Regarding railway vehicles.

Conventional commuter rail cars may be equipped with various mechanisms to change the usage status of seats in the cabin. The mechanism includes, for example, a mechanism that allows the seat to be turned forward or backward in the direction of travel, a mechanism that allows the cushion part to be folded, or a rotary conversion mechanism that allows for long seats facing the aisle and rails. There are mechanisms that can switch between a cross-seat state and a facing direction. There are also cushions that can be folded up and used as a place to store suitcases, etc.

For example, Patent Document 1 discloses a seat conversion mechanism that has a rotary conversion mechanism and can convert between a long seat state facing the aisle and a cross seat state facing the rail direction. That is, as shown in FIGS. 12 and 13, a leg frame 102 is provided so as to be movable with respect to the floor via casters 101, and a leg frame 102 is rotatably provided on the leg frame 102 via a rotation mechanism 103. a seat frame 104 with a base end rotatably attached to the side of the vehicle, and a first link 105 with a distal end rotatably attached to the leg frame 102; The long seat position of the leg frame 102 includes a second link 106 which is rotatably attached and whose tip end is rotatably attached to the leg frame 102, the leg frame 102, and a vehicle side surface 107; A seat conversion mechanism 100 is disclosed that includes a link mechanism 108 that provides guidance between cross seat positions.

In the railway vehicle 10 (10A, 10B, 10C, 10D, 10E) according to this embodiment, as shown in FIG. An upper fixing mechanism 3 is provided on the floor 21 of the passenger room 2 to fix the position of the seat (transportable object) 1, and the seat (transportable object) 1 is provided with an upper fixing mechanism 3 that can be connected to the upper fixing mechanism 3. A correspondingly arranged lower fixing mechanism 4 is provided. Note that specific examples of the upper fixing mechanism 3 and the lower fixing mechanism 4 will be explained in the first embodiment and the second embodiment shown in FIGS. 7 to 10.

In addition, a steel plate member 22K that can be magnetically attracted is laid on the floorboard 22 constituting the floor 21 of the guest room 2, and a steel plate member 22K that can be magnetically attracted is placed on the floor side of the seat (portable object) 1. A second magnet body 5 formed to be retractable from the lower end 11 and capable of being magnetically attracted to the steel plate member 22K when placed at a fixed position may be provided at a different position from the upper fixing mechanism 3. preferable. In this case, as shown in FIG. 6(A), when the upper fixing mechanism 3 and the lower fixing mechanism 4 are connected, the second magnet body 5 magnetically attracts the steel plate member 22K of the floor plate 22. The rattling and chattering sound of the seat (portable object) 1 can be suppressed. The second magnet body 5 functions as an auxiliary mechanism for the fixing mechanism (upper fixing mechanism 3 and lower fixing mechanism 4).

The second magnet body 5 may be made of an electromagnet or a permanent magnet as long as it can turn on/off or increase/decrease the magnetism exposed to the outside. For example, in the case of an electromagnet, the portable object 1 can be easily moved by cutting off the coil current. In addition, in the case of a permanent magnet, the portable object 1 can be easily moved by mounting the magnet piece inside the case so that it can move up and down, and by raising the magnet piece to reduce the magnetism exposed from the outside. I can do it.

Further, on the floor side of the seat (portable object) 1, casters 6 formed so as to be able to appear and retract from the lower end 11 of the seat (portable object) 1 are provided at a different position from the upper fixing mechanism 3. It is preferable. In this case, as shown in FIG. 6(B), even if the seat (portable object) 1 is heavy, the casters 6 can be made to protrude from the lower end 11 of the seat (portable object) 1, so that the seat (portable object) can be easily Transportable objects) 1 can be moved. Furthermore, since the casters 6 are formed so as to be retractable from the lower end 11 of the seat (portable object) 1, the seat (portable object) 1 is placed in a fixed position as shown in FIG. 6(A). In this case, the casters 6 can be stored in the lower end 11 of the seat (portable object) 1, and the load due to the weight of the seat (portable object) 1 does not need to be applied to the floorboard 22 via the casters 6. The casters 6 function as an auxiliary mechanism for transporting the seat (portable object) 1. Here, the seat (portable object) 1 is connected to the upper fixing mechanism 3, the second magnet body 5, and the casters 6, and is equipped with an operating lever 34 for operating each of these operations.

