fixed member (binding tool or file body) arranged in the same manner as described above. In the case where the second positioning protrusion is provided on the back surface, when the first slide member and the second slide member are arranged on the fixed member, the first positioning protrusion is formed in the positioning hole provided on the fixed member side. When the first positioning projection and the second positioning projection come into contact with the edge of the positioning hole by relative sliding of the slide members, the first slider is accommodated. De member and the second sliding member may be configured to be positioned in the disengaged position. In addition, a hole portion may be provided on the slide member side, and positioning may be performed by contacting the protrusion to the edge of the hole portion as described above with respect to the protrusion provided on the binding tool side. Further, the first positioning protrusion and the second positioning protrusion may be inserted into the hole so as to be positioned in the same manner, or may be configured to be inserted into different holes.

That is, in the binding tool fixing device, the first slide member and the second slide member that perform relative sliding are provided with positioning projections (first positioning projection and second positioning projection) or holes, respectively. The relative positional relationship between the slide members is determined by the contact relationship between the projections (holes) and the positioning hole (projection) on the fixed member side. In particular, when the positioning projection and the positioning hole come into contact with each other, the relative sliding operation is restricted, and as a result, the positions of both slide members are automatically specified halfway to the disengagement position. This disengagement position is also a position where the user wants to remove the pair of insertion portions from the communication hole. Therefore, when the positions of both slide members are automatically specified by the positioning protrusions and the positioning holes as described above, the user's extraction operation can be performed relatively easily.

A file including the above-described binding tool fixing device is also an aspect of the present invention. That is, the file according to the present invention is a file including the binding tool fixing device, the binding tool, and the file main body up to the above, and the fixing device main body portion and the engaged member of the file main body and the binding tool. A member sandwiched between them is a file to be fixed to the engaged member by a binding device fixing device as a fixed member. As described above, the file is formed by fixing the engaged member and the fixed member by the binding device fixing device, but may include configurations other than these configurations.

Further, in the file having the above-described binding tool fixing device, the base member on which the first slide member and the second slide member are disposed when the binding member is in contact with the inside of the fixing member and the binding tool is fixed. And a protruding portion that is provided on the base member and extends along the sliding direction of the relative slide by the first slide member and the second slide member. Also, a slide recess may be provided that is provided on at least one of the first slide member and the second slide member, fits into the projecting portion, and slides on the projecting portion during relative sliding.

When the insertion portion described above is inserted into the communication hole formed by the fixing hole portion and the file side hole portion from the inside of the file body, each engagement portion is a file body corresponding to the engaged member; Thus, the binding tool is clamped and fixed between the binding tool fixing device and the file body. At this time, the 1st slide member and the 2nd slide member which comprise a fixing device main-body part are arrange | positioned on the base member of a binding tool, and the insertion to each communicating hole mentioned above and subsequent relative slide are performed. . Here, the protrusion provided on the base member and the slide recess provided on at least one slide member are fitted, and the slide recess may slide on the protrusion in relative sliding. It is possible. That is, the projecting portion is configured to play a role as a guide for relative sliding of both slide members, and as a result, the user can smoothly engage and release the engaging portion. Further, when both the slide members are arranged on the binding tool, the fitting between the slide concave portion and the projecting portion is useful for positioning the arrangement location.

And it is a positioning piece orthogonal to the insertion piece 22b, and has a positioning piece 22c as a positioning flat plate portion. Further, as described above, the engaging claws other than the engaging claws 22 have the same configuration as the engaging claws 22, and although reference numerals are not shown in the drawing, In each of 42 and 43, when an engagement piece, an insertion piece, and a positioning piece are indicated, a, b, and c are appended to the reference numbers of the respective engagement claws.

In the engagement claw 22 configured as described above, when the engagement claw 22 is relatively approached in the direction of the binding tool 60 on which the engagement claw 22 is stacked and the file main body 80, the engagement piece 22a and the first slide member 10 (in particular, The binding tool 60 and the file main body 80 are accommodated between the horizontal frame 14a), and as a result, the engaging claw 22 engages the binding tool 60 and the file main body 80, thereby fixing the binding tool 60. Will do. Here, an opening portion between the engagement piece 22a and the first slide member 10 in the engagement claw 22 (a portion facing the insertion piece 22b) is referred to as an “opening portion” of the engagement claw 22, and the opening portion. The binding tool 60 or the like is accommodated toward the insertion piece 22b from the side, and the engagement direction (direction from the insertion piece 22b toward the opening) by the locking claw 22 when the binding tool 60 or the like is engaged is set in the present invention. This “engagement direction” is defined. Further, when the binding tool 60 or the like is engaged by the engagement claw 22, the positioning piece 22c guides the engagement claw 22 to a predetermined position where the engagement claw 22 should be engaged. The fixing of the binding tool 60 by the fixing device 1 will be described in detail later.

Further, the engagement directions of the engagement claws 22 and 23 of the first slide member 10 are the same, and the engagement directions of the engagement claws 42 and 43 of the second slide member 30 are the same. The engaging direction of 23 is opposite to the engaging direction of the engaging claws 42 and 43. Then, in the fixing device 1, as shown in FIG. 3B, a pair of engaging claws are formed in a state where the engaging claws 23 and the engaging claws 42 are opposite to each other. A pair of engaging claws are formed in a state in which the claw 22 and the engaging claw 43 are opposite to each other.

Here, in each pair of engaging claws, the distance between one engaging claw and the other engaging claw (more precisely, the interval between the insertion pieces of both engaging claws. ) Varies with relative sliding of the first slide member 10 and the second slide member 30 (note that the state shown in FIGS. 3A and 3B shows the state where the distance between the claws is widest, which will be described later. Corresponds to “engaged state”). Then, in a state in which the distance between the engaging claws is widest, the lock members 36 and 37 provided on the second slide member 30 side are rotationally displaced, whereby a space formed between the engaging claws ( Hereinafter, a part or all of the lock members 36 and 37 enter the “insertion space.” As a result, the relative slide of the first slide member 10 and the second slide member 30 is limited, The “state” will be maintained. Further, when it is desired to perform relative sliding again, the lock members 36 and 37 can be removed from the space formed between the engaging claws by rotationally displacing the lock members 36 and 37 in the opposite direction. .

