(Structure of the load fastening belt 100)
The load fastening belt 100 is mainly composed of a length adjusting belt body 110, a bifurcated belt body 140, and a lock body 150. As shown in FIGS. 2 and 3A and 3B, the length adjusting belt body 110 enables adjustment of the entire length of the load tightening belt 100 while allowing the forked belt body 140 and the lock body. It is for fixing the cargo WK on the pallet 90 for cargo handling in cooperation with 150, and is mainly constituted by the belt 111, the protective sleeve 120 and the hook 130.

Of these, the belt 111 is a long member that is hung on the luggage WK, and is made of a resin material (for example, nylon, polypropylene, or the like) formed in a wide band shape having excellent tensile strength. The belt 111 is an insertion portion 111a having a free end to which the hook 130 is attached at one end and nothing is attached to the other end.

In this case, the insertion portion 111a, which is the other end portion of the belt 111, is the portion that is first inserted into the lock body 150, and the tip portion is formed to have an acute point. The belt 111 is formed to have a length that is sufficiently long with respect to the assumed standard size luggage WK in order to accommodate various shapes and sizes of luggage WK.

The protective sleeve 120 is a component for preventing the belt 111 from being damaged when the belt 111 binds the luggage WK, and is formed in a tubular shape that covers an outer peripheral portion of a part of the longitudinally extending belt 111 in the longitudinal direction. Has been done. In this case, the protective sleeve 120 is formed with an inner diameter of a size that allows it to move freely on the belt 111. In the present embodiment, the protective sleeve 120 is formed by forming a resin (for example, polyvinyl chloride) sheet material into a tubular shape.

As shown in FIGS. 4A to 4E, the hook 130 is a metal part for detachably hooking one end of the belt body 111 on the hooked body 92 of the pallet 90. It is mainly configured by the flat hook body 131 and the gate body 132. Among these, the flat hook main body 131 is a portion that is connected to the belt 111 and that is hooked on the to-be-engaged body 92, and is formed by bending a flat plate into a substantially J shape.

More specifically, in the flat hook main body 131, one end portion side of a base portion 131a extending in a flat plate shape is formed wide to form a long-belt-shaped belt connecting portion 131b, and the other end portion side is wide. The hooking portion 131c is formed by being bent and folded back after extending with a width narrower than the portion. In this case, the hooking portion 131c of the flat hook main body 131 bent in the folding direction is formed of an inclined surface having a tip portion separated from the base portion 131a.

The tip portion of the hook portion 131c is formed in a shape that follows the shape of the hook portion 131c side on the outer periphery of the top surface of the tip portion 133b of the gate body 132. Specifically, the tip portion of the hooking portion 131c is formed in an arc shape in which the portion where the tip portion 133b of the gate body 132 faces is recessed, and both sides thereof project in a convex shape, respectively, and in plan view as a whole. It is formed in a concave curved shape.

The gate body 132 prevents the hooked body 92 hooked inside the hooking portion 131c of the flat hook main body 131 from coming off the hooking portion 131c, and is located below the front of the hooking portion 131c. It is formed on the base 131a so as to be pushed down toward the side of the base 131a. The gate body 132 is mainly composed of a pin body 133 and a spring 134.

Of these, the pin body 133 is a metal rod body, and is provided so as to slidably penetrate the base 131a of the flat hook body 131. The pin body 133 is formed by protruding both ends of a cylindrically extending pin body 133a into a flange shape, and the tip end 133b of these ends on the hooking portion 131c side is located outside the center of the upper surface. It is composed of an inclined surface that is inclined toward the base portion 131a toward the side.

In the present embodiment, the tip portion 133b of the pin body 133 has a spherical surface. In the pin body 133, the upper surface of the tip portion 133b is lower than the upper surface of the hook portion 131c in the flat hook body 131, and the lower surface of the tip portion 133b is lower than the lower surface of the tip portion of the hook portion 131c. Is formed. The end of the pin body 133 on the side opposite to the tip 133b is formed into a flange shape by caulking to prevent the pin 131 from coming off from the base 131a.

The spring 134 is a component for elastically pushing the tip portion 133b of the pin body 133 in a direction separating from the base portion 131a, and is provided on the outer peripheral portion of the pin body 133a between the tip portion 133b and the upper surface of the base portion 131a. Has been. That is, the spring 134 is configured by a coil spring in this embodiment.

