Description

Baby carriage Field of invention

The present invention relates to a stroller including a stroller body, a seat having a seat portion and a reclinable back, and being mounted on a seat member of the stroller body, and particularly effective in a rearward state. A stroller that prevents the back from shaking.

Background of the invention

It is known that a baby carriage is known to the infant to ride, and includes a stroller body, a seat member having a seat and a back, and being mounted on the body of the stroller. Most of the strollers currently in use are constructed such that the back can be reclined. Most of the seat members are composed of a core material and a mat material covering the core material, and the seat portion and the back portion of the seat member are supported by the stroller body with the edge portion fixed and suspended from the stroller body.

Such a stroller, as described in paragraphs 0053 and 0054 of JP2010-538923T, pulls the back up by shortening the hanging amount from the stroller body, and approaches the stroller body to stand up. On the contrary, by increasing the amount of hanging from the body of the stroller, the back is turned to the rear, and the distance between the body of the stroller and the body of the stroller can be reversed.

However, since the above-described conventional rearward tilting mechanism is tilted from the stroller body to the rear in a state where the back is greatly tilted from the stroller body to the rear, the back is easily swung in the width direction (horizontal direction) of the stroller body. (vibration). Such a shaking of the back deteriorates the ride of the infant in the stroller, and also deteriorates the maneuverability of the operator (user, protector) who operates the stroller.

Further, in the present embodiment, the stroller 10 is configured to be foldable as shown in JP2010-132077A. Further, as shown in Fig. 2, a belt 18 for carrying the stroller 10 in a folded state is provided in the stroller body 20.

In this specification, the terms "before", "after", "right", "left", "horizontal", "upper" and "lower" used in the stroller 10 and its constituent elements are not specifically indicated. They are referred to as "before", "after", "right", "left", "horizontal", "upper" and "lower" based on the infants who are riding on the baby carriage 10 in the unfolded state. In addition, the "width direction" used for the stroller 10 and its constituent elements means the direction in which "left" and "right" are connected, that is, "horizontal direction", and the "traveling direction" used for the stroller 10 and its constituent elements. Means the direction of linking "before" and "after".

As shown in FIG. 1 to FIG. 8 , the stroller 10 of the present embodiment is formed so as to be substantially symmetrical about the entire surface (the horizontal direction of the front-rear direction) passing through the center in the lateral direction (the front-rear direction). The structure. In other words, the stroller body 20, the seat member 50, and the hood 80 are each configured to be substantially symmetrical about the center plane in the lateral direction of the traveling direction (front-rear direction). Among them, first explained from the stroller body 20.

The stroller body 20 has left and right handles 25, left and right forefoot 30, and left and right rear legs 35. The constituent elements constituting the stroller body 20 are coupled to be rotatable and foldable. As shown in Fig. 3, the upper end portion of the front leg 30 is rotatably coupled to the lower end portion of the handle 25 on the corresponding side. The upper end portion of the rear leg 35 is rotatably coupled to the upper portion of the handle 25 on the corresponding side. The front wheel 31 is rotatably provided at a lower end portion of each of the front legs 30. Further, the rear wheel 36 is rotatably provided at a lower end portion of each of the rear legs 35. A handle 26 for gripping property is provided on the upper end portion of the handle 25.

A left and right coupling frame 34 and a link member 38 are provided between the front leg 30 and the rear leg 35. The left side link frame members 34 are rotatably coupled to the left front foot 30 and the left rear leg 35, respectively. The right side connecting frame members 34 are rotatably coupled to the right front foot 30 and the right rear side 35, respectively. Each of the joint frames 34 is joined to the corresponding side rear leg 35 at its rear end portion. On the other hand, the front end portion of each of the joint frame members 34 extends beyond the joint between the joint frame 34 and the front leg 30 and extends forward.

On the other hand, the link member 38 has the first link member 38a and the second link member 38b. The first link member 38a extends between the lower end portion of the left forefoot 30 and the lower end portion of the right rear leg 35, and the second link member 38b extends between the lower end portion of the right forefoot 30 and the lower end portion of the left rear leg 35. The first link member 38a is connected to the left forefoot 30 and the right rear leg 35 so as to be rotatable about two axes that can be crossed. Therefore, the first link member 38a can perform not only the rotation of the left front foot 30 and the right rear leg 35 in the two-dimensional plane, but also the rotation in each direction in the three-dimensional space. Similarly, the second link member 38b is connected to the right forefoot 30 and the left rear leg 35 so as to be rotatable about two axes that can be crossed.

