Remote control device.

p0001The invention relates to a remote control device for two identical, each remotely adjustable for up devices such as beds, a room, the first device having a first receiver and the second device is equipped with a second receiver and the first receiver a first wireless remote control transmitter and the second receiver a second wireless remote control transmitter are assigned, both remote transmitter buttons for controlling the various functions controlling receive channels of the devices have and each remote transmitter means of an additional switch is can be switched to the receive channels of one or other receiver, so that depending on the position of the auxiliary switch and the actuator one of the keys to one of the functions of one or the other device can be connected.

p0002There are known bedrooms devices in which the slabs are adjusted by motor on the two beds. To control can be provided an infrared remote control, wherein each bed is associated with its own remote control transmitter, so that each bed is adjustable separately.

p0003It is known, wherein a remote control device in which one of a plurality of receivers each requiring a separate transmitter is associated with build the transmitter so that they can be switched to a different receiver by means of an auxiliary switch. Here, the auxiliary switch is formed by a slide switch or button contacts. In both cases the switching of the transmitter from one to another recipient in such a way that an even setting will remain permanent and is only changed by a renewed switching again. Done The operator must therefore initially convince to which recipients of the respective station is tuned in, if he wants to avoid an erroneous operation of another receiver.

p0004Such a device is for remote control of the above-mentioned beds unsuitable because then the risk that inadvertently not the own bed, but the bed of the other is adjusted. The same applies if other, an operator associated facilities, such as bedside lamps and / or clock to be controlled with the remote controller.

p0005It is an integrated component SAA 3004 (Valvo) known on the market that is suitable for the construction of multi-channel, addressable transmitter.

p0006The object of the invention is to provide a remote control device of the aforementioned type in which usually each operator with his remote control transmitter can control only the functions of its device and in case of need the functions of the apparatus of the other operator, wherein an erroneous operation of the apparatus of the other is operator largely excluded.

p0007According above object is achieved with a remote control device of the aforementioned kind in that at two remote transmitters per a push button switch is provided as an additional switch that and as long as the key switch of the first remote control transmitter is operated then, which has buttons for the functions of the second receiver can be controlled and after the completion of the operation of this key switch with the key of the first remote control transmitter, the functions of the first receiver can be controlled and that then and as long as the key switch of the second remote control transmitter is operated, which has buttons for the functions of the first receiver can be controlled and after the operation this key switch with the keys of the second remote control transmitter functions of the second receiver are controllable.

p0008In this device, the operator must, if he does not want to use his own device, but his partner, one hand pressing the pushbutton switch of his transmitter and on the other hand the desired function controlled button. Thus the end result of a control function of the apparatus of the partner only by operation of the transmitter with two fingers is possible. It can therefore hardly accidentally a function of the apparatus of the partner to be driven. The operator does not visually convince on which receiver his station is tuned in. Thus can also be done in the dark a safe operation.

p0009Operation of the apparatus of the partner comes for example in question, when not temporarily able to operate its transmitter or he has changed this.

p0010After each release of the pushbutton the first remote control transmitter itself is set to be the functions of the first receiver drives with appropriate use. The same applies to the second remote control transmitter.

p0011In a preferred embodiment of the invention, each remote station on an integrated circuit having an address control terminal and address selection terminals, has two driven address selection terminals of the higher quality the priority. Such an integrated circuit is, for example, the block SAA 3004 (Valvo). The address control terminal is connected to a lower-value address selection terminal and, via a emitter-collector path of a switching transistor with a higher-value address selection terminal. Parallel to the emitter-collector path of the switching transistor is a voltage divider which consists of the push-button switch and a resistor, and whose tap is connected to the base of the switching transistor. At the first remote control transmitter of the push-button is located between the base and the collector of the switching transistor, while located in the second remote control transmitter of the key switches between the emitter and the base of the switching transistor. Thus the function described is realized in simple circuit design.

p0012In a further embodiment, the voltage divider has a reversible-polarity connection. It is thereby possible in the production to produce the first transmitter and the second transmitter identical. Through a corresponding insertion of the voltage divider, the transmitter is at a first or second transmitter.