As shown in FIGS. 2 and 5A and 5B, the bifurcated belt body 140 cooperates with the length adjusting belt body 110 and the lock body 150 to load the cargo WK on the pallet 90 for cargo handling. The belt 141, the protective sleeve 120, and the hook 130 are mainly configured.

Of these, the belt 141 is a long member that is hung on the luggage WK, like the belt 111, and is formed of a resin material (for example, nylon or polypropylene) in a wide band shape having excellent tensile strength. Is configured. In this case, the belt 141 is formed in such a length that it can be hooked on a part of the load WK on the pallet 90 in a state where the hooks 130 provided at both ends of the belt 141 are hooked on the hooked members 92 of the pallet 90. ing.

The belt 141 is provided with a protective sleeve 120 for protecting the belt 141, and hooks 130 for hooking both ends of the belt 141 to the hooked body 92 are attached to both ends of the belt 141, respectively. Has been. Since the protective sleeve 120 and the hook 130 have the same structure as the protective sleeve 120 and the hook 130 in the length adjusting belt 110, the description thereof will be omitted. The two hooks 130 provided at both ends of the belt 141 are attached with their front and back surfaces reversed.

As shown in FIGS. 2 and 6A and 6B, the lock body 150 allows the length adjustment belt body 110 and the bifurcated belt body while allowing the entire length of the load fastening belt 100 to be adjusted. This is for fixing the cargo WK on the pallet 90 for cargo handling in cooperation with 140, and is mainly composed of a belt fixing member 151, a connecting belt 152, a ring body 153, and a cargo protecting body 154.

Of these, the belt fixture 151 is a fastener (a so-called buckle) that can fix the belt 111 of the length adjusting belt body 110 that is passed through the inside of the belt fixture 151 at an arbitrary position of the operator. is there. In the present embodiment, the belt fixture 151 is configured by a so-called spring buckle that fixes the belt 111 by pressing the knurled pressing piece 151a against the belt 111 by the elastic force of the torsion coil spring 151b. The belt fixing member 151 may be a fastener that can fix the belt 111 at an arbitrary position of an operator, and may be a buckle other than a spring buckle, such as a ratchet buckle or an over center buckle, or a spring buckle. A buckle that does not utilize elastic force, such as a cam buckle or a rudder buckle, may be used.

A ring body 153 is connected to one end (right side in the drawing) of the belt fixing member 151 via a connecting belt 152. The connection belt 152 is a component for connecting the belt fixing member 151 and the ring body 153, and is made of the same material as the belt 111 and the belt 141. As a result, the belt fixing member 151 and the ring body 153 are connected to each other by the deformation of the connecting belt 152 so that they can be displaced and deflected.

The ring body 153 is a part for connecting the lock body 150 by allowing the bifurcated belt body 140 to pass therethrough, and is formed by forming a metal round bar into a circular ring shape. In this case, the ring body 153 is formed in a ring shape having an inner diameter sufficiently larger than the width of the bifurcated belt body 140.

A luggage protector 154 is attached to the lower surface of the connecting belt 152. The luggage protector 154 is a component for preventing the belt fixture 151 and the ring body 153 from contacting and damaging the luggage WK, and at least the surface of the belt fixture 151 and the ring body 153 on the article WK side. It is composed of a size and a shape to cover. In the present embodiment, the luggage protector 154 is composed of a main body portion 154a and an extension portion 154b made of a material that can be bent and deformed manually (for example, the same material as the belt 111 and the belt 141).

Of these, the main body portion 154a is formed to have a length longer than both ends between the belt fixing member 151 and the ring body 153, and has a width longer than the width of the belt fixing member 151 and the ring body 153. It is formed in a rectangular shape as viewed. The main body 154a is connected to the connecting belt 152 by sewing.

On the other hand, the expansion portion 154b is formed in a rectangular shape in a plan view, and two main body portions are arranged along the longitudinal direction of the lock body 150 on the portion of the main body portion 154a where the belt fixture 151 is arranged. They are attached to 154a by stitching. Thereby, a cut 154c is formed between the two expanded portions 154b arranged adjacent to each other. Each of the extension portions 154b has such a length that the length in the width direction of the belt fixing member 151 surrounds both side surface portions of the belt fixing member 151, and then both ends of the extension portion 154b are at least in contact with each other on the upper surface of the belt fixing member 151. That is, each of them is formed to have a length capable of covering the upper surface of the belt fixing member 151.

