FIELD OF THE INVENTION
The present invention relates to a collapsible decorative tree that is easy to assemble and disassemble.
BACKGROUND OF THE INVENTION
A traditional Christmas tree, in its basic form, has the outline of an upright cone or in some instances an upright cone which has been truncated at the top. Artificial Christmas trees often take this traditional shape. However, there is also a market for non-traditional decorative trees that can be displayed during the Christmas season to enhance the holiday spirit.
In addition to offering a pleasant aesthetic, it is important that a decorative tree be easy for consumers to assemble and disassemble for storage and easy to maintain. It is likewise important that the trees be easy to package and ship by manufacturers and distributors.
Accordingly, it is an object of the present invention to provide a decorative tree that is aesthetically pleasing as well as easy to assemble and disassemble.
SUMMARY OF THE INVENTION
A decorative tree is constructed of a base and a central support tube (pole) extending vertically from the base. The base can be any shape but is preferably circular.
In an embodiment, the decorative tree is further comprised of a plurality of hoops which extend from the base to the top of the support tube. The plurality of hoops are pivotably connected to each other and generally extend substantially from the base to the top of the central support tube. The first hoop is connected to the base at a single connection along the periphery of the base. The first hoop is also pivotably connected to the second hoop at a single connection along the periphery of both hoops where the hoops contact each other. In a preferred embodiment, the connection between the first hoop and the second hoop is approximately 180° around the periphery (for circular or oval hoops) or substantially on the opposite side of the first hoop from the connection with the base. The third hoop is pivotably connected to the second hoop substantially on the opposite side from the connection between the first and second hoops, and the fourth hoop is connected to the third hoop along the periphery of the third hoop at a point substantially above the connection for the first and second hoops. Successive hoops are pivotably connected similarly so that when the periphery of the topmost hoop is gripped approximately at an opposite side from the connection with the immediately adjacent hoop and pulled upwardly, the plurality of hoops will all be pivotably connected together at a single connection on each adjacent hoop. It is possible that successive connections will be more or less than 180°, or not substantially opposite, from the previous point in order to create other decorative appearances.
The hoops are generally planar objects that fit around the central support tube with clearance to enable movement of the hoops relative to the central support tube. For example, the hoops can be circular, triangular, square, rectangular, snowflake-shaped, shaped as an animal, or any given shape. Further, adjacent hoops can have different shapes. Successive hoops can be the same size or different sizes.
In embodiments, a connection between hoops may include a single connecting point. However, in other embodiments, the tree may include a pivotable connection between two adjacent hoops that includes two or more connecting points in proximity to one another that form as single axis of rotation. Thus, for example, when the hoops are snowflake-shaped with multiple branches arrayed around a hub, a connection may include a connecting point on each of two adjacent branches.
In an embodiment, when it is desired that the decorative tree give the appearance of a Christmas tree, for example, otherwise conventional light strings of incandescent bulbs or LEDs can be mounted to the hoops and extend from the bottom or base of the tree up to the top of the central support tube to illuminate the tree.
When the tree is used as a Christmas tree, it can include a star, angel or other decoration on the top of the central support tube. The decoration can be lighted if desired.
It is also advantageous to reinforce the decorative tree. Thus, in an embodiment, a monofilament line or other similar string-like materials are fastened to the base portion and extend to the topmost hoop. The monofilament line may be fastened to each hoop or to selected hoops. Preferably, two or more monofilament lines are used to provide stability.
The construction of the decorative tree of the present invention enables the tree to assume a compact orientation for storage.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings, and in particular to FIG. 1A thereof, a decorative tree 10 in a first embodiment of the present invention is illustrated. After complete assembly of the tree, as shown in FIG. 1A, the tree is generally designated by the reference numeral 10.
