Description




FIELD OF THE INVENTION




The present invention is directed to a packing material apparatus for isolating and protecting an item, and is particularly directed to an apparatus which is lightweight, recyclable, easily assembled and easily broken down to a flat condition.




BACKGROUND OF THE INVENTION




In the packaging and transport of delicate items such as electronic equipment, various techniques are used to isolate the item from damage. Such damage often occurs during shipping and is beyond control of the manufacturer. Damage occurs due to shock, vibration, crushing of a shipping container, and/or intrusion through an exterior of the shipping container. The prior art has utilized such devices such as foamed elastomers/plastics and laminated paper/wood products to support the corners of the products. The synthetic products are difficult to recycle and generate static charges which can damage sensitive electronic items. The laminated products are heavy for their size and difficult to configure to adequately isolate the product from both shock and vibration.




SUMMARY OF THE INVENTION




The present invention provides an apparatus for protecting an article. The apparatus includes a single sheet of material folded to define a saddle portion recessed between two extending portions. The protected article is extendable into the saddle area. The two extending portions of the apparatus are defined by planar portions forming a triangular area when viewed from the side. The saddle area is defined by two triangular elements when viewed from the side and which are defined by planar portions.

DESCRIPTION OF PREFERRED EMBODIMENTS




An apparatus


10


in accordance with the present invention is illustrated in FIG.


1


. The apparatus


10


is for protecting a shipped article against damage, such as from shock, vibration, crushing, etc. The apparatus


10


is comprised of a single sheet of material. Preferably, the material is a corrugated cardboard material which is readily recyclable.




Upon viewing the apparatus


10


, three sets of triangular elements are visible. The first set has a singular triangular element


12


(FIGS.


1


-


3


), which has an apex


14


located at a relatively large distance from a base


16


. The second set has a second triangular element


18


(

FIGS. 2 and 3

) is similar to the first triangular element


12


, in that its apex


20


is located at the same distance from the base


16


. The second triangular element is located on the opposite side (see

FIGS. 2 and 3

) of the apparatus


10


from the first triangular element


12


. Located in between the first and second triangular elements


12


and


18


is the third set, which comprises two smaller/shorter triangular elements


22


and


24


. The triangular elements


22


and


24


each have their respective apex


26


and


28


located at a distance from the base


16


which is less than the distance to the apexes


14


and


20


of the triangular elements


12


and


18


.




As shown in

FIG. 3

, the two large triangular elements


12


and


18


“bracket” the shorter triangular elements


22


,


24


(triangular element


26


is hidden in FIG.


3


). The triangular elements


12


,


18


,


22


and


24


form a saddle area


30


into which an item can extend.




All of the triangular elements


12


,


18


,


22


, and


24


are formed by segments of a unitary piece of material (e.g., the corrugated cardboard material). A first side


32


of the triangular element


12


, a first side


34


of the triangular element


18


, and a first side


36


of the triangular element


22


are coplanar and are all comprised of the same continuous segment of the material. This segment of the composite material forms a general C-shape, as viewed in

FIG. 2. A

second side


38


of the triangular element


12


, a second side


40


of the triangular element


18


, and a second side


42


of the triangular element


24


are coplanar and are all formed from the same planar segment of the material. This segment of the material forms a general backwards shaped C as shown in FIG.


2


.




A second side


44


, of the triangular element


22


is formed of its own segment of material which extends at a right angle (see

FIG. 1

) from the segment of material forming the sides


32


,


34


, and


36


. The first side


46


(

FIG. 2

) of the triangular element


24


is formed of its own segment of material. The side


46


extends at a right angle (see

FIG. 1

) to the segment of material which form s the sides


38


,


40


, and


42


.




The sides


44


and


46


are joined at a fold seam line


48


. The fold seam line


48


is located “below” (a s viewed in

FIG. 1

) the apexes


14


and


20


of the triangular elements


12


and


18


. The side


44


is joined to the side


36


at the apex


26


which also forms its own fold line. The side


46


is joined to the side


42


of the triangular element


24


at its apex


28


, and which also forms its own fold line.




