Description

The invention relates to a rail profile of

  bearing for the rollers of the pallets of advance and re-

  turn of a moving sidewalk moving

  above each other in both directions, in the segment between the return zones. To deal with the future of transport

  people who are currently growing, especially

  In communication nodes such as airports and railway stations, more and more devices for the transport of mechanical persons are being used. The facilities that are particularly well suited for this are moving walkways, which already reach lengths of over 100 m

  in the horizontal type. In such sidewalks

  the forward and return pallets move one above the other respectively in both directions. They are arranged inside a supporting frame which has side railings provided with handrails which also circulate in closed circuit at the top of the balustrades and there are provided sleepers which connect the two lateral cheeks at determined intervals. In moving walkways of this kind, considerable difficulty consists in aligning the paths

  of the rollers of the pallets of advance and

  in relation to each other accurately on the great length of these tracks, and

  maintain their immobilization immutable in space.

  The object of the invention is to facilitate

  the mounting of the raceways of

  allow forward and return pallets of a moving walkway and, in particular, to establish and maintain their relative positions accurately and in a simple manner. There is already known a guide chain for driving vehicles on rails, in which the lead and return strand of the chain

  extend respectively above and below the middle branch of an H-section which is partially

  covered up and closed down by a

  than basic. In this realization, pebbles guide

  ge chains are mounted on both sides on a soul

  by means of the H profile, these circular rollers

  along the side walls of the profile (patent

tannic 1,463,753).

  In this construction, no rollers are provided for the feed and return strands of the force transmission and transmission means. In particular, the device already known gives no indication for easily establishing two roller tracks and to maintain them in this

position.

  The solution to the problem above is

  a U-shaped profile with two branches

  connected by a soul, which is open on one side, and supported flat by a branch, the inner face

  of the support branch representing the roadway

  for the rollers of the return pallets and the outer face of the free branch representing the

  bearing for rollers pallets ahead.

  The advantage of the invention is that, -

  thanks to the use of a common profile for both

  pallet runways, in advance and

  turn, the relative positions of these roadways

  are fixed immutably. Moreover,

  such profiles can be manufactured in large

  that the moving sidewalk can be

  trout from a small number of roll road sections. Mutual longitudinal alignment

  of these tracks is also considerable-

  simplified. The time required for their assembly

is greatly reduced.

  The invention provides the additional advantage

  the fact that, thanks to the mutual

3 2624492

  the rollers of the forward and return pallets, which is made possible by the profile, it is possible to

  to dispense with carrier bodies that were anterior

  usual and necessary to support the moving sidewalk. Each rail section can be fixed directly to the ground, so that it is sufficient to fix them in places, also in their positions

  related. As a result, sleepers that were

  also necessary for the attachment and maintenance of the raceways may be omitted. This required a minimum height of transport level of the moving walkway pallets which can now be significantly reduced. This makes it possible to dispense with the digging of special pits in the floor of the halls in which the moving walkways are provided or, if the moving sidewalks are subsequently installed on these floors, this eliminates the

  need to provide very high ramps for

  the flow of people at the entrance and exit. The

  the central part of the moving sidewalk can be of a

  very flat, although of course it is not

  not excluded from mounting sleepers when this is often

visable.

  Figures in the attached drawing, given only

  by way of example, make it clear how

  vention can be realized. In this drawing, Figures 1 to 4 show details of a

  sidewalk in cross-section, these details indicate

  as also the various embodiments of

the invention.

  In Figure 1, there is shown the track profile for the rollers 2, 3 of the pallets

  in advance and back from a moving sidewalk, which

  slow in one direction the others in the other, in

  the segment between the regions of reference. We have

  diqué that there is provided a U-shaped section 1 provided with two branches 4, 5, supported flat by a branch 5, open

4 2624492

  on one side, the branches being connected by a core 6, the inner face 7 of the support branch representing the

  track for the rollers 3 of the pallets

  turn 8 and the outer face 9 of the free branch

  sensing the raceway for the gaiets 2 of the

  here form the counter-guide for the rollers 3 of the

return notes 8.

  The representation of FIG.

  in which, as in the prior art,

  the profiled rail 1 is mounted on a cross member 12 at the

  of a supporting structure 13. Above the

  carrier slope 13, we can see the side cheeks 14

  of the moving sidewalk and the balustrade 15 which is very

next to the pallet ahead.

  In FIG. 2, the U-profile 1 with two branches

  ches is completed by a third branch 16, which is connected to the free branch by an additional core 17, in the same way that it is connected to the support branch. In this construction, the inner face 18 of the third branch represents the counter-guide for the rollers 2 of the pallet 10. In this embodiment, the rail track section 1 is mounted indirectly on the ground 20, through

  of a support 19, using fastening elements 21

naked in itself.

  In the arrangements of the two figures, the strand

  in advance and the strand back from the trotting chain 22

  rolling tops are provided between the series of pallets and

the pebbles.

  In FIG. 3, the roll road profile is

  25, the track section 1 may be

  directly attached to the floor 20, here also by

fasteners known per se.

  In the arrangements of figures, each path

  of rollers 2, 3 is provided with at least one guide

  lateral 26a, b, c, d, e, f, a, h. In the arrangements of the figures described above, it has not been indicated more precisely that the different branches of the section 1 of the rail can be supplemented by a formation suitable for retaining lubricants.
