Description

  The present invention relates to the structure of an elevator smoke shielding device, and in particular, is a technique suitable for reducing the installation and adjustment time because the parts price is low.

  Generally, an elevator door constitutes a three-way frame including a door, an upper frame surrounding the door, and a vertical frame. A gap for the door to travel is formed between the door and the frame or the sill. That is, a gap is provided between the door and the upper frame, between the door and the vertical frame, and between the door and the sill. As described above, the gap between the door and the upper frame, the vertical frame, or the sill is necessary for the door to open and close without a feeling of friction and to absorb errors during installation.

On the other hand, when a building fire or the like occurs, there is a problem in terms of disaster prevention where smoke enters the hoistway through the gap between the elevators and causes the hoistway to become a chimney.
For this reason, conventionally, various techniques have been proposed to eliminate this gap in the elevator. For example, a holding member that can be displaced in the vertical direction at the lower end of the door body, and the door between the lower end of the door body and the floor by contacting the floor of the doorway when the door is closed by the holding member. A seal member made of an elastic body that shields the gap, a position adjustment member attached to the holding member, and a positioning surface for positioning the seal member by contacting the position adjustment member are placed on the floor during positioning. A configuration has been proposed in which a positioning spacer is provided. (For example, refer to Patent Document 1).

JP 2005-15086 A

However, the conventional structure described above requires a spacer, which increases the number of parts and causes extra time during installation.
Further, in the conventional configuration, since the holding member and the seal member are integrated, there is a problem that it is not possible to replace only the seal member for filling the gap.
Furthermore, in the prior art, since the door is configured to come into contact with the floor or the floor where the door leg is fixed, the seal member must be displaced in order to increase the contact area with the seal member. In other words, this displacement causes a problem that the seal member is significantly deteriorated.

  The present invention has been made to solve the above-described problems, and can shorten the time for door installation and adjustment, and prevent the elastic member from being damaged or deteriorated. An object of the present invention is to provide an elevator door that can be used.

  An elevator door according to one aspect of the present invention is provided with a door main body that opens and closes an elevator entrance, a position adjustment member that is provided at a lower end portion of the door main body and that can be displaced in the vertical direction, and is attached to the position adjustment member. An elastic member made of an elastic body that is attached to the guide member and that is attached to the guide member and shields a gap between the lower end portion of the door main body and the sill portion of the door when the door is closed, When installing the door body, the position adjustment member is used to displace the guide member and the elastic member upward so that the elastic body is housed in the door body, and the door body is completely installed. Then, the elastic member is positioned by displacing the holding member and the elastic member downward by the position adjusting member.

  The elastic member may be attached by being slid and inserted into the guide member.

A groove for moving the elastic member in close contact may be formed in the sill, and the elastic member may move in close contact with the inner surface of the groove.
The sill may be provided with an inclined surface for moving the elastic member in close contact, and the elastic member may be moved in close contact with the inclined surface.

According to the present invention, the elastic member is temporarily retracted into the lower end portion of the door when the door is installed, and when the door is installed, the position adjustment member is moved downward to arrange the elastic member. As a result, it is possible to prevent the elastic member from being damaged and the airtightness from being lost when the door is installed. Moreover, the trouble of adjusting the position of the elastic member at the time of door installation can be reduced.
Also, when replacing the elastic material, after retracting the elastic material by the position adjustment member, slide the elastic material and pull it out from the opening end, and then slide the new elastic material from the opening end again and attach, It can be easily replaced without replacing or removing the entire door.
Further, by forming a groove for moving the elastic material in the sill portion, the elastic material comes into contact with the inner surface of the groove, so that the contact area is increased and airtightness can be maintained.
Moreover, an inclined surface is formed in a sill part, and an elastic member contact | abuts to this inclined surface, A contact area can be enlarged and airtightness can be maintained.

Embodiments according to the present invention will be described below with reference to the drawings.
First, the basic overall structure of the door portion of the elevator doorway will be described.
As shown in FIG. 1, the elevator doorway apparatus includes a door 1, an upper frame 2 and a vertical frame 3 that surround the door 1, and a sill 4 on which the door 1 travels.

