Abstract
Description
- 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 aconventional 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. - As shown in Figure 21, the
elevator cage 600 includes acage 2 and ahandrail 610. - The
handrail 610 includes aleft handrail 620, aright handrail 630, and aback handrail 640. Thehandrails support frame 4. Thesupport frame 4 is fastened to thecage 2 via afastening column 6. On top of thefastening column 6, arope passage 8 is provided that passes a rope for hoisting or lowering theelevator cage 600 through a pulley (not shown) placed under thecage 2. - The
left handrail 620 and theback handrail 640 each includes twovertical frames 14 placed perpendicularly to a ceiling surface of thecage 2, and between the twovertical frames 14, includes a lowerlateral frame 20 and an upperlateral frame 22 placed perpendicularly to thevertical frames 14. Theright handrail 630 includes two vertical frames, each of which is a combination of a lowervertical frame 16 and an uppervertical frame 18, and between the two vertical frames, includes a lowerlateral frame 20 and an upperlateral frame 22 placed perpendicularly to thevertical frames - In order to save a space on top of the
elevator cage 600, thehandrail 610 can be rotated and folded 90° inward around amounting screw 34 that penetrates amounting member 32 and thevertical frame 14 or the lowervertical frame 16, to be accommodated. The vertical frame of theright handrail 630 is adapted so that when thehandrail 610 is folded, the uppervertical frame 18 is placed under the lowervertical frame 16. - The
handrail 610 has a safety device that detects accommodation of the handrail. The safety device includes asafety switch 92 provided on theright handrail 630, and apressing bracket 96 mounted to theleft handrail 620 via astring 94. When thehandrail 610 is accommodated, thepressing bracket 96 turns on thesafety switch 92 to allow the accommodation of the handrail to be detected. - When the
handrail 610 having such a configuration for an elevator is folded, theleft handrail 620 can be placed over the uppervertical frame 18 and the lowerlateral frame 22 of theright handrail 630, as shown in Figures 21C and 21D. This can prevent the left andright handrails right handrails right handrails handrail 610 to save a space, and allows a relatively high handrail to be placed even in a small space. - When the elevator is operated, the space on top of the
elevator cage 600 containing thehandrail 610 and the device on top of acage 12 is preferably minimized. On the other hand, inspections or other operations performed on top of the cage require a relatively high handrail in terms of safety. - However, if a high handrail having the above described structure is to be provided on top of a narrow elevator cage, for example, a folding position of the vertical frame, that is, a position of the
mounting screw 34 has to be relatively high so as to prevent the handrail from hitting the device on top of acage 12 when the handrail is folded. Thus, a relatively high space is required even if the handrail is folded and accommodated. - When safety inspections or other operations are performed on top of the elevator cage, an operator rides on the cage from an elevator hall of a top floor of a building where the elevator is provided. In this case, a handrail requires to be assembled from the hall before the operator rides on the elevator cage for safety during the operation. However, it is difficult to assemble the handrail from the hall. This increases time for installing the handrail, and thus increases overall operation time during the operation, causing the elevator to stop for long hours and imposing inconvenience on users of the elevator.
- Further, when performing the operation, the operator cannot ride on the cage without releasing a safety device. After the operation, in order to operate the elevator, the safety device requires to be operated to detect accommodation of the handrail. A switch of the safety device requires to be turned on from the hall after the accommodation of the handrail, which is difficult depending on the position of the safety switch. Even if an elevator has halls in two directions, a direction of riding on the cage or a direction of stepping off the cage is limited depending on the position of the safety switch. This may increase time for the operation, causing the elevator to stop for long hours.
- The invention has objects to solve the above described problems, provide a high handrail that can be accommodated even in a small space, and reduce time for installing and accommodating the handrail and for operating a safety device, and proposes an improved handrail on an elevator cage.
- In the present invention, a handrail on top of an elevator cage comprises a handrail provided on top of an elevator cage, a support frame that supports the handrail, and a fastening column that fastens the support frame to the cage. The handrail includes side handrails provided on top of the cage in parallel with two opposite sides of the cage, and a back handrail provided on top of the cage perpendicularly to the side handrails, at least the side handrails of the handrails include adjustment means for adjusting a height, and the handrail includes accommodation means for allowing the handrail to be horizontally folded and accommodated on a top surface of the cage.
