The handheld remote control shown in the drawing is used to control electrical consumers, in particular for the operation and control of electrical drives for the adjustment of movable furniture parts.

The handheld remote control according to the invention can be used both as a cable handset and as a wireless handswitch. In 1 to 6 is the handheld remote control according to the invention as a cable handset 1 and in the 7 to 12 as a radio hand switch 2 shown.

Both handset 1 and 2 have a triangular in cross section housing 3 respectively. 4 on. The two housings and their inner lives are identical. Inside the case 3 respectively. 4 there is an in 11 and 12 illustrated circuit board 7 which serves as a carrier for a plurality of electronic components.

At the top of the case 3 respectively. 4 is a keypad 8th with a plurality of different buttons 9 arranged, which, when operated, various circuits on the circuit board 7 trigger.

Furthermore, inside is the case 3 respectively. 4 a transmitting device for the wireless transmission of control signals to the respective electrical load arranged. However, this is only according to the embodiment as a radio hand switch 7 to 12 used. For operation of the wireless handset 2 serve as in 11 is shown, three series-connected batteries 10 , which are designed as round rod batteries and have at one end their positive pole and at the other end their negative pole. To hold the three batteries 10 is inside the case 3 respectively. 4 an elongated battery compartment 11 provided with a correspondingly round cross-section. The batteries 10 are however only for the operation as a radio hand switch 2 needed. If the handheld remote control as a cable handset 1 to be used are the batteries 10 not mandatory. It even needs at least one of the batteries 10 from the battery compartment 11 to be removed, in particular, from 4 to 6 shows the end cap 5 at the correspondingly formed end of the housing 3 to be able to fasten.

The end cover 5 is with one end of a cable 12 connected, which has a strain relief 13 , which also serves as kink protection, firmly on the end cap 5 sitting. The cable end is electrically connected to the housing 3 directed inside of the cover 5 arranged cable plug connection 14 connected, which may be formed for example as a mini-USB. In the assembled state of the lid 5 is the cable connector 14 automatically with the circuit board 7 connected.

The positive connection between the end cover 5 and the corresponding end of the housing 3 is designed as a plug-in rotary connection or bayonet connection. For this purpose is on the inside of the end cover 5 one from the outside of the end cover 5 actuatable, in both directions rotatable cylinder 15 arranged, in particular from the 5 and 6 shows exactly flush in the round battery compartment 11 fits if at least one of the batteries 10 from the battery compartment 11 is taken.

At the outer circumference of the cylinder 15 are on diametrically opposite sides projections 16 provided, which form a crossbar. In the wall of the battery compartment 11 are on opposite sides longitudinal grooves 17 for receiving the projections 16 or the cross bar arranged. At the end of the longitudinal grooves 17 they open in Umfangsnuten 18 in which the projections forming the crossbar 16 with completely attached end cover 5 are rotatable. The length of the circumferential grooves 18 is limited, so that the cylinder rotation in the final mounting position of the end cover 5 is limited. In the 4 to 6 is the open position of the cylinder 15 illustrated, in which the cross bar occupies a horizontal position. In this position, the cylinder 15 in the battery compartment 11 inserted, wherein the transverse bolt forming projections 16 in the longitudinal grooves 17 intervention.

When the end cap 5 at the front 21 of the housing 3 is present, the cylinder has 15 reached its lowest position in which the projections 16 with the circumferential grooves 18 aligned. When this position is reached, the cylinder becomes 15 turned into the locking position. For this purpose, the cylinder 15 on its outside a transverse slot 19 so that it can be easily turned using a screwdriver or a coin.

In the locked position, the cable plug connection engages 14 in a connection socket provided on the housing 20 one that makes electrical contact with the circuit board 7 manufactures.

