[0002]

2. Description of the Related Art A pedestrian bridge with an elevator device is provided with an elevator beside a pedestrian bridge having a stair that extends straight and inclined as disclosed in JP-A-4-333703 and JP-A-63-45763. There is something to install.

[0003]

[Problems to be Solved by the Invention] However, in the conventional pedestrian bridge with an elevator device, a hoistway tower with a built-in elevator device is mounted on the side of the pedestrian bridge. Had to secure. In addition, a conventional elevator apparatus has a drive device having a hoisting machine having a winding drum-type drive mesh wheel for raising and lowering a cage of an elevator, and an entrance and exit of a cage match an entrance and exit of a hoistway. It was necessary to provide a driving device for rotating the basket, and the structure was complicated.

An object of the present invention is to provide a pedestrian bridge with an elevator device, which can raise and lower a cage with a simple structure without securing a place for installing a hoistway tower beside a pedestrian bridge. It is.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a hoistway tower for elevating an elevator cage is provided in a pedestrian bridge connecting at least two points, and an elevator cage is installed in the hoistway tower. A hydraulic cylinder is used for raising and lowering the elevator cage, and a spiral staircase is provided adjacent to the hoistway tower.

[0006]

The user of the stairs can go up the spiral stairs 4, pass the crossing section 5 to the sidewalk on the opposite side, and use the other spiral stairs to cross the road or the like. In addition, a disabled person or the like in a wheelchair rides on the elevator cage 14 in the hoistway tower 10 installed at the center of the spiral staircase 4, climbs up to the crossing section 5, descends at the landing 6, and crosses the crossing section. 5
Passing through the car and getting down on the cage 14 of the other elevator, it is possible to cross a roadway or the like. The elevator user calls the elevator cage 14 with a call button or the like,
The elevator 14 is landed, and the lower entrance door 12 for the hoistway tower and the lower elevator door 15 are engaged and opened, and the elevator 1
4, the lower entrance door 12 and the lower entrance door 15 for the hoistway tower are closed, the elevator 14 rises and stops landing on the landing 6 at the crossing section 5, and the upper entrance door 13 for the hoistway tower 13 The upper and lower entry / exit basket door 16 is engaged and opened, and the user descends to the entry / exit hall 6. The elevator user can go from the platform 6 to the platform 6 on the opposite side using the transfer section 5. Here, descend using the basket 14 of the other elevator,
You can go to the opposite sidewalk.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is an overall plan view of an embodiment showing the installation location of a pedestrian bridge with an elevator device according to the present invention, FIG. 2 is a front view of a pedestrian bridge over one side of the pedestrian bridge, and FIG. 3 is a hoistway tower. FIG.

In FIG. 1, 1 is a roadway, 2 and 3 are sidewalks, and a crossover portion 5 installed above the roadway 1 and a hoistway tower 10 installed adjacent to an end of the crossover portion 5. , 10
And spiral stairs 4, 4 provided adjacent to the hoistway towers 10, 10.

For such a configuration, a person using the stairs climbs the spiral stairs from the sidewalk 2 or 3, passes through the crossing section 5, and descends to the opposite sidewalk 2 or 3 using the other spiral stairs. You can cross roads and the like.
In addition, a disabled person in a wheelchair or a person who cannot use the stairs, such as an elderly person, a sick person, or a woman pushing a baby carriage, can use an elevator cage provided in the hoistway tower 10, 10 from the sidewalk 2 or 3. After the door 12 at the entrance 11 shown in FIG. 2 is fully opened, the rider climbs up to the transfer section 5, gets off the basket at the landings 6, 6, and passes through the transfer section 5 to the opposite sidewalk 2 or 3. It is possible to cross a roadway or the like by getting down on the cage of the other elevator.

Referring to FIG. 3, regarding the elevator apparatus,
This will be described in more detail. In the hoistway tower 10, an elevator cage 14 is installed so as to be able to go up and down.
Have a hoistway tower lower doorway door 12 and a hoistway tower upper doorway door 13 that are fully opened by lowering or ascending at the entrances 11. Further, the elevator basket 14 has a lower getting-in / get-out door 15 and an upper getting-in / get-out door 16 which are lowered or raised and fully opened. In each door, the hoistway tower lower entrance door 12 and the lower getting-in / get-out door 15 engage and open and close, and the hoistway tower upper-entry door 13 and the upper getting-in / get-off door 16 also open and close. It has been made to be. However, the hoistway tower upper entrance door 13 and the lower elevating basket door 16 with respect to the hoistway tower lower entrance door 12 and the lower entrance / exit garage door 15 are engaged so as not to be opened and closed. In other words, when the elevator cage 14 is stopped at the lower side, the hoistway tower lower entrance door 1
2 and the lower elevator door 15 engage and open, but the hoistway tower upper entrance door 13 and the upper elevator door 16 remain closed, and the elevator elevator 14 lands on the upper side. When stopped, the relationship described above is reversed.

[0011] The elevator user is in the elevator cage 1
In the case of using the hoistway tower lower entrance door 12 and engaging the lower hoistway entrance door 12 and lowering the elevator door 15 fully open, the upper end of the hoistway tower lower entrance door 12 and the lower egress door are used. The upper end of the basket door 15 serves as a scaffold 17 when the user gets on and off. The same applies to the case where the upper entry / exit garage door 16 is lowered and fully opened by engaging with the hoistway tower upper entrance door 13. The elevator cage 14 moves up and down by the vertical movement of the rod 19 in the operation of the hydraulic cylinder 18 installed in the pit 20. The hydraulic cylinder 18
Preferably has a multi-stage rod.

The elevator apparatus according to the present invention is configured as described above. For example, on the sidewalk 2, an elevator user calls the elevator cage 14 by using a call button or the like, and the elevator 14 arrives on the floor and moves up and down. The lower entrance / exit door 12 of the road tower and the lower entry / exit garage door 15 are engaged and opened to get into the elevator cab 14. Rises and stops landing on the landing 6 of the crossing section 5, and the hoistway tower upper entrance door 13 and the upper loading / unloading door 16 are engaged and opened, and the user descends on the landing 6. The elevator user can go from the platform 6 to the platform 6 on the sidewalk 3 by using the crossover section 5.
Here, it is possible to descend using the basket 14 of the other elevator and go to the sidewalk 3. When an elevator user crosses from sidewalk 3 to sidewalk 2, it may be crossed in the reverse order.

As shown in FIG. 1, in the first embodiment, the spiral staircase 4 connected to the crossover portion 5 is configured to be symmetrical in the sidewalk 2 and the sidewalk 3, but as shown in FIG. The sidewalk 2 and the sidewalk 3 may be configured asymmetrically.
Further, one embodiment of the present invention is described by using a prism hoistway tower 10 as a square elevator cage 14 and square doors 12, 13, 1.
As described in FIGS. 5 and 16, as shown in FIG. 5, a cylindrical hoistway tower 10, a circular elevator cage 14 and circular doors 12, 13, 15, and 16 may be used. In the first embodiment, the opening and closing of the door is described as being opened and closed by opening and closing.

[0014]

As described above, according to the present invention, an elevator can be installed in a small space without specially securing a place for installing an elevator apparatus on a sidewalk. In addition, even at the corner of the road, it can be installed because there is no linearly extending stairs on the sidewalk. In addition, elevator users and stair users installed on the pedestrian bridge can use a common access bridge, and push the elevator users, that is, the disabled, elderly, sick, and strollers in wheelchairs. Women are available,
Because you will be able to cross the pedestrian bridge freely, you can expand the range of activities.
