Description

[Technical Field]

[0001] The present invention relates to a hinge mounting structure in which a pair of plates are rotatably connected to each other by a shaft. [Background technology]

[0002] Hinges have been used in various fields to connect one attachment object, such as a door or a lid, to another attachment object, such as a main body, so that the door can be opened and closed (rotated). For example, in the traffic light controller described in Patent Document 1, a hinge was used to openably and closably attach an inner door to the inside of the opening of the housing. Generally, this type of hinge has a pair of plates that open and close with an axis between them, as described in Patent Document 2, for example. In the traffic light controller, one plate is fixed to the inner door and the other plate is fixed to the housing, so that the inner door can be opened and closed relative to the housing.

[0003] When assembling such a traffic signal controller, as shown in Figures 3(a) to (c), when fixing the hinge 10 to the inner door 120 with screws, first, one plate 20 to be fixed is positioned on the mounting surface of the inner door 120, which is placed in a substantially horizontal position. At this time, the plate 20 positioned on the mounting surface is misaligned with the center of gravity (axis) of the entire hinge 10, and the center of gravity (axis) of the entire hinge 10 is located outside the mounting surface. Therefore, when the hinge 10 is released from its position, the rotational moment due to its own weight causes the hinge 10 to trace a rotational trajectory indicated by the dashed arrow in Figure 3(c), and it comes off the mounting surface and falls.

[0004] Therefore, when fastening the hinge 10 to the inner door 120 with screws, it was necessary to hold the hinge 10 down on the mounting surface with one hand to prevent it from falling while fastening the screws. This type of screwing operation required the following 11 steps in detail. That is, as shown in Figure 14(a), 1. Remove the hinge, 2. Position it on the inner door, 3. Hold the hinge with your left hand and remove the screw with your right hand, 4. Pass the screw to your left hand, 5. Take the screwdriver with your right hand, 6. Insert the left-hand screw into the bit, 7. Insert the screw into the screw hole in the inner door, 8. Screw in the first screw, 9. Remove the screw, 10. Insert the screw into the bit and insert it into the screw hole, and 11. Screw in the second screw. This series of steps had to be performed for both the top and bottom hinges.

[0005] In particular, a tedious step in screwing the hinge 10 is to hold down the hinge 10 to prevent it from falling, but it is possible to use a special jig, as shown in Figure 14(b), for example. That is, if a jig is prepared in advance, and the center of gravity (axis) of the entire hinge 10 is supported by the jig when the hinge 10 is fixed to the inner door 120 with screws, the hinge 10 does not need to be held down by hand.

[0007] As mentioned above, when assembling a traffic light controller, when fixing the hinge to the inner door with screws, the hinge must be held down by hand to prevent it from falling, which is troublesome, time-consuming, and costly. This problem is not limited to the assembling of traffic light controllers, but applies widely to any case where one plate of a hinge is fixed to an object to be attached.

[0008] It is also possible to use a special jig as shown in Figure 14(b), but this would incur additional costs for the jig itself.Moreover, not only would the jig need to be stored and prepared, but setting the jig when screwing would be a hassle, which would again take time and increase costs.

[0009] The present invention was made in response to the above-mentioned problems of the conventional technology, and aims to provide a hinge mounting structure that makes it possible to support the hinge directly below its center of gravity without using a jig when mounting the hinge, prevents the hinge from shifting position even when the operator lets go of the hinge, and improves the efficiency of the mounting work and reduces costs. [Means for solving the problem]

[0010] In order to achieve the above-mentioned object, one aspect of the present invention is to provide a method for manufacturing a semiconductor device comprising: A hinge mounting structure in which a pair of plates are rotatably connected to each other by a shaft, When one plate of the hinge is placed and fixed on a substantially horizontal mounting surface of an object to be attached, a support part is provided on the object to be attached that supports the entire hinge directly below the center of gravity located outside the mounting surface to prevent it from falling. [Effects of the Invention]

[0011] According to the hinge mounting structure of the present invention, when mounting the hinge, the hinge is supported directly below its center of gravity without using a jig, so that the hinge does not shift position even if the hinge is released, thereby improving the efficiency of the mounting work and reducing costs.

DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, a representative embodiment of the present invention will be described with reference to the drawings. 1 to 14 show one embodiment of the present invention. The mounting structure of the hinge 10 according to this embodiment is a structure for mounting one mounting object to another mounting object via the hinge 10 in an openable and closable manner, and will be described below using as an example a case where the structure is applied to the housing 101 and inner door 120 of a traffic light controller 100. Here, the inner door 120 corresponds to an example of the "one mounting object" of the present invention, and the housing 101 corresponds to an example of the "other mounting object" of the present invention. Note that the components, shapes, numerical values, etc. shown in the embodiment described below are all examples of the present invention and are not intended to limit the present invention.

[0014] <Outline of the signal controller 100> First, an overview of a traffic light controller 100 to which the mounting structure of the hinge 10 of the present invention is applied will be described. As shown in Fig. 13, a traffic light 1 according to this embodiment includes, for example, a traffic light 2 for vehicles and a traffic light 3 for pedestrians, and a traffic light controller 100 that controls the lighting of these traffic lights 2 and 3. The traffic lights 2 and 3 are each mounted on a support pole 4 at a height that makes them easily visible to pedestrians and drivers. Meanwhile, the traffic light controller 100 is mounted on the support pole 4 near the ground where it is easy to work with.

[0015] As shown in Figures 8, 9, and 12, the signal controller 100 includes a housing 101 formed in the shape of a vertically long rectangular parallelepiped box, and stores a control unit 130 that performs various controls such as turning on and off the signal lamps 2 and 3, a manual operation unit 115, and related components such as a power supply unit inside the housing 101. The housing 101, which forms the main part, is formed of a metal plate such as sheet metal, and has a large opening on the front side. An outer door 110 that covers the opening is provided on the front side of the housing 101 in an openable and closable manner, and an inner door 120 is also provided inside the outer door 110 in an openable and closable manner.

[0016] The outer door 110 is formed from a metal plate such as sheet metal into a vertically long rectangular plate that matches the periphery of the opening of the housing 101. One side end of the outer door 110 is connected to one side end of the periphery of the opening of the housing 101 via a pair of upper and lower hinges 111, and the other side end can be opened forward by the hinges 111. Here, the hinges 111 are removable hinges in which the shaft cylinder of one plate fixed to the outer door 110 can be inserted and removed in the vertical direction relative to the rotation shaft of one plate fixed to the housing 101, allowing the outer door 110 to be easily removed, but since its configuration and installation are common, detailed description will be omitted. The outer door 110 is provided with a locking unit 112 that allows it to be locked to the housing 101.

[0017] Furthermore, an opening window (not shown) is provided at a predetermined position on the lower half side of the outer door 110, and this opening window is covered by a sub-door 113 provided on the outer wall of the outer door 110, as shown in Fig. 8. The sub-door 113 can also be opened and closed by well-known hinges (not shown), and is also provided with a locking unit 114 so that it can be locked relative to the outer door 110. As shown in Fig. 9, a manual operation unit 115 is attached to the inside of the opening window of the outer door 110.

[0018] The manual operation unit 115 is used to manually operate the signal lights 2 and 3 instead of automatically controlling them. The manual operation unit 115 is configured so that it can be operated from the outside through the opening window when the sub-door 113 is open, even when the outer door 110 is closed. For example, at an event, a user (such as a police officer) can open the sub-door 113 and manually operate the operation button in the manual operation unit 115 to switch the lighting of the signal lights 2 and 3 on and off as desired.

[0019] As shown in Figures 9 and 12, inner door 120 is formed, for example, by integral molding of synthetic resin into a vertically long rectangular panel of a size that fits inside the front opening of housing 101. One side end of inner door 120 is connected to one side end of the periphery of the opening of housing 101 via a pair of upper and lower hinges 10, and the other side end can be opened forward by hinges 10, similar to the outer door 110. Here, hinge 10 forms the mounting structure of hinge 10 of the present invention, and will be described in detail later. Note that Figure 12 shows the inside of inner door 120 in housing 101 as empty, but in reality, related parts and the like (not shown) are stored therein.

