Description

[Technical Field]

[0001] The present invention relates to a controller that controls, for example, a traffic signal, a housing used in the controller, and an elastic member used in the controller and the housing. [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 provided with an inner door to protect the control unit and prevent rain and dust from entering from the outside.

[0003] For example, Patent Document 1 describes a traffic light controller having a housing with a space for accommodating a control unit, a cover panel (inner door) attached to the housing to enable the space to be opened and closed, and a main door attached to the housing to enable the opening of the housing to be opened and closed. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2015-122025 Summary of the Invention [Problem to be solved by the invention]

[0005] Conventionally, inner doors such as those described in Patent Document 1 have been configured to be held down by two elastic members on both sides, the main door side and the control unit side, to prevent the inner door from vibrating when the signal controller is moved for installation or when vehicles pass nearby after installation. However, in such a configuration, the elastic member on the main door side is attached to the main door with double-sided tape. This makes it difficult to position, makes assembly difficult, and requires two parts to hold down from both sides.

[0006] In view of the above circumstances, an object of the present invention is to provide a controller, a housing, and an elastic member that can improve the workability in assembling the elastic member that holds the inner door and reduce manufacturing costs. [Means for solving the problem]

[0007] A controller according to one aspect of the present invention includes a control unit, a housing, and an elastic member. The housing portion has a main body having an opening and forming an internal space for accommodating the control unit, a first door portion which is provided on the main body so as to be able to open and close the internal space, dividing the internal space into a first space in which the control unit is accommodated and a second space outside the first space, and which has one or more through holes which connect the first space and the second space in a closed state, an opposing portion which is provided on the main body and faces the first door portion within the first space when the first door portion is in a closed state, and a second door portion which is provided on the main body so as to be able to open and close the opening and which covers the first door portion in a closed state. The elastic member has a connection portion that is inserted into the through hole, a first elastic portion that is connected to one end of the connection portion and has a first opposing surface that faces a first surface that is the surface of the first door portion on the opposing portion side, and is pressed by the opposing portion so that the first opposing surface presses the first surface toward the side opposite the opposing portion, and a second elastic portion that is connected to the other end of the connection portion and has a second opposing surface that faces a second surface that is the surface of the first door portion on the second door portion side, and is pressed by the second door portion so that the second opposing surface presses the second surface toward the side opposite the second door portion.

[0008] According to the above-mentioned controller, the elastic member is provided so as to penetrate the first door portion, and it is possible to press the first door portion from both the first space side and the second space side with a single member. This reduces manufacturing costs and suppresses vibration of the first door portion. Furthermore, since the elastic member can be positioned by inserting it into the through-hole, the workability of assembling the elastic member can be improved.

[0009] The first door section may further include a hinge section connected to the main body and rotatably holding the first door section. The through hole is provided on a door edge side of the first door section facing the hinge section.

[0010] At least one of the first elastic portion and the second elastic portion may be configured to be elastically deformed so as to be insertable into the through hole.

[0011] The through hole may be a notched hole formed by cutting out a part of the periphery of the first door portion, and the notched hole may have a restricting portion that restricts the inserted connecting portion from moving toward the periphery of the notched first door portion.

[0012] The limiting portion may overlap at least a part of the connecting portion when viewed from the peripheral edge side of the first door portion where the notch hole is provided.

[0013] The elastic member may be a sponge.

[0014] In order to achieve the above object, a housing according to the present invention includes a housing portion and an elastic member. The housing unit has a main body having an opening and forming an internal space, a first door unit that is provided on the main body so as to be able to open and close the internal space and that has one or more through holes that connect the first space and the second space in a closed state, dividing the internal space into a first space and a second space outside the first space, an opposing unit that is provided on the main body and faces the first door unit within the first space when the first door unit is in a closed state, and a second door unit that is provided on the main body so as to be able to open and close the opening and that covers the first door unit in a closed state. The elastic member has a connection portion that is inserted into the through hole, a first elastic portion that is connected to one end of the connection portion and has a first opposing surface that faces a first surface that is the surface of the first door portion on the opposing portion side, and is pressed by the opposing portion so that the first opposing surface presses the first surface toward the side opposite the opposing portion, and a second elastic portion that is connected to the other end of the connection portion and has a second opposing surface that faces a second surface that is the surface of the first door portion on the second door portion side, and is pressed by the second door portion so that the second opposing surface presses the second surface toward the side opposite the second door portion.

