Dome camera mechanism
View Patent ↗A dome camera mechanism for an improved gimbal pan assembly which allows rotation of an optical module of the dome camera over 360 degrees in a pan direction using a track and a guide.
1. Apparatus comprising:
a yoke configured to mount an optical module of a camera, the yoke including a disk having a circular perimeter, and the disk defining a track that traces a path extending over 360 degrees alongside the circular perimeter; and
a gimbal base configured to mount the yoke, and the gimbal base including a guide, and
when the yoke is mounted on the gimbal base, the guide and the track cooperatively limit an amount of rotation of the yoke, relative to the gimbal base, in a pan direction, wherein the track limits the rotation of the yoke relative to the base to an amount more than 360 degrees but less than 380 degrees.
2. The apparatus of claim 1 , wherein the guide comprises a pin which moves in the track and stops the rotation of the yoke in a direction that opposes an end of the track.
3. The apparatus of claim 2 , wherein the track is a spiral track.
4. Apparatus comprising:
a yoke configured to mount an optical module of a camera, the yoke including a disk having a circular perimeter, and the disk defining a track that traces a path extending over 360 degrees alongside the circular perimeter; and
a gimbal base configured to mount the yoke, and the gimbal base including a guide, and
when the yoke is mounted on the gimbal base, the guide and the track cooperatively limit an amount of rotation of the yoke, relative to the gimbal base, in a pan direction, and
wherein the guide further comprises a cantilever and a pin, with the pin at one end of the cantilever.
5. The apparatus of claim 4 , wherein the pin moves in the track and stops the rotation of the yoke in a direction that opposes an end of the track.
6. The apparatus of claim 5 , wherein the track is a spiral track.
7. Apparatus comprising:
a gimbal base including a yoke-mounting region defined interiorly within a circular perimeter on a surface of the gimbal base;
a track being defined within the yoke-mounting region of the gimbal base, the track tracing a path extending over 360 degrees alongside the circular perimeter; and
a yoke configured to mount an optical module of a camera, the yoke including a disk that includes a guide; and
when the yoke is mounted on the gimbal base, the guide and the track cooperatively limit an amount of rotation of the yoke, relative to the gimbal base, in a pan direction, wherein the track limits the rotation of the yoke relative to the base to an amount more than 360 degrees but less than 380 degrees.
8. The apparatus of claim 7 , wherein the guide comprises a pin which moves in the track and stops the rotation of the yoke in a direction that opposes an end of the track.
9. The apparatus of claim 8 , wherein the track is a spiral track.
10. Apparatus comprising:
a gimbal base including a yoke-mounting region defined interiorly within a circular perimeter on a surface of the gimbal base;
a track being defined within the yoke-mounting region of the gimbal base, the track tracing a path extending over 360 degrees alongside the circular perimeter; and
a yoke configured to mount an optical module of a camera, the yoke including a disk that includes a guide; and
when the yoke is mounted on the gimbal base, the guide and the track cooperatively limit an amount of rotation of the yoke, relative to the gimbal base, in a pan direction, and
wherein the guide further comprises a cantilever and a pin, with the pin at one end of the cantilever.
11. The apparatus of claim 10 , wherein the pin moves in the track and stops the rotation of the yoke in a direction that opposes an end of the track.
12. The apparatus of claim 11 , wherein the track is a spiral track.
