<<The outline of the stroller>>

1 to 32 show the overall configuration of the stroller 10 of the present embodiment. The illustrated stroller 10 has a stroller body 11 having a main body frame 15 and a piece support unit 40 supported by the main body frame 15, a cloth piece 150 attached to the piece support unit 40, and a baby carriage body 11 connected thereto. The handle 70 is mounted on the wheel holding unit 100 of the foot 20 and the rear leg 21 before the main body frame 15, and the basket portion 90 supported by the stroller body 11. The cloth sheet 150 may use a known member having cushioning properties so as to be detachable from the sheet supporting unit 40. On the piece of cloth 150, the infant can sit or sleep. Further, although not shown, another member such as a cover may be further provided to the stroller 10.

As shown in Fig. 7, the stroller 10 of the present embodiment can fold the forefoot 20, the rear leg 21, and the handle 70 close to each other. Most of the constituent elements of the stroller body 11 are pivotally connected to each other for folding. Further, the cloth sheet 150 is formed using a flexible cloth or the like, and is deformable in accordance with the folding operation of the stroller 10.

Further, in the present embodiment, the handle 70 is coupled to the stroller body 11 and is swingable relative to the stroller body 11. The handle 70 can be rocked at the first position (backward pushing position, rear position) shown in Figs. 1, 3, and 5, and at the second position shown in Figs. 2, 4, and 6 (opposite side pushing Between position, front position). Therefore, the following two possibilities are possible: the operator (protector) holds the handle 70 from the back side of the infant and manipulates the stroller 10 and walks the stroller 10 to face the infant in the forward direction, and operates The handle 70 is gripped and operated by the handle 70 from the position on the front side opposite to the infant, and the stroller 10 is moved to make the rear side of the stroller 10 forward in the forward direction.

a wheel mounted on at least one of the front leg 20 and the rear leg 21 The holding unit 100 is configured as a so-called caster having a rotating body 110 that holds the wheel 101 in a rotatable manner, and an axis parallel to the axis of rotation Ar of the wheel 101 and a non-parallel axis (also referred to as "the caster axis Ac"). The rotating body 110 is supported as a rotatable fixed body 105 at the center. Further, the stroller 10 is provided with a switching mechanism 88 that automatically switches the state in which the rotating body 110 of the wheel holding unit 100 is rotatable relative to the fixed body 105 and the non-rotatable state, corresponding to the position of the handle 70. In particular, in the present embodiment, the wheel holding unit 100 having the caster is provided in all of the front leg 20 and the rear leg 21, and the switching mechanism 88 corresponds to the position of the handle 70, so that the leg positioned on the front side in the progress direction is mounted. The rotating body 110 of the wheel holding unit 100 is rotatable with respect to the center of the caster axis Ac of the fixed body 105, and restricts the caster 110 of the wheel holding unit 100 mounted on the rear side of the running direction with respect to the caster of the fixed body 105. The rotation of the center of the axis Ac.

In the present specification, the terms "front", "back", "upper", and "lower" of the components of the stroller 10 are meant to mean that the stroller 10 is in an unfolded state. Infants and young children are based on "before", "after", "up" and "down". Therefore, the "front-rear direction" is a direction in which the lower left side and the upper right side of the paper surface of FIGS. 1 to 4 are connected, and corresponds to the left and right directions of the paper sheets connecting FIGS. 5 and 6. Further, as long as there is no special instruction, the "front" is the side toward which the infant is riding, and is the lower left side of the paper of Figs. 1 to 4, and the left side of the paper of Figs. 5 and 6 is the "front side". On the other hand, the "up-and-down direction" is a direction orthogonal to the front-rear direction and orthogonal to the surface (ground) on which the stroller 10 is placed. Therefore, when the surface on which the stroller 10 is placed is a horizontal plane, the so-called "up and down direction" means a vertical direction. Again The term "horizontal" and "width direction" mean a direction orthogonal to both the "front-rear direction" and the "up-and-down direction". Further, the "right" and the "left" respectively mean the "right" and "left" in the horizontal or width direction based on the infant of the baby carriage 10.

As shown in the figure, the stroller 10 as a whole is configured to be substantially symmetrical about a center plane in the width direction extending in the front-rear direction. Hereinafter, each constituent element of the stroller 10 of the present embodiment will be described with reference to the drawings.

In the illustrated example, the end faces 26b2, 26b3 of the boss receiving portion 76b are formed in parallel with the radial direction centering on the axial direction da of the shaft member 13. When the handle 70 is at the first position (rear position), one of the end faces 26b2 of the projection 26b is disposed at a position facing the one end surface 76b2 of the one of the projection receiving portions 75b, so that the handle disposed at the first position can be restricted. 70 and then shake to the rear. On the other hand, when the handle 70 is at the second position (front position), the other end portion 26b3 of the projection 26b is disposed at a position opposite to the other end portion 76b3 of the projection receiving portion 75b, so that the restriction can be restricted. The handle 70 of the second position is further swung forward.

The handle 70 has a rocking restricting member 73 that is slidable relative to the handle 70 along the longitudinal direction of the handle main portion 72a of the handle body 71. The rocking restricting member 73 is engageable with a handle fixing pin 37 (see FIGS. 5 and 6) provided in the stroller body 11. When the handle fixing pin 37 is engaged with the swing restricting member 73, the handle 70 is locked to the second position (opposing surface pushing position) or the first position (back pushing position).

Next, referring mainly to FIGS. 22 to 27, the wheel holding unit 100 will be described. As described above, the wheel holding unit 100 mounted to the front leg 20 and the rear leg 21 is constructed as a so-called caster having the rotating body 110 that holds the wheel 101 in a rotatable manner and is centered on the caster axis Ac and will rotate. The body 110 is supported as a rotatable fixed body 105. Moreover, the stroller 10 is provided with: The switching mechanism 88 in a state in which the rotating body 110 of the wheel holding unit 100 is rotatable relative to the fixed body 105 and in a non-rotatable state can be automatically switched according to the position of the handle 70. The switching mechanism 88 will be described later, and will be described in detail with respect to the wheel holding unit 100.

