Description

Binding tool

Technical Field

The present invention relates to a binding tool as a cargo fastening tool for fixing an article when the article as a cargo is transported or stored.

Background

Conventionally, when transporting or storing an article as a cargo, a binding tool is used to fix the article to a pallet for loading and unloading. For example, patent document 1 listed below discloses a cargo fastening belt in which a string body that binds a cargo placed on a pallet from three sides is formed of a belt-like belt.

Patent document 1: japanese patent laid-open publication No. 2015-67293

However, in the cargo fastening tape described in patent document 1, if the thickness of the tape is increased in order to increase the tensile strength at the time of fastening the cargo, the flexibility of the tape is impaired, and it becomes difficult to deform the tape along the uneven shape of the cargo, and it becomes difficult to stably fix the cargo having complicated uneven shapes, particularly, recessed portions formed by recesses, dents, or inner corners.

Disclosure of Invention

The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a binding tool as a cargo fastening tool capable of stably fixing a cargo.

In order to achieve the above object, the present invention includes: a first cargo fastener formed in a string shape extending in a long-line manner and having a hook at one end; a length adjusting tool for adjusting the length of the one end side of the first cargo fastener by holding the other end side at an arbitrary position; and a second cargo fastener formed in a string shape extending in a long line toward a side opposite to the first cargo fastener in the length adjustment tool and having a hook at a distal end portion thereof, wherein at least one of the first cargo fastener and the second cargo fastener is formed in a hollow tubular shape having a cross-sectional shape that is freely deformable and that can be disposed along a recess or a gap formed in a surface of the cargo to be bound.

According to the feature of the present invention thus constituted, at least one of the first cargo fastener and the second cargo fastener hooked on the cargo is formed in the hollow tubular shape having a cross-sectional shape that can be freely deformed and that can be arranged along the recess or the gap formed in the surface of the cargo to be bound, and therefore, even when the thickness of the strap is made thicker, as compared with the case where these cargo fasteners are formed of one strip-shaped strap, it is possible to suppress a decrease in flexibility for deformation and to increase the tensile strength, thereby enabling stable fixing of the cargo. In addition, in the binding tool according to the present invention, as compared with the case where the first cargo fastener and/or the second cargo fastener is formed of one strip-shaped band, the hollow tubular shape can maintain the tensile strength, and the width of the cargo fastener is halved, so that the binding tool can be flexibly deformed along the fine and complicated irregularities (particularly, a recess formed by a recess, a dent, or an inner corner) in the cargo or can be easily passed through the clearance, and can stably bind cargo in a wide range of shapes. Further, the binding tool according to the present invention can be flexibly deformed along or easily passed through the fine irregularities or gaps in the load, even when compared with the case where each of the load fastening bodies is formed of a rope or the like having a solid cross-sectional shape, and can stably fix the load having the fine and complicated irregularities or gaps. Further, since the recess is a depressed or recessed portion, it is naturally not strictly distinguishable from the gap.

In addition, according to another aspect of the present invention, in the binding tool, the first cargo fastener and/or the second cargo fastener, which are formed in a hollow tubular shape, are/is formed of woven fabric.

According to another feature of the present invention configured as described above, since the first cargo fastener and/or the second cargo fastener formed in a hollow tubular shape are/is formed of woven fabric, as compared with a case where these cargo fasteners are formed of knitted fabric formed by knitting fibers, elongation of each cargo fastener at the time of binding can be prevented, the binding force can be maintained for a long period of time, and damage due to unraveling of fibers, hooking, or the like can also be prevented. In addition, the first cargo fastener and/or the second cargo fastener is formed of a woven or knitted fabric, and thus drainage and quick-drying properties can be ensured when the first cargo fastener and/or the second cargo fastener are wet.

In the binding tool, the first cargo fastener is formed of a band extending in a band shape, and the second cargo fastener is formed in a hollow tubular shape.

According to another feature of the present invention configured as described above, since the first cargo fastener whose length is adjusted while being held by the length adjustment tool is configured by the strap in the binding tool, the length adjustment tool can be easily simplified in structure and made lighter in weight, and the length adjustment work by the length adjustment tool can be easily performed, as compared with a case where the first cargo fastener is formed in a hollow shape.

