(1-2. side frame portion uses blocking-up portion)
Explain in the side edge part of an opposite side with door shield portion side of blocking-up door-plate 116 and the formation in the gap between the side frame 108 under door-plate 116 closing state being used for reference to Fig. 3 to Fig. 8.Here; Under the situation of double door; Door-plate 116a and comprise position relation and the door-plate 116b between the door camera bellows portion of side frame 108a and the position that comprises between the camera bellows portion of side frame 108b concerns left-right symmetric; Constitute identically, therefore, only the formation that is used to block door-plate 116b and comprises the gap between the door camera bellows portion of side frame 108b is described.Be used for shown in Fig. 3 (a) to as along an example of the cutaway view of the B-B line of Fig. 1, be used to block door-plate 116b with a camera bellows portion that comprises side frame 108b between the diagram explained of the formation in gap.Under door-plate 116 closing state, at door-plate 116b and comprise between the door camera bellows portion of side frame 108b and have gap by reference symbol 302 expressions.In order to block this gap 302, assembling side frame portion uses breaking member 124b.Side frame portion is formed by stacking by the rubber-like polymer member at least a portion of rubber-like imcombustibility parts and the one side at least that is disposed at the imcombustibility parts with breaking member 124.
Door-plate 116b and the side edge part opposite side of door shield portion side are fixed in breaking member 124b through the base end part 124c by rubber-like imcombustibility component set-up in side frame portion.Side frame portion is closely fixing with the mode that does not form the gap between this breaking member 124b and the door-plate 116b with breaking member 124b.For example, metal pressing plate 304 is adhered to the base end part 124c of breaking member 124b, base end part 124c that is adhered and pressing plate 304 closely is fixedly linked on integratedly the side edge part of door-plate 116 through stop screw 306 through sticker.Side frame portion extends along the almost total length of the above-below direction of door-plate 116b with breaking member 124b continuously, for example, is situated between by stop screw 306, and the spacing by appointment closely is fixed in door-plate 116b through base end part 124c.
Side frame portion is integrally formed with a lateral margin side and the base end part 124c of breaking member 124b, becomes the extension 124d that extends to the configuration side of side frame 108b from base end part 124c.Extension 124d has the effect of spring by the rubber-like imcombustibility component set-up that begins to extend from base end part 124c, and said base end part 124c is by rubber-like imcombustibility component set-up.Be built up the part 124e that is made up of the rubber-like polymer member at extension 124d, this part 124e is disposed at least a portion as a relative side with side frame 108b of the part of this extension 124d.Shown in Fig. 3 (a); Side frame portion is with the extension 124d maintenance of breaking member 124b and the posture of the surperficial relative tilt of side frame 108b; Simultaneously; For example crooked to curve circular-arc mode backward, the side of polymer member part 124e that under the door closing state, is disposed at the pars intermedia of extension 124d flexibly and closely contacts with the bight of side frame 108b.Through this contact, the gap 302 between door-plate 116b and the side frame 108b is by blocking-up airtightly.
Near the fire propagation stop, side frame portion becomes high temperature with breaking member 124b, and polymer member part 124e also maybe be because of former thereby disappearances such as fusings.Even such state of affairs takes place, because extension 124d is by rubber-like imcombustibility component set-up, so shown in Fig. 3 (b), the side of the pars intermedia of extension 124d flexibly and closely contacts with the bight of side frame 108b.Through this contact, even under the situation that polymer member part 124e disappears, the gap 302 between door-plate 116b and the side frame 108b is also by blocking-up airtightly.
As previously mentioned, use breaking member 124a with the identical side frame portion of breaking member 124b formation, can block door-plate 116a and comprise the gap between the camera bellows portion of side frame 108a through being provided with side frame portion as shown in Figure 3.
Embodiment according to above explanation; Under door-plate 116 closing state; Even when high temperature, also can block side edge part and each gap between the side frame 108 of an opposite side with door shield portion of door-plate 116, can limit cigarette and flame and flow into hoistway side through this gap from the stop side.
In addition, through sticker pressing plate 304 is assemblied in the base end part 124c of side frame portion with breaking member 124 in advance, under this state, base end part 124c is fixed in the side edge part of door-plate 116 through stop screw 306.Therefore, through strengthening base end part 124c with pressing plate 304, the distortion of base end part 124c is prevented, and in the side edge part of door-plate 116, side frame portion is with being blocked between breaking member 124 and the door-plate 116 with breaking member 124 close fit in side frame portion.
Moreover; In embodiment as shown in Figure 3, side frame portion is with the extension 124d maintenance of breaking member 124 and the posture of the surperficial relative tilt of side frame 108, simultaneously; Crooked to curve circular-arc mode backward; The side of polymer member part 124e that is disposed at the pars intermedia of extension 124d flexibly and closely contacts with the bight of side frame 108, and thus, the gap 302 between door-plate 116 and the side frame 108 is by blocking-up airtightly.But the gap 302 of blocking airtightly between door-plate 116 and the side frame 108 through breaking member is not limited to aforementioned manner.For example; Side frame portion is with the extension 124d maintenance of breaking member 124 and the posture of the relative straight inclined in surface of side frame 108; Simultaneously; Be disposed at extension 124d leading section polymer member part 124e leading section and side frame 108 side elastic ground and closely contact, thus, can block the gap 302 between door-plate 116 and the side frame 108 airtightly.
Be used to shown in Fig. 4 to explain with side frame portion as shown in Figure 3 with the variform embodiment of breaking member, along other examples of the cutaway view of the B-B line of Fig. 1.Side frame portion shown in Fig. 4 (a) extends to the side of the door camera bellows side of side frame 108b with the extension 124d of breaking member 124b, be disposed at the leading section that comprises extension 124d part polymer member part 124e side and the camera bellows side of side frame 108b side elastic ground and closely contact.Through this contact, the gap 302 between door-plate 116b and the side frame 108b is by blocking-up airtightly.
Even presence of fire involves near the stop; Side frame portion becomes high temperature with breaking member 124b; Polymer member part 124e thereby the state of affairs that disappear former because of fusing etc.; Because extension 124d is by rubber-like imcombustibility component set-up, so shown in Fig. 4 (b), the side elastic ground of the side of the leading section of the imcombustibility parts of extension 124d part and the camera bellows side of side frame 108b and closely contacting.Through this contact, even under the situation that polymer member part 124e disappears, the gap 302 between door-plate 116b and the side frame 108b is also by blocking-up airtightly.
Use breaking member 124a through being provided with the identical side frame portion of breaking member 124b formation, can block door-plate 116a equally and comprise the gap between the camera bellows portion of side frame 108a with side frame portion as shown in Figure 4.
Be used to shown in Fig. 5 explain with the side frame portion that describes with reference to Fig. 3 with the breaking member shape more different embodiment, along other examples of the cutaway view of the B-B line of Fig. 1.Side frame portion shown in Fig. 5 (a) extends to the side of the door camera bellows side of side frame 108b with the extension 124d of breaking member 124b, and the side of polymer member part 124e that is disposed at the pars intermedia of extension 124d flexibly and closely contacts with the angle of the camera bellows portion of side frame 108b.Through this contact, the gap 302 between door-plate 116b and the side frame 108b is by blocking-up airtightly.Here, at the front end of extension 124d, be formed with button in the part of representing with dotted ellipse and end (hang and end) 124f of portion.
When near fire propagation stop, the stop side of door-plate 116 is compared temperature build-up with hoistway side, produces heal differential in the stop side and the hoistway side of door-plate 116.When becoming this situation, smooth door-plate 116 for example begins to be out of shape to the mode of stop side protrusion.As a result, the part of door-plate 116 is out of shape with the mode of separating with side frame 108.Fig. 5 (b) illustrates this state, and with the compared shown in Fig. 5 (a), the distance between door-plate 116b and the side frame 108b enlarges, and gap 302 enlarges.When the distance of door-plate 116b and side frame 108b expands predetermined value to; Shown in Fig. 5 (b), be formed at side frame portion with the snap portion 124f of the front end of the extension 124d of breaking member 124b and being ended of the door camera bellows side side that is formed at side frame 108b by snap portion 108f button.Snap portion 124f with ended by snap portion 108f button, thus, door-plate 116b can be no longer further from side frame 108b.
At this moment, because have elasticity at extension 124d, so the side of extension 124d flexibly and closely contacts with the angle of the door camera bellows side of side frame 108b, the gap 302 between door-plate 116b and the side frame 108b is by blocking-up airtightly.Moreover; At the state that keeps polymer member part 124e shown in Fig. 5 (b); But under the situation that the state of affairs that polymer member part 124e disappears because of reasons such as fusings takes place, flexibly and closely contact with the angle of the camera bellows side of side frame 108b by the side of the extension 124d of rubber-like imcombustibility component set-up.Through such contact, the gap 302 between door-plate 116b and the side frame 108b is by blocking-up airtightly.
As previously mentioned, side frame portion is set as along the almost total length of the above-below direction of door-plate 116b with breaking member 124b extends continuously, and side frame portion also is set as along the almost total length of the above-below direction of door-plate 116b with the extension 124d of breaking member 124b extends continuously.But the snap portion 124f that is formed at extension 124d needn't be provided with along the almost total length of the above-below direction of door-plate 116b continuously.Also can form one or more snap portion 124f at the key position of extension 124d.Observe the transparent view of side frame portion from the stop side shown in Fig. 6 with breaking member 124b.In the figure, three positions formation snap portion 124f in side frame portion with the extension 124d of breaking member 124b, but this is an example, and the quantity of snap portion 124f can be one or more.
Use breaking member 124a through being provided with the identical side frame portion of breaking member 124b formation, can block door-plate 116a equally and comprise the gap between the camera bellows portion of side frame 108a with side frame portion shown in Figure 5.Simultaneously, door-plate 116a is not separated more than the appointed interval with side frame 108a.
According to this embodiment; Except through the effect that embodiment obtained that describes with reference to Fig. 3 and Fig. 4; Can also the distortion of the door-plate that produces owing to heat be suppressed in the specified limit, and the disengaging that the thermal deformation that prevents by door-plate is caused is useful.
