Description

[Detailed description of the invention] <Industrial application field> This invention relates to a computer data binding device.

<Conventional technology> Conventionally, when binding computer data into a file, a binding string was passed through a marginal punch hole in the computer data, and then hooked onto binding devices on both sides of the document to secure it. .

<Problems to be solved by the invention> Since the conventional marginal punch hole has a small diameter, the string must be (a) thin;
(b) There should be no bending or breakage due to friction caused by frequent rebinding, (c) It should have excellent flexibility so that it can be attached to the hook of the binding tool, (d) It should not have a tendency to bend when opened. It must have characteristics such as having a repulsive force that allows it to return to an upright position. For this reason, in the past, strings such as nylon were often used,
If used repeatedly, it may break or break.
It also had drawbacks such as not having sufficient flexibility and not being able to hang properly on the hook.

<Means to Solve the Problems> In view of the above problems, this invention uses a wire rope made of thin steel wires twisted together with a synthetic resin coating, and a string that is applied to the surface of the computer data through the cover. A fixed bottom plate with a hole through which the binding string is passed, and a tip that slightly enters the hole when the binding device is closed. The rotating piece has a small hole provided in the bottom plate as a pivot and is always urged toward the hole by a spring.

<Function> Since the string is constructed as described above, it is thin and
To obtain a binding string that is not easily bent or broken due to frequent use, is flexible, has no tendency to bend when opened, and has a repulsive force to return to an upright state.

In addition, the binding tool is biased by a spring so that when the string is passed through the hole, the tip of the rotating piece slightly enters the hole, so the tip bites into the string.
Prevent the string from coming off.

<Example> To explain with reference to figures, Fig. 1 is an external view of a file using the binding device of this invention, in which computer data 3 is bound between a front cover 1 and a back cover 2. The front cover 1 has an opening part 11 that covers the document, and a folding part 12 that folds one side inward and places it on the document. The back cover 2 is also vertically symmetrical and has a similar configuration.

Figure 2 shows the binding part of the file with the opening part 11 of the front cover 1 opened, and the inside folded part 1
2 is placed on the computer data, binding tools 20, 20' are fixed to the folds at both ends thereof, and are combined with the binding string of this invention to lock the string.

FIG. 3A is a perspective view of an embodiment of the binding tool of this invention, and FIG. 3B is a side view of the embodiment, showing the bottom plate 21.
Drill a string insertion hole 22 in the hole, and insert the tip 3 toward the hole.
1 is a rotating piece 30 which is biased by a spring 32 with a small hole 35 provided in a raised part of the bottom plate as a pivot.
A string hooking piece 33 is formed at the other end of the bottom plate. Reference numeral 26 denotes a mounting hole on the bent portion 12 of the front cover 1 of the bottom plate 21. The tip 31 of the rotating piece 30 serves as a restraining edge.

When using, press the rotating piece 30 to release the spring 3.
2 in the counterclockwise direction in FIG. 32 into the hole 22 to secure the string. Even if the string tries to come off downward in the figure, the tip 31 of the holding piece acts as a wedge and a restraining edge to restrain the string from coming off. The tip of the string is hooked onto the hook portion 33.

<Effects of the invention> This invention has the above-mentioned structure, so the string is strong and has sufficient flexibility and repulsion, and the binding tool also has the rotating piece held down by a spring, so the tip of the rotating piece This can strongly prevent the string from coming off.
