Abstract

A closure device for connecting two parts with one another includes a first closure part and a second closure part attachable in an attachment direction on the first closure part and has a housing and connection element arranged moveably on the housing along an adjustment direction which differs from the attachment direction. The connection element is attachable to the first closure part in the attachment direction and during attachment is moved in the adjustment direction relative to the housing from a first position into a second position. In a closed position, the connection element is located in the second position and is connected to the first closure part in such that the second closure part is held on the first closure part. The connection element is tensioned in the direction of the first position with respect to the housing.

First claim

The invention claimed is:

1. A closure device for connecting two parts with one another, comprising:
a first closure part;
a second closure part attachable along an attachment direction to the first closure part, closure part comprising a housing and a connection element arranged movably on the housing along an adjustment direction which differs from the attachment direction, and
a display device,
wherein the connection element for closing the closure device is attachable to the first closure part along the attachment direction and during attachment is moved along the adjustment direction relative to the housing from a first position into a second position,
wherein the connection element in a closed position of the closure device is located in the second position and is connected to the first closure part such that the second closure part is held on the first closure part,
wherein the connection element is pretensioned in the direction of the first position relative to the housing,
wherein the display device is arranged on the second closure part and is adjustable, by a movement of the connection element, relative to the housing, the display device being located in a first display position in the first position of the connection element and in a second display position in the second position of the connection element, and
wherein the first closure part comprises at least one first connection portion and the connection element comprises at least one second connection portion, wherein the at least one first connection portion, when the second closure part is attached to the first closure part, is configured to interact with the at least one second connection portion of the connection element, the first connection portion being configured to move the connection element relative to the housing in the adjustment direction during attachment of the second closure part to the first closure part.

2. The closure device as claimed in claim 1 , wherein the connection element is connected to an actuating element such that the connection element is adjustable via the actuating element relative to the housing, wherein the display device is able to be adjusted by adjusting the actuating element.

3. The closure device as claimed in claim 1 , wherein the display device has at least two display fields, a first display field being visible in the first position of the connection element and a second display field being visible in the second position of the connection element.

4. The closure device as claimed in claim 3 , wherein the at least two display fields are arranged on the housing, wherein the actuating element has a recess which is congruent with one of the at least two display fields depending on the position of the connection element and, as a result, makes the respective display field visible.

5. The closure device as claimed in claim 1 , wherein the connection element is held in the closed position counter to the attachment direction and/or transversely to the attachment direction on the first closure part.

6. The closure device as claimed in claim 1 , wherein the connection element is mounted on the housing in a linearly displaceable manner, in a tiltable manner about a tilting axis oriented transversely to the attachment direction or in a rotatable manner about a rotational axis oriented along the attachment direction.

7. The closure device as claimed in claim 1 , wherein the at least one first connection portion and/or the at least one second connection portion are inclined relative to the attachment direction.

8. The closure device as claimed in claim 1 , wherein the at least one first connection portion and/or the at least one second connection portion are extended in a linear manner at an angle obliquely to the attachment direction.

9. The closure device as claimed in claim 1 , wherein at least one of the at least one first connection portion and the at least one second connection portion are formed by at least one thread pitch extended in the adjustment direction.

10. The closure device as claimed in claim 1 , wherein the interaction between the at least one first connection portion and the at least one second connection portion in the closed position is not self-locking, such that when the connection element is under load counter to the attachment direction, the connection element is caused to move relative to the housing counter to the adjustment direction and the closure parts are releasable from one another.

11. The closure device as claimed in claim 1 , wherein at least one first positive connection portion is arranged on the at least one first connection portion and at least one second positive connection portion is arranged on the at least one second connection portion, wherein the at least one first positive connection portion and the at least one second positive connection portion come into positive engagement with one another when the connection element is under load, counter to the attachment direction, and block a movement of the connection element counter to the adjustment direction.

12. The closure device as claimed in claim 1 , wherein the connection element is pretensioned by a spring element relative to the housing.

13. The closure device as claimed in claim 1 , wherein a first magnetic device is arranged on the first closure part and a second magnetic device is arranged on the second closure part, wherein the first magnetic device and the second magnetic device when the closure parts are attached to one another oppose one another in a magnetically attractive manner such that the attachment is magnetically assisted.

14. The closure device as claimed in claim 1 , wherein when the closure parts are attached to one another for closing the closure device, the connection element is magnetically moved in the adjustment direction.

15. A fastening arrangement comprising at least one closure device as claimed in claim 1 , wherein the first closure part is fastened to a first fastening element and the housing of the second closure part is fastened to a second fastening element.

16. The fastening arrangement of claim 15 , wherein the fastening arrangement is a foot mat arrangement.

17. The closure device as claimed in claim 2 , wherein the display device has at least two display fields, a first display field being visible in the first position of the connection element and a second display field being visible in the second position of the connection element.

18. The closure device as claimed in claim 2 , wherein the connection element is held in the closed position counter to the attachment direction and/or transversely to the attachment direction on the first closure part.

19. The closure device as claimed in claim 2 , wherein the connection element is mounted on the housing in a linearly displaceable manner, in a tiltable manner about a tilting axis oriented transversely to the attachment direction or in a rotatable manner about a rotational axis oriented along the attachment direction.