In addition, of the two extension portions 154b arranged along the longitudinal direction of the lock body 150, the extension portion 154b on the length adjusting belt 110 side (the side opposite to the ring body 153) is the length of the belt fixing member 151. The adjustment belt 110 is formed so as to project from the same side surface as long as it can cover the side surface on the adjustment belt 110 side. That is, in the present embodiment, the lock body 150 is configured by connecting the belt fixing tool 151, the ring body 153, and the luggage protector 154 to the connecting belt 152. The load fastening belt 100 is configured by detachably connecting the length adjusting belt body 110 and the bifurcated belt body 140 to the lock body 150.

(Operation of the belt 100 for tightening the load)
Next, the operation of the load fastening belt 100 configured as described above will be described. The cargo fastening belt 100 is used for securing the cargo WK placed on the cargo handling pallet 90 to the pallet 90. In this case, the pallet 90 is a flat table formed in a rectangular shape in plan view having a size capable of mounting the luggage WK. Of the four side surfaces of the pallet 90, a pair of side surfaces composed of two side surfaces opposed to each other is formed with a fork insertion hole 91 for inserting a pawl of a forklift.

Further, of the four side surfaces of the pallet 90, the hooked bodies 92 for hooking the hooks 130 respectively project to the other pair of side surfaces that are different from the one pair of side surfaces and that are the other two side surfaces facing each other. It is provided in the open state. In this case, the hooked body 92 is composed of a round bar having an outer diameter that fits inside the hooking portion 131c of the hook 130, and is formed to extend along the longitudinal direction of each side surface. Note that FIG. 2 shows only one (front side in the drawing) of the hooked bodies 92 formed on the two side surfaces facing each other.

An operator who binds the luggage WK onto the pallet 90 first places the luggage WK on the pallet 90, and then prepares the load fastening belt 100. In this case, the operator can prepare the load tightening belt 100 in which the length adjusting belt body 110 and the bifurcated belt 140 are connected to the lock body 150 in advance. It is also possible to prepare and prepare the load-tightening belt 100 suitable for the size and shape. That is, the worker previously manufactures the length adjusting belt body 110 and the bifurcated belt body 140 having a plurality of types of lengths, respectively, and has a length suitable for the size and shape of the luggage WK during the lashing operation. The height adjusting belt body 110 and the bifurcated belt body 140 can be selected and prepared together with the lock body 150.

Next, when the worker separately prepares the length adjusting belt body 110, the forked belt body 140, and the lock body 150, the worker adjusts the length adjustment belt body 110 and the forked body with respect to the lock body 150. The belt bodies 140 are connected to each other. Specifically, the operator passes the belt 111 of the length adjusting belt body 110 through the belt fixture 151 of the lock body 150, and the belt 141 of the bifurcated belt body 140 through the ring body 153 of the lock body 150. In this case, when the worker connects the length adjusting belt 110 to the lock body 150, the worker finally needs the length of the belt 111 extending from the belt fixing member 151 to the hook 130 side to secure the luggage WK. Adjust the length to be equal to or longer than As a result, the length adjusting belt body 110 and the bifurcated belt body 140 are connected to the lock body 150, respectively, to form an integrated cargo fastening belt 100.

Next, the worker hangs the load fastening belt 100 on the pallet 90 via the load WK. Specifically, the worker hooks the two hooks 130 of the bifurcated belt 140 on the hooked members 92 of the pallet 90, respectively. More specifically, as shown in FIG. 7A, the worker presses the hooked body 92 against the tip portion 133b of the pin body 133 of the hook 130. As a result, the pin body 133 of the hook 130 slides while resisting the elastic force of the spring 134, and the tip portion 133b is displaced toward the base portion 131a side (see the broken line arrow in the figure).

