Definitions

  • the present invention relates: to an elevator apparatus to carry a passenger or a package; and in particular to an elevator apparatus having an opening and closing door for platform installed at an elevator platform.
  • An opening and closing door for platform (hereunder described merely as an opening and closing door) through which a passenger comes in and out is installed at a gateway of an elevator apparatus at an elevator platform.
  • the opening and closing door is configured by: installing two doors so as to overlap; and closing a gateway by shifting one door until it touches an end surface of the gateway on the closing side and shifting the other door up to a halfway position when the opening and closing door is closed. Then when the opening and closing door is opened, the gateway is fully opened by: shifting the one door and the other door up to the end surface of the gateway on the opening side; and overlapping the one door and the other door to each other in the state.
  • Such an opening and closing door is called an opening and closing door of a two-leaved single-swing type.
  • opening and closing doors are configured so as to fully close in order to prevent flames and hot air from intruding into a hoistway when a fire breaks out in a building but flames and hot air may sometimes intrude into a hoistway through gaps between a building and opening and closing doors. Then the intruding flames and hot air may sometimes reach hanger rails and hanger rollers installed in order to suspend opening and closing doors and shift the opening and closing doors smoothly.
  • the hanger rails extend in the directions in which the opening and closing doors shift and are fixed to the upper part of the hoistway above the platform gateway in the building with bolts or the like. Then the hanger rollers installed in door hangers fixed to the opening and closing doors roll over rails formed at the upper parts of the hanger rails and shift the opening and closing doors smoothly. Then a buffer material comprising a synthetic resin such as an urethane resin or a nylon resin is installed over the rolling surfaces of the hanger rollers and the configuration is arranged so as to: alleviate impact between the hanger rollers and the rail surfaces of the hanger rails; and inhibit shifting sounds and vibrations accompanying the shift of the opening and closing doors.
  • a buffer material comprising a synthetic resin such as an urethane resin or a nylon resin
  • the buffer material may sometimes melt by flames or hot air, however, because it comprises a synthetic resin and the melting buffer material drops directly into a hoistway. On this occasion, if a passenger cage is located on the lower side, the melting buffer material may drop onto the passenger cage and get fire undesirably. Otherwise, even when a passenger cage does not exist, a fire may break out in a hoistway sometimes. For the reason, a measure of inhibiting a melting buffer material from dropping into a hoistway is desired.
  • Japanese Patent Application Laid-Open No. 2002-220181 proposes to install a gutter-shaped member to receive a melting buffer material and drain the melting buffer material toward the platform side under a hanger rail so that the melting buffer material may not drop into a hoistway.
  • an opening and closing door having a hanger rail to suspend the opening and closing door, a pocket to fix the hanger rail, a door hanger to be fixed to the upper part of the opening and closing door and suspend the opening and closing door to the hanger rail, a hanger roller to be rotatably installed in the door hanger and roll over the hanger rail, and a buffer material installed over the rolling surface of the hanger roller, in order to prevent the melting buffer material of the hanger roller from dropping onto the side of a hoistway, a gutter-shaped member to receive and drain the melting buffer material toward the center of the opening and closing door is installed under the hanger roller.
  • PTL 2 describes an elevator layer door, specially an elevator fireproof heat insulation layer door.
  • An opening and closing door proposed in PTL 1 is configured so that a melting buffer material of a hanger roller may be received by a gutter-shaped member, accumulated in the center of the opening and closing door, and drained toward the side of a platform and hence the melting buffer material may sometimes drop over a gateway upper frame constituting a platform gateway in a building. Since the gateway upper frame is located above the platform gateway, the temperature tends to rise by flames and hot air and sometimes rises to a high temperature exceeding the ignition point of a buffer material.
  • An object of the present invention is to provide an elevator apparatus having a novel opening and closing door excellent in fire-resistance performance.
  • a feature of the present invention is to inhibit a melting buffer material from dropping over a gateway upper frame of a high temperature by: arranging a buffer material receiving member that extends in the directions of shifting a hanger roller and receives the melting buffer material between the upper part of the gateway upper frame and the hanger roller; and receiving the melting buffer material with the buffer material receiving member.
  • the present invention makes it possible to: receive a melting buffer material with a buffer material receiving member; and inhibit the melting buffer material from dropping over a gateway upper frame of a high temperature. As a result, the danger of igniting a melting buffer material in a hoistway reduces and an opening and closing door excellent in fire-resistance performance can be provided.
