Abstract:
The present invention provides a guard which is a surface that is adapted for mounting over the open end of the tread of a step of an open stairway such that when associated with a stairway: the exposed area of the OTEP is reduced. The present invention further provides for a retention means to maintain stable association of the guard with the stairway. The present invention further comprises kits comprising one or more guards, one or more retention means and instructions for use.

Claim (Index 1):
An apparatus adapted for use with an open stairway, the open stairway comprising a balustrade, the balustrade having an inner surface and an outer surface, the balustrade further comprising a handrail, the open stairway further comprising one more open end treads at least one of the open end treads having an open tread end protrusion (OTEP), the OTEP having an exposed upper surface, the apparatus comprising:\n (a) a guard configured for mounting to the open stairway, the guard having an upper edge, a lower edge, a leading edge and a trailing edge, wherein the guard is capable of being removed from the open stairway and does not comprise a structural element of the open stairway, and (b) a guard retention means, the guard retention means configured to maintain the upper edge of the guard in stable association with the outer surface of the balustrade of the open stairway, wherein the guard is maintained in stable association with the open stairway by employment of the guard retention means and the upper edge of the guard extends above the OTEP of least one tread and the lower edge of the guard extends below the OTEP of least one tread and such that an exposed upper surface of at least one the OTEP is reduced, and (c) a vertical drape, the vertical drape having an upper edge and a lower edge, wherein the vertical drape is capable of being removed from the open stairway and does not comprise a structural element of the open stairway, and (d) a vertical drape retention means, the vertical drape retention means being configured to maintain the upper edge of the vertical drape in stable association with the upper portion of the outer surface of the balustrade below the handrail of the open stairway and the lower edge of the vertical drape extending to a lower portion of the balustrade to at least the point of attachment of the upper edge of the guard to the balustrade such that when the vertical drape is in stable association with the balustrade by vertical drape retention means a portion of the outer surface of the balustrade is covered by the vertical drape, and (e) a handrail guard, the handrail guard configured for mounting to the open stairway, the guard having an upper edge, a lower edge, a leading edge and a trailing edge, wherein the handrail guard is capable of being removed from the open stairway and does not comprise a structural element of the open stairway, and (f) a handrail guard retention means, the guard retention means configured to maintain-the lower edge of the handrail guard in stable association with the outer surface of the balustrade of the open stairway, and the upper edge of the guard extends above the handrail and the lower edge of the guard extends below the handrail and such that external access to the handrail is reduced.
