Description
- This application claims priority to U.S. Provisional Patent Application Ser. No. 61/962,825 entitled Kohel Safety Lock filed on Nov. 18, 2013, which is incorporated herein by reference.
- In the United States there are hundreds of unintentional firearm injuries that lead to death each year. Sometimes the unintentional firearm injuries are caused by a child finding a loaded firearm and using the loaded firearm as a toy. In some situations, an adult unintentionally fires a firearm, and the result is often a firearm injury resulting in the death of the person struck by the bullet from the firearm.
- Many firearms come with built-in safety mechanisms. The safety mechanisms typically are used to prevent unintentional discharge of the firearm during handling. Often the safety mechanism is an external safety, which allows the user to toggle a switch from “on” to “off” in order to fire the firearm or from “off” to “on” in order to store or handle the firearm when not being used for firing.
- The present disclosure can be better understood with reference to the following drawings. The elements of the drawings are not necessarily to scale relative to each other, emphasis instead being placed upon clearly illustrating the principles of the disclosure. Furthermore, like reference numerals designate corresponding parts throughout the several views.

FIG. 1 depicts anexemplary firearm 100 in accordance with an embodiment of the present disclosure. The firearm shown inFIG. 1 is a revolver; however the present disclosure is not limited to revolvers. In this regard, other types of firearms are possible in other embodiments of the present disclosure. - The
firearm 100 comprises abarrel 102, aframe 104, and agrip 106. Additionally, thefirearm 100 comprises ahammer 103, acylinder 101, and atrigger 105.FIG. 2 is a cross-sectional view of thecylinder 101 showing a plurality ofchambers 200 in which bullet cartridges are inserted. - With reference to
FIG. 1 , during ordinary operation, a marksman loads bullet cartridges (not shown) in the chambers 200 (FIG. 2 ) of thecylinder 101. To fire a bullet (not shown) contained within one of the cartridges, a marksman swings thecylinder 101 out and loads thechambers 200 with individual bullet cartridges. - The marksman then closes the
cylinder 101 so that it is coupled with theframe 104 and is stationary. The marksman cocks thehammer 103 back to line up a bullet cartridge between thehammer 103 and thebarrel 102. The marksman pulls thetrigger 105 while grasping thegrip 106. - Upon pulling the trigger,
hammer 103 is released, and via a spring mechanism (not shown), the hammer is thrown forward thereby striking the bullet cartridge contained within thechamber 200. Propellant (not shown) within the bullet cartridge is ignited, and the bullet is propelled through the barrel, thereby sending the bullet to a target (not shown). - An
exemplary safety lock 300 in accordance with an embodiment of the present disclosure is shown inFIG. 3 . Thesafety lock 300 comprises acylindrical body 306. Fitted over thecylindrical body 306 is an O-ring 305. The O-ring 305 may be made of any type of flexible material that when force is applied to the O-ring 305. In one embodiment, the O-ring 305 is made of neoprene; however, the O-ring 305 may be composed of other types of material that are flexible over a wide temperature range. - On each end of the
safety lock 300 is a threadedbore bores conical openings safety lock 300 depicted inFIG. 3 . Note that theconical openings FIG. 3 . The threadedbores safety lock 300 and not exhibit theconical openings - In one embodiment, the
safety lock 300 is made out of a light weight material so that thesafety lock 300 is retained in the revolver 100 (FIG. 1 ) when therevolver 100 is not being used. Notably, thesafety lock 300 may be comprised of a nylon material or aluminum, for example. -
FIG. 4A is a cut-away view of therevolver 100 as shown inFIG. 1 having thesafety lock 300 inserted therein to prohibit movement of thecylinder 101. Note that if the cylinder is prohibited from rotating, a bullet cartridge is not loaded in thechamber 200 for firing. - The
barrel 102 comprises acylindrical passage 401 through which a bullet may travel for projection from thechamber 200 during ordinary operation. However, in accordance with the present disclosure, asafety lock 300 is inserted within thecylindrical passage 401 until a portion of thesafety lock 300 is situated within thechamber 200 and a portion remains extended into thecylindrical passage 401 of thebarrel 102. - Note that a diameter of the
safety lock 300 is slightly less than a diameter of thecylindrical passage 401 of thebarrel 102. The slight difference in diameters allows thesafety lock 300 to be inserted into thecylindrical passage 401. The O-ring 305 deforms as thesafety lock 300 is inserted into thecylindrical passage 401. Deformation of the flexible O-ring 305 provides a retaining force against the wall of thecylindrical passage 401. The force exerted by the flexible O-ring 305 retains thesafety lock 300 within thecylindrical passage 401. - In one embodiment, the
