Description

The present invention relates to a corner drive for an espagnolette fitting system for a window or door wing, comprising an angle-shaped corner curb rail with two cuff rail legs, wherein at the free end portion of at least one, preferably both, cuff rail legs preferably provided by an offset to the cuff rail leg end portion is provided a along the Eckstulpschiene extending guide channel with a flexible coupling element displaceable therein, which is connected in his in the region of the cuff rail extending and verschiebaren in the guide channel sections each with a beyond the free end of an associated Stulpschienenschenkels out extending connecting rod portion, and at the free End portion of at least one of the Stulpschienenschenkel a in the longitudinal direction of the Stulpschienenschenkels with the staggered leg end portion overlapping and a guide opening in a drive rod section passing through, fixed to the cuff rail leg guide element.

Such Eckumlenkung is from the DE 198 34 038 C2 known. In order to obtain in a mounting phase, so when attaching a corner on the frame of a window or door leaf in a designated fitting groove, a prefixing and thus keep the corner drive in pre-fixed state on the frame until more fitting system components are provided and then possibly are set together with the corner steering on the frame, a substantially U-shaped clamping spring element is provided in this known corner deflection. This is where the guide channel in adaptation to the corner of the corner turret rail arcuately curved, pushed from the inside, so from the bottom of the fitting groove side facing on the guide channel. With its two webs this clamping spring element engages around the guide channel. The free end portions of these webs are outwardly, ie laterally bent with respect to a longitudinal direction of the guide channel, so that they get into the fitting groove on the two Nutseitenwandungen when inserting the Eckumlenkung and fix the corner deflection under bias. Since this clamping spring element is pushed onto the guide channel, it can only be arranged where a disturbing interaction with the drive rod sections, which are connected to the displaceable in the guide channel flexible coupling element, is avoided. This limits the area of attachment of such a clamping spring element substantially to the curvature region of the guide channel.

The DE 196 46 988 C2 discloses a fitting for a window, in which also the possibility of pre-fixing of the fitting is given by a clamping spring element. In the embodiment of the fitting as corner deflection, this clamping spring element is arranged in an approximately triangular space formed between the curvature region of the guide channel for the flexible coupling element and the corner region of the Eckstulpschiene. On the likewise substantially triangular clamping spring element are laterally flexible protrusions protruding, which produce a Klemmfixierwechselwirkung with the Nutseitenwandungen provided in a sash fitting groove. Furthermore, this document discloses the configuration of a guide rod passing through a guide element with laterally projecting Klemmfixierfederabschnitten, which can also produce a clamping action, namely the fact that they either rest against Nutseitenwandungen or engage under projections provided. This known guide element is further configured such that it engages behind openings provided with latching sections in a region passing through a guide opening in the drive rod section in a cuff rail. The purpose provided and the faceplate engaging behind sections are visible from the outside and are not covered by other components in attached to a casement fitting.

The DE 297 16 501 U1 discloses a fitting with a faceplate on which a substantially U-shaped clamping spring element is provided. The clamping spring element has on its U-legs in the region in which they lie in a fitting groove, laterally bent Klemmfixierfederabschnitte, which cooperate with the Nutseitenwandungen to produce a fixing effect. At the free end portions of the U-legs, these are bent adapted to the cross-sectional contour of a faceplate, so that they overlap the outer face of the faceplate and their outwardly exposed side. This clamping spring element thus lies with its cuff rail engaging portions between the faceplate and the sash. This leads to the disadvantage that the faceplate no longer rests flat on the casement, but is supported only at this, where such a clamping spring element is provided. Also, the cuff rail on its outside cross-sections of this clamping spring element are visible to the outside and not covered by other components.

It is the object of the present invention to design a generic corner drive such that, without affecting the visual appearance and the mounting state of the corner steering on a wing, a stable fixing effect for the corner deflection can be generated in this fitting fitting groove.

According to the present invention, this object is achieved by a corner drive for a drive rod fitting system for a window or Door leaf, comprising an angle formed Eckstulpschiene with two Stulpschienenschenkeln., Wherein at the free end of at least one, preferably both, Stulpschienenschenkel preferably offset by bending to Stulpschienenschenkel leg end portion is provided, along the Eckstulpschiene extending guide channel with a flexible coupling element displaceable therein , which is connected in its in the region of the cuff rail legs extending and verschiebaren in the guide channel sections each with a beyond the free end portion of an associated cuff rail out end extending drive rod section, and at the free end of at least one of the cuff rail legs in the longitudinal direction of the cuff rail leg itself with the staggered leg end portion overlapping and a guide opening in an espagnolette section passing through, on the Stulpschienensche nkel fixed guide element.

