[0022] Other aspects and advantages of the present invention will become apparent upon consideration of the following detailed description, wherein similar structures have similar reference numerals.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] The foregoing and other features and advantages of the invention will become more apparent from the following detailed description of exemplary embodiments, read in conjunction with the accompanying drawings. The detailed description and drawings are merely illustrative of the invention rather than limiting, the scope of the invention being defined by the appended claims and equivalents thereof.

[0024] FIG. 1 and FIG. 2 represent a safety trigger system 100. The trigger system comprises 100 a trigger housing 102, a safety blade member 104, a safety latch member 106, a resistance member 108 (not shown in FIG. 1 and FIG. 2), and a plurality of pivot members 110, 112.

[0025] The trigger housing 102 is further detailed in FIG. 3 and the partial cross section shown in FIG. 4. As shown in FIG. 3. the trigger housing 102 comprises a slot 114 configured to accommodate the assembly of safety blade member 104 and the safety latch member 106.

[0026] As shown in the cross section of the trigger system 100 in FIG. 4, the safety blade member 104 is disposed in the trigger housing slot 114 and rotatably coupled to the trigger housing 102 through a first pivot member 110. In an assembled first state, the safety blade depression portion 111 protrudes through the front of the trigger housing allowing access for digital depression. The safety latch member 106 is disposed in a rear portion of the trigger housing slot 114 and rotatably coupled to the trigger housing 102 through a second pivot member 110. In an assembled state, a safety latch engagement portion 107 is physically engaged with a safety blade engagement portion 105 and a safety latch interference portion 109 protrudes from a top portion of the trigger housing 102.

[0027] Further As shown in FIG. 4, the resistance member 108 is coupled to the safety latch member resistance member locating feature 116 and a trigger housing resistance member locating feature 118. The resistance member is configured to apply a resistive force between the trigger housing 102 and the safety latch member 106 rotatably biasing the safety latch member along the second pivot member 112 into the first assembled pre-depressed position in contact with the safety blade member 104. The safety latch member resistance member locating feature 116 may comprise a stud inserted into the resistance member 108 configured to restrict movement of the resistance member or a bore, hole, or pocket in which the resistance member 108 is inserted into. Further, the trigger housing resistance member locating feature 118 may comprise a stud inserted into the resistance member configured to restrict movement of the resistance member or a bore, hole, or pocket in which the resistance member is inserted into. One example of a resistive member 108 includes but is not limited to a spring.

[0028] In an alternative aspect, as shown in FIG. 5 and FIG. 6, the resistance member is coupled to the first pivot member and the second pivot member and configured to apply a resistive force to both the safety blade member 104 and safety latch member 106 rotatably biasing both the safety blade member 104 and safety latch member 106 along the pivot members 110 and 112 into the assembled, pre-depressed positions. Upon depression of the safety blade, the resistive force of the resistive member is overcome. In a depressed state, the safety blade is rotated into the trigger housing, which in turn applies a force onto the bottom portion of the safety latch causing the safety latch to overcome the resistive force of the resistance member and rotate about the second pivot member. One example of a resistive member includes but is not limited to a torsion spring.

[0029] In either resistance member 108 configuration one of skill in the art would recognize that a number of different types spring members may be used to bias the safety blade member 104 or safety latch member 106 into appropriate positions and that the resistance member 108 may be assembled directly to the safety blade member 104 or safety latch member 106 or other components within the trigger housing 102.

[0030] In operation as shown in FIGS. 7-8, the trigger system 100 is assembled into a firearm 200. In the assembled state, the upper portion of the safety latch member 106 interferes with the firearm housing 202 and prevents travel of the trigger system 100 without depression of the safety blade member 104. In a pre-depressed state, the trigger system 100 is prevented from traveling the entire trigger stroke required to release the firing pin of the firearm 200. In a depressed state, the depression of the safety blade member 104 applies a force to the bottom portion of the safety latch member 106 causing the rotation of the safety latch member 106 about the second pivot member 112. The safety latch member 106 in a depressed rotated position no longer interferes with the firearm housing 202 and allows for the trigger system 100 to travel the entire trigger stroke and release the firing pin of the firearm 200.

[0031] The interaction between the safety blade member 104 and the safety latch member 106 allows for a multiplication of the travel distances between each part respectively. Ultimately, this interaction allows for the safety blade member 104 to remain within a comfortable travel range, while the safety latch member 106 travels at a greater or smaller distance (depending on the firearm design) to achieve locking and unlocking of the trigger assembly 100.

[0032] In another aspect, a method of securing a firearm comprises the steps of installing a safety trigger assembly 100 in a firearm housing 200 the safety trigger system 100 comprising a trigger housing 102, a safety blade member 104, a safety latch member 106, a resistance member 108, and a plurality of pivot members 110, 112 wherein in a first pre-depressed state, the safety latch member 106 interferes with the firearm housing 200 preventing a complete trigger travel stroke and preventing the release of the firearm firing pin.

[0033] In yet another aspect, a method firing a firearm comprising a safety trigger assembly comprises the steps of depressing the trigger housing 102 and safety blade member 104, rotating the safety blade member 104 into the safety latch member 106, rotating the safety latch member 106 to clear an interference with the firearm housing 200, allowing the full trigger stroke to release the firearm firing pin.

[0034] Those of ordinary skill in the art will understand and appreciate the aforementioned description of the invention has been made with reference to certain exemplary embodiments of the invention, which describe a safety trigger system and method of use. Those of skill in the art will understand that obvious variations in construction, material, dimensions or properties may be made without departing from the scope of the invention which is intended to be limited only by the claims appended hereto.
