| 20120074290 | LEG DEVICE - A leg device that is capable of simultaneously releasing three extendible/contractible legs from a locked state with a single action is provided. A tripod, which is a leg device, has a base. A tripod head is attached to a tripod head attaching portion of the base. A middle extendible/contractible leg, a one-side extendible/contractible leg, and an opposite-side extendible/contractible kg are pivotally attached to a leg attaching portion of the base. Gripping all the three extendible/contractible legs, i.e. the middle extendible/contractible leg, the one-side extendible/contractible leg, and the opposite-side extendible/contractible kg, together causes the middle extendible/contractible leg, the one-side extendible/contractible leg, and the opposite-side extendible/contractible leg to simultaneously shift from a locked state to an unlocked state. | 03-29-2012 |
