Further, as shown in FIGS. 1 and 2, the seat 60 has a pair of guard support members 75 extending from each base 61 and a guard member 76 detachable between the pair of guard support members 75. Have. Each guard support 75 is somewhat rotatable about the base 61 about an axis extending in the width direction. Further, the seat 60 has a pair of hood support members 77 fixed to each side support portion 72. Although not shown, the hood bone is hung between the pair of hood support members 77, and the hood cloth is attached to the hood bone.

In FIG. 8, the seat plate 68, the guard material 76, the hood support material 77, and the like are not shown.

Next, a holding member 50 provided on the baby carriage main body 20 to hold the seat 60 will be described. As shown in FIG. 6, a pair of holding members 50 are provided at positions between the pair of first link members 21 in the width direction. The pair of holding members 50 are arranged apart from each other in the width direction. As shown in FIG. 1, the pair of holding members 50 holds the seat 60 at a position between the pair of first link members 21 in the width direction.

The holding member 50 has a support portion 53 that supports the supported portion 63 provided on the seat 60. The support portion 53 may be formed as a receiving hole that opens upward or an insertion portion that protrudes upward. Further, the supported portion 63 may be configured as a downwardly projecting insertion portion that can be inserted into the receiving hole of the supporting portion 53, or a receiving hole that opens downward so that the insertion portion of the supporting portion 53 can be inserted. In the illustrated example, the holding member 50 has a receiving hole formed in the support surface 52 facing upward as the support portion 53. The support surface 52 extends in the front-rear direction. In other words, a receiving hole as the support portion 53 is formed in the central portion of the support surface 52 that extends in the front-rear direction. The support surface 52 faces upward, and the receiving hole forming the support portion 53 opens upward.

On the other hand, in the seat 60, a pair of base portions 61 arranged apart from each other in the width direction have a supported portion 63. That is, a pair of holding members 50 are provided so as to correspond to each base 61 so as to be separated from each other in the width direction. The base 61 has a supported surface 62 that faces downward. The supported surface 62 extends in the front-rear direction corresponding to the support surface 52. The insertion portion forming the supported portion 63 projects downward from the central portion of the supported surface 62 in the front-rear direction.

According to the configuration of the support portion 53 and the supported portion 63, the seat 60 can be held by the front legs 30 via the holding member 50 by lowering the seat 60 onto the baby carriage main body 20 from above in the vertical direction. It will be possible. More specifically, by lowering the seat 60, the supported portion 63 projecting downward from each of the pair of bases 61 is inserted into the support portion 53 of the corresponding holding member 50. Then, when the supported surface 62 of the base 61 comes into contact with the support surface 52 of the holding member 50, the seat 60 is held on the baby carriage main body 20. Since the support portion 53 is engaged with the supported portion 63 while the seat 60 is held by the stroller main body 20, the horizontal movement of the seat 60 with respect to the stroller main body 20 is restricted.

Further, the pair of holding members 50 and the pair of base portions 61 are arranged apart from each other in the width direction. Therefore, in a state where the seat 60 is held by the stroller body 20, the seat 60 centered on the axis along the front-rear direction and the stroller body 20 are displaced due to relative rotation, and the seat centered on the axis along the vertical direction. The deviation due to the relative rotation of the 60 and the baby carriage body 20 can be effectively regulated. In addition, as shown in FIGS. 6 and 8, the support surface 52 extends to the front and back of the support portion 53, and the supported surface 62 extends to the front and back of the supported portion 63. Therefore, in a state where the seat 60 is held by the baby carriage main body 20, the deviation due to the relative rotation of the seat 60 and the baby carriage main body 20 about the axis along the width direction can be effectively regulated. From the above, the seat 60 provided in the baby carriage main body 20 can stably hold the seat 60.

