Abstract
A baluster retaining member for connecting an end of a baluster to an opening in a rail of a railing system includes a rail section dimensioned to fit within the opening and a baluster section dimensioned to be secured to an end of the baluster. The rail and baluster sections are oriented with respect to one another at a predetermined angle so that when the baluster is connected to the rail by the member and the rail is positioned for use adjacent a stairway at an angle from the horizontal, the baluster is oriented vertically.
Description
BALUSTER RETAINING MEIUIBER
Background of the Invention i) Field of the Invention:
This invention relates to a retaining member for connecting balusters to rails of a railing system and more particularly relates to a system which permits vertical orientation of balusters into rails having openings perpendicular to the longitudinal axis of the rails, where the rails are oriented at an angle from the horizontal when adjacent a stairway.
ii) Related Art Railing systems which are made up of upper and lower rails with balusters interposed between the rails are well known in the art. As well, a railing system in which the balusters are inserted into openings in a surface of each rail are well known.
In those systems, the upper and lower rails are rigidly connected to posts on each end with the balusters interposed between the rails fitted within openings in the Lower surface of the upper rail and the upper surface of the lower rail to hold the balusters in place. The balusters are manually oriented in a vertical direction, irrespective of the angle at which the rails are oriented. Because rails positioned adjacent a stairway or set of stairs must be angled downwardly at an angle corresponding to the angle of the stairway (that is the angle corresponding to the "run" and "rise" of the stairway), difficulties can arise in providing a method for orienting the balusters vertically when interposed between rails which are angled from the horizontal.
In the past, one method of manufacturing rails for this type of railing system was to orient the openings in each rail into which an end of a baluster is inserted at an angle in relation to the longitudinal axis of the rail sufficient to result in a vertical baluster orientation when the rails are angled in use adjacent a stairway. This has meant that special tooling equipment, or time consuming adjustment of existing equipment had to be undertaken to drill these openings at the appropriate angle. Furthermore, some railing systems are sold, without any pre-drilled openings, to consumers and contractors who install these systems. Consumers or contractors are then required to drill openings of appropriate size and orientation in order t~ accept the balusters between the rails when the railing system is assembled. It is much easier for those consumers or contractors to drill openings in the rails which are perpendicular to the longitudinal axis of those rails, as compared to attempting to drill a plurality of openings at the same angle, corresponding to the rise angle of the stairway, to provide a consistent vertical orientation of a plurality of balusters between the rails whE;n those rails are positioned adjacent a stairway at an angle from the horizontal. This difficulty is compounded by the need to ensure that openings in the top rail align with openings in the bottom rail.
As well, the ability to use rails which have an opening perpendicular to the longitudinal axis of the rail permits consumers and contractors to use the same rails for use in a railing system adjacent a set of stairs as are used in a railing system adjacent a horizontal surface. In addition, the rails may be oriented with a particular end either at the high end of the stairway, or the low end of the stairway, whereas rails having angled openings are required to be oriented in one direction to properly align the openings so that the balusters are oriented vertically.
As a consequence, there is a need for a railing system which permits the use of rails having openings to accept balusters between the rails which are formed into the rails in a direction perpendicular to the longitudinal axis of the rails and which enables vertical orientation of the balusters interposed between the rails when the rails are oriented at an angle from the horizontal such as when the rails are used adjacent a stairway.
The railing system of one embodiment of the subject invention requires that the balusters used with rails positioned adjacent a stairway or set oi~ stairs be cut at each end to properly fit retaining members, as best depicted in figure 2A. This requires further processing of balusters by the baluster manufacturer or kyy the user in order to properly fit balusters with inserts and rails when used adjacent the stairway or set of stairs. in most cases the manufacturer will not know how many balusters are required 'to be cut for use in a railing system adjacent a stairway as compared to the number needed in a railing system along a flat section, that is, not positioned adjacent a stairway. Similarly, users may not know the exact number of balusters which will be positioned adjacent a stairway at the time they purchase a railing system.