The pair of forefoot 20 can be mounted with the wheel holding unit 100 configured to be the same or bilaterally symmetrical. Further, the pair of rear legs 21 may be mounted with the wheel holding unit 100 configured to be the same or bilaterally symmetrical. Further, the front leg 20 and the rear leg 21 can be mounted with the same configuration of the mounting portion of the foot only, and the wheel holding unit 100 is substantially identical in configuration. Therefore, an example of the wheel holding unit 100 configured as a caster will be described here.

As shown in FIGS. 22 and 23, the wheel holding unit 100 has a rotating body 110 that holds the wheel 101 through the axle 113 and a fixed body 105 that supports the rotating body 110 so as to be rotatable. The fixed body 105 is fixed to the corresponding front foot 20 or rear foot 21 . The rotation axis Ar of the wheel 101 coincides with the axial direction of the axle 113 and extends in the horizontal direction. In the present embodiment, the fixed body 105 supports the support shaft member 108, and the rotating body 110 is supported by the support shaft member 108 suspended from the fixed body 105, and is centered on the axial direction of the support shaft member 108 with respect to the fixed body 105. Rotatable.

As shown in FIGS. 22 and 23, the rotating body 110 has a wheel holder 120 that supports the wheel 101, a support block 115 that supports the wheel holder 120, and a support block 115. The first elastic structure 125 and the second elastic structure 127 between the wheel holders 120. The wheel holder 120 holds the axle 113 and holds the wheel 101 on both sides of the axle 113. In FIG. 23, the illustration of the wheel is omitted, and in FIG. 22, the one side is omitted. An illustration of the wheel. In the present embodiment, by rotating the shaft member 111, the wheel holder 120 is attached to the support block 115, and is pivotable about the axial direction sc2 of the rocking shaft member 111 with respect to the support block 115. Moreover, in the example shown in FIG. 22 and FIG. 23, the rotating body 110 further has the brake member 129 attached to the wheel holder 120 so that it can rock. The brake member 129 has a brake protrusion 129a that protrudes in a direction parallel to the rotation axis Ar. By the brake member 129 being rocked with respect to the wheel holder 120, the brake protrusion 129a can be engaged with the wheel 101, and in this state, the rotation of the wheel 101 centered on the rotation axis Ar can be restricted.

The first elastic structural body 125 and the second elastic structural body 127 are deformed by the operation of the support block 115 of the wheel holder 120. In other words, the first elastic structural body 125 and the second elastic structural body 127 are deformed to absorb the operation of the support block 115 of the wheel holder 120, thereby exhibiting a shock absorbing function. Here, the term "elastic structure" means a structure which has a property of being deformed when an external force is received and which is at least partially restored to its original shape when the external force is removed, and therefore, is not limited to rubber or resin. A block of a single elastic material, a spring or a bag of a sealing gas as described later, and a structure exhibiting the above properties may be included in the elastic structure. In the wheel holding unit 100 including the two elastic structures 125 and 127, it is preferable to satisfy at least one of the following conditions a and b from the viewpoint of exhibiting an excellent suspension function. The following condition a and condition b may be between the first elastic structural body 125 and the second elastic structural body 127, and the first elastic structural body 125 and the second structural body may be different in material, structure, arrangement, deformability, and the like. The elastic structure 127 is thereby realized.

Condition a:

When the operation of the support block 115 with respect to the wheel holder 120 is started, first, only the first elastic structure body 125 is pressed and deformed between the wheel holder 120 and the support block 115, and further progresses to When the wheel holder 120 is operated relative to the support block 115, the second elastic structure 127 is pressurized between the wheel holder 120 and the support block 115 in addition to the first elastic structure 125. And deformation.

Condition b:

When only the first elastic structure 125 is disposed between the wheel holder 120 and the support block 115, the first elastic structure 125 is deformed and the wheel holder 120 is operated only by a predetermined amount with respect to the support block 115. When the second elastic structure 127 is disposed between the wheel holder 120 and the support block 115, the strength of the second elastic structure 127 is deformed and the wheel holder 120 is opposed to the support block 115. The amount of force required to move a predetermined amount is different.

In the condition a, when the wheel holder 120 is opposed to the support block 115, only the first elastic structure 125 is deformed in the initial stage of the relative operation, and only the first elastic structure 125 opposes the wheel holder 120 and the support block 115. Relative action. On the other hand, when the relative movement of the wheel holder 120 and the support block 115 is performed, the second elastic structure 127 starts to deform, and the second elastic structure 127 opposes the relative relationship between the wheel holder 120 and the support block 115. action. For example, in the initial stage of the relative operation of the wheel holder 120 and the support block 115, the second elastic structure 127 is non-contact with at least one of the wheel holder 120 and the support block 115, and the wheel holder 120 and the support are provided. When the relative movement of the block 115 is performed, the second elastic structure 127 can be in contact with both the wheel holder 120 and the support block 115. When the second elastic structure 127 opposes the relative movement of the wheel holder 120 and the support block 115, the first elastic structure 125 continues to be deformed in accordance with the operation of the wheel holder 120 and the support block 115, and the second elastic structure The body 127 may cooperate with the first elastic structure 125 against the relative movement of the wheel holder 120 and the support block 115, or the first elastic structure 125 may not be opposed to the wheel holder 120 and the support block 115. Relative action.

In the condition b, the resistance against the relative movement of the first elastic structure 125 and the relative movement of the wheel holder 120 and the support block 115 are set when the wheel holder 120 and the support block 115 are operated only by a predetermined amount. The resistance of the second elastic structure 127 against the relative action may be different.

Next, the configuration of the elastic structures 125 and 127 of the present embodiment shown in the drawing and the configuration of the rotating body 110 associated with the support of the elastic structures 125 and 127 will be described. In the present embodiment, the first elastic structure 125 is formed of an elastic body 126 such as rubber. The illustrated elastomer 126 has a receiving portion 126a formed as a recess. The wheel holder 120 has a support protrusion 121a that is fitted into the receiving portion 126a. The first elastic structure 125 formed of the elastic body 126 can be held by the wheel holder 120 by the engagement of the support protrusion 121a and the receiving portion 126a. The elastic body 126 is formed in a substantially cylindrical shape, and its longitudinal direction is disposed such that it extends between the wheel holder 120 and the support block 115. When the wheel holder 120 is rocked relative to the support block 115, the elastic body 126 is compressed along its longitudinal direction. Therefore, for the car The resistance of the first elastic structure 125 that the wheel holder 120 and the support block 115 are relatively oscillated is not substantially fixed in accordance with the relative rocking of the wheel holder 120 and the support block 115.

