ABSTRACT:
This invention relates to a jig
In GB-A-2 223 460 there is disclosed a jig comprising a carrier and an elongate member an end portion of which is located relative to the carrier so that the elongate member is moveable arcuately upwardly and downwardly on a first axis and is rotatable on a second axis extending at right angles to the first axis.
In U.S. Pat. No. 5,549,287 there is disclosed a jig comprising a carrier and an elongate member an end portion of which is located relative to the carrier so that the elongate member is moveable upwardly and downwardly and is rotatable on an axis extending at right angles to the upward and downward movement.
The jigs disclosed in the two documents are intended for supporting motor vehicle panels and other bodywork members to be worked on and provide adjustment whereby the panels and other bodywork members may be supported in a variety of positions while worked on.
While the jigs disclosed in the two documents may be suitable for supporting motor vehicle panels and other bodywork members in a variety of positions, they do not include means for facilitating movement of such panels and other bodywork members towards and away from the elongate member. Therefore, such jigs do not provide a device capable of manoeuvering such panels and other bodywork members through any degree of are in any radius.
In U.S. Pat. No. 5,203,540 there is disclosed a jig comprising a carrier and an elongate member an end portion of which is located relative to the carrier so that the elongate member is moveable arcuately upwardly and downwardly on a first axis. However, the elongate member is not rotatable on a second axis extending at right angles to the first axis. The elongate member is a parallel crank four-bar linkage arranged to prevent angular deviation of a connecting bar supporting a mounting means, the connecting bar being a component of the elongate member.
According to the invention, there is provided a jig comprising a carrier and an elongate member an end portion of which is located relative to the carrier so that the elongate member is moveable arcuately upwardly and downwardly on a first axis and is rotatable on a second axis extending at right angles to the first axis characterised in that there is provided article engaging means located at an end portion of the elongate member remote from the first and second axes and moveable towards and away from the elongate member on a third axis extending transversely of the elongate member.
Following is a description, by way of example only and with reference to the accompanying drawings, of one method of carrying the invention into effect.