The door 1 is a one-sided door composed of a high speed door 1a and a low speed door 1b. As shown in FIGS. 1 and 2, the high-speed door 1a is located far from the door pocket 5 and moves faster than the low-speed door 1b when performing an opening / closing operation.
When the door 1 is fully closed, the high-speed door 1a and the low-speed door 1b are closed on the left and right sides as shown in FIG. 2A, and when the door 1 is fully opened, the high-speed door 1a and the low-speed door 1b are closed as shown in FIG. As shown in the figure, the high-speed door 1a and the low-speed door 1b are folded and overlapped and stored in the door pocket 5 to be fully opened.

Further, as shown in FIG. 3, the upper frame 2 has a high-speed door 1a and a low-speed door 1b suspended from each other by a door hanger 6 connected to a driving device.
The vertical frame 3 is composed of a vertical frame 3a (left side in the figure) on which the high-speed door 1a hits when fully closed and a vertical frame 3b (right side in the figure) on the door pocket 5 side. The vertical frame 3a constitutes a door holding portion when the high speed door 1a is closed.

  The sill 4 is formed with a guide groove for traveling with a guide shoe provided at the lower ends of the high-speed door 1a and the low-speed door 1b, so that the door 1 moves left and right along the guide groove. It is configured.

One embodiment of the smoke shielding structure according to the present invention is shown in FIGS.
FIG. 5 shows a structure in which a gap between the vertical frame 3a and the vertical frame 3a constituting the door holding portion to which the high speed door 1a hits when the fully closed state is blocked.
As shown in FIG. 5, a guide 10 and a rubber material 12 attached to the guide 10 are attached to the back side (the hoistway side) of the vertical frame 3 a.

The guide 10 is formed in a flat plate shape extending in the vertical direction along the vertical frame 3a, and is attached to the lower end of the vertical frame 3a with screws 11 from the upper end. A guide groove 10a is formed in a straight line in the longitudinal direction of the side end of the guide 10 on the door 3 side. The guide groove 10a is formed with a fold extending inward at an opening thereof, and the rubber material 12 fitted into the guide groove 10a is engaged and attached by the fold. The upper and lower ends of the guide groove 10 are open.
The guide 10 can be manufactured by extrusion molding of an aluminum material.

Further, the rubber material 12 is formed in a plate shape, and an engaging portion that engages with the guide groove 10a is formed at a side end thereof so as to protrude toward the guide 10 side. A part of the engaging portion is constricted and engaged with the return of the guide groove, whereby the rubber material 12 can be attached to the guide 10.
Moreover, the front-end | tip part 12a of the rubber material 12 has extended to the door stop part side of the vertical frame 3a. The tip end portion 12a has a cross-sectional C shape that is branched into two. And this branched front-end | tip part 12a is arrange | positioned between the vertical frame 3a and the high-speed door 1a.
When the high-speed door 1a is in the open state, as shown in FIG. When the high speed door 1a is fully closed, as shown in FIG. 5 (b), the C-shaped tip portion 12a is closed by overlapping, and the high speed door 1a and the vertical frame 3a are closed. Sandwiched between them. Thereby, the clearance gap between the high speed door 1a and the vertical frame 3a can be sealed now.
Further, when attaching or detaching the rubber material 12, the rubber material 12 can be attached to or detached from the guide 10 by sliding the engaging portion of the rubber material 12 from the end opening. Yes.

FIG. 6 shows a smoke shielding structure in a gap portion between the low speed door 1b and the high speed door 1a.
As shown in FIG. 6, a flat guide 13 and a rubber material 15 attached to the guide 13 are attached to the side surface of the high speed door 1 a on the low speed door 1 b side.
The guide 13 is formed in a flat plate shape extending in the vertical direction along the high-speed door 1a, and is attached to the lower end of the vertical frame 3a by screws 14 from the upper end. The end of the guide 13 on the low speed door 1b side is thick, and a guide groove 13a having an opening is formed in a straight line at the end. The opening of the guide groove 13 a is folded inward, and the end of the rubber material 15 fitted in the guide groove 13 a is engaged by this folding, so that the rubber material 15 is engaged with the guide 13. It can be attached. Further, both ends of the guide groove 13a are open, and the rubber member 14 can be slid and inserted from the end opening to be attached.

