下雨时,往往伴有较大的风。现在人们使用的伞,一般都不抗风。在较大的风中打伞,伞面常被刮得向上翻,影响正常使用。为了克服这个缺点,我设计制作了一种抗风伞。这种抗风伞是在原伞活动支撑骨架的基础上,添加几根软绳,如图1所示。1.水平拉线,沿伞的直径拴一条结实的软绳。 图12 When it rains, it is often accompanied by greater winds. Umbrellas that people use today are generally not resistant to wind. In large winds, umbrellas are often scraped upwards and affect normal use. In order to overcome this shortcoming, I designed and manufactured an anti-wind umbrella. This anti-wind umbrella is based on the original umbrella activity support skeleton, add a few soft ropes, as shown in Figure 1. 1. Stretch the cable horizontally and draw a strong cord along the diameter of the umbrella. Figure 12