Be used for shown in Fig. 7 the side frame portion that will describe with reference to Fig. 3 (a) carried out with the part of the mode of the extension of breaking member that after changing embodiment describes, along another other examples of the cutaway view of the B-B line of Fig. 1.Extension 124d in the side frame portion shown in Fig. 3 (a) with breaking member 124b, rubber-like polymer member part 124e is only superimposed in side pars intermedia, that under the door closing state, contact with the bight of side frame 108b as extension 124d; Relative therewith; Extension 124d in side frame portion shown in Figure 7 with breaking member 124b; Rubber-like polymer member part 124e except superimposed a side that contacts with the bight of side frame 108b under the door closing state, also superimposed opposition side at extension 124d.That is, side frame portion with the extension 124d of breaking member 124b therebetween portion by 124e clamping of rubber-like polymer member part or encirclement.
Such formation for example can be through making side frame portion with the extension 124d insertion rubber-like polymer member of breaking member 124b.
The side frame portion that is assemblied in door-plate 116a with the extension 124d of breaking member 124b is too: rubber-like polymer member part 124e except superimposed a side that contacts with the bight of side frame 108b under the door closing state, also superimposed opposition side at extension 124d.
Be used for shown in Fig. 8 the side frame portion that will describe with reference to Fig. 5 carried out with the part of the mode of the extension of breaking member that after changing embodiment describes, along another different example of the cutaway view of the B-B line of Fig. 1.Extension 124d in the side frame portion shown in Fig. 5 (a) with breaking member 124b, rubber-like polymer member part 124e is only superimposed in side pars intermedia, that under the door closing state, contact with the bight of side frame 108b as extension 124d; Relative therewith; Extension 124d in the side frame portion shown in Fig. 8 (a) with breaking member 124b; Rubber-like polymer member part 124e except superimposed a side that contacts with the bight of side frame 108b under the door closing state, also superimposed opposition side at extension 124d.That is, side frame portion with the extension 124d of breaking member 124b therebetween portion by 124e clamping of rubber-like polymer member part or encirclement.
Such formation for example can be through making side frame portion with the extension 124d insertion rubber-like polymer member of breaking member 124b.
The state that the part of door-plate 116 is out of shape with the mode of separating with side frame 108 shown in Fig. 8 (b).As illustrated with reference to Fig. 5 (b); When the distance between door-plate 116b and the side frame 108b expands to when wanting predetermined value; Shown in Fig. 8 (b), be formed at side frame portion being ended with the side of the snap portion 124f of the front end of the extension 124d of breaking member 124b and the door camera bellows side that is formed at side frame 108b by snap portion 108f button.End through snap portion 124f and by snap portion 108f button, door-plate 116b can be no longer further from side frame 108b.
On the extension 124d of the side frame portion that is assemblied in door-plate 116a with breaking member 124b; Be too: rubber-like polymer member part 124e except superimposed a side that contacts with the bight of side frame 108a under the door closing state, also superimposed opposition side at extension 124d.
Moreover when door was opened, door-plate 116 moved to cooresponding door camera bellows direction, under the door closing state, separated with side frame 108 with the extension 124d and the polymer member part 124e of breaking member 124 with the side frame portion of side frame 108 closed contacts.When door was closed, door-plate 116 moved to the center direction of door pocket 104, and side frame portion is slightly crooked owing to contacting with corresponding side frame 108 with the extension 124d and the polymer member part 124e of breaking member 124.That is, side frame portion all receives flexure stress with the extension 124d and the polymer member part 124e of breaking member 124 when door is closed.Therefore, it is desirable to: employed polymer member part 124e goes up having the suitable elastomeric while with the extension 124d of breaking member 124 in side frame portion, also has suitable abrasion performance and nerve.
(the 1-3. upper frame is used blocking-up portion)
Then, explain in the formation in each gap between blocking-up door-plate 116 and the upper frame 110 under door-plate 116 closing state being used for reference to Fig. 9.Be used for shown in Fig. 9 as the diagram of explaining along a formation example of the cutaway view of the C-C line of Fig. 1, that be used to block the gap between door-plate 116a and the upper frame 110.Moreover, because identical, therefore omit diagram and explanation with the formation that is used to block the gap between door-plate 116b and the upper frame 110.Under door-plate 116 closing state, there is gap between door-plate 116a and the upper frame 110 by reference symbol 902 expressions.In order to block this gap 902, the assembling upper frame is with breaking member 126.Upper frame is formed by stacking by the rubber-like polymer member at least a portion of rubber-like imcombustibility parts and the one side at least that is disposed at the imcombustibility parts with breaking member 126.
Upper frame is fixed in the hoistway side of upper frame 110 through the base end part 126c of this breaking member 126 with breaking member 126.Upper frame is closely fixing with the mode that does not form the gap between this breaking member 126 and the upper frame 110 with breaking member 126.For example, through sticker metal pressing plate 904 is adhered to the base end part 126c of breaking member 126, being situated between closely is fixedly linked on upper frame 110 by stop screw 906 with base end part 126c that is adhered and pressing plate 904 integratedly.Here, the part of the base end part 126c of breaking member 126 is integrally formed, by aforementioned rubber-like imcombustibility component set-up.Upper frame extends along the almost total length of the left and right directions of upper frame 110 with breaking member 126 continuously, for example, is situated between by stop screw 906, and the spacing by appointment closely is fixed in upper frame 110 through base end part 124c.
Upper frame is integrally formed with the upside and the base end part 126c of breaking member 126, becomes the extension 126d that extends obliquely to door-plate 116a side direction top from base end part 126c.Extension 126d has the effect of spring by the rubber-like imcombustibility component set-up that extends to door-plate 116a side from base end part 126c.Be built up the part 126e that is made up of the rubber-like polymer member at extension 126d, this part 126e is positioned at least a portion as a relative side with door-plate 116a of the part of this extension 126d.As shown in Figure 9; Upper frame is with the extension 126d maintenance of breaking member 126 and the posture of the surperficial relative tilt of door-plate 116a; Simultaneously; For example front-end edge portion is crooked to curve circular-arc mode backward, and the side of polymer member part 126e that under the door closing state, is disposed at the front end sidepiece of extension 126d flexibly and closely contacts with the upper face of door-plate 116a.Through this contact, the gap 902 between upper frame 110 and the door-plate 116a is by blocking-up airtightly.
Near the fire propagation stop, upper frame becomes high temperature with breaking member 126, and polymer member part 126e also maybe be because of former thereby disappearances such as fusings.Even such state of affairs takes place; Because extension 126d is by rubber-like imcombustibility component set-up; Same with the extension 124d of breaking member with aforementioned side frame portion, the side of the front-end edge portion of extension 126d is with the surface elasticity ground of door-plate 116a and closely contact.Through this contact, even under the situation that polymer member part 126e disappears, the gap 902 between upper frame 110 and the door-plate 116a is also by blocking-up airtightly.
Even become under the hi-heat situation with breaking member 126 at upper frame, the gap between upper frame 110 and the door-plate 116b is also blocked through same formation airtightly.
Moreover, record and narrate with breaking member 124 fronts about side frame portion, and can adopt various shape and mode with breaking member 126 as upper frame, be not limited to shape shown in Figure 9 and mode.For example; As through Fig. 7 and side frame portion shown in Figure 8 with breaking member 124; Can be at the extension 126d configuration rubber-like polymer member part 126e of upper frame with breaking member 126; Make its except superimposed a side that contacts with the surface of door-plate 116 under the door closing state, also superimposed opposition side at extension 126d.That is, upper frame is constituted by 126e clamping of rubber-like polymer member part or encirclement with the extension 126d of breaking member 126.Such formation for example can be through making upper frame with the extension 126d insertion rubber-like polymer member of breaking member 126.
In addition; In embodiment shown in Figure 9, upper frame is with the extension 126d maintenance of breaking member 126 and the posture of the surperficial relative tilt of door-plate 116, simultaneously; Front-end edge portion is crooked to curve circular-arc mode backward; The side of polymer member part 126e that is disposed at the front end sidepiece of extension 126d flexibly and closely contacts with the upper face of door-plate 116, and thus, the gap 902 between upper frame 110 and the door-plate 116 is by blocking-up airtightly.But the gap 902 of blocking airtightly between upper frame 110 and the door-plate 116 through breaking member is not limited to aforementioned manner.For example; Upper frame is with the extension 126d maintenance of breaking member 126 and the posture of the relative straight inclined in surface of door-plate 116; Simultaneously; The side of polymer member part 126e of side that is disposed at the pars intermedia of extension 126d flexibly and closely contacts with the upper face of door-plate 116, thus, can block the gap 902 between upper frame 110 and the door-plate 116 airtightly.
According to the embodiment of above explanation, under door-plate 116 closing state,, can limit cigarette and flame and flow into hoistway side through this gap from the stop side even when high temperature, also can block the gap between upper ledge 110 and each door-plate 116.
In addition, for example through sticker pressing plate 904 is assemblied in the base end part 126c of upper frame with breaking member 126 in advance, under this state, base end part 126c is fixed in upper frame 110 through stop screw 906.Therefore, through strengthening base end part 126c with pressing plate 904, the distortion of base end part 126c is prevented, and in upper frame 110, upper frame is with being blocked between breaking member 126 and the upper frame 110 with breaking member 126 close fit for upper frame.
Moreover, when door- plate 116a, 116b open and close, the top of each door-plate 116 and superimposed at upper frame with the polymer member part 126e moving contact on the extension 126d of parts 126.Therefore, it is desirable to: be used for upper frame with the parts of the polymer member part 126e of breaking member 126 having the suitable elastomeric while, also have suitable slyness property and abrasion performance.
(1-4. sill portion uses blocking-up portion)
Then, explain in the formation in each gap between blocking-up door-plate 116 and the sill 106 under door-plate 116 closing state being used for reference to Figure 10.Be used for shown in Figure 10 as the diagram of explaining along a formation example of the cutaway view of the D-D line of Fig. 1, that be used to block the gap between door-plate 116a and the sill 106.Moreover, because be used to block the formation in the gap between door-plate 116b and the sill 106 and be used to block the formation in the gap between door-plate 116a and the sill 106 identical, therefore omit diagram and explanation.