Here, a detailed configuration of the lock members 36 and 37 will be described with reference to FIG. 3A. Since the lock members 36 and 37 have the same configuration, only the lock member 36 will be described as a representative. The lock member 36 is a plate-like operation plate portion 36d that is hinged to the base portion 31 of the second slide member 30, and a plate-like member that stands vertically with respect to the operation plate portion 36d. The plate-like flat surface is a first plate portion 36a extending in the width direction of the base portion 31 and a plate-like member standing vertically to the operation plate portion 36d, and is formed with respect to the first plate portion 36a. Even with respect to the operation plate portion 36d, the second plate portion 36b and the first plate portion 36a that are orthogonal to each other are on the plate-like plane opposite to the connecting portion with the second plate portion 36b. And a semi-cylindrical contact portion 36c so as to be vertical. Further, as described above, the lock member 37 has the same configuration as that of the lock member 36, and reference numerals are not shown in the drawing. In the case of referring to the part, the contact part, and the operation plate part, the respective reference numbers are 37a, 37b, 37c, and 37d. The functions of the lock members 36 and 37 will be described in detail later.

Further, as shown in FIG. 3B, in the fixing device 1 in which the first slide member 10 and the second slide member 30 are combined, the positioning protrusions 21 and 41 provided on the back side of each slide member are arranged adjacent to each other. Will be. As the first slide member 10 and the second slide member 30 slide relative to each other, the relative positional relationship between the positioning projection 21 and the positioning projection 41 changes. And these protrusion parts have the function which positions both slide members by displacing in the positioning hole part 64 by the side of the binding tool 60 as mentioned above, but this point is mentioned later.

Further, as shown in FIG. 3B, on the back side of the fixing device 1, the slide recess 24 of the first slide member 10 and the slide recess 46 of the second slide member have the same center axis and are aligned in a line. . As for these slide recesses, the relative positional relationship between the slide recess 24 and the slide recess 46 changes as the first slide member 10 and the second slide member 30 slide relative to each other.

Here, in the fixing device 1, the state of the pair of engaging claws described above varies depending on the positions taken by both slide members by the relative sliding of the first slide member 10 and the second slide member 30, and as a result, By changing the engagement state of the binding tool 60 and the like via the respective engaging claws, the binding tool 60 is fixed or removed. Therefore, in order to help understanding of the structure of the fixing device 1 according to the present invention and the file using the same, first, the engagement state in the fixing device 1 is illustrated based on FIGS. 4A and 4B, and the disengagement state is illustrated. A description will be given based on 5A and 5B.

In the engaged state of the fixing device 1, as shown in FIG. 4A, the relative position relationship in which the operation unit 16 of the first slide member 10 and the operation unit 38 of the second slide member 30 are closest to each other by relative sliding, Then, it will be in the state which the 2nd slide member 30 slid to the innermost part in the said slide space formed on a 1st slide member. A position taken by each slide member in the fixing device 1 in the engaged state is referred to as an “engagement position”. As shown in FIG. 4B, when the fixing device 1 is in the engaged state, a pair of engaging claws 22 and 23 on the first slide member 10 side and an engaging claw 43 on the second slide member 30 side are provided. , 42 are the most separated states (the distance between the claws is maximum). As a result, each engaging claw is engaged with the binding tool 60 or the like not shown in FIG. 4B, whereby the binding tool 60 is fixed to the file body 80. Further, the slide protrusion 13 of the first slide member 10 is accommodated in the divided region 32 a of the second slide member 30.

On the other hand, in the disengaged state of the fixing device 1, as shown in FIG. 5A, the operation unit 16 of the first slide member 10 and the operation unit 38 of the second slide member 30 are relatively separated from each other by relative sliding. The positional relationship, in other words, the second slide member 30 protrudes most from the slide space formed on the first slide member. A position taken by each slide member in the fixing device 1 in the disengaged state is referred to as an “engagement disengaged position”. As shown in FIG. 5B, when the fixing device 1 is in the disengaged state, the engaging claws 22 and 23 on the first slide member 10 side and the engaging claws on the second slide member 30 side are paired. 43 and 42 are in the closest state (distance between claws is the smallest). As a result, each engagement claw does not engage with the binding tool 60 or the like not shown in FIG. 4B (each engagement claw moves from the engagement position to the engagement release position, so that the engagement with the file body 80). Therefore, the fixing of the binding tool 60 to the file body 80 is released. Further, the slide protrusion 13 of the first slide member 10 is accommodated in the divided region 32 b of the second slide member 30.

Next, the configuration of the binding tool 60 will be described based on FIGS. 6A to 6C. As described above, the binding tool 60 includes the base member 61, the first binding member 70, and the second binding member 75, and the base member 61 is combined with the first binding member 70 and the second binding member 75. By attaching to the paper, binding of documents and the like is performed. Note that the binding tool 60 is essentially the same quality as a conventional binding tool from the viewpoint of the function of binding a document or the like, and thus the description of the configuration based on this viewpoint is omitted. On the other hand, since the fixing device 1 according to the present invention is for fixing the binding tool 60 to the file body 80, the configuration related to the fixing will be described mainly.

Here, FIG. 6A is a top view of a state in which the first binding member 70 and the second binding member 75 are combined and attached to the base member 61. 6B is a diagram when the state shown in FIG. 6A is viewed from the back side. FIG. 6C is a diagram illustrating the configuration of the first binding member 70 and the second binding member 75.

