Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Zwei möglichst leichte Galileische Doppelfernrohfe sind nach der Figur so nebeneinander angeordnet, daß sie nach Art der Brillen mit verschiedenen Brennweiten oder halben Gläsern vor die Augen befestigt werden.According to the figure, two Galilean double telescopes that are as light as possible are next to each other arranged that they are according to the type of glasses with different focal lengths or half Glasses are attached in front of the eyes.

Um dem Brillenträger jederzeit die Benutzung des freien Blickes zu ermöglichen, sind die Okulare und Objektive mit größeren oder kleineren Ausschnitten versehen. Es hat sichIn order to enable the wearer of glasses to use the unobstructed view at all times, are provide the eyepieces and objectives with larger or smaller cut-outs. It has

ίο als vorteilhaft erwiesen, die Okulare weiter abzuschneiden als die Objektive, da ja bekannterweise von den Okularen nur ein verhältnismäßig kleiner Teil an der Aufrichtung des Bildes teilnimmt.ίο proved beneficial to continue the eyepieces cut off than the lenses, since, as is well known, only a proportionate of the eyepieces small part participates in the erection of the image.

Die'Benutzung der Brille geschieht derartig, daß eine Schnur- oder Bandvorrichtung, welche die Brille möglichst nahe dem vorderen Schwerpunkt faßt, um den Hinterkopf geschlungen wird. Die Okularmuscheln sind zu einem breiten Stirnansatz ausgebildet, welcher zwischen den Röhren nach unten in einem Nasensteg endet. Durch diese Einrichtung wird das Gewicht der Okulare und Brille auf Stirn und Hinterkopf verteilt, so daß die Nase beim Tragen vollständig entlastet ist und- ein längerer Gebrauch der Brille ermöglicht wird.The use of the glasses happens in such a way that a cord or strap device, which grasp the glasses as close as possible to the front center of gravity, wrapped around the back of the head will. The eyepiece cups are formed into a wide forehead attachment, which between ends down the tubes in a nasal bridge. Through this facility that becomes Weight of the eyepieces and glasses distributed on the forehead and back of the head, so that the nose when worn is completely relieved and - a longer use of the glasses is made possible.

Die Benutzung der Fernbrille geschieht nach Art der Feldstecher oder Operngläser. Das lästige Halten fällt fort, die Brille sitzt fest am Kopfe, das Bild ist daher unbeweglich. Durch eine geringe Kopf- oder Augenbewegung wird die Brille in die Sehachse gebracht, oder durch umgekehrte Bewegungen dem freien Blick wieder Platz gegeben.The distance glasses are used like binoculars or opera glasses. That tiresome holding is no longer necessary, the glasses sit firmly on the head, the image is therefore immobile. With a slight head or eye movement, the glasses are brought into the visual axis, or Reverse movements give space again to the unobstructed view.
