Fastening device for weapon accessory
A fastening device is provided for fastening a weapon accessory to a firearm, in particular a hand-held firearm, and to a weapon accessory having a fastening device according to the invention. The weapon accessory is in particular a silencer or a tactical light. The fastening device has a fastening rail, wherein at the rear end of the fastening rail a support surface is formed which rests at least partially on the front end of the trigger of the firearm when the fastening device is fastened to the firearm.
1. A handgun ( 90 ) with a silencer ( 10 ) and with a fixing device for fixing the silencer ( 10 ) to a handle ( 92 ) of the handgun ( 90 ), wherein the fixing device comprises:
a fixation rail ( 30 ) for fixing the fixing device to a mounting rail ( 94 ) of the handgun, wherein the fixation rail ( 30 ) has two upper side walls ( 31 ), the two side walls respectively comprise inner longitudinal guides ( 32 ), which are configured as guide grooves, wherein the guide grooves correspond to the mounting rail ( 94 ),
wherein the mounting rail ( 94 ) is provided at a horizontal section of the handle ( 92 ) directly below a barrel ( 91 ) and forward of a trigger guard ( 97 ) of the handgun ( 90 ),
the fixation rail ( 30 ) is arranged at a rear end wall of a silencer housing ( 11 ) of the silencer ( 10 ), wherein the rear end wall of the silencer housing ( 11 ) is facing the barrel ( 91 ) of the handgun ( 90 ) when fixing the silencer ( 10 ) to the handgun ( 90 ),
wherein the fixation rail ( 30 ) and the silencer ( 10 ) is formed in one piece,
wherein a support surface ( 36 ) is formed at the rear end ( 33 ) of the fixation rail ( 30 ), which at least in sections rests on the front end ( 97 a ) of the trigger guard ( 97 ) of the handgun ( 90 ), if the fixing device is fixed to the handgun,
wherein a surface of the support surface ( 36 ) facing the trigger guard ( 97 ) has a convex curvature,
wherein the front end ( 97 a ) of the trigger guard ( 97 ) is formed as end wall-sided counter support surface, which at least in sections corresponds to the convex support surface ( 36 ),
wherein the support surface ( 36 ) of the fixation rail ( 30 ) rests in a substantially positive-locking manner on the end wall-sided counter support surface ( 97 a ), if the fixing device is fixed to the handgun, such that the silencer ( 10 ) is reliably prevented from oscillating in a vertical direction (P 2 ) after a shot has been fired from the handgun ( 90 ), and
wherein the support surface ( 36 ) at the rear end ( 33 ) of the fixation rail ( 30 ) has an axial recess, with which an axial protrusion or pin ( 97 b ) arranged at the front end ( 97 a ) of the trigger guard ( 97 ) engages in a positive-locking manner, if the fixing device is fixed to the handgun.
2. The handgun of claim 1 , wherein two blades ( 35 ) spaced apart from each other are provided at the rear end ( 33 ) of the fixation rail ( 30 ), which at least in sections protrude in axial direction at the support surface ( 36 ).
3. The handgun of claim 2 , wherein the distance between the two blades ( 35 ) is selected such that it substantially corresponds to the width of the front end of the trigger guard ( 97 ) such that the front end of the trigger guard ( 97 ) at least in sections engages substantially in a positive-locking manner between the two blades ( 35 ), if the fixing device is fixed to the handgun.
4. The handgun of claim 2 , wherein the support surface ( 36 ) extends between the two blades ( 35 ) and perpendicular to the two blades ( 35 ).
5. The handgun of claim 1 , wherein a locking means ( 12 ; 13 ) is provided at the fixation rail ( 30 ), in order to lock the locking device at the gun, wherein the locking means comprises at least one locking rocker ( 13 ), which is arranged pivotably about a pivot axis ( 14 ) at the rear end ( 33 ) of the fixation rail ( 30 ), and which can be brought from a locking position into a release position, wherein the locking rocker ( 13 ) is aligned substantially in parallel to the longitudinal axis (LA) of the fixation rail ( 30 ), and in a state of the fixing device being fixed to the handgun, can be brought into engagement with the trigger guard ( 97 ) of the handgun ( 90 ) in order to lock the fixing device at the handgun.
