Description

This invention relates to a rope hook that is attached to a cart or loading platform and used to secure transported items with ropes, etc. In particular, it allows the user to select the position where the rope is hooked, and prevents the rope from shifting in position due to vibrations or impacts.

To secure transported goods to the bed of a truck, cart, bicycle, or other vehicle with a binding member such as a rope, hooks are provided around the periphery of the bed, and the end or middle of the rope is hooked onto these hooks to secure the transported goods.

Such hooks are usually rod- or L-shaped, and are installed at appropriate positions on the loading platform. They are used to hook the end or middle of the rope when wrapping the rope around the object being transported (Patent Document 1).

Also available as a hook is a metal rod bent into a roughly U-shape or roughly C-shape, with both ends attached to the periphery of the loading platform (Patent Document 2).

However, because the hooking device described in Patent Document 1 is fixedly attached to a predetermined position on the loading platform, it may be necessary to hook the rope in a slightly different position depending on the shape of the transported item. If the rope cannot be hooked in the desired position, the transported item may not be sufficiently secured.

Furthermore, the hooking device described in Patent Document 2, particularly the U-shaped hooking device, has a certain width and allows the position where the rope is hooked to be moved somewhat, but the range of movement is small, and it is not always possible to hook the rope in a position that matches the shape of the transported item. One possible solution to this problem is to increase the width of the U-shaped hooking device.

However, if the width of the U-shaped hook is increased, the rope hooked to the hook (specifically, its end or middle part) can move in the width direction of the hook. This creates the problem that if the transported item shifts due to vibration or impact during transport, the position where the rope was hooked will shift, causing the load to collapse.

In other words, because the hooks are attached to the side edges of the cart, their width coincides with the direction in which the goods are being transported (the front-to-back direction of the cart), and vibrations and shocks during transport can catch the rope and cause it to become misaligned.

The objective of this invention is to provide a rope hooking device that allows the rope hooking position to be selected appropriately in the direction in which the side edge of the loading platform extends, and that prevents the secured fastening of the transported object from loosening even when subjected to vibrations or shocks during transport, thereby maintaining stable fastening of the transported object.

In order to solve the above problem, the invention described in claim 1 is a rope hook that is installed at predetermined positions on opposing side edges of a loading platform on which an object to be transported is placed, and is characterized by comprising: a U-shaped or C-shaped hook member having a hook portion onto which the end or middle portion of a rope used to secure the object to be transported is hooked, and an attachment portion that is attached to the side edge of the loading platform; and a separate member that is stretched between the middle portion of the hook portion and the side edge of the loading platform, dividing the space between the hook member and the loading platform and forming at least two insertion holes.

The invention described in claim 2 is the rope hook described in claim 1, characterized in that the hooking member includes an attachment plate to which the mounting portion and the separate member are attached, and the hooking member is attached to the cargo bed via the attachment plate.

The invention described in claim 3 is a rope hook that is attached to predetermined positions on opposing side edges of a loading platform on which an object to be transported is placed, and is characterized by comprising: a joint for attaching to the side edge of the loading platform; a hook for hooking the end or middle portion of a rope for fastening the object to the loading platform; a U-shaped or C-shaped rope engagement portion having an attachment portion that connects to the joint; and a separate portion that spans between the middle portion of the hook and the joint, dividing the space between the rope engagement portion and the joint, and forming at least two insertion holes.

According to the invention described in claim 1, by attaching a U-shaped or C-shaped hooking member to the side edge of the loading platform, the hooking portion extends in a direction along the side edge of the loading platform, and the separate member divides the space between the hooking member and the loading platform, forming at least two insertion holes. This allows the rope hooking position to be selected appropriately in the direction in which the side edge of the loading platform extends, allowing for flexible fastening of transported items.

In addition, because the separation member separates the space between the hooking member and the loading platform, the position where the rope is hooked will not move even if vibrations or shocks occur during transport, so the secured load of the transported item will not loosen, preventing the load from collapsing.

According to the invention described in claim 2, by making the mounting plate attached to the cargo bed part of the hooking member, the hooking member including the mounting plate can be made into a single component, and can be retrofitted to existing cargo beds.

