5 Patented Jan. 27, 1942 UNITED STATES -- s 2 Claims. This invention relates to external protectors for articles packed in containers, boxes or crates, such as furniture, refrigerators, radios, phono graphs, signs, and in fact any sort of article which must be kept away from the inner surface of a shipping container, and is for the purpose of preventing injury to the corners and edges of such articles. A further purpose is to provide a protector of this nature which can be stored and shipped inflat condition, but which can be quick ly and easily set up for use with various parts interengaging and holding one another in place. A difficulty with previous protectors of this character is that in order to provide sufficient thickness to give a satisfactory cushioning effect it has been necessary to assemble by adhesive be tween successive layers in their completed form and thus make them bulky and unwieldy to ship and to store until needed for use, because a set up trihedral angular structure had to be dealt PROTECT TOR, PATENT OFFICE John S. Kirby, Indianapolis, Ind., assignor to - The Hinde and Dauch Paper Company, San dusky, Ohio, a corporation of Ohio Application May 22, 1939, Serial No. 275,017 with instead of a fiat blank. My invention aims to avoid these disadvantages without detracting in any manner from the protecting properties, or from the ease of applying the protector to furni ture or other articles. In the accompanying illustrations, which show certain preferred and practical embodiments, the specimen shown is limited to a trihedral corner having relatively short sides, although it will be appreciated that the extensions beyond the cor ner may be of such dimensions as will be ap propriate to the objects to be protected and that the illustrations therefore are not intended as limitations upon the scope of the invention. In the accompanying drawings: Fig. 1 is a perspective of my improved protec tor viewed from the inside, also illustrating an intermediate stage of set-up by dotted lines; Fig. 2 is a perspective Of the same corner, as sembled, looking from the outside; Fig. 3 illustrates the blank from which the corner is made; Fig. 4 is a transverse vertical section on plane 4-4 of Fig. 1, looking in the direction of the arrows;. Fig. 5 is a vertical section on plane 5-5 of Fig. 1, looking in the direction of the arrows; Fig. 6 is a horizontal section on plane 6-6 of Fig. 1, looking downward; Fig. 7 is an inside perspective of a modified protector, Set up; w (C ) 0-0, f-f and 2-2, respectively, of Fig. 7, in the direction of the arrows; Fig. 13 is an inside perspective of another modification; Fig. 14 is the blank of Fig. 13; Figs. 15, 16 and 17 are sections on planes 5-fs, 6-6 and T-7, respectively, of Fig. 13, in the direction of the arrows; l, Fig. 18 is an inside perspective of a further 10 modification; F????????? is a perspective showing the folding of ig. 18; Fig. 20 is the blank of Fig. 18; and, Figs. 21, 22 and 23 are sections on planes , and 23-23, respectively, of Fig. 18, in the direction of the arrows. Referring first to the various blanks for pur poses of explanation, I make the blanks prefer ably from a single piece of corrugated board, 0 double wall being best for most purposes because of the good cushioning effect, and fold various portions of the blank on one another and into connection with one another as hereinafter ex plained. In the present illustrations the pro 25 tectors are formed with two or three thicknesses of double wall board for the sides, equal to four or six plies of single wall corrugated board. The panel arrangements are such as to interfit with and overlap one another in well defined manner, 30 with a mutual retaining effect upon one another. This mutual retaining effect is such that when the various panels of the protector are succes sively folded into correct mutual relation it is only necessary to hold the panel last folded in 5 Order to keep the whole corner assembly firmly together. Such holding is most conveniently done by tongues engaging into notches (examples of which are shown in Figs. 5, 7 and 13), but stapling (as in Fig. 6) or taping (as in Fig.18) 40 are alternatives. The tongue is preferred be cause it eliminates the need for a roll of tape and a moistener at the station where the corners are set up from the flat blanks, and stapling is not desirable where there is danger of scratching the 45 portion of the packed article to which the corner is applied. The specific blank of Fig. 3 comprises a main panel or base f divided by fold lines 2 and 3 (dotted in Fig. 3) forming a series of panels at 50 one end of the base and another series at one side of the base. An aperture 6 is cut into or Fig. 8 is a perspective of the same protector through the base parallel to the line. 2, and showing the folding of panels upon one another; at an appropriate distance therefrom, to receive Fig. 9 is the blank from which Fig. 7 is made; a locking tongue, in case this method of fas Figs, 10, 11 and 12 are sections on planes 56 tening is to be used. A staple It', Fig. 6, or a