First, the base member 61 has two side wall portions 61b (see FIG. 1), a binding claw portion 61a provided on each of the side wall portions 61b, and a base plate as a base member that comes into contact with the file body 80. 61c. As shown in FIG. 6C, the first binding member 70 includes a side wall portion 71, a recess portion 72 provided in a central portion of the side wall portion 71, and two pipe pipes extending from the side wall portion 71. 73, the second binding member 75 has a side wall portion 76, a recess portion 77 provided in a central portion of the side wall portion 76, and a foot tube 78 extending from the side wall portion 76. By inserting the foot pipe 78 into the pipe pipe 73, the first binding member 70 and the second binding member 75 are combined, and in the combined state, the first binding is performed on each side wall portion 61 b of the base member 61. Since the side wall portion 71 of the member 70 and the side wall portion 76 of the second binding member 75 are installed, each binding claw portion 61a of the base member 61 is connected to the recess portion 72 of the first binding member 70 and the second binding member. It catches on the hollow part 77 of 75, and reaches the state shown to FIG. 6A. In addition, formation of the binding tool by the combination of the first binding member 70, the second binding member 75, and the base member 61 is based on a conventional technique.

Here, a plurality of types of holes are provided on the base plate 61c of the base member 61. First, a projecting portion 65 extending in the longitudinal direction of the base plate 61c is provided at the central portion of the base plate 61c. The protrusion 65 is formed by raising the base plate 61c from the back surface side to the front surface side. Then, two claw positioning holes 62 are provided on each of the left and right sides of the protruding portion 65 and along the protruding portion 65. The positioning hole 62 with claw has a generally rectangular shape, but positioning claw 63 formed by bending a part of the base plate 61c to the back side is provided on the upper and lower sides shown in FIG. 6A. . As a result, as shown in FIG. 6B, the positioning claw 63 is erected vertically from the back surface of the base plate 61c.

Next, in FIG. 6A, a positioning hole 64 is provided between two positioning holes 62 with claws located on the right side of the protrusion 65. The positioning hole 64 is a substantially rectangular hole penetrating the base plate 61 c, and is formed on the positioning protrusion 21 of the first slide member 10 and the positioning protrusion 41 of the second slide member 30 in the fixing device 1 described above. Correspond.

Further, the base plate 61c has an engagement hole portion 66 formed as a through-hole of the base plate 61c on the both sides of the protrusion 65 on the extension of the protrusion 65 and a positioning hole when engaged. 67 is provided. The engagement hole 66 is a substantially rectangular through hole, and two positioning holes 67 at the time of engagement communicate with the engagement hole 66 in the longitudinal direction of the base plate 61 c across the engagement hole 66. It is provided as follows. The engaging hole 66 and the engaging positioning hole 67 correspond to the positioning pieces of the engaging claws 22, 23, 42, and 43.

Next, the configuration of the file body 80 will be described based on FIG. In the spine portion 80a of the file body 80, four file-side positioning holes 82 are provided in order to position the binding tool 60 at a position where the binding device 60 is to be fixed. The file-side positioning hole 82 is a rectangular through-hole, and is arranged so that two positioning claws 63 included in one positioning hole 62 with a claw on the binding tool 60 side are fitted into one of the through holes. As a result, the binding tool 60 is positioned on the spine portion 80a.

Then, in the state where the binding tool 60 is positioned, the file side which is the through hole is located at the position of the spine portion 80a corresponding to the engagement hole 66 on the binding tool 60 side and the positioning hole 67 when engaged. An engagement hole 86 and a positioning hole 87 for file side engagement are provided. Therefore, the file-side engagement hole 86 is a substantially rectangular through-hole, and two file-side engagement positioning holes 87 are formed in the longitudinal direction of the spine portion 80a across the file-side engagement hole 86. The file side engagement hole 86 is provided so as to communicate with the file side engagement hole 86.

The flow for fixing the binding tool 60 to the file body 80 using the fixing device 1 configured as described above will be described with reference to FIGS. 8A to 8G. FIG. 8A shows a state in which the binding tool 60 is positioned and arranged with respect to the file body 80 as described above. Note that the fixing device 1 according to the present invention fixes the binding tool 60 inside the file main body 80 (the side on which the document to be bound is located), and the fixing operation of the binding tool 60 by the fixing device 1 by the user. Is also performed only from the inside of the file body 80. The state shown in FIG. 8A is described from the outside of the file main body 80 so that the relative relationship among the file main body 80, the binding tool 60, and the fixing device 1 can be easily understood, and the file main body 80 is described in a transparent state. is doing.

In the state shown in FIG. 8A, the positioning claw 63 of the binding tool 60 is fitted in the file side positioning hole 82 of the file body 80. In the drawing, the positioning claw 63 is emphasized for the understanding of those skilled in the art. However, when the positioning claw 63 is fitted in the file-side positioning hole portion 82, the spine covers from the hole portion. It does not protrude to the front side of the part 80a. As can also be seen from the figure, the engaging hole 66 on the binding tool 60 side and the positioning hole 67 when engaged are the file side engaging hole 86 on the file body 80 side and the positioning hole when file side engaged. 87 are overlapped corresponding to each. In FIG. 8A, the positioning hole 64 of the binding tool 60 is shown. However, when the binding tool 60 is positioned with respect to the file main body 80, this positioning is viewed from the outside of the file main body 80. The hole 64 is covered with the spine portion 80a.

Note that the fixing device 1 shown in FIG. 8A is placed in the disengaged state described above, and the pair of adjacent engagement claws 23 and 42 and the pair of adjacent engagements similarly. The claws 22 and 43 are aligned from the inside of the file main body 80 as indicated by a one-dot chain line so as to be inserted into the engagement hole 66 and the file side engagement hole 86 that are overlapped as described above. ing. Therefore, the fixing device 1 is in an inverted state.