As a consequence, there is a need for a railing system in which balusters having ends perpendicular to the longitudinal axis of the baluster may be employed both in straight railing sections and angled sections positioned adjacent a stair way. This eliminates the need to cut baluster ends at an angle either when initially manufactured or by the installer for use adjacent a stairway. Further when only one type of baluster is required for use in the entire railing system neither the manufacturer nor the installer need be concerned about the number of balusters needed adjacent staiirways and the number along a flat section in order to obtain the appropriate number of balusters for each type of application.
In addition, the railing system of the embodiment depicted in fige.are 1A
results in direct contact between the wood rails and the aluminium balusters when the balusters are inserted into the holes in the rails. in most cases, the wood used for outdoor railing systems has been pressure treated with a preservative, a sually either chromated copper arsenate (CCA) or alkaline copper quaternary (AC(~). Both preservatives contained copper which can react adversely with aluminum to corrode the aluminum.
As aluminum is a preferred metal for manufacturing balusters in the present invention, there is a need for an alternate embodiment railing system utilizing inserts between the baluster and the rails which also separates the baluster from the rails to prevent copper induced corrosion of the aluminum balusters.
Summary of the Invention in one embodiment the invention provides a railing system for a stairway which includes a pair of rails, each having a plurality of openings extending lateraily into one side of the rails in a direction perpendicular to the longitudinal axis of the rails. A
plurality of balusters are provided for extending between the rails and a plurality of retaining members are provided for con~~ecting an end of a baluster to one of the openings. The retaining members include a rail section dimensioned to fit within the opening and a 5 baluster section dimensioned to be secured to an end of the baluster. The rail and baluster sections are oriented with respect to one another at a predetermined angle so that when the balusters are connected to the rails by the members and the rails are positioned for use adjacent a stairway at an angle from the horizontal, the balusters are oriented vertically.
In a further embodiment, the rail section is of an outer diameter and the opening is of a corresponding diameter to provide a friction fit of the rail section within the opening.
In a further embodiment, the baluster includes a baluster opening at one end dimensioned to accept the baluster and of the retaining member into the baluster opening.
In a further embodiment, the baluster section is of an outer diameter and the baluster opening is of a corresponding diameter to provide a friction fit of 'the baluster section within the opening.

Detailed Description of the Preferred Embodiments) Referring initially to Figures 1 and 1A, railing system 10 is shown adjacent stairway or set of stairs 12. Railing system 10 includes balusters 14 interposed between upper rail 16 and lower rail 18.
Stairway 12 includes a pair of parallel-spaced opposed stringers 20 and 22 attached at an upper end to beam 24. Lower ends of stringers 20 and 22 rest on a support surface (not shown). A plurality of tread members 26 are positioned horizontally on corresponding plurality of vertical support sections 27 of stringers 20 and 22.
A typical stairway 12 has a 7 inch rise 30 and a 11'/4 inch run 32 which is equivalent to a rise angle 28 from a horizontal support surface of about 3.2.5 degrees.
Railing system 10 includes upper post 34 and lower post 36. Upper post 34 is secured to a top face 38 of beam 24 and lower post 36 is attached to, or rests on, the support surface and is attached to a lower region of stringer 22. Lower post 36 may further be attached to the lowermost tread member 26 at notch 40. Upper and lower rails 16 and 18 are positioned between the posts 34 and 36 and extend downwardly from upper post 34 to lower post 36 at an angle of about 32.5 degrees from the horizontal so as to correspond with rise angle 28 of stairway 12. Upper and lower rails 16 and 18 have parallel ends which are cut at an angle of about 32.5 degrees from that perpendicular to the longitudinal axis of rails 16 and 18 which also corresponds to the rise angle 28.
VUhen railing system 10 is assembled adjacent stairway 12, rails 16 and 18 are attached to a side of posts 34 and 36 so that the ends of rails 16 and 18 lie flush with adjacent sides of posts 34 and 36. This ensures that the angle of rails 16 and 18 from the horizontal, that is angles 80 and 82 shown in Figure 2A, correspond to rise angle 28 ensuring that rails 16 and 18 are positioned generally at are angle from the horizontal corresponding to rise angle 28 of stairway 12.
