  • Both the window frame and the casement frame are made up of several bars that are attached to one another. Preferably there are four spars, with two of each Holme can be arranged parallel to each other so that together they form a rectangle. In principle, however, other arrangements of the bars can also be implemented.

  • the frame to which the fitting part is attached or at least is intended to be attached has the groove.
  • the groove is designed as a T-groove in one of the spars of the frame.
  • the groove has a cavity which merges into an opening of the groove delimited by opposite groove edges at a distance and via this opens out in particular into an external environment.

  • the mouth opening of the groove lies entirely in a mouth opening plane which runs parallel to the longitudinal central axis of the spar and accommodates the edges of the groove.
  • Perpendicular up the muzzle opening level and the longitudinal center axis is a vertical axis of the spar.
  • a transverse axis of the groove is also perpendicular to the longitudinal center axis and perpendicular to the vertical axis, so that the longitudinal center axis, the vertical axis and the transverse axis span a Cartesian coordinate system.
  • the cavity of the groove has specific dimensions, which can also be referred to as the groove width.
  • the mouth opening of the groove has dimensions in the direction of the transverse axis which are referred to as the mouth width of the groove.
  • the mouth opening width corresponds to the distance between the groove edges delimiting the mouth opening on both sides in the direction of the transverse axis.
  • the width of the mouth opening is smaller than the width of the groove, so that the groove is tapered in the area of the mouth opening, forming the edges of the groove.
  • the fastening device has two gripping elements, namely the first gripping element and the second gripping element. These are designed in such a way that they can be inserted into the groove separately from one another, that is to say at a distance from one another and/or at different times. If, on the other hand, the gripping elements are arranged next to one another, neither insertion into the groove nor removal from the groove is possible.
  • the gripping elements When the fastening device is installed, the gripping elements are inserted into the groove separately from one another and then arranged next to one another. As a result, the gripping elements engage behind the groove edges delimiting the groove and hold the fastening device in the groove.
  • the rear grip elements have the rear grip webs, which when the rear grip elements are arranged on one another in the groove as intended, protrude in opposite directions, namely in particular in the direction of the transverse axis, so that each of the rear grip webs engages behind one of the groove edges and thus the rear grip elements or the fastening device in the Nut holds positively.
  • the rear grip webs run in the direction of a longitudinal center axis of the fastening device, which is preferably arranged parallel to the longitudinal center axis of the groove or the rail.
  • the gripping webs preferably lie in an imaginary plane that runs parallel to the longitudinal center axis of the fastening device or parallel to the longitudinal center plane of the fastening device, which continuously accommodates the longitudinal center axis of the fastening device.
  • the rear-engagement elements should each have an inclined surface, namely the first rear-engagement element should have the first inclined surface and the second rear-engagement element should have the second inclined surface .
  • the inclined surfaces are preferably flat surfaces throughout. The inclined surfaces are designed and arranged in such a way that when the rear-engagement elements are arranged on one another, they come into contact with one another and consequently bear against one another.
  • the gripping elements are additionally pressed against one another in the transverse direction, namely in particular on their inclined surfaces. Due to the static friction of the gripping elements on one another, this creates a holding force which fixes the gripping elements in relation to one another in the direction of the longitudinal central axis of the fastening device. Accordingly, the rear-engagement elements are also reliably held on one another, so that the fastening device and thus the fitting part are reliably prevented from becoming detached from the frame.
  • the inclined surfaces are angled relative to the normal plane.
  • the normal plane is perpendicular to the longitudinal center plane and preferably runs parallel to the longitudinal center axis of the fastening device. This is to be understood in particular as meaning that a respective imaginary plane lying completely in the corresponding inclined surface encloses an angle with the normal plane which is greater than 0° and less than 180°.
  • the angle is particularly preferably greater than 0° and less than 90°, in particular less than 45°.
  • the angle is more preferably at least 5° and at most 40°, at least 10° and at least 35° or at least 15° and at most 30°. Overall, therefore, it is not necessary for the normal plane to actually intersect the respective inclined surface.
