Abstract

A door stay for attachment to a door above a floor, the door stay comprising a mounting means, and a floor-contacting element rotatably mounted on said mounting means, the floor-contacting element being biased against said floor by the mounting means. Preferably, the floor-contacting element is a ball and the ball moves over the floor under tension. The door stay provides significant advantages in the positioning of a door so that it will not swing to and fro, but which can still nevertheless be swung open when desired by manual operation of the door. The door stay is attachable to the lower edge of the door, wherever required and removed when no longer required, or when it is required somewhere else. All of these features are provided in a relatively simple low cost door stay which is highly effective in practical use.
