The hinge also comprises a lever (10, 11), which is mounted on the hinge bracket (3) in a manner that enables it to pivot about a pivot axis (U) extending parallel to the frame hinge axis (S) and the leaf hinge axis (T), and comprises a detent pawl arrangement (8, 9), which is provided on the frame and leaf hinge parts (1, 2), has cam arrangements (18, 19) that interact with the lever (10, 11), and which causes, depending on the opening angle of the leaf, the pivoting either about the frame hinge axis (S) or about the leaf hinge axis (T). The cam arrangements (18, 19) and the lever (10, 11) are designed so that the lever (10, 11) pivots in a positively controlled manner.

Description

The The invention relates to a tape for a concealed arrangement between the frame and wing in particular a door or a Window of the preamble of claim 1 corresponding type.

Such a band is from the GB 2 203 483 A known. To ensure that the pivoting movements of the hinge bracket at opening angles of the wing to 90 degrees controlled by the Flügelschamierachse, at opening angles> 90 degrees about the Zargenscharnierachse, this band has a pawl arrangement. The latter comprises a lever which is pivotally mounted on the hinge bracket about a parallel to the hinge axes on the hinge bracket.

The Frame and the wing hinge part each comprise a cam arrangement with one of the two End portions of the lever cooperates. The lever comes with a between him and the hinge hanger acting rotational spring acted upon by spring force such that the wing-side End portion of the lever against the cam surface of the cam assembly of wing depressed becomes.

The Cam arrangement of the wing hinge part has a Aufnehmung, in which the wing-side end portion of the lever can reach after reaching about 90 degrees opening position of the wing, wherein As a result, the frame-side end portion of the lever from a recess the cam assembly of the Zargenbandteils disengages and pivoting the hinge bracket around the Zargenscharnierachse releases.

In the from the GB 2 203 483 A Known band is such for the door of a vehicle, in particular for the rear door of a van. Especially for larger and thus heavier wings, such as door or window sash, this tape is not suitable because it does not sufficiently ensure the controlled pivoting sequence of the hinge bracket to the Zargen- and Flügelscharnierachsen.

Of the The invention is therefore based on the object, a generic band develop so that it is also suitable for door or window sash is.

These The object is achieved by the reproduced in claim 1 band.

Thereby, the cam arrangement and the lever are designed in such a way that that a pivoting of the lever is positively controlled, is reliable prevents the lever from disengaging by overcoming the spring force the recess in the cam assembly passes and it to an uncontrolled Swiveling the hinge lever around both hinge axes comes.

By "force-controlled" is meant that the lever over the entire opening path of the wing in guided two pivoting directions of the lever. An unintentional "disengagement" of an end area of the lever from the associated Recess of the cam assembly, as this occurs in particular can, if due to wear of the end portions of the lever in the associated Recess has play or the spring force subsides, is thus excluded.

at a preferred embodiment of the tape according to the invention Means are provided which pivoting of the hinge bracket the Zargenscharnierachse on a certain Zargenschwenkwinkel restrict. By this measure can the band of the invention to certain frames / wing systems be adjusted. It also ensures that a pivoting of the hinge bracket around the Zrgenscharnierachse by a greater than the maximum desired angle impossible is.

at a preferred constructive variant, these means have a provided on the hinge bracket Extension on.

At the Zargenbandteil can then be provided a recess, in which engages the extension and the ends of the Zargenschwenkwinkel limiting attacks for the Form extension.

The Recess may, as is particularly preferred - backdrop-shaped and be formed concentrically with the Zargenscharnierachse. The extension is then in the appropriate distance to the Zargenscharnierachse on the hinge hanger attached and follows between the two longitudinal end portions at Pivoting the course of the scenery.

It has turned out to be useful in most applications, limit the frame pivot angle to a maximum of 90 degrees. at the preferred embodiment Thus, the scenery extends approximately over the length of a quarter circle.