[0015] In order to achieve the above object, the elastic member according to the present invention comprises a connection portion, a first elastic portion, and a second elastic portion. The connection portion is inserted into a through-hole of a third member located between the first member and the second member. The first elastic portion is connected to one end of the connection portion and has a first opposing surface that faces a first surface that is the surface of the third member facing the first member, and when pressed by the first member, the first opposing surface presses the first surface toward the opposite side to the first member. The second elastic portion is connected to the other end of the connection portion and has a second opposing surface that faces the second surface, which is the surface of the third member facing the second member, and when pressed by the second member, the second opposing surface presses the second surface toward the opposite side to the second member. [Effects of the Invention]

[0016] According to the controller of the present invention, the workability in assembling the elastic member that holds the first door portion can be improved, and manufacturing costs can be reduced. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0018] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0019] First Embodiment FIG. 1 is a diagram showing a traffic signal 1 in which a signal controller according to a first embodiment of the present invention is installed. 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 3, and are connected via an electric cable. As an example, in this embodiment, the controller 100 will be described as a signal controller that controls a traffic signal, but of course, the present invention is not limited to this.

[0020] 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.

[0021] FIG. 2 is a perspective view showing a controller 100 according to a first embodiment of the present invention, FIG. 3 is a perspective view of the controller 100 with the second door 103 open, and FIG. 4 is a perspective view of the controller 100 with the first door 106 and the second door 103 open. FIG. 5 is an overall view of the elastic member 200, with (A) being a perspective view and (B) being a front view. FIG. 6 is a view showing the elastic member 200 connected to the first door 106, FIG. 7 is a side cross-sectional view of the controller 100, and FIG. 8 is a cross-sectional view of the controller 100 viewed from above. In the drawings, the X-axis, Y-axis, and Z-axis represent three mutually orthogonal axial directions, with the X-axis corresponding to the width direction of the controller 100, the Y-axis corresponding to the depth direction of the controller 100, and the Z-axis corresponding to the height (gravity) direction of the controller 100.

[0022] The controller 100 includes a housing 101 , a control unit 110 , and a manual operation unit 120 .

[0023] The housing 101 includes a housing unit 101A and an elastic member 200. In this embodiment, the housing unit 101A is made of a magnetic material such as a steel plate and has a box-like shape that defines an internal space W for accommodating the control unit 110. The housing unit 101A includes a main body 102 having a first opening 107 on one side, a first door unit (hereinafter referred to as the inner door) 106 as an inner door provided on the main body 102 so as to be able to open and close the internal space W, an opposing unit 130 provided on the main body 102 and facing the inner door 106 in a closed state in which the inner door 106 is closed, and a second door unit (hereinafter referred to as the outer door) 103 as an outer door connected to the main body 102 and capable of opening and closing the first opening 107. In this embodiment, the height of the housing 101A in the Z-axis direction is approximately 800 mm, and the height of the inner door 106 in the Z-axis direction is approximately 700 mm.

[0024] The outer door 103 is an outer door and has a roughly rectangular shape, and is provided so as to cover the inner door 106 when the first opening 107 is closed (closed state). The outer door 103 has an outer door surface 103A that faces the inner door 106 (elastic member 200) when in the closed state. The outer door surface 103A may be the inner surface of the outer door 103, or a separate outer door surface 103A may be provided. The elastic member 200 and the outer door surface 103A will be described later.

[0025] An opening (not shown) is provided at a predetermined position on the outer door 103, and a sub-door 104 is connected to the front side of the outer door 103 so that the opening can be opened and closed. The outer door 103 is connected to the main body 102 by a hinge 108 so that it can be opened and closed, and similarly, the sub-door 104 is connected to the outer door 103 by a hinge so that it can be opened and closed. As shown in FIGS. 2 and 3, the hinge 108 is provided on the right side when viewed from the Y-axis direction. The outer door 103 is also provided with a locking unit 105 so that the outer door 103 can be locked to the main body 102. In this embodiment, an instruction manual TS and the like are provided on the outer door surface 103A of the outer door 103, stored in a clear file or the like, but the instruction manual TS and the clear file do not have to be provided.

