The invention relates to a multi-sash window which can be pivoted about vertical axes Side wings and from the common closing plane horizontally slidable and pivotable middle wing, the top are movably suspended on hangers guided in slots and in guides below to run.

The novelty of the invention consists essentially in the fact that the center of the window Too weak outwardly curved guide slots for the hangers in the upper one The frame part of the window frame is incised and close to the common closing edges the side and middle wing with transverse outward branches and inward bulges are provided. This makes it a little space-consuming and easy upper sash guidance achieved. To prevent the hangers from moving when the center wing is moved Enter the branches or bulges are expediently at the top of the upper frame part opposite the branches and bulges guide rails provided behind which the hangers when driving past the bulges or branches with corresponding thereto grab the attached hook.

On the lower frame part of the window frame are on the common closing edges of the respective wing belonging to one another, the front beveled transverse strips with upstream stops and on the lower, front ends of the respective center wing projections and stops arranged, the serve as a guide for the central wings during the inward pivoting and shifting, wherein An abutment is arranged in the middle of the window, against which the middle sash is Support when pivoting inwards by means of cams attached below. When you move the middle wing, you get them through a groove incorporated at the bottom to guide the beveled crossbars in front of them Attacks so that the center wing can find a good guide when moving both above and below.

The invention is shown in the drawing, for example, in an embodiment on a four-leaf window shown, namely shows

In the drawing, 1 is the two side frame parts, 7 is the upper one and 21 is the one lower frame part (window sill) of the window frame. 2 are the side wings and S are the Slidable and swing-out central wing. In the upper frame part 7, which is expediently is made of hardwood, continuous guide slots 8 are cut, Each of which has an outward branch 9 and an oppositely directed bulge 10 (Fig. 2, 10 and 12). The outer ends of the guide slots 8 are each through in a known manner a metal plate 11 with a Schnepperver closure 12 bounded on the upper side of the upper frame part 7 are attached. Next are on the top of the frame part 7 angle 14 and 15 attached as guide rails, of which the angle 14 den Branches 9 and the angles 15 are arranged opposite the bulges 10. Under 16, 17 and 18 are dotted for each Guide slot three tracks on the top of the frame part 7 indicated. At the underside of the upper frame part is in the closed position of the window sash 5 in known Way, a spring block 19 with a two-legged spring 20 is screwed on. on the top of the window sill 21 is in the closed position of the window sash 5, the abutment 22 arranged. Next are on the top of the window sill near the common closing edge of the belonging together Wing 2, 5 each have a beveled cross bar 23 as a guide piece and this a stop 24 is placed opposite each other. On the windowsill are near the open position the wing board pieces 25 each with an articulated plate 26 attached. The wing 5 is on the lower frame part One piece of hardwood strip 30, in which a groove 31 is cut, is attached (Fig. 5 and 6). The middle wings are each suspended on two hangers 33, 39 (roller carriers). The hanger 33 is guided with its shaft in a screwed onto the upper rear frame part of the wing 5 Spring housing 32, the stroke of the shaft through a guided in the slot 34 Button, 35 is limited. A head is formed at the top of the hanger 33 which a pin 36 and from this a hook

37 protrudes while a roll on it

38 is stored. The other hanger 39 sits firmly by means of the screw-on part 40 on the upper front frame part of the wing 5. On the shaft of the hanger 39 is above Again a head with two pins 41 and 42 is formed, on each of which a roller 43 and 44 is stored. A hook 45 is provided on the pin 41. Next sits on that Lower edge of the wings 5 each have an outwardly projecting projection 46 from which downward directed a further projection 47 protrudes, and on the inner edge each a block 48 with a Bulge curve 49, which are supported against an abutment 22 located in the middle of the window when the sash is pivoted inward. On the underside of each sliding wing is still through groove 31 and stop 24 given the lower guide on the frame part 21.

In order to open one of the middle window sash, the sash is first turned inwards used, wherein the shaft of the hanger 39 leads in the branch 9 inward and the roller 44 runs on the path 16 of the upper frame part 7. At the same time is also the The projection 46 located at the bottom has been brought up to the stop 24. The groove 31 in the Hardwood strip 30, which is attached to the lower window frame, stands with its entrance before the stop 24. Now the window sash pushed to the side, the hangers 39 and 33 run in the slot guide 8, the roller 43 running on the track 18 and the roller 38 on the track 17. The before Bulge 10 lying guide rail 15 is of the on the roller pin 41 of Roll 43 seated hook 45 overlaps, so that the shaft of the hanger 39 is pushed to the side of the central wing cannot enter the bulge 10. At this The window sash 5 also has a lateral displacement at the bottom of the stop 24 and the groove 31 had guidance, the hook 37 seated on the roller pin 36 the

Angle iron 14 overlaps in order to prevent the hanger 33 from entering the branch 9. The projection 47, which is seated at the bottom of the front edge of the window sash 5, has entered the plate 26 and now finds its further guidance here in a known manner. In order to be able to pivot the window sash inwards, the bolt 13 of the snap lock 12 is locked behind the shaft of the hanger 39 so that the sash is securely held when it is pivoted inwards. At the same time, the projection 47 seated at the bottom of the window sash 5 has also entered the lower rotary opening of the plate 26. The rollers 43 and 44 are now on the plate 11 and the roller 38 over the bulge 10. Then the button 35 of the hanger 33 is pulled down, whereby the roller 38 passes through the bulge 10 and the window sash S is free to pivot around. Now the window sash 2 sitting on the fish straps 3 can also be unlocked and also pivoted.
The wings 2 and 5 are closed in the opposite way. At the end of the closing path, the wing 5 is again in the spring bracket 19, 20 and the abutment 22, and it is forced into it by the bottom of the projection 47 with the crossbar 23 and above the hanger 39 engages in the branch 9, whereby the Sash 5 is pushed towards the middle. The number of wings 2 and S can of course be chosen as desired.

The invention can analogously also be applied to double-sash sliding windows. the Bulges 10 can also be carried out inwards, in which case the hangers 33 need not be able to be pulled down.
