SUMMARY OF THE INVENTION The present invention has been made to achieve the above-mentioned object, and comprises a handrail main body having the same inclination angle as a stair, a lifting aid, and connected to the lifting aid. A handrail main body is a cylindrical body having a slit-shaped opening provided in a side wall along a longitudinal direction, and a lifting aid is a sliding member and a sliding member. It consists of a grip projected on the outer peripheral surface of the moving member,
The sliding member can be inserted into the cylindrical body of the handrail body, and
The sliding member is slidably inserted into the handrail main body, the grip protrudes from the handrail main body opening, and the driving wire passes through the handrail main body. At the upper end of the sliding member, another drive wire is connected to the lower end through the handrail body, so that the lifting aid can be raised and lowered.

The cross-sectional shape of the handrail body and the inner surface of the handrail body may be an appropriate shape such as a circle or a square. For example, it is preferable that the outer peripheral surface of the handrail main body is circular because it is easy to grasp when the handrail main body is grasped. Further, the slit-shaped opening provided on the side wall of the handrail main body may be at an appropriate position as long as it is located in the upward direction of the outer peripheral surface and in the lateral direction opposite to the wall surface to which the handrail main body is attached.

The sliding member to be inserted into the handrail body may have any shape as long as it can be inserted into the cylindrical body of the handrail body. A short body having a constant shape is preferred. This cross-sectional shape may be an appropriate shape such as a circle or a square. The shape of the grip protruding from the outer peripheral surface of the sliding member may be an appropriate shape such as a bar, a horizontal L-shape, or a U-shape as long as the grip is oriented toward a person ascending and descending and is easy to hold. When the sliding member is slidably inserted into the cylindrical body of the handrail main body, it is preferable that a person climbing up and down the stairs can easily grasp the grip. For example, if the handrail body slit-shaped opening is provided in the upward direction, the grip may be projected upward from the opening, and the grip may be bent almost horizontally in the opposite direction to the wall surface so as to be substantially L-shaped. This is preferable because it is at right angles to the direction of ascending and descending, and the grip can be easily gripped. Further, it is preferable that the bent portion of the grip be rotatable in the up-down direction, since the grip can be raised when not in use, and does not hinder the grip.

[0008] The drive device for moving the drive wire may be any suitable drive device as long as the person ascending and descending can grip the grip of the elevating aid and move up and down.

The handrail body, sliding member and grip may be made of any suitable material such as wood, synthetic resin and metal. The material of the drive wire may be any suitable material such as metal, synthetic resin, and natural fiber. For example, it is preferable that the handrail main body, the sliding member, and the grip are made of wood and the drive wire is made of metal in terms of aesthetic appearance and durability.

When the handrail body, the sliding member and the grip are made of wood, the sliding member is provided in the cylindrical handrail body, the end of the grip is inserted through the opening, and the grip is bonded to the sliding member. Then, the lifting aid can be easily attached to the handrail main body, which is preferable. When the handrail body, the sliding member and the grip are made of synthetic resin, it is preferable from the viewpoint of aesthetics to integrally form the handrail body by extrusion molding and the sliding member and the grip by injection molding.

(Operation) The handrail main body is a cylindrical body having a slit-shaped opening provided in the side wall along the longitudinal direction. The lifting / lowering assisting tool includes a sliding member and an outer peripheral surface of the sliding member. Since the sliding member is a lump that can be inserted into the cylindrical body of the handrail main body and is larger than the opening of the handrail main body, the sliding member is provided inside the handrail main body. When the sliding member is inserted, the sliding member of the lifting aid does not come off from the inside of the handrail body. Also, since the grip protrudes from the outer peripheral surface of the sliding member, when going up and down stairs,
By grasping the grip protruding from the opening of the handrail body and moving the drive wire as described later, it is possible to move up and down safely.

Further, since a driving wire is connected to the upper end of the sliding member through the handrail main body and another driving wire is connected to the lower end through the handrail main body, the driving device is used. By moving the drive wire, the sliding member can be raised and lowered inside the handrail body.
