[Problems to be solved by the invention]
When using a band-shaped load collapse prevention band described in Patent Documents 1 to 4 (hereinafter sometimes simply referred to as a “band”), a ring-shaped load collapse prevention band is wound around the stacked load, In order to secure the stability of the load, it is preferable to pull the handle of the bag and fix the stacked load in a state of being tightened with an appropriate force without causing wrinkles or slack in the band.
[0005]
However, a considerable amount of force is required to sufficiently pull both ends of the belt-shaped load collapse prevention band, so it is not easy when working alone. In addition, since each of the handle rings as shown in FIG. 6 is attached to one point of the band end, it is difficult to pull the entire band evenly even if one handle ring is pulled. In particular, even if the length is the same, the band becomes heavier when the width of the band becomes wider. In addition, a band made of a flexible sheet material is more likely to be wrinkled or loosened as it is wider, making it more difficult to pull evenly.
[0006]
From the viewpoint of stably holding the load, it can be said that it is most preferable that the load is sufficiently tightened using a wide band having a large area covering the load. In addition, even when it is necessary to wrap a plurality of bands in a narrow band, there may be one band in a wide band, and a wide band is preferable from the viewpoint of work load.
[0007]
In view of the above situation, the present invention is a load collapse prevention band for a stacked load loaded on a cart, a pallet or the like, and can stably fix the entire stacked load with an even holding force, In addition, an object of the present invention is to provide a load collapse prevention band that can be easily wound and fixed even with a wide band and can be pulled evenly without causing wrinkles or slack in the band.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the embodiments shown in the drawings.
1-3 is a figure which shows one Embodiment of the load collapse prevention band 10 by this invention. 1A is a front view, FIG. 1B is a back view, FIG. 1C is a front view, FIG. 2A is a left side view, FIG. 2B is a right side view, and FIG. (A), (B) and (C) are enlarged views in the X, Y and Z circles in FIG. 1 (C), respectively. In addition, although the load collapse prevention band 10 by this invention is normally manufactured by sewing each structural member, the seam is abbreviate | omitted in the figure. The same applies to other embodiments below. In addition to stitching, it can also be manufactured using other means such as thermocompression bonding and adhesion.
[0014]
As shown in the front view of FIG. 1 (A), the load collapse prevention band 10 has a winding portion 11 for winding around a stacked load. The winding portion 11 is a flexible band-shaped member made of a cloth such as polyester having a certain width. In addition, the length of the winding part 11 is set to a length suitable for the peripheral length of the stacked luggage to be fixed.
[0015]
In the following description, both sides in the longitudinal direction of the belt-shaped member or the vicinity thereof are referred to as “end portions”, and both sides in the width direction or the vicinity thereof are referred to as “edge portions”.
[0016]
A first handle rod 15 is attached along the first end portion (the right end portion in FIG. 1) of the winding portion 11. The first handle rod 15 is a rigid rod-like member having a length equivalent to the width of the winding portion 11. Preferably, it is made of FRP (fiber reinforced plastic), but may be made of metal. Here, the “equivalent length” does not have to be exactly equal, but may extend over almost the entire bandwidth (the same applies to other rods described later). Moreover, the strength with respect to a bending deformation is required and it is preferable that it is lightweight.
[0017]
As shown in FIG. 1B, the first end portion of the winding portion 11 is folded from the front surface 11a to the back surface 11b to form a folded portion 11c. Both ends of the first handle rod 15 are wound around the folded portion 11c. The first handle rod 15 is attached to the winding portion 11 by sewing the periphery of the folded portion 11c with both ends of the first handle rod 15 being wound. In addition, the attachment method of the 1st handle rod 15 is not restricted to this method. For example, instead of folding, both ends of the handle rod 15 may be wrapped with another sheet member and attached to the first end of the winding portion 11.
[0018]
Furthermore, a rectangular recess 11d is formed in the vicinity of the center of the first end of the winding portion 11. On both sides of the notch recess 11d, there are folded portions 11c in which both ends of the first handle rod 15 are fixed. As a result, a through hole 19 surrounded by the notch recess 11 d and the central portion of the first handle rod 15 is formed. Since the band fixing portion 12 to be described later is passed through the through hole 19 when the band 10 is attached, the length (the length in the width direction of the winding portion 11) is set to the band fixing portion 12 to be described later. It must be longer than the width of. In addition, it becomes easy for an operator to hold | grip the 1st handle rod 15 because this through-hole 19 exists.
[0019]
As shown in FIGS. 1A and 1B, the support rod 16 is attached along the second end portion (the left end portion in FIG. 1) of the winding portion 11. The support rod 16 may be the same shape and material as the first handle rod 15 described above. As shown in FIG. 1B, the second end portion of the winding portion 11 is folded back from the front surface to the back surface to form a folded portion 11e. Since the support rod 16 is wound around the folded portion 11e, it does not appear in appearance. The support rod 16 is attached to the winding portion 11 by sewing the periphery of the folded portion 11e in a state where the support rod 16 is wound. In addition, the attachment method of the support rod 16 is not restricted to this method. For example, instead of folding, the support rod 16 may be covered with another sheet member and attached to the second end of the winding portion 11.
