Description

The invention relates to a window or door system for buildings according to the preamble of claim 1.

From the WO 2017/016809 A1 a lock for a window or a door has become known in which the sash, which is movably mounted with respect to a frame, is to be fixed to the frame by means of the lock. The closure consists of a closure element which is attached to the sash or frame and when the open sash is closed from a release position by the movement of a locking element interacting with the closure element, it moves into a locking position in which the locking element is fixed by the closure element and this against the Opening direction blocks. A motorized drive is also provided which, when activated, moves the closure element into its blocking position.
The disadvantage here is that each locking point on a window equipped with such a lock must be provided with several of these locks in order to meet the requirements with regard to tightness and security. In addition to the associated costs for each motor, the necessary connection of all motors must be provided.

The EP 1842992 A2 discloses a lock for a hood of a motor vehicle, in which a bracket is attached to the movable hood, which is engaged from behind by a catch hook. For this purpose, the catch hook is pivoted and forms a claw, the opening of which points in the unlocked position in the direction of the bracket and which pivots as a result of the penetrating bracket and is provided with a primary and secondary locking mechanism for unlocking, the catch hook is pivoted back manually. This configuration is suitable for a motor vehicle, since only limited requirements are placed on a hood in terms of tightness and protection against burglary.

The invention is therefore based on the object of providing a simplified and easy-to-use window system, which can be manufactured inexpensively and ensures secure locking.

To achieve this object, it is provided in a generic window system that each locking system is connected to each other locking system via a circumferential force transmission element which actuates the release device. This reduces the function of the power transmission element to a minimum and is only used for unlocking. At the same time, every time the sash is closed, it is automatically locked.

A particularly simple embodiment provides that the force transmission element is a cable pull. This considerably reduces the cost of materials.

In order to achieve a circumferential, smooth and easy-to-clean fold, the frame can have pockets that are open on the inside to accommodate the closure elements. This configuration is particularly useful when the frame is made from a solid material.

If, on the other hand, the frame is composed of hollow profile rods, it can advantageously be provided that the closure elements are attached to the rebate surface of the frame and a filler profile is arranged between the closure elements and each further closure element or a frame corner. A smooth fold is achieved through the filling profile.

In order to attach the force transmission element to the frame in a protected and inconspicuous manner, provision is made for a circumferential frame groove facing away from the inside of the pocket to be provided, which accommodates the force transmission element. This frame groove is directly adjacent to the closure elements and thus allows direct access of the force transmission element to the closure element.

If a deflection element is provided on each frame inside corner, which controls the movement of the force transmission element on the adjacent frame limb transmits, then the locking elements on each frame spar can be operated simultaneously, if necessary.

In order to achieve motorized unlocking, it is now sufficient for an electromechanical actuator to act on the force transmission element and cause an unlocking movement of the force transmission element. The unlocking requires little force and a short travel, so that the actuator can be made small and inexpensive.

The window system is particularly simplified by the fact that the closure element is a passive, fixed pin which is arranged in a groove in the insulating web of a stepped glass pane. This makes it possible to attach an effective and force-transmitting closure element to a wing consisting largely of glass and to arrange the mechanism in a small space on the frame.

In order to bring about an opening in the event of a power supply failure or in an emergency, a manually operated emergency release element that acts on the power transmission means can be provided on the frame.

That in the Fig. 1 The window 1 shown has a frame 2 and a sash 3. The sash 3 is connected to the frame 2 via an articulated connection known per se so as to be pivotable about a vertical lateral axis. A mounting frame 4 is attached to the frame 2 or formed in one piece with the frame 2. This attachment frame 4 is dimensioned in such a way that its end face runs approximately flush with a pane of the sash 3 on the inside. This configuration is referred to as flush.

The Fig. 2 shows an inner frame corner 5 of the window 1 of the window system without the sash 3. The frame 2 has a smooth rebate 6. In the fold 6 pockets 7 are attached, in which closure elements 8 are received. The closure elements 8 are provided with an opening on the end face 9 of the frame 2 on the inside of the room. The closure element 8 lies flush with the fold 6 and the end face 9. The pocket 7 borders on the rear side 11 facing away from the inside 10 of the room in a fold groove 12. The fold groove 12 is closed with a cover rail 13.

