Abstract
An elevation adjustable window candle includes a candlestick having axial sliding grooves axially disposed between stop portions and an inside shoulder therein, a candle shaft having springy retaining blocks equiangularly suspending in the bottom side thereof and respectively axially slidably coupled to the sliding grooves in the candlestick to secure the candle shaft to the candlestick at the desired elevation by means of friction resistance, and a lampshell mounted on the top end of the candle shaft and holding a LED lamp module therein.
Claims9
An elevation adjustable window candle, comprising:
- a candlestick comprising a receiving hole axially downwardly extending from the topmost edge thereof to a predetermined depth, a plurality of sliding grooves axially disposed in said receiving hole, a plurality of stop portions disposed in said receiving hole at a top side of each of said sliding grooves, and at least one positioning member disposed in said receiving hole at a bottom side far from the topmost edge of said candlestick;
- a candle shaft being a tubular shaft member comprising a tubular peripheral wall defining therein an axial hole, an inner thread spirally extending along an inner surface of said peripheral wall at a top side, at least one locating slot cut through said peripheral wall at a bottom side remote from said top side for axially slidably coupling to the at least one positioning member of said candlestick, and a plurality of retaining blocks formed of a part of said peripheral wall at the bottom side and respectively coupled to said sliding grooves of said candlestick to vertically adjustably secure said candle shaft to said candlestick at the desired elevation by means of friction resistance;
- and
- a lampshell threaded into the inner thread of said candle shaft and adapted for accommodating a LED lamp module comprising a circuit board and at least one LED installed in said circuit board.

An elevation adjustable window candle, comprising;
- a candlestick comprising an upper candlestick component and a lower candlestick component, said upper candlestick component comprising an axial hole cut through opposing top and bottom sides thereof, a plurality of sliding grooves axially disposed in said axial hole, a plurality of stop portions respectively disposed at a top side of each of said sliding grooves in said axial hole, a bottom mounting portion located on a bottom side thereof, and a bottom mounting hole defined in said bottom mounting portion and disposed in communication with said axial hole in a concentric manner, said bottom mounting hole having a diameter greater than said axial hole, said lower candlestick component comprising a tubular top mounting neck press-fitted into said bottom mounting hole in said bottom mounting portion of said upper candlestick component and a plurality of positioning blocks radially inwardly protruded from an inside wall of said tubular top mounting neck;
- a candle shaft being a hollow flexible shaft member comprising a tubular peripheral wall defining therein an axial hole, an inner thread spirally extending along an inner surface of said tubular peripheral wall at a to side thereof, a plurality of locating slots cut through said tubular peripheral wall at a bottom side thereof and adapted for axially slidably coupling to the positioning blocks of said lower candlestick component, and a plurality of retaining blocks formed of a part of said tubular peripheral wall at the bottom side thereof and respectively coupled to the sliding grooves of said upper candlestick component of said candlestick to vertically adjustably secure said candle shaft to said candlestick at the desired elevation by means of friction resistance;
- and
- a lamp shell threaded into the inner thread of said candle shaft and adapted for accommodating a LED lamp module comprising a circuit board and at least one LED installed in said circuit board.
