Detailed ways

The preferred embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the utility model can be more easily understood by those skilled in the art. The orientation words such as front and back, up and down, left and right mentioned in the utility model are all defined with the specific orientation where the chair frame is in the unfolded position when the children's dining chair of the utility model is in use.

Figures 1 to 4 show a foldable children's dining chair. As shown in FIG. 1 to FIG. 4 , the children's dining chair of the present invention includes a chair frame 1 having an unfolded position and a folded position, and a locking mechanism for locking the chair frame 1 in the unfolded position.

As shown in FIG. 1 , when the chair frame 1 is in the deployed position, the chair frame 1 includes: a backrest bar 11 ; an armrest 12 ; a rear bracket 14 ; a front bracket 15 ; and a seat post 17 . The armrest 12 is substantially U-shaped, and includes two side armrests 121 extending in the front-rear direction, and a front armrest 122 connected to the front ends of the side armrests 121 extending in the left-right direction. The backrest bar 11 is roughly in an inverted U shape, and the rear ends of the two side armrests 121 are rotatably connected to the left and right sides of the backrest bar 11 through the first pivot 31 . The rear bracket 14 is generally frame-shaped, and has a horizontal section 141 extending in the left-right direction on the upper part. The horizontal section 141 and the front armrest 122 are rotatably mounted on a rotating member 13 . The front bracket 15 is roughly U-shaped, and the two upper ends of the front bracket 15 are respectively connected to the left and right sides of the rear bracket 14 through the fifth pivot 35 rotatably connected. There are two seat bars 17, and a slider 16 is sheathed on the left and right sides of the front bracket 15 respectively. The slider 16 can slide along the extension direction of the front bracket 15. The member 16 is rotatably connected by a fourth pivot 34 . The rear ends of the two seat rods 17 are rotatably connected with the two lower ends of the backrest rod 11 through the second pivot 32 respectively, and the two seat rods 17 are also rotated with the left and right sides of the rear bracket 14 through the third pivot 33 connection, wherein the third pivot 33 is located between the second pivot 32 and the fourth pivot 34, the fifth pivot 35 is set higher than the third pivot 33, and the first pivot 31 is higher than the second pivot 32 set up.

In this embodiment, the seat post 17 and the front bracket 15 are slidably and rotatably connected through the sliding member 16 and the fourth pivot 34 . In other embodiments, the front bracket 15 and the seat post 17 can also be directly connected, such as: a chute is provided on the front support 15, and a protrusion is provided on the seat post 17, and the protrusion is slidably and rotatably inserted in the sliding slot. in the slot.

The first pivot 31 , the second pivot 32 , the third pivot 33 , the fourth pivot 34 and the fifth pivot 35 are horizontally arranged and extend along the left-right direction. This makes the parts of the chair frame 1 close together to the greatest extent after the chair frame 1 is folded, so that the volume of the folded children's dining chair is smaller.

The locking mechanism is arranged on the sliding part 16 and the front bracket 15, and the locking mechanism adopts a locking structure widely used in children's dining chairs in the prior art, such as the cooperation of the lock pin and the locking groove, that is, one of the sliding part 16 and the front bracket 15 A lock slot is provided on the top, and a lock pin is established on the other. When the lock pin is inserted in the lock slot, the slider 16 and the front bracket 15 are locked. When the lock pin breaks away from the lock slot, the slider 16 and the front bracket 15 are unlocked.

The high chair also includes an unlocking mechanism 2 for unlocking the locking mechanism. The unlocking mechanism 2 includes a first unlocking member 21 slidably arranged on the seat post 17, a second unlocking member 22 rotatably arranged at the rear of the seat post 17, and a second unlocking member 22 connected to the second unlocking member 22 for driving the first unlocking member. The flexible operation belt 23 that the two unlocking parts 22 rotate. The second unlocking part 22 and the first unlocking part 21 cooperate to drive the first unlocking part 21 to slide through the slope, that is, the second unlocking part 22 has an unlocking slope, and the first unlocking part 21 has a matching slope matching with the unlocking slope, and the unlocking slope When the second unlocking part 22 is in tight contact with the matching slope, the first unlocking part 21 slides under the cooperation of the two slopes. The first unlocking member 21 is connected with the lock pin of the locking mechanism through a pulling cable to unlock the locking mechanism. The operation belt 23 is a polypropylene belt, and the two ends of the polypropylene belt are fixedly connected to the two second unlocking parts 22 respectively, and the two sliding parts 16 can be unlocked by pulling the polypropylene belt upwards.

The chair frame 1 also includes a foot rod 18 bent and extended downward from the front end of the seat rod 17 , and a foot pedal 19 arranged at the lower end of the foot rod 18 and extending along the left-right direction.

As shown in Figure 1 and Figure 2, when the children's dining chair is in the unfolded position, a stable triangular structure is formed between the rear bracket 14, the front bracket 15 and the seat rod 17, and the backrest rod 11, the side armrest 121, the rear bracket 14 and the seat rod 17 form a stable triangular structure. A quadrilateral structure is formed between the rods 17 .

As shown in FIG. 3 , when the chair frame 1 is folded, the operating belt 23 is pulled upwards, the second operating member 22 rotates, and the first operating member 21 slides under the action of the inclined surface, so that the traction cable drives the lock of the locking mechanism. The pin breaks away from the lock groove, that is, the locking mechanism is unlocked, and the slider 16 slides down along the front bracket 15 under the action of gravity so that the front portion of the seat rod 17 turns downward. Under the action of the seat rod 17, the front bracket 15 leans against the rear bracket 14, and , the rear part of the seat bar 17 is turned upwards by the pulling force of the operating belt 23, the backrest bar 11 is turned down and leans against the rear bracket 14, and the side armrest 121 leans against the rear bracket 14, which is easy to fold and realizes the carrying of the children's dining chair. That's right.

As shown in Figure 4, when the chair frame 1 is in the folded position, the front bracket 15, the rear bracket 14, the seat post 17, the back bar 11, and the side armrests 121 are all folded together, and the volume of the folded children's dining chair is relatively small , and can stand on its own after being folded for easy storage.

The above-mentioned embodiment is only to illustrate the technical conception and characteristics of the present utility model. It is a preferred embodiment. Protection scope of utility model. All equivalent transformations or modifications made according to the spirit of the present utility model shall fall within the protection scope of the present utility model.
