Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a binding tool used for files for binding documents such as paper sheets or various printed matter, and particularly for relatively thick catalogs and the like. This invention relates to a binding tool suitable for binding a large amount of.

[Conventional technology]

Generally, this type of binding device has one of a female binding rod and a male binding rod, such as a female binding rod, attached to one side edge of a binding device board attached to the inside of the spine of the file. One comb plate with protruding rods is fixedly erected, and the other comb plate with male rods protruding from the other side edge of the board is removably locked via a tightening means. ing.

By the way, as mentioned above, in such a binding device, one comb plate is fixed, so when the amount of documents to be stapled increases, it is necessary to remove the documents from the fixed comb plate side or move the documents to the fixed comb plate side. The disadvantage is that filing documents is complicated and inconvenient.

Therefore, in order to solve these difficulties, the present applicant has developed a binding tool configured so that either the left or right comb plate can be engaged or detached as desired, such as the Utility Model 53.
We developed and proposed a binding tool as shown in Publication No. 250. This binding tool is provided with a hanging support shaft on the side plates formed on the left and right sides of the board, and a finger hook and a hanging seat are elastically installed in the notches at the top of the left and right comb plates, and the hanging It is constructed by fitting a support shaft and a catch seat in a rotatable and detachable manner. Therefore, by pressing the finger hook provided on the comb plate inward against the board, the desired comb plate can be rotated to the left or right to be attached or detached.

[Problem that the invention seeks to solve]

However, the above-mentioned binding tool still has some drawbacks. In other words, the engagement between the latching catch and the latching support shaft in the above-mentioned binding tool is maintained by the tension of the spring, especially when a large number of documents are to be bound. If the above-mentioned engagement force is insufficient, the binding tool may be accidentally released while loading and unloading files.On the other hand, if the tension of the spring is set sufficiently high to eliminate this problem, There was a problem that the opening and closing operations of the fittings could not be performed smoothly. Furthermore, if the size of the document to be stapled is too large for the binding tool, there is a problem in that the document obstructs the operation of pressing the finger hook inward against the board when opening the binding tool.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a double-opening type binding tool that is stable in its closed state, can be opened and closed smoothly, and has a simple structure.

[Means for solving problems]

In order to achieve the above object, the binding tool according to the present invention has bent portions facing each other on both edges in the longitudinal direction of a rectangular substrate, and a side plate and this side plate are elastically attached to the bent portion. The pressure holding plates to be held are rotatably hinged to each other, and a first flange portion is formed at the free end of the side plate, and the pressure holding plate is composed of a vertical portion and a horizontal stepped portion, and further includes a binding plate. Comb plates each having a tube and a binding rod are provided, and each comb plate is provided with an engaging opposing portion that abuts against the horizontal stepped portion of the pressing holding plate at the lower end thereof, and the first flange of the side plate is provided at the upper end thereof. a second flange portion that fits into the second flange portion, and a concave curved surface that is continuous with the vertical portion and is configured to be formed on the horizontal step portion of the press holding plate and that is continuous with the vertical portion so as to engage with the engagement counter portion. It is characterized by

In this case, if a knob piece is provided at the center of the upper surface of the first flange part of the side plate, and a recess into which the knob piece is fitted is provided at a part of the second flange part of the comb plate corresponding to the knob piece, opening and closing of the binding tool is possible. This makes the operation easier. Further, by providing legs that contact the side plates and the substrate, respectively, at the free ends of the vertical portion and the horizontal stepped portion of the press holding plate, the upright angle of the side plate with respect to the substrate can be accurately maintained at a predetermined angle.

[Effect]

The comb plate is in a state in which the lower end of the comb plate is pressed against the side plate which is rotatably hinged to the bent portion of the board, and is urged upward via the horizontal stepped portion of the holding plate. The second flange portion is press-fitted into the first flange portion of the side plate. Furthermore, when the comb plate is attached to or removed from the side plate, the comb plate is slightly moved upward or downward relative to the side plate via the concave curved surface of the press holding plate. Therefore, when closing the binding tool, the comb plate is firmly held against the side plate via both the flanges,
The binding tool is stably closed. On the other hand, when opening and closing the storage tool, the flange portions of the comb plate and the side plate are easily engaged and disengaged, and the storage tool is smoothly opened and closed.
