This application claims priority under 35USC§119(e) of U.S. provisional patent application 61/363,817 filed on Jul. 13, 2010, the specification of which is hereby incorporated by reference.
TECHNICAL FIELD OF THE INVENTIONThe technical field relates to three-dimensional artificial trees formed of sheet material such as cardboard and to a kit for manufacturing same.
BACKGROUNDChristmas trees are decorated evergreen coniferous trees, real or artificial and they are a tradition associated with the celebration of Christmas. There is an on-going debate between environmentalists to determine whether real or artificial trees are more environmentally friendly.
Some think that artificial trees are more environmentally friendly because they are re-used every year and thus do not generate the waste of their real counterparts. However, artificial trees are typically made with polyvinyl chloride (or PVC, otherwise known as vinyl), a non-renewable, petroleum-derived plastic.
One downside of real Christmas trees is that, because they are farmed as agricultural products, they often require repeated applications of pesticides over their typical eight-year lifecycles. Therefore, while they are growing—and then again once they are discarded—they may contribute to pollution of local watersheds. Beyond the run-off issue, the sheer number of trees that get discarded after every Christmas Holiday can be a big waste issue for municipalities that are generally not prepared to mulch them for compost.
Furthermore, both artificial and real Christmas trees must be either stored or discarded at the end of the Christmas period.
Since there is a need to reduce the impact on the environment, there is a need for a Christmas tree that is environmentally friendly, easy to assemble and disassemble, requiring a relative small storage space, and having a relatively affordable cost.

DETAILED DESCRIPTIONReferring now to the drawings, the various parts for simulating the appearance of simulated and modular three-dimensional (3D) trees and, more particularly, of evergreen trees such as fir trees used in connection with the observance of Christmas will be described. These trees are full bodied with short trunks and are of substantially pyramidal shape. The artificial tree illustrated in the drawings for simulating this appearance includes a plurality of flat sheets of various sizes. The flat sheets are mounted in an interlocking intersecting relationship to define the simulated and modular 3D tree, as it will be described in more details below.
In the embodiment shown, the simulated and modular 3D tree 20 includes three sizes of substantially triangular flat sheets. The flat sheets include several slots for interconnection of the sheets together. In the embodiment shown, the flat sheets are characterized as being substantially triangular, even if the side edges are not straight, as it will be described in more details below. One skilled in the art will appreciate that, in an alternative embodiment (not shown), the tree can include more or less than three sizes of flat sheets.
There are two embodiments of the primary sheets 22a, 22b.
The first primary substantially triangular sheet 22a further includes two secondary slots 34a extending upwardly from the base edge 26, each slot 34a being located on a respective side of the central longitudinal axis A-A and spaced-apart therefrom. The secondary slots 34a extend substantially parallel to and spaced-apart from the central longitudinal axis A-A. In the embodiment shown, the secondary slot inner ends are spaced apart longitudinally from the primary slot inner end.
The first primary substantially triangular sheet 22a further includes two tertiary slots 36a extending downwardly from the side edges 28, each slot 36a being located on a respective side of the central longitudinal axis A-A and spaced-apart therefrom. The tertiary slots 36a extend substantially parallel to the central longitudinal axis A-A and are also spaced-apart from the secondary slots 34a. The tertiary slots 36a are located outwardly of the secondary slots 34a with respect to the central longitudinal axis A-A. As the primary slot 32a, the secondary and tertiary slots 34a, 36a extend in a direction substantially perpendicular to the base edge 26.
In the embodiment shown, the secondary slots 34a are substantially equidistantly spaced apart from the primary slot 32a and their respective tertiary slots 36a. Furthermore, in the embodiment shown, the left side of the primary sheet 22, with respect to the central longitudinal axis, is a mirror image of the right side.
The two primary sheets 22a, 22b further include two base slots 38, extending upwardly from the base edge 26, each slot 38 being located on a respective side of the central longitudinal axis A-A, between the central longitudinal axis A-A and the secondary slots 34. The base slots 38 are shorter than the primary, secondary, and tertiary slots 32, 34, 36 and are designed to engage a support base 58 (
In the embodiment shown, both secondary slots 34 are located at the same distance from the central longitudinal axis A-A, on a respective side thereof. Similarly, the tertiary slots 36 are located at the same distance from the central longitudinal axis A-A, on a respective side thereof.