In the binding tool, the length adjustment tool may include an annular insertion ring through which the second cargo fastener is inserted, and the second cargo fastener may include hooks at both ends thereof.

According to another feature of the present invention configured as described above, since the length adjustment tool has the annular insertion ring through which the second cargo fastener passes and the hook is provided at each of the two end portions of the second cargo fastener, the cargo can be fixed at 3 points, and the cargo having a relatively uniform shape such as a cube or a rectangular parallelepiped can be stably fixed even to a cargo made of a special shape having a strong unevenness. In addition, the binding tool according to the present invention can adjust the lengths of the insertion ring and the both end portions of the second cargo fastening body via the insertion ring, and thus can fix cargoes having a wide range of sizes and shapes.

In the binding tool, the first cargo fastener and/or the second cargo fastener formed in a hollow tubular shape may include a core member formed in a fiber shape and freely bendable in a state of being freely movable in a direction orthogonal to the axial direction in the internal space.

According to another feature of the present invention configured as described above, the binding tool includes the first cargo fastener and/or the second cargo fastener, which are formed in the hollow tubular shape, and the flexible core material formed in the linear or fiber shape, which is freely movable in the thickness direction orthogonal to the axial direction, in other words, freely bendable with a spatial margin in the thickness direction, in the internal space, and therefore, the flexibility with respect to deformation such as bending can be maintained, the tensile strength can be further improved, and the cargo can be stably fixed.

In the binding tool, the core material is made of at least one of a shape memory alloy, a shape memory polymer, and a shape memory fiber.

According to another feature of the present invention configured as described above, since the binding tool is configured such that the core material is made of at least one of a shape memory alloy, a shape memory polymer, and a shape memory fiber, the binding tool can be easily deformed into a shape when binding a cargo or a shape when storing a cargo without binding, and workability can be improved. The shape memory alloy and the shape memory polymer are alloy materials or resin materials having a property of returning to the original shape before deformation even when deformed at a temperature or lower by heating to the temperature or higher. The shape memory fiber is processed so that, even if deformation such as folding or shrinking occurs, the shape memory fiber is restored to the original shape before the deformation by an operation such as drying after being placed in water.

In the binding tool, the first cargo fastener and/or the second cargo fastener formed in a hollow tubular shape may be formed in a hollow space in which no core material or the like is present in the internal space.

According to another feature of the present invention configured as described above, since the first cargo fastener body and/or the second cargo fastener body formed in the hollow tubular shape is formed as a hollow space in which any object such as a core material is not present in the internal space, the binding tool can be flexibly deformed along or easily passed through the fine irregularities or gaps in the cargo, and the cargo having the fine and complicated irregularities (particularly, recesses formed by recesses, dents, or inner corners) or gaps can be stably fixed. In the binding tool according to the present invention, the core material does not locally press the inside of the first cargo fastener and/or the second cargo fastener strongly when the cargo is bound, and the upper side cloth is in contact with the lower side cloth, as compared with the case where the core material is provided in the internal space of the first cargo fastener and/or the second cargo fastener.

In the binding tool, the first cargo fastener and/or the second cargo fastener, which are formed in a hollow tubular shape, are formed in a tubular shape having a curved surface that is smooth in the circumferential direction and has no curved portion or sewn portion on the outer peripheral portion.

According to another feature of the present invention configured as described above, in the binding tool, the first cargo fastener body and/or the second cargo fastener body formed in the hollow tubular shape is formed in the tubular shape having a smoothly curved surface without a curved portion or a sewn portion on the outer peripheral portion thereof, and therefore, the outer peripheral portion can be smoothly inserted into the gap formed on the surface of the cargo while being smoothly rotated like a crawler belt in the circumferential direction.

Detailed Description

Hereinafter, an embodiment of a binding tool according to the present invention will be described with reference to the drawings. Fig. 1 is a plan view schematically showing an appearance structure of a binding tool 100 according to the present invention. Fig. 2 is a perspective view showing a use state in which the cargo WK is fixed to the pallet 90 by using the binding tool 100 shown in fig. 1. The binding tool 100 is a tool for loading and unloading, which binds and fixes an article (for example, an engine, a transmission, or the like) placed on the pallet 90 for loading and unloading as a cargo WK to the pallet 90.

