Description

The invention relates to a roof window with a means spring-loaded support arms mounted on the feed box, with the support arms at one end on the top edge of the feed box attached hinged storage, other end about the middle of the wing height with a pivot bearing on the side rail of the wing are articulated, and the wing between the pivot bearing and its top edge on each Side spar with an axle pin is for interaction with a U-shaped cross-section on the side leg the slide rail attached to the feed box, whose cover plate delimiting a groove and adjacent to the wing the pivot in the swing position of the wing overlaps and in the closed position and the swing position of the wing of the journal outside of the Effective area of the cover plate is, after actuation a handle attached to the cross member of the wing when opening the wing by coupling the support arms with the wing of the wing folds around the folding bearings and when opening with the wing uncoupled from the support arms the axle journals in the groove of the slide rail in the direction the lower edge of the feed box move while lifting of the wing-side pivot bearing from the feed box to Swinging of the wing.

In such a known from DE-OS 2 708 785 The roof window is the wing that can be opened in one Folded position or a swing position can be brought. For The wing with the To couple support arms so that the wing synchronized with the support arms attached to it from around the top edge of the feed box arranged folding bearings formed Folding axis moves. The axle journals, which are stationary on the wing are attached, describe a circular arc around the Folding axis. The slide rail on the feed box side is on provide a recess in the upper end so that the Enter or leave the axle journal in the slide rail can. As a result of this recess, the cover plate ends and thus the groove of the slide rail in front of the folding movement area the journal.

Should the sash be released after sash and The pivot remains open, the axle pin remains unchanged in the area of the recess of the slide rail and thus still before the groove opening. Now However, the axle journal opens in the swing position no corresponding information conveyed, so that there is a risk that the journal will slide the slide leave again through the recess and not through the Enter the slot opening into the slot itself and into it slide down as it is to achieve the swing opening of the wing is necessary. To the danger of such incorrect wing opening setting is to be reduced the slide rail with a molded, resilient web provided with the wing uncoupled from the support arms when opening the wing for a swing opening position the axle pins emerge from the slide rail counteract his holding force. For the holding power there is, however, a conflict of objectives, because on the one hand the Entry and exit of the axle journals from the slide rail must allow when folding the wing, on the other hand should prevent the exit if a swing opening of the wing is intended. In addition, e.g. B. depending Arrangement and design of the weight relief device forces when opening the wing act in the sense of lifting the upper area of the wing from the feed box, which then also the resistance exerted by the resilient web easily overcome, causing the wing in an unwanted misuse opening gets into which he uncontrolled around the support arm side Swivel bearing swings.

The invention is therefore based on the object to achieve a generic roof window that the intended opening type of the wing is reliable is obtained.

This task is done with a generic roof window solved according to the invention in that the Axle journal on the side spar of the wing can be moved longitudinally are arranged by in the side rails of the wing mounted drive rods attached are that can be operated by means of a handle Linkage in individual switch positions are relocatable.

The journal is now movable on the Side spars of the wing arranged. By actuation of the handle the axles are moved. It is therefore possible to use the individual positions certain switching positions of the handle to assign the axle journal. In the folding switch position the journal, when lying on the feed box Wings, are z. B. the journal each shortly before the groove opening of the groove Slide rail and therefore outside the effective range the cover plate of the slide rail. When opening it of the wing can then the pivot on the Move the groove past, unhindered by additional forces acting on the journal. If the handle - with lying on the feed box Wing - moved into position for swing opening, the axle journals inevitably in the direction of the lower cross member of the Moved wing, enter through the slot opening Slide rail and get into the groove, so that in the oscillating switch position the axle journals Reach under the respective cover plate of the slide rail. The next time you open the wing, the Do not lift the axle pin off the slide rail. As a result of this locking of the axle journals against lifting off the feed box in connection with lifting the support arms from the wing and from the feed box, at its free end the wing by means of a pivot bearing is articulated, the axles slide inside the groove of the slide rail down until the desired one Swing open position of the wing is reached.

The axle journals can be moved downwards in the groove until it stops at the bottom of the groove reach. The wing is then in the cleaning position, where the outside of the wing from Inside the room is accessible.