The primary sheets 22a, 22b have substantially the same height and surface area. They are higher and have a larger surface area than the secondary and tertiary sheets 42, 44 (
For building a simulated and modular 3D tree 20, as shown in
As mentioned above, the primary slots 32 of the primary sheets 22 are designed to be interconnected together to interlock both primary sheets 22 in a substantially orthogonal orientation. The secondary slots 34 of the primary sheets 22 are designed to interconnect the primary sheets 22 with orthogonally disposed secondary sheets 42 while the tertiary slots 36 of the primary sheets 22 are designed to interconnect the primary sheets 22 with orthogonally disposed tertiary sheets 44, as it will be described in more details below.
The lengths of each one of the primary slots 32, the secondary slots 34, and the tertiary slots 36 substantially correspond to half the length of the primary sheet 22 at the position of the slot. Thus, since the primary sheet 22 is longer at the apex 24, the primary slots 32 are longer than the secondary tertiary slots 34, 36. Similarly, the secondary slots 34 are larger than the tertiary slots 36.
As for the primary sheets 22, there are two embodiments of the secondary sheets 42a, 42b.
The first secondary substantially triangular sheet 42a further includes two secondary slots 48a, each extending downwardly from a respective one of the side edges 28, each slot 48a being located on a respective side of the central longitudinal axis A-A and spaced-apart therefrom. The secondary slots 48a extend substantially parallel to the central longitudinal axis A-A.
The first secondary substantially triangular sheet 42a further includes two tertiary slots 50a, each extending downwardly from a respective one of the side edges 28, each slot 50a being located on a respective side of the central longitudinal axis A-A and spaced-apart therefrom. The tertiary slots 50a extend substantially parallel to the central longitudinal axis A-A and are spaced-apart from the secondary slots 48a. The tertiary slots 50a are located outwardly of the secondary slots 48a. As the primary slot 46a, the secondary and tertiary slots 48a, 50a extend downwardly in a direction substantially perpendicular to the base edge 26.
As for the primary sheets 22, in the embodiment shown, the secondary slots 48 are substantially equidistantly spaced apart from the primary slot 46 and their respective tertiary slots 50. Furthermore, the left side of the secondary sheet 42 with respect to the central longitudinal axis A-A is a mirror image of the right side.
The lengths of each one of the primary slot 46, the secondary slots 48, and the tertiary slots 50 substantially correspond to half the length of the secondary sheet 42 at the position of the slot. Thus, since the secondary sheet 42 is longer at the central longitudinal axis A-A, the primary slots 46 are longer than the secondary and tertiary slots 48, 50. Similarly, the secondary slots 48 are longer than the tertiary slots 50.
For building a simulated and modular 3D tree 20, two sheets of each secondary sheet embodiment are required. The secondary sheets 42 are disposed in a substantially perpendicular relation with the intersecting secondary sheets 42.
In the embodiment shown, the secondary slots 48 are located at the same distance from the central longitudinal axis A-A, on a respective side thereof. Similarly, the tertiary slots 50 are located at the same distance from the central longitudinal axis A-A, on a respective side thereof.
The secondary sheets 42a, 42b of both embodiments have substantially the same height and surface area. They are smaller and have a smaller surface area than the primary sheets 22. However, they are higher and have a larger surface area than the tertiary sheets 44.
As mentioned above, the primary slots 46 of the secondary sheets 42 are designed to be interconnected with the orthogonally disposed primary sheets 22. The secondary slots 48 are designed to be interconnected together to interlock orthogonally disposed secondary sheets 42. The tertiary slots 50 are designed to interconnect the secondary sheets 42 with orthogonally disposed tertiary sheets 44, as it will be described in more details below.
