A security device for mounting to a door, the device having a floor-contacting member to prevent the door from being forced open when the device is engaged. The device is slidably and pivotably mounted to the face of the door so as to be engageable and disengageable with one hand without excessive bending or stooping. When not in use, the device stores flush against the lower portion of the door.

A security device for mounting to the inside face of a door to engage the floor to prevent the door from being opened, comprising: a shaft; shaft mounting means mounted to the face of the door for slidably and pivotably mounting the upper end of said shaft such that the shaft can slide vertically within upper and lower limits and pivot relative to the door; a control rod; shaft slide means mounted to said shaft at an intermediate point for pivotably and slidably mounting a first end of said control rod such that said control rod can pivot and slide within upper and lower limits substantially parallel to the longitudinal axis of said shaft; control rod mounting means for pivotably mounting a second end of said control rod to the door such that the first end of said control rod bears against the upper limit of said shaft slide means when the upper end of said shaft is substantially at the upper limit of said shaft mounting means; means for urging the portion of said shaft below said shaft slide means downwardly and toward the face of the door; whereby said security device is extendable to engage the floor by rotating said shaft about its upper end, said urging means urging said shaft downwardly so that said upper end of said shaft slides downwardly within its mounting means, and said urging means initially urging the first end of said control rod against said upper limit of said shaft slide means to support said intermediate point of said shaft against downward motion, and subsequently urging the first end of said control rod toward said lower limit of said shaft slide means to permit said intermediate point of said shaft to move downwardly, thereby bringing the lower end of said shaft into contact with the floor.
