The frame 18 includes a pair of left and right side frames 28 each having a front leg frame member 24 and a rear leg frame member 26 integrally extending downward at the front and rear ends of a body frame member 22 extending in the front-rear direction. A bottom frame 30 is sandwiched between the lower ends of the front leg frame element 24 and the rear leg frame element 26.

The bottom frame 30 has a step 32 at the front end and a basket placing portion 36 on which a basket 34 is placed at the rear end, and the step 32 and the basket placing portion 36 are two guide pieces 38. It is configured by connecting with.

The stroller seat 20 is composed of a seat cushion 40 and a seat bag 42, and is supported on the frame 18 so as to be rotatable left and right (around the vertical line), and normally, the stroller is positioned so as to face the front of the stroller. Is fixed, but it can be fixed in other turning positions. Further, the seat bag 42 has a reclining mechanism that can tilt in the front-rear direction.

A front leg shaft 44 is spanned in the stroller width direction between the front leg frame members 24, and the upper ends of the front wheel legs 14 are axially supported by both ends of the front leg shaft that penetrates the front leg frame member 24. A front wheel 46 is rotatably supported at the lower end of the shaft 14. Similarly, a rear leg shaft 48 is laid between the rear leg frames 26 in the widthwise direction of the stroller, and the rear wheel legs 16 are provided at both ends of the rear leg shaft 48 penetrating the rear leg frame 26. Of the rear wheel leg 16 is rotatably supported on the lower end of the rear wheel leg 16.

By rotating the front leg shaft 44 around this axis, the front wheel leg 14 is interlocked between the deployed position shown in FIG. 1 (the position where the stroller 10 can travel) and the folded position shown in FIG. Can be rotated. Similarly, when the rear leg shaft 48 rotates about this axis, the rear wheel legs 16 are moved between the deployed position shown in FIG. 1 (the position where the stroller 10 can travel) and the folded position shown in FIG. , Can rotate in conjunction. In the folded position, both the front wheel legs 14 and the rear wheel legs 16 are substantially horizontal, and the lower surface of the bottom frame 30 can be grounded.

In the deployed position of the front wheel leg 14, the front wheel 46 is positioned forward of the stroller 10 with respect to the front leg shaft 44, and the ground load received by the front wheel 46 is applied to the front wheel leg 14 in the deployment direction (clockwise direction in FIG. 1, arrow A). Exerts a rotational biasing force. A stopper pin 52 projects inward in the widthwise direction of the stroller at an intermediate portion of the front wheel leg 14, and the stopper pin 52 abuts the lower surface of the step 32 of the bottom frame 30 at the unfolded position of the front wheel leg 14 to move the front wheel. The rotation of the leg 14 in the deploying direction is prevented.

The stopper pins 52 may be provided on the front wheel legs 14 of the left and right front wheel legs 14 respectively, or because the left and right front wheel legs 14 rotate together. It may be provided only on one of the front wheel legs 14.

A lock pin 54 is also provided at an intermediate portion of the front wheel leg 14, and the lock pin 54 is projected outward in the widthwise direction of the stroller. A sensor lever 56 is provided on the side surface of the step 32 corresponding to the lock pin 54. The sensor lever 56 extends in the front-rear direction of the stroller, and an intermediate portion of the sensor lever 56 is pivotally supported by a sensor lever shaft 58 whose axial direction is the vehicle width direction. The rear end of the sensor lever shaft 58 is bent upward to form a hook portion 60, and the front end is bent downward to form a sensor portion 62. The sensor lever 56 is rotatable about the sensor lever shaft 58 between a first position and a second position, and when the front wheel leg 14 is in the deployed position, the hook portion 60 causes the lock pin 54 to move in the first position. Engage (shown in FIG. 1) and the hook 60 disengages from the lock pin 54 in the second position (shown in FIG. 3). When the hook portion 60 engages with the lock pin 54, rotation of the front wheel leg 14 in the folding direction (counterclockwise direction in FIG. 1, indicated by arrow B) is blocked.

