Description

Seat quick release mechanism for baby stroller

technical field

The invention relates to a seat quick dismantling mechanism, in particular to an innovative mechanism capable of quickly disassembling and assembling the seat arranged on the frame of the stroller.

Background technique

Early baby strollers were unable to change directions because the push handles were fixed, so the push handles could only face a single direction inclined at the rear of the baby stroller, so the pusher could only stand on the side of the baby pushchair. Push the baby stroller from the back of the car, and because the baby’s face is facing forward when sitting on the baby stroller, so that the pusher can’t see the baby’s facial expressions and body movements at all, and the baby can’t May feel restless because you cannot see the person pushing the cart.

Therefore, the related industry has actively developed a baby stroller with a reversible handle of the stroller, so that the baby sitting on the stroller and the pusher who pushes the stroller can face to face. The sight of each other makes infants feel more at ease because they can see the pusher, and the pusher can always pay attention to every move of the infant to avoid dangerous things.

For example, China Taiwan Announcement No. I221129 (Baby Stroller), Announcement No. (574988) (Foldable Stroller), Announcement No. 543577 (Baby Stroller Push Handle Reversing Structure (2)) and Announcement No. M392781 (Baby Stroller Push handle reversing structure (three)), aforementioned each case all is the patent case for pushing handle reversing structure.

In addition, there are also some operators who aim to change or adjust the seat so that the infant and the pusher can face each other, such as China Taiwan Announcement No. I341802 (Locking Mechanism of Child Safety Seat and Baby Carriage) Child Safety Seat Fixing Device), Announcement No. M297870 (car seat that can be snapped into the baby stroller), this kind of baby stroller also has the advantage that the seat can be removed from the baby stroller to facilitate the application For safety seats or dining chairs installed in the car.

detailed description

In order to have a more complete and clear disclosure of the technical content used in the present invention, the purpose of the invention and the effects achieved, the specific implementation of the present invention will now be described with reference to the accompanying drawings:

Please refer to Figure 1 and Figure 2. The seat quick removal mechanism of the baby stroller of the present invention is to install a plate body 2 on the frame 1 of the baby stroller, and the plate body 2 is provided with several sets of telescopic sliding components 3 and a controllable turning operation Rod 4 and a turntable 5 are combined on the bottom surface of the disc body 2 in a rotatable state. The rotation state of the turntable 5 is controlled by turning the operating lever 4. The rotation path of the turntable 5 corresponds to the sliding assemblies 3, so that The rotation of the turntable 5 controls the shrinking or protruding of the sliding components 3; a seat 6 is correspondingly arranged on the disc body 2, and the inner edge of the bottom of the seat 6 is provided with a locking edge 61, and the sliding components 3 Correspondingly protruding above the locking edge 61 to limit and stop the locking edge 61, fix the seat 6 on the stroller frame 1, and turn the operating lever during operation 4 interlocking this rotating disk 5 rotations.

Wherein (please refer to Fig. 3, Fig. 4, Fig. 5, Fig. 6 at the same time below), a toggle piece 41 is protruded on the operating rod 4, and a notch 51 is provided at the corresponding toggle piece 41 on the dial 5, and the notch 51 For the toggle piece 41 to pass through, when the operating lever 4 is turned, the dial 41 can be used to push the turntable 5 to rotate; in addition, the turntable 5 is provided with a plurality of slotted holes 52, and a plurality of locking members 53 pass through the turntable 5. These long slots 52 are locked on the disc body 2, on the one hand, the disc body 2 and the turntable 5 are fixed, and on the one hand, the rotation angle of the turntable 5 is limited by these long slot holes 52; in addition, the turntable 5 and the disc body 2 An elastic return member 54 is arranged between them, and the elastic return member 54 is compressed when the operating rod 4 is turned to push the turntable 5 to rotate, and the restoring force generated by the elastic return member 54 after the operating rod 4 is released makes the The turntable 5 resets; and, the disc body 2 is provided with several sets of grooves 21, each set of grooves 21 is correspondingly accommodated in each sliding assembly 3, and the sliding assembly 3 includes a sliding member 31 and a first sliding assembly. An elastic member 32, the end of the sliding member 31 towards the outside protrudes with a first tenon 311, and the seat 6 is provided with a catch stop edge 61 corresponding to the first tenon 311, the first tenon 311 can Corresponding to the locking edge 61 of the seat 6, the first elastic member 32 is arranged between the inner end of the sliding member 31 and the disc body 2, so as to provide the elasticity of the sliding member 31 for protrusion and retraction; Moreover, the bottom surface of the slider 31 is further provided with a first slope 312, and the upper surface of the turntable 5 is protruded with a plurality of abutment blocks 55 corresponding to the sliders 31, and the abutment block 55 has a second slope 551, and the second slope 551 contact with the first slope 312 . Furthermore, at least one latch assembly 7 capable of protruding and retracting is provided on the disc body 2. The seat 6 is provided with two latch holes 62 opposite to each other. The latch assembly 7 includes a latch 71 and a second elastic member 72, the latching member 71 is provided with a pressing end 711 at one end facing the outside, and the second elastic member 72 is arranged between the inner end of the latching member 71 and the disc body 2, providing the The latching part 71 is elastically protruding and shrinking, and the middle section of the latching part 71 is protrudingly provided with a second tenon 712, and the second tenon 712 can be correspondingly snapped into any latch hole 62 of the seat 6, When the latch assembly 7 is in the protruding state, it can correspondingly extend into any latch hole 62 to fix the installation direction of the seat 6 .

Usually, when the seat 6 is set on the stroller frame 1 facing forward, the first tenon 311 of the sliding member 31 of the sliding assembly 3 protrudes above the locking edge 61 of the seat 6 , so that the first tenon 311 of the sliding member 31 is limited by the stop edge 61 of the seat 6 , thus the seat 6 is assembled on the frame 1 of the stroller.

When changing the seat 6 originally facing forward to face backward, press directly from the pressing end 711 of the latch 71 of the latch assembly 7, so that the second tenon 712 is disengaged from one of the bolts of the seat 6. In the locking state of the locking hole 62, the first tenons 311 of the sliding parts 31 of the sliding assemblies 3 still protrude above the locking edge 61 of the seat 6, so they can rotate on the disc body 2 Seat 6, until the seat 6 faces the rear side, release the latch 71 of the latch assembly 7, so that the latch 71 returns to its original position driven by the restoring force of the second elastic member 72, and the latch The second tenon 712 of the lock member 71 is engaged with the other latch hole 62 of the seat 6 to fix the seat 6 with the adjusted front facing the rear side.

If the seat 6 is to be removed from the stroller frame 1, the operating lever 4 is directly turned to make the operating lever 4 push the rotating disc 5 to rotate with its toggle piece 41, and the rotating angle of the rotating disc 5 will be affected by a long time. The length limit provided by the slot hole 52; and when the turntable 5 rotates, it will force the second slope 551 of the turntable 5 to push against the first slope 312 of the sliding assembly 3, so that the turntable 5 drives the sliding parts 31 of the sliding assemblies 3 shrink, so that the first tenon 311 is out of the state of protruding above the catch edge 61 of the seat 6. At the same time, because the second tenon 712 has a slope and is flexible, the seat can be moved at this time. 6 Remove from the stroller frame 1.

When the operating lever 4 is released, the turntable 5 drives the turntable 5 and the sliders 31 of the slide assemblies 3 back to original location.