[0020] As shown in Fig. 9, the control unit 130 is disposed, for example, on the upper half side of the inner door 120, and basically controls the lighting or flashing times of the multiple signal lights 2, 3. The control unit 130 has an operation panel 131 on its front, and a user can operate the operation panel 131 to set or appropriately change the lighting or flashing times and lighting sequence of the signal lights 2, 3. In addition to these basic functions, the control unit 130 may also have a lighting brightness adjustment function and a communication function that enables communication with a computer at a traffic control center.

[0021] <About Hinge 10> Next, the hinge 10 used in the signal controller 100 will be described. The relative dimensional relationships and shapes of the components including the hinge 10 shown in the drawings are subject to appropriate design changes and may differ from the actual ones. Furthermore, terms expressing directions such as front, back, left, right, and up and down relative to the hinge 10 are defined for the sake of convenience in explaining the positional relationships of the components, and the hinge 10 is not, of course, limited to such directions.

[0022] As shown in Fig. 9, the hinge 10 is used to connect an inner door 120, which opens and closes inside the housing 101 of a traffic light controller 100, to the housing 101 so that the door 120 can rotate horizontally. As shown in Figs. 4 to 7, the hinge 10 is formed by connecting a pair of plates 20, 30 to each other so that the plates can open and close with each other via a shaft 11. Here, the shaft 11 is pin-shaped, and the shaft 11 is inserted into shaft tubes 21, 31 called knuckles that are formed along the opposing end edges of the plates 20, 30 so as to interlock with each other in a staggered manner.

[0023] Each of the plates 20, 30 is made of a blade-shaped metal plate, but one plate 20 (hereinafter referred to as the first plate 20) that is attached to the inner door 120 (one attachment object) is formed in a long, narrow rectangle, and the other plate 30 (hereinafter referred to as the second plate 30) that is attached to the housing 101 (another attachment object) is formed in an angle shape with a substantially L-shaped cross section. As shown in Figures 10 and 11, flat attachment surfaces 121 for abutting and fixing the first plate 20 of the hinge 10 are formed above and below one end of the front side of the inner door 120.

[0024] 2, a pair of screw holes 122 for fixing the first plate 20 with screws 24 is provided in the mounting surface 121 of the inner door 120. In addition, as shown only partially in FIG. 3, a pair of shafts 123 aligned with the screw holes 122 are provided between the screw holes 122 and protrude perpendicularly from the mounting surface 121. The shafts 123 are fitted into holes 23 of the first plate 20 (described later) to position the first plate 20 so as to be fixed to the mounting surface 121, but there was a restriction on their height due to design reasons. That is, the shafts 123 are set to a dimension that actually passes through the holes 23 of the first plate 20 and protrudes slightly upward, i.e., slightly higher than the thickness of the first plate 20.

[0025] As shown in Figures 4 to 7, the first plate 20 of the hinge 10, which is fixed to the inner door 120, is provided with three axle tubes 21 lined up along one edge in the longitudinal direction of the first plate 20. The center of the central axle tube 21 among the axle tubes 21, i.e., the axle core 11 at that position, is the center of gravity of the entire hinge 10. A pair of screw holes 22 is provided near both ends of the first plate 20. Furthermore, a pair of hole portions 23 is provided between each screw hole 22, and is aligned with the screw holes 22.

[0026] 2, the second plate 30 of the hinge 10, which is fixed to the housing 101, is composed of an orthogonal surface portion 30a that is orthogonal to the attachment surface 121 of the inner door 120 to which the first plate 20 is fixed, and a parallel surface portion 30b that is bent at a right angle from the tip edge of the orthogonal surface portion 30a in a direction away from the first plate 20. Here, the orthogonal surface portion 30a is a portion that is not shown in detail, but is adapted to the shape of the attachment location on one side end of the periphery of the opening of the housing 101.

