Abstract
Description
[Technical Field]
[0001] The present invention relates to a traffic signal controller that controls a traffic signal. [Background technology]
[0002] Traffic signals installed at road intersections and other locations are equipped with a signal controller that controls the lighting of signal lights. The housing of this signal controller is usually installed with a door on the housing body sealed to prevent rain and dust from entering from the outside and to protect the internal equipment.
[0003] However, if a power outage occurs due to a disaster such as an earthquake, traffic lights may go out, causing traffic congestion. To avoid this situation, there is a known technology that operates traffic lights by connecting, for example, an electric vehicle battery or an internal combustion generator to a control device.
[0004] In traffic signal control devices equipped with an external power supply function for use in emergencies such as disasters and power outages, the external power supply cable interferes with the door during external power supply, making it impossible to close the door. This poses a problem, requiring police officers to be on standby at all times.
[0005] In response to such problems, for example, Patent Document 1 discloses a traffic light controller having the following configuration: The traffic light controller includes a housing main body having an opening and a notch or hole formed at an end of the opening, a door capable of opening and closing the opening, and a cover member (sealing member) provided on the main body and capable of opening and closing the notch or hole, the cover member being rotatably or slidably connected to the main body. The cover member can be opened to insert an electric cable for external power supply into the main body, and after external power supply has ended, the electric cable is removed and the cover member is closed. [Prior art documents] [Patent documents]
[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2018-173997 Summary of the Invention [Problem to be solved by the invention]
[0007] However, in Patent Document 1, the cover member serving as a sealing member is connected to the main body in a rotatable or slidable manner. Therefore, even if the door is closed with the cover member left open after the external power supply is terminated in an emergency, it is difficult for police officers or other workers to recognize this state, and there is a risk that they will end their work as is. This has led to problems such as rain and dust getting in through the open portion.
[0008] In view of the above circumstances, an object of the present invention is to provide a traffic light controller that can prevent a seal member from being forgotten to be attached after being removed from a housing body. [Means for solving the problem]
[0009] In order to achieve the above object, a signal controller according to one embodiment of the present invention includes a control device, a housing body, a door, and a seal member. The control device controls the traffic signal lights and has a terminal section that can be connected to an external power source. The housing body has an opening and a notch formed at the opening edge, which is the peripheral portion of the opening, through which a power supply cable connecting the external power source and the terminal portion can be inserted, and houses the control device. The door is connected to the housing body and is capable of opening and closing the opening. The sealing member has a sealing body that has a first state in which it is fitted into the notch portion or a second state in which it is hung from the notch portion over a predetermined length, and a linear support portion that connects the sealing body and the housing body in the second state and hangs the sealing body from the housing body.
[0010] Because the seal member for this signal controller includes a seal body and a support part, even if the seal body is removed from the cutout, the seal member remains in the second state, hanging from the housing body via the support part. Therefore, even if the seal member is in the second state during a disaster or other such event, and a power supply cable is passed through the cutout from the outside to perform power supply work, and the door is closed without fitting the seal body into the cutout, the seal member hanging from the housing body makes it easy for the worker to find the seal member, making it possible to prevent forgetting to attach the seal member to the cutout after the power supply work is completed.
[0011] The cutout portion may have a first surface that faces the surface to which the opening edge portion belongs and is on the inside of the housing body, a second surface opposite the first surface, and a bottom having a hole that penetrates the first surface and the second surface. In this case, for example, the support portion may be inserted through the hole portion so as to be movable in the extending direction of the support portion. This allows the hole to restrict movement of the support portion when transitioning from the first state to the second state, thereby preventing the support portion from coming into contact with the control device.
[0012] The support portion may have a first end portion that is engaged with the hole portion from the first surface side in the second state. This allows the support part to be held in the second state by having the first end caught and fixed in the hole.
[0013] The support portion may have a second end coupled to the seal body. In this case, for example, the second end portion has an expanded diameter portion that is press-fitted into the hole from the second surface side when the seal portion main body abuts against the bottom portion. As a result, in the first state, the enlarged diameter portion is press-fitted into the hole portion, thereby ensuring waterproofing of the housing body.
[0014] The notch may further include a restricting portion that restricts movement of the seal body in a direction parallel to the height in the first state.
