Abstract

In a sight scope, an erect sleeve is received in a scope body. An erect lens system is disposed within the erect sleeve. An erect lens system is pivotably supported at its end portion on the side of an eye piece by the scope body. The other end portion of the erect sleeve on the side of an objective is biased by a spring so as to contact an inner end face of an adjusting member of an inclination adjusting mechanism. The end portion of the erect sleeve on the side of the objective is moved by the adjusting member in a direction perpendicular to an axis of the scope body. By this, the erect sleeve is adjusted in its angle of inclination with respect to the axis of the scope body. A projection is formed on that end portion of the erect sleeve on the side of the objective. The projection is tapered when viewed in a direction perpendicular to the axis of the scope body. A top portion of this project is in contact with the inner end face of the adjusting member.

Claims

1. A sight scope comprising:

(a) a sleeve-like scope body having an objective lens system on a front end portion thereof and an eyepiece lens system on a rear end portion thereof;

(b) an erect sleeve received in said scope body, an erect lens system being supported within said erect sleeve, one end portion of said erect sleeve being pivotably supported by said scope body; and

(c) inclination adjusting means for inclining said erect sleeve with respect to an axis of said scope body by moving the other end portion of said erect sleeve in a direction perpendicular to the axis of said scope body, said inclination adjusting means including an adjusting member and a spring, said adjusting member extending through said scope body in such a manner as to be perpendicular to the axis of said scope body and being threadedly engaged with said scope body, said spring being adapted to bias the other end portion of said erect sleeve so as to be brought into abutment with an inner end face of said adjusting member, thereby the inclination of said erect sleeve being determined by said adjusting member;

(d) one of the inner end face of said adjusting member and an outer peripheral surface of the other end portion of said erect sleeve being provided as a first surface and the other, as a second surface, a projection being formed on said first surface, said projection being tapered when viewed in a direction perpendicular to the axis of said scope body, a distal portion of said projection being in contact with said second surface.

2. A sight scope according to claim 1, wherein the outer peripheral surface of the other end portion of said erect sleeve is provided as said first surface and has said projection, the inner end face of said adjusting member being provided as said second surface, the inner end face of said adjusting member being a flat surface perpendicular to an axis of said adjusting member.

3. A sight scope according to claim 2, wherein said projection extends in a circumferential direction of said erect sleeve and is in point-contact with the inner end face of said adjusting member.

4. A sight scope according to claim 3, wherein said adjusting member extends vertically through said scope body and said adjusting means includes another adjusting member extending horizontally through said scope body, said projection being of a ring-like configuration and in point-contact with the inner end faces of said adjusting members.

5. A sight scope according to claim 2, wherein said projection is of a conical configuration.

6. A sight scope according to claim 2, wherein the distal portion of said projection is linear, said distal portion being perpendicular to the axis of said scope body and parallel to the inner end face of said adjusting member, the distal portion of said projection being in line-contact with the inner end face of said adjusting member.

7. A sight scope according to claim 1, wherein the inner end face of said adjusting member is provided as said first surface and the outer peripheral surface of the other end portion of said erect sleeve is provided as said second surface, said projection being formed on an axis of said adjusting member in the center of the inner end face of said adjusting member and being of a conical configuration.

8. A sight scope comprising:

(a) a scope body having an axis;

(b) a sleeve received in said scope body, said sleeve supporting at least one lens, said sleeve having one end portion pivotably supported by said scope body and an other end portion;

(c) an adjusting member extending through said scope body perpendicularly to the axis of said scope body and being threadedly engaged with said scope body;

(d) a spring adapted to bias the other end portion of said sleeve so as to be brought into abutment with an inner end face of said adjusting member;

(e) one of the inner end face of said adjusting member and an outer peripheral surface of the other end portion of said sleeve being provided as a first surface and the other, as a second surface, a projection being formed on said first surface, said projection being tapered toward a distal portion of the projection when viewed in a direction perpendicular to the axis of said scope body, the distal portion being in contact with said second surface.

9. A sight scope according to claim 8, wherein the outer peripheral surface of the other end portion of said erect sleeve is provided as said first surface and has said projection, the inner end face of said adjusting member being provided as said second surface, the inner end face of said adjusting member being a flat surface perpendicular to an axis of said adjusting member.

10. A sight scope according to claim 9, wherein said projection extends in a circumferential direction of said erect sleeve and is in point-contact with the inner end face of said adjusting member.

11. A sight scope according to claim 10, wherein said adjusting member extends vertically through said scope body, said sight scope further comprising another adjusting member having an inner end face, said another adjusting member extending horizontally through said scope body, said projection being of a ring-like configuration and in point-contact with the inner end faces of said adjusting members.

12. A sight scope according to claim 9, wherein said projection is of a conical configuration.

13. A sight scope according to claim 9, wherein the distal portion of said projection is linear, said distal portion being perpendicular to the axis of said scope body and parallel to the inner end face of said adjusting member, the distal portion of said projection being in line-contact with the inner end face of said adjusting member.

14. A sight scope according to claim 8, wherein the inner end face of said adjusting member is provided as said first surface and the outer peripheral surface of the other end portion of said erect sleeve is provided as said second surface, said projection being formed on an axis of said adjusting member in the center of the inner end face of said adjusting member and being of a conical configuration.
