McClive, Kenmore, N.Y., assigner to Eastern Fabricating Co., Inc., lualio, N Y. Filed Jan. 11, 1960, ser. No. 1,498 2 Claims. (Cl. 229-14) This invention relates to improvements in padding of articles to protect them during shipping or handling, and particularly to corner pads for protecting the corners of articles.

It is the present practice to make up folded corner pads of corrugated cardboard which are relatively firm but have limiting cushioning values because they are not able to stand continued shocks without some breakdown, and also constant weight upon such padding materials causes a permanent set so that these padding materials fail to afford the desired protection to the article to which they are applied. There are also padding materials made of soft, readily flexible, felted, brous materials which are easily torn or otherwise damaged and which do not lend themselves readily to the packaging of some articles.

It is consequently an object of this invention to provide a combination pad made of layers of a board-like, foldable, semi-rigid material, such for example as corrugated cardboard, and a loose, readily flexible, iibrous material resembling felt which may, for example, be made of wood fibers, the felt-like material arranged in direct contact with the article to be protected and the board-like material arranged `on the exterior thereof `so that blows or shocks received on the composite cushioning material are spread by the board-like material over a substantial area of the felt-like material to `decrease the effect of impacts or blows on the article to be protected.

Another object is to provide a combination pad of this type having three Walls to lit over a corner and having the walls formed of alternate layers :of the board-like material and felt-like material, with the latter material arranged on the inside of the walls for contact with the article to be protected and having other layers of felt-like material interposed between layers of board-like material.

It is also an object of this invention to provide a corner pad of this type which is made of a single sheet of each material which can be placed one upon another and readily folded or bent into the corner pad shape.

-In the accompanying drawings:

FIG. l is a perspective view of an article to be protected having corner pieces embodying my invention applied to the upper corners thereof and having a carton or container in position to be placed over the article.

FIG. 2 is a perspective View thereof showing the article after the container has been placed thereon and inverted with additional corner pieces placed over the other corners of the article exposed by inverting the same.

FIG. 3 is a face view of a board-like material.

FIG. 4 is a face View of the felt-like material in sheet form.

FIG. 5 is a face View showing the felt-like material positioned on a portion of the board-like material and having a portion of the board-like material folded over a part of the felt-like material.

FIG. 6 is a face view showing the corner pad after the next fold.

FIG. 7 is `a perspective view of the materials after another fold.

FIG. 8 is a perspective view of the finished corner pad.

Referring first to FIGS. 3-8, the board-like material is out into the form shown in FIG. 3 including two projections 8 and 9 separated by a slot 10, the projections 8 and 9 extending outwardly from a body portion 11 having a strip 12 extending outwardly from a side there- 3,063,613 Patented Nov. 13, 1962 of. This board-like material may be made of any suitable semi-rigid material which is capable of being folded -or creased, such for example as cardboard or corrugated paper board.

FIG. 4 shows a readily flexible sheet of `felt-like material comprising abody portion 1S which is longer than the body portion 11 of the board-like material and two

projections

16 and 17 extending outwardly therefrom and separated by a slot i18. This sheet of material may be maderof any soft, readily flexible padding material which may be -made of felted fibers of wood, cotton, cellulose fibers, Wadding or other fibrous materials. This mate.- rial can be readily torn or damaged when used by itself and consequently in accordance with my invention, I provide a combination of this soft, fibrous material with the board material in such a manner that the felt-like material will be in direct contact with the article to be protected and with the boardelike material forming a backing for the librous material.

