  • the known rail arrangement is designed for horizontal, or substantially horizontal, displacement of the beam bearing the hoisting arrangement/hoisting basket, and for this purpose it functions as intended.
  • the patent does not describe the use of drive rollers or drive wheels to provide the horizontal displacement. If such rollers or wheels were to be used, the rolling friction between the drive wheels and the rolling face would be insufficient to ensure propulsion and braking in planes that deviate from a substantially horizontal plane.
  • the arrangement is highly suitable for the transport of goods, articles and the like, where the rail installation is of no importance as regards appearance when it is not in use. However, it is not suitable for use in rail arrangements of the type mentioned in the introduction, where it is desirable that the rail arrangement should be as least visible as possible.
  • the rail arrangement should be mounted inside the wall and arranged in such manner that it does not form a marked, noticeable change to the face of the wall.
  • the object of the invention is to remedy the aforementioned deficiencies of the prior art, and this is achieved with an arrangement of the type mentioned above which is characterised by the features in independent claim 1.

  • the load as such does not relate to the invention, but it may be a load of from some tens to several hundreds of kilos or more, and the arrangement must of course be dimensioned to bear the load in question.

  • the trolley unit 5 may be detachably fastened to the beam 3 by suitable fastening devices such as screw bolts or the like, or it may be fixedly mounted to the beam 3, for example, welded thereto or in another way provided as an integral part of the beam.
  • the profiled rail 2 is formed having an intermediate web portion which at opposite ends is formed having outwardly projecting legs that are provided with respective rolling faces 8a and 8b.
  • Drive wheel 6 and running or support wheel 7 are also provided with respective rolling faces 9a and 9b, and the crab 5 is arranged inside the profiled rail 2 in such manner that the rolling faces 8a and 8b on the rail 2 rest against the rolling faces 9a and 9b on the drive and support wheels 6 and 7 respectively, as can be seen for example in Fig. 4.
  • further drive devices may be provided as indicated schematically in Figures 7 and 8, where the reference numerals 13 and 14 in Fig. 7 indicate an integral chain drive arrangement which can be operated by means of suitable drive couplings connected to the drive wheel 6 or the drive motor 4, and the reference numeral 15 in Fig. 8 indicates that "teeth" or the like may be provided in a bottom portion of the drive wheel 6 and, for example, cooperate with corresponding grooves in the rail 2 (rack and pinion drive).

  • Both drive wheels 6 and support wheels 7 may have a concave or convex form as indicated in Figs. 5 and 6. Here, however, the surface of the drive wheels 6 should be made having a different radius than the corresponding rolling face on the rail, thereby ensuring that the desired small contact area is obtained.

The horizontal distance between the rolling faces of the upper and lower drive and support wheels 6 and 7 may be zero or almost zero, as indicated in Fig. 9, or be offset depending on the need for load-bearing capacity, as is shown in the other figures.
  • the trolley unit or crab 5 may be articulated so that it 5 can be run through horizontal or vertical curves in the rail 2. At least one of the wheels 6 and 7 can be split at the centre of the shaft and pressed together by a spring bank in order to take up irregularities and any other operating disturbances, and to be able to maintain a good grip also in curvatures in the rail arrangement. Furthermore, the trolley unit 5 can be equipped or provided with a suitable safety means (not shown) which locks the trolley unit inside the rail profile if one or more shafts are damaged or snap.
  • the rail 2 When passing, for example, a house corner, the rail 2 will inevitably have a greater distance from the facade surfaces than on a straight stretch of rail.
  • the applicant has found that this problem can be solved by arranging the beam 3 that projects out from the wall at a suitable angle to the rail 2.
  • the rail In the bend around the corner, the rail is also skewed at a suitable angle so that when the beam 3 passes around the house corner, it points straight out and extends so as to provide a suitable distance between the house corner and the suspension means 10.
  • the beam 3 or arm has been arranged at a suitable angle relative to the plane of the rail 2, as illustrated in Fig. 14, the beam 3 can be made to project substantially horizontally, as illustrated in Fig. 13, by turning the rail 2 through a suitable angle.
  • the rail 2 so that it is skewed in the bend area whilst the beam 3 is arranged at an angle relative to the rail, it is ensured that the beam 3 projects out a suitable distance from the facade surfaces in the bend around the house corner, as illustrated schematically in Fig. 15.
  • a beam or arm that is 700 mm may be envisaged. If the arm is angled at an angle of about 60 degrees, this will mean, on a straight length of rail, that the arm in practice extends the necessary 500 mm out from the facade surface. When there is a bend, this distance will be substantially reduced.
  • the rail arrangement 1 is designed and functions in such manner that the rail 2 encircles the trolley unit or crab 5 equipped with one or more drive and supporting wheels, 6 and 7 respectively, having contact or rolling faces, 9a and 9b respectively, which encircle internal, matchingly profiled contact or rolling faces, 8a and 8b respectively, at the bottom and top of the rail 2 in such manner that the moment from a load on an arm or beam 3 projecting from a longitudinal slot in the rail 2 is transferred to internal faces in the rail 2 that is fixed to the building structure, which arrangement is provided for motorised operation and comprises at least one drive/braking wheel 6 with good gripping power in the contact face or faces 8.

Abstract

L'invention porte sur un agencement (1) de rail qui est fixé à une structure de bâtiment et est adapté pour pouvoir supporter, de façon amovible le long d'un rail (2) faisant partie de l'agencement (1), une charge raccordée à une poutre (3), cet agencement étant conçu pour pouvoir se déplacer latéralement. La poutre (3), à son extrémité opposée à l'agencement (1) de rail, est pourvue d'un chariot (5) équipé de roulettes (6, 7) présentant des faces de contact ou de roulement (9a, 9b) qui entourent, de façon coopérante, des faces de contact ou de roulement internes, adaptées, correspondantes (8a, 8b) du rail (2) encerclant le chariot (5). Le rail (2) est conçu comme un rail à profilé pourvu d'une bande qui, aux extrémités opposées, est formée de pattes saillantes orientées vers l'extérieur et pourvue de faces de contact ou de roulement (8a, 8b), et le chariot (cinq) peut être conçu pour un déplacement motorisé caractérisé en ce qu'au moins une roue (6) peut être entraînée par un organe d'entraînement (4), roue (6) sur laquelle la où les faces de roulement ou de contact (9 1, 9 2) génèrent une force de préhension des marchandises avec la ou les faces de roulement ou de contact (8a,8 b) du rail (2) qui sont orientées de sorte qu'un moment de la force provenant de la charge puisse être transféré par l'intermédiaire de la poutre (3) et des roues (6, 7) vers les faces de contact du rail (2).
