FIG. 3 is an enlarged view (side view) showing the main part of the car (with car floor displacement) in FIG. 1. A door motor or the like is not shown as an elevator car device.

In FIG. 1, a car 1 includes a car frame 2, a car floor 3, a car room 4, and a car door 5. The car frame 2 is formed by assembling an upper beam 6, a lower beam 7, and a pair of left and right vertical frames 8 into a frame shape. The upper beam 6 extends in the horizontal direction above the cab 4. The lower beam 7 extends in the horizontal direction below the cab 4. The pair of vertical frames 8 extend in the vertical direction between both ends of the upper beam 6 and both ends of the lower beam 7. A car floor support frame 9 on which the car floor 3 can be placed is provided on the lower beam 7 of the car frame 2. The basket car floor 3 is installed on the car floor support frame 9.

A vibration isolator 10 formed of an elastic body is provided between the car floor 3 and the car floor support frame 9. Since the lower surface of the car floor 3 is elastically supported by the vibration isolator 10, the car floor 3 is displaced in a direction approaching the car floor support frame 9 when an in-car load, that is, a load in the car room 4 is applied. The car room 4 is formed in a box shape and is installed on the car floor 3.

The car room 4 has a car door 5 that opens and closes an entrance through which the user enters and exits the hall 11. The car door 5 is suspended from the car door device 12 and is engaged so as to be openable and closable. Below the car door 5, a car sill 13 that guides the opening and closing of the car door 5 is provided. The car sill 13 is fixed to the car floor support frame 9 via a sill receiving beam 14, and extends along the frontage direction of the car 1.

FIG. 2 shows a state where a load in the car room 4 is not applied to the vibration isolator 10, that is, a state where the car floor 3 is in the normal position. FIG. 3 shows a state where the load in the car room 4 is applied to the vibration isolator 10 and the vibration isolator 10 is compressed, that is, the car floor 3 is displaced downward. A blocking plate 15 is provided between the car sill 13 and the car floor 3.

The hinge portion 18 is disposed near the car sill 13 between the fixed portion 16 and the inclined portion 17, and supports the fixed portion 16 and the inclined portion 17 so as to be rotatable with respect to each other. The inclined portion 17 is horizontally arranged when the height of the car sill 13 and the car floor 3 is the same, and when the car floor 3 is displaced downward, an inclined surface descending from the car sill 13 toward the car floor 3 is formed. It is formed. The car floor 3 side of the inclined portion 17 is not fixed and is arranged in contact with the car floor 3.

Next, the operation of the first embodiment configured as described above will be described. When a user or the like gets in or out of the car room 4 or when the user or the like moves in the car room 4, a downwardly biased load is applied to the car floor 3. The load acts in the direction of compressing the vibration isolator 10 via the car floor 3 and is absorbed by the vibration isolator 10 being compressed. Here, since this load does not act on the car floor support frame 9 from the car floor 3, it does not act on a rope (not shown) for suspending the car frame 2. As a result, the vibration generated when the car 1 is traveling or when the user gets on and off can be suppressed, so that the riding comfort is improved. Further, since the car sill 13 is fixed to the car floor support frame 9 via the sill receiving beam 14, it is not affected unless this load acts on the car floor support frame 9. Therefore, even if this load acts on the car floor 3, the car door 5 does not come off from the car sill 13 and a stable opening / closing operation is realized.

On the other hand, when this load is applied to the car floor 3, the car sill 13 is not displaced, but the car floor 3 is displaced downward as the vibration isolator 10 is compressed. In this case, a step is generated between the car sill 13 and the car floor 3. A closing plate 15 is disposed immediately above the step, and when the step occurs, the inclined portion 17 of the closing plate 15 is in contact with the upper surface of the car floor 3 while the fixed portion 16 side is on the hinge portion 18.

The inclined portion 17 is horizontally arranged when the height of the car sill 13 and the car floor 3 is the same, and when the car floor 3 is displaced downward, an inclined surface descending from the car sill 13 toward the car floor 3 is formed. It is formed.

