The field of the invention relates to devices used to secure an object onto a support structure, and more particularly to systems and methods for mounting a frame on a wall or other surface for displaying functional or decorative items.
It is common for people to hang functional or decorative items as for example pictures, artwork, documents, mirrors and other insert items on walls. Conventional hanging systems include frames that generally mount at an angle from the wall using various mounting approaches including wires and nails, picture hooks, screws and wall anchors, etc., to hang the item from the wall. These mounting approaches leave a gap between the frame and the wall and do not balance the frame relative to the center of gravity of the frame and its contents. Consequently, wall hangings especially framed pictures tend to tilt and shift relative to their desired position when hung from the wall.
It is also common for people to either replace an artwork from a wall hanging or change the ornamental frame and keep the artwork. In these situations, the frames need to be disassembled, reassembled and many times it is desired to position the newly framed artwork at the same location on the wall. In certain situations it is also desirable to mount multiple frames in a patterned arrangement on the wall. In these situations, having the ability to mount frames at precise angles and distances becomes essential in maintaining the pattern.
One problem with the commonly used frames is the high cost associated with time required for disassembling and reassembling the frames to replace the artwork or the frame itself. Another common problem is that used frame assemblies, once removed from the wall, are difficult to accurately level and precisely reposition without having to make new holes in the wall.
None of the prior art frame assemblies sufficiently address the above problems. For example, U.S. Pat. No. 6,354,031 to Meur describes a two piece frame assembly where a back panel is mounted on the wall and a frame surrounds the panel. The picture is placed between the frame and the back element. However in Meur, a space is left between the wall and the frame and the configuration of the panel does not allow for accurate leveling and placement of the frame. Another example includes U.S. Pat. No. 6,035,571 to Hsu, which describes a three piece frame assembly for displaying a picture. In Hsu, a back plate has a recess and a plurality of holes, and is connected to an ornamental intermediate plate with adhesive. The picture is placed between an additional face plate and the intermediate plate. Here, the back plate is not configured to flush mount against the wall or to provide for accurate leveling and placement of the frame. Even further, it would be time consuming to disassemble the intermediate plate from the back plate in order to allow for interchangeability of either plate.
Thus, there is still a need for a frame assembly capable to receive an item, adapted to securely and precisely flush mount against a support and having a decorative component that is easily interchanged without having to change the configuration of the frame assembly.
A frame assembly for displaying a decorative or functional insert is provided. The frame assembly includes a base frame and an outer frame. The base frame has a central mounting aperture drilled through the center of the base frame and at least one off-center mounting aperture drilled through the base frame at a point away from the central mounting aperture. A center fastener is inserted through the central mounting aperture, such that the base frame is permitted to rotate about the center fastener. Once the base frame is rotated to the desired orientation, preferably by using a level indicator, the off-center fasteners can be inserted through the off-center mounting apertures and into the support to prevent further rotation and maintain the desired orientation.
The outer frame has a display aperture to permit the viewing of the insert. A rabbet is formed on the back of the outer frame, cut around the perimeter of the display aperture. The rabbet is sufficiently sized to receive at least a portion of the base frame. Once the base frame is fastened to the support, the outer frame is mounted on the base frame, with the base frame fitting within the rabbet.

The details of the base frame (14) can be more clearly viewed in
The base frame (14) can be a solid sheet of material, however, it is shown herein as a rectangular frame with a vertical and a horizontal cross member (15), leaving four square spaces, which can be used as viewing ports during the hanging process. At the intersection of the vertical and horizontal cross members (15) a central mounting aperture (28) is drilled through the base frame (14). The location of the central mounting aperture (28) is at the center of the base frame (14), at the midpoint on the axis of symmetry, where the base frame (14) can be rotated in ninety degree increments without substantially changing the location of the central portion of the display insert. The central mounting aperture (28) may be countersunk, so that the head of the central fastener (32) is located beneath the surface of the base frame (14). Further, four off-center mounting apertures (30) are drilled away from and about the central mounting aperture (28). In this example embodiment, each of the four off-center mounting apertures (30) are located an equal distance from the central mounting aperture (28). Once the support (16) wall has been drilled with the five mounting holes, the present off-center mounting aperture (30) arrangement permits the user to rotate the base frame (14) in ninety degree increments, without drilling new holes in the support (16) wall.
To aid in leveling or positioning the base frame (14) at a desired angle, angle or gradient marks (31) may be printed about the outer perimeter of the base frame (14). These gradient marks (31) permit the use of traditional plumb-bob devices, where a bob is attached to a string. The plumb-bob may be hung from the central mounting aperture (28) or other portion of the center line, with the string indicating a vertical plum-line. The desired angle is achieved by rotating the base frame (14) until the string aligns with the gradient mark (31) corresponding with the desired hang angle. It is preferred that the gradient marks (31) be printed about two adjacent sides of the base frame (14), so that the base frame (14) may be levelly hung in a landscape or portrait orientation. Level indicators (21), such as bubble levels, may be provided to aid in level hanging. Two level indicators (21) are shown imbedded in two adjacent sides, at perpendicular orientations with respect to one another, so that the base frame (14) may be levelly hung in a landscape or portrait orientation.

Multiple base frames (14) may be easily hung in alignment by simply aligning the positions of the central mounting apertures (28) for each of the base frames (14). For example, if three base frames (14) were to be hung in horizontal alignment, equally spaced from one another, the user could simply mark a horizontal line across the wall, mark three center positions along the line with the two spaces between being equal. The center positions mark the position of the central mounting aperture (28) for each of the three base frames (14). Once the base frames (14) are mounted to the support (16), each can be rotated to the level position and fastened into place. In this way, the three pictures may appear to be in perfect alignment.
In a preferred embodiment the insert (18) is a decorative item, such as a painting, a picture, a drawing, a photograph, a lithograph, a printed image on canvas, and any other suitable art pieces. In other embodiments, the insert (18) is a functional item, such as a mirror, a blackboard, a whiteboard, a clock, a digital screen or any other suitable functional items. Yet in other embodiments, the insert (18) can be a combination of at least one decorative item and at least one functional item.
In a preferred embodiment the support (16) is a vertical wall or a ceiling wall having a flat surface (20). In other embodiments the support can be an upright support used for displaying an item, such as an easel.
The present frame assembly (10) permits the user to freely change outer frames (12) or the decorative insert (18). For example, a new decorative outer frame (12) can replace an old outer frame (12). A new art work insert (18) may replace a mirror insert (18) or an old art work insert. The present frame assembly (10) not only provides an easy method for accurately and levelly hanging a frame, it also permits the user to easily change the appearance and decorative nature of the outer frame (12) and insert (18) without undue trouble. The general hanging position and orientation of the frame assembly (10) is easily found by simply marking the desired center position on the support (16), then hanging the base frame (14) by the central fastener (32), and then rotating the base frame (14) into the level position.
