NAIL POLISH DRYER
Abstract
A horizontally disposed tray is free to move forwardly and
rearwardly in a horizontal plane. A switch operated by the tray's
movement is connected to a timer. The timer energizes a plurality
of heat sources. When the tray is moved forward, it is disposed
underneath the heat sources and the heat sources are energized for
a predetermined time by the timer.

Claims
We claim:
1. A nail polish dryer comprising:
A horizontally disposed tray, the tray being mounted in a manner
that it is free to slide forwardly and rearwardly in a horizontal
plane;
a plurality of heat sources, the heat sources being disposed
forward of and above the tray, in a position that sliding the tray
forwardly places the tray in a position where the tray will be
exposed to the heat produced by the heat sources; and
means cooperating with the said tray and heat sources, the means
causing the heat sources to be energized when the tray is in its
forward position and causing the heat sources to be deenergized
when the tray is in its rearward position.
2. The device of claim 1 wherein the heat sources include
conventional infra-red bulbs.
3. The device of claim 2 wherein the means includes a switch and a
timer, the switch causing the timer to energize the heat sources
for a predetermined period of time when the tray is in its forward
position, the switch being closed by tray movement into the forward
position and being opened by tray movement into the rearward
position.
4. The device of claim 3 further including a hollow housing in
which the lamp and tray are disposed, said housing having interior
walls with an interior coating of heat reflective material.
Description
SUMMARY OF THE INVENTION
The invention is a device which will speed the drying of polish on
finger or toe nails after the polish has been applied.
To this end, a horizontally disposed tray is free to move forwardly
and rearwardly in a horizontal plane. The tray is heat resistant
and is slightly grooved to fit hands or feet. Means cooperating
with the tray cause heat sources to be energized and deenergized.
When the tray is in its forward position, it is heated by the heat
sources.
Thus, when a user wishes to dry polish on finger or toe nails, the
user places a hand or foot on the tray and pushes the tray forward,
keeping the hand or foot on the tray. The nails are thus heated and
dried by the heat sources. Sliding the tray rearwardly deenergizes
the heat sources.
BRIEF DESCRIPTION OF THE DRAWINGS
In the drawings:
FIG. 1 is a drawing of one form of the invention in use;
FIG. 2 is a side view of the structure of FIG. 1;
FIG. 3 is a drawing of a modification of the invention for use with
both hands of the user simultaneously; and
FIG. 4 is a circuit diagram of the invention.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Referring now to the drawings, wherein like elements are denoted by
like identification numbers in all the figures, a hollow body 10
with a horizontal base, two vertical walls and a rearwardly and
upwardly extending top terminating in a rear rectangular opening 80
bears rubber pads 20 underneath the base to prevent slippage. A
horizontally disposed rectangularly shaped tray 30 is free to move
forwardly and rearwardly in a horizontal plane on rollers 40 which
are mounted in the body and are disposed in a common horizontal
plane with their axes parallel. A switch 50 cooperating with the
tray is closed and activates a timer 60 when the tray is in its
forward position, directly beneath infra-red bulbs 70 which are
mounted in the body. The tray extends through the opening, and is
disposed below a clear rectangular plastic shield 90 which is
disposed in the upper part of the opening. A power cord 100
connected to a switch 110 supply power to the device. The interior
surfaces of the device are silvered to reflect the heat from the
bulbs.
Thus, when the switch 110 is closed and the cord is connected to a
power source, pushing the tray forward with the hands will activate
the timer and energize the heat sources for the period set on the
timer, drying the nails of the user's hands which are placed on the
tray. If the interior of the device becomes too warm for the user,
withdrawing the tray shuts the device off.
The timer is manually resettable and must be reset each time it
opens the circuit to deenergize the lamps after the preset period
has expired.
While the invention has been described with detailed reference to
the drawings, the protection sought is to be limited only by the
terms of the claims which follow.