A member that supports the car sill 13 and supports the closing plate 19 is formed on the sill receiving beam 22 fixed to the car floor support frame 9. An elastic body 23 is disposed between the inclined portion 17 and the threshold receiving beam 22 and immediately below the inclined portion 17. The elastic body 23 is always arranged in a compressed state so as to be in close contact with both surfaces of the inclined portion 17 and the threshold receiving beam 22.

Next, the operation of the second embodiment configured as described above will be described. When the position of the car floor 3 is lowered with respect to the car sill 13, a step is generated. A closing plate 19 is disposed immediately above the step, and when the step occurs, the hinge portion 18 and the hinge portion 21 of the inclined portion 17 of the closing plate 19 rotate in the clockwise direction. At this time, the fixing part 16 maintains the horizontal state together with the car sill 13, the fixing part 20 maintains the horizontal state together with the car floor 3, and the inclined part 17 descends from the car sill 13 side toward the car floor 3 side. An inclined surface is formed.

In other words, the step formed when the vibration isolator 10 is compressed and the position of the car floor 3 is lowered with respect to the car sill 13 is closed by the closing plate 19 and is inclined to the inclined portion 17 of the closing plate 19. Therefore, the user or the like moves along the fixed portion 16, the inclined portion 17, and the fixed portion 20 of the closing plate 19 when entering and exiting the landing 11 from the cab 4. At this time, in Embodiment 1, the inclined portion 17 may be deformed when a large load is applied to the closing plate 19 such as a wheel such as a carriage passes. Therefore, the elastic body 23 arranged immediately below the inclined portion 17 receives a large load acting by passing a carriage or the like, thereby preventing the inclined portion 17 from being deformed.

As described above, according to the second embodiment, the closing plate 19 includes one fixed portion 20 that is fixed to the car floor 3, the inclined portion 17 that is disposed between the fixed portion 16 and the fixed portion 20, A hinge portion 21 provided between the fixed portion 20 and the inclined portion 17 and rotatably supporting the fixed portion 20 and the inclined portion 17; and fixed between the inclined portion 17 and the threshold receiving beam 22. By providing the elastic body 23 disposed in close contact with the inclined portion 17, the car 1 that eliminates the step is provided by closing the step formed between the car sill 13 and the car floor 3. can do. Further, since the car floor 3 side is fixed by the fixing portion 20, when a large load is applied to the closing plate 19 due to the passage of a carriage or the like, the closing plate 19 can be prevented from jumping up. When entering / exiting the landing 11 from the inside, it can be easily moved without going over the step and the closing plate 19. Further, when a large load is applied to the blocking plate 19 due to the passage of a carriage or the like, the car 1 that can prevent the inclined portion 17 from being deformed by the sill receiving beam 22 receiving the load via the elastic body 23 is provided. be able to.

Embodiment 3 FIG.
6 to 8 illustrate an elevator car according to Embodiment 3 of the present invention. FIG. 6 is a side view showing the main part of the car (no car floor displacement) in FIG. 1, and FIG. It is a side view which shows the principal part of 1 riding car (with a car floor displacement). FIG. 8 is an enlarged view (plan view) showing a main part of the car of FIG. The elevator car according to the third embodiment of the present invention is different in the structure of the blocking means for eliminating the step generated between the car sill and the car floor, and the same symbols are added to the other similar parts and the description is omitted. To do.

FIG. 6 shows a state where the load in the car room 4 is not applied to the vibration isolator 10, that is, the car floor 3 is in the normal position. FIG. 7 shows a state where the load in the car room 4 is applied to the vibration isolator 10 and the vibration isolator 10 is compressed, that is, the car floor 3 is displaced downward. Between the car sill 13 and the car floor 3, a pair of a closing body 24 and a closing body 25 are provided.