According to the invention it is further provided that a clamping spring element is held at least one of the leg end portions between this and the guide element, which at least one laterally with respect to the longitudinal direction of the cuff rail leg over the leg end portion protruding Klemmfixierfederabschnitt Klemmfixieranlage on a groove wall of a Eckumlenkung receiving fitting groove in a wing having.

In the Eckumlenkung invention, it is thus possible to position such a clamping spring element in a range where it can produce a stable clamping effect on the one hand, especially if in the areas of both Stulpschienenschenkeln such clamping spring elements are provided, and where, on the other hand, then when the Eckumlenkung prefixed or fully assembled to a wing, the presence of such a clamping spring element from the outside is not recognizable. Also, the clamping spring element does not affect the support of the faceplate of Corner guide on the wing in the groove provided.

A stable embodiment of the clamping spring element can be obtained in a simple manner, if this comprises a substantially planar body portion, which bears against the side facing the guide element of the leg end portion.

In order to ensure in a pre-assembly state that the clamping spring element is stably held on the Eckumlenkung, it is proposed that on both sides of the body portion Klemmhaltefederabschnitte are provided which hold a leg end portion between them holding the clamping spring element at the leg end portion.

If it is further provided that is provided in association with at least one of the Klemmhaltefederabschnitte in the leg end portion a receiving this and with this in the longitudinal direction of the cuff rail limb forming a form-fitting retaining Klemmhalteaussparung, it is ensured that during the assembly process, so when inserting a corner drive in a Fitting groove on a wing unwanted displacement of such a clamping spring element can not occur. In order to be able to provide a clamping spring element even after the assembly of the other components of the corner deflection in a Eckumlenkung invention, it is further proposed that the body portion is not clamped between the leg end portion and the guide member.

The clamping effect can be further improved in that the clamping spring element has on both sides in each case at least one Klemmfixierfederabschnitt. It can be provided, for example, that at least one Klemmfixierfederabschnitt is provided on each side of the body portion in the longitudinal direction on both sides of a respective Klemmhaltefederabschnitts.

The at least one Ktemmfixierfederabschnitt may be bent about an axis substantially parallel to the longitudinal axis of the Stulpschienenschenkels axis with respect to the body portion in the direction away from the guide element. Thus, regardless of the direction in which a clamping spring element is inserted into a fitting groove, so either transversely to the fitting groove longitudinal direction or in this direction, this always develop its optimal clamping fixation.

The at least one staggered end portion may be offset by an offset corresponding at least to the thickness of the cuff rail leg. This makes it possible to provide a further assembly of a fitting system, which is formed with an identically dimensioned face-plate following such Eckumlenkung.

In order to achieve a stable locking of a Eckumlenkung invention on a sash, for example, if all components of a fitting system are provided on this frame, it is further proposed that in the staggered leg end portion, the clamping spring element and the guide element mutually aligned through openings are provided for a fastening member ,

The Fig. 1 and 2 These comprise a Eckstulpschiene 12 with two Stulpschienenschenkeln 14, 16. In a corner region 18, the two Stulpschienenschenkel 14, 16 of the z. B. generated by bending a sheet metal strip Eckstulpschiene 12 to each other. In their two free end regions 20, 22, the stucco rail legs 14, 16 are bent twice, resulting in leg end sections 24, 26 that are offset relative to the other sections of the cuff rail legs 14, 16, namely by an offset that is essentially the same Thickness of the cuff rail legs 14, 16 corresponds. One recognizes especially in Fig. 2 in that the leg end sections 24, 26 in the lateral direction, ie transversely with respect to a longitudinal direction L of the cuff rail legs 14, 16, are somewhat narrower than the cuff rail legs 14, 16 in their other areas.

Facing one of a fitting groove to postionierenden inside 28 of the Eckstulpschiene 12 is a generally formed with a C-shaped cross-section, for example, bent sheet metal guide channel 30 is provided. This guide channel 30 is formed in the corner region 18 of the Eckstulpschiene 12 with an arc portion 32 and extends along the Stulpschienenschenkel 14, 16 close to the offset leg end portions 24, 26 zoom. The open side of the C-shape of the guide channel 30 is provided on the side facing away from the Eckstulpschiene 12 side, and in the guide channel 30 is a flexible Coupling member 34 slidably received in the longitudinal direction of the guide channel 30. This flexible coupling element 34 may for example be constructed of a plurality of layers of thin spring steel layered and has an overall length which is shorter than the total length of the guide channel 30. At several positions, the guide channel 30, for example, by riveting or by spot welding to the Eckstulpschiene 12th be set.

