Definitions

  • the invention relates to a closure device for an air passage, in which two slotted plates are arranged parallel to one another, one of which is provided with a drive member and can be moved back and forth relative to the other in the direction of the plane of the plate, and in which, when open, the slots in the plates Align and, in the closed position, cover webs on one plate with slots on the other plate and the plates lie close together.
  • the simplest version of such a closure is the so-called slot slide, in which two slotted plates are shifted against each other in such a way that in the open position the slots are one above the other and in the closed position the slot of the first plate overlaps the web of the second plate.
  • the present termination device serves for this purpose.
  • the closure device according to the invention is solving this problem, characterized in that the two plates are connected to one another by articulated arms which are inclined in one direction in the closed position and, when the plates transition into the open position, lift them apart from one another.
  • This first slotted plate is e.g. rigidly arranged.
  • the second slotted plate When the second slotted plate is displaced relative to the first one, it also makes a movement perpendicular to the first plate according to the radius of the articulated arms, whereby it stands out from the first plate. This prevents sliding friction between the two plates during the displacement process.
  • the disadvantages described above are eliminated by the design according to the invention. In the closed position, the plates lie firmly on top of each other again and guarantee the required tightness. The tightness does not change because any wear and tear is compensated for by changing the position of the articulated arm.
  • each of the two outer plates is connected to the middle plate by articulated arms.
  • the Glenkarm connection is provided in a three-plate termination device.
  • This version has the particular advantage that it has approximately the same pressure tightness in both air directions.
  • the middle plate can be arranged immovably, with the drive member on the two attacks the outer plates.
  • one of the two outer plates is arranged to be immovable, the other outer plate is slidable on a guide perpendicular to the plane of the plate, and the drive member engages the middle plate.
  • the conditions of a pressure-impermeable sealing device for air inlets and ventilation ducts are particularly given.
  • the two outer plates are congruently rigidly connected with their slots.
  • the middle plate is moved between the two outer plates, so that in the open state the slots of the three plates are congruent and in the closed state the webs of the middle plate cover the slots of the outer plate.
  • the plates lie close together and the articulated arms are inclined at an angle in an opposite direction.
  • the plates are firmly supported against each other in the closed position and in the open position and lift off from one another during the to-and-fro movement.
  • the movable plate is formed in a conventional manner in that the webs lie in the plane of a plate frame and are rigidly connected to it.
  • a second, particularly expedient and advantageous embodiment of the invention is characterized in that a plate frame supporting the webs is provided and that in the movable plate the webs are separate parts from the plate frame and are arranged under the plate frame and are supported against them by compression springs.
  • each web or lamella Due to the spring attachment of the webs or lamellae, when they cover the slots, they sit according to the spring preload pressure fed up. Due to the resilient suspension of the webs, it is achieved that each web or lamella can adapt to any unevenness in the stationary plate, soiling or wear and tear, without the sealing seat of the other webs or lamellas being adversely affected.
  • the spring preload force of the compression springs is adjustable. By adjusting the spring preload, the closing pressure of the individual lamellae or the individual webs can be adjusted so that optimal tightness is achieved.
  • the stationary plate is coated on the side opposite the movable plate with a sound-absorbing mass and / or if the stationary plate is secured to a support piece by screwing and if there is a between the stationary plate and the support piece sound-absorbing intermediate layer is inserted.
  • the sound-absorbing coating e.g. made of Teroson
  • the sound absorbing intermediate layer e.g. made of 2 - 5 mm thick rubber.
  • Slits 2 are provided, which are designed as elongated windows, extend integrally across the plate transversely to the reciprocating direction and are separated by webs 3, the dimensions of which are larger than those of the window slits 2.
  • a middle plate 4 and a second outer plate 5 are provided parallel to the immovable outer plate 1.
  • the second outer plate 5 is displaceable at right angles to the plane of the plate and is attached to a rod-like guide 7 on a transverse side via an extension 6.
  • the slots 2 of the two outer plates 1, 5 are therefore constantly in alignment.
  • the middle plate 4 is attached on both longitudinal sides via two articulated arms 8 on both outer plates 1, 5 and can be moved both in the plate plane and at right angles to the plate plane.
  • a drive member 9 is attached to the transverse side of the middle plate 4 opposite the guide 7.
  • the articulated arms 8 are arranged in the form of pairs, the two articulated arms of which each have a common axis of rotation 10 on the central plate.
  • the articulated arms 8 leading to the immovable outer plate 1 and the articulated arms 8 leading to the movable outer plate 5 are each of the same length. 1, the articulated arms 8 are inclined in one direction and in the closed position according to FIG. 3, the articulated arms are inclined in an opposite direction.
  • the stationary plate 1 has a stationary or immovably arranged plate 1 which is screwed along its peripheral edge to a support piece 11 which is designed as a peripheral frame.
  • This stationary plate 1 is slotted by providing slots 2 which are designed as elongated windows, extend integrally across the plate transversely to the reciprocating direction and are separated by webs 3, the dimensions of which are larger than those of the window slots 2 .
  • the stationary plate 1 forms a closed plate frame 12, which lies with the webs 3 in a common plane.
  • a movable plate 4 is provided parallel to the immovable plate 1.
  • the movable plate 4 is essentially formed by independent lamellar webs 13 which are free at the ends and which delimit slots between them.
  • Each lamellar web 13 carries on the side facing away from the stationary plate 1 a stiffening rib 15.
  • the webs 13 are wider and longer than the slots 2 of the stationary plate 1.
  • a plate frame 16 of the movable plate 4 is formed by two longitudinal frame struts 17, on which the lamellar webs are suspended and are laterally overhanged by the webs 13 with end pieces.
  • the two longitudinal frame struts 17 are connected to one another by two transverse frame struts 22 which are at a distance from the ends of the longitudinal frame struts and which protrude to the side with end pieces.
  • an end of an articulated arm 8 is articulated, the other end of which is articulated on the frame-like support piece 11.
  • the movable plate 4 can be brought to the stationary plate 1 in the closed position shown in FIGS. 5 to 7, in which the lamellar webs 13 of the movable plate 4 cover the slots 2 of the stationary plate 1, and can be brought into an open position, in which the Slots 2 of the fixed plate are released.
  • two piston-cylinder devices are on the carrier piece 11 8 provided which engage the movable plate 4.
  • Each of the slat-like webs 13 is suspended by means of two screw bolts 19, which each project upwards through one of the two longitudinal frame struts 17 and carry a nut 20 at the free end.
  • a helical compression spring 21 which is pre-stressed, is provided on the screw bolt 19.
