Abstract
A railing system comprising a first longitudinal rail portion defining a channel into which pickets are insertable at spaced intervals. Fasteners are used to pivotally connect the pickets to the channel for orientation to a desired angle with respect to the first longitudinal rail portion. A second longitudinal rail portion is fittable onto the first longitudinal rail portion to form an assembled rail member in which the channel and fasteners are concealed within the interior of the assembled rail member. The railing system provides a simple and efficient way to install railings, and is particularly suited for assembly of railings at an incline to the horizontal.
Description
FIELD OF THE INVENTION
This invention relates to railing system useful to form a barrier, fencing or the like. In particular, the invention relates to a railing system in which the pickets are readily adjustable to an angle with respect to the railing to allow forming of a barrier on a horizontal or on an inclined surface.
BACKGROUND OF THE INVENTION
Fencing and balustrades formed using a top railing supported by pickets or upstanding posts are commonly used on stairs, balconies and patios as a safety barrier with a pleasing appearance. They may be formed of materials such as wrought iron, vinyl, wood or aluminum. Aluminum is generally the preferred material. Aluminum is easy to extrude and form and is lightweight yet sturdy and enjoys excellent weather resistance.
The fencing or balustrade is typically formed as a railing system that includes a top railing secured to pickets that extend vertically downwardly from the top rail and which are spaced at desired intervals. The pickets may extend into a wooden or concrete base or the like, or, more usually are also attached to a bottom rail which, in turn, is mounted to the stairs or balcony for which the railing system acts as a barrier.
Examples of prior art railing systems include U.S. Pat. No. 4,968,005 to Zen and U.S. Pat. No. 5,200,240 to Baker.
In the installation of railing systems, particularly when the top railing is installed at an incline to the horizontal on stairs or sloped surfaces, for example, the problem of attaching the pickets to the top and bottom rails can result in considerable delay and in wastage of material. The conventional method of joining the pickets to the top and bottom rails is by welding. When the railings are inclined to the horizontal, it is necessary to measure the required angle and cut the ends of the pickets to the correct angle and length. If errors are made in transferring the measurements to the pickets then substantial waste can result. U.S. Pat. No. 4,125,249 to Zen discloses one solution to this problem by providing a railing structure having pivotable joints to mount the pickets to the railings for rotation to a desired angle to minimize wastage and maximize speed of construction.
SUMMARY OF THE INVENTION
The present invention provides a railing system and railing member that also allows pivoting of the pickets with respect to the railing to simplify installation. The arrangement of the present invention conceals the pivoting attachment of the pickets to the railings to provide an aesthetically pleasing appearance.
Accordingly, the present invention provides a railing system comprising:
a first longitudinal rail portion defining a channel into which pickets are insertable at spaced intervals;
fasteners to pivotally connect the pickets to the channel for orientation to a desired angle with respect to the first longitudinal rail portion; and
a second longitudinal rail portion fittable onto the first longitudinal rail portion to form an assembled rail member with the channel and fasteners concealed within the interior of the assembled rail member.
The present invention also provides a railing system comprising a first longitudinal rail portion to pivotally support a plurality of pickets at spaced intervals for orientation to a desired angle and a second longitudinal rail portion fittable onto the first longitudinal rail portion to form an assembled rail member with the first longitudinal rail portion concealed by the second longitudinal rail portion.
In a further aspect, the present invention provides a rail member comprising:
a first longitudinal rail portion defining a channel into which pickets are insertable at spaced intervals to be pivotally supported for orientation to a desired angle with respect to the first longitudinal rail portion; and
a second longitudinal rail portion fittable onto the first longitudinal rail portion to form an assembled rail member with the channel concealed within the interior of the assembled rail member.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1
shows a set of railings that employ the rail members and the railing system of the present invention. The railing system includes a top rail member
4
and a bottom rail member
6
each attached to a plurality of pickets
2
. Rail members
4
and
6
are inclined at an angle to the horizontal to follow the rise of stairs
7
. As will be described in more detail below, the railing system of the present invention permits pivotal adjustment of the pickets with respect to the rail members to accommodate a wide range of slopes of inclined surfaces such that the pickets remain essentially vertical while attached rail members are supported substantially parallel to the inclined surface.
It will be appreciated that the railing system of the present invention is also configurable for installation on a horizontal surface with the pickets extending at generally right angles to the rail members as shown in FIG.
2
. Top rail member
4
and bottom rail member
6
are of similar construction and include a first longitudinal rail portion
8
which defines a channel
10
into which the ends of a plurality of pickets
2
are insertable at spaced intervals. Fasteners
12
are used to pivotally connect pickets
2
in channel
10
for orientation to a desired angle with respect to the first longitudinal rail portion. A second longitudinal rail portion
14
is fittable onto first longitudinal rail portion
8
to form the assembled rail member
4
or
6
with the channel
10
and fasteners
12
concealed within the interior of the assembled rail member.
Referring to
FIGS. 2 and 3
, there is shown a perspective and cross-sectional view of top assembled rail member
4
. First longitudinal rail portion
8
includes a lower surface
16
formed with a plurality of spaced openings
18
to receive the top end of picket
2
for insertion into channel
10
. In the case of a first longitudinal rail portion formed of aluminum, each opening
18
is preferably formed by punching an appropriately shaped hole through lower surface
16
. Each opening
18
is dimensioned to accommodate the pickets for pivoting over a range of angles to the first longitudinal rail portion
8
. In the illustrated example of
FIG. 3
, pickets
2
are formed with a hollow, generally rectangular cross-section and openings
18
are elongated in the longitudinal direction of the rail portion to allow pivoting of the pickets without the picket walls interfering with the edges of the openings. It will be apparent to a person skilled in the art that pickets
2
can be formed with any regular cross-sectional shape as long as openings
18
in lower surface
16
are appropriately shaped and dimensioned. Generally, in most applications, rail members
4
and
6
are oriented in the range of 0 to about 38 degrees to the horizontal (angle α in
FIG. 1
) which requires that openings
8
be dimensioned to permit pivoting of pickets
2
in a range between about 90 degrees and about 52 degrees with respect to the longitudinal axis of the first longitudinal rail portion
8
(angle β in FIG.
1
).
First longitudinal rail member
8
is formed with a pair of spaced, upstanding side walls
20
that extend upwardly from the lower surface
16
to define channel
10
therebetween with an open top. Preferably, side walls
20
initially extend inwardly toward each other and upwardly at an angle to the lower surface and then extend upwardly in a spaced, parallel configuration.
In order to pivotally connect pickets
2
between side walls
20
, aligned pairs of openings
22
are formed in the parallel portions of the side walls to accept fasteners
12
. As best shown in
FIG. 3
, openings
22
are alignable with corresponding openings
24
formed in the side walls of pickets
2
. The various sets of openings
22
,
24
co-operate to receive a fastener
12
which is insertable through channel side walls
20
and the picket side walls to pivotally mount the pickets between the channel side walls.
FIG. 3
a
is a detail view of a preferred fastener
12
for securing of the pickets within channel
10
. The fastener is preferably formed from metal or plastic and comprises a rigid post
30
insertable through openings
22
. Post
30
has an enlarged head
32
at one end to engage with the exterior of one channel side wall and a deformable locking body
34
at the opposite end to engage with the exterior of the other channel side wall. Deformable locking body
34
comprises a tapered member that extends from a wide shoulder
36
to a narrow tip
38
with a slot
40
extending from the tip to the shoulder. Slot
40
permits constriction and one-way insertion of the tapered member through the aligned openings
22
and
24
and subsequent expansion such that shoulder
36
abuts against the channel side wall
20
. When installed in place within openings
22
and extending through picket
2
, rigid post is anchored between the side walls
20
to pivotally support picket
2
.
Referring back to
FIG. 3
, note that the initially inward angle of side walls
20
defines a recessed region on either side of side walls
20
into which head
32
and deformable locking body
34
protrude without interfering with the installation and mounting of second longitudinal rail portion
14
over first longitudinal rail portion
8
.
Preferably, first and second longitudinal rail portions
8
and
14
are press fittable together. In the embodiment of
FIG. 3
, second rail portion
14
includes depending side walls
42
with lower inwardly directed flanges
44
that are snap fitted into a longitudinal groove
45
in the side walls
20
of first longitudinal rail portion
8
. Side walls
42
cover and conceal first longitudinal rail portion
8
, the protruding ends of fasteners
12
and the pivotally secured ends of pickets
2
in channel
10
. Side walls
42
of the second longitudinal rail portion are joined by a top wall
46
that rests on the top edges of side walls
20
of the first longitudinal rail portion
8
to fully support the second longitudinal rail portion. As shown in
FIG. 3
, when used in a top rail member
4
, second longitudinal rail portion can be formed with a rounded surface
50
over top wall
46
to provide a comfortable gripping surface.