The base


16


includes two, optional tabs


50


and


52


. The tab


50


is attached to a “lower” (as viewed in

FIG. 1

) edge of side


36


of the triangular element


22


at a fold line


54


. The tab


52


is attached to a “lower” (as viewed in

FIG. 1

) edge of the side


42


of the triangular element


24


at a fold line


56


.




The triangular elements


12


,


18


,


22


, and


24


, the saddle area


30


, etc. of the apparatus


10


may more easily be viewed in the perspective view of FIG.


4


. The perspective view of

FIG. 4

is taken from a vantage point which is to the right and up from the viewpoint which one would have for FIG.


2


. Also as seen best in

FIG. 4

, the base


16


has a seam


60


and a formed notch


62


. The notch is sized such that the “lower” ends of the sides


44


and


46


(i.e., at fold line


48


) of the triangular elements


22


and


24


fit into the slot


62


. The seam


60


is comprised of tab elements


64


and


66


, which abut “below” the apex


20


of the triangular element


18


and tab elements


68


and


70


which abut “below” the apex


14


of the triangular element


12


. The junction of the tab elements


64


,


66


, and


68


,


70


are held in place via adhesive tape strips


72


and


74


which are shown in

FIG. 4

as being disjoint from the apparatus for illustrative purposes only.




To now illustrate how an item


80


which is to be secured fits and is held by the apparatus


10


, attention is directed to FIG.


5


. In

FIG. 5

, a portion of the item


80


extends into the saddle area


30


of the apparatus


10


. One side


82


of the item


80


abuts against the apexes


26


and


28


of the triangular elements


22


and


24


, respectively. Also, the “upper” portion of the triangular element


18


is located on one side of the item


80


and the “upper” portion of the triangular element


12


(not visible in

FIG. 5

) is located on the opposite side of the item


80


.




Turning now to

FIG. 6

, an assembly process for the apparatus


10


will be appreciated. As shown in

FIG. 6

, the apparatus


10


starts out as a single, continuous piece of flat sheet material, i.e., corrugated cardboard. The single sheet of material has a length and a width. During the folding procedure, the width is not changed. However, the length of the finished apparatus is much less than its length in the unfolded condition. The sheet of material is prepared by cutting out a notch


62


A to leave the tabs


64


and


68


on the one base section


16


A (see the left-hand side of FIG.


6


). Similarly, a notch


62


B is cut out to leave the tabs


66


and


70


at the other base portion


16


B (see the right-hand side of FIG.


6


). It will be recalled that in the finished apparatus


10


, the notch portions


62


A and


62


B will conjoin to form the slot


62


, when tab


64


engages tab


66


and tab


68


engages tab


70


.




Next, the tab


50


is cut from the base portion


16


A. Specifically, two parallel cuts


92


and


94


are made in the lengthwise direction from the fold line


54


. The cuts


92


and


94


extend from the fold line to a location spaced away from the notch


62


A. A third cut


96


extends between the ends of the cuts


92


and


94


. Accordingly, the tab


50


is a flap connected to the rest of the sheet material at the fold line


54


. Further, the tab


50


is the portion of the material which initially was the center portion of the base portion


16


A.




Similarly, the tab


52


is cut from the base portion


16


B. Two parallel cuts


98


and


100


extend in the lengthwise direction from the fold line


56


toward the notch


62


. The cuts


98


and


100


extend to a distance spaced away from the notch


62


B. A cut


102


extends between the end of the cuts


98


and


100


. Accordingly, the tab


52


is connected to the rest of the sheet material at the fold line


56


and is separable from the base portion


16


B.




It will be appreciated that in the flat condition, the apexes


14


,


20


,


26


, and


28


are foldlines. In order to form the triangular elements


22


and


24


, two cuts


104


and


106


are made into the sheet material. Specifically, the cuts


104


and


106


extend in the lengthwise direction across the line connecting the foldlines (in the flat condition)


14


,


48


, and


20


. The cut


104


extends from the center of the flat material (i.e., at foldline


20


), to a location which is one-half the length of the side


34


. The terminus of the cut


104


on the left side is at the foldline


26


. The cut


104


similarly extends to the right, as viewed in

FIG. 6

, halfway along the side


40


and terminates at the foldline


28


.




