Title: Wall anchoring assemblies for heavy objects

Description:
BACKGROUND 
     Numerous products and devices exist for installing a hook or hanging device in a wall, such as for hanging a picture frame, a mirror, or the like. Conventional nails and screws are not always convenient solutions and may not provide sufficient support strength in the wall, particularly in the case of drywall, or other friable wallboards, which are relatively weak. Other hanging devices may avoid the use and attendant drawbacks of conventional fasteners, but nonetheless may result in excessive damage to the wallboard, require the use of conventional tools, or fail to consistent hold the desired weight. 
     SUMMARY 
     The present inventors discovered that both installation and stability of wall hanging system may be considerably improved by relying on systems consisting of independent, cooperating components. The wall anchor assemblies of the present disclosure include a frame and a distinct insert plate. The frame includes one or more prongs that can be inserted into wallboard using light to moderate finger pressure. The insert plate is received in a recess or other guide on or defined by the frame. The insert plate includes a load bearing structure that allows for mounting of myriad objects. Use of a distinct frame renders the prongs easier to insert into the wallboard, while the insert can provide adjustability to the location and orientation of the object to be mounted. The insert can also be disengaged from the frame prior to removal of the assembly from the wall surface, easing removal of the prongs from the wallboard or other wall material. The present disclosure thus provides a wall anchor that can be easily applied manually on drywall and causes reduced or minimal damage upon removal. The assemblies herein can provide a faster and easier way of hanging a heavy weight object, such as large picture frames and mirrors over 25 or 50 pounds. 
     In one aspect, the present disclosure provides a wall anchor assembly for attaching to a mounting surface. The assembly comprises a frame plate having a front surface and a back surface; the frame plate including a recess; a first prong extending outwardly from the back surface of the frame; and an insert receivable within the recess, the insert including a load bearing structure extending a least partially in the opposite direction of the prong. 
     In another aspect, the present disclosure provides a wall anchor assembly for attaching to a mounting surface. The assembly comprises an insert plate having a front surface and an opposing back surface and defining a perimeter, the back surface including an adhesive construction; a frame dimensioned to surround the perimeter of the base plate, wherein the frame includes a recess, and wherein a portion of the insert plate is dimensioned to fit within the recess. 
     As used herein, “layer” means a single stratum that may be continuous or discontinuous over a surface. 
     As used herein “geometry” refers to the size and shape of an element. 
     The words “preferred” and “preferably” refer to embodiments of the disclosure that may afford certain benefits, under certain circumstances. However, other embodiments may also be preferred, under the same or other circumstances. Furthermore, the recitation of one or more preferred embodiments does not imply that other embodiments are not useful, and is not intended to exclude other embodiments from the scope of the disclosure. 
     In this application, terms such as “a”, “an”, and “the” are not intended to refer to only a singular entity, but include the general class of which a specific example may be used for illustration. The terms “a”, “an”, and “the” are used interchangeably with the term “at least one”. The phrases “at least one of” and “comprises at least one of” followed by a list refers to any one of the items in the list and any combination of two or more items in the list. 
     As used herein, the term “or” is generally employed in its usual sense including “and/or” unless the content clearly dictates otherwise. 
     The term “and/or” means one or all of the listed elements or a combination of any two or more of the listed elements. 
     Also herein, all numbers are assumed to be modified by the term “about” and preferably by the term “exactly”. As used herein in connection with a measured quantity, the term “about” refers to that variation in the measured quantity as would be expected by the skilled artisan making the measurement and exercising a level of care commensurate with the objective of the measurement and the precision of the measuring equipment used. 
     Also herein, the recitations of numerical ranges by endpoints include all numbers subsumed within that range as well as the endpoints (e.g., 1 to 5 includes 1, 1.5, 2, 2.75, 3, 3.80, 4, 5, etc.). 
     As used herein as a modifier to a property or attribute, the term “generally”, unless otherwise specifically defined, means that the property or attribute would be readily recognizable by a person of ordinary skill but without requiring absolute precision or a perfect match (e.g., within +/−20% for quantifiable properties). The term “substantially”, unless otherwise specifically defined, means to a high degree of approximation (e.g., within +/−10% for quantifiable properties) but again without requiring absolute precision or a perfect match. Terms such as same, equal, uniform, constant, strictly, and the like, are understood to be within the usual tolerances or measuring error applicable to the particular circumstance rather than requiring absolute precision or a perfect match. 
