BACKGROUND OF THE INVENTION
The present invention relates to a belt provided with a latch used for making a load, preventing collapse of the load, for securing, and the like.
[0002]
[Prior art]
In general, a large number of cardboard boxes containing articles are stacked on a transport pallet or rack (including a rack that also serves as a container), and a pallet or rack is lifted by a transport means such as a forklift, or a rack When storing cardboard boxes, many cardboard boxes stacked on pallets and racks are tied up by lashing belts in the horizontal and / or vertical direction, and the cardboard boxes collapse and fall during transportation. In addition, the stacked pallets and racks are tied together with a belt to prevent them from falling over.
[0003]
Conventionally, there are belts shown in FIG. 9 and FIG. 10 as belts used for packing, preventing collapsing, and securing.
The belt 21 includes a belt main body 22, a hook 23 fixed to both longitudinal ends of the belt main body 22, a hook ring 24, and the both ends of the belt 21 are overlapped with each other. The rubber band 25 is sewn to the end of the main body 22.
[0004]
Then, as shown in FIG. 10, a rubber band 25 is wound around a fixing part 26 such as a pallet or rack cross member, and a hook 23 is engaged with a hook ring 24, and the end of the belt main body 22 is attached to the end of the belt main body 22. The fixing portion 26 is fastened and fixed via a rubber band 25.
[0005]
[Problems to be solved by the invention]
By the way, in the above prior art, the tension T applied to the belt main body in the longitudinal direction directly acts on the rubber band 25 via the hook hook 23 and the hook ring 24. The rubber band 25 does not adhere to the fixing portion 26, and the end portion of the belt main body 22 cannot be positioned and fixed to a rack column or the like. Binding power is reduced.
[0006]
The present invention has been made in view of the actual situation as described above. The purpose of the present invention is to provide tension applied to the belt body even when the belt is wound around the fixing portion via the elastic band. In order to provide a belt capable of preventing the elastic band from being stretched out, maintaining its function and improving the durability, and capable of stably securing luggage. is there.
[0007]
[Means for Solving the Problems]
In the present invention, in order to achieve the above object, the following technical means are taken.
That is, according to the present invention, one of the pair of hooks is provided at one end or both ends or an intermediate part in the longitudinal direction of the belt main body so as to be relatively movable in the longitudinal direction of the belt main body, and the other The latch is fixedly attached to the belt body, and the latch provided so as to be movable and the latch fixture fixing portion of the belt body or the vicinity thereof are connected by an elastic band.
[0008]
Accordingly, when the belt according to the present invention is used, for example, when a plurality of stacked racks are tied and stored or transported, first, when fixing both ends of the belt to a fixing portion, that is, a rack cross member (or support column), Each of the hooks is individually held by hand, wound around the cross member so that the end or middle part of the belt body and the elastic band overlap, and the hooks are engaged with each other. Secure to the material.
[0009]
In this case, the end portion or the intermediate portion of the belt main body is wound around the cross member and engaged with both latches in a form independent of the elastic band. And after the both ends or the intermediate part of the belt body are wound around and fixed to the cross member, the tension acting on the belt body does not act on the elastic band, and the belt body end or The intermediate portion acts as a force for fastening the cross member from the periphery. Therefore, the elastic band tightens the cross member by the elastic force of the band itself, ensures the engagement of the pair of latches, and is not stretched by the tension of the belt body, so that its function is fully exhibited and fully extended. As a result, durability is improved.
[0010]
In addition, the belt main body is not affected by the elasticity (expansion / contraction) of the elastic band, and maintains a required locked state of luggage or the like. In addition, when fixing the end or middle part of the belt body to a support or vertical member such as a rack, the elastic band is wrapped around the support or vertical member and positioned, so even if the belt is not tensioned, The end portion does not slide down and can be securely fixed at a desired position.
[0011]
In addition, when the belt main body and elastic band insertion part of a pair of latches are one, the belt main body is positioned on the inside of the elastic band and wound around the fixing part.
Then, the elastic band is inserted into a movable latch and formed into a loop shape, and both ends thereof can be fixed to the latch fixing portion of the belt body or the vicinity thereof, and the strength of the elastic band can be set high. .
[0012]
Moreover, a pair of latching tool can be comprised with an annular latching tool and a hook-shaped latching tool which has a belt main body insertion part.
Furthermore, at least one of the pair of hooks may be provided with an insertion portion common to the belt main body and the elastic band and an elastic band single insertion portion.
In this case, the belt main body end side latch is only the belt main body insertion portion, so that the belt main body end portion can be wound around the fixing portion such as the support column outside the elastic band.
[0013]
The belt according to the present invention has a pair of latches and elastic bands, as described above, not only at both ends or one end of the belt main body, but only at the intermediate portion of the belt main body, and further on the belt main body. Provided at the intermediate part and one or both ends, so that the appropriate position of the belt body can be positioned securely and firmly in the fixed part (for example, the appropriate position of the rack cross member, support column, pallet, other luggage or goods, etc.) can do.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
1 to 4 show a first embodiment of the present invention, in which a belt 1 is composed of a belt main body 2 made of synthetic resin such as nylon or polypropylene, or a fabric blended with cotton or synthetic leather, and a belt main body 2. Of the metal (or synthetic resin) annular latch 4 and the elastic (rubber) band 5, and the belt body 2 and the elastic band 5 are both relative to each other in the longitudinal direction. It consists of a hook (hook 6) made of metal (or synthetic resin) movably inserted.
