Patentiert im Deutschen Reiche vom 3. September 1912 ab.Patented in the German Empire on September 3, 1912.
Die Erfindung betrifft eine Ohrenschutzvorrichtung, mit einem in den Gehörgang einschiebbaren hohlen Gummikörper und besteht darin, daß der hohle Gummi körper durch ein im Innern angreifendes mechanisches Druckmittel derart ausdehnbar ist, daß der Gehörgang schnell abgeschlossen und wieder freigegeben werden kann.The invention relates to an ear protection device with one that can be pushed into the ear canal hollow rubber body and consists in that the hollow rubber body through a Mechanical pressure medium acting on the inside is expandable in such a way that the auditory canal can be completed and released quickly.
Auf der Zeichnung ist der Erfindungsgegen- !o stand in verschiedenen Ausführungsformen dargestellt, und zwar zeigen:In the drawing, the subject of the invention is shown in different embodiments, namely show:
Fig. ι eine Ansicht des Verschlusses,Fig. Ι a view of the closure,
Fig. 2 einen Längsschnitt im Aufriß nach der Linie A-B in Fig. i,FIG. 2 is a longitudinal section in elevation along the line AB in FIG.
Fig. 3 und 4 die Spannfeder allein im Aufriß und im Profil.Fig. 3 and 4 the tension spring only in elevation and in profile.
Fig. 5 und 6 zeigen je einen Längschnitt im Aufriß einer zweiten Ausführungsform, 'bei der an Stelle der Spannfeder ein kolbenartiger Stößel tritt.5 and 6 each show a longitudinal section in elevation of a second embodiment, 'at which is replaced by a piston-like plunger instead of the tension spring.
Fig. 7 und 8 zeigen eine dritte Ausführungsform. Schließlich stellt Fig. 9 die Benutzungsweise einer solchen Vorrichtung dar.Figs. 7 and 8 show a third embodiment. Finally, Fig. 9 illustrates the mode of use such a device.
Die Erfindung besteht aus einem dem Gehörgang angepaßten, zweckmäßig aus Gummi hergestellten elastischen Mantel 1, der mit einem wulstartig ausgebildeten Vorsprung 2 versehen ist. In den Mantel 1 ist eine Spannfeder 3 mit Formbügel 4 eingebaut, welcher der Form des Gummimantels -i die Kugelgestalt gibt. Die Enden der Spannfeder 3 dehnen die Wulst 2 aus. Die Schleife der Spannfeder 3 ist in der halben Breite der Schenkel durchgeführt, wodurch sich ein Druck auf die Schenkel hauptsächlich in der Schleife bemerkbar macht. Das Einsetzen des Verschlusses ι erfolgt durch Zusammendrücken der beiden Schenkel, wodurch der Verschlußkopf ι verkleinert und das Einführen des Verschlusses in den Gehörgang 12 ermöglicht wird. Beim Nachlassen des Druckes durch Freigabe der Feder 3 erweitert sich der Verschlußkopf und schließt den Gehörgang ab. Der Vorsprung 2 legt sich gegen den Rand des Gehörganges in der Ohrmuschel und verhindert ein zu weites Einschieben des Verschlusses. The invention consists of an adapted to the ear canal, expediently made of rubber produced elastic jacket 1, which with a bead-like projection 2 is provided. In the jacket 1, a tension spring 3 with shaped bracket 4 is installed, which the shape of the rubber jacket -i gives the spherical shape. Stretch the ends of the tension spring 3 the bead 2 off. The loop of the tension spring 3 is half the width of the legs performed, which puts pressure on the thighs mainly in the loop makes noticeable. The closure ι is inserted by pressing it together of the two legs, whereby the breech head ι is reduced and the introduction of the Closure in the ear canal 12 is made possible. When the pressure is released When the spring 3 is released, the breech head widens and closes the ear canal. The projection 2 lies against the edge of the ear canal in the auricle and prevents it pushing the lock in too far.
Die Dehnung ,des Verschlußkörpers 1 kann anstatt durch die Feder 3 auch durch Verschieben eines kolbenartigen Stößels 5, 6 erfolgen, indem der Kolben die entsprechend gestaltete Innenwand des Gummikörpers und damit auch die Außenwand ausdehnt, so daß der Gehörgang abgeschlossen und der Verschluß in ihm festgehalten wird. Der Ring 7 verhindert ein zu weites Vordringen des Kolbens. The elongation of the closure body 1 can instead of the spring 3, it can also be done by moving a piston-like plunger 5, 6, in that the piston expands the correspondingly designed inner wall of the rubber body and thus also the outer wall, so that the ear canal is closed and the closure is held in it. The ring 7 prevents the piston from advancing too far.
Der hohle Gummimantel 1 kann ferner mittels der in einem vor seiner öffnung angeordneten Bällchen 8 befindlichen Luft ausgedehnt werden. Das Bällchen 8 ist mit einer Verdickung 9 versehen, an welcher ein Verschlußhäkchen 10 angebracht ist. Letzteres läßt sich an einer öse 11 befestigen.The hollow rubber jacket 1 can also be arranged in front of its opening by means of the Ball 8 located in the air to be expanded. The ball 8 is provided with a thickening 9 on which a locking hook 10 is attached. The latter can be attached to an eyelet 11.
Claims (1)
Ohrenschutzvorrichtung, aus einem in den Gehörgang > einschiebbaren hohlen Gummikörper bestehend, dadurch gekennzeichnet, daß der hohle, am Außenteil mit dickerem Abschlußring ausgestattete Gummikörper (i) durch ein im Innern angreifendes Druckmittel (z. B. Feder, Luft o. dgl.) in seinem Volumen veränderlich ist, so daß er unter Beschränkung des Dehnungsdruckes in den Gehörgang eingeschoben und in dem letzteren unter Freigabe oder Herstellung des Dehnungsdruckes festgehalten werden kann.Patent claim:
Ear protection device, consisting of a hollow rubber body which can be pushed into the auditory canal, characterized in that the hollow rubber body (i) equipped with a thick end ring on the outer part is pressed in by a pressure medium (e.g. spring, air, etc.) acting on the inside its volume is variable, so that it can be pushed into the ear canal with restriction of the stretching pressure and held in the latter with release or production of the stretching pressure.
