Cargo tie-down rope holder

Abstract

To simplify the structure of a load-fastening rope holder, prevent the rope from loosening, and reduce the load on a lock part. [Solution] The rope holder 10 has a main body 11 capable of engaging the fixed side rope R1, and a lever 12 capable of locking the cargo securing side rope R2. The main body has an inlet portion (inlet hole 11f) and an outlet portion (exit hole 11g) for the cargo securing side rope, and is configured so that the cargo securing side rope can be inserted from the inlet portion, folded back inside the main body, and pulled out from the outlet portion. The operating lever 12a and the lock lever 12b of the lever 12 are flexibly interconnected at a joint portion (concave cone 12a4 and convex cone 12b5). When the levers 12a and 12b are in a locked state bent in a first direction, they lock the cargo securing side rope R2 to the main body 11 at a position inside the outlet portion, and when they are in a free state bent in a second direction different from the first direction, they free the cargo securing side rope R2 from the main body 11 at a position inside the outlet portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Hereinafter, a first embodiment and a second embodiment of the rope holder according to the present invention will be described with reference to the drawings. Note that the same or corresponding parts are designated by the same reference numerals throughout the drawings, and duplicated explanations will be omitted as appropriate.

[0009] First embodiment Fig. 1 shows a rope holder 10 according to a first embodiment of the present invention, where (a) is a perspective view, (b) is a side view, (c) and (d) are see-through views of a toggle lever, (e) is a perspective view of an operating lever, and (f) is a perspective view of a lock lever. The rope holder 10 has a main body 11 and a toggle lever 12. The main body 11 and the toggle lever 12 can be made of resin, metal, or the like.

[0010] The toggle lever 12 is composed of an operating lever 12a that is manually operated, and a lock lever 12b that locks the load-tightening rope R2. As shown in Fig. 1(c), the operating lever 12a is supported by a support shaft 13 that is inserted from the outside of the main body 11. The lock lever 12b is also supported by a support shaft 14 that is inserted from the outside of the main body 11.

[0011] The shaft 13 is inserted into a shaft hole 12a3 formed in the longitudinal middle of the operating lever 12a. The shaft 14 is inserted into a shaft hole 12b4 formed in the longitudinal middle of the lock lever 12b. The operating lever 12a and the lock lever 12b have lightening recesses 12a5 and 12b6 formed on both side surfaces thereof to reduce weight.

[0012] 2, the main body 11 has a pair of mutually opposing side plate portions 11a, a bottom plate portion 11b, a front plate portion 11c, and a partition plate portion 11d. The side plate portions 11a and the bottom plate portion 11b are connected in a U-shape. In addition, the front portions of the side plate portions 11a are interconnected by the front plate portion 11c.

[0013] The partition plate portion 11d is disposed parallel to the bottom plate portion 11b. The front end of the partition plate portion 11d is continuous with the front plate portion 11c, and the inner surfaces of the side plate portions 11a are interconnected by the partition plate portion 11d. The pair of left and right side plate portions 11a are configured to be elastically displaceable in the directions of the arrows in FIG.

[0014] A through hole 11b1 is formed in the center of the bottom plate portion 11b in the front-rear direction. The through hole 11b1 is configured so that an end of a fixed side rope R1 (or a carabiner hook CH in FIG. 4, etc.) fixed to the loading platform can be connected to the through hole 11b1.

[0015] An inlet hole 11f as an inlet for the load-tightening rope R2 and an outlet hole 11g as an outlet are formed at two places, upper and lower, of the front plate portion 11c. These inlet hole 11f and outlet hole 11g are located above and below the partition plate portion 11d.

[0016] The cargo-tightening rope R2 that is wound around the cargo loaded on the platform is inserted through the entrance hole 11f, passed between the bottom plate 11b and the partition plate 11d, and pulled in to the rear end 11d1 of the partition plate 11d. After that, the rope R2 is folded back upward at the rear end 11d1, and can be pulled out from the exit hole 11g while being aligned with the upper surface of the partition plate 11d.

