Definitions

  • the invention relates to a device for sealing an opening on all sides, in particular a gate in a hall.
  • gates in halls represent such openings, for example, electromagnetically shielded and sealing gates on transformer test halls.
  • the invention is based on the object of specifying a device which enables an opening to be sealed on all sides in spite of the fact that it is surrounded without thresholds.
  • a double-field erection frame SR is used to hold the device.
  • the frame has three vertical supports ST1, ST2, ST3, which are embedded in the floor area FB and are fastened to surrounding building parts, not shown.
  • the three supports limit an opening area TB and a displacement area VB.
  • the opening area TB there is the actual opening TO, which can preferably be walked on and driven over, which has a completely flat, threshold-free floor area FB and which can be sealed on all sides by a flat cover AT.
  • the cover AT can be inserted in the manner of a sliding door for closure from the side into the opening TO or pushed out again to release it.
  • the displacement area VB of the double-field erection frame SR serves to receive the cover AT in the state pushed out of the opening TO.
  • the opening TO in the opening area TB is delimited by a U-shaped, thresholdless border TE.
  • This has a left and right post LP, RP and an upper cross member OT.
  • the thresholdless border is preferably attached to the vertical supports ST1, ST2 of the double-field erection frame SR and preferably has contact surfaces KT on the surfaces of the posts LP, RP and the cross member QT facing the cover AT. If necessary, the contact surfaces can be covered with sealants, for example with rubber bands or metallic contact spring bands, which rest on the surface of the cover when inserted.
  • the device has displacement and lifting means which act on the cover.
  • the shifting means enable the cover to be pushed on or pulled off in a straight line from the side onto or from the surfaces of the sleeveless enclosure.
  • the displacement means of the cover are arranged at an acute angle relative to the surfaces of the border.
  • the cover is mounted on the displacement means rotated by the acute angle in such a way that the cover, at least when pushed on or pulled off, assumes an approximately parallel position relative to the surfaces of the sleeveless bezel and is thus slightly inclined from the side onto the surfaces. or pushed away from it.
  • the lifting means act on the cover in such a way that when the cover is pushed onto or removed from the surfaces of the sleeveless border, it is deposited on the bottom of the opening or is lifted from there.
  • Such a device has the advantage that, despite the fact that the border used to limit the opening is made without a threshold, ie despite the presence of a completely flat bottom area FB inside the opening TO, an all-round sealing of the opening is possible, particularly in the bottom area FB.
  • Another advantage of the device is that it is simple in construction and easy to use.
  • the cover only has to be guided in a single, linear direction of movement when entering or leaving the opening TO.
  • the direction of movement is predetermined by the displacement means.
  • the displacement means With the help of the displacement means, the cover is pushed at an acute angle from the side onto the surfaces of the sleeveless edging or pulled off again.
  • the insertion and removal direction of the cover AT can be described by a vector X which lies in the plane spanned by the space vectors X1, X2 and is rotated in relation to X1 by the acute angle W in the direction of X2 .
  • the cover can be pushed in a straight-line sliding movement along the vector X almost up to the end position on the border TE.
  • the cover seals with the contact surfaces KT on the elements LP, OT, RP of the U-shaped border, preferably using additional sealants.
  • the retracting movement is completed by the cover being set down in the direction of the space vector X3 by the lifting means.
  • the device according to the invention has the advantage that the entire movement sequence of the cover, including settling or lifting, can be effected by a single force acting in a straight line in the direction or opposite direction of the vector X.
  • FIG. 3 shows a schematic diagram of the base area of the exemplary sliding gate of FIGS. 1 and 2.
  • FIG. 3 shows schematically the opening TO with the flat floor area FB and the left, right item LP, RP of the thresholdless border TE.
  • the contact surfaces KT on the tops of the sleeper-less border facing the cover thus lie approximately in one plane.
  • the displacement means of the device are arranged at an acute angle W relative to these surfaces KT.
  • the displacement means have, for example, one that is embedded in the floor area FB without a threshold Running track LS on.
