Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator hall door device.

[0002]

2. Description of the Related Art Conventionally, as a device of this type, as described in Japanese Laid-Open Publication No. 93-23511 (published on 1993.8.16), first and second panels of a landing door, and a second panel of a landing door. A door shoe attached to the first and second panels by connecting the panel and the door pocket individually through a sliding body, engaging with a sill groove that guides traveling when the first panel and the second panel are opened and closed, and attached to the first and second panels. It is known to eliminate this.

[0003]

However, in the above-mentioned conventional apparatus, the amount of engagement (length) of the sliding body between the first panel and the second panel, between the second panel, and between the second panel and the door pocket is large. Minimum when the door is fully closed. Therefore, the force to hold the position of the door when the door is fully closed is insufficient, and even if you lightly push the door from the landing side, it will sway, and if you lean on it or push it intentionally, It was unavoidable that it would be very dangerous to move to the roadside.

It is an object of the present invention to provide an elevator landing door device having no sill groove and door shoes, which can prevent a dangerous state of moving to the hoistway side even if the door panel when fully closed is pushed. To provide a door device.

[0005]

[Means for Solving the Problems] The above object is to have an entrance / exit opening at the boundary between an elevator hoistway and a landing, and a three-way frame is attached to the three lines of the entrance / exit opening so that the opening / closing can be freely performed. In a hall door device for an elevator in which a hall door including one or more door panels is arranged, a support formed on the other side of the three-way frame and a back side of the hall door, one end of which is one side of the three-way frame Is rotatably supported by
And when the other end of the landing door is fully closed, the door support rod has a length such that it engages with the other side of the three-way frame, and when the door is fully closed, the door support rod crosses the opening and the other end supports and receives. And a means for interlocking the door panel and the door support rod so that the other end of the support rod is retracted from the opening and rotated to the back side of the door panel when the door is fully opened. It is achieved by adopting a different configuration.

[0006]

As described above, in the elevator landing door device having no sill groove and door shoe, the door support bar arranged on the back side of the door panel lies from one side of the three-sided frame to the other side when the door is fully closed, and the opening is opened. I decided to cross it,
Even if the door panel is pushed from the landing side, the door supporting bar prevents the door panel from moving to the hoistway side in a dangerous state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIGS. 1 and 3 are rear views of the elevator landing door device as seen from the hoistway side, and FIG. 2 is a plan view as seen from above. 1 is an elevator hall, 2 is an elevator hoistway, 3 is a wall provided at the boundary between the hall 1 and the hoistway 2, 4 is an entrance opening formed in the wall 3, and 5 is both an entrance opening 4 A three-sided frame provided on the vertical and upper three edges, 6 is a door panel of a landing door, 7 is a door hanger attached to an upper portion of the door panel 6, and 8 is a door rail supported by the wall 3.
Reference numeral 9 is a sliding member provided between the door pocket portion of the wall 3 and the door panel 6, and is a guide 9 attached to the door pocket at an intermediate height position.
A, a slider 9B engaged with the guide 9A, and a slider 9
It is composed of a rod 9C connecting B and the door panel 6.
Reference numeral 10 denotes a door support bar which is arranged on the back side of the door panel 6 and whose one end 10A is rotatably supported with one side floor surface of the three-sided frame 5 as a fulcrum, and 11 is a support bar arranged on the other side of the three-sided frame 5.
Reference numeral 2 denotes an interlocking means of the door supporting rod 10 and the panel 6, which is a long groove 12A formed on the back surface of the door panel 6 with a slight inclination with respect to the vertical, and a long groove 12A which is connected to the door supporting rod 10 and whose tip is the long groove 12A. 1 inserted into and engaged with
It consists of 2B. Since a well-known mechanism is used as it is as a mechanism for driving the door panel 6 to open and close, illustration and description thereof will be omitted here. Next, the movement of each part when opening and closing the door panel 6 will be described. When the door is opened from the fully closed state in FIG. 1, a force in the direction of arrow A is applied to the door panel 6 by the door drive mechanism. This causes the door panel 6 to move in the direction of the arrow while being hung on the door rail 8 via the door hanger 7. At this time, the door panel 6 opens in the vicinity of the middle part thereof in a state where movement in the front-rear direction (with respect to the hall 1) is restricted. Also, the door support rod 10 is
When the long groove 12A and the projection 12B are traversing the opening 4 from the state of being traversed in the direction of the arrow B and the door panel 6 is fully opened, the door support bar 10 is erected (vertically) as shown in FIG. ) State, and is in a state of being retracted outside the opening 4, that is, in the door pocket portion. When the door is closed from the fully opened state shown in FIG. 3, a force is applied to the door panel 6 in the direction of arrow C, whereby the door panel 6 is closed. At this time, as the door panel 6 moves, the door support rod 10 falls toward the opening 4 and the door panel 6 is fully closed. As shown in FIG. 1, the door support rod 10 becomes substantially horizontal and opens. 4 and the other end engages the support 11. As a result, even if the door panel 6 is strongly pressed from the hall 1 side, the door support rod 10 causes the door panel 6 to be pushed.
The movement in the front-rear direction with respect to the hall 1 is blocked. According to the above-described embodiment, when the door is fully closed, the door is pushed from the landing side and the door is moved to the hoistway side, and the hoistway and the landing are in contact with each other. Can be prevented from falling into the hoistway.

[0008]

As described above, according to the present invention, in an elevator landing door device having no sill groove and door shoes, even when the door panel is fully closed, the door panel is moved to the hoistway side and is in a dangerous state. It is possible to provide a landing door device for an elevator that can prevent the above.
