Abstract

PROBLEM TO BE SOLVED: To overcome a problem of a conventional binder that when a plurality of electric wires C are to be bound by a binder comprising a binding strip 2 and fixing devices 3 for fixing both ends of the strip 2, if one of ends of the binding strip is inserted into the fixing device, the strip can be moved only in the insertion direction resulting in difficulty in positioning, although the wires are desirably to be bound while aligning characters if printed on an external surface of the strip 2 with a position where they are easy to view. SOLUTION: A movable portion 32 to engage with the binding strip is provided movably in a case 31 inside the fixing device 3. Thus, while one of ends of the strip 2 is inserted, the movable portion 32 retreats to a position where it does not engage with the binding strip to allow the end of the strip to be retractably positioned.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding tool for binding a plurality of long objects to be bound, such as electric wires.

[0002]

2. Description of the Related Art As a conventional binding device of this type, for example, a long binding band is disclosed in Japanese Utility Model Laid-Open No. 51-68787.
There is known a binding tool including a fastening tool for fixing both ends of the binding band to each other in a state where the binding band surrounds the object to be bound.
In this case, when one end of the binding band is inserted into the fixing tool, the projection formed continuously on the binding band and the projection of the fixing tool engage with each other, and one end of the binding band can be further pushed, but in the opposite direction. You will not be able to pull it out. When the other end of the binding band is also inserted into the fixing tool in that state, the projection of the binding band and the separate projection of the fixing tool engage with each other, and the other end can be pushed further, but the other end is pulled. I can't get it back. When inserting the other end into the fixed part, if the binding band winds the binding object, the band of the binding band shrinks by pulling out the other end in the direction in which the binding object in the ring becomes firm. Tightened.

In addition to the above publication, such a binding tool is known from, for example, Japanese Patent Publication No. 2949563.

[0004]

DISCLOSURE OF THE INVENTION The conventional tying tool described in the above publication is designed only for binding the objects to be bound. However, for example, when an electric wire is used as the object to be bound, it is desired to display the type of the electric wire on the binding band. Therefore, printing is performed on the outer surface of the binding band, which is the outer side in the state of being wrapped around the binding object. The printing device used for this printing is configured to feed a long tie band wound in a roll shape, print a certain character or symbol on the outer surface, and automatically cut at a predetermined length. . When printing is performed on the binding band with such a printing device, the printing position with respect to the end of the cut binding band is always in a fixed positional relationship.

When actually binding the objects to be bound on the spot using the printed binding band, it is necessary to adjust so that the printing of the binding band can be easily seen. In the above-mentioned conventional binding tool, when one end of the binding band is inserted into the fixing portion, the binding band can be moved only in the inserting direction. for that reason,
If you accidentally insert one end of the tying tool when positioning the tying band at the site, you cannot return the tying band. Have to start over. Therefore, work cannot be performed smoothly. Further, when the binding band is completely removed from the fixing tool, the fixing tool rubs the outer surface of the binding band, and the characters or symbols printed on the outer surface are blurred or disappear.

[0006] In view of the above problems, it is an object of the present invention to provide a binding tool capable of freely positioning the binding band.

[0007]

In order to solve the above-mentioned problems, a binding device according to the present invention comprises a long binding band, and both ends of the binding band are fixed to each other while the binding band surrounds an object to be bound. In a binding tool including a fixing tool, a plurality of protrusions that are arranged in the longitudinal direction to prevent the binding band from moving to one side but allow the binding band to move to the other side along the longitudinal direction of the binding band. One projection row and a second projection row in which a plurality of projections that prevent the binding band from moving to at least the other are arranged side by side in the longitudinal direction are formed on the binding band, and the second projection row is formed. The engaging piece capable of engaging with the protrusion of the second protrusion row is provided on the fixture so as to move to an engaging position for engaging the protrusion of the second protrusion row and a non-engaging position for not engaging with the protrusion, When both ends of the binding band are inserted into the tool, the above-mentioned engaging piece is held in the engaging position and is not engaged. Wherein the movement of the location is prohibited.

According to the above construction, when the engaging piece is in the non-engaging position, the binding band can be freely moved in the inserting / removing direction without being constrained even if one end is inserted into the fixing tool. After the binding band is positioned by the movement, and the other end is further inserted into the fixture, the engagement piece is held at the engagement position and engages with the protrusion of the second protrusion row.

If at least one of the first projection row and the second projection row is divided into a plurality of parallel rows which are symmetrical with respect to the center line of the binding band, the first projection row is divided. The force acting on the row and the force acting on the second projection row overlap on the same line.

Further, the outer surface is the outer surface in the state where the binding band is surrounded by the object to be bound, and the first projection row and the second row
If both the projection row and the projection row are formed on a surface other than the outer surface, the projection row does not get in the way when printing on the outer surface.

The engaging piece may be formed with an engaging claw that engages with the projection of the first projection row.

