Definitions

  • the invention relates to a skylight with a feed box, sash and weight balancing device which is formed by at least one gas spring, which has one end formed by the bearing for the eye of the piston rod of the gas spring on the feed box and the other end formed by the bearing of the cylinder of the gas spring on the wing is hinged in each case, the wing being largely automatically opened after its release from the feed box under the influence of the gas spring and, when the piston rod is fully extended, the wing of the gas spring is brought into an emergency opening position in which the opening of the feed box is released from the wing is.
  • the weight compensation device is formed by gas springs , which have a long extension stroke of the piston rod from the cylinder of the gas spring, so that the opening of the feed box is largely released from the wing in the open position of the wing.
  • the angle between the opened sash and the level of the feed box is usually over 90 °.
  • the wing is designed as hinged hinges on a horizontal spar of the feed box or as hinged wings on a longitudinal spar of the feed box.
  • the gas spring can be attached directly to the frame of the wing or indirectly to the wing, namely to a cover that overlaps the wing frame. If the wing is connected to the feed box by means of a subframe, the gas spring can act on the subframe, so that when the wing is fixed on the subframe the wing is opened as a folding wing and after a solution of the fixing of the wing on the subframe around a near the free end of the subframe arranged horizontal axis can be opened swinging.
  • a roof window is known from DE-C 24 22 570.
  • the opening width of the wing is limited in the case of folding sashes and in the case of hinged swinging sashes, the swing-open wing projects into the opening of the feed box and thus limits the clear passage width of the feed box.
  • the opening width of the wing is too large to be able to be used as a roof window, since this means that the wing's opening angle cannot be adjusted for ventilation or viewing purposes which in particular should also be storm-proof.
  • the object of the present invention is to provide a roof window that can be used both as a residential roof window and as an emergency exit, the standard opening of the wing being a viewing opening that is suitable for the roof window and can be converted into an emergency opening position with little effort.
  • a generic roof window in that the cylinder of the gas spring is provided with a sleeve acting as a fixing device on the gas spring, on which a pawl provided with a catch is pivotally mounted and that the catch behind a stop attached to the feed box for limitation the extension stroke of the piston rod can be brought when the wing is unlocked relative to the feed box.
  • the extension stroke of the piston rod of the gas spring can be limited.
  • the distance between the sleeve and thus the cylinder of the gas spring and the stop on the feed box side is fixed and thus the opening of the wing is restricted to an opening angle that is usual in a roof window.
  • the full extension stroke required for reaching the emergency opening position of the wing is thus divided into a partial extension stroke for the usual viewing opening width of a roof window, so that the opening angle between the wing and the feed box can be approximately 30 ° to 45 °.
  • the roof window is therefore suitable as a roof window. Only if access to the roof surface is required, can the fixing device be released by lifting the catch of the latch from the feed box-side stop, whereby the wing then moves into the emergency opening position. After the extension stroke of the piston rod has been limited again by means of the fixing device, the opening limitation of the wing is again given.
  • the fixing device is combined with the gas spring, so that the fixing device is attached to the roof window at the same time as the gas spring is attached.
  • the pivot axis for the pawl is expediently arranged in the area of the sleeve facing the wing, and the pawl is essentially parallel to the piston rod and above the piston rod in that through the longitudinal axis the piston rod extending plane aligned perpendicular to the window plane.
  • the pawl located above the piston rod comes into the coupling position under the influence of its own weight. Starting from the closed position of the window, the pawl is thus always in the ready-for-coupling position when the sash is opened and the sash can only be opened up to a part of the possible opening angle of the sash by reaching behind the catch nose of the catch behind the feed box-side stop.
  • the pawl rests on the eye of the piston rod or on the piston rod and the catch is still at a distance from the wing-side stop.
  • the opening width of the wing increases, the distance of the catch nose from the stop decreases, and when the catch nose comes to rest against the feed box-side stop, the wing opening width is limited.
  • the sleeve carrying the pawl is attached to the cylinder of the gas spring with adjustable length.
  • This length adjustment is achieved in a simple manner in that the sleeve is provided with a longitudinal slot and the longitudinal slot is penetrated transversely by a clamping screw, so that the sleeve can be moved to the desired new opening position of the wing by loosening the clamping screw and in this position by clamping the sleeve on the cylinder of the gas spring can be fixed again by pressing the clamping screw.
