Description

[Technical field]

[0001] The present invention relates to a rope tightening device. [Background technology]

[0002] When securing cargo on the bed of a truck or other vehicle, a rope is passed over the top of the cargo and then fastened to a hook on the bed. At this time, the rope is tightened to secure the cargo firmly so that the knot does not loosen due to vibrations during transport. There are various ways to secure the cargo, including a knot called the Nanking knot. However, tying methods such as the Nanking knot are not easy to master due to the complex steps involved, and only experienced people can properly secure the cargo while tightening the rope. Therefore, there is a need for a tool that allows anyone to easily tighten the rope and secure the cargo firmly.

[0003] In Patent Document 1, three branches are attached vertically to the main shaft in an E-shape. A pipe is attached along the main shaft branches, and a hook is attached to pass through the pipe. The hook has U-shaped ends protruding from the pipe, and a roller is attached to each curved part of the U-shape.

[0004] The rope is lowered from the load, wrapped around the top branch once, passed in front of the middle branch and passed behind the bottom branch. The rope is then hooked onto the fixed hook on the loading platform, and then hooked onto the roller of one of the hooks of the load-tie rope hook and pulled.

[0005] [Patent Document 1] Utility model application published: 63-056346 Summary of the Invention [Problem to be solved by the invention]

[0006] The above-mentioned cargo tie-down rope hook is composed of multiple components such as a main body, a pipe, and a roller, and the manufacturing process is complicated. The object of the present invention is to provide a cargo tie-down rope hook with a simple structure. [Means for solving the problem]

[0007] In order to solve the above problems, a first aspect of the present invention is a load-tie down rope hook having a rod-shaped main body shaft portion, a rod-shaped first branch portion having one end integrally attached to one end side of the main body shaft portion and perpendicular to the main body shaft portion, a rod-shaped second branch portion having one end integrally attached to the main body shaft portion and perpendicular to the main body shaft portion, located in a first plane including the main body shaft portion and the first branch portion, and a rod-shaped U-shaped hook portion having one end integrally attached to the main body shaft portion and located in a second plane including the main body shaft portion.

[0008] In a second aspect of the present invention, it is preferable that the other ends of the first and second branches have claw portions formed by bending the first and second branches toward one end of the main body shaft portion.

[0009] In the third aspect of the present invention, it is preferable that the first plane and the second plane are perpendicular to each other.

[0010] The fourth aspect of the present invention preferably has a detachable part that can be attached to and detached from another object. Effect of the Invention

[0011] According to the first aspect of the present invention, the rope is wound around the first branch, then around the second branch, and the rope is then hooked onto a hook on the loading platform or the like, and then pulled by the hook attached to the main shaft of the main body. This reduces the force required to pull the rope, and the rope can be tightened and secured firmly in place in a simple procedure. In addition, the rope hook has a simple structure, making it easy to manufacture.

[0012] According to the second aspect of the present invention, the cargo securing rope hook can prevent the rope wrapped around the first branch and the second branch from coming loose due to the warping of the claw portions at the other ends of the first branch and the second branch.

[0013] According to the third aspect of the present invention, the cargo securing rope hook prevents the first and second branches from getting in the way when the rope is hung on the hook portion, thereby shortening the time required for the work.

[0014] According to the fourth aspect of the present invention, the cargo tie-down rope hook can be prevented from being lost or dropped. [Brief description of the drawings]

[0016] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. In this embodiment, a cargo tie-down rope hook is used.

[0017] (composition) 1 and 2 are diagrams showing an example of the configuration of a cargo securing rope hook 1. FIG.

[0018] As shown in Figure 1, the securing rope hook 1 has a main body 10 and a hanging portion 20. The main body 10 has a main shaft 11, a first branch portion 13, a second branch portion 14, and a hook portion 12. The main shaft 11, the first branch portion 13, the second branch portion 14, and the hook portion 12 are formed as a whole integrally. The main body 10 is in the shape of a round bar having a thickness that does not deform even when a very strong force is applied thereto.

[0019] The main shaft 11 has a linear shape. At one end of the main shaft 11, a strap attachment portion 21 for the hanging portion 20 is formed. At that end of the main shaft 11, a first branch portion 13 is formed. The first branch portion 13 has a substantially linear shape and is perpendicular to the main shaft 11. A second branch portion 14 is formed between the first branch portion 13 and the other end of the main shaft 11. The second branch portion 14 also has a shape similar to that of the first branch portion 13 and has a substantially linear shape. The first branch portion 13 and the second branch portion 14 are provided in the same first plane (the xy plane in FIG. 1) and are therefore parallel to each other. As a result, the main shaft 11, the first branch portion 13, and the second branch portion 14 are formed in a substantially F-shape. At the other end of the main shaft 11, a hook portion 12 is formed.

[0020] The first branch portion 13 has a first claw portion 13a at an end portion thereof. The first claw portion 13a is formed so as to be curved toward one end side of the main shaft 11.

[0021] The second branch portion 14 has a second claw portion 14a at an end thereof. The second claw portion 14a is formed to be warped toward one end side of the main shaft 11, similar to the first claw portion 13a.

[0022] The hook portion 12 is a generally U-shaped hook. The hook portion 12 is provided in a second plane (the yz plane in FIG. 2) perpendicular to the first plane. As a result, the hook portion 12 faces in the z direction.

[0023] The hanging portion 20 has a strap attachment portion 21, a strap 22, and a clip portion 23. The strap attachment portion 21 is a round hole provided for attaching the strap 22 to the main shaft 11. One end of the strap 22 is attached to the strap attachment portion 21, and the other end is attached to the clip portion 23. In this way, the strap 22 connects the main body 10 and the clip portion 23. The clip portion 23 is a clip that can be detachably fastened to a rope or the like.