safety lock 300 is longer than the length of thechamber 200. When thesafety lock 300 is longer than the length of thechamber 200, an end portion of thesafety lock 300 fits into a portion of thechamber 200, and the opposite end portion of thesafety lock 300 extends into the barrel. Thus, thecylinder 101 is prohibited from rotating and loading a bullet cartridge into the chamber. - Note that the
safety lock 300 is shown as inserted into a revolver. In particular, therevolver 100 depicted is a .38 Special revolver. Note that thesafety lock 300 may be used with other similar weapons. For example, thesafety lock 300 may be used with a .357 Magnum revolver. - This is further shown with reference to
FIG. 4B .FIG. 4B shows a cross-sectional view of thecylindrical passage 401. Thesafety lock 300 is inserted into thecylindrical passage 401. Thesafety lock 300 has a diameter d1, which is slightly less than a diameter d2 of thecylindrical passage 401 thereby allowing thesafety lock 300 to be inserted into thecylindrical passage 401. When thesafety lock 300 is inserted into thecylindrical passage 401, the deformable O-ring 305 is flexible enough to allow insertion but further exerts a force outwardly on awall 408 of thecylindrical passage 401 as shown byreference arrows ring 305 retains thesafety lock 300 within thecylindrical passage 401. -
FIG. 5 shows anexemplary insertion tool 500 for inserting the safety lock 300 (FIG. 3 ) into thecylindrical passage 401. Theinsertion tool 500 comprises arod body 503. One end of theinsertion tool 500 comprisesthreads 501. At the other end of theinsertion tool 500 is acap 502, which ensures that the marksman can easily grasp theinsertion tool 500. -
FIG. 6 shows theinsertion tool 500 coupled to thesafety lock 300. In this regard, thethreads 501 of the insertion tool threadedly couple to the threadedbore 301. Note that theinsertion tool 500 may also be threadedly coupled to the threadedbore 303. When theinsertion tool 500 is coupled to thesafety lock 300, thesafety lock 300 may be inserted into the cylindrical passage 401 (FIG. 4A ) of the barrel 102 (FIG. 4A ). -
FIG. 7 shows thesafety lock 300 threadedly coupled to theinsertion tool 500. Thesafety lock 300 is inserted into the cylindrical passage 401 a pushed through thecylindrical passage 401 in a direction indicated byreference arrow 700 by pushing theinsertion tool 500 in the direction indicated byreference arrow 700. Thesafety lock 300 is pushed through thecylindrical passage 401 until it is partially within thechamber 200, as shown with reference toFIG. 8 . - In
FIG. 8 , thesafety lock 300 is inserted through thecylindrical passage 401 until at least a portion of thesafety lock 300 is within thechamber 200. As described hereinabove, the O-ring 305 retains thesafety lock 300 within thecylindrical passage 401 once it is inserted. - When the
safety lock 300 is fully or partially (as shown inFIG. 8 ) within thecamber 200, a marksman will be unable to pull thehammer 103 back to load a bullet cartridge within thechamber 200. In this regard, thesafety lock 300 prohibits thecylinder 101 from rotating to load another bullet cartridge. - Once the
safety lock 300 is within thechamber 200, the marksman may unscrew and therefore decouple theinsertion tool 500 from thesafety lock 300. Once theinsertion tool 500 is decoupled from thesafety lock 300, the marksman may pull theinsertion tool 500 from thecylindrical passage 401 in a direction indicated byreference arrow 801 leaving thesafety lock 300 within thechamber 200. - Notably, when the marksman is ready to use the
revolver 100, the marksman may remove thesafety lock 300 from thechamber 200. In this regard, the marksman inserts theinsertion tool 500 into thecylindrical passage 401. The marksman screws thethreads 501 into the threaded bore 301 to couple theinsertion tool 500 to thesafety lock 300. Once theinsertion tool 500 is coupled to thesafety lock 300, the marksman pulls theinsertion tool 500 from thecylindrical passage 401 in the direction indicated byreference arrow 801. -
FIG. 9 shows another embodiment of thesafety lock 300 as used in conjunction with arevolver 100 having abullet cartridge 900 contained with thechamber 200. In this regard, thesafety lock 300 is inserted into thecylindrical passage 401 of thebarrel 402 as described with reference toFIGS. 7 and 8 . - However, in the embodiment shown in
FIG. 9 , thebullet cartridge 900 is in thechamber 200. When thebullet cartridge 900 is within thechamber 200, a smaller portion of thesafety lock 300 may fit into thechamber 200 as opposed to when there is nobullet cartridge 900 in thechamber 200. However, thesafety lock 300 behaves in essentially the same manner. - Notably, when the
safety lock 300 is inserted within thechamber 200 when there is abullet cartridge 900 also in thechamber 200, thesafety lock 300 also prohibits the marksman from actuating thehammer 103. If thehammer 103 is not actuated, the marksman cannot pull thetrigger 105. Thus, thesafety lock 300 prohibits thefirearm 100 from being fired.
