Description

  • The invention relates to a method for controlling the energy supply to one or more actuators designed as servomotors, a lying surface and / or Liegeflächenteilen - backrest, footboard, heart part or the like - a piece of furniture - couch, chair, bed, nursing bed, hospital bed - and rigid handlebar elements are associated with the lying surface and / or a base of the furniture in geared connection, wherein the power supply to the actuator in question is made by a single hand switch with actuating means, the signal-giving energy supply network for the actuators and the furniture is assigned, wherein the lying surface or its pivotally connected lying surface parts in height, if necessary in the room in different angular positions, adjustable by an associated actuator or by a plurality of actuators and can be locked in the respective position, with a plurality of arranged on the single hand control actuating means.
  • Furthermore, the invention relates to such furniture.
  • Finally, the invention relates to a controller for controlling the power supply to one or more actuators designed as servomotors for such furniture.
  • State of the art
  • From the published documents of the German utility model G 94 04 382.5 a furniture drive with one or more actuators and equipped with a triggering functions with actuators handset is already known in the selected or all actuators of the hand switch a respective function directly or delayed triggering additional switching device assigned. The additional switching device has a time switching element which delays the triggering of the respective function, the additional switching device comprising a block for time delay, a block for activating the function and a block for signal output. In the block for time delay, a block for signal detection and a block for pulse shaping is connected upstream and a block for function linking and forwarding of the signals downstream. The additional switching device includes a comparator, in which a certain sequence of actuated, free actuating elements can be stored, so that upon actuation of the additional switching device associated actuators the function can be triggered only in combination with the sequence. The auxiliary switching device includes a block for the signal recognition of the free actuators for the sequence, a block for forwarding the signals and a block for pulse shaping. Furthermore, the additional switching device includes a block for the signal recognition for the actuators of the special functions, a block for the input of the combination of the actuators, a block for the combination comparison and release, and a block for the function linking and forwarding. For this purpose, it is proposed in the case of the previously known furniture drive that the additional switching device includes a magnetically sensitive switch which can be actuated by a magnetic field. This magnetic field should be generated by a permanent magnet, which can be attached as a loose component from the outside to the housing of the hand-shaker. An alternative provides that the additional switching device includes an infrared or radio signals generating transmitter in the form of loose additional part and these signals receiving and processing the function triggering block in the form of a receiver. In addition, the additional switching device should include a reader for an insertable into the handset smart card.
  • If the additional switching device includes a comparator, a specific sequence of free actuating elements to be actuated should be storable in the latter, so that the function can only be triggered in combination with the sequence when the actuating elements assigned to the additional switching device are actuated. This solution has the advantage over the time delay that it should be extremely difficult for an unauthorized person to find out how the function is triggered. For the practical implementation proposes this known type that initially one of the additional switching device associated actuating elements is to be operated, and that then in the said sequence, the free actuators must be actuated.
  • Accordingly, the handset includes actuators associated with special functions that may only be triggered by authorized persons, such as nursing staff.
  • In an embodiment described in more detail, an actuator must be pressed until a time has elapsed after which the function is then triggered. Simultaneous pressing of actuators (buttons), therefore remains ineffective. When pressing the actuator, a switch is closed. From that moment on, the time delay runs. If the actuator is released in advance or pressed only briefly, no function is triggered. Also, a renewed pressing is ineffective, as to the actuators must be pressed.
  • The EP 1 948 108 B1 describes a bed that is adjustable in height and has several motors for height adjustment and adjustment of Liegeflächenrahmenteilen - backrest, foot part - has. This bed has a sensor device that works on the Hall effect.
  • A manual switch allows you to control a height position by authorized persons (nursing staff) who are not supposed to control the patient in bed. For this purpose, the authorized persons must press certain buttons on the handset at the same time to control this locked for the patient position (low position of the mattress frame).
  • task
  • Accordingly, it is an object of the present invention to provide a method for controlling a piece of furniture in accordance with the generic term in such a way that fast access to the control means is possible for the authorized persons, for example for the nursing staff in a hospital or nursing home, as well on such control means that allows the driving of the mattress frame in areas reserved for nursing staff only.
  • Furthermore, the invention has for its object to propose a structurally suitable furniture, in particular a nursing bed, hospital bed, intensive care bed, armchair or the like, which includes such a control.
