The present invention relates to carpet tack strip removal tools. The present invention provides a carpet tack strip removal tool having a lifting arm, a pry bar arm, and fulcrum lever for operation by a user in a standing position.
Removing tack strip strips from flooring can be labor intensive and requires the use of specific tools, such as a conventional pry bar and a hammer. Unfortunately, the use of these tools requires a person removing the tack strip to spend an extending period of time on his or her hands and knees, prying the tack strip away from the flooring. This can lead to back strain and unforeseen injuries or wasted time spent taking breaks while removing tack strips. Therefore, there exists a need for a tool that provides better ergonomics by allowing a user to stand while removing tacks and tack strips, thereby preventing undue strain to the user's body.
The present invention relates to a carpet tack strip removal tool and more particularly pertains to a new system for removing carpet tack strips that allows the user to perform the task while standing.
The present invention provides a carpet tack strip removal tool that includes a fulcrum lever that is configured for activating the removal tool when a lifting force is applied to the lifting arm, and/or alternatively when the user presses down on the fulcrum lever with the user's foot. Additionally, pressing on the fulcrum lever activates the pry bar member and removes carpet tack strips. This invention conserves the health of the user while allowing for efficient carpet tack strip removal.
In light of the devices disclosed in the known art, it is submitted that the present invention substantially diverges in design elements and methods from the known art and consequently it is clear that there is a need in the art for an improvement for a carpet tack strip removal tool.

In the shown embodiment, the head 1500 includes a pry bar arm 1600 at a first side 1510 and a fulcrum lever 1700 at a second side 1520 of the head 1500. The pry bar arm 1600 is adapted to selectively engage the tack strip and through a lifting action cause the tack strip to be removed from a floor surface. The pry bar arm 1600 and the fulcrum lever 1700 are disposed on opposing sides of the shaft 1100 and wherein the pry bar arm 1600 and the fulcrum lever 1700 are aligned along a same vertical plane with the shaft 1100. In this way, the pry bar arm 1600, the fulcrum lever 1700, and shaft 1100 are symmetrical about that vertical plane. The fulcrum lever 1700 forms a tubular member that extends away from the shaft 1100. In one embodiment, the fulcrum lever 1700 is curved towards the first end 1200. A lower side of the head 1500 may be position upright on a floor surface and remain erect in a stable position.
The lifting arm 1400 extends from the shaft 1100 and provides an area for handling by the user. The lifting arm 1400 may be integral with the shaft. In an alternative embodiment, the lifting arm 1400 is removable from the shaft. In another embodiment, the lifting arm 1400 includes a curvature that is different from the shape of the curvature of the shaft 1100. The lifting arm 1400 may include a curve that aligns generally horizontally, so as to be generally parallel with the floor surface in the upright position. In this way, the curvature and position of the lifting arm 1400 allows for pressing downward (towards the floor surface) to cause the head to rotate and cooperatively encourage the pry bar arm 1600 to raise from the floor surface and the fulcrum lever 1700 to rock across the floor surface.
The shaft 1100 is shown extending from the head 1500 at an angle, i.e. not vertical. In one embodiment, the pry bar member 1600 and the shaft 1100 form an obtuse angle therebetween and the fulcrum lever 1700 and the shaft 1100 form an acute angle therebetween.

In the shown embodiments, as the carpet tack strip removal tool 1000 transitions from the setup position to the lifting position, a fulcrum point remains entirely on the fulcrum lever 1700. The “fulcrum point” is considered a point where a lever turns; in particular, the pivot point. By having the fulcrum point remain entirely on the fulcrum lever 1700, the shaft may remain relatively upright throughout the transition between the setup and lifting positions. Additionally, the construction of the shaft 1100 may be simpler and require less intricate construction. For example, other known crowbar type devices may utilize a shaft having a swan neck to function as the fulcrum point. However, having the fulcrum point lie on the shaft requires contact with the floor surface directly. This is disadvantageous as the fulcrum point is not stable during usage.
In the shown embodiment, a proximal end 1710 of the fulcrum lever 1700 extends from a distalmost end 1310 of the second end 1300 of the shaft 1100 and the fulcrum lever 1700 curves toward the shaft 1100. The pry bar arm 1600 and the fulcrum lever 1700 form a continuous lower side 1800. The continuous lower side 1800 provides stability to the user when the carpet tack strip removal tool 1000 transitions between the setup and lifting positions.
In one embodiment, the carpet tack strip removal tool 1000 comprises the shaft 1100, the fulcrum lever 1700, and the pry bar arm 1600 which are formed by a rigid monolithic member. In this way, the carpet tack strip removal tool 1000 allows for mechanical advantage during the application of the lifting force to the lifting arm.
In the shown embodiment, the angle position of the shaft 1100 relative to the floor surface controls the position of the fulcrum point on the fulcrum lever 1700, which in turn controls the lifting direction of the pry bar arm 1600 and maximum lifting height 1900. The angle position of the shaft 1100 relative to the floor surface is best measured from a side view, such as shown in
In some embodiments, the fulcrum lever 1700 of the carpet tack strip removal tool 1000 includes a degree of curvature which causes the lifting force exerted on the lifting arm to increase progressively as the maximum lifting height 1900 increases. In other embodiments, the degree of curvature causes the lifting force exerted on the lifting arm to decrease progressively as the maximum lifting height 1900 decreases or remain constant throughout the transition. In some embodiments, the fulcrum lever 1700 of the carpet tack strip removal tool 1000 includes a length provides for additional mechanical advantage and a larger relative maximum lifting height 1900.
In some embodiments, the pry bar arm 1600 of the carpet tack strip removal tool 1000 includes a length provides for additional mechanical advantage and a larger relative maximum lifting height 1900.
In the shown embodiment, the pry bar arm 1600 comprises a V-shaped notch 1650 at a tip thereof. The V-shaped notch 1650 adapted to fit between tack strips to be lifted from the floor surface and receive a nail or other fastener that secures the tack strip to the floor surface. As shown, the V-shaped notch 1650 is facing distally and is positioned at a middle of the pry bar arm 1600. Additionally, the pry bar arm 1600 is wedge shaped such that it tapers in thickness to a distalmost end thereof, wherein the pry bar arm 1600 is adapted to be positioned under the tack strip to be lifted from the floor surface.