The rubber material 15 constitutes an engaging portion that engages with the folded portion of the guide groove 10a by constricting a part of the base end portion from both sides.
In addition, a concave portion 15a having a U-shaped cross section is formed on both surfaces (left and right in the drawing) at the base end portion of the rubber material 15. The lower end of the recess 15a is substantially flush with the entire surface of the high speed door 1a. By this concave portion 15a, when the rubber material 15 is bent in contact with the low speed door 1b, the concave portion 15a is bent around the concave portion 15a.
Moreover, the front-end | tip part of the rubber material 15 is extended and formed toward the bending part of the low speed door 1b. When the door 1 is fully closed, as shown in FIG. 6 (b), the front end abuts against the bent portion of the low speed door 1b, so that the gap between the high speed door 1a and the low speed door 1b can be sealed. It is like that.

FIG. 7 shows a smoke shielding structure in a gap portion between the low speed door 1b and the vertical frame 3b on the door pocket side.
As shown in FIG. 7A, the front surface of the low-speed door 1b on the side of the vertical frame 3b includes a flat plate guide 16 and a rubber material 18 attached to the guide 16.
The guide 16 is formed in a flat plate shape extending in the vertical direction along the side edge of the low-speed door 1 b and is attached to the low-speed door 1 b by a screw 17. The end of the guide 16 on the side in contact with the vertical frame 3b is thick, and a guide groove 16a opened on the side is formed in a straight line at the end. The opening of the guide groove 16a is folded inward, and the end of the rubber material 18 fitted in the guide groove 16a is engaged by this folding, so that the rubber material 18 is engaged with the guide 16. It can be attached. Both ends of the guide groove 16a are open, and the end of the rubber member 18 can be slid and inserted from the end opening.

The rubber material 18 is adapted to engage with the folded portion of the guide groove 16a by constricting a part of its end.
Further, a concave portion 18a having a U-shaped cross section is formed on both surfaces (upper and lower sides in the drawing) at the end portion of the rubber material 18, so that the thickness of the end portion of the rubber material 18 is partially reduced. A constriction is formed. Thereby, when the rubber material 18 is bent, the concave portion 18a is bent at the center.
The other end portion of the rubber material 18 rises obliquely toward the side end side (the left side in the drawing) of the vertical frame 3b, and the tip end portion extends toward the bent portion of the vertical frame 3b. As a result, when the door 1 is fully closed, the tip of the rubber member 18 comes into contact with the bent portion of the vertical frame 3b as shown in FIG. 7B, so that the airtightness between the low-speed door 1b and the vertical frame 1b is reached. Keeping sex.

In the door 1 formed as described above, the rubber material 12, the rubber material 15, and the rubber material 18 are respectively shown in FIGS. 5A, 6A, and 7A when the door 1 is open. ) Is open as shown.
From this state, when the door 1 is fully closed, the front end portions 12a and 12b of the rubber material 12 are sandwiched between the high speed door 1a and the vertical frame 3a between the high speed door 1a and the vertical frame 3a. The space between the high speed door 1a and the vertical frame 3a is sealed.
Moreover, as shown in FIG.6 (b), the overlap part between the high speed door 1a and the low speed door 1b seals this clearance by the front-end | tip part of the rubber material 15 contact | abutting to the low speed door 1b. At this time, the rubber material 15 is pushed by the low speed door 1b and bends around the constricted recess 15a, and the sealing performance is further enhanced by the force of the bend. Further, even if the rubber material 15 is bent, the stress can be released to the concave portion 15a, so that the rubber material 15 can be prevented from deteriorating.
Further, as shown in FIG. 7B, the gap between the low-speed door 1b and the vertical frame 3b is vertical to the low-speed door 1b because the tip of the rubber material 18 is in contact with the bent portion of the vertical frame 3b. The gap between the frame 3b is sealed. At this time, the rubber material 18 is bent around the concavity 18a by being pulled to the left side of the drawing by the low speed door 1b, and the sealing performance is further enhanced by the force of the bending. Further, even if the rubber material 18 is bent, the stress can be released to the concave portion 18a, so that the rubber material 18 can be prevented from deteriorating.

Thus, in the above-described example, the rubber members 12, 15, and 18 can be easily attached and detached by sliding and inserting from the opening ends of the guide grooves 10a, 13a, and 16a of the guides 10, 13, and 16. it can. Thereby, since the rubber materials 12, 15, and 18 can be made separate from the door 1, adjustment can be performed when the door 1 is installed, and the replacement thereof can be easily performed.
Moreover, since the guides 10, 13, and 16 can be manufactured by extrusion molding of aluminum separately from the door 1, the manufacturing cost can be reduced.

