BACKGROUND OF THE INVENTION

This invention relates generally to the field of portable heating devices and more specifically to a portable foot warmer for use in bed.

During colder months of the year, a person's feet may experience an unwanted cold effect while sleeping in bed.

To remedy this condition, various solutions include the use electric warming blankets, hot water bottles and heavy socks.

However, electric blankets tend to heat the entire body, which is not ideal of it is only desired to keep the feet warm. Hot water bottles eventually cool down and socks tend to be uncomfortable and restricting. Therefore, it would be ideal to have a heating source for warming the feet while in bed that can be easily controlled, easily installed and can be selected for one or two people sleeping in the bed.

BRIEF SUMMARY OF THE INVENTION

The primary object of the invention is to provide a portable foot warmer that can easily be attached to a mattress or bed sheet and can warm the user's feet on cold nights.

Another object of the invention is to provide a portable foot warmer that can be turned on or off remotely.

Another object of the invention is to provide a portable foot warmer that can be a single warmer for a single occupant of a bed, or can be a double warmer that can be used by two occupants of a bed.

A further object of the invention is to provide a portable foot warmer that allows the power cable to be hidden between the mattress and box spring portion of the bed.

Yet another object of the invention is to provide a portable foot warmer that is very flexible, soft and thin in profile so that it does not interfere with normal sleeping activities.

In accordance with a preferred embodiment of the invention, there is disclosed a portable foot warmer comprising: one or more heating pads, a signal receiving circuit, a signal transmitting circuit, a transmitting circuit housing, an AC to DC power supply, a receiver and power supply housing, one or more electrical cables connecting said AC to DC power supply to said heating pads, said heating pads being thin and flexible and said signal transmitting circuit capable of transmitting to said receiving circuit to turn on and select heat level of said heating pad.

DETAILED DESCRIPTION OF THE DRAWINGS AND PREFERRED EMBODIMENTS

Referring now toFIG. 1we see a perspective view of main components of the invention consisting of heating pads2,4, electric cables10,14and power supply housing12. The heating pads2,4are located at the foot of a mattress8. The pads can be held in place by hook and loop fastening strips or other standard means. The pads2,4can be affixed to the top surface of a mattress8or to the top surface of a bed sheet6. The heating pads2,4are connected by cables10to AC to DC power control box12and then, via cable18to a standard AC wall socket14.

FIG. 2is a perspective view showing the addition of a standard box spring member16allowing cables10to be tucked into the space between the mattress8and the box spring16and exiting at cable18Where it can plug into wall socket14.

FIG. 3is a perspective view of a single heating pad4being used. This format is ideal for single person beds or for a couple where only one person needs the advantage of a foot warmer.

FIG. 4is a perspective view of the single heating pad version where the cables10are tucked into the space between the mattress8and the box spring16.

FIG. 5is a perspective view of a heating pad4showing the underside having Velcro or hook and loop fastening strips20,22that are attached to the heating pad4on one side and mating strips on a mattress top or sheet top. The heating pads are extremely thin and flexible, and include a felt-like top surface, so they can be attached to a bed sheet and not be a physical hindrance to normal sleeping habits. The pad4includes a top layer, a bottom layer and a central layer that has a printed carbon heating element screen printed in place. The overall size of the heating pad4is approximately twelve inches wide, twenty-four inches long and fifty thousandths of an inch thick.

FIG. 6is a perspective view of the two-pad transmitter24housed in a holding cradle30. The housing24holds a transmitting circuit, LED indicator lights, an on off switch and a battery power supply. The user can press either the switch labeled “L” or “R” or both which can activate the left heating pad2or the right heating pad4. By pressing either switch multiple times, the user can select a low, medium or high setting which is indicated by indicating lights32,34. The transmitting circuit can send a signal to a receiving circuit which is housed within the AD to DC power supply box12. The power supply is plugged into an AC wall socket14via cable18.

FIG. 7is a perspective view of a single transmitter housing36having a single activation switch38which can be pressed multiple times to set the low, medium or high setting as shown by indicator lights40.

FIG. 8is an exploded view showing how the transmitter housing24can be removed or replaced from cradle30which can be attached to a wall or other flat surface via a screw that can be inserted into aperture