(Structure of binding tool 100)

The binding tool 100 is mainly provided with a first cargo fastener 101, a length adjustment tool 104, and a second cargo fastener 106. The first cargo fastener 101 is formed in a rope-like shape extending in a long line, and is used to adjust the length of the entire binding tool 100, and to fix the cargo WK to the cargo-handling pallet 90 in cooperation with the length adjustment tool 104 and the second cargo fastener 106.

In the present embodiment, the first cargo fastener 101 is formed of a resin material (e.g., nylon, polypropylene, or the like) in the form of a wide band having excellent tensile strength. In this case, the first cargo fastener 101 is formed to have a length sufficiently long for the assumed cargo WK of the standard size in order to cope with the cargo WK of various shapes and sizes. The first cargo fastener 101 is fitted with a clasp 102 at one end and the other end is constituted by a free end and held by a length adjustment tool 104. In addition, a protective sleeve 103 is provided between these one and the other end in the first cargo fastener 101.

As shown in fig. 3 (a) and (B), the hook 102 is a metal member for detachably hooking the one end portion of the first cargo fastener 101 to the hooking portion 92 of the pallet 90, and is mainly composed of a hook body 102a, a door body 102B, and a spring 102 c.

The hook body 102a is a portion connected to the one end of the first cargo fastener 101, and is a portion hooked to the hook portion 92, and is formed by bending a flat plate into a substantially J-shape. The door 102b is a metal bar that prevents the hook portion 92 hooked on the inside of the hook body 102a from coming off the hook body 102a and that elastically protrudes from the flat plate portion of the hook body 102a toward the distal end portion of the hook body 102 a. The spring 102c is a coil spring that elastically presses the door body 102b against the front end portion of the clasp body 102 a. In fig. 3, the relative movement direction of the hook portion 92 with respect to the hook 102 and the movement direction of the door body 102b are indicated by broken arrows.

The protective sleeve 103 is a member for preventing damage to the first cargo fastener 101 to which the cargo WK is bound, and is formed in a cylindrical shape covering an outer peripheral portion of a range of a part of the first cargo fastener 101 extending in a long length direction. In this case, the protective sleeve 103 is formed to have an inner diameter that is freely movable on the first cargo fastener 101. In the present embodiment, the protective sleeve 103 is formed by forming a sheet made of resin (e.g., polyvinyl chloride) into a cylindrical shape.

The length adjustment tool 104 is a tool for adjusting the length of the entire binding tool 100 by adjusting the length of the first cargo fastener 101, and for connecting the first cargo fastener 101 and the second cargo fastener 106 to each other, and is configured by a stopper (so-called buckle) that allows the operator to fix the first cargo fastener 101 extending in a long line at an arbitrary position. In the present embodiment, the length adjustment tool 104 is formed of a so-called snap fastener that fixes the first cargo fastener 101 by pressing the knurled pressing piece against the first cargo fastener 101 inserted through the length adjustment tool 104 by the elastic force of the torsion coil spring.

That is, the length adjustment tool 104 holds the first cargo fastener 101 so as to be able to be drawn in and out, and couples the second cargo fastener 106 in a state in which the length cannot be adjusted. The length adjusting tool 104 may be a stopper that allows the operator to adjust the length of the first cargo fastener 101 extending from the length adjusting tool 104 to any length, and may be a buckle other than a snap buckle, such as a ratchet buckle or an eccentric buckle, or a buckle that does not use the elastic force of a spring, such as a cam buckle or a ladder buckle. The length adjustment tool 104 is provided with a cargo protector 105.

The load protector 105 is a member for preventing the length adjustment tool 104 from being damaged by contact with the load WK, and is formed in a size and shape so as to cover the surface of the length adjustment tool 104 on the load WK side. In the present embodiment, the cargo protector 105 is made of a flexible sheet-like material (for example, the same material as the first cargo fastener 101) that can be bent and deformed by a person. In this case, the cargo protector 105 is attached to the lower surface of the length adjustment tool 104 by sewing, with 2 sheets being arranged adjacent to each other so as to protrude in the length direction and the width direction with respect to the length adjustment tool 104.

