Abstract

A projector suspension device comprising a base fixed to a wall, a support member extending from the base and supporting the projector, and an adjustment mechanism that adjusts a tilt and position of the projector, the adjustment mechanism including a first member that slides with respect to the support member in a first direction perpendicular to the wall and adjusts the position of the projector in the first direction, a second member fixed to the first member, a third member connected to the second member, a fourth member connected to the third member and that rotates with respect to the third member about an axis parallel to the wall and perpendicular to the first direction, and a turning member that adjusts a rotation of the fourth member about the axis by rotation of the turning member, wherein a rotating pivot of the turning member is perpendicular to the base.

Claims

1. A projector suspension device for a projector comprising:

a base configured to be fixed to a wall surface;

a support member extending from the base, the support member configured to support the projector; and

an adjustment mechanism configured to adjust a rotation of the projector and a position of the projector, the adjustment mechanism including

a first member configured to slide with respect to the support member in a first direction perpendicular to the wall surface and adjust the position of the projector in the first direction,

a second member configured to be fixed to the first member,

a third member connected to the second member,

a fourth member connected to the third member, the fourth member configured to rotate with respect to the third member about an axis that is parallel to the wall surface and perpendicular to a plane surface of the second member, and

a turning member configured to adjust a rotation of the fourth member about the axis by rotation of the turning member,

wherein a rotating pivot of the turning member is perpendicular to the base.

2. The projector suspension device according to claim 1,

wherein the rotating pivot of the turning member is parallel to the first direction.

4. The projector suspension device according to claim 1, the adjustment mechanism further including

a fifth member connected to the fourth member, the fifth member configured to fix the projector,

wherein the fifth member is configured to slide with respect to the fourth member and adjust the position of the projector.

5. The projector suspension device according to claim 4,

wherein the fifth member is configured to further adjust the position of the projector in a state of the projector in which at least one of an adjustment of the position by the first member and an adjustment of the rotation of the fourth member by the turning member has been carried out.

6. The projector suspension device according to claim 1, the adjustment mechanism further including

a stopper connected to the turning member, the stopper configured to contact with the fourth member in a side of the stopper, the side being a side that the stopper is connected to the turning member,

wherein the fourth member is configured to rotate about the axis by change of a position of the stopper with respect to the third member.

7. The projector suspension device according to claim 1, the adjustment mechanism further including

a pressing member disposed between the third member and the fourth member, the pressing member pressing the third member and the fourth member.

8. The projector suspension device according to claim 1, the adjustment mechanism further including

a turning pivot member having a turning pivot that is the axis parallel to the wall surface and perpendicular to the plane surface of the second member, the turning pivot member passing through the third member and the fourth member.

9. The projector suspension device according to claim 1, the adjustment mechanism further including

a turning limit member configured to limit the rotation of the fourth member, the turning limit member passing through the fourth member.

10. The projector suspension device according to claim 9, the adjustment mechanism further including

a turning pivot member having a turning pivot that is the axis parallel to the wall surface and perpendicular to the plane surface of the second member, the turning pivot member passing through the third member and the fourth member,

wherein the turning limit member passes through a slot which is formed around the turning pivot member, and

wherein the turning limit member is configured to slide along the slot in accordance with the rotation of the fourth member.
