Perhaps, in the memories of every adult baby winter fun be sure to contact the sled. And it’s safe to say that in a rare home today will not meet them: they still serve the kids and adults — the baby in daycare to take a little weight out of the house or building to deliver in the snow.
And despite the variety of designs, this simple technique has a lot in common, well-established and traditional in execution and use. For example, as a rule, they move with a flexible leash rope belt. This is inconvenient, because the sleds are always pulling back. If he’s moving fast, the snow Shoe gets in the sleigh, in addition, have alternately look either forward or backward, and because of the lack of strict control of the sled can tip over.
There are, however, constructions with a rigid arm, secured the rear. It’s much easier: the movement occurs, more stable, lighter and more confident to overcome obstacles. However, it is not without flaw: when pushing the back can not see the face of the passenger. Remember these inconveniences for the future of our reflection, and yet consider the requirements for the sled to ride from the mountains.
This calls for a different design — without backrest and handrails: because to race with the slides lying on the sled on his stomach. In this position and a low centre of gravity, air resistance decreases, and thus increases the speed. And close to the snow flying from under the runners of the sled, acute emotional perception.
All of these conditions can be implemented by introducing simple design changes in the sled.
