Description




BACKGROUND OF THE INVENTION




The present invention pertains to shelving and, more particularly, to shelving units for general household and utility use. A variety of shelf structures and shelving assemblies are known in the art. Many shelving assemblies are provided as “knock down” kits for assembly by the user at a location where the shelving assembly is to be used. This minimizes shipping costs by avoiding the need to transport bulky shelving assemblies. Such knock down shelving assemblies typically include a plurality of generally planar shelves separated by poles connected to the corners of the shelves. The interconnecting components are usually inexpensive and are typically made of a light weight polymeric material, such as molded polypropylene, to further reduce manufacturing and shipping costs.




Most knock down shelving assemblies are intended for use as stand alone units and, in general, they are sufficiently strong and stable for their intended purposes, despite their light weight construction. However, the light weight construction increases the propensity for tipping when improperly loaded. For example, the unbalanced load of a child climbing on one side of the shelving unit may cause the entire unit, and all things stored thereon, to tip over onto the child.




To reduce the likelihood of such dangers, various support brackets have been devised for securing shelves to adjacent walls. In general, such prior art brackets are secured to a wall in a selected location where the shelving unit is to be used. The shelving unit is moved into place and then connected to the pre-mounted bracket. While this is generally effective in preventing tipping of the shelving unit, mounting such brackets in a proper location on the wall before the shelving unit is moved into place can be difficult. Moreover, such brackets are typically designed for connection to particular portions of the shelving unit and are fixed relative thereto once connected. Therefore, although the user may have a particular location in mind for the shelving unit, the precise location may be dictated, at least in part, by the location of wall studs to which to brackets may be mounted.




Thus, there is a need for a shelving unit having mounting brackets or “anchors” that are connectable to the unit prior to being secured to a wall, and which are adjustable relative the shelf once connected to permit precise positioning of the anchor relative to the wall.




SUMMARY OF THE INVENTION




It is a general object of the present invention to provide a shelving unit including a shelf anchor configured for securing the shelving unit to an adjacent wall to prevent tipping. A more specific object of the invention is to provide a shelving unit having a mounting anchor that is connectable to the shelving unit prior to being secured to a wall, and which is adjustable relative the shelving unit after being connected thereto.




In general, a shelving unit of the present invention comprises a shelf and a shelf anchor for securing the shelf to an adjacent wall. The shelf has a generally vertical peripheral rim. The shelf anchor includes a base and a shelf retainer. The base has opposite front and rear sides. The rear side of the base has a wall-engaging portion adapted for flush engagement with the wall. The shelf retainer has a bridge portion and a shelf-retaining portion. The bridge portion extends outwardly from the front side of the base. The shelf-retaining portion extends generally vertically from a distal end of the bridge portion. The shelf-retaining portion is spaced from the front side of the base to define a rim-receiving recess between the front side of the base and the shelf-retaining portion. The shelf retainer is positioned relative to the shelf so that at least a portion of the peripheral rim of the shelf is received within the rim-receiving recess. The rim is received within the recess in a manner to prevent the shelf from moving outwardly from the wall when the shelf anchor is mounted to the wall.




In another aspect of the invention, a shelf anchor comprises a base and a shelf retainer. The base has opposite front and rear sides. The rear side of the base has a wall-engaging portion adapted for flush engagement with a wall. The shelf retainer extends from the front side of the base portion. The shelf retainer has a generally rearwardly facing surface adapted for engagement with a generally forwardly facing surface of the shelf. The rearwardly facing surface of the shelf retainer and the generally forwardly facing surface of the shelf are adapted to engage one another in a manner to prevent the shelf from moving outwardly from the wall when the shelf anchor is mounted to the wall.




The present invention also includes a method for securing a shelving unit to a wall. The method comprises the steps of: providing a shelf anchor having a rim-receiving recess adapted to receive at least a portion of a peripheral rim of one shelf of the shelving unit; positioning the shelf anchor on the peripheral rim of the shelf so that at least a portion of the peripheral rim is received within the rim-receiving recess; and securing the shelf anchor to the wall.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




A shelf anchor of the present invention is shown in detail in

FIGS. 1 through 7

, and is represented generally by the reference numeral


20


. In general, the shelf anchor


20


comprises a base


22


and a shelf retainer


24


. The base


22


has a front side


26


and an opposite rear side


28


. The rear side


28


of the base


22


has a wall-engaging portion


30


adapted for flush engagement with a wall (not shown). As best shown in

FIG. 2

, the shelf anchor is preferably molded as a monolithic hollow piece, to reduce material costs and overall weight of the shelving unit. However, the shelf anchor could comprise multiple pieces or could be made as a solid structure without departing from the scope of the present invention. Preferably, the shelf anchor is molded of a suitable polymeric material, such as polypropylene, but other materials could be used and other manufacturing methods could be employed without departing from the scope of the present invention.




In the hollow configuration of the preferred embodiment of the shelf anchor


20


shown in

FIGS. 2 and 4

, the wall-engaging portion


30


of the anchor


20


is in the form of a relatively narrow, generally rectangular rim. In most cases, the shelf anchor


20


be will be mounted to a flat wall, so preferably, the entire wall-engaging portion


30


lies in a single plane.




