BACKGROUND

Technical Field

The present disclosure generally relates to frames and, more particularly, to picture frames.

Description of the Related Art

Conventional frame assemblies, such as frame assemblies used to display pictures or photographs, typically include a frame with a recess for positioning a picture therein. An outer cover is then affixed to the frame to secure the picture. The outer cover typically surrounds a peripheral portion of the picture and includes clips or hooks to fasten the outer cover to a rear surface of the frame. The entire frame assembly is then rigidly affixed to a hanging structure such as a wall, via nails, screws, bolts, hooks, or other fastening devices.

Conventional frame assemblies, however, may suffer from a variety of drawbacks. For example, to replace the existing picture may require removing the entire frame assembly from the hanging structure and

disassembling the frame assembly to remove and replace the existing picture. Further, hanging pictures using such frame assemblies may require several iterations before a precise and level frame assembly is affixed to the wall, which may leave several undesirable marks on the hanging structure. This problem is further exacerbated when assembling an array of pictures. Each frame assembly would have to be level and precisely positioned relative to adjacent frame assemblies, thus requiring complex and labor intensive level and plumb indicators. Still further, to properly align the picture within the recess may require the frames to be manufactured with tight tolerances; failure of which may result in the picture being positioned in a skewed or slanted manner. The frame assemblies may also be required to have recesses sized and shaped to accommodate the various sizes and shapes of pictures to be inserted. This further increases manufacturing costs.

In the following description, certain specific details are set forth in order to provide a thorough understanding of various disclosed embodiments. However, one skilled in the relevant art will recognize that embodiments may be practiced without one or more of these specific details, or with other methods, components, materials, etc. In other instances, well-known structures associated with frames and related frame assemblies have not been shown or described in detail to avoid unnecessarily obscuring descriptions of the embodiments.

Unless the context requires otherwise, throughout the specification and claims which follow, the word "comprise" and variations thereof, such as, "comprises" and "comprising" are to be construed in an open, inclusive sense, that is, as "including, but not limited to."

Reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

As used in this specification and the appended claims, the singular forms "a," "an," and "the" include plural referents unless the content clearly dictates otherwise. It should also be noted that the term "or" is generally employed in its sense including "and/or" unless the content clearly dictates otherwise.

Figures 1 through 6 illustrate a frame assembly 10 according to one embodiment. The frame assembly 10 includes a base frame 12 and a picture holder assembly 14. The base frame 12 is coupleable to a hanging structure, such as a wall, a door, a ceiling, and other similar structures. The picture holder assembly 14 is detachably coupleable to the base frame 12.

The base frame 12 includes a recess 16 that is formed by peripheral sidewalls 18, 20, 22, 24 that extend upwardly relative to a base plate 26. Each of the sidewalls 18, 20, 22, 24 includes a pair of leg peripheral cavities 28 extending therethrough. Each of the sidewalls 18, 20, 22, 24 also includes a plurality of clip peripheral cavities 30. The clip peripheral cavities 30 are located adjacent to and on either side of the leg peripheral cavities 28. Each of the clip peripheral cavities 30 are equidistantly spaced apart relative to a central reference plane Rp of the leg peripheral cavities 28. While the embodiment illustrated in Figures 1 through 6 includes a plurality of leg and clip peripheral cavities 28, 30, respectively, in alternative embodiments, the base frame 12 may include one leg and clip peripheral cavity 28, 30, or may include any number of leg and clip peripheral cavities 28, 30, respectively.

As best illustrated in Figure 4, at a back side of the base frame 12, the sidewalls 18, 20, 22, 24 include respective elongated recesses 32, 34, 36, 38. The elongated recesses 32, 34, 36, 38 extend only through a portion of the respective sidewalls 18, 20, 22, 24. The elongated recesses 32, 34, 36, 38 are generally sized (i.e., width, length) to extend beyond the distal clip peripheral cavities 30 of the respective sidewalls 18, 20, 22, 24 to define clip receiving surfaces 40, 42, 44, 46, which are thus formed at the back side of the base frame 12.

With continued reference to Figures 1 through 6, the base frame 12 includes base frame corner extensions 48 that extend upwardly relative to the base plate 26. The base frame corner extensions 48 are generally L- shaped and are formed proximal to the locations where the outer sides of the sidewalls 18, 20, 22, 24 intersect one another. The upward extension of the base frame corner extensions 48 forms a notch between each of the base frame corner extensions 48, which is discussed in more detail elsewhere.