According to the invention described in claim 3, a U-shaped or C-shaped rope engagement portion is provided on the side edge of the loading platform, so the hooking portion extends along the side edge of the loading platform, and the separate portion divides the space between the rope engagement portion and the loading platform, forming at least two insertion holes. This allows the rope's hooking position to be selected appropriately in the direction in which the side edge of the loading platform extends, allowing for flexible fastening of transported goods. Furthermore, because the separate portion divides the space between the rope engagement portion and the loading platform, the hooking position of the rope does not move even with vibrations or impacts during transport, so the fastening of transported goods does not loosen, preventing the load from falling over.

FIG. 10 is a front view showing another embodiment of the rope hook according to the present invention. FIG. 10 is a plan view of the rope hook of FIG. 9 . FIG. 10 is a right side view of the rope hook of FIG. 9 .

The present invention will be described below based on the illustrated embodiment.

Figures 1 to 3 show a trolley equipped with the rope hook of the present invention. The trolley 1 comprises a trolley body 2, six casters 3 provided on the underside of the trolley body 2, and supports 4 provided at the four corners of the trolley body 2.

The bogie body 2 consists of L-shaped corner members 5 provided at each of the four corners, outer frame members 6 that connect these corner members 5 front to back or left to right, and inner frame members 7 that connect opposing outer frame members 6. These outer frame members 6 and inner frame members 7 are made of, for example, hollow rectangular pipes made of aluminum alloy. The corner members 5 are also made of aluminum alloy, for example, formed by extrusion molding.

Three lower plates 8 are attached to the underside of the bogie body 2, near both longitudinal edges and in the center, spanning the two outer frame members 6 extending in the longitudinal direction, and the casters 3 are mounted on these lower plates 8.

In addition, on the top surface of the bogie body 2, except for the positions where the two lower plates 8 at the front and rear are provided, and at the center of the width of the central lower plate 8, an upper plate 9 consisting of an H-shaped checkered plate in a plan view is attached so as to bridge between the two outer frame members 6 extending in the longitudinal direction, and the transported goods are loaded on this upper plate 9.

A vertically penetrating insertion hole is formed in the corner of the corner member 5, into which the support post 4 is inserted. The support post 4 may be provided so that it can be inserted and removed freely from the insertion hole of the corner member 5, or it may be a bendable support post with its lower part fixed to the insertion hole of the corner member 5 at an appropriate position.

The rope hook 10 of the present invention is attached to a predetermined position on the side edge of the bogie body 2 of such a bogie 1. Specifically, the bogie rope hook 10 is attached to the outer frame material 6 that constitutes the bogie body 2 as a loading platform. Because the rope hook 10 is attached to the side edge of the bogie body 2, for the sake of explanation, the front of the rope hook 10 is synonymous with the side of the bogie 1.

As shown in Figures 4 to 8, the rope hook 10 consists of a mounting plate 11 attached to the outer surface of the outer frame material 6 that constitutes the bogie body 2, a hook member 12 made of a round bar bent into a U-shape and attached to the mounting plate 11 at both ends, and a separate member 13 that spans the center of the mounting plate 11 and the hook member 12.

The mounting plate 11, hook member 12, and separate member 13 are made of, for example, an aluminum alloy. The mounting plate 11 is an L-shaped angle, the hook member 12 is a round bar, and the separate member 13 is made of a plate, and the components are joined together by welding or other means.

The hook member 12, formed by bending it into a U-shape, consists of mounting portions 14 whose ends are welded to the mounting plate 11, and hook portions 15 that face parallel to the mounting plate 11. When the mounting portions 14 on both ends are attached to the mounting plate 11, a space 16 is formed between the mounting plate 11 and the hook member 12.

The separate member 13 is welded at both ends so that it spans the center of the mounting plate 11 (relative to the rope hook 10) in the left-right direction and the center of the hook portion 15 (relative to the rope hook 10), thereby dividing the space 16 and forming two insertion holes 17. These insertion holes 17 are large enough to allow the rope to pass through.