The tertiary substantially triangular sheet 42a includes a primary and central slot 52 extending upwardly from the base edge 26, in a direction substantially perpendicular thereto, and towards the apex 24. The primary slot 52 is aligned with the central longitudinal axis A-A of the tertiary sheet 44 and it is designed to engage with one of the primary substantially triangular sheet 22 that is orthogonally disposed as it will be described in more details below. The tertiary substantially triangular sheet 44 further includes two secondary slots 54, each extending upwardly from the base edge 26, each slot 54 being located on a respective side of the central longitudinal axis A-A and spaced-apart therefrom. The secondary slots 54 extend substantially parallel to the central longitudinal axis A-A. In the embodiment shown, both secondary slots 54 are located at the same distance from the central longitudinal axis A-A, on a respective side thereof.
The tertiary sheets 44 have substantially the same height and surface area. They are smaller and have a smaller surface area than the primary and secondary sheets 22, 42.
The lengths of each one of the primary and secondary slots 52, 54 substantially correspond to half the length of the tertiary sheet 44 at the position of the slot. Thus, the primary slot 52 is longer than the secondary slots 54.
As mentioned above, the primary slots 52 of the tertiary sheets 44 are designed to interconnect with one of the orthogonally disposed primary sheets 22. The secondary slots 54 are designed to interconnect with one of the orthogonally disposed secondary sheets 42, as it will be described in more details below.
For building a simulated and modular 3D tree 20, four tertiary sheets 44 are required. In summary, for building a simulated and modular 3D tree 20, two primary sheets 22 (one of each embodiment), four secondary sheets 42 (two of each embodiment), and four tertiary sheets 44 are required.
It is appreciated that the intersecting slots can change, i.e. the slots extending downwardly from either the side edges 28 or the apex 24 can extend upwardly from the base edge 26 and vice-versa. For instance and without being limitative, the secondary slots 34 of the primary sheets 22 can extend downwardly from the side edges 28 while the intersecting primary slots 46 of the secondary sheets 42 can extend upwardly from the base edge 26. Similarly, the tertiary slots 36 of the primary sheets 22 can extend upwardly from the base edge 26 while the intersecting primary slots 50 of the tertiary sheets 44 can extend downwardly from the apex 24. Furthermore, the tertiary slots 48 of the secondary sheets 42 can extend upwardly from the base edge 26 while the intersecting secondary slots 52 of the tertiary sheets 44 can extend downwardly from the side edges 28.

Then, the second secondary sheets 42b are interconnected with the first secondary sheets 42a in a perpendicular orientation as shown in
Then; the first primary sheet 22a is interconnected with the two of the four secondary sheets 42. The first primary sheet 22a can be in a perpendicular orientation with either the first or the second secondary sheets 42a, 42b. In the embodiment shown in
The second primary sheet 22b is then interconnected with the four secondary sheets 42 and the first primary sheet 22a. The second primary sheet 22b is in a substantially perpendicular orientation with the first primary sheet 22a and the second secondary sheets 42b and in a substantially parallel orientation with the first secondary sheets 42a, as shown in
Finally, the tertiary sheets 44 are interconnected with the primary and secondary sheets 22, 42, as shown in
As shown in
Thus, the three-dimensional simulated and modular 3D tree 20 is defined by a structural system made from a criss-cross pattern of interlocking substantially triangular sheets. In an embodiment, the sheets are made of recyclable cardboard.
Each sheet is interconnected with at least two orthogonally disposed sheets of different sizes. The first primary sheet 22a is orthogonal to and interconnected with the second primary sheet 22b, the first secondary sheets 42a, and two tertiary sheets 44. The second primary sheet 22b is thus orthogonal to and interconnected with the first primary sheet 22a, the second secondary sheets 42b, and the other two tertiary sheets 44. Thus, the first primary sheet 22a and the second secondary sheets 42b extend substantially parallel to one another and in a spaced-apart relationship. Similarly, the second primary sheet 22b and the first secondary sheets 42a extend substantially parallel to one another and in a spaced-apart relationship. Each one of the primary sheets 22 and the secondary sheets 42 extend parallel to and in a spaced-apart relationship to two tertiary sheets. Each one of the secondary sheets 42 is orthogonal to and interconnected with two tertiary sheets 44.
