ABSTRACT OF THE DISCLOSURE
A cornerboard for a pallet is provided which is fabricated from a suitable material; in one embodiment it is molded of a plastic and in another it is made of sheet steel sections. the cornerboards may be provided with a variety of interlocking sections and spacer members so that packages of different sizes can be accommodated by selecting the proper length of the sections and/or spacers.
Description
SU~MARY OF THE INVENTION
-Many materials, such as frozen foods, are sold in rela-tively small cartons and in order to handle these expediously, they are placed on pallets. In order that the pallets can be handled and stored it is ordinarily necessary to pro~ide some sort of corner structure for the palleted goods to keep the goods upright and to prevent them from sliding off the pallets.
In the past, it has been universal practice to hold goods by the use of ordinary boards. Two boards~are nailed together at a right angle to form a corner pair and four of such corner pairs are placed at the corners of the loaded pallet and held together with some form of stxap.
The cornerboards used in the past ha~e not been fully satisfactory, primarily in that they do not properly protect the goods on the pallet. Such board~ frequently allow the gvod~ to saq so that much merchandise is lost. Further, the boards must be assembled by hand and cut to fit the particular load which i8 to be placed on the pallet.
In accordance with the pr0sent invention, an improved corner structure is provided for pallets which contain two or more interlocking sections to~ether which may be used with spacer elements.
The corner structures of the present invention are much ~tronger than conventional boards so that better protection is given to the load and also ACt as load~bearing elements when pallets and their loads are stacked.
~ ~urther ~eature of the pre~ent in~ention is that the top section, and in some instances the bottom section as well, are provided with a cap which ~urther protects the contents of khe pallet.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to Figures 1-5 of the drawings by re~erence characters there is shown a pallet 7 having a load of boxes 9 thereon. The boxes 9 have a rectangular configuration and have been stacked to fit the pallet 7.
In accordance with the present invention four corner elemènts generally designated 11, 13, 15 and 17 are placed at the f4ur corners of ~he loaded pallet and a fle~ible skrap 19 is employed to hold the cornerboards together and maintain the pallet load in a desi~ed configuration. Although only a singl~
strap 19 has ~een shown, in many instances two or even more straps might be used around the load.
Since the four cornerboards are identical, only one will be described in detail. Thus, referring to Figures 2 -through 4 the cornerboards included a top member generally designated 21.
The merr~er 21 has a top cap 23 which has a ~lat upper surface 25 so that the flat upper surface covers the corner of a pallet load. The top cap also includes a downwardly extending portion 27 which extend6 outwardl~ somewhat beyond the corner of the pallet. Also extendiny downwardly from the cap top cap 21 is the riyht angled fin 29 which include6 the elernents 31 and 33 which are formed at a right angle to each other. The elements 31 and 33 are foxmed o thin sections.
Below the top member 21 is a spacer member yenerally designated 35. This mer~r has two walls 37 and 39 which are located at right angles to each other and formed within these -4~
walls is a right angle slot 41 which is complementary to the fin 29 so that -the fin 29 can pass through this slot.
Situated below the spacer element 35 is the bott~m member generally designated 43. This member has two walls 45 and 47 with a slot 4g which is complementary to the fins 29. However, the slot 49 terminates short of the bottom as is shown at 51.
Thus the bottom member 43 has a slot openirlg at the top but is ~olid at the bottom. Fin 29 passed down through slot 41 in me~ber 35 and then into slot 49 in member 43.
In some instances, it would be desirable to provide a structure which permits the use of a member like the top member 21 on the bottom of the pallet. In such a situa~ion, an i~ter-mediate member is provided as is showrl in Figure 5 having outer and inner walls 53 and 55 respectively with a slot 57 at the bottom. If such an intermediate member is used, it is obvious that a member such as that designated 21 could be inverted and . .
used on the bottom of the stack.
One eature of the present invention is that members can be used interchangeably to pxovide for varying heights of stacks of goods piled on the pallet. Thus the member 35 could be higher or lower depending on the particular height of the good~ piled on the pallet. For instance, one could use the members 21 a~d 43 on various loads on pallet~ b~ providing coll~r~ 35 o~ varying height. In fact, in some instance~ one could eliminate collar 35 altogether and merely use the top member 21 and the bottom member 43.
Another embodiment of the invention i~ shown in Fi.gures 6-9. In this embodiment of the invention, the ~tructural material is preerably sheet steel and the parts are abricated by bending and welding operations. Hvwever, other construction materials may be used.

