EP1437471B1 - Fitting for a lifting and sliding door or a lifting and sliding window - Google Patents

Description

The invention relates to a fitting for lift-slide doors or windows according to the preamble of claim 1 and to a lift-slide door or a lift-slide window according to the preamble of claim 15.

Lifting and sliding doors or lifting and sliding windows as well as suitable fittings for these doors are known. The basic function of such doors or windows is that the respective door or window sash is raised and lowered relative to an outer floor frame and at the same time is displaceable in the wing plane, so that, for example, to open the closed wing this first raised in the vertical direction and then is shifted in the horizontal direction. In the reverse manner, the closing of the wing. As a further function in particular lifting and sliding doors can also have a tilt function.

It is also known to provide a manually operable transmission for raising and lowering a vertical sash frame element forming the opening or closing side of the sash ( DE 78 16 563 U1 ), which is connected in particular for raising and lowering via a drive rod fitting or, via a provided on a faceplate drive rod and a corner drive drivingly provided with on the underside of the wing carriage or running shoes. When manual actuation of the transmission, the drive rod is moved, thereby moving the carriage or running shoe of the fitting relative to a provided on the lower horizontal spar of the sash frame bearing element in the longitudinal direction of the running. About an obliquely placed slot-pin guide between the running shoe and the bearing element in this case a change in distance between the running shoe and the lower horizontal spar of the wing and thus the raising and lowering of the door relative to the outer floor or frame done. The first generated during movement of the hand lever on the lifting gear vertical movement must be from a provided on a vertical side of the sash frame drive or push rod in a horizontal Movement be implemented. In the known fitting, this is done by a two-armed lever, which is also referred to as a bell crank and which is pivotally mounted about an axis perpendicular to the plane of the wing, on a bearing element of the fitting, which in the fold of the wing at the corner between the vertical and the lower horizontal rail or section of the sash.

To attach the faceplate with its drive rod and to accommodate the corner and the carriage, but also to accommodate other management and fitting elements grooves (Einhaunuten) are provided on the periphery or in the fold of the sash, but which are formed differently on the individual sash elements.

Another disadvantage of this known fitting is that the deflector formed by the two-armed lever requires a relatively large installation space in the wing, which must be created by a correspondingly large depth of the groove in the rebate (Einbaunut). This deep milling means i.a. a weakening of the wing and thus at least counteracts the requirement of the highest possible security against burglary.

The different design of the grooves on the wing frame elements requires the use of different milling tools or a corresponding tool change in wooden sash, while plastic sash for the production of sash profiles different extrusion tools are necessary, which increases the manufacturing cost and manufacturing costs.

Furthermore, U-shaped cuff rails are generally used in lifting-sliding doors or windows so far, which lead the respective drive rod slidably between their legs and are supported by the free edges of their legs at the bottom of the groove. The disadvantage here is that such U-shaped cuff rails are bulky, heavy and expensive and also require in the rebate a groove (Einbaunut) with a relatively large width, and that conditionally on the one hand by the additional material thickness of the legs and in particular also due to the fact that when using the manually operable transmission, the U-shaped face-plate has to overlap the housing of this transmission.

Fittings are also known in which the corner drive consists of several lamellar spring steel strips arranged one above the other ( DE 34 40 505 ) or is formed by a chain ( DE 72 44 800 ). These embodiments have the disadvantage that the transmission of shear or compressive forces is insufficient and therefore the lowering of the door leaf must be supported by the weight of this wing at least for this reason. The latter affects, inter alia, the free design possibility of acting between the running shoe and the associated bearing element lifting curve.

It is also known in Hebe sliding fittings to make the carriage or running shoe housing in several parts, with two side plates, wipe which the rollers of the running shoe are rotatably mounted. This training also means a relatively large effort in the production.

Also known is an espagnolette fitting for windows or doors ( EP 0 493 689 A1 ) with an attachable in the region of a corner of a wing on a wing-side groove corner drive and with subsequent attached in the region of the wing-side groove Stulpschienenstücken, on each of which a part of a drive rod is slidably guided. A provided with mounted fitting on an upper, horizontal spar of the sash and flat trained Stulpschienenstück is mounted on the wing-side groove so that this Stulpschienenstück with edge portions which protrude laterally beyond the one Verschlußzapfen supporting rod, is received in recesses on the opening edge of the wing-side groove and abuts against contact surfaces formed there.

