Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastener for a packing strap, and more particularly, to a fastener for fixing two intersecting straps with a single fastener.

[0002]

2. Description of the Related Art Fixing devices for fixing one packing strap at both ends when a load is wound with the packing strap are already known. It is, for example, Jitsuko Sho 43-2391
No. 4 publication.

Japanese Utility Model Publication No. 43-23914 introduces the above-mentioned fixture under the name of a luggage tightening band stopper. The stopper is a suitable fastener when a flat band such as a polypropylene band is used as the packing strap.

The stopper introduced in Japanese Utility Model Publication No. 43-23914 has a structure as shown in FIG. In FIG. 1, (a) shows the planar shape of the stopper, (b) shows the side surface shape, and (c) shows the usage state. The stopper has locking pieces 2 and 3 integrally formed on a frame 1 with a thin portion 4 made of synthetic resin. Therefore, the locking pieces 2 and 3 can be bent by the thin portion 4 and stacked on the frame 1, and when stacked, the locking pieces 2 and 3 are stretched around the hole 5 of the frame 1 and extend in parallel with each other.

This stopper was used as shown in FIG. 1 (c). First, the band a is wound around the luggage x, the end of the band a is bent into a U-shape 6, and the frame 1
Through the hole 5 and then insert the locking piece 2 into the U-shape 6, and then pull the end b of the band a in the direction of arrow c to form the U-shape 6.
Was tightened, the locking piece 2 was drawn to the frame 1, and the band a was sandwiched between the frame 1 and the locking piece 2 to be locked. Similarly, the other end of the band a was also locked between the frame 1 and the locking piece 3. In this way, both ends of the band a are tightly fixed by the stoppers, so that the load x is fixed to the band a.
Could be wrapped in.

As shown in FIG. 1, the conventional fastening tool for packing straps has only two locking pieces attached to one frame. So I could only fix one band. Therefore, when it was necessary to wrap the luggage x in a cross shape with bands, each band had to be fixed with another fixing tool. However, when fixing with another fixing device in this way, two fixing devices are required to hang the band in a cross shape, and not only is the banding troublesome, but the tie between the two bands is not necessary. Since each band does not exist, each band moves vertically in the winding direction and there is a drawback that the packaging cannot be performed firmly.

[0007]

The present invention has been made in an attempt to improve the above-mentioned drawbacks. That is,
According to the present invention, a band wound in the vertical direction and a band wound in the horizontal direction can be simultaneously fixed by one fixing device, and therefore, according to this fixing device, the two bands are displaced from each other. An object of the present invention is to provide a fixture that can be firmly fixed so that it does not exist.

[0008]

In order to achieve the above object, the present invention is characterized in that four locking pieces are attached to one frame in a bendable manner. Further, according to the present invention, when the four locking pieces are bent, they can be overlapped with each other on the frame and are squeezed around the holes of the frame. In this state, among the four locking pieces, Facing each other 2
The individual locking pieces extend in parallel with each other, and the two adjacent locking pieces extend in directions intersecting with each other.

The present invention comprises one frame having a hole for passing the packing strap and four locking pieces for hooking an end of the packing strap to make a U-turn. Is molded with synthetic resin integrally with the frame by the thin-walled part, the thin-walled part is bent so that each locking piece can be overlapped with the frame, and each locking piece is framed when the locking pieces are overlapped with the frame. Two of the four locking pieces, which face each other and are opposed to each other, extend in parallel with each other in the longitudinal direction, and between the adjacent locking pieces. The gist of the present invention is a fixture for a packing strap, which is characterized in that it extends in a direction in which the longitudinal directions intersect.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The following will explain one embodiment of the present invention with reference to the drawings. FIG. 2 shows a fixture for a packing strap according to the present invention, and FIG. 3 shows a usage state of the fixture shown in FIG. FIG. 4 shows another fastener for a packing strap according to the present invention.

In FIG. 2, (a) shows a plan view of the fixing tool, and (b) shows a side view in which a part of the locking piece of the fixing tool shown in (a) is overlaid on a frame. There is. In FIG.
The fixture is composed of a frame 11 and four locking pieces 12 to 15, and each locking piece 12 to 15 is flexibly connected by a thin portion 16. Frame 11, locking piece 12
Nos. 15 to 15 and the thin portion 16 are integrally formed of the same thermoplastic resin.

Various kinds of thermoplastic resins can be used. Among them, it is preferable to use polyolefin, especially polypropylene. This is because when the polyolefin, especially polypropylene is used, the thin portion 16 has a strong resistance to bending.

The thin portion 16 is located outside the frame 11. By bending the thin portion 16, all the locking pieces 12 to 15 can be stacked on the frame 11. The state where the locking pieces 12 and 13 are overlapped on the frame 11 is shown in FIG. The locking pieces 12 to 15 are the frame 11
When overlaid, the locking piece is in a state of being laid around the hole 17 formed in the frame. That is, each of the locking pieces 12 to 15 has the raised portion 18 located at both ends thereof in the frame 1.
1, the outer surface of the narrow portion at the center is brought close to the inner wall surface of the frame 11, and a gap is provided between them to bend and pass the packing strap.

