[0011] The embodiments of the present disclosure will be described with reference to the accompanying drawings. In each drawing, the same or corresponding parts are designated by the same reference numerals. Duplicate descriptions of these parts will be appropriately simplified or omitted.

[0012] First Embodiment Fig. 1 is a diagram showing an overview of an elevator system to which a reinforcing member according to a first embodiment is applied.

[0013] In the elevator system 100 of Fig. 1 , a hoistway 101 passes through each floor of a building 102. A plurality of landings 103 are provided on each floor of the building 102. Each of the plurality of landings 103 faces the hoistway 101. At each landing 103, a person can enter and exit the hoistway 101 through a doorway 104. At each of the plurality of landings 103, a landing door 105 is provided at the doorway 104.

[0014] The car 106 is provided inside the hoistway 101. The car 106 is capable of moving up and down inside the hoistway 101. The car door 107 is provided on the side of the car 106 facing the landing door 105. The control device 108 can control the elevator system 100 as a whole.

[0015] Next, the landing door 105 will be described with reference to Fig. 2 and Fig. 3. Fig. 2 is a perspective view of the landing door to which the reinforcing member according to the first embodiment is applied. Fig. 3 is a perspective view of a main part of the landing door to which the reinforcing member according to the first embodiment is applied.

[0016] Fig. 2 shows the landing door 105 as seen from the hoistway 101 side. Fig. 3 shows a state in which the car 106 is stopped at the landing 103 and the door panel 110 and the car door 107 are open. The landing 103 is on the far side of the page in Fig. 3, and the car 106 is on the near side of the page. The landing door 105 includes the door panel 110, a threshold 111, and a hidden plate 112. The threshold 111 runs across the center of the page in Fig. 3.

[0017] The pair of door panels 110 are provided so as to be able to open and close so as to block the entranceway 104 in a closed state. The pair of door panels 110 are provided symmetrically on the left and right. Each of the pair of door panels 110 is movable in an opening and closing direction that is a direction perpendicular to the entranceway 104 and a horizontal direction. The back surface 110a of the door panel 110 faces the elevator shaft 101. The contact surface 110b of the door panel 110 faces the closing direction.

[0018] The threshold 111 is provided below the entrance / exit 104 so as to be continuous with the floor surface of the landing 103. At least a portion of the threshold 111 protrudes from the floor surface of the landing 103 toward the elevator shaft 101. The threshold 111 includes a groove portion 111a and a protrusion portion 111b.

[0019] The groove 111a is a groove provided along the opening and closing direction below the door panel 110. A door shoe of the door panel 110 (not shown) is restrained by the groove 111a, so that the door panel 110 moves to open and close along the groove 111a.

[0020] The protrusion 111b is a portion of the threshold 111 that protrudes further toward the elevator shaft 101 than the groove 111a. An end of the protrusion 111b approaches the car door 107 of the car 106. The protrusion 111b shields a gap that occurs between the landing 103 and the car 106 parked at the landing 103.

[0021] The concealing plate 112 is provided at the end of the rear surface 110a of the door panel 110 on the contact surface 110b side. The concealing plate 112 is provided from the top end to the bottom end of the door panel 110. That is, the concealing plate 112 is provided so as to extend vertically above the protrusion 111b. A gap is provided between the concealing plate 112 and the protrusion 111b. For example, the concealing plate 112 is made of resin so as not to interfere with the electromagnetic sensor.

[0022] When car 106 is stopped at landing 103 and landing door 105 and car door 107 are open, a gap is created between door panel 110 and car door 107, the distance of which is approximately the same as the length by which protrusion 111b protrudes toward hoistway 101. Hiding plate 112 shields the gap from the view of a person passing through entrance / exit 104. Hiding plate 112 can prevent problems such as objects falling through the gap or objects getting caught on back surface 110a of door panel 110.

[0023] Next, the hidden plate 112 will be described in more detail with reference to Figures 4 to 6. Figure 4 is a side view of the hidden plate to which the reinforcing members according to embodiment 1 are attached. Figure 5 is a cross-sectional view of the hidden plate to which the reinforcing members according to embodiment 1 are attached. Figure 6 is a view showing the main parts of the underside of the hidden plate to which the reinforcing members according to embodiment 1 are attached when attached.

