FIREARMS ACCESSORY DEVICE

TECHNICAL FIELD

The present disclosure relates to firearm accessory devices for mounting on a firearm.

BACKGROUND

Many firearms, particularly rifles, are controlled with the non-firing hand receiving a hand guard surrounding the firearm barrel. Grasping the firearm can be awkward and uncomfortable for users, particularly in extended firing sessions. Standardized mounting rails have made it possible to mount a wide variety of accessories to a firearm. Weapon-mounted firearm accessories have become an important tool for military, police, and civilian firearm users. Presently, many shooters utilize different accessories to enhance their firearm and provide additional functionality which allows for improved firearm utilization. One such accessory is the firearm foregrip. A firearm foregrip is typically attached onto a handguard rail via different mechanisms and vertically oriented or angled. Foregrips usually include an elongated handle that can be gripped by the hand not operating the trigger. Such conventional firearm foregrips may provide additional support and control, they can however become uncomfortable and awkward for users, particularly in extended firing sessions. Any improvements with respect to ergonomic functionality and the ability to employ different support hand holding techniques would be welcome.

In one or more embodiments, the accessory devices disclosed herein are further advantageous in that they include ergonomic features configured to maximize user comfort, accuracy and safety.

SUMMARY

The present disclosure relates to firearm accessory devices for mounting on a firearm, in particular, a hand/finger support/stop having an illumination device for coupling to a handguard, forestock, barrel or accessory rail of a firearm. In one or more embodiments, an accessory device that may be attached to a firearm, the device including a light source and a power source housed within the device. In embodiments, the device may further include one or more activation devices operably and electrically connected to the illumination device and positioned at one or more access openings forwardly oriented in a body portion of the device.

In one or more embodiments, there is disclosed herein an accessory device for a firearm. In embodiments, the device may include a housing removably attachable to the firearm, wherein the housing includes a body portion downwardly extending from a cover portion and including a first trunk portion and forward and rearward portions oppositely extending from an upper portion of the first trunk portion. In embodiments, the forward portion each may have one or more tapered neck portions between the first trunk portion and a forward end portion.

In one or more embodiments, the forward portion includes a second trunk portion extending downwardly forward of the first trunk portion.

Tactile metal domes are placed on printed circuit boards by means of pressure-sensitive adhesive tape or they are captured in a pocket design. In their relaxed state, the tactile metal domes rest on the outer rim of the primary pathway. When pushed, the domes collapse and make contact with the secondary pathway, thereby closing the circuit. Switch contacts of different shapes and actuation forces may be used and may be mounted to a variety of switching surfaces, including single or double-sided printed circuit boards, flex circuits, and membrane switch panels, in accordance to specific applications. The switch contacts can be used for electrical contact, tactile-element only, or both electrical and tactile. Such switch contacts may be obtained from Snaptron located in Windsor, Colorado. The switch contact shown in Appendix A FIGS. is part number F06085 from Snaptron. Examples are described in U.S. patent application Ser. No. 17/465,839, which is herein incorporated by reference in its entirety.