[0017] The side plate portion 11a is formed with round holes 11a3 and 11a4 for fitting both ends of the support shafts 13 and 14 that support the operating lever 12a and the lock lever 12b. A stopper 11a5 for the operating lever 12a protrudes from the inner surface of the side plate portion 11a near the round hole 11a3.

[0018] The operating lever 12a and the lock lever 12b are disposed between a pair of left and right side plates 11a so as to contact the inner surface of the side plate 11a. The operating lever 12a and the lock lever 12b can be easily assembled by simply aligning the shaft holes 12a3 and 12b4 of the levers 12a and 12b with the round holes 11a3 and 11a4 of the side plate 11a and inserting the two support shafts 13 and 14 into the round holes 11a3 and 11a4 and the shaft holes 12a3 and 12b4 from the outside of the side plate 11a.

[0019] ●Details of the operation lever and lock lever The operating lever 12a and the lock lever 12b are flexibly connected to each other by the mutual engagement of a convex cone 12b5 and a concave cone 12a4 as a joint portion. That is, the convex cone 12b5 formed on one end of the lock lever 12b is rotatably engaged with the concave cone 12a4 formed on one end of the operating lever 12a.

[0020] The operating lever 12a and the lock lever 12b are interconnected so as to be able to be bent between a locked state in which they are bent in a first direction as shown in Fig. 3(c) and a free state in which they are bent in a second direction different from the first direction as shown in Fig. 3(a). In the locked state of Fig. 3(c), the load-tightening rope R2 is locked to the main body 11 as shown in Fig. 4(b), and in the free state of Fig. 3(a), the load-tightening rope R2 is free from the main body 11 as shown in Fig. 4(a).

[0021] In the locked state of Fig. 3(c) and the free state of Fig. 3(a), the convex cone 12b5 of the lock lever 12b fits into the concave cone 12a4 of the operating lever 12a. Also, as shown in Fig. 3(b), in an intermediate state between the locked state and the free state, the convex cone 12b5 and the concave cone 12a4 are separated (misaligned) in the direction perpendicular to the axial direction.

[0022] A stepped groove 12b3 is formed on the underside of the tip of the lock lever 12b as a locking portion that can engage with the upper surface of the load-tightening rope R2. Meanwhile, a stepped groove 11d2 is formed on the upper surface of the partition plate 11d of the main body 11 that can engage with the lower surface of the load-tightening rope R2.

[0023] The front end of the stepped groove 11d2 of the partition plate portion 11d ends inside the outlet hole 11g of the front plate portion 11c. The stepped groove 12b3 of the lock lever 12b and the stepped groove 11d2 of the partition plate portion 11d face each other in the vertical direction with the rope R2 sandwiched therebetween in the locked state of FIG. 4B(a).

[0024] How to use the rope holder of the first embodiment Next, a method of using the rope holder 10 according to the first embodiment will be described with reference to Figures 3 and 4. First, as shown in Figure 3, the fixed rope R1 is passed through the through hole 11b1 of the bottom plate portion 11b of the main body 11 and fixed. The fixed rope R1 may be connected to the bottom plate portion 11b via a carabiner hook CH or the like.

[0025] Next, the operating lever 12a is rotated upward as shown in Fig. 3(a) and Fig. 4(a) to set the rope-passing state. In this rope-passing state, the tip of the lock lever 12b moves upward, and the space between the stepped groove 12b3 and the stepped groove 11d2 is wide open. In this rope-passing state, the load-tightening rope R2 is inserted into the inlet hole 11f of the main body 11, and the rope R2 is passed between the bottom plate portion 11b and the partition plate portion 11d of the main body 11 and pulled to the rear end portion 11d1 of the partition plate portion 11d.