Next, the configuration of the second elastic structural body 127 and the rotating body 110 that supports the second elastic structural body 127 will be described. As shown in FIGS. 22 and 23, the support block 115 of the rotating body 110 has a plate-shaped support plate portion 116 that extends in the vertical direction. On the other hand, the wheel holder 120 of the rotating body 110 has a holder base 121 pivotally connected to the support block 115 and an upper extension portion 122 extending upward from the rear side of the holder base 121. As shown in FIG. 23, the upper extension portion 122 is disposed at a position facing the support plate portion 116 of the support block 115. On the other hand, the axle 113 for holding the wheel 101 is held in the vicinity of the joint between the retainer base 121 and the upper extension portion 122 of the wheel retainer 120. Further, the above-described brake member 129 is pivotally connected to the upper extension portion 122.

In the present embodiment, the second elastic structure 127 is formed as a bag for sealing gas. The material to be a bag may be composed of rubber or resin having stretchability. In the illustrated example, the second elastic structural body 127 is formed as a resin bag 128 made of a sealing gas. The resin bag 128 is transparent or translucent. The resin bag 128 is supported by a support plate portion 116 of the support block 115 through a fastener (not shown). As shown in FIG. 24, the resin bag 128 is roughly formed in a cubic shape, and a concave portion 128a, a step portion 128b, and a fastener receiving portion 128c are formed.

The recessed portion 128a is formed on a surface on the side opposite to the upper surface of the wheel holder 120. The concave portion 128a extends linearly in a direction orthogonal to the rocking axis sc2 of the support block 115 with respect to the wheel holder 120. On the upper extension portion 122, a convex portion 123 is formed at a position facing the concave portion 128a. The convex portion 123 extends linearly in a direction orthogonal to the rocking axis sc2 of the support block 115 with respect to the wheel holder 120, and is in contact with the concave portion 128a when the wheel holder 120 is moved toward the support block 115.

The step portion 128b is provided below the surface on the side opposite to the support plate portion 116. The step portion 128b extends in a straight line in a direction parallel to the rocking axis sc2. Further, the support plate portion 116 is formed with a segment portion 117 at a position facing the step portion 128b. On the other hand, the fastener receiving portion 128c forms a space in which a fastener (not shown) for fixing the resin bag 128 to the support plate portion 116 is built. The space in the fastener receiving portion 128c forms a step for using a fastener head constituted by a screw or the like.

Next, the operation and effect of the wheel holding unit 100 of the present embodiment configured as described above will be described.

First, the wheel holding unit 100 of the present embodiment is provided with a first elastic structure that is deformed by the relative movement of the support block 115 of the wheel holder 120 between the support block 115 and the wheel holder 120 that are relatively movable. The body 125 and the second elastic structure 127. Preferably, the first elastic structure 125 and the second elastic structure 127 are in the above condition a, that is, when the operation of the wheel holder 120 with respect to the support block 115 is started, first, only the first elastic structure 125 is on the wheel. When the holder 120 and the support block 115 are pressed and deformed, and further progress to the operation of the wheel holder 120 with respect to the support block 115, the second elastic structure is included in addition to the first elastic structure 125. 127 is also pressurized and deformed between the wheel holder 120 and the support block 115. In the above stroller 10, when the weight of the stroller 10 is small, for example, boarding When the infant of the baby carriage is of a low age and the luggage is not placed in the basket 90, the first elastic structure 127 can effectively absorb the vibration or the rush during walking, and can exhibit an excellent suspension function. On the other hand, when the weight of the stroller 10 is large, for example, the infant who is riding the stroller 10 has a high age and the heavier baggage is placed in the basket 90, the first elastic structure 125 is utilized. The second elastic structural body 127 is different from the first elastic structural body 127 and the second elastic structural body 127, and can stably support the load and effectively absorb the vibration or the rush during walking, thereby exhibiting excellent performance. Shock absorber function. That is, the stroller 10 can be provided with excellent riding comfort without the weight of the stroller 10.

In addition, it is preferable that the first elastic structure 125 and the second elastic structure 127 have the condition b, that is, when only the first elastic structure 125 is disposed between the wheel holder 120 and the support block 115, the first elastic structure is used. When the body 125 is deformed and the force required for the wheel holder 120 to move only a predetermined amount with respect to the support block 115 is different from when only the second elastic structure 127 is disposed between the wheel holder 120 and the support block 115, The second elastic structure 127 is deformed and the magnitude of the force required to move the wheel holder 120 to the support block 115 by the same amount is different. That is, it is preferable that the resistance of the first elastic structure 125 that acts on the relative movement of the wheel holder 120 and the support block 115 and the resistance of the second elastic structure 127 that opposes the relative movement of the wheel holder 120 and the support block 115 are preferable. It is different. In the stroller 10, the first elastic structure 125 and the second one are appropriately designed between the first elastic structural body 125 and the second elastic structural body 127 in terms of material, structure, arrangement, deformability, and the like. The elastic structure 127, whereby the wheel holding unit can be used with a high degree of design freedom 100 gives the desired suspension function.

Further, the first elastic structure 125 and the second elastic structure 127 may satisfy both of the above conditions a and b. As an example, the resistance of the first elastic structure 125 that opposes the relative movement of the wheel holder 120 and the support block 115 is higher than that of the second elastic structure 127 that acts on the wheel holder 120 and the support block 115. When the weight of the stroller 10 is small, the first elastic structure 125 can stably support the load, and the first elastic structure 125 can effectively absorb the vibration or the rush during walking. Further, when the weight of the stroller 10 is large, the first elastic structure 125 can be used, or the first elastic structure 125 and the second elastic structure 127 can be used to more stably support the load and be effective. The ground absorbs vibration or rushing while walking. Therefore, the influence of the weight of the stroller 10 can be very effectively eliminated, and the stroller 10 can be given excellent ride comfort.

