Introduction Of Slide
Introduction of slide
Slides are integrated sports equipment, only through climbing to slide activities. Children playing slides need a firm will and confidence that can foster their bravery. When the child "wind" to slide down, can enjoy the joy of success. The slides are one of the children's sports equipment,
Common in kindergartens or children's playground, generally suitable for children 3-6 years old, there are also special-purpose slides, such as life-saving slides and so on. The slide is fitted with ladder on one side of the shelf and the other side is fitted with a sloping skateboard (usually flat and curved). The child slides up from the ladder and slides down from the swash plate.
Slide type (1) a kind of children's sports equipment, common in kindergarten or children's playground, generally suitable for children 3-6 years old. (2) special purpose slides such as slides for life saving.
Slide can be done by climbing. Children playing slides need a firm will and confidence that can foster children's bravery. In the game can enjoy the joy of success.
Slide by the climbing section, platform section and the lower section of the composition, the general use of wood, stainless steel, artificial terrazzo, glass fiber, reinforced plastic production, to ensure smooth skateboard surface. Slide in size to follow the ergonomic principles, and the body with a high degree of cooperation with children's age and size, in order to benefit their healthy growth. Generally in the design, the slide climbing ladder angle of about 70 °, width 40cm, ladder plate 6cm high, armed with railings on both sides. Skateboard inclination 30 ° -35 °, width 40cm, both sides of the straight edge of 18cm, easy to children's feet brake. In addition, the finished skateboard and homemade slides should be in the lower part of the pavement thickness of not less than 3cm of the pad, or more than 40cm of sand, to prevent children from falling injuries.  and pay attention to the slid of the endurance, cushioning force, both sides of the handrails, and whether the width is appropriate, parabolic is not reasonable, the best way is to practice, refer to other finished products, The first one. Principle of the principle of the most speed curve. There are two kinds of slide skateboard, one is straight, there is a kind of bending, and its sliding surface is the wheel line. Assuming the height of the two slides, there are two children with exactly the same weight, respectively, from the vertex of the slide at the same time, the first to reach the ground is not a straight skateboard on the children, but the spin wheel slip on the surface of the children. Because the child is able to slide on the slide, because of the role of gravity. The magnitude of the gravitational force is also different when the slope of the skateboard is different in the descending direction. The greater the gravity component, the greater the acceleration of the descent, the faster the speed increases. As the straight slides slide down, the acceleration of the descent remains constant and the speed increases steadily. The slides along the sprocket slides, and the slippery of the beginning of the slide is so large that the descending speed of the descending child is very large in a very short time. Although, in the second half of the decline, the slope gradually becomes smaller, the speed increase slows down, but the speed of decline at this time has become very large. As a result, the average speed of the slide along the wheel line slides down throughout the downtime. Even if the length of the skateboard slide is longer than the length of the straight slider, the time to slide along the pulley slide is shorter than that of the straight slide. This is proved mathematically and physically. That is, under the same height of the same conditions, along the rotation of the wheel line the shortest time.
For the growth of the children, the game and learning is essential to provide some good game opportunities and the environment is the most direct way to make them in the first stage of life to achieve the basic purpose of the game and learning. Through the game, the children can not only exercise physical fitness, develop sports skills, increase balance and coordination, but also in the process of social activities can learn to interact, stimulate potential, improve cognitive ability and language skills. As the saying goes: "seven sitting, eight climb", when your baby will play later, in the spring season, Mom and Dad can bring your baby to children's paradise. On the one hand to exercise the baby's body, to improve their ability to exercise; the other hand, let the baby observe the activities of the children to stimulate the baby to play slides desire. Here are a few ways:
1, with the help of adults slide: When the baby can stand firm, Mom and Dad can take the baby to play the slide. Father or mother holding the baby sitting on the slide, his hands in the arm under the arm from the top down, his mouth said: "When the baby played a few times, with experience, father and mother only need to baby On the slide, my mother squatted at the bottom of the slide, my father stood next to the slide care baby, let the baby slide down.
2, the baby can be staggered to walk when the father and mother can take the baby to play low, gentle slides. Mom hands in the arms of the baby, to help the baby climbing to the top of the slide to encourage the baby to slide down (Mom and Dad can not be forced to hold the baby, slide before checking the slide on both sides is smooth, whether there are stains). 3, the baby independent play slide: When the baby can play tall slide, let the baby climb the slide, and then slide down. 4, and companions play slides: Mom and Dad to bring their children to children's playground with small partners to play slides, guide the baby to take the initiative to communicate with peers, cultivate the quality of the baby humility. Can also be used to encourage the language of the baby: "baby good, let the little brother first play, okay?" If the baby in the performance with the companion slide slide is particularly good, Mom and Dad can give the baby appropriate encouragement.