A plurality of balusters 14 are interposed between rails 16 and 18 and are rigidly secured between those rails in a vertical orientation, while rails ~ 6 and 18 are oriented at an angle from the horizontal as discussed above. Referring to Figures 1A
and 2A, in order to provide for a vertical orientation of balusters 14 in conjunction with rails 16 and 18 which are angled from the horizontal by angles 82 and 80, retaining members 42 are employed to attach balusters 14 to rails 16 and 18. Upper face 44 of rail 18 includes a plurality of openings 46 extending laterally into face 44, representing a side of rail 18, in a direction perpendicular to face 44 also perpendicular to the longitudinal axis of rail 18.
Retaining member 42 fits within opening 46 and includes rail section 64 which is dimensioned in width with respect to the width of opening 46 to provide a friction fit engagement within opening 46. Baluster 14 includes opening 48 in an end of baluster 14 into which baluster section 62 of retaining member 42 may be inserted.
Baluster section 62 of retaining member 42 is dimensioned in width with respect to opening 48 to provide a friction fit engageme~lt with opening 48 into which baluster section retaining member 42 is inserted. This is best seen in Figure 2A.
As best depicted in Figures 2 and 2A, upper rail 16 includes a lower face 50 into which a plurality of openings 52 are formed. Openings 52 extend laterally into face 50 and thereby into one side of rail 16. Openings 52 are of the same diameter and length as openings 46. Openings 52 extend in a direction perpendicular to face 50 and perpendicular to the longitudinal axis of rail 16. Rail section 64 of retaining member 42 and opening 52 are dimensioned to provide a friction fit engagement of rail section 64 within opening 52. Baluster 14 includes an opening (not shown) at its upper end 54, similar to opening 48 in lower end 56 of baluster 14 as described above.
Baluster section 62 of retaining member 42 and the opening in end 54 are dimensioned fio provide a secure friction fit engagement of baluster section 62 of member 42 within the opening at end 54.
Ends 54 and 56 are cut at an angle from the longitudinal axis equal to rise angle 28 of about 32.5 degrees and are parallel with one another. This ensures that upper face 58 and lower face 60 are coplanar with faces 50 and 44, respectively. Lower face 60 is shown in its assembled position coplanar with face 44 in Figure 1A.
Referring to Figures 3, 4, 5, and 6, retaining member 42 is depicted in perspective, side, front and rear views. Retaining member 42 includes baluster section 62 integrally joined to rail section 64. Baluster section 62 includes four ribs 56 oriented at right angles to one another and extending the length of baluster section 62. Ribs 66 are integrally joined with four ribs 68 oriented at right angles with respect to one another of rail section 64. Ribs 68 of rail section 64 are wider than ribs 66 providing a larger diameter 70 as compared to diameter 72 of baluster section 62 (best seen in Figure 4).
UVhile not shown, ribs 66 may be tapered with a larger diameter adjacent ribs 68 to provide a general frusto-conical outer periphery to facilitate insertion of baluster section 62 into baluster 14.
As best seen in Figure 4, rail section and baluster section .are angled with respect to one another at angle 74 which is equivalent to rise angle 28 of ataout 32.5 degrees.
~lllhen rails 16 and 18 are oriented at an angle from the horizontal at angles 82 and 80, respectively, of about 32.5 degrees, rail section 64 may be inserted into opening 46 or opening 52 with baluster section 62 oriented in a vertical direction (see Figure 1A). As depicted in Figure 2A, retaining member 42 is inserted into opening 52 so that baluster section 62 faces vertically as is baluster section 62 of retaining member 42 positioned within opening 46 of rail 18. This properly orients baluster 14 in a vertical position as depicted in Figures 1 and 2 when attached to both baluster sections 62 of retaining members 42.
Rail section 64 is dimensioned at diameter 70 which is generally equivalent to diameter of openings 46 and 52 to provide a friction fit of rail section 64 within either one of openings 46 or 52. As well, the length 76 of rail section 64 is equal to the depth of openings 46 and 52. As best seen in Figures 3 and 4, because ribs 68 are of larger diameter 70 as compared to diameter 72 of ribs 66, lip 78 is formed at the inner end of ribs 68 where ribs 68 merge with ribs 66. Lips 78 on ribs 68 are in coplanar alignment with each other as ribs 68 are all of equal length 76.
