Abstract
An adjustable lighting fixture having a power transfer means, such as a gearbox, interposed between the lamp holder, such as a gimbal ring, and the point of mounting, the output shaft of the gear box connected directly to the lamp holder to rotate the same about a first axis upon rotation of the input shaft of the gearbox, and the housing of the gear box being connected to the point of mounting to rotate the same about a second axis upon rotation of the housing, thereby providing for rotation of the lamp holder so mounted about two different axis from a remote location.
Claims55
A lighting system including, in combination:
- (a) a power transfer means having a single axis of power input and two axes of power output, one of said two axes of power output being coaxial with said single axis of power input, and
- (b) a light source connected to said power transfer means for rotation about each of said two axes of power output in response to a rotation of a power input means about said single axis of said power input.
In an adjustable lighting system:
- (a) a power transfer means having power input means arranged about a first axis of rotation, and power output means arranged along said first axis of rotation and a second axis of rotation, and
- (b) a light source connected to said power transfer means to rotate about said first and said second axes of rotation in response to rotational power input to said power transfer means about said first axis of rotation only.
An adjustable lighting system including, in combination:
- (a) a power transfer means having a rotational power input about a vertical axis of rotation, and
- (b) a light source connected to said power transfer means for rotation about said vertical axis of rotation and an intersecting horizontal axis of rotation in response to said rotational power input to said power transfer means about said vertical axis of rotation only.
An adjustable lighting system including, in combination:
- a) a fixture mounting pole,
- b) a single power transfer means having input means and output means, at least a portion of said power transfer means being connected to said fixture mounting pole, and;
- c) a light source connected to said output means of said power transfer means to rotate about a first axis in response to the physical rotation of said power transfer means about said first axis, and about a second axis in response to rotation of said input means about said first axis.
An adjustable lighting system including, in combination:
- (a) a track head mountable to a lighting track,
- (b) a fixture mounting pole connected to said track head,
- (c) a power transfer means including a housing, an input shaft and an output shaft, each of said input shaft and said output shaft having an axis, said housing connected to a lower end of said fixture mounting pole, said output shaft rotatable about said output shaft axis in response to rotation of said input shaft, and said fixture mounting pole rotatable in response to rotation of said housing, and
- (d) a lamp holder connected to said output shaft of said power transfer means to rotate about said input shaft axis in response to the rotation of said housing, and about said output shaft axis in response to the rotation of said input shaft, said lamp holder capable of holding a lamp which is electrically connected to said track.
An adjustable lighting system including, in combination:
- (a) a track head mountable to a lighting track,
- (b) a fixture mounting pole fixedly mounted to said track head,
- (c) a power transfer means including a housing rotatably mounted to said fixture pole, an input shaft and an output shaft, each of said input shaft and said output shaft having an axis, said housing mounted to a lower end of said fixture mounting pole, said output shaft rotatable about said output shaft axis in response to rotation of said input shaft, and said housing rotatable about said input shaft axis in reponse to the application of a rotational force thereto, and
- (d) a light source connected to said output shaft of said power transfer means to rotate about said output shaft axis in response to the rotation of said input shaft, and about said input shaft axis in response to the rotation of said housing.
A method of converting a conventional track light of a type having a track head mountable to a lighting track, and a fixture mounting pole connected at its upper end to said track head, and at its lower end to a lighting fixture having a lamp holder, to a track light wherein said lamp holder can be rotated about two intersecting axis from a remote location, said method including the steps of:
- a) disconnnecting said lighting fixture from said fixture mounting pole,
- b) attaching a power transfer means to the lower end of said fixture mounting pole of a type having an output shaft rotatable in response to rotation of an input shaft and a housing fixedly connected to said fixture mounting pole,
- c) attaching a shaft receiving means to said lighting fixture to receive said output shaft of said power transfer means,
- d) connecting said output shaft to said shaft receiving means, and
- e) providing an adjustment means connectable to said input shaft of said power transfer means to rotate the same, and thereby rotate said lighting fixture about a first axis when desired, and to said housing of said power transfer means to rotate said fixture pole when desired, thereby rotating said lighting fixture about a second axis when desired.
A method of converting a conventional track light of a type having a track head mountable to a lighting track, and a fixture mounting pole connected at its upper end to said track head, and at its lower end to a lighting fixture, to a track light wherein said lighting fixture can be rotated about two intersecting axis from a remote location, said method including the steps of:
- a) disconnecting said lighting fixture from said fixture mounting pole,
- b) replacing said fixture mounting pole with a new fixture mounting pole of a type having a power transfer means on a lower end of said fixture mounting pole of a type having an output shaft rotatable in response to rotation of an input shaft and its housing connected to said fixture mounting pole,
- c) attaching a shaft receiving means to said lighting fixture to receive said output shaft of said power transfer means,
- d) connecting said output shaft to said shaft receiving means, and
- e) providing an adjustment means connectable to said input shaft of said power transfer means to rotate the same, and thereby rotate said lighting fixture about a first axis when desired, and to said housing of said power transfer means to rotate said fixture pole when desired, thereby rotating said lighting fixture about a second axis when desired.
A method of converting a conventional track light of a type having a track head mountable to a lighting track, and a fixture mounting pole connected at its upper end to said track head, and at its lower end to a lighting fixture, to a track light wherein said lighting fixture can be rotated about two intersecting axis from a remote location, said method including the steps of:
- a) disconnecting said lighting fixture from said fixture mounting pole,
- b) providing at a point of connection between said lighting fixture and said fixture mounting pole a power transfer means of a type having an output shaft rotatable in response to a rotation of an input shaft and having a housing connected to said fixture mounting pole,
- c) attaching a shaft receiving means to said lighting fixture to receive said output shaft of said power transfer means,
- d) connecting said output shaft to said shaft receiving means, and
- e) providing an adjustment means connectable to said input shaft of said power transfer means to rotate the same, and thereby rotate said lighting fixture in a first plane when desired, and to said housing of said power transfer means to rotate said fixture pole when desired, thereby rotating said lighting fixture in a second plane when desired.