Further, the intermediate portion of the first link member 38a is pivotally connected to the intermediate portion of the second link member 38b. Therefore, the first link member 38a and the second link member 38b can be rotated to each other, and the end portions of each other can be brought close to each other from the state in which the interval is opened (X-shaped) or the end portions of each other are close to each other (I Glyph) Open the gap.

Further, as shown in Fig. 1, a footrest 32 is provided as a member that connects between the pair of front legs 30. The two ends of the pedal 32 are fixed to the lower end portion of the left front foot 30 and the lower end portion of the right front foot 30, and the support is placed on the stroller body 20. The foot 32 is made of a soft material (soft material) such as cloth, leather, or rubber, and is configured to have flexibility.

Further, as shown in Fig. 2, the first rear strut 37a and the second rear strut 37b are provided as members that connect the pair of rear legs 35. The second rear strut 37 is fixed at its lower end to the lower portion of the left rear leg 35 and to the lower portion of the right rear leg 35. The first rear strut 37a is positioned above the second rear strut 37b, and its both ends are fixed to the left rear leg 35 and the right rear leg 35. Each of the first rear strut 37a and the second rear strut 37b is configured to be bendable, and may be in a state of being extended in the width direction and being bent in a state in which both ends are close to each other in the width direction.

The above is the main structure of the stroller body 20. The stroller body 20 is centered on the pivot point PP1 of the handle 25 and the front leg 30, and the front leg 30 is rotated against the handle 25, whereby the folded state can be folded from the unfolded state. During the folding operation, after the connecting frame member 34 is coupled to the forefoot 30, the foot 35 is rotated about the handle 25 by the forefoot 30, and is rotated about the pivot point PP2 of the handle to access the handle 25. As a result, as shown in FIG. 4, the front body 30, the handle 25, and the rear leg 30 are overlapped, and the stroller body 20 is folded, and in the folded state, the outer size (outer contour) of the stroller body 20 viewed from the side can be greatly increased. miniaturization.

Further, from the comparison between the unfolded state shown in Fig. 3 and the folded state shown in Fig. 4, it can be understood that as the transition from the unfolded state to the folded state, the lower end portion of the forefoot 30 and the lower end portion of the rear leg 35 are mutually pulled. Open interval. As a result, the link member 38 provided between the lower end portion of the front leg 30 and the lower end portion of the rear leg 35 is deformed from the X-th shape to the I-shape by the folding operation, and the length of the side view is increased. Thereby, the left side constituent elements (the handle 25, the front leg 30, and the rear leg 35) of the stroller body 20 and the right side constituent elements (the handle 25, the front leg 30, and the rear leg 35) are close to each other. As a result, in the folded state, the outer size (outer contour) of the stroller body 20 viewed from the front, that is, the outer dimension (outer contour) in the width direction can be greatly miniaturized.

Further, when the left side constituent element of the stroller body 20 is in close proximity to the right side component, the pedal 32 connecting the left and right forefoot 30 is bent or bent, and the first rear strut between the left and right rear legs 35 and the second rear are connected. The struts 37a, 37b are bent. Therefore, the members 32, 37a, and 37b that connect the left and right constituent elements are prevented from being shrunk in the width direction.

In the folded state, the stroller 39 of the stroller body 20 is engaged with the forefoot 30 by the hook 39 of the rear leg 35, and can be maintained in the folded state. On the other hand, as shown in Fig. 2, the stroller body 20 in the deployed state can be maintained in the deployed state by the locking mechanism 24 coupled to the first rear strut 37a and the second rear strut 37b. This locking mechanism 24 maintains the first rear strut 37a and the second rear strut 37b in a state of being elongated in the width direction. In other words, the locked state in which the first rear strut 37a and the second rear strut 37b cannot be bent and the released state in which the first rear strut 37a and the second rear strut 37b are bendable can be adopted. Further, by switching the lock device 24 to the released state, the folding operation from the unfolded state to the folded state can be performed.

Next, the hood 80 will be described. The hood 80 is used as a sunshade and shelter for infants riding on the stroller 10. In the present embodiment, the hood 80 is detachably fixed to the handle 25 of the stroller body 20.

