Description

  TECHNICAL FIELD The present invention relates to an elevator hanger plate and an elevator door device including the same, and more particularly to an elevator hanger plate that can increase the rigidity of the hanger plate and prevent the elevator door from being detached due to deformation of the hanger plate. The present invention relates to an elevator door device including

  Conventionally, the safety standards related to the separation of elevator doors due to external impacts have not been sufficient. For example, in the case of the conventional EN (European standard) standard, a method in which a load of 30 kg is statically applied to the elevator door to check whether the door is deformed or not is used. However, since such a method cannot appropriately reflect the actual collision situation, there is a problem that the safety of the elevator door cannot be sufficiently secured.

  Along with this, at the recently held International Standardization Conference on Elevator Safety (ISO / TC178), the kinetic energy of an object that moves closest to the actual collision situation in relation to the “separation strength and test method” of the elevator door It was agreed that the method of adding to the door would be done in parallel. Accordingly, in order for the elevator door to receive confirmation of its stability, 450 [J] of energy (energy when two junior high school students (120 kg) rush and collide at a speed of about 10 km / h) Even if added, it is necessary that the elevator door does not leave.

  However, in the case of a conventional elevator door device, there is a problem that when the energy as described above is applied to the elevator door, the elevator door is easily detached due to deformation of the hanger plate.

  FIG. 9 is a side view of a conventional elevator door device for explaining the separation of the elevator door due to the bending of the hanger plate that may occur when a certain force is applied to the elevator door.

  A conventional elevator door apparatus will be described with reference to FIG. At the upper part of the elevator doorway, a hanger case 10 provided with a drive device for driving the elevator door 30 and the like is provided. The hanger case 10 is provided with a hanger rail 12 for guiding the movement of the elevator door 30 in addition to the driving device. On the hanger rail 12, there is provided a roller 22 that moves along the hanger rail 12 and moves left and right in the width direction of the elevator doorway. Such a roller 22 is coupled to a hanger plate 20 that is coupled to the elevator door 30. Through the above-described structure, the elevator door 30 can be connected to the hanger rail 12 of the hanger case 10 by the hanger plate 20 so as to be movable left and right.

  As described above, the upper part of the elevator door 30 is supported by the hanger case 10 via the hanger plate 20, and the lower part of the elevator door 30 is supported by the guide rail 40 via the door shoe 32, thereby The door 30 can stably move left and right in the width direction of the elevator doorway.

  However, since the conventional hanger plate 20 is manufactured by simply bending a flat metal plate having a small thickness, there is a problem that its rigidity is very weak. Accordingly, as shown in FIG. 9, if a constant force (F) acts on the elevator door 30 vertically, a certain portion of the hanger plate 20 bends (A and B in FIG. 9). The elevator door 30 may be detached from the guide rail 40.

  Accordingly, the present invention has been devised to solve the above-described problems, and the object of the present invention is to suppress the deformation of the hanger plate even when a certain force is applied to the elevator door. It is another object of the present invention to provide an elevator hanger plate and an elevator door device that can prevent the elevator door from being detached.

Here, the hanger plate is formed with a first embossing portion that protrudes forward or leans rearward in the vertical direction, and the first embossing portion extends in a width direction from a point corresponding to the center of the roller. It is formed so as to pass through the line.

  Since the elevator door device according to the present invention is configured to include the hanger plate in which the first embossing portion is formed, the hanger plate can be flexed upward even if a vertical force is applied to the elevator door. Can be suppressed. That is, since the first embossing portion is formed in the hanger plate in the vertical direction, the rigidity of the hanger plate that can prevent the hanger plate from being bent as described above can be secured, and accordingly, the hanger plate is perpendicular to the elevator door. Even if force is applied, the hanger plate does not bend upward, so that the elevator door can be prevented from being detached.

  Further, the prevention of such separation is more effective because the first embossing part is formed so as to pass through a line extending in the width direction from a point corresponding to the center of the roller. More specifically, when a force is applied to the hanger plate, deflection may first occur at a point where the hanger plate is connected to the roller, that is, a point corresponding to the center of the roller. However, in the hanger plate according to the present invention, the first embossing part is formed so as to pass through a line extending in the width direction from a point corresponding to the center of the roller, thus reinforcing the strength brittleness of the hanger plate. can do. Such a first embossing part may be formed in a pair of left and right with a connecting shaft connecting the hanger plate and the roller as a center.

