Definitions

  • the invention relates to a fitting for slidable doors or windows that is configured to allow rectilinear displacement of a door leaf or a window sash in a direction parallel with the extension plane of the door leaf or window sash, respectively, as well as in a direction perpendicular to this plane.
  • the invention also relates to a system, a sliding door and a sliding window comprising at least one such fitting.
  • Sliding doors such as patio doors, often comprise one or more door leafs that are rectilinearly displaceable between open and closed positions, along a lower rail arranged in a lower frame portion and an upper rail, parallel with the lower rail, arranged in an upper frame portion.
  • the door leaf usually comprises lower and upper sliding door fittings that cooperate with the lower and upper rail to guide the door leaf during its rectilinear displacement along the rails.
  • the lower and/or upper sliding door fittings may comprise wheels resting on the respective rail in order to reduce the friction during said sliding movement.
  • some sliding doors may be arranged so that the door leaf during closing is also displaced perpendicularly to the displacement direction parallel with the rails, i.e., in a direction towards a sealing surface of the door frame.
  • the frame and/or the door leaf may be provided with one or more sealing strips that are compressed during the displacement against the sealing surface such that a good sealing between the door leaf and the frame is achieved.
  • the door leaf When opening the door, the door leaf is first displaced outwardly in a direction away from the sealing surface, so that the displacement parallel with the rails can be performed without friction increasing contact between the door leaf and the frame.
  • the sliding door fittings may here also be configured to, in addition to guide the movement parallel with the rails, also bring about the displacement in a direction towards and away from the sealing surface of the frame.
  • the door leaf may be provided with an espagnolette comprising a, for example with a handle, controllable pull rod connected to the sliding door fitting.
  • the espagnolette may also in a conventional manner be connected to one or more crossbars that in the closed position engage with corresponding edge plates of the frame for locking of the door.
  • a corresponding arrangement and fitting can also be provided for slidable windows.
  • WO 2012/042409 A1 shows an arrangement for slidable doors or windows, comprising an actuating arrangement and a fitting that allows displacement of the door leaf and the window sash, respectively, along two directions perpendicular to each other.
  • the fitting comprises a base member fixed to the door leaf or the window sash that receives an intermediate holder which in turn receives a wheel carrier with two wheels for supporting contact against a rail fixed to a frame.
  • the wheel carrier is rotatably arranged about an axle parallel to the rail, relative to the intermediate holder.
  • the fitting further comprises an actuating bar coupled to the actuating arrangement and that is engaged with an actuating member.
  • the actuating member comprises a protruding part that is received in an oblique activation slot provided in a holder, which is arranged in line with the base member and fixated to the door leaf or the window sash, respectively, and to the base member.
  • the displacement of the actuating member in the oblique activation slot generates a lateral displacement of the actuating member, the holder and thereby the door leaf or the window sash, respectively, in a direction towards or away from the frame.
  • the rotatability of the wheel carrier relative to the intermediate holder allows the wheels to maintain their contact with the rail while following the movement of the fitting and the door leaf or window sash, respectively, in the direction towards and away from the frame.
  • One object of the present invention is to provide an improved fitting for slidable doors and windows.
  • a further object is to provide a fitting with a simple construction and that comprises comparatively few parts.
  • a still further object is to provide a fitting that results in a comparatively low wear on components in the fitting and components cooperating with the fitting.
  • a still further object is to provide a fitting that requires less space and has comparatively small mounting dimensions, in particular a comparatively low mounting height.
  • a still further object is to provide a fitting that results in a good function and maneuverability also with comparatively heavy doors and windows.
  • the fitting according to the invention is adapted to be used with displaceable doors and windows.
  • the fitting comprises a base member configured to be fixated to a door leaf or a window sash that is rectilinearly displaceable in a first displacement direction, along a rail fixated along a frame portion.
  • a guiding member is fixated to the base member and displaceable relative to the base member in a second displacement direction, perpendicular to the first displacement direction, and has a guiding element configured to guidingly engage with the rail.
  • An activation member is connectable with an espagnolette at the door leaf or window sash and configured to bring about the displacement of the base member relative to the guiding member.
  • the activation member is arranged between the base member and the guiding member and displaceable relative to the base member in the first displacement direction and has at least one activation slot.