[0026] The facing portions 130 are, for example, L-shaped metal fittings, and in this embodiment, two facing portions 130 are provided along the Z-axis direction. The positions and number of facing portions 130 are the same as the positions and number of elastic members 200, which will be described later. In this embodiment, the facing portions 130 are provided in two locations, one above the other along the Z-axis direction, on the opposite side (the side opposite to the X-axis direction, the left side as viewed from the Y-axis direction) from the side on which the hinges 108 and 106C are provided inside the main body 102. The facing portions 130 are attached to the inside of the main body 102 with separate screws or the like.

[0027] The facing portion 130 has a contact surface 130A that faces an elastic member 200, which will be described later, when the inner door 106 is in the closed state. The elastic member 200 and the contact surface 130A will be described later.

[0028] As described above, the inner door 106 is provided in the main body 102 so as to be able to open and close the internal space W. Furthermore, when the inner door 106 is closed, it divides the internal space W into a first space W1 in which the control unit 110 is housed and a second space W2 outside the first space W1. The inner door 106 is opened and closed as necessary, such as for inspection of the control unit 110, and as shown in FIG. 4, the inner door 106 may be provided with a circuit board 106D. The inner door 106 may be made of a steel plate as described above, or may be made of resin, but is of course not limited to these.

[0029] The inner door 106 has a first surface 106A on the opposing portion 130 side with which an elastic member 200 (described later) comes into contact around a through-hole H (described later), and a second surface 106B on the outer door 103 side with which the elastic member 200 comes into contact around the through-hole H. In this embodiment, the first surface 106A and the second surface 106B are formed with a stepped shape in the Y-axis direction, but are not limited to this. The first surface 106A and the second surface 106B also have an uneven shape in the Y-axis direction (see FIG. 6).

[0030] 2 and 3, the inner door 106 has a hinge portion 106C that is connected to the right side of the main body 102 when viewed in the Y-axis direction and that rotatably holds the inner door 106. That is, in this embodiment, the outer door 103 and the inner door 106 both open to the right when viewed in the Y-axis direction, but they may both open to the left. The inner door 106 also has a fixing mechanism (not shown) that fixes the inner door 106 to the main body 102 near the center of its length along the Z-axis direction. The fixing mechanism is not particularly limited, but may be, for example, a mechanism that holds the inner door 106 using magnetic force such as a magnet.

[0031] The through-hole H communicates the first space W1 and the second space W2 in the Y-axis direction when the inner door 106 is in a closed state. In this embodiment, the shape of the through-hole H is a hole formed in a roughly rectangular ring shape when viewed in the Y-axis direction, but it is not limited to a rectangular shape and may be, for example, a circular shape.

[0032] As shown in Figure 6, the sizes of the through hole H are a first hole diameter H1 parallel to the Z-axis direction, which is the height of the through hole H, a second hole diameter H2 parallel to the X-axis direction, which is the width of the through hole H, and a hole length H3 parallel to the Y-axis direction, which is the depth of the through hole H.

[0033] In this embodiment, the through holes H are provided on the door tip 106T side of the inner door 106 facing the hinge part 106C. Here, the door tip refers to the side opposite to the side (tail end side) on which the hinge part 106C is provided on the inner door 106. The positions and number of the through holes H are two, one above the other, on the door tip 106T side, similar to the opposing part 130 described above.

[0034] The control unit 110 is housed, for example, in the upper part of the main body 102, and basically controls the lighting and flashing times of one or more signal lights 2. The control unit 110 may have an operation panel on the front. A user (for example, a police officer) can set and change the lighting times and lighting sequence by operating the operation panel, for example. In addition to the above basic functions, the control unit 110 may also have a lighting brightness adjustment function and a communication function that enables communication with a computer at a traffic control center.

[0035] The manual operation unit 120 has a function of switching the control of the lighting of the signal light 2 performed by the control unit 110 to manual control, and accepting manual operation input from a user to control the lighting of the signal light 2. For example, at an event, a user can open the sub door 104 and manually switch the lighting of the signal light 2 by operating the operation button of the manual operation unit 120 inside the second opening.

[0036] The elastic member 200 is plate-shaped and has a connecting portion 201 that is inserted into the through-hole H, a first elastic portion 202 that is connected to one end of the connecting portion 201 on the side of the opposing portion 130, and a second elastic portion 203 that is connected to the other end of the connecting portion 201 on the side of the outer door 103. In this embodiment, the elastic member 200 that serves as a buffer material that absorbs external vibrations is formed from sponge, but of course is not limited to this and may be made of, for example, silicone.

