Description

  The present invention relates to an elevator apparatus, and more particularly, to a means for preventing the engagement of various cords with a guide rail fixing member provided in a hoistway.

  In general, an elevator device is a lifting body such as a car or counterweight that moves up and down in the hoistway, a guide rail that guides the hoisting body, and a building frame that is assembled in the hoistway wall or hoistway. A rail clip that is fixed directly or via a rail bracket, and an end portion that is connected to the elevating body, and an intermediate portion that includes a main rope that is wound around the hoisting machine. In addition, a loop-shaped governor rope that is driven by raising and lowering the car is stretched over the entire length of the hoistway as a safety device. This governor rope is wound around a pulley of a speed governor installed at the top of the hoistway, and a tension wheel is suspended at the bottom of the hoistway. In addition, in the elevator apparatus, a tail cord that transmits power and signals from the fixed side of the hoistway to the car is connected to the car, and a balance chain (cable) that connects the car and the counterweight at the bottom. / Rope).

  The above-mentioned various cords, that is, main ropes, governor ropes, tail cords, and balancing chains (cables / ropes) are arranged using a narrow space in the hoistway. Swings as the building shakes. In particular, in recent years, the length of the cord-like body has increased with the height of the building, and the cord-like body has become easier to swing with the flexibility of the building. There is a high risk of engaging with guide rail fixing members such as installed rail brackets and rail clips.

  In order to prevent the occurrence of such inconvenience, the applicant of the present application previously has a cord that prevents the cord-like body from approaching the bolt head in the vicinity of the bolt head that connects the rail clip to the rail bracket. An elevator apparatus provided with a member approach preventing means has been proposed (see, for example, the abstract of Patent Document 1). According to the invention described in Patent Document 1, since the cord-like body does not engage with the head portion of the bolt constituting the guide rail fixing member, a reliable elevator device can be obtained.
