Title:
COUPLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/053166
Kind Code:
A1
Abstract:
In a coupling device, in order to obtain a good attachment and detachment (removal) operability and simultaneously in order for an object to be attached to be reliably attached to a main body, a first engaging portion (14) and a second engaging portion (36) are formed on the main body (10) and the object (30) to be attached, wherein the first engaging portion (14) and the second engaging portion (36) can be displaced between a coupling position where the main body (10) and the attached object (30) are coupled and an uncoupling position where the coupling of the two is released and are engaged with and released from each other by this displacement. A lock member (58) is provided in the main body (10). The lock member (58) engages with the second engaging portion (36) to selectively prevent the second engaging portion (36) from moving with respect to the first engaging portion (14) from the coupling position to the uncoupling position. The lock member (58) is biased toward a lock position by a biasing means (66) and, by being pressed by the attached object (30), is displaced from the lock position to an unlock position while resisting the biasing force of the biasing means (66).