  • the activation slot extends at an angle to the first displacement direction and cooperates with an activation tap fixated to the guiding member and received in an elongated hole in the base member, extending in the second displacement direction, in order to bring about displacement of the base member relative to the guiding member in the second displacement direction by displacing the activation member relative to the base member in the first displacement direction.
  • the arrangement also results in that the displacement perpendicularly to the length direction of the rail can be accomplished without the need for displacing the guiding member relative to the rail in the second displacement direction, perpendicular to the length direction of the rail.
  • a further advantage with the fitting according to the invention is that the window or the door can be provided with two or more sealing strips arranged outside each other.
  • the fitting allows closing of the door leaf or window sash by first displacing the door leaf or window sash in the first direction and thereafter completing the closing by displacement in the second direction, several sealing strips arranged outside each other can be compressed during the final displacement without these sealing strips preventing or render more difficult the displacement in the first displacement direction. Furthermore, the fitting results in that hook bolts or other locking members that are used to lock the door leaf or window sash do not need to be used for the final tightening to the fully closed position, which is the case for several previously known solutions. Thereby, the wear on such hook bolts or other locking members and the edge plates with which they cooperate, is reduced. Since the activation member is arranged between the base member and the guiding member, a sandwich construction is established with which the dimensions of the fitting, in particular in the length direction of the rail, can be kept comparatively small.
  • the activation member preferably comprises two activation slots, each of which cooperates with a respective activation tap. Thereby, a reliable simultaneous lateral displacement can be achieved along the entire length of the fitting in a simple manner.
  • the fitting preferably comprises at least one wheel that is rotationally journalled to the base member and that extends through a respective wheel opening in the base member, the activation member and the guiding member for supportingly contacting the rail.
  • the base member is preferably displaceable in the second displacement direction relative to the wheel or wheels. In this manner, the need for the wheel to move in the lateral direction relative to the rail during the sideway displacement of the door leaf or window sash, is eliminated. This in turn reduces the wear on the wheels and the rail.
  • the wheel is preferably fixated to an axle displaceable in the second displacement direction, relative to the base member. In this manner, a good guiding of the wheel in its roll direction and sideway displacement of the wheel relative to the base member is achieved in a simple and reliable way.
  • the axle may be fixated relative to the base member, whereby the wheel, and possibly an intermediate bearing, is displaceable in the second displacement direction relative to the axle.
  • the guiding element preferably comprises two protruding guiding bosses configured to receive a part of the rail between them.
  • These fittings are preferably used to guide the lower end of the door leaf or window sash. Then, the fitting can be simply constructed with a load bearing wheel arranged between the guiding bosses to contact the part of the rail between the guiding bosses.
  • This type of fitting is best suitable for rails with an upwardly protruding guide or similar that can be received between the guiding bosses and against which the wheel or wheels can bear.
  • the guiding element preferably comprises a protruding guiding flange configured to be guidingly received in a guiding channel arranged in the rail.
  • a protruding guiding flange configured to be guidingly received in a guiding channel arranged in the rail.
  • Such fittings are suitable for being arranged at the upper end of the door leaf or window sash, where the fittings do not carry the weight of the window leaf or window sash.
  • the protruding flange may be very simply constructed but nevertheless assure an adequate guiding in the length direction of the rail and constitute a reliable support for achieving the lateral displacement.
  • Fittings according to this embodiment are best suitable for rails having an open channel facing the door leaf or window sash, where the channel has two parallel side walls, against which the guiding flange can guidingly engage.
  • the activation slot or activation slots are straight-lined.
  • Such slots may be realized with a very simple machining operation, such as for example a milling operation or similar.
  • Such straight-lined slots consequently contribute to a simple and economically efficient manufacture.
  • the activation slot or activation slots may be curvilinearly formed.
  • the slots may for example exhibit a generally S-formed extension, where the end parts of the both slots extend substantially parallel to the length direction of the rail and an intermediate part extends with an angle of between 15 - 60° in relation to the length direction of the rail, between the both ends.
  • one or both end parts of the rail such that they extend at an angle with respect to the length direction of the rail, where the angle has a sign opposite to the sign of the angle of the intermediate part to the length direction of the rail.
  • the angle of the intermediate part to the length direction may be selected to bring about a desired ratio between the force applied to the activation member in the length direction that is transmitted to a lateral force acting on the door leaf or window by the oblique slots.
  • the angle can be selected so that the required strip pressure is achieved with a desired actuating force.
