Description

[0001] DENT RESOURCE DEVICE [0002]

The present invention relates to a dent restoration apparatus, and more particularly, to a dent restoration apparatus that is simple in structure and simple in use, and capable of restoring a dent to a maximum extent.

Generally, a dent is a collision caused by a slight impact on the vehicle body (for example, a hail, a stone, a baseball, a shock due to a door of a side vehicle in a parking lot) or a light contact with a bicycle, a motorcycle, Which means that it is concave and elastically deformed to cause scratches. Such a dent is a factor that significantly lowers the value of a vehicle when it occurs in a high-end passenger car or a new car body that emphasizes the appearance of the vehicle body. When repairing such a tent through a process such as sheet metal painting or painting, an excessive cost is incurred, and environmental pollution due to the painting operation occurs, thereby increasing the social cost thereof. Therefore, in order to restore most of the dent, the position of the dent is detected, and then a tool is used to strike or push the rear surface of the dent.

However, in the conventional dent restoration method, it is difficult to insert various kinds of tools into the rear surface of the dent in the gap of the vehicle body, and when the gap of the vehicle body is insufficient, the vehicle body must be disassembled. It may be necessary or secondary body damage may occur. In addition, there is a problem in that slight damage or breakage often occurs due to the control of the force when pushing or hitting, and it has to rely on the sense of a skilled professional for a long time.

The guide means 50 includes a guide hole 51 formed in a slit shape in the pivotal lever and a guide pin 52 provided in the elevating bar 30 and fitted in the guide hole 51. The guide pin 52 may protrude from the outer circumferential surface of the elevating bar 30 and may be a pin inserted through the elevating bar 30. In this embodiment, the guide pin 52 is in the form of a pin which is inserted into the elevating bar 30 so as to penetrate through the elevating bar 30, for example.

The elastic member is a compression coil spring 70 which is provided between the reference lever 10 and the suction member hanger part 40 and is compressed when the lifting bar 30 is lifted or lowered. The elastic member is a compression coil spring 70. However, the present invention is not limited thereto. If the elastic member is compressed when the lifting rod 30 is lifted and restored when the lifting rod 30 is lowered, Anything is possible.

A spring support 72 for supporting the compression coil spring 70 is provided at a lower portion of the reference lever 10. The spring support 72 is hollow, and the lifting rod passes through the spring support 72, and the compression coil spring 70 is fitted to the outer side. The spring support 72 prevents the compression coil spring 70 from shaking when the compression coil spring 70 is tensioned or compressed.

Referring to FIG. 7, the pedestal 60 supports the reference lever 10, the pivotal lever 20, and the elevating bar 30. The pedestal 60 is formed so that the elevating bar 30 can be detachably mounted in the horizontal direction and supports the lower portion of the elevating bar 30 on the vehicle body. The pedestal 60 is composed of a lift-up bar coupling plate 61, left and right swing plates 62, and left and right swing plates 63. The elevating rod coupling plate 61 is formed with an elevating rod receiving groove 61a having one side opened so that the elevating rod 30 is inserted. The left and right swash plates 62 are extended at an angle to the left and right sides of the elevating rod coupling plate 61 at an angle. An opening 62a is formed in at least one of the left and right swash plates 62. The left and right swing plates 63 are coupled to the left and right swash plates 62 by hinge shafts 64 so as to be brought into close contact with the vehicle body 2.

The operation of the dent restoration apparatus according to the embodiment of the present invention will now be described.

2, the adsorption member 80 is adsorbed to the dent 4 generated in the vehicle body 2 and the head 82 of the adsorption member 80 is adsorbed to the adsorption member receiving grooves 41 ). When the adsorption member (80) is adsorbed to the dent (4), an adhesive or the like is applied to the dent (4) to increase the adhesive force.

The pedestal 60 is fitted to the elevating rod 30 so that the pivotal plate 63 of the pedestal 60 is brought into close contact with the vehicle body 2. The height of the pedestal 60 can be appropriately adjusted while the pivot plate 63 is rotatable about the hinge axis 64. [ In addition, the pedestal 60 can be rotated in the horizontal direction on the vehicle body 2 while being sandwiched by the elevating bar 30. Therefore, it is possible to change the position of the pedestal 60 in accordance with the position or the field of view of the operator, so that the convenience of the work can be improved. That is, it is possible to change the position of the pedestal 60 so that the pedestal 60 does not block the view of the operator.
