Ear protection, consisting of a flexible elongated soft plastic body such as silicone, on its lateral surface at least one annular channel is formed, characterized that in addition circumferential sealing ring (6) made of plastically malleable material available is and that this used in one of the ring channels (5) or used is, wherein the sealing ring material radially over the annular channel side walls at least slight protrudes.
The 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.
The 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 is visible.
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.
Though 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.
task 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.
These The task is done by hearing protection solved with the feature of claim 1. Further advantageous embodiments The invention are characterized in the subclaims.
the according to is additionally one circumferential sealing ring made of wax or other soft plastic moldable Material present in at least one of the ring channels of the hearing protection body used or is insertable, wherein the sealing ring material radially over the Annulus side surfaces at least slightly protrudes, preferably correspondingly curved. Preferably while using the so-called "ear wax", like it z. B. also in the wax balls of the company Ohropax GmbH available is and that of a special wax mixture with embedded fine cotton wool or cotton threads exists, which prevent a break-up of the wax mass (see also under www.ohropax.de). When applying this new ear or hearing protection The soft deformable sealing ring adapts to wax or other moldable materials (in the form of plasticine) the individually shaped ear canal optimal. The deformable sealing ring mass thus fits the ear canal shape even if it is irregular, by being plastically inelastic at the auditory canal wall pressed accordingly is applied. Because no elastic Restoring forces to In addition, no pressure is exerted on the auditory canal walls, especially after prolonged Wearing a hearing protection could make it uncomfortable.
The ear protection body can be an in have substantially cylindrical shape, with in the insertion cambered or rounded tapered headboard in hat or mushroom shape and with a handle portion, between these two parts of the annular channel is provided with a smaller diameter, in which then inserted the ear wax ring or cast and axially supported on the annular channel walls.
When Hearing protection body can but also a normal market above-described ear plug serving on the lateral surface at least two soft-flexible, radially facing slats are provided, the form an annular channel between them. The best known of these hearing protectors usually has four lamellae, so with three ring channels between this, where it makes sense the ear wax ring in the middle Provide annular channel. It is also advantageous if about a third the ring height over the channel height or the slat walls outstanding protrudes, which then also sufficient wax is available, too extreme deformations to withstand.
to better handling is the handle part of the hearing protection body with Profiling, such as grooves, waves, notches, flats, various depressions or coarsely porous consistency of the outer skin, to ensure a very good grip during insertion and removal, as this Ear plugs during his Proper handling, respectively axially inserted or pushed out or pressed and at the same time is subjected to an at least slight rotational movement.
Also in the ear canal sealing ear wax ring may be different in combination with the body or plug part be provided. Thus, the ear wax as a ring with circular, oval or square cross section manufacturer side in the body-ring groove be poured.
Of the Earwax ring can also be used as a separate earwax strand manufactured according to cross section, z. B. be extruded and on corresponding circumferential length cut off and then inserted into the annular groove and the strand sides sticking together pressed together become.
It But it can also because the ear wax depending on the duration of use and / or Input and output frequency worn and / or unattractive, will be beneficial if one Hearing protection body not only a wax ring is assigned but whose several are present then z. B. in each case a body at least two, but advantageously several, earwax strands corresponding Length as replacement parts are assigned. Is an ear wax ring that has been used several times already unsightly or otherwise damaged, then this wax material is easily removed from the annular channel and a new ear wax strand in these appeal. It can of course instead of single strand pieces certain length also a longer one Ear wax strand associated with a plug body be and you can then cut off from this long strand as needed correspondingly shorter pieces and the plug body with to be refitted.
Around when storing the hearing protection z. B. in a jar or in a box a "lie" of the relatively soft-deformable Wax ring, z. B. a one-sided flattening on the support side, to avoid is in the appropriate storage part, z. B. the Box base, an insert with a correspondingly shaped recess provide that with the outside dimensions of hearing protection. It makes sense, although the corresponding cover part in the same Way has a profiled insert, so that the hearing protection of the invention is practically completely enclosed and the wax or sealing ring undergoes no deformation. On the contrary, by appropriate formations in the box can wax rings deformed by previous use in the ear in a concentric uniform ring shape reshaped become. Of course is that in these storage containers, so box or Can, at least one hearing protector either parallel or vertically inserted recording takes place. at parallel or horizontal recording of Wachsring earplugs is the box dividing plane in the axis plane of the hearing protection to provide while for vertical insertion or insertion of the hearing protection in the lower box part, the parting plane or surface and at the same time the insertion depth of the hearing protection, the radial center plane of the sealing or wax ring or of this bearing ring groove is.
following The invention will be described with reference to several embodiments with reference to the drawing closer explained.
