Device having a hinged cover and at least one flexible element
View Patent ↗The invention relates to a device including a hinged cover, which is pivotable about an axis of rotation out of a closed final position into an open final position, and a flexible element, which acts on the hinged cover with a force along a spring line of action. The flexible element is axially loaded in at least one final position of the cover and is loaded with transverse forces in bending or extension in at least one further position. In the open position of the cover, the spring line of action approaches the axis of rotation of the cover or lies substantially on the axis of rotation of the hinged cover, the spring line of action coincides with the axis of rotation of the cover such that the cover can be fixed in the open final position.
1. An enclosure, comprising a hinged cover which is pivotable about an axis of rotation out of a closed final position into an open final position, and a flexible element which acts upon the hinged cover with a force along a spring line of action, wherein:
the flexible element is axially loaded in at least one final position of the hinged cover and is loaded with transverse forces in bending or tension in at least one further position, and
in the open position of the hinged cover, the spring line of action approaches the axis of rotation of the hinged cover or lies substantially on the axis of rotation of the hinged cover such that the hinged cover reaches a stable self-supporting state in the open final position, or
in the open position of the hinged cover, the spring line of action crosses over the axis of rotation of the hinged cover such that the hinged cover reaches a stable self-supporting state in the open final position, and
wherein the enclosure comprises a blocking surface for acting on the flexible element and the movement of the flexible element is limited by the blocking surface for acting on the flexible element such that a transition point of the flexible element is not exceeded, and/or that the enclosure comprises a blocking surface for the hinged cover with the blocking surface for the hinged cover limiting the movement of the hinged cover such that the hinged cover can not exceed the final open position, and
the flexible element is a leaf spring and at least one end of the spring element is rotationally mounted.
2. Enclosure according to claim 1 , wherein a buckling or extension of the flexible element is required for the hinged cover to pivot out of the closed final position.
3. Enclosure according to claim 1 , wherein the blocking surface for acting on the flexible element is configured as a flange and/or is integrated in a housing.
4. Enclosure according to claim 1 , wherein the flexible element includes one or several corrugations.
5. Enclosure according to claim 1 , comprising an additional unlocking element in which the unlocking element acts upon the flexible element such that the flexible element can be bent out of an axially loaded state.
6. Enclosure according to claim 5 , wherein the unlocking element comprises an unlocking lever and that a pivot joint connects the unlocking element to the hinged cover and/or a housing.
7. Enclosure according to claim 1 , wherein the loading state of the flexible element is modified by inserting another component such that the hinged cover is closed by the spring force of the flexible element.
8. Enclosure according to claim 1 , wherein a part of the hinged cover contacts another part of a housing in the open final position such that a frictional resistance is generated in the open final position or that the hinged cover can be locked in the open final position.
9. Enclosure according to claim 1 , wherein the flexible element acts on the hinged cover over a locking lever and/or that the locking lever acts with a force on another inserted component.
10. Enclosure according to claim 1 , wherein the flexible element comprises a mechanical protection against external influences.
11. A socket covered by a hinged cover device, wherein the cover device comprises the enclosure recited in claim 1 .
