CA 02911896 2015-11-16
Powered tile breaker
FIELD OF THE INVENTION
[001] The present invention relates generally to power tools but more
particularly to a powered tile breaker.
BACKGROUND OF THE INVENTION
[002] Breaking ceramic tiles is a very hard job and special chisels have been
developed for that task. Still, doing that manually is hard and takes a
long time. Powered devices have been developed over the years such
as:
[003] US20070228805 by Due which describes a power hammer apparatus
including a cart and a power hammer arrangement mounted at a front
region of the cart. The power hammer arrangement includes a
reciprocating bit that contacts a working surface to break up the working
surface as the power hammer is advanced by the power-driven cart.
[004] US8240682 by Kennard describes a jackhammer trolley comprising a
mainframe member with a clamp member at the bottom end and an
extension bracket portion at the top end, a base frame member
removably attached to the mainframe member by pivoting joints with at
least one wheel member removably attached to its bottom, a handle
member having a hand lever attached to said top end, and at least one
1

CA 02911896 2015-11-16
vibration dampener fixed to said top or bottom end of the mainframe
member.
[005] There are several drawbacks and limitations the the prior art most
notably in the possible adjustments which are limited to a few positions,
which means that not every user can find an optimum ergonomic
position in which to work, as not all sizes are covered. The machine of
the prior art, lack some basic folding capabilities which can make the
machine more compact for easy transportation even in a passenger car.
Most importantly, the angle of the chisel is limited to specific angles that
can only be modiified prior to using the machine, not in use. Also, there
are limitations in the adjustments, more particularly the handle part
which may not be suitable for a wide range of user sizes.
SUMMARY OF THE INVENTION
[006] In view of the foregoing disadvantages inherent in the known devices
now present in the prior art, the present invention, which will be
described subsequently in greater detail, is to provide objects and
advantages which are:
[007] To provide for a powered chiseling tool that is portable, and
transportable. Various adjustments to keep the device in a most
ergonomic fashion no matter the height of the user. A means of
adjusting the angle of the chisel in a wide variety of angles, on the fly
while operating the machine. A knee push member which lowers the
center of gravity so that a user can keep his stability while giving the
2

CA 02911896 2015-11-16
maximum pushing forward thrust to the machine should a patch of
tiles be more difficult to remove.
[008] In order to do so, the invention comprises an adjustable frame and the
frame is further comprised of a handlebar member, a foldable shaft, a
base member, and wheels. The base member holds a chiseling
assembly which comprises a main electric motor located inside a
motor casing. The motor powers a chisel member.
[009] The chiseling assembly is angularly adjustable by way of an actuator
member which consists in a secondary electric motor driving a piston.
The piston has one end rotationally connected to the base member,
and the actuator member is rotationally connected to a lever member
which extends from the chiseling assembly and which connects at a
pivot point.
[0010] The chiseling assembly is adjustable to any angles in a fluid and
continuous range while the tile breaker in operating mode.
[0011] The angle adjustment mode is electrically controlled by way of a
switch.
[0012] The angles are adjustable between 0 and 60 degrees.
[0013] A set of indicia, and an indicia pointer, located on the side of the
motor
casing serve as reference for indicating the angle of rotation of the
motor casing as it pivots around the pivot point.
3

CA 02911896 2015-11-16
[0014] A stopper member for stopping the rotation of the chisel assembly.
[0015] The shaft has a hinge and lock means so that it can be folded.
[0016] The chiseling assembly has a "Y" shaped extension member to plow
away broken tiles aside.
[0017] A knee push member acts as a low center of gravity secondary
pushing point for pushing the tile breaker forward.
[0018] The shaft is adjustable angularly in combination with the angular
adjustment of the chiselling assembly.
[0019] There has thus been outlined, rather broadly, the more important
features of the invention in order that the detailed description thereof
that follows may be better understood, and in order that the present
contribution to the art may be better appreciated. There are additional
features of the invention that will be described hereinafter and which will

DETAILED DESCRIPTION
[0029] A powered tile breaker (10) has an adjustable frame (12) having a
handlebar member (14), a shaft (16), and wheels (36) to hold a
chiseling assembly (18) which is comprised of a main electric motor (not
shown), located inside a motor casing (22), and powers a chisel
member (24) located at ground level.
[0030] The chiseling assembly (18) is angularly adjustable by way of an
actuator member (26) which consists in a secondary electric motor (28)
driving a piston (30). The piston (30) has one end rotationally connected
to a base member (50), and the actuator member (26) is rotationally
connected to a lever member (54) which extends from the chiseling
assembly (18) and which connects at a pivot point (56).
[0031] This allows for the adjustment of the chiseling assembly (18) to any
angles in a fluid and continuous range of between 0 to 60 degrees.,
6

CA 02911896 2015-11-16
while the tile breaker (10) is in operation. The adjustment means is
controlled by a simple "up and down" button (32) located on the
handlebar member (14).
A set of indicia (34), and an indicia pointer (37), located on the side of
the motor casing is used as a reference to indicate the angle of rotation
of the motor casing (22) as it pivots around the pivot point (56), and a
stopper member (35) stops the rotation to prevent the chisel member
(24) from pointing backwards.
[0032] The shaft (16) has a hinge and lock means (38) so that it can be folded
in half for easy transportation in a small vehicle, for example.
[0033] The chiseling assembly (18) has a "Y" shaped extension member (42)
which acts as a plow to push broken tiles aside. It also acts as the pivot
point (56) for rotating the chiseling assembly (18).
[0034] There is, of course, a main on/off switch (44) on the handlebar member
(14) to turn the tile breaker (10) on or off.
[0035] At the rear of the tile breaker, (10) and facing a user (46), is a knee
push
member (48) which allows for the user (46) to use his knees (one knee
at a time) to further push the tile breaker (10) forward by exerting the
upper body far less and as such, reduce stress related injury.
7

CA 02911896 2015-11-16
[0036] The shaft (16) can be adjusted angularly so as to provide a maximum
level of adjustments so as to be customizable to any given user (46).
[0037] As to a further discussion of the manner of usage and operation of the
present invention, the same should be apparent from the above
description. Accordingly, no further discussion relating to the manner of
usage and operation will be provided.
[0038] With respect to the above description then, it is to be realized that
the
optimum dimensional relationships for the parts of the invention, to
include variations in size, materials, shape, form, function and manner
of operation, assembly and use, are deemed readily apparent and
obvious to one skilled in the art, and all equivalent relationships to those
illustrated in the drawings and described in the specification are
intended to be encompassed by the present invention. Therefore, the
foregoing is considered as illustrative only of the principles of the
invention. Further, since numerous modifications and changes will
readily occur to those skilled in the art, it is not desired to limit the
invention to the exact construction and operation shown and described,
and accordingly, all suitable modifications and equivalents may be
resorted to, falling within the scope of the invention.
