Turn-tilt fitting, especially for window sashes or the like.

The innovation relates to a turn-tilt fitting, in particular for window sashes with hinge parts on the frame are connected partly uncoupling with the fitting parts running on the fold side of the sash, the frame side hinge parts being formed by cylindrical plugs which can be inserted from the front side of the frame.

Hinge parts designed as plugs have opposite the conventional hinge parts have the advantage that they facilitate, short-term assembly of the hinge parts on the window frame as well as the window sash on the latter.

The innovation is based on the task of designing a generic tilt and turn fitting so that through advantageous embodiment of the plug parts simplifies the assembly of the window sash to the window frame even more is; Furthermore, a large pivoting range of the window sash is aimed for.

This object is achieved by the invention specified in claim 1. The subclaims provide advantageous refinements this inventive solution.

As a result of such a configuration is a generic one Turn-tilt fitting realized, which in addition to a simplified assembly a large swivel range of the window sash Realized up to 1SO degree. This is what the

the stopper's wings projecting over the surface of the surface, which wings form the insertion openings for the hinged pivot pins penetrating the hinge parts of the window sash. By the one in front of the frame front surface The pivot axis, the driving in of the pivot pins can be accomplished most favorably after merely inserting the window sash into the window frame opening. It just takes on the aligned position of the bearing bores of the hinge parts to the insertion openings for the pivot pins in the stopper to be respected. When the window sash is used, the wings of the plug are preferably so that they end flush with the window sash front surface or lie behind it, so that disturbing projections as far as possible are avoided. In order not to hinder the tilting function of the window sash, the lower pivot pin points on the in the bearing bore of the hinge part entering section on truncated cone shape. The truncated conical pivot pin can be installed in the lower stopper. In order to prevent the pivot pin from entering the bearing bore of the lower one To enable the hinge part is the obliquely backward widening, to the entrance of the free

End of the Scharnisrbandtsilss serving recess on the End face of the lower plug provided. Since the sash side The hinge part carries out the tilting movement of the window sash, widening the free end of the hinge part receiving storage slot towards the rear end of the plug. The one in the bearing bore of the lower hinge part entering pivot pin is in its position against further pressing through the stop collar secured. The top of this stop collar lying flush with the lower wall of the insertion slot does not affect the tilting movement of the window sash in any way. If necessary, the top can be slightly sloping run outwards. As a result of the truncated conical pivot pin is during assembly of the Window sash on the window frame only the upper pivot pin, enforcing the bearing hole of the upper one window sash extxgen hinge part, to be driven into the insertion opening of the sash of the upper plug. For the purpose of Securing the axially immovable position of the stopper, the outer surface of the stopper points into the material of the window frame clawing grooves.

The window designed as a turn-tilt window has the window frame 1 and the window sash 2. The window sash

2 has a drive rod gear (not shown) with an outwardly protruding handle 3. Is the handle 3 after turned down, the closed position is available, see Fig. In the upwardly pivoted position of the handle 3 is located the window sash 2 is in the tilted position and in the position of the handle perpendicular to the closed and tilted position

3 is the rotary position of the window sash 2.

The drive rods 4 and 4 'extend from the drive rod gear. The drive rod 4 ¹ leads via a corner deflection to the tilt lock plate 5 which is attached to the window frame 1 and which interacts with a pin 6 of the drive rod 4 '. The drive rod 4, which is also equipped with corner deflections, carries a locking projection 7 which, depending on the position of the handle 3, is coupled or uncoupled with the strike plate 8. The strike plate 8 sits on the angled end 9 'of an upper scissor link 9, on which a stabilizing link 10 engages. Furthermore, further locking pins 11 are provided on the connecting rods 4,4 ', which correspond to them

Closing plates 12 of the window frame 1 are assigned.

The drive rods 4,4 'lie in a groove 13 of the window sash 2 and are covered by a strip 14.

The window sash 2 can be rotated around the frame-side hinge parts, which are formed by cylindrical plugs 15,16. The latter are in from the front of the frame Milling or drilling made receiving cavities 17 let in the window frame 1.

The plugs 15, 16 have the wings 18, 19 for the pivot pins 20, 21, which project over the frame front surface 1 ' on.

Each stopper 15, 16 carries a grooved central retaining pin 24 or 25, which digs into the wall of the window frame material. The outer surface of the stopper is also grooved, so that the axially immovable position of the stopper is secured.

The upper plug 15 forms a transverse slot 22 penetrating the sash 18 for the entry of the upper, window sash-side Hinge part 23, which is firmly connected to the scissor link 9.

The wing 19 of the lower plug 16 extends below the lower wall 26 'of the insertion slot 26 for the window sash-side hinge part 27 and carries the pivot pin Ζ ^Λ in the insertion opening 21 . This pivot pin 21 has a stop collar 21 'which is supported on the wing 19 and which extends in the area between the cylindrical holding shaft 21 "and the upwardly pointing, frustoconical tapered end 21'". The upper side of the stop collar 21 'is flush with the lower wall 26' of the insertion slot 26 and can optionally be designed to sloping down towards the outer edge of the stop collar so as not to impair the tilting of the window sash. The insertion slot 26 of the lower hinge part plug 16 widens to enable the window sash 2 to be tilted towards the rear end, see FIG. 6. This insertion slot 26 opens obliquely backwards

16. The recess 29 facilitates the assembly of the window sash on the window frame, since the pivot pin 21 is already can be assigned to the plug 16 of the window frame prior to assembly.

The window sash 2 is equipped with the stopper 15, 16 Window frame 1 assigned as follows: In a slightly tilted position, the bearing bore 27 'of the lower, means Screws 30 attached to the window sash hinge part 27 in dis dsn pivot pin 21 overlapping position by virtue of d ^ r Bring recess 29. Then only the upper hinge part 23 on the sash side needs to be inserted into the transverse slot 22 of the stopper 15 to be inserted, whereupon the pivot pin 20 is driven into the insertion opening 31 of the wing 18, while passing through the bearing bore of the hinge part 23 is.

When the window sash 1 is inserted, the wings 18, 19 of the plugs 15, 16 close approximately flush with the window sash front surface 2 ¹ . The wings 18, 19 which protrude above the window edge front face 1 'and which have pivot pins 20, 21
