Description

The invention relates to a window or door with fitting according to the preamble of claim 1.

Generic windows or doors have already become known. Increasingly, fittings for windows and doors with motor drives are offered. This also applies to windows and doors - there are only doors after that - which can be moved vertically or horizontally. The wing is held in a vertical sliding wing in lateral running or guide rails. The connection is made via guide pieces, which are attached directly or indirectly to the wing and are received in the rails. Depending on the sash weight, it may be provided that the sash weight is received via a relief device, so that the operator only has to apply small forces during a manual operation.

A generic door was presented to the public at the BAU 2005 trade fair in Munich. The Atrium HS 300E electric lift-and-hang door has a driver that couples the wing to a drive link installed in a rail and also carries a cable for electrical power to a wing-mounted hardware drive. The driver protrudes from the fold of the upright wing frame spar and engages in a mounted on the frame viewing surface rail. The introduction of force via the drive therefore causes a certain torque around the attachment point on the wing in the case of heavy wings. A stable and torsion-free connection of the driver is therefore desirable.

In a horizontally displaceable wing a running rail is provided at the lower or upper horizontal frame edge, which receives the weight forces via a carriage. The carriage transfers the weight of the wing to the frame while the guide rail stabilizes the wing.

If the wing is driven by a motor, then the drive engages via a driver on the wing. The driver is a separate component which is provided only in a motor-driven wing, so that guide pieces, carriages and rails with manual and motorized operation can remain essentially unchanged. The motor drive engages with e.g. guided on the guide rail band on the unlocked to open wing on the driver and pulls this with.

In the case of a wing which is lowered in the closed position, the lifting device, which is usually integrated in the carriage, must first be activated. For this purpose, the drive rod fitting of the wing, which is in drive connection with the lifting device, a second drive in the form of a motor assigned. This acts on the espagnolette fitting and is movable together with the wing.

From the EP 1 507 059 A2 a fitting has become known which tries to dispense with the use of a second motor. As a result, it is no longer possible to move the wing independently of the drive, for example, to bring this in a lowered position when the wing is open.

In a known fitting according to the stop instructions Atrium HS 300E of Hautau provided that an electric drive acts on the espagnolette fitting. This drive is mounted in an opening of the wing and is powered by a cable that leads from the frame via the driver on the wing. The cable is guided on the driver in an open groove and is coupled with a plug to the drive.

The driver is inserted into a drive-side clamping piece, from which a cable with plug exits. The cable is laid unsecured in a groove of the driver. Subsequently, a connector must be closed between the wing and driver, although the driver is not yet finally positioned. This creates excess cable, which is awkward to stow in the wing.

The invention is therefore based on the object to find an arrangement that allows easy installation of the cable and the driver. In particular, the laying of the cable to and in the wing should be improved.

The solution of this object is achieved by the means described in claim 1.

With the features of claim 1 also a safe and resilient connection of the driver is achieved on the wing. The installation of the cable and the driver is simplified and the cable is securely received.

Characterized in that the base plate has one or more projecting trunnions associated with the respective holes in the wing, on the one hand can increase the carrying capacity of the base plate and on the other hand, the placement of the base plate on the wing easily find. The trunnions are inserted into holes which are attached, for example by means of a drilling template on the wing. Thus, the position is set relative to the wing quickly and safely.

The connection of the driver and the base plate can be improved, in which the driver and the base plate are connected via a positive connection and the base plate is received in a recess of the driver.

A simple embodiment of the driver may provide that the driver has an S- or Z-shaped contour, wherein an end leg has the recess.

It is also useful if the driver and the base plate together form a strain relief and pinch the cable between them.

In order to achieve a coupling to the drive is further provided that the end leg forms a clamping part. The connection to the drive can be achieved via this clamping part integrated in the driver.

It can also be provided for attachment, that in the base plate and the driver coaxially extending holes are provided for mounting screws. Both parts can be attached with common fasteners in one operation on the wing.

The assembly can be further facilitated by the fact that a means for provisionally fixing the cable is provided on the base plate.

To lay the cable on the rebate side of the wing, an open-edged recess in the wing be attached, which is at least partially closed and covered by the base plate again. Preferably, however, it is provided that the cable is laid through a hole in the wing on the folded side and thereby passes through a hole or opening in the base plate. The hole for the cable in the wing can be made together with the holes of the trunnions.

