Description

4 i 2209140 VEHICLE ROOF CONSTRUCTION The invention relates to a root
construction for buses. especially omnibuses, comprising a roof lining attached to the roof skeleton of the bus, longitudinal luggage shelfs. ventilating ducts 5 and lighting fittings.
T Vith known bus roof constructions the roof lining has usually been cut out from metal sheets. In many cases, the strips have been arranged parallel with the longitudinal axis of the bus. The luggage shelfs and air ducts have also been made of one or perhaps two pieces, followed by the complicated work of upholstering and assembling the roof construction. Time demand and special skill constitute a considerable drawback of this roof construction. Its further disadvantage lies in the prohibitively high manufacturing costs. and the excessively high material losses owing to cutting out the structural materials at site.
i An attempt to eliminate the above disadvantages has been made by having introduced the bus roof construction known as IIVOLVO- ITALIA 9911. where modular elements similar to those customary in aeroplane manufacturing. such as roof. luggage-shelfs and air-duct elements, are used. In this construction the air duct element constitutes a single piece. so that the pitch of seats cannot be varied according to the requirements. A further deficiency is brought about by the roof mounted concealed lighting fittingsq the illuminating power of which have failed to reach the specified le- vel. As a further drawback. the closed luggage shelf is a too complicated and expensive construction. Beyond that. the module elements have been assembled according to traditional mounting technology; i.e. using a large number of screws for clamping each element. Consequently, considerable time. skilled labour and relatively large expenditure are required 4 also by this construction, and to make matters worse, for aesthetic reasons, the screwheads have to be concealed with additional covering elements, Finally. the above luggage compartment of modular size has only permitted the provision of a free passage area for the purpose of an emergency exit through the roof at the expense of the luggage space. reducing the latter below the specified size.
The aim of the present invention is to eliminate the above deficiencies, i.e. to provide a bus roof construction lending itself to be manufactured and assembled considerably simpler and cheaper. without requiring special skilled labour. by the adoption of some structural elements suitable for economical prefebri- cation, and by reducing the number of necessary clamping elements. and by facilitating the accessibility of cable bundles and lighting fittings.
In the bus roof construction of the type described in the introduction the task has been solved by assembling the roof lining and luggage-shelf elements, clamped at their ends exclusively by brackets fixed to the roof skeleton, the luggage shelf elements being provided with a specially shaped profile. On the passenger-space side of this profile for receiving the lighting fitting. a duct is provided. into the clamping flanges of which the longitudinal flanges of the lamp fitting can be snapped, as well as, on the window side, the profile has a closable cable bundle duct and a clamping flange engaging with the longitudinal flange on the passanger-space side of the air duct elements. further the window-side longitudinal flange of the air-duct elements is in force- andlor shapeclosing connection with the clamping profile fixed to the roof skeleton of the bus.
X j In a preferred embodiment, on the upper side of the profile of the luggage shelf element a groove is provided for receiving the bottom flange of the roof element.
In the following, the invention is described in detail with reference to the attached drawings showing as an example an embodiment of the arrangement complying with the invention. In the drawings:
Figure 1 illustrates the roof skeleton of the bus in an isometric view, as viewed from the inside of the bus; is a scenographic, representation of three built-in sectors of the bus roof construction complying with the inven tion, also as an isometric vieW9 where the air duct element of the first sector only is shown; is a drawing showing the complete view of the arrangement of Figure 2; is a section taken along plane IV-IV shown in Figure 3; shows a part of the arrangement of Figure 4; and 7 show the sections taken along planes VI-VI and VII-VII of Figure 4, drawn to a somewhat larger scale, - Figure 2 - Figure 3 - Figure 4 - Figure 5 Figure 6 As shown in Figure 19 the roof skeleton of a motor bus consists of longitudinal beams 1 and transverse beams 2. The roof skeleton as a whole is designated with reference number 3 in the drawing.
in Figure 2, the bus-roof construction complying with the invention is shown in an intermediate stage of assembly. According to the invention, the roof lining and the luggage shelf consists of roof elements 4 and k -I X J luggage-shelf elements 7. accordingly both parts are divided longitudinally into sections and prefabricated to modular size, clamped and fixed at their two ends exclusively by brackets 5 and attached to the roof ske- leton 3. Further. as also shown in Figure 2. the adjecent edges of roof elements 4 longitudinally adjoined to each other are held together by end spreaders 6. In Figure 2. only one of the three sectors of air-duct elements 8, also prefabricated and covering the ventilating duct is shown. According to the invention. only brackets 5 are fixed to roof skeleton 3 in a detachable way, in the present case by bolts K (Figure 4).
As clearly shown in 2igures 2. 3 and 4. each air-duct element 8 is provided with an opening N for accommodating the fans and local lighting fittings (not shown in the drawing). The position of the openings N can always be matched to that of the seats by modifying the lengths and arrangement of air-duct elements 8, i.e. the local illumination and fan can be exa ly directed to the required area.
As it can be seen in Figure 4, to the roof skeleton 3 a longitudinally running clamping profile 9 is bolted. which has a double bend at its lower part to receive the longitudinal flange provided at the window-side upper edge of the air-duct element 8. The lower horizontal part of the clamping profile 9 shown in Figure 4 is shaped to constitute a curtain rail S.
