Abstract

Abstract A portable hand held distress signal device having a casing member for receiving dry cell batteries with the casing having positive and negative terminals and an ON-OFF switch connected in series therewith, a dome member of generally red plastic transparent material having an end portion for receiving a signal member and an enlarged portion for receiving a control member and an engaging portion for connecting securably with a mating engaging portion of the casing member, the control member including a frame member having respective current terminals for engaging with the terminals of the casing member, a buzzer and motor in the control member connected in circuit with the terminals of the signal member, a shaft of the motor driving reduction gears which in turn rotate a metal shaft extending within the dome member, a reflector and bulb holder supported at the distal end of the metal shaft and for supplying current from one of the terminals thereto, a metal disk having a central opening for passing the metal shaft therethrough and being mounted on the frame connected to the other of the terminals, and a trolley mounted on the reflector and bulb means extending in contact with the metal disk for completing the circuit of the one terminal to the other terminal. The device is further summarized as a portable hand-held visually and audibly detectable distress signal device, particularly suited for hikers, campers, mountain climbers, senior citizens, school children, broken down RV's, planes, cars, boats, life rafts, motorcycles, workers in mines, tunnels, and the like, for seeking and attracting the attention of others when in a troubled situation.

Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 248 words
A portable distress sigal device comprising casing means for receiving current storage means with positive and negative terminals and having an ON-OFF switch connected in series therewith, dome member of generally transparent material having an end portion for receiving a signal means and an enlarged portion for receiving control means and an engaging portion distal to the end portion for connecting securably with a mating engaging portion of the casing means, the control means including frame means having respective current terminals for engaging with the terminals of the casing means, buzzer and motor means in the control means connected in parallel circuit relation with the terminals of the frame means in the dome member, a shaft of the motor means driving reduction gears one of which in turn is connected to a proximate end of a support metal shaft extending within the dome member and drives the shaft in rotation, means supporting a reflector and bulb holder at a distal end of the support metal shaft and for supplying current thereto from one of the terminals of the frame means, a metal disk having a central opening for passing the support metal shaft therethrough and the metal disk being mounted on the frame means connected to the other of the terminals of the frame means, and means mounted on the reflector and bulb means extending in trolley contact with the metal disk for completing the circuit of the one terminal to the other terminal of the frame means.
Claim 2
Dependent Claim 248 words
A portable distress sigal device comprising casing means for receiving current storage means with positive and negative terminals and having an ON-OFF switch connected in series therewith, dome member of generally transparent material having an end portion for receiving a signal means and an enlarged portion for receiving control means and an engaging portion distal to the end portion for connecting securably with a mating engaging portion of the casing means, the control means including frame means having respective current terminals for engaging with the terminals of the casing means, buzzer and motor means in the control means connected in parallel circuit relation with the terminals of the frame means in the dome member, a shaft of the motor means driving reduction gears one of which in turn is connected to a proximate end of a support metal shaft extending within the dome member and drives the shaft in rotation, means supporting a reflector and bulb holder at a distal end of the support metal shaft and for supplying current thereto from one of the terminals of the frame means, a metal disk having a central opening for passing the support metal shaft therethrough and the metal disk being mounted on the frame means connected to the other of the terminals of the frame means, and means mounted on the reflector and bulb means extending in trolley contact with the metal disk for completing the circuit of the one terminal to the other terminal of the frame means.
