Abstract
A stacking stand for adjustably supporting at least one visual image projection device relative to a screen. The stacking stand comprises a support member and a support frame for carrying the projection device. The support frame is pivotably mounted on the support member by a ball and socket pivot joint located near the center of mass of the projection device. The pivot joint allows rotation of the support frame about pitch, roll and yaw axes. In addition, fastening means are provided for locking the support frame relative to the support member in various adjusted positions along the pitch, roll and yaw axes. Thus, an image projected by the projection device onto the screen may be superimposed with a target area on the screen by a rotary adjustment of the projection device along the pitch, roll and yaw axes.
Claims15
A stacking stand, suitable for adjustably supporting at least one visual image projection device in a spaced relationship relative to a screen, which comprises:
- (a) a support member, wherein the support member comprises two transversely spaced side members;
- (b) a support frame for carrying and supporting the projection device, wherein the support frame has two outwardly projecting pins each of which are located proximate to one of the side members;
- (c) means for pivotably mounting the support frame on the support member for rotation about a single pivot point on the support member, the mounting means being configured to allow rotation of the support frame relative to a screen around at least a pitch axis and a roll axis, the pitch and roll axes being substantially perpendicular to one another;
- and
- (d) fastening means for releaseably locking the support frame on the support member in various adjusted positions along the pitch and roll axes, whereby a visual image projected from the projection device onto the screen may be superimposed with a target area on the screen by a rotary adjustment of the projection device along the pitch and roll axes, and wherein the fastening means includes:
- (i) slider blocks independently and movably carried on each of the two side members for a vertical sliding movement relative thereto, each of the pins being received in one of the slider blocks to support the support frame thereon;
- and
- (ii) slider block locking members for releasably holding the slider blocks in adjusted positions along the side members, whereby the position of the support frame may be adjusted about the pitch and roll axes by adjusting the vertical position of each of the slider blocks relative to the side members.
A stacking stand, suitable for adjustably supporting at least one visual image projection device in a spaced relationship relative to a screen, which comprises:
- (a) a support member;
- (b) a support frame for carrying and supporting the projection device;
- (c) means for pivotably mounting the support frame on the support member for rotation about a single pivot point on the support member, the mounting means being configured to allow rotation of the support frame relative to a screen around at least a pitch axis and a roll axis, the pitch and roll axes being substantially perpendicular to one another;
- (d) fastening means for releasably locking the support frame on the support member in various adjusted positions along the pitch and roll axes;
- and
- (e) wherein the support frame includes means for adjusting the projection device about a yaw axis, the yaw axis being mutually perpendicular to both the pitch and roll axes, wherein the support frame comprises:
- (i) a projector cradle for receiving the projecting device therein;
- (ii) a yoke carried with the projector cradle, the yoke being movably mounted relative to the projector cradle about the yaw axis and being fixed relative to the projector cradle about the pitch and roll axes, the yoke having transversely spaced outer ends which are attached to the fastening means to allow the pitch and roll adjustment of the support frame by adjustment of the ends of the yoke;
- and
- (iii) projector cradle locking means extending between the yoke and the projector cradle for locking the projector cradle relative to the yoke in various adjusted positions about the yaw axis, whereby a visual image projected from the projection device onto the screen may be superimposed with a target area on the screen by a rotary adjustment of the projection device along the pitch, roll, and yaw axes.
A stacking stand, suitable for adjustably supporting at least one visual image projection device in a spaced relationship relative to a screen, which comprises:
- (a) a support member;
- (b) a support frame for carrying and supporting the projection device;
- (c) a ball and socket pivot joint means for pivotably mounting the support frame on the support member for rotation in three degrees of freedom about the ball and socket pivot joint means, the ball and socket pivot joint means being configured to allow rotation of the support frame relative to a screen around pitch, roll, and yaw axes, the pitch, roll and yaw axes being substantially and mutually perpendicular to one another;
- and
- (d) fastening means for releasably locking the support frame relative to the support member in various adjusted positions along the pitch, roll, and yaw axes, whereby a visual image projected from the projection device onto the screen may be superimposed with a target area on the screen by a rotary adjustment of the projection device along the pitch, roll, and yaw axes.
A stacking stand, suitable for adjustably supporting a plurality of visual image projection devices in a spaced relationship relative to a screen, which comprises:
- (a) a support member;
- (b) a plurality of support frames for respectively carrying and supporting the plurality of visual image projection devices thereon, each support frame having a plurality of sides between which the visual image projection device is contained;
- (c) a plurality of ball and socket pivot joint means for pivotably mounting each of the respective support frames on the support member in a vertically spaced manner, the ball and socket pivot joint means being configured to allow rotation of each support frame relative to the screen about at least a pitch axis and a roll axis, the pitch and roll axes being mutually perpendicular to one another;
- and
- (d) fastening means for releasably locking each of the support frames relative to the support member in various adjusted positions along both the pitch and roll axes, the fastening means being located proximate to one or more sides of each support frame to allow easy access to the fastening means such that the vertical spacing between support frames can be minimized, whereby one of the projection devices projects a target image onto the screen which defines a target area to which images from the other projection devices are superimposed by rotary adjustment of the other projection devices along the pitch and roll axes.