     The above summary of the present disclosure is not intended to describe each disclosed embodiment or every implementation of the present disclosure. The description that follows more particularly exemplifies illustrative embodiments. In several places throughout the application, guidance is provided through lists of examples, which examples can be used in various combinations.

     DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS 
     While the above-identified figures set forth several embodiments of the disclosure other embodiments are also contemplated, as noted in the description. In all cases, this disclosure presents the invention by way of representation and not limitation. It should be understood that numerous other modifications and embodiments can be devised by those skilled in the art, which fall within the scope and spirit of the principles of the invention. 
     A wall anchor assembly  100  according to one embodiment of the present disclosure is depicted in  FIGS. 1-6 . The wall anchor  100  includes a frame plate  110  and a moveable insert  150  received in a recess  130  defined in the frame  110 . When assembled and as depicted in  FIG. 3 , the anchor  100  presents a generally rectangular shape. The frame  110  includes a front surface  111  opposing a back, wall-facing surface  112 , a top edge  113 , a bottom edge  114 , and opposing side edges  115 ,  116  connecting the top and bottom edges  113 ,  114  to define an outer frame perimeter. A pair of prongs  160  extend outwardly from the top edge  113  at an angle  161  with respect to the back surface  112  (e.g., see  FIG. 3 ). The prongs  160  extend to an outer end  162  that can be tapered to ease insertion when pressed into wall board. 
     The frame  110  has an overall, generally “U”-shaped configuration, though other configurations such as “V”-shaped or “C”-shaped are possible. The frame  110  includes a first section  120  and a second section  122  that is opposed to the first section  120 . The first section  120  and the second section  122  extend in generally parallel directions. The first section  120  is spaced apart from the second section  122  to present an open-ended region or recess  130  for receiving the insert  150 . The recess  130  generally corresponds in at least the width dimension to the width of the insert  150 . The frame  110  further includes a third section  124  that interconnects the first section  120  and the second section  122 ; the sections  120 ,  122 , and  124  are typically coplanar and include front surfaces residing in a plane “P”. 
     As depicted in  FIGS. 1-6 , the recess  130  is generally rectangular when viewed in a plane perpendicular to the frame plane “P”. In alternative embodiments, however, the recess may take on another shape or shapes, including circular, ovular, triangular tetrahedral, Y-shaped, etc. Though the recess  130  is depicted as generally matching the shape of the anchor  100  as assembled (e.g.,  FIG. 3 ), this correspondence is not necessary. For instance, the recess  130  may include an ovular shape when viewed in a plane perpendicular to the frame plane “P”, while the anchor  100  presents an overall rectangular shape. Other variations are contemplated and discernable by those of skill in the art. 
     A guide  140  surrounds the periphery of the recess  130  and includes opposing rails  142  integral with the first and second sections  120 ,  122 , and third rail  148  extending along the bottom of the recess  130  on the third section  124 . The rails  142  are coupled to the respective section of the frame via a guidewall  144 , which is arranged substantially perpendicular to the frame plane “P”. Each rail  142  is spaced from the frame plane “P” according to the height of the guidewall  144 , which generally corresponds to a thickness of the insert  150 . 
     The rails  142  serve to accept and guide the insert into the bottom of the recess, while the bottom rail  148  acts a stop surface or detent to arrest sliding of the insert  150  in the direction of the bottom edge  114 . As depicted, each rail  142  extends the full length of the recess  130  to the top edge  113  of the frame, while the bottom rail  148  extends the full width thereof. In other embodiments, any or all rails may extend only a portion of the recess dimensions; in particular, the third rail  148  may be centrally located on the third section, and may not connect to either or both the side rails  142 . 
