Abstract
The artificial tree is collapsible by inverting a main trunk thereof to swap positions of a first end and second end. The limbs are pivotably attached to the main trunk so that they sag under force of gravity from a deployed more horizontally extending orientation to a collapsed more vertically extending orientation when the main trunk is inverted. A base is preferably provided which has wheels and static portions in contact with the ground for supporting the tree thereon. A riser extending up from the base is configured to have an end of the main trunk rest therein. A lock is also preferably provided to hold an end of the trunk within the riser of the base. A separate treetop portion is removably attachable to ends of the trunk to complete the tree when in a deployed configuration and for storage of the treetop when the tree is not collapsed.

DESCRIPTION OF THE PREFERRED EMBODIMENT
(14) Referring to the drawings, wherein like reference numerals represent like parts throughout the various drawing figures, reference numeral 10 is directed to a collapsible artificial tree (
(15) In essence, and with particular reference to
(16) The main trunk 40 (
(17) More specifically, and with particular reference to
(18) The base 20 generally includes a ground support portion defining an underlying portion of the base 20 which can rest upon a horizontal surface. This ground support portion preferably is configured to come into contact with the ground directly and to also preferably operate in conjunction with wheels 30 which are pivotably attached to the base 20 and also in contact with the ground. With a pair of wheels in contact with the ground and with the ground support portion also in contact with the ground, the base 20 can remain in fixed position when both the ground support portion and the wheels 30 are in contact with the ground, and can be readily moved if the base 20 is tilted slightly (typically with other portions of the tree 10 supported upon the base 20) and then the entire tree 10 and base 20 can be rolled upon the wheels. The tree 10 is thus stable when erected and oriented vertically but can be tilted onto the wheels and then readily rolled from one position to another. Such movement can occur when the tree 10 is in a deployed configuration (
(19) With the preferred form of base 20, a riser 22 extends vertically up from other portions of the base 20. As an alternative, the riser 22 could be located largely below other portions of the base 20, such that it is in the form of a hole which extends down into the base 20. The riser 22 has a top 23 defining an uppermost portion thereof. A bottom 24 is provided opposite the top 23 and is typically affixed to underlying support portions of the base 20. A lock 25 is preferably provided near the top 23 of the riser 22. This lock 25, in one form, includes a knob 26 which can be grasped by a user and extended toward and away from the riser 22. A shaft 27 is coupled to the knob 26 and can be selectively positioned extending into a hollow core 29 of the riser 22 or pulled out of the hollow core 29 of the riser 22. A horizontal extension 28 is affixed to the riser 22 preferably in a substantially horizontal orientation and with a hollow interior allowing the shaft 27 to move through the horizontal extension 28 and intersect the hollow core 29.
(20) The hollow core 29 preferably extends symmetrically about a central axis of the riser 22. This central axis defines a line along which the main trunk 40 of the tree 10 is oriented when the main trunk 40 is supported upon the base 20 through the riser 22. The ends 42, 44 of the main trunk 40 are each preferably sized to fit within this hollow core 29 of the riser 22 for support of the main trunk 40 of the tree 10 in either the deployed configuration (
(21) While the riser 22 preferably has the hollow core 29 therein, it is conceivable that the riser 22 could have a solid configuration (or be open) and the ends 42, 44 of the main trunk 40 could be sized to reside over and upon an outer side of the riser 22 so that a diameter of the riser 22 would be smaller than a diameter of hollow ends 42, 44 of the main trunk 40 (or widths if the cross-section of the riser 22 and/or the ends 42, 44 is other than circular).
(22) While the hollow core 29 is preferably defined as residing within the riser 22, the base 20 could have a hole extending down thereinto which would act similarly to the hollow core 29 of the riser 22 and have a central axis along which the main trunk 40 can be oriented. Such a hole extending into the base 20 would thus function as an alternative to the riser 22 of the base 20 and still provide support for the main trunk 40 of the tree 10.
(23) In this preferred embodiment for the base 20, wheels 30 are provided rotatably attached to rigid portions of the base 20 through axles 31. The rigid portions of the base 20 include a series of elements. These elements preferably include outer arms 32 which are parallel to each other and spaced apart by a central arm 33. Two common ends of the outer arms 32 preferably each include wheel gaps 34 thereon. At the wheel gaps 34, central portions of the arms 32 have been removed sufficiently so that the wheel 30 can reside within this wheel gap 34. Axles 31 span the wheel gap 34 and support the wheels 30 in rotating fashion relative to the arms 32. Wheels 30 are sized sufficiently large and positioned upon the axles 31 at appropriate locations so that portions of the wheels 30 extend below lowermost portions of the outer arms 32. In this way, the wheels 30 are in contact with an underlying support surface, when the base 20 is in an upright orientation (see for instance
(24) Ends of the outer arms 32 opposite the wheels 30 preferably each include a pivoting foot 36. This pivoting foot 36 pivots about a pintle 37 and includes a lowermost portion in the form of a tread 38. The pivoting foot 36 is not strictly required to pivot, but can to some extend accommodate less than entirely flat surfaces more completely with such a pivoting feature. The pivoting foot 36 preferably has a somewhat triangular configuration when viewed from the side so that the tread 38 portion is relatively large to provide a fixed portion of the ground support portion of the base 20 at ends of the outer arms 32 opposite the wheels 30. If desired, locks can be provided on the wheels 30 so that the rotation of the wheels 30 can be prevented, such as when it is desired that the base 20 be particular stable. Utilization of the pivoting foot 36 also particularly resists sliding and horizontal movement of the base 20 in a horizontal direction.
