  • the control device 14 comprises a control board 46 and a control board fixture 48.
  • the control board 46 is a small and thin control board
  • the control board fixture 48 is a thin L-shaped item whose two faces cross each other at 90 degrees.
  • the control board 46 is fixed by the control board fixture 48.
  • the bottom portion of the control board fixture 48 is embedded underneath the upper floor plate 26. and installed over the machinery room floor plate 22.
  • a cable for transmitting rotation and stop signals from the control device 14 to the hoisting machine 12 is also laid underneath the upper floorplate 26.
  • the upper floorplate 26 is installed over the machinery bases 24, there is void space between the upper floor plate 26 and the machinery room floor plate 22 where the machinery bases 24 is not arranged, because the machinery bases 24 are two beams disposed over the machinery room floor plate 22.
  • the control device 14 is installed, with the lower portion of the control board fixture 48 of the control device 14 and a cable 50 connected to the lower portion of the control board 46 being embedded underneath the upper floor plate 26.
  • the machinery bases 24 are composed of beams having a shape formed by thinning both end parts of conventional beams.
  • the machinery base middle part 32 of the machinery bases 24 supporting the hoisting machine 12 is formed somewhat thicker than the machinery base ends 30.
  • This thicker machinery base middle part 32 is fitted into the opening 30 of the machinery room floor plate 22.
  • the machinery room floor 4 can be formed generally thin to enable a larger available space to be secured in the machinery room 6. Therefore, safety check and repair operations in the machinery room 6 can be accomplished more efficiently to reduce the length of time taken for maintenance, resulting in improved elevator servicing.
  • the machinery base middle part 32 on which the hoisting machine 12 is installed is subject to the greatest force due to the up and down movements of the cage 8 and the balance weight 10. Therefore, the greater thickness of the part on which the hoisting machine or some other load are installed makes it possible to provide sufficient strength to the machinery bases 24 to support the hoisting machine 12.
  • the upper floor plate 26 prevents the machinery bases 24 from protruding out of the surface of the machinery room floor 4. Therefore, the machinery room floor 4 is flat where there is no equipment installed, such as the hoisting machine 12 or the control device 14. This makes possible suppressing the level gap within the machinery room 6 when entering or leaving the machinery room through the door 16 and ensuring adequate footholds for maintenance personnel working in the machinery room 6 for safety check or repair of the hoisting machine 12 or the control device 14, enabling the personnel to accomplish the work more efficiently and reduce the length of time taken for maintenance, resulting in improved elevator servicing.
  • the lower portion of the control board fixture 42 of the control device 14 and the cable 50 are embedded underneath the upper floor plate 26 and installed by utilizing the void space between the upper floor plate 26 and the machinery room floor plate 22. Therefore, as the relatively tall control device 14 can be arranged in a low position away from the machinery bases 24, the control device 14 can be prevented from adding to the height of the machinery room 6.
  • control device 14 can be installed in a stable state without having to reduce its overall thickness and sacrifice part of its width for parts needed for its installation.
  • control device 14 is arranged within the machinery room 6, the invention is not limited to this configuration, but the control device 14 may as well be provided outside the elevator apparatus. Even if the control device is installed within the machinery room 6, the shape of the control device need not be shaped as described above, but may have some other shape. Furthermore, the control device need not be fitted into the machinery room floor 4, but may instead be installed on the top face of the machinery room floor 4 as according to the prior art.
  • the machinery room floor plate 22 has the square opening 30, and by fitting the machinery base middle part 42 into this opening, the machinery bases 24 are fitted into the machinery room floor plate 22.
  • the opening need not be square, but two rectangular openings, longer laterally, matching the shape of the machinery base middle part 42 may as well be arranged in parallel. In this case, however, additional rope passing holes would be needed.
  • the method of fitting the machinery bases 24 into the machinery room floor plate 22 is not limited to what was described above.
  • each of the machinery bases 24 is provided with the thicker machinery room middle part 32 to be arranged in the central part of the machinery room 6, and here is arranged the hoisting machine 12.
  • the shape of the machinery bases 24 is not limited to this, but it is only required that the part where the hoisting machine 12 is to be installed is formed thick enough.
  • the invention is not limited to this case, but the width of the machinery room 6 may be greater than that of the shaft 2 if an even greater available space in the machinery room 6 is required.
  • the mechanism for moving up and down the elevator apparatus and the shape, structure and other features of the hoisting machine 12, the structural beams 20 and other items are not necessarily limited to what were described with reference to this mode for carrying out the invention, but other shape, structure and so forth can be usedwithin the scope of the invention.
  • the supporting parts are the parts supporting the machinery room floor, and the structural beams 20 constitute the supporting parts in this mode for carrying out the invention for instance.
  • the machinery base installation part is what is formed thicker than the rest of the machinery bases to bear the installation of the hoisting machine, and the machinery room middle part 32 constitutes this part in this mode for carrying out the invention for instance.
  • the machinery base supporting parts are what are supported by the aforementioned supporting parts, and the machinery room ends 30 constitute these parts in this mode for carrying out the invention for instance.
  • the parts of the machinery bases where the hoisting machine is to be installed are formed thicker than elsewhere, and these parts are fitted into the machinery room floor plate. Accordingly, the available space in the machinery room can be expanded by thinning the overall thickness of the machinery room floor while maintaining the necessary strength of the parts of the machinery bases where the hoistingmachine and other items are to be installed. Therefore, space saving in the machinery room can be achieved. Work can be done efficiently even in a small machinery room, thereby making possible improved elevator servicing.
  • the overall height of the machinery room can be prevented from being increased by the arrangement of a taller control device. Therefore, space saving in the machinery room can be achieved. Also, as part of the control device is so structured as to be fitted in, even a thinner control device can be stably installed.