FIG. 4
is a section view through bottom rail member
6
which has substantially the same structure as the top rail structure of FIG.
3
. The second longitudinal rail portion
14
is preferably a closer fit over first longitudinal rail portion
8
in the bottom rail member
6
. Rounded surface
50
is not formed in the second longitudinal rail portion
14
. It is the top wall
46
of the second longitudinal rail portion that is formed with openings
18
to receive the lower ends of pickets
2
. Openings
18
are dimensioned to accommodate pivoting of the pickets over a range of angles to the second longitudinal rail portion and the lower ends of the pickets are supported by fasteners
12
to extend upwardly through the open top of channel
10
formed in first longitudinal rail portion
8
.
FIG. 5
is an exploded view of an alternative arrangement of the railing system of the present invention. The illustrated railing system includes an intermediate rail member
60
between top and bottom rail members
4
and
6
, respectively. It will be apparent that multiple intermediate rail members can be installed depending on the length of pickets
2
. All assembled rail members have the same basic structure as described above with a first longitudinal rail portions
8
having a channel
10
to pivotally support pickets
2
via fasteners
12
and a second longitudinal rail portion
14
that fits over the first rail member
8
. In the case of intermediate rail members
60
, both the first and second longitudinal rail portions
8
and
14
have aligned openings
18
to accommodate passage of the pickets through the assembled intermediate rail member.
Referring to
FIG. 1
, a cap member
79
is preferably attachable to the end of an assembled rail member to seal the interior of the rail member. Cap member
79
preferably comprises a sleeve fittable over the assembled rail member.
The first and second longitudinal rail portions that are fitted together to form an assembled rail member according to the present invention are preferably formed from extruded aluminum. The rail portions can be formed of other materials such as plastic. Pickets
2
are preferably also formed from aluminum so that the entire railing system provides a light weight, but sturdy arrangement that is weather resistant.
Sets of railings assembled according to the system of the present invention are maintained in the desired configuration by supporting the railing sets using conventional anchoring posts or other support or bracing surfaces such as walls, columns, building faces etc. Generally, the ends of the rail members are fastened to a bracing surface. For example, as illustrated in
FIG. 8
, the end of top rail member
4
is fastened to a vertical wall surface
84
. Cap member
79
can include a mounting surface
86
for mounting the cap member to a vertical support surface
84
such as a wall.
FIGS. 6
,
7
and
9
illustrate various preferred arrangements for connecting one set of railings constructed according to the present invention to a support surface or a second set of railings.
FIG. 6
shows a first set of railings
70
configured with an essentially horizontal assembled top railing member
4
and a second set of railings
72
configured with an angled assembled top railing member. A connection member
74
is fitted over the ends of the top rail member
4
to join the first and second sets of railings. Connection member
74
includes two sleeves
75
a
and
75
b
adapted to fit over the adjacent ends of the railing members. In order to accommodate the change in angle between the horizontal and inclined top railings members, sleeves
75
a
and
75
b
are connected by pivoting joint
76
.
FIG. 7
shows a preferred disassembled construction of joint
76
. A circular housing
78
is formed in sleeve
75
a
to rotatably receive an annular flange
82
formed on sleeve
75
b
. The walls of sleeve
75
b
are cut away in an arcuate configuration about annular flange
82
to permit the insertion of the flange into the housing and mating of the sleeves for pivoting with respect to each other in the same vertical plane. A fastener
80
extends along the pivoting axis of the joint and engages against the outer faces of the sleeves to maintain the housing and sleeve in rotatable engagement.
In a modified form shown in
FIG. 9
, connection member
74
can be used to connect a set of railings
70
to a vertical or non-vertical support surface
84
a
. In this case, sleeve
75
a
is provided to fit over the top rail member
4
of a railing set and sleeve
75
b
is modified to include end plate
89
that is mountable to a non-vertical surface
84
a
instead of being fittable over the rail member of an adjacent set of railings. Joint
76
allows for end plate
89
to be mounted to a support surface
84
oriented at substantially any angle including a conventional vertical surface.
Although the present invention has been described in some detail by way of example for purposes of clarity and understanding, it will be apparent that certain changes and modifications may be practised within the scope of the appended claims.
