[0050] use Figures 1 to 4 The panel connection structure in the first embodiment will be described.

[0051] Figure 1 This is a transverse cross-sectional view of the elevator car room 1 in the first embodiment. Figure 1 It is a cross-sectional view of the cage wall 2 in the cage room 1. Figure 2 This is a diagram of a main portion of the car wall 2 in the first embodiment. Figure 2 yes Figure 1 Figure A in the figure. Figure 3 This is a diagram of a main portion of the car wall 2 in the first embodiment. Figure 3 yes Figure 2 BB view in the figure. Figure 4This is a diagram of a main portion of the car wall 2 in the first embodiment. Figure 4 yes Figure 2 C-direction view in.

[0052] The elevator car room 1 is raised and lowered in a hoistway. The hoistway is provided across a plurality of floors of a building in which the elevator is provided. The elevator user enters the car room 1 from a certain floor and gets off the car room 1 from another floor.

[0053] The car room 1 has a car floor, a car ceiling, a car wall 2, and a car door. The car floor forms the lower part of the car room 1. The car ceiling forms the upper part of the car room 1. The car wall 2 forms the front, rear, left, and right sides of the car room 1. The car wall 2 on the front side of the car room 1 is provided with a car entrance 3. The car entrance 3 is opened and closed by the car door. The car floor, the car ceiling, the car wall 2, and the car door divide the inside and outside of the car room 1.

[0054] The car wall 2 is formed by a plurality of panels 4. The plurality of panels 4 are arranged between the edge of the car floor and the edge of the car ceiling. The plurality of panels 4 are arranged along the edge of the car floor and the car ceiling. For example, the car wall 2 is placed on the car floor. For example, the car ceiling is placed on the car wall 2.

[0055] The lower part of the panel 4 is connected to the car floor. The upper part of the panel 4 is connected to the car ceiling. The side part of the panel 4 is connected to the adjacent panel 4.

[0056] The plurality of panels 4 include a first panel 5 and a second panel 6 adjacent to each other.

[0057] The first panel 5 includes a first surface plate 5a and a first connecting plate 5b. The first surface plate 5a forms a wall surface in the elevator room 1. The first surface plate 5a extends in the width direction and the height direction of the first panel 5. The first connecting plate 5b extends from the end of the first surface plate 5a on the second panel 6 side in a direction perpendicular to the first surface plate 5a. The first connecting plate 5b extends from the first surface plate 5a to the outside of the elevator room 1. The first connecting plate 5b extends in the thickness direction and the height direction of the first panel 5. The first connecting plate 5b is provided with a first connecting hole 5c.

[0058] The second panel 6 has a second surface plate 6a and a second connecting plate 6b. The second surface plate 6a forms a wall surface in the cage chamber 1. The second surface plate 6a extends in the width direction and the height direction of the second panel 6. The second connecting plate 6b extends from the end of the second surface plate 6a on the first panel 5 side in a direction perpendicular to the second surface plate 6a. The second connecting plate 6b extends from the second surface plate 6a to the outside of the cage chamber 1. The second connecting plate 6b extends in the thickness direction and the height direction of the second panel 6. The second connecting plate 6b is provided with a second connecting hole 6c.

[0059] The outer surface of the first connecting plate 5b overlaps with the outer surface of the second connecting plate 6b. The first connecting hole 5c and the second connecting hole 6c are located on the other end side of the spiral body 7a in the length direction of the spiral body 7a of the torsion coil spring 7 described later. The first connecting hole 5c and the second connecting hole 6c are opposite to each other. For example, the first connecting hole 5c and the second connecting hole 6c have the same shape. For example, the first connecting hole 5c and the second connecting hole 6c are directly opposite to each other.

[0060] The first panel 5 has a torsion coil spring 7 .

[0061] The torsion coil spring 7 has a coil 7a, a fixed arm 7b and a movable arm 7c. The coil 7a, the fixed arm 7b and the movable arm 7c are formed as one body. The coil 7a is located between the fixed arm 7b and the movable arm 7c. The fixed arm 7b extends from one end of the coil 7a. The movable arm 7c extends from the other end of the coil 7a.

[0062] The spiral body 7a is located on the inner side of the first connecting plate 5b. The length direction of the spiral body 7a is toward the extension direction of the first connecting plate 5b. The length direction of the spiral body 7a is toward the horizontal direction. One end of the spiral body 7a is located on the side of the spiral body 7a opposite to the first surface plate 5a. The other end of the spiral body 7a is located on the first surface plate 5a side of the spiral body 7a.

[0063] The fixed arm 7b is located on the inner side of the first connecting plate 5b. The fixed arm 7b is fixed to the first connecting plate 5b. For example, the fixed arm 7b is fixed to the first connecting plate 5b by a stud mounted on the inner surface of the first connecting plate 5b and a nut screwed into the stud. For example, the fixed arm 7b is fixed to the first connecting plate 5b by a countersunk screw passing from the outer side to the inner side of the first connecting plate 5b and a nut screwed into the countersunk screw. The fixed arm 7b is fixed to the first connecting plate 5b at a position lower than the spiral body 7a.

[0064] The movable arm 7c passes through the first connecting hole 5c and the second connecting hole 6c. The movable arm 7c extends from the second connecting hole 6c to the inner side of the second connecting plate 6b, and then extends downward and toward the inner surface of the second connecting plate 6b. The movable arm 7c is pressed against the inner surface of the second connecting plate 6b by the restoring force of the torsion coil spring 7. The movable arm 7c is pressed against the inner surface of the second connecting plate 6b at a position lower than the spiral body 7a.

[0065] The fixing portion of the first connecting plate 5b fixing the fixed arm 7b and the movable arm 7c are arranged in the thickness direction of the second connecting plate 6b. The fixing portion of the first connecting plate 5b fixing the fixed arm 7b and the movable arm 7c sandwich the second connecting plate 6b.

[0066] Here, the movable arm 7c can rotate by the torsion of the torsion coil spring 7 and move in the up-down direction outside the first connecting plate 5b. When the movable arm 7c moves upward outside the first connecting plate 5b, the spiral body 7a is wound up, and the restoring force of the torsion coil spring 7 increases. When the movable arm 7c moves downward outside the first connecting plate 5b, the spiral body 7a is loosened, and the restoring force of the torsion coil spring 7 decreases.

[0067] That is, when the torsion coil spring 7 is arranged as described above, the side of the movable arm 7c that winds up the spiral body 7a is at the top, and the side of the movable arm 7c that unwinds the spiral body 7a is at the bottom.

[0068] In addition, when the first panel 5 and the second panel 6 are separated, the movable arm 7c extends to the outside of the first connecting plate 5b through the first connecting hole 5c, and then extends downward and toward the outer surface of the first connecting plate 5b. The gap between the movable arm 7c and the outer surface of the first connecting plate 5b is smaller than the thickness of the second connecting plate 6b. For example, the movable arm 7c is pressed against the outer surface of the first connecting plate 5b.

[0069] In addition, from the state where the first panel 5 and the second panel 6 are separated, the movable arm 7c can be inserted through the second connection hole 6c.

[0070] Furthermore, the outer surface of the first connecting plate 5b and the outer surface of the second connecting plate 6b can overlap with each other.

[0071] When the first panel 5 moves downward relative to the second panel 6 , the movable arm 7 c can climb onto the inner surface of the second connecting plate 6 b and be pressed against the inner surface of the second connecting plate 6 b by the restoring force of the torsion coil spring 7 .

[0072] The panel connection structure in the first embodiment is configured as described above, and connects the first panel 5 and the second panel 6 .

[0073] The panel connection structure in the first embodiment is a panel connection structure that connects the first panel 5 and the second panel 6, the first panel 5 has a first connection plate 5b, the second panel 6 has a second connection plate 6b, the first connection plate 5b is provided with a first connection hole 5c, the second connection plate 6b is provided with a second connection hole 6c, the outer surface of the first connection plate 5b coincides with the outer surface of the second connection plate 6b, and the first connection hole 5c is opposite to the second connection hole 6c, the first panel 5 has a torsion coil spring 7, the torsion coil spring 7 has a spiral body 7a, a fixed arm 7b extending from one end of the spiral body 7a, and a movable arm 7c extending from the other end of the spiral body 7a, and the spiral body 7a is located at the first On the inner side of a connecting plate 5b, the length direction of the spiral body 7a is toward the extension direction of the first connecting plate 5b, the fixed arm 7b is located on the inner side of the first connecting plate 5b and is fixed, the movable arm 7c passes through the first connecting hole 5c and the second connecting hole 6c and is pressed against the inner surface of the second connecting plate 6b by the restoring force of the torsion coil spring 7, wherein, when the first panel 5 and the second panel 6 are separated, the movable arm 7c passes through the first connecting hole 5c and extends to the outside of the first connecting plate 5b, and then extends toward the side of the loosened spiral body 7a and the outer surface of the first connecting plate 5b, and the gap between the movable arm 7c and the outer surface of the first connecting plate 5b is smaller than the thickness of the second connecting plate 6b.

[0074] Thus, even if the thickness of at least one of the first connection plate 5 b and the second connection plate 6 b that overlap when connecting the first panel 5 and the second panel 6 varies, the first panel 5 and the second panel 6 can be connected.

[0075] In the panel connection structure of embodiment 1, from the state where the first panel 5 and the second panel 6 are separated, the movable arm 7c can pass through the second connection hole 6c, and the outer surface of the first connection plate 5b and the outer surface of the second connection plate 6b can overlap, and when the first panel 5 moves relative to the second panel 6 toward the side of the unwinding spiral 7a of the movable arm 7c, the movable arm 7c can climb onto the inner surface of the second connection plate 6b and be pressed against the inner surface of the second connection plate 6b by the restoring force of the torsion coil spring 7.

[0076] Thereby, the movable arm 7c can be easily pressed against the inner surface of the second connecting plate 6b.

[0077] In addition, the first panel 5 and the second panel 6 can be connected from a desired side. For example, the first panel 5 and the second panel 6 can be connected from the car room 1.

[0078] In the panel connection structure of the first embodiment, the fixed arm 7b is fixed to the first connection plate 5b, and the fixing portion of the first connection plate 5b that fixes the fixed arm 7b and the movable arm 7c sandwich the second connection plate 6b in the thickness direction of the second connection plate 6b.

[0079] Thereby, the first panel 5 and the second panel 6 can be connected more firmly.

[0080] Furthermore, since the deflection generated in the first connection plate 5b and the second connection plate 6b is suppressed by the restoring force of the torsion coil spring 7, it is possible to make it difficult for a gap to be generated between the first connection plate 5b and the second connection plate 6b.

[0081] Next, use Figure 5 and Figure 6 A method for connecting panels according to the first embodiment will be described.

[0082] Figure 5 This is a flowchart showing a panel connection method in the first embodiment. Figure 6 This is a diagram showing a method of connecting panels in the first embodiment. Figure 6 is with Figure 3 The corresponding figure. Figure 6 (a) means Figure 5 FIG. 1 is a diagram of step S11 in FIG. Figure 6 (b) means Figure 5 FIG. 1 is a diagram of step S12 in FIG. Figure 6 (c) means Figure 5 FIG. 1 is a diagram of step S13 in FIG. Figure 6 In (c), the movement of the movable arm 7c is indicated by a two-dot chain line. Figure 6 (d) means Figure 5 FIG. 1 is a diagram of step S14 in FIG.

