The invention relates to snowmobile vehicles, in particular, to folding children's san.

The purpose of the invention is to expand the functionality by operating in the folded position.

Fig. I shows a sleigh, front view; figure 2 - section aa in figure 1 on fig.Z sleigh in the folded position, a longitudinal section; figure 4 - node 1 in figure 1; on fig.Z - section bb in figure 2; FIG. 6 shows the node P in FIG. 2; figure 7 - node W on fig.Z; in fig. 8 is a view of In figure 2.

Folding sleds include a skid 1 with a step 2, a front 3 and a rear 4 pillars, a stitch 5, a handle 6 rigidly connected to the back 7, a hard seat 8, elastic clamps in the form of a spring 9 and a clamp in the form of a latch 10. At the same time 1 is fixedly attached to the substrate 2, made in the form of an L-shaped plate to increase the sledge’s passage through the snow and to protect the child’s feet from it. Front pillars 3 form coaxially hinged joints with runners 1. Similarly, 1 rear pillars 4 are connected in a similar manner to the runners. In the plane of the runners 1, front 3 and rear 4 pillars are pivotally connected to the ends of the strings 5 by coaxial hinges formed by transverse rods 11 and 12. The rod 12 is simultaneously the axis of the articulated joint of the middle part of the handle 6 with the back 7 with the rear legs 4, the lower part of the handle 6 with the back 7 connected with the transverse rod 13, which extends into the open transverse grooves coaxially made in the runner x 1. The handle 6, entering the groove runners 1, the rear posts 4 and the runners 1 in the longitudinal direction form a closed kinematic purpose and provide vertical stiffness and the longitudinal sledge frame. The handle 6 is pivotally connected by a rod 14 to the edge of the seat 8. The other edge of the seat 8 rests freely on the rod 11 of the front pillar 3. The slider 1 with the footboard 2, rigidly connected with rivets 15 and 16, are connected by tension springs 9 with the front pillars 3. On The bottom surface of the seat 8 is fitted with a locking device 10. The grooves in the runner x of the locking rods 13 are made for the purpose of greater manufacturability of the runners 1 in the patch plates 17

fixedly attached to the colostomy with 1 rivets; 18 (figure 4). To ensure the insertion of the rods 13 into the grooves of the plate 17 of the runners 1, they are made in

 upward slots, the back side of which is higher than the front. The axles of the articulated joints of the front 3 and rear 4 racks with the runners 1 are rivets 19. The ends of the rods 11 and 12, missed

through the links, have a diameter smaller than the diameter of the rest of the rod, and flared at the ends. All axle joints are worn on

washers 20. Fixed mounting of the backrest 7 to the handle 6 is carried out by covering the rod 12 with clamps 21 with rivets 22 (Fig. 8), and the rod 14 with loops 23 with rivets 24 (Fig. 6).

The hinged seat 8 to the handle 6 by the rod 14 is carried out by covering the latter with loops 25, located between loops 23, with rivets 26 (Fig. 6). Spring 9 one

the end clings to the protrusion on the bracket 27 fixedly attached to the A-pillar 3 by rivets 28, and the other end to the similar protrusion on the step 2. The protrusion is a rivet 29 with the sleeve 30 and the washer 31 (, FIG. 5). The end sections of the rod 13 are similar to the end sections of the rods 11 and 12, they are equipped with sleeves 32 and washers

33, fixed on the rod 13 by its flared ends (FIG. 4). The latch 10 consists of a spring-loaded lock 34 of the lock 35 having a longitudinal groove sliding along the guide lugs formed by the rivets. 36 with bushings 37 and washers 38 arranged on a bracket 39 supporting the lock 35, which is fixed to seat 8 (FIG. 7).

Enough for the warehouse

pull the handle 6 up until the rod 13 exits the grooves of the plate 17 and rotate clockwise around the axis of the rod 12 until the handle 13 of the handle 6 is fixed by the latch 10, then allow the springs 9. to bring the sledge to the folded position. From turning the handle 6 with the back 7 and the seat 8 around the axis of the rod 12, on the one hand limits the support of the seat 8 to the footrest 2, and on the other, the stop of the ends of the rod 13 in sheath 5 (FIG. 3). B folded position handle 6, back

7 and the seat 8 form a rigid frame resting on the front of the runners 1 and the rear legs 4, thereby being converted into other sleds, which can be used as a vehicle.

The proposed sleighs are related to consumer goods, and their use will allow for maintaining the child’s correct posture. facilitate the transport of sleds in vehicles and their storage. An additional positive effect can be obtained from the use of the folded sled as a vehicle.
