Description

CROSS REFERENCE TO RELATED APPLICATION

[0001] This application claims the benefit of pending U.S. Provisional Application No. 63 / 751,307 filed on January 30, 2025; the above identified patent application is herein incorporated by reference in its entirety. BACKGROUND OF THE INVENTION

[0002] The present invention relates generally to systems and assemblies for mounting pictures, artwork, signage, or other planar substrates to vertical surfaces, and more particularly to modular picture mounting assemblies that provide secure attachment, ease of installation, alignment accuracy, and long-term structural stability while accommodating a variety of substrate sizes, weights, and orientations.

[0003] Methods for mounting pictures and similar substrates to walls are well known and widely used in residential, commercial, and institutional environments. Common mounting approaches include nails, screws, hooks, eyelets, wires, sawtooth hangers, keyhole slots, adhesive pads, and cleat-based systems such as French cleats. While these solutions are prevalent, each presents notable limitations that can detract from usability, aesthetics, and long-term performance. For example, nail and hook-based systems often require precise placement to achieve level alignment, and even minor installation errors can result in visibly crooked displays. Correcting such misalignment typically involves repeated removal and repositioning of fasteners, which can damage wall surfaces and frustrate users.

[0004] Wire and eyelet based hanging systems are similarly limited, as they depend heavily on proper tensioning and precise wall fastener placement. These systems may allow frames to tilt, rotate, or shift over time, particularly when subjected to vibration, accidental contact, or environmental changes such as humidity and temperature fluctuations. Additionally, many wire-based systems restrict the orientation of the substrate, making it difficult to switch between portrait and landscape configurations without reinstalling wall hardware.

[0005] Adhesive-based mounting solutions attempt to simplify installation by eliminating mechanical fasteners, but such solutions often suffer from limited load capacity, inconsistent adhesion across different wall surfaces, and degradation over time. Adhesive mounts may fail unexpectedly, risking damage to the substrate or surrounding area, and are frequently unsuitable for larger or heavier items. Furthermore, adhesives can leave residue or cause surface damage upon removal.

[0006] Cleat-based mounting systems, including French cleats, offer improved load distribution and stability compared to simpler hanging methods. However, many existing cleat systems are designed primarily for cabinetry or large fixtures and are not optimized for picture mounting applications. Such systems often require precise leveling during installation, rely on external leveling tools, and may lack features that prevent unintentional disengagement once mounted. In addition, conventional cleat systems typically do not address substrate warping or bending, particularly for large or thin substrates that are susceptible to bowing away from the wall over time.

[0007] Another limitation of existing picture mounting solutions is the lack of modularity and adaptability. Many frames and mounts are designed for specific sizes or configurations, requiring users to purchase different products for different substrates. Existing solutions also frequently fail to conform to uneven wall surfaces, resulting in gaps, instability, or visual imperfections. Moreover, aesthetic considerations are often secondary to function, with limited options for edge profiles, finishes, or presentation styles.

[0008] As a result of these shortcomings, there exists a need for a picture mounting assembly that provides secure and repeatable alignment without requiring excessive precision during installation, that resists warping and misalignment over time, and that accommodates a wide range of substrate sizes and orientations. There is further a need for such a system to incorporate features that prevent accidental dislodgment, allow for simplified mounting and removal, and provide enhanced structural rigidity while remaining visually unobtrusive. The present invention addresses these needs by providing a modular picture mounting assembly that overcomes the deficiencies of prior art solutions while improving ease of use, stability, and versatility within the broader field of wall-mounted display systems.

[0009] In light of the devices disclosed in the known art, it is submitted that the present invention substantially diverges in design elements and methods from the known art and consequently it is clear that there is a need in the art for an improvement for a picture mounting assembly. In this regard the instant invention substantially fulfills these needs.SUMMARY OF THE INVENTION

[0010] In view of the foregoing disadvantages inherent in the known types of picture mounting assemblies now present in the known art, the present invention provides a new picture mounting assembly for easily mounting a picture to a wall in multiple configurations.

[0011] It is an objective of the present invention to provide a picture mounting assembly configured to securely support a substrate on a vertical surface. The picture mounting assembly includes a frame assembly and a wall mounting member that cooperate through complementary cleat structures to provide removable yet stable engagement. This configuration distributes load across the substrate to reduce localized stress and prevent sagging, bending, or warping over time. The structural relationship between the frame assembly and the wall mounting member enables reliable support for substrates of varying sizes and weights.

