DETAILED DESCRIPTION
[0009] The detailed description of exemplary embodiments herein
makes reference to the accompanying drawings, which show exemplary
embodiments by way of illustration and their best mode. While these
exemplary embodiments are described in sufficient detail to enable
those skilled in the art to practice the inventions, it should be
understood that other embodiments may be realized and that logical,
chemical and mechanical changes may be made without departing from
the spirit and scope of the inventions. Thus, the detailed
description herein is presented for purposes of illustration only
and not of limitation. For example, the steps recited in any of the
method or process descriptions may be executed in any order and are
not necessarily limited to the order presented. Furthermore, any
reference to singular includes plural embodiments, and any
reference to more than one component or step may include a singular
embodiment or step. Also, any reference to attached, fixed,
connected or the like may include permanent, removable, temporary,
partial, full and/or any other possible attachment option.
Additionally, any reference to without contact (or similar phrases)
may also include reduced contact or minimal contact.
[0010] In various embodiments, a firearm may comprise a firearm
firing mechanism configured to activate firing of ordnance. Such
firearms can comprise a firing direction F (e.g., a forward
direction) that represents the direction of travel of ordnance
fired from the firearm.
[0011] With reference to FIGS. 1-4, a firearm firing mechanism
("mechanism") 100 (e.g., trigger mechanism, trigger module, trigger
assembly, and/or the like) in accordance with the present
disclosure is illustrated. Mechanism 100 may comprise a firing
mechanism housing 112. In various embodiments, mechanism 100 may
comprise a sear 102 at least partially disposed within said
housing. Sear 102 can comprise, for example, a member configured to
pivot around a point within housing 112.
[0012] In various embodiments, mechanism 100 comprises a sear
activating spring 108. In such embodiments, spring 108 is disposed
at least partially within housing 112, and is configured to rotate
sear 102. For example, a force may be applied to spring 108. When
the tension is released, spring 108 can rotate sear 102.
[0013] Mechanism 100 can further comprise, for example, a
disconnect 104. In various embodiments, disconnect 104 is at least
partially disposed within housing 112, and is configured to engage
with sear 102. For example, sear 102 can be rotated against spring
108 to cause spring 108 to exert a force on sear 102. In such
configurations, disconnect 104 can engage and retain sear 102,
allowing spring 108 to maintain a force against sear 102.
Disconnect 104 can then be released from engagement with sear 102,
allowing spring 108 to rotate sear 102. Moreover, mechanism 100 may
comprise any suitable structure configured to actuate a sear form a
non-firing to a firing position (e.g., fire ordnance) in response
to being actuated.
[0014] In various embodiments, mechanism 100 can further comprise a
trigger component 106 (e.g., trigger shank). Trigger component 106
can, for example, be coupled to disconnect 104. In such
configurations, trigger component 106 can be manually activated,
causing disconnect 104 to be released from engagement with sear 102
and allowing sear 102 to be rotated by spring 108.
[0015] Trigger component 106 can comprise a first profile 110
(e.g., a first portion, a first surface, a first segment, and/or
the like) and a second profile 114 (e.g., a second portion, a
second surface, a second segment, and/or the like). In various
embodiments, first profile 110 and second profile 114 of trigger
component are different from each other. Moreover, the position of
second profile 114 (e.g., the location of second profile 114
relative to the operator, the trigger guard, and/or the rest of the
firearm) may be a function of the shape, geometry and/or angle of
first profile 110. For example, as illustrated in FIGS. 1-4, first
profile 110 can comprise a portion of trigger component 106 which
extends from housing 112. In various embodiments, first profile 110
extends at an angle between about zero and about 180 degrees from a
lower surface 122 of lower receiver 120, in which mechanism 100 is
installed. More specifically, the angle may be between
approximately 60 degrees and 120 degrees. In various embodiments,
first profile 110 can be oriented away from the firearm
operator.
[0016] In various embodiments, second profile 114 (e.g., engagement
portion, finger pad portion, pull portion, and/or the like) may
comprises a curved shape and/or contoured shape. As illustrated in
FIGS. 1-4, second profile 114 can comprise a curved shape that
curves away from the firing direction F. In various embodiments,
second profile 114 can be curved toward a firearm operator.
[0017] In various embodiments, second profile 114 can comprise a
curve that is generally compatible and/or ergonomic to a human
figure. For example, second profile 114 can comprise a curve or
curved section that corresponds to the degree of curvature of an
exemplary human finger. In such embodiments, a firearm operator can
activate trigger component 106 without directly contacting the
portion of trigger component 106 comprising first profile 110.