In the illustrated example, the baby carriage main body 20 has a link structure for enabling the folding operation. These link structures include a pair of configurations that are symmetrical about the central plane in the width direction, separated in the width direction. The pair of holding members 50 are arranged between the pair of configurations, and the seat 60 is held between the pair of configurations. Specifically, the seat 60 is held between the pair of first link members 21, between the pair of front legs 30, between the pair of rear legs 35, and between the pair of handle extension portions 42. Such an arrangement of the seats 60 makes it possible to avoid interference with the components of the baby carriage body 20. That is, the holding member 50 can hold the seat 60 so that the seat 60 is separated from the baby carriage main body 20. Therefore, as shown in FIG. 9, the orientation of the seat 60 held by the baby carriage main body 20 can be changed via the holding member 50. As a result, simply by changing the orientation of the seat 60, the infant shown in FIG. 9 (a) faces the front in the traveling direction of the baby carriage 10, and the infant shown in FIG. 9 (b) is the baby carriage 10. It is possible to switch between a face-to-face state facing the operator (guardian). Further, such an arrangement of the seats 60 can also make it possible to avoid interference between the baby carriage main body 20 and the seats 60 during the folding operation. Therefore, as shown in FIG. 3, the baby carriage main body 20 can be folded while holding the seat 60. In the illustrated baby carriage 10, the baby carriage 10 can be folded while the seat 60 is held by the baby carriage main body 20 in both the face-to-face state and the rear state.

Further, as shown in FIG. 8, the seat 60 has protrusions 64 urged inward in the width direction from each supported portion 63. Further, as shown in FIG. 6, in the holding member 50, a protrusion receiving 54 for receiving the protrusion 64 is formed on the inner wall portion in the width direction of the wall portion forming the support portion (receiving hole) 53. Since the lower side surface of the protrusion 64 is inclined, the protrusion 64 is automatically buried inside the supported portion 63 when the supported portion 63 is inserted into the supported portion 53. Then, when the protrusion 64 reaches a position facing the protrusion receiver 54, the protrusion 64 is fitted into the protrusion receiver 54 by an urging force from an urging means (not shown). That is, by inserting the supported portion 63 into the supporting portion 53, the seat 60 is fixed to the holding member 50.

As shown in FIG. 6, the holding member 50 has a protrusion releasing means 55 at a position facing the protrusion receiving 54. The protrusion releasing means 55 projects inward in the width direction from the holding member 50. By pushing the protrusion releasing means 55 outward in the width direction, the protrusion 64 fitted in the protrusion receiver 54 can be pushed out from the protrusion receiver 54. That is, when the seat 60 is removed from the baby carriage main body 20, by operating the protrusion releasing means 55, the fixing by the fixing means configured on the protrusion 64 and the protrusion receiving 54 can be released.

Next, the attachment structure and attachment position of the holding member 50 to the baby carriage main body 20 will be described.

In the present embodiment, as shown in FIG. 7, each holding member 50 is connected to a plurality of connection positions JPX and JPY separated from each other in the baby carriage main body 20. As a result, in the illustrated example, each holding member 50 is fixed to the stroller body 20 and is stably held by the stroller body 20. Further, the support portion 53 of the holding member 50 is located above one connection position JPX of the baby carriage main body 20. Therefore, the weight of the seat 60 held by the holding member 50 can be stably and efficiently supported by the baby carriage main body 20. Thereby, the rattling of the holding member 50 with respect to the baby carriage main body 20 can be effectively reduced. Further, since it is not necessary to increase the size of the holding member 50 or to provide a large number of holding members 50, the design of the baby carriage 10 can be improved.

In the illustrated example, each holding member 50 is first connected to the handle extending portion 42 at AR1 on the rotation axis of the second link member 22 and the handle extending portion 42. As a specific configuration, as shown in FIGS. 6 and 7, each holding member 50 is connected to a spindle member 25 that rotatably connects the second link member 22 and the handle extending portion 42. That is, in the illustrated example, the first connection position JPX of the holding member 50 with respect to the baby carriage main body 20 is the spindle member 25. The spindle member 25 penetrates the holding member 50. The spindle member 25 further penetrates the second link member 22 and the third link member 23. Therefore, the holding member 50 is connected not only to the handle extending portion 42 of the handle 40 but also to the second link member 22 and further to the third link member 23 via the spindle member 25.

Further, each holding member 50 is connected to the reinforcing connecting member 45 of the handle 40. The reinforcing connecting member 45 is connected to the handle extending portion 42 as a part of the handle 40. That is, in the illustrated example, the second connection position JPY of the holding member 50 with respect to the baby carriage main body 20 is the reinforcing connecting member 45. As shown in FIG. 7, the holding member 50 has a through hole 56 through which the reinforcing connecting member 45 passes. The cross-sectional shape of the reinforcing connecting member 45 is somewhat flattened from the circular shape. The through holes 56 of the holding member 50 are also somewhat flattened. Therefore, the reinforcing connecting member 45 penetrates the through hole 56 of the holding member 50, so that the relative rotation of the holding member 50 with respect to the baby carriage main body 20 along the axis along the width direction is restricted.

