Description
A number of proposals are present in the prior art for illuminated
footwear including battery-powered circuits and various lighting
arrangements. The difficulty with all of these prior art devices
has been complexity of construction and consequently costs too
great to justify manufacturing. Standard footwear designs have not
lent themselves readily to incorporation of the prior art
illuminating means. On and off switching arrangements are either
nonexistent or cumbersome.
It is the objective of the present invention to completely overcome
these difficulties and to provide illuminating means for footwear
which is entirely practical, economical, sturdy and simplified.
Other objectives will be apparent during the course of the
description.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to the drawing in detail, wherein like numerals designate
like parts, the numeral 10 designates a shoe in its entirety which
may be constructed from conventional materials including leather
and plastic and whose particular shape or design may vary within
the scope of the invention. The shoe includes the usual upper 11
having a suitable sole 12 and a tubular seam 13 is provided
extending entirely around the top edge of the upper 11. A vertical
heel seam 14 is also formed at the rear of the shoe in accordance
with conventional practice.
A readily removable heel 15 is provided whose detailed construction
will be described and these above-described components coact with
the illuminating means which form the actual subject matter of the
invention.
The heel 15 constitutes a unit having a top thin plate 16 fixed
thereto and received slidably within knuckles 17 at the opposite
sides of another plate 18, anchored to the bottom of the heel
portion of the shoe upper. This construction enables the heel 15 to
be easily slid onto or off of the shoe upper as when the battery is
to be replaced.
The heel 15 has an internal vertical battery compartment 19 adapted
to contain a small dry cell battery 20 having one terminal thereof
in electrical contact with a metallic spring element 21 in the
bottom of the compartment 19, in turn electrically connected with a
wire 22 leading upwardly along one side of the battery, as shown in
FIGS. 2 and 7. The other terminal 23 of the battery is at its top,
near the top of the compartment or chamber 19.
A switching arm or blade 24 has its rear end portion pivoted by an
element 25 to a part of the slide plate 16 and this arm has a
forward handle extension 26 disposed immediately in front of the
heel 15 and closely beneath the instep portion of the shoe so as to
be conveniently located and yet substantially concealed and away
from contact with obstructions. The extension 26 is downwardly
offset from the remainder of the arm 24 as best shown in FIG. 1.
The arm 24 has a notch 27 in one side thereof adjacent the battery
terminal 23 so that the switch arm will be fully out of contact
with this terminal when the the arm is in an "off" position, as
shown in FIG. 7. When shifted to the "on" position, the arm 24 will
move over the contact 23 and engage the same electrically as best
shown in FIG. 2.
The "on" and "off" positions of the switch arm 24 are positively
established by the coaction of an arcuate slot 28 formed in the arm
and a quick release pin fastener 29 which serves also to
releaseably anchor the heel 15 to the shoe upper so that it will
not be accidentally dislodged from the flanges 17 if the heel
strikes some obstruction during walking. As shown, the fastener 29
has a head 30 above the plate 18 and has a cross pin 31 for
releasable engagement in a locking cavity 32, FIG. 6, at the bottom
of a passage 33 in the heel 15 which receives the shank of the
fastener 29. The passage 33 also has side grooves 34 which allow
the cross pin 31 to enter the locking cavity 32 when the fastener
29 is applied to positively connect the heel to the shoe. Were it
not for the fastener 29, the heel could slide out of the flanges 17
upon striking some obstruction during walking. As explained, the
fastener 29 also forms a convenient "off"-"on" limit stop for the
pivoted switch arm 24 by virtue of the slot 28. It should be
understood that other forms of fasteners may be employed if
desired, although the present fastener is a convenient quick
release device and entirely practical. The head 30 of the fastener
is covered and concealed by a protective layer 35 in the insole,
FIG. 1.
The arm 24, when in contact with the terminal 23, completes an
electrical circuit through the plate 18 having a wire 36
electrically connected therewith. These two wires pass upwardly
through the heel seam 14 of the shoe and one wire extends forwardly
through the tubular seam 13 along each side of the shoe at its top,
one of the wires being shown in FIG. 3.
At the front of the tubular seam 13 and the front of the foot
receiving opening, FIG. 4, the wires 22 and 36 emerge and carry a
socket connector 37 adapted to receive a light bulb 38 whose
terminals cause the light bulb filament to be in series with the
wires 22 and 36 leading from and to the battery 20 in a simple
series circuit containing a manual "off"-"on" switch afforded by
the arm 24. The socket element 37 has a tongue 39 projecting
beneath a small strap 40 conveniently formed by slitting the shoe
upper. Other arrangements may be employed for anchoring the socket
connector 37 to the shoe, such as a separable snap fastener or the
like. The socket 37 and light bulb may be of the screw-threaded
type, bayonet slot type, or other known arrangements. A preferably
translucent decorative piece 41 of any preferred design
frictionally fits over the light bulb 38 to complete the decorative
assembly.
It should be apparent that a number of modifications, not shown,
are possible within the scope of the invention. Plural decorative
lights may be provided along the seam 13 connected similarly to a
string of Christmas tree lights. The size and shape of the battery
may be altered in accordance with various heel styles. The entire
heel with battery could be provided as a throwaway unit. However,
in all cases, the invention will be characterized by the simplified
and convenient "on"-"off" switch construction and the circuit wires
extending in a concealed manner through the existing seam. The
advantages of the invention and its economies should now be readily
apparent to those skilled in the art.
It is to be understood that the form of the invention herewith
shown and described is to be taken as a preferred example of the
same, and that various changes in the shape, size and arrangement
of parts may be resorted to, without departing from the spirit of
the invention or scope of the subjoined claims.
