Abstract
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.
Claims1
Hinge construction for doors or the like comprising first and second hinge parts adapted for mounting respectively on a stationary member and a movable member for hingedly mounting said movable member to said stationary member, said first hinge part comprising a first mounting flange, a first sleeve fixed to said first flange, and a hinge pin fixed within said first sleeve and protruding therefrom, said second hinge part comprising a second mounting flange having a rolled edge portion defining a second sleeve, said rolled edge portion terminating in a free edge adjacent the second flange for selective movement relative thereto and a resiliently resisted expansion of the second sleeve due to inherent resiliency of the material of the second hinge part, said second sleeve having opposed open end portions, said first and second sleeves being of substantially the same diameter with the second sleeve adapted to align over the first sleeve with the protruding pin received therein through a first end portion thereof, the second end portion of said second sleeve being internally threaded, a screw element threaded within the second end portion and defining a limit means to the insertion of the pin protruding from the first sleeve, said screw element being longitudinally adjustable within said second end to vary the degree of penetration of the pin into the second sleeve, said screw element being of a size relative to said second end portion as to effect a slight resilient expansion of the second end portion and a corresponding clamping of the screw element therein.
