Description

[Detailed description of the invention] This invention is a binding for a binder in which a binding tool operating body 3 is pivotally attached to both ends 12 and 13 of a binding device main body 2, and a binding ring can be opened and closed by rotating a hook 6. It's about the ingredients.

Conventionally, various methods have been used to open and close binding rings in binder binding tools, but all of them have drawbacks in terms of convenience, technical efficiency, and economic efficiency.

For example, (a), a method in which one end of both boards equipped with opposing binding rings is pivoted and the other is opened in an inverted V-shape.
This is inconvenient because it is necessary to open the board approximately 90 degrees when binding the paper. (b) A method of connecting both boards via a link and sliding them - this is also convenient,
There are problems with stability. (c) A method in which grooves are formed in the bottoms of both substrates and the two substrates are engaged with each other - this method also has drawbacks in terms of technical and economic efficiency. (iv) Other complicated metal items - I am not impressed with this either in terms of technology, economy, and especially resource conservation.

This proposal has been devised to eliminate such drawbacks. Examples thereof will be described below with reference to the drawings.

FIG. 1 is a perspective view of a binding device attached to a cover 1, showing an embodiment of the entire invention. This idea is
Binding main body 2 equipped with binding ring 4 shown in FIG.
It is composed of four parts: the binding tool actuating body 3 shown in the figure, the insertion shaft body 5 shown in FIG. 6, and the latch body 6 shown in FIG. 7. As long as there is a pin for pivotally attaching the latching body 6, assembly is easy.
Therefore, if this is molded from hard synthetic resin, it can be mass-produced at an extremely low cost.

FIG. 2 is a front view of the binding tool operating body 3 opened. The shaft core body 5 inserted and fixed into the operating body 3 has a
Since the latching body 6 is pivoted, when the latching body 6 is removed from the latching protrusion 7 and rotated upward, the binding ring 4' opens together with the operating body 3. After the sheets are loaded, all that is required is to lower the hook 6 and engage the hook 7.

FIG. 3 is a sectional view taken along line A-A' in FIG.
The main structure of the operating body is shown.

(a) The operating body 3 is rotated about the insertion hole 8 into which the insertion portion 16 of the shaft body 5 is inserted. Therefore, the main body of the operating body 3 includes the insertion hole 8 and has a semicircular shape with its center point and the lower contact point 9 as its radius, while the bottom plate of the binding device main body 2 is shaped to encase it.

(b) When binding the paper to the binding ring 4', the binding ring 4'
However, it is necessary to prevent rotation so that it opens at a certain angle. Therefore, by making the tip 10 longer than the distance (radius) between the insertion hole 8, which is the center point of the actuating body 3, and the contact point 9 on the bottom,
The tip 10 of the inner circular part that is integral with the operating body 3 hits the bottom piece 11 of the outer circular part that is integral with the main body 2,
It is configured such that rotation of the actuating body 3 is restrained.

FIG. 4 is a perspective view of the binding tool main body. In addition,
The binding main body 2 is riveted 22 to the cover 1. Below is an exploded view of the four parts that make up the project.
The number of binding rings shall be two or more and shall correspond to the loose-leaf standard. Note that a part of the bottom plate can also be made hollow.

FIG. 5 is a perspective view of the binding tool operating body. One end of the binding tool operating body 3 forms a main shaft 14 that is pivotally attached to the shaft hole 12 of the binding tool main body 2. The insertion hole 8 is for inserting and fixing the insertion part 16 of the actuating body, and is not limited to a square shape, but may be of other shapes for fitting and bonding.

FIG. 6 is a perspective view of the insertion shaft. The main body is pivoted to the clamping part 20 of the hanging body 6 with a shaft pin 17, 18.
The main shaft 15 is pivotally attached to the shaft hole 13, and the insertion part 1
6 is inserted into the insertion hole 8 and fixed.

FIG. 7 is a perspective view of the hook. On one side, the shaft core body is clamped 20, and on the other side, the latching protrusion 7 is clamped 19
Therefore, both are formed into a U-shape. Note that the upper part of the hook 6 is provided with a knob 21 for pulling out and rotating.

Therefore, one main shaft 14 of the binding tool operating body 3 is
The other main shaft 1 is inserted into one shaft hole 12 of the binding device main body 2.
5 is pivotally attached to the shaft hole 13. In addition, the insertion part 16 of the shaft body 5 is inserted into the insertion hole 8 of the actuating body 3 and fixed, so the shaft body 5 and the actuating body 3 are integrated and rotate around both main shafts 14 and 15. be moved. On the other hand, the insertion shaft core 5 is slidably clamped 20 between the U-shaped hooks 6 and pivoted by shaft pins 17 and 18, so that parallel rotation is possible. becomes.

Therefore, when the latch 21 of the latch 6 is pulled and removed from the grip 19 of the latch protrusion 7, the state shown in FIG. 1 will be achieved, and if the knob 21 is further rotated upward, the state shown in FIG. 2 will be achieved. Then, the binding tool operating body 3 opens.

As mentioned above, the present invention is composed of four parts: the main body of the binding device, the operating body, the shaft body, and the hanging body, so the manufacturing process is extremely simple, and it can be molded from strong hard synthetic resin. This allows for inexpensive mass production. Moreover, the method of use is as simple as removing the latching body from the latching protrusion, turning it upward, and then returning it when finished.
Therefore, the binding device of the present invention brings extremely great effects in terms of convenience, technical efficiency, and economic efficiency.
