Description

  The present invention relates to an elevator cab having an inner wall portion and an outer wall portion arranged to face each other with a space therebetween.

  In a typical elevator, noise is generated by the traveling sound of a car, and the noise increases as the raising / lowering speed of the car increases. Therefore, for example, in an ultra-high speed elevator having a speed of 1000 m / min or more, since the noise is relatively high, a structure for reducing the noise is required. In the conventional apparatus, in order to reduce the sound flowing into the car room, the wall part of the car room is configured by the double wall material of the inner wall member and the outer wall member (see, for example, Patent Document 1).

  Here, a conventional elevator cab will be described. FIG. 6 is a sectional view showing a conventional elevator cab. 7 is a cross-sectional view taken along line VII-VII in FIG. 8 is a cross-sectional view taken along line VIII-VIII in FIG. FIG. 9 is an enlarged view showing the IX portion of FIG. 6 in an enlarged manner. FIG. 6 shows a portion corresponding to a cross section taken along line II-II of FIG. 1 in a conventional cab.

  6-9, the some outer wall member 7 is arrange | positioned on the outer side of the some inner wall member 6 at intervals from the some inner wall member 6, respectively. As shown in FIG. 7, an air layer α is formed between the inner wall member 6 and the outer wall member 7 facing each other. Moreover, the outer wall member 7 has a plate-shaped wall surface forming portion 7a and a pair of projecting portions 7b that are arranged at both ends in the horizontal section of the wall surface forming portion 7a and are connected to other members. A pair of protrusion part 7b protrudes toward the direction orthogonal to the wall surface formation part 7a in the horizontal direction from each of the both ends in the horizontal cross section of the wall surface formation part 7a. The shape of the protrusion part 7b is a horizontal cross-section L-shape.

  Here, the outer wall member 7 is arranged so that the protruding portion 7b protrudes toward the outside of the car chamber 3, that is, the wall surface forming portion 7a is positioned inside the car chamber 3 relative to the protruding portion 7b. The wall surface forming portion 7 a is attached to the lower connection member 10 with bolts 12 and nuts 13. As shown in FIGS. 8 and 9, a sound absorbing material 14 is attached to a surface of the wall surface forming portion 7 a opposite to the inner wall member 6, and a vertical reinforcing material 15 is attached thereto.

  As described above, in the conventional apparatus as shown in FIGS. 6 to 9, the air layer provided between the inner wall member 6 and the outer wall member 7 and the outer wall member 7 are attached to the outer surface of the cage 3. The sound absorbing material 14 reduces the noise transmitted to the car room 3.

JP 2009-119393 A

It is. However, in the conventional apparatus as shown in FIGS. 6 to 9, the wall surface forming portion 7 a is disposed inside the car chamber 3 rather than the protruding portion 7 b, and therefore the air layer α is small by the thickness of the outer wall member 7. The sound insulation effect of noise was not sufficient.

  In addition to this, in the conventional apparatus as shown in FIGS. 6 to 9, the outer wall member 7 is arranged so that the protruding portion 7 b protrudes toward the outside of the car chamber 3, and the car chamber 3 of the outer wall member 7. Since the sound-absorbing material 14 and the longitudinal reinforcing material 15 are provided on the outer surface, the outer surface of the outer wall portion of the cab 3 is uneven. For this reason, the irregularities on the outer surface of the outer wall portion of the car room 3 cause air turbulence when the car is raised and lowered, and noise due to the air turbulence is relatively large, which is also a problem.

  The present invention has been made to solve the above-described problems, and an object thereof is to obtain an elevator cab that can further reduce noise transmitted to the cab.

  According to the elevator cab of the present invention, the plurality of outer wall members are arranged so that the outer surface of the outer wall portion is flat, and each wall surface forming portion of the plurality of outer wall members is more than the respective protruding portion. The outer surface of the outer wall is not uneven, and the air layer becomes larger by the size of the protruding portion of the outer wall member than the conventional device as shown in FIGS. Since the sound insulation effect is improved, the noise transmitted to the car room can be further reduced.
