Additionally, an alternate way to support some of the wheels 50 together with some of the axle spindles 40 are to employ shorter angle supports 52 which possess an axle spindle aperture for matingly receiving axle spindles and mounting apertures for fixed attachment to the underside of the moveable tray 30.
Referring to FIG. 3 and 4, it can be shown that the retaining latch 60 is comprised of a handle 61, a pull cable 62, a redirection pulley 63, a retainer pin 64, a mounting bracket 65, and a spring return means 66 where the handle 61 is fastened to one end of the pull cable 62 and the other end of the pull cable 62 is fastened to the retainer pin 64 and where the pull cable 62 is redirected by the redirection pulley 63 which is rotationally fastened to the moveable tray 30 and the retainer pin 84 is matingly, operably, and slideably received within retainer pin apertures which are formed into the mounting bracket 65 which is further defined as a u-shaped bracket having an upper flange and a tower flange joined together by a back wall and where the back wall is fixedly attached to the moveable tray 30 and the upper flange and the lower flange each include the retainer pin aperture and where the retainer pin apertures are axially concentric with each other and where the retainer pin 64 also protrudes through the spring return means 66 which is biasedly applied to cause the retainer pin 64 to normally extend protrudingly downward into mating cargo compartment apertures therefore retaining the moveable tray from traversing movement.
In use, a passenger bus is equipped with the present invention is and the user can more easily load cargo into the bus, saving back pain and other exasperating energies.
In an alternate embodiment, referring to FIG. 7, a motorized conveyor system 70 can be employed in such a way that cargo could be loaded from one location and the conveyor 72 used to transfer the cargo, back, deep into the cargo compartment. Hand rails 74 are utilized for maneuvering of the conveyor system while a motor 76 is used to impart motion to the system. Additionally, identifying labels can be utilized to organize the cargo and a computerized controller can be used to selectively return individual portions of cargo or selective groups of cargo back to the location of choice.
As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