[0012] It is an objective of the present invention to provide a picture mounting assembly wherein the wall mounting member may include an integrated level to facilitate accurate horizontal positioning without reliance on external tools. The cleat-based engagement allows the frame assembly to be mounted and removed repeatedly while maintaining consistent alignment.

[0013] It is an objective of the present invention to provide a picture mounting assembly comprising a modular frame assembly formed from a plurality of frame sections arranged to define a perimeter. The frame sections may interlock to form an enclosed geometry corresponding to the shape of the substrate. This modular construction permits scalability for different substrate dimensions while maintaining structural continuity around the perimeter.

[0014] It is an objective of the present invention to provide a picture mounting assembly that accommodates multiple mounting configurations and orientations. The cleat engagement permits the frame assembly to be supported in portrait or landscape orientation without repositioning the wall mounting member. The structure further allows for flush or standoff mounting configurations depending on frame geometry and cleat selection. This adaptability increases functional versatility while maintaining consistent structural performance.

[0015] It is an objective of the present invention to provide a picture mounting assembly comprising complementary cleat profiles configured to engage at defined angles. In certain embodiments, the cleat profiles define an interlocking ninety-degree configuration to enhance structural stability and conform the substrate to uneven wall surfaces. In other embodiments, the cleat profiles define an interlocking forty-five-degree configuration to reduce material usage while maintaining sufficient engagement strength. The selectable cleat geometries enable optimization based on substrate size and performance requirements.

[0016] It is an objective of the present invention to provide a picture mounting assembly comprising a substrate retention interface disposed on the frame assembly. The retention interface may include an adhesive layer configured to secure the substrate to the frame assembly without mechanical fasteners penetrating the substrate. This configuration enables clean presentation, simplified mounting, and controlled removal or replacement of the substrate.

[0017] It is an objective of the present invention to provide a picture mounting assembly that incorporates structural locking embodiments to resist unintended disengagement. In one embodiment, the assembly includes a snap-lock feature configured to mechanically interfere with removal of the frame assembly once engaged with the wall mounting member. In another embodiment, a tool-actuated T-screw locking mechanism secures a lower portion of the frame assembly relative to the wall.

[0018] It is an objective of the present invention to provide a picture mounting assembly comprising radiused or profiled frame edges. The profiled edges reduce sharp transitions that may interfere with or damage the rear surface of the substrate. This configuration further minimizes stress concentrations and improves compatibility with rigid substrate materials.

[0019] It is therefore an object of the present invention to provide a new and improved picture mounting assembly that has all of the advantages of the known art and none of the disadvantages.

[0020] Other objects, features and advantages of the present invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings. BRIEF DESCRIPTIONS OF THE DRAWINGS

[0036] Reference is made herein to the attached drawings. For the purpose of presenting a brief and clear description of the present invention, the preferred embodiment will be discussed as used for mounting a picture to a wall. The figures are intended for representative purposes only and should not be considered to be limiting in any respect.

[0037] Reference will now be made in detail to the exemplary embodiment (s) of the invention. References to “one embodiment,”“at least one embodiment,”“an embodiment,”“one example,”“an example,”“for example,” and so on indicate that the embodiment(s) or example(s) may include a feature, structure, characteristic, property, element, or limitation but that not every embodiment or example necessarily includes that feature, structure, characteristic, property, element, or limitation. Further, repeated use of the phrase “in an embodiment,”“first embodiment,”“second embodiment,” or “third embodiment” does not necessarily refer to the same embodiment.

[0038] Referring now to FIGS. 1 and 2, there is shown an exploded perspective view of a first embodiment of the picture mounting assembly showing a frame assembly, a wall mounting member, and a substrate prior to assembly and a rear view of the first embodiment of the picture mounting assembly in an assembled configuration, respectively. The picture mounting assembly 1000 comprises a frame assembly 1100 configured to support a planar substrate 1200, such as a photograph, artwork, sign, panel, or similar display material. In some embodiments, the planar substrate 1200 may be formed from paper, cardboard, canvas, polymeric sheets, metal sheets, wood, composite materials, or combinations thereof. In some embodiments, the picture mounting assembly includes the substrate, whereas in other embodiments, the picture mounting assembly does not include the substrate.

