Abstract:
A door guard comprising:a retaining member fixed to a body; a pivotal lever whose basal end portion is pivotably supported by a door; position restricting means including biasing means, said position restricting means restraining said pivotal lever both in a lock position and in a release position with predetermined amounts of force exerted by said biasing means, said biasing means biasing said pivotal lever such that said pivotal lever returns to the lock position within a range of return angles from the lock position; forced pivoting means, when said door is swung from the closed position to the open position in a state in which said pivotal lever is pivoted to the lock position, said forced pivoting means pivoting said pivotal lever within the range of return angles from the lock position against the biasing force of said biasing means as said door is swung open from a closed position and when said door reaches a particular half-open position, said forced pivoting means allowing said pivotal lever to pivot back toward the lock position by the biasing force of said biasing means; and said retaining member being formed with an engagement portion, so that when said pivotal lever, which has been pivoted from the lock position by said forced pivoting means, is pivoted back toward the lock position by said biasing means, said engagement portion is brought into engagement with said pivotal lever to prevent said pivotal lever from moving in a swinging direction of said door.
