Detailed ways

The technical solutions of the present invention will be further elaborated below with reference to the accompanying drawings and specific embodiments.

Referring to the multifunctional children's chair shown in FIGS. 1 to 7 , it includes a base 10 for being supported on a support plane and a seat assembly 20 disposed on the base 10, the base 10 includes a front support seat extending in the front-rear direction 1 , and a rear support base 2 rotatably connected to the front support base 1 , and the lower part of the front support arm 3 is fixed on the front of the front support base 1 . The rear support seat 2 has a rotating end and a supporting end respectively arranged at two different ends in its own length direction. The child chair has a first use state and a second use state. When the child chair is in the first use state, please refer to FIG. 1 and FIG. 2, the rear support seat 2 extends in the front-rear direction and is supported on the support plane together with the front support seat 1; when the child chair is in the second state of use, the front support seat 1 and the rear support seat 2 are respectively converted to the vertical direction. In extension, the rotating end of the rear support seat 2 is on the top and the support end is on the bottom, and the support end of the rear support seat 2 and the front end of the front support seat 1 are jointly supported on the support plane.

Specifically, in this embodiment, the seat assembly 20 includes a seat pocket frame 4, and a support arm 3 fixedly connected between the front part of the base 10 and the seat pocket frame 4, and the support arm 3 is gradually inclined upward from front to back Extendingly arranged, the lower part of the support arm 3 is fixed on the front part of the front support base 1 .

An angle α is formed between the length extension direction of the seat pocket frame 4 and the horizontal plane. When the child chair is converted from the first working state to the second working state, the rear part of the front support seat 1 is raised and the front part is supported on the ground , the angle of the seat assembly 20 on the seat assembly 20 is changed accordingly, so that the above-mentioned included angle α increases, so that the child can be supported in the seat assembly 20 in different postures.

Further, as shown in the drawings, the seat assembly 20 further includes a seat frame 5 provided on the seat pocket frame 4, the seat frame 5 extending in the front-rear direction, the front portion of which is fixedly connected to the seat pocket frame 4, the seat frame 5 The front end of 5 is higher than the rear end, and an angle β is formed between the length extension direction of the seat frame 5 and the horizontal plane. When the child chair is converted from the first working state to the second working state, the above-mentioned angle β decreases, so that the two In the working state, the child obtains various sitting and reclining supports on the seat assembly 20 .

Specifically, as shown in the drawings, the rear support seat 2 is rotatably connected to the rear of the front support seat 1. When the child chair is in the second use state, the rear support seat 2 rotates relative to the front support seat 1, so that the rear support seat 2 is rotated relative to the front support seat 1.

The front cross bar 12, here, the above-mentioned front support bar 11 is an arc bar. The support arm 3 has two groups which are respectively arranged on the left and right sides. Each support arm 3 is fixed on the front end of the front support rod 11 on the same side. Here, the support arm 3 on the same side is integrated with the front support rod 11. an integral part. The seat pocket surrounding frame 4 is in a closed shape along the circumferential direction, and has surrounding frame rods disposed on the left and right sides and extending obliquely in the up-down direction. Each surrounding frame rod is fixedly installed on the support arm 3 on the same side.

The rear support base 2 has two groups of rear support rods 21 respectively arranged on the left and right sides, and a plurality of rear cross rods 22 fixed between the rear support rods 21 on both sides. Here, the rear support rods 21 are also arc rods. One end of the rear support rod 21 is rotatably connected to the rear end of the front support rod 11 on the same side. When the child chair is in the second use state, the other end of the rear support rod 21 is supported on the support plane.

On the left and right sides of the child chair, between the rear support bar 21 and the front support bar 11 are also provided a locking assembly for locking the two relative to each other, and an unlocking member 9 for unlocking the locking assembly. The two unlocking members 9 is located between the two sets of rear support bars 21 in the left-right direction. Referring to FIG. 3 , the locking assembly specifically includes a first connecting head 14 disposed at the rear end of the front support rod 11 , and a second connecting head 24 disposed at the front end of the rear support rod 21 . The first connecting head 14 and the second connecting head 24 wrap around The shaft 6 is rotatably connected. The first connecting head 14 has a plurality of first tooth grooves distributed at intervals along the circumferential direction, the second connecting head 24 has a plurality of second tooth grooves distributed at intervals along the circumferential direction, and the locking assembly further includes a shaft capable of being along the axial direction of the rotating shaft 6 . The locking slider 7 is relatively slidably arranged between the first connecting head 14 and the second connecting head 24, and the elastic member 8 provides the locking slider 7 away from the first connecting head 14, and the locking slider 7 has a circumferential interval There are a plurality of distributed locking teeth, and the unlocking member 9 is slidably arranged on the inner side of the second connecting head 24 . When both ends of the locking teeth are located in the first tooth slot and the second tooth slot at the same time, the locking assembly is locked; when the unlocking member 9 is driven to slide to push the locking slider 7 away from the second connecting head 24, the locking tooth is removed from the first tooth slot. The second tooth slot is disengaged and only located in the first tooth slot, the locking assembly is unlocked, and the rear support rod 21 can rotate relative to the front support rod 11 at this time.

To sum up, the multifunctional children's chair of the present embodiment can be used as a rocking chair by being supported on the ground in a first state of use, and can be stably supported on the ground and used as a toddler chair in the second state of use. In the second state of use, it can also be used as a children's high chair by being fixed to an adult's seat through a connecting piece.
