a holding pin mounted to the holding part; a closure part coupled to a pivot axle, the closure part comprising, an anchoring element comprising a first lateral arm and a second lateral arm, a closing lever axle mounted to the first lateral arm and the second lateral arm, a boundary axle mounted to the first lateral arm and the second lateral arm, a closing lever pivotably mounted to the closing lever axle, a latch axle mounted to the closing lever, a latch having a first latch hole, a second latch hole, a third latch hole, and a latch nose, wherein the latch is mounted to the closing lever axle extending through the first latch hole, the latch is mounted to the boundary axle extending through the second latch hole, the latch is pivotably mounted to the latch axle extending through the third latch hole, and the latch nose is configured to engage the holding pin, a first spring element attached to the closing lever axle, wherein the first spring element is configured to push the closing lever into an open position with respect to the latch, and a second spring element attached to the latch axle, wherein the second spring element is configured to push the latch into a closed position with respect to the anchoring element; and a pivot axle configured to be attached to the industrial truck, wherein the latch is configured to contact the holding pin and deflect at least one of the spring elements, and the closing lever is configured to be actuated and move the latch axle and the pivot axle through a dead center formed with the holding pin and the closing lever is configured to be held in the closed position by the generated clamping force. ### Claim 2 (depends on 1) The closure of claim 1, wherein the latch axle is configured to move through a dead center formed with the holding pin in the closed position by pivoting the closing lever and by further pivoting the closing lever opposite the force of the first spring element and the latch is released from the holding pin. ### Claim 3 (depends on 1) The closure of claim 1, wherein the closure part is configured to mount to a pivotable industrial truck part. ### Claim 4 (depends on 1) The closure of claim 1, wherein the first spring element and the second spring element are identical. ### Claim 5 (depends on 1) The closure of claim 1, wherein the first latch hole is an elongated shape and the closing lever axle is restricted in its movement by at least one end stop. ### Claim 6 (depends on 1) The closure of claim 1, wherein the second latch hole has a circular shape and the boundary axle moves along the circumference of the third latch hole. ### Claim 7 (depends on 1) The closure of claim 1, when the latch nose is configured to engage or release from the holding pin, the boundary axle is no longer in contact with an interior surface of the second latch hole. ### Claim 8 (depends on 1) The closure of claim 1, wherein the closure part is configured to be arranged on a pivotable cover of the industrial truck, wherein the pivotable cover is configured to attach behind the latch on the holding pin when the latch is rotated into the closed position. ### Claim 9 (depends on 1) The closure of claim 1, wherein the closing lever is configured to release the latch from the holding pin after the latch axle has been moved through a dead center. ### Claim 10 (depends on 8) The closure of claim 8, wherein the closure part is configured to be arranged on a battery hood cover of the industrial truck and the closure part is configured to pivot on a bracket, wherein the bracket is configured to allow the latch to engage the holding pin in the closed position of the battery hood cover. ### Claim 11 (depends on 1) The closure of claim 1, wherein the anchoring element has a flat anchoring plate extending between the first and second lateral arms and a raised end section, wherein the anchoring plate at least one bore hole configured to attach the anchoring element to the industrial truck and the raised end section has at least one bore hole configured to adjust a dead center of the closure. ### Claim 12 (depends on 1) The closure of claim 1, wherein a sensor is configured to attach to the holding part at a predetermined distance from the holding pin, which detects engaging and releasing of the latch nose with the holding pin.
