The specific embodiment
Below with reference to the accompanying drawings preferred embodiment of the present utility model is described.
Doll carriage skeleton 10 embodiment shown in accompanying drawing 1 to 7, it comprises: left folding is received frame, right folding is received frame, the first folding group 5, the second folding group 6, a pair of slide 7 and collapsible stretcher group 13.
Left folding receives frame and right folding receipts frame is assembled by front foot pipe 1, rear foot tube 2, socket joint 12 and handle pipe 3 respectively, can roughly fold along vertical surface.Wheels 11 before the lower end of front foot pipe 1 connects wherein, the upper end then connects socket joint 12.Rear foot tube 2 upper ends and socket joint 12 articulates, and the lower end connects back wheels 21, when doll carriage skeleton 10 is in deployed condition 100 shown in the accompanying drawing 1, can with preceding wheels 11 together support doll carriage skeleton 10 rollably, enable to push away the baby like a cork and go about.
The upper end of handle pipe 3 is provided with handle 31 and grips for the operator, moves to make things convenient for it to promote doll carriage skeleton 10.The handle pipe 3 of present embodiment is a telescopic pipe, adjusts length with respect to front foot pipe 1, to adapt to the people of different heights.The better one can establish a location mechanism 4 between handle pipe 3 and socket joint 12 or front foot pipe 1, the flexible location of handle pipe 3 is provided.
Each slide 7 is connected in the left and right rear end that folds frame respectively slidably, for example along rear foot tube 2 upper and lower slips, in order to the upper end that drives the first folding group 5 and the rear end of the second folding group 6.
Collapsible stretcher group 13 is articulated in the left and right front end that folds frame, comprises first stretcher 14 and crus secunda pedal 15.First stretcher 14 and the crus secunda pedal 15 of this example articulate each other, and both end opposite are articulated in the left and right front foot pipe 1 that folds frame respectively; Fold that frame laterally folds and each other during closing when left and right, to drive first stretcher 14 folds with crus secunda pedal 15, end 16 is outstanding and integral body is X shape, Y shape or V shape from the articulated section, and can be connected to ground and doll carriage skeleton 10 after the auxiliary whole folding is stood voluntarily, for example become the state that folds 200 shown in the accompanying drawing 7.
The lower end system of the first folding group 5 is articulated in the lower end of rear foot tube 2, and the upper end is articulated in slide 7 and with its upper and lower moving, uses left and right rear end horizontal spreading and the closing folding that folds frame of interlock.The present embodiment first folding group 5 can comprise that first intersects rod member 51, when its upper end up run with slide 7 and widen with the lower end apart from the time, will drive the left and right horizontal closing in rear end that folds frame and folding; Otherwise, down runs with slide 7 and during near the lower end, the left and right rear end that folds frame of drive is laterally opened when its upper end, can be the deployed condition 100 shown in the accompanying drawing 1 at last.
The front end of the second folding group 6 is articulated in collapsible stretcher group 13, and the rear end is articulated in slide 7 and moves up and down with it.The better one, as shown in Figure 4, the second folding group 6 can be embodied as the second intersection rod member 61, its rear end is subjected to when up mobile first to intersect the drive of rod member 51 and constriction with slide 7, its front end articulate with collapsible stretcher group 13 and with the rear end constriction, this first stretcher 14 and crus secunda pedal 15 will be taken place as accompanying drawing 3 and accompanying drawing 4 in the amounting to of the direction illustrated of arrow.
As shown in Figure 5, the second folding group 6 also can be embodied as a pair of non-intersection rod member 62, articulates collapsible stretcher group 13 with its front end respectively, and is articulated in this to slide 7 with the rear end.When slide 7 is up mobile, via the upper and lower interlock of non-intersection rod member 62, collapsible stretcher group 13 is folded, and draw the left and right front end that folds frame of both sides over to one's side, make both mutual closings.
The better one, present embodiment also can comprise a mounting bar 9, is articulated between slide 7 and the front foot pipe 1, weaves cotton cloth and forms the seat of a doll carriage for placing.
During folding doll carriage skeleton 10, remove the detent mechanism 4 between handle pipe 3 and socket joint 12 or the front foot pipe 1 earlier, handle pipe 3 is able in the retraction front foot pipe 1.When up spurring slide 7 or being located at the handle (not shown) of the first folding group, 5 infalls, the upper and lower distance that can make the first folding group 5 is elongated and width shortens, this makes slide 7 and then up move the upper end of the first folding group 5, thereby spur the rear end of the second folding group 6, make the left and right front foot pipe 1 and rear foot tube 2 mutual closings that folds frame.At this moment, because the width constriction of the first folding group 5 is finished folding so also will drive the left and right frame that folds simultaneously to the intermediate lateral closing.
Folding state 200 as shown in Figure 7, wherein first stretcher 14 can constitute most the strong points with preceding wheels 11 with the end 16 of crus secunda pedal 15, and the doll carriage skeleton 10 after folding is stood independently.
Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.
