Definitions

  • the invention relates to a control device for the air tubes of a support device for the human body, such as a couch, mattress or seat, according to the preamble of the main claim.
  • At least two inflatable air tubes lie one above the other in a mattress-like molded body, which form individual, horizontally oriented groups, the groups being individually controllable and, moreover, the tubes lying one above the other being able to be controlled independently of one another.
  • Each of the fields thus formed is connected to a pump, regulating and control system.
  • a pump supplies pressure and vacuum for the individual fields and the control device has motor-driven distributor valves or solenoid valves which are switched by a camshaft. These valves cyclically connect the rows with the pressure sources and vacuum sources, so that each row is sequentially inflated, partially deflated by air escaping through the perforation of the air hoses and by Ver bond with the vacuum source is actively emptied.
  • Such an arrangement aims to ensure that the user of the couch is carried by the air tubes of the group which is inflated, while the parts of his body which lie above the deflated and therefore collapsed air tubes are not subjected to pressure from the mattress, so that the blood can circulate more freely in these parts of the body.
  • This known arrangement is therefore intended in particular exclusively for medical storage purposes.
  • DE-A-32 46 221 proposes a slatted frame for normal use, which is equipped with air hoses, each of which is equipped with valve means for inflating, corresponding control devices being provided, but which are not explained in more detail.
  • a backrest for a motor vehicle which consists of several individual air hoses.
  • a pump is provided and a pressure chamber is formed in a control unit, which is connected to the pump, connection lines being assigned to each individual air hose, connecting the respective air hose to the pressure chamber, and switching valves being assigned to each connection line.
  • the switching valves are located in a bypass line and open in a connecting line between the connecting hose and the pressure chamber.
  • the individual connection lines connect to the pressure chamber via a check valve.
  • the invention has for its object to improve the generic device in such a way that it is possible to fill each individual air hose or group of air hoses with air regardless of the degree of filling of other hoses or groups of hoses and pressure control between the switching valves only by actuating the switching valves bring connected hoses.
  • the inventor strikes a control unit, to which the compressed air pump is connected on the one hand and which has a central pressure chamber, to which the switching valves are connected, the individual connecting lines for the respective air hose in turn being connected to the individual switching valves.
  • a compressed air reservoir is created through the pressure chamber, with which the connecting line assigned to the air hose is connected via the switching valve.
  • a manually operated drain valve connects to the central pressure chamber.
  • only one air hose By actuating only one switching valve, only one air hose can be regulated with regard to its pressure strength independently of the other air hoses, and by operating several switching valves or all switching valves, all air hoses or all air hose groups can have a common pressure or the pressure between the hoses of this air hose group can equalize.
  • DE-U-71 14 046 also deals with a filling and emptying device for so-called pressure change mattresses.
  • an overpressure chamber that is connected to all hoses via lines, separate from it to provide a vacuum chamber that is connected to all hoses via lines and that a pump should connect to the overpressure chamber, while a suction pump connects to the vacuum chamber.
  • FIG. 1 designates a control device which, as the diagram in FIG. 1 shows, is of relatively small construction and is therefore handy, so that even a layperson can operate it lying in bed without difficulty.
  • Fig. 1 are those at the top of the Control unit 1 arranged switching valves 2 recognizable.
  • 3 shows a manually operable drain valve and 4 shows a connection for a connecting line 5 shown in FIG. 2, a check valve 6 being provided between the control unit 1 and the connecting line 5, as illustrated in FIG.
  • the connecting line 5 leads from the connection 4 to a preferably electrically operated pump 7, wherein a hand bellows 8 can be connected into the connecting line 5, by means of which a slight readjustment is possible without starting up the electric pump.
  • a pressure chamber 9 is provided, which forms an air reservoir and on the top of which the switching valves 2 open.
  • Each switching valve has a connecting line 10, these connecting lines leading to an air hose 11 or to an air hose group.
  • the switching valves 2 are designed as seat valves and have an actuating head 12 which carries a plunger 14 and is so pressurized via a compression spring 15 that a sealing cone 16 is pressed against a valve seat with the interposition of a corresponding seal , which is designed as a connecting line 17.
  • the individual connecting lines 10 open into this connecting line and this opening is shown at 18 in FIG. 3. It can be seen that when the actuating head 12 is depressed, the valve cone 16 is lifted off, so that the associated connecting line 10 is now connected to the pressure chamber 9 is possible. This results in a pressure equalization between the internal pressure in the air hose 11 and the internal pressure of the pressure chamber 9.
  • a regulation of the pressure is also possible in that when the switching valves 2 are closed, all the air hoses 11 have a relatively high pressure, then the pressure in the pressure chamber 9 is reduced by actuating the drain valve 3 and now a pressure equalization between them is opened by opening individual or several switching valves Switching valves associated with air hoses can be done.
  • a collecting line 19 is shown in the drawing, in which the individual connecting lines 10 are combined at least in the area of the control device, so as to have as little interference as possible when the control device is actuated.