[0020]
As shown in the rear view of FIG. 1 (B), at the central portion of the second end of the winding portion 11, one end portion of the band fixing portion 12 (hereinafter referred to as a band-shaped member narrower than the winding portion 11) , Referred to as “attachment end”), and further extends in the longitudinal direction. In FIG. 1B, the back surface 12b of the band fixing portion 12 is exposed. The band fixing portion 12 is formed from the same flexible material as the winding portion 11, for example, a polyester fabric. The width of the band fixing portion 12 is preferably about half of the width of the winding portion 11, but is not limited thereto.
[0021]
Preferably, as shown in FIGS. 1 (A) and 1 (B), the second end portion of the winding portion 11 and each of both width direction edge portions on the attachment end portion side of the band fixing portion 12 are connected. A pair of triangular corner portions 11f and 11f are provided. If the corner portion of the winding portion 11 remains at a right angle, the band 10 may be bent and caught during the attaching operation of the band 10, or may float or sag after fixing. Accordingly, the handling and stability of the band 10 are improved by providing such a triangular corner portion 11f. Further, it is reinforced in terms of strength, and is preferable in terms of appearance.
[0022]
Further, as shown in FIGS. 1A and 1B, an end portion (hereinafter simply referred to as “end portion”) opposite to the attachment end portion of the band fixing portion 12 extends along this end portion. A second handle rod 17 is attached. The second handle rod 17 is made of the same material as the first handle rod 15 and the support rod 16 described above, but the length is shorter than these, and the length is equal to the width of the band fixing portion 12.
[0023]
As shown in FIG. 1 (B), the folded portion 12c is formed by folding the end of the band fixing portion 12 from the front surface to the back surface. The second handle rod 17 is attached to the band fixing portion 12 by sewing the periphery of the folded portion 12c with the second handle rod 17 wound. In addition, the attachment method of the 2nd handle rod 17 is not restricted to this method. For example, instead of turning back, both ends of the handle rod 17 may be wrapped with another sheet member and attached to the end of the band fixing portion 12.
[0024]
Further, in the vicinity of the center of the end portion of the band fixing portion 12, a concave portion 12d that is cut out in a rectangular shape is formed. On both sides of the notch recess 12d, there are folded portions 12c in which both ends of the second handle rod 17 are fixed. As a result, a handle hole 20 surrounded by the notch recess 12d and the central portion of the second handle rod 17 is formed. Since the handle hole 20 is provided, the operator can easily grip the second handle rod 17.
[0025]
Further, as shown in FIG. 1 (A), a first surface fastener 13 is attached to the entire surface of the band fixing portion 12 over the entire surface. In the present embodiment, the first surface fastener 13 extends beyond the band fixing portion 12 and further onto the surface 11 a of the winding portion 11. The length of the first surface fastener 13 is appropriately set in consideration of the length of the winding portion 11 that is set appropriately for the peripheral length of the stacked cargo to be fixed.
[0026]
Further, a second surface fastener 14 is attached to the end of the band fixing portion 13 on the same surface as the one surface to which the first surface fastener 13 is attached. The first surface fastener 13 and the second surface fastener can be joined together by matching the surfaces. For example, if the first surface fastener 13 is a member with a loop of a normal surface fastener, the second surface fastener. Similarly, reference numeral 14 denotes a hook-and-loop member of a hook-and-loop fastener (which may naturally be reversed). As will be described later with reference to FIG. 4, when the band 10 is attached, the band fixing portion 13 is passed through the through-hole 19 of the winding portion 11 and folded back, so that the second surface fastener 14 of the band fixing portion 13 and the The 1 surface fastener 13 joins and the band 10 is fixed. Accordingly, the shapes and attachment positions of the first surface fastener 13 and the second surface fastener 14 are not limited to the illustrated example, and can be appropriately designed so that they can be joined to each other when the band fixing portion 13 is folded back. However, it is necessary to ensure a bonding strength that allows the band 10 to be securely fixed in a state in which the stacked cargo is properly tightened.
[0027]
In the front view of FIG. 1C, the thickness of the sheet members such as the winding portion 11 and the band fixing portion 12 is exaggerated. Thus, the three rigid rods 15, 16, and 17 are attached to the load collapse prevention band 10 of this invention in the width direction. At the positions of these rods, each band member does not bend. Therefore, these rods have a function as a frame or a skeleton for supporting the band-shaped member constituting the band, and thereby handleability is improved even for a wide band that is easily loosened.
[0028]
Although FIG. 2 is as illustrated, the thickness of the sheet member is exaggerated in the same manner as in FIG.
[0029]
As shown in each enlarged view of FIG. 3, the first handle rod 15, the support rod 16, and the second handle rod 17 are wound by the folded portions 11c and 11e of the winding portion 11 and the folded portion 12c of the band fixing portion, respectively. Both ends are wrapped and fixed.
