Definitions

  • the invention relates to an electromotive furniture drive with at least an actuator and at least one control unit, which on the input side equipped with a connection for a control line transmitting the control signals and in which the control signals from one or more operating devices can be triggered via control cables.
  • the electromotive furniture drive in question can, for. B. a linear actuator be equipped with one or more output members, which with adjusting furniture parts are coupled. Among other things, they are also used for nursing and hospital beds.
  • the furniture drive is a single drive with a Servomotor or a double drive with two servomotors.
  • the control device is a hand switch that is used to trigger the various functions a corresponding number of push buttons.
  • the second manual switch for the Patient locked because functions can be triggered with this hand switch which are reserved exclusively for nursing staff.
  • connection of a second control device to a furniture drive requires always an extension or change of the control board of the control unit and possibly also an enlargement or change of the housing of the Control unit and possibly also a change or enlargement of the housing for the furniture drive.
  • lock box it is also known to use a lock box to perform certain functions of the To lock and / or release the patient's intended hand switch.
  • the lock box is between the control unit of the furniture drive and the operating device interposed for the patient.
  • the lock box is in the Range of the patient so that they can unlock the locked functions themselves can. Since the nursing staff do not have a dedicated operating device existing control elements can no longer be connected become.
  • the invention has for its object an electric motor furniture drive the type described in more detail at the outset so that it is structurally identical or different operating devices can be equipped, whereby only one control line is connected to the control unit, and that none structural changes to the furniture drive are necessary.
  • connection unit with one of the number of Control cable corresponding number of inputs on the input side for the Control cable solved, which also has an output connection for the only control line is equipped such that the same functions of the servomotors triggering signals of all hand switches can be transmitted to the control line are.
  • connection unit can on the furniture in question at any and more suitable Position, because the control line leading to the control unit is a has the appropriate length.
  • the connection unit does not contain a locking device because such and / or further operating devices of the connection unit are functional can be assigned. Such a locking device or other operating devices can be arranged in places inaccessible to the patient become.
  • connection unit in the manner of a
  • the modular system consists of several components and is designed as an expansion unit is. This allows it to be designed according to the respective requirements become.
  • the individual modules can be used in the same way as a parallel connection or can also be expanded like a series connection.
  • connection unit has a locking device is assigned such that with the actuating elements of the operating device connected wires of the control cable for the transmission of signals can be locked or unlocked. It is then possible that certain functions no longer when operating the operating elements of the operating device can be triggered.
  • the means of the locking device functions that can be excluded for the operating device accessible to the patient are lockable.
  • connection unit has a the foot operated operating device is assigned such that all by means of Components driven by motors can be moved into a predetermined position. For example can then in case of recurring bed cleaning all drives of the bed are switched on by pressing a single button, the drives are then moved into the position that is favorable for cleaning.
  • the drives to be operated can vary depending on the construction of the bed have different directions of movement and also different in number his.
  • connection unit Assign drives with different functions to the respective foot switch.
  • the bed manufacturer carries out this assignment before delivery or at installation once.
  • function of additional limit switches can also be easily assigned, for example to determine the end positions, without having to change the drive control.
  • the exemplary embodiment shown in FIG. 1 has two hand switches 1 and 2 equipped, the control cables 3 and 4 open into a connection unit 5.
  • a more detailed lock box 6 is connected to the connection unit 5, so that the connection unit 5 is equipped with three connections.
  • the arrow is intended to indicate that when one of the hand switches 1 or 2 triggered signals in the control unit of the electromotive, not shown Furniture drive can be fed.
  • connection unit 5 could also more than two hand switches can be connected.
  • the connection unit 5 would be then equipped with a corresponding number of connections for the control cable.
  • the two hand switches 1 and 2 identical in construction, so that either hand switch 1 or 2 is selected for the patient can be. A subsequent exchange must be prevented, however, because in various functions for the patient can be blocked as described in more detail can.
  • the hand switch intended for nursing staff 1 or 2 more functions has as the hand switch for the patient.
  • the lock box can be equipped with one or more rotary switches to block functions for the patient by appropriate positions of the switch. It is then immediately visible which functions are blocked. Besides, can they contain additional function keys that cannot be locked and are only available to nursing staff, for example in configuration: Patient operation 1 / lock box 6 / foot switch 7.
  • a foot switch 7 which is operated exclusively by nursing staff shall be.
  • the hand switch 2 omitted or the foot switch 7 could be connected in parallel with it.
  • connection unit 5 is designed and exists in the manner of a modular system from several modules, so that by adding additional modules an extension is possible.
  • connection unit 5th is reserved for the lock box 6.
  • a circuit 9 which will be explained in more detail, the ones to be blocked in each case Lines of all operating connections of the connection unit 5 are activated or locked.
  • the arrangement can be designed so that for the nursing staff provided hand switches 1 or 2 cannot be locked using the lock box can.
  • the hand switch 2 is for the nursing staff been replaced by the foot switch 7.
  • Reference number 10 is the connection for the foot switch 7, by reference number 11 the connection for the lock box 6 and by the reference numeral 12 the connection for marked the patient's hand switch 1.
  • connection unit 5 is equipped with three relays 13, 14, 15 and three freewheeling diodes 16, 17, 18 equipped. It also contains decoupling diodes 19. Of the aforementioned Components, the wires are brought together to form a common connection 20, through which the connection to the control unit 8 is established.
  • Each relay 13, 14, 15 is a specific function group for example, the back drive, the foot section drive and a height adjustment assigned.
  • a manual control button S1-S6 is the connection of the associated relay coil via the associated decoupling diodes 19 placed on the plus potential.
  • a relay 13, 14, 15 only switches the corresponding contact set when the connection of the relay coil via the associated switch S7, S8 or S9 Lock box 6 is placed at the negative potential. Only then will it trigger the function Signal forwarded to the drive, not shown.
  • relays are safety-related compared to other versions cheaper because there is a real electrical isolation.
  • a larger, Standard-related area of application reached.
  • the freewheeling diodes 16, 17, 18 serve when switching off the relay coils to extinguish the spark and thus to protect the Pushbuttons S1-S6.
  • the lines of the foot switch 7 can via coupling diodes 21, 22 by means of miniature switches 23 are assigned to the respective function-triggering lines.
  • the interconnection takes place before the make contacts the blocking relay, which according to the circuit diagram between the connection 12 for the Hand switch 1 and the make contact connections. This is the locking function effective for the foot switch 7.