(25) As an alternative to the base 20, an alternative base 120 is provided (
(26) With particular reference to
(27) With particular reference to
(28) The main trunk 40 extends from a first end 42 to a second end 44. These ends 42, 44 are preferably circular in cross-sectional form and have a size slightly smaller than a size of the hollow core 29. In this way, both the first end 42 and second end 44 can be placed within the hollow core 29 of the base 20. Preferably, when deployed (
(29) In one embodiment, the main trunk 40 includes limb support collars 45 at spaced intervals there along. These limb support collars 45 are provided adjacent where limbs 50 are pivotably attached to the base 20. Each limb 50 includes a root 51 adjacent the main trunk 40 and opposite a tip 55. An axle 52 is provided attaching the limbs 50 in a rotatable fashion to the main trunk 40. A stop 54 is provided on at least one side of where the limbs 50 attach to the main trunk 40 which stop acts to keep the limbs 50 from pivoting beyond an amount desired. The limbs 50 can be configured in a variety of different ways and be pivotably attached to the main trunk 40 in a variety of different ways. In one embodiment the limbs 50 are attached to the main trunk 40 in the manner depicted in
(30) With particular reference to
(31) Most preferably, this collapsed angle for the limbs 50 is 70 away from the deployed configuration for the limbs 50. Such rotation of the limbs 50 is depicted by arrow E (
(32) Each of the limbs 50 is preferably an elongate rigid structure with a plurality of such limbs 50 radiating from the rotating trunk 40. Most preferably, the limbs 50 extend in many different directions radially from the trunk 40 (
(33) A core 46 passing through an interior of the trunk 40 is preferably hollow. Such a hollow core 46 minimizes weight of the trunk 40 while maintaining strength for the trunk 40 and also optionally provides a pathway through which electric equipment for the lights 70 can be routed. Slots 48 (
(34) In the embodiment of
(35) Branches 60 optionally but preferably radiate from the limbs 50 in a pattern which mimics at least some natural tree or otherwise has a desirable form. Typically, needles also extend from the branches 60. These needles 62 can be actual natural needles such as pine needles, but most typically are synthetic structures such as attached by wire or adhesive to the branches 60. It is also conceivable that needles 62 can also be directly attached to the limbs 50. The branches 60 can have a generally planar form such as might exist on a noble fir, or might have a more bushy cylindrical form which might be provided on many different types of pines. Needles 62 can also be long or short depending on the design characteristics desired for the tree 10.
(36) With particular reference to
(37) As these cords pass the limbs 50, the cords are routed out the limbs 50 and terminate at various different locations with lights 70. Various different controllers can be provided and various different lights can be provided if desired so that a variety of different light displays can be provided through the lights 70. The cord 72 can be routed through an interior of the trunk 40 (and also conceivable through an interior of the limbs 50). Perhaps in a simplest form of the invention, the cord 72 can merely be wrapped around an exterior of the fixed trunk 30 and an exterior of the trunk 40. The cord 72 can be camouflaged to have a color similar to that of the fixed trunk 30, trunk 40 and limbs 50 (i.e. green) to help hide the cords 72.
(38) Most preferably the main trunk 40 and limbs 50 extending therefrom do not define the entire tree 10 above the base 20. Rather, a treetop 80 is preferably provided which is removably attachable to the second end 44 of the main trunk 40 to define an uppermost portion of the tree 10. This treetop 80 includes a top trunk 82 with limbs 84 extending therefrom laterally. These limbs 84 could be in fixed orientation relative to the trunk 82 or could pivot similar to the pivoting of the limbs 50 relative to the main trunk 40.
(39) The trunk 82 extends from an upper end 86 to a lower end 88. The lower end 88 is configured to be attachable to the second end 44 of the main trunk 40 (
(40) The treetop 80 would also typically be sufficiently light and easy to handle that it could be stored in a separate box away from the main trunk 40 and base 20. Attachment of the treetop 80 to the main trunk 40 occurs along arrow B (
(41) This disclosure is provided to reveal a preferred embodiment of the invention and a best mode for practicing the invention. Having thus described the invention in this way, it should be apparent that various different modifications can be made to the preferred embodiment without departing from the scope and spirit of this invention disclosure. When structures are identified as a means to perform a function, the identification is intended to include all structures which can perform the function specified. When structures of this invention are identified as being coupled together, such language should be interpreted broadly to include the structures being coupled directly together or coupled together through intervening structures. Such coupling could be permanent or temporary and either in a rigid fashion or in a fashion which allows pivoting, sliding or other relative motion while still providing some form of attachment, unless specifically restricted.