Further, in the above embodiment, the second elastic structure 127 is configured as a bag 128 for sealing a gas. The second elastic structure 127 can also appropriately correct the resistance of the second elastic structure 127 by adjusting the shape of the bag 128 or the filling amount of the gas, and in particular, the resistance change due to the change. Thereby, with the high degree of design freedom, the wheel holding unit can be given a desired suspension function.

Further, in the above-described embodiment, the pocket 128 which is the second elastic structural body 127 is formed with a concave portion 128a extending in a straight line shape. Moreover, one of the wheel holder 120 and the support block 115 will support the pocket 128 such that the recess 128a and the wheel holder 120 are orthogonal to the rocking axis sc2 of the support block 115. And extending, the other of the wheel holder 120 and the support block 115 has a convex portion 123 that will be located in the recess 128a when the wheel holder 120 and the support block 115 are opposed to each other. Since the second elastic structural body 127 is a bag 128 for sealing gas, it can be deformed in various directions. However, the second elastic structural body 127 which is deformable by the engagement of the concave portion 128a and the convex portion 123 is supported by the wheel holder 120 and the support. The other side of the block 115 maintains a predetermined positional relationship and the bag 128 undergoes a predetermined deformation. This ensures the desired shock absorption effect. Further, before the start of the operation of the wheel holder 120 with respect to the support block 115, even the deformable second elastic structure 127 and the other of the wheel holder 120 and the support block 115 are non-contact and deformable second elastic The structure 127 is not directly connected to the other of the wheel holder and the support block, and the second elastic structure 127 and the wheel holder 120 can be deformed by the engagement of the concave portion 128a and the convex portion 123. Another convenience of the support block 115 maintains a predetermined positional relationship, and the desired suspension effect can be stably ensured.

Further, in the above-described embodiment, by the engagement of the step portion 128b and the segment portion 117, the offset of the bag 128 on the support plate portion 116 of the support block 115 can be restricted, and the undesired direction can be suppressed. The deformation of the resin bag 128. Thereby, the second elastic structure 127 formed of the bag 128 can exhibit the desired shock absorbing effect. Further, in the above-described embodiment, the buckle receiving portion 128c having the step (hub) portion is formed in the bag 128 which is the second elastic structural body 127. With the fastener receiving portion 128c, the bag 128 can maintain a direction that is not easily deformed, whereby when the wheel holder 120 and the supporting block 115 are opposed to each other, the deformation of the bag 128 is substantially fixed, and the desired predetermined avoidance is exhibited. Shock function.

Further, the second elastic structural body 127 serves as a bag 128 for sealing gas. In the case of the configuration, when the wheel holder 120 operates on the support block 110, one of the wheel holder 120 and the support block 110 should be brought into contact with the bag 128 at the corner formed in the pocket 128. The second elastic structure 127 formed by the bag of the sealing gas 128 shows excellent resistance of the corners of the bag 128 to deformation, and on the other hand, after the corner starts to be more deformed, it can be softly deformed to sensitively absorb the wheel retention. The action of the device 120 relative to the support block 110. Therefore, the second elastic structure 127 can stably support the weight of the baby stroller 10 that is expected, and the second elastic structure 127 that supports the negative weight can exhibit a shock absorbing function that effectively absorbs the punch or vibration.

Further, the elastic structures 125 and 127 are not limited to the case of the bag 128 for sealing the gas, and the resistance of the elastic structures 125 and 127 to the relative movement of the wheel holder 120 and the support block 115 may be in the elastic structure 125, After the 127 deformation starts, it is not fixed and will change. In the above-described example, by appropriately setting the resistance of the elastic structures 125 and 127 to the relative movement of the wheel holder 120 and the supporting block 115, the stroller 10 can be excellent without the weight of the stroller 10. Comfortable.

Further, when at least one of the elastic structures 125 and 127 is exposed, the shock absorber function can be visually recognized, and the protector of the infant can be given a sense of security. In particular, the second elastic structure 127 formed of the bag of the sealing gas 128 can strongly conceive the shock absorbing function. In particular, when the bag 128 is transparent or translucent, the shock absorbing function can be more strongly thought of.

In the present embodiment, the wheel holding unit 100 is configured as a caster, and the rotating body 110 is rotatable with respect to the fixed body 105, but the present invention is not limited thereto. Even if the rotating body 110 and the fixed body 105 are relatively rotatable, that is, the vehicle The wheel holding unit that is not rotatable by the wheel 101 can be applied to the first switching member 75 and the second switching member 80, and the above-described effects of the first switching member 75 and the second switching member 80 can be obtained. Further, in the present embodiment, the wheel holding unit 100 has been described as being exemplified by the first switching member 75 and the second switching member 80. However, the present invention is not limited thereto. The wheel holding unit 100 may have only the second switching member 80. In this example, the above-described effects of the second switching member 80 can be obtained.

<<Switching mechanism>>

Next, the switching mechanism 88 will be described.

By the potential energy from the potential energy member 85, the cam receiving surface 81 of the second switching member 80 and the cam abutting surface 76 of the first switching member 75 can be maintained in contact with each other. Further, in the present embodiment, as the handle 70 is swung, the position of the cam abutting surface 76 that is in contact with the cam receiving piece 81 changes, whereby the potential of the potential energy member 85 is counteracted, and the second switching member 80 slides. On the rear foot 21 .

As shown in Figs. 17 to 19, in the present embodiment, as the handle 70 is moved from the first position to the second position, the portion of the cam abutting surface 76 that is in contact with the cam receiving piece 81 is viewed from the side of the stroller 10. , will gradually separate from the shaking axis da. Therefore, when the handle 70 is swung from the first position to the second position, the second switching member 80 is slid upward on the rear leg 21. Conversely, when the handle 70 is swung from the second position toward the first position, the second switching member 80 slides downward on the rear leg 21.

The cam contact surface 76 of the first switching member 75 and the cam receiving piece 81 of the second switching member 80 are mainly designed to reduce the size of the first switching member 75. The cam contact surface 76 of the first switching member 75 and the cam receiving piece 81 of the second switching member 80 will be described in detail later.

The lock member 130 that operates in accordance with the sliding of the second switching member 80 is provided to the wheel holding unit 100. As described above, the wheel holding unit 100 includes a wheel 101, a rotating body rotating body 110 that supports the wheel 101, and at least one of the front leg 20 and the rear leg 21, and the rotating body is centered on the caster axis Ac. 110 is supported as a rotatable fixed body 105.