[0027] As shown in Figures 4 to 7, the orthogonal surface portion 30a is provided with two axle tubes 31 aligned along one longitudinal edge thereof. Here, each axle tube 31 is aligned linearly and alternately meshes with the axle tubes 21 of the first plate 20 described above, and the axle core 11 is inserted through them. In addition, a pair of screw holes 32 is provided near both ends of the parallel surface portion 30b. Furthermore, between each screw hole 32, there is provided a potbellied hole 33, which is formed by a wide groove of a predetermined width and a narrower narrow groove. Here, the potbellied hole 33 corresponds to an example of the "hooked portion" of the present invention.

[0028] More specifically, when the potbelly hole 33 is hooked onto a hook at the mounting location on the housing 101 (not shown), the flange of the hook that matches the wide groove passes through it. When the hook then moves relatively up to the narrow groove above, the flange cannot pass through in the horizontal direction, preventing it from coming loose. At this retaining position, the screw hole 32 of the second plate 30 matches a screw hole at the mounting location on the housing 101, allowing it to be fixed with a screw. Here, the hook corresponds to an example of the "hooking portion" of the present invention.

[0029] <Mounting structure of hinge 10> 1 and 2, the mounting structure of the hinge 10 is a structure for mounting the first plate 20 of the hinge 10 to the inner door 120. That is, when the first plate 20 is placed and fixed on the substantially horizontal mounting surface 121 of the inner door 120, a rib 125 is provided on the inner door 120 itself to support the entire hinge 10 directly below the center of gravity if it comes off the mounting surface 121, thereby preventing it from falling. Here, the rib 125 corresponds to an example of the "support portion" of the present invention.

[0030] 9 and 10, when the inner door 120 of the signal controller 100 is normally installed, the reference planes on the front and back of the inner door 120 form vertical planes. However, when the first plate 20 of the hinge 10 is fixed to the inner door 120 before being connected to the housing 101, the inner door 120 is held in a generally horizontal state overall, including the mounting surface 121 to which the first plate 20 is fixed, as shown in Fig. 11. At this time, a rib 125 is integrally provided on the other end surface 124 of the inner door 120 that hangs down perpendicularly from the edge of the mounting surface 121 (including the front side).

[0031] As shown in Figures 1 and 2, the rib 125 is a narrow plate-like member that rises perpendicularly to the other end surface 124. One end of the rib 125 is perpendicular to the other end surface 124, and when the hinge 10 is fixed, the rib 125 forms a horizontal upper end that is disposed so as to abut against the underside of the core 11, which is directly below the center of gravity of the entire hinge 10. To be precise, "directly below the center of gravity of the hinge 10" corresponds to the position directly below the center of the core 11 in the axial direction. To be precise, the upper end of the rib 125 does not abut directly against the underside of the core 11 itself, but corresponds to the lower end of the shaft tube 21 through which the core 11 is inserted.

[0032] On the other hand, the other end (lower end) of the rib 125 is gently tapered. Such a rib 125 extends in the vertical direction when the hinge 10 is fixed. Furthermore, the inner door 120 is integrally molded from resin, and the rib 125 is provided integrally as part of the other end surface 124 of the inner door 120 itself. The joint between the other end surface 124 and the rib 125 is reinforced by forming a rounded cross section all around.

[0033] Two such ribs 125 are provided so as to abut against the underside of the axis 11 of the hinge 10 at two locations spaced apart in the axial direction. To be precise, one of the two ribs 125 is located directly below the center of the axis 11, which is the center of gravity of the entire hinge 10, and the other rib 125 is located at a location slightly away from the center of the axis 11. These two ribs 125 can support the underside of the axis 11, which is directly below the center of gravity of the entire hinge 10, in a more stable state.

[0034] As shown in Figures 3(e') and (f'), the rib 125 is disposed at a position where it abuts against the axle tube 21 of the first plate 20 of the axle tubes 21, 31 of the plates 20, 30 of the hinge 10. Here, the position of the axle tube 21 of the first plate 20 does not change relative to the inner door 120. Therefore, the axle tube 21 of the first plate 20 does not come into contact with the axle tube 21 while rotating against the axle tube 125, and no friction occurs between the axle tube 21 and the rib 125. On the other hand, since the axle tube 31 of the second plate 30 rotates relative to the rib 125, if it were to abut against the rib 125, wear would occur.

