Definitions

  • the invention relates to a roof window with a locking device for locking in open positions, an opening aid in the form of at least one spring arm running at least in the closed state of the roof window at an acute angle to the feed box, which supports the window sash on the feed box in the opened state.
  • DE-OS 2 422 328 therefore proposes the arrangement of two support levers which hold the opened window in its open position by spring force. These support levers with springs are arranged on the window sash and run with rollers in guide rails on the window frame, with latching thresholds intended to hold the window in a desired position. In this window, however, the bracket is not secure, especially in strong winds. The stopping positions are limited to the notches and the notches lead to jerky movements when opening and closing the window.
  • the invention has for its object to make available a locking device for a roof window of the type mentioned, which guarantees a secure mounting of the window sash in any open position.
  • the spring arm is operatively connected to both the feed box and the window casement via pivot bearings, one of the pivot bearings being located on a spring-loaded slider which can be displaced in a guide and which can be locked by means of a locking device which can be actuated by a handle .
  • An advantage of the solution according to the invention lies in the high ease of use.
  • the window can be opened and closed easily without being affected by stiffness or jerky movements.
  • the window can be securely locked in any position using the handle.
  • the mechanics are protected from the weather and insensitive to dirt. Only a few parts are visible, so that the appearance of the window is not impaired.
  • the locking device can only be arranged on one side of the roof window, for. B. with very small roof windows, or it is arranged on both sides, whereby a higher stability is achieved.
  • the arrangement of the slider it is possible to provide guides with sliders in one or in both side rails of the feed box.
  • the guides with sliders can also be arranged in one or in both side rails of the window sash or they can be accommodated in arms which in turn support the window sash.
  • the window sash is carried by arms and the spring arms are articulated thereon, the sliders being located in guides of the side rails of the feed box.
  • the clamping forces of the locking mechanism are expediently limited in such a way that they come loose before the forces acting on the window sash can lead to destruction.
  • a simple embodiment of the locking device is designed as an eccentric, by means of which the slide can be locked in the guide by means of a handle.
  • Another embodiment of the locking device has a wedge with which the slider can be clamped in the guide. It is useful to insert an intermediate layer between the slider and the wedge, which can be designed such that it extends beyond the region of the guide on both sides in its longitudinal extent, is fastened to one end of the guide and is undercut by the wedge at the other end. Due to the longitudinal displacement of the wedge, the intermediate layer fixes the glider with the specified braking force.
  • This embodiment ensures that the wedge can fix the slider in a variety of possible positions within the guide. For the window, this means that it can be locked in all opening positions. In addition, in this embodiment, it is relatively easy to specify the locking force.
  • a further expedient embodiment consists in that the wedge is displaceable on an inclined plane, the wedge having a length which corresponds at least to the length of the guide, and the inclination of the inclined plane, like the opposite incline of the wedge, has the same pitch angle, so that the wedge surface serving as the clamping surface can be adjusted in parallel by longitudinal displacement of the wedge with respect to the height.
  • the interaction of the wedge and the inclined plane means that the clamping surface can be adjusted absolutely parallel on one Any length can be achieved, while at the same time the clamping force, regardless of the position of the slider, is exactly adjustable.
  • the clamping forces can be increased in that the guide carries a plastic layer on at least one side.
  • the slider carries a rack into which a holding element with at least one tooth can be brought into and out of engagement.
  • the holding element can be arranged on a push rod. If the guide is in a tube, this has, if the push rod extends outside, a recess through which the holding element can enter and exit when the push rod is actuated in order to engage the rack. If the push rod is a resilient push rod, it is possible to press it in the direction of the engagement position by means of a holder.
  • a slope is arranged on the holding element for the exit of the holding element from the recess, which slope advantageously interacts with a chamfering of the recess.
  • the slider can be locked over the entire length of the toothed rack, whereby a locking possibility is achieved in a large adjustment range of the window.
  • the clamping forces can be limited in that the tooth flanks have a relatively flat angle.
  • both the at least one locking device can be actuated from a handle and the closing and opening of the window sash can be carried out.
  • a favorable arrangement is that the handle is located on the lower cross member of the window sash. The power is then transmitted via corner drives and push rods that operate the strikers and are operatively connected to the at least one locking device.
  • the locking device locks the window sash in that the handle is moved from its folded position into its closed position position when the window sash is open.
  • a roof window which, in addition to the folding movement, can also carry out swinging movements in which the window can be pivoted around the suspension on two flared arms.
  • two spring arms are mounted on arms pivotably suspended from the upper end of the feed box, the window sash being rotatably held by the arms and optionally connectable to them.
  • the arms can be locked by the locking device via the spring arms.
  • the window sash can be guided in the grooves of the feed box at the same time by means of two axle journals in order to achieve secure guidance and retention of the window sash.
  • One embodiment provides for the roof window to be designed in such a way that the lock cannot be brought into engagement in this oscillating position, but only in the folding position.
  • a coupling between the handle and locking device is proposed, which is disengaged in the oscillating position.
