Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
92 words
A rechargeable flashlight comprising a switch housing having an on/off switch contact therein for controlling operation of said flashlight, said housing including means for directly connecting said switch contact to the charging contact of a battery charging circuit, in which said switch housing comprises a body portion and a slide portion, said switch contact being carried by one of said switch housing portions, and in which said body and slide portions are spaced apart in parts thereof to define a channel therebetween for receiving said charging contact of said battery charging circuit.
Claim 2
Dependent Claim
92 words
A rechargeable flashlight comprising a switch housing having an on/off switch contact therein for controlling operation of said flashlight, said housing including means for directly connecting said switch contact to the charging contact of a battery charging circuit, in which said switch housing comprises a body portion and a slide portion, said switch contact being carried by one of said switch housing portions, and in which said body and slide portions are spaced apart in parts thereof to define a channel therebetween for receiving said charging contact of said battery charging circuit.
Claim 3
Dependent Claim
30 words
A flashlight according to claim 1, in combination with a holder for mounting said flashlight and carrying said charging contact in electrical-contacting position with said switch contact within said channel.
Claim 4
Dependent Claim
31 words
A flashlight/holder combination according to claim 2, in which said channel is open downwardly when said flashlight is in a vertical position, and said holder mounts said flashlight in vertical position.
Claim 5
Dependent Claim
96 words
A rechargeable flashlight comprising a switch housing having an on/off switch contact therein for controlling operation of said flashlight and connectable directly to the charging contact of a battery charging circuit, in which said switch contact is part of an electrical circuit within said flashlight to energize a lamp within said flashlight, said housing including a channel within which said switch contact is positioned, said channel having an open end thereof through which said charging contact of said battery charging circuit passes to be positioned within said channel in electrical contact-making position against said switch contact.
Claim 6
Dependent Claim
96 words
A rechargeable flashlight comprising a switch housing having an on/off switch contact therein for controlling operation of said flashlight and connectable directly to the charging contact of a battery charging circuit, in which said switch contact is part of an electrical circuit within said flashlight to energize a lamp within said flashlight, said housing including a channel within which said switch contact is positioned, said channel having an open end thereof through which said charging contact of said battery charging circuit passes to be positioned within said channel in electrical contact-making position against said switch contact.
Claim 7
Dependent Claim
92 words
A flashlight according to claim 4, in which said housing includes a second switch contact positioned within said channel and which forms with said first mentioned switch contact a pair of opposed switch contacts selectively connectable to each other to complete said circuit within said flashlight to energize said lamp, in combination with a charging circuit that includes said charging contact, said charging contact comprising a plate having electrical contact elements mounted on opposite sides thereof which are brought into electrical contact-making position each against an individual one of said switch contacts.
Claim 8
Dependent Claim
83 words
A rechargeable flashlight comprising a housing mounted on the exterior of said flashlight, said housing having an enclosed channel therein open at one end thereof, and a contact within said channel, said contact constituting one of the switch contacts of an on/off switch contained within said housing in said flashlight for controlling operation of said flashlight and connectable to a contact member of a battery charging circuit insertable into said housing through said open housing end for charging a battery within said flashlight.
Claim 9
Dependent Claim
83 words
A rechargeable flashlight comprising a housing mounted on the exterior of said flashlight, said housing having an enclosed channel therein open at one end thereof, and a contact within said channel, said contact constituting one of the switch contacts of an on/off switch contained within said housing in said flashlight for controlling operation of said flashlight and connectable to a contact member of a battery charging circuit insertable into said housing through said open housing end for charging a battery within said flashlight.
Claim 10
Dependent Claim
41 words
A flashlight according to claim 6, in combination with a holder for mounting said flashlight and carrying a contact member of a battery charging circuit in electrical-contacting position with said contact within said channel in the off position of said switch.
Claim 11
Dependent Claim
119 words
A holder for holding a flashlight for battery recharging in which the flashlight includes a contact within a channel of a housing on the exterior of said flashlihgt, and said channel is wholly enclosed except for a downwardly-opening open end thereof, comprising a tubular sleeve having a vertical axis and opposed open ends within and through which said flashlight is positioned, and an upstanding contact plate having a contact element thereon and mounted within said sleeve intermediate said open ends and in spaced relation to the inner surface of said sleeve, said contact element of said contact plate being in electrical-contacting position with said contact within said flashlight housing channel when said flashlight is positioned within said tubular sleeve.
Claim 12
Dependent Claim
119 words
A holder for holding a flashlight for battery recharging in which the flashlight includes a contact within a channel of a housing on the exterior of said flashlihgt, and said channel is wholly enclosed except for a downwardly-opening open end thereof, comprising a tubular sleeve having a vertical axis and opposed open ends within and through which said flashlight is positioned, and an upstanding contact plate having a contact element thereon and mounted within said sleeve intermediate said open ends and in spaced relation to the inner surface of said sleeve, said contact element of said contact plate being in electrical-contacting position with said contact within said flashlight housing channel when said flashlight is positioned within said tubular sleeve.
Claim 13
Dependent Claim
