Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cargo collapse prevention belt for use in transporting or storing luggage and for preventing the luggage from dropping during transportation or storage, and in particular, has a stretchable length as a whole. Adjustable and tightening strength can be satisfactorily adjusted, and the tightening force is remarkably superior to the anti-collapse belt consisting of only elastic members. It is about.
[0002]
[Prior art]
In order to prevent the collapse of cargo loaded on a pallet or the like, a stretch film or a belt is generally wound around a product and fixed.
[0003]
In this case, since the stretch film can change the binding force and fixing force of the luggage by increasing or decreasing the number of times of winding around the luggage, it can be changed according to a variety of luggage situations such as heavy or light objects, many or few pieces This is convenient in that an appropriate product fixing force can be secured.
[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 peeled off and cluttered randomly, so this method However, the peeled stretch film could not be reused, resulting in waste of resources and resources. 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 belt (sheet) for preventing collapse of a load which can be used repeatedly without the above-mentioned drawbacks, and a load provided with a hook-and-loop fastener so that end portions can be connected easily and quickly. Many collapse prevention belts are used. This belt is generally used as a belt-shaped woven fabric or a sheet made of a synthetic resin, and is suitable 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 used at one end of the belt. If the sides are pulled and tightened, the amount of luggage is small, so that the end of the belt is left behind, and the excess belt part hangs down from the luggage and becomes obstructive, and there is also a danger of being caught by other objects.
[0007]
On the other hand, in order to make up for the above-mentioned drawbacks, in Japanese Utility Model Application Laid-Open No. 60-101458 and Japanese Patent Application No. 875374, a belt-shaped belt or an intermediate portion of a synthetic resin sheet is cut out, and each of the cut-out sections is cut. A load collapse prevention belt in which the ends are connected by short rubber has been proposed, and the expansion and contraction of the rubber ensures adjustment of the winding length and secures the tightening strength.
[0008]
However, in order to adjust the length and the tightening strength only with the short rubber provided partially in the middle part of the belt or the like, the width of expansion and contraction is small, the utilization range is limited, and it may be difficult to adopt for binding a large amount of luggage. is there.
[0009]
On the other hand, as a similar member, a "bundling tool" in which sports equipment such as skis is bundled into one, for example, in which the entire belt-shaped belt is formed of an elastic member, is seen. It is also conceivable to apply such a material to make the entire belt for preventing collapse of the load elastic.
[0010]
However, although the belt for preventing collapse of cargo made of only elastic material can certainly change the wrapping length and tightening strength as appropriate by expansion and contraction, the binding force and the tightening force of the luggage are the pulling force of the elastic material used in advance. Since it is determined and exerted evenly on the entire load collapse prevention belt, depending on the case, no matter how much the belt is tightened, the belt may not be tightly attached to the pins and the load collapse may not be effectively prevented. For example, a rubber material that is highly flexible to have a very high degree of expansion and contraction cannot be firmly tightened when binding heavy objects because of its low tensile force. The cargo collapses on the way. 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 of being 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 the corners. And strong fastening parts alternately occur.
[0011]
On the other hand, if a material with 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. The expansion rate of the entire belt for preventing collapse of the load is low by that much, and it is difficult to use it widely, almost in the same manner as the woven fabric belt and the synthetic resin sheet without elasticity described above. It is.
[0012]
In addition, irrespective of elasticity, 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, the belt (sheet) using an extremely long material is used. Must be formed, the production cost increases, and above all, the handling is inconvenient.
[0013]
[Problems to be solved by 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, and has excellent elasticity as a whole to adjust the length and adjust the tightening strength satisfactorily. In addition to being able to secure, extremely stable tightening strength can be secured as compared with a load collapse prevention belt consisting of only elastic members, and extremely stable and strong wrapping can be secured, and it is possible to effectively prevent falling of luggage during transportation and storage. It is an object of the present invention to provide an inexpensive belt for preventing collapse of a load.
[0014]
[Means for Solving the Problems]
Means adopted by the present invention in order to solve the above-mentioned problems include a locking member at one end in the length direction, a stretchable portion having one of male and female surface fasteners, and a stretchable portion having one of the male and female surface fasteners. A non-elastic part provided with a hook-and-loop fastener, and a non-elastic member having a lower friction resistance than the elastic part on the back surface is sewn on each side, and is divided into each end side and continuous. It is characterized by the following.