- Accordingly, a relatively high handrail can be provided on top of the elevator cage, and accommodated even in a small space
- In the present invention, a handrail on top of an elevator cage comprises a handrail provided on top of a cage of an elevator, a support frame that supports the handrail, and a fastening column that fastens the support frame to the cage. The handrail includes two side handrails provided in parallel with two sides of the elevator, and a back handrail provided perpendicularly to the side handrails. The side handrails has automatic accommodation means that makes it possible that one of the side handrails is accommodated to allow the other of the side handrails to be accommodated.
- Accordingly, time for installing and accommodating the handrail can be reduced, and thus overall operation time can be reduced.
- In present invention, a handrail on top of an elevator cage comprises a safety device that confirms a state of accommodation and/or installation on top of the elevator cage. An automatic accommodation means operates or stops the safety device at the same time as the handrail is accommodated or installed.
- Accordingly, time for operating or stopping the safety device can be reduced and the overall operation time can be reduced.

- Now, embodiments of the invention will be described with reference to the drawings. In the drawings, the same reference numerals denote same or corresponding parts, and descriptions thereof will be simplified or omitted.
- First,
Embodiment 1 of the invention will be described with reference to Figures 1 to 3. - Figure 1 is a perspective view of a
handrail 110 installed on top of anelevator cage 100 according toEmbodiment 1 of the invention. - As shown in Figure 1, the
elevator cage 100 includes acage 2 and ahandrail 110. Thehandrail 110 includes aleft handrail 120, aright handrail 130, and aback handrail 140. Thehandrails support frame 4. Thesupport frame 4 is fastened to thecage 2 by afastening column 6. On top of thefastening column 6, arope passage 8 is provided. Therope passage 8 is used to pass a hoisting and lowering wire rope through a pulley (not shown) under thecage 2 to hoist and lower theelevator cage 100. On top of thecage 2, a device on top of acage 12 is provided. - Figure 2 schematically shows a state where the
handrail 110 is assembled on top of theelevator cage 100, and Figure 2A is a top view, Figure 2B is a front view, and Figure 2C is a side view seen from the right side of Figure 2A. - As shown in Figure 2, the
handrails vertical frame 16 and an uppervertical frame 18, and between the two vertical frames, includes a lowerlateral frame 20 and an upperlateral frame 22 placed perpendicularly to thevertical frames - The lower
vertical frame 16 is a hollow square prism. The lowervertical frame 16 has throughholes vertical frame 18 is a square prism. The uppervertical frame 18 has an installation throughhole 28 and an accommodation throughhole 30 in lower and upper portions thereof, respectively. - A mounting
bracket 32 is an L-shaped metal fitting with two surfaces crossing substantially perpendicularly to each other, and one surface thereof is fastened to thesupport frame 4. A mountingscrew 34 penetrates the other surface of the mountingbracket 32 and the throughhole 24 provided in the lowervertical frame 16, and thus the lowervertical frame 16 connects to thesupport frame 4. - In a state where the
handrail 110 is installed, a mountingscrew 36 penetrates the throughhole 26 of the lowervertical frame 16 and the installation throughhole 28 of the uppervertical frame 18, and thus the uppervertical frame 18 is fastened to the lowervertical frame 16. - The lower
lateral frame 20 is fastened perpendicularly to the lowervertical frame 16 between upper ends of the two lowervertical frames 16. The upperlateral frame 22 is fastened perpendicularly to the uppervertical frame 18 between top ends of the two upper vertical frames 18. - Figure 3 shows a state where the
handrail 110 is accommodated, and Figure 3A is a top view, Figure 3B is a front view, and Figure 3C is a side view seen from the right side of Figure 3A. - As shown in Figure 3, in the state where the
handrail 110 is accommodated, the uppervertical frame 18 is accommodated in the lowervertical frame 16. In a state where the uppervertical frame 18 is accommodated, thehandrails screw 34. Theback handrail 140 is placed under the left andright handrails - Next, a state of accommodating the
handrail 110 will be described with reference to Figure 4. - Figure 4 illustrates, in section, a process of accommodating the
