Definitions

  • This invention relates in general to automobile car top constructions and in particular to a new and useful car top construction including a rigid sliding panel and having a draining system including drains spaced on either side along the length of the car top.
  • a rigid roof frame for supporting a sliding panel, which also includes means for collecting and draining water from the panel.
  • the roof frame is provided with guide rails for the sliding panel; the rails are provided with water channels which run the full length of the automobile.
  • drainage of water is effected through pipes which are arranged at each end of the water channels. Normally, these water collecting troughs, or channels extend over the entire length of the rooftop and this length is usually about twice the length of the sliding panel.
  • the slope of the car top and the corresponding slope of the roof frame has been used for effecting complete drainage of the roof in directions extending either to the front or to the rear, for drainage through pipes at these locations.
  • the water does not have any tendency to drain to either one end of the car or to the other because the roof frame forming the water channels has to be adapted to the fiat form of the car top. It is thus difiicult to adequately drain the water collected in the water channels of the roof frame.
  • the aforementioned disadvantages are overcome by providing a plurality of drainage pipes located at strategic locations along the length of the drainage channels.
  • the pipes are located so that maximum drainage is efiected from the roof by providing more than a single path for the water to drain from the roof.
  • Another important advantage of the present invention is that the drainage pipes are arranged in accordance with the amount of water which is normally present ateach location in a rooftop construction. Investigations have shown that there is very little drainage required in the drainage channel which is attached to the front cross frame. With a roof construction having a sliding panel, when the panel is closed, it is pressed into the frame cross roof structure. However, to make the panel easily maneuverable, it is desirable to have the lateral fit of the panel with the roof structure not too close so that an increase in water admission has to be counted on in these areas.
  • a front water drainage pipe is disposed along each side so as to be spaced by one-quarter the total length of the collecting channel from the front edge.
  • the rear drainage pipe is advantageously disposed at about the spot where the water carrying channel of the sliding roof panel empties into the water collecting channel at the sides.
  • the channels are designed so that the water is always di rected downwardly into the drain at a large sloping angle.
  • the inner upper edge of the water collecting channel, which is supporting the guide rail for the sliding panel is preferably shaped so that it is flush with the upper edge of the guide rail profile. In this manner, the water channel profile will have thegreatest possible height for free downward water flow without having to give up any of the free height available within the car.
  • the attachment of the guide rail for the sliding panel may be made at the inner portion of a supporting ledge formed by the wall of each water collecting channel.
  • a further object of the invention is to provide an improved roof drainage construction.
  • a further object of the invention is to provide an improved roof drainage construction which is simple in design, rugged in construction, and economical to manufacture.
  • FIG. 2 is a longitudinal section of the sliding panel taken along the line II-II of FIG. 1 showing also part of the fixed roof portion;
  • FIG. 3 is a longitudinal section of the roof frame structure shown in FIG. 1 but without the sliding panel, and taken along the line III-III as indicated in FIG. 1;
  • FIGS. 4 to 8 are fragmentary vertical sections taken on the lines IV-IV, V-V, VIVI, VIL-VII and VIII- VIII, respectively, of FIG. 3.
  • the invention as embodied therein includes a roof frame structure generally designated A which includes a fixed roof portion generally designed C which, however, does not form an integral part of the present invention.
  • the frame structure also includes a water channel 1 along the front portion of the vehicle and side water channels 2 for collecting water which drains from the center of the roof structure, and a sliding panel portion generally designated B.
  • the front channel 1 connects to the side channels 2 and drainage pipes 3 are located at their junctures on both sides at the forward end of the vehicle. Drainage pipes 4 are located at the rear end of the vehicle.
  • the fixed roof portion C has been removed from the frame structure as shown in FIG. 1.
  • a supporting ledge for a substantially E-shaped guide rail generally designated 14 is formed by the inner upper rim portion of each side drainage channel 2.
  • the guide rail has an outwardly extending bearing flange portion 15 fitted in a recessed portion of the supporting ledge and thus flush wih the residual rim portion shown in FIGS. 4-8.
  • the sliding connection between the guide rail 14 and the sliding panel B is indicated in dotted lines in FIG. 4 which also shows a portion of the fixed roof part C.