Each of the locking pieces 12 to 15 is for hooking an end of the packing strap to make a U-turn.
In a state where the four locking pieces 12 to 15 are superposed on the frame 11, two of the four locking pieces facing each other extend in parallel with each other in the longitudinal direction.
Specifically, the locking piece 12 and the locking piece 14 extend in parallel with each other in the longitudinal direction to form one set, and the locking piece 13 and the locking piece 15 have their respective longitudinal directions. Another set is made by extending the directions in parallel. On the other hand, the adjacent locking pieces extend in the direction intersecting the respective longitudinal directions. That is, for example, the locking piece 12 and the locking piece 13 are locking pieces belonging to different groups, but the longitudinal directions of the locking pieces extend perpendicularly to each other.

When the locking pieces 12 to 15 are superposed on the frame 11, the locking pieces do not collide with each other. Each of the locking pieces 12 to 15 has a raised portion 18 at both ends. The raised portion 18 is for preventing the cord band hooked on the locking piece from moving in the width direction and coming off the locking piece.

In FIG. 2, the hole 17 provided in the frame 11 has a cross shape. This is to prevent the cord passed through the hole 17 from moving in the width direction. That is, the hole 17
Since it is intended to be fixed through both ends of the two cords, four ends of the cords must be inserted. In order to facilitate this insertion, the hole diameter must be made large, but if the hole diameter is made large, there is room for the end of the cord to move in the width direction, making locking difficult. Therefore, in order to prevent the strap from moving in the width direction, a recess is provided so that the strap is recessed in the recess. Due to the formation of the depression, the hole 17 has a cross shape.

The fixture shown in FIG. 2 is used in a state as shown in FIG. In FIG. 3, the fixture according to the invention is used to fix a flat strip for packing. The band is, for example, a band made of polypropylene.

FIG. 3 shows a state in which the luggage x is wrapped by the band a. In FIG. 3, one side a2 of the band a
Is folded in a U shape, and the folded end is the hole 1 of the frame 11.
The baggage x is clearly seen in 7. Next, the locking piece 13 is moved in the direction in which it overlaps the frame 11, and is inserted into the folded U-shaped portion. At this time, the end of the band a is
2 so that the opposite of the luggage x comes to the body of the band a. When the band a2 is pulled in the direction of arrow b in this state,
As described with reference to FIG. 1, the slack of the U-shaped portion is reduced, and the locking piece 13 is strongly pulled by the frame 11, whereby the band a2 is locked between the frame 11 and the locking piece 13. . In the same manner, the other end of the band locks the cord a4 between the frame 11 and the locking piece 15. Thus, the band a can package the luggage x. Until this state,
The fixture according to the present invention is no different from the conventional stopper shown in FIG.

The fixing device according to the present invention is different from the conventional stopper in that not only a single band is fixed,
The point is that the other band can be fixed in the intersecting direction. That is, as shown in FIG. 3, for example, where one side a1 and the other side a3 are already fixed by one band a, another one band a is passed through the same fixture and the one side a2 And the other side a4 can be fixed. In this way, the fixing tool according to the present invention fixes the two bands in the same frame 11 by passing the two bands in the intersecting direction. By doing so, the two bands can be firmly fixed without being displaced from each other. In this respect, the effect of the present invention is great.

The connected state of the frame 11 and the locking pieces 12 to 15 is not limited to that shown in FIG. In FIG. 3, the locking pieces 12 to 15 are arranged axially symmetrically with respect to the frame 11, but they can also be arranged symmetrically with respect to the plane as shown in FIG.
Further, the form of the frame 11 does not need to be provided with a cross-shaped hole as in FIG. 3, and may be a square hole as shown in FIG. Further, the locking pieces 12 to 15 may have irregularities on the surface to prevent the band from slipping.

As the packing strap, a strap having a circular or irregular cross section can be used in addition to the flat strap. The string may be a string having a circular cross section obtained by rolling a stretched polyolefin tape in the width direction,
Alternatively, a rounded string may be further twisted to form a rope. When using a rope-shaped cord, as shown in the locking pieces 13 and 15 of FIG. 4, a notch 19 for accommodating the rope is provided on the locking piece so that a thick rope has a cutout 19.
You may make it fall into the inside. Further, the frame 11 may be provided with a notch 20 corresponding to the notch 19, and the notch 20 may cooperate with the notch 19 to stably hold the rope.

[0022]

According to the present invention, since one frame and four locking pieces are formed, and each locking piece is molded of synthetic resin integrally with the frame by the thin portion, this fixing tool is one. It can be easily made with a mold. Also, by bending the thin portion, it is possible to superimpose four locking pieces on the frame. When each locking piece is superposed on the frame, each locking piece is squeezed around the hole of the frame. Of the four locking pieces, the two locking pieces facing each other extend the respective longitudinal directions in parallel to each other, so that both ends of one packing cord are folded back in a U shape, By inserting the locking piece through the frame through the folding part and then pulling both ends together, the cords can be stretched and fixed between the locking pieces extending in parallel with each other. Further, among the four locking pieces, the two locking pieces facing each other extend in the longitudinal direction in parallel with each other, and the adjacent locking pieces extend in the direction in which the longitudinal directions intersect. Therefore, the two packing straps can be passed through one frame and fixed in a crossed state.
In this way, the luggage can be packaged by crossing the two cords in a cross shape with one fixing tool. Up to now, two fasteners have been required for packaging in a cross shape, but according to the present invention, it is convenient to use only one fastener. . Not only that, according to the present invention, the two straps are fixed by the single fixing tool, so that the two straps cannot be displaced relative to each other, and thus the packaging is more reliable. Is obtained. The present invention provides such benefits.