[0015]
The belt body 2 is provided with a front / back discriminant line 7 which is a front / back discriminating means extending in the longitudinal direction near one end in the width direction on the front side (or back side). Since the front / back discrimination line 7 does not appear on the front side, the front / back discrimination can be performed.
The annular hook 4 has a substantially rectangular frame shape when viewed from the front, and has a size capable of winding the end portions 2A and 2B of the belt body 2 around one side thereof. The hook-shaped hook 6 includes a hook 6A having a width that can be hooked and engaged with one side of the pair of hooks 4 and a base 6B having a width larger than the width of the belt body 2. The base portion 6B is provided with a belt insertion portion 8 formed of a long hole extending in the width direction.
[0016]
The hook-shaped hook 6 is inserted into the belt insertion portion 8 so that the hook portion 6A is positioned on the front side of the belt body 2, that is, on the discrimination line 7 side, and the elastic band. 5 is inserted.
Then, the end portions 2A and 2B of the belt main body 2 are respectively inserted into the annular hooking device 4 and the ends 9 are folded back. The elastic band 5 is formed in a loop shape and the both end portions 5A and 5B are overlapped. Thus, after being sandwiched between the end portions 2A, 2B of the belt body 2 and the folded ends 9, they are sewn together 3 and integrally connected.
[0017]
Therefore, the annular latch 4 is fixedly attached to the belt main body 2 and the elastic band 5, but the hook-shaped latch 6 is provided so as to be movable relative to the belt main body 2 and the elastic band 5. .
FIG. 2 exemplifies a state in which four container-type racks 10 (see FIG. 4) are stacked and arranged in two stages, and are bound to two rows in the vertical and horizontal directions by the belt 1 according to the present invention. As shown in FIG. 4, the rack 10 has upright pillars 13 made of angle members at the four corners of a base 12 framed in a grid by square pipes 11, and the right and left ends and the rear part of the pillar 13 are angled members. 14 are connected and can be stacked. In FIG. 2, reference numeral 15 denotes a top frame, which is framed like a grid like the base 12.
[0018]
When the rack 10 is bound by the belt 1 of the first embodiment as shown in FIG. 2, the length of the belt main body 2 is set to a required length. It spans back and forth, both ends are hung down, and each end 2A, 2B of the belt body 2 is wound so that its front side is in contact with the square pipe 11 (cross member), as shown in FIG. The hook portion 6A of the hook-shaped hook 6 is engaged with the tool 4.
[0019]
At this time, the elastic band 5 is positioned outside the belt body 2, the square pipe 11 is fastened together with the belt body 2, and the end portions 2 </ b> A and 2 </ b> B of the belt body 2 are positioned and fixed to the square pipe 11. Next, as shown in FIG. 3, the belt main body end 2A of the belt 1 that ties up the horizontal (horizontal) direction is positioned and fixed to the support column 13 in the same manner as described above, and the belt main body 2 is placed around the entire circumference of the rack 10. After winding, the belt body end portion 2B is positioned and fixed to the support column 13.
[0020]
According to the first embodiment, when the rack 10 is tied by the belt 1 as shown in FIG. 2, the tension acting on the belt body 2 is applied to the belt body end 2A via the pair of hooks 4 and 6. , 2B acts as a force for tightening the square pipe 11 and the column 13. The tension of the belt body 2 does not act on the elastic band 5 at all. That is, the elastic band 5 fastens the square pipe 11 and the support column 13 with a constant force only by the elastic force. Therefore, the elastic band 5 is not likely to be extended due to the tension applied to the belt body 2, its function is maintained, and durability is not impaired. In addition, since the elastic band 5 is prevented from being stretched completely, the end portions 2A and 2B of the belt body 2 do not slide down from the support column 13 when the belt body 2 is not tensioned, and the position is reliably fixed. .
[0021]

[0024]
FIGS. 7 and 8 show a third embodiment of the present invention. The difference from the first embodiment is that the elastic band 5 is inserted through the hook-shaped hook 6 in addition to the belt insertion portion 8A. The single insertion part 8B is provided in parallel near the belt insertion part 8A, and the elastic band 5 is hooked by the band hooking part 17 formed between the two insertion parts 8A and 8B.
[0025]
In the third embodiment, when the belt 1 is mounted on the column 13 of the rack 10, as shown in FIG. 8, the elastic band 5 is inside the belt main body end portions 2A and 2B and contacts the column 13. Tighten this. When tension is applied to the belt body 2, the belt body ends 2 </ b> A and 2 </ b> B tighten the support 13 from the outside of the elastic band 5, but the tension of the belt body 2 does not act on the elastic band 5. Therefore, the elastic band 5 does not extend completely, and the same effect as the first embodiment can be expected.
[0026]
7 and 8, components common to the first embodiment are denoted by the same reference numerals as those in FIGS. 1 and 3, and detailed description thereof is omitted.
In the third embodiment, the hook latch 6 has the two insertion portions 8A and 8B. However, the hook latch 6 has one insertion portion 8 at the end of the belt body 2. The center part can be made into an elastic band latching part by making the attachment and the annular latching tool 4 into a front view day shape.
[0027]
Then, the intermediate portion of the belt body 2 can be separated and detachably connected via a length adjuster that is generally used in the past, and according to the size of the luggage or goods, The length can be appropriately adjusted and used.
Further, the elastic band 5 is inserted into one of the hooks and formed into a loop shape, and both ends thereof are fixed in the vicinity of the other hook of the belt body 2, but both ends of the elastic band 5 are not formed in the loop shape. May be fixed to each of the hook stoppers 4 and 6.
[0028]