[0083] The panel connection method in the first embodiment includes: Figure 5 The steps shown in S11 to S14.

[0084] In step S11 (movable arm insertion step), the movable arm 7 c is inserted into the second connection hole 6 c from a state where the first panel 5 and the second panel 6 are separated.

[0085] At this time, the first panel 5 is located above the second panel 6. In addition, the second panel 6 is previously attached to the attachment position of the car floor.

[0086] In step S12 (connecting plate overlapping step), the outer surface of the first connecting plate 5b and the outer surface of the second connecting plate 6b are overlapped.

[0087] At this time, the first panel 5 is located above the second panel 6 .

[0088] In step S13 (movable arm pressing step), the first panel 5 is moved downward to allow the movable arm 7c to climb onto the inner surface of the second connecting plate 6b and be pressed against the inner surface of the second connecting plate 6b by the restoring force of the torsion coil spring 7.

[0089] When the first panel 5 is moved downward in a state where the outer surface of the first connection plate 5b and the outer surface of the second connection plate 6b are overlapped, the movable arm 7c climbs onto the inner surface of the second connection plate 6b.

[0090] Thus, the movable arm 7 c is pressed against the inner surface of the second connecting plate 6 b by the restoring force of the torsion coil spring 7 .

[0091] At this time, the first panel 5 is located above the second panel 6 .

[0092] In step S14 (connecting plate positioning step), the first panel 5 is moved downward to align the position of the first connecting plate 5 b with the position of the second connecting plate 6 b .

[0093] The first panel 5 is moved downward while the outer surface of the first connecting plate 5b overlaps the outer surface of the second connecting plate 6b, thereby aligning the height direction of the first connecting plate 5b with the second connecting plate 6b. When the first panel 5 is moved, the movable arm 7c moves along the inner surface of the second connecting plate 6b.

[0094] If the first connecting plate 5b and the second connecting plate 6b are misaligned in width direction, the first panel 5 is moved in the thickness direction to align the first connecting plate 5b and the second connecting plate 6b in width direction.

[0095] Thereby, the movable arm 7c is pressed against the inner surface of the second connecting plate 6b, and the first panel 5 is attached to the attachment position of the car floor.

[0096] The panel connecting method in the first embodiment is performed as described above, and the first panel 5 and the second panel 6 are connected.

[0097] The panel connecting method in embodiment 1 includes: step S11 of passing the movable arm 7c through the second connecting hole 6c from the state where the first panel 5 and the second panel 6 are separated; and step S13 of pressing the movable arm 7c against the inner surface of the second connecting plate 6b by the restoring force of the torsion coil spring 7.

[0098] Thus, even if the thickness of at least one of the first connection plate 5 b and the second connection plate 6 b that overlap when connecting the first panel 5 and the second panel 6 varies, the first panel 5 and the second panel 6 can be connected.

[0099] The panel connecting method in embodiment 1 includes: step S11 of passing the movable arm 7c through the second connecting hole 6c from a state where the first panel and the second panel 6 are separated; step S12 of making the outer surface of the first connecting plate 5b overlap with the outer surface of the second connecting plate 6b; and step S13 of moving the first panel 5 downward so that the movable arm 7c climbs onto the inner surface of the second connecting plate 6b and presses against the inner surface of the second connecting plate 6b using the restoring force of the torsion coil spring 7.

[0100] Thereby, the movable arm 7c can be easily pressed against the inner surface of the second connecting plate 6b.

[0101] In addition, the first panel 5 can be connected to the second panel 6 from a desired side. For example, the first panel 5 and the second panel 6 can be connected from the car room 1.

[0102] In the first embodiment, the first connection hole 5c, the second connection hole 6c, and the torsion coil spring 7 may be configured to be reversed in the width direction of the first connection plate 5b and the second connection plate 6b.

[0103] In Embodiment 1, the first connection hole 5c, the second connection hole 6c, and the torsion coil spring 7 may be configured to be reversed in the vertical direction. In this case, for example, the panel connection method is as follows.

[0104] When the first panel 5 and the second panel 6 are connected, the first panel 5 is previously mounted at the mounting position of the car floor in step S11, and the second panel 6 is moved in steps S11 to S14.

[0105] In Embodiment 1, the first connection hole 5c, the second connection hole 6c, and the torsion coil spring 7 may be rotated along the first connection plate 5b and the second connection plate 6b so that the length direction of the spiral body 7a is oriented in the vertical direction. In this case, for example, the panel connection structure and connection method are as follows.

[0106] The movable arm 7c extends from the second connecting hole 6c to the inner side of the second connecting plate 6b, and further extends in the width direction of the second connecting plate 6b toward the side opposite to the second surface plate 6a and the inner surface of the second connecting plate 6b. The movable arm 7c is pressed against the inner surface of the second connecting plate 6b by the restoring force of the torsion coil spring 7.

[0107] The movable arm 7c can rotate by the torsion of the torsion coil spring 7 and move in the horizontal direction inside the second connecting plate 6b. When the movable arm 7c moves to the first surface plate 5a side in the width direction of the first connecting plate 5b outside the first connecting plate 5b, the spiral body 7a is wound tightly, and the restoring force of the torsion coil spring 7 increases. When the movable arm 7c moves to the side opposite to the first surface plate 5a in the width direction of the first connecting plate 5b outside the first connecting plate 5b, the spiral body 7a is loosened, and the restoring force of the torsion coil spring 7 decreases.

[0108] When the first panel 5 and the second panel 6 are connected, the second panel 6 is previously mounted at the mounting position of the car floor in step S11, and the first panel 5 is moved in steps S11 to S14.

[0109] In the first embodiment, the first panel 5 and the second panel 6 may be integrally formed and reversed in the width direction of the first panel 5 and the second panel 6 .

[0110] In addition, in embodiment 1, by utilizing the first connecting hole 5c, the second connecting hole 6c and the torsion coil spring 7 to connect the first connecting plate 5b and the second connecting plate 6b at multiple locations, the first connecting plate 5b and the second connecting plate 6b can be prevented from being misaligned, and the first panel 5 and the second panel 6 can be connected more firmly.

[0111] Furthermore, the connection structure and the connection method of the first embodiment can be used for two panels 4 adjacent to each other at the corner of the car wall 2 .

[0112] In this case, the first connection hole 5c and the torsion coil spring 7 are provided in the first surface plate 5a, or the second connection hole 6c is provided in the second surface plate 6a.

[0113] Next, use Figures 7 to 11 The panel connection structure according to the second embodiment will be described.

Figure 8 This is a diagram of a main portion of a car wall 2 in the second embodiment. Figure 8 is with Figure 4 The corresponding figure.

[0115] The panel connection structure in the second embodiment is different from the panel connection structure in the first embodiment as follows.

[0116] The first connection plate 5b is provided with first connection holes 5d replacing the first connection holes 5c of the connection structure of the panel in Embodiment 1. The second connection plate 6b is provided with second connection holes 6d replacing the second connection holes 6c of the connection structure of the panel in Embodiment 1.

[0117] The first connecting hole 5d and the second connecting hole 6d are located at the other end side of the spiral body 7a in the length direction of the spiral body 7a. The first connecting hole 5d and the second connecting hole 6d are opposite to each other. For example, the first connecting hole 5d and the second connecting hole 6d are of the same shape. For example, the first connecting hole 5d and the second connecting hole 6d are directly opposite to each other.

[0118] The first connecting hole 5d and the second connecting hole 6d are long holes, and are formed as follows.

[0119] The length direction of the long hole is oriented in a direction of twisting relative to the length direction of the spiral body 7a. The length direction of the spiral body 7a is oriented in the horizontal direction, whereas the length direction of the long hole is oriented in the up-down direction. The restoring force of the torsion coil spring 7 when the movable arm 7c is located at one end side of the length direction of the long hole is greater than the restoring force of the torsion coil spring 7 when the movable arm 7c is located at the other end side of the length direction of the long hole. The width of one end side of the length direction of the long hole is greater than the width of the other end side of the length direction of the long hole. One end side of the length direction of the long hole becomes the upper side of the long hole. The other end side of the length direction of the long hole becomes the lower side of the long hole.

[0120] When the movable arm 7c is rotated upward in a state where the first panel 5 and the second panel 6 are separated, the movable arm 7c can pass through the first connecting hole 5d and be stored inside the outer surface of the first connecting plate 5b.

[0121] Moreover, the first connecting hole 5d and the second connecting hole 6d are opposite to each other, and when the movable arm 7c is released, the movable arm 7c can pass through the first connecting hole 5d and the second connecting hole 6d and be pressed against the inner surface of the second connecting plate 6b by the restoring force of the torsion coil spring 7.

[0122] When the outer surface of the first connecting plate 5 b overlaps with the outer surface of the second connecting plate 6 b , the movable arm 7 c can move along the inner surface of the second connecting plate 6 b by the restoring force of the torsion coil spring 7 .

[0123] In addition, the movable arm 7c is held by the stopper plate 8 at a position inside the outer surface of the first connecting plate 5b as described below, and can be released.

[0124] When the movable arm 7c is stored in a position closer to the inside than the outer surface of the first connecting plate 5b, one end side of the stop plate 8 can pass through the first connecting hole 5d and abut against a portion of the inner surface of the first connecting plate 5b that is closer to the first surface plate 5a than the first connecting hole 5d and a portion of the outer surface of the first connecting plate 5b that is closer to the first surface plate 5a than the first connecting hole 5d, thereby crossing the first connecting hole 5d.

[0125] Furthermore, the other end side of the stopper plate 8 can be fixed to the outside of the first panel 5. For example, the other end side of the stopper plate 8 is fixed to the outer surface of the first connecting plate 5b by the adhesive tape 9. For example, the other end side of the stopper plate 8 protrudes to the outside of the first surface plate 5a side of the first panel 5.

[0126] Furthermore, the movable arm 7 c is pressed against the stopper plate 8 by the restoring force of the torsion coil spring 7 , whereby the movable arm 7 c can be held at a position further inside than the outer surface of the first connecting plate 5 b .

[0127] Furthermore, by separating the other end of the stopper plate 8 from the first panel 5 and taking one end of the stopper plate 8 out of the first connection hole 5d to the outside of the first connection plate 5b, the stopper plate 8 is disengaged from the first connection hole 5d, and the movable arm 7c can be released. Furthermore, the stopper plate 8 can be taken into the car chamber 1 from the gap between the first connection plate 5b and the second connection plate 6b.

[0128] The panel connection structure in the second embodiment is configured as described above, and connects the first panel 5 and the second panel 6 .

[0129] In the panel connection structure of embodiment 2, when the movable arm 7c is rotated toward the side of the winding spiral 7a when the first panel 5 and the second panel 6 are separated, the movable arm 7c can pass through the first connection hole 5d and be stored at a position closer to the inside than the outer surface of the first connection plate 5b.

[0130] This can prevent the movable arm 7c from hitting surrounding objects and being damaged when the first panel 5 is moved. In other words, the space required for moving the first panel 5 can be reduced.

[0131] In the panel connection structure of embodiment 2, when the first panel 5 and the second panel 6 are separated, the movable arm 7c is stored in a position closer to the inside than the outer surface of the first connecting plate 5b, and the first connecting hole 5d is opposite to the second connecting hole 6d. Moreover, when the movable arm 7c is released, the movable arm 7c can pass through the first connecting hole 5d and the second connecting hole 6d and be pressed against the inner surface of the second connecting plate 6b through the restoring force of the torsion coil spring 7.

