Description

[Detailed Description of the Invention] 1. Purpose of the Invention The present invention relates to a binding tool for computer paper.

Computer paper usually has marginal holes at both left and right ends and perforations along the rows of holes, so the one hole at each end of this paper stack is shaped like an arch. When the paper is inserted into the ring and bound, the holes may break or tear, and the paper has the drawback of falling out when the paper is placed upright or hung. Therefore, it is an object of the present invention to provide a reinforced binding tool that can securely bind such a weak bundle of computer paper.

2. Structure of the invention The structure and operation of the invention will be explained with reference to the embodiments shown in the drawings.

1 is a cover, 2 is a binding plate installed at one end of this cover, and 8, 8 is a stop hole provided in a convex shape on the inside of this binding metal plate 2. The lower ends of one end portions 9', 9' of the inverted U-shaped binding rings 9, 9 are inserted. The other end portions of the binding rings 9, 9 are bent outward at right angles, and the bent portions 10, 10 form a notched winding portion 1 provided at one outer edge portion of the binding plate 2.
1, 11, and the bent portions 10, 1
0 again horizontally in the direction of one end 9', 9' of the ring to form lever parts 12, 12. The lever portions 12, 12 are hooked onto hooks 13, 13 provided on the other outer edge portions of the binding plate 2. Reference numerals 14 and 14 designate guide shafts protruding adjacent to the stop holes 8 and 8 at appropriate intervals, and the distance between these two is one interval of the holes in the paper.

Therefore, when attempting to bind a bundle of sheets with this binding tool, first unfold the binding rings 9, 9 outward using their bent portions 10, 10 as fulcrums, and then,
Place the paper stack on cover 1. At this time, the binding plate 2
The upwardly protruding guide shafts 14, 14 are now inserted into the first holes in the rows of holes at both ends of the paper bundle. Then, when the binding rings 9, 9 are rotated in the direction of the paper stack using the lever parts 12, 12, one ends 9', 9' of these rings are inserted into the second holes, and the lower ends of the binding rings 9, 9 are inserted into the second hole. Insert into the stop holes 8, 8 of the metal plate 2. Therefore, if the lever part 12 is further pushed down, this will release the handle 13,
13 and fix it.

In this way, the present invention provides a stop hole 8, which is engaged with one end 9' of the binding ring 9 having an inverted U shape, at a suitable position inside the binding metal plate 2 installed at one end of the cover 1, and also provides this stop hole 8 at an appropriate position inside the binding metal plate 2 installed at one end of the cover 1. A guide shaft 14 is provided protrudingly in the hole 8 at a small interval, and one end of the ring 9 and the guide shaft 14 are inserted and attached to the two holes in the row of holes at both ends of the paper bundle, The other ends of the binding rings 9, 9 are bent outward at right angles to form bent parts 10, 10, and further extended from the bent parts and bent horizontally in the direction of one end of the binding rings to form a lever. portions 12, 12 are formed, the bent portion is inserted into and pivotally supported by cut winding portions 11, 11 provided on one outer edge of the binding metal plate, and the lever portion is pivotally supported on the other outer edge of the binding metal plate. Installed handle 1
3 and 13, firstly, it is possible to align and attach the perforation rows of thick paper bundles reliably and quickly, and secondly, it is possible to securely and quickly align and attach the perforation rows of thick paper bundles. Since the section can be attached using four holes, the strength when binding is increased,
Not only will the paper not be cut or torn, but even if one hole is torn, other holes can be installed to prevent the paper from falling out. Thirdly, the four holes will prevent the paper from falling out. Because it prevents bunching, the diameter of the ring can be made narrower, so that paper turning is always done quickly and smoothly, which helps improve office efficiency, and its practical use. The effect is significant.
