2 Claims. (Cl. 229-14) This invention relates to means for supporting apparatus for shipment and more particularly to the support of apparatus with minimum expense and with maximum safety and efficiency.

In an exemplary application or embodiment of the present invention, a television receiver having both cabinet and receiver apparatus is supported within a container for shipment. To this end, a palletized structure underlies the cabinet to support the cabinet bottom wall in spaced relation to the cabinet bottom. This palletized structure may also carry means upstanding therefrom for engaging lower portions of the front wall, rear Wall and side walls of the cabinet to hold such walls in Y spaced relation to the inner surfaces of the vertical walls of the container.

According to the features of the present invention, there is herein provided a new and improved support structure which may be disposed over the cabinet top and may carry means depending therefrom for engaging upper portions of the front wall, rear wall and side walls of the cabinet to support the same in spaced relation to the vertical walls of the container and also to protect the edges of the cabinet at the intersections of the top wall with the front wall, rear wall and side walls.

An important feature of the present invention relates to the use of a single sheet of material folded in such a manner as to provide reinforced tubular cushioning supports about a central panel.

According to still other features of the present invention, new and improved means have been provided for rigidifying the tubular supports to eliminate the former requirement of inserting inserts into the tubes to rigidity the same and in this manner reduce the construction and assembly costs of the cushioning support structure.

Accordingly, it is an object of this invention to provide a new and improved article-support structure particularly adapted for cushioning and supporting an article within a container.

Yet another object of the present invention is in the support of an article within a container utilizing a new and improved cushioning support construction to provide a light-weight, compact, simple and inexpensively manufacturable structure which supports the article with maximum safety and efficiency.

According to a specific featurevof the present invention, tabs are cut out of the tubular supports at spaced intervals and turned inwardly into the contines of the tubular support to rigidify the same.

Still another specific feature of the present invention relates to cutting out tabs from different walls of the tubular support and turning the tabs in back to back relation and securing them together thereby rigidifying the tubular Supports.

Yet another important feature of the present invention relates to the particular manner in which cushioning pads have been provided by slitting the central sectional panel and deforming the slit portions to provide cushioning supports adjacent the reinforced tubes.

ice

According to still other features of the present invention there is provided an article cushioning structure comprised of a foldable sheet of a sturdy paper-like material having a central portion and having marginal edge por tions bounding four sides of the central portion with three of the marginal portions being folded under with each of the three marginal portions providing four flapsl defining walls which are disposed in angular relation to one another defining a box-like tubular leg, the outermost aps of the respective tubular legs being return bent in face to face retained engagement with the cen tral portion, reinforcing truss portions internally conlined within the tubular legs, the fourth marginal portion having intersecting slits generally at right angles to one another providing cut out blank portions between the tubular legs with the blank portions being folded into multi-layered box-shaped cushioning pads.

The reference numeral 10 generally designates a shipping container which may house a television receiver 11. The container 10 may comprise a front wall 12, a rear Wall 13, side walls 14 and 15, a top defined by a first pair of flaps 16 and 17 extending inwardly from the top edges of the side walls 14 and 15, respectively, and a second pair of

flaps

18 and 19 extending inwardly over the flaps 16 and 17 (Figure 1) from the top edge of the front wall 12 and the rear wall 13 respectively. The container 10 is provided with a bottom defined by flaps 20 and 21 extending inwardly over the lower edges of the side walls 14 and `15, respectively, and flaps 22 extending inwardly from the lower edges of the frontand rear walls 12 and 13 under the flaps 20 and 21.

The television receiver 11 may comprise .a cabinet generally designated by reference numeral 23 which may comprise a front wall 24, a top wall 25, a bottom Wall 26,

side walls

27 and 28 and a removable rear wall 29. Receiver apparatus is installed within the cabinet 23 which may comprise a chassis 30 disposed on the upper surface of the cabinet bottom wall 26.

To support the receiver 11 within the container 10, top and bottom support structures generally designated by

reference numerals

31 and 32 are provided. The bottom support structure is described in detail in my copending application entitled Method and Means for Supporting Apparatus for Shipment,'Serial No. 430,381;

3 led May 17, 1954, now Patent No. 2,895,661, issued July 2l, 1959.

It is believed the manner' of construction of the top support structure 31 will be best understood` from a step-by-step description of the construction thereof. In general, each of the

support structures

31 and 32 may be formed from a single blank of relatively'rigid formsustaining sheet material and preferably of an inexpensive expandible material such as paper board, ber board or the like. The support structures are formed by making bends at score lines which may be scored by marking the blank or preferably by actual indentation of the blank, especially when the blank is of paper board or a like material, but it will be appreciated that marking or indentation is not necessarily required and the terms scoring and score line are therefore used in a figurative sense to indicate the position of the bends.

