BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a baby carriage used for taking an infant outdoors for walking, shopping, and the like, and more particularly to a hammock type baby carriage in which a seat for carrying an infant is suspended on a baby carriage body.

In this type of hammock type stroller, a seat is attached to the handle lever of the stroller main body and the left and right connecting bars (left and right bars connecting the front and rear legs). More specifically, the seat back part is attached to the left and right handle pipes of the handle lever, and the seat part of the seat is attached to the left and right connecting bars. In addition, the lower surface of the seat of the seat is supported by a stay provided so as to connect the left and right connecting bars to each other.

Here, in the hammock-type stroller as described above, when the seat portion of the seat is supported only by the same stay as described above, there is a fear that the seat portion of the seat may swing back and forth around the stay. For this reason, in the conventional hammock type baby carriage, generally, the support belt which supports the lower surface of the seat part of a seat with a stay is again tightened in the left and right connection bars, and the seat part of a seat is prevented from rocking | swinging.

In addition, in the hammock type stroller in the related art, it is also proposed that the angle of inclination of the back (backrest and headrest) of the seat attached to the stroller body can be changed. That is, the reclining angle changing belt is provided in the handle pipes on the left and right sides of the handle levers to support the backrest portion corresponding to the back of the infant, and the backrest is adjusted by adjusting the length of the reclining angle changing belt. It is proposed that the negative inclination angle can be changed. Moreover, in such a hammock type baby carriage, the head pipe (part connected to the upper edge part of the back part) corresponding to the infant's head part of the seat of the seat is supported on the left and right handle pipes of the handle lever. When the headrest support belt having a constant length is further provided and the reclining angle changing belt length is adjusted to reduce the inclination angle of the backrest portion, the headrest is raised to the backrest portion.

Moreover, in the hammock type stroller of the related art, it is known that the sheet | seat which an infant can ride is comprised from the base sheet attached to the stroller main body, and the detachable sheet | seat placed on a base sheet. Among them, the base seat has a base seat portion and a base back portion, the detachable seat has a seat portion and a back portion, and the seat portion of the detachable seat is supported by the base seat portion so that the back portion of the detachable seat is supported by the base back portion.

However, in such a hammock type baby carriage, when the baby carriage main body is in a small folded state (such as a three-stage folding state), movement (bending operation) of each part of the baby carriage main body is interrupted by the support belt, and the baby carriage main body is folded small. There is a problem that a large operation force is required to bring it into a state. In addition, this problem can be solved once by setting the support belt a little longer, but in this case, the support of the seat is not sufficient when the stroller is used, and a problem such as a large depression occurs at the rear of the seat when an infant is carried. There was.

In the conventional hammock type stroller, the reclining angle changing belt and the headrest support belt provided on the left and right handle pipes of the handle lever adjust the length of the reclining angle changing belt to reduce the inclination angle of the backrest portion. In other words, the head restraint of the infant seated on the seat can be protected by allowing the headrest to stand up against the backrest. However, in such a hammock-type stroller, the reclining angle changing belt and the headrest support belt are provided in the handle pipes on the left and right sides of the handle lever as separate members, so that they are prepared and placed on the back of the seat (backrest and headrest). There is a problem such as the cost of sewing.

In addition, in the conventional hammock type baby carriage, since the sheet (particularly the base sheet) is made of a thick synthetic resin material, there is a problem in breathability, and there is a problem that infants burned on the sheet are likely to sweat.

<First Embodiment>

First, the hammock type baby carriage according to the first embodiment of the present invention will be described with reference to FIGS.

As shown in FIG. 1, the baby carriage 10 according to the first embodiment of the present invention is a seat for fastening an infant from a baby carriage body, and has a twin wheel type front wheel 11 mounted left and right. A pair of left and right pairs of rear legs 14 equipped with a pair of front legs 12, a rear wheel 13 of a two-wheel type, a handle lever 15 bent in a substantially inverted U shape, and a pair of left and right arm rests (16) and a detachable guide arm (17) sandwiched between the arm rests (16), and the stroller body (10a) is formed by each of these members.

