FIG. 6 is a plan view showing the engagement relationship between the engagement member and the engaged portion as the lever moves. In the following description, when the word "front" is used, the right side of the paper in FIG.
The term "rear" refers to the left side of the drawing, the term "one side" refers to the right side of FIG. 3, and the term "other" refers to the left side of the figure.

A bottom plate 5 is rotatably provided via a hinge pin 7 on one side of an attachment member 6 attached to the binding body 2 (see FIG. 9) by fastening means such as a rivet 3. That is, the insertion portions 5e, 5e of the hinge pin 7 are formed on one side of the bottom plate 5 and the attachment member 6, and the hinge pin 7 is inserted through the insertion portions 6b, 6b to rotatably connect the bottom plate 5 and the attachment member 6. It Reference numeral 9a is a coil spring (hereinafter referred to as a spring) wound around the hinge pin 7 and serving as a first biasing means, and always biases the bottom plate 5 in the direction of rotating to the other side. Reference numeral 9c is a coil spring (hereinafter referred to as a spring, but may be a leaf spring) as a second biasing means that is wound around the hinge pin 8 and always biases the side plate 4 in the counterclockwise direction.

On the other side of the bottom plate 5, a side plate 4 is rotatably provided via a hinge pin 8. Bottom plate 5 and side plate 4
Also, similar to the above, the insertion portions 5f, 4 formed in the respective
They are connected by a hinge pin 8 which is inserted through d. On one side of the side plate 4, a pin body 10a is attached as a quarter arc insertion member having a center of curvature of the side plate 4 toward the bottom plate 5, that is, a hinge pin 8 as a center of curvature.
On the other hand, on the upper surface of the bottom plate 5, a quarter-arc binding tube 10b having the same radius of curvature as the pin body 10a and allowing the pin body 10a to be inserted and removed is attached. The pin body 10a is inserted into the binding tube 10b, and the side plate 4 having the hinge pin 8 as an axis.
With the rotation of, it moves back and forth in an arc with respect to the binding tube 10b. The pin body 10a and the binding tube 10b described above constitute a binding member 10 that binds a document to the binding body 2 by inserting a punch hole formed in the document. In this embodiment, since the tip of the quarter-arc-shaped binding tube 10b abuts on one side of the side plate 4 which is vertically raised with respect to the bottom plate 5, the side tube 4 is formed by the binding tube 10b. Rotation to one side is restricted. That is, in this embodiment, the binding tube 10b constitutes the regulation means.

However, if the side plate 4 can be restrained from rotating to one side, the regulating means is the binding tube 1 described above.
The side plate 4 is not limited to 0b, and for example, a protrusion is provided on either the side plate 4 or the bottom plate 5, and the protrusion is brought into contact with the bottom plate 5 or the side plate 4 so that the side plate 4 has a predetermined angle to one side with respect to the bottom plate 5. It is also possible not to rotate more than 90 degrees in this embodiment. Further, the binding member 10 in this embodiment is effective when the number of holes such as 2 holes and 4 holes is relatively small, but when the number of holes of a document is large (6 holes, 26 holes, etc.). In consideration of the manufacturing cost, for example, a quarter arc pin body is provided with the side plate 4 depending on the hole position.
And the bottom plate 5 may be alternately arranged.

On the lower surface of the bottom plate 5, one plate-shaped lever 11 is attached as an advancing / retreating member that can move back and forth in the longitudinal direction of the bottom plate 5. An insertion portion 11f for the hinge pin 8 is formed on the other side of the lever 11,
The hinge pin 8 between the insertion portion 11f of No. 1 and the insertion portion 4d of the side plate 4 or the insertion portion 5f on the other side of the bottom plate 5 serves as a biasing means for constantly biasing the lever 11 as an advancing / retreating member in the backward direction. The compression coil spring 9b is wound. The coil spring 9b constantly urges the lever 11 to the rear side to allow the lever 11 to automatically return, and restricts the forward movement of the lever 11 when a document is bound, For example, when the binding body 2 is dropped from the shelf, even if a large impact is applied to the binder metal fitting 1, the binder metal fitting 1 is not easily opened. In addition, at the front end of the lever 11, a hook portion 11a is formed by bending the front end portion of the lever 11 upward at a substantially right angle so that a user can easily catch his / her finger, and a hook 11a is formed at an intermediate portion of the lever 11. The convex portion 11b is formed so as to project toward one side, and is engaged with the guide portion 5a of the bottom plate 5. The lever 11 can move forward and backward with respect to the bottom plate 5 by the convex portion 11b engaging with the guide portion 5a and sliding while being guided along the guide portion 5a.

