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 the prior art] Conventionally, a sixth type of paper has been used for storing loose leaf etc. in a replaceable manner.
A hinge-operated binder binding device l as illustrated in the figure is used. The binder binding device 1 generally includes two longitudinal members 5 and 7, which are integrally provided along the longitudinal direction, with a plurality of semi-annular members that meet in the closed state to form a binding ring 3, at their inner edges. They are joined to each other and restrained by a sheath-shaped spring member 9 along the outer edge so that they are assembled together and can be elastically hinged in the direction of the arrow a.

However, since the binder binding device 1 having such a configuration is manufactured using a special mold having a specific length dimension that matches the existing leaf of a specific size in which it is used, various dimensions other than the specific length may be used. In order to manufacture the binder binding tool 1 for binding the leaves, a new mold must be created each time, which causes an increase in manufacturing costs.

[Object of the Invention] Therefore, an object of the present invention is to provide a connecting binder binding device that can solve the above-mentioned 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, which meet in a closed state to form a wire 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 manufactured by molds of a specific length, and therefore, a binder that can accommodate leaves of various lengths with a small number of molds. It has the effect of making it possible to form a binding tool.

[Description of Embodiment 1] Hereinafter, the present invention will be described in detail 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 longitudinal members 6 and 8 made of plastic 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 wire ring 4 in the closed state. The pair of longitudinal members 6 and 8 are assembled as shown during assembly of the binding, and then the longitudinal edges 14 of the sheath-shaped spring members 12 are inserted into the longitudinal grooves 10 formed in each outer edge. is inserted. The spring member 1
2 provides a resilient force for 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 are integrally integrated as in the prior art, with portions 16 and 18 extending transversely to each other in the respective longitudinal members as shown. It is set up as follows. A finger rest is similarly provided at one end of the other set of longitudinal members.

In the connecting binder binding device 2 of the present invention, the other end of the longitudinal member, that is, the finger hook of each longitudinal member is at the portion 16.
A connecting portion for integrally connecting the two sets of longitudinal members is formed at the end opposite to the side where the longitudinal members and 18 are provided. The connecting portion connects one longitudinal member (
In FIG. 1, it is constituted by an engaging means 20 provided at each end of the longitudinal member 6) and an engaged means 22 provided at the end of the other longitudinal member 8 (see FIG. 2). The engagement means 2o preferably have a hook-like shape projecting from the end of the longitudinal member 6 as shown in FIG. 1 and are integral with the bottom surface 24 of the longitudinal member 6 (see FIG. 3). is formed. On the other hand, the engaging means 22 is preferably a protrusion as illustrated in FIG. The engaging river means 20 provided at the end
is integrally formed at a position such that it can overcome the engaging means 22 and then be resiliently coupled.

FIG. 5 is a completed view of a connecting binder binding device 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 engagement means and support means of said coupling portion and is subsequently assembled with a sheath-like spring member 12. 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, in the connected binder binding device 3° having such a configuration, for example, in order to open the connected binder binding device 30, the finger rest is attached to the portion 1.
The forces applied at 8 and 18° in one set 2 of longitudinal members are applied via the longitudinal members 6 to said engagement means 2.
The longitudinal member 2' is transmitted as a force to push up the longitudinal member 8' through the engaging means provided on the longitudinal member 8' of the pair of connected mating longitudinal members 2'. set 2 of longitudinal members on the one hand and the other on the other hand.
When the longitudinal member 6 is engaged with the longitudinal member 6, the longitudinal member 8 is
is transmitted to the set 2 of the longitudinal members as a pushing force, thereby causing the two sets of longitudinal members to hinge integrally with respect to each other.

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, namely Q+, 122.9s, in addition to each single length binder binding, β1+β1, β1+4□, β1
+β3, 122 +12. , fl□+Q5. It is possible to combine the connecting binder binding devices with six different lengths of β and ten degrees Celsius, and therefore, a total of nine different lengths of connected binder binding devices 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.
