Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to earplugs, and particularly to
an earplug combined with an elastic band that retains the earplug
close to the ear even when the earplug is not inserted in the ear
canal.
2. Description of the Prior Art
Many persons are required to use earplugs for various reasons, such
as to prevent water from reaching the wearer's inner ear during
swimming and diving. Earplugs are also employed as protection from
excessive and possibly harmful sound. A problem encountered with
the use of a conventional earplug such as that shown in, for
example, U.S. Pat. No. 1,355,276, issued Oct. 12, 1920, to F. A.
Schultz, can be that the plug is easily lost, either by becoming
dislodged from the ear while in use, or by being misplaced when
removed from the ear. Further, since it is usually inconvenient to
remove the earplugs between dives or when out of the water
temporarily, the wearer must put up with the annoyance of being
hard of hearing at such times. As a result most people who want to
wear earplugs, or who should wear them for some reason, tend not to
bother with them. Even when one who does use earplugs when engaged
in some activity, or when subjected to certain conditions, stops
that activity or ceases being subjected to those conditions for
awhile, the earplugs are difficult to store and handle so as to be
ready for the next time.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an earplug
assembly which can be worn on an ear while removed from the ear
canal and can be quickly and easily inserted into the ear canal
when needed.
It is another object of the present invention to provide an earplug
assembly that permits the earplug to be quickly and easily removed
from an ear canal when the plug is not needed.
It is still another object of the present invention to provide an
earplug which is convenient to store and handle, and is not easily
lost.
These and other objects are achieved according to the present
invention by combining an earplug with an elastic band that retains
the earplug on the ear even when the earplug is withdrawn from the
ear canal itself.
According to one preferred embodiment of the present invention, the
support is an elastic band that can be looped around the ear and
connected to the earplug. Another preferred embodiment of an
earplug support according to the present invention is an elastic
strap having a pair of spaced ends. One of the ends has an
aperture, and the other end can be pushed through the aperture to
form an endless band that fits around the ear.
The endless elastic band preferably is formed as a half-oval to
conform to the ear to provide a secure, comfortable fit. Another
feature of the present invention is the provision of a projection
on the earplug for facilitating removal of the plug from ear
canal.
These and other objects and advantages which will become
subsequently apparent in the details of construction and operation
as more fully hereinafter described in the following specification
and the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIGS. 1 and 2 of the drawings show a human head 10 with an ear 12
on which is arranged a banded earplug 14 according to the present
invention. The earplug itself is best seen in FIG. 3 of the
drawings.
The banded earplug 14 has a plug portion 16 provided with a flange
18 at one end and a flange 20 at the base thereof. The flange 20
is, itself, connected to a support in the form of an endless
elastic band 22 to retain the plug portion 16 on the ear 12 when
the plug portion is removed from the ear canal. An edge 24 of the
flange is preferably made flush with an associated surface of the
band 22 to eliminate excessive material and to facilitate fitting
the plug portion 16 into the ear canal.
The band 22 is preferably formed by molding and is in the form of a
half-oval, best seen in FIG. 3. This shape conforms generally to
the shape of the ear and permits a secure, comfortable fit of the
band around the ear.
A projection 25 may be provided on the outwardly directed surface
26 of the flange 20 to facilitate removal of the earplug 14 from
the ear. Although the projection 25 is illustrated adjacent the
juncture of the band 22 and the flange 20 and oriented parallel to
the edge 24 of the flange 20, it is to be understood that the
projection may be disposed and oriented otherwise if advantageous
to do so.
Although the endless band 22 and the flange 20 may be formed as
separate elements and suitably connected together, by a
conventional adhesive suitable for the purpose, FIG. 4 of the
drawings shows a modification of earplug 14 in which a flange 20'
and an endless band 22' are formed, or molded, in one piece to
provide a portion 27 connecting a plug portion 16' to the band
22'.
FIGS. 5 and 6 of the drawings show a modified embodiment of a
banded earplug according to the present invention with a strap 28
attached to the earplug 16 in a manner similar to that for
attachment of the earplug 16 to the band 22. Further, it is to be
understood that the plug portion 16 could be formed in one piece
the elastic strap 28 by conventional molding techniques, and the
like. The elastic strap 28 has a pair of spaced ends 30 and 32. The
end 30 is provided with an aperture 34, and the end 32 is
adjustably inserted in the aperture 34 to form an endless band that
can be looped snugly around the wearer's ear 12. The end 32 may
have a plurality of serially arranged pairs of the barbs 36 for
engaging opposite edges of the aperture 34 by a selective pair of
the barbs 36. In this manner, the end 32 can be inserted in the
aperture 34, adjusted to provide a predetermined size of the loop
formed by the strap 28, and retained at the predetermined size by
interaction of the barb 36 and the edges of the aperture 34. The
end 32 is also preferably provided with a pointed tip 38 arranged
to facilitate insertion of the end 32 into the aperture 34.
It is to be understood that banded earplugs formed according to the
present invention could be constructed in different or modified
designs from those shown in the drawings. In particular, the
designs illustrated in the drawings have been found to work well
for earplugs used by swimmers. But, a slightly different
configuration of the banded earplugs may be better when the
earplugs are to be used for sound deadening.
The endless elastic band encircling the ear need not be tight and
causes no discomfort when the plug portion is removed temporarily
from the ear canal. Also, when the plug portion is inserted into
the ear canal the endless elastic band conforms nicely to the ear.
See FIGS. 1 and 2 of the drawings.
As can be readily appreciated from the above description and from
the drawings, a banded earplug according to the present invention
is convenient to store and handle, is not easily lost, and is
convenient to put into and take out of the ear canal. A wearer can
flip the plug portion out of the ear canal while in the water after
a dive, and the like, and can reinsert the plug portion with only
one finger while either in or out of the water. Further, the plug
portion need not be pushed in tightly.
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.
