The invention relates to a hearing protection according to the preamble of the claim
1, in particular as noise,
Sound, wind and / or water protection is used.
As hearing protection, there are currently essentially three different systems available on the market:
- - balls of so-called ear wax or very soft silicone, which are applied in the ear canal,
- - roll-shaped or otherwise (eg unilaterally conical or tronic) molded foam materials which are compressed prior to application and re-expand in the ear canal;
- - Made of silicone or other materials existing fittings with radially encircling slats.
currently the most common on the market
Hearing protection devices
are z. As the "hearing protection guide" SonicShop
GmbH, D-71254 Ditzingen, which is also available at www.SonicShop.info
There are described among other things:
- - bathing roll from Ohropax, which is intended to protect against ingress of water, but is not sufficient as noise protection;
- - Ear wax balls, also of ear plugs, which become deformable by Rolien between the fingers, and consisting of wax material with integrated textile or cotton wool fibers, which do not exert any unpleasant elastic pressure, but their re-application may be problematic because these wax pieces are not provided with handle parts;
- - Foam ear protection with or without grooved profile on the outer surface or with foam shield, as well as in the DE 697 32 021 T2 described, but which can give an uncomfortable wearing feeling, because of the elastic pressure they exert in the ear canal;
- - Ear plug with a flexible centric stick, at one end of the plug-in thin, mushroom-shaped opposite to the direction of insertion extending membrane slats are provided from very flexible material such. B. also in the DE 699 18 490 T2 and DE 100 40 766 A1 described;
- - Ear plug with filter system (called "earplanes"), consisting of a flexible elongated body, on the lateral surface of which a plurality of radial flanges or soft-flexible, substantially radially-facing fins are provided, which are arranged in axial spacing to each other, as well eg in the DE 42 17 043 A1 and the. DE 697 20 151 T2 described in the latter, a combination of two elastic materials of different hardness is used.
let the last two types of ear plug through the
easily insert very soft fins into the ear canal. However, they can
the soft but in the form fixed slats the very
different individual ear canal shapes and cross sections
not optimally adapt, so that these unpleasant pressure sensations
cause in the ear and / or a complete seal of the ear canal
(as required, for example, to protect against the ingress of water)
not sufficiently guarantee.
The invention is therefore an ear protection of the above genus
on the one hand offers a very good hearing protection, with good grip
both during insertion and during execution and optimally circumferentially adapts to the ear canal
and causes only a very low foreign body sensation;
this with a simple structure and handling.
The task is done by hearing protection

How out 1 can be seen, there is the hearing protection according to the invention 1 from an elongated, rotationally symmetrical body 2 , its introductory part 3 as a rounded insertion head 4 is formed, which has the shape of a hat or mushroom and the one annular channel 5 assigned. In this ring channel 5 is a sealing ring 6 inserted or cast, which consists of plastically deformable material, for. B. from earwax, also known from the wax balls of Ohropax GmbH. The body 2 points adjacent to the annular channel 5 a support shoulder 7 and axially following this a slimmer cylindrical or slightly conical handle portion 8th on.
The in 2 illustrated hearing protection 10 shows an embodiment in which the body 2 at the introductory 3 a conical insertion head 4 owns and over the ring channel 5 spaced a radially facing, insertion slightly bevelled blade 11 owns, followed by a slender cylindrical handle part 8th , Again, in the ring channel 5 a sealing ring 6 Made of soft elastic deformable plastic material, such as earwax, molded.
3 shows an embodiment in which an ear protection 13 from a commercially available lamellar body 14 consists, at the insertion side slightly conically tapered insertion part soft elastic slats radially projecting slightly bevelled insertion, wherein between the slats in each case an annular channel 5 is formed. The narrow insertion head 4 is insertion-rounded dome-shaped and protrudes radially lamellar, while the axially opposite handle part 8th slightly conically tapered is formed. In the middle ring channel here is a sealing ring 6 intended.
In 4 is shown as a hearing protection 1 in vertical orientation, with the insertion head 4 down, in the lower part of the box 16 a receiving box is inserted and that in a provided in this recording profile 17 , Here is the recording profile 17 designed so that it is the upper box part surface 18 towards a ring part 19 possesses, in the inserted state of hearing protection 1 its sealing ring 6 surrounds to its radial center plane. The upper box lid 20 is at the same time designed so that it over the lower part of the box 16 in the adjusted state protruding part of the hearing protection 1 takes shape, wherein the molded in the cover part receiving profile 21 a similar ring part 19 As the lower part of the box has, so that when vertically nesting the two box parts 16 and 20 the plastically deformable sealing ring 6 , which has been sensibly already pushed radially by hand, is deformed back to an optimal ring shape.
In 5 is shown as in a lower box part 16 an ear protection 1 is horizontally inserted and that in a recording profile 22 , which corresponds to the outer profile of the axial half of the hearing protection. Thus lies the axis 23 of hearing protection in the plane of the upper surface 18 of the lower part of the box 16 , An identical profile 22 is also in the upper part of the box 20 provided, so that in the closed state of the box, so in full succession resting the two box parts 16 and 20 , the ring parts 19 the two box parts the plastically deformable sealing ring 6 wrap around and thereby deform accordingly or deform back into the desired shape.
In 6 is finally shown as in a lower box part 16 on the one hand, hearing protection 1 is inserted and right of it sealing ring strand pieces 24 , These are inserted here in a curly form. But they can also be inserted as straight strand pieces or in any form in the box, preferably in corresponding recesses. Furthermore, in the left part of the box is a long sealant strand 25 to recognize, which is folded together to save space in the form of a spiral. Of course, the relatively long strand in meandering form or around the center here arranged hearing protection 1 be provided laid. Also, any further, space-saving and / or useful arrangement of the strand 25 possible, depending on the space and size relationships.