  • the intermediate part of the activation slot with a variable angle to the length direction of the rail, along the length of the intermediate part.
  • a variable force ratio during the closing and tightening displacement in the second displacement direction of the door leaf or window sash. It may for example be desirable to configure the slot with increasing force ratio in the closing direction so that a relatively low final actuating force on the actuating member generates a relatively high strip pressure.
  • the activation member may comprise at least one coupling portion for connecting with the espagnolette, where the coupling portion is arranged at a centre line of the activation member, which centre line extends in the first displacement direction. Thereby, it is possible to arrange one or more fittings in line and coaxially with respect to a pull rod of the espagnolette.
  • activation member is configured with such coupling portion in each end, several consecutive fittings may be linked by intermediate pull rods.
  • the activation member may comprise at least one coupling portion for connecting with the espagnolette, where the coupling portion protrudes laterally with respect to a centre line of the activation member, which centre line extends in the first displacement direction.
  • Such laterally protruding coupling portion increases the freedom to mount the fitting at an optional position of the door leaf or window sash.
  • this configuration enables the fittings to be placed independently of the placing of the pull rods of the espagnolette. Additionally, in this manner, one single pull rod can be coupled to several consecutive fittings in a very simple way.
  • the activation member is preferably formed from a metal plate. Thereby, a stable and reliable activation member that only slightly adds to the mounting height of the fitting, is achieved.
  • the invention also relates to a system for slidable doors or windows comprising an espagnolette with a manoeuvrable and rectilinearly displaceable pull rod and at least one fitting as described above, connected to the pull rod.
  • the system preferably comprises at least two lower fittings, each comprising at least one wheel, and at least two upper fittings.
  • the pull rod may comprise a flat bar with a generally rectangular cross section arranged edgeways at the side of the fitting.
  • one single pull rod can be coupled to several consecutive fittings.
  • the mounting dimensions in the the lateral direction can be kept small, which enables mounting also in door leafs and window sashes with low thickness.
  • the flat bar preferably comprises a recess in which one laterally protruding coupling portion of the activation member of the fitting engages for connecting the pull rod and the activation member.
  • the invention also relates to a slidable door comprising a door leaf and a door frame having at least one rail, where the door leaf is rectilinearly displaceable along the rail and comprises a system as described above.
  • the invention relates to a slidable window comprising a window sash and a window frame having at least one rail, where the window sash is rectilinearly displaceable in the first displacement direction along the rail and comprises a system as described above.
  • Fig. 1 shows a window comprising a fixed window frame 1, a fixed window sash 2 and an openable window sash 3 that is displaceable relative to the window frame 1 and the fixed window sash 2.
  • the openable window sash 3 is displaceable along a first rectilinear displacement direction that is horizontal and parallel to the general extension plane of the window.
  • Fig. 2 shows the window in a side view, in enlarged scale and Fig. 3 shows the same side view in a more enlarged scale with some parts omitted.
  • a lower rail 4 is fixated to a lower frame portion of the frame 1.
  • An upper rail 5 is in a corresponding way fixated to an upper frame portion of the frame 1.
  • the rails are constituted by elongated profile elements extending in parallel with the general extension plane of the window and in parallel with the length directions of the lower and upper frame portions.
  • the rails 4, 5 consequently have a length axis and a length direction that are parallel to the first displacement direction of the openable window sash 3.
  • the lower rail 4 is arranged below the openable window sash 3 and comprises a guide 4a protruding in a direction towards the window sash and extending substantially along the entire length of the rail 4.
  • the upper rail 5 is arranged above the openable window sash 3 and comprises an open guiding channel 5a facing the window sash 3.
  • the guiding channel 5a has a generally U-shaped cross section with an upper bottom and two facing side walls, substantially perpendicular to the bottom, protruding towards the openable window sash 3.
  • the openable window sash 3 and both rails 4, 5 are arranged generally outside the fixed window sash 2.
  • the openable window sash 3 is consequently located outside the fixed window sash 2.
  • an actuating handle 6 is arranged on the inside of the openable window sash 3.
  • the actuating handle 6 is connected to an espagnolette 7 that extends along the long side and the upper and lower short sides of the openable window in a conventional manner.
  • the espagnolette 7 is shown with an actuating handle 6 but without the openable window sash.
  • the espagnolette 7 comprises a lock housing 8, several pull rods 9, three hook bolts 10 and two upper fittings 20 according to the invention and two lower fittings 40 according to the invention.
