SAFETY RAILING MOUNT FOR ROOF
This invention relates to a safety railing mount for a roof of a building.
BACKGROUND OF THE INVENTION
In times past when concern about safety was less developed, workers
.. on roofs simply accepted the risk of falling and carried out their tasks
without safety
harnesses or safety rails.
In more enlightened times, requirements have been set forth that all
workers at risk of falling must be protected. In many cases this is done by
harnesses
and fall restraint cables but Often this is restrictive, particularly where
there are a
number of workers in the area to be protected.
An alternative approach is to provide a safety fence around the
perimeter of the area. A number of proposals have been made to provide such a
construction. Typically this is done by constructing a full scaffolding around
the
perimeter but this is expensive and time consuming. Alternative constructions
have
been provided but often these do not provide sufficient stability.
SUMMARY OF THE INVENTION
It is one object of the invention to provide an apparatus for mounting
safety railing to a roof.

DETAILED DESCRIPTION
Figures 1 and 2 illustrate first and second embodiments of the present
invention. Illustrated is a house 1, more specifically a partial roof 3 of the
house.
Generally, house roof construction has a face plate 5 which runs along the
length of
the house. The face plate is arranged to support the soffit and fascia of the
house.
When building a home, specifically working on the roof of a house, there are
is a
danger of a worker falling off the roof. The face plate is generally a 2x6
inch length of
lumber whereby the face plate is mounted with the wide portion 7 is mounted
vertically on the house roof. The face plate is suitable secured to the house.
As illustrated in figure 1, a safety rail mount for a roof 9 is mounted to
the face plate of the roof system. Vertical posts 11 are supported by a
mounting plate
13. The posts are arranged to extend downwardly to a suitable support surface
15
such as the ground or a base plate anchored to the ground. The post has a
support
plate 17 at a bottom end 19 which allows the post to be placed on the
supporting
surface. At a top end 21 of the post is a guide rail 23 arranged to prevent
workers
CA 2900471 2018-08-03
7
from falling off the building so as to avoid the necessity for a harness
arrangement
worn by the worker.
The posts are supported vertically by the mounting plate. In a first
embodiment of the mounting plate, as illustrated in figure 3 and 4, the plate
is
arranged to mount to an outer face 25 of the face plate of the roof system.
The plate
has a horizontal section 27 which is arranged to extend horizontally from the
outer
face of the face plate. A receiving hole 29 is arranged to receive the
vertical post and
is positioned on the horizontal section such that the post is positioned
sufficient
distance from the edge of the roof allowing the post to extend downwardly to
the
ground and vertically for receiving the guard rails.
A vertical mount 31 of the mounting plate extends vertically from the
horizontal plate such that the plate can be mounted to the outer face of the
face plate.
The vertical mount has holes 33 to receive mounting bolts 35 for sufficiently
mounting
the plate to the face plate. Some of the holes can be located at the junction
between
the angle parts so as to pass through the plate into the face plate at an
angle of
roughly 45 degrees to the plate.
In a second embodiment of the present invention, as illustrated in figure
3A and 5 the mounting plate is arranged to mount to a top face 37 of the face
plate or
on top of the plywood fastened to the face plate and underneath the shingles
if
already applied. A horizontal mount portion 39 of the mounting plate extends
from the
horizontal plate of the mounting plate. The plate has a horizontal section 41
which is
arranged to extend horizontally or at small angle downwardly and outwardly
from the
CA 2900471 2018-08-03
8
outer face of the face plate. A receiving hole 43 is arranged to receive the
vertical
post and is positioned on the section 41 such that the post is positioned
sufficient
distance from the edge of the roof allowing the post to extend downwardly to
the
ground outwardly of the eavestrough, if already in place, and vertically for
receiving
the guard rails.
The horizontal mount has holes 45 to receive mounting screw fasteners
47 for sufficiently mounting the plate to the top side of face plate.
The receiving hole 43 has a recessed portion 49 turned downwardly at
the edge so that the vertical post can be inserted easily therethrough. The
plate is
arranged support the post in a vertical position preventing horizontal
movement of the
post. The hole is slightly larger than the post to allow the plate to lie at
an angle to the
post when attached to the roof deck due to the pitch of the roof.
Alternatively the
plate can be bent at an angle matching that of the deck so that the portion of
the plate
which contains the hole is located at right angles to the post.
In Figure 6 is shown the plates 13 of Figure 3 located along the
horizontal faceplate at one side of the building and along an end roof rafter
100. In
both cases the edge portion 39 of the plate is tucked under the shingles and
fastened
by downwardly extending screws into the face plate and into the roof rafter.
In both
cases the plates are inclined from the horizontal due to the pitch of the
roof. Each
plate is associated with a respective vertical post extending to the base
plate at the
ground and two or more horizontal rails are applied to the portion of the post
above
the plate.

The mounting plate consists of an integral plate and is formed from a
single sheet of metal with a portion for screw fastening to the face plate and
a plate
portion extending outwardly from the roof and containing the hole at a
position spaced
outwardly sufficiently to clear the eavestrough,
Where shingles are already applied, the mounting plate is located with
its edge underneath the shingles.
The base plate is fastened to the ground by stakes or other fasteners to
prevent side to side movement at the ground.
The receiving hole is dimensioned relative to the post to allow the post
to pass through the holes while at an angle to the plate different from 90
degrees to
allow the plate to be placed at an angle defined by the roof pitch.
The safety rails can be attached to the post by scaffolding clamps or
similar tubular clamps which hold the rails at a fixed height on the post.