The state in which the engagement claws 22, 23, 42, 43 of the fixing device 1 in the disengaged state are inserted into the overlapped engagement hole 66 and the file side engagement hole 86 is in a state where In other words, FIG. 8B shows a state in which the fixing device 1 is operated by the user so that the insertion pieces 22b, 23b, 42b, and 43b constituting the respective engaging claws are inserted into the two holes from the inside of the file main body 80. It is shown as a cross-sectional view. In this state, since the lock members 36 and 37 do not have a predetermined insertion space that extends between the pair of engaging claws, they are erected with respect to the slide members 10 and 30 as shown in the figure. It is in a state. FIG. 8C shows a view of the state shown in FIG. 8B as viewed from the outside of the file body 80. As shown in FIG. 8C, the file-side positioning hole 82 is fitted with the positioning claw 63 of the binding tool 60, and the two file-side engagement holes 86 are paired with the engagement claws. Each of 22, 43 and 23, 42 is just inserted, and the engagement claw and the file main body 80 are not engaged with each other. Therefore, at this time, since the positioning pieces of the engaging claws are not fitted into the file side positioning hole 87, the file side positioning hole 87 is visually recognized from the outside of the file body 80 as shown in FIG. 8C. be able to.

Then, by shifting the fixing device 1 from the disengaged state shown in FIGS. 8A to 8C to the engaged state shown in FIGS. 8D and 8E, the fixing device 1 fixes the binding tool 60 to the file body 80. It will be. FIG. 8D shows a state in which the binding device 60 is fixed to the file main body 80 by engaging the fixing device 1 from the outside of the file main body 80, as in FIG. 8A. In the state shown in FIG. 8D, the first slide member 10 and the second slide member 30 constituting the fixing device 1 perform relative sliding, so that the distance between the claws of the pair of engaging claws is maximized. As a result, the overlapping binding tool 60 and the file main body 80 are sandwiched between the engagement pieces 22a, 23a, 42a, 43a of the respective engagement claws and the slide members 10, 30, and thus each engagement piece. Is engaged with the file body. When the fixing device 1 reaches the engaged state in this way, an insertion space for each lock member is formed between the pair of engaging claws as shown in FIG. 8D.

Further, when the fixing device 1 reaches the engaged state, the positioning pieces 22c, 23c, 42c, and 43c of the respective engaging claws are the regions of the engaging hole portion 66 and the file side engaging hole portion 86 that are in an overlapped state. Therefore, it is inserted into the engagement positioning hole 67 and the file-side engagement positioning hole 87 which are in the same overlapped state. As a representative, the engaging claw 22 is shown in FIG. 9 in which the positioning piece 22c is inserted into the positioning hole 87 when engaged on the file side. Thus, the positioning piece 22c provided on the engaging claw 22 is inserted into the positioning hole 87 at the time of file-side engagement, so that the fixing device 1 overlaps when the fixing device 1 changes from the disengaged state to the engaged state. The fixing device 1 is always guided to a predetermined position with respect to the binding tool 60 and the file main body 80 in the closed state, and the file main body 80 and the engaging claws are engaged at the predetermined position. Can do. Therefore, fixing of the binding tool 60 by the fixing device 1 is performed stably and reliably. Also, with this configuration, the relative position of the fixing device 1 in a direction different from the engagement direction on the file back cover can be made constant. Furthermore, even when a force in a direction different from the engagement direction is applied to the fixing device 1, the contact area in the direction from the locking claw 22 to the binding tool 60 or the file body 80 is large, and thus the file body 80. Can be dispersed. In particular, since the file main body 80 is generally made of paper or the like, it may be damaged by the locking claw 22 when such a force is applied, and depending on the strength of the locking claw 22 or the like. Although the latching claw 22 may be damaged, it can be suitably prevented.

8D shows a sectional view of the fixing device 1, the binding device 60, and the file main body 80 fixed in FIG. 8D, and a state when the fixed state is seen from the outside of the file main body 80 as in FIG. 8C. Is shown in FIG. 8F. In these states, an insertion space into which the corresponding lock members 37 and 36 are inserted is formed between the engaging claws 22 and 43 and the engaging claws 23 and 42, respectively. Therefore, as shown in FIG. 8G, the first slide member 10 and the second slide in the fixing device 1 are inserted into the insertion space by rotating the lock members 37 and 36 around the hinge coupling portion as an axis. The relative slide of the member 30 is limited. Thereby, the state in which each engagement claw is engaged with the file main body 80 is maintained.

Here, based on FIG. 10A to FIG. 10C, the state of restriction of the relative slide by the lock member 36 will be described as a representative. FIG. 10A shows an enlarged view of the vicinity of the operation unit 38 on the second slide member 30 side in the fixing device 1 in the engaged state. An inclined portion 14d that is inclined toward the penetrating region 15c is provided along the horizontal frame 14c of the first frame member 10. The lock member 36 hinged to the second slide member 30 is provided with an inclined portion 36e formed so that the first plate portion 36a is chamfered along the edge of the first plate portion 36a. .

Therefore, in the fixing device 1 in the engaged state, the lock member 36 is rotationally moved so that the lock member 36 is inserted into a predetermined insertion space. Then, as shown in FIG. 10B which is a cross-sectional view of the state shown in FIG. 10A, the inclined portion 14d on the first slide member 10 side and the inclined portion 36e on the lock member 36 side come into contact with each other. The inclined surfaces of the two inclined portions are formed so that the lock member 36 is easily guided to the insertion space. Therefore, after the contact, the user applies a slight force to the lock member 36 to prompt the two inclined portions. However, elastic deformation occurs between the first slide member 10 and the second slide member 30, and as a result, the lock member 36 is smoothly accommodated in the insertion space (the state shown in FIG. 10C). In the state shown in FIG. 10C, the contact portion 36 c of the lock member 36 is in contact with the insertion piece 23 b of the engagement claw 23 on the first slide member 10 side, and the second plate portion 36 b of the lock member 36. The tip end portion (the portion not connected to the first plate portion 36a and the opposite end portion of the first plate portion 36a) is in contact with the insertion piece 42b of the engaging claw 42 on the second slide member 30 side. It has become. That is, when the lock member 36 is fitted between the engagement claw 23 and the engagement claw 42, the relative movement of both the engagement claws, that is, the relative relationship between the first slide member 10 and the second slide member 30. Limit slides. As for the lock member 37, as in the case of the lock member 36, the relative movement of the engagement claw 22 and the engagement claw 43 can be restricted.

