Abstract

PURPOSE:To facilitate engagement and disengagement of a tie-down hook with and from a hook hole, by a method wherein the upper flange of a bracket for tightening is secured to the bottom of a side member, and the hook hole for the tie-down hook is formed in the bottom wall of the bracket. CONSTITUTION:A bracket 4A for tightening formed in a cup-shape is provided at its upper part with an upper flange 4b bent about at right angles. The upper flange 4b is inserted through a bottom opening 3, formed in a bottom wall 1b of a rear side member 1, into the internal space of the rear side member 1 and is spot-welded to the upper surface of the bottom 1b. Thus, a bottom wall 4c of the bracket 4A is positioned in a level enoughly lower than that of the bottom wall 1b of the rear side member 1. A book hole 6, adapted to be engaged with a tie-down hook 5, is formed in the central part of the bottom wall 4c. This enables engagement and disengagement of the tie-down hook with and from the hook hole through slight insertion of a hand into a portion below a side will 2 when the hook 5 is engaged and disengaged with and from the hook hole 6.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an automobile body structure, and more particularly to a structure for securing a tightening bracket for hooking a tie-down hook for tightening a vehicle body.

-Prior Art- As is well known, when transporting a car as shown in Fig. 3, it is necessary to tighten the car body to the body of a ship, carrier car, etc. using tie-down hooks. A conventional tightening bracket to be hooked is normally arranged on the vehicle body in a state as shown in FIG. That is, FIG. 4 is a sectional view taken along the TV-TV line in FIG.
Reference numeral l in FIG. 4 is a rear side member having m flanges la fixed to a side sill 2 extending in the front-rear direction of the vehicle body, and a bottom opening 3 formed in the bottom wall ib of the side member l has a disk-like shape. The tightening bracket 4 is fixed. This tightening bracket 4 has a hooking hole 6 formed in the center of its surface into which a tie-down hook 5 shown by a phantom line can be hooked, and reinforcing ribs 4a are bent and formed on the outer periphery of the hooking hole 6. Therefore, in such a structure for picking up the tightening bracket 4, the tie-down hook 5 is held in the hooking hole 6 in the state shown in the figure during transportation of the automobile, but the hooking hole 6 of the tightening bracket 4 is held in the state shown in the figure. Since it is located at approximately the same height as the bottom wall 1b of the rear side member L, it is necessary to reach deep into the lower part of the vehicle body to insert the tie-down hook 5 into the hook hole 6, making attachment and detachment of the tie-down hook 5 troublesome. . Also, near the tightening bracket 4, there is a suspension bracket A, etc., which is schematically indicated by a phantom line, so
If the tie-down hook 5 interferes with the suspension bracket A or the like, it may not be possible to provide the tightening portion at an effective position. In addition, the reference numeral 7 in FIG. 4 is a rear side member reinforcement arranged inside the rear side member l.
538).

1. Object of the Invention 1. An object of the present invention is to enable a tie-down hook to be easily engaged with a tightening bracket in view of the current state of the conventional tightening bracket mounting structure as described above. The purpose is to obtain a structure that does not pose any risk of interfering with the

Structure of the Invention In order to achieve this object, the present invention provides a tightening bracket fixed to the bottom opening of a side member whose side is fixed to the inside of a side sill, in which two parts of the "cup" shaped tightening bracket are provided. A flange is inserted into the bottom opening and fixed to the bottom wall of the side member, and a hook hole through which a tie-down hook can be hooked is formed on the bottom wall of the tightening bracket located on the F side of the side member. This is what I propose.

-Example- Hereinafter, details of an example of the present invention will be explained with reference to FIGS. 1 and 2.

FIG. 1 is a sectional view corresponding to FIG. 4 of the first embodiment of the present invention, and the same structural parts as in FIG. 4 are designated by the same reference numerals. The feature of the first embodiment is the tightening bracket 4A formed into a "cup" shape.
The top 7 langes 4b are partially bent at a right angle.
have. This -1 partial flange 4b is inserted into the internal space of the rear side member l through the bottom opening 3 formed in the bottom wall 1b of the rear side member l, and is spot welded to the bottom wall 1b-H surface of the rear side member l. Ru. Therefore, when the tightening bracket 4A is assembled to the rear side member l, the bottom wall 4C of the tightening bracket 4A is
is located at a position sufficiently lower than the bottom wall ib of the rear side member 1, and a hooking hole 6 into which the tie-down hook 5 can be hooked is formed in the center of the open bottom v4c. In addition, in the illustrated example, in order to stabilize the fixed state of the tightening bracket 4A, 7 langes 4d are provided on the side sill opposing portion of the bottom wall 4C.
It is folded up and joined to the lower flange 2a of the side sill 2.

Since the first embodiment has the structure as described below, the hook hole 6 formed in the bottom wall 4c of the tightening bracket 4A is located at a sufficiently lower position than the bottom wall b of the rear side member l. When attaching and detaching the tie-down hook 5 to the thinning hole 6, the tie-down hook 5 can be attached and detached by simply inserting a hand slightly below the side sill 2.

In addition, the tie-down hook 5 engaged with the tensioning bracket) 4A is separated from the suspension bracket A near the tensioning bracket) 4A, so the tie-down hook 5 is connected to the suspension bracket A). The tie-down hooks 5 can effectively tighten the vehicle body without any interference from the tie-down hooks 5.

FIG. 2 is a sectional view corresponding to FIG. 1 of a tightening bracket mounting structure according to a second embodiment of the present invention, and the tightening bracket 4B in this embodiment is characterized in that it also serves as a jack-up point. That is, the tightening bracket 4
A jack up point part 4e projecting downward is integrally molded on the side sill opposing part of the bottom wall 4C of B, and the flange 4f near this jack up point part 4e is spotted on the lower flange 2a of the sight sill 2. Welding.

Therefore, in the configuration of this example.

In addition to the effects described in the first embodiment, since the jack up point portion 4e is firmly fixed to the side sill 2 and the rear side member l, which are strength members, the jack head B shown by the imaginary line can be moved to the jack up point portion. It has the advantage of acting on 4e to jack up the vehicle body. Although the above embodiments have been described with respect to rear side members, it goes without saying that the present invention can be similarly applied to front side members.

Effects of the Invention As is clear from the above description, according to the present invention, the hooking hole of the tightening bracket can be placed at a position sufficiently lower than the rear side member, making it easier to attach and detach the tie-down hook. This has the effect of providing a structure in which the peripheral members and tie-down hooks do not interfere with each other.