This type of rope hook 10 has mounting plates 11 riveted to the outer frame material 6 at two locations spaced apart from each other at the front and rear of the outer frame material 6 (relative to the bogie 1).

In addition, a hook 20 is attached approximately in the center of the short-side edge (outer frame material 6) of the bogie body 2. Unlike the rope hook 10 described above, this hook 20 is formed by bending a rod into a U-shape and does not have any separate components. This is because the vibration and impact of the transported object are minimal in the short-side direction. Of course, the rope hook 10 described above can also be attached to the short-side edge of the bogie body 2.

When using such a rope hook 10 to secure an object, one end of the rope is secured to one of the rope hooks 10 using its insertion hole 17, the rope is wrapped around the object, and the rope is then hooked into the insertion hole 17 of the rope hook 10 on the opposite side.

In this way, the rope can be wrapped around the object while hooking it onto a rope hooking device 10, and the end of the rope can be hooked onto another rope hooking device 10 to tighten it up, thereby securing the object.

In this case, since the rope hook 10 has two adjacent insertion holes 17, it is possible to select the insertion hole 17 that is deemed best for securing the transported item.

Even if the transported item shifts due to vibration or impact during transport, the narrow insertion hole 17 of the rope hook 10 through which the rope is hooked will prevent the rope from shifting from the hooked position, thereby maintaining the secured state of the transported item.

The rope hook 10 according to the above embodiment is equipped with a mounting plate 11, and can be attached to an existing truck simply by attaching the mounting plate 11 to the side edge of the truck body 2 (the outer frame material 6 in this embodiment) which serves as the loading platform. Furthermore, even if a truck already has a hook, if the position of the hook is not appropriate, the rope hook 10 according to this embodiment can be easily attached and the rope can be hooked in the desired position. In short, the rope hook 10 according to the present invention can be easily retrofitted to an existing loading platform.

The rope hook 10 in the above embodiment has been described as having one separate member 13, but this is not limited to this; multiple separate members may be provided. By providing multiple rope hooks 10, the number of points at which the rope can be hooked increases, making it possible to secure the transported object in an appropriate position and also making it possible to secure the transported object with an irregular shape.

As described above, with the rope hook 10 of the present invention, the C- or U-shaped hook member 12 is attached to the side edge of the loading platform (the outer frame material 6 of the dolly body 2), so that the hook portion 15 extends in a direction along the side edge of the loading platform, and the separate member 13 divides the space 16 between the hook member 12 and the loading platform, forming at least two insertion holes 17. This allows the rope hooking position to be selected appropriately in the direction in which the side edge of the loading platform extends, allowing for flexible fastening of transported items.

In addition, because the separation member 13 separates the space between the hooking member 12 and the loading platform, the position where the rope is hooked will not move even if vibrations or shocks occur during transport, so the secured load of the transported goods will not loosen, preventing the load from collapsing.

In other words, by providing the separate member 13, the spacing between the insertion holes 17 can be reduced, preventing the rope from moving. Even if the transported item moves slightly due to vibrations and impacts caused by the movement of the cart 1, the hooking position of the rope remains fixed and the rope does not loosen. As a result, the rope does not come off the transported item, preventing the load from shifting.

Furthermore, since the rope hook 10 according to the above embodiment is provided with an attachment plate 11, the hook member 12 including the attachment plate 11 can be made into a single component, and can be retrofitted to existing cargo beds.

If such a mounting plate 11 is not available, the mounting portion 14 of the hook member 12 and the separate member 13 can be attached directly to the cargo bed (outer frame material 6).

In addition, while the mounting plate 11 is attached to the outer frame material 6 using rivets, the present invention is not limited to this and mechanical joining using screws, bolts, etc. is also acceptable. Furthermore, while the joining between other components has been described as welding, the joining is not limited to this and material joining using brazing, soldering, etc. is also acceptable.

Furthermore, while the hooking member 12 has been described as being formed by bending a round bar material into a U-shape, the present invention is not limited to this, and it may also be formed by bending a square bar material or bending it into a U-shape.

