## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
The disclosure claims priority to, the benefit of, and is a continuation application of U.S. application Ser. No. 16/423,790, filed May 28, 2019, which claims priority to and the benefit of U.S. Provisional Application No. 62/678,145, filed May 30, 2018, which are all incorporated by reference herein in their entireties.


TECHNICAL FIELD
The present application relates generally to firearm trigger safety mechanisms.
BACKGROUND
Firearm safety mechanisms have been an integral and important part of modern firearms. Firearm safety mechanisms prevent the unintentional discharge of a firearm. Typical firearm safety mechanisms include a manual safety, grip safety, drop safety, or some other apparatus configured to prevent a firearm from discharging a projectile. A trigger safety is one example of a firearm safety mechanism. Generally, the trigger safety uses a lever component to prevent the firing pin and the trigger bar from moving in coordination with a trigger pull unless the lever component is also pulled. Traditional trigger safety mechanisms use the firearm's exterior body to prevent accidental discharge. However, using the exterior body to prevent accidental discharges can be unsightly and potentially dangerous if the exterior body is damaged.

DETAILED DESCRIPTION
The present disclosure provides for a firearm safety mechanism assembly, which includes a firearm and a trigger safety mechanism. The trigger safety mechanism is disposed within the firearm and adapted to prevent rotation of a trigger without actuation of a lever nested within the trigger. For example, the firearm internals (e.g., receiver) can include a housing pin rigidly placed within the firearm. The lever nested within the trigger can rotate between a first position and a second position. In the first position, the lever abuts the housing pin thereby preventing rotation of the trigger. As the lever actuates to a second position, the trigger can rotate to discharge a firearm. One benefit of the trigger safety mechanism is to provide an extra layer of safety to the firearm but still allow for quick discharge of the firearm.
The disclosure now will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments are shown. The concepts discussed herein may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these examples are provided so that this disclosure will be thorough and complete, and will fully convey the scope to those of ordinary skill in the art. Like numbers refer to like, but not necessarily the same or identical, elements throughout.
FIG. 1 is a side view of a trigger safety mechanism in a disengaged position according to one or more embodiments of the disclosure. FIG. 2 is a rear view of the trigger safety mechanism according to one or more embodiments of the disclosure. FIG. 3 is a top rear perspective view of the trigger safety mechanism according to one or more embodiments of the disclosure. Referring to FIGS. 1-3, the trigger safety mechanism 102 includes a plate 104 extending from a plate first end 106 to a plate second end 108. The plate 104 can be pill-shaped, placed within a firearm 154 (e.g., as shown in FIG. 4), and configured to rotate clockwise and counterclockwise. The plate 104 may be any geometric shape (e.g., circular, rectangular, triangular). The plate 104 can attach to a trigger bar within a firearm. That is, the plate 104 can actuate to discharge the firearm 154. Approximate to the plate second end 108 is a rod 110 extending therefrom. For example, the rod 110 can include a fore end 111A and an aft end 111B. The aft end 111B of the rod is coupled to the plate 104. The fore end 111A can include a boss 113 configured to rest within a complementary aperture (not shown) within the firearm receiver 156 (e.g., as shown in FIG. 4) about which the rod 110 rotates. The fore end 111A of the rod 110 can be disposed on a first face 107 of the plate 104. The rod 110 may be disposed through the plate or on the second face 109 of the plate 104.
Referring to FIGS. 1-3, the trigger safety mechanism 102 includes a trigger 112 coupled to the rod 110. In one example, the trigger 112 includes a trigger top end 114 and a trigger bottom end 116. The trigger top end 114 is coupled to the rod 110 along a least a portion of its length. The trigger bottom end 116 can be freely disposed within the trigger guard 158 (e.g., as shown in FIG. 4). Between the trigger top end 114 and the trigger bottom end 116 can be a set of trigger arms (e.g., a trigger first arm 118 and a trigger second arm 120). For example, the trigger first arm 118 can be disposed adjacent to the fore end 111A of the rod 110, and the trigger second arm 120 can be disposed adjacent to the aft end 111B of the rod 110. Each trigger arm can be substantially flat along one surface of the trigger and angled along the other surface. In other examples, the trigger arms can be arcuate or some other shape. In one example, a wedge 138 can extend from one side of the trigger 112, adjacent to the trigger top end 114. The wedge 138 can be a substantially rectangular shape configured to abut the firearm 154 to prevent rotation. That is, the wedge 138 can rest against a firearm surface within the trigger guard 158 when the trigger 112 is in the released position 144.
