Abstract

<P>PROBLEM TO BE SOLVED: To guide a door at its lower end without the need for a door leg guide groove in the upper face of a sill. <P>SOLUTION: A link 4 fully ranging over the width of the door and a shaft 4c mounted on the sill and fully ranging over the width of the link are supported at the lower end of the door 12 by a bearing so that the door can be guided without vibrating in the horizontal direction. This eliminates the need for the guide groove in the upper face of the sill to guide the leg of the door. The sill has no guide groove and so no sill is required for a door case, resulting in the inexpensive sill having a reduced total length. No guide groove avoids a trouble of a door closing device due to dust clogged in a sill groove. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a technique for guiding a door lower end of a door closing device.

Conventionally, the doorway is opened and closed by a plate door. The plate door is hung on a rail provided at the upper edge of the entrance through a hanger roller, and is opened and closed by a door closing drive. From the lower edge of the door, the door leg protrudes downward. The door leg is inserted into a guide groove on the upper surface of the sill provided at the lower edge of the doorway. When the doorway door is opened and closed, the lower part of the door is guided to the guide groove via the door leg (see, for example, Patent Document 1).
In addition, the guide groove on the upper surface of the sill is fearful, so there was a groove on the upper surface of the sill on the lower surface of the sill, and the door legs were extended from the upper surface of the sill to the groove on the lower surface of the sill (for example, patent document 2).

JP-A-11-240683 JP-A-3-232683

In the door closing mechanism of Patent Document 1, there is a problem that an elderly person or a handicapped person crawls because there is a groove for guiding the door leg on the upper surface of the sill. In addition, there is a problem that the door leg is caught by the dust accumulated in the guide groove, causing a failure of the door closing mechanism.
In the door closing mechanism of Patent Document 2, there is no guide groove on the upper surface of the sill, so that the door does not crawl. However, because the door leg bends to the front of the sill and enters the bottom of the sill, a notch through which the door leg passes through the apron under the sill is required in the horizontal direction. There was a risk of being caught.

  The present invention has been made to solve such problems, and in an elevator door closing device having a plurality of doors, hanger rollers, rails, and a driving device, the lower end of the door and the sill are connected by a guide link to be guided. It is a thing.

As a result, the guide groove on the upper surface of the sill can be eliminated, and the number of accidents of burning can be reduced.
Compared with the door leg guide groove on the underside of the sill, there is no door leg to turn to the underside of the sill, so there is no need for a horizontal notch in the front sag. Safety can be improved without being caught.

Embodiment 1.
1 is a front view of a car doorway according to Embodiment 1 of the present invention, and shows a door fully closed, FIG. 2 is a front view of a car doorway of FIG. 1, and a door is fully opened, FIG. 3 is a perspective view of FIG. FIG. 3 is a perspective view of FIG. 2.
In the figure, 1a is a car entrance / exit pillar, 1b is a car door column, 1c is a car sleeve wall, 1d is a car operation panel, 2 is a high speed door, 2a is a notch, 3 is a low speed door, 3a is a notch, Guide link, 4a is a link member, 4b is a link member, 4c is a shaft, 4d is a bearing, 5 is a guide link, 5a is a link member, 5b is a link member, 5c is a bearing, 6 is a sill, 7 is a front droop (apron) , 8 is a floor plate, 9 is a front beam, 14 is a door closing device girder, 15 is a door closing drive motor, 15a is a motor pulley, 16 is a hanger roller mounting plate, 17 is a hanger roller, 18 is an up thrust roller, 19 is a high-speed door drive pulley, 20 is a low-speed door drive pulley, 21 is a drive pulley, 22 is a door rail, 23 and 24 are rope stop plates, and 25 and 26 are transmission ropes.

In this example, the example which employ | adopted this plan for the 2S door closing device (two-door single swing door) is shown.
Each door is connected to the sill with a guide link, and the guide link is configured to follow the opening and closing direction of the door without resistance, and each link member is formed to the full width of the door excluding the front and back plates. The length of the shaft can also support the full width of the link member. As a result, the link can guide the door while suppressing lateral deflection.

  Since the present invention is configured as described above, the following effects can be obtained.

Since the guide link connects the interior of the door and the sill of the door pocket on the back of the door, the door can be guided invisible to the passengers. For this reason, the groove | channel which guides the leg of a door on the sill upper surface is unnecessary, and the whisper in a sill groove | channel can be eliminated.
Moreover, since there is no guide groove of the door leg in the sill unlike the conventional door closing device, the sill is unnecessary in the door pocket portion. For this reason, the threshold length can be shortened. As a result, it is possible to reduce the groove processing cost of the sill and the material cost of the sill.
Moreover, since there is no sill groove, failure of the door closing mechanism due to dust clogged in the groove can be prevented.

In this example, an example of a car door is shown, but the illustration is omitted, but it can be applied to a landing door as well. When applied to a landing door, a guide mechanism is arranged on the hoistway side of the door so that the guide mechanism cannot be seen from the landing.
