PROBLEM TO BE SOLVED: To provide a bed with casters capable of eliminating the necessity of a caregiver to go around the bed to lock/unlock the casters when the caregiver pushes and moves the bed, the operation states of two pedals provided on a pair of short sides of a bed frame being similar, and preventing the locked/unlocked state from being mistaken.SOLUTION: When the pedal 13b of bed leg side is pushed in downward, a lock link 11b1 and an interlocking link 15b1 swing clockwise around a rotary shaft 10b1. Then, a connectin rod 14 moves right, and the interlocking link 15a1 and the lock link 11a1 of a bed head side swing anticlockwise around the rotary shaft 10a1. Thus, casters 2 are locked, and the pedals 13a and 13b are both positioned downward.SELECTED DRAWING: Figure 3 |
