Definitions

  • TITLE Sliding door assembly for a shower cabin
  • the present invention relates in general to sliding doors.
  • the invention relates to a sliding door for a shower cabin or a steam cabin, but the principles of the present invention can also be applied in sliding doors for other purposes, for instance cabinet doors or even sliding separation panels for separating large rooms into small rooms.
  • Figure 1 is a schematic cross section of a sliding door assembly for a shower cabin 1 according to the prior art.
  • the cabin has a floor 2 and a threshold 3 below an entrance opening 4. Above the entrance opening 4, the cabin has a horizontal frame bar 5.
  • a door panel 10 is mounted in the door opening 4, so that it can slide sidewards such as to open and close the cabin 1; in the drawing, the sliding direction is perpendicular to the plane of drawing.
  • the upper end of the door panel 10 has carrier wheels 11 riding in the upper guide rail 6; in other words, the door panel is suspended from the frame member 5.
  • the lower end of the door panel 10 has guide wheels 12
  • the cross section of this lower guide rail 7 typically has the shape of an inverted U or of an L with. horizontal leg part 13 and a foot part 14 directed downwards.
  • Mounting the door panel 10 would involve the steps of;, first hooking the guide wheels 12 in the lower guide rail 7, i f-ting the panel until the carrier wheels 11 are higher that the upper guide rail 6, placing the carrier wheels 11 into the upper guide rail 6, and lowering the door panel 10 until the carrier wheels 11 rest on the bottom of the upper guide rail 6.
  • the dimensions are such that the guide wheels 12 are still within the lower guide rail 7, mechanically limiting the horizontal freedom of movement of the lower end of the door panel 10.
  • the threshold 3 must be relatively high, which is annoying because the user has to step over this high threshold, and aesthetically it looks rather bulky.
  • the door panel 10 necessarily is placed a few centimetres inside the shower cabin, with respect to the threshold 3, thus reducing the room available inside the shower cabin.
  • the lower guide rail 7 tends to collect dirt and is difficult to clean. Further, the lower guide rail 7 may be sensitive to wear and tear. Also, the process of placing or removing the door panel is rather difficult.
  • the present invention aims to eliminate or at least reduce these problems.
  • the present invention proposes that the lower end of- the door is held in position magnetically.
  • the lower guide rail 7 and the guide wheel 12 can be omitted entirely, so the threshold 3 can be designed much lower. In fact, it is even possible to omit the threshold 3 entirely.
  • the present invention proposes to use magnets for the upper suspension means, in order to achieve same or similar advantages at the upper end of the door.

  • the type of magnet is not essential, it is preferred to use so-called supermagnets or powermagnets (neodymium) in view of the strong forces these magnets can exert even if they are only small.
  • Figure 2B schematically illustrates the operation of the magnets 21 and 22.

In a similar manner, the second magnetic member 22 can be totally invisible recessed in a threshold, if it is desired to have a threshold.
