DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt for preventing collapse of a load used for transporting or storing luggage and for preventing the luggage from dropping during transportation or storage. The length adjustment and the tightening strength can be adjusted satisfactorily, and the tightening force is remarkably superior to the load collapse prevention belt consisting of only elastic members, ensuring extremely stable and strong winding. The present invention relates to a belt for preventing collapse of a load.

[0002]

2. Description of the Related Art Generally, a load on a pallet or the like is prevented from collapsing by winding a stretch film or a belt around a product and fixing the product.

[0003] In this case, the stretch film can change the binding force and the fixing force of the luggage by increasing or decreasing the number of times of winding around the luggage. This is convenient in that an appropriate product fixing force can be secured according to the conditions.

[0004] However, after transporting the luggage, the stretch film is peeled off and the luggage is unraveled, that is, the stretch film once used to prevent the collapse of the load does not return to the original film shape even if it is loosely and crumplely peeled off. In this method, the peeled stretch film cannot be reused,
Expenses and resources were wasted. Furthermore, since the stretched film that has been discarded accumulates without being decomposed, it becomes a problem as industrial waste. On the other hand, in the case of incineration, gas and the like at the time of incineration may have an adverse effect on the human body, which is a problem in health and sanitation.

[0005] Therefore, recently, a method of fixing with a load collapse prevention belt (sheet) which can be used over and over again without the above-mentioned drawbacks, and a hook-and-loop fastener so that the end portions can be easily and quickly connected are provided. Many of the provided belts for preventing collapse of the load are used. This belt is generally used as a belt-shaped woven fabric or a sheet made of a synthetic resin, and is preferable in terms of securing fastening strength. However, since it has no inherent elasticity, it is necessary to prepare a plurality of belts having different lengths in order to secure an appropriate length and tightening strength according to the amount of luggage, which is inconvenient. In addition, the cost is high.

[0006] These belts for preventing collapse of cargo are widely used except when the luggage is large and the winding dimension (length) is insufficient. For example, conversely, when the luggage is small, the belt is also used. If one end of the belt is pulled and tightened, the amount of luggage is small, so the end of the belt is surplus, and the excess belt part hangs down from the luggage and gets in the way, and even if there is danger such as being caught by other objects there were.

On the other hand, in order to compensate for the above-mentioned drawbacks, Japanese Utility Model Application
In Japanese Patent No. 101458 and Design Registration No. 875374, a belt for preventing collapse of a load is formed by cutting a belt-shaped belt or an intermediate portion of a synthetic resin sheet and connecting the cut ends with a short rubber. Has been proposed,
Adjustment of the winding length and tightening strength are ensured by the expansion and contraction of the rubber.

However, since the length and the tightening strength are adjusted only by the short rubber partially provided at the intermediate portion of the belt or the like, the width of expansion and contraction is small and the range of use is limited.
It may be difficult to adopt a large amount of luggage.

[0009] On the other hand, as a similar member, a "bundling device" in which the entire belt-like belt is formed of an elastic member, for example, a sporting device such as ski is bundled into one, so that the partial short rubber is used. Instead of the structure, it is conceivable to apply such a material to give the entire belt for preventing collapse of the load elasticity.

[0010] However, a load collapse prevention belt made of only an elastic material can certainly change and select a wrapping length and a tightening strength by expansion and contraction, but the binding material and the tightening force of the luggage are provided in advance by the elastic material used. Since it is determined by the pulling force and is exerted evenly on the whole of the belt for preventing collapse of the load, depending on the case, no matter how much the belt is tightened, the belt may not be tightly attached to the pin and the collapse of the load may not be effectively prevented. For example, a rubber material that is highly flexible in order to maximize the degree of expansion and contraction cannot be firmly tightened when bundling heavy objects because of its low tensile force. Collapse occurs during transportation. In addition, the flexible material often has a reduced restoring force after repeated use and is in a fully expanded state. In particular, in many cases, the belt becomes a mere belt having no elasticity in a state where it is immediately stretched when used for binding heavy objects. Further, for example, in a case where a plurality of rectangular packages are bundled (see FIG. 1), even if the wrapped cargo collapse prevention belt is strongly pulled and stretched, due to the high frictional resistance due to the presence of the corners of the package, the corners are prevented from being bent. The belt part between the belt edge and the corners is strongly stretched, but the belt beyond the corners is hindered from stretching, resulting in loose tightening between each corner. And strong fastening parts alternately occur.

On the other hand, if a material having a very small degree of elasticity is used to prevent these drawbacks, a strong tightening can be ensured by tightening with only a small dimension, but in this case, the elastic material is provided in advance. A strong pulling force was exerted, and the elongation rate of the entirety of the belt for preventing collapse of the load was reduced by that much, and almost the same as the above-mentioned non-stretchable woven fabric belt and synthetic resin sheet, Use is difficult.

