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 systems can be disposed within the trunk sections. The power distribution systems can comprise a male end, a female end, or both. The male ends can have prongs and the female ends can have voids. The prongs can be inserted into the voids to electrically connect the power distribution systems of neighboring tree trunk sections. In some embodiments, the prongs and voids are designed so that the prongs of one power distribution system can engage the voids of another power distribution system without the need to rotationally align the tree trunk sections.

First claim

What is claimed is:

1. An artificial tree system comprising:
a lower trunk section including:
a male end of the lower trunk section, the male end of the lower trunk section having:
a first male connector comprising a central prong and a first, a second, and a third channel prong, the central prong and the first, second, and third channel prongs of the first male connector configured to conduct electricity;
a substantially circular outer wall (i) comprising an interior surface and (ii) defining a substantially circular channel void having a bottom surface; and
a substantially circular male end cylinder extending above the bottom surface of the circular channel void of the male end of the lower trunk section, the male end cylinder (i) comprising an outer surface, (ii) disposed proximate the channel void's center, and (iii) defining a central void, the central void having the central prong disposed at least partially therein,
wherein the first and second channel prongs are disposed along the outer surface of the male end cylinder and the third channel prong is disposed along the inner surface of the male end cylinder;

a middle trunk section comprising:
a female end of the middle trunk section having:
a first female connector, the first female connector (i) comprising a central contact device and a first, a second, and a third channel contact device, the central contact device and the first, second, and third channel contact devices of the first female connector configured to conduct electricity;
a substantially circular outer wall (i) comprising an interior surface and (ii) defining a substantially circular channel void having a bottom surface, wherein the first, second, and third channel contact devices are disposed at least partially within the channel void and extend a uniform height above the bottom surface of the channel void; and
a substantially circular female end base extension extending above the bottom surface of the channel void, the female end base extension (i) comprising an outer surface, (ii) disposed proximate the channel void's center, and (iii) defining a central void, the central void having the central contact device disposed at least partially therein,
wherein the first female connector is configured to engage the first male connector such that the central contact device of the first female connector engages the central prong of the first male connector, the first channel contact device of the first female connector engages the first channel prong of the first male connector, the second channel contact device of the first female connector engages the second channel prong of the first male connector, and the third channel contact device of the first female connector engages the third channel prong of the first male connector; and

a male end of the middle trunk section having a second male connector, the second male connector comprising a central prong and a first and a second channel prong, the central prong and the first and second channel prongs of the of the second male connector configured to conduct electricity; and

an upper trunk section including a female end, the female end of the upper trunk section having a second female connector (i) comprising a central contact device and a first and a second channel contact device, the central contact device and the first and second channel contact devices of the second female connector configured to conduct electricity, and (ii) configured to engage the second male connector such that the central contact device of the second female connector engages the central prong of the second male connector, the first channel contact device of the second female connector engages the first channel prong of the second male connector, and the second channel contact device of the second female connector engages the second channel prong of the second male connector.

2. The artificial tree system of claim 1 , wherein the lower trunk section further comprises a first and a second light string, the middle trunk section further comprises a third, a fourth, a fifth, and a sixth light string, and the upper trunk section further comprises a seventh and an eighth light string.

3. The artificial tree system of claim 2 , wherein at least one of the first, second, third, fourth, fifth, sixth, seventh, and eighth light strings comprises a plurality of single-color LED lamps.

4. The artificial tree system of claim 2 , wherein at least one of the first, second, third, fourth, fifth, sixth, seventh, and eighth light strings comprises a plurality of RGB LED lamps.

5. The artificial tree system of claim 4 , wherein each RGB LED lamp of the plurality of RGB LED lamps comprises an embedded microcontroller unit.

6. An artificial tree system comprising:
a lower trunk section including a female end, the female end of the lower trunk section having a first female connector comprising a central contact device and a first, a second, and a third channel contact device, the central contact device and the first, second, and third channel contact devices of the first female connector configured to conduct electricity;
a middle trunk section comprising:
a male end of the middle trunk section having:
a first male connector, the first male connector comprising a central prong and a first, a second, and a third channel prong, the central prong and the first, second, and third channel prongs of the first male connector configured to conduct electricity,
a substantially circular outer wall (i) comprising an interior surface and (ii) defining a substantially circular channel void having a bottom surface; and
a substantially circular male end cylinder extending above the bottom surface of the circular channel void of the male end of the lower trunk section, the male end cylinder (i) comprising an outer surface, (ii) disposed proximate the channel void's center, and (iii) defining a central void, the central void having the central prong disposed at least partially therein,
wherein the first and second channel prongs are disposed along the outer surface of the male end cylinder and the third channel prong is disposed along the inner surface of the male end cylinder, and
wherein the first male connector is configured to engage the first female connector such that the central prong of the first male connector engages the central contact device of the first female connector, the first channel prong of the first male connector engages the first channel contact device of the first female connector, the second channel prong of the first male connector engages the second channel contact device of the first female connector, and the third channel prong of the first male connector engages the third channel contact device of the first female connector; and

a female end of the middle trunk section having:
a second female connector, the second female connector comprising a central contact device and a first and a second channel contact device, the central contact device and the first and second channel contact devices of the of the second female connector configured to conduct electricity;
