Abstract

A projector suspension device for a projector comprises a base to be fixed to a surface on which the projector projects an image, a support member extending from the base and configured to support the projector, and an adjustment mechanism configured to adjust a tilt of the projector.

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

a first turning member configured to adjust a rotation of the third member about the first axis by rotation of the first turning member, and

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

wherein the first turning member and the second turning member are attached to the second member, and

wherein a first rotating pivot of the first turning member and a second rotating pivot of the second turning member are parallel each other.

2. The projector suspension device according to claim 1,

wherein the first turning member and the second turning member are arranged adjacent each other.

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

a first pressing member disposed between the second member and the third member, the first pressing member pressing the second member and the third member.

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

a fourth member connected to the third member, the fourth member configured to rotate with respect to the third member about a third axis that is perpendicular to the first axis and the second axis, and

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

5. The projector suspension device according to claim 4,

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

6. The projector suspension device according to claim 4,

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

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

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

8. The projector suspension device according to claim 7,

wherein the second pressing member is arranged parallel to the third member and the fourth member.

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

a turning pivot member having a turning pivot that is the third axis, the turning pivot member passing through the third member and the fourth member.

10. The projector suspension device according to claim 4, 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.

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

a turning pivot member having a turning pivot that is the third axis, 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.

12. 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 tilt 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, the third member configured to rotate with respect to the second member,

a fourth member connected to the third member, the fourth member configured to rotate with respect to the third member, and

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 fourth member and adjust a position of the projector.

13. The projector suspension device according to claim 12,

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 a slide adjustment of the first member and a rotating adjustment of at least one of the third member and the fourth member has been carried out.

14. 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 tilt of the projector and a position of the projector, the adjustment mechanism including
