[0010] In Fig. 1 and Fig. 4, at the elevator landing, between the landing door 1 and the three-way frame vertical frame 2, between the landing door 1 and the three-way frame upper frame 3, and between the landing door 1 and the landing threshold 4 There are gaps in the area, so it is said to have low flame and smoke barrier properties. Therefore, in order to improve smoke shielding and flame shielding properties, an airtight material is arranged in each gap of the landing door. In the landing door seen from the hoistway side force in Fig. 2, an airtight material 6 is added to the lower end of the door, where the door leg 7 is not provided.

[0011] The airtight member 6 fixed to the lower part of the landing door 1 and in close contact with the sill 4 is installed in front of the landing side of the groove 4a of the landing sill 4, and is an extension of the panel la surface of the landing door 1. Therefore, when the landing door 1 is closed, it effectively prevents the leakage of smoke through the landing door 1.

[0012] A flexible airtight member 6 extending in the opening / closing direction A of the door main body lb is attached to the door main body lb in a state of being pressed against the floor-side surface 4b by the flexibility. The airtight material 6 slides on the floor-side surface 4b in contact with the floor-side surface 4b as it opens and closes.

[0013] A low friction portion 6b is formed on a pressure contact surface 6a of the airtight material 6 with the floor-side surface 4b. The low friction portion 6b is formed by providing a groove 6bl or a ridge 6b2 extending in the door opening / closing direction A on the pressure contact surface 6a of the airtight material 6 with the floor-side surface 4b. .

[0014] The groove 6bl or the protrusion 6b2 is formed at the same time as the airtight member 6 is formed of rubber.

[0015] It should be noted that instead of the groove 6bl provided in the lower airtight material 6 in the door opening and closing direction A It may be extended ridges.

[0016] In the first embodiment of the present invention described above, by increasing the contact area between the lower airtight material 6 of the landing door and the landing sill 4, the running resistance is increased due to the adhesion between the airtight material 6 and the sill 4. prevent. In addition, when the door 1 is opened / closed, abnormal noise due to stake or slip of the airtight material 6 is prevented. Furthermore, the groove 6blZ ridge 6b2 provided in the lower airtight member 6 does not necessarily extend parallel to the opening / closing direction of the door 1, but extends at an angle with respect to the opening / closing direction of the door 1. However, the same effect can be obtained.

[0017] This structure can be used in the same manner even when a lower airtight material is provided at the lower part of the force door, and in this case, the same effect is obtained.

[0018] Embodiment 2.

The second embodiment of the present invention will be described below with reference to FIGS. FIG. 5 is a longitudinal sectional view of the main part, and FIG. 6 is an enlarged perspective view of the hermetic material in FIG.

In Embodiment 2 of the present invention, as the low friction portion 6b, a pressure contact surface 6a of the airtight material 6 with the floor-side surface 4b is perpendicular to the opening / closing direction A of the door 1, that is, A plurality of protrusions 6c extending in the crossing direction are provided at predetermined intervals in the opening / closing direction A of the door 1.

[0020] The protrusion 6c is formed at the same time as the airtight member 6 is formed of rubber.

[0021] With this configuration, the airtight material 6 is reduced by reducing the contact area between the lower airtight material 6 of the landing door and the landing sill 4 as in the first embodiment of the present invention described above. This prevents an increase in running resistance due to the sticking to the threshold 4. In addition, when the door 1 is opened and closed, an abnormal noise due to a stake or slip of the airtight material 6 is prevented. Furthermore, the protrusion 6c provided on the lower airtight member 6 does not necessarily extend parallel to the opening / closing direction of the door 1, but crosses it at a certain angle with the opening / closing direction of the door 1. Even if it extends, the same effect is acquired.

[0022] This structure can be used in the same manner even when a lower airtight material is provided at the lower part of the force door, and in this case, the same effect can be obtained.

[0023] Embodiment 3.

The third embodiment of the present invention will be described below with reference to FIGS. 7 is a longitudinal sectional view of the main part, and FIG. 8 is an enlarged perspective view of the airtight material in FIG.

