Definitions
- the present invention relates to a handrail on top of an elevator cage, and more specifically, to a handrail provided on top of an elevator cage during an operation on top of the cage.
- Figure 21 schematically shows a handrail 610 provided on top of a conventional elevator cage 600, and Figure 21A is a front view, and Figure 21B is a side view seen from the right side of Figure 21A .
- the elevator cage 600 includes a cage 2 and a handrail 610.
- the handrail 610 includes a left handrail 620, a right handrail 630, and a back handrail 640.
- the handrails 620, 630, 640 are mounted to a support frame 4.
- the support frame 4 is fastened to the cage 2 via a fastening column 6.

- the mounting screw 76 that mounts the accommodation rod 72 rotates, with the placement angle between the accommodation rod 72 and the mounting bracket 70 being appropriately changed, to push the accommodation rod 72 in the arrow 3 direction.
- the mounting bracket 70 of the right handrail 430 rotates in the arrow 4 direction together with the mounting screw 76.
- the placement angle between the accommodation rod 72 and the mounting bracket 70 is appropriately changed.
- the upper vertical frame 18 fastened to the mounting bracket 70 of the right handrail 430 rotates together with the mounting bracket 70, and tilted in the arrow 5 direction.
- the right handrail 430 may be folded in the arrow 5 direction to automatically fold the left handrail 420.
- the right handrail 430 is tilted in the arrow 5 direction to rotate the mounting bracket 70 in the arrow 4 direction, and the accommodation rod 72 is pulled in the arrow 3 direction. This causes the mounting bracket 70 to rotate in the arrow 2 direction to fold the left handrail 420 in the arrow 1 direction.
- a force in the arrow 3 direction is applied to the accommodation rod 72 without folding the left or right handrails 420, 430
- a force in the arrow 2 direction is applied to the mounting bracket 70 of the left handrail 420
- a force in the arrow 4 direction is applied to the mounting bracket 70 of the right handrail 430.
- This allows the left and right handrails 420, 430 to be folded in the directions of the arrows 1 and 5, respectively, to be automatically accommodated.
- the handrails can be installed by applying a force in the direction opposite the above described direction to the left handrail 420, the right handrail 430, or the accommodation rod 72.
- Configuring as described above allows both the left and right handrails 420, 430 to be accommodated or installed at a time simply by applying a force to one of the handrails or the accommodation rod 72, when the left and right handrails 420, 430 are accommodated or installed. This allows the handrail to be accommodated or installed easily and quickly even on top of a narrow elevator, and reduces time for accommodating the handrail.
- portions including the mounting bracket 70, the accommodation rod 72, and the mounting screws 72, 74 correspond to automatic accommodation means of the invention.
- Embodiment 5 of the invention will be described with reference to Figures 17 to 20 .
- Figure 17 schematically shows a state where a handrail 510 is installed on top of an elevator cage 500 according to Embodiment 5 of the invention
- Figure 17A is a front view
- Figure 17B is a side view seen from the right side of Figure 17A .
- the handrail 510 provided on top of the elevator cage 500 according to Embodiment 5 includes, like Embodiment 4, left and right handrails 520, 530 and a back handrail 540, and has a function of folding the left and right handrails 520, 530 at a time, but the configurations thereof are different.
- a switch of a safety device can be automatically turned on or off when the left and right handrails 520, 530 are accommodated or installed.
- the handrails 520, 530, 540 each includes two vertical frames 14, and between the two vertical frames 14, includes a lower lateral frame 20 and an upper lateral frame 22 placed perpendicularly to the vertical frames 14.
- Each vertical frame 14 is mounted to a support frame 4 so as to be folded inward, by passing a mounting screw 34 through a through hole 24 and a mounting bracket 32 provided in a lower portion.
- accommodation rods 80, 82 are rotatably mounted above the mounting brackets 32 such that placement angles between the accommodation rods 80, 82 and the vertical frames 14 can be changed.