Before proceeding with a step-by-step description with the method of construction, a general description of the top support structure 31 is believed to be in order. The top structure 31 may comprise a section 33 for engaging the upper side of the cabinet top wall 25, a generally tubular support means 34. for engaging between an upper portion of the cabinet front wall 24 and an opposed inner surface portion of the container front wall 12, generally tubular support means 35 and 36 for engaging upper end portions of the

cabinet side walls

27 and 28, respectively, and supporting the same in spaced relation to opposed surface portions of the container side walls 14 and 15, and a pair of generally tubular support means 37 and 38 for engaging upper end portions of the rearward cabinet wall 29 and support the same in spaced relation to opposed inner surface portions of the container rear wall 13.

In Figure 3, reference numeral 50 designates a blank from which the top structure 31 may be formed. To form the tubular support means 34 which, as desired above, engages an upper portion of the cabinet front wall 24 and a facing inner surface portion of the container front wall 12, a score line 51 may be located parallel to and at a first predetermined distance inwardly from one edge 52 of the blank 50 to define a section 53, a score line 54 may be located parallel and at a distance spaced inwardly from the score line 51 a distance substantially less than the aforesaid tirst predetermined distance to define a section 55, a score line 56 may be located parallel to and spaced inwardly from the score line 54 a distance greater than the last aforesaid distance to dene a section 57 and a score line 58 lmay be located parallel to and spaced inwardly from the score line 56 by a distance slightly less than the aforesaid second predetermined distance (by about the thickness of the sheet material) to define a section 59.

The blank 50 may be bent at the score lines 51, 54, 56 and 58 so that the section 59 extends downwardly at right angles to the base section 25 with the section 57 projecting outwardly from the lower end of the section 59 and generally in parallel relation to the section 25, with the section 55 extending upwardly from the outer edge of the section 57 (at the score line 54) in parallel aligned relation to the section 59, and with the section 53 extending inwardly from the upper edge of the section 55 over a portion of the base section 25. Mosty preferably, this portion ofthe section 53 may be adhesively secured by glue and the like g to such portions of the section 33.

To form the tubular support means 35 and 36 which, as described above, engage between end portions of the

cabinet sides

27 and 28, respectively, and inner surface portions of the container sides 14 and 15, respectively, score lines 60 and 61 may be located parallel to and at first predetermined distances inwardly from opposite edges 62 and 63 of the blank 50 to define

sections

64 and 65, score lines 66 and 67 may be located parallel to and at second predetermined distances inwardly from score lines 60 and 61 to define

sections

68 and 69,

score lines

70 and 71 may be located parallel to and at distances substantially less thanV the aforesaid first predetermined distances from the score lines 60 and 61 to define

sections

72 and 73, and score lines 74 and 75 may be located parallel to and at distances slightly less than the aforesaid second predetermined distances (by about the thickness of the sheet material) from the

score lines

70 and 71 to define sections 76 and 77.

The blank 50 may be bent at the

score lines

60, 61, 66, 67, 7G, 71, 74 and 75 so that the sections 76 and 77 project downwardly at right angles from the opposite edges of the base section 33 with the

sections

72 and 73 projecting outwardly from the lower edges of the seetions 76 and 77 in parallel relation to the base section 33, with the

sections

68 and 69 projecting upwardly from the outer edges of the

sections

72 and 73 in parallel aligned relation to the sections 76 and 77, and with the

sections

64 and 65 extending inwardly from the upper edges of the

sections

68 and 69 over edge portions of the base section 33. Most preferably, the

sections

64 and 65 may be adhesively secured, by glue and the like g, to such edge portions of the base section 33.

Joints are provided between the support means 34 and and the support means 35 and 36 by cutting the blank to an appropriate shape as illustrated in Figure 3. To this end, the support means 34 is provided with inner and outer spaced

notches

78 and 78a at opposite ends thereof. The support means 35 and 36 are provided with notches 79-79. Hence, when the tubular support means 34, 35 and 36 are folded into position they may be interlocked with only one thickness of sheet material extending above and in overlying engagement with the section 33. To this end, the sections or

wall portions

53, 64 and 65 are interlocked and are in overlying abutting face to face secured relation with respect to the section 33. Suitable adhesive such as glue may be used to maintain the

walls

53, 64 and 65 in assembled relationship with respect to section 33.