The object of the invention is to show a fitting (espagnolette fitting), which can be made particularly inexpensive in a reliable operation and also allows a reduction in the width and / or depth of the installation groove.

To solve this problem, a fitting according to the patent claim 1 is formed. A lift-slide door or a lift-and-slide window is designed according to claim 15.

In the invention, the faceplate of a fitting for lifting-sliding doors or windows is flat or flat-band-like design.

In one embodiment of the invention, the Eckumlenkung is formed by a rigid, rod-like or pressure and Zugstückartigen coupling piece, which is guided displaceably in the bearing element. A bell-like, two-armed lever and the associated disadvantages, in particular an additional manufacturing effort and a relatively large space requirement during installation, are thus avoided. By rod-like or pressure and Zugstückartige training of the clutch gap this is able to transmit both tensile forces and compressive forces reliably on the running shoe.

The FIG. 1 shows a building door, which consists in a conventional manner from the floor or window frame 1 and from the door provided in this frame 2, which formed as a lift-slide-wings, for example, with additional tilting function is, that can be raised or lowered for opening and closing in the vertical direction and is displaceable and tiltable.

On the wing 2 or on the sash of the lifting and sliding fitting is provided in a known manner, which is generally denoted by 3 in the figures and, inter alia, attached to a vertical fold of the sash 2.1 faceplate 4, which there with a not shown Handle operable lifting gear 5 and on the face plate 4 axially displaceable (double arrow V) and driven by the transmission 5 drive rod 6 has. That in the Figures 2 . 3 and 4 lower end of the faceplate 4 is connected to a leg 7.1 of an angular bearing element 7, which is made of a suitable material, for example of plastic or metal.

The bearing element 7 is connected to the leg 7.1, which is oriented in the mounted state of the fitting 3 in the vertical direction, with the face plate 4, for example by screws or rivets. Another leg 7.2 of the bearing element 7, which is provided with mounted fitting 3 on the lower horizontal rail of the door leaf frame 2.1, forms the bearing for the housing 8 of a running shoe. 9

The housing 8 is in the illustrated embodiment in one piece of a suitable material, for example of metal, e.g. manufactured as a metal injection molding (zinc injection molded part), with two extending in the longitudinal direction of the running shoe 2 parallel housing walls 10, which are connected to each other at the two ends of the housing by corresponding walls 11. Between the two ends, the walls 10 are still connected by additional stiffening walls 11.1.

In the housing 8, two rollers 12 are freely rotatably supported in the dargstellten embodiment, namely about axes perpendicular to the plane of the door leaf 2. The rollers 12 are in a known manner with a at the bottom of the element Stock frame 1 provided rail 13 in engagement, which is also made of metal, for example.

For raising and lowering the door leaf 2, an oblique lifting cam is provided on the leg 7.2, in the form of an oblique, slot-like opening 14, which encloses an acute angle with the longitudinal extent of the leg 7.2. The opening 14 is provided on a projection 15 which is received between the walls 10, projects from the Türfl ügel adjacent side of the leg 7.2 in the housing 8 of the running shoe and lateral guide surfaces for the inner surfaces of the longitudinal walls 10 forms. By the recorded between the two walls 10 projection 15 of the running shoe 9 is guided clearly on the bearing element 7. In the opening 14 engages these walls 10 connecting guide pin 16 a.

By axial displacement (double arrow H) of the running shoe 8 relative to the bearing element 7, the raising and lowering of the door leaf 2. This displacement takes place via the drive rod 6 by manually operating the transmission 5. For the driving connection between the drive rod 6 and the running shoe. 9 a coupling piece 17 is provided which is rigidly designed as a pressure and Zugstück and formed in the illustrated embodiment as part of a ring. For the coupling piece 17 is formed in the bearing element 7 in the region of the corner between the legs 7.1 and 7.2 of wall sections 18 and 19, a circular arc-shaped guide, in such a way that the coupling piece 17 in this guide on a circular arc about an axis perpendicular to the plane of the door leaf is movable (double arrow K).

