US12320605 - Connector for a firearm accessory

The patent describes a connector assembly designed to securely attach a firearm accessory to a muzzle device using a threaded engagement mechanism and clamp members that can be adjusted axially and radially. Additionally, it includes a cam component that facilitates the movement of the clamp members, allowing for easy attachment and detachment of the muzzle device.

Claim 1

1. A connector assembly for connecting a firearm accessory to a muzzle device for a firearm, the connector assembly comprising: a first connector part, and a second connector part engaged to the first connector part by a threaded engagement, the first connector part presenting a first engagement surface, at least two clamp members configured to receive the muzzle device therebetween, the clamp members coupled to the second connector part to be axially and rotationally retained thereto, each of the clamp members presenting a second engagement surface to engage the first engagement surface, and wherein rotation of the first connector part relative to the second connector part in a first direction moves the first connector part from a first relative axial position to a second relative axial position to engage the first engagement surface against the second engagement surfaces to drive the clamp members radially inwards against the muzzle device in an inward radial position to clamp the muzzle device and connect the firearm accessory to the firearm, wherein the connector assembly further comprises a mechanism to drive the clamp members from the inward radial position to an outward radial position when the first connector part is in or moved to the first relative axial position to allow a muzzle device to be received in or removed from the connector assembly, wherein the mechanism comprises a cam component configured to engage an outer surface of the second connector part and to move longitudinally with respect to the first and second connector parts, and wherein the cam component does not rotate relative to the second connector component. a first connector part, and a second connector part engaged to the first connector part by a threaded engagement, the first connector part presenting a first engagement surface, at least two clamp members configured to receive the muzzle device therebetween, the clamp members coupled to the second connector part to be axially and rotationally retained thereto, each of the clamp members presenting a second engagement surface to engage the first engagement surface, and wherein rotation of the first connector part relative to the second connector part in a first direction moves the first connector part from a first relative axial position to a second relative axial position to engage the first engagement surface against the second engagement surfaces to drive the clamp members radially inwards against the muzzle device in an inward radial position to clamp the muzzle device and connect the firearm accessory to the firearm, wherein the connector assembly further comprises a mechanism to drive the clamp members from the inward radial position to an outward radial position when the first connector part is in or moved to the first relative axial position to allow a muzzle device to be received in or removed from the connector assembly, wherein the mechanism comprises a cam component configured to engage an outer surface of the second connector part and to move longitudinally with respect to the first and second connector parts, and wherein the cam component does not rotate relative to the second connector component.
