    • A traction element for carpeted stair treads or other flooring includes a deformable substrate secured by screws to the tread that is vertically aligned with the top edge of a riser and slightly rearward of the tread leading edge. The substrate is covered with adhesive backed friction tape. The screws extend through respective apertures centered in respective concave tapered annular recesses defined in the substrate. The apertures are in a linear array defining a bend axis along the substrate length and the tread width and about which the substrate deforms as it is being threadedly attached to the tread. When thusly bent the substrate top surface becomes concave such that its forward edge is higher than its rearward edge, thereby establishing a slight forwardly extending incline. The tape strip conforms to the bent substrate and its exposed top surface comprises a high friction or abrasive substance.
    • 用于地毯阶梯踏板或其它地板的牵引元件包括通过螺钉固定到胎面上的可变形基底,其与竖立件的顶部边缘垂直对准并且在胎面前缘稍微向后。 衬底被粘合剂背衬的摩擦带覆盖。 螺钉延伸穿过限定在基板中的相应的凹形锥形环形凹部中心的相应孔。 所述孔是线性阵列,其限定沿衬底长度和胎面宽度的弯曲轴线,并且衬底随着螺纹连接到胎面而变形。 当如此弯曲时,衬底顶表面变成凹形,使得其前边缘高于其后边缘,从而建立轻微的向前延伸的倾斜。 带条符合弯曲的基材,其暴露的顶表面包括高摩擦或磨料物质。

    • An exemplary stair nosing assembly comprises an elongated base, a plate adhered to the base, and a cover temporarily covering the base and the plate. The base has at least one anchor portion extending downwardly from the upper portion for attaching to a lip of a tread pan and/or embedding in a concrete tread. The plate can have various features to enhance traction and visibility. The cover has front and rear lips that engage with front and rear edges of the base, and a weakened region adjacent the rear lip. When the assembly is embedded in a concrete tread, the cover is configured to fracture at the weakened region when the front lip of the cover is lifted upward from the base, leaving the rear lip remaining embedded in the concrete and allowing the rest of the cover to be removed to expose upper surfaces of the base and plate.
    • 示例性的楼梯组件包括细长基座,粘附到基座的板和临时覆盖基座和板的盖。 底座具有从上部向下延伸的至少一个锚定部分,用于附接到踩踏盘的唇缘和/或嵌入在混凝土胎面中。 该板可以具有各种特征以增强牵引力和可视性。 盖具有与基部的前后边缘接合的前后唇部和与后唇相邻的弱化区域。 当组件嵌入在混凝土胎面中时,盖被构造成当盖的前唇从基座向上提升时在弱化区域处断裂,留下后唇留在混凝土中并允许盖的其余部分 被去除以暴露底板和板的上表面。

    • Provided is a system and method for removable stair treads and risers having a bracket with a horizontal mounting surface and a vertical mounting surface. The bracket has openings on the horizontal mounting surface to allow a fastener to secure the bottom of a stair tread to the bracket. The bracket has openings on the vertical mounting surface to allow a fastener to secure the bracket to a supporting structure. The vertical mounting surface has at least one recess connected to a primary portion of an attaching element. A riser has a secondary portion of an attaching element attached to an unexposed surface of the riser located opposite at least one recess of the bracket. This allows the riser to be removably attached to the bracket without causing damage to the surrounding stair treads or risers.
    • 本发明提供一种用于可拆卸楼梯踏板和立管的系统和方法,该系统和方法具有一具有水平安装表面和垂直安装表面的托架。 支架在水平安装表面上具有开口,以允许紧固件将楼梯踏板的底部固定到支架上。 支架在垂直安装表面上具有开口,以允许紧固件将支架固定到支撑结构。 垂直安装表面具有连接到附接元件的主要部分的至少一个凹部。 提升器具有附接元件的辅助部分,附接元件附接到与支架的至少一个凹部相对的提升管的未曝光表面。 这允许提升管可移除地附接到支架而不会损坏周围的楼梯踏板或立管。
