Definitions
- the invention relates to an electromotive adjustment arrangement for furniture that is equipped with at least one drive motor, and in that by means of a manual control device Signals into a control unit containing a motor relay arrangement are feedable.
- the electric motor adjustment arrangement in question is in known many designs. The respective version depends on the type of the furniture and according to the adjustment path. Usually the adjustment arrangements as single drives with one drive motor or as double drives with two Drive motors equipped.
- the furniture equipped with it is not only used in the domestic area but also used in the hospital or nursing area. Particularly in the medical fields, special guarantees are required thus the patients appearing as operators or the people in need of care not be endangered.
- the manual control device is usually a manual switch, which is equipped with several push buttons to perform the different functions trigger. Those to be fed into the control unit from the manual control device Signals can be transmitted via control cables or wirelessly.
- the manual control device equipped with a selection device that is designed so that for the Operator only selected functions are available.
- This selection device is so designed that the hand control device is freely programmable. Furthermore, it is so designed to have a sufficient free working capacity to avoid malfunctions by means of an automatic self-check, self-monitoring or self-diagnosis is available. It also has the so-called first fail safety be guaranteed, that is, if an error occurs, for example a faulty motor relay, this error must be displayed.
- Each Drive motors are normally assigned to two relays, i.e. each relay switches the motor on and off for a certain direction of rotation. These relays are analogous to be regarded as a wearing part, so that it can happen that the relay contacts glue accordingly, so that the function is no longer guaranteed, that is, that the motor can no longer be switched on or off.
- the invention has for its object an electromotive adjustment arrangement of the type described in more detail at the beginning so that the control unit is opposite the previously described structurally simpler and therefore less expensive becomes.
- the task is solved by the control unit with a release relay is equipped in such a way that it corresponds to the respective relay of the motor relay arrangement supplied current is applied, and that the release relay a function monitoring module assigned.
- control unit becomes simple when the release relay of the motor relay arrangement is connected upstream.
- the control unit is also equipped with a diode gate equipped, which is designed and integrated in terms of circuitry is that the release relay always when an operating element of the manual control device is actuated switched on or flooded with electricity.
- This diode gate expediently consists of at least two diodes per motor.
- the function monitoring module is designed so that at least the contacts and the drive of the release relay are monitored.
- the circuit diagram shown in FIG. 1 is for a double drive, that is to say for one Electromotive adjustment arrangement designed with two drive motors 10 and 11.
- the manual control device contains four switches 12, 13, 14, 15, which are preferably designed as push buttons.
- the circuit arrangement has two relays 16, 17 and two further relays 18, 19 for motor 10 for the motor 11.
- the motors are preferred with a safety DC voltage operated.
- the circuit arrangement also contains an enable relay 22, which is switched so that the contacts are closed when one of the relays 16 to 19 is switched.
- the release relay 22 is functional with a diode gate 20 linked, which in the case of two motors 10, 11 consists of four diodes.
- the release relay 22 is associated with a monitoring module 21, which at least the coil and monitors the contacts of the enable relay 22. Once the functionality of the Release relay 22 is no longer present, an indication is given, which is preferably acoustic or can be done optically. This display could be in a preferred version done in the hand control.
- the monitoring module 21 can via a Control line connected to the enable relay 19, although wireless monitoring is preferred.
- the invention is not restricted to the exemplary embodiment shown.
- Essential is that the circuit arrangement contains an enable relay 22 which switches as soon as a motor relay 16 to 19 picks up by operating a switch 12 to 15, and that the functionality of the enable relay through the monitoring module 21 is checked.
