Mounting device for a telescopic sight on a hunting or sports weapon with at least one resilient stay bolt

A mounting device for the detachable mounting of a telescopic sight on a weapon, comprising:

• a base rail attachable to the weapon, and
• a mounting rail attachable to the telescoping sight,
• the mounting rail being connectable to the base rail by at least one locking element,
• wherein the locking element comprises a clamping shaft held rotatably in a first one of the base rail and the mounting rail,
• wherein a second one of the base rail and the mounting rail comprises a stay bolt,
• the clamping shaft having at least one wedge recess which, during rotating actuation of the locking element, can be brought into force-fitted engagement with a recess of the stay bolt,
• wherein the stay bolt is firmly attached on the second one of the rails and can be clamped or locked with the clamping shaft mounted in a spring-loaded manner on the first one of the rails,
• the locking element being configured such that the rotating actuation of the locking element causes displacement of the stay bolt in the axial direction of the stay bolt, thereby generating at least one clamping force acting between the base rail and the mounting rail perpendicularly to the axial direction (longitudinal direction) of the base rail and the mounting rail, resulting in an interlocking and force-fitted connection between the base rail and the mounting rail,
• wherein the locking element, during clamping or locking between the base rail and the mounting rail, mounted interlocked thereon, additionally generates a displacement force acting in the axial direction (longitudinal direction) of the base rail and the mounting rail.