Next, a first embodiment of the upper fixing mechanism 3 and the lower fixing mechanism 4 will be described. That is, as shown in FIG. 7, the lower fixing mechanism 4 according to the first embodiment has position fixing holes 221 formed in the floorboard 22 of the passenger room 2 corresponding to a plurality of fixing positions of the seat (portable object) 1. The connecting pin 4P has a shaft portion 41 vertically movably inserted into the connecting pin 4P, and the upper end portion 42 of the shaft portion 41 has a surface that is flush with the floor plate 22 at the lowered position of the connecting pin 4P (see FIG. 7(A)). An upper flange portion 42H is formed that abuts in one shape. Further, the lower end portion 43 of the shaft portion 41 has a lower flange that contacts the floor plate 22 with the upper flange portion 42H protruding upward from the floor plate 22 when the connecting pin 4P is in the raised position (see FIG. 7(B)). A portion 43H is formed. Here, the shaft portion 41 of the connecting pin 4P is formed in a cylindrical shape that stands up in the vertical direction, and the upper collar portion 42H and the lower collar portion 43H are formed as annular collar portions having a larger outer diameter than the shaft portion 41. (See Figure 7(C)). Note that the floor surface 21 of the guest room 2 is provided with a floor padding 23 that supports the floorboard 22, and the floor padding 23 is formed to be able to accommodate the connecting pin 4P in the lowered position.

Further, as shown in FIGS. 8 and 9, the upper fixing mechanism 3 according to the first embodiment is inserted into the gap between the upper flange 42H of the connecting pin 4P and the floor plate 22 in the raised position, and the shaft 41 is inserted from both sides. It has a pair of sandwiching plates 3K (31K, 32K). The holding plate 3K (31K, 32K) has one end formed to be horizontally rotatable around the shaft pin 33K, and the long side on the closing side formed in a semicircular arc shape along the outer periphery of the shaft portion 41. It is a substantially rectangular plate-like body. The pair of clamping plates 3K (31K, 32K) are opened to a position where the upper flange 42H of the connecting pin 4P does not interfere in the released position (see FIG. 8(A)), and the closed position (see FIG. 8(B)). ), the connecting pin 4P is closed to a position where it comes into contact with the shaft portion 41 of the connecting pin 4P.

Then, as shown in FIG. 9, the connecting pin 4P of the lower fixing mechanism 4 inserted into the position fixing hole 221 formed in the floorboard 22 of the passenger room 2 corresponding to the fixing position of the seat (transportable object) 1 is raised. In this state, the shaft portion 41 of the connecting pin 4P is clamped by the clamping plate 3K of the upper fixing mechanism 3 to connect the upper fixing mechanism 3 and the lower fixing mechanism 4. Here, as shown in FIG. 9(B), when the shaft portion 41 of the connecting pin 4P is held between the holding plates 3K, the lower flange portion 43H of the connecting pin 4P comes into contact with the floor plate 22, and the connecting pin 4P rises. The upper flange 42H of the connecting pin 4P restricts the lifting of the holding plate 3K. As a result, in this railway vehicle 10, even if an inertia force acts on the seat (transportable object) 1 due to activation of an emergency brake or the like while the vehicle is running, the connection state between the upper fixing mechanism 3 and the lower fixing mechanism 4 can be maintained. It can be held stably.

Further, as shown in FIG. 9(A), the lower fixing mechanism 4 is a connecting pin 4P in which a shaft portion 41 is vertically movably inserted into a position fixing hole 221 formed in the floor plate 22. An upper flange portion 42H is formed on the upper end portion 42 of the connecting pin 4P so as to be in flush contact with the floor plate 22 at the lowered position of the connecting pin 4P. Further, the lower end portion 43 of the shaft portion 41 is formed with a lower flange portion 43H that comes into contact with the floor plate 22 in a state where the upper flange portion 42H protrudes upward from the floor plate 22 when the connecting pin 4P is in the raised position. As a result, the connecting pin 4P can be formed into a bobbin shape having an annular flange and can be formed compactly. Therefore, the lower fixing mechanism 4 can be installed in a required position on the floor surface 21 of the guest room 2 even more easily depending on various uses such as commuting, sightseeing, and events.