[0132] Thereby, the movable arm 7c can be easily pressed against the inner surface of the second connecting plate 6b.

[0133] In addition, the first panel 5 and the second panel 6 can be connected from a desired side. For example, the first panel 5 and the second panel 6 can be connected from the car room 1.

[0134] In the connection structure of the panel of embodiment 2, the first connection hole 5d and the second connection hole 6d are long holes, and the length direction of the long hole is toward the direction of twisting relative to the length direction of the spiral body 7a. When the movable arm 7c is located at one end side of the long hole, the restoring force of the torsion coil spring 7 is greater than the restoring force of the torsion coil spring 7 when the movable arm 7c is located at the other end side of the long hole, and the width of one end side of the long hole in the length direction is greater than the width of the other end side of the long hole in the length direction.

[0135] Thereby, the movable arm 7c can be easily stored in the inner side than the outer surface of the first connecting plate 5b.

[0136] In addition, when the first connecting hole 5d and the second connecting hole 6d are made opposite to each other, the movable arm 7c can be easily passed through the first connecting hole 5d and the second connecting hole 6d even if the first connecting hole 5d and the second connecting hole 6d are offset in the width direction of the first connecting hole 5d and the second connecting hole 6d.

[0137] Furthermore, by making the width of the long hole larger toward one end of the long hole and smaller toward the other end of the long hole, the movable arm 7c can smoothly move in the longitudinal direction of the long hole.

[0138] In the panel connection structure of embodiment 2, the first panel 5 has a first surface plate 5a, and the first connecting plate 5b extends from the end of the first surface plate 5a in a direction perpendicular to the first surface plate 5a. When the movable arm 7c is stored in a position closer to the inside than the outer surface of the first connecting plate 5b, one end side of the stop plate 8 can pass through the first connecting hole 5c and abut against a portion of the inner surface of the first connecting plate 5b that is closer to the first surface plate 5a than the first connecting hole 5c and a portion of the outer surface of the first connecting plate 5b that is closer to the first surface plate 5a than the first connecting hole 5c, thereby crossing the first connecting hole 5c, and the other end side of the stop plate 8 can be fixed to the outside of the first panel 5, and the movable arm 7c is pressed against the stop plate 8 by the restoring force of the torsion coil spring 7, thereby the movable arm 7c can be maintained at a position closer to the inside than the outer surface of the first connecting plate 5b.

[0139] Thereby, the movable arm 7c can be easily held at a position inside the outer surface of the first connecting plate 5b.

[0140] Next, use Fig.12 and Fig.13 A method of connecting panels in the second embodiment will be described.

[0141] Fig.12 This is a flowchart showing a panel connection method in the second embodiment. Fig.13 This is a diagram showing a method of connecting panels in the second embodiment. Fig.13 is with Figure 7 as well as Fig.10 The corresponding figure. Fig.13 (a) means Fig.12 FIG. 5 is a diagram of step S21 in FIG. Fig.13 (b) means Fig.12 FIG. 5 is a diagram of step S22 in FIG. Fig.13 (c) means Fig.12 FIG. 5 is a diagram of step S23 in FIG. Fig.13 (d) means Fig.12 FIG. 1 is a diagram of step S24 in FIG. Fig.13 (c) and Fig.13 In (d), the movement of the movable arm 7c is indicated by a two-dot chain line.

[0142] The panel connection method in the second embodiment includes: Fig.12 The steps shown in S21 to S24.

[0143] In step S21 (movable arm storing step), the movable arm 7 c is stored at a position inside the outer surface of the first connecting plate 5 b in a state where the first panel 5 and the second panel 6 are separated.

[0144] By rotating the movable arm 7c upward, the movable arm 7c is passed through the first connection hole 5d and stored inside the outer surface of the first connection plate 5b.

[0145] The movable arm 7c is held by the stopper plate 8 at a position inside the outer surface of the first connection plate 5b as described below.

[0146] When the movable arm 7c is stored in a position closer to the inside than the outer surface of the first connecting plate 5b, one end side of the stop plate 8 is passed through the first connecting hole 5d, and abuts against a portion of the inner surface of the first connecting plate 5b that is closer to the first surface plate 5a than the first connecting hole 5d, and a portion of the outer surface of the first connecting plate 5b that is closer to the first surface plate 5a than the first connecting hole 5d, thereby crossing the first connecting hole 5d.

[0147] Furthermore, the other end side of the stopper plate 8 is fixed to the outside of the first panel 5. For example, the other end side of the stopper plate 8 is fixed to the outer surface of the first connecting plate 5b using an adhesive tape 9. For example, the other end side of the stopper plate 8 protrudes to the outside of the first surface plate 5a side of the first panel 5.

[0148] Furthermore, the movable arm 7 c is pressed against the stopper plate 8 by the restoring force of the torsion coil spring 7 , thereby holding the movable arm 7 c at a position further inside than the outer surface of the first connection plate 5 b .

[0149] In step S22 (connection hole alignment step), the first connection hole 5d and the second connection hole 6d are made to face each other.

[0150] In addition, the second panel 6 is installed in advance at the installation position of the car floor. In addition, a gap is left between the outer surface of the first connecting plate 5b and the outer surface of the second connecting plate 6b so that the stopper plate 8 can be taken into the car room 1 in step S23.

[0151] In step S23 (movable arm pressing step), the movable arm 7c is released, and the movable arm 7c is passed through the first connection hole 5d and the second connection hole 6d by the restoring force of the torsion coil spring 7 to be pressed against the inner surface of the second connection plate 6b.

[0152] In addition, the movable arm 7c is released as follows.

[0153] The other end of the stopper plate 8 is separated from the first panel 5, and one end of the stopper plate 8 is taken out from the first connecting hole 5d to the outside of the first connecting plate 5b, thereby disengaging the stopper plate 8 from the first connecting hole 5d and releasing the movable arm 7c. Then, the stopper plate 8 is taken into the car chamber 1 from the gap between the first connecting plate 5b and the second connecting plate 6b.

[0154] In step S24 (connecting plate overlap step), the outer surface of the first connecting plate 5b is overlapped with the outer surface of the second connecting plate 6b, the movable arm 7c is pressed against the inner surface of the second connecting plate 6b by the restoring force of the torsion coil spring 7, and the position of the first connecting plate 5b is aligned with the position of the second connecting plate 6b.

[0155] When the outer surface of the first connecting plate 5 b is overlapped with the outer surface of the second connecting plate 6 b , the movable arm 7 c moves along the inner surface of the second connecting plate 6 b by the restoring force of the torsion coil spring 7 .

[0156] If the first connecting plate 5b and the second connecting plate 6b are misaligned in width direction, the first panel 5 is moved in the thickness direction to align the first connecting plate 5b and the second connecting plate 6b in width direction.

[0157] Thereby, the movable arm 7c is pressed against the inner surface of the second connecting plate 6b, and the first panel 5 is attached to the attachment position of the car floor.

[0158] The panel connecting method in the second embodiment is performed as described above, and the first panel 5 and the second panel 6 are connected.

[0159] The panel connecting method in embodiment 2 includes: step S23 of passing the movable arm 7c through the second connecting hole 6d from the state where the first panel 5 and the second panel 6 are separated; and step S23 of pressing the movable arm 7c against the inner surface of the second connecting plate 6b by the restoring force of the torsion coil spring 7.

[0160] Thus, even if the thickness of at least one of the first connection plate 5 b and the second connection plate 6 b that overlap when connecting the first panel 5 and the second panel 6 varies, the first panel 5 and the second panel 6 can be connected.

[0161] The panel connecting method in embodiment 2 includes: step S21, when the first panel 5 and the second panel 6 are separated, the movable arm 7c is stored in a position closer to the inside than the outer surface of the first connecting plate 5b; step S22, the first connecting hole 5d and the second connecting hole 6d are made opposite to each other; and step S23, the movable arm 7c is released, and the restoring force of the torsion coil spring 7 is used to make the movable arm 7c pass through the first connecting hole 5d and the second connecting hole 6d and press it against the inner surface of the second connecting plate 6b.

[0162] Thereby, the movable arm 7c can be easily pressed against the inner surface of the second connecting plate 6b.

[0163] In addition, the first panel 5 can be connected to the second panel 6 from a desired side. For example, the first panel 5 and the second panel 6 can be connected from the car room 1.

[0164] In addition, when the first panel 5 is moved, the movable arm 7c can be prevented from hitting surrounding objects and being damaged. In other words, the space required for moving the first panel 5 can be reduced.

[0165] In the second embodiment, the movable arm 7c is held by the stopper plate 8 at a position inside the outer surface of the first connecting plate 5b and is releasable as described below.

[0166] When the movable arm 7c is stored in a position closer to the inside than the outer surface of the first connecting plate 5b, one end side of the stop plate 8 can pass through the first connecting hole 5d, abut against a portion of the inner surface of the first connecting plate 5b closer to one side than the first connecting hole 5d and a portion of the outer surface of the first connecting plate 5b closer to the other side than the first connecting hole 5d, thereby crossing the first connecting hole 5d.

[0167] Furthermore, the other end side of the stopper plate 8 can be fixed to the outside of the first panel 5. For example, the other end side of the stopper plate 8 is fixed to the outer surface of the first connecting plate 5b by the adhesive tape 9. For example, the other end side of the stopper plate 8 protrudes to the outside of the first surface plate 5a side of the first panel 5.

[0168] Furthermore, the movable arm 7 c is pressed against the stopper plate 8 by the restoring force of the torsion coil spring 7 , whereby the movable arm 7 c can be held at a position further inside than the outer surface of the first connecting plate 5 b .

[0169] Furthermore, by separating the other end of the stopper plate 8 from the first panel 5 and taking one end of the stopper plate 8 out of the first connection hole 5d to the outside of the first connection plate 5b, the stopper plate 8 is disengaged from the first connection hole 5d, and the movable arm 7c can be released. Furthermore, the stopper plate 8 can be taken into the car chamber 1 from the gap between the first connection plate 5b and the second connection plate 6b.

[0170] Furthermore, in the second embodiment, the first panel 5 may be mounted in advance at the mounting position of the car floor in step S22 , and the second panel 6 may be moved in steps S22 to S24 .

[0171] In the second embodiment, the first connection hole 5d, the second connection hole 6d, and the torsion coil spring 7 may be configured to be reversed in the width direction of the first connection plate 5b and the second connection plate 6b.

[0172] In the second embodiment, the first connection hole 5d, the second connection hole 6d, and the torsion coil spring 7 may be configured to be reversed in the vertical direction.

[0173] In the second embodiment, the first connection hole 5d, the second connection hole 6d, and the torsion coil spring 7 may be rotated along the first connection plate 5b and the second connection plate 6b so that the longitudinal direction of the coil 7a faces the vertical direction.

[0174] In the second embodiment, the first panel 5 and the second panel 6 may be integrally formed and reversed in the width direction of the first panel 5 and the second panel 6 .

[0175] In addition, in embodiment 2, by utilizing the first connecting hole 5d, the second connecting hole 6d and the torsion coil spring 7 to connect the first connecting plate 5b and the second connecting plate 6b at multiple locations, the first connecting plate 5b and the second connecting plate 6b can be prevented from being misaligned, and the first panel 5 and the second panel 6 can be connected more firmly.

