Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of Invention
[0002] The invention relates to rifle sight mounts and more
particularly to an improved sight mount for securing a telescopic
sight to a mounting rail on top of a shell rejection mechanism of a
rifle.
[0003] 2. Description of Related Art
[0004] A great number of patents about telescopic sight mounts are
disclosed. For example, U.S. Pat. No. 4,021,954 discloses a
telescopic sight mount which is characterized by that a bracket
secured around a rifle barrel, a sight adapter axially slidably
mounted to an upper portion of the bracket, a first tongue member
lockingly engaged with a telescopic sight, and a second tongue
member lockingly engaged with the bracket.
[0005] Thus, continuing improvements of telescopic sight mount are
constantly sought.
SUMMARY OF THE INVENTION
[0006] It is therefore one object of the invention to provide a
sight mount for securing a telescopic sight to a mounting rail on
top of a shell rejection mechanism of a rifle, comprising a bracket
formed of thermoplastics and comprising a plurality of first
threaded holes, a plurality of second threaded holes perpendicular
to and offset with respect to the first threaded holes, a
lengthwise bottom recess distal a top of the bracket and being
slidably mounted to the mounting rail, and a lengthwise groove in
the recess being proximate to the top of the bracket; a plurality
of fasteners for securing the bracket to the telescopic sight by
driving through the first threaded holes into the telescopic sight;
and a plurality of fastening assemblies for securing the bracket to
the mounting rail by driving through the second threaded holes.
[0007] The above and other objects, features and advantages of the
invention will become apparent from the following detailed
description taken with the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
[0008] FIG. 1 is a perspective view of a sight mount according to a
first preferred embodiment of the invention;
[0009] FIG. 2 is an exploded view of the sight mount to be
assembled with a telescopic sight;
[0010] FIG. 3 is a perspective view of the sight mount mounted on
mounting rails on top of a rifle barrel and the telescopic sight
mounted on the sight mount;
[0011] FIG. 4 is an exploded view of a sight mount according to a
second preferred embodiment of the invention; and
[0012] FIG. 5 is a perspective view of the sight mount of FIG. 4
mounted on mounting rails on top of a rifle barrel and the
telescopic sight mounted on the sight mount.
DETAILED DESCRIPTION OF THE INVENTION
[0013] Referring to FIGS. 1 to 3, a telescopic sight mount 1 in
accordance with a first preferred embodiment of the invention
comprises the following components as discussed in detail
below.
[0014] A bracket 2 is made of thermoplastics (i.e., having a
limited compressibility) and is an elongated block having a
cross-section of rectangle. The bracket 2 comprises two spaced,
vertical first threaded holes 22, two spaced, horizontal second
threaded holes 23 offset with respect to the first threaded holes
22 (i.e., not intersecting), a lengthwise recess 20 on bottom, the
recess 20 having two opposite dovetailed groove sides, and a
lengthwise groove 21 oriented vertically in the recess 20, the
groove 21 having a rectangular section in each of vertical and
horizontal directions. The second threaded hole 23 is discontinuous
because it is disrupted by a joining portion of the groove 21 and
the recess 20 (see FIG. 1).
[0015] An individual may place the bracket 2 on a mounting rail 40
projecting out of top of a shell rejection mechanism 41 of a rifle
4 by sliding the recess 20 along the mounting rail 40. The mounting
rail 40 has two tongue sides. Hence, the recess 20 and the mounting
rail 40 are engaged together in a tongue and dovetail fashion.
[0016] Four fastening assemblies in which each of a first group of
two fastening assemblies is a hex socket screw 31 adapted to drive
through the second threaded holes 23 into two threaded holes 50 on
bottom of a telescopic sight 5 for mounting the telescopic sight 5
on top of the bracket 2. Each of a second group of two fastening
assemblies comprises a hex socket screw 31 adapted to drive through
the first threaded hole 22 (over the mounting rail 40) and a nut 32
at the other side of the bracket 2 by means of a hex wrench. An
individual may put a washer 33 and a wing nut 34 on a portion of
the hex socket screw 31 projecting out of the other side of the
bracket 2, and then hold and turn two opposite wings 340 of the
wing nut 34 to clampingly fasten the bracket 2 on the mounting rail
40.
[0017] Referring to FIGS. 4 and 5, a telescopic sight mount in
accordance with a second preferred embodiment of the invention is
shown. The characteristics of the second preferred embodiment are
detailed below.
[0018] The bracket 2 is separated into a large first part 24 and a
small mating second part 25. On the other side of the first part 24
there are provided with two circular cavities 26 each at the mouth
of the second threaded hole 23. The cavity 26 is shaped to receive
both the nut 32 and the washer 33 so as to form a flat surface on
the other side of the first part 24.
[0019] While the invention herein disclosed has been described by
means of specific embodiments, numerous modifications and
variations could be made thereto by those skilled in the art
without departing from the scope and spirit of the invention set
forth in the claims.
