DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] The following description of the preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.

[0022] Generally, the present invention is a trim removal device with a flat head of such rigidity and width, so as to allow the application of a torsional force, created by a twisting action of a t-handle, transmitted through a shaft of sufficient length, so as to allow the application of the force from a standing position, with a handle of sufficient design, such as, but not limited to a T-shaped design, so as to allow the most easily delivered method of manually applying the twisting action, by effectively transferring the torsional force provided by the user, to a head which is of sufficient width to allow effective leverage between the two sides of the blade, with each side-edge alternating its role as a fulcrum to the leveraging action of the opposite side, so as to more easily disengage a variety of trim from its mounting surface, by applying the head of the device between the void between the targeted trim, and its mounting surface, such as, but not limited to drywall, with the purpose of easing the task of trim removal, and reducing damage to the mounting surface, which is an inherent problem with traditional and current methods of trim removal. With the interchangeable heads and telescoping shaft described below, the trim removal tool can be used for base trim or molding, base coping trim, crown molding trim, chair rail molding trim or any other type of trim fixed to a wall.

[0023] The improved trim removal tool of the present invention is designed to minimize or entirely remove the shortcomings from the current methods of removing crown or base trim. The trim removal tool has a special head, designed to allow the user to apply the forces necessary to separate the trim from its mounting surface, by using a torsional force, which is created by a twisting action of the device. The trim removal tool effectively transfers the twisting action provided by the user, to a head which is of sufficient width to allow effective leverage between the two sides of the blade, with each side alternating its role as a fulcrum to the leveraging action of the opposite side. The trim removal tool has a shaft of sufficient length and a handle of sufficient length and design so as to allow the application of the twisting action from a standing position.

[0024] The handle shape can be a T-shaped design or a delta-shaped () design as shown in the FIGS. 1 and 2 or may be any other shape that has a longitudinal axis that is substantially perpendicular to the longitudinal axis of the tool's head. With the preferred bent shaft design (discussed below), the handle's longitudinal axis is perpendicular to the shaft's central plane and intersects with the longitudinal axis of the shaft's proximal section. The perpendicular relationship of the handle to the tool's longitudinal axis and the shaft's central plane provides a moment arm that allows the user to apply a torque around the head's longitudinal axis for a more efficient separation of the trim away from the wall. The handle itself may also be removable in some embodiments as shown in FIG. 7. A removable handle preferably has a pin that holds the T-shaped handle within the end of the elongated tubular shaft. When the pin is removed, the T-shaped handle can be removed from the shaft. This allows a person to easily switch the shape of the handle or remove the handle all together should a person need to get into a tight area such as tight corners. Also, having a removable handle offers a benefit when shipping the tool whereas the entire unit can fit in a smaller carton when the handle is detached.

[0025] The shaft preferably has a bend in it between the proximal section and the central section, and the central and distal sections of the shaft preferably have a common longitudinal axis that is substantially parallel to the longitudinal axis of the tool's head. The parallel longitudinal axes can be aligned with each other or can be transversely offset as shown in the drawings. The tool head is preferably connected to the front side of the shaft's distal end. This location of the tool head and the bend in the shaft allows a user to place the shaft's center and distal sections and the head flush with the wall so that the leading edge of the head is nearly aligned with the plane of the wall. Specifically, the front side of the shaft's distal section can be placed flush to the wall when the tool is initially used to create or follow the space between the wall and the trim so having the head extending from the front side of the distal section allows the head to be aligned with the wall and the space. The bend in the shaft at the proximal section provides for an offset of the handle away from the wall when the distal section is flush with the wall which provides a space between the user's hands on the tool's handle grips and the wall, thereby preventing any interference in aligning both the distal section and the tool's head with the plane of the wall. The shaft may also have telescoped sections to adjust the length for users of different height and different reaches required for trim that may be located along the floor or the ceiling, however a shaft having a fixed length is also applicable to the tool described herein.

[0026] The pry and torque tool according to the present invention has the elongated shaft, the handle, and the head. The elongated shaft extends from the proximal section through the center section to the distal section. The center section and distal section have a common longitudinal axis, and the proximal section's longitudinal axis obliquely intersects the common longitudinal axis. These shaft axes are within a central dividing plane.

[0027] The handle is connected to and extends from the proximal section of the elongated shaft as shown in FIG. 1. As indicated above, the handle's longitudinal axis is substantially perpendicular to the central plane and the head's longitudinal axis and intersects with the proximal section's longitudinal axis. The bend in the shaft results in the handle's longitudinal axis being transversely offset from the common longitudinal axis toward the backside of the elongated shaft. The center portion of the handle is preferably located within the shaft's central plane.

[0028] The head has a proximal end connected to the front side of the distal section. The head has a single prong extending longitudinally, shown in FIGS. 3, 4 and 5, and flaring laterally from its narrowest width at the proximal end to a broader width at the leading edge that extends along the head's flared distal end. The flared distal end has a lateral axis substantially parallel to the handle's longitudinal axis, and the flared distal end has a transverse location between the shaft's front side and backside inclusive. Accordingly, the single prong of the head can be completely flat, as shown in FIG. 4B, or it may have some curvature that is preferably no greater than the distal section's transverse thickness between its front side and backside, as shown in FIGS. 3B and 5B. It will be appreciated that the single prong can be straight or bend transversely away from the front side of the distal section and toward the backside, and the flared distal end may have a transverse location between the front side and the first longitudinal axis inclusive.

