A handrail system that is constructed and arranged to be coupled to a stairwell such that at least a portion of a hand railing may be in an upright position or a lowered position. In an upright position, the system provides a complete top-to-bottom handrail. In the lowered, stowed position, the upper railing portion is conveniently stowed away within the stairwell. In a bulkhead embodiment, a full handrail is provided in the upright, use position and the upper railing is stowed within the bulkhead when the bulkhead doors are closed.

The present invention discloses a fully-assembled staircase system and an assembly method. The fully-assembled staircase system includes a stair slab, stair steps, stair stringers, landing slabs, steel connectors, and a stair handrail, where a main body of the stair slab is an inclined flat plate structure, lap joints are disposed at an upper end and a lower end of the stair slab LTB, an outer edge of an upper surface of the lap joint is provided with first grooves, one side of the landing slab PB is provided with second grooves, the stair stringer is an inverted T-shaped structure, a top surface of a web of the stair stringer is provided with third grooves, two flanges of the stair stringer are respectively fixedly lapped with the stair slab and the landing slab, the first groove, the third groove, and the second groove after the lapping jointly form a steel-connector groove.

A stair chair for use in transporting a patient in a seated position along stairs comprising a base, an upright coupled to the base, and a track assembly extending from the base for traversing stairs. A seat section is operatively attached to the upright and arranged for movement relative to the base between a plurality of vertical configurations including a first vertical configuration where the seat section is spaced from the base at a first distance for supporting the patient in the seated position, and a second vertical configuration where the seat section is spaced from the base at a second distance greater than the first distance. A lift mechanism is interposed between the base and the seat section to move the seat section between the plurality of vertical configurations. The lift mechanism moves the seat section to facilitate transitioning the patient to a standing position from the seated position.

The vertical fitness center stair tower system is an exercise device intended to provide users with an indoor climate-controlled stair tower, where they can obtain a cardio workout and lower body strengthen in comfort, away from the weather elements, (heat, rain, snow and cold weather) and exercise in a safe facility away from the harm of motor vehicles. Accordingly, the system comprises a tower structure with multiple floors, multiple staircases connecting each floor, and convenient interconnecting landings. Further, the system comprises multiple electric, electronic, entertainment, and HVAC systems that enable users to have a comfortable and enjoyable work out session. Furthermore, a security system with emergency buttons, and a plurality of lighting devices integrated into the tower structure, projects a safe workout place. Thus, the device provides a safe, well lit, less traffic, and comfortable environment in the vertical exercise system.

A freestanding, adjustable, modular spiral staircase embodied in a unique method of spiral staircase design is provided. The steps of the spiral staircase are arrayed and supported in a circular pattern around a central column with the outside edges or leading or trailing corners of the steps are supported by three peripheral columns, while step posts interconnect adjacent steps. Many parts are interchangeable and the steps adjustable to allow for shortening or lengthening the staircase. The base of the staircase unit is heavy to provide maximum stability and to prevent tipping.

Described herein are systems and methods of manufacturing a spiral staircase assembly for custom projects. A method may include coupling a plurality of stairs to a center column such that distances between adjacent stairs of the plurality of stairs deviates less than ½″ to meet code. A method may further include cutting the center column after coupling the plurality of stairs to the center column to form a first center column and a second center column. A method may further include welding a female column coupling to a first end of the first center column and welding a male column coupling to a first end of the second center column. The male column coupling is configured to couple to the female column coupling such that when the male column coupling is coupled to the female column coupling, distances between adjacent stairs of the plurality of stairs deviates less than ½″.

A mid-rise residential building with a garage section, a lower section disposed above the garage section, and an upper section disposed above the lower section is disclosed. The upper section includes a corridor that traverses the building, but the lower section does not include such a corridor. The garage section includes a plurality of private garages. The lower section includes at least a pair of multistory dwelling units, where each unit has a through unit floor plan and each unit provides direct access to a respective private garage. The upper section includes a corridor. The upper section also includes a single story dwelling unit that is primarily accessible from the corridor; and at least two multistory dwelling units that have respective entranceways disposed laterally across the corridor from the single story dwelling unit. Each of the multistory dwelling units has a second floor with portions directly above the corridor and the single story dwelling unit. An elevator serves the corridor of the upper section, but it bypasses the lower section.