In Embodiment 3 of the present invention, the floor side of the airtight material 6 is used as the low friction portion 6b. The projection 6d is scattered on the pressure contact surface 6a with the surface 4b.

[0025] The protrusion 6d is formed at the same time as the airtight member 6 is formed of rubber, or is formed by coating or the like.

[0026] By configuring in this way, the airtight material 6 is reduced by reducing the contact area between the lower airtight material 6 of the landing door and the landing sill 4 as in the case of the first embodiment of the present invention described above. This prevents an increase in running resistance due to the sticking to the threshold 4. In addition, when the door 1 is opened and closed, an abnormal noise due to a stake or slip of the airtight material 6 is prevented.

[0027] Embodiment 4.

A fourth embodiment of the present invention will be described below with reference to FIGS. 9 and 10. 9 is a longitudinal sectional view of the main part, and FIG. 10 is an enlarged perspective view of the airtight material in FIG.

[0028] Embodiment 4 of the present invention is such that the flexible airtight member 6 extending in the opening / closing direction A of the door main body lb is pressed against the floor-side surface 4b by the flexibility. In an elevator door device that is attached to lb and slides on the floor-side surface 4b in a state where the air-tight material 6 is pressed against the floor-side surface 4b as the door 1 is opened and closed, The pressure contact portion 6e force of the material 6 with the floor side surface 4b The pressure contact portion 6e with the floor side surface 4b is less flexible than the portion 6g reaching the attachment portion 6f to the door body lb. It is.

[0029] The pressure contact portion 6e with the floor side surface 4b from the airtight portion 6g in the middle from the pressure contact portion 6e with the floor side surface 4b of the airtight material 6 to the mounting portion 6f to the door body lb. In the fourth embodiment of the present invention, the intermediate portion of the airtight member 6 that is in pressure contact with the floor-side surface 4b is also in the middle of reaching the attachment portion 6f to the door body lb. The thickness T of the pressure contact portion with the floor surface is made larger than the thickness t of the portion 6g.

[0030] When the landing door 1 is opened and closed, when the lower airtight member 6 slides on the upper surface 4b of the landing sill, the lower airtight material 6 vibrates. Therefore, vibration is suppressed by making the thickness 6 of the airtight member 6 greater than the thickness 6g of the intermediate airtight portion 6e. This prevents abnormal noise caused by stakes and slips when the door is opened and closed.

[0031] This structure can be used in the same manner even when a lower airtight material is provided at the lower part of the force door, and in this case, the same effect is obtained.

[0032] Embodiment 5. Embodiment 5 of the present invention will be described below with reference to FIGS. 11 and 12. FIG. 11 is a longitudinal sectional view of the main part, and FIG. 112 is an enlarged perspective view of the hermetic material in FIG.

[0033] The pressure-contact portion 6e with the floor-side surface 4b is more flexible than the portion 6g from the pressure-contact portion 6e with the floor-side surface 4b of the airtight member 6 to the attachment portion 6f to the door body lb. In order to reduce the performance, in Embodiment 5 of the present invention, a pressure contact portion 6e force of the airtight material 6 with the floor-side surface 4b is provided at a portion reaching the attachment portion 6f to the door body lb. It has a fold 6h that extends in the opening and closing direction.

[0034] When the landing door 1 is opened and closed, depending on the state of the landing door 1 and the sill 4, the lower end gap between the landing door 1 and the sill 4 varies. If the portion 6g from the pressure contact portion 6e to the floor surface 4b of the airtight material 6 to the attachment portion 6f to the door body lb is sturdy, the lower airtightness is reduced when the lower end gap becomes small during opening and closing. The material 6 is crushed, the resistance between the lower airtight material 6 and the sill 4 becomes too large, and there is a risk of door opening / closing failure / noise. For this reason, by providing a crease 6h in the handle portion of the airtight material, the pressing force of the lower airtight material is reduced so that the resistance does not increase even when the lower end gap is reduced.

[0035] This structure can be used in the same manner even when a lower airtight material is provided at the lower part of the force door, and in this case, the same effect is obtained.