On sill 106 along its length, promptly the switching direction of door forms guiding groove 1008.The boots 122a that leads that is assemblied in the bottom of door-plate 116a inserts in the guiding groove 1008, and door-plate 116a opens and closes along guiding groove 1008.Moreover, in most cases, be formed for discharging the discharge orifice (not illustrating) of foreign matters such as rubbish in the bottom surface of guiding groove 1008.
Under door-plate 116 closing state, there is gap between door-plate 116a and the sill 106 by reference symbol 1002 expressions.In order to block this gap 1002, be equipped with sill portion at door-plate 116a and use breaking member 128a.Sill portion is formed by stacking by the rubber-like polymer member at least a portion of rubber-like imcombustibility parts and the one side at least that is disposed at the imcombustibility parts with breaking member 128a.
The underbeam 1010 of door-plate 116a is fixed in sill portion through the base end part 128c of this breaking member 128a with breaking member 128a.Sill portion is closely fixing with the mode that does not form the gap between this breaking member 128a and the underbeam 1010 with breaking member 128a.For example, metal pressing plate 1004 is adhered to the base end part 128c of breaking member 128a, base end part 128c that is adhered and pressing plate 1004 closely is fixedly linked on integratedly the underbeam 1010 of door-plate 116 through stop screw 1006 through sticker.Here, the part of the base end part 128c of breaking member 128a is integrally formed, by aforementioned rubber-like imcombustibility component set-up.
Sill portion extends along the almost total length of the left and right directions of the bottom of door-plate 116a with breaking member 128a continuously, for example, is situated between by stop screw 1006, by the spacing of appointment, closely is fixed in the underbeam 1010 of door-plate 116a through base end part 128c.
Sill portion is integrally formed with lower side and the base end part 128c of breaking member 128a, becomes the extension 128d that extends to sill 106 sides from base end part 128c.Extension 128d has the effect of spring by the rubber-like imcombustibility component set-up that begins to extend from base end part 128c, and said base end part 128c is by rubber-like imcombustibility component set-up.Be built up the part 128e that is made up of the rubber-like polymer member at extension 128d, this part 128e is disposed at as the part of this extension 128d and at least a portion sill 106 relative sides.Shown in figure 10; Sill portion is with the extension 128d maintenance of breaking member 128a and the posture of the top relative tilt of sill 106; Simultaneously; For example front-end edge portion is crooked to curve circular-arc mode backward, and the side of polymer member part 128e of leading section that is disposed at extension 128d is with the flexibly top of sill 106 and closely contact.Through this contact, the gap 1002 between door-plate 116a and the sill 106 is by blocking-up airtightly.
As previously mentioned, form the discharge orifice that the discharge foreign matter is used in the bottom surface of the guiding groove of being located at sill 106 1008 sometimes.But; Shown in figure 10; Sill portion with breaking member 128a than the position that forms guiding groove 1008 more near a side of stop with contact and block gap 1002 above the sill 106; The discharge orifice that can limit from the cigarette of stop side and the flame bottom surface through being formed at guiding groove 1008 thus, flows in the hoistway.
Near the fire propagation stop, sill portion becomes high temperature with breaking member 128a, and polymer member part 128e also maybe be because of former thereby disappearances such as fusings.Even such state of affairs takes place, because extension 128d is by rubber-like imcombustibility component set-up, the side of the leading section of extension 128d is with the flexibly top of sill 106 and closely contact.Through this contact, even under the situation that polymer member part 128e disappears, the gap 1002 between door-plate 116a and the sill 106 is also by blocking-up airtightly.
Moreover, record and narrate with breaking member 124 fronts about side frame portion, and can adopt various shape and mode with breaking member 128 as sill portion, be not limited to shape shown in Figure 10 and mode.For example; As through Fig. 7 and side frame portion shown in Figure 8 with breaking member 124; Can be in sill portion with the extension 128d of breaking member 128 configuration rubber-like polymer member part 128e; Make its except superimposed with a side that contacts above the sill 106, also superimposed on the opposition side of extension 128d.That is, sill portion is constituted by 128e clamping of rubber-like polymer member part or encirclement with the extension 128d of breaking member 128.Such formation for example can be through making sill portion with the extension 128d insertion rubber-like polymer member of breaking member 128.
In addition; In embodiment shown in Figure 10, sill portion is with the extension 128d maintenance of breaking member 128 and the posture of the top relative tilt of sill 106, simultaneously; Front-end edge portion is crooked to curve circular-arc mode backward; The side of polymer member part 128e of leading section that is disposed at extension 128d is with the flexibly top of sill 106 and closely contact, and thus, the gap 1002 between door-plate 116 and the sill 106 is by blocking-up airtightly.But the gap 1002 of blocking airtightly between door-plate 116 and the sill 106 through breaking member is not limited to aforementioned manner.For example; Sill portion is with the extension 128d maintenance of breaking member 128 and the posture of the top relative straight inclined of sill 106; Simultaneously; The leading section of polymer member part 128e of side of pars intermedia that is disposed at extension 128d is with the flexibly top of sill 106 and closely contact, and thus, can block the gap 1002 between door-plate 116 and the sill 106 airtightly.
According to the embodiment of above explanation, under door-plate 116 closing state,, can limit cigarette and flame and flow into hoistway side through this gap from the stop side even when high temperature, also can block the bottom of door-plate 116 and each gap between the sill 106.
In addition, as previously mentioned, for example in advance pressing plate 1004 is assemblied in the base end part 128c of sill portion with breaking member 128, under this state, base end part 128c is fixed in the underbeam 1010 of door-plate 116 through stop screw 1006.Therefore, through strengthening base end part 128c with pressing plate 1004, the distortion of base end part 128c is prevented, and simultaneously, sill portion is with the underbeam 1010 of breaking member 128 close fit in door-plate 116, and sill portion is with being blocked between breaking member 128 and the door-plate 116.
Moreover, when door-plate 116 opens and closes, superimposed in sill portion with polymer member part 128e on the extension 128d of parts 128a and moving contact above the sill 106.Therefore, it is desirable to: will having suitably, the elastomeric material that has suitable slyness property and abrasion performance simultaneously is used for upward employed polymer member part 128e of extension 128d.
(the door shield portion of 1-5. door uses blocking-up portion)
Then, with reference to Figure 11 to be used for closing at door-plate 116, the formation in gap under the state that the side edge part of each door-plate 116a and door-plate 116b is met and discussed each other between the side edge part of blocking-up door-plate 116a and door-plate 116b explains.Be used for shown in Figure 10 as the diagram of explaining along the formation in the gap between a door shield portion example of the cutaway view of the E-E line of Fig. 1, that be used to block a pair of door-plate 116.Under door-plate 116a and door-plate 116b closing state, between the side edge part (door shield portion) of these door-plates 116, there is gap by reference symbol 1102 expressions.In order to block this gap 1102, assemble door shield portion respectively with breaking member 130a and 130b at door-plate 116a and door-plate 116b.Door shield portion is formed by stacking by the rubber-like polymer member at least a portion of rubber-like imcombustibility parts and the one side at least that is disposed at the imcombustibility parts with breaking member 130.Such as from Figure 11 knowledge, there is symmetrical relation in door shield portion with breaking member 130a and 130b, can form identical formation, therefore, in following explanation, uses breaking member 130a to record and narrate as the center with door shield portion.
Door-plate 116a is fixed in the base end part 130c of breaking member 130a through this breaking member 130a in door shield portion.Door shield portion is closely fixing with the mode that does not form the gap between this breaking member 130a and the door-plate 116a with breaking member 130a.Here, the part of the base end part 130c of breaking member 130a is by rubber-like imcombustibility component set-up.Door shield portion extends along the almost total length of the above-below direction of door-plate 116a with breaking member 130a continuously, and for example, by stop screw, the spacing by appointment closely is fixed in door-plate 116a through base end part 130c.
Door shield portion is integrally formed with a lateral margin side and the base end part 130c of breaking member 130a, becomes the extension 130d by rubber-like imcombustibility component set-up that extends to the door shield side from base end part 130c.Extension 130d has the effect of spring.Be built up the part 130e that is made up of the rubber-like polymer member at extension 130d, this part 130e is disposed at the door shield side of extension 130d.Shown in figure 11; Door shield portion is with the extension 130d maintenance of breaking member 130b and the posture of the surperficial relative tilt of door-plate 116a; Simultaneously; For example crooked to curve circular-arc mode backward, under the situation that door is closed, be disposed at extension 130d polymer member part 130e side and the polymer member part 130e of the extension 130d of the door-plate 116b that is disposed at same formation side elastic ground and closely contact.Through this contact, the gap 1102 between door-plate 116a and the door-plate 116b is by blocking-up airtightly.Door shield portion comprises the parts such as part pars intermedia respect to one another of extending to these door shield sides with the extension 130d of breaking member 130a and door shield portion with the extension 130d of breaking member 130b.Moreover, in the illustrated embodiment, in order to reduce the harm under the situation that the elevator user clamped by door-plate, be provided with hollow bulb in breaking member 130 in each door shield portion.
Near the fire propagation stop, door shield portion becomes high temperature with breaking member 130a, 130b, and polymer member part 130e also maybe be because of former thereby disappearances such as fusings.Even such state of affairs takes place; Because extension 130d is by rubber-like imcombustibility component set-up; So the side of the part of extending to the door shield side each other flexibly and closely contact, wherein should comprise the parts such as imcombustibility parts part pars intermedia respect to one another of a pair of extension 130d to part that the door shield side is extended.Through this contact, even under the situation that polymer member part 130e disappears, the gap 1102 between door-plate 116a and the door-plate 116b is also by blocking-up airtightly.
