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 the like are equipped with a signal controller for controlling the lighting of signal lights. An inner door is provided inside the housing of this signal controller to protect the control unit and prevent rain and dust from entering the control unit from the outside.

[0003] For example, Patent Document 1 describes a signal 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] JP 2015-122025 A Summary of the Invention [Problem to be solved by the invention]

[0005] Conventionally, the inner door as in Patent Document 1 has 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 control device is moved for installation or when vehicles pass nearby after installation. However, in such a configuration, the elastic member provided on the main door side is attached to the main door with double-sided tape. This makes it difficult to assemble because there is no positioning, and two parts are required 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 provided on the main body so as to be capable of opening and closing 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, the first door portion having one or more through holes that communicate the first space with the second space in a closed state, an opposing portion provided on the main body and facing the first door portion within the first space when the first door portion is in a closed state, and a second door portion provided on the main body so as to be capable of opening and closing the opening and covering the first door portion in a closed state. The elastic member has a connection portion inserted into the through hole, a first elastic portion connected to one end of the connection portion and having a first opposing surface opposing a first surface which is the surface of the first door portion facing the opposing portion, and being pressed by the opposing portion so that the first opposing surface presses the first surface toward the opposite side to the opposing portion, and a second elastic portion connected to the other end of the connection portion and having a second opposing surface opposing a second surface which is the surface of the first door portion facing the second door portion, and being pressed by the second door portion so that the second opposing surface presses the second surface toward the opposite side to the second door portion.

[0008] According to the above-mentioned controller, the elastic member is provided penetrating 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 one member. This makes it possible to reduce the manufacturing cost and suppress the vibration of the first door portion. In addition, 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 end 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 a periphery of the first door portion. The notched hole may have a limiting portion that limits movement of the inserted connecting portion toward the periphery of the cut-out first door portion.

[0012] The limiting portion may overlap at least a part of the connecting portion when viewed from a peripheral edge side of the first door portion on which 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 which is provided on the main body so as to be able to open and close the internal space and which has one or more through holes that communicate the first space with 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 which 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 which is provided on the main body so as to be able to open and close the opening and which covers the first door unit in the closed state. The elastic member has a connection portion inserted into the through hole, a first elastic portion connected to one end of the connection portion and having a first opposing surface opposing a first surface which is the surface of the first door portion facing the opposing portion, and being pressed by the opposing portion so that the first opposing surface presses the first surface toward the opposite side to the opposing portion, and a second elastic portion connected to the other end of the connection portion and having a second opposing surface opposing a second surface which is the surface of the first door portion facing the second door portion, and being pressed by the second door portion so that the second opposing surface presses the second surface toward the opposite side to the second door portion.

[0015] In order to achieve the above object, an 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 facing a first surface which 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 facing 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. Effect 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 description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

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

[0019] <First embodiment> 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 of the traffic light controllers 100 are attached to a 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 the controller 100 according to the first embodiment of the present invention, FIG. 3 is a perspective view showing the controller 100 with the second door section 103 open, and FIG. 4 is a perspective view showing the controller 100 with the first door section 106 and the second door section 103 open. FIG. 5 is an overall view of the elastic member 200, (A) is a perspective view, and (B) is a front view. FIG. 6 is a view showing the elastic member 200 in communication with the first door section 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, the Y-axis, and the Z-axis indicate three axial directions that are mutually orthogonal, and the X-axis corresponds to the width direction of the controller 100, the Y-axis corresponds to the depth direction of the controller 100, and the Z-axis corresponds 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 has a housing section 101A and an elastic member 200. In this embodiment, the housing section 101A is made of a magnetic material such as an iron plate, has a box shape forming an internal space W for accommodating the control unit 110, and includes a main body 102 having a first opening 107 on one side, a first door section (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 section 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 section (hereinafter referred to as the outer door) 103 as an outer door connected to the main body 102 and provided so as to be able to open and close 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 is approximately rectangular in 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) 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 of the outer door 103, and the 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 as viewed from the Y-axis direction. The outer door 103 is provided with a locking unit 105, and the outer door 103 can be locked with respect 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 in a state where they are stored in a clear file, but the instruction manual TS and the clear file do not have to be provided.