Here, the handle lever 15 is for transmitting a force to the left and right front legs 12 and the left and right rear legs 14 to move the stroller main body 10a forward and backward, and a pair of left and right handle pipes ( 18) One end of each arm rest 16 is pivotally mounted near the lower end of the handle pipe 18 on the left and right sides of the handle lever 15, and the left and right corners 12 of the other end of each arm rest 16 are pivotally mounted. Each top end of is pivotally mounted. Moreover, each top end of the left and right olfactory legs 14 is also pivotally attached to the middle part of each arm rest 16, and the bracket 19 bent in a "b" shape in the middle part of each olfactory leg 14 is shown. One end of the pivot is mounted. And the lower end part of each handle pipe 18 of the handle lever 15 is pivotally attached to the middle part of each bracket 19, and in the expanded state of the baby carriage 10, it was formed in the upper end part of the bracket 19. The lock member 20 pivotally mounted to the lower end part of each handle pipe 18 is couple | bonded with the part, and the expanded state is maintained.

On the other hand, the right and left full-length 12 is connected by the front connection bar 21, the foot rest 20a is installed, the left and right rear corners 14 are connected by the rear connection bar 22. A pair of left and right connecting bars 23 are respectively connected between the one leg 12 and one leg 14 and between the other leg 12 and the other leg 14, respectively. That is, the front end of each connecting bar 23 is pivotally mounted at the middle part of each full width 12, and the rear end of each connecting bar 23 is pivoted at the lower end of each handle pipe 18 together with the bracket 19. I am attached. Further, the middle portions of the left and right connecting bars 23 are connected to each other by stays 24 extending in the left and right directions.

And the pipe | tube cover attachment hole 31 for attaching the lid | cover 39 is attached to the handle pipe 18 of the left and right of the handle lever 15. As shown in FIG. Moreover, the basket 40 is attached to the left and right connection bars 23 which connect the left and right full-length 12 and the left and right back 14, respectively.

However, in the baby carriage main body 10a which has such a structure, the locking part 20 provided in the lower end part of each handle pipe 18 of the handle lever 15 is the coupling part formed in the upper end part of the bracket 19. As shown in FIG. By engaging in, the baby carriage 10 is maintained in a usable deployment state.

On the other hand, in this state, the above-mentioned locking member 20 and the bracket 19 are released | released by operating the operating device 25 provided with the knob lever 15. FIG. Thereby, the arm rest 16 and the connection bar 23 can be rocked upward with respect to each handle pipe 18 of the handle lever 15 centering around each pivot mounting point, (14) is rocked in a substantially parallel state. Thereby, the baby carriage 10 is folded small to be convenient to carry.

Here, in the stroller main body 10a, the handle lever 15, the front connecting bar 21, the rear connecting bar 22, and the stay 24 have two joints in each middle part in two same vertical planes. By 15a, 21a, 22a, 24a), it can be folded. For this reason, after folding so that the front leg 12 and the back leg 14 may be in parallel as mentioned above, when the handle pipe 18 of the left and right of the handle lever 15 is moved forward, the handle lever 15 and the front side The connecting bar 21, the rear connecting bar 22, and the stay 24 are folded in a "c" shape toward the front at the portions of the respective joints 15a, 21a, 22a, and 24a, thereby folding the stroller 10 in three steps. I can fold it small in a state.

By the way, in the baby carriage main body 10a comprised in this way, the seat 26 for carrying an infant is attached to the handle pipe 18 of the left and right of the handle lever 15, and the connecting bar 23 on the left and right. Specifically, both side portions of the back portion 26a of the infant seat 26 are mounted on the left and right handle pipes 18, and both side portions of the seat portion 26b are mounted on the left and right connecting bars 23, so-called hammocks. It is hanging in a state. In this state, the center portion of the lower surface of the seat portion 26b of the seat 26 is supported by the stay 24.

In general, in such a hammock-type baby carriage 10, since a plate-shaped core material is incorporated in the seat portion 26b of the seat 26, the seat portion 26b does not move in the left-right direction. It is stable. However, since the seat 26b of the seat 26 is supported by only one stay 24 extending in the left and right directions, the front part and the rear part of the seat part 26b are the stays 24. There is a problem in that the stability at both the front and the rear becomes extremely bad by rocking up and down around the center.

