Abstract

Abstract A flashlight has a spherical end portion including a spherically curved transparent lens. A frusto conical hood formed from a resilient rubber material is received in surrounding relation on the spherical portion and includes a socket forming a ball and socket pivotal connection with the spherical portion. The hood forms a glare shield around the flashlight lens and is designed for abutment with a window pane. Relative pivotal movement of the body portion of the flashlight with respect to the hood allows an individual to direct a light beam in a variety of directions through a window pane without being subject to a reflective glare.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 288 words
A flashlight with a pivotal hood, comprising: an elongated hollow cylindrical body member; a generally spherical portion on one end of said body member; an aperture formed through a distal end of said spherical portion; an internal thread formed in said spherical portion, adjacent said aperture; an externally threaded connector ring in threaded engagement within said aperture; a lens having a spherically curved surface secured over said aperture by said connector ring, said lens having a curvature matching said spherical portion; a metallic reflector centrally supported in said spherical portion by said connector ring; an electric lamp mounted in a socket on said reflector; a plurality of batteries in said hollow body member, an inner one of said batteries having a terminal in abutment with a contact on said socket; a switch mounted exteriorly on said body member, said switch connected to a slidable contact; said slidable contact selectively engageable with an inner surface of said reflector, said reflector electrically connected to said lamp; a threaded end cap on an end of said body member opposite said spherical portion; a frusto conical hood formed from a rubber material and received in surrounding relation on said spherical portion; said hood having a narrow end forming a socket in engagement with said spherical portion, forming a ball and socket pivotal connection; an internal resilient ring on said hood, surrounding said spherical portion to restrain relative axial movement between said spherical portion and said hood; and said hood having a wide end terminating in a circular rim adapted for abutment with a window pane, whereby an individual may pivot said body member and spherical portion relative to said hood to direct a light beam in various directions through a window pane.
Claim 2
Dependent Claim 288 words
A flashlight with a pivotal hood, comprising: an elongated hollow cylindrical body member; a generally spherical portion on one end of said body member; an aperture formed through a distal end of said spherical portion; an internal thread formed in said spherical portion, adjacent said aperture; an externally threaded connector ring in threaded engagement within said aperture; a lens having a spherically curved surface secured over said aperture by said connector ring, said lens having a curvature matching said spherical portion; a metallic reflector centrally supported in said spherical portion by said connector ring; an electric lamp mounted in a socket on said reflector; a plurality of batteries in said hollow body member, an inner one of said batteries having a terminal in abutment with a contact on said socket; a switch mounted exteriorly on said body member, said switch connected to a slidable contact; said slidable contact selectively engageable with an inner surface of said reflector, said reflector electrically connected to said lamp; a threaded end cap on an end of said body member opposite said spherical portion; a frusto conical hood formed from a rubber material and received in surrounding relation on said spherical portion; said hood having a narrow end forming a socket in engagement with said spherical portion, forming a ball and socket pivotal connection; an internal resilient ring on said hood, surrounding said spherical portion to restrain relative axial movement between said spherical portion and said hood; and said hood having a wide end terminating in a circular rim adapted for abutment with a window pane, whereby an individual may pivot said body member and spherical portion relative to said hood to direct a light beam in various directions through a window pane.
Claim 3
Dependent Claim 282 words
A flashlight with a pivotal hood, comprising: an elongated hollow body member; a generally spherical portion on one end of said body member; an aperture formed through a distal end of said spherical portion; an internal thread formed in said spherical portion, adjacent said aperture; an externally threaded connector ring in threaded engagement within said aperture; a lens having a spherically curved surface secured over said aperture by said connector ring, said lens having a curvature matching said spherical portion; a metallic reflector centrally supported in said spherical portion by said connector ring; an electric lamp mounted in a socket on said reflector; an electric power source in said hollow body member, a first terminal of said electric power source connected with a contact on said socket; a switch mounted exteriorly on said body member, said switch connected to a slidable contact; said slidable contact electrically connected to a second terminal of said electric power source and selectively engageable with an inner surface of said reflector, said reflector electrically connected to said lamp; a frusto conical hood formed from a rubber material and received in surrounding relation on said spherical portion; said hood having a narrow end forming a socket in engagement with said spherical portion, forming a ball and socket pivotal connection; an internal resilient ring on said hood, surrounding said spherical portion to restrain relative axial movement between said spherical portion and said hood; and said hood having a wide end terminating in a circular rim adapted for abutment with a window pane, whereby an individual may pivot said body member and spherical portion relative to said hood to direct a light beam in various directions through a window pane.
Claim 4
Dependent Claim 282 words
A flashlight with a pivotal hood, comprising: an elongated hollow body member; a generally spherical portion on one end of said body member; an aperture formed through a distal end of said spherical portion; an internal thread formed in said spherical portion, adjacent said aperture; an externally threaded connector ring in threaded engagement within said aperture; a lens having a spherically curved surface secured over said aperture by said connector ring, said lens having a curvature matching said spherical portion; a metallic reflector centrally supported in said spherical portion by said connector ring; an electric lamp mounted in a socket on said reflector; an electric power source in said hollow body member, a first terminal of said electric power source connected with a contact on said socket; a switch mounted exteriorly on said body member, said switch connected to a slidable contact; said slidable contact electrically connected to a second terminal of said electric power source and selectively engageable with an inner surface of said reflector, said reflector electrically connected to said lamp; a frusto conical hood formed from a rubber material and received in surrounding relation on said spherical portion; said hood having a narrow end forming a socket in engagement with said spherical portion, forming a ball and socket pivotal connection; an internal resilient ring on said hood, surrounding said spherical portion to restrain relative axial movement between said spherical portion and said hood; and said hood having a wide end terminating in a circular rim adapted for abutment with a window pane, whereby an individual may pivot said body member and spherical portion relative to said hood to direct a light beam in various directions through a window pane.
