Abstract

Abstract A motor driven panoramic mounting for cameras which provides an automatic pan range and the ability to pan over 360 degrees. Mechanical actuators on a fixed base act upon a turnstile on a shaft on the rotating table, with the turnstile shaft also rotating two cams that actuate three limit switches. One cam acts upon a single limit switch which determines the automatic range and reverses the table motion at the ends of the automatic range. The other cam acts on two end limit switches which stop the motion. The action of the turnstile and switches brings the table back to the preset automatic range regardless of where it is directed when it placed back in the automatic mode.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 323 words
A camera panning control apparatus comprising; a base means; a rotatable table to which a camera can be attached, the table located in a plane essentially parallel to the base means; an electrical motor mechanically coupled to and rotating the table; at least first, second and third limit stops attached to and protruding from the base means; a shaft attached to the table and rotatable relative to the table; a turnstile constructed with at least first, second third and fourth gates, the turnstile being attached to the shaft and being located so that each gate comes in contact with at least one of the limit stops as the table rotates; first and second cams mechanically coupled to the shaft and rotating in synchronism with the turnstile, each of the cams having both plateau and depression regions; an electrical reversing switch connected to the motor so that the motor reverses its direction of rotation when the reversing switch changes its condition, the reversing switch located in a fixed position relative to the first cam having an actuator in contact with the first cam, and oriented so that the reversing switch changes its condition when the first cam rotates and the reversing switch actuator moves between a plateau and a depression on the first cam; and electrical first and second end limit switches connected to the motor so electrical power to move the motor in one direction is interrupted by the first end limit switch when it changes condition, and electrical power to move the motor in the other direction is interrupted by the second end limit switch when it changes condition, each end limit switch being located in a fixed position relative to the second cam, having an actuator in contact with the second cam, and being oriented so that it changes its condition when the second cam rotates and the switch actuator moves between a plateau and a depression on the second cam.
Claim 2
Dependent Claim 323 words
A camera panning control apparatus comprising; a base means; a rotatable table to which a camera can be attached, the table located in a plane essentially parallel to the base means; an electrical motor mechanically coupled to and rotating the table; at least first, second and third limit stops attached to and protruding from the base means; a shaft attached to the table and rotatable relative to the table; a turnstile constructed with at least first, second third and fourth gates, the turnstile being attached to the shaft and being located so that each gate comes in contact with at least one of the limit stops as the table rotates; first and second cams mechanically coupled to the shaft and rotating in synchronism with the turnstile, each of the cams having both plateau and depression regions; an electrical reversing switch connected to the motor so that the motor reverses its direction of rotation when the reversing switch changes its condition, the reversing switch located in a fixed position relative to the first cam having an actuator in contact with the first cam, and oriented so that the reversing switch changes its condition when the first cam rotates and the reversing switch actuator moves between a plateau and a depression on the first cam; and electrical first and second end limit switches connected to the motor so electrical power to move the motor in one direction is interrupted by the first end limit switch when it changes condition, and electrical power to move the motor in the other direction is interrupted by the second end limit switch when it changes condition, each end limit switch being located in a fixed position relative to the second cam, having an actuator in contact with the second cam, and being oriented so that it changes its condition when the second cam rotates and the switch actuator moves between a plateau and a depression on the second cam.
Claim 3
Dependent Claim 76 words
The camera panning control apparatus of claim 1 further including an end section on one of the gates on the turnstile, the end section acting so that, when the gate on which it is included contacts a limit stop attached to the base means, the end section traps the limit stop and prevents further movement of both the turnstile and the table in the direction which caused the contact between the limit stop and the gate.
Claim 4
Dependent Claim 32 words
The camera panning control apparatus of claim 1 further including a manual-automatic switch to disconnect the reversing limit switch from the motor and connect a manual direction control switch to the motor.
Claim 5
Dependent Claim 197 words
A camera panning control apparatus comprising; a base means; a rotatable table to which a camera can be attached, the table located in a plane essentially parallel to the base means; an electrical motor mechanically coupled to and rotating the table; at least first and second limit stops attached to and protruding from the base means; a shaft attached to the table and rotatable relative to the table; a turnstile constructed with at least one gate, the turnstile being attached to the shaft and being located so that the gate comes in contact with the limit stops as the table rotates; a cam mechanically coupled to the shaft and rotating in synchronism with the turnstile, the cam having both plateau and depression regions; and an electrical reversing switch connected to the motor so that the motor reverses its direction of rotation when the reversing switch changes its condition, the reversing switch located in a fixed position relative to the cam, having an actuator in contact with the cam, and oriented so that the reversing switch changes its condition when the cam rotates and the reversing switch actuator moves between a plateau and a depression on the cam.
Claim 6
Dependent Claim 197 words
A camera panning control apparatus comprising; a base means; a rotatable table to which a camera can be attached, the table located in a plane essentially parallel to the base means; an electrical motor mechanically coupled to and rotating the table; at least first and second limit stops attached to and protruding from the base means; a shaft attached to the table and rotatable relative to the table; a turnstile constructed with at least one gate, the turnstile being attached to the shaft and being located so that the gate comes in contact with the limit stops as the table rotates; a cam mechanically coupled to the shaft and rotating in synchronism with the turnstile, the cam having both plateau and depression regions; and an electrical reversing switch connected to the motor so that the motor reverses its direction of rotation when the reversing switch changes its condition, the reversing switch located in a fixed position relative to the cam, having an actuator in contact with the cam, and oriented so that the reversing switch changes its condition when the cam rotates and the reversing switch actuator moves between a plateau and a depression on the cam.
