Description

  INDUSTRIAL APPLICABILITY In the hoistway having a viewing surface such as glazing, the present invention can secure a landscape outside from the inside of the rear falling weight or horizontal weight falling layout of a viewing elevator having a viewing window. The present invention relates to a balance weight device for an elevator for observation.

  Conventional viewing elevators have a viewing window mainly on the front wall (corresponding to the wall opposite to the surface on which the car door is provided), so the counterweight often has a side-down layout. However, as an adverse effect of the counterweight being arranged on the side of the car, there is a problem that the front wall width (frontage dimension) becomes small with respect to the same hoistway size. For this reason, a layout after the counterweight is required.

  However, when the layout after the counterweight is dropped, there is a problem that the counterweight and the counterweight peripheral device can be seen from the observation window on the front wall and obstruct the view. For this reason, a structure has been proposed in which a hoistway for raising and lowering the counterweight is arranged underground so that the counterweight cannot be seen (see, for example, Patent Document 1).