At one end, the coupling piece 17 is provided on its outer, ie convexly curved side with a plurality of teeth 20 forming a toothing. This gearing engages in openings 6.1 at the lower end of the drive rod 6, so that the axial movement of the drive rod 6 (double arrow V) the coupling piece 17th corresponding to the double arrow K performs a longitudinal movement in the form of a circular motion.

The teeth 20 remote from the end of the coupling piece 17 is pivotally connected to the coupling piece adjacent this end of the running shoe 6, and in fact that the relevant end engages with a hook-like portion 21 in an opening 22.1 provided on the end wall 11 Ösenabschnitts 22. As in particular the FIG. 4 shows, the coupling piece 17 engages with its portion 21 from above into the recess 22.1 of the eyelet portion 22 and engages behind an edge of the eyelet portion 22 with a rounded surface 21.1 formed on the portion 21. The training is further made such that the section 21 is guided at two in an axial direction perpendicular to the wing plane or parallel to the axis of rotation of the rollers 12 staggered side surfaces of surfaces within the recess 22.1, whereby the movements of the coupling piece 17 and the running shoe. 9 are stabilized when raising and lowering the door leaf 2.

How the particular FIG. 4 Furthermore, shows the axis of the circular arc movement of the coupling piece 17 is within the angular space formed by the legs 7.1 and 7.2, and perpendicular to a plane which is defined by the longitudinal axes of these legs.

With the coupling piece 17 of the illustrated fitting 3 avoids the usual in lifting and sliding fittings pivotable deflection bell. This results in a very simple and reliable construction. Due to the formation of the coupling piece 17 at the one end as a circular arc-shaped toothed rack reliable drive connection between the drive rod 6 and the coupling piece 17 and the running shoe 9 is ensured, namely a driving connection through which both tensile forces for lifting the door, as Also shear forces for lowering the door leaf 2 can be effectively transferred. Another advantage of the deflection using the coupling piece 17 is that the bearing element 7 can be formed very small volume in the region of this deflection, which is therefore kept small for the installation in the door 2 required space.

Like in the FIG. 1 is shown at the lower, horizontal portion of the sash 2.1 on another bearing element 23, a further running shoe 24 is provided, in the region of the bearing element 7 remote second lower corner of the sash 2.1. The bearing element 23 is similar to the leg 7.2 of the bearing element 7 is formed. The running shoe 24 corresponds to the running shoe 9. Both running shoe 9 and 24 are connected in a known manner via a connecting member 25 with each other, which is suitable for the transmission of compressive and tensile forces. This connecting member 25 is, for example, a connecting rod, which is fastened at its ends to the running shoes 9 and 24, by engaging in sleeve-like coupling or connecting portions 26, the front of the respective shoe housing 8 and 8a, ie in the region of the end wall 11th are formed.

The running shoe housing 8a of the running shoe 24 differs from the running shoe housing 8 only in that a coupling section 26 is located on both end walls 11 of the running shoe housing 8a.

The FIG. 7 shows the installation state of the bearing element 7 and the leg 7.2. This is taken up together with the running shoe 9 in a groove 27 provided on the underside of the door leaf. On both sides of the groove two extending over the entire width of this door leaf seals 28 are provided on the underside of the door, which bear against a sealing surface 13.1 of the track rail 13 when lowered, ie closed door 2.

The FIG. 8 shows in cross-section a connection 25 or connecting rod 25.1 with a circular cross-section and a connecting rod 25.2 with a square cross section, which can be used optionally as a compound 25. The cross sections of the two connecting rods are coordinated so that the diagnosis of the cross section of the square connecting rod 25.2 is slightly larger than the Druchmesser or twice the radius of the cross section of the connecting rod 25.1.