[0039] The frame assembly 1100 includes a plurality of frame sections 1110 arranged to define a perimeter corresponding generally to the outer boundary of the substrate 1200. The outer perimeter of the frame sections 1110 is within the outer boundary of the substrate 1200 to conceal the frame assembly 1100 when the substrate 1200 is attached thereto and the picture mounting assembly 1000 is secured to a wall. In the illustrated embodiment, the frame sections 1110 form a closed geometric shape, such as a rectangle or square, though other shapes are contemplated. In the illustrated embodiments, the frame assembly may be formed from rigid sheet material using precision cutting processes, including CNC machining. In certain embodiments, the sheet material is cut unilaterally from a single side to preserve material continuity and rigidity. Suitable materials include polymeric materials, wood-based materials, composite materials, metals, and combinations thereof.

[0040] Each frame section 1110 includes a frame cleat 1120 disposed along at least a portion of its length. The frame cleat 1120 is an elongate structural feature configured to engage a complementary mounting cleat 1320 provided on a wall mounting member 1300. In the illustrated embodiment, the frame cleat 1120 is integrally formed with the frame section 1110 and is oriented such that each frame section 1110 is capable of receiving the wall mounting member 1300 along any selected side of the frame assembly 1100. This configuration permits the frame assembly 1100 to be mounted in multiple orientations, including portrait and landscape orientations, without repositioning the wall mounting member 1300. The frame cleat 1120 further defines a receiving interface that allows the frame assembly 1100 to be selectively seated onto and removed from the wall mounting member 1300 while maintaining consistent alignment and load distribution across the frame assembly. In some embodiments, the frame cleat 1120 is a rabbet formed along an outward side of the frame 1100.

[0041] The wall mounting member 1300 is configured for attachment to a wall or other vertical surface using one or more fasteners, such as screws, nails, anchors, or equivalent mechanical fasteners. The wall mounting member 1300 includes one or more fastener openings 1330 configured to receive the fasteners. In the illustrated embodiment, the wall mounting member 1300 is an elongate body having a generally linear profile extending along a longitudinal axis, the length of the wall mounting member 1300 is selected to support and distribute the load of the frame assembly 1100 when mounted. In certain embodiments, the wall mounting member 1300 has a length less than or equal to a width of the frame assembly 1100, depending on the size and weight of the planar substrate 1200. The wall mounting member 1300 may have a generally rectangular cross-sectional shape, though other cross-sectional shapes, including trapezoidal, stepped, or profiled geometries, are contemplated to accommodate the mounting cleat 1320 and associated structural features. In certain embodiments, the wall mounting member 1300 further includes a level 1350 integrated therein to facilitate horizontal alignment during installation.

[0042] In the shown embodiment, wall mounting member 1300 includes the mounting cleat (rabbet) on a wall face, which is opposite the frame cleat 1120. Additionally, the thickness of the wall mounting member 1300 and frame 1100 are generally equivalent and the cleat width and thickness are complimentary. In this way, when the cleats 1120, 1320 are cooperatively engaged, they are substantially mating without either protruding.

[0043] The frame assembly 1100 is removably supported on the wall mounting member 1300 by engagement between the frame cleat 1120 and the mounting cleat 1320. In the illustrated embodiment, the frame cleat 1120 and the mounting cleat 1320 define complementary cleat profiles that engage at a combined angle of approximately ninety degrees. This ninety-degree cleat configuration increases rigidity of the mounted assembly and allows the frame assembly 1100 to conform more closely to irregularities in the wall surface. The ninety-degree configuration is particularly suited for larger or heavier planar substrates 1200, where resistance to warping and long-term misalignment is desired. The cleats 1120, 1320 are configured to cooperate such that gravitational forces bias the frame assembly 1100 into a seated position when mounted, thereby distributing load across the perimeter of the planar substrate 1200 and resisting localized stress concentrations that may cause warping or bending.

[0044] The frame assembly 1100 further includes a substrate retention surface 1130 positioned to contact a rear surface of the planar substrate 1200. In certain embodiments, an adhesive layer 1140 is disposed on the substrate retention surface 1130. The adhesive layer 1140 may extend across an entirety of the substrate retention surface 1130 or may be applied to one or more discrete regions thereof, including strips, pads, dots, or patterned areas, depending on the desired retention strength and substrate characteristics. The adhesive layer 1140 may be formed from pressure-sensitive adhesive, removable adhesive, repositionable adhesive, or combinations thereof, and is configured to secure the planar substrate 1200 to the frame assembly 1100 without penetrating the substrate. In some embodiments, the adhesive layer 1140 is covered by a removable release liner prior to use. This configuration permits clean presentation, accommodates substrates of varying materials and thicknesses, and enables controlled removal or replacement of the planar substrate 1200 without damage. In alternate embodiments, any suitable fastener is used to secure the substrate to the frame assembly, such as hook and look material.