  • the panel B includes a forked guide arm member 16 which extends around and is in sliding engagement with an upper outstanding portion 17 of the guide rail 14.
  • the guide arm member 16 is fastened to a bracket 18' which is secured to the sliding panel portion B.
  • the panel portion B may be moved between open and closed positions by sliding the forked guide arm member back and forth along the guide rail 14.
  • the elevation or height of the inner wall of the drainage channels 2 is increased in height by limiting the spacing between side walls 19 and 20 which define the channels.
  • each channel 2 is closed off at the location 7 and bottom wall 21 of the channel is sloped outwardly and downwardly in several places to effect drainage from the closed off portion to the drain pipe 6 in the forward direction, and from the closed off portion to the drain pipe 4 in the rearward direction.
  • Drainage pipes 5 and 6 are so disposed that the front pipe 5 is spaced from the front end by an amount equal to about a quarter of the length of the sliding panel B, whereas the rear pipe 6 is placed at about the spot where the rear edge G of the sliding panel B will be located when in a closed position.
  • the panel B includes a conventional channel-shaped portion E terminating in an upstanding edge H so that the drain pipe 6 is in the area of the channel portion E of the panel B when the panel is in a closed position with the rear edge G adjacent the front end of the fixed roof portion C, as shown in FIG. 2.
  • Drain pipe 5 is capable of collecting the water which will be received in the front part of the panel by the channel 2, whereas the rear drainage pipe 6 picks up the water which collects in the rear portion of the sliding panel and enters the channel 2 from the channel portion E defined between the portions G and H.
  • the path of flow of the water which is to be drained will be very short and about half the usual length which might be expected.
  • FIG. 3 there is indicated the water channel 2 and the flow conditions prevailing therein.
  • the dotted lines 8 and 9 show the maximum water level which would be reached at the highest point 10.
  • the front end 11 and the rear 12 of the channel 2 are likewise points of highest water level because there is no exit opening at 12 and exit opening of pipe 3 is at a higher level than that of pipes 5 and 6. From the points 10, 11 and 12, the water level drops to the exit opening for pipes 5 and 6.
  • the bottom wall 21 of the channel 2 is bent downwardly and outwardly in a manner to provide an increasing outward slope for the water in the vicinity of the drain openings as indicated in FIGS. 4 to 8.
  • the stepped portion E between G and H of the panel B underlying the fixed roof portion C under certain circumstances carries a large amount of water.
  • the drainage pipe 6 is thus arranged to branch ofi at about this point from the water channel 2 in order to cover any large quantities of water which will be discharged from the channel-shaped portion E.
  • each drainage pipe involves an additional expense, and if possible, an attempt should therefore be made to use the arrangement with only two additional drainage pipes to best advantage. In some instances it may be desirable to dispense with the drainage pipes 3 and 4 which are located in the conventional front and rear positions along the channels 2.
  • a vehicle roof frame construction comprising wall means on each side of said frame defining longitudinally extending side drainage channels and guide rail portions protruding inwardly from each of said side drainage channels, said wall means comprising a substantially horizontal ledge portion and a longitudinally extending guide rail member including an outstanding flange portion disposed tlush with the upper wall of said guide rail portions on said ledge portion, a longitudinally reciprocable roof panel slidable in said guide rail portions, a portion of said wall means defining a cross channel at the front of said frame connecting said side drainage channels, and a plurality of drainage pipes connected to said side drainage channels at spaced locations along the length thereof.
  • a vehicle roof frame construction comprising gutter means on each side of said frame including a substantially vertical outer wall portion and a substantially parallel inner wall portion defining therebetween a longitudinal channel of substantially rectangular cross section, each of said inner wall portions having secured thereto an inwardly protruding, substantially horizontal guide rail portion below the upper edge of said outer wall portion, and a longitudinally reciprocable roof panel slidable in said guide rail portions between an open and a closed position, the bottom walls of said channels being formed with at least two depressions in the region of said closed position of the roof panel, said depressions having 1ongitudinal cross sections defining downwardly directed obtuse angles, and drainage means connected to said channels substantially at the nadir of said angles.
  • parts of said gutter means define at the front of said frame a cross channel connected to said drainage channels, and further including additional drainage means at the junction points of said cross channel with said first-named channels and at the rear ends of said channels.
