TECHNICAL FIELD
The present disclosure relates generally to mounting systems for hand rails.
BACKGROUND
It is conventional to mount hand rails along stairs, ramps, walk ways, and similar pedestrian thoroughfares to provide a secure grab point for a person transiting through the space. When hand rails are mounted to walls or other existing structures, the spacing of the supports may be irregular, making it difficult to use standard or common length rails to extend between the supports. Alternatively, the spacing of the supports may be regular and consistent along the thoroughfare but the spacing may not match up to standard length rails sections. Further, while the planning spacing may be regular enough to permit the pre-cutting of rails for installation, the reality of the installation may not match the plans and the pre-cut sections may not fit the installation.
These scenarios typically call for the cutting of rail sections in the field to match the particular needs and requirements of an installation. Conventional supports have exposed the cut ends of the rails sections, requiring that the cut ends also be dressed and cleaned in the field. For some materials and some installations, there may also be a need to renew rust- or weather-proofing of the cut ends as well. To ensure that the cuts are cleanly and consistently executed, a more elaborate saw or cutting system may be needed in the field. Welding may also be required to fasten lengths of railing together, and these welds would also need to be similarly dressed and possibly weather-protected.
To ensure that the rails meet closely enough for welding or to avoid any unsightly gaps between rails, precision in the cutting of the rails may also require additional labor or more highly skilled labor for installation.
It is a further issue that replacement of installed rails may require similar high levels of precision and skill, as well as new dressing of any joints or welds between rails.
Improvements to the conventional systems and other known approaches to installing and repairing hand rails are desirable.

DETAILED DESCRIPTION
Reference will now be made in detail to exemplary aspects of the present invention which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
FIG. 1 illustrates a new hand rail mounting system 100 with a barrel 102 within which a hand rail 104 may be inserted into each end. As shown hand rail 104 is a hollow tubular hand rail but other types of hand rails will be discussed below and are within the scope of the present disclosure. Hand rail 104 may be secured within barrel 102 by an internal clamp 106 that is drawn into securement with hand rail 104 by one or more screws or threaded fasteners 108 that may extend upward through the barrel. Clamp 106 is preferably formed or shaped to have an outward rounded surface 105 that is shaped to generally match the shape of an inner wall surface 160 of rail 104 to ensure sufficient engagement between clamp 106 and rail 104. Clamp 106 may also define an inward rounded surface 205 opposite outward rounded surface 105.
Supporting barrel 102 and hand rail 104 may be one or more supports to that extend to the wall to which the hand rail is to be attached. A vertical support 110 may be positioned underneath barrel 102 and may be connected to a horizontal support 112 that extends toward a wall to which support system 100 may be mounted. A bracket hub 114 may be connected to a second end of horizontal support 112 to assist in connection of system 100 to the wall. In addition, a first backing or support disk 124 (shown in FIGS. 25, 26 and 31) may be mounted between bracket hub 114 and the wall and a second backing or support disk 126 (shown in FIGS. 27, 28 and 31) may be mounted to an opposite of the wall to spread any load applied to the hand rail over a larger portion of the wall. Such disks may be desired or required when the wall is made of a material, such as but not limited to glass, where a concentrated load may cause failure of the material in the area around the bracket hub.
FIGS. 2 to 5 further illustrate barrel 102 and clamp 106 for use with system 100. Barrel 102 may include a single center mounted screw or fastener opening 116. A single clamping screw or fastener 118 (shown in FIG. 1) may be extended upward through vertical support 110 and engage clamp 106. Tightening screw 118 will draw the clamp 106 down with outward surface 105 engaging an inner wall of rail 104 and securing the rail to the barrel. Screw 118 will also connect vertical support 110 to barrel 102. As shown in FIG. 1, vertical support 110 engages horizontal support 112 and a set or lock screw 120 may be used to releasably lock the two supports to each other.
Horizontal support 112 may be slidably received within a central opening of bracket hub 114 and a set screw 122 may be used to secure support 112 within the central opening of the bracket hub. This slidable relationship permits the rail to be aligned linearly regardless of variations in the wall to which the rail is attached.
FIGS. 2 to 5 illustrate barrel 102 and clamp 106. Barrel 102 may include opposite ends 162 and 164 for receiving ends of rails 104 with an interior 166 extending generally between the ends. Interior 166 is preferably sized and configured to generally closely match the size and shape of an outer shape of rail 104 (or other rails that may be held within a rail mounting system according to the present disclosure). Within interior 166 is defined an inner wall 168.
It may be preferable to have clamp 106 extend further than the length of barrel 102 to ensure more engagement between the clamp and rail 104. With the clamp hidden within the interior of rail 104, the extra length of the clamp would be invisible once the rail and support system are installed. Clamp 106 may have one or more openings 107 for fasteners such as screw 108 to engage the clamp and draw the clamp into engagement with rails 104. To aid in ease of installation, openings 107 may be threaded to match threads of screw 108. Alternatively, a separate nut may be used above clamp 106 to receive and engage screw 108 and exert clamping pressure on rails 104.
