Abstract

A window or door including a circumferential blind frame and a leaf with a surface element is provided, which can be pivoted about one or more axes in relation to the blind frame, as well as including fittings, located between the leaf and the blind frame, which are used for moving the leaf in relation to the blind frame. Electromechanically actuated locking elements are provided for locking the leaf into the blind frame. Each locking element has its own electromechanical drive, and/or the locking elements are configured such that, when the window is closed, they are displaced in relation to the pane plane, thus pressing the leaf perpendicularly against the blind frame with a predetermined contact force.

Claims

1. An apparatus, comprising:

a blind frame and a leaf, the leaf having a surface element and being pivotable about one or more axis in relation to the blind frame,

fittings operatively arranged between the leaf and the blind frame for moving the leaf in relation to the blind frame;

electromechanically actuated locking elements for locking the leaf into the frame after a closing of the leaf, each of said locking elements having a separate electromechanical drive; and

wherein said locking elements are operatively configured such that, when the leaf is closed, the locking elements are displaced in relation to one another in order to press the leaf perpendicularly with respect to a plane of the surface element against the blind frame with a predetermined contact force.

2. The apparatus according to claim 1, wherein the blind frame and the leaf are components of a window or door.

3. The apparatus according to claim 1, wherein the blind frame is a circumferential blind frame.

4. The apparatus, as claimed in claim 1, wherein the locking elements are configured such that a time period for locking upon closing the leaf is longer than a time period for unlocking prior to opening the leaf.

5. The apparatus, as claimed in claim 1, wherein electromagnetic or electromechanical functional elements are provided for at least one or more of the fittings, for moving the leaf in relation to the blind frame.

8. The apparatus, as claimed in claim 1, wherein each locking element has an electromechanically driven, moveable locking slide, which locking slide engages behind a corresponding immovable locking abutment on at least one of the leaf and the blind frame.

9. The apparatus, as claimed in claim 8, wherein at least one of the locking slides or the locking abutment has a control curve configured for moving, on extending out the locking slide, the stationary locking abutment and, thus, the leaf in the direction of the blind frame, and for locking said locking abutment into the blind frame with the predetermined contact force.

10. The apparatus, as claimed in claim 8, wherein each locking slide has a projection with a predetermined reach;

and that the locking slide is extendable axially so far in the direction of displacement that the stationary locking abutment reaches a position, in which it slides past the projection, whereby the leaf is disengageable from the blind frame.

11. The apparatus, as claimed in claim 1, wherein the electromechanical drive mechanism includes an unlocking spring.

12. The apparatus, as claimed in claim 11, wherein the electromechanical drive mechanism is designed for moving a locking slide for locking and, in so doing, for placing the unlocking spring under tension.

13. The apparatus, as claimed in claim 12, wherein the locking slide and the tensioning of the unlocking spring are carried out by an eccentric arrangement.

14. The apparatus, as claimed in claim 13, wherein the eccentric arrangement includes an eccentric pin, which moves on a circular path.

15. The apparatus, as claimed in claim 14, further comprising a drive housing, which accommodates an electric motor and a gear, and wherein the unlocking spring is a helical spring.

16. The apparatus, as claimed in claim 15, wherein the unlocking spring envelops the locking slide and is braced against two stops, which are moveable in relation to each other and of which one is fixed in position at the locking slide.

17. The apparatus, as claimed in claim 14, wherein the eccentric pin acts on a radial stop on the locking slide, so that, when said eccentric pin moves initially on its circular path for locking, it advances the locking slide outwards out of a drive housing until a position is reached, in which the tension on the unlocking spring may be relaxed for unlocking.

18. The apparatus, as claimed in claim 17, wherein after traversing less than half the circular path of the eccentric pin, the locking position is reached and as the eccentric pin continues to traverse the circular path, the moveable locking slide extends further, until it reaches a position, in which it slides past a head piece at the locking slide with the control curve, so that the leaf may disengage from the blind frame.

19. The apparatus, as claimed in claim 1, wherein at least one of the locking elements is provided on a grip-sided vertical frame strut of the leaf.

20. The apparatus, as claimed in claim 19, wherein one or more of the other frame struts of the leaf has additional locking elements, which lock the leaf point-by-point.

6. The apparatus, as claimed in 1, further comprising a handle, which is disposed on the leaf and includes a grip piece movable into a number of gripping positions on the leaf, said gripping positions corresponding to various operating positions of the leaf,

said handle further including at least one of switching elements and sensors;

wherein the handle is connected wirelessly or by wire to the electromechanically actuated locking elements between the leaf and the blind frame and/or with the electromagnetic or electromechanical functional elements for at least one or more of the fittings.

7. The apparatus, as claimed in claim 6, wherein the handle, including the locking elements and the fittings, is not connected by mechanical elements, the handle being designed for manual opening and closing of the leaf.