A torsion coil spring (not shown) is fitted to the sensor lever shaft 58, and the sensor coil 56 is always urged to rotate to the first position by the torsion coil spring. .

At the first position of the sensor lever 56, the sensor portion 62 projects downward from the lower surface height position of the step 32 (FIG. 1). As shown in FIG. 3, in order to mount the stroller 10 on the vehicle 64, the front wheels 46 are floated and the step 32 is placed on the vehicle body rocker portion 66 of the vehicle 64, and the sensor portion 62 is pressed by the vehicle body rocker portion 66. The sensor lever 56 rotates in the direction of arrow A against the torsion coil spring. As a result, the hook portion 60 is disengaged from the lock pin 54, and rotation of the front wheel leg 14 from the deployed position in the folding direction is permitted.

In the vehicle 64 in which the stroller 10 is mounted, as shown in FIG. 11, the passenger seat 68 includes a walk-in mechanism (not shown).

It may be provided only on one of the left and right front wheel legs 14 in terms of the structure for rotating.

Of the left and right rear leg frame members 26, a support plate 76 is attached to the right rear leg frame member 26 when viewed from the front of the stroller, as shown in FIGS. 7 and 8. The support plate 76 is provided orthogonally to the stroller width direction, and the support plate 76 is provided with the first lever 78 and the second lever 80 arranged in a substantially C-shape when viewed from the stroller width direction. A lever 82 is disposed between the first lever 78 and the second lever 80, and is pivotally supported by a first shaft 84, a second shaft 86, and a third shaft 88 having a stroller width direction as an axial direction. It is freely rotatable. Further, the rear leg shaft 48 passes through the support plate 76, and a cam plate 89 that rotates together with the rear leg shaft 48 is fitted to the rear leg shaft 48.

The first lever 78 is formed in a long plate shape, and the first shaft 84 penetrates at one end (upper end) thereof.

The second lever 80 is made of a back piece 90 and a pair of opposing pieces 92, and has an elongated U-shape when viewed from the longitudinal direction. One end (upper end) of the second lever 80 extends between the opposing pieces 92. An engaging pin 94 parallel to the second shaft 86 is stretched between the opposite pieces 92 at the other end (lower end) thereof. A torsion coil spring 96 is fitted to the second shaft 86, and according to the torsion coil spring 96, the second lever 80 is closed so that the second lever 80 and the first lever 78 are closed. In FIG. 7, it is urged to rotate clockwise or in the direction of arrow A.

The third shaft 82 penetrates the middle portion of the third lever 82, one end (upper end) of the third lever 82 enters the inside of the second lever 80 and extends toward the back piece 90, and the other end. The (lower end) extends toward the middle portion of the first lever 78. The third lever 82 is movable along with the third shaft 88 in the axial direction together with the support plate 76 in the direction of approaching / separating, and contacts the first lever 78 in the rotating direction of the third lever 82. A possible position and a position in which the third lever 82 cannot be brought into contact with the first lever 78 in the rotation direction of the third lever 82 are obtained. A compression coil spring 98 is fitted on the third shaft 88 between the third lever 82 and the mounting plate 76. According to the compression coil spring 98, the third lever 82 moves in the first direction in this rotation direction. It is constantly urged to a position where it can contact the lever 78 (a position away from the support plate 76). The shaft head 100 that penetrates the third lever 82 of the third shaft 88 has a spherical shape.

The cam plate 89 is formed in a fan shape, an engaging concave portion 102 corresponding to the engaging pin 94 is formed in the middle of the outer peripheral portion, and the outer peripheral portion is formed at the counterclockwise end portion in FIG. The wall thickness gradually changing portion 104 is formed so that the wall thickness gradually increases in the clockwise direction, and the wall thickness portion 106 continues between the wall thickness reducing piece portion 104 and the engaging recess 102. The shaft head 100 of the third shaft 88 is located on the rotation trajectory of the gradually changing wall thickness portion 104 and the wall thickness portion 106.

