Definitions
- the invention relates to an electric motor drive, in particular for adjusting devices for furniture and the like, with at least one drive motor which can be controlled via a control unit by means of an operator part which has a plurality of actuating elements which can be optionally locked.
- the electromotive drive in question is preferably used for electromotive furniture drives, which are preferably used in the hospital area or in the care area. In these medical areas, special security is required so that the patients appearing as operators or the people in need of care are not endangered.
- the control unit is assigned to the operator part.
- the operator part is equipped with several actuating elements, for example eight push buttons, to trigger different functions.
- the signals to be fed into the control unit by the operator part can also be transmitted wirelessly via control cables. It must also be ensured that malfunctions are avoided, which can be triggered, for example, by damage to the control cable or by external signals.
- BESTATIGUNGSKOPIE Infeed into the block is decoded again.
- This solution means that little control effort is required, even though the functions are retained in full and the required safety requirements are fully met.
- the patients change frequently. Since, depending on the case of care or the illness, corresponding functions have to be blocked, changing blocked functions in the previously known operator parts is quite complex. This may even result in the nursing staff not being able to make such changes.
- the invention has for its object to design an electric motor drive of the type described in such a way that functions that can be triggered by actuating elements of the operator part for the operator or for the patient can be blocked in the simplest manner, and that the functions to be blocked in the simplest way can be changed. At the same time, it should be possible to carry out a self-check or self-diagnosis in order to avoid malfunctions.
- the operator part is equipped with a selection device such that only predetermined functions are available to the operator.
- the selection device is designed so that the operator part, preferably a hand switch, which can trigger several functions, is freely programmable.
- the design is such that there is sufficient free functional capacity to avoid malfunctions by means of automatic self-testing, self-monitoring or self-diagnosis.
- Such a device is of extremely simple construction and is designed in such a way that the selection of the functions available to the patient can be set in the simplest way. This makes it possible for the functions available to him to be changed during the treatment of a patient or when changing a patient.
- the activation element can lock and unlock all functions. In this way, the requirement of a relevant standard for a first-fault safety of the control unit can be met if the activation element is designed as a suitable, standard-compliant component in the respective application.
- the activation device can be a loose permanent magnet, a key switch or the like which can be inserted into the operating element. his. The activation device or the activation element is then only accessible to authorized persons, for example the nursing staff.
- the selection device enables functions of the operating device to be switched on or off as desired due to the free programmability.
- the activation element can be located on the back of the control panel. It can also e.g. B. a rotary switch or the like, which can only be actuated with a suitable tool, for example a key.
- a high level of security is achieved if the functional capacity of the selection device is designed in such a way that tasks for functional testing and self-diagnosis to avoid errors can be carried out at the same time.
- the selection device contains a microprocessor as the central component.
- control panel is equipped with a release actuating element such that a function can only be triggered when the release actuating element is actuated.
- the release actuation element could be a release button. A so-called two-hand operation then becomes necessary, since the release actuating element must always be actuated simultaneously to trigger a specific function.
- FIG. 1 is a block diagram of the operator part with the associated control part for the electric motor drive according to the invention.
- the operator part is identified by reference number 10.
- the associated control unit is identified by reference number 11.
- the operator part 10 contains a keyboard 12 with several operating elements or actuating elements 13 in the form of push buttons.
- the keyboard 12 is equipped with eight operating elements 13.
- the operator part is connected to the control unit 11 by a control cable 15, which in the exemplary embodiment shown contains eight wires.
- the signals sent when one of the operating elements 13 is actuated are fed into a module 16 of the control unit 11.
- the signals for triggering the desired function are transmitted to the electric motors of the electric motor drive. This is symbolically represented by the arrows 17.
- the operator part 10 is equipped with a selection device for free programming in order to block selected operating elements 13 for the patient. If a different selection is made or all control elements 13 are to be available, the control elements 13 which are initially locked can be unlocked by means of an activation element so that they can be used again. A new selection can then be made.
- Selection device can e.g. include a microprocessor as a central control module, the performance of which is also used to carry out simultaneous monitoring and testing tasks to avoid malfunctions.
