Japanese Utility Model Publication No. 5-12467 JP 2005-132547 A

  In the conventional elevator apparatus shown in Patent Document 1, since the handrail device is fixed to the upper beam, the support structure of the handrail device has a cantilever structure that is weak against moment force. For this reason, as the size of the handrail device in the depth direction of the car increases, it is necessary to secure a greater strength against the moment force in the fixing portion to the upper beam, and the weight of the handrail device itself increases. Deterioration of transportability and installability associated with the problem becomes a problem.

  On the other hand, in the conventional elevator apparatus shown in Patent Document 2, since the handrail device is directly fixed to the canopy, the weight of the handrail device and the total load applied to the handrail device are borne by the canopy, and the strength of the canopy is It was necessary to raise.

  Here, when the handrail device is fixed to the upper beam, it is basically a cantilever structure. The reason for this is that the car floor of the elevator for passengers, the elevator for human cargo (mainly human) and the elevator for the bed is prevented. It is mentioned that it is a bed structure. The anti-vibration floor structure is a structure in which the car floor is supported by an anti-vibration device (such as rubber or a spring). In the anti-vibration floor structure, when a load is applied to the car floor, the car floor sinks into the car frame due to the deflection of the vibration isolator. At this time, the car room fixed to the car floor is also displaced downward.

  For this reason, in the conventional handrail device fixed to the upper beam, a support point cannot be added to the canopy that is displaced in the vertical direction with respect to the upper beam, and a cantilever structure is formed.

  The present invention has been made to solve the above-described problems, and firmly supports the car handrail device on the car with a simple configuration while preventing the weight of the car handrail device and the canopy from being increased. It is an object to obtain an elevator apparatus that can be used.

  An elevator apparatus according to the present invention includes a car frame, a car having a car room that is displaceable in the vertical direction with respect to the car frame, and a car upper handrail device provided at an upper portion of the car. Has a vertical handrail that is connected to the canopy that constitutes the ceiling of the cab and is vertically set on the canopy, and a horizontal handrail that is connected to the car frame and the vertical handrail and is disposed horizontally. At least one of a connection part of the vertical handrail to the canopy, a connection part of the horizontal handrail to the car frame, a connection part of the horizontal handrail to the vertical handrail, an intermediate part of the vertical handrail, and an intermediate part of the horizontal handrail The elastic support part which absorbs the displacement to the up-down direction of the cage | basket | cab with respect to the cage | basket | car frame by elastic deformation is interposed.

  In the elevator apparatus of the present invention, the car upper handrail device is connected to the car frame and the canopy, and the vertical displacement of the car room is absorbed by the elastic deformation of the elastic support portion. While preventing the weight of the canopy, the car handrail device can be firmly supported on the car with a simple configuration.