[0026] The facing parts 130 are, for example, L-shaped metal fittings, and in this embodiment, two facing parts 130 are provided along the Z-axis direction. The positions and number of facing parts 130 are the same as the positions and number of elastic members 200 described below. In this embodiment, the facing parts 130 are provided at two locations, one above the other, along the Z-axis direction on the opposite side (the side facing the X-axis direction, the left side as viewed from the Y-axis direction) from the side on which the hinges 108, 106C are provided in the main body 102. The facing parts 130 are attached to the inside of the main body 102 by 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 a 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 capable of opening and closing the inner space W. When the inner door 106 is closed, the inner space W is divided 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 board 106D. The inner door 106 may be made of an iron plate or resin as described above, 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 the elastic member 200 comes into contact around a through hole H, which will be 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, which will be described later. In this embodiment, the first surface 106A and the second surface 106B are formed in 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 from the Y-axis direction, but is not limited to a rectangular shape and may be, for example, a circular shape.

[0032] As shown in FIG. 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 end 106T side of the inner door 106 facing the hinge part 106C. Here, the door end refers to the side opposite to the side (tail side) on which the hinge part 106C is provided of the inner door 106. The positions and number of the through holes H are two, one above the other, on the door end 106T side, similar to the facing 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, etc.) can set and change the lighting times and lighting sequence by operating, for example, the operation panel. In addition to the above basic functions, the control unit 110 may also have a lighting brightness adjustment function and a communication function capable of communicating 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 a manual operation input from a user to control the lighting of the signal light 2. For example, at an event or the like, a user can open the sub door 104 and manually switch the lighting of the signal light 2 on and off 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 connection part 201 inserted into the through hole H, a first elastic part 202 connected to the opposing part 130 side which is one end of the connection part 201, and a second elastic part 203 connected to the outer door 103 side which is the other end of the connection part 201. In this embodiment, the elastic member 200 as a cushioning material that absorbs external vibrations is formed of sponge, but of course is not limited to this and may be, for example, silicone.

[0037] The connection part 201 has a rectangular parallelepiped shape extending in the Y-axis direction when the inner door 106 is in a closed state. In this embodiment, the height Z1 of the connection part 201 (the length along the Z-axis direction when inserted into the through hole H) is longer than the first hole diameter H1 of the through hole H, but of course, this is not limited thereto, and the height Z1 and the first hole diameter H1 may be approximately the same length, or the height Z1 may be shorter than the first hole diameter H1. In this embodiment, the width X1 of the connection part 201 (the length along the X-axis direction when inserted into the through hole H) is longer than the second hole diameter H2 of the through hole H, but of course, this is not limited thereto, and the width X1 and the second hole diameter H2 may be approximately the same length, or the width X1 may be shorter than the second hole 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 facing the first surface 106A, which is the surface on the opposing portion 130 side of the inner door 106, and is pressed by the opposing portion 130, so that the first opposing surface 202A presses (holds) the first surface 106A toward the opposite side to the opposing portion 130. In this embodiment, the first opposing surface 202A is provided on both ends of the connection portion 201 in the height Z1 direction. In addition, the length of the height Z2 on the first opposing surface 202A side of the first elastic portion 202 is formed to be longer than the length of the first hole diameter H1. As a result, when the connection portion 201 of the first elastic portion 202 is inserted into the through hole H, the first opposing surface 202A abuts (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 is, for example, smaller than the contact surface 130A. 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 part 130 and the first abutting surface 202B of the first elastic part 202 come into contact with each other, and when they come into contact, the first elastic part 202 is pressed from the facing part 130 toward the inner door 106. The first facing surface 202A of the pressed first elastic part 202 presses the first surface 106A of the inner door 106.

[0042] 5(B), the shape of the first elastic portion 202 is approximately trapezoidal with a width that narrows from one end side of the connection portion 201 to the first abutment surface 202B. This makes it easier to insert the first elastic portion 202 into the through hole H. Also, in this embodiment, as shown in FIG. 5(A), the width X1 of the connection portion 201 and the width X1 of the first abutment surface 202B are the same, but of course they are not limited to this and may be different.

[0043] The second elastic part 203 has a second opposing surface 203A facing the second surface 106B, which is the surface of the inner door 106 on the outer door 103 side, and is pressed by the outer door 103, so that the second opposing surface 203A presses (holds) the second surface 106B toward the opposite side to the outer door 103. In this embodiment, the second opposing surface 203A is provided on both ends of the connection part 201 in the height Z1 direction. In addition, the length of the height Z3 of the second elastic part 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 connection part 201 of the second elastic part 203 is inserted into the through hole H, the second opposing surface 203A abuts (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. This allows the outer door 103 to be pressed as described above when it is closed. Furthermore, the length Y3 of the second elastic portion 203 and the length Y2 of the first elastic portion 202 may be the same or different. 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 they are in the closed state (the inner door 106 and the outer door 103).

