Abstract
A cardboard three-dimensional tree comprises: two primary substantially triangular sheets and four secondary substantially triangular sheets, each having an apex, a base edge opposed to the apex, and two side edges connecting the apex and the base edge. A first primary sheet has a primary slot extending downwardly from the apex and a second primary sheet has a primary slot extending upwardly from the base edge and engageable in the downwardly extending primary slot defined in the first primary sheet. Each primary sheet has two secondary slots extending upwardly from the base edge. Each secondary sheet has a primary slot extending downwardly from the apex and engageable in one of the secondary slots defined in the primary sheets. The primary and the secondary sheets are engageable in an interlocking intersecting relation at the slots and cooperating to form a self-standing generally substantially triangular three-dimensional structure generally in the form of an evergreen tree.
Description
- 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.
- The technical field relates to three-dimensional artificial trees formed of sheet material such as cardboard and to a kit for manufacturing same.
- Christmas 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.
- It is therefore an aim of the present invention to address the above mentioned issues.

- Referring 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. -
FIG. 1 shows twoprimary sheets modular 3D tree 20. Eachsheet 22 has a peripheral outline which is substantially triangular. It includes anapex 24, abase edge 26, opposed to theapex 24, and twoside edges 28 extending downwardly and connecting theapex 24 to thebase edge 26. For the primary substantiallytriangular sheets 22, theapex 24 corresponds to the summit of the simulated andmodular 3D tree 20. Theside edges 28 includeprojections 30 forming the limb effect of an evergreen tree type silhouette. One skilled in the art will appreciate that the shape of theprimary sheets side edges 28 can be free ofprojections 30 or the number of projections can differ from the embodiment shown. - There are two embodiments of the
primary sheets FIG. 1 a shows a first embodiment of the primary substantiallytriangular sheet 22 a. The first primary substantiallytriangular sheet 22 a includes a primary andcentral slot 32 a extending downwardly from theapex 24 in a direction substantially perpendicular to thebase edge 26. Theprimary slot 32 a is aligned with a central longitudinal axis A-A of theprimary sheet 22 extending through theapex 24 and it is designed to engage with the second primary substantiallytriangular sheet 22 b as it will be described in more details below. - The first primary substantially
triangular sheet 22 a further includes twosecondary slots 34 a extending upwardly from thebase edge 26, eachslot 34 a being located on a respective side of the central longitudinal axis A-A and spaced-apart therefrom. Thesecondary slots 34 a 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 22 a further includes twotertiary slots 36 a extending downwardly from theside edges 28, eachslot 36 a being located on a respective side of the central longitudinal axis A-A and spaced-apart therefrom. Thetertiary slots 36 a extend substantially parallel to the central longitudinal axis A-A and are also spaced-apart from thesecondary slots 34 a. Thetertiary slots 36 a are located outwardly of thesecondary slots 34 a with respect to the central longitudinal axis A-A. As theprimary slot 32 a, the secondary andtertiary slots base edge 26. - In the embodiment shown, the
secondary slots 34 a are substantially equidistantly spaced apart from theprimary slot 32 a and their respectivetertiary slots 36 a. Furthermore, in the embodiment shown, the left side of theprimary sheet 22, with respect to the central longitudinal axis, is a mirror image of the right side. -
FIG. 1 b shows a second embodiment of the primary substantiallytriangular sheet 22 b. As the first primary substantiallytriangular sheet 22 a, the second primary substantiallytriangular sheet 22 b includes a primary andcentral slot 32 b, twosecondary slots 34 b, and twotertiary slots 36 b. The configuration of thesecondary slots 34 b and twotertiary slots 36 b of the second primary substantiallytriangular sheet 22 b is similar to the one of the first primary substantiallytriangular sheet 22 a. However, on the opposite of the first primary substantiallytriangular sheet 22 a, the primary andcentral slot 32 b extends upwardly from thebase edge 26 towards the apex 24. The inner end of the primary andcentral slot 32 a substantially corresponds to the inner end of the primary andcentral slot 32 b for interconnection of the twoprimary sheets central slot 32 a is longer than thesecondary slots 34 b. - The two
