Description

  The present invention relates to a landing door device, and more particularly to a single-opening landing door device.

  The conventional single door type elevator door panel has a problem that when the heat from a fire or the like is applied, the door end side is bent and the heat resistance performance is not always sufficient. If the single door type elevator door panel is deformed, the door panel and the car may collide or the door panel may come off.

  Therefore, it has been desired to take measures against heat of the single door type elevator door panel.

  The present invention has been made in view of the above-described needs, and an object of the present invention is to provide a landing door device that reduces deformation due to heat on the door-to-door side of a single-open elevator door panel.

  A landing door device according to the present invention includes a three-way frame including a vertical frame on the door stop side and a single-opening landing door panel.

  In the landing door device according to an embodiment of the present invention, a recess including a surface with which the side surface of the door-opening side door panel abuts when the door is closed is provided on the hoistway side of the door-holding vertical frame. A projecting member projecting in a direction parallel to the upper frame of the three-sided frame is provided on the door contact side of the recess. An opening portion into which the protruding member is inserted when the door is closed is formed on a side surface of the door opening side of the one-sided landing door panel.

  In a landing door device according to another embodiment of the present invention, a recess including a surface with which the side surface of the door-opening side door panel abuts when the door is closed is provided on the hoistway side of the door-holding vertical frame. A plate piece is attached to the side surface of the door-holding side vertical frame on the hoistway side. When the door is closed, the door contact side end of the one-way landing door panel moves between the plate piece and the surface of the door contact side vertical frame facing the hoistway.

  In the landing door device according to yet another embodiment of the present invention, a groove is formed in the longitudinal direction of the door-holding side vertical frame of the door-contacting side vertical frame. Is housed in a groove formed in the vertical frame on the door stop side.

  ADVANTAGE OF THE INVENTION According to this invention, the landing door apparatus which reduces the deformation | transformation by the heat | fever on the door stop side of a single swing type elevator door panel is provided.

It is the front view which looked at the embodiment of the elevator platform to which the present invention is applied from the platform side. It is the perspective view which looked at the door stop side vertical frame and high-speed door panel in one Embodiment by this invention from the hoistway side. It is sectional drawing which looked at the lower part of the door stop side vertical frame and high-speed door panel in one Embodiment by this invention from the hoistway side. It is the perspective view which looked at the door stop side vertical frame and high-speed door panel in other embodiment by this invention from the hoistway side. It is the front view and top view which looked at the lower part of the door stop side vertical frame and high-speed door panel in other embodiment by this invention from the hoistway side. It is the perspective view which looked at the door stop side vertical frame and high-speed door panel in other embodiment by this invention from the hoistway side. It is a top view of the door stop side vertical frame and high-speed door panel in further another embodiment by this invention.

  Hereinafter, exemplary embodiments will be described as appropriate with reference to the drawings. FIG. 1 is a front view of an embodiment of an elevator hall to which the present invention is applied as viewed from the hall side. The figure shows a landing in a state where a two-piece single-opening landing door is closed. Three-side frames 102 are provided on both sides and the upper part of the landing entrance. The three-sided frame 102 includes a door-holding vertical frame 104 provided on one side of the landing doorway, a door-bag vertical frame 106 provided on the other side of the landing doorway, a door-holding vertical frame 104 and a door pocket. And an upper frame 108 provided horizontally between the upper ends of the side vertical frames 106.

  The entrance / exit is opened and closed by a high-speed door panel 110 and a low-speed door panel 112 which are two single-opening type landing doors that move in the entrance direction of the entrance / exit. When the door is opened and closed, the high speed door panel 110 moves about twice as fast as the low speed door panel 112.

  Although not shown, a header case provided with a mechanism for opening and closing the high speed door panel 110 and the low speed door panel 112 is attached to the hoistway side above the upper frame 108 of the three-way frame 102 provided at the entrance side entrance of the elevator. ing. A guide rail is fixed to the header case in parallel with the door opening / closing direction. A door hanger is fixed to the upper part of each of the high-speed door panel 110 and the low-speed door panel 112, and a hanger roller is provided on the upper part of these door hangers. The hanger roller rolls on the guide rail. That is, the high-speed door panel 110 and the low-speed door panel 112 move in the opening / closing direction while being suspended from the guide rail via the hanger roller and the landing-side door hanger.

  A plurality of guide shoes 114 are provided below the high speed door panel 110, and a plurality of guide shoes 116 are provided below the low speed door panel 112. The high-speed door panel 110 and the low-speed door panel 112 move on the landing thresholds that are arranged to be shifted from each other in the thickness direction of the door panels 110 and 112, respectively. In the example shown in the drawing, when the high-speed door panel 110 and the low-speed door panel 112 are opened and closed, the guide shoe 114 slides in the groove of the landing threshold 118 disposed on the hoistway side, and the guide shoe 116 is disposed on the landing side. Slide in the groove on the landing threshold 120.

  Note that the high-speed door panel 110 and the low-speed door panel 112 open and close only when it is confirmed that the car 102 has arrived at the landing floor and stopped, and is normally closed.

(First embodiment)
Next, a first embodiment of a landing door device according to the present invention will be described. The perspective view which looked at the door stop side vertical frame 104 and the high-speed door panel 110 in this embodiment from the hoistway side is shown in FIG. Here, the figure shows a state in which the high-speed door panel 110 is slightly opened. On the high speed door panel 110 side of the door stop side vertical frame 104, a recess formed by a door contact side surface 202a perpendicular to the opening and closing direction of the high speed door panel 110 and a side surface 202b parallel to the opening and closing direction of the high speed door panel 110 is formed. . Protruding members 204a and 204b projecting in a direction parallel to the upper frame 108 of the three-way frame 102 are fixed to the lower end side and the upper end side of the door contact side surface 202a of the door contact side vertical frame 104, respectively. Next, as will be described with reference to FIG. 3, the protruding members 204a and 204b are inserted into openings provided in the high-speed door panel 110 when the door is closed.