At the respective end cap 5 respectively. 6 facing end face of the housing 3 respectively. 4 are also three receiving openings 22 and 23 intended. The two upper receiving openings 22 have a slit-like shape while the lower receiving opening 23 has a larger rectangular profile. From the lower receiving opening 23 goes to the bottom of the case 3 respectively. 4 running slot 24 whose function will be described later.

At the in 1 to 6 illustrated embodiment in which the handheld remote control as a cable handset 1 is formed, serve the three receiving openings 22 . 23 for additional centering of the end cover 5 on the housing 3 , For this purpose are on the inside of the end cover 5 appropriate fittings 25 arranged the shape of the receiving openings 22 and 23 are precisely adapted and a good additional positioning and anti-twist device for the end cover 5 form.

In the 7 to 12 is the handheld remote control according to the invention as a remote control 2 educated.

As in particular from the 7 to 9 shows, is the end cap 6 completely smooth on its outside. The battery compartment 11 is how in 11 illustrated with three rod-shaped batteries 10 or batteries filled. The positive pole 26 , in the drawing right arranged battery 10 is against the end cap 6 directed.

Like from the 10 to 12 indicates the end cap 6 at his the battery compartment 11 facing inside an electrically conductive metal tongue 27 on, for the electrical connection between the batteries 10 and the circuit board 7 serves.

As in particular from the enlarged view in 12 shows that the plus pole lies 26 the right battery tight against the middle portion of the tongue 27 at. The leading end of the tongue 27 touched with firmly mounted end cover 6 a connected to the circuit board electrical contact part 28 so that it creates a direct contact between the batteries 10 and the circuit board 7 is closed, whereby also provided in the housing, unspecified transmission device for wireless transmission of the control signals is included in the circuit, so that upon actuation of the corresponding keys 9 an actuation and a drive of the corresponding electrical consumers can be effected.

For fixing the end cover 5 at the front 21 of the housing 3 respectively. 4 are on the inside of the end cover 3 Provided fasteners, namely two upper locking hooks 31 and a lower spring hook 29 , The two upper snap hooks engage in the in 9 slot-shaped receiving openings shown 22 while the lower spring hook 29 in the lower receiving opening 23 locks. At the lower spring hook 29 is on the underside of a down-facing bridge 30 provided in the mounting state in the of the receiving opening 23 down-facing slot 24 intervenes. As already described above, the slot is 24 from the bottom of the case 4 accessible, so the spring hook 29 when the jetty 30 is pushed up, unlocked and the end cap 6 releases. The height of the bridge 30 can be designed so that this bridge in the attached state of the end cover 6 flush with the bottom of the case 4 concludes. The jetty 30 but then with the help of the tip of a screwdriver or a coin up to the unlocked position of the spring hook 29 be pressed. In this way is also a release of the end cover 6 easily possible by an untrained person easily.

In that respect, the two end covers 5 and 6 be replaced arbitrarily and without much effort by non-professionals to re-implement a cable handset in a wireless handset and vice versa.

If a cable break should occur, then the handheld remote does not need to be repaired, but the consumer simply procures a new end cover with the integrated cable, and connects it to the housing itself.

The number of electrical contacts of the cable connector 14 and the number of cores corresponding to the connecting cable can be advantageously reduced to a minimum. This increases the ease of use for the user when choosing a cable handset 1 because this makes it possible to use a very thin and very flexibly bendable and light cable. The cable plug connection 14 has contacts for transmitting the power supply and contacts for the transmission of control commands, wherein the control commands are formed in one embodiment as a data form.

Furthermore, the cable handset points 1 or the wireless handset 2 a microcontroller or a microprocessor having signal terminals as signal inputs and as signal outputs. The contacts of the buttons 9 For example, are conductively connected to signal inputs. Some contacts of the cable connector 14 are connected to signal terminals.