  FIG. 8 shows a structure for shielding the gap between the high-speed door 1a and the vertical frame 3a constituting the door holding portion, and is a guide attached to the back side (the hoistway side) of the vertical frame 3a. 21 and a rubber material 22 attached to the guide 21.

The guide 21 is in the form of a long plate attached from the upper end to the lower end of the vertical frame 3a with a screw (not shown). Is formed.
The guide groove 21a at the side end of the guide 21 is opened obliquely forward (in the drawing, obliquely upward) from the door stop side toward the high-speed door 1a side. Further, the guide groove 21b on the side surface portion of the guide 21 is opened obliquely rearward from the back surface of the frame body 3a. Each of these guide grooves 21a and 21b has an arcuate cross section at the bottom, and its opening is narrower than the arcuate diameter, so that the engaged rubber material 22 comes out against the pulling force. There is no such thing.

  Further, the rubber material 22 is formed in a plate shape extending from the upper end to the lower end of the guide 21, and both end portions thereof are formed in a thick arc shape. In addition, a convex portion 22a is formed in a straight line extending from the upper end portion to the lower end portion of the rubber material 22 at a substantially central portion on the back side of the rubber material 22, that is, on the back side of the door contact surface of the rubber material 22. . Then, the end portion of the rubber material 22 is slid and inserted from the end opening of the guide groove 21a, so that the end portion of the rubber material 21a is engaged with the engagement hole 21a and attached. Since the guide groove 21a is formed obliquely forward from the vertical frame 3a, the rubber material 21a is attached in a form protruding obliquely on the door-contact surface.

FIG. 9 shows another smoke shielding structure in the gap portion between the low speed door 1b and the high speed door 1a.
In FIG. 9, the above-mentioned guide 21 is attached to the side surface of the high-speed door 1a, that is, the side surface on the side overlapping with the low-speed door 1b.
In this example, the guide groove 21a is arranged from the front side of the high speed door toward the low-speed door 1b obliquely forward, and the other guide groove 21b is arranged obliquely forward from the side of the high-speed door 1a. ing.
Further, the rubber material 23 of this example has a plate shape in which both ends are formed in a circular arc shape. The both end portions of the wall thickness are engaged with the guide grooves 21a and 21b, respectively, so that the rubber material 23 is arranged in a curved ring shape. At this time, since the guide groove 21a is formed obliquely toward the low-speed door 1b and the guide groove 21b is formed obliquely forward from the side of the high-speed door 1a, the ring formed by the rubber member 23 is It becomes the form which was pulled by the low speed door 1b side and swelled. When the door 1 is in the fully closed state, one end of the swollen portion of the rubber material 23 comes into contact with the protruding portion on the back surface of the low speed door 1b, so that sealing can be provided. ing.

FIG. 10 shows another smoke shielding structure in the gap portion between the low speed door 1b and the vertical frame 3b on the door pocket side.
In FIG. 10, the guide 24 is attached to the side part front surface of the low speed door 1b on the door pocket side.
The guide 24 is formed with a guide groove 24a opened in parallel toward the closing movement direction of the low speed door 1b and a guide groove 24b formed so as to rise obliquely forward from the low speed door 1b.
And the edge part of the rubber material 23 is slid and engaged from the edge part opening of these guide grooves 24a and 24b. Thereby, since the rubber material 23 has the guide groove 24b formed obliquely forward, the ring formed by the rubber material 23 swells in the vertical frame 3b side (the direction of closing when the door is closed). Become.
When the door 1 is fully closed, the swollen portion of the rubber material 23 comes into contact with the protruding portion on the back surface of the low-speed door 1b, so that sealing can be provided. .

In the door 1 formed as described above, when the door 1 is open, the rubber material 22, the rubber material 23, and the rubber material 23 are respectively shown in FIGS. 8A, 9A, and 10A. ) Is open as shown.
When the door 1 is fully closed from this state, as shown in FIG. 8 (b), the tip of the rubber material 22 is sandwiched between the high speed door 1a and the vertical frame 3a, and the high speed door 1a The space between the vertical frame 3a is sealed. At this time, the convex portion 22a provided on the back surface of the rubber material 22 is pressed against the vertical frame 3a. At this time, since the convex portion 22a is formed, the contact pressure can be increased immediately before the high speed door 1a is fully closed. Thereby, the impact when the high-speed door 1a hits the door stop can be gradually weakened, the flexibility can be increased, and the life of the rubber material 22 itself can be extended.