On the other side of the lever 11, one or a plurality of parts that extend outward from the bottom plate 5 to the other side and rise substantially vertically along the other side surface of the side plate 4 that is vertically installed on the bottom plate 5. (Two in this embodiment) support members 11
c and 11c are provided. This support member 11c, 1
1c supports the side plate 4 from the other side and holds the side plate 4 in a state of standing upright with respect to the bottom plate 5. It should be noted that when a large number of documents are bound to the binding member 10, a large addition may be applied to the side plate 4 toward the other side, so the support members 11c and 11c should not be easily deformed. For this reason, in this embodiment, the support member 11c and the lever 11 are subjected to a tuftride process to improve the hardness. Of course, if sufficient hardness can be obtained by other heat treatments or surface treatments than the tuftride treatment, the other heat treatments or surface treatments described above may be used, and the lever 11
Alternatively, the support members 11c and 11c may be made of a metal material having high hardness.

Further, as shown in FIG. 2, in this embodiment, the front and rear length of the side plate 4 is formed to be shorter than the front and rear length of the bottom plate 5, and the gap between the hook portion 11a and the front end portion of the side plate 4 is set. There is a gap in it. Therefore, the user can insert his / her finger into the gap from the side plate 4 side and easily hook the hook on the hooking portion 11a, which facilitates the work. Below the side plate 4, the support member 11 is provided.
The recesses 4a and 4a into which the c and 11c can be respectively inserted are formed, and the support member 11 is formed as the lever 11 advances.
When c and 11c move to the recesses 4a and 4a, the support of the side plate 4 by the support members 11c and 11c can be released. Further, stoppers 4b for restricting the support members 11c, 11c from advancing beyond the recesses 4a, 4a are formed in the recesses 4a, 4a so as to project toward the front side of the hole periphery. Further, cutout portions 4c, 4c as guide portions of the support member are formed in front of the recesses 4a, 4a in parallel with the forward and backward movement direction of the lever 11, respectively.

According to the above mode, when the lever 11 is pulled forward (in the direction of the arrow in FIG. 2) against the biasing force of the coil spring 9b, the support members 11c and 11c are stopped by the stopper 4b.
Move forward until it touches. The lever 11 is a support member 11
When c and 11c come into contact with the stopper 4b, the first movement (first stage advancement) is restricted. At this time, since the support members 11c and 11c are located in the recesses 4a and 4a, respectively, the support of the side plate 4 by the support members 11c and 11c is released and the side plate 4 is rotated to the other side by the biasing force of the spring 9c. Move (the direction of rotation is indicated by arrow A in FIG. 4). The support members 11c, 11c are inserted into the recesses 4a, 4a and are located below the recesses 4a, 4a. In this state, since the support members 11c, 11c are located near the entrances of the cutouts 4c, 4c, by pulling the lever 11 further forward, the support members 11c, 11c are cutouts 4c, 4c.
4c can be advanced and advanced (the second stage of advancement). In this embodiment, with this structure, the single lever 11 can be advanced stepwise.

On the bottom plate 5, an engaging member 12 having an engaging groove 12a is provided upright in a direction parallel to the moving direction of the lever 11. Then, when the bottom plate 5 is superposed on the mounting member 6, the hole 5b and the hole 1 through which the engaging member 12 can be inserted.
1d is formed on the bottom plate 5 and the lever 11. Further, the lever 11 can be engaged with the engaging member 12 by inserting the engaged portion 11e formed on the front side of the hole peripheral edge of the hole 11d into the engaging groove 12a.
When the lever 11 engages with the engagement member 12, the bottom plate 5 is fixed to the attachment member 6 in a state where the bottom plate 5 overlaps with the attachment member 6. The engagement groove 12a and the engaged portion 11e are engaged with each other with a dimension longer than the forward distance of the lever 11 in the first stage, and as shown in FIG. The state of engagement is maintained by the first step forward movement from the state of FIG. 6A) (the state of FIG. 6B), but the engagement is released by the second step forward movement of the lever 11. (The state of FIG. 6C).