Length 76 is equal to the depth of openings 46 and 52 and when rail section 64 is 5 positioned within opening 46 or opening 52 with rail section 64 contacting the end of opening 46 or opening 52, lips 78 are in coplanar alignment with the plane of corresponding face 44 or 50. As a consequence, when baluster section 62 is positioned within one of opening 48 or opening in end 54 of baluster 14, lips 48 act as a stop contacting corresponding face 58 or 60 which rests against lip 78, as best depicted in 10 Figure 1A. This provides additional support to balusters 14 which contacts lips 78, rather than faces 44 or 50 which are generally made of wood or other soft material, softer than material used to construct retaining members 42.
As well, because retaining members 24 have rail section 64 which is positioned at angle 15 74 with respect to baluster section 62, equivalent to angles 80 and 82 of rails 18 and 16, balusters 14 are oriented in a vertical position.
The foregoing description of a preferred embodiment has been directed to the most popular rise and run angle of a stairway, namely a 7 inch rise and an 11 %4 inch run, resulting in about a 32.5 degree angle from the horizontal. However, other stair angles may also be accommodated and will similarly provide a 'vertical baluster interposed between rails angled from the horizontal by changing the predetermined angle of the retaining member 42. For example, other popular stair runlrise ratios are: (i) a rise of 6 112 inches and run of 11 inches, resulting in a rise angle of about 30 degrees; (ii) a rise of 7'h inches and run of 10 inches resulting in a rise angle of about 36 degrees; and a rise of 7'/e inches and a run of 10'/4 inches resulting in a rise angle of about 35 degrees. By providing a predetermined angle 74 and positioning rails 16 and 18 at angles 82 and 80 equivalent to 30 degrees a rise of 6 112 inches and a run of 11 inches can be accommodated. Similarly, a rise of 7'/2 inches and a run of 10 inches can be accommodated by providing angles 74, 82 and 80 of 36 degrees and a rise of 7 %4 and run of 10'/4 accommodated by providing angles 74, 82 and 80 of 35 degrees.
An alternate embodiment of the invention will now be discussed with reference to Figures 7-12. This embodiment provides an alternate retaining member 142 which incorporates buffer section 190 which is angled thereby obviating the need to cut upper end 54 and lower end 56 of baluster 14 at an angle different frorn that perpendicular to the longitudinal axis of baluster 14.
Retaining member 142 also separates baluster 14 from rails 16 and 18 to prevent copper induced corrosion of baluster 14 caused by the copper in the preservative commonly found in rails 16 and 18. As depicted in figure 1A, use of retaining member 42 of the first embodiment discussed above causes contact between lower face 60 of baluster 14 and upper face 44 of lower rail 18~ Although not shown, similar contact will occur between upper face 58 of baluster 14 and lower face 50 of upper rail 16.
Referring to Figures 7 and 8, retaining member 142 is a perspective view with Figures 7 viewed facing baluster section 162 and Figure 8 viewed facing rail section 164. Buffer section 190 is positioned between sections 162 and 164 arid joins sections 162 and 164 together.
Buffer section 190 has a cylindrical outer periphery with a wedge shaped cross-section.
Baluster section end face 192, sometimes referred to as a first face, forms a first end attached to baluster section 162, seen best in Figures 7 and 10. Rail section end face 194, sometimes referred to as a second face, forms a second end attached to rail section 164, seen best in Figure 8.
Referring to Figure 9, a plane defined by face 192 is oriented with respect to a plane defined by face 194 at angle 196, equal to a predetermined angle which will orient baluster 14 vertically when attached to lower rail 18 when rail 18 is positioned adjacent a stairway or set of stairs 12. The predetermined angle may be iaetween 30 degrees and 36 degrees and preferably is about 32.5 degrees when use adjacent a stairway 12 having a 7 inch rise 30 and 11 1/4 inch run 32 (Figure 1 ).