[0176] Furthermore, the connection structure and the connection method of the second embodiment can be used for two panels 4 adjacent to each other at the corner of the car wall 2 .

[0177] Next, use Figures 14 to 16 A panel connection structure in a first modified example of the second embodiment will be described.

[0178] Fig.14 It is a figure which shows the attachment state of the stopper plate 10 in the 1st modification of Embodiment 2. Fig.14 yes Fig.15 The JJ view in the figure. Fig.14 is with Fig. 9 The corresponding figure. Fig.15 It is a figure which shows the attachment state of the stopper plate 10 in the 1st modification of Embodiment 2. Fig.15 yes Fig.14 The GG view in the figure. Fig.15 is with Fig.10 The corresponding figure. Fig.16 It is a figure which shows the attachment state of the stopper plate 10 in the 1st modification of Embodiment 2. Fig.16 yes Fig.14 H view in the figure. Fig.16 is with Fig.11 The corresponding figure.

[0179] The panel connection structure in the first modified example of the second embodiment is different from the panel connection structure in the second embodiment as follows.

[0180] The movable arm 7c is held at a position inside the outer surface of the first connection plate 5b by a stopper plate 10 replacing the stopper plate 8 of the panel connection structure in the second embodiment, and is releasable.

[0181] When the movable arm 7c is stored in a position closer to the inside than the outer surface of the first connecting plate 5b, one end side of the stop plate 10 can pass through the outer side of the first panel 5 on the opposite side of the first surface plate 5a, and abut against a portion of the inner surface of the first connecting plate 5b that is closer to the opposite side of the first surface plate 5a than the first connecting hole 5d, and a portion of the inner surface of the first connecting plate 5b that is closer to the first surface plate 5a than the first connecting hole 5d, thereby crossing the first connecting hole 5d.

[0182] For example, the first panel 5 is provided with a stop plate mounting hole 5e on the side opposite to the first surface plate 5a than the first connecting hole 5d. The stop plate mounting hole 5e connects the outer side and the inner side of the first panel 5 on the side opposite to the first surface plate 5a, and can insert and remove one end side of the stop plate 10 along the width direction of the first connecting plate 5b.

[0183] The other end of the stopper plate 10 can be opposed to the outer surface of the first connecting plate 5 b . For example, the other end of the stopper plate 10 protrudes outward on the first surface plate 5 a side of the first panel 5 .

[0184] Furthermore, the movable arm 7 c is pressed against the stopper plate 10 by the restoring force of the torsion coil spring 7 , whereby the movable arm 7 c can be held at a position further inside than the outer surface of the first connecting plate 5 b .

[0185] Furthermore, by taking out one end side of the stopper plate 10 to the outside of the first panel 5 on the side opposite to the first surface plate 5a, the stopper plate 10 is disengaged from the first connecting hole 5d, and the movable arm 7c can be released. Furthermore, the stopper plate 10 can be taken into the car room 1 from the gap between the first connecting plate 5b and the second connecting plate 6b.

[0186] The panel connection structure in the first modified example of the second embodiment is configured as described above, and connects the first panel 5 and the second panel 6 .

[0187] In the panel connection structure of the first variant of embodiment 2, the first panel 5 has a first surface plate 5a, and the first connecting plate 5b extends from the end of the first surface plate 5a to a direction perpendicular to the first surface plate 5a. When the movable arm 7c is stored in a position closer to the inside than the outer surface of the first connecting plate 5b, one end side of the stop plate 10 can pass through the outer side of the first panel 5 on the side opposite to the first surface plate 5a, and abut against a portion of the inner surface of the first connecting plate 5b on the opposite side of the first surface plate 5a than the first connecting hole 5d and a portion of the inner surface of the first connecting plate 5b on the first surface plate 5a side than the first connecting hole 5d, thereby crossing the first connecting hole 5d, and the other end side of the stop plate 10 can be opposite to the outer surface of the first connecting plate 5b, and the movable arm 7c is pressed against the stop plate 10 by the restoring force of the torsion coil spring 7, thereby the movable arm 7c can be maintained at a position closer to the inside than the outer surface of the first connecting plate 5b.

[0188] Thereby, the movable arm 7c can be easily held at a position inside the outer surface of the first connecting plate 5b.

[0189] In the first modified example of the second embodiment, the movable arm 7c is held by the stopper plate 10 at a position inside the outer surface of the first connecting plate 5b and is releasable as described below.

[0190] When the movable arm 7c is stored in a position closer to the inside than the outer surface of the first connecting plate 5b, one end side of the stop plate 10 can pass through the outer side of the first panel on the opposite side of the first surface plate 5a, and abut against a portion of the inner surface of the first connecting plate 5b closer to one side than the first connecting hole 5d and a portion of the inner surface of the first connecting plate 5b closer to the other side than the first connecting hole 5d, thereby crossing the first connecting hole 5d.

[0191] The other end of the stopper plate 10 can be opposed to the outer surface of the first connecting plate 5 b . For example, the other end of the stopper plate 10 protrudes outward on the first surface plate 5 a side of the first panel 5 .

[0192] Furthermore, the movable arm 7 c is pressed against the stopper plate 10 by the restoring force of the torsion coil spring 7 , whereby the movable arm 7 c can be held at a position further inside than the outer surface of the first connecting plate 5 b .

[0193] Furthermore, by taking out one end side of the stopper plate 10 to the outside of the first panel 5 on the side opposite to the first surface plate 5a, the stopper plate 10 is disengaged from the first connecting hole 5d, and the movable arm 7c can be released. Furthermore, the stopper plate 10 can be taken into the car room 1 from the gap between the first connecting plate 5b and the second connecting plate 6b.

[0194] Next, use Figures 17 to 20The panel connection structure according to the third embodiment will be described.

[0195] Fig.17 This is a diagram showing a main portion of a car wall 2 in the third embodiment. Fig.17 is with Figure 2 The corresponding figure. Fig.18 This is a diagram showing a main portion of a car wall 2 in the third embodiment. Fig.18 yes Fig.17 KK view in the figure. Fig.18 is with Figure 3 The corresponding figure. Fig.19 This is a diagram showing a main portion of a car wall 2 in the third embodiment. Fig.19 yes Fig.17 LL view in the figure. Fig.19 In FIG. 1 , the helical body 7a is indicated by a double-dashed line. Fig. 20 This is a diagram showing a main portion of a car wall 2 in the third embodiment. Fig. 20 yes Fig.17 M-direction view in . Fig. 20 is with Figure 4 The corresponding figure.

[0196] The panel connection structure in the third embodiment is different from the panel connection structure in the first embodiment as follows.

[0197] The first connecting plate 5b is provided with a first sub-connecting hole 5f and a first intermediate connecting hole 5g in addition to the first connecting hole 5c of the connecting structure of the panel in Embodiment 1. The second connecting plate 6b is provided with a second sub-connecting hole 6f and a second intermediate connecting hole 6g in addition to the second connecting hole 6c of the connecting structure of the panel in Embodiment 1.

[0198] The first auxiliary connecting hole 5f and the second auxiliary connecting hole 6f are located at one end side of the spiral body 7a in the length direction of the spiral body 7a. The first auxiliary connecting hole 5f and the second auxiliary connecting hole 6f are opposite to each other. For example, the first auxiliary connecting hole 5f and the second auxiliary connecting hole 6f have the same shape. For example, the first auxiliary connecting hole 5f and the second auxiliary connecting hole 6f are directly opposite to each other.

[0199] The first intermediate connecting hole 5g is connected to the first connecting hole 5c and the first auxiliary connecting hole 5f. The second intermediate connecting hole 6g is connected to the second connecting hole 6c and the second auxiliary connecting hole 6f. The first intermediate connecting hole 5g and the second intermediate connecting hole 6g extend in the length direction of the spiral body 7a. For example, the first intermediate connecting hole 5g and the second intermediate connecting hole 6g extend in parallel with the length direction of the spiral body 7a. The first intermediate connecting hole 5g is opposite to the second intermediate connecting hole 6g. For example, the first intermediate connecting hole 5g and the second intermediate connecting hole 6g are the same shape. For example, the first intermediate connecting hole 5g and the second intermediate connecting hole 6g are directly opposite.

[0200] The torsion coil spring 7 has a sub-movable arm 7d and an intermediate movable arm 7e in addition to the coil body 7a, the fixed arm 7b and the movable arm 7c of the panel connection structure in the first embodiment. The movable arm 7c, the sub-movable arm 7d and the intermediate movable arm 7e are formed as one body. The intermediate movable arm 7e is located between the movable arm 7c and the sub-movable arm 7d.

[0201] The intermediate movable arm 7e extends from the movable arm 7c. The intermediate movable arm 7e extends along the inner surface of the second connecting plate 6b. The intermediate movable arm 7e extends in the length direction of the spiral body 7a. For example, the intermediate movable arm 7e extends parallel to the length direction of the spiral body 7a. The intermediate movable arm 7e is pressed against the inner surface of the second connecting plate 6b by the restoring force of the torsion coil spring 7.

[0202] The auxiliary movable arm 7d extends from the intermediate movable arm 7e. The auxiliary movable arm 7d passes through the first auxiliary connecting hole 5f and the second auxiliary connecting hole 6f. The auxiliary movable arm 7d extends from the second auxiliary connecting hole 6f to the inner side of the second connecting plate 6b, and then extends downward and toward the inner surface of the second connecting plate 6b, and then connects to the intermediate movable arm 7e. The auxiliary movable arm 7d is pressed against the inner surface of the second connecting plate 6b by the restoring force of the torsion coil spring 7.

[0203] In addition, the auxiliary movable arm 7d extends from the first auxiliary connecting hole 5f to the inner side of the first connecting plate 5b, and further extends toward the spiral body 7a. The auxiliary movable arm 7d is pressed against the outer periphery of the spiral body 7a by the restoring force of the torsion coil spring 7. For example, the auxiliary movable arm 7d extends between the spiral body 7a and the intermediate movable arm 7e in parallel with the movable arm 7c.

[0204] The fixing portion of the first connecting plate 5b fixing the fixed arm 7b and the intermediate movable arm 7e are arranged in the thickness direction of the second connecting plate 6b. The fixing portion of the first connecting plate 5b fixing the fixed arm 7b and the intermediate movable arm 7e sandwich the second connecting plate 6b.

[0205] Here, the intermediate movable arm 7e can rotate by the torsion of the torsion coil spring 7 and move in the up-down direction outside the first connecting plate 5b. When the intermediate movable arm 7e moves upward outside the first connecting plate 5b, the spiral body 7a is wound tightly, and the restoring force of the torsion coil spring 7 increases. When the intermediate movable arm 7e moves downward outside the first connecting plate 5b, the spiral body 7a is loosened, and the restoring force of the torsion coil spring 7 decreases.

[0206] In addition, the auxiliary movable arm 7d can rotate by the torsion of the torsion coil spring 7 and move in the up-down direction outside the first connecting plate 5b. When the auxiliary movable arm 7d moves upward outside the first connecting plate 5b, the spiral body 7a is wound tightly, and the restoring force of the torsion coil spring 7 increases. When the auxiliary movable arm 7d moves downward outside the first connecting plate 5b, the spiral body 7a is loosened, and the restoring force of the torsion coil spring 7 decreases.