left handrail 120, and Figures 4A, 4C and 4E show sections parallel to the front, and Figures 4B, 4D and 4F show sections parallel to the side. - As shown in Figures 4A, 4B, in the state where the
handrail 110 is installed, the lowervertical frame 16 is mounted to thesupport frame 4 by the mountingbracket 32, and fastened perpendicularly to a top surface of thecage 2. The mountingscrew 36 is passed through the throughhole 26 of the lowervertical frame 16 and the installation throughhole 28 of the upper vertical frame, thus the uppervertical frame 18 is fastened to the lowervertical frame 16 such that theleft handrail 120 is placed in a highest position. - When the
left handrail 120 is accommodated from this state, the mountingscrew 36 that fastens the uppervertical frame 18 to the lowervertical frame 16 is first pulled out. This causes the uppervertical frame 18 to be removed from the lowervertical frame 16. In this state, as shown in Figures 4C and 4D, the uppervertical frame 18 is pulled down and slid into the lowervertical frame 16 to be accommodated. Then, the mountingscrew 36 is passed through the accommodation throughhole 30 of the uppervertical frame 18 and the throughhole 26 of the lower vertical frame to be fastened. - Then, as shown in Figures 4E and 4F, the lower
vertical frame 16 that has accommodated the uppervertical frame 18 is rotated and folded approximately 90° inward around the mountingscrew 34. In this state, theleft handrail 120 is accommodated. - The
right handrail 130 and theback handrail 140 are similarly accommodated. - Thus, the
handrail 110 is folded in two steps. This prevents interference when the left and right handrails are folded, and allows the handrail to be accommodated in a small space without the device on top of acage 12 or the like being an obstacle. - As described above, the
left handrail 120, theright handrail 130, and theback handrail 140 are provided on top of thecage 2, but not limited to the three sides, the handrails may be provided on all four sides, or on the left and right sides only. - In
Embodiment 1, thehandrails - In
Embodiment 1, the lowervertical frame 16 is the hollow square prism, and the uppervertical frame 18 can be slid into the lowervertical frame 16 to be accommodated. However, not limited to this, for example, conversely, the uppervertical frame 18 may be a hollow square prism, and the lowervertical frame 16 may be accommodated in the uppervertical frame 18. - The shapes or the positions of the vertical frames, the lateral frames, and the mounting brackets are not limited to those described in
Embodiment 1 within the scope of the invention. - In
Embodiment 1, the lowervertical frame 16 corresponds to a lower handrail of the invention, and the uppervertical frame 18 corresponds to an upper handrail of the invention. Portions including the throughhole 26 of the lowervertical frame 16, the installation throughhole 28, the accommodation throughhole 30, and the mountingscrew 36 correspond to adjustment means and mounting means of the invention. Portions including the throughhole 24 of the lower vertical frame, the mountingbracket 32, and the mountingscrew 34 correspond to accommodation means of the invention. - Next,
Embodiment 2 of the invention will be described with reference to Figures 5 to 7. - Figure 5 illustrates a
handrail 210 installed on top of anelevator cage 200 according toEmbodiment 2 of the invention, and Figure 5A is a front view, and Figure 5B is a side view seen from the right side of Figure 5A. - As shown in Figure 5, in a state where the
handrail 210 is installed, thehandrail 210 includes aleft handrail 220, aright handrail 230, and aback handrail 240, like thehandrail 110 inEmbodiment 1. - The
left handrail 220 and theright handrail 230 each includes two vertical frames, each of which is a combination of a lowervertical frame 16 and an uppervertical frame 18, and between the two vertical frames, includes a lowerlateral frame 20 and upperlateral frame 22 placed perpendicularly to the vertical frames, thus include four frame rods. - In
Embodiment 2, the lowervertical frame 16 has throughholes vertical frame 18 has a throughhole 42 in a lower portion thereof. A mountingbracket 44 is placed on a connecting portion between the lowervertical frame 16 and the uppervertical frame 18. The mountingbracket 44 has two through holes in upper and lower portions thereof. Amountingscrew 46 penetrates the lower through hole of the mountingbracket 44 and the throughhole 40 of the lower vertical frame. A mountingscrew 48 penetrates the upper through hole of the mountingbracket 44 and the throughhole 42 of the uppervertical frame 18. Thus, the lowervertical frame 16 and the uppervertical frame 18 are connected via the mountingbracket 44. The mountingbracket 44 is rotatable around the mountingscrew 46. The uppervertical frame 16 is rotatable around the mountingscrew 48. - On the other hand, the