  • a separate normal plane can of course be defined for each of the inclined surfaces, which is perpendicular to the longitudinal center plane and also runs parallel to the longitudinal center axis and intersects the respective inclined surface.
  • the described embodiment of the fastening device has the advantage that not only is the fastening device reliably and permanently held on the frame, in particular in the groove of the frame, but also that the gripping elements of the Fastening means are fixed together due to the static friction present between them. Accordingly, an unintentional detachment of the fastening device from the frame cannot occur, rather the rear-engagement elements are held reliably and permanently in the groove.
  • the frame can be made of any material. However, aluminum or an aluminum alloy is particularly preferred as the material for the frame. Such a frame places particularly high demands on the quality of a connection between the frame and the fitting part, since the material thickness of the frame is usually only small.
  • a further development of the invention provides that the first gripping element is fastened directly and the second gripping element only indirectly, in particular via the first gripping element and/or the frame, to a base plate which is larger in the transverse direction for overlapping the groove and for resting on the groove edges Has dimensions than the rear gripping elements that rest against one another via the inclined surfaces.
  • the base plate forms part of the fastening device. It is attached to the first rear grip element, for example it is screwed or riveted to it.
  • the base plate is fastened to the first rear gripping element using at least one screw or at least one rivet, preferably using a plurality of screws, in particular two screws, or a plurality of rivets, in particular two rivets.
  • the fastening device is designed in such a way that the base plate is arranged outside the groove after the insertion of the engagement elements into the groove.
  • the underside of the base plate facing the grip element should rest on the edges of the groove and be supported on them in the direction of the groove.
  • the base plate accordingly has dimensions in the transverse direction or transverse to the longitudinal central axis of the fastening device, which are at least larger than the dimensions of the openings of the groove in the same direction.
  • the base plate has at least the same or even larger dimensions than the groove in the transverse direction.
  • the base plate is particularly preferably designed in such a way that it completely overlaps both groove edges in the transverse direction.
  • the use of the base plate outside of the groove enables a particularly reliable attachment of the fitting part to the frame, since on the one hand the retention of the rear grip elements is improved and on the other hand tilting of the fastening device is reliably prevented overall. It is preferably provided that the first rear gripping element together placed with the base plate on the frame. When the first engagement element is introduced into the groove, it is already fastened to the base plate so that the first engagement element and the base plate are assembled together on the frame. This enables a particularly quick and easy installation, since the arrangement of the two rear grip elements on one another in the groove is significantly simplified.
  • first engagement element has a first form-fitting device and the second engagement element has a second form-fitting device which interacts in a form-fitting manner with the first form-fitting device and which hold the engagement elements together in a vertical direction perpendicular to the longitudinal center axis.
  • the two rear-engagement elements not only interact via the inclined surfaces, but also via the two positive-locking devices, namely the first positive-locking device and the second positive-locking device.
  • the two form-fitting devices interact in a form-fitting manner in order to fasten the gripping elements to one another in the vertical direction in at least one direction, preferably in opposite directions.
  • the positive-locking devices also align the gripping elements in the vertical direction with respect to one another. This ensures in a particularly reliable manner that the sloping surfaces of the gripping elements are permanently in contact with one another and cannot become disengaged in the vertical direction. This configuration of the fastening device further increases reliability.
  • each of the form-fitting devices has a form-fitting web extending from a base body of the respective rear gripping element, the form-fitting webs of the form-fitting devices resting against one another at least at times in an imaginary plane that is arranged parallel to the longitudinal center plane or is angled with respect to it.
  • Each of the rear grip elements therefore has a base body and a form-fitting web. The form-fitting web of each of the form-fitting devices starts from the corresponding base body.
  • the form-fitting webs rest against one another in the vertical direction, so that they are supported against one another in this direction. This achieves the holding of the gripping elements in the vertical direction.
  • the form-fitting webs are in contact with one another in the imaginary plane, so that surface contact between the form-fitting webs is realized and the form-fitting devices and therefore the rear-engagement elements are supported on one another in a particularly reliable manner.
