| 摘要 | PURPOSE:To enable the easy positioning and fixing of a berth by adding the function of locking the turn and rotation of turnable and rotatable casters provided in the part of the berth, respectively. CONSTITUTION:When a locking pedal 2 fitted to the end of a shaft 2a is pushed down to rotate at an angle of 90 degrees by a foot, the part of a tightening means 7b on the free side is moved to narrow the aperture of a cut part 7e by screwing, since the part of said means on the double nut 7f side is fixed, and when the aperture (d) is reduced to nothing, a sprocket 7a is locked to stop its rotation by the tightening means 7b. By this setting, front wheels 3 are locked to stop their turn when the sprocket 7a is locked. Accordingly, when the locking pedal 2 is pushed down at an angle of 90 degrees to be raised in the reverse direction, the aperture (d) appears again, and the sprocket 7a is returned to the state of free rotation. Thus, the front wheels 3 is unlocked so that it can turn. | ||||||
