Description

The invention relates to a window or door fitting with at least two arranged on a Falzumfangsfläche a window or a door sash, which are adjacent to each other at longitudinal ends and connected to each other, wherein at the longitudinal end of the first faceplate with the second faceplate in the longitudinal direction overlapping connecting strap is provided.

Such a fitting is described in DE-A-29 25 671 , In this case, one of two mutually adjacent cuff rails is provided with a connecting tab in the form of a hook which is to be brought into engagement with a corresponding hook counterpart at the associated longitudinal end of the other cuff rail. The resulting and in the longitudinal direction of the faceplate, ie parallel to the respective wing peripheral surface, effective hook connection is covered wing frame side of the housing of a corner and on the side opposite the casement side of a Ausklinkungslappen the second faceplate. In this way, the hook on one and the hook counterpart on the other faceplate in the transverse direction of the faceplate or the Falzumfangsfläche be secured against loosening. Overall, an effective connection of the two cuff rails results both in their longitudinal and in their transverse direction. To produce this connection, the two cuff rails are biaxial, namely initially in Stulpschienenlängs- and then in Stulpschienenquerrichtung to move against each other. Automatically, the previously known cuff rails can therefore be interconnected only with difficulty.

To further develop the state of the art in this regard, the present invention has set itself the goal.

According to the invention, this object is achieved in that, in the case of a window or door fitting of the type mentioned at the connecting tab of the first and on the overlapping with the connecting tab region of the second face plate on the one hand at least one perpendicular to the Falzumfangsfläche projecting connecting projection and on the other hand at least one in the use position the connecting rail is elastically deformable at least in a partial area parallel to the Falzumfangsfläche and in the undeformed state has an excess over the connection receiving and wherein the connecting projection with appropriate elastic deformation in the connection receiving perpendicular to the Falzumfangsfläche insertable is. By a rectilinear relative movement perpendicular to the Falzumfangsfläche can be according to the invention, the two cuff rails together. The automation of fitting part assembly, in particular the control of assembly aids requires due to the simple kinematics of the assembly movement only a small effort.

In a preferred embodiment of the invention, the connecting strap of the first face-plate is arranged on the side facing the window or the door side of the second face-plate and approximately to the thickness of overlapping with their region of the second face-plate perpendicular to the Falzumfangsfläche sold off the window or the door. Because of these measures, a substantially offset-free course of the adjoining Stulpschienenflächen results on the remote from the window or the door leaf and the associated frame facing side.

In particular, the compensation of manufacturing and / or assembly tolerances it serves that the connecting projection is mounted floating in the case of a further variant of the invention on the connecting plate of the first face-plate or on the second face-plate parallel to the Falzumfangsfläche.

An automatic mutual alignment of connecting projection and connection recording or of first and second faceplate in the desired position is achieved in that the connecting projection has at least one guide surface on which the edge of the connection receptacle during insertion of the connecting projection in the connection receiving parallel to the Falzumfangsfläche is supportable.

The holding force required for the connection of the two adjacent cuff rails according to the invention is effected by different, individually or collectively realizable structural measures. Thus, in the context of the invention, it is provided that the connection projection in the use position the cuff rails on the second cuff rail or on the connecting strap of the first cuff rail is elastically clamped parallel to the Falzumfangsfläche and / or that the connecting projection - when attached to the connecting tab - the second face plate on their side remote from the connecting tab or - when attached to the second Faceplate - the connecting plate at its side remote from the second cuff rail side parallel to the Falzumfangsfläche engages behind a form fit.

In the interest of a low production and cost of the connecting projection is formed in the case of a further preferred embodiment of the invention of at least two spring arms held on the connecting strap of the first face-plate or on the second face-plate spring clip, wherein the spring arms parallel to the Falzumfangsfläche against the action of a elastic restoring force are movable relative to each other.

In a structurally simple manner, such a connection projection or can be such spring arms attach to the relevant faceplate when - as the invention also realized - the spring arms provided on a cross-sectionally substantially C-shaped base of the spring clip and by means of the base the spring clip on the connecting tab of the first faceplate or on the second Faceplate are held, wherein the base of the spring clip surrounds the connecting tab of the first faceplate or the second faceplate and the spring arms project from the base of the spring clip perpendicular to the Falzumfangsfläche.

For the purpose of a floating mounting of the spring arms parallel to the Falzumfangsfläche the spring clip is guided with the spring arms in a further development of the invention by means of the C-shaped base on the connecting plate of the first face-plate or on the second face-plate in Stulpschienenlängsrichtung.

In the transverse direction of the Falzumfangsfläche or the face plate, the spring clip according to the invention is held on the face-plate over its C-shaped base. The support of the spring clip in Stulpschienenlängsrichtung serve in a preferred embodiment of the invention in this direction effective stops for the slidably guided spring clip on the connecting plate of the first face-plate or on the second face-plate.

Especially proven FIG. 1 a curb rail 1, 2 serve in a known manner to cover a fitting part 3 in a Falzumfangsfläche 4 of a window sash 5 FIG. 3 ).