6 V 2 fastening tape, similar to 85, Fig. 16, or 0, Fig. 18, might be used.???????????? The end series of panels, attached along the line ia, comprise an outer Wall 18, a top con nector 9, and an inner wall 20, which last has the tongue f extending from its free edge as shown. The inner edge 24 of the Wall 8 is in wardly offset from a projection of the hinge line f3 to allow for folding, and the panels f 9 and 20 have their inner edge 25, common to both, stepped still further inwardly along the line 9, also to allow for folding. The side series of panels, bendably connected to the base along the line 3, comprise an outer vall panel 30 to Whicha narrow top con nector 3 is directly hinged along fold line 32, parallel to 3, and an inner wall panel 33 is hinged along the outer edge to the connector 3 along a line 34. A panel 35 slightly narrower than 30 is hinged to the corner end of 30 along line 36. The left edge 37 of panel 35 is offset to the right from the end of fold line 3 to the same extent as the leftward offset of the edge 24 of panel 8. The right edge 38 of panel 35 is prolonged into panel 30, meeting the upper edge 39 of con nector 3 and nicking into the upper right corner of panel 30. The edge 39 is prolonged to the right as a crease only, between the inner vall panel 33 and a connector 4. The con nector 4 is further hingedly connected to a panel 45 which extends in the same direction as panel 33 in the blank. The left edge 4 of panel 45 continues down across the left edge of connector 4 and meets edge 39. Panels 33 and 45 and connector 4 are all terminated on the right by the right edge 49 of the entire blank. The use of connectors 9, 3 and 4, and the offsetting of the various inner edges permit fold ing of the assembly without crushing of plies, and with a square and trim appearance to the finished protector. In assembling the protector each series of panels is bent upwardly at right angles along lines 2 and 3, respectively, and then the panels of each series are Suitably interfolded to form two side walls 50 and 5, locked together at the corner. In the present illustrative embodiment each of these side Walls is of the same thick ness, and since two plies of corrugated board have been taken as the basis, the side walls will each be six plies thick. The details of the preferred method of inter folding to set the panel up according to Fig. 1 are as follows: 55 Panel 45 is folded over onto 33, with the con nector 4 acting as a double hinge line at 43 and 44 to give a flat position. Panel 35 is turned 90 around the hinge line 36, and 30 is turned 90 around the hinge line 3, thus bringing edge 37 of panel 35 down against the base f between the upper edge of 6 and the fold line f2. The unit is turned as far inward as it will go around the double hinge 34, 3, 32, which brings the panels 33 and 30 into a parallel posi tion at right angles to the base if, with panel 45 sandwiched between them. All parts are now in the position of the dotted showing of Fig. 1. To complete the assembly the panel 2 is brought down around the double hinged con nector (9, over the panel 35, with edge 25 bear ing against the face of 33 near the edge 39, and the tongue T is tucked into the slot 6, thus O completing the assembly with all parts in the full line position of Fig. 1. Thus the paniel 35 serves as an interlock to hold sides 50 and 5 at right angles to the base and to each other particularly to prevent the sides from spreading out, while the article to which the protector is applied prevents the panel 20 from lifting to free the tongues T. There is also a binding effect between the face of panel 33 near its edge, and the inner end 25 of panel 20, the end 25 being offset just enough to bear firmly upon 33 without crushing.. In describing the blank of Fig. 9, the panel 6 is taken as the first panel, connected at 54 to a side panel 55, which folds 180 onto panel 6, and is also connected at 56 to a series of panels 62 to 68 inclusive successively attached to one another by hinging creases (dotted lines) with a bridging connector 57 between the third and fourth panels, that is between 63 and 64. A tongue 58 on the outer edge of 64 is adapted to engage a notch 58 in panel 6. The fifth, sixth, seventh and eighth panels of the series, that is 65 to 68 inclusive are a collective group hinged to the upper edge of panel 62, which is the only connection between this group and the second, third and fourth panels. In detail this last group comprises a panel 65 hinged to 62, with a narrower panel 66 of the same length as the height of 63 hinged to one end of 65 and thus adjacent to but severed from the upper edge of 63. On the upper edge of panel 65 there is a bridging connector 6 by which panel 67 is attached. Panel 67 carries an extension panel 68 hinged at 59 to its outer end and paral lel to 66. Suitable clearance is provided as at 70, 7 and 72 for thickness of material in folding. The method of setting up is illustrated by Fig. 8. Panel 55 is folded 180 around its connector 54 and thus brought under panel 6. These two panels together are then turned around the connector 56 to bring both on top of 62, thus forming the base of the protector. Notch 58' is exposed. Panels 65 and 63 are brought