Moreover, as shown in FIG.9 (b), the overlapping part between the high speed door 1a and the low speed door 1b is because the ring-shaped rubber material 23 contact | abuts the back surface of the low speed door 1b, and thereby the high speed door 1a. And the low-speed door 1b can be sealed.
Further, as shown in 10 (b), the gap between the low speed door 1b and the vertical frame 3b is such that the ring-shaped rubber material 23 comes into contact with the back surface of the vertical frame 3b, so The gap between the frame 3b can be sealed. Therefore, by making the rubber material 23 into a ring shape, it is flexible and the contact area can be increased, so that the sealing performance is improved, and the adjustment at the time of installing the door 1 and the rubber material 23 is facilitated.
In addition, when the rubber material 23 is replaced, the rubber material 23 can be removed from the guide groove, and the new rubber material 23 can be slid from the opening end of the guide groove and installed. .
Further, since the guides 21 and 24 are configured separately from the door 1, only the guides 21 and 24 can be formed separately by aluminum extrusion or the like.

A structure for shielding the gap between the upper frame 2 and the door 1 will be described.
FIG. 11 is a view showing a smoke shielding structure between the upper frame 2 and the high speed door 1a and the low speed door 1b.
In FIG. 11, the high-speed door 1a is attached by a door hanger 6a, and the low-speed door 1b is attached by a door hanger 6b so as to be movable in the direction perpendicular to the paper surface.
Further, the upper frame 2 is formed with standing portions at the traveling portions of the high speed door 1a and the low speed door 1b, and a guide 30 extending to the left and right is attached to the standing portion.
The guide 30 is formed in a plate shape, and a guide groove 30a is formed on the upper end portion thereof in a straight line on the left and right. Both end portions of the guide groove 30a are opened, and the rubber material 31 is attached by sliding the rubber material 31 from the end opening. Further, the upper opening of the guide groove 30a is folded toward the center of the opening so that the width of the opening is narrowed. The base end of the rubber material 31 is engaged with the guide groove 30a. Are configured to be attached.

  The rubber material 31 is formed in a plate shape, and a narrowed width is formed in the vicinity of the base end portion of the rubber material 31. The constriction of the base end portion is attached by engaging with the folding of the guide groove 30a. Further, the rubber material 31 is inclined such that the tip end portion extends obliquely forward. Thereby, the front-end | tip part of the rubber material 31 contact | abuts and adheres to the upper end part of the door 1. As shown in FIG.

  Moreover, the tape 31 is affixed in the left-right direction at each upper end part of the high speed door 1a and the low speed door 1b. The tape 32 is made of a member having a small friction coefficient, such as ultra high molecular weight polyethylene, and is in sliding contact with the tip of the rubber material 32.

When the high-speed door 1a and the low-speed door 1b move from such a configuration, the gap between the door 1 and the upper frame is arranged so that the rubber material 31 is inclined obliquely forward. The tip part of 31 contacts the upper end part of the high speed door 1a and the low speed door 1b. At this time, since the tape 32 is attached to the upper ends of the high speed door 1a and the low speed door 1b, even if the door 1 moves, the friction between the rubber material 31 and the high speed door 1a and the low speed door 1b is Less.
Therefore, even if the rubber material 31 is attached, it is possible to prevent the rubber material 31 from being deteriorated by hindering the movement of the door 1 or slidingly contacting the door 1. Further, even if the rubber material 31 is not subjected to the low friction processing, it is only necessary to attach an inexpensive low friction coefficient tape 31 to the door 1 side, so that the cost can be reduced.

In the example described above, an example in which the rubber material is formed in a plate shape and only one sheet is attached has been described. However, as shown in FIG. 12, the plate-shaped rubber material 31 may be provided in two stages in parallel.
In this case, the guide 30 is formed with two upper and lower guide grooves 30a for attaching the rubber material 31 by sliding.
A plate-shaped rubber material 31 is slidably attached to each guide groove 30a. Thereby, the rubber material 31 is attached in duplicate, and the airtightness can be further enhanced. In particular, when the gap between the low-speed door and the high-speed door is large and the contact area of the rubber material 31 is small, the contact area becomes large as a whole by making it double as shown in FIG. Can keep sex.
Note that the rubber material 31 does not necessarily need to be double, and when the width between the doors is narrow and the rubber material 31 can be sufficiently adhered, the rubber material 31 may be one in the structure of FIG. .

