Definitions

  • This invention relates to tambour doors. These have a plurality of inter-engaged narrow vertical laths capable of developing into curves centred on vertical axes. They are mounted by a guidance system so that from the closed position in which they are usually flat across the front of a cabinet, they can be slid sideways and move around sharp curves near the front corners and then along inside the side walls and finally perhaps around further corners and along inside the back wall.
  • a common problem with such doors is that the laths slip to a slanting position commonly called "crabbing".
  • a known method of overcoming this is to stick cloth or tape to the hidden side of the laths so that each lath is locked to the next in the longitudinal or vertical sense.
  • the aim of this invention is to provide a much simpler guidance system where the door will run freely with minimal risk of crabbing.
  • a tambour door comprising a plurality of vertical laths connected edge-to-edge in a manner permitting curvature of the door about vertical axes, and similarly contoured overhead and bottom tracks by which the laths are guided, characterised in that each lath is suspended from the overhead track, and the bottom track serves only as a guide and not as a support for the lower ends of the laths.
  • the laths will have runners fixed to their ends to co-operate with and be guided by the tracks.
  • the overhead track may have laterally projecting flanges around which engage the runners fixed to the upper ends of the laths.
  • the tracks are of inverted ⁇ -section so that in the overhead track the cross-bar provides the flanges referred to above.
  • the two upstanding portions may be embraced by the runners at the lower ends of the laths or those runners could engage between them.
  • the overhead track may have a section in which an upper part of each co-operating runner engages.
  • a box-section with a longitudinal slot in the underside is suitable.
  • the bottom track may be an inversion of this, while the co-operating runners can be similar to those at the top of the door.
  • each runner For negotiating curves while not allowing too much transverse looseness on the straights, each runner preferably bilaterally engages its associated track at pairs of points separated longitudinally of the track.
  • This guidance system allows the door to turn very sharp corners and indeed at the rear corner of a cabinet the tracks can be doubled back on themselves so that, instead of part of the door when opened lying along the back wall of the cabinet, there can be a double thickness of the door along the side wall.
  • FIG. 1 and 2 The door of Figures 1 and 2 is fitted to a cabinet (not shown in full) with a top 1 and a base 2. Attached to the underside of the top 1 there is a track 3, conveniently of extruded plastics, with a cross section in the form of the Greek letter ⁇ but inverted. It thus provides laterally projecting flanges 4. Runners 5 are engaged with this track and can slide along it. They consist of a shallow channel shaped portion 6 with inturned rims 7 which engage over the flanges 4. The internal width of the channel is greater than the width of the track across the flanges 4 to give the runners 5 scope to go round corners easily. Below the portion 6 there are two downwardly projecting barbs 8 which enter the top of a respective lath 9 of a tambour door and positively engage in holes 10.
  • a track 3 conveniently of extruded plastics, with a cross section in the form of the Greek letter ⁇ but inverted. It thus provides laterally projecting flanges 4.
  • Runners 5
  • each lath has a runner 13 with an inverted U-shaped portion 14 which loosely embraces the ribs 12 of the track 11 and which is fixed to the respective lath by barbs 15 engaging in holes 16, similar to the barbs 8 and holes 10. This runner 13 merely guides and does not support.
  • the laths are interconnected in conventional fashion along their longitudinal edges allowing them to bend around a vertical corner. They will hang vertically under their own weight, which will be carried entirely by the overhead track 3.
  • runners 5 could be wheeled to reduce friction.
  • the runners 13 could be shaped to engage between the ribs 12 rather than outside them.
  • FIG 3 the top 1 of a cabinet and a lath 9 (with its holes 10) of a tambour door are referenced as before.
  • a track 17 is of almost complete box section, but its underside is centrally divided by a longitudinal slot 18.
  • a runner 19 is of approximate T-form, its stem having a neck 20 which fits with clearance in the slot 18.
  • the horizontal portion 21 of the runner extends over and is supported by the inturned flanges of the track 17.
  • the stem widens to fit within the upper end of the lath 9 and has barbs 22 to snap into the holes 10.
  • This arrangement can be inverted and serve to guide the bottom of the suspended door.
  • Figure 4 shows a curved portion of a track 23 with runners 24 engaging the outside in the manner of Figure 2. Over most of their length the runners 24 are clear of the sides of the track 23, but at their ends they have smoothly rounded inwardly projecting protuberances 25 which engage those sides. The laths are therefore firmly guided at every point along the track, but not so firmly as to impede smooth sliding action even at corners.
  • the runners 24 will be forced to spread very slightly as they go around the curve. But the distortion will be very small and well within the capability of a runner made of plastics material. The increased friction arising from the tighter grip will be negligible. In practice however, it is likely that the tolerances will be such that there will be a very slight transverse looseness on the straights, sufficient to minimise or eliminate distortion on the curves.
