Abstract

A telescopic sight mount having a base portion, cap means flexibly connected together at a joint above the center line of the sight mount and connectable to the base portion and tightening means for connecting the cap means to the base portion at a point below the center line of the sight mount is provided.

Claims

1. A telescopic sight mount having a center line midway between the top and the bottom of the sight mount removably fastenable to a firearm receiver for retaining a telescopic sight comprising in combination:

a. a base portion connectable to the firearm receiver;

b. fastening means for selectively fastening the base portion to the firearm receiver;

c. cap means flexibly connected together at a joint above the center line of the sight mount and connectable to the base portion, the cap means comprising a first part and a second part connectable to the base portion at a point below the center line of the sight mount, and the joint connects the first part and the second part above the center line of the sight and is dovetailed so that the first part flexibly interlocks with the second part along first obliquely angles surfaces on the first part and second obliquely angles surfaces on the second part; and

d. tightening means for connecting the cap means to the base portion at a point below the center line of the sight mount.

2. The apparatus according to claim 1 wherein the base portion has a plurality of screw receiving apertures therein to fasten the cap means thereto.

3. The apparatus according to claim 2 wherein the first part and the second part of the cap means each have at least one screw aperture therethrough in line with corresponding screw receiving apertures in the base portion.

4. The apparatus according to claim 3 wherein the tightening means further comprises at least one screw for each of the first part and the second part of the cap means to securely fasten the cap means to the base portion thereby causing portions of the first obliquely angled surfaces and portions of the second obliquely angled surfaces to flex apart to create a plurality of gaps between the first part and the second part of the cap means while the remaining portions of the first and second obliquely angled surfaces remain flexibly interlocked at the joint.

5. The apparatus according to claim 4 wherein the first part and the second part of the cap means each have an inner periphery and an outer periphery, at least the inner periphery being arcuate.

6. The apparatus according to claim 5 wherein the base portion further has an inner surface that is arcuate.

7. The apparatus according to claim 6 wherein the inner surface of the base portion and the inner periphery of the first part and the second part of the cap means collectively define a generally circular surface when assembled.

8. A telescopic sight mount having a center line midway between the top and the bottom of the sight mount for retaining a telescopic sight comprising in combination:

a. base portion;

b. cap means flexibly connected together at a joint above the center line of the sight mount and connectable to the base portion, the cap means comprising a first part and a second part connectable to the base portion at a point below the center line of the sight mount, and the joint connects the first part and the second part and is dovetailed so that the first part flexibly interlocks with the second part along first obliquely angled surfaces on the first part and second obliquely angled surfaces on the second part; and

c. tightening means for connecting the cap means to the base portion at a point below the center line of the sight mount so that when tightened the cap means flexes at the joint.

9. The apparatus according to claim 8 wherein the first part and the second part of the cap means each have at least one screw aperture therethrough in line with screw receiving apertures in the base portion.

10. The apparatus according to claim 9 wherein the tightening means further comprises at least one screw for each of the first part and the second part of the cap means to securely fasten the cap means to the base portion thereby causing portions of the first obliquely angled surfaces and the second obliquely angled surfaces to flex apart to create a plurality of gaps between the first part and the second part of the cap means while the remaining portion of the first and second obliquely angled surfaces remain flexibly interlocked at the joint.

11. The apparatus according to claim 10 wherein the first part and the second part of the cap means each have an inner periphery and an outer periphery, at least the inner periphery being arcuate.

12. The apparatus according to claim 11 wherein the base portion further has an inner surface that is arcuate.

13. The apparatus according to claim 12 wherein the inner surface of the base portion and the inner periphery of each of the first part and the second part of the cap means collectively define a generally circular surface when assembled.

14. The apparatus according to claim 13 wherein the telescopic sight mount further is adapted to receive and retain a telescopic sight between the cap means and the base portion.

15. The apparatus according to claim 14 wherein the telescopic sight mount further is removably fastenable to a firearm receiver by fastening means.

16. The apparatus according to claim 15 wherein the base portion further comprises at least one aperture through which the fastening means removably fasten the telescopic sight mount to the firearm receiver.

17. A telescopic sight mount having a center line midway between the top and the bottom of the sight mount for retaining a telescopic sight comprising in combination:

a. a base portion;

b. cap means comprising a first part and a second part flexibly connected together at a dovetailed joint above the center line of the sight mount and connectable to the base portion; and

c. tightening means for connecting the cap means to the base portion so that when tightened the cap means flexes at the joint.

18. The apparatus according to claim 17 wherein the cap means further is connectable to the base portion at a point below the center line of the sight mount.

19. The apparatus according to claim 18 wherein the dovetailed joint further comprises first obliquely angled surfaces on the first part of the cap means and second obliquely angled surfaces on the second part of the cap means so that the first part flexibly interlocks with the second part along the first obliquely angled surfaces and the second obliquely angled surfaces.

20. The apparatus according to claim 19 wherein the first part and the second part of the cap means each have at least one screw aperture therethrough in line with screw receiving apertures in the base portion.

21. The apparatus according to claim 20 wherein the tightening means further comprises at least one screw for each of the first part and the second part of the cap means to securely fasten the cap means to the base portion thereby causing portions of the first obliquely angled surfaces and the second obliquely angled surfaces to flex apart to create a plurality of gaps between the first part and the second part of the cap means while the remaining portion of the first and second obliquely angled surfaces remain flexibly interlocked at the joint.

22. The apparatus according to claim 21 wherein the first part and the second part of the cap means each have an inner periphery and an outer periphery, at least the inner periphery being arcuate.

23. The apparatus according to claim 22 wherein the base portion further has an inner surface that is arcuate.

24. The apparatus according to claim 23 wherein the inner surface of the base portion and the inner periphery of each of the first part and the second part of the cap means collectively define a generally circular surface when assembled.

25. The apparatus according to claim 24 wherein the telescopic sight mount further is adapted to receive and retain a telescopic sight between the cap means and the base portion.

26. The apparatus according to claim 25 wherein the telescopic sight mount further is removably fastenable to a firearm receiver by fastening means.

27. The apparatus according to claim 26 wherein the base portion further comprises at least one aperture through which the fastening means removably fasten the telescopic sight mount to the firearm receiver.
