    Abstract: A telescopic and retractable bleacher system and handrail that stows with the bleacher system. The bleacher system is adapted to move between an open position in which seating is available for use and a closed position in which rows of seating surfaces are vertically stacked. The system includes handrails adapted to move between a use position when the system is in the open position and a stowed position when the system is in a closed position. A post of the handrail includes a cam and a cylinder surrounding the post includes a cam slot. A ramp on a surface of the aisle step engages the post and raises the post within the cylinder as the bleacher system is moved into the open position. As the post is raised in the cylinder, the corresponding cam and cam slot cause rotation of the post.

  • Patent number: 8966859
    Abstract: A staircase and method for producing the same. The staircase is produced by double routing channels for sub-treads and sub-risers and capping risers and capping treads. These sub-treads and sub-risers are assembled into staircase stringers that have pre-routed channels that are sufficient to install sub-treads and sub-risers having a particular thickness and having room for subsequent placement or installation of capping treads and risers by sliding them laterally into the channels created by the double routing of the stringers. This creates a more finished look to be (the) staircase while avoiding damages to the capping treads and risers that might occur during building construction.

  • Publication number: 20150047273
    Abstract: A system and method for establishing a safe room environment within an attic space utilizing a typical folding attic stair and door assembly. The system includes components that retrofit to an existing folding attic stair in a manner that allows the user to draw the attic stair up behind them and to secure the attic door panel closed and locked while the user is within the attic space. The components include a retractable lift cord attached to a middle section of the attic stair, and a lift rod attached to the attic door. Brackets and frames positioned on the attic door and door frame allow the user to pull up to fold and raise the stair into the attic space. A lock may then secure the attic stair closed preventing access from below. Methods for installing the system and using the system are provided.

  • Patent number: 8307603
    Abstract: Methods and tooling for constructing a stair unit are provided. The methods incorporate tooling and tables to create templates (two for each tread) that, when laid along a series of hypotenuse marks on the stringer from the table, will dictate the geometry, cutting, and fitting to the treads, without using a framing square. Brackets are used to conjoin the stringer, tread material, and tread framing so that the tread width is not limited by the lack of strength of the tread material. The methods then incorporate the bracket in a tread module to provide further convenience and sequencing options for the assembly of the stair unit. An alternate method combines aspects of the template and the bracket to hold continuous support for the tread, accomplishing a cut stringer look. The result is less time and material expense with better strength, fit and finish.

  • Patent number: 8112965
    Abstract: The assembly and method of the present invention is used for forming a monolithic tiered concrete slab or stairway. The assembly includes a plurality of foam blocks positioned adjacent one another and in a plurality of rows on a support base. The upper surfaces of the blocks are sloped and form a continuous included plane from the front row to the back row. Interface elements are attached to the upper surfaces so as to cover the joints between adjacent blocks. Riser ties are mounted on the interface elements, with riser face forms attached to the ties. After the blocks are positioned and the interface elements with riser ties and face forms assembled, concrete is poured under the blocks so as to cover the upper surface, the interface elements, and the ties, thereby forming a monolithic tiered series of risers and treads.

  • Publication number: 20110271612
    Abstract: A stairway assembly includes a tread and riser panel attached together by a uniquely designed gusset to form a tread and riser assembly that can be integrally installed on the stringers. In one embodiment, a first portion of the gusset includes a first attachment structure connected to the lower surface of the tread, and a second portion of the gusset has a second attachment structure connected to the lower surface of the riser. The first portion of the gusset extends at an angle from the second portion, with the side edge of the riser overlapping and facing the upper surface of the tread, and said tread side edge faces said gusset. The gusset may include an elongated slot that forms a line of weakening in the gusset. The gusset may be bent about the line of weakening to move the tread and riser into the final position in which the tread is perpendicular to the riser.

  • Publication number: 20110232214
    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.