  • the cover AT is now in turn rotated by the acute angle W such that it is mounted on the displacement means in such a way that its surface assumes an approximately parallel position relative to the surfaces KT of the sleeveless enclosure.
  • the cover AT is thus slid slightly from the side onto the surfaces KT laterally or pulled away therefrom in a single, linear displacement movement. During these movements, the approximately parallel arrangement of the cover relative to the surfaces of the enclosure is maintained.
  • the displacement means have a guide rail and guide rollers.
  • the guide rail FS preferably has a U-shaped profile which is open at the bottom and, with the help of the acute angle W relative to the surfaces KT of the thresholdless border TE, preferably extends above the opening and displacement area TB, VB attached by carriers T.
  • Guide rollers KR engage in the guide rail, which are arranged, in particular as shown in FIG. 2, on the upper edge AK of the cover AT along a line rotated by the acute angle W such that the surface of the cover AT facing the opening TO is approximately parallel occupies relative to the surfaces KT of the enclosure TE.
  • the cover AT is thus suspended in the guide rail FS via the guide rollers KR, and is pushed slightly away from the side onto the contact surfaces KT. 2 shows the cover in the pushed-on state, ie covering the opening TO.
  • the linear and slightly oblique sliding movement of the cover is symbolically represented by the vector X, which lies in the plane of the spatial direction vectors X1, X2 and is rotated by the acute angle W relative to X1.
  • the cover AT is placed on the bottom FB of the opening TO immediately upon reaching the postponed state shown in FIG. 2 with the aid of the lifting means in the direction of the vector X3.
  • the displacement means have at least one additional support roller.
  • a support roller QR1, QR2 is provided on the left and right corner of the lower edge UK of the cover.
  • the support rollers have a running direction rotated by the acute angle W relative to the surfaces KT.
  • the cover AT is in turn rotated by the acute angle W so that it is supported on the support rollers QR1, QR2 in such a way that it is in an approximately parallel position relative to the surfaces of the sleeveless enclosure.
  • the displacement means additionally have a running rail LS, which is embedded in the bottom area FB of the opening TO and is arranged at an acute angle W relative to the surfaces KT of the thresholdless border TE for guiding the support rollers QR1 , QR2 on.
  • the support rollers QR1 or QR2 preferably each have a wheel rim LK1 or LK2 rolling on the surface next to the running rail LS and in each case a wheel rim FK1 or FK2 guided in the interior of the running rail LS.
  • the lifting means have at least one inlet trough for the at least one support roller, which is preferably arranged in the floor area in the case of the thresholdless border.
  • a first inlet trough EM1 is provided in the area of the left post LP of the surround TE for the support roller QR1 located on the left corner of the lower edge UK of the cover, and a second inlet trough EM2 in the area of the right post RP for the second support roller QR2 on the right corner the lower edge UK of the cover.
  • the inlet troughs EM1, EM2 are thus located next to the opening TO outside the flat floor area FB.
  • the support roller QR1 or QR2 run into the inlet troughs EM1 or EM2 and cause the cover to settle on the floor FB.
  • its side and top edges SK1, SK2, OK thus rest on the contact surfaces KT of the elements LP, RP, OT of the border TE, and their bottom edge UK on the floor area FB. This ensures that the opening is sealed on all sides.
  • the support rollers QR1, QR2 are preferably arranged offset from one another, ie the running ring LK1 of QR1 is on the right and the running ring LK2 of QR2 is on the left side of the guide rail LS.
  • the inlet troughs are preferably also offset relative to the running rail LS, ie, for example, according to FIGS. 3 and 4, the inlet trough EM1 or EM2 is arranged to the right or left of the running rail LS.
  • Such an arrangement has the advantage that when the cover AT is pushed in, the front, first support roller QR1 attached to the left corner of the lower edge UK of the cover can pass the second inlet trough EM2 in the floor area at the right-hand post RP unhindered.
  • 3 shows just such a position of the cover AT.
  • the flange FK1 of QR1 is located in the area of the running rail LS between the inlet troughs EM2, EM1, while the flange FK2 of QR2 is still in front of the inlet recess EM2 in the rail LS.