Retaining member 142 includes rail section 164 which is dimensioned in width with respect to the width of opening 52 to provide a friction fit engagement with opening 52.
Retaining member 142 also includes baluster section 162 which is dimensioned in width to provide a friction fit engagement with opening 48 of baluster 14.
Face 192 is planar and is dimensioned to contact baluster 14 when baluster section 162 is inserted in opening 48 as depicted in Figure 9. Face 192 prevents baluster 14 from moving past baluster section 162 in the direction of rail section 154.
Referring to Figure 8, face 194 has a diameter larger than the diameter of opening 52 to contact upper face 44 of lower rail 18 when rail section 164 is inserted into opening 52 to prevent retaining member 142 from entering opening 52 past rail section 164.
It should further be noted that, as depicted in Figure 9, the bottom end of baluster 14 is cut perpendicular to the longitudinal axis of baluster 14 due to the interposing of buffer section 190 between baluster section 162 and rail section 164 and the positioning of faces 192 and 194 with respect to each other at angle 196. As well, buffer section 190 separates the bottom end of baluster 14 from upper face 4.4 of lower rail 18 preventing contact between baluster 14 and rail 18 to reduce the effect of any copper induced corrosion on baluster 14.
Referring to Figures 11 and 12, ~~retaining member 142 is shown in a cross-section view.
In order to improve the securing of baluster section 162 into opening 48 a plurality of barbs 198 are provided at the outer edge of each cross member 200 (Figure 7).
Barb 198 is shown in close up in Figure 12 and comprises elongated sloped section connected to lateral section 204. Lateral section 204 is positioned closer to buffer section 190 as compared to sloped section 202. As best seen in Figure 9, this provides additional means of securing baluster 14 in opening 48 as barbs 198 contact the inside of opening 48 to provide a plurality of finger-like extensions which secure baluster section 162 inside opening 48.
Similarly, rail section 164 comprises a plurality of barbs 206 on the outer periphery of cross members 208 (Figure 8). as seen in Figures 9 and '11, barbs 206 are positioned opposite in direction as compared to barbs 198. This orientation of barbs 206 facilitates the securing of rail member 164 inside opening 52 of lower rail 18.
ps depicted in Figure 12, each crass member 200 of baluster section 162 also includes angled section 210 (also depicted in Figure 11 ), which provides a top region of smaller diameter as compared to the diameter of the rest of baluster section 162 at cross members 200. This facilitates insertion of baluster section 162 into opening 48 of baluster 14.

Detailed Description of the Preferred Embodiments) Referring initially to Figures 1 and 1A, railing system 10 is shown adjacent stairway or set of stairs 12. Railing system 10 includes balusters 14 interposed between upper rail 16 and lower rail 18.
Stairway 12 includes a pair of parallel-spaced opposed stringers 20 and 22 attached at an upper end to beam 24. Lower ends of stringers 20 and 22 rest on a support surface (not shown). A plurality of tread members 26 are positioned horizontally on corresponding plurality of vertical support sections 27 of stringers 20 and 22.
A typical stairway 12 has a 7 inch rise 30 and a 11'/4 inch run 32 which is equivalent to a rise angle 28 from a horizontal support surface of about 3.2.5 degrees.
Railing system 10 includes upper post 34 and lower post 36. Upper post 34 is secured to a top face 38 of beam 24 and lower post 36 is attached to, or rests on, the support surface and is attached to a lower region of stringer 22. Lower post 36 may further be attached to the lowermost tread member 26 at notch 40. Upper and lower rails 16 and 18 are positioned between the posts 34 and 36 and extend downwardly from upper post 34 to lower post 36 at an angle of about 32.5 degrees from the horizontal so as to correspond with rise angle 28 of stairway 12. Upper and lower rails 16 and 18 have parallel ends which are cut at an angle of about 32.5 degrees from that perpendicular to the longitudinal axis of rails 16 and 18 which also corresponds to the rise angle 28.