Within the recess 16, the base frame 12 includes a first fastener guide 50, which extends outwardly from the base plate 26. The first fastener guide 50 is annular, having an aperture 52 extending therethrough. The aperture 52 is configured to allow a nail or other fastening means to extend therethrough when coupling the base frame 12 to the hanging structure. The first fastener guide 50 may be integral to the base frame 12. For instance, the first fastener guide 50 may be injection molded portions of a single, integrally formed base frame 12. Injection molding of the base frame 12 may include a single shot or multi-shot process and may include one or more materials. In other instances, the base frame 12 may be formed via an additive

manufacturing process or other process. Alternatively, the first fastener guide 50 may be coupled to the base frame 12. By way of example, the first fastener guide 50 may be fastened or adhered to the base plate 26. Further, while the embodiment illustrated in Figures 1 through 6 includes a first fastener guide 50, in alternate embodiments, the base frame 12 may include any number of first fastener guides 50.

The base frame 12 also includes a pair of second fastener guides 54. The second fastener guides 54 are located proximal to the periphery of the base plate 26 and are a mirror image, simply reflected about a central horizontal reference plane H _P of the base frame 12. The second fastener guides 54 include a plurality of first guide apertures 56 and second guide apertures 58. The first and second guide apertures 56, 58 have different diameters and generally form a staggered pattern. The diameters of the first and second guide apertures 56, 58 may be sized to accommodate a wide variety of screws, nails, or other fastening means to couple the base frame 12 to the hanging structure. By way of example, the first guide apertures 56 may have diameters to allow a Walldog type screw or anchor to extend

therethrough, with a head of the screw, for example, that may be seated on an upper face of the second fastener guide 54. Similarly, the second guide apertures 58 may have diameters to allow a bolt or a Philips™ head screw to extend therethrough, with a head of the screw, for example, that may be seated on the upper face of the second fastener guide 54. Alternatively, the second fastener guide 54 may include a wide variety of apertures, with such apertures having a multitude of diameters to accommodate a wide variety of fastening means.

Again, the second fastener guides 54 may be integral to the base frame 12. For instance, the second fastener guides 54 may be injection molded portions of a single, integrally formed base frame 12. Injection molding of the base frame 12 may include a single shot or multi-shot process and may include one or more materials. In other instances, the base frame 12 may be formed via an additive manufacturing process or other process. Alternatively, the second fastener guides 54 may be coupled to the base frame 12. By way of example, the second fastener guides 54 may be fastened or adhered to the base plate 26. Further, while the embodiment illustrated in Figures 1 through 6 includes a pair of second fastener guides 54, in alternate embodiments, the base frame 12 may include any number of second fastener guides 54.

At a lower portion, the base frame 12 includes a pair of spaced apart L-shaped brackets 60 that define a level holder 61 . A base flange of the L-shaped bracket 60 may have a substantially flat surface which may further be parallel to a substantially level and horizontal surface. Such horizontal surfaces may include, for example, a floor structure or an outer or inner surface of the sidewalls 20, 24. More particularly, the base flange of the L-shaped brackets 60 is adapted to receive a level. The level may be a bubble level, digital level, or other types of devices. The L-shaped brackets 60 advantageously allow a user to orient the base frame 12 and, thus, the frame assembly 10, such that they are level relative to a reference horizontal plane of the horizontal surface, such as the floor structure, for example. By way of example, the user may first position the base frame 12 over the hanging structure. Prior to coupling the base frame 12 to the hanging structure, the user may securely place the level within the level holder 61 and make adjustments until the base frame 12 is level with the reference horizontal plane.

The L-shaped brackets 60 may be integral to the base frame 12. For instance, the L-shaped brackets 60 may be injection molded portions of a single, integrally formed base frame 12. Injection molding of the base frame 12 may include a single shot or multi-shot process and may include one or more materials. In other instances, the base frame 12 may be formed via an additive manufacturing process or other process. Alternatively, the L-shaped brackets 60 may be coupled to the base frame 12. By way of example, the L-shaped brackets 60 may be fastened or adhered to the base plate 26. Further, while the embodiment illustrated in Figures 1 through 6 includes a pair of L-shaped brackets 60, in alternate embodiments, the base frame 12 may include any number of L-shaped brackets 60.