In those areas in which the flexible coupling element 34 is displaceable in the guide channel 30 along the cuff rail legs 14, 16, the coupling element 34 is fixedly connected to drive rod sections 36, 38, for example by riveting. The drive rod sections 36, 38 thus lie on the inner side 28 of the Eckstulpschiene 12 and also of the guide channel 30 and extend beyond the free end portions 20, 22 of the cuff rail legs 14, 16 also. The drive rod sections 36, 38 can, as in the Fig. 2 is clearly visible, be formed with toothed portions 40 in order to obtain a coupling complementary shaped rack portions of adjacent drive rod sections.

In the end regions 42, 44, in which the drive rod sections 36, 38 are coupled to the flexible coupling element 34, they can furthermore carry a respective slot-like opening 46 in the guide channel 30 or 48 in the associated cuff rail 16 passing through locking bolts, which thus on the outside 50 of the corner cuff rail 12 also extend and can cooperate with provided on a fixed frame Schließorgangen.

In the area of the free end regions 20, 22, guide elements 52, 54 are arranged on the corner cuff rail 12. These pass through a slot-like opening 56 in a respectively associated with the drive rod sections 36, 38 and extend with a mounting portion 58 through a Opening 60 in the associated end region of the guide channel 30 and an opening 62 at the associated free end portion of a respective Stulpschienenschenkels 14, 16 therethrough. By caulking or flattening, the mounting portion 58 of the generally made of metal material guide members 52 and 54 are then deformed in the opening 62 so that a stable holding action is generated through which simultaneously the end portions of the guide channel 30 on the cuff rail legs 14 and 16 are set. Immediately adjacent to the opening 62 in Stulpschienenschenkel 16, a screw 64 is provided through which passes through a slot-like opening 46 in the guide channel 30 and 56 in the drive rod section 36 and 38 and guided through a corresponding opening 66 in the respective guide element 52 or 54 Fixing screw can be screwed into a sash. It should be emphasized here that, in principle, the structure at both free end regions 20, 22 of the corner turret rail 12 or the cuff rail legs 14, 16 can be the same.

In adaptation to the offset end portions 24, 26 of the cuff rail legs 14, 16, the guide elements 52, 54 on a recessed portion 68 which is opposite to the respective end portion 24 and 26 at a distance or overlaps with this. In the respective end portion 24 and 26 and in the guide element further openings 70, 72 are provided, through which a further fastening screw can be screwed into the casement. In addition, a respective end section 24 or 26 overlapping end region of an adjacent faceplate can be fixed with this fastening screw.

In the corner guide 10 constructed according to the invention, a clamping spring element 74, 76 is arranged between at least one, preferably both end sections 24, 26 offset towards the inside 28 and the recessed area 68 of the respectively associated guide element 52, 54 intended. This in Fig. 3 enlarged illustrated clamping spring element, in Fig. 3 If the clamping spring element 74 constructed identically to the clamping spring element 76 is shown, it is constructed, for example, from thin spring steel sheet and has a substantially planar body section 78. This lies between the respective end portion 24, 26 and the opposite guide member 52, 54. However, the recessed portion 68 while the clamping spring element 74 and 76 is not clamped between the end portion 24, 26 and the associated guide member 52, 54. At its two relative to the longitudinal direction L lateral ends 80, 82 adjoin the body portion 78 a plurality of this angled protruding Klemmfixierfederabschnitte 84 at. These are bent, for example, by bending about a bending axis B substantially parallel to the longitudinal axis L on the blank formed, for example, by punching out with respect to the body portion 78, preferably in an angular range between 90 and 130 ° with respect to the planar body portion 78.

Next you can see in Fig. 3 in that, approximately in the center, centered on the longitudinal direction L, between each two pairs of clamping-fixing spring sections 84 is a clamping-retaining spring section 86, 88. Again, these are formed by bending relative to the planar body portion 78 and shaped to extend toward each other with respective abutment areas 90, 92.

The Fig. 4 shows on the basis of the end section 26 that the end sections 24, 26 have recesses 94, 96 at their two lateral regions. In this grip in the assembled state, the clamping retaining spring portions 86, 88 a. The Klemmhaltefederabschnitte 86, 88 are dimensioned and shaped so that they rest under bias on the side surfaces of the respective end portion 24 and 26, so clamp between them and thereby by Klemmhaltewirkung the clamping spring element 74 and 76 at the respective end portion 24 and 26 respectively fix. The extension of the Klemmhaltefederabschnitte 86, 88 in the longitudinal direction L is preferably only slightly shorter than the corresponding extension length of the recesses 94, 96, so that not only a Klemmhaltewirkung is achieved, but in particular in the longitudinal direction L a positive holding interaction between the Klemmhaltefederabschnitten 86, 88 and the Recesses 94, 96 and the respective end portions 24, 26 is generated.

