[0013] Figure 2 is an exploded perspective view showing the signage monitor device 11 according to the embodiment. Figure 3 is a perspective view showing the signage monitor device 11 according to the embodiment, illustrating a state where the signage monitor 12 is located at a working position.

[0014] As shown in Figures 2 and 3, the signage monitor device 11 includes the signage monitor 12, a mounting plate 13, and two left and right hooks 14 (Figure 2). The mounting plate 13 is fixed to the side wall 3 with screws or the like. The signage monitor 12 is superimposed on the mounting plate 13 on the +X direction side with respect to the mounting plate 13 and is attached to the mounting plate 13.

[0015] Figure 4 is a rear view showing the signage monitor 12 according to the embodiment. As shown in Figures 2 to 4, the signage monitor 12 includes a housing 21, a display unit 22 (Figures 2, 3), and a processing device 23 (Figure 4).

[0016] The housing 21 has a plurality of walls including, for example, a front wall 21a, a rear wall 21b, an upper wall 21c, a lower wall 21d, a left wall 21e, and a right wall 21f. The housing 21 is made of, for example, a metal material or a synthetic resin material.

[0017] Both the front wall 21a and the rear wall 21b extend in a direction orthogonal to the X direction (YZ plane) and are provided spaced apart from each other in the X direction.

[0018] The upper wall 21c and the lower wall 21d are spaced apart in the Z direction. The upper wall 21c and the lower wall 21d extend across the front wall 21a and the rear wall 21b.

[0019] The left wall 21e and the right wall 21f are spaced apart in the Y direction. The left wall 21e and the right wall 21f extend across the front wall 21a and the rear wall 21b.

[0020] Furthermore, the housing 21 has an upper end portion 21g and a lower end portion 21h. The upper end portion 21g and lower end portion 21h of the housing 21 are also the upper end portion 21g and lower end portion 21h of the signage monitor 12. The upper end portion 21g is an example of a first end portion. The lower end portion 21h is an example of a second end portion.

[0021] As shown in Figure 4, the rear wall 21b is provided with multiple hooks 21i, 21j, and 21k.

[0022] As an example, four hooking portions 21i are provided on the back wall 21b, one above, one below, one on each side. Holes 21m are provided in the hooking portions 21i. In other words, the portion of the back wall 21b surrounding the holes 21m is the hooking portion 21i. The holes 21m penetrate the back wall 21b in the X direction. The holes 21m have a region 21ma through which the head 26b of the projection 26 (described later) can pass, and a region 21mb extending upward from region 21ma, through which the head 26b cannot pass. That is, the holes 21m are what is known as "daruma holes".

[0023] As an example, two hooking portions 21j are provided on the upper end portion 21g. The two hooking portions 21j are spaced apart in the Y direction. Holes 21n are provided in the hooking portions 21j. In other words, the portion of the back wall 21b surrounding the hole 21n is the hooking portion 21j. The hole 21n penetrates the back wall 21b in the X direction. As an example, the shape of the opening of the hole 21n is a rectangle with the vertical direction as the longitudinal direction. A hook 14 is inserted into the hole 21n.

[0024] As an example, one hook portion 21k is provided. The hook portion 21k is located in the center of the rear wall 21b.

[0025] As shown in Figure 2, the display unit 22 is fixed to the housing 21 in a state where it is exposed from the front wall 21a. The display unit 22 is a display device capable of displaying various types of information. These types of information include advertisements. These types of information may also include information such as the operating status of elevator 1. The display unit 22 is, for example, a liquid crystal display, but is not limited to that.

[0026] As shown in Figure 4, the processing unit 23 is fixed to, for example, the rear wall 21b. The processing unit 23 controls the display of the display unit 22. The processing unit 23 is provided with a connection part 25 to which wiring 24 is connected. The wiring 24 is power lines, signal lines, etc.

[0027] As shown in Figure 1, the mounting plate 13 is located on the +X side, which intersects the vertical direction with respect to the side wall 3, and is fixed to the side wall 3.

[0028] Figure 5 is a front view showing the mounting plate 13 according to the embodiment. Figure 6 is a side view showing the hook 14 and projection provided on the mounting plate 13 according to the embodiment.

[0029] As shown in Figures 5 and 6, the mounting plate 13 is a rectangular plate whose thickness direction is aligned with the X direction. The mounting plate 13 is made of, for example, a metal material.

[0030] As shown in Figure 5, the mounting plate 13 is provided with a wiring hole 13a. The wiring hole 13a penetrates the mounting plate 13 in the X direction. The wiring hole 13a connects to a hole (not shown) provided in the side wall 3. Wiring 24 is passed through the wiring hole 13a and the hole in the side wall 3.

[0031] Furthermore, the front surface 13b of the mounting plate 13 is provided with a projection 26, a hook 14, and a hook portion 27.