  • Fig. 1 is a view of the upper part of a two-leaved single-swing opening and closing door according to a first embodiment of the present invention viewed from a side
  • Fig. 2 is a view of the opening and closing door shown in Fig. 1 viewed from a hoistway side
  • Fig. 3 is a sectional view taken on line A-A in Fig. 2
  • Fig. 4 is a sectional view taken on line B-B in Fig. 2 .
  • a first opening and closing door 1a and a second opening and closing door 1b installed at a platform gateway shift to fully closed positions respectively and close the platform gateway in a closing state; and shift to fully open positions respectively and overlap each other in an opening state.
  • the first opening and closing door 1a and the second opening and closing door 1b are: opened toward the right side shown with the arrow O in Fig. 2 ; and closed toward the left side shown with the arrow C in Fig. 2 . Consequently, the second opening and closing door 1b is located on the closer side than the first opening and closing door 1a (on the platform side).
  • door hangers 2a and 2b are fixed to the top ends of the first opening and closing door 1a and the second opening and closing door 1b by a method of bolting or welding.
  • the door hangers 2a and 2b are suspended over hanger rails 4a and 4b extending in the directions of shifting the opening and closing doors 1a and 1b on the inner side of a hoistway 8.
  • the hanger rails 4a and 4b are fixed to a pocket 3 fixedly arranged on the side of the hoistway 8.
  • the hanger rails 4a and 4b have different distances from the wall surface of the hoistway 8 respectively in response to the positional relationship between the first opening and closing door 1a and the second opening and closing door 1b; and are located in conformity with hanger rollers that will be described later.
  • the pocket 3 is fixed to brackets 7a, 7b, and 7c with bolts 20 and the brackets 7a, 7b, and 7c are fixed to the inner wall surface of the hoistway 8 with bolts 21.
  • a door closing side vertical frame 11 and a door opening side vertical frame 12 and gateway upper frames 10a and 10b connecting them, those constituting a platform gateway, are installed at a platform H and the gateway upper frames 10a and 10b are connected at the lower part of the pocket 3 and fixed to the inner wall surface of the hoistway 8 with bolts 22.
  • the gateway upper frame 10a extends to the vicinity of the first opening and closing door 1a and likewise the gateway upper frame 10b extends to the vicinity of the second opening and closing door 1b.
  • the surfaces of the gateway upper frame 10a and the gateway upper frame 10b on the side of the platform are adjusted so as to have an identical plane (single plane) and look good. Further, the gateway upper frame 10a and the gateway upper frame 10b may also be formed integrally.
  • the first opening and closing door 1a is configured so as to: roll over the hanger rail 4a through two hanger rollers 5a and 5b arranged at the door hanger 2a; be inhibited from shifting upward by swing stopping rollers 6a and 6b; and avoid derailing. That is, the hanger rollers 5a and 5b are located between the door hanger 2a and the inner wall surface of the hoistway 8 and right above the hanger rail 4a. Further, the swing stopping rollers 6a and 6b are located between the door hanger 2a and the inner wall surface of the hoistway 8 and right below the hanger rail 4a. The configuration therefore is arranged so as to interpose the hanger rail 4a between the hanger rollers 5a and 5b and the swing stopping rollers 6a and 6b.
  • Such a configuration is similarly applied to the second opening and closing door 1b and the second opening and closing door 1b is configured so as to: roll over the hanger rail 4b through two hanger rollers 5c and 5d arranged at the door hanger 2b; be inhibited from shifting upward by swing stopping rollers 6c and 6d; and avoid derailing.
  • the hanger rollers 5c and 5d are located between the door hanger 2b and the inner wall surface of the hoistway 8 and right above the hanger rail 4b.
  • the swing stopping rollers 6c and 6d are located between the door hanger 2b and the inner wall surface of the hoistway 8 and right below the hanger rail 4b.
  • the configuration therefore is arranged so as to interpose the hanger rail 4b between the hanger rollers 5c and 5d and the swing stopping rollers 6c and 6d.