Act between the locked position and the unlocked position. In the present embodiment, the relay member 83 is provided in the rear leg 21. Further, the relay member 83 is connected to the second switching member 80, and is moved up and down in the rear leg 21 at the same time as the sliding of the second switching member 80 with respect to the rear leg 21. The transmission device 87 has a wire member 87b in which one end is attached to the relay member 83 and the other end is attached to the lock member 130, and a cylindrical member 87a that extends through the inside of the wire 87b. As shown in Fig. 19, one end of the cylindrical member 87a is held by the holding portion 84 provided at a position near the relay member 83 in the rear leg 21, and as shown in Figs. 25 and 26, the other end of the cylindrical member 87a is held. The holding portion 107 is provided at a position near the locking member 130 of the wheel holding unit 100. As a result, when the second switching member 80 slides with respect to the rear leg 21, the wire 87b moves into the cylindrical member 87a, and the locking member 130 connected to the other end of the wire 87b moves as the wire 87b moves.

On the other hand, in the present embodiment, as described above, the front leg 20 and the rear leg 21 are each provided with a wheel holding unit 100 having a function as a caster. Therefore, as shown in FIG. 5, a communication device 87 is provided between the relay member 83 and the wheel holding unit 100 for the front leg, and another communication device is provided between the relay member 83 and the rear wheel support unit 100. 87.

The wheel holding unit 100 is disposed on the left and right sides.

<Cam contact surface of the first switching member and cam receiving piece of the second switching member>

Here, mainly referring to FIG. 16 to FIG. 21, the cam contact surface 76 of the first switching member 75 and the cam receiving piece 81 of the second switching member 80 will be described in detail.

As described above, as the handle 70 is rocked, the position at which the cam receiving piece 81 is in contact with the cam abutting surface 76 is changed, whereby the biasing force is applied to the first switching member 75 by the potential energy member 85. 2 The switching member 80 slides on the rear leg 21. As shown in FIGS. 17 to 19, in the present embodiment, as the handle 70 is moved from the first position to the second position, the portion of the cam abutting surface 76 that is in contact with the cam receiving piece 81 is on the side of the stroller 10. Next, it will gradually separate from the shaking axis da. Therefore, when the handle 70 is swung from the first position to the second position, the second switching member 80 is slid upward on the rear leg 21. phase Conversely, when the handle 70 is swung from the second position to the first position, the second switching member 80 slides downward on the rear leg 21.

Further, in the present embodiment, the position of the cam receiving piece 81 that comes into contact with the cam abutting surface 76 also changes as the handle 70 swings. As shown in FIGS. 17 to 21, when the handle 70 is rocked in a certain direction with respect to the stroller body 11, the position of the cam receiving piece 81 which is in contact with the cam abutting surface 76 is moved from the cam abutting surface 76. The upstream side changes to the downstream side. That is, the cam abutting surface of the cam receiving piece 81 that is in contact with the cam abutting surface 76 moves in the same direction as the cam abutting surface 76 that operates with the handle 70. According to the above-described embodiment, as shown in FIG. 17, the cam abutting surface 76 of the first switching member 75 is rocked from the first position to the second position while the handle 70 is placed at the first position. It can be disposed at a position facing only one of the portions of the cam receiving piece 81 that is in contact with the second switching member 80, and as shown in FIG. 21, the cam is abutted while the handle 70 is placed at the second position. The surface 76 can be disposed at a position facing only one of the portions of the cam receiving piece 81 that is in contact with each other while the handle 70 is rocked from the first position toward the second position.

In other words, when the position of the cam receiving piece 81 that is in contact with the cam abutting surface 76 is not changed, for example, the first switching member 75 is further provided with the portion shown by the chain line in FIG. 21, and the first switching member 75 is required. The cam abutment surface 76 is made longer. Therefore, according to the present embodiment, the first switching member 75 of the switching mechanism 88 which is easily complicated can be reduced in size and weight, and as a result, the size and weight of the stroller 10 can be reduced. In particular, the vicinity of the rocking axis da of the handle 70 is arranged to be folded with the stroller 10, or the sheet support unit 40 and the tilting action of the cloth piece 150 are related to each other, and there are fewer space vacancies. Actually, as shown in FIG. 12, the operation member 35b of the state maintaining mechanism 35 is provided right behind the first switching member 75. In the illustrated example, interference with the operating member 35b occurs, so that the extended portion shown by the chain line in Fig. 21 cannot be substantially provided. That is, the configuration of the cam abutting surface 76 and the cam receiving piece 81 of the present embodiment is not limited to the size and weight of the stroller 10, and the degree of freedom in the overall design of the stroller 10 can be improved.

As a specific example of the above configuration, the cam receiving piece 81 of the second switching member 80 is the same as the cam abutting surface 76, and can be formed by a surface, more specifically, a curved surface, a flat surface, a folded surface, or the like. On the other hand, as illustrated, the cam receiving piece 81 of the second switching member 80 may have at least two cam receiving protrusions 82a and 82b that protrude toward the cam abutting surface 76 of the first switching member 75. The cam receiving protrusions 82a and 82b are disposed at positions separated by a moving path along with the cam abutting surface 76 that is swung with the handle 70. According to the rocking position of the handle 70, the cam that is in contact with the cam abutting surface 76 is received by the cam. The parts 82a, 82b can be changed. The design and manufacture of the cam receiving piece 81 having the cam receiving projections 82a, 82b is not integral to the cam receiving piece 81, but requires high precision only at the position where the cam receiving projections 82a, 82b. Therefore, the production of the cam receiving piece 81 can be easily performed.

In the illustrated example, the cam receiving projections 82a and 82b are formed by a single cam receiving piece 81 extending in a line shape, but the cam receiving projections 82a and 82b may be provided separately.