[0015] The seal body may have a groove parallel to the direction in which the seal body fits. In this case, for example, the restricting portion engages with the groove portion.
[0016] The support portion may be flexible.
[0017] In order to achieve the above object, a housing according to one embodiment of the present invention includes a housing body, a door, and a sealing member. The housing body has an opening and a notch formed in the opening edge, which is the periphery of the opening. The door is connected to the housing body so that the opening can be opened and closed, and when the opening is closed, a first device housed inside the housing body can be connected to a second device located outside the housing body via a cable inserted into the cutout portion. The sealing member has a sealing body that has a first state in which it is fitted into the notch portion or a second state in which it is hung from the notch portion over a predetermined length, and a linear support portion that connects the sealing body and the housing body in the second state and hangs the sealing body from the housing body.
[0018] The notch may be provided in a lower portion of the housing body. [Effects of the Invention]
[0019] As described above, according to the present invention, it is possible to realize a traffic light controller that can prevent the sealing member from being forgotten to be attached after being removed from the housing body. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION
[0021] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0022] [Configuration of signal controller]
[0023] 1 is a diagram showing a traffic signal 1 equipped with a signal controller according to an embodiment of the present invention. The traffic signal 1 includes, for example, signal lights 2 for vehicles and pedestrians, and a signal controller 100 that controls these signal lights 2. The signal lights 2 and the signal controller 100 are attached to a support pole 3, and are connected via an electric cable.
[0024] In most cases, multiple traffic lights 1 are installed at the sides of intersections. One traffic light controller 100 is installed at each intersection. Most traffic light controllers 100 are attached to a support pole 3 at a height within reach of a person, for example, at a height of 1 to 1.5 m above the road surface.
[0025] Fig. 2 is a perspective view showing an example of the internal structure of the traffic light controller 100. Note that in Figs. 3, 4, and 8 described below, illustration of internal devices and the like inside the housing 101 is omitted. Here, in Figs. 2 to 8, the X-axis direction and the Y-axis direction indicate horizontal directions that are orthogonal to each other, and the Z-axis direction indicates the vertical axis direction. The direction of gravity in the drawings is the negative direction of the Z-axis.
[0026] The signal controller 100 includes a housing 101 , a control device 120 , a manual operation unit 130 , a breaker unit 140 , and an external power supply unit 200 .
[0027] The housing 101 includes a housing body 102 having an opening 107, and a door 103 connected to the housing body 102 and provided so as to be able to open and close the opening 107. As will be described later, a notch 110 is formed in the lower part of opening edge 108, which is the peripheral edge of opening 107 of housing main body 102, and a seal member 150 that can fit into notch 110 is provided on housing main body 102 (see FIG. 2). In this embodiment, the height of housing 101 in the Z-axis direction is approximately 800 mm.
[0028] An opening 103a is provided at a predetermined position on the door 103, and a sub-door (not shown) is connected to the front side of the door 103 (the back side of the paper in FIG. 2) so that the opening 103a can be opened and closed. The door 103 is connected to the main housing 102 by a hinge 104 so that the door 103 can be opened and closed, and similarly, the sub-door is connected to the door 103 by a hinge so that the door 103 can be opened and closed. A locking unit 105 is provided on the door 103 so that the door 103 can be locked to the main housing 102.
[0029] The control device 120 is housed, for example, in the upper part of the housing main body 102, and basically controls the lighting and flashing times of one or more signal lights 2. The control device 120 has an operation panel 121 on the front, and an operator (for example, a police official) can set and change the lighting times and lighting sequence by operating, for example, this operation panel 121. In addition to the above basic functions, the control device 120 may also have a lighting brightness adjustment function and a communication function that enables communication with a computer at a traffic control center.
[0030] The manual operation unit 130 is provided inside the door 103 so as to face the opening 103a of the door 103. Specifically, the manual operation unit 130 is supported by a box body 131 provided so as to close the opening 103a from the inside of the door 103, and is housed between the box body 131 and the sub door.
[0031] The manual operation unit 130 has a function of switching the control of the lighting of the signal light 2 performed by the control device 120 to manual control, and accepting manual operation input from an operator to control the lighting of the signal light 2. For example, at an event or the like, an operator can open the sub door and operate the operation button of the manual operation unit 130 inside the opening 103a to manually switch the lighting of the signal light 2 on and off.
