Embodiment Construction

[0040]FIG. 1 shows the prior art metal panel repair tool U.S. Pat. No. 2,749,795, dated Jun. 12, 1956 issued to Boykin, Jr. This device provides a support post 20 with a base 18 shaped to rest against an adjacent portion of an outer body panel 10 overlying an inner body panel 8 on a vehicle. To this post 20 is connected a hinged lever arm 24 with an extending handle portion which, in turn, carries a connecting or pulling rod 36 for coupling to the dented portion 12 of the surface 10 which is to be drawn-out. This mechanism acts as a second lever.

[0041] The pulling rod 36 is fastened to a sheet metal screw 45 which engages with the inwardly-dented sheet metal surface 10. The lever arm 24 and support post 20 are depicted as being at 90° to each other at the commencement of the pulling process. In this configuration the pulling rod 36 is parallel to the upright support post 20 which extends vertically from the auto body surface 10. No provision is made for the pulling rod 36 to swivel...

Abstract

A tool for pulling a dent out of a sheet metal surface has a support post with a foot shaped to rest against a portion of the sheet metal surface adjacent the dent. The tool includes a hinged lever arm which is pivotally connected to this support post at a lever arm pivot point which is elevated above the foot and adjacent sheet metal region. The tool also includes a pulling rod for coupling, through a fastener or connecting means, to the dented portion of the surface which is to be drawn-out, the pulling rod being connected to the hinged lever arm through a pivoting joint. The pivoting joint of the pulling rod and the lever arm pivoting point are positionable through actuation of the lever arm able to lie in a common plane which is substantially parallel to the sheet metal surface into which the dent is to be drawn into alignment. The pulling rod is adjustable in its engagement with the lever arm to permit the lever arm to swing through a limited angular range. Coupling between the pulling rod and lever arm is either discrete or continuous. Fasting means connecting the tool to the sheet metal include a self-tapping, self-drilling screw or a bolt provided with a magnetic washer or magnetic head.

Description

FIELD OF THE INVENTION [0001] This invention relates to a tool for pulling dents, amongst other applications, from the sheet metal portions of an auto body in the process of auto-body repairing and refinishing. More particularly, the invention relates to a hand-operated pulling device with an improved system for connecting to and applying force to the surface which is to be pulled. BACKGROUND TO THE INVENTION [0002] Various devices have been proposed to allow an auto-body repairman to apply an outward force to an inwardly dented surface, restoring the surface to close to its original profile. One example is U.S. Pat. No. 2,749,795, dated Jun. 12, 1956 issued to Boykin, Jr. (FIG. 1 hereafter). This device provides a support post with a foot shaped to rest against an adjacent portion of a body panel on a vehicle. To this post is connected, at a height above the panel, a hinged lever arm with a handle which, in turn, carries a connecting rod for coupling to the dented portion of the su...