Furthermore, the radio unit for wireless transmission of radio signals is electrically connected to signal terminals. Predetermined signal connections of the microcontroller or of the microprocessor are designed to be controllable by means of the software program used there and are in electrical connection with the radio unit. The software program alternatively includes a plurality of individual programs or, alternatively, several program sections. Signal terminals which are connected to the radio unit can supply a supply voltage for the radio unit. In a further embodiment, they can carry data or radio commands or control commands for controlling electrical consumers, in particular drives for adjusting movable furniture parts, for generating corresponding radio commands.

Conversely, terminals of the radio unit are in operative connection with signal terminals of the microcontroller or with other switch terminals. In one embodiment, these connections of the radio unit are designed as signal connections. In a further embodiment, these connections are designed as supply connections of the radio unit.

It is now desirable that the wireless handswitch 2 also as a cable handset 1 and vice versa can be used. This increases the flexibility of the final product and is a requirement of the end user. As mentioned in more detail, remains in any case, the inner workings of the cable switch 1 and the wireless handset 2 identical. It is intended that when using the cable switch 1 the radio unit is switched off or deactivated. This can be done in different ways or according to different methods.

In a first embodiment, the microcontroller has a software program which checks the application of a battery voltage to predetermined signal connections. For this purpose, at least one battery terminal contact with the associated signal terminal is electrically connected. If a battery voltage potential can be detected, the signal is changed at another signal terminal of the microcontroller, for example a voltage signal is output which is connected to a supply terminal of the radio unit and thus sets the radio unit into operation. Alternatively, upon detection of a battery voltage potential, other signal terminals are supplied with signals which are formed as data or control signals, abut the signal terminals of the radio unit and are formed corresponding to the radio signals of the wireless radio transmission path.

In a further embodiment, the electrical connection of the manual switch 1 . 2 two circuits on. Each circuit has a diode at a common start or end path. The first circuit is designed as a radio circuit and includes the radio unit. The second circuit is the key circuit with the microcontroller. One port of a battery is connected to both diodes.

An energy connection of the cable connector 14 is only with the circuit of the buttons 9 connected. The function is now as follows: When starting up the wireless handset 2 Both circuits are put into operation and the radio unit can generate and transmit radio signals. When commissioning the cable handset 1 is the diode that is inserted into the radio circuit, designed as a blocking diode or functions as a blocking diode, so that no commissioning of the radio unit takes place.

In a further embodiment has a cover 5 respectively. 6 a number of actuators, which with switchable contacts of the manual switch 1 respectively. 2 keep in touch. Will be a cover 5 respectively. 6 removed or attached or will be another end cover 5 respectively. 6 set, so there is a switching change of the switchable contacts by being actuated or alternatively not operated. In any case, the switchable contacts are conductively connected to signal terminals or alternatively to supply terminals of the radio unit or of the microcontroller.

According to a very simple embodiment, the end cover is formed without a cable connection 6 an approach that when putting the end cover 6 to the housing 3 respectively. 4 a trained as NO contact pushbutton is actuated, which is connected to a supply terminal of the radio unit and closes the circuit with battery and radio unit when actuated. Alternatively, the contact of the push-button switch, whether it is designed as normally closed or normally open, is connected to signal terminals of the microcontroller, analogous to the description above, a software program interrogating these signal terminals and, as described above. has an influence on the data transfer or on the supply voltage to the radio unit.

Individual features of the invention are, although within certain limits, combined with each other. It is essential, however, that in the execution of the manual switch as a cable handset 1 no radio signals are transmitted, which means a reduction of electromagnetic waves in the environment and that in the execution of the hand switch as a wireless hand switch 2 an activation or supply of the radio unit takes place or that in the execution of the manual switch as a radio-hand switch 2 this is designed for the transmission of wireless radio commands.

When the hand-held remote control according to the invention is to be converted from radio to cable operation, the end cover becomes 6 or adapter from the housing 3 respectively. 4 removed, and it will be the one with the cable 12 provided end cover 5 on the case 3 respectively. 4 placed. In this state, therefore, no wireless transmission of signals should take place.
