Description
Field of the Invention
This invention relates to the skin construction at the junction between a side wall and the roof of a passenger vehicle, and more particularly, to a cant rail and side cover combination at such junction and particularly adapted for a railway passenger car for a rapid transit system.
Description of the Prior Art
In the prior art there have been provided such skin constructions which are each formed with an eaves drop gutter to catch and longitudinally channel the rain falling on the roof of the railway passenger car. It has been noted that such eaves drop gutter are often insufficient to prevent dripping of the rain or of water down along the side of the passenger car. Such undesirable situation arises for instance when heavy or freezing rain or melting snow clogs the eaves drop gutter.
Another relevant consideration relates to the provision of an overhead space to install the door closure and door hanger for doors exteriorly slidable along the side wall of the passenger car. So far, in the prior art such space has been provided by a separate elongated hood or cover laterally fixed to and projecting from the side wall of the car. There results an unaesthetic or outmoded appearance, an annoying protuberance, and the disadvantage of an otherwise unnecessary additional part.
Summary of the Invention
It is a general object of the present invention to provide a cant rail and side cover combination which is adapted to alleviate the above mentioned disadvantages and more specifically to provide a gutter arrangement which is efficient even in the worst weather conditions such as of heavy or freezing rain or melting snow, and which is also aesthetically associated to the slidable doors and forms a space for the door closure and hanger operatively associated to these doors.
It is another object of the present invention to provide a cant rail and side cover combination which is of simple and extrudable skin construction.
It is a further object of the present invention to provide a cant rail and side cover combination which forms a roof gutter longitudinally extending along the upper edge thereof in addition to an eaves drop gutter.
It is still another object of the present invention to provide a cant rail and side cover combination wherein the cant rail and side cover are advantageously and more simply made in two separate parts with a pair of attachment flanges formed on these separate parts respectively and removably secured one against the other for readily removal of the side cover from the cant rail and to thereby give lateral access to the door closure and hanger system which is provided to actuate the doors.
It is a still further object of the present invention to provide a cant rail and side cover combination which forms a roof gutter in addition to an eaves drop gutter and which roof gutter is formed with a recessed bottom resting onto the roof framework and providing for concealed attachment of the cant rail to the body of the passenger vehicle.

FIG. 1 is a cross sectional view taken transversely of a rapid transit passenger car and showing the junction between a side wall and the roof framework of the car in combination with a cant rail and side cover combination according to the present invention;
FIG. 2 is a perspective of one end of a cant rail according to the present invention and forming part of the combination in FIG. 1; and
FIG. 3 is a perspective view of one end of a cant rail according to the present invention and combined with the cant rail to form the combination of FIG. 1.
Description of the Preferred Embodiment
The illustrated cant rail and side cover combination includes a cant rail 1 and a side cover 2 which are each substantially in the form of an extrudable skin member and preferably of aluminum. This cant rail and side cover combination is provided to be installed as the skin at the longitudinal junction between one side wall and the roof framework of a railway passenger car. It should be readily noted that the cant rail and side cover combination may as well be secured in similar manner to other passenger vehicles such as buses, metro cars, etc. In FIG. 1, the side wall of the car is represented by a post 3 and a skin 4 and the roof framework is represented by an arched cross member 5 which is rigidly secured to post 3 and forms a longitudinal junction with the side wall. The roof of the passenger car also includes an inner panel or sheet 6 secured onto the roof framework and a skin 7 extending longitudinally over the central portion of the car.
The cant rail 1 includes an upper longitudinal edge portion 8, a lower longitudinal edge portion 9, and an intermediate longitudinal portion 10 transversely extending intermediate these upper and lower portions. The upper longitudinal edge portion 8 is shaped to form a roof gutter whose bottom 11 is depressed relative to the adjoining edge portion of the intermediate portion 10 and extends lengthwise longitudinally of the car. The bottom 11 is transversely curved in conformity with the transverse curvature of the roof framework to rest evenly and firmly on the latter and be attached thereto. The opposite sides of the roof gutter are defined by transversely upright portions 12 and 13 of the upper edge portion 8. The upright side portion 12 terminates into a flange 14 transversely projecting edgewise in outward direction relative to the car. The upright side portion 12 is fixedly secured to the roof framework by a channel member 15 and rivets, bolts, or the like extending therethrough. The skin 7 has its corresponding lateral edge 16 bent around the free lateral edge of the flange 14. The bottom portion 11 of the roof gutter is transversely inclined outward to define a lower edge portion adjacent the upright side portion 13. The upper edge portion 8 of the cant rail also includes a lip portion 17 which overlies the aforementioned lower edge portion of the roof gutter and is arranged to transversely conceal the latter from view and also a heating cable 18 which may be laid longitudinally in this lower edge portion.
The lower longitudinal edge portion 9 of the cant rail 1 has an L or angular transverse cross section defined by an attachment flange 19 and an inner flange 20. The attachment flange 19 depends transversely edgewise from the lower longitudinal edge of the intermediate portion 10 of the cant rail. The inner flange 20 extends transversely edgewise inward from the lower edge of the attachment flange 19 and abuts edgewise against the corresponding side wall of the passenger car.
The intermediate portion 10 of the cant rail is transversely curved downwardly and outwardly from the lip portion 17 to the lower longitudinal edge thereof. The lower longitudinal edge portion of the intermediate portion 10 is formed with a groove 21 which laterally extends upward therein and outward of the attachment flange 19. This groove 21 is defined by a transversely depending flange 22 in cooperation with the attachment flange 19 from which it is outwardly spaced.
The side cover 2 includes an upper longitudinal edge portion 23, a lower longitudinal edge portion 24, and an intermediate longitudinal portion 25 which transversely extends between the upper and lower portions. The upper longitudinal edge portion 23 of the side cover forms an eaves drop gutter and includes an attachment flange 26 and an outer flange 27 which transversely extend edgewise upright and are laterally spaced apart to define this gutter. The eaves drop gutter underlies the lower edge of the intermediate portion of the cant rail for water dripping therein. The upper edge of the attachment flange 26 is engaged upwardly edgewise into the groove 21 and is releasably secured flat against the other attachment flange 19 by attachment bolts. The latter are thus laterally concealed from view in the eaves drop gutter by the outer flange 27 and allow removal of the side cover 2.
The intermediate portion 24 of the side cover 2 transversely depends edgewise from the outer flange 27 and is laterally spaced outward from the side wall of the car and thus provides a longitudinal space for a door closure and hanger system above a pair of slidable doors. The above system does not form part of the present invention and is schematically represented here by the outline of a pneumatic cylinder 28 and a door hanger bracket 29, upwardly projecting from a slidable door 30 of the car.
The lower longitudinal edge portion 25 of the side cover 2 includes a drip flange portion 31 transversely depending edgewise from the intermediate portion 24 and slightly inclined outward of the door 30 such that any dripping water will at least miss the top portion of the doors. The lower edge portion 25 of the side cover 2 also includes an inner flange portion 32 which transversely extends edgewise from the drip flange portion 31. The inner flange portion 32 defines an outer or free edge which has a longitudinal portion 33 overlying each pair of doors 30 which is operatively spaced from the side wall of the car. The outer or free edge of the inner flange portion 32 operatively abuts at 34 against the side wall longitudinally adjacent or between the pairs of slidable doors 30. The opening defined by each longitudinal edge portion 33 is of sufficient length to allow the full opening course of each slidable door 30.
