Description

~3~
This application relates to apparatus for automatically connecting a motor vehicle block heater to an electrical outlet.

BACRGROUND OF TOE INVENTION

In cold climates such as those of the Northern United States and Canada, it is customary for vehicle owners to utilize electric heaters during cold winter months to ease problems in starting vehicle engines. These heaters take a variety of configurations but are most commonly of the type identified as block heaters, in that they are inserted into coolant circulation spaces ln the engine block. Other types of heaters include electrically heated blankets for vehicle batteries and heaters and fans for the interior of the vehicle. Normally electrical input to these heaters is via wires which are provided at the end remote from the heater with a conventional plug. An extension cord is then run from the plug to an electrical outlet.
In some locations, such as at apartment building parking lots, electrical outlets are provided adjacent each parking space, so that a relatively short extension cord may be utilized. I,onger such cords are normally utilized for this purpose at single family and the Mike dwelling units.
The use of these devices is very inconvenient in the sub-freezing temperatures in which they are used. As well, they can be dangerous.
The inconvenience usually involves removing ones .

handwear in order to facilitate the manipulation required to attach the extension cord to the heater plug, thus exposing the bare hands to the sub-freezing temperatures. As well, the heater plug is frequently wet from melting snow, splashing from salted streets and the like. The wet plug can and does lead to electric shocks and to short circuits, the latter causing blown fuses or tripped circuit brea]cers.
Finally, it is often difficult -to ensure that the heater is in fact receiving power and operating properly.
Against this background the present invention provides an apparatus fox automatically connecting the block heater plug to an electrical outlet.

PRIOR ART

The applicant is unaware of any prior art having application to this area. To the best of applicant's knowledge the extension cord procedure is currently universally utilized.

BRIEF SUMMARY OF TOE INVENTION

An apparatus has now heen provided which permits the operator of a vehicle to drive the vehicle into a position in which the block heater power cord automatically engages an electrical outlet. Thus, the invention provides an apparatus for facilitating connection between a source of electrical energy and an electrically powered device comprising a receptacle connected to a source of electrical energy, the receptacle including therein electrical receptacle contacts; a probe adapted to be connected to an electrically powered device and to be inserted into the receptacle, the probe including thereon electrical probe contacts adapted Jo electrically connect with the receptacle contacts when the probe is inserted into the receptacle; and guide means associated with the receptacle for aligning the probe with the receptacle.

DETAILED DF.S~IPTION OF To P~FERRED ~MBODIM~TS

In the following description, similar features in the drawings hve been given similar reference numerals.
With reference to FIGURE 1 the probe 10 is mounted by means of bracket 12 on an automobile bumper 14. The probe 10 includes an outlet cord 16 which as illustrated is joined to the plug 18 of a block heater (not illustrated). The probe 10 has secured to the outside thereof a series of conductive rings 20, 22 and 24. The cord 16 runs through the interior of the probe 10 and the individual wires 26, 28 and 30 are connected through the probe 10 to the rings 20, 22 and 24 respectively. In the preferred case the various connections are of the three wire or grounded type.
The probe 10 may be constructed of a resilient material, such as rubber, to enable some bending and flexing in making the connection to be described. Alternatively, the probe 10 may be comprised of insulating tubing.
The forward end 32 of probe 10 is preferably rounded as illustrated.
With reference to FIGURE 2, the receptacle assembly 34 comprises the mounting frame 36 on which the receptacle tube 38 is secured. centering device or guide means 40 is secured to tube 38. The frame 36 is pivotally mounted on a bracket 42.
also mounted on bracket 42 is the stop bar assembly 44 comprising the upright member 46 and the bracing member 48.

~2~
The assembly 34 is preferably constructed of a nonconducting piping or tubing material. The three contact plates 52, 54 and 56 are secured in openings between the mounting frame 36 and the tube 38. The plates are connected on the frame side to conductors 58, 60 and 62 which form the wire 64 fitted with plug 66. The wire 64 may be extended as required to be plugged directly into an electrical outlet or may be directly wired to an outlet or other power lead. The wire 64 is located within the tubular frame 36.
The guide means 40 may preferably be a funnel shaped piece which will guide the probe 10 into the receptacle tube 38.
To facilitate alignment between the probe 10 and the tube 38, an alignment rod 68 may be secured to guide means 40. A similar rod -70 may be secured to the motor vehicle above the probe 10.
Various biasing and stabilizing members may be added to the assembly 34 to adapt the device for a particular location or vehicle type. As illustrated in E'IGURE 2, the spring 70 is attached between the llpright parts 72 of frame 36 and a forward point 74 of bracket 42. Also in that embodiment a safety switch 76 in the form of a push-button switch is secured in the side of frame 36 and connected to wire 64.
In that embodiment of the device, when the motor vehicle is driven up to the receptacle assembly 34 and the probe 10 inserted into the tube 38 by means of guide means 40, the conductive rings 20, 22 and 24 of probe 10 will make contact with the contact plates 52, 54 and 56 respectively of the tube 38. A

~3~
short further advance of the motor vehicle will cause the push button switch 76 to abut against the upright member 46 of the stop bar assembly 44, thus causing the push button to be impressed and the circuit to be completed.
In the preferred case the probe lO is wired into a light indicator in the motor vehicle which will indicate completion of the circuit.
When the motor vehicle is moved away from the receptacle assembly 34, the probe lO disengages from the tube 38 and the spring 70 causes the assembly 34 to pivot back to the original rest position. The push button switch 76 is thus moved away from the upright member 46, so that the switch deactivates.
An alternative to the push button and stop bar arrangement is the use of a biased switch activated by rotation of the upright member 46.
In the preferred case the upright part 72 of assembly 34 comprises a pair of telescoping tubes and is provided with a height adjusting screw 78, so that the height of the guide means 40 can readily be adjusted to suit the motor vehicle to be used with the device.
Thus it is apparent that there has been provided in accordance with the invention apparatus for automatically connecting a motor vehicle block heater to an electrical outlet that fully satisEies the objects, aims and advantages set forth above. While the invention has been described in conjunction with specific embodiments thereof, it is evident that many 8~
alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing decription.
Accordlngly, it is intended to embrace all such alternatives, modifications and variations as fall within the spirit and broad scope of the invention.