back handrail 240 includes a lowerlateral frame 20 and an upperlateral frame 22, but vertical frames are not formed in two steps unlike the left andright handrails vertical frames 14 each constituted by one column are placed on both ends of the upper and lower lateral frames 20, 22 perpendicularly thereto. - Like
Embodiment 1, a mountingscrew 34 is passed through the throughhole 24 provided in a lower portion of the lowervertical frame 16 or thevertical frame 14, and a mountingbracket 32, thus thehandrails support frame 4. - Figure 6 schematically illustrates a state where the
handrail 210 is accommodated, and Figure 6A is a front view, and Figure 6B is a side view seen from the right side of Figure 6A. - As shown in Figure 6, the upper
vertical frame 18 of each of theleft handrail 220 and theright handrail 230 is rotated and folded 180° inward at the mountingbracket 44 provided between the lowervertical frame 16 and the uppervertical frame 18. In this state, the lowervertical frame 16 is rotated and folded 90° inward at the mountingbracket 32 that mounts the lowervertical frame 16 and asupport frame 4. That is, the left andright handrails - On the other hand, the
back handrail 240 is folded 90° inward at the mountingbracket 32 that mounts thesupport frame 4 and thevertical frame 14. At this time, theback handrail 240 is placed under the left andright handrails - Figure 7 schematically illustrates, partially in perspective, a state of accommodating the
left handrail 220, and Figures 7A, 7C and 7E are front views, and Figures 7B, 7D and 7F are side views seen from the left side of Figures 7A, 7C and 7E. In Figure 7, inside parts of thesupport frame 4 and the mountingbrackets - Now, a process of accommodating the
left handrail 220 will be described with reference to Figure 7. - As shown in Figures 7A and 7B, the
left handrail 220 is installed on top of acage 2. - In this state, the lower
vertical frame 16 is mounted to thesupport frame 4 via the mountingbracket 32, and fastened perpendicularly to a top surface of thecage 2. The uppervertical frame 18 is connected, via the mountingbracket 44, to the top of the lowervertical frame 16, in a superposed manner in the same direction. - Figures 7C and 7D show a state where the upper
vertical frame 18 is folded 180° inward at a portion between the lowervertical frame 16 and the uppervertical frame 18. - In this state, the mounting
bracket 44 rotates 90° inward around the mountingscrew 46 that penetrates the thorough hole of the mountingbracket 44 and the throughhole 40 of the lowervertical frame 16. The uppervertical frame 18 rotates 90° around the mountingscrew 48 that penetrates the throughhole 42 to be folded inward. Thus, as shown in Figures 7C, 7D, the uppervertical frame 18 is folded 180° inward and placed in parallel with the lowervertical frame 16. - Figures 7E, 7F show a state where the
handrail 210 is folded. - Here, with the upper
vertical frame 18 being folded 180° inward, the lower vertical frame is rotated and folded 90° inward around the mountingscrew 34 at a lower portion of the lowervertical frame 16. Thus, both the lowervertical frame 16 and the uppervertical frame 18 are horizontally folded on top thecage 2. - The accommodation process of the
left handrail 220 has been described, but theright handrail 230 is similarly accommodated. For theback handrail 240, thevertical frame 14 is constituted by one column, and, as shown in Figure 6, simply rotated and folded 90° inward around the mountingscrew 34 to be accommodated. This allows thehandrail 210 to be accommodated in the state shown in Figure 6. - Here, no front handrail is provided opposite the
back handrail 240, thus unlike the left andright handrails back handrail 240 is not folded in two steps. A device on top of acage 12 that tends to be an obstacle when the handrail is folded is placed near the front, thus the device on top of acage 12 does not become an obstacle when theback handrail 240 is folded. Thus, theback handrail 240 is folded in a single step. - This prevents the left and
right handrails handrail 210 is accommodated, and prevents the device on top of acage 12 from becoming an obstacle. Thus, a high handrail can be provided even on top of a narrow elevator while saving a space. - In
