1, the traveling rail 92 is bent in an L shape. In the U-type of FIG. 29, the traveling rail 92 is bent in a U shape along the stairs 91 which is three-dimensionally bent in a U shape.

In these chair-type lifting devices, since the traveling rail 92 is directly installed on the stairs 91, the traveling rail 92 narrows the effective width dimension of the stairs 91, so that a normal stair user can travel. The rails 92 and the chairs 93 could sometimes get in the way.

Therefore, without narrowing the effective width of the stairs,
A suspension type stair climbing device that is less intrusive to stair users is disclosed in, for example, Japanese Utility Model Publication No. 5-94046 (utility model registration No. 2599224) and Japanese Utility Model Publication 5-8117.
No. 2 and Japanese Patent Application Laid-Open No. 11-115752.

For example, as shown in FIG. 30, the device disclosed in Japanese Patent Application Laid-Open No. 11-115752 is arranged above the stairs 95, and has a guide rail 96 having an inclined rail portion 96a and a guide rail 96. Traveling carriage 97 that travels in a traveling manner, and a boarding device 98 that is suspended downward from traveling carriage 97

In this stair climbing device, the guide rail 96 is arranged near the ceiling of the stairway away from the stairs 95, so that the effective width of the stairs is not narrowed and it is difficult for the stairs users to get in the way. .

[0006]

However, the stair climbing device of the above-mentioned publication has, for example, a two-story building with a straight traveling section and an inclined traveling section between the first floor and the second floor, but it is planar. It was only intended to be run straight, and it was not planned to run continuously between each floor of buildings on the third floor and above. For this reason, it was not possible to install the stair climbing device on the stairs of a building with three or more floors to continuously raise and lower the riding equipment 98. In particular, there has been no stair climbing device that can be installed in the staircase 100 of an apartment house on the third floor or above as shown in FIG. 31, including the stair climbing devices of the above publications.

In addition, in the staircase 100, a plurality of landings 1
A stairway passage 104 is provided which includes 01 and 102 and a plurality of stairs 103 and is three-dimensionally connected in a zigzag manner in the vertical direction. The stairs 103 between the two landings 101 and 102 are arranged in such a manner that the inclination direction is reversed with the landings 101 and 102 as boundaries. For this reason, in order to raise and lower a person between the third floor and higher floors by providing the hanging stair climbing device in the staircase 100, the first floor 101 and the second floor 1
01, a different stair climbing device must be provided between the upper and lower lands 101, 102 such as between the second-floor landing 101 and the third-floor landing 101. You will need it. A person who uses these devices must change the stair climbing device for each landing 101, 102.

On the other hand, in order to eliminate multiple transfers,
It is conceivable to continuously run the boarding gear 98 in the staircase 100, but in this case, the guide rails must be continuously arranged along the stairway passages 104 that three-dimensionally extend in a zigzag. Therefore, in each landing 101, there may be a problem of interference between the guide rail provided in the stairway passage 104 and the door 105, and the placement of the guide rail in the stairway passage 104 becomes a problem.

Further, in order to allow the traveling carriage to travel stably along the guide rails which are three-dimensionally connected in a zigzag manner, the traveling drive device also requires a specific device. Particularly, in the corner of the stairway, the guide rail is bent into a U-shape three-dimensionally with a relatively large bending rate. Therefore, in order to stably drive the traveling carriage along the guide rail, a specific configuration of the traveling drive device corresponding to the corner of the guide rail becomes a problem. Here, as the traveling drive device, it is conceivable to use a chain and a sprocket in addition to using a rack and a pinion like the stair climbing device of the above publication. However, in these cases, the meshing surfaces of the chain and the rack must theoretically be arranged three-dimensionally in accordance with the bending of the guide rail. For this reason, not only the structure of the chain and the rack becomes complicated, but also the structure for continuously engaging the sprocket and the pinion with the chain and the rack becomes complicated. On the other hand, it is conceivable to drive the pulley provided on the traveling carriage along the guide rail, but in this case as well,
The problem is how to run the pulley at the corner of the guide rail, and in some cases, the pulley may fall off the guide rail.

The present invention has been made in view of the above circumstances, and a first object thereof is to make it possible to arbitrarily continuously elevate between stairs in a staircase of a building without narrowing the effective width of stairs.