     The rails  142  and  148  extend over and into the recess  130 , forming an overlay surface  145  facing the frame plane “P”. The overlay surface  145  limits or prevents rotational movement of the insert  150  about an axis coincident with a loading bearing projection  170  when the anchor is assembled, as well as operating to aid the placement of the insert  150  within the recess  130 . As one skilled in the art can appreciate, there may be appropriate tolerances between the rails  142  and the dimensions of the insert to facilitate sliding of the insert  150  and avoid binding The spacing of the overlay surfaces  145  also allows a front surface  151  of the insert  150  to reside in or directly adjacent the frame plane “P”, allowing the back surface  112  of the frame to remain generally flush with the wall. 
     Both the first and second frame sections  120 ,  122  include a prong  160  coincident with the upper edge  113  and respective side edges  115 ,  116  of the frame  110 . The prongs  160  extend to an outer end point  162  over a length that is generally equal to or less than the thickness of the wallboard to which the anchor would typically be attached. The lengths of the prongs can be varied to allow selection for a specific thickness of wallboard. 
     As previously described, the prong  160  forms an angle  161  with the back surface  112  of the frame. By way of example, angle  161  (e.g., taken relative to a plane parallel to the frame plane “P”) may be between about 75 degrees and about 90 degrees (such as between about 80 degrees and about 90 degrees or between about 85 degrees and about 90 degrees), though variations are possible. In presently preferred implementations, the prongs  160  extend generally along a plane that is substantially orthogonal to the frame plane “P”. Without wishing to be bound by theory, providing an excessively acute between the prong  160  and the back surface  115  tends to shear gypsum wall board. A slightly acute angle (e.g., an angle  161  of  80  degrees or greater), however, may ease insertion of the anchor  100  and assist in drawing both the frame  110  and insert  150  substantially parallel to the wall board in certain embodiments. 
     The prongs  160  may include one or more flat surfaces and may comprise different cross-sectional shapes and combination of shapes (e.g., rectangular, circular, ovular, triangular etc.). For instance, an upper surface of a prong may be rounded, with a planar bottom surface to prevent crack propagation in the wallboard. The prongs  160  can taper over all or a portion of the length between the back surface  112  and the outer end  162 . In the illustrated embodiment, and as can be seen particularly clearly from  FIGS. 1, 2, and 5 , the prongs  160  can be formed from a monolithic piece of material that has been bent or otherwise articulated to form both frame sections  120 ,  122  and prongs  160 . Thus, the prongs  160  include at least one section that is integral and coplanar with the top edge  113  of the frame  110 . In other embodiments, the prongs may be soldered, welded, or otherwise attached to the back surface  112  of the frame  110  at an edge or other location spaced from the recess  130 . 
     Like the frame  110 , the insert  150  includes the front surface  151  opposing a back, wall-facing surface  152 , a top edge  153 , a bottom edge  154 , and opposing side edges  155 ,  156  connecting the top and bottom edges  153 ,  154  to define an outer insert perimeter. The insert  150  further includes a thickness  157  that generally corresponds to the height of the guide walls  144 , at least in areas proximate the side edges  155 ,  156 . As depicted in  FIGS. 1-6 , the insert  150  is generally rectangular when viewed in a plane perpendicular to the frame plane “P”. In alternative embodiments, however, the insert  150  may take on another shape or combination of shapes, including circular, ovular, triangular, tetrahedral, Y-shaped, etc. Though the insert  150  is depicted as generally matching the shape of the anchor  100  and the recess  130 , such correspondence is not strictly necessary. 
     A load bearing projection  170  extends outward from the front surface  151  of the insert  150 . The load bearing projection  170  is depicted as including a shaft  172  and cap  174 , similar to that of a conventional nail. The insert  150  may instead feature a hook, a ledge, a shank, or any number of load bearing structures used to hang articles. In other embodiments, the front face of the insert may feature a layer of adhesive (described in further detail below). The projection  170  is disposed proximate the bottom edge  154  of the insert  150  in the depicted embodiment. It should be appreciated, however, that the projection  170  may be placed at any desired location on the front face  151 , though typically such that it resides generally below the prong end  162  when the anchor  100  is assembled. 
