Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a file opening and closing device for binding a large number of paper pieces.

[0002]

[Prior art]

 Conventionally, as a file opening / closing device, there are a device that opens and closes by rotating a binding rod and a structure that opens and closes by sliding a binding rod when a paper piece enters and exits. However, in each of the conventional examples, a strong force is applied in the closing direction, so that a stronger force is required to open the opening. There was a disadvantage that it took time to get in and out.

[0003]

[Problems to be solved by the invention]

 The present invention addresses the above-described disadvantages of the conventional example. The purpose of the present invention is to eliminate the need for a strong force, to easily open and close the binding rod, and to easily insert and remove a piece of paper. It is an object of the present invention to provide a device for opening and closing a file.

[0004]

[Means for Solving the Problems]

 The file opening and closing device according to the present invention includes a substrate fixed to a center plate of the file, a slide plate sliding in a concave notch provided on the bottom surface of the substrate, and a pair of slide plates that are opened and closed by sliding of the slide plate. Is composed of two sets of flexible binding rods, a pair of support cylinders are provided on the upper surface of the substrate, and a pair of supporting cylinders are provided on the upper surface of the substrate. A knob is loosely fitted in a long hole formed in the substrate to allow sliding, and each of the binding rods is formed by connecting an outer plate and a lower inner plate at an upper end at an upper end, and forming an upper portion thereof. The pair is inserted into two sets of support cylinders by protruding, fixed to the support cylinder via the outer plate, and the lower part of the inner plate is loosely fitted into a groove provided on the inner surface of the substrate. A pin at the lower end of the inner plate is loosely fitted into a slide hole formed by a horizontal portion and an inclined portion of the slide plate. .

[0005]

[Action]

 In the file opening / closing device of the present invention, when the movable knob is moved in a state where the upper portion of the binding rod is curved at a right angle and the pair of opposing binding rods is closed and closed, the slide plate slides. As a result, the binding force of the binding rod to the inner plate is released, the upper portion of the binding rod rotates vertically, and the pair of binding rods that are in contact opens vertically so that a paper piece can be inserted and removed. .

【Example】

 Hereinafter, embodiments of the present invention will be described in detail. Reference numeral 1 denotes a substrate, which is fixed to the center 3 of the file 2. On the upper surface of the substrate 1, there are provided two pairs of four support cylinders 4. Reference numeral 5 denotes a slide plate, which is loosely fitted into a concave notch 6 provided on the bottom surface of the substrate 1, and an operation movable knob 7 protruding from the upper surface of the slide plate 5 has an elongated hole formed in the substrate 1. The slide plate 5 is loosely fitted to and protrudes from the upper surface, and the slide plate 5 is slidably provided in the recess 6 of the substrate 1. Reference numeral 9 denotes a four-piece flexible binding rod which is formed by connecting an outer plate 10 and an inner plate 11 at an upper end portion, and a lower portion of the inner plate 11 is formed to be curved inward and to be elongated. ing. The upper end of each binding rod 9 is inserted into the supporting cylinder 4 from the lower part to protrude, and the projection 12 formed on the outer plate 10 is fitted into the recess 13 formed on the outside of the lower end of the supporting cylinder 4 and stopped. The lower part of the inner plate 11 is loosely fitted in a groove 14 provided in the concave notch 6 of the substrate 1, and a pin 15 formed on the lower surface of the lower end of the inner plate 11 has a sliding hole 16 formed in the slide plate 5. Are loosely fitted. The sliding hole 16 includes a parallel portion 17 and an inclined portion 18 with respect to the sliding direction of the slide plate 5, and is provided corresponding to each binding rod 9. When the pin 15 of the inner plate 11 is located at the outer end of the inclined portion 18 of the sliding hole 16, the upper portions of the pair of binding rods 9 are vertically opened, but the sliding plate 5 is open. When the pin 15 slides and the pin 15 moves from the inclined portion 18 of the sliding hole 16 to the parallel portion 17, the inner plate 11 is attracted, whereby the upper portions of the pair of binding rods 9, 9 are moved inward. It abuts in a right-angled manner and is closed. Reference numeral 19 denotes a paper sheet, which is inserted into the opened binding rod 9 and locked by the support tube 4.

Next, a series of operations of the embodiment will be described. 3 and 4, the bin 15 of the inner plate 11 of each binding rod 9 is located in the parallel portion 17 of the sliding hole 16 of the slide plate 5, and the inner plate 11 of each binding rod 9 is pulled inward. As a result, the upper portion of each binding rod 9 rotates downward and bends at a right angle, and the pair of binding rods 9, 9 abuts and closes, so that the paper piece 19 cannot enter or exit. In this state, when the movable knob 7 is moved in the elongated hole 8, the slide plate 5 slides in the concave notch 6 of the substrate 1, and the pin 15 of the inner plate 11 of the binding rod 9 slides in the slide hole. In the inside of the space 16, the parallel portion 17 moves to the inclined portion 18. When the pin 15 moves, the attraction force of the binding rod 9 against the inner plate 11 is released, and the upper part of each binding rod 9 rotates vertically upward, and the pair of binding rods 9, 9 that are in contact with each other. 5 is opened, and the state shown in FIG. 5 and FIG. In this state, when the movable knob 7 is moved, the slide plate 5 slides in the recessed portion 6 of the substrate 1, and the pin 15 of the inner plate 11 of the binding rod 9 moves in the slide hole 16 through the inclined portion 18. The inner plate 11 of each binding rod 9 moves to the parallel portion 17 and is attracted inward by the moved pin 15, and the upper part of each binding rod 9 rotates downward to bend in a right angle to form a pair of bindings. The rods 9 are brought into contact and closed, and return to the state of FIGS.

[Effect of the invention]

 In the file opening and closing device according to the present invention, as is apparent from the description of the above embodiment, the sliding plate slides when the movable knob is moved, and the binding rod opens and closes by the sliding of the sliding plate. No strong force is required for opening and closing, and the binding rod is vertical at the time of opening, so that it is easy to insert and remove paper pieces and easy to operate.