[0207] That is, when the torsion coil spring 7 is arranged as described above, the side of the auxiliary movable arm 7d and the intermediate movable arm 7e that winds up the spiral body 7a is upward, and the side of the auxiliary movable arm 7d and the intermediate movable arm 7e that loosens the spiral body 7a is downward.

[0208] In addition, in the state where the first panel 5 and the second panel 6 are separated, the auxiliary movable arm 7d extends to the outside of the first connecting plate 5b through the first auxiliary connecting hole 5f, and then extends downward and toward the outer surface of the first connecting plate 5b. The gap between the auxiliary movable arm 7d and the outer surface of the first connecting plate 5b and the gap between the intermediate movable arm 7e and the outer surface of the first connecting plate 5b are smaller than the thickness of the second connecting plate 6b. For example, the auxiliary movable arm 7d and the intermediate movable arm 7e are pressed against the outer surface of the first connecting plate 5b.

[0209] In addition, from the state where the first panel 5 and the second panel 6 are separated, the movable arm 7c can be inserted through the second connection hole 6c, and the sub-movable arm 7d can be inserted through the second sub-connection hole 6f.

[0210] Furthermore, the intermediate movable arm 7e can pass through the second intermediate connecting hole 6g, and the outer surface of the first connecting plate 5b and the outer surface of the second connecting plate 6b can overlap.

[0211] Moreover, when the first panel 5 moves downward relative to the second panel 6, the movable arm 7c, the auxiliary movable arm 7d and the intermediate movable arm 7e can climb onto the inner surface of the second connecting plate 6b and be pressed against the inner surface of the second connecting plate 6b by the restoring force of the torsion coil spring 7.

[0212] The panel connection structure in the third embodiment is configured as described above, and connects the first panel 5 and the second panel 6 .

[0213] In the panel connection structure of embodiment 3, the first connection plate 5b is provided with a first auxiliary connection hole 5f and a first intermediate connection hole 5g communicating with the first connection hole 5c and the first auxiliary connection hole 5f, the second connection plate 6b is provided with a second auxiliary connection hole 6f and a second intermediate connection hole 6g communicating with the second connection hole 6c and the second auxiliary connection hole 6f, the first auxiliary connection hole 5f is opposite to the second auxiliary connection hole 6f, and the first intermediate connection hole 5g is opposite to the second intermediate connection hole 6g, the torsion coil spring 7 has an auxiliary movable arm 7d and an intermediate movable arm 7e formed as a whole with the movable arm 7c, the intermediate movable arm 7e extends from the movable arm 7c along the inner surface of the second connection plate 6b, and is connected to the torsion coil spring 7 by The auxiliary movable arm 7d is pressed against the inner surface of the second connecting plate 6b by the restoring force of the intermediate movable arm 7e, and passes through the first auxiliary connecting hole 5f and the second auxiliary connecting hole 6f, and is pressed against the inner surface of the second connecting plate 6b and the outer periphery of the spiral body 7a by the restoring force of the torsion coil spring 7, wherein, when the first panel 5 and the second panel 6 are separated, the auxiliary movable arm 7d passes through the first auxiliary connecting hole 5f and extends to the outside of the first connecting plate 5b, and then extends toward the side of the loosened spiral body 7a and the outer surface of the first connecting plate 5b, and the gap between the auxiliary movable arm 7d and the first connecting plate 5b and the gap between the intermediate movable arm 7e and the first connecting plate 5b are smaller than the thickness of the second connecting plate 6b.

[0214] As a result, the positions of the movable arm 7c, the auxiliary movable arm 7d, and the intermediate movable arm 7e are stabilized, and the movable arm 7c, the auxiliary movable arm 7d, and the intermediate movable arm 7e can be firmly pressed against the inner surface of the second connecting plate 6b. In particular, since the movable arm 7c is suppressed from twisting, the movable arm 7c, the auxiliary movable arm 7d, and the intermediate movable arm 7e can be firmly pressed against the inner surface of the second connecting plate 6b.

[0215] In the panel connection structure in embodiment 3, from the state where the first panel 5 and the second panel 6 are separated, the movable arm 7c can pass through the second connection hole 6d, and the sub-movable arm 7d can pass through the second sub-connection hole 6f, and the intermediate movable arm 7e can pass through the second intermediate connection hole 6g, and the outer surface of the first connection plate 5b and the outer surface of the second connection plate 6b can overlap, and when the first panel 5 moves relative to the second panel 6 toward the side of the loosening spiral body 7a of the movable arm 7c, the movable arm 7c, the sub-movable arm 7d and the intermediate movable arm 7e can climb onto the inner surface of the second connection plate 6b and be pressed against the inner surface of the second connection plate 6b by the restoring force of the torsion coil spring 7.

[0216] Thereby, the movable arm 7c, the sub-movable arm 7d, and the intermediate movable arm 7e can be easily pressed against the inner surface of the second connecting plate 6b.

[0217] In addition, the first panel 5 and the second panel 6 can be connected from a desired side. For example, the first panel 5 and the second panel 6 can be connected from the car room 1.

[0218] In the panel connection structure of embodiment 3, the fixed arm 7b is fixed to the first connection plate 5b, and the fixing portion of the first connection plate 5b that fixes the fixed arm 7b and the intermediate movable arm 7e sandwich the second connection plate 6b in the thickness direction of the second connection plate 6b.

[0219] Thereby, the first panel 5 and the second panel 6 can be connected more firmly.

[0220] Furthermore, since the deflection generated in the first connection plate 5b and the second connection plate 6b is suppressed by the restoring force of the torsion coil spring 7, it is possible to make it difficult for a gap to be generated between the first connection plate 5b and the second connection plate 6b.

[0221] Next, use Fig.21 and Fig. 22 A method for connecting panels according to the third embodiment will be described.

[0222] Fig.21 This is a flowchart showing a panel connection method in the third embodiment. Fig. 22 This is a diagram showing a method of connecting panels in the third embodiment. Fig. 22 is with Fig.18 The corresponding figure. Fig. 22 (a) means Fig.21 FIG. 5 is a diagram of step S31 in FIG. Fig. 22 (b) means Fig.21 FIG. 5 is a diagram of step S32 in FIG. Fig. 22 (c) means Fig.21 FIG. 1 is a diagram of step S33 in FIG. Fig. 22 In (c), the movement of the movable arm 7c is indicated by a two-dot chain line. Fig. 22 (d) means Fig.21 FIG. 5 is a diagram of step S34 in FIG.

[0223] The panel connection method in the third embodiment includes: Fig.21 The steps shown in S31 to S34.

[0224] In step S31 (movable arm insertion step), the movable arm 7c is inserted through the second connection hole 6c and the sub-movable arm 7d is inserted through the second sub-connection hole 6f from the state where the first panel 5 and the second panel 6 are separated.

[0225] At this time, the first panel 5 is located above the second panel 6. In addition, the second panel 6 is previously attached to the attachment position of the car floor.

[0226] In step S32 (coupling plate overlapping step), the intermediate movable arm 7e is passed through the second intermediate coupling hole 6g, and the outer surface of the first coupling plate 5b is overlapped with the outer surface of the second coupling plate 6b.

[0227] At this time, the first panel 5 is located above the second panel 6 .

[0228] In step S33 (movable arm pressing step), the first panel 5 is moved downward, so that the movable arm 7c, the auxiliary movable arm 7d and the intermediate movable arm 7e are mounted on the inner surface of the second connecting plate 6b, and are pressed against the inner surface of the second connecting plate 6b by the restoring force of the torsion coil spring 7.

[0229] When the first panel 5 is moved downward in a state where the outer surfaces of the first connection plate 5b and the second connection plate 6b overlap, the movable arm 7c, the auxiliary movable arm 7d, and the intermediate movable arm 7e climb onto the inner surface of the second connection plate 6b.

[0230] Thus, the movable arm 7 c , the sub-movable arm 7 d , and the intermediate movable arm 7 e are pressed against the inner surface of the second connecting plate 6 b by the restoring force of the torsion coil spring 7 .

[0231] At this time, the first panel 5 is located above the second panel 6 .

[0232] In step S34 (connecting plate positioning step), the first panel 5 is moved downward to align the position of the first connecting plate 5 b with the position of the second connecting plate 6 b .

[0233] The first panel 5 is moved downward while the outer surface of the first connecting plate 5b overlaps with the outer surface of the second connecting plate 6b, thereby aligning the height direction of the first connecting plate 5b with the second connecting plate 6b. When the first panel 5 is moved, the movable arm 7c, the auxiliary movable arm 7d, and the intermediate movable arm 7e move along the inner surface of the second connecting plate 6b.

[0234] If the first connecting plate 5b and the second connecting plate 6b are misaligned in width direction, the first panel 5 is moved in the thickness direction to align the first connecting plate 5b and the second connecting plate 6b in width direction.

[0235] Thereby, the movable arm 7c, the auxiliary movable arm 7d, and the intermediate movable arm 7e are pressed against the inner surface of the second connecting plate 6b, and the first panel 5 is attached to the attachment position of the car floor.

[0236] The panel connecting method in the third embodiment is performed as described above, and the first panel 5 and the second panel 6 are connected.

[0237] The panel connecting method in embodiment 3 includes: step S31 of passing the movable arm 7c through the second connecting hole 6c from the state where the first panel 5 and the second panel 6 are separated; and step S33 of pressing the movable arm 7c against the inner surface of the second connecting plate 6b by the restoring force of the torsion coil spring 7.

[0238] Thus, even if the thickness of at least one of the first connection plate 5 b and the second connection plate 6 b that overlap when connecting the first panel 5 and the second panel 6 varies, the first panel 5 and the second panel 6 can be connected.

[0239] The panel connecting method in embodiment 3 includes: step S31, from the state where the first panel 5 and the second panel 6 are separated, the movable arm 7c is passed through the second connecting hole 6c, and the auxiliary movable arm 7d is passed through the second auxiliary connecting hole 6f; step S32, the intermediate movable arm 7e is passed through the second intermediate connecting hole 6g, and the outer surface of the first connecting plate 5b is overlapped with the outer surface of the second connecting plate 6b; and step S33, by moving the first panel 5 downward, the movable arm 7c, the auxiliary movable arm 7d and the intermediate movable arm 7e are climbed onto the inner surface of the second connecting plate 6b, and the restoring force of the torsion coil spring 7 is used to press on the inner surface of the second connecting plate 6b.

[0240] Thereby, the movable arm 7c, the sub-movable arm 7d, and the intermediate movable arm 7e can be easily pressed against the inner surface of the second connecting plate 6b.

[0241] In addition, the first panel 5 and the second panel 6 can be connected from a desired side. For example, the first panel 5 and the second panel 6 can be connected from the car room 1.

[0242] In addition, the positions of the movable arm 7c, the auxiliary movable arm 7d, and the intermediate movable arm 7e are stable, and the movable arm 7c, the auxiliary movable arm 7d, and the intermediate movable arm 7e can be firmly pressed against the inner surface of the second connecting plate 6b. In particular, since the movable arm 7c is suppressed from twisting, the movable arm 7c, the auxiliary movable arm 7d, and the intermediate movable arm 7e can be firmly pressed against the inner surface of the second connecting plate 6b.

[0243] In addition, in embodiment 3, the first connecting hole 5c, the first auxiliary connecting hole 5f, the first intermediate connecting hole 5g, the second connecting hole 6c, the second auxiliary connecting hole 6f, the second intermediate connecting hole 6g and the torsion coil spring 7 can also be reversed in the width direction of the first connecting plate 5b and the second connecting plate 6b.