[0024] (action, effect, etc.) An example of the operation of this embodiment will now be described.

[0025] As shown in FIG. 3, the user winds the rope 30 around the first branch 13 once, after it has been attached to the luggage. Specifically, the user, with the cargo-tightening rope hook 1 positioned on the near side of the luggage, winds the rope 30 around the first branch 13 by passing it behind, under, in front, over, and back again. Here, when winding the rope 30 from the top of the first branch 13 to the back, the user shifts the rope 30 toward the first claw 13a side with respect to the existing rope 30 portion and winds it around. The user then winds the rope 30 that has been wound around the first branch 13 around the second branch 14 once. At this time, the user winds the rope 30 around the second branch 14 in the opposite direction to the winding direction around the first branch 13. Specifically, the user winds the rope 30 around the second branch 14 by passing it in front, under, in back, over, and back again. Here, when the user winds the rope 30 from above the second branch portion 14 to the hand, the user winds the rope 30 by shifting it toward the second claw portion 14a with respect to the existing portion of the rope 30.

[0026] Next, the user hooks the rope 30, which has been wound around the second branch 14, onto a bed hook 40 of a truck or the like carrying luggage, and then passes the rope over the hook portion 12 and hooks it onto the hook portion 12.

[0027] The user then pulls the rope 30 hooked on the hook portion 12 downward (arrow 50). This allows the rope 30 to be tightened. At this time, the hook portion 12 acts as a movable pulley, so that, due to the principle of the movable pulley, the rope 30 can be tightened with a force smaller than the force required to pull the rope 30 without hooking it on the hook portion 12. The user then wraps the rope 30 hooked on the hook portion 12 around, for example, the cargo bed hook 40 again to secure it. The user also attaches the clip portion 23 to the rope 30 before or after fastening the load.

[0028] (Effects of this embodiment) (1) The cargo securing rope hook 1 is used by winding the rope 30 around the first branch 13 and the second branch 14 in opposite directions, then passing the rope 30 over the platform hook 40 and then over the hook portion 12 and pulling it. At this time, less force is needed to pull the rope 30, and the cargo can be securely secured while tightening the rope 30 in a simple procedure. At this time, all that is needed is to wind the rope 30 around the first branch 13 and the second branch 14 and to pass it over the hook portion 12, so even an experienced person or a person without strong strength can easily secure the cargo with the rope. (2) The cargo-tie rope hook 1 is formed with a first claw portion 13a and a second claw portion 14a. Even if the rope 30 slides on the first branch portion 13 or the second branch portion 14, the first claw portion 13a and the second claw portion 14a stop the movement, preventing the rope 30 from coming off the first branch portion 13 or the second branch portion 14. Therefore, even when used on the bed of a truck, the rope 30 can be prevented from coming off the first branch portion 13 or the second branch portion 14 due to vibration or the like. (3) Because the first plane and the second plane are perpendicular to each other, the rope 30 can be easily passed through the hook portion 12 without being hindered by the first branch portion 13 and the second branch portion 14. For example, when the main body 10 is fastened to the rope 30, the hook portion 12 faces outward with respect to the load, so that the rope 30 can be easily passed through the hook portion 12. (4) In the Nanking knot, a long rope is required to make a loop for passing the rope attached to the cargo bed hook 40, but when the cargo tie-down rope hook 1 is used, there is no need to make such a loop, so a shorter length of rope will suffice. (5) The members of the main body 10 are integrated, so it has a strong, simple structure and is easy to manufacture. For example, in Patent Document 1, the member corresponding to the hook portion 12 is configured separately from the other members, so when the force pulling the rope 30 becomes strong, the member corresponding to the hook portion 12 may come off the other members and be damaged, but this does not happen with the cargo tie-down rope hook 1 of this embodiment. (6) By reversing the winding direction of the rope 30 around the first branch 13 and the second branch 14, the main body 10 does not shift from the place where it is tied to the rope 30. Therefore, the subsequent work can be done without placing hands on the main body 10. (7) The clip portion 23 of the hanging portion 20 of the cargo-tie rope hook 1 can be attached to the rope 30. This connects the rope 30 and the main body 10 with the strap 22, preventing the rope 30 from being lost or dropped when tying or untying the cargo.

[0029] (Modifications of this embodiment, etc.) As another example of the above embodiment, the configuration is not limited to one in which the first plane and the second plane are perpendicular to each other, and the main body 10 may be formed so that the first branch portion 13, the second branch portion 14 and the hook portion 12 are on the same plane, as long as there is a gap between the second branch portion 14 and the hook portion 12 that is large enough to allow the rope 30 to be easily passed through the hook portion 12, as shown in Figure 4.

[0030] As another example of the above embodiment, the use of the cargo securing rope hook 1 is not limited to the loading platform of a truck, but may be accomplished by hooking a rope onto a fixed rod such as rod 60 and tightening it, as shown in FIG. 5.

[0031] As another example of the above embodiment, the location and shape of the strap attachment part 21 do not have to be limited to a round hole in the main shaft 11 as shown in Fig. 1, as long as the strap 22 can be attached to the main body 10. Also, the hanging part 20 can have a different configuration as long as it is a detachable part that can be attached to another object. For example, both ends of a hook-and-loop fastener can be fastened to the main body 10 and the rope 30, respectively.

[0032] In the above embodiment, the main shaft may be a main shaft portion, the first claw portion and the second claw portion may be claw portions, and the hanging portion may be a detachable portion.

[0033] Further, while an embodiment of the present invention has been disclosed, it will be apparent to those skilled in the art that modifications may be made thereto without departing from the scope of the present invention, and all such modifications and equivalents are intended to be encompassed by the following claims.