In addition, if the load fixing force is increased or decreased by increasing or decreasing the number of times the load collapse prevention belt is wound around the luggage, such as the stretch film, regardless of the elasticity, the belt can be formed using an extremely long material. (Sheet) must be formed, which increases the manufacturing cost and, above all, inconvenience in handling it.

[0013]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks of the prior art, and is used when transporting or storing luggage. Adjustment can be performed satisfactorily, and the tightening strength is remarkably superior to that of the load collapse prevention belt consisting of only elastic members, ensuring extremely stable and strong winding. It is an object of the present invention to provide an inexpensive belt for preventing collapse of a load, which can effectively prevent the occurrence of such problems.

[0014]

Means adopted by the present invention to solve the above-mentioned problems are as follows.
Along with a locking member at one end in the length direction, a stretchable portion having a male or female hook-and-loop fastener, and a non-stretchable portion provided with a hook-and-loop fastener facing the male or female hook-and-loop fastener, respectively It is characterized by being divided at each end side and continuing.

[0015]

First, when the load collapse prevention belt is wrapped around the luggage and tightened by the elastic portion of the load collapse prevention belt of the present invention, the length adjustment and the tightening strength are mainly adjusted in this portion.

[0016] By adjusting the disposition length, the elasticity of the stretchable material is not varied, and even if the stretchable material having the same elasticity is used,
It is possible to set and change the length adjustment width and the tightening strength adjustment width of the entire load collapse prevention belt very easily.

For example, if the portion is provided about half of the entire length of the belt for preventing the collapse of the load, it can be given an appropriate elasticity. Can be set more easily and freely, such as obtaining an effective binding performance when the load is heavy.

Therefore, by using only one stretchable material having an appropriate thickness and width, or a suitable stretchability and tensile strength, the material is extremely easy to use, rugged, and has an optimal expansion ratio. It is possible to easily and inexpensively manufacture a load collapse prevention belt provided with.

Furthermore, since the stretching is performed at the stretchable portion, since the stretching limit width is short, as described above, the entire long belt uniformly expands and contracts, and the binding force and fixing force of the load are strong no matter how much the belt is tightened. The disadvantage of not being able to do so is reduced.

[0020] Even if the portion repeatedly expands and contracts due to use, the length of the expansion and contraction changes is short and the degree of friction fatigue is small, so that the degree of quality deterioration can be kept low.
Therefore, it is not necessary to suffer such severe damage, and the disadvantage that the restoring force is weakened and the state is extended is reduced.

Next, when the load collapse prevention belt is wound around the luggage and tightened, the non-stretchable portion of the present invention makes it possible to use a non-stretchable portion such as a belt-like woven fabric or a sheet made of synthetic resin which does not have elasticity. High tightening force is secured.

Since the stretchable portion and the non-stretchable portion are separated from each other on each side of the belt-shaped belt and continuous, if any one end of the belt is pulled, the belt for preventing the collapse of the load is provided. The length adjustment and the adjustment of the tightening strength are balanced in the whole, and a firm tightening force is secured.

In this case, if the arrangement ratio of the non-stretchable portion is set in advance in accordance with the length between approximately three corners of the standard size of the load or the pallet to be bundled, Is adopted when bundling square loads (see FIG. 1), and a proper, extremely stable and strong fastening force can be easily obtained. That is, when the collapse prevention belt is wrapped around the product group, the non-stretchable portion directly contacts the corner of the load. The frictional resistance between the non-stretchable portion and the corner of the luggage is lower than the frictional resistance with a stretchable member made of rubber or a synthetic resin material. Therefore, if the end of the belt is pulled and tightened, the non-stretchable portion slides on each corner and is drawn more smoothly. Therefore, the stretch of the belt is hindered by the high frictional resistance of each corner of the load collapse prevention belt made entirely of elastic material, and the loose tightening part and the strong tightening part alternate between each corner. The disadvantage of occurrence is reduced.

The end portions of the stretchable portion and the non-stretchable portion are provided on each side of the belt.
Therefore, for example, while the conventional rubber part connected and arranged at the belt intermediate part had a problem that there was no indication of where it was located after winding and tightening, the position was always predicted It is extremely easy to use in that it can be obtained and specified.

Further, in the above-mentioned conventional belt, when the rubber portion is located on the opposite side (back side) of the load, it turns around the opposite side of the load to correct the looseness of the belt once tightened. It is necessary to check the tension of the rubber part, and then correct the tension of the rubber part, return to the front side of the baggage, and tighten and adjust the entire belt. In this regard, the load collapse prevention belt of the present invention only needs to check the elastic portion provided at a fixed length from the end, and the efficiency of the work required for correction of winding and loosening is greatly improved.