[0037] The connecting portion 201 has a rectangular parallelepiped shape extending in the Y-axis direction when the inner door 106 is in a closed state. In the present embodiment, the height Z1 of the connecting portion 201 (the length along the Z-axis direction when inserted into the through-hole H) is longer than the first diameter H1 of the through-hole H, but of course, this is not limited thereto. The height Z1 and the first diameter H1 may be approximately the same, or the height Z1 may be shorter than the first diameter H1. Furthermore, in the present embodiment, the width X1 of the connecting portion 201 (the length along the X-axis direction when inserted into the through-hole H) is longer than the second diameter H2 of the through-hole H, but of course, this is not limited thereto. The width X1 and the second diameter H2 may be approximately the same, or the width X1 may be shorter than the second diameter H2 (see FIGS. 5 and 6 ).

[0038] In addition, in this embodiment, the length Y1 of the connection portion 201 (the length along the Y-axis direction when inserted into the through hole H) is formed to be longer than the hole length H3 of the through hole H, but of course this is not limited to this, and the length Y1 and the hole length H3 may be approximately the same length, or the length Y1 may be shorter than the hole length H3.

[0039] The first elastic portion 202 has a first opposing surface 202A that faces the first surface 106A, which is the surface of the inner door 106 on the opposing portion 130 side, and is pressed by the opposing portion 130, so that the first opposing surface 202A presses (holds) the first surface 106A toward the side opposite the opposing portion 130. In this embodiment, the first opposing surfaces 202A are provided on both ends of the connecting portion 201 in the height Z1 direction. Furthermore, the length of the height Z2 of the first elastic portion 202 on the first opposing surface 202A side is formed to be longer than the length of the first hole diameter H1. As a result, when the connecting portion 201 of the first elastic portion 202 is inserted into the through-hole H, the first opposing surface 202A comes into contact with (presses) the first surface 106A. Furthermore, the length Y2 of the first elastic portion 202 (the length along the Y-axis direction when inserted into the through-hole H) is longer than the distance in the Y-axis direction between the first surface 106A and the first opposing surface 202A when the inner door 106 is in the closed state. As a result, when the inner door 106 is closed, it is pressed as described above.

[0040] The first elastic portion 202 further has a first contact surface 202B that contacts the contact surface 130A of the facing portion 130 when the inner door 106 is in the closed state. The size of the first contact surface 202 is not particularly limited, but may be smaller than the contact surface 130A, for example. The first contact surface 202 may be provided so as to contact a central portion of the contact surface 130A when the inner door 106 is in the closed state.

[0041] When the inner door 106 is in the closed state, the contact surface 130A of the facing portion 130 and the first abutment surface 202B of the first elastic portion 202 come into contact with each other, and when they come into contact, the first elastic portion 202 is pressed from the facing portion 130 toward the inner door 106. The pressed first facing surface 202A of the first elastic portion 202 presses against the first surface 106A of the inner door 106.

[0042] As shown in Fig. 5(B), the shape of the first elastic portion 202 is roughly trapezoidal, with the width tapering from one end of the connecting portion 201 to the first contact surface 202B. This makes it easier to insert the first elastic portion 202 into the through-hole H. Also, as shown in Fig. 5(A) in this embodiment, the width X1 of the connecting portion 201 and the width X1 of the first contact surface 202B are the same, but of course they are not limited to this and may be different.

[0043] The second elastic portion 203 has a second opposing surface 203A that faces the second surface 106B, which is the surface of the inner door 106 facing the outer door 103. When pressed by the outer door 103, the second opposing surface 203A presses (holds) the second surface 106B toward the side opposite the outer door 103. In this embodiment, the second opposing surfaces 203A are provided on both ends of the connecting portion 201 in the height Z1 direction. Furthermore, the length of the height Z3 of the second elastic portion 203 on the second opposing surface 203A side is formed to be longer than the length of the first hole diameter H1. As a result, when the connecting portion 201 of the second elastic portion 203 is inserted into the through-hole H, the second opposing surface 203A comes into contact with (presses) the second surface 106B. Furthermore, the length Y3 of the second elastic portion 203 (the length along the Y-axis direction when inserted into the through-hole H) is longer than the distance in the Y-axis direction between the second surface 106B and the second opposing surface 203A when the outer door 103 is in the closed state. As a result, when the outer door 103 is closed, it is pressed as described above. Furthermore, the length Y3 of the second elastic portion 203 and the length Y2 of the first elastic portion 202 may be the same as or different from each other. The lengths Y2 and Y3 may be adjusted depending on the distance between the first elastic portion 202 and the opposing portion 130, and the distance between the second elastic portion 203 and the outer door 103 when in the closed state (inner door 106 and outer door 103).

