Definitions

  • the present invention relates to a rubber-elastic seal for doors according to the preamble of claim 1.
  • This seal has the disadvantage that - when the door is closed - it requires two essentially parallel, opposing sealing surfaces, which limits the structural design of the door frame and door leaf.
  • the present invention seeks to provide a seal in which the sealing surfaces interacting with the sealing tabs can be more or less inclined towards one another.
  • the invention also has the advantages of creating a rubber-elastic seal which is insensitive to dimensional inaccuracies, surface properties and geometric dimensions of the push-on rib and of the regions of the door and the door frame which come into contact with the sealing tabs.
  • seal adapts to the geometry of the place of use over a wide range and that the cabinets are not adapted to the seal in the construction of the cabinets and that it can be used both to prevent gas from escaping from a cabinet and to prevent gas from entering a cabinet.
  • the reference number 1 designates the side wall of a control cabinet, which is connected to a Z-profile-shaped door frame 2, which forms a forward-pointing rib 3, which at the top ends rounded into the corresponding rib 3 of the frame lintel.
  • the joint is not welded and therefore leaks.
  • two or more hinges 5 are attached, which carry a door leaf 6.
  • the door leaf 6 is drawn with solid lines in the closed position and indicated by dash-dotted lines in the open position.
  • the gap between the door frame 2 and the door leaf 6 is sealed by a seal 7 placed on the rib 3.
  • the seal 7 is made in one piece from a rubber-elastic material and has two tab-shaped ends.
  • the seal 7 which is produced in the form of profiles, has a cross section which is essentially similar to the shape of a small "h" (FIG. 2).
  • a sealing tab 15 projects beyond the back 13 and is curved in an S shape above the back 13. The end of the sealing tab 15 is directed upwards or is slightly inclined to the vertical.
  • the second leg 17 is essentially the same length as the first leg 11 and forms with it a U that is upside down.
  • a second sealing tab 19 is attached to the leg 17 at its lower end, the cross section of which is smaller than the cross section of the other sealing tab 15
  • the transition from leg 17 to tab 19 takes place in a leaping manner, forming a one-sided shoulder 21.
  • tab 19 initially runs in plane 23 on the inside of leg 17 and is then bent over, so that its end 25 is below the end of the longer one Leg 11 comes to rest.
  • the flap 19 is at most half as long and / or wide as the sealing flap 15.
  • the inner surface of the leg 11 opposite the surface 23 extends at an acute angle to the surface 23, so that the lower ends of the legs 11 and 17 gradually approach each other.
  • the first sealing tab 15 lies essentially above the center of the back 13.
  • the sealing tab 15 which is s-free in the tensioned state comes into contact with the door leaf 6 and the shorter leg 17 with the flap 19 in contact with the rib 3, or with the side of the door frame 2 facing the interior of the cabinet.
  • the flap 19 is slightly bent outwards and lies under the internal stress against the surface of the door frame 2.
  • the sealing flap 15 When the door is closed, the sealing flap 15 is covered essentially parallel to the back 13 and its end, which is initially directed towards the door leaf 6, lies flat against the inside thereof. Both the end 25 of the sealing tab 19 and that of the sealing tab 15 are firmly pressed against the surfaces by the elastic deformation.
  • the same seal 7 can be placed on the rib 3 rotated by 180 degrees (FIG. 4).
  • the sealing tab 19 and its end 25 are bent back so far that the initially existing paragraph 21 serving as a joint groove is less recognizable.
  • the upper sealing tab 15 is also bent more strongly and fits snugly against the inside of the door leaf 6.
  • the sealing tabs fit more tightly on the underlying surfaces when the outside pressure is increased, and thus increase the sealing effect.
  • Deviations that cannot be avoided in the manufacture of sheet metal cabinets are compensated for by the seal 7 according to the invention. If the distance between the end of the rib 3 and the door leaf is less than a predetermined nominal dimension, the upper sealing lip 15 is pressed closer to the back 13. The seal quality is reduced as little as if the distance is greater than the target value because its sealing edge always remains in intimate contact with the inside of the door leaf 6.
  • the seal 7 performs its function without restriction even if the rib 3 is formed by a wide flat profile.