Moreover, can adopt various shape and mode as door shield portion with breaking member 130, be not limited to shape shown in Figure 11 and mode.For example; Can be in door shield portion with the extension 130d of breaking member 130 configuration rubber-like polymer member part 130e; Make its except superimposed with the door shield side of the part of the imcombustibility parts that extend to the door shield side on, also superimposed on the opposition side of extension 130d.That is, door shield portion is constituted by 130e clamping of rubber-like polymer member part or encirclement with the extension 130d of breaking member 130.Such formation for example can be made through door shield portion is inserted the rubber-like polymer member with the part of the imcombustibility parts of the extension 130d of breaking member 130.
According to the embodiment of above explanation, under door-plate 116 closing state,, can limit cigarette and flame and flow into hoistway side through this gap from the stop side even when high temperature, also can block the gap between door-plate 116a and the door-plate 116b.
According to the embodiment under the situation of the double-open type door of above explanation; Gap between the door shield portion of gap between the gap between the gap between each of elevator floor stops layer door-plate 116 and the side frame 108, each layer door-plate 116 and the upper frame 110, each layer door-plate 116 and the sill 106 and a pair of layer door-plate 116 is blocked with breaking member 130 with breaking member 128 and door shield portion with breaking member 126, sill portion with breaking member 124, upper frame by the side frame portion that comprises incombusible material respectively; Under the situation of the arrival layer presence of fire of elevator, cigarette can be limited and flame flows into hoistway from elevator floor stops.Therefore, can when suppressing fire expansion, prevent that cigarette and flame from arriving layer diffusion to other.
In addition, the extension of each breaking member has the function of spring, therefore, even be disposed at extension contact part the polymer member part because of with remove contacting of object and wear and tear or disappear, also can block cigarette and flame.
In addition, each breaking member constitutes succinct, therefore also can force down cost.
And, till playing a role, also need opening time unlike the device that kind of taking precautions against natural calamities of using curtain plate in the past, can instantaneous blocking-up cigarette and flame.In addition, each breaking member can be arranged at the user cannot see touch less than the position, therefore can not diminish the attractive in appearance of elevator floor stops, do not worry bringing harm to the elevator user.
(the 2. embodiment under the situation of single opened door)
Then, with reference to Figure 12 to Figure 21 the embodiment of the situation of single opened door is explained.At this, in following explanation, describe as the situation of an example to two-fold single opened door.
(the formation summary of 2-1. embodiment)
Shown in Figure 12 from hoistway side observe embodiment of the present invention two-fold single opened elevator floor stops device one the example front elevation; Shown in Figure 13 along the cutaway view of the F-F line of Figure 12.Here, Figure 12 and Figure 13 are the figure of door-plate closed condition.Boarding portion is surrounded with sill 106 by the door pocket 104 of the peristome that is assemblied in building walls 102.Door pocket 104 by and a pair of side frame 108a and the 108b that laterally arrange of the up-down direction of elevator, be arranged at side frame 108a, 108b top between upper ledge 110 constitute, form a door shape.The opening that is surrounded by door pocket 104 and sill 106 becomes boarding portion.
Under the situation of aforementioned double-open type door, on the same plane parallel with building walls 102 that a pair of door- plate 116a, 116b are disposed at elevator floor stops, door- plate 116a, 116b move with identical speed to opposite directions, and thus, boarding portion opens and closes.On the other hand; In the embodiment under the situation of the following two-fold single opened door that describes; Shown in figure 13, door- plate 116a, 116b are configured to be the AM/BAM scalariform from boarding direction (grasp and fall direction) observation, and door- plate 116a, 116b move to same direction with different speed; Thus, boarding portion opens and closes.In this, the situation with the double-open type door is different.
In this embodiment, door- plate 116a, 116b move to the left direction of figure from Figure 12 and door closing state shown in Figure 13 jointly, and thus, door is opened.In Figure 12 and Figure 13, the left field of door-plate 116a is corresponding with the door camera bellows among the figure of the hoistway side of building walls 102.In this application, the side frame 108a among Figure 12 and Figure 13 is called a side frame of camera bellows side.On the contrary, the state that door- plate 116a, 116b open from door moves to the right direction of figure jointly, and thus, door is closed.Side frame 108b among Figure 12 and Figure 13 is the side frame of door shield side.When door opened and closed, door-plate 116a compared with low speed with door-plate 116b and moves sometimes, therefore, is called slow door, and door-plate 116b is called high-speed door.When two-fold single opened door opens and closes, the moving velocity of slow door be about high-speed door moving velocity 1/2.
In the embodiment under the situation of two-fold single opened door, door- plate 116a, 116b are configured to observe from the up-down direction and are the AM/BAM scalariform, and therefore, the configuration that the upper frame 110 of sill 106 and door pocket 104 also becomes with door-plate constitutes accordingly.In this, with the situation of aforementioned double-open type door under embodiment different.Formation about sill 106 will be recorded and narrated at the back in detail, 110 of upper frames comprise with figure in the corresponding left side of door-plate 116a the interval 110a in prostatitis and with the interval 110b of the rank rear on the corresponding right side of door-plate 116b.
The same with the situation of aforementioned double-open type door; Even under the situation that door-plate 116 cuts out; Between door-plate 116a and side frame 108a, door-plate 116b and side frame 108b, door-plate 116a and 116b and upper ledge 110, door-plate 116a and 116b and sill 106 and door-plate 116a and 116b, also there is the minim gap about number mm; When fire took place, cigarette or flame maybe be through these gaps from stop side direction hoistway side inflows.The back will be elaborated, and in this embodiment, in order to limit cigarette or flame from stop side inflow hoistway side, be equipped with the occluding device that is made up of the breaking member that is disposed at key position.Promptly; The side frame portion that on door-plate 116a, is equipped with a camera bellows side uses breaking member 1228a with breaking member 1224 and sill portion, even these breaking members are blocked respectively in the door-plate 116a that also exists under the door-plate closing state and the side frame 108a of door camera bellows side and the gap between the sill 106.The side frame portion that on door-plate 116b, is equipped with the door shield side with breaking member 1225a, sill portion with overlapping of breaking member 1228b and door with breaking member 1230, these breaking members are blocked the gap between the 108b of side frame portion, sill 106 and the door-plate 116a of door-plate 116b and door shield side respectively.In addition, be equipped with upper frame with breaking member 1226, even this breaking member blocking-up is in upper frame 110 that also exists under the door-plate closing state and the gap between door-plate 116a and the 116b at upper frame 110.Have, the side frame portion that is equipped with the door shield side at the side frame 108b of door shield side uses breaking member 1225b again, even side frame 108b that this breaking member blocking-up also exists under the door-plate closing state and the gap of door-plate 116b.Below, the blocking part of blocking each gap is not described.Here, below the figure of explanation and reference is about the situation under door-plate 116a and the 116b closed condition.Moreover, not a plurality of but under the situation of simple gate single opened door, overlapping of door is N/Rs with breaking member 1230 at the door-plate number.Below, the blocking part of blocking each gap is not described, but, put down in writing its purport, and only do succinct explanation about adopting the blocking-up portion with the same formation of aforementioned double-open type door.
(the side frame portion of 2-2. door camera bellows side uses blocking-up portion)
The side frame portion of door camera bellows side with blocking-up portion can adopt with (1-2) in side frame portion under the situation that be illustrated with reference to Fig. 3 to Fig. 8, the double-open type door with the identical formation of blocking-up portion.With reference to Figure 14, explain in an example of the formation in the side edge part of the door camera bellows side of blocking-up door-plate 116a under door-plate 116 closing state and the gap between the side frame 108a being used for.Be used for shown in Figure 14 to as along an example of the cutaway view of the G-G line of Figure 12, be used to block door-plate 116a with a camera bellows portion that comprises side frame 108a between the diagram explained of the formation in gap.Opposite about the formation shown in this figure and Fig. 3, but identical in fact with formation shown in Figure 3.Under door-plate 116 closing state, to be present in door-plate 116a and to comprise the gap between the door camera bellows portion of side frame 108a in order to block by reference symbol 1402 expressions, the side frame portion of assembling door camera bellows side is with breaking member 1224.The side frame portion of door camera bellows side is formed by stacking by the rubber-like polymer member at least a portion of rubber-like imcombustibility parts and the one side at least that is disposed at the imcombustibility parts with breaking member 1224.
The side edge part of the door camera bellows side of door-plate 116a is fixed in the side frame portion of door camera bellows side through the base end part 1224c by rubber-like imcombustibility component set-up with breaking member 1224.The side frame portion of door camera bellows side is closely fixing with the mode that does not form the gap between this breaking member 1224 and the door-plate 116a with breaking member 1224.For example, metal pressing plate 1404 is adhered to the base end part 1224c of breaking member 1224b, base end part 1224c that is adhered and pressing plate 1404 closely is fixedly linked on integratedly the side edge part of door-plate 116 through stop screw 1406 through sticker.The side frame portion of door camera bellows side extends along the almost total length of the above-below direction of door-plate 116a with breaking member 1224 continuously, for example, is situated between by stop screw 1406, and the spacing by appointment closely is fixed in door-plate 116a through base end part 1224c.
The side frame portion of door camera bellows side is integrally formed with a lateral margin side and the base end part 1224c of breaking member 1224, becomes the extension 1224d that extends to the configuration side of side frame 108a from base end part 1224c.Extension 1224d has the effect of spring by the rubber-like imcombustibility component set-up that begins to extend from base end part 1224c, and said base end part 1224c is by rubber-like imcombustibility component set-up.Be built up the part 1224e that is made up of the rubber-like polymer member at extension 1224d, this part 1224e is disposed at least a portion as a relative side with side frame 108a of the part of this extension 1224d.Shown in figure 14; The side frame portion of door camera bellows side is with the extension 1224d maintenance of breaking member 1224 and the posture of the surperficial relative tilt of side frame 108a; Simultaneously; For example crooked to curve circular-arc mode backward, the side of polymer member part 1224e that under the door closing state, is disposed at the pars intermedia of extension 1224d flexibly and closely contacts with the bight of side frame 108a.Through this contact, the gap 1402 between door-plate 116a and the side frame 108a is by blocking-up airtightly.
