Footrest with integral heater
View Patent ↗A footrest is provided comprising a base portion for placement on a supporting surface, a footplate connected to the base portion for receiving a foot of a user of the footrest, a heater connected to the base portion, an air intake system connected to the heater for drawing a first mass of air into the footrest, and an exhaust connected to the heater for expelling a second mass of air from the footrest. The heater receives the first mass of air, heats it, and expels it as a second mass of air. A warm air shield helps redirect the second mass of air expelled through the exhaust at the foot of the user placed on the footplate. The footplate may be made to pivot with respect to the base portion, or may be provided with a control knob so that a user may control the heater using her foot.
1. A footrest comprising:
a base portion for placement on a supporting surface;
a footplate connected to the base portion for receiving a foot of a user of the footrest;
a heater connected to the base portion;
a warm air shield attached to the base portion;
an air intake system connected to the heater for drawing a first mass of air into the footrest; and
an exhaust connected to the heater for expelling a second mass of air from the footrest;
wherein the heater receives the first mass of air through the air intake and expels the second mass of air through the exhaust; and
wherein the warm air shield redirects the second mass of air expelled through the exhaust at the foot of the user.
2. The footrest of claim 1 , wherein the heater warms the first mass of air to a defined temperature to produce the second mass of air.
3. The footrest of claim 2 , wherein defined temperature is selected by the user.
4. The footrest of claim 2 , wherein defined temperature is selected by the user through a control knob mounted on the footplate capable of being operated by the foot of the user.
5. The footrest of claim 1 , wherein the warm air shield includes one or more recesses for receiving an instep of the foot of the user.
6. The footrest of claim 1 , wherein the footplate is pivotable with respect to the base portion.
7. The footrest of claim 6 , wherein the footplate may be pivoted to and held in a plurality of user selected pivot positions.
8. The footrest of claim 1 , wherein the footplate includes one or more friction elements to grip the foot of the user.
9. The footrest of claim 1 , wherein the footplate is capable of receiving a pair of feet of a user of the footrest.
10. The footrest of claim 1 , further comprising a second footplate;
wherein the second footplate may be used in conjunction with the footplate to receive a pair of feet of a user of the footrest, with both the footplate and the second footplate each receiving one of the pair of feet.
11. The footrest of claim 10 , wherein each of the footplate and the second footplate may be independently pivoted to and held in a plurality of user selected pivot positions.
12. The footrest of claim 1 , wherein the base portion is vaulted and forms an extended arch.
13. The footrest of claim 1 , wherein the heater includes a fan for drawing the first mass of air through the air intake, and expelling a second mass of air through the exhaust.
14. The footrest of claim 1 , wherein the fan is a radial fan.
15. The footrest of claim 2 , wherein heater includes a nichrome wire heating element for warming the first mass of air to a defined temperature to produce the second mass of air.
16. The footrest of claim 2 , wherein heater includes safety device to disable the heater in the event that the first mass of air is heated substantially above the defined temperature.
17. A footrest comprising:
a base portion for placement on a supporting surface;
a footplate connected to the base portion for receiving a foot of a user of the footrest;
a heater connected to the base portion;
a warm air shield attached to the base portion;
an air intake system connected to the heater for drawing a first mass of air into the footrest; and
an exhaust connected to the heater for expelling a second mass of air from the footrest;
wherein the heater receives the first mass of air through the air intake and expels the second mass of air through the exhaust;
wherein the second mass of air is expelled through the exhaust from a location in front of the foot in a substantially vertical direction directly onto the warm air shield; and
wherein the warm air shield redirects the second mass of air expelled through the exhaust at the foot of the user.
18. The footrest of claim 17 , wherein the warm air shield includes one or more recesses for receiving an instep of the foot of the user.