The second cargo fastener 106 is used to fix the cargo WK to the cargo receiving plate 90 in cooperation with the first cargo fastener 101 and the length adjustment tool 104, and the second cargo fastener 106 is formed in a rope-like shape extending in a long line. More specifically, as shown in fig. 4, the second cargo fastener 106 is formed in a tubular shape in which a resin fiber (for example, nylon, polypropylene, or the like) is woven into a hollow cylindrical shape. Thus, the second cargo fastener 106 is configured to be freely bent in a direction orthogonal to the axial direction at an arbitrary position and to be freely deformed in cross-sectional shape.

In this case, the second cargo fastening body 106 is formed to have a thickness and flexibility along or into the irregularities or gaps formed at the bound portion of the cargo WK. In this case, the second cargo fastener 106 has curved portions 106a curved in the longitudinal direction at two positions on opposite sides of the outer peripheral portion in the circumferential direction, and has an elliptical or flat cross-sectional shape flattened in the vertical direction in the figure. Here, the curved portion 106a may be formed as a seam in addition to a crease (fold) for folding the second cargo fastener 106. The second cargo fastener 106 has one end portion coupled to the length adjustment tool 104, and a hook 107 provided at a distal end portion, which is the other end portion.

The hook 107 is a metal member for detachably hooking the other end of the second cargo fastener 106 to the hooking portion 92 of the pallet 90, and is configured in the same manner as the hook 102. That is, the hook 107 includes a hook body 107a, a door 107b, and a spring 107c, which are similar to the hook body 102a, the door 102b, and the spring 102 c. In fig. 1, parts of the first cargo fastener 101, the protective sleeve 103, and the second cargo fastener 106 are not shown.

(action of binding tool 100)

Next, the operation of the binding tool 100 configured as described above will be described. The binding tool 100 is used to bind the load WK placed on the cargo-handling pallet 90 to the pallet 90 (see fig. 2). In this case, the pallet 90 is a flat plate-like body having a square shape in plan view and a size that can be placed on the load WK. A fork insertion hole 91 into which a claw of a forklift is inserted is formed in a penetrated state in 1 set of side surfaces constituted by two side surfaces facing each other out of four side surfaces of the pallet 90.

Further, of the four side surfaces of the pallet 90, the other 1 group of side surfaces, which are constituted by the remaining two side surfaces different from the above-mentioned 1 group of side surfaces and opposed to each other, are provided with hook portions 92 for hooking the

hooks

102 and 107 of the binding tool 100, respectively, in a protruding state. In this case, the hook portion 92 is formed of a round bar having an outer diameter received in each inner side of the

hooks

102 and 107 of the binding tool 100, and is formed to extend in the longitudinal direction of each side surface. Fig. 2 shows only one of the hook portions 92 formed on the two side surfaces facing each other (the front side in the figure).

The worker who binds the cargo WK to the pallet 90 first places the cargo WK on the pallet 90, and then prepares the binding tool 100 and attaches the cargo WK. Specifically, after the operator hooks the hook 102 of the first cargo fastener 101 to the hook 92 of the pallet 90, the operator places the first cargo fastener 101, the length adjustment tool 104, and the second cargo fastener 106 on the cargo WK, and hooks the hook 107 of the second cargo fastener 106 to the hook 92 on the opposite side of the hook 92 where the hook 102 is hooked.

Next, the worker ties the cargo WK to the pallet 90 using the binding tool 100. Specifically, the operator pulls the free end side of the first cargo fastener 101, thereby changing the position of the first cargo fastener 101 fixed by the length adjustment tool 104, and shortening the length of the first cargo fastener 101 extending from the length adjustment tool 104. In fastening the first cargo fastener 101, the worker appropriately adjusts the position of the second cargo fastener 106 to be placed on the cargo WK.

