Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for repairing an automobile outer panel for repairing a recess formed in an outer panel of an automobile, and a repair tool particularly suitable for use in the method.

[0002]

2. Description of the Related Art When a recess is formed in the outer panel of an automobile due to a collision accident or the like, a drawer hole is opened in the recess by a drill,
Conventionally, a repairing method has been used in which the leading end of the pulling rod is passed through the pulling hole and then the pulling rod is pulled to pull out the recess. Also, without opening the pull-out hole, the pull-out end of the pull-out rod is fixed to the concave surface,
After that, a method of pulling out the recess by pulling the pull-out rod is also used.

After the recess is pulled out, putty is applied to the repaired portion to form a smooth surface, and then repainting is performed to complete the repair.

[0004]

By the way, such a repairing method is effective when the recess formed in the outer plate of the automobile is large, but this repairing method is used when the recess is small or inconspicuous. Is not very suitable. This is because it takes too much time and money as a repair method for the concave portion that can be left unrepaired, and it is compared with the unrepaired state due to the subtle color difference generated at the repainted part. It is not possible to obtain a high repair effect. Therefore, a method of hammering out from the back side with a hammer may be used for small recesses.This method allows repairs to be completed at a low cost in a short time, and there is no need to repaint, so the outer panel can be colored. Although there is no difference, it is difficult to tap and the skill is required to obtain a satisfactory repair result.

Accordingly, the present invention provides a method for repairing an automobile outer panel, which can repair a small recess in a short time, at low cost, and easily, and a vehicle outer panel repairing tool suitable for use in this method. To aim.

[0006]

In order to achieve this object, a method of repairing a vehicle outer panel of the present invention is a vehicle outer panel repairing method for repairing a recess formed in an outer panel of an automobile. A stick-shaped repair tool is inserted between the repair tool and the inner member located inside the outer plate, the repair tool is pressed against the inner member, and the tip portion of the repair tool presses the recess. A rotating force is applied to the tool, and the concave portion is pushed outward by pressing by the tip portion. It is usual to provide a handle at the rear end of the stick-shaped repair tool so as to easily apply a rotational force.

There is a case in which the tip of the repair tool is bent and a rotational force acting on the intermediate portion as a rotary shaft is applied to press the tip into the recess.

[0008]

By applying a rotational force about the contact side with the inner member to the repair tool, the tip portion tries to rotate so as to press the back side of the recess toward the outside. As a result, the concave portion is pushed outward. If no suitable inner member is provided, a special inner member may be fixed for repair.

As one of the modes of applying a rotational force to the repair tool, the repair tool functions as a leverage by using the contact point with the inner member as a fulcrum, and as a result, the tip portion presses the recess.
There is a case where a rotational force is applied. Further, as another aspect, the tip end portion of the repair tool is bent, and the intermediate portion pressed against the inner member serves as a rotation axis, and as a result, the tip end portion presses the recessed portion, so that the rotational force acts. There is a case to let. When a handle is provided at the rear end of the repair tool (stick body), the handle is gripped to exert a rotational force. It is preferable that the tip portion of the repair tool (stick body) is formed in a size or shape capable of partially pressing a small concave portion, and one portion is extruded.
It is effective to finally push out the entire concave portion while shifting the pressed portion such that another portion is then pushed out.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of an automobile skin repair tool according to the present invention.

The vehicle outer plate repair tool 1 is constructed by deforming a stick body having a diameter of about 8 mm, and a handle 3 is folded back at the rear end. The tip portion 5 of the vehicle outer plate repair tool 1 is bent at a right angle to the extending direction of the handlebar 3 and at an obtuse angle with the middle portion 7,
As shown in detail in FIGS. 2 and 3, flat surfaces 9 and 9 are formed on both left and right sides of the tip portion 5 (FIG. 2 shows the tip portion 5).
Of FIG. 3, and FIG. 3 is a cross-sectional view taken along line XX of FIG. The planes 9 and 9 are formed so that the width gradually increases toward the tip, and therefore the thickness of the tip portion 5 gradually decreases toward the tip. The diameter of the car skin repair tool is 4 mm
It is preferably 12 mm or less.

