A door holder includes a rail (1) which has a longitudinally extending slot (10) for movement of a slide body (11) relative to the rail. The slide body is pivotally connected to one end (21) of a holder rod (2), the other end (22) of which is pivotally fastened to a door frame. As the door is opened and closed, the slide body (11) is moved from a first position (a), in which the door is closed, to a second position (b), in which the door is open, or vice versa. In the second position (b), the rail (1) provides a narrower free passage for the slide body (11) than at the first position (a) so that as the door opens the side body (11) will slide easily in the rail (1) until it reaches said second position (b), at which the door is braked as a result of the narrower free passage provided by the rail, while successively increasing resistance to movement of the slide body (11) in the rail (1). |
