Abstract

A rotary support apparatus is provided that includes a rotation mechanism, a support mechanism, an object detector and a controller. The rotation mechanism is configured to rotatably support a supported body between a first position and a second position. The support mechanism is configured to support the supported body with at least a two stage support force at the first position. The object detector is configured to detect a person or an object. The controller is configured to control the support mechanism so as to switch the support force based on the results detected by the object detector.

Claims

1. A rotary support apparatus comprising:

a rotation mechanism configured to rotatably support a supported body between a first position and a second position, the supported body being provided on a movable vehicle;

a support mechanism configured to support the supported body with at least a two stage support force at the first position;

an object detector disposed near the supported body, the object detector being configured to detect a person or an object; and

a controller configured to control the support mechanism so as to switch the support force based on the results detected by the object detector.

2. The rotary support apparatus according to claim 1, wherein

when the object detector detects a person or an object, the controller controls the support mechanism so as to support the supported body at a lower support force of the at least two stage support force.

3. The rotary support apparatus according to claim 1, wherein

when the object detector does not detect a person or an object, the controller controls the support mechanism so as to support the supported body at a higher support force of the at least two stage support force.

4. The rotary support apparatus according to claim 1, wherein

the object detector is configured to detect the distance between the supported body and the person or the object, and

the controller is configured to control the support mechanism so that the support force decreases in proportion to the detected distance.

5. The rotary support apparatus according to claim 1, further comprising:

a variable voltage circuit configured to vary the amount of voltage supplied to the support mechanism, wherein

the support mechanism is configured to switch the support force based on the supplied voltage, and

the variable voltage circuit is configured to vary the amount of voltage supplied to the support mechanism based on the results detected by the object detector.

6. The rotary support apparatus according to claim 1, wherein

the rotation mechanism rotates the supported body from the second position to the first position when power is being supplied and toward the second position when no power is being supplied.

7. The rotary support apparatus according to claim 1, wherein

the supported body is a display device disposed on the ceiling of the movable vehicle.

8. The rotary support apparatus according to claim 1, further comprising:

a position detection mechanism configured to detect the position of the supported body, wherein

the rotation mechanism rotates the supported body toward the second position when the position detection mechanism has detected that the supported body has been rotated from the first position by at least a specific amount.

9. A rotary support apparatus on a movable vehicle comprising:

a supported body rotably movable between a first position and a second position;

a rotation mechanism configured to rotatably support the supported body between the first position and the second position;

a biasing member configured to exert a biasing force upon the supported body, the biasing force urging the supported body towards the second position;

a support mechanism configured to support the supported body against the biasing force at the first position, the support mechanism producing at least a two stage support force;

the two stage support force including a first support force and a second support force;

an object detector disposed near the supported body, the object detector being configured to detect a person or an object; and

a controller configured to;

determine which support force to exert based upon the results detected by the object detector, and

control the support mechanism to switch from the first support force to the second support force based on the determination.