[0026] The load-tightening rope R2 thus pulled in is then folded back at the rear end 11d1 to the opposite side (front) and pulled out from the outlet hole 11g of the main body 11 while being aligned along the upper surface of the partition plate portion 11d. Next, the operating lever 12a is rotated downward as shown in Figure 3(c) and Figures 4(b) and (c) to enter the locked state or additional tightening state.

[0027] 3(b) shows an intermediate state between the free state and the locked state, in which the operating lever 12a and the lock lever 12b are aligned in a straight line. Since the positions of the support shaft 13 of the operating lever 12a and the support shaft 14 of the lock lever 12b are fixed, in the intermediate state the concave cone 12a4 of the operating lever 12a and the convex cone 12b5 of the lock lever 12b are separated (displaced) in the direction perpendicular to the axial direction.

[0028] 3(b), the operating lever 12a and the lock lever 12b are separated in the width direction within the main body 11 due to the misalignment between the concave cone 12a4 and the convex cone 12b5. The main body 11 is configured to be elastically displaceable in the width direction (left and right direction) shown by the arrow in FIG. 2, so that the operating lever 12a and the lock lever 12b are elastically pressed against the inner surface of the side plate portion 11a of the main body 11 due to the misalignment between the concave cone 12a4 and the convex cone 12b5. In this way, when the operating lever 12a is operated, the operating lever 12a and the lock lever 12b are elastically pressed against the inner surface of the side plate portion 11a of the main body 11, so that a smooth operation feeling without rattling of the toggle lever 12 can be obtained.

[0029] In the tightened state shown in Fig. 4(c), the tip of the lock lever 12b moves downward as shown in Fig. 3(c), narrowing the gap between the stepped groove 12b3 and the stepped groove 11d2. In this state, the securing rope R2 pulled out of the exit hole 11g is pulled strongly forward (upward in Fig. 4(c)) by hand (tightening). At this time, a force twice as large as the force applied by hand can be applied to the fixed rope R1 due to the "pulley principle."

[0030] During retightening, the tip of the lock lever 12b can move upward due to the misalignment of the concave cone 12a4 and the convex cone 12b5, so the load-tightening rope R2 is not locked in the stepped grooves 12b3 and 11d2. Even if you temporarily release the load-tightening rope R2 during retightening, the toggle lever 12 will be in the locked state as shown in Figures 3(c) and 4(b), so the rope R2 will not loosen. Therefore, the rope R2 can be easily retightened.

[0031] In the locked state shown in Fig. 3(c) and Fig. 4(b), the operating lever 12a and the lock lever 12b are bent upward (in a first direction), and the concave cone 12a4 of the operating lever 12a fits into the convex cone 12b5 of the lock lever 12b. This causes a force to act downward on the tip of the lock lever 12b (stepped groove 12b3) due to the tension of the load-tightening rope R2. Therefore, even if the load-tightening rope R2 is released as shown in Fig. 4(d), the locked state shown in Fig. 3(c) and Fig. 4(b) is maintained (self-locking).

[0032] A force smaller than the tension of the securing rope R2 acts on the stepped groove 12b3 as the locking portion. This is because the securing rope R2 is turned 180° in the opposite direction at the rear end 11d1 of the partition plate portion 11d, and the portion turned in the opposite direction is locked to the main body 11 by the lock lever 12b just before the exit hole 11g.

[0033] That is, the tension of the load-tightening rope R2 is significantly reduced by surface friction between the rear end 11d1 of the partition plate portion 11d and the stepped groove 12b3 of the lock lever 12b, and as a result, the load acting on the lock lever 12b can be significantly reduced. This effect of significantly reducing the load can significantly improve the durability of the lock lever 12b. In contrast, the rope holders of Patent Documents 3-5 have the problem that the rope tension is directly applied to the lock part, resulting in poor durability of the lock part.