  • Finally, the invention has for its object to provide for a furniture of the type presupposed an advantageous control of the power supply to the actuators designed as servomotors, which also allows the programmable control of only the nursing staff reserved areas of the bed with simple means.
  • Solution of the task regarding the procedure
  • This object is achieved by each of the independent claims 1 to 4 .
  • The procedure according to claim 1 makes it possible to control the lying surface and its parts by sequential actuation of an unlocking means and within a short period of seconds by operating at least one further actuating means on the maximum or below the minimum height of the lying surface or parts thereof, normally from Furniture user, for example, by a patient in a hospital bed or by a patient in a nursing bed, is controllable. This is above the patient-controllable altitude range lying maximum or below the minimum altitude range Area of the bed, can be controlled by the inventive method only by authorized persons, for example by the nursing staff.
  • A special feature is the sequential, ie successive operation of button-type actuating means on a single hand switch, namely an unlocking and then at least one further actuating means. Only if the very short period of time is respected, can the couch surface or its parts be controlled at altitudes that are below the height ranges normally accessible by the patient or above these height ranges. Inadvertent pressing of actuators on the handset, for example by pinching the handset under a pillow or the like, does not trigger the function reserved for authorized persons only. Because the unlocking means and at least one other actuating means is not sequentially-sequentially-actuated within a short period of time after the Entrlegelungsmittel has been released, that is no longer actuated, in particular is pressed, no function is triggered. Too long pressing or pressing only one actuating means, for example the unlocking means, does not make it possible to control the lying surface or its parts in height ranges reserved for authorized persons only.
  • A further advantage is that, in contrast to the prior art, no special additional switching devices, such as magnetic switches, which are to be attached to the outside of the handset, are required. Only if within the a very short period of time sequential actuation of the designated actuating means - unlocking and actuating means - done by the authorized person, the desired function is triggered, that is, the bed surface controlled with their parts in height ranges, not without a patient in a hospital or nursing bed are further accessible and could lead to damage to underlying objects or even injury if the bed surface is too low.
  • In the embodiment according to claim 2 , an actuating means is provided on the handset, for the storage of height settings of the lying surface, including the height ranges below and / or above the controllable by the bed user height areas and / or configurations of Liegeflächenteile - backrest, heart part, foot or The like - after actuation of the unlocking means is used. As a result, height ranges can be stored either by the manufacturer or else by authorized persons, which are above and / or below the usual height ranges located by the patient or the user of the furniture. In an emergency, retrieval of such altitude ranges by the authorized persons is given quickly.
  • In the method according to claim 3 , the lying area with its parts by authorized persons to a height relative to the floor between 30 and 50 cm, preferably between 20 and 35 cm, lower.
  • In the solution according to claim 4 , the bed surface with its Liegeflächenteilen of authorized persons over a maximum height between 70 and 85 cm, relative to the erection floor, go up.
  • Further inventive embodiments
  • Another inventive embodiment of the procedure according to the invention is described in claim 5 . In this case, after an actuation of the unlocking the signaling via another actuating means or further actuating means within a period of 0.5 to 2.5 seconds, preferably within one second after the unlocking means is no longer actuated.
  • Solution of the task concerning furniture
  • This object is solved by the features of claim 6 .
  • A piece of furniture of this kind can be a nursing bed, a hospital bed or an intensive care bed. Also, certain furniture can move like a chair against each other after appropriate angular adjustment of their mattress parts, so that then the resting, for example, in a bed person, this bed, for example, a hospital bed or a nursing bed, easier to leave or even use the bed if necessary. In the embodiment according to claim 7 , the handset on the user interface on a central, key-operated lock, which can unlock or block all actuators on the relevant handset functionally authorized only by authorized persons using a special key designed as a security key. Thus, for example, nursing staff, especially a nurse, can block the handset for all or certain actuation means. If, for example, the lock is locked by a key, the unlocking means is also locked, so that the unlocking means is unlocked again in a functional manner only after unlocking by means of a suitable key and after its actuation within the predetermined period of time allows the actuation of further actuating means, for example the Liegefläche low, below the normally controllable by the patient or the like height to the floor to drive or drive up in a height range, which is normally not controlled by the patient.
  • Solution of the task concerning the control
  • This object is achieved by each of claims 8 to 11 .
  • Each of these solutions enables quick and safe control without any additives on the single handset itself.
