[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-120322 Summary of the Invention [Problem to be solved by the invention]
[0004] The cargo compartment of a truck or the like is located at a relatively high position relative to the road surface, etc. Therefore, when a worker enters or leaves the cargo compartment, the worker must climb up and down from the cargo compartment. This climbing up and down from the cargo compartment is a burden for the worker. [Means for solving the problem]
[0005] Next, various aspects of handrails that solve the above problems will be described. (Aspect 1) A handrail comprising a base, a hanging device, and a gripping member, wherein a plurality of the hanging devices are fixed to the base at intervals, the hanging devices can be hooked into hanging holes of a lashing rail fixed to the wall of the cargo compartment, and the plurality of hanging devices are hooked into a plurality of the hanging holes formed at intervals along the extension direction of the lashing rail, and the gripping member is gripped when a worker enters or exits the cargo compartment, and is fixed so that it cannot be displaced relative to the base.
[0006] According to the above configuration, a plurality of hooking devices fixed to the handrail base are hooked into a plurality of hooking holes in the lashing rail fixed to the wall surface of the luggage compartment. This allows the handrail to be attached to the wall surface of the luggage compartment. A gripping member is fixed to the handrail base. Therefore, even if the luggage compartment is located relatively high above the road surface, a worker can climb up and down the luggage compartment while holding the gripping member of the handrail. As a result, the worker can easily enter and exit the luggage compartment. This reduces the burden on the worker when entering and exiting the luggage compartment. Furthermore, the gripping member is fixed to the base so as not to move, and the plurality of hooking devices on the base are hooked into a plurality of hooking holes in the lashing rail. This prevents the handrail attached to the wall surface of the luggage compartment from becoming unstable even if a force is applied to the gripping member when a worker holds the gripping member of the handrail to enter or exit the luggage compartment.
[0007] (Aspect 2) A handrail as described in (Aspect 1) in which, when a plurality of the hanging devices are hooked onto a plurality of the hanging holes in the lashing rail, the upper end of the gripping member is positioned above the upper end of the base.
[0008] According to the above configuration, the gripping member of the handrail protrudes above the base, making it easier for the worker to grasp the gripping member with his or her hand when descending from the luggage compartment to the road surface. (Aspect 3) A handrail described in (Aspect 1) or (Aspect 2), wherein the gripping member is formed so as to extend vertically next to the base when multiple hanging devices are hung on multiple hanging holes in the lashing rail.
[0009] According to the above configuration, since the gripping member extends beside the base, it is possible to fix the gripping member to the base at multiple points spaced apart in the direction of extension of the gripping member. By fixing the gripping member to the base in this manner, the fixation can be made highly stable.
[0010] (Aspect 4) The handrail according to (Aspect 3), wherein the gripping member is fixed to the base by a plurality of support members spaced apart in the direction in which the gripping member extends.
[0011] According to the above configuration, the gripping member is fixed to the base by a plurality of support members, thereby providing a high level of stability. Furthermore, the support members ensure a certain distance between the base and the gripping member, making it easier for an operator to grasp the gripping member with their hands.
[0012] (Aspect 5) A handrail described in any one of (Aspect 1) to (Aspect 4), in which the hanging device can be hung upside down in the hanging hole of the lashing rail, and is fixed to the base closer to one end in the vertical direction than the vertical center of the base.
[0013] According to the above configuration, the handrail can be attached to the wall of the luggage compartment upside down by hanging the handrail hanging device upside down in the hanging hole of the lashing rail fixed to the wall of the luggage compartment. By attaching the handrail to the wall of the luggage compartment upside down in this way, the vertical position of the gripping member on the handrail can be adjusted.

[Figure 6] FIG. 4 is a side view showing the lashing grip of FIG. 3. DETAILED DESCRIPTION OF THE INVENTION
[0015] An embodiment of the handrail will be described below with reference to FIGS. As shown in FIG. 1, a lashing rail 13 is fixed to a wall surface 12 of a cargo compartment 11 of a truck or the like. The wall surface 12 to which the lashing rail 13 is fixed may be an opposing wall surface connected to the entrance / exit of the cargo compartment 11. The lashing rail 13 extends horizontally, reaching close to the entrance / exit of the cargo compartment 11. A large number of hanging holes 13a are formed in the lashing rail 13 at equal intervals in the extension direction of the lashing rail 13. The hanging holes 13a are formed elongated and extend vertically.
[0016] As shown in Fig. 2, lashing grips 14 are removably attached to the hook holes 13a of the lashing rail 13. The lashing grips 14 function as handrails that workers can hold onto when entering or exiting the luggage compartment 11. Workers can easily enter or exit the luggage compartment 11 by holding the lashing grips 14 in their hands while climbing up or down from the luggage compartment 11.
[0017] <Details of Lashing Grip 14> As shown in Figures 3 to 5, the lashing grip 14 includes a base 15, a hanging device 16, and a gripping member 17. The base 15 is formed in the shape of a square plate. A plurality of hanging devices 16 are fixed to the back surface of the base 15. In this example, two hanging devices 16 are fixed to the base 15. These hanging devices 16 can be hooked onto any separate hanging holes 13a of the lashing rail 13 shown in Figures 1 and 2. The gripping member 17 is grasped when an operator enters or exits the luggage compartment 11, and is fixed so as not to be displaced relative to the surface of the base 15.
[0018] The gripping member 17 is formed in the shape of a rod extending in a straight line. The gripping member 17 is formed so as to extend in the vertical direction beside the base 15 when the plurality of hanging devices 16 are hooked into the plurality of hanging holes 13a in the lashing rail 13. When the plurality of hanging devices 16 are hooked into the plurality of hanging holes 13a in the lashing rail 13, the upper end of the gripping member 17 is positioned higher than the upper end of the base 15.
[0019] As shown in FIGS. 3 to 5, the gripping member 17 is fixed to the base 15 by a plurality of support members 18 spaced apart in the direction in which the gripping member 17 extends. More specifically, the gripping member 17 passes through the plurality of support members 18 and is fixed to these support members 18. Each of the plurality of support members 18 is fastened to the base 15 by two bolts 19. The two bolts 19 are arranged to sandwich the latch 16 on the base 15. The gripping member 17 is fixed to the base 15 via the support members 18 by fastening the support members 18 to the base 15 with the bolts 19. A certain distance is ensured between the gripping member 17 and the base 15 by the plurality of support members 18.
[0020] 6, the hook 16 is fixed to the base 15 closer to one end in the vertical direction than the center of the base 15, that is, closer to the upper end in the example of Fig. 6. The hook 16 includes a main body 21, an operating piece 22, a shaft 23, and a torsion spring 24.
[0021] The main body 21 is formed in the shape of a rectangular tube extending in the vertical direction in Figure 6. The main body 21 has a notch 25 formed in the upper end face that recesses downward, and a notch 26 formed in the lower end face that recesses upward. The operation piece 22 is disposed inside the main body 21. The operation piece 22 extends in the vertical direction in Figure 6. The shaft 23 extends in a direction perpendicular to the plane of the paper in Figure 6, penetrating the operation piece 22. The operation piece 22 is rotatable around the center line of the shaft 23.
[0022] The operation piece 22 is biased by the torsion spring 24 in a direction rotating clockwise in FIG. 6 around the center line of the shaft 23. A shoulder 27 that protrudes in the biasing direction of the torsion spring 24 is formed in a location of the operation piece 22 corresponding to the notch 25. A portion of the shoulder 27 overlaps with the notch 25, and another portion of the shoulder 27 is positioned offset from the notch 25. Furthermore, when the operation piece 22 is rotated against the biasing force of the torsion spring 24, that is, when the operation piece 22 is rotated counterclockwise in FIG. 6 around the center line of the shaft 23, the entire shoulder 27 is positioned offset from the notch 25.
[0023] <Attaching and removing the lashing grip 14 to the lashing rail 13> When attaching the lashing grip 14 to the lashing rail 13, the operating piece 22 is rotated around the center line of the shaft 23 against the biasing force of the torsion spring 24. Then, the lashing grip 14 is moved relative to the lashing rail 13 so that the upper end of the hanging hole 13a of the lashing rail 13 is inserted into the notch 25 located at the upper end of the main body 21. Furthermore, the lashing grip 14 is moved relative to the lashing rail 13 so that the notch 26 located at the lower end of the main body 21 is positioned above the lower end of the hanging hole 13a of the lashing rail 13.
[0024] In this state, by moving the lashing grip 14 downward relative to the lashing rail 13, the lower end of the hanging hole 13a in the lashing rail 13 is inserted into the notch 26 in the main body 21. At this time, the shoulder 27 of the operating piece 22 is positioned lower than the upper end of the hanging hole 13a. Therefore, when the operating piece 22 rotates due to the biasing force of the torsion spring 24, the shoulder 27 of the operating piece 22 comes into contact with the upper end of the hanging hole 13a and moves below the upper end. As a result, the shoulder 27 of the operating piece 22 and the bottom of the notch 26 in the main body 21 come into contact with the upper and lower ends of the hanging hole 13a in the lashing rail 13. In addition, the hanging device 16 attached to the hanging hole 13a can be removed from the hanging hole 13a by performing the reverse procedure of the attachment procedure of the hanging device 16 to the hanging hole 13a.
