<p>A handrail is linked to a banister stave on a building's stairs by using a high-strength screw (3) with first (6) and second (7) threaded sections spaced apart on a screw shank with a screw head (4). The first threaded section is braced in a first functional element (1,1a) and the second threaded section removed further from the screw head is braced in a second functional element (2). An independent claim is also included for a building's internal stairs with a handrail and banister staves linked to it.</p> |