[0244] In the third embodiment, the first connection hole 5c, the first auxiliary connection hole 5f, the first intermediate connection hole 5g, the second connection hole 6c, the second auxiliary connection hole 6f, the second intermediate connection hole 6g, and the torsion coil spring 7 may be reversed in the vertical direction.

[0245] In addition, in embodiment 3, the first connecting hole 5c, the first sub-connecting hole 5f, the first intermediate connecting hole 5g, the second connecting hole 6c, the second sub-connecting hole 6f, the second intermediate connecting hole 6g and the torsion coil spring 7 can be rotated along the first connecting plate 5b and the second connecting plate 6b so that the length direction of the coil 7a is toward the up and down direction.

[0246] In the third embodiment, the first panel 5 and the second panel 6 may be integrally formed and reversed in the width direction of the first panel 5 and the second panel 6 .

[0247] In addition, in embodiment 3, by utilizing the first connecting hole 5c, the first sub-connecting hole 5f, the first intermediate connecting hole 5g, the second connecting hole 6c, the second sub-connecting hole 6f, the second intermediate connecting hole 6g and the torsion coil spring 7 to connect multiple parts of the first connecting plate 5b and the second connecting plate 6b, the first connecting plate 5b and the second connecting plate 6b can be prevented from being misaligned, and the first panel 5 and the second panel 6 can be connected more firmly.

[0248] Furthermore, the connection structure and the connection method of the third embodiment can be used for two panels 4 adjacent to each other at the corner of the car wall 2 .

[0249] Next, use Figure 23 to Figure 28 The panel connection structure according to the fourth embodiment will be described.

Fig.28 It is a figure which shows the attachment state of the stopper plate 8 in Embodiment 4. Fig.28 yes Fig.26 P-direction view.

[0251] The panel connection structure in the fourth embodiment is different from the panel connection structure in the third embodiment as follows.

[0252] The first connecting plate 5b is provided with a first connecting hole 5d and a first sub-connecting hole 5h replacing the first connecting hole 5c and the first sub-connecting hole 5f of the connecting structure of the panel in Embodiment 3. The second connecting plate 6b is provided with a second connecting hole 6d and a second sub-connecting hole 6h replacing the second connecting hole 6c and the second sub-connecting hole 6f of the connecting structure of the panel in Embodiment 3.

[0253] The first auxiliary connecting hole 5h and the second auxiliary connecting hole 6h are located at one end side of the spiral body 7a in the length direction of the spiral body 7a. The first auxiliary connecting hole 5h and the second auxiliary connecting hole 6h are opposite to each other. For example, the first auxiliary connecting hole 5h and the second auxiliary connecting hole 6h have the same shape. For example, the first auxiliary connecting hole 5h and the second auxiliary connecting hole 6h are directly opposite to each other.

[0254] The first auxiliary connecting hole 5h and the second auxiliary connecting hole 6h are long holes, and are formed as follows.

[0255] The length direction of the long hole is oriented in a direction of twisting relative to the length direction of the spiral body 7a. The length direction of the spiral body 7a is oriented in the horizontal direction, whereas the length direction of the long hole is oriented in the up-down direction. The restoring force of the torsion coil spring 7 when the auxiliary movable arm 7d is located at one end side of the length direction of the long hole is greater than the restoring force of the torsion coil spring 7 when the auxiliary movable arm 7d is located at the other end side of the length direction of the long hole. The width of one end side of the length direction of the long hole is greater than the width of the other end side of the length direction of the long hole. One end side of the length direction of the long hole becomes the upper side of the long hole. The other end side of the length direction of the long hole becomes the lower side of the long hole.

[0256] Among them, when the first panel 5 and the second panel 6 are separated, when the movable arm 7c, the auxiliary movable arm 7d and the intermediate movable arm 7e rotate upward, the movable arm 7c passes through the first connecting hole 5d, and the auxiliary movable arm 7d passes through the first auxiliary connecting hole 5h, and the intermediate movable arm 7e passes through the first intermediate connecting hole 5g, and the movable arm 7c, the auxiliary movable arm 7d and the intermediate movable arm 7e can be stored in a position closer to the inside than the outer surface of the first connecting plate 5b.

[0257] Moreover, the first connecting hole 5d is opposite to the second connecting hole 6d, and the first sub-connecting hole 5h is opposite to the second sub-connecting hole 6h, and the first intermediate connecting hole 5g is opposite to the second intermediate connecting hole 6g, and when the movable arm 7c, the sub-movable arm 7d and the intermediate movable arm 7e are released, through the restoring force of the torsion coil spring 7, the movable arm 7c passes through the first connecting hole 5d and the second connecting hole 6d, and the sub-movable arm 7d passes through the first sub-connecting hole 5h and the second sub-connecting hole 6h, and the intermediate movable arm 7e passes through the first intermediate connecting hole 5g and the second intermediate connecting hole 6g, and at least one of the movable arm 7c, the sub-movable arm 7d and the intermediate movable arm 7e can be pressed against the inner surface of the second connecting plate 6b.

[0258] When the outer surface of the first connecting plate 5b overlaps with the outer surface of the second connecting plate 6b, the movable arm 7c, the auxiliary movable arm 7d and the intermediate movable arm 7e can move along the inner surface of the second connecting plate 6b by the restoring force of the torsion coil spring 7.

[0259] In addition, the movable arm 7c, the auxiliary movable arm 7d, and the intermediate movable arm 7e are held by the stopper plate 8 at a position inside the outer surface of the first connecting plate 5b as described below, and can be released.

[0260] When the movable arm 7c, the auxiliary movable arm 7d and the intermediate movable arm 7e are stored in a position inner than the outer surface of the first connecting plate 5b, one end side of the stop plate 8 can pass through the first auxiliary connecting hole 5h, and abut against a portion of the inner surface of the first connecting plate 5b that is closer to the first surface plate 5a than the first auxiliary connecting hole 5h and a portion of the outer surface of the first connecting plate 5b that is closer to the first surface plate 5a than the first auxiliary connecting hole 5h, thereby crossing the first auxiliary connecting hole 5h.

[0261] Furthermore, the other end side of the stopper plate 8 can be fixed to the outside of the first panel 5. For example, the other end side of the stopper plate 8 is fixed to the outer surface of the first connecting plate 5b by the adhesive tape 9. For example, the other end side of the stopper plate 8 protrudes to the outside of the first surface plate 5a side of the first panel 5.

[0262] The auxiliary movable arm 7d is pressed against the stopper plate 8 by the restoring force of the torsion coil spring 7, so that the movable arm 7c, the auxiliary movable arm 7d, and the intermediate movable arm 7e can be held at positions inside the outer surface of the first connecting plate 5b.

[0263] Furthermore, by separating the other end of the stopper plate 8 from the first panel 5 and taking one end of the stopper plate 8 out of the first auxiliary connecting hole 5h to the outside of the first connecting plate 5b, the stopper plate 8 is disengaged from the first auxiliary connecting hole 5h, and the movable arm 7c, the auxiliary movable arm 7d, and the intermediate movable arm 7e can be released. Furthermore, the stopper plate 8 can be taken into the car chamber 1 from the gap between the first connecting plate 5b and the second connecting plate 6b.

[0264] The panel connection structure in the fourth embodiment is configured as described above, and connects the first panel 5 and the second panel 6 .

[0265] In the panel connection structure of embodiment 4, when the movable arm 7c, the sub-movable arm 7d and the intermediate movable arm 7e are rotated toward one side of the winding spiral 7a when the first panel 5 is separated from the second panel 6, the movable arm 7c passes through the first connecting hole 5d, the sub-movable arm 7d passes through the first sub-connecting hole 5h, and the intermediate movable arm 7e passes through the first intermediate connecting hole 5g, and the movable arm 7c, the sub-movable arm 7d and the intermediate movable arm 7e can be stored in a position closer to the inside than the outer surface of the first connecting plate 5b.

[0266] This can prevent the movable arm 7c, the auxiliary movable arm 7d, and the intermediate movable arm 7e from hitting surrounding objects and being damaged when the first panel 5 is moved. In other words, the space required for moving the first panel 5 can be reduced.

[0267] In the panel connection structure of embodiment 4, when the first panel 5 and the second panel 6 are separated, the movable arm 7c, the auxiliary movable arm 7d and the intermediate movable arm 7e are stored at a position closer to the inside than the outer surface of the first connecting plate 5b, and the first connecting hole 5d is opposite to the second connecting hole 6d, and the first auxiliary connecting hole 5h is opposite to the second auxiliary connecting hole 6h, and the first intermediate connecting hole 5g is opposite to the second intermediate connecting hole 6g, and when the movable arm 7c, the auxiliary movable arm 7d and the intermediate movable arm 7e are released, the movable arm 7c passes through the first connecting hole by the restoring force of the torsion coil spring 7. 5d and the second connecting hole 6d, and the auxiliary movable arm 7d passes through the first auxiliary connecting hole 5h and the second auxiliary connecting hole 6h, and the intermediate movable arm 7e passes through the first intermediate connecting hole 5g and the second intermediate connecting hole 6g, at least one of the movable arm 7c, the auxiliary movable arm 7d and the intermediate movable arm 7e can be pressed against the inner surface of the second connecting plate 6b, and when the outer surface of the first connecting plate 5b coincides with the outer surface of the second connecting plate 6b, the movable arm 7c, the auxiliary movable arm 7d and the intermediate movable arm 7e can be pressed against the inner surface of the second connecting plate 6b by the restoring force of the torsion coil spring 7.

[0268] Thereby, the movable arm 7c, the sub-movable arm 7d, and the intermediate movable arm 7e can be easily pressed against the inner surface of the second connecting plate 6b.

[0269] In addition, the first panel 5 and the second panel 6 can be connected from a desired side. For example, the first panel 5 and the second panel 6 can be connected from the car room 1.

[0270] In the connection structure of the panel of embodiment 4, the first connection hole 5d, the first sub-connection hole 5h, the second connection hole 6d and the second sub-connection hole 6h are long holes, and the length direction of the long hole is toward the direction of twisting relative to the length direction of the spiral body 7a. When the movable arm 7c and the sub-movable arm 7d are located at one end side of the long hole, the restoring force of the torsion coil spring 7 is greater than the restoring force of the torsion coil spring 7 when the movable arm 7c and the sub-movable arm 7d are located at the other end side of the long hole, and the width of one end side of the long hole in the length direction is greater than the width of the other end side in the length direction of the long hole.

[0271] Thereby, the movable arm 7c and the sub-movable arm 7d can be easily accommodated inwardly of the outer surface of the first connecting plate 5b.

[0272] In addition, when the first connection hole 5d and the second connection hole 6d are made to face each other, the movable arm 7c can be easily inserted through the first connection hole 5d and the second connection hole 6d even if the first connection hole 5d and the second connection hole 6d are offset in the width direction of the first connection hole 5d and the second connection hole 6d. Similarly, when the first auxiliary connection hole 5h and the second auxiliary connection hole 6h are made to face each other, the auxiliary movable arm 7d can be easily inserted through the first auxiliary connection hole 5h and the second auxiliary connection hole 6h even if the first auxiliary connection hole 5h and the second auxiliary connection hole 6h are offset in the width direction of the first auxiliary connection hole 5h and the second auxiliary connection hole 6h.