  On the other hand, even if a force is applied to the elevator door at a point separated from the center line that bisects both ends in the width direction of the elevator door to the left and right, the elevator door device according to the present invention is It is possible to prevent the hanger plate from being twisted. That is, the hanger plate according to the present invention may be formed with a second embossing portion that protrudes forward or leans backward to prevent the hanger plate from twisting as described above. At this time, it is preferable that the second embossing part is formed so as to pass through a center line that bisects both ends in the width direction of the hanger plate.

  Further, the hanger plate may include a base plate and a connecting plate formed by being bent vertically from one end of the base plate, and the connecting plate is prevented from being folded to the base plate side. A third embossing part protruding inward may be formed in the connection part that connects the connection plates. Thereby, even if force is applied to the elevator door, the connecting portion can be prevented from bending upward.

  In addition, according to another preferred embodiment of the present invention, the elevator door device includes a hanger case provided on an upper part of the elevator doorway and provided with a hanger rail formed in the width direction of the elevator doorway. The roller that rolls on the hanger is connected to the hanger plate that moves left and right in the width direction of the elevator door in response to the roller rolling on the hanger rail, and is connected to the hanger plate. And an elevator door that opens and closes the doorway. Here, at both ends in the width direction of the hanger plate, a bent portion formed by being bent forward or backward from the hanger plate is provided, and the bent portion extends in a width direction from a point corresponding to the center of the roller. It is extended in the vertical direction so as to pass through the extended line.

  Furthermore, according to still another preferred embodiment of the present invention, the elevator hanger plate includes a hanger rail formed in the width direction of the elevator doorway, and includes a hanger case provided at an upper part of the elevator doorway, and the hanger rail. An elevator door that is guided and moves left and right in the width direction of the elevator doorway is connected via a roller that rolls on the hanger rail, and protrudes forward or leans backward, from a point corresponding to the center of the roller. A first embossing portion may be included that is formed in a vertical direction so as to pass a line extending in the width direction.

  Since the elevator hanger plate and the elevator door device according to the present invention include the hanger plate in which the first to third embossing portions are formed, the rigidity of the hanger plate can be increased, and the elevator door is constant. Even if this force is applied, it is possible to prevent the elevator door from being detached due to deformation of the hanger plate.

  Furthermore, the elevator hanger plate and the elevator door device according to the present invention do not require changing the material of the hanger plate material or increasing the thickness, and the hanger plate is used in a process such as welding a separate plate to increase rigidity. In spite of the fact that it is not necessary to connect to the hanger plate, it is possible to increase the rigidity of a part of the hanger plate or the entire hanger plate according to the target level easily and inexpensively.

  The structure of the hanger plate according to the present embodiment will be described in detail with reference to FIGS. 3 is a front view showing the hanger plate according to Embodiment 1, FIG. 4 is a plan view of FIG. 3, and FIG. 5 is a side view of FIG.

  As shown in FIGS. 3 to 5, the hanger plate 120 according to the first embodiment of the present invention may be formed with a first embossing part 124 that is folded backward in the vertical direction. At this time, the first embossing part 124 is preferably formed so as to pass a line (L) extending in the width direction from a point corresponding to the center of the roller. For reference, in this specification, the “longitudinal direction” means the longitudinal direction of the hanger plate 120, that is, the vertical direction in the hanger plate of FIG. 3, and the “lateral direction” or “width direction” means the hanger plate. The width direction of 120, that is, the lateral direction in the hanger plate of FIG.

  When a certain force is applied to the front or rear of the elevator door 130, a force applied to the hanger plate 120 coupled to the upper end of the door 130 from the lower end is applied to the front or rear. At this time, since the upper part of the hanger plate 120 is supported by the connecting shaft 123 provided at the center of the roller 122, when the force acts as described above, the hanger plate 120 is usually near the connecting shaft 123. Deflection occurs. Therefore, when a certain force is applied to the elevator door 130 due to carelessness or an accident of the elevator passenger, the hanger is generally along the line (L) connecting the centers of the rollers 122 connected to both sides of the upper part of the hanger plate 120. The bending of the plate 120 occurs.