Embodiment 2, the mountingbracket 44 through which the mounting screws 46, 48 are passed is used as rotation means to fold the uppervertical frame 18 inward, but not limited to this, anything that can once fold the uppervertical frame 18 may be used. - The shapes or the positions of the mounting
bracket 44 and the mounting screws 46, 48 are not limited to those described inEmbodiment 2 within the scope of the invention. - Other configurations are the same as those in
Embodiment 1, and descriptions thereof will be omitted. - In
Embodiment 2, portions including the throughholes bracket 44, and the mounting screws 46, 48 correspond to adjustment means and connection means of the invention. - Next,
Embodiment 3 of the invention will be described with reference to Figures 8 to 13. - Figure 8 schematically show a state where a
handrail 310 is installed on top of anelevator cage 300 according toEmbodiment 3 of the invention, and Figure 8A is a front view, and Figure 8B is a side view seen from the right side of Figure 8A. - As shown in Figure 8, the
handrail 310 includes aleft handrail 320, arighthandrail 330, and aback handrail 340, andthehandrails 320, 330, 340 are mounted to asupport frame 4 likeEmbodiment 1. - The
left handrail 320 and theright handrail 330 each includes two vertical frames, each of which is a combination of a lowervertical frame 16 and an uppervertical frame 18, and between the two vertical frames, includes a lowerlateral frame 20 and an upperlateral frame 22 placed perpendicularly to the vertical frames. The lowerlateral frame 20 is placed near middle portions of the two lowervertical frames 16. The upperlateral frame 22 is placed on upper portions of the two upper vertical frames 18. - On the other hand, a vertical frame of the
back handrail 240 is constituted by onevertical frame 14. Theback handrail 240 includes twovertical frames 14, and between thevertical frames 14, includes a lowerlateral frame 20, and an upperlateral frame 22 placed perpendicularly to the vertical frames 14. - Figure 9 schematically shows the vertical frames of the left and
right handrails vertical frame 16, and Figure 9B schematically shows the uppervertical frame 18. In Figures 9A and 9B, the left shows a front, and the right shows a side. - The lower
vertical frame 16 is a hollow square prism having an open surface on one side. As shown in Figure 9A, a verticalU-shaped groove 52 is provided in a top of the lowervertical frame 16. The verticalU-shaped groove 52 is formed by vertically hollowing the top of the lowervertical frame 16 into a U-shape. Below the verticalU-shaped groove 52, alower engagement pole 54 is provided that extends perpendicularly to a vertical direction of the lowervertical frame 16. In the front view on the left side of Figure 9A, thelower engagement pole 54 extends forward and backward perpendicularly to the drawing sheet, and in the side view on the right side, thelower engagement pole 54 extends toward the left and the right perpendicularly to the lowervertical frame 16. Below thelower engagement pole 54, a lateralU-shaped groove 56 is provided. The lateralU-shaped groove 56 is formed by hollowing a side of the lowervertical frame 16 into a U-shape perpendicularly to the vertical direction of the lowervertical frame 16. A side where the lateralU-shaped groove 56 is provided, that is, a left side in the front view on the left side of Figure 9A is an open surface. LikeEmbodiments hole 24 is provided in a lower portion of the lowervertical frame 18. - As shown in Figure 9B, an
elliptical hole 58 is provided in a lower portion of the uppervertical frame 18. In the front view on the left side of Figure 9B, theelliptical hole 58 is a hole passing through the uppervertical frame 18 in an elliptical shape perpendicularly to the drawing sheet. Anupper engagement pole 60 is provided above theelliptical hole 58. Theupper engagement pole 60 extends in the same direction as thelower engagement pole 54 of the lowervertical frame 16, specifically, in the front view on the left side of Figure 9B, theupper engagement pole 60 extends forward and backward perpendicularly to the drawing sheet, and in the side view on the right side, theupper engagement pole 60 extends toward the left and the right perpendicularly to the uppervertical frame 14. - Figures 10 to 12 schematically illustrate, in section, a process of accommodating the
left handrail 320, and Figures 10A, 11A and 12A show front views, and Figures 10B, 11B and 12B show side views. Figure 13 schematically shows a state where thehandrail 310 is accommodated, and Figure 13A is a front view, and Figure 13B is a side view seen from the right side of Figure '13A. - As shown in Figure 10, the lower
vertical frame 16 is mounted to asupport frame 4 by passing a mountingscrew 34 through a mountingbracket 32 and a through hole. - The