As shown in FIGS. 1 and 7, when the rear wheel leg 16 is in the deployed position (in FIG. 7, the rear wheel leg 16 is indicated by a chain line passing through the rear leg shaft 48 and the rear wheel 50). The rear wheel 50 is behind the rear leg shaft 48, and the ground load received by the rear wheel 50 is applied to the rear wheel leg 16 in the folding direction (counterclockwise direction in FIG. 7, arrow B). Exert. In the extended position of the rear wheel leg 16, the engagement pin 94 of the second lever 80 engages with the engagement recess 102 of the cam plate 89, and in this engaged state, the folding direction rotation that extends to the rear wheel leg 16 is performed. The power acts so as not to disengage the engagement pin 94 from the engagement recess 102, so that the cam plate 89 cannot rotate in the folding direction of the rear wheel leg 16 and rotates in the folding direction of the rear wheel leg 16. Movement is blocked.

At this time, the upper end of the third lever 82 is in contact with the back piece 90 of the second lever 80 and the lower end is in contact with the first lever 78, and the torsion coil spring 96 causes the first lever 78 to move. , It is biased to a position tilted slightly forward.

An operating lever 108 bent in an L shape is provided on the bottom frame 30 in the vicinity of the stopper recess 74, and the actuating lever 108 has an intermediate portion of the bending which is the widthwise direction of the stroller. It is pivotally supported by an operating lever shaft 110, and one end of the operating lever 108 and the lower end of the first lever 78 are connected by a connecting rod 112. When the front wheel leg 14 rotates in the folding direction and the stopper pin 52 enters the stopper recess 74, the stopper pin 52 presses the other end of the operating lever 108. As a result of this pressing, the operating lever 108 rotates in the direction of arrow A from the position indicated by the solid line to the position indicated by the two-dot chain line, as shown in FIG. This rotation is transmitted to the first lever 78 via the connecting rod 112, and the first lever 78 moves from a position slightly inclined forward (position in FIG. 7) to a substantially vertical position as shown in FIG. , Rotate in the direction of arrow B. By this rotation, the intermediate portion of the first lever 78 presses the lower end of the third lever 82, and the third lever 82 rotates in the arrow B direction. By this rotation, the upper end of the third lever 82 further presses the back piece 90 of the second lever 80, and the second lever 80 rotates in the direction of arrow B against the torsion coil spring 96. Then, the engagement pin 94 separates from the engagement recess 102. This detachment allows the cam plate 89 to rotate in the direction of arrow B (the folding direction of the rear wheel leg 16).

When the front wheel legs 14 are folded, as shown in FIG. 5, most of the stroller 10 enters the vehicle 64, the stroller 10 is horizontal, and the rear wheels 50 are in a floating state. When the bottom frame 30 is further slid on the rocker 66 after the front wheel leg 14 is rotated to the folding position, the intermediate portion of the rear wheel leg 16 comes into contact with the vehicle body rocker portion 66 (FIG. 5). When pushed, the rear wheel leg 16 rotates in the folding direction, and the cam plate 89 also rotates in the same direction as the rear wheel leg 16. As shown in FIG. 10, as the cam plate 89 rotates, the gradually changing portion 104 of the cam plate 89 slides on the shaft head 100 of the third shaft 88, and the thick portion 106 of the cam plate 89 moves. When contacting the shaft head 100, the shaft head 100 of the third shaft 88 is pressed and moved in the direction of approaching the support plate 76, and the third lever 82 moves in this rotation direction to the first lever 78. When it reaches a position where it cannot come into contact with the first lever 78, it is released from the first lever 78. By this separation, the second lever 80 is rotated by the torsion coil spring 96 in the direction of arrow A, and the engagement pin 94 is moved from the engagement recess 102 of the cam plate 89 to the outer circumference in the clockwise direction in FIG. Press on the end side. Thereafter, as the rear wheel leg 16 rotates in the folding direction, the thick portion 106 slides on the shaft head 100, and the cam plate 89 makes sliding contact with the engaging pin 94, so that the cam plate 89 moves. As the rear wheel legs 16 continue to rotate, the rear wheels 50 reach the folding position with the rear wheels 50 resting on the vehicle body rocker portion 66 (FIGS. 6 and 10).

