Description
- This invention relates generally to the field of wall-mounted ornamental architectural members, and more particularly to such members that are composed of rigid polymer foam material and/or cementitious material, which members incorporate mounting means for attachment to the walls of a building structure.
- Decorative or ornamental architectural pieces, often of intricate or complex design, have long been used to adorn the exterior walls or facades of building such as cathedrals and monuments, and more recently residences and commercial buildings. In early times these architectural members were typically composed of carved stone, concrete, cement, plaster or similar relatively dense and heavy materials. Mounting such heavy pieces onto the walls of buildings composed of similar material presented challenges that could be suitably met. But modern building are usually constructed of materials such as wood, plywood, stucco or the like, which presents new problems relative to architectural ornamentation since securing heavy architectural members to such walls requires new mounting means and techniques. Not only must the architectural pieces remain secure for many years in average environmental conditions, they must be mounted in such manner so as to withstand high winds form hurricanes and the like. With the development of new construction materials, and in particular with the development of rigid expanded polymer foams, the problems have been addressed by manufacturing the architectural pieces out of the rigid expanded polymer foam. These pieces are relatively lightweight, and the pieces can be easily molded and/or cut into intricate shapes and designs. Typically, the planar backs of the architectural pieces are glued directly to the wall using a suitable adhesive, such as an expanding foam adhesive, or the pieces are mounted using mechanical fasteners and mounting brackets glued or fastened to the rigid expanded foam.
- It is often desirable to provide the rigid foam architectural pieces with a cementitious coating, e.g., stucco or the like, or a thick polymer coating, such that the pieces are more durable and to give the appearance of the pieces having been formed from stone or the like. This coating, which may range from ¼ to ⅜ inches in thickness, may be applied by brushing, spraying, dipping or similar manner, and the coating operation is performed at the manufacturing plant, on site or even after the pieces have been mounted on the building. Because several layers of cementitious material are often applied to the rigid expanded foam, the weight of the architectural members is significantly increased. Because of this added weight, mounting means comprising an adhesive and/or simple mechanical fasteners are not suitable in the long term, since the added weight will often result in separation of the pieces from the wall.
- It is an object of this invention to provide a wall-mounted ornamental architectural member, system and mounting methodology that addresses the problems set forth above, whereby the architectural member is formed of lightweight, rigid, expanded polymer foam. It is an object to provide such a member and system where the member is mounted to the building wall in successive steps, whereby each step is easily and readily accomplished in a simple and straightforward manner. It is an object to provide such a member and system where the durability and security of the mount is improved relative to the standard mounting means and methods.
- The invention is in general a wall-mounted architectural member, mounting system and mounting methodology, wherein the architectural member comprises a decorative body composed of lightweight, rigid, expanded polymer foam, such as a polystyrene foam for example, which may be externally coated with a surface cover or skin layer of polymer or cementitious material, such as stucco or cement for example. In a preferred embodiment, the architectural member is manufactured with an extrusion process, such that the decorative body is generally longitudinally extended whereby multiple members may be aligned end-to-end to define horizontal or vertical ornamental elements. However, it is also contemplated that the architectural member may comprise a discrete member formed and mounted individually on a wall surface. On the rear of the architectural body is provided a bracket recess, preferably longitudinally co-extensive with the decorative body. Alternatively, the bracket recess may be provided at spaced locations along the decorative body. The bracket recess extends into the interior of the decorative body and may be formed during the extrusion process or cut into the decorative body after the polymer foam has cured.
- The invention further comprises a mounting bracket having a configuration corresponding in main part with the bracket recess formed in the decorative body, such that the decorative body mates with the mounting bracket. The mounting bracket may be formed of sheet metal, plastic or material of similar properties, and is provided with a wall flange or similar means to receive mechanical fasteners to join the mounting bracket to a building wall. The mounting bracket may be longitudinally co-extensive with the decorative body, or multiple brackets may be provided at spaced intervals. The mounting bracket comprises apertured wall members that extend outwardly from the building wall and into the bracket recess of the decorative body, the wall members defining an interior cavity to receive an expanding foam adhesive.
- The mounting bracket and decorative body are further provided with mating press-fit or snap-fit mechanical interlocking or clip means to temporarily retain the decorative body on the mounting bracket. The mechanical interlocking means preferably comprises a longitudinally extensive retention recess disposed in the decorative body, the retention recess comprising shoulders that define a relatively narrow slot to receive an expanded detention member located on said mounting bracket.
- To mount the architectural member to the building wall, the mounting bracket is fastened to the wall at the appropriate location utilizing mechanical fasteners. An amount of expanding adhesive foam is injected into the bracket recess and/or the interior cavity of the mounting bracket, the amount being sufficient such that upon expansion a quantity of the adhesive passes through the apertures in the walls of the mounting bracket to secure the decorative body thereto, the decorative body having been pressed onto the mounting bracket immediately subsequent to the deposit of the expanding adhesive. The mechanical interlocking means serve to retain the decorative body in place on the mounting bracket during the adhesive curing process.

