Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a headmounted light for use in connection with
illumination. The headmounted light has particular utility in connection with providing
a hands-free source of illumination without tethering the user to external equipment.
2. Description of the Prior Art
Headmounted lights are desirable for providing a hands-free source of
illumination without tethering the user to external equipment. Surgeons typically
use headmounted lights when performing operations. Traditional designs require
the user to connect the headmounted light to an external light source. This greatly
limits the user's freedom of movement during use: either the external light source
has to move with the user, or the user has to unplug from the external light source.
The latter situation is particularly disadvantageous since the headmounted light
no longer provides illumination when unplugged. Headmounted lights of the current
invention eliminate this inconvenience by providing a light source that attaches
to the user along with a headband-mounted lens assembly. The invention allows the
user to move freely without any need to maintain a connection to an external light source.
The use of battery power and light belts is known in the prior art. For example,
U.S. Pat. No. 6,260,978 to St. John discloses a battery power and light belt. However,
the St. John '978 patent does not have a fiber-optic cable, and has further drawbacks
of lacking an adjustable mount for the light.
U.S. Pat. No. 4,298,913 to Lozar discloses an illuminating apparatus that mounts
on the body of a person. However, the Lozar '913 patent does not have a fiber-optic
cable, and additionally does not have an adjustable mount for the light.
Similarly, U.S. Pat. No. 3,830,230 to Chester discloses a surgical headlamp
that permits several degrees of freedom of movement of a high-intensity headlight
with respect to a headband worn by a user. However, the Chester '230 patent does
not have a power source, and cannot emit light without being connected to an external
light source.
In addition, U.S. Pat. No. Des. 399,580 to Feinbloom discloses a deluxe surgical
head light that attaches to a user's head. However, the Feinbloom '580 patent does
not have a fiber-optic cable, and also does not have a light source.
Furthermore, U.S. Pat. No. 5,430,620 to Li et al. discloses a compact
surgical illumination system capable of dynamically adjusting the resulting field
of illumination that provides illumination. However, the Li et al. '620 patent
does not emit light without being connected to an external light source, and further
lacks a power source.
Lastly, U.S. Pat. No. 6,224,227 to Klootz discloses a surgical headlight
assembly with detachable video-camera module that allows viewers at a remote location
to observe an operation procedure on a video monitor from a surgeon's visual perspective.
However, the Klootz '227 patent does not have a power source, and has the additional
deficiency of requiring a connection to an external light source in order to emit light.
While the above-described devices fulfill their respective, particular objectives
and requirements, the aforementioned patents do not describe a headmounted light
that allows providing a hands-free source of illumination without tethering the
user to external equipment. The St. John '978 patent, the Lozar '913 patent, and
the Feinbloom '580 patent make no provision for a fiber-optic cable. The St. John
'978 patent and the Lozar '913 patent lack an adjustable mount for the light. The
Chester '230 patent, the Li et al. '620 patent, and the Klootz '227 patent cannot
emit light without being connected to an external light source. The Chester '230
patent, the Li et al. '620 patent, and the Klootz '227 patent do not have a power
source. The Feinbloom '580 patent lacks a light source.
Therefore, a need exists for a new and improved headmounted light that
can be used for providing a hands-free source of illumination without tethering
the user to external equipment. In this regard, the present invention substantially
fulfills this need. In this respect, the headmounted light according to the present
invention substantially departs from the conventional concepts and designs of the
prior art, and in doing so provides an apparatus primarily developed for the purpose
of providing a hands-free source of illumination without tethering the user to
external equipment.

end so that it can removably enclose a housing 18. Housing 18 encloses
a light source 22, a power source 54, and an on/off switch 20.
The opposing side of pouch 16 has a switch hole 50 that allows on/off
switch 20 to protrude from pouch 16. In the current embodiment, light
source 22 is a light bulb and power source 54 is a rechargeable battery.
On/off switch 20 controls the flow of electrical current from power source
54 to light source 22. Housing 18 is removably secured within
pouch 16 by straps 26. Light source 22 is connected to lens
assembly 42 by fiber-optic cable 30. Fiber-optic cable 30
is removably attached to belt 14 and a headband 34 by clips 28.
Lens assembly 42 has a lens 44 enclosed by a reflector 46
and an adjustable mount 48 connecting the rear of the reflector 46
to the front of the horizontal portion 36 of headband 34. The reflector
46 and lens 44 direct light transmitted from fiber-optic cable 30
to the object to be illuminated (not shown). The adjustable mount 48 allows
the user to aim the lens assembly 42 to direct light to the desired location.