primary sheets base slots 38, extending upwardly from thebase edge 26, eachslot 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. Thebase slots 38 are shorter than the primary, secondary, and tertiary slots 32, 34, 36 and are designed to engage a support base 58 (FIG. 9 ) of the simulated andmodular 3D tree 20, as it will be described in more details below. In the embodiment shown, bothbase slots 38 are located at the same distance from the central longitudinal axis A-A, on a respective side thereof. It is appreciated that, in alternative embodiments, thebase slots 38 can be located on other sheets, that their position can change, that the simulated andmodular 3D tree 20 can be free ofbase slots 38, and that base slots can be provided on several sheets of different sizes. - 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 tertiary sheets 42, 44 (FIGS. 2 and 3 ) as it will be described in more details below. - For building a simulated and
modular 3D tree 20, as shown inFIGS. 8 and 11 , one sheet of each primary sheet embodiment is required. - As mentioned above, the primary slots 32 of the
primary sheets 22 are designed to be interconnected together to interlock bothprimary sheets 22 in a substantially orthogonal orientation. The secondary slots 34 of theprimary sheets 22 are designed to interconnect theprimary sheets 22 with orthogonally disposedsecondary sheets 42 while the tertiary slots 36 of theprimary sheets 22 are designed to interconnect theprimary sheets 22 with orthogonally disposedtertiary 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 theprimary 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. -
FIG. 2 shows two secondary substantiallytriangular sheets modular 3D tree 20, i.e. the one located between the primary and thetertiary sheets sheet 42 has a peripheral outline which is substantially triangular. As theprimary sheets 22, each one of thesecondary sheets 42 includes an apex 24, abase edge 26, opposed to the apex 24, twoside edges 28 extending downwardly and connecting the apex 24 to thebase edge 26, and a plurality ofprojections 30 extending from the side edges 28. As for theprimary sheets 22, one skilled in the art will appreciate that the shape of thesecondary sheet 42 can differ from the embodiment shown. - As for the
primary sheets 22, there are two embodiments of thesecondary sheets FIG. 2 a shows a first embodiment of the secondary substantiallytriangular sheet 42 a. The first secondary substantiallytriangular sheet 42 a includes a primary andcentral slot 46 a extending downwardly from the apex 24 in a direction substantially perpendicular to thebase edge 26. The uppercentral slot 46 a is aligned with the central longitudinal axis A-A of the substantiallytriangular sheet 42 and is designed to interconnect with one of the primary substantiallytriangular sheets 22 as it will be described in more details below. - The first secondary substantially
triangular sheet 42 a further includes twosecondary slots 48 a, each extending downwardly from a respective one of the side edges 28, eachslot 48 a being located on a respective side of the central longitudinal axis A-A and spaced-apart therefrom. Thesecondary slots 48 a extend substantially parallel to the central longitudinal axis A-A. - The first secondary substantially
triangular sheet 42 a further includes twotertiary slots 50 a, each extending downwardly from a respective one of the side edges 28, eachslot 50 a being located on a respective side of the central longitudinal axis A-A and spaced-apart therefrom. Thetertiary slots 50 a extend substantially parallel to the central longitudinal axis A-A and are spaced-apart from thesecondary slots 48 a. Thetertiary slots 50 a are located outwardly of thesecondary slots 48 a. As theprimary slot 46 a, the secondary andtertiary slots base edge 26. -