The first faceplate 1 is bent at right angles and at its in FIG. 1 down facing end provided with a connecting tab 6. The connecting plate 6 is formed with a bend to the first faceplate 1 and approximately to the Thickness of the overlapping with her area of the second face-plate 2 perpendicular to the Falzumfangsfläche 4 to the window sash 5 out down. The width of the connecting plate 6 is less than the width of the cuff rails 1, 2. As a result, the connecting plate 6 on the underside of the faceplate 2 in the fitting part 3 immerse, while the faceplate 2 itself is mounted on a gradation of fitting part 3 ( FIG. 3 ). An embossed as embossment 7 of the connecting plate 6 projection projects from the underside and forms with an end face 8 effective in Stulpschienenlängsrichtung stop for a spring clip 9 (among others FIG. 2 ). A stop 15 for the spring clip 9 in the form of two resulting as a result of a width graduation of the connecting plate 6 step surfaces is effective in the cuff rail opposite direction (Figure 4).

The spring clip 9 has a C-shaped base 10, on which it is slidably held on the connecting plate 6 in Stulpschienenlängsrichtung. Of the C-shaped base 10 of the spring clip 9 are perpendicular to the Falzumfangsfläche 4 spring arms 11 with hook ends 12 before ( Figures 3 . 5 ). At their located in Stulpschienenlängsrichtung boundaries, the spring arms 11 are chamfered to form guide surfaces 13. In the base of the C-shaped base 10 of the spring clip 9, a window-like opening 14 is recessed, which receives the embossment 7 of the connecting plate 6 and against this both has an oversize in Stulpschienenlängs- as well as in Stulpschienenquerrichtung. Because of this excess, there is a floating support of the spring clip 9 on the connecting plate 6. The possible deflection movement of the spring clip 9 is limited in Stulpschienenlängsrichtung on the one hand by the end face 8 of the embossment 7 and on the other hand by the stop 15 on the connecting plate 6.

The spring arms 11 of the spring clip 9 are parallel to the Falzumfangsfläche 4, namely in Stulpschienenquerrichtung, against the action of an elastic restoring force against each other movable and thus form an elastically deformable in said direction connecting projection on the connecting plate 6. In use position of the cuff rails 1, 2 enforce the The elongated hole 16 is bounded in Stulpschienenquerrichtung by longitudinal walls 17 which extend inclined to the normal to the Falzumfangsfläche 4 ( FIG. 3 ). In the undeformed state of the spring arms 11, the distance between the free spring arm ends in Stulpschienenquerrichtung exceeds the corresponding dimension of the elongated hole 16 on the face plate 2. Accordingly, the formed by the spring arms 11, undeformed connection projection in the direction mentioned in excess of the slot 16 on the second face-plate 2 on.

As part of fitting assembly, as in FIG. 3 is indicated, the second faceplate 2 is mounted in a mounting direction 18 perpendicular to the Falzumfangsfläche 4 of the window sash 5 on the on the connecting plate 6 of the previously arranged on the window sash 5 first faceplate 1 pre-assembled spring clip 9. In this case, the second face-plate 2 initially runs with the longitudinal walls 17 of the oblong hole 16 on the hook ends 12 of the spring arms 11 on the spring clip 9. With continued movement of the second face-plate 2 in the mounting direction 18, the spring arms 11 are pivoted toward each other against the action of an elastic restoring force. As soon as the second face-plate 2 has passed with its upper side the free spring arm ends, the spring arms 11 spring back into their starting position, in which they - as in FIG FIG. 3 shown with solid lines - the second face-plate 2 at its side remote from the connecting tab 6 side parallel to the Falzumfangsfläche 4 engage behind a positive fit. If the two cuff rails 1, 2 are arranged correspondingly relative to one another in the cuff rail length direction, one of the transverse walls of the elongated hole 16 located in the cuff rail longitudinal direction runs on the associated guide surfaces 13 on the spring arms 11 during the described assembly process. In the interaction of the relevant transverse wall of the elongated hole 16 and the associated guide surfaces 13 on the spring arms 11, the spring clip 9 and the first faceplate 1 and the second faceplate 2 with their movement in the mounting direction 18 in Stulpschienenlängsrichtung automatically aligned with each other. To release the connection of the cuff rails 1, 2 obtained, the spring arms 11 are to be pivoted inwardly before the second cuff rail 2 can be lifted off the first cuff rail 1 or from the connecting plate 6.

The in FIG. 6 shown window fitting differs from the embodiment described above essentially by the formation of spring arms 111 a spring clip 109. Unlike in the case of the spring arms 11 of the spring clip 9, the free ends of the spring arms 111 are at hook ends 112 facing each other. As a result, the second face-plate 2 is not engaged behind the form-locking manner in the position of use on the first face-plate rail 1 or its connecting tongue 6 by the spring arms 111 but held in a clamping manner. To release the connection between the cuff rails 1, 2, the second cuff rail 2 can therefore simply be deducted from the spring clip 109 and their spring arms 111 in the opposite direction of the mounting direction 18.

In the case of both fitting types, the cuff rails 1, 2 can be effectively fixed to one another in the mounting direction 18 by means of a linear movement, which consequently can be carried out automatically without further ado. To secure the connection thus obtained, the cuff rails 1, 2 can be screwed in addition to the window sash 5 in a known manner.
