A display rack comprises a frame, at least one dividing base unit and a track. The track supports a follower arrangement. The base unit comprises a partition wall and a support surface. The track is positioned on the support surface and is capable of lateral translation relative to the support surface. The base unit itself is laterally displaceable relative to the frame. The base unit reinforces the track unit against generally vertical bending forces.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention is generally related to display racks. More particularly, the present invention is related to display racks having follower assemblies supported on a track that is laterally repositionable relative to a supporting shelf




2. Description of the Related Art




Shelving assemblies are used to display products in stores of all types. Due to the fierce competition among stores, great efforts are made to maintain a tidy appearance. For instance, many stores employ stock people who constantly reshelve merchandise or rotate merchandise to maintain an orderly appearance of products on the shelves. Paying people to perform such full time restocking can greatly increase overhead costs. Accordingly, stores have begun to use shelving that will urge the products forward such that a fully stocked appearance can be maintained although the shelves are not constantly being restocked.




Some stores have also recognized that reconfiguring the displays increases the time an individual spends in the store shopping. For instance, if products are not shuffled to some degree within a store, an individual that frequents that store proceeds directly to the location of the product they came looking for, picks up that product, pays for the product and leaves the store. On the other hand, by slightly shuffling product location on a periodic basis, the same individual spends more time wandering the aisles or otherwise browsing the product selection. The increase in time often will increase the number of impulse purchases made within the store.




Shelving that urges products forward, however, suffers from at least one major drawback in the shuffling of products. The shelving is difficult to reconfigure in a rapid manner. In addition, various products have different weights and, in some arrangements, the shelving has differing load-bearing capabilities. Thus, moving a large and heavy product to a shelving assembly previously configured for smaller and lighter products may not be possible. Instead, the products and the shelving assemblies would have to be relocated as a unit. This is a time consuming and tedious job.




SUMMARY OF THE INVENTION




Recently, a shelving assembly allowing rapid lateral readjustment has been created. Examples of such adjustable shelving assemblies having follower assemblies are disclosed in copending U.S. patent application Ser. No. 09/518,341, which was filed on Mar. 3, 2000, and co-pending U.S. patent application Ser. No. 09/379,704, which was filed on Aug. 24, 1999, both of which applications are hereby incorporated by reference in their entirety. These shelving assemblies comprise track units that are either integral with, or separately formed of, dividing walls. The track units can be adjusted side to side to increase or decrease the distance between the dividing walls. Thus, larger packages can be readily accommodated.




A drawback to simply adjusting the tracks and the dividers is readily apparent in the combined track and dividing wall configuration. In this configuration, the track, and therefore the follower assembly mounted on the track, are not centrally located between the two adjacent dividing walls. While the failure to centrally position the track and follower assembly may have little consequence in smaller and lighter products, such an off-center arrangement increases the wear rate when used with larger and heavier products. The torque created by the follower assembly can cause rapid system failure in some arrangements.




Similarly, if the track is formed separate of the vertically-extending dividing wall, large loads can cause failures in the track over time. For instance, without the vertically-extending dividing wall, the track is more likely to bow in the center over time if unsupported. The vertically-extending dividing wall stabilizes the attached track and provides reinforcement against vertical bowing. Thus, while separating the track and the dividing wall allows the track to be centralized between the dividing walls, the track can be largely unsupported and more susceptible to bowing and breaking along a central portion of the track.




Accordingly, a need exists for an easily adjusted display system that provides the advantages of forward-feeding display systems that admits of rapid reconfiguration while also allowing a more centralized follower assembly and increased vertical support for improved load-bearing characteristics.




Thus, one aspect of the present invention involves a display rack comprising a frame, a base unit and a track. The base unit comprises a generally vertical dividing wall portion and a generally horizontal support surface portion. The track is disposed on the generally horizontal support surface portion and the track carries a pusher block. The pusher block is capable of translating along the track in a generally longitudinal direction and is biased to a forward direction. The track is capable of translating along the support surface portion of the base unit in a generally lateral direction and the base unit being capable of translating along the frame in a generally lateral direction.