[0035] 3(e'), a clearance k is provided directly below the center of gravity of the entire hinge 10 when the hinge 10 is fixed, that is, between the lower end of the axle tube 21 and the upper end of the rib 125, to prevent the first plate 20 from floating away from the mounting surface 121 due to the two abutting against each other first. If there was no clearance k between the lower end of the axle tube 21 and the upper end of the rib 125, and if a design error caused the two to abut against each other before the first plate 20 abutted against the mounting surface 121, there was a risk that the first plate 20 would inadvertently float above the mounting surface 121, making it more likely to become misaligned when screwed in.

[0036] That is, by providing the clearance k, when fixing the hinge 10, just before the screw 24 is fixed, the lower end of the shaft cylinder 21 drops slightly by the amount of the clearance k to the upper end of the rib 125, and the first plate 20 is tilted to an extent that it does not shift out of position relative to the mounting surface 121. In this state, compared to when the first plate 20 is separated from the mounting surface 121 so as to float, it is less likely to shift out of position when fastened with the screws.

[0037] 9, the other second plate 30 of the hinge 10 is fixed to one side edge of the opening periphery of the housing 101, and flat mounting locations are formed above and below this one side edge to abut and fix the parallel surface portions 30b of the second plate 30 of the hinge 10. A hook protrudes from this mounting location, and when the second plate 30 is fixed to the housing 101, the hook is engaged with the potbelly hole 33 of the second plate 30 as described above, thereby enabling the inner door 120 to be held together with the hinge 10 against the opening periphery of the housing 101. Here, the hook is formed with a flange that passes through the wide groove of the potbelly hole 33 horizontally but not through the narrow groove, preventing it from coming off.

[0038] <Function of the mounting structure of hinge 10> The installation work of the hinge 10 in the signal controller 100 will be described below. In order to reduce weight and costs, recent signal control devices 100 have been required to mold metal components that can be replaced with resin as much as possible instead of metal such as sheet metal. As part of this shift to resin, the inner door 120, which is mainly used to attach the control unit 130, is also molded as a single unit from synthetic resin.

[0039] This allows various additional structures to be integrally molded onto the inner door 120, and the rib 125, which is the core of the present invention, can also be easily formed integrally in the illustrated shape protruding from the other end surface 124. Therefore, there is no need to form the rib 125 separately from the inner door 120 itself and attach it later. Such rib 125 is designed in a shape that will not create an undercut when the inner door 120 is molded.

[0040] Next, the attachment of the hinge 10 to the inner door 120 will be described in accordance with the assembly process shown in Figure 14(c). As shown in Figure 11, when the hinge 10 is fixed to the inner door 120 with screws, the inner door 120 is held in a substantially horizontal position with its attachment surface 121 facing upward. Then, as shown in Figures 3(d) to (e), the first plate 20 of the hinge 10 is positioned on the attachment surface 121. At this time, by fitting the shaft 123 on the attachment surface 121 side into the hole 23 in the first plate 20, accurate positioning is possible, with both screw holes 22, 122 aligned vertically. However, the fitting relationship between the hole 23 and the shaft 123 alone is not enough to prevent the hinge 10 from rotating under its own weight.

[0041] With the first plate 20 positioned in this way, the axis 11 (axis tube 21), which is the center of gravity of the entire hinge 10, is located horizontally outward from the mounting surface 121. Therefore, when the positioned hinge 10 is released, the hinge 10 will try to rotate due to the rotation moment caused by its own weight, but since it is supported from below by the rib 125 located directly below the center of gravity of the hinge 10, it can be maintained in that position even when the hand is released.

