Definitions

  • the present invention relates to a switching device for vehicle, applied to a vehicle guiding system wherein a vehicle is guided by its guide wheels allowed to rotate within a horizontal plane.
  • Fig. 1 shows a prior art vehicle of such type and a switching device for vehicle involved.
  • the vehicle A has a travel wheel 3 of rubber tire and travels on an exclusive track 10.
  • the vehicle A is guided by travel of its guide wheels along their corresponding rail and by detecting the position of the vehicle A relative to the rail, or the variation thereof and by steering the travel wheel 3 accordingly.
  • the track includes a general section and a switching section when it is roughly classified.
  • main rails 11L and 11R are provided on both sides of the track and, in the switching section, an auxiliary rail 12L and movable guide plate 13L, and an auxiliary rail 12R and movable guide plate 13R are added to the main rails 11L and 11R, respectively, as shown in Fig. 1.
  • a sectional view of the vehicle A is shown.
  • the guide wheels which are provided horizontally include two types of guide wheels, one of which is main wheels 1 and the other of which is switching wheels 2.
  • the main wheels 1 are guided by the main rails 11L, 11R while the switching wheels 2 are guided by the auxiliary rails 12L, 12R or guide plates 13L, 13R.
  • the main wheels and main rails are located at an upper stage or position with the switching wheels and auxiliary rails being located at a lower stage or position.
  • the main rail and auxiliary rail have the different heights of guide surface and are not opposed to each other.
  • the main wheels 1 respectively provided on the right and left sides of the vehicle are guided by the right and left main rails 11L, 11R, respectively.
  • the switching wheels of one side are guided by and along a corresponding one of the wheel ways H respectively provided between the main rails and auxiliary rails on both sides of the track.
  • the movable guide plates 13L and 13R are provided in such a manner as to be connected to the auxiliary rails, respectively, and are pivotally supported by pins 13', respectively.
  • the other end of the movable guide plates as in the case of a point installed on a railway, is made rightwardly or leftwardly movable by a switching device 14 whereby the wheel way H is selectively formed on either one side of the track 10.
  • the movable guide plates are pivotally supported by the pins 13' as shown in Fig. 1, it becomes necessary to make dimentional adjustment of the device, make replacement of the worn pins or bushes, effect the supply of oil to the relevant parts, etc. Namely, there remains some problem of maintenance unsettled. Further, since, in such branching device, the movable guide plates are constructed in the form of a straight line, the device has a problem that it fails to provide a smoothness when the vehicle passes through it.
  • the object of the present invention is to provide a switching device for vehicle which eliminates the above-mentioned problems inherent in the prior art, which is simple in construction, which is easy to maintain, and which makes it possible for the vehicle to have wider space for providing a current collector or power rails and to make a smooth switching movement.
  • the present invention has been accomplished by discovering that the problems considered important in the prior art, i.e., the above-mentioned problems that when single guide wheel is guided between two vertical walls of a wheel way, it is brought alternatingly into contact with either of the two vertical walls of the wheel way and is thereby caused repeatedly to make its normal and back rotations and thus frictionally worn very much, are practically not serious problems, that is to say, by discovering that such problems are practically not fatal problems for the reasons that the guide wheel in the switching section is likely to be guided in contact with only one side wall of the wheel way; that, on the other hand, the length of the switching section is remarkably short as compared with the entire length of the track; etc.
  • the present invention has been materialized with conception that the auxiliary rails and movable guide plates need not be high in stiffness since they are solely intended to guide only the guide wheels for obtaining a steering signal unlike those intended to guide the travelling wheels as in case of a railway.
  • the above object of the present invention is attained by arranging the main rails and the corresponding auxiliary rails such that the vertical guiding surface of the former rail and that of the latter rail are opposed to each other with the same height. Further, the above another object of the present invention is attained by preparing the movable rail in a manner that it is integrally and bendably connected at one end to a auxiliary rail or main rail by reducing lateral stiffness of connecting portion and the other free end of the movable rail is made flexible.
  • auxiliary rails 12L and 12R being paired with the main rails 11L and llR, respectively, are provided inside these rails 11L and 11R, respectively.
  • a portion of the auxiliary rail 12L adjacent to an entrance of the switching section S forms a swingable rail 12M, thus defining a switching section M..Assume now that a vehicle A mounted, at its right and left sides, with guide wheels 1 arranged to rotate within a horizontal plane, comes on from a direction indicated by an arrow.