[0032] The breaker unit 140 is housed in the main body 102 and is disposed, for example, below the control device 120. The breaker unit 140 is connected to (a power supply cable from) a commercial power source (not shown), and opens and closes the power supply path from the commercial power source to the signal controller 100, and cuts off the power supply when the current flowing through the power supply path exceeds a specified value.
[0033] The external power supply unit 200 has an external power supply terminal section 220, which is a terminal section that can be connected to an external power source in an emergency, such as a disaster, and a manual changeover switch section 230 that includes a switch that can be manually operated to select the power source (commercial power source or external power source).
[0034] A standardized external power supply terminal unit 220 is mounted, such as a terminal unit for an electrical appliance that is widely used even in ordinary households. Specific standards include C 8303 in the Japanese Industrial Standards (JIS) and 60884 in the International Electrotechnical Commission (IEC). Such a standardized external power supply terminal unit allows a commercially available device having an external power supply function or a general-purpose plug or socket to be connected to the external power supply terminal unit 220.
[0035] The manual changeover switch section 230 has a toggle switch that can be manually operated, for example, that switches the wiring connection path by moving an operation lever. This operation lever is enclosed in a protective cover attached to the front surface of the external power supply unit 200, and can be operated by an operator inserting his / her hand through an opening in the protective cover.
[0036] The external power supply unit 200 has a power supply path that can be connected to a commercial power source via the breaker unit 140, and a second power supply path that is connected to the external power supply terminal section 220. These power supply paths are connected to the contacts of the manual changeover switch 230. One of these paths is selected by the manual changeover switch 230, and the power is supplied to the control device 120.
[0037] Figure 3 is an oblique view showing the main parts of the signal controller 100, where (A) shows a first state in which the sealing member 150 is fitted into the cutout portion 110, and (B) shows a second state in which the sealing member 150 is suspended from the cutout portion 110 over a predetermined length.
[0038] The details will be described later, but the first state is a state in which, for example, the seal body 151 is used in normal times, and the groove 153 formed in the seal body 151 is fitted into the protrusion 112 of the cutout 110 along the X-axis direction. The second state is a state in which, for example, the seal body 151 is moved along the X-axis direction, removed from the cutout 110, and left hanging.
[0039] 3(A) and 3(B), the cross section of opening edge 108 in the X-axis direction is formed in an L-shape. That is, opening edge 108 has base 108a that protrudes forward (positive direction of the X-axis) of housing main body 102, and front surface 108b that is bent at an angle of 90° from base 108a toward the outer periphery of opening 107. A gasket (not shown) provided on inner side 103b of door 103 along the shape of front surface 108b comes into surface contact with front surface 108b of opening edge 108, whereby door 103 closes opening 107, i.e., main body 102 is closed.
[0040] A notch 110 is provided at a predetermined position in the lower part of the housing body 102, at the opening edge 108. In this embodiment, the notch 110 is provided on the opposite side of the lower part of the housing body 102 from the hinge 104 (see FIGS. 2, 3A, and 3B).
[0041] Fig. 4 is an enlarged view of the notch 110, and Fig. 5 is an enlarged view of the seal member 150. The first and second states shown in Figs. 3(A) and 3(B) will be described with reference to Figs. 4 and 5.
[0042] 4, the notch 110 is formed so as to penetrate the opening edge 108 in the Z-axis direction. Specifically, a portion of the base 108a is cut out over a predetermined range in the Y-axis direction. Furthermore, when viewed from the X-axis direction, the front surface 108b is cut out over a range in the Y-axis direction that is wider than the predetermined range cut out of the base 108a, with the cut-out part of the base 108a as the center.
[0043] A seal body 151 (described later) is fitted into the cutout space W of the cutout portion 110 (see FIGS. 3A and 5). The cutout portion 110 has a bottom 111 having a first surface 111A (see FIG. 6) that faces the surface to which the front surface 108b belongs and is on the inside of the housing body 102, a second surface 111B opposite to the first surface 111A, and a hole 111C that penetrates through the first surface 111A and the second surface 111B.
