Reference numeral 9 denotes an upper guide device which is provided at both upper ends of the elevator car 7 and which guides the elevator car 7 to move up and down. 10 is a lower guide device which is provided at both lower ends. Reference numeral 11 denotes an elevator emergency stop mechanism which is arranged between the bottom of the elevator car 7 and the lower guide device 10 and is located right above the lower guide device 10.

The upper guide device 9 is an elevator car 7
Is provided with an L-shaped plate-shaped frame 9a standing upright at the upper end of the frame, and a roller 9b pivotally supported by the vertical surface of the frame 9a and rolling along the inner surface of the guide rail 6 on the bent portion side. . Further, the lower guide device 10 is rotatably supported by an L-shaped plate-shaped frame 10a that hangs down at the lower end of the elevator car 7 and the lower center of the vertical surface of the frame 10a, and extends along the outer surface of the guide rail 6 on the bent portion side. And a roller 10b that rolls. Reference numeral 12 is a guide roller arranged in the upper guide device 9 and the lower guide device 10.

The emergency stop mechanism 11 includes a guide rail 6
And a guide fitting 11b that guides the brake element 11a to surely contact the guide rail 6 when the brake element 11a moves upward.

The conventional elevator is constructed as described above, and the elevator car 7 moves up and down in the hoistway 1 along the guide rail 6 through the upper guide device 9 and the lower guide device 10. At this time, the rollers 9b of the upper guide device 9 and the rollers 10b of the lower guide device 10 are not connected to the elevator car 7
It moves up and down smoothly and acts to prevent it from falling in the depth direction. In addition, the guide rollers 12 of the upper guide device 9 and the lower guide device 10 roll on the inner surface of the guide rail 6 on the non-folding side to smoothly move the elevator car 7 up and down, and also to the left and right to fall and swing. Acts to prevent.

In addition, it took a lot of time for maintenance and inspection.

In Japanese Utility Model Publication No. 53-39005, in a gradual emergency stop mechanism used in a high-speed elevator for gradually braking by utilizing a spring force, an emergency stop mechanism itself is provided with an inspection window for braking. A technique is disclosed in which the gap between the child and the guide rail can be viewed directly from the front,
There is no particular description of a roll type early-fire emergency stop mechanism used in a low-speed elevator. In addition, the emergency stop mechanism itself
Since the inspection window is provided on the emergency stop mechanism itself
Mechanical strength may decrease.

Therefore, according to the present invention, even in a narrow hoistway, the gap between the guide rail and the brake element of the lower guide device can be directly and directly inspected from the front direction, so that the inspection can be performed easily, safely and surely, and the maintenance inspection is low. An object of the present invention is to provide an elevator guide device that can be manufactured at low cost and does not reduce mechanical strength .
