Abstract
A door holder includes an elongated housing which has at least one first fixing member which is located on the housing in correspondence with a desired open position of the door. An elongated guiding sleeve is movably mounted in the housing for movement lengthwise thereof in response to movement of the door. At least one second fixing member is movable together with the sleeve along the housing in response to movement of the door between the open and closed positions thereof. The second fixing member is movable between a first position in which it is disengaged from the first fixing member and a second position in which the second fixing member engages the first fixing member to thereby arrest the door in the open position thereof. The second fixing member does not have any direct contact with the elongated sleeve during movement thereof between the first and second positions.