     The anchor may be installed on a wallboard  190  (see  FIG. 4 ) in assembled or disassembled form. In one exemplary method of hanging an object using the anchor assembly  100 , the frame  110  is provided without the insert  150  received in the recess  130 . The frame  110  is positioned at the desired location of the wall, and the user provides a generally horizontal force to front face  111  of opposing frame sections  120 ,  122  to drive the prongs  160  into the wallboard. The object to be hung is secured on the load bearing projection  170  (or otherwise adhered to the front  151  of the insert  150 ), and the insert is then slidably engaged with the recess  130 . Alternatively, the object may be secured on the load bearing projection  170  after the insert  150  has been placed in the recess. To remove the anchor  100  from the wall, the user may remove the insert  150 , and the use the bottom rail  148  to pull the frame  110  and prongs away from the wall surface. 
     As can be appreciated, the use of a multi-part anchor  100  allows the object to be easily removed from the wall without affecting the frame  110  or potentially damaging the wallboard. Accordingly, a user may also easily adjust the position of the insert relative to the object, allowing for fine adjustment in object location and orientation. 
     The anchor assembly  100  may be provided as a kit including a frame  110  and a plurality of inserts  150 . The inserts  150  may vary in location and character (e.g., hook, shank, nail, decorative element) of the load bearing projection, or may vary in material composition. In another kit of the present disclosure, a plurality of frames may be provided with a plurality of inserts. The plurality of frames may vary amongst multiple characteristics including but not limited to recesses geometry, frame geometry, and prong geometry. Each of the plurality of frames may be adaptable for use with one or more of the plurality of inserts. In this way, the anchor  100  may serve as a universal mounting apparatus for a variety of objects. 
     In presently preferred implementations, the frame  110  and the insert  150  are made of a metal material, however, it can be appreciated that other suitable materials can be used. Each of the frame  110  and insert  150  are typically made from a resilient metal or metal alloy, such as stainless steel, titanium, cobalt-chromium alloy (such as manufactured by Elgiloy Specialty Metals, Elgin, Ill.), or a shape-memory alloy such as an alloy of nickel and titanium (e.g., Nitinol). Preferably, the frame  110  and insert  150  are sufficiently resilient so that the shape of the frame  110  and insert  150  when relaxed does not significantly change during the course of mounting an object. As another option, the frame  110  and insert  150  could be made from any other resilient material known to one skilled in the art, such as a flexible polymer or composite material. Moreover, although the anchor assembly  100  is specifically discussed as mountable on a wall of gypsum wallboard, it can be utilized with walls of other materials or to secure an object to something other than a wall. 
     Turning to  FIGS. 7-10 , another embodiment of a wall anchor assembly  200  according to the present disclosure is depicted. Wall anchor  200  includes a frame  210  and an insert  250 . The frame  210  includes a guide  240  including opposing rails  242  to form a recess  230 . The recess  230  includes a continuous back plate  234 , such that a portion of the frame  210  is disposed between the insert  250  and wall when the anchor  200  is assembled. The insert  250  includes a load bearing projection  270  and is dimensioned to slidably engage the guide  240 . It is to be understood that many other aspects of anchor  200  may have similar form and function to those described with respect to anchor  100  and these need not be repeated. 
     The frame  210  includes an upper section  220  pivotally joined to a lower section  222  by a hinge segment  226 . The hinge segment  226  allows for the upper section  220  to rotate relative to the lower section  222 , and vice versa. The hinge segment  226  may be created by a single hinge pin extending some portion or all of the width of the frame, or a may be formed from a flexible segment of material. In presently preferred implementations, the hinge segment  226  is located proximate the middle of the frame  210 . It is also contemplated that the frame  210  can be provided without a hinge segment or other pivotable mechanism. 
     The upper section  220  includes two pairs of spaced apart prongs  260 ,  264 , while the lower section  222  also includes its own pair  266 ,  268 . The prong pairs  260  and  264  are position adjacent the top and bottom edges of the upper section  220 , respectively, and the prong pairs  266  and  268  are positioned adjacent the top and bottom edges of the lower section  222 . Each prong pair  260 ,  264 ,  266 ,  268  extends outward from the back surface of the respective section at a substantially orthogonal angle. Fewer prongs or prong pairs may also be used with the exemplary anchor  200 , but the plurality of insertion points can improve the stability of the frame  210  during installation, use, and removal. 
