Receiver for securing a firearm

Abstract

A barrel of a firearm is held by a firearm restraint housing having a pair of spaced apart rotors rotatably mounted and contoured for receiving the barrel of the firearm therebetween. A slide member is positionable in interference with rotation of the rotors in its first position and in non-interference with rotation of the rotors in its second position. The position of the slide is determined electromechanically or by a hand key operated lock. The rotors are contoured so that withdrawal of the firearm barrel counter-rotates them into a barrel receiving attitude, and further, placement of the barrel between the rotors forces them into counter-rotation for locking around the barrel.

1 . An apparatus for securing a barrel of a firearm, the apparatus comprising: a housing, and supported by the housing, a pair of spaced apart rotors rotatably mounted and contoured for receiving the barrel of the firearm therebetween; and a positionable member in interference with rotation of the rotors in a first position and in non-interference with rotation of the rotors in a second position; the rotors further contoured so that withdrawal of the firearm barrel from between the rotors counter-rotates the rotors into a barrel receiving attitude, and further, so that placement of the barrel between the rotors, with the rotors in the barrel receiving attitude, counter-rotates the rotors into a barrel locking attitude.  
   
   
       2 . The apparatus of  claim 1  wherein the housing comprises two housing portions joined at medial abutment surfaces.  
   
   
       3 . The apparatus of  claim 1  wherein the housing provides a housing notch; contoured elements of the rotors extending from opposing sides of the housing notch.  
   
   
       4 . The apparatus of  claim 3  wherein the contoured elements of the rotors comprise concave surfaces thereon.  
   
   
       5 . The apparatus of  claim 4  wherein the concave surfaces on each of the rotors comprise two opposing concave surfaces.  
   
   
       6 . The apparatus of  claim 5  wherein the rotors each provide two first rotor grooves each of the first rotor grooves positionally associated with one of the concave surfaces.  
   
   
       7 . The apparatus of  claim 1  wherein a slide provides a pair of slide grooves, the rotors each providing a first rotor groove, and the housing providing a pair of pin grooves; such that with the slide positioned in a first slide position, the slide grooves are misaligned with the pin grooves, and with the slide positioned in a second slide position, the slide grooves are aligned with the pin grooves.  
   
   
       8 . The apparatus of  claim 7  further comprising a pair of locking pins engaged with the pin grooves of the housing; the locking pins engaging the first rotor grooves for locking the rotors in the barrel locking attitude when the slide grooves are misaligned with the locking pins; the pin grooves located and sized as to release the locking pins from the first rotor grooves when the slide grooves are aligned with the locking pins.  
   
   
       9 . The apparatus of  claim 7  wherein the rotors each provide a second rotor groove, the second rotor grooves aligned with the locking pins when the rotors are in the barrel receiving attitude for securing the rotors in an unlocked orientation.  
   
   
       10 . The apparatus of  claim 1  further comprising a motive device engaged with the slide for placing the slide grooves between the aligned and the misaligned positions with the locking pins.