In this case, the worker can arrange the second cargo fastening member 106 along the irregularities or gaps formed on the surface of the cargo WK by flattening and deforming the outer shape of the second cargo fastening member 106. Specifically, since the second cargo fastener 106 is formed in a hollow cylindrical shape, as shown in fig. 5, the outer shape of the second cargo fastener 106 can be deformed flatly in the vertical direction with respect to the gap S1 extending in the vertical direction, that is, the vertical direction, and pass therethrough. In addition, as shown in figure 6, the second cargo fastener 106 is able to pass the outer shape of the second cargo fastener 106 flat in the transverse direction with respect to the gap S2 extending in the transverse direction orthogonal to the longitudinal direction.

In this case, the operator can insert the second cargo fastener 106 into the narrow gap by inserting the outer peripheral portion of the second cargo fastener 106 while rotating in the circumferential direction like a crawler. As shown in fig. 7, the second cargo fastener 106 can be closely attached to the recess O along the recess O by bending the outer shape of the second cargo fastener 106 at right angles in the width direction with respect to the recess O formed by the inner corner which is the corner recessed inward. The second cargo fastener 106 can be bound by flattening the outward convex corner K to a flat shape, thereby enlarging the contact area.

In this way, even if the gaps S1, S2 and the recess O having different shapes are formed adjacently, the second cargo fastener 106 is not forced to be deformed excessively, but passes through the gaps S1, S2 and the recess O through natural deformation. That is, the second cargo fastener 106 can be disposed along the irregularities (particularly, recesses formed by recesses, dents, or inner corners) or gaps formed on the surface of the cargo WK. In this case, since the bent portion 106a is formed in the second cargo fastener 106, the worker can easily find and correct the twist generated in the second cargo fastener 106.

Through these operations, the worker can tie the cargo WK to the pallet 90 using the binding tool 100. In addition, in the work of binding the load WK to the pallet 90 using the binding tool 100, the worker may hang the hook 107 of the second load fastener 106 on the hook 92 and then hang the hook 102 of the first load fastener 101 on the hook 92.

Next, the worker transports or keeps the cargo WK bound to the pallet 90 by the binding tool 100. In this case, the binding tool 100 can stably fix the cargo WK by fixing the cargo WK through the first cargo fastener 101 and the second cargo fastener 106 of the length adjustment tool 104.

Next, when the bound state by the binding tool 100 is released, the operator operates the length adjustment tool 104 to release the fixed state of the first cargo fastener 101, and after the length of the first cargo fastener 101 is increased, the

respective hooks

102 and 107 of the first cargo fastener 101 and the second cargo fastener 106 are removed from the hook portions 92, respectively. In this case, the worker can smoothly remove the second cargo fastener 106 inserted into the gaps S1 and S2 formed in the surface of the cargo WK by crushing the outer shape of the second cargo fastener 106 and deforming or rotating the crushed outer shape.

As can be understood from the above description of the operation, according to the above embodiment, the second cargo fastener 106 of the binding tool 100 hooked on the cargo WK is formed in the hollow tubular shape whose cross-sectional shape is freely deformable, and therefore, even when the thickness of the strap is made thicker than in the case where the second cargo fastener 106 is formed of one strip-shaped strap, it is possible to suppress a decrease in flexibility for deformation and increase the tensile strength, and to stably fix the cargo WK. In addition, in the binding tool 100 according to the present invention, as compared with the case where the second cargo fastener 106 is formed of one strip-shaped band, the second cargo fastener 106 is formed in a hollow tubular shape, so that the tensile strength can be maintained, and the width of the second cargo fastener 106 is halved, so that the second cargo fastener can be flexibly deformed along the fine and complicated irregularities or gaps in the cargo WK or can easily pass through the gaps, and thus the cargo WK having a wide range of shapes can be stably bound. In addition, the binding tool 100 according to the present invention can be flexibly deformed along or easily passed through the fine irregularities or gaps in the cargo WK, as compared with the case where the second cargo fastening body 106 is formed of a rope or the like having a solid cross-sectional shape, and thus the cargo WK having the fine and complicated irregularities or gaps can be stably fixed.