  • the stop for the catch nose is formed by the eye of the piston rod or by the bearing assigned to the eye. Then no additional loose components and no additional assembly steps are required for the fixing device, since the fixing device is arranged on the gas spring as a unit and since the bearing for the eye of the piston rod or its eye itself forms the stop; the stop is thus formed by a part that is required anyway.
  • the fixing device In order to bring the sash into the emergency opening position, the fixing device has to be loosened when the sash is open, that is, the catch is disengaged from the feed box-side stop, whereby the full extension stroke of the gas spring is released.
  • This release of the fixing position takes place without an additional aid.
  • the catch of the pawl lies under the influence of its own weight or under the action of an additional load, such as a spring acting on the pawl, on the piston rod and slides along it.
  • the catch nose resting on the piston rod, slides back towards its stop. Since the eye of the piston rod forms a thickening compared to the diameter of the piston rod, a paragraph is given here. So that the catch nose can overflow this paragraph without inhibition, it is favorable to provide the back of the catch nose with a bevel.
  • the pawl To make it easier to lift the pawl out of the fixing position when it engages behind the feed box-side stop with its catch and is under the pressure of the gas spring in this engagement position, it is preferred to provide the pawl with a handle attachment, which makes the pawl easier to grip by hand by the operator.
  • At least the catch lug of the pawl is equipped with a plastic sheath in order to avoid damaging the surface of the piston rod.
  • This sheathing also gives the possibility of dampening the impact when the catch strikes the stop on the feed box side, for example by means of a sheathing made of an elastic plastic.
  • a signal can also be set by coloring the sheathing in order to draw the operator's attention to the respective arrangement of the latch or to the possibility of actuating it.
  • each gas spring is provided with a pawl and that the two pawls are coupled to one another in a movement-locking manner are, so that by actuating only one of the pawls both pawls are lifted out of the fixing position at the same time, or the catches are pressed in simultaneously behind the stop.
  • the gas springs are not visible from the interior of the room when the wing is closed, it is customary to arrange the gas springs in the plane of the longitudinal spars of the feed box, that is to say to fasten a bearing for the gas spring on the end face of a longitudinal spar of the feed box.
  • the gas spring is located in the closed position of the sash on the side next to the sash frame, covered by a sash cover or a subframe likewise overlapping the sash frame, which can also be overlapped by a sash cover.
  • the wing cover is used as a carrier for the second bearing of the gas spring.
  • the gas spring bearings thus mounted in the plane of the longitudinal spar of the feed box have no or only a slight offset from the wing-side to the feed box-side bearing point on which the gas springs act. It is therefore necessary that the operator must exert a great deal of force on the wing at the start of the opening movement of the wing.
  • the wing is therefore preferably provided with a compression spring which interacts with the upper end face of the longitudinal spar of the feed box near the horizontal folding axis of the wing.
  • the compression spring which is preferably designed as a coil spring, is biased with the leaf closed, so that when the closed leaf is unlocked by the spring force of the pressure spring, the leaf is lifted from the feed box until the force of the gas spring then the further opening movement of the leaf supports or takes over.
  • the compression spring is thus used as an auxiliary weight compensation device.
  • a pressure plate is attached to the front side of the feed box as a support surface for the compression spring.
  • a gas spring 5 which is supported by a compression spring 6, serves as the weight compensation device 4.
  • a fixing device 7 is attached to the gas spring 5.
  • the gas spring 5 consists of the cylinder 8, in which a piston arranged on a piston rod 9 is pressurized by means of gas.
  • the gas spring 5 is articulated at one end to the feed box 1, namely in a bearing 10 which is fastened on the end face 11 of the longitudinal beam 26 of the feed box 1, the bearing pin 12 an eye 13 of the piston rod 9 passes through.
  • the other end of the gas spring 5 is fastened to the subframe 3, likewise pivotably in a bearing 14.
  • the cylinder 8 of the gas spring 5 carries a sleeve 15 near its end on the feed box side, which sleeve is provided with a longitudinal slot 16 which is removed from the tensioning screw 17 is crossed.
  • the sleeve 15 In the area facing the wing 2, that is to say above the piston rod 9, the sleeve 15 is equipped with a pivot axis 18 arranged in a horizontal plane, on which a pawl 19 is pivotably mounted.
  • the pawl 19 extends essentially parallel to the piston rod 9 and in a plane extending through the longitudinal axis 20 of the piston rod 9 and oriented perpendicular to the window plane.
  • a catch lug 21 Near the free end of the pawl 19 it carries a catch lug 21 and a handle attachment 22.
