Description

The invention relates to a corner bracket of a Stulpschienenanordnung for windows, doors or the like, with two mutually at an angle Stulpschienenschenkeln, which are connected at facing ends via a corner joint, for their preparation at the first Stulpschienenschenkel a form-fitting receptacle for longitudinal support and a form-fitting projection Transverse support and on the second cuff rail legs a positive locking projection for longitudinal support and a positive connection receptacle are provided for transverse support, wherein the positive connection receptacle for longitudinal support on the first cuff rail legs in the main plane parallel Between the longitudinal direction of the first Stulpschienenschenkel between the receiving longitudinal boundaries of the provided on the first Stulpschienenschenkel positive locking receptacle for longitudinal support protrudes and between recording transverse boundaries protruding longitudinally spaced recording longitudinal boundaries between which the positive locking projection for longitudinal support on the second cuff rail engages the form-fitting receptacle for transverse support on the second cuff rail leg, which are spaced from each other on the form-fitting projection to the longitudinal support on the second cuff rail legs in main plane parallel transverse direction of the second cuff rail leg.

Such a corner angle is known from DE 199 21 212 A1 , In the case of the prior art, two cuff rail sections extending at an angle to one another are provided on the mutually facing sides with one connecting end each. About the connection ends results in a mutual longitudinal support and mutual cross support the Stulpschienenabschnitte. The mutual longitudinal support of the Stulpschienenabschnitte is effective parallel to the plane which is spanned by the longitudinal axes of the Stulpschienenabschnitte. The mutual transverse support of the Stulpschienenabschnitte acts in the transverse direction of the plane of the mutual longitudinal support.

The one connection end of the known corner angle has a form-fitting receptacle for longitudinal support and a form-fitting projection for transverse support, the other connection end a form-fitting projection for longitudinal support and a form-fitting receptacle for transverse support. Both connection ends are designed as separate components and riveted to the associated Stulpschienenabschnitt.

To simplify the state of the art in terms of manufacturing technology is the object of the present invention.

According to the invention, this object is achieved by the corner bracket according to claim 1. In the case of the invention, both the positive locking projection for longitudinal support and the positive locking receptacle for transverse support are thus formed directly on the second cuff rail leg. Consequently, the second cuff rail can be made according to the invention corner angle and the associated elements for producing the corner joint of a uniform blank. A connection to be produced in a separate operation between the connecting elements on the one hand and the second cuff rail leg on the other hand is eliminated. The attachment of the hook shape according to the invention on the second cuff rail legs requires only simple production processes.

Particular embodiments of the invention according to claim 1 emerge from the dependent claims 2 to 9.

For the hook shape on the second cuff rail legs different geometries are conceivable. In question comes, for example, a round-arched hook shape. According to the invention, the Eckwinkelbauart is preferred according to claim 2, in the case of which the hook shape is formed on the second Stulpschienenschenkel by two bends and a hook transition region and an end hook end portion which in turn are substantially rectilinear. Such a hook shape can be finished by simple Abkantvorgänge. Are the rectilinear hook transition region and the rectilinear end hook end portion of the hook shape of the second Stulpschienenschenkels assigned to the first Stulpschienenschenkel mating surfaces, which are also rectilinear, so regardless of the low production costs results in a large-scale and thus particularly effective mutual longitudinal support of the two Stulpschienenschenkel. In addition, the positive locking elements on the first cuff rail leg can be produced in a simple manner.

Due to the extension of the provided at the hook end cutout on the hook transition area addition standing on the positive connection for transverse support correspondingly long, formed by the longitudinal edges of the cutout receiving cross-borders to available. These receiving transverse boundaries may be assigned to the first cradle leg store provided form-fitting projection for transverse support over a large area.

Also in the interest of a special effectiveness of the mutual transverse support the characterizing feature of claim 4 is provided. In the case of this invention type, the cutout on the hook shape of the second Stulpschienenschenkels does not open approximately in the free end of the hook shape; Rather, the cutout is limited to the free end of the hook shape through a crosspiece interconnecting the longitudinal edges of the cutout. Characterized a spreading of the opposite longitudinal edges of the cutout is counteracted on the hook shape, as it might occur in opening into the free end of the hook shape neckline when large forces in the transverse direction of the clamped by the longitudinal axes of the two Stulpschienenschenkel on the corner joint between the two Stulpschienenschenkeln Level effect.