upper engagement pole 60 of the uppervertical frame 18 is engaged into the verticalU-shaped groove 52 of the lowervertical frame 16, and thelower engagement pole 54 of the lowervertical frame 16 is inserted into an upper portion of theelliptical hole 58 of the uppervertical frame 18. In this manner, the lowervertical frame 16 and the uppervertical frame 18 are connected to form a vertical frame in a line. The lowerlateral frame 20 and the upperlateral frame 22 provided between the two vertical frames are substantially parallel to a top surface of acage 2. - From this state, pulling up the upper
vertical frame 18 as shown in Figure 11 allows the uppervertical frame 18 to rotate. In this state, theupper engagement pole 60 engaged into the verticalU-shaped groove 52 is displaced upward and removed from the verticalU-shaped groove 52. Pulling up the upper vertical frame causes thelower engagement pole 54 to be displaced downward in theelliptical hole 58. - In this state, the upper
vertical frame 18 can be moved toward the left and the right, and in order to fold thehandrail 310, the uppervertical frame 18 is rotated and tilted approximately 180° outward around thelower engagement pole 54 as shown in Figure 12. In this state, part of the uppervertical frame 18 is accommodated in the lowervertical frame 16 from the open surface thereof. However, the upper portion of the uppervertical frame 18 and the upperlateral frame 22 hit thesupport frame 4, which prevents the uppervertical frame 18 from rotating completely 180°, and causes the uppervertical frame 18 to stop in a state of being accommodated partway in the lowervertical frame 18. - For the
right handrail 330, in an accommodated state similarly to theleft handrail 320, the lowervertical frame 16 is folded 90° inward around the mountingscrew 34 to be accommodated as shown in Figure 13. At this time, the upper portion of the uppervertical frame 18 and the upperlateral frame 22, which have hit thesupport frame 4 and have not been completely accommodated, are completely accommodated. - Other configurations are the same as those in
Embodiments - In this invention, a relationship between lengths of the upper and lower support frames is not limited to that described in
Embodiment 3. However, the configuration inEmbodiment 3 allows the handrail to be longer, thus allowing a high handrail that can be accommodated in a small space to be installed. - In the invention, the shapes or the positions of the vertical
U-shaped groove 52, thelower engagement pole 54, the lateralU-shaped groove 56, theelliptical hole 58, and theupper engagement pole 60 are not limited to those described inEmbodiment 3. - In
Embodiment 3, portions including the verticalU-shaped groove 52, thelower engagement pole 54, the lateralU-shaped groove 56, theelliptical hole 58, and theupper engagement pole 60 correspond to adjustment means and connection means of the invention. - Next,
Embodiment 4 of the invention will be described with reference to Figures 14 to 16. - Figure 14 schematically show a state where a
handrail 410 is installed on top of anelevator cage 400 according toEmbodiment 4 of the invention, and Figure 14A is a front view, and Figure 14B is a side view seen from the right side of Figure 14A. - As shown in Figure 14, the
handrail 410 includes aleft handrail 420, aright handrail 430, and aback handrail 440. - The
left handrail 420 and theright handrail 430 each includes two vertical frames, each of which is a combination of a lowervertical frame 16 and an uppervertical frame 18 via a mountingbracket 70, and between the two vertical frames, includes a lowerlateral frame 20 and an upperlateral frame 22 placed perpendicularly to the vertical frames. - An
accommodation rod 72 is provided on the mounting bracket provided between the lowervertical frame 16 and the uppervertical frame 18 of the left andright handrails accommodation rod 72 is, as described later, rotatably mounted, at one end thereof, to an upper left portion of the mountingbracket 70 of theleft handrail 420 such that a placement angle between theaccommodation rod 72 and the mountingbracket 70 can be changed, and at the other end thereof, to a lower left portion of the mountingbracket 70 of theright handrail 430 such that the placement angle between theaccommodation rod 72 and the mountingbracket 70 can be changed. - Figure 15 schematically shows a state where the
handrail 410 is accommodated, and Figure 15A is a front view, and Figure 15B is a side view seen from the right side of Figure 15A. - As shown in Figure 15, the left and
