Definitions

  • the invention relates to a device for opening a safety sliding door, in particular fire door or bulkhead, which can be closed and opened by means of a hydraulic or pneumatic drive device, with an actuating device provided adjacent to the sliding door, by means of which the drive device can be activated to move the sliding door is.
  • the fire doors and bulkheads described above can be actuated by central activation of the drive doors or each of the bulkhead has a separate actuating device with which opening and, if necessary, closing can be carried out.
  • This actuating device is in the form of a valve which can be actuated by means of a hand lever, and is usually fastened adjacent to that edge of the door frame on this or the wall adjacent thereto, with which the closing edge of the sliding door comes into engagement in the closed position.
  • the safety bar activates a release valve, as a result of which the pressure present there is fed via a pressure line to a reversing valve which is used to drive the actuator device-forming piston-cylinder arrangement is connected and which is then reversed so that the pressure acting previously in the closing direction on the piston of the piston-cylinder arrangement reaches the opposite surface of the piston and thereby causes an opening movement of the sliding door.
  • a device for opening a safety sliding door in particular fire door or bulkhead, which can be opened and, if necessary, also closed by means of a hydraulic or pneumatic drive device, is provided with an actuating device provided adjacent to the sliding door, through which the drive device for actuating the Sliding door can be activated, and with a safety bar that is limitedly movable in the region of the closing edge of the sliding door between a rest position and a release position, the activated a trigger valve in the trigger position, which causes an opening movement of the sliding door in this position, designed according to the invention in such a way that a pneumatic piston-cylinder arrangement is provided, the piston rod of which is fastened to the sliding door and in which a pressure chamber is formed which is connected to a is acted upon by the pressure in it in the closed position check valve with its end surface facing the interior of the cylinder, and that the release valve in the release position establishes a pressure connection between the pressure chamber and the actuating device and moves it into the position for opening the sliding door
  • the trigger valve is therefore not connected to a pressure source for working fluid in the form of a pump, but the pressure required for an emergency opening is built up in that the pressure which arises when the sliding door is closed and thus when the piston is retracted into the cylinder via the Check valve is passed into the pressure chamber, so that a sufficient pressure is built up in the pressure chamber after the closing of the sliding door to activate the actuating device in an emergency by means of this pressure.
  • the trigger valve is thus not connected to an external pressure source, for example that which also operates the drive device, but is acted upon by a pressure which is built up completely independently of this external pressure source during the closing movement of the sliding door.
  • the release valve is advantageously connected on the one hand to the pressure chamber and on the other hand by the piston rod to an area between the piston rod and the cylinder, the advantage being that no flexible lines are required between the door frame and the sliding door, but instead the working fluid is guided from the piston rod firmly connected to the sliding door via the stationary cylinder.
  • a float valve can be provided between the cylinder and the actuating device, which is moved into its working position by water and in this interrupts the connection to the actuating device.
  • the effect of the device according to the invention is rendered ineffective when water enters, ie the device according to the invention can Do not activate the actuating device for the hydraulic or pneumatic drive device causing the opening process in order to open the sliding door, so that the closing movement of the sliding door is continued from the rest position into the release position even when the safety bar is moved.
  • the interior of the cylinder can be connected via a connection opening into its bottom surface and a check valve acted upon by pressure in the interior in the closing direction be connected to the ambient air. Using this check valve, working fluid can enter the cylinder when the piston moves, thus preventing the creation of a vacuum.
  • the interior of the cylinder can be connected to the ambient air via a connection opening into its bottom surface and a pressure relief valve.
  • an additional recess for the safety bar can be provided in the surface of the door frame or the door frame that comes into engagement with the closing edge of the sliding door, so that the safety bar does not move from its rest position into the closed position Release position moves and thereby the sliding door is opened again.
  • the safety bar can be set between a standby position in which it lies in front of the closing edge and a closing position in which it is outside the area of the closing edge, parallel to the closing edge and be pivotally supported at a distance from this extending axis.
  • the security bar is fastened to a holder which is articulated at a distance from the closing edge on a main surface of the sliding door and has a pivoting section which is provided on the side of the pivot axis facing away from the security bar, and that in the In the closed position, the area of the door frame coming into engagement with the closing edge is provided with at least one projection which comes into pivoting engagement with the pivoting section before reaching the closed position of the sliding door.