Further, when the handle 70 is disposed at a certain position between the first position and the second position, the cam abutting surface 76 preferably moves along the cam abutting surface 76. And it is in contact with the adjacent two cam receiving protrusions 82a, 82b at the same time. As described above, in the present embodiment, the second switching member 80 applies the potential energy member 85 to the first switching member 75 to impart potential energy. On the other hand, among the cam receiving pieces 81, the cam receiving protrusions 82a, 82b which will come into contact with the cam abutting surface 76 will change in a certain direction as the cam abutting surface 76 which operates together with the handle 70 moves in a certain direction. . Therefore, the cam abutting surface 76 is set to be in contact with the adjacent two cam receiving projections 82a, 82b, whereby when the cam receiving projections 82a, 82b which are in contact with the cam abutting surface 76 are changed, The case where the first switching member 75 and the second switching member 80 collide with each other by the potential member 85 is avoided. Further, when the handle 70 is rocked in the swingable range in one of the directions and is swung in the other direction, that is, when the handle 70 is moved from the first position to the second position and from the second position to the first position, The collision due to the collision of the cam abutting faces 76 toward the cam receiving projections 82a, 82b, or the cam receiving projections 82a, 82b contacting the end portions 76a, 76b of the cam abutting faces 76 and causing the punching is caused. , to ensure that the handle 70 is smoothly shaken.

In particular, in the illustrated embodiment, the cam receiving piece 81 of the second switching member 80 has two cam receiving projections 82a and 82b, and the two cam receiving projections 82a and 82b are in the handle 70. When the position moves toward the second position, the first cam receiving projection 82a on the upstream side of the moving passage of the cam abutting surface 76 and the second cam receiving projection 82b on the downstream side. In the state in which the handle 70 shown in FIG. 17 is disposed at the first position, the cam abutting surface 76 receives the projection only with the first cam among the first cam receiving projection 82a and the second cam receiving projection 82b. 82a is opposite and with the first The cam receiving protrusion 82a is in contact. Moreover, in the state in which the handle 70 shown in FIG. 21 is disposed at the second position, the cam abutting surface 76 receives the protruding portion only with the second cam among the first cam receiving protruding portion 82a and the second cam receiving protruding portion 82b. The opposite side of the 82b is in contact with the second cam receiving projection 82b. According to the above-described embodiment, the position in contact with the cam abutting surface 76 of the cam receiving piece 81 changes in accordance with the movement of the cam abutting surface 76, so that the length of the cam abutting surface 76 can be shortened. In other words, the first switching member 75 of the switching mechanism 88 which is easily complicated can be reduced in size and weight, and as a result, the stroller 10 can be reduced in size and weight. In short, as described above, the configuration of the cam abutting surface 76 and the cam receiving piece 81 of the present embodiment can increase the degree of freedom in the overall design of the stroller 10.

Further, according to the present embodiment, when the handle 70 is disposed at the first intermediate position shown in FIG. 18 between the first position of FIG. 17 and the second position of FIG. 21, the cam abutting surface 76 is received by the first cam. Both of the protruding portion 82a and the second cam receiving protruding portion 86b face each other and are in contact only with the first cam receiving protruding portion 82a. On the other hand, when the handle is disposed at the second intermediate position shown in FIG. 20 between the first intermediate position of FIG. 18 and the second position of FIG. 21, the cam abutting surface 76 and the first cam receiving projection 82a. Both of the second cam receiving projections 82b are opposed to each other and are in contact with only the second cam receiving projection 82b. According to the above-described embodiment, the cam abutting surface 76 can set a timing point at which the adjacent two cam receiving projections 82a and 82b are simultaneously contacted. That is, when the handle 70 is disposed at the position shown in FIG. 19 between the first intermediate position of FIG. 18 and the second intermediate position of FIG. 20, the cam abutting surface 76 can receive the protruding portion 82a and the second cam with the first cam. The two sides of the cam receiving projection 82b are in contact. According to the above As described above, when the cam receiving projections 82a and 82b which are in contact with the cam abutting surface 76 are changed, the collision of the cam abutting faces 76 of the cam receiving projections 82a and 82b does not occur, or When the cam receiving projections 82a and 82b are in contact with the end portions 76a and 76b of the cam abutting surface 76 and the punching is generated, the smooth movement of the handle 70 can be ensured.

However, since the cam abutting surface 76 and the cam receiving piece 81 are realized as described above, in the present embodiment, when the handle 70 is viewed with respect to the rocking axis da of the stroller body 11, the handle 70 is opposed to the stroller body. The linear distance La from the respective positions of the rocking axis da to the cam abutting surface 76 is from the first end 76a of the cam abutting surface 76 on the front side in the moving direction when the handle 70 is swung from the first position to the second position toward the moving direction. The other end 76b of the cam abutting surface on the rear side gradually becomes longer, and when the handle 70 is disposed at the second position shown in FIG. 21, the swinging axis da from the handle 70 with respect to the stroller body 11 is 2nd. The linear distance Lb of the cam receiving projection 82b is shorter than the linear distance Lc from the handle 70 with respect to the rocking axis da of the stroller body 11 to the first cam receiving projection 82a.

Further, in the present embodiment, when the handle 70 is viewed with respect to the rocking axis da of the stroller body 11, the straight line distance La from the rocking axis da of the handlebar 70 to the cam abutment surface 71 of the stroller body 11 is observed. When one of the handles 70 is swung from one side to the other side, the one end 76a of the cam abutting surface 76 on the front side in the moving direction faces the other end 76b of the cam abutting surface on the rear side in the moving direction, and Gradually becoming longer, and as shown in FIG. 16, the width w of the cam abutting surface 76 in the direction parallel to the rocking axis da of the handle 70 will be from the one end 76a of the cam abutting surface 76 toward The other end 76b of the cam abutting surface 76 toward the rear side in the moving direction is gradually widened. According to the above embodiment, the width w of the cam abutting surface 76 is widened at a position on the cam abutting surface 76 where the linear distance La of the rocking axis da of the handle 70 becomes longer from the side view. When the linear distance La from the rocking axis da of the handle 70 to a position on the cam abutting surface 76 becomes longer, the position of the cam abutting surface 76 comes into contact with the cam receiving piece 81, from the cam receiving piece The potential energy of the energizing potential member 85 that gives the potential energy toward the cam abutting surface 76 becomes larger. Further, since the width w of the cam abutting surface 76 at a position where the linear distance La from the rocking axis da of the handle 70 becomes longer becomes wider, the larger potential energy from the potential energy guiding member 85 can be abutted in the cam abutting surface 76. A wider width part is to be taken. In other words, the size of the first switching member 75 and the stroller 10 can be reduced and reduced without requiring the size of the cam abutting surface 76 to be more than necessary. Moreover, the relative movement between the first switching member 75 and the second switching member 80 that is swung with the handle 70 can be made smoother.

