The frame also includes at least one fastening element (40) associated with the edge support with a snap fit for fastening the poster edge thereto. A double-sided poster frame is also disclosed.

Description: BACKGROUND OF THE INVENTION The present invention relates to a picture frame for framing pictures, posters, prints, signs and the like. More particularly, it relates to such a picture frame for the inexpensive, yet aesthetically pleasing and practical framing of a wide variety of pictures for both residential and commercial use. In my earlier patent for a picture frame, U.S. Patent No. 4,669,209, I have described a picture frame which is very inexpensive and so easy to assemble that most can do so with aesthetic and precise results. The picture frame is designed to eliminate the need for a picture glass or other transparent covering and semi-rigid backing, normally used for most picture frames. It was specifically intended for framing posters, which tend to be relatively large, and prints. Artistic decor utilizing posters and large prints has come into vogue in recent years. Where such poster-type pictures are inexpensive, it is often times not worthwhile to provide the same with a glass covering and a semi-rigid backing, together with a frame, for the entire assembly since these various extra elements often cost far in excess of the original poster to be framed. Thus, on many occasions, one sees attractive poster-like pictures which are tacked or otherwise fastened to a wall for the purpose of exhibiting the picture and maintaining it flat. Such securement of a poster-like picture to a wall not only causes damage to the wall but very often tends to be unsightly, in that tacks or tape, or other objects are utilized in fastening the picture to the wall. To overcome this problem, my earlier patent provided a picture frame for poster-like pictures which included at least a top picture edge support, and preferably a bottom picture edge support, and fastening elements which fasten the respective edges of the poster-like picture frame to the top and bottom supports. Each picture edge support includes a flat back plate which extends substantially the length of the edge of the picture being framed and a substantially C-shaped portion or member, one leg of which is connected to the outer edge of the back plate, while the other leg extends downwardly toward the flat back plate to define a gap between the terminus thereof and the back plate. The picture edge support is preferably formed of extruded plastic. The fastening elements are also generally C-shaped and resiliently engaged around the generally C-shaped member of the edge support with the inside leg extending into the gap beyond the terminus of the inside leg of the C-shaped member and the flat back plate, so as to press the edge of the poster-like picture inserted into the gap against the back plate of the edge support. The patent also contemplates the provision of edge supports for each side edge of the poster-like picture, wherein the fastening elements are in the form of elbow-shaped corner pieces, which engage the adjacent ends of adjacent edge supports so as to secure or fasten the poster-like picture to the flat back plates of the supports at the corners of the picture. While quite satisfactory in use, I have found that for certain applications a more rigid or stiffer picture frame is needed. In addition, the picture frame is not suitable for joining multiple pictures or posters together. It is also not particularly suitable for double-sided signs, such as may be often used in store windows and the like, where it is desired that the customer can read the same either on the outside of the store or on the inside thereof. OVERVIEW OF THE INVENTION Accordingly, it is an object of the present invention to provide an improved picture frame for poster-like pictures, wherein no support elements or structure are utilized with the picture other than the picture frame itself, which is of simple and inexpensive construction. It is also an object of the present invention to provide such a picture frame which affords greater rigidity in the frame structure and allows greater versatility of use in connection with the grouping of different pictures. Certain of the foregoing and related objects are attained in a frame for a poster and the like as claimed, which includes at least one edge support for an edge of the poster and at least one fastening element associated with the edge support for fastening the poster edge thereto. The edge support extends substantially the length of the poster edge and includes an inverted generally T-shaped back plate extending the length thereof, having a base leg and an upstanding leg disposed generally, normally to the base leg and having a first end interconnected, generally centrally of the base leg and a second end. The edge support also has a generally C-shaped dome member having a center section interconnected with the second end of the upstanding leg of the back plate and two curved legs, each of which extend toward opposite ends of the base leg of the base plate to define a gap between the ends of the curved legs and the base leg for the purpose of receiving the respective edge of the poster. The fastening element has first and second legs and is substantially C-shaped to overlay the C-shaped member of the edge support and engage therewith with a snap fit. The legs of the fastening element extend beyond the ends of the curved legs of the C-shaped dome member and toward the base leg of the back plate, to press the poster edge against the base leg to thereby fasten the same and to cooperate so as to wedge and secure the poster edge therebetween. BRIEF DESCRIPTION OF THE DRAWINGS Other objects and features of the present invention will become apparent from the following detailed description considered in connection with the accompanying drawings. It is to be understood, however, that the drawings are designed as an illustration only and not as a definition of the limits of the invention.

