Abstract

A tilting device includes: an upper movable plate arranged on a side on which an object T to be tilted is arranged; an intermediate movable plate connected to the upper movable plate in a rotatable manner via an upper rotation shaft; a first actuator; a first lower movable plate connected to the intermediate movable plate in a rotatable manner via a first lower rotation shaft; a second actuator; and a first connecting member that is connected to the upper movable plate in a rotatable manner via a first connecting rotation shaft at an end portion on a side of a first direction, and that is connected to the first lower movable plate in a rotatable manner via a second connecting rotation shaft at an end portion on a side of a second direction opposite to the first direction.

First claim

What is claimed is:

1. A tilting device, comprising:
an upper movable plate arranged on a side on which an object to be tilted is arranged;
an intermediate movable plate arranged below the upper movable plate and connected to the upper movable plate in a rotatable manner via an upper rotation shaft;
a first actuator arranged between the upper movable plate and the intermediate movable plate;
a first lower movable plate arranged below the intermediate movable plate and connected to the intermediate movable plate in a rotatable manner via a first lower rotation shaft;
a second actuator arranged between the intermediate movable plate and the first lower movable plate; and
a first connecting member that is connected to the upper movable plate in a rotatable manner via a first connecting rotation shaft at an end portion on a side of a first direction opposite to an end portion at which the upper movable plate is connected to the intermediate movable plate, and that is connected to the first lower movable plate in a rotatable manner via a second connecting rotation shaft at an end portion on a side of a second direction opposite to the first direction, wherein the first connecting rotation shaft of the first connecting member and the upper movable plate is arranged substantially coaxially with the first lower rotation shaft of the intermediate movable plate and the first lower movable plate, and
the second connecting rotation shaft of the first connecting member and the first lower movable plate is arranged substantially coaxially with the upper rotation shaft of the upper movable plate and the intermediate movable plate.

2. The tilting device according to claim 1 , wherein the first connecting member is a rod and is configured to extend in a direction intersecting the upper rotation shaft and the first lower rotation shaft in a plan view.

3. The tilting device according to claim 1 , wherein the first connecting member is arranged at an end portion of the upper movable plate and an end portion of the first lower movable plate in a third direction which is on one side of a direction orthogonal to the first direction and the second direction in a plan view.

4. The tilting device according to claim 3 , wherein a length of the upper movable plate in a direction along the upper rotation shaft is larger than a length of the inteiiiiediate movable plate in a direction along the upper rotation shaft, and a length of the first lower movable plate in a direction along the first lower rotation shaft is larger than a length of the intermediate movable plate in a direction along the first lower rotation shaft,
the first connecting rotation shaft is arranged on an end portion side of the upper movable plate and more outward than the first lower rotation shaft in the third direction, and
the second connecting rotation shaft is arranged on an end portion side of the first lower movable plate and more outward than the upper rotation shaft in the third direction.

5. The tilting device according to claim 4 , further comprising:
a first protrusion of the upper movable plate, which is arranged more outward than the first lower rotation shaft in the third direction and protrudes downward from the upper movable plate toward the first lower movable plate; and
a second protrusion of the first lower movable plate, which is arranged more outward than the upper rotation shaft in the third direction and protrudes upward from the first lower movable plate toward the upper movable plate,
wherein the first connecting rotation shaft is arranged at an end portion on the lower side of the first protrusion, and
the second connecting rotation shaft is arranged at an end portion on the upper side of the second protrusion.

6. A tilting device, comprising:
an upper movable plate arranged on a side on which an object to be tilted is arranged;
an intermediate movable plate arranged below the upper movable plate and connected to the upper movable plate in a rotatable manner via an upper rotation shaft;
a first actuator arranged between the upper movable plate and the intermediate movable plate;
a first lower movable plate arranged below the intermediate movable plate and connected to the intermediate movable plate in a rotatable manner via a first lower rotation shaft;
a second actuator arranged between the intermediate movable plate and the first lower movable plate;
a first connecting member that is connected to the upper movable plate in a rotatable manner via a first connecting rotation shaft at an end portion on a side of a first direction opposite to an end portion at which the upper movable plate is connected to the intermediate movable plate, and that is connected to the first lower movable plate in a rotatable manner via a second connecting rotation shaft at an end portion on a side of a second direction opposite to the first direction;
a second lower movable plate arranged below the first lower movable plate and connected to the first lower movable plate in a rotatable manner via a second lower rotation shaft;
a third actuator arranged between the first lower movable plate and the second lower movable plate;
a third lower movable plate arranged below the second lower movable plate and connected to the second lower movable plate in a rotatable manner via a third lower rotation shaft;
a fourth actuator arranged between the second lower movable plate and the third lower movable plate; and
a second connecting member that is connected to the first lower movable plate in a rotatable manner via a third connecting rotation shaft at an end portion on one side of a direction orthogonal to the first direction in a plan view, and that is connected to the third lower movable plate in a rotatable manner via a fourth connecting rotation shaft at an end portion on the other side of the direction orthogonal to the first direction in the plan view.

7. A tilting device, comprising:
an upper movable plate arranged on a side on which an object to be tilted is arranged;
an intermediate movable plate arranged below the upper movable plate and connected to the upper movable plate in a rotatable manner via an upper rotation shaft;
a first actuator arranged between the upper movable plate and the intermediate movable plate;
a first lower movable plate arranged below the inteiiiiediate movable plate and connected to the intermediate movable plate in a rotatable manner via a first lower rotation shaft;
a second actuator arranged between the intermediate movable plate and the first lower movable plate; and
a first connecting member that is connected to the upper movable plate in a rotatable manner via a first connecting rotation shaft at an end portion on a side of a first direction opposite to an end portion at which the upper movable plate is connected to the intermediate movable plate, and that is connected to the first lower movable plate in a rotatable manner via a second connecting rotation shaft at an end portion on a side of a second direction opposite to the first direction, wherein the first actuator comprises a first expansion/contraction bag capable of expanding and contracting by supply and exhaustion of gas,
