Abstract: A kit of parts for securing a plurality of fixtures to an elongate support member is described. The kit of parts comprises a plurality of attachment members. Each attachment member comprises an aperture for receiving the elongate support member and a fixing detail adapted to attach a fixture to the attachment member. The aperture is larger than a lateral dimension of the elongate support member to provide a gap between the attachment member and elongate support member when received in the aperture. The kit of parts also comprises a plurality of locking elements. Each locking element is adapted to be received in the aperture in the gap between the attachment member and the elongate support member to secure the attachment member to the elongate support member by friction. Further, each attachment member is adapted to engage an adjacent attachment member when secured to the elongate support member by at least one said locking element to form a hollow column secured around the elongate support member for supporting a plurality of fixtures.

Abstract: A method of converting a traditional staircase into a dual-use staircase, for reducing the stepping height and knee stress in stairs climbing and descending, comprises: providing a plurality of lifting modules and a plurality of extending modules; connecting the plurality of lifting and extending modules in pairs to the original steps respectively; and optionally connecting a plurality of dividers in between said lifting and extending modules respectively.The dual-use staircase structure reduces the step rise by half, while keeping the total run about the same. It allows healthy people to walk in a full-step domain, while allowing people with knee concerns to walk on a half-step domain. The dual-use staircase may include dividers with lateral openings to facilitate reverse turning halfway during ascending or descending of the staircase.

Abstract: A ladder apparatus comprising a longitudinally elongated step support for mounting between an upper level and a lower level at a forward angle of inclination. The elongated support has an upper end and a lower end. A series of steps are mounted relative to the elongated support. A hinge assembly is mounted relative to the elongated support adjacent its upper end. The hinge assembly includes a pivot positioned adjacent one of the outer longitudinal edges enabling the ladder apparatus to be swung at least about 90.degree. between an operable position and a stowed position. The hinge assembly preferably comprises retaining means for inhibiting the ladder apparatus from swinging away from the operable position.

Abstract: A stair having a central stringer and two parallel side stringers. A plurality of vertically-spaced half treads is disposed on each side of the central stringer and extends between the central stringer and an adjacent side stringer. The half treads on one side of the central stringer alternate with those on the other side of the central stringer. The central stringer may or may not be a structural member depending upon the stair configuration but in all cases serves at least as a protective shielding of the inside corners of the treads, thereby minimizing user injury from the corners in case of a fall or other user mishap. A pair of handrails are disposed in a plane forward and parallel to a plane passing through the front edges of the treads and positioned with respect to the treads to provide support for a user.

Abstract: An adjustable step system for assisting a person walking up or down a flight of stairs. The system includes adjustable steps that can be mounted to the stairs of the flight of stairs. The adjustable steps effectively reduce the required vertical height of a step that a person is required to take for each stair. The adjustable steps are also movable and can be positioned at a desired location along the width of the stairs when not in use.

Abstract: A walking aid for old people or small children to help climbing or downing the stairs As a barrier free device is disclosed. It will help many old people or small children to use and step on this walking aid, more easy to climb and downing the stairs, safely. This walking aid is also an economical device, its material is mixed with wood and rubber that is available to made of reclaimed articles. The device further has a idea which is bright at night for a luminous paint. And Passengers can see the design of four leaves not to slip and fall in stepping on the stairs. Accordingly, this walking aid will be very convenient for an old people and a small child, and if we put on them on the stairs, it is beautiful just like blooming the flowers and comforting people's mind as present the heart of tenderness to such a weak people.

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.