The trigger safety mechanism 102 can include a lever 122 nested within the trigger 112. In some examples, the lever 122 is anchored within the trigger 112 about a joint 128. That is, the lever 122 can rotate about the joint 128. Referring to FIGS. 1-3, the joint 128 is disposed between the trigger top end 114 and the trigger bottom end 116 as well as between the trigger first arm 118 and the trigger second arm 120. The joint 128 can be a pin joint. In other examples, the joint 128 may be a ball joint, pivot joint, or hinge joint. The lever 122 can include a lever first end 124A and a lever second end 124B. The joint 128 is located between the lever first end 124A and the lever second end 124B.
Adjacent to the joint 128, a channel 130 extends between the trigger 112 and the lever 122. In one example, a channel first portion 132 is disposed within the trigger 112 and a channel second portion 134 is disposed in the lever 122. The channel first portion 132 and the channel second portion 134 can align when the trigger 112 and the lever 122 are secured about the joint 128. A biasing member 136 can be disposed within the channel 130. In this manner, the biasing member 136 can be a compression spring configured to actuate the lever 122 and the trigger 112 in opposing rotational directions. That is, the biasing member 136 can actuate between a resting position 146 and a compressed position 148. In some examples, when the lever second end 124B is rotated in a counterclockwise direction toward the trigger bottom end 116, the biasing member 136 is placed into a compressed position. When the lever 122 is released, the biasing member 136 can extend to the resting position thereby pushing the lever 122 in the clockwise direction. The trigger 112, the lever 122, and the biasing member 136 may rotate clockwise or counterclockwise directions. The biasing member 136 may be a compression spring, tension spring, extension spring, torsion spring, or some other type of spring. When a force does not act on the lever 122, the lever 122 may be biased to rotate in a clockwise motion back to a first position 150 via the biasing member 136.
Referring to FIGS. 4-6, the firearm safety mechanism assembly 100 is shown actuating between a safety position (e.g., as shown in FIG. 4) and a discharging position (e.g., as shown in FIG. 6). As shown in FIG. 4, the lever 122 is in the first position 150. In the first position 150, the lever 122 rests actuated where the lever first end 124A abuts a housing pin 140 and the lever second end 124B is not aligned with the trigger bottom end 116. In some examples, the housing pin 140 can be a cylindrical boss disposed within the firearm 154. In other examples, the housing pin 140 may be a hook, c-shaped, rectangular, square, or some other shape. The lever 122 may have a complementary shape to the housing pin 140 to engage the housing pin 140 when the lever 122 is not rotated within the trigger 112. In this manner, the lever second end 124B abutting the housing pin 140 prevents rotation of the trigger 112 from the released position 144 to a trigger pull position 142. FIG. 4 depicts the trigger 112 in the released position 144. In the first position 150, the biasing member 136 is in the resting position 146. The wedge 138 abuts the firearm 154 in the released position 144.
FIG. 5 depicts the lever 122 in the second position 152. In some examples, a user applies a force to the lever first surface 126 thereby rotating the lever about the joint 128. The lever first surface 126 can sit flush with the trigger 112 surface and the lever 122 can be substantially disposed between the trigger first arm 118 and the trigger second arm 120. In other examples, the lever 122 can provide textile feedback and not sit flush within the trigger 112. In the second position 152, the lever second end 124B rotates between the trigger first arm 118 and the trigger second arm 120. The lever first end 124A rotates away from the housing pin 140. As the lever 122 rotates to the second position 152 the biasing member 136 actuates to the compressed position 148 within the channel 130.
FIG. 6 depicts the lever 122 in the second position, the biasing member 136 in the compressed position 148, and the trigger 112 in the trigger pull position 142. In this manner, the trigger 112 is configured to discharge the firearm 154. In some examples, the trigger top end 114 rotates to abut the housing pin 140. In other examples, the trigger top end 114 does not contact the housing pin 140 upon rotation. The trigger 112 is capable of rotation by the lever first end 124A not abutting the housing pin 140. The wedge 138 rotates in the same direction as the trigger 112. One benefit of rotating the lever 122 simultaneously with the trigger 112 is to allow for ease of use as well as promote safety.
