The present disclosure relates to novel and advantageous firearms. Particularly, the present disclosure relates to a novel and advantageous firing control mechanism for a concealable handgun.
The background description provided herein is for the purpose of generally presenting the context of the disclosure. Work of the presently named inventors, to the extent it is described in this background section, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure.
Some firearms having more than one barrel are configured such that only one barrel will fire at a time. For example, a double barreled derringer is configured to fire alternatively out of the two barrels. Various mechanisms may be used to alternately select which barrel will be used to fire each shot. Some multiple-barrel firearms have a hammer configured to alternately select between each of two firing pins associated with the two barrels. Where a multiple-barrel firearm is configured to be concealable and/or relatively small or compact, it may be difficult to employ conventional multiple-barrel firing mechanisms due to space constraints and/or concealability considerations. Thus, there is a need in the art for a multiple-barrel firing control mechanism that may be suitable for a relatively compact and/or concealable firearm.
The following presents a simplified summary of one or more embodiments of the present disclosure in order to provide a basic understanding of such embodiments. This summary is not an extensive overview of all contemplated embodiments, and is intended to neither identify key or critical elements of all embodiments, nor delineate the scope of any or all embodiments.

The trigger assembly 204 may be configured to cause retraction or compression of the firing pin springs so as to cause each of the firing pins, alternately, to strike a bullet when the trigger assembly is actuated by a user. The trigger assembly 204 is shown, in an exploded view, in
Each pawl 216 may have a mounting portion 234, an arm portion 236, and a sear engaging portion 238. The mounting portion 234 may be configured to mount the pawl 216 to the mounting arrangement 231. For example, the mounting portion 234 may have an opening configured to receive a mounting peg. The arm portion 236 may extend between the mounting portion and the sear engaging portion 238. The sear engaging portion 238 may extend laterally from an end of the arm portion and may be configured to latch or hook onto a sear lug 226 so as to engage a firing pin and cause the firing pin to fire. In some embodiments, a torsion spring may be configured to bias each pawl 216 toward a particular direction. For example, a first torsion spring may operate to bias a first pawl 216 upward toward an upper firing pin 212a, and a second torsion spring may operate to bias a second pawl downward toward a lower firing pin 212b.
The cog pusher 232 may have a mounting portion 240 and a cog engaging portion 242. The mounting portion 240 may be configured to mount the cog pusher 232 to the mounting arrangement 231. For example, the mounting portion 240 may have an opening configured to receive a mounting peg. The cog engaging portion 242 may extend from the mounting portion and may be configured to catch or latch onto the cog 214 so as to cause the cog to rotate about an axis. In some embodiments, the cog engaging portion 242 may have a generally curved or arced shape and may have a length suitable for engaging with the cog 214 as the trigger assembly 204 is pulled back by a user. The length and shape of the cog engaging portion 242 may be configured to rotate the cog 214 to a particularly desired degree of rotation when the trigger assembly 204 is depressed toward the rear wall 262 of the housing 202. For example, the length and shape of the cog engaging portion 242 may be configured to rotate the cog 214 between approximately 45 degrees and approximately 180 degrees, or between approximately 60 degrees 120 degrees, or between approximately 80 degrees and approximately 100 degrees. In some embodiments, the length and shape of the cog engaging portion 242 may be configured to rotate the cog 214 approximately 90 degrees on each trigger pull. In other embodiments, the length and shape of the cog engaging portion 242 may be configured to rotate the cog approximately 45 degrees, approximately 180 degrees, approximately 360 degrees, or to any other suitable degree of rotation. In some embodiments, a spring may allow the cog pusher 232 to hinge or pivot with respect to the mounting arrangement 231.

In some embodiments, each sidewall 252 may have a pawl channel 256, which may be or include a cutout or groove in the sidewall. The pawl channel 256 may be configured to engage with a sear engaging portion 238 of a pawl 216. In particular the channels 256 may each be configured such that the sear engaging portion 238 of a pawl 216 may extend laterally across the channel. The channels 256 may be configured to position the pawls 216 generally toward one firing pin 212 at a time, so as to prevent the pawls from each engaging a firing pin at the same time.
Additionally, each sidewall 252 may have a tab 246 extending therefrom. Each tab 246 may extend laterally inward toward an opposing sidewall 252. The two tabs 246 may be configured to encourage selection of only one firing pin 212 at a time by the pawls 216. In particular, each tab 246 may be arranged on the sidewall so as to align with a sear lug 226 of a firing pin 212. An upper tab 246a (nearest the upper wall 250) may be configured to align with a sear lug 226 of the upper firing pin 212a when the selector 218 is in a high position. Similarly, a lower tab 246b (nearest the lower wall 254) may align with a sear lug 226 of the lower firing pin 212b when the selector 218 is in a low position. Each tab 246 may operate to engage with its corresponding sear lug 226 so as to prevent engagement of the sear lug by a pawl 216.
The pawl selector 218 may be arranged such that it may contact the cog 214 as the cog rotates between high and low positions. In particular, the pawl selector 218 may be configured such that the lower wall 254 may contact the cog 214. Fins 244 of the cog 214 may operatively push the selector 218 into a high position, and allow the selector to drop back down to a low position as the cog 214 rotates.
In use, a firearm of the present disclosure may operate to fire one round through one barrel upon each pull of the trigger. A firing control assembly of the present disclosure may operate to select a single firing pin upon a trigger pull to ensure that only one firing pin is actuated at a time. Where the firearm has two firing pins, the firing control assembly may alternately select between the two firing pins, alternating back and forth between the two pins, while selecting only one pin on each trigger pull.
