That is, the second table arm 62 is fixed to the first table arm 61. As shown in FIG. 10, by releasing the locking state of the stopper 65 to the first table arm 61, the second table arm 62 becomes rotatable relative to the first table arm 61. Since the second table arm 62 is rotatable, the table arm 6 can be folded forward into a horizontal state, as shown in FIG.

When folding the table arm 6 configured as described above, the backrest 3 is first folded as shown in FIG. 3, and then the stopper 65 is locked to the first table arm 61 as shown in FIGS. Release. Then, the second table arm 62 is rotated forward about the link member 63, and the table arm 6 is folded into a horizontal state as shown in FIGS. 5 and 11. In the state shown in FIG. 5, the first table arm 61 and the second table arm 62 are located at a lower position than the armrest 4, and the table 5 is located near the armrest 4 and parallel to the backrest 3.

As shown in FIG. 12, the bogie 8 is loaded into the cabin of a passenger train and transported together with luggage 18. The trolley 8 has a base plate 80 positioned in a space created above the backrest 3, table arm 6, and table 5 when the backrest 3 and table arm 6 are folded forward. It includes four legs 82 hanging down from the four corners, wheels 83 attached to the lower end of each leg 82, and a rotating body 93 and an elevating body 97 that restrict movement of the trolley 8.

The base plate 80 is a rectangular plate having a longitudinal direction and a lateral direction. The base plate 80 is positioned in the space with its longitudinal direction aligned with the front-rear direction of the seat device 1. A handle 81 is attached to one end and the other end of the base plate 80 in the longitudinal direction. The cargo 18 is placed on the base plate 80 and positioned in the above-mentioned space, and is transported along with the cart 8 as it is.

Two of the legs 82 at one longitudinal end of the base plate 80 are positioned at the rear of the seat device 1 , and two legs at the other longitudinal end of the base plate 80 are positioned at the front of the seat device 1 .

As shown in FIG. 15, these pins 87 and metal fittings 88 function as locks when connecting a plurality of carts 8 to each other.

Between the two legs 82 on the other end of the base plate 80 in the longitudinal direction, three reinforcing parts 84, 85, 86 extending in the widthwise direction of the base plate 80 in the shape of a rod are bridged between the two legs 82 on the other end side in the longitudinal direction of the base plate 80. has been done. Further, a pin 87 is attached to one of these legs 82, and a metal fitting 88 is attached to the other. Similar to the one end side, these pins 87 and metal fittings 88 function as locks when connecting a plurality of carts 8 to each other.

The reinforcing portions 84, 85, 86 described above are not provided between the leg 82 on one longitudinal end side of the base plate 80 and the leg 82 on the other end side. That is, since this bogie 8 is intended to be slid from the aisle of a passenger train toward the seat device 1 side with the wheels 83 in contact with the floor, there is a space in which it will not interfere with the seat device 1 when it is slid. A leg 82 on one end side and a leg 82 on the other end side are provided so as to be formable. Specifically, "a space is provided so that it can be formed" means that the space is formed or not formed depending on the positions of the rotating body 93 and the elevating body 97.

All four wheels 83 employ swing casters with rotation stoppers. Since the trolley 8 can be connected to the seat using the rotating body 93 and the elevating body 97, there is no need to use the rotation stopper of the wheel 83 when it is connected to the seat, but at other times the rotation of the wheel 83 is A stopper can be used to prevent the carriage 8 from moving.

As shown in FIGS. 12 and 16, the rotating body 93 includes a flat plate 90 rotatably attached to the reinforcing portion 85 via a pair of torque hinges 89, a first rib 91 protruding from one surface of the flat plate 90, and A second rib 92 is provided. The rotation center axis of the rotation body 93 is parallel to the transverse direction of the base plate 80. The flat plate 90 is formed into a rectangular plate shape whose long sides are parallel to the transverse direction of the base plate 80. The first rib 91 and the second rib 92 are parallel to each other and extend in the lateral direction of the base plate 80.

As shown in FIGS. 16 and 17, the rotating body 93 located at the rear of the seat device 1 rotates approximately 90 degrees forward from a state in which the flat plate 90 is in the vertical direction. By rotating in this way, as shown in FIG. 19, the beam portion 79 of the backrest 3 is engaged between the first rib 91 and the second rib 92, and the flat plate 90 is moved between the pair of arm portions 71. engage. This restricts the movement of the truck 8 in the front-rear direction and the left-right direction.

In this example, one rotating body 93 is provided at one end of the base plate 80 in the longitudinal direction, and one at the other end. As shown in FIG. 18, the rotating body 93 used when connecting the trolley 8 to the seat device 1 is the rotating body 93 located at the rear of the seat device 1, and the rotating body 93 located at the front is not used. The rotating body 93 located at the front is used when the seat device 1 is in the opposite direction.

The elevating body 97 is formed into a plate shape extending in the longitudinal direction of the base plate 80. Elongated holes 98 extending in the vertical direction are formed at both ends of the elevating body 97 in the longitudinal direction. A hole 99 is formed in the center of the elevating body 97 for inserting a hand during elevating and lowering operations. Further, a pin 94 positioned within the elongated hole 98 is attached to the leg 82 on one longitudinal end side of the base plate 80 and the leg 82 on the other end side in the longitudinal direction.

The elevating body 97 can be raised and lowered between an upper position shown in FIGS. 14 and 16 and a lower position shown in FIGS. 15 and 18. The upper position is directly below the base plate 80 and is higher than the armrest 4. That is, the upper position is a position where the elevating body 97 does not interfere with the armrest 4 when the trolley 8 is slid from the aisle to the seat device 1 side. The lower position is a position where the elevating body 97 interferes with the armrest 4 when the trolley 8 is slid from the aisle to the seat device 1 side.

As shown in FIGS. 17 and 18, such an elevating body 97 is inserted between the table 5 and the armrest 4 by being lowered from the upper position to the lower position. This restricts the movement of the cart 8 in the left and right direction. Note that, as described above, it is possible to restrict the movement of the cart 8 in the front and rear directions and the movement in the left and right directions using only the rotating body 93, but by further using the elevating body 97, the movement of the cart 8 in the left and right direction can be restricted more strictly. Can be regulated.

In addition, the cart 8 of this example has a hook-and-loop fastener 95 attached to the upper end surface of the lifter 97 and a hook-and-loop fastener 96 attached to the lower surface of the base plate 80 as maintenance means for maintaining the lifter 97 in the upper position. , is equipped with. When the hook-and-loop fasteners 95 and 96 stick together, the elevating body 97 is maintained at the upper position. Magnetic catches can also be used instead of these hook-and-loop fasteners 95, 96.

In this example, one elevating body 97 is provided on one end of the base plate 80 in the transverse direction, and one on the other end. When connecting the trolley 8 to the seat device 1, both lifting bodies 97 may be inserted between the table 5 and the armrest 4 on the aisle side, and between the table 5 and the armrest 4 on the window side, or only one of them may be inserted. May be used. From the viewpoint of workability, it is preferable to use the elevator 97 on the passage side.

In a state in which the flat plates 90 of the pair of rotating bodies 93 are in the vertical direction and in a state in which the pair of elevating bodies 97 are in the upper position, the truck 8 has legs 82 on one longitudinal end side of the base plate 80 and legs on the other end side in the longitudinal direction. 82, a space is formed that does not interfere with the seat device 1 when the trolley 8 is slid. Further, the width of the trolley 8 is smaller than the width of each seat of the seating device 1. Therefore, the trolley 8 connected to the seat of the seating device 1 by the rotating body 93 and the elevating body 97 is prevented from protruding into the adjacent seat or the aisle side.
