Description
[0001] The current application claims a priority to the U.S.
Provisional Patent application Ser. No. 62/008,201 filed on Jun. 5,
2014.
FIELD OF THE INVENTION
[0002] The present invention relates generally to firearm
attachments. More specifically, the present invention is a firearm
slide attachment that is intended to allow a user to more easily
rack the slide of a firearm to which the present invention is
attached.
BACKGROUND OF THE INVENTION
[0003] Human history is riddled with examples of armed conflict
where two or more factions have attempted to subjugate, conquer,
eliminate, or free another faction. This armed conflict is known
colloquially as war, and can occur for an extremely wide variety of
reasons. The propensity of humankind to solve disputes through war
has led to ever advancing development of defense technologies which
are designed to allow their users to survive encounters with
hostile combatants. There are many important milestones and
technological breakthroughs within the field of defense technology,
however, one of the most important developments in the last several
centuries has been the invention of the firearm. Firearms have
revolutionized the way defenses are approached, as they allow for a
user to neutralize threats at long range when compared to more
ancient defense technologies such as spears and bow and arrows.
Additionally, firearms tend to be more efficient in the
neutralization of the threat, whereas a spear or arrow may leave
the threat partially operational while a bullet from a firearm will
likely outright eliminate or incapacitate the threat.
[0004] Most modern firearms are carried and operated by individuals
and are consequently known as small arms. Other heavier firearms
which are operated by crews or mounted on vehicles are known as
heavy weapons, crew-served weapons, or infantry support weapons.
The most important defining characteristic of a small arm in
comparison to other firearms is the fact that a small arm can be
carried and fully operated by a single individual; thereby
providing personal threat neutralization capabilities to that user.
As a result of the fact that small arms can be carried and operated
by a single individual, they are also extremely popular amongst
private citizens for the purposes of hunting, recreation, and
self-defense. Pistols are a very common type of small arm among
private citizens, as they are ideal for self-defense.
[0005] Safe operation of a pistol is a skill that can be learned by
nearly any person, thus further increasing the popularity of
pistols for self-defense purposes. Unfortunately, there is at least
one physical barrier which can prevent some people from
successfully operating a pistol. This barrier is the slide of the
pistol. In operation, nearly all firearms require that the user
chamber a round by racking the slide when a loaded magazine is
initially placed into the pistol. The action of racking the slide
requires the user to grip the sides of the slide and either push or
pull the slide backwards, thereby working the action of the firearm
and causing a round to be chambered and the firing pin to be
cocked. The action of racking the slide can require a great deal of
force, particularly with certain models of firearms. Some people
who would like to own a particular firearm may lack the hand
strength to successfully and reliably rack the slide when they
operate the firearm. This can be dangerous for the user, as
improper handling of the firearm could result in accidental
discharge. Furthermore, failure to rack the slide successfully in a
dangerous situation could result in injury to the user as they may
be unable to defend themselves properly. It is clear that there is
a need for an apparatus which can increase the ease with which a
user can rack the slide of a firearm, particularly pistols.
[0006] Therefore, it is an object of the present invention to
introduce a firearm slide attachment that is intended solely for
use in racking the slide of a firearm. It is an object of the
present invention to be attachable to the slide of a firearm
without the use of any tools, thus making it quick and easy to use
in almost any situation. It is an object of the present invention
to make use of the gripping grooves found on almost all pistol
slides to interlock the present invention with the slide such that
force applied to the present invention is translated to the slide
without slippage. The present invention provides vastly improved
gripping structures which give the user a mechanical advantage when
racking the slide, thus making it possible for a user with less
hand strength to easily rack the slide of a firearm which they
otherwise would have difficulty with. Thus, the present invention
provides great advantage for owners of firearms who wish to more
easily rack the slides of said firearms.

DETAIL DESCRIPTIONS OF THE INVENTION
[0022] All illustrations of the drawings are for the purpose of
describing selected versions of the present invention and are not
intended to limit the scope of the present invention.
