[0014] The child car seat and its installation / removal method according to the present invention will be described in detail below with reference to the drawings. In this embodiment, the longitudinal direction (front and rear) refers to the front and rear directions of the vehicle, and the left and right directions and horizontal direction refer to the direction between the vehicle doors, in other words, the direction perpendicular to the longitudinal direction of the vehicle. The child car seat of the present invention comprises a seat 12 on which an infant or toddler sits, a base 14 that is attached to a vehicle seat and supports the seat 12, and a sliding mechanism between the seat 12 and the base 14 that moves the seat 12 horizontally relative to the base 14, passing through the fixed position of the seat 12 and the attached or removed position. The sliding mechanism has a T-groove 20 formed along the horizontal direction, a recess 22 provided on the main surface of the T-groove 20 at the fixed position of the seat 12, a flanged member 30 that fits into the T-groove 20, and a protrusion 32 that is biased to protrude from the main surface of the flanged member 30 toward the recess 22, thereby engaging and fixing the seat 12 to the base 14.

[0015] Example 1 FIG. 1 is a perspective view of the seat of the child car seat of the first embodiment, FIG. 2 is a side view of the seat, FIG. 3 is a perspective view of the base, and FIG. 4 is a side view of the base. FIG. 5 is a perspective view of the seat of the child car seat of the first embodiment attached to the base. FIG. 6 is a front cross-sectional view of the seat of the child car seat of the first embodiment attached to the base. FIG. 7 is a perspective view of the child car seat of the first embodiment during sliding movement. FIG. 8 is a front cross-sectional view of the child car seat of the first embodiment during sliding movement. FIG. 9 is a perspective view of the fixing position of the child car seat of the first embodiment. FIG. 10 is a front cross-sectional view of the fixing position of the child car seat of the first embodiment. The child car seat shown in the first embodiment has a flanged member 30 and a protrusion 32 on the seat 12, and a T-slot 20 and a recess 22 on the base 14. The T-slot 20 has a T-shaped cross section and is formed on the top surface of the base 14 so as to extend horizontally across both side surfaces of the base 14. A recess 22 is provided at the center of the T-slot 20, where the sheet 12 is fixed. The flanged member 30 is a rectangular member with a T-shaped cross section, and is provided with a flange that fits into the T-slot 20. A protrusion 32 is provided in the center of the flanged member 30. The protrusion 32 is biased so as to protrude from the underside of the sheet 12 toward the recess 22 of the base 14, thereby engaging and fixing the sheet 12 to the base 14. Operating members 34 are provided on both side surfaces of the seat 12. The operating members 34 are operating levers that are connected to the protrusions 32 and can reduce the amount of protrusion of the protrusions 32 from the underside of the seat 12 to zero by operating them in the opposite biasing direction. In this embodiment, the operating members 34 can reduce the amount of protrusion of the protrusions 32 to zero by operating either one of them.

[0016] In this type of child car seat, the protrusion amount of the convex portion 32 is set to zero by operating one of the operating members 34 provided on the side of the seat 12. With the operating member 34 still operated, the seat 12 is lifted and moved to the side of the base 14 fixed to the vehicle seat (see FIGS. 5 and 6). Then, the flanged member 30 is fitted into the T-slot 20 from one of the sides of the T-slot 20 of the base 14, and then moved horizontally. After the lower surface of the flanged member 30 contacts the upper surface of the T-slot 20, the convex portion 32 remains pressed against the upper surface of the T-slot 20 even if the operating member 34 is released (see FIGS. 7 and 8). When the seat 12 is then slid horizontally to the fixed position in the center of the base 14, the biased convex portion 32 protrudes and fits into the recess 22 at the fixed position, and the seat 12 can be fixed to the base 14 (see FIGS. 9 and 10). When removing the sheet 12, the protrusion amount of the convex portion 32 becomes zero regardless of which operating member 34 is operated, and the sheet 12 is slid horizontally in a state where the convex portion 32 is disengaged from the concave portion 22. During the sliding movement, even if the operating member 34 is released, the convex portion 32 remains pressed against the upper surface of the T-slot 20. If the sheet 12 is slid horizontally in this state to the attachment or removal position on the side of the T-slot 20, the engagement between the T-slot 20 and the flanged member 30 will be released, and the sheet 12 can be removed.

