Definitions

  • This invention relates to an arcuate wall as part of a revolving door, and more particularly to arcuate sidewall members made at least partly of glass.
  • the arcuate side walls in revolving doors are usually made of panels of non-transparent material such as stainless steel, or with annealed glass bent to a right cylindrical shape.
  • a transparent plastic with sufficient scratch hardness to withstand the effect of the constantly passing sealing element (felt or brush) on the edges of each rotating door leaf is not presently available.
  • the costs of manufacturing are high for bent glass in dimensions to be used and manufactured in the relatively small number of pieces in question with the accuracy required.
  • the high cost of the mold for bending further tends to limit the number of door diameters available, thus limiting the architectural freedom in designing an entrance.
  • a problem associated with the use of annealed glass is its tendency to break into large fragments with dangerously sharp edges.
  • tempered or laminated the bent glass in question has led to reluctant acceptance of the use of annealed glass, and the attendant risk of personal injury in the event of breakage. This risk may be reduced somewhat by use of an increased thickness of the glass.
  • an arcuate glass panel made of a number of relatively high, narrow strips of flat glass.
  • Each strip of glass is sufficiently wide, and the joints between the strips are sufficiently narrow, to provide an acceptable view, and the width of each strip is sufficiently narrow to enable a smooth rotation of the central revolving door member and its door leaves, the latter having a felt, brush or other edge sealing member in continuous contact with the surface of the glass panel.
  • the high narrow strips of flat glass may comprise tempered or laminated glass.
  • each strip of glass be glued to its neighboring strip(s) along the vertical, adjacent edges thereof.
  • the high, narrow strips of glass may,,before the mounting thereof, be sealed or joined together by means of an elastic adhesive or sealer.
  • an elastic adhesive or sealer By providing permanent elasticity for the seals between the glass strips, it is possible to build up a large arcuate wall panel or segment away form the mounting side, to transport this panel or segment as a flat member, and to mount this member at the construction site by bending it to the curve desired, as part of the mounting operation.
  • This technique allows for manufacturing of the seals or joints under optimal, controlled conditions in a factory and at the same time allows for fast and therefore inexpensive mounting at the construction site.
  • a glass panel 10 for one arcuate wall for one side of a revolving door may have a radius of 210 cm., a height of the door leaves or strips equal to 230 cm., and a non-transparent, 25 cm. high foot panel in the arcuate side wall, made and mounted in the following way.
  • each strip should be at least 3 inches wide but sufficiently wide so that it subtends an angle in the horizontal plane, which is no greater than 10° as measured from the axis of rotation of the revolving door.
  • the difference in radial distance from the axis of rotation to the center and to either edge of the strip should not exceed 5 mm.
  • the subtended angle should not exceed 9°, and the aforementioned difference in radial distance should not exceed 3 mm.
  • each strip of glass is laminated from 3 layers of 4 mm. thick glass and 2 layers of laminating, 0.76 mm. thick sheets of polyvinylbutyrate (PVB).
  • PVB polyvinylbutyrate
  • the glass strips are placed in a simple mold.
  • the mold may be made of 4 mm. thick plywood 180 x 220 cm., bent to a radius of curvature of approximately 210 cm., defined by two 12 mm. wide, 15 cm. or more high beams cut out of plywood.
  • the mold is lined with a polyethylene (PE) sheet in order to prevent the sealer from sticking to the mold.
  • PE polyethylene
  • the glass strips are placed parallel to one another leaving a 4 mm. wide slot therebetween. The nine slots are then filled with a clear silicone sealer and left to cure to form flexible joints 12.
  • the glass panel After curing of the silicone rubber, the glass panel is removed from the mold and placed in a conventional flat glass transportation box or rack. A second glass panel is now made the same way, and both elements thus manufactured are transported to the mounting site.
  • each glass panel is taken from the transportation unit and placed in the awaiting frame 13 for bending each panel to the desired curve, and releasing the joints 12 from the stresses applied to them during transportation.
  • each strip of glass 11 In order to ensure an acceptable view through the arcuate side wall, it is necessary that each strip of glass 11 have a minimum width of at least 12.5 cm. (5 inches)being preferred. If the glass strips are too wide, a smooth rotation of the rotating body is not possible, or the necessary tight seal between the arcuate wall and the edges of the door leaves will be absent through part of the passage of the door.
  • the maximum acceptable width of the glass strips in the panels according to the invention is 17.5 cm., a width not exceeding 15.5 cm.-being preferred.
  • the maximum acceptable width of the glass strips in the panels according to the invention is 310 mm., and the preferred width is 240 mm. or less.
  • tempered or even annealed glass instead of laminated glass. It is possible to have the long edges of the glass strips ground to accurate shape for fitting in the frame, and the glass mounted to the frame without sealer or with a rigid adhesive; or the sealing of the joints between adjacent strips may be carried out at the mounting site. Sealing of the panels with the strips of glass placed in one plane, leaving the seals unstressed during transportation and stressed when mounted, is another possible modification.
