Camera lens hood

Claim 2

A shock resistant lens hood and cover for a camera having a shroud surrounding a lens comprising a rigid mounting member adapted for attachment to said shroud, a flexible hood carried by said mounting member for rotation about the axis of said lens, a flexible cover, a frame assembly, cooperating means on said frame assembly and said cover for securing said frame assembly to the central portion of said cover, means mounting said frame assembly on said hood for pivotal movement about an axis displaced a substantial distance rearwardly of the outer end of said hood whereby said cover may be moved between a closed position in which said cover sealingly engages the end of said hood remote from said member and an open position in which said cover is out of the field of said lens and upon movement of said cover to said open position said cover is displaced outwardly and rearwardly of said hood, and cooperating means on said frame and said hood for retaining said cover in a selected open position or in closed position, said frame assembly applying closing pressure to the cover centrally thereof to assure a tight peripheral seal.

Claim 3

The combination according to claim 1 wherein said mounting member has an outwardly projecting peripheral flange and said hood has a peripheral groove fitting over said flange with a light friction fit to retain said hood against axial displacement and yet permit free rotation of said hood on said mounting member.

Claim 4

The combination according to claim 1 wherein said hood and said cover have outwardly and inwardly facing tapered sealing surfaces, respectively, adapted to be sealingly engaged when said cover is moved to said closed position.

Claim 5

The combination according to claim 1, wherein the mounting means for said frame comprises a pair of aligned inturned fingers on said frame assembly rotatably received in bosses on said hood.

Claim 6

The combination according to claim 1, wherein the last-mentioned means comprises detents formed on said cover engagable by a portion of said frame assembly.

Claim 7

The combination according to claim 1, together with an operating arm carried by same frame assembly and extending rearwardly toward said camera to facilitate displacement of said cover between open and closed positions.

Claim 8

The combination according to claim 1, wherein said cover is of essentially square conFiguration and on its inner surface is provided with a circular recess surrounded by a peripheral sealing lip.

Claim 9

A shock resistant lens hood and cover for camera having a shroud surrounding a lens comprising, a rigid mounting member adapted for attachment to said shroud, a flexible hood carried by said mounting member for rotation about the axis of said lens, said hood terminating at its outer end in an outwardly facing tapered sealing surface, a flexible cover having a recessed central portion surrounded by a peripheral lip having an inwardly facing tapered sealing surface adapted to sealingly engage the sealing surface on said hood, means forming a boss on the outer surface of said cover centrally thereof, a spring frame assembly having a portion adapted to frictionally engage said boss and having a pair of spring arms extending toward the marginal edges of said cover, said spring arms terminating in aligned inturned fingers rotatably received in bosses on said housing, means on said hood for retaining said spring frame in any position to which it is moved, whereby said spring frame assembly pivotally supports said cover on said hood for movement between a closed position in which spring frame urges said cover into sealing engagement with the end of said hood remote from said member and an open position in which said cover is out of the field of said lens, and means on said cover for preventing outward spreading movement of said spring arms to retain said spring frame assembly in engagement with the boss on said cover and to maintain said inturned fingers in said bosses on said housing.

Claim 10

A shock resistant lens hood and cover for camera having a shroud surrounding a lens comprising, a rigid mounting member adapted for attachment to said shroud, a flexible hood carried by said mounting member for rotation about the axis of said lens, said hood terminating at its outer end in an outwardly facing tapered sealing surface, a flexible cover having a recessed central portion surrounded by a peripheral lip having an inwardly facing tapered sealing surface adapted to sealingly engage the sealing surface on said hood, means forming a boss on the outer surface of said cover centrally thereof, a spring frame assembly having a portion adapted to frictionally engage said boss and having a pair of spring arms extending toward the marginal edges of said cover, said spring arms terminating in aligned inturned fingers rotatably received in bosses on said housing, means on said hood for retaining said spring frame in any position to which it is moved, whereby said spring frame assembly pivotally supports said cover on said hood for movement between a closed position in which spring frame urges said cover into sealing engagement with the end of said hood remote from said member and an open position in which said cover is out of the field of said lens, and means on said cover for preventing outward spreading movement of said spring arms to retain said spring frame assembly in engagement with the boss on said cover and to maintain said inturned fingers in said bosses on said housing.