VUhen railing system 10 is assembled adjacent stairway 12, rails 16 and 18 are attached to a side of posts 34 and 36 so that the ends of rails 16 and 18 lie flush with adjacent sides of posts 34 and 36. This ensures that the angle of rails 16 and 18 from the horizontal, that is angles 80 and 82 shown in Figure 2A, correspond to rise angle 28 ensuring that rails 16 and 18 are positioned generally at are angle from the horizontal corresponding to rise angle 28 of stairway 12.
A plurality of balusters 14 are interposed between rails 16 and 18 and are rigidly secured between those rails in a vertical orientation, while rails ~ 6 and 18 are oriented at an angle from the horizontal as discussed above. Referring to Figures 1A
and 2A, in order to provide for a vertical orientation of balusters 14 in conjunction with rails 16 and 18 which are angled from the horizontal by angles 82 and 80, retaining members 42 are employed to attach balusters 14 to rails 16 and 18. Upper face 44 of rail 18 includes a plurality of openings 46 extending laterally into face 44, representing a side of rail 18, in a direction perpendicular to face 44 also perpendicular to the longitudinal axis of rail 18.
Retaining member 42 fits within opening 46 and includes rail section 64 which is dimensioned in width with respect to the width of opening 46 to provide a friction fit engagement within opening 46. Baluster 14 includes opening 48 in an end of baluster 14 into which baluster section 62 of retaining member 42 may be inserted.
Baluster section 62 of retaining member 42 is dimensioned in width with respect to opening 48 to provide a friction fit engageme~lt with opening 48 into which baluster section retaining member 42 is inserted. This is best seen in Figure 2A.
As best depicted in Figures 2 and 2A, upper rail 16 includes a lower face 50 into which a plurality of openings 52 are formed. Openings 52 extend laterally into face 50 and thereby into one side of rail 16. Openings 52 are of the same diameter and length as openings 46. Openings 52 extend in a direction perpendicular to face 50 and perpendicular to the longitudinal axis of rail 16. Rail section 64 of retaining member 42 and opening 52 are dimensioned to provide a friction fit engagement of rail section 64 within opening 52. Baluster 14 includes an opening (not shown) at its upper end 54, similar to opening 48 in lower end 56 of baluster 14 as described above.
Baluster section 62 of retaining member 42 and the opening in end 54 are dimensioned fio provide a secure friction fit engagement of baluster section 62 of member 42 within the opening at end 54.
Ends 54 and 56 are cut at an angle from the longitudinal axis equal to rise angle 28 of about 32.5 degrees and are parallel with one another. This ensures that upper face 58 and lower face 60 are coplanar with faces 50 and 44, respectively. Lower face 60 is shown in its assembled position coplanar with face 44 in Figure 1A.
Referring to Figures 3, 4, 5, and 6, retaining member 42 is depicted in perspective, side, front and rear views. Retaining member 42 includes baluster section 62 integrally joined to rail section 64. Baluster section 62 includes four ribs 56 oriented at right angles to one another and extending the length of baluster section 62. Ribs 66 are integrally joined with four ribs 68 oriented at right angles with respect to one another of rail section 64. Ribs 68 of rail section 64 are wider than ribs 66 providing a larger diameter 70 as compared to diameter 72 of baluster section 62 (best seen in Figure 4).
UVhile not shown, ribs 66 may be tapered with a larger diameter adjacent ribs 68 to provide a general frusto-conical outer periphery to facilitate insertion of baluster section 62 into baluster 14.
As best seen in Figure 4, rail section and baluster section .are angled with respect to one another at angle 74 which is equivalent to rise angle 28 of ataout 32.5 degrees.
~lllhen rails 16 and 18 are oriented at an angle from the horizontal at angles 82 and 80, respectively, of about 32.5 degrees, rail section 64 may be inserted into opening 46 or opening 52 with baluster section 62 oriented in a vertical direction (see Figure 1A). As depicted in Figure 2A, retaining member 42 is inserted into opening 52 so that baluster section 62 faces vertically as is baluster section 62 of retaining member 42 positioned within opening 46 of rail 18. This properly orients baluster 14 in a vertical position as depicted in Figures 1 and 2 when attached to both baluster sections 62 of retaining members 42.