In the embodiment of FIG. 1A, the tree 10 comprises a substantially planar or flat wheel-like base 11 and a central support tube 16 (or pole) extending vertically from the base. Base 11 may be any shape but is preferably circular. In an embodiment, base 11 includes an outer rim 13, a base hub 14 at the center of base 11, and hub connector means 12 to connect outer rim 13 to base hub 14. Hub connector means 12 may be any style of connectors that provide a sturdy support for base hub 14. For example, hub connector means may comprise one or more circumferentially-spaced spokes or links 12a, 12b, 12c, 12d that radially connect outer rim 13 and base hub 14. Alternatively, each connection means 12 may be of a helical or spiral design connecting outer rim 13 and base hub 14. Moreover, while outer rim 13 is preferably generally circular, the rim may in fact be polygonal or irregular in nature. In another embodiment, the base may be made as a unitary component with accommodation for a base hub.
Central support tube 16 (or pole) is designed to be releasably attached at the bottom of the tube to base hub 14 as described below. At or near the top of central support tube 16 is a hanger 17 which can connect an uppermost hoop (see below) to the central support tube. Hanger 17 may be packaged as preconnected to the uppermost hoop and may include a wheel-like hub means which is rigid and constructed and arranged to slip over the central support tube to connect the uppermost hoop to central support tube 16. Alternately, hanger 17 may be formed at a top part of tube 16.
Central support tube 16 can be formed of a single segment or two or more segments (see FIG. 4) which are configured and dimensioned to be removably assembled in an end-to-end relationship to form a central support tube 16 of appropriate height. Alternatively, where the central support tube 16 is formed from multiple segments, the segments may slip into each other in a telescopic arrangement. Those skilled in the mechanical arts will readily appreciate how the various segments may be combined to form a single pole and how the ends of the pole may be releasably connected to base hub 14. By way of example only, a short vertical downward extension of hanger 17 fits over and receives therein an upper end of a top pole segment 16c, while the bottom end of segment 16c fits over and receives the upper end of the next lower segment 16b, etc. until the bottom end of the bottom segment 16a fits over and over and receives therein a short vertical upward extension of base hub 14.
The tree 10 is further comprised of a plurality of hoops 20 to 28 which are connected to each other and, when the tree is assembled, extend substantially from base 11 to the top of central support tube 16. (It should be understood that the hoops need not be connected only to the top of the central support tube but may be connected toward the top, which would include a connection to the top of the tree or a point below the top of the tree.) In the embodiment shown in FIG. 1A, nine connected hoops are shown as an example. However, the number of hoops included for any particular tree, according to the present invention, may vary depending on the height of the tree and the appearance to be achieved. For example, there may be only three hoops, including a first, lowermost hoop connected to base 11, a second, uppermost hoop connected toward the top of central support tube 16, and a hoop intermediate the lowermost and uppermost hoops.
As used herein, the terms “connecting point” or “connection” between hoops is used to refer to a pivotable connection. It does not refer to possible use of wrapping a monofilament to prevent the central support tube 16 from bending relative to the base 11 of an assembled decorative tree.
In the first embodiment, the first hoop 20 is pivotably connected to the base 11 at a single connecting point 30 (a “connection” may be formed by one or more connecting points) along the periphery or “edge” (which, in this case, is outer rim 13) of the base. The first hoop 20 is also pivotably connected to the second hoop 21 at a single connecting point 31 along the periphery (or “edge”) of both hoops 20, 21. In a preferred embodiment, the connecting point 31 between the first hoop 20 and the second hoop 21 may be approximately 180° around the periphery or on the opposite side of the first hoop 20 from the connecting point 30 with the base. The third hoop 22 is pivotably connected to the second hoop 21 at a connecting point 32 which is approximately 180° from the connecting point 31 between the first and second hoops 20, 21, and the fourth hoop 23 is pivotably connected to the third hoop 22 along the periphery of the third hoop 22 at a connection point 33 which is substantially above the connecting point 31 for the first and second hoops 20, 21. Successive hoops 24 to 28 are similarly pivotably connected with respective connecting points 34 to 38. Thus, when the periphery of the topmost hoop 28 is gripped approximately 180° from the connecting point 38 with the immediately adjacent hoop 27 and pulled upwardly, the plurality of hoops will all be connected together in series at a single connecting point between each adjacent hoop.
Notably, with a series of hoops connected in this manner, while a particular hoop intermediate the lowermost and uppermost hoop is connected to adjacent hoops, the hoops adjacent the intermediate hoop are not directly connected. For example, hoop 21 is connected to adjacent hoops 20 and 22. However, there is no direct connection between hoops 20 and 22.
