EP0763644B1 - Window/door with locking positions between pivot/tilt frame and fixed frame - Google Patents

Abstract

A hinged door or window, or pivoting window, has a pair of sensors on the fixed frame opposite the hinged edge and a rod in the corresponding edge of the moveable part which slides from one position, when the door or window is closed, to another when open. Fixed position sensors monitor the position of the rod to indicate the status of the door or window. The window or door (1) has a hinged frame (3) and fixed frame (4) and one or more closed positions (2) comprising locking slots (5), locking bolt (6) and an operating slider (7). The slider moves the locking bolt from one position (10) when the door or window is closed to a second position (11) when fully open. A pair of sensors (8.1,8.2) detect which position prevails.

Description

The present invention relates to a window / door Locking points between the tilt and turn sash frame and the fixed one Frame according to the preamble of claim 1.

Such windows / doors are e.g. known in connection with optoelectronic lock monitoring for both Locking as well as for the tilting of the window sash.

Other designs are known, e.g. Document EP-A-0 599 809, in which, however a tilt position query does not take place. In these versions becomes a so-called at the top of the window sash Contact redirector installed, which indicates the closed state the window via a corresponding evaluation circuit centrally displays.

The present invention is based on the object reduce the amount of electrical installation required, without compromising the achievable security.

This object is solved by the features of the claim 1.

The advantage of the invention is that both the tilt position and the closed position only a single locking point is queried, the special feature there is that the locking partners: entry slot and Locking bolts not only in the locked position, as usual, but also in the tilt position in the are mutual interference.

It is therefore with the display signal: window in tilt position not only this information available, but about it also the information: locking bolt of the tilt position is located in the associated entry slot.

The invention is therefore essentially based on a further improve those windows / doors where the Tilt position also due to an engagement between locking bolts and entry slot on the lower frame cross member Attempted levering is secured.

The invention is therefore with the conventional systems not comparable. With the conventional systems indicated that the sash is in the tilt position. In order to however, the information is not connected: casement secured against attempted levering along the tilt axis.

This advantage of the invention additionally creates the possibility all three possible positions between the entry slot and locking bolts.

As is known, the locking bolt moves relatively to the entry slot between two end positions. In the the sash is tilted in one end position, in the other The sash is closed in the end position. In between the sash is in the middle position Rotating position, i.e. openable.

This position can also with the present invention can be detected without additional wiring necessary is. This will be discussed later.

The training according to claim 2 additionally increases the Burglar resistance of such windows / doors in that the Reach behind the associated strikers and thus a lever-proof connection between the sash frame and offer fixed frames.

In addition, prying security is improved if the mushroom bolts are made of stainless steel. In this Trap is suggested a magnetic in the mushroom pin Integrate positioners. Since the mushroom bolt largely is non-magnetic, the resulting interference field low. The position encoder can work exactly.

For the arrangement of the sensors with associated position sensors versions according to claims 4 to 6 are conceivable. Exemplary embodiments are given for this.

If one forms position sensors and sensors such that these work together without contact, they are also highly wear-resistant and reliable continuous operation guaranteed.

The position transmitter can expediently be used as a permanent magnet and the sensor can be designed as a reed contact.

The invention thus already creates the necessary Security to inform about the current window condition.

In addition, it is now proposed that in addition to each Frame leg of the window of the door at least one more further pairing of sensor and position transmitter is provided, which only serve to monitor the lock of the window.

A signal is therefore also generated with these features, if tampered with the locked state of the window / door becomes. The signal can possibly lead to a break-in warning signal to be processed further.

To achieve additional security, it is proposed that the sensors for locking monitoring on the individual To connect frame legs in series. It is therefore sufficient an interruption of the closed circuit by only a single sensor to trigger the alarm. This applies in a corresponding manner even if the window in Tilt position is.

The invention is therefore particularly advantageous characterized in that thanks to the compact arrangement of sensors and position sensors not only the closed position, but the tilt position can also be monitored. Furthermore only the compact arrangement creates the possibility also signal the window open position. This can be done via an AND combination of the two Sensors, as well as via an OR link.

