Adjustable lamp harp
View Patent ↗An adjustable harp is disclosed for use with a lamp ( 10 ) having a base ( 11 ) and a base bracket ( 20 ). The adjustable harp ( 25 ) is coupled to the base bracket ( 20 ). The harp ( 25 ) has a top member ( 26 ) and two oppositely disposed, legs ( 27 ). Each leg ( 27 ) has a top portion ( 31 ) and a bottom portion ( 32 ) telescopically mounted within the top portion ( 31 ). The harp has locking means to releasably lock the relative positions of the top and bottom portions.
1. An adjustable harp for use with a lamp having a base and a harp bracket having oppositely disposed harp mounting arms, the adjustable harp comprising,
a top member; and
two oppositely disposed legs depending from said top member which are adapted to be coupled to the harp mounting arms, each said leg having a first portion, a second portion telescopically received within said first portion, and locking means for locking the position of said first portion relative to said second portion, said locking means comprises a threaded splayed end upon said first portion and a threaded cap configured to mate with said threaded splayed end,
whereby the height of the adjustable harp may be varied by moving the first portion relative to the second portion and subsequently locking their position through the locking means, and whereby the threading of the cap upon the threaded end causes the compression of the splayed end.
2. An adjustable harp for use with a lamp having a base and a harp bracket having oppositely disposed harp mounting arms, the adjustable harp comprising,
a top member; and
two oppositely disposed legs depending from said to member which are adapted to be coupled to the harp mounting arms, each said leg having a first portion, a second portion telescopically received within said first portion, and locking means for locking the position of said first portion relative to said second portion, said locking means comprises said first portion having a threaded end, a threaded cap configured to mate with said threaded end, and resilient material positioned between said end and said cap,
whereby the height of the adjustable harp may be varied by moving the first portion relative to the second portion and subsequently locking their position through the locking means, and whereby the threading of the cap upon the end causes the resilient material to expand and frictionally contact the second portion.
3. A lamp adjustable harp comprising,
a top member extending to two oppositely disposed legs, each said leg including a first portion, a second portion telescopically received within said first portion, and locking means for locking the position of said first portion relative to said second portion along a range of positions between a telescopically retracted position and a telescopically extended position, said locking means comprises a threaded splayed end upon said first portion and a threaded cap configured to mate with said threaded splayed end,
whereby the height of the adjustable harp may be varied by telescopically moving the second portion into the first position and then locking them relative to each other, and whereby the threading of the cap upon the threaded end causes the compression of the splayed end.
4. A lamp adjustable harp comprising,
a top member extending to two oppositely disposed legs, each said leg including a first portion, a second portion telescopically received within said first portion, and locking means for locking the position of said first portion relative to said second portion along a range of positions between a telescopically retracted position and a telescopically extended position, said locking means comprises said first portion having a threaded end, a threaded cap configured to mate with said threaded end, and resilient material positioned between said end and said cap,
whereby the height of the adjustable harp may be varied by telescopically moving the second portion into the first position and then locking them relative to each other, and whereby the threading of the cap upon the threaded end causes the resilient material to expand and frictionally contact the second portion.
