Abstract

Disclosed herein are a piece of furniture and a method for dispensing diapers. The furniture keeps diapers neatly organized and conveniently accessible for dispensing. The furniture has an elongated interior space, a platform, a lead screw, a motor, a detector, and a processor. The platform can hold a stack of diapers and move the stack of diapers so they can be dispensed from the top of the piece of furniture. Rotating a lead screw raises and lowers the platform within the piece of furniture. A detector positioned at the top of the interior space of the piece of furniture is configured to detect when a diaper is dispensed from the interior space. A processor in communication with the detector and the motor is configured to activate the motor, thereby raising the platform, when the detector detects that a diaper has been dispensed from the piece of furniture.

Claims

1. A piece of furniture for dispensing diapers comprising:

an elongated interior space having a cross-sectional area less than 100 square inches;

a platform within the interior space for holding stacked diapers, wherein the stacked diapers can be dispensed from a top of the interior space;

a lead screw coupled to the platform, wherein rotation of the lead screw raises the platform within the interior space;

a motor configured to rotate the lead screw;

a detector positioned at the top of the interior space and configured to detect when a diaper is dispensed from the interior space; and

a processor in communication with the detector and the motor, wherein the processor is configured to activate the motor, thereby raising the platform, when the detector detects a diaper has been dispensed from the top of the interior space.

2. The piece of furniture of claim 1, wherein the motor is a gear motor.

3. The piece of furniture of claim 1, wherein the detector is selected from the group consisting of a photoelectric sensor, a reflective photoelectric sensor, photoelectric switch, proximity sensor, through-beam photoelectric sensor, laser sensor, or ultrasonic sensor.

4. The piece of furniture of claim 1, further comprising a lid at the top of the interior space.

5. The piece of furniture of claim 4, wherein the lid is operably coupled to a second detector configured to detect whether the lid is open or closed.

6. The piece of furniture of claim 5, wherein the second detector is configured to send a signal to the processor and the processor is configured to activate the motor, thereby lowering the platform, when the second detector detects the lid has been opened.

7. The piece of furniture of claim 5, wherein the second detector is selected from the group consisting of a snap action switch, action switch, magnetic switch, pressure sensor, rocker switch, slide switch, photoelectric sensor, photoelectric switch, proximity sensor, or reflective photoelectric sensor.

8. The piece of furniture of claim 1, wherein a third detector has been configured to detect when the platform has been lowered to a point set as the low-level set point position within the interior space.

9. The piece of furniture of claim 8, wherein the third detector sends a signal to the processor, wherein the processor is configured to stop the motor, thereby stopping the platform, when the third detector detects the platform has been lowered to the point set as the low-level set point position within the interior space.

11. The piece of furniture of claim 1, further comprising a position sensor configured to determine the position of the platform and send a signal encoding the position of the platform to the processor.

12. The piece of furniture of claim 11, wherein the position sensor is selected from the group consisting of a shaft encoder, laser sensor, ultrasonic sensor, or rotor encoder.

13. The piece of furniture of claim 11, wherein the processor is configured to transmit the position of the platform to a digital readout, such as a gauge, a display, or a wireless device selected from the group consisting of a smartphone, a tablet, or a personal computer.

14. The piece of furniture of claim 11, wherein the processor is configured to transmit the data encoding the position of the platform to a wireless device via the internet.

15. The piece of furniture of claim 1, wherein the lead screw is operably coupled to the platform using a nut.

16. The piece of furniture of claim 1, wherein the lead screw is operably mounted within the interior space using a flange bearing.

17. The piece of furniture of claim 1, wherein the platform is guided vertically within the interior space by a guide rod, guide rail, or guide channel.

10. The piece of furniture of claim 10, wherein the third detector is selected from the group consisting of a snap action switch, action switch, magnetic switch, pressure sensor, rocker switch, slide switch, photoelectric sensor, photoelectric switch, proximity sensor, or reflective photoelectric sensor.
