detailed description

as attached 1- Attached picture 3 As shown, a children's dining chair includes a dining chair frame and a seat mechanism arranged on the dining chair frame. Seat mechanism not shown , The seat mechanism generally includes a seat pan, a seat belt for restraining the child, and the like.

Dining chair frame includes: Pole frame 1 , front and strut frame 1 The side armrest frame which is pivotally arranged on the upper part of the 2 , with side armrests 2 The rear of the 13 pivotally connected backrest frame 3 , side armrest 2 Extendable side armrest frame 2 , side armrest 2 There is a side armrest on the 2 Armrest locking mechanism for length locking, backrest frame 3 The lower part and the strut frame 1 They are set to be rotated relative to each other, and the set to be rotated means that they can be directly connected to each other with a pivot, and can also be set to be rotated indirectly through a third component. thus allowing adjustment of the side armrest brackets 2 length of , Change the backrest accordingly 3 relative strut frame 1 Angle.

In this embodiment, the above adjustable backrest angle structure is applied to a foldable dining chair frame with an unfolded position and a folded position, and the dining chair frame is provided with a dining chair capable of locking the dining chair frame in the unfolded position locking mechanism. The dining chair locking mechanism is not the gist of the present invention. For example, by locking between two parts with a rotational relationship, the locking mechanism that constitutes the locking of the link mechanism dining chair frame can be used here.

Armrest locking mechanism includes unlock button 7 , unlock button 7 against the pole frame 1 , as attached 4 , attached 5 As shown, when the dining chair frame is transformed from the unfolded position to the folded position, such as the backrest frame 3 In first gear or in second gear, side armrest 2 relative strut frame 1 move closer, unlock button 7 strut 1 up so that the armrest locking mechanism is in the unlocked position. side armrest 2 The length is due to its own gravity and the backrest frame 3 The pulling force moving downward thus extends to the longest position, thereby also making the backrest frame 3 relative strut frame 1 Moving further down further reduces the folded volume of the high chair.

In this implementation, as shown in the accompanying drawing 1- Attached picture 5 As shown, the dining chair frame also includes:

front bracket 4 , front bracket 4 upper part, strut frame 1 upper and side armrests 2 The front of the 11 Phase pivot connection, can also be a side armrest frame 2 The front part alone with the front brace 4 the upper part or alone with the strut frame 1 the upper pivot connection;

seat frame 5 , seat frame 5 front and front bracket 4 via the fourth axis 14 Phase pivot connection, seat frame 5 The rear of the 12 with backrest 3 The lower part of the pivot connection;

link 6 ,link 6 front with seat frame 5 via the fifth shaft 15 rotationally connected, connecting rod 6 the rear of the strut frame 1 via the sixth shaft 16 connected in rotation, the fifth shaft 15 on the fourth axis 14 with the second shaft 12 between. the backrest 3 the lower part of the seat frame through 5 with connecting rod 6 Indirectly with strut frame 1 set in rotation. Not shown, if there is no seat frame 5 with connecting rod 6 , can also be a backrest 3 The lower part and the strut frame 1 Rotate and slide between each other, such as in a pole frame 1 Set a sliding piece on the slide, the backrest frame 3 The lower part of the slide is pivotally connected, the dining chair frame is in the folding process, the backrest frame 3 relative strut frame 1 Turn and move down.

side armrest 2 Including front section with strut frame 1 The first armrest bar of the upper phase rotation setting 17 , rear and backrest 3 via the third shaft 13 Pivotally connected second grab bar 18 , the first handrail 17 with second grab bar 18 Slidingly connected, the armrest locking mechanism is set on the first armrest bar 17 with second grab bar 18 between. first handrail 17 with second grab bar 18 A limit mechanism for prohibiting the relative disengagement of the two is arranged between them. The limiting mechanism is not the focus of the present invention, as long as it can prevent the two sliding parts from being separated, it can be used, such as in the first armrest bar 7 The rear part has the first hook, the second armrest bar 8 The front part has a second hook, when the first grab bar 7 relative to the second armrest 8 Elongated to the limit position, the first hook hooks the second hook.

as attached 6 shown, the unlock button 7 Slidingly installed on the second armrest along the up and down direction 18 front, unlock button 7 Turn set on the second armrest 18 is also possible. unlock button 7 with lock 8 , unlock button 7 with lock 8 One piece. The armrest locking mechanism also includes openings on the first armrest lever 17 Multiple positioning holes on the 9 , multiple positioning holes 9 along the first handrail 17 The length direction is distributed in the first handrail 17 Above, the armrest locking mechanism has a locked position and an unlocked position. When the armrest locking mechanism is in the locked position, the locking member 8 Insert in a positioning hole 9 Inside, when the armrest locking mechanism is in the unlocked position, the locking member 8 with all pilot holes 9 All disengaged, unlock button 7 with second grab bar 18 between locking pieces is provided such that the 8 stably inserted in the corresponding positioning hole 9 inner elastic 10 . positioning hole 9 With three, the armrest locking mechanism is able to lock the side armrest frames in three lengths so that the dining chair frame is in the extended position and the backrest frame 3 There are three different angle gears.

As mentioned above, we have fully described according to the purpose of the present invention, but the present invention is not limited to the above-mentioned embodiments and implementation methods. Practitioners in the relevant technical fields may make various changes and implementations within the scope permitted by the technical ideas of the present invention.