Never stagnant. If the electric motor 17 is stopped when the traveling vehicle 4 reaches an arbitrary position, the traveling vehicle 4 stops together with the wire 15 and the boarding platform 5 stops at the same position. Therefore, the traveling carriage 4 can be driven with a relatively simple structure by combining the plurality of guide pulleys 14 and the wires 15 without using a rack and pinion having a complicated structure or a chain and a sprocket. Therefore, compared to the case where a rack and a pinion or a chain and a sprocket are used, the design and construction of the stair climbing device can be simplified, and the platform 5 is stabilized along the stairway 2 of the staircase 1. And it can be raised and lowered smoothly.

In particular, according to the stair climbing device of this embodiment, the wire 15 is endlessly routed between each guide pulley 14 and the drive pulley 18, and both ends of the wire 15 are fixed to the traveling carriage 4. . Therefore, the drive pulley 1
In 8, the wire 15 only goes around in a loop,
The wire 15 is not wound around the pulley 18.
Therefore, it is not necessary to provide a space for winding the wire 15 around the drive pulley 18, and the traveling drive source 16 can be made compact.

According to the stair climbing device of this embodiment,
In the straight portions 3b and 3c of the guide rail 3, in the traveling carriage 4, the pair of traveling rollers 31A and 31B travel on the guide rail 3 in the same direction together with the corresponding support frames 32A and 32B. As a result, the traveling carriage 4 along with the boarding platform 5 smoothly moves straight up and down along the linear portions 3b and 3c on the guide rail 3. On the other hand, in the traveling vehicle 4, the traveling rollers 31A and 31B rotate independently with respect to the casing 34 due to the supporting structure including the casing 34 and the supporting frames 32A and 32B. Therefore, at the corner of the guide rail 3, the traveling rollers 31A and 31B are
Is allowed to travel on the guide rail 3 in different directions according to the bend of the guide rail 3. As a result, the traveling carriage 4 continuously travels in the corners of the guide rails 3 without interruption, and the boarding platform 5 can smoothly turn while turning the corners of the guide rails 3. As a result, the boarding platform 5 can be stably and smoothly moved up and down regardless of the straight section or the corner of the stairway 2.

According to the stair climbing device of this embodiment,
When the boarding platform 5 moves up and down along the stairway 2,
The steady rest 71 provided at the position moves along the auxiliary rail 13 while engaging with the auxiliary rail 13. Therefore, swinging of the boarding platform 5 in the traveling direction of the traveling vehicle 4, that is, in a direction intersecting with the ascending / descending direction of the boarding platform 5 is restricted, and the boarding platform 5 does not roll sideways with respect to the traveling direction of the boarding platform 5. It will go up and down along. For this reason, the boarding platform 5 can be moved up and down along the stairway 2 more stably and smoothly because there is no rolling in the traveling direction.
Further, in this embodiment, since the auxiliary rail 13 is located at a height about the waist of a person, the staircase user may use the auxiliary rail 13 as a handrail when the platform 5 is not used. it can.

According to the stair climbing device of this embodiment,
By retracting the rod 63a of the electric cylinder 63 provided on the boarding platform 5 at the landing position of each floor 6 or the like, the footrest 55, the seat 56, and the armrest 57 of the platform 5 are lowered to near the floor. As a result, a person can easily get on the boarding platform 5 simply by moving horizontally. After that, by extending the rod 63a of the electric cylinder 63, the footrest 55, the seat 56, and the armrest 57 are lifted from the floor surface so that they do not interfere with the floor surface or the stairs 8. Therefore, a person can easily get on and off the boarding platform 5 at a predetermined boarding / alighting position. As a result, even an elderly person or a physically handicapped person can get on and off the boarding platform 5 with peace of mind. Further, in this embodiment, the footrest 55 and the seat 56
Also, an armrest 57 is provided so as to be foldable with respect to the elevating frame 53. Therefore, when the boarding platform 5 is not used, the members 55 to 57 can be folded so that the stairs user can stand by without getting in the way.

The present invention is not limited to the above-described embodiment, but may be implemented by appropriately modifying a part of the configuration without departing from the spirit of the invention.

For example, in the above-described embodiment, the guide rail 3 is fixed to the side surface of the partition wall 10 via the bracket 21, but the guide rail may be fixed to the ceiling of the stairway via the bracket.