FIG. 4 is a cross-sectional view for explaining a case of repairing a car door (the roof may be repaired) using the car skin repair tool 1.

When the automobile door is repaired, the inner panel 11 (inner member) is once removed, the door glass (not shown) and the like are removed, and then the inner panel 11 is attached again. Then, the automobile outer plate repair tool 1 is inserted from the tip portion 5 between the inner panel 11 and the outer panel 13 (outer plate). A small recess 15 is formed in the outer panel 13, and the tip portion 17 of the automobile outer plate repair tool 1 is located at a height capable of pressing the recess 15.
After that, when the automobile skin repair tool 1 is rotated a little,
, The lower end of the intermediate portion 7 is pressed against the back side of the inner panel 11, and the tip portion 17 is recessed on the flat surface 9 side.
The back side is pressed (FIG. 5 is a plan view for explaining the case of repairing an automobile door). In this state, the handle 3 (see FIG. 1) is gripped to apply a rotational force in the direction of the arrow such that the intermediate portion 7 is used as a rotation axis, and the tip portion 17 is pressed to push the concave portion 15 outward. In repairing, it is effective to first push out from the outer peripheral portion of the recess 15 and then gradually move the pushed portion toward the center. If the recesses 15 are pushed out irregularly, fine waviness may occur after the repair is completed.

Reference numeral 19 in the drawing denotes a reinforcing member for the outer panel 13. In addition, as shown in FIG.
1 may be enlarged to form the handle 23, and a hand may be inserted between the folded-back spaces 21 so that only the rear end bar 25 of the handle 23 can be gripped. When only the rear end bar 25 is gripped, the amount of protrusion of the back of the hand in the direction perpendicular to the extending direction of the handle 23 can be reduced as compared with the case where the entire handle 23 is gripped, so that work can be performed even when the outer space of the handle 23 is narrow. It is possible to proceed smoothly.

A front side portion 33 extending in a direction perpendicular to the intermediate portion 7 and a rear side portion 37 which is bent in a direction away from the mounting portion 29 and has a grip 35 at a rear end.
A fitting portion 41 is provided at the tip of the handle 39 formed by the, and a plurality of vertical grooves are provided at equal intervals in the circumferential direction so that the fitting portion 41 engages with the mounting portion 29 in the circumferential direction. A mounting hole 45 in which 43 is formed is provided.
Therefore, the handle 39 can be attached to the tip portion 47 at an appropriate angle. Tip 47
Has a circular cross-sectional shape, but the tip portion 49 is configured to gradually reduce its diameter toward the tip.

FIG. 8 is a view showing another modification of the vehicle outer plate repair tool according to the present invention.

The vehicle outer plate repairing tool 51 is formed by making the middle part of the vehicle outer plate repairing tool 1 shown in FIG. 1 short and not bending the tip. That is, the middle portion and the tip portion extend straight. Flat surfaces 55, 55 are formed on both upper and lower sides of the tip portion 53, and the flat surfaces 55, 55 are formed so as to gradually widen toward the tip. Therefore, the thickness of the tip portion 53 in the vertical direction gradually decreases toward the tip.

FIG. 9 is a cross-sectional view for explaining a case of repairing a car door by using the car skin repair tool 51 (in some cases, repairing a roof or the like).

An automobile outer plate repair tool 51 is inserted from the tip portion 53 between the inner panel 11 (inner member) and the outer panel 13 (outer plate). A small recess 57 is formed on the outer panel 13 at the upper side, and the outer panel repair tool 51
The intermediate portion 59 is pressed against the upper end of the inner panel 11, and the tip portion 61 is in a state in which the recess 57 can be pressed by the flat surface 55 side. Handle 3 in this state