Near the fire propagation stop, the side frame portion of door camera bellows side becomes high temperature with breaking member 1224, and polymer member part 1224e also maybe be because of former thereby disappearances such as fusings.Even such state of affairs takes place, identical with the explanation of carrying out with reference to Fig. 3 (b), because extension 1224d is by rubber-like imcombustibility component set-up, so the side of the pars intermedia of extension 1224d flexibly and closely contacts with the bight of side frame 108a.Through this contact, even under the situation that polymer member part 1224e disappears, the gap 1402 between door-plate 116a and the side frame 108a is also by blocking-up airtightly.
Embodiment according to above explanation; Under door-plate 116 closing state; Even when high temperature, also can block the side edge part and the gap between the side frame 108a of the door camera bellows side of door-plate 116a, can limit cigarette and flame from the stop side through this gap inflow hoistway side.
In addition, through sticker pressing plate 1404 is assemblied in the base end part 1224c of the side frame portion of a camera bellows side with breaking member 1224 in advance, under this state, base end part 1224c is fixed in the side edge part of door-plate 116a through stop screw 1406.Therefore; Through strengthening base end part 1224c with pressing plate 1404; The distortion of base end part 1224c is prevented, and in the side edge part of door-plate 116a, the side frame portion of door camera bellows side is with being blocked between breaking member 1224 and the door-plate 116a with breaking member 1224 close fit in the side frame portion of door camera bellows side.
Moreover; In embodiment shown in figure 14, the side frame portion of door camera bellows side is with the extension 1224d maintenance of breaking member 1224 and the posture of the surperficial relative tilt of side frame 108a, simultaneously; Crooked to curve circular-arc mode backward; The side of polymer member part 1224e that is disposed at the pars intermedia of extension 1224d flexibly and closely contacts with the bight of side frame 108a, and thus, the gap 1402 between door-plate 116a and the side frame 108a is by blocking-up airtightly.But the gap 1402 of blocking airtightly between door-plate 116a and the side frame 108a through breaking member is not limited to aforementioned manner.As the double-open type door being described with reference to Fig. 3 to Fig. 5; For example; The side frame portion of door camera bellows side keeps the posture with the relative straight inclined in surface of side frame 108a with the extension 1224d of breaking member 1224, simultaneously, be disposed at extension 1224d leading section polymer member part 1224e leading section and side frame 108a side elastic ground and closely contact; Thus, can block gap 1402 between door-plate 116a and the side frame 108a airtightly.
That is the side frame portion of door camera bellows side that, also can be in the single opened door with the side frame portion under the situation of employing in the blocking-up portion and the double-open type door that is illustrated with reference to Fig. 4 with the identical formation of blocking-up portion.In this case, be disposed at the side frame portion that comprises a camera bellows side with the side elastic ground of the side of the polymer member part of the part of the leading section of the extension of breaking member 1224 and the camera bellows side of side frame 108a and closely contact.Even in this case; Identical with embodiment shown in Figure 14; The side frame portion of door camera bellows side flexibly and closely contacts with the side frame 108a of breaking member 1224 with door camera bellows side, thus, becomes high temperature even the side frame portion of door camera bellows side takes place with breaking member 1224; The polymer member part is because of the such state of affairs of reasons such as fusing disappearance, and the gap between door-plate 116a and the side frame 108a also will be by blocking-up airtightly.
Have again, the side frame portion of door camera bellows side that also can be in the single opened door with the side frame portion under the situation of the employing of blocking-up portion and the double-open type door that is illustrated with reference to Fig. 5 and Fig. 6 with the identical formation of blocking-up portion.
That is, the side frame portion of door camera bellows side extends to the side of the door camera bellows side of side frame 108a with the extension by rubber-like imcombustibility component set-up of breaking member 1224, at the front end formation snap portion of extension.At the pars intermedia of extension, polymer member partly is disposed at the face of the side frame side of extension.Under door-plate 116 closing state, the side of polymer member part 1224e flexibly and closely contacts with the angle of the door camera bellows side of side frame 108a.
As previously mentioned, when near fire propagation stop, the stop side of door-plate 116 is compared temperature build-up with hoistway side, produces heal differential in the stop side and the hoistway side of door-plate 116.When becoming this situation, smooth door-plate 116 for example begins to be out of shape to the mode of stop side protrusion.As a result, the part of door-plate 116 is out of shape with the mode of separating with side frame 108.When the distance of door-plate 116a and side frame 108a expanded predetermined value to, the side frame portion that is formed at a camera bellows side was with the snap portion of the front end of the extension of breaking member 1224 and being ended by snap portion 108f button of the door camera bellows side side that is formed at side frame 108a.Snap portion with ended by snap portion 108f button, thus, door-plate 116a can be no longer further from side frame 108a.
At this moment, because have elasticity at extension, so the side of extension flexibly and closely contacts with the angle of the door camera bellows side of side frame 108a, the gap between door-plate 116a and the side frame 108a is by blocking-up airtightly.Under the situation that the state of affairs that polymer member part disappears because of reasons such as fusings takes place, flexibly and closely contact with the angle of the camera bellows side of side frame 108a by the side of the extension of rubber-like imcombustibility component set-up.Through such contact, the gap 1402 between door-plate 116a and the side frame 108a at ordinary times and near the fire propagation stop time all by blocking-up airtightly.
As previously mentioned; The side frame portion of door camera bellows side is set as along the almost total length of the above-below direction of door-plate 116a with breaking member 1224 extends continuously, and the side frame portion of a camera bellows side also is set as along the almost total length of the above-below direction of door-plate 116a with the extension of breaking member 1224 extends continuously.But as with reference to Fig. 6 explanation, the snap portion that is formed at extension needn't be provided with along the almost total length of the above-below direction of door-plate 116a continuously.Also can form one or more snap portions at the key position of extension.
According to this embodiment, the effect in aforementioned embodiments, can also the distortion of the door-plate that produces owing to heat be suppressed in the specified limit, and the disengaging that the thermal deformation that prevents by door-plate is caused is useful.
In addition, also can adopt side frame portion under the situation with the double-open type door that is illustrated with reference to Fig. 7 and Fig. 8 with the identical formation of blocking-up portion.Promptly; With polymer member partly be configured to except superimposed as the side frame portion of door camera bellows side with the part of the extension of breaking member 1224, a side that contacts with the arbitrary portion of side frame 108a under the door closing state, also superimposed on the opposition side of extension.In such formation, the side frame portion of door camera bellows side is wherein a part of by part clamping of rubber-like polymer member or encirclement with the extension of breaking member 1224.Such formation for example, can be made with the extension insertion rubber-like polymer member of breaking member 1224 through the side frame portion with door camera bellows side.
Moreover when door was opened, door-plate 116a moved to door camera bellows direction, under the door closing state, partly separated with side frame 108a with the extension and the polymer member of breaking member 1224 with the side frame portion of the door camera bellows side of side frame 108a closed contact.When door was closed, door-plate 116a moved to the center direction of door pocket 104, the side frame portion of door camera bellows side with the extension of breaking member 1224 and polymer member partly through having contacted a little bending with side frame 108a.That is, when door was closed, the side frame portion of door camera bellows side partly received the stress from side frame 108a with the extension and the polymer member of breaking member 1224.Therefore, it is desirable to: with the side frame portion of door camera bellows side with the polymer member part of the extension collapsed configuration of breaking member 1224 having the suitable elastomeric while, have suitable abrasion performance and nerve.
(the side frame portion of 2-3. door shield side uses blocking-up portion)
With reference to Figure 15, explain in an example of the formation in the side edge part of the door shield side of blocking-up door-plate 116b under door-plate 116 closing state and the gap between the side frame 108b being used for.Be used for shown in Figure 15 as the diagram of explaining along the formation in the gap between door shield portion example, that be used to block door-plate 116b and comprise side frame 108b of the cutaway view of the H-H line of Figure 12.In the embodiment shown in this figure, door shield plate 1508 closely is fixed in side frame 108b, the side edge part of door- plate 116b and 1508 collisions of door shield plate when door is closed.Under the door closing state, in order to block the gap that is present between door-plate 116b and the door shield plate 1508 by reference symbol 1502 expression, respectively in the side frame portion of door-plate 116b and door shield plate 1508 assembling door shield sides with breaking member 1225a and 1225b.The side frame portion of door shield side is formed by stacking by the rubber-like polymer member at least a portion of rubber-like imcombustibility parts and the one side at least that is disposed at the imcombustibility parts with breaking member 1225a and 1225b.
The side frame portion of door shield side with breaking member 1225a and 1225b can adopt with the situation that is recorded in the double-open type door under embodiment (the door shield portion of 1-5. door uses blocking-up portion) in the door shield portion of double-open type door usefulness with breaking member 130a and the identical formation of 130b.The side frame portion of the door shield side under the situation of single opened door with blocking-up portion with under the situation of double-open type door the door door shield portion with blocking-up portion the formation on very big difference be: the side frame portion of the door shield side under the situation of single opened door is assemblied in the side frame of door shield plate or door shield side with a side of breaking member 1225, and is not assemblied in door-plate.
The side frame portion of door shield side comprises base end part 1225c that is used to install this breaking member and the extension 1225d that extends to the door shield side from base end part 1225c with breaking member 1225a and 1225b.Base end part 1225c and extension 1225d be by rubber-like imcombustibility component set-up, and be integrally formed.Extension 1225d has the effect of spring.Be built up the part 1225e door shield side that is disposed at extension 1225d, that constitute by the rubber-like polymer member at extension 1225d.Hollow bulb is set in the side frame portion of each door shield side in breaking member 1225.
The side frame portion of door shield side with breaking member 1225a and 1225b respectively with and door-plate 116b between and and door shield plate 1508 between do not produce the gap mode, closely be fixed in door-plate 116b and door shield plate 1508 through each base end part 1225c.The side frame portion of door shield side extends along the almost total length of the above-below direction of door-plate 116b with breaking member 1225a continuously, for example is situated between by stop screw, and the spacing by appointment closely is fixed in door-plate 116b through base end part 1225c.The side frame portion of door shield side extends along the almost total length of the above-below direction of door shield plate 1508 is interval with breaking member 1225b continuously, for example, is situated between by sticker and bolt, closely is fixed in door shield plate 1508 through base end part 1225c.
