TECHNICAL FIELD OF INVENTION
15 The present invention relates to a railing and support device for use in
the construction of
residential and commercial buildings, and more particularly relates to a
railing and support
device to substantially protect a person from a fall during the construction
or repair of a
residential or commercial building.
BACKGROUND OF INVENTION
20 Working safely in the construction industry has become increasingly
important. Increased
fatality rates and injuries from workers falling from heights from a wall,
roof, floor or slab of a
building during construction or repair has resulted in both government and the
private sector
communities working together to reduce the risk of injury or fatality during
such construction.
25 For example, fall prevention may be used to reduce the risk of injury or
fatality during
construction. Current fall protection systems in use instruction include, for
example. Fall arrest
devices, safety harnesses, various harnesses, lanyards and shock absorbers,
scaffolding systems
erected from the ground, and railing systems, have shortcomings, for example,
scaffolding
systems erected from the ground restrict access to work below the scaffolding,
and are labour-
30 intensive to install, particularly on un even terrain.

fatality associated
with falling form a height during the construction or repair of a residential
or commercial
35 building.
It is desirable to provide devices the components of which may be used
interchangeably to
reduce the cost of ownership, maintenance and handling.

Rail Intermediate
135 Stanchion Post has been shortened with only two guard rail pockets with
a round dowel
connected to the bottom of the Stanchion Post allowing the Two Rail
Intermediate Stanchion
Post dowel to drop into a pre-existing round slot of a platform toe board
providing a guard rail
along the span of the platform when placed on with reference to patent number
2,209,805
Figure 1A, 6A, as well as the Top Plate Parapet Bracket which prevents a
person from a fall
140 when carrying out work off of the engineered platform when the span
exceeds ten feet
between brackets.

Post Extension with a single guard rail pocket with a square dowel connected
to the bottom of
145 the Stanchion Post allowing the Stanchion Post Extension to drop into
the top of Figure 2
connecting it in place with Figure 9A providing an additional guard rail
support when the lower
guard rail pocket Figure 2 (12) of Figure 2 is below the edge of a pitched
roof providing three
guard rails above the surface of the pitched roof which prevents a person from
a fall when
carrying out work on a pitched roof of a residential of commercial building.

for the purpose
of connecting the Stanchion Post Figure 2 to Figure 3A (24), the Stanchion
pocket Figure 3A (24)
length is extended and connected to an arm which has holes to receive screws
to fasten the
stanchion pocket to the outside edge of a concrete slab to provide a guard
rail around the
CA 02903893 2015-09-09
165 perimeter of the slab to prevent a person from a fall when carrying out
work on a residential or
commercial building.
Gin Wheel Pulley Connector
With reference to patent number 2,209,805 Figure 2 (10), Figure 7A, Figure 7A
(24) Figure 7C.
The Gin Wheel Pulley Connector is a square tube Figure 2 (10) a dowel

170 with a hole to receive a Gin Wheel Pulley attaching to Figure 7A (24).
This provides a worker to
safely raise and lower a working platform to the platform brackets for the
purpose installation
and dismantling process as well as tools and material used in the construction
of a residential or
commercial building.
Interior U-Bolt Brackets
175 With reference to patent number 2,209,805 Figure 6A, Figure 7C (30) The
Interior U-Bolt
Brackets consist of two right angle plates with holes fastened to the sides of
the wooden stud
with nuts and bolts a left and right side replacing Figure 7C (30) when
fastening Figure 6A to the
interior of a wood framed wall to the wooden stud. Preventing a person from a
fall over an
opening in a floor such as a stair well or when in addition to a platform a
guard rail is required
180 above ten feet of the safe surface (floor) on the interior of a wall in
residential or commercial
construction.
