The specific embodiment
Such as the baby virgin go-cart skeleton embodiment of Fig. 1 to finger shown in Figure 7, receive frame 2 by left folding receipts frame 1 and a right folding at least and be formed by connecting.Left folding is received frame 1 and is received frame 2 with right folding and comprise respectively a front foot pipe 21, a rear foot tube 22, a handle pipe 24 and an interlocked limited mechanism 5 etc., is assembled into a pipe group that can pivot and fold along a vertical surface.
Shown in Fig. 4,5, handle pipe 24 slidably reaches pivotally and articulates with socket joint 23.The handle pipe 24 of the present embodiment is provided with a long and narrow guide groove 11 and slides and pivot along socket joint 23 for it; Socket joint 23 is provided with a guide pillar 12 and passes guide groove long and narrow on the handle pipe 24 11, handle pipe 24 can be slided, pivot and not break away from along the guide pillar 12 of socket joint 23, thereby can slide, pivot to fold and to launch with respect to front foot pipe 21.
The better one can establish a folding lockout mechanism 6 at the virgin go-cart skeleton 10 of baby, launches longitudinally and folds to control it, enables to remain in one and launch stationary state 100 after launching, and become a folding state 200 after release.
As shown in Figure 3, the folding lockout mechanism 6 of the present embodiment is established a positioning groove 61 in the upper end of front foot pipe 21, establish positioning piece 62 and an elastic parts 64 in handle pipe 24 lower ends; In addition, operationally establish a remote operation part 65 in the upper end of handle pipe 24, utilize a moving part 63 along the inside of handle pipe 24 or outside interlock between remote operation part 65 and locations 62.In launching stationary state 100 times, the locking of folding lockout mechanism 6 can make handle pipe 24 and front foot pipe 21 continue and roughly in line.
Elastic parts 64 is located at locations 62 1 ends so that bias voltage to be provided, and makes locations 62 keep snapping in positioning groove 61, thereby the end of handle pipe 24 and front foot pipe 21 upper ends are locked in together.Moving part 63 can be general flexible component, and remote operation part 65 can be embodied as the handle that sliding sleeve maybe can be pulled, and via the interlink function of moving part 63, makes locations 62 break away from positioning groove 61 when it is spurred or pulls.When locations 62 broke away from positioning groove 61, handle pipe 24 just can pivot and past lower slider towards front foot pipe 21 with respect to socket joint 23, reaches folding state 200 as shown in figure 11.
Such as Fig. 1, Fig. 8, Figure 10 and shown in Figure 11, by one first folding group 3 and 4 connections of one second folding group, make left folding receipts frame 1 and right folding receive frame 2 in lockable mode and be able to the laterally relative close in reverse direction expansion that reaches between left folding receipts frame 1 and this right folding receipts frame 2.
The first folding group 3 is located at the virgin go-cart skeleton of baby 10 rear sides, can be consisted of by the iron plate group 31 that plural pieces can fold relatively, by the folding and launching of iron plate group 31, drive left folding receive frame 1 and right folding receive frame 2 laterally relative near and make baby child go-cart skeleton 10 become folding state 200.Launch in reverse direction when iron plate group 31, can drive left folding and receive frame 1 and right folding receipts frame 2, the virgin go-cart skeleton 10 of baby is become launch stationary state 100.
As shown in Figure 1, the second folding group 4 can be embodied as a pair of crossing rod piece 41 that articulates each other, its front end and handle pipe 24 ends or front foot pipe 21 directly or indirectly articulate, the rear end then articulates with rear foot tube 22, by this each other rotation of articulated section of centre to crossing rod piece 41, make left folding receive frame 1 and receive thereupon laterally relative close and in reverse direction expansion of frame 2 with right folding.