<Locking member and wheel holding unit>

Next, referring mainly to FIGS. 25 to 27, a description will be given of a portion of the shaft member 130 and the wheel holding unit 100 that is associated with the locking member 130.

As described above, the locking member 130 is movable between a locking position of FIG. 26 that restricts the rotation of the rotating body 110 with respect to the fixed body 105, and a locking release position of FIG. 25 that allows the rotating body 110 to be rotated relative to the fixed body 105. . As shown in FIGS. 25 and 26, the fixed body 105 is formed with an accommodating portion 106 that extends in one direction and that is open on one side of the aforementioned direction opposite to the rotating body 105. In the present embodiment, the accommodating portion 106 extends in the vertical direction and opens downward in the vertical direction. On the other hand, the branch of the rotating body 110 The holding block 115 is formed with an engaging recessed portion 114 at a position that can face the receiving portion 106 of the fixed body 105 in one direction.

The lock member 130 has its longitudinal direction disposed in the accommodating portion 106 in one direction, and is slidable in the accommodating portion 106. The position where the locking member 130 moves in the one side of the accommodating portion 106 in one direction is the unlocking position shown in FIG. 25, and the locking member 130 is spanned over the entire length of the locking member 130 and located in the accommodating portion 106 of the fixed body 105. . Therefore, when the locking member 130 is in the unlocked position, the locking member 130 does not restrict the rotation of the rotating body 110 with respect to the fixed body 105. On the other hand, the position in which the locking member 130 moves in one of the directions in the accommodating portion 106 is the locking position shown in FIG. 26, and the locking member 130 is in the locking position, and one of the ends thereof extends outside the accommodating portion 106. Go out. At this time, one of the ends of the locking member 130 extends into the engaging recess 114 of the rotating body 110. Therefore, when the locking member 130 is in the locked position, the locking member 130 limits the rotation of the rotating body 110 relative to the fixed body 105.

As shown in FIGS. 25 and 26, in the accommodating portion 106 of the fixed body 105, a compression spring 103 is disposed at a position on one side of the locking member 130. The compression spring 103 is compressed between the one end surface of the accommodating portion 106 and the locking member 130, whereby the locking member 130 is given potential energy from the other side in one direction toward the other side. As described above, the locking member 130 is connected to the wire 87b of the conveying device 87. Further, as the wire 87b that is shaken by the handle 70 moves, the locking member 130 is pulled up against the potential energy of the compression spring 103, whereby the locking member 130 is moved from the locked position toward the unlocked position. On the other hand, as the wire 87b that is shaken by the handle 70 moves, the potential energy of the compression spring 103 is utilized. The locking member 130 is pushed down, whereby the locking member 130 is moved from the unlocked position toward the locked position.

However, the locking member 130 of the present embodiment includes a spring receiving surface 131a that receives one of the ends of the compression spring 103. Further, the locking member 130 has a direction extending toward the other side of the spring receiving surface 131a and is located at the compression spring. The spring side extension 135 on the side of the 103. As shown in FIG. 25, when the locking member 130 slides in one of the directions in the accommodating portion 106 and is in the unlocked position, the length of the spring-side extending portion 135 is longer than the one of the spring receiving surface 131a and the accommodating portion 106. The length of the compression spring 103 compressed between the end faces is shorter. The lock member 130 can be made longer by using the region where the compression spring 103 is disposed without lengthening one of the directions of the accommodating portion 106. In other words, the locking member 130 can be made longer without increasing the size and weight of the wheel holding unit 100. Further, by making the locking member 130 long, even if a gap for ensuring that the locking member 130 is surely slid is provided between the locking member 130 and the accommodating portion 106, the locking member 130 in the accommodating portion 106 can be effectively suppressed. When it is shaken, the smooth sliding action of the locking member 130 can be achieved. Thereby, the state in which the rotating body 110 is rotatable with respect to the fixed body 105 and the state in which the rotating body 110 is not rotatable with respect to the fixed body 105 can be performed more reliably.

Further, in the present embodiment, as shown in FIG. 27, the spring-side extension portion 135 has a pair of side wall portions 136 and a connection wall portion 137 that connects the pair of side wall portions 136. A portion of one side of at least one direction of the compression spring 103 is surrounded by the spring side extension portion 135 from three sides. Therefore, as the compression member 103 of the locking member 130 slides in the accommodating portion 106 compresses and expands, the bomb is utilized. The spring side extension portion 135 guides. Thereby, the sliding action of the locking member 130 in the accommodating portion 106 is more stable. For example, when the lock member 130 is moved from the lock position to the lock release position, the compression spring 103 receives the compressive force, but at this time, the compression spring 103 can be effectively prevented from buckling and protruding in a direction orthogonal to one direction. Thereby, the sliding action of the locking member 130 in the accommodating portion 106 is more stable.

Further, in the present embodiment, as shown in FIGS. 25 to 27, the lock member 130 has a base portion 131 that forms the spring receiving surface 131a and is connected to the spring side extension portion 135, and a base portion 131 that is connected to the base portion 131. A wheel side extension 141 that extends out of one side of the direction. Further, the end portion of the wire 87b of the transmission device 87 is attached to the base portion 131. Further, the wheel side extension portion 141 has a pair of side wall portions 142 and a connection wall portion 143 that connects the pair of side wall portions 142. The locking member 130 achieves a smooth sliding in the accommodating portion 106 by securing the entire length thereof, and can be made lighter.

Further, according to the present embodiment, as shown in FIGS. 25 to 27, the wheel side extension portion 141 has a tip end tapered end portion 141a at one end in one direction. According to the above-described locking member 130, one end of the locking member 130 can extend from the receiving portion 106 of the fixed body 105 and smoothly enter inwardly in the engaging recess 114 of the rotating body 110. That is, the sliding from the lock releasing position of the lock member 130 toward the lock position can be made smoother.

