Abstract

A camera is configured for use with a removable camera lens cover, which can be secured to or removed from the camera by a user without the use of a tool set. The mechanism which allows the lens cover to be secured to and removed from the camera includes a set of wires embedded into the lens cover and a set of wedges protruding from the lens wall of the camera. To secure the lens cover to the camera, the lens cover is placed onto the front of the camera and rotated until the wires align with corresponding wedges, securing the wires underneath the tapered surface of the wedges. To remove the lens cover from the camera, a force is applied outward and normal to the lens cover, causing the wires to flex outward and enabling the rotation and removal of the lens cover from the camera.

First claim

The invention claimed is:

1. A camera system comprising:
a camera comprising:
a lens protruding from a front surface of the camera;
a lens wall surrounding the lens, the outer lens wall comprising an outside surface;
a set of wedges protruding from and tapered towards the outside surface of the lens wall, each wedge comprising a wedge surface angled relative to the outside surface of the outer lens wall; and

a removable lens cover comprising:
a lens hole within a rear surface of the removable lens cover, the lens hole configured to enclose the lens when the removable lens cover is secured to the camera;
a protective lens surface within a front surface of the removable lens cover; and
a set of flexible securing structures, each of the set of flexible securing structures configured to align with a corresponding different wedge of the set of wedges such that 1) when the removable lens cover is secured to the camera, the securing structures prevent the removable lens cover from rotating relative to the camera or being removed from the camera, and 2) when a threshold force is applied on the removable lens cover away from and normal to the front surface of the camera, a reciprocal force is applied by the set of wedges onto the securing structures, causing the securing structures to flex outward and away from each other, thereby enabling the rotation of the removable lens cover relative to and removal of the removable lens cover from the camera.

2. The camera system of claim 1 , wherein the removable lens cover is substantially rectangular in shape with rounded corners.

3. The camera system of claim 1 , wherein the removable lens cover may include an outer wall with a top segment, a bottom segment, a left segment, and a right segment.

4. The camera system of claim 3 , wherein the protective lens surface is affixed to the outer wall.

5. The camera system of claim 1 , wherein the camera and the removable lens cover can be configured in an unlocked configuration such that the removable lens cover can be removed from or rotated relative to the camera.

6. The camera system of claim 5 , wherein the removable lens cover in the unlocked configuration can be rotated clockwise or counter-clockwise relative to the camera to configure the removable lens cover in a locked configuration.

7. The camera system of claim 1 , wherein the camera and the removable lens cover can be configured in a locked configuration such that the removable lens cover is secured to the camera and prevented from rotating relative to the camera.

8. The camera system of claim 1 , wherein the removable lens cover contains a hole within the rear surface of the lens cover that aligns with the lens of the camera in a locked configuration.

9. The camera system of claim 1 , wherein two segments of the removable lens cover are either substantially parallel or are substantially flush with two surfaces of the camera when the removable lens cover is in a locked configuration.

10. The camera system of claim 1 , wherein the set of flexible securing structures comprise one or more of: wires, rods, cylinders, pins, and dowels.

11. The camera system of claim 10 , wherein each end of a flexible securing structure is embedded into a different one of a corresponding pair of partial channels on the rear surface of the removable lens cover.

12. The camera system of claim 11 , wherein the pair of partial channels are substantially collinear.

13. The camera system of claim 11 , wherein the pair of partial channels are separated by a clearance space.

14. The camera system of claim 11 , wherein each end of the flexible securing structure is secured into a partial channel with a securing mechanism.

15. The camera system of claim 1 , wherein each wedge secures a corresponding flexible securing structure underneath the tapered surface of the wedge when the removable lens cover is in a locked configuration.

16. The camera system of claim 1 , wherein the camera further comprises a plurality of grooves within the front surface of the camera, and wherein the removable lens cover further comprises a corresponding plurality of notches protruding from the rear surface of the removable lens cover such that when the removable lens cover is secured to camera, each of the plurality of notches is aligned with and inserted into a corresponding groove.

17. The camera system of claim 1 , wherein a portion of the outer wall of the removable lens cover comprises a thermally conductive material.

18. The camera system of claim 17 , wherein the camera further comprises a chipset and a thermal conduit thermally coupled to the chip set and to the lens wall such that heat from the chipset is transferred to the thermal conduit, to the lens wall, and to the portion of the outer wall of the removable lens cover when the removable lens cover is secured to the camera.

19. A camera system comprising:
a camera comprising a lens and a first set of securing structures; and
a removable lens cover comprising:
a protective lens surface; and
a second set of flexible securing structures, each of the second set of flexible securing structures configured to align with a corresponding different securing structure of the first set of securing structures such that when the removable lens cover is configured in a locked configuration, the first set of securing structures and the second set of securing structures prevent the removable lens cover from rotating relative to the camera or being removed from the camera, and such that when a threshold force is applied to the removable lens cover away from the camera, the first set of securing structures and the second set of securing structure do not prevent the removable lens cover from rotating relative to the camera or being removed from the camera.
