Detailed ways

The folding high chair skeleton 1 shown in Figure 1 at least includes a rear foot frame 2, a backrest frame 3, a front foot frame 4, an armrest frame 5, a seat frame 6, a first connecting rod 7 and a locking mechanism 8 . Wherein, the front leg frame 4 is provided with a first pivot point 41 pivotally connected with the rear leg frame 2, a second pivot point 42 pivotally connected with the backrest frame 3, and the lockable position 43 is engaged with the backrest frame 3 to generate a locking effect, so that The foldable high chair frame 1 can be locked in a stretched state 11 for use. Preferably, for the convenience of assembly, a first pivot ear 44 can be provided on the front leg frame 4 to provide the aforementioned second pivot point 42 to pivotally connect with the backrest frame 3 .

The rear end of the armrest frame 5 is pivotally connected with the backrest frame 3, a front pivot point 61 and a rear pivot point 62 are provided on the seat frame 6, and a first lower pivot point 71 and a rear foot frame are provided on the first connecting rod 7. 2 pivot connection, the second lower pivot point 72 is pivotally connected to the front pivot point 61 of the seat frame 6, and the upper pivot point 73 is pivotally connected to the armrest frame 5.

The locking mechanism 8 is installed on the back frame 3 in an operative manner, releasably engaged with the lockable part 43 of the front foot frame 4, and the back frame 3 cannot pivot relative to the front foot frame 4 by the locking mechanism. Thereby the retractable high chair frame 1 is locked in a used state 11; The leg dining chair frame 1 can be converted into a folded state 12 .

The rear foot frame 2 of the present utility model, the front foot frame 4 and the backrest frame 3 can be welded with metal strips and sheets, and plastics are integrally formed or processed with bending equipment to make a U-shaped metal pipe as shown in Figure 1. Since the front foot frame 4 and the rear foot frame 2 occupy a relatively large proportion below the first pivot point 41, if the opening angle is too large, it is easy to deform; preferably, the implementer may consider pivoting between the front foot frame 4 and the rear foot frame 2 A connecting rod group 9 is established to limit the maximum angle at which the front foot frame 4 and the rear foot frame 2 open. The connecting rod group 9 of this embodiment can be composed of a pair of lever arms pivotally connected. They are in a straight line with each other when they are opened, and can be pivoted and folded in half when they are folded. When being in a straight line, the maximum angle at which the front foot frame 4 and the rear foot frame 2 can be limited can be limited.

As shown in Figures 2-4, for the convenience of assembly, preferably a second pivot ear 31 can be provided on the back frame 3 to pivotally connect with the rear end of the armrest frame 5, and a dinner plate 51 can be mounted on the armrest frame 5 .

The foot pad can prevent the baby's feet from hanging in the air and increase the sense of security. However, the high chairs generally available on the market are usually not equipped with the foot pad, but the foldable high chair frame 1 of the utility model can be selected to pivot. Establish a pedal frame 64. As shown in Figure 2, the foldable high chair skeleton 1 of the present embodiment includes a pedal frame 64 and a second connecting rod 52, the pedal frame 64 is pivotally connected to the front end of the seat frame 6, the second The connecting rod 52 is pivotally connected between the front end of the armrest frame 5 and the pedal frame 64 to produce a linkage effect. In addition, if a dinner plate 51 is mounted on the armrest frame 5 during implementation, the second connecting rod 52 can optionally be pivotally connected between the meal plate 51 and the pedal frame 64 to produce the same linkage folding effect.

Preferably, the locking mechanism 8 of the present utility model can be implemented as a spring-biased sliding sleeve 81, so that the spring-biased sliding sleeve 81 can slide along the backrest frame 3 and enclose the lockable locking mechanism of the front foot frame 4. The position 43, so that the back frame 3 cannot pivot relative to the front leg frame 4. Specifically, a long slotted hole 32 and a pin 33 can be set on the back frame 3, and the pin 33 can be used to pass through the spring-biased sliding sleeve 81 and the long slotted hole 32, so that the spring-biased sliding sleeve 81 can Sliding along the back frame 3 under the limitation of the slotted hole 32.

The spring-biased sliding sleeve 81 is provided with a concave portion 35 for covering the top of the front leg 4 , so as to generate a locking effect that prevents the backrest 3 from pivoting relative to the front leg 4 . In order to facilitate the user to pull the spring-biased sliding sleeve 81, a finger hole 34 can be set on the spring-biased sliding sleeve 81 for the user's fingers to pass through to facilitate the pulling operation, thereby releasing the lock. The locking state of mechanism 8.

As shown in Figure 3, when folding the folding high chair frame 1 of the present invention, the user only needs to release the locking state of the locking mechanism 8, for example, pull upward the sliding sleeve 81 biased by the spring of this embodiment. , and then the backrest frame 3 is pushed forward, and the dinner plate 51, the pedal frame 64, the front foot frame 4 and the rear foot frame 2 can be folded together to the folded state 12 as shown in Figure 4 .
