English Abstract


In a device for attaining height, it is a common practice to resort to the use
of a
step ladder.
In this invention, a ladder bracket and a set of telescoping legs are easily
installed
under the top plate of the ladder, to perform a safety feature by preventing
accidental side
tip-out.
A conventional step ladder consisting of four legs, only provides the user the
ability to achieve height without the security of a side tip-out.
By the addition of the two extendable telescoping side legs, broadens the
securing
area around the step ladder.
In this device, the ladder bracket having telescoping locking legs is
installed
under the top plate of the ladder, thus enabling the user the ability to
extend the legs in a
outwardly and downwardly position to allow for a wider securing circumference
around
the ladder.
By adding the optional ladder platform {T} allows a wider range of work area.


Claims

Note: Claims are shown in the official language in which they were submitted.


Claims:
The embodiments of the invention in which an exclusive property and privilege
is
claimed and sought are defined as follows.
A) In a case of a apparatus -
1.) An easily installed device for providing and securing a wider work area
around a step ladder to prevent accidental side tip-out, comprising of a
ladder
bracket, two extendable telescoping legs with locking knobs.
2.) Optional side platform consisting of a four way coupling to allow for the
additional extendable telescoping legs and platform.
3.) A device as defined in claim 1,) in which the apparatus is a (U) shaped
ladder
bracket as shown in Drawing "A" (Fig.1.a.) having screw holes to allow for
the fastening to the underside of the ladder top
b.) Ladder bracket as defined and claimed in claim 1,) also having two tubular
chambers to allow for the acceptance of the two extendable telescoping legs
and
locking knobs.
c.) Extendable telescoping legs as claimed in claim 1.), shown in Drawings A
and B (Fig.1.b.) which consist of tubular sections of pipe, with one being
placed
inside the other to allow for a telescoping action between the two.
d.) Locking knobs as claimed in claim 1.), shown in Drawings A and B(Fig.1.c.)
to allow for the securing and fastening of the two extendable telescoping
legs.
e.) Four-way connector as defined and claimed in claim 2.) shown in Drawings
A and D, (Fig.1.d.), represents an auxiliary separate connector that when
installed
to one side of the step ladder safety legs allows for the installation of up
to five
more telescoping legs which can be used to support the working platform.
4.) Optional side platform as defined and claimed in claim 2.),shown in
Drawing
D, having a four way coupling connector with additional locking knobs, which
allows for the additional horizontal extensions to support the auxiliary
working
platform to allow for a wider work area.

CA 02611716 2007-12-10
Specifications:
This invention relates to a safety accessory bracket with extendable
telescoping
legs for securing a wider circumference of area around a step ladder to allow
more
stability and help in the prevention of side tip-out.
It is common in step ladder usage, that being and consisting of, four
outreaching
legs to provide a user an elevating tool to attain vertical height.
Although efficient, ladders of this type only provide security in a forward or
backward slip-out situation at best.
By resorting to this invention one would increase the safety factor by adding
up to
seven additional supporting legs giving the user a wider circumference around
a work
area.
Description
The ladder safety bracket and legs consists of four major components, the
ladder
bracket, two extendable- telescoping safety legs, the optional four way
connector with
work platform, and the locking knobs.
The ladder bracket consists of a U shaped bracket having three holes to allow
for
fastening below the ladder top plate, as well as the two chambers for
receiving the
telescoping extendable-retractable safety legs, which can be removed when not
in use as
shown Drawing "A" (Fig. l.b.).
Extendable-retractable safety legs consisting of tubular sections, with one
placed
inside the other making for a telescoping action, whether it be, for a inward
or outward,
or for an up or downward motion for locking and securing.
Locking knobs consisting of threaded knobs with handles for securing and or
fastening the telescoping safety legs into place once established as shown in
Drawing
A
Ladder bracket as shown in Drawing "A" and represented by (Fig.l.a.) is
fastened
to the underside of the ladder top plate by either lower or upper fasteners.
Telescoping extendable-retractable safety legs as shown in Drawing "A" and
represented by (Fig.l .b.) having a telescoping action for leveling and
supporting.
Locking knobs as shown in Drawing "A" and represented by (Fig.l.c.) for the
locking and securing of the telescoping - legs.
Drawing "D" represents the optional side platform which is viewed from a side
angle which allows for the addition of five more supporting legs, which allow
for an
additional horizontal working platform giving the user a wider range of
working area.
