Abstract
The present invention involves a projector mount and micro adjustment capability which allows a projector to be mounted to fixed object (f ex ceiling), rough adjustment to be made with the ceiling mount and then fine adjustments to be made by a micro adjusting mechanism. The micro adjustor provides for a fluid pitch, yaw and roll adjustment without hanging up in place, which might throw off the adjustments. An installation and alignment tool is also provided. A method of adjustment and installation is also disclosed.
Claims12
A mounting and micro adjustment system connecting equipment to a mounting surface, comprising:
- a) a domed hemispherical base element, having an inner and outer surfaces and a generally central aperture;
- b) a second hemispherical intermediate element having an inner and outer surfaces said inner surface being sized to receive said outer surface of said base element therein, in slideable contact therewith and having a generally central aperture;
- c) a third hemispherical top element having inner and outer surfaces, said inner surface sized to receive said outer surface of said intermediate element in slideable contact therewith and having a generally central aperture;
- d) a central collar element having a generally cylindrical portion sized to be received thru said central apertures, and a hemispherical outer surface sized to be received at least partly within and in slideable relation with the inner surface of the base element;
- e) first guides located between said base and intermediate elements for limiting the movement between said elements along the path defined by said first guides, thereby defining movement in a first orientation;
- f) second guides located between said intermediate and top elements for limiting the movement between said elements along a path defined by said second guides, thereby defining movement in a second orientation;
- g) third guides located between said top and collar elements for limiting the movement between said elements along a path defined by said second guides, thereby defining movement in a third orientation;
- h) first continuous screw adjustable link between said base and intermediate elements, said link configured to move said base and intermediate elements relative to each other along the path of said first guide;
- i) second continuous screw adjustable link, offset from said first link by 90 degrees, between said intermediate and top elements, said link configured to move said intermediate and top elements relative to each other along the path of said second guide;
- j) third continuous screw adjustable link, offset from at least one of said first or second link by 90 degrees, between said collar and top elements, said link configured to move said collar and top elements relative to each other along the path of said third guide,
- so that movement of each link controls the positioning of the collar.

A mounting and tightening tool system for a projector mount comprising:
- a. a mount having an inner and outer surface and a central aperture defining a central axis;
- and a threaded pipe receiving fixture at said central aperture to be mounted along said central axis;
- b. said inner surface including a plurality of engagement members spaced around said aperture;
- c. an installation tool sized and shaped to be removeably received within said inner surface and having mating members sized and shaped to received said engagement members, said tool including a central keyed aperture sized to receive a cranking tool
- so that, when said tool is inserted into said inner surface it mates with said engagement members and can be rotated by said cranking tool so that said mount is threaded onto said pipe without applying force to the outer surface of the mount.

A combination and tightening tool system for affixing a projector mount to a fixed surface, comprising:
- a. a mount having an inner and outer collar surface and a pipe threaded receiving central aperture defining a central axis;
- b. said inner surface including a plurality of engagement members spaced around said aperture;
- c. an installation tool sized and shaped to be removeably received within said inner surface and having mating members sized and shaped to received said engagement members, said tool including a central keyed aperture sized to receive a cranking tool and at least one other aperture therethrough;
- so that the tool has two modes of use, either when said tool is inserted into said inner surface it mates with said engagement members and can either be rotated by said cranking tool so that said mount is threaded onto said pipe without applying force to the outer surface of the mount, or when the tool functions as a mounting plate by pressing the mount to the fixed surfaces when the tool is affixed to the surfaces through at least one aperture.