In the above embodiment, the separating member 13 was described as a plate material, but it is not limited to this and may also be a round bar material.

The above describes an embodiment of the present invention, but the specific configuration is not limited to the above embodiment, and design changes that do not deviate from the gist of the invention are still included in the present invention. For example, although it is called a rope hook, it is not limited to ropes; it can also be applied to hooks for hooking binding materials such as belts and strings. Furthermore, while the above embodiment describes a dolly 1 equipped with casters 3, the present invention is not limited to this and can be applied to bicycle carriers, cargo trays, and other items on which transported items are placed and secured with ropes.

In addition, in the above embodiment, the rope hook 10 is formed/constructed by joining multiple components, such as the mounting plate 11, hooking member 12, and separate member 13, by welding or the like. However, as shown in Figures 9 to 11, the rope hook 10 may also be constructed such that the joint portion 31, rope engagement portion 32, and separate portion 33 are integrally formed (for example, cast as a single piece from an aluminum alloy). The mounting plate 11 in the above embodiment corresponds to the joint portion 31, the hooking member 12 corresponds to the rope engagement portion 32, and the separate member 13 corresponds to the separate portion 33.

In this case, the rope hook 10 is configured to include a joint 31 for attaching to the side edge of the loading platform on which the transported goods are placed, a hook 15 around which the end or middle portion of the rope used to secure the transported goods is hooked, a C-shaped or U-shaped rope engagement part 32 having an attachment part 14 that connects to the joint 31, and a separate part 33 that spans between the middle part of the hook 15 and the joint 31, dividing the space 16 between the rope engagement part 32 and the joint 31 and forming at least two insertion holes 17.

The joint 31 consists of a side plate 31a that runs along a vertical plane and a bottom plate 31b that runs along a horizontal plane. The bottom plate 31b connects to the lower end of the side plate 31a, forming an L-shape when viewed from the side of the rope hook 10 (see Figure 11).

The rope engagement portion 32 is formed in a U-shape (or may be U-shaped) in plan view (see Figure 10), and comprises an attachment portion 14 whose ends (specifically, the ends of a pair of parallel, opposing sides of the U-shape) connect to the joint 31, and a hook portion 15 that faces parallel to the joint 31. The attachment portion 14, which is a pair of parallel, opposing sides of the U-shape, connects to the joint 31, forming a space 16 between the joint 31 and the rope engagement portion 32.

The separate portion 33 is connected at both ends in the front-to-rear direction (relative to the rope hook 10) so as to bridge the center of the joint portion 31 in the left-to-right direction (relative to the rope hook 10) and the center of the hook portion 15 in the left-to-right direction (relative to the rope hook 10), thereby dividing the space 16 and forming two insertion holes 17. These insertion holes 17 are large enough to allow the rope to pass through.

The rope hook 10 is attached to the outer surface of the outer frame material 6 that constitutes the bogie body 2 at two locations spaced apart at the front and rear (from the bogie 1) of the bogie. When in the orientation when attached to the bogie 1, it is fastened, for example, by rivets via two through-holes 311 spaced apart on the left and right (from the rope hook 10) in the side plate portion 31a of the joint 31 (fastened to the side of the outer frame material 6) and via two through-holes 312 spaced apart on the left and right (from the rope hook 10) in the bottom plate portion 31b of the joint 31 (fastened to the bottom surface of the outer frame material 6).

With the above-described rope hook 10, the C- or U-shaped rope engagement portion 32 is attached to the side edge of the loading platform (specifically, the outer frame material 6 of the trolley body 2), allowing the hook portion 15 to extend along the side edge of the loading platform, and the separate portion 33 divides the space 16 between the rope engagement portion 32 and the loading platform, forming at least two insertion holes 17. This allows the rope hooking position to be selected appropriately in the direction in which the side edge of the loading platform extends, allowing for flexible fastening of transported goods. Furthermore, because the separate portion 33 divides the space between the rope engagement portion 32 and the loading platform, the hooked position of the rope will not move even with vibrations or impacts during transport, thereby preventing the fastening of transported goods from loosening and preventing the load from falling over.
