Abstract

Abstract A flashlight in accordance with the preferred embodiment of the invention includes a housing enclosing a battery retaining member formed with spring arms for retaining a pair of batteries in spaced-apart relationship. Further included is a light bulb having a pair of leads extending therefrom and carried at one end of the housing with the leads each connected to a battery. Adjacent the opposite end of the housing a switch wire connected to one battery extends between the battery retaining member and a flexible wall of the housing. The other end of the switch wire is located adjacent a cutout portion of the battery retaining member which exposes a surface of the other of the batteries so that when the flexible wall of the housing is pressed the other end of the switch wire contacts the other of the batteries completing a circuit between the batteries and the light bulb.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 204 words
A flashlight comprising a housing having a generally flexible side wall, a battery retaining member in said housing including resilient arm members removably retaining a pair of batteries in spaced-apart relationship, said battery retaining member being made of an insulating material, a light bulb including a pair of leads extending therefrom carried at one end of said housing, first and second conductor means carried on said battery retaining member adjacent said one end of said housing, each of said first and second conductor means being in contact with one of said leads and with one of said batteries, a third conductor means carried on said battery retaining member adjacent the other end of said housing, said third conductor means being in contact with a conductive switch wire and with one of said batteries, said switch wire extending along said battery retaining member and being adjacent said side wall of said housing, said switch wire terminating adjacent to an exposed conductive surface of the other of said batteries and being normally spaced therefrom, whereby when said side wall of said housing is pressed said switch wire contacts said exposed conductive surface of said other battery completing a circuit between said batteries and said light bulb.
Claim 2
Dependent Claim 204 words
A flashlight comprising a housing having a generally flexible side wall, a battery retaining member in said housing including resilient arm members removably retaining a pair of batteries in spaced-apart relationship, said battery retaining member being made of an insulating material, a light bulb including a pair of leads extending therefrom carried at one end of said housing, first and second conductor means carried on said battery retaining member adjacent said one end of said housing, each of said first and second conductor means being in contact with one of said leads and with one of said batteries, a third conductor means carried on said battery retaining member adjacent the other end of said housing, said third conductor means being in contact with a conductive switch wire and with one of said batteries, said switch wire extending along said battery retaining member and being adjacent said side wall of said housing, said switch wire terminating adjacent to an exposed conductive surface of the other of said batteries and being normally spaced therefrom, whereby when said side wall of said housing is pressed said switch wire contacts said exposed conductive surface of said other battery completing a circuit between said batteries and said light bulb.
Claim 3
Dependent Claim 58 words
A flashlight in accordance with claim 1 wherein said battery retaining member comprises an elongated central body portion extending generally from said one end of said housing to said other end of said housing, said body portion having a pair of said arm members extending from opposite sides thereof to form channels in which said batteries are retained.
Claim 4
Dependent Claim 25 words
A flashlight in accordance with claim 2 wherein one of said arm members includes a cutout portion providing said exposed surface of said other battery.
Claim 5
Dependent Claim 25 words
A flashlight in accordance with claim 1 wherein said battery retaining member includes a cut out portion providing said exposed surface of said other battery.
Claim 6
Dependent Claim 31 words
A flashlight in accordance with claim 1 wherein said first, second and third conductor means comprise a clip member made of conductive material and removably attached to said battery retaining member.
Claim 7
Dependent Claim 31 words
A flashlight in accordance with claim 5 wherein said clip members include a generally U-shaped member in cross-section formed with a socket in which said leads and switch wire are inserted.
Claim 8
Dependent Claim 20 words
A flashlight in accordance with claim 6 wherein said sockets are formed by a scroll extending in a transverse direction.
Claim 9
Dependent Claim 85 words
A flashlight in accordance with claim 1 wherein said battery retaining member includes a transverse end plate at each end thereof and wherein said first and second conductor means comprises generally U-shaped clip members attached to the plate at the said one end of said housing, said leads being connected to said clip member and wherein a single generally U-shaped clip member is attached to the end plate at said other end thereof and wherein said switch wire is connected to said single clip member.
Claim 10
Dependent Claim 24 words
A flashlight in accordance with claim 1 wherein said battery retaining member is formed with guide nibs between which said switch wire is located.
Claim 11
Dependent Claim 133 words
A flashlight comprising a housing having a generally flexible side wall, a battery retaining member in said housing including resilient arm members resiliently retaining a pair of batteries in spaced apart relationship, said retaining member and resilient arm members being made of an insulating material and encircling and covering a major portion of each of the batteries, a cutout portion in one arm member exposing a conductive surface of one battery, a resilient conductive switch member, socket means electrically connecting said switch member to a terminal of the other battery, said switch member extending between the housing and battery retaining member and terminating at said cutout thereby overlying and being normally spaced from the conductive surface of said one battery, a light bulb including a pair of leads electrically connected with said batteries.
Claim 12
Dependent Claim 133 words
A flashlight comprising a housing having a generally flexible side wall, a battery retaining member in said housing including resilient arm members resiliently retaining a pair of batteries in spaced apart relationship, said retaining member and resilient arm members being made of an insulating material and encircling and covering a major portion of each of the batteries, a cutout portion in one arm member exposing a conductive surface of one battery, a resilient conductive switch member, socket means electrically connecting said switch member to a terminal of the other battery, said switch member extending between the housing and battery retaining member and terminating at said cutout thereby overlying and being normally spaced from the conductive surface of said one battery, a light bulb including a pair of leads electrically connected with said batteries.
