Description

Linked collapsible high chair

Technical field:

The invention relates to the technical field of high chairs, in particular to an interlocking foldable high chair.

Background technique:

Parents use different products to assist with feeding from infancy to when a child is old enough to sit securely at a table. One such product is a high chair, which is often used to move infants and toddlers Supported in an elevated position so that the caregiver can easily feed the child, the high chair is a free standing unit that provides a safe and stable seating area with a feeding tray that lifts from its height The foot chair is removed to allow easy placement of the child in the high chair, as well as easy cleaning of the feeding tray and high chair structure.

The dining plate, the seat board, the back board, the pedals, the front chair pins and the rear chair pins of the existing high chair, the pedals are arranged under the seat board, and the overall structure of this high chair is a fixed structure. The parts cannot be folded, the volume is large, the space is large, it is inconvenient to carry and use, and it cannot meet the growing needs of people.

Invention content:

The purpose of the present invention is to provide a linked foldable high chair which can fold the whole high chair, is convenient to fold, small in size and saves space, aiming at the shortcomings of the prior art.

In order to achieve the above object, the technical scheme adopted in the present invention is:

Linked collapsible high chair, it includes dinner plate, seat board, footrest, front chair foot and back chair foot, footrest is arranged under the seat board, dinner plate, seat board, footrest , The rear chair legs are respectively hinged on the front chair legs, the seat plate is linked with the pedals through the linkage rod, the seat plate is linked with the rear chair legs through the support rod, and the rear chair legs are linked with the dinner plate to rotate in the opposite direction With a unique structure, the seat plate can be synchronously linked to drive the dinner plate, the footrest and the rear chair legs to be folded or unfolded at the same time.

The front ends of the seat board and the footboard are respectively hinged to the middle and lower sections of the front chair feet, and the rear ends of the seat board and the foot board are respectively hinged with the two ends of the linkage rod.

The combination of the seat plate, the linkage rod, the pedal and the front chair feet constitutes a parallel four-bar linkage mechanism.

The top of the rear chair foot is hinged to the middle and upper section of the front chair foot, the top of the support rod is hinged to the seat plate, and the bottom of the support rod is hinged to the rear chair foot.

The rear chair legs link the dinner plate through the transmission mechanism.

The transmission mechanism is a gear mechanism or a link mechanism.

The beneficial effect of the present invention is that: the present invention comprises dinner plate, seat board, pedal, front chair foot and back chair foot, foot pedal is arranged below the seat board, and dinner plate, seat board, foot board, back chair The feet are respectively hinged on the front chair feet, and the dinner plate, footrest, and rear chair feet are respectively linked and connected with the seat board. Unfold, when you want to fold it, turn the seat up, and the seat will drive the plate, the footrest and the rear chair legs to be folded together at the same time, so that the entire high chair will be folded toward the front legs into a flat shape The structure is thinner, smaller in size, saves space, and is convenient to carry and store. The high chair can be unfolded for use by turning the seat plate downward. It is easy to fold and unfold, and convenient to use.

Description of drawings:

Fig. 1 is a structural representation of the present invention;

Fig. 2 is a structural schematic diagram during the folding process of the present invention;

Fig. 3 is a schematic structural view of the present invention in a folded state.

detailed description:

The present invention will be further described below in conjunction with the accompanying drawings. As shown in FIGS. Rear chair foot 5, linkage rod 6 and support rod 7, pedal 3 are arranged on the below of seat board 2, the top of rear chair foot 5 is hinged on the middle and upper section of front chair foot 4, and the rear end of dinner plate 1 is hinged on The middle and upper section of the front chair foot 4, the rear chair foot 5 and the dinner plate 1 are linked to form a structure that rotates in the opposite direction, and the front ends of the seat plate 2 and the pedal 3 are respectively hinged on the middle and lower section of the front chair foot 4, and the seat plate 2 and the rear end of the pedal 3 are respectively hinged with the two ends of the linkage rod 6, and the combination of the seat plate 2, the linkage rod 6, the pedal 3 and the front chair pin 4 constitutes a parallel four-bar linkage mechanism, and the support rod The top of 7 is hinged with seat plate 2, the bottom of support bar 7 is hinged with rear chair foot 5, and the combination of support bar 7, seat plate 2, front chair foot 4 and rear chair foot 5 constitutes a four-bar linkage mechanism, forming a seat plate 2 The synchronous linkage highchair that drives the dinner plate 1, the foot pedal 3 and the back chair foot 5 to be folded or unfolded at the same time.

The back chair foot 5 is linked with the dinner plate 1 through a transmission mechanism 8, wherein the transmission mechanism 8 can be a gear mechanism, a link mechanism or other mechanisms.

When it is to be folded, the seat board 2 is turned upwards, and the seat board 2 drives the pedal 3 to rotate upwards through the linkage rod 6, and at the same time, the seat board 2 drives the rear chair foot 5 forward through the support rod 7 Turn and fold, and the back chair foot 5 drives the dinner plate 1 to rotate downward to fold, so that the whole high chair is folded toward the front chair foot 4 into a flat structure, which is thinner, smaller in size, and saves space. It is convenient to carry and store, and the high chair can be unfolded for use by turning the seat board 2 downward, and it is easy to fold and unfold, and convenient to use.

Of course, the above descriptions are only preferred embodiments of the present invention, so all equivalent changes or modifications made according to the structures, features and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
