[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traction tool for restoring a damaged recess in an automobile body and a method for restoring the damaged recess by using the same.

[0002]

2. Description of the Related Art Conventionally, a tool for pulling a damaged concave portion of an automobile by the principle of "lever" at a central portion of a plate-like horizontal rod erected on two fulcrums has been developed and put to practical use. However, since the bifurcated metal fittings at the fulcrum portion are fixed to the horizontal rod, it is difficult to fit the inclined surface of the body and the setting (mounting) is difficult to stabilize, and the damaged recess is pulled by the principle of leverage. Therefore, there is a problem that it is difficult to delicately adjust the "pull-out force" and the "pull-out amount", and the restoration work cannot be performed quickly and easily.

Further, a device utilizing the inertia force of a hammer has been developed, but it requires skill in adjusting the "pull-out force" and "pull-out amount", and an accident such as pinching of a finger during operation is likely to occur. There were problems that it was difficult to operate with peace of mind and that no beginner could use it.

[0004]

According to the present invention, four support plates (foots) are stably mounted (set) on the inclined surface of the body, and the "drawing force" and "drawing amount" of the damaged recess are delicate. To provide a repair tool for repairing a damaged body part of a vehicle with a high degree of safety, while maintaining the tool safely even when the tractive force of the recess is lost by performing adjustment work quickly and easily, and providing a repair method. With the goal.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A tubular section 1 "is formed at one end of a plate-like horizontal rod 1 having a rectangular vertical section in the width direction (vertical direction) of the horizontal rod 1.
The vertical leg 2 by the screw rod 2 ′ is inserted into the cylindrical portion 1 ″ and the cylindrical portion 1 ″
The female screw 2 ", 2" (nut) is screwed into the screw 2 'in contact with both ends of the screw 2', and the screw 2 'is screwed into the female screw 2 ", 2".
Can be rotated forward and backward to extend and contract the vertical leg 2 in the direction of its tip (vertical direction b).

The other end of the horizontal rod 1 is slidably fitted into a rectangular through hole 2a 'formed in a direction perpendicular to the center line of the vertical short cylinder 2a, and a female screw 2b is inserted into the distal end of the short cylinder 2a. Is formed by screwing a male screw rod 2 ′ into the other vertical leg 2, which can be expanded and contracted in the distal direction (vertical direction b), and attached to the base end of the short vertical cylinder 2 a. The formed female screw 2b 'is attached to the butterfly screw 2
c, and the leading end thereof presses the thickness width surface 1 'of the horizontal rod 1 to stop the sliding of the short vertical cylinder 2a in the horizontal direction a.

The bearing plate 3 'is pivoted by a bearing plate 3' protruding from the center of a fork fitting 3 at the tip of each of the two vertical legs 2, 2 and a pin 3 "orthogonal to the vertical leg 2. By supporting, the fork fitting 3 is supported so as to be tiltable about the pin 3 ″.

At both ends of the bifurcated metal fitting 3, a central portion of a plate or bowl-shaped support plate 4 (foot) for supporting the horizontal rod 1 is loosely attached 4a [in all directions (universal) without being fixed. Tiltably connect]. That is, as shown in FIG.
Connecting portion 3a between two-stage heads 3b and 3c provided at both ends of
Through the large-diameter central through hole 4b of the support
Is mounted so as to be tiltable universally.

One or a plurality of towing tubes 5 for towing the damaged recess 11 of the vehicle body 8 outward are disposed vertically between the two vertical legs 2, 2, and the center of the towing tube 5 is provided on the towing tube 5. The horizontal rod 1 is slidably fitted in the center line direction (longitudinal direction) and the longitudinal direction (horizontal direction) of the horizontal rod 1 in a long hole 5a formed long in the line direction.

The horizontal rod 1 has its thickness and width faces 1 ', 1' in contact with the inner surfaces of both ends 10 ', 10' of the U-shaped slide plate 10, and the U-shaped slide plate 10 is extended in the longitudinal direction of the horizontal rod 1. Slidably in the direction (lateral direction a),
The tow tube 5 is slidably fitted in the vertical direction b in the through holes 10 "and 10" formed in the hole 0 ', thereby regulating the tow tube 5 in the vertical direction b with respect to the horizontal rod 1. The towing cylinder 5 does not tilt with respect to the horizontal rod 1.

A female screw 5 'is formed at one end of the pulling tube 5 as described above, and the male screw 5 "is screwed into the female screw 5". Presses the thickness width surface 1 'of the horizontal rod 1 through the washer 5b, thereby moving the towing cylinder 5 in the vertical direction b along the long hole 5a.
Can be slid. A towing hook 6 is provided at the tip of the towing tube 5.

The support plate 4 has a flange 4 'on its outer periphery.
An elastic material 9 such as rubber is adhered to the automobile body contact surface 4 "of the flange 4 ', or an annular groove-shaped elastic material 9' (FIG. 5) is fitted to the flange 4 '.

Using the tool as described above, the support plates 4, 4 and 4, 4 addressed to a pair of right and left are brought into contact with both sides 12, 12 of the body damage concave portion 11 of the automobile body 8 (FIGS. 2, 7). Suction cups 13 and 2 adsorbed above the center between both sides 12 and 12
The intersections 14, 14 of the vertical legs 2, 2 with the horizontal rod 1 are connected by suspension strings 15, 15 made of nylon sling, and the intersections 14, 14 are suspended (the state is shown in FIG. 1). Shown), the male screw 5 ″ is rotated by the manual handle 7, and a plurality of washer-shaped small rings 16 are erected by spot welding in the recesses 11, and the towed rods 17 inserted through the rows of the small rings 16. Is engaged with the towing hook 6 and the rod 17 is pulled to the outside of the recess 11 (vertical direction b) by the towing tube 5 and the hook 6 so that the recess 11 is continuously wound along the spiral of the male screw 5 ″. It can be restored to the outside in a fine movement state.

The towing tube 5 and the towing hook 6 are connected to the towed rod 1
1, even when the traction force is canceled before and after the engagement with the tool 7, the entire tool is turned sideways by the suction cup 13 and the suspension string 15 while the four support boards 4 are in contact with the both sides 12, 12 as shown in FIG. Can be supported.

In FIG. 1, reference numeral 18 denotes an upper-end locking hook of the suspension string 15, 19 denotes a lower-end locking ring, 20 denotes a support for the towing hook 6, and 21 denotes a screw of the support 20 into the towing cylinder 5. It is a screw.

[0017]

According to the present invention, as described above, the fork fitting can be rotated about the center line of the fork together with the vertical leg and can be tilted freely, and two pairs of support plates are provided at the lower end of the fork fitting. Since the seat is loosely mounted, the fulcrum can be stably set (mounted) in conformity with the inclined surfaces on both sides of the damaged recess of the vehicle body, and the damage recess can be steplessly pulled out along the spiral inclination. There is an effect that the amount of withdrawal can be adjusted to a minute amount, and the restoration operation can be performed quickly and easily.

In addition, there is an effect that the tool can be safely and laterally supported by the suction cup and the suspension string even in a state where there is no danger in the work and the reaction force due to the traction force is not applied to the body from the support plate.
