    Abstract: A spiral staircase designed to be located adjacent a wall. The staircase has a spiral section which is composed of a successive series of horizontal, progressively angularly displaced steps that extend radially outwardly equal distances from and are connected at their inner ends to a common central vertical axial support so that the spiral thereby formed is circular in plan, occupies a minimum of space and has no central inner void. In order that the entrance to and exit from the spiral staircase be disposed in convenient locations, at least one of the extremities of the staircase constitutes a series of steps that extend rectilinearly in progression from the spiral, outside of the circular area thereof as viewed in plan and constitutes an access ramp that is disposed parallel to the wall adjacent which the staircase is located. the access ramp has structure connecting the ramp in a continuous and regular manner to the spiral section so as to constitute an organic and statically integrated assembly therewith.

    Abstract: AN ANNULAR COMPONENT SECURABLE TO THE END OF A TUBULAR ELEMENT OF A STABILIZING SPACER FOR THE STEPS OF A SPIRAL STAIRCASE. THE COMPONENT HAS A FIRST FLAT COLLAR TO WHICH A SECOND COLLAR IS WELDED AT TWO DIAMETRALLY OPPOSITE SPOTS. THE FIRST AND SECOND COLLARS HAVE EQUAL INSIDE DIAMETERS TO ALLOW FREE PASSAGE OF A STEP-SUPPORTING NEWEL. THE OUTSIDE DIAMETER OF THE SECOND COLLAR IS SLIGHTLY SMALLER THAN THE INSIDE DIAMETER OF THE TUBULAR ELEMENT TO PERMIT ENGAGEMENT WITH THE TUBULAR ELEMENT. THE SECOND COLLAR IS BENT AROUND THE DIAMETER EXTENDING THROUGH THE WELDING SPOTS TO PROGRESSIVELY DIVERGE FROM THE FIRST COLLAR AND INSERTABLE THE TUBULAR ELEMENT TO CENTER THE LATTER.