The cut


106


extends parallel to the cut


104


. The cut


106


extends across the center fold area (i.e., folds


14


,


48


, and


20


) and terminates at the foldline


26


and also terminates at the foldline


28


. With the cuts


104


and


106


, the sides


48


and


46


(which form part of the triangular elements


22


and


24


) are separable from the sides


34


and


40


of the triangular portion


18


, and are also separable from the sides


32


and


38


which form the triangular portion


12


.




To begin the folding process (see FIG.


7


), the base portion


16


A is folded (upward, as viewed in

FIG. 7

) away from the tab


50


. Similarly, the base portion


16


B is folded (upward as viewed in

FIG. 7

) away from the tab


52


. The foldline


48


and the foldlines


14


and


20


(foldline


14


not visible in

FIG. 7

) are simultaneously folded and moved away from each other. Specifically, foldline


48


is moved in the same direction as the base portions


16


A and


16


B (upward as viewed in FIG.


7


). Foldlines


20


and


14


are moved downward as viewed in FIG.


7


. Simultaneously with the folding of foldlines


14


,


48


, and


20


, folds occur at foldlines


26


and


28


.




The foldlines


48


and


14


/


20


are moved away from each other until the foldlines


14


/


20


form the apex of a right angle (i.e., sides


34


and


40


are perpendicular, and sides


32


and


38


are perpendicular). At this same time, the foldline


48


forms an apex of a right angle (i.e., sides


44


and


46


are perpendicular). Further, at this time, foldlines


26


and


28


form apexes of respective right angles. For foldline


26


, the sides


36


and


44


of the triangular portion


22


are perpendicular. For the foldline


28


, the sides


42


and


46


of the triangular portion


24


are perpendicular to each other.




Next, as viewed in

FIG. 8

, the base portion


16


A is further folded toward the foldline


48


. Also, the base portion


16


B is also folded toward the foldline


48


. The base portions


16


A and


16


B are moved to engage the foldline


48


in their respective notches


62


A and


62


B, which know form the slot


62


. The base portion


16


A forms an arcuate angle A with the side


34


of the triangular portion


18


as shown in FIG.


8


. Similarly, the base portion


16


B forms an arcuate angle B with the side


40


. The base portions


16


A and


16


B now form the base


16


with the tab


64


abutting the tab


66


and the tab


68


abutting the tab


70


(tabs


68


and


70


not shown in FIG.


8


). The base portions


16


A and


16


B are now generally perpendicular to the tabs


50


and


52


. To complete the assembly procedure, the adhesive tape strip


72


is applied across the tabs


68


and


70


(not shown in FIG.


8


). The adhesive tape strip


74


is applied across the tabs


64


and


66


. The apparatus


10


is now rigid and cannot be unfolded until the strips of adhesive tape


72


and


74


are removed.




In order to package the item


80


(which is illustrated in

FIGS. 9 and 10

as an electronic equipment box), the item


80


is “surrounded” by a number of the apparatus


10


of the present invention. The example packing shown in

FIGS. 9 and 10

utilizes four of the apparatus


10


. The several apparatus are labeled


10


A-


10


D. The item


80


and each of the apparatus


10


A-


10


D are matched in size such that the item


80


fits snugly into the saddle


30


. The several apparatus


10


A-


10


D are “secured” to the item


80


by pushing (indicated by push arrows) the respective apparatus onto the item


80


such that the item


80


extends into the respective saddle


30


.




With the several apparatus


10


A-


10


D located on the item


80


, the assembly of the item


80


with its several packing apparatus


10


A-


10


D properly located, can be located within a shipping box or container (not shown in FIGS.


9


and


10


).




A second embodiment in accordance with the present invention is illustrated in FIG.


11


. The apparatus


200


of the second embodiment has certain similarities to the first embodiment described above. Specifically, the apparatus


200


has triangular elements which form saddles. The apparatus


200


of the second embodiment differs from the first embodiment in than the second embodiment has two groups of triangles, each group forming its own saddle.




Specifically, as shown in

FIG. 12

, the apparatus


200


includes large triangular portions


212


and


218


. The triangular portion


212


includes side portions


232


and


238


which meet at an apex


214


. The triangular portion


218


includes wall sections


234


and


240


which meet at an apex


220


. The triangular portions


212


and


218


“bracket” triangular portions


222


and


224


. The triangular element


222


includes wall portions


236


and


244


. The triangular section


224


includes wall portions


246


and


242


.