[0032] As an example, four projections 26 are provided. The four projections 26 are provided on the front surface 13b, both vertically and horizontally. As shown in Figure 6, the projections 26 protrude from the front surface 13b in the +X direction. Each projection 26 has a shaft portion 26a and a head portion 26b. Each projection 26 is constructed, for example, by a stud bolt. The hook portion 21j of the signage monitor 12 is hooked onto the projection 26.

[0033] As an example, two hooks 14 are provided. The two hooks 14 are provided at the upper end of the mounting plate 13, spaced apart in the Y direction. The hooks 14 are made of, for example, a metal material.

[0034] As shown in Figure 6, the hook 14 protrudes from the mounting plate 13 in the +X direction. The hook 14 has a first portion 14a and a second portion 14b, and is formed in an L-shape when viewed from the side. The first portion 14a protrudes from the mounting plate 13 in the +X direction. The first portion 14a is provided with a concave portion 14c that opens upward. The concave portion 14c is, for example, a concave surface. The concave portion 14c forms a groove 14d (space). The hook portion 21j of the signage monitor 12 is hooked onto the concave portion 14c.

[0035] The second portion 14b protrudes upward from the first portion 14a. The upper end 14e of the second portion 14b is inclined with respect to the +X direction such that it slopes downward as it moves in the +X direction.

[0036] Furthermore, the hook 14 has a female threaded portion 14f. The female threaded portion 14f extends in the Y direction.

[0037] Figure 7 shows the rotation of the signage monitor 12 according to the embodiment. As shown in Figures 7(a) to (f), the concave portion 14c of the hook 14 supports the hook portion 21j of the signage monitor 12, enabling the signage monitor 12 to rotate in a direction that changes the distance between the mounting plate 13 and the lower end portion 21h of the signage monitor 12. In other words, the concave portion 14c supports the hook portion 21j of the signage monitor 12, enabling the signage monitor 12 to rotate in a direction that moves the lower end portion 21h of the signage monitor 12 away from the mounting plate 13 and in a direction that moves it closer to the mounting plate 13.

[0038] As shown in Figure 5, one hook portion 27 is provided as an example.

[0039] Figure 8 shows a wire member 31 according to an embodiment. As shown in Figures 3 and 8, the signage monitor device 11 further comprises a wire member 31. As shown in Figure 8, the wire member 31 has a wire 31a and two hooking parts 31b and 31c provided at both ends of the wire 31a. One hooking part 31b is hooked onto a hooking part 21k of the signage monitor 12. The other hooking part 31c is hooked onto a hooking part 27 of the mounting plate 13. The wire member 31 connects the mounting plate 13 and the signage monitor 12 and prevents the signage monitor 12 from falling.

[0040] Furthermore, as shown in Figure 4, the signage monitor device 11 has multiple (two as an example) male screw members 32. The male screw members 32 are inserted into holes 21p (Figures 2 and 3) provided in the left wall 21e and right wall 21f of the housing 21, and connect with the female screw portion 14f to fix the signage monitor 12, which is stacked on the mounting plate 13, to the hook 14.

[0041] Next, the installation method for the signage monitor device 11 will be explained. First, the worker fixes the mounting plate 13 to the side wall 3.

[0042] Next, the worker holds the signage monitor 12 at an angle (hereinafter also referred to as the tilted state) such that the lower end 21h of the signage monitor 12 is located in the +X direction relative to the upper end 21g. Next, the worker moves the signage monitor 12 toward the mounting plate 13, inserts the hook 14 into the hole 21n of the signage monitor 12, and hooks the hook portion 21j of the signage monitor 12 onto the concave portion 14c of the hook 14 (Figure 7(a)).

[0043] Next, the worker holds the signage monitor 12 in one hand to maintain its tilted position, and with the other hand connects the mounting plate 13 and the signage monitor 12 with the wire member 31. Then, the worker performs the wiring assembly work (wiring work) of the signage monitor 12 while it is still tilted. If there is any screw tightening work at this time, the work is performed while holding the signage monitor 12 in its tilted position.

[0044] Once the above work is completed, the worker rotates the signage monitor 12 using the concave portion 14c of the hook 14 as a pivot point so that the lower end 21h of the signage monitor 12 moves in the -X direction, and places the signage monitor 12 on the mounting plate 13 (Figures 7(a) to (f)).

[0045] Next, the worker moves the signage monitor 12 upward by a predetermined distance so that the area 21ma of the hole 21m in the back wall 21b aligns with the head 26b of the projection 26 of the mounting plate 13 in the X direction, and then moves the signage monitor 12 in the -X direction so that the head 26b of the projection 26 fits into the area 21ma of the hole 21m. Next, the worker moves the signage monitor 12 downward so that the shaft 26a of the projection 26 fits into the area 21mb of the hole 21n. As a result, the hook portion 21i of the signage monitor 12 catches on the projection 26 and is prevented from coming off by the head 26b of the projection 26.