At the folded position of the rear wheel leg 16, as shown in FIG. 10, the cam plate 89 is in a neutral state in which it is not subjected to the rotational biasing force in either the arrow A direction or the arrow B direction.

As described above, the stroller 10 allows the rear wheel legs 16 to be folded when the front wheel legs 14 are in the folding position. The stroller 10 reaches the vehicle body floor 72 from the vehicle body rocker portion 66 with the front and rear wheel legs 14 and 16 folded together.

In order to redeploy the front and rear wheel legs 14 and 16, the bottom frame 30 is slid outward on the vehicle body rocker portion 66 in the vehicle width direction and the stroller 10 is pulled out of the vehicle 64. Good. That is, the bottom frame 30 is slid outward on the vehicle body rocker portion 66 in the vehicle width direction, and first, the rear wheel legs 16 are manually rotated in the developing direction. As a result, from the state shown in FIG. 10, the cam plate 89 rotates in the direction of arrow A, the engagement pin 94 of the second lever 80 engages with the engagement recess 102 of the cam plate 89, and the rear wheel leg 16 obtains the deployed position. At this time, as the cam plate 89 rotates in the direction of arrow A, the shaft head 100 of the third shaft 88 slides past the thick portion 106 and then the gradually changing portion 104. After this, when the front wheel leg 14 rotates from the folded position in the developing direction and the stopper pin 52 separates from the other end of the operating lever 108, the first lever 78 rotates in the direction of arrow A via the connecting rod 112. By this rotation, the third lever 82 is prevented from moving on the side surface of the first lever 78 in the direction of separation from the support plate 76, and then moved to the first direction in the direction of rotation of the third lever 82. It returns to a position where it can contact the lever 78 (returns to the state of FIG. 7). When the front wheel leg 14 rotates in the deploying direction when the sensor lever 56 is in the first position, the lock pin 54 comes into contact with the outer peripheral portion of the hook portion 60 of the sensor lever 56, but the sensor lever 56 has the hook portion 60. By being pressed and rotated in the direction of arrow A (first position), the lock pin 54 can be engaged with the inside of the hook portion 60, and the front wheel leg 14 obtains the deployed position.

As shown in FIG. 11, a storage plate 114 that is flush with the vehicle floor 72 is attached to a vehicle body floor 72 that follows the vehicle body rocker portion 66, and the storage plate 114 has a coupling plate that constitutes a coupling member. Two 116 are provided in a row along the vehicle width direction. As shown in FIGS. 12 to 14, each coupling plate 116 has a shape in which the plate body 118 and the branch piece 120 are orthogonal to each other when viewed from the vehicle width direction, and is connected to the storage plate 114 corresponding to each coupling plate 116. Each of them is located in the recessed storage recess 122. The two coupling plates 116 are axially supported by a common coupling plate shaft 124 having the vehicle width direction as the axial direction in the storage recess 122, and the entire coupling plate 116 is stored in the storage recess 122 and the plate body 118 is stored. The storage position (the position of FIG. 12) where the recess 122 is closed on the same plane as the storage plate 114, and the rising position where the plate body 118 rises vertically and the branch piece 120 closes the storage recess 122 (FIG. 13, 14), it is rotatable around the coupling plate shaft 124 in an interlocking manner. In the storage position, the branch piece 120 contacts the inner wall 126 of the storage recess 122 to prevent rotation in the storage direction, and in the standing position, the plate body 118 contacts the opening edge 128 of the storage recess 122 and rises. Directional rotation is blocked. A torsion coil spring (not shown) is fitted to the coupling plate shaft 124. According to the torsion coil spring, the coupling plate 116 is rotationally biased in the rising direction (direction of arrow D). It Normally, the coupling plate 116 is held in the retracted position by a stopper (not shown) against the rotational urging force in the direction of arrow B, but the operation knob 130 provided on the retractable plate 114 can be slid. Thereby disengages the stop and the coupling plate 116 attains the upright position.