  • a catch rail FA is additionally attached to the lower edge UK of the cover.
  • a catch roller FR attached to the bottom FB engages at least when the support roller QR1 passes through the inlet trough EM2 when the cover is pushed in or pushed out. This is e.g. A derailment-safe shift is possible even if a wind load occurs on the surface of the cover.
  • the cover is pushed slightly obliquely from the side onto these surfaces with the aid of the displacement means while maintaining the approximately parallel position relative to the surfaces of the sleeveless edging.
  • a preferred embodiment of such pressing means is already shown in FIGS. 1, 2. These have at least a first and a second pair AR1, AS2 and AR2, AS2, each of a pressure wedge AS1 or AS2 and a catch roller AR1 or AR2 engaging thereon.
  • the first or second pair is assigned to the first or second side edge SK1 or SK2 of the cover AT and is preferably arranged approximately in the middle thereof.
  • the catch rollers AR1 and AR2 are preferably attached to projecting holding webs HS1 and HS2.
  • the catching roller AR1 of the first pair is attached to the left post LP of the sleeveless enclosure TE, while the associated pressure wedge AS1 is attached to the left side edge SK1 of the cover, facing the insertion direction + X.
  • the pressure wedge AS2 of the second pair is attached to the right-hand post RP of the sleeveless edging TE, while the associated catching roller AR2 is located on the right-hand side edge facing the push-out direction -X SK2 of the cover is located.
  • the pressure wedge AS1 or the catching roller AR2 on the left or right side edge SK1 or SK2 of the cover move into the associated catching roller AR1 on the post LP and into the pressing wedge AS2 on the post RP .
  • the pressing means are particularly advantageous if the contact surfaces KT of the enclosure TE and the lower edge UK of the cover AT are provided with sealing means, e.g. Rubber band seals and the like are occupied.
  • the pressing means cause the sealing means to be pressed in the gaps between the side edges SK1, SK2, OK of the cover AT with the elements LP, RP, OT of the border TE.
  • means for electromagnetic shielding are provided to seal the opening TO.
  • These are preferably metallic contact spring strips KF, which are preferably placed all around the opening TO on the contact surfaces KT of the U-shaped surround TE and the lower edge UK of the cover AT.
  • At least the enclosure TE and the cover AT are also designed to be electromagnetically shielding and consist at least of electrically conductive material.
  • the thresholdless border and at least the part of the floor area FB on which the cover AT is placed over the contact spring strips on the lower edge UK is electrically conductive, i.e. high-frequency sealing, and grounded.
  • the displacement means have a drive which acts exclusively in a straight line in the push-on or pull-off direction on the cover AT, preferably an electric drive and preferably embedded in the floor area FB.
  • a drive is shown as an example in FIGS. 1, 4.
  • the drive is accommodated in a channel AK, which is preferably embedded in the floor immediately below or next to the running rail LS.
  • a preferably electric drive motor MT At one end of the channel AK is a preferably electric drive motor MT arranged, which drives a spindle S inserted into the channel AK.
  • the spindle S is used to move a driver M connected to the lower edge UK of the cover AT, so that it can be driven into and out of the opening TO by an electric motor.
  • drives of any other design are possible, for example toothed belt or chain drives.
  • the acute angle W which is an essential structural element of the device according to the invention, between the displacement means and the surfaces of the sleeveless enclosure, on the one hand, and the cover and the displacement means, on the other hand, preferably has a value in the range from 0.3 to 5 degrees.
  • An angle value of approximately 0.5 degrees is particularly advantageous.
  • such an inclination is particularly advantageous if, in addition, means provided in particular for electromagnetic shielding are present on the peripheral edges of the border and / or the cover.
  • the cover can be slanted in or out of the end position from the side without damage or excessive wear, e.g. of metallic contact spring bands KF occurs.
  • the cover represents a gate on a hall, it can be closed and opened almost any number of times without the need for maintenance work on the contact spring bands used for electromagnetic shielding.
  • the flat grinding movement by pushing or pulling on the side causes the surfaces of the metallic contact spring strips to be cleaned from e.g. Corrosion residues.
