[Problems to be solved by the invention]

 However, in such a conventional binder, especially when filing or removing the paper sheet, as shown by a two-dot broken line in FIG. 4, the locking rod 13 inserted into the locking groove 11a of one holder 11 is used. When the other end 13b is bent and deformed and pulled out from the engaging groove 11a of the other holder 11 as shown by the solid line arrow in FIG. In operation, for example, when the latching rod is released at the time of bending deformation of the latching rod, the other end 13b of the latching rod 13 is moved by the resilience to jump and jumps. One end 13a often comes out of the locking groove 11a of one of the holders 11 as shown by a dotted arrow in FIG.

The present invention has been made in view of the above-mentioned circumstances, and the present invention has been made in consideration of a situation in which a paper sheet or the like is latched even when careless operation is performed at the time of inserting / removing a latch rod into / from a binder fitting. A main object of the present invention is to provide a binder capable of reliably preventing a rod from coming out of a binder fitting.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, the invention according to claim 1 is to form a binder main body by providing front and back front covers which can be freely opened and closed with a back cover therebetween. In a binder provided with a binder fitting on which a paper sheet is hung and supported on the inner surface side, the binder fitting includes a pair of holders provided at both longitudinal ends of the spine, and faces the respective holders. And an elastically deformable latch rod for latching a paper sheet to be inserted and disengaged at both ends between the respective engagement grooves. An L-shaped bent portion is formed at one end of the stop rod.

[0007] With such a configuration, when filing or removing paper sheets, careless operation when bending and deforming the latch rod during insertion / removal operation, for example, when bending and deforming the latch rod, Even if the latching rod is released, such as when the latching rod is released, the elasticity of the latching rod causes it to jump and jump out of the engaging groove of one of the holders. Since the locking portion thus formed can be locked on the back side of the engagement groove, it is possible to reliably prevent the locking rod from slipping out as before.

According to a second aspect of the present invention, in the binder according to the first aspect, the locking portion is widened in a direction perpendicular to a direction of insertion into the engagement groove. It is characterized in that it has a configuration in which the expansion width and the bending length are at least larger than the groove width of the engagement groove.

With this configuration, it is possible to more reliably prevent the retaining rod from coming off due to an inadvertent operation when filing or removing the paper sheet.

[0010]

[Embodiment of the invention]

 Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings shown in FIGS.

In the illustrated embodiment of the present invention, portions having the same configuration as the binder of the conventional structure shown in FIGS. 3 and 4 will be described using the same reference numerals. FIG. 1 is a perspective view of a retaining rod used in the binder according to the present invention, and FIG. 2 is an enlarged sectional view of a main part.

That is, in the present invention, similarly to the conventional structure shown in FIGS. 3 and 4, for example, a binder body 1 integrally formed of cardboard, plastic, or the like, has a spine 2 interposed between the front and back sides. Covers 3 and 4 are opened and closed so that they can be freely bent, and a binder metal fitting 10 on which paper sheets (not shown) such as pamphlets, catalogs or booklets are latched on the inner surface 2a side of the back cover 2. Is mounted.

The binder fitting 10 has a pair of holders 11 attached to both ends of the inner surface 2 a of the spine 2 of the binder main body 1 in the longitudinal direction by rivets 12, and engagement grooves 11 a opened in the respective holders 11. And both ends 13a, 13b of a thin elastically deformable hooking rod 13 such as a plurality of piano wires, into which paper sheets are hooked between the engaging grooves 11a. To match.

The latching rod 13 has an end portion 13 a that is bent downward in an L-shape to form an engaging portion 14. The engaging portion 14 is inserted into the engaging groove 11 a of the holder 11. It has a configuration in which it is widened in a direction perpendicular to the direction, and its expanded width a and bent length b are larger than at least the groove width c of the engagement groove 11a (a, b). > C) is formed into a substantially circular ring shape.

Next, the operation of the latch rod of the binder in the binder according to the present invention will be described. First, when the latching rod 13 is inserted and engaged between the opposed holders 11 of the binder fitting 10 in advance, as shown by a one-dot broken line in FIG. Is gripped by a finger, and inserted into the engagement groove 11a of one holder 11 while standing upright so that the tip 14a of the locking portion 14 formed on one end 13a thereof is nearly vertical.

As described above, after the locking portion 14 of the locking rod 13 is inserted into the engagement groove 11 a of one of the holders 11, once the locking rod 13 picked with a finger is loosened, the locking rod 13 is in an upward state. The leading end 14a of the locking portion 14 is turned downward by its own weight. In this state, as shown by a two-dot dashed line in FIG. 2, the other end 13b of the holding rod 13 picked by a finger is bent and inserted into the engaging groove 11a of the other holder 11.

At this time, for example, if the other end 13b side of the latching rod 13 picked by a finger is inadvertently released, it is assumed that the latching rod 13 dances to jump by its elasticity. Also, the engaging rod 13 is bent so that the expanded width a and the bent length b of the locking portion 14 are larger than the groove width c of the engaging groove 11a (a, b> c). The one end 13a never gets out of the engagement groove 11a of the holder 11.

When filing papers (not shown) on the binder fitting 10, the papers are hooked on the hooking rod 13, and then the hooking rod 13 is operated in the above-described procedure. As a result, the paper sheet is hung on the binder fitting 10 and filing is performed.

Further, when removing the paper sheets filed on the binder fitting 10, the paper sheets are removed from the binder fitting 10 by operating the latching rod 13 in the reverse procedure of the filing described above. .

In the above-described embodiment, the engaging portion 14 bent at one end 13a of the latching rod 13 is formed in a substantially circular ring shape. However, the present invention is not limited to this. It goes without saying that various changes can be made without departing from the scope of the present invention.
