Abstract

PURPOSE:To provide a climbing machine which can ascend and descend stairs having landings in a station, carrying a wheel chair or a hand cart on a carrier bed. CONSTITUTION:A stairs climbing machine is composed of a center support wheel 3, a carrier bed 1 having a near-front balance wheel 4, a support wheel running path 5 and a rail 2 having a support wheel traveling path 5, and an U-like groove for the balance wheel. Further, the traveling path is set to be higher than the lower inner surface 6 of the groove by a predetermined height at an inclined part of the stairs, and the traveling path and the lower inner surface of the groove are set to be flush with a horizontal landing so that the balance wheel is held between the groove at the upper and lower parts of the balance wheel. Accordingly, the carrier bed 1 comes up and down by driving a gear 9 meshed with a rack 8 while it is held in a horizontal condition.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stair lift for carrying luggage or a wheelchair and moving up and down stairs at a station with a landing.

[0002]

2. Description of the Related Art A conventional stair lift has a dedicated carrier that moves up and down along a rail installed on a part of the stairs, and a rail fixed to one wall of the stairs supports an L-shaped carrier. The ones that let you move and those that are self-propelled with a caterpillar have been used.

[0003]

The method of installing the rail on a part of the stairs has a drawback that the rail at the landing is an obstacle to stair users, and it is not used in the method in which a dedicated carrier is moved up and down. The problem is how to handle the carriage at the time, and the method of going up and down using the staircase wall has a problem in the strength of the staircase wall because it bears the load on the wall. It was difficult to use the stairs because the size of the stairs and the necessary improvements were large.

[0004]

[Means for Solving the Problem] In order to organize the flow of people on the stairs of a station, an intermediate handrail is often provided in the stairs except for the landing, with a width of about 1 to 2 people.
The present invention uses the rails installed over the entire length of the stairs on the side of the divided narrow wall and the rails installed on the stairs of the middle handrails except for the landing area, and usually under the stairs along these two rails. Raise and lower the electric carrier stored on the floor.

The carrier has a support wheel at the center and a balance wheel at the front side, and the rail has a running path for the support wheel and a U-shaped groove for the balance wheel. The runway is on the outside and the groove is on the inside, and the top and bottom of the balance wheel are sandwiched by the groove. At the slope of the stairs, the runway is set higher than the inner surface of the lower part of the groove by a certain size, and the runway of the slope and the inner surface of the lower part of the groove move horizontally at the floor height of the landing.

In the landing, a rail having only a traveling path is provided on one side, the traveling path is also grooved, and a guide wheel contacting the inner surface of the rail is provided at the tip of the carrier.

Further, one inner surface of the groove is a rack, the balance wheel is an electric gear that meshes with the rack, a roller contacting the other one surface of the groove is provided beside the gear, and a horizontal wheel that lands on the landing is provided. It is provided.

[0008] Further, if necessary, a lower floor of the stairs is provided with a depression whose floor surface is lowered by the height of the deck of the carrier, or an elevating floor which is moved up and down by an electric jack.

[0009]

Embodiments of the present invention will be described below. FIG. 1 is a side view in which a carrier 1 according to the present invention mounts a wheelchair and moves up and down the stairs while keeping the carrier horizontal by rails 2 installed on the stairs.

The carrier has a support wheel 3 in the center and a balance wheel 4 on the front side, and the rail has a running path 5 for the support wheel and a U-shaped groove for the balance wheel. The running path is on the outside and the groove is on the inside, and the top and bottom of the balance wheel are sandwiched by the groove. In the inclined part of the stairs, the traveling path is set higher than the lower inner surface 6 of the groove so that the carriage is horizontal. At the landing, the height of the runway and the lower inner surface of the ditch is the same as the floor of the landing. If the center of gravity of the carrier is in front, the balance wheel contacts the inner surface of the lower side of the groove, and if it is behind, the inner surface of the upper side of the groove, FIG.
The horizontal balance of the carrier is maintained by touching 7).

Normally, handrails are provided in the stairs of stations to separate the flow of people going up and down. The narrow one that is partitioned is wide enough for one or two people to pass through. According to the present invention, rails are laid at the foot of a handrail and on the wall of a narrow stairway that is partitioned, and an electric carrier is moved up and down along the rails. However, there are generally no handrails on the landing, and installing rails here will be an obstacle for pedestrians.

FIG. 2 is a perspective view of a rail installed on the stairs of the present invention in which measures are taken for that purpose. The rail on the handrail side has only the running path 5 on the stairs, and at the landing, the rail is removed and the rail is supported on the floor. The wheels roll. At the same time, the running path is formed in a groove shape, and a guide wheel that contacts the inner surface of the rail is provided at the tip of the carrier so as to maintain the attitude of the carrier at the inclined portion and guide in the traveling direction. This guide wheel 13 is shown in FIG.

In FIG. 3, a drive mechanism is added to the present invention. The inner surface of the lower side of the groove is a rack 8 and an electric gear 9 is engaged therewith to raise and lower the carriage. A roller 10 contacting the inner surface on the upper side of the groove is provided beside the gear, and a horizontal wheel 11 is provided when landing at the landing. The horizontal balance of the carrier is maintained by a gear that meshes with the rack on one side and a roller that contacts the inner surface of the groove on the other side and a horizontal wheel that lands on the landing.

In order not to get in the way of pedestrians when the trolley is placed, the deck height is set to be the same as the steps of the stairs and it is placed on the lower floor of the stairs so that pedestrians can freely pass over it. I have to. However, in this case, the deck surface is higher than the floor surface, and a separate slope is required for loading and unloading in a cart or wheelchair.

FIG. 4 and FIG. 5 show a stair lift with a fixed position of the carriage according to the present invention, which is provided with measures therefor. In FIG. 4, a recess 14 is provided on the lower floor of the stairs, the floor surface of which is lowered by the height of the deck of the carrier. In this case, since a dent is formed when the carriage is moved out, in FIG. 5, an elevating floor 15 that is vertically moved by an electric jack or the like is further provided, and when the carriage is moved out, the lift floor is raised to the floor surface of the lower floor to eliminate the dent. .

On the upper floor of the stairs, by stopping the carriage at a height where the deck surface of the carriage coincides with the floor surface of the upper floor, it is possible to easily get in and out of the cart or wheelchair.

[0017]

According to the present invention, since two rails of a carrier are attached to the stairs of a station, the safety as a stair lift is high, the loading weight is large, and the installation is easy. In addition, since there are no rails that hinder stair users at the landing, and the carrier that is being placed serves as steps and passages on the stairs, the stair lift does not interfere with pedestrian traffic. In addition, the deck of the carrier can be aligned with the floors above and below the stairs, allowing easy entry and exit of wheelchairs and carts.