In the embodiment shown, each one of the engageable slots has the same length. For instance and without being limitative, the primary slots 32 of the primary sheets 22 have the same length, the secondary slots 34 of the primary sheets 32 have the same length than the primary slots 46 of the secondary sheets 42, the tertiary slots 36 of the primary sheets 22 have the same length than the primary slots 52 of the tertiary sheets 44, the secondary slots 48 of the secondary sheets 42 have the same length, and the tertiary slots 50 of the secondary sheets 42 have the same length than the secondary slots 54 of the tertiary sheets 44.
Referring now to
In the embodiment shown, for each one of the flat sheet 60, the lateral slots 66 are symmetrically provided on a respective side of the central slot 62. Furthermore, the length of the lateral slots 62 substantially corresponds to half the length of the flat sheet 60. Thus, the lateral slots 62 extending upwardly from the lower edge 67 have substantially the same length than the lateral slots 62 that extend downwardly from the upper edge 64 of the sheet 60. In the embodiment shown, the central slot 62 is shorter than the lateral slots 62.
Thus, the entire 3D tree 20, including or excluding its support base 58, 59, is made of slotted sheets interlocked in a criss-crossing pattern, like an eggcrate style structural system.
In an embodiment, the flat sheets 22, 42, 44 are made of cellulosic fibers such as cardboard or paperboard. In an embodiment, the flat sheets 22, 42, 44 are fabricated out of conventional cardboard box type material. In an embodiment, the tree parts are made of recycled cardboard or paperboard. In an embodiment, the recycled cardboard or paperboard is substantially free of virgin fibers. The fact that the simulated and modular 3D tree 20 is made from a single material and very easy to disassemble makes it perfect for recycling.
It is appreciated that the simulated and modular 3D tree 20 can be provided in various sizes and colors. For instance and without being limitative, they can be provided in sizes ranging from a few inches to 8 feet of height. They can also be provided in a Christmas card size and used as such. Furthermore, they can be provided in Kraft paper color (brown), white, with an infinite variety of patterns. Patterns can also be printed on the surface of the sheets 22, 42, 44. For instance and without being limitative, printing can include glitter/metallic silk-screening on the ornaments or the tree itself, lamination with gloss, metallic glittering paper, and the like.
The flat sheets that are interconnected have one or several slots extending downwardly from either the apex or the side edges while the flat sheets that engage have one or several slots extending upwardly from the base edge.
In the embodiment shown and described above, the primary slots, the secondary slots, and the tertiary slots are equidistantly spaced-apart. However, one skilled in the art will appreciate that in an alternative embodiment (not shown), the distance between consecutive slots can vary. For instance and without being limitative, for the primary sheet, the distance between the secondary and the tertiary slots can be shorter than the distance between the primary and the secondary slots
It is appreciated that in an alternative embodiment, the 3D tree 20 can include two sizes of flat sheets or any higher number. For instance and without being limitative, an embodiment of the 3D tree 20 can include solely primary sheets 22 and secondary sheets 42. The number of slots varies in accordance with the number of sheets that will interconnect.
The simulated and modular 3D tree 20 is made up entirely of pre-cut sheets of cardboard which are slotted to slide together forming a central structural core forming a so-called egg crate divider type criss-crossing pattern. The 3D tree 20 described above is relatively inexpensive, eco-friendly, and lightweight. It can be made out of pre-cut sheets of cardboard and assembled without the use of special tools, fasteners, adhesives or the like. As such, the 3D tree 20 can be sold as a kit and hand assembled by merely compressively snapping the individual pieces together. Because of the use of cardboard panels in combination with an internal “egg crate divider” core, the resulting tree 20 is substantially rigid and dimensionally stable.
In a first direction, the egg crate divider structure of tree 20 involves a sequential set of five vertical sheets of cardboard, one corresponding to the primary sheet 22 of
The length and width of the slots are sufficient to allow the respective sheets to interlock with each other forming the egg crate divider type core structure of the tree 20, i.e. with substantially square openings.
In an alternative embodiment, the tree or the tree kit includes lights which can be mounted to the assembled tree for lightening same and to illuminate. The lights can be mounted either inwardly or outwardly of the tree structure. If the tree includes lights, the tree parts can be made of non-flammable cardboard.
The above described tree proposes an alternative to artificial or natural conventional Christmas trees, with a nice design and various finishes and colors.
The 3D tree can be stored in a box to reduce the storage space. It can be rebuilt several times.