Rail section 64 is dimensioned at diameter 70 which is generally equivalent to diameter of openings 46 and 52 to provide a friction fit of rail section 64 within either one of openings 46 or 52. As well, the length 76 of rail section 64 is equal to the depth of openings 46 and 52. As best seen in Figures 3 and 4, because ribs 68 are of larger diameter 70 as compared to diameter 72 of ribs 66, lip 78 is formed at the inner end of ribs 68 where ribs 68 merge with ribs 66. Lips 78 on ribs 68 are in coplanar alignment with each other as ribs 68 are all of equal length 76.
Length 76 is equal to the depth of openings 46 and 52 and when rail section 64 is 5 positioned within opening 46 or opening 52 with rail section 64 contacting the end of opening 46 or opening 52, lips 78 are in coplanar alignment with the plane of corresponding face 44 or 50. As a consequence, when baluster section 62 is positioned within one of opening 48 or opening in end 54 of baluster 14, lips 48 act as a stop contacting corresponding face 58 or 60 which rests against lip 78, as best depicted in 10 Figure 1A. This provides additional support to balusters 14 which contacts lips 78, rather than faces 44 or 50 which are generally made of wood or other soft material, softer than material used to construct retaining members 42.
As well, because retaining members 24 have rail section 64 which is positioned at angle 15 74 with respect to baluster section 62, equivalent to angles 80 and 82 of rails 18 and 16, balusters 14 are oriented in a vertical position.
The foregoing description of a preferred embodiment has been directed to the most popular rise and run angle of a stairway, namely a 7 inch rise and an 11 %4 inch run, resulting in about a 32.5 degree angle from the horizontal. However, other stair angles may also be accommodated and will similarly provide a 'vertical baluster interposed between rails angled from the horizontal by changing the predetermined angle of the retaining member 42. For example, other popular stair runlrise ratios are: (i) a rise of 6 112 inches and run of 11 inches, resulting in a rise angle of about 30 degrees; (ii) a rise of 7'h inches and run of 10 inches resulting in a rise angle of about 36 degrees; and a rise of 7'/e inches and a run of 10'/4 inches resulting in a rise angle of about 35 degrees. By providing a predetermined angle 74 and positioning rails 16 and 18 at angles 82 and 80 equivalent to 30 degrees a rise of 6 112 inches and a run of 11 inches can be accommodated. Similarly, a rise of 7'/2 inches and a run of 10 inches can be accommodated by providing angles 74, 82 and 80 of 36 degrees and a rise of 7 %4 and run of 10'/4 accommodated by providing angles 74, 82 and 80 of 35 degrees.
An alternate embodiment of the invention will now be discussed with reference to Figures 7-12. This embodiment provides an alternate retaining member 142 which incorporates buffer section 190 which is angled thereby obviating the need to cut upper end 54 and lower end 56 of baluster 14 at an angle different frorn that perpendicular to the longitudinal axis of baluster 14.
Retaining member 142 also separates baluster 14 from rails 16 and 18 to prevent copper induced corrosion of baluster 14 caused by the copper in the preservative commonly found in rails 16 and 18. As depicted in figure 1A, use of retaining member 42 of the first embodiment discussed above causes contact between lower face 60 of baluster 14 and upper face 44 of lower rail 18~ Although not shown, similar contact will occur between upper face 58 of baluster 14 and lower face 50 of upper rail 16.
Referring to Figures 7 and 8, retaining member 142 is a perspective view with Figures 7 viewed facing baluster section 162 and Figure 8 viewed facing rail section 164. Buffer section 190 is positioned between sections 162 and 164 arid joins sections 162 and 164 together.
Buffer section 190 has a cylindrical outer periphery with a wedge shaped cross-section.
Baluster section end face 192, sometimes referred to as a first face, forms a first end attached to baluster section 162, seen best in Figures 7 and 10. Rail section end face 194, sometimes referred to as a second face, forms a second end attached to rail section 164, seen best in Figure 8.