  • the coupling is designed as a transmission element which has a U-shaped notch into which a pin connected to the push rod engages when the window sash is connected to the arms. If the window sash is brought into the swinging position, the pin moves out of the U-shaped notch of the transmission element and the operative connection is disengaged.
  • the abovementioned tenons can be identical to the axle journals.
  • the arrangement of the axle journals and the grooves then takes place in such a way that the axle journals are in the folded position on a circular arc which runs above an upper opening of the grooves.
  • By adjusting the axle pins they enter the grooves in the oscillating position.
  • the active connection is disengaged as described above.
  • the window sash is closed and in the folded position, it is connected to the arms and the operative connection between the handle and the locking device is established.
  • a lock acts on the handle, through which the handle acts blocked a window sash opened in the swing position is.
  • the window sash is closed, this blockage is removed and the handle can only be moved from its swinging position into the folding position or the closed position in the closed position of the window sash.
  • Fig. 1 shows a skylight in side view, partially in section. The principle of the invention is explained on the basis of this first, simple exemplary embodiment of a locking device.
  • the roof window consists of a feed box 3, which is installed in a roof surface, not shown, and at the upper end of which a window sash 4 is pivotally articulated.
  • This articulation can take place directly or via arms 31, which have a bearing 32 of the window sash 4 at their front end. In the latter case, in addition to the folding movement, the window sash 4 can pivot about the bearing 32, this is the swinging position of the roof window. If such arms 31 are provided, the window sash 4 is firmly connected to the arms 31 in the folded position shown.
  • An opening aid in the form of one or two spring arms 2 acts on the window sash 4 with a force in the opening direction.
  • a spring arm 2 has pivot bearings 5 and 6 at its ends, the pivot bearing 5 being located on the window sash 4 or on an arm 31 and the other pivot bearing 6 lying on a slider 8.
  • the spring arm 2 can perform a pivoting movement in both pivot bearings 5 and 6.
  • the slider 8 is displaceable in a guide 7 and is acted upon by a spring 10 with a force which is imparted to the window sash 4 as an opening force.
  • the guide 7 with the slider 8 and the spring 10 are accommodated in the side member 11 of the feed box 3.
  • such spring arms 2 with the are on both sides of the window sash 4 mentioned elements available.
  • At least one of the sliders 8 can be locked in its guide 7 by means of a locking device 1 by actuating a handle 9.
  • the locking device 1 is designed as an eccentric 12, which is mounted in the side member 11 of the feed box 3 and which clamps the slider 8 in the guide 7 when the handle 9 'is moved in the direction of the arrow.
  • the spring arm 2 can of course also be arranged so that the slider 8 with the spring 10 is housed in the window sash 4 and a simple pivot bearing of the spring arm 2 is arranged on the feed box 3. It is essential that the spring arm 2 extends at an acute angle to the feed box 3, at least in the closed state of the window, so that by moving the slider 8 - while changing this angular position - the window sash 4 can be subjected to a force in the opening direction. Only when the window sash 4 is fully open can the angle of the spring arm 2 to the feed box 3 also be in the region of a right angle.
  • the clamping forces of the locking device 1 are expediently limited in such a way that the locking device 1 releases and releases the slider 8 before the forces acting on the window sash 4 can lead to destruction. This applies both to the locking device 1 described above and to other possible embodiments of the locking device 1.
  • FIG. 2 and 2a show a partial view of a roof window with a second embodiment of the locking device 1.
  • FIG. 2 is a section along an arm 31 and FIG. 2a is the section AB drawn in FIG.
  • the Slider 8 can be clamped in the guide 7 by means of a wedge 13.
  • the guide 7 is located in a tube 25, which can be the essential component of an arm 31.
  • the spring arm 2 engages through a slot 57 in the tube 25 and is connected to the slider 8 there by means of a rotary bearing 6.
  • the pivot bearing 6 is located in a cutout 58 of the slider 8, in which the spring arm 2 engages.
  • a spring 10 is suspended, which acts on the slider 8 with the force supporting the opening of the window sash 4.
  • an intermediate layer 14 is arranged which projects beyond the area of the guide 7 on both sides and at one end, preferably at the end of the tube 25, by means of a fastening 27 to the tube 25 is connected. At the opposite end, the intermediate layer 14 is gripped by the wedge 13.
  • the intermediate layer 14 has a slot through which the arm 2 extends.
  • the slider 8 is pressed against the tube wall by the intermediate layer 14 with a force defining the slider 8. This causes the locking.
  • the tube wall can be provided with a plastic layer 26.
  • Fig. 2a shows a section AB, which is shown in Fig. 2. It can be seen from these figures how the wedge 13 is arranged in the tube 25 and how it presses the intermediate layer 14 against the slider 8 during a movement to the left such that it is fixed to the tube wall. When moving to the right, this application of force to the intermediate layer 14 is reduced or eliminated.
  • the displacement of the wedge 13 is served by a push rod 19 which is in operative connection with the handle 9 and is connected to the wedge 13 through a slot in the tube 25.
  • FIGS. 2 and 2a has the advantage that the slider 8 can be acted upon in a wide range of its possible positions by a predeterminable clamping force and the window sash 4 can thereby be securely fixed in different opening positions.