  • the vehicle in accordance with the position of the swingable rail, advances rightwards by having its right guide wheels guided along a right wheel road Hr, or alternatively advances leftwards by having its left guide wheels guided along a left wheel way H£.
  • a vertical guiding surface of the main rail 11 and a vertical guiding surface of the auxiliary rail 12L, 12R or movable rail 12M are same in height and made to oppose each other with one guide wheel 1 interposed or guided therebetween.
  • the swingable rail 12M is constructed in such a manner as to continue from the fixed or stationary auxiliary rail 12L, and a bending portion 20 is made small in the lateral stiffness and thereby made flexible or bendable.
  • a free end portion 12F (indicated by a-one-dot chain line in Fig. 4) of the swingable rail 12M is also made small or less in the lateral stiffness, whereby, when it is contacted with the main rail, it flexes to form a smooth guiding surface.
  • the auxiliary rail 12R of the branching side is also fixedly provided over the substantially entire switching section S.
  • an end 12F' of the auxiliary rail 12R is retreated from a point corresponding to said free end portion F, to such an extent that, when the vehicle advances straight along the rails 11L and 12L, no hindrance arises in passing of its right-side guide wheel 1.
  • the ends 12E', 12F' of the auxiliary rail 12R, as well as the respective ends 12E, 12F of the auxiliary rail 12L and swingable rail 12M, should be extended up to the positions at which the vehicle can reliably be guided by only main rail 11L and opposing main rail 11R. Further, the swingable rail-12M may of course be provided on the auxiliary rail 12R.
  • Figs. 6, 7a, 7b and 7c each show a detailed structure of an embodiment of the swingable rail 12M shown in Figs. 4 and 5.
  • Cross-sectional shapes of main. rail 11L and swingable rail 12M are, however, not limited to those shown in these figures.
  • Fig. 7C the cross section of the free end portion is shown, which joins the movable rail 12M to the corresponding main rail 11L.
  • horizontal and vertical webs of the T-shaped movable rail 12M have their respective parts omitted or cut away, whereby the movable rail 12M is reduced in the lateral stiffness.
  • the swingable rail 12M is made flexible and thereby made capable of being pressed contact with the main rail so that it may have a smooth guiding surface.
  • the cross section (b-b) of an intermediate portion of the swingable rain 12M indicates that no particular fabrication is required in this intermediate portion.
  • a horizontal web thereof has its parts omitted or cut away, whereby reducing the lateral stiffness.
  • the swingable rail 12M may be provided with an embossed portion 21 for reliably introducing the guide wheel 1 residing on the opposite side from the swingable rail 12M into the corresponding wheel road Hr.
  • embossed portion 21 depends on the positional relation between the bending portion 20 and the end portion 12F' of the opposing auxiliary rail 12R, this is, the embossed portion 21 is not required in case that the end portion 12F' is located more toward the entrance of switching section than the bending portion 20, or in case that swingable rails are provided on both sides of the track as will be mentioned later.
  • FIG. 8 there is shown another embodiment of the swingable rail 12M, in which the swingable rail is provided on each of the auxiliary rails 12L, 12R.
  • the one-side swingable rail 12ML is made linear correspondingly to the form of its corresponding main rail while the other-side swingable rail 12MR is made curvilinear.
  • This embodiment provides a structure suitable for the passing of the vehicle through the switching section at high speed.
  • the swingable rails 12ML and 12MR have bending portions 20L and 20R, respectively, and are made operable in interlocking relation with each other.
  • the end portions 12FL and 12FR of the swingable rails 12ML and 12MR are pointed or made sharp, as same as in case of Fig. 6.
  • Fig. 9 shows still another embodiment of the present invention.
  • This embodiment refers to a switching device wherein the auxiliary rails 12L and 12R are disposed outside the main rails 11L and 11R, respectively.
  • the interspace between each main rail and its corresponding auxiliary rail is given as a wheel way H, and the corresponding guide wheels pass through this wheel way H.
  • the above-mentioned elasticity characteristic can be applied to the swingable rails 12ML and 12MR.
  • the switching device already in service for passing a vehicle equipped with the prior art guiding system in a manner simply to make the movable rail at both ends laterally bendable, resulting in a simple machanism of the switching section and in a smooth passing of the vehicle through the switching section.
  • Fig. 10 shows the difference between the vehic guiding system according to the present invention shown at right side and that according to the prior art shown in left side.
  • Ah hl - h2.
  • the present invention has the following effects.
