Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a vehicle body repair tool used for extending a vehicle body deformed by an impact such as a collision accident to restore it to its original state.

[Conventional technology]

As a recent tendency, automobiles, such as passenger cars, have been made as lightweight as possible in order to save fuel consumption, etc. Therefore, the vicinity of the foot of the front seat is weakened due to the body structure.

Therefore, when an accident such as a frontal collision occurs,
The area near the feet of the front seat, which is a little deeper than the front part of the vehicle body, is easily compressed and deforms.

[Issues to be solved by the device]

In the case of repairing the vehicle body, the vehicle body is fixed and the front end of the vehicle body is clamped with a clamp at the tip of a tension chain extending from a known tower type repair machine at an appropriate place, and a pulling operation is performed, Due to the nature of the metal, the area around the feet of the front seat rarely returns to the original state, and the repair work was difficult.

In view of this, the vehicle body modification tool of the present invention utilizes a pair of parallel ribs projecting transversely on the back surface of the front seat so that the deformation of the lower surface of the front seat can be completely restored.

[Means for Solving the Problems] A vehicle body modification tool of the present invention is a screw shaft having a predetermined length and thickness, a receiving nut screwed to one end of the screw shaft, and a screw shaft inserted through the screw shaft. At least one washer, two intermediate nuts to be screwed into the screw shaft, a screw hole into which the screw shaft is screwed at one end, and a through hole for locking a hook is provided at the other end. And a hook locking member.

[Action]

In the vehicle body corrector configured as described above, first, the screw shaft is inserted into the reference holes on the same axis formed in the pair of ribs projecting transversely on the rear surface of the foot of the front seat of the vehicle body, and the screw shaft is inserted. The two intermediate nuts are screwed together and the two intermediate nuts are arranged between the pair of ribs. Then, a washer is fitted into the rear end portion of the screw shaft projecting from the rear rib, and the receiving nut is screwed.

Next, tighten the rear intermediate nut so that the rear nut is sandwiched between the intermediate nut and the receiving nut via the washer, and the front intermediate nut is screwed in the opposite direction to contact the rear surface of the front rib. The screw shaft is fixed by making contact. Further, a hook locking member is mounted by screwing a screw hole of a screw cylinder to the tip end of the screw shaft, and a hook at the tip of the tension chain extending from the tower-type repair machine is engaged in the through hole of the hook locking member. Stop it. In this state, the tension chain is pulled to restore the deformation of the vehicle body.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. In the figure, 1 is a screw shaft having a predetermined length and thickness, and 2 is a receiving nut which is screwed together with a washer 3 at its rear end.
The screw shaft 1 is longer than the distance between a pair of ribs 11 and 11 ', which will be described later, and slightly smaller than the diameter of the reference holes 12 and 12' formed in the ribs 11 and 11 '. Reference numerals 4,5 designate a pair of intermediate nuts screwed onto the screw shaft 1. Reference numeral 6 is a hook locking member having a screw cylinder 8 integrally projecting at its rear end, which has a through hole 9 formed at its front end, and a screw hole into which the tip of the screw shaft 1 is screwed into the screw cylinder 8. 7 is drilled.

In FIG. 2, reference numeral 10 designates a rear surface of the feet of the front seat of the vehicle body A, a so-called lower arm, in which the vehicle body A is located.
A pair of parallel ribs 11 and 11 'are projected downward at regular intervals along the width direction of the
12,12 'are opened along the same central axis. The reference holes 12 and 12 'are usually used as reference points when measuring the reference dimensions.

Next, a method of using the vehicle body modification tool of the present invention having the above structure will be described. First, the screw shaft 1 is attached to the pair of ribs 11,1.
The two intermediate nuts 4,5 are screwed into the screw shaft 1 while being inserted into the reference holes 12, 12 'formed in 1'.
Are arranged between the pair of ribs 11 and 11 '. Then, the washer 3 is fitted into the rear end portion of the screw shaft 1 protruding from the rear rib 11 ', and the catch nut 2 is screwed. In this state, the rear intermediate nut 5 is tightened, and the rear rib 11 'is sandwiched and fixed between the intermediate nut 5 and the receiving nut 2 via the washer 3. The intermediate nut 4 on the front side is screwed in the opposite direction to abut on the rear surface of the rib 11 on the front side. As a result, the screw shaft 1 is tightly fixed to the ribs 11 and 11 '. Finally, the hook hole 7 of the screw cylinder 8 is screwed into the tip of the screw shaft 1 to attach the hook locking member 6.

Then, a tower type correction machine (not shown) is arranged and fixed in front of the front side of the vehicle body A, and a hook (not shown) at the tip of a tension chain (not shown) extending from the tower type correction machine is attached to the hook engagement device. The deformation of the lower arm portion is restored by locking the stopper member 6 in the through hole 9 and pulling the stopper member 6.

At this time, of the pair of ribs 11, 11 ', the rear rib 11'
Is fixed by sandwiching it with the intermediate nut 5, the washer 3 and the receiving nut 2, and the rib 11 on the front side abuts the intermediate nut 4 on the rear side so that both ribs 11 and 11 'and the vehicle body corrector are integrated. Since it is pulled out, the deformation of the lower arm can be restored without deforming only the ribs 11 and 11 '.

A washer 3 may be further interposed between the intermediate nuts 4 and 5 and the inner surfaces of the ribs 11 and 11 '. In this case, the intermediate nuts 4 and 5 can be used even if they are small.

[Effect of device]

As described above, the vehicle body modification tool of the present invention can be mounted easily and surely by utilizing the reference holes provided in the two ribs protruding from the lower arm, and the traction force can be directly applied. Can be effectively applied to completely repair the deformation.

Moreover, it has the advantage that the structure is simple, it is easy to operate, and it is economically excellent.
