A connector system facilitates the connection of a first tree trunk to a second tree trunk of an artificial tree system. The connector system can prohibit rotation of the first tree trunk relative to the second tree trunk.

A fabricated decorative tree with insertable branches system is provided that includes a tree trunk configured with at least one limb stub that is configured to receive a branch. The trunk, stub, and branch all have internal supports and an external decorative skin. The stub internal support has a proximal end fixedly attached to the trunk internal support and has a stub distal end having a receptor with a channel cut at least through the internal support distal edge. Only the distal end of the branch internal support is covered with the external skin. The uncovered proximal end of the branch internal support is a male sleeve insert having an outwardly projecting alignment protuberance sized to fit within the stub's channel. Means to further secure the stub-branch joint and methods by which one set of interchangeable branches are replaced by a second set of branches are also provided.

A reusable wreath frame assembly for supporting and retaining wreath material. The reusable wreath frame assembly includes a frame and a multi-link fastening assembly. The frame forms a wreath back and is configured to extend adjacent the wreath material. The multi-link fastening assembly extends from the frame. The multi-link fastening assembly is operative to assume a fastened mode and an unfastened mode. The multi-link fastening assembly secures the wreath material to the frame when in the fastened mode. When the multi-link fastening assembly is in the unfastened mode, the wreath material can be placed on the frame.

A combustion-resistant branch assembly for an artificial tree, the branch assembly including a first branch portion including a first rod having a main portion intermediate a first end portion and a second end portion; a first group of sub-branches attached to the first branch portion, each sub-branch of the first group of sub-branches including a member having a first end portion; and a first winding, including a combustion-resistant strand, wrapped about the first end portion of the first rod of the first branch portion and the first end portion of each sub-branch of the first group of sub-branches, thereby attaching the first group of sub-branches to the first branch portion.

An article of manufacture for providing an O.sub.2 Tree for removing CO.sub.2 gas from the atmosphere according to the present invention is disclosed.

The disclosed invertible structures rely on combinations of translational movements to effect inversion. An exemplary invertible structure includes a track operable to be slidably coupled to a connector element of a longitudinal structure. In an embodiment, the connector element may include at least two connectors at least partially disposed in a slot defined in the track, which may have a plurality of translational axes for translational movements of the connectors of the longitudinal structure that would effect the inversion of the longitudinal structure.

A dual-color light string comprising a first insulated electrical wire cord, a second insulated electrical wire, two light-emitting diode devices (LED devices) and transparent glue. The first insulated electrical wire is partially exposed to form a first soldering section. The second insulated electrical wire is partially exposed to form a second soldering section. The two LED devices are respectively electrically connected to the first soldering section and the second soldering section, and the directions of bias of the two LED devices from the first soldering section to the second soldering section are opposite to each other; The transparent glue covers the two LED devices, the first soldering section and the soldering section, extends to partially cover a first insulating layer of the first insulated electrical wire and a second insulating layer of the second insulated electrical wire.