As shown in FIGS. 7 and 9, the connecting pin 4P is a magnet body 4PJ having opposing magnetic poles (N pole, S pole) at an upper end 42 and a lower end 43, and the connecting pin 4P is attached to the floor plate 22. It is preferable that a steel plate member 22K to which the pin 4P magnetically attracts is installed, and a position fixing hole 221 is formed in the steel plate member 22K. The magnet body 4PJ is made of, for example, a permanent magnet made of a hard magnetic material, and the upper end 42 of the connecting pin 4P is magnetized to the north pole, and the lower end 43 is magnetized to the south pole. Further, a cushion floor material 22S is laminated on the upper surface of the steel plate member 22K, and a ring-shaped frame 22R is fixed between the cushion floor material 22S and the upper flange 42H along the outer edge of the upper flange 42H. has been done. The thickness of the ring-shaped frame 22R is approximately the same as that of the cushion floor material 22S and the upper flange 42H. The steel plate member 22K may be made of a hard magnetic material with residual magnetism or a soft magnetic material with no residual magnetism.

Further, it is preferable that the seat (portable object) 1 is provided with a lifting magnet 43J that is movable up and down at a position where it abuts the upper end 42 of the shaft portion 41 of the connecting pin 4P. The pulling magnet 43J is made of the above-mentioned permanent magnet, for example, and has vertically opposing magnetic poles, and its lower end 431 has an opposite magnetic pole (S pole) to the magnetic pole (N pole) of the upper end 42 of the connecting pin 4P. ) is magnetized.

In this case, when the connecting pin 4P is used as the lower fixing mechanism 4, the pulling magnet 43J is lowered at the fixing position of the seat (transportable object) 1, and the upper flange 42H is attached to the steel plate member 22K of the floor plate 22. The lower end 431 of the pulling magnet 43J is brought into contact with the upper end 42 of the connecting pin 4P which is magnetically attracted. When the lower end 431 of the pulling magnet 43J comes into contact with the upper end 42 of the connecting pin 4P, the magnetic attraction force of the upper flange 42H of the connecting pin 4P to the steel plate member 22K disappears or decreases. The connecting pin 4P can be easily lifted to the raised position. In addition, in the raised position of the connecting pin 4P, the lower flange 43H of the connecting pin 4P is magnetically attracted to the steel plate member 22K, so even if the pulling magnet 43J is separated, the connecting pin 4P is held in the raised position. . Therefore, with the connecting pin 4P lifted to the raised position, the shaft portion 41 of the connecting pin 4P is held by the clamping plate 3K of the upper fixing mechanism 3 to easily connect the upper fixing mechanism 3 and the lower fixing mechanism 4. be able to.

Next, the upper fixing mechanism 3B and lower fixing mechanism 4B according to the second embodiment will be explained. That is, as shown in FIG. 10, the upper fixing mechanism 3B according to the second embodiment includes a pin shaft portion 33 that extends in the vertical direction and is formed to be vertically movable, and a lower end portion 331 of the pin shaft portion 33. The locking pin 3P includes a pair of locking plates 332 that are horizontally opposed to each other and are formed to be rotatable about the axis together with the protruding pin shaft portion 33. The locking plate 332 projects symmetrically with respect to the pin shaft portion 33. For example, by operating the operating lever 34 connected to the locking pin 3P along a Z-shaped guide groove 35 provided in the seat (portable object) 1, the locking pin 3P can be moved up and down or rotated. can be moved.

Further, the lower fixing mechanism 4B according to the second embodiment includes a pin insertion hole 4S formed in the floor surface 21 of the passenger room 2 corresponding to a plurality of fixing positions of the seat (transportable object) 1, and a pin insertion hole 4S formed in the floor surface 21 of the passenger compartment 2, and The opening/closing lid 4K formed to be able to open and close 4S faces the locking plate 332 fixed to the floorboard 22 constituting the floor surface 21 and rotated to the locking position, and restricts upward movement of the locking plate 332. It has a fixing metal fitting 4G. Here, the pin insertion hole 4S is formed in the fixture 4G. Further, the opening/closing lid 4K includes a pair of opening/closing plates 41K and 42K that open and close in parallel with the floorboard 22. The opening/closing plates 41K, 42K of the opening/closing lid 4K are always urged in the closing direction by a spring member (not shown). Note that a steel plate member 22K is laid on the floor plate 22, as in the first embodiment, and a cushion floor material 22S is laminated on the upper surface of the steel plate member 22K. Further, the floor surface 21 of the guest room 2 is provided with floor padding 23 that supports the floorboard 22. Further, a cam surface may be formed on the lower end portion 331 of the locking pin 3P, and cam contact surfaces may be formed on the opening/closing plates 41K, 42K of the opening/closing lid 4K. In that case, in conjunction with the downward movement of the locking pin 3P, the cam surface and the cam contact surface can be brought into contact with each other, and the opening/closing lid 4K can be moved to the open position.