Referring to Figure 9, a plane defined by face 192 is oriented with respect to a plane defined by face 194 at angle 196, equal to a predetermined angle which will orient baluster 14 vertically when attached to lower rail 18 when rail 18 is positioned adjacent a stairway or set of stairs 12. The predetermined angle may be iaetween 30 degrees and 36 degrees and preferably is about 32.5 degrees when use adjacent a stairway 12 having a 7 inch rise 30 and 11 1/4 inch run 32 (Figure 1 ).
Retaining member 142 includes rail section 164 which is dimensioned in width with respect to the width of opening 52 to provide a friction fit engagement with opening 52.
Retaining member 142 also includes baluster section 162 which is dimensioned in width to provide a friction fit engagement with opening 48 of baluster 14.
Face 192 is planar and is dimensioned to contact baluster 14 when baluster section 162 is inserted in opening 48 as depicted in Figure 9. Face 192 prevents baluster 14 from moving past baluster section 162 in the direction of rail section 154.
Referring to Figure 8, face 194 has a diameter larger than the diameter of opening 52 to contact upper face 44 of lower rail 18 when rail section 164 is inserted into opening 52 to prevent retaining member 142 from entering opening 52 past rail section 164.
It should further be noted that, as depicted in Figure 9, the bottom end of baluster 14 is cut perpendicular to the longitudinal axis of baluster 14 due to the interposing of buffer section 190 between baluster section 162 and rail section 164 and the positioning of faces 192 and 194 with respect to each other at angle 196. As well, buffer section 190 separates the bottom end of baluster 14 from upper face 4.4 of lower rail 18 preventing contact between baluster 14 and rail 18 to reduce the effect of any copper induced corrosion on baluster 14.
Referring to Figures 11 and 12, ~~retaining member 142 is shown in a cross-section view.
In order to improve the securing of baluster section 162 into opening 48 a plurality of barbs 198 are provided at the outer edge of each cross member 200 (Figure 7).
Barb 198 is shown in close up in Figure 12 and comprises elongated sloped section connected to lateral section 204. Lateral section 204 is positioned closer to buffer section 190 as compared to sloped section 202. As best seen in Figure 9, this provides additional means of securing baluster 14 in opening 48 as barbs 198 contact the inside of opening 48 to provide a plurality of finger-like extensions which secure baluster section 162 inside opening 48.
Similarly, rail section 164 comprises a plurality of barbs 206 on the outer periphery of cross members 208 (Figure 8). as seen in Figures 9 and '11, barbs 206 are positioned opposite in direction as compared to barbs 198. This orientation of barbs 206 facilitates the securing of rail member 164 inside opening 52 of lower rail 18.
ps depicted in Figure 12, each crass member 200 of baluster section 162 also includes angled section 210 (also depicted in Figure 11 ), which provides a top region of smaller diameter as compared to the diameter of the rest of baluster section 162 at cross members 200. This facilitates insertion of baluster section 162 into opening 48 of baluster 14.
Having thus described preferred embodiments of a railing system for a stairway and a baluster retaining member, it wilbe apparent by those skilled in the art how certain advantages of the present invention have been achieved. It should also be appreciated that various modifications, adaptations, and alternative embodiments thereof may be made within the scope and spirit of the present invention. For example, while specific angles associated with certain run/rise ratios have been described, it should be apparent that the inventive concepts described above would be equally applicable to any number of different rise/run ratios by making appropriate adjustment to angles 74, 82 and 80, consistent with rise angle 28. Moreover, the words used in this specification to describe the invention and its various embodiments are to be understood not only in the sense of their commonly defined meanings, but to include by special definition in this specification structure, material or acts beyond the scope of the commonly defined meanings. Thus, if an element can be understood in the context of this specification as 5 including more than one meaning, then its use in a claim must be understood as being generic to all possible meanings supported by the specification and by the word itself.
The definitions of the words or elements of the following claims are, therefore, defined in this specification to include not only the combination of elements which are literally set forth, but all equivalent structure, material or acts for performing substantially the same 10 function in substantially the same way to obtain substantially the same result. The described embodiments are to be considered illustrative rather than restrictive. The invention is further defined by the following claims.
