Abstract
Abstract An observation periscope which can be combined with a laser distance measuring device, wherein at least one mirror located forwardly of the periscope objective is arranged to be rotatable about the optical axis of the periscope objective relative to a support and pivotable about the elevation axis. The infeed of the laser beam between the periscope objective and the mirror arranged forwardly thereof and into the latter occurs with the aid of two mirrors which are positively aligned relative to one another.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
119 words
An observation periscope arrangement equipped with a periscope objective and capable of being combined with a laser distance-measuring device, comprising a periscope objective having an optical axis, a peRiscope support for mounting said periscope objective, mirror means having an elevational axis and disposed forwardly of the periscope objective, means mounting at least said mirror means to be rotatable about the optical axis of the periscope objective and relative to the periscope support and pivotable about said elevational axis of said mirror means, two mirrors cooperating with said mirror means, and means for aligning said two mirrors relative to one another for introducing a laser beam between the periscope objective and the forwardly arranged mirror means and into the latter.
Claim 2
Dependent Claim
119 words
An observation periscope arrangement equipped with a periscope objective and capable of being combined with a laser distance-measuring device, comprising a periscope objective having an optical axis, a peRiscope support for mounting said periscope objective, mirror means having an elevational axis and disposed forwardly of the periscope objective, means mounting at least said mirror means to be rotatable about the optical axis of the periscope objective and relative to the periscope support and pivotable about said elevational axis of said mirror means, two mirrors cooperating with said mirror means, and means for aligning said two mirrors relative to one another for introducing a laser beam between the periscope objective and the forwardly arranged mirror means and into the latter.
Claim 3
Dependent Claim
71 words
The arrangement as defined in claim 1, said periscope objective having a field of view, said mirror means having a field of view, said two mirrors defining a first mirror and a second mirror, said aligning means including means for mounting said first mirror eccentrically with respect to the periscope objective externally of said field of view of said periscope objective and within the field of view of said mirror means.
Claim 4
Dependent Claim
40 words
The arrangement as defined in claim 2, said first mirror having a sighting axis, and said mounting means for said first mirror mounting said first mirror with its sighting axis substantially parallel to the optical axis of the periscope objective.
Claim 5
Dependent Claim
80 words
The arrangement as defined in claim 1, further including a rotatable component cooperating with one of said mirrors, said aligning means incorporating first means for eccentrically mounting said one mirror at said rotatable component and second means for rotatably mounting the other mirror at said periscope support, said first and second mounting means for said two mirrors mounting said two mirrors to be rotatable about a respective axis which is substantially parallel to the optical axis of the periscope objective.
Claim 6
Dependent Claim
22 words
The arrangement as defined in claim 4, wherein said rotatable component cooperates with said periscope support for rotatably mounted said periscope objective.
Claim 7
Dependent Claim
21 words
The arrangement as defined in claim 4, wherein said rotatable component constitutes part of said mounting means for said mirror means.
Claim 8
Dependent Claim
67 words
The arrangement as defined in claim 4, wherein said first and second mounting means for each of said two mirrors comprises a respective holder for each of said two mirrors, and said aligning means for said two mirrors further incorporates a cable which is under tension, said cable being fixedly mounted at the holder for one mirror and displaceably guided at the holder of the other mirror.
Claim 9
Dependent Claim
148 words
An observation periscope arrangement equipped with a periscope objective and capable of being combined with a laser distance-measuring device, comprising a periscope objective having an optical axis and a field of view, a periscope support for mounting said periscope objective, mirror means having an elevational axis and a field of view, said mirror means being disposed forwardly of the periscope objective, said mirror means having an elevational axis and a field of view, means mounting at least said mirror means to be rotatable about the optical axis of the periscope objective, two mirrors, means mounting said two mirrors so as to cooperate with said mirror means, said mounting means for said two mirrors including means for mounting one of said mirrors eccentrically with respect to the periscope objective externally of the field of view of the periscope objective and within the field of view of the mirror means.
Claim 10
Dependent Claim
148 words
An observation periscope arrangement equipped with a periscope objective and capable of being combined with a laser distance-measuring device, comprising a periscope objective having an optical axis and a field of view, a periscope support for mounting said periscope objective, mirror means having an elevational axis and a field of view, said mirror means being disposed forwardly of the periscope objective, said mirror means having an elevational axis and a field of view, means mounting at least said mirror means to be rotatable about the optical axis of the periscope objective, two mirrors, means mounting said two mirrors so as to cooperate with said mirror means, said mounting means for said two mirrors including means for mounting one of said mirrors eccentrically with respect to the periscope objective externally of the field of view of the periscope objective and within the field of view of the mirror means.
