ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to a friction-mountable hanger, and more particularly to hangers having a hook for hanging an object and a cantilevered part for frictionally mounting the hook. The invention contemplates the use of a single arm friction mounting element for slidable friction anchoring between face-to-face structural surfaces, and a dual arm U-shaped friction mounting element for slidable friction anchoring over opposite faces of a plate member.
People and businesses have become increasingly dedicated and competitive in decorating their homes and buildings at various times of the year, especially during holiday seasons such as at yuletide. Whether as home decoration or as business promotional decoration, the desire always is to minimize or totally avoid damage to building features or structures while nevertheless effectively implementing whatever decoration is wanted. Insofar as is known, there never has been an effective way to decorate without causing some damage to the base structures. The most common damage is that of small holes caused by nails or prongs or something else pressed into material of the base structure. What people want and have long wanted, however, is a simple way to accomplish decoration without causing damage to base structures. They want to avoid even the smallest of holes or marks or scratches of surfaces or features, whether inside or outside of a building. It is to a solution to this desire that this invention is directed.
SUMMARY OF THE INVENTION
The invention provides a plastic hanger best described by referring to its extrusion profile. The hanger has an extrusion profile that defines a stiff hook for hanging an object and a mounting element that literally relies upon friction to maintain the hanger in position. No prongs, nails, screws, adhesives, or other fasteners are needed. Mere friction gripping does the job. No puncturing of any structure is necessary.
The preferred form of mounting element comprises a stiff cantilevered element. Its extrusion profile may have a single arm or a pair of arms. The arms are formed of stiff plastic and are equipped with resiliently deformable, transversely extending fins that project angularly outward from the arm and backward toward the hook of the hanger. The fins on the single arm mounting element project from each face of it and are designed to frictionally engage opposing face-to-face structural surfaces when the mounting arm is inserted therebetween. Fins on the dual arm U-shaped mounting element project from the internal face surfaces of the two arms and function to engage or anchor the element on opposite faces of a thin structural strip or member such as a plate member. The mounting arms of the U shape are slidably pushed on opposite sides (faces) of the plate member.
Despite the amazing simplicity of the invention, the hangers are totally effective for a multitude of decorative purposes and nevertheless can be easily de-mounted (i.e., removed from mounted condition) without causing damage to base building structures.
The several benefits and advantages and desirable features of the invention will become more evident as this description proceeds.