     To use anchor  200 , a user selects the desired position on the wall to support an object. Next, pressure is applied horizontally to the lower section  222 . This pressure forces the prong pairs  266 ,  268  into the wallboard. The pressure is applied continuously until the prongs penetrate the wallboard completely and the lower section  222  is flush with the vertical surface of the wall. 
     While the lower section  222  is held securely to the wall, force is applied in direction orthogonal to the front face  211  of the upper section  222 . The orthogonal force applied results in the upper section  222  rotating around the hinge connection  226  due to the fixed location of the lower section  222 . The rotation of the upper section  222  continues until the outer end of the prong pairs  260 ,  264  penetrate the wallboard. Further rotation results in the remaining length of the prong being driven into the wallboard. The object to be hung is secured on the load bearing projection  270 , and the insert  250  is then slidably engaged with the guide  240  towards the bottom edge  214  of the frame  210 . Alternatively, the object may be secured on the load bearing projection  270  after the insert  250  has been secured in the guide  240 . Full receipt of the insert  250  in the guide  240  prevents further rotation about the hinge segment  226 , thereby guarding against undesired removal of the prongs  260 ,  264  and the potential failure of the wallboard. 
     Yet another embodiment of a wall anchor  300  according to the present disclosure is depicted in  FIGS. 11-16 . The wall anchor  300  includes a frame  310  and an insert plate  350 . The frame  310  further includes a closed recess  330  surrounded by a first frame side section  320 , a second frame side section  322 , a frame top section  326 , and a frame bottom section  328 . The interior edges of the frame sections  320 ,  322 ,  324 , and  326  cooperate to define the perimeter of the recess  330 . The frame includes a front surface  311 , a back surface  312   a  of the top section  324 , and a back surface  312   b  of the bottom section  326 . Both the front  311  and back surfaces  312   a ,  312   b  are substantially planar, with the front surface  311  residing in a frame plane “P” and the back surfaces  312   a ,  312   b  residing in a frame plane “B”. It is to be understood that many other aspects of anchor  300  may have similar form and function to those described with respect to anchors  100  and  200 , and these need not be repeated. 
     Each frame side section  320  and  322  features both a reduced thickness in the direction of the wall (i.e., the z-direction) and a reduced width (i.e., in the x-direction) as compared to frame top section  324  and frame bottom section  326 . The reduced thickness results in a pair of grooves  340  on either side of the recess  330 . The grooves  340  extend at least the length of the recess  330  and include a groove surface  342  residing in a plane parallel to the frame plane “B”. Prongs  360  extend outwardly from the groove surface  342  and are disposed proximate the top section  324 . 
     The insert  350  includes a central region  352  having a load bearing projection  370  and opposing ledges  354  disposed on either side of the central region  352 . The central region  352  is dimensioned to be matingly received in the recess  330 , with a width  353  larger than the width of either ledge  354 . While depicted a having a larger width in the x-direction, it is also contemplated that one or both ledges  353  may be larger in width than the central section, and that the ledges  354  may be oriented above and below the central regions  352 . 
     Each ledge  354  has a reduced thickness in the wall direction compared to the central region  352 , and includes a front surface  355  designed engage a groove surface  342  of the frame  310  when the anchor  300  is assembled. In some embodiments, one or both ledges include a width less than the width of the groove surface  342 , allowing the prongs  360  to straddle the full width of the insert  350 . In other embodiments (not depicted), one or both of the ledges can include a bore or other through-hole positioned to receive one of the pair of prongs  360  on frame  310 . 
