US12392573 - Hand-held gun

A hand-held gun having a grip part and a breech part movably supported in a longitudinal direction thereon is disclosed. A breech spring arrangement urges breech part in its initial position relative to grip part. For this purpose, breech spring arrangement is supported between the breech part and grip part. Starting from the initial position, breech part can move against the closing force of breech spring arrangement into an abutment position in which it abuts against a buffer body. Starting from the abutment position, breech part can be moved under elastic compression of buffer body in the longitudinal direction into a retracted position. In the movement area between the abutment position and the retracted position, a compression force is applied by the compressed buffer body in addition to the closing force of the breech spring arrangement between the grip part and the breech part.

The patent describes a hand-held gun featuring a grip part and a breech part that moves longitudinally, supported by a breech spring arrangement that maintains the breech part in an initial position. Additionally, an elastically deformable buffer body is included, which compresses when the breech part is retracted, enhancing the firearm’s operation.

Claim 1

A hand-held gun ( 20 ) comprising: a grip part ( 21 ); a breech part ( 37 ) movably supported on the grip part ( 21 ) in a longitudinal direction (L) between an initial position (I) and a retracted position (III); a breech spring arrangement ( 25 ) configured to urge the breech part ( 37 ) in the initial position (I); and an elastically deformable buffer body ( 24 ) arranged on the grip part ( 21 ), wherein a longitudinal distance is present in the longitudinal direction (L) between the buffer body ( 24 ) and the breech part ( 37 ) in the initial position (I) of the breech part ( 37 ), and wherein the breech part ( 37 ) elastically compresses the buffer body ( 24 ) in the retracted position (III) of the breech part ( 37 ); wherein the buffer body ( 24 ) is u-shaped and defines a longitudinal opening ( 62 ) through which the breech spring arrangement ( 25 ) extends at least partly, wherein the longitudinal opening ( 62 ) is open in a vertical direction orthogonal to the longitudinal direction. a grip part ( 21 ); a breech part ( 37 ) movably supported on the grip part ( 21 ) in a longitudinal direction (L) between an initial position (I) and a retracted position (III); a breech spring arrangement ( 25 ) configured to urge the breech part ( 37 ) in the initial position (I); and an elastically deformable buffer body ( 24 ) arranged on the grip part ( 21 ), wherein a longitudinal distance is present in the longitudinal direction (L) between the buffer body ( 24 ) and the breech part ( 37 ) in the initial position (I) of the breech part ( 37 ), and wherein the breech part ( 37 ) elastically compresses the buffer body ( 24 ) in the retracted position (III) of the breech part ( 37 ); wherein the buffer body ( 24 ) is u-shaped and defines a longitudinal opening ( 62 ) through which the breech spring arrangement ( 25 ) extends at least partly, wherein the longitudinal opening ( 62 ) is open in a vertical direction orthogonal to the longitudinal direction.
