Abstract
According to the present disclosure, a projector lift is provided to raise and lower a projector from the ceiling. The projector lift includes a first mount normally coupled to the ceiling, a second mount supporting the projector, a driver configured to raise and lower the second mount and projector, and a stabilizer extending between the first and second mounts.

A projector lift adapted to support a projector from a ceiling, the projector lift comprising,
- a ceiling mount adapted to be coupled to a ceiling of a room,
- a projector mount adapted to support a projector,
- a driver configured to raise and lower the projector mount and projector relative to the ceiling mount, and
- a series of scissor pairs extending between the ceiling mount and the projector mount, the series having an extended length and a retracted length, each of the scissor pairs of the series including first and second scissor links having a length, width, and height and a plurality of couplers positioned to couple the first and second scissor links together and to couple adjacent scissor pairs together, the retracted length of the series being less than the sum of the heights of the first scissor links.
An audio/visual system configured for use in a structure, the system comprising
- an audio/visual component and
- a component lift configured to raise and lower the component, the component lift including a first mount adapted to be coupled to the structure, a second mount adapted to support the component, and a series of scissor pairs extending between the first and second mounts, the series of scissor pairs having a first length when the component is raised and a second length when the component is lowered, the scissor pairs including first and second scissor links coupled to each other to pivot about a pivot axis, the scissor pairs being positioned in a side-by-side relationship in the direction of the pivot axis.
An audio/visual system for use in a structure, the system comprising
- an audio/visual component and
- a series of scissor pairs adapted to be supported by the structure and configured to support the audio/video component, each scissor pair including a first link and a second link pivotably coupled to the first link, at least one pair of first links being pivotably coupled together by a coupler that spans at least one second link.
An audio/visual system configured for use in a structure, the system comprising
- an audio/visual component and
- a series of scissor pairs adapted to be supported by the structure and to support the audio/video component, the series having extended and retracted lengths, the series including a plurality of scissor pairs having extended and retracted heights and means for coupling the plurality of scissor pairs together so that the retracted length of the series is less than the sum of the retracted heights of the scissor pairs.
An audio/visual system comprising
- an audio/visual component and
- a series of scissor pairs positioned to support the audio/visual component, the series of scissor pairs including a first scissor pair and a second scissor pair, the first and second scissors pairs including a first link and a second link pivotably coupled to the first link, the first link of the first scissor pair moving in a first plane during pivoting, the first link of the second scissor pair moving in a second plane during pivoting, at least one of the second links of the first and second scissor pairs being positioned between the first and second planes.
An audio/visual system for use in a structure, the audio/visual system comprising
- an audio/visual component and
- a component lift configured to raise and lower the component, the component lift including a first mount adapted to be supported by the structure, a second mount positioned to support the component, and a driver configured to move the first mount relative to the second mount, the driver including a shaft and at least one strap, rotation of the shaft causing extension and retraction of the strap to move the second mount relative to the first mount.
An audio/visual system for use in a structure, the system comprising
- an audio/visual component and
- a component lift supported by the structure and coupled to the component to raise and lower the component, the component lift including a housing having a first mount adapted to couple to the structure, a second mount coupled to the component, an interior volume, a driver configured to raise and lower the second mount, and a stabilizer configured to stabilize the second mount, the stabilizer being positioned in the interior volume of the housing.
