DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION
FIG. 1 is a perspective view of a handrail and bracket assembly according to one embodiment of the present invention. The handrail and bracket assembly is shown attached to a wall W. The handrail and bracket assembly of this embodiment generally includes a rail 10 and a pair of brackets 20. Rail 10, in the embodiment shown, is a tubular member of generally circular cross-section. Rail 10 may be formed in any shape desired for the particular application. Additionally, the cross-section of rail 10 need not be circular, but can take on any number of shapes desired. Rail 10 should be manufactured from a material suitable to withstand the load conditions for its intended use. For example, depending on the environment, rail 10 can be made of stainless steel, aluminum, plastic, or other materials.
Each bracket 20 (FIGS. 2 and 3) generally includes a base 30, a first wall 40, a second wall 50, a first channel 60, a second channel 70, a cap 80, a fastener 90, a biasing means 100 and a cover 110. Base 30, in the embodiment shown, is a generally rectangular member including a first or front surface 31, a second or rear surface 32, a first edge 33, a second edge 34, a third edge 35 and a fourth edge 36. In the embodiment shown, a pair of mounting holes 37 extend through first surface 31 and second surface 32 (FIG. 4). Note that mounting holes 37 are located nearer first wall 40 than second wall 50.
First wall 40 extends from first surface 31 of base 30 and is generally perpendicular thereto. First wall 40 includes a first or exterior surface 41, a second or interior surface 42, a first or front edge 43 and a second edge 44.
Similarly, second wall 50 includes a first or exterior surface 51, a second or interior surface 52, a first or front edge 53 and a second edge 54. Second wall 50 further includes a pair of holes 55 for attaching cover 110, as described below. Second wall 50 also extends from and is generally perpendicular to first surface 31 of base 30.
First channel 60 extends between first wall 40 and second wall 50 and includes a lower surface 61, an underside 61A, an open top 62 and a central longitudinal axis 63. Axis 63 is perpendicular to first surface 31 of base 30 and parallel to second surface 42 of first wall 40 and second surface 52 of second wall 50. Note that first channel 60 is located such that axis 63 is located nearer second wall 50 than first wall 40. Channel 60 is configured to receive rail 10, as described below.
Second channel 70 includes a lower surface 71 and an open top 72. Second channel 70 further includes a central longitudinal axis 73. Axis 73 is located nearer front edges 43 and 53 of first wall 40 and second wall 50 than it is near first surface 31 of base 30. Axis 73 extends perpendicular to axis 63 of first channel 60. Channel 70 is configured to receive rail W, as described below.
Referring to FIGS. 4 and 5, bracket 20 includes a lip L extending around the interior of bracket 20 along surfaces 31, 41, 51 and underside 61A of channel 60 as shown. As described below, lip L limits the movement of cover 110 and positions it for attachment to second wall 50.
Bracket 20 further includes a cap 80 that engages rail 10 as described below. Cap 80 includes a first or top surface 81, a second or bottom surface 82, a first edge 83, a second edge 84, a third edge 85 and a fourth edge 86. A recess 87, which conforms to the outer surface of rail 10, is formed in bottom surface 82 and extends from third edge 85 to fourth edge 86. An opening 88 extends through first surface 81 and second surface 82 of cap 80.
Fastener 90, in the embodiment shown, is a bolt that includes a shaft with a first portion 91 and a second, threaded portion 92. Fastener 90 further includes a head 93 and a nut 94. Head 93 is shaped to mate with opening 88, as described below. Biasing means 100, in the embodiment shown, is a coil spring. Spring 100 is placed around the shaft of fastener 90 as described below.
Cover 110 is a generally L-shaped member including a first leg 111 and a second leg 112. A recess 113 is formed in second leg 112 and corresponds to the shape of first channel 60. A pair of bosses 114 are formed, respectively, on first leg 111 and second leg 112. Bosses 114 include openings 115 extending as shown. Cover 110 fits between first wall 40 and second wall 50, as described below.
To assemble the rail 10 and bracket 20, one end of rail 10 is placed in channel 60 such that an opening (not shown) extending through rail 10 is aligned with opening 64 in channel 60. Cap 80 is then placed on rail 10 such that rail 10 rests within recess 87. Fastener 90 is then inserted through opening 88 in cap 80, the opening in rail 10, and opening 64 such that shaft 91 including threaded portion 92 extends between first wall 40 and second wall 50. Biasing means 100 is then placed around fastener 90 and nut 94 is threaded onto portion 92 to retain biasing means 100 in place and to retain bracket 20 on rail 10. A second bracket 20 is attached to the opposite end of rail 10 in the same manner.
Once brackets 20 have been secured to rail 10, the combined handrail and bracket assembly may be mounted to wall W. To do so, the brackets are positioned in the desired location and screws or other fasteners are inserted through openings 37 in base 30 to secure brackets 20 and rail 10 to wall W. Note that because channel 60 is offset so as to be closer to second wall 50 than first wall 41 and openings 37 are offset so as to be closer to first wall 40 than second wall 50, brackets 20 may be assembled to rail 10 before being attached to wall W. If both channel 60 and openings 37 were centered with respect to walls 40 and 50, brackets 20 would have to be attached to wall W before rail 10 could be attached to brackets 20. Otherwise, fastener 90 and biasing means 100 would block access to openings 37.
Once rail 10 and brackets 20 have been secured to wall W, cover 110 is secured to each bracket 20. This is accomplished by inserting cover 110 between walls 40 and 50 until it engages lip L. In this position, openings 55 in second wall 50 are aligned with openings 115 in cover 110. Screws or other fasteners are then inserted through openings 55 and 115 to secure cover 110 in place.
FIGS. 10–13 show the movement of rail 10 from an expanded or in-use position to a collapsed or stored position. FIG. 10 shows a front elevational view of rail 10 and brackets 20 attached to wall W with rail 10 in the expanded or in-use position. In this position, rail 10 rests against lower surface 61 of each channel 60. Biasing means 100 extends between the underside 61A of each channel 60 and nut 94. Note that in this position, biasing means 100 biases rail 10 into channel 60 by exerting a force between undersurface 61A and nut 94. This urges nut 94 downwardly which in turn pulls down on fastener 90 and cap 80. FIG. 11 shows rail 10 lifted out of channel 60 and ready to be moved to the collapsed position. Note that as rail 10 is raised, it lifts caps 80 which in turn raise fasteners 90 and nuts 94, thereby compressing biasing means 100 between nuts 94 and undersides 61A of channels 60. Once in this position, rail 10 can be rotated as shown in FIG. 12. Once rail 10 has been rotated such that it is positioned above channel 70, rail 10 can be lowered and is now in a collapsed or stored position adjacent wall W. Note that in this position biasing means 100 biases rail 10 into channel 70.
Although the present invention has been shown and described in detail, the same is for purposes of providing examples only and is not intended to limit the scope of the invention. Various changes and modifications can be made to the embodiments described without departing from the spirit of the invention. Accordingly, the scope of the invention is to be limited only by the terms of the attached claims.