The invention features specified in claim 5 effect effective mutual support of the two cuff rail legs both parallel to the plane spanned by the longitudinal axes of the two cuff rail level and in the transverse direction of this plane. Due to the claimed widening of the longitudinal edges or the edges of the cutout on the hook shape of the second Stulpschienenschenkels a large-area contact is possible between the end face of the provided on the second Stulpschienenschenkel positive locking projection for longitudinal support as well as the base of this form-fitting projection opposite the base provided on the first cuff rail positive locking receptacle for longitudinal support. This large-area contact counteracts, inter alia, a mutual twisting of the mutually supported Stulpschienenschenkel.

Another preferred embodiment of the invention uses the one or more longitudinal edges of the cutout on the hook shape of the second Stulpschienenschenkels for producing a latching connection with the first Stulpschienenschenkel (claim 6).

In the interests of the simplest possible manufacture, in the case of the corner angle according to the invention, the broadening and / or the locking element are integrally formed on the relevant longitudinal edge of the cutout on the hook shape of the second cuff rail.

Due to the evidently claim 8 provided in a further embodiment of the invention bend the remote end hook end portion on the second cuff rail that hook end portion cross-recording longitudinal limit of the provided on the first cuff rail form fit receptacle for longitudinal support at its remote from the end remote hook end portion top aligned with the top of the second Stulpschienenschenkels. This results in a substantially offset-free transition between the second Stulpschienenschenkel and said recording longitudinal boundary the form-fitting receptacle on the first cuff rail leg.

A preferred manufacturing technology reasons erfindungsbauart is characterized in that the second cuff rail legs and provided on this hook shape are formed as a uniform punched / bent part (claim 9).

According to the FIGS. 1 and 2 comprises a cuff fitting 1 for mounting to the wing of a window or a door two fitting units 2, 3, which surround a corner of the window or door leaf in the installed position.

The fitting unit 2 comprises a vertical Stulpschienenschenkel 4 (first Stulpschienenschenkel) and guided on its underside in the usual manner drive rod 5. Durch Longitudinal slots 6, 7 of the vertical Stulpschienenschenkels 4 through the drive rod 5 with locking elements 8, 9 is connected. As usual, the locking elements 8, 9 can be moved by actuating the drive rod 5 in the longitudinal direction of the vertical cuff rail leg 4.

At its corner-side end of the vertical Stulpschienenschenkel 4 is riveted to a connecting element 10. The connecting element 10 is of known type and, for example, in FIG DE 199 21 212 A1 described in detail. It serves to produce a corner connection between the vertical cuff rail leg 4 and a horizontal cuff rail leg 11 (second cuff rail leg) of the fitting unit 3.

The horizontal Stulpschienenschenkel 11 carries on its underside in a known manner a drive rod 12. The drive rod 12 is riveted to an eccentric locking pin 13. Upon actuation of the drive rod 12 of the locking pin 13 is moved in the longitudinal direction of the horizontal Stulpschienenschenkels 11. Et al To guide this movement, the horizontal cuff rail leg 11 is provided with a longitudinal slot 14.

Riveted with the horizontal Stulpschienenschenkel 11 is a screw guide piece 15, which passes through the drive rod 12 at a longitudinal slot 16. This allows the longitudinal displacement of the drive rod 12 relative to the screw guide piece 15. A through hole not shown in detail of the screw guide piece 15 is aligned with a mounting hole 17 on the horizontal cuff rail leg 11th

About its corner-side end of the drive rod 12 is connected to a flexible corner 18 of conventional design. The corner drive 18 is guided in a mounted on the horizontal cuff rail 11 C-rail 19. A coupling piece 20 on the C-rail 19 is a coupling opening 21 on the vertical Stulpschienenschenkel 4, a punched-22 on the Eckumlenkung 18 a coupling pin 23 on the drive rod 5 of the fitting 2 assigned.

By means of the hook shape 24 on the horizontal Stulpschienenschenkel 11 and the connecting element 10 on the vertical Stulpschienenschenkel 4, the two Stulpschienenschenkel 4, 11 are joined together to form a corner angle 25. This is the horizontal cuff rail leg 11 and the vertical cuff rail 4 part of a cuff rail assembly 26 of the cuff rail fitting 1 is.