On the rear of thedecorative body 11 is provided a bracket recess 13, preferably longitudinally co-extensive with thedecorative body 11. Alternatively, one or moreindividual bracket recesses 13 may be provided at spaced locations along thedecorative body 11. The bracket recess 13 comprisesrecess walls 14 and extends into the interior of thedecorative body 11, and may be formed during the extrusion process or cut into thedecorative body 11 after the polymer foam has cured. - The invention further comprises a
mounting bracket 20 adapted for affixation to abuilding wall 99. Themounting bracket 20 is configured so as to generally correspond in main part with the configuration of the bracket recess 13 formed in thedecorative body 11, such that thedecorative body 11 receives and mates with themounting bracket 20. Themounting bracket 20 may be formed of sheet metal, plastic or material of similar properties, and is preferably provided with one ormore wall flanges 21 or similar means to receivemechanical fasteners 22, such as nails or screws for example, to join themounting bracket 20 to thebuilding wall 99. Themechanical fasteners 22 may be disposed infastener apertures 23 positioned in thewall flanges 21. Themounting bracket 20 may be longitudinally co-extensive with thedecorative body 11, ormultiple mounting brackets 20 may be provided at spaced intervals along thebuilding wall 99. Themounting bracket 20 further comprises one ormore wall members 24 that extend outwardly from thebuilding wall 99 and into the bracket recess 13 of thedecorative body 11, thewall members 24 defining aninterior cavity 25 to receive an expandingfoam adhesive 30. Preferably, theinterior cavity 25 of themounting bracket 20 is open to the rear such that the expanding adhesive 30 can contact and bond with the surface of thebuilding wall 99 if sufficient quantity of adhesive 30 is provided. Thewall members 24 of the mounting bracket are provided withapertures 26 in the form of slots, holes, etc., such that the expanding adhesive 30 may pass through thewall apertures 26 to anchor thedecorative body 11 to themounting bracket 20 in addition to forming a thin adhesive bonding layer on portions of the junction between therecess walls 14 and the exterior of themounting bracket walls 24. As shown in the figures, a suitable cross-sectional configuration for the bracket recess 13 and mountingbracket wall members 24 is generally triangular, but it is to be understood that other configurations may be utilized to accomplish the desired purpose. - As shown in
FIG. 4 , therecess walls 14 may be provided withanchor cavities 15 positioned so as to correspond with thewall apertures 26 of themounting bracket 20, theanchor cavities 15 providing additional surface area for bonding of the expandingadhesive foam 30 with the rigid cured foam of thedecorative body 11. Theanchor cavities 15 may be longitudinally coextensive with thedecorative body 11 or positioned at spaced locations, and may be configured so as to have broader internal dimensions such that a mechanical interlock is created upon curing of theadhesive 30. - The
mounting bracket 20 anddecorative body 11 are further provided with mating press-fit or snap-fit mechanical interlocking or clip means 40 to temporarily retain thedecorative body 11 on themounting bracket 20 during the curing of the expandingadhesive 30. Many structure combinations can be used, but in a preferred embodiment the mechanical interlocking means 40 comprises a longitudinallyextensive retention recess 41 disposed in thedecorative body 11, theretention recess 41 comprising shoulders orlips 42 that define a relativelynarrow slot 43 to receive an expanded head ordetention member 44 located on the forward side of themounting bracket 20. As shown in the drawings, a suitable mating configuration for the mechanical interlocking clip means 40 is to configure theretention recess 14 as a longitudinal bore having alongitudinal slot 43, the height of theslot 43 being less than the diameter of the bore, such that a pair oflongitudinal shoulders 42 are defined. Thedetention member 44 of themounting bracket 44 is configured as a circular in cross-section tube connected to the mountingbracket wall members 24 to define aneck 45 of reduced dimension, the outer diameter of thedetention member 44 being equal to the diameter of theretention recess 41 and themounting bracket neck 45 being equal in dimension to theslot 43. Preferably, thedetention member 44 is also provided withapertures 26. In a less preferred embodiment, it is contemplated that thedecorative body 11 can be provided with a male portion and themounting bracket 20 provided with a female counterpart to receive the male portion is a clipping manner. - To mount the
architectural member 10 to thebuilding wall 99, themounting bracket 20 is fastened to thewall 99 at the appropriate location utilizingmechanical fasteners 22. An amount of expandingadhesive foam 30 is deposited in thebracket recess 13 of the decorative body, and additionally or alternatively in theinternal cavity 25 of the mountingbracket 20, the amount being sufficient such that upon expansion a sufficient quantity of the adhesive 30 passes through theapertures 26 in thewalls 24 anddetention member 44 of the mountingbracket 20 so as to bond internally with thewalls 24 of the mountingbracket 20, thedecorative body 11 having been pressed onto the mountingbracket 20 immediately subsequent to the deposit of the expandingadhesive 30. As thedecorative body 11 is pressed onto the mountingbracket 20 prior to full expansion of the adhesive 30, thedetention member 44 of the mountingbracket 20 temporarily compresses theshoulders 42 of theretention recess 41, allowing passage of thedetention member 44 into theretention recess 41, after which theshoulders 42 rebound to retain or lock thedetention member 44 within theretention recess 41 such that thedecorative body 11 is retained on thewall 99 independently of the future adhesive bond. The mechanical interlocking means 40 have sufficient tenacity and strength to retain thedecorative body 11 in place on the mountingbracket 20 during the adhesive curing process. After the expandingadhesive 30 has cured, thedecorative body 11 is bonded to the mounting bracket through thewall apertures 26 and, ifenough adhesive 30 has been provided, the adhesive 30 also bonds the mountingbracket 20 to thebuilding wall 99 through the open back of theinterior cavity 25. In this manner, thearchitectural member 10 is secured to thebuilding wall 99 by bothmechanical fasteners 23 and adhesive bonding. Alternatively, thedecorative body 11 may be pressed onto the mountingbracket 20 prior to injection of the expandingadhesive 30 if access to theinterior cavity 25 is possible through the ends of the mountingbracket 20. - It is understood that equivalents and substitutions for certain elements set forth above may be obvious to ht\\those skilled in the art, and therefore the true scope and definition of the invention shall be as set forth in the following claims.
