Description

TECHNICAL FIELD The present invention relates to a structure for tightening a wire rope, a chain or the like when an automobile is carried by a ship, a train, a vehicle or the like.

2. Description of the Related Art A wire rope or the like for performing tightening for transportation has been engaged with a hook called a tie-down hook attached to a body frame, for example. In order to attach this tie-down hook, a special reinforced structure had to be provided on the body frame.

On the other hand, instead of such a tie down hook,
It is also conceivable to use a bracket for towing the car. The bracket 1 is provided on the rear side of the vehicle body shown in FIG. 5, and is attached to the body frame 3 by a bolt nut 2 (or welding) as shown in FIG.
A hole 4 for engaging a wire rope or the like is formed at the tip. The position of this hole 4 is provided at the tip of the bracket 1 extending downwardly of the vehicle body in order to avoid the bumper 5 existing at the rear of the vehicle body. Therefore, the bracket 1 has a large offset dimension L between the bolt nut 2 and the hole 4.

However, due to the offset dimension L, a large moment acts during towing in the conventional bracket 1, and the body frame 3 must be reinforced in order to withstand this moment. Further, there are wire ropes and the like used for transporting an automobile that extend from the center side of the vehicle body and engage with the body frame. In this case, the engaging portion is provided on the center side of the vehicle body. Is desirable.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a wire-type vehicle body binding structure in which a large moment does not act during towing and an engaging portion can be present on the vehicle body center side as well. And

Means for Solving the Problems The present invention has been made in order to achieve the above-mentioned object, and a permanent wire having an engaging portion at its tip is attached to a body frame at the rear of a vehicle body. It is tied to the rear of the vehicle body and the front end side is detachably locked to a metal fitting on the center side of the vehicle body, and the metal fitting has a structure that can be locked even in the middle of a standing wire and a strength that can withstand the load for binding the vehicle body. An opening is provided in the bumper at a horizontal rear position with respect to the attachment of the permanent wire.

Action When towing an automobile, the permanent wire is removed from the metal fittings and horizontally extended rearward, and the engaging portion at the tip is passed through the opening of the bumper to engage with the counterpart wire rope or the like. By providing the bumper with an opening, there is no offset dimension for avoiding the bumper, and a large moment is not generated during towing.

Further, during transportation, it is also possible to lock the middle portion of the standing wire with a metal fitting so that the engaging portion at the tip is positioned on the center side of the vehicle body.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a view corresponding to FIG. 6 of a conventional example, FIG. 2 is a II-II sectional view of FIG. 1, and FIG. 3 is a III-III sectional view of FIG. The same parts as those in the conventional art are designated by the same reference numerals.

On the body frame 3 at the rear of the vehicle body, there are provided a rear side member 6 arranged on both sides of the vehicle body in the front-rear direction, and a rear end cross member 7 connected to the pair of rear side members 6 and arranged on the rear end of the vehicle in the left-right direction. is there. The standing wire 8 of this embodiment is attached to the rear side member 6. At the rear end of the rear side member 6, a closed first metal fitting 9 is welded as shown in FIG.
A second hook-shaped second metal fitting 10 is welded to the front side of the vehicle body with respect to the metal fitting 9. 1 at both ends of the permanent wire 8
1, 12 are formed, and the wheel at the rear end is connected to the first metal fitting 9 and is rotatable. The ring 12 at the tip is adapted to be locked to the second metal fitting 10 as shown by a chain double-dashed line in FIG. 1 when the standing wire 8 is not used. Further, since the second metal fitting 10 has a hook shape, it can be locked even in the middle of the standing wire 8. Furthermore, the strength of the second metal fitting 10 is such that even when a large load is input due to shaking during transportation, the vehicle body is tightened while the middle of the standing wire 8 is locked to the second metal fitting 10. Like the metal fitting 9, it is sufficiently durable.

Therefore, the first and second fittings 9 and 10 have sufficient strength. For the first metal fitting 9 to which the rear end of the permanent wire 8 is tied,
The bumper 5 in the horizontal rear position is provided with an opening 13. The size of this opening 13 is such that the shaft 12 of the permanent wire 8 can pass through it sufficiently, and is normally closed by a plug 14.

The operation of this embodiment will be described below. Standing wire 8
When pulling with the use of, the plug 14 is removed from the opening 13 as shown in FIG. 4, and the loop 12 at the tip of the standing wire 8 removed from the second metal fitting 10 is passed through the opening 13 of the bumper 5, Engages with the mating wire rope or chain hook.

When tightening to carry an automobile by ship, train, vehicle, etc., place the tip of the standing wire 8 in the second position.
The metal body 10 is removed, and the wheel 12 is directly engaged with the tightening device on the carrying side to fix the vehicle body. Alternatively, depending on the positional relationship with the tightening device on the carrying side, the middle of the standing wire 8 may be replaced by the second metal fitting 10.
It is also possible to lock the position (indicated by the alternate long and short dash line in FIG. 1) on the vehicle body and move the fixed position to the center side of the vehicle body for tightening, which is convenient when pulling to the center side of the vehicle body for tightening. In this state, even if the wire rope for tightening or the hook of the chain is engaged with the wheel 12, the first and second metal fittings 9 and 10 have sufficient strength, so that even if a large load is input during transportation. It does not cause any inconvenience.

In this way, the vehicle can be towed and transported by using the single standing wire 8.

Although the plug 14 can be completely removed from the opening 13 in the above-described embodiments, in other embodiments, the plug 14 is retained in the opening 13 even after being removed, and the plug 14 is lost. It is also possible not to. Although the first metal fitting 9 and the second metal fitting 10 are welded to the rear side member 6, they may be welded to other body frames in other embodiments. Further, although the engaging portion of the permanent wire is the loop 12 at the tip, in other embodiments, a fitting for engagement may be attached to the tip of the wire 8. Further, in the present embodiment, the rear end of the standing wire 8 is tied to the first metal fitting 9, but in another embodiment 4, another metal fitting is provided at the rear end of the standing wire 8 and the other metal fitting is used. The other metal fitting may be attached to the first metal fitting 9 so as to be detachable from the first metal fitting 9.

Effect of the Invention As described above, according to the wire-type vehicle body tightening structure of the present invention, it is possible to perform the tightening for the towing of the vehicle and the transportation of the vehicle by using the single standing wire. At the time of towing, by removing the tip side of the standing wire from the metal fitting and extending it rearward through the opening of the bumper, it is possible to easily engage with the wire rope of the mating side. At this time, since there is no offset dimension for avoiding the bumper as in the conventional case, a large moment based on the offset dimension can be prevented from occurring. Therefore, since the reinforcement applied to the body frame is small, the vehicle body characteristic is not adversely affected even in the case of a manga collision. In addition, when tightening during transportation, it is possible to lock the metal part in the middle of the standing wire and position the engaging part of the tip of the standing wire at the center of the vehicle body. It can be easily engaged in accordance with the positional relationship with.