In order to be able to use both connecting rods 25.1 and 25.2 optionally, the coupling section 26 integrally formed on the respective end of the running shoe housing 8 or 8a has an opening 29 whose cross-sectional shape initially corresponds to a square cross section, combined with a circular cross section in such a way that in that each of the four sides of the cross section has a circular cylindrical curved portion 30 corresponding to the circular cross section, and those portions 30 curved about the common center axis of the sleeve opening 29 are formed so as to obtain the corner portions 31 of the square cross section, ie there are perpendicular to adjacent surfaces. This means that the radius of curvature of the curved regions 30 is again smaller than half the distance between two diagonally opposite corner regions 31.

To connect two running shoes, for example, the running shoes 9 and 24, the respective connecting rod 25.1 or 25.2 is inserted with one end into the opening 29 of a sleeve-like coupling portion 26 on the running shoe housing 8 and 8a and then provided with this coupling portion 26 locking means, for example Clamping screws 32 clamped.

For the connecting rods 25.1 and 25.2 can be used on the market inexpensively available rod profiles made of metal, for example steel. The total cross section of these connecting rods can be kept relatively small, since in the case of use, the respective connection 25 or connecting rod 25.1 or 25.2 is essentially claimed only to train. This results from the formation of the lifting curves 16 on the bearing elements 7 and 23, respectively. The longitudinal extent of the respective lifting curve closes with the horizontal (axial direction of the double arrow H). an acute angle α, ie an angle α less than 90 ° ( Fig. 4 ), which opens in the running shoe 9 to the corner 7 and in the running shoe 24 from the running shoe 9 out. This course of the lift curve results in the tensile load in the connection 25 due to the weight of the door leaf 3. Compressive forces do not occur in this connection.

In the Figures 10-16 is designated 101 building door, which in turn has an outer floor or frame 102, provided in this frame fixed space 103 with the associated frame 104 and the associated glazing 105 and a wing 106 which is formed as a lifting and sliding wings.

The wing 106, in turn, consists of the wing frame 107, which has the glazing 108 and is composed of four wing frame elements, which adjoin one another at right angles, from a sash profile, e.g. is made of wood, namely from the lower horizontal sash member 107.1, the opening or transmission side of the wing 106 forming vertical sash member 107.2, the upper horizontal sash member 107.3 and the other vertical sash member 107.4.

In the sash member 107.2 the hand lever 109 having a gear 110 is provided, with which a provided in the fold of the sash frame 107 espagnolette u.a. a locking or unlocking of the wing 106 moved to the closed position is also possible on the frame 102 as well as the raising and lowering of the wing 106 for opening or closing.

To open the door 101, the wing 106 can be moved in the raised state parallel to its wing plane or parallel to the plane of the fixed field 103 in the horizontal direction. For this purpose, two running shoes or carriages 111 are provided in the illustrated embodiment at the lower horizontal sash member 107.1, which in the FIG. 10 only with their carriage rollers 112 schematically are indicated and which are guided with these rollers 112 in a horizontal guide rail. For raising and lowering the wing 106, the two carriages 111 are formed with corresponding actuatable via the espagnolette lifting means.

The FIG. 11 shows a simplified representation of the lower, horizontal sash element 107.1 in a sash frame 107 made of wood. In this wing frame element, inter alia, at the bottom of a groove 113 is introduced, which is open to the bottom of the sash member 107.1 out and lies in the illustrated embodiment with its center plane in the vertical center plane of the sash member 107.1. The groove 113 serves to receive the carriages 111, which are provided offset in this groove in the longitudinal direction of the sash member 107.1 against each other, but for the raising and lowering of the wing 106 are drivingly connected to each other. Each carriage 111 is attached to a carriage carrier 114 at the bottom 113.1 of the groove 113 in a suitable manner, for example by screwing. The carriage rollers 112 are freely rotatably mounted on a carriage or running shoe housing 115. The carriage housing 115 is connected for lifting and lowering of the wing 106 with the carriage carrier on the lifting means, which are formed in the simplest case of a lifting cam on the carriage carrier 114 and a cooperating with this lifting cam guide or sliding pin on the carriage housing 115.