[0045] In the illustrated embodiment, each of the frame sections 1110 are interlocking frame sections. Each interlocking frame section 1110 includes a first end 1112 having a protrusion and a second end 1114 having a complementary recess, such that adjacent frame sections mechanically interlock to form an enclosed frame geometry. The interlocking structure provides positional stability during assembly and enhances structural continuity around the perimeter of the planar substrate 1200.

[0046] Referring now to FIG. 3, there is shown a rear elevational view of a second embodiment of the picture mounting assembly in an assembled configuration. In this embodiment, one or more frame sections 1110 include a profiled or radiused edge 1150 formed along at least a portion of an exposed edge of the frame assembly 1100. The profiled or radiused edge 1150 reduces sharp transitions along the frame assembly 1100, particularly when the frame sections 1110 are formed from rigid materials. This configuration minimizes concentrated contact points between the frame assembly 1100 and a rear surface of the planar substrate 1200, thereby reducing the likelihood of surface marring, stress-induced deformation, or damage to the substrate during mounting or long-term use. The profiled or radiused edge 1150 further facilitates improved fitment and tolerance accommodation between the frame assembly 1100 and the planar substrate 1200, while maintaining consistent structural support across the substrate.

[0047] Referring to FIG. 4, there is shown a rear elevational view of a third embodiment of the picture mounting assembly in an assembled configuration. In this embodiment, the frame assembly 1100 includes an alternative hanging feature formed independently of the wall mounting member. The alternative hanging feature comprises one or more notches 1510 formed in an interior side of at least one frame section 1110. Each notch 1510 defines a recessed geometry configured to receive and retain a head portion of a wall fastener, such as a nail, hook, screw, or other generic wall-mounted support element. The notch 1510 may include a V-shaped profile, a keyhole-shaped profile, a stepped recess, or a curved retention surface, such that the frame assembly 1100 is guided into a seated position when lowered onto the fastener.

[0048] In certain embodiments, the notch 1510 includes a narrowed upper opening and an enlarged lower retention region to resist lateral displacement after installation. In further embodiments, multiple notches 1510 are spaced along the frame section to distribute load and maintain level orientation, particularly for larger or heavier planar substrates 1200. This alternative hanging configuration allows the frame assembly 1100 to be directly suspended without engagement of the frame cleat and mounting cleat, while preserving structural stability and compatibility with the modular frame assembly.

[0049] Referring now to FIGS. 5-7, there is shown a front perspective view of a fourth embodiment of the picture mounting assembly in an assembled configuration, a front exploded view of the fourth embodiment of the picture mounting assembly, and a rear perspective view of a wall member of the fourth embodiment of the picture mounting assembly, respectively. In this embodiment, the wall mounting member 1300 includes a locking member 1400 configured to inhibit unintended disengagement of the frame assembly 1100 from the wall mounting member 1300 after installation. In the illustrated embodiment, the locking member 1400 comprises a snap-fit geometry formed on or adjacent to the mounting cleat 1320 of the wall mounting member 1300. The locking member 1400 is configured to elastically deform as the mounting cleat 1320 is advanced through a corresponding opening or modified region 1116 of a frame section 1110, and to resiliently return to a locked position once fully seated on an opposite side thereof. In the shown embodiment, the modified region 1116 of the frame section 1110 is a cutout sized to receive the locking member 1400 therethrough.

[0050] In the locked position, the locking member 1400 mechanically interferes with a retention surface of the frame assembly 1100, thereby resisting upward or outward movement that could otherwise result from accidental impact or applied forces. In the shown embodiment, the locking member 1400 comprises a pair of flexible arms 1410. However, in alternate embodiments, as seen in FIGS. 8-10, the locking member may include one or more flexible arms, tabs, latches, or projections configured to elastically deform during engagement and to generate a retaining force upon return to an undeformed state. The specific bias direction and geometry may be selected based on material selection, desired retention force, and ease of release.