[0044] The cutout portion 110 further has a first protrusion 112A that protrudes from the base portion 108a in the positive direction of the Y axis toward the space W, and a second protrusion 112B that protrudes from the base portion 108a in the negative direction of the Y axis toward the space W. Hereinafter, the first protrusion 112A and the first protrusion 112B will be collectively referred to as the protrusion 112.
[0045] Furthermore, the cutout portion 110 further includes a front cutout portion 113 formed in the cross section of the front portion 108b.
[0046] As shown in FIG. 5, the seal member 150 has a seal body 151 as a main body, and a linear support portion 152 provided so as to protrude from the seal body 151 in the negative direction along the X axis.
[0047] The seal body 151 is formed in a roughly rectangular parallelepiped shape and has a first seal surface 151A facing the inside of the housing body 102, a second seal surface 151B opposite to the first seal surface 151A, and a seal upper surface 151C on the upper surface side of the seal body 151.
[0048] The seal portion main body 151 further has grooves 153 that are parallel to the X-axis direction and the Y-axis direction. The grooves 153 are provided on both side portions of the seal portion main body 151 in the Y-axis direction. The grooves 153 are formed from the first seal portion surface 151A toward the second seal portion surface 151B. The grooves 153 are provided on the seal portion main body 151 on the seal portion upper surface 151C side. As shown in FIG. 3(A), the seal portion upper surface 151C is located more positively than the base portion 108a in the Z-axis direction, and the grooves 153 sandwich the protrusion 112.
[0049] The support part 152 is provided integrally with the first seal part surface 151A at approximately the center thereof. The support part 152 has a support part main body 152A which is a main body part, a second end part 152C of the support part main body 152A which is connected to the seal part main body 151, and a first end part 152B provided on the opposite side to the second end part 152C. Furthermore, the support portion 152 is inserted through the hole portion 111C so as to be movable in the extending direction of the support portion main body 152A.
[0050] The support body 152A is linear, and in this embodiment, has a length of 100 mm and a diameter of 3.5 mm. In this embodiment, the support body 152A is roughly linear and string-like, and has a predetermined elasticity. The diameter of the support body 152A is not particularly limited as long as it is smaller than the diameter of the hole 111C. In this embodiment, the diameter of the hole 111C is 5 mm.
[0051] The first end 152B has an approximately truncated cone shape. In this embodiment, the diameter of the lower surface S of the first end 152B that comes into contact with the support portion main body 152A is 7 mm.
[0052] The second end 152C is a hemisphere. In this embodiment, the second end 152C is a hemisphere with a radius of 5 mm, and the bottom surface of the second end 152C is in contact with the first seal surface 151A. Of course, the second end 152C is not limited to a hemisphere, and may be a sphere, and may have an expanded diameter portion with a diameter larger than that of the support portion main body 152A. Furthermore, the hemisphere and sphere do not have to be in contact with the first seal surface 151A.
[0053] The seal body 151 is made of a flexible material such as rubber, etc. Examples of rubber that can be used include EPDM and silicone. The support portion 152 is made of a flexible material, such as EPDM or silicone.
[0054] In the first state, second seal surface 151B and front surface 108b are approximately flush with each other in the X-axis direction, so door 103 can be closed without any gaps. As shown in Fig. 3(A), seal member 150 is fitted into notch 110, so that rain and dust can be prevented from entering housing 101 through notch 110 when door 103 is closed (see Figs. 4 and 5). As a result, when door 103 is closed in the first state, the interior of housing 101 can be kept almost airtight.
[0055] The protrusion 112 is parallel to the Y-axis direction and can guide the groove 153 slidably in a direction parallel to the X-axis direction, thereby making it possible to easily shift from the first state to the second state and from the second state to the first state. The seal member 150 can prevent the seal member 150 from coming off the protrusion 112 even if an action such as pushing the seal member 150 is applied from the outside when the door 103 is in the first state where it is closed.