BEST MODE FOR CARRYING OUT THE INVENTION Referring to FIG. 1, reference numeral 1 is a binding tool according to the present invention. This binding tool 1 is composed of a band-shaped binding band 2 and a fixing tool 3 for fixing both ends of the binding band 2. Both the binding band 2 and the fixture 3 are made of 66 nylon and have flexibility. When a plurality of electric wires C, which are the objects to be bound, are bundled and the binding band 2 is wound so as to surround the electric wires C, and both ends of the binding band 2 are sequentially inserted into the fixture 3, the binding band 2 is attached to the fixture 3. Does not return to the opposite, and the binding band 2 becomes annular. At least one of both ends of the binding band 2 can be pulled out in a direction in which the annular ring is contracted, and if the ends are pulled out properly, the binding band 2 can strongly bind the objects to be bound.

The outer surface of the binding band 2 wound around the electric wire C is the outer surface 21. Characters or symbols representing the type of the electric wire C are printed on the outer surface 21. This print M
Since it is necessary to check the electric wire C later, it is desirable that the electric wire C be located at a position where it can be easily identified from the outside.

By the way, in order to print on the outer surface 21 of the binding band 2, the printer P shown in FIG. 2 is used. The binding band 2 is wound on a reel R, and is sequentially fed out from the end, printed on the outer surface 21, and further automatically cut at a predetermined length.

Referring to FIG. 3, in the binding band 2, two rows of protrusions 2a and 2b are provided on the surface corresponding to the outer surface 21, that is, the surface which becomes the inner side when wound around the electric wire C, in the longitudinal direction of the binding band 2. Are formed parallel to each other. Both protrusion rows 2a / 2
In both b, projections are continuously formed from a surface and an inclined surface that are perpendicular to the longitudinal direction of the binding band 2. However, the projection row 2
The slopes of the slopes of the a and the protrusion rows 2b are opposite to each other.

On the other hand, the fixture 3 comprises a case portion 31 and a movable portion 32, as shown in FIG. A rectangular through hole 33 is formed in the case portion 31. The upper surface and the lower surface of the through hole 33 have through holes 3 respectively.
A groove 34 is formed in a direction perpendicular to the penetrating direction of 3. Then, the movable portion 32 is bent once and the upper and lower ends of the movable portion 32 are inserted into the grooves 34, respectively. Then, the movable portion 32 can move along the groove 34 in a state where the movable portion 32 can move along the groove 34.
Held at 1. It should be noted that the movable portion 32 is formed with an engagement projection 35 on each side surface. However, the engagement protrusions 35 are arranged in two steps, that is, upper and lower stages, and the upper side engagement protrusions 35 and the lower stage engagement protrusions 35 are formed on left and right side surfaces. After the movable portion 32 is held by the case portion 31, the arrow A
The end of the binding band 2 is inserted in the direction.

When inserting one end of the binding band 2 into the fixture 3,
As shown in FIG. 5, the movable portion 32 is retracted to a position where the engagement protrusion 35 does not engage with the protrusion row 2a. Therefore, the binding band 2 can be freely moved in the insertion / removal direction while being inserted into the fixture 3. Then, the print M printed on the outer surface 21 of the binding band 2 is adjusted to a position where it can be easily seen, and the other end is inserted into the fixture 3.

Then, as shown in FIG. 6, the other end of the binding band 2 moves the movable portion 32, and the engaging projection 35 of the movable portion 32 is moved.
Engage with the row of protrusions 2a. At the same time, the other engagement protrusion 35 of the movable portion 32 engages with the protrusion row 2b. As shown in FIG. 7, when the protrusion rows 2 a and 2 b are engaged with the engagement protrusions 35, both ends of the binding band 2 cannot move in the direction in which they are disengaged from the fixture 3. In this state, if both ends of the binding band 2 are pulled out while checking the position of the print M, the binding band 2 will bind the electric wires C strongly. After that, the end of the binding band 2 protruding from the fixture 3 is cut off if necessary, and the binding work is completed.

By the way, in the above embodiment, the binding band 2 is used.
Although one row of protrusions 2a and 2b having different inclination directions are provided on each of the two, as shown in FIG. You may. By arranging in this way, the projection row 2a
・ The force acting on 2b does not shift to the left and right,
Therefore, the fixture 3 does not tilt even if it is tightly bound.

Also, as shown in FIG. 9, when the binding band 2 is first inserted into the fixture 3, the movable portion 32 'is retracted, so that one projection row 2a' should be formed with a slope. Instead, rectangular protrusions may be arranged. By the way, although the binding band 2 and the fixture 3 are both formed of 66 nylon in the above-mentioned embodiment, they may be formed by using, for example, polypropylene, polyethylene, polystyrene, polyacetal, or a polyolefin resin. It may be appropriately selected in consideration of the usage state, ink fixability, flexibility, strength, and the like.
