Description
GRAVITY-FEED SH~I.F AND CO~PONENTS THEREFOR
This invention relates ~o gravity--feed shelves and more psecifically to track6 used in æuch shelves. These tracks are arranged to form one or more forwardly and downwardly inclined chutes adapted to support rows of articles such as bottles or packages and fac~litate the forward feeding move-ment of such articles wlth a minimum degree of friction.
Tracks of the type in question are disclosed in Canadian Patent No. 1,158,822 granted December ~0, 198~, and Canadian Patent No. 1,150,179 granted July 19, 1983, both owned by the assignee of the present invention. ~ile such tracks have experienced considerable success, there is a need for tracks which can be arranged in a Yariety of patterns to accommodate packa~es or bottles of various ~izes.
Shelves u~ilizing tracks according to this invention are characterized by versatility of use, low friction, simplic-ity of construction and a high degree of economy in both initial and maintenance cos~s. According to one aspect of this invention, there is pro~ided a track for a gravi~y-feed shelf, which track comprises a web panel, a flange panel integral with one side edge of sald web panel and forming therewith a ~ubstantially 'IL"-shaped structure~ a plurallty of æubstantially parallel rlbs formed on one ~urface of said web panel between said flange panel and the opposite side edge of said web panel, characterized in that means is pro-vided on said web panel to form at least one frangible zoneby which a portion of the web panel can be broken away from an adjacent portion to reduce ~he width of ~he web panel.
Another aspect of ~hls inven~on provides a gra~ity-feed 6helf comprising a substantially rigid support frame and 30 including a support surface disposed in a plane which is . .
~ ~ 8 Docket D 2123 -2-forwardly and d3wnwardly lnclined, a plurality of elongate tracks located on said support surface, each track c~mprising a web panel having an undersurface in contact with said support surface and a flange panel integral with one side edge of said web panel and forming therewith a substantially "Lll-shaped structure, characterized in that the flange panel of one track is located adjacent the side edge of an adjacent track remote from its flange panel, thereby providing an inclined chute formed by the flange panel of said one track and the web and flange panel6 of said adjacent track.
Yet another aspect of this invention provides a gravlty-feed shelf comprising a substantially rigid support frame and including a support surface disposed in a plane which is forwardly and downwardly inclined, a plurality of elongate tracks located on said support surface, each track comprising a web panel having an undersurface in contact with said support surface and a flange panel integral ~ith one side edge of said web panel and forming therewith a substan-tially "L"-shaped structure, characterized in that two adjacent tracks are disposed in mutually reversed orientation so that the side edge of one track remote from its flange panel is located adjacent the side edge of an adjacent track remote from its flange panel thereby providing an inclined chute formed by the flange and web panels of one track and the flange