Powered tile breaker

Abstract

A powered tile breaker has 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. 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.

Claims

1. A powered tile breaker having an adjustable frame and said frame further comprised of a handlebar member, a foldable shaft, a base member, and wheels; said base member holding a chiseling assembly; said chiseling assembly comprising a main electric motor located inside a motor casing, said motor powering a chisel member; said chiseling assembly angularly adjustable by way of an actuator member which consists in a secondary electric motor driving a piston; said piston having one end rotationally connected to the base member, and said actuator member is rotationally connected to a lever member which extends from said chiseling assembly and which connects at a pivot point; a knee push member acting as a low center of gravity secondary pushing point for pushing said tile breaker forward.

2. The powered tile breaker of claim 1 wherein said chiseling assembly being adjustable to angles adjustable between 0 and 60 degrees in a fluid and continuous range while said tile breaker is in operating mode.

3. The powered tile breaker of claim 1 wherein said angle adjustment [being electrically controlled by way of a switch.

4. The powered tile breaker of claim 1 wherein a set of indicia, and an indicia pointer, located on the side of said motor casing serve as reference for indicating an angle of rotation of said motor casing as it pivots around said pivot point.

5. The powered tile breaker of claim 1 wherein said breaker also includes a stopper member for stopping said angularly adjustable chisel assembly.

6. The powered tile breaker of claim 1 wherein said shaft having a hinge and a means for locking so that it can be folded.

7. The powered tile breaker of claim 1 wherein said chiseling assembly having a Y shaped extension member to plow away broken tiles aside.

8. The powered tile breaker of claim 1 wherein said shaft is adjustable angularly in combination with the angular adjustment of said chiselling assembly.

DETAILED DESCRIPTION

(7) 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.

(8) 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).

(9) 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, 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).

(10) 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.

(11) 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.

(12) 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).

(13) There is, of course, a main on/off switch (44) on the handlebar member (14) to turn the tile breaker (10) on or off.

(14) 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.

(15) 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).

(16) 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.

(17) 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.
