FIG. 2 is an end view of the (upper) container of FIG. 1;
FIG. 3 is a detail view of a part of the (upper) container of the preceding figures.



DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to the drawings, there is shown in FIG. 1 a container 1 for use in transporting vehicle windscreens. The container will be described primarily in this context, although it should be readily appreciated that the invention extends to containers for transporting other fragile items, particularly other fragile sheet items.
The container 1 is of welded tubular frame construction and demountably mounted atop a similarly constructed lower container 2. Both upper and lower containers 1,2 include openings 3 in their respective frames to accommodate tines of lift/transport apparatus such as fork lift apparatus.
The upper container 1 is provided in accordance with the invention. The container 1 includes an open top and a closed end wall 4. The end opposite the closed end may be open. The sides of the container 1 include side panels 5,6,7,8 one or more of which may comprise movable doors, the purpose of which will be described in detail hereafter. For example in the embodiment shown in the drawings, doors 5 and 7 pivot on respective support posts to effectively open respective corners of the container, thereby to enhance access to the ends of the container for loading or unloading of the container. Door 5, for example is mounted by means of pivot mountings 66,67 to support post 68.
Spanning the width at the base of container 1 are three slide bars 9,10, 61 each having low friction hard upper surfaces. A further slide bar 62 is fixed at the bottom of the container adjacent openable door panel 5. The purpose of the slide bars 9, 10, 61 and 62 is to engage and support the lower edge of the windscreen during loading and unloading of the container. The glass is moved to slide over the upper surface of the bars. The upper surface of the bars may comprise a low friction material such as PTFE.
A central securing column 11 is mounted on support rollers 12 which are constrained to roll along rails 52, 53 spanning the opposed sides of the container 1. Inwardly of and alongside rails 52, 53 extend respective securing bars 14,15 including a series of spaced securing holes 16 along their length. The column 11 carries a plate 55 having at its foot respective securing bolts (not shown) which are spring biassed to engage through plate 55 within the holes 16. In this way column 11 can be moved in the width direction of the container and secured in position at the desired location. This facilitates loading and unloading the container and also makes the container adaptable to carry differing quantities of windscreens or windscreens of differing size and curvature configuration.
The movable column 11 provides a coarse adjustment for securing the windscreens in position. The arrangement additionally includes a fine adjustment system for final securing of the windscreens in the container. In the embodiment shown the arrangement includes upper and lower pairs of paddles 17, 18 mounted tiltably to the column 11. The paddles 17, 18 are provided with conformable face layers (for example of polyurethane foam pads) to engage the adjacent windscreen, and may be mounted to the column 11 by means of respective ball mountings giving the paddles the facility to tilt in 2 planes. This provides a great deal of flexibility for securing, however paddles tilting about a single pivot axis have been found to work satisfactorily in most situations. Such an arrangement is shown in the drawings in which the paddle pairs 17,18 are mounted to a tilt mount 57 to tilt in the vertical plane as shown by arrows B in FIG. 2. The paddles are movable into and out of approachment with the windscreens present in the container by means of actuating in rotary fashion handles 19 to rotate a threaded shaft 20 threadably mated in a threaded bore in the column 11. This causes paddle pairs 17,18 and respective tilt mounts 57 to advance or retreat across the width of the container as shown by arrows A in FIG. 2.
It is greatly preferred that the fine securing adjustment system includes means for limiting the securing force applied by the paddles. This can be achieved in a number of ways, for example by using mechanical means such as torque limiting clutch arrangements or by use of load or pressure sensors to indicate when maximum permissible force has been applied. This results in less likelihood of inexperienced or careless operators overstressing and potentially damaging the windscreens in the container, or conversely failing to secure the windscreens adequately in the container.
The side of the container opposite the column 11 is provided with complementary pairs of paddles 21, 22 tiltably mounted to a post 23 at the side of the container. The paddles may be height adjustable on the column 11 or post 23. In the arrangement shown the paddles 21, 22 are height adjustable on brackets 24 mounted to post 23.
The container additionally includes a brake system intended to restrict longitudinal movement of windscreens present in the container. The brake system is re-configurable between a brake engaged condition and a brake released condition. The brake arrangement comprises a pair of brake bars 25,26 running alongside the slide bars 9, 10 so as to be positioned below the edge of the windscreens present. In the brake release configuration, the upper surfaces of the brake bars 25,26 are positioned below the level of the upper surface of the slide bars 9,10. This permits the lower edges of the windscreens to slide over the upper surface of the slide bars 9,10 without hindrance from the brake bars 25,26. In the brake engaged configuration, the brake bars are raised such that the upper surfaces of the brake bars engage the lower edges of the windscreens present. In the brake engaged position, the upper surface of the brake bars 25, 26 will typically be positioned just above the upper surface level of the slide bars 9,10.
In the embodiment shown, reconfiguration of the brake system between the engaged and released configurations is achieved by means of respective lever and cam arrangements for the brake bars 25,26. Levers 28,29 are operated to rotate a shaft below the bars 25,26, the shaft including offset cams which raise or lower the bars 25,26 dependent upon the rotary position of the shaft.
The upper surface of the brake bars is beneficially of friction enhancement or grip enhancement material. A conformable pad layer of rubber or other such like grip material may be provided for this purpose.
The container unit is provided with upper and lower corner mounting bosses 30 to 37 permitting like container units to be stacked one on top of the other, or alternative container units to be stacked. In a preferred embodiment of the invention the windscreen container unit may be stacked on top of a container unit used for storing other fitting materials. This arrangement is shown in FIG. 1, in which the windscreen storage unit 1 is mounted on top of a container unit 2 for storing other handling or fitting items. The lower container unit 2 includes slide doors 40, 41 for accessing the interior of the container 2.
In use the container can be conveniently loaded in a warehouse or other environment. The lower fork lift tine receptor openings 3, make the container particularly suitable for this purpose. The slide bars enable the windscreens to be readily positioned longitudinally. The openable end side doors provide enhanced operator access. The movable column can be retracted from the opposed wall in stages as the container is loaded. The paddles are then urged into securing engagement without overstressing the windscreens. This secures the windscreens from movement in the width direction of the container. The brake system can then be activated to engage the brake bars with the underside of the windscreens. This secures the package of screens against longitudinal movement. Containers may then be stacked for optimum space conservation during transport. Typically soft packaging material will be positioned intermediately between adjacent windscreens. At the unloading location, the brake system can be disengaged and the paddles released. The open top, end, and openable end side door permits any individual screen from the batch to be readily retrieved by operators.
The container is particularly suitable for use for transportation and/or storage of a batch of different size and or shape (for example curvature) windscreens, due to the flexibility of re-configuration of the container, the securing against both longitudinal and transverse movement of the windscreens and the facility to guard against over or under tightening of the transverse securing mechanism.