[0024] 4 and 5 , the hidden plate 112 has a fixed side plate 113, a shielding plate 114, and a car side plate 115. The hidden plate 112 is generally U-shaped with the fixed side plate 113, the shielding plate 114, and the car side plate 115. For example, the fixed side plate 113, the shielding plate 114, and the car side plate 115 are molded integrally. For example, the area surrounded by the back surface 113s of the fixed side plate 113, the back surface 114s of the shielding plate 114, and the back surface 115s of the car side plate 115 becomes the back side 112a of the hidden plate 112.

[0025] The fixed side plate 113 is a plate that comes into contact with the back surface 110a of the door panel 110 (not shown in Figures 4 and 5) and is fixed to the door panel 110. The fixed side plate 113 is provided with a fixing hole 113a that is an elongated hole that is long in the longitudinal direction of the fixed side plate 113. The shielding plate 114 extends perpendicularly from the fixed side plate 113. The shielding plate 114 and the fixed side plate 113 are connected at a substantially right-angled corner 114a. The shielding plate 114 shields the gap between the door panel 110 and the car door 107. The car side plate 115 extends perpendicularly to the shielding plate 114 from the end of the shielding plate 114 opposite the fixed side plate 113.

[0026] FIG. 6 shows the lower portion of the concealing plate 112 as viewed from the back side 112a of the concealing plate 112. The fixed side plate 113 is fixed to the door panel 110 by threading the mounting bolt 116 through the fixing hole 113a into the door panel 110. The fixing hole 113a is located at a distance A from the shielding plate 114. The fixing hole 113a is located at a distance B from the lower end of the fixed side plate 113 in the longitudinal direction of the fixed side plate 113, i.e., the up-down direction when fixed. The position of the fixing hole 113a corresponds to the position of the screw hole in the door panel 110 into which the mounting bolt 116 is threaded. The position of the screw hole is common to many types of door panels 110. Therefore, a concealing plate 112 whose fixing hole 113a is determined by the distance A and the distance B can be applied to many types of door panels 110.

[0027] A trolley or other vehicle entering or exiting the car 106 may collide with the lower part of the concealing plate 112, particularly at the joint between the shielding plate 114 and the car side plate 115. Furthermore, if a vehicle or other component becomes caught in the gap between the concealing plate 112 and the protruding portion 111b and is then pulled out, a force opposite to that of the collision may be generated in the concealing plate 112. The force generated by the collision causes the shielding plate 114 to bend relative to the fixed side plate 113, with the corner 114a as a fulcrum. Because the concealing plate 112 is prone to collisions with a trolley or other component, and because the distance from the bottom end to the mounting bolt 116 is long, the deflection of the shielding plate 114 is large below the lowest fixing hole 113a. Because the concealing plate 112 is made of resin, the corner 114a below the fixing hole 113a is prone to cracking or other damage. Therefore, it is desirable to reinforce this portion of the concealing plate 112.

[0028] Next, a member for reinforcing the hidden plate 112 will be described with reference to Figs. 7 to 11. Fig. 7 is a perspective view of the reinforcing member according to the first embodiment in an attached state. Fig. 8 is a schematic diagram of the material plate from which the reinforcing member according to the first embodiment is made. Fig. 9 is a view of the reinforcing member according to the first embodiment after being bent. Fig. 10 is a view of the reinforcing member according to the first embodiment after being processed. Fig. 11 is a perspective view of a processing jig for processing the reinforcing member according to the first embodiment.

[0029] As shown in Figure 7, the reinforcing member 1 is attached to the back side 112a of the lower part of the hidden plate 112. For example, the reinforcing member 1 is manufactured by processing a single metal plate. For example, the reinforcing member 1 is made of an aluminum plate. The reinforcing member 1 has a first portion 2, a second portion 3, and a corner portion 4.

[0030] The first portion 2 is in direct or indirect contact with the rear surface 114s of the shielding plate 114. For example, the first portion 2 is attached to the shielding plate 114 with an adhesive member. In this case, the first portion 2 is in indirect contact with the rear surface 114s. In FIG. 7 , the lower end of the first portion 2 is located higher than the lower end of the shielding plate 114. Note that the lower end of the first portion 2 may be located at the same height as the lower end of the shielding plate 114.