[0044] The second elastic member 203 further includes a second abutment surface 203B that abuts against the outer door surface 103A of the outer door 103 when the inner door 106 is closed. The size of the second abutment surface 203 is not particularly limited. For example, if the outer door surface 103A is provided separately, the second abutment surface 203 may be smaller than the outer door surface 103A. If the outer door surface 103A is provided separately, the second abutment surface 203 may be provided to abut against the center of the outer door surface 103A when the inner door 106 is closed. In this embodiment, the second elastic member 203 of the elastic member 200 provided on the upper side in the Z-axis direction is pressed by a clear file containing an instruction manual TS or the like. Of course, this is not limited to this, and a clear file that does not contain an instruction manual TS may also be used. If a clear file is not provided, the second elastic member 203 may abut against the outer door 103 itself, similar to the second elastic member 203 of the elastic member 200 provided on the lower side in the Z-axis direction.

[0045] When the inner door 106 is in the closed state, the outer door surface 103A of the outer door 103 and the second abutting surface 203B of the second elastic portion 203 abut against each other, and when they abut, the second elastic portion 203 is pressed from the outer door surface 103A toward the inner door 106. The pressed second opposing surface 203A of the second elastic portion 203 presses against the second surface 106B of the inner door 106.

[0046] As shown in Fig. 5(B), the shape of the second elastic portion 203 is roughly trapezoidal, with the width tapering from the other end of the connecting portion 201 to the second abutment surface 203B, similar to the first elastic portion 202. This makes it easier to insert the second elastic portion 203 into the through-hole H. Also, as shown in Fig. 5(A) in this embodiment, the width X1 of the connecting portion 201 and the width X1 of the second abutment surface 203B are the same, but of course they are not limited to this and may be different.

[0047] At least one of the first elastic portion 202 and the second elastic portion 203 is configured to elastically deform so as to be insertable into the through hole H. That is, as shown in FIG. 6, the elastic member 200 is inserted into the through hole H, and thereby fitted into the through hole H as shown in FIGS. 4, 7, and 8. At this time, the height Z2 of the first elastic portion 202 is greater than the first hole diameter H1 of the through hole H, and therefore the first elastic portion 202 is inserted while elastically deforming. In this embodiment, as shown in FIG. 6, the first elastic portion 202 is inserted into the through hole H while deforming, but of course, this is not limited thereto, and the second elastic portion 203 may be inserted into the through hole H from the first surface 106A side while elastically deforming.

[0048] The elastic member 200 is inserted into the through-hole H as described above. The method of insertion is to insert the first elastic portion 202 or the second elastic portion 203 of the elastic member 200 into the through-hole H while elastically deforming it. The first opposing surface 202A of the first elastic portion 202 faces the first surface 106A of the inner door 106. The second opposing surface 203A of the second elastic portion 203 faces the second surface 106B of the inner door 106.

[0049] In addition, in this embodiment, when the inner door 106 and the outer door 103 are in an open state, the first opposing surface 202A and the first surface 106A, and the second opposing surface 203A and the second surface 106B are in contact with each other. However, this is not limited to this, and a gap may be provided between the first opposing surface 202A and the first surface 106A, or between the second opposing surface 203A and the second surface 106B, when the inner door 106 and the outer door 103 are in an open state. This makes it possible to reduce the impact on the inner door 106, for example, when the outer door 103 is closed while the inner door 106 is in a closed state. In other words, by providing a gap, the impact is absorbed by the gap when the outer door 103 comes into contact with the second elastic portion 203.

[0050] Furthermore, because the elastic member 200 has the above-described configuration, even if the first elastic portion 202 is pressed by the opposing portion 130 when the inner door 106 is in the closed state, the first elastic portion 202 can be prevented from coming out of the through-hole H. Furthermore, even if the second elastic portion 203 is pressed by the outer door 103 when the inner door 106 and the outer door surface 103 are in the closed state, the second elastic portion 203 can be prevented from coming out of the through-hole H.