Shown in figure 15; The side frame portion of door shield side is integrally formed with extension 1225d and the cooresponding base end part 1225c of breaking member 1225a and 1225b; The posture that keeps relative tilt respectively with the surface of the hoistway side of door-plate 116b and door shield plate 1508; Simultaneously; For example crooked to curve circular-arc mode backward, the side frame portion that under the door closing state, is disposed at the door shield side respectively flexibly and closely contacts with the side of the polymer member part 1225e of the extension 1225d of breaking member 1225a and 1225 each other.Through this contact, the gap 1502 between door-plate 116b and the door shield plate 1508 is by blocking-up airtightly.The side frame portion of door shield side comprises the part pars intermedia respect to one another that extends to these door shield sides with the side frame portion of the extension 1225d of breaking member 1225a and door shield side with the extension 1225d of breaking member 1225b.
Even presence of fire involves near the stop; The side frame portion of door shield side becomes high temperature with breaking member 1225a, 1225b; Polymer member part 1225e thereby the state of affairs that disappear former because of fusing etc.; Because extension 1225d is by rubber-like imcombustibility component set-up, so the side of the part of extending to the door shield side that comprises imcombustibility parts part pars intermedia respect to one another of a pair of extension 1225d each other flexibly and closely contact.Through this contact, even under the situation that polymer member part 1225e disappears, the gap 1502 between door-plate 116b and the door shield plate 1508 is also by blocking-up airtightly.
Moreover, can adopt multiple shape and mode as the side frame portion of door shield side with breaking member 1225, and be not limited to shape shown in Figure 15 and mode.For example; On the extension 1225d of side frame portion with breaking member 1225 of door shield side; Can being configured to rubber-like polymer member part 1225c on the door shield side of superimposed part at the imcombustibility parts that extend to the door shield side, also superimposed on the opposition side of extension 1225d.That is, can adopt the formation of the side frame portion of door shield side being carried out clamping or encirclement with the extension 1225d of breaking member 1225 through rubber-like polymer member part 1225e.
Moreover, in the above embodiment that is illustrated, door shield plate 1508 is set at side frame 108b, but also can adopt door shield plate 1508 is not set but when door is closed the formation of the side edge part of the side edge part of door-plate 116b and side frame 108b collision.In this case, side frame 108b is fixed in breaking member 1225b in the side frame portion of door shield side.In this application, the side frame that the side frame 108b in the above-mentioned explanation or the door-plate collision parts that are arranged at the door shield plate 1508 etc. of side frame 108b is called the door shield side.
According to this embodiment, under door-plate 116 closing state,, can limit cigarette and flame and flow into hoistway side through this gap from the stop side even when high temperature, also can block the gap between door-plate 116b and the door shield plate 1508.
(the 2-4. upper frame is used blocking-up portion)
Then, explain in the formation in each gap between blocking-up door-plate 116 and the upper frame 110 under door-plate 116 closing state being used for reference to Figure 16.Be used for shown in Figure 16 as the diagram of explaining along a formation example of the cutaway view of the I-I line of Figure 12, that be used to block the gap between door-plate 116 and the upper frame 110.As previously mentioned; Under the situation of two-fold single opened door; Door-plate 116a, 116b are configured to observe from the boarding direction and are the AM/BAM scalariform, therefore the upper frame 110 of door pocket 104 also become with the corresponding formation this point of the configuration of door-plate on different with the embodiment of the situation of aforementioned double-open type door.In addition, upper frame 110 comprises: among Figure 12 with the interval 110a in the prostatitis in the cooresponding left side of door-plate 116a and with the interval 110b of the rank rear on the cooresponding right side of door-plate 116b.The interval 110a in the prostatitis of upper frame 110 compares with the interval 110b of rank rear, and the length of the switching direction of door is short.But; Except these are put; Upper frame under the situation of two-fold single opened door does not have difference with the upper frame under the situation of blocking-up portion and the double-open type door that in (1-3), is illustrated with reference to Fig. 9 with the desired condition of blocking-up portion, thus can be to the upper frame under the situation of two-fold single opened door with the upper frame under the situation of the employing of blocking-up portion and the double-open type door that in (1-3), is illustrated with reference to Fig. 9 with the identical formation of blocking-up portion.In addition; Except the interval 110a in the prostatitis of upper frame 110 lacks this point with the length that the interval 110b of rank rear compares the switching direction of door; There is not difference in upper frame with being formed between interval, prostatitis and the rank rear interval of blocking-up portion; So, mainly the upper frame in the gap between interval 110a in the prostatitis of blocking-up upper frame 110 and the door-plate 116a is explained with the formation of blocking-up portion.Moreover, in the following record, sometimes the interval 110a in the prostatitis of upper frame 110 is called upper frame 110a; Interval 110b is called upper frame 110b with the rank rear of upper frame 110.
Under door-plate 116 closing state, there is gap between door-plate 116a and the upper frame 110 by reference symbol 1602 expressions.In order to block this gap 1602, the assembling upper frame is with breaking member 1226.Upper frame is formed by stacking by the rubber-like polymer member at least a portion of rubber-like imcombustibility parts and the one side at least that is disposed at the imcombustibility parts with breaking member 1226.
Upper frame is with the breaking member 1226 base end part 1226c through this breaking member 1226, the hoistway side of and upper frame 110 closely fixing with the mode that does not form the gap between breaking member 1226 and the upper frame 110.For example, through sticker metal pressing plate 1604 is adhered to the base end part 1226c of breaking member 1226, being situated between closely is fixedly linked on upper frame 110 by stop screw 1606 with base end part 1226c that is adhered and pressing plate 1604 integratedly.Here, the part of the base end part 1226c of breaking member 1226 is integrally formed, by aforementioned rubber-like imcombustibility component set-up.The upper frame that is arranged at upper frame 110a extends along the almost total length of the left and right directions of upper frame 110a with breaking member 1226 continuously, for example, is situated between by stop screw 1606, and the spacing by appointment closely is fixed in upper frame 110a through base end part 1226c.Moreover the upper frame that is arranged at upper frame 110b extends along the almost total length of the left and right directions of upper frame 110b with breaking member 1226 continuously, for example, is situated between by stop screw 1606, and the spacing by appointment closely is fixed in upper frame 110b through base end part 1226c.
Upper frame is integrally formed with the upside and the base end part 1226c of breaking member 1226, becomes the extension 1226d that extends obliquely to door-plate 116a side direction top from base end part 1226c.Extension 1226d has the effect of spring by the rubber-like imcombustibility component set-up that extends to door-plate 116a side from base end part 1226c.Be built up the part 1226e that is made up of the rubber-like polymer member at extension 1226d, this part 1226e is positioned at least a portion as a relative side with door-plate 116a of the part of this extension 1226d.Shown in figure 16, upper frame is with the extension 1226d maintenance of breaking member 1226 and the posture of the surperficial relative tilt of door-plate 116a, and simultaneously, for example front-end edge portion is crooked to curve circular-arc mode backward.The side of polymer member part 1226e that under the door closing state, is disposed at the front end sidepiece of extension 1226d flexibly and closely contacts with the upper face of door-plate 116a.Through this contact, the gap 1602 between upper frame 110a and the door-plate 116a is by blocking-up airtightly.Equally, being disposed at the upper frame of being located at upper frame 110b flexibly and closely contacts with the upper face of door-plate 116b with the side of the polymer member part 1226e of the front end sidepiece of the extension 1226d of breaking member 1226.Through this contact, the gap 1602 between upper frame 110b and the door-plate 116b is by blocking-up airtightly.
Even presence of fire involves near the stop; Upper frame becomes high temperature with breaking member 1226; Polymer member part 1226e thereby the state of affairs that disappear former because of fusing etc.; Because extension 1226d is by rubber-like imcombustibility component set-up, so same with the extension 1224d of breaking member 1224 with the side frame portion of aforementioned door camera bellows side, the side of the front-end edge portion of each extension 1226d is with the surface elasticity ground of door- plate 116a and 116b and closely contact.Through this contact, even under the situation that polymer member part 1226e disappears, the gap between upper frame 110a and door-plate 116a and upper frame 110b and the door-plate 116b is also by blocking-up airtightly.
Moreover, record and narrate with breaking member 124 fronts about the side frame portion of double-open type door, and can adopt various shape and mode with breaking member 1226 as upper frame, be not limited to shape shown in Figure 16 and mode.For example; Like the side frame portion through Fig. 7 and double-open type door shown in Figure 8 with breaking member 124; Can be at the extension 1226d configuration rubber-like polymer member part 1226e of upper frame with breaking member 1226; Make its except superimposed on the side that contacts with the surface of door-plate 116 under the door closing state, also superimposed on the opposition side of extension 1226d.That is, upper frame is constituted by 1226e clamping of rubber-like polymer member part or encirclement with the extension 1226d of breaking member 1226.
In addition; In embodiment shown in Figure 16, upper frame is with the extension 1226d maintenance of breaking member 1226 and the posture of the surperficial relative tilt of door-plate 116, simultaneously; Front-end edge portion is crooked to curve circular-arc mode backward; The side of polymer member part 1226e that is disposed at the front end sidepiece of extension 1226d flexibly and closely contacts with the upper face of door-plate 116a, and thus, the gap 1602 between upper frame 110 and the door-plate 116 is by blocking-up airtightly.But the gap 1602 of blocking airtightly between upper frame 110 and the door-plate 116 through breaking member is not limited to aforementioned manner.For example; Upper frame is with the extension 1226d maintenance of breaking member 1226 and the posture of the relative straight inclined in surface of door-plate 116; Simultaneously; The side of polymer member part 1226e of side that is disposed at the pars intermedia of extension 1226d flexibly and closely contacts with the upper face of door-plate 116, thus, can block the gap 1602 between upper frame 110 and the door-plate 116 airtightly.
According to the embodiment of above explanation, under door-plate 116 closing state,, can limit cigarette and flame and flow into hoistway side through this gap from the stop side even when high temperature, also can block the gap between upper ledge 110 and each door-plate 116.