In the above description, the forward / backward moving member is explained as the single lever 11 provided on the bottom plate 5, but two forward / backward moving members are provided and one forward / backward moving member (the second forward / backward moving member) is provided. Means) to form a support member 11c,
The hole 11d may be formed in the other forward / backward moving member (second forward / backward moving means). In this case, each of the advancing / retreating moving members functions separately, and the expansion and the opening of the binder metal fitting 1 are separately contracted. Further, in the above description, the hole 11d is formed in the lever 11 and the engaging member 12 is formed in the mounting member 6, but the lever 11 is formed.
The engaging member may be formed on the mounting member 6, and the mounting member 6 may be formed with a hole or an engaged portion capable of engaging with the engaging member. Further, the spring 9 as the above-mentioned first and second biasing means.
Since a and 9c are for automatically rotating the bottom plate 5 and the side plate 4 by releasing the engagement, releasing the support, releasing the pulling of the lever, and the like, when these operations are forcibly performed manually, It does not matter if it is not provided. Also, the spring 9
b is to allow the lever 11 to automatically move backward, and to prevent the lever 11 from moving forward even when a large impact is applied to prevent the binder fitting 1 from opening. If such a risk is small depending on the mode of use, the storage location, etc., it may be omitted.

Next, the operation of the binder fitting 1 having the above structure will be described. The binder 1 can be assembled by inserting the hinge pin 7 as shown by the dotted line in FIG. 1 and inserting the hinge pin 8 in the direction shown by the dashed line in FIG. Binder fitting 1 assembled in this way
Is attached to the cover 2b of the binding body 2. At this time,
As shown in FIG. 3, when the side plate 4 is rotated to the other side, the hinge pins 8 of the cover sheet 2b and the back plate 2a are arranged so that the rotation of the side plate 4 contacts the back plate 2a and the rotation is restricted. It is attached so as to be located in the vicinity of the fold line portion 2c. As described above, since the lever 11 provided so as to be movable back and forth between the bottom plate 5 and the mounting member 6 is plate-shaped, the thickness of the state where the bottom plate 5 is superposed on the mounting member 6 is made as thin as possible. Therefore, it is possible to reduce a wasteful space between the document and the cover 2b even when the document is bound. The document is bound to the binding body 2 by inserting the binding member 10 into the punch hole.

First, by rotating the side plate 4 to the other side,
The procedure for setting the document to a spread state that allows double-page spread will be described. When a finger is inserted into the gap between the side plate 4 and the hook portion 11a, the finger is hooked on the hook portion 11a and the lever 11 is pulled toward the front side, the lever 11 moves to the support member 11c,
11c moves until it contacts the stopper 4b, and the support members 11c, 11c are located in the recesses 4a, 4a. As a result, the side plate 4 rotates to the other side until it comes into contact with the back plate 2a (the direction of rotation is indicated by arrow A in FIG. 4). By the pulling operation of the lever 11, the fixed state between the mounting member 6 and the bottom plate 5 is maintained, and the pin body 10a is fixed to the binding tube 1.
Since it does not slip out from 0b, the continuity of the binding member 10 is maintained from the bottom plate 5 side to the side plate 4, and the document can be opened without separating from the binding member 10. Next, a procedure for rotating the bottom plate 5 with respect to the mounting member 6 to remove the pin body 10a from the binding tube 10b and to put the binder metal fitting 1 in the open state in which the document shown in FIG. 5 can be replaced is explained. .

Since the support members 11c, 11c are located in the vicinity of the entrances of the cutouts 4c, 4c of the side plate 4 in the opened state where they can be opened, the support members 11c, 11c can be removed by pulling the lever 11 further toward the front side. Notches 4c, 4c
The engaging groove 1 of the engaged portion 11e and the engaging member 12
The engagement with 2a is released. As a result, the fixing of the bottom plate 5 to the mounting member 6 is released, so that the bottom plate 5 is rotated about the hinge pin 7 in the direction indicated by the arrow D in FIG. 5 by the urging force of the spring 9a. By the rotation operation of the bottom plate 5,
Since the side plate 4 rotates in opposite directions with respect to the bottom plate 5 as indicated by arrow C in FIG. 5, the pin body 10a and the binding tube 10b move in the directions indicated by arrow B, and the pin body 10a is bound by the binding tube. The document can be replaced by exiting 10b.

To return the binder fitting 1 from the open state to the initial binding state, the following procedure is performed. With the lever 11 pulled toward you, the bottom plate 5 is pushed by hand to rotate to the mounting member 6 side, that is, to the side opposite to the arrow D, and the engaging member 12 is inserted into the holes 5b and 11d so that the bottom plate 5 Are superposed on the mounting member 6. When the lever 11 is retracted by the urging force of the coil spring 9b or manually until the supporting members 11c, 11c come into contact with the peripheral edge of the recess 4a, the engaged portion 11e engages with the engaging member 12 in the engaging groove 12a. The bottom plate 5 is fixed to the mounting member 6. Then
The side plate 4 is rotated and raised so that the support members 11c, 11c are inserted into the recesses 4a, 4a, and is set up on the bottom plate 5. Then, the support members 11c and 11c are attached to the side plate 4
To the other side and move the lever 11 back further,
The support members 11c and 11c support the side plate 4 from the other side and return to the initial state of binding the document.