[0034] In the self-locking state, the stepped groove 12b3 of the lock lever 12b and the stepped groove 11d2 of the partition plate portion 11d bite into the surface of the load-tightening rope R2, preventing the rope R2 from slipping in the locked state. Therefore, there is no risk of the load-tightening rope R2 accidentally loosening due to vibrations, etc., when transporting a load on a truck or the like, causing the load to collapse.

[0035] When loosening the load-tightening rope R2, the operating lever 12a is rotated upward to a free state as shown in Fig. 3(a). In this free state, the operating lever 12a rotates counterclockwise around the support shaft 13 and abuts against the stopper 11a5.

[0036] Therefore, there is no risk of the operating lever 12a rotating too quickly and injuring the fingers, etc. Also, when the operating lever 12a rotates counterclockwise, it rotates while being elastically pressed against the inner surface of the side plate portion 11a, so the operating lever 12a does not move wildly as soon as it is released.

[0037] Furthermore, the lock lever 12b rotates clockwise around the support shaft 14. The convex cone 12b5 of the lock lever 12b fits into the concave cone 12a4 of the operating lever 12a, thereby maintaining the free state of FIG.

[0038] That is, the lock lever 12b is bent downward (in a second direction different from the first direction). As a result, the stepped groove 12b3 at the tip of the lock lever 12b is separated from the load-tightening rope R2, and the load-tightening rope R2 becomes free with respect to the main body. Therefore, the load-tightening rope R2 can be easily pulled out from the inlet hole 11f of the main body 11.

[0039] Second embodiment 5A and 5B are perspective views showing a locked state (FIG. 5A) and a free state (FIG. 5B) of a load-securing rope holder 10 according to one embodiment of the present invention. This rope holder 10 has a main body 11 shown in FIGS. 6(a)-(f) and a toggle lever 12 shown in FIG. 7. The main body 11 and the toggle lever 12 can be made of resin, metal, or the like.

[0040] The main body 11 has a pair of mutually opposing side plate portions 11a, a bottom plate portion 11b, a front plate portion 11c, and a partition plate portion 11d. The side plate portions 11a and the bottom plate portion 11b are connected in a U-shape as shown in Fig. 6(e). The front portions of the side plate portions 11a are interconnected by the front plate portion 11c.

[0041] Fig. 6(f) shows the FF cross section of Fig. 6(e). As can be seen from Fig. 6(f), the partition plate portion 11d is disposed parallel to the bottom plate portion 11b. The front end of the partition plate portion 11d is continuous with the front plate portion 11c, and as can be seen from Fig. 6(e), the inner surfaces of the side plate portions 11a are interconnected by the partition plate portion 11d.

[0042] A through hole 11e for the fixed side rope R1 is formed at the rear end of the bottom plate portion 11b. The through hole 11e is configured so that an end of the fixed side rope R1 fixed to the loading platform can be connected to the through hole 11e.

[0043] An inlet hole 11f and an outlet hole 11g for the load-tightening rope R2 are formed at two positions, one above and one below, of the front plate portion 11c. These inlet holes 11f and outlet holes 11g are located above and below the partition plate portion 11d.

[0044] The cargo-tightening rope R2 that is wound around the cargo loaded on the platform is inserted through the entrance hole 11f, passed between the bottom plate 11b and the partition plate 11d, and pulled in to the rear end 11d1 of the partition plate 11d. After that, the rope R2 is folded back upward at the rear end 11d1, and can be pulled out from the exit hole 11g while being aligned with the upper surface of the partition plate 11d.

[0045] The side plate portion 11a is formed with a round hole 11a1 and an elongated hole 11a2 for supporting the toggle lever 12. The toggle lever 12 is composed of an operating lever 12a that is manually operated, and a lock lever 12b that locks the load-tightening side rope R2.