Furthermore, the locking pin 3P can be inserted into the pin insertion hole 4S when the opening/closing lid 4K moves to the open position and the protruding direction of the locking plate 332 rotates in a direction perpendicular to the opening/closing direction of the opening/closing lid 4K. is formed. Therefore, after moving the opening/closing lid 4K of the lower fixing mechanism 4B to the open position, the lower end 331 of the pin shaft portion 33 of the locking pin 3P of the upper fixing mechanism 3B and the locking plate 332 are connected to each other. After inserting the locking pin 3P into the pin insertion hole 4S with the protruding direction rotated in a direction perpendicular to the opening/closing direction of the opening/closing lid 4K, the pin shaft portion 33 of the locking pin 3P is rotated, for example, 90 degrees around the axis. As a result, the locking plate 332 rotated to the locking position can be opposed to the fixture 4G fixed to the floorboard 22, and upward movement of the locking plate 332 can be restricted. Therefore, the upper fixing mechanism 3B and the lower fixing mechanism 4B can be easily connected.

Furthermore, when the locking plate 332 rotated to the locking position and the fixing metal fitting 4G face each other in the vertical direction, the fixing metal fitting 4G fixed to the floorboard 22 moves upward with the locking plate 332 to the locking pin 3P. Since movement is restricted, even if an inertia force is applied to the seat (transportable object) 1 due to activation of an emergency brake while the vehicle is running, the connection state between the upper fixing mechanism 3B and the lower fixing mechanism 4B can be stabilized. It can be held.

Further, the lower fixing mechanism 4B has a pin insertion hole 4S formed in the floor plate 22 and an opening/closing lid 4K formed to be able to open and close the pin insertion hole 4S, so when not used as the lower fixing mechanism 4B, , the pin insertion hole 4S can be covered by the opening/closing lid 4K. Therefore, the lower fixing mechanism 4B can be more easily installed at a required position on the floor surface 21 of the guest room 2 depending on various uses such as commuting, sightseeing, and events. Further, by shielding the pin insertion hole 4S with the opening/closing lid 4K, it is possible to prevent dust and the like from entering from outside the vehicle.

Further, as shown in FIG. 10, the opening/closing lid 4K is formed to be able to engage with the locking plate 332 that has been rotated to the locking position, and the fixing fittings 4G are capable of regulating upward displacement of the opening/closing lid 4K. It is formed. Therefore, even if an inertia force is applied to the seat (transportable object) 1 due to activation of an emergency brake while the vehicle is running, the locking plate 332 and the opening/closing lid 4K can be more reliably engaged with each other by the fixing bracket 4G. can be retained. Here, the fixture 4G has a substantially H-shaped cross-sectional structure that sandwiches the upper surface of the cushion floor material 22S and the lower surface of the floor padding 23 from above and below. In addition, the opening/closing lid 4K may be arranged above the fixture 4G and formed to be able to engage with the locking plate 332 when the fixture 4G is rotated to the locking position.

<Automation control mechanism>
Next, in the railway vehicle 10 according to the present embodiment, although it is possible to manually rearrange the seat (transportable object) 1 described above, the automation control mechanism 9 in the case of automation can be changed using FIG. 11. I will explain. FIG. 11 shows a block diagram of an automation control mechanism that automates the rearrangement of the seat (portable object) shown in FIG. 6.

As shown in FIG. 11, as one component of the automation control mechanism 9, the seat (portable object) 1 is equipped with a position sensor 71 that detects the position of the seat (portable object) 1 in the passenger compartment 2. , a collision avoidance sensor 72 that avoids collisions with other adjacent portable objects, a drive device 73 that connects or disconnects the upper fixing mechanisms 3 and 3B and the lower fixing mechanisms 4 and 4B, and A self-propelled device 74 for self-propelling a seat (transportable object) 1, and a first communication means 75 connected to a position sensor 71, a collision avoidance sensor 72, a drive device 73, and a self-propelled device 74, respectively. ing.

Note that the position sensor 71 is, for example, an optical sensor that can detect the relative position of the seat (portable object) 1 in the passenger compartment 2, or a GPS (Global Positioning) that can detect the absolute position of the seat (portable object) 1. System) receiver, etc. Further, the collision avoidance sensor 72 corresponds to an optical sensor, an ultrasonic sensor, or the like installed on the outer edge of the seat (portable object) 1. In addition, when the seat (portable object) 1 is equipped with the pulling magnet 43J, the second magnet 5, and casters 6, the drive device 73 moves the pulling magnet 43, the fixing electromagnet 5, and the casters 6.

