2. Description of the Related Art Generally, a binder capable of binding various loose leaves and the like includes a front and back cover sandwiching a spine made of resin or hard paper in the middle, and a metal binding fixed to the inner side of the spine. Tool.
Most binders of this type have a structure in which the binding tool is firmly fixed by rivets driven from the outer surface of the spine.

[0003] However, such a binder is
Because the rivet has a structure that penetrates the spine,
It is difficult to remove only the binding from the spine. For this reason, after all, the binder is discarded in a state in which it is not separated, and it is not possible to sufficiently cope with modern demands for separating and discarding.

Meanwhile, among recent binders, there has been proposed a type in which a binding device is fixed to a spine without using rivets (for example, Utility Model Registration No. 3).
006854). The binding device in this binder is provided with an adhesive layer and a release paper on the lower surface side of the binding device, and the binding device is removed from the release paper to expose the adhesive layer, and the binding device is attached to the inner surface of the spine. It can be fixed to

[0005]

However, such a binder has been devised with the intention of independently treating the cover, which is a constituent member of the binder, and the binding tool, and once binding the binding tool. It is not intended to be able to remove it after gluing it. In this regard, since recent adhesives are composed of a composition having an extremely strong adhesive force, it is extremely difficult to remove only the binding tool from the spine and separate and discard them. On the other hand, when a composition having a low adhesive strength is used as the adhesive layer, another inconvenience occurs in that the binding tool is accidentally detached from the spine.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the inconvenience of the prior art, and has as its object to enable a binding device to be detachably attached to a spine of a binder.
It is an object of the present invention to provide a binder which can easily remove a binding device from a spine cover and easily encourage sorting and disposal in order to reduce recycling and waste.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the binder according to the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view of the binder according to the first embodiment. In this figure, a binder 10 is composed of a binder main body 11 formed using a single resin sheet material, and a binding device 13 fixed to the binder main body 11 via a holding member 12 so as to be separable. I have. Here, the binder body 11 includes a front cover 14, a back cover 15, and a spine 16 disposed between the front covers 14, 15 via thin portions 16A, 16A.

As shown in FIGS. 2 and 3, the holding member 12 is made of an elongated resin sheet made of the same resin material as the binder main body 11. The holding member 12 is fixed by a spot welding portion 20 provided at a contact portion between the outer peripheral side and the spine 16, whereby a certain gap is formed between the holding member 12 and the spine 16. It has become. At two positions along the longitudinal direction of the holding member 12, first and second cutout holes 21 and 22 are formed at intervals corresponding to dimensions between leg members described later. The first notch hole 21 and the second notch hole 22 are formed so as to be continuous, and the second notch hole 2
2 is provided at a position facing the same direction with respect to the first cutout hole 21. In other words, the second cutout holes 22 are configured such that they take an asymmetrical relative position when viewed from the center in the longitudinal direction of the spine 16. Also,
The first notch hole 21 and the second notch hole 22 are formed so that the opening width of each of the first notch hole 21 and the second notch hole 22 is gradually reduced. In the present embodiment, the first notch hole 21 is a substantially circular hole. On the other hand, the second cutout hole 22 is formed as a slit-like hole.

The binding device 13 includes a pair of left and right semicircular binding legs 24, a support 25 for opening and closing the binding legs 24, and two longitudinal ends of the support 25. It comprises a pair of operation pieces 26 (see FIG. 1). Each binding foot 24 can be opened and closed by moving the pair of operation pieces 26 in a direction away from each other, similarly to a known binding tool. Here, the support 25
Has two holes 27 in its longitudinal direction, and each hole 2
The leg members 28 are fixed to the respective members 7.

The leg member 28 has a cylindrical portion 29. The upper end of the cylindrical portion 29 is caulked and fixed to the forming edge of the hole 27, and a flange 30 is integrally provided on the outer peripheral side of the lower end. The diameter of the flange 30 is set smaller than the opening width of the first cutout hole 21 and is provided so as to be receivable in the cutout hole 21, while the diameter of the flange 30 is set larger than the opening width of the second cutout hole 22. The flange 30 passes through the lower surface of the holding member 12 through the second cutout hole 22. Also,
The thickness of the flange 30 is set such that it can forcibly enter the gap between the holding member 12 and the back cover 16 while receiving a certain frictional resistance by the opposing surfaces.

Next, a method of fixing the binding device 13 will be described with reference to FIG.

Holding the binding device 13 in hand, the flange 30 located on the lower surface side is aligned with the first notch hole 21. In this state, each flange 30 is inserted into each first notch hole 2.
The entire binding device 13 is lowered so as to be received in the device 1. At this time, since the opening width of the first cutout hole 21 is set to be larger than the diameter of the flange 30, the work can be performed without difficulty. Next, when the entirety of the binding device 13 is slid so that the flange 30 moves toward the second notch hole 22, the cylindrical portion 29 of the leg member 28 is brought into contact with one edge of the notch hole 21. Fixation is completed. In this state, both surfaces of the flange 30 are in a frictional engagement state by the opposing surfaces of the holding member 12 and the spine 16, and unless a large external force is applied to the opposite side to the sliding direction.
The flange 30 does not move to the first notch hole 21 side and does not fall off. In other words, the binding device 13 can be removed by applying a large external force to the side opposite to the sliding direction when the binding device 13 is fixed.