In addition, as previously mentioned, for example through sticker pressing plate 1604 is assemblied in the base end part 1226c of upper frame with breaking member 1226 in advance, under this state, base end part 1226c is fixed in upper frame 110 through stop screw 1606.Therefore, through strengthening base end part 1226c with pressing plate 1604, the distortion of base end part 1226c is prevented, and in upper frame 110, upper frame is with being blocked between breaking member 1226 and the upper frame 110 with breaking member 1226 close fit for upper frame.
Moreover, when door- plate 116a, 116b open and close, the top of each door-plate 116 and superimposed at upper frame with the polymer member part 1226e moving contact on the extension 1226d of parts 1226.Therefore, it is desirable to: be used for upper frame with the parts of the polymer member part 1226e of breaking member 1226 having the suitable elastomeric while, also have suitable slyness property and abrasion performance.
Moreover; Open at door-plate 116b, when direction moves to the left; Door-plate 116b separates with breaking member 1226 with the upper frame of being located at upper frame 110b, and direction moves to the right, door is when closing at door-plate 116b, contacts with breaking member 1226 with the upper frame of being located at upper frame 110b once more.At this moment, contact sleekly with breaking member 1226 with the upper frame of being located at upper frame 110b, can assemble guide member (not illustrating) by side edge part on the top of door-plate 116b in order to make door-plate 116b.This guide member form conical suface and be configured to door-plate 116b to the right direction move, the edge portion butt of the extension 1226d of conical suface and breaking member 1226 when door is closed.Like this; Conical suface be located at the edge portion butt of the upper frame of upper frame 110b with the extension 1226d of breaking member 1226; Thus; The extension 1226d of the upper frame of upper frame 110b with breaking member 1226 is located in guiding, and it is contacted with the surface slyness of door-plate 116b, can when door-plate 116b closes, block the gap between door-plate 116b and the upper frame 110b reliably.
(2-5. sill portion uses blocking-up portion)
As previously mentioned; Under the situation of two-fold single opened door; Two door-plate 116a, 116b are configured to be the AM/BAM scalariform from the observation of boarding direction; Therefore, also form on the cooresponding formation this point of configuration with door-plate, with the formation of sill under the situation of aforementioned double-open type door and dispose different at sill 106.Before the embodiment of explanation sill portion, at first the formation and the configuration of 106 parts of the sill under the situation of two-fold single opened door are set forth with breaking member.Observe the birds-eye view of sill 106 shown in Figure 17 from the top.Door-plate 116a and 116b are configured to AM/BAM rock bench staggered positions on sill 106.The bottom of door-plate 116a and 116b is respectively fitted with leads boots 122a and 122b, and it is side-prominent to sill 106 from the bottom of door-plate 116a and 116b respectively to lead boots 122a and 122b.On sill 106, form the guiding groove 1708a that leads boots 122a and the guiding groove 1708b that leads boots 122b that guides door-plate 116b of guiding door-plate 116a along the length direction of sill 106.In addition, the bottom surface of each guiding groove 1708a and 1708b is formed for discharging the discharge orifice 1710 of foreign matters such as rubbish.
Then, explain in the formation in each gap between blocking-up door-plate 116 and the sill 106 under door-plate 116 closing state being used for reference to Figure 18 and Figure 19.Sill portion under the situation of two-fold single opened door can adopt sill portion under the situation with the double-open type door that is illustrated with reference to Figure 10 with the same formation of blocking-up portion with blocking-up portion.
Be used for shown in Figure 18 as the diagram of explaining along a formation example of the cutaway view of the J-J line of Figure 17, that be used to block the gap between door-plate 116a and the sill 106.
Under door-plate 116 closing state, there is gap between door-plate 116a and the sill 106 by reference symbol 1802 expressions.In order to block this gap 1802, be equipped with sill portion at door-plate 116a and use breaking member 1228a.Sill portion is formed by stacking by the rubber-like polymer member at least a portion of rubber-like imcombustibility parts and the one side at least that is disposed at the imcombustibility parts with breaking member 1228a.
The underbeam 1810 of door-plate 116a is fixed in sill portion through the base end part 1228c of this breaking member 1228a with breaking member 1228a.Sill portion is closely fixing with the mode that does not form the gap between this breaking member 1228a and the underbeam 1810 with breaking member 1228a.For example, metal pressing plate 1804 is adhered to the base end part 1228c of breaking member 1228a, base end part 1228c that is adhered and pressing plate 1804 closely is fixedly linked on integratedly the underbeam 1810 of door-plate 116 through stop screw 1806 through sticker.Here, the part of the base end part 1228c of breaking member 1228a is integrally formed, by aforementioned rubber-like imcombustibility component set-up.
Sill portion extends along the almost total length of the left and right directions of the bottom of door-plate 116a with breaking member 1228a continuously, for example, is situated between by stop screw 1806, by the spacing of appointment, closely is fixed in the underbeam 1810 of door-plate 116a through base end part 1228c.
Sill portion is integrally formed with lower side and the base end part 1228c of breaking member 1228a, becomes the extension 1228d that extends to sill 106 sides from base end part 1228c.Extension 1228d has the effect of spring by the rubber-like imcombustibility component set-up that begins to extend from base end part 1228c, and said base end part 1228c is by rubber-like imcombustibility component set-up.Be built up the part 1228e that is made up of the rubber-like polymer member at extension 1228d, this part 1228e is disposed at as the part of this extension 1228d and at least a portion sill 106 relative sides.Shown in figure 18; Sill portion is with the extension 1228d maintenance of breaking member 1228a and the posture of the top relative tilt of sill 106; Simultaneously; For example front-end edge portion is crooked to curve circular-arc mode backward, and the side of polymer member part 1228e of leading section that is disposed at extension 1228d is with the flexibly top of sill 106 and closely contact.Through this contact, the gap 1802 between door-plate 116a and the sill 106 is by blocking-up airtightly.
As previously mentioned, form the discharge orifice 1710 that the discharge foreign matter is used in the bottom surface of the guiding groove 1708a that is located at sill 106 sometimes.But; Shown in figure 18; Sill portion with breaking member 1228a than the position that forms guiding groove 1708 more near a side of stop with contact and block gap 1802 above the sill 106; The discharge orifice 1710 that can limit from the cigarette of stop side and the flame bottom surface through being formed at guiding groove 1708 thus, flows in the hoistways.
Near the fire propagation stop, sill portion becomes high temperature with breaking member 1228a, and polymer member part 1228e also maybe be because of former thereby disappearances such as fusings.Even such state of affairs takes place, because extension 1228d is by rubber-like imcombustibility component set-up, the side of the leading section of extension 1228d is with the flexibly top of sill 106 and closely contact.Through this contact, even under the situation that polymer member part 1228e disappears, the gap 1802 between door-plate 116a and the sill 106 is also by blocking-up airtightly.
Moreover, record and narrate with breaking member 124 fronts about side frame portion, and can adopt various shape and mode with breaking member 1228a as sill portion, be not limited to shape shown in Figure 180 and mode.For example; As through Fig. 7 and side frame portion shown in Figure 8 with breaking member 124; Can be in sill portion with the extension 1228d of breaking member 1228a configuration rubber-like polymer member part 1228e; Make its except superimposed with a side that contacts above the sill 106 on, also superimposed on the opposition side of extension 1228d.That is, sill portion is constituted by 1228e clamping of rubber-like polymer member part or encirclement with the extension 1228d of breaking member 1228.Such formation for example can be through making sill portion with the extension 1228d insertion rubber-like polymer member of breaking member 1228a.
In addition; In embodiment shown in Figure 180, sill portion is with the extension 1228d maintenance of breaking member 1228a and the posture of the top relative tilt of sill 106, simultaneously; Front-end edge portion is crooked to curve circular-arc mode backward; The side of polymer member part 1228e of leading section that is disposed at extension 1228d is with the flexibly top of sill 106 and closely contact, and thus, the gap 1802 between door-plate 116a and the sill 106 is by blocking-up airtightly.But the gap 1802 of blocking airtightly between door-plate 116a and the sill 106 through breaking member is not limited to aforementioned manner.For example; Sill portion is with the extension 1228d maintenance of breaking member 1228a and the posture of the top relative straight inclined of sill 106; Simultaneously; The leading section of polymer member part 1228e of pars intermedia that is disposed at extension 1228d is with the flexibly top of sill 106 and closely contact, and thus, can block the gap 1802 between door-plate 116a and the sill 106 airtightly.
Be used for shown in Figure 19 as the diagram of explaining along a formation example of the cutaway view of the K-K line of Figure 17, that be used to block the gap between door-plate 116b and the sill 106.Be used to block the formation in the gap between door-plate 116b and the sill 106 and block the formation in the gap between door-plate 116a and the sill 106 identical with reference to Figure 18 being used to of being illustrated.
Under door-plate 116 closing state, there is gap between door-plate 116b and the sill 106 by reference symbol 1902 expressions.In order to block this gap 1902, be equipped with sill portion at door-plate 116b and use breaking member 1228b.Sill portion is formed by stacking by the rubber-like polymer member at least a portion of rubber-like imcombustibility parts and the one side at least that is disposed at the imcombustibility parts with breaking member 1228b.
The underbeam 1910 of door-plate 116b is fixed in sill portion through the base end part 1228c of this breaking member 1228b with breaking member 1228b.Sill portion is closely fixing with the mode that does not form the gap between this breaking member 1228b and the underbeam 1910 with breaking member 1228b.For example, metal pressing plate 1904 is adhered to the base end part 1228c of breaking member 1228b, base end part 1228c that is adhered and pressing plate 1904 closely is fixedly linked on integratedly the underbeam 1910 of door-plate 116 through stop screw 1906 through sticker.Here, the part of the base end part 1228c of breaking member 1228b is integrally formed, by aforementioned rubber-like imcombustibility component set-up.
Sill portion extends along the almost total length of the left and right directions of the bottom of door-plate 116b with breaking member 1228b continuously, for example, is situated between by stop screw 1906, by the spacing of appointment, closely is fixed in the underbeam 1910 of door-plate 116b through base end part 1228c.
