Joint structure, components and processes

摘要

An independent friction joint structure including: at least one plug part having a connection to a device, the device comprising a lamp head; at least one joint part holding the at least one plug part in place, the at least one joint part having at least one holding structure; at least one side part having the ability to generate frictional rotational resistance to keep the at least one plug part in a predetermined position; at least one electrical contact between the at least one side part and the at least one holding structure of the at least one joint part; and at least one screw to fit all the components of the independent friction joint structure together.

1. A friction joint system comprising:
at least one plug part configured for connection to an electrically powered device; at least one side part providing a frictional rotational resistance against relative rotational motion of the at least one plug part; at least one electrical contact between the at least one side part and the at least one plug part; and at least one connector that connects the at least one plug part, the at least one side part and the at least one electrical contact together; wherein the at least one plug part comprises a connector rod portion configured for connection to the electrically powered device, and the connector rod portion has a longitudinal dimension and is configured to couple to the electrically powered device and allow rotational motion of the electrically powered device about an axis of the longitudinal dimension of the connector rod portion when the connector rod portion is coupled to the electrically powered device.
