Abstract:
A locking mechanism for a vibration isolator on which a stretcher is to be placed, said locking mechanism being mountable on a movable frame of the vibration isolator and comprising:a stationary portion;a movable portion mounted on said stationary portion so as to undergo a rocking motion at least in a vertical direction;a first lock pin movable between a first lock pin locking position and a first lock pin locking release position;a second lock pin movable between a second lock pin locking position and a second lock pin locking release position;a link mechanism connected to said first and second lock pins; andan operation knob movable between an operation knob locking position and an operation knob locking release position for operating said first and second lock pins via said link mechanism;wherein said link mechanism is arranged such that, when said operation knob is moved from the operation knob locking release position to the operation knob locking position, said link mechanism moves said first and second lock pins toward the first and second lock pin locking positions, respectively, such that said first and second lock pins move toward each other to sandwich a portion of said stationary portion therebetween, thereby locking said movable portion with respect to said stationary portion.