[0029] Since the tool is different from most elongated pry bars which are designed for demolition and are solid or have very thick wall sections, the tool of the present invention is designed to provide a rotational torque as well as a prying action to minimize damage to the wall and avoid breaking the trim. Accordingly, the tool does not need to be solid or have thick walls. Therefore, to reduce the weight of the tool and reduce fatigue on the user, the elongated shaft is preferably comprised of a thin-walled tube with a tube wall thickness that is less than one fifth of the tube diameter. Additionally, as indicated above, the tubular shaft sections can be formed as telescoping sections with a coupler between the telescoping sections. Preferably, the distal section has a smaller outer diameter than the inner diameter of the shaft's proximal and center sections which allows it to telescope into the interior of the shaft's proximal and center sections.

[0030] As shown in the FIG. 1B and 2A, the telescoping tube sections of the shaft can be locked in place using a push-button detent that is connected to an inner concentric tube section and which extends through a hole in a series of holes spaced along the outer concentric tube section. Examples of push-button detent couplings are also disclosed in U.S. Pat. No. 3,347,575 and U.S. Des. Pat. No. 482,752 which are incorporated by reference herein. An alternative coupling between the telescopic tube sections of the shaft could be compression coupling as particularly described in U.S. Pat. No. 5,649,780 which is incorporated by reference herein. Alternative types of adjustable-length poles with concentric tubular sections are described in U.S. Pat. No. 6,027,087 and US Pat. Pub. No. 2010/0310306 which are hereby incorporated by reference herein. Another type of compression coupling and examples of its components are particularly described in U.S. Pat. No. 3,545,794 which is incorporated by reference herein.

[0031] The present invention also allows for interchangeable heads that may take multiple embodiments as depicted in FIGS. 3, 4 and 5. Generally, the heads have a width at the proximal end substantially equal to the transverse thickness of the distal section of the elongated shaft, and the width of the flared distal end is greater than at least twice the width of the distal section. In one embodiment shown in FIG. 3, the head's single prong may be elongated such that its longitudinal length is at least five (5) times as long as the width of the head's proximal end. In another embodiment, the head's single prong may be broadened such that it has a lateral width approximately equal to the longitudinal length. The elongated prong can have a rectangular or trapezoidal shape with a sharpened leading edge substantially parallel to the handle's longitudinal axis and may be flat or have a concave front surface. As explained below, the broadened prong is designed to work best with cove base trim, and it has a generally parallelogram-shape with a sharpened leading edge and a concave front surface, as in FIG. 5.

[0032] The head design for removing cove base trim shown in FIG. 5 preferably has a scooped, concave surface that is designed to deliver a leveraging action as the head is pulled parallel to the void between the cove base trim and its mounting surface. The head sufficiently disengages the cove base trim from the wall's drywall surface or other mounting surface with an angle of sufficient deviation so as to cause the cove base trim to easily separate from the mounting surface. The leading edge is sharpened to create a cutting edge that effectively severs the cove base trim from its mounting surface. By severing the adhesive used to mount the cove base trim to its mounting surface, the head facilitates the expedient removal of the cove base trim with a less damaging outcome to the mounting surface than current methods. Cove base trim is many times made of a rubber or vinyl composition.

[0033] In another embodiment depicted in FIG. 7, the head also has a foot tab extending from the proximate end of the head. In operation, the foot tab allows a person to use the pressure from their foot to push the head of the tool down and wedge it between the baseboard and the wallboard. The tab may vary in size but is preferably proportionate to the size of the head and may be affixed to any of the aforementioned head shapes or other head shapes. The tab extends substantially perpendicular from the backside of the head and preferably spans entire distance between the side edges of the head. The tab preferably extends from the head a distance that is approximately equal to or less than the width of the leading edge of the head. In some embodiments the tab is c-shaped, as shown in the figures, but the tab may also be any other similar shapes that allow a person to apply pressure with their foot. The tab is shown mounted to the elongated rectangular head, and it will be appreciated that this tab could also be used with a broadened head.

[0034] In another embodiment not shown, the shaft has a bend between the central section and the distal section of the shaft, and the distal section of the shaft preferably has a common longitudinal axis that is substantially parallel to the longitudinal axis of the tool's head. The location of the bend in the shaft in this area allows a user to utilize the bend as a fulcrum, to expand the option of movement offered by the present invention, to dislodge the trim from its mounting surface by using a leveraging forward/backward motion, with the mounting surface acting as a base for the fulcrum created by the bend to rest upon. This embodiment of the shaft is shown with an elongated rectangular head, and it will be appreciated that this shaft could also be used with a broadened head.

[0035] The trim removal tool provides a less destructive method for removing base or crown trim, than current devices and long-handled pry bars, (which allows for the delivery of a leveraging action, perpendicular to the user, that applies its pulling action to the top of the trim, pulling the trim away from its mounting surface at a slant) by providing a device, which delivers an alternating leveraging action, that applies its pulling action along the left and right edges of the head of the device, resulting in an evenly distributed action, that keeps the base trim parallel to its mounting surface. This improvement accomplishes its goal to remove trim, with less potential damage to the top portion of the trim, its mounting surface, and any adjacent floor, wall, or ceiling surfaces that connect to the primary mounting surface, than current methods.

[0036] The embodiments were chosen and described to best explain the principles of the invention and its practical application to persons who are skilled in the art. As various modifications could be made to the exemplary embodiments, as described above with reference to the corresponding illustrations, without departing from the scope of the invention, it is intended that all matter contained in the foregoing description and shown in the accompanying drawings shall be interpreted as illustrative rather than limiting. According to the alternative versions of the tool features described above, the trim removal tool more easily disengages a variety of crown and base trim from its mounting surface, by applying the head of the device between the void between the targeted trim, and its mounting surface. The trim removal tool is designed to ease the task of trim removal, and reduce damage to trim and the mounting surface. Thus, the breadth and scope of the present invention should not be limited by any of the above-described exemplary embodiments, but should be defined only in accordance with the following claims appended hereto and their equivalents.
