When hanging doors in a door-frame hinges are usually used consisting of two parts (1 and 7), one part (7) being fixed to the door-frame and provided with an upwardly directed pin (9) and the other part (1) being fixed to the door and provided with a sleeve (2) for threading over the pin (9). If an alarm arrangement is to be fitted, for instance, it is desirable to be able to accurately adjust the door in a vertical direction. According to the invention this is done with the help of the second part (1) of a hinge since its sleeve (2) is provided at the top end with a closure (4), the depth of penetration of this into the sleeve (2) being adjustable. |
