DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to the drawings, and initially to FIG. 1 in particular, an exemplary glazing panel handling system 20 according to the invention consists of a panel support frame structure 21 comprising four spaced upright poles 1 mounted to a scissors linkage base 11 which enables the support frame 21 to be collapsed from the expanded configuration shown in FIG. 1 to a collapsed configuration shown in FIG. 11 for storage and transportation. The upright support poles may be height adjustable by being telescopic, for example.

At the top of each support post 1 is mounted a plastics or rubber support a pad 2. The upper surface of the support pads 2 is generally planar. Some or all of the pads are provided with a radial surface channel 3 in the top surface. The channel 3 extends completely across the extent of the pad 2. Typically the support pads 2 will be mounted on the support poles 1 in such a way as to allow some movement in order to accommodate curved glass. This may readily be achieved by means of pivotally mounting the pads 2 to the poles.

The frame design may vary but essentially is arranged to be open at opposed sides (i.e. the front and rear) to allow a person to pass through the frame structure 21 completely from one side to the other. An alternative configuration is shown in FIG. 3 in which access is provided completely through the support structure from the front side to the rear by having an open front side 51 and an open rear side 52. The support posts 1 may be cross braced 4 at the sides but the support pads 2 are positioned to have sufficient height clearance from any frame member to allow glass to be placed face downwards without any attached ancillary equipment (suction lifters, lifting and positioning aids etc) being obstructed by the support frame structure.

One or more of the support posts 1 may be adjustable to enable the position of the support pad 2 to be re-orientated. For example, an articulated joint or swivel arrangement 5 may be provided proximate an upper end of the respective support post 1, to allow the pad 2 to be repositioned in order to allow any attached equipment sufficient clearance.

A handling tool 19 is used to enable efficient handling of glazing panels in combination with the panel support structure 20. The handling tool 19 comprises a pivot bar 6 consisting of a rod 7 having mounted suction cups 8 in such a way to allow some movement of the suction cups in order to accommodate curved glass. A tilting or pivoting mounting 13 for the suction cups 8 to the bar may be provided for this purpose. The position of the cups 8 on the bar 7 (and their relative spacing) may beneficially be adjustable. The rod 7 is either circular in cross section or has circular section bearing surface portions arranged, and shaped an dimensioned, to fit into the arc surface groove 3 of the support pads 2 such that the rod 7 can rest and rotate in the groove 3. In a preferred embodiment, the bearing surfaces of the rod and the groove are effectively matched radius circumferential surfaces. It will be appreciated that other surface profiles (such as octagonal, hexagonal, or even square) for the rod 7 will achieve a similar effect, but a circular surface profile is preferred. During use the handling tool 19 is mounted, using the suction cups 8 to a windscreen 9 in such a way that the rod 7 locates into the channel 3 in the top of the pad 2.

In use, the technician 17 stands the windshield 9 on its lower edge located safely into the channels 3 in the upper surface of two of the pads 2. The windshield 9 can then be viewed for the purpose of noticing any defects or scratches prior to fitment. This is the situation shown in FIG. 8A.

The windshield 9 is next laid down to rest supported on the four support pads 2 with the outer face up. This allows for ancillary equipment (suction lifters, lifting and positioning aids etc) to be attached to the outer surface of the glass. The handling tool 19 may also be attached to the outer surface of the windshield 9. This is the situation shown in FIG. 8B.

The windshield may next be turned over, and the Pivot bar 6 of the handling tool 19 is located into the arc-form channels 3 in the upper surfaces of the support pads 2, as shown in FIG. 8C. As the windshield is laid down by rotating the pivot bar 6 in the arc-form channels 3, if the ancillary equipment comes into contact with the pads 2 the swivel arrangement 5 may be moved to allow sufficient clearance. If required the height adjustment of the upright support posts 1 may be adjusted to allow the windshield to lay flat. This can be seen from FIG. 8c in which the pad 2a is at a position higher than pad 2b. In this orientation various operations may be conducted on the windshield 9. For example, cleaning, priming and application of adhesive to the inside face of the glass may now be carried out.

From this position, the windshield can be easily moved to the upright position by lifting the top edge part while the bottom edge part rotates around, and is supported by, the pivot bar 6 resting in the channels 3. this situation is shown in FIG. 8D, where it can be seen that the technician 17 can walk via the open end of the structure across the perimeter of the structure and into the space between the support posts 1 at the perimeter of the structure.

The glass is now fully supported and the technician can adjust his grip, holding either pivot bar 6 of the handling tool 9 and/or additional suction lifters and/or ancillary positioning equipment. This situation is shown in FIG. 8E. The windshield can next be lifted from the support frame structure in a safe manner with a straight back. If required the height adjustment of the upright poles 1 can be adjusted to suit the stature of the individual technician in order that lifting is done in the safest manner.

As shown in FIG. 8E, the technician can continue walking through the perimeter of the support structure via the opposite open end of the frame, holding the windshield 9 in a safe manner with a straight back, and take the windshield to the vehicle to finish the installation.

An alternative configuration is shown in FIGS. 9 and 10 in which access is provided completely through the support structure from the front side to the rear by having an open front side 151 and an open rear side 152. The arrangement is generally similar to the embodiment of FIG. 3. The support posts 101 may be cross braced by upper and lower cross braces 104a, 104b at the sides and a rear ground bar 131 is provided connecting across the rear posts 101b. The cross braces are hinge mounted to the rear support posts 101 at hinge mountings 134, enabling the structure to be collapsed for transportation and storage.

The forward support posts are effectively divided in two having upper support posts 101a offset spaced transversely to the axial direction, from lower support posts 101b. This enables the support pads for engaging the glazing panel to be optimum spaced, whilst the ground engaging support posts are optimum spaced for stability. For this reason also, the ground engaging support posts 101b and 101 are inclined slightly toward one another from a more widely spaced base to a narrower upper portion.

As with the earlier described embodiments, the embodiment of FIGS. 9 and 10 is arranged to be open at opposed sides (i.e. the front and rear) to allow a person to pass through the frame structure 121 completely from one side to the other.

The support pads of the earlier embodiments are provided at the corners but in this embodiment the two forward pads 102a are plastics or rubber and provided with a channel 3 for receiving the edge of the glazing panel, whereas the two rear pads 102b are customised friction mounts, which may be made low friction by having a central low friction material central proud standing button 102c or rotatable ball. Alternatively the custom friction mounts may be made high friction mounts for example by having a central rubber or other high friction material central proud standing button 102c. In certain embodiments high and low friction custom mounts may be provided alternatively on each of the custom mounts 102b.

Just below the rear mounts 102b are provided docking brackets 137 for receiving the opposed ends of the handling tool 19.
