The gist is that the turntable and the flange are formed so as to be flush with the floor of the elevator car, and are housed in a frame with a flange that is installed so as to be dropped onto the floor of the car.

In the configuration of the second invention, a turn device with a turntable is installed in a pit below the elevator room, and the turn device includes:
When the elevator car descends to the first floor and stops, the gist is that the wheelchair is turned by pushing up a rotating plate provided on the floor of the elevator car.

According to a third aspect of the present invention, a turn device with a turntable for turning a wheelchair is installed on a floor of a building in front of a door of an elevator room, and the turn device is mounted on a floor with a flange so as to be dropped on the floor of the building. The gist is that the turntable and the flange form the same plane as the floor of the building.

According to the first aspect of the present invention, the turn device includes:
By riding the wheelchair on the turntable, the direction of the wheelchair can be easily changed even in a narrow elevator car, and the turning operation of the wheelchair user is unnecessary. Since the turn device moves up and down with the elevator car,
The turning device can be used not only while the elevator car is stopped on each floor, but also while the elevator car is moving. Also, when the turn device is out of order,
By removing the entire frame with flange from the floor of the elevator car and replacing the set, the time required for restoration can be minimized.

According to the configuration of the second invention, since the turn device is installed in the pit below the elevator room, the turn device can be used when the elevator car stops on the first floor, and the weight of the turn device is raised and lowered. Does not load the car drive mechanism. In addition, the elevator can be raised to expose the turn device, and the turn device can be easily replaced.

According to the configuration of the third invention, since the turn device is installed on the floor in front of the door of the elevator room, the wheelchair can be turned before entering the elevator car, and the wheelchair retreating operation required for boarding can be performed. Requires the least. In this case, also in this case, the turn device can be removed and replaced with the frame from the floor of the building as in the first invention.

Embodiments Hereinafter, embodiments will be described with reference to the drawings.

The home elevator mainly includes an elevator car 20 and a turn device 30 mounted on the elevator car 20 (first example).
Figure). However, the elevator car 20 is suspended in the tower 10 via the upper winch 11 so as to be vertically movable.

Tower 10 is a foundation F installed under the floor of a two-story wooden building.
It is formed by assembling a steel frame on top. Tower 10
Inside, the top machine room 10a and the middle lifting room 10s
And the lowermost pit 10p are formed. Machine room 10a
Protrudes from the ceiling surface C of the second floor to the attic side, and a winch 11 is disposed inside. On the other hand, pit 10p
Surrounded by the foundation F under the floor, dampers 12 for absorbing shock,
12 are located inside. Also, the lifting room 10s in the middle
Communicates from floor F1 on the first floor to ceiling C on the second floor. In addition, doors D1 and D2 are stored for each floor on the wall of the building having an entrance to the elevator room 10s, and the doors D1 and D2 can open and close the front of the elevator room 10s.

The elevator car 20 includes a ceiling plate 21, three side plates 22, 22.
It is a box-shaped body composed of a door (not shown) on the doors D1 and D2 side and a bottom plate 23, and is suspended by the winch 11 of the machine room 10a,
It can be freely moved up and down by button operation. The bottom plate 23 forms the floor of the elevator car 20.

The turn device 30 is configured by combining a fixed base 31, a rotary drum 32, and a turntable 33 (second
Figure). The turn device 30 is housed in a bottomed frame 34 having a flange 34a at the top, and is attached to the bottom plate 23 of the elevator car 20 via the frame 34. The frame 34 is installed so as to drop the whole into the opening of the bottom plate 23, and the flange 34a, together with the upper surface of the turntable 33, forms the same plane as the floor surface of the elevator car 20 formed by the bottom plate 23. . The turn device 30 incorporates a drive motor (not shown), and has a mechanism in which the rotating drum 32 and the turntable 33 rotate with respect to the fixed base 31. Therefore, the wheelchair CH on the turntable 33 can be turned on the spot (in the direction of the arrow in FIG. 3, a solid line and a two-dot chain line).

Such a home elevator is, for example, a wheelchair CH
Of the first floor from the first floor to the second floor (No. 3
(See FIG.), The wheelchair CH can be moved forward to get on the elevator car 20 and be placed on the turn device 30 (solid line in the figure). Here, if the turn device 30 is operated, the wheelchair CH can be easily turned in the narrow elevator car 20. On the second floor side, since the direction of the wheelchair CH has already changed, the wheelchair CH is turned. There is no need to move out of the elevator car 20 only by moving forward (two-dot chain line in the figure).

Since the turn device 30 moves up and down together with the elevator car 20, the turn device 30 may turn when it reaches the second floor, or may turn while ascending. The same applies to the case of going from the second floor to the first floor.

Another Embodiment The turn device 30 can be installed in the pit 10p (FIG. 4). The turn device 30 is fixed on a central pedestal Fb integral with the foundation F forming the pit 10p.

A rotating plate 23b is provided at the center of the bottom plate 23 of the elevator car 20. The rotating plate 23b has a disk shape, and its outer peripheral portion has an annular flange 23a of a fitting structure fixed to the bottom plate 23 side.
And it is rotatable by being pushed up from below. The height of the pedestal Fb is set such that the turntable 33 slightly pushes up the rotary plate 23b from below when the elevator car 20 descends and the bottom plate 23 stops so as to match the floor level FL. Adjusted (four-dot chain line).

When the elevator 20 stops at the first floor, the home elevator can push up the rotating plate 23b of the bottom plate 23 by the turn device 30 to be driven to rotate, so that the direction of the wheelchair CH can be changed on the first floor side, If you get in from the second floor, you can use it when you go to the first floor. By installing the turn device 30 in the pit 10p, the weight of the elevator car 20 can be reduced, and the load on the winch 11 that drives the elevator car 20 can be reduced.

The turn device 30 can be installed on the floors F1, F2 of the building in front of the doors D1, D2 of the lift room 10s on each floor (FIG. 5).
Before getting into the elevator car 20 or after getting off the elevator car 20, the direction of the wheelchair CH can be changed using the turn device 30, so even if there is not enough space in front of the doors D1, D2. , The wheelchair CH can be easily turned. Further, since it is not necessary to mount the turn device 30 on the elevator car 20, the present invention can be implemented even when a space for turning the wheelchair CH in the elevator car 20 is not available. However, any one of the first floor and the second floor may be omitted from the turn device 30, and there is not much inconvenience in use. In FIG. 5, the door 24 of the elevator car 20 is also shown.

In the above description, the home elevator is not limited to a building having two floors above the ground, and can be similarly installed in a building having another floor or a building having three or more floors.

Effects of the Invention As described above, according to the first invention of the present application, by mounting a turn device for turning a wheelchair on an elevator car, a user of the wheelchair can make a turn when getting on and off the elevator car. Since the wheelchair can be turned using the device, it is not necessary to turn the wheelchair in a difficult place in a narrow place, and the living environment can be greatly improved.In addition, the turn device is housed in a frame with a flange. Therefore, in the event of failure or malfunction, there is an excellent effect that the frame can be easily replaced and the time required for recovery can be minimized.

According to the second aspect of the present invention, since the turn device is installed in the pit below the elevator room, the load on the drive mechanism for driving the elevator car can be reduced, and the turn device can be lifted by raising the elevator car. It can be replaced within the shortest time.
