Thus, the work table 40 can be locked to the support panel 43 to maintain the standing state, and the lock is released by loosening the wing nut 54 and rotating the screw rod 53 upward. Be able to.

  The support panel 43 is provided with a detection switch 57 as a means for preventing the operation table 40 from being forgotten. This detection switch 57 has a switch element that is turned on / off in response to the raising / lowering operation of the work table 40, and holds, for example, the operating circuit of the observation elevator 1 in an open state when the work table 40 has not returned to a predetermined standing state. It is like that.

  In addition, 46 shown in FIG. 3 is the illuminating device for car room illumination attached under the ceiling of the cab 2.

  Next, the operation will be described.

  Normally, the work table 40 is held in a predetermined standing state, and the observation elevator 1 is operated in this state, and passengers in the cab 2 can view the outside through the transparent members 8 of the observation unit 6. At this time, if the work table 40 is overlaid on the ceiling transparent part of the observing part 6, it looks unsightly and the view of the sight is obstructed. Therefore, the work table 40 does not obstruct or obstruct the view and can be viewed well.

  On the other hand, at the time of work such as maintenance of the observation elevator 1, the operation of the observation elevator 1 is stopped, and an operator enters the hoistway 10 and gets on the ceiling of the cab 2. Then, the stopper 51 is removed, the wing nut 54 is loosened, the screw rod 53 is rotated upward, and the lock of the work table 40 with respect to the support panel 43 is released.

  Next, the hoist 47 is operated to turn the work table 40 in an upright state around the support shaft 39 to the back side of the cab 2 to bring it into a substantially horizontal lying state. At this time, since the damper 39 is provided on the support shaft 39, the work table 40 rotates gently, and safely falls.

  Thereafter, the stopper 35 a is removed from the fixed handrail 27, and the movable handrail 30 is pulled out from the inside of the fixed handrail 27 toward the back side of the cab 2 to a predetermined length. Then, the movable handrail 30 pulled out to a predetermined length is locked to the fixed handrail 27 by a stopper 35b and fixed at that position. Next, the auxiliary beam 33 overlapping the horizontal beam 32 at the tip of the movable handrail 30 is moved downward along the guide bar 34, and the horizontal beam 32 and the auxiliary beam 33 are supported so as to be aligned in parallel in the vertical direction.

  Thereafter, an operator gets on the work table 40 and performs maintenance work of the observation elevator 1, cleaning work of the inner surface of the enclosure wall 12 of the hoistway 10, and the like. The work area on the ceiling of the cab 2 has been expanded by the development of the work table 40, so that the worker can proceed efficiently while moving freely to a required position on the ceiling of the cab 2.

  Since the work table 40 is supported by the chain 48, it can sufficiently receive the load from the worker, and the work area on the ceiling of the cab 2 is surrounded by the fixed handrail 27 and the movable handrail 30. For this reason, there is no danger of an operator falling from the ceiling, and the work can be proceeded safely.

  On the other hand, the entire area of the transparent ceiling of the observation section 6 in the cab 2 is covered with the work table 40, so that the worker does not get directly on the transparent ceiling, and the transparent ceiling is not transparent. There is no risk of scratching or damaging the ceiling.

  After the work such as maintenance is completed, the auxiliary beam 33 at the tip of the movable handrail 30 is lifted upward along the guide bar 34 and overlapped with the horizontal beam 32, and the stopper 35b is loosened to move the movable handrail 30. The movable handrail 30 is inserted and stored inside the fixed handrail 27 along the guide pipe 29, and the stored movable handrail 30 is locked and fixed to the fixed handrail 27 by a stopper 35a.

  Next, the hoist 47 is operated, the work table 40 is pulled upward via the chain 48, and is stood up so as to close to the support panel 43. Then, both ends of the upper end of the work table 40 are locked to the fixed handrail 27 by the stopper 51, the screw rod 53 is further rotated downward, the wing nut 54 is tightened, and the intermediate portion in the width direction of the work table 40 is secured. The support panel 43 is locked and fixed.

  Thereafter, the operation of the observation elevator 1 is resumed. At this time, the work table 40 is in an upright state separating from the transparent ceiling portion of the observation unit 6, and therefore the work table 40 can be viewed well without obstructing the field of view.

  By the way, when the work table 40 falls from the standing state, the detection switch 57 is turned off by the operation, and the operation circuit of the observation elevator 1 is opened. Then, when the work table 40 is properly returned to the upright state after the work such as maintenance is completed, the detection switch 57 is turned on, and the observation elevator 1 can be operated.

  Therefore, when the operation of lifting the work table 40 is forgotten after the work is completed or when the standing state is incomplete, the detection switch 57 is not turned on but is kept off, and the operation of the observation elevator 1 is performed. For this reason, forgetting to raise the work table 40 or noticing the incomplete standing state, it is possible to prevent inadvertent leaving.

  As described above, according to the work table apparatus of the present embodiment, the work area on the ceiling of the cab 2 can be expanded efficiently by operating the hoist 47 during the maintenance work or the like to incline the work table 40. The work can be performed safely, and the work table 40 is lifted and raised after the work is completed, so that the transparent ceiling part of the view part 6 can be opened and a good view can be realized. Then, it can be managed without the troublesome work of attaching / detaching the work table 40 to / from the cab 2 and the troublesome consideration of securing the space for storing the work table 40.
