Fig. 11 is a partially sectional view showing the car rescue device for the elevator at the time when therescue ladder 10 ofFig. 6 is removed from thecentral lighting cover 7 and extended.Fig. 12 is a perspective view showing the car rescue device for the elevator shown inFig. 11 . Referring toFigs. 11 and12 , therescue ladder 10 can be extended, when removed from thecentral lighting cover 7 located at the open position, downward from a retracted state. Therescue ladder 10 is extended to such a position that passengers within thecar chamber 1 can easily climb thereon. - Next, a procedure in rescuing the passengers within the
car chamber 1 from therescue hatch 6 will be described. First of all, therelease tool 34 such as the steel measure is inserted into the gap Q between theceiling frame 5 and thecentral lighting cover 7 to release the engagement of thecentral lighting cover 7 by the holdingdevice 16. Thus, thecentral lighting cover 7 is turned from the facing position to the open position due to the weight thereof. At this moment, therescue ladder 10 is also turned downward together with thecentral lighting cover 7. - After that, the rope as the
joint body 22 is undone to remove therescue ladder 10 from theremoval mounting device 11. After that, therescue ladder 10 is extended downward to ensure that the passengers within thecar chamber 1 can climb thereon. After that, thecanopy 35 is turned from within thecar chamber 1 to open therescue hatch 6. - In the car rescue device for the elevator constructed as described above, when the
central lighting cover 7 is turned from the facing position to the open position located below, therescue ladder 10 is turned together with thecentral lighting cover 7, so the structure for lowering therescue ladder 10 from therescue hatch 6 into thecar chamber 1 can be prevented from becoming complicated. The structure for lowering therescue ladder 10 into thecar chamber 1 simply through an operation from within thecar chamber 1 can be realized, so the amount of labor during the operation of rescuing the passengers can be reduced. In addition, the load imposed at the time when the passengers climb on therescue ladder 10 is not applied to thecentral lighting cover 7, so there is no need to reinforce thecentral lighting cover 7. Accordingly, a deterioration of the design within thecar chamber 1 can also be prevented. - The
rescue ladder 10 is retractable. Therefore, therescue ladder 10 can be made compact in an unused state, and can be extended in a used state to such a position that the passengers within thecar chamber 1 can easily climb thereon. - The
central lighting cover 7 for passing light from thelighting fixtures 9 into thecar chamber 1 is turnable, so the brightness within thecar chamber 1 can be prevented from dimming. -
Fig. 13 is a sectional view showing a car rescue device of an elevator according toEmbodiment 2 of the present invention.Fig. 14 is a sectional view showing a state in which therescue ladder 10 ofFig. 13 is removed from theceiling wall 4. Referring toFigs. 13 and14 , a pair ofgroove portions 40 facing each other are provided horizontally in each of the coupling portions between the ceiling wallcentral panel 12 and each of the ceilingwall lateral panels 13. One end of theladder turning shaft 18 is slidably inserted in one of thegroove portions 40, and the other end of theladder turning shaft 18 is slidably inserted in theother groove portion 40. That is, theladder turning shaft 18 is provided between thegroove portions 40 and can slide along thegroove portions 40. Therescue ladder 10 is removably provided on theladder turning shaft 18.Embodiment 2 of the present invention is identical toEmbodiment 1 of the present invention in other constructional details. - In the car rescue device for the elevator constructed as described above, the
ladder turning shaft 18 is horizontally movable with respect to thecar chamber 1, so the position of therescue ladder 10 can be adjusted in accordance with the position of therescue hatch 6 in rescuing passengers. Accordingly, even in the case where therescue hatch 6 is out of position due to, for example, restrictions such as the arrangement of components (e.g., an air-conditioner and a control panel for a door driving device) installed on thecar chamber 1, the operation of rescuing the passengers can be performed efficiently by adjusting the position of therescue ladder 10. - The
rescue ladder 10 can be removed from theladder turning shaft 18. Therefore, therescue ladder 10 can be taken out from therescue hatch 6 onto thecar chamber 1 and then used as a ladder for moving out of the hoistway after the passengers have escaped from therescue hatch 6 onto thecar chamber 1. Accordingly, there is no need to prepare means for moving from on thecar chamber 1 on a building side. As a result, flexible measures can be taken in an emergency. - In each of the foregoing embodiments of the present invention, the
rescue ladder 10 has a retractable structure. However, therescue ladder 10 may have a foldable structure. Further, instead of extending therescue ladder 10, the length of therescue ladder 10 may be fixed as long as therescue ladder 10 can be lowered to a position at which the passengers within thecar chamber 1 can climb thereon.
