Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file, and more particularly, to an operation for fixing a base of a binding device to a spine or back cover serving as a surface to be fixed. The present invention relates to a file that can be easily performed, and that can separate a binding device and a cover to promote separation and disposal or reuse of the binding device. 2. Description of the Related Art Hitherto, files having a binding device on the inner surface side of a spine or a back cover have been commercially available.
The binding tool used for the files includes, for example, a base, a pair of binding plates disposed on both left and right sides of the base, and a binding rod extending between the binding plates. When the base is fixed to the spine, a plurality of holes are formed at the coaxial line position between the base and the spine, and the base is fixed with rivets through the holes. Has been adopted. [0004] However, in the fixing method using the rivet, a manufacturing facility such as a dedicated rivet driving device or the like is indispensable, and an operation for maintaining an appropriate fixing position is required. Disadvantageously lowers the manufacturing efficiency. In the case of files, the cover side is flammable, while the binding side is usually made of metal to maintain load-bearing performance. Is required. However, in the rivet fixing method, it is difficult to separate them, and in fact, they are discarded without being separated. [0005] Separate disposal has recently been strongly demanded from the viewpoint of recent waste disposal problems or the protection of the natural environment. More preferred. In this respect, for example, a binding device used for a file hardly becomes unusable, and only the front cover is generally obsolete and unusable. [0006] It is an object of the present invention to make it easier to separate and discard, and also to make it easier to reuse parts that are still valuable as parts, that is, binding devices The purpose of the present invention is to provide a file that can contribute to the regulation of the total amount of waste. [0007] In order to achieve the above object, according to the present invention, a binding device including a base and a binding member provided on the base is fixed via a predetermined base fixing device. In a file that is detachably fixed to a surface, the base fixture is an outer member positioned on the outer surface side of the fixed surface, and the fixed member is connected to a surface of the outer member and penetrates the fixed surface. base consists of a standing member having a disengageable claw portion, wherein the upright member for operating rod insertion
A hole is formed, and the upright member always has a claw portion engaged with the base to fix it to the surface to be fixed, while operating within the hole.
Insert the rod and apply external force to tilt the operation rod.
The engagement is released when the upright member is displaced to the inclined posture by the application. According to such a configuration, the base can be detached from the surface to be fixed by releasing the engagement between the claw portion and the base, thereby facilitating separation and disposal or reuse of the binding device. Specifically, for example, a shaft portion of a writing instrument or
Use a screwdriver or the like as an operating rod and insert the end of this into the hole.
By displacing the upright member in the inclination direction,
Can be easily released. An embodiment of a binding device according to the present invention will be described below with reference to the drawings. In this specification, “left and right” are used with reference to the short width direction of the spine shown in FIG. 1 and “up and down” are used with reference to the longitudinal direction of the spine unless otherwise specified. Can be FIG. 1 is a schematic perspective view of a main part of a first embodiment of a file according to the present invention, and FIG.
A partially omitted cross-sectional view along line A is shown. In these drawings, a file binding device 10 includes a base 13 fixed to the inner surface of a spine 11 as a surface to be fixed, and a pair of bases 13 disposed on both left and right sides of the base 13 and capable of being pressed inward. Operating member 15, a shaft pin 17 supported on the left and right sides of the base 13, respectively, and a part of which is held by the operating member 15, and a left and right lower end side of which is detachably provided on the shaft pin 17. A pair of binding plates 20 and 21
And a binding rod 23 as a binding member made of a pipe fixed at two positions on the relative surfaces of the binding plates 20 and 21 and fitted in the axial direction in a telescopic relationship to each other. The binding plates 20 and 21 can be detached from the base 13 by the displacement of the shaft pin 17 when the operation member 15 is pressed inward. Here, the base 13 has one longitudinal end engaged with the positioning member 24, and the other end engaged with the base fixture 25 and fixed to the spine 11. The base 13 has a pair of upper and lower (left and right in FIG. 2) fixed surface portions 26 fixed to upper and lower positions of the spine 11, and an inclined surface portion 26 between these fixed surface portions 26.
And an intermediate surface portion 27 that is provided continuously through the A. Of the fixing surface portions 26, the positioning member 24
An extension piece 27 protruding in the same plane as the fixed surface part 26 is connected to the fixed surface part 26 located on the side, and the outer edge of the extension piece 27 has an upward engaging projection piece 28.
