Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a direction curtain winding device mounted on an upper part or a lower part of a vehicle body of a route bus, a sightseeing bus or the like.

[Prior Art] Conventionally, in this type of direction curtain winding device, the front glass facing the outside of the vehicle is firmly fixed to the storage box, and an inspection lid is provided on the rear surface of the storage box so that the entire storage box can be removed from the vehicle body. It has become.
Replacement, repair, and inspection of the parts inside the storage box are performed by removing the storage box from the vehicle body and opening the inspection lid.

[Problems to be solved by the invention] The rear surface of the storage box is a part hidden by the direction curtain, which is a convenient place for arranging various parts that should not be seen from the outside of the vehicle. Since the inspection lid is provided, the space in which the parts can be placed is limited, and there is a problem in that there are great restrictions in design.

Further, in the conventional direction curtain winding device, it is necessary to remove the entire storage box from the vehicle body in order to replace, repair, or inspect the components inside the storage box, and there is a problem that a lot of man-hours are required.

An object of the present invention is to provide a vehicle direction curtain take-up device which has a high degree of freedom in designing the arrangement of parts inside a storage box and can easily perform parts replacement, repair and inspection with a small number of steps. To do.

[Means for Solving the Problem] The present invention provides a storage box mounted on the upper portion of a vehicle body and two windings mounted in the storage box in parallel with each other with a predetermined space therebetween so as to be rotatable. A drum, a direction curtain wound around the two take-up drums, a drum driving means for rotating and driving the drum, and a transillumination device mounted between the two take-up drums behind the direction curtain. This is an improvement of a vehicular direction curtain winding device including a lamp and a front glass attached to the front surface of the storage box.

The characteristic configuration is that the rear surface of the storage box is closed, an inspection hole for inspecting the drum, the drum driving means, or the transillumination lamp is provided in a part of the direction curtain, and the front glass is removable. It has been installed in.

[Operation] Closing the rear surface of the storage box, providing an inspection hole in a part of the direction curtain,
By making the front glass removable, you can replace and repair parts of the direction curtain winding device without removing the storage box from the vehicle body.
It is possible to easily perform inspections and the like, and it is possible to increase the degree of freedom in arranging parts with respect to the rear surface of the storage box hidden by the direction curtain.

[Embodiment] Next, an embodiment of the present invention will be described in detail with reference to the drawings.

As shown in FIGS. 1 to 4, the direction curtain winding device 10 is mounted above the middle door 12 of the route bus 11 (FIG. 3), and is provided with a storage box.
13 and two winding drums 14, direction curtains 16 and drum driving means 17
A transmission illumination lamp 18 and a front glass 19 are provided.

The storage box 13 has an open front surface and a closed rear surface. A front glass 19 is detachably attached to the front surface thereof by means of six bolts 29. Inside the storage box 13 are two winding drums 14
Are rotatably mounted in parallel with each other with a predetermined gap therebetween and bearings 23 at both ends. The direction curtain 16 has one end of the two take-up drums 14 fixed to the first take-up drum 14a and the other end thereof fixed to the second take-up drum 14b, so that the take-up drums 14a and 14b are wound without slack. To be The direction guide 16 for the bus is displayed on most of the direction curtain 16.

A feature of this embodiment is that the inspection hole 24 is provided in the center of the portion of the direction curtain 16 where the destination guide is not displayed. The inspection hole 24 has a size such that the winding drums 14a and 14b, the transillumination lamp 18, and the drum driving means 17 can be replaced, repaired, and maintained.

The drum driving means 17 includes a motor 26, a two-row grooved pulley 27, and a first
Pulley 21, second pulley 22, first belt 31 and second belt 32
Equipped with. The motor 26 is mounted on the rear surface of the storage box 13,
The row grooved pulley 27 is attached to the output shaft 28 of the motor 26.
The first pulley 21 is fixed to the first winding drum 14a, and the second pulley 22 is fixed to the second winding drum 14b. In addition, the first belt 31 is provided between the first pulley 21 and the two-row grooved pulley 27,
The belt 32 is stretched between the second pulley 22 and the two-row grooved pulley 27.

The transmissive illumination lamp 18 is mounted behind the direction curtain 16 and in the center of the rear surface of the storage box 13 between the two winding drums 14 and is turned on by a switch (not shown).

Next, a method of using the vehicle direction curtain winding device according to this embodiment, and an inspection and maintenance method will be described.

First, the motor 26 is driven to rotate the two-row grooved pulley 27. This rotational force is transmitted to the first pulley 21 and the second pulley 22 via the first belt 31 and the second belt 32, respectively,
The first winding drum 14a and the second winding drum 14b are rotated. As the winding drums 14a and 14b rotate, the winding drum 14
The display of the destination guide of the direction curtain 16 appearing between a and 14b has changed,
The motor 26 is stopped when the desired display appears.

Further, at night, the transmission illumination lamp 18 attached to the rear of the direction curtain 16 is turned on by a switch (not shown) so that the display of the destination guide can be seen from the outside of the vehicle, and the destination guide of the direction curtain 16 is illuminated.

Next, when inspecting or servicing the direction curtain winding device 10, after the inspection hole 24 provided in the direction curtain 16 is made to appear between the winding drums 14a and 14b by the drum driving means 17, the windshield 19 is provided. Loosen the bolt 29 that is attaching the
Remove 19 from storage box 13. In this state, the inspection hole of the direction curtain 16
By inserting a hand or a tool into 24, it is possible to easily replace the transillumination lamp 18, replace the belts 31 and 32, or inspect the motor 26.

Although the belt and the pulley are used as the drum driving means 17, a chain, a sprocket, a gear or the like may be used. Further, although the winding drum and the transmission illumination lamp are mounted in the horizontal direction in the example, they may be mounted in the vertical direction. Although the front glass is detachable, it may be openable and closable using a hinge or the like.

[Advantage of Invention] As described above, conventionally, the inspection lid is provided on the rear surface of the storage box, the storage box is detached from the vehicle body, and the inspection lid is opened to inspect and maintain the inside of the storage box. According to the present invention, since the inspection window is provided in the direction curtain itself and the front glass is detachably attached, after the inspection hole appears in the direction curtain between the winding drums, only the front glass is removed. Thus, the inside of the storage box can be easily inspected or maintained.

In addition, since the direction curtain take-up device of the present invention closes the rear face without providing the inspection lid on the rear face of the storage box, the degree of freedom in arranging parts on the rear face becomes large, and the design constraint of the direction curtain take-up device is greatly restricted. Can be relaxed.