The main plane of the vertical Stulpschienenschenkels 4 is perpendicular to the plane of the FIGS. 1 and 2 and thereby in the direction of a longitudinal axis 27 of the vertical Stulpschienenschenkels 4. At right angles thereto, the main plane of the horizontal Stulpschienenschenkels 11 extends along a longitudinal axis 28 of the horizontal Stulpschienenschenkels 11 and also perpendicular to the plane of the FIGS. 1 and 2 ,

By means of the connecting element 10 on the vertical Stulpschienenschenkel 4 and the hook shape 24 on the horizontal Stulpschienenschenkel 11 between the two Stulpschienenschenkeln 4, 11 made a connection which is effective both parallel to the plane defined by the longitudinal axes 27, 28 plane and in the transverse direction of this plane is.

As in particular the FIGS. 3 and 4 can be taken in detail, the hook mold 24 comprises a horizontal to the cuff rail 11 out, remote hook end portion 29, an end hook end portion 30 and a hook transition region 31, which connects the two hook end portions 29, 30 together. The remote hook end portion 29 is bent transversely to the main plane of the horizontal curb leg 11 to the hook transition region 31 by the dimension d. The hook mold 24 as a whole has a substantially rectangular shape in cross section. An endeferne bending axis 32 and a near-end bending axis 33 extend in the plane parallel to the transverse direction of the horizontal Stulpschienenschenkels 11th

The hook mold 24 forms a form-fitting projection for mutual longitudinal support of the vertical cuff rail leg 4 and the horizontal cuff rail leg 11. In the hook mold 24 incorporated is a form-fitting receptacle 34 for mutual transverse support of the two cuff rail legs 4, 11 (FIG. Fig. 5 ). The positive connection receptacle 34 is formed by a cutout on the hook shape 24 and extends over the entire hook transition region 31 and adjoining subregions of the remote hook end portion 29 and the end hook end portion 30. As recording transverse boundaries 35, 36 of the positive connection 34 serve longitudinal edges of the form-fitting receptacle 34. Towards the free end of the hook shape 24, the form-fit receptacle 34 has a transverse web 37 as a transverse boundary (FIG. Fig. 4 ).

As especially Fig. 5 shows in detail, at the hook transition region 31, the receiving transverse boundaries 35, 36 of the form-fitting receptacle 34 with locking elements in the form of the interior of the form-fitting receptacle 34 projecting locking lugs 38, 39 and on the opposite side with spacers 40, 41 is provided. The longitudinal outer sides of the spacers 40, 41 are aligned with the outer sides of the longitudinal edges of the horizontal Stulpschienenschenkels 11. Both the locking lugs 38, 39 and the spacers 40, 41 are formed laterally on the hook transition region 31 of the hook mold 24.

The unit is made of horizontal Stulpschienenschenkel 11 and hook 24 as a punched / bent part. At a serving as a blank for the entire assembly metal band section is a window-like cutout for the production in the flat state punched out of the form-fitting receptacle 34. The longitudinal edge of the blank is also punched away in the region between the hook-shaped side longitudinal ends of the horizontal curb leg 11 and the spacers 40, 41 as well as in the area between the spacers 40, 41 and the free end of the hook mold 24. The latching noses 38, 39 on the inside the receiving transverse boundaries 35, 36 are created by embossing processing of the relevant workpiece area. Compared with the horizontal Stulpschienenschenkel 11, the hook shape 24 is bent with its end remote hook end portion 29 by the amount d. The rectangular cross-sectional shape of the hook shape 24 is produced by two Abkantvorgänge, one of which is performed by the remote end of the bending axis 32 and the other about the end-near bending axis 33.

