摘要

A security cover device for a door viewer inserted into a door includes a housing configured to couple to a door with a door viewer, an eye piece movably coupled with the housing, and a shutter assembly. The shutter assembly includes a shutter member disposed within the housing, the shutter being configured to alter the amount of light passing through the housing, and an actuator in communication with the shutter member to selectively reposition the shutter member with respect to the housing from a first shutter member position to a second shutter member position, wherein the actuator is actuated to reposition the shutter member in response to the eye piece being moved in relation to the housing.

1. A security cover device for a door viewer inserted into a door, the security device comprising:
a housing configured to couple to the door with the door viewer; an eyepiece movably coupled with the housing; and a shutter assembly comprising:
one or more shutter members disposed within the housing, each shutter member being movable in response to movement of the eyepiece and also being configured to alter the amount of light passing through the housing; andan actuator coupled with the eyepiece and each shutter member to move each shutter member with respect to the housing from a first position to a second position when the eyepiece is moved in a linear direction toward each shutter member and from the second position to the first position when the eyepiece is moved in a linear direction away from each shutter member, wherein the actuator effects radial and pivotal movement of each shutter member between the first and second positions such that each shutter member rotates about an axis that is parallel with a linear axis of movement of the eyepiece.