In a particularly preferred constructive variant of the band according to the invention, the cam arrangement of the Zargenbandteils a flat, extending approximately radially to the Zargenscharnierachse stop surface for the front side of the frame-side end portion of the lever. By this measure, it is ensured that when closing the wing in angular areas in which the wing is pivoted exclusively about the wing hinge axis, not to relative movements between the frame-side end portion of the lever and the cam assembly can result in increased wear or jamming.

Around ensure that in this angular range the frame-side End area reliable in engagement with the stop surface remains, the cam arrangement of the frame hinge part has a cam surface, with the wing-side End portion of the lever cooperates, wherein the cam surface in such a way is permitted after reaching the maximum Zargenschwenkwinkels the lever is pivoted so that the frame-side end portion of the stop surface engages behind and the pivoting of the hinge strap the wing hinge axis is released.

Around while closing of the grand piano upon reaching the critical opening angle, at which another closing only by releasing the pivoting movement about the Zargenscharnierachse possible is to release this pivotal movement, the cam surface of the Rahmenbandteils preferably an effective range, the pivot angle of the grand piano around the wing hinge axis limited when closing and when the minimum pivoting angle is reached, the lever is pivoted, that the frame-side end portion out of engagement with the stop is brought. Due to this measure, the pivoting takes place the lever again forcibly controlled.

has the tape according to the invention, as particularly preferred, on both sides of the hinge bracket a Pawl arrangement of the type described, so is the reliability of the band increased and it avoids that the tape by the operating forces of Pawl assembly is loaded unbalanced.

In the drawing is -schematisch- an embodiment of a tape according to the invention shown. Show it:

1 the band with the wing closed;

2 the band at an opening angle of the wing of about 70 degrees;

3 the band at an opening angle of the wing of about 90 degrees;

4 the band at an opening angle of the wing of about 180 degrees;

5 the band during the closing of the wing at an opening angle of about 80 degrees;

6 the band during the closing of the wing at an opening angle of about 70 degrees as well

7 the band after completion of the closing of the wing.

That in the drawing with 100 designated band comprises a on a frame, not shown in the drawing, in particular in a space provided for this purpose in the frame mounting frame Zargenbandteil 1 and a leaf hinge part attachable to a wing also not shown in the drawing, in particular in a mounting space provided in the wing 2 , Furthermore, the band includes 100 a hinge hanger 3 , which is approximately U-shaped.

The hinge hanger 3 is with one end by means of a Zargenbandzapfens 4 on the Zargenbandteil 1 about a Zargenscharnierachse S pivotally mounted. The other end of the hinge bracket 3 is by means of a wing hinge pin 5 on the wing hinge part 2 about a wing hinge axis T, which is parallel to the Zargenscharnierachse S, also mounted pivotally. The hinge hanger 3 contributes to its front and bottom faces shown in the drawing 6 . 7 one to a pawl arrangement 8th . 9 belonging lever 10 . 11 in which the levers are pivotable about a pivot axis U parallel to the frame and the wing hinge axis S, T, in each case by means of a screw defining the pivot axis U 12 , of which only the upper one is shown in the drawing, is attached.

Furthermore, on the front sides 6 . 7 of the hinge strap 3 in each case an extension attached to the zargenseitigem end portion, in turn, in the drawing, only the upstanding extension 13 is recognizable. The extensions are arranged at a radial distance R from the Zargenscharnierachse S and each protrude into a backdrop 14 . 15 into it, each link extending along a Zargenscharnierachse S concentric arc of an angle of about 90 degrees.

The longitudinal ends of the scenes 14 . 15 make stops 16 . 17 for the extension 13 and thus limit the maximum swing angle of the hinge bracket 3 around the frame hinge axis S.

