Description

M257307 V. Creation Instructions (1) [Technical Field of Creation] This creation is a baby beam 44 ^ Λ1 a stroller with a horizontal and vertical folding frame: structure: structure should be installed at the same time with a swing element, the swing The components are movable M ..., and the car structure has at least one step of moving and folding. The moving cup is the same as that of the stroller when the skeleton of the stroller is folded. There are many types of structural methods of the two m = f cars, among which-can be fitted into the heart: :: pedal, and make The purpose of the cogging action is to make the braking effect to achieve the anti-step rear rotation _1 system, so when the i γ Renba brake is dropped, the two sides of the control system are controlled separately in real time. There are often unsteady children :::: slow fr baby stroller, or = as the security, Zunyi: L family pedals early and the function of bilateral synchronous braking · Same lever: with side synchronous braking '-in general There must be between the two brake levers-even the baby stroller is moved at the same time. However, if the link is only used for longitudinal folding, the link width will not be affected when folding. However, it is used for umbrella carriage baby carriage with both vertical and horizontal folding.

M257307 5. At the time of the creation description (2), 'the link must be folded at the same time when the stroller frame is folded, otherwise it will affect the number of folding of the frame, which is like the British patent GB222 75 6 5 A patent case', It mainly sets a pair of connecting rods between two brake levers, and installs a receiving box between the pair of connecting rods. The receiving box acts as a pedal, and the pair of connecting rods can slide in and close when the skeleton is folded. fold. " But 'the brake structure mentioned above, when the skeleton is folded, the pair of connecting rods slide into the receiving box in the direction of the fork and parallel to the receiving box, which is the same as the main folding direction (longitudinal). The vertical angle, therefore, when the pair of connecting rods and the accommodating slot in the accommodating box have an angle, it is prone to catch, and its influence is closed = smooth. heart

That is to provide a combination of a swinging element and a pair of operating brakes to receive the effect of a folding control element for the conventional brake system. However, it is necessary to keep the infant end system between the pivot rods when the car The synchronizing driver is pivoted by the component card control group. One step applies these detailed car structures to a new kind of stroller skeleton to a stroller and to the pair of swinging elements or release the baby, making it in the category of the pair of connecting rods, the narration of the creation and the smoothness of the creation of the creation of the book Provide single-step performance; including the control group, the other connecting lever is connected by the connecting rod, and when the pendulum is folded, it can be folded, so that it achieves the main purpose described and summarized in this article] The lack, except for the original double brake, the end is pivoted to the piece; make it move the moving elements on both sides at a step, and make it clear by the pendulum to the other. When folding, it affects the brake structure, and the folding is smooth. The rear side folding control lever swings at one end of the connecting rod, which is the same as the rear wheel of the stroller and the stroller frame.