[0025] The lashing grip 14 is fixed to the lashing rail 13 by attaching a plurality of fasteners 16 to a plurality of fastening holes 13a of the lashing rail 13. The fasteners 16 of the lashing grip 14 can be attached to the fastening holes 13a of the lashing rail 13 even when the lashing grip 14 is turned upside down from the position shown in FIG. 6. Therefore, the lashing grip 14 can be fixed to the lashing rail 13 even when the lashing grip 14 is turned upside down from the position shown in FIG. 6. Furthermore, the lashing grip 14 fixed to the lashing rail 13 can be released from the above-mentioned fixation by removing the plurality of fasteners 16 from the plurality of fastening holes 13a. The lashing grip 14 released from the fixation in this way can be removed from the lashing rail 13.
[0026] <Effects of Lashing Grip 14> (1) A plurality of hanging devices 16 fixed to the base 15 of the lashing grip 14 are hooked into a plurality of hanging holes 13a in the lashing rail 13 fixed to the wall surface 12 of the luggage compartment 11. In this way, the lashing grip 14 is attached to the wall surface 12 of the luggage compartment 11. A gripping member 17 is fixed to the base 15 of the lashing grip 14. Therefore, even if the luggage compartment 11 is located relatively high above the road surface, a worker can climb up to or descend from the luggage compartment 11 while holding the gripping member 17 of the lashing grip 14 in his or her hands. As a result, the worker can easily enter and exit the luggage compartment 11. Therefore, the burden on the worker when entering and exiting the luggage compartment 11 can be reduced. Furthermore, the gripping member 17 is fixed so as not to be displaced relative to the base 15, and the plurality of hanging devices 16 on the base 15 are hooked into the plurality of hanging holes 13a in the lashing rail 13. This prevents the lashing grip 14 attached to the wall surface 12 of the cargo room 11 from becoming unstable even if a force is applied to the grip member 17 when a worker holds the grip member 17 of the lashing grip 14 and goes in or out of the cargo room 11.
[0027] (2) Since the gripping member 17 of the lashing grip 14 protrudes above the base 15, it is easy for the worker to grasp the gripping member 17 with his / her hand when getting out of the luggage compartment 11. (3) Because the gripping member 17 extends beside the base 15, it is possible to fix the gripping member 17 to the base 15 at multiple locations spaced apart in the direction in which the gripping member 17 extends. Fixing the gripping member 17 to the base 15 in this manner makes it possible to achieve a highly stable fixation.
[0028] (4) The gripping member 17 is fixed to the base 15 by a plurality of support members 18 spaced apart in the direction in which the gripping member 17 extends. This allows the gripping member 17 to be fixed to the base 15 with high stability. Furthermore, the support members 18 ensure a certain distance between the base 15 and the gripping member 17, making it easier for an operator to grasp the gripping member 17 with their hands.
[0029] (5) The hanging device 16 is fixed to the base 15 closer to the upper end than the center in the vertical direction of the base 15. Furthermore, the hanging device 16 can be attached to the hanging hole 13a of the lashing rail 13 even when the hanging device 16 is turned upside down. Therefore, by turning the hanging device 16 of the lashing grip 14 upside down and hooking it into the hanging hole 13a of the lashing rail 13 fixed to the wall surface 12 of the luggage compartment 11, the lashing grip 14 can be attached upside down to the wall of the luggage compartment 11. By turning the lashing grip 14 upside down and attaching it to the wall surface 12 of the luggage compartment 11 in this way, the vertical position of the gripping member 17 of the lashing grip 14 can be adjusted.
[0030] The above embodiment can be modified as follows, for example: The above embodiment and the following modifications can be combined and implemented within the scope of technical compatibility. The hook 16 may be fixed to the base 15 closer to the lower end than to the center of the base 15 in the vertical direction.
[0031] The fastener 16 of the lashing grip 14 does not necessarily have to be capable of being attached to the fastener hole 13a of the lashing rail 13 upside down. The gripping member 17 does not necessarily have to be fixed to the base 15 at multiple points.
[0032] The upper end of the gripping member 17 does not necessarily have to be located above the upper end of the base 15 . The gripping member 17 does not necessarily have to be positioned so as to extend along the side of the base 15. The gripping member 17 does not necessarily have to extend vertically.
[0033] The lashing rail 13 may be fixed to the wall of a cargo compartment other than the cargo compartment 11 of the truck. [Explanation of symbols]