As from the Figs. 2 and 3 As can be seen, a deflecting element 14 is located in the inner frame corner 5 in the immediate corner region of the rebate groove 12 Closure elements 8 are connected to one another via a force transmission element 15. In the exemplary embodiment, the force transmission element 15 is a cable pull 16 which is guided on the rear side 11 of the closure element 8 in the rebate groove 12 under or in the cover rail 13. The deflecting element 14 ensures that the rope is diverted to the respective adjacent frame limb. It is advantageous that a deflection element 14 is provided on each frame inner corner 5, which deflects the movement of the force transmission element 15 to the adjacent frame leg 27, so that a closed loop is formed. As a result, each closure element 8 is also connected to every other closure element 8. In a departure from this, however, it may also be sufficient not to design the force transmission element 15 closed and to place the ends in the closure elements 8

This is in the Fig. 4 shown. The locking system 17 comprises a number of locking elements 8 which are connected via the force transmission element 15 in the form of the cable pull 16. A locking element 18 of the wing 3, not shown here, is assigned to each closure element 8. The locking system 17 also comprises an electromechanical actuator 19 which is assigned to one end of the force transmission element 15 and applies a tensile stress to it when activated. An emergency unlocking module 20 is also provided and engages the force transmission element 15.

The Fig. 5 shows a vertical section through a window. The wing 3 has an outer disk 21 and an inner disk 22. A circumferential insulating web 23 connects the panes 21, 22, which are of different sizes, so that the pane 22 and the insulating web 23 protrude beyond the end face 9, while the pane 21 dips between the opposing folds 6 and 24. The insulating web 23 has a groove 25 which is offset from the rebate groove 12. The groove 25 serves to receive and fasten the locking element 18, which is not shown here. The installation space 26 for the pocket 7 for receiving the closure element 8 is indicated on the lower frame spar. This directly adjoins the rebate groove 12 and opens it. A ventilation duct 28 is provided on the upper frame leg 27. This connects the inside 10 of the room with the outside 29 of the building. The fold 24 can be partially removed to accommodate a locking or control means 30. The control means 30 terminates flush with the fold 24 and can also contain a forced ventilator and completely close the ventilation duct 28. The in the stacking frame 4 protruding beyond the end face, a groove for receiving a lighting strip is attached. In addition, the stacking frame 4 allows an electrical conductor to be laid.

The deflection element 14 according to Fig. 6 is an angular body with a TT-shaped cross-section, which is provided with a pulley 31 at the intersection of the legs. A rear groove 32 serves to accommodate the force transmission element 15.

In the Figs. 7 and 8 is a view of the closure element 8 without or with the bottom or cover plate in the unlocked state. The locking element 18 in the form of a cylindrical pin is indicated and is in an already approximated position to the closure element 8. The wing 3 is in this position in a non-parallel position of the wing 3 to the frame 2, which is shortly after opening or shortly before closing is achieved. The locking element 8 has a locking claw 33 and a locking lever 34. The locking claw 33 and the locking lever 34 are pivotably mounted on an L-shaped angled base plate 35. Two webs 36, 37 angled from the base plate 35 serve as stops for the edge 38 of the locking claw 33 and the cam 39 of the locking lever 34.

The locking claw 33 has a locking jaw 40 and is pivotable about the axis 41. The axis 41 is designed as a sleeve 42 and is penetrated by a fastening screw when it is fastened to the frame 2. An arm 43 protrudes over the base plate 35 and is provided with a bore 44. Two approximately orthogonal locking edges 45 and 46 point in the direction of the locking lever 34. A bevel 47 running transversely to the locking edge 45 opens into the locking jaw 40. The stop on the web 36 pivots the locking claw 33 up to the position shown. The locking lever is designed as a two-armed lever and the first arm 48 ends in the cam 39. The second arm 49, like the arm 43, projects beyond the base plate 35 and has the bore 50 here. A nose 51 protrudes almost at right angles from the axis which connects the arm 48 and the arm 49 to the axis of rotation 52. The axis 52 is also formed by a sleeve 42.
From the Fig. 8 it can be seen that the cover plate 53 is a simple flat plate with a bay 54 and forms a housing with the base plate 35, from which the arms 43 and 49 protrude.