[0017] Example 2 FIG. 11 is a perspective view of the base of the child car seat of the second embodiment. FIG. 12 is a perspective view of the seat of the child car seat of the second embodiment attached to the base. FIG. 13 is a front cross-sectional view of the seat of the child car seat of the second embodiment attached to the base. FIG. 14 is a perspective view of the fixing position of the child car seat of the second embodiment. FIG. 15 is a front cross-sectional view of the fixing position of the child car seat of the second embodiment. The child car seat shown in the second embodiment differs from that of the first embodiment in the configuration of the T-slot 20A of the base 14. The other configurations are the same as those of the first embodiment, and detailed explanations will be omitted. The T-slot 20A of the second embodiment has recessed grooves 24 at both ends into which the flanged member does not fit. The T-slot 20A is sandwiched between the recessed grooves 24 at both ends, and the side of the seat 14 is formed in a recessed shape without a flange. In this type of child car seat, the protrusion of the convex portion 32 is set to zero by operating one of the operating members 34 provided on the side of the seat 12. While the operating member 34 is still operated, the seat 12 is lifted and moved to one of the recessed grooves 24 of the base 14 fixed to the vehicle seat (see FIGS. 12 and 13). The lower surface of the flanged member 30 is then brought into contact with the upper surface of the recessed groove 24. After the lower surface of the flanged member 30 contacts the upper surface of the T-slot 20A, the protrusion 32 remains pressed against the upper surface of the T-slot 20A even if the operating member 34 is released. By sliding the flanged member 30 horizontally from the recessed groove 24 toward the T-slot 20A, the flanged member 30 can be easily fitted into the T-slot 20A. By continuing to slide the flanged member 30 horizontally to the fixed position at the center of the base 14, the biased protrusion 32 protrudes and fits into the recessed portion 22 at the fixed position, thereby fixing the seat 12 to the base 14 (see FIGS. 14 and 15). When removing the sheet 12, whichever operating member 34 is operated, the protrusion amount of the convex portion 32 becomes zero, and the sheet 12 is slid horizontally in a state where the convex portion 32 is disengaged from the concave portion 22. During the sliding movement, even if the operating member 34 is released, the convex portion 32 remains pressed against the upper surface of the T-slot 20A. If the sheet 12 is slid horizontally in this state up to the concave groove 24, the T-slot 20A and the flanged member 30 will disengage, and the sheet 12 can be removed.

Figure 17 is a perspective view of the fixing position of the child car seat of the third embodiment. Figure 18 is a front cross-sectional view of the fixing position of the child car seat of the third embodiment. Figure 19 is a perspective view of the fixing position of the child car seat of the third embodiment and another recess. Figure 20 is a front cross-sectional view of the fixing position of the child car seat of the third embodiment and another recess. The child car seat shown in the third embodiment differs from the first embodiment in the configuration of the recess 22A of the base 14. The other configurations are the same as those of the first embodiment, and detailed explanations will be omitted. The recesses 22A of the third embodiment are provided in multiple linear positions (three in Figures 16-20) along the longitudinal direction of the T-groove 20B. This type of child car seat can be attached and detached by the same operation as in Example 1. When the operating member 34 is released during horizontal sliding, the convex portions 32 protrude from the recesses 22A, allowing the seat to be fixed at any of the recesses 22A positions.

