The specific embodiment
A kind of embodiment of the flattening closing-folding mechanism according to the forward and backward wheels of perambulator of the present invention as shown in Figures 1 and 2, at least comprise the collapsible front wheels 12 of skeleton 10,, pair of rear wheels group 21, a driven unit 6.Wherein in the rear end of collapsible skeleton 10, at least can establish a pair of rear foot support 2, but respectively with the be coupling upper end of rear wheels 21 of the mode of horizontal rotation, driven unit 6 interlocks are after each between wheels 21 and collapsible skeleton 10, the rear wheels 21 of rotation interlock two by expansion or the folding of collapsible skeleton 10, make two rear wheels 21 can be separately simultaneously from going to the angle 20 that vertical rolling advances or the angle 30 partially turn 90 degrees, make by this two rear wheels 21 in perambulator from deployed condition 100 while being switched to the state 200 of folding, simultaneously all from turning 90 degrees general flat ground side by side in same plane, reach the folding flattening more that makes perambulator, reduce effect and the purpose of the packing volume of timber and storage and transportation space.
The forward foot in a step support 1 of the present embodiment utilizes the two ends of a pair of folding joint group 5 and a upper bracket 3 to be pivoted, and is tilted to forward and extends from folding joint group 5, in front bottom end, establishes a pivot connecting seat 11 for being coupling with the upper end of front wheels 12.
As previously mentioned, but front wheels 12 in the mode of horizontal rotation, be coupling in the pivot connecting seat 11 of collapsible skeleton 10 front ends; When two rear wheels 21 are gone to by interlock the angle 30 partially turn 90 degrees, front wheels 12 also can go to the angle parallel with rear wheels 21 manually or automatically.Front wheels 12 comprise a front-wheel seat 13 and a front-wheel 14, and wherein the upper shaft of front-wheel seat 13 is connected to pivot connecting seat 11, to downward-extension or interlocking one coupling assembling 15 with the front-wheel 14 that is coupling.The better one still can arrange a location control mechanism (not shown) on front-wheel seat 13, and it can only orientation be advanced or freely left and right revolution, promotes the alerting ability while turning.
In order to make front wheels 12 when two rear wheels 21 are gone to by interlock the angle 30 partially turn 90 degrees, automatically go to the angle parallel with rear wheels 21, can establish draw bar 16 interlocks between collapsible skeleton 10 and front wheels 12; When two rear wheels 21 go to the angle 30 partially turn 90 degrees, by the pivotable interlock draw bar 16 of collapsible skeleton 10, utilize the front wheels 12 of draw bar 16 interlock to the angle parallel with rear wheels 21.
Front end and the pivot connecting seat 11 of the draw bar 16 of the present embodiment are pivoted, rear end directly or through a pair of cross bar 17 is pivoted with seat support 4, when annexation will make collapsible skeleton 10 go to from deployed condition 100 state 200 of folding by this, must, by seat support 4 interlock draw bars 16, make front wheels 12 go to the angle parallel with two rear wheels 21 thereupon.
Two rear wheels 21 are socketed in respectively the lower end of two rear foot supports 2, or are socketed on the bottom of collapsible skeleton 10 rear ends in the mode of other horizontally pivoting, can turn to the angle 30 that an angle 20 and that vertically rolling is advanced turn 90 degrees partially.Rear wheels 21 comprise a rear wheel seat 23 and a trailing wheel 22.The radius sum of two trailing wheels is less than or equal to the wheelspan between two trailing wheels, and after each, wheels 21, when going to the angle 30 partially turn 90 degrees, are do not interlock each other or overlap.
The rear end of the collapsible skeleton 10 of the present embodiment is pivoted a upper bracket 3, respectively establishes a pivot ear 31 in 32， both sides, Ke Sheyi grip part, the upper end of upper bracket 3 and is pivoted with the upper end of rear foot support 2.Actuator 61 interlocks are between upper bracket 3 and rear foot support 2, and driven unit 6 comprises an actuator 61, a sliding part 65, a moving part 62.Wherein actuator 61 is installed on collapsible skeleton 10, and can launch and fold and rotate with collapsible skeleton 10, then via moving part 62 interlock sliding parts 65.
Sliding part 65 is placed in rear foot support 2 in the mode that rotatably can not only slide, its mode of reaching is included on rear foot support 2 establishes an elongated slot 662, can establish one first fixed orifice 652 in order to fix one first pin 64 on sliding part 65, allow by this first pin 64 pass and to be entrapped in the set driving skewed slot 25 in socket part 24 with end in elongated slot 662; Up pulled sliding part 65 when actuator 61 by upper bracket 3 interlocks and during compression reseting spring 63, the first pin 64 will drive skewed slot 25 by pushing tow thereupon up moving, the component that pushing tow produces by this turns rear wheel seat 23; And, after above-mentioned situation about up being pulled is removed, by retracing spring 63, sliding part 65 is down passed again and the first pin 64 is moved down, see through and drive the reverse rear wheel seat 23 that turns of skewed slot 25, make to get back to the angle 20 of originally vertically rolling and advancing.
Although the embodiment shown in Fig. 3 is fixed in the first pin 64 on sliding part 65, and can move up by moving part 62 up pulls sliding part 65, or move down toward pressing down by retracing spring 63, yet in the situation that omit sliding part 65, also can be with reference to the alternate embodiment shown in figure 9, directly allow moving part 62 be connected with the first pin 64, and allow the first pin 64 pass and to be entrapped in the set driving skewed slot 25 in socket part 24 with end in the elongated slot 662 of rear foot support 2, equally also can produce the effect that turns rear wheel seat 23 starts.
The better one, can establish vertical section 28 in the upper end that drives skewed slot 25, when the first pin 64 slides into upper vertical section 28, can use the angle 30 that exactly rear wheels 21 is positioned partially to turn 90 degrees, and avoids rocking.In like manner, also can establish vertical section 27 in the lower end that drives skewed slot 25, just can exactly rear wheels 21 be positioned to the angle 20 of vertically rolling and advancing when the first pin 64 slides into lower vertical section 27, make angle orientation more clear and definite, avoid the unnecessary left and right rolling that turns.
Moving part 62 can be a flexible wire or stiff member, connect between actuator 61 and sliding part 65, when actuator 61 moves with collapsible skeleton 10, must be via moving part 62 interlock sliding parts 65, the driving skewed slot 25 that passes rear wheel seat 23 via the first pin 64 forces the angle 20 that rear wheel seat 23 advances from vertical rolling to turn to the angle 30 partially turn 90 degrees.When moving part 62 is embodied as a flexible wire, still need on sliding part 65 and connect a retracing spring 63, while with convenient moving part 62, discharging sliding part 65, utilize the strength of retracing spring 63 to make sliding part 65 repositions and make rear wheel seat 23 be held in the angle 20 that vertical rolling is advanced.
