A window mounted, 110 volt A/C car warmer and window defroster.

Description

-2~2192~

Specification There are a number of automobile window defrosters on the market all of which are generally unacceptable since they take too long to do their job.
Usually when someone is trying ~o remove frost from their automobile windshield they are Ieaving for work and time is thereI`ore very much of the essence. The reasoll why so mally of these devices fail is because they are madeto operate on the vehicles own twelve volt power sysl-em, which means that the force of warm air which they produce is Iess than adequate to do the job of clearing the windsllield alld since waiting any length of time is out of the question the device becomes unusable. Another drawback of these devices is that they drain precious power ~rom the automobile baltery which is vitally needed for starting the ear in cold weather. l'lug in 110 volt window defr-osters and car heaters have not appeared on the market because of the various problems involved trying ~o run a statioll~ry land based 1 10 volt system lo service the interior of a motor vehicle.
My invention overcomes all of these problems and provides a much needed service for all motor vehicle owners in that it is able to el`fectively defrost all of th~ whl(lows hl :1 nloler vehicle and al the same time warm the interior using regular 1 10 volt A/C pOwer. It eliminates the necessity of having to clean the windows saving the driver precious time and providing a greater margin of driving safèty by having all of the windows completely frost free.
My defroster Ullit is made to be mounted on a side or rear window of a vehicle and is held in place by the window itself. The device is simply placed on the top edge of either front or rear side window and by raising the window to the closed pOSitiOIl the de~oster is clamped firmly in place and may be left there for the duration of the winter season. Power is supplied by an ordinary 110 volt extension cord which is then plugged into the device on the outside of the window The essence of this invention lies in the manner in which 110 volt power is supplied to the interior of the motor vehicle without the use of wires and without violating in any way the integrity of the motor vehicle's exterior envelope.

Two manifestations of my invention are shown in the drawings, where Fig. 1 shows a perspective of a device looking at it from inside the vehicle wilh the device mounted on tlle top edge of an open side window,Fig.2 shows a section A-A through the device, Fi~. 3 shows a 212i92~

delail of l ig 2 where lhe device passes over the top of the window, and l i~. 4 shows a di~rerent manirestation Ormy invention, one which would allow the heaLer Ullit on tl~e inside ol`lhe vellicle lo be detached or unplu~gcd .
In whictl (a) is lhe body ol` tlle heater cont~hling lhe motor,Làn, and heating element. (b) is Ihe top edge of the side or rear window of a motor vehicle, (c) is the extcnsion cord supplyill~ standard 110 volt power to the unit, and (d) and (r) shows where the extension cord will plug into which is on the outside of the vehicle's window. (e) is a steel spring which holds the device rlrnlly againsl the window (1~ showing the conductor route and (g) showing the insulatiny, m~terial and (h) ~howin~, the top of the window. (i) shows the motorwhich is fastened to the body of the unit (a) at ~j) and which drives the fàn (k) air is taken in through the vents (I) and passes over the heating element (m) and is directed by the cowling (n) into the interior of the vehicle. (o) is a thermostat which acts to turn the heater and fan of r as soon as the interior of the vehicle reaches a cerLain temE~erature, that is,normal room temperature warrn enough to keep all of the vehicle's windows l`ree of frosl. (p) shows where an exlension cord or device havin~ a plug-in cord might be plugged into the device on the inside of the vehicle. (q) shows a cover which would be closed over the e~teriorplug-in tines (t) when thc vehicle was travclling or the dcvice was not in use to ~resent a more streamlhled appearance and prevent wind noise. (s) shows a slot provided in the device to a(;commodate lhe top edge of the motor vehicle's window.
'I'he body ol` the device collld bc made of bakelite or some type of heat resislant plas~ic.

Claims

Claims (1) A 110 volt electrical connector either separate, or incorporated into the body of an electrical device, such as a fan, heater, or dryer, made to fit over the top or side edge of a window, such as in a motor vehicle, and which will allow such window to be closed.

(2) A 110 volt electrical connector as in claim (1) having a standard male plug-in recepticle appearing on the outside of a window, say on a motor vehicle,when it is installed on a window and the window is closed.

(3) A 110 volt window mounted electrical connector having a standard 110 volt male plug-in recepticle appearing on the one side or a window, when mounted on a window, and a 110 volt female plug-in recepticle appearing on the other or opposite side of a window.

(4) A 110 volt window mounted electrical connector or device incorporating a thermostat.

(5) A 110 volt window mounted electrical device or connector having a metal spring or suction cup to hold it firmly against a window.
