United States Patent 3,233,753 PGRTABLE SHIPPING CONTAINER Samuel Rich, Oak Park, Mich., assignor to Acorn Aluminum Products Company Inc., Warren, Mich. Filed Jan. 23, 1963, Ser. No. 253,334 4 Claims. (Cl. 214-10.5)
This invention relates to a portable shipping container for transporting sheets of glass.
An object of this invention is to provide a reusable, portable, shipping container for large sheets of glass, which container is additionally useful as a manually movable vehicle to move and store the sheets of glass packed therein.
A further object of this invention is to provide a compact container which is adapted to support a large quantity of flat sheets of glass, standing on edge, in face to face relationship, within two separate container sections, and having rollers, upon which the container may be rolled, and means for removably fastening the container upon a wood truck or railroad car platform.
These and other objects and advantages of this invention will become apparent upon reading the following description, of which the attached drawings form a part.
In these drawings:
FIG. 1 is a perspective view of the container.
FIG. 2 is a perspective view looking down into the container, but with the front panels removed.
FIG. 3 is a front elevational view of the container, and
FIG. 4 is an end view taken in the direction of arrows 4-4 of FIG. 3.
FIG. 5 is a fragmentary, enlarged view of a portion of the container, taken as if in the direction of arrows 55 of FIG. 4.
FIG. 6 is a perspective, fragmentary view of a portion of the container and an unlocking and transporting tool used therewith.
FIG. 7 is an elevational view of the container lower portion, showing the container moved by the tool.
FIG. 8 is a perspective view of the support base and framework.
The container 10 is built upon a bottom frame 11 (see FIG. 8) which consists of horizontally arranged side rails 12 and end rails 13 and 13a joined together at their ends to form a rigid frame. A number of cross-slats 14 are arranged transversely of the frame and secured to the side rails 12 and upon the slats are secured wedge-shaped blocks 15.
Conventional support rollers 16 are secured to the frame near the end frame rail 13a and vertical support posts 17 are secured to the frame near the end rail 13, the posts terminating in horizontally arranged plates or pads 18 having nail holes 19 formed therethrough.
A horizontally extending, centrally located tongue 20, having a central hole 21, is formed on the end rail 13.
Secured to each of the end rails is a vertically arranged A-frarne 23 formed of a pair of legs 24 joined together at their upper ends where a hook 25 is secured as by welding, and having a cross-bar 26 which extend beyond the legs 24. The apices of each of these A-frames are joined together by a cross-strip 27 to form a rigid unit. In addition, a pair of outwardly extending arms 18, preferably formed of angle iron, is secured near the upper ends of each of the A-frames with the arms terminating in vertically arranged pads 29 which are arranged in the same vertical planes as are the side rails 12.
The horizontal frame 11, the A-frames, and the arms 28 and cross-strip 27 may all be formed of metal sections which are welded together to form a rigid skeleton for the container.
The container is formed with two separate, oppositely opening sections, arranged back to back, with each section having a back wall 30 whose side edges are secured to the A-frame legs 24 and whose lower edge is rested upon the slats 14 so that the back panels tilt away from the vertical and upwardly toward each other. Each section also has a horizontally extending floor 31 fastened to the wedge shaped blocks 15 so that the floors tilt downwardly towards their respective back panels at right angles thereto. Vertical end walls 32 are arranged at the ends of the floors and are fastened to the arms 28, the cross-bars 26 and the framework end rails 13 and 13a. Preferably, the back panels, floors, and end panels are all formed out of wood.
In use, large sheets of glass 35 having conventional, protective edge bindings 36 formed of cardboard or packing material are rested upon the floors 31 and tilted back against the back panel 30. Thus, the glass sheets are supported on their lower edges and are confined between the side panels 32. Since the sheets tilt backwardly, they can be left within the container without falling out while the container is stationary.
To hold the group of glass sheets 35 within the container sections while transporting the container, each container section is provided with a front, removable panel 37, preferably in the form of a large sheet of plywood or the like which is provided at its lower edge with downwardly extending pins 33 arranged to seat into holes 39 formed in the floor 31. The holes 39 are arranged in two rows so that the panel may be selectively located closer to or farther away from the back panels 30, depending upon the number of glass sheets within the container to thus tightly compress against the sheets. Secured to the upper horizontal edges of each of the front panels 39 are cross-bars 443 preferably formed of right angle section metal and having end extensions having bolt holes through which bolts 41 are placed to extend into one of a number of holes 42 formed in the respective arms 23 for bolting the upper edges of the panels 37 to the container. Because of the number of holes 42 in the arms and the nrnnber of holes 39 in the floors, the positioning of the panel 37 may be easily varied.
In operation, the container sections are loaded with sheets of glass 35, the front panels 37 are placed in position to compress the glass between the front and back panels of each section, and the container may then be lifted by its hooks 25, using a suitable crane, and placed upon a wood support platform 43 of a truck or railroad car. Once positioned for shipment, nails 44 are inserted through the holes 19 in the pads 18 to nail and thereby lock the container to the support platform. Upon reaching its destination, the nails are pried loose and the container may be lifted off the support floor and moved to the place where it is to be unloaded.
To expedite the removal of the rails 44 and the movement of the container, a tool 45 is provided (see FIGS. 6 and 7). The tool is in the form of a base member, 46 mounted upon rollers or wheels 47, and to which is connected a long curved bar or pole 48 terminating in a hand grip 49. An upwardly curved stud or pin 50 is secured to the front of the base 46.
In use, the tool is rolled up to the tongue 20 of the end rail 13 and its curved bar is tipped rearwa-rdly upon the rollers 47 until the stud 5t enters the hole 21 in the tongue. Then by further tipping it back, the bar 48 functions as a lever, pivoting about the wheels 47, to lift the end rail 13 upwardly and thus pull the nails free from the support floor. (See FIG. 7.) The tool can then be used as a dolly to pull the container upon the rollers 16 of the container and the rollers 47 of the tool. Thus the container may be rolled to the particular place where the glass is needed, the panels 37 may be removed, and the container may serve as a supply bin from which the sheets of glass may be removed one by one as needed.
This, invention may be further developed within the scope of the following claims. Accordingly, it is desired that the foregoing description be read as being merely illustrative of an Operative embodiment of this invention and not in a strictly limited sense.
