Abstract: A flameless candle includes: a candle body; a projection screen; a supporting portion; a moving portion; an LED; and a magnetic-field-inducing circuit. The projection screen extends upwardly from an upper surface of the candle body, has a flame shape, and has a fixed position with respect to the upper surface of the candle body. The moving portion is supported by the supporting portion and includes: a transparent lens oriented diagonally; an arm extending downwardly; and a magnet on the arm. The LED is oriented to project light upwardly and diagonally such that the projected light travels through the lens, through an aperture of the upper surface of the candle body, and onto an outer surface of the projection screen. The magnetic-field-inducing circuit includes a coil that successively attracts and repels the magnet.

Abstract: The present technology provides an extendable pillar having a lower section with a base column, and an upper section with an upper column. The base column includes a ratchet mechanism that operates with a fastener rod in the upper column. When the ratchet mechanism is in a locked position, the position of the upper section is fixed. When the ratchet mechanism is in an open position, the upper section can slide along the base column to extend or compress the length of the pillar. In certain embodiments, the upper column and the base column include friction connection mating components. The friction connection mating components cooperate to allow the upper section to slide along the base column when a sufficient force is applied to the upper section, while supporting the upper column at a fixed position when the force is removed.
