Description

double stroller

This creation is about a double stroller.

A general family may not only have one child or baby, but there may be more than two babies or children who need a stroller at the same time (because they may be one or two years old or twins), and most families today belong to small children. Families and office workers at the same time, so often a single housewife must take care of two children at the same time. At this time, if the housewife has to push two baby carriages when going out, it will definitely cause considerable inconvenience, and it is easier Because it cannot be fully taken care of, it may cause danger, so it cannot fully meet the practicability of housewives in use, so the double stroller was born accordingly;

Since the design of the double stroller is for housewives to carry two children more conveniently, it is not only the structural stability that must be considered, but also the practicality of the housewife. Or the characteristics of convenience and labor-saving when folding the double stroller, and the structure of the commonly used double stroller is shown in Figure 1 and Figure 2, which is mainly formed by combining two single strollers 10 and 20 The structure of the main body of the first and second baby carriages 10, 20 is composed of respective bottom bars 11, 21, bottom bar linkage bars 11', 21', second bottom bars 11", 21", The side bars 13, 23, the seat bars 14, 24 and the support bars 15, 25 are composed of a single stroller, while the common double stroller uses the same connecting bar 30 to combine two strollers. Single baby carriage 10,20 can make housewives cause considerable trouble in use like this, hereby discusses as follows with respect to above argument:

(1) When this kind of double stroller is to be folded, the bottom rods 11, 21 and the push rods 12, 22 of the first and second strollers 10, 20 must be bent and folded as shown in Figure 3 at the same time. The double stroller is folded. Although the illustration is simple, its action is not simple and rather troublesome, because when the bottom bar 11 of the first stroller 10 is folded, the bottom bar 11 will be affected by the two bottom bars on the one hand. Because the rod sub-rods 111 and 112 are folded at the same time, and the bottom rod sub-rod 111 must bear the stress of the rods of the second baby carriage 20 due to the reaction force of the second baby carriage 20, so the bottom rod cannot be completely and effectively 11 is folded, that is to say, it will affect the connecting rod 30, the component rods (not shown in the figure) of the second stroller 20, the side rod 23, the seat rod 24 and the side rod 13 and the seat rod 14 of itself at the same time. Therefore, when the housewives fold the bottom bar 11, they will feel that the pulling force of the second baby carriage 20 on the bottom bar sub-rod 111 and the bottom bar linkage bar 11' is very large; The second baby carriage 20 seems to also apply a reaction force, which makes it very difficult to fold the bottom bar 11 of the first baby carriage 10, and the bending degree is not large at one time, so the bottom bar 21 of the second baby carriage 20 must be quickly retracted. However, you will also feel that the first baby carriage 10 is also pulled by a reaction force, and the bending degree is not large, so when folding, the first bottom bar 11 is often required to be slightly folded first and then the second one. The bottom bar 21 is slightly folded, and then returns to the first bottom bar 11 and then folded in this order, which is quite cumbersome and inconvenient. This is one of the defects.

(2) If, as mentioned above, the two bottom bars 11,21 are folded at the same time, each member bar, side bars 13,23 and seat bars 14,24 of the first and second baby carriages 10,20 will still be affected at the same time. The relationship between the two bottom rods 11 and 21 must be bent by using both feet or both hands at the same time. Folding, so it is very troublesome to know that it is very troublesome to fold.

(3) Since this kind of double stroller is a combined structure of the first and second strollers 10, 20, it also costs a lot of materials, which will cause an increase in cost.

(4) The commonly used double stroller not only has such impractical disadvantages in folding, but also has the disadvantage that it is not easy to spread out because of the stress offset relationship when it is unfolded. It's quite inconvenient.

(5) The structure of the commonly used double stroller, because its bending control block 31 is arranged in the middle of the bottom bars 11, 21 of the two strollers 10, 20, so it can be offset by the mutual force when bending, so this The stress that the connecting rod 30 and the side bars 13, 23 are subjected to is quite large, which is why the connecting rod 30 is easily concave and double-shaped when the conventional double stroller is damaged.

The purpose of the utility model is to provide a double stroller, which can make folding the double stroller more convenient and labor-saving; and can enhance the structural stability and reduce the cost at the same time.

The technical scheme of the utility model is:
