Abstract
Abstract A flashlight device of the type for use with one or more battery cells including a main body member having a switch actuatable light assembly. Two or more barrel members having threaded connections are interchangeably connectable with the main body member for increasing the battery cell capacity and length of the device, and an end cap assembly including a detachable fastener element for mounting a hand carrying member is threadable interchangeable for use with the main body or barrel members during normal use thereof. The end cap assembly has a compartment-like recess therein in which the fastener element may be selectively disposed.

Claim 3
Dependent Claim
136 words
A flashlight device in accordance with claim 1, wherein said body member further comprises an integral head section disposed adjacent the front end thereof, said head section comprising, an integral forward portion having an annular configuration of generally uniform diameter, and an integral rear portion having an annular configuration which tapers inwardly and rearwardly in a direction away from said forward portion; and an integral flange section having an annular configuration and extending integrally forwardly from said forward portion, said flange section being provided with head thread means, and said device further including a face cap member having cap thread means and being disposed adjacent said flange section and threadably connected to said cap thread means on said flange section for maintaining the disposition of said light assembly at the front end of said body member.
Claim 4
Dependent Claim
78 words
A flashlight device in accordance with claim 2, wherein said light assembly includes a tapered reflector member disposed within said body member and projecting forwardly of said flange section, said face cap member disposed in encompassing relation around said reflector member and restraining the same against axial movement with respect to the longitudinal central axis of said device, and said face cap including an annular outwardly flared surface extending generally coincidently with respect to said tapered reflector member.
Claim 5
Dependent Claim
36 words
A flashlight device in accordance with claim 2, wherein said cap face member includes a peripheral knurled surface portion, said cap face member having generally the same diameter as the forward portion of said head section.
Claim 6
Dependent Claim
15 words
A flashlight device in accordance with claim 1, wherein said carrying element comprises a thong.
Claim 7
Dependent Claim
42 words
A flashlight device in accordance with claim 1, wherein said fastener element includes an annular collar portion between its ends, and said transversely apertured end comprising an elongated stub shank extending outwardly from said collar portion having a transverse aperture extending therethrough.
Claim 8
Dependent Claim
212 words
A flashlight device in accordance with claim 1, wherein said body member includes a first barrel member made integral therewith, a second barrel member for detachable connection to the first barrel member, said first barrel member including an elongated cylindrical passageway for receiving an electrical battery cell therein, said first barrel member including said first thread means made integral therewith for detachably connecting said first barrel member with said second barrel member, said second barrel member having an elongated, generally cylindrical configuration with an elongated cylindrical passageway for receiving at least one additional electrical battery cell therein and also including integral second complementary thread means at one end for thread connection with said first connection thread means on said first barrel member, said second barrel member including integral second thread means for detachably connecting said second barrel member with said rear cap assembly, and said complementary thread means being threadably connectable to said first thread means of said first barrel member to provide a first, predetermined electrical battery cell capacity and threadably connectable to said second thread means of said second barrel member when said second barrel member is connected to said first barrel member to provide a second, predetermined electrical battery cell capacity which is greater than said first matching capacity.
