Abstract
Description
- The present invention relates to an air diffuser module in a public transportation vehicle, in particular a rail vehicle.
- A linear air diffuser for the delivery of conditioned air to the interior of a passenger vehicle such as a bus, railcar or the like is disclosed in
US 4,354,323 . The diffuser consists of a frame structure with a pair of open ended longitudinally extending delivery channels situated in a generally parallel side-by-side relationship. Each of the channels is turned to extend laterally outwardly in opposite directions and is provided with a curved interior surface on one wall to intercept input air so as to induce eddy current turbulence in the flow characteristics of the delivered air. The input openings to the channels are partially closed by a common longitudinal plate releasably affixed to the frame structure. The lateral peripheral edges of the plate serve to determine the width of a narrow longitudinal input orifice for each of the channels. - A linear air diffuser for the ventilation of a vehicle is disclosed in
DE202012009059U1 . The air diffuser includes a U-shaped extruded profile, and air guide elements formed as extruded profiles, which are clipped into the U-shaped profile. The air guide elements can be clipped in two positions to direct the air flow in two opposite directions. The structure of the linear air diffuser is modular in that the number of air guide elements in each direction can be varied when the air diffuser is assembled. This modularity, however, is limited insofar as the shape of the air guide elements is always the same. Moreover, the linear air diffuser is not a structural member of the vehicle, i.e. it is not possible to attach interior fitments of the vehicle e.g. grab poles or rails, to the air diffuser. - The invention aims to provide an improved linear air diffuser, which has a greater versatility and modularity and can be used in various configurations in different rail vehicles and, once installed, can be easily adapted in case of refurbishing or retrofitting.
- According to a first aspect of the invention, there is provided a linear air diffuser module, comprising:
- an elongated support member having a longitudinal direction, a lower face intended to face an interior space of a vehicle body of a public transportation vehicle and an upper face intended to face a ceiling structure of the vehicle body, the support member including two longitudinal upright wall portions facing one another and laterally enclosing a longitudinal air channel provided with at least one upper opening and at least one elongated lower opening;
- a diffuser plate extending between the two longitudinal upright wall portions to cover the lower opening, the diffuser plate being provided with diffusion openings to direct a flow of air from the air channel to the interior space;
- The support member is a multifunctional structural member of the vehicle body provided with at least two upper C-shaped attachment rails for attaching the linear air diffuser module to the ceiling structure and one or more lower C-shaped attachment rails for attaching interior fitments of the interior space of the vehicle body to the support member, wherein the air channel is located between the two upper C-shaped attachment rails.
- Because the support member is dimensioned as a structural member of the vehicle body, it can be used as interface for fixing various interior fitments, which may include grab poles, grab rails, display screens or partition walls. Because the diffuser plate is separate from the support member, its design can be postponed or altered until the final stage of the design process without having to redesign other parts of the car body or interior trim, in particular the support member or the interior fitments interfaced via the support member to the ceiling structure.
- Preferably, at least one, and preferably each of one or more lower C-shaped attachment rails has a common bottom wall with a respective one of the at least two upper C-shaped attachment rails. The lower C-shaped attachment rail and the respective upper C-shaped attachment rail form together a particularly rigid H-shaped rail, which contributes to the rigidity of the structural member and constitutes an interface to direct forces from the interior fitments directly to the ceiling structure.
- According to a preferred embodiment, at least one of the two longitudinal upright wall portions is provided with a protruding and/or recessed attachment profile and the diffuser plate is provided with a matched attachment portion for attaching the diffuser plate to the support member. Advantageously, the matched attachment portion of the diffuser plate is in sliding engagement with protruding and/or recessed attachment profile. Alternatively, the matched attachment portion of the diffuser plate is clipped into or onto the protruding and/or recessed attachment profile. These embodiments enable a delayed differentiation during the design and the assembly process, i.e. the actual shape of the diffuser plate can be defined at the last minute without involving a complex redesign of the structural member or surrounding parts.
- Other attachment means can be envisaged. In particular, the diffuser plate can be fixed to the support member by means of one or more bolts or screws.
- According to various embodiments:
- The support member can be an extruded profile.
- The air channel can be provided with only one elongated lower opening.

- The diffusion openings can include perforated holes and elongate slots.
- The diffuser plate is preferably an extruded profile.
- According to a preferred embodiment, the support member includes at least one flat portion extending between the air channel and one of the upper C-shaped attachment rails. Advantageously, the diffuser plate is flush with the flat portion of the support member. Alternatively, the diffuser plate can be recessed with respect to the flat portion of the support member.
- According to one embodiment, the support member is made of aluminium. Alternatively, the support member can be made of a glass reinforced plastic or a high-pressure laminate.
- According to another aspect of the invention there is provided a vehicle body of a public transportation vehicle, comprising a ceiling structure and the linear air diffuser module as described above, wherein the linear air diffuser module is located between the ceiling structure and an interior space of the vehicle body, a lower face of the support member of the linear air diffuser module faces the interior space of the vehicle body, the upper face of the support member faces the ceiling structure, the linear air diffuser module is attached to the ceiling structure via mounting brackets inserted in the at least two upper C-shaped attachment rails and at least one interior fitment of the interior space of the vehicle body inserted in and secured to the at least one of the one or more lower C-shaped attachment rails. In particular, the interior fitment can be a grab pole, a grab rail, a draught screen, a partition wall or a passenger counter.
