Specifically, the maintenance worker first raises the left handrail 14 placed in the top portion of the car so as to turn it around the lower pin 20. Then, after making the left handrail 14 in an upright state, the maintenance worker lowers the left handrail 14 slowly and erects it on the car upper frame 6 so that the upper pin 21 provided in the lower end portion of the vertical pillar 17 is arranged in the stopper groove 22b of the connecting portion 16. Also, the maintenance worker erects the right handrail 13 on the car upper frame 6 by the same procedure as described above.
  • the maintenance worker loosens the wing bolt of the locking device 28, thereby making the rear handrail 15 in a turnable state, and turns the rear handrail 15 around the turning devices 26 and moves it to the right handrail 13 side.
  • the vertical pillar 23 on the right side of the rear handrail 15 is fixed to the vertical pillar 17 on the rear side of the right handrail 13.
  • Embodiment 1 of the present invention when the right handrail 13 or the left handrail 14 is assembled, merely by engaging the upper pin 21 provided in the lower end portion of the vertical pillar 17 with the stopper groove 22b of the mounting fixture 22, an effect of preventing the handrail device 12 from overturning can be achieved, so that the conventional stoppers, latch mechanisms, and the like which are provided only for preventing the overturn of the assembled handrail device 12, are unnecessary. Therefore, work that is performed by the maintenance worker in a stooping posture to prevent the overturn of the handrail device 12 is not needed, which improves the work efficiency, and thereby the assembling time and storing time can be shortened. Also, since the conventional stoppers, latch mechanisms, and the like need not be provided, the construction can be simplified, and hence the handrail device 12 can be provided at a low cost.
  • the handrail device 12 is stored by being placed on the car upper frame 6 provided at a position separating upward a predetermined distance from the top surface of the cab 1, there is no fear that elevator equipment installed on the top surface of the cab 1 is damaged, and also a phenomenon that the vibrations of a fan etc. installed on the top surface of the cab 1 transmit to the handrail device 12 to generate noise can be prevented.
  • the rear handrail 15 of the stored handrail device 12 is arranged within the thickness of the left handrail 14, the total thickness of the handrail device 12 placed on the car upper frame 6 can be kept to only the sum of the thickness of the right handrail 13 and the thickness of the left handrail 14. It is a matter of course that even if the rear handrail 15 cannot be arranged within the thickness of the left handrail 14, the same effect as described above can be achieved if the rear handrail 15 can be arranged within the thicknesses of the right handrail 13 and the left handrail 14 in the stored state of the handrail device 12.
