Abstract

A power transfer system to facilitate the transfer of electrical power between tree trunk sections of an artificial tree is disclosed. The power transfer system can advantageously enable neighboring tree trunk sections to be electrically connected without the need to rotationally align the tree trunk sections. Power distribution subsystems can be partially disposed within the trunk sections. The power distribution subsystems can comprise a male end, a female end, or both. The male ends can have prongs and the female ends can have channels, and the prongs and channels may be positioned outside of the trunk sections. The prongs can be inserted into the channels to electrically connect the power distribution subsystems of neighboring tree trunk sections. The prongs and channels may be configured to engage one another without the need to rotationally align the tree trunk sections.

First claim

What is claimed is:

1. An artificial tree system comprising:
a plurality of tree trunk sections, including a first tree trunk section and a second tree trunk section, each respective tree trunk section having an elongate body, a first end, and a second end, wherein the first end of the first tree trunk section can be mechanically connected to the second end of the second tree trunk section about a vertical axis to form a body of the artificial tree system;
a first power distribution subsystem disposed at least in part within the first tree trunk section, the first power distribution comprising an inner prong and an outer prong;
a second power distribution subsystem disposed at least in part within the second tree trunk section, the second power distribution comprising an inner contact ring and an outer contact ring; and
a coupling comprising:
a female component mechanically attachable to the second tree trunk section, the second power distribution subsystem being disposed at least partially within the female component; and
a male component mechanically attachable to the first tree trunk section, the first power distribution subsystem being disposed at least partially within the male component,

wherein the female component is configured to receive the male component to facilitate electrical communication between the first power distribution subsystem and the second power distribution subsystem by a contacting of (i) the inner prong to the inner contact ring and (ii) the outer prong to the outer contact ring, and
wherein the female component is further configured to receive the male component independent of the rotational alignment about the vertical axis of the male component in relation to the female component.

2. The artificial tree system of claim 1 , wherein:
the female component comprises a channel housing having an inner wall, a middle wall, and an outer wall, each wall being proximal to an upper surface of the channel housing,
wherein the inner contact ring is disposed at least partially between the inner wall and middle wall, and the outer contact ring is disposed at least partially between the middle wall and outer wall.

3. The artificial tree system of claim 2 , the female component further comprising a lower cover attachable to a bottom surface of the channel housing, the lower cover configurable to contain and shield electronic components disposed within the female component.

4. The artificial tree system of claim 2 further comprising a detachably attachable safety cover proximate the female component and configurable to be receivable by the female component when the female component is not receiving the male component.

5. The artificial tree system of claim 1 , wherein:
the inner contact ring further comprises a substantially flat circular surface and one or more tabs extending away from the flat surface, the one or more tabs configured to provide electrical connection between the flat surface and one or more wires; and
the outer contact ring further comprising a substantially flat circular surface and one or more tabs extending away from the flat surface, the one or more tabs configured to provide electrical connection between the flat surface and one or more wires.

6. The artificial tree system of claim 1 ,
the male component further comprising a prong housing, the inner prong and the outer prong being disposed at least partially within the prong housing, and the prong housing comprising:
a plurality of prong cavities, each prong cavity configurable to hold the inner prong or the outer prong in place; and
a support wall extending upward from an upper surface of the prong housing, the support wall configured to abut an outer wall of one of the plurality of tree trunk sections, the support wall configured to stabilize or align the prong housing relative to the tree trunk section.

7. The artificial tree system of claim 6 , the male component further comprising an upper cover detachably attachable to the upper surface of the prong housing and configurable to shield electronic components disposed within the male component.

8. The artificial tree system of claim 6 , the inner prong and the outer prong each comprising a smooth section and a threaded section, the threaded section of each prong disposed at least partially within the prong housing, and the smooth portion of each prong protruding from the bottom surface of the prong housing.

9. The artificial tree system of claim 6 , the prong housing further comprising a first electrical connector configured for connecting the outer prong to a first wire, and a second electrical connector configured for connecting the inner prong to a second wire, the first second wires being components of one of the plurality of power distribution subsystems.

10. The artificial tree system of claim 1 , the male component further comprising an outer wall characterized by a plurality of shapes, providing a surface for an assembler of the tree to grip when mechanically connecting the first end of the first tree trunk section to the second end of the second tree trunk section about a vertical axis to form a body of the artificial tree system.

11. The artificial tree system of claim 1 further comprising a power cord extendable from one of the plurality of tree trunk sections, the power cord being connectable to a power source for providing electricity to one or more of the plurality of power distribution subsystems.

12. The artificial tree system of claim 1 , wherein one or more of the plurality of power distribution subsystems are configured to provide electrical power to accessories on the tree.

13. The artificial tree system of claim 1 , further comprising an electrical power outlet configured to receive electrical power from one of the plurality of power distribution subsystems and further configured to provide electrical power to a pluggable accessory.

14. The artificial tree system of claim 1 ,
wherein the female component is secured to the second tree trunk section such that the female component does not rotate about the vertical axis in relation to the second tree trunk section; and
wherein the male component is secured to the first tree trunk section such that the male component does not rotate about the vertical axis in relation to the first tree trunk section.

15. The artificial tree system of claim 1 , wherein one or more of the plurality of tree trunk sections comprises an aperture for passing one or more electrical wires from an interior of the respective tree trunk section to an exterior of the respective tree trunk section.

16. An artificial tree system comprising:
a plurality of tree trunk sections, including a first tree trunk section and a second tree trunk section, each respective tree trunk section having an elongate body, a first end, and a second end, wherein the first end of the first tree trunk section includes an extended portion that can be inserted into to the second end of the second tree trunk section about a vertical axis to form a body of the artificial tree system;
a plurality of power distribution subsystems, wherein one or more of the plurality of power distribution subsystems are configured to provide electrical power to accessories on the tree,
wherein a first power distribution subsystem is disposed at least in part within the first tree trunk section and a second power distribution subsystem is disposed at least in part within the second tree trunk section,
wherein the first tree trunk section includes a first aperture configured to allow one or more wires to pass from the outside of the first tree trunk se
