Closure device that is secured when loaded
Provided is a closure device including a first closure part that includes a locking element, a force transmission element operatively connected to the locking element, which can be loaded along a force direction, and an actuating element movable relative to the locking element, and a second closure part that includes an engagement element. The locking element and the engagement element can be attached to each other for connecting the first closure part and the second closure part to each other and are connected to each other in a closed position. In the closed position, when the force transmission element is loaded along the force direction, the locking element is loaded in a locking direction towards contact with the engagement element by the action of force of the force transmission element. The actuating element can be actuated in order to adjust the locking element against the locking direction.

a first closure part that includes a locking element, a force transmission element operatively connected to the locking element, which can be loaded along a force direction, and an actuating element movable relative to the locking element, and
a second closure part that includes an engagement element, wherein the locking element and the engagement element can be attached to each other for connecting the first closure part and the second closure part to each other and are connected to each other in a closed position,
wherein in the closed position, when the force transmission element loaded along the force direction, the locking element is loaded in a locking direction towards contact with the engagement element by an action of force of the force transmission element,
wherein the actuating element can be actuated in order to adjust the locking element against the locking direction for releasing a connection between the locking element and the engagement element, and
wherein the first closure part includes a first magnetic element and the second closure part includes a second magnetic element, and wherein the first magnetic element and the second magnetic element cooperate in a magnetically attracting way when the locking element and the engagement element are attached to each other.
2. The closure device according to claim 1 , wherein the force transmission element is formed by a traction element that can be subjected to a tensile load.
3. The closure device according to claim 2 , wherein the force transmission element is configured flexurally slack for transmitting exclusively tensile forces.
4. The closure device according to claim 1 , wherein the force transmission element includes an acting portion which at least sectionally is circumferentially extended around the locking element.
5. The closure device according to claim 4 , wherein the acting portion is formed by a loop.
6. The closure device according to claim 1 , wherein the first closure part has a housing relative to which the locking element is elastically adjustable.
7. The closure device according to claim 6 , wherein the actuating element is force-loaded relative to the housing in the direction of a non-actuated position.
8. The closure device according to claim 1 , wherein the first magnetic element is arranged on the actuating element and is movable together with the actuating element on actuation of the actuating element.
9. The closure device according to claim 1 , wherein the locking element includes an elastically deformable elasticity portion and at least one leg arranged on the elasticity portion, which can be brought in contact with the engagement element.
10. The closure device according to claim 9 , wherein the force transmission element is operatively connected to the at least one leg for loading the at least one leg in the locking direction.
11. The closure device according to claim 9 , wherein the at least one leg includes a rope groove for receiving the force transmission element.
12. The closure device according to claim 9 , wherein the actuating element includes an actuating portion which on actuation of the actuating element acts on the at least one leg in order to adjust the at least one leg against the locking direction for releasing the connection between the locking element and the engagement element.
13. The closure device according to claim 1 , wherein the actuating element can be actuated along an actuating direction that is directed perpendicularly to the locking direction.
14. The closure device according to claim 1 , wherein the locking element includes a locking portion which in the closed position positively is in engagement with the engagement element.
15. A system, comprising a useful assembly and a closure device according to claim 1 , wherein the useful assembly is connected to the force transmission element.
16. A system, comprising a useful assembly and a closure device, which includes a first closure part with a force transmission element loadable along a force direction, which is connected to the useful assembly, and a first magnetic element, and a second closure part with a second magnetic element, wherein the first closure part and the second closure part can be attached to each other, are connected to each other in a closed position and can be released from each other for opening the closure device, wherein the first magnetic element and the second magnetic element cooperate in a magnetically attracting way when the first closure part and the second closure part are attached to each other, and
