Abstract
A lamp assembly includes a base and a post extending from the base. A socket is connected to a top of the post and has an aperture. A control member and a pull switch are received in the socket and connected to each other. An electrical cable is connected to the control member via the base and the post. A bulb frame is connected to the socket and a first connection wire connected between the control member and the bulb frame. A second connection wire is connected between the pull switch and the bulb frame. A chain is connected to the pull switch and extends through the aperture of the socket. The control member is activated by touching the chain.
Description




FIELD OF THE INVENTION




The present invention relates to a lamp assembly that has a control member connected to a pull switch and a chain. The control member is activated either by pulling the chain or touch the chain.




BACKGROUND OF THE INVENTION




A conventional lamp assembly is shown in

FIGS. 1 and 2

and generally includes a base


1


with a post


11


extending therefrom and a socket


21


is connected to a top of the post


11


. An electrical cable


5


extends through the post


11


and is connected to a pull switch


3


and a bulb frame


22


respectively by two wires


51


and


52


. A connection wire


6


is connected between the bulb frame


22


and the pull switch


3


. A chain


31


is connected to the pull switch


3


and extends through an aperture


24


of the socket


21


. The bulb frame


22


has an insertion portion


221


which is inserted in the socket


21


and a flange


222


extends from the bulb frame


22


and is rested on a top edge of the socket


21


. A positioning member


23


has an inner threaded periphery


232


which is threadedly connected to an outer threaded periphery of the socket


21


so as to position the bulb frame


22


. A bulb


4


is then connected to the bulb frame


22


.




The conventional pull switch is activated by pulling the chain


31


and the interior parts of the switch are easily to be worn out due to frequent operations and the chain


31


could be broken.




SUMMARY OF THE INVENTION




The present invention relates to a lamp assembly which comprises a base with a post extending from the base and a socket is connected to a top of the post so as to be connected to a bulb frame thereto. An aperture is defined through the socket in which a control member and a pull switch are respectively received. An electrical cable is connected to the control member and a first connection wire is connected between the control member and the bulb frame. A second connection wire is connected between the pull switch and the bulb frame.




A chain is connected to the pull switch and extends through the aperture of the socket. The control member is activated by either pulling the chain or touching the chain.




The primary object of the present invention is to provide a lamp assembly wherein the bulb of the lamp assembly is controlled by a control member which can be activated by either pulling the chain or touching the chain.











The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.




BRIEF DESCRIPTION OF THE DRAWINGS





FIG. 1

is an exploded view to show a conventional lamp assembly;





FIG. 2

is a cross sectional view to show conventional lamp assembly;





FIG. 3

is a cross sectional view to show the lamp assembly of the present invention, and





FIG. 4

is a cross sectional view to show that the chain is replaced with a cord.











DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring to

FIG. 3

, the lamp assembly of the present invention comprises a base


1


and a post


11


extending from the base


1


. A socket


21


is connected to a top of the post


11


and has an aperture


24


defined through the wall of the socket


21


. An outer threaded periphery


211


is defined in an outer periphery of the socket


21


.




A control member


7


is received in the socket


21


and a pull switch


3


is connected to the control member


7


. An electrical cable


5


extends through the base


1


and is located in the socket


21


.




A bulb frame


22


has an insertion portion


221


which is inserted in the socket


21


and a flange


222


extends from the bulb frame


22


and is rested on a top edge of the socket


21


. A bulb


4


is connected to the bulb frame


22


. A positioning member


23


has an inner threaded periphery


232


which is threadedly connected to the outer threaded periphery of the socket


21


. A position flange


231


extends inward from an inner periphery of the top of the positioning member


23


so that the bulb frame


22


is positioned by the position flange


231


.




A first connection wire


8


is connected between the control member


7


and the bulb frame


22


, and a second connection wire


80


is connected between the pull switch


3


and the bulb frame


22


.




A chain


31


is connected to the pull switch


3


and extends through the aperture


24


of the socket


21


. The control member


7


is activated either by touching the chain


31


or pulling the chain


31


.




As shown in

FIG. 4

, the chain


31


can be replaced with a cord


32


which is able to perform the same function as the chain


31


.




While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.



Claims
  • 1. A lamp assembly comprising:(a) a base including a socket extending therefrom, said socket having an aperture formed therein; (b) a bulb frame coupled to said socket for receiving a bulb element; (c) a pull switch disposed in said socket and electrically connected to said bulb frame, said pull switch including at least one actuation member extending therefrom, said pull switch being operable to selectively energize said bulb frame responsive to user manipulation of said actuation member in a predetermined manner; and, (d) a control member disposed in said socket and electrically connected to said bulb frame for independently energizing said bulb frame in touch sensitive manner, said control member being electrically connected to at least a portion of said pull switch for actuation responsive to user touch of said actuation member.
