[0010] The adapter plate for the elevator landing control panel and the mounting structure for the elevator landing control panel in an embodiment of the present invention will be described below with reference to the drawings. First, the elevator landing according to this embodiment will be described using Figure 1.

[0011] As shown in Figure 1, in this embodiment, a three-sided frame 2 is installed at the elevator landing 1, and a landing door 3 is installed inside the three-sided frame 2. A landing control panel 4 is fixed near the three-sided frame 2. The landing control panel 4 is configured for users to register calls to summon the elevator car, and is also referred to as an HIB (Integrated Hub).

[0012] Next, the mounting structure for the landing control panel according to this embodiment (hereinafter simply referred to as mounting structure 10) will be described with reference to Figures 2 and 3. Mounting structure 10 is a structure for attaching the landing control panel 4 shown in Figure 1 to the wall surface 5 of the landing 1.

[0013] As shown in Figures 2 and 3, the mounting structure 10 includes a box 20, a plurality of brackets 30, 40, an adapter plate 50, and a connecting member 60.

[0014] The box 20 is located within the wall opening 6 formed in the wall surface 5. The box 20 is formed in a box shape by sheet metal processing. Although not shown, the box 20 is fixed to the wall of the boarding area 1.

[0015] Each of the brackets 30, 40 is located within the wall opening 6. The brackets 30, 40 are attached to the box 20 using bolts B1, B2, etc. Each of the brackets 30, 40 may be manufactured by sheet metal processing. In the present embodiment, two brackets 30, 40 are attached to the box 20. The bracket located above is referred to as the first bracket 30, and the bracket located below is referred to as the second bracket 40, and will be described below.

[0016] The first bracket 30 may include a first attachment portion 31 for attaching the first bracket 30 to the box 20, and a first attachment-receiving portion 32 for attaching the adapter plate 50. The first attachment portion 31 may be located at the upper part of the first bracket 30, and the first attachment-receiving portion 32 may be located at the lower part of the first bracket 30.

[0017] The first attachment portion 31 is fixed to a bolt B1 fixed to the upper part of the box 20 using a nut N1, etc. A first bolt through-hole 33 through which the bolt B1 passes is formed in the first attachment portion 31. The first bolt through-hole 33 is formed in an elongated shape along the depth direction of the wall opening 6 and may be notched at the front.

[0018] The first attachment-receiving portion 32 is located within the wall opening 6 but is disposed on the extension of the wall surface 5. The position of the first bracket 30 may be adjusted so that the first attachment-receiving portion 32 is disposed on the extension of the wall surface 5 by the above-described first bolt through-hole 33. A plurality of nuts N3 may be welded to the back surface of the first attachment-receiving portion 32.

[0019] The second bracket 40 may include a second mounting portion 41 for attaching the second bracket 40 to the box 20 and a second mounting portion 42 for attaching the adapter plate 50. The second bracket 40 may be formed in an L-shape. In this case, the second mounting portion 41 is the portion extending horizontally, and the second mounting portion 42 is the portion extending vertically.

[0020] The second mounting portion 41 is fixed to a bolt B2 fixed to the lower part of the box 20 using a nut N2 or the like. A second bolt penetration portion 43 may be formed in the second mounting portion 41 through which the bolt B2 passes. The second bolt penetration portion 43 may be formed in an elongated shape along the depth direction of the wall opening 6.

[0021] The second mounting portion 42 is located within the wall opening 6, but is positioned on the extension of the wall surface 5. The position of the second bracket 40 may be adjusted using the second bolt penetration portion 43 described above so that the second mounting portion 42 is positioned on the extension of the wall surface 5.

[0022] The adapter plate 50 is configured to be attached to brackets 30 and 40 installed in wall openings 6 formed in the wall surface 5 of the elevator landing 1. As shown in Figure 3, the adapter plate 50 includes a plate body 51, a plurality of bolt holes 52, and an injection port 53.

[0023] The plate body 51 covers the wall opening 6 and overlaps the wall surface 5 near the wall opening 6. The plate body 51 may be formed in a flat plate shape. The plate body 51 is formed to protrude outwards from the wall opening 6.

[0024] In this embodiment, as shown in Figure 2, the plate body 51 extends upward and downward from the wall opening 6, forming a rectangular shape with the vertical direction as its longitudinal direction. For example, in a newly installed landing control panel 4 (see Figure 2), if buttons for wheelchair users that were not provided in the existing landing control panel are added, the plate body 51 extends relatively far downward from the wall opening 6. The mounting structure according to this embodiment is intended for cases where the landing control panel 4 is modified to such a new installation.

[0025] However, the direction in which the plate body 51 protrudes significantly from the wall opening 6 is arbitrary. In any direction, the joining member 60 should be placed in the portion that protrudes relatively significantly, and the injection port 53 should be placed in a position that overlaps with the joining member 60.