[0042] 3(e') and (f'), a clearance k is provided between the lower end of the axle tube 21, which is directly below the center of gravity of the entire hinge 10, and the upper end of the rib 125. Therefore, the first plate 20 is tilted slightly to the left in the figure by the height of this clearance k, but the fitting relationship between the hole 23 and the axle 123 is maintained. The presence of this clearance k makes it possible to prevent the first plate 20 from floating above the mounting surface 121, as described above, and makes it less likely for the first plate 20 to become misaligned when screwed in.

[0043] In addition, since there are two ribs 125 that abut against the underside of the axis 11 of the hinge 10 at two points spaced apart in the axial direction, it is possible to more stably and reliably support from below the center of gravity of the entire hinge 10. Furthermore, because the upper end of the ribs 125 abuts against the axis tube 21 of the first plate 20, which does not rotate relative to the ribs 125, no friction occurs between the ribs 125 and the axis tube 21, and there is no risk of the ribs 125 wearing out.

[0044] According to the mounting structure of the hinge 10 as described above, when the first plate 20 of the hinge 10 is fixed to the inner door 120 with screws, it is possible to support the area directly below the center of gravity of the hinge 10 without using a special jig (see FIG. 14(b)). Therefore, even if you let go of the hinge 10 in the state shown in FIGS. 3(e') and (f'), the hinge 10 will not shift position, improving the efficiency of the mounting work and reducing costs. In other words, it is clear that the number of work steps is reduced when comparing the assembly process using the mounting structure of the hinge 10 of the present invention shown in FIG. 14(c) with the conventional assembly process shown in FIGS. 14(a) and (b).

[0045] Next, the hinge 10 fixed to the inner door 120 is attached to the housing 101, which is in a vertical position at this time, as shown in Figure 12. The inner door 120 is also set upright to match the vertically-placed housing 101, and the second plate 30 of the hinge 10 already fixed to the inner door 120 is fixed with screws to a mounting location on the periphery of the opening of the housing 101. When fixing in this way, first, a hook at the mounting location (not shown) is hooked into the potbelly hole 33 on the second plate 20.

[0046] At this time, after the flange of the hook is passed through the wide groove below the potbelly hole 33, the inner door 120 is lowered and the hook is moved relatively to the narrow groove above the potbelly hole 33. This makes it possible to hook the inner door 120 together with the hinge 10 to the housing 101 without having to hold it by hand. In this state, the second plate 30 of the hinge 10 does not rotate, making it easy to perform the screw fastening work to fix the second plate 30 to the mounting location on the housing 101. Note that even if the inner door 120 is opened 180 degrees from the housing 101 after attachment, the first plate 20 is separated from the parallel surface portion 30b of the second plate 30 by the width of the vertical surface portion 30a, so the hook does not interfere with the first plate 20.

[0047] <Configuration and effects of the present invention> Although the present embodiment has been described above, the present invention is not limited to the above-described embodiment. The present invention derived from the above-described embodiment will be described below.

[0048] First, the present invention provides a mounting structure for a hinge 10 in which a pair of plates 20, 30 are rotatably connected to each other by a shaft 11, When one plate 20 of the hinge 10 is placed and fixed on a substantially horizontal mounting surface 121 of an object to be mounted (inner door 120), a support portion (rib 125) is provided on the object to be mounted (inner door 120) to support the entire hinge 10 located outside the mounting surface 121 directly below the center of gravity and prevent it from falling.

[0049] According to this mounting structure of the hinge 10, it is possible to support the area directly below the center of gravity of the hinge 10 from below without using any special jig when fixing the hinge 10. Therefore, even if you let go of the hinge 10 when fixing it, the hinge 10 will not fall or shift out of position, which improves the efficiency of the installation work and reduces costs.

[0050] Furthermore, in the present invention, the support portion is provided as a rib 125 protruding from the other end surface 124 that is approximately perpendicular to the mounting surface 121 of the one mounting object (inner door 120), and one end of the rib 125 abuts against the underside of the axis 11, which is directly below the center of gravity of the entire hinge 10 when fixed.

[0051] With this configuration, the rib 125 forming the support portion not only supports the area directly below the center of gravity of the entire hinge 10, but also structurally reinforces the other end surface 124 that is approximately perpendicular to the mounting surface 121. Furthermore, by providing the rib 125 integrally with one mounting object (inner door 120) itself, the number of parts and assembly steps can be reduced compared to when the rib 125 is attached later as a separate part.

