Embodiment Construction
[0056] Hereinafter, one embodiment of the elevator apparatus according to the present invention will be described with reference to the drawings.
[0057] figure 1 It is a schematic sectional view for explaining the whole outline of the elevator which concerns on one Example of this invention. like figure 1 As shown, the elevator device 100 of this embodiment has: an elevator car 102 and a counterweight 103 that move up and down in the elevator passage 101 arranged in the building; a sling 104 that suspends the elevator car 102 and the counterweight 103; A hoist that is a driving device that moves the elevator car 102 and the counterweight 103 up and down; a sheave 106 attached to the hoist; and a pulley 107 around which the rope 104 is wound.
[0058] In this embodiment, the sheave 106 and the pulley 107 of the winch are arranged in the machinery room 105 located at the upper part of the lifting passage 101 . One end of the sling 104 connecting the elevator car 102 and the...

The invention aims at providing an elevator lift cage and an elevator device capable of detecting the clamped rope-like foreign matters regardless of the size thereof. In the elevator lift cage and the elevator device of the invention, the lift cage is arranged upon the lift cage frame, with a rubber vibration insulator arranged between the lift cage and the lift cage frame. The front end of the single-opened lift cage door is provided with a pressure-sensitive sensor, with the pressure-sensitive sensor being configured to be opposite to the front column of the lift cage when the lift cage door is in the closing state. A scooping-up board is arranged at the front end of the lower part of the lift cage door and the lower part of the front column of the lift cage. In the elevator lift cage and elevator device, the front column of the lift cage is provided with a tilting part. When observed inside the lift cage, the position of the tilting part located upon the front part of the lift cage is closer to the interior than the position of the surface revealed in the lift cage chamber when the lift cage is closed. The overlapped amount of the lift cage door and the front column of the lift cage in the closing / opening direction of the elevator door is smaller than the size of the gap between the lift cage door and the front column of the lift cage.
Description
technical field [0001] The invention relates to an elevator car and an elevator device in a single-door mode, which have a detection mechanism for detecting whether foreign objects such as ropes are caught by the elevator doors. Background technique [0002] As a prior art, for example, Patent Document 1 discloses a door device for an elevator in which a device for detecting rope-shaped foreign objects is provided at the front end in the closing direction of the door of the elevator car at the entrance and exit of the elevator car. Pressure-sensitive sensor (for example, refer to Patent Document 1). [0003] In addition, for example, a solution is disclosed in Patent Document 2, in which in order to detect a rope-shaped foreign object dropped on the car floor, a scooping plate that guides the rope-shaped foreign object to the pressure-sensitive sensor is provided (for example, refer to Patent Document 2 ). [0004] Patent Document 1: Japanese Patent Laid-Open No. 2009-2696...