(See FIG. 2). On the other hand, in the other fixed surface portion 26, substantially rectangular holes 29 are formed at two positions in the width direction (the direction perpendicular to the paper surface in FIG. 2). The positioning member 24 has a substantially rectangular plate-shaped outer support piece 30 attached to the outer surface of the spine 11 so as to be in surface contact with the outer cover side, and stands up from the surface of the outer support piece 30. It comprises two upstanding projections 31 extending through holes 11A formed in the spine 11. Each of the upstanding projections 31 has a bent portion 32 at an upper end so as to have a substantially inverted L-shaped cross section, and the engaging projection 28 is engaged with a lower surface of the bent portion 32. . As shown in FIG. 3, the base fixture 25 has an outer member 34 having substantially the same planar shape as the outer support piece 30, and is connected to one surface of the outer member 34 so as to be connected to the outer member 34. It is composed of two upright members 35 extending through holes 11B formed in the spine 11 and holes 29 formed in the fixed surface portion 26. The left side width of the upright member 35 in FIG.
An inclined portion 35 </ b> A that is larger than the inner diameter of 9 is formed. A horizontal surface portion 35B is formed at the lower end of the inclined portion 35A, and the horizontal surface portion 35B is provided with the fixed surface portion 2B.
A claw 37 extending downward in the hole 29 in a state in which it comes into contact with a forming edge of the hole 29 formed in 6 is projected downward. A hole 39 is formed in the upright member 35 from the upper end surface thereof along the upright direction of the upright member 35.
Inside 9, a shaft member 40 as an operation rod composed of familiar objects such as a writing implement shaft or a driver is provided so as to be insertable. In fixing the base 13 to the spine 11 in the above configuration, first, the positioning member 24 and the base fixture 25 are attached to the spine 11. Next, the entire base 13 is set to the inclined posture, and the positioning member 24 is set.
The engagement protrusion 28 of one of the fixed surface portions 26 is inserted into the lower surface of the bent portion 32 of the second engagement portion 32 so as to be engaged. Next, the position of the fixed surface portion 26 on the opposite side is lowered so that the base 13 is in a horizontal posture, so that the upper portion of the upright member 35 enters the hole 29 of the fixed surface portion 26. When a pressing force is applied to the fixed surface portion 26 from above in this state, the upright member 35 is displaced from the initial upright posture to an inclined posture shifted by a predetermined angle due to the presence of the aforementioned inclined portion 35A. ", The formation edge of the hole 29 partially engages with the horizontal portion 35B and the claw portion 37. On the other hand, when removing the base 13 from the spine 11, as shown in FIG. 4, the shaft member 40 is inserted into the hole 39 of the upright member 35, and an external force is applied so as to incline the shaft member 40. By doing so, the upright member 35 can be forcibly displaced in angle to release the above-mentioned engagement state. Therefore, according to such an embodiment, it is possible to fix the base 13 only by pressing the base 13 into the spine 11, and to use the shaft member 40 which is present at hand. The base 13 can be detached by using this method, and the operation of attaching and detaching the base can be performed very easily and quickly without using any special tool. It should be noted that the file according to the present invention is not limited to the above embodiment, and may have a configuration as shown in FIG. 5, for example. In this configuration, the engaging projection 42 is formed on the edge of the fixed surface portion 26, while the claw portion 43 is formed on the right upper portion of the upright member 35 in FIG.
The base 13 is fixed by the engagement of the engagement protrusions 42 with the engagement protrusions 3. In order to release the engagement, the shaft member 40 may be inserted into the hole 45 formed in the upright member 35 and may be inclined in the direction indicated by the two-dot chain line in the figure. Therefore, even with such a configuration, the same operation and effect as those of the above embodiment can be obtained. Further, in the above-described embodiment, one of the fixed surface portions 2 is provided.
Although the case where the base fixing tool 25 is applied to 6 is illustrated and described, the present invention is not limited to this, and the base 13 may be fixed by providing the base fixing tool 25 on each fixing surface portion 26. In this case, the positioning member 24 described above is of course unnecessary. As described above, according to the present invention,
While the base can be fixed by the claw portion of the upright member being engaged with the surface to be fixed, the engagement can be released by applying a forcible external force to the upright member. It is possible to promote separation and disposal or reuse of the binding device by securing the binding device. Further, since the formation of the hole for the operation rod inserted into the upright member, for example, you can use writing instrument shaft portion or driver such as an operation rod, the base of eliminating the need to use special tools Removal becomes easy.