[0023] The present invention is a firearm slide attachment that can
easily be attached to or detached from the slide of a firearm. The
present invention does not require the use of any tools when it is
attached to the firearm, and its preferred embodiment is designed
specifically for use with pistols. The primary purpose of the
present invention is to interface with the rear portion of the
slide and provide a user with a much better structure to grip and
rack the slide to chamber a round. The present invention is
intended only to be used to rack the slide, and should be removed
prior to firing the weapon, as the rapid recoil motion of the slide
could dislodge the present invention if it were left in place.
Furthermore, the present invention is intended to be compatible
with several different types of pistols manufactured by several
different companies. This enhances the utility of the present
invention by allowing it to be used with several different guns
instead of with only one.
[0024] In reference to FIG. 1, the present invention comprises an
attachment body 1, a plurality of interface protrusions 2, a first
grip 3, and a second grip 4. The attachment body 1 is the central
component of the present invention and supports the plurality of
interface protrusions 2, the first grip 3, and the second grip 4.
The attachment body 1 slips overtop of the slide of the firearm, as
depicted by FIG. 11-12, while the plurality of interface
protrusions 2 engage the grooves in the slide, such that when the
present invention is pulled backwards, the slide of the firearm is
pulled backwards as well, as shown in FIG. 13. The first grip 3 and
the second grip 4 provide an increased surface area that can be
gripped by the user as compared to the slide standalone, thus
allowing the user to more conveniently rack the slide.
[0025] In further reference to FIG. 1, the attachment body 1
comprises a bridge 11, a first wing 14, a second wing 15, and a
sight aperture 16. The bridge 11 comprises a proximal surface 12
and a distal surface 13; the proximal surface 12 and the distal
surface 13 being positioned opposite each other about the bridge
11, as depicted by FIG. 6-7. The proximal surface 12 is positioned
adjacent to the surface of the firearm when the present invention
is attached to the slide. Both the first wing 14 and the second
wing 15 are adjacently connected to the proximal surface 12,
wherein the first wing 14 and the second wing 15 are positioned
opposite each other across the bridge 11, as depicted by FIG. 2-3.
Together the bridge 11, the first wing 14, and the second wing 15
delineate a slide channel 17, which allows the present invention to
be fitted over top of the slide.
[0026] The positioning of the first wing 14 and the second wing 15
about the bridge 11 provides the attachment body 1 with a general
U-shape, wherein the first wing 14 and the second wing 15 engage
opposite sides of the slide. The exact angle at which the first
wing 14 and the second wing 15 intersect the bridge 11 may vary
depending on the specific firearm for which the present invention
is intended, as the slides of different firearms come in many
shapes and sizes. Depending on the material used to construct the
attachment body 1, it is also possible for the attachment body 1 to
be flexible, wherein the exact shape and size of the attachment
body 1, and in turn the slide channel 17, is variable in order to
accommodate firearms of similar shape yet different size.
[0027] The present invention is intended to be placed over the rear
of the slide and it is well known that rear sights are present at
the rear of the slide on pistols, thus, the sight aperture 16 is
provided by the attachment body 1. In reference to FIG. 6-7, the
sight aperture 16 traverses through the bridge 11 from the proximal
surface 12 to the distal surface 13, providing a void in the bridge
11. The sight aperture 16 facilitates the mounting of the
attachment body 1 on the slide of the firearm by allowing the
attachment body 1 to fit around the sight of the firearm, such that
that the sight protrudes upwards through the attachment body 1, as
shown in FIG. 12-13. As such, the sight aperture 16 ensures that
the present invention can be placed in the optimal position at the
rear of the slide and used to rack the slide without interference
from the sight.
[0028] The sight aperture 16 is appropriately sized and spaced
depending on the firearm with which the present invention is to be
used. In the preferred embodiment of the present invention, the
sight aperture 16 is a rectangular slot that traverses across the
bridge 11 from the first wing 14 to the second sing. This
configuration of the sight aperture 16 provides a rear slot in the
bridge 11 that is adaptable to multiple firearms as the sight
aperture 16 can be fitted around sights with varying widths. In
other embodiments of the present invention, the sight aperture 16
may be positioned about the front of the bridge 11 or at a distance
between the front and back of the bridge 11.