Therefore, conventionally, for example, as shown in FIG. 4, the support belt 27 is provided in the rear direction of the stay 24 from the left and right connecting bars 23 connected to the intermediate part in a taut manner. By supporting the seating portion 26b of the seat 26 by the support belt 27 and the stay 24, a baby carriage 10 'is proposed which prevents rocking of the seating portion 26b of the seat 26. have.

However, in such a conventional baby carriage 10 ', when the baby carriage main body 10a' is made into the three-stage folding state, as shown in FIG. 4 and FIG. 5, the seat | seat 24 and the front connection bar 21 make a seat | seat. Since the support belt 27 resists the movement (bending motion) of each part of the baby carriage main body 10a ', the 26 moves to the direction which pushes back, and the baby carriage main body 10a' is folded three steps. In order to make a state, a large operation force is required. In addition, although this problem can be solved once by setting the support belt 27 a little longer, in this case, the support of the seat part 26b of the seat 26 at the time of use of the baby carriage 10 is not enough. If the infant is taken, there is a problem that a large depression occurs at the rear of the seat portion 26b.

The first embodiment of the present invention has been devised in view of such a point, and as shown in FIG. The lower end portion 30 (see numeral 30a in FIG. 2) is sewn and attached. The upper end portions of these hawk-like belts 30 are firmly attached to the left and right handle pipes 18 of the handle lever 15, respectively, and the handle pipes 18 and the seat 26 of the handle lever 15 are fixed. A hawk-like belt 30 is provided tautly between the rear lower surface of the seat portion 26b.

However, in the baby carriage 10 shown in FIG. 1, at the time of use which expanded the baby carriage main body 10a, the sheet | seat 26 attached to the baby carriage main body 10a is similar to the left and right connection bar 23 at the same time. The center portion of the lower surface of the seat portion 26b is supported by the stay 24 extending in the left and right directions. In addition, the rear surface of the seat portion 26b of the seat 26 is suspended upward by left and right hawk-like belts 30, and the support portion 26b of the seat 26 is supported by the stay 24. The fluctuation can be effectively prevented.

On the other hand, in the case where the baby carriage main body 10a is folded in two stages for small folding, the left and right connecting bars 23 move upward with respect to the pivot mounting point with the left and right handle pipes 18 of the handle lever 15. As shown in FIG. 2, in the hawk-like belt 30, the distance between the attachment position to the seat portion 26b of the seat 26 and the attachment position to the handle pipe 18 is shortened, resulting in a hawk-like belt 30. ) Will loosen. Therefore, afterwards, when the stroller main body 10a is in a three-fold folding state, the hawk-like belt 30 does not resist the movement (three-fold folding operation) of each part, and makes the stroller main body 10a 'into a three-fold folding state. Can be easily performed.

&Lt; Embodiment 2 >

6 to 11, the hammock type baby carriage according to the second embodiment of the present invention will be described.

As shown in FIG. 6, the baby carriage 110 according to the second embodiment of the present invention is to suspend a seat for burning an infant from the baby carriage body, and a pair of left and right front legs on which the two-wheeled front wheel 111 is mounted ( 112, a pair of left and right legs 114 on which the rear wheels 113 of the two wheels are mounted, a handle lever 115 bent in a substantially inverted U shape, a pair of left and right arm rests 11 l, The detachable guide arm 119 which spans between each arm rest 116 is provided, and the baby carriage main body 110a is comprised by these members.

Here, the handle lever 115 is for transmitting a force to the left and right front legs 112 and the left and right back legs 114 to move the stroller body 110a forward and backward, and a pair of left and right handle pipes ( 117). In addition, connecting levers 118 are pivotally mounted at lower ends of the handle pipes 117 on the left and right sides of the handle lever 115 via brackets 152, and the front end of each of the connecting levers 118 is full-width 112. It is pivotally mounted. In addition, a basket 151 is attached to each connection lever 118.

In addition, the seat 120 is attached to the baby carriage main body 110a configured as described above. Here, the sheet 120 is comprised from the base sheet 120a and the detachable sheet 120b mounted on this base sheet 120a.

Among these, the base seat 120a is connected to the seat part 122, the backrest part 123 connected to the said seat part 122 so that relief is possible, and the upper edge part of this backrest part 123 so that a relief is possible. Has a headrest 124. Here, both side portions (not shown) of the seat portion 122 are mounted by the connecting lever 118, and both sides 121 of the backrest portion 123 and the headrest 124 are left and right of the handle lever 115 It is attached to the handle pipe 117, and the base sheet 120a is supported by the baby carriage main body 110a as a whole by this.                     

