2. Description of the Related Art In recent years, for example, the work of modifying prototype car bodies at car manufacturers and the work of repairing car bodies at car repair shops has increased dramatically.
Conventionally, when carrying out such modification and repair work on an automobile body, workers generally place the automobile body on a support stand and then crawl under it to repair or remodel the body, assemble and disassemble body accessories, etc. While performing work such as welding, the workers were forced to sit in an awkward working position lying on their backs, making it difficult to perform even small tasks and not being able to do the work efficiently and adequately in terms of time. Ta.

The present invention was developed in view of the above situation, and its purpose is to provide a supporting device for an automobile body. In order to achieve this purpose, the present invention attaches an inclined support base member to the main body column so as to be movable up and down via a gear mechanism.
A lock lever for operating a lock mechanism is provided at the end of the inclined support base material, and the inclined support base material is rotatable or unrotatable via the lock mechanism, and the tilted base material has at least two horizontally extending lock levers. The book body support bars are each independently slidably attached to the inclined support base material.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. Reference numeral 1 denotes a hollow inclined support base material which is movable up and down relative to the main body support 3 via bevel gears 2 and 2', and this inclined support base material 1 is rotatable via lock pins 4 and 4'. , it is impossible to rotate. To explain this in more detail, the second
In the figure, the main body support 3 is integrated with the bevel gear 2'.
A vertically movable piece 5 is screwed onto a gear main shaft 6 which is rotatably supported by a gear main shaft 6. A cylindrical pipe 5a is protruded from one side of the vertically movable piece 5, and the tip of the vertically movable piece 5 is connected to the main body support 3. It protrudes slightly outward. Therefore, the vertically movable piece 5 moves vertically when the gear main shaft 6 rotates. A bearing 7 is arranged at the tip of the cylindrical pipe 5a, and this bearing 7
A tilt angle plate 8 having a C-shaped cross section is fitted on the outside, and a large number of tilt angle adjustment holes 9 are provided at intervals in the circumferential direction of the cylindrical pipe 5a on the periphery thereof, as shown in FIG. (24 holes in the figure) are drilled. 1
Reference numeral 0 denotes a rotary plate back plate, and 11 a rotary plate.The shaft end of the rotary plate 11 is rotatably attached to a bearing 7 and a cylindrical pipe 5a.
The aforementioned lock pins 4, 4 pass through the lower portion, making it impossible to rotate. That is, the lock pins 4, 4 are always held in place by the main body support 3 by the coil spring 12.
It is biased toward the side by a spring, and its tip fits into any of the above-mentioned inclination angle adjustment holes 9 to be in a locked state. The inclined support base member 1 is integrally fastened to the right side of the rotary disk 11 in FIG. 2 by bolts 13, 13. With such a configuration, the inclined support base material 1 has a bevel gear 2,
It can be moved up and down via the pins 2', it can be rotated via the lock pins 4, 4, and it cannot be rotated. Note that the lock pins 4, 4 can be unlocked by pulling the lock levers 15, 15 provided on the inside of the grips 14, 14 provided at the ends of the inclined support base 1 outward, and the lock pins 4, 4 can be unlocked via the cables 16, 16. , 4 move to the right in FIG. 2 against the spring force of the coil spring 12 to release the lock.

Two sliding brackets 17, 17 each having a substantially C-shaped cross section are independently and slidably engaged with the inclined support base material 1 along the longitudinal direction of the inclined support base material 1. Further, a slide rod 18 is integrated into the upper part of the inclined support base 1 in parallel thereto, and screw-type clasps 19, 19 are attached to this slide rod 18.
It can be fixed at any position on the top. The slide brackets 17, 17 can be fixed at any position in the longitudinal direction of the inclined support base 1 by means of the clasps 19, 19. There are T-shaped mounting pieces 20, 20 on the front of the sliding brackets 17, 17.
are integrally welded, and these mounting pieces 20, 2
0, longitudinally elongated body support bars 21, 21 are integrally attached to the side surfaces thereof in parallel. Therefore, these two body support bars 21, 2
1 extend horizontally parallel to each other and are slidable along the longitudinal direction of the inclined support base 1, respectively. In addition, 22 is an operation handle for rotating the bevel gears 2, 2', 23 is a moving caster, 2
A fixed leg 4 is detachably attached to the main body support leg 3a.

FIG. 4 is an overall side view showing the actual usage state using two of these devices. In the figure, 25 is an automobile body and 26 is a bumper mounting hole.

Next, to explain how to use this device configured as described above, first, turn the operating handle 22 in one direction to place the automobile body 25 in a predetermined position.
Lower the inclined support base material 1 to the front and rear bumper mounting holes 26, 26. Next, stopper 1
Loosen 9 and 19 and remove sliding brackets 17 and 1.
7 along the longitudinal direction of the inclined support base material 1, and insert the left and right bumper mounting holes 26, 26, respectively.
The body support bars 21, 21 are positioned so that they can be inserted therethrough, and the sliding brackets 17, 17 are fixed with the stoppers 19, 19. After the body support bars 21, 21 are securely inserted and connected so that the automobile body 25 can be lifted, turn the operating handle 22 in the opposite direction to the one shown in FIG. Lift the body 25 to a desired height. Depending on the content of the work, it is of course possible to work with the car body 25 held horizontally, but if the car body 25
When tilting the vehicle body 25, adjust the tilt angle
Every 15 degrees, 15 degrees, 30 degrees, 45 degrees, ..., 345 degrees,
It can be tilted up to 360 degrees and can also be rotated in both forward and reverse directions, which is convenient. That is, by using the grips 14, 14 mentioned above, and keeping the lock levers 15, 15 pulled outward with both hands, the automobile body 25 was tilted one by one until the desired inclination that was most convenient for the work was obtained. When the lock levers 15, 15 are released, they become locked and the inclined support base 1 is fixed unrotatably. In this tilting operation, the automobile body 25 is quite heavy, so as the automobile body 25 is tilted from a horizontal position, the weight of the automobile body 25 gradually comes to rest on the worker's arm.

In this way, we handle quite heavy objects,
The tilting operation is performed by grasping the grip 14 and the lock lever 15 provided at the end of the tilted support base 1 together, so the weight is reduced and the tilted support base 1 and the main body are rotated. There is no chance of your hand getting caught between it and the support post 3. Further, especially when repairing the automobile body 25, various parts are attached to the automobile body 25, so the weight thereof becomes extremely heavy.

In such a case, it is possible to use a plurality of workers, four workers in this embodiment. In this way, the automobile body 25 can be held at a desired height and inclination, allowing the operator to work efficiently in a free working posture. Note that during the work, for added safety, the fixed legs 24 are set on the ground to fix the device so that it does not move.
Furthermore, since the main body support leg portion 3a is provided with casters 23, the automobile body 25 can be moved to any desired location while maintaining the desired height and inclination.

In the above embodiment, the body support bar is inserted and connected using the bumper mounting hole, but of course the connection method is not limited to this.

According to the present invention configured in this way, the automobile body can be held at a desired height and inclination, a free working posture is secured, and sufficient work can be carried out efficiently in a short time. In addition, since the lock lever is provided at the end of the tilted support base material, the tilting operation of the tilted support base material is easy, and there is no possibility of unexpected accidents.
It has the advantage of excellent operability. In particular, when carrying out modification and repair work on the underbody part, which has conventionally been considered the most difficult work, the workability is significantly improved and a great effect is achieved. Also,
Since at least two body support bars are attached and each can be slid independently onto the inclined support base material, it has the advantage that it can be used in a wide range of ways, regardless of the vehicle width, whether it is a large car body or a small car body. be.
