[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wheelchair light emitting device suitable for mounting on a wheelchair.

[0002]

[Problems to be Solved by the Invention] When a physically handicapped person, an elderly person, etc. moves in a wheelchair, it is difficult to swiftly move to the left and right, and it is difficult to avoid running automobiles or bicycles by themselves. . During the daytime, car drivers, cyclists and other pedestrians can visually recognize the wheelchair, and thus car drivers, etc. should be careful to avoid collisions such as slowing down. However, it is difficult to visually recognize a wheelchair from a distance at night or near sunset. Therefore, in the past, the caregiver carried a flashlight or the like to enhance the possibility of visual recognition. But,
The flashlight has a problem in that the direction in which light is projected is limited, and the visual recognizability is improved only in a certain direction. In addition, it is troublesome for a caregiver to hold a flashlight by hand. The present invention has visual recognizability for a wide direction at night or near sunset,
An object of the present invention is to provide a light emitting device for wheelchairs that can be mounted on a wheelchair and emits light by electricity.

[0003]

In order to achieve the above object, in the cane light emitting band of the present invention, a light emitting band having a light emitting portion that emits light by an AC voltage, and a driving portion that supplies an AC voltage to the light emitting portion. And a fixing means for fixing the light emitting band and the drive unit to the wheelchair. Here, the fixing means includes a first planar fastener fixed to the light emitting band,
It is preferable that the second planar fastener is locked with the first planar fastener. The light emitting unit is not particularly limited as long as it emits light by AC driving, but an EL element is particularly preferable because it consumes less power and can be formed thin and is lightweight.
