Aspects of the disclosure relate to a railing system. The railing system can include a tensioning device. This tensioning device can include one continuous strand of cable, wire rope, or similar (hereafter referred to as “cable” or “wire”), to be threaded through, back and forth, two loom members, to create a railing “panel”. The loom members can be designed or configured to organize the cable so that the distance between each strand does not exceed spacing requirements in the building codes for railing balusters.
Two loom members can be used to thread the cable(s) through, one loom member can be placed on each “end” of the panel. The loom member can further incorporate the ability to secure one of the loose ends of the cable within or at each loom member. To secure the panel, the loom member may include threaded bolts, screws, or similar, to anchor the cable panel between structures, for example, railing posts. Once the loose cable ends are secured, the anchors may act as the tensioning device, which may be tightened to tension the cables. The cable is routed between the loom member in such a way that, as the anchors apply tension, the cable is able to pass through the loom members so that even tension is applied to each cable portion or “loop”. This equal tension can provide, at least, the advantage of being able to tension an entire panel of cable at once, with even tension automatically applied to each cable loop, rather than having to tighten each individual strand.
When appropriate anchors and railing posts are used, the tensioning device can apply greater tension, approaching the working load limits of the cable, (without cable slippage or release). The tension applied may be greater than many common cable railing devices currently available. This added tension, in turn, can allow for higher levels of use/abuse, i.e., climbing of cables or absorbing impacts (e.g., from people falling into the cables), without failure. Also, in the event of that the cable(s) do stretch and the panel is not tensioned fully or adequately, the existing cable can easily be re-tensioned by retightening the anchors.
A pair of the railing looms may be provided to create individual railing panels, one pair of tensioning devices may be provided for each railing loom. In at least some implementations, the railing posts may be constructed or altered to allow the cable to be threaded through one or more posts, in a straight line or around corners. In this case, one pair of tensioning devices can be provided to organize and stretch cable through multiple railing posts or panels.
The cable ends can be secured or held by the loom members. To hold the cables, a device, e.g., a swaged button stop ferrule or similar, may be applied to each cable end. Then, the device is inserted and held in a hole or pocket of the loom member. As tension is applied to the device, via anchors, the cable end device is drawn into the pocket but not allowed to pass through the pocket (e.g., the pocket or hole diameter is sized for button stop but the end of the pocket is smaller than the button stop). The pocket can conceal the button stop, and the cable attached to the button stop can pass through on the other side of the loom member (e.g., on the cable-panel-side of the loom member). The slack in the cable required to install the button stop may be evenly distributed through the rest of the cable loops during tensioning. As the tensioning devices apply tension, the cable is drawn through the loom members, applying even tension to each strand of cable.
The loom member user one each side of the panel may be identical. However, one of the loop members may be rotated 180 degree, that is, may be used upside down. Thus, the pocket for securing the loose cable end may be at the top on one side of the cable panel, and at the bottom on the other side of the panel. With this configuration, there is only loom member to manufacture for both sides of the panel; the loom member is universal in application. Also, a loom member is when on opposing sides of a rail post, or at a corner post, the tensioning devices do not align because one of the loom members is inverted and the tensioning devices are offset. Thus, the tensioning devices can be separated far enough apart from each other that the tensioning devices do not intersect, collide, or interfere with the operation of each other inside the post.
In instances where an even number of cable loops are required to meet a desired cable spacing and panel height, modifications to the loom members may be made. For example, both cable ends may be secured on the same loom member. The other loom member may include cable paths but no pocket to secure the cable ends. This change to the design can locate the tensioning devices back to back, on opposing sides of a single rail post, with no interference of the tensioning devices.
This railing system creates a unique appearance among cable railings, in that each cable does not touch, pierce, or bisect every post. In fact, this can be installed so that no cable touches any post, thereby breaking up the horizontal lines of the cables with the vertical posts, and creating individual cable railing panels that are independent of the posts.
This railing system can also have at least some significant improvements over previous cable railing designs of other railing systems (e.g., wooden, welded steel, iron, etc.). First, the cables can loop freely through the back of the loom member (allowing the cables to slide freely), rather than weaving back forth. Weaving the cables rather than looping those cables can cause the cables to bind and kink, which makes the installation of the cables more difficult. Also, the anchor bolts can be welded to the tensioner and require access to the nut that tensions the device. This design can cause the anchor to protrude through railing posts or require a large enough hole be provided on the far side of the rail post to allow tools to access the tensioning nut. The aspects described herein allow for the tensioning bolt to be turned so that the nut can be fixed in or on the adjacent railing post or anchoring structure.
An implementation of the railing system 100 maybe as shown in
Referring to
The gap 105 between the loom members 202a and 202b maybe spanned by one or more cables or wires 204a, 204b, 204c, 204d, 204e, 204f, 204g, 204h, and/or 204i, etc. The cables or cables 204 may be braided metal strand cables or other types of cables. The length of the cable(s) 204 and the gap between the cable(s) 204 may be determined by the height of the railing system and based on any laws or rules acquiring a certain distance or maximum distance between the cables 204. In one configuration, each cable 204a-204i may represent a single cable that is terminated at each end at the first loom member 202a or the second loom member 202b. In another configurations, cables 204a-204i are a single cable terminated at a top of a member 202a and at the bottom of loom member 202b. This single cable 204 can be threaded or woven between the loom members 202, back and forth, to provide the various cable spans 204a-204b in the panel 106.