  • the safety bar can be attached to the sliding door or the holder on a swivel bracket which holds the safety bar in the rest position by gravity and which, when the safety bar is moved into the release position, can be moved laterally in an arc and move upward. Spring arrangements are thereby avoided.
  • the sliding door 1 or 101 shown in the figures is, for example, a bulkhead on a ship, which can be opened and closed in the usual way by means of a hydraulic drive device.
  • the hydraulic drive device is not shown in the present case.
  • details of the door frame or the door frame and the guidance of the sliding door are missing in the illustration, since these details are also known.
  • the usual structure includes, in addition to the sliding door 1, an actuating device which is fastened to a carrier plate 27, the carrier plate being fixed in a stationary manner adjacent to the edge of the door frame or the door frame which comes into engagement with its closing edge in the closed position.
  • a hydraulic valve 28, which can be actuated manually by means of a handle lever, is pivotably attached to this carrier plate 27 and is coupled to a working cylinder 29 which is also fixed in a stationary manner.
  • the handle lever of the hydraulic valve 28 is normally held in a neutral position by spring force. By pivoting the handle lever upward, the hydraulic valve 28 is switched over so that it acts on the drive device, not shown, for the sliding door 1 in such a way that it is closed. If the handle lever is pivoted downwards, the sliding door 1 is opened accordingly.
  • the piston rod 6 of a piston-cylinder arrangement is fastened to the sliding door 1 by means of tabs 2 and via a fork joint.
  • the piston rod 6 carries at its rear end a control head 5 with a function to be described valve 42 and with connections for pressure lines 11 and 12.
  • the piston rod 6 extends into a via mounting holes 10 ( Figure 2) stationary on one of the door frame or
  • the cylinder 8 adjacent to the door frame is attached to a cylinder 8 which carries a cylinder head 7 on its right end in FIGS.
  • the line 11 connected to the control head 5 leads to an actuating valve 13 which is fastened to the sliding door 1 near the closing edge thereof.
  • the line 12 leads from the actuating valve 13 to the control head 5 via a throttle device 15 which is also fastened to the sliding door 1.
  • a safety strip 16 is attached, which extends from the lower edge of the sliding door 1 upwards to just below the upper edge of the sliding door 1 (FIG. 2).
  • This safety strip is held by joints by its own weight in a rest position in a manner to be described, in which position it is shifted to the left from the closing edge in the figures.
  • the safety bar 16 can be shifted to the right in its release position in the direction of the closing edge of the sliding door 1, that is to say in FIGS. 1 and 2, so that it releases the trigger plunger 14 of the actuating valve 13 which is adjacent to it in FIGS 2 moved to the right, thus activating the actuating valve 13.
  • the line 11 is connected to a line 21 extending axially parallel through the piston rod 6, which ends in a pressure chamber 34 formed in the piston rod 6.
  • the pressure chamber 34 is connected to the interior 41 of the cylinder 8 via a bore 35 which extends through the bottom of the piston formed on the piston rod 6.
  • the bore 35 is closed by a check valve 37, which is acted upon by an overpressure in the pressure chamber 34 in the closing direction.
  • the line 12 is connected via the valve 42 to the line 22, which runs parallel to the axis in the piston rod 6 and which extends through the pressure chamber 34 and through an obliquely radially outwardly extending bore 23 into the annular space 24, which extends between the piston rod 6 and cylinder 8 is formed and which is sealed against the interior 41 of the cylinder 8 by the ring seal 36 seated on the piston and by ring seals in the cylinder head 7.
  • This annular space 24 leads to a Cylinder head 7 provided, radially extending bore 25 to which a line 26 is connected.
  • This line runs via a float valve 30, 31 to be described, to the working cylinder 29.
  • a line 32 is also connected to line 26, which leads to a safety valve 33, as described in EP-OS 0 139 131.
  • a bore 38 is provided in the bottom wall of the cylinder 8, to which a check valve 39 is connected.
  • This check valve opens at negative pressure in the interior 41 and connects it to the ambient air.
  • an overpressure valve 40 is connected to the bore 38 and opens at a predetermined overpressure in the interior 41 and thus limits this overpressure.
  • the sliding door 1 In normal operation, the sliding door 1 is open. However, it can be closed centrally or, as already mentioned above, on site by pivoting the handle lever of the hydraulic valve 28 upwards, since the drive device (not shown) thereby exerts a closing force on the sliding door 1.
