Toledo, Ohio, assignors to Owens-Illinois Glass Company, a corporation of Ohio Fiied Dec. 15, 1%1, Ser. No. 159,356 3 Claims. (Cl. 229-14) This invention relates generally to corner pads, and more particularly to a self-locking corner pad.
This invention is directed primarily to a corner pad formed of foldable sheet-like material, such as corrugated paperboard or board formed from laminate of paper and foamed plastic. The corner cap of this invention is especially designed to protect corners of panellike or slab-like articles, such as plate glass mirrors or curtain wall panels. The corner pad is characterized by having a pair of spaced apart side Walls and connecting ends walls of triple ply thickness.
It is an object of this invention to provide a simple, inexpensive corner pad.
Another object of this invention is to provide an improved self-locking corner pad having end walls of triple ply thickness.
A further object of this invention is to provide an improved, self-locking corner pad having a pair of spaced apart side walls.
The specific nature of this invention as well as other objects and advantages thereof, will become apparent to those skilled in the art from the following detailed description, taken in conjunction with the annexed sheets of drawings on which, by way of example only, the preferred embodiment ofthis invention is illustrated.
In the drawings:
FIG. 1 is a perspective view of the blank used to form the corner pad of this invention;
FIG. 2 is a perspective view of a partially assembled corner pad having one side Wall folded into place;
FIG. 3 is a perspective view of a partially assembled corner pad showing both side walls folded into place;
FIG. 4 is a perspective view of a nearly assembled corner pad; and
FIG. 5 is a side sectional view of an assembled corner pad with one side wall removed.
Referring to FIG. 1, the blank, which is folded to form the corner pad of this invention, is preferably formed of foldable sheet-like material, such as corrugated paperboard or what is referred to as foam board. Foam board comprises a pair of kraft paper outer liners laminated to a core of foamed plastic material.
The blank B comprises a sheet of material which has been cut and scored to provide a series of foldably connected panels. A pair of side wall panels and 11 are foldably connected along score lines 12 and 13, respectively, to outer end panels 14 and 15. The outer end panels are foldably connected together along score lines 16. Intermediate end panels and 21 are foldably connected along score lines 18 and 19 to side wall panels 10 and 11, respectively. The score lines 18 and 19 are aligned with each other and with the score line 16'.
A pair of inner end walls 22 and 23 are foldably connected along double score lines 24 and 25, respectively, to the outer end edges of the outer end panels 14 and 15. The term double score line as used herein means a pair of parallel score lines, spaced apart a distance approximately equal to the thickness of the material used.
Referring to FIGS. 2-4, the corner pad is erected by folding the side wall 11 normal to its associated outer end panel 15, and then folding the intermediate end wall shorter than the other end panel.
21 normal to its associated side wall 11. The same procedure is repeated with respect to panels 10, 14 and 20. The outer end walls 14 and 15 are then folded normal to each other to achieve the structure shown in FIG. 3.
The inner end panels 22 and 23 are then reversely folded into the interior of the corner pad to complete the erection of the corner pad. From FIG. 5, it may be noted that one of the inner end panels 23 is made slightly This permits the shorter inner end panel 23 to abut against the longer inner end panel 22 and lock it in place. The shorter inner end panel 23 is frictionally maintained in place by hearing against the other inner end panel 22. This is accomplished by making the inner end panel 23 sufiiciently long so it will slightly compress the lower edge of the inner end panel 22.
It will, of course, be understood that various details of construction may be modified through a wide range without departing from the principles of this invention, and it is not, therefore, the purpose to limit the patent granted hereon otherwise than necessitated by the scope of the appended claims.
In the claims:
1. A corner pad formed of foldable sheet-like material comprising,
(1) a pair of outer end walls foldably connected together along a score line, said outer end walls folded normal to each other,
(2) a pair of side walls foldably connected to opposite side edges of said outer end walls, said side wall folded'normal to their respective end walls to lie in parallel spaced apart relation with each other,
(3) a pair of intermediate end walls foldably connected to the edges of said side walls, said intermediate end walls folded normal to their respective side walls to lie in face-to-face relationship with one of said outer end walls, and,
(4) a pair of inner end walls foldably connected to the end edges of said outer end walls, said inner end walls reversely folded to overlie said intermediate end walls to lock said side walls in place, said inner end walls extending into abutting relation with each other.
2. A corner pad as defined in claim 1, wherein one of said inner end panels abuts the intermediate end panel disposed perpendicular to it, and the remaining inner end panel is arranged to abut and compress the lower end of said one inner end panel.
3. A corner pad formed of foldable sheet-like material, comprising:
(1) a pair of outer end walls foldably connected together and folded normal to each other;
(2) a pair of oppositely disposed, parallel side walls, each of said side walls foldably connected to the side edge of one of said outer end panels;
(3) a pair of intermediate end walls, each of said intermediate end walls being disposed in face-to-face contact with one of said outer end walls, each of intermediate end walls being foldably attached to one of said side walls; and,
(4) a pair of inner end walls, said inner end walls disposed in face-to-face contact with one of said intermediate end walls, said inner end walls being toldably attached to one of said outer end panels, said inner end walls arranged to have respective end edges in abutting relation.