[0029] The primary purpose of the plurality of protrusions is to
ensure that the present invention does not slip along the slide
when the present invention is pulled by the user into order to rack
the slide. Effectively, it is important that the present invention
is fixed relative to the slide of the firearm. The plurality of
protrusions is critical to fixing the attachment body 1 relative to
the slide, as the plurality of interface protrusions 2 interlocks
with the grooves commonly found at the rear of slides. As such, the
plurality of interface protrusions 2 is adjacently connected to
both the first wing 14 and the second wing 15, wherein the
plurality of interface protrusions 2 is positioned within the slide
channel 17, as shown in FIGS. 2-3 and FIG. 7.
[0030] Each of the plurality of interface protrusions 2 protrudes
out into the slide channel 17 by some distance, and into a groove
of the slide when the present invention is attached to the firearm.
Thus, the present invention is physically restricted from moving
along the length of the slide due to the interlocking between the
plurality of interface protrusions 2 and the grooves on the slide.
However, the use of the plurality of protrusions allows the present
invention to be readily detached from the firearm once the slide
has been racked. This allows the user to quickly transition from
the racking motion to a firing motion if desired. For safe
operation of the firearm, the present invention should be removed
before firing as the present invention could be dislodged and
become a projectile due to the rapid motion of the slide.
[0031] In reference to FIG. 7, the plurality of interface
protrusions 2 is arranged into a first distribution pattern 21 and
a second distribution pattern 22 in order to conform to the grooves
on both sides of the slide. The first distribution pattern 21 is
imposed on the first wing 14, dictating the position of each of the
plurality of interface protrusions 2 about the first wing 14,
wherein each of the plurality of interface protrusions 2 on the
first wing 14 is aligned with a groove on a first side of the
slide. Similarly, the second distribution pattern 22 is imposed on
the second wing 15, dictating the position of each of the plurality
of interface protrusions 2 about the second wing 15, wherein each
of the plurality of interface protrusions 2 on the second wing 15
is aligned with a groove on a second side of the slide.
[0032] The first distribution pattern 21 and the second
distribution pattern 22 can be symmetrical or asymmetrical
depending on the slide. For example, if the first side and the
second side of the slide are identical (i.e. the grooves on each
side are equally spaced and are of equal height, width, and depth),
then the first distribution pattern 21 and the second distribution
pattern 22 are symmetrical, as depicted by FIGS. 8A and 8B. If the
first side and the second side of the slide are not identical (i.e.
the grooves on each side are not equally spaced or are not of equal
height, width, and depth), then the first distribution pattern 21
and the second distribution pattern 22 are asymmetrical, as
depicted by FIGS. 9A and 9B. By engineering the first distribution
pattern 21 and the second distribution pattern 22 properly, the
present invention can also be designed to be utilized with several
different firearm models having commonly spaced/sized grooves along
the slide.
[0033] While the attachment body 1 and the plurality of interface
protrusions 2 provide a means for the present invention to engage
the slide, the first grip 3 and the second grip 4 provide the means
for exerting a force on the attachment body 1 to rack the slide. In
reference to FIG. 2-3, the first grip 3 is adjacently connected to
the first wing 14 opposite the slide channel 17, while the second
grip 4 is adjacently connected to the second wing 15 opposite the
slide channel 17. In this way, both the first grip 3 and the second
grip 4 provide a protrusion extending away from the attachment body
1 with which the user may engage in order to pull the attachment
body 1 backwards, and in turn the slide. The exact shape and size
of the first grip 3 and the second grip 4 may vary in different
embodiments of the present invention, however, the first grip 3 and
the second grip 4 should be designed with ergonomics in mind.
[0034] In the preferred embodiment of the present invention, the
first grip 3 and the first wing 14 delineate a first grip cavity 5.