In addition, as the other component of the automation control mechanism 9, the railway vehicle 10 includes a second communication means 85 configured to be able to transmit and receive data to and from the first communication means 75, and a second communication means 85 in the cabin 2 of the seat (portable object) 1. an input device 81 for inputting a layout pattern and a selection command for starting/stopping rearrangement by selecting one of the layout patterns; The drive device 73 and the self-propelled device 74 are operated based on the signal information from the storage device 82 that stores the arrangement pattern and selection command in the cabin 2, the position sensor 71, the collision avoidance sensor 72, and the storage device 82. The control device 8 includes a calculation device 83 that calculates control information to be controlled, and an output device 84 that outputs the control information calculated by the calculation device 83 to the second communication means 85.

Note that the arrangement pattern of the seats (transportable objects) 1 in the cabin 2 includes, for example, the seats 1a, 1b, 1c, This corresponds to the arrangement pattern in the guest room 2 such as 1d, 1e, table 1bb, and stand 1ee. Position signal information regarding each arrangement pattern is stored in the storage device 82.

When a layout pattern selection command is input to the input device 81, the calculation device 83 calculates necessary control information and outputs the control information from the output device 84 to the second communication means 85. Further, the control information outputted to the second communication means 85 is transmitted from the second communication means 85 to the first communication means 75, and the self-propelled device 74, which has received the necessary control information from the first communication means 75, is seated (possible). After moving the object) 1 to the fixed position corresponding to the selected arrangement pattern, the drive device 73, which has received the necessary control information from the first communication means 75, moves the upper fixing mechanisms 3, 3B, the lower fixing mechanisms 4, 4B, etc., to connect or disconnect the upper fixing mechanisms 3, 3B and the lower fixing mechanisms 4, 4B, etc.

Therefore, according to the present automation control mechanism 9, the movement and coupling or uncoupling operation of the seat (portable object) 1 is automatically performed according to the arrangement pattern of the seat (portable object) 1 in the passenger room 2. be able to. As a result, it becomes possible to save labor by moving, connecting or uncoupling the seat (transportable object) 1, and it becomes easy to change the position frequently. For example, in the same cabin 2, in the morning hours it is used as a commuter vehicle with a commuting layout pattern (see Figure 1), and in the afternoon hours it is used as a dining room with an eat-in corner layout pattern (see Figure 2). It can be used as a vehicle, and in the evening, it can also be used as a commuting vehicle in a commuting layout pattern (see Figure 1).

<Effect>
According to the railway vehicle 10 (10A, 10B, 10C, 10D, 10E) according to the present embodiment described in detail above, transportable objects (seats, tables, stands, storage shelves, wheelchair fixtures, two-wheel vehicle fixtures) equipment, other items that can be brought into the cabin) 1 is equipped with an upper fixing mechanism 3, 3B that fixes the position of the portable item 1 on the floor 21 side of the cabin 2. The is equipped with lower fixing mechanisms 4 and 4B that are formed so as to be connectable with the upper fixing mechanisms 3 and 3B and are arranged corresponding to a plurality of fixing positions of the portable object 1, so that it can be used for commuting, sightseeing, etc. The fixed position of the portable object 1 in the guest room 2 can be easily changed to a plurality of positions according to various uses such as events. That is, the lower fixing mechanisms 4 and 4B, which are formed so as to be connectable with the upper fixing mechanisms 3 and 3B, can be moved to multiple positions on the floor surface 21 of the guest room 2 depending on various uses such as commuting, sightseeing, event use, etc. It can be installed in advance. Then, from among the lower fixing mechanisms 4 and 4B installed in advance, a lower fixing mechanism 4 and 4B corresponding to the upper fixing mechanism 3 and 3B of the portable object 1 to be arranged according to the purpose is selected, and the upper fixing mechanism 4 and 4B are selected. , 3B and the lower fixing mechanisms 4, 4B need only be connected to each other. In addition, the upper fixing mechanisms 3 and 3B are provided on the floor 21 side of the transportable object (stool, etc.) 1, and the lower fixing mechanisms 4 and 4B are provided on the floor 21 of the passenger compartment 2, so the selected lower fixing mechanism 4 , 4B, the upper fixing mechanisms 3, 3B can be easily connected. Furthermore, since the lower fixing mechanisms 4 and 4B are provided on the floor surface 21 of the passenger compartment 2, it is easy to prevent them from protruding from the floor surface 21 when not in use.