In such a baby carriage 10, the first connection position JPX of the holding member 50 to the baby carriage main body 20 is a spindle member 25 and is connected to a lower portion of the holding member 50. Then, as shown in FIG. 7, the support portion 53 of the holding member 50 is arranged at a position displaced upward along the vertical direction from the spindle member 25. Therefore, the weight of the seat 60 held by the holding member 50 can be efficiently supported by the baby carriage main body 20 without increasing the size of the holding member 50 or providing a large number of holding members 50.

Further, the second connection position JPY of the holding member 50 to the baby carriage main body 20 is a reinforcing connecting member 45 and is connected to the rear portion of the holding member 50. Therefore, as shown in FIG. 7, the holding member 50 faces the reinforcing connecting member 45 from the front along the front-rear direction. The support portion 53 of the holding member 50 is arranged at a position displaced forward along the front-rear direction from the reinforcing connecting member 45. Therefore, the baby carriage main body 20 can efficiently and stably receive the inertial force from the seat 60 when moving forward through the holding member 50. As a result, it is possible to more effectively suppress the occurrence of rattling of the holding member 50 with respect to the baby carriage body 20.

Further, when the two connection positions JPX and JPY of the baby carriage main body 20 are close to each other, the holding member 50 tends to rattle with respect to the baby carriage main body 20. On the other hand, if the insertion length IL of the support portion 53 of the holding member 50 and the supported portion 63 of the seat 60 along the vertical direction is long, the rattling of the seat 60 with respect to the holding member 50 is effectively suppressed. be able to. On the other hand, if the insertion length IL is long, a large force is applied to the holding member 50, and the holding member 50 tends to rattle with respect to the baby carriage body 20. Regarding this point, as shown in FIG. 7, the separation distance D between the two connection positions JPY and JPY is larger than the vertical insertion length IL of the support portion 53 of the holding member 50 and the supported portion 63 of the seat 60. It's getting longer. This also makes it possible to more effectively suppress the occurrence of rattling of the holding member 50 with respect to the baby carriage body 20.

In addition, in order to efficiently support the force applied to the holding member 50 by the stroller body 20, the distances D1 and D2 from the support portion 53 of the holding member 50 to the stroller body 20 to the connection positions JPY and JPY are shortened. It is effective to be there. The distance from the support portion 53 of the holding member 50 to any one of the connection positions JPX and JPY, and in particular the shortest distance between the support portion 53 of the holding member 50 and any one of the connection positions, is the support portion 53 and the supported portion 53. It is preferable that the insertion length of the portion 63 in the vertical direction is shorter than the IL. In the illustrated example, the shortest distance from the support portion 53 of the holding member 50 to the arbitrary connection positions JPX and JPY is shorter than the vertical insertion length IL of the support portion 53 and the supported portion 63. ing. That is, as shown in FIG. 7, the shortest distance D1 between the support portion 53 and the first connection position JPX is shorter than the vertical insertion length IL of the support portion 53 and the supported portion 63, and The shortest distance D1 between the support portion 53 and the second connection position JPY is shorter than the vertical insertion length IL of the support portion 53 and the supported portion 63.

In particular, in the illustrated example, the distance D1 along the vertical direction from the support portion 53 to the first connection position JPX located below the support portion 53 is the vertical insertion of the support portion 53 and the supported portion 63. It is shorter than the length IL. Therefore, the weight of the seat 60 held by the holding member 50 can be efficiently supported by the baby carriage main body 20 at the first connection position JPX. Further, the distance D2 along the front-rear direction from the support portion 53 to the second connection position JPY located behind the support portion 53 is larger than the vertical insertion length IL of the support portion 53 and the supported portion 63. It's getting shorter. Therefore, the baby carriage main body 20 can efficiently and stably receive the inertial force from the seat 60 at the time of forward movement at the second connection position JPY through the holding member 50.

