US5132659A — Flashing light siren alarm

Claim 1

Independent Claim 221 words

A flashing light siren alarm which comprises: (a) a casing comprising three separable sections: an upper inverted cup-like transparent section which houses an electrical light emitting means; and inverted cup-like opaque mid-section which houses an electrical conical loud-speaker sound emitting means, the light emitting mean detachably secured to the top base of the mid-section; and an upright cup-like opaque lower section, the three sections being releasably connected together; a mounting bracket attached to the outside of the lower section; (c) an upwardly convex sound reflecting means positioned in the interior of the lower section below and in axial alignment with the electrical loud-speaker sound emitting means, and spaced from the loud-speaker to provide an even space between the periphery of the loud-speaker and the periphery of the sound reflecting means, the sound reflecting means being adapted to disperse the sound emitted by the loud-speaker sound emitting means horizontally and radially through 360° ; (d) a battery housed in the lower section adapted to power the light emitting means and the sound emitting means; and (e) a plurality of spaced sound passing ports distributed 360° around the upper region of the lower section, the ports being disposed in horizontal alignment with the even space between the periphery of the convex sound reflecting means and the periphery of the loud-speaker sound emitting means.

Claim 2

Dependent Claim 221 words

A flashing light siren alarm which comprises: (a) a casing comprising three separable sections: an upper inverted cup-like transparent section which houses an electrical light emitting means; and inverted cup-like opaque mid-section which houses an electrical conical loud-speaker sound emitting means, the light emitting mean detachably secured to the top base of the mid-section; and an upright cup-like opaque lower section, the three sections being releasably connected together; a mounting bracket attached to the outside of the lower section; (c) an upwardly convex sound reflecting means positioned in the interior of the lower section below and in axial alignment with the electrical loud-speaker sound emitting means, and spaced from the loud-speaker to provide an even space between the periphery of the loud-speaker and the periphery of the sound reflecting means, the sound reflecting means being adapted to disperse the sound emitted by the loud-speaker sound emitting means horizontally and radially through 360° ; (d) a battery housed in the lower section adapted to power the light emitting means and the sound emitting means; and (e) a plurality of spaced sound passing ports distributed 360° around the upper region of the lower section, the ports being disposed in horizontal alignment with the even space between the periphery of the convex sound reflecting means and the periphery of the loud-speaker sound emitting means.

Claim 3

Dependent Claim 45 words

An alarm as claimed in claim 1 wherein the sound reflecting means is a spherical upwardly convex surface which reflects sound emitted downwardly by the conical loud-speaker sound emitting means radially outwardly through the sound passing ports in the upper region of the lower section.

Claim 4

Dependent Claim 38 words

An alarm as claimed in claim 2 wherein the plurality of spaced sound passing ports are rectangular in shape and are spatially distributed in alignment around the circumference of the upper region of the lower-section of the casing.

Claim 5

Dependent Claim 56 words

An alarm as claimed in claim 3 wherein the loud-speaker is positioned in the interior of the open base of the mid-section and emits sound in a downwardly direction, the loud-speaker and the convex sound reflecting means being held in spaced parallel alignment with one another by the interconnection of the mid-section and the lower section.

Claim 6

Dependent Claim 37 words

An alarm as claimed in claim 1 wherein the battery is a DC electric power source which by actuation with an on-off switch means, powers an oscillator which in series drives and pulsates the light emitting means.

Claim 7

Dependent Claim 87 words

An alarm as claimed in claim 5 wherein the power source activates in series first and second oscillating means which drive the sound emitting means, the first oscillating means comprising a circuit of at least one resistor, at least one capacitor and at least one transistor, which co-operate to produce an oscillating signal, and the second oscillating means comprising a circuit of at least one resistor, at least one capacitor and at least one transistor which co-operate to produce an output which drives the sound emitting means.

Claim 8

Dependent Claim 47 words

An alarm as claimed in claim 6 wherein the output of the power source is passed through a transformer, at least one resistor, and at least one transistor, and a capacitor which builds up voltage to a level where it discharges and activates the light emitting means.

Claim 9

Dependent Claim 29 words

An alarm as claimed in claim 7 wherein the output of the capacitor is connected to a pair of trigger electrodes, which cause the light emitting means to flash.
