[57] ABSTRACT A carrying handle for cardboard. cartons having two sets of opposed overlapping top flaps, including a base plate with four threaded studs equiangularly positioned on the base plate so that with the base plate appropriately positioned beneath the closed flaps each threaded fastener extends through aligned openings in two of the flaps, there being provided a top plate over the closed flaps with four apertures for receiving the threaded studs, with wing nuts on the studs for holding the plates together, and a carrying handle fixed to the top plate.
9 Claims, 3 Drawing Figures 1 V CARRYING HANDLE ASSEMBLY FOR CARTONS BACKGROUND OF THE INVENTION The manual lifting of cardboard containers of relatively large size has been a significant problem with salesmen, displayers, and others who transport the same carton between different locations. The transporting of cartons of a large size by supporting them on the shoulder is not only quite difficult, but a maneuver which is not facilitated by conventional clothing as worn by salesmen and other white-collar workers.
One solution for carrying cartons in the past is to wrap the entire carton in string and attach a removable handle to the string portions at the top of the carton. This solution has notproved entirely satisfactory because the handle assembly tends to pull over too far to one side of the carton, particularly if the article within the carton has a considerable weight.
It is a primary object of the present invention to minimize the problems noted above with the prior art.
SUMMARY OF THE PRESENT INVENTION In accordance with the present invention, a carrying handle assembly is provided that releasably attaches to the top flaps of a carboard carton and permits the carton, even though it be of considerable size, to be easily carried from one location to another by the carrying handle. l
Cardboard cartons are generally constructed so that they have four overlapping top flaps, with opposed flaps in nearly abutting relation. Basically, there are provided top and bottom plates between which these carton flaps are sandwiched to provide an excellent grip on the carton.
Toward this end, the bottom plate is provided with four equiangularly spaced upwardly projecting studs with the studs being positioned so that each extends throughtwo adjacent top flaps of the carton. In this manner, the studs extend through the grip in toto eight openings in the top flaps, two in each flap.
A top plate rests on top of the flaps and has four openings which receive the upwardly projecting studs. Wing nuts threadably engaging the studs rigidly clamp the flaps between the two plates. A handle is provided fixed to the top plate for manual carrying of the entire box or container.
The method of fixing the present carrying handle apparatus to the container also forms a partof the present invention. In order'to accurately make the receiving holes in the flaps in the proper position, the flaps are closed, and the bottom plate placed upside down on top of the flaps and the flaps marked by a pencil or pen at the location of the studs. The top plate is then removed and the pencil marks are punched through all four flaps of the carton.
The bottom plate is then turned with the studs facing upwardly and placed within the container held in place either by the article within the container or by a piece of cardboard cut the size of the inside of the container so that it fits snugly therein and supports the bottom plate near the top of the container to facilitate placement of the flaps in the closed position with the cover plate inside the container. Thereafter, one opposed set of flaps is closed over the bottom plate with the. studs projecting through each flap and thereafter the opposite opposed set of flaps are closed over the same studs.
The top plate is then placed over the projecting studs and the wing nuts fastened into position. i
It should be understood that the present handle is readily removable and may be used over and over again on different containers as desired.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a container with the carrying handle assembly according to the present invention shown in its affixed position;
FIG. 2 is a cross section taken generally along line 2-2 of FIG. 1 illustrating the carrying handle assembly and its relationship to the container flaps; and
FIG. 3 is an exploded view of a container and the'carrying handle assembly according to the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT I Referring to the drawings and particularly to FIGS. 1 and 2, a carton of conventional construction is illustrated having a carrying handle assembly 12 in its affixed position as shown in FIG. 1. Handle assembly 12 is particularly useful for manually carrying cartons 10 of considerable size and weight from one location to another.
The container 10 is seen to include side walls 15 and 16 that have projecting from the upper ends thereof flaps 17, 18, 19 and 20. The flaps l7 and 19 are re ferred herein to as opposed flaps as are the flaps 18 and 20, and when these opposed flaps are in their closed position, their ends are spaced somewhat as shown at 22 in FIG. 2.
The handle assembly consists of a bottom plate 24, top plate 25 and a handle 26 rivited as at 27 to the top plate 25. v
The bottom plate 24 is rectangular in construction and has rigidly fixed thereto four upwardly projecting threaded studs 28, 29, 30 and 31. The studs are positioned' at the corners of an imaginary square on the plate 24 and are also equiangularlly space on the plate.
The bottom plate 24 lies immediately below the lowermost flaps 17 and 19 centrally of the container as shown in FIG, 2, Stud 28 projects through openings 36 in flap l7 and 37 in flap 20. Stud 29 projects through openings 40 in flap 19 and 41 in flap 20. Stud 30 projects through openings 43 in flap l9 and 44 in flap l8, and stud 31 projects through openings 46 in flap 17 and 48 in flap 18. s
In this manner each of the studs 28, 29, 30 and 31 projects through aligned apertures in adjacent flaps so that when subjected to the upward force provided by handle 26, the aligned apertures on each stud andtheir flaps will tend to separate, but are prevented from doing soby the studs themselves, and in this manner a very rigid handle assembly is provided and no relative movement is permitted between the handle assembly and the carton or its flaps.
The top plate 25 provides the support for the handle 26 and also locks the bottom plate 24 in position.
Toward this end, the top plate 25 is generally rectangular in configuration and has apertures 50, 51,.52and 53 aligned with the studs 31, 28, 29 and 30 for freely receiving the same. For the purpose of locking the top plate 25 to the top of the flaps 18, 20 and sandwiching the flaps between the plates 24 and 25, wing nuts 56 are l7 and 19 thereby providing the necessary aligned holes in the adjacent flaps. Thereafter, the bottom plate 24 is positioned within the container with the flaps open. This is accomplished either by supporting the plate 24 on the article within the container or cutting out a piece of cardboard 60 slightly larger in size than the inside of the container 10 so that it can be snugly placed therein in the position shown in FIG. 3 to support the bottom plate 24 during assembly of the handle.
With the bottom plate 24 supported within the container, the flaps 17 and 19 are closed over their respective studs and the studs are permitted to project therethrough. Thereafter, the flaps 18 and 20 are closed over the same studs. The top plate is then placed over the studs with the studs projecting therethrough and the wing nuts 56 threaded to the studs firmly attaching the top plate in position and clamping the flaps between the plates 24 and 25. The carrying handle is then ready for use, and may be removed simply by removing the wing nuts 56 and disassembling the handle in the reverse order described above for assembly.
