PIN CONNECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/088674
Kind Code:
A1
Abstract:
[PROBLEMS] To realize improvement in assemblability and a reduction in cost
by facilitating the assembling of a pin guide member holding a pair of connection
pins. [MEANS FOR SOLVING THE PROBLEMS] Outer brackets (15, 17) are stacked on
inner brackets (16, 18), and pins (22, 23) are inserted into the pin holes (19,
20) of the brackets to connect the brackets to each other. The inner flange parts
(38, 38) of the pin guide members (37, 37) holding the pins (22, 23) are integrally
joined to each other through support plates (40) as connection members by bolts
(41) and nuts (42). The outer flange parts (39, 39) of the both pin guide members
(37, 37) are supported on the inner brackets (16, 18) in the radial direction of
the pins and locked to prevent them from rotating.