FIG. 22 is a perspective view of the fixing position of the child car seat of the fourth embodiment. FIG. 23 is a front cross-sectional view of the fixing position of the child car seat of the fourth embodiment. FIG. 24 is a perspective view of the child car seat of the fourth embodiment during sliding movement. FIG. 25 is a front cross-sectional view of the child car seat of the fourth embodiment during sliding movement. The child car seat shown in the fourth embodiment differs from the first embodiment in that a stopper 26 is provided on the upper surface of the base 14. The other configurations are the same as those of the first embodiment, and detailed description will be omitted. The stopper 26 of the fourth embodiment is a member that moves forward and backward from the upper surface of the T-slot 20C toward the lower surface of the flanged member 30 at both ends of the T-slot 20C. The stopper 26 can be changed between a state in which it protrudes from the upper surface of the T-slot 20C and a state in which its tip is flush with the upper surface of the T-slot 20C by operating the lever of an operating member (not shown) provided on the base 14. In this type of child car seat, the seat 12 can be attached and detached in the same manner as in Example 1, but when attaching or detaching the seat 12, the stopper 26 is retracted using the operating member of the base 14. After the seat 12 is attached, by leaving the stopper protruding from the upper surface of the T-slot 20C, the seat 12 can be prevented from coming off the attachment or detachment position during sliding movement.

[0020] Example 5 FIG. 26 is a perspective view of a child car seat according to a fifth embodiment. FIG. 27 is a perspective view of the seat of the child car seat according to the fifth embodiment attached to a base. FIG. 28 is a front cross-sectional view of the seat of the child car seat according to the fifth embodiment attached to a base. FIG. 29 is a perspective view of the fixing position of the child car seat according to the fifth embodiment. FIG. 30 is a front cross-sectional view of the fixing position of the child car seat according to the fifth embodiment. FIG. 31 is a perspective view of the seat of the child car seat according to the fifth embodiment facing right. FIG. 32 is a perspective view of the seat of the child car seat according to the fifth embodiment facing rearward. FIG. 33 is a perspective view of the seat of the child car seat according to the fifth embodiment facing left. In the child car seat shown in the fifth embodiment, the flanged member 30A has a circular shape with a flange. The flanged member 30A is provided with a lock pin 36 that moves back and forth from the bottom surface toward the top surface of the T-slot 20D, and the T-slot 20D has a pin hole 28 on the top surface into which the lock pin 36 fits. The lock pin 36 and pin hole 28 have smaller diameters than the convex portion 32A and the concave portion 22, so that the convex portion 32A does not fit into the pin hole 28. Other configurations are identical to those of the first embodiment, and detailed descriptions are omitted. The flanged member 30A of the fifth embodiment has a circular flange, and the flange fits into the flange of the T-slot 20D. Therefore, unlike the rectangular flanged member 30, the seat 12 can freely rotate around the axis of the convex portion 32A. Furthermore, the lock pin 36 protrudes from the underside of the flanged member 30A and is provided on the front side of the seat 12. By operating a lever of an operating member (not shown) provided on the seat 12, the lock pin 36 can be switched between a protruding state from the underside of the flanged member 30A and a retracted state where its tip is flush with the top surface of the flanged member 30A. Four pin holes 28 on the top surface of the T-slot 20D, into which the lock pins 36 fit, are provided in a cross pattern centered on the concave portion 22. The positions at which the lock pin 36 provided on the front side of the seat 12 fits into the pin holes provided in a cross shape on the top surface of the base 14 are positions at which the seat 12 faces the front, rear, right side, or left side. In this type of child car seat, the seat 12 can be attached and detached using the same operations as in Example 1, but because the flanged member 30A is circular, it is easier to align the seat 12 from the side of the T-slot of the base when attaching it compared to a rectangular member. The seat 12 can be fixed in any orientation (front, back, right side, left side) by operating the lever of the operating member (not shown) of the seat 12 to extend the lock pin 36 (see Figures 31, 32, and 33).

[0021] According to the present invention, the seat can be slid horizontally between the fixed position on the base and the attached or detached position. The seat can also be detached at the attached or detached position away from the fixed position, preventing excessive strain on the arms of an adult when loading or unloading a heavy infant or heavy seat. In this embodiment, a configuration has been described in which the flanged member 30 is arranged on the sheet 12 side and the T-slot 20 is arranged on the base 14 side, but this is not limited to this and a configuration in which the T-slot 20 is arranged on the sheet 12 side and the flanged member 30 is arranged on the base 14 side may also be used. Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above embodiments and various modifications can be made without departing from the spirit and scope of the present invention. Furthermore, the present invention is not limited to the combinations shown in the embodiments, but can be implemented in various combinations. [Explanation of symbols]
