1 is a plan view showing a car of an underslang type elevator apparatus according to Embodiment 1 of the present invention, and FIG. 2 is a side view showing the car of FIG. In the figure, a car 1 has a car floor 2, a car room 3, a pair of car doors 4, a door support guide 5 and a car sill 6. The car room 3 is provided on the car floor 2. A car doorway 3 a is provided on the front surface of the car room 3. The car entrance 3 a is opened and closed by a car door 4.

The door support guide 5 is disposed above the car door 4. The car door 4 is supported by a door support guide 5. The door support guide 5 has a girder fixed to the upper part of the car room 3 and a door rail provided on the girder and guiding the opening / closing operation of the car door 4. The car door 4 is supported by being suspended from a door rail. Further, a door motor (not shown) for driving the car door 4 is mounted on the upper portion of the car 1.

The car door device includes a car door 4, a door support guide 5, a car sill 6, and a door motor. A landing door device (not shown) is provided between the landing on each floor and the hoistway so as to face the car door device when the car 1 is landed.

The car sill 6 is arranged below the car door 4 and guides the lower end of the car door 4 when the car door 4 is opened and closed. For this reason, the car sill 6 is provided over the entire movement range of the car door 4. A sill groove (not shown) is provided on the upper surface of the car sill 6. A plurality of door legs (not shown) to be inserted into the sill grooves are attached to the lower end of the car door 4.

Further, the car sill 6 is attached to the car floor 2 via a sill receiving beam 6a. The sill receiving beam 6a is continuously provided in a range substantially equal to the range in the width direction of the car entrance 3a, and forms a floor surface of the car entrance 3a.

The car room 3 is disposed on the right side of the car entrance 3a when viewed from the landing side, and the plurality of first side wall panels 7, the plurality of second side wall panels 8 facing the first side wall panel 7. A first entrance / exit side panel 9, a second entrance / exit side panel 10 disposed on the left side of the car entrance / exit 3 a when viewed from the landing side, and a plurality of rear wall panels 11 facing the entrance /

exit side panels

9, 10. Have. The entrance /

exit side panels

9 and 10 form a landing side wall surface 3 b of the cab 3.

On both sides of the car doorway 3a, there are provided first and

second pillar portions

9a, 10a protruding from the landing side wall surface 3b to the landing side. The

column portions

9a and 10a form left and right side wall surfaces of the car doorway 3a. Further, in this example, the

column portions

9a and 10a are formed to be bent at the car entrance / exit 3a side end portions of the entrance /

exit side panels

9 and 10. Furthermore, the door support guide part 5 is being fixed to the upper end part of

pillar part

9a, 10a.

A pair of suspended

vehicle beams

12 a and 12 b are fixed to the lower part of the car floor 2. The

suspension vehicle beams

12a and 12b are arranged in parallel with a space therebetween. Further, the

suspension vehicle beams

12a and 12b are disposed so as to obliquely intersect the center line in the width direction of the car 1 (vertical direction in FIG. 1) when the car 1 is viewed from directly above.

Between the

suspension car beams

12a and 12b, rotatable first and second

car suspension cars

13 and 14 are attached. The rotation axes of the

car suspension wheels

13 and 14 are parallel and horizontal to each other. Further, the

car suspension wheels

13 and 14 and the

suspension vehicle beams

12a and 12b are grouped as an assembly.

A suspension means 15 for suspending the car 1 in the hoistway is wound around the

car suspension wheels

13 and 14. As the suspension means 15, for example, a plurality of ropes or a plurality of belts are used. The suspension means 15 crosses under the car 1 so as to obliquely intersect the center line in the width direction of the car 1 when the car 1 is viewed from directly above.

A surface obtained by extending an end surface of the car sill 6 on the side of the car room 3 in the vertical direction outside the first pillar 9a (below the pillar 9a in FIG. 1) with respect to the car entrance 3a, and a landing side wall 3b A suspension means passage space 16 that is continuous in the vertical direction is formed therebetween.

A portion of the suspension means 15 that extends upward from the first car suspension vehicle 13 is passed through the suspension means passage space 16. Therefore, when the car 1 is viewed from directly above, one end portion of the car suspension wheel 13 is located in the suspension means passage space 16, and the remaining part of the car suspension wheel 13 overlaps with the car room 3. .

The end of the suspension means passage space 16 in the width direction of the car 1 opposite to the first column part 9 a is connected to the space in the hoistway around the car 1. That is, the suspension means passage space 16 is an open space having one side surface opened to the hoistway space when viewed from directly above. In this example, the side surface of the suspension means passage space 16 is continuously open to the hoistway space over the entire length in the vertical direction.

Further, when the car 1 is viewed from directly above, the boundary of the suspension means passage space 16 is formed by the first entrance / exit side panel 9, the door support guide part 5, the car sill 6, and the first column part 9a.