In order to form the two layers -shown in FIGS. 3 and 4 into a corner pad, the felt-like layer is first placed over the board-like sheet in such a manner that the two

projections

16 and 17 lie over the corresponding projections 8 and 9 of the board-like material, as clearly shown in FIG. 5, and the arm or extension 12 which extends to one side of the felt-like material, is then folded over across the part of the body portion 15 of the felt-like material which is nearest to the

extensions

16 and 17. A part of the body portion 15 will then extend beyond the body portion 11 of the board-like material and this part 15 is then folded across the face of the projection 12. The body portion 11 of the board-like material is then bent or folded along an edge of the arm or projection 12 to extend approximately perpendicular to the extensions 16 and '17 so that the parts occupy the positions shown in FIG. 7. The bent-over parts of the body portions 11 and 1S are then bent or folded transversely of their lengths at 20 while the two projecting parts at opposite sides of the

slots

10 and 18 are placed one above the other, thus producing the completed construction shown in FIG. 8, in which the bend 20 is shown in the

body portions

11 and 15.

The result of this formation is that all of the inside Afaces of the three Walls `of the corner piece are of soft, felt-like material which will then be in contact with the article to be protected and each wall also has in addition to the inner layer of soft, flexible material, a packing layer of the board-like material, then another layer of the felt-like material on the outer face of the board-like material, and another board-like material on each of the outer walls of the corner piece.

As a result of this construction, the inner layers of soft, ilexible material which bear directly against the corner portions of the article to be protected are backed by panels of the cardboard or other board-like material on the exterior of which another layer of soft, readily flexible, fibrous material is arranged which in turn is backed by the board-like material. This structure had a number of advantages, in that any blows or jars that might be received on the corner pad will be transmitted by the exterior board-like material over an enlarged portion of the intermediate felt-like material, and this material in turn will transmit such blow or jar to the inner, board-like material, which further distributes this shock to the inner layer of felt-like material over a still greater area. As a result, the chances of damaging the article to be protected are greatly reduced and also the corner pads retain most of their resilience, and breakdown or settling of the felt-like material after the article rests on the corner pads for an extended period of time is greatly reduced.

In the use of the corner pads herein described, the walls of these pads may be secured together in any suitable manner to hold the parts of the corner pads in the position shown in FIG. 8, and this may be :accomplished by .tape or any other fastening means (not shown) which of course will be positioned so as to avoid any contact with the article to be protected. The corner pads are then placed on the four corners of an article 2S, which may ibe an article of furniture, a metal or wooden cabinet, electric or electronic devices and the like. A shipping case 27 of any usual or suitable construction is inverted and placed over the article 25 with the four corner pads arranged thereon and is slid downwardly over the article. The case or container with the article therein is then in- Vvertedas shown in FIG. `1, whereupon additional corner pads according to my invention may be readily inserted into the spaces between the corners of the article 25 and the shipping case 27. The lids or covers of the shipping case or container may then be folded over in the usual manner for completing the packaging of the article. My improved corner pads may of course be used in any other manner.

It will be noted that during the packing of an article in a shipping box or -container 27, only the board-like, outer faces of the corner pads are exposed to abrasion resulting from the placing of the package over the article as vshown lin FIG. l and the placing of the pads between the article and the box `so that the` felt-like material is protected against damage. The board-like outer material has ample resistance to abrasion.

The pads shown conform to existing freight packing specifications and eliminate the need for covering the article with a non-abrasive cushioning material since the corner pads embodying this invention have the nonabrasive material in contact with the surface of the article to be packaged. The corner pads further reduce the weight of the packaging which would result from using only corrugated paper pads.

The corner pads are very easily folded and consequently it is preferred to ship them in flat form, as shown in FIGS. 3 and 4. The persons doing the packing then place one Iilat layer on another and can quickly fold the two layers of material as shown in FlGS. 5 8 to produce the corner pad shown in FIG. 8. It will be noted that the felt-like material will be sured in correct relation to the corner pad due to the folds.

While I have shown my improved pad formed to extend about three surfaces of an article, it will be obvious that it may extend about two or morev surfaces. lt will also be obvious that my improved pad may have additional alternate layers of board-like and felt-like materials. It will be understood that various changes in the details, materials and arrangements of parts which have been herein described and illustrated in order to explain the nature of the invention may be made by those skilled in the art, within the principle and scope of the invention as expressed in the appended claims.