In the Fig. 1 is the fixed frame 1 with and the liftable and movable wings designated 2. The wing 2 is provided with a fitting 3, which comprises two carriages 4 and 5, an espagnolette 6, a lower running rail 7 and an upper guide rail 8.

In the Fig. 2 are the essential components of the fitting 3 without the wing 2 in an overview.

The carriages 4, 5 are connected to each other via a connecting rod 9. At the front carriage 4 is a corner gear 10 for deflecting a generated by the espagnolette gear 6 movement of a - not shown here - thrust member or a drive rod of the adjusting mechanism. On the frame 1 locking members 11, 12 are provided. To actuate the espagnolette drive 6, a motor drive is provided which in the Fig. 1 designated 39.

The front carriage 4, which is formed substantially the same as the rear carriage 5, is in Fig. 3 shown in detail. On the roller carrier 13 two spaced-apart rollers 14,15 are rotatably mounted, which rest on the symbolized by a dash-dotted line track 7 at the bottom or a lower frame frame spar. The front end of the roller carrier 13, which is not shown here in the direction of displacement 16 of the blade 2, is pivotally connected to a connecting link 17, which in turn is rotatably mounted on a bell angle 18. The latter can be pivoted on a bearing bolt 19 arranged at the screw 20. Its other end is coupled via a further rotary joint 21 with a connecting lug 22. The Anschraubwinkel 19 is fixed by means of - not shown - screws on the wing 2. This in Fig. 2 shown espagnolette 6 has a U-shaped guide rail for the movable up and down drive rod. Via a coupling device 24, the drive rod and the terminal lug 22 of the corner gear 10 is connected.

This causes an up and down movement of the drive rod in the direction of the double arrow 23 (FIG. Fig. 2 It causes in turn a rotation of the bell angle 18 about the bearing pin 20 and thus a displacement and simultaneous pivoting of the connecting plate 17 about the bearing axis 29 on the roller carrier 9. An upward movement of the drive rod therefore has a displacement of the roller carrier 13 with respect to the Anschraubwinkel 19 and thus also relative to the wing 2 in the direction of arrow 16 result.

In the roller carrier 13 is stored as a casserole member 30, a lifting roller. It engages in an arcuate guide slot 31 of the guide body 32 fixedly connected to the screw-on angle 19. The lower, in Fig. 3 the left end 33 of this guide slot 31 runs almost horizontally. In addition, it can be used as a stop for the casserole member 30. Now, if the drive rod is moved upwards, so this has a displacement of the casserole member 30 from right to left result. Due to its connection with the guide slot 31 causes this sideways movement of the lifting roller (casserole member 30) lifting the guide body 32 and thus the wing 2. This lifting movement is continuous over the entire duration of the lifting movement of the drive rod and constantly upwards. A reversal of motion takes place only with a downward movement of the drive rod. In the raised position, the wing 2 can be moved relative to the frame 1, in the lowered position, the wing 2 on the locking members 11, 12 fixed to the frame 1.

In the FIGS. 4 and 5 the motor drive 39 is shown in detail. From the Fig. 4 it is clear that the motor drive 39 consists of a motor 40 and a gear 41 associated therewith, which are mounted on a mounting plate 42. The coupling with the drive rod gear 6 via a square shaft 43 ( Fig. 5 ). The motor drive 39 can thereby be used in place of the otherwise to be provided manually operable hand lever. The espagnolette 6 and the fitting 3 in itself remain identical.

From the schematic representation of the Fig. 5 the structure of the motor drive 39 is apparent. The motor 40 is designed as a fast-acting low-voltage drive, which is geared down to the output shaft 45 via different gear ratios 44a, 44b and 44c. The output shaft 45 is designed uniform with the square shaft 43 and rear has a shaft extension 46 with a tool engagement 47.

Further, the shaft 48 of the translation stage 44b is axially slidably mounted in the gear housing 49 and provides at one end via the gear housing 49 before. The shaft 48 is subjected to force via an energy storage device in the form of a compression spring 50 in the direction of the visible surface. If the shaft extension 51 of the shaft 48 moves in the direction of the arrow 52, counter to the effective direction of the compression spring 50, the transmission stages 44a and 44b are decoupled. As a result, an emergency operating function can be effected in the case of an inserted tool 53, since the required manual operating force can be substantially reduced by the elimination of the gear ratios 44a and thus of the motor 40.

