Description

  Embodiments of the present invention relate to a door system for a high lift elevator.

  In a high lift elevator installed in a high-floor building, the air warmed inside the building in winter when the temperature difference between inside and outside the building is lower than the outside air, the air density is lower than the outside air. There is a case where air flows from the lower floor to the upper floor via the hoistway. If the building is completely sealed, the updraft is unlikely to occur, but in reality, the updraft is generated in the hoistway because it is in contact with the outside air by ventilation. In the past, revolving doors were installed on the ground floor to prevent the inflow of outside air. However, in recent years, buildings with a structure that prevents the inflow of outside air by installing multiple normal automatic doors instead of revolving doors from the viewpoint of safety. There are many. In this case, since there are situations where a plurality of automatic doors are open at the same time, the airtightness of the revolving door is not obtained, and the rising airflow (draft) phenomenon through the hoistway often occurs.

  When a draft is generated, air flows into the hoistway from the building landing on the lower floor, and airflow from the hoistway to the building landing occurs on the upper floor. The opening / closing load becomes larger than usual, and the load on the drive unit when the door is opened and closed is increased.

  There are proposed elevators that reduce the noise level in the elevator car (for example, see Patent Document 1), and elevators that are not easily deformed even when external pressure is applied from a direction other than the door opening and closing direction (for example, Patent Document 2) is not in terms of reducing the load on the drive unit.

  On the upper floor of the building, there is an air flow from the hoistway to the building landing side, but immediately before the door is fully opened, an air current that passes through between the car door and the enclosure wall is generated, and a force that pushes the door in the closing direction is generated. However, depending on the size of the airflow, there may be a problem that the door cannot be opened completely by the driving force of the motor.

The car door 4 has a car door panel 5, and the door bag side end surface 6 of the car door panel 5 is not perpendicular to the front of the panel but has an angle exceeding 90 degrees. That is, the end surface on the door pocket side of the door panel is not perpendicular to the opening and closing direction but is inclined.

  According to the first embodiment, when air flows from the hoistway to the building landing side on the upper floor of the building, the door closing direction component of the force that pushes the door end surface 6 of the car door panel 5 decreases. . As a result, the driving force required for opening the door can be reduced.

(Second Embodiment)
Next, a second embodiment will be described. FIG. 2 is a high elevation elevator door system according to the second embodiment, and is a plan view of an elevator door having a double opening structure as viewed from above. FIG. 3 is an enlarged view of the right door panel portion shown in FIG.

  In FIG. 2, an elevator car room 2, a car door 4 installed in an elevator car that moves up and down the hoistway, and a landing door 3 installed at the landing opening of the hoistway are arranged inside the hoistway wall 1 of the building. ing. The door system includes a door driving device (not shown) that is connected to an opening / closing mechanism of the car door 4 to open and close the car door 4 and an engagement device (not shown) that transmits the driving force of the car door 4 to the landing door 3. ing.

  As shown in FIG. 3, the door bag side end face 6 of the car door panel 5 is perpendicular to the front face of the panel. A wind regulation member 7 is attached to the end surface 6 on the door pocket side of the car door panel 5.

  The air conditioning member 7 is inclined rather than perpendicular to the front of the car door panel 5.

  The air conditioning member 7 is attached over the entire height of the car door panel 5. However, when a product such as a phototube is attached to a part of the door pocket side end face 6, it is possible to divide the part and attach it vertically.

  According to the second embodiment, when an air flow from the hoistway to the building landing side occurs on the upper floor of the building, the door closing direction component of the force that pushes the door end surface 6 of the car door panel 5 decreases. . As a result, the driving force required for opening the door can be reduced.

(Modification)
Next, a modified example of the air conditioning member 7 will be described. 4 and 5 are views showing examples in which the shape of the air conditioning member 7 shown in FIG. 3 is changed.

  The air conditioning member 7a shown in FIG. 4 has a planar shape, that is, a shape in which the central portion projects toward the hoistway wall. Although the air conditioning member 7 shown in FIG. 3 reduces the door closing direction component when receiving wind force, it generates a component force that presses the door panel 5 against the cab 2 side. Running resistance may increase. Since the air conditioning member 7a shown in FIG. 4 has a shape in which the center protrudes, there is an effect of reducing the component of wind force in the door closing direction and not generating a force for pressing the car door panel 5 to one side.

  The air conditioning member 7b shown in FIG. 5 is obtained by reversing the direction of inclination with the air conditioning member 7 shown in FIG. The air conditioning member 7 is not perpendicular to the opening / closing direction of the car door 4 but is inclined to the opposite side of the landing door 3, and the second air conditioning member 7 b is attached to the door pocket end surface of the landing door panel 8. The inclined surface of the second air conditioning member 7b and the inclined surface of the air conditioning member 7 are in opposite directions. According to such a shape, although the component which presses the car door panel 5 toward the landing side is generated, there is an effect of reducing the airflow flowing into the space between the car door panel 5 and the landing door panel 8. Therefore, there is an effect of reducing the generation of pressing force in the door closing direction when the airflow flowing into the gap hits the door safety shoe 9 protruding from the car door panel, for example.

(Third embodiment)
Next, a third embodiment will be described. FIG. 6 is a high elevation elevator door system according to the third embodiment, and is a plan view of an elevator door with a single opening structure as viewed from above. FIG. 7 is an enlarged view of the door panel portion shown in FIG.

  In FIG. 6, an elevator car room 2, a car door 4 installed in an elevator car that moves up and down the hoistway, and a landing door 3 installed at a landing opening of the hoistway are arranged inside the hoistway wall 1 of the building. ing. The door system includes a door driving device (not shown) that is connected to an opening / closing mechanism of the car door 4 and opens and closes the car door, and an engagement device (not shown) that transmits the driving force of the car door 4 to the landing door 3. Yes.

  As shown in FIGS. 6 and 7, a wind regulation member 7 c is attached to the door bag side end face 6 of the car door panel 5, and the wind regulation member 7 c has a planar shape in which the side facing the car room 2 protrudes. With such a structure, when an air flow from the hoistway to the building landing side occurs on the upper floor of the building, the door closing direction component of the force pushing the door end side surface 6 of the car door panel 5 is reduced. At the same time, by reducing the airflow flowing between the high-speed side panel and the low-speed side panel of the single door, there is an effect of smoothly flowing the staying airflow, and the driving force required for opening the door can be reduced. Become.