Therefore, according to this embodiment, the operation for fixing the binding device 13 to the inner surface side of the spine 16 can be performed easily and quickly by hand, and the binding device 13 It is easy to remove, and it is possible to ensure that the binder body 11 and the binding device 13 can be thoroughly separated at the time of disposal.

Next, a second embodiment of the present invention will be described with reference to FIGS. In the following description, the same reference numerals are used for the same or equivalent components as in the first embodiment, and the description is omitted or simplified.

In the second embodiment, the relative positional relationship of the second notch holes 22 is different, and the slide of the binding device can be physically restricted by changing the structure of the corresponding leg member. It has a characteristic in the manner described above.

That is, as shown in FIG. 6, the second notches 22 are formed at both ends in the longitudinal direction of the spine 16, respectively, so that the second notches 22 are mutually separated when viewed from the longitudinal center of the spine 16. It is provided so as to take a symmetrical positional relationship. On the other hand, as shown in FIGS. 7 and 8, a connecting member 35 that fits in a double cylindrical shape with the leg member 28 is separately provided inside the leg member 28.

The connecting member 35 is connected to the cylindrical portion 29 of the leg member 28.
A connecting cylinder 36 having an outer shape that can be inserted therein, a flange 37 formed at the lower end of the connecting cylinder 36, and a screw groove 39 formed along the axial direction from the upper end of the connecting cylinder 36. Have been. A bolt 40 can be screwed from above in a state where the connecting cylinder 36 is fitted into the cylindrical portion 29 of the leg member 28, and the leg member 28 is positioned at a position where the lower surface side of the head of the bolt 40 is seated on the above-described caulking portion. And the connection cylinder 36 can be connected to each other. In the second embodiment, raised portions 12A are formed at both ends in the short width direction of the holding member 12, so that an external appearance in which the support 25 of the binding device 13 is wrapped from both sides can be obtained. ing.

At the time of fixing the binding device 13 in the second embodiment, as shown in FIG. 9, the connecting member 35 is received as a single body in the first notch hole 21, and then the first embodiment is replaced with the first embodiment. It is slid to the second notch hole 22 side in the same manner. In this state, the binding device 13 is lowered from above, and the connection tube 36 is fitted into the cylindrical portion 29 of the leg member 28.

Next, the bolt 40 is inserted through the hole 27 on the support 25 of the binding device 13 and screwed in, thereby completing the connection between the leg member 28 and the connecting member 35,
As a result, the fixing of the binding device 13 to the spine 12 is completed. In the state where the fixing is completed, since the second notch holes 22 are in a symmetrical positional relationship as described above, it is physically impossible to move the binding device 13 in the longitudinal direction, and the bolt 40 Can be removed only by removing the binding device 13.

Therefore, according to the second embodiment, since the binding device 13 cannot be moved, a force may be applied to the binding device 13 from the end of the binding device 13. An additional effect that the possibility that the binding device 13 is accidentally dropped can be reliably avoided. Moreover,
The connection between the leg member 28 and the connection member 35 is made by a bolt 40
In other words, the binding device 13 is removed from the spine 16 only by removing the bolt 40, which is relatively easy, since the structure does not employ the rivet structure that penetrates the spine as in the related art. It is expected that sorting and disposal will be performed reliably.

In the above-described embodiment, the case where two leg members 28 are employed has been described. However, the present invention is not limited to this case. It is possible.

The holding member 12 is made of a single elongated sheet material along the longitudinal direction of the spine 16.
Various modifications can be made, such as using two sheets distributed only in the region where the leg member 28 is fixed.

Further, in fixing the holding member 12 to the inner surface side of the spine 16, it is possible to employ means other than welding, such as bonding. In addition, in the above-described embodiment, the case where the binding device 13 is mounted on the inner surface side of the spine 16 has been described. However, for example, the binding device 13 may be mounted on the base side of the back cover 15.

Also, the first notch 2
The shape of the first and second notch holes 22 is not limited to a continuous shape as in the illustrated configuration example, but a notch is provided therebetween so that the first notch hole 21 and the second notch hole 22 are continuous. May be.

[0030]

As described above, according to the present invention,
Since the binding device can be attached to and detached from the inner surface of the binder body by slide operation, etc., it is possible to perform the separation work of waste very easily, without feeling any stress on general consumers. It is possible to appeal for the encouragement of separation, and it is possible to provide a binder that sufficiently meets modern requirements.

In particular, according to the fixing structure using the holding member in which the position of the second notch is symmetrical, the sliding movement of the binding device 13 is physically restricted. Even if an external force is applied from the direction, the falling off can be effectively prevented.

Further, in the case where the configuration in which the notch forming edge can be sandwiched by the flange of the connecting member and the flange of the leg member is adopted, the fixed state between the holding member and the binding tool can be further stabilized. Can be realized, and the mechanical strength can be improved.
