Patent CZ-278066-B6 (CZ)
Title: Hand-held nailing gun
Inventor: GASSNER THEO
IPC: B25C1/18
Filed: 1987-02-20
Abstract: An explosive powder charge operated fastening member driving tool has a muzzle part which can be locked within and released and removed from the tool housing by rotational movement and axial movement relative to the housing. When the tool is not ready to be fired, a contact pressure sensor projects from the front end of the muzzle part. By pressing the sensor opposite to the firing direction it compresses a firing mechanism spring and the tool is ready to be fired. Stop elements are provided on the muzzle part and stop surfaces are located on the tool housing. When the muzzle part is in the unlocked condition, the stop elements can abut the stop surfaces and block the displacement of the contact pressure sensor preventing it from compressing the firing spring mechanism so that the driving tool cannot be placed in the ready-to-fire condition.
