Description

The invention relates to vehicles, in particular to baby stakes.

A known design for a folding baby wheel includes a running gear consisting of articulated struts. At the ends of the front and rear struts are wheels. The seat frame is pivotally connected in front to the handle and at the rear with wheels and with the main frame 1.

The disadvantages of such a box are the design complexity and the impossibility of installing a winter box.

Also known is a baby folding stroller containing a running gear made in the form of a carrying frame of a frame connected to articulated front rear struts, at the ends of which running wheels are mounted and mounted on the front struts with the possibility of their longitudinal movement of the sliders with which they are connected U-shaped support post, pivotally mounted on the frame with the possibility of rotation in the longitudinal-vertical plane 2.

The design flaw is that. that the support post cannot move along its axis, i.e. perpendicular to the axis of the front strut of the undercarriage, which complicates the use of stakes during its transformation.

The purpose of the invention is to improve ease of use.

The goal is achieved in that the frame is made of two articulated interconnected U-shaped front and rear half-frames, each of which is pivotally connected to the respective posts with the possibility of rotation in the longitudinal-vertical plane, and the U-shaped support post is connected to the frames the possibility of fixing it in the required positions and the struts are perpendicular to the front struts of the chassis.

In FIG. 1 shows a ska with a box; in FIG. 2 the same in the seed position; in FIG. 3 - stowage in a folded position for storage or transportation; in FIG. 4 is a section AA in FIG. 1.

The baby wheel contains a chassis made in the form of a frame consisting of two U-shaped half-frames 1 and 2 pivotally connected to each other, carrying a box 3 and interacting with rear racks 4 and front racks 5 connected to each other, in the region of the lower ends which wheels 6 are installed on. The racks 5 are equipped with sliders 7 with locks 8 and 9 with the possibility of moving up the rack. The transverse strut 10 is pivotally connected at a point K by a spacer 11 with a rear strut 4 and to the slider 7 via an axis 12 with the possibility of rotation around a point K. At the bottom of the strut 5 are connected a strut 13. An adjustment washer 14 is installed between the struts 4 and 10. brackets 15 and

16 is connected via an axis 17 to the half-frame 1. The half-frame 2 is pivotally connected by the axes 18c with a U-shaped support

19, which is installed in the slider 7 so that its struts are perpendicular to the front struts 5 of the chassis, and is connected to the half-frames with the possibility of fixing in the required positions 5 using the latch 9. The upper ends of the racks 4 and 5 are pivotally mounted in the bracket 20 axes 21, 22. The handle 24 is pivotally mounted in the bracket 20 by the axis 23 and is fixed by a latch

0 25. The half-frame 1 has the ability to rotate around the axis 17. The half-frame 2 has the ability to rotate in the opposite direction about the axis 18. The strut 10 and the strut 19 are mounted perpendicular to the strut 5.

5 Half frames 1 and 2 are pivotally connected by an axis 26.

The device operates as follows.

In order to transform the frame colossally into the seed (summer) position, the box 3 is removed, the lock 9 is pressed, the rack 19 is lowered down along its axis to the stop on the slider 7. In this case, the half frame 1 rotates around the axis

17 to the side clockwise, and half frame 5 ka 2 around the descending axis 18 against

clockwise.

To transform the frame colossally into a reclining position: squeeze the lock 9, the rack 19 is lifted up along its axis

0 to a certain level, when half-frames 1 and 2 take the position of reclining and lower the latch 9.

To transform the frame to a position of transport or storage

5, the operations are repeated to transform the frame into the seed position, then release the latch 8. push the slider 7 up along the axis of the strut 5 to the bracket 20. At the same time, the rear strut 4 comes close to the front strut 5. The strut 10, rotating around point K and axis 12, the upper end approaches the upper end of the rear pillar 4. Half frames 1 and 2, rotating around the axes 17 and 18 in opposite directions,

5 approach each other. In the highest position, the slider 7 is fixed on the rack 5. Squeezing the latch 25 on the bracket

20. the handle 24, rotating around the axis 23, is brought closer to the front post 5. The released latch 25 prevents the handle 24 from oscillating, after lowering it to the lower position, the post 19 rests on the floor or is held in the hand for transportation
