任何一种类型的折叠家具,要想折叠灵活,运用自如,符合人体使用功能要求,其折动点位置的确定是一关键。在这以前,设计者多数采用作图法来确定折动点的位置,或者通过试验最后定位,而很少利用解析法来求得。作图法在某种程度上有其优点,它比较简单,是行之有效的。钢管折椅折叠形式多样,是折叠家具中造型比较复杂的一种。我厂生产钢管折椅已有近廿年的历史,曾用作图法设计了很多种钢管折椅,其结构、花色品种在国内外市场上享有一定的声誉。但至今没有用解析法求出折动点的具体定位尺寸。
Any kind of folding furniture, in order to fold flexible, easy to use, in line with human functional requirements, the location of the folding point is a key. Prior to this, most designers use the mapping method to determine the location of the folding point, or by the final positioning of the test, and rarely use analytic method to get. The drawing method has its advantages to some extent. It is relatively simple and effective. Folding folding steel pipe folding in various forms, folding furniture in the more complex shape. Our factory has nearly 20 years of history in the production of steel tube folding chairs. We have designed many kinds of steel tube folding chairs for illustration, and its structure and color varieties enjoy a certain reputation in domestic and overseas markets. But so far there is no analytic method to find the specific positioning of the turning point size.
