Definitions

  • the invention relates to a sliding door construction, which mainly consists of a door element positioned in a frame, which surrounds a doorway opening to which a hollow wall structure is adjacent (US-A-3 400 490).
  • the sliding door can be included with a complete frame into a finished wall or separating structure, whereas the split hollow part together with the wall or separating structure is finished in such a way, that it is not visible, while the doorway opening is bordered by an upper beam and jamb posts.
  • the present invention aims at the furnishing of a sliding door slipping easily with minimal resistance and carried by means of permanent magnets in combination with a steel strip, which is part of the frame, such that a convenient assembly will be possible, while maintenance and wear are inconsiderable.
  • the sliding door construction according to the present invention has a frame, wherein the sliding door is positioned, with a passage opening as a conventional doorway, adjacent to a split hollow all part structure, both sides of which being clad by means of sheet material.
  • the frame of the doorway passage and the hollow wall part constitute a complete entirety.
  • the outer thickness of the hollow split wall part is in conformity with the wall size and the sheet material for the erection of said hollow split wall part can be plastered and finished together with the wall.
  • the construction of the entire device is such that it can be prefabricated and that it can be erected as a whole.
  • the door construction of the type as described in the introduction is provided according to the present invention with a hanging member, consisting of permanent magnets affixed in a slot at the top of the sliding door panel, serving as a means to keep said door in a steel profile, which is part of the frame.
  • rollers or sets of rollers in bearings are provided which are running in a groove in the steel strip, in order to keep on the one side an air cleft between the magnet and the steel, on the other hand to guide the linear movement.
  • the sliding door appliance in question is characterized according to the present invention in that the upper beam at its lower side is provided with a steel strip having a groove in the centre along its entire length, and that the door at its top side is provided with permanent magnets affixed in one line between two steel slot borders (pole sheets), the field of which extending beyond the door, such that said magnets exert a permanent force of attraction towards the steel strip, while a set of at least two rollers, which extend somewhat at the upper edge of the door and which run in the groove of the steel strip, enable the shifting of the door, while lateral turning of the door is prevented by rib-shaped guiding means along the doorway passage at the upper and/or lower edge of the door.
  • the permanent magnets consist of longitudinal blocks of ferrite, lanthanide-iron or lanthanide-cobalt-alloy, which have been sintered and which are polarized in such a manner that the North and South pole are situated in the horizontal plane oppoiste to each other between the slot borders (pole sheets).
  • the material consists of small blocks of Neodym-iron, samarium-cobalt or samarium-cobalt- iron in fine sintered shape.
  • lanthanides or rare earth metals may also be components of the alloy.
  • the block-shaped magnets are positioned alternately with mutual reverse poles between the steel slot borders and are divided from each other by smaller permanent magnets, which are magnetized in the horizontal direction and which fill part of the space between the block shaped larger magnets.
  • the magnetic field is thereby directed in a more elevated way.
  • the erection of the sliding door appliance is furthermore facilitated according to the invention, because the complete frame can be mounted, immured and finished during the raw construction and building up of a premise, without danger of filthiness of the shifting means.
  • the sliding door as such can be mounted during the finishing of the premise by introducing it primarily in a diagonal position into the split hollow wall and then lifting it, until the strip will get within the attractive force of the magnets, whereafter the sliding door will remain in the hanging position and will be operational.
  • the sliding door construction shown in the Figures 1-5 is assembled of a frame with a part (1) for inserting into a hollow split wall and a doorway passage (2), wherein the door element (3) can be moved linearly to and fro.
  • the frame comprises a steel strip (4) and jamb posts (5) confining the doorway passage (2).
  • the frame part (1) for the hollow split wall is for example clad at both sides with sheet material (6), which is comprised all around in a metal strip (4) and which is affixed by means of supporting lathings (7).
  • This construction of supporting lathings and sheet material is for the purpose, that the entire frame will keep its shape and remain in this shape, such that the possibility of premanufacturing exists.
  • the outer width of the hollow split wall coincides with the width of the wall (8), such that the sheet material (6) can be plastered together with the wall (8) and can be finished with a coating layer (9).
  • the jamb posts (5) remain visible as a normal doorway frame.
  • the magnets are separate and there are at least two rollers or sets (11), which are adjusted in height in such a manner, that horizontal shifting is possible, because a small distance is kept.
  • the steel strip (4) has a profile such that the rollers are guided in a straight track.
  • the inner side of the jamb posts (5) is provided with strips of bristles which are adjacent to the sliding door panel such that the sliding door is kept in its vertical position.
  • a special conducting device can be applied at the underside as well.
  • sliding door (3) a normal commercial door as well as a composition of special constructed door elements, for larger sizes or for particular requirements can be used.
  • the magnetic hanging appliance can also be used for other movable separation walls or panels.
  • the construction can be completed furthermore with an automatic service, for example by means of an electrical motor drive.
  • the magnetic elements are sintered permanent paramagnetic polarized blocks. and they consist preferably of ferrite, samarium-cobalt- or neodym-iron-alloy or of other alloys of lanthanides, cobalt and/or iron.
  • the tractive force of the magnet should be 10 to 15 kg higher than the weight of the door.
  • An element of 1 kg neodym-iron has a coercive force such that a tractive force of 120 kg is obtained.
  • the specific weight is 4.833.
