PNEUMATIC NAIL GUN WITH SAFETY MECHANISM Russian patent published in 2023 - IPC B25C1/04 

FIELD: pneumatic tools.

SUBSTANCE: invention relates to a pneumatic nail gun. The gun (10) contains a body, a handle, a working cylinder (54) located in the body and a guiding working piston (52) connected to a driving hammer (50) for driving a fastener and configured to be loaded with compressed air when initiating the driving operation, end tool (28) mounted on the body and containing a socket for a fastener driven by a driving hammer (50), a trigger installed on the body and designed to initiate the driving operation, a safety mechanism (34) located in the body and made with the possibility of movement between the locking position and the unlocking position and with the possibility of intervening in the operation of initiating and driving in the locking position so that proper actuation of the trigger device does not lead to the initiation of the driving operation, the control safety chamber (62) located in the housing and configured to bring into or to remove air from it through the throttle (86), and the pressure in the safety chamber (62) of the control applies a control force to the safety mechanism (34), a device for creating a counter force acting on the safety mechanism (34) and directed opposite to the control force, located in the body, while the device for creating a counter force is made in such a way that the value of the counter force is linearly dependent on the operating pressure of the pneumatic nail gun (10), and the counter force is directed to transfer the safety mechanism (34) to the locking position.

EFFECT: preventing the initiation of the driving operation in the locking position.