So that the respectively set swing opening position of the wing even when exposed to environmental influences is preserved, the wing can be compared to the support arms braked and / or a braking effect between the journal and slide rail, for example due to stiffness, to be used.

With a previously used ROTO "Roto Alpine" roof window FRANK AG, Leinfelden-Echterdingen with swing-swing wing the axle journals are also stationary on the wing appropriate. The wing is equipped with an engagement fitting Mistake. One on the lower, horizontal cross bar of the wing attached handle acts via an expansion gear on two oppositely displaceable connecting rods and one Corner redirection to one in each of the side rails Connecting rod. This drive rod carries near the bottom Cross spar of the wing on the side spar each as Locking tongue designed to interact with a striker attached on the feed box side. The wing can be attached to the casement via bolt link and striker in closed position be locked. Instructs the striker additional Recesses on, the wing is also in folding night ventilation positions fixable in relation to the feed box. At the free end of the wing assigned to the upper edge of the wing Driving rods is a latch piece designed as a snap resiliently mounted for coupling or uncoupling the Wing with the support arms. With just one hand is the locking of the roof window, the setting of folding gap ventilation positions of the wing and the Coupling with and the uncoupling of the wing from the Arms reached.

With such a roof window with one-touch operation it is favorable to add the connecting rods with the journal to connect so that the longitudinal displacement of the Axle journal and its transfer to the individual switch positions done with existing resources can be synchronized with the other locking options via striker and bolt.

The axle journal is preferably on a flange attached in an undercut guide groove one in the side spar of the wing behind the connecting rod inserted base plate is stored and the base plate is equipped with a longitudinal web that a nose helps to reach over the connecting rod in the connection area Driving rod / journal. With that be on the axle loads acting on the flange and the base plate directly in the side rail of the Frame of the wing initiated. The connecting rod is from such burdens kept free, so that the movement the drive rod is not affected. The longitudinal web of the Base plate is used in conjunction with the protruding nose the additional guidance of the connecting rods in the connection area with the journal, the nose this Connection point secures against unintentional lifting the drive rod from which in particular from the flange bent connecting web, which is form-fitting in a Connection recess of the drive rod engages.

The actuation of the handle and thus the setting the different switching positions of the journal and the intended functional sequences for the desired wing opening movement takes place when the feed box is attached Wing. In practice, however, that the handle even with the wing already open accidentally operated. To such a malfunction A misuse protection is excluded in a known manner used, which an actuation of the The handle is completely locked when the sash is open or allows only partial actuation.

A possibility of inactivity can also be consciously considered be taken if it is ensured that this no damage or malfunction to the roof window can occur. Such a device for avoidance the negative effects of incorrect operation the roof window is advantageous in that the cover plate of the groove of the slide rail under Form a slot opening in front of the area of the axle journal in their oscillating switch position that ends on the cover plate a slider is mounted under the action a compression spring protrudes beyond the slot opening almost in the area of the folding switch position of the Journal and that the protruding end of the slider on the top facing away from the groove with a Inclined surface and the bottom parallel to Guide surface of the cover plate arranged for the journal is. Lie with the wings resting on the feed box the axle lock in all three switch positions, Tilt, swing in front of the slot opening on the Slide rail on, so outside the scope of the Cover plate, with the switch position top followed by the switch position and the Switch position swing. The folding opening can unhindered by the slide rail. In the switch position The pivot is probably still outside the groove in front of the groove opening, but engages under the Underside of the pressure-loaded slide. This The bottom forms an extension of the cover plate the slide rail and prevents lifting of the axle journal from the feed box so that the swing opening movement of the wing remains secured. Through the slider becomes the pivot when the wing opens directed downwards and then reaches under the cover plate the slide rail.

