Description

[Detailed description of the invention] (Field of industrial application) The present invention consists of a binding tool, specifically a board attached to a cover having a front cover and a back cover, and a binding device supported in an upright manner on the board to bind paper pieces. This invention relates to a binding tool consisting of a rod and a presser body that is removably inserted into the binding rod.

(Prior Art) Conventionally, in this type of binding tool, a binding rod is formed separately from a base plate, and the binding rod is fixed to the base plate by caulking so that it cannot tilt.

(Problems to be solved by the invention) However, in the case of the above-mentioned conventional binding tools,
Since the binding rods are fixed to the board so that they cannot tilt, for example, if the number of binding rods is small and the distance between them is large, when binding holes such as pieces of paper to these binding rods, there will be no clogging. After pushing the binding hole through one binding rod, when inserting the remaining binding hole into the other binding rod, the tip of the binding rod and the binding hole will not fit properly unless the piece of paper is kept under tension. First, there was a problem in that the binding of paper pieces into the binding holes in the binding rod was troublesome and could not be easily performed.

The purpose of the present invention is to provide a binding tool in which a binding rod is tiltably erected with respect to a substrate, and by utilizing the tilting movement of the binding rod, it is possible to easily and easily bind pieces of paper onto the binding rod. It is something.

(Means for Solving the Problems) The present invention includes a substrate 3 attached to a cover 2 having a front cover 2a and a back cover 2b, a binding rod 4 supported in an upright manner by the substrate 3 and used to bind paper pieces, and a binding rod 4 for binding paper pieces. The binding tool is composed of a presser body 6 that is removably inserted into the binding rod 4, and the binding rod 4 is tiltably erected on the base plate 3, and the base of the binding rod 4 is attached to the base plate 3. The tilting of the binding rod 4 is caused by engaging with the side of each cover 2.
It is characterized in that an upper plate 5 having a regulating means for regulating swingability only in the width direction of a and 2b is coupled.

(Function) With the above configuration, when binding a piece of paper into a binding tool, by tilting the binding rod 4 inward so as to approach the adjacent binding rod 4, the binding rod 4 can be tightened without forcibly tensioning the piece of paper. The tip can be easily inserted by aligning the tip with the binding hole of the piece of paper.

(Example) The drawing shows a large number of sprocket holes 1a on both sides.
A binding device for continuous slip paper is shown in which a continuous slip paper 1 having a diameter of 10 mm is bound through two sprocket holes 1a on both sides of the continuous slip paper. A mounting plate 31 is fixed to the inner surface of the spine 2c of the cover 2 made of cardboard or the like, and a pivot is pivotally attached to one side of the mounting plate 31 via a first hinge portion 32 extending in the width direction of the cover 2. It is a synthetic resin substrate consisting of a moving plate 33, and the spelling rod 4 is held upright on the swinging plate 33 so as to be swingable.

As a means for holding the spelling rod 4 to the swing plate 33, the attachment hole 3 of the spelling rod 4 in the swing plate 33 is used.

The upper plate 5 has a rod shape with a U-shaped cross section as shown in FIG.
regulation hole 5a, which is an elongated hole that engages with the base side of the binding rod 4 and allows only the tilting of the cover 2 of the binding rod 4 to both sides in the width direction;
At the same time, notches 5b into which the swinging plate 33 is inserted from the side are formed in one side wall at both longitudinal ends of the upper plate 5. It is connected to each rocking plate 33 from its upper surface side by means of a fitting means such as an eyelet fitting.

Reference numeral 6 denotes a presser body 6 that is removably inserted into the binding rods 4, 4, and the presser body 6 is made of a rod-like member having a U-shaped cross section, as shown in FIGS. 8 to 11.
A holding body 61 made of a synthetic resin material having a cut groove 61a is attached to one end of the holding body 61, and one end thereof
The holding hole 61b is formed in the inner part of the cut groove 61a in the holding body 61 and has a smaller diameter than the outer diameter of the spelling rod 4. ing.

Further, in the embodiment shown in the figure, notches 6a are formed at both ends of the presser body 6 through which the binding rods 4 are inserted, and the exposed end of the holding body 61 is formed into a hook shape when viewed from the side. , and the cut groove 61a and the holding hole 61b are formed on the upper and lower opposing surfaces of the hook-shaped portion so as to correspond vertically, so that the holding body 61 can be attached to the presser body 6.
The presser body 6 is fitted along the inner surface of the end thereof, and is connected by a connecting means such as an eyelet fitting with the tip of the presser body 6 being held by the hook-shaped portion.

Further, a locking portion 61c that projects outward is provided on the outside of the exposed end of the holding body 61.