In this case, in the hooked body 92, the tip portion 133b of the pin body 133 is composed of an inclined surface that inclines toward the base portion 131a from the top to the outside, so that the hook portion 131c is smoothly inserted into the hook portion 131c. Be guided to. Further, in this case, since the base portion 131a and the hook portion 131c of the hook 130 are formed in a flat plate shape, the hook 130 has a bent portion in the hooked body 92 and a hook extending from the bent portion to the side surface of the pallet 90. It is possible to prevent the mistake of accidentally hooking the hook portion 131c to a portion shorter than the width of the portion 131c.

When the hooked body 92 is located inside the hook portion 131c, the pin body 133 of the hook 130 is moved from the base portion 131a to the tip portion 133b by the elastic force of the spring 134, as shown in FIG. 7B. Since it moves away from the hook portion 131c in a direction away from the hook portion 131c, the inside of the hook portion 131c is closed by the pin body 133 (see a broken line arrow in the drawing). As a result, the hook 130 is brought into a locked state in which the to-be-engaged body 92 located inside the hook portion 131c is prevented from coming off from inside the hook portion 131c. In addition, in the present embodiment, as shown in FIGS. 1 and 7A and 7B, the hook 130 is hooked by the so-called external hook which is hung from the outside of the hooked body 92. It is also possible to hang it by a so-called inner hook that is hung from the inside of the hook body 92.

Next, the worker hooks the hook 130 of the length adjusting belt body 110 on the hooked body 92 of the pallet 90 in the same manner as the two hooks 130 of the bifurcated belt body 140. In this case, the operator has already locked the two hooks 130 of the bifurcated belt body 140 on one of the hooked bodies 92 of the pallet 90 by the gate bodies 132, so that the length adjusting belt body 110. It is possible to prevent the two hooks 130 of the bifurcated belt body 140 from coming off the hooked body 92 when the hooks 130 are hooked on the hooked body 92 of the pallet 90.

Next, the worker fastens the load WK to the pallet 90 with the load fastening belt 100. Specifically, the worker changes the position of the belt 111 fixed by the belt fixing device 151 by pulling the insertion portion 111a side, which is the free end of the belt 111 of the length adjusting belt body 110, to fix the belt. The length of the belt 111 from the tool 151 to the hook 130 of the length adjusting belt body 110 is shortened. In the process of tightening the length adjusting belt body 110, the operator adjusts the fixing position of the belt 111 by the belt fixing member 151 and the position where the belt 141 is hooked on the ring body 153 while adjusting the lock body 150 on the luggage WK. You can decide the position in.

In this case, the operator can place the lock body 150 at a position avoiding the convex portions P1 and P2 when the convex portions P1 and P2 formed of the protrusions are present on the luggage WK. In addition, since the lock body 150 has the luggage protector 154 between the belt fixture 151 and the ring body 153 and the luggage WK, the luggage WK is prevented from being damaged by the contact between the belt fixture 151 and the ring body 153. can do.

Further, in the process of tightening the length adjusting belt body 110, the worker positions the protective sleeves 120 on the belts 111 and 141 located on the corners of the luggage WK and near the belt fixture 151. When the convex portion P2 is present, the expanded portion 154b of the luggage protector 154 is arranged between the belt fixing member 151 and the convex portion P2. In this case, since the operator has the cut 154c formed in the expanded portion 154b of the luggage protector 154, in other words, since the expanded portion 154b is composed of two sheets, the worker can accurately match the shape of the convex portion P2. Can be placed in the extension 154b.

Through these operations, the worker can fasten the load WK to the pallet 90 using the load fastening belt 100. In addition, in the work of fastening the luggage WK to the pallet 90 using the load fastening belt 100, the worker hangs the hook 130 of the length adjusting belt body 111 on the hooked body 92, and then, It goes without saying that the two hooks 130 of the belt body 140 may be hung on the hooked body 92, respectively. Further, the operator can also hook the tip end portion 133b of the pin body 133 in the hook 130 on the hooked body 92 by pushing down with a finger or the like.

Next, the worker transports or stores the load WK secured on the pallet 90 by the load fastening belt 100. In this case, since the load fastening belt 100 fixes the luggage WK at three points by the length adjusting belt body 110 and the bifurcated belt body 140 via the lock body 150, the luggage WK can be stably fixed. .. Further, since the base portion 131a and the hooking portion 131c of the hook 130 are formed in a flat plate shape and the hook 130 is hooked along the longitudinal direction of the hooked portion 92, the load tightening belt 100 does not vibrate from the outside. Even when a sudden force is applied, the displacement from the hooked body 92 is prevented and the binding force can be maintained. Further, in this case, in the cargo fastening belt 100, the hooks 130 are also prevented from being disengaged from the hooked body 92 by the gate body 132.

