Referring to fig. 1 to 3, the present application provides a child dining chair 1000 with adjustable seat (hereinafter referred to as child dining chair 1000), which comprises two opposite supporting frames 100, a fixed seat 200 disposed between the two supporting frames 100, and a seat plate 300 slidably disposed on the fixed seat 200. The child dining chair 1000 further includes a backrest 500 for supporting the back of a child, the seat pan 300 being configured to carry the child, the seat pan 300 being configured to slide and have a plurality of different seat depths relative to the backrest 500, such as the seat pan 300 being configured to slide away from the backrest 500 in fig. 3, with the seat depths corresponding to the seat depths.
As shown in fig. 4 to 6, the seat plate 300 is provided with a plurality of locking portions 310 in the sliding direction thereof. The child dining chair 1000 further comprises a locking member 210 and a driving member 220, wherein the locking member 210 is arranged on the fixed seat 200 and can be elastically deformed, and has a locking state of being combined with the locking portion 310 to limit the sliding of the seat plate 300 and an unlocking state of being separated from the locking portion 310. The driving member 220 is movably disposed on the fixing base 200, and acts on the locking member 210 to deform and switch between a locked state and an unlocked state, and once the driving member 220 releases the action on the locking member 210, the locking member 210 deforms, resets and switches to another state.
For example, the driving member 220 releases the locking member 210, the locking member 210 is in the unlocked state, the driving member 220 moves and acts on the locking member 210, and the locking member 210 is switched to the locked state (as shown in fig. 6).
The child dinning chair 1000 of the application utilizes the elastic deformation capability of the locking piece 210 and cooperates with the driving piece to realize state switching, and compared with the prior structure, the child dinning chair of the application omits a spring and has simpler structure.
With continued reference to fig. 6, in an embodiment, the locking member 210 and the fixing base 200 are integrally formed, so that an assembling operation between the two is omitted, and assembling is simplified. Wherein the locking member 210 has a fixed end 211 coupled to the fixing base 200 and an opposite movable end 212, the movable end 212 being coupled to the locking portion 310. The movable end 212 has larger deformation than the fixed end 211, which is more beneficial to the switching of the two states.
Specifically, the back of the seat 300 is provided with a rack 320 having a plurality of locking parts 310, that is, the locking parts 310 have a tooth-shaped structure, and the locking member 210 has engagement teeth 213 engaged with the rack 320. In the illustration, the locking member 210 has a sheet structure, the engaging teeth 213 are located on the surface of the locking member 210 facing the rack 320, and the engaging teeth 213 are plural, that is, plural engaging teeth 213 are combined with plural locking portions 310, so as to improve the locking effect.
In an embodiment, the driving member 220 includes a cam 221 rotatably disposed on the fixing base 200 and an operating handle 222, and the cam 221 presses a surface of the movable end 212 opposite to the engaging teeth 213, so that the locking member 210 is combined with the locking portion 310. In particular use, the operating handle 222 is held and rotated to rotate the cam 221 such that the cam 221 presses against the movable end 212 or releases the action on the movable end 212.
In an embodiment, the bottom of the fixing base 200 has a recess 230, and in the locked state, the locking member 210 and the driving member 220 are hidden in the recess 230, so that the appearance is more concise. As shown in fig. 6, the extending direction of the locking member of the sheet structure from the fixed end 211 to the movable end 212 is gradually upward; the driving member 220 is disposed below the locking member 210, and the operating handle 222 extends toward the fixed end 211, thereby fully utilizing the space and satisfying the aforementioned hiding effect.
Wherein the end of the operating handle 222 extends downward and forms a gap 240 with the fixed end 211 into which a hand is inserted.
As shown in fig. 7 to 11, in an embodiment, a guiding mechanism is provided between the fixing base 200 and the seat plate 300, and the guiding mechanism includes:
The guide rail 250 is arranged on the fixed seat 200 and extends along the sliding direction of the seat plate;
The sliding seat 330 is fixedly connected to the bottom of the seat plate 300 and is slidably disposed on the guide rail 250. Preferably, the number of guide rails 250 is a plurality, such as two in the illustration.
The sliding stroke of the seat plate 300 (equivalent to the sliding stroke of the slider 330) has two extreme positions, which respectively correspond to a first extreme position with the largest seat depth in fig. 10 and a second extreme position with the smallest seat depth in fig. 11. The fixing base 200 is provided with a limiting part 260 which is propped against the sliding seat 330 to enable the seat plate 300 to stay at two limit positions. The number of the limiting parts 260 is two, and the limiting parts are formed as follows:
the reinforcing rib 261 is integrally formed with the fixing base 200;
and/or a stopper 262, which is detachably coupled to the fixing base 200.
Referring back to fig. 1, in one embodiment, the child dinning chair 1000 further comprises a fence 600 coupled to the holder 200 and the backrest. Wherein the enclosure 600 includes a side wall 610 engaged with the backrest 500 and a bottom wall 620 engaged with the fixing base 200. In the second limit position of the seat plate 300, the enclosure 600 can be installed, and the seat plate 300 is limited by the bottom enclosure 620 and cannot slide, which is suitable for smaller children, and safety is improved by the enclosure 600. In one embodiment, the child dining chair 1000 includes a footrest 400 disposed between the two support frames 100, wherein the footrest 400 and the fixed base 200 slide relative to the two support frames 100 to adjust the height.
In the face of older children, the child has some safety awareness, the enclosure 600 can be removed, and the seat plate 300 can be moved to adjust the proper seat depth, so that the child dinning chair can be used close to the edge of the table for improving the safety.
In the child dining chair, the locking part can be combined with or separated from the locking part by utilizing the elastic deformation capacity of the locking part, so that the child dining chair omits a spring compared with the prior art and has a simpler structure.
The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description. When technical features of different embodiments are embodied in the same drawing, the drawing can be regarded as a combination of the embodiments concerned also being disclosed at the same time.
