Patient support brake system

A movable patient support comprising:

• a frame;
• a patient support surface supported at said frame;
• a base supporting said frame and having a plurality of bearing assemblies for moving said base along a floor surface, said base including a head end base member, a foot end base member, and a longitudinal member extending between said head end base member and said foot end base member, said longitudinal member, said head end base member, and said foot end base member forming a base frame;
• a brake supported for movement between a non-braking position and a braking position for braking at least one bearing assembly of said bearing assemblies, each of said bearing assemblies having a mounting stem defining a swivel axis, said mounting stems mounting said brake assemblies to said base;
• a brake actuator for actuating said brake, and said actuator being at least partially enclosed by said longitudinal member;
• an annular member mounted about at least one stem of said stems of said bearing assemblies;
• and
• a locking member pivotally mounted at said base and being coupled to said brake actuator, said locking arm being moveable between an unlocked position and a locking position and moving to said locking position where said locking arm is engageable with said annular member to thereby lock said at least one stem from swiveling about said swivel axis when said brake actuator actuates said brake.

• a brake supported for movement between a non-braking position and a braking position for braking at least one bearing assembly of said bearing assemblies, said brake comprising an annular body extending around said swivel axis, and said annular body having a plurality of annularly spaced ridges having distal edges lying in spaced parallel planes, said ridges for engaging said at least one bearing assembly;
• and
• a brake actuator for actuating said brake wherein when said brake actuator is actuated said annular body moves toward said at least one bearing assembly and engages said bearing assembly with said ridges.