Therefore, according to the present embodiment, the railway vehicle 10 (10A, 10B, 10C, 10D, 10E) can be provided.

Further, according to the present embodiment, the lower fixing mechanism 4 has a shaft portion in the position fixing hole 221 formed in the floor plate 22 that constitutes the floor surface 21 of the passenger room 2 corresponding to a plurality of fixing positions of the transportable object 1. Reference numeral 41 denotes a connecting pin 4P inserted so as to be movable up and down, and an upper flange 42H is formed on the upper end 42 of the shaft 41, which contacts the floor plate 22 flush with the lowered position of the connecting pin 4P. , the lower end portion 43 of the shaft portion 41 is formed with a lower flange portion 43H that comes into contact with the floor plate 22 in a state where the upper flange portion 42H protrudes upwardly from the floor plate 22 when the connecting pin 4P is in the raised position. The mechanism 3 includes a pair of clamping plates 3K (31K, 32K) that are inserted into the gap between the upper flange 42H of the connecting pin 4P and the floor plate 22 in the raised position and sandwich the shaft 41 from both sides. With the connecting pin 4P of the lower fixing mechanism 4 inserted into the position fixing hole 221 formed in the floorboard 22 of the passenger room 2 corresponding to the fixing position moved to the raised position, the clamping plate 3K of the upper fixing mechanism 3 The upper fixing mechanism 3 and the lower fixing mechanism 4 can be easily connected by sandwiching the shaft portion 41 of the connecting pin 4P.

In addition, when the shaft portion 41 of the connecting pin 4P is held between the holding plates 3K, the lower flange 43H of the connecting pin 4P comes into contact with the floor plate 22 to restrict the rising of the connecting pin 4P, and the upper flange of the connecting pin 4P 42 restricts the lifting of the clamping plate 3K, so even if an inertia force acts on the transportable object 1 due to an emergency brake being activated while the vehicle is running, the connection state between the upper fixing mechanism 3 and the lower fixing mechanism 4 will be maintained. can be held stably.

Further, the lower fixing mechanism 4 is a connecting pin 4P in which a shaft portion 41 is vertically movably inserted into a position fixing hole 221 formed in the floor plate 22. An upper flange 42H is formed on the lower end 43 of the shaft 41, and the upper flange 42H is formed above the floor plate 22 when the connecting pin 4P is in the raised position. Since the lower flange portion 43H is formed so as to come into contact with the floor plate 22 in a protruding state, the connecting pin 4P can be formed compactly. Therefore, the lower fixing mechanism 4 can be more easily installed at a required position on the floor surface 21 of the guest room 2 depending on various uses such as commuting, sightseeing, and events.

Further, according to the present embodiment, the connecting pin 4P is a magnet body 4PJ having magnetic poles (N, S) facing each other at the upper end 42 and the lower end 43, and the connecting pin 4P is magnetically attracted to the floor plate 22. Since the steel plate member 22K is installed and the position fixing hole 221 is formed in the steel plate member 22K, when the connecting pin 4P (4PJ) is used as the lower fixing mechanism 4, the upper steel plate member 22K of the floor plate 22 is installed. When the pulling magnet 43J is brought into contact with the upper end 42 of the connecting pin 4P (4PJ) to which the flange 42H is magnetically attracted, the magnetic attraction force of the upper flange 42 of the connecting pin 4P (4PJ) to the steel plate member 22K disappears. Alternatively, the connecting pin 4P (4PJ) can be easily lifted to the raised position together with the pulling magnet 43J. In addition, in the raised position of the connecting pin 4P (4PJ), the lower flange 43H of the connecting pin 4P (4PJ) is magnetically attracted to the steel plate member 22K, so even if the pulling magnet 43J is separated, the connecting pin 4P ( 4PJ) is held in the raised position. Therefore, with the connecting pin 4P (4PJ) lifted to the raised position, the shaft portion 41 of the connecting pin 4P (4PJ) is held by the clamping plate 3K of the upper fixing mechanism 3, and the upper fixing mechanism 3 and the lower fixing mechanism 4 can be easily connected.

Furthermore, when the connecting pin 4P (4PJ) is not used as the lower fixing mechanism 4, the upper flange 42H of the connecting pin 4P (4PJ) remains magnetically attracted to the steel plate member 22K of the floor plate 22. It is possible to easily avoid the occurrence of abnormal noise when the vehicle is running. In addition, the upper flange 42H of the connecting pin 4P (4PJ) magnetically attracts the steel plate member 22K of the floor plate 22 and closes the position fixing hole 221 formed in the steel plate member 22K, thereby preventing dust from entering from outside the vehicle. It can be regulated.