With continued reference to Figures 1 through 6, the picture holder assembly 14 includes an exterior border portion 62, a holder 64, and a cover 66. The exterior border portion 62 includes side elements 68, 70, 72, 74 that are positioned at a periphery of the exterior border portion 62, thereby forming a boundary with an opening 76 therebetween. The side elements 68, 70, 72, 74 include respective base flanges 78, 80, 82, 84. The side elements 68, 70, 72, 74 also include respective upstanding flanges 86, 88, 90, 92 that extend substantially perpendicularly from the respective base flanges 78, 80, 82, 84. Each of the upstanding flanges 86, 88, 90, 92 includes at least a pair of legs 94 coupled to respective interior sides of the upstanding flanges 86, 88, 90, 92. The legs 94 are generally tapered and include a leg lip 96 located at its lower end. The legs 94 are sized (i.e., length, width, depth) and positioned such that the legs 94 are securely received in the leg peripheral cavities 28. As best seen in Figure 6, when the legs 94 are received in the leg peripheral cavities 28, the leg lips 96 are seated over the clip receiving surfaces 40, 42, 44, 46 (clip receiving surfaces 40, 44 shown in Figure 6), thus making frictional contact to secure the exterior border portion 62 to the base frame 12. The legs 94 may be elastically deformable and formed of materials that have suitable moduli of elasticity. Examples may include plastic, aluminum, or similar materials. In this manner, a user may simply press the exterior border portion 62 over the base frame 12 to couple the exterior border portion 62 to the base frame 12. Likewise, the user may simply depress the legs 94 to uncouple the exterior border portion 62 from the base frame 12, or may simply pull the exterior border portion 62 to uncouple from the base frame 12.

While the embodiment illustrated in Figures 1 through 6 couples the exterior border portion 62 to the base frame 12 through the legs 94, in alternative embodiments, the exterior border portion 62 may be coupled through other coupling means. Such means may include, for example, magnets, other types of male connectors that can snap into place when matingly received by a female connector located in the base frame 12, any number of posts or pegs that may be received by holes or dents in the base frame 12 to detachably couple the exterior border portion 62 to the base frame 12. As can be appreciated from the foregoing, other mechanisms may be used to detachably couple the exterior border portion 62 to the base frame 12.

Again, the legs 94 may be integral to the exterior border portion 62. For instance, the legs 94 may be injection molded portions of a single, integrally formed exterior border portion 62. Injection molding of the exterior border portion 62 may include a single shot or multi-shot process and may include one or more materials. In other instances, the exterior border portion 62 may be formed via an additive manufacturing process or other process. Alternatively, the legs 94 may be coupled to the exterior border portion 62. By way of example, the legs 94 may be fastened or adhered to respective interior sides of the upstanding flanges 86, 88, 90, 92. Further, while the embodiment illustrated in Figures 1 through 6 includes a pair of legs 94 on each interior side of the upstanding flanges 86, 88, 90, 92, in alternate embodiments, the exterior border portion 62 may include any number of legs 94.

The exterior border portion 62 also includes border corner extensions 97 that extend downwardly relative to the base flanges 78, 80, 82, 84 of the respective side elements 68, 70, 72, 74. The border corner extensions 97 are generally L-shaped and are formed proximal to the locations where the side elements 68, 70, 72, 74 intersect one another. The downward extension of the border corner extensions 97 forms a notch between each of the border corner extensions 97. In this manner, when the exterior border portion 62 is coupled to the base frame 12, the border corner extensions 97 abut and make contact with the complementary base frame corner extensions 48 to form respective access openings 98. The access openings 98

advantageously provide the user access to the legs 94 when the exterior border portion 62 is coupled to the base frame 12. The user may simply depress the legs 94 to uncouple the exterior border portion 62 from the base frame 12, as discussed in further detail elsewhere. Further, the access openings 98 also allow the user access to grip the exterior border portion 62 during removal, for example.

The interior sides of the upstanding flanges 88, 92 include respective slot elements 99. The slot elements 99 extend outwardly relative to the respective interior sides of the upstanding flanges 88, 92, thereby forming respective slots 100. Again, the slot elements 99 may be integral to the exterior border portion 62. For instance, the slot elements 99 may be injection molded portions of a single, integrally formed exterior border portion 62. Injection molding of the exterior border portion 62 may include a single shot or multi-shot process and may include one or more materials. In other instances, the exterior border portion 62 may be formed via an additive manufacturing process or other process. Alternatively, the slot elements 99 may be fastened or adhered to the interior sides of the upstanding flanges 88, 92. Further, in some embodiments, the exterior border portion 62 may have a notch in the interior sides of the upstanding flanges 88, 92, 64 in lieu of slot elements 99. The notch may be a female member sized to receive a corresponding male member.

