The specific embodiment

Shown in Fig. 2,3, the utility model is provided with the perambulator 1 that leans against setting device and comprises support 2, is assembled in setting device 3 and wheel 4 on the support 2.

Shown in Fig. 3,4,5, support 2 comprises preceding bar 21, be articulated in before back bar 22, the two ends of bar 21 first halves be articulated in respectively before bar 21 and the lower part of back bar 22 seat bar 23, articulate the back of the body bar 24 in present bar 23 stage casings and be pivoted to about several connecting rods 25 of two back of the body bars 24.Wherein, seat bar 23 is used to support the seat cushion (not shown), and back of the body bar 24 is used for support and leans against (not shown).

Setting device 3 comprises actuating fabricate block 31 and flexible fabricate block 32.

As shown in Figure 6, this actuating fabricate block 31 comprises base 311, is combined in the slide block 312 of base 311 and pass second flexible element (for example ribbon or hawser) 313 of slide block 312 slidably.

At least two (present embodiment is an example with four) projections 3115 that base 311 comprises base plate 3112, becomes the end difference 3114 of L shaped extension from the vertically extending accessory plate 3113 in base plate 3112 tops, from base plate 311 left and right sides, extend from the Surface Vertical of base plate 3112.The bearing of trend of the bearing of trend of these projections 3115 and accessory plate 3113 is respectively in the opposite sides of base plate 3112.

The start plate 3123 that slide block 312 comprises mainboard 3121, is formed on the elongated slot 3122 of mainboard central authorities, three vertical bendings are extended from mainboard 3121 tops, extend upwardly to the flank 3124 of start plate 3123, three vertical bendings are extended from mainboard 3121 left and right sides alar parts 3125 from mainboard 3121 tops, from alar part 3125 towards mainboard 3121 vertically extending two tongue pieces 3126.This flank 3124 and start plate 3123 define guide hole 3127, and this tongue piece 3126 and alar part 3125 define groove 3128.

Should flexible fabricate block 32 comprise pedestal 321, plate body 322, rotatably be assembled in the pulley 323 of pedestal 321 1 ends, pivotly be assembled in elastic component 325, the pile warp pulley 323 of block piece 324 below pedestal 321 other ends, this block piece 324 of bias voltage and pass pedestal 321 and be connected to an end of block piece 324 first flexible element 326 (for example steel wire), be fixed to the ring 327 of first flexible element, 326 other ends.

Plate body 322 is formed with first protuberance 3221 that is positioned at the side and is positioned at the oblique depression 3223 of row of lower end.Pedestal 321 is formed with passage 3211 longitudinally and extends the second protuberance (not shown) of charging in the passage 3211.

Assembling

As Fig. 4,5,6, shown in, second flexible element 313 that will activate fabricate block 31 earlier passes the guide hole 3127 of slide block 312, secondly the end of second flexible element 313 is passed the ring 327 of flexible fabricate block 32, and second flexible element 313 and ring 327 are combined in the mode of for example sewing.

Insert from the upper end of the groove 3128 of slide block 312 with the lower end of the end difference 3114 of base 311 then.Pass elongated slot 3122, base 311 and the connecting rod 25 of slide block 312 again with bolt or rivet, make four projections 3115 of base 311 prop up the connecting rod 25 of two intersections respectively simultaneously, and base 311 is fixed on the connecting rod 25, rotate with respect to connecting rod 25 to prevent base 311.

At last, the plate body 322 of flexible fabricate block 32 is placed the passage 3211 of pedestal 321, and an end that makes plate body 322 protrudes from outside the pedestal 321, and an end of the pedestal 321 of the fabricate block 32 that will stretch again is pivoted to back of the body bar 24, and aforementioned plate body 322 protrudes from pedestal 321 outer ends and is pivoted to back bar 22.

Operation

Shown in Fig. 4,6,7, the general state when not forcing in start plate 3123, the end of block piece 324 is positioned at one of them depression 3223 of plate body 322.Because depression 3223 and block piece 324 all are tilted to the right (that is the direction of extending towards plate body 322 tilts), make plate body 322 to slide to the right, but can not slide left with respect to pedestal 321.That is when this state, total length after pedestal 321 and plate body 322 combinations can only extend and can not shorten, make angle between back of the body bar 24 and the seat bar 23 to diminish and to become big,, cause this angle to become big suddenly and cause danger to prevent to be seated at baby in the perambulator 1 bar 24 application of forces that support or oppose.

Shown in Fig. 4,6,8, upwards force in start plate 3123 with finger, slide block 312 is slided towards the direction near accessory plate 3113.Slide block 312 interlocks second flexible element 313, first flexible element 326 and block piece 324 make block piece 324 rotate the depression 3223 that breaks away from plate body 322 up to the end of block piece 324 in the clockwise direction.Plate body 322 can slide with the combination total length of elongation plate body 322 and pedestal 321 to the right or slided left to shorten the combination total length of plate body 322 and pedestal 321 with respect to pedestal 321 this moment, adjusted the angle of back of the body bar 24 with respect to seat bar 23 by this.

Shown in Fig. 4,6,9, when stopping to force in start plate 3123, block piece 324 rotates in the end of block piece 324 is contained in another depression 3223 of plate body 322 in the clockwise direction via the restoring force of elastic component 325.Reverting to plate body 322 this moment again can only slide to the right but the state that can not slide left with respect to pedestal 321, temporarily remains on another different angles with respect to seat bar 23 and will carry on the back bar 24.

When plate body 322 extends to the right when sliding into the limit with respect to pedestal 321, first protuberance 3221 of plate body 322 props up second protuberance of pedestal 321, and this moment, plate body 322 can not continue to extend slip more to the right, broke away from pedestals 321 to prevent plate body 322.

But the above, it only is preferred embodiment of the present utility model, when not limiting the scope that the utility model is implemented with this, promptly the simple equivalent of being done according to the utility model claims and utility model description generally changes and modifies, and all should still belong in the scope that the utility model patent contains.
