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.

A curved staircase including a double helix form with no center support column includes a plurality of stair segments, wherein each of the stair segments is formed from a plurality of rods coupled to a plurality of connecting nodes. The plurality of rods are arranged in a skewed tetrahedral geometry, which causes the plurality of stair segments to form a helical structure when the plurality of stair segments are coupled together. The plurality of rods form a spine on an underside of the plurality of stair segments. A tread is coupled to each of the stair segments. In alternate embodiments, the curved staircase may be formed from sheet metal creased to form a plurality of linear support locations and connecting nodes.

A swiveling staircase is provided for access to a device disposed above the ground at a distance that a person of an ordinary height is not able to reach. The staircase includes an immobile upright stanchion and a staircase assembly pivotally coupled to the stanchion. The staircase assembly includes a platform on the top of a plurality of stairs. The staircase assembly rotates between a first position where the staircase is docked out of way for storage and a second position where the staircase assembly is facing the front side of the device so that an operator standing on the platform may be able to reach the device.

A stairway apparatus for use with an endoscope storage cabinet includes a slidable door to open or close the cabinet's interior compartment. The stairway apparatus includes a base member disposed on a ground and placed against the cabinet, the base member having a first step with a front face, a rear face opposite the front face, and a top face connecting the front and rear faces, the front face having a lip coupled thereto and positioned to remain flush with the top face of the first step. The front face of the first step contacts front edges of the cabinet. The lip extends into the interior compartment of the cabinet when open and contacts side walls of the cabinet, thereby preventing lateral movement of the base member.

A module for a staircase can include a case configured to be installed on a front surface of a stair, a driving part located in an interior of the case, and a guide part driven in an upward/downward direction by the driving part to be located in the interior of the case or to be exposed to an outside of the case.

A simplified staircase 1 includes a plurality of girders 3 that form a plurality of steps Each of the girders 3 includes one or more first protrusions 17 that protrude from a front side of an upper surface of each of the girders 3. Each of the girders 3 further includes one or more second protrusions 15 that protrude from a rear side of the upper surface of the girder 3. The one or more second protrusions 15 are higher than the one or more first protrusions 17 in height.

Described is a component (1) for shelving, shelves, bookcases, stairs and similar furnishing elements which comprises at least two laminar elements (2, 2) substantially parallel to each other and which define a plane (P) of extension of the component (1).

These laminar elements (2, 2) are for covering an intermediate layer (3), interposed between them, substantially coplanar to the plane (P). The intermediate layer (3) has a frame consisting of metal crosspieces (3, 3) connected to each other by snap fitting means (32, 33). The frame is for supporting at least one elongate element (4), made of metal material, extending along a longitudinal direction (X) substantially normal relative to the plane (P) and in which they house induction lighting means (6). The elongate element (4) is positioned inside the perimeter defined by said frame. The metal crosspieces (3, 3) have ducts (31) for the passage of cables (7) for electrifying the lighting means (6).