[0046] ●Details of the operation lever and lock lever The operating lever 12a and the lock lever 12b are flexibly connected to each other by a connecting shaft 12c as a joint. That is, the operating lever 12a and the lock lever 12b are flexibly connected to each other in a locked state where they are bent in a first direction as shown by the solid line in Fig. 7, and in a free state where they are bent in a second direction different from the first direction as shown by the chain line in Fig. 7. In the locked state, the load-tightening rope R2 is locked to the main body 11 as shown in Fig. 8B(a), and in the free state, the load-tightening rope R2 is free from the main body 11 as shown in Fig. 8B(b).

[0047] A support shaft 12a1 is formed on each of the left and right sides of the operating lever 12a. The support shaft 12a1 is rotatably supported in a round hole 11a1 in the side plate portion 11a of the main body 11.

[0048] Furthermore, a support shaft 12b1 is formed on both the left and right sides of the lock lever 12b. The support shaft 12b1 is slidably supported in a long hole 11a2 in the side plate portion 11a of the main body 11. An extension line of the longitudinal tip of the lock lever 12b is inclined toward the front plate portion 11c of the main body 11.

[0049] The length of the long hole 11a2 is set to a length that allows the connecting shaft 12b1 to move so that a sufficiently large gap for inserting the rope R2 is formed between the stepped groove 12b3 as the locking portion of the lock lever 12b and the stepped groove 11d2 of the partition plate portion 11d when the operating lever 12a and the lock lever 12b are reversely bent from the locked state shown in Fig. 8B(a) to the free state shown in Fig. 8B(b). In other words, the length of the long hole 11a2 is set so as to allow the connecting shaft 12b1 to move when transitioning from the locked state shown by the solid line in Fig. 7 to the free state shown by the dashed line.

[0050] A pair of left and right notch portions 12b2 having a V-shaped cross section are formed near the connecting shaft of the lock lever 12b. A tip corner portion 12a2 serving as a fitting portion of the operating lever 12a can be fitted into the notch portions 12b2 in the locked state shown in FIG. 8B(a).

[0051] A stepped groove 12b3 that can engage with the upper surface of the load-tightening rope R2 is formed on the underside of the tip of the lock lever 12b. Meanwhile, a stepped groove 11d2 that can engage with the lower surface of the load-tightening rope R2 is formed on the upper surface of the partition plate 11d of the main body 11.

[0052] The front end of the stepped groove 11d2 of the partition plate portion 11d ends inside the outlet hole 11g of the front plate portion 11c. The stepped groove 12b3 of the lock lever 12b and the stepped groove 11d2 of the partition plate portion 11d face each other in the vertical direction with the rope R2 sandwiched therebetween in the locked state of FIG. 8B(a).

[0053] How to use the rope holder of the second embodiment Next, a method of using the rope holder 10 according to the second embodiment will be described with reference to Figures 8A and 8B. First, the fixed rope R1 is passed through the through hole 11e of the main body 11 and fixed as shown in Figure 8A(a).

[0054] Next, the operating lever 12a is rotated upward as shown in Fig. 8A(a) to set the rope-passing state. In this rope-passing state, the tip of the lock lever 12b moves upward, and the gap between the stepped groove 12b3 and the stepped groove 11d2 is widened. In this rope-passing state, the load-tightening rope R2 is inserted into the inlet hole 11f of the main body 11, and the rope R2 is passed between the bottom plate portion 11b and the partition plate portion 11d of the main body 11 and pulled to the rear end portion 11d1 of the partition plate portion 11d (step 1).

[0055] The load-tightening rope R2 thus pulled in is then folded back at the rear end 11d1 to the opposite side (front) and pulled out from the outlet hole 11g of the main body 11 while being aligned along the upper surface of the partition plate portion 11d (Step 2). Next, the operating lever 12a is rotated downward as shown in Fig. 8A(b) to enter an additional tightening state (Step 3).

[0056] In this tightened state, the tip of the lock lever 12b moves downward, narrowing the gap between the stepped groove 12b3 and the stepped groove 11d2. In this state, the load-tightening rope R2 pulled out from the exit hole 11g is pulled forward strongly by hand (tightening, step 4). At this time, a force twice as large as the force applied by hand can be applied to the fixed rope R1 due to the "pulley principle."