[0031] The second portion 3 extends substantially perpendicularly from the first portion 2. That is, the second portion 3 and the first portion 2 are connected at the same angle as the angle between the fixed side plate 113 and the shielding plate 114. The second portion 3 and the first portion 2 are provided along the fixed side plate 113 and the shielding plate 114, respectively. The second portion 3 is provided with a first mounting hole 3a and a second mounting hole 3b, which are through-holes. In the example of FIG. 7 , a mounting bolt 116 is passed through the first mounting hole 3a. The second portion 3 is fixed to the door panel 110 together with the fixed side plate 113 by the mounting bolt 116. That is, the second portion 3 is fixed to the fixed side plate 113 by the mounting bolt 116. When fixed, the longitudinal direction of the second portion 3 faces the up-down direction. The second portion 3 may be further attached to the back surface 113s of the fixed side plate 113 with an adhesive member. In this case, the second part 3 does not need to be fixed by the mounting bolt 116 .

[0032] The corner 4 is the portion where the first portion 2 and the second portion 3 are joined. In this example, the corner 4 is the corner formed by the first portion 2 and the second portion 3. The corner 4 prevents the first portion 2 and the second portion 3 from moving relative to each other. The angle of the corner 4 is the same as the angle of the corner 114 a of the hidden plate 112.

[0033] The installation work of attaching the reinforcing member 1 to the already installed concealing plate 112 is carried out by an installation method including a transporting step, a processing step, and an installation step.

[0034] In the transportation step, a worker transports a metal plate, which will be the base of the reinforcing member 1 as shown in FIG. 8, to the work site. As an example, the thickness of the metal plate is 0.3 mm. The thickness of the metal plate may be any thickness that can be processed by the worker on site. Specifically, if the metal plate is an aluminum plate, the thickness may be 0.5 mm or less.

[0035] The metal plate is provided with a first mounting hole 3a and a second mounting hole 3b in advance. Specifically, the first mounting hole 3a and the second mounting hole 3b have the same diameter. The first mounting hole 3a is provided on one side of the center position C in the vertical direction, which is the longitudinal direction of the second portion 3. The second mounting hole 3b is provided on the other side opposite the center position C in the vertical direction. The first mounting hole 3a and the second mounting hole 3b are provided at positions symmetrical with respect to the center position C in the vertical direction. The position of the first mounting hole 3a will be described below as a representative example.

[0036] The distance L1 from the first mounting hole 3a to the other end of the second portion 3 is equal to or less than the distance B from the fixing hole 113a of the fixed side plate 113 (not shown in FIG. 8) to the lower end of the fixed side plate 113. Therefore, the lower end of the first portion 2 is located at the same height as or higher than the lower end of the shielding plate 114 (not shown in FIG. 8). The distance L2 from the first mounting hole 3a to the corner 4 is the same as the distance A from the fixing hole 113a in the hidden plate 112 to the corner 114a (shown in FIG. 8). Therefore, the first portion 2 comes into contact with the back surface 114s of the shielding plate 114.

[0037] Then, a processing step is performed. The processing step includes a bending step and an attaching step. As shown in FIG. 9 , in the bending step, a worker bends the metal plate at the corners 4 to form the first portion 2 and the second portion 3. In the subsequent attaching step, as shown in FIG. 10 , a worker attaches an adhesive member 5 to the first portion 2 and the second portion 3. For example, the adhesive member 5 is double-sided tape. Then, in the mounting step, a worker attaches the reinforcing member 1 to the concealing plate 112 as shown in FIG. 7 , and then fixes the second portion 3 with mounting bolts 116.

[0038] Note that bending a metal plate straight without marking it with scribe lines requires a highly skilled worker. On the other hand, it is desirable not to mark the metal plate with scribe lines in order to ensure the strength of the reinforcing member 1. Therefore, in the bending step of the processing process, as shown in FIG. 11 , the forming process from the metal plate to the reinforcing member 1 may be performed using a processing jig 10. The processing jig 10 is provided with two protrusions 11. The processing jig 10 also includes a reference surface 12, a processing surface 13, and corners 14. The processing jig 10 shown as an example in FIG. 11 has a rectangular parallelepiped shape.

[0039] The reference surface 12 is a surface that comes into contact with the second portion 3 during processing. The processed surface 13 is a surface that comes into contact with the first portion 2 during processing. The corner portion 14 connects the reference surface 12 and the processed surface 13 so that the angle between the reference surface 12 and the processed surface 13 is the same as the angle between the corner portion 4 of the reinforcing member 1.

