Definitions

  • This invention relates generally to a combination smoke and carbon monoxide detector. More particularly, the invention relates to a smoke and carbon monoxide detector that is self-powered and rechargeable.
  • Smoke detectors are well known in the prior art. Two examples of modern smoke alarms are provided in U.S. Patent No. 4,827,244 to Bellavia and U.S. Patent No. 4, 1 66,960 to Meili. Typically, smoke detectors provide an audible alarm to alert nearby people of a fire. Smoke detectors may also include lights to help direct persons toward exits during the course of a fire.
  • U.S. Patent No. 4,763,1 1 5 to Cota further discloses the use of a redundant circuit that activates by a central audible alarm to trigger a smoke alarm and flashing circuits.
  • U.S. Patent No. 5,572,1 83 to Sweeney discloses a device that sweeps a laser beam across a plurality of mirrors. Each mirror directs the laser beam onto the floor at a different location. The path of the laser beams move toward a building exit.
  • U.S. Patent No. 5,140,301 to Watanabe further discloses a centrally controlled smoke detector network that generates a laser, which is guided and oscillated by a controlling mirror, to direct persons to a building exit point.
  • U.S. Patent No. 6,1 81 ,251 to Kelly also discloses a smoke detector that includes a pulse laser in a single housing with a detection means.
  • the pulse laser is mounted on a laser point means which allows for pointing the laser in multiple directions.
  • a self-powered rechargeable smoke and carbon monoxide detector is needed.
  • a detector should include a base unit that connects directly into a 1 10-volt light bulb socket thereby requiring no battery maintenance and no need for drilling holes or otherwise using hand tools to install the detector.
  • the smoke and carbon monoxide detector should include a socket for reception of a 1 10-volt light bulb, thereby not precluding use of the 1 10-volt socket as a light source.
  • the smoke and carbon monoxide detector should also include a means for quickly and easily silencing the alarm without actually touching the detector.
  • the present invention relates to a system for detecting smoke and/or carbon monoxide comprising a base unit including a smoke detector and a carbon monoxide detector formed therein.
  • the base is self-powered and rechargeable via a 1 1 0-volt socket formed at one end.

  • the present invention further includes an alarm associated with the smoke detector and the carbon monoxide detector. The alarm is tested by flipping a light switch on/off in predetermined successive repetitions. Furthermore, the smoke and carbon monoxide detector alarm is deactivated by flipping the same light switch on/off in a different predetermined set of repetitions. The light switch is electrically wired to the 1 10-volt light bulb socket.
  • the light switch regulates the flow of electricity to the socket. Without the detector, the light switch functions as a standard on/off light switch.
  • the smoke and carbon monoxide detector of the present invention also includes a variety of warning indicators including a speaker that issues an audible alarm or pre-recorded message. Additionally, a power indicator LED, a smoke detector indicator LED, and a carbon monoxide detector indicator LED provide external visual notification that the smoke and carbon monoxide detector is properly powered and functioning.
  • FIGURE 1 is a perspective view of a smoke and carbon monoxide detector on the present invention, incorporating a 1 1 O-volt light bulb;
  • FIGURE 2 is a side view of the detector of FIG. 1 ;
  • FIGURE 3 is an alternative embodiment of FIG. 2, excluding the 1 10- volt light bulb;
  • FIGURE 4 is a schematic view of the present invention illustrating the electrical connections