For the purpose of maintaining picture 20 flat so that it may be hung from a wall or similar structure without distortion, the upper, lower and side edges of picture 20 are provided with substantially identical edge supports, generally designated 30, to which fastening elements, generally designated 40, are engaged for securing picture 20 to the edge supports 30. The edge supports 30 are preferably made of plastic extrusions and the fastening elements 40 are preferably formed of injection molded plastic. As clearly seen in Fig. 2, each edge support 30 includes a back plate 32, having a generally inverted T-shaped profile which is composed of a substantially flat base plate 33 and an upstanding leg 34, disposed centrally and normally thereto. A substantially C-shaped dome member 35 is interconnected to the top end of leg 34 and is provided with legs 36, 37, which curve downwardly toward the lateral edges of base plate 33, to define slots or gaps 38, 39, between the terminus of legs 36, 37 and the ends of base plate 33, respectively. Gaps 38, 39 are sufficient to permit the insertion therein of the edge of the poster-like picture frame 20. As shown in Fig. 3, elbow-shaped fastening element 40 is shown as having a substantially C-shaped configuration which basically conforms to the shape of dome member 35 of edge support 30, but having an inside diameter slightly smaller than the outside diameter of member 35, so that a snap fit results when fastening element 40 is engaged with member 35 because of the increased tension therebetween. The depending legs 42, 44 of fastening element 40, are provided adjacent their ends with engagement cams or bosses 46, 48, respectively. The configuration and construction of these fastening elements are similar to that of the connecting elements used in an electric cord holder assembly described in my U.S. Patent No. 4,563,542 (the subject matter of which is incorporated herein by reference thereto). As seen best in Fig. 4, the edge of the poster 20 is inserted into the gap 39, such that the edge thereof lies against base plate 33. Then, the C-shaped fastening element 40 is pressed over the top of dome member 35, such that the bosses or engagement cams, 46, 48, extend into gaps 38, 39 in a snap fit manner, as a result of which the poster 20 is pressed against the base plate 33 and held securely between it and the bosses 48. Figs. 5-7 better illustrate the sequence of steps in forming the picture frame of the present invention. As shown in Fig. 5, the first step is to insert an edge of the poster 20 into the gap 39 of edge supports 30 along each of the edges thereof. Then, the elbow-shaped fastening elements 40 are snapped over the corners of each of the posters, as shown in Fig. 7, such that each fastening element connects two adjacent edge supports 30. This results in the poster frame, as shown in Fig. 1. This particular embodiment provides an improvement over applicant's earlier patent, U.S. Patent No. 4,669,209 (the subject matter of which is incorporated herein by reference thereto), in that the poster can be inserted into either or both sides of the edge support 30 so that a series of posters could be hung in a composite or sequential manner (as will be discussed hereinafter). In addition, this embodiment also provides improved strength, in that a wedge-like connection is formed at both sides of the edge support 30 with the fastening element 40, which improves the gripping hold of fastening element 40 and improves the rigidity of the structure. Furthermore, while the edge support is shown as having equal size gaps, they could be of different dimensions, so that one side could be used for thin paper, while the other side could be used for paperboard which has a larger thickness. The slots are preferably dimensioned to be equal to or slightly greater than the intended thickness of the poster to be hung. In addition, although the openings are shown as being a fixed open slot, they could have a flex-type opening, whereby the slot would be substantially covered but could be flexed open by the insertion of the paper or paperboard due to the resilient nature of the legs 36, 37. Fig. 8 discloses an alternate embodiment of the picture frame, wherein a scroll-type arrangement is depicted. In this case, the upper edge and lower edge of picture 20 are provided with substantially identical edge supports 30, to which fastening elements 40′ are engaged for securing picture 20 to the edge supports. As seen best in Figs. 9a and 9b, the rectilinear fastening elements 40′ which serve as end caps also have a C-shaped profile defined in part by depending legs 42′, 44′ which are also provided with bosses 46′, 48′ adjacent one end thereof. Fastening elements 40′ are also provided with a closed wall 49 at one end, so as to afford a neat, aesthetic appearance for the scroll-like frame. Although not illustrated, it is possible that the scroll could be continued by inserting paper at both sides of the edge support 40 of either the top or bottom end such that a series of scroll-like framed pictures would be joined together. Figs. 10 and 11 illustrate a fastening element 40″ having a T-shaped profile which can be used if it is desired to secure together a series of pictures. These T-shaped fastening elements 40″ are similar to the other fastening elements 40, 40′, in that they have similar camming elements or bosses 46″, 48″ adjacent each end thereof, which function in a similar manner. The use of such T-shaped fastening elements 40″ will be described in greater detail hereinafter. The poster frames of the present invention can be hung by conventional means, wires, hooks, Velcro fasteners, etc. However, to facilitate the hanging of the poster frame, one or more of the edge supports 30′ of the poster frame can be modified, as shown in Fig. 12-14. As can be seen therein, one edge of the base plate 33′ is shortened, as is the corresponding leg 36′ of the C-shaped dome member 35′, so as to provide a greater opening for the insertion of a hanger element 50. Hanger element 50 has a U-shaped base 52 which is configured and dimensioned to be frictionally and slidably receivable witnin the opening defined between the base plate 33 and the leg 36′ of the C-shaped dome member 35′ of the edge support 30′ and an eyelet section 54 having an opening 55 for the fastening of a hanging wire or nail for hanging the poster. This modified edge support 30′ could be substituted for the top edge of the poster frame, so that it may be hung by a nail or the like. Alternatively, it could be used to form the side edge supports for the picture frame in which case a wire (not shown) could be attached to the two eyelets to permit the picture frame to be hung by the wire across the back of the picture and frame. The dimension of the hanger element 50 is selected such that the mounting of the same requires the aid of a tool, pin or the like and so that it will not slide freely and will stay in its intended position, as shown in Figs. 13b and 14. This is facilitated by preferably providing a small protuberance 57 on the bottom or back of the hanger element which allows easy entry of the hanger element into the slot by a camming action. When the picture is hung, the protuberance will cause the hanger element when in its intended position to tilt upwardly slightly causing it to grip the channel surface more firmly so as to prevent unintentional sliding. While only one embodiment of the present invention has been shown and described, it is obvious that many changes and modifications may be made thereunto without departing from the scope of the invention.
