Foldable high chair skeleton

Collapsible high chair frame

This creation is about a collapsible high chair frame, which is controlled by a positioning device, and the seat is folded synchronously through the linkage group when released.

The high chair system provides children to dine. For the current general high chair structure, please refer to US Patent No. 5,435, 620, Patent No. 4,958, 885, Patent No. 5,509, 719, Patent Case No. 5, 348, 374, Patent Case No. 5, 507, 550, Patent Case No. 5, 806, 922, Patent Case No. 5, 829, 826, Patent Case No. 5, 927, 805, Patent Case No. 5, Patent content such as 951, 102 patent case, No. 6, 010, 184, etc. The so-called high chair structure is divided into two parts: the seat and the legs. The legs of the chair can be supported on the ground, and a children's dinner plate is usually attached.

There are many common types of high chair legs, such as the fixed legs disclosed in Patent Nos. 5, 806, and 922 and Patent Nos. 5, 927, and 805; another example is No. 5, 507, Patent No. 550 and Patent No. 5, 951, and 102 disclosed that the two legs of the chair are connected at the same position, and the bottom end is expanded at an angle for support on the ground; as in No. 5, 509 , Patent No. 719, Patent No. 5, 435, 620, and Patent No. 4, 958, 885 disclose a tilting chair leg, which includes a first leg lying horizontally on the ground. And there is a second chair leg connected to one end of the first chair leg and at an inclined angle with the first chair leg. The tilting chair legs can also be divided into fixed type (Patent No. 5, 509, 719), modular type (Patent No. 5, 435, 620) and foldable type (Patent No. 4, 958, 885) Among them, the fixed type cannot be folded and occupies a considerable volume when storing. The combined type can separate the components when storing, but it is not convenient to assemble and disassemble. The foldable type can directly connect the first leg of the chair. The second chair legs are close together, and the folding action is relatively simple and convenient. However, the folding mechanism of Patent Nos. 4, 958, and 885 is too complicated.

In view of this, the main purpose of this creation is to provide a collapsible high chair frame.

According to the collapsible high chair frame disclosed in this creation, it may contain collapsible support frame, seat, connecting rod group and positioning mechanism. The folding support frame includes a front bracket, a rear bracket and a pivot seat that can be connected to each other. A pivoting seat is used to connect the upper ends of the front support and the rear support. Once the folding support frame is folded, the front support and the rear support can be pivoted to move closer to each other. In addition, the seat can be composed of a seat part and a backrest pivotally connected to each other. The seat is connected to the collapsible support frame through the link group, so that the collapsible frame can be synchronized to fold the seat through the link group by controlling the positioning device between the collapsible support frame and the seat , So that a small volume, collapsible high chair frame is formed.

In order to make the above and other purposes, features, and advantages of this creation more obvious and easy to understand, a preferred embodiment is specifically cited below, in conjunction with the accompanying drawings, for detailed description:

Please refer to the picture shown in Figure 1. This creation system can be implemented as a collapsible high chair frame 1, providing a collapsible, small size and easy to store frame. It includes a folding support frame 2, a seat 3, a connecting rod group 5 and a positioning mechanism 6.

The folding support frame 2 is composed of a front bracket 21, a rear bracket 22, and a pivot seat 23, and the front and rear brackets 21, 22 are slightly U-shaped. In this embodiment, the pivot seat 23 is connected to The upper ends of the front and rear brackets 21, 22 are connected to the upper end of the front bracket 21 with a connecting piece 24 (as shown in Figure 3), and the upper end of the rear bracket 22 is pivotally connected by the connecting piece 24 (the upper end of the rear bracket 22 can also be made The upper end of the rear bracket 22 is directly pivotally connected to the pivot seat 23). When the present invention is unfolded, the front bracket 21 and the rear bracket 22 rotate according to the pivot joint to form a support frame 2, whereby the seat 3 is suspended and retracted. When folded, the front bracket 21 and the rear bracket 22 also rotate and close together according to the pivot point; and the front end of the pivot seat 23 is connected with a dinner plate 4 whose front and rear positions can be adjusted.

The seat 3 includes a seat portion 31 and a backrest portion 32 (please refer to the figure shown in Figure 2). The seat portion 31 and the backrest portion 32 are pivotally connected to each other, and the seat portion 31 of the seat 3 is pivotally connected to the front bracket 21, And when the frame of the seat 3 is unfolded, the seat portion 31 and the backrest portion 32 form approximately ninety degrees or greater than ninety degrees, so as to provide seating for infants and children, and when the frame 1 is folded, the seat The portion 31 and the backrest portion 32 are folded at an angle less than ninety degrees. The backrest 32 is provided with a catch 33.

The connecting rod group 5 is pivotally connected between the seat 3 and the folding support frame 2, and may include a first connecting rod 51 and a second connecting rod 52, wherein the first connecting rod 51 is pivotally connected to the seat portion 31 of the seat 3 and the rear The second connecting rod 52 is pivotally connected between the backrest 32 and the first connecting rod 51. When folded, the rear support 22 moves toward the front support 21, and the first and second The connecting rods 51 and 52 link the seat portion 31 and the backrest portion 32 of the seat 3 so as to be folded into a state where the included angle is less than ninety degrees.

The positioning mechanism 6 (please refer to the figure shown in Fig. 4) is attached to the pivot seat 23 to be clamped and fixed to the seat 3. It includes a button 61, a driving block 62, a latch 63 and an elastic element 64. When the high chair frame 1 is unfolded, the latch 63 protrudes from the pivot seat 23 by the elasticity of the elastic element 64, and is connected to the latch 33 provided on the back 23 of the seat 3 It forms a locking and fixing, so that the whole high chair frame 1 cannot be rotated and fixed. When the frame 1 is to be folded, the button 61 is pressed, and the relative slope 621, 631 is configured to make the latch 63 move toward the pivot seat 23 to disengage from the latch 33, so that the high chair frame 1 can be folded (as shown in Figure 5), and the rear bracket 22 When the forward bracket 21 is moved closer, the backrest 32 and the seat portion 31 of the seat 3 are simultaneously folded through the linkage group 5 to form a smaller storage or transport volume (as shown in Figure 6).

The above are only the preferred embodiments of this creation, and are not used to limit the scope of implementation of this creation; that is, all equal changes and modifications made in accordance with the scope of the patent application for this creation are covered by the scope of this creation patent .