Here, the shape of each engaging claw in the fixing device 1 will be described based on FIG. In FIG. 11, the engaging claws 23 and the engaging claws 42 are representatively illustrated, but the same technical idea is applied to the engaging claws 22 and 43. When each engaging claw is engaged with the binding tool 60 and the file main body 80 as shown in FIGS. 8D to 8F, each engaging piece comes into contact with the file main body 80 and the like, and each engagement piece is in contact with each slide member. Inclined portions 23a1 and 42a1 are provided at the distal end portions of the engaging pieces 23a and 42a of the engaging claws 23 and 42 that make a pair so that the file main body 80 and the like are smoothly sandwiched. This facilitates relative sliding of the first slide member 10 and the second slide member 30 in order to shift from the state shown in FIGS. 8B and 8C to FIGS. 8D to 8F.

In the fixing device 1 configured as described above, a pair of engaging claws 23 inserted into the overlapping engaging hole 66 of the binding tool 60 and the file side engaging hole 86 of the file main body 80 are paired. , 42 are in opposite directions to each other. In the present embodiment, when the file main body 80 is used as a reference, the engagement directions of the engaging claws 23 and 42 are opposite to each other in the vertical direction of the file main body 80. The same applies to the engaging claws 22 and 43 that make a pair.

In this way, the engagement directions of the engagement claws inserted into the overlapped one engagement hole 66 and file side engagement hole 86 are different from each other, and preferably opposite to each other. When an external force is applied to the fixed portion of the binding tool 60 due to dropping or the like, the engagement state of the binding tool 60 by the fixing device 1 can be satisfactorily maintained regardless of the direction of the external force. In the fixing device that can be attached to and detached from the file main body 80 only from one side, the engaging claw is deformed by a slight impact or the weight of the bound document etc. If this configuration is adopted, one engagement claw inserted into one file-side engagement hole will be used. Even if the above action works, the other engaging claw has the opposite action (tightening action / enhancing engagement action), so the "engagement force of the fixing device with respect to one file side engagement hole" is This is because it works well in any case. Therefore, the engagement directions of the engagement claws are preferably opposite to each other so that even if a force in the engagement release direction is applied to one, a force in the engagement strengthening direction is applied to the other. By engaging the file body 80 in opposite directions in the vertical direction of the file main body 80 as in the present embodiment, one engagement claw is used when the file is dropped during practical use, especially when leaning on a library or the like. The force in the disengagement direction is easily applied to the fixing device, and the conventionally proposed "technology that enables access to the file body of the binding tool by access from only one side" causes the fixing device to fall out, thus not putting it to practical use. Since the problem of the cause can be solved and the degree of freedom in designing the size and shape of the engaging claws can be further increased, the fixing of the binding tool 60 to the file body 80 can be made more reliable. it can.

Next, functions of the positioning protrusions 21 and 41 in the fixing device 1 according to the present invention will be described based on FIGS. 12A to 12C. FIG. 12A shows a state in which the relative relationship between the fixing device 1 and the binding tool 60 in the disengaged state is viewed from the outside of the file main body 80. 12C shows a state when the relative relationship between the fixing device 1 in the engaged state and the binding tool 60 is viewed from the outside of the file main body 80. Further, FIG. 12B is shown in FIGS. The intermediate state of the state shown, ie, the state where the positions of the first slide member 10 and the second slide member 30 in the fixing device 1 are intermediate positions between the engagement position and the engagement release position is shown. 12A to 12C, the file main body 80 is described in a transparent state by a two-dot chain line.

Here, when the fixing device 1 is in the disengaged state, as shown in FIG. 12A, the positioning projection 21 is positioned with respect to the positioning projections 21 and 41 accommodated in the positioning hole 64 of the binding tool 60. The first slide member 10 and the second slide member 10 forming the disengaged state are in contact with the upper side 64 a of the hole 64 and the positioning protrusion 41 is in contact with the lower side 64 b of the positioning hole 64. The relative position of the slide member 30 with respect to the binding tool 60 is uniquely determined. At this time, the pair of engaging claws 22 and 43 and the engaging claws 23 and 42 are not in contact with the corresponding engaging hole portions 66 and the like.

As described above, when the fixing device 1 is released from the engagement state due to the correlation between the positioning projections 21 and 41 on the fixing device 1 side and the positioning hole 64 on the binding tool 60 side, The relative positional relationship between the fixing device 1 and the binding tool 60 is uniquely determined so as to be in a non-contact state with respect to the engaging hole 66 to be performed. As a result, when the user operates the first slide member 10 and the second slide member 30 to bring the fixing device 1 into the disengaged state, each engagement claw is inevitably non-engaged with respect to the engagement hole 66 and the like. Since the contact state is established, the fixing device 1 can be easily extracted from the binding tool 60. This greatly contributes to the improvement of the user's workability when removing the binding tool 60 from the file body 80.

When the fixing device 1 in the disengaged state is shifted to the engaged state, the positioning protrusions 21 and 41 contact any side 64a or 64b of the positioning hole 64 as shown in FIG. 12B. The state shown in FIG. At this time, the positioning projection 21 is in contact with the lower side 64 b of the positioning hole 64, and the positioning projection 41 is in contact with the upper side 64 a of the positioning hole 64. As a result, as in the case of the disengaged state, the relative positional relationship between the fixing device 1 and the binding tool 60 is uniquely determined even in the engaged state.

Next, functions of the slide protrusion 13 and the slide groove 32 in the fixing device 1 according to the present invention will be described based on FIGS. 13A and 13B. FIG. 13A shows the relationship between the state of each engaging claw and the slide protrusion 13 and the slide groove 32 in the fixing device 1 in the engaged state, and FIG. 13B shows the relationship in the fixing device 1 in the disengaged state. The relationship between the state of each engaging claw and the slide protrusion 13 and the slide groove 32 is shown. 13A and 13B, the left side is a top view of the fixing device 1, and the right side is a sectional view thereof.

