Abstract
A pivotal device for a playpen includes a connecting member which pivotally connects two siderails of the playpen. Each of the siderails has a spring received therein which has a protrusion extending through the siderail and the connecting member and a pushing end being accessed via a hole of the connecting member. An operation plate mounted to the connecting member with a slidable member biasedly disposed therebetween. The operation plate has flexible plate and a head with a tapered surface extends laterally from the flexible plate, the slidable member having one end thereof slidably located below the head so that when the slidable member is shifted, the head is pushed to push the pushing ends of the springs to withdraw the protrusions from the connecting member to allow the siderails to be pivoted.
