Abstract

A timed bedside night-light combination is disclosed that turns on a bedside lamp when a person steps on a mat adjacent the bed and turns on a timer when the person steps off of the mat. The timer turns off the lamp after a predetermined period of time.

Claims

1. A timed bedside night-light combination comprising:

a lamp,

a bedside mat on the floor adjacent the lamp and having pressure responsive normally open switch means therein and operating in response to pressure applied onto the mat as by a person stepping onto the mat, and

control means connected between an electric power source and the lamp and comprising a delay timer, the control means connected to the switch means, the control means also comprising a switching device closing and opening to turn the lamp on and off, the switching device closing in response to operation of the switching means to turn the light on when the mat is stepped on, and the switching device opening in response to operation of the delay timer to turn the lamp off after a predetermined delay.

2. The combination according to claim 1, wherein the switch means operates a second time when pressure is removed from the mat as by a person stepping off the mat, and wherein the delay timer is prepared for operation in response to operation of the switching means in the mat as a person steps on the mat, and said timer commences the timing in response to the second operation of the switch means to hold the switching device closed for a predetermined time after which the switching device is opened and turns out the light.

3. A timed bedside night-light combination comprising:

an electric lamp,

a bedside mat on the floor adjacent to the lamp and having switch contacts disposed throughout the mat such that foot pressure brought to bear on any foot-sized portion of the mat closes one on the switch contacts, the switch contacts being openable when such pressure is removed from the mat, and

control means between a power source and the lamp and comprising a switch for the lamp and a delay timer, the switch being closed and turning on the lamp when one of the switch contacts is closed, the switch being opened and turning off the lamp upon sensing a switching signal, the delay timer being activated for a predetermined period of time when one of the switch contacts is opened and being deactivated when the predetermined period of time expires whereupon the delay timer provides the switching signal to the switch to turn off the lamp whereby the lamp is turned on when a person steps on the mat and turned off after the predetermined period of time which starts when the person steps off of the mat.

4. The combination according to claim 3, wherein the switch contacts include two parallel strips of electrically conductive material, the strips being separated at intervals with resilient, nonconductive elements, portions of the strips disposed between the elements being engagable with each other to complete a circuit.

5. The combination according to claim 3, wherein the delay timer includes a delay adjustment means for adjusting the predetermined period of time.

6. The combination according to claim 5, wherein the delay adjustment means includes a variable resistor.

7. The combination according to claim 5, wherein the delay adjustment means is adjustable between five seconds and sixty minutes.

8. The combination according to claim 3, wherein the mat and switch contacts are operable on approximately twelve volts produced by a transformer in the control means.

9. The combination according to claim 3, wherein the lamp is operable on approximately 110 volts.

10. The combination according to claim 3, wherein the thickness of the mat is approximately one-eighth of an inch.

11. The combination according to claim 3, wherein the mat is sealed to prevent moisture from activating the switch contacts.

12. The combination according to claim 3, wherein the mat includes upper and lower vinyl layers which are sealed relative to each other on their peripheries to provide a moisture free interior, and two parallel strips of stainless steel, the strips being separated at intervals with pieces of resilient foam, the strips being engagable with each other between the foam pieces to complete a circuit.

13. The combination according to claim 3, wherein the mat is at least eighteen inches in width and at least twenty-four inches in length.

14. The combination according to claim 3, and further comprising a bed, the mat and lamp and control means being adjacent to the bed.

15. A timed bedside night-light combination comprising

a lamp adjacent to the bed and being operable on approximately 110 volts,

a bedside mat or the floor adjacent to the lamp and having upper and lower vinyl layers, each of the layers having an outer surface and a periphery, the outer surfaces being textured, the layers being sealed relative to each other on their peripheries to provide a moisture-free interior, the height of the mat being approximately one-eighth of an inch,

switch contacts disposed in the interior of the mat and including two parallel strips of stainless steel, the strips being separated at intervals with pieces of resilient foam, portions of the strips disposed between the pieces of resilient foam being engagable with each other to complete a circuit such that foot pressure brought to bear on any foot-sized portion of the mat closes one of the switch contacts, the switch contacts being openable when such pressure is removed from the mat, the switch contacts being operable on approximately twelve volts, and

control means between a power source and the light and comprising a switch for the lamp and a delay timer, the switch being closed and turning on the lamp when one of the switch contacts is closed, the switch being opened and turning off the lamp upon sensing a switching signal, the delay timer being activated for a predetermined period of time when one of the switch contacts is opened, the delay timer being deactivated after the predetermined time has expired whereupon the delay timer provides the switching signal to the switch, the delay timer further including a delay adjustment means for adjusting the predetermined period of time, the control means further including a transformer such that the switch contacts are operable on about twelve volts whereby the lamp is turned on when a person steps on the mat and turned off after the predetermined period of time which starts when the person steps off of the mat.
