Description

The invention relates to the field of transport engineering, namely, recreational baby strollers.

A known baby carriage containing a uniaxial chassis, on which 5 is fixed, equipped with a seat and a U-shaped footboard, a frame that carries a back and an L-shaped handle, made in the form of a tubular frame [].

This device is the closest to the invention in its technical essence and the achieved result.

The disadvantage of the stroller is that it cannot be used 15 as a chair and a folding bed.

The purpose of the invention is to expand the functionality of the stroller by using it as a 20 chair and a folding bed.

For this, the frame is made of three tiers, formed by horizontal rails attached to the front and rear pillars of the carcass, 25 rails of the lower tier are equipped with backward-facing consoles with latches for interaction with the chassis and rod support for interaction with the U-shaped cross bar 30

steps, while on the middle tier there is an axis of the footrest, sitting and at the intersection of the latter with the rear pillars of the frame is a hinge for turning the backrest, having a lock for holding the latter in a vertical position and an additional latch for fixing the handle, the upper ends of the handle are bent and length they are equal to the distance between the lower and middle tiers.

Pushchair 1 comprises a uniaxial chassis on which is mounted a seat 2 equipped with frame 3, .posuschey backrest 4. The carriage also comprises _a footboard 5, support rod 6 and handle 7.

The frame 3 contains three horizontal tiers 8-10, connected by the front 11 and rear 12 pillars. The bottom tier 10 has a rearward-facing console /

13 (see Figs. 3, 7) with latches 14 and holes a placed in them for mounting bent ends 15 of rod support 6 in them. On the middle tier 9 there is a seat 2, an axis of the running board 16 and at the intersection of the middle tier 9 with the rear a pair of racks 12charnir 17 backrest 4.

The back 4 is made in the form of a flat tubular frame and consists of two vertical pipes 18 (see Fig. 4) and horizontal jumpers 19. The vertical pipes have arms 20 (see Fig. 5) with spring latches 14 placed in them. To the frame the backrest is attached a pillow 21 (see Fig. 1). The back ^ mounted on the hinges 17 is held in a vertical position by retainers made in the form of U-shaped brackets 22 (see Fig. 4,6) hinged on the backrest 18 vertical pipes 4. and fixed by two spring-loaded latches 14 built into the pipes in two positions

(see Fig. 4), in one of which they cover the rear pillars'

12 of the frame 3. The consoles 20 of the split and the lower belt 10 are closed by decorative plugs 23 (see Fig. 3 and 5)

Uniaxial chassis 1 and handle 7, made in the form of an L-shaped tubular frame, are worn with their sleeve ends, respectively, on the console 13 of the lower belt of the frame and the console 20 of the backrest frame and are held in place by latches 14.

The l-shaped frame of the handle 7 has the same sleeve ends and can be mounted on the console 20 with either end. The length of the short ends of the handle is equal to the distance between the lower Yu and the middle 9 tiers of the frame 3 and therefore the handle 7, wearing long ends on the arm 20 of the backrest 4, folded back to a horizontal position, creates a support for it with the height of the back cushion 21 from the ground equal to the seat height 2 ( see Fig.8), and wearing short ends on the same console - serves as a handle for moving the stroller (see Fig. 1) or the awning over the seat (see Fig. 7).

The footboard 5 is made in the form of a Pruchnoy 'tubular frame with jumpers 24 (see Fig. 2) and is mounted on the hinge 16 of the middle tier 9 of the frame 3. Core support 6, the bent ends 15 of which enter the holes of the lower tier 10 of the frame 3, holds the steps up 5 at different heights, resting its limb 25 (see Fig. 2) in one of its jumpers 24.

When using a stroller for its intended purpose, the zooka 7 is mounted with short runners on the backrest console 20 with the direction of long ends. back, the hub ends of the chassis 1 are put on the console 13 of the lower tier 9 of the frame 3, and the step 5 is fixed by the rod support 6 in the position providing the child’s foot to the g surface (Fig. 2) of the step.

To use the baby stroller as a chair, they remove the uniaxial chassis 1 and handle 7 by alternately pressing the corresponding latches 14, release the core support'6 under the leg 5 and place the chair on the floor with the lower tier 10.

When using the stroller as a child seat with an awning, similarly remove the chassis 1 and * release step 5 from the rod support b, move the handle 7, directing its long ends forward over the seat and set the chair with the awning on the ground with the lower belt of the frame 3.

To get a folding bed on the console 20 of the backrest 4, we put on the ends of the handle 7 with the direction of its short ends back, release the back from the latches, pressing the latches 14 and turning the U-bridges 22 until they are fixed in position 6, fold the back back to the horizontal position and set the cot bed on the floor, based on the lower tier 9 of the frame 3 and the short ends of the handle 7.