  • the piston and the piston rod 6 are pushed into the cylinder 8.
  • an overpressure arises in the interior 41, by means of which the check valve 37 is opened and thus practically the same pressure is built up in the pressure chamber 34. If the pressure built up exceeds a predetermined value, the pressure relief valve 40 opens.
  • the release valve 13 returns to its inactive position.
  • the immediate venting and thus switching back of the valve 42 is delayed by the throttle device 15 inserted in the line 12, so that initially the connection from the pressure chamber 34 via the line 43 to the line 26 is maintained and the opening process is thus continued.
  • the valve 42 switch back and interrupt the connection between the line 43 and the line 26.
  • the working cylinder 29 returns to its neutral position given by a spring arrangement, and the hydraulic valve 28 also enters its neutral position. If the drive device is still acted upon by a central closing command at this time, the closing process of the sliding door 1 begins again.
  • the float 30 of the float valve 30, 31 is raised and it switches the associated valve 31 into a position in which it the line 26 closes and the working cylinder 29 is vented. If the safety bar 16 is then moved from its rest position into the release position, the process described above takes place, in which the valve 42 connects the pressure chamber 34 to the line 26 via the line 43. In this case, however, this pressure cannot act on the working cylinder 29 because of the blocking by the valve 31, so that the sliding door 1 is moved from the drive device into the closed position despite the movement of the safety bar 16 into the release position.
  • the closing process cannot be interrupted even if, for example, the safety valve 33 has responded to a fire and the line 26 is vented via the line 32.
  • the edge of the door frame or the door frame 50 which comes into engagement with the closing edge of the sliding door 1 can be designed such that it has a receiving recess 51 into which the closing edge and the region of the sliding door 1 adjacent to it enters, when the sliding door 1 is closed.
  • a receiving recess 51 into which the closing edge and the region of the sliding door 1 adjacent to it enters, when the sliding door 1 is closed.
  • At the bottom of the receiving recess 51 there is a receiving recess 52, into which the safety strip 16 then enters, so as not to be moved from the rest position into the release position by resting on the door frame or the door frame 50 during the closing process.
  • FIGS. 4 and 5 a construction according to FIGS. 4 and 5 can be selected.
  • identical or corresponding parts from FIG. 3 are each designated by 100 reference numerals.
  • a bracket 153, 154 is fastened to a main surface of the sliding door 101 by means of tabs so as to be pivotable about an axis 152 running parallel to the closing edge, and one of the sections 153 extending from the pivot axis 152 is L-shaped and on the safety edge 116 carries the outside of its short, free leg.
  • the other section 154 starting from the pivot axis 152 lies above the upper end of section 153 and extends at an acute angle to the main leg of section 153.
  • the holder 153, 154 When the sliding door 101 is open, the holder 153, 154 is in the position according to FIG. 4, so that the safety strip 116 lies in front of the closing edge of the sliding door 101. In this position, the holder 153, 154 is held by a spring arrangement, not shown.
  • the safety bar 116 can thus act in the same way as was described in connection with the safety bar 16 from FIGS. 1 and 2.
  • the projection 155 comes into engagement with the section 154 shortly before reaching the closed position, as a result of which the holder 153, 154 rotates the axis 152 is pivoted into the position according to FIG. 5, in which the safety strip 116 is located clearly outside the region of the closing edge, which is completely inserted into the receiving recess 151. If the sliding door 101 is opened again, the spring arrangement (not shown) pivots the holder 153, 154 back into the position according to FIG. 4 when its section 154 has come out of engagement with the projection 155.
  • the safety strip 16 can be fastened to the sliding door 1 or the holder 153, 154 with a swivel holder, as shown in FIG. 6.
  • This swivel bracket consists of a two-armed lever 203, 204, which, with its region connecting the legs 203 and 204, is attached to the sliding door 1 so as to be pivotable about the axis 201 or to the bracket mentioned above. At the free end of the lever arm 203, the latter is articulated about the axis 202 on the safety bar 16.
  • the lever 203, 204 is pivoted about the axis 201 into the position shown in broken lines in FIG. 6, in which the Hub body of the pivot axis 202 is located in a recess 205 of the sliding door, whereby a further displacement movement of the safety bar 16 is prevented.
  • the safety bar 16 not only moves to the right but also upwards when moving from its rest position into its release position in FIG. 6, as indicated by the arrow in FIG. 6.
