CROSS-REFERENCE TO RELATED APPLICATIONS
FIELD OF THE INVENTION
This application claims the priority date of the provisional application entitled REMOVABLE HAND PROTECTOR FOR SEMI AUTOMATIC PISTOLS filed by Mike Gibson Manufacturing Inc. on Jan. 9, 2007, with application Ser. No. 60/879,643.
- BACKGROUND OF THE INVENTION
The invention relates to generally to an apparatus for use with a handgun, and more particularly to safety device for attachment to a handgun grip for use with semi-automatic pistols.
Semi-automatic pistols (herein after referred to simply as “pistols”) have an inherent danger related to how they are held when they are fired. Without coaching as to the proper way to grip a pistol, it is entirely possible that the inexperienced shooter will be injured the first time they fire the pistol.
More specifically, a pistol is comprised of three primary components:
- 1. the Frame (which includes the grip portion of the pistol),
- 2. the Barrel, and
- 3. The Slide.
The frame does not move, and the barrel only moves a very minimal amount, but the slide moves back and forth over the top of the frame. At the extreme point of movement, the slide extends past the back of the grip approximately 2 inches. This 2″ dimension varies between manufacturers, models, and calibers, but in all cases it is enough to cut two slices in the top of the shooters weak hand thumb.
Pistols are often held incorrectly by beginning and inexperienced shooters, and there are two primary methods of doing it wrong.
- 1. The strong hand (holding the grip) is cradled in the other hand, much like a tea cup on a saucer (Teacup Grip);
- 2. The weak hand grasps the strong hand, with the weak thumb crossing the strong thumb. (Overlap Grip).
The safety issue occurs in the second scenario. As the slide activates, (which occurs in about 0.15 seconds), it moves back from the frame very quickly, and then quickly returns to its default position on the frame, being back by the impact of the firing cartridge, and being driven forward by a spring. This reciprocating action causes the rails on the bottom of the slide to make two quick slashes across the top of the weak hand thumb. Depending on how high up the weak thumb was, at the least, first aid will be required, and in the worst case, professional medical attention will be required.
- SUMMARY OF THE INVENTION
Many pistols now come from the factory with a device commonly known as a “beavertail”, which minimizes the possibility of injury resulting from holding the pistol incorrectly. In the case of Glock brand pistols, the integral beavertail is minimal, but it does help to a small extent. If the shooter has particularly large hands, or is a competitive shooter, the risk of injury is still great, and in some cases, it is certain, if the shooter isn't always cognizant of exactly how the pistol is being held. This poses a danger for competitive shooters also, since they tend to hold the pistol “higher”, which increases the possibility and likelihood of the injury.
The pistol attachment of the invention may be applied to many different brands of pistols, and serves to extend to the rearward the factory grip shape of pistols by ½″ to ¾″, to the point that any slide related injury is a virtual impossibility.
The device is a removable device, most commonly injection molded plastic, (or hand molded plastic), and is held on the pistol grip with adhesive grip tape, or with a piece of rubber tube. With this removable feature, if the user doesn't like it, it can easily be removed with no damage to the original pistol configuration. It could also be manufactured of metal or other material, and it could be permanently applied, if that is what the user wanted.
The shooting aid of the invention is generally v-shaped, with a first end and a second end. The two ends of the “v” do not have to be the same length. The device includes a first side and a second side. The first side forms the outside surface of the “v,” and is generally concave in shape. It is shaped to form a close engagement with the back of the handle or grip of a handgun, and would have surface details congruent with a particular handgun. The second side forms the inside surface of the “v” and is designed for engagement by a user's hand. The second side of the pistol attachment is generally convex and generally parallels the concave surface of the first side. The device is configured to be placed on the back side of the pistol grip of a handgun, with the first end of the attachment extending partially down the pistol grip, and with the second end of the “v” being positioned generally parallel to and below the path of the slide of the pistol. The first end forms an acute angle with the second end.
The device is attached to the grip of the pistol preferably by a tape which is adhesive on one side, and provides a good gripping surface on the other side. A sandpaper type surface may be used, or the gripping surface of the tape can also be a rubberized surface that has a good grip to the user, or any surface which provides good adhesion to the grip of the handgun as well as the desired feel by the user can be used at part of the tape.
Other forms of attachment can be used, such as by a wide rubber loop, One or more smaller diameter rubber loops, a layer of adhesive, or by screws.
The device is preferably made of an injection molded plastic such as Kydex, or other high impact or high density plastics. The device can also be made of other materials such as metal, including aluminum, steel, titanium, or other metals which have the required characteristics of rigidity.
The first end of the device is designed to extend from two-thirds to one-half of the distance of the length of the grip handle.
The purpose of the Abstract is to enable the public, and especially the scientists, engineers, and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection, the nature and essence of the technical disclosure of the application. The Abstract is neither intended to define the invention of the application, which is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.

FIGS. 1-4 show several preferred embodiments of the invention. FIG. 1 shows the shooting aid 10 of the device. The device 10 is generally V-shaped with the outside surface of the “V” shown as 34 in FIG. 1, with the inside surface of the “V” shown as 38. The outside surface of the “V” 34 is a concave surface 32 and the inside surface of the “V” is a convex surface 36. Shown in FIG. 1 is the first end 24, the second end 26, the first side 28, and the second side 30. The first end 24 is made to be mounted adjacent to the rear of the handle or grip of a selected handgun. The second end 26 is configured so that when the device is mounted on a handgun, the first side 28 adjacent to the second end 26 will be generally parallel to the bottom of the underside of the handgun slide 40. When mounted in this configuration, the device will prevent a user's hands from intersecting the path of movement 22 of the slide 16 of a handgun. Shown in FIG. 1 is a positioning wall, 48 which includes a pocket, 50. The positioning wall 48 and the pocket 50 are configured to fit onto the rear profile of a handgun such as a Glock 40 caliber or other handguns. FIG. 1 shows the pocket, 50, and FIG. 2 shows, in dotted line, where the rear feature 54 of the handgun 12 fits into the pocket 50 of the handgun.
FIG. 2 shows the device 10 mounted on a handgun 12. The handgun includes a frame 14, a slide 16, a grip 18, and a barrel 20. The path of movement 22 of the handgun is show in FIG. 4. Returning to FIG. 2, the shooting aid 10 is shown with one possible type of attachment, by use of an adhesive layer 52 between the grip of the handgun and the shooting aid 10.
FIG. 3 shows an embodiment of the invention in which the device 10 is attached to the hand gun 12 by attachment means 42 which in this case is tape 44. This tape is preferably adhesive on one side and has a gripping surface on the other side. The gripping surface can be in the form of something like sandpaper, or can also be in the form of a rubberized surface which has good gripping characteristics.
FIG. 4 shows the device 10 using as an attachment means 42, a band of elastic 46. Other attachment means can include use of screws or bonding to the material of the pistol grip, such as by sonic bonding, use of an epoxy or other hardening material, or other conventional attachment means.
The device of the invention is configured so that it extends the tail end of the handgun frame rearward from the grip about three-quarters to one inch. The first side of the device is made to cover from one-half to three-quarters of the backside of the pistol grip, and to have the concave surface of the first side have a close and accurate contact with the rear of the handgun.
One type of adhesive tape which can be utilized is tape which is utilized to affix a sandpaper-like gripping surface to objects such as skateboards.