In carrying out the present invention, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the object of the present invention. In the description of each modification, the same components as those of the above-described embodiment are denoted by the same reference numerals in the drawings to be referred to, and overlapping description thereof will be omitted as appropriate.

For example, in the above embodiment, the binding tool 100 is configured by forming the second cargo fastener 106 into a hollow tubular shape. However, the binding tool 100 may be configured by forming the first cargo fastener 101 into a hollow tubular shape instead of or in addition to the second cargo fastener 106. Accordingly, the binding tool 100 can be flexibly deformed or easily passed along the fine irregularities or gaps in the cargo WK, and thus the cargo WK having the fine and complicated irregularities or gaps can be stably fixed. Further, in the binding tool 100, compared to the case where the core member (see fig. 8 and 9) is provided in the internal space of the second cargo fastener 106, when the cargo WK is bound, the core member does not locally press the inside of the second cargo fastener 106 strongly, and the upper cloth and the lower cloth of the second cargo fastener 106 contact each other, whereby deterioration of the second cargo fastener 106 can be suppressed.

In the above embodiment, the second cargo fastener 106 is formed of a woven fabric woven from resin fibers. However, the second cargo fastener 106 may be formed of fibers or wires other than resin, such as natural fibers, carbon fibers, metal fibers or wires, or may be formed of a material other than woven fabric, such as a knitted fabric formed by weaving fibers.

In the above embodiment, the second cargo fastener 106 is configured such that the bent portions 106a are formed at two positions on the outer peripheral portion along the longitudinal direction. However, the second cargo fastener 106 is configured such that the bent portion 106a is formed at least one position of the outer peripheral portion, whereby the twist of the second cargo fastener 106 can be easily confirmed. It is needless to say that the second cargo fastener 106 may be configured without the bent portion 106a, the sewn portion, or the like. That is, the second cargo fastener 106 may be formed in a cylindrical shape having a curved surface smooth in the circumferential direction without having the curved portion 106a in the outer peripheral portion. Accordingly, the second cargo fastener 106 can be smoothly inserted into the gaps S1 and S2 while the outer peripheral portion is smoothly rotated in the circumferential direction like a crawler.

In the above embodiment, the second cargo fastener 106 is formed of an empty space in which nothing is disposed in the internal space. However, the second cargo fastener 106 may be configured to have a flexible core member 110 formed in a linear or fibrous shape that is freely bendable in a state in which the core member is freely movable in a thickness direction perpendicular to the axial direction, in other words, in a state in which there is a space in the thickness direction. In this case, the core member 110 may be formed of one wire or fiber as shown in fig. 8, but may be formed of a bundle of a plurality of fibers as shown in fig. 9.

In the case where the core 110 is made of a bundle of a plurality of fibers, the fibers constituting the bundle may be made of twisted threads twisted with each other, but may be arranged so as to extend independently and in parallel without being twisted with each other. Accordingly, the binding tool 100 can easily move the core member 110 in the internal space of the second cargo fastener 106, and can further improve the tensile strength while maintaining the flexibility against deformation such as bending, thereby stably fixing the cargo WK. In addition, in the binding tool 100, when the bent portion 106a is formed in the second cargo fastener 106, the core member 110 made of a plurality of fibers is formed flat, so that the gaps S1 and S2 can be easily inserted. As the fibers constituting the core material 110, resin fibers, carbon fibers, or glass fibers can be used in addition to natural fibers. The core member 110 may be made of a wire material thicker than the fiber, for example, a wire material made of metal such as a wire.

The core 110 may be formed of at least one of a wire made of a shape memory alloy, a wire made of a shape memory polymer, and a shape memory fiber. Accordingly, the binding tool 100 can be easily deformed into a shape when the cargo WK is bound or a shape when the cargo WK is not bound, and the workability can be improved. The shape memory alloy and the shape memory polymer are alloy materials or resin materials having a property of returning to the original shape before deformation even when deformed at a temperature or lower by heating to the temperature or higher. The shape memory fiber is processed so that, even if deformation such as folding or shrinking occurs, the shape memory fiber is restored to the original shape before the deformation by an operation such as drying after being placed in water.

