Abstract
A control device is pivotally connected with a lower frame assembly of a playpen. The control device has a pair of sleeves, a positioner, a resilient element, a push-button, a driving element, a string. Each of the pair of sleeves has a locking groove with a space for movably receiving the positioner and the resilient element. The positioner can be engaged with the locking groove to inhibit rotation between the pair of sleeves. The resilient element is positioned at one side of the positioner to bias the positioner, thereby keeping the playpen in an unfolded position. A push-button may be pushed to force the positioner to move against the biasing of the resilient element and enter one side of the pair of sleeves. The driving element is pivoted to one of the pair of sleeves to push the push-button. A user can rotate the driving element to push the push-button by pulling a string which is connected to one end of the driving element.