[0015]
[Action]
First, when the load collapse prevention belt is wound 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 the relevant portion.
[0016]
By adjusting the length of the belt, it is possible to adjust the overall length of the belt for preventing the collapse of the load even if the stretchable material has the same stretchability, rather than differing the stretchability of the stretchable material. The width of adjustment of the width and the tightening strength can be set and changed very easily.
[0017]
For example, if the portion is provided about half of the entire length of the belt for preventing collapse of the load, moderate elasticity can be imparted. On the other hand, if it is provided in one-third, the pulling force and elasticity are more restricted. In addition, it is possible to easily and freely set such that effective binding performance can be obtained when the load is heavy.
[0018]
Therefore, by using only one stretchable material having an appropriate thickness and width, or a suitable stretchability and tensile strength in the material, it is extremely easy to use, sturdy, and furthermore, has an optimal stretch ratio. The load collapse prevention belt can be easily and inexpensively manufactured.
[0019]
Furthermore, since the stretching is performed at the stretchable portion, the stretchable width is short, so that the long belt as described above uniformly expands and contracts, and no matter how much tightening the baggage binding force and fixing force are not increased. Disadvantages are reduced.
[0020]
And even if the part repeatedly undergoes expansion and contraction fluctuations due to use, the length of the expansion and contraction fluctuation 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.
[0021]
Next, when the belt for preventing collapse of the load is wrapped around the luggage and tightened, the non-stretchable portion of the present invention provides a firm tightening force such as a belt-like woven fabric or a sheet made of a synthetic resin that does not have elasticity in its entirety. Is secured.
[0022]
The stretchable portion and the non-stretchable portion are separated from each other on each end side of the belt-shaped belt and are continuous, so that if any one end of the belt is pulled, the entirety of the belt for preventing the collapse of the load can be obtained. The balanced length adjustment and the adjustment of the tightening strength are performed, and a firm tightening force is secured.
[0023]
In this case, if the arrangement ratio of the non-stretchable portion is set in advance according to the length between approximately three corners of the standard size of the luggage or the transport pallet to be bundled, this becomes a square shape. By adopting it when bundling a luggage (see FIG. 1), an appropriate, extremely stable and strong tightening force can be easily obtained for the whole. That is, when the collapse prevention belt is wrapped around the product group, the non-stretchable portion directly comes into contact with the corner of the luggage. The frictional resistance between the non-stretchable part and the corner of the luggage is lower than the frictional resistance with the elastic member made of rubber or 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 anti-collapse belt made entirely of elastic material, and the loose and strong fastening parts alternate between each corner. The disadvantage of occurrence is reduced.
[0024]
The end portions of the stretchable portion and the non-stretchable portion are provided on each end side of the belt. Therefore, for example, while the conventional rubber part connected and arranged at the belt intermediate part had a problem such as having no idea where it was located after winding and tightening, the position was always predicted It is very easy to use because it can be obtained and specified.
[0025]
Further, in the above-mentioned conventional belt, when the rubber portion is located on the opposite side (back side) of the load, the rubber portion turns to the opposite side of the load to correct the looseness of the belt once tightened. It is necessary to check the state of tension, and then to correct the tension of the rubber portion, 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 thereof, and the efficiency of work required for correction of winding and loosening is greatly improved.
[0026]
Further, it is not necessary to perform a troublesome operation such as cutting the belt intermediate portion and suturing each of the cut end portions with rubber as in the related art, and eliminates the drawbacks of complicated manufacturing work and high cost. It becomes possible.
[0027]
In addition, 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 according to the so-called leverage principle, so that the hook-and-loop fasteners are simply engaged with each other. In this case, a stronger winding is ensured as compared with the above-described method. The work of adjusting the length and adjusting the tightening strength is also extremely easy because it is sufficient to simply increase or decrease the tightening length of the elastic portion.
[0028]
Further, by folding back the end of the belt inserted through the locking member, the hook-and-loop fastener provided on the upper surface of each part can be engaged with each other, and the belt for preventing the collapse of the load can be connected at any position. Wearing and releasing work is also simplified.
[0029]
With these overall configurations, the elasticity of the belt is much higher than that of the load collapse prevention belt made of only non-stretchable members, and the length adjustment and the adjustment of the tightening strength can be performed satisfactorily. It is possible to do. Also, when pulling one end of the belt to adjust the tightening, even if the amount of luggage is small, the end of the belt will not be left, and 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 made of only an elastic material, the fastening strength is remarkably excellent, and extremely stable and strong winding can be secured. Further, compared to the short rubber provided partially 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.