Non-limiting examples of different styles of connectors at the connecting points between hoops are shown and described below in connection with FIGS. 6A, 6B, and 6C. The connection between the uppermost hoop and the upper hanger 17 of central support tube 16 may comprise a plastic zip tie. It is possible that successive connecting points will be somewhat more or less than 180° from the previous point in order to create other decorative appearances. For example, adjacent hoops can be connected at 120° to cause the plurality of hoops to form a tree having a somewhat spiral appearance.
When tree 10 is completely assembled, the hoops pivot about the respective connecting points so that the hoops are angled relative to one another in a pattern of alternating orientations from the base to the top of the tree. The degree of the angles between the hoops may vary based on the desired design, the number, dimensions and shapes of the hoops used and the height of the tree 10, among other things.
The pattern of alternating orientations of the hoops can be understood with reference to the perspective view of FIG. 1A. In this figure, first hoop 20 is illustrated as pivoted about connecting point 30 in an upward, clockwise direction relative to base 11 and forming an obtuse angle relative to the x-axis. In contrast, the adjacent, second hoop 21 is pivoted upward in a counterclockwise direction and forms an acute angle with the x-axis. This pattern of alternating orientations continues through the uppermost hoop of FIG. 1A.
As used herein, the term “hoop,” unless a specific shape is mentioned, refers generally to an object, such as an object formed as a loop (generally, but not necessarily, fully closed), a conventional hoop, an annulus, or a thick or thin disk, that generally takes a planar shape and fits around the central support tube with clearance to enable movement relative to the central support tube. The hoops need not be planar. In the case of a disk, a center opening is needed to allow for the requisite clearance. The shape of the object may be, for example, a geometric shape or another generally planar shape. For example, the object may be circular (as shown in FIG. 1A), oval, triangular, square, rectangular, or polygonal or may be shaped as a snowflake, a star, or an animal, or may have any other desired shape. See, e.g., FIGS. 2A, 3A, 3B, 3C, 3D, and 5. Further, adjacent hoops can have different shapes. The various hoops can alternatively be formed in different shapes and, for example, if the “hoops” are made to look like an animal, they can appear to be topiary when viewed from a distance. Other hoops may have portions extending higher or lower than the general surface of the hoop.
Successive hoops can be the same size or different sizes. In the preferred embodiment of FIG. 1A, the adjacent hoops are shown as being progressively smaller in radius from the bottom to the top of the tree 10.
The hoops are generally formed of a substantially rigid material such as a rigid metal wire, rigid plastic, Plexiglass, Lucite, or wood, to name a few, so as to maintain the desired shapes of the hoops when assembled and disassembled. The hoops may be, for example, transparent, translucent, or opaque.
When the decorative tree is used as a Christmas tree, for example, conventional light strings of incandescent bulbs or LEDs can be mounted to the hoops and extend from the bottom or base of the tree up to the top of the central support tube. Each light string contains a plurality of miniature or midget lamps and may include flashing sets or twinkle bulbs. The light strings are not illustrated in FIG. 1A so that one skilled in the art can better appreciate the underlying structure of tree 10 according to a present invention. However, the light strings are illustrated and described with reference to the embodiment shown in FIG. 5 and thereafter.
When tree 10 is used as a Christmas tree, it can include a decorative tree topper 40, such as a star, angel or other decoration on the top of the central support tube 16. This is shown in phantom in FIG. 1A. The decoration can be lighted if desired.
In order to utilize the thinnest, lightest weight materials to fabricate base 11 and the central support tube 16, it is advantageous to reinforce the decorative tree 10 utilizing one or more monofilament lines or other similar string-like materials which are fastened to the base portion 11 at 41a, 42a and extend to the hanger 17 connected to the uppermost hoop 28. Preferably, two or more monofilament lines are used to provide stability. Monofilament line is particularly advantageous because it has some degree of stretch, is somewhat translucent and is relatively strong; however, other string or rope may be used.
