Definitions

  • the invention relates to a rail construction for supporting recording equipment, such as a movable cart on wheels supporting a camera or the like.
  • the purpose of the invention is to obtain a rail construction in which this disadvantage of the known rail construction can be avoided.
  • the rail construction is built up from coupled profiles, said profiles supporting an elongated rollable or fold-up band of rubber or a similar flexible material, whereby the band also serves as the bearing surface for the wheels of the cart.
  • the rail construction according to the invention can be built making use of the profile parts 1 illustrated in figs 1 - 3, said profile parts having a substantially U-shaped cross section. Between the legs 2 and 3, extending parallel to each other, of the U-shaped profile part 1, at some distance from the free ends of said legs 2 and 3, there is provided a supporting plate 4 which extends parallel to the connecting piece 5 of the U-shaped profile part 1 connecting the legs 2 and 3.
  • each rail For building up a rail construction, across which a cart supporting recording equipment can be moved, a pair of rails extending parallel to each other are provided, each rail being built up from a number of profile parts 1 being in line.
  • a cross girder 7 is supported near its ends by foot supports and it will apparent that by rotating the threaded rods 10 the cross girder 7 can be adjusted in its desired position relative to the floor surface on which the baseplates 12 are supported.
  • the cross girder 7 there are furthermore fixed coupling pieces 14 having a U-shaped section, such that the longitudinal axes of said coupling pieces 14 extend perpendicularly to the longitudinal axis of the cross girder 7.
  • the coupling pieces 14 are thereby open at their upper ends, as will be apparent from fig 6.
  • the profiles 1 may be put in said coupling pieces, so that the profiles, supported by the cross girders 7, can be supported at the correct distance from and parallel to one another.
  • cross girders that are arranged near the connection between two successive profiles 1 are equipped with the coupling pieces 15 illustrated in the figs 9 and 10, instead of with the coupling pieces 14.
  • said coupling pieces 15 are equipped with a pair of pins 16 extending vertically upwards between the legs of the coupling pieces, said pins fitting in holes 6 provided near the ends of the profile parts 1.
  • a solid band 17 made of a flexible material, e.g. rubber or plastic material, is laid across the two rails formed by profile parts being in line.
  • said band 17 has a circular section, as appears from fig 3, and fits between the parts of the legs 2 and 3 of the profile part 1 that project above the baseplate 4, so that said band comes to rest on the plate-­shaped part 4 and will be secured against lateral displacement by the upper ends of the legs 2 and 3.
  • the wheels supporting the cart will be grooved at their circumference, such that the band 17 fits the groove and the cart is secured against lateral displacement relative to the bands supporting the cart.
  • Such a band whose diameter is e.g. 30 mm, can easily be rolled up on a reel or the like, so that a great length of band can be transported in rolled condition from one place to another without any difficulty, and can be easily rolled out across the coupled profile parts 1 when it is to be used.
  • the band then forms an uninterrupted bearing surface for the wheels of the cart supporting the recording equipment, so that such a cart can be moved along the entire distance aimed at, without an objectionable jolt occurring when connecting profile parts are being passed.
  • the profile parts may e.g. be curved in order to make it possible that a curved track is travelled with the cart.
  • the band 17 can easily follow such a curved track of the profile parts.
  • the band may also have a section which deviates from the circular section illustrated in fig 3, as long as it is ensured that during use the band is secured against lateral displacement relative to the profile parts and that the rolls 1 supporting the cart have a profile adapted to the profile of the band, so that the cart is secured against lateral displacement relative to the bands 17 supporting the cart.
