DE1040935B - Opening device for tilt-swivel wing - Google Patents

Description

There are display devices for either a lateral vertical or a lower horizontal one Axis pivotable sash of doors, windows or the like, so-called tilt-swivel sash known, which consists of an extension arm on the upper edge of the sash opposite the horizontal tilt axis exist. The extension arm is at one end outside of the vertical pivot axis on the stationary Articulated frame and slidable at the other end and with a game limited by stops guided on the casement.

In the event of incorrect operation of such a tilt-swivel wing, especially when the joints of the Sash inadvertently unlocked in the vertical swivel axis and in the horizontal tilt axis at the same time the wing can around its lower corner joint within the play of the sliding guide tilt the extension arm on the sash into the interior of the room. The wing must therefore always be raised again to bring the two halves of a joint back into alignment.

According to the invention, the extension arm is arranged on the fixed frame as well as the aforementioned Play dimensioned so that only a simple movement of the wing in a certain position is required to to bring the halves for the joint in the vertical pivot axis back into alignment and thereby to enable mutual coupling of the same. In addition, the size of the game is in the leadership of the The extension arm on the sash frame is approximately equal to the distance between the articulation of the extension arm to make on the fixed frame and the vertical pivot axis of the sash. At around the perpendicular Pivot axis (by about 90 °) fully open sash, this is at the limit stop of the game the articulation of the extension arm on the sash and at the same time align the two halves of the pivot joint with each other or can by pivoting the wing around the articulation of the same on the extension arm be made to flee.

The essence of the invention is even clearer in the description on the basis of a schematic representation described.

FIG. 5 shows a top view of the wing corresponding to FIG. 4, but at the same time this is pivoted in this way is that the hinge parts for the vertical pivot axis on both the wing and the stationary Frame falling into an escape.

The casement frame 11 is articulated on the fixed frame 10 in such a way that it can either pivot about a vertical axis AA or tilt about a horizontal axis 73-5. The upper joint sleeves 12, 13 and the lower joint sleeves 14, 15 connected to the corner joint 16 are used to form the vertical axis AA . The joint sleeves YI, 18 and the corner joint 16 determine the horizontal tilting axis BB.

To limit the tilting, an extension arm 19 is used, which is hinged at one end with a pin 20 on the fixed frame and at its other end has a slot or loop 21 which engages with play over a pin 22 on the sash frame. If the wing is tilted with proper decoupling of the joint sleeves 12 and 13, the left end of the slot 21 rests as a stop on the pin 22, which thus limits the tilting of the wing (FIG. 2).

If, however, the tilting joint 17, 18 is also uncoupled (unlocked) as a result of inattention, so can the wing around the lower corner hinge 16 also fall within the game 21 when the The sash is not yet in the tilt position or remains in this fallen position if the sash is returned to the closed position

should be brought. The wing can then also be moved freely about the axis x-.v, which is determined by the pin 22 and the corner joint 16, since it is only held in the two points 22 and 16.

If the play a _x in the slot 21 (or a play caused by other means in the articulation of the Avisstellarmes on the wing) is smaller than the distance a ₂ between the articulation of the opening arm on the fixed frame and the vertical pivot axis of the wing, the wing cannot can be opened fully to 90 °. If the game O _1, however, is much greater than a ₂ (where a ₂ = zero in the limit case), the wing does not find a stop in the slot when pivoting about the vertical axis AA , even if the wing is in the fully open, z. B. is brought more than 90 ° pivoted position.

According to the invention, the game O _{1 of} the pin 22 in the slot 21 is equal to or approximately equal to the distance α between the pivot point 20 of the extension arm on the fixed frame and the axis of the existing joint sleeve 12, ie the vertical pivot axis AA of the wing. This ensures that in the fully open position of the wing ( i.e. when it is pivoted about 90 ° from the closed position about the vertical pivot axis AA ) the wing rests against the stop in the game, ie the pin 22 at the end of the slot 21, as is shown in FIG. Conversely, there is the possibility of bringing the accidentally double-unlocked wing back into the position properly locked in the vertical pivot axis without any special lifting of the wing being necessary for this purpose. This is done in such a way that the wing is first brought from the position of FIG. 3 by Weitererscliwenken about the vertical axis in the position of FIG. 4, in which the deployment arm 19 is pivoted by about 90 ° or slightly beyond. The wing is then pivoted about the axis XX , the joint sleeve> 13 executing a pivoting movement in the direction of the arrow ν. As soon as the joint sleeves 12 and 13 are again in alignment, the wing can easily be locked again in the vertical pivot axis AA by coupling these two hinge parts, thereby eliminating any additional movement.

If necessary, the play in the articulation of the extension arm on the wing can also be in the direction of the Wing be placed by z. B. the wing has a slot guide in which a pin on Extension arm can slide in the longitudinal direction.