The hood 80 has a plurality of hood bones 81 forming a U shape and a tarpaulin 83 attached to the hood bone 81. Each of the car bonnets 81 is rotatably coupled to other hood bones at the end portions of the U-shape. In the examples shown in Figs. 1 and 2, two canopies 81 are provided. The tarpaulin 83 is attached to the hood shaft 81 in a state of being supported by the two hood bones 81 which are pivoted to each other at a position apart from each other. Therefore, the hood 80 can be opened and closed by rocking (rotating) the hood 81.

The hood 81 of the hood 80 is formed of an elastic body made of a resin-made thin plate or a metal thin plate. Further, the tarpaulin of the hood 80 is formed of a soft cloth such as cloth or vinyl. Therefore, with the folding operation of the stroller body 20 described above, the hood bone 81 and the tarpaulin 83 are deformed following the deformation of the stroller body 20, and the hood 80 is also shrunk. Further, with the unfolding operation from the folded state to the unfolded state, the elastic deformation of the canopy 81 is released, and the hood 80 can be automatically expanded.

Next, the seat member 50 will be described. The seat member 50 is a member that is placed in contact with an infant of the stroller 10. The seat member 50 has a seat portion 51 in which the buttocks of the infant can be contacted and a back portion 53 that contacts the back of the infant. In the middle, the back portion 53 has a back surface portion 53a that contacts the back of the infant from the rear, and left and right side surface portions 53b that face the infant from both sides. The back portion 53a of the back portion 53 is connected to the seat portion 51 from above. Each side surface portion 53b of the back portion 53 is connected to the seat portion 51 from above, and is connected to the back surface portion 53a from the front. Further, as shown in Fig. 1, the seat member 50 is provided with a seat belt 57 for stably supporting the infant to the seat member.

The seat member 50 is formed using a soft cloth such as a cloth, a mesh material, or a leather. In particular, the seat portion 51 for supporting the weight of the infant and the back portion 53a of the back portion 53 are formed of a plate-shaped core material and a cloth material covering the core material, preferably a cushioning cloth. Further, the seat member 50 is also configured to be deformable in accordance with the deformation of the stroller body 20 during the folding operation and the unfolding operation of the stroller. Therefore, when the core material is used for the seat member 50, a crease or a slit may be formed in advance in the core material.

In the example shown in the drawing, the seat member 50 is fixed to the joint frame member 34, the front leg 30, and the handle 25 of the stroller body 20. More specifically, as shown in FIGS. 5 and 6, the edge portion of the seat portion 51 of the seat member 50 in the width direction is fixed to the left and right coupling frame members 34 including the portions extending to the front side of the front leg 30. The former portion is supported (suspended) in a state of being suspended between the left and right link frame members 34. Further, the left and right side surface portions 53b of the seat member 50 are fixed to the corresponding side handle 25 and the forefoot 30 at a portion above the coupling frame 34, and are supported by the handle 25 and the front leg 30. (hanging). On the other hand, although the back surface portion 53a of the seat member 50 is not directly fixed to the stroller body 20, it is suspended and supported by the stroller body 20 by the adjacent seat portion 51 and the left and right side surface portions 53b.

The back surface portion 53a of the back portion 53 is rotatably coupled to the seat portion 51, and the side surface portion 53b of the back portion 53 is deformed in accordance with the rotation of the seat portion 51 by the back surface portion 53a. Therefore, the back 53 of the seat member 50 can be reclined. Further, as shown in FIGS. 5 to 8 , the stroller 10 is further provided with an adjustment mechanism 60 for adjusting the back angle of the back 53.

The adjustment mechanism 60 has a first member 61 that is fixed to the mounting portion 61a of the stroller body 20 or the seat member 50, and a sliding portion 61b that is movably passed through the insertion path 56 formed in the back portion 53 and slidable toward the back portion 53, And the second member 64 that fixes the first member 61 to the back portion 53. In the present embodiment, the first member 61 fixes the attachment portion 61a to the handle 25 of the stroller body 20 by caulking. Further, as shown in FIGS. 7 and 8, the first member 61 is configured as an elongated member having a belt-shaped proximal end side portion 62a and a string-like distal end side portion 62b.

