Description

313892/4 A RIFLE SAFETY DEVICE FIELD OF THE INVENTION

[001] The present invention relates to firearms, in particular a safety device for a rifle.

BACKGROUND OF THE INVENTION

[002] Security and military systems a bullet the world use non-automatic safety devices that provide a partial response to the prevention of unwanted bullet emissions (firing); however, they have several operational and safety shortcomings.

[003] Typically rifles use a plastic dummy bullet in the chamber that is ejected when cocking the rifle. If a dummy bullet is not being used, there is no indication to the soldier if a bullet is in the chamber or not, and this could be clearly dangerous. The dummy bullet has a protrusion on the side, that the shooter can see, and so he knows that the dummy bullet is there; and a string is tied to the dummy bullet to help it not get lost when the dummy bullet is ejected, prior to firing a real bullet.

[004] However, there are drawbacks to this dummy bullet: (1) sometimes the dummy bullet is not properly inserted, or the tooth of the cocking assembly bolt does not engage properly with the dummy bullet, and the bullet does not eject upon cocking the rifle. This wastes time in potentially critical situations and usually requires two hands to fix. (2) When the standard dummy bullet is in the chamber, the ejection port cover is open, which allows dust/dirt to enter the ejection port and the cocking assembly, which often causes a bullet from the rifle’s magazine to get stuck. (3) when the rifle is carried, there is an indication to those who are looking, that the dummy bullet is in the chamber and the potential shooter cannot shoot until cocking the rifle. (4) The dummy bullet can easily get lost. Usually, the 313892/4 dummy bullet is connected to the riffle by a string, but since it`s not connected permanently, thus it can get lost. (5) Since it is not permanently connected to the rifle, the soldier can take it out, and compromise the safety of the riffle.

SUMMARY OF THE INVENTION

[005] The invention is a safety device for rifles that replaces the ejection port cover of the rifle and replaces the dummy bullet by an integrated cover port and dummy bullet device.

[006] In accordance with examples of the rifle safety device (for a rifle with a bullet receiving chamber), the device includes (a) an ejection port cover; (b) a dummy bullet; and (c) a pulling element disposed within ejection port cover, wherein the dummy bullet is connected to the ejection port cover; the dummy bullet is pulled from the chamber by the pulling element; and the dummy bullet is removed from the ejection port when the ejection port cover opens.

[007] In some examples, the pulling element is a spring. In some examples, the pulling element is an elastic. In some examples, the dummy bullet has a forward position and a rearward position. In some examples, the pulling element moves the dummy bullet from the forward position to the rearward position. In some examples, the pulling element is in a stretched position when the dummy bullet is in the chamber. In some examples, the ejection port cover has a transparent window. In some examples, the ejection port cover is of a non-standard color or shape to indicate that a non-standard ejection port is being used.

[008] In some examples, the dummy bullet is connected to the ejection port cover via a mechanical linkage mechanism including a linkage and a connecting rod. In some examples, the connecting rod is held within a protrusion, near or at, the rear of the dummy bullet, at a side facing the ejection port cover. In some examples, the linkage slides forward and rearward within a slot thereby allowing the dummy bullet to slide between a forward position in the chamber and a retracted position into ejection port. In some examples, the connecting rod rotates 313892/4 within the linkage. In some examples, at a front of the ejection port cover is a front stop; and at the rear of the ejection port cover is a rear stop.

[009] The safety device is mounted on an existing rifle in place of the ejection port cover and a separate dummy bullet. This mounting can be done by the manufacturer of a new rifle, or on existing riffles. This mounting is very easily done and addresses a number of shortcomings of the typical safety device.

[010] Both the existing and present safety devices are designed to ensure that there is no bullet in the chamber by a dummy bullet. In the existing device, the dummy bullet is pulled back and ejected by the cocking assembly. In the present invention, the dummy bullet is attached to the ejection port cover, and when the cocking assembly is retracted prior to firing, the dummy bullet is pulled back out of the chamber by a pulling element (e.g. spring, elastic, and the like) of the safety device and enters the ejection port. The dummy bullet then exits the ejection port by the automatic opening of the ejection port cover.

[011] Advantages of the present device include at least one of the following: (1) due to the integration of the dummy bullet and ejection port cover, the cover remains closed, thereby preventing dust from entering prior to firing; (2) because removal of the dummy bullet is not released by the cocking assembly, rather by a pulling element (e.g. spring, elastic, and the like), the dummy bullet does not get caught up with the cocking assembly, in particular the back end of the dummy bullet; (3) the dummy bullet is removed by the ejection port cover, not by the cocking assembly, and remains connected to the ejection port cover – it does not “fall away” (disconnect) from the ejection port, and so a string attached to the dummy bullet is not needed; (4) the dummy bullet cannot be lost; (5) the user cannot take the dummy bullet out, and (6) an observer cannot see if there is a real or dummy bullet in the chamber.

DETAILED DESCRIPTION OF EMBODIMENTS

[027] The invention may be more clearly understood upon reading of the following detailed description of non-limiting exemplary embodiments thereof, with reference to the drawings.

[028] The following detailed description of embodiments of the invention refers to the accompanying drawings referred to above. Dimensions of components and features shown in the figures are chosen for convenience or clarity of presentation and are not necessarily shown to scale. Wherever possible, the same reference numbers will be used throughout the drawings and the following description to refer to the same and like parts.

