发明名称 Tripod with improved telescopic extension
摘要 The invention includes a base (21) provided with pairs of fitting hole (25), two each of which are spaced apart and situated facing each other so as to constitute a pair. A pair of rotary shaft portions (28) of each first leg member (27) are rotatably fitted in each pair of fitting holes (25). The two rotary shaft portions (28) are formed on the outer surface of the upper end portion of each first leg member (27) as an integral body therewith so as to extend coaxially. A second leg member (29) is inserted in each first leg member (27) in such a way that the distance by which the second leg member (29) projects from the first leg member (27) can be adjusted. As the top end face of each second leg member (29) can be positioned flush with the top end face of the associated first leg member (27), the invention is capable of improving the telescopic extension ratio of the legs.