p0013Further advantageous embodiments of the invention will become apparent from the following description of an embodiment.

p0014In the drawings:<ul><li>1 shows a view of a remote control transmitter,</li><li>Figure 2 is a diagram of a first remote control transmitter and</li><li>3 shows a diagram of a second remote control transmitter.</li></ul>

p0015An infrared remote control transmitter (1) has a plurality of keys (2). By pressing the buttons (2) can be a header, adjust an upper part and a foot part of a bed. The bed is equipped with a corresponding receiver therefor.

p0016The remote control transmitter (1) is provided with a key switch (3).

p0017For two erected in one bedroom beds two remote stations (1) are provided, at the non-operated push-button switches (3) by means of the keys (2) of a remote control transmitter (1) one of the beds and by means of the keys (2) of the other remote control transmitter (1 ) the other bed is adjustable.

p0018Both remote control transmitter (1) have an integrated component SAA 3004th On this, an oscillator (4) and a matrix array (5) are connected on the input side, acting on the keys (2). On the output side is the integrated component is an infrared transmitting device (6).

p0019The integrated component is provided with an address-control terminal (7) and address selection terminals (8, 9). If the address selection terminal (8) a signal to, then gives the sender -for operating the buttons (2) - from a pulse sequence, which controls the first recipient. If on the other hand at the address selection terminal (9) a signal, the transmitter emits a signal that -at a button is pressed (2) - controls the second receiver.

p0020Is located at both address selection terminals (8, 9) at the same time a signal, then the second receiver is driven, since the address selection terminal (9) has priority.

p0021The address control terminal (7) via a line (10), in which a diode (D1) is connected to the address selection terminal (8). In addition, the address control terminal (7) is connected to the address selection terminal (9) via an emitter-collector path (EK) of a switching transistor (T) and a further diode (D2).

p0022Paral lel to the emitter-collector path (EK) is a voltage divider consisting of a resistor (R) and the pushbutton (3) is switched. The tap of the voltage divider is situated at the base (B) of the transistor (T).

p0023At the first transmitter (1), which is associated with the first receiver in the control case, the push-button (3) lies between the base (B) and the collector (K) of the switching transistor (T) (see FIG. 2).

p0024At the second transmitter (1) which is assigned to the second receiver as a rule, the push-button (3) lies between the emitter (E) and the base (B) of the transistor (T) (see FIG. 3).

p0025The operation is essentially as follows:

p0026Both transmitters (1) normally open the key switch (3).

p0027If the key switch (3) open at the first station (1), the transistor (T) is blocked, so that through the line (10) a signal is applied only to the address selection terminal (8). So therefore the first transmitter (1) is assigned to the first recipient. If the push-button (3) closed at the first transmitter (1), the transistor (T) is conductive so that the signal from the address control terminal (7) abuts now on two address selection terminals (8, 9). Since the address selection terminal (9) is a priority, the first transmitter (1) is now assigned to the second receiver, so that, as long as the pushbutton (3) is closed, with corresponding actuation of a key (2), the functions of the second receiver controls.

p0028Once the key switch (3) is released, so open, the first station (1) is again ready to control the first receiver.

p0029At the second transmitter (1) is open, momentary-contact switch (3) of the transistor (T) conductive so that the signal from the address control terminal (7) on two address selection terminals (8, 9). Since the address selection terminal (9) is a priority, the second transmitter (1) controls the second receiver with a corresponding actuation of a key (2).

p0030If the push-button (3) of the second transmitter (1) is closed, locks the transistor (T), so that is now applied to the signal of the address control terminal (7) only at the address selection terminal (8). The second transmitter (1) is now ready to control the function of the first receiver. After releasing the push-button (3) the functions of the second receiver can be controlled again with the second transmitter (1).

p0031Because different, the first transmitter (1) and the second transmitter (1) only by the arrangement of the voltage divider (3, R), it is prepared as a plug unit in one polarity or the other polarity in the transmitter is either inserted.