In the example shown in the drawing, the first members 61 are respectively extended from the respective handle members 25. The pair of first members 61 respectively extend along the side surface portions 53b on the corresponding side of the back portion 53, and merge at the back surface portion 53a of the back portion 53. In the back surface portion 53a of the back portion 53, the cloth material 55 is sewn to the cloth material as the base of the back surface portion 53a, and the sliding portion 61b of the first member 61 is slidably inserted between the cloth material 55 and the cloth material as the base material. The insertion path 56. Further, a through hole 55a penetrating the insertion path 56 is formed in the center of the cloth member 55, and the pair of first members 61 are merged and passed through the through hole 55a, and are passed out from the inside of the insertion path 56 to the outside.

The second member 64 is configured as a fixture that bundles and fixes the first member 61 from the through hole 55a of the back portion 53. The second member 64 fixes the first member 61 to the back portion 53 so that the first member 61 passing through the insertion path 56 of the back portion 53 can be prevented from being pulled back into the insertion path 56. Therefore, as shown in FIG. 5 and FIG. 7, the first member 61 is fixed to the first member 61 by the second member 64 in a state where the first member 61 is pulled out from the through hole 55a formed in the back surface portion 53a of the back portion 53 of the seat member 50. The member 61, by which the back portion 53 can be raised against the seat portion 51. On the other hand, as shown in FIGS. 6 and 8, the restraint of the second member 64 is released, and the first member 61 is returned to the insertion path 56 side by the through hole 55a, whereby the back 53 can be seated. The section 51 is dumped. That is, in the stroller 10 of the present embodiment, it can be easily understood from the comparison shown in Figs. 7 and 8, whereby the adjustment mechanism 60 winds up or discharges the side surface portion 53b of the back portion 53 of the seat member 50, which is adjustable. The back 53 is tilted from the back portion 53a of the stroller body 20 to adjust the back angle of the back 53.

According to this aspect, the amount of hanging of the back surface portion 53a of the side surface portion 53b is ensured by the hanging amount, and the back portion 53 of the seat member 50 can be largely tilted against the seat portion 51. At this time, the back side portion 53a of the infant seated on the stroller 10 is supported from the rear side to prevent the rear side from collapsing by the left and right side surface portions 53b. However, in the conventional stroller, there is a drawback in that the back surface portion of the seat member is swung in the width direction (lateral direction).

On the other hand, in the present embodiment, the stroller 10 is provided with a support member 75 extending to the side of the back 53 of the seat member 50 and a connecting member 70 attached to the back 53 of the seat member 50. Further, the connecting member 70 is connected to the supporting member 75 so as to be slidable against the supporting member 75 in accordance with the action of the back portion 53. According to this embodiment, although the back portion 53 of the seat member 50 is attached to the support member 75 located at the side of the back portion 53 by the connecting member 70, the back portion 53 is restricted from being free in the width direction. mobile. As a result, even when the back portion 53 is largely inclined to the seat portion 51, it is possible to effectively prevent the back portion 53 from being shaken (vibrated) in the width direction (lateral direction).

Specifically, in the present embodiment, the support member 75 is formed of a belt member (elongated member) which is formed of a cloth material, leather, rubber or the like and has flexibility. Further, in the example shown in the drawing, the support members 75 each formed of an elongated shape are provided on both sides of the back portion 53, respectively. Each of the support members 75 is fixed to the stroller body 20 by riveting at both ends. The left side support member 75 is fixed to the left side handle 25 and the left side rear leg 35, and extends between the left side handle 25 and the left rear leg 35. Similarly, the right side support member 75 is fixed to the right side handle 25 and the right side rear leg 35, and extends between the right side handle 25 and the right rear leg 35. In the example shown in the drawing, each of the support members 75 is attached to the handle 25 at a position where the handle 25 is joined to the forefoot 30 and the joint between the handle 25 and the rear leg 35. Further, each of the support members 75 is attached to the rear leg 35 at a position where the rear leg 35 is coupled to the handle 25 and a position between the rear leg 35 and the connecting frame member 34.

According to this aspect, since the support member 75 is made of a soft material and can be bent or bent, the folding operation of the stroller 10 is not hindered by the provision of the support member 75. In other words, since the support member 75 has flexibility to be deformed to follow the folding operation of the stroller body 20, the folding operation of the stroller 10 can be smoothly performed.