Two monofilament lines 41, 42 are shown in the embodiment of FIG. 1A. Each of the lines may be fastened to each hoop at respective points along the path of each line where the monofilament lines 41, 42 contacts the hoops, when the tree is completely assembled, or each of lines 41, 42 may be fastened only to a selected hoop or hoops. Referring to FIG. 1A, as but one example, monofilament line 41 is shown as being fastened at least to base 11 at point 41a, to hoop 20 at point 41b, to hoop 21 at point 41c, and to hanger 17 at point 41j. Similarly, monofilament line 42 is shown as being fastened at least to base 11 at point 42a, to hoop 20 at point 42b, to hoop 21 at point 42c, and to hanger 17 at point 42j. Each of lines 41, 42 may be attached to each of the other hoops 22 to 28. When the decorative tree 10 is completely assembled, the tension provided by the two or more monofilament lines will prevent the central support tube 16 from bending relative to the base 11. It is not necessary to use the monofilament lines when a strong base and supporting tube are used.
As noted above, the uppermost hoop may be attached to a wheel-like hub means, such as hanger 17, which is rigid and constructed and arranged to slip over the central support tube. As shown in FIG. 1A, the monofilament lines can be connected to hanger 17, which provides stability once the hub is slipped over the top of the central support tube. A stop means either in the hub or on the central support tube maintains the monofilament lines in tension.
When used outdoors or in locations where the tree 10 may be accidentally bumped into, it is preferable to fasten the base to the ground, using stakes outdoors or tape or other means, if indoors.
FIGS. 1B, 1C, and 1D are respectively side elevational, front elevational and top views of the first embodiment of the decorative tree as shown in FIG. 1A. As such, corresponding elements to those shown FIG. 1A are identically labeled.
FIG. 2A shows a second, alternate embodiment of a decorative tree 50 of the present invention after complete assembly thereof. In this second embodiment, the tree 50 has a series of connected triangular-shaped hoops 51 to 59 that, when tree 50 is assembled, extend substantially from base 11 to the top of central support tube 16. In the illustrated embodiment, the triangular hoops are shown, for example, as oriented downward at angles of declination relative to a horizontal position. Moreover, in the embodiment shown in FIG. 2A, nine triangular hoops are shown as an example. However, the number of hoops included for any particular tree, according to the present invention, may vary depending on the height of the tree and the appearance to be achieved.
As in the first embodiment, tree 50 may comprise a base 11 and a central support tube 16 extending vertically from the base 11 and designed to be releasably attached to base 11. FIG. 2A shows a substantially planar or flat wheel-like base 11 as in the first embodiment. However, one skilled in the art will understand that base 11 may be constructed in one of various alternative configurations, such as the variations described above with reference to FIG. 1A. Likewise, central support tube 16 may be constructed in one of various alternative configurations, some of which are described above.
Further referring to FIG. 2A, a first triangular hoop 51 may be pivotably connected to outer rim 13 of base 11 at a first connecting point 61 at a single vertex of triangular-shaped hoop 51. First hoop 51 is also pivotably connected to a second triangular hoop 52 at a second connecting point 62 at a periphery or “edge” of both hoops 51, 52 where the hoops 51, 52 contact or are in close proximity to each other. In a preferred embodiment, the connecting point 61 between the first hoop 51 and the second hoop 52 may be approximately on the opposite side of the first hoop 51 from the connecting point 61 with the base 11. As an example, second connecting point 62 may be substantially located at a vertex (or apex) of triangular-shaped hoop 52 and located along a side (base) of the triangle of first hoop 51 substantially opposite connecting point 61. Thus, first connecting point 61 may be located at the apex of the triangular hoop 51 and second connecting point 62 may be located at approximately the middle of the base of the hoop 51 and at the apex of hoop 52.
The hoops 52 to 59 in the second embodiment may be similarly connected. For instance, as illustrated, hoop 52 is pivotably connected along a side thereof to a vertex of adjacent hoop 53 at connecting point 63 that is approximately opposite to connecting point 62. Hoop 53 is pivotably connected along a side thereof to adjacent hoop 54 at connecting point 64 that is approximately opposite to connecting point 63. Hoop 54 is pivotably connected along a side thereof to adjacent hoop 55 at connecting point 65 that is approximately opposite to connecting point 64. Hoop 55 is pivotably connected along a side thereof to adjacent hoop 56 at connecting point 66 that is approximately opposite to connecting point 65. Hoop 56 is pivotably connected along a side thereof to adjacent hoop 57 at connecting point 67 that is approximately opposite to connecting point 66. Hoop 57 is pivotably connected along a side thereof to adjacent hoop 58 at connecting point 68 that is approximately opposite to connecting point 67. And hoop 58 is pivotably connected along a side thereof to adjacent hoop 59 at connecting point 69 that is approximately opposite to connecting point 68. Hoop 59 is connected to hanger 17 sitting atop central support tube 16 at connecting point 70 opposite to connecting point 69.