[0044] The second elastic portion 203 further has a second abutment surface 203B that abuts against the outer door surface 103A of the outer door 103 when the inner door 106 is in the closed state. The size of the second abutment surface 203 is not particularly limited, but for example, when the outer door surface 103A is provided separately, it is smaller than the outer door surface 103A. When the outer door surface 103A is provided separately, the second abutment surface 203 may be provided so as to abut against the center part of the outer door surface 103A when the inner door 106 is in the closed state. In this embodiment, the second elastic portion 203 of the elastic member 200 provided on the upper side in the Z-axis direction is pressed by a clear file in which the instruction manual TS and the like are stored. Of course, this is not limited to this, and a clear file in which the instruction manual TS is not stored may be used. When a clear file is not provided, the second elastic portion 203 may abut against the outer door 103 itself in the same manner as the second elastic portion 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 the second surface 106B of the inner door 106.

[0046] 5(B), the shape of the second elastic portion 203 is roughly trapezoidal with a width that narrows from the other end side of the connection 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, in this embodiment, as shown in FIG. 5(A), the width X1 of the connection 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 be elastically deformed 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 is 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 larger than the first hole diameter H1 of the through hole H, so that the first elastic portion 202 is inserted while being elastically deformed. In this embodiment, as shown in FIG. 6, the first elastic portion 202 is inserted into the through hole H while being deformed, but of course, this is not limited thereto, and the second elastic portion 203 may be inserted into the through hole H while being elastically deformed from the first surface 106A side.

[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 the first elastic portion 202 or the second elastic portion 203. 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 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 and 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 can reduce the impact on the inner door 106 when the outer door 103 is closed while the inner door 106 is in a closed state. In other words, by having a gap, the impact is absorbed by the gap when the outer door 103 comes in contact with the second elastic portion 203.

[0050] Furthermore, since 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 slipping 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 slipping 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 a 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 (presses from both sides), thereby making it possible to suppress rattling of the inner door 106 caused by 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, the manufacturing cost can be reduced. 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 end T side. This makes it possible to suppress rattling of the inner door 106 by pressing the door end T side away from the hinge part 106C, which is prone to rattling due to external vibration. This makes it possible to protect the board 106D, if provided on the inner door 106, from vibration.

[0055] Furthermore, rattling can be further suppressed by holding down the top and bottom of inner door 106 with elastic member 200. As a result, in the case where substrate 106D is provided on inner door 106, substrate 106D can be protected from vibration.

[0056] <Modification> 9 shows a modified example of a through hole H' of a first door portion (inner door) 106'. Below, configurations different from the first embodiment will be mainly described, and configurations similar to those in the first embodiment will be given the same reference numerals and descriptions thereof will be omitted or simplified.

[0057] The through hole H' is a cutout 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 cutout hole, is opened on the door end 106T' side as shown in Fig. 9.

[0058] The through hole H' has a first hole HW1 and a second hole HW2 that communicates the first hole HW1 with the door end 106T' (opened) side. The first hole HW1 has a first hole diameter H1, similar to the through hole H of the first embodiment. The hole diameter H1' of the second hole HW2 is shorter than the length of the height Z1. In addition, 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 side of the inner door 106 (the door end 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 side (the door end 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 Fig. 9, the elastic member 200 (connection portion 201) is inserted into the first hole HW1 through the second hole HW2. The connection portion 201 can be elastically deformed so as to be insertable 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 part of the connection portion 201 when viewed from the peripheral edge side (door end 106T' side) of the inner door 106. This makes it possible to prevent the elastic member 200 from moving toward the peripheral edge side and coming loose.

[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 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, this is not limited thereto, 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 body, and a part of it may be made of a non-elastic body.

[0063] In addition, the first elastic part 202 and the second elastic part 203 are punched into a roughly trapezoidal shape, but of course, this is not limited to this, and they may have a three-dimensional shape such as a dumbbell shape. They are also not limited to a trapezoidal shape, and may be hemispherical, cylindrical, or flared toward the opposing part 130 or the outer door 103 side. The first elastic part 202 and the second elastic part 203 are not limited to the same shape, and may be different in size. The second elastic part 203 may also be provided with a suction cup, and may be provided with a function of adsorbing and holding the outer door 103 when the inner door 106 is opened.