If such a Eckumlenkung 10 configured with the clamping spring elements 74, 76 on a casement, for example, a window sash or door leaf, arranged in a formed therein and outwardly open fitting groove, the results in the Fig. 5 illustrated by the cuff rail leg 16 situation. It should be noted that in the Fig. 5 the normally provided on this cuff rail 16 guide member 54 and the associated drive rod portion 38 are not shown. One recognizes a region of a casement 100 with a fitting groove 102 formed therein, which is relevant for the presentation of the present invention. This casement 100 can be produced, for example, from plastic material by extrusion, but can of course also be a wood frame machined by milling. The fitting groove 102 is stepped, so that the Eckstulpschiene 12 and its Stulpschienenschenkel 14, 16 rest on respective stepped surfaces 104, 106 of the side walls 108, 110 of the fitting groove 102. Between the two surfaces 104, 106 are the slightly narrower sized end portions 24, 26, in such a way that their surface lying to the outside in the assembled state approximately flush with the surfaces 104, 106 connects. The clamping spring elements 74, 76 which are below the respective end portion 24 and 26 and are held on this, based with their Klemmfixierabschnitten 84 by the Aufspreizwirkung on the Nutseitenwandungen 108, 110 here in the area of the surfaces 104, 106 providing, after inside cross-projections 112, 114 from. By this Aufspreizwirkung and by the Fact that the Klemmfixierfederabschnitte 84 to the outside, ie in the direction of the in Fig. 5 unrecognizable guide element are bent, they can be easily inserted into the fitting groove 102, but produce in the attempt to remove such a prefixed corner 10 again from the fitting groove 102, an expansion that does not allow an unwanted falling out of the corner.

Since a plurality of such Klemmfixierfederabschnitte 84 is provided in the present invention provided Klemmfederelemeten 74 and 76 at each lateral end portion 80 and 82, a very stable Klemmfixierwirkung achieved. This can be further enhanced by the fact that the clamping retaining spring sections 86 are curved laterally outwards in their end sections beyond the contact areas 90, 92, so that with these end sections the clamping retaining spring sections 86, 88 also provide Klemmfixierfederabschnitte 84 ', on the one hand against the side walls 108, 110 of the fitting groove 102 create, on the other hand but on the contact areas 90, 92 are supported on the side edges of the end portions 24, 26.

By the present invention, a corner deflection is provided, in which by simple measures the prefixing of the same can be obtained in a fitting groove. In this case, the pre-fixing takes place in such a way that a mutual impairment with movable components, in particular the drive rod sections, can not occur. In particular, the prefixing takes place directly in the end regions of the corner deflection, so that it can be fixed very stably at two points that are comparatively far apart from each other. The components used for fixing, so the clamping spring elements are not visible to the outside used in a fitting groove corner deflection, so do not affect the appearance of a provided on a wing fitting system.

Due to the fact that the clamping spring elements are not between the End portions and the associated guide elements are clamped, so between them a gap is created, which is slightly larger than the material thickness of the clamping spring elements in the region of their body portion, it is also possible, these clamping spring elements only after the complete assembly of a corner by pushing in the longitudinal direction to set to a respective end portion of it. For this purpose, only the two clamping retaining spring sections need to be spread laterally. It can be retrofitted already produced corner deflections, if necessary. In particular, in systems in which fastening screws are to be introduced through the end sections or the openings 70 provided therein, it is further advantageous if in the body section 78 the clamping spring elements 74 each have an opening 116 which allows the passage of such a screw.

It should be pointed out that, of course, various variations can be made to a corner drive constructed according to the invention, in particular to the components serving for clamping fixation, without deviating from the principle of the invention. For example, the clamping spring elements can not be made of spring steel, but for example as plastic cast elements. Of course, the number of Klemmfixierfederabschnitte or even the Klemmhaltefederabschnitte can be varied. In particular, the clamping retaining spring sections may be shaped differently, for example, lie at the four corner regions of a clamping spring element. The contact areas 90, 92 may be formed with more or less sharp-edged contour, in order to achieve a stable support not only by frictional engagement, but also by a positive connection produced by slight cutting. It is of course also possible to provide such a clamping spring element at such a corner deflection only at one of the end regions of the cuff rail legs. It should also be noted that of course other hardware assemblies can be configured with such a clamping spring elements, provided that the Stulpschienenabschnitte of the same, for example, formed by bending and offset end portions have. In any case, by very simple and easily variable measures, such as the variation of the length of the Klemmfixierfederabschnitte or their angle of attack, an adaptation to different sized fitting grooves can be achieved.