The tool 53 is housed in the use of the door in a housing 54, 55, which covers the motor drive 39. In the event of failure of the motor drive 39, e.g. due to a power failure or similar the door can be opened by removing the housing 54, 55 and pressing the shaft extension 51 by means of the inserted tool 53.

From the Fig. 4 It is also clear that the supply of the motor drive 39 with energy via a cable 56 takes place, which - as from Fig. 6 emerges - is laid in the fitting groove 60 of the wing 2. The fitting groove 60 is designed as an open groove in the folding surface 61 of the wing 2 and has a rectangular cross-section. Here is the espagnolette fitting included, as in connection with Fig. 7 is clear from the espagnolette 6. The drive rod gear 6 has a substantially U-shaped rail 62 which terminates with the folding surface 61. In the rail 62, the drive rod 63 is slidably guided in an undercut 64.

On the groove base 65 of the fitting groove 60, a guide piece 66 is attached, which has a bore 67 for the passage of a fastening screw 68. The fastening screw 68 passes through the hole 67 and the rail 62 in a hole provided for this purpose 69. The guide piece has a substantially W-shaped cross-section, which projects through a protruding in the direction of the groove bottom 65 center web 70 and against the recessed side bars 71, 72 and thereof directed in the direction of the groove bottom 65 edge strips 73, 74 is formed. Between the edge strips 73, 74 thereby provided along the longitudinal center axis and the central web 70 extending U-förmige.Aufnahmen 75, 76, which serve to receive the cable 56. The cable 56 is thereby guided on both sides of the central web 70, in which the bore 67 is mounted.

The laying of the cable 56 on the wing 2 is thereby considerably simplified, since the cable 56 can be attached before the attachment of the fitting 3. The cable 56 is guided by the guide piece 66 around the area in which mounting screws 68 could be attached. Thus, damage to the cable 56 is precluded when the mounting screw 68 is attached.

The assembly of the guide piece 66 can be done in different ways.

On the one hand can be provided that the guide piece 66 is attached to the wing 2, before the fitting 3 is mounted. This requires the knowledge of the exact location of the mounting screws 68, so that they can enforce the bore 67. The location of the holes 69 in the rail 62 is generally known or can be determined by measurement. The guide pieces 66 are then at the groove bottom 65 by means provided for this purpose and not shown fastening screws, which enforce the longitudinally - along the longitudinal center axis 77 of the central web 70 - attached mounting plates 79. The Anschraublaschen 79 are designed as longitudinal extensions of the central web 70 and project beyond the receptacles 75, 76, so that when attached by means of the fastening tabs 79 passing through the screws 56 remains visible and not accidentally gets under the central web 70 and then damaged.

Alternatively, however, it can be provided that the guide pieces 66 are attached to the rail 62 and the rail 62 is used as a jig to determine the positions of the fastening screws 68. The edge strips 73, 74 have this locking means 77 which cooperate with the rail 62 of the fitting - here the espagnolette gear 6 -. The resilient edge strips 73, 74 have outwardly projecting longitudinal beads on ( Fig. 8 ), which engage in longitudinal grooves of the rail 62. As a result, the guide pieces 66 can be releasably fastened to the rail 62 when not yet mounted, and the bores 62 can then be predrilled together with the rail 62. Subsequently, the guide pieces 66 are removed from the rail 62 and in the fitting groove 60 together attached with the cable 56. The rail 62 and the espagnolette gear 6 are then introduced in a second operation in the fitting groove 60 and temporarily fixed by the guide piece 66 until the fastening screw 68 is introduced. In particular, the advantage of temporary fixation also results in the first case of assembly.

In order to compensate for minor assembly inaccuracies is provided that the bore 67 is formed as a slot, as in the Fig. 8 shown. As a result, slight deviations in the position of the guide pieces 66 relative to the rail 62 can be compensated.

In order to hold the cable 56 in the receptacles 75, 76 is provided that the central web 70 is provided with in the direction of the edge strips 73, 74 projecting latching hooks 78, which engage behind the cable 56 or at least a part thereof. As a result, an escape of the cable 56 from the receptacles 75, 76 is avoided during assembly. It may also differ from the illustration according to the FIGS. 7 and 8 be provided that the receptacles 75, 76 have different shapes and dimensions to the requirements of different cables 56, for example, for the signal transmission on the one hand, or the provision of energy on the other account. Also, the use of the guide pieces 66 is not limited to fittings of the type described. The guide pieces 66 are also used in fittings that provide other types of opening.