right handrails handrail 410 are folded 90° inward at the mountingbracket 70 to be accommodated. Theback handrail 440 is rotated and folded 90° inward around a mountingscrew 34 to be accommodated under the left andright handrails - When the
handrail 410 is folded from an installed state in Figure 14 to an accommodated state in Figure 15, theright handrail 430 is automatically folded by folding theleft handrail 420. - Figures 16A to 16C are front views, partially in perspective, illustrating a state of folding the left and
right handrails handrail 410. In Figures 16A to 16C, the mountingbracket 70 is shown in perspective. - As shown in Figure 16A, the mounting
bracket 70 is rotatably mounted, at a lower right portion thereof, to the lowervertical frame 16 and the uppervertical frame 18 on the front side of theleft handrail 420 by a mountingscrew 74. Another mountingbracket 70 is rotatably mounted, at an upper right portion thereof , to the lowervertical frame 16 and the uppervertical frame 18 on the front side of theright handrail 420 by a mountingscrew 74. - The upper
vertical frame 18 is adhered to the mountingbracket 70. Theaccommodation rod 72 is rotatably mounted, at one end thereof, to the upper left portion of the mountingbracket 70 of theleft handrail 420 by amountingscrew 76. Theaccommodation rod 72 is rotatably mounted, at the other end thereof, to the lower left portion of the mountingbracket 70 of theright handrail 430 by a mountingscrew 76. - When the left and
right handrails vertical frame 18 of theleft handrail 420 is first rotated and folded inward around the mountingscrew 74 in thearrow 1 ○ direction in Figure 16A. - At this time, as the upper
vertical frame 18 of theleft handrail 420 moves, the mountingbracket 70 fastened to the uppervertical frame 18 rotates around the mountingscrew 74 in thearrow 2 ○ direction in Figure 16B. As the mountingbracket 70 of theleft handrail 420 rotates, the mountingscrew 76 that mounts theaccommodation rod 72 rotates, with the placement angle between theaccommodation rod 72 and the mountingbracket 70 being appropriately changed, to push theaccommodation rod 72 in thearrow 3 ○ direction. This causes the mountingscrew 76 that mounts theaccommodation rod 72 to the mountingbracket 70 provided on theright handrail 430 to be pushed in thearrow 4 ○ direction, and rotated around the mountingscrew 74. At this time, the mountingbracket 70 of theright handrail 430 rotates in thearrow 4 ○ direction together with the mountingscrew 76. During the rotation, the placement angle between theaccommodation rod 72 and the mountingbracket 70 is appropriately changed. The uppervertical frame 18 fastened to the mountingbracket 70 of theright handrail 430 rotates together with the mountingbracket 70, and tilted in thearrow 5 ○ direction. - The case where the
left handrail 420 is folded to automatically accommodate theright handrail 430 has been described, but, conversely, theright handrail 430 may be folded in thearrow 5 ○ direction to automatically fold theleft handrail 420. In this case, contrary to the case of first folding theleft handrail 420, theright handrail 430 is tilted in thearrow 5 ○ direction to rotate the mountingbracket 70 in thearrow 4 ○ direction, and theaccommodation rod 72 is pulled in thearrow 3 ○ direction. This causes the mountingbracket 70 to rotate in thearrow 2 ○ direction to fold theleft handrail 420 in thearrow 1 ○ direction. - If a force in the
arrow 3 ○ direction is applied to theaccommodation rod 72 without folding the left orright handrails arrow 2 ○ direction is applied to the mountingbracket 70 of theleft handrail 420, and a force in thearrow 4 ○ direction is applied to the mountingbracket 70 of theright handrail 430. This allows the left andright handrails arrows 1 ○ and 5 ○, respectively, to be automatically accommodated. - The case of accommodating the handrails has been described, but the handrails can be installed by applying a force in the direction opposite the above described direction to the
left handrail 420, theright handrail 430, or theaccommodation rod 72. - Other configurations are the same as those in
Embodiments 1 to 3, and descriptions thereof will be omitted. - Configuring as described above allows both the left and
right handrails accommodation rod 72, when the left andright handrails - In
Embodiment 4, portions including the mountingbracket 70, theaccommodation rod 72, and the mounting screws 72, 74 correspond to automatic accommodation means of the invention. - Next,

