Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rain shelter for a cab entrance / exit that prevents the vehicle from getting wet with rain or snow when the cab door of a vehicle is opened / dismounted during rain or snow.

[0002]

[Prior art]

 As an example of a conventional rain avoiding device for a cab entrance, there is a vehicle cultivating device disclosed in Japanese Utility Model Laid-Open No. 61-30526, which is filed by the applicant of the present invention. This vehicle cultivating device is a side opening of a vehicle. This type of door has a foldable shelter covering the upper part of the space from the upper edge to the front edge between the door and the body.

Further, as another example, there is a raindrop adhesion preventing device for a parallel glide type door described in Japanese Utility Model Application Laid-Open No. 60-110567, which is the upper part of the inside of the parallel glide type door. A foldable garment is provided on at least a part of the.

Further, Japanese Utility Model Laid-Open No. 61-56490, which relates to the application of the present applicant, prevents a rain, snow, etc. from adhering to the body or the passenger compartment when getting on and off in a vehicle hinged door device. For this reason, a door device for a vehicle is provided in which a fan-shaped eaves centered on a hinge is provided at the upper end of the door body, and a space for accommodating the eaves is provided when the door is closed on the vehicle body side.

A wind deflector device for a vehicle, in which a wind deflector for guiding traveling wind is provided on the roof of a cab and a duct is provided under the wind deflector device, is described in Japanese Utility Model Publication No. 1-147180. There is.

[0006]

[Problems to be solved by the device]

 Such a conventional vehicle cab entrance rain shelter is necessary because a foldable canopy or fan-shaped eaves appears above the door and entrance even when it is not raining or snowing. There was a defect that the above-mentioned bunches and the like interfered with getting on and off the entrance and exit.

Further, since all of these must be stored in the upper part of the entrance / exit when the door is closed, a storage place for these is required in the cab close to the door, and this storage space is required. As a result, there is a drawback that the passenger's riding space is narrowed.

[0008] Furthermore, a foldable bellows-type shelter expands and contracts each time the door is opened and closed. Therefore, there is a drawback that the folds of the foldable expansion and contraction easily break and lack durability. The present invention solves the above-mentioned problems in the conventional rain shelter device for getting on and off a vehicle, and protects the passenger from getting into and out of the cab without obstructing the entrance and exit of the cab. At the same time, it is an object of the present invention to provide a rain protection device for the entrance and exit of the cab which is durable, easy to store, and looks good.

[0009]

[Means for Solving the Problems]

 According to the present invention, a motor fan is disposed in the center of the roof, a duct extending above the left and right doors is disposed downstream of the motor fan, and an opening for discharging the fan air is provided at each tip of the duct. A door switch for driving and stopping the motor fan by opening and closing the door is connected to the motor fan.

[0010]

[Action]

 When the door is opened, the cab entrance rain protection device of the present invention closes the door switch to drive the motor fan, and the fan wind of the motor fan is directed through the duct toward the outside of the vehicle. A balloon and an air curtain are provided.

On the other hand, when the door is closed, the door switch is opened, the motor fan is stopped, and the blowing of fan air from the opening above the door is stopped.

[0012]

【Example】

 Next, an example of implementation of the present invention will be described below with reference to FIGS. In this embodiment, the wind deflector 2 is provided on the roof 11 of the cab 1, and the motor fan 3 is attached to the central portion of the cab 1 on the roof 11 and the motor fan 3 is installed. As shown in FIG. 2, air is sucked into the air from the rear side of the wind deflector 2 so that the motor fan 3 does not suck in rainwater.

The fan wind sent from the motor fan 3 is guided by a duct 4 to a slit 6 provided above the door 5 of the cab 1 and blown out from the slit 6.

As shown in FIG. 3, the wiring to the motor fan 3 is such that the switch and battery 8 of the relay 7 are connected in series, and the door 5 is provided between the relay 7 and the battery 8. Then, a door switch 9 that is turned on when the door 5 is opened and a manual switch 10 provided near the door 5 of the cab 1 are connected in parallel, and a relay is activated when the door switch 9 and the manual switch 10 are turned on. The current flows through the coil of 7.

Therefore, when the door 5 is opened after the manual switch 10 is turned on in rainy weather, the door switch 9 is turned on, so that a current flows through the coil of the relay 7 to be excited and the relay 7 The switch is turned on, the current of the battery 8 flows to the motor fan 3, the motor fan 3 rotates, and the fan wind blows out from the slit 6 through the duct 4.

Therefore, an air curtain is formed on the upper part of the open door 5, the rain and snow falling between the door 5 and the entrance / exit of the cab 1 are blown away, and when getting on / off the entrance / exit, it gets wet with rain and snow. There is no such thing.

In this embodiment, if a control circuit using a raindrop sensor is used instead of the manual switch 10, the control circuit is turned on in the case of rain or snow without operating the manual switch 10. In this state, when the door 5 is automatically opened, fan air is blown from the slit 6 to form an air curtain, which prevents it from getting wet.

4 and 5 show another embodiment of the present invention, in which the wind deflector 2 is not provided above the cab 1, and the roof 11 of the cab 1 is provided. A motor fan 3 provided with a cover 12 on the upper surface thereof, a duct 4 for guiding the fan wind from the motor fan 3, and an upper portion of the left and right doors 5 of the cab 1 provided at the end of the duct 4. The slit 6 located at is installed.

A door switch 9 is provided on each of the left and right doors 5, and a raindrop sensor 13 is installed at a position exposed on the upper surface of the cover 12 or in the vicinity thereof. When the raindrop sensor 13 detects rain and the door switch 9 is turned on, the control circuit 14 to which the on / off of the door switch 9 is input supplies current to the motor fan 3 to rotate it.

By this rotation, air is ejected from the slit 6 in the same manner as in the above embodiment, an air curtain is formed in the upper part between the opened door 5 and the entrance / exit of the cab 1, and the air from the entrance / exit is removed. It prevents rain and snow from getting wet when getting on and off.

[0021]

[Effect of device]

 As described above, the present invention prevents the vehicle from getting wet with rain or snow when the vehicle is getting on or off the cab by the air curtain formed at the upper part of the entrance / exit.

Then, like the conventional rain protection device for the entrance / exit of a cab, a shelter, such as a rain shelter provided between the upper part of the opened door and the upper part of the entrance / exit, is an obstacle. And there is no difficulty in getting on and off when this yard appears above the entrance and the open door even in rainy weather.

Moreover, since the lack of durability due to the breakage at the folding fold line as in the case where this shed is a fold is eliminated and there is no need to provide a storage place for the shelter in the cab, It has the effect that it can be made spacious and has a good appearance.