[0057] During retightening, the support shaft 12b1 of the lock lever 12b can move along the long hole 11a2, and the tip of the lock lever 12b can move upward, so the load-tightening side rope R2 is not locked in the stepped grooves 12b3 and 11d2. Even if the load-tightening side rope R2 is temporarily released during retightening, the toggle lever 12 is in the locked state as shown in Fig. 8B(a), so the rope R2 does not loosen. Therefore, the rope R2 can be easily retightened.

[0058] 8B(a), the operating lever 12a and the lock lever 12b are bent upward (in a first direction), and the tip corner 12a2 of the operating lever 12a fits into the notch 12b2 of the lock lever 12b. Also, the support shaft 12b1 of the lock lever 12b abuts against the lower end of the long hole 11a2.

[0059] As a result, the tension of the securing rope R2 exerts a downward force on the tip of the lock lever 12b (the stepped groove 12b3). Therefore, even if you release the securing rope R2, the locked state shown in FIG. 8B(a) is maintained (self-locking).

[0060] In this self-locking state, the stepped groove 12b3 of the lock lever 12b and the stepped groove 11d2 of the partition plate portion 11d bite into the surface of the load-tightening rope R2, preventing the rope R2 from slipping in the locked state. Therefore, there is no risk of the load-tightening rope R2 accidentally loosening due to vibrations, etc., when transporting a load on a truck or the like, causing the load to collapse.

[0061] When loosening the load-tightening rope R2, the operating lever 12a is rotated upward to a free state as shown in Fig. 8B(b) (Step 5). In this free state, the operating lever 12a rotates clockwise around the pivot 12a1, and the lock lever 12b rotates counterclockwise around the pivot 12b1. In addition, the tip corner 12a2 of the operating lever 12a is released from the notch 12b2.

[0062] That is, the lock lever 12b is bent downward (in a second direction different from the first direction). As a result, the stepped groove 12b3 at the tip of the lock lever 12b is separated from the load-tightening rope R2, and the load-tightening rope R2 becomes free with respect to the main body. Therefore, the load-tightening rope R2 can be easily pulled out from the inlet hole 11f of the main body 11 (step 6).

[0063] Comparison with conventional technology In contrast, the rope holder of Patent Document 3, as shown in Fig. 9, locks the rope 14 with claws 2, and provides a ratchet wheel on roller 8 to prevent the rope 14 from loosening. Paragraph

[0019] of Patent Document 3 states, "The roller 8 is configured to be freely rotatable in the pulling direction of rope 14 (arrow P) and to be stopped in the opposite direction, so that when the rope 14 is pulled to secure a load, it can be done smoothly without being pulled back after pulling."

[0064] However, in the rope holder of Patent Document 3, there is a possibility that the rope 14 may unexpectedly come off the roller 8 due to vibrations, etc., when a load is transported by a truck or the like, and if this occurs, the locking of the rope 14 by the claw 2 may no longer be effective, and the load may collapse. In this embodiment, the rope R2 is securely locked by the toggle lever 12 in the locked state as shown in Fig. 8B(a), so there is no risk of the rope R2 becoming loose due to vibrations, etc., during transport of the load, causing the load to collapse.

[0065] Summary Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment and can be modified in various ways. For example, the inlet hole 11f as the "inlet" and the outlet hole 11g as the "outlet" are not necessarily limited to "holes". As long as the "inlet" and "outlet" can guide the load-tightening rope R2, the "inlet" and "outlet" can be formed by, for example, a groove having a U-shaped cross section. In addition, a toggle spring may be attached to the support shaft 12b1 of the lock lever 12b, and the lock lever 12b may be biased to the locked state and the free state by the toggle spring. This allows the toggle lever 12 to be reliably held in the locked state and the free state. [Explanation of symbols]
