Claims

[Claims for Utility Model Registration] In a support lock mechanism for a unit 1 which is rotatably supported around a point 2 on a machine frame 3 of a machine body and is to be selectively fixed at a plurality of rotational positions, A first arm 4 swings around a point 7 on the frame that is away from the rotation center 2 of the unit, one end of which is pin-coupled to a point 8 on the unit 1 that is away from the rotation center 2. , a second arm 5 whose other end is pin-coupled to one end 6 of the first arm 4, and the sum of the distances between the supporting points at both ends of the first arm 4 and the second arm 5 is defined as The fulcrum 7 on the machine frame side of the first arm 4 and the fulcrum 8 on the unit side of the second arm 5 when the unit occupies a plurality of predetermined rotational positions.
At the junction of the first and second arms, one arm has a fan-shaped part 4-4 centered at the connection point 6, and the unit 1 is fixed. When the other arm reaches each rotational position, the approximate center line of the other arm is aligned with the arcuate edge 4- of the fan-shaped portion.
Notch grooves 4-2 and 4-3 are provided at the points where they intersect with 1, and the other arm has grooves that can be fitted into the notch grooves 4-2 and 4-3 approximately on the center line thereof, and in the direction of engagement. A support lock mechanism characterized in that a biased lock pin 9 is provided, and manual release means 11, 14 are provided for releasing the lock pin against the bias force in the fitting direction.