In the in the Figs. 9 and 10 The locking position shown here pushes the locking element 18 sliding off the bevel 47 back into the housing. The locking element 18 dips into the locking jaw 40 and the edge 55 abuts the lip 56 ( Figures 7 and 8 ). This leads to a deflection of the locking lever 34 about the axis 52, in which the edge 55 slides under the lip 56. If the locking element 18 is completely immersed, the locking lever 34 swings under the influence of the only in the Fig. 10 illustrated spring 57 back. The locking claw 33 and the locking lever 34 engage behind one another with the locking edges 45, 46 and the nose 51 as well as the lip 56. As a result, the locking element 18 is reliably fixed and no actuation of a locking device is necessary for locking. The locking lever 34 allows locking of the locking edge 46 as well as the bevel 47 on the lip 56, so that a two-stage locking can take place. The spring 57 acts between the arms 43 and 49 and engages in the bores 44 and 50 here.

To achieve the unlocking is like in the Figs. 11 and 12 shown, only a pivoting of the locking lever 34 is necessary. The force transmission element 15 already described above brings about this pivoting, preferably by a pulling movement. The force transmission element 15 and the locking lever 34 form a release device. Pivoting causes the nose 51 and the lip 56 to move apart from the locking edges 45, 46. The spring 57, not shown here, is tensioned and exerts a clockwise torque on the locking claw 33 in the drawing. Until the locking lever 34 is disengaged, the locking element 18 holds the locking claw 33 in the Figs. 11 and 12 position shown and prevents a pivoting movement. If the locking claw 33 is released, the wing 3 can be opened and the locking jaw 40 pivots into the position shown in FIG Fig. 7 position shown, so that the locking element 18 can be guided out of the bay 54. The wing 3 is now unlocked and can be opened.

The decisive factor here is that the electromechanical actuator 19 only has to apply low forces and only travels in one direction. Actuator 19 does not need to be actuated for locking. The actuator 19 can, as in Fig. 15 shown schematically, act as an electric motor 66 inexpensive and small in size on a spindle 67. The spindle 67 carries a spindle nut 68 which carries along a coupling member in the form of a rod 69 by engagement of a pin 70. The Motor 66 moves back to its starting position immediately after the unlocking movement. The springs 57 of the closure elements 8 pull the coupling member 69 back via the force transmission element 15.
It can advantageously also be provided that the motor 66, proceeding from the starting position 71, also moves in the other direction and in doing so does not cause any movement of the force transmission element 15, but rather adjusts the air control means 30. This can be done in a simple manner by the engagement of the pin 70 on the spindle 67 in two elongated holes 72, 73 arranged offset to one another, a coupling device 74 with two short rods 69 and 75. The elongated holes 72, 73 only overlap in one end region in the starting position 71, in which the pin 70 engages in both elongated holes 72, 73. If the actuator 19 is actuated for unlocking, it only takes the rod 69 with it, which is connected to the force transmission element 15 for unlocking, and passes through the offset elongated hole 72 with the other rod 75. The springs 57 of the locking element 8 are positioned over the force transmission element 15 and the rod 69 coupled therewith against a stop 76. The second rod 75 remains motionless. If the actuator 19 is now operated in the other direction, it takes the second rod 75 with it and passes through the elongated hole 73 of the rod 69, which is connected to the force transmission element 15 and therefore remains without movement. The wing 3 remains locked via the locking elements 8. The rod 75 acts via a transmission member 77 on a ventilation flap 78, indicated schematically here, which is part of the control means 30, and opens it. The ventilation duct 28 is released. If, based on the actuated ventilation position, the wing 3 is to be unlocked, the actuator 19 moves into the middle position. The ventilation flap 28 is closed via the control means 30, for example by an adjustment path 79. In order then to effect the unlocking and the opening of the sash, the actuator 19 moves the pin 70, as already described above.