FIG. 2 b shows a second embodiment of the secondary substantiallytriangular sheet 42 b. As the first secondary substantiallytriangular sheet 42 a, the second secondary substantiallytriangular sheet 42 b includes a primary andcentral slot 46 b, twosecondary slots 48 b, and twotertiary slots 50 b. The configuration of theprimary slot 46 b and the twotertiary slots 50 b of the second secondary substantiallytriangular sheet 42 b is similar to the one of the first secondary substantiallytriangular sheet 42 a. However, on the opposite of the first secondary substantiallytriangular sheet 42 a, thesecondary slots 48 b extend upwardly from thebase edge 26 towards the apex 24. The inner ends of thesecondary slots 48 a substantially correspond to the inner ends of thesecondary slot 48 b for interconnection of twosecondary sheets - 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 thesecondary 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 thesecondary 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. Thesecondary sheets 42 are disposed in a substantially perpendicular relation with the intersectingsecondary 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 primary sheets 22. However, they are higher and have a larger surface area than thetertiary sheets 44. - As mentioned above, the primary slots 46 of the
secondary sheets 42 are designed to be interconnected with the orthogonally disposedprimary sheets 22. The secondary slots 48 are designed to be interconnected together to interlock orthogonally disposedsecondary sheets 42. The tertiary slots 50 are designed to interconnect thesecondary sheets 42 with orthogonally disposedtertiary sheets 44, as it will be described in more details below. -
FIG. 3 shows atertiary sheet 44 defining one of the outer sheets of the simulated andmodular 3D tree 20. Eachsheet 44 has a peripheral outline which is substantially triangular. As the primary andsecondary sheets tertiary sheet 44 includes an apex 24, abase edge 26, opposed to the apex 24, twoside edges 28 extending downwardly and connected to the apex 24 to thebase edge 26, and a plurality ofprojections 30 extending from the side edges 28. On the opposite of the primary andsecondary sheets tertiary sheet 44. As for the primary andsecondary sheets tertiary sheet 44 can differ from the embodiment shown. - The tertiary substantially
triangular sheet 42 a includes a primary andcentral slot 52 extending upwardly from thebase edge 26, in a direction substantially perpendicular thereto, and towards the apex 24. Theprimary slot 52 is aligned with the central longitudinal axis A-A of thetertiary sheet 44 and it is designed to engage with one of the primary substantiallytriangular sheet 22 that is orthogonally disposed as it will be described in more details below. The tertiary substantiallytriangular sheet 44 further includes twosecondary slots 54, each extending upwardly from thebase edge 26, eachslot 54 being located on a respective side of the central longitudinal axis A-A and spaced-apart therefrom. Thesecondary slots 54 extend substantially parallel to the central longitudinal axis A-A. In the embodiment shown, bothsecondary 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 andsecondary sheets - The lengths of each one of the primary and
secondary slots tertiary sheet 44 at the position of the slot. Thus, theprimary slot 52 is longer than thesecondary slots 54. - As mentioned above, the
primary slots 52 of thetertiary sheets 44 are designed to interconnect with one of the orthogonally disposedprimary sheets 22. Thesecondary slots 54 are designed to interconnect with one of the orthogonally disposedsecondary sheets 42, as it will be described in more details below. - For building a simulated and
modular 3D tree 20, fourtertiary sheets 44 are required. In summary, for building a simulated andmodular 3D tree 20, two primary sheets 22 (one of each embodiment), four secondary sheets 42 (two of each embodiment), and fourtertiary 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 theprimary sheets 22 can extend downwardly from the side edges 28 while the intersecting primary slots 46 of thesecondary sheets 42 can extend upwardly from thebase edge 26. Similarly, the tertiary slots 36 of theprimary sheets 22 can extend upwardly from thebase edge 26 while the intersecting primary slots 50 of thetertiary sheets 44 can extend downwardly from the apex 24. Furthermore, the tertiary slots 48 of thesecondary sheets 42 can extend upwardly from thebase edge 26 while the intersectingsecondary slots 52 of thetertiary sheets 44 can extend downwardly from the side edges 28. - Referring now to
FIGS. 4 to 8 , there will be illustrated a method for assembling a simulated and modular 3D tree with the substantially triangular sheets described above. It is appreciated that the method described below is exemplary only and that variants are possible. - Turning now to