  • the hook bolts 10 and the fittings 20, 40 are connected to the lock housing 8 via the pull rods 9 and can be actuated by the actuating handle 6.
  • a fitting 40 according to a first embodiment of the invention is illustrated.
  • the fitting 40 is intended to constitute a lower fitting and to be fixated countersunk in a milled or in other ways prepared recess in a lower end surface of the door leaf or window sash.
  • the fitting 40 comprises a base member 41, a guiding member 42 and an activation member 43.
  • the base member 41 and the guiding member 42 are constructed from an injection moulded polymer material.
  • the activation member 43 is formed from a metal plate.
  • the fitting 40, the base member 41, the guiding member 42 and the activation member 43 are elongated and have a length axis extending in parallel with the length direction of the rail with which the fitting will cooperate.
  • the activation member 43 is arranged between the base member 41 and the guiding member 42 so that the fitting 40 forms a sandwich construction. Thereby, the length and width of the fitting can be kept comparatively low. Due to the formation of the activation member 43 as a relatively thin plate, also the height of the fitting 40 can be kept low.
  • the base member For fixation of the fitting 40 in the recess of the door leaf or window sash, the base member comprises four mounting holes 44 for receiving respective fixation screws (not shown).
  • the orifices (not shown) of the mounting holes 44 facing the guiding member are conical for receiving the screw heads of the mounting screws, so that these do not prevent the movement of the activation member 43 relative to the base member 41.
  • the base member comprises two laterally facing axle apertures 45 for receiving a wheel axle 46.
  • the axle apertures 45 are open in a downward direction, towards the guiding member, for facilitating the mounting of the wheel axle 46. It is however also possible to make the axle apertures cylindrical, for example circular-cylindrical.
  • a wheel 47 is rotatably fixated to the wheel axle 46 by a ball-bearing.
  • the base member 41 comprises a first wheel opening 48, in which the wheel 47 is received.
  • the first wheel opening 48 is wider than the width of the wheel, so that the wheel 47 can be laterally displaced relative to the base member 41.
  • the base member 41 also comprises two elongated holes 49 that are arranged on either side, in the length direction of the fitting, of the wheel opening 48, and that extend perpendicular to the length direction of the fitting.
  • Two pairs of protruding guiding bosses 58, 59 are provided at the base member 41, at a side facing the guiding member 42 (see also Fig. 7 ).
  • the guiding member 42 comprises two guiding bosses 50, protruding downwardly in a direction away from the base member 41, extending in parallel along a substantial part of the length of the fitting.
  • the guiding bosses 50 form a guiding member channel 50a in between them that guidingly receives a part of the guide 4a of the rail 4 when the fitting 40 is mounted.
  • the guiding member 42 also comprises a second wheel opening 51 extending through the guiding member 42 and ending centrally in the guiding member channel 40a.
  • the second wheel opening 51 has a width that substantially conforms to the width of the wheel 47.
  • a circular-cylindrical activation tap through hole 52 is arranged at a centre line, near each of both ends of the guiding member 42.
  • the activation member 43 has a width that substantially conforms to the distance between the guiding bosses 58, resp. 59, in each pair of guiding bosses. Thereby, the activation member 43 is guided to be displaced relative to the base member 41 only in the first displacement direction, while relative displacement between these parts in the second displacement direction is prevented by the guiding bosses 58, 59.
  • the thickness of the plate formed activation member 43 substantially conforms to the protrusion height of the guiding bosses 58, 59. The activation member is thereby guidingly received between the guiding bosses 58, resp. 59 in both pairs.
  • the surface of the activation member 43 facing the guiding member is arranged substantially in the same plane as the end planes of the guiding bosses 58, 59, so that the upper plane of the guiding member can simultaneously contact the activation member 43 and the guiding bosses 58, 59.
  • the activation member 43 comprises a centrally located third wheel opening 53 extending through the activation member 43.
  • the width of the third wheel opening 53 is larger than the width of the wheel 47 so that the activation member 43 can be displaced in the second displacement direction relative to the wheel 47.
  • the length of the third wheel opening 53 is longer than the chords of the wheel extending in the plane of the activation member 43.
  • the activation member 43 further comprises two activation slots 54 extending through the activation member 43.
