Description

CLAIM FOR FOREIGN PRIORITY

The present invention claims the foreign priority of a Chinese application, number 201020540198.X, having priority date of Sep. 25, 2010.

FIELD AND BACKGROUND OF THE INVENTION

The present invention relates generally to an improved design and construction of picture frame.

Picture frames available on the market today generally have structural features that only show the “nice” looking side on the front. There is no design feature about the back side of a picture frame.

Mostly commonly found picture frames today come with a simple back panel assembly mechanism, where a big gaping square hole (after putting in the intended art piece) is filled in by a panel piece, and some number of fold-in (metal) tabs are then pushed in (folded in) to keep the panel and art work in place.

The result of such crude back side picture frame is that there is some inherent danger to human handling, due to the uneven surface of the back panel assembly and the existence of the fold-in tabs.

Also, the back side does not have a nice and smooth surface feature and is unappealing. Wall surfaces tend to have more scratches and scrapes by the use of these traditional type of picture frame with the back side described above.

Present invention provides for a new type of back panel assembly mechanism that is both visually appealing and smooth and easy to handle.

OBJECTS AND SUMMARY OF THE INVENTION

Present invention provides picture frame structure, where the intended art piece is held in place by a foam padding, covered with a back panel that is flush with the outside raised ring of the back side of the picture frame, resulting in a visually appealing back side of a picture frame that is safe to handle and less likely to scratch and scrape wall surfaces.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The picture frame 1 of present invention is made up of four (4) frame strips 4, joined together at 90-degree angle with respect to any of two neighboring frame strips, and forming the main frame shape.

A back panel 3 and a form padding 5 work together to wedge the intended art piece 2 in place, when the back panel 3 is affixed to the back side of said picture frame 1.

Reference FIG. 1.

On each of the frame strip 4, an inside step 41 is formed and an outside raised step 42 is formed, as shown in FIGS. 5 & 6. As such, when four frame strips 4 are joined together (90-degree between any two frame strips 4), a rectangular raised ring 10 is formed by the raised steps 42 on the outside edge of the frame strip 4.

The rectangular concave area formed by joining the inside step 41, see FIG. 4 and FIG. 6, is for placing the art piece 2 into the picture frame 1.

Foam padding 5 will be sized to fit the same rectangular concave area formed by the multiple inside steps 41, when four frame strips 4 are joined. A back panel 3 is then placed over said foam padding 5, and forming a flush fit within the area defined by the rectangular raised ring 10.

Note that in actual implementation, the height of the inside step 41 can have several pre-set figures, such as 0.3, 0.4, 0.5 up to 1 cm, with corresponding foam padding having varying thickness of 1 cm, 0.9, 0.8 down to 0.3 cm, so that the art piece 2 can run as thin a single sheet of paper, or with added thickness with the addition of mattings of various thickness, resulting in the placement of foam padding 5 on to the art piece 2 to form a generally flat rectangular surface inside the rectangular raised ring 10, for receiving the back panel 3.

Note also that the art piece 2 envisioned herein can further have a transparent layer on the outside (user-viewing side) made up of materials such as glass, think plastic film, plexiglass, or other transparent protective layer. The combined thickness, with the added transparent layer, should be taken into consideration for purpose of adding on the different foam padding 5 thickness, and to have an ultimate generally flat surface after the back pane 31 is put in.

Note also that the nature of foam padding 5 is that it will be puffed up a little in the flat concave area surrounded by the raised steps 41, due to the inherent cushiness feature of foam material. As such, when placing the back panel 3 on to the foam padding 5, the art piece 2 and the foam padding 5 will have a nice snuggly fit into the picture frame 1.

When joining the four frame strip 4, flat staples 51 can be used to quickly connect two adjoining strips 4 together. Alternatively, common wood glue can also be used to join all four frame strips.

When placing the back panel 3 on the back side of picture frame 1, similar type of flat staples 52 can be used to quickly set the back panel 3 in place, against the back side of foam padding 5, and presenting a nice and flush back surface of the picture frame 1, as taught by present application.

Two holes 32 are formed on back panel 3, having a string 9 going through the holes, for purpose of hanging assembled picture frame 1. Due to the cushy nature of foam padding 5, knots 90 will be pressed against the surface of foam padding 5 when the back panel 3 is placed upon it and form a nice and flush assembled back side of a picture frame, with a string 9 ready for hanging.

The thickness of back panel 3 will be substantially the same height as that of raised step 42 (forming the raised ring 10 when the 4 sides are joined).

Consequently, the back side of a fully assembled pictured pursuant to the teaching of present application will be nice and smooth and visually pleasing.

Claims

1. A picture frame, comprising: A plurality of frame strips wherein each of said frame strip has an inside step on the inner side and a raised step on the outer side, and when four of said frame strips are joined to form a rectangular shape, an outer rectangular raised ring is formed, for receiving a back panel snugly fit to the inner edge of said rectangular raised ring.

2. The picture frame of claim 1, wherein said back panel is roughly the same thickness as the height of the raised step, so that when back panel is assembled to the joined frame strips, the back panel surface is generally flush with the surface of the rectangular raise ring.

3. The picture frame of claim 2, wherein a foam padding is provided to fit into the concave area formed by the inside steps when the four frame strips are joined in a rectangular shape, so that an art piece will be pressed snugly in place by said foam padding, when said back panel to assembled to the back side of said picture frame.

4. The picture frame of claim 3, wherein the foam padding can have varying thickness, corresponding to the height of the inside step, to accommodate varying thickness of the art piece to be place into the picture frame for display.

5. The picture frame of claim 3, wherein the back panel contains two holes, allowing a string to be tied through the two holes, for hanging up an assembled picture frame.
