Abstract
The customized clear, free from impediment, obstruction, or hindrance, or the translucent or transparent transmission of light is permitted to shine through an injected or poured pliable plastic which could be PVC, formulated to emit the maximum even dispersion of LED (light emitting diodes), illumination. The single or multiple LEDs are fitted into a cavity usually in the back of the plastic unit in order for the emission of light to pass through the unit. This light emitting unit is usually molded for application onto wearable apparel, accessories or decorative items and can be molded into varying shapes, colors, designs or logos with impressions within or on the surface in flat, two dimensional or three dimensional properties for illumination and exploitation of said unit. With the LEDs fitted or inserted into said unit and connected to a power source the said unit will emit light throughout the light transmitting device evenly and uniformly, thus attracting attention specifically to the illuminated image, logo or item rather than lighting for illuminations sake.
Description
BACKGROUND OF THE INVENTION
This invention relates to improvements in wearable illuminated ornamentation or amusement devices. More particularly, the invention pertains to an article which may be incorporated or other affixed or secured onto wearable apparel, accessories, decorative items, toys or games, including for instance hats, jackets, shirts, backpacks or shoes.
Illuminated decorative objects have been known for sometime which provide illumination of the LED through a battery source. Examples include U.S. Pat. Nos. 5,018,053, 5,253,149 and 4,009,381. These patents use a lighting source such as an LED powered by a battery and connected onto attachable clips, posts or the jewelry itself and are intolerant to impact, modification or flexibility of the items. The purpose of the LED's is to project light, and hence to illuminate another object.
In other prior illuminating devices, lighting of object is performed using fiber optics to obtain a back lighting which is relatively low in intensity when used for flat image or surface viewing. The optical fiber is usually not positioned directly under or integrated within the item to be illuminated making previous patents less efficient, vulnerable to separation, impact or flexibility. Thus, although such prior devices are known to serve their purposes, they have proven to be neither satisfactory nor do they reach maximum exploitation of uniform light illumination.
Thus, a need thus exists for an even more improved flexible, thin-format, light transmissive device which will insure even distribution of brightness while providing maximum illumination for logos, images or items within or on the surface of said item.
SUMMARY OF THE INVENTION
A light source, such as an LED (light emitting diode), is inserted into a cavity accessible from the back of a clear or translucent light transmitting pliable molded unit, which could be PVC, and could have a logo, image or other graphic element imbedded within or disposed on the surface of said unit. The unit is preferably molded into a three dimensional or planar configuration designed and constructed so as to allow the light to scatter evenly through the unit and illuminate graphic element. The light source is connected to an energy supply, which is typically a battery, through a switching mechanism. The switching mechanism may be either simple on/off switch, or it may be an electronic timing circuit which can turn the source on or off cyclically at a predetermined or variable duty cycle and frequency. Alternatively, a motion-activated switch, or a switch operating randomly may be used as well.

DETAILED DESCRIPTION OF THE INVENTION
Generally speaking, the present invention is directed to an lighted or illuminated ornamentation or amusement device comprising, a relatively thin, light-transmissive unit, a light source and a power source providing energy to the light source. A switching mechanism is also provided for selectively activating the light source. The unit is preferably flexible or pliable and is made of a plastic material such as PVC. The unit has a somewhat three dimensional or planar configuration and has a top surface on which there is formed customized image, a logo or other graphic elements. Alternatively the image may be imbedded into the unit. The unit is secured by sewing or other means to a wearable apparel, accessory, decorative item, a toy or a garment so on.
More specifically, referring to FIGS.
1
-
3
, a unit
13
is shown as having a generally circular, oval or ellipsoid shape with a top surface
16
and a bottom surface
16
A. Of course, unit
13
may have any other shape as well. The unit
13
is made pliable so that it can be bent as illustrated by the dotted lines in FIG.
2
. Top surface
16
includes one or more graphic elements
11
which form a predetermined design. The elements
11
may be painted onto surface
16
or maybe imbedded into the unit
13
.
The unit
13
also has a circumferential lip
12
which may be used to secure the unit
13
to a garment or other article. The top surface
16
may be separated from the lip by a cylindrical side wall
14
. The unit
13
is formed with a cavity
17
disposed at the center of the unit
13
and extending into the unit
13
from bottom surface
16
A. Cavity
17
is structured to receive a light-source such as an LED
20
(shown in
FIG. 5
) which transmits light evenly through unit
13
as indicated in
FIG. 1
by arrows R. More particularly the light from source
20
is transmitted uniformly around and through said unit
13
and highlighting the graphic elements
11
.
FIG. 4
shows that instead of a single LED receiving cavity, the unit
13
can be made with two or more cavities
18
,
19
, each receiving an appropriate light source.
Referring now to
FIG. 5
, LED
20
is shaped and sized so that it can be inserted into cavity
17
. A wire
21
connects LED
20
to a male plug
22
.
There is also provided an electronic unit having a housing
30
with a female plug
25
for receiving male plug
22
. Housing
30
also has a cover
24
with an activating switch
23
. The switch
23
may be used to selectively activate LED
20
and as such, it may be an off/switch or a motion detector switch. Alternatively, as shown in
FIG. 8
in which cover
14
has been removed, housing
30
may include a cavity C for a battery (not shown) and a PC board
29
with an electronic chip
28
. Chip
28
may be activated by switch
23
to turn LED
20
on and off in a cyclical pattern. Alternatively, chip
28
may activate the LED in a random pattern.
FIG. 6
shows two LEDs
20
,
20
a
inserted into cavities
18
,
19
respectively and connected to the electronic unit by male plug
22
.
Of course, instead providing the LED and electronic unit as separate elements requiring a connecting wire and male and female connectors, a single housing
31
may be provided with the LED
20
extending outwardly.
FIGS. 9 and 10
show a possible combination for this embodiment.
In these figures, unit
29
is provided not only with an LED
20
, but also batteries
31
. For this purpose, cavity
17
is enlarged so that unit
29
can fit within.
FIGS. 11 and 12
shows the top and side view respectively of a molding piece
35
usually generated by C.A.D., (computer aided design). The piece
35
could be cut out of brass or aluminum, or other similar materials.
The unit
35
has three specifically spaced circular pegs
32
,
33
,
34
.
The second molding piece
36
is generally flat and is formed on its top surface with two holes
37
and
38
. In between these holes, a cavity
40
is formed in the size and shape of the plastic unit to be formed, such as, for instance, the plastic unit
13
of FIGS.
1
-
3
. In order to make unit
13
, molding piece
35
is placed over piece
36
and lowered (as seen in
FIG. 13B
) until pins
32
and
34
fit into holes
38
and
37
as best seen in FIG.
13
a
. Once the piece
35
is in place plastic material is poured into cavity
40
to generate unit
13
.
The primary usage of the usually circular pegs
32
,
34
, are for joining and stabilizing both mold pieces
35
,
36
insuring the specific placement, setup and quality of the intended poured images on unit
13
, while circular peg
33
, is specifically designated and designed to form the cavity
17
of the LED. Additional or different pegs may be used for forming cavities for electronic units or other items.
FIGS. 14
,
14
a
,
15
and
16
show an assembly
42
attached to various types of articles such as a hat, a backpack or a jacket. In each case, the assembly
42
can be made of discrete parts as shown in
FIGS. 5 and 7
, or a single housing such as shown in
FIGS. 9 and 10
.
Obviously numerous modifications may be made to this invention without departing from its scope as defined in the appended claims.