The depth of the groove 113 is selected so that, at least when the wing 106 is lowered, the carriages 111 with all their elements, including their carriage rollers 112, are almost completely received in the groove 113. At its open side, the groove 113 is slightly widened, ie provided on both sides with a recess 116 so that each side surface 113.2 of the groove in the region of these recesses each forms a step with a surface 113.3, which lies in a plane perpendicular to the median plane of the groove 113 ,

On both sides of the groove 113, two additional grooves 117 are still introduced into the sash member 107.1 and in the corresponding wooden profile, and indeed for receiving seals, not shown, which seal the closed wing 106 relative to the frame 102.

The FIG. 12 shows a section through the vertical sash frame element 107.2 of the sash made of wood frame 107. Also in the sash member 107.2 is at the fold or at the closed wing 106 of the frame 102 adjacent outer side of the sash 107 again the groove 113 with the two recesses 116th and introduced with the additional grooves 117 for the seals. The groove 113 serves to attach the faceplate 118 of the aforementioned espagnolette fitting. The faceplate 118 is formed as a flat, band or strip-like (flat-band-like) rail and anchored via suitable fasteners 119 in the groove 113, in such a way that the faceplate 118 on its groove 113 facing side in an edge region of its longitudinal sides against the The recesses 116 formed surfaces 113.3 rests and covers the groove 113 to the outside. Within the groove 113, a likewise flat band-like drive rod 120 is slidably guided on the face plate 118 in the longitudinal direction. The drive rod 120 is drivingly connected to the gear 110 and controls, inter alia, via a not shown Eckumlenkung, as for example, those skilled in the DE 203 04 001 U is known, the carriage 111 for raising and lowering the wing 106th

By the two recesses 116 and by the contact surfaces 113.3 formed by these recesses, it is possible to form the faceplate 118 flat-band-like and yet reliably and accurately attached to the sash frame 107 in the region of the groove 113.

The flat band-like design of the faceplate 118 has, in addition to, in particular, a material and cost saving in particular also the advantage that the groove 113 at least outside of the recesses 116, ie over the greater part of their depth can be made relatively narrow, ie the groove width can be reduced from the current standard width of about 22 mm to about 16 mm, which at the same outer dimensions of the wood frame used for the sash 107 to a substantial increase in the strength of the sash 107 and thus u , a leads to an increase in burglar resistance, or allows a more compact design, in particular by reducing the dimensions of the profile used for the casement 107.

The FIG. 13 shows a section through the upper horizontal sash element. Also there again, the groove 113 is provided with the two recesses 116, together with the provided on both sides of the groove 113 grooves 117 for the seal. In the groove 113, an H-shaped profile 121 is inserted on the casement element 107.3 and secured in a suitable manner. On the profile 121, a guide piece 122 is resiliently mounted in one piece, with which the wing 106 is guided on its upper side, ie with its sash element 107.3 on the frame 102 for raising and lowering and for moving.

As the FIGS. 11-13 show is in all sash elements 107.1, 107.2 and 107.3 the local, necessary to accommodate the functional elements groove 113 formed identically, which also means a significant simplification and cost savings in manufacturing, since each same tools for the grooves 113 on all sash elements 107.1, 107.2 and 107.3 can be used.

Another significant advantage consists in the fact that each groove 117 is located on a sash element 107.1 - 107.3 in a common plane with the corresponding groove on the other sash elements, so that the recorded in the grooves 117 of the sash elements 107.1 - 107.2 seals performed as a continuous seals can be and thus optimal sealing is achieved with the wing closed 106.

The FIGS. 14-16 show cuts similar to the FIGS. 12-13 However, in a wing frame 107a, the sash elements 107a.1, 107a.2 and 107a.3 are each formed by a multi-chamber plastic profile with an internal metal reinforcement 123. In this embodiment as well, the groove 113 with the two recesses 116 and with the contact surfaces 113.3 formed by these recesses and with the additional grooves 117 is again provided in all casement elements 107a.1, 107a.2 and 107a.3. In the case of the casement element 107a.1, the groove 113 again essentially serves to receive the two carriages 111, the casement element 107a.2 for receiving and fastening the flat-band-shaped cuff rail 118 with the drive rod 118 and the casement element 107a.3 for receiving the H profile 121 the guide piece 122.

Thus, it is of course possible that with the drive rod 118 locking elements or locks are actuated or such closing elements or latches are provided on the drive rod 118.
