Abstract
A lens cover device for a camera lens, particularly suited for use with a telephoto lens and hood assembly, comprises a disk-like body member having a plurality of retention members. The retention members provide friction within the filter-thread region of the camera lens. A large handle attached to one face of the cover device enables a photographer to easily cover or uncover the lens whether the lens and hood are in the shooting position or the stored position.
Claims9
A lens cap device for a camera lens, the device comprising:
- a disk-like body;
- a handle member disposed on a first face of the disk-like body;
- a plurality of friction-enhancing retention members protruding from a second face of the disk-like body, wherein the second face is disposed opposite the first face;
- and wherein any at least one of the plurality of retention members further comprises a generally cylindrical strut having a channel receiving an annular ring member, the strut coupled to the second face at one end and terminating in a head at an opposite end, the head retaining the annual ring member.
A lens cap device for a lens having a barrel with an interior wall portion adjacent to a front face of the lens, the device comprising:
- a disk-like body;
- a handle member disposed on a first face of the disk-like body;
- and
- a shoulder arranged adjacent to a second face of the disk-like body wherein the second face is arranged opposite from the first face;
- at least three retention members disposed on the second face wherein at least one retention member comprises a strut protruding generally perpendicular from the second face,
- the strut retaining an annular ring member, and
- the ring member being disposed on the strut so that a portion of the ring member overlaps a corresponding portion of the shoulder, but does not extend further than a circumference defined by an outer edge of the disk-like body whereby the cooperation of the at least three retention members enables a friction fit of the device with the interior wall portion provided by the camera lens.