[0030]
In one embodiment, the length of the winding part 11 is 370 cm, the width is 60 cm, the length of the band fixing part 12 is 90 cm, and the width is 30 cm. In this case, the length of the first handle rod 15 and the support rod is about 60 cm, and the length of the second handle rod 17 is about 30 cm. The length of the through hole 19 was 34 cm, and the length of the handle hole 20 was 12 cm.
[0031]
In another embodiment, the length of the winding part 11 is 360 cm, the width is 80 cm, the length of the band fixing part 12 is 90 cm, and the width is 40 cm. In this case, the length of the first handle rod 15 and the support rod is about 80 cm, and the length of the second handle rod 17 is about 40 cm. The length of the through hole 19 was 44 cm, and the length of the handle hole 20 was 12 cm.
[0032]
FIG. 4 is a diagram schematically showing a work procedure for attaching the load collapse prevention band 10 of the present invention shown in FIGS. First, as shown in FIG. 4A, the band 10 is wound around the stacked luggage 200. After winding, the first handle rod 15 is gripped by the operator's right hand 32, the second handle rod 17 is gripped by the left hand 31 and both ends of the band 10 are drawn, and both handle rods 15, 17 are pulled in the direction of the arrows. By pulling, the load 10 is tightened with the band 10 and the band 10 is free from wrinkles and slack.
[0033]
Next, as shown in FIG. 4 (B), the end of the band fixing portion 12 (second handle rod 17) is attached to the winding portion 11 as shown by the arrow while the handle rods 15 and 17 are pulled. Pass through the through hole 19. At this time, the handles 31 and 32 of both handle rods are usually changed.
[0034]
Finally, as shown in FIG. 4C, after holding the second handle rod 17 and folding the band fixing portion 12 as indicated by the arrow, the second handle rod 17 is sufficiently pulled in the opposite direction as indicated by the arrow. This tightens the stacked luggage 200. As described above, in the present invention, the entire band 10 having a wide width can be tightened by applying a force only to the end of the narrow band fixing portion 12 and pulling it, so that it is very easy to apply a force. In this way, the second surface fastener 14 and the first surface fastener 13 at the end of the band fixing portion 12 are joined and fixed in a state where the band 10 is tightened with an appropriate force.
[0035]
In addition, in the example of FIG. 4, although it fixes on one side surface of the stacked luggage 200, you may fix in a corner | angular part.
[0036]
As shown in FIG. 4, the load collapse prevention band 10 of the present invention has handle rods 15 and 17 attached to both ends thereof, so that it is easy to apply force when pulling both ends, and both handle rods 15 and 17 are attached. Since each has a length equivalent to the width of each of the winding part 11 and the fixed band part 12, a force can be applied equally to the respective band-like members.
[0037]
FIG. 5 shows another embodiment of the load collapse prevention band 10 of the present invention. In this embodiment, the winding part 11 is the same as that of the embodiment shown in FIGS. 1 to 3 except that one handle ring 18 is attached to the end of the fixed band part 12 instead of the second handle rod. Is different. The attachment work procedure is almost the same as the example shown in FIG. 4, but the fixed band portion 12 is pulled with the handle ring 18 instead of the second handle rod. This embodiment is suitable for a relatively narrow band. The handle ring 18 is inferior to the second handle rod in terms of the function of evenly exerting force and the function of supporting the fixed band part 12, but when the band 10 is narrow, the width of the fixed band part 12 is about half that width. Therefore, this is not a problem. However, also in the case of this embodiment, the handle rod 15 and the support rod 16 are attached to the first end and the second end of the winding portion 11, respectively, to support the entire band.
[0038]
In one example of the embodiment shown in FIG. 5, the length of the winding part 11 is 370 cm, the width is 40 cm, the length of the band fixing part 12 is 90 cm, and the width is 20 cm. In this case, the length of the first handle rod 15 and the support rod is about 40 cm. The length of the through hole 19 was 24 cm.
[0039]
As yet another embodiment, a partial region in the longitudinal direction of the winding portion 11 in the above two embodiments may be constituted by a cloth made of an elastic material. Thereby, the force which fastens a stacked load increases and it can hold a load more stably.
[0040]
【The invention's effect】
The load collapse prevention band 10 of the present invention has handle rods 15 and 17 attached to both ends thereof, so that it is easy to apply a force when pulling both ends. Since it is the length equivalent to the width | variety of the fixed band part 12, force can be equally applied with respect to each strip | belt-shaped member. This facilitates handling and improves workability.
[0041]
Furthermore, the end of the band fixing part 12 is passed through the through hole 19 of the first end of the winding part 11 and folded back, and the stacked luggage can be tightened. In this way, the method of folding and pulling the band-shaped band fixing portion narrower than the band main body is extremely easy to apply force, and a large tightening force can be obtained.
[0042]
Furthermore, since the handle rod 15 and the support rod 16 of the winding part 11 have a function as a support frame of the flexible winding part 11, the band 10 can be attached without causing extra wrinkles or slack. This also improves workability.
