Definitions

  • the invention relates to a roller door comprising a number of mutually hingedly connected extended lamellae and guiding rails positioned at the ends of the lamellae, in which these ends are inserted and extend themselves in a distance from and parallel to each other along two sides of the door opening and comprise bent parts to bring the lamellae outside the plane of the door opening on opening the door, said lamellae having a substantially flat front face such that the front faces of the lamellae substantially link up with each other in the closed position of the door, the hinge parts of the lamellae being connected with that flat front face.
  • roller doors are applied at a large scale for closing of cabinets, in particular for office furniture.
  • the advantage of such doors is, that they do not occupy space when the cabinet is opened, as the door is within the interior of the cabinet.
  • the guiding rails are not only deflected over 90° at the front of the cabinet, but also near the rear wall of the cabinet. Naturally the useful depth of the cabinet is diminished by this.
  • the guiding rails occasionally are also bent over 180° at the rear wall of the cabinet, so that the lamellae are displaced again parallel to the side wall of the cabinet.
  • the invention has as an object to avoid this disadvantage and to provide such a construction that deflecting of the lamellae over 180° from their path occurs in such a way that the radius of curvature of the outer wall of the bent section of the guiding rail extending over about 180° is hardly larger than the width of the front face of the lamellae.
  • the lamellae are provided with two spaced pivots located behind the front face and near the end edges thereof and being made in such way that the pivots of succeeding lamellae can be slid into each other, a curved guiding plane being formed behind and between the pivots and cooperating with an interior bent wall section of the guiding rail, the leading point of said guiding plane, seen in the direction of movement when opening the door, being located farther away from the front face of the lamellae than the most rearward point of it, said guiding rail immediately before the beginning of the bent section having a narrowing with a smaller internal width than the preceding part but such that no jamming of the lamellae can occur, the bent section joining the narrowing having an increasing width up to over an angle of about 150°, the radius of curvature of the inner wall of the bend being equal to or smaller than the radius of curvature of the curved guiding plane of the lamellae and the radius of curvature of the outer wall of the bend being not more than 25
  • the leading point of the curved guiding plane of the lamellae is spaced further away from the front face of the lamella than the rear point, it is achieved that the guidance of the lamellae mainly occurs by the first mentioned point, whereas only during the returning movement, thus bringing the lamellae towards the closed position, the guiding plane of the lamella cooperates with the inner wall of the bent section of the guiding rail immediately joining the narrowing.
  • the radius of this inner wall is therefore equal to or somewhat smaller than the radius of curvature of the curved guiding plane of the lamellae.
  • the radius of curvature of the outer wall of the bend does not need to be more than 25 % larger than the width of the front face of the lamellae, as a consequence of which the complete bend near the side wall of the cabinet will occupy little space.
  • the length of the narrowing of the guiding rail will be about equal to the width of the front face of the lamellae, the narrowing being applied such that the outer wall of the guiding rail desribes a straight line.
  • the radius of curvature of the inner wall of the bend, immediately joining the narrowing,and the radius of curvature of the guiding plane of the lamellae is about equal to half the width of the front face of the lamellae.
  • the dimensions of the bend may be decreased even further when that part of the inner wall of the bend immediately joining the narrowing has the above mentioned radius of curvature over about 90°, while the radius of curvature thereafter is decreased by 15 to 20 % over about 60°.
  • the radius of curvature of the outer wall of the bend does not have to be more than 12 % larger than the width of the front face of a lamella.
  • the width of the guiding plane as projected on the front face of the lamella and located behind this is 50 to 60 % of the width of the front face of the lamella
  • the distance between the leading point of the guiding plane located farthest from the front face and the front face is from 45 to 55 % of the width of the front face of the lamella
  • the pivot of a lamella present in front of the guiding plane in the direction of movement when opening the door, is constituted by a bent wall section continuing over at least 240° for enclosing a pinshaped part as this has been applied at the other side of a lamella for forming the other part of a pivot.
  • a wall section is connected, extending substantially parallel to the front face of the lamella, and being suitable to cooperate with the bent wall section, forming part of a pivot of an adjacent lamella.
  • Fig. 1 shows a vertical section over a lamella 1, which is guided by guiding rails 2, running parallel to each other and in horizontal planes, and having a substantially U-shaped cross-section.
  • the lamellae have a substantially flat front face 3, which is for example somewhat corrugated or profiled in order to obtain a specific appearance of the outer face of the door in its closed position.
  • Each lamella has a pinshaped pivot 4 and a bent wall portion 5 located opposite it, which together with a pinshaped pivot of a subsequent lamella forms a hinge.
  • an enclosing wall portion 6 is provided opposite the pinshaped pivot 4, such that the bent wall portion 5 is between the pinshaped pivot 4 and the enclosing wall portion 6.
  • each lamella comprises a curved guiding plane 7, provided in such a way that the leading point 8 of this guiding plane is located farther from the front face 3 of the lamella than the rearward point 9 of the guiding plane.
  • the leading point that point is considered that moves in front when the door is slit open.
  • the direction of opening is indicated in Fig. 2 with the arrow V.
  • the bend 11 is connected in such a way that the subsequent straight section 12 of the rail 2 may run substantially parallel to the side wall of a cabinet.
  • the straight section 12 passes via a bent section 13, formed in a special way, into a straight section 14, which may extend up to the vicinity of the straight section 10 of the guiding rail 2.
  • the straight section 14 of the guiding rail 2 may make a certain angle with the straight section 12 as appears from Fig. 2.
  • Fig. 2 shows a number of lamellae in the position as these about will occupy on sliding open the door, thus on displacement of the lamellae in the direction of the arrow V, when a force is exerted on the lamellae via an ultimate, specially shaped lamella la of the door.
  • the guiding rails 2 In order to guide the lamellae 1 in the proper way through the guiding rails 2 the guiding rails 2 have an inner width B, which is larger than the largest thickness D of a lamella 1, such that over the greater part of the path of motion of the lamellae 1 these have a substantial play with respect to the side walls of the rail.
  • the straight section 12 of the guiding rail 2 Prior to the beginning of the bent section 13 the straight section 12 of the guiding rail 2 has a narrowed section 15 with a width B1, which is only 4 % larger than the thickness D of a lamella 1, while the length of the narrowing is about equal to the width E of the front face 3 of a lamella.
  • the lamella 1 is fairly accurately brought in that position, in which the front face 3 of the lamella over its whole width engages the section 16 of the outer wall of the guiding rail just before passing through the bent section 13.
  • the lamellae moving in front of the latter mentioned lamella are diverted by the section 17 of the outer wall of the bent section 13, whereby the lamellae 1B and 1C are turned over nearly the maximum angle with respect to each other.
  • the lamellae 1B and 1C are turned over nearly the maximum angle with respect to each other.
  • the leading point of the lamella 1C or of a lamella 1D preceding it will engage a nearly straight extending section 18 of the inner wall of the guiding rail 2.
  • the lamella 1D is turned back with respect to the lamella 1C, so that for example the front faces of the successive lamellae 1D and 1E will come to ly in one plane again.
  • radius R of the outer wall 17 of the bent section 13 has to be only about 12 % larger than the width E of the front face of a lamella, so that the turning over of the lamellae over somewhat more than 180° can take place within a very limited space.
  • the radius S was substantially equal to the thickness D of a lamella.
  • the inner wall 19 of the bent section 13 joining the part with radius S and extending over about 900, has a radius T which is about 20 % smaller than the radius S.
