Description

DETAILED DESCRIPTION OF THE INVENTION (Technical field to which the present invention pertains) The present invention relates to a hook structure for hooking a rope for fixing a load on a truck bed and a rope hooking device using the hook.

(Prior Art) Various types of rope hooking devices and rope hooking devices using the hooks have been proposed in the past, and typical ones are shown in FIGS. 5 and 6, for example. There is something like that shown in

That is, in the conventional structure shown in FIG. 5, a ring-shaped portion 55 is formed by attaching a rope hooking hook 51 formed in a substantially inverted U-shape to a frame 53 of a carrier 52. It is designed to be hooked through a rope 54 inside 55.

Next, the conventional structure shown in FIG. 6 has a short locking arm portion 56 protruding downward, and has a substantially collapsed shape with an intermediate portion.
It has a hook 57 for hooking a rope formed in a letter shape, and the hook 57 for hooking the rope is attached to the frame 53 of the carrier 52 to form a ring-shaped portion 58. When the rope 54 is to be hung, the rope 54 is hung on the locking leg portion 56 or, similarly to the structure shown in FIG. It has become.

Note that the rope hooks 51 and 57 of the conventional structure shown in FIGS. 5 and 6 are both formed so as to protrude straight upward from the frame 53.

On the other hand, a rope hook having the structure shown in FIGS. 7 and 8 and a rope hook device using the same are also known.

That is, the hook 80 for hooking the rope is composed of a horizontal portion 81, two legs 82 hanging from both ends of the horizontal portion, and a key portion for locking which is formed at the lower end of the two legs 82. It consists of 83. The two leg portions 82 are bent in a direction away from the side fan plate 85 as going from the key portion 83 to the horizontal portion 81. The two legs 82 are inserted into through holes 87 formed in the frame 86 of the truck carrier, and are prevented from falling off by the key portions 83. The end of the rope 84 is wrapped around the horizontal portion 81 and latched.

(Problem to be solved by the invention) However, in the conventional structure shown in FIG.
Since the hook 54 must be hooked by passing it through the ring-shaped portion 55, there is a problem that easy hooking / unhooking cannot be performed and workability is poor.

Further, in the conventional structure shown in FIG. 6, when the rope 54 is hung on the locking leg 56, the rope 54 can be hung with one touch, thereby improving workability. Since only the book is formed in a protruding state, and the rope 54 is hung on the locking arm 56, the strength is weak and the reliability is poor.

Further, as a problem common to the conventional structures shown in FIG. 5 and FIG. 6, in these conventional structures, both the hooks 51 and 57 for locking the rope are projected from the frame 53 straight upward. Since the hooks 51 and 57 for hooking the ropes are moved outward, the work of hooking and unhooking the ropes 54 becomes difficult, and the workability deteriorates. For this reason, since the rope hooks 51 and 57 must be provided close to the inside of the carrier 52, the rope hooks 51 and 57 are in the way,
There was a problem that the cargo space was narrowed.

In addition, there are no special means on the left and right side surfaces of the rope hooks 51 and 57 to make it easy for the worker or the like to grasp it by hand. With a structure in which the hooks 51 and 57 for holding the rope are sunk, it is difficult to grasp by hand at the time of use, so there is a problem that the pull-out work is not easy and the workability is poor.

On the other hand, in the hook 80 for hooking the rope having the structure shown in FIGS. 7 and 8 and the rope hooking device using the same, since the leg 82 is bent in a direction away from the side fan plate 85, Some of the drawbacks are eliminated, but on the other hand, when the hook 80 for hooking the rope is sunk when not in use, the hook 80
Is difficult to grasp by hand, and the work of retaining the rope 84 is time-consuming.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object the structure of a hook for hooking a rope on a truck bed, which can improve the workability of hooking and unhooking a rope, and the hook. An object of the present invention is to provide a device for retaining a rope using the same.

(Embodiments of the invention) Hereinafter, embodiments of the invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic perspective view of a truck bed to which one embodiment of the present invention is applied, and FIG. 2 is an enlarged perspective view of a portion C in FIG.

In the figure, a bed 1 of this truck is composed of a plurality of floorboards 2.
And a frame 3 surrounding the outside of the plurality of floorboards 2,
In addition, a side flap 4 is provided on each of the left and right sides, and a rear panel unit 6 having two doors 5 which are double-opened at the rear is provided. In addition, a plurality of rope hooks 7 are provided in the frame 3 on both left and right sides of the truck bed 1 scattered in the front-rear direction, and the load 8 of the bed 1 is fixed to the rope hooks 7. The rope 20 can be hooked.

The detailed structure of the rope retaining device having the rope retaining hook 7 for retaining the rope 20 is further shown in FIG. 3 and FIG.

Therefore, the detailed structure will be described with reference to FIGS. 3 and 4. The frame 3 is formed to have a substantially inverted L-shaped cross section integrally with the side surface 31 and the upper surface 32. Also, frame 3
In the upper surface 32, the inner part 33 is formed one step higher than the outer part 34, and the lower part 34 is formed with a through hole 9 for attaching the rope hook 7. . In addition, two through holes 9 are formed for each one rope hooking hook 7 so as to be separated from each other in the front-rear direction. Further, a square pipe 10 having a rectangular horizontal cross section and having open upper and lower surfaces is disposed on the back side of the frame 3. This square pipe 10 has a pair of through holes 9,
The opening is made to correspond to a portion where the hook 7 for attaching the rope hook 9 is attached, and each portion is provided by being welded and fixed. Also this square pipe 10
On the left and right inside surfaces, there is a sheet-like sponge
11 is bonded and fixed via an adhesive.