Further, according to the present embodiment, the movable object 1 is formed on the floor surface side so as to be retractable from the lower end 11 of the portable object 1, and is magnetically attracted to the steel plate member 22K when placed at a fixed position. Since the second magnet body 5 is provided at a different position from the upper fixing mechanism 3, when the upper fixing mechanism 3 and the lower fixing mechanism 4 are connected, the second magnet body 5 is attached to the steel plate member 22K of the floor plate 22. By magnetically adsorbing the movable object 1, rattling and chattering noise of the portable object 1 can be suppressed.

Furthermore, according to the present embodiment, the floor side of the portable object 1 is provided with casters 6 that are formed so as to be able to appear and retract from the lower end 11 of the portable object 1 at a position different from the upper fixing mechanism 3. Therefore, when the portable object 1 is heavy, the casters 6 are made to protrude from the lower end 11 of the portable object 1, and the portable object 1 can be easily moved. Furthermore, since the casters 6 are formed so as to be able to move in and out from the lower end 11 of the portable object 1, when the portable object 1 is placed at a fixed position, the casters 6 cannot be stored in the lower end 11 of the portable object 1. This eliminates the need to apply a load due to the weight of the transportable object 1 to the floorboard 22.

Further, according to the present embodiment, the upper fixing mechanism 3B includes a pin shaft portion 33 that extends in the vertical direction and is formed to be vertically movable, and a lower end portion 331 of the pin shaft portion 33 that faces the lower end portion 331 of the pin shaft portion 33 in the horizontal direction. The locking pin 3P has a pair of locking plates 332 that are formed to be rotatable around the axis together with the protruding pin shaft portion 33, and the lower fixing mechanism 4B is configured to lock the portable object 1 at a plurality of fixing positions. A pin insertion hole 4S formed in the floor surface 21 of the guest room 2 correspondingly to the pin insertion hole 4S, an opening/closing lid 4K formed to be able to open and close the pin insertion hole 4S, and a lid 4K that is fixed and locked to the floor plate 22 that constitutes the floor surface 21. It has a fixing metal fitting 4G that faces the locking plate 332 rotated to the position and restricts upward movement of the locking plate 332. Furthermore, the locking pin 3P can be inserted into the pin insertion hole 4S when the opening/closing lid 4K moves to the open position and the protruding direction of the locking plate 332 rotates in a direction perpendicular to the opening/closing direction of the opening/closing lid 4K. Since the opening/closing lid 4K of the lower fixing mechanism 4B is moved to the open position, the lower end 331 of the pin shaft portion 33 of the locking pin 3P of the upper fixing mechanism 3B and the locking plate 332 are After inserting the locking plate 332 into the pin insertion hole 4S in a state in which the protruding direction thereof is rotated in a direction perpendicular to the opening/closing direction of the opening/closing lid 4K, the locking pin 3P is rotated around the pin shaft portion 33 of the locking pin 3P, for example. By rotating the locking plate 332 by 90 degrees, the locking plate 332 rotated to the locking position can be opposed to the fixture 4G fixed to the floorboard 22, and upward movement of the locking plate 332 can be restricted. Therefore, the upper fixing mechanism 3B and the lower fixing mechanism 4B can be easily connected.

Furthermore, when the locking plate 332 rotated to the locking position and the fixing metal fitting 4G face each other in the vertical direction, the fixing metal fitting 4G fixed to the floorboard 22 moves upward with the locking plate 332 to the locking pin 3P. Since movement is restricted, even if an inertia force is applied to the transportable object 1 due to activation of an emergency brake while the vehicle is running, the connection state between the upper fixing mechanism 3B and the lower fixing mechanism 4B can be stably maintained. can be done.

Further, the lower fixing mechanism 4B has a pin insertion hole 4S formed in the floor plate 22 and an opening/closing lid 4K formed to be able to open and close the pin insertion hole 4S, so when not used as the lower fixing mechanism 4B, , the pin insertion hole 4S can be covered by the opening/closing lid 4K. Therefore, the pin insertion hole 4S of the lower fixing mechanism 4B can be installed at a required position on the floor surface 21 of the guest room 2 depending on various uses such as commuting, sightseeing, and events, while shielding the pin insertion hole 4S of the lower fixing mechanism 4B. Further, by shielding the pin insertion hole 4S with the opening/closing lid 4K, it is possible to prevent dust and the like from entering from outside the vehicle.