[0051] The locking member 1400 is positioned such that it may be manually deflected from an accessible edge adjacent to the substrate to permit intentional release of the frame assembly 1100 from the wall mounting member 1300. In certain embodiments, the snap-fit geometry is formed from a resilient polymeric material, while the wall mounting member 1300 or frame section 1110 may be formed from a more rigid material, such that a combination of materials is employed to balance structural strength and elastic deformation. This locking configuration provides secure retention while maintaining removability of the picture mounting assembly.

[0052] In further embodiments, the snap-fit geometry may comprise an inward-biased snap member configured to deflect toward the mounting cleat 1320 during engagement, an outward-biased snap member configured to deflect away from the mounting cleat 1320, or a cantilevered snap member extending from the wall mounting member 1300 or the frame assembly 1100. In certain embodiments, the snap-fit geometry and the corresponding retention surface are dimensioned to define a clearance or interference fit within a predetermined tolerance range. The tolerance range accommodates manufacturing variation, material expansion, and repeated engagement cycles while maintaining reliable locking performance. In some embodiments, the snap-fit geometry defines a lead-in surface, ramped surface, or chamfered edge to facilitate guided insertion and controlled deflection during engagement. This dimensional configuration ensures consistent snap engagement while resisting unintentional disengagement caused by vibration, impact, or applied loads.

[0053] Referring now to FIGS. 11, 12, and 13, there is shown an elevational view of a sixth embodiment of the picture mounting assembly in an assembled configuration, a perspective view of the sixth embodiment of the picture mounting assembly in an assembled configuration, and an exploded view of the sixth embodiment of the picture mounting assembly, respectively. In the illustrated embodiment, an alternate locking member 1440 is provided to secure the frame assembly 1100 relative to a wall. The alternate locking member 1440 comprises a T-screw 1442 positioned adjacent to a lower portion of the frame assembly 1100 and configured to engage a fastener or anchor secured directly to the wall. The T-screw 1442 is configured to pass through a corresponding opening or modified region 1116 of a frame section 1110.

[0054] The T-screw 1442 includes a head portion having a transverse profile and a threaded shaft configured to permit rotational actuation using an external tool, such as a wrench or driver. During installation, the frame assembly 1100 is first supported at an upper region by engagement between the frame cleat and the mounting cleat of the wall mounting member 1300. The T-screw 1442 is then rotated into a locking orientation such that the head portion captures behind or beneath a wall-anchored fastener, thereby restraining a lower region of the frame assembly 1100.

[0055] In the locked configuration, the frame assembly 1100 is retained at the top by the wall mounting member 1300 and at the bottom by the T-screw 1442, forming a dual-point retention system that inhibits upward movement, outward displacement, or rocking of the frame assembly 1100 relative to the wall. In certain embodiments, the T-screw 1442 is removable or selectively disengageable to permit intentional removal of the frame assembly 1100. This configuration enhances resistance to accidental dislodgement due to impact or vibration while maintaining controlled removability.

[0056] Referring now to FIG. 14, there is shown an exploded view of a seventh embodiment of the picture mounting assembly. In the illustrated embodiment, the mounting cleat 1320 of the wall mounting member 1300 and the frame cleat 1120 of the frame sections 1110 define complementary angled surfaces configured to engage at an angle of approximately forty-five degrees relative to the wall surface. The angled engagement allows the frame assembly 1100 to be supported on the wall mounting member 1300 by gravity-biased seating of the complementary cleat surfaces. This configuration provides secure engagement while reducing material usage and overall thickness of the frame assembly, making the forty-five degree cleat interface particularly suitable for smaller or lighter planar substrates. The frame assembly 1100 remains removably supported on the wall mounting member 1300, permitting installation, removal, and reorientation while maintaining consistent alignment and load distribution.

[0057] Exemplary use of the picture mounting assembly 1000 includes selecting appropriate frame sections and assembling them to define a perimeter corresponding to the planar substrate. The planar substrate is secured to the frame assembly via the substrate retention surface or adhesive layer. The wall mounting member is attached to the wall using fasteners, optionally aligned using the integrated level. The frame assembly is then engaged with the wall mounting member by aligning and seating the frame cleat with the mounting cleat. Where provided, the locking member is engaged to inhibit unintended disengagement.

[0058] It is therefore submitted that the instant invention has been shown and described in what is considered to be the most practical and preferred embodiments. It is recognized, however, that departures may be made within the scope of the invention and that obvious modifications will occur to a person skilled in the art. With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, system and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

[0059] Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