  • In claim 12, a preferred embodiment of the invention is described. In this a specific program is proposed to move the lying surface below the normally controllable by the patient height. By means of this program, for example, the lying surface can be lowered to a height, relative to the set-up floor, of at least 30 to 35 cm, preferably between 20 and 35 cm.

  • The reference numeral 39 denotes a rechargeable battery which serves as an emergency power generator, while 21 represents a power line for the electrical power supply of the actuators.
  • At 22, a bus bar is provided, to which a manual switch 23 or, if necessary, different manual switches can be connected.
  • The lying surface 2 can not exceed the dimension X ( Fig. 1 ) in height, so be raised, the measure Y referred to the Aufstellboden the Niedrigstbereich to which the bed surface 2 can be lowered, but only authorized persons by means of the manual switch 23 in the manner to be described while the dimension Z denotes a height range which lies above the area T to be controlled by the patient. Also, the height range Z can only be controlled by authorized persons by means of the manual switch 23.
  • In the case of the furniture 1 according to the invention, the manual switch 23 has various actuation means for this purpose, which consist of the Fig. 2 to 5 result. The respectively lying within the range C actuating means 24, 25 and 26, 27 relate to functions that are resting on the lying surface 2, for example, a person to be cared for without limitation in all embodiments Fig. 2 to 5 can be operated, for example, the lying surface within the area T ( Fig. 1 ) up and down and to lock in the respectively desired altitude within the range T via the actuators ( Fig. 1 ).
  • Also, the respective actuating means 28 in the handsets after Fig. 2 . 3 and 5 is to be operated by the patient. Above this, lighting is switched on and off, for example above the furniture or on the walls.
  • Furthermore, the actuating means 29 according to the manual switches Fig. 2 . 3 and 4 freely operated by the patient, as well as the actuating means 30 of the embodiment according to Fig. 2 ,
  • The red dot designated by the reference numeral 31 designates a key-operated security lock through which all functions of all the actuating means of the manual switch 23 can be switched on and off by an authorized person.
  • By the reference numeral 32 is in the manual switches after the Fig. 4 . 5 and 6 an unlocking means. Only after this unlocking means 32 has been actuated can, for example, the actuating means 33, 34, 35 in the Fig. 3 . 4 . 5 when the unlocking means 32 has been released and actuated within a predetermined time period of, for example, one second after releasing this unlocking means 32, the respective actuating means, for example 33 or 34 or 35. Is during the operation of one of these actuating means 33, 34, 35 actuates another actuation means, the actuation means triggered by the energy supply to the actuator in question is interrupted and the lying surface 2 or the lying surface part that was driven, blocked in the respective angular position and / or altitude.
  • If the unlocking means 32 is actuated, then released and then the actuating means 36 within a predetermined short period of time, for example one second, actuated, by further operations, for example, the actuating means 29, 33, 34, 36, 37 data stored permanently, and later retrieved later but later deleted if necessary, and the functions are reprogrammed. In this way, for example, height settings of the lying surface 2 or angular positions of lying surface parts, such as the backrest or the foot part, the middle part or the heart part in hospital or nursing beds, store.
  • The invention thus makes it possible to program functions exclusively for authorized persons, for example for nursing staff in hospitals, by means of a single manual switch. As a result, during extreme shutting down of the lying area 2 into the area Y ( Fig. 1 ) Damage to parts stored underneath the lying surface or even bruising of persons avoided. But the person can also enter the height range Z ( Fig. 1 ), which for the nursing staff in some cases facilitated access to the person to be cared for or treated.
  • Externally, the hand switch 23 does not need to be changed. In particular, no additional parts such as magnets or the like, which are to be infected somehow, as in the prior art required. Also, the authorized person need not carry any special parts with him to operate the unlocking means 32 and then an actuating means. Rather, only the unlocking element 32 is assigned to the manual switch, actuated by the operation of certain controls in rapid time sequence by an authorized person, in particular must be pressed in order to then supply the corresponding actuator or the actuators with electrical energy. The pictograms in the Fig. 2 to 6 illustrate the various positions to be taken.
  • For the actuators all possible drives, in particular linear drives, such as electric spindle drives, or the like are used, which are also normally used for the adjustment of lying surface frame and its parts such as backrest, heart part and footboard. Instead - as in Fig. 1 represents - in a hospital bed, the idea of the invention can also be used in other furniture, especially in articulated frame beds.
  • The features described in the claims and in the description and apparent from the drawing features, both individually and in any combination for the realization of the invention may be essential.