  However, since the first embossing portion 124 is formed on the hanger plate 120 according to the present embodiment, the above-described bending can be suppressed to the maximum. That is, since the first embossing portion 124 is formed so as to pass through the line (L) extended in the width direction from the portion that is most easily bent on the hanger plate 120, that is, the point corresponding to the center of the roller 122. The elevator door device according to the embodiment can ensure the rigidity of the hanger plate 120 that can prevent the hanger plate 120 from being bent as described above. Accordingly, the elevator door device according to the present embodiment can prevent detachment of the elevator door 130 due to the bending of the hanger plate 120 to the maximum even when a certain force is applied to the elevator door 130.

  The first embossing part 124 can be formed by a method of pressing a part of the hanger plate 120 with a press or the like, and can be formed so as to protrude forward of the hanger plate 120 according to the manufacturing method, Can be formed to hesitate. In the present embodiment, the first embossing section 124 that is hung rearward is illustrated.

  On the other hand, since the deflection of the hanger plate 120 usually starts from both ends in the width direction of the hanger plate 120, when the first embossing portion 124 is formed near both ends of the hanger plate 120 than when formed near the center in the width direction. This is effective in preventing the hanger plate 120 from being bent. Therefore, it is preferable that the first embossing portions 124 are formed in a pair on the left and right sides around the connecting shaft 123 of the roller 122 connected near both ends of the hanger plate 120.

  In general, the deformation of the hanger plate 120 causes a problem when the hanger plate 120 is bent upward as described above. However, when a certain force is applied to the door 130 at a point separated from the center line that bisects both ends in the width direction of the elevator door 130 to the left and right, the hanger plate 120 is not bent as described above. Twisting can be a problem.

  In order to prevent such twisting, the second embossing part 125 may be formed on the hanger plate 120 according to the present embodiment. Similarly to the first embossing part 124, the second embossing part 125 can be formed by a method of pressing a part of the hanger plate 120 with a press or the like, and formed so as to protrude forward of the hanger plate 120 according to the manufacturing method. Or it can be formed to fold back. In the present embodiment, the second embossing section 125 that is hung rearward is illustrated.

  On the other hand, since both ends in the width direction of the hanger plate 120 are connected to the connecting shaft 123 of the roller 122 and the like, when force is applied to the hanger plate 120 at a position separated from the center in the width direction, the width of the hanger plate 120 is Generally, twisting occurs in the vicinity of the center line (C) that bisects both ends of the direction. Therefore, the second embossing part 125 is preferably formed so as to pass through a center line (C) that bisects both ends of the hanger plate 120 in the width direction.

  Further, since the hanger plate 120 starts twisting at both ends in the vertical direction of the hanger plate 120, the second embossing part 125 is formed near both ends in the vertical direction of the hanger plate 120 than when it is formed near the center in the vertical direction. This is effective for preventing the hanger plate 120 from twisting. Therefore, the second embossing part 125 is preferably formed near both ends of the hanger plate 120 in the vertical direction.

  Meanwhile, as shown in FIG. 5, the hanger plate 120 has a base plate 128 in which first and second embossing parts 124 and 125 are normally formed, and a connection formed by being bent vertically from one end of the base plate 128. And plate 129. Accordingly, the hanger plate 120 may have an “L” -shaped cross section when viewed from the side.

  When the hanger plate 120 is formed as described above, the connecting portion of the base plate 128 and the connecting plate 129 is very vulnerable to bending. Therefore, in order to compensate for the brittleness as described above, the third embossing portion 126 may be further formed on the hanger plate 120 according to the present embodiment.

  The third embossing part 126 is formed to protrude inward from a connection part that connects the base plate 128 and the connection plate 129. The hanger plate 120 according to the present embodiment can prevent the connecting portion from being bent upward by the third embossing portion 126 as described above.

  As described above, the elevator door device according to the present embodiment includes the hanger plate on which the first to third embossing portions are formed. Therefore, even if a certain force is applied to the elevator door, the hanger It is possible to prevent the elevator door from being detached due to the deformation of the plate.

  Furthermore, the elevator door apparatus according to the present embodiment does not require changing the material of the hanger plate material or increasing the thickness, and for increasing the rigidity, a separate plate is coupled to the hanger plate by a process such as welding. In spite of not having to be made, it is possible to increase the rigidity of a part of the hanger plate or the entire hanger plate according to the target level easily and inexpensively.