In the above embodiment, the binding tool 100 is configured such that one end portion of the second cargo fastener 106 is coupled to the length adjustment tool 104, and the other end portion thereof is provided with the hook 107. That is, the binding tool 100 is configured in a single linear shape so as to be bound to the cargo WK at two places. However, the binding tool 100 may be formed in a three-forked shape so as to be bound at three positions with respect to the cargo WK.

Specifically, as shown in fig. 10, the binding tool 100 may be configured such that the insertion ring 121 is provided through the coupling body 120 on the opposite side of the length adjustment tool 104 from the side holding the first cargo fastener 101, and the hooks 107 are provided on both end portions of the second cargo fastener 106. In this case, the coupling member 120 is a member for coupling the length adjustment tool 104 and the second cargo fastener 106 to each other, and is made of the same material as the first cargo fastener 101. Accordingly, the length adjustment tool 104 and the insertion ring 121 are coupled to each other so as to be displaceable and changeable in direction by deformation of the coupling body 120.

The insertion ring 121 is a member for allowing the second cargo fastener 106 to pass through so as to be free, and is coupled to the length adjustment tool 104, and is formed by forming a round rod made of metal into a circular ring shape. In this case, the insertion ring 121 is formed in a ring shape having an inner diameter sufficiently larger than the width of the second cargo fastening body 106. Thereby, the second cargo fastener 106 is formed to be bifurcated via the insert-through ring 121. That is, the binding tool 100 is formed in a three-pronged shape by the first cargo fastener 101 and the second cargo fastener 106. In this case, the cargo protector 105 is formed to cover the insertion ring 121 with respect to the cargo WK.

When using the binding tool 100 configured as described above, as shown in fig. 11, the operator engages the first cargo fastener 101 with the hook portion 92 of the pallet 90 and engages the two hooks 107 of the second cargo fastener 106 with the hook portion 92 on the opposite side of the first cargo fastener 101, and then operates the length adjustment tool 104 to bind the cargo. According to the binding tool 100 configured as described above, the cargo WK can be fixed at 3 points, and thus the cargo WK having a relatively uniform shape such as a cube or a rectangular parallelepiped can be stably fixed even if the cargo WK is formed of a irregularly shaped object excited by irregularities. In addition, the binding tool 100 can fix the cargo WK having a wide size and shape by adjusting the lengths of the insertion ring 121 and the both end portions of the second cargo fastening body 106 via the insertion ring 121.

The insertion ring 121 may be provided directly to the length adjustment tool 104 without the coupling member 120. The insertion ring 121 may be made of a material other than a metal material (e.g., a resin material), or may be formed in a ring shape other than a circular shape (e.g., a square shape).

In the above embodiment, the binding tool 100 is configured to include the protective sleeve 103 and the cargo protector 105, respectively. However, the binding tool 100 may be configured without the protective sleeve 103 and the cargo protector 105. In addition, the binding tool 100 may also be provided with a protective sleeve 103 on the second cargo fastener 106.

In the above embodiment, the binding tool 100 is configured to include the

door bodies

102b and 107b and the

springs

102c and 107c in the

clasps

102 and 107, respectively. However, the

hooks

102 and 107 are not necessarily limited to the above-described embodiment as long as they are metal fittings that can be hooked at least to the hook portion 92. That is, the

hooks

102 and 107 can be configured without the

door bodies

102b and 107b and the

springs

102c and 107c, respectively. The

clasps

102, 107 are formed of so-called flat hooks in which clasp

bodies

102a, 107a are formed by bending flat plates. However, the

clasps

102 and 107 may be configured by other than a flat hook, for example, a key hook (also referred to as a narrow hook), a triangular ring hook, an ナスカン (egg plant Kang) hook, a rotating hook, a chain hook, a snap hook, or the like.

In addition, in the above embodiment, the binding tool 100 fixes the cargo WK to the pallet 90. However, the binding tool 100 is not necessarily limited to the above embodiment as long as it is used when fixing the cargo WK for transportation and storage. That is, the binding tool 100 can fix the cargo WK to, for example, a carrier of a vehicle or a ground surface provided with an anchor bolt, in addition to the pallet 90.