In the above-described example, an example in which the rubber material is formed in a plate shape has been described. However, instead, as shown in FIG. 13, the same applies to the case where the plate-shaped rubber material 34 is bent and arranged in a cross-sectional loop shape.
In this example, guide grooves with which the rubber material 34 is engaged are provided at two positions on the side surface of the guide 33 on the door 1 side, and the end portions of the rubber material 34 are respectively engaged with the guide grooves. The guide groove is provided in a straight line on the left and right sides of the guide 33 and opens obliquely upward, and the width of the opening is narrower than the width inside the groove.
Then, the rubber material 34 is slid and attached from the end opening of the guide groove while the rubber material 34 is bent in a cross-sectional loop shape. As a result, the loop-shaped tip end portion of the rubber material 34 comes into contact with the tape 32 attached to the upper end portion of the door 1 to seal the gap between the upper end portion of the door 1 and the upper frame 33. be able to. Even in such a configuration, the same effect as in the example of FIG. 11 described above can be obtained.

Further, when the rubber materials 31 and 34 are arranged between the upper frame 2 and the door 1 as described above, when the high speed door 1a is moved from the fully opened state and is closed, the end portion of the high speed door 1a is a rubber material. The end portions of the rubber materials 31 and 34 may be caught and the rubber materials 31 and 34 may be rolled up, or the end portions of the rubber materials 31 and 34 may collide with the high speed door 1a, and the rubber materials 31 and 34 may not function.
In order to prevent this, as shown in FIGS. 14 and 15, a resin guide 35 is attached to the open upper end portion of the high-speed door 1a with a screw or the like.
The resin guide 35 is formed so as to extend in the closing direction of the high-speed door 1a. The width of the resin guide 35 gradually decreases toward the tip, and the upper end surface of the resin guide 35 is inclined downward. The tip of the resin guide 35 is chamfered and smooth.

With this configuration, when the high-speed door 1a is closed from the fully open state, the upper end portion from the front end of the resin guide 35 comes into contact with the end portions of the rubber materials 31 and 34. At this time, the distal end portion of the guide 35 is chamfered to be a smooth surface, and is inclined downward toward the distal end portion, so that the resin guide 35 is moved along with the movement of the high speed door 1a. The rubber materials 31 and 34 are pushed up and restricted to the positions shown in FIGS.
As a result, it is possible to prevent the high-speed door 1a from being caught by the rubber materials 31 and 34 to prevent the airtightness from being maintained.

An example in which an end closing material is provided to close the gap between the low speed door 1b and the upper end of the vertical frame 3b on the door pocket side is shown in FIG.
As shown in FIG. 16, an upper end closing member 36 is attached to the upper end portion of the vertical frame 3b. The upper end closing member 36 has a rectangular parallelepiped shape. The upper end closing member 36 is attached so as to close the upper end opening of the guide provided in the vertical frame 3b of FIG. 7 or FIG.

  Thus, according to the example shown in FIG. 16, when the end closing member 36 is attached to the upper end of the vertical frame 3b, when the low speed door 3b is fully closed, the low speed door 3b and the vertical frame 3b. The upper opening between the two can be closed, and airtightness can be maintained.

A structure for sealing the gap between the door 1 and the sill 4 will be described.
17 and 18, a bracket 103 for attaching the guide shoe 101 is screwed to the lower end portion of the door 1. The bracket 103 is bent in two steps in a stepped manner, and is attached to the opening at the lower end of the door 1 with a screw or the like. A guide shoe 101 is attached to the lower end of the bracket 103 with screws.
Further, a guide shoe 101 is attached to a portion of the lower end portion of the bracket 103 that extends to the front side with a left-right interval.
A plate-like guide 32 is attached to the front end of the lower end portion of the bracket 103 so as to extend left and right along the bracket 103 and along the lower end surface of the door 1.
The guide 32 has a guide groove 32a for attaching the rubber material 31 at the lower end thereof, and is formed in a straight line on the left and right. The guide groove 32a is formed in an arc shape in cross section, and the width of the lower opening is formed smaller than the inner diameter.
The rubber material 31 is formed in a plate shape, and its upper end is formed in a cross-sectional arc shape in accordance with the shape of the guide groove 32a, and its diameter is larger than the upper portion of the rubber material.
Thereby, the rubber material 31 can be attached to the guide groove 32a by inserting the upper end portion of the rubber material 31 by sliding it from the end opening of the guide groove 32a.