The better one, the left folding of the present embodiment is received frame 1 can establish respectively a mounting bar 7 symmetrically with right folding receipts frame 2.Mounting bar 7 can be articulated between handle pipe 24 and rear foot tube 22 and the front foot pipe 21, and utilizing weaves cotton cloth to be connected between the two mounting bars 7 can consist of a seat.When the virgin go-cart skeleton 10 of folding baby, mounting bar 7 is driven by handle pipe 24, can affect rear foot tube 22 to make toward front foot pipe 21 closings.
Such as Fig. 7 and shown in Figure 9, interlocked limited mechanism 5 is installed between the lower end of front foot pipe 21 and handle pipe 24, uses restriction handle pipe 24 with respect to the opening angle of front foot pipe 21, with the gap of avoiding in folding or producing tong when launching the virgin go-cart skeleton 10 of baby.A spacing connecting rod 51 is contained in the interlocked limited mechanism 5 of the present embodiment, is articulated in front foot pipe 21 with an end, and the other end is articulated in 11 li of the guide grooves of handle pipe 24 slidably, makes handle pipe 24 when relative front foot pipe 21 pivots, and the angle of opening is controlled.
When the virgin go-cart skeleton 10 of folding baby, should remove first the lock-out state of folding lockout mechanism 6, handle pipe 24 is pivoted and the front foot pipe 21 and sliding (as shown in Figure 9) of staggering downwards.At this moment handle pipe 24 will drive spacing connecting rod 51, make from a primary importance 54 and be switched to a second place 55.
Interlocked limited mechanism comprises that also one resets protruding 52, is fixed in the lower end of handle pipe 24.When the virgin go-cart skeleton 10 of baby will launch, handle pipe 24 up must be taken out height, and up take out in the high process in handle pipe 24, the protruding grain 52 that resets of its lower end will promote spacing connecting rod 51, make spacing connecting rod 51 go back to original residing primary importance 54 from the second place 55.
One end of spacing connecting rod 51 is articulated in front foot pipe 21, the other end then is provided with a lateral projections 53, slidably articulate by the guide groove 11 of lateral projections 53 with handle pipe 24, so that spacing connecting rod 51 is when handle pipe 24 and front foot pipe 21 are pivoted relative to each other, guide groove 11 interior slips that can be in handle pipe 24, restriction handle pipe 24 is with respect to the gap of opening of front foot pipe 21.
To shown in Figure 11, when the virgin go-cart skeleton 10 of baby was in expansion stationary state 100, spacing connecting rod 51 was positioned at a primary importance 54 such as Fig. 1, Fig. 2, Fig. 7; When discharging folding lockout mechanism 6, handle pipe 24 pivots with respect to socket joint 23 and staggers and past lower slider with front foot pipe 21, this moment, spacing connecting rod 51 was subjected to handle pipe 24 drivings will turn to a second place 55, handle pipe 24 only can be pivoted in the scope of the pivotal point of spacing connecting rod 51 and lateral projections 53, with the maximum opening angle of control handle pipe 24 with respect to front foot pipe 21, avoid producing the gap that is enough to tong; The better one should make the maximum clearance after opening between handle pipe 24 and the front foot pipe 21 be no more than 5mm.
As shown in figure 10, after handle pipe 24 and front foot pipe 21 stagger, continue toward lower slider, will roughly overlap with front foot pipe 21 at last and dwindle baby child go-cart skeleton 10, finish at last folding state 200 as shown in figure 11.The better one can by bottom and the rear wheels 26 common formation strong points of handle pipe 24, be stood the skeleton 10 after folding independently.
When operator's wish is launched the virgin go-cart skeleton 10 of baby, can upwards take out high handle pipe 24, make with respect to front foot pipe 21 upward slidings, and under the restriction of spacing connecting rod 51, pivot, pivot and promote spacing connecting rod 51 by the protruding grain 52 that resets, make spacing connecting rod 51 be turned back to primary importance 54 from the second place 55, allow the locations 62 of folding lockout mechanism 6 snap in positioning groove 61, the virgin go-cart skeleton 10 of baby is fixed in launches stationary state 100.
