first implementation

First, a hammock-type stroller according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 5 .

As shown in FIG. 1 , the stroller 10 in the first embodiment of the present invention is a hammock-type stroller in which a seat for infants and young children is suspended on the main body of the stroller, and has a pair of left and right front legs equipped with double-wheeled front wheels 11. 12, a pair of rear feet 14 on the left and right of assembling the double-wheeled rear wheel 13, a hand push rod 15 bent into a nearly inverted U shape, a pair of arm frames 16 on the left and right, and a guardrail 17 hanging across each arm frame 16; by these The components constitute the stroller main body 10a.

In this embodiment, the hand push rod 15 is used to transmit power to the left and right front legs 12 and the left and right rear legs 14 to move the main body of the stroller 10a forward and backward, and has a pair of left and right handle pipes 18 . Near the left and right handle pipes 18 lower ends of the hand push rod 15, an end of each arm frame 16 is connected with a pivot respectively, and the other end of each arm frame 16 links to each other with each top of the left and right front feet 12 with a pivot. In addition, each top end of the left and right rear legs 14 is also connected to the middle part of each arm frame 16 with a pivot, and one end of a bracket 19 bent into a [く] shape is connected with a pivot at the middle part of each rear leg 14. And, the middle part of each bracket 19 is connected with each handle tube 18 lower ends of the hand push rod 15 with a pivot respectively, and under the unfolded state of the stroller 10, the mating part formed at the upper end of the bracket 19 can be connected to each handle. This unfolded state can be maintained by cooperating with the locking member 20 connected to the sliding pivot at the lower end of the tube 18 .

On the other hand, the left and right front legs 12 are connected by a front link 21 provided with a foot pad 20 a, and the left and right rear legs 14 are connected by a rear link 22 . Moreover, between the one front leg 12 and the one rear leg 14 and between the other front leg 12 and the other rear leg 14 are respectively connected by a pair of left and right links 23 . That is, the front ends of each connecting rod 23 are pivotally connected to the middle part of each front foot 12, and the rear ends of each connecting rod 23 are connected to the lower end of each handle tube 18 with a pivot together with the bracket 19. In addition, the middle portions of the left and right links 23 are connected to each other with a stay 24 extending in the left and right directions.

In addition, on the left and right handle pipes 18 of the hand push rod 15, a tubular canopy fitting 31 for assembling a canopy 39 is mounted. A frame basket 40 is also installed on the left and right connecting rods 23 connecting the left and right front feet 12 and the left and right rear feet 14 respectively.

In addition, in the stroller main body 10a constructed in this way, the locking member 20 provided at the lower end of each handle tube 18 of the push rod 15 can hold the stroller 10 in a fixed position by cooperating with the matching portion formed at the upper end of the bracket 19. Available expanded states.

On the other hand, in this state, the cooperation between the locking member 20 and the bracket 19 can be released by operating the operating device 25 provided on the push rod 15 . Like this, arm frame 16 and connecting rod 23 just can be centered on each handle tube 18 of relative hand push rod 15 upwards with each pivot point, and front foot 12 and rear foot 14 swing into nearly parallel state. In this way, the stroller 10 is folded for portability.

In this embodiment, for the stroller 10a, the hand push rod 15, the front link 21, the rear link 22 and the strut 24 can use joints at two positions in the middle of the two same vertical planes. 15a, 21a, 22a, 24a are folded. Therefore, after the above-mentioned front feet 12 and rear feet 14 are folded in parallel, once the left and right handle tubes 18 of the hand push rod 15 are moved to the front, the hand push rod 15, the front connecting rod 21, the rear connecting rod 22 and the strut 24 can be moved to the front. The position of each joint 15a, 21a, 22a, 24a is folded forward into a 〖コ〗 shape, and the stroller 10 can be folded into a three-fold state.

However, in the stroller main body 10a constructed in this way, the seat 26 for an infant is attached to the left and right handle pipes 18 and the left and right links 23 of the hand push rod 15 . Specifically, both sides of the backrest 26a of the infant seat 26 are attached to the left and right handle pipes 18, and both sides of the seat 26b are attached to the left and right links 23, and are suspended in a so-called suspended state. In addition, in this state, the seat portion 26b of the seat 26 is supported by the stay 24 at the central portion of the lower surface thereof.

In general, in such a hammock stroller 10, since the seat portion 26b of the seat 26 contains a sheet-shaped core material, the seat portion 26b is stable and does not move in the left-right direction. However, because the seat portion 26b of the seat 26 is only supported by a stretched strut 24 in the left-right direction, the front and rear portions of the seat 26b can swing up and down with the strut 24 as the center. Stability in the rear is extremely poor.

Therefore, in the prior art, as shown in FIG. 4 , a baby carriage 10 ′ is proposed. In the left and right connecting rods 23 connected with the struts 24 in the middle, a support belt 27 is also provided behind the struts 24 . The seat part 26b of the seat 26 is supported by the support belt 27 and the stay bar 24, so that the seat part 26b of the seat 26 can be prevented from swinging.