The frame and the wing hinge part 1 . 2 each includes 2 cam assemblies 18 . 19 , each above and below the hinge bracket 3 are arranged. The cam arrangements of the Zargen- or wing hinge parts on both sides of the hinge bracket 3 are similar in their function and mode of operation, so that only the better recognizable in the drawing, shown above cam assemblies are to be described.

The cam arrangement 18 of the Zargenbandteils 1 that together with the lever 10 and the cam assembly 19 of the wing hinge part 2 a pawl arrangement 8th forms, includes a cam surface 20 parallel to the backdrop 14 is on a Zargenscharnierachse S concentric arc extending. The cam surface 20 forms a contact surface for the frame-side end region 21 of the lever 10 , in which this when pivoting the hinge bracket 3 runs around the Zargenscharnierachse S.

As in particular in 2 recognizable, goes the cam surface 20 at its end shown in the drawing on the right about a radially extending to the Zargenscharnierachse S surface having a stop surface 23 for the front end 24 of the frame-side end portion 21 of the lever 10 forms into a depression 22 above.

The cam arrangement 19 of the wing hinge part 2 has a cam surface 25 on, which runs along a concentric to the wing hinge axis T pitch circle. It forms a contact surface on which the wing-side end 26 of the lever 10 expires when the hinge hanger 3 is pivoted about the wing hinge axis T.

The outer contour 29 the wing-side end portion of the lever 10 is arc-shaped convex curved. In particular 3 is removable, the cam surface goes 25 the wing-side cam assembly 19 on the side shown in the drawing on the right in a concave-shaped effective range 27 About, the design of the wing-side end 26 of the lever 10 is adjusted.

The The function of the tape will now be explained with reference to the drawing sequence.

In the closed state of the wing is the extension 13 at the stop shown on the left in the drawing 17 , the convex portion of the wing-side end portion 26 of the lever 10 is in contact with the correspondingly concave effective range 27 that is attached to the cam surface 25 the cam arrangement 19 followed. If now a pivoting movement is initiated by opening the wing on the wing, not shown in the drawing, so first slides the frame-side end 21 of the lever 10 on the cam surface 20 the cam arrangement 18 from. Because a pivoting of the lever 10 around the pivot axis U in the clockwise direction is not possible, the wing-side end portion remains 26 of the lever 10 in the in 1 shown position, thus preventing the hinge bracket 3 can pivot about the wing hinge axis T.

The opening of the wing therefore initially leads to a pivoting of the hinge bracket 3 exclusively around the frame hinge axis S, until the in 2 shown position is achieved by the attachment of the extension 13 at the stop 16 is limited. In this position, the frame-side end portion of the lever 10 no longer on the cam surface 20 but is completely over the depression 22 ,

Especially as a result of 3 becomes apparent, causes a further opening of the wing that the transition area between the cam surface 25 and the concave effective area 27 the cam arrangement 19 at the circular segment-shaped end 28 the wing-side end portion 26 of the lever 10 expires and thus causes a pivoting of the lever in a clockwise direction about the pivot axis U. The result is that the frame-side end portion 21 into the depression 22 engages and touches the stop surface 23 supports, causing the hinge bracket 3 is blocked against rotation about the Zargenscharnierachse S.

Upon further opening of the wing up to an opening angle of 180 degrees, the wing-side end region slides 26 of the lever 10 on the cam surface 25 from, whereby the frame-side end portion 21 in the depression 22 is held.

Will the wing now out of the 4 shown closed 180 degrees opening position, so first finds a pivoting exclusively to the wing hinge axis T instead of the wing-side end 26 back into the concave effective area 27 the cam arrangement 19 engages (cf. 5 ). The sliding of this area on the convex curved outer contour 29 of the lever 10 causes it to be pivoted about the pivot axis U counterclockwise, so that the frame-side end portion 21 the stop surface 23 releases again (s. 6 ). A further closing of the wing then only causes a pivoting of the hinge bracket 3 around the Zargenscharnierachse S, to turn the in 7 shown state of the tape is achieved with the sash closed.