[0026] As shown in Figure 3, the bolt holes 52 are configured to attach the adapter plate 50 to the brackets 30 and 40. In this embodiment, the plate body 51 has three bolt holes 52. Two of these bolt holes 52 are for attaching the adapter plate 50 to the first mounting portion 32 of the first bracket 30 with bolts B3, and the remaining bolt hole 52 is for attaching the adapter plate 50 to the second mounting portion 42 of the second bracket 40 with bolts B4. The type of bolt B3 for attaching to the first mounting portion 32 and the type of bolt B4 for attaching to the second mounting portion 42 are arbitrary as long as interference with the internal components of the landing control panel 4 attached to the adapter plate 50 is avoided.

[0027] As shown in Figures 4(a) and 4(b), the inlet 53 is formed in the portion of the plate body 51 that overlaps with the wall surface 5. The inlet 53 is configured to penetrate the plate body 51 and inject a solvent 70 that causes the joining member 60 for joining the plate body 51 to the wall surface 5 to lose its ability to join. In this embodiment, when the adapter plate 50 is attached to the brackets 30 and 40, the inlet 53 is located below the wall opening 6 in the plate body 51.

[0028] The injection port 53 may be formed in any planar shape, as long as it is possible to inject the solvent 70 and cause the bonding properties of the joining member 60 to be lost. For example, as shown in Figure 4(a), the injection port 53 may be formed in a straight line. The injection port 53 may be an elongated hole that extends along the horizontal direction and has the horizontal direction as its longitudinal direction.

[0029] A bolt B5 for attaching the landing control panel 4 may be fixed to the plate body 51. In the examples shown in Figures 4(a) and 4(b), the bolt B5 is positioned to overlap with the connecting member 60, but the position of the bolt B5 is arbitrary as long as the landing control panel 4 can be attached.

[0030] As shown in Figures 3 and 4, the joining member 60 is located on the portion of the plate body 51 that overlaps with the wall surface 5. The joining member 60 is interposed between the wall surface 5 and the plate body 51. The joining member 60 may be made of adhesive. In this case, the adhesive is applied to the back surface of the plate body 51, and the adapter plate 50 is brought into contact with the wall surface 5. After that, the adhesive hardens to form an adhesive layer. Alternatively, the joining member 60 may be made of adhesive. In this case, an adhesive sheet made of adhesive is attached to the back surface of the plate body 51. After the adapter plate 50 is brought into contact with the wall surface 5, the adhesive sheet joins the plate body 51 and the wall surface 5.

[0031] The joining member 60 can be made of any material that can join the adapter plate 50 to the wall surface 5, regardless of whether it is made of an adhesive or a tack, and that can lose its bonding properties (adhesion or tackiness) when used with the solvent 70. The solvent 70 is a material that can suitably lose its bonding properties depending on the type of joining member 60. For example, if the joining member 60 is made of an acrylic adhesive, known solvents such as a solvent containing methyl ethyl ketone or a solvent containing 1-bromopropane may be used as the solvent 70. For example, if the joining member 60 is made of an adhesive sheet, a seal remover containing isopropyl alcohol or other known solvents may be used as the solvent 70. Even if the joining member 60 is made of other materials, known solvents can be used as the solvent 70.

[0032] Next, a method for attaching the mounting structure 10 according to this embodiment, which has the configuration described above, to the wall surface 5 of the landing 1 will be explained. Here, the explanation will be given as an example of modifying an existing landing control panel (not shown) to a new landing control panel 4.

[0033] First, as shown in Figure 5, the existing landing control panel is removed, along with the existing adapter plate and bracket (neither of which are shown). In this case, as shown in Figure 5, the box 20 remains attached to the wall opening 6.

[0034] Next, as shown in Figure 6, the first bracket 30 and the second bracket 40 are attached to the box 20. In this case, the first mounting portion 31 of the first bracket 30 is fixed to the upper bolt B1 of the box 20 using a nut N1 or the like. The second mounting portion 41 of the second bracket 40 is fixed to the lower bolt B2 of the box 20 using a nut N2 or the like.

[0035] Next, as shown in Figure 7, the adapter plate 50 is attached to the first bracket 30 and the second bracket 40. In this case, bolts B3 are inserted into the two bolt holes 52 of the adapter plate 50 and fastened using nuts N3 welded to the first mounting portion 32 of the first bracket 30. A bolt B4 is inserted into the remaining bolt hole 52 of the adapter plate 50 and fastened using a nut N4 or the like to the second mounting portion 42 of the second bracket 40. The portion of the adapter plate 50 located above and below the wall opening 6 abuts against the wall surface 5.

[0036] Before attaching the adapter plate 50 to the brackets 30 and 40, a connecting member 60 is pre-attached to the plate body 51 of the adapter plate 50. The connecting member 60 is attached to the back surface (the side facing the wall 5) of the plate body 51 so as to overlap with the injection port 53. If the connecting member 60 is made of adhesive, the adhesive is applied to the back surface of the plate body 51. If the connecting member 60 is made of adhesive material, an adhesive sheet or the like is attached to the back surface of the plate body 51. When the adapter plate 50 is attached to the brackets 30 and 40, the connecting member 60 is interposed between the plate body 51 and the wall 5, allowing the plate body 51 to be joined to the wall 5.