The headband 34 has a vertical portion 38 with its opposing ends
attached to the front and rear of the horizontal portion 36. The headband
protrusions 40 extend from the middle of the vertical portion 38
and increased the user's comfort level by distributing the weight of the headband
34 over a larger portion of the user's head. A friction locking mechanism
32 attached to the rear of the horizontal portion 36 also increases
the user's comfort by allowing the size of the horizontal portion 36 of
headband 34 to be adjusted.
Moving on to FIG. 2, a new and improved belt 14 of the present invention
for providing a hands-free source of illumination without tethering the user to
external equipment is illustrated and will be described. More particularly, the
belt 14 has a side release buckle 12 removably connecting its opposing
ends. The pouch 16 has one side attached to the middle of belt 14.
On/off switch 20 is visible protruding through the switch hole 50
in pouch 16. Hook and loop fasteners 52 are shown removably attaching
straps 26 to the opposing side of pouch 16 to removably retain housing
18 within pouch 16. Housing 18 encloses power source 54
and light source 22. Fiber-optic cable 30 is visible extending from
belt 14.
Continuing with FIG. 3, a new and improved belt 14 of the present
invention for providing a hands-free source of illumination without tethering the
user to external equipment is illustrated and will be described. More particularly,
the belt 14 has a side release buckle 12 attached to the opposing
ends of belt 14. Clips 28 are shown removably attaching fiber-optic
cable 30 to belt 14. Connector 24 removably connects one end
of fiber-optic cable 30 to light source 22. On/off switch 20
is visible protruding from pouch 16. Hook and loop fastener 52 removably
attaches strap 26 to pouch 16. Housing 18 encloses light source
22, power source 54, and on/off switch 20.
Concluding with FIG. 4, a new and improved pouch 16 of the present
invention for providing a hands-free source of illumination without tethering the
user to external equipment is illustrated and will be described. More particularly,
the pouch 16 has a belt 14 attached to one side of pouch 16.
Housing 18 is shown removed from pouch 16. The strap 26 is
shown with the hook and loop fastener 52 disengaged so that housing 18
can be removed from pouch 16. The housing 18 encloses on/off switch
20, light source 22, and power source 54. Connector 24
is shown disconnected from light source 22. Clip 28 is visible removably
attaching fiber-optic cable 30 to the belt 14.
In use, it can now be understood that the user inserts a charged battery into
housing 18 and then places housing 18 into pouch 16 so that
on/off switch 20 protrudes from switch hole 50. The straps 26
with hook and loop fasteners 52 are used to retain housing 18 within
pouch 16. The user employs side release buckle 12 to secure belt
14 about his or her waist. The user then connects one end of fiber-optic
cable 30 using connector 24 to light source 22. The user places
headband 34 on their head, and he or she adjusts its size using friction
locking mechanism 32. On/off switch 20 is placed in its on position
to cause light to be emitted from lens assembly 42. The user can aim the
light emitted through lens 44 in the desired direction by adjusting adjustable
mount 48. The user switches on/off switch 20 to its off position
to turn off light source 22. When the headmounted light 10 is no
longer needed, the user removes headband 34 and belt 14.
While a current embodiment of the headmounted light has been described in detail,
it should be apparent that modifications and variations thereto are possible, all
of which fall within the true spirit and scope of the invention. With respect to
the above description then, it is to be realized that the optimum dimensional relationships
for the parts of the invention, to include variations in size, materials, shape,
form, function and manner of operation, assembly and use, are deemed readily apparent
and obvious to one skilled in the art, and all equivalent relationships to those
illustrated in the drawings and described in the specification are intended to
be encompassed by the present invention. For example, any suitable light source
such as a light emitting diode may be used instead of the light bulb described.
Also, the rechargeable battery may also be a regular battery or a fuel cell. Furthermore,
a wide variety of headband size adjustment mechanisms may be used instead of the
fraction locking mechanism described.
Therefore, the foregoing is considered as illustrative only of the principles
of the invention. Further, since numerous modifications and changes will readily
occur to those skilled in the art, it is not desired to limit the invention to
the exact construction and operation shown and described, and accordingly, all
suitable modifications and equivalents may be resorted to, falling within the scope
of the invention.
