ABSTRACT:
FIELD OF THE INVENTION
This invention relates to apparatus and assemblies for storing, transferring, and transporting automobile windshield and window covering panes of glass.
BACKGROUND OF THE INVENTION
Rollably extendable and retractable glass pane racks having a multiplicity of vertically extending glass pane supporting shafts are known. Typically, such glass pane racks are rollably mountable within a rectangular support frame; such support frames typically providing paired roller tracks for receipt of laterally extending wheels or rollers. Commonly, such rectangular frames are fixedly mounted upon the bed of a truck. Such frames may alternately be fixedly mounted upon other above ground level surfaces such as a warehouse storage rack or shelf. Where such rectangular support frames are, for example, installed upon the bed of a truck, rollable motion of the glass rack for cantilevered extension beyond an edge of the truck bed allows a worker to conveniently access the glass rack for loading or off-loading of glass panes.
The instant inventive assembly allows a rollably mounted glass rack such as described above to be safely and conveniently alternately utilized as a glass pane transport pallet. Such additional function is achieved by providing roll stopping means integral with the rectangular support frame; the roll stopping means being adapted to function as a releasable safety operatively engagable with a glass rack transporting cart.
BRIEF SUMMARY OF THE INVENTION
The present inventive glass pane storing and transporting assembly preferably comprises a rectangular base frame adapted for fixed installation upon the bed of a truck. Alternately, the rectangular base frame may be installed upon a warehouse storage rack or storage shelf. Preferably, the base frame comprises a pair of longitudinally extending side beams and a crossbeam, the crossbeam spanning between and rigidly interconnecting the forward ends of the side beams. Preferably, the side beams in combination with the forwardly mounted crossbeam form and define a rearwardly opening glass rack receiving space. Also preferably, the inwardly facing surfaces of the side beams form “C” channel roller tracks within which wheels extending laterally from a base frame of a glass rack are rollably mounted. Such rollable mounting preferably allows such glass rack to alternately move forwardly and rearwardly within the glass rack receiving space. Suitably, the wheels may be rollably mounted upon the inwardly facing surfaces of the side beams, such wheels providing rolling support of roller track surfaces extending longitudinally along the left and right sides of the glass rack.
The open rearward end of the glass rack receiving space allows a glass rack rollably mounted therein to move rearwardly from such space, to disengage from the rectangular base frame, and to separately function as a glass pane transporting pallet. Preferably, an elevationally adjustable or height adjustable rollable cart adapted for carrying the glass rack is utilized, such cart being adapted to facilitate direct transfers of the glass rack from the rectangular base frame.
In order to prevent the glass rack from rollably moving out of the glass rack receiving space of the base frame in the absence of a properly positioned glass rack carrying cart, a roll stop is provided, the roll stop preferably being adapted to allow rearward passage of the glass rack upon rearward positioning and matching elevational adjustment of the glass rack carrying cart.
Accordingly, it is an object of the present invention to provide an assembly having a glass pane carrying rack capable of functioning as an alternately extendable and retractable shelf for convenient loading and off-loading of glass panes safely; and capable of alternately functioning as a separable cart transported glass pane handling pallet.
Other and further objects, benefits, and advantages of the present invention will become known to those skilled in the art upon review of the Detailed Description which follows, and upon review of the appended drawings.
