Definitions

  • the present invention relates to a high-frequency (HF) - tight screen door, consisting of at least one door leaf with a screen plate and a door frame to which the door leaf is pivotally attached, and a contacting device for electrically conductive connection of the screen plate with one ending on the door frame Room screen when the screen door is closed.
  • HF high-frequency
  • the present invention is based on the object starting from the known shielding door, to improve it in such a way that the shielding achieved by the shielding door is completely retained even over a long period of use by providing a reliable and low-wear contacting device.
  • the shield plate is slidably fastened parallel to the door leaf level between two end positions and the end position remote from the door leaf is the closed position of the contacting device and the end position close to the door leaf is the open position of the contacting device.
  • the invention is therefore based on the basic idea of opening or closing the contacting device independently of the pivoting movement of the door, so that there is an exclusively linear movement of the contacting means of the contacting device.
  • the contact means it is therefore possible to move the contact means independently of the movement of the door leaf itself, so that the actuation of the contacting device can take place in a door position in which the contacting means are precisely aligned with one another when the door movement is completed, ie in the closed state of the door leaf , he follows.
  • the contacting device is largely free of wear.
  • the shielding effect of the door can be brought about independently of the closed position thereof, ie there is no inevitable shielding effect when the door is closed.
  • the screen door according to the invention can also be used as a normal room lock. This also significantly increases the service life of the screen door according to the invention in the area of the contacting device.
  • an HF-tight screen door consists of a door leaf 1 and a door frame 2.
  • the door leaf 1 and the door frame 2 preferably consist of a steel or light metal construction, wherein in the door leaf 1 a door panel 3 with sound , heat and / or heat-insulating properties is present.
  • FIG. 2 shows a screen door according to the invention which, in contrast to FIG. 1, is equipped with a double-leaf door leaf.
  • This double-leaf door leaf consists of a passive leaf 4 and an active leaf 5.
  • Umbrella doors according to the invention are used for shielding rooms with a room screen 9.
  • the shielding of these rooms usually consists of a steel sheet that is at least 4 mm thick and completely welded at all joints.
  • the room openings are closed by RF-tight screen doors of the type according to the invention.
  • the shielding requirements for the shielding door are the same as for the room shield.
  • a screen door according to the invention sits in an opening in a wall 10 of a room 7.
  • a room screen 9 is arranged between the door frame 2 and the wall 10.
  • a guide profile 12 made of copper, brass, bronze or steel is arranged between the metallic door frame profile and the room screen 9, whereby a metallic and electrically conductive connection between the frame on the one hand and the room screen on the other hand is achieved.
  • the door leaf 1 is pivotally attached to the door frame 2 with several adjustable door hinges 6. Such a stop is provided that the door leaf with respect to the interior 7 to the outside is opened.
  • the filling 3 of the door leaf 1 is held by a frame 8.
  • the frame profile and the frame profile are designed in a known manner in such a way that there is a labyrinth-shaped gap between them, which is known to be sealed by sealing profiles when the door according to the invention is closed.
  • the door leaf 1 carries a shield plate 16 on its side facing the interior 7.
  • This shield plate 16 advantageously consists of copper, steel or stainless steel.
  • Brackets 17, which have an L-shaped cross section, are used to fasten the shield plate 16.
  • the brackets 17 are in turn attached to the door leaf 1 via piston cylinder devices 18.
  • the piston-cylinder devices 18 are preferably pneumatically or hydraulically operated devices.
  • the shield plate 16 has a peripheral edge web 19 which is angled at right angles in the direction of the interior. Opposite this edge web 19, a contacting device 20 is arranged on the door frame 2, which interacts with the edge web 19.
  • This contacting device 20 is electrically conductively connected to the guide profile 12 and is received by the latter.
  • the contacting device 20 consists of a plurality of pairs of springs consisting of two springs 21, which enclose a contacting gap and lie opposite one another.
  • the springs 21 are arranged in a chamber 22 of the guide profile 12 which is U-shaped in cross section and open towards the edge web 19.
  • the springs 21 together with the edge web 19 form a so-called knife seal, the edge web 19 representing the "blade" of the knife seal.
  • the guide profile 12 projects with its chamber 22 into the opening enclosed by the door frame 2, namely up to the edge web 19 of the shield plate 16 covering the door leaf 1.
  • the edge web 19 closes flush with the in the direction of the door leaf 1 pointing leg 23 of the bracket 17.
  • the leg 23 is guided in a receptacle 24 open on one side on the door frame 8.
  • This guide preferably consists of a shield plate support 25 welded to the bracket 17, which is mounted in a ball bearing 26 with a height-adjustable bracket.
  • the guide profile 12 and its chamber 22 are enclosed on the outside by a cover and securing profile 27.
  • the piston-cylinder device 18 has a piston rod 30 which has a bearing disk 31 at its free end.
  • the bearing disc 31 is surrounded by a guide piece 32 with play, so that there is an articulated mounting, whereby door countersinks can be compensated for.
  • the shield plate 16 can be moved parallel to the door plane between two end positions. In one end position, that is the open position, the shield plate 16 is in a position close to the door leaf 1, and the blade 19 is out of contact with the springs 21.
  • z. B two locking devices 34 are provided on the opposite side of the tapes 6. These locking devices 34 each consist of a preferably hydraulically or pneumatically actuated locking bolt 35 which engages in holes 36 in the door frame 2. Furthermore, a locking and locking device 37 of known type can be attached to the door leaf 1 and the door frame 2.
  • FIG. 4 also shows the shielding of the floor door gap in the area of a between a threshold 39 and the door leaf.
  • the guide profile 12 is fastened to the end face of the threshold 39 facing the interior space 7, the chamber 22 of the guide profile 12 being oriented opposite the edge web 19 (blade) above the upper side of the threshold.
  • the guide profile 12 is connected to the room screen 9.
  • the guide profile 12 is in turn protected from the outside by a cover profile 40 which is fastened to the threshold 39 with screws 41.
  • a dirt protection plate 38 can be raised and lowered in the threshold 39, depending on the position of the shield plate 16, i. H. depending on its closed position or open position, the dirt protection plate 38 is lowered or raised in front of the opening of the chamber 22.
  • FIG. 8 An alternative embodiment of the bottom gap shield is shown in FIG. 8. In this case there is no threshold.
  • a U-shaped contact profile 43 is arranged to run over the entire length of the channel and conductively connected to the room screen 9.
  • the U-shaped contact profile 43 is enclosed from above by a U-shaped cover profile 44.
  • the two vertical legs 45 of the cover profile 44 are designed as receiving chambers into which the vertical legs 46 of the contact profile 43 protrude.
  • a plurality of opposing contact springs 47 are arranged in pairs, between which the vertical leg 46 of the contact profile is guided, so that an electrically conductive connection between the two profiles 43, 44 is given.
  • the cover profile 44 is fastened with its horizontal leg 48 centrally via a cylinder flange 49 on the free end of the piston rod of a double-acting cylinder-piston device 50, in particular a hydraulic or pneumatic device. This allows the cover profile to be raised or lowered.
  • a guide profile 12 is fastened, the chamber 22 of which, with the contacting device 20, 21 arranged therein, facing the edge web 19 (blade) of the shield plate 16.
  • the guide profile 12 is covered by a kick protection strip 51, the kick protection strip 51 having a flat surface which is adapted in its dimensions to the opening of the channel 42.