  • the imaginary plane is arranged parallel to the longitudinal center plane, for example. This enables a particularly smooth assembly of the fastening device.
  • the imaginary plane is preferably angled with respect to the longitudinal center plane, ie encloses an angle with it that is greater than 0° and less than 180°.
  • the angle present between the imaginary plane and the longitudinal center plane is at least 5° and at most 30°, at least 10° or at most 20° or approximately or exactly 15°.
  • the imaginary plane is angled in relation to the longitudinal center plane in such a way that a displacement of the gripping elements in the transverse direction towards one another pushes the gripping elements apart in the vertical direction and, conversely, when the gripping elements are displaced in the vertical direction towards one another, the gripping elements are pushed apart in the transverse direction. This achieves an additional clamping or wedging of the rear grip elements against one another, so that they are held together particularly reliably by static friction.
  • a development of the invention provides that the form-fitting web of the first form-fitting device delimits a form-fitting recess together with the base plate, in which the form-fitting web of the second form-fitting device engages in a form-fitting manner in order to hold the rear-engagement elements together in the vertical direction. It is therefore not only provided that the form-fitting webs rest against one another in order to hold the gripping elements against one another in the vertical direction. Rather, the form-fitting recess is in the vertical direction between the base plate and the form-fitting web of the first form-fitting device.
  • the form-fitting web of the second form-fitting device engages in this at least after the mounting of the fastening device on the frame, so that the form-fitting devices are fixed in opposite directions in the vertical direction.
  • the imaginary plane in which the form-fitting webs rest against one another is particularly preferably angled in relation to the longitudinal center plane in the manner already described.
  • the inclined surfaces are formed on the form-fit webs and/or the base bodies as the gripping elements.
  • the sloping surfaces can be designed as desired on the gripping elements, as long as they realize the function already described, namely that they push the two gripping elements apart in the transverse direction if they are shifted towards one another in the longitudinal direction.
  • the inclined surfaces are particularly preferably present at least on the form-fitting webs, namely on their end faces facing away from the respective base body.
  • the inclined surfaces can also be formed on the base bodies or both on the form-fitting webs and on the base bodies. This achieves redundancy between the inclined surfaces.
  • a development of the invention provides that at least one of the inclined surfaces is composed of several inclined surface areas which are spaced apart from one another in the longitudinal direction and, seen in a sectional plane parallel to the longitudinal center plane, run spaced parallel to one another or are aligned with one another.
  • the sloping surfaces are therefore not necessarily present as continuous sloping surfaces, but they can each consist of the plurality of sloping surface areas.
  • Each of the inclined surface areas is particularly preferably flat throughout, ie it is present as a flat surface.
  • the division of the sloping surface into the plurality of sloping surface areas takes place in particular by interrupting the sloping surfaces, for example by an edge, a rounding, a chamfer or the like.
  • the inclined surface areas are spaced apart from one another in the direction of the longitudinal center axis of the fastening device, namely, for example, by at least 40%, at least 50% or at least 60% of an entire extension of the respective rear grip element in this direction.
  • the inclined surface areas are in the same plane, which plane is arranged parallel to the longitudinal median plane.
  • the inclined surface areas are arranged at a distance parallel to one another or are aligned with one another. This means in particular that each of the inclined surface areas lies completely in an imaginary plane and these imaginary planes are arranged parallel to one another or coincide.
  • the respective other gripping element preferably lies with its inclined surface on at least some of the inclined surface areas, particularly preferably on all inclined surface areas. This achieves an excellent support effect in the transverse direction.
  • a further development of the invention provides that the gripping webs of the gripping elements each have a ramp and/or curve running over their entire length have and pass over this into the base body, so that the gripping webs oppose the edges of the groove during assembly of the fastening device and push the fastening device into the groove.
  • the sides of the rear grip webs facing the groove edges do not run continuously flat, but are designed with the ramp or the rounding.
  • the sides of the gripping webs facing the groove edges are continuously flat on their side facing away from the base body, ie they have a flat surface there.