Another aspect of the present invention involves a display rack comprising a front panel, a rear panel spaced from the front panel and at least one divider generally extending between the front panel and the rear panel. The divider comprises a support surface and a partition. The divider is laterally slideable relative to the front panel. A track is laterally slideably positioned on the support surface and the track generally extends between the front panel and the rear panel. The track supports a forward biased pusher block and is connected to at least one of the front panel and the rear panel. The track is generally secured from substantial vertical movement and the track at least partially secures the divider from substantial vertical movement.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




With reference initially to

FIG. 1

, an adjustable display rack for use as a shelf management system, generally designated by reference numeral


10


, is illustrated. The adjustable display rack is configured and arranged to accept packages of various sizes, weights and configurations. For instance, the present adjustable display rack may be commonly used with prepackaged and bagged salads and other types of produce. Additionally, in one embodiment, the present adjustable display rack


10


may have particular utility with pharmaceutical products, such as drugs and vitamins. While certain features, aspects and advantages of the present invention typically are used with comestible products in stores, such as grocery stores and convenience marts, other features, aspects and advantages of the present adjustable display rack may find utility in a variety of other environments, including warehouses, hospitals, drug stores, office supply rooms, auto parts stores and clothing stores, for instance, but without limitation.




With reference to

FIG. 2

, a display rack


10


arranged and configured in accordance with certain features of the present invention generally features a divider


62


that comprises a partition wall


70


and a support surface


72


. The divider


62


preferably is laterally moveable relative to a frame assembly


12


. A track


60


and a follower assembly


14


are supported by at least a portion of the illustrated support surface


72


and are laterally slideably supported on the illustrated support surface


72


between a pair of motion limiting ribs


74


.

FIG. 2

illustrates movement of the track


60


and the associated follower assembly


14


with a broken line reproduction of the components and the broken line arrow showing the movement. Thus, the divider


62


provides increased load-bearing support for the track such that the track


60


can accommodate greater vertical loads. In addition, both the divider


62


and the track


60


in the illustrated arrangement are




The present adjustable display rack


10


is generally comprised of a frame


12


and a follower assembly


14


, which forward-feeds the shelved product. While the illustrated frame


12


may be simply placed upon a shelf or other similar structure, it is contemplated that the frame


12


may be positioned within a slideable drawer (not shown) such that the drawer may be pulled out to provide access to the entire frame


12


where the adjustable display racks


10


are oriented in close vertical relationship to one another. Such a slideable mounting assembly generally would ease product rotation for products positioned within the display rack


10


by allowing the stock person full access to the full dimension of the follower assembly


14


.




With continued reference to

FIG. 1

, the frame


12


generally comprises a first and second end. In the preferred embodiment the first and second end are a front panel


16


and a rear panel


18


. The panels


16


,


18


extend generally parallel to one another at a substantially fixed distance.




With reference now to

FIG. 5

, the illustrated front panel


16


generally comprises an inverted F configuration. Preferably, the front panel


16


comprises an integrally-formed forward-facing channel


20


generally defined by an upper lip


22


and a lower lip


24


. The channel


20


is desirably sized and configured to accommodate sku identifiers or other product identification and pricing information to be positioned proximate to products which may be positioned and displayed in the adjustable display rack


10


.




The front panel


20


also preferably comprises a rearward-facing race


30


. The race


30


in the illustrated arrangement is generally defined by an upper flange


32


and a lower support surface


34


. The race


30


preferably is sized and configured to allow relatively free movement of product tracks and dividers in manners which will be described in greater detail below. It will be recognized that other arrangements also can be used. For instance, the race


30


can be defined by a front panel that snaps downward into a slot extending along a forward edge of a shelf and an upper surface of the shelf itself, such as the constructions disclosed in co-pending U.S. patent application Ser. No. 09/518,341, which was filed on Mar. 3, 2000 and which is hereby incorporated by reference in its entirety.




With continued reference to

FIG. 5

, a product retaining wall


36


desirably extends upward between the forward-facing channel


20


and the race


30


and preferably angles slightly rearward from a location above the upper lip


22


and the upper flange


32


. Of course, other configurations also are possible. For instance, the product retaining wall


36


may be generally vertical or may recline rearward at other locations. The product retaining wall


36


advantageously serves as a forward-most stopping surface for the adjustable display rack


10


and is desirably angled rearward to help pinch and hold product within the adjustable display rack


10


while the product is being urged forward in manners to be described in greater detail below.




The rear panel


18


can have any suitable construction. In some arrangements, the rear panel


18


is configured in a simple C shape. As such, the rear panel


18


would generally comprise an upper flange and a lower support surface, similar to the surfaces defining the race


30


of the front panel


16


.




It should be noted that the lower support surface of the rear panel


18


, as well as the lower support surface


34


of the front panel


16


, desirably extend at greater lengths toward one another than the upper flange of the rear panel


18


and the upper flange


32


of the front panel


16


. The greater extension increases the surface contact area between the lower support surfaces and any base structure, such as a shelf or a drawer, for instance, on which the adjustable display rack


10


rests.




