Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a binder binding device, and more particularly to the structure of a connected binder binding device.

[Description of prior art]

Hitherto, a hinge-operated binder binding tool 1 as illustrated in FIG. 6 has been used for releasably binding loose leaves and the like. The binder binding tool 1
In general, two longitudinal members 5 and 7, which are integrally provided along the longitudinal direction with a plurality of semi-annular members which meet in the closed state to form the ring 3, are joined to each other at their inner edges. They are combined together by being restrained by a sheath-shaped spring member 9 along the outer edge, and are configured to be elastically hinged in the direction of arrow a.

However, the binder binding tool 1 with such a configuration is
A binder binding device for binding leaves of various dimensions other than these specific lengths because it is manufactured using a special mold with a specific length dimension that matches the existing leaves of specific dimensions. 1, a new mold must be created each time, which causes an increase in manufacturing costs.

[Purpose of the invention]

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a connecting binder binding device that can solve the aforementioned problems.

Another object of the present invention is to provide a connected binder binding device that can provide binder binding devices of many different lengths with a small number of molds.

[Summary of the Invention] According to the present invention, a pair of longitudinal members each having a plurality of semi-annular members integrally provided along the longitudinal direction that meet in a closed state to form a bound ring, are provided at their inner edges. The joints are connected in the longitudinal direction via a connecting part, and their outer edges are restrained by a sheath-like spring member so that they can be hinged integrally. The means for engaging and the means for being engaged provided at one end of each of the longitudinal members and the means for being engaged and the means for being engaged provided at the corresponding ends of the other set of longitudinal members are mutually latched. A connected binder binding tool is provided, which is characterized in that it is configured by: According to the above configuration, in the connected binder binding device of the present invention, the force for opening and closing the binder applied to the longitudinal members of one set is effectively applied to the longitudinal members of the other set via the connecting portion. Because of the transmission, it is possible to combine binder binding devices of different length dimensions produced by molds of a specific length, and therefore leafs of various lengths can be produced by a small number of molds. This has the effect of making it possible to form a binder binding tool that can handle the following.

[Explanation of Examples]

The present invention will be described in detail below with reference to FIGS. 1 to 5. FIG. 1 illustrates a connecting binder binding device 2 of the present invention. The connecting binder binding device 2 conventionally includes a pair of plastic longitudinal members 6 and 8 joined at their inner edges, and a sheath-shaped member that constrains their outer edges and provides elasticity for hinge operation. It is made up of a metal spring member 12. The longitudinal members 6 and 8 are integrally provided along the longitudinal direction with a plurality of semi-annular members that fit together to form the binding ring 4 when the members are closed. The pair of longitudinal members 6 and 8 are assembled as shown when assembling the binding device, and
The longitudinal edges 14 of the sheath-like spring elements 12 are then inserted into the longitudinal grooves 10 formed in each outer edge. The spring member 12 provides a resilient force for the hinge operation of the pair of longitudinal members 6 and 8 in the direction of arrow a. (Note that only one set of longitudinal members is illustrated in FIGS. 1, 3, and 4.) One end (the right end in FIG. 1) of the longitudinal members of one set, that is, the longitudinal members 6 and 8. At each end, finger hooks 16 and 18 for opening the connecting binder binding device 2 extend in a crosswise manner in the mutual transverse direction of the respective longitudinal members as shown in the figure, and are integrated as in the past. provided. A finger rest is similarly provided at one end of the other set of longitudinal members.

In the connected binder binding tool 2 of the present invention, two sets of A connection is formed to connect the longitudinal members together. The connection comprises means for engagement 20 provided at each end of one of the longitudinal members (longitudinal member 6 in FIG. 1).
and an engaging means 22 (see FIG. 2) provided at the end of the other longitudinal member 8. The engagement means 20 preferably have the shape of a hook projecting from the end of the longitudinal member 6 as shown in FIG.
(See Figure 3). On the other hand, the engaging means 22 is preferably a protrusion as illustrated in FIG. The engaging means 20 provided at the end are integrally formed in such a position that they can overcome the engaged means 22 and then be resiliently connected.

FIG. 5 is a completed view of an interlocking binder binding tool 30 formed by connecting two sets of longitudinal members of the present invention. Each set of longitudinal members 2 and 2' is connected by mutual engagement of the respective engaging and engaged means of said connecting portions and is then connected to the sheath-shaped spring member 1.
Combined with 2. The sheath-shaped spring member 12 is inserted into the groove in the outer edge of each set of connected longitudinal members as described above, and provides a resilient force for the opening and closing operation of the connected binder binding device 30. Provides lateral support for each longitudinal member during operation.

Therefore, the connected binder binding device 30 having such a configuration
For example, the force applied to the finger hooks 18 and 18' to open the connected binder binding device 30 is
In one set of longitudinal members 2, it is transmitted via the longitudinal member 6 to said engagement means 20, which is then provided in the longitudinal member 8' of the other connected set of longitudinal members 2'. It is transmitted to the longitudinal member 2' as a force pushing up the longitudinal member 8' through the engaged means provided in the longitudinal member 2', while in the other set of longitudinal members 2', the force is transmitted to the longitudinal member 2' via the longitudinal member 6'. A force for pushing up the longitudinal members 8 is transmitted to the set 2 of longitudinal members through the engaging means provided on the side of the longitudinal members 8, so that the two sets of longitudinal members are integrally connected to each other. The hinge will operate.

According to the connecting binder binding device of the present invention, connecting binder binding devices of various lengths can be provided by connecting longitudinal members of different lengths to each other.
For example, by simply creating three longitudinal members of three lengths, l ₁ , l ₂ , l ₃ , in addition to each single length binder binding, l ₁ +l ₁ , l ₁ +l ₂ , l ₁ +
It is possible to combine them as a connecting binder binding device with six different lengths: l ₃ , l ₂ + l ₂ , l ₂ + l ₃ , and l ₃ + l ₃ ,
Thus, a total of nine different lengths of interlocking binder bindings can be provided.

Although the invention has been described with reference to specific examples, it should be remembered that many modifications may be made thereto.
