Abstract

PROBLEM TO BE SOLVED: To provide an elevating/lowering device making use of an inclined rail to eliminate the inconvenience when a person get into a carrier, and eliminate anxieties caused by the forward inclination on the inclined rail and possible derailing. SOLUTION: The carrier movable on a rail is equipped with at least two-axle wheels, fitted with a chair to allow a person to turnably get therein, and provided with a device (a pin or the like) to fix the rotation. An auxiliary rail parallel to the inclined rail of an elevating/lowering device is mounted, and when the carrier moves (is elevated/lowered) on the inclined rail, at least one axle is moved on the inclined rail, and at least the other axle is moved on the auxiliary rail to allow the carrier to be kept in a substantially horizontal condition. A fitting structure to prevent the derailing of the carrier is equipped with the inclined rail or the auxiliary rail.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for raising and lowering a person, and more particularly to a device for lifting a boat suitable for assisting marine sports for physically handicapped persons when used for a boat.

[0002]

2. Description of the Related Art Conventionally, when a person with a partially disabled body (ie, a disabled person) enters the sea from a small boat or climbs up from the sea for the purpose of performing marine sports such as scuba diving, For example, September 24, 1999
There is a “lifting device for boats” filed on a date. This means that a horizontal rail is attached to the upper part of the hull, and furthermore, an inclined rail having a length extending from the horizontal rail to the sea is provided, and a human riding member equipped with wheels or sliding devices is mounted on the rail, and the riding member is mounted on the rail. Is suspended by a string-shaped member so as to raise and lower a person. By using this lifting device for boats, there is no need for the caregiver to perform heavy labor, and a person riding on a board member sliding on an inclined rail can be used.
By means of a biasing means such as an electric winch, it can be easily lifted from the sea to the ship.

[0003]

However, in the above-mentioned boat elevating device, when a disabled person gets on the boarding member on the ship, the boarding member faces in the traveling direction. Inconvenience. Also, while moving on the inclined rail, the riding member also leans forward at the same angle as the rail, and there is also a risk that the riding member may come off the rail due to the influence of the wave wind, and this makes the disabled person nervous Had become.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to improve the disadvantages of the prior art and to provide a device that enables a disabled person to easily get on and off the vehicle and to safely move up and down.

[0005]

SUMMARY OF THE INVENTION A riding member movable on a rail comprises a carriage equipped with wheels or a sliding device, and a chair on which a person rides. The chair is mounted rotatably in the horizontal direction with respect to the carrier. The rotating part may be equipped with a bearing.

[0006] The above-mentioned carrier is equipped with at least two wheels (ie, at least four wheels in total on the left and right sides) in front and rear of wheels or sliding devices (hereinafter abbreviated as wheels). An auxiliary rail is provided in parallel above the inclined rail. The upper end of the auxiliary rail is
A horizontal portion is provided so that the wheels can smoothly move from the horizontal rail attached to the hull to the auxiliary rail.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS When a handicapped person gets on the above-mentioned chair on board, a base is fixed to the rear part of the chair-fitting ship and the upper end of the hull on a carriage fitted to the rail, and the base is horizontally mounted on the base. Since the rails can be rotated before and after the ship, for example, if only the chair part is rotated 90 degrees with respect to the traveling direction (horizontal rail direction), the rails will not be in the way and from the wheelchair parked aside You can get on easily.

[0008] After the disabled person gets into the chair, the caregiver rotates the chair so that the chair faces the traveling direction. In that state,
If the rotation fixing pin is inserted, it will not rotate while moving and it is safe. With the above preparations in place, place the riding member with the area where people can get on the horizontal rail.

When the transporter reaches the inclined rail from the horizontal direction, of the front and rear axles, the front axle rides on the auxiliary rail,
When the rear shaft rides on the inclined rail, the transporter on which the person rides moves up and down while maintaining a substantially horizontal state regardless of the angle of the inclined rail.

[0010] The inclined rail or the auxiliary rail is provided with a fitting member (guide rail) having a U-shaped cross section so that the wheels do not come off. , Carriage does not come off the rail.

[0011] As described above, regarding the mechanism in which the transporter moves up and down on the inclined rail while maintaining substantially horizontal,

This will be described with reference to FIG. In this example, the carrier is a,
B and C wheels are provided. In the position, there is a transporter on the horizontal rail, and it is riding on the rail with two axes B and C. The position (1) indicates a state where the a-axis rides on the auxiliary rail and the b-axis floats in the air when the transporter approaches the inclined rail. Is a state in which the a-axis is fitted to the auxiliary rail and the c-axis is fitted to the inclined rail, and the transporter is moving up and down while maintaining the horizontal state. Means that the transporter has arrived at the bottom. Since the front end is equipped with a wheel stopper, even if the suspended string-like member is loosened, the transporter will not escape into the sea.

[0012]

By using the lifting device of the present invention, there is no inconvenience in getting on and off the boat as in the prior art.
In addition, while moving up and down on the inclined rail, the chair is maintained in a substantially horizontal state, and the transporter does not come off the rail, so that it is possible to sit with confidence. The same can be said for lifting a disabled person from the sea on board.

[0013]

[Brief description of the drawings]
