Abstract

A children's folding wheel containing a frame with a decreasing width when folded, associated with a stiff back in the form of sections turning towards one another, struts connected to the front and rear wheels, and a rigid sectional seat with side rails, distinguished by that, in order to reduce the size when folded, the side rails are made in the form of armrests, hingedly connected by one side to the frame connected to the uprights of the rear wheels, and the other side to the posts of the front wheels that are The inner side is provided with braces that are hingedly connected to the seat sections, while the latter are hingedly connected to the frame in a transverse vertical plane and placed between the backrest sections. .15 SS (L to with SG1 00 00 77 Fig. 1

Description

The invention relates to non-rail sports equipment and can be used for walks with children and playing with toys.

The aim of the invention is to reduce the size when folded.

 FIG. Figure 1 shows the option of making a collapsible wheel with a decreasing 1-fold unfolded for use; in fig. 2 shows a schematic arrangement of the parts of said collier, side view; in fig. 3 - stake in nlan; in fig. 4 — fastening e.ment; in fig. 5 - - complex stake ska.

The wheel contains two flat longitudinal folding frames 1, including front wheel posts 2 and seat 3 connected by a rigid non-drying element and a rigid back 4 element by a rigid rear element 4. The rigid non-symmetrical element 3 of the seat 3 is dissected into separate parts 5, and parts 6 and the middle part 7. One with the other, the adjacent parts are connected using well-known P1 hinge elements, which provide their closing when folded and opened to the unfolded angle when unfolding the co; 1 ski. The non-average wheel racks 2 and nesup1, the seat element 3 is rotatably attached to the element 3. In addition to the front wheel racks 2, frames 1 include rear wheel racks 9 and sockets 2 and armrests 10, 1 pivotally connected with frame 1.

To the frames 1, the non-matching element of the seat 3 is attached with the Pommon, 10 fingers 11, npoBopachiuyu1.ihs in the wheel racks 2 and 9 by the middle of the axles 12. The non-suction element of the backrest 4 is attached to the frames 1 with 11 upwardinHH 13 and the glasses open to the bottom 14, which are provided with the extreme parts 6. The bottom of the cups 14 are rigidly attached to the edge of the handle 15, which are connected to the middle member of the handle 16 with QiapnnpoB, coaxially with the corresponding rigid nosnir joints of its backrest 4 element. By means of U-shaped connectors ene known devices for retaining it in the extreme positions, shock absorbers and brake, and rigid supporting elements of the seat and spin coated soft ki kami TUF (not shown). When folded koliki parts 6 and 7 of the rigid supporting element of the backrest 4 form food 18, i.e. Parts 6 and 7 limit the space in which I place 1 of part 5 of the rigid supporting element of the seat 3, just as the sheets of the raspol-1 book are in space, limited by its covers and cores.

The place of attachment of the upper ends of the braces 8 to the rigid carrier element of the side 3 is shifted backwards relative to the fingers 11. Therefore, when the pillars 2 are turned while folding the wheel, the braces 8 abut against the rigid carrier element of the seat 3. In addition, these attachment points are displaced inside the wheel relative to the planes of the side frames 1, with the result that when the pillars 2 are turned while folding the wheel, the braces 8 rotate the parts 5 upwards in the transverse vertical plane.

The finger 11 is provided with a pier 19, through

the axle 12 is lowered. On the axle 12, part 5 of the rigid bearing element of the seat 3 is rotatably fixed. Thus, the rigid bearing element of the seat 3 is connected to each of the wheel struts 2 and 9.

The stack is folded as follows.

By pressing a hand on one of the extreme parts of the handle 15, a gesture is folded forward — the bow of the backrest 4. The frames 1 are folded up, the feet 2 are turned around the fingers 11, the hard carrier of the seat 3 is approached, and pushes the braces 8, which act on the parts 5 of the rigid supporting element of the seat 3, turning them on the axes 12. This rotation is accompanied by the refraction of the rigid supporting element of the seat 3 and the rigid supporting element of the backrest 4 in Hiapnnpax, i.e. ck; Arranging frames occurs at the same time

0 reduction of 1niry clocks.

The hard, non-swayable element of the seat 3 and the hard carrier element of the backrest 4 vm are in one direction, and the rigid carrier element of the seat 3, as in a groove, is included in NIP1U 18, formed by a hard non-supersonic element of the snare 4. At the same time / The elements of the seat 3 and cnniiKii 4 stand out from the folded frames 1 in the same way as the bent lower ends of the rear axle: their wheel studs 9. Side fences of the seat

, -, made in the form of long wheel racks 2 and 9 and armrest 10. Connecting the pin with the pillars is hinged, which is the right side of the fence to have the smallest dimensions after folding.

For folding the pins bring together

5 rods of one of the frames 1. Thanks to the diagonals 8 this convergence is accompanied by a decrease in the width:

With fully folded frames, 1 of part 5 is interconnected with one another and located in nnnie formed by parts of 6

 - and 7. In this position, the collar is secured with a lock.

To decompose the collar for use, it is enough to release the latches and shake it, holding one of the outer parts of the handle 15. In this position, it is also locked with a retainer.