As described above, when the relative slide is performed by the user's operation between the engagement position and the engagement release position in the fixing device 1, the slide protrusion 13 provided on the first slide member 10 is The vehicle moves back and forth between the divided areas 32a and 32b in the slide groove 32 while getting over 33. Here, as shown to FIG. 13A, the division area 32a has a shape which accommodates the slide projection part 13 almost without gap. Thereby, when the fixing device 1 is in the engaged state, even if the relative slide is not restricted by the lock members 36 and 37, the slide protrusion 13 is moved by the protrusion 33 in the slide groove 32. Therefore, the relative positional relationship between the first slide member 10 and the second slide member is maintained unless an external force is applied to the slide protrusion 13 over the protrusion 33. Therefore, even if the lock members 36 and 37 are not sufficiently inserted into the insertion space, the fixing of the binding tool 60 to the file body 80 is maintained to some extent.

On the other hand, as shown in FIG. 13B, the shape of the divided region 32b is a shape having an extra gap so that when the slide protrusion 13 is accommodated, the slide protrusion 13 can still slide to some extent. That is, the divided area 32b is wider than the divided area 32a, and the slide protrusion 13 can slide to some extent within a limited range within the divided area 32b. As a result, in a state where the binding tool 60 is about to be fixed to the file body 80 from now on (for example, the state shown in FIG. 8A), the user who is going to operate the fixing device 1 is the first slide member 10 and the second slide member. 30 can be recognized by the tactile sensation that it can slide within the limited range, so that it can be recognized that the fixing device 1 is in the disengaged state, and the user's subsequent work can be smoothly performed. Can be done. In other words, when the binding tool 60 is to be fixed to the file main body 80 from now on, the user may feel the sliding within the limited range of the first slide member 10 and the second slide member 30 by tactile sensation. When the fixing device 1 cannot be engaged, the fixing device 1 is in the engaged state, not in the disengaged state, so that it can be smoothly shifted to the fixing operation of the binding tool 60 immediately after being changed to the disengaged state.

Further, unlike the above-described embodiment, the shape of the divided region 32b may be a shape that accommodates the slide protrusion 13 with almost no gap, like the divided region 32a. In this case, even when the fixing device 1 is in the disengaged state, the slide protrusion 13 is restricted from moving in the slide groove 32 by the protrusion 33, so the slide protrusion 13 gets over the protrusion 33. As long as an external force does not act, the relative positional relationship between the first slide member 10 and the second slide member is maintained. Therefore, when the fixing device 1 is to be inserted / removed into / from the overlapped engagement hole 66 or the like, each engagement claw does not move, so that each engagement claw is displaced from the engagement position or the like. Thus, it can be prevented that the attachment / detachment work is hindered by being caught by the binding tool, so that it can be said that the workability of the user is improved.

Next, the function of the protrusion 65 will be described with reference to FIG. FIG. 14 is a diagram illustrating a state in which the fixing device 1 and the binding tool 60 in the engaged state are viewed from the outside of the file main body 80 in a state of being attached to the file main body 80, with the projecting portion 65 as a center. In this case, the base plate 61c around the protrusion 65 is shown in a cut state so that the state of the back side of the fixing device 1 can be easily grasped.

It should be noted here that the slide recess 24 provided in the first slide member 10 and the slide recess 46 provided in the second slide member 30 with respect to the protruding portion 65 of the binding tool 60 (see, for example, FIG. 3B). ). Specifically, when the binding device 60 is fixed by the fixing device 1, the relative positions of the fixing device 1 and the binding device 60 are such that both the slide concave portions cover the protruding portions 65. The positional relationship is determined. That is, as described above, both the slides even when the positioning projections 21 and 41 are inserted into the positioning holes 64 and when the fixing device 1 is placed in the engaged state as shown in FIG. The concave shape of the recess covers the protruding portion 65.

Therefore, when the first slide member 10 and the second slide member 30 are relatively slid, the slide recess of each slide member extends over the protrusion 65 of the binding tool 60. It will slide in the present direction. In other words, when the user operates the first slide member 10 and the second slide member 30 to perform relative sliding, the protruding portion 65 functions as a guide for the relative sliding. For this reason, the user can smoothly move both slide members to the engaged position or the disengaged position, thereby improving the workability of the user.

Here, as shown in FIG. 3A, the second slide member 30 performs the relative sliding in a state where it is substantially disposed above the first slide member 30. However, when the second slide member 30 is positioned on the upper side, there is a possibility that an operation of holding the operation units 16 and 18 and lifting each slide member may be performed depending on the user to be used. Of course, the two sliding members cannot slide relative to each other by this lifting operation, but if the user's force is too large, the fixing device 1 may be damaged by this lifting operation. When the fixing device 1 is in the disengaged state, the engaging claws are not engaged with the file body 80 or the like, so that even if the user performs a lifting operation, the fixing device 1 does not engage with the engaging hole. The possibility of damaging the fixing device 1 is low only by being pulled out from the portion 66 or the like.

However, when the fixing device 1 is in the engaged state, each engaging claw is engaged with the file main body 80. Therefore, if the user performs a lifting operation, the first slide member 10 and the second slide member 30 are engaged. There is a high possibility that the fixing device 1 will be damaged due to the combination with. Therefore, in the fixing device 1 according to the present invention, when it is in the engaged state, the first slide member 10 and the second slide member 30 are temporarily placed in the adjacent portion of the operation unit 38 where the user performs an operation. In contrast, when the lifting operation is performed, the two members interfere with each other by the planar protrusion 40 of the second slide member 30 and the end 12a of the upper vertical frame 12 of the first slide member 10. Details of this state are shown in FIG.