Next, another embodiment relating to the fastening structure of the binder fitting 1 to the binding body 2 will be described with reference to FIG. In this embodiment, the binder metal fitting 1 is fastened to the binding body 2 as follows, so that the binder metal fitting 1 can be relatively easily removed from the binding body 2 when the binding body 2 is discarded. I was able to do it.

FIG. 7 is an explanatory view of the fastening structure of the present invention and is a plan view of the mounting member. FIG. 8 is a sectional view taken along the line I--I of FIG. 7 for explaining the operation of the fastening structure of the present invention. Is a diagram showing a state in which a tool is inserted into a hole, and (b) is a diagram showing a state in which fastening is released. The mounting member 6 is formed with two through holes 6a at symmetrical positions, through which the rivets 3 serving as fastening means can be inserted. From the through hole 6a, a notch 14 having the same shape is formed in the same direction to form a tongue piece 15.
As shown in FIG. 3, the notches 14 are parallel portions 14a, 14a wider than the crushed portion (or head portion) of the rivet 3 that engages with the mounting member 6, and 30 from one end portion of the parallel portions 14a, 14a. Degree to 60 degrees, preferably 40 to 4
At an angle of inclination of 5 degrees, head diagonally toward the through hole 6a,
It is composed of inclined portions 14b and 14b communicating with a.
The tongue piece 15 formed in this way has the mounting member 6 on the base side.
And one end on the side of the through hole 6a,
An arc portion 15a forming a part of the through hole 6a is formed. That is, the crushed portion (or head) of the rivet 3
Is engaged with the peripheral edge of the through hole 6a and the circular arc portion 15a, and is firmly fixed to the binding body 2 (see FIG. 5).

On the base side of the tongue piece 15, as shown in FIG. 8 (a), the tongue piece 15 is projected to the upper surface side of the mounting member 6 to form a convex insertion portion 16. The insertion portion 16 is provided with an opening 1 toward the front end side or the rear end side of the mounting member 6.
6a is formed, and the tip of a tool 17 for lifting a tongue piece such as a driver having a sharp tip can be inserted into the opening 16a. Then, by inserting the tip of the tool 17 into the opening 16a and rotating the tool 17 upward, the base side of the tongue piece 15 is plastically deformed (state of FIG. 8B) and the arc portion 15a is formed. The rivet 3 and the tongue piece 15 are disengaged by retreating.
Since the tongue pieces 15 are formed on the attachment member 6 in the same direction, the binder metal fitting 1 should be moved in the direction of arrow E in FIG. Thus, the engagement between the hole peripheral edge of the through hole 16 and the crushed portion (or head portion) of the rivet 3 can be released. Then, by lifting the binder fitting 1, the binder fitting 1 can be removed from the binding body 2.

[0027]

As described above, the present invention has the following advantages. Even when a large number of documents are bound, the side plate can be tilted to the back plate side to easily make the two-page spread state. Since the document can be bound from the bottom plate side to the upper end height of the side plate, the space between the cover of the binding body and the document can be made as small as possible. Also, even when the binder metal fittings are attached to the cover side, there is only a plate-like advancing / retracting moving member interposed between the mounting member and the bottom plate, so the thickness when the bottom plate is superposed on the mounting member is possible. It can be made as thin as possible, and it is possible to prevent the useless space between the cover of the binding body and the document. Therefore, even when a large number of documents need to be bound and stored in a large number of binding bodies, the storage space can be effectively used. In the case where the first and second urging means are provided, the side plate is automatically rotated to the other side by the movement of the advancing / retreating member in the first stage to be in a spreadable state, and the binder in the second stage is moved. The metal fittings are in an open state where documents can be replaced.
Further, by returning the bottom plate and the side plate to the predetermined positions in this order, the advancing and retracting moving member can automatically return to return the binder metal fitting to the initial binding state, which is convenient.

The one provided with the urging means for constantly urging the advancing / retreating member toward the other end side regulates the advancing / retreating member so as not to move to the one end side due to an impact at the time of dropping or the like. Even when the binding body is dropped from the binding member, the binding member does not open, and an accident that the document is scattered can be prevented.

It is possible to obtain a binder metal piece that can be easily detached from the binding body when discarding the binding body while maintaining the fastening strength between the binding metal piece and the binding body and the appearance of the binding body. In addition, the binding body from which the binder fitting is removed is recycled as resource waste, and the binder fitting is reused, so that adverse effects on the environment and resources can be reduced.
