Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rope fastener, and more particularly, to a rope fastener in which a rope having a circular cross section is easily tightened around a load or the like so that the rope can be easily loosened. Here, the rope in this specification refers to a rope-like member having a substantially circular cross section with a diameter of about 5 mm to 10 mm.

[0002]

2. Description of the Related Art Conventionally, ropes have been used as fasteners for fixing loads loaded on pallets for cargo handling. Such ropes are formed by knitting vegetable fibers or chemical fibers or forming a long and thin vinyl chloride material, and the cross section is configured to be a circle with a diameter of about 5 mm to 10 mm, and is widely used as a strong and convenient fastening device. Have been. When fixing luggage etc. using this kind of rope,
In general, a bundle of luggage is bundled with a rope, and the ends of the rope are tied together to form a knot. In order to release the fixed state, the knot is released.

Further, the applicant of the present application has already disclosed, as a patent application, an invention of a cylindrical net member in which upper and lower ends and an intermediate portion thereof can be squeezed in order to suitably fix a load carried by a cargo pallet. However, even for ropes used for the purpose of squeezing and shrinking the opening of the cylindrical member or the bag-shaped member in this way, in order to keep the rope in a squeezed state, the ropes are tightened after pulling the rope. It was normal to stop.

[0004]

However, in order to securely fix the luggage, it is necessary to tightly tie the rope so that it cannot be easily unraveled, and it is difficult to release the knot when releasing the luggage. There was a problem of becoming.
Therefore, for example, when a distribution company or the like frequently tightens and releases the luggage, the workability is poor, and an improvement in the method of fixing the luggage with a rope has been required.

[0005] In order to improve the workability of tightening and releasing the luggage with the rope, there have been some proposals concerning a fixing device or a tightening device for easily realizing the tightening and releasing of the rope (for example, Japanese Utility Model Laid-Open No. 7-42791). Gazette). However, any of these attempts lacks certainty of rope tightening, workability, durability, or cost performance, and there is no practical one for fixing work at the time of package delivery in a distribution business, for example.

The present invention has been made in view of this problem, and can be suitably used particularly for the purpose of securing luggage at the time of delivery of luggage in a distribution business, and can be manufactured at a low cost with a simple configuration. An object of the present invention is to provide a rope tightening device that realizes secure tightening and releasing of a rope by an easy operation.

[0007]

SUMMARY OF THE INVENTION To achieve this object, the present invention provides a holding portion for fixedly holding a first rope end and a second rope end being clamped and held at an arbitrary position. A first opening for passing the second rope end portion from the back side of the operation portion to the front side, wherein the first operation portion is formed in a plate shape; The second rope end folded back through the opening,
A first folded portion for further folding back at the edge of the operation portion in the folded direction,
A second opening through which the rope turned back at the turn-back portion is again passed to the front side, and a rope passing through the second opening being connected to a portion of the rope extending from the first opening to the first turn-up portion. And a second folded part for folding back to the back side at the end edge of the operation unit in this direction.

This rope tightening device is used in a state where one end of the rope is tightened to its holding portion and the other end is fixedly passed through the first opening. In use, after the loop formed by the middle portion of the rope is extended to the outside of the load, the rope passed through the first opening is pulled to loosen, and the edge is folded back in the direction in which the rope extends. At the back side, pass again from the second opening to the front side, cross over the portion of the rope extending from the first opening to the first folded portion, and pass twice at the edge in this direction The rope is tightened by folding back to the back side and finally sandwiching it between the operation unit and the rope passed outside the luggage. As will be described in detail later with reference to the accompanying drawings, this operation can be performed as easily as tying the ends of the rope together, and after fastening, securely fix the luggage. Further, by performing the above operation in reverse, it is possible to release the tightening of the rope much more easily than to release the tightening of the ropes. Therefore, it is possible to provide a practical rope tightening tool in a distribution business where the tightening and releasing of the rope are frequently repeated.

Further, in the rope tightening device of the present invention, it is preferable that the first opening is a through hole smaller than a knot provided at an end of the second rope. By configuring the tightening tool in this way, the rope and the tightening tool which are in a loop from the beginning can be put on the load, and the load can be easily tightened by squeezing the end of the rope passing through the first opening. Such a method of use can be suitably used, for example, in a work in which a rope is previously passed through an opening or an intermediate portion of a drawstring or tubular cloth or a net member, and the rope is squeezed to tighten the load.

