[0013]

According to the first aspect of the present invention, the seat body accommodating the child occupant has the seat body locked to the support member by the first locking means, and the first locking means is centered by the second locking means. Is locked in a turning-prevented state with respect to the supporting member. Here, the first locking means makes the seat body and the support member detachable along a substantially linear direction inclined at a predetermined angle with respect to the horizontal direction, and the seat body and the support member in directions other than the detachment direction in the mounted state. Prevent relative movement of (for example,
The other part is inserted and arranged in a straight groove provided at a predetermined angle to the horizontal direction in one of the seat body and the support member), so that the seat body is simply straightened along the attaching / detaching direction. By attaching to the support member, the first locking means is locked (in one operation), so that the relative movement of the seat body with respect to the support member in the horizontal direction and the vertical direction is limited, and the sheet body usually falls off from the support member. Never. On the other hand, even when an inadvertent load is applied, since the second locking means prevents the seat body from turning around the first locking means with respect to the support member, the seat body falls off from the support member. Is eliminated. In addition, turning around other than the first locking means (for example, turning about the second locking means)
Is prevented by the first locking means for restricting the vertical movement of the seat body. In addition, each locking means in this case is not limited to the structure in which the load of the seat body is supported by the support member, and the load of the sheet body is supported by the support member by another component, and the locking means simply moves the seat body. The structure may be a blocking structure.

According to the second aspect of the present invention, the second locking means enables the seat body to move relative to the support member in a direction intersecting with the turning direction. Is locked to the support member, and the lock is released by the movement to the other side, so that the lock and release operations can be performed simply by the relative movement of the seat body to the support member. In particular, if the direction of this relative movement and the above-mentioned attaching / detaching direction are substantially the same direction (including the case of being substantially parallel), the first locking means and the second locking means are locked by one operation. Accordingly, the operation of attaching and detaching the seat body to and from the support member is further facilitated.

According to the third aspect of the present invention, the first locking portion provided at the front of the seat body is inserted into the first support portion of the bogie, and the turning preventing means is locked by the relative movement between the seat body and the bogie. Let it. With this relative movement, the second locking portion is locked by the second support portion, and the load of the seat body is supported by the bogie. Here, the first support portion into which the first locking portion is inserted is formed in a concave shape along a substantially straight line direction inclined at a predetermined angle with respect to the horizontal direction, and the seat body (first locking portion) is formed in the substantially straight line direction. The seat body can be inserted in the horizontal direction and the vertical direction with respect to the bogie simply by inserting the first locking portion into the first supporting portion along the above-mentioned substantially straight line (in one operation). The relative movement of the vehicle body is limited, and the seat body does not fall off the carriage due to the ordinary movement of the carriage. On the other hand, even when an inadvertent load is applied due to, for example, an abrupt stop of the bogie, the turning prevention means makes the seat main body incapable of turning around the first locking portion in the antigravity direction with respect to the bogie. Is securely supported by the trolley. In addition, the turning around the portion other than the first locking portion is prevented by the first support portion that restricts the relative movement of the seat body in the vertical direction. In addition, since the turning prevention means enables relative movement of the bogie and the seat body in a direction intersecting the turning direction, mounting and detaching operations of the seat body can be performed by this relative movement. In particular, if the direction of this relative movement and the above-mentioned substantially straight line direction are made substantially the same direction (including the case of being substantially parallel), each locking portion is locked by one operation, and the seat body with respect to the bogie is moved. The attachment / detachment operation is further facilitated.

According to the fourth aspect of the present invention, the seat body side portion of the turning preventing means and the second locking portion are opposed to each other so that the bogie side portion of the turning preventing means and the second support portion can be inserted therebetween. Therefore, the turning prevention means, the second locking portion, and the second support portion are formed with a simple structure. In particular, if the bogie-side portion of the turning preventing means and the second support portion are integrally formed, the structure becomes simpler.

In the invention according to claim 5, the first locking portion as the rotating body and the first supporting portion as the concave portion correspond to each other.
The seat body can be mounted on the bogie while supporting its own weight on the rotating body and rotating the rotating body, so that the mounting operation is easy.

In the invention according to claim 6, the locking means for securely attaching the seat body to the carriage is provided, so that the attachment is ensured.

The seat body 12 and the buggy car 100 are inserted into the 118C to fix the seat body 12 and the buggy car 100. Note that the lock pin 152 is moderately held lightly with moderation between a state in which it protrudes to the passage interval 72 and a state in which it retreats from the protrusion, so that the user can easily operate it.

As shown in FIGS. 8 and 17, the mounting block 124 is formed with a slope 124A to which the periphery of the seat body 12 approaches when the seat body 12 is securely mounted on the buggy car 100. The slope 124A is formed on the slope 124A. A coloring tape 157 constituting a confirmation mark is attached. This colored tape 157 is applied to the
Is securely covered by the edge of the sheet body 12 in a state where the colored tape 157 is securely attached. When the colored tape 157 is not securely attached, the colored tape 157 is not concealed by the edge and can be viewed. The attachment state can be determined.