[0040] Each of the two protrusions 11 has a radius equal to the inner diameter of the first mounting hole 3a. Each of the two protrusions 11 is provided on a reference surface 12. The distance between the two protrusions 11 is equal to the distance from the first mounting hole 3a to the second mounting hole 3b. The distance from the protrusion 11 to the corner 14 is equal to the distance L2 from the first mounting hole 3a to the corner 4.

[0041] When the reinforcing member 1 is processed, the first mounting hole 3a and the second mounting hole 3b of the metal plate as shown in Figure 7 are fitted onto two protrusions 11, respectively. At this time, the part corresponding to the second portion 3 contacts the reference surface 12. In this state, the part corresponding to the second portion 3 does not move relative to the processing jig 10.

[0042] Thereafter, the metal plate is bent using the corner 14 as a fulcrum until the portion corresponding to the first portion 2 contacts the processing surface 13. The corner 14 forms the same angle as the corner 4 of the reinforcing member 1. In this manner, the reinforcing member 1 is formed from the metal plate.

[0043] According to the first embodiment described above, the reinforcing member 1 includes a first portion 2 and a second portion 3. The reinforcing member 1 is attached to the concealing plate 112 by an attachment method. The attachment method includes a processing step and an attachment step. In the attached state, the second portion 3 is fixed to the fixed side plate 113. The first portion 2 directly or indirectly contacts the lower back surface 114s of the shielding plate 114. When an impact is applied to the shielding plate 114 in the direction from the front surface to the back surface 114s, the first portion 2 and the second portion 3 connected to the first portion 2 absorb the impact together with the shielding plate 114. The amount of deformation of the shielding plate 114 due to the impact is smaller than the amount of deformation when the reinforcing member 1 is not attached. Therefore, the reinforcing member 1 can suppress damage to the concealing plate 112.

[0044] In particular, when the first portion 2 and the second portion 3 are attached along the shielding plate 114 and the fixed side plate 113, respectively, a greater force can be received by the reinforcing member 1. As a result, damage to the concealing plate 112 can be more effectively suppressed.

[0045] Furthermore, the lower end of the first portion 2 is positioned at the same height as or higher than the lower end of the shielding plate 114. The lower the lower end of the first portion 2 is positioned, the greater the effect of suppressing damage to the shielding plate 114. On the other hand, if the lower end of the first portion 2 protrudes from the lower end of the shielding plate 114, the first portion 2 will hit the protruding portion 111b of the threshold 111, interfering with the opening and closing of the door panel 110. By positioning the lower end of the first portion 2 at the same height as or higher than the lower end of the shielding plate 114, the door panel 110 can be opened and closed without any hindrance.

[0046] The second portion 3 is provided with a mounting hole, which is a first mounting hole 3a or a second mounting hole 3b. The second portion 3 is fixed to the fixed side plate 113 by a mounting bolt 116 passed through the mounting hole. This prevents the reinforcing member 1 from coming off the hidden plate 112 and falling down the elevator shaft 101. Furthermore, the reinforcing member 1 can receive a greater force from the shielding plate 114.

[0047] The second portion 3 is provided with two mounting holes, a first mounting hole 3a and a second mounting hole 3b. The first mounting hole 3a and the second mounting hole 3b are located symmetrically with respect to the center position C. This allows the reinforcing member 1 to be applied to either of the two door panels 110 that swing open from both sides. As a result, workers do not need to prepare two types of reinforcing member 1, and installation work can be performed efficiently.

[0048] Furthermore, the first portion 2 and the second portion 3 are each made of a folded metal plate. This allows workers to easily transport the reinforcing member 1. Furthermore, the metal plate is an aluminum plate with a thickness of 0.5 mm or less. Because workers can fold the reinforcing member 1 at each work site, the reinforcing member 1 can be transported as a plate material. As a result, workers can transport the reinforcing member 1 even more easily.

[0049] Furthermore, first portion 2 is attached to rear surface 114s of shielding plate 114 by adhesive member 5. A force may be applied to shielding plate 114 in a direction from rear surface 114s to the front surface. In this case, first portion 2 balances the force together with shielding plate 114, thereby reducing the force acting on hidden plate 112 and reducing the amount of deformation of hidden plate 112. As a result, damage to hidden plate 112 can be suppressed even when subjected to a force in that direction.