In order to store the coupling plate 116 from the standing position, the coupling plate 116 may be manually pushed and rotated in the storage direction, and the stopper works at the storage position.

The rising direction of the coupling plate 116 is preferably from the vehicle rear side (arrow D direction). According to this, when the passenger seat 68 is unintentionally retracted and comes into contact with the plate body 118 at the rising position of the joint plate 116, the joint plate 116 is pushed by the passenger seat 68 and stored. Since it rotates in the direction, interference between the passenger seat 68 and the connecting plate 116 is prevented.

Corresponding to the coupling plate 116, a coupling groove 132 extending in the stroller front-rear direction is formed on the lower surface of the basket placing portion 36 of the bottom frame 30, as shown in FIGS. 15 and 16. The coupling groove 132 is provided in the lower surface of the bottom frame 30 and is continuous with the first recess 134 that is continuous between the coupling groove 132 and the guide piece 38, between the guide pieces 38, and between the guide pieces 38. The stroller is opened to the front via a guide portion 138 formed of a second recess 136 formed on the lower surface. The distance between the guide portions 138 in the stroller width direction gradually increases from the coupling groove 132 toward the front of the stroller.

As the bottom frame 30 slides inward in the vehicle width direction on the vehicle body floor 72, the joint plate 116 is guided by the guide portion 138 and is introduced into the joint groove 132 and engaged therewith. .

When the coupling plate 116 is engaged with the coupling groove 132, the stroller 10 is prevented from moving to the left and right.

As shown in FIG. 13, of the two coupling plates 116, the coupling plate 116 on the outer side in the vehicle width direction has a U-shaped configuration in which the plate body 118 opens outward in the vehicle width direction when viewed from the vehicle front-rear direction. A connecting pin 140 having an up-down direction as an axial direction is hung between the open ends, and the lower surface of the basket mounting portion 36 of the bottom frame 30 corresponds to the up-down direction in correspondence with the connecting pin 140. A locking plate 144 is provided that is axially supported by a locking plate shaft 142 whose axial direction is. As the coupling plate 116 relatively moves in the coupling groove 132 toward the rear of the bebeker, the coupling pin 140 presses the locking plate 144. By this pressing, the locking plate 144 rotates in the direction of arrow C around the locking plate shaft 142, and the coupling pin 140 is locked by the locking recess 146 formed in the locking plate 144. It

As a result, the bottom frame 30 and the vehicle body floor 72 are joined together. In the standing state of each coupling plate 116, a retaining groove 250 is formed on the surface of the plate body 118 of each coupling plate 116 on the vehicle rear side from the outer end to the inner end in the vehicle width direction. Accordingly, a retaining projection (not shown) is provided in the coupling groove 132 on the stroller 10 side corresponding to the retaining groove 250. As the coupling plate 116 moves in the coupling groove 132, the retaining projection is formed. The stroller 10 is retained in the vertical direction by being inserted and fitted into the retaining groove. The inside of the retaining groove 250 in the vehicle width direction is formed into a stop portion 252 with a uniform groove width, and the outside of the retaining groove 250 in the vehicle width direction gradually extends outward in the vehicle width direction. The guide groove 254 is formed so as to have a wide groove width, and the retaining protrusion on the stroller 10 side is guided by the guide portion 254 and moves toward the stopper portion 252, and at the stopper portion 252, the bottom is formed. A connection position between the frame 30 and the vehicle body floor 72 is obtained. Since the guide portion 254 is formed so that the groove width gradually widens outward in the vehicle width direction, the guide portion 254 extends upward and downward between the stopper portion 252 and the stopper protrusion on the stroller 10 side for fitting. Even if high dimensional accuracy is required, the stopper protrusion on the stroller 10 side can easily reach the stopper 252.

