Document Type and Number:
WIPO Patent Application WO/2014/171216
Kind Code:
A1
Abstract:
A coupling device (10) which is coupled with a coupling arm (7) has vertically arranged first and second coupling sections (20), a coupling rod (30), first and second arm receiving sections (26), and a rod holding section (26b). The first and second arm receiving sections (26) are coupled by a link member (40). When the first arm receiving section (26) is located at a standby position, the rod holding section (26b) supports, within a first guide space (K), the lower end of the coupling rod (30). The first and second arm receiving sections (26) are pressed by the connection arm (7), which is inserted into a second guide space (K), and pivot from the standby position. The rod holding section (26b) pivots together with the first arm receiving section (26), thereby permitting the coupling rod (30) to move so that the coupling rod (30) is inserted through a second through-hole (H), and permitting the coupling rod (30) to be coupled with the coupling arm (7) inserted into the first guide space (K) or the second guide space (K).