In the illustrated configuration, the lower support surfaces each can receive a magnetized material that forms an additional layer below the lower support surfaces. This magnetic layer may extend the entire length of the front panel


16


and the rear panel


18


or can be segregated into shortened portions serving as feet for the adjustable display rack


10


. In some embodiments, the additional layer may not be necessary, while in other embodiments, the additional layer may comprise rubberized components for shock absorption and the like, as well as hook and loop fasteners or other suitable securing and supporting components. It is anticipated that, in some heavy-duty arrangements, at least a portion of the front panel and/or the rear panel can be formed of a magnetizable material such that an attraction between a shelf and the front panel and/or the rear panel can be built into the construction without the need for an additional layer.




With reference again to

FIGS. 1-3

, the illustrated frame


12


of the rack


10


also generally comprises a first and second side. In the illustrated arrangement, the first and second sides are end pieces


40


,


42


. The end pieces


40


,


42


may be distinct elements or may be portions of the follower assembly


14


which will be discussed in detail below.




The end pieces can be distinct elements or can be formed by the dividers


60


. In either situation, the end pieces preferably are attached to the front panel


16


and the rear panel


18


to form the enclosed frame


12


. The end pieces


40


,


42


more preferably are attached such that one is permanently attached to the front panel


16


and the rear panel


18


while the other is semipermanently attached to the front panel


16


and the rear panel


18


. Any suitable manner of connecting the members can be used. By allowing at least one of the end pieces


40


,


42


to be removed, components can be easily added or removed from the races formed in the front panel


16


and the rear panel


18


. Of course, it is anticipated that the dividers


62


and the tracks


60


also can be snapped in and out of the frame


12


in any suitable configuration.




The illustrated display rack


10


also comprises a plurality of tracks


60


. Any number of tracks


60


can be used. The arrangement of

FIG. 1

features three tracks


60


. The tracks


60


generally underlie the products. As such, each track


60


, at least in part, supports the products as they are moved in a forward direction.




The illustrated track


60


generally extends longitudinally between the front panel


16


and the rear panel


18


. The tracks


60


are disposed laterally between the end pieces


40


,


42


. The illustrated track


60


is supported in manners that will be described below and carries the follower assembly


14


, which will be described in greater detail.




With continued reference to

FIG. 1

, the tracks


60


preferably are positioned between one of the end pieces


40


,


42


and a divider or between a pair of dividers


62


. In some arrangements, the tracks and dividers are integrally formed (i.e., formed of a single piece—see FIG.


5


).




Preferably, however, the tracks


60


and the dividers


62


are separately formed. In these arrangements, the track


60


can be positioned atop of a portion of the divider


62


in a manner that will be described such that the divider can provide increased support to the load bearing track


60


. Moreover, by positioning the track


60


atop a portion of the divider


62


, the display rack


10


features increased flexibility in the sizes of products which may be carried by the product tracks and the dividers. For instance, in such a separated configuration, the track


60


can be centrally positioned between the walls defined by either the end pieces


40


,


42


or the dividers


62


such that decreased twisting of the products is created during forward feeding.




With reference now to

FIG. 3

, the product track


60


and the divider


62


of a preferred arrangement will be described in more detail. An additional construction of the track


60


and the divider


62


, which is substantially the opposite of the arrangement of

FIG. 3

, is illustrated in FIG.


4


. The divider


62


generally comprises a substantially vertically-extending partition wall


70


and a generally horizontally-extending support surface


72


. Preferably, the partition wall


70


and the support surface


72


are disposed at a substantially right angle to each other. In some configurations, however, the two may extend at an angle to each other. For instance, in arrangements supporting rounded articles, such as plates and the like, the partition wall


70


may extend at an obtuse angle relative to the support surface


72


to provide a surface that extends at a tangent to an outer perimeter of the supported product while the track


60


supports a portion of the product. It is also anticipated that a partition wall


70


may be interposed between a pair of support surfaces


72


. For instance, a T-shape may result.




The support surface


72


preferably comprises a number of upstanding ribs


74


,


76


. The intermediate ribs


74


in the illustrated arrangement provide support against bending forces. In addition, the intermediate ribs


74


define a range of motion for the track


60


relative to the support surface


72


. In particular, the ribs


74


, together with a portion of the support surface


72


, define a tray member in which the track


60


is disposed. Preferably, the separation between the ribs


74


(i.e., the width of the tray member) is substantially greater than an outer lateral dimension of the portions of the track


60


that are contained within the tray member. This configuration allows some lateral movement of the track


60


relative to the dividers


62


while also limiting the movement to a manageable range.