As can be clearly seen from FIG. 15, in the fixing device 1 in the engaged state, the second slide member 30 is positioned above the first slide member 10. The planar protruding portion 40 provided adjacent to the portion 38 is in a state of being buried under the end portion 12a of the upper vertical frame 12 on the first slide member 10 side. Therefore, even if the user mistakenly lifts the fixing device 1 via the operation unit 38 in the state shown in FIG. 15, the planar protrusion 40 is immediately caught by the end 12 a and Can give a sense of incongruity. As a result, it is possible to avoid the operation unit 38 being inadvertently lifted upward due to an erroneous operation by the user.

<Modification>
The disclosure of the embodiment of the fixing device according to the present invention is not limited to the above-described embodiment. That is, as long as the direction of engagement of the file main body by the engagement of the engagement claws inserted into one engagement hole 66 or the like is at least two different directions, the fixing device according to the present invention. This is an example. Therefore, for example, the number of engagement claws inserted into one engagement hole 66 or the like may be three or more. Further, if the number of engaging claws inserted into one engaging hole 66 or the like is two or more, the number of engaging claws inserted into the other engaging hole or the like is one. Good.

In the above description, it is assumed that the number of the engagement holes 66 provided in the binding tool 60 and the file main body 80 is two, but the number is naturally not limited to two. Even in the case of one or three or more cases, it is included in the category of the fixing device 1 according to the present invention.

Further, the configuration that restricts the movement of the two slide members that perform relative sliding, such as the lock members 36 and 37, is not necessarily a configuration that is necessary as the fixing device according to the present invention. At least when the slide member reaches the engagement position, the engagement state with the file main body 80 may be maintained and the binding tool 60 may be fixed to the file main body 80. Of course, even when the lock member is provided, the number is not limited to two, and may be one or three as long as it is an appropriate number that can limit the movement of the slide member for relative sliding. That's all.

Furthermore, the technical idea about the positioning of the fixing device 1 by the positioning projections 21 and 41 and the positioning hole 64, and the technical idea about the maintenance of the engagement state of the slide members 10 and 30 by the slide projection 13 and the slide groove 32. As for the technical idea regarding the relative slide guide by the slide recesses 24 and 46 and the projecting part 65, and the technical idea regarding the catch between the flat protrusion 40 and the end 12 of the upper vertical frame 12, the applicant has carried out the above-mentioned implementation. The examples are disclosed all together, but these may be combined as appropriate, and any combination thereof is also included in the scope of the applicant's disclosure. In addition, each of the above-described technical elements and the following technical elements are inventions, and each of them has a sufficient effect even if it is used alone. Needless to say, it is effective.

Furthermore, on the upper surface of the base portion 131, the slide groove portion 132 is formed by cutting out two side edges extending in the longitudinal direction along the longitudinal direction. The slide groove 132 is functionally the same as the slide groove 32 in the first embodiment. A projection 133 is provided at the center of the slide groove 132 so as to divide the area in the slide groove 132 into two divided areas 132a and 132b.

Next, the configuration on the back side of the second slide member 130 will be described. In the base part 131, an annular frame part 131c is provided on the back side so as to include a place where the above-described slide groove part 132 is provided on the front side. Since the thickness of the base portion 131 in which the frame portion 131c is disposed is increased, the strength of the base portion 131 is reduced by the amount notched to form the slide groove portion 132.

A columnar positioning protrusion 141 protruding to the back side of the fixing device 100 is provided on the lower surface of the side in the longitudinal direction of the second slide member 130 among the sides forming the frame portion 131c. This is functionally the same as the positioning protrusion 41 in the first embodiment.

Further, among the sides forming the frame portion 131c, the side in the width direction (direction perpendicular to the longitudinal direction) of the second slide member 130 is functionally the same as the slide recess 46 in the first embodiment, and the lower surface is arcuate. Two recessed recesses 146 are formed along the longitudinal direction of the second slide member 130. Further, on the back side of the second slide member 130, the engagement claws 142 and 143 functionally identical to the engagement claws 42 and 43 in the first embodiment project in the vicinity of the slide projections 144 and 145, respectively. Two each are provided. Further, the central axis of the one engaging claw 142 and the one engaging claw 143 along the longitudinal direction of the second slide member 130 and the central axis along the extending direction of the one slide recess 146 coincide with each other, and the other In the engaging claws 142, the engaging claws 143, and the slide concave portions 146, the respective components are arranged on the corresponding horizontal frames so that the respective central axes coincide with each other.

The first slide member 110 and the second slide member 130 configured as described above are made of resin as in the case of the first slide member 10 and the second slide member of Example 1, and elastic deformation of the resin is performed. By using the first slide member 110 and the second slide member 130 in combination, the fixing device 100 according to the present invention is formed.

In the fixing device 100 in which the first slide member 110 and the second slide member 130 are combined in this way, the second slide member 130 is positioned on the horizontal frames 114a to 114c of the first slide member 110 (FIG. 18B). Relative to the first slide member 110 in a slide space extending in the longitudinal direction of the first slide member 110, which is generally formed by the horizontal frames 114a to 114c and the upper vertical frame 112. Can be slid (relative sliding) (see FIG. 18A). At this time, as shown in FIGS. 18A and 18B, the second slide member 130 is sandwiched in the vertical direction by the horizontal frames 114a to 114c of the first slide member 110 and the slide protrusion 113, so that the slide Relative sliding in the space can be performed smoothly. Further, as shown in FIG. 18B, the second slide member 130 has the slide protrusions 144 and 145 guided in the slide direction by the step portions 119 and 120 of the first slide member 110, and thus the second slide member 130. A smooth relative slide can be secured while suppressing separation of the member 130 and the first slide member 110.