If the sash is opened by mistake of the handle the switch position swing of the Axle pin set, hits the following Closing movement of the wing of the journal on one Inclined surface of the slider protruding over the slot opening. The journal exerts a force component on the slide from which the slide against the force of the Press the compression spring back until the axle journeys continue is free and the journal is back on the support the sliding surface of the slide rail is short in the area before the groove opening. Once the force is applied to the Slider is finished by the journal, the Slide out again due to the compression spring, again covers the switch position range swing Axle pin off, which is then caught and secured by the slide is against lifting off the feed box when Opening the wing. This has a negative impact on the skylight even when operated incorrectly of the wing avoided.

In order after pushing back the slider if it is actuated incorrectly Swing switch position of the axle pins the new To make it easier for the slider to overlap, is at the transition from the bottom to the sloping surface arranged a wedge surface of the slide, which the sliding on the one with a round cross-section Axle journal improved.

It is convenient that the slide in one to the slide rail molded housing is mounted and slide rail and slide manufactured as a plastic injection molded part are, so that by the one-piece manufacture of slide rail and valve housing simplify assembly allows inexpensive production of the component from plastic is and at the same time a plastic with the desired Coefficients of friction for the particular Metal existing journal can be chosen.

Fig. 3

in an enlarged scale a section of Fig. 1 in the region of the groove opening of the slide rail.

1 consists of a feed box 1, on which a wing 2 is articulated by means of support arms 3 is. The support arms 3 are at one on the upper end the folding bearing attached to the upper edge of the feed box 4 and at the lower end by means of an approximately wing height center arranged pivot bearing 5 on the respective Side spar 6 of the frame of the wing 2 is articulated. In the area of the upper third of the length of the wing 2 is between the pivot bearing 5 and the upper edge of the wing 2 each side spar 6 has an axle 7 attached to the Interact with one on the front surface of the side leg 8 of the feed box 1 attached slide rail 9 is determined. The slide rail 9 has a essential U-shaped cross section to form a Groove 10 for receiving the journal 7, which is from the the groove 10 delimiting cover plate 11 and so that it is secured against lifting from the feed box 1.

The handle attached to the lower cross member 12 of the wing 2 13 is in three each offset by 90 ° to each other Positions bringable, namely in the closed position, the folding position and the swing opening position. Of the Handle 13 acts on a linkage that is known in the Way of an expansion gear and two counter-rotating Driving rods in the cross member 12, to which there are corner deflections connect the movement to the Side bars 6 of the wing 2 mounted drive rods 14th transfer. Each drive rod 14 carries near the cross member 12 a locking member 15, the one below the slide rail 9 on the feed box 1 assigned a striker 16 is. At the free end of the drive rod 14 is a locking piece 17 resiliently mounted in the form of a snap.

The roof window is in the closed position Wing 2 on the feed box 1 and the locking member 15 is located in the front face of the feed box 1 adjacent closing recess 18 of the striker 16 so that the roof window is locked. In this closed position extends the handle of the Handle 13 parallel to the longitudinal extent of the crossbar 12 of the wing 2. The journal 7 are in the uppermost position, designated V in Fig. 3 is lying on the sliding surface 19 of the slide rail 9.

If the handle 13 is pivoted through 90 °, so that the Handle parallel to the side rails 6 of the wing 2 is aligned, it moves with the drive rod 14 connected journal 7 sliding on the sliding surface 19 down to the position labeled K in FIG. 3 and the locking member 15 is unlocked. The wing 2 can now opened in the dash-dotted lines in Fig. 1 shown folding opening position, for which the Support arms 3 with the wing 2 synchronously around the folding bearing 4 move because the wing 2 by means of the snap-like Bolt pieces 17 in the area of the folding bearing 4 with the support arms 3 are locked. The one present in the journal 7 Direction of movement is indicated in Fig. 3 with an arrow. The axle pins 7 are unimpeded when opening lifted from the feed box 1.

If only a small folding opening movement of the wing 2 causes and the handle 13 in the closed switch position returned, there is a locked folding gap ventilation position of the wing 2 by engaging of the locking member 15 in the gap recess 20 of the Striker 16 with slight lifting off of the journal 7 from the sliding surface 19 of the slide rail 9.

