Description
Oppfinnelsen angår et hørselsvern som kan benyttes sammen med brillestenger, omfattende en klokke og en rundt klokkens åpning festet tetningsring. The invention relates to a hearing protector that can be used together with eyeglass frames, comprising a bell and a sealing ring fixed around the opening of the bell.
De hørselsvern som finnes på markedet, er beskaffet slik at de under bruk sammen med briller, kommer i en slik stilling at brillestengene havner mellom hørselsvernets tetningsring og bærerens hode. Den lydlekkasje som derved oppstår, med-fører at hørselsvernets lyddempningsevne blir kraftig nedsatt. Videre oppstår det ubehag for bæreren, da brillestengene trykker mot øret og hodet. The hearing protectors on the market are designed in such a way that, when used with glasses, they come into such a position that the glasses rods end up between the sealing ring of the hearing protector and the wearer's head. The sound leakage that occurs as a result means that the hearing protection's sound dampening ability is greatly reduced. Furthermore, discomfort arises for the wearer, as the glasses' temples press against the ear and head.
Det er også kjent å forsyne brillestenger med ørepropper. Denne løsning er imidlertid ikke alltid tilfreds-stillende, da man vil oppnå riktig tilpasset demping for hvert tilfelle. Dessuten anses ørepropper for å være uhygienske. It is also known to provide eyeglass frames with ear plugs. However, this solution is not always satisfactory, as you want to achieve properly adapted damping for each case. Also, earplugs are considered unhygienic.
Foreliggende oppfinnelse angår et effektivt støy-dempende hørselsvern, som er bekvem å bære og som passer sammen . med annet utstyr slik som briller, ansikstmaske og hjelm. Denne hensikt oppnås ved å forsyne øreklokkens tetningsring med spor eller lommer for brillestengene. The present invention relates to an effective noise-reducing hearing protector, which is comfortable to wear and which fits together. with other equipment such as goggles, face mask and helmet. This purpose is achieved by providing the earcup's sealing ring with grooves or pockets for the eyeglass rods.
Oppfinnelsen skal i det følgende beskrives nærmere under henvisning til tegningen, som viser et eksempel på oppfinnelsen. In the following, the invention will be described in more detail with reference to the drawing, which shows an example of the invention.
Fig. 1 viser en av de to øreklokkene, og fig. 2 viser klokken sett fra siden. Fig. 1 shows one of the two earmuffs, and fig. 2 shows the clock seen from the side.
En lydisolerende klokke 2 inneslutter bærerens ene . øre. Rundt klokkens åpning er det anordnet en tetningsring 3 som med hele sin anleggsflate uhindret ligger an og tetter mot bærerens hode. Tetningsringen er ved klokken forsynt med et i det vesentlige koaksialt anordnet, ringformet spor 4 i et plan som fortrinnsvis er parallelt med tetningsringens plan. Sporet er slik anordnet at det opptar en brillestang 5 og er så dypt som mulig for at brillen ikke skal * innta en feil stilling og derved nedsette synsskarpheten. A soundproof bell 2 encloses the wearer's one. ear. A sealing ring 3 is arranged around the bell's opening, which with its entire contact surface rests unhindered and seals against the wearer's head. At the bell, the sealing ring is provided with an essentially coaxially arranged, ring-shaped groove 4 in a plane which is preferably parallel to the plane of the sealing ring. The groove is arranged in such a way that it accommodates a spectacle rod 5 and is as deep as possible so that the spectacles do not * take up an incorrect position and thereby reduce visual acuity.