7 is a lock body 7 provided with an engagement recess 7a that detachably engages with the engagement part 61c of the holding body 61;
When the engagement recess 7a is engaged with the locking portion 61c, the holding body 61 is pressed inward to reduce the diameter of the holding hole 61b, and the presser body 6 cannot be moved relative to the binding rod 4. This is done to ensure that the As shown in FIG. 4, the engagement recess 7a of the lock body 7 is adapted to engage with the holder 6 no matter where the holder 6 is positioned on the spelling rod 4. A long engagement protrusion 7b that engages with the locking part 61c of the holder 6 is provided protrudingly on the inner surface near the opening side of the engagement recess 7a.
The lower end portion of the first hinge portion 3 is attached to the swing plate 33.
It is pivotally connected via a second hinge portion 34 that is perpendicular to the second hinge portion 2. Also, the second hinge portion 3 in the lock body 7
A top wall 71 and a side wall 72 are provided at the end opposite to the mounting plate 4 and at one end on the side of the mounting plate 31, and when the lock body 7 is locked to the holder 61, the top wall 71
The side wall 72 covers the tip of the binding rod 4 to prevent it from getting caught with the tip of the binding rod 4 when the bound continuous form is opened toward the front cover 2a, and the side wall 72 covers the end of the binding rod 4. It is configured to cover the end of the slip paper 1 on the binding side.

In the embodiment shown in the figure, the mounting plate 31, the swing plate 33, the lock body 7, the first and second hinge parts 32,
34 is integrally formed of synthetic resin.

When binding the continuous slip form 1 into the binding tool configured as described above, first, the lock body 7 is rotated outward via the second hinge portion 34, and the engagement recess 7a of the lock body 7 is closed. and the locking portion 6 of the holding body 61
Release the lock with 1c. This release makes it possible to expand the cut groove 61a in the holding body 61 outward, that is, to expand the diameter of the holding hole 61b, so the presser body 6 is pulled out from the double-sided rod 4.

Next, the two sprocket holes 1a on both sides of the continuous slip form 1 are inserted into the two binding rods 4. At this time, since both sprocket rods 4 can be tilted to both sides in the width direction of the cover 1 through the regulation holes 5a of the upper plate 5, one sprocket hole 1a
is inserted into one sprocket rod 4, and when inserting the other sprocket hole 1a into the other sprocket rod 4, by tilting the other side sprocket rod 4 inward toward the one side sprocket rod 4. Continuous slip form 1
The sprocket rod 4 can be easily inserted into the sprocket hole 1a by aligning it with the sprocket hole 1a on the other side without forcing the sprocket.

Thereafter, the holding holes 61b of each holding body 61 in the presser body 6 are inserted into the binding rods 4, and the continuous slip paper 1 is pressed against the upper plate 5 by the presser body 6. In this case, since the diameter of the holding hole 61b is smaller than the diameter of the binding rod 4, the presser body 6 is temporarily fixed to both binding rods 4 at the insertion position by the elastic restoring force against the expansion of the cut groove 61a. be done.

Thereafter, by swinging the lock body 7 inward and strongly pressing it, the locking portion 61c of the holding body 61 is engaged with the engagement recess 7a. This engagement presses the holding body 61 inward to reduce the diameter of the holding hole 61b, and
can be immovably locked to the binding rod 4, and the engagement of the engagement recess 7a with the locking part 61 prevents the engagement body 7 from being accidentally removed by external force from the engagement position. This prevents it from opening in the opposite direction.

Also, according to the above binding, the continuous slip form 1 has a large number of sprocket holes 1a formed on both sides.
Among them, only two sprocket holes on both sides 1
In addition to the binding on the binding rod 4 of a, the one end of the binding side can be held over the entire length between the presser plate 6 and the upper plate 5, so that an outward tensile force is applied to the continuous slip form 1. Even if the sprocket hole 1a is damaged, the tensile force will not be concentrated on the sprocket hole 1a portion, so that the sprocket hole 1a portion will not be easily torn.

Furthermore, the continuous slip paper 1 can be stapled up to the tip of the binding rod 4, and therefore the amount of continuous slip paper 1 that can be stapled relative to the height of the binding rod 4 can be increased.

Incidentally, in the above embodiment, a continuous slip form 1 having a large number of sprocket holes 1a on both sides is used as a piece of paper.
sprocket holes 1 on both sides.
Although we have described a binding device in which the letter a is sewn into a pair of binding rods 4, it goes without saying that it can also be applied to pieces of paper with three or more binding holes and binding devices equipped with three or more binding rods. It is.

Furthermore, by forming a rough surface by applying sand blasting or knurling to the surface of the binding rod 4, the retaining body 6 when locked by the locking body 7 is formed.
1 with the binding rod 4 can be further increased, thereby preventing the presser body 6 from floating up from the continuous slip paper 1 due to the movement of the presser body 6 with respect to the binding rod 4, and the binding force can be further increased. Continuous slip paper 1 is attached to sprocket hole 1 by binding only with rod 4.
This can more reliably prevent tearing from part a.

(Effect of the invention) As described above, the binding tool of the present invention has the binding rod 4 on the board 3.
is installed tiltably upright, and at the same time, a regulation is provided on the base plate 3 that engages with the base side of the binding rod 4 to restrict the tilting of the binding rod 4 so that it can swing only in the width direction of each of the covers 2a and 2b. Since the upper plate 5 having a means is combined, when binding pieces of paper onto the binding rod 4, only in the width direction of each cover 2a, 2b of the binding rod 4,
In other words, since the binding rods 4 can be tilted only inward or outward in the arrangement direction, the tips of the binding rods 4 can be easily aligned with the binding holes of the paper pieces without forcibly tensioning the pieces of paper. In addition, since the tilting movement is restricted except in the width direction,
Stapling the paper pieces into the binding rod 4 is easy, and
It can be done quickly.