Further, according to the present embodiment, the lower fixing mechanism 4B has a fixing metal fitting 4G that is fixed to the floor plate 22 and restricts upward displacement of the opening/closing lid 4K, and the pin insertion hole 4S is formed in the fixing metal fitting 4G. Therefore, even if an inertia force is applied to the transportable object 1 due to activation of an emergency brake or the like while the vehicle is running, the locking plate 332 of the locking pin 3P and the opening/closing lid 4K remain engaged with each other. 4G makes it possible to hold the upper fixing mechanism 3B and the lower fixing mechanism 4B more stably.

Further, according to the present embodiment, a steel plate member 22K that can be magnetically attracted is laid on the floor plate 22, and a steel plate member 22K that can be attached to the floor of the portable object 1 is formed so as to be able to appear and retract from the lower end 11 of the portable object 1. , the second magnet body 5, which is formed to be able to magnetically attract the steel plate member 22K when placed at the fixed position, is provided at a different position from the upper fixing mechanism 3B, so that the upper fixing mechanism 3B and the lower fixing mechanism 4B, the second magnet body 5 magnetically attracts the steel plate member 22K of the floor plate 22, thereby making it possible to suppress rattling and chattering noise of the portable object 1.

Further, according to the present embodiment, the floor side of the portable object 1 is provided with casters 6 formed so as to be able to appear and retract from the lower end 11 of the portable object 1 at a position different from the upper fixing mechanism 3B. Therefore, when the portable object 1 is heavy, the casters 6 are made to protrude from the lower end 11 of the portable object 1, and the portable object 1 can be easily moved. Furthermore, since the casters 6 are formed so as to be able to move in and out from the lower end 11 of the portable object 1, when the portable object 1 is placed at a fixed position, the casters 6 cannot be stored in the lower end 11 of the portable object 1. This eliminates the need to apply the load due to the weight of the portable object 1 to the floorboard 22 via the casters 6.

Further, according to the present embodiment, the portable object 1 is provided with a position sensor 71 that detects the position of the portable object 1 in the passenger compartment 2, and a position sensor 71 that detects the position of the portable object 1 in the passenger compartment 2 to avoid collision with another adjacent portable object 1. The collision avoidance sensor 72, the drive device 73 that connects or disconnects the upper fixing mechanisms 3 and 3B, the self-propelled device 74 that moves the portable object 1 in the passenger compartment 2, and the position sensor 71 collide with each other. It includes an avoidance sensor 72, a first communication means 75 connected to a drive device 73, and a self-propelled device 74, respectively. In addition, the railway vehicle 10 includes a second communication means 85 formed to be able to transmit and receive data to and from the first communication means 75, and one of the arrangement patterns of the transportable objects 1 in the cabin 2 and the arrangement pattern selected from the arrangement pattern. an input device 81 for inputting selection commands for starting and stopping rearrangement; a storage device 82 for storing the arrangement pattern of the portable objects 1 in the cabin 2 and the selection commands input in advance from the input device 81; A calculation device 83 calculates control information for controlling the drive device 73 and the self-propelled device 74 based on each signal information from the position sensor 71, the collision avoidance sensor 72, and the storage device 82; The control device 8 includes an output device 84 that outputs control information to a second communication means 85.

When a selection command is input to the input device 81, the calculation device 83 calculates necessary control information and transmits the control information to the first communication means 75 via the output device 84 and the second communication means 85. After receiving the necessary control information from the first communication means 75, the self-propelled device 74 moves the portable object 1 to a fixed position corresponding to the selected arrangement pattern, and then transmits the necessary control information from the first communication means 75. The drive device 73 that receives the drive operates the upper fixing mechanisms 3, 3B to connect or disconnect the upper fixing mechanisms 3, 3B and the lower fixing mechanisms 4, 4B, so that the arrangement pattern of the portable objects 1 in the cabin 2 is changed. Accordingly, the movement of the portable object 1 and the connection or disconnection operation between the upper fixing mechanisms 3, 3B and the lower fixing mechanisms 4, 4B can be automatically performed. Therefore, it becomes possible to save manpower when moving, connecting, or uncoupling the transportable objects 1, and it becomes easy to change the positions frequently. For example, in the same cabin 2, in the morning hours it is used as a commuter vehicle with a layout pattern for commuting, in the afternoon it is used as a dining vehicle with an eat-in corner layout pattern, and then again in the evening hours. It can also be used as a commuting vehicle with a commuting layout pattern.
