Patent number: 7082725Abstract: In recent decades within the building industry, there has been a trend toward mass production of building components. The trend has included every part of structures except for the concrete slab the building is built on. The “Threshold Tray and Clip System” uses mass-produced products to be applied to construction of slabs and foundations, allowing sill steps to be built in rough openings with pre-fabricated form parts. The forms remain in the concrete and are permanent. This means that consistent results can be expected. Other mass-produced products, such as door systems, will fit into rough openings more accurately. Over-all quality of the structure will be increased.Type: GrantFiled: September 15, 2003Date of Patent: August 1, 2006Inventor: James Edward Visser

Patent number: 6523310Abstract: The present invention relates to a tread and handrail combination structure of a staircase, including a support post, multiple helically laminated treads mounted on the support post, and multiple juxtaposed handrails. Each tread has an outer side provided with multiple combination holes, so that two ends of each handrail may pass through the combination holes to be fixed on the tread. Each tread has a bottom face provided with a support tube aligned with one combination hole. One end of each handrail is screwed on the tread, and the other end of each handrail is extended through the combination hole and the support tube of the mating tread, and through the combination hole of a next tread, so that any two adjacent treads may be combined rigidly and stably, without deformation.Type: GrantFiled: November 23, 2001Date of Patent: February 25, 2003Assignee: Taiwan Lounge Chair Industry Co., Ltd.Inventor: Chen-Nung Tseng

Patent number: 6516574Abstract: The present staircase includes a permanent framing made of metallic stringers, one of which being typically secured to a half-timbering. vertically extending step supports are secured along the stringers and each include upper and front flanges adapted to be secured respectively to a tread and to a riser of each step of the staircase. A temporary staircase may be easily obtained with the present kit for use during construction, wherein a number of L-shaped steel step units are laid onto the step supports to form a successive series of alternating risers and treads. Then, these L-shaped steel units can be removed and replaced by finished steps of various configurations. If the staircase has an exposed side, a finishing stringer is provided thereat to conceal the structural metallic stringer.Type: GrantFiled: June 30, 1999Date of Patent: February 11, 2003Assignee: Stairframe Systems Inc.Inventor: Raymond Couture
