Description

[Detailed Description of the Invention] The present invention relates to an air duct structure attached to the ceiling of a bus body, and relates to a ceiling air duct structure for a bus that aims to effectively utilize the lower surface of the air duct.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a cross-sectional view of the bus body according to the present invention, and is a view of the ceiling equipment seen from the interior side.

In the figure, 1 is a bus body, and air ducts 2 and 3 are installed on both sides of the ceiling.

The air ducts 2 and 3 are, as shown in the half-sectional view of FIG. Therefore, it has a closed cross-sectional shape, and is continuously provided in the front-rear direction on the left and right sides of the bus body 1.

The upper end of the panel 4 is fixed to the ceiling, and the lower end is fixed to the body side square pipe 9 as a strength member with screws, etc., and the panel 5 is fixed along the ceiling and is used as a decorative lamp. A clamp 11 to which the wire harness 10 is fixed is fixed.

Moreover, the resin molded member 7 for air duct is the third
As shown in the figure, an engaging part 7a is fitted into the engaging part 6a of the curtain rail 6 at the upper end, and a holding part 7 into which the bottom plate frame 8 is removably inserted is at the lower end.
A bottom plate hinge 7c made of a soft part is formed on the upper part of the holding part 7b provided at the lower end, and acts as a hinge when the bottom plate frame 8 is opened and closed.

On the other hand, the bottom plate frame 8 has a portion other than the air outlet 8a installed in the air ducts 2 and 3.
Speakers, lighting lights, etc. (not shown) are installed at predetermined intervals, and the air outlet 8a portion or other portions are configured to be openable and closable, and are opened and closed when inspecting the lighting lights, harness, etc.

At this time, the opening/closing part of the bottom plate frame 8 can be opened and closed by the bottom plate hinge 7c, since one end is inserted into the holding part 7b of the air duct resin molded member 7 and secured with rivets or screws as appropriate. The other end is removably fitted into a resin molded member 12 which is fixed with screws or the like to the body side square pipe 9 to which the lower end of the panel 4 is fixed.

The resin molded member 12 is made of hard PVC or the like, and as shown in FIG. A hollow portion 12b is provided, and a reinforcing member 13 made of a sheet metal is fitted into the hollow portion 12b.

Further, the cavity 1 provided in the resin molded member 12
A hinge 12 made of soft PVC or the like is attached to the lower surface of 2b.
A lid body 12d is formed which can be opened and closed through c, and this lid body 12d is used when screwing the resin molded member 12 to the body side corner pipe 9 together with the reinforcing member 13 fitted into the cavity 12b. It is designed to be opened and closed.

In addition, in the structure mentioned above, the air outlet 8a part installed in the air ducts 2 and 3 is provided with a grill etc., and is comprised so that the wind direction can be adjusted.

Further, a translucent acrylic plate or the like is attached to the lower surface of the illumination light installed between the air outlets 8a.

As explained in detail above, according to the bus ceiling air duct structure according to the present invention, the bottom plate frame is opened and closed centering on the bottom plate hinge part, so it is easy to replace lighting lights, wiring, etc. arranged in the air duct. It has the effect that it can be used for.

Furthermore, the screws that close the bottom plate frame and fasten the body side square pipes are housed in the cavity of the resin molded member, and the resin is hidden from view from the inside of the car by the lid formed on the molded member. It has the effect of improving the appearance.

In addition, in addition to the air outlet, speakers, lighting lights, etc. are arranged at appropriate intervals on the bottom plate frame of the air duct, so that wiring work and maintenance within the air duct are extremely easy.

In addition, to prevent the lighting lights from protruding into the interior of the vehicle,
It is safe because the occupant does not come into contact with the illumination light and damage it, and the bottom plate frame 8 is flush with the other, resulting in an effect of improving the appearance of the interior.

Furthermore, conventionally, the panels constituting the air duct were made of sheet metal and covered with leather, etc., but according to the present invention, they are constructed by integrally molding resin such as PVC, so they can be made at low cost. play.

Claims (1)

[Scope of Claim for Utility Model Registration] Disposed on both sides of the vehicle ceiling in the longitudinal direction of the vehicle body, and formed into a closed cross-section structure from the ceiling, an inner wall panel, an outer wall panel, and a bottom plate frame attached to the lower ends of both panels. In the air duct, the outer wall panel is formed of resin, and has an engaging part at the upper end that engages with a curtain rail attached in the longitudinal direction of the vehicle body along the ceiling edge, and an engaging part at the lower part. is provided with a bottom plate hinge portion formed in a soft shape, and a holding portion for locking one end portion of the bottom plate frame is provided at the lower end continuous from the bottom plate hinge portion, and the inner wall panel is provided with a holding portion for locking one end portion of the bottom plate frame at the lower part thereof. It has a strength member that is fixed along the direction to reinforce the panel, and is further secured to the strength member through a fastening means, and is the same as a lid body that can be opened and closed by a soft part as a hinge. a resin molded member having a cavity formed in cooperation with the lid; the resin molded member is engaged with the other end of the bottom plate frame so as to cover the lower end of the inner wall panel; For a bus, characterized in that the fastening means exposed in the cavity is released only when opened, and the closed cross section becomes an open cross section by the bottom plate frame, which operates to open centering around the bottom plate hinge part. Ceiling air duct structure.