The connecting element 10 has a connecting lug 42 for producing the riveted connection with the vertical cuff rail leg 4 (FIG. FIGS. 6 and 7 ). Adjoining the connecting projection 42 to the free end of the connecting element 10 toward a positive connection receptacle 43 for longitudinal support. The positive locking receptacle 43 is open transversely to the main plane of the vertical cuff rail leg 4 and is limited by receiving longitudinal boundaries 44, 45 and by a receiving base 46. The receiving longitudinal boundaries 44, 45 and the receiving base 46 of the positive locking receptacle 43 have a U-shape in cross section. The thickness d of the end-side longitudinal recording limit 45 corresponds to the dimension d of the bend of the end remote hook end portion 29 of the hook mold 24th

Between the receiving longitudinal boundaries 44, 45 of the positive locking receptacle 43 extends a positive locking projection 47 for transverse support. This is formed on the receiving base 46. A locking element in the form of a spring clip 48 is pushed onto the form-fitting projection 47 and engages behind it with the free ends of clip legs 49, 50. Due to a corresponding dimensioning of the clip legs 49, 50 remain between them and the receiving base 46 of the form-locking receptacle 43 latching intermediate spaces 51, 52nd

When mounting the Stulpschienenbeschlages 1, the fitting unit 3 is used in a conventional manner in a fitting part, which extends to the respective window or door leaf in Falzumfangsrichtung. A provisional fixing of the fitting unit 3 is effected by means of the screw guide piece 15, which acts on the opposite longitudinal walls of the fitting part groove with clamping elements not described in detail. The horizontal Stulpschienenschenkel 11 covers the horizontal part of the fitting part. The vertical leg of the C-rail 19 connected to the horizontal cuff rail 11 and the relevant part of the corner drive 18 and the associated add-on parts 20, 22 come to rest in the vertical part of the fitting part groove.

In one in the FIGS. 2 and 8th In the next assembly step, the fitting unit 2 is inserted into the vertical part of the fitting part groove by the mounting direction illustrated by an arrow 53. In this case, the fitting unit 2 is aligned relative to the preassembled fitting unit 3 such that the hook shape 24 comes to rest on the horizontal Stulpschienenschenkel 11 at the end of the assembly movement in the interior of the form-fitting receptacle 43 of the connecting element 10 on the vertical cuff rail leg 4.

During the assembly movement, first the clip legs 49, 50 of the spring clip 48 run on the connecting element 10 on the latching lugs 38, 39, which are beveled towards the connecting element 10, on the hook shape 24. If the assembly movement is continued, then push the locking lugs 38, 39, the clip legs 49, 50 against the interlocking projection 47 before they lock after passing the clip legs 49, 50 and reaching the locking gaps 51, 52 behind the clip legs 49, 50. To release the latching connection, the clip legs 49, 50 are to be pushed back against the form-fitting projection 47 by means of a suitable tool.

At the finished corner angle 25, the form-fitting projection 47 on the connecting element 10 is now inside the form-locking receptacle 34 on the hook shape 24. The widenings 40, 41 of the hook transition region 31 of the hook shape 24 are based on the receiving base 46 of the connecting element 10.

At the same time, the receiving longitudinal limiters 44, 45 of the positive locking receptacle 43 on the connecting element 10 extend over or under reach the faraway hook end section 29 and the end hook end section 30 of the hook mold 24. The upper side of the receiving longitudinal boundary 45 is flush with the upper side of the horizontal Stulpschienenschenkels 11.

All in all, results between the vertical cuff rail legs 4 and the horizontal cuff rail leg 11 and thus between the fitting unit 2 and the fitting unit 3, a connection which is both parallel to the plane defined by the longitudinal axes 27, 28 of the cuff rail legs 4, 11 plane and in the Transverse direction is effective.

With the connection between the vertical Stulpschienenschenkel 4 and the horizontal Stulpschienenschenkel 11 also a connection between the drive rod 5 of the fitting unit 2 and the drive rod 12 of the fitting unit 3 is made. Specifically, the coupling pin 23 immersed on the drive rod 5 in the punched-22 of the corner drive 18 connected to the drive rod 12. A positive connection between the fitting components which are stationary when the cuff rail fitting 1 is actuated is produced via the coupling piece 20 on the C rail 19 of the fitting unit 2, which engages in the coupling opening 21 on the vertical cuff rail leg 4 of the fitting unit 2 in the assembled state. For final fixation of the faceplate fitting 1 to the relevant window or Door leaves are screwed to the screw guide piece 15 of the fitting unit 3 and other, not shown in detail mounting points of the fitting units 2, 3 fastening screws in the material of the window or door sash.