[029] Illustrative embodiments of the invention are described below. In the interest of clarity, not all features/components of an actual implementation are necessarily described.

[030] Fig. 1 shows a rifle as known in the prior art, with a chamber 100; an ejection port 102; a cocking assembly 104; and an ejection port cover 106. A standard dummy bullet 108, which is located in the chamber 100 prior to cocking the rifle (the dummy bullet is shown attached to a part of the rifle by a string 110). The dummy bullet 108 is moved by cocking the rifle to the ejection port 102 from which it is ejected by an assembly bolt 112 of the cocking assembly 104, when the rifle is cocked. The dummy bullet 108 is fully/entirely ejected from the ejection port 102 when the rifle is cocked. The ejection port cover 106 rotates connected to a lower edge of the ejection port 102 via a mounting rod 38 ( Fig. 10 ). The 26. 01. 2025 313892/4 standard dummy bullet 108 typically has a rear end portion (not shown) that is ejected from the ejection port 102 by a front portion (not shown) of the assembly bolt 112.

[031] Figs. 2-10 show an example of a rifle safety device including an ejection port cover 20 and an integrated dummy bullet 26, according to an embodiment thereof. The safety device of the present subject matter replaces the standard dummy bullet 108 and standard ejection port cover; and the dummy bullet 26 is attached to the ejection port cover 20, thereby making the string 1superfluous.

[032] The dummy bullet 26 is connected to the ejection port cover 20 via a mechanical linkage mechanism including a linkage 22 and a connecting rod 24. The connecting rod 24 is held within a protrusion 25 ( Fig. 2 ), near or at, the rear of the dummy bullet 26, at a side facing the ejection port cover 20. The connecting rod 24 rotates within the linkage 22. At the front of the ejection port cover 20 is a front stop 30; and at the rear of the ejection port cover is a rear stop 34.

[033] The linkage 22 slides forward and rearward within a slot 28 thereby allowing the dummy bullet 26 to slide between a forward position ( Fig. 14 ) in the chamber 100 and a retracted position ( Fig. 9 ) into ejection port 102.

[034] The ejection port cover 20 covers the ejection port 102 essentially the same as standard ejection port cover, and rotates open and closed around a shaft 32. Shaft 32 connects ejection port cover 20 to the rifle via an ejection port rod (not shown) of the rifle.

[035] The ejection port cover 20 is structured to rotate around the outward portion of the ejection port 102 and thereby removes the dummy bullet 26 from the ejection port 102 ( Figs. 10 and 11 ).

[036] The dummy bullet 26 is mounted on a linkage 22 connected to the ejection port cover 20 and pulled by a pulling element 36 (e.g. spring, elastic, and the like) outside the chamber 100. The ejection port cover 20 pulls the dummy 313892/4 bullet 26 backward by the pulling element 36. The rifle spring 40 causes the ejection port cover 20 to open, same as is done in the prior art.

[037] The pulling element 36 is stretched when the dummy bullet 26 is in the chamber 100, and therefore pulls the dummy bullet 26 back when the rifle is cocked.

[038] With reference to Fig. 13 and Fig. 14 , in some examples, the ejection port cover 20 has a window 42 so that the position and the existence of the dummy bullet 26 can be verified.

[039] The dummy bullet 26 is inserted into the chamber 100 by pulling the cocking assembly 104 back, and the shooter closes the ejection port cover 20. Returning the cocking assembly 104, pushes the dummy bullet 26 into the chamber 100. Therefore, when the ejection port cover 20 is closed, the dummy bullet 26 is in the chamber 100. When the dummy bullet 26 is in this forward position, the pulling element 36 is stretched . When the cocking assembly 104 is pulled, in order to insert a real bullet to the chamber 100, the pulling element 36 is released, and the dummy bullet moves rearwards by the pulling element to the ejection port, and then out by the ejection port cover.

[040] Fig. 15 shows an example of the rifle safety device where the dummy bullet 26 is moved rearward (out) from the chamber 100 into ejection port 102 by a pushing element 37 (instead of the pulling element 36 – see Fig. 9 ). The pushing element 37 is located forward of the linkage 22. When the dummy bullet 26 is within the chamber 100, the pushing element 37 is in a compressed situation; and when the dummy bullet 26 is in the ejection port 102, the pushing element 37 is in an expanded situation. Another example of the pulling element 36 and the pushing element 37 is a piston.

[041] Advantages of the present invention: (1) The rifle safety device is assembled on the rifle as a single unit. (2) The rifle safety device prevents the entrance of dust. (3) The rifle safety device prevents the dummy bullet from getting stuck in the ejection port as happens occasionally in prior art rifles (4) Using the rifle safety device, the dummy bullet is visible and thus warns of the possibility of 26. 01. 2025 313892/4 a bullet in the chamber. (5) The rifle safety device prevents the dummy bullet from being lost.

[042] It should be understood that the above description is merely exemplary and that there are various embodiments of the present invention that may be devised, mutatis mutandis, and that the features described in the above- described embodiments, and those not described herein, may be used separately or in any suitable combination; and the invention can be devised in accordance with embodiments not necessarily described above.