Further, it is not necessary to perform a laborious operation such as cutting the belt intermediate portion and suturing rubber to each of the cut end portions as in the prior art, which is disadvantageous in that the manufacturing operation is complicated and the cost is high. Can be eliminated.

Further, since a locking member is provided at one end in the length direction, the belt end portion of the folded portion can be pulled by using the locking member by the so-called leverage principle.
A stronger winding is ensured as compared with the case where the hook-and-loop fasteners are merely engaged with each other. The work of adjusting the length and adjusting the tightening strength is also extremely easy since it is sufficient to simply increase or decrease the tightening length of the elastic portion.

Further, by folding back the end of the belt inserted through the locking member, the hook-and-loop fasteners provided on the upper surface of each part can be engaged with each other, so that the belt for preventing the collapse of the load can be connected at any position. The engagement and release operations are also simplified.

According to the overall configuration, the belt is more stretchable, can be adjusted in length and tightening strength can be satisfactorily adjusted as compared with a load collapse prevention belt composed of only a non-stretchable member, and the entirety thereof can be adjusted. Can be formed short. Also, when pulling one end of the belt and adjusting the tightening, even if the amount of luggage is small, the end of the belt will not be left over, the excess belt part will hang down from the luggage and hinder, Also, the danger of being caught by another object is eliminated. On the other hand, in comparison with a load collapse prevention belt consisting of only elastic material,
Tightening strength is remarkably excellent, and extremely stable and strong winding can be secured. Furthermore, compared with the short rubber partially provided at the intermediate portion of the belt, there is more room for expansion and contraction, the range of use is expanded, and the present invention can be applied to binding a large amount of luggage.

First and foremost, only the ratio of the stretchable part to the non-stretchable part is arbitrarily selected and connected in accordance with the type, weight and other characteristics of the luggage. This makes it possible to form a belt for preventing collapse of the load, which can extremely properly and effectively prevent a fall or the like.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the drawings and reference numerals shown in the embodiments. (Embodiment 1) FIG. 1 shows a belt 10 for preventing collapse of a load according to the present invention.
This is a first embodiment in which 0 is applied to fix a package.

The belt 100 for preventing collapse of a load according to the present invention is provided with a stretchable portion 2 and a non-stretchable portion 3 which are continuous on each side of the belt. In this embodiment, the overall length is 200 cm and the width is 5 cm, which is longer than the outer circumference 180 cm of the package to be wound.

The stretchable portion 2 is generally made of a strip-shaped stretchable woven fabric made of chemical fibers in consideration of the convenience of manufacture and use, durability, and the like. The width and length of the elastic portion 2 are adjusted according to the purpose of use, and are not specified at all. In this embodiment, the width and the length are 5 cm and 100 cm, respectively (FIG. 2 and FIG. 3). In this embodiment, for convenience of the manufacturing operation, the belt 1 for preventing collapse of the load is used.
One elastic member is used for substantially the entirety of 00. However, as described later, a non-stretchable member is overlapped and sewn on one end side (the left end side in FIG. 2), so that the portion has no stretchability and constitutes a non-stretchable portion 3. Only the remaining other end side portion (right end side in FIG. 2) following this constitutes the elastic portion 2.

The elastic portion 2 on the other end side is pulled back through the through ring 1 at one end to be folded back and engaged, so that the tightening by the elastic portion 2 prevents the entirety of the belt 100 for preventing collapse of the load. Acts with an appropriate strength against, and can effectively bundle luggage. In FIG. 1, both the folded portion that is folded back and engaged through the ring 1 and the unfolded portion below and located on the upper surface of the baggage are formed as elastic portions 2. The entire length of the elastic part 2 is longer than that of the elastic part 2 in the unstretched state, that is, the retracted state shown in FIGS.

A female surface fastener F is provided on substantially the entirety of the load collapse prevention belt 100, that is, on the upper surface of the one elastic member described above. In this case, it is provided over both the elastic part 2 and the non-elastic part 3, and the position where the female surface fastener F is provided in the present invention is not limited at all as long as the convenience of use is ensured. In the case of the present embodiment, the elastic member itself is formed on the male fastener F itself, that is, the male fastener F is formed using an elastic material, and a manufacturing operation of the belt-shaped elastic member having the surface fastener F is performed. Efficiency has been improved. It should be noted that any method of forming or attaching the surface fastener F may be used, and it is needless to say that the male surface fastener F may be formed as the female surface fastener G. Further, in this embodiment, the hook-and-loop fastener F is provided over substantially the entire length of the elastic member. However, the hook-and-loop fastener F is formed at only a part or at a plurality of places at appropriate intervals, for example, near one end or in addition to the center part. You may.