up 90 around their respective fold lines, thus abut ting against the combined edges of 55 and 6, and against the connector 54, respectively. The protector shown in Fig. 13 is made from a blank, Fig. 14, having two parallel sets of panels and The panels f and T2 are hingedly connected side by side, with the other panels of each series hinged to the upper edges of the corresponding One of these first-named panels, but the two series are fully separated otherwise, as shown by full lines. Suitable connector strips 79, 80 and 8 f, defined by creases, are interposed where necessary to allow successive panels to be folded 180' with respect to one another, and a clearance cut 82 is made between the panes T5 and 76 to allow proper edge space for folding and matching. A notch 83 in panel 7 is adapted to receive a tongue 85 in the far edge of panel 77. Other fastenings, such as the tape 85, Fig. 16, might be used. A convenient method of setting up this specific a protector is to leave panels 73,74 flat, turn 7 and 72 completely over on top of them, then to bring 72 up 90 with respect to 7 (see Fig. 17), and at the same time turn 76 through an angle of 90 with respect to 74, and flat against the inner face of 75, which is brought up at a right angle to 3. Panel 7 is then folded down over 6 and tongue 85 is put into the notch 83, thus inter

locking the entire assembly. This specific pro tector has sides of two thicknesses of the mate rial of the blank and a base of three thicknesses. The protector shown in Fig.

7 locking the entire assembly. This specific pro tector has sides of two thicknesses of the mate rial of the blank and a base of three thicknesses. The protector shown in Fig. 18 has three walls of equal thickness, each two plies. The blank is of two symmetrical parts, consisting, of panels 9 and 92 with a hinge 90 creased between then whereby they may be folded into face to face relationship. Each of the panels 9 and 92 serves as a base to which further sets of panels and 94-96, respectively, are attached to successive connectors in One Set and in the other. The series is sepa rated from the series by a slot to permit necessary clearance of edges in setting up. The steps of folding are shown in Fig. 19, and consist, of turning 9-92 over on top of 93-94, then turning 92 up on hinge 90 at a right angle to 9. Panels 95 and 96 are each turned perpen dicular to 93 and 94 respectively with 96 against the inner face of 95. To assemble this protector, the panels 93 and 94 are left flat, and the panels 9, 92 folded 180 about the connectors 97, 98, thereby bringing 92 face down upon 94 and 9 face down upon is now bent up at 90 around the hinge line 90, and 96 is bent at 90 around the connector 00, and these parts brought to approximately the position of Fig. 19, followed by bringing panel 95 up at 90 to 93 and on the outside of 96 so that the assembly takes the form shown in Fig. 18. If it is important to maintain the set-up of the protector before it is applied, the panels 95 and 96 may be fas tended together by appropriate means, such as tape Of. - Y From the foregoing it will be seen that I have invented a corner protector made from a single blank which can be left flat until needed, and set up quickly and firmly with a few deft mo tions when ready for use, and which gives the article being packed the protection of several more thicknesses than compose the original blank.? The foregoing description, and the drawings, are to be taken as illustrative only, reference being made to the following claims to define the scope of the invention. I claim: 1. A corner protector comprising in combina tion a blank divided into a plurality of foldable panels, the first of said panels having a notch at one edge and a series of other panels hinged to the edge opposite the notch; a single panel hinged to an edge of said first-named panel be tween said notched edge and the edge to which the series is hinged; said series comprising a second panel immediately hinged to said first 3 panel, and third and fourth panels, said third. panel being hinged to said second panel parallel to the first panel hinge line, and said fourth panel being hinged to said third panel parallel 5 to the third panel hinge line and tongued on the edge remote from the hinge to engage said notch; a fifth panel hinged to an edge of the Second panel at right angles to the first and third panel hinge lines, and a sixth panel hinged to. an edge of the fifth along a line substantially in prolongation of the third panel inner hinge. line, a seventh panel hinged to the fifth on a line parallel to the second panel hinge line, and an eighth panel hinged to the seventh and ex tending parallel to the sixth; said single being foldable to overlap the first, said first and single together being foldable to overlap the second, said eighth being foldable to overlap the Seventh, said seventh with eighth overlapped being fold able to overlap the fifth, said fifth being fold able to form a right dihedral angle with the second, said third being foldable to a right dihedral angle with the second having the sixth interfacially engaged between the third and fourth. 2.