  • the active surface of the catch 21 and the ramp 24 are part of a casing 25 made of elastic plastic.
  • the wing 2 In the closed position of the roof window, the wing 2 rests on the feed box 1 and the wing 2 is locked against the feed box 1, the compression spring 6 arranged near the horizontal folding axis 28 of the roof window in the region of the longitudinal bar 26 of the feed box 1 being under tension and the Gas spring 5 is in the pushed-in state of the piston rod 9.
  • the pawl 19 lies under the influence of its own weight on the eye 13 of the piston rod 9, the catch lug 21 being arranged at a distance from the bearing 10 below this bearing 10-side bearing 10.
  • the stored force of the compression spring causes 6 a lifting of the wing 2 about the folding axis 28.
  • a lifting of the wing 2 by a few degrees relative to the plane of the feed box 1 is sufficient so that the articulation points of the gas spring 5 of the feed box-side bearing 10 to the subframe-side or wing-side bearing 14 are displaced more strongly from one another, whereby the force of the gas spring 5 can in turn act more effectively on the wing 2.
  • the pawl 19 slides along the eye 13 of the piston rod 9 in the direction of the bearing 10.
  • the compression spring 6 stands out from its pressure plate 29 on the end face 11 of the feed box 1 and the weight compensation is then carried out exclusively by the gas springs 5.
  • the wing 2 If it is necessary, however, that the living space located under the roof surface should or must be left through the opening of the feed box 1, the wing 2, as described above, must be brought into the opening position shown in dashed lines in FIG. 1 and which corresponds to the opening width customary for roof windows.
  • the pawls 19 are gripped and raised on the handle attachments 22 so that the catch lugs 21 disengage from the stops 27.
  • the fixing of the force of the gas springs 5 is thus eliminated and the gas springs 5 bring about an automatic further lifting of the wing 2 into the emergency opening position shown in solid lines in FIG. 1, the catch lugs 21 running along the piston rods 9.
  • the opening of the feed box 1 In the emergency opening position, the opening of the feed box 1 is largely released.
  • the catch lugs 21 of the pawl 19 slide down on the piston rods 9.
  • the pawl 19 is raised slightly as a result of the ramp 24 of the catch lug 21, glides along the eye 19 or the bearing 10 without pressure and the pawl 19 then falls behind the stop 27 due to its own weight, when the catch 21 has left the area of the eye 13. This results in the limitation of the extension stroke of the piston rod 9 to the viewing opening required for a roof window in an automatic manner, without the need for additional manipulations.
  • the sleeve 15 can be moved longitudinally after loosening the clamping screw 17 on the cylinder 8 of the gas spring 5 and can be fixed again at the desired point by tightening the clamping screw 17.
  • a roof window is thus created, which can be used with a restricted opening width as a roof window with the usual viewing position and which, if necessary, continues to move the wing 2 into an emergency opening position by simply lifting the pawl 19, and which, when subsequently closing, automatically returns to its limit Ausfahrhubes the piston rod 9 arrives, this is done with simple means, a layman-friendly operation is possible and without additional steps in the attachment to the roof window are required.
  • the sleeve 39 which is clamped on the cylinder 8 of the gas spring 5 and is equipped with a longitudinal slot 41, carries a pawl 30 with an approximately U-shaped cross section.
  • the pivot axis 38 of the pawl 30 on the sleeve 39 extends horizontally, namely parallel to the end face 11 of the feed box 1 and is arranged such that the pivot axis 38 extends simultaneously through the longitudinal axis of the piston rod 9.
  • the pawl 30 carries a handle projection 43 protruding from the web 42 of the U cross-section, to which the catch lugs 32 adjoin, which are each formed on one of the legs 31 of the pawl 30.
  • a catch lug 32 extends to both side surfaces 35 of the bearing 34.
  • the stop 33 for these catch lugs 32 is formed by the stubs 37 of the bearing bolt 36 which project beyond these side surfaces 35 and which are engaged by the catch lugs 32.
  • the sleeve 39 carries a spring 40, as can be seen in FIG. 6, which biases on the web 42 of the pawl 30 in the vicinity of the end of the pawl 30 on the pivot bearing side acts. This creates a moment exerted on the pawl 30, which takes effect about the pivot axis 38, which means that the catch tabs 32 cannot unintentionally detach from their stop 33 and that when the wing closes, starting from its emergency opening position, the catch tabs 32 again automatically snap into place behind the stubs 37 of the bearing journal 36 of the bearing 34.
