[0001]

[Technical field to which the invention belongs]

 The present invention relates to a binding device, and more particularly to, for example, a binding device which is attached to a file and binds by holding a document or the like.

[0002]

[Prior art]

 FIG. 8 is an illustrative view showing a main part of a conventional binding device. The binding device 1 includes a plate-shaped base 2. A side wall 3 is formed integrally with one end of the base 2 in the width direction. A support plate 4 is formed on the base 2 in parallel with the side wall 3. A support shaft 5 is formed between the side wall 3 and the support plate 4, and a torsion coil spring 6 is attached to the support shaft 5 so as to be wound. One end of the torsion coil spring 6 is connected to a holding body (not shown). An operation lever 7 is attached to the other end of the torsion coil spring 6. The operation lever 7 includes a side member 7 a facing the side wall 3. By operating the operation lever 7, one end side of the torsion coil spring 6 moves so as to draw an arc, and the holding body is opened and closed. When the operation lever 7 is pressed down toward the base 2 while the object to be held is held between the holding body and the base 2, the torsion coil spring 6 is wound and compressed. Then, since the torsion coil spring 6 attempts to restore to the original state, the holding member is urged toward the base 2 by the restoring force. As a result, a held object such as a document is firmly held between the holding body and the base 2. At this time, the operation lever 7 is engaged by hooking a projection provided on the side wall 3 of the base 2 into an engagement hole provided on the side surface member 7a.

[0003]

[Problems to be solved by the invention]

 However, when the operation lever 7 is engaged with the side wall 3, the restoring force for restoring the original state of the torsion coil spring 6 which is compressed in the rolled state is also applied to the operation lever 7. work. Then, since the side member 7b of the operation lever 7 that does not face the side wall 3 is not engaged anywhere, it is pushed up in a direction away from the base 2 as compared with the side member 7a side engaged with the side wall 3. Also, due to the structure of the torsion coil spring 6, the distance between the end connected to the operation lever 7 and the opposite side diametrically opposite to the side wall 3 is determined by the distance between the end connected to the operation lever 7 and the side wall 3. It is easier to spread than the distance between Therefore, the operation lever 7 tends to be inclined obliquely with respect to the base 2 as shown in FIG. In this case, since the protrusion provided on the side wall 3 of the base 2 and the engaging hole provided on the side member 7a of the operation lever 7 are separated from each other, the engaging may be unstable. In addition, the state in which the operation lever 7 is inclined obliquely looks unsatisfactory.

[0004] Therefore, a main object of the present invention is to provide a binding device that can securely engage the operation lever and the side wall of the base and has a good appearance.

[0005]

[Embodiment of the invention]

 1 and 2 are perspective views showing an example of the binding device of the present invention. FIG. 1 is a perspective view showing a closed state, and FIG. 2 is a perspective view showing an open state. The binding device 10 includes a base 12 formed in a rectangular plate shape by, for example, a metal plate. A side wall 14 is formed at one end of the base 12 in the width direction. The side wall 14 is formed to stand upright with respect to the base 12 from one end side to the other end side in the longitudinal direction of the base 12.

In addition, three support plates 16, 18, and 20 are formed on the base 12 in parallel with the side wall 14. The support plates 16, 18, and 20 are formed, for example, by forming a cut in a part of the base 12 and raising the cut portion on the base 12. Through holes are formed in these support plates 16, 18 and 20. Support arms 22 and 24 are formed so as to pass through the through holes of the support plates 16 and 18 from the side wall 14. The support arms 22 and 24 are bent at the support plates 16 and 18 and extend so as to be parallel to the surfaces of the support plates 16 and 18, and further bent so that the front ends thereof are substantially perpendicular to the surfaces of the support plates 16 and 18. It is formed so that it becomes. The support arms 22 and 24 are rotatably mounted with the support portions of the side wall 14 and the support plates 16 and 18 as fulcrums. Therefore, when the support arms 22 and 24 rotate, the tip ends move in a circular arc.

A holding body 26 is attached to the distal ends of the support arms 22 and 24. The holding body 26 is formed in a rectangular shape, and holds a document by sandwiching the document with the base 12. The distal ends of the support arms 22 and 24 are attached to the side surfaces of the holding body 26 at both ends in the longitudinal direction of the holding body 26. Further, a support shaft 28 is attached between the side wall 14 and the other support plate 20. A torsion coil spring 30 is rotatably mounted so as to be wound around the support shaft 28.

One end of the torsion coil spring 30 extends parallel to the surface of the support plate 20 and is bent so as to be substantially perpendicular to the surface of the support plate 20. Then, one end of the torsion coil spring 30 is connected to the holding body 26. Further, an operation lever 32 is formed near the support shaft 28. The other end of the torsion coil spring 30 is connected to the operation lever 32. Further, a protrusion 34 is formed on a side surface of the side wall 14 as shown in FIG. At a portion corresponding to the projection 34, an engagement hole 36 is formed on a side surface of the operation lever 32. The projection 34 and the engagement hole 36 constitute the engagement means of this embodiment. By fitting the projection 34 of the side wall 14 into the engaging hole 36 of the holding body 26 in a state where the operation lever 32 is tilted, the holding body 26 is engaged in a state where the holding body 26 is tilted.