Example implementations of a post 102 and/or top rail 104 maybe as shown in
Post 102 may also be rigid and resist deflection. For example, the post 102 may be wood or metal. The post 102 can also include one or more tapped holes 306a, 306b on opposing sides 312 the post 102. These holes 306 accept the coupling/tensioning devices 206 inserted through the loom members 202. In at least some configurations, the tapped holes 306 accept the bolt 206 that can be screwed into the tapped hole 306. If the post 102 is wood, the tapped hole may be an insert, with a tapped hole, glued of affixed into a recess or aperture set or created in the post 102. In other configurations, the threaded holes 306 may be absent from a wooden post. In such configurations, the tensioning device 206 maybe a screw or through bolt that is screwed into or threaded to a nut on the other side of the wooden post 102 to tension the cables 204.
A configuration of the rail 104, as set into the railing acceptor 302 may be as shown in
A cross sectional view of the post 102 and railing 104 assembly may be as shown in
Loom member 202 may be as shown in
One or more portions or sections may form the loom member 202. A first portion or section can be a full loom section 605 which includes only material without any machining, for example, no threading, no opening, etc., in this solid section of material. A next section maybe a cable u-shaped section 604a through 604d. The u-shaped section(s) 604 can accept a cable through an inlet opening 608. The cable 204 may be routed around and held against the u-shaped portion 610, with the cable 204 routed out of the outlet opening 614. U-shaped section 604 is formed from a material portion or u-shaped channel 612 that allows the cable to be looped around the solid material within the loom member 202. The u-shaped section 610 forms an opening or cut out that keeps the cable confined within the loom member 202 but allows access to the u-shaped section 604 and the cable through the back portion of the loom member 202.
Another portion 602a, 602b can include an opening or aperture that holds a tensioning device 206 attached to the loom member 202 and the post 102. The tensioning device 206 may be a bolt or similar to couple the loom member 202 to the post 102. The tensioning device 206 can be thread through an opening 618, in the loom member 202, and exit opening 620. Part of the tensioning device, e.g., a head of the bolt, may be retained in opening 622 and may be accessible through opening 616. The tensioning device 206 can be placed through the loom member 202 and coupled to the post 102. Aperture 616 can accept tools to tighten the tensioning device 206.
Another section of the loom number 202 can include a portion 606 to retain the cable end. The cable end retention section 606 includes larger aperture 626, which holds a retention device, e.g., a swaged button stop ferrule or similar, which ca be placed at and affixed to the end of the cable 204. The retention device may be affixed to the cable end by mechanical means, adhesive, etc. The opening 628 can allow the cable 204 to pass through an opening 624 to exit out the outlet 628. In this way, the cable 204 is retained by the loom member 202 and a tension can be applied by the loom member.
The cables 204 may be attached to the first loom member 202a at the first retention opening 606, which may be at the bottom of the panel 106. The second loom member 202b may be inverted with the opening 606 at the top and at the other side of the panel 106. The other end of the cable may then be captured within opening 620 at the top of the second loom member 202b.
The cables may be strung might be strong through the various different openings 608a-608d and 614a-614d. The openings 608, 614 and u-shaped sections 604 allow the cable to be threaded through the two loom members 202a, 202b, back and forth, to create the panel 106. The tensioning bolts may be accessed through the hole opening 606, from a front side, of the loom member 202. As shown in
A second implementation of the loom member 202 may be modified for stair applications, as shown in
Openings 608, 614 can have countersunk portions 1202a, 1202b, which may be a bevel at the edge of the opening 608, 614. The bevel 1202 reduces any strain on the cable 204 when the cable is strung diagonally (rather than at a right angle to the loom member 202) from the two loom members 202.
Elongated openings 1204 and 1208 are formed in the back of the stairway loom member 202 that change the access to the portion 602. The elongated openings 1204 and 1208 can allow the tensioning device 206 to pass through the stairway loom member 202 at an angle from stairway loom member 202 to the post 102. With this configuration, the stairway loom member 202 and the attached cables 204 can be tensioned at an angle or in a direction parallel to the cables on stairs. Further, the stairway loom member 202 may also have a bevel or angle at the ends 1212a, 1212b. This bevel angle may be decorative, however the bevel 1212 can provide a visual indicator of whether the bolts are mounted correctly when initially attaching the stairway loom member 202 or coupling the stairway loom member 202 to the post 102.
Stairway loom members 202 can have an aperture or opening 1206 provided through the side of the stairway loom member 202. This opening 1206a-1206d allows for a pivot bolt (see
Another view of the opening 1206 is shown in the cross section view of

An anchor nut 1712 may then be inserted through one or more openings 1714a and 1714b through the sides 1716 of the retention box 1704. In implementations, the anchor nut 1712 is a barrel nut with a tapped hole 1718 in the side of the barrel nut 1712. A slot 1720 in the end 1722 of the barrel nut 1712 accepts a screwdriver tip that allows for the adjustment of the orientation of the barrel nut 1712 in relation to the retention box 1704. The tapped hole 1718 can accept the bolts 206 or another tensioning device from loom member 202.
The outer covering 1724 may be placed within the opening 1726 of the retention box 1704. The covering 1724 can include a hole 1728 that allows the bolt 206 to pass through the covering 1724 and be inserted into the hole 1718. The configuration shown in