An advantageous method for operating a window system therefore provides that the window system has a locking system that automatically locks the sash 3 when it closes, consisting of a locking element 8 and a locking element 18, and the locking element 8 has a locking lever 34 which, by means of a force transmission element 15, consists of a Locked position can reach a release position, the force transmission element 15 by means of an electrical Actuator 19 is acted upon by force only in one direction starting from a first position.
It can advantageously also be provided that the travel 80 of the actuator 19, which it moves to unlock, is opposite a second travel 79 in the opposite direction, which does not move the force transmission element 15 and on this second travel 79 a covered between sash 3 and frame 2 attached ventilation device is operated. The ventilation device has the ventilation flap 78, known per se, which seals or releases the free space between the sash 3 and the frame 2 so that the ventilation duct 28 between the outside of the building and the inside of the building is released or blocked. Suitable control means 30 for blocking or releasing the ventilation duct 28 are already known in various configurations and in this regard the EP 1144792 B1 , the EP 2369253 A2 and the EP 2791452 B1 which are suitable to be addressed via the actuator 19.

The Fig. 13 shows the closure element 8 and the locking element 18 in a three-dimensional representation. The locking element 18 consists of a pin receptacle 60 and a pin 61 attached to it with the locking element. In the assembled state, the pin receptacle 60 engages in the groove 25 of the wing 3. It can be seen that the pin receptacle 60 is adapted to the shape of the groove 25. The pin 61 is preferably an eccentric mushroom head pin and its active surfaces can be adjusted relative to the pin receptacle 60. A cover 62 covers the closure element 8 and leaves only the bay 54 free for the engagement of the locking element 18.

From the Fig. 14 it becomes clear that the locking element 8 consists of the base plate 35 and the cover plate 53, which receive and store the locking claw 33 and the locking lever 34 between them. The base plate 35 and cover plate 53 have aligned recesses 63, 64. These recesses 63, 64 are used to latch the cover 62. The axes 41, 52 with the sleeves 42 are provided with countersinks 65 which receive the head of a fastening screw. The countersinks are preferably made at both ends of the axles so that the closure element can be mounted in different positions.

In the Fig. 16 the three possible positions of the electromechanical actuator 19, which consists of the motor 66 of the spindle 67 and the spindle nut 68, are shown schematically. In the position denoted by a), the locking elements 8 are in an unlocked position. The force transmission element 15 is a cable pull 16 which can only transmit tensile forces. In the unlocked position, the cable 16 is tensioned to the right in the figure and, facilitated by a free space or a guide 85 arranged in the rebate groove 12, the cable pulls a shaft 86 in the rebate groove 12 in the direction facing away from the closure element 8 In the middle position, the cable 16 is displaced by the travel 79. In the middle illustration according to b), the cable 16 is tensioned in a direction opposite thereto. The cable pull 16 now throws a shaft 87. The spring 57 of the closure elements 8 is corresponding to the Figs. 9 and 10 cocked and the wing 3 is locked. The end of the single cable pull 16 reaching to the control means 30 and the ventilation duct 28 causes the ventilation flap 78 to open and the ventilation duct 28 to be released. In c), the normal position of the drive is shown. The ventilation flap 78 is closed and the closure elements 8 are activated. The emergency release 20 rests on a driver 88 of the cable 16 and can, if necessary, move this together with the cable 16 to the right in the illustration and effect an unlocking. That in the Fig. 16 The illustrated embodiment requires only a single cable pull 16, which only partially wraps around the frame and is each tensioned by the functional members in the form of the closure elements 8 and the control means 30.

That in the Fig. 17 The illustrated embodiment is a simplified embodiment of the Fig. 15 presented facts. Two cables 16 are provided. Each cable pull 16 has a driver 88 at the end and at least one on the emergency release 20. In the locking position of the wing 3 according to illustration c), the drivers 88 lie on both sides of the driver 89 of the spindle nut 68 in the starting position 71. If the motor 66 is activated and the driver 89 is shifted to the left in accordance with position b), only the cable 16, which extends to the adjusting device 30 with the ventilation flap 78, is subjected to tension and the ventilation flap 78 is opened. The cable 16 reaching to the left to the locking elements 8 is not moved along with it and the driver 89 slides along this cable 16. If the motor 66 is driven in the opposite direction, as shown in the illustration a), then the locking elements 8 are unlocked and the Cable 16 in the direction of the ventilation flap 78 remains in its position without being moved.

The one in the Fig. 18 The view shown of a window 1 according to the window system has two ventilation duct openings 81 into which the ventilation duct 28 opens. Weather / insect screens 82 cover this. Inside the room is accordingly Fig. 19 having a view of the window after Fig. 18 shows from the inside, only a partial interruption 83 of the frame 2 can be seen.