  • the activation slots 54 are arranged on either side, in the length direction, of the third wheel opening 53. Both activation slots are substantially identically formed and each comprising two end parts 54a, 54b extending substantially parallel with the activation member 43 and thereby the length direction of the fitting 40.
  • An intermediate part 54c connects both end parts 54a, 54b.
  • the intermediate part is in the illustrated example rectilinear and is arranged at a non-zero angle with respect to the length direction of the fitting 40. In the exemplified activation slot 54, the intermediate part 54c is arranged at an angle of about 30° to the length direction.
  • the activation member further comprises a laterally protruding coupling portion 55 with an engagement member 56 that is arranged to engage an opening or other corresponding engagement member of a pull rod of an espagnolette.
  • the base member 41, the guiding member 42 and the activation member 43 are joined by two activation taps 57 that each comprises a head 57a.
  • Each activation tap 57 extends through one respective elongated hole 49, activation slot 54 and activation tap hole 52.
  • the ends of the activation taps are expanded so that the diameters of these ends are larger than the diameter of the respective activation tap hole 52. Thereby, all components of the fitting are joined as one unit.
  • the fitting is in use fixated in a recess in a lower end surface of the window sash 3 of a window door.
  • a rail 4 with an upwardly protruding guide 4a is fixated to the lower frame portion 1.
  • a part of the guide 4a is received in the guiding member channel 50a so that the wheel 47 bears against the upper surface of the guide 4a.
  • the fitting 40 and thereby the window sash 3 are rectilinearly displaceable in a first displacement direction along the rail 4.
  • the window sash 3 is shown when it has been displaced in the first displacement direction to an end position corresponding to a closed position.
  • the lower frame portion 1 comprises a strip part 1a with a first strip channel 1b in which a first sealing strip 1c (see Fig. 3 ) is arranged.
  • the window sash 3 is provided with a second strip channel 3b in which a second sealing strip 3c (see Fig. 3 ) is arranged.
  • the window sash In the position illustrated in Fig. 6 , the window sash is located at a distance from the strip part 1a and the sealing strip.
  • the first strip channel 1b and the first sealing strip 1c are arranged inside of the second strip channel 3b and the second sealing strip 3c.
  • the window sash needs to be displaced against the strip part 1a, in a second displacement direction that is perpendicular to the first displacement direction. This is accomplished by displacing a pull rod 9, connected to the coupling portion 55 of the fitting via the engagement member 56, by the actuating the handle 6.
  • the coupling portion 55 and thereby the activation member 43 should be displaced to the right in the figures to accomplish the closing displacement in the second displacement direction.
  • the activation member 43 is then displaced in the length direction of the fitting 40 relative to the base member 41 and the guiding member. Since the channel 50a of the guiding member 42 guidingly receives the guide 4a, the guiding member will not be displaced in any lateral direction. Also the wheel 47, that is laterally guidingly received in the second wheel opening 51 of the guiding member, maintains its position relative to the rail 4 and the guide 4a.
  • the activation member 43 will, due to the cooperation between the activation taps 57, the activation tap holes 52 and the oblique intermediate parts 54c of the activation slots 54, be displaced towards the strip part 1a in the second displacement direction. Since the activation member 43 is guidingly received between the guiding bosses 58, 59, the base member 41 and thereby the window sash will follow the lateral displacement of the activation member 43. Thereby, a complete closing of the window door is accomplished in a very simple and reliable manner whereby the sealing strips 1c, 3c can be compressed to a desired strip pressure. In the illustrated example, the first sealing strip 1c is compressed between the window sash 3 and the strip part 1a of the frame 1, while the second sealing strip 3c is compressed or deformed by beginning to butt against an inclined surface of the lower rail 4.
  • a particular and essential advantage with the fitting described above is that the wheel 47 during lateral displacement of base member in the second displacement direction does not follow the base member but instead maintains its position relative to the rail 4 and the guide 4a. Thereby, the wear on the wheel 47 and the guide 4a is substantially reduced.
  • a fitting 20 according to a second embodiment is shown.
  • This fitting 20 is intended to constitute an upper fitting and to cooperate with a rail 5 comprising a guiding channel 5a (see Fig. 3 ).
  • the fitting 20 comprises a base member 41, an activation member 43 and two activation taps 57. These components are identic to the corresponding components described above with reference to Figs. 5a, 5b , 6a and 6b and are therefore referred to with the same reference signs also in Fig. 7 .
