术。
Description
本实用新型涉及一种智力玩具。
学龄前的幼儿怎样学习算术?一般情况下,都是家长教小孩数指头,数实物,或用笔写等等。这些,对幼儿的吸引力都不大。
本发明的目的是给幼儿提供一种趣味性较强的计算器。
本发明的目的是以如下方式完成的:外壳造型是个破壳而出的鸭子,鸭头可左右转动,蛋壳内装有齿轮、字盘和重块;计算时,转动鸭头,可从蛋壳的两个圆孔中找到从0到10所需要的加数和被加数,两数之和则在蛋壳的另一面圆孔中,平时不计算,可作“不倒翁”玩。
本发明的优点是能使幼儿在娱乐中学习简易的算术。
以下将结合附图对发明作进一步描述。
附图是本实用新型的正面示意图(局部剖面)。
参照附图,鸭头[1]下部是一根轴[2],该轴连接一大齿轮[6]和一大字盘[8],转动鸭头[1],大齿轮[6]与大字盘[8]也转动,带动右齿轮[13]和右字盘[11]转动,即可通过右孔[12]找到被加数[图中是2],接着,按下鸭头[1],即压下弹片[4],大齿轮[6]与右齿轮[13]分离,而与左齿轮[7]齿合,转动鸭头[1],即可通过左孔(图中已剖去)找到所需加数(图中是9),两数相加之和在蛋壳另一面的孔中(图中从略,应是11),目的是给幼儿一定的计算时间,然后再对答案。
图中,大齿轮[6]与小齿轮[7]或[13]的比为2:1。[3]是上蛋壳,[5]是左字盘,[9]是下蛋壳,[10]是重块,[14]是齿轮止点,齿轮转动一圈后必须反转。