Sill portion is integrally formed with lower side and the base end part 1228c of breaking member 1228b, becomes the extension 1228d that extends to sill 106 sides from base end part 1228c.Extension 1228d has the effect of spring by the rubber-like imcombustibility component set-up that begins to extend from base end part 1228c, and said base end part 1228c is by rubber-like imcombustibility component set-up.Be built up the part 1228e that is made up of the rubber-like polymer member at extension 1228d, this part 1228e is disposed at as the part of this extension 1228d and at least a portion sill 106 relative sides.Shown in figure 19; Sill portion is with the extension 1228d maintenance of breaking member 1228b and the posture of the top relative tilt of sill 106; Simultaneously; For example front-end edge portion is crooked to curve circular-arc mode backward, and the side of polymer member part 1228e of leading section that is disposed at extension 1228d is with the flexibly top of sill 106 and closely contact.Through this contact, the gap 1902 between door-plate 116b and the sill 106 is by blocking-up airtightly.
As previously mentioned, form the discharge orifice 1710 that the discharge foreign matter is used in the bottom surface of the guiding groove 1708b that is located at sill 106 sometimes.But; Shown in figure 19; Sill portion with breaking member 1228b than the position that forms guiding groove 1708b more near a side of stop with contact and block gap 1902 above the sill 106; The discharge orifice 1710 that can limit from the cigarette of stop side and the flame bottom surface through being formed at guiding groove 1708b thus, flows in the hoistways.
Sill portion is identical with breaking member 1228a with sill portion with the mode of breaking member 1228b, effect, effect etc.
Get back to Figure 17, have the path P of representing by reference symbol P of leading to hoistway side from the stop side between the lower end surface of guiding groove 1708a on be formed at sill 106 and the side edge part of door-plate 116a.In order to block path P, breaking member 1712 is assemblied in the lower end surface of the side edge part of door-plate 116a.Breaking member 1712 for example is built up by rubber-like imcombustibility parts and the rubber-like polymer member of at least a portion of one side at least that is disposed at the imcombustibility parts, and guiding groove 1708a is inserted in the bottom of breaking member 1712.For example; Side edge part among Figure 17 of breaking member 1712 is by the imcombustibility component set-up; The part relative with guiding groove 1708a is that imcombustibility parts and polymer member are formed by stacking on the face of the guiding groove 1708a of these imcombustibility parts side; Through the action of the spring of these parts, the part relative of breaking member 1712 and the top closed contact of guiding groove 1708a with guiding groove 1708a.Like this, can be present in path P between the lower end surface of side edge part of guiding groove 1708a and door-plate 116a, lead to hoistway side from the stop side through breaking member 1712 blocking-up.
Even presence of fire involves near the stop; Breaking member 1712 becomes high temperature; Polymer member part thereby the state of affairs that disappear former because of fusing etc.; Through the action of the spring of rubber-like imcombustibility parts, the part relative of imcombustibility parts and the top closed contact of guiding groove 1708a, blocking-up path P with guiding groove 1708a.
According to the embodiment of above explanation, under door-plate 116 closing state,, can limit cigarette and flame and flow into hoistway side through this gap from the stop side even when high temperature, also can block the bottom of door-plate 116 and each gap between the sill 106.
In addition, as previously mentioned, in advance pressing plate is assemblied in the base end part 1228c of sill portion with breaking member 1228, under this state, base end part 1228c is fixed in the underbeam of door-plate 116 through stop screw.Therefore, through strengthen base end part 1228c with pressing plate, the distortion of base end part 1228c is prevented, and simultaneously, in the underbeam of door-plate 116, sill portion is with being blocked between breaking member 1228 and the door-plate 116 with breaking member 1228 close fit in sill portion.
Moreover; Superimposed in sill portion with the polymer member part 1228e on the extension 1228d of breaking member 1228, and the polymer member part of the superimposed part relative in breaking member 1712 with guiding groove 1708a when door-plate 116 opens and closes and moving contact above the sill 106; Therefore, it is desirable to: use to have the suitable elastomeric material that also has suitable slyness property and abrasion performance simultaneously as these polymer member parts.
(using blocking-up portion for overlapping of the side edge part of 2-6. door-plate)
Under the situation of two-fold single opened door, can know that from Figure 13 under the door closing state, the distolateral side edge part front and back of door-plate 116a and 116b overlap each other.With reference to Figure 20 the example of formation in overlapping gap that is used under door-plate 116 closing state blocking-up and is positioned at the side edge part of two door-plates is explained.Be used for shown in Figure 20 as the diagram of explaining along the formation in overlapping gap of a side edge part example of the cutaway view of the L-L line of Figure 12, that be used to block the side edge part that is positioned at door-plate 116a and door-plate 116b.From Figure 13, can know, overlapping of the side edge part of door-plate with blocking-up portion can adopt with (2-2) in the side frame portion of the door camera bellows side that is illustrated with reference to Figure 14 constitute like the category with blocking.Formation shown in Figure 20 is except the object that polymer member contacted of superimposed extension in breaking member, and is identical with formation essence shown in Figure 14.Under door-plate 116 closing state, for overlapping the gap by reference symbol 2002 expressions of the side edge part of blocking the side edge part that is present in door-plate 116a and side frame 108a and door-plate 116b, overlapping of assembling door is with breaking member 1230.The door overlapping with breaking member 1230 by rubber-like imcombustibility parts be disposed at the imcombustibility parts at least the one side at least a portion on the rubber-like polymer member be formed by stacking.
Overlapping side edge part that is fixed in the door camera bellows side of door-plate 116b with breaking member 1230 through base end part 1230c of door by rubber-like imcombustibility component set-up.Overlapping of door is closely fixing with the mode that does not form the gap between this breaking member 1230 and the door-plate 116b with breaking member 1230.For example, metal pressing plate 2004 is adhered to the base end part 1230c of breaking member 1230, base end part 1230c that is adhered and pressing plate 2004 closely is fixedly linked on integratedly the side edge part of door-plate 116b through stop screw 2006 through sticker.Overlapping of door extends along the almost total length of the above-below direction of door-plate 116b with breaking member 1230 continuously, for example, is situated between by stop screw 2006, and the spacing by appointment closely is fixed in door-plate 116b through base end part 1230c.
An overlapping lateral margin side and base end part 1230c with breaking member 1230 of door is integrally formed, and becomes the extension 1230d that extends to the side edge part side of door-plate 116a from base end part 1230c.Extension 1230d has the effect of spring by the rubber-like imcombustibility component set-up that begins to extend from base end part 1230c, and said base end part 1230c is by rubber-like imcombustibility component set-up.Be built up the part 1230e that is made up of the rubber-like polymer member at extension 1230d, this part 1230e is disposed at least a portion as a relative side with side frame 108a of the part of this extension 1230d.Shown in figure 20; Overlapping of door keeps the posture with the surperficial relative tilt of the side edge part of door-plate 116a with the extension 1230d of breaking member 1230; Simultaneously; For example crooked to curve circular-arc mode backward, the side of polymer member part 1230e that under the door closing state, is disposed at the pars intermedia of extension 1230d flexibly and closely contacts with the side edge part of door-plate 116a.Through this contact, overlapping the gap 2002 of the side edge part of the side edge part of door-plate 116a and door-plate 116b is by blocking-up airtightly.
Near the fire propagation stop, overlapping of door becomes high temperature with breaking member 1230, and polymer member part 1230e is also maybe be because of fusing etc. former thereby disappear.Even such state of affairs takes place, identical with the explanation of carrying out with reference to Fig. 3 (b), because extension 1230d is by rubber-like imcombustibility component set-up, so the side of the pars intermedia of extension 1230d flexibly and closely contacts with the side edge part of door-plate 116a.Through this contact, even under the situation that polymer member part 1230e disappears, overlapping gap 2002 of the side edge part of the side edge part of door-plate 116a and door-plate 116b is also by blocking-up airtightly.
Embodiment according to above explanation; Under door-plate 116 closing state; Even when high temperature, also can block overlapping gap of the side edge part of the side edge part that is positioned at door-plate 116a and door-plate 116b, can limit cigarette and flame and flow into hoistway side through this gap from the stop side.
In addition, through sticker pressing plate 2004 is assemblied in overlapping base end part 1230c with breaking member 1230 of door in advance, under this state, base end part 1230c is fixed in the side edge part of door-plate 116b through stop screw 2006.Therefore, through strengthening base end part 1230c with pressing plate 2004, the distortion of base end part 1230c is prevented, the door overlapping with breaking member 1230 close fit in the side edge part of door-plate 116b, the door overlapping with being blocked between breaking member 1230 and the door-plate 116b.
In addition, can adopt side frame portion under the situation with the double-open type door that is illustrated with reference to Fig. 7 with the identical formation of blocking-up portion.That is, with polymer member partly be configured to except superimposed as overlapping of door with the part of the extension of breaking member 1230, on the side that contacts with the side edge part of door-plate 116a under the door closure state, also superimposed on the opposition side of extension.In such formation, overlapping part with the extension 1230d of breaking member 1230 of door is by part clamping of rubber-like polymer member or encirclement.Such formation for example can be made through overlapping extension 1230d with breaking member 1230 of door inserted the rubber-like polymer member.
Moreover, when door is opened door-plate 116a and door-plate 116b one in the same way a door camera bellows direction move.Therefore at this moment, door-plate 116b compares high-speed mobile with door-plate 116a, under the door closing state, leaves with the extension of breaking member 1230 and the polymer member part side edge portions with door-plate 116a with overlapping of the door of the side edge part closed contact of door-plate 116a.When door was closed, door-plate 116a and door-plate 116b one door shield direction in the same way moved, and overlapping of door contacts through the side edge part with door-plate 116a with the extension of breaking member 1230 and polymer member part and bending arranged slightly.That is, when door was closed, overlapping extension and polymer member with breaking member 1230 of door partly received the stress from the side edge part of door-plate 116a.Therefore, it is desirable to: with overlapping of door with the polymer member part of the extension collapsed configuration of breaking member 1230 having the suitable elastomeric while, have suitable abrasion performance and nerve.