  • the light bulb socket connector 1 as shown in FIGS. 1 -3, fits directly into a standard fixture 1 5 (FIG. 4).
  • Placing the smoke and carbon monoxide detector 1 0 within an existing light fixture via the light bulb socket connector 14 eliminates any unsightly smoke or carbon monoxide detectors, eliminates any issues with dead batteries, and eliminates any need for a do-it-yourself installation of a new smoke detector or carbon monoxide detector.
  • the smoke and carbon monoxide detector 10 of the present invention utilizes a power source 1 6 electrically connected to the light bulb socket connector 1 4 via an electrical wire 1 8 and the light fixture 1 5.
  • the power source 1 6 provides the requisite electricity to power and recharge a battery 20 located internal to an outer case 22 of the detector 10.
  • the battery 20 is preferably a rechargeable Lithium-ion battery.
  • the battery 20 could also incorporate an additional standard 9-volt battery therein.
  • the smoke and carbon monoxide detector 1 0 incorporates a permanently mounted rechargeable battery and a removable 9-volt battery within the outer case 22.
  • the rechargeable battery be non-accessible within the outer case 22 absent destruction of the smoke and carbon monoxide detector 10.
  • the smoke and carbon monoxide detector 1 0 would still be powered by the rechargeable battery.
  • the smoke and carbon monoxide detector 10 has a built-in charger to power the rechargeable battery when interconnected with an alternating current (AC) or direct current (DC) power source. If the detector 1 0 is not hard-wired, the rechargeable battery powers the internal circuitry when the traditional 9-volt battery is removed.
  • AC alternating current
  • DC direct current
  • the smoke and carbon monoxide detector 1 0 be placed in a light fixture 1 5 that is switched on for a total of one hour per week.
  • the internal battery 20 of the smoke and carbon monoxide detector 10 continues to power the detector 10. Accordingly, the integral battery 20 of the smoke and carbon monoxide detector 10 is recharged and self-powered when the power source 1 6 supplies electricity thereto.
  • the smoke and carbon monoxide detector 1 0 includes the outer case 22 that houses the battery 20, a smoke detector circuitry 24, and a carbon monoxide detector circuitry 26, as referenced generally in FIG. 4.
  • the battery 20 is electrically connected to the electrical wire 1 8 that supplies electricity to the smoke and carbon monoxide detector 10 from the power source 1 6.
  • the outer case 22 is made from a material that is moisture and corrosion resistant.
  • the smoke detector circuitry 24 may consist of a photoelectric detector, ionization detector or a combination of detectors known in the art. Additionally, the circuitry of the battery 20, the smoke detector circuitry 24, and the carbon monoxide detector circuitry 26 are also moisture and corrosion resistant through the application of a spray-on silicon.
  • the spray-on silicon protects the circuits and other electrical components of the detector 1 0 from corrosion or degradation due to moisture in the air. This improved moisture and corrosion resistance increases the effective lifespan of the smoke and carbon monoxide detector 1 0.
  • a smoke and carbon monoxide detector 10 may be safely placed in areas of high moisture such as the garage, workshop, laundry room, or furnace area.
  • the smoke and carbon monoxide detector 1 0 of the present invention is tested via a power switch 28.
  • the smoke detector circuitry 24 and the carbon monoxide detector circuitry 26 are configured such that quick and repetitious flicks of the power switch 28 from an off position to an on position, or vice versa, places the smoke and carbon monoxide detector 10 into a self-test cycle after a short delay.
  • any combination of flicks may be used to initiate the self-test cycle. Users are not required to actually touch the smoke and carbon monoxide detector 1 0 to test the alarm. Unlike other smoke detectors or carbon monoxide detectors, users must push a button, flip a switch, or activate another mechanism mounted directly to the smoke detector or the carbon monoxide detector. In these devices, users must be able to readily reach the actual unit. This procedure is particularly laborious if the smoke detector or carbon monoxide detector is mounted to a high or cathedral ceiling. Users risk injury by falling when attempting to reach smoke detectors or carbon monoxide detectors several feet in the air.
  • the power switch 28 provides a convenient and simple mechanism to test the smoke and carbon monoxide detector 1 0. Typically, the power switch 28 is easy to reach by almost any individual at ground level. No ladders or other lift devices are needed to gain access to the detector 10.
  • deactivating a false alarm is accomplished in a manner similar to initiating the self-test cycle previously described.
  • users need only repetitiously switch the power switch 28 of/off, or vice versa, in rapid succession for a predetermined number of flicks.
  • users must repeat the on/off motion twice.
  • the smoke and carbon monoxide detector 10 silences and resets automatically.
  • users are not required to deactivate the alarm by physically touching or engaging the actual detector 1 0.
  • the present invention should not be limited with respect to the process of testing the smoke and carbon monoxide detector 1 0 or disabling a false alarm.
  • the detector 10 of the present invention also incorporates a light socket 30.
  • FIG. 5, illustrates the light socket 30 incorporated into the underside of the smoke and carbon monoxide detector 10.
  • the light socket 30 is generally formed opposite the light bulb socket connector 1 4.
  • the light bulb socket 30 is configured to threadingly receive a 1 1 0-volt light bulb.
  • a plurality of apertures 32, 33 are formed in the outer case 22 of the smoke and carbon monoxide detector 1 0.
  • the apertures 32, 33 provide an entrance for potential smoke or carbon monoxide hazards. Additionally, the apertures 32, 33 function to radiate sound from an alarm located within the interior of the outer case 22, during an emergency.
  • Embedded within the smoke detector circuitry 24 and the carbon monoxide detector circuitry 26 are speakers that issue an audible alarm when either the smoke detector circuitry 24 or the carbon monoxide detector circuitry 26 detects smoke or carbon monoxide, respectively.
  • the smoke and carbon monoxide detector 10 may include a power indicator LED 34, a smoke indicator LED 36 and a carbon monoxide indicator LED 38 that flash or light up in the event of a power failure, fire, or carbon monoxide leak.
  • the power indicator LED 34, the smoke indicator LED 36, and the carbon monoxide indicator LED 38 may all protrude from the outer case 22 as shown in FIG. 1 . Alternatively, the LEDs 34, 36, 38 may remain flush with the outer case 22. The important aspect is that the LEDs 34, 36, 38 are visible.
  • the smoke and carbon monoxide detector 10 fits into any one of a number of the light fixtures 1 5.
  • the light bulb socket connection threadingly engages the light fixture 1 5.

Hence, additional tools, time, and costs associated with mounting an additional smoke detector or carbon monoxide detector is alleviated.
  • Utilizing the light fixture 1 5 as a lighting source is not lost from insertion of the detector 1 0 within the light fixture 1 5.
  • the corresponding light socket 30 is capable of receiving the light bulb 1 2 so that the light fixture 1 5 may still be used as a light source.
  • the light bulb 1 2 is powered from the electrical source 1 6 via the electrical wire 1 8, not the battery 20. Therefore, when the power switch 28 cuts off the electricity to the light fixture 1 5 from the power source 1 6, any light bulb 1 2 inserted within the light socket 30 will turn off.
  • the smoke and carbon monoxide detector 1 0 is aesthetically pleasing as an additional wall mounted power source or additional ceiling mounted power source is not required for installation.
  • the present invention is also intended to be installed with baton and pendent type lighting fixtures that hang from the ceiling.
  • installation within lamp shades that allow the flow of air in, around, and through the apertures 32, 33 in the outer case 22 of the smoke and carbon monoxide detector 1 0 is also contemplated. Lamp shades that are open at both ends are particularly preferred.
  • Any one of a number of the 1 1 0-volt light bulbs 1 2 may also be used with the smoke and carbon monoxide detector 10.
  • conventional light bulbs that have a maximum rating of 75 watts and long life (PL Tube) type bulbs with a similar 75 watt rating are preferred.
