## Background
RELATED APPLICATIONS
The present invention was first described in and claims the benefit of U.S. Provisional Application No. 61/194,518 filed Sep. 29, 2008, the entire disclosures of which are incorporated herein by reference.


FIELD OF THE INVENTION
The present invention relates generally to methods for leveling picture frames and other similar wall-hung items, and in particular, to a device consisting of double sided tape with an integral ink marking means for indicating the correct placement of nails in a wall in order to ensure the even hanging of a picture frame or other similar item.
BACKGROUND OF THE INVENTION
Wall hangings such as framed paintings and pictures are one of the most common types of home decorations. One (1) of the most important aesthetic aspects of such decorations is that they are hung in a level manner, with the straight edges being parallel or perpendicular to the ground. Correctly placing wall hanging hardware such as nails or hooks in order to achieve a perfectly level decoration is a very difficult task. In addition, the removal and replacement of such hanging hardware in order to readjust a decoration can result in multiple holes in the wall and permanent damage to the house. While some people may use ink or pencil markings to indicate the proper location for hanging hardware placement, the proper placement of such markings is also difficult to achieve.
Various attempts have been made to provide a means for the quick and accurate placement of ink markings and the like. Examples of these attempts can be seen by reference to several U.S. Pat. No. 3,393,963, issued in the name of Nadai, describes a liquid dispensing applicator. The Nadai device is designed to allow for the dispensation of ink or other similar liquid when the user applies pressure to the device by hand.
U.S. Pat. No. 7,107,980, issued in the name of Craig, describes a carpenter's marking device. The Craig device utilizes a laser system to allow the user to mark a spot on a wall that is vertically aligned with a selected spot.
While these devices fulfill their respective, particular objectives, each of these references suffer from one or more of the aforementioned disadvantages. Many such devices do not provide for simple, repeatable marking capabilities in a manner that is quick and simple. Also, many such devices which do provide for simple, repeatable marking capabilities do not provide an integral means by which to level the marks. Accordingly, there exists a need for a wall marking device with integral leveling capabilities without the disadvantages as described above. The development of the present invention substantially departs from the conventional solutions and in doing so fulfills this need.
SUMMARY OF THE INVENTION
In view of the foregoing references, the inventor recognized the aforementioned inherent problems and observed that there is a need for a means of marking a wall for the correct placement of hanging hardware in a manner which allows for accurate and level hanging of an object and in a manner which is simple, easy, and quick. Thus, the object of the present invention is to solve the aforementioned disadvantages and provide for this need.
To achieve the above objectives, it is an object of the present invention to provide a wall marking device which provides a means for accurately marking a wall surface for anticipated hanging hardware such as wall anchors, eyelets, hooks, screws, etc. The device comprises a laminated assembly including a release liner, a first adhesive layer, a substrate, a second adhesive layer, and a marking bubble.
Another object of the present invention is to provide a release liner, which comprises an easily releasable sheet preferably made of plastic film, waxed-paper, etc. The release liner is intended to allow the adhesively coupled first adhesive layer portion to remain affixed to the substrate when separated.
Yet still another object of the present invention is to provide a length of substrate preferably introduced in a roll form made of flexible material, where the substrate comprises a plurality of equidistant parallel linear perforated liens approximately one (1) inch apart. It is envisioned that the substrate will comprise a closed-cell foam or similar flexible compliant material, being approximately one-sixteenth ( 1/16) to one-eighth (1⁄8) inch thick.
Yet still another object of the present invention is to provide a first adhesive layer and a release liner, comprising an adhesive attachment means to the suspended object. The first adhesive layer and release liner are located along the entire length of an underside surface of the substrate.
Yet still another object of the present invention is to provide equally spaced perforated lines, where the perforated lines perforate through both the substrate and the release liner. The perforated lines enable the device to be easily separated into individual marking segments.
Yet still another object of the present invention is to provide each marking segment with a marking bubble, which is permanently attached to a top surface of the substrate. The marking bubble is adhesively attached to the center of the segment by means of a second adhesive layer applied between the marking bubble and the substrate.
Yet still another object of the present invention is to provide marking bubbles, which comprise pliable sealed plastic enclosures that form a protruding hemispherical shape that contains a very small volume of marking ink. It is envisioned that the marking ink will comprise a generic non-permanent ink or dye such as a vegetable dye or an equivalent marking composition.
Yet still another object of the present invention is to comprise the marking bubble of a pliable sealed plastic enclosure that is designed to rupture when subject to a small amount of compressive force. It is envisioned that force applied between the suspended object and the wall surface will release the internal marking ink upon the wall surface.
Yet still another object of the present invention is to be introduced in rolls or strips that allow for a variety of convenient lengths and widths being suitable to various applications and adaptable for use with a corresponding dispensing unit similar to a common tape dispenser. It is also envisioned that the device may be introduced with identifying markings printed upon it, such as graduation markings, advertising indicia, etc.
Yet still another object of the present invention is to provide a method of utilizing the device that provides a unique means of marking a wall for the correct placement of hanging hardware in a manner which allows for accurate and level hanging of an object and in a manner which is simple, easy, and quick.