In reference to FIG. 4, the first grip cavity 5 is formed by an
edge of the first wing 14, a pair of straight edges of the first
grip 3, and a curved edge of the first grip 3. The curved edge of
the first grip 3 is positioned opposite the edge of the first wing
14 along the pair of straight edge, and adjacent to the sight
aperture 16. The curved edge, in conjunction with the first grip
cavity 5, allows the user to more readily engage and pull on the
first grip 3, wherein the curved edge helps the first grip 3 better
conform to the user's finger. Furthermore, the first grip cavity 5
reduces material costs of the present invention in addition to
improved gripping mechanics.
[0035] Additionally, in the preferred embodiment, the first grip 3
comprises a first tapered section 31 and a first curved section 32.
In reference to FIG. 6, the first curved section 32 is positioned
adjacent to the sight aperture 16, while the first tapered section
31 is positioned adjacent to the first curved section 32 opposite
the sight aperture 16, wherein the first tapered section 31 tapers
away from the first curved section 32. Together, the first tapered
section 31 and the first wing 14 delineate the first grip cavity 5,
while the first curved section 32 provides a contoured surface that
extends and curves away from the attachment body 1. Furthermore,
the first curved section 32 is rounded to better conform to the
user's finger in addition to reducing material costs.
[0036] Similar to the first grip 3, in the preferred embodiment of
the present invention, the second grip 4 and the second wing 15
delineate a second grip cavity 6. In reference to FIG. 5, the
second grip cavity 6 is formed by an edge of the second wing 15, a
pair of straight edges of the second grip 4, and a curved edge of
the second grip 4. The curved edge of the second grip 4 is
positioned opposite the edge of the second wing 15 along the pair
of straight edge, and adjacent to the sight aperture 16. The curved
edge, in conjunction with the second grip cavity 6, allows the user
to more readily engage and pull on the second grip 4, wherein the
curved edge helps the second grip 4 better conform to the user's
finger. Furthermore, the second grip cavity 6 reduces material
costs of the present invention in addition to improved gripping
mechanics.
[0037] Additionally, in the preferred embodiment, the second grip 4
comprises a second tapered section 41 and a second curved section
42. In reference to FIG. 6, the second curved section 42 is
positioned adjacent to the sight aperture 16, while the second
tapered section 41 is positioned adjacent to the second curved
section 42 opposite the sight aperture 16, wherein the second
tapered section 41 tapers away from the second curved section 42.
Together, the second tapered section 41 and the second wing 15
delineate the second grip cavity 6, while the second curved section
42 provides a contoured surface that extends and curves away from
the attachment body 1. Furthermore, the second curved section 42 is
rounded to better conform to the user's finger in addition to
reducing material costs.
[0038] The first grip 3 and the second grip 4 are rigid members, as
both must be able to sustain sufficient force in order to rack the
slide. However, in some embodiments of the present invention it is
possible for a pliable material to be applied to the first grip 3
and the second grip 4 in order to provide a cushioned surface for
the user to grip. The pliable material allows the user to more
comfortably grip the present invention, while maintaining the
rigidity of the first grip 3 and the second grip 4. Additionally,
the pliable material may be used to provide the first grip 3 and
the second grip 4 with a higher coefficient of friction, thus
decreasing the chance of slippage between the user's fingers and
the first grip 3 and the second grip 4.
[0039] The present invention may also further comprise a gripping
pad 7 in some embodiments. The gripping pad 7 is made from a
material that is flexible, compressible, and has high coefficient
of friction. In reference to FIG. 10, the gripping pad 7 is
adjacently connected to the attachment body 1, wherein the gripping
pad 7 is positioned within the slide channel 17 and is contoured
about the plurality of interface protrusions 2. The gripping pad 7
is intended to help increase the friction between the present
invention and the slide, thereby decreasing chance of slippage
between the present invention and the slide. The exact shape,
thickness, and material composition of the gripping pad 7 may vary
between different embodiments.
[0040] Although the invention has been explained in relation to its
preferred embodiment, it is to be understood that many other
possible modifications and variations can be made without departing
from the spirit and scope of the invention as hereinafter
claimed.
