Abstract

Abstract A rotary type clock ornament lamp circuit structure, which comprises a turner having a transmission shaft to turn a positive pole distribution member and a negative pole distribution member to carry a plurality of sockets and lamp bulbs to rotate. By means of a ring-shaped positive pole and negative pole conductive members to respectively contact the positive pole distribution member and the transmission shaft of the turner, the positive and negative poles of the sockets are respectively connected with a power source to turn on the lamp bulbs during rotary motion.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 223 words
A rotary type clock ornament lamp circuit strcture, comprising: a turner being a forward-acting or forward-backward type of motorized or electro-magnetic turning device, having a transmission shaft thereon; a conductive seat being a circular cylinder having a higher vertical wall portion and a lower vertical wall portion, said higher vertical wall portion and said lower vertical wall portion having each a bolt hole on its topmost edge and an unitary lug at its outer side; a positive pole conductive member being substantially a copper ring having an unitary U-shaped projection transversely projecting outward and three projecting strips transversely projecting inward; a negative pole conductive member being substantially a copper ring in size smaller than the copper ring of said positive pole conductive member and having an external projection and three internal projecting strips; a positive pole distribution member comprising a cylindrical body having a distribution board on its top and a through-hole transversely through its periphery; an insulator comprised of a cylindrical post having an expanded insulating board on its top and a through-hole transversely through its periphery; a negative pole distribution member comprising a cylindrical body having a distribution board on its top and a bolt hole transversely through its periphery; a plurality of sockets; and a plurality of lamp bulbs being respectively mounted on said sockets by means of plug-in connection.
Claim 2
Dependent Claim 223 words
A rotary type clock ornament lamp circuit strcture, comprising: a turner being a forward-acting or forward-backward type of motorized or electro-magnetic turning device, having a transmission shaft thereon; a conductive seat being a circular cylinder having a higher vertical wall portion and a lower vertical wall portion, said higher vertical wall portion and said lower vertical wall portion having each a bolt hole on its topmost edge and an unitary lug at its outer side; a positive pole conductive member being substantially a copper ring having an unitary U-shaped projection transversely projecting outward and three projecting strips transversely projecting inward; a negative pole conductive member being substantially a copper ring in size smaller than the copper ring of said positive pole conductive member and having an external projection and three internal projecting strips; a positive pole distribution member comprising a cylindrical body having a distribution board on its top and a through-hole transversely through its periphery; an insulator comprised of a cylindrical post having an expanded insulating board on its top and a through-hole transversely through its periphery; a negative pole distribution member comprising a cylindrical body having a distribution board on its top and a bolt hole transversely through its periphery; a plurality of sockets; and a plurality of lamp bulbs being respectively mounted on said sockets by means of plug-in connection.
Claim 3
Dependent Claim 57 words
A rotary type clock ornament lamp circuit structure as claimed in claim 1, including three projecting strips on said positive pole conductive member and three projecting strips on said negative pole conductive member are respectively pressing on said positive pole distribution member and said transmission shaft to form a circuit permitting said transmission shaft to rotate therein.
Claim 4
Dependent Claim 58 words
A rotary type clock ornament lamp circuit structure as claimed in claim 1, wherein said positive pole distribution member and said negative pole distribution member comprise each a cylindrical body having a distribution board thereon, said distribution board being shape designed to provide a plurality of terminals according to the quantity of said lamp bulbs and said sockets.