The shelf retainer


24


has a bridge portion


36


and a shelf-retaining portion


38


. As best shown in

FIGS. 1 and 5

, the bridge portion


36


extends outwardly and generally horizontally from the front side


26


of the base


22


. The shelf-retaining portion


38


extends generally vertically from a distal end of the bridge portion


36


so that a generally rearwardly facing surface


40


of the shelf-retaining portion


38


is spaced from the front side


26


of the base


22


. As shown in the Figures, the shelf-retaining portion


38


preferably extends generally downwardly from the distal end of the bridge portion


36


to define a recess


42


between the rearwardly facing surface


40


of the shelf-retaining portion


38


and the front side


26


of the base


22


. The importance of the recess


40


is explained below.




As shown in

FIGS. 2

,


4


and


10


, the hollow shelf anchor of the preferred embodiment preferably includes a pair of bosses


46


and


48


, which define holes


50


and


52


adapted to receive mechanical fasteners


56


(see

FIGS. 8

,


9


and


11


) for securing the anchor


20


to a wall (not shown).




A shelf used with the present invention is shown in

FIGS. 8 through 11

, and is represented generally by the reference numeral


60


. In general, the shelf


60


comprises a generally horizontal load supporting surface


62


and a vertical peripheral wall


64


. Post-receiving cylinders


66


are provided at corners of the shelf


60


for receiving shelf-supporting posts (not shown). Preferably, an upper portion of the vertical peripheral wall


64


defines a generally vertical peripheral rim


70


of the shelf


60


, which extends upwardly from the load supporting surface


62


. Preferably, the shelf


60


is also molded of a polymeric material, such as polypropylene, but other materials could be used and other manufacturing methods could be employed without departing from the scope of the present invention.




As shown in

FIGS. 8

,


10


and


11


, the rim-receiving recess


42


is sized to receive at least an upper portion of the vertical peripheral rim


70


of the shelf


60


therein. The vertical peripheral rim


70


of the shelf


60


includes a generally forwardly facing surface


72


, which is adapted for engagement with the rearwardly facing surface


40


of the shelf-retaining portion


38


of the shelf anchor


20


, when the shelf anchor


20


is connected to the shelf


60


as shown in

FIGS. 8

,


10


and


11


. Thus, when the shelf anchor


20


is secured to a wall (not shown) and the peripheral rim


70


of the shelf


60


is received within the recess


42


, the forwardly facing surface


72


of the rim


70


engages against the rearwardly facing surface


40


of the shelf-retaining portion


38


of the shelf anchor


20


to prevent the shelf


60


from moving outwardly away from the wall.




To this point, the preferred embodiment of the shelf anchor


20


has been described as having a shelf retaining portion


38


that extends generally downwardly to define a downwardly facing recess


42


adapted to receive a portion of the peripheral rim


70


upwardly therein. However, alternatively, the anchor could be constructed with a shelf retaining portion that extends generally upwardly to define an upwardly facing recess for receiving a peripheral wall or rim downwardly therein.




Preferably, the recess


42


comprises a channel that extends generally transversely of the front side


26


of the base


22


and generally parallel to the wall when the shelf anchor


20


is mounted to the wall to permit transverse sliding movement of the shelf anchor


20


relative to the peripheral rim


70


of the shelf


60


when the rim


70


is received within the recess


42


. Thus, the shelf anchor


20


is slidable transversely along the length of rim


70


, with the rearwardly facing surface


40


of the shelf retaining portion


38


in sliding engagement with the forwardly facing surface


72


of the rim


70


. This permits precise lateral positioning of the shelf anchor


20


relative to the shelf


60


and relative to the wall after the anchor


20


has been connected the shelf


60


. This is beneficial because, once the shelving unit has been positioned against a wall, the anchors


20


can be moved laterally along the rim


70


of the shelf


60


, e.g., for alignment with wall studs, without the need to move the entire shelving unit.




As shown in

FIGS. 9 and 11

, the vertical peripheral wall


64


of the shelf


60


preferably includes a transverse slot


80


or other aperture adapted for receiving one of the mechanical fasteners


56


therethrough. By fastening the shelf anchor


20


to the shelf


60


with a mechanical fastener


56


passing through the slot


80


, the position of the shelf anchor


20


can be fixed relative to the rim


70


, after the shelf anchor has been moved to a desired location on the rim


70


.




The present invention also includes a novel method of securing a shelving unit of the type described above to a wall, where the shelving unit includes at least one shelf having a peripheral rim. In general, the method comprises the steps of: providing a shelf anchor having a rim-receiving recess adapted to receive at least a portion of the peripheral rim of the shelf; positioning the shelf anchor on the peripheral rim of the shelf so that at least a portion of the peripheral rim is received within the rim-receiving recess; and securing the shelf anchor to the wall. Preferably, the step of securing the shelf anchor to the wall is performed after the step of positioning the shelf anchor on the peripheral rim of the shelf. Also, preferably, the step of securing the shelf anchor to the wall includes sliding the shelf anchor transversely along the peripheral rim of the shelf to a selected location. Again, this is beneficial because, once the shelving unit has been positioned against a wall, the anchors


20


can be moved laterally along the rim


70


of the shelf


60


, e.g., for alignment with wall studs, without the need to move the entire shelving unit.