  • a buffer material 13 comprising a synthetic resin such as an urethane rubber is installed over the outer peripheries of the hanger rollers 5a, 5b, 5c, and 5d and the configuration is arranged so as to: alleviate impact between the hanger rollers 5a, 5b, 5c, and 5d and the rail surfaces of the hanger rails 4a and 4b; and inhibit shifting sounds and vibrations accompanying the shift of the first opening and closing door 1a and the second opening and closing door 1b.

  • the opening and closing doors 1a and 1b of such configurations when the platform H gets fire, the first opening and closing door 1a, the second opening and closing door 1b, the gateway upper frames 10, the door closing side vertical frame 11, and the door opening side vertical frame 12 are exposed to flames and hot air of the fire and moreover heat is transferred by radiation. Then at the upper parts of the first opening and closing door 1a and the second opening and closing door 1b, heated air: flows in as hot air through gaps between the gateway upper frames 10a and 10b and the first opening and closing door 1a and the second opening and closing door 1b; and raises the temperatures of the opening and closing mechanism members of the opening and closing doors 1a and 1b.
  • the constituent members and the opening and closing mechanism members of the opening and closing doors 1a and 1b are not ignited and do not burn by hot air because they mostly comprise metal materials such as steel plates but the buffer material 13 applied to the hanger rollers 5a, 5b, 5c, and 5d: comprises a synthetic resin; hence has a relatively low melting point; and has the feature of melting, being ignited, and burning.
  • the buffer material 13 melts and drops over the gateway upper frames 10.
  • the gateway upper frames 10a and 10b are arranged above a platform gateway, the possibility of being exposed to flames and high temperature air tends to increase and the temperatures of the gateway upper frames 10a and 10b tend to be higher than the temperatures of the other constituent members and opening and closing mechanism members of the opening and closing doors 1a and 1b.
  • the gateway upper frames 10 receive heat by fire from the platform H and the temperatures rise to temperatures exceeding the ignition point of the buffer material 13 therefore, there is the danger that the melting and dropping buffer material 13: touches the gateway upper frames 10a and 10b of high temperatures; ignites by itself; starts combustion; and induces fire in a hoistway.

  • the radiation inhibiting materials are fixed to the buffer material receiving members 14a, 14b-1, and 14b-2 and the gateway upper frames 10a and 10b in the present embodiment, it is possible to: install a radiation inhibiting material at least over the bottom surfaces of the buffer material receiving members 14a and 14b-1; and if necessary install a radiation inhibiting material over the bottom surface of the buffer material receiving member 14b-2 and the bottom inner surfaces of the gateway upper frames 10a and 10b.
  • a heat radiation inhibiting material 16b-2 has to be installed over the buffer material receiving member 14b-2.
  • a buffer material receiving member 14b-1 is installed in each of the opening and closing doors 1a and 1b individually. Also by such a structure, it is possible to receive a melting buffer material 13 by a buffer material receiving member 14b-1 and inhibit the melting buffer material 13 from dropping over gateway upper frames 10a and 10b of high temperatures and hence the danger of generating fire in a hoistway reduces and an opening and closing door excellent in fire-resistance performance is obtained.
  • the buffer material receiving member 14b-1 is not required to be separated unlike a buffer material receiving member 14a in the first to third embodiments and may be a buffer material receiving member 14b-1 of a continuous shape.
  • an opening and closing door of a two-leaved center-swing type it is advantageous to: omit a buffer material receiving member 14b-1; and form only a buffer material receiving member 14b-2 by bending the lowermost end of a pocket 3 toward the side of opening and closing doors 1a and 1b. It is possible thereby to form the buffer material receiving member 14b-2 integrally and continuously over the two opening and closing doors 1a and 1b.
  • the functions and effects of: being able to omit the buffer material receiving member 14b-1; facilitating operations during attaching; and being able to save material costs can be obtained.
  • a configuration of: arranging a buffer material receiving member extending in the directions of shifting a hanger roller between the upper part of a gateway upper frame of a platform gateway and the hanger roller; and receiving a melting buffer material by the buffer material receiving member is adopted. It is possible thereby to receive the melting buffer material by the buffer material receiving member and inhibit the melting buffer material from dropping over the gateway upper frame of a high temperature and hence the danger of generating fire in a hoistway reduces and the fire-resistance performance comes to be excellent.
  • the present invention is not limited to the embodiments stated above and includes various modified examples.
  • the above embodiments are explained in detail in order to make the present invention easy to understand and the present invention is not necessarily limited to the cases having all the configurations explained above.
