DETAILED DESCRIPTION
A handrail mounting assembly can be easily adjusted and assembled. The invention will be described relative to certain illustrative embodiments, though the invention is not limited to the embodiments described herein.
FIG. 1 shows a handrail mounting assembly 12 for mounting a handrail (not shown) to a post 10 or other support structure. The handrail mounting assembly 12 comprises an adjustable bracket 20, a bracket arm 40 extending from the adjustable bracket 20 and a handrail seat 60 for receiving a handrail to connect the handrail to the post 10. In one embodiment, the adjustable bracket 20 is configured to attach to a square post, thought the invention is not so limited. The bracket 20 can be easily adjusted, as described below. The orientation of the bracket arm 40 can also be adjusted relative to the bracket to allow adjustment of the handrail.
Referring to FIGS. 2-4, the illustrative adjustable bracket 20 comprises a first section 22 that mates with a second section 32 to attach to a post or other support structure. The illustrative first section 22 forms an open seat 18 for the post, comprising a base wall 23, and two side walls 24, 25 extending substantially perpendicular to the base wall 23. Each side wall 24, 25 includes two openings for a total of four openings, two of which, 26, 27 are shown in FIG. 2, for receiving fasteners. The openings 26, 27, are entirely contained within the side walls 24, 25 and are preferably centered between outer and inner surfaces defining the side walls, and are parallel to the inner surfaces 64, 65 of the side walls. The inner surfaces 64, 65 sandwich the post 10 when the bracket is mounted to the post 10. The illustrative side walls 24, 25 are straight and parallel to each other, as are the openings 26, 27. The openings extend into the side walls 24, 25 by a selected distance from the front face 28.
In one embodiment, the width Wb of the first section, the distance between side walls 24, 25, is about equal to the width Wp of the post 10 to allow the post to slide into the space between the side walls. The depth Db of the bracket seat 18 formed between the side walls is approximately equal to or smaller than the depth Dp of the post.
The base wall 23 also includes an opening 21, which may be a tapped through hole, for connecting the bracket 20 to the bracket arm 40.
The illustrative second section 32 comprises an end plate that spans the opening 18 formed between the two side walls 24, 25. The end plate 32 includes four openings 36, 37, 38, 39 that align with the side wall openings 26-27 to form passageways for receiving a fastener to secure the end plate 32 to the bracket seat 22. On the back side, the openings may be countersunk to accommodate the head of a fastener. The illustrative second section 32 is substantially planar, though alternatively, the second section may have a different shape, such as a u-shape with side walls that match the side walls of the first section.
In one embodiment, the openings 36-39 are slightly larger than the openings 26, 27 in the first section 22.
To mount the bracket 20 to the post 10, the first section 22 is wrapped around the post. The, the second section 32 is placed over the post 10 with the openings 26, 27, 36-39 aligned to surround the post 10. Fasteners, such as screws, are inserted into the passageways to connect the first section 33 to the second section 32. The bracket 20 can be easily adjusted on the post by loosening the fasteners, and the bracket can be secured in place and by tightening the fasteners to lock the post 10 in the bracket seat 18.
Referring back to FIG. 1, the bracket arm 40 comprises a first section 41 and a second section 42 extending at an angle, shown as perpendicular, to the first section 41. The first and second sections may be integral or separately-formed components. The first section comprises a tubular barrel including an opening 44 extending therethrough for a fastener 43 to connect the bracket arm 40 to the adjustable bracket 20. The opening 44 has a seat at a first end of the tubular barrel to limit movement of the fastener 43. The fastener 43 is longer than the opening 44 so that when the fastener head is seated in the seat of the opening 44, the tip of the fastener 43 protrudes from the second end of the first section 41. The protruding end of the fastener is inserted in the opening 21 in the bracket base wall 23 to connect the bracket arm 40 to the bracket 20. The second section 42 of the bracket arm 40 forms a handrail seat connector to connect the handrail seat 60 to the bracket arm 40.
The orientation of the bracket arm 40 relative to the bracket 20 is adjustable. The bracket arm 40 can rotate about the protruding end of the fastener, allowing orientation of handrail seat. After the bracket arm 40 is position in a desired orientation relative to the bracket 20, the fastener 43 is tightened to lock the bracket arm 40 to the bracket 20 in the desired orientation. The fastener 43 can be loosened, and the orientation of the bracket arm changed, followed by re-tightening of the fastener 43 to change the orientation of the bracket arm 40.
The illustrative handrail seat 60 is formed on the top of the second section of the bracket arm 40 and can be integral with the bracket arm 40 or separately-formed and attached. The handrail seat 60 is curved to match the profile of the bottom of a handrail and includes openings 62, 63 to receive fasteners for fastening the rail to the handrail seat 60. The handrail seat can have any suitable configuration for receiving and connecting a handrail to the bracket arm. For example, the handrail seat could be annular, or square to accommodate a square handrail. The handrail can be adjustable relative to the bracket arm 40, if desired.
The illustrative handrail mounting assembly provides increased flexibility and reduced installation time by eliminating the need to drill, tap or punch openings in the post or other support structure in order to mount the handrail. The illustrative handrail mounting assembly allows for easy field adjustment of the assembly and-or handrail mounted thereto by simply loosening the components, adjusting and re-tightening the connections in the desired location and orientation.
The scope of the claims is not meant to be limited to the details of the described exemplary embodiments.
