Abstract

A method and a system for a cable infill system that may be used with a railing assembly for an elevated structure are provided. The cable infill system may include a first end-post fitting and a second end-post fitting, each configured to receive a tensioning fitting or a non-tensioning fitting therein for receiving a cable of the railing assembly. The first end-post fitting and the second end-post fitting may each be mounted to an outer surface of a first end-post and a second end-post of the railing assembly respectively. The cable infill system may further include one or more intermediate-post fittings and one or more corner-post fittings, each configured to be mounted on an outer surface of a intermediate-post or a corner-post of the railing assembly respectively. The cable infill system may further include a modular template to aid the installation of various fittings on the posts.

Claims (40)

1 . A cable infill system comprising:

a first end-post fitting configured to receive a first tensioning fitting or a first non-tensioning fitting for receiving a cable, wherein the first end-post fitting is configured to be mounted on an outer surface of a first end-post of a railing assembly; and

a corner-post fitting configured to guide the cable around a corner post of the railing assembly,

wherein the corner-post fitting comprising a first leg and a second leg, wherein the first leg is configured to be mounted on a first outer surface of the corner post and the second leg is configured to be mounted on a second outer surface of the corner post,

wherein the first leg of the corner-post fitting includes a first fastening hole for receiving a first fastener and the second leg of the corner-post fitting includes a second fastening hole for receiving a second fastener.

2 . The cable infill system of claim 1 further comprising:

a second end-post fitting configured to receive a second tensioning fitting or a first non-tensioning fitting for receiving the cable, wherein the second end-post fitting is configured to be mounted on an outer surface of a second end-post of the railing assembly, thereby securing the cable on the railing assembly between the first end-post and the second end-post.

3 . The cable infill system of claim 2 , wherein the first end-post fitting and the second end-post fitting each comprising an aperture for receiving a tensioning fitting or a non-tensioning fitting; and

a fastening hole for receiving a fastener,

wherein the aperture and the fastening hole extend through the respective end-post fitting in different directions.

4 . The cable infill system of claim 1 further comprising an intermediate-post fitting configured to receive the cable through a cavity of the intermediate-post fitting, wherein the first end-post fitting is configured to be mounted on an outer surface of an intermediate-post of the railing assembly.

5 . The cable infill system of claim 4 , wherein the cavity of the intermediate-post fitting comprising a central bore provided in between two terminal portions,

wherein each of the terminal portions extends from a surface of the intermediate-post fitting toward the central bore, and each of the terminal portions having a decreasing diameter from the surface toward the central bore.

6 . The cable infill system of claim 5 , wherein the central bore comprises a diameter that is generally uniform throughout a length of the central bore.

7 . The cable infill system of claim 4 , wherein the intermediate-post fitting further comprising a fastening hole for receiving a fastener, wherein the cavity and the fastening hole extend through the intermediate-post fitting in different directions.

8 . A cable infill system comprising:

a first end-post fitting configured to receive a first tensioning fitting or a first non-tensioning fitting for receiving a cable, wherein the first end-post fitting is configured to be mounted on an outer surface of a first end-post of a railing assembly; and

a corner-post fitting configured to guide the cable around a corner post of the railing assembly,

wherein the corner-post fitting comprising a first leg and a second leg, wherein the first leg is configured to be mounted on a first outer surface of the corner post and the second leg is configured to be mounted on a second outer surface of the corner post;

wherein the first leg of the corner-post fitting includes a first cable opening and the second leg of the corner-post fitting include a second cable opening, wherein a channel is provided between the first cable opening and the second cable opening for receiving the cable within the corner-post fitting.

9 . The cable infill system of claim 1 further comprising a template configured to position a plurality of end-post fittings, a plurality of intermediate-post fittings, or a plurality of corner-post fittings on a post of the railing assembly for mounting.

10 . A cable infill system comprising:

a first end-post fitting configured to receive a first tensioning fitting or a first non-tensioning fitting for receiving a cable, wherein the first end-post fitting is configured to be mounted on an outer surface of a first end-post of a railing assembly; and

a template configured to position a plurality of end-post fittings, a plurality of intermediate-post fittings, or a plurality of corner-post fittings on a post of the railing assembly for mounting,

wherein the template is modular and comprising one or more intermediate modules, wherein a length of the template can be adjusted by adding or removing the one or more intermediate modules.

11 . A method for a cable infill system comprising:

providing a first end-post fitting configured to receive a first tensioning fitting or a first non-tensioning fitting for receiving a cable, wherein the first end-post fitting is configured to be mounted on an outer surface of a first end-post of a railing assembly; and

providing a corner-post fitting configured to guide the cable around a corner post of the railing assembly, wherein the corner-post fitting comprising a first leg and a second leg, wherein the first leg is configured to be mounted on a first outer surface of the corner post and the second leg is configured to be mounted on a second outer surface of the corner post.

12 . The method of claim 11 further comprising:

providing a second end-post fitting configured to receive a second tensioning fitting or a first non-tensioning fitting for receiving the cable, wherein the second end-post fitting mount is configured to be mounted on an outer surface of a second end-post of the railing assembly, thereby securing the cable on the railing assembly between the first end-post and the second end-post.

13 . The method of claim 11 further comprising:

providing an intermediate-post fitting to be mounted on an outer surface of an intermediate-post of the railing assembly, wherein the intermediate-post fitting includes a cavity to receive the cable therethrough.

14 . The method of claim 13 , wherein the cavity of the intermediate-post fitting comprising a central bore provided in between two terminal portions,

wherein each of the terminal portions extends from a surface of the intermediate-post fitting toward the central bore, and each of the terminal portions having a decreasing diameter from the surface toward the central bore.

15 . The method of claim 11 further comprising:

providing a template configured to position a plurality of end-post fittings, a plurality of intermediate-post fittings, or a plurality of corner-post fittings on a post of the railing assembly for mounting.

16 . A method for a cable infill system comprising:

providing a first end-post fitting configured to receive a first tensioning fitting or a first non-tensioning fitting for receiving a cable, wherein the first end-post fitting is configured to be mounted on an outer surface of a first end-post of a railing assembly; and

providing a template configured to position a plurality of end-post fittings, a plurality of intermediate-post fittings, or a plurality of corner-post fittings on a post of the railing assembly for mounting;

wherein the template is modular and comprising one or more intermediate modules, wherein a length of the template can be adjusted by adding or removing the one or more intermediate modules.