As a result of the above mounting structure, the support portion 53 of the holding member 50 is located in the region surrounded by the first link member 21, the handle extending portion 42 of the handle 40, and the rear leg 35, as shown in FIG. .. That is, the support portion 53 of the holding member 50 is generally located at the center of the baby carriage main body 20. As a result, the seat 60 can be supported stably and efficiently.

By the way, as described above, the first connection position JPY of the holding member 50 to the baby carriage body 20 is the spindle member 25, and the second connection position JPY is the reinforcing connecting member 45. Therefore, the holding member 50 is connected to the second link member 22, the third link member 23, and the handle extending portion 42 of the handle 40 via the spindle member 25. Further, the holding member 50 is connected to the handle extending portion 42 of the handle 40 via the reinforcing connecting member 45. That is, the holding members 50 are connected to different positions on the handle extending portion 42 of the handle 40 via different paths. Therefore, the holding member 50 is fixed to the handle 40. Here, "fixed to the handle 40" means not only directly connected to the handle, but also indirectly connected to the handle via other members and relative to the handle 40. Including keeping constant.

As described above, in the unfolded state shown in FIG. 2, the handle 40 is arranged at a high position. On the other hand, in the folded state shown in FIG. 3, the handle 40 is arranged at a low position. By fixing the holding member 50 to such a handle 40, the seat 60 is arranged at a high position in the vertical direction in the deployed state. By arranging the seat 60 at a high position, the infant on the seat 60 can effectively avoid the influence of heat and dust from the ground. Further, since the seat surface 65A of the seat 60 is high, it is possible to easily and stably carry out loading and unloading of infants. On the other hand, in the folded state, as shown in FIG. 3, the handle 40 is arranged at a low position. Along with the handle 40, the seat 60 is also arranged at a low position. Therefore, the folding dimension of the baby carriage 10 can be reduced.

Further, the orientation of the holding member 50 is also constant with respect to the handle 40. Therefore, the seat 60 held by the holding member 50 does not generate a large moment during the folding operation. On the other hand, the weight of the seat 60 pushes down the steering wheel 40. That is, the weight of the seat 60 assists the folding operation of lowering the handle 40. Therefore, the folding operation can be smoothly performed.

In the illustrated example, in the side view shown in FIG. 2, the seat surface 65A formed by the seat 60 is located above the connection position JP1 between the first link member 21 and the front leg 30. .. Similarly, in the side view shown in FIG. 2, the swing axis AS1 of the back portion 70 with respect to the seat portion 65 is located above the connection position JP2 between the first link member 21 and the rear leg 35. Further, in the side view shown in FIG. 2, the swing axis AS1 of the back portion 70 with respect to the seat portion 65 is located above the connection position JP4 between the handle 40 and the second link member 22. Further, in the side view shown in FIG. 2, the swing axis AS2 of the side frame member 73 with respect to the side support portion 72 is located above the first link member 21. Further, the swing axis AS2 of the side frame member 73 with respect to the side support portion 72 is located above the connection position JP1 between the first link member 21 and the front leg 30, and the first link member 21 and the rear leg 35 It is located above the connection position JP2 of the above, and further above the connection position JP3 of the first link member 21 and the handle 40. In the specific example illustrated in this way, since the seat 60 is held at a high position in the deployed state of the baby carriage 10, it is possible to easily carry out the loading and unloading of the baby, the reclining operation, the opening / closing operation of the hood, and the like. On the other hand, as described above, since the seat 60 is fixed to the handle 40, the folding dimension of the baby carriage 10 can be sufficiently miniaturized.

The baby carriage 10 having the above configuration runs when the operator (user, guardian) grips the handle connecting portion 43 of the handle 40 and pushes the handle 40. In the baby carriage 10, as shown in FIG. 9, the holding member 50 can hold the seat 60 by changing the orientation of the seat 60. That is, it is not necessary to swing the handle 40 when switching between the back surface state and the face-to-face state. Therefore, the handle 40 is less likely to interfere with other components of the stroller 10. Therefore, the reinforcing connecting member 45 for connecting the pair of handle extending portions 42, which has been considered impossible to install, can be installed on the handle main body 41.

