Abstract
Abstract A multi-function lighted walking cane which may be used in the dark as a cane for lighting the user's walkway and may also be used as a beacon to show the user's position to others. The light-emitting portion of this invention is housed adjacent and within a translucent or transparent lens positioned near the lower end of the cane. It may optionally have a raised lens shape which enhances the light-dispersing characteristics of the cane. The lens is positioned so that light is cast forward of the user along the ground. A plurality of small apertures may also be provided in the hollow cane adjacent the light source around the remaining surface juxtaposed to the lens to provide the beacon light function. This lower portion of the cane, housing the light source near its lower end, contains the battery and the power supply. The length of the cane may is made adjustable. The cane has a connector for attaching a battery charger to recharge batteries in the cane.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
165 words
A lighted walking cane which comprises: an upper tubular part having a handle at its upper end and an open ended lower end; a lower tubular part telescopingly received in said upper part; a battery compartment in said lower part for containing a plurality of axially disposed, series connected batteries in the battery compartment; having an upper and a lower battery terminal for producing a battery voltage; a voltage converter in said lower part having input terminals for receiving and converting the battery voltage to a high secondary A.C. voltage; a fluorescent tube disposed axially in the lower end of said lower tubular part having end terminals connected to said high A.C. voltage for firing and maintaining said fluorescent tube in lighted condition, said lower tubular part having apertures in its wall for admitting light to the outside; electrical circuit means for interconnecting said battery compartment, said converter and said fluorescent tube; and locking means for adjustably locking together said upper and lower tubular parts.
Claim 2
Dependent Claim
165 words
A lighted walking cane which comprises: an upper tubular part having a handle at its upper end and an open ended lower end; a lower tubular part telescopingly received in said upper part; a battery compartment in said lower part for containing a plurality of axially disposed, series connected batteries in the battery compartment; having an upper and a lower battery terminal for producing a battery voltage; a voltage converter in said lower part having input terminals for receiving and converting the battery voltage to a high secondary A.C. voltage; a fluorescent tube disposed axially in the lower end of said lower tubular part having end terminals connected to said high A.C. voltage for firing and maintaining said fluorescent tube in lighted condition, said lower tubular part having apertures in its wall for admitting light to the outside; electrical circuit means for interconnecting said battery compartment, said converter and said fluorescent tube; and locking means for adjustably locking together said upper and lower tubular parts.
Claim 3
Dependent Claim
39 words
Lighted walking cane according to claim 1 wherein said electrical circuit means further comprises: an on/off switch disposed proximal to said handle for completing and deactivating said electrical circuit means for respectively turning said fluorescent tube on and off.
Claim 4
Dependent Claim
78 words
Lighted walking cane according to claim 1 wherein said locking means further comprise: a plurality of axially spaced apart adjustment holes in the wall of the upper tubular part; a matching hole in the wall of the lower tubular part matchingly alignable with any one of said adjustment holes; a radially outward projecting locking button slidably receivable in said matching hole and in any of said adjustment holes for locking rigidly together said upper and lower tubular part.
Claim 5
Dependent Claim
33 words
Lighted walking cane according to claim 1 wherein said voltage converter comprises: a transistor oscillator; a transformer being part of said oscillator, said transformer comprising a core of iron powder having high permeability.
