Abstract

<P>PROBLEM TO BE SOLVED: To solve such a problem that conventional transportation means on a road including a slope or steps such as various mono railways, a transfer machine for a ramp for a sickly person, have a limit for the public use because it is difficult to install a stop station for every house and because the means require skilled drivers. <P>SOLUTION: On a slope with little traffic, a ground transportation vehicle is stably pulled with a plurality of traction cords from a traction vehicle placed on elevated rails installed at the height where the rails are not in the way of going in and out. The operation can be freely carried out on the ground transportation vehicle by only turning on/off a power source. The slow-speed elevated rail traction type ground transportation vehicle is designed so that the power source is always turned off when a hand leaves a switch. Ordinary people in a housing area can freely operate from an optional place to an optional position by such a configuration. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

    The present invention relates to a ground transportation vehicle having a mechanism towed by a tow vehicle on an elevated rail for the purpose of traveling on a slope including stairs.

    Conventional trucks for steep slopes include monorails that run on rails installed on the ground or elevated, rope-drawing suspension type transportation vehicles, and sloping roads for the disabled by modification of the suspension type (JP 2002-46958). There is a transfer machine.

  The transfer device for the sick and the like has a structure in which a sick person transfer box provided as a guest room of a suspended monorail is lowered to the ground at an arbitrary position and gets on and off.

JP2002-46958

    As described above, the monorail as a means of transportation on the steep slope described above, if the rail is installed on the ground so that it can get on and off in front of each house, the rail exists as an obstacle between the house and the road, and it is a daily life. There is a problem in using it as a general transport vehicle, such as a risk of falling if the position of lowering the sick person transport box is wrong in a transport machine such as a ramp for sick people.

    The present invention solves the problems that such conventional monorails and transfer machines such as ramps for the disabled had, and the rails that existed as obstacles between the house and the road, The height is such that it does not interfere with people or moving objects between the roads, and there are no traffic obstacles.The transport vehicle runs on the ground, and a plurality of tow trucks on the elevated rails are operated as the transport vehicle. It is a mechanism that enables stable towing with a tow rope and stops at any position such as in front of the entrance of each house and can get on and off.

    In order to achieve the above object, the present invention connects a ground transportation vehicle and a towing vehicle mounted on an elevated rail with a towing line, and operates the towing vehicle from the ground transportation vehicle side to operate on a slope. It is possible to stop at any position such as on a slope, but if you pull the ground transportation vehicle with a tow line from one place on the elevated rail, the speed of the ground transportation vehicle will be the same as the traveling position on the ground. Because the running speed and running position become unstable due to the difference in running resistance, multiple tow ropes are attached to each position at a distance in the front-rear direction of the tow vehicle on the elevated rail, and each one of the tow lines A structure that stabilizes the speed of the ground transportation vehicle to be equal to the towing vehicle on the elevated rail, and also stabilizes the attitude of the ground transportation vehicle (front-rear direction). It was.

    When towing a ground transportation vehicle from an elevated rail, it is difficult to always maintain a constant vertical distance between the ground transportation vehicle and the elevated rail because there are slope gradient changes and steps on the ground road. The load applied to the vehicle fluctuates, making the ground transportation vehicle unstable and overloading the elevated rail, so the towline that pulls the ground transportation vehicle from the elevated rail is vertically spaced as a tension using a spring. In response to fluctuations, as a safety measure, the extension of the tow rope due to the extension of the spring is limited to a certain length.

    If the strength of the spring of the tow rope pulled from the elevated rail is limited to the force required for the movement of the ground transport vehicle, the spring will extend and the tow rope will be extended when the ground transport vehicle tire is deeply recessed due to a step or the like. Since the limit length is reached and an impact is generated, if the strength of the extension spring of the tow rope is set so as to bear a part of the weight of the ground transportation vehicle, the impact can be absorbed and towed within the extension range of the spring.

    As described above, the elevated rail towing type ground transportation vehicle of the present invention is a ground transportation of a mechanism that pulls from an elevated rail that does not obstruct traffic as a means of transportation leading to a house of people in a residential area connected to a slope including stairs. It is a vehicle that has a structure that stably pulls a ground transport vehicle with multiple tow ropes from a tow vehicle placed on an elevated rail installed at a height that does not interfere with the entrance and exit of each door, and the operation of the ground transport vehicle This is a low-speed elevated rail towing type ground transportation vehicle that can be freely operated only by turning on and off the power supply, and provides a ground transportation vehicle that can be freely used from any place to any position by ordinary people in the residential area. It is.

    In addition, since the vehicle can be run and stopped just by turning on and off the power on the ground transportation vehicle, the stop position can be determined reliably according to the will of the rider.

    Hereinafter, an embodiment of the present invention will be described with reference to FIG.

    In the figure, an elevated rail towing vehicle 3 is placed on the elevated rail 2 with an upper wheel 4 attached to the elevated rail towing vehicle, and an elevated rail with a lower wheel 5 and a drive wheel 6 on the elevated rail 2 supported by the column 1. 2, a spring-loaded tow rope 7 is suspended from the front and rear of the elevated rail towing vehicle 3 and coupled to the front and rear of the ground carriage 8 respectively.

    The elevated rail towing vehicle 3 is driven by starting the electric motor 12 by operating the automatic return type operation switch 11 installed on the ground transport vehicle 8 with the electric power of the power storage device 9 via the wiring 10, and via the chain 13. The drive wheel 6 meshed with the rack 14 attached to the vehicle is driven to advance the elevated rail towing vehicle 3.

    The spring-loaded tow rope 7 will be described with reference to the drawings. Reference numeral 16 denotes an extended state spring 16 in a state where the spring is extended by a load, and reference numeral 17 denotes a shortened state spring 17 in a state where the spring is shortened by a light load. , 18 is a restriction cord that restricts the extension of the spring.

    If ultra-soft tires are used on the wheels of the ground transportation vehicle 7, it has the effect of adjusting the bumps and bumps on the stairs and so on, but it does not hinder the progress because it is pulled from the elevated.

    In addition, because it is a road surface driving method, it is necessary to immediately stop the ground transport vehicle immediately when approaching a person or obstacle in the front, so it is equipped with an obstacle detection device using ultrasonic waves, infrared rays, etc. When an object is detected, it is necessary to immediately shut off the ground transportation vehicle by shutting off the power circuit.

    Furthermore, as a safety device, when the power is cut off, the brake or rotary lock pin is automatically inserted in both the elevated rail tow vehicle and the ground transport vehicle, and both the elevated rail tow vehicle and the ground transport vehicle are completely stopped. And

    In addition, if necessary, a ground transportation vehicle calling device is provided in front of the residence, and an automatic traveling device is required until the ground transportation vehicle reaches the calling position by pressing a button or the like.

It is a side view showing an embodiment of the present invention.