In the illustrated example, the handle 40 has a pair of handle extensions in addition to a handle body 41 having a handle connecting portion 43 that connects the ends of the pair of handle extending portions 42 and the pair of handle extending portions 42. It further has a reinforcing connecting member 45 that connects the portion 42 at a position separated from the handle connecting portion 43. The rigidity of the handle 40 is improved by the handle connecting portion 43 effectively reinforcing the handle body 41. As a result, when a force is applied to the handle connecting portion 43 which is the upper end portion of the handle 40, the deformation of the handle 40 can be effectively suppressed. As a result, the force applied to the handle 40 is effectively used for the running of the baby carriage 10. Further, the operator can sufficiently grasp the state of the traveling surface and the like through the steering wheel 40. From these things, the maneuverability of the baby carriage 10 can be remarkably improved.

In addition, in the illustrated baby carriage 10, the handle is extended at a position where the member connected between both ends of the reinforcing connecting member 45 in the width direction deviates from the connection position between the reinforcing connecting member 45 and the handle extending portion 42. It is connected to the unit 42. More specifically, the member connected between both ends of the reinforcing connecting member 45 in the width direction includes the holding member 50. As a result, the rigidity of the handle 40 can be further improved. In particular, the holding member 50 has a function of holding the seat 60, and therefore, the rigidity of the handle 40 can be efficiently improved without increasing the number of parts.

Further, this member connected between both ends of the reinforcing connecting member 45 in the width direction is connected to the handle extending portion 42 on the rotation axis AR1 of the second link member 22 and the handle extending portion 42. .. More specifically, the member connected between both ends of the reinforcing connecting member 45 in the width direction further includes the spindle member 25. In such a baby carriage 10, the rigidity of the handle can be further improved. In particular, the rigidity of the spindle member 25 can be improved, whereby the folding operation and the unfolding operation can be facilitated.

According to one embodiment described above, the baby carriage 10 has a foldable baby carriage main body 20 and a seat 60 held by the baby carriage main body by a holding member 50 provided on the baby carriage main body. The baby carriage body includes a first link member 21, a front leg 30 and a rear leg 35 rotatably connected to the first link member, a handle 40 rotatably connected to the first link member, and a front leg and a handle. It has a second link member 22 provided between them and rotatable with respect to the front leg and the handle. The holding member 50 is fixed to the handle. In such a baby carriage 10, when the baby carriage main body 20 is folded, the handle 40 and the front leg 30 are close to each other, and the handle 40 is lowered. As a result, the folding dimensions of the baby carriage 10 in the front-rear direction and the up-down direction can be reduced. Further, in the baby carriage 10, the holding member 50 that supports the seat 60 is fixed to the handle 40. Therefore, when the baby carriage body 20 is folded, the seat 60 is also lowered. Thereby, the folding size of the baby carriage 10 can be effectively reduced. In addition, the handle 40 has less change in orientation due to the folding operation as compared with the first link member 21 and the second link member 22. Therefore, the change in the orientation of the seat 60 at the time of folding is also suppressed, and the baby carriage 10 can be stably folded. On the contrary, the weight of the seat 60 can also induce the folding motion of the baby carriage 10 with the lowering of the handle 40. From the above, according to the present embodiment, the folding dimension of the baby carriage 10 can be sufficiently miniaturized. In addition, the folding operation of the baby carriage 10 can be performed smoothly and stably.

In one specific example described above, the holding member 50 holds the seat 60 so that the seat 60 is separated from the baby carriage main body 20. In such a baby carriage 10, if the seat 60 does not interfere with the components other than the handle 40 of the baby carriage main body 20, the baby carriage 10 can be folded without removing the seat 60 from the baby carriage main body 20.

In one specific example described above, the baby carriage body 20 can removably hold the seat 60, and can hold the seat 60 in a front-rear direction. That is, in the baby carriage 10, the baby is made to ride so as to face the operator (guardian of the baby, the user of the baby carriage) of the baby carriage 10 (face-to-face state), and the baby is placed facing forward in the moving direction of the baby carriage. Both can be boarded (rear state). Further, if the seat 60 does not interfere with the components other than the handle 40 of the stroller body 20, the stroller 10 can be folded with the seat 60 attached to the stroller body 20 without depending on the orientation of the seat 60. ..

In one specific example described above, the holding member 50 is connected to the handle 40 at two or more points. Thereby, the holding member 50 can be fixed to the handle 40 by a simple structure.