The upper end of the sill 4 is provided with a groove 41 for moving the guide shoe 101 in a straight line on the left and right sides thereof and a groove 42 provided in parallel with the groove 41.
The groove 41 and the groove 42 are provided over the range in which the high-speed door 1a and the low-speed door 1b move, respectively.
The guide shoe 101 is disposed in the groove 41 and the lower end portion of the rubber material 31 is disposed in the groove 42. Thereby, the guide shoe 101 can be opened and closed while being regulated forward and backward by the groove 41. Moreover, the clearance gap between the door 1 and the sill 4 can be sealed because the rubber material 31 closely contacts the groove 42 side.

Another structure for sealing the gap between the door 1 and the sill 4 will be described.
19 and 20, a bracket 104 for attaching the guide shoe 101 is screwed to the lower end portion of the door 1. The bracket 104 is bent in two steps in a stepped manner, and is attached to the opening at the lower end of the door 1 with a screw or the like.
A guide shoe 101 is attached to the portion of the lower end portion of the bracket 104 that extends to the front side with a left-right spacing.

In addition, a plate-like guide 302 is attached to the lower end portion of the bracket 104 with a presser fitting 106.
The guide 302 extends to the left and right along the bracket 104 and is attached to the entire surface along the lower end surface of the door 1. At the lower end of the guide 302, a guide groove 302a for attaching the rubber material 31 is formed in a straight line on the left and right. The guide groove 302a is formed in an arc shape in cross section, and the width of the lower opening is formed smaller than the inner diameter. Further, a groove 302b that engages with the lower end portion 106b of the presser fitting 106 is formed on the back side (the hoistway side) of the guide 302.

Further, as shown in FIGS. 19 and 20, the holding metal fitting 106 is provided in the central portion of the bracket 104. The presser fitting 106 is formed such that a lower end portion 106b is bent in an L-shaped cross section and protrudes leftward in FIGS.
The presser fitting 106 is formed with a vertically long hole 106 a for screwing the presser fitting 106. The presser fitting 106 can be screwed to the bracket 104 by screwing the screw 105 into the elongated hole 106a. The presser fitting 106 can move up and down along the long hole 106a in a state where the screw 105 is loosened.
Then, the guide 302 can be attached to the pressing metal 106 by being engaged with the groove 302b of the guide 302 and sliding from the end of the lower end 106b of the pressing metal 106.
Further, the rubber material 31 is formed in a plate shape, and its upper end is formed in a cross-sectional arc shape in accordance with the shape of the guide groove 302a, and its diameter is larger than the upper portion of the rubber material.
Thereby, the rubber material 31 can be attached to the guide groove 302a by inserting the upper end portion of the rubber material 31 by sliding it from the end opening of the guide groove 302a.
Therefore, the guide 302 and the rubber material 31 can be moved up and down while the guide 302 and the rubber material 31 are attached to the lower end portion 106b of the presser fitting 106.

In addition, a groove 41 for guiding the movement of the guide shoe 101 and a groove 42 for guiding the rubber material 31 provided in parallel to the groove 41 are formed on the upper end of the sill 4 in a straight line on the left and right. Is provided.
The groove 41 and the groove 42 are provided over the range in which the high-speed door 1a and the low-speed door 1b move, respectively.
The guide shoe 101 is disposed in the groove 41, and the lower end portion of the rubber material 31 is disposed in close contact with the groove 42. Thereby, the guide shoe 101 can be opened and closed while being regulated forward and backward by the groove 41. Further, since the rubber material 31 is in close contact with the inner wall of the groove 42, the contact area between the rubber material 31 and the inner wall of the groove 42 can be increased, and the gap between the door 1 and the sill 4 can be sealed. .

Thus, in the above-described embodiment, when the door is installed, the press fitting 106 is retracted upward along the long hole 106a with the screw 105 loosened. As a result, as shown in FIG. 21, the guide 302 and the rubber material 31 attached thereto are also retracted upward, and the rubber material 31 does not protrude from the lower end of the door. In this state, the door is installed such that the guide shoe 101 is fitted into the groove 41.
When the installation of the door is completed, the screw 105 and the presser fitting 106 are pushed down along the long hole 106a. Thereby, the rubber material 31 advances into the groove 42 as shown in FIG. When this state is reached, the screw 105 is tightened to fix the mounting bracket 106. Thereby, the rubber material 31 is also fixed in close contact with the groove 42.