Thus, in this second embodiment, successive hoops 51 to 59 may be connected such that when the periphery of the topmost hoop 59 is gripped approximately opposite the connecting point 69 with the immediately adjacent hoop 58 and pulled upwardly, the plurality of hoops 51 to 59 will be connected together in series at a single connecting point between each adjacent hoop.
One skilled in the art will understand that, for a particular hoop in this second embodiment, the connecting points to adjacent hoops need not be on a vertex of a triangle or at the center of the base. Variations on the assembled appearance of tree 50 can be achieved by somewhat varying the positioning of the connecting points on each hoop or by connecting apices or bases together.
As with the first embodiment, one or more monofilament lines or other similar string-like materials which are fastened to the base portion 11 at 41a, 42a and extend to the hanger 17 above the topmost hoop 59. Two monofilament lines 41, 42 are shown in the embodiment of FIG. 2A. Each of the lines may be fastened to each hoop at respective points along the path of each line where the monofilament lines 41, 42 contacts the hoops when the tree is completely assembled or each of lines 41, 42 may be fastened only to a selected hoop or hoops.
While hoops 51 to 59 are illustrated as being similar in shape, adjacent hoops can have also different shapes with some being triangular and other hoops being of a different shape. Successive hoops can be the same size or different sizes. In the preferred embodiment of FIG. 2A, the adjacent hoops are shown as being progressively smaller in size from the bottom to the top of the tree 10. However, the size of adjacent hoops may be randomly arranged.
When the decorative tree 50 is used as a Christmas tree, for example, one or more conventional light strings of incandescent bulbs or LEDs can be mounted to the hoops and extend from the bottom or base of the tree up to the top of the central support tube. The light strings are not illustrated in FIG. 2A so that one skilled in the art can better appreciate the underlying structure of tree 50 according to a present invention. However, the light strings are illustrated and described with reference to the embodiment shown in FIG. 5.
When tree 50 is used as a Christmas tree, it can include a decorative tree topper 40, such as a star, angel or other decoration on the top of the central support tube 16. The decoration can be lighted if desired.
FIGS. 2B, 2C, and 2D are respectively side elevational, front elevational and top views of the second embodiment of the decorative tree as shown in FIG. 2A. As such, corresponding elements to those shown FIG. 2A are identically labeled.
Referring to FIG. 3A, in another embodiment, a decorative tree of the present invention may include one or more star-shaped hoops 80. The series of star-shaped hoops may be connected as in the first and second embodiments of FIGS. 1A and 2A such that a decorative tree comprising a series of star-shaped hoops may be constructed.
In another embodiment, shown in FIG. 3B, a decorative tree of the present invention may include one or more rectangular-shaped hoops 90. The series of rectangular-shaped hoops may be pivotably connected as in the first and second embodiments of FIGS. 1A and 2A such that a decorative tree comprising a series of rectangular-shaped hoops may be constructed.
In yet another embodiment, shown in FIG. 3C, a decorative tree of the present invention may include one or more snowflake-shaped hoops 100. The series of snowflake-shaped hoops 100 may be pivotably connected as in the first and second embodiments of FIGS. 1A and 2A such that a decorative tree comprising a series of snowflake-shaped hoops may be constructed. A decorative tree in accordance with this embodiment is shown as tree 150 and described below with reference to FIG. 5.