Further, in the rope tightening device of the present invention, it is preferable that the second opening is a notch formed continuously from an edge opposed to an edge including the second folded portion. . As described above, in the present invention, the second opening is formed as a concave portion, that is, a notch formed continuously from the edge of the fastener, thereby improving workability. That is, when the second opening is formed as a hole, the tip of the rope must be inserted every time the tightening operation is performed. However, if the second opening is formed as a cutout recess, only an arbitrary portion of the rope needs to be addressed. Workability is dramatically improved.

Further, in the rope tightening device of the present invention, it is preferable that the first folded portion is formed as a substantially semicircular concave portion. By configuring the tightening device in this manner, it is easy to position the rope folding-back position during the work, and it is possible to prevent inconvenience such that the rope is shifted during the work and after tightening and the tightened state is released.

[0012] In the rope tightening device of the present invention, a projection having a height approximately equal to the diameter of the rope is provided on the side of the first folded portion from the second opening and on the back side of the operating portion. It is desirable to be provided. As described above, in the present invention, the rope finally folded back to the back side of the fastener is sandwiched and stopped between the rope and the rope that is turned around the outside of the load. Since this pinching force is strongest at a position near the first opening, it is desirable that the rope does not come off from this position after tightening. Therefore, in the present invention, a protrusion functioning as a stopper for the sandwiched rope is provided on the back side of the tightening device so that the tightened state can be reliably maintained.

23 are used to pass the first rope ends in a predetermined order and tighten the rope tightening device 1. The through-holes 21 to 23 have a substantially circular shape, and the diameter of the through-holes varies depending on the thickness of the rope to be applied.

On the other hand, the operation side end 3 has a first opening 31 through which a rope passes, and a first folded portion 32 for folding the rope passed through the first opening 31 and further folding it back. Here, the rope has a second opening 33 for returning the rope folded back to the front side, and a projecting portion 34 projecting to the back side of the rope fastener 1 as shown in FIG.

In the present embodiment, the first opening 31 is formed in a substantially circular shape, and the diameter thereof is the same as that of the through-hole 2 at the holding-side end.
It is configured to be about 7 mm similarly to 1 to 23. The first opening 31 is disposed at a distance from the long sides 35b, 35c of the fastener 1 that are substantially the same as the through-holes 21, 22 of the holding-side end portion 2.

The first folded portion 32 has the operation side end 3
Is formed as a part of the short side 35a, and is formed as a concave portion which is recessed in a substantially semicircular shape. The long side (35b or 35b) of the rope fastener 1 at the first folded portion 32
The distance from c) is shifted from the first opening 31. This is to prevent the ropes that extend when the ropes are actually tightened from overlapping each other.
As shown in (a), the first folded portion 32 is disposed below the first opening 31.

The second opening 33 is provided between the first opening 31 and the operation side end 35a in the longitudinal direction of the rope tightening device 1, and the lower long side of the tightening device 1 shown in FIG. It is configured as a concave portion provided continuously from 35b. That is, the second opening 33 is formed as a notch vertically provided from the lower side 35b of the fastener 1, and the deepest portion is substantially the same as the first folded portion 32 from the lower side 35b of the fastener 1. To a distance of

The height of the protruding portion 34 is substantially the same as the diameter of the rope to be applied, and is about 3 mm to 5 mm in this example. As the projecting portion 34, a fixing screw or the like can be suitably used.

An example of the method of using the rope fastener 1 according to the present invention configured as described above will be described below. First, before the actual use, one end of the rope is fastened to the holding end 2 of the fastener 1. FIG. 2 illustrates this method. As shown in FIG. 2, one end of the rope is passed in the order of the through holes 21, 22, and 23, and
The end of the rope passing therethrough is further folded back from above the portion of the rope extending between the through holes 21 and 22, and inserted into the gap with the fastener 1. Thereafter, when the rope is pulled in the direction of arrow a, the gap is pressed and the rope is fixed. In addition, a knot is formed at the end of the rope so as to reliably prevent the rope from dropping out of the gap or the through holes 21 to 23. By fixing the rope through three places in this way, the load applied to each through hole when the rope is pulled can be dispersed and fixed reliably,
The durability of the rope and the rope fastener 1 can be ensured.

On the other hand, after the other end of the rope is passed through the first opening 31 of the operation side end 3 of the rope tightening tool 1 in advance,
A knot is formed at the end of the rope so that the end does not fall off the fastener 1. Thereby, the rope is configured as a contractible hoop.