[0052] Furthermore, the present invention is characterized in that the rib 125 is arranged at a position where it abuts against the axle tube 21 of one of the plates 20, among the axle tubes 21, 31 at the opposing end edges of each plate 20, 30 through which the axis 11 of the hinge 10 is inserted. With this configuration, the shaft tube 21 of one plate 20 does not rotate relative to the rib 125 with which it abuts, and no friction occurs between the rib 125. Therefore, there is no risk of the rib 125 being worn down due to contact with the shaft tube 21.

[0053] Furthermore, the present invention is characterized in that two ribs 125 are provided so as to abut against the lower side of the shaft core 11 of the hinge 10 at two points spaced apart in the axial direction. With this configuration, the two ribs 125 can support the lower side of the shaft core 11, which is directly below the center of gravity of the entire hinge 10, in an even more stable state.

[0054] Furthermore, the present invention is characterized in that a clearance k is provided between the support portion (rib 125) and the center of gravity of the entire hinge 10 when fixed, so that the two abut first to prevent one plate 20 from moving away from the mounting surface 121. With this configuration, even if the hinge 10 tilts to a degree that does not cause it to fall, the clearance k between the center of gravity of the entire hinge 10 and the support portion (rib 125) prevents one of the plates 20 of the hinge 10 from being significantly displaced from the mounting surface 121.

[0055] In addition, the present invention provides a mounting surface 121 provided with a shaft 123 for positioning the one plate 20 in a fixed state, The one plate 20 is characterized in that a hole 23 into which the shaft 123 fits is provided. With this configuration, by fitting the shaft 123 on the mounting surface 121 side into the hole 23 in one plate 20 of the hinge 10, it becomes possible to more accurately position the one plate 20 relative to the mounting surface 121. In addition, since the hinge 10 is supported directly below its center of gravity by the support portion (rib 125), it becomes possible to support the hinge 10 more reliably.

[0056] In addition, the present invention provides a hooked portion (potbellied hole 33) on the other plate 30 of the hinge 10, which can be hooked onto a hook (hook) at a mounting location of another mounting object (housing 101) to which the other plate 30 is fixed, When the other plate 30 of the hinge 10 is fixed to the other object to be attached (housing 101), the hinge 10 and the one object to be attached (inner door 120) can be held relative to the other object to be attached (housing 101) by engaging the hook portion (hook) with the hooked portion (daruma hole 33).

[0057] With this configuration, when the hinge 10, which has already been fixed to one object to be attached (inner door 120), is now fixed to another object to be attached (housing 101), the hooked portion (potbellied hole 33) on the other plate 30 of the hinge 10 is hooked onto the hooking portion (hook) on the attachment location of the other object to be attached (housing 101).

[0058] This makes it possible to hold one attachment object (inner door 120) together with the hinge 10 to another attachment object (housing 101) without holding the first attachment object by hand. Therefore, the other plate 30 does not rotate unintentionally, and the task of fixing it to another attachment object (housing 101) can be easily performed.

[0059] Furthermore, the present invention is characterized in that the one attachment object (inner door 120) is integrally molded including the support portion (rib 125). This structure allows various additional structures to be molded integrally with the object to be attached (inner door 120), and the support portion (rib 125) can be easily provided integrally, thereby reducing the number of parts and assembly steps.

[0060] Although the present embodiment has been described above with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions that do not deviate from the gist of the present invention are also included in the present invention. For example, the object to which the hinge 10 is attached is not limited to the housing 101 and inner door 120 of the traffic light controller 100, but can be applied to objects in various fields. Furthermore, the specific shape of the hinge 10 is not limited to the above-described embodiment. [Industrial Applicability]

[0061] The present invention is not limited to the attachment of a housing and an inner door in a signal control device, but can be used in various fields to connect one attachment object, such as a door or a lid, to another attachment object, such as the main body, so that it can be opened and closed (rotated).