     A back surface  356  of the insert  350  can include an adhesive construction for temporarily securing the insert  350  to a wall surface. For example, the back surface may be coupled to a Command™ Adhesive Strip or a Command™ Picture Hanging Strip, both available from 3M Company. In some embodiments, the adhesive construction can include a pressure sensitive adhesive and a backing, while in other embodiments the adhesive construction includes only a continuous or discontinuous layer of pressure sensitive adhesive. A general description of useful pressure sensitive adhesives may be found in the Encyclopedia of Polymer Science and Engineering, Vol. 13, Wiley-Interscience Publishers (New York, 1988). Additional description of useful pressure-sensitive adhesives may be found in the Encyclopedia of Polymer Science and Technology, Vol. 1, Interscience Publishers (New York, 1964). Pressure sensitive adhesive compositions are well known to those of ordinary skill in the art to possess properties including the following: (1) tack, (2) adherence with no more than finger pressure, (3) sufficient ability to hold onto an adherend, and (4) sufficient cohesive strength to be cleanly removable from the adherend. Materials that have been found to function well as pressure sensitive adhesives are polymers designed and formulated to exhibit the requisite viscoelastic properties resulting in a desired balance of tack, peel adhesion, and shear holding power. Suitable PSAs may be based on crosslinked or non-crosslinked (meth)acrylics, rubbers, thermoplastic elastomers, silicones, polyurethanes, and the like, and may include tackifiers in order to provide the desired tac, as well as other additives. In some embodiments, the PSA is based on a (meth)acrylic PSA or at least one poly(meth)acrylate, where (meth)acrylate refers to both acrylate and methacrylate groups. In some embodiments, the PSA is an olefin block copolymer based adhesive. 
     The adhesive construction used on the insert  350  maybe peelable or stretch releasable. In embodiments featuring a stretch releasable construction, the construction can be removed from a surface by stretching it at an angle of less than 35°. In embodiments featuring a peel-releasable construction, the adhesive can be removed from a wall surface by stretching it an angle of 35° or greater. In some embodiments, the releasable adhesive may be removed by a combination of stretch and peel-release mechanisms. 
     An insert  350  featuring one or more stretch release adhesive constructions can include, for example, any of the adhesives and constructions described in any of the following patents: U.S. Pat. No. 5,516,581 (Kreckel et al.); U.S. Pat. No. 6,231,962 (Bries et al.); U.S. Pat. No. 7,078,093 (Sheridan et al.); and U.S. Pat. No. 6,395,389 (Lühmann et al.), all of which are incorporated by reference herein in their entirety. 
     An insert  350  featuring one or more peelable adhesive constructions can include, for example, any of the adhesives and constructions described in any of the following patent applications: International Publication Nos. 2015/035556, 2015/035960, U.S. Pat. No. 9,894,931, and PCT Application Nos. US2017/015163 and US2017/014733, all of which are incorporated herein in their entirety. 
     The adhesive construction may further include one or more release liners. The release liner can be, for example, on either or both of major surfaces of the adhesive layers. The release liner protects the adhesive during manufacturing, transit, and before use. When the user desires to use the adhesive construction, the user can peel or remove the release liner to expose the adhesive. Examples of suitable liners include paper, e.g., kraft paper, or polymeric films, e.g., polyethylene, polypropylene or polyester. 
     The use of a removable adhesive on the insert  350  allows for a user to adjust the position of the insert  350  before committing to the location of the anchor  300  or otherwise puncturing the wall. To use anchor assembly  300 , a user first removes any release liner from the adhesive construction on the insert. The insert  350  is then placed at the desired location and secured to the wall surface using finger pressure in the direction of the wall. Advantageously and depending on, e.g., the shear strength of the adhesive constructions used, the object to mounted may be hung from the load bearing projection at this point to confirm desired location and orientation. Once the user is satisfied with the location of the insert  350 , the frame  310  is placed over the insert  350  so that recess  330  is generally aligned with the central region  352 . Finger pressure in the direction of the wall surface on the side sections  320 ,  322  may be used to drive prongs  360  into the wallboard. The user may apply pressure until the central section  352  is received in the recess  330  and the ledge front surfaces  355  contact the groove surfaces  342 . Contact between the front surface and the groove surface may provide an audible “click”, alerting the user that the anchor  300  is suitably assembled. Once finished, the groove surfaces  342  on the frame  310  provide a rotational stop on the insert  350 , such that a moment created on the insert by an object on the loading bearing projection  370  does not cause the insert  350  to debond from the wall surface. 
     The wall anchors described herein may be used to mount various items and objects to surfaces such as painted drywall, plaster, concrete, glass, ceramic, fiberglass, metal or plastic. Items that can be mounted include, but are not limited to, wall hangings, organizers, holders, baskets, containers, decorations (e.g., holiday decorations), calendars, posters, dispensers, wire clips, guitars, and carrying handles.
