FI3650619T3 - Locking system and method for opening and closing an element - Google Patents

Claims (12)

PATENT CLAIMS 1. A locking system (1) for an element (2) that can be opened and closed, which system comprises a safety lock (8) on the edge of the element (2) and a locking element (9) on its opposite edge, and the safety lock (8) of the tension-transmitting element (10) and between the locking member (9), which safety lock (8) comprises the body (17); for unlocking the safety lock (8) and the locking member (9) of the turning member (11); of the locking part (12), which is arranged to move between the open and locked positions, whereby the locking part (12) is arranged to prevent the movement of the turning member (11) when the locking part (12) is in the locked position and to allow the turning member (11) to move the locking part (12) in the open position and pressed into the body (17); and which locking system (1) is arranged in the open position of the locking part (12) to allow the movement of the turning member (11), whereby the member (10) transmitting the tensile stress moves at least partially inside the safety lock (8), thereby opening the safety lock (8) and the locking member (9) ) of the lock. 2. The locking system (1) according to claim 1, where the safety lock (8) and the locking member (9) are arranged to be opened by pressing the locking part (12) inside the body (17) and simultaneously moving the turning member (11). 3. The locking system (1) according to claim 1 or 2, where the safety lock (8) further comprises a body (17) and an axle (13) functionally connected to it, and the locking element (9) comprises a pin, which the locking system (1) is arranged in the open position of the locking part (12) to allow the movement of the turning member (11), in which case the member (10) transmitting tensile stress is one-piece extending through the body (17) of the safety lock (8) from the pin of the locking member (9) to the frame (13) and arranged to pull the locking member (9) pin and safety lock (8) tent (13) to the open position. 4. The locking system (1) according to claim 3, in which the body (14) of the turning member (11) contains turning pins (21) which are placed at the end of the distance from the central axis of the body (14), so that when the turning member (11) is turned, the pivot pins (21) deviate the member (10) transmitting the tensile stress, causing it to move partially inside the safety lock (8). 5. The locking system (1) according to claim 3 or 4, which further comprises a pin (18) of the axle (13), which is arranged in the locked position of the locking part (12) to hit the stop (23) of the body of the turning member and thus prevent the axle (13) from opening. 6. The locking system (1) according to claim 1, where the safety lock (8) comprises a body (17); an axle (13) operatively connected to the frame (17); to unlock the axle (13) of the safety lock (8) of the pivoting member (11) attached to the frame (17); the locking part (12) attached to the frame (14) of the pivoting member (11), arranged to move between the open and locked positions, which locking part (12) is arranged to prevent the movement of the pivoting member (11) when the locking part (12) is in the locked position and to allow the movement of the turning member (11) while the locking part (12) is in the open position; and each safety lock (8) is arranged in the open position of the locking part (12) to allow movement of the turning member (11) and to open the safety lock (8). 7. The locking system (1) according to one of the preceding claims, wherein the safety lock (8) additionally comprises an automatic return element (15) of the locking part (12), which element is arranged to return the locking part (12) to the locked position. 8. The locking system (1) according to one of claims 3-7, wherein the safety lock (8) additionally comprises an automatic return member (16) of the frame (13), which member is arranged to return the frame (13) to the locked position. 9. The locking system (1) according to one of claims 3-8, wherein the safety lock (8) additionally comprises a axle pin (18), which pin is arranged to prevent the axle (13) from opening when the locking part (12) is in the locked position. 10. The locking system (1) according to one of the preceding claims, in which the safety lock (8) comprises a notch (60) in the body (17) of the safety lock (8) and a damping part (62) that can be adapted to it. 11. The locking system (1) according to one of the preceding claims, in which the safety lock (8) comprises a safety lock (8) in the frame (17) to facilitate the installation of the hook (64). 12. Method for opening and closing the element 2 with the help of a locking system (1), which locking system (1) comprises a safety lock (8) on the edge of the element (2) and a locking element (9) on its opposite edge and a tensile stress transmitting element (10) between the casting (8) and the locking member (9), the safety lock (8) comprising the body (17); for unlocking the safety lock (8) and the locking member (9) of the turning member (11); a locking part (12) which is arranged to move between an open and a locked position, which locking part (12) is arranged to prevent the movement of the turning element (11) when the locking part (12) is in the locked position and to allow the turning element (11) to move the locking part (12) in the open position and pressed into the body (17); in which method the locking system (1) allows the movement of the turning member (11) in the open position of the locking part (12), whereupon the member (10) transmitting tensile stress turns at least partially inside the safety lock (8), thereby unlocking the safety lock (8) and the locking member (9).
