Description

The invention relates to a window or door fitting with at least two can be 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 cuff rail with the second cuff rail in the longitudinal direction overlapping connecting strap is provided and wherein at least one perpendicular to the Falzumfangsfläche projecting connecting projection and on the other hand at least one in the position of use of the cuff rails of the connecting projection interspersed connection receiving is provided on the connecting tab of the first faceplate and on the overlapping with the connecting tab region of the second faceplate.

Such a window or door fitting is disclosed in DE 32 45 671 A1 as in DE 2 224 499 A ,

According to DE 32 45 671 A1 For example, a cuff bar drive rod assembly is assembled from two subunits. A first subunit comprises a first cuff rail on which a receiving opening is recessed and which has an angling with an angle leg extending perpendicular to the cuff rail at the end remote from the receiving opening. At the angle leg is parallel to the first faceplate, a locking projection before. A second faceplate of the second subunit has, at its end facing the first cuff rail, a connecting lug with a detent receptacle associated with the detent projection of the first cuff rail. In addition, a Eckumlenkungsgehäuse is fixed to the second faceplate, in its remote from the second cuff rail end a Verrastungsteil is inserted with a protruding to the first cuff rail latching hook. To mount the cuff rail espagnolette unit, the latching hook of the latching part connected to the second cuff rail via the corner deflecting housing is first inserted into the receiving opening on the first curb rail. Subsequently, the first face-plate is displaced in its longitudinal direction relative to the Eckumlenkungsgehäuse connected to the second face-plate and the treading member attached thereto. Finally, the first faceplate and the second face plate pivoted relative to each other and thereby engages the locking projection on the first face-plate in the locking receptacle on the second face-plate.

DE 2 224 499 A discloses a drive rod fitting with two cuff rails forming a bracket angle. One of the two cuff rails has a mounting opening. The other faceplate has an angled end on which a rotatably mounted coupling pin protrudes. To connect the two cuff rails of the coupling pin of a cuff rail is inserted through the mounting hole on the other faceplate. Subsequently, the coupling pin is rotated until it overlaps with securing wings the edge of the mounting hole on the other faceplate and thereby secures the previously prepared connector against loosening.

Another 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 bingen with a corresponding hook counterpart at the associated longitudinal end of the other faceplate in engagement. 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.

The present invention has for its object to provide a window or door fitting, the fitting parts can be automated with little effort.

According to the invention this object is achieved in that in the case of a window or door fitting of the type mentioned the characterizing features of claim 1 are provided. The connecting projection is elastically deformable at least in a partial region parallel to the seam peripheral surface and, in the undeformed state, has an oversize relative to the connection receptacle, wherein the connecting projection can be introduced with corresponding elastic deformation into the connection receptacle perpendicular to the seam circumferential surface. By a rectilinear relative movement perpendicular to the fold peripheral surface, the two cuff rails can be connected to one another according to the invention. 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 particular, the compensation of manufacturing and / or assembly tolerances it serves that the connecting projection is mounted floating on the connecting pocket of the first face-plate or on the second face-plate parallel to the Falzumfangsfläche.

An automatic mutual alignment of the connecting projection and connection reception and of the first and second cuff rails 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 receptacle is parallel to the Falzumfangsfläche supportable.

In a preferred embodiment of the invention, the connecting tab 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 area of the second face-plate perpendicular to the Falzumfangsfläche to the window or the door leaf set down. 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.

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 connecting projection in the position of use of the cuff rails on the second faceplate or on the Verblndungslasche the first cuff rails parallel to the Falzumfangsfläche elastically clamped and / or that the connecting projection - when attached to the connecting tab - the second faceplate At the side remote from the connecting tab or, when attached to the second cuff rail, the connecting tab engages positively behind the connecting tab on its side remote from the second cuff rail parallel to the seam peripheral surface.

In the interest of a low production and Cossery effort, the connecting projection is formed in the case of a further preferred embodiment of the invention by at least two spring arms held on the connecting tab of the first face-plate or on the second cuff rail 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, if - as in the invention also realized - the spring arms provided on a cross-sectionally substantially C-shaped base of the spring clip and held by the base of the spring clip on the connecting strap of the first faceplate or on the second faceplate, wherein the base of the spring clip, the connecting strap of the first faceplate or the surrounds second faceplate and project the spring arms 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 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 faceplate spring clip invention is held on the faceplate 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 displaceably 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 an offset to the first cuff rail 1 and offset approximately to the thickness of the overlapping with her area of the second cuff rail 2 perpendicular to the Falzumfangsfläche 4 to the window sash 5 out. The width of the connecting plate 6 is smaller 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 longitudinal direction ( FIG. 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 web 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 compared to this has an excess in both Stulpschienenlängs- and 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 and thus form an elastically deformable in the said direction connecting projection on the connecting plate 6. In the 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 of the free spring arm ends in Stulpschienenquerrichtung exceeds the corresponding dimension of the elongated hole 16 on the faceplate 2. Accordingly, the formed by the spring arms 11, undeformed connecting projection in the direction mentioned an excess over 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 longitudinal direction, one of the transverse walls of the elongated hole 16 located in the cuff rail longitudinal direction runs onto 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 are aligned with their movement in mounting direction 18 in Stulpschienenlängsrichtung automatically against 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.
