DESCRIPTION:
BRIEF SUMMARY
This invention relates to sheet material handling frames. The invention is particularly applicable to a frame for handling quantities of materials such as glass in sheet form both for storage and for transport.
In the glass industry large area sheets of glass are manufactured called "jumbo" sheets. These jumbo sheets are supplied by the manufacturer to a distributor for cutting into apparatus smaller standard sizes. The jumbo sheets are usually cut according to demand for different sizes. Clearly, when a jumbo sheet is cut consideration has to be given to the optimum way in which it can be done to minimise the amount of wasted material. Thus, a specific order for glass may not be satisfied from a single jumbo sheet in which case it is necessary to store sheets of glass not only prior to distribution but also while an order is awaiting completion.
Consequently, a warehousing facility for prepared glass requires that the glass can be stored and transported about a site with as much ease as possible. Furthermore, it is necessary that the glass can be loaded for distribution as conveniently as possible.
A frame for transporting and storing sheet glass is known in which a generally L-section frame provides a foot for a base on which one edge of a stack of sheets of glass rests and a supporting upright stanchion against which the stack is leant. The stack is held in place against the upright stanchion of the L-section frame by a vertical bar which has a peg formed on its lower end which engages with one of a series of slots in the foot according to the thickness of the stack. The upper end of the vertical bar is secured to an upper horizontal bar, extending from the stanchion, by means of a bolt which protrudes through one of a series of through holes in the upper bar, again according to the thickness of the stack. The glass is held together by means of a horizontal strap which passes around the stack. A lifting bar is attached to the top of the upright by which the glass can be lifted.
A T-section frame has also been proposed. However, only one size of sheet of glass can be stacked against the sides of a central supporting upright. The sheets are strapped to base boards, provided on the lower arms of the T-section frame. Wooden blocks are placed on the top of the stack in the way of the straps to clamp the glass in place. The straps are thus used to bind the stack together and secure it to the frame. Outermost central uprights are provided with lifting points to which a hoist can be attached in order to transport the loaded frame.
Furthermore the T-frame assemblies are made up from several components comprising steel members, timber platforms and cardboard strips. The timber items themselves have to be assembled from planks which have to be cut to size and trimmed prior to being assembled. Thus, the time and labour required to build enough T-frames can be considerable. While the steel members are often collected from customers the timber is often damaged and, in any event, rarely returned.
Another significant disadvantage of these known T-section frames is that the frames must be secured in place when being transported by, for example, road. The more or less custom-built T-section frame does not have a standard base which could be secured to any standard securing means on the vehicle.
It is an object of the present invention to provide a versatile frame for supporting sheet material which can be easily loaded and which is both secure and stable.
According to the present invention a sheet material handling frame comprising a base for supporting the material, at least one stanchion extending up from the base, first securing means for retaining the bottom of the material against at least one stanchion, and lifting means attached toward the top of the stanchion by which the apparatus may be transported, is characterised in that the second securing means are longitudinally movably retained by the stanchion to accommodate different heights of sheet.
Preferably, the apparatus is provided with a lifting bar which is re