However, for the stroller 10' in this prior art, when the stroller main body 10a' is folded in three, as shown in FIGS. The seat 26 is moved to the rear, and the support belt 27 blocks the movement (bending action) of the parts of the stroller body 10a', so there is a problem that a large operating force is required to turn the stroller body 10a' into a three-fold state. . In addition, although this problem may be solved by setting the length of the support belt 27, in this case, there is a problem that the seat portion 26b of the seat 26 cannot be reliably supported when the stroller 10 is in use. The rear sinks more, etc.

The first kind of embodiment of the present invention is researched and developed after considering these problems, as shown in Figure 1, sews the lower end of two suspenders (left and right pair of straps) 30 on the rear portion below the seat portion 26b of seat 26 (referring to figure Reference number 30a) in 2. And each suspender 30 upper ends are respectively fixed on the left and right handle pipes 18 of hand push rod 15, and suspender 30 is arranged between each handle pipe 18 of hand push rod 15 and the seat portion 26b rear portion below of seat 26.

In addition, for the stroller 10 shown in Fig. 1, when the stroller main body 10a is expanded for use, the seat 26 assembled with the stroller 10a is suspended on the left and right connecting rods 23, and at the same time, the central part of the seat 26b under the seat is moved from the left and right directions. Extended strut 24 supports. And, the seat portion 26b lower rear portion of seat 26 is hoisted to the top with sling 30, and the support of strut 24 can effectively prevent the swing of seat 26 seat portion 26b by assisting each other.

On the other hand, when the baby carriage 10a is to be folded into a half-folded state, since the left and right connecting rods 23 are centered on the pivot points of the left and right handle tubes 18 of the hand push rod 15 to move upward, as shown in FIG. , for the strap 30, the distance between the position where it is attached to the seat portion 26b of the seat 26 and the position where it is attached to the handle pipe 18 becomes shorter, and as a result, the strap 30 becomes loose. Therefore, when the baby carriage main body 10a is in the three-fold state, the strap 30 does not block the movement of the components (three-fold operation), and the operation of turning the baby carriage main body 10a' into the three-fold state can be easily performed.

Second implementation

Next, a hammock-type stroller according to a second embodiment of the present invention will be described with reference to FIGS. 6 to 11 .

As shown in FIG. 6 , the stroller 110 in the second embodiment of the present invention is a hammock-type stroller in which an infant seat is suspended on the main body of the stroller. A pair of front feet 112, a pair of left and right rear feet 114 assembled with double-wheeled rear wheels 113, a hand push rod 115 bent into a nearly inverted U shape, a pair of left and right arm frames 116, and guardrails 119 hung between each arm frame 116; The baby carriage main body 110a is comprised by these components.

In this embodiment, the hand push rod 115 is used to transmit power to the left and right front legs 112 and the left and right rear legs 114 to move the main body of the stroller 110a forward and backward, and has a pair of left and right handle pipes 117 . The lower ends of the left and right handle tubes 117 of the hand push rod 115 are pivotally connected to the connecting rods 118 through respective brackets 152 , and the front ends of the connecting rods 118 are pivotally connected to the front feet 112 . In addition, a basket 151 is attached to each link 118 .

The seat 120 is mounted on the stroller main body 110a constituted in this way. In this embodiment, the seat 120 is composed of a base 120a and a detachable seat 120b placed on the base 120a.

Wherein, the base 120 a has a seat portion 122 , a back corresponding portion 123 connected to the seat portion 122 and undulating, and a head rest 124 connected to the upper edge of the back corresponding portion 123 and capable of undulating. In this embodiment, the two sides (not shown) of the seat portion 122 are installed on the connecting rod 118, and the two sides 121 of the back corresponding portion 123 and the head rest 124 are installed on the left and right handle tubes 117 of the hand push rod 115. , so that the base 120a is supported by the stroller body 110a as a whole.

Such a hammock stroller 110 must be able to change the inclination angles of the back corresponding portion 123 and the headrest 124 . And, in this case, in order to protect the head of an infant sitting on the seat 120, the inclination angle of the back corresponding portion 123 is reduced, and the head rest 124 of the back corresponding portion 123 must become able to rise. state.

Therefore, taking the type proposed in the prior art as an example, as shown in FIG. 9 , on the left and right handle pipes 117 of the hand push rod 115, the belt 128 for changing the inclination angle of the supporting back corresponding part 123 is set, and the belt 128 for changing the inclination angle is adjusted by adjusting the belt 128 for changing the inclination angle. The length of the belt 128 can change the inclination angle of the back corresponding portion 123 .

