Abstract
Abstract A combined camera lens cap and lens shade in which a housing having a plurality of swingable flaps thereon is secured to a camera lens. Actuating means is provided to swing the flaps from a closed position where they overlie the front of the lens to form a lens cap to an open position where they extend outwardly from the periphery of the lens to form a lens shade.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
147 words
A combined camera lens cap and lens shade comprising a hollow housing open at each end for attachment to a camera lens, a plurality of flaps hingedly secured to the periphery of the housing opposite the camera lens receiving end thereof, said flaps being interconnected along their adjacent margins by fold lines and swingable from a closed position overlying the end of the housing to which they are secured to an open position substantially coaxial with the said housing end, said flaps being of a size which will cover the housing end to which they are attached when in the closed position and means operatively coupled to at least one of the flaps comprising an elongated groove in the housing, a strip of flexible material secured at one end to said flap and slidably received at its other end within the groove to actuate the said flaps.
Claim 2
Dependent Claim
147 words
A combined camera lens cap and lens shade comprising a hollow housing open at each end for attachment to a camera lens, a plurality of flaps hingedly secured to the periphery of the housing opposite the camera lens receiving end thereof, said flaps being interconnected along their adjacent margins by fold lines and swingable from a closed position overlying the end of the housing to which they are secured to an open position substantially coaxial with the said housing end, said flaps being of a size which will cover the housing end to which they are attached when in the closed position and means operatively coupled to at least one of the flaps comprising an elongated groove in the housing, a strip of flexible material secured at one end to said flap and slidably received at its other end within the groove to actuate the said flaps.
Claim 3
Dependent Claim
56 words
A device according to claim 1 in which the strip is pre-set into an angular configuration so as to conform to the housing and flap when said strip is in the closed position, and an actuating button on the other end of the said strip and means on said button to freely slide within the groove.
Claim 4
Dependent Claim
15 words
A device according to claim 2 in which the strip is of flap spring material.
Claim 5
Dependent Claim
145 words
A combined camera lens cap and lens shade comprising a hollow housing open at each end for attachment to a camera lens, a plurality of flaps hingedly secured to the periphery of the housing opposite the camera lens receiving end thereof, said flaps being individual members swingable from a closed position overlying the end of the housing to which they are secured to an open position substantially coaxial with the said housing end, said flaps being of a size which will cover the housing end to which they are attached when in the closed position and means to actuate said flaps comprising links operatively coupled at one end to the flaps and at their other ends to a ring longitudinally slidable upon the housing, pins at the ring ends of said links, said ring being formed with lost motion slots to receive the said pins.