[0050] Furthermore, in the bending process, the reinforcing member 1 is formed using the processing jig 10. Therefore, the worker can easily form the reinforcing member 1.

[0051] The reinforcing member 1 may be a member in which a first plate corresponding to the first portion 2 and a second plate corresponding to the second portion 3 are joined by a joining member corresponding to the corner portion 4. In this case, the first plate and the second plate are fixed by the joining member so that the distance between them does not change.

[0052] The processing jig 10 may be a member in which a reference plate having a surface corresponding to the reference surface 12 and a processing plate having a surface corresponding to the processing surface 13 are connected by a connecting member corresponding to the corner 14. For example, the connecting member that is the corner 14 may be a hinge that stops at the processing angle. The processing angle is the same angle as the corner 4 of the reinforcing member 1. In this case, the reference plate and the processing plate are movably connected by the connecting member so that the angle they form can be changed. Furthermore, the movement of the reference plate and the processing plate is stopped by the connecting member when the angle between the reference surface 12 and the processing surface 13 becomes the processing angle. Even in this case, the reinforcing member 1 can be formed by bending a metal plate set on the reference surface 12 to the processing angle while in contact with the processing surface 13.

[0053] The reinforcing member 1 may be processed without using the processing jig 10, for example, by bending it straight using the protruding portion 111b of the threshold 111.

[0054] Embodiment 2. Figures 12 and 13 are diagrams showing the main parts of a landing door to which a repair member according to embodiment 2 is applied. Figure 14 is a diagram showing a landing door to which a repair member according to embodiment 2 has been attached. Note that parts that are the same as or equivalent to parts according to embodiment 1 are given the same reference numerals. Explanation of these parts will be omitted.

[0055] The reinforcing member 1 shown in the first embodiment can also be used as a repair member 20 for a partially fractured hidden plate 112. The repair member 20 has the same configuration as the reinforcing member 1. FIGS. 12 and 13 show a partially fractured hidden plate 112. The fractured surface BS is the surface where the corner 114a between the fixed side plate 113 and the shielding plate 114 is fractured. When a force is applied to the lower part of the shielding plate 114, the shielding plate 114 bends from the state shown in FIG. 12 toward the back surface 114s as shown in FIG. 13. In this case, there is a risk that an object may get caught on the fractured surface BS, etc.

[0056] Generally, such breakage may frequently occur in each of the hidden plates 112 installed at the multiple landings 103. If all of the hidden plates 112 were to be replaced every time a breakage occurred, the replacement costs would be high.

[0057] 14, in the second embodiment, a repair member 20 is attached to the door panel 110 on the opposite side from that in the first embodiment. The repair member 20 is fixed to the fixed side plate 113 by the second mounting hole 3b instead of the first mounting hole 3a.

[0058] The first portion 2 is affixed to the shielding plate 114 by the adhesive member 5. In this state, the repair member 20 fixes the shielding plate 114 of the broken hidden plate 112 so that it does not move from its original position, i.e., repairs the hidden plate 112. Because the shielding plate 114 is fixed to its original position by the repair member 20, the fracture surface BS is not exposed. Even if an object becomes caught between the shielding plate 114 and the protruding portion 111b of the threshold 111 and is then pulled, generating a force in a direction from the back surface 114s of the shielding plate 114 to the front surface, the lower end of the shielding plate 114, which is attached to the first portion 2, will hardly bend in the closing direction.

[0059] In such repair work of the concealing plate 112, the repair member 20 is attached to the concealing plate 112 in the same manner as the attachment method in the first embodiment.

[0060] According to the second embodiment described above, the reinforcing member 1 is attached as the repair member 20 to the already broken concealing plate 112. The repair member 20 is attached using an attachment method. In the attached state, the second portion 3 is fixed to the fixed side plate 113. The first portion 2 directly or indirectly contacts the lower back surface 114s of the shielding plate 114. When an impact is applied to the shielding plate 114 in the direction from the front surface to the back surface 114s, the first portion 2 and the second portion 3 connected to the first portion 2 absorb the impact together with the shielding plate 114. This prevents the shielding plate 114 from being deformed, thereby preventing the fracture surface BS from being exposed. In this way, the repair member 20 can repair damage to the concealing plate 112.