Instead, activation of trigger component 106 can be achieved solely
through contact with the portion of trigger component 106
comprising second profile 114.
[0018] In various embodiments, second profile 114 may be an
engagement portion. The engagement portion may be formed in and/or
operatively coupled to trigger component 106. The engagement
portion may be configured to receive an input form an operator. The
input may be conducted from second profile 114 (e.g., the
engagement portion) through trigger component 106 to mechanism
100.
[0019] In various embodiments, trigger component 106, and more
specifically, the position and orientation of second profile 114
may provide a uniform, repeatable engagement point for the user. In
contrast, a user may engage a traditional trigger at any point
along the trigger profile created a non-uniform trigger pull for
the user. By making the engagement point (e.g., second profile 114)
uniform in shape and relative location to an operator, the amount
of force associated with a trigger pull may be constant. In this
regard, the operator is able to engage mechanism 100 at a specific
engagement point (e.g., second profile 114). The force associated
with the trigger pull may be adjusted by adjusting the geometry of
trigger component 106 (e.g., by replacing a first trigger component
106 with a first overall profile with a second trigger component
106 having a second overall profile) and/or other components in
mechanism 100 (e.g., springs).
[0020] In various embodiments, a trigger may comprise a front
surface trigger component profile having an upper portion 110, a
transition point 113, a lower portion 114, and an end 115. A first
radius of curvature of upper portion 110 may be different than a
second radius of curvature of the lower portion 114. Transition
point 113 may be the point at which the front surface trigger
component profile transitions from the first radius of curvature to
the second radius of curvature. In various embodiments, the lower
portion 114 may have a length that is defined between transition
point 113 and end 115. This length may be suitable sized for
engagement by a human finger and/or two human fingers. For example,
this length may be for example, approximately 0.5 inch
(approximately 1.2 cm) to approximately 2.5 inches (approximately
6.35 cm).
[0021] Benefits, other advantages, and solutions to problems have
been described herein with regard to specific embodiments.
Furthermore, the connecting lines shown in the various figures
contained herein are intended to represent exemplary functional
relationships and/or physical couplings between the various
elements. It should be noted that many alternative or additional
functional relationships or physical connections may be present in
a practical system. However, the benefits, advantages, solutions to
problems, and any elements that may cause any benefit, advantage,
or solution to occur or become more pronounced are not to be
construed as critical, required, or essential features or elements
of the inventions. The scope of the inventions is accordingly to be
limited by nothing other than the appended claims, in which
reference to an element in the singular is not intended to mean
"one and only one" unless explicitly so stated, but rather "one or
more." Moreover, where a phrase similar to "at least one of A, B,
or C" is used in the claims, it is intended that the phrase be
interpreted to mean that A alone may be present in an embodiment, B
alone may be present in an embodiment, C alone may be present in an
embodiment, or that any combination of the elements A, B and C may
be present in a single embodiment; for example, A and B, A and C, B
and C, or A and B and C. Different cross-hatching is used
throughout the figures to denote different parts but not
necessarily to denote the same or different materials.
[0022] Systems, methods and apparatus are provided herein. In the
detailed description herein, references to "one embodiment", "an
embodiment", "an example embodiment", etc., indicate that the
embodiment described may include a particular feature, structure,
or characteristic, but every embodiment may not necessarily include
the particular feature, structure, or characteristic. Moreover,
such phrases are not necessarily referring to the same embodiment.
Further, when a particular feature, structure, or characteristic is
described in connection with an embodiment, it is submitted that it
is within the knowledge of one skilled in the art to affect such
feature, structure, or characteristic in connection with other
embodiments whether or not explicitly described. After reading the
description, it will be apparent to one skilled in the relevant
art(s) how to implement the disclosure in alternative
embodiments.
[0023] Furthermore, no element, component, or method step in the
present disclosure is intended to be dedicated to the public
regardless of whether the element, component, or method step is
explicitly recited in the claims. No claim element herein is to be
construed under the provisions of 35 U.S.C. 112(f), unless the
element is expressly recited using the phrase "means for." As used
herein, the terms "comprises", "comprising", or any other variation
thereof, are intended to cover a non-exclusive inclusion, such that
a process, method, article, or apparatus that comprises a list of
elements does not include only those elements but may include other
elements not expressly listed or inherent to such process, method,
article, or apparatus.