Specifically, as shown in FIG. 9 , a headrest support belt 125 is installed on the inner side of the headrest 124, and the two ends of the headrest support belt 125 are connected with the back corresponding part 123 and the two side parts 121 of the headrest 124 together. Be fixed on the left and right handle tubes 117. On the other hand, as shown in FIG. 10 , a cylindrical opening 126 sewn into a cylindrical shape is formed at the left and right parts on the back side of the back corresponding portion 123 , and left and right angles of inclination are respectively inserted into the left and right cylindrical openings 126 . Change belt 128 . Wherein, the buckle 127 that cooperates with the hook (not shown) fixed on the left and right handle pipes 117 is installed on one end of each inclination angle changing belt 128 . And, the other end of belt 128 is sewed with soft rope 129 at each inclination angle change, and each soft rope 129 is drawn to the outside respectively from the cavity 130 that the inner side central part of back corresponding part 123 forms, and both sides are drawn on the top. The flexible cord 129 tied together can adjust the length of the belt 128 for changing the inclination angle.

In this embodiment, the initial state of each inclination angle changing belt 128 is shown in FIG. In this state, the inclination angle (inclination angle) of the back corresponding part 123 can be changed by loosening the cords 129 of the inclination angle changing belts 128 and adjusting the lengths of both cords 129 . At this time, once the inclination angle of the back corresponding part 123 becomes smaller, the back corresponding part 123 moves downward as a whole, because the head rest 124 is hung on the handle pipe 117 by the head support support belt 125, so, as shown in FIG. 11 , the head rest 124 The opposite back corresponding portion 123 becomes the rising state, has the function as a protective plate, and protects the head of a sleeping infant sitting on the seat 120 .

However, in this type of prior art stroller 110', since the inclination angle of the back corresponding portion 123 is changed by using the headrest support belt 125 and the inclination angle changing belt 128, at the same time, the inclination angle of the back corresponding portion 123 is adjusted accordingly. The headrest 124 also can be raised relative to the back corresponding part 123, and it is necessary to have two points on the belt 128 for changing the angle of inclination of the installation buckle 127, and two points for connecting the soft rope 129 to the belt 128 for changing the angle of inclination. Points and corresponding to the angle of inclination of the back corresponding portion 123 make the headrest support belt 125 which raises the headrest 124 a point totaling five points, which are sewn onto the back corresponding portion 123 and the headrest 124 of the seat 120 (base 120a). It takes time to wait.

The second embodiment of the present invention was developed in consideration of these problems, and as shown in FIG. 6 , a headrest support belt 131 and a belt 132 for changing an inclination angle are integrally formed.

That is, as shown in FIGS. 6 and 7 , the headrest support belt 131 is sewn into an inserted shape on the inner side of the headrest 124, and the headrest 124 and the back corresponding portion 123 of the seat 120 (base 120a) are connected by the headrest support belt 131. Utilize its two sides 121 to be connected on the left and right handle tubes 117 together. Thus, the headrest 124 is supported against the stroller stroller body 110 a by the headrest support strap 131 .

The headrest support belt 131 extends left and right between the left and right handle pipes 117 of the push rod 115 so as to pass through the headrest 124 , and an inclination angle changing belt 132 is formed as an extension extending to both ends. The inclination angle changing belt 132 supports the back corresponding part 123 with respect to the stroller main body 110a, and the inclination angle of the back corresponding part 123 with respect to the stroller main body 110a can be changed by adjusting its length. In addition, a tilt changing mechanism is constituted by the headrest supporting belt 131 and the tilt angle changing belt 132 , and the tilt angle of the back corresponding part 123 and the headrest 124 is changed.

In this embodiment, the inclination angle changing belt 132 has a pair of left and right belt parts 132a as shown in FIG. 7 . Each belt portion 132a of the inclination angle changing belt 132 extends in a manner to intersect with a part of the headrest support belt 131, and is inserted into the cylindrical opening 126 provided on the left and right sides of the back corresponding portion 123, and the left and right ends are sewn together. The cord 133 is pulled out from the hole 130 formed in the center of the inner side of the back corresponding portion 123 in each cylindrical opening portion 126 .

On the flexible ropes 133 on both sides, the adjusting parts 134 for adjusting the length of the flexible ropes 133 are installed. Once the length of the flexible ropes 133 is adjusted by the adjusting parts 134, the length of the inclination angle changing belt 132 is shortened, as shown in FIG. The upper portion of the corresponding portion 123 is lifted up by the belt 132 for changing the inclination angle, and its state can be changed so that the inclination angle becomes larger. In this way, the back corresponding part 123 becomes the raised state, and the back corresponding part 123 and the head rest 124 are in a state of nearly the same plane.

On the other hand, once the length of the flexible cord 133 is adjusted by the adjustment member 134 and the length of the inclination angle is changed with the belt 132, as shown in Figure 8, the back corresponding part 123 falls to the rear, and the inclination angle becomes smaller and can be changed. its status.