In one specific example described above, the handle 40 handles a handle body 41 having a handle connecting portion 43 connecting a pair of handle extending portions 42 and a pair of handle extending portions 42, and a pair of handle extending portions 42. It has a reinforcing connecting member 45 that is connected at a position separated from the connecting portion 43, and the holding member 50 is connected to the reinforcing connecting member 45. In such a baby carriage 10, the rigidity of the handle 40 is improved by the reinforcing connecting member 45. Then, by connecting the holding member 50 to the reinforcing connecting portion 45, the seat 60 can be stably held by the baby carriage main body 20.

In one specific example described above, the holding member 50 is connected to the handle extending portion 42 on the rotation axis AR1 of the second link member 22 and the handle extending portion 42. The positions of the rotation axis AR1 of the second link member 22 and the handle 40 are lowered during the folding operation of the baby carriage body 20. Along with this lowering, the second link member 22 and the handle 40 rotate about the rotation axis AR1. On the other hand, in the baby carriage 10, the weight of the seat 60 held by the holding member 50 is added on the rotation axis AR1 between the second link member 22 and the handle extending portion 42. Therefore, the weight of the seat 60 makes it possible to smoothly guide the folding operation of the baby carriage main body 20.

In one specific example described above, the holding member 50 is connected to the handle extending portion 42 via a spindle member 25 that rotatably connects the second link member 22 and the handle extending portion 42. The position of the main shaft member 25 is lowered during the folding operation of the baby carriage main body 20, and the second link member 22 and the handle 40 are relatively rotated with the lowering. Then, the weight of the seat 60 held by the holding member 50 is added to the spindle member 25, so that the folding operation of the baby carriage main body 20 can be smoothly guided.

In one specific example described above, the baby carriage body 20 is provided between each rear leg 35 and the handle 40, and has a pair of third link members 23 that are rotatable with respect to the corresponding rear leg 35 and the handle 40. Further, the third link member 23 is connected to the handle extending portion 42 and the second link member 22 and the rotatable AR1 by the spindle member 25. In such a baby carriage 10, the weight of the seat 60 held by the holding member 50 is added to the spindle member 25, so that when the rear leg 35 connected to the third link member 23 and the third link member 23 is folded. The movement will also be guided. Therefore, the folding operation of the baby carriage main body 20 can be guided more smoothly.

In one specific example described above, a pair of holding members 50 are provided between both ends of the reinforcing connecting member 45 so as to be separated from each other in the width direction. In the baby carriage 10, the seat 60 can be held by a pair of holding members 50 separated in the width direction. As a result, the baby carriage body 20 can hold the seat 60 more stably. It is also possible to hold the seats 60 inside both ends of the reinforcing connecting member 45. In this case, by preventing the seat 60 from interfering with the components of the stroller body 20, it is possible to fold the stroller 10 with the seat 60 attached to the stroller body 20.

In the above-mentioned specific example, in the side view of the baby carriage 10, the holding member 50 is located in the area surrounded by the first link member 21, the handle 40, and the rear leg 35. That is, the baby carriage body 20 can receive the weight of the seat 60 held by the holding member 50 in the area surrounded by the first link member 21, the handle 40, and the rear legs 35 in the side view. By receiving the seat 60 in the region where the baby carriage main body 20 has high rigidity in this way, the seat 60 can be stably held and the maneuverability of the baby carriage 10 can be improved.

In one specific example described above, in the side view of the baby carriage 10, the seat surface 65A formed by the seat 60 is located above the connection position JP1 between the first link member 21 and the front leg 30. Further, the seat 60 has a seat portion 65 and a back portion 70 that can swing with respect to the seat portion 65, and in the side view of the baby carriage 10, the swing axis AS1 of the back portion 70 with respect to the seat portion 65 is the first link. The connection position between the member 21 and the rear leg 35 is located above JP2. Further, the seat 60 has a seat portion 65 and a back portion 70 that can swing with respect to the seat portion 65, and in a side view of the baby carriage 10, the swing axis AS1 of the back portion 70 with respect to the seat 60 is a handle 40. It is located above the connection position JP4 with the second link member 22. By increasing the height of the seat 60 in this way, it is possible to improve the riding comfort of the baby carriage 10 and facilitate the loading and unloading of the baby in the seat 60.