FIG. 4 , two firstsecondary sheets 42 a are first provided and disposed in a substantially parallel and spaced-apart relationship wherein theslots sheets 42 a are in register, i.e. the primary slot 46 of afirst sheet 42 a is in register with the primary slot 46 of asecond sheet 42 a, etc. - Then, the second
secondary sheets 42 b are interconnected with the firstsecondary sheets 42 a in a perpendicular orientation as shown inFIG. 5 . More particularly, thesecondary slots 48 b of the secondsecondary sheets 42 b are inserted in thesecondary slots 48 a of the firstsecondary sheets 42 a. Thus, as the firstsecondary sheets 42 a, the secondsecondary sheets 42 b are disposed in a substantially parallel and spaced-apart relationship wherein theslots sheets 42 b are in register. The firstsecondary sheets 42 a are perpendicular to the secondsecondary sheets 42 b. The inner ends of thesecondary slots 48 a abut the inner ends of thesecondary slots 48 b. - Then; the first
primary sheet 22 a is interconnected with the two of the foursecondary sheets 42. The firstprimary sheet 22 a can be in a perpendicular orientation with either the first or the secondsecondary sheets FIG. 6 , the firstprimary sheet 22 a is interconnected with the firstsecondary sheets 42 a, i.e. the firstprimary sheet 22 a is substantially perpendicular to the firstsecondary sheets 42 a and substantially parallel to and spaced-apart from the secondsecondary sheets 42 b. Thesecondary slots 34 a of theprimary sheet 22 a are inserted in theprimary slots 46 a of thesecondary sheets 42 a. The inner ends of thesecondary slots 34 a abut the inner ends of theprimary slots 46 a. The firstprimary sheet 22 a extends between the two secondsecondary sheets 42 b and is spaced-apart therefrom. - The second
primary sheet 22 b is then interconnected with the foursecondary sheets 42 and the firstprimary sheet 22 a. The secondprimary sheet 22 b is in a substantially perpendicular orientation with the firstprimary sheet 22 a and the secondsecondary sheets 42 b and in a substantially parallel orientation with the firstsecondary sheets 42 a, as shown inFIG. 7 . Theprimary slot 32 b of the secondprimary sheet 22 b is inserted in theprimary slot 32 a of the firstprimary sheet 22 a. The inner end of theprimary slot 32 a abuts the inner end of theprimary slot 32 b. Thesecondary slots 34 b of theprimary sheet 22 b are inserted in theprimary slots 46 b of thesecondary sheets 42 b. The inner ends of thesecondary slots 34 b abut the inner ends of theprimary slots 46 b. The secondprimary sheet 22 b extends between the two firstsecondary sheets 42 a and is spaced-apart therefrom. - Finally, the
tertiary sheets 44 are interconnected with the primary andsecondary sheets FIG. 8 (only three of the fourtertiary sheets 44 are shown). Each one of thetertiary sheets 44 is mounted to the simulated andmodular 3D tree 20 in a substantially parallel relationship to a respective one of thesecondary sheets 42, spaced-apart therefrom. Theprimary slots 52 of thetertiary sheets 44 are inserted in a respective one of the tertiary slots 36 of theprimary sheets 22. The inner ends of theprimary slot 52 abut the inner ends of the tertiary slots 36. Thesecondary slots 54 of thetertiary sheets 44 are inserted in a respective one of the tertiary slots 50 of thesecondary sheets 42. The inner ends of thesecondary slots 54 abut the inner ends of the tertiary slots 50. - As shown in
FIG. 8 , a three-dimensional simulated andmodular 3D tree 20 having a substantially pyramidal shape is built by interconnecting together a plurality of flat and substantiallytriangular sheets - 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 22 a is orthogonal to and interconnected with the secondprimary sheet 22 b, the firstsecondary sheets 42 a, and twotertiary sheets 44. The secondprimary sheet 22 b is thus orthogonal to and interconnected with the firstprimary sheet 22 a, the secondsecondary sheets 42 b, and the other twotertiary sheets 44. Thus, the firstprimary sheet 22 a and the secondsecondary sheets 42 b extend substantially parallel to one another and in a spaced-apart relationship. Similarly, the secondprimary sheet 22 b and the firstsecondary sheets 42 a extend substantially parallel to one another and in a spaced-apart relationship. Each one of theprimary sheets 22 and thesecondary sheets 42 extend parallel to and in a spaced-apart relationship to two tertiary sheets. Each one of thesecondary sheets 42 is orthogonal to and interconnected with twotertiary 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 thesecondary sheets 42, the tertiary slots 36 of theprimary sheets 22 have the same length than theprimary slots 52 of thetertiary sheets 44, the secondary slots 48 of thesecondary sheets 42 have the same length, and the tertiary slots 50 of thesecondary sheets 42 have the same length than thesecondary slots 54 of thetertiary sheets 44. - Referring now to
