Safety-enhancing walking stick

Claim 2

A safety-enhancing walking stick to provide a flashing light warning signal, comprising: a tubular casing having a least one portion which is translucent; a light source for providing flashes of light, disposed within said tubular casing adjacent to said portion of said tubular casing which is translucent; electronic circuit means disposed within said tubular casing, and coupled to said light source for periodically actuating said light source to provide said flashes of light; a battery disposed within said tubular casing for supplying power to said electronic circuit means; switch means for selectively connecting said battery to said electronic circuit means; and means for detecting the level of ambient light, said detecting means being coupled to said electronic circuit means for controlling said flashes of light produced by said light source.

Claim 3

A safety-enhancing walking stick according to claim 1, wherein said means for detecting the level of ambient light comprises a photocell disposed within said tubular casing.

Claim 4

A safety-enhancing walking stick according to claim 1, wherein said tubular casing comprises a translucent material throughout.

Claim 5

A safety-enhancing walking stick according to claim 3, wherein said translucent material comprises glass fibre-reinforced plastic.

Claim 6

A safety-enhancing walking stick according to claim 1, wherein at least a portion of said tubular casing comprises a metallic material.

Claim 7

A safety-enhancing walking stick according to claim 5, wherein said metallic material comprises an aluminum alloy.

Claim 8

A safety-enhancing walking stick according to claim 1, wherein said light source comprises a xenon flash tube.

Claim 9

A safety-enhancing walking stick according to claim 7, wherein said electronic circuit means comprises a voltage step-up coil connected to electrodes of said xenon flash tube and a silicon controlled rectifier coupled to said voltage step-up coil for triggering said xenon flash tube.

Claim 10

A safety-enhancing walking stick according to claim 1, wherein said switch means comprises a knob disposed at one end of said tubular casing, a portion of said knob being contained within said tubular casing and rotatable therein, and wherein contact portions are provided on said portion of said knob contained within said tubular casing for connecting said battery to said electronic circuit means when said knob is rotated into a predetermined position.

Claim 11

A safety-enhancing walking stick according to claim 1, wherein said at least one portion of said tubular casing which is translucent is tinted in a suitable color.

Claim 12

A safety-enhancing walking stick to provide a flashing light warning signal, comprising: a tubular casing having at least one portion which is translucent; a light source for providing flashes of light, disposed within said tubular casing adjacent to said portion of said tubular casing which is translucent; electronic circuit means disposed within said tubular casing, and coupled to said light source for periodically actuating said light source to provide said flashes of light; and a battery disposed within said tubular casing for supplying power to said electronic circuit means; said light source comprising a xenon flash tube, and said electronic circuit means comprising a voltage step-up coil connected to electrodes of said xenon flash tube and a silicon controlled rectifier coupled to said voltage step-up coil for triggering said xenon flash tube.

Claim 13

A safety-enhancing walking stick to provide a flashing light warning signal, comprising: a tubular casing having at least one portion which is translucent; a light source for providing flashes of light, disposed within said tubular casing adjacent to said portion of said tubular casing which is translucent; electronic circuit means disposed within said tubular casing, and coupled to said light source for periodically actuating said light source to provide said flashes of light; and a battery disposed within said tubular casing for supplying power to said electronic circuit means; said light source comprising a xenon flash tube, and said electronic circuit means comprising a voltage step-up coil connected to electrodes of said xenon flash tube and a silicon controlled rectifier coupled to said voltage step-up coil for triggering said xenon flash tube.