To release the locking of the locking plate 144 with the connecting pin 140, the corresponding connecting plate 144 may be rotated in the direction opposite to the arrow C direction by an operating means (not shown).

After the connection between the bottom frame 30 and the vehicle body floor 72, as shown in FIG. 17, the stroller seat 20 of the stroller 10 is swung in the direction of arrow E from the state shown by the chain double-dashed line. The bag 42 is placed back to back with the seat bag 148 of the passenger seat 68 (state shown by the solid line) so that the stroller seat 20 faces the rear of the vehicle, that is, the child sitting on the seat cushion 40 faces the rear of the vehicle. To be done.

Here, as shown in FIG. 18, an assist grip 150 is provided on the back surface of the seat bag 148 of the passenger seat 68, and the assist grip 150 extends along the back surface of the seat bag 148 in the vehicle width direction.

Then, in the coupling groove 132, the coupling plate 116 is locked by the locking plate 144.

Since the guide portion 138 is widened toward the front of the stroller, at the beginning of the sliding of the bottom frame 30 on the vehicle body floor 72, without paying excessive attention to the position and orientation of the stroller 10, the connecting plate 138 can be connected. 116 can be located in the guide portion 138, and as long as the joint plate 116 is located in the guide portion 138, it is not necessary to confirm the engagement position between the joint plate 116 and the joint groove 132, and the bottom frame 30 can be As the body plate 72 slides, the joint plate 116 is introduced into the joint groove 132.

As a result, when the stroller 10 is fixed to the vehicle body, an easy and quick fixing operation is performed.

After that, the stroller seat 20 is turned so that the stroller seat 20 faces toward the rear of the vehicle, and the connecting pin 166 is provided between the back surfaces of the seat bag 42 of the stroller seat 20 and the seat bag 148 of the vehicle seat 68. It is coupled by engagement with the coupling hole 165.

As a result, the stroller 10 is fixed to the vehicle body above and below the stroller 10 and is reliably fixed even if the center of gravity is high.

In order to secure the fixing more securely, it is preferable to fix the turning position of the stroller seat 20 when the connecting hole 165 is connected to the connecting pin 166.

If the seat bag 42 of the stroller seat 20 is tilted and the stroller seat 20 is swung so that the back surface of the seat bag 42 of the stroller seat 20 is brought into sliding contact with the back portion 152 of the assist grip 150, the coupling hole 165 is formed. Reaches the engagement position with the coupling pin 166.

This makes the fixing operation easy and quick. In addition, the connection between the back surfaces of the seat bag 42 of the stroller seat 20 and the seat bag 148 of the passenger seat 68 may be modified as described below.

That is, as shown in FIG. 22 and FIG. 23, the coupling pin 204 having the vertical direction as the axial direction is provided on the arm portion 202 in the vehicle width direction of the assist grip 200 of the seat bag 148 of the passenger seat 68. It is provided. On the other hand, on the back surface of the seat bag 42 of the stroller seat 20, an overhanging portion 205 extends in the vehicle width direction along the back surface, and a connecting pin is engaged with the inward end portion of the overhanging portion in the vehicle width direction. A coupling recess 206 that can be fitted is provided, and an open end of the coupling recess 206 is closed by a closing lid 209. When the top portion 41 on the back surface of the seat bag 42 of the stroller seat 20 is brought into sliding contact with the back portion 152 of the assist grip 200 and the stroller seat 20 is swung in the direction of arrow E, the closing lid 209 abuts against the connecting pin 204 and presses it. Then, it moves in the direction of arrow G so as to open the open end of the coupling recess 206, and the coupling pin 204 is engaged in the coupling recess 206. After being engaged, the closing lid 209 moves and returns in the direction opposite to the arrow G direction, closes the open end of the coupling concave portion 206, and closes the seat bag 42 of the stroller seat 20 and the seat bag 148 of the passenger seat 68.
