Claim 0:
1. A binocular comprising: a first tube and a second tube, connected to one another by means of a hinged bridge pivotable about a hinge axis for adjusting an interpupillary distance and for parallel arrangement of the first and second tubes, wherein the first tube and the second tube each include:
an objective lens;
an eyepiece;
a prism erecting system; and
a focusing lens, wherein the focusing lens is axially displaceable,
wherein the focusing lens of the first tube is positioned between the objective lens of the first tube and the prism erecting system of the first tube;
wherein the focusing lens of the second tube is positioned between the objective lens of the second tube and the prism erecting system of the second tube;
wherein a first beam path is formed in the first tube by a first optical axis of the objective lens of the first tube, a second optical axis of the eyepiece of the first tube, and the prism erecting system of the first tube,
wherein a second beam path is formed in the second tube by a first optical axis of the objective lens of the second tube, a second optical axis of the eyepiece of second tube, and the prism erecting system of the second tube,
a focusing knob rotatable about a rotational axis, wherein the rotational axis of the focusing knob is arranged coaxially to the hinge axis; and
a first push rod and a second push rod, wherein the focusing knob is coupled to each of the first and second push rods, the first push rod is coupled to the focusing lens within the first tube, and the second push rod is coupled to the focusing lens within the second tube,
wherein the first push rod is held in a guide tunnel in a first tube housing of the first tube and the second push rod is held in a guide tunnel in a second tube housing of the second tube,
wherein one end of the first push rod is arranged in the first tube and another end of the first push rod is arranged in the hinged bridge and one end of the second push rod is arranged in the second tube and another end of the second push rod is arranged in the hinged bridge,
wherein the first and second push rods are displaceable back and forth in the guide tunnel of the corresponding first and second tube housing,
wherein the direction of the back-and-forth displacement in the guide tunnel and a direction of the hinge axis are aligned obliquely with respect to each other.