[0051] Furthermore, since the elastic member 200 can be positioned simply by inserting the elastic member 200 into the through-hole H, the positioning of the elastic member 200 becomes easy.

[0052] Furthermore, when the inner door 106 and the outer door 103 are in the closed state, the first elastic portion 202 presses the inner door 106 from the opposing portion 130 side by the opposing portion 130, and the second elastic portion 203 presses the inner door 106 from the outer door 103 side by the outer door 103 (pressing from both sides), thereby making it possible to suppress rattling of the inner door 106 due to external vibrations with a single member. This makes it possible to reduce the number of members and keep manufacturing costs down.

[0053] In addition, since the elastic member 200 is made of sponge, it is possible to reduce manufacturing costs. Furthermore, since the elastic member 200 is made of sponge, the difference between whether or not there is an instruction manual TS can be absorbed by the elastic member 200, as described above.

[0054] Furthermore, a through hole H is provided on the door edge T side. This makes it possible to suppress rattling of the inner door 106 by pressing the door edge T side away from the hinge part 106C, which is prone to rattling due to external vibrations. This makes it possible to protect the board 106D, if provided on the inner door 106, from vibrations.

[0055] Furthermore, rattle can be further reduced by holding down the top and bottom of inner door 106 with elastic member 200. This makes it possible to protect board 106D from vibrations when board 106D is provided on inner door 106.

[0056] <Modification> 9 shows a modified example of the through hole H' of the first door portion (inner door) 106'. The following mainly describes the configurations that differ from the first embodiment, and the same reference numerals are used for the same configurations as the first embodiment, and the description thereof will be omitted or simplified.

[0057] The through hole H' is a notched hole formed by cutting out a part of the periphery of the inner door 106' as shown in Fig. 9. The through hole H', which is a notched hole, is opened on the door edge 106T' side as shown in Fig. 9.

[0058] The through hole H' has a first hole HW1 and a second hole HW2 that connects the first hole HW1 to the door edge 106T' (opened) side. The first hole HW1 has a first hole diameter H1, similar to the through hole H in the first embodiment. The hole diameter H1' of the second hole HW2 is shorter than the height Z1. The limiting portion HS' protrudes so that the hole diameter H1' is shorter (narrower) than the first hole diameter H1, and limits the movement of the inserted elastic member 200 (connecting portion 201) toward the peripheral edge side of the inner door 106 (door edge 106T' side).

[0059] The limiting portion HS' is provided so as to overlap at least a part of the connecting portion 201 when viewed from the peripheral edge side (door edge 106T' side) of the inner door 106 where the second hole HW2 of the through hole H', which is a notched hole, is provided.

[0060] That is, as shown in Figure 9, the elastic member 200 (connection portion 201) is inserted into the first hole HW1 via the second hole HW2. The connection portion 201 can be elastically deformed so that it can be inserted into the second hole HW2. The height Z1 of the connection portion 201 inserted into the first hole HW1 is longer than the second hole diameter H1', ​​so that it overlaps with at least a portion of the connection portion 201 when viewed from the peripheral edge side (door edge 106T' side) of the inner door 106. This prevents the elastic member 200 from moving toward the peripheral edge side and slipping out.

[0061] In this embodiment, the elastic member 200 is inserted through the second hole HW2, but of course this is not limited to this, and it may also be inserted through the first hole HW1 through the first elastic portion 202, as in the first embodiment.

[0062] <Other variations> In the above embodiment, the elastic member 200 is entirely made of sponge, but of course it is not limited to this and a part of it (for example, any one of the first elastic part 202, the second elastic part 203, and the connecting part 201) may be made of rubber or silicon. Also, of course, the elastic member 200 does not have to be entirely made of an elastic material, and a part of it may be made of a non-elastic material.

[0063] Furthermore, while the first elastic portion 202 and the second elastic portion 203 are punched into a roughly trapezoidal shape, this is not a limitation and they may have a three-dimensional shape such as a dumbbell shape. Furthermore, they are not limited to a trapezoidal shape and may be hemispherical, cylindrical, or flared toward the opposing portion 130 or outer door 103. The first elastic portion 202 and the second elastic portion 203 are not limited to the same shape and may be different sizes. Furthermore, the second elastic portion 203 may be equipped with a suction cup, and may be provided with a function to adsorb and hold the outer door 103 when the inner door 106 is opened.