With continued reference to Figures 1 through 6, the holder 64 includes a base plate 102 and holder side elements 103, 104, 105, 106 that each extend substantially perpendicularly to the base plate 102. The holder side elements 103, 104, 105, 106 are positioned at a periphery of the base plate 102, thereby forming a boundary. The holder 64 is sized (i.e., length, width, depth) such that it may be received by the exterior border portion 62.

At a generally central portion of the side elements 103, 105, the side elements 103, 105 have respective channel shaped contours, where hook elements 107 are located. The hook elements 107 have a generally U-shaped portion and an angular flange 108 extending outwardly relative to an outer face of the U-shaped portion. The angular flange 108 is generally tapered and oriented at an angle relative to the outer face of the U-shaped portion. This angle may vary anywhere between 91 degrees to 105 degrees. The angular flange 108 is configured to be received by the respective slots 100. More particularly, as best illustrated in Figure 5, the angular orientation and the taper of the angular flange 108 is configured such that when received in the respective slots 100, it causes a downward force to be applied to the angular flanges 108 which secures the holder 64 to the exterior border portion 62. Additionally, the downward force causes a reactionary upward force at the base plate 102. This reactionary force advantageously fixedly secures a picture or other objects that may be positioned between the holder 64 and other abutting structures (i.e., the cover 66). In some embodiments, the respective slots 100 may also be angled to apply pressure to secure the picture or other objects positioned between the holder 64 and other abutting structures.

While the embodiment illustrated in Figures 1 through 6 couples the holder 64 to the exterior border portion 62 through the hook elements 107, in alternative embodiments, the holder 64 may be coupled through other coupling means. Such means may include, for example, magnets, other types of male connectors that can snap into place when matingly received by a female connector located in the exterior border portion 62, any number of posts or pegs that may be received by holes or dents in the exterior border portion 62 to detachably couple the holder 64 to the exterior border portion 62. As can be appreciated from the foregoing, other mechanisms may be used to detachably couple the holder 64 to the exterior border portion 62.

Again, the hook elements 107 may be integral to the holder 64. For instance, the hook elements 107 may be injection molded portions of a single, integrally formed holder 64. Injection molding of the holder 64 may include a single shot or multi-shot process and may include one or more materials. In other instances, the holder 64 may be formed via an additive manufacturing process or other process. Alternatively, the hook elements 107 may be coupled to the holder 64. By way of example, the hook elements 107 may be fastened or adhered to respective side elements 103, 105. Further, while the embodiment illustrated in Figures 1 through 6 includes a pair of hook elements 107, in alternate embodiments, the holder 64 may include any number of hook elements 107. The hook elements 107 may be elastically deformable and formed of materials that have suitable moduli of elasticity. Examples may include plastic, aluminum, or similar materials. In this manner, a user may simply depress the U-portion of the hook elements 107 to couple the holder 64 to the exterior border portion 62 and release the U-portion when the angular flange 108 is received by the respective slots 100. Likewise, the user may simply depress the U-portion of the hook elements 107 and release the U- portion when the angular flange 108 is no longer seated in the respective slots 100 to uncouple the holder 64 from the exterior border portion 62.

With continued reference to Figures 1 through 6, the cover 66 may be formed of transparent or translucent materials, such as clear plastic or glass, to allow viewers to see through the cover 66. The cover 66 is positioned between the holder 64 and the exterior border portion 62. More particularly, a picture or other object is secured between the cover 66 and the holder 64. In this manner, the user may advantageously orient the picture in any desired orientation, such as vertically, diagonally, horizontally, or other orientations. Moreover, the picture or other object may be of any suitable size which may be simply secured between the holder 64 and the cover 66.

In use, the user may position the base frame 12 over the hanging structure. The user may then position a level (i.e., a bubble or digital level) within the level holder 61 and make adjustments to the base frame 12 until a level orientation is obtained. The user may then couple the base frame 12 to the hanging structure via fastening means. The user may, for example, use first and/or second fastener guides 50, 54 to couple the base frame 12 to the hanging structure via fasteners (i.e., nails, screws, anchors, etc.).