In the embodiment of FIG. 3C, hoop 100 comprises six branches 101 to 106 branching, in an approximately radially symmetric pattern, from a central hub 112. Central hub 112 is sized to have a sufficient diameter to provide clearance between the hub 112 and a central support tube 16 to maintain a position of each hoop relative to the central support tube and to enable the hoops 100 to move with ease up and down central support tube 16 during assembly and disassembly of the decorative tree. Each of branches 101 to 106 may include one or more pairs of approximately symmetrical, straight rods 110, 111 emanating therefrom in a pattern forming an outward-facing double arrow on each branch. However, the rods need not be substantially symmetrical. In this embodiment, it is desirable to have a hoop 100 pivotably connect to an adjacent hoop and to base 11 at a connection that has two connecting points 114, 115, one connecting point being located at or near the outer periphery or “edge”, beyond the rods, on each of two adjacent branches 101, 106. These adjacent branches 101, 106 may be considered to form one of six “sides” (labeled “side A” but not forming a part of the snowflake design) of the snowflake. Each hoop 100 that is connected to an adjacent similarly-shaped hoop may also have two connecting points 116, 117, with one of the connecting points at the outer periphery, beyond the rods, on each of two adjacent branches 103, 104 on a side “B” of the snowflake pattern opposite to side “A.” With two connecting points, adjacent snowflake-shaped hoops may rotatably pivot relative to one another along a single axis formed by a particular “side” of the hoop.
In the embodiment of FIG. 3C, monofilament lines 41, 42 may be attached to each snowflake-shaped hoop at, for example, points 118 and 119 around the inner arrow-shaped rods along branches 102 and 105. It has been found advantageous to position the monofilament lines 41, 42 in this configuration to substantially prevent entanglement of the lines during assembled or disassembly of the tree.
FIG. 3D shows a variation on the hoop shape of FIG. 3C. As in FIG. 3C, a decorative tree of the present invention may include one or more snowflake-shaped hoops 120 with six branches 121 to 126 approximately symmetrically arrayed around a center hub 132. Hub 132 is sized to have a sufficient diameter to provide clearance between the hub 132 and the central support tube 16 so that the hoops 120 may move with ease up and down central support tube 16 during assembly and disassembly of the decorative tree. However, in the embodiment of FIG. 3D, the branches of the snowflake each include one or more leaf-shaped protrusions 130, 131 rather than straight rods 110, 111.
A snowflake-shaped hoop 120 may be connected to an adjacent snowflake-shaped hoop 120 at a connection that comprises two connecting points 134, 135 on a side of the hoop toward the outer periphery (or “edge”) of branches 121, 126, beyond protrusions 130, 131. For each hoop 120 that is connected to an adjacent similarly-shaped hoop 120, there may be two additional connecting points 136, 137, one on each of adjacent branches 123, 124 that form a side of the snowflake pattern opposite to the side formed by branches with connecting points 114, 115. Alternatively, it is possible to have a pivotable connection between adjacent hoops in which the connection comprises only a single connection point on each side. In this embodiment, monofilament lines 41, 42 may be attached along branches 122, 125 at points 138, 139.
The construction of the decorative tree of the present invention enables the tree to assume a compact orientation for storage. FIG. 4 is a view of an unassembled decorative tree compactly stowed in a storage box 140 according to the present invention.
The tree, e.g., tree 10 of FIG. 1A or tree 50 of FIG. 2A, may be disassembled by disconnecting the topmost hoop from the central support tube 16 and allowing the hoops to collapse upon one another. In the preferred embodiment, in which a hanger 17 is connected to the uppermost hoop and is removably inserted at the top of central support tube 16, hanger 17 can be removed from tube 16 to release the hoops and allow them to collapse. (In an embodiment, the lowermost hoop may be disconnectable from the base.) The central support tube 16 is then removed from the base 11 and, if made from several pieces, the pieces can be slid apart. Base 11, any lighting wrapped around the hoops, and tree topper 40 may also fit within box 140.
The storage configuration is relatively compact. If hoops having similar configurations but decreasing sizes from bottom to top are utilized, when the hoops are collapsed upon themselves, the topmost hoop will fit within the next hoop, which in turn will fit within the third hoop, the third hoop within the fourth hoop, and so forth. Thus, when in the storage configuration, the height of the decorative tree is barely greater than the thickness of the bottom hoop.