[0056] FIG. 6 is an enlarged view of the vicinity of hole 111C in the first state in which seal member 150 is fitted into notch 110, and is a cross-sectional view seen from the Z-axis direction. As shown in FIG. 6, in the first state, when the seal body 151 abuts against the bottom 111, the second end 152C is inserted into the hole 111C from the second surface 111B side. In the first state, hole 111C and second end 152C are at the same height from base 108a along the Z-axis direction. Hole 111C and second end 152C have the same diameter. While the diameter of second end 152C is the same as that of hole 111C in this embodiment, it is not limited thereto and may be larger than that of hole 111C.
[0057] As shown in Fig. 3(B), in the second state, the predetermined length from the notch 110 to the seal body 151 is approximately 100 mm. In this embodiment, the predetermined length is 100 mm, but it is not limited to this and may be any length that prevents the seal body 151 from touching the ground and that is easily visible. For example, the seal body 151 may be hung at a position between 50 cm and 100 cm above the road surface.
[0058] Furthermore, because support portion 152 is approximately linear and has a predetermined elasticity, it is less likely to become tangled with other wiring inside housing 101 and can smoothly transition from the first state to the second state. Furthermore, because it has a predetermined elasticity, support portion 152 can be maintained even when bent from notch portion 110 in the direction of gravity.
[0059] FIG. 7 is an enlarged view of the vicinity of hole 111C in the second state in which the power supply cable 50 is hung from the notch 110 for a predetermined length, and FIG. 8 is a view in which the power supply cable 50 is inserted into the housing 101 through the notch 110, where (A) is a view showing the state when the door is closed, and (B) is a view showing the inside when the door is closed. 3(B) and 7, in the second state, the seal body 151 is pulled in the direction of gravity. As a result, the lower surface S of the first end 152B is pulled toward the bottom 111 and is locked by the hole 111C. The diameter of the lower surface S of the first end 151B may be formed to be larger than the diameter of the hole 111C.
[0060] Also, as shown in Figure 3(B), in a second state in which the sealing member 150 is removed from the cutout portion 110 and hangs from the cutout portion 110 for a predetermined length, even when the door 103 is closed, the inside and outside of the housing 101 are in communication via the cutout portion 110 (see Figures 8(A) and (B)).
[0061] Here, we will explain examples of use in the states shown in FIGS. 3(B), 8(A), and 8(B). For example, if the power supply from the commercial power source is interrupted due to a disaster or other reason, the traffic light 1 may go out, causing traffic congestion. To avoid such a situation, for example, it is necessary to operate the traffic light 1 by connecting a battery installed in a vehicle (such as a police vehicle) to the control device 120. To do this, an operator opens the door 103, connects a power supply cable 50 (see FIGS. 8(A) and 8(B)) connected to an external power source to the external power supply terminal 220, and switches the manual changeover switch 230 to the external power supply side. At this time, in FIG. 3(A), the operator removes the seal member 150 fitted into the cutout 110 (see FIG. 3(B)). The operator then passes the power supply cable 50 through the cutout 110, connects it to the external power supply terminal 220, and closes the door 103.
[0062] Therefore, the power supply cable 50 can be connected to the external power supply unit 200 inside the housing 101 without exposing the inside of the housing 101 to the outside. This makes it possible to protect the inside of the housing 101 from the outside even during external power supply. Because the inside of the housing 101 is not exposed to the outside, it is possible to prevent wind, rain, and the like from entering the housing 101, thereby preventing damage and failure of the signal controller 100.
[0063] Furthermore, even during external power supply, the door 103 can be closed and locked by the locking unit 105, eliminating the need for monitoring to prevent a person unrelated to the operator from operating the inside of the housing 101, for example, for mischief.
[0064] In this embodiment, since sealing member 150 includes sealing portion main body 151 and support portion 152, sealing member 150 remains suspended from housing main body 151 via support portion 152 even in the second state in which sealing portion main body 151 is removed from cutout portion 110. Therefore, even if sealing member 150 is placed in the second state in the event of a disaster or the like, and power is supplied from the outside by passing power supply cable 50 through cutout portion 110, and then door 103 is closed without fitting sealing portion main body 151 into cutout portion 110, the operator can easily find sealing member 150 because sealing member 150 is suspended from housing main body 102, and it is possible to prevent forgetting to attach sealing member 150 to cutout portion 110 after the power supply operation is completed.
[0065] Furthermore, the seal member 150 may be colored in a conspicuous color such as red or yellow to prevent forgetting to attach the seal member 150 to the notch 110. This makes it easier for the worker to notice it.
