Have, above-mentioned raised line 6c is shaped with the above-mentioned airtight member 6 of rubber molding the time simultaneously again.
By said structure, the same with the situation of above-mentioned embodiment of the present invention 1, the bottom airtight member 6 by reducing the stop door and the area of contact of stop sill 4 prevent the increase of adhering to the running resistance that is caused of airtight member 6 and sill 4.When in addition, having prevented the switching of door 1 because the abnormal sound that the stick-slip of airtight member 6 etc. are produced.Have again, even the raised line 6c that is provided with on the airtight member 6 of bottom not necessarily extends abreast with respect to the direction vertical with the switching direction of door 1, even, also can obtain same effect along extending with the direction of the angular cross of a certain degree with the switching direction of door 1.
This structure can similarly be used for being provided with in the bottom of car door the situation of bottom airtight member, also has same effect in this case.
According to Fig. 7 and Fig. 8 embodiments of the present invention 3 are described below.Fig. 7 is the longitudinal diagram of main portion, and Fig. 8 is the amplification stereogram of the airtight member among Fig. 7.
The structure of embodiment of the present invention 3 is, as above-mentioned low friction part 6b, is dispersed with protruding 6d on the crimping face 6a of above-mentioned airtight member 6 and face 4b above-mentioned ground side crimping.
Have, above-mentioned protruding 6d is shaped with the above-mentioned airtight member 6 of rubber molding the time simultaneously again, or waits by coating and to be shaped.
By said structure, the same with the situation of above-mentioned embodiment of the present invention 1, the bottom airtight member 6 by reducing the stop door and the area of contact of stop sill 4 prevent the increase of adhering to the running resistance that is caused of airtight member 6 and sill 4.When in addition, having prevented the switching of door 1 because the abnormal sound that the stick-slip of airtight member 6 etc. are produced.
According to Fig. 9 and Figure 10 embodiments of the present invention 4 are described below.Fig. 9 is the longitudinal diagram of main portion, and Figure 10 is the amplification stereogram of the airtight member among Fig. 9.
In the embodiments of the present invention 4, the flexible airtight member 6 of on the switching direction A of door main body 1b, extending, be installed on the above-mentioned door main body 1b with state flexible by means of it and that be crimped on the face 4b of ground side, above-mentioned airtight member 6 is under the state that is crimped on the face 4b of above-mentioned ground side, switching along with above-mentioned door 1, and on the face 4b of above-mentioned ground side, slide, in the door gear of such elevator, make pressure contact portion 6e flexible of above-mentioned airtight member 6 and face 4b above-mentioned ground side crimping, than from flexible little to the part 6g of the installation portion 6f on above-mentioned door main body 1b of the pressure contact portion 6e of the face 4b crimping of above-mentioned ground side.
Flexible for the pressure contact portion 6e that makes above-mentioned airtight member 6 and face 4b above-mentioned ground side crimping, than from flexible little to the airtight portion 6g midway of the installation portion 6f on above-mentioned door main body 1b of the pressure contact portion 6e of the face 4b crimping of above-mentioned ground side, in embodiments of the present invention 4, make the thickness T of the pressure contact portion 6e of above-mentioned airtight member 6 and face 4b above-mentioned ground side crimping, than from big to the thickness t of the middle airtight portion 6g midway of the installation portion 6f on above-mentioned door main body 1b with the pressure contact portion 6e of the face 4b crimping of above-mentioned ground side.
In switching by stop door 1, when bottom airtight member 6 is slided on stop sill upper surface 4b, 6 vibrations of bottom airtight member.Therefore, suppress vibration by the leading section 6e that makes airtight member 6 greatly than middle airtight portion 6g thickness.When like this, having prevented that door from opening and closing because the abnormal sound that stick-slip etc. are produced.
This structure also can similarly be used for being provided with in the bottom of car door the situation of bottom airtight member, also has same effect in this case.
Embodiment 5
According to Figure 11 and Figure 12 embodiments of the present invention 5 are described below.Figure 11 is the longitudinal diagram of main portion, and Figure 12 is the amplification stereogram of the airtight member among Figure 11.
Flexible for the pressure contact portion 6e that makes above-mentioned airtight member 6 and face 4b above-mentioned ground side crimping, than from flexible little to the part 6g of the installation portion 6f on above-mentioned door main body 1b of the pressure contact portion 6e of the face 4b crimping of above-mentioned ground side, in embodiments of the present invention 5, above-mentioned airtight member 6 from the pressure contact portion 6e of the face 4b crimping of above-mentioned ground side part to the installation portion 6f on above-mentioned door main body 1b, be provided with the upwardly extending folding line 6h of portion in switching side at above-mentioned door.
When the switching of stop door 1, according to the state of stop door 1 and sill 4, the following End play of stop door 1 and sill 4 changes.If above-mentioned airtight member 6 from solid to the part 6g of the installation portion 6f on above-mentioned door main body 1b with the pressure contact portion 6e of the face 4b crimping of above-mentioned ground side, when opening and closing under the situation that the End play diminishes at present, bottom airtight member 6 is by compression failure, the resistance of bottom airtight member 6 and sill 4 is excessive, and possible generator gate opens and closes bad/abnormal sound.Therefore, by the part at the handle of this airtight member the 6h of folding line portion is set, even at the pressing force that reduces the bottom airtight member, under the situation of lower end gap smaller, it is big that resistance can not become yet.
This structure also can similarly be used for being provided with in the bottom of car door the situation of bottom airtight member, also has same effect in this case.