[0037] After attaching the adapter plate 50 to the brackets 30 and 40, the newly installed landing control panel 4 is attached to the adapter plate 50, as shown in Figure 2.

[0038] In this way, the renovation work on the platform control panel is completed.

[0039] If the newly installed landing control panel 4 is to be further modified, the adapter plate 50 is removed from the wall surface 5 after the landing control panel 4 is removed. In this case, solvent 70 is injected into the inlet 53 of the adapter plate 50. As a result, the solvent 70 spreads to the joining member 60, causing the joining ability of the joining member 60 to be lost. Therefore, the plate body 51 can be removed from the wall surface 5. The adapter plate 50 can be removed from the wall surface 5 by removing the bolts B3 and B4 mentioned above. As mentioned above, the solvent 70 is appropriately selected according to the type of joining member 60. Figure 4(b) shows the process of bringing a container 71 containing solvent 70 close to the inlet 53 in order to inject the solvent 70 into the inlet 53.

[0040] As described above, according to this embodiment, an injection port 53 is formed in the portion of the plate body 51 of the adapter plate 50 that overlaps with the wall surface 5. The injection port 53 is configured to penetrate the plate body 51 and inject a solvent 70 that causes the joining member 60 for joining the plate body 51 to the wall surface 5 to lose its ability to connect. As a result, when the solvent 70 is injected into the injection port 53, the solvent 70 can be spread to the joining member 60 that joins the plate body 51 to the wall surface 5, causing at least a portion of the joining member 60 to lose its ability to connect. Therefore, the adapter plate 50 can be easily removed from the wall surface 5, and damage such as scratches or stains can be prevented from remaining on the wall surface 5. In addition, since the plate body 51 is not fixed to the wall surface 5 with bolts, bolt holes can be avoided from remaining on the wall surface 5. As a result, the adapter plate 50 can be easily removed and damage to the wall surface 5 after removal can be reduced.

[0041] Furthermore, according to this embodiment, the inlet 53 is formed in a straight line. This allows the solvent 70 to spread evenly in the direction in which the inlet 53 extends in a straight line. As a result, the bonding properties of the joining member 60 can be efficiently lost, and the adapter plate 50 can be removed from the wall surface 5 even more easily.

[0042] In the embodiment described above, an example was described in which the inlet 53 of the adapter plate 50 is formed in a straight line. However, this embodiment is not limited to this. For example, as shown in Figure 8, the inlet 53 may be formed in a zigzag shape. In this case, the solvent 70 can be spread over a wider area of ​​the joining member 60. As a result, the joining member 60 can lose its bonding ability over a wider area, and the adapter plate 50 can be removed from the wall surface 5 more easily.

[0043] Furthermore, in the above-described embodiment, an example was described in which the adapter plate 50 is attached to the second mounting portion 42 of the second bracket 40 using bolts B4 or the like. However, this embodiment is not limited to this. For example, as shown in Figures 9(a) and 9(b), a bracket through-hole 54 through which the second bracket 40 passes may be formed in the plate body 51. The second bracket 40 shown in Figures 9(a) and 9(b) may include a second mounting portion 41 and an engaging portion 44. The second bracket 40 is formed in an L-shape, and the engaging portion 44 is the portion of the second bracket 40 that extends in the vertical direction. As shown in Figure 9(a), two engaging portions 44 may be formed, but the number of engaging portions 44 is arbitrary.

[0044] In the example shown in Figures 9(a) and 9(b), the second bracket 40 is inserted into the bracket through-hole 54 of the adapter plate 50 before being fixed to the box 20. With the adapter plate 50 in this state, it is attached to the first bracket 30. Then the second bracket 40 is fixed to the box 20. At this time, the bolt B2 can be fastened through the opening 55 formed in the plate body 51. The second bracket 40 is fixed in a position where the engaging portion 44 abuts against the surface of the plate body 51 (the surface opposite to the wall surface 5). The engaging portion 44 may also press against the surface of the plate body 51.

[0045] In this way, the second bracket 40 can support the adapter plate 50. This means that if the joining member 60 is made of adhesive, the adapter plate 50 can be supported by the second bracket 40 until the adhesive hardens, preventing the adapter plate 50 from shifting. Also, when pressing the adapter plate 50 against the wall surface 5, the joining force of the joining member 60 can be increased.

[0046] Furthermore, in the embodiment described above, as shown in Figure 10, a screw hole 56 may be formed in the portion of the plate body 51 that overlaps with the wall surface 5. This allows a force to be applied to the plate body 51 in a direction that pulls it away from the wall surface 5 by screwing a bolt B6 into the screw hole 56 and rotating it. As a result, the adapter plate 50 can be easily removed from the wall surface 5.

[0047] According to the embodiments described above, easy removal is possible, and damage to the wall surface after removal can be reduced.

[0048] While several embodiments of the present invention have been described, these embodiments are presented as examples only and are not intended to limit the scope of the invention. These novel embodiments can be implemented in a variety of other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their variations are included in the scope and spirit of the invention, as well as in the claims and their equivalents. [Explanation of symbols]
