Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention provides a step opening warning device for a vehicle having a step driving means for developing or storing a step attached for the purpose of improving the elevating / lowering characteristics of an occupant when a door is opened in a vehicle having a relatively high floor. Related to the improvement of.

[0002]

[Prior Art]

 This type of step release alarm device for a vehicle is an alarm including a step release detector that electrically detects the opening of a step and at least a buzzer that is driven when the step release detector detects the opening of a step. And consists of. When the step is open, an alarm device including a buzzer operates to warn that the step is open (see, for example, Japanese Utility Model Laid-Open No. 60-23447).

[0003]

[Problems to be solved by the device]

 In this conventional technology, the alarm device always operates when the step is open, but as in a fire engine, for example, the engine is stopped, power is removed from the engine to drive the pump, and the fire is extinguished. If you are working on driving a ladder by extracting power from the engine like a ladder car or a ladder car, there is no problem because the lamp of the alarm does not make a sound, but the buzzer sounds an alarm. Since it continues to be annoyed by this alarm, it hinders work and is not preferable.

In view of the above, an object of the present invention is to enable the operation of the buzzer to be stopped when the vehicle is stopped with the engine running and various work is performed even when the step is open. Another object of the present invention is to provide a step opening warning device for a vehicle.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention is directed to a vehicle equipped with step drive means for driving the step so that the vehicle is deployed outside the vehicle body when the door is opened and is stored in the vehicle body when the door is closed. A step opening warning device for a vehicle comprising a step opening detector electrically detecting the opening of a step and an alarm including at least a buzzer which is driven when the step opening detector detects the opening of the step. In order to provide a step release warning device for a vehicle, the device is provided with a buzzer drive stopping means that opens when the parking brake is applied to stop the drive of the buzzer.

[0006]

[Action]

 In this way, when the vehicle is stopped while the engine is running and various work is being performed, at least the driving of the buzzer that generates a sound can be stopped, so that the steps can be opened. While the occupant uses this step to move up and down while performing work, the buzzer does not generate any noise and the work can be performed without any hindrance.

【Example】

 An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a step opening warning device 10 for a vehicle according to the present invention, and step 12 shows a vehicle opening warning device 10 as shown in FIGS. When the door 16 is opened, it is deployed to a position lower than the floor 18 of the vehicle 14, and when the door 16 is closed, it is pivotally attached by a pin 13 to a bracket 24 that can be retracted so as to be stored in the vehicle body 14A. There is.

As shown in FIG. 4, the step drive means 20 is composed of an air cylinder 26 pivotally supported by a bracket 24 provided below the floor 18 of the vehicle body 14 A. The air cylinder 26 is a solenoid (not shown). Air is supplied through the valve and driven. When the air cylinder 26 extends, step 12 is expanded, and when the air cylinder 26 contracts, step 12 is stored. As can be seen from FIG. 4, the inner edge 12a of the step 12 is restricted by the stepper 24a which is a part of the bracket 24 when the step 12 is open. Therefore, it is possible to prevent the step 12 from swinging when the passenger uses the step 12 to move up and down.

As shown in FIG. 1, the step opening alarm device 10 includes a step opening detector 28 for electrically detecting the opening of step 12 of the vehicle 14, and a step opening detector 28 for opening the step 12. And an alarm 34 including at least a buzzer 30 which is activated during detection. In the illustrated embodiment, the alarm 34 also includes a lamp 32 provided in parallel with the buzzer 30 and the step open detector 28 is provided in series with a parallel circuit of the buzzer 30 and the lamp 32. It consists of a mechanical or semiconductor switch that is closed when 12 is open. In FIG. 1, reference numeral 38 indicates a battery power source, and reference numeral 40 indicates a fuse.

The vehicle step release warning device 10 of the present invention is provided with a buzzer drive stopping means 36 that opens to stop the drive of the buzzer 30 when a parking brake (not shown) is applied. In the illustrated embodiment, the buzzer drive stopping means 36 comprises a mechanical switch or a semiconductor switch which is arranged in series with the buzzer 30 and which opens when the parking brake is applied.

Next, referring to the operation of the step opening alarm device of the present invention, when the vehicle 14 is stopped and a step opening command is issued, air is supplied to the air cylinder 26 which is the step driving means 20. As shown in FIGS. 3 and 4, step 12 is in the deployed position, so that the occupant can be easily moved up and down. The step opening command can be generated by opening the door 16, for example.

In this case, since the switch which is the step opening detector 28 is opened, the lamp 32 is turned on to warn that the step is opened. On the other hand, if the parking brake is not applied, the switch which is the buzzer drive stopping means 36 is closed, and the buzzer 30 operates to generate a warning sound.

On the other hand, when the parking brake is applied while the engine is running to stop the vehicle and various work is to be performed inside and outside the vehicle, the buzzer 30 is opened by opening the switch that is the buzzer drive stopping means 36. Stop. Therefore, the alarm sound from the buzzer 30 is eliminated, and the work can be performed without any trouble without being bothered by the sound from the buzzer. Therefore, when the vehicle is idling or the power take-off of the work vehicle is performed, the parking brake is applied and the vehicle is kept in the neutral state, so that the work can be performed while the buzzer 30 is turned off.

[0014]

[Effect of the device]

 According to the present invention, as described above, when the vehicle is stopped, the door is opened, and the step is opened, the buzzer sounds, but when the parking brake is applied and the engine is running, various operations are performed. Since the drive of the buzzer is stopped, there is a merit that the work can be performed without any trouble without being bothered by the alarm sound from the buzzer.