This state is advantageously displayed via a logic circuit which, in the absence of a locking position signal and when there is no tilt signal at the same time generates a window open signal.

There are therefore only two sensor / position sensor pairings three unique status signals can be generated.

The logic circuit consists, for example, of an inverter, which is positive if there are two negative inputs Output signal generated.

Thanks to the compact design and the low wiring effort existing windows / doors can Fit the frame with a prepared coupling line. If necessary, this can be via a data bus to a central Monitoring system to be kept to the condition of all windows / doors View and monitor centrally in a building to be able to.

Unless otherwise stated, the following description applies always for all figures.

The figures show window / door 1 with a tilt and turn sash 3 and frame 4. As is known, there is between Turn-tilt sash 3 and frame 4 one or there are several locking point (s) 2. The locking points 2 are formed by the locking partners: entry slots 5 and Locking bolts 6. The locking bolts 6 are relative movable to the entry slots 5. This is done via a Driving rod 7 of the window fitting. One of the locking partners is fixed, here the entry slots 5 while the other locking partner with the drive rod 7 of the window fitting is driven. This is here with the locking bolts 6 the case.

The locking bolts 6 are available in pairs. Each a locking bolt acts with an entry slot 5 together. The other locking bolt is in each case disengaged.

About the window handle is the drive rod 7 of the fitting between the closed position shown in dotted lines and the tilt position shown in dashed lines moves. The locking bolts 6 are taken synchronously and from one end position to the middle position in brought their other end position. The first end position is the closed position 10. The window cannot be opened become. The other end position is the tilt position 11, the window can be tilted. The middle position between the end positions 10,11 is the window open position, in which the window can be opened.

It now applies to these three possible positions between To interrogate locking bolts 6 and insertion slots 5 that a unique status can be displayed.

This is done in that at the closing point 2 at the bottom Crossbar of the window / door two sensors 8.1,8.2 are arranged where the with the drive rod 7 of the fitting connected locking partner with his stationary Locking partner is engaged. On the one hand, this is the Locking partner of the closed position 10 and on the other hand the Locking partner of the tilt position 11 meant.

It is therefore both at only one locking point 2 the locking position 10 and the tilt position 11 are queried.

It can therefore be done with just one line a single locking point 2 the position query between Locking pin 6 and entry slots 5 clearly recorded become.

Figure 1a shows another detail: the one shown there Locking point 2 has the fixed on the frame 4 Sensor 8 on. In addition, with the frame 4, the entry slot 5 rigidly connected. The drive rod 7 does not take only the position encoder 9 but also the locking bolt 6 and consequently also moves position transmitters with its movement 9 together with the locking bolt 6. The locking bolt is located 6 in engagement with the insertion slot 5, so the position transmitter 9 is exactly aligned with the sensor 8, the associated one Signal: Window closed, can thus be generated. If the drive rod 7 is guided out of the locking position 10 in the middle position 15 (see Fig. 2) so the position transmitter leaves 9 the aligned position with the sensor 8. The associated signal remains off. However, this is not yet clear Signal for the window open position.

Therefore, this state should first of all be based on FIG to be explained further. Namely, the drive rod 7 of the fitting is driven to the right, so the drive rod 7 also the fitting part, generally designated 24 driven. This fitting part 24 is drive-proof with the Drive rod 7 connected. If you move the fitting part 24 together the drive rod 7 to the right, so the right Mushroom pin 6 of the fitting part 24 engages at some point the associated entry slot 5 on the frame 4. Here The position sensor 9 runs over the associated sensor 8.2. The tilt position 11 is thus clearly reached. The tilt position signal can be generated.

In the middle position 15 shown, however, none of the Position transmitter 9 in alignment with its associated sensor 8.1 or 8.2. Therefore neither sensor 8.1 nor sensor 8.2 generates an associated output signal. Therefore, from missing out both signals are concluded that the window fitting in is the window open position.