[0273] Furthermore, the width of the long hole increases toward one end of the long hole and decreases toward the other end of the long hole, whereby the movable arm 7c and the sub-movable arm 7d can smoothly move in the longitudinal direction of the long hole.

[0274] In the panel connection structure of the fourth embodiment, the first panel 5 has a first surface plate 5a, and the first connection plate 5b extends from the end of the first surface plate 5a in a direction perpendicular to the first surface plate 5a. When the movable arm 7c, the auxiliary movable arm 7d, and the intermediate movable arm 7e are stored in a position closer to the inside than the outer surface of the first connection plate 5b, one end side of the stopper plate 8 can pass through the first auxiliary connection hole 5h and connect with the inner surface of the first connection plate 5b closer to the first surface plate than the first auxiliary connection hole 5h. The portion on the opposite side of 5a and the portion of the outer surface of the first connecting plate 5b that is closer to the first surface plate 5a than the first secondary connecting hole 5h abut against each other, thereby spanning the first secondary connecting hole 5h, and the other end side of the stop plate 8 can be fixed to the outside of the first panel 5, and the secondary movable arm 7d is pressed against the stop plate 8 by the restoring force of the torsion coil spring 7, thereby the movable arm 7c, the secondary movable arm 7d and the intermediate movable arm 7e can be maintained at a position closer to the inside than the outer surface of the first connecting plate 5b.

[0275] Thereby, the movable arm 7c, the sub-movable arm 7d, and the intermediate movable arm 7e can be easily held at the inner side of the outer surface of the first connecting plate 5b.

[0276] Next, use Fig.29 and Fig.30 A method for connecting panels according to the fourth embodiment will be described.

[0277] Fig.29 This is a flowchart showing a panel connection method in a fourth embodiment. Fig.30 This is a diagram showing a method of connecting panels in a fourth embodiment. Fig.30 is with Fig.24 and Fig. 27 The corresponding figure. Fig.30 In FIG. 1 , the helical body 7a is indicated by a double-dashed line. Fig.30 (a) means Fig.29 FIG. 4 is a diagram of step S41 in FIG. Fig.30 (b) means Fig.29 FIG. 4 is a diagram of step S42 in FIG. Fig.30 (c) means Fig.29 FIG. 4 is a diagram of step S43 in FIG. Fig.30 (d) means Fig.29 FIG. 4 is a diagram of step S44 in FIG. Fig.30 (c) and Fig.30 In (d), the movement of the auxiliary movable arm 7d and the intermediate movable arm 7e are indicated by two-dot chain lines.

[0278] The panel connection method in the fourth embodiment includes: Fig.29 The steps shown in S41 to S44.

[0279] In step S41 (movable arm storing step), the movable arm 7c, the sub-movable arm 7d, and the intermediate movable arm 7e are stored inside the outer surface of the first connecting plate 5b in a state where the first panel 5 and the second panel 6 are separated.

[0280] By rotating the movable arm 7c, the auxiliary movable arm 7d and the intermediate movable arm 7e upward, the movable arm 7c is passed through the first connecting hole 5d, the auxiliary movable arm 7d is passed through the first auxiliary connecting hole 5h, and the intermediate movable arm 7e is passed through the first intermediate connecting hole 5g, so that the movable arm 7c, the auxiliary movable arm 7d and the intermediate movable arm 7e are stored at a position closer to the inside than the outer surface of the first connecting plate 5b.

[0281] As described below, the movable arm 7c, the auxiliary movable arm 7d, and the intermediate movable arm 7e are held by the stopper plate 8 at a position inside the outer surface of the first connection plate 5b.

[0282] When the movable arm 7c, the auxiliary movable arm 7d and the intermediate movable arm 7e are stored in a position inner than the outer surface of the first connecting plate 5b, one end side of the stop plate 8 passes through the first auxiliary connecting hole 5h, and abuts against a portion of the inner surface of the first connecting plate 5b that is closer to the first surface plate 5a than the first auxiliary connecting hole 5h and a portion of the outer surface of the first connecting plate 5b that is closer to the first surface plate 5a than the first auxiliary connecting hole 5h, thereby crossing the first auxiliary connecting hole 5h.

[0283] Furthermore, the other end side of the stopper plate 8 is fixed to the outside of the first panel 5. For example, the other end side of the stopper plate 8 is fixed to the outer surface of the first connecting plate 5b using an adhesive tape 9. For example, the other end side of the stopper plate 8 protrudes to the outside of the first surface plate 5a side of the first panel 5.

[0284] Furthermore, the auxiliary movable arm 7d is pressed against the stopper plate 8 by the restoring force of the torsion coil spring 7, thereby holding the movable arm 7c, the auxiliary movable arm 7d, and the intermediate movable arm 7e at positions inside the outer surface of the first connecting plate 5b.

[0285] In step S42 (connection hole facing step), the first connection hole 5d and the second connection hole 6d are faced to each other, the first auxiliary connection hole 5h and the second auxiliary connection hole 6h are faced to each other, and the first intermediate connection hole 5g and the second intermediate connection hole 6g are faced to each other.

[0286] In addition, the second panel 6 is installed in advance at the installation position of the car floor. In addition, a gap is left between the outer surface of the first connecting plate 5b and the outer surface of the second connecting plate 6b so that the stopper plate 8 can be taken into the car room 1 in step S43.

[0287] In process S43 (movable arm pressing process), the movable arm 7c, the sub-movable arm 7d and the intermediate movable arm 7e are released, and the restoring force of the torsion coil spring 7 is used to make the movable arm 7c pass through the first connecting hole 5d and the second connecting hole 6d, and the sub-movable arm 7d pass through the first sub-connecting hole 5h and the second sub-connecting hole 6h, and the intermediate movable arm 7e pass through the first intermediate connecting hole 5g and the second intermediate connecting hole 6g, and at least one of the movable arm 7c, the sub-movable arm 7d and the intermediate movable arm 7e is pressed against the inner surface of the second connecting plate 6b.

[0288] In addition, the movable arm 7c, the auxiliary movable arm 7d, and the intermediate movable arm 7e are released as described below.

[0289] The other end of the stopper plate 8 is separated from the first panel 5, and one end of the stopper plate 8 is taken out from the first auxiliary connecting hole 5h to the outside of the first connecting plate 5b, thereby disengaging the stopper plate 8 from the first auxiliary connecting hole 5h, releasing the movable arm 7c, the auxiliary movable arm 7d, and the intermediate movable arm 7e. Then, the stopper plate 8 is taken into the car chamber 1 from the gap between the first connecting plate 5b and the second connecting plate 6b.

[0290] In process S44 (connecting plate overlap process), by making the outer surface of the first connecting plate 5b overlap with the outer surface of the second connecting plate 6b, the movable arm 7c, the auxiliary movable arm 7d and the intermediate movable arm 7e are pressed against the inner surface of the second connecting plate 6b by utilizing the restoring force of the torsion coil spring 7, and the position of the first connecting plate 5b is aligned with the position of the second connecting plate 6b.

[0291] When the outer surface of the first connecting plate 5b is overlapped with the outer surface of the second connecting plate 6b, at least one of the movable arm 7c, the auxiliary movable arm 7d and the intermediate movable arm 7e moves along the inner surface of the second connecting plate 6b by the restoring force of the torsion coil spring 7.

[0292] If the first connecting plate 5b and the second connecting plate 6b are misaligned in width direction, the first panel 5 is moved in the thickness direction to align the first connecting plate 5b and the second connecting plate 6b in width direction.

[0293] Thereby, the movable arm 7c, the auxiliary movable arm 7d, and the intermediate movable arm 7e are pressed against the inner surface of the second connecting plate 6b, and the first panel 5 is attached to the attachment position of the car floor.

[0294] The panel connecting method in the fourth embodiment is performed as described above, and the first panel 5 and the second panel 6 are connected.

[0295] The panel connecting method in embodiment 4 includes: step S43 of passing the movable arm 7c through the second connecting hole 6d from the state where the first panel 5 and the second panel 6 are separated; and step S43 of pressing the movable arm 7c against the inner surface of the second connecting plate 6b by the restoring force of the torsion coil spring 7.

[0296] Thus, even if the thickness of at least one of the first connection plate 5 b and the second connection plate 6 b that overlap when connecting the first panel 5 and the second panel 6 varies, the first panel 5 and the second panel 6 can be connected.

[0297] The panel connection method in the fourth embodiment includes: step S41, in a state where the first panel 5 and the second panel 6 are separated, the movable arm 7c, the auxiliary movable arm 7d and the intermediate movable arm 7e are stored at a position closer to the inside than the outer surface of the first connecting plate 5b; step S42, the first connecting hole 5d is opposite to the second connecting hole 6d, the first auxiliary connecting hole 5h is opposite to the second auxiliary connecting hole 6h, and the first intermediate connecting hole 5g is opposite to the second intermediate connecting hole 6g; step S43, the movable arm 7c, the auxiliary movable arm 7d and the intermediate movable arm 7e are released, and the restoring force of the torsion coil spring 7 is used to make the movable arm 7c pass through Passing through the first connecting hole 5d and the second connecting hole 6d, and passing the auxiliary movable arm 7d through the first auxiliary connecting hole 5h and the second auxiliary connecting hole 6h, and passing the intermediate movable arm 7e through the first intermediate connecting hole 5g and the second intermediate connecting hole 6g, at least one of the movable arm 7c, the auxiliary movable arm 7d and the intermediate movable arm 7e is pressed against the inner surface of the second connecting plate 6b; and step S44, by making the outer surface of the first connecting plate 5b overlap with the outer surface of the second connecting plate 6b, the movable arm 7c, the auxiliary movable arm 7d and the intermediate movable arm 7e are pressed against the inner surface of the second connecting plate 6b by the restoring force of the torsion coil spring 7.

[0298] Thereby, the movable arm 7c, the sub-movable arm 7d, and the intermediate movable arm 7e can be easily pressed against the inner surface of the second connecting plate 6b.

[0299] In addition, the first panel 5 can be connected to the second panel 6 from a desired side. For example, the first panel 5 and the second panel 6 can be connected from the car room 1.

[0300] In addition, when the first panel 5 is moved, the movable arm 7c, the auxiliary movable arm 7d, and the intermediate movable arm 7e can be prevented from hitting surrounding objects and being damaged. In other words, the space required for moving the first panel 5 can be reduced.

[0301] In addition, the positions of the movable arm 7c, the auxiliary movable arm 7d, and the intermediate movable arm 7e are stable, and the movable arm 7c, the auxiliary movable arm 7d, and the intermediate movable arm 7e can be firmly pressed against the inner surface of the second connecting plate 6b. In particular, since the movable arm 7c is suppressed from twisting, the movable arm 7c, the auxiliary movable arm 7d, and the intermediate movable arm 7e can be firmly pressed against the inner surface of the second connecting plate 6b.

[0302] In the fourth embodiment, the movable arm 7c, the auxiliary movable arm 7d, and the intermediate movable arm 7e are held by the stopper plate 8 at the inner side of the outer surface of the first connecting plate 5b and are releasable as described below.