Next, in order to release the secured state by the load fastening belt 100, the operator operates the belt fixing tool 151 in the lock body 150 to release the fixed state of the belt 111 in the length adjusting belt body 110. Then, the hooks 130 of the length adjusting belt body 110 and the bifurcated belt body 140 are removed from the hooked body 92. In this case, the operator can remove the hook 130 from the hooked body 92 by pushing down the tip portion 133b of the pin body 133 of the hook 130 with a finger or the like.

As can be understood from the above description of the operation, according to the above-described embodiment, the load fastening belt 100 is an object that becomes the luggage WK by the adjustment belt body 110 and the bifurcated belt body 130 that are connected via the lock body 150. Since the load can be fixed at three points, a load having a relatively regular shape such as a cube or a rectangular parallelepiped can be stably fixed even if the load WK is a deformed object having more irregularities than the original. Further, since the lock body 150 can fix the adjustment belt body 110 at an arbitrary position and the position where the bifurcated belt body 130 is hung on the lock body 150 can be freely set, the load fastening belt 100 has a wide range of sizes and shapes. The luggage WK can be fixed. Further, since the load tightening belt 100 can arrange the lock body 150 at a relatively free position, it is possible to improve the workability of the work and prevent interference with the convex portions P1 and P2 of the load WK. By arranging the lock body 150 at the avoiding position, the luggage WK can be fixed without undue force or damage.

Further, the present invention is not limited to the above-described embodiment, but various modifications can be made without departing from the object of the present invention.

For example, in the above-described embodiment, the load fastening belt 100 is configured by including the luggage protection body 154 on the lock body 150. However, the luggage fastening belt 100 may be configured by omitting the luggage protector 154 when it is not necessary to consider damage to the luggage WK. Further, the luggage protector 154 may be provided only on the belt fixture 151 or the ring body 153. Further, in the luggage protector 154, the expansion portion 154b may be configured by one member, that is, the cut 154c may be omitted, or may be configured by three or more members. The luggage protector 154 is a material other than a material that can be manually deformed (for example, a woven fabric, a nonwoven fabric, or a rubber material), that is, a material that is difficult to deform manually, such as a resin or rubber plate body. It can also be configured.

Further, in the above-described embodiment, the load fastening belt 100 is configured by the hook 130 including the gate body 132. However, the hook 130 may be at least a metal fitting that can be hooked on the hooked body 92, and is not necessarily limited to the above embodiment. That is, the hook 130 can be configured by omitting the gate body 132. The hook 130 is a so-called flat hook formed by bending a flat hook body 131 into a flat plate. However, the hook 130 may be configured by other than a flat hook, for example, a key hook (also referred to as a narrow hook), a delta ring hook, an eggplant hook, a swivel hook, a chain hook, a snap hook, or the like.

Further, in the above-described embodiment, the hook 130 is configured by an inclined surface, specifically, a spherical surface, in which the tip portion 133b of the pin body 133 is inclined outward from the center portion of the upper surface toward the base portion 131a. However, the tip portion 133b of the pin body 133 may be formed in a shape other than a spherical shape, for example, a conical shape. Further, the tip portion 133b of the pin body 133 can be formed in a shape other than a circular shape in plan view, for example, a square or a polygon, and the tip portion 113b can also be formed flat. In these cases, the tip portion of the hook portion 131c of the hook 130 may be formed along the outer shape of the tip portion 133b of the pin body 133, or may be formed in a straight line shape or a curved shape that surrounds a part of the tip portion 133b. It can also be formed.

Further, in the above-described embodiment, the load fastening belt 100 fixes the load WK on the pallet 90. However, the load fastening belt 100 is not necessarily limited to the above embodiment as long as it is used when fixing the load WK for transportation and storage. That is, the load fastening belt 100 can fix the load WK to the floor surface on which, in addition to the pallet 90, a load carrier or anchor of the vehicle is installed, for example.