handrails vertical frames 14, and between the twovertical frames 14, includes a lowerlateral frame 20 and an upperlateral frame 22 placed perpendicularly to the vertical frames 14. Eachvertical frame 14 is mounted to asupport frame 4 so as to be folded inward, by passing a mountingscrew 34 through a throughhole 24 and a mountingbracket 32 provided in a lower portion. On thevertical frames 14 on the front sides of the left andright handrails accommodation rods brackets 32 such that placement angles between theaccommodation rods vertical frames 14 can be changed. - The other ends of the
accommodation rods accommodation rotation plate 84 such that placement angles between theaccommodation rods accommodation rotation plate 84 can be changed. Theaccommodation rotation plate 84 is mounted to an accommodationrotation axis plate 86, and is rotatable around acentral axis 88. Inside the accommodationrotation axis plate 86, aswitch 90 of a safety device is provided on a position that abuts against theaccommodation rotation plate 84 when theaccommodation 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. - As shown in Figure 18, in the state where the

right handrails - During accommodation, in Figure 19, as shown by the
arrow 1 ○, theleft handrail 620 is folded inward, then theaccommodation rod 80 rotates at mounting screws at both ends thereof, and moves in thearrow 2 ○ direction, with the placement angle with respect to thevertical frame 14 or theaccommodation rotation plate 84 being appropriately changed. This causes theaccommodation rotation plate 84 to be pushed in thearrow 3 ○ direction, to rotate around thecentral axis 88, and then, to pull theaccommodation rod 82 in thearrow 4 ○ direction. Thus, thevertical frame 14 of theright handrail 530 provided on the other end of theaccommodation rod 82 is tilted in thearrow 5 ○ direction. In this manner, for thehandrail 510, theleft handrail 520 is accommodated to accommodate theright handrail 530 at the same time. - Figure 20 schematically shows a state of turning on the
switch 90 of the safety device when theaccommodation rotation plate 84 enters an accommodation state, and Figure 20A shows an OFF state of theswitch 90 of the safety device, and Figure 20B shows an ON state of theswitch 90. - As shown in Figure 20A, in a state where the
handrail 510 is installed, theaccommodation rotation plate 84 is placed above the accommodationrotation axis plate 86, and thus theswitch 90 of the safety device is OFF. On the other hand, in a state where thehandrail 510 is accommodated, as shown in Figure 20B, theaccommodation rotation plate 84 is placed on theswitch 90 of the safety device. Thus, theswitch 90 is always ON in the state where thehandrail 510 is accommodated. - The case where the
left handrail 520 is folded to fold theright handrail 530 has been described, but theright handrail 530 may be folded to fold theleft handrail 520. In this case, contrary to the case of first folding theleft handrail 52, in Figure 19, a force in thearrow 5 ○ direction is applied to theright handrail 530, a force in thearrow 4 ○ direction is applied to theaccommodation rod 82, a force in thearrow 3 ○ direction is applied to theaccommodation rotation plate 84, a force in thearrow 2 ○ direction is applied to theaccommodation rod 80, and then theleft handrail 520 is folded in thearrow 1 ○ direction. Alternatively, the left andright handrails 520 can be accommodated at the same time by applying the force in thearrow 2 ○ or 4 ○ direction to theaccommodation rod accommodation rotation plate 84 in thearrow 3 ○ direction allows the forces in the directions of thearrows 2 ○, 1 ○, and thearrows 4 ○, 5 ○ to be applied, and thus allows the left and right handrails to be accommodated at the same time. Theswitch 90 of the safety device can be automatically turned on by any of the accommodation methods. - The case where the left and
right handrails right handrails right handrails accommodation rods accommodation rotation plate 84. In this case, theswitch 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 accommodation rotation plate 84, the accommodationrotation axis plate 86, thecentral axis 88, and theswitch 90 of the safety device are not limited to those described inEmbodiment 5 within the scope of the invention. - Other configurations are the same as those in
Embodiments 1 to 4, and descriptions thereof will be omitted. - 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.
- In
Embodiment 5, portions including theaccommodation rods accommodation rotation plate 84, the accommodationrotation axis plate 86, and thecentral axis 88 correspond to adjustment means of the invention. - As described above, 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. Thus, 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.