If the handle 13, starting from the closed position, moved by 180 °, so that the handle 13 again extends parallel to the cross member 12, the snap-like Bolt piece 17 retracted by the drive rod 14 and thus the coupling between the wing 2 and the arms 3 lifted, as well as the locking of Bolt member 15 and the journal 7 are down moved to the position labeled S in FIG. 3, where the journals 7 7 are still outside the range of Groove 10 and the cover plate 11 of the slide rail 9 are arranged are, just before the slot opening 21. In this Swing switch position of the journal 7 is the journal 7 overlapped by a slide 22, which in a molded in one piece onto the cover plate 11 of the slide rail 9 Housing 23 is longitudinally displaceable by a compression spring 24.

The free end of the slide 22 projects beyond the slot opening 21. The free end extends over the area of Swing switch position of the journal 7 out to short in front of the area of the folding switch position. The bottom 25 of the slide 22 extends parallel to the guide surface 26 of the cover plate 11, from the bottom the cover plate 11 is formed. The distance between Guide surface 26 and bottom 25 is kept small. The top 27 of the slide 22 goes into an inclined surface 28 over, over the whole, over the Groove opening 21 projecting portion of the slider 22 extends. The travel of the slide 22 is limited by a stop web 29 of the housing 23, the one Elongated hole 30 penetrated in the slider 22. The transition from the inclined surface 28 to the underside 25 of the slide 22 is formed by a wedge surface 31.

After the journal 7 in its swing switching position 3 has reached, the slide prevents 22 when the wing 2 is opened, the axle journal is lifted off 7 from the feed box 1. During the opening movement of the wing 2 uncoupled from the support arms 3 Wing 2 moves around the pivot bearing 5 and the journal 7 slides down on the sliding surface 19. Simultaneously causes the journal 7 to lift the pivot bearing 5 from Feed box 1. With these overlapping and mutually influencing movements Axle journal 7 along the underside 25 of the slide 22, is on the groove opening 21 to the guide surface 26th the cover plate 11 is forwarded and is between the guide surface 26 and sliding surface 19 of the slide rail 9 closely guided. A preferred swing opening width of the wing 2 is shown in Fig. 1 with solid lines.

If the swing-open wing 2 of FIG. 1 on the Gripped upper edge of wing 2 and pressed down, the axles 7 slide along the groove 10 below until they come to rest at the groove end 32, whereby the cleaning position of the wing 2 is achieved in the the outside of the wing 2 accessible from inside the room is.

Is in the opening position of the wing 2 from Fig. 1 actuated the handle 13 by mistake, the Coupling wing 2 / support arm 3 released and the axle pin 7 are moved in the direction of the lower cross member 12. When moving the wing 2 towards the feed box 1 the axle 7 comes into that designated SF in FIG. 3 Position, so in the area of the slide rail 9, short in front of the slot opening 21. The remaining movement on the Feed box 1 too results in hitting the journal 7 on the inclined surface 28 of the slide 22, which is then against the force of the compression spring 24 is pressed into the housing 23 is and thus the way to the sliding surface 19 of the Releases slide rail 9 for the journal 7. The compression spring 24 pushes the slide 22 into its initial position back as soon as the journal 7 passes the slide 22 has and comes to rest on the sliding surface 19 and thereby locks an unwanted with its underside 25 Lifting the axle pin 7 off the slide 9. The axle pin 7 is now in the regular swing switch position and when opening the wing 2 is a correct swing opening position again of wing 2 a.

The slide 22 thus prevents negative effects in the event of incorrect operation of the handle 13 when the handle is open Wing 2.

As can be seen in FIG. 2, which shows a section on an enlarged scale Scale in the area of in the groove 10 of the slide rail 9 arranged journal 7 is in one rebate-open milling 33 a base plate 34 embedded arranged which has an undercut guide groove 35 in which a flange 36 is longitudinally displaceable is mounted on which the steel journal is made 7 riveted or welded. The base plate 34 is with a longitudinal web 37 and with a protruding 38 equipped nose. The nose 38 prevents bending the drive rod 14 under heavy load and secures the connection point between drive rod 14 and Axle journal 7, which is bent out by a flange 36 Connection web 39 is formed, the form-fitting engages in the connecting recess 40 of the drive rod 14.