An operation method of the rope fastener 1 thus prepared will be described with reference to FIG. In the actual tightening operation, only the operation side end 3 of the tightening tool 1 is operated. Therefore, only the operation side end 3 is shown in FIG. 3 and the illustration of the holding side end 2 is omitted. When the rope and the tightening device 1 configured as described above are wrapped around the outside of the luggage, as shown in FIG. 3A, the rope is pulled through the first opening 31 to remove the slack, and the arrow b Wrap in the direction of. Next, the rope is pressed with a finger in the vicinity of the first opening 31 so that the rope is not loosened, and the rope is hooked on the first folded portion 32 and folded back as shown by an arrow c in FIG. . As described above, since the first folded portion 32 is formed as a concave portion, the rope can be easily positioned, and does not come off from the concave portion even after tightening.

Next, as shown by an arrow d in FIG.
The rope that has been turned to the back side is again brought out from the second opening 33 to the front side, and folded upward at a substantially right angle. Here, since the second opening 33 is formed as a notch, it is only necessary to hook a rope, and the work can be facilitated as compared with a case where the second opening 33 is formed as a circular through-hole. it can. Next, as shown by an arrow e in FIG. 3D, the rope folded back upward is folded back three times at the upper edge 35 c (second folded portion) of the fastener 1, and finally outside the luggage. It is sandwiched between the extending rope portion 40a and the rope fastener 1. At this time, the rope folded back is brought to the first opening 31 side so that the rope extends between the first opening 31 and the protrusion 34 projecting to the back side of the fastener 1.

FIG. 4 is a view of the state shown in FIG. When the above operation is performed, the finally folded rope end 40b is positioned between the fastener 1 and the portion 40a of the rope turned around the outside of the load, and between the first opening 31 and the protrusion 34. It is sandwiched between. By sandwiching the rope end 40b in this manner, the rope portion 40a is pulled in the direction of the arrow b when the baggage is tightened.
b is firmly fixed and does not shift. In addition, since the protrusion 34 has a height approximately equal to the diameter of the rope to be applied, and the rope end 40b is pressed against the tightening tool 1, the rope end 40b once sandwiched between the rope end 40b and the protrusion is The locking state does not come off beyond the outside beyond. Further, the first opening 31, the first folded portion 32, and the second
Each of the opening 33 and the upper end side (second folded portion) 35c of the fastener 1 serves as a non-slip, so that the rope can be securely fixed.

In order to release the tightened state of the rope tightening tool 1, a rope 40 extending outside the load shown in FIG.
a is pushed away from the fastener 1 or the operating end 3 of the fastener 1 is pulled forward to create a gap between the rope 40a and the fastener 1. Then rope end 40b
Is operated to move over the protruding portion 34, and the procedure shown in FIG. 3 is reversed to release the locked state of the rope. The tightened state can be easily released by this simple procedure.

In this embodiment, the case where one end of one rope is fixed to the holding side end 2 and the other end of the rope is tightly held at the operation side end 3 is described. It is also possible to use different ropes for the purpose of connecting the ropes by fixing different ropes to the holding side end 2 and the operation side end 3, respectively.

FIG. 5 is a view showing an example of use of the rope fastener 1 according to the present invention. As described above, the rope tightening device 1 can be used alone to tighten around the outside of the luggage, but as shown in FIG.
It can be suitably used as a tightening tool for a rope passed through the upper and lower openings and the intermediate part thereof. This net member 50
Is formed in a size that can completely wrap the load 56 loaded on the pallet 55 for cargo handling, and ropes 51 to 53 are non-fixedly sewn into upper and lower openings and an intermediate portion thereof. . These ropes 51 to 53 are held in an annular shape by the rope tightening device 1 of the present invention, and the knot is formed at the rope end passing through the first opening 31 as described above. I won't. A locking member 57 that locks to the pallet 55 is attached to the rope 52 that passes through the lower opening of the net member 50.

At the time of fixing the load on the pallet, first, the net member 50 is completely covered with the load, then the locking member 57 is hooked on the pallet 55, and the lower rope 52 is squeezed and tightened. Thereby, the net member 5
0 and the load 56 can be securely placed on the pallet. Further, by squeezing and tightening the upper rope 51, the load 56 is pressed down from above and fixed. Finally, the rope 53 passed through the middle portion is squeezed and tightened to securely fix the load.
