Abstract
The present disclosure is directed to a lens cap with an integrated iris that screws onto a camera lens. Once secured on a camera lens, the iris may be opened by rotating an outer edge of the lens cap in a first direction. When in an open position, the entire surface of the camera lens is free from obstruction and photos may be taken as if the lens cap were not even there. The iris can literally disappear within an edge of circular lens cap. By rotating the lens cap in an opposite direction, the lens may be completely covered by the integrated iris again. For example, the iris may be opened by rotating the lens cap in a clockwise direction and then closed again by rotating the lens cap in a counter clockwise direction. Once installed, this lens cap never has to be removed.
Claims11
A lens cover comprising:
- (a) a cover portion having exterior threads for attachment to complementary threads of a camera lens;
- (b) an iris mechanism configured at least in part in the cover portion, the iris mechanism having a plurality of blades comprising an iris;
- (c) a control mechanism such that a user can interact with the control mechanism to open the iris to use the camera lens or to close the iris to protect the camera lens;
- (d) a first set of coupling mechanisms coupled to the cover portion, wherein the cover portion is part of an inner circular portion that includes the first set of coupling mechanisms;
- (e) a plurality of couplers that attach the plurality of blades to the cover portion, wherein:
- (i) each the plurality of couplers are attached to at least one blade of the plurality of blades,
- (ii) the plurality of couplers mate with the first set of coupling mechanisms to attach the iris mechanism to the cover portion, and
- (iii) the iris mechanism includes a first set of features of a first camming mechanism that is coupled to the control mechanism;
- (f) a second set of features of the first camming mechanism, the second set of features coupling the iris mechanism to the control mechanism, wherein
- (i) rotation of the control mechanism forces relative motion between each respective blade of the plurality of blades based on the first camming mechanism, thereby generating a circular aperture of increasing size around a center portion of the camera lens, and
- (ii) the aperture increases in size until each of the plurality of blades retract to a critical circular size;
- and
- (g) an arm that includes a first part of a second camming mechanism that rotates the arm to a center position of the lens cover when the iris mechanism is in a closed position.
