[0088] The first weight sheave (1223a) and the second weight sheave (1223b) can be arranged on both sides based on the center of the weight (1300).

[0089] Additionally, ropes supported by some of the plurality of sheaves included in the driving sheave (1331) may be supported by the first weight sheave (1223a), and ropes supported by the remaining of the plurality of sheaves may be supported by the second weight sheave (1223b).

[0090] Meanwhile, the driving motor (1210) can be implemented as an integrated driving unit in which a driving sheave (1331) is combined.

[0091] With respect to the direction of travel of the rope (1230), an elevator car (1100) may be positioned on one side of a drive sheave (1221) coupled to a drive motor (1210), and a weight (1300) may be positioned on the other side.

[0093] The weight side rope end (1410) is supported by the weight sheave (1223) and the extended rope (1230) is connected and fixed.

[0094] The weight side rope end (1410) includes a first weight side rope end (1411) and a second weight side rope end (1412).

[0095] The first weight-side rope end (1411) may be arranged to face the first weight sheave (1223a), and the second weight-side rope end (1412) may be arranged to face the second weight sheave (1223b).

[0096] The first weight-side rope end (1411) may be uniaxially arranged with respect to a tangent line (C3) of the first weight sheave (1223a) in the outward direction from the center of the weight (1300), and the second weight-side rope end (1412) may be uniaxially arranged with respect to a tangent line (C4) of the second weight sheave (1223b) in the outward direction from the center of the weight (1300).

[0097] Additionally, a car side rope end (1420) may be placed on one side of the elevator shaft, and a weight side rope end (1410) may be placed on the other side.

[0098] The side rope end (1420) is supported by the kashib (1222) and the extended rope is joined and fixed.

[0099] The car side rope end (1420) may be arranged uniaxially with respect to the tangent line (C1) of the first car side (1222a) in the outward direction from the center of the elevator car (1100), and the hoistway side tangent line (C5) of the driving sheave (1221) may be arranged coaxially with the tangent line (C2) of the second car side (1222b) in the outward direction from the center of the elevator car (1100).

[0100] The rope (1230) includes a first rope (1231) and a second rope (1232).

[0101] The first rope (1231) is connected and fixed to the first weight-side rope end (1411), and the second rope (1232) is connected and fixed to the second weight-side rope end (1412).

[0102] The first rope (1231) is supported on the first weight sheave (1223a), and the second rope (1232) is supported on the second weight sheave (1223b).

[0104] The first rope (1231) and the second rope (1232), which are supported by the first weight sheave (1223a) and the second weight sheave (1223b), respectively, are supported by the driving sheave (1221), supported by the second cashew (1222b) and the first cashew (1222a), and then fixed to the car side rope end (1420).

[0105] The drive sheave (1221) and the car side rope end (1420) may be arranged to face the center of the elevator car (1100) when the elevator car (1100) is raised to the top so that one side is positioned on the roof.

[0106] This is to raise and lower the elevator car (1100) while maintaining maximum stability.

[0107] The elevator car (1100) is equipped with air mobility and can be formed to have a volume greater than a certain size to enable stable ascent and descent.

[0108] The height (D1) of the elevator car (1100) can be formed to be greater than the distance (D2) from the roof to the driving sheave (1221).

[0109] Accordingly, even when the elevator car (1100) is raised to the rooftop, the elevator car (1100) can be raised and lowered stably.

[0110] The height (D1) of the elevator car (1100) can be set to twice the size of the distance (D2) between the rooftop and the driving sheave.

[0111] Meanwhile, the elevator system may further include a stopper and a position adjustment sensor to ensure that the elevator car (1100) stops at the correct position on the roof.

[0112] A guide rail (G) for guiding the movement of an elevator car (1100) is installed in a hoistway, and a guide shoe (not shown) corresponding to the guide rail (G) can be coupled to the elevator car (1100).

[0113] In addition, in order to guide the stable movement of the elevator car (1100), two guide rails are installed on each side of the elevator shaft, and correspondingly, two guide shoes can be combined on each side of the elevator car (1100).

[0114] The elevator system according to the present invention can be applied to an elevator of mobility including not only urban air mobility but also air mobility capable of vertical takeoff and landing.

[0115] An aviation mobility elevator system (1000) according to one embodiment of the present invention is configured as described above, and an elevator car (1100) moves along an elevator shaft facing a pit (P), a hangar (H1, H2), and a machine room (M), and when raised to the upper part, can be positioned on one side of a rooftop (R), which is a takeoff and landing pad.

[0116]

[0117] Figure 4 is a schematic first usage state diagram of an elevator system according to a first embodiment of the present invention.

[0118] As shown, the elevator car (1100) of the air mobility elevator system (1000) is shown with the air mobility (100) mounted thereon and lowered to the bottom of the elevator shaft.

[0119] More specifically, one end of the rope (1230) is connected to the car side rope end (1420), and the other end of the rope (1230) is connected to the weight side rope end (1410), and is sequentially supported by the car side (1222), the drive sheave (1221), and the weight sheave (1223).

[0120] That is, the drive motor (1210) rotates the drive sheave (1221) to one side, so that the rope (1230) is provided to the car side rope end (1420), and the elevator car (1100) moves to the lower part of the hoistway while the rope (1230) is supported by the sheave (1222).

[0121] Additionally, as the rope (1230) moves toward the cassette (1222), the weight (1300) to which the weight sheave (1223) is coupled moves to the upper part of the elevator shaft.

[0122]

[0123] Figure 5 is a schematic second usage state diagram of an elevator system according to the first embodiment of the present invention.

[0124] As shown, the elevator car (1100) of the aviation mobility elevator system (1000) is shown in a state where the aviation mobility (100) is mounted and raised to the upper part of the elevator shaft.

[0125] When the drive motor (1210) rotates the drive sheave (1221) to the other side, the rope (1230) is provided to the weight side rope end (1410) side, and the elevator car (1100) is moved to the upper part of the hoistway while being supported by the sheave (1222).

[0126] Additionally, as the rope (1230) moves toward the weight side rope end (1410), the weight (1300) to which the weight sheave (1223) is coupled moves to the lower part of the elevator shaft.

[0127] Additionally, the elevator car (1100) can be positioned on the same plane as the rooftop (R).

[0128]

[0134] The air mobility (100) can be moved to the landing pad (12), hangar (13) and takeoff pad (11) by an elevator system (1000) and can be parked in the hangar (P).

[0135] The elevator car (1100) of the elevator system (1000) can move to the rooftop (R) of the vertiport, which is the upper part of the vertiport (10), and stability is ensured because the driving module (1200, see FIG. 5) does not protrude from the rooftop (R).