The outer rib


76


provides additional support against bending forces. In effect, the rib


76


primarily is a stiffening rib. Of course, in some arrangements, the rib is not formed while in other arrangements, the rib forms a second position for the track such that the track can be positioned between the outer rib


76


and the nearest intermediate rib


74


. In such an arrangement, at least two positions are defined. The track


60


can be positioned in either tray and a limited lateral range of motion is defined for the track


60


in that tray. Additionally, in some configurations used with large or bulky products, multiple tracks


60


can be used such that the number of tracks supporting the products can be increased. In this regard, it is anticipated that the number of trays formed on any single divider


62


can be as few as one or more than two. Furthermore, in some arrangements, an outer rib (i.e., the rib


76


) positioned farthest from the partition wall


70


can be removed and the track


60


can be allowed to translate off of the support base


72


; however, the illustrated arrangement ensures that the track


60


will always be reinforced for vertical loading by the support surface


72


.




The bottom of the illustrated support surface


72


of the divider


62


is substantially smooth. The bottom of the support surface can receive a friction increasing member (i.e., a roughened surface of any sort) to reduce the likelihood of lateral movement when loaded. Of course, in some configurations, movement may be desired and, in such configurations, the bottom surface may receive various treatments that will reduce the contact surface area between the bottom surface and the surface that supports the dividers


62


. It also is envisioned that the divider


62


can be secured against lateral displacement by mechanical fasteners of any sort, including adhesives, epoxies, screws, rivets, brads, clips, pins and the like.




With continued reference to

FIGS. 3 and 4

, the track


60


generally comprises a support base


80


and a set of rails


82


. The support base


80


in the illustrated arrangement preferably is a plate-like member that supports both of the rails


82


. While the rails


82


generally are centrally positioned on the support base


80


, the central location is not necessary and the rails


82


can be offset to one side or the other. Positioning the rails


82


in a central location, however, advantageously reduces the twisting forces that may be generated at the interface between the support base


80


and the support surface


72


. In addition, the support base


80


can comprise a number of upstanding ribs, which are not shown in the illustrated arrangement, to help support the product being dispensed. In such an arrangement, the ribs preferably would extend upward to about the same height as the upper surfaces of the rails


82


and, in a more preferred arrangement, these ribs as well as the ribs


74


,


76


of the divider


62


would all extend to about the same height as the upper surface of the rails


82


.




The interface between the support base


80


and the support surface


72


is generally formed by two smooth surfaces in the illustrated arrangement. It is anticipated, however, that relative movement can be reduced under load if a roughened surface forms at least a portion of the interface. Generally speaking, the products typically are fairly box-like in nature and movement of the track


60


relative to the dividers


62


is not a large issue. Of course, with other types of products, such movement could be an issue and, in such arrangements, the frictional forces can be increased in any suitable manner.




The support base


80


in the illustrated arrangement is largely rectangular. It is anticipated that the support base


80


can have other structures. For instance, the support base can comprise a number of fingers that extend outward in a generally square-wave construction rather that a full rectangle. The rectangular support base


80


is presently preferred, however, because such a configuration maximizes the contact surface area while also maximizing the available range of lateral movement. It is envisioned, however, that triangular fingers, for instance, could extend laterally outward from the rails


82


and extend through gaps in the ribs


74


such that the contact surface area is not substantially reduced but the available range of lateral movement is increased.




With reference now to

FIGS. 6 and 7

, the illustrated track


60


, rails


82


and follower assembly


14


will be described in greater detail. While the illustrated arrangements comprise but one configuration, it is the presently preferred arrangement and other arrangements are possible. As discussed above, the track


60


generally comprises the support base


80


and the pair of rails


82


. The rails


82


preferably extend in a collinear fashion substantially the depth of the illustrated display rack


10


.




The illustrated rails


82


have a flattened upper surface to increase the support surface area for bearing the weight of the products. The upper surface, however, is not so large that increased friction may result, which friction would tend to oppose forward movement of product. In particular, based upon the forward feeding pressure provided by the follower assembly


14


, the sizing of the flattened upper surface of the rails preferably does not increase the frictional forces to a level that would not allow adequately free forward movement of the supported product.




The rails


82


further comprise a generally vertically extending rib


84


. The rib


84


spaces the rails


82


from the support base


80


. As illustrated clearly in

FIG. 6

, preferably the upper surface of the rails


82


, the rib


84


and the support base


80


create a double I cross-sectional shape. It should be understood that while the presently preferred product track


60


is a straight extrusion of the plastic material, it is envisioned that the rib


84


or the support base


80


, for instance, may be intermittent along the length of the rails


82


.




With continued reference to

FIG. 6

, an inner portion of the rails


82


terminate at an inward edge with a sloping tie down surface


86


. The tie down surface


86


cooperates with a pusher block


90


which reciprocates along the length of the product track


60


in manners which will be described in greater detail below.