It has been found that the tubular support means 34, 35 and 36 are very easy to form in the manner as above described, requiring a minimum amount of material, and yet support the cabinet 23 with maximum safety and eiiiciency. The reason for the improved safety and efiiciency of support may be best understood by an analysis of the forces supplied to the support means 35, for ex'l ample, as viewed in Figure 2. With forces applied to the section 76 to a force tending to move the cabinet 23 toward the side wall 14, such forces will be split between the sections 72 and the portion of the section 64 in aligned relation with the section 72. These forces will be applied to the ends of the section 68 and may be evenly distributed over the inter-engaging surface portions of the section 68 and contain a side wall 14. This even spliting of forces is, of course, desirable to achieve maximum strength with a minimum thickness of material. With the forces applied against the corner defined by the

sections

64 and 68, the vertical component of such force will tend to tilt the structure about an axis approximately at the upper end of the section'76 to apply such components through the section 68 to the section 72. The horizontal component of such force will be applied principally through the section 64. Accordingly, such a force tends to Iapply equal forces through the

sections

64 and 72. It may further be Vnoted that with the portion of the section 64 overlying an edge portion of the base section 33, additional protection is provided at the corner between the top wall 25 and the side wall 27.

It is not essential, but highly desirable, that the tubular means 35 and 36 may be packed with cut out tab means 80. The ends of the tabs are turned as is shown in Fig. 7 and adhesively secured by means such as glue at g to the section or tubular side wall 72. These tabs 80 have -a configuration which corresponds to the bore of the tubular cushioning means 35 and 36. These tabs engage in nested engagement continuously about ytheir periphery with the walls defining the tubular means 35 and 36 and in this manner efficiently and economically rigidify the structure. By such construction, additional insert supports are not required and the support structure 31 may be made in its entirety from `a single strip or sheet of material.

The tubular means 34 is likewise provided with cut out tabs 81 which tabs in this instance are cut out from different side walls of the tube defining the tubular means 34 in such a manner that the tabs may be engaged in back-to-back relation -and adhesively secured together by means such as glue and the like at g. The tabs 81 are also adapted to nestingly engage within side walls of the tubular means 34 so as to rigidify the same.

To assist in the further rigidiiication of the tubular means 34 and to provide a tight joint between the tubular means 34 and the tubular means 35 and 36, tabs 82 are cut out of the sections 76 and 77, one tab for each section. When the tubular means 34, 35 and 36 are folded into position, the tabs 82 -are adapted to be defiected into nested interlock engagement within the tube defined by the tubular means 34. When the tabs 82 are in assembled position, they are particularly advantageous in that they maintain the section or side wall 59 in substantially perpendicular relation to the section 33.

To form the tubular support means 37 and 38 which engage between upper rearward portions of the cabinet 2k3 and the container rear end wall 13, the blank 50 may be cut along a line 83 transverse to the score lines 74 and 75 defining the opposite edges of the base section 33 with the terminal ends of the line 82 being spaced inwardly from the score lines 74 and 75. Generally at the mid point of the line 82 a cut is made between `the line 83 and one edge 84 of the blank 50.

A pair of score lines 8-5 and 86 may extend between the terminal ends of the cut 83 and the edge 84 and the portion of the blank between the score lines 85 and 86 and score lines 74 and 75 may be described as sections in the same plane as and extending outwardly from the base sections 33, the sections being designated by

reference numerals

87 and 88, respectively. Between the score lines 85 and 86 are elongated tabs 89 and 90 each of which is scored at predetermined intervals along the length thereof to divide each tab into ten

sections

91 and 92 which have varying widths, with the end sections being designated at 91a and 92a, respectively.

To form the tubular support means 37 and 38, the blank 50, and more specifically the elongated tabs 89 and 90 may be bent at the score lines so that the

sections

91 and 92 are folded in a manner as to provide tubular supports. In each case, the tubular supports are of a box-like or rectangular configuration and the end tabs 91a and 92a extend diagonally across the rectangular tube. The end sections 91a and 92a are secured by adhesives such as glue g at the corner to rigidity the cushioning support means 37 and 38. More specifically, the sections 91a and 92a are adhesively secured at the right angle junction of sections 91-91 and sections 92-92, respectively.

It will be appreciated that the tubular support means 37 and 38 so formed will offer very secure support for the upper ends of the rear portion of the cabinet 23.

According to a specific feature of the invention, the

supports

35 and 36 and the

supports

37 and 38 may provide mutual support for each other, by gluing at g or otherwise securing the outer surfaces of the

sections

91 and 92 to the facing portions of the sections 76 and 77, respectively.

In summary, each of the tubular support means 34-38 is of a rectangular or box-like configuration and is reinforced by reinforcing portions Which extend transversely of the respective tubes defined by the tubular supports.,

With the elimination of the support means 34 and possibly the support means 37 and 38, the remaining structure may provide an improved pallet construction formed from a single piece of material.

It will be appreciated from the foregoing that this invention provides an inexpensive, light weight, compact, readily manufacturable support structure for supporting an article within a container with maximum safety and efficiency.

It will thus be understood that modifications and variations may be effected without departing from the scope of the novel concepts of the present invention.