[0303] When the movable arm 7c, the sub-movable arm 7d and the intermediate movable arm 7e are stored in a position closer to the inside than the outer surface of the first connecting plate 5b, one end side of the stop plate 8 can pass through the target connecting hole, which is the first connecting hole 5c, the first sub-connecting hole 5h or the first intermediate connecting hole 5g, and abut against a portion of the inner surface of the first connecting plate 5b that is closer to one side than the target connecting hole and a portion of the outer surface of the first connecting plate 5b that is closer to the other side than the target connecting hole, thereby crossing the target connecting hole.

[0304] Furthermore, the other end side of the stopper plate 8 can be fixed to the outside of the first panel 5. For example, the other end side of the stopper plate 8 is fixed to the outer surface of the first connecting plate 5b by the adhesive tape 9. For example, the other end side of the stopper plate 8 protrudes to the outside of the first surface plate 5a side of the first panel 5.

[0305] Moreover, the object movable arm 7c, the auxiliary movable arm 7d or the intermediate movable arm 7e opposite to the object connecting hole is pressed against the stop plate 8 by the restoring force of the torsion coil spring 7, so that the movable arm 7c, the auxiliary movable arm 7d and the intermediate movable arm 7e can be maintained at a position closer to the inside than the outer surface of the first connecting plate 5b.

[0306] Furthermore, by separating the other end of the stopper plate 8 from the first panel 5 and taking one end of the stopper plate 8 out of the target connection hole to the outside of the first connection plate 5b, the stopper plate 8 is detached from the target connection hole, and the movable arm 7c, the auxiliary movable arm 7d, and the intermediate movable arm 7e can be released. Furthermore, the stopper plate 8 can be taken into the car chamber 1 from the gap between the first connection plate 5b and the second connection plate 6b.

[0307] Furthermore, in the fourth embodiment, the first panel 5 may be mounted in advance at the mounting position of the car floor in step S42 , and the second panel 6 may be moved in steps S42 to S44 .

[0308] In addition, in embodiment 4, the first connecting hole 5d, the first auxiliary connecting hole 5h, the first intermediate connecting hole 5g, the second connecting hole 6d, the second auxiliary connecting hole 6h, the second intermediate connecting hole 6g and the torsion coil spring 7 can also be reversed in the width direction of the first connecting plate 5b and the second connecting plate 6b.

[0309] In the fourth embodiment, the first connection hole 5d, the first auxiliary connection hole 5h, the first intermediate connection hole 5g, the second connection hole 6d, the second auxiliary connection hole 6h, the second intermediate connection hole 6g, and the torsion coil spring 7 may be reversed in the vertical direction.

[0310] In addition, in embodiment 4, the first connecting hole 5d, the first sub-connecting hole 5h, the first intermediate connecting hole 5g, the second connecting hole 6d, the second sub-connecting hole 6h, the second intermediate connecting hole 6g and the torsion coil spring 7 can be rotated along the first connecting plate 5b and the second connecting plate 6b so that the length direction of the coil 7a is toward the up and down direction.

[0311] In the fourth embodiment, the first panel 5 and the second panel 6 may be integrally formed and reversed in the width direction of the first panel 5 and the second panel 6 .

[0312] In addition, in embodiment 4, by utilizing the first connecting hole 5d, the first sub-connecting hole 5h, the first intermediate connecting hole 5g, the second connecting hole 6d, the second sub-connecting hole 6h, the second intermediate connecting hole 6g and the torsion coil spring 7 to connect multiple parts of the first connecting plate 5b and the second connecting plate 6b, the first connecting plate 5b and the second connecting plate 6b can be prevented from being misaligned, and the first panel 5 and the second panel 6 can be connected more firmly.

[0313] Furthermore, the connection structure and the connection method of the fourth embodiment can be used for two panels 4 adjacent to each other at the corner of the car wall 2 .

[0314] Next, use Figure 31 to Figure 33 A panel connection structure in a first modified example of the fourth embodiment will be described.

Fig.31 is with Fig.26 The corresponding figure. Fig.32 It is a figure which shows the attachment state of the stopper plate 10 in the 1st modification of Embodiment 4.

Fig.33 It is a figure which shows the attachment state of the stopper plate 10 in the 1st modification of Embodiment 4. Fig.33 yes Fig.31 SS view in the figure. Fig.33 is with Fig.28 The corresponding figure.

[0316] The panel connection structure in the first modified example of the fourth embodiment is different from the panel connection structure in the fourth embodiment as follows.

[0317] The movable arm 7c, the auxiliary movable arm 7d and the intermediate movable arm 7e are held at positions inside the outer surface of the first connecting plate 5b by the stopper plate 10 replacing the stopper plate 8 of the panel connecting structure in the fourth embodiment and are releasable.

[0318] When the movable arm 7c, the sub-movable arm 7d and the intermediate movable arm 7e are stored in a position inner than the outer surface of the first connecting plate 5b, one end side of the stop plate 10 can pass through the outer side of the first panel 5 on the opposite side of the first surface plate 5a, and abut against the portion of the inner surface of the first connecting plate 5b on the opposite side of the first sub-connecting hole 5h to the first surface plate 5a and the portion of the inner surface of the first connecting plate 5b on the first surface plate 5a side than the first sub-connecting hole 5h, thereby crossing the first sub-connecting hole 5h.

[0319] Moreover, one end side of the stop plate 10 can abut against a portion of the inner surface of the first connecting plate 5b that is closer to the first surface plate 5a than the first intermediate connecting hole 5g and a portion of the inner surface of the first connecting plate 5b that is closer to the first surface plate 5a than the first intermediate connecting hole 5g, thereby spanning the first intermediate connecting hole 5g.

[0320] Moreover, one end side of the stop plate 10 can abut against a portion of the inner surface of the first connecting plate 5b that is closer to the first surface plate 5a than the first connecting hole 5d and a portion of the inner surface of the first connecting plate 5b that is closer to the first surface plate 5a than the first connecting hole 5d, thereby crossing the first connecting hole 5d.

[0321] For example, the first panel 5 is provided with a stop plate mounting hole 5e on the side opposite to the first surface plate 5a than the first connecting hole 5d, the first sub-connecting hole 5h and the first intermediate connecting hole 5g. The stop plate mounting hole 5e connects the outer side and the inner side of the first panel 5 on the side opposite to the first surface plate 5a, and one end side of the stop plate 10 can be inserted and pulled out along the width direction of the first connecting plate 5b.

[0322] The other end of the stopper plate 10 can be opposed to the outer surface of the first connecting plate 5 b . For example, the other end of the stopper plate 10 protrudes outward on the first surface plate 5 a side of the first panel 5 .

[0323] The movable arm 7c, the auxiliary movable arm 7d and the intermediate movable arm 7e are pressed against the stopper plate 10 by the restoring force of the torsion coil spring 7, so that the movable arm 7c, the auxiliary movable arm 7d and the intermediate movable arm 7e can be held at a position inside the outer surface of the first connecting plate 5b.

[0324] Furthermore, by taking out one end side of the stopper plate 10 to the outside of the first panel 5 on the side opposite to the first surface plate 5a, the stopper plate 10 is disengaged from the first connection hole 5d, the first auxiliary connection hole 5h and the first intermediate connection hole 5g, and the movable arm 7c, the auxiliary movable arm 7d and the intermediate movable arm 7e can be released. Furthermore, the stopper plate 10 can be taken into the car chamber 1 from the gap between the first connection plate 5b and the second connection plate 6b.

[0325] The panel connection structure in the first modified example of the fourth embodiment is configured as described above, and connects the first panel 5 and the second panel 6 .

[0326] In the panel connection structure of the first variant of embodiment 4, the first panel 5 has a first surface plate 5a, and the first connecting plate 5b extends from the end of the first surface plate 5a in a direction perpendicular to the first surface plate 5a. When the movable arm 7c, the sub-movable arm 7d and the intermediate movable arm 7e are stored in a position closer to the inside than the outer surface of the first connecting plate 5b, one end side of the stop plate 10 can pass through the outer side of the first panel 5 on the opposite side of the first surface plate 5a, and abut against a portion of the inner surface of the first connecting plate 5b that is closer to the opposite side of the first surface plate 5a than the first sub-connecting hole 5h and a portion of the inner surface of the first connecting plate 5b that is closer to the first surface plate 5a than the first sub-connecting hole 5h, thereby crossing the first sub-connecting hole 5h, and one end side of the stop plate 10 can abut against a portion of the inner surface of the first connecting plate 5b that is closer to the first surface than the first intermediate connecting hole 5g. The portion on the opposite side of the plate 5a and the portion of the inner surface of the first connecting plate 5b that is closer to the first surface plate 5a side than the first intermediate connecting hole 5g abut against each other, thereby spanning the first intermediate connecting hole 5g, and one end side of the stop plate 10 can abut against the portion of the inner surface of the first connecting plate 5b that is closer to the opposite side of the first surface plate 5a than the first connecting hole 5d and the portion of the inner surface of the first connecting plate 5b that is closer to the first surface plate 5a side than the first connecting hole 5d, thereby spanning the first connecting hole 5d, and the other end side of the stop plate 10 can be opposite to the outer surface of the first connecting plate 5b, and the movable arm 7c, the auxiliary movable arm 7d and the intermediate movable arm 7e are pressed against the stop plate 10 by the restoring force of the torsion coil spring 7, thereby the movable arm 7c, the auxiliary movable arm 7d and the intermediate movable arm 7e can be maintained at a position closer to the inside than the outer surface of the first connecting plate 5b.

[0327] Thereby, the movable arm 7c, the sub-movable arm 7d, and the intermediate movable arm 7e can be easily held at the inner side of the outer surface of the first connecting plate 5b.

[0328] In the first modified example of the fourth embodiment, the movable arm 7c, the auxiliary movable arm 7d, and the intermediate movable arm 7e are held by the stopper plate 10 at positions inside the outer surface of the first connecting plate 5b and are releasable as described below.

[0329] When the movable arm 7c, the sub-movable arm 7d and the intermediate movable arm 7e are stored in a position inner than the outer surface of the first connecting plate 5b, one end side of the stop plate 10 can pass through the outer side of the first panel 5 on the opposite side of the first surface plate 5a, and abut against a portion of the inner surface of the first connecting plate 5b that is closer to one side of the target connecting hole, which is the first connecting hole 5d, the first sub-connecting hole 5h or the first intermediate connecting hole 5g, and a portion of the inner surface of the first connecting plate 5b that is closer to the other side of the target connecting hole, thereby crossing the target connecting hole.

[0330] The other end of the stopper plate 10 can be opposed to the outer surface of the first connecting plate 5 b . For example, the other end of the stopper plate 10 protrudes outward on the first surface plate 5 a side of the first panel 5 .

[0331] Moreover, the target movable arm 7c, the auxiliary movable arm 7d or the intermediate movable arm 7e opposite to the target connecting hole is pressed against the stop plate 10 by the restoring force of the torsion coil spring 7, so that the movable arm 7c, the auxiliary movable arm 7d and the intermediate movable arm 7e can be maintained at a position closer to the inside than the outer surface of the first connecting plate 5b.

[0332] Furthermore, by taking out one end side of the stopper plate 10 to the outside of the first panel 5 on the side opposite to the first surface plate 5a, the stopper plate 10 is disengaged from the target connection hole, and the movable arm 7c, the auxiliary movable arm 7d, and the intermediate movable arm 7e can be released. Furthermore, the stopper plate 10 can be taken into the car chamber 1 from the gap between the first connection plate 5b and the second connection plate 6b.