Next, the rope hook 7 is a forged product,
71, a pair of left and right legs 72 projecting downward from the lower surface of the horizontal portion 71, and a rope hooking protrusion formed on each of the left and right sides of the pair of left and right legs 72. And a locking portion 73 protruding downward from the base end of the protruding portion 76. Note that the locking portion 73 is formed shorter than the leg portion 72. Then, by forming the locking portion 73, the locking portion 73 and the leg 72
The recesses 12 for hooking the rope 20 are provided on the lower surface of the protruding portion 76 between them. The left and right side surfaces 77 (see FIG. 3) of each locking portion 73 are formed so as to be inclined inward toward the frame 3 side. It is easier to grasp.

On the other hand, the pair of leg portions 72 respectively correspond to the through holes 9 of the frame body 3, and are inserted and disposed so as to have a play between the through holes 9 and to be vertically slidable. The outer diameter of each leg 72 is formed smaller than the inner diameter of the through hole 9. Furthermore, a screw 13 is attached to the lower end 74 of each leg 72.
Are formed, and the upper end portion 75 between the lower end portion 74 and the horizontal portion 71 is formed in an inclined state. The hook 7 for hooking the rope is inserted into the through hole 9 from the lower end portion 74 side, and can be retracted and stored until the horizontal portion 71 comes into contact with the upper surface 32 of the frame body 3. In the square pipe 10 on the back side, the nut 13 is screwed to the nut 13 with the screw 13 at the lower end 74, thereby preventing the nut 13 from coming off. In this case, as shown in the drawing, the leg 72 is arranged in such a direction that the upper end 75 is bent away from the side fan plate 4 as it goes from the lower end 74 to the horizontal part 71 side. After the nut 14 is screwed into the screw 13, the square pipe 10
Is closed by the blind plate 15.

In the truck bed 1 configured as described above, when the rope hook 7 is not used, FIG.
As shown by, the horizontal portion 71 can be pushed down (in the direction of arrow D in FIG. 3) and stored in the frame 3 until it contacts the upper surface 32 of the frame 3. At this time, the upper surface of the horizontal portion 71 is a part of the frame 3
It is stored and held in a state where the height is substantially the same as that of. Also, when the vehicle is run in this state and the rope hook 7 swings largely left and right and comes into contact with the inner surface of the square pipe 10,
Since the sheet-like sponge 11 is adhered to the inner surface of the square pipe 10, the sheet-like sponge 11 is interfered by the sponge 11, and it is possible to suppress the pressing sound due to the interference.

On the other hand, when the rope hook 7 is used, the side surfaces 77 of the left and right protrusions 76 are pinched by a finger and lifted in the direction of arrow U in FIG. Pull out until regulated. Then, as shown in FIG. 2, when the rope 20 is hung from the outside through the pair of leg portions 72 and through the lower surfaces of the left and right protruding portions 76, that is, the inside of the concave portion 12, it can be latched with almost one touch. . If necessary, a pair of legs 72 and a horizontal portion
It can also be hooked through the inside of the ring-shaped portion 21 formed by 71 and. In addition, since the backlash is positively provided between the pair of leg portions 72 and the through-hole 9, when the rope 20 is hooked, the hook 7 is used to hold the rope. Of the rope 20 and the hook 7 for retaining the rope
The rope 20 holds the luggage firmly and securely.

Therefore, in the above-described rope-holding structure of the truck bed, (1) since the side surface 77 of the protruding portion 76 is inclined inward toward the frame 3 side, the rope-holding hook is used when not in use. Even in the type in which the submersible 7 is sunk into the frame 3, the inclined side surface 77 can be grasped by hand, so that the rope hook 7 can be easily pulled out.

(2) The rope 20 is hooked by turning the rope 20 from outside to the protrusion 76 for hanging the rope 20 formed on each of the left and right sides of the pair of legs 72. The workability is improved because it can be easily attached.

(3) By hanging the rope 20 on the two right and left protrusions 76, the tensile force received from the rope 20 is distributed to the two protrusions 76, so that strength is obtained and reliability is improved. improves.

(4) Since the pair of leg portions 72 holding the horizontal portion 71 on which the two projecting portions 76 are formed is provided, the strength of the leg portion 72 itself is obtained, and the reliability is improved.

(5) The leg 72 is bent in a direction away from the side tilt plate 4 of the carrier as it goes from the lower end portion 74 to the horizontal portion 71 side. Therefore, even when the side tilt plate 4 is upright, the side tilt plate is provided. Since the gap between the horizontal portion 4 and the horizontal portion 71, that is, the portion indicated by the symbol L in FIG. 4 (B), can be largely obtained, the rope 20 can be easily hooked and unhooked with the side tilt plate 4 standing. And workability can be improved.

(6) When not in use, the hook 7 for hooking the rope is sunk into the frame 3 until the horizontal portion 71 comes into contact with the upper surface 32 of the frame 3, and is stored. Since it can be used, it is not disturbed when not in use, and the practicality is improved.

(7) If a structure in which rattling is provided between the pair of leg portions 72 and the through hole 9 is provided positively, when the rope 20 is latched,
Is tilted in the direction in which the rope 20 is pulled by the rope 20, so that the rope 20 and the hook 7 for hooking the rope are adapted, and the rope 20 can securely hold the load.

Although the present invention has been described with reference to the above-described embodiment, it is needless to say that the present invention is not limited to the structure of this embodiment, and various design changes may be made without departing from the gist of the present invention. . For example, in the above embodiment, the structure in which the locking portion 73 protruding from the tip of the protruding portion 76 to a lower side than the leg portion 72 is disclosed, but the locking portion 73 is not necessarily provided. Is also good.

(Effects of the invention) As described above, according to the structure for retaining the rope of the truck bed according to the present invention, the workability of retaining and removing the rope is improved, and the retaining strength is obtained and the reliability is improved.
