The specific embodiment
At first, referring to figs. 1 through Fig. 7 the entrance/exit device for elevator in the first embodiment of the present invention is described.Fig. 1 and Fig. 2 all are the section-drawings that are illustrated in threshold 6 that is positioned at the specified part position on the frontal width direction (frontage direction) and the position relation that engages body 3.Wherein, when Fig. 1 is illustrated in the gangway and is in closed condition etc., the situation when above the threshold that is positioned at the specified part position 6, having elevator door 1.On the other hand, when Fig. 2 is illustrated in the gangway and is in open mode etc., the situation when above the threshold that is positioned at the specified part position 6, not having elevator door 1.
As shown in Figure 1, the doorway device of present embodiment has: be arranged on companion way ground and lift car ground etc. ground 8 the end threshold 6, to be formed on the recess to the top opening on this threshold 6 be threshold groove 7, the elevator door 1 that is arranged on the engaging body 3 of the inaccessible mechanism of conduct in this threshold groove 7, the part of this engaging body 3 is supported and moves to the frontal width direction.
At this, be provided with the elevator gate slot in the bottom surface of elevator door 1, be formed with opposed engaging with protuberance 2 at the medial surface of this elevator gate slot.On the other hand, the sidepiece of engaging body 3 be formed with elevator door 1 engage with protuberance 2 fastenings and by the engaging of its guiding with recess 4.In addition, be provided with dust in the bottom of engaging body 3 and discharge, planarization mechanism is installed in the upper surface part that engages body 3 with groove 5.
And, can be not the engaging of elevator gate slot be set to the other end with protuberance 2 from an end of the frontal width direction of elevator door 1 continuously, and can be as shown in Figure 3, only on the position of the part of elevator door 1, engaging is set with protuberance 2.In addition; Through making this engaging form the curved surface shape or adopt additive method with the upside at the two ends of protuberance 2; Make engaging body 3 engage with elevator door smoothly, thus, can reduce the vibration that produced when elevator door contacts with recess 4 with the engaging that engages body 3 and noise etc.
And as shown in Figure 4, the engaging body 3 of present embodiment is linked by a plurality of engaging parts 11, forms the structure of snake shape.And, as shown in Figure 6, do not need to link engaging body 3 single-pieces that form and be sized to size that threshold groove 7 is all covered, but need make its length at least more than the width of gangway.In addition, when adopting the doorway device of the midsplit type that two fan doors are arranged as shown in Figure 6, in order not make engaging body 3 by elevator door 1 pulling and to the skew of frontal width direction, preferably on the position A of the shutdown side of elevator door 1 fixedly threshold 6 with engage body 3.In addition; In the present embodiment; As shown in Figure 5, constitute engaging body 3 through using pin 9 that a plurality of engaging parts 11 are linked together, as the material of engaging body 3; If use poly tetrafluoroethylene (registered trade mark (RTM)) etc. for example in light weight and when having the little High molecular material of self-lubricity and friction coefficient, also can constitute the structure of one.
Below, the action of the doorway device of present embodiment is described.At first, when being in open mode,, be accommodated in threshold groove 7 fully so be positioned at the engaging body 3 of this assigned position owing to above the threshold 6 of the assigned position that is positioned at the gangway width, do not have elevator door 1 in the gangway.At this moment, be positioned at the height identical owing to comprise planarization mechanism at the upper surface of interior engaging body 3, so can stop up the threshold groove 7 that exposes when elevator door 1 is opened with the ground of gangway 8.Consequently, can suppress entering because of foreign matter makes elevator door 1 that motor defect take place and is firmly caused that the passenger falls down by hook etc. because of umbrella or high-heeled shoes etc.
And, as shown in Figure 5 when elevator door 1 moves and when making the gangway form closed condition, along with the engaging of elevator door 1 is approaching with protuberance 2, lifted gradually near the engaging parts 11 of this engaging with protuberance 2 one sides.After this, during with protuberance 2, form state shown in Figure 1 with the engaging of recess 4 arrival elevator doors 1 when the engaging of engaging parts 11.At this moment, be positioned at least a portion of upper surface of engaging body 3 that the top has the position of elevator door 1 and be positioned at the position higher than the ground of gangway 8.Thus, even the passenger is poured on the elevator door 1 or elevator door is pushed, can prevent that also elevator door 1 from coming off.
As stated, the engaging body 3 in the present embodiment has played the function of when elevator door 1 is opened, stopping up threshold groove 7 and the function that comes off that prevents elevator door 1 simultaneously.And, when setting should engage body 3, owing to this engaging body 3 can not bloat towards the side direction of threshold 6, so needn't enlarge the gap between elevator lobby side door sill and the lift car side door sill.In addition; Can be with up and down above-mentioned engaging body 3 is arranged on any one of threshold groove 7 of threshold groove 7 and lift car side of elevator lobby side along with passing through of elevator door 1; And as shown in Figure 7, can certainly on two thresholds, all be provided with, these two kinds of methods to set up are all effective.
Fig. 8 and Fig. 9 are the constructionals drawing of the entrance/exit device for elevator in the expression second embodiment of the present invention.Like these Fig. 8 and shown in Figure 9, in the present embodiment, be with the difference of first embodiment, be provided with engaging roller 12 at the medial surface of elevator gate slot.Be specifically, the engaging among first embodiment has been adopted the mode of orienting lug with protuberance 2, and the engaging roller 12 in the present embodiment has then adopted the mode of guiding roller.
In addition, the engaging body 3 of present embodiment is also the same with first embodiment, stops up threshold groove 7 so that when foreign matter is difficult to get into, and is directed into its top and follows moving of elevator door 1 and engage with elevator door 1.And, the same with first embodiment, because elevator lobby ground 8a increases to the flat condition between the 8b of lift car ground, so the safety can improve elevator about the passenger time.
In addition, in first embodiment, the doorway device of the midsplit type of two fan doors is arranged is that example is illustrated with shown in Figure 6, but also can be used for the doorway device of the single opened that two fan doors are arranged shown in Figure 10.At this moment and since the shutdown side B of elevator door 1 fixedly threshold 6 with engage body 3, so can prevent to engage the skew of body 3 to the frontal width direction.
In addition; In above-mentioned first embodiment and second embodiment, be arranged on recess 4 on the engaging body 3 will engaging, and in the elevator gate slot, be provided with engaging with protuberance 2; Use protuberance but also can be employed in to be provided with to engage on the engaging body 3, and the structure of engaging with recess is set in the elevator gate slot.