  • FIG. 2b shows a third locking device, a section being shown which corresponds to the lower part of the section of FIG. 2.
  • the third locking device differs from the second only in this partial area.
  • the wedge 13 is formed in a length that corresponds at least to the length of the guide 7. It is mounted on an inclined plane 63 in such a way that the bevels cancel each other out with respect to the clamping surface 64. The slopes are therefore opposite in the same angle. As a result, the height of the clamping surface 64 can be adjusted in parallel by longitudinal displacement of the wedge 13. In this way, in the area of the entire guide 7, with a predetermined longitudinal displacement of the wedge 13, the slider 8 can be fixed with a specific clamping force that is independent of the position of the slider 8 in the guide 7.
  • Fig. 3 shows a fourth embodiment of a locking device.
  • the slider 8 carries a rack 16, into which a holding element 17, which also carries teeth 18, can be brought into and out of engagement.
  • the holding element 17 is connected to a push rod 19 which can be actuated via the handle 9.
  • the tube 25 is provided with a recess 22, into which the holding element 17 engages in one position and from which it slides out in a second position.
  • the second position is shown in broken lines.
  • at least the part adjoining the holding element 17 is of the push rod 19 is resilient and held by a holder 20, which can be designed, for example, as a rivet or a screw guided in an elongated hole 21 of the push rod 19.
  • the holding element 17 In order to enable the holding element 17 to slide out of the recess 22, the holding element 17 is provided with a bevel 23 and the recess 22 carries a chamfer 24 which interacts with the bevel 23.
  • the toothed rack 16 and the teeth 18 of the holding element 17 can be designed in this way to be flat be that the holding element 17 is pressed outwards under the action of a certain force, whereby the slider 8 can move.
  • the other components correspond to what has been described for FIG. 2, the spring arm 2 having a cut surface, since the locking device 1 of FIG. 3 is shown from below.
  • a milling cutout 58 of the slider 8 into which the spring arm 2 engages can also be seen from below through this viewing direction.

A Such incorrect operation would lead to the locking device 1 no longer being operable. For this reason, the lock 43 engages when the window sash 4 is opened and thus blocks the handle 9, as shown in FIG. 9.
  • Fig. 10 shows the handle 9 in the position in which the window sash 4 assumes the folding position when opened.
  • the push rod end 47 projecting beyond the expansion gear 46 is in a position in which the hook 54 can no longer be gripped by the lock 43 when the window sash 4 is opened.
  • This position corresponds to the representation of the side view of the window in FIG. 11, in which the locking tongues 29 are out of engagement with the locking pieces 30.
  • the axle pins 34 are outside the grooves 35 and the bolts 55 are inserted into the striking plates 56, whereby the window sash 4 is connected to the arms 31.
  • the axle journals 34 are located in the U-shaped notches 38 of the transmission element 37, the holding elements 17 occupying a position in which they are disengaged from the toothed racks 16.
  • the sliders 8 are freely movable, which is necessary for opening the window sash 4.
  • a support for the opening movement is achieved in that the springs 10 apply force to the sliders 8 and the spring arms 2 thereby press the window sash 4 upwards. If the window sash 4 is opened from this position of the functional elements shown in FIG. 11, the situation recorded in FIG. 12 occurs in the area of the lock 43.
  • FIG. 12 shows the area of the lower cross bars 41 and 42 corresponding to FIG. 10 when the window sash 4 is opened.
  • the locking member 49 is again moved downwards by the spring 50, as a result of which the catch 53 lies directly in front of the hook 54 .
  • This adjustment corresponds to the movement of the handle 9 from the folded position (FIG. 12) to the closed position (FIG. 13).
  • the handle 9 cannot be moved into the oscillating position (FIG. 9), since such an adjustment is blocked by the hook 54 pushing against the catch 53 of the lock 43.
  • FIG. 13 shows the aforementioned adjustment of the handle 9 to its closed position with the window sash 4 open.
  • This adjustment of the handle 9 leads to the activation of the locking devices 1, which is explained with reference to FIG. 14.
  • the sliders 8 are initially displaced in the direction of the holding elements 17 (arrow 60). If the handle 9 is now brought into its closed position with the window sash 4 open, the axle pins 34 are displaced via the push rod 19.
  • the transmission elements 37 and the holding elements 17 are entrained in the direction of the sliders 8, as shown by arrow 61.
  • the holding elements 17 enter into the cutouts 22 (FIG. 3) and the teeth 18 of the holding elements 17 snap into the racks 16 of the sliders 8.
  • the window sash 4 is thus locked. This locking can be released by bringing the handle 9 back into its folded position and thereby disengaging the holding elements 17 from the cutouts 22 and thus from the toothed racks 16 of the sliders 8.
  • a locking device 1 according to the embodiment of FIG. 3 was selected.
  • these configurations are also possible with other embodiments of the locking device 1, for example with the locking device 1, as were shown in FIGS. 2 and 2a or in FIG. 2b.
  • These embodiments have the advantage over the embodiment of FIG. 3 that loosening the sliders 8 due to excessive force does not lead to a jerky movement of the window, since these sliders 8 move continuously in the guides as a result of such a force.