In Pigure 3, three sectors of the roof construction according to the invention are shown, each containing the roof elemenlE 4 attached to the adjacent roof elements 4 through the end spreaders 6, the fixing brackets 5, the luggage-shelf elements 7 and the airduct elements 8. In the arrangement shown, a compensating element 10 is attached to the last sector of the row of air ducts on each side of the roof constriction, 4 since the overall len&th of the air-duct elements 4 seldom equals the length of the passenger space. The ends of the air-duct elements 8 and the compensating elements 10. if any, are terminated by a shut-off element 11. providing a communicedng passage between air ducts of the two sides in a way known in itself.
In Figure 49 it can be aeon that the luggage-shelf element 7 is provided along its full length With a special profile P. This profile P may expediently be extruded from aluminium or plastic. joined with the luggage-shelf element 7 in the course of manufacture.
According to the invention, the profile P. on its side facing the passenger space. is provided with a channel 14 for receiving a lighting fitting 12. The longitudinal edges of a lamp cover B can be snapped into the longitudinal coupling flanges of the channel 14, permitting its easy re-opening. 3Purther, the profile P, on its window side. is provided with a further channel 15 for accommodating a cable bundle 13.
A cover 16 of said channel 15 can be snapped home also in this case.
As shown in some detail in Figure 5. the profile P has a clamping flange 18 mating with a longitudinal flange 17 provided on the air-duct element 8 on its side facing to the passenger space. In the caseg the mating surface of the clamping flange 18 is of arched shape. x-irtherg in this case. the profile 2 is provided on its upper side with a groove 19. shaped to receive the bottom edge of the roof element 4.
In the somewhat larger-scale drawing of Figures 6 and 7, the vertical and horizontal sections of the bracket5 designed to receive the luggage-shelf elements 7 and the roof elemente 4 are shown. In Figure Y J -11 6 the pair of grooves receiving roof elements 4 are marked with number 20. and in Pigure 7 the grooves receiving the luggage-shelf elements 7 from both sides are designated by number 21.
Reverting to Figure 4, it should be noted that the bracket 5 is provided with slot holes 22 for receiving the bolts Ky permitting exact positioning of the bracket 5 in crosswise direction in the course of assembly.
The air-duct element 8 can expediently be made of plastic.
It is placed into position by introducing, first. its lower arched longitudinal flange into the coupling flange 18 of the profile P. then resiliently bending the upper longitudinal flange of the air-duct element 8 inward, the upper longitudinal flange is introduced into the groove of the clamping profile 9. where it is kept firmly in position by elastic deformation of the airduct element 8. Removal of the air-duct element 8 can be performed in the same way, in reversed sense, very simply and quickly.
The luggage-shelf element 7 can be made of foamed plastic in a way known in itself. with a wear-resistant layer applied to its upper and lower surfaces. The profile P is fixed into this foamed plastic in the course of manufacture. The lamp cover B, as already mentioned above, may be made of opal-glass-like plexiglass that can be fixed by snapping it by its flange into the profile P.
As illustrated in Figure 4, for the fixing bolts K and, consequently. for the clamping brackets 5. the roof skeleton 3 is fitted with counterplates 23, provided with tapped holes, attached to the roof skeleton 3 e.g. by welding.
- a - The main advantages of the integrated bus roof construction according to the Invention are as follows:
The entire roof construction can be assembled from prefabricated modular elements, whereby the material losses Inevitably occurring in the course of cutting the sheets to size can be eliminated; Considerably feow clamping and fixing elements are required than in earlier roof constructions, and also these are located a concealed way; The luggage shelf, lighting fittings, air duct and cable bundle are integrated into the roof constructionp all these being clamped to the roof skeleton by the brackets 5; - Less skilled labour is required for its assembly, nevertheless a high standard and stable aesthetic quality is ensured; 3 It can easily be matched to the existing pitch of passenger seats., to which only the longitudinal arrangement of air-duct elements 8 have to be modified depending on the bus size. and simply by adding compensating element 10,, if required; Electric cabling is considerably simplified by clamping the cable bundle 13 to the modular elements and fixing the entire assembly to the structure of the roof skeleton 3 in the course of aaaeufDling the roof construction. instead of laying said cable bundle within the roof skeleton. Thereby the inevitable risk of injuries causing shorts witJain the cable bundles. due to the drilling operations performed at site in the course of mounting of conventional roof constructions, is eliminated; 1 An additional advantage of using resilient roof elements results from reducing the casualty hazards during accidents. Purther. owing to the sound absorption properties of said elements, the noise level in the passenger space is also considerably dampened; Combined reading-lemplyentilation panel may be installed. as a subassembly. into the opening N of the air-duct elements 8, whereby the demand of mounting work of the roof construction to be performed at site is reduced further; By the roof construction proposed by the invention, any standard specification concerning luggage compartment size can be met.
Reference numbers occurring in the appended claims have been inserted merely by way of illustration and are not intended to have any scopelimiting effect whatsoever.
Although the invention has been described in terms of a "bus", that word is intended to cover any road, rail, water-borne or air-cushion vehicle whatsoever.
