Claims (5)

In a railway vehicle having a main wiper device for wiping the windshield of the driver's seat and an auxiliary wiper device provided as a backup for the main wiper device, The auxiliary wiper device has a wiping area that overlaps with the wiping area of the main wiper device, A switching means for switching the operation of the main wiper device and the auxiliary wiper device, The main wiper device includes a detachable manual member used to manually change the position of the wiper blade, The manual component is detachably stored in a storage position that obstructs access to the switching means. A railway vehicle characterized by [this feature].
In the railway vehicle described in claim 1, The switching means includes a knob attached to a changeover switch that switches the power supply circuits of the main wiper device and the auxiliary wiper device, By removing the knob from the aforementioned changeover switch, it is possible to prevent the changeover switch from being operated. The storage box for storing the removed knob is positioned such that the knob cannot be removed by storing the manual component in the storage position. A railway vehicle characterized by [this feature].
In the railway vehicle according to claim 1 or claim 2, The switching means includes a manual switching unit connected to the pivot shaft of the main wiper device, The manual switching unit allows for the manual adjustment of the wiper blade position of the main wiper device by attaching the manual member, which is made of a rod-shaped member. The above manual switching section is equipped with a cover having an opening and closing door, The manual component is detachably installed so as to obstruct the opening and closing of the aforementioned door. A railway vehicle characterized by [this feature].
In the railway vehicle described in claim 2, The aforementioned changeover switch is located in the power distribution panel on the passenger compartment side. A railway vehicle characterized by [this feature].
In the railway vehicle described in claim 4, The distribution panel is provided with a cover that covers the changeover switch, and the inside of the cover has a protrusion. The projection is positioned such that, when the changeover switch is tilted to the side where the main wiper device operates, the knob attached to the changeover switch interferes with the projection. A railway vehicle characterized by [this feature].

Description

This invention relates to a railway vehicle equipped with a main wiper device and an auxiliary wiper device for wiping the windshield of the leading vehicle, and having a structure designed to prevent mishandling and damage to the wipers. On the outside of the windshield of the driver's cab of a railway vehicle, a wiper system (hereinafter referred to as the main wiper system to distinguish it from others) is installed to ensure the driver's visibility even in adverse weather conditions such as rain or snow. This main wiper system is checked for operation during vehicle maintenance and before operation, and repairs or replacements are necessary if it malfunctions. In most cases, the main wiper system is repaired at the factory, but there are cases where a malfunction occurs during operation, rendering the vehicle inoperable. To prepare for such malfunctions during operation, some vehicles are equipped with an auxiliary wiper system that can be used as an emergency measure. Patent Document 1 discloses technology related to a portable wiper device. This portable wiper device (equivalent to the aforementioned auxiliary wiper device) consists of a main body with a wiper unit and suction device mounted on a base member, connected to a battery via a power cord. When the existing main wiper device fails, it can replace the function of the existing main wiper device by being fixed to a suitable position on the windshield surface. Chains attached to the main body and battery are secured to suitable locations on the exterior of the vehicle to prevent them from falling. Patent Document 2 discloses technology relating to a main wiper device, a vehicle equipped with the same, and a railway vehicle. The vehicle includes a wiper arm mounted on the windshield, a wiper shaft supporting the wiper arm and penetrating from the outer surface to the interior of the windshield, a motor that rotates the wiper arm and wiper shaft, and a clutch mechanism that switches between electric drive and emergency manual drive of the wiper. The manual drive is configured to be operated solely by foot. Therefore, when manually driven, the vehicle driver can operate the wiper using a foot-operated wiper drive mechanism without using their hands, thus minimizing interference with driving.