Alternatively, where the hoops are not sized to fit within one another for storage, nevertheless, compact storage can be achieved because the height of the vertical stack of hoops is substantially limited to the number of hoops times the thickness of each hoop.
Compact storage configuration is particularly advantageous since decorative trees are often used only on a seasonal basis and spend most of the time being stored. Compact storage is useful. Likewise, when the product is shipped to stores or purchased by a consumer, the compact storage configuration is convenient, making such product desirable.
FIG. 5 shows a third embodiment of a tree 150 according to the present invention. In this embodiment, tree 150 is formed of a series of hoops 151 to 158 that are each snowflake-shaped as depicted in FIG. 3C. In the illustrated embodiment, hoops 151, 152 and 153 are connected to one another with the types and possible locations of connections in this embodiment that are described above with respect to FIG. 3C. One skilled in the art will understand that hoops 154 to 158 may be connected similarly to the connections of hoops 151, 152 and 153.
However, in an embodiment of the present invention, shown in FIG. 5, hoops 154 to 158 are not shown as pivotably connected with one another. Rather, in the illustrated embodiment, hoops 154 to 158 may be secured to each other only with monofilament lines 41, 42 that are tied to hoops 154 to 158 at spaced intervals. One or more of hoops 154 to 158 could also be supported by retaining clips such as those shown in FIGS. 7A and 7B, and a retaining clip could be used to support one or more of hoops 151, 152 and 153.
In FIG. 5, the hoops of tree 140 are shown wrapped in light strings 160 starting at base 12 and upward through hoop 158 and optional tree topper 40. When illuminated with light strings 160 at night, the decorative tree 150 may give the appearance of a Christmas tree. Although only depicted with the tree of FIG. 5, one skilled in the art will understand that light strings may likewise be used in any embodiment of the present invention.
FIGS. 6A, 6B, and 6C respectively illustrate three different types of connectors that may be used at connecting points of the decorative tree of the present invention. As explained above, connecting points may be located at a connection between hoops, at a connection between the lowermost hoop and the tree base, and at a connection between the uppermost hoop and the top of the tree. The embodiments shown in these figures are provided as examples. However, other types of connectors may alternatively be used.
In FIG. 6A, the illustrated connecting point 170 comprises a first hoop 172 with a looped link 173 molded to hoop 172. The adjacent hoop, base or hub 174 has a pin 175 that fits within link 173 and limits the movement of hoop 172 relative to the adjacent hoop, base or hub 174. A light string 160 that is wrapped around decorative tree includes bulbs 177 in respective sockets 178.
In FIG. 6B, the illustrated connecting point 180 comprises a ring 181 formed on hoop 182, a ring 183 formed on adjacent base 12 (or on hanger 17) and a removable clip 184 that connects rings 181 and 183. FIG. 6B also illustrates light strings 160 wrapped around hoop 182.
FIG. 6C depicts another embodiment of a connecting point 190. In this embodiment, a loop 191 at connecting point 114 on one branch of a snowflake-shaped hoop 100 interlocks with another loop 192 at connecting point 116 of a branch of an adjacent, snowflake-shaped hoop.
To further maintain the stability of the decorative tree according to the present invention, it may be advantageous to use a retaining clip under one or more of the hoops of the tree. This optional feature is illustrated in FIG. 7A. In FIG. 7A, a hoop 200 can be positioned above a minimum desired vertically-assembled position with the assistance of a removable retaining clip 210. In this embodiment, central support tube 16 of the decorative tree includes a pair of substantially horizontal positioning holes 212, 214 at a particular height. During assembly, after the series of hoops is extended from the base to the top hanger along central support tube 16, a removable clip 210 may be inserted through holes 212, 214 to maintain hoop 200 above the desired height. Clips 210 may be used for each hoop or just at one or more of the hoops of the tree. FIG. 7B shows an isometric view of the hoop 200 of FIG. 7A with the inserted retaining pin 210. During disassembly of the tree, the clip 210 must be removed.
Now that embodiments of the present invention have been shown and described in detail, various modifications and improvements thereon can become readily apparent to those skilled in the art. Accordingly, the exemplary embodiments of the present invention, as set forth above, are intended to be illustrative, not limiting. The spirit and scope of the present invention is to be construed broadly.