This can be done using the inverter circuit shown in Fig. 8 generate a positive output signal 19. The inverter 16 has two negated inputs 17, 18. Each of the entrances is with the corresponding signal for the closed position 10 or tilt position 11 acted upon. In the absence of both Signals takes place in the inverter 16 an inversion, so that a positive Output signal 19 is generated, which for display of the casement can serve when the window is open.

As can also be seen from FIG. 2, there are the locking partners on the one hand from mushroom bolts and on the other from entry slots that run in the longitudinal direction of the fitting. It is essential that the mushroom bolts with their extended heads the retracted slots when retracted reach behind. The back zones between Mushroom bolts and the entry slot therefore prevent them from being pried open. Mushroom bolts made of high-strength create additional security Stainless steel, e.g. Chrome nickel steel, in this case it is suggested that according to Fig.2 in the mushroom bolts a magnetic Position encoder 9 is inserted.

3 to 5 now show different arrangements between Sensors 8 and position sensors 9.

According to FIG. 3, a pair of sensors 8.1, 8.2 sit at a distance from each other. In this case it is suggested with the drive rod 7 of the fitting a position sensor 9 to connect firmly. The path of the position encoder must in this case at least the distance between the two sensors 8.1.8.2 correspond.

If this is not the case, two can be provided Provide position encoder 9, of which, however, only one is in alignment with its associated sensor, possibly in the Window open position but neither of the two position sensors, to get a clear output signal here too reach.

In contrast, Fig. 4 shows that a single position transmitter 9 in conjunction with two sensors 8.1 and 8.2 on the Driving rod 7 of the fitting can interact.

Fig. 4 shows that the position sensor 9 both from the one sensor 8.1 and the other sensor 8.2 can be run over. This ensures that only a single sensor with the position sensor 9th flees. Even with this arrangement, in the absence of a Output signal of both the sensor 8.1 and the sensor 8.2 clearly close the window open position.

Fig. 5 also shows that a combination of two position sensors 9 with two sensors 8.1,8.2 is conceivable. Here the sensors are firmly connected to the drive rod 7. The position sensors 9 are fixed in place on the frame 4.

The exemplary embodiments shown also showed that position transmitter 9 and sensors 8 interact without contact. This offers the advantage of permanently avoiding wear.

In one embodiment, the position transmitter is proposed as a permanent magnet and the sensor as a reed contact to train. To avoid additional wiring, In this case, the sensor / should be the sensors stationary and the position encoder (s) on the casement to sit.

In addition, Figures 6a, 6b show that single and multi-leaf Windows at least on each frame leg a pairing of sensor and position sensor is provided can be. This pairing expediently becomes approximately in the middle sit on the frame leg. This is a frame monitoring 12. This frame leg monitoring 12 only serves to monitor the closed position of the Casement. The frame leg sensors 12 are in series switch to when opening the circuit as a result of a pry attempt trigger the corresponding alarm.

In addition, Figure 4 shows the arrangement between position transmitter and sensor. In this case, the position transmitter designed as a permanent magnet 13 and the sensor as a reed contact 14. The position transmitter sits in a fold overlap of the sash 3, while the sensor in a longitudinal groove of the Air gap area of the window is attached. This offers the The advantage of simple cable routing within the rebate groove 25. Since this rebate groove is usually inside the room sitting on the frame 4, there is also a risk External manipulation is extremely low.

Fig. 9 also shows that on each frame 4 a coupling line 20 can be provided. The coupling line 20 is connected to the House installation connected. The connection happens with regard on a data bus line 21 which is inside the house to be installed on site.

The constellation for windows I and II is shown of a room. It is also planned to use another one Signal line 26 to monitor another room.

All reporting lines go to a central office 22.23, to show the state of the window there.

With the present invention, both the closed position, as well as the tilt position, as well as the window open position displayed separately. Especially in Connection with a logic circuit according to Figure 8 can therefore with only two sensors 8.1, 8.2 both the tilt position, as well as the closed position, as well as the window open position monitor.

In addition, a display device can be provided with the central house 22 23 connected to specific information thereon display legible.