[0066] In this embodiment, the support part 152 moves through the hole 111C when transitioning from the first state to the second state. This makes it possible to limit the movement of the support part 152 by the hole 111C, and therefore to prevent the support part 152 from coming into contact with the control device 120 or the external power supply unit 200 during the transition.
[0067] Furthermore, since the diameter of the lower surface S of the first end portion 152B is larger than the diameter of the hole 111C, it is locked in the second state, which allows the support portion 152 to hold the seal portion main body 151 in a hanging state.
[0068] In the first state, second end 152C is press-fitted or inserted into hole 111C from the side of second surface 111B. This allows second end 152C to engage with hole 111C without any gaps, and in the first state, it is possible to prevent rainwater, dust, and the like from entering through hole 111C.
[0069] Because support portion 152 is made of a flexible material, it can be easily accommodated inside housing 101 in the first state. Furthermore, seal member 150 can be easily transitioned from the first state to the second state simply by removing seal portion main body 151 from cutout portion 110 and dropping it down.
[0070] Since the cutout portion 110 according to this embodiment is provided in the lower part of the housing main body 102, even when the sealing member 150 is in the second state, it is possible to prevent wind and rain from entering from the outside as long as the door 103 is closed. Furthermore, since the cutout portion 110 is provided in the lower part, the positions of the cutout portion 110 and the sealing member 150 within the signal controller in the first state are not noticeable, making it difficult for unauthorized persons to tamper with them.
[0071] [Variation 1] The present invention is not limited to the above-described embodiments.
[0072] In the above embodiment, first end 151B has a truncated cone shape and is not fixed in a predetermined position in the first state. However, first end 151B may be fixed in a predetermined position. That is, first end 151B may be screwed near hole 111C, for example.
[0073] As a result, even if the sealing member 150 is removed from the cutout portion 110, it remains suspended from the housing main body 102 (second state) as in the above embodiment, thereby achieving the same effects as in the above embodiment.
[0074] [Variation 2] The support portion 152 and the seal portion main body 151 may be separable.
[0075] For example, first end 151B may be screwed near hole 111C, and second end 152C may be hook-shaped. That is, first surface 151A of seal body 151 has a connecting portion that connects to second end 152C, which is hook-shaped. When transitioning to the second state, second end 152C may be connected to seal body 151, causing seal body 151 to hang.
[0076] Even in this case, even if the sealing member 150 is removed from the cutout portion 110, the state in which it is suspended from the housing main body 102 (second state) can be maintained as in the above embodiment, and therefore the same effect as in the above embodiment can be obtained.
[0077] [Other variations] The seal member 150 may be made of a luminous material, which makes it possible to prevent the worker from forgetting to put on the seal member 150, even if the worker is working in the middle of the night.
[0078] Although the notch 110 in each of the above embodiments is used as a means for passing through a power supply cable for supplying power from an external power source, it may also be used as a means for passing through a cable that connects an internal device (e.g., the control device 120) of the housing 101 with an external computer. This allows an operator to operate the external computer and perform settings for the control device 120, etc., with the door 103 closed.
[0079] The notch 110 is not limited to being provided at the bottom of the housing 101, but may also be provided at the side of the housing 101.
[0080] In this embodiment, the seal portion main body 151 has a rectangular parallelepiped shape, but is not limited to this and may have a cylindrical shape.
[0081] The configurations of the sealing member 150 described with reference to the drawings are merely one embodiment, and can be modified as desired without departing from the spirit of the present invention.
[0082] In this embodiment, the housing 101 is a housing for a traffic light controller, but it is not limited to this and may be a housing that houses various types of devices. The first device housed inside the housing 101 may be a control device for a traffic light controller, or a control device other than a traffic light controller, a computer, a motor, etc. The second device outside the housing 101 may be a power supply device (a battery for an electric vehicle or an internal combustion generator), or a communication device, etc. Furthermore, the cable 50 connecting the first device and the second device may be a power supply cable, a distribution cable, a communication cable (such as a LAN cable or an optical fiber cable), etc. Note that the cable 50 is not limited to this and may also be a hose through which cooling water flows to cool the first device and the second device.