Next, a slightly narrow non-stretchable member is attached from the substantially left end to the middle of the back surface of the one stretchable member, and this portion constitutes the non-stretchable portion 3. I do.

The luggage is more firmly fixed by the non-stretchable portion 3. In the case of the present embodiment, a non-stretchable member is attached also for the purpose of reinforcing the stretchable member, and the non-stretchable portion 3 is formed to be extremely tough by this double structure, thereby preventing the collapse of a heavy load. Can also be effectively prevented. The length and width of the non-stretchable member reinforced to form the non-stretchable portion 3 are not limited to the lengths and widths shown in the present embodiment, but can be appropriately changed depending on the purpose of use. Regarding the material, woven fabric made of synthetic fiber having rigidity is preferable in consideration of convenience of use, but any material can be used as long as it can firmly fix the luggage, is easy to tighten, and is convenient to handle. .

Further, a female fastener G facing the male fastener F is sewn on the right edge of the load collapse prevention belt 100, that is, on the upper surface on the right end of the elastic part 2. The position of the female surface fastener G is set at the end of the elastic member 1 in order to efficiently wind and fix the belt 100 for preventing the collapse of the load, and to facilitate the engagement and release of the surface fasteners F and G. Although it is provided on the side, there is no problem even if it is provided inside away from the end of the elastic portion 2 as long as it is opposed to the male surface fastener F and can be engaged with each other.

The length of the hook-and-loop fastener G is formed to be 15 cm in the present embodiment, but is appropriately determined so that when the baggage is tightened and the baggage is tightened, the locking is not accidentally released. The longer, the stronger the connection becomes.

A handle 4 is projected and fixed to the right end of the load-collapsing prevention belt 100 to facilitate the winding operation, while the left end of the handle 4 is wound and tightened. A metal through ring serving as the locking member 1 is connected and fixed for convenience of operation at the time. The shape and material of the locking member 1 are not limited to those shown in the drawings, but may be L-shaped or any other shape. (Embodiment 2) FIGS. 4 and 5 show a second embodiment of a load collapse prevention belt 100 according to the present invention. The difference from the first embodiment is that the width of the non-stretchable member attached to the back surface of the stretchable member is formed to have the same thickness as the width of the stretchable member. In that it constitutes (Embodiment 3) FIGS. 6 and 7 show a third embodiment of a belt 100 for preventing collapse of a load according to the present invention. The difference between the first and second embodiments is that the elastic part 2 and the non-elastic part 3
Are sewn and integrated only at each material edge, and the hook-and-loop fastener F is provided on the member relating to the elastic portion 2 and provided on the non-elastic portion 3. There is no point.

Finally, referring to FIG. 1, the procedure for wrapping and securing the load collapse prevention belt 100 around the load will be described. When bundling and fixing a plurality of luggage, first, a load collapse prevention belt 100 is wrapped around an appropriate position of the luggage, and the handle 4 and the elastic part 2 are passed through the ring 1 and folded.
Next, the pull-over prevention belt 100 is tightened while pulling the handle 4. When the stretchable portion 2 is sufficiently pulled and the load collapse prevention belt 100 is appropriately stretched to obtain an effective degree of tightening, a male fastener provided on the stretchable portion 2 or the non-stretchable portion 3 is provided. The female surface fastener G of the elastic part 2 is superimposed on F and engaged. As a result, the load collapse prevention belt 100 is extremely strongly fastened, and even if it is a heavy load, it is effectively bundled to prevent the load collapse.

[0042]

The belt for preventing collapse of a load according to the present invention has a locking member at one end in the longitudinal direction, a stretchable portion having a male and female surface fastener, and a male and female surface fastener. Since the non-stretchable parts provided with the opposing hook-and-loop fasteners are separated and continuous at each end side, they are used when transporting or storing luggage, and as a whole have elasticity and length. Adjustment and adjustment of tightening strength can be performed well.

Further, the tightening strength of the belt is significantly superior to that of the load collapse prevention belt made of only the elastic material, and it is possible to secure extremely stable and strong winding.

Further, unlike the conventional belt in which a rubber portion is connected and arranged at the belt intermediate portion, the winding work and the work for correcting the looseness can be easily performed only by checking the elastic portion provided at a fixed length from the end. it can.

Therefore, for example, large or heavy luggage during transportation or storage can be firmly fixed.
It has an excellent effect of effectively preventing the dropping of luggage and the like.