- the other ends of the accommodation rods 80, 82 are rotatably mounted to an accommodation rotation plate 84 such that placement angles between the accommodation rods 80, 82 and the accommodation rotation plate 84 can be changed.
- the accommodation rotation plate 84 is mounted to an accommodation rotation axis plate 86, and is rotatable around a central axis 88. Inside the accommodation rotation axis plate 86, a switch 90 of a safety device is provided on a position that abuts against the accommodation rotation plate 84 when the accommodation rotation plate 84 rotates.
- Figure 18 schematically shows a state where the handrail 510 is accommodated, and Figure 18A is a front view, and Figure 18B is a side view seen from the right side of Figure 18B .
- the vertical frame 14 is folded 90° inward to be accommodated.
- the left and right handrails 520, 530 are folded on the back handrail 540 folded.
- Figure 19 shows a state where the left and right handrails 520, 530 are being accommodated.
- the left handrail 620 is folded inward, then the accommodation rod 80 rotates at mounting screws at both ends thereof, and moves in the arrow 2 direction, with the placement angle with respect to the vertical frame 14 or the accommodation rotation plate 84 being appropriately changed.
- the vertical frame 14 of the right handrail 530 provided on the other end of the accommodation rod 82 is tilted in the arrow 5 direction. In this manner, for the handrail 510, the left handrail 520 is accommodated to accommodate the right handrail 530 at the same time.
- Figure 20 schematically shows a state of turning on the switch 90 of the safety device when the accommodation rotation plate 84 enters an accommodation state
- Figure 20A shows an OFF state of the switch 90 of the safety device
- Figure 20B shows an ON state of the switch 90.
- the accommodation rotation plate 84 is placed above the accommodation rotation axis plate 86, and thus the switch 90 of the safety device is OFF.
- the accommodation rotation plate 84 is placed on the switch 90 of the safety device.
- the switch 90 is always ON in the state where the handrail 510 is accommodated.
- the left and right handrails 520,530 can be accommodated at the same time by applying the force in the arrow or 4 direction to the accommodation rod 80 or 82.
- Rotating the accommodation rotation plate 84 in the arrow 3 direction allows the forces in the directions of the arrows 2, 1, and the arrows 4, 5 to be applied, and thus allows the left and right handrails to be accommodated at the same time.
- the switch 90 of the safety device can be automatically turned on by any of the accommodation methods.
- the left and right handrails 520, 530 can be installed at a time by applying a force in the direction opposite the above described direction to any of the left and right handrails 520, 530, the accommodation rods 80, 82, and the accommodation rotation plate 84.
- the switch 90 of the safety switch can be automatically turned off to automatically release the safety device by any of the installation methods.
- the shapes or the positions of the accommodation rods 80, 82, the accommodation rotation plate 84, the accommodation rotation axis plate 86, the central axis 88, and the switch 90 of the safety device are not limited to those described in Embodiment 5 within the scope of the invention.
- Configuring as described above allows the left and right handrails to be folded at a time with a simple function. Further, the safety device can be automatically operated or released at the same time as the handrail is accommodated or installed. This reduces time for installing the handrail or other operations.
- portions including the accommodation rods 80, 82, the accommodation rotation plate 84, the accommodation rotation axis plate 86, and the central axis 88 correspond to adjustment means of the invention.
- the aspect of the invention including the adjustment means for adjusting the height of the handrail allows the handrail to be folded and accommodated with the heights of the side handrails being low.
- a relatively high handrail can be provided on top of the elevator cage, and accommodated even in a small space, while preventing interference between the side handrails during accommodation, or interference with the device on top of a cage.
- the aspect of the invention including the automatic accommodation means makes it possible that one of the side handrails is accommodated or installed to allow the other of the side handrails to be accommodated or installed. This reduces time for installing and accommodating the handrail during inspection or other operations of the elevator, and thus reduces overall operation time.
- the aspect of the invention that allows the safety device to be automatically operated or stopped reduces time for operating or stopping the safety device. This also reduces the overall operation time during the inspection or other operations of the elevator.