In FIG. 8, the closing body 24 is provided on the side surface of the car floor 3 disposed to face the car sill 13, and is provided with a comb portion 26 having a horizontal surface formed in a comb shape. The obstruction body 25 is provided on a side surface of the car sill 13 disposed to face the obstruction body 24, can be engaged with the comb portion 26, and has an inclined surface that descends from the car sill 13 side toward the car floor 3. A notch portion 27 is provided.

Next, the operation of the third embodiment configured as described above will be described. When the car floor 3 is in the normal position, the position of the upper end surface of the comb portion 26 is arranged at substantially the same height as the position of the upper end surface of the car sill 13. At this time, the comb portions 26 and the cutout portions 27 are alternately arranged and engaged with each other so as to be movable up and down, and when viewed from the horizontal direction, the inclined surface of the cutout portion 27 substantially overlaps the comb portion 26. Are arranged. That is, when viewed from the horizontal direction, the inclined surface of the notch 27 is not substantially exposed when viewed from the upper end surface of the car sill 13. In this state, there is no step between the car sill 13 and the car floor 3 and the inclined surface of the notch 27 is not exposed. , You can easily get in and out of the hall 11 from the car room 4.

When the position of the car floor 3 is lowered with respect to the car sill 13, the comb portion 26 is also displaced in conjunction with the car floor 3 in the downward direction. On the other hand, the cutout portion 27 is not affected by the displacement of the comb portion 26, and thus the position thereof is maintained. That is, when the comb part 26 is displaced downward, the inclined surface of the notch part 27 is relatively exposed. At this time, when viewed from the horizontal direction, when the horizontal plane of the comb portion 26 is displaced downward, the horizontal plane gradually overlaps the inclined surface of the cutout portion 27 and the cutout portion 27 of the closing body 25 is relatively exposed. Therefore, a downward inclined surface is formed from the car sill 13 side toward the car floor 3 side.

As a result, when the vibration isolator 10 is compressed and the position of the car floor 3 is lowered with respect to the car sill 13, there is no step, and instead, the car 27 is notched by the notch 27 of the closing body 24. Since a downward inclined surface is formed from the side of the sill 13 toward the side of the car floor 3, a user or the like does not go along the inclined surface of the notch 27 when entering or exiting the landing 11 from the inside of the car room 4. Move easily.

As described above, according to the third embodiment, the pair of closing bodies 24 that are alternately arranged in the horizontal direction and engage with each other so as to be movable up and down are provided on the side where the closing body 24 is engaged. A comb portion 26 formed in a comb shape and a notch portion 27 engageable with the comb portion 26 on the other side are provided. The comb portion 26 is provided on the car floor 3, and the notch portion 27 is provided on the car sill 13. The notch 27 is provided with an inclined surface descending from the car sill 13 side toward the car floor 3, and the comb portion 26 has a horizontal surface that can be alternately engaged with the inclined surface, whereby the car sill is provided. When the position of the car floor 3 is lowered with respect to 13, an inclined surface is formed between the car threshold 13 and the car floor 3 instead of a step. Thereby, the car 1 that eliminates the step can be provided. Further, since the closing body 24 and the closing body 25 do not need to be formed in a plate shape, even when a large load is applied due to the passage of a carriage or the like, it is easy to make the shape difficult to deform without using an elastic body or the like. It becomes. Furthermore, since the structures of the closing body 24 and the closing body 25 are simple, failure is unlikely to occur and maintenance is facilitated.

In the first embodiment, the inclined portion 17 of the closing plate 15 is disposed in contact with the car floor 3, but a twist spring or the like is provided on the hinge portion 18 so that the inclined portion 17 biases the car floor 3. And may be configured to be pressed. Thereby, when a user etc. pass the obstruction board 15, it can be used stably by suppressing the jumping of the inclined part 17.

In the third embodiment, the notch 27 is provided on the side surface of the car sill 13, but the same operation and effect can be obtained even if it is configured to be directly fixed to the sill receiving beam 14 or the car floor support frame 9. Needless to say.