In such a hammock type stroller 110, it is necessary to change the inclination angles of the backrest 123 and the headrest 124. In this case, in order to protect the head of the infant burned on the seat 120, when the inclination angle of the backrest part 123 is reduced, the headrest 124 is raised against the backrest part 123. It needs to be in a state.

For this reason, conventionally, as shown in FIG. 9, the reclining angle change belt 128 which supports the backrest part 123 is tightened on the handle pipe 117 to the left and right of the handle lever 115, for example. It is proposed that the inclination angle of the backrest portion 123 can be changed by adjusting the length of the reclining angle changing belt 128.

Specifically, as shown in FIG. 9, a headrest support belt 125 is attached to the rear surface side of the headrest 124, and both ends of the headrest support belt 125 are provided with the backrest 123 and the headrest. Both sides 121 of 124 are fixed to the left and right handle pipes 117. On the other hand, as shown in FIG. 10, the tubular opening 126 sewn in the shape of a cylinder is formed in the back surface side of the back part 123, and these cylindrical openings 126 of the right and left are respectively The reclining angle changing belt 128 is fitted and connected. Further, at one end of each reclining angle changing belt 128, a buckle 127 is attached to a hook (not shown) fixed to the left and right handle pipes 117. A string 129 is attached to the other end of each reclining angle changing belt 128, and each of the strings 129 is pulled outward from the hole 130 formed in the center of the back surface side of the back portion 123, respectively. Next, the two straps 129 are tied to each other so that the length of the reclining angle changing belt 128 can be adjusted.

Here, in the initial state, each reclining angle changing belt 128 is supported by the reclining angle changing belt 128 in the initial state, and the backrest portion 123 is supported by the head. It is assumed that it is in the same plane as the support 124. In this state, the inclination angle (reclining angle) of the backrest part 123 can be changed by loosening the string 129 of each reclining angle change belt 128 and adjusting the length of both strings 129. At this time, when the inclination angle of the backrest portion 123 becomes small and the backrest portion 123 moves downward as a whole, the headrest 124 is suspended from the handle pipe 117 by the headrest support belt 125. As shown in FIG. 11, the headrest 124 is brought up with respect to the backrest portion 123, and functions as a protective plate to protect the head of the infant, which is burned by the seat 120.

However, in such a conventional baby carriage 110 ', the headrest support belt 125 and the reclining angle changing belt 128 change the inclination angle of the backrest portion 123 and at the same time the backrest portion 123. Although the headrest 124 can be raised with respect to the backrest part 123 according to the inclination angle of the backrest part, the reclining angle changing belt 128 with the buckle 127 has two points, and the reclining angle changing belt Two points of the string 129 connected to the 128 and the headrest support belt 125 for causing the headrest 124 to rise according to the inclination angle of the backrest portion 123 need to be five points in total. There is such a problem that a lot of articles to prepare these and sew on the backrest 123 and the headrest 124 of the sheet 120 (base sheet 120a) are required.

The second embodiment of the present invention is conceived in view of this point, and as shown in Fig. 6, the headrest support belt 131 and the reclining angle changing belt 132 are integrally formed.

That is, as shown in FIG. 6 and FIG. 7, the head restraint belt 131 is sewn and attached to the rear side of the head restraint 124 in a state where the head restraint support belt 131 is fitted. The headrest 124 is connected to the left and right handle pipes 117 through these two side portions 121 together with the backrest portion 123 of the seat 120 (base sheet 120a). Thereby, the headrest 124 is supported by the headrest support belt 131 with respect to the baby carriage main body 110a.

The headrest support belt 131 extends from side to side between the handle pipes 117 on the left and right sides of the handle lever 115 so as to cross the headrest 124, and is an extension portion extending both ends for reclining angle change. The belt 132 is formed. The reclining angle changing belt 132 is for supporting the backrest part 123 with respect to the baby carriage main body 110a, and the inclination angle of the backrest part 123 with respect to the baby carriage main body 110a by adjusting the length. You can change it.