The ends of rail 104 would be preferably completely or mostly enclosed enclosed within barrel 102, and the length of barrel 102 provides some margin for error in the cutting of rail 104. By having the ends of rail 104 completely within the barrel, the cut ends of the rail would not have to be finished. The clamp within the barrel would also secure the ends of the rail with respect to each other so that the ends would not have to welded to each other. Having a length of rail 104 within clamp 102 will also permit some lateral movement of rail 104 with regard to clamp 102 will also allow for expansion and contraction of the structure or the railing system due to weather variations, building settling or movement, or other gradual changes. This overlapping may also permit the railing system to resist being pulled apart during a more dramatic movement event, such as an earthquake.
FIGS. 6 to 17 illustrate further alternatives for barrels and clamps according to the present disclosure. These designs include a pair of fastener openings permitting different supports illustrated in FIG. 29. FIGS. 6 to 9 illustrate an alternative embodiment barrel 302 and clamp 306. Barrel 302 is generally configured similarly to barrel 102 with a pair of openings 116, each configured to receive a screw 108. Clamp 306 is configured generally similarly to clamp 106 with a pair openings 107, each configured to engage a screw 108.
FIGS. 10 and 11 illustrate a further embodiment of a barrel 402 for use with a rail mounting system according to the present disclosure. Barrel 402 differs from barrel 302 primarily with regard to the spacing of openings 116. Other structural elements of the barrels are essentially the same.
FIGS. 12 and 13 illustrate a further embodiment of a clamp 406 for use with a rail mounting system according to the present disclosure. Clamp 406 differs from clamp 306 primarily with regard to the spacing of openings 107. Other structural elements of the clamps are essentially the same.
FIGS. 14 and 15 illustrate a still further embodiment of a barrel 502 for use with a rail mounting system according to the present disclosure. Barrel 502 differs from barrel 302 primarily with regard to the spacing of openings 116. Other structural elements of the barrels are essentially the same.
FIGS. 16 and 17 illustrate a further embodiment of a clamp 506 for use with a rail mounting system according to the present disclosure. Clamp 506 differs from clamp 306 primarily with regard to the spacing of openings 107. Other structural elements of the clamps are essentially the same.
FIGS. 18 and 19 illustrate vertical support 110 with an opening 111 through which screw 118 may extend to aid in the clamping of rails 104 to barrel 102.
FIGS. 20 to 22 illustrate horizontal support 112 with an opening 113 for receiving vertical support 110 and including an set screw opening 130 for receiving set or lock screw 120 to secure the vertical support at the desired height. On an end opposite opening 130 may be a second opening 132 for receiving a fastener for securing horizontal support 112 to bracket hub 114.
FIGS. 23 and 24 illustrate bracket hub 114 with an opening 123 to receive set or locking screw 122 to secure horizontal support 112 within a support opening 116. Opening 116 may further have a fastener opening 118 to receive a larger fastener extending from the structure or wall to which the hand rail mounting system 100 may be secured.
FIGS. 25 and 26 illustrate a first backing disk 124 that may be positioned between the bracket hub and the wall to which the rail is to be mounted.
FIGS. 27 and 28 illustrate a second backing disk 126 that may be positioned on an opposite side of the wall to which the rail may be mounted.
FIGS. 30 to 32 illustrate a system 100 with an alternative rail 150 that includes a channel underneath for receiving a variety of lights or other elements that may be desired as part of a hand rail. Each rail 150 includes an engagement end 152 that is intended to be inserted within barrel 102. As shown in FIGS. 31 and 32, system 100 is configured differently from the assembly shown in FIG. 1 to conform to the shape of rail 150. Where rail 104 had a generally continuous interior, rail 150 includes a lower channel 200 with a wall 202 extending into an interior of rail 150. Clamp 106 may be sized and shaped so that clamp 106 fits within the open end of rail 150 above wall 202. Note that clamp 106 has been rotated halfway so that outward rounded portion 105 of clamp 106 is up. In this configuration, inward round portion 205 is positioned to engage wall 202 when screw 108 draws the clamp into engagement with the rail. When screw 118 is rotated to draw clamp 106 into engagement with rail 150, the clamp engages wall 202 rather than
FIGS. 33 and 34 illustrate a first alternative embodiment of a wall support and connection system 152 that includes a pair of clamping screws 118 for use with the alternative embodiments of the barrels and clamps illustrated in FIGS. 6 to 17.
FIGS. 35 to 36 illustrate a second alternative embodiment 154 of a support that may be configured to mount the rail to a top of a wall and may also permit the mounting of the rail in an angled fashion by having a pivoting connection between the support and the barrel.