In Figure 6 a pallet is shown, as before, having four corner posts, generally designa~ed 60, 62, 64 and 66. Since all of these posts are i~entical, only one is described in detail.
As is best shown in Figure 7, the corner suppor~ consists of a top member, generally designated 68, and a bottom member, generally designated 70. Intermediate members may or may not be used and two are shown in Figure 7, generally designated 72 and 74. The intermediate members 72 and 74 have been shown o~
equal hei~ht, but it is not necessary that ~hey be of the sc~me height and two or more members might be used of different heights.
Top member 68 consists o~ an angle iron, having the faces 76 and 78 forming a right angle to each other. These could be fibricated fxom two sheets welded along the junction 80 but normally they w~uld be bent from a single sheet of steel. A
top member 82 is fastened to a side member 76 and 7~, pre~er-ahly by welding.
The bottom member 70 i8 basically of the same structure having the side plates 84 and 86 which form a right cmgle to each other and whiGh have a triangular bottom plate 88 cor-responding to the top plate 82. The side plates 84 and 87 have inturned lip8 90 and 92 respectively which orm bights 94 and ~6. The bights 94 and 96 are of a sufficient wldth to form a tight fit wlth the plat~s 76 and 78 and the inturned lips ~0 and 92 are sufficiently lorlg to support the plates 76 and 78 in a substantially rigid manner.
In many inatances, thP top member 68 and the bottom member 70 can be selected of a suitable si~e so that it is not neces-sary to use any intermediate spacer members. Thus, the sid~
.
7~ :
members 76 and 78 could be merely slipped into the bights 9~and 96 and pressed down over the corner of the pallet, it being underætood, of course, that the corner structures would form load-bearing structures so that another pallet could be stacked on top of one shown without compressing the contents of the pallet itself. ~i In order to provide for more versatility so that it is not necessary to fabricate the side members to the exact size needed, one or more intermediate spacer members such as 72 and 74 may be employed. Each spacer member consists of the sides 98 and 100 which are set at a right angle to each other.
Inturned lips 102 and 104, corresponding ko the inturned lips 90 and 86, are provided so that each of the spacer elements is of the same general structure as the bottom element except that ~- it is shorter and does not have a bottom plate. As is shown best in Figure R, the spacers 7~ and 74 are employed to build the corner post up to the desired height and to make a load-bearing structure of it so that any load from above is borne by the corner members and not by the load on the pallet.
Many variations can be made in the ~xact structure shown without departing from the spirit of this invention.

Referring now to Figures 1-5 of the drawings by re~erence characters there is shown a pallet 7 having a load of boxes 9 thereon. The boxes 9 have a rectangular configuration and have been stacked to fit the pallet 7.
In accordance with the present invention four corner elemènts generally designated 11, 13, 15 and 17 are placed at the f4ur corners of ~he loaded pallet and a fle~ible skrap 19 is employed to hold the cornerboards together and maintain the pallet load in a desi~ed configuration. Although only a singl~

Since the four cornerboards are identical, only one will be described in detail. Thus, referring to Figures 2 -through 4 the cornerboards included a top member generally designated 21.
The merr~er 21 has a top cap 23 which has a ~lat upper surface 25 so that the flat upper surface covers the corner of a pallet load. The top cap also includes a downwardly extending portion 27 which extend6 outwardl~ somewhat beyond the corner of the pallet.

Thus the bottom member 43 has a slot openirlg at the top but is ~olid at the bottom. Fin 29 passed down through slot 41 in me~ber 35 and then into slot 49 in member 43.
In some instances, it would be desirable to provide a structure which permits the use of a member like the top member 21 on the bottom of the pallet. In such a situa~ion, an i~ter-mediate member is provided as is showrl in Figure 5 having outer and inner walls 53 and 55 respectively with a slot 57 at the bottom.
