The present disclosure is directed to a power connector adjunct to a structural pole whose most common use is in connection with tall standing ornamental lighting whose pole is separable to reduce height for shipping, such as a lighted Christmas tree.
Ornamental lighting on poles, such as pre-lit Christmas trees are often too tall to be shipped in a box. In order to reduce their height, it is necessary for their central structural pole to be divided into multiple sections which are later joined. In pre-lit trees (i.e. trees which have their light strings affixed at the factory), there has to be a way to connect the various light strings after assembly. In the prior art, this was most often accomplished by simple power plugs hanging from branches of the tree. The user had to dig into the tree, which was often very dense, and manually make connections.
A solution which allows the user to automatically connect sections of the tree power both physically and electrically is needed.
A method of manufacture is also disclosed.
The present disclosure in various embodiments overcomes these problems.
The disclosure encompasses many embodiments. One such embodiment is detailed below in summary fashion. Please understand that this summary does not encompass the entire disclosure but is provided to assist the reader in reviewing the entire disclosure and claims which also constitute part of the disclosure.
There is disclosed a central pole/staff which is composed of at least two parts, one of which is received partially within the other to create a contiguous pole along a central axis. The pole may be made of two segments, a first and second segment, each segment being connected to a two part joint having first and second portions respectively.
The two portions fit into each other and fit into the pole segments. The portions form an intermediary joint between pole segments.
The first portion has a central aperture on its lower end and a tubular projection (which may be noncircular) on the upper end sized to be received within the first pole segment. The second portion has an upper central projection sized to be received within the first portion aperture. The second portion also has a lower aperture sized to receive the second pole segment therein.
The first portion includes a first ledge extending generally orthogonally away from the segments and the axis. The first ledge includes a first connector part extending therefrom.
The second portion includes a second ledge extending generally orthogonally away from the segments and the axis. The second ledge includes a second connector part extending therefrom. Said first and second connector parts aligned to electrically engage when said first and second portions are engaged.
In some embodiments, the first connector part includes a first block having a plurality of terminals, and the second connector part includes a recess and terminals for receiving and electrically connecting to said block.
In some embodiments the aperture on said first portion includes a guide keyway slot and the projection on said second portion includes a keyway pin, so that the slot and pin maintain alignment of the block and recess.
In some embodiments, the aperture on the first portion includes a tapered section and wherein the projection on said second portion includes an expanded diameter section at its proximal end, said expanded diameter section and said tapered section being sized to mate with each other.
Note that the terms upper and lower are only relative and may be reversed and are not necessarily according to the force of gravity.
Many other features and combinations are disclosed and claimed.
Here is a description of subcomponents: 8 is a central axis along which several parts are aligned; 10 the system of pole and connector; 12 the connector; 14 the upper/first portion of the connector; 16 the lower/second portion of the connector; 18 the upper/first central pole segment with branches showing; 20 the lower/second central pole segment with branches showing; 22 (
The following is a description of elements shown in the figures: 33 is the gap between the collar 22 and the projection 30a (the taper in projection 30a may be taller than shown in
There is disclosed a central pole/staff which is composed of at least two parts 18, 20, one of which is received partially within the other to create, via a connector 12, a contiguous pole along a central axis 8. The pole may be made of two segments, a first 18 and second 20 segment, each segment being connected to a two part joint/connector 12 having first/upper 14 and second/lower 16 portions respectively.
The two portions fit into each other and fit into the pole segments. The portions form an intermediary joint between pole segments.
The first portion has a central aperture 35 on its lower end and a tubular projection 30 (which may be circular, noncircular, or keyed) on the upper end sized to be received within the first pole segment. The second portion 16 has an upper central projection 50 sized to be received within the first portion aperture 35. The second portion also has a lower aperture sized to receive the second pole segment therein.
The first portion 14 includes a first ledge 36 extending generally orthogonally away from the segments and the axis 8. The first ledge includes a first connector part 38 extending orthogonally therefrom.
The second portion 16 includes a second ledge 56 extending generally orthogonally away from the segments and the axis 8. The second ledge includes a second connector part 58 extending therefrom. Said first and second connector parts 38/58 aligned to electrically engage when said first and second portions are engaged. In an alternate embodiment, the electrical connectors are omitted and a separate power line is provided.
In some embodiments, the first connector part includes a first block 38, having a plurality of terminals 42 and the second connector part 58 includes a recess 70, 44 and terminals for receiving and electrically connecting to said block.
In some embodiments the aperture 66 on said first portion includes a guide keyway slot 82 and the projection 80 on said second portion includes a key pin, so that the slot and pin maintain alignment of the connecting blocks when brought together. This is an aligner which maintains the portion in rotational alignment (i.e. to prevent rotation and to minimize the torque on the electrical connectors) when said portions are brought together so that said connectors align and engage. As mentioned, the upper portion of the keyway 82 may have a funnel shaped curved leading edges on either side of the sloped opening to create a trough shaped opening 83a which allows the projection 80 to be urged along the funnel shaped curved slanted sidewalls on both sides of the slot opening 80 at the open end of the projection 30. See
In some embodiments, the aperture on the first portion includes a tapered section 30c and wherein the projection on said second portion includes an expanded diameter 52 section at its proximal end, said expanded diameter section and said tapered section being sized to mate with each other.
The description of the invention and its applications as set forth herein is illustrative and is not intended to limit the scope of the invention. Variations and modifications of the embodiments disclosed herein are possible and practical alternatives to and equivalents of the various elements of the embodiments would be understood to those of ordinary skill in the art upon study of this patent document. These and other variations and modifications of the embodiments disclosed herein may be made without departing from the scope and spirit of the invention.