  • the fitting also comprises a guiding member 142. Since the fitting 20 is intended to constitute an upper fitting, the guiding member 142 is in this embodiment arranged at the top and the base member 41 at the bottom.
  • the activation member 43 is arranged between the base member 41 and the guiding member 142.
  • the guiding member comprises two activation tap holes 152.
  • the guiding member 142 comprises a guiding flange 150 upwardly protruding from its upper side.
  • the guiding flange 150 extends in the length direction of the fitting, along a centre line.
  • the guiding flange comprises an intermediate portion 150a having a lateral width somewhat larger than the width of the remaining portions of the guiding flange.
  • the width of the intermediate portion 150a substantially conforms to the width of the guiding channel 5a in the rail 5. In this manner, the guiding member 142 and thereby the fitting 20 can be displaced along the rail 5 in the first displacement direction parallel with the length direction of the rail 5.
  • the function of the fitting 20 substantially conforms to the function of the above described fitting 40.
  • the only difference is that the guiding flange 150 does not carry any load of the window sash and that it is laterally guided by bearing against the lengthwise interior side walls of the guiding channel 5a.
  • the fitting 20 according to the second embodiment can thereby be said to constitute a further simplification of the fitting according to the invention.
  • a particular advantage with the fitting 20 according to the second embodiment is that all included components except the guiding member 142 can be identic to the corresponding components of the lower fitting 40. Thereby, manufacture, warehousing and mounting is considerably facilitated while the costs associated with these moments are reduced.
  • an upper first sealing strip 1c' is fixated to the upper frame portion of the frame 1 and an upper second sealing strip 3c' is fixated to the window sash 3.
  • the upper sealing strip 1c' is compressed and the upper second sealing strip 3c' will begin to butt against a strip support 5c arranged on the upper rail 5.
  • first sealing strips are arranged on the frame and the second sealing strips are arranged on the window sash. It should however be realized that one, two or several sealing strips may be fixated either on the frame or on the window sash or door leaf.
  • a fitting 220 according to a third embodiment is illustrated. Also this fitting 220 is intended to constitute an upper fitting and comprises a base member 41, a guiding member 142 and activation taps 57 that are identic to the corresponding components of the fitting in Fig. 7 .
  • the fitting in Fig. 8 differs from that in Fig. 7 in that the activation member 243 comprises two coupling portions 255 centrally located at a respective end of the activation member 243. Both coupling portions 255 protrude in the length direction and are provided with coupling holes 256 for connection with a respective pull rod of an espagnolette.
  • the fitting 220 according to the third embodiment is fixated in a recess that is concentrically arranged with a pull rod channel in the window sash or window leaf. Due to the provision of coupling portions 255 at both ends of the activation member 243, the actuating motion of the espagnolette can be easily transmitted to several consecutive fittings in line, by pull rods arranged between the fittings.
  • the activation member of the fitting comprises both laterally protruding coupling portions of the type or similar type as shown in Figs. 5a and 5b and lengthwise protruding coupling portions of the type or similar type as shown in Fig. 8 .
  • Such configured fittings result in that one single fitting can be used in installations both where the fitting is arranged in line with the pull rod or pull rods and in installations where the fitting is arranged next to the pull rod or pull rods.
  • the upper fitting 20 is shown mounted to a window sash 3.
  • the fitting is here maneuvered by a pull rod 109 extending at the side of the fitting.
  • the pull rod 109 exhibits a rectangular cross section and is received in an elongated pull rod channel 3a that is arranged in the window sash 3.
  • the pull rod is edgeways oriented in the pull rod channel 3a.
  • the pull rod comprises several coupling holes 109a (only one shown) evenly distributed along the length of the pull rod 109.
  • the laterally protruding engagement member 56 of the fitting 20 is received in one of the coupling holes 109a so that the activation member in this manner is connected with the pull rod and the espagnolette in which it is included.
  • This embodiment entails a very simple and reliable connection between the fitting 20 and the pull rod 109. Due to the pull rod 109 being arranged edgeways, the installation further requires only a relatively small space in the lateral direction of the window sash 3. This constitutes a considerable advantage for thin window sashes. Furthermore, with this embodiment it is possible to produce the pull rods with standardized lengths and later during the assembly on the window sash or door leaf cut the pull rod to a suitable length. The positioning of one or several fittings along the window sash or door leaf may then be adapted so that the laterally protruding engagement members coincide with the coupling holes 109a of the pull rod.