(Operation of the Embodiment) The seat body 12 is mounted on the vehicle shown in FIGS.
In order to move the tongue plate 34 to 00, the release button 32A of the buckle 32 is pressed to release the tongue plate 34 from the buckle 32. Thereby, the shoulder belt 36 and the waist belt 38 can be removed from the state of being wound around the seat body 12. Here, the seat body 12 holds the edge 12A of the seat body 12 or pulls out the middle part of the carrying rope 46 in the imaginary line state of FIG. It can be carried in a state of being restrained with. As shown in FIG. 10, the roller 64 at the front end of the sheet body 12 is inserted into the U-shaped recess 110A of the lower support block 110, and the support protrusion of the upper support block 118 is moved through the passage 72 between the brackets 56 and 58. The support state shown in FIG. 9 is obtained by corresponding the inside of the portion 118A.

In this case, the roller 64 directly contacts the U-shaped recess 11.
0A, but may be temporarily mounted on the inclined portion 110B, and in this state, the extension portion 68 of the slide projection 68 may be inserted.
A is a receiving surface 118F which is the upper end of the support protrusion 118A.
To be placed. By this placing operation, the sheet body 12
Is temporarily supported by the lower support block 110 and the upper support block 118, respectively.
The roller 64 is guided to the U-shaped recess 110A while rolling on B, and the extension 64A is moved in the direction of arrow D while guiding the receiving surface 118F of the support projection 118A, whereby the roller 64 is moved to the bottom of the U-shaped recess 110A. , The passage interval 72 is in a state of accommodating the support protrusion 118A.

As a result, the roller 64 is only allowed to move in the direction opposite to the arrow Q direction, and the brackets 56 and 58 are only allowed to move in the direction opposite to the arrow D direction. Normal buggy car 10
Such a load in the direction of lifting the seat body 12 is not applied by the zero movement operation, and the child occupant seat 10 is securely supported by the buggy car 100. Further, when the buggy car 100 suddenly stops while moving, a load acts on the roller body 64 in the cross direction (the direction of the arrow E in FIG. 1) in which the sheet body 12 is substantially orthogonal to the direction of the arrow D. This load is applied when the locking projections 70 correspond to the bottom surface 118 </ b> G of the upper support block 118.
Since the child vehicle seat 10 is supported at 0, the child vehicle seat 10 does not separate from the lower support block 100.

Further, by operating the knob 154 shown in FIG. 3 to protrude the lock pin 152 from the passage interval 72 and insert the lock pin 152 into the through hole 118C of the upper support block 118, the child vehicle seat 10 is Movement in the direction opposite to the direction of arrow A in FIG. 2 and in the direction opposite to the direction of arrow D in FIG.

As described above, when the roller 64 is inserted into the bottom of the U-shaped concave portion 110A and the supporting projection 118A does not correspond to the passage interval 72, the child occupant seat 10 has an edge as shown by an imaginary line in FIG. Since the upper end of the portion 12A is placed away from the coloring tape 157 and the coloring tape 157 is visible, the user can easily determine that the user is not in a reliable supporting state. In addition to the colored tape 157, other alerting display means such as a dial may be provided on the slope 124.
A, etc., is attached to a part of the buggy car 100 by sticking or the like, or a display means for alerting such as coloring, letters, irregularities, etc. is directly given to a part of the buggy car 100 by hot stamping, printing, spraying or the like. You may.

FIG. 18 shows a state in which another type of child occupant seat 200 is attached in place of the child occupant seat 10. The child occupant seat 200 is for accommodating a child occupant who is older than the child occupant seat 10, and is basically similar to the child occupant seat 10 in that the child occupant is accommodated and restrained by a seat belt. The same is true.
3 is different from the child occupant seat 200 in that the lock pin 152 of the seat body 12 in FIG. . In this child occupant seat 200, the slide projection 68 and the locking projection 70 of the bracket 56, the bracket 58 are omitted. Therefore, in this child occupant seat 200, when the lock pin 152 is slid in the direction of arrow F or the direction of arrow G when the lock pin 152 is attached to the upper support block 118 in FIG. The pushing force is received by the slope, and it is drawn into the bracket 56 and the bracket 58 against the urging force. When the lock pin 152 moves to the position corresponding to the through hole 118C, the lock pin 152 projects again by the urging force and is inserted into the through hole 118C, and a secure fixed state is obtained.

In the above embodiment, the roller 64 and the slide projection 68 allow the weight of the seat body 12 to be reduced by the buggy car 1.
The seat body 12 has a function of supporting the buggy car 100 in a portion different from these portions, while having a role of supporting both when the seat body 12 is supported by an inadvertent load. Alternatively, a configuration may be adopted in which the support is provided only when an inadvertent load such as the detachment of the seat body 12 is applied. U into which the roller 64 is inserted
The U-shaped recess 110A does not necessarily have to be U-shaped, and other recesses such as a V-shape, a U-shape, and a dish-shape can be widely applied as long as the recesses can receive the roller 64. Further, the lock pin 152 in the above embodiment may be provided as needed, and may be omitted when the seat body 12 is securely attached to the buggy car 100 by other components. In addition, this lock pin 152
In addition, other locking means such as a cam, a screw, and a lock lever can be applied to securely fix the seat body 12 to a buggy car or the like.

Further, in the above embodiment, the supporting structure in the case where the child occupant seat 10 is mounted on the buggy car 100 has been described. The present invention can be widely applied to the case where the vehicle is supported. In this case, a component having the same function as that of the lower support block 110 or the upper support block 118 provided in the buggy car 100 may be provided in advance on the support member.
