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. It relates to a binding tool used for binding large quantities of items such as.

[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, for example, as shown in Japanese Utility Model Publication No. 53-250. We have developed and proposed a similar binding tool. This binding tool is
A hanging support shaft is provided on the side plates formed on both the left and right sides of the board, and a finger hook and a catching seat are elastically installed in the notches at the top of the left and right comb plates, and the above-mentioned hanging support shaft and the hanging It is constructed by fitting a catch seat in a rotatable and detachable manner. Therefore, by pressing the finger hook provided on the comb plate inward against the base plate, 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. That is, 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, but especially when a large number of documents are to be bound, If the engagement force is insufficient, the binding tool may be accidentally released while files are being put in or taken out.On the other hand, if the spring tension is set sufficiently high to eliminate this inconvenience, the binding tool will The problem was that the opening and closing operations 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 the following features:
Bent parts are provided oppositely on both longitudinal edges of a rectangular substrate, and a side plate and a pressure holding plate for elastically holding the side plate are rotatably hinged to the bent parts, respectively. A first flange portion is formed at the free end of the press holding plate, and the press holding plate is composed of a vertical portion and a horizontal stepped portion, and further includes a comb plate having a female binding rod and a male binding rod, respectively, and each comb plate is provided with a first flange portion. The lower end portion of the device is provided with an engaging contact portion that abuts against the horizontal stepped portion of the press holding plate, and the upper end portion thereof is provided with a second flange portion that fits into the first flange portion of the side plate. shall be.

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. Furthermore, by forming a recessed curved surface in a portion of the horizontal stepped portion of the press-holding plate that is continuous with the vertical portion, the closed state of the binding tool becomes more stable, and at the same time, the opening and closing operations can be performed more smoothly.

[For production]

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. Further, when the side plate of the comb plate is applied, 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 the storage tool is closed, the comb plate is firmly held against the side plate via both the flanges, and the storage tool is stably closed. On the other hand, when opening and closing the binding tool,
Both the flanges of the comb plate and the side plate can be easily engaged and disengaged, and the binding tool can be smoothly opened and closed.