Thus, according to the above-described example, when the door is installed, the rubber material 31 is temporarily retracted into the lower end portion of the door, and when the door is installed, the mounting bracket 106 is moved downward along the long hole 106a. Since the rubber material 31 is arranged in the groove 42, the rubber material 31 can be prevented from being damaged and the airtightness being lost when the door is installed.
Further, it is not necessary to position and slide the guide shoe 101 and the rubber material 31 simultaneously at the time of installation, and it is only necessary to position the rubber material 31 after positioning the guide shoe, so that the installation effort can be reduced.
Further, when replacing the rubber material 31, the screw 105 is once loosened and retracted, the rubber material 31 is slid and pulled out from the opening end, and the new rubber material 31 is slid again from the opening end and attached. Therefore, the replacement can be easily performed without replacing or removing the entire door.

In the examples shown in FIGS. 19 to 22 described above, the example in which the groove 42 is provided on the side of the sill 4 has been described. However, the guide shoe on the floor side is not provided as shown in FIGS. 23 and 24. An inclined surface 43 may be provided at the upper end portion of the groove 41 into which 101 is fitted, and the rubber material 31 may be in contact with the inclined surface 43. In this case, the rubber material 31 is formed to be inclined obliquely toward the groove 41 so that the tip of the rubber material 31 abuts the inclined surface 43 when the rubber material 31 is installed.
In addition, about the same structure as the example shown in the above-mentioned FIGS. 19-22, the same code | symbol is attached | subjected and description is abbreviate | omitted.
In this example, when the door is installed, the presser fitting 106 is retracted upward along the long hole 106a with the screw 105 loosened. Accordingly, as shown in FIG. 23, the guide 302 and the rubber material 31 attached thereto are also retracted upward, and the rubber material 31 does not protrude from the lower end portion of the door. In this state, the door is installed such that the guide shoe 101 is fitted into the groove 41.
When the installation of the door is completed, the screw 105 and the presser fitting 106 are pushed down along the long hole 106a. As a result, the rubber material 31 is formed so as to be inclined toward the groove 41, so that the rubber material 31 comes into close contact with the inclined surface 43 of the groove 41 as shown in FIG. In this state, the screw 105 is tightened to fix the mounting bracket 106. Thereby, a door comes to move in the state which the rubber material 31 contact | abutted to the inclined surface 43, and it can shield.
Moreover, since it is not necessary to provide a groove on the sill side, it is possible to reduce the trouble of fitting the rubber material 31 into the groove during installation, and it is possible to reduce the cost.
Further, even if the rubber material 31 deteriorates due to sliding contact with the inclined surface 43, only the rubber material 31 may be slid from the guide 302 and removed from the open end, and a new rubber material 31 may be slid and attached. Therefore, only the rubber material 31 can be replaced easily and at low cost.

The structure for shielding the clearance gap between the high speed door 1a and the low speed door 1b of the lower end part of the door 1 is demonstrated.
As shown in FIGS. 25 and 26, a rubber material 51 and a rubber material 52 for closing the end are attached to the upper end between the high speed door 1a and the low speed door 1b.

The rubber material 52 has a thin cubic shape, and is attached to the end of the guide groove of the low-speed door 1b (the end when the low-speed door is fully closed) orthogonal to the guide groove. And the rubber material 52 comes into contact with the lower end of the low speed door 1b when the low speed door 1b is fully closed. The rubber material 52 has a width larger than the width of the guide groove, and protrudes to the back side from the guide groove.
When the door 1 is fully closed as shown in FIG. 25 (b), the side end portion of the rubber material 51 comes into contact with the portion of the rubber material 52 once, and this gap is sealed.

By appropriately combining the structures described in the above embodiments, the gap between the doors 1 of the elevator can be sealed.
Thereby, even when a fire or the like occurs, it is possible to prevent smoke from leaking from the gap between the doors of the elevator and the gap between the door and the frame or the sill.
Moreover, according to the above-mentioned embodiment, since a rubber material etc. are members different from the door 1, cost becomes cheap and the adjustment at the time of providing the door 1 also becomes easy. In addition, rubber material can be attached by sliding it from the opening end of the guide groove, so it is easy to attach, and it is difficult to come off just by pulling it from the front. Can be obtained.
Further, when the rubber material deteriorates due to long-time use, etc., it is only necessary to replace the rubber material, and the operation is simple and the cost is reduced.
