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.

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 ahandrail 610 provided on top of aconventional elevator cage 600, andFigure 21A is a front view, andFigure 21B is a side view seen from the right side ofFigure 21A . - As shown in
Figure 21 , theelevator 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 placedperpendicularly 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 upperlateral frame 22 of theright handrail 630, as shown inFigures 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.
- According to a non-claimed embodiment, 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.

- First, Embodiment 1 will be described with reference to
Figures 1 to 3 . -
Figure 1 , is a perspective view of ahandrail 110 installed on top of anelevator cage 100 according to Embodiment 1. - As shown in
Figure 1 , theelevator 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 thehandrail 110 is assembled on top of theelevator cage 100, andFigure 2A is a top view,Figure 2B is a front view, andFigure 2C is a side view seen from the right side ofFigure 2A . - As shown in
Figure 2 , thehandrails 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 thehandrail 110 is accommodated, andFigure 3A is a top view,Figure 3B is a front view, andFigure 3C is a side view seen from the right side ofFigure 3A . - As shown in
Figure 3 , in the state where thehandrail 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 toFigure 4 . -
Figure 4 illustrates, in section, a process of accommodating theleft handrail 120, andFigures 4A, 4C and 4E show sections parallel to the front, andFigures 4B, 4D and 4F show sections parallel to the side. - As shown in
Figures 4A, 4B , in the state where thehandrail 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 inFigures 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 lowervertical 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, the
handrails - In Embodiment 1, the lower
vertical 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 lower
vertical 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. - Next,
Embodiment 2 of the invention will be described with reference toFigures 5 to 7 . -
Figure 5 illustrates ahandrail 210 installed on top of anelevator cage 200 according toEmbodiment 2 andFigure 5A is a front view, andFigure 5B is a side view seen from the right side ofFigure 5A . - As shown in
Figure 5 , in a state where thehandrail 210 is installed, thehandrail 210 includes aleft handrail 220, aright handrail 230, and aback handrail 240, like thehandrail 110 in Embodiment 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 . A mountingscrew 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 18 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 mounting
screw 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 statewhere thehandrail 210 is accommodated, andFigure 6A is a front view, andFigure 6B is a side view seen from the right side ofFigure 6A . - As shown in
Figure 6 , the uppervertical 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 theleft handrail 220, andFigures 7A, 7C and 7E are front views, andFigures 7B, 7D and 7F are side views seen from the left side ofFigures 7A, 7C and 7E . InFigures 7 , inside parts of thesupport frame 4 and the mountingbrackets - Now, a process of accommodating the
left handrail 220 will be described with reference toFigure 7 . - As shown in
Figures 7A and 7B , theleft 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 uppervertical 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 inFigures 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 thehandrail 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 lowerportion of thelowervertical 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 inFigure 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 inFigure 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

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 inFigure 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 inFigure 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 1 and 2, and descriptions thereof will be omitted. - In this invention, a relationship between lengths of the upper and lower vertical 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 6 0 are not limited to those described inEmbodiment 3. - In

right handrails vertical frame 18 of theleft handrail 420 is first rotated and folded inward around the mountingscrew 74 in the arrow ① direction inFigure 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 the arrow ②direction inFigure 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 the arrow 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,
