Claims
I claim:
1. An illuminated note pad holder which comprises
a. a holder for supporting a note pad in substantially fixed
position;
b. a support for an electric light source mounted on said holder
positioned adjacent and above one peripheral portion of the
holder;
c. a wiring circuit connected to the light for supplying a source
of electricity thereto;
d. a pressure-sensitive normally closed switch interposed in said
wiring circuit and adapted to be opened in response to pressure
applied to actuating means operatively connected thereto; and
e. a receptacle associated with said holder for supporting one end
of a writing implement and having its axis tilted away from the
vertical;
f. the actuating means of said switch being positioned between the
axis of the receptacle and a vertical line struck up from the base
of the receptacle, and the diameter of the receptacle being larger
than that of the writing instrument to cause the lower end of the
instrument to pivot upwardly against said actuating means to
actuate said switch into circuit-opening position.
Description
This invention relates to note pad holders and, more particularly,
to such a holder provided with a night light.
When a note pad holder is used at a bed-side table for making notes
during the night, as by a doctor receiving a night call, it is
generally necessary to turn on a room light before the pad can be
seen for making notes. Not only is it frequently awkward to find or
reach the room light switch but the intensity of the sudden light
has a temporary blinding effect.
I have now devised a note pad holder which is provided with a night
light automatically activated by withdrawing a writing implement,
such as a pen or pencil, out of its receptacle in the pad holder.
The illuminated note pad holder of the invention comprises a holder
for supporting a note pad in substantially fixed position, a
support for an electric light source mounted on said holder
positioned adjacent and above one peripheral portion of the holder,
a wiring circuit connected to the light for supplying a source of
electricity thereto, a pressure-sensitive normally-closed switch
interposed in said wiring circuit and adapted to be opened in
response to pressure applied thereto, and a receptacle associated
with said holder for supporting a writing implement, the switch
being positioned with respect to and in communication with said
receptacle so as to be activated into circuit-opening condition by
the pressure of a writing implement positioned in said receptacle.
In a presently preferred embodiment of the invention, the
receptacle for the writing instrument is an opening having its axis
tilted from the vertical, and the pressure-sensitive portion of the
switch communicates with the upper portion of the base section of
the receptacle.
These and other novel features of the illuminated note pad holder
of the present invention will be readily understood from the
following description taken in conjunction with the accompanying
drawings in which
FIG. 1 is a perspective view of the illuminated note pad holder of
the invention;
FIG. 2 is a cross-sectional view taken along line 2--2 in FIG.
1;
FIG. 3 is a top plan view, partly broken away and in section, of
the light-containing end of the pad holder of FIG. 1;
FIG. 4 is an end elevation of the light-containing end of the
holder of FIG. 1;
FIG. 5 is a schematic circuit diagram of an embodiment of the
invention showing its operation by a writing instrument; and
FIG. 6 is a perspective view of a portion of the head of the pad
holder showing another modification of the writing instrument
receptacle.
The apparatus of the invention comprises a note pad holder 10 of
any conventional type or shape except that it is advantageously
provided with a head or top body portion 11 adapted to contain the
illuminating circuit and its components. A note pad 12 is
appropriately mounted in or on the holder 10.
Pursuant to the presently preferred embodiment of the invention,
the head body portion 11 of the note pad holder is provided with a
raised front face wall 13 in which there is mounted a socket 14 for
a light bulb 15. The body portion 11 of the pad holder is also
provided with a writing instrument receptacle 16 extending through
the top surface 17, or side surface 17a, of the body portion 11 and
downwardly into the interior of the head body portion. The size of
the receptacle 16 is advantageously slightly larger than that of
that of the writing instrument, such as a pen 18, expected to be
used with the pad holder, so that it will, by virtue of its own
weight, drop fully into the receptacle 16 when placed therein.
Also positioned in the head body portion 11 is a conventional
microswitch 20 of the type having pressure-sensitive tongue 21
which actuates the switch. The mircroswitch is so mounted in the
head portion 11 that its tongue 21 extends into the writing
instrument receptacle 16 and into the path of the writing
instrument 18 when the latter is inserted into the receptacle.
Although the receptacle axis can be vertical, I have found that, by
tilting the axis of the receptacle 16 away from the vertical any by
positioning the microswitch so that its tongue 21 is between the
axis of the receptacle and a vertical line struck up from the base
of the receptacle, the weight of the writing instrument 18, even
though much smaller in diameter than that of the receptacle, tends
to cause the lower end of the instrument to pivot upwardly against
the microswitch tongue 21. Thus, the size of the writing instrument
is not critical, and any instrument which will fit into or on the
receptacle 16 will actuate the microswitch 20.
The light bulb can be powered by batteries 22 positioned in the
head body portion 11, as sown in FIGS. 2, 3 and 4, or it can be
powered from an extraneous source such as a conventional lamp cord
attachment. In the case of a self-contained unit in which batteries
are used, the batteries are advantageously mounted in a suitable
receptacle 23 formed in the back of the head body portion 11 and
covered by a sliding panel 24, or the like.
As can be seen by reference to the representative circuit diagram
of FIG. 5, when the writing instrument 18 is in position in its
receptacle, its lower end presses against the switch tongue and
holds the switch in its open-circuit position so that the light
bulb 15 remains unlit. But when the writing instrument is withdrawn
from its receptacle preparatory to using it on the note pad, the
spring loaded switch tongue 21 moves to the closed-circuit position
and the light is energized by the power source 22.
An additional modification of a writing instrument-receptacle is
shown in FIG. 6 wherein an appropriately shaped trough 25 is formed
in the pad head with the microswitch 20 positioned in the bottom of
the trough and with its actuating tongue 21 extending upwardly.
When the writing instrument is placed in the trough 25, its weight
presses the tongue downwardly to open the circuit and turn off the
light 15.
It will be readily appreciated, accordingly, that the illuminated
note pad holder of the invention guards against inadvertent removal
of the writing instrument from the neighborhood of the pad because
the light 13 will remain lit while the writing instrument is out of
its receptacle. On the other hand, it will be seen that the pad is
not illuminated when the writing instrument is in its proper place
ready for use, and for concomitant illumination of the note pad,
whenever the writing instrument is lifted from its receptacle.
