<p>PROBLEM TO BE SOLVED: To provide a pull-in device unit capable of installing a pull-in device or a strike plate regardless of the thickness of a frame, and easily installing.SOLUTION: A pull-in device unit includes: a pull-in device 4 attached to a wall surface 1f on the opening-direction side of a hinged door 2 of an upper frame 1a of a frame 1; and a strike plate 6 attached to a wall surface 2a on the opening-direction side of the hinged door 2. The pull-in device 4 includes an arm 5 having a groove 5a to which the strike plate axis 7 of the strike plate 6 is detachably fitted. An arm 5 rotates around a vertical axis in a state that the strike plate axis 7 is fitted to the groove 5a when closing the hinged door 2 so as to apply torque in a closing direction of the hinged door 2, and detaches from the strike plate axis 7 when opening the hinged door 2. The arm 5 of the pull-in device 4 and the strike plate axis 7 are engaged with each other above the top face 2b of the hinged door 2.</p> |