It is expedient to produce the guide piece 66 as a molded part made of plastic, since this allows the required elastic properties to be combined with cost-effective production. The guide piece is formed symmetrically with respect to the longitudinal and the transverse center axis in the illustrated embodiment.

From the Fig. 6 It can be seen that the cable 56 is guided to the upper horizontal wing leg 80 and here - without a fitting 3 is provided with a rail 62 - is also attached to the guide pieces 66. Excess cable 56 is thereby fastened in a loop 81 in the otherwise unused Beschaltungsut 60 and passed to the driver 82 which is fastened approximately centrally on the wing leg 80.

The driver 82 is shown in the Fig. 9 for coupling the wing 2 with a motor drive 83 which is mounted on the upper horizontal frame leg 84. The drive 83 is driven here by means of electrical energy and has a drive belt 85 which can be attached to the driver 82.

The driver 82 is, as from the FIGS. 10 and 11 can be seen, with a base plate 86 attached to the wing 2. The driver 82 has an S or. Z-shaped contour on. On an end leg 87, a receptacle 88 for the drive belt 85 is provided, which can be clamped in the slot-shaped receptacle 88 by means of screws 89, 90, wherein the end leg 87 forms a clamping part as a whole.

At the end leg 91, a recess 92 is mounted, which is dimensioned complementary to the base plate 86, so that it is completely covered in the assembled state of the driver 82. For this purpose, the recess 92 is formed by webs 93 which project edge-like on the end leg 91. Driver 82 and base plate 86 are connected via a positive connection, which is additionally secured by the fact that in the base plate 86 and the driver 82 coaxially extending holes 94, 95 are provided for mounting screws 96. By this, the driver 82 and the base plate 86 are fastened together on the wing 2.

The base plate 86 has two projecting trunnions 97, 98, the corresponding holes 99 are assigned in the wing 2. About the trunnions 97, 98, the occurring shear forces can be transferred very well. If the wing 2 is moved over the drive belt 85, so occur on the driver 82 in addition to the forces for moving the wing 2 and moments, which are due to the distance of the end leg 87 to the attachment point on the wing 2. Both force components must be transmitted to the wing 2 and are dependent on the weight of the wing 2 and the acceleration with which the motor drive 83 tries to drive the wing 2. In addition to an increase in the carrying capacity of the base plate 86 and the form-fitting attached thereto driver 82, the placement of the base plate 86 is improved on the wing 2 in a simple way to another. The trunnions 97, 98 are inserted into the holes 99, which are attached to the wing 2, for example, by means of a drilling template prior to assembly. Thus, the position of the driver 82 is set relative to the wing 2 quickly and safely and it is also ensured by two trunnions 97, 98 that the orientation of the receptacle 88 is exactly parallel to the wing edge. An undesirable distortion of the drive belt 85 is thereby avoided.

When attaching the holes 99 may also have another in the Fig. 10 indicated bore 100 are provided, which forms a passage for the cable 56. Through the hole 100, the cable 56 on the folded side - here the folding surface 61 - laid. For this purpose, the cable 56 passes through a bore 101 (FIG. Fig. 11 ) in the base plate 86.

The base plate 86 has an L-shaped guide leg 102 which serves to receive and guide the cable 56. The guide leg 102 is formed as a curved U-shaped channel, which is open in the direction of the driver 82, so that the cable 56 can be led away perpendicularly after passing through the bore 100 without kink. In the guide leg 102 are means in the form of latching hooks or cable ties o.ä. attached, a provisional fixation of the cable 56 in the channel enable.

In the driver 82, a groove 103 is provided, which is dimensioned complementary to the guide leg 102. To form a strain relief and pinch the cable 56 between them are provided on the driver 82 in the direction of the guide leg 102 projecting clamping means which narrow the channel to a necessary for the cable 56 degree.

The base plate 86 may preferably be designed as a plastic molded part. However, it may be useful in particular to increase the carrying capacity to design the base plate 86 as a metal molding and to attach the guide leg 102 as a locking part of this metal molding. The support pins 97, 98 are in this variant to be welded to the base plate 86 or fixed at least by plastic deformation.