Further, according to the present embodiment, as shown in Figs. 25 to 27, in addition to the distal end taper portion 141a of the wheel side extension portion 141 of the lock member 130, the engagement recess portion 114 has a tip end which is tapered at one end in one direction. Bottom taper portion 114a. According to the above-described wheel holding unit 100, the slave locking member 130 can be The sliding of the lock release position toward the lock position is rounded, and the gap between the lock member 130 and the engagement recess 114 when the lock member 130 is in the lock position is reduced. Therefore, the rotating body 110 can smoothly move from the rotatable state to the state in which the rotating body 110 is rotated relative to the fixed body 105 with respect to the fixed body 105, and thereafter effectively prevents the rotating body 110 from shaking with respect to the fixed body 105. . Thereby, the stable walking of the stroller 10 can be achieved.

Further, according to the present embodiment, as shown in Figs. 25 to 27, the compression spring 103 is a compression coil spring, and the wire 87b attached to one of the end portions of the base portion 131 of the lock member 130 forming the spring receiving surface 131a is penetrated. The coil spring 103 is compressed and extended. According to the wheel holding unit 100 described above, the compression and expansion of the compression coil spring 103 that slides in the housing portion 106 of the lock member 130 are guided by the wire 87b and the spring side extension portion 135. Therefore, the sliding motion in the housing portion of the locking member 130 is more stable.

However, in the present embodiment, the example in which the lock member 130 is transmitted through the transmission device and automatically operates in accordance with the movement of the handle 70 has been described, but is not limited thereto, and the wheel holding unit 100 associated with the lock member 130 and the lock member 130 is not limited thereto. The configuration of the wheel holding unit that is manually operated can be applied to the above-described example, and the effect of the configuration of the wheel holding unit 100 associated with the lock member 130 and the lock member 130 can be exhibited.

<<布片150>>

Next, the cloth sheet 150 supported on the sheet supporting unit 40 will be described mainly with reference to FIGS. 1 , 2 and 28 to 30 . As shown in detail in Fig. 28, the panel piece 150 is entirely centered on the center plane in the width direction extending in the front-rear direction. It becomes a roughly symmetrical structure.

As shown in FIG. 1, FIG. 2, and FIG. 28 to FIG. 30, the panel piece 150 has a seat portion 156, a backrest portion 157 that is connected to the seat portion 156 and located behind the seat portion 156, and extends from the seat portion 156 toward both sides. The left and right side surface portions 160 and the left and right upper side surface portions 167 extending from the backrest portion 157. The seat portion 156 will primarily support the buttocks of infants riding the stroller 10. On the other hand, the backrest portion 157 is disposed at a position opposite to the back of the infant. The side surface portion (first side surface portion) 160 and the upper side surface portion (second side surface portion) 167 constitute a side wall portion on the side of the infant. Further, the cloth piece 150 further has an upper portion 169 that is connected to a position that is separated from the seat surface portion 156 of the backrest portion 157. As shown in FIG. 4, the upper portion 169 connects the left and right upper side surface portions 167 and has a function as a headrest.

As described above, the seat portion 156 is mainly supported by the seat surface support member 50 of the panel support unit 40. As shown in Fig. 28, the rear edge portion of the seat portion 156 is connected to the backrest portion 157, and the pair of side edge portions are connected to the side surface portions 160 on the respective sides. The backrest portion 157 is mainly supported by the backrest support member 60 of the panel support unit 40. As shown in FIG. 28, the backrest portion 157 has a substantially chamfered shape in a plan view, and one of the rectangular shapes has a curved shape. The backrest portion 157 is disposed such that the curved edge portion is formed to be separated rearward or upward from the seat portion 156.

The backrest portion 157 is connected to the rear edge portion of the seat portion 156 at a lower edge portion thereof. The backrest portion 157 and the seat portion 156 are connected to each other by, for example, stitching. At this time, the joint between the backrest portion 157 and the seat portion 156 is divided by a stitch line extending in a line shape. With the tilting or folding action of the stroller body 11, The seat portion 156 and the backrest portion 157 of the panel 150 are close to each other. At this time, the linear connection between the seat portion 156 and the backrest portion 157 by the sewing line is a rocking axis, and can be relatively rocked.

Each of the pair of side edge portions of the backrest portion 157 is connected to each of the upper side surface portions 167.

Further, an upper portion 169 having a function as a headrest is connected to the curved upper edge portion of the backrest portion 157. The pair of upper side portions 167 are supported by the side support members 45 of the panel support unit 40, and the upper portion 169 is supported by the upper support members 41 of the panel support unit 40. In the example shown in Fig. 28, the pair of upper side surface portions 167 and the upper portion 169 are integrally formed by the same material. In this example, the pair of upper side surface portions 167 and the upper portion 169 are connected to the backrest portion 157 by, for example, sewing. At this time, the upper side surface portion 167 and the joint portion between the upper portion 169 and the backrest portion 157 are drawn by a sewing line extending in a substantially U-shape. As described above, the upper support member 41 can be rocked with respect to the backrest support member 60. With the rocking of the backrest supporting member 60 with respect to the upper supporting member 41, the upper portion 169 is a rocking axis formed by the sewing line, and is rocked with respect to the backrest portion 157.

On the other hand, as can be understood from FIGS. 1 and 2, the side support member 45 can be maintained in a state of being established with respect to the surface drawn by the backrest support member 60 without depending on the tilting operation. Therefore, the upper side portion 167 supported by the side support members 45 stands up on the side of the infant leaning against the backrest portion 157 without relying on the tilting action. The upper side portion 167 has a wider width above the side of the infant's head. On the other hand, there is a narrow width below the seat surface 156, as can be understood from FIG. 29 and FIG. It is configured such that it does not interfere with the approach of the seat portion 156 to the backrest portion 157.

The seat portion 156, the backrest portion 157, the upper side surface portion 167, and the upper portion 169 are in direct contact with the infant who rides the stroller 10. Therefore, the seat surface portion 156, the backrest portion 157, the upper side surface portion 167, and the upper portion 169 are formed of a cushioning cloth. For example, a cloth having a cushioning sponge or the like sandwiched between two sheets of cloth can be used. A material or a cloth having a cushioning property is composed of a cloth material.