[0030]
Above all, simply select and connect the ratio of the stretchable part to the non-stretchable part according to the type, weight and other characteristics of the luggage, and drop the luggage during transportation or storage etc. This makes it possible to form a load collapse prevention belt that can be extremely appropriately and effectively prevented.
[0031]
BEST MODE FOR CARRYING OUT THE INVENTION
The present invention will be described with reference to the drawings and reference numerals shown in the embodiments.
(Embodiment 1) FIG. 1 shows a first embodiment in which the load collapse prevention belt 100 of the present invention is applied to fix a load.
[0032]
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-shaped 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 load to be wound.
[0033]
The elastic portion 2 is generally made of a strip-like elastic woven fabric made of chemical fibers in consideration of convenience in manufacturing 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 (see FIGS. 3). In the present embodiment, for the convenience of the manufacturing operation, one elastic member is used for substantially the entirety of the belt 100 for preventing the collapse of the load. However, as described later, since a non-elastic member is overlapped and sewn on one end side (the left end side in FIG. 2), there is no elasticity in that part, and a non-elastic part 3 is formed. Only the remaining other end side portion (right end side in FIG. 2) following this constitutes the elastic portion 2.
[0034]
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. Therefore, the fastening by the elastic portion 2 is applied to the entirety of the belt 100 for preventing collapse of the load. It works with an appropriate strength 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 located below and on the upper surface of the baggage are formed as elastic portions 2. The entire length of the elastic portion 2 is longer than that of the elastic portion 2 in the unstretched state, that is, the retracted state shown in FIGS.
[0035]
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 addition, 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, but it is formed only at a part thereof or at a plurality of places at appropriate intervals, for example, near one end or in addition to the center part. You may.
[0036]
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.
[0037]
The non-stretchable portion 3 fixes the load more firmly. 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 heavy loads. 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 baggage, is easy to tighten, and is convenient to handle. .
[0038]
Further, a female fastener G facing the male fastener F is sewn on the right end side of the load collapse prevention belt 100, that is, on the upper surface on the right end side of the elastic portion 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 work of engaging and releasing the surface fasteners F and G with each other. 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.
[0039]
The length of the hook-and-loop fastener G is set to 15 cm in the present embodiment, but is appropriately determined so that the fastening is not inadvertently released when the baggage is fastened. The longer the length, the stronger the connection.
[0040]
A handle 4 projects and is fixed to the right end of the load-collapsing prevention belt 100 to facilitate the winding operation, while the left end has a work for winding and tightening the load-collapsing prevention belt 100. For convenience, a metal through ring as the locking member 1 is connected and fixed. Note that the shape and material of the locking member 1 are not limited to those shown in the drawings, and may be, for example, 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
( Reference Example) FIGS. 6 and 7 show a reference example of the load collapse prevention belt 100. FIG . The difference from the first and second embodiments is that the elastic part 2 and the non-elastic part 3 are sewn and integrated only at the edges of the respective materials, and the hook-and-loop fastener F is different from the elastic part. 2, and is not provided on the non-stretchable portion 3.
[0041]
Finally, a procedure for wrapping and fixing the load collapse prevention belt 100 around the load will be described with reference to FIG. 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 tightening degree, the male fastener provided on the stretchable portion 2 or the non-stretchable portion 3 is provided. The female 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 invention's effect】
The belt for preventing collapse of a load of the present invention has a locking member at one end in the length direction, an elastic portion having a male or female surface fastener, and a surface fastener facing the male or female surface fastener. Since the provided non-stretchable part is separated and continuous at each end side, it is used at the time of transporting and storing luggage, it has elasticity as a whole and has length adjustment, tightening strength The adjustment can be performed well.
[0043]
Further, the tightening strength of the belt is significantly superior to that of the load collapse prevention belt made of only an elastic material, and extremely stable and strong winding can be secured.
[0044]
Further, unlike a conventional belt in which a rubber portion is connected and arranged at the belt intermediate portion, winding and loosening can be easily performed only by checking an elastic portion provided at a fixed length from the end.
[0045]
Therefore, for example, even a large or heavy luggage during transportation or storage can be firmly fixed, and an excellent effect of effectively preventing the luggage from falling down can be achieved.
