DEVICE FOR JOINING STRUCTURAL MEMBERS Russian patent published in 2006 - IPC F16B2/06 B60P1/28 B60D1/00 

FIELD: friction-grip releasable fastenings.

SUBSTANCE: device comprises housing (1) with cylindrical passages (9) that receive rods (8). The housing receives pin (2) with conical tip. Each of the rods is provided with locator (4), which is in a contact with the pin, rod guide (7), piston (3) with inner and outer collars, and baffle (6), is secured in the cylindrical passage of the housing. The spaces between the baffles and pistons are in communication with the actuator through oil ducts, cock, and hydraulic pump. The spaces downstream of the pistons are in communication with the atmosphere through the valves. The diameter of the tip is larger than that of the pin that enters the conical groove in the housing. The pickup of position of the pin is located at the top of the housing. The cylindrical passages receive the pickups of the stroke of the locators. The pickups are connected with the power source and signaling lamps of the pickups of the pin position and pickups of the piston stroke.

EFFECT: expanded functional capabilities.
