[0002]

2. Description of the Related Art Conventionally, in a mountainous area or the like, there is a narrow road which cannot be used for a transportation vehicle such as an automobile, and there is a road having an upward slope.
Elderly people and people with physical disabilities are physically tired when moving, and in some cases they may not be able to move by themselves.

Therefore, in such a case, it is necessary for the caregiver to carry on his / her back, but such care requires a great deal of labor for the caregiver.

Therefore, it is conceivable to install a transporting device capable of transporting elderly people, persons with physical disabilities, etc. even on narrow roads and on sloped roads.

[0005] For example, as a transportation device, a track is laid on a narrow road, and a carriage is run on the track, and the carriage carries an elderly person or a physically handicapped person. Can be considered.

[0006]

However, in the above-mentioned transportation device, since the track is laid on the narrow road,
When a healthy person who does not need a transportation device walks, there is a problem that the path of the transportation vehicle is an obstacle because the road is narrow.

[0007] In particular, when the number of healthy persons who do not need the transportation device is larger than the number of elderly persons and persons with physical disabilities who need the transportation device, the degree of the above-mentioned problems increases.

[0008]

In view of the above, according to the present invention, a large number of transportation rail struts are erected vertically along the transportation path at intervals in the front-rear direction, and the transportation rail stanchions are carried between the upper portions of the transportation rail struts. The present invention provides a carrying device characterized in that a rail is installed, a carrying device main body is movably attached to the carrying rail, and a carrying stand is vertically installed on the carrying device main body.

The present invention is also characterized by the following configurations.

(1) The transportation rail is laid substantially along the shape of the ground surface, the feeding rail is laid substantially along the transportation rail, and the wiring is laid along the feeding rail. It was possible to supply power to the transportation device body from the overhead power line.

(2) The carriage is pivotally connected to and connected to the lower portion of the carrier body through a pivot / coupling shaft, and the axis of the pivot / coupling shaft is substantially orthogonal to the extending direction of the carrying rail. It is arranged toward the direction, and the carrier can be rocked back and forth around the axis of the pivot / connecting shaft, and the current collecting shoe is located above the carrier and toward the front or rear of the pivot / connecting shaft. Extend the support arm, attach the current collection shoe to the current collection shoe support arm, slide the current collection shoe into contact with the power feeding overhead wire, and roll the current collection shoe support arm on the top surface of the power feeding rail. A moving rolling roller was attached, and the interlocking roller was used to hold the carrier in a substantially vertical hanging posture.

A rail is erected, a carrier body is movably attached to the carrier rail, and a carrier is vertically installed on the carrier body.

In this way, when an elderly person or a physically handicapped person moves, the elderly person or the physically handicapped person or the like gets on the carrier and moves the transporting device main body in the same state. It is possible to easily move the transportation path by stopping the transportation device main body at the location and getting off the transportation platform.

At this time, a large number of carrying rail columns for supporting the carrying rails are installed upright along the side edges of the carrying path so that a healthy person walking on the carrying path can carry the carrying device. Can be kept out of the way.

(2) In the present invention according to claim 2, the transportation rail is laid substantially along the shape of the ground surface, and the power feeding rail is laid substantially along the transportation rail. It is possible to supply power to the transportation device body from the power supply overhead wire that is laid along the power supply rail.

In this way, the transportation rail can be erected at a substantially constant height from the ground surface so that the transportation rail does not hinder a healthy person walking on the transportation path. At the same time, the ground height of the carrier that moves along the transportation rail can be maintained at a substantially constant level, and elderly people and people with disabilities can easily get on and off the carrier at required places on the transportation path. You can

(3) According to the third aspect of the present invention, the carriage is pivotally supported / connected to the lower portion of the carrier body via a pivot / coupling shaft, and the axis of the pivot / coupling shaft is used for transportation. Arranged in the left-right direction, which is substantially orthogonal to the rail extension direction, and the carriage can be rocked back and forth around the axis of the pivot / connecting shaft.
A current collecting shoe support arm is extended above the carrier and toward the front or the rear of the pivot support / connecting shaft, and the current collecting shoe is attached to the current collecting shoe support arm to feed the current collecting shoe to the power supply. In addition to sliding contact with the overhead wire, a rolling roller that rolls on the upper surface of the power feeding rail is attached to the current collecting shoe support arm, and the interlocking roller keeps the carriage in a substantially vertical hanging position. ing.

As described above, the current collecting shoe attached to the current collecting shoe support arm can surely collect the current, and the rolling roller attached to the current collecting shoe support arm moves the carrier in the substantially vertical direction. Since it can be held in the suspended posture, the ride comfort of the driver's cab can be secured well.

In particular, since the user of the carrier, that is, the person who rides on the driver's cab and is transported is an elderly person or a physically handicapped person, the physical burden on the physically handicapped person or the like due to gravity or inertial force. Can be reduced as much as possible so that the carrier can be used with pleasure.