The binding device 10 is used by being attached to a file with rivets or the like through a through hole 40 formed in the base 12. In the binding device 10, the holding member 26 can be opened and closed via the torsion coil spring 30 by opening and closing the operation lever 32. When the holding body 26 is closed, the operation lever 32 is tilted to fit the protrusion 34 into the engagement hole 36, and the holding body 26 is urged toward the base 12 by the torsion coil spring 30. Documents and the like are held between the base 12 and the holding body 26 by the force of the torsion coil spring 30. Further, by raising the operation lever 32, the holding body 26 is opened via the torsion coil spring 30, and the document can be removed. Further, in the binding device 10, when the document is sandwiched, two alignment members 38 are formed so as to be substantially orthogonal to the base 12 in order to align the edges of the document. These alignment members 38 are formed by forming cuts in the base 12 and raising the cuts on the base 12, similarly to the support plates 16, 18 and 20.

FIG. 3 is a perspective view showing an operation lever of the binding device shown in FIG. FIG. 4 is an illustrative view showing a main part of the binding device shown in FIG. 1. The operation lever 32 has a substantially U-shaped cross section. The operation lever 32 is formed by integrally forming two side members 32a and 32b on both sides of a single elongated plate member arranged substantially parallel to the base 12. The two side members 32a and 32b are arranged to extend substantially parallel to the side wall 14 of the base 12, the side member 32a is arranged on the side wall 14 side, and the side member 32b is arranged on the holding body 26 side. The above-mentioned engagement hole 36 is formed penetrating the side surface member 32a. A holding piece 42 that is bent in a ring shape to hold the other end of the torsion coil spring 30 is formed integrally with the side surface member 32a. Further, a mounting hole 44 is formed through one end of the side member 32a. The support shaft 28 is inserted into the mounting hole 44. The protrusion 46 of the binding device 10 of this embodiment is formed by deforming the vicinity of the mounting hole 44 of the side surface member 32a into a substantially U-shape. As shown in FIG. 4, when the operation lever 32 is in the engaged state, the protrusion 46 abuts on the base 12 side of the torsion coil spring 30, and the base 12 side of the side surface member 32a is always in the side wall 14 side. It is formed to push in the direction.

In the binding device 10, the side member 32 a of the operation lever 32 is pushed toward the side wall 14 by the protrusion 46 formed on the base 12 side of the side member 32 a of the operation lever 32 in the engaged state. The side member 32a and the side wall 14 are less likely to be inadvertently separated from each other, and can be securely engaged with the projection 34 and the engagement hole 36 as the engagement means. In addition, the side wall 14 and the side surface member 32a are kept substantially parallel by pushing the base 12 side of the side surface member 32a of the operation lever 32 toward the side wall 14 by the protrusion 46, so that the appearance is improved.

FIG. 5 is a perspective view showing a modification of the operation lever, and FIG. 6 is an illustrative view showing a main part of a binding device using the operation lever shown in FIG. The operation lever 32 'shown in FIG. 5 differs from the operation lever shown in FIG. 3 in the shape of the projection 46'. The projection 46 'is formed by bending one end of the side member 32a into a substantially rectangular shape. As shown in FIG. 6, this projection 46 'also abuts against the torsion coil spring 30, and constantly pushes the base 12 side of the side surface member 32a toward the side wall 14. As a result, the side surface member 32a is maintained substantially parallel to the side wall 14, so that the inclination of the operation lever 32 'is corrected and the side member 32a is engaged in a predetermined posture.

FIG. 7 is an illustrative view showing a main part of another modification of the binding device of the present invention. The binding device 10 "has a shape of the operation lever 32 and a shape of the screw coil spring 50 different from those of the binding device 10 shown in Fig. 1. The operation lever 32" of the binding device 10 "is shown in Fig. 1. Unlike the operation lever 32 of the binding device 10, it is similar to the operation lever 7 of the conventional binding device 1 in that it does not have the protrusion 46 at one end of the side member 32a. Are wound around the side wall 14 and the holding body 26 with a substantially V-shaped space 52 therebetween. The interval 52 is formed so as to extend toward the base 12 when the operation lever 32 is engaged. Therefore, the torsion coil spring 50 also acts as a push spring for urging the base 12 side of the side surface member 32a toward the side wall 14. At least the base 12 side of the side wall 14 of the torsion coil spring 50 is in contact with the side surface member 32 a of the operation lever 32. Therefore, the side member 32a and the side wall 14 are not easily separated from each other, and the engagement between the projection 34 and the engagement hole 36 can be reliably performed. In addition, the side wall 14 and the side surface member 32a of the operation lever 32 are kept substantially parallel, and the inclination of the operation lever 32 is corrected.
