Fig. 6 (b) is the summary sectional view from the upside observation along the cross section of the I-I ' of Fig. 6 (a).The expression lift-cabin door board 102 corresponding with stop door-plate 302 simultaneously in Fig. 6 (b).
Then, the action to the elevator door apparatus that illustrated in the above-described embodiment describes.At first, with reference to Fig. 7 the action of the lockout mechanism of embodiment shown in Figure 6 is described.Fig. 7 (a) is the figure that the lockout mechanism 306 shown in Fig. 6 (a) is amplified, for the parts of car door, and except the car reveal engagement section 110 that comprises the first engaging sword 216 and the second engaging sword 218 etc., all not expressions in Fig. 7.
When car in hoistway along above-below direction move and stop to the regulation the stop layer time, as mentioned above, first roller 414 of the lockout mechanism 306 of formation car reveal engagement section 110 and second roller 418 are between the first engaging sword 216 and the second engaging sword 218 of car reveal engagement section 110.Under this state, shown in Fig. 7 (a), the hook portion 404 of hook parts is hooked on by in the recess of hook parts 406, hook parts 402 and by hook parts 406 be in hook state.In addition, under this state, the gap width that the lift-cabin door board 102 between the first engaging sword 216 and the second engaging sword 218 opens and closes direction is A0.
Then, illustrated like that as using Fig. 1 when car is being stopped layer and stopped, lift- cabin door board 102 and 104 is via car door band 106, oppositely links by the power that is arranged on the car door motor 108 on the car and opens.On lift-cabin door board 102, the switching campaign of lift-cabin door board 102 is delivered to via car reveal engagement section 110 and is arranged on the stop door of stopping layer.As reference Fig. 2 is illustrated, when lift-cabin door board 102 from buttoned-up status a little when opening direction and move, the first engaging sword 216 is lifted, the second engaging sword 218 is depressed.
Under this state, shown in Fig. 7 (b), the first engaging sword 216 and the gap turn narrow of second engaging between the sword 218 are to A1 (A1＜A0).When gap turn narrow between the sword 218 of the first engaging sword 216 and second engaging, second roller 418 is pushed to figure right-hand (door case direction) by the side plate 219 of the second engaging sword 218, and hook parts 402 are swing upward centered by the axle of first roller 414.As a result, hook portion 404 and be disengaged by the hook state between the hook parts 406.That is, Fig. 7 (b) expression is based on hook parts 402 and the state that is disengaged by locking of hook parts 406.In addition, the gap A1 between first when car door is opened engaging sword 216 and the second engaging sword 218, for example be designed to the diameter of first roller 414 and second roller 418 about equally.
Under this state, as shown in Figures 2 and 3, engaging sword roller 232, and contacts with the end 230a of engaging sword roller guide parts 230 on the upper board 220 that flexibly is supported in car door via load buffer gear 234 in that to open and close direction mobile with the first engaging sword 216.Engaging sword roller 232 is directed with the end 230a butt that engages sword roller guide parts 230 of tilted configuration, and the result makes first position displacement that engages the lifting direction of sword 216 via engaging sword roller 232.Under the state shown in Fig. 7 (b), to compare with the state shown in Fig. 7 (a), engaging sword roller 232 (not shown) and the first engaging sword 216 are to the top displacement of lifting direction.When the excessive load that applies via engaging sword roller 232 pairs of this engaging sword roller guide parts 230 from the first engaging sword 216, bear this load and the coil spring 234b of load buffer gear 234 is compressed, engage 230 declines of sword roller guide parts.Be accompanied by the decline of these engaging sword roller guide parts 230, engaging sword roller 232 descends.As a result, be accompanied by the displacement of the lifting direction of engaging sword roller 232, the first engaging sword 216 is opening and closing the direction top offset, and the load that engaging sword roller guide parts 230 are applied is absorbed.And the interval between the first engaging sword 216 and the second engaging sword 218 is extended, and the load that the first engaging sword 216 is applied is eliminated.
As mentioned above, the gap A1 between first when car door is opened engaging sword 216 and the second engaging sword 218 for example be designed to the diameter of first roller 414 and second roller 418 about equally, and be designed to can not become this below value.But, when the assembling operation of elevator, also might being assembled into mistakenly, it is littler than the diameter of first roller 414 or second roller 418 that this gap A1 becomes.In this case, can be to connecting part 212a, the 212b of linkage part, the moment that effect such as 214a, the employed bearing of 214b is excessive, so clamping close device can not normally move the on-off action generation obstacle of opposite house.In order to reduce the generation of this state of affairs at least, and load buffer gear 234 is provided with at the flexible elastic body of hoistway direction, the displacement of the lifting direction by engaging sword roller guide parts 230 (not shown) can exceedingly not diminish the gap between the face 218a of side plate 219 of the face 216a of side plate 217 of the first engaging sword 216 and the second engaging sword 218.
Fig. 8 represents to engage the displacement and an example that engages the relation between sword 216,218 the gap of the lifting direction of sword roller 232 qualitatively.Under the complete closing state of car door, engaging sword 216,218 gap width are A0, but when car door began to open, engaging sword 216,218 gap width diminished point-blank, engaged sword 216 usually, 218 gap width finally can be reduced to A1 like that shown in straight line 702.But, under the situation that clamping close device is assembled mistakenly, when the displacement of the lifting direction that engages sword roller 232 becomes P2, engaging sword 216,218 is applied the power that hinders engaging sword 216,218 gap smaller, and this power is delivered to load buffer gear 234 from engaging sword roller 232 via engaging sword roller guide parts 230.
When this power was applied on the load buffer gear 234, the elastic body that load buffer gear 234 possesses was further compressed in the lifting direction.The result, shown in 704 among the figure, the power that applies via 232 pairs of engagings of engaging sword roller sword roller guide parts 230 is absorbed by load buffer gear 234, engaging sword roller guide parts 230 become the state that engaging sword 216,218 gap are changed at lifting direction top offset, engaging sword 216,218 gap width probably rest on A2.In other words, at engaging sword 216, when 218 gap diminishes gradually, when to the excessive power of engaging sword 216,218 effects, this power is absorbed by the elastic body of load buffer gear 234 influence of engaging sword 216,218 gap width.