Prior to or after coupling the base frame 12 to the hanging structure, the user may position a picture or other object between the cover 66 and the holder 64, orienting the picture or other object in the desired manner. The user may then simply depress the hook elements 107 until the hook elements 107 are securely received by the slots 100 to couple the cover 66 and the holder 64 with a picture secured therebetween, to the exterior border portion 62. Alternatively, the user may simply press the cover 66 and the holder 64 with a picture secured therebetween over the exterior border portion 62, wherein the downward force may elastically deform the hook elements 107 until the holder 64 snaps into the exterior border portion 62. The user may then position the picture holder assembly 14 over the base frame 12 and depress the legs 94 until the legs 94 are securely seated over the clip receiving surfaces 40, 42, 44, 46 to couple the picture holder assembly 14 to the base frame 12.

Alternatively, the user may simply press the picture holder assembly 14 over the base frame 12, wherein the downward force may elastically deform the legs 94 until the picture holder assembly 14 snaps into the base frame 12. Thus, the user may simply remove the picture holder assembly 14 from the base frame 12 during removal. The user may then remove the holder 64 from the exterior border portion 62 and remove and replace the pictures, as desired, and then in a similar manner couple the picture holder assembly 14 to the base frame 12.

Figures 7 and 8 illustrate a system 200 of frame assemblies 10 coupled to a wall 1 1 , with certain components (i.e., holders, covers, fastening means, exterior border portions, etc.) removed for clarity. The frame

assemblies 10 are positioned adjacent to and abutting one another. The frame assemblies 10 are coupled to one another with a clip 1 10. As best illustrated in Figures 1 , 7, and 8, the clip 1 10 includes a base flange 1 12 and a pair of upstanding flanges 1 14. A central portion of the base flange 1 12 includes a leg cavity 1 16. The upstanding flanges 1 14 are substantially perpendicular to the base flange 1 12 and substantially parallel to each other. The upstanding flanges 1 14 are spaced apart and include clip lips 1 18 at their respective lower ends.

As best illustrated in Figure 8, the upstanding flanges 1 14 are adapted to extend through the clip peripheral cavities 30 of adjacent frame assemblies 10, wherein the clip lips 1 18 are seated over the clip receiving surfaces 40, 42, 44, 46 (clip receiving surfaces 40 and 44 shown in Figure 8). The clip lips 1 18 thus make frictional contact to secure the adjacent and abutting frame assemblies 10 to one another. Again, the upstanding flanges 1 14 may be elastically deformable and formed of materials that have suitable moduli of elasticity. Examples may include plastic, aluminum, or similar materials. In this manner, a user may simply press the clips 1 10 over the adjacent and abutting frame assemblies 10 to couple them to one another. Likewise, the user may simply remove the clips 1 10 to uncouple the frame assemblies 10 from one another. In this manner, the user may properly align adjacent and abutting frame assemblies 10 without further measurements, leveling methods, etc., and create an aesthetically pleasing pattern. Further, in some implementations, the user may also use additional fastening means to couple one or more of the base frames 12 of the frame assemblies 10 to the hanging structure.

Figure 9 illustrates another example embodiment of a system 300 of frame assemblies 10. The system 300 illustrates a variation in which the frame assemblies 10 are coupled to the wall 1 1 and positioned at an offset to each other. In particular, in such an offset system 300 of frame assemblies 10, the clip 1 10 allows the legs 94 of the exterior border portions 62 to extend through the leg cavity 1 16, in order to avoid interference when coupling the picture frame assembly 14 to the base frame 12.

Figure 10 illustrates another example embodiment of a system

400 of frame assemblies 10. The system 400 illustrates a variation in which a plurality of frame assemblies 10 are coupled to the wall 1 1 and positioned in an abstract manner to create an aesthetically pleasing pattern of frame assemblies 10. Moreover, as can be appreciated, the illustrated pattern of frame

assemblies 10 is one of numerous patterns that may be formed.

The various embodiments described above can be combined to provide further embodiments. Moreover, the various components described herein may advantageously be provided as a kit. The kit may, for example, include a frame assembly having a base frame, a plurality of fastening means (i.e., screws, nails, anchors, etc.) and a picture holder assembly having an exterior border portion, a cover, and a holder. In some implementations, the kit may also include a set of instructions for assembling the frame assembly. The kit may also include a plurality of frame assemblies and connectors for interconnecting the plurality of frame assemblies. The kit may also include a level that is coupleable to the frame assembly. The level may be a digital or a bubble type level.
