Description
[0001] The present invention relates in generally to a handguns,
more specifically to a handgun spring and guide rod assembly.
[0002] The guide rod assembly is typically a cylindrical rod that
is provided to optimize the performance of recoil springs through
additional support and spring alignment. The guide rod controls how
the pistol's slide functions. Thus by controlling the spring, the
guide rod helps position the recoil spring during the firing cycle.
Some handguns feature a capture spring which is an assembly of the
guide rod and spring as a unit. In essence the guide rod then
maintains the recoil spring itself and in turn enhances the slide
return.
[0003] Typically, the guide rod is inserted into the slide of a
handgun by pinching the rear portion of the rod forward and into of
the slide. An indent on the barrel lug, also present within the
slide, provides the position for securing the guide rod inside the
handgun slide. At this point, the flanged rear end of the guide rod
will sit securely on the semi-circular portion on the handgun
frame, and the lower notch on the barrel lug.
[0004] The design of the spring guide rod is such that upon
insertion into the slide, it sits securely against the barrel lug
notch, and in contact with the semi-circular portion on the frame.
The issue comes when the user "racks the slide" to allow the fire
arm to be fired. When this happens, the spring guide rod disengages
from the barrel notch and sits firmly in the semi-circular portion
of the handgun frame. Therefore, a small distance between the guide
rod and the barrel is created. Although most users will not notice
an issue because this operation happens internally and is not
readily apparent through inspection, creating a secure fit between
the barrel, the handgun frame, and the recoil spring guide rod is
important for increased accuracy on a round is fired down range.
Additionally, due to the design of the barrel, the barrel has an
upper and a lower notch. If the guide rod is installed incorrectly
onto the barrel notch, the guide rod might not make adequate
contact with the handgun frame and will eventually break.
[0005] Therefore, it should be apparent that there is a need for an
apparatus which provides a means for securing the spring guide rod
into the frame while maintaining contact with the barrel of the
handgun.
SUMMARY
[0006] Accordingly, it is an object of the present invention
provide a handgun guide rod and more particularly to a guide rod
which provides maximum contact points when installed into the
handgun. The guide rod functions as the controlling mechanism by
which the recoil spring is positioned and guided while the handgun
slide reciprocates prior to, during, and after the discharge of a
round.
[0007] Directed towards Glock style handguns and not limited
herein, these handguns utilize a guide rod composed of a single
cylindrical rod with a recoil spring permanently affixed on the
rod. These guide rods feature a front end and a rear end flange
which is a flat circular surface. The frame of the handgun features
a semicircular portion by which the guide rod makes contact with
when the handgun slide is racked. Prior to racking the slide, the
barrel of the handgun, which features an upper and lower notch
provide a contact surface for the guide rod. Once the guide rod is
racked, the circular rear portion disengages contact with the
barrel notch and is then secured by the semicircular portion of the
handgun frame. Due to this design, only half of the guide rod
circular rear flange is in contact at any given point in time
during operation of the handgun.
[0008] While the guide rod is secured, it is only partially
secured, and can flex. Thus flexion creates two problems. The first
is that the guide rod is much more susceptible to bending and hence
breaking. The second is that this flexion reduces overall
components rigidity which is detrimental to accuracy.
Thus, increasing the contact surfaces between the guide rod,
handgun frame and the barrel, an improved guide rod design can
mitigate both the probability of handgun failure due to guide rod
breakage as well as improves the accuracy of the handgun due to
rigidity of the aforementioned internal components. This is
accomplished by an improved guide rod featuring a circular rear
flange, similar to the original guide rod, but with a semicircular
lip protruding from the circular rear flange.

DETAILED DESCRIPTION OF DRAWINGS
[0016] The present invention is directed towards a recoil spring
guide rode, and more specifically to a recoil spring guide rod with
unique features, herein. The following descriptions are set forth
and have been assigned numerical designations to enable the reader
to understand the reasoning behind and the application of the
present invention. These, as well as other features of the present
invention, will become more obvious when taken with reference to
the drawings.
[0017] FIG. 1 is an illustration of a handgun frame 100. The
semicircular engagement portion 103 by which a recoil guide spring
engages upon racking the slide of the handgun is also shown.
Normally, this engagement portion 103 will provide the only point
of contact for a guide rod when the firearm is racked and ready to
fire. FIG. 2 is an illustration of the barrel 200, and features an
upper notch 203, which is also shaped as a semicircle, and a lower
notch 201 which provides engagement for components unrelated to
this invention.
FIG. 3 is an exploded illustration of the present invention showing
its screw 307, bushing 305, and guide rod 300. Positioning the
bushing 305 on the end opposite the flange 301 and insertion of the
screw 307 into the hollow cylindrical body of the guide rod 300
provides a means for mitigating the movement of a spring 304 away
from the body of the guide rod 300. This is further shown in and
should be apparent upon inspection of FIG. 4. FIG. 4 also shows the
essential feature of the guide rod 300 where the flange 301 is a
circular surface with a semicircular portion, the flange lip 302,
protruding and extending away from the body of the guide rod 300.
The flange 301 is designed to sit and position the guide rod 300 at
the handgun frame semicircular portion 103, as shown in FIG. 5.
Notice that the flange lip 302 extends away from the guide rod 300,
and over the semicircular engagement portion 103 on the handgun
frame 100. A partial view of the present invention installed onto
the barrel upper notch 203 is shown in FIG. 6. Notice that the
flange lip 302 at the rear end of the guide rod 300 is shown in
engagement with the barrel 200. Recoil spring 304 is also present
and secured in place within the handgun slide 400. Finally, FIG. 7
illustrated the present invention installed into the handgun frame
100, and handgun slide 400 also present in a racked position. In
this configuration, the flange lip 302 is in engagement with the
barrel 200 at the upper notch 203 and also in engagement with the
handgun frame 100. Recoil spring 304 is also shown positioned
around the guide rod 300.