The ends of the tracks


60


preferably are slideably connected to the front panel


16


and the rear panel


18


. More preferably, the ends of the tracks


60


carry end clips


92


that are slideably disposed within the races defined within the front panel


16


and the rear panel


18


. Of course, in some configurations, the end clips


92


are not used; however, the end clips


92


greatly increase the stability of the illustrated arrangement in which a track is moveable over a portion of a divider. and In general, each of the tracks


60


are generally restrained for translational movement (i.e., from side to side) along the front panel


20


and the rear panel


22


. Additionally, a secure connection of the product tracks


60


with the frame


12


is created when both the front and the rear of the track


60


are secured in races. The end clip


92


may be attached to the track


60


in any suitable manner, including friction fitting, threaded fasteners, fasteners, detents, and any other suitable method.




With reference now to

FIGS. 6 and 7

, the pusher block


90


comprises a spring or other biasing member


94


that biases the pusher block


90


toward a forward end of the track


6


. The pusher block


90


also features a sliding connection with the track


60


. The biasing member


94


preferably is a roll spring. The roll spring has characteristics that make it desirable over various other springs, such as compression springs. For instance, the roll spring naturally recoils after being extended and released. The recoiling involves rolling of the coil into its tightly wound initial state. Of course, coil springs may be used, however, they are not presently preferred. Moreover, elastic straps, ropes, and a variety of other springs and biasing members may be used. The roll spring may be permanently, semi-permanently or removably attached to the track


60


. It is presently preferred, however, that the roll spring be permanently or semi-permanently attached to the product track


60


using a rivet


96


. It is envisioned, however, that threaded fasteners, fasteners, pins, connectors and couplings of any suitable type may also be used. Of course, the end clip


92


also can be used to attached the biasing member


94


to the track


60


.




The portion of the biasing member


94


that is in contact with the pusher block


90


rests on a spring carrying surface


98


of the pusher block


90


. Due to the unique configuration of the roll spring, no permanent attachment or semi-permanent attachment is necessary to maintain the spring's position on the spring carrier surface


98


when the roll spring forms the biasing member


94


. Indeed, the forward tension of the roll spring, which would be opposed by any product positioned forward of the pusher block


90


, would help to maintain the position of the roll spring on the spring carrier surface


98


.




The illustrated pusher block


90


slideably connected to the track


60


. With continued reference to

FIGS. 3 and 6

, the pusher block


90


generally comprises a pair of inwardly extending flanges


100


and an inverted T-shaped hold down member


102


. The inwardly extending flanges


100


capture outer edges of the rails


82


while the T-shaped hold down member


102


captures the inner edges of the tie down surfaces


86


. By gripping both the inside and the outside of each rail


82


, the pusher block


90


is better secured to the track


60


and is less likely to inadvertently separate under twisting forces.




Various accessories may be added to the adjustable display rack


10


configured and arranged in accordance with the present invention. For instance, with reference to

FIGS. 6 and 7

, an increased size pushing paddle


110


is illustrated therein. The pushing paddle


110


increases the contact surface area between the product being moved forward and the pusher block


90


. Specifically, the paddle


110


is arranged with a pair of inwardly extending flanges


112


that are sized and configured to create a channel that slip fits over a product pushing surface


114


of the pusher block


90


.




Generally, the components of the display rack


10


may be comprised of any suitable material. Materials presently preferred are materials from the styrene family or self-lubricating FDA approved plastics, such as, but not limited to, acrylonitrile-butadiene-styrene (ABS). In some embodiments, however, the components may be manufactured from stainless steel, UHMW, or other FDA approved materials. The materials preferably are chosen to allow for easy cleaning and to reduce adsorption of liquids. In applications not involving food products, the materials may be chosen from any material considered desirable to those of the user. Where materials are not judiciously chosen to result in a self-lubricating nature to the product, materials such as brass or bronze or any other bearing type surface material may be utilized with steels and the like. Additionally, a silicon spray may be used to coat the surfaces to increase the lubrication between the moving components.




In some arrangements, the front panel


16


may be opaque, transparent or translucent. In the present and preferred embodiment, the front panel


16


is comprised of a clear plastic material to allow the prospective purchaser a clear line of vision to the product being carried by the adjustable display rack


10


.




When assembling the above-described display rack


10


, the track


60


preferably comprises at least one end clip


92


. The track


60


is positioned atop of a divider


62


between a chosen set of ribs


74


,


76


. The track


60


and the divider


62


are then assembled to the frame


12


. For instance, the end clip


92


is inserted into the respective race