The wall sections


232


,


234


, and


236


are continuous, are coplanar, and form a general C-shape. Similarly, the wall sections


238


,


240


, and


242


are also continuous and coplanar, and form a general backward C-shape. The wall section


244


extends perpendicular to the wall sections


232


,


234


, and


236


. Similarly, the wall section


224


extends perpendicular to the wall sections


238


,


240


, and


242


. The wall sections


244


and


246


are joined to be perpendicular at a fold


248


. The wall section


222


is connected to the wall section


236


at fold


226


which forms the apex of the triangular portion


222


. The wall section


242


is connected to the wall section


246


by the fold


228


which forms the apex of the triangular element


224


. The fold


248


is located “below” the apex


214


and


220


of the large triangular portions


212


and


218


, as viewed in FIG.


11


.




The second group of triangular elements has similar segments which are identified with identical numbers, but which include a prime. The two triangular sections are connected at a foldline


255


. Specifically, the wall portions


238


,


240


, and


242


of the first group of triangular elements (left-hand group as viewed in

FIG. 11

) is connected to the wall section


232


′,


234


′, and


236


′ of the second set of triangular elements. Each group of triangular elements forms a saddle. The saddle


230


′ is illustrated in

FIG. 13

for the second set of triangular elements.




Extending under both sets of triangular elements is a base


216


. The base


216


is connected on the lefthand side, as viewed in

FIG. 11

, at a foldline


254


. The base


216


is connected on the righthand side by a foldline


256


. The base


216


is comprised of base elements


216


A and


216


B which are connected via strips of adhesive tape


272


and


274


beneath the foldline


255


, as will be explained in further detail below.




Similar to the first embodiment, the second embodiment is made from a single, flat sheet of material. Preferably, the material is corrugated cardboard.

FIG. 14

shows such a piece of material in a prefolded condition.

FIG. 14

also illustrates certain other structural elements of the device. Specifically, two notches


262


A and


260


B are illustrated. These notches conjoin to form a slot


262


as will be described later. A slot


320


is cut in the base portion


216


A such that its major axis extends along the widthwise direction. Similarly, a slot


324


is cut in the base portion


216


B. A notch cut


326


is cut to create a tab


328


, at and adjacent to, the foldline


255


.




Further, similar to the first embodiment, cuts


304


and


306


are provided in a direction perpendicular to the lengthwise extent of the sheet to define the wall portions


244


and


246


. The cuts


304


and


306


extend perpendicularly across the foldline area of


214


,


248


,


220


and terminate at the foldlines of


226


and


228


. Similarly, at the portion designated with prime numerals, cuts


304


′ and


306


′ extend across the foldline area of


214


′,


248


′, and


220


′, and terminate at the foldlines


226


′ and


228


′.




In order to begin the folding process of the second embodiment, folds are initiated as shown in FIG.


15


. Specifically, the foldlines


248


and


220


/


214


are moved away from each other and simultaneously folded. This folding action also causes the folds


226


and


228


to appear. The base portion


216


A is folded at the foldline


254


to move the tabs


264


and


268


(tab


268


not visible in

FIG. 15

) toward the foldline


255


. Similarly on the righthand side (as viewed in FIG.


15


), folds


214


′,


220


′,


248


′,


226


′,


228


′, and


256


′ are created. Also, the tab


328


is punched out from its cut


326


. The material is folded at the foldline


256


such that the portions of the material


238


,


240


,


242


face the portions of material


232


′,


234


′, and


236


′ (i.e., the apexes


214


,


214


′,


220


,


220


′ point in the same direction). In order to complete the folding, the tab


264


is brought into abutment with the tab


266


, and the tab


266


is brought into abutment with the tab


270


. The tab


328


extends through the slot


262


(defined by the notch portions


262


A and


262


B). The portion at the fold


248


extends into the slot


320


and the portion at fold


248


′ extends into the slot


324


. To complete the assembly, the strips of adhesive tape


272


and


274


are applied to extend across the respective tabs


264


,


266


,


268


, and


270


.




Similar to the first embodiment, the second embodiment is used to secure and protect a delicate item. The item is located to extend within the saddles


230


and


230