FIG. 9 , there is shown asupport base 58 to represent the trunk of thetree 20 and support thesimulated 3D tree 20 on a surface.FIGS. 9 a and 9 b show a first embodiment of a support base including four substantially rectangularflat sheets 60. Eachflat sheet 60 includes one short andcentral slot 62 extending downwardly from anupper edge 64 of thesheet 60 and twolateral slots 66, eachlateral slot 66 being located on a respective side of thesheet 60. For twoflat sheets 60, thelateral slots 66 extend downwardly from theupper edge 64 of thesheet 60 and for the other twoflat sheets 60, thelateral slots 66 extend upwardly from alower edge 67. They are spaced apart from one another and are designed to engage correspondinglateral slot 66 of an orthogonally disposedsheet 60 interconnectable therewith. When interconnected together, the inner ends of thelateral slots 66 abut one another. Thecentral slots 62 are designed to engage the base slots 38 (seeFIG. 1 ) for interconnecting and supporting thesimulated 3D tree 20 as shown inFIG. 11 . When thebase slots 38 are inserted in thecentral slots 62, thesimulated 3D tree 20 is mounted on itssupport base 58. - In the embodiment shown, for each one of the
flat sheet 60, thelateral slots 66 are symmetrically provided on a respective side of thecentral slot 62. Furthermore, the length of thelateral slots 62 substantially corresponds to half the length of theflat sheet 60. Thus, thelateral slots 62 extending upwardly from thelower edge 67 have substantially the same length than thelateral slots 62 that extend downwardly from theupper edge 64 of thesheet 60. In the embodiment shown, thecentral slot 62 is shorter than thelateral slots 62. -
FIG. 10 shows that the3D tree 20 can be provided as a kit, in an unassembled form. In an embodiment, the kit can be provided in acarrying box 80 with four ormore sheet cutouts 82. Eachcutout 82 includes parts of thetree 20 described above. The components can be cut on a computer guided plotting machine and left in their sheet. These sheets are flat packed in the carryingbox 80. A manual for assembly can also be provided in the carryingbox 80. By leaving the parts in their sheet they are protected from shock damage during transport. The user assembles thetree 20 by pushing the parts from the sheets and then slides the parts together as described above. This ensures a rigid and very strong construction without the use of any glue. In an alternative embodiment, some or all of the tree parts can be already removed and separated from the sheets and placed unattached in the carryingbox 80. One skilled in the art will appreciate that the number and shape of sheet cutouts can vary from the embodiment shown. -
FIG. 11 shows a fully assembled3D tree 20 mounted on thesupport base 58.Ornaments 74 which reproduce Christmas balls and stars are mounted to thetree sheets decorations 74 include a slot which is engaged with one of thesheets 3D tree 20 can be free ofornaments 74 or that the decorations can reproduce other elements. - Thus, the
entire 3D tree 20, including or excluding itssupport 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 flat sheets 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 thesheets - 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.

- 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 the3D tree 20 can include solelyprimary sheets 22 andsecondary 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. The3D 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, the3D 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 resultingtree 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 theprimary sheet 22 ofFIG. 1 , two corresponding to thesecondary sheets 42 ofFIG. 2 , and two corresponding to thetertiary sheets 44 ofFIG. 3 . Perpendicular to the first direction, there are five other vertical sheets of cardboard. These five sheets criss-cross with the sheets in the first direction. - 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.