Here, the engagement claws 122 and 123 provided on the first slide member 110 and the engagement claws 142 and 143 provided on the second slide member 130 have the same shape, and the engagement in the first embodiment. The same applies to the nail 22 and the like. Therefore, description of the detailed structure of each engaging claw is omitted. The engagement directions of the engagement claws 122 and 123 of the first slide member 110 are the same, and the engagement directions of the engagement claws 142 and 143 of the second slide member 130 are the same. The engaging direction of 123 is opposite to the engaging direction of the engaging claws 142 and 143. Then, in the fixing device 100, as shown in FIG. 18B, a pair of engaging claws are formed in a state where the engaging claws 123 and the engaging claws 142 are opposite to each other. A pair of engaging claws are formed in a state where the engaging directions of the claws 122 and the engaging claws 143 are reversed.

Here, in each pair of engagement claws, the distance between the one engagement claw and the other engagement claw varies with relative sliding of the first slide member 110 and the second slide member 130. . In the state where the distance between the claws of the engaging claws is widest, the lock members 136 and 137 provided on the second slide member 130 side are rotationally displaced, so that the insertion space formed between the engaging claws. As a result, the relative sliding of the first slide member 110 and the second slide member 130 is restricted, and the engagement state of the fixing device 100 is maintained. Further, when it is desired to perform relative sliding again, the lock members 136 and 137 are rotated and displaced in the direction opposite to the previous direction so that the lock members are removed from the space formed between the engaging claws. .

Here, a detailed configuration of the lock members 136 and 137 will be described based on FIGS. 17B and 18A. Since the lock members 136 and 137 have the same configuration, only the lock member 136 will be described as a representative. The lock member 136 is a plate-like operation plate portion 136d that is hinged to the base portion 131 of the second slide member 130, and a plate-like member that stands vertically with respect to the operation plate portion 136d. The plate-like plane is a first plate portion 136a extending in the width direction of the base portion 31, and a plate-like member standing upright to the operation plate portion 136d, with respect to the first plate portion 136a. Even on the two planes 136b that are parallel to each other and the plate-like plane of the first plate part 136a, on the plane opposite to the connection point with the second plate part 136b, the operation plate It has two contact parts 136c of a semi-cylindrical shape provided so as to be perpendicular to the part 136d.

Here, in the fixing device 100, similarly to the fixing device 1 shown in the first embodiment, the pair of the above-described pair of slide members 110 and the second slide member 130 is moved depending on the relative positions of the first slide member 110 and the second slide member 130. The state of the engagement claw changes, and as a result, the engagement state of the binding tool 160 or the like via each engagement claw changes, whereby the binding tool 160 is fixed or removed.

Let Then, using the operation unit 316, the first slide member 310 is slid in the direction in which the spring 346 is contracted. In FIG. 32A, after the operation unit 316 is rotated until it is substantially perpendicular to the base portion 311 of the first slide member 310, the first slide member 310 is engaged with the hooking projection of the second slide member 330. The state pulled to the vicinity of 334 is shown.

In this disengaged state, as shown in FIG. 32B, the distance between the claws of the engaging claws 323 and 343 and the engaging claws 328 and 342 that are paired is minimized. These engaging claws can be extracted. In order to bring the fixing device 300 from the disengaged state to the engaged state, if the tensile force applied to the operation unit 316 is removed, the fixing device 300 reaches the engaged state by the biasing force of the spring 346.

Next, the configuration on the back side of the slide member 410 will be described. Two engaging claws 421 corresponding to the engaging claws 22 and the like in the first embodiment are arranged on the back side of the horizontal frame 412, and the back side of the horizontal frame 415 similarly corresponds to the engaging claws 22 and the like. Two engaging claws 420 are arranged. These engagement claws 420 and 421 all have the same shape, and the engagement direction of the file body by the engagement claws is also the same direction (direction from the horizontal frame 412 to the horizontal frame 415).

A groove 419 extending in the extending direction of the vertical frame 411 is provided on one side of the L-shape of the horizontal frame 414 (side parallel to the vertical frame 411), and the groove 419 is opposed to the horizontal frame 415. And extends to the vicinity of the other side of the horizontal frame 414. As will be described later, when the fixing device 400 is formed by combining two slide members 410, the vertical frame 413 of one slide member 410 is inserted into the groove portion 419.

By using two slide members 410 configured in this manner, the horizontal frames 418 (418 ′) face each other, and the fixing device 400 is combined to be a rolling target, thereby fixing according to the present embodiment. A device 400 is formed. The specific configuration of the fixing device 400 is shown in FIG. 34A and the like. However, in describing the configuration, when describing the configuration related to one slide member 410, no dash is attached to the reference number, and the other slide is shown.

In the fixing device 400, the vertical frame 416 of one slide member 410 rides on the horizontal frame 412 'of the other slide member 410', and the operation unit 417 rides on the horizontal frame 415 '. Similarly, the vertical frame 416 'rides on the horizontal frame 412, and the operation unit 417' rides on the horizontal frame 415.

Further, the vertical frame 413 of one slide member 410 is inserted into the groove 419 ′ of the other slide member 410 ′, and similarly, the vertical frame 413 ′ of the other slide member 410 ′ is inserted into the groove 419 of the one slide member 410. It will be inserted. Then, a spring 430 for applying an urging force is attached between the two slide members 410 and 410 ′ via attachment portions 418 and 418 ′ provided on the opposing horizontal frames 418 and 418 ′. In the fixing device 400 formed in this way, both slide members perform relative sliding similar to that in the first embodiment, and both the slide members reach the engagement position or the disengagement position. A combined state or a disengaged state will be formed.

As a result, the distance between the claws of the engaging claws 420 and 421 ′ that make a pair becomes the maximum. At this time, as shown in FIG. 34B, the spring 430 has returned to its natural length from the compressed state, and the vertical frame 413 (413 ′) of each slide member corresponds to the groove 419 ′ (419). ). Therefore, the relative positional relationship between the slide members is maintained to some extent by the urging force from the spring 430.

Also, in order to bring the fixing device 400 from the engaged state to the disengaged state, both the slide members are slid in the direction in which the spring 430 is contracted. Specifically, the user may perform an operation so as to pick the horizontal frames 414 and 414 'with his / her finger.
