ABSTRACT:
An improved brake structure for casters including a caster frame having a through pivot hole, two rollers mounted pivotally at the ends of the through pivot hole of the caster frame and having inner teeth, a rotary shaft pivotally mounted at a rear end of the caster frame to support an object such as a leg of a table or chair, a trigger element pivotally mounted at a front end of the caster frame, a first stop element for stopping the relative movement of the inner teeth of the rollers, a first spring element for urging the first stop element. The brake structure is characterized in that a second stop element is pivotally disposed below the trigger element and capable of horizontal displacement. The second stop element includes a front urging portion and a rear bent baffle wall. The trigger element further includes a trigger tab extending downwardly therefrom. When the trigger element deflects, the trigger tab will push the baffle wall. A second spring element is provided to urge against the second stop element. A stop ring is further provided at a rear end of the rotary shaft relative to the front end of the second stop element. The stop ring is provided with at least two notches at its outer periphery. The front urging end of the second stop element may engage the notches to achieve synchronous braking of the rollers and the rotary shaft.