[0046] Next, the worker connects the male screw member 32 to the female screw portion 14f of the hook 14, thereby fixing the signage monitor 12, which is stacked on the mounting plate 13, to the hook 14.

[0047] As described above, the signage monitor device 11 of this embodiment comprises a mounting plate 13, a signage monitor 12, and a hook 14. The mounting plate 13 is located on the side of the side wall 3 (object to be fixed) in the +X direction (first direction) which intersects the vertical direction, and is fixed to the side wall 3. The signage monitor 12 has an upper end portion 21g (first end portion) provided with a hook portion 21j, and a lower end portion 21h (second end portion) opposite to the upper end portion 21g, and is attached to the mounting plate 13 by overlapping it with the mounting plate 13 on the +X direction side. The hook 14 protrudes from the mounting plate 13 in the +X direction. The hook 14 has a first portion 14a, a second portion 14b, and a concave portion 14c. The first portion 14a protrudes from the mounting plate 13 in the +X direction. The second portion 14b protrudes upward from the first portion 14a. The concave portion 14c is provided in the first portion 14a, opens upward, and supports the hook portion 21j, enabling the signage monitor 12 to rotate in a direction that changes the distance between the mounting plate 13 and the lower end portion 21h.

[0048] With this configuration, a worker can tilt the signage monitor 12 so that its lower end 21h is positioned in the +X direction relative to its upper end 21g, and then hook the hanging portion 21j of the signage monitor 12 onto the concave portion 14c of the hook 14, while performing wiring work on the signage monitor 12. At this time, the worker can support the signage monitor 12 with one hand and perform wiring work with the other. Therefore, the installation of the signage monitor 12 is made easier. In addition, since the weight of the signage monitor 12 that the worker has to support is reduced, worker fatigue is reduced and work efficiency is improved. Furthermore, since the hanging portion 21j of the signage monitor 12 is supported by the concave portion 14c of the hook 14, it is difficult for the hanging portion 21j to come off the hook 14. Therefore, the signage monitor 12 can be prevented from falling, making it safer.

[0049] Here, for example, the signage monitor 12 is installed at a height that a person would have to look up at from below. Therefore, if, for example, a hook 14 is provided at the lower end 21h, the upper end 21g side of the signage monitor 12 will be opened, and the signage monitor 12 will get in the way of the worker's work, making it difficult to see the position of the wiring 24 and thus making the work difficult.

[0050] In contrast, in this embodiment, the first end is the upper end 21g, and the second end is the lower end 21h. That is, the hook 14 is provided on the upper end 21g.

[0051] With this configuration, the lower end 21h side of the signage monitor 12 is opened, making it less likely for the signage monitor 12 to get in the way of the worker's work, and the position of the wiring 24 is easily visible, making the work easier.

[0052] Furthermore, the upper end portion 21g of the second portion 14b is inclined with respect to the +X direction such that it slopes downward as it moves in the +X direction. The hook portion 21j is provided with a hole 21n into which the hook 14 is inserted.

[0053] With this configuration, the upper end portion 21g of the second portion 14b is inclined downward as it moves away from the mounting plate 13, making it easier to insert the hook 14 into the hole when the signage monitor 12 is tilted so that the lower end portion 21h of the signage monitor 12 is positioned in the +X direction relative to the upper end portion 21g.

[0054] Furthermore, the signage monitor device 11 is equipped with a male screw member 32. The hook 14 has a female screw portion 14f. The male screw member 32 connects with the female screw portion 14f to fix the signage monitor 12, which is superimposed on the mounting plate 13, to the hook 14.

[0055] With this configuration, the signage monitor 12 can be fixed to the hook 14.

[0056] Furthermore, the signage monitor device 11 includes a wire member 31 that connects the mounting plate 13 and the signage monitor 12, preventing the signage monitor 12 from falling.

[0057] With this configuration, even if the signage monitor 12 becomes detached from the hook 14, the fall of the signage monitor 12 can be prevented.

[0058] In addition, this embodiment provides two hooks 14, one on the left and one on the right.

[0059] With this configuration, the signage monitor 12 is stably supported by the hook 14.

[0060] In the above embodiment, an example was shown in which the signage monitor device 11 is attached to the side wall 3 of the elevator car 2, but this is not the only example. For example, the signage monitor device 11 may be attached to the wall of the elevator landing of the building where the elevator 1 is installed, or to a stand installed in the landing. The landing wall and stand are just examples of objects to which the device can be fixed.

[0061] 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 carried out 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 of the invention and its equivalents. [Explanation of Symbols]
