Claims
Having described my invention, I claim:
1. In combination with a firearm having an iron sight mounted on an
elongated barrel:
a telescopic sight;
base plate means mounted on the firearm, said base plate means
having V-shaped longitudinal, parallel ridges along opposite sides
thereof;
a pair of longitudinally spaced supports mounted on the base plate
means, each support including a body having a semi-cylindrical wall
for receiving the telescopic sight, and a pair of spaced side walls
having upper edges integrally connected to the convex side of the
semi-cylindrical wall, and lower edges with opposed V-shaped
grooves mated with ridges of the base plate means, such that the
semi-cylindrical wall is spaced above the base plate means to
permit the user to view the iron sight along a line of sight
between the base plate means and the telescopic sight;
a fastener connected to both side walls of each support adjacent
the base plate means, the fastener being operative to move one of
said side walls toward the other side wall to releasably clamp the
base plate means between the lower edges of the side walls;
a half ring for each support, each half ring having its mid-section
mounted on the telescopic sight adjacent the support, the means for
connecting opposite sides of each half ring to opposite sides of
each semi-cylindrical wall to prevent movement of the telescopic
sight with respect to the supports.
2. A combination as defined in claim 1, in which the base plate
means has a pair of openings aligned on opposite sides of the base
plate means for receiving each fastener member.
3. A combination as defined in claim 1, in which the side edges of
the base plate means are adapted to slideably receive the opposed
grooves of said parallel walls.
Description
BACKGROUND OF THE INVENTION
This invention is related to telescopic sight mountings and more
particularly to a mounting that permits a firearm user to employ
either the telescopic sight or the firearm's iron sights.
Commercial mountings for telescopic sights usually employ an
elongated base plate that is mounted on the firearm's receiver. The
sight is supported by two mating pairs of half rings, mounted along
the base plate. Some mountings support the sight in a raised
position above the receiver so that the user can view the iron
sights mounted on the firearm barrel without having to remove the
telescopic sight.
SUMMARY OF THE INVENTION
The broad purpose of the present invention is to provide a dual
sight mounting having a pair of half rings connected together for
supporting a telescopic sight, one of the rings having a pair of
integrally connected, relatively movable walls which are clamped on
opposite sides of the base plate in such a manner that the user can
view the iron sights along a line of sight passing between the two
walls.
Still further objects and advantages will become readily apparent
to those skilled in the art to which the invention pertains upon
reference to the following detailed description.
DESCRIPTION OF THE DRAWINGS
The description refers to the accompanying drawings in which like
reference characters refer to like parts throughout the several
views and in which:
FIG. 1 is a perspective view of a rifle having a telescopic sight
supported by a sight mounting illustrating the preferred embodiment
of the invention;
FIG. 2 is a view of one of the sight supports of FIG. 1, with the
telescopic sight removed for purposes of the description;
FIG. 3 is an exploded view of the support of FIG. 2; and
FIG. 4 is an enlarged sectional view of the support of FIG. 2
showing the manner in which the base plate is clamped between the
walls that define the opening for viewing the iron sights.
DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to the drawing, FIG. 1 illustrates a conventional rifle
10 having an elongated barrel 12. An iron sight 14 is mounted on
the barrel. A telescopic sight 16 is supported by mounting means 18
on the receiver portion of barrel 12.
Mounting means 18 comprises an elongated base plate 20 and a pair
of supports 22 and 24. Supports 22 and 24 are identical to one
another and are mounted along base plate 20. Base plate 20 is
connected by appropriate fasteners to the receiver of rifle 10.
Support 22, illustrated in FIG. 2, comprises a body 26 having a
semicylindrical wall 28, and a pair of short co-planar walls 30 and
32 connected to the opposite side edges of wall 28. A half ring 34
is mounted on walls 30 and 32. Half ring 34 has a cylindrical
portion 36 which cooperates with wall 28 to form an opening for
receiving telescopic sight 16. Four set screws 38 connect the
opposite sides of half ring 34 to walls 30 and 32 to clamp
telescopic sight 16 to body 26.
A lower pair of substantially parallel spaced walls 40 and 42 are
integrally connected to opposite sides of body 26. As best
illustrated in FIG. 4, the lower edges of walls 40 and 42 have
opposed V-shaped grooves 44 and 46 respectively mated with
complimentary shaped ridges 48 and 50 formed along the longitudinal
side edges of base plate 20.
Walls 40 and 42 are slightly flexible so as to be movable with
respect to one another. An elongated threaded fastener 52 is
mounted on the two walls as shown in FIG. 4 such that the user can
clamp the base plate 20 between the two walls. Base plate 20 has a
pair of openings 54 and 56 for receiving fastener 52 to locate body
26 with respect to the base plate. The opposite end of the base
plate has a second pair of openings (not shown) for accommodating
the fastener associated with support 24.
As best illustrated in FIG. 2, walls 40 and 42 support the
telescopic sight in a position above barrel 12 so that the user can
view iron sight 14 by a line of sight passing between the two
walls. By forming the lower edges of walls 40 and 42 to mate with
base plate 20, the telescopic sight can be readily attached to or
removed from the rifle. In addition, the preferred embodiment of
the invention employs only a single fastener 52 for connecting each
support to the base plate. Thus the mounting assembly can be
economically manufactured because it requires fewer components than
other commercially available mounts.