In particular, while holding the firearm 200 by its handle, a user may depress, or pull back on, the trigger 230 a first time to fire a first round, causing the trigger assembly 204 (including the pawls 216 and cog pusher 232) to move toward the user or toward the rear wall 262 of the firearm. As the trigger assembly 204 moves toward the rear wall 262, the cog pusher 232 may engage with the cog 214 by pushing against a fin 244 of the cog, thereby causing the cog to rotate about its axis. As described above, each trigger 230 pull may cause the cog 214 to rotate approximately 90 degrees. However, in other embodiments, the cog pusher 232 may be configured to cause any other suitable degree of rotation of the cog 214. Additionally, as the trigger assembly 204 moves toward the rear wall 262, the two pawls 216 may each move toward the sear lugs 226. Simultaneously, as the cog 214 rotates, a fin 244 may engage with the pawl selector 218, thus pushing the pawl selector upward, toward the upper wall of the firearm, away from the cog, and into a high position.
As the trigger assembly 204 continues to depress back toward the rear wall 262 of the housing 202, a pawl 216 may engage with the sear lug 226 of the upper firing pin 212a, pushing the firing pin back to compress the primary spring 222 of that firing pin, and causing the firing pin to strike toward a round. This may in turn cause a round to fire through the upper barrel 208a. As the round fires, the pawl 216 may ride down the ramp 221 of the upper spacer 220a associated with the engaged upper firing pin 212a, thus guiding the pawl off of the sear lug 226 to disengage the pawl from the sear lug and firing pin. After the upper firing pin 212a fires the round, and the user releases the trigger 230, the trigger assembly 204 may move forward toward a front wall 260 of the housing 202.
A user may depress the trigger 230 a second time to fire a second round. As the trigger assembly 204 moves toward the rear wall 262 once again, the cog pusher 232 may cause the cog 214 to rotate approximately 90 degrees or another suitable degree. Rotation of the cog 214 may cause a fin 244 to move out of alignment with the pawl selector 218, and may thus bring the pawl selector into a low position. As the pawl selector 218 moves into a low position, it may pull or guide both pawls 216, via the pawl channels 256 generally downward toward the lower firing pin 212b, and may thus prevent either pawl from engaging with the upper firing pin 212a. Additionally, with the selector 218 in the low position, the upper tab 246a may align with the sear lug 226 of the upper firing pin 212a and may operate to hold the firing pin in place and prevent it from being engaged by a pawl. Thus, by virtue of being in a low position, the pawl selector 218 may prevent the upper sear lug 226 and firing pin 212a from being engaged by a pawl 216, but may permit the lower sear lug 226 and firing pin 212b to be engaged by a pawl.
As the trigger assembly 204 continues to depress back toward the rear wall of the firearm 200, a pawl 216 may engage with the sear lug 226 and lower firing pin 212b, pushing the firing pin back to compress the primary spring 222 of that firing pin, and causing the firing pin to strike toward a round. This may in turn cause a round to fire through the lower barrel 208b. As the round fires, the pawl 216 may ride up the ramp 221 of the lower spacer 220b associated with the engaged lower firing pin 212b, thus guiding the pawl off of the sear lug 226 to disengage the pawl from the sear lug and firing pin. After the lower firing pin 212b fires the round, and the user releases the trigger 230, the trigger assembly 204 may move forward toward the front wall 260 of the housing 202.
It may thus be appreciated that position of the pawl selector 218 may determine which of the two firing pins 212 is engaged by a pawl. It may further be appreciated that rotation of the cog fins 244 may cause the pawl selector to alternate between a high position and a low position with each depression of the trigger 230. In some embodiments, a firing control assembly of the present disclosure may have a single pawl that operates to alternately engage both firing pins. For example, the pawl selector may operate to guide the pawl toward an upper firing pin when in a high position and may operate to guide the pawl toward a lower firing pin when in a low position.
It is further to be appreciated that while the firing control mechanism is described above with respect to forward and rearward movements of the trigger assembly 204 and upper and lower (up and down) movements of the pawl selector 218, the components may move in any suitable direction depending on the orientation or configuration of the firing control mechanism. In particular, where a firearm of the present disclosure has a side-by-side barrel and firing pin configuration, the pawl selector may be configured to move side to side to cause alternating selection of one of the two firing pins. Still other configurations and orientations are envisioned.
As used herein, the terms “substantially” or “generally” refer to the complete or nearly complete extent or degree of an action, characteristic, property, state, structure, item, or result. For example, an object that is “substantially” or “generally” enclosed would mean that the object is either completely enclosed or nearly completely enclosed. The exact allowable degree of deviation from absolute completeness may in some cases depend on the specific context. However, generally speaking, the nearness of completion will be so as to have generally the same overall result as if absolute and total completion were obtained. The use of “substantially” or “generally” is equally applicable when used in a negative connotation to refer to the complete or near complete lack of an action, characteristic, property, state, structure, item, or result. For example, an element, combination, embodiment, or composition that is “substantially free of” or “generally free of” an element may still actually contain such element as long as there is generally no significant effect thereof.
To aid the Patent Office and any readers of any patent issued on this application in interpreting the claims appended hereto, applicants wish to note that they do not intend any of the appended claims or claim elements to invoke 35 U.S.C. § 112(f) unless the words “means for” or “step for” are explicitly used in the particular claim.
Additionally, as used herein, the phrase “at least one of [X] and [Y],” where X and Y are different components that may be included in an embodiment of the present disclosure, means that the embodiment could include component X without component Y, the embodiment could include the component Y without component X, or the embodiment could include both components X and Y. Similarly, when used with respect to three or more components, such as “at least one of [X], [Y], and [Z],” the phrase means that the embodiment could include any one of the three or more components, any combination or sub-combination of any of the components, or all of the components.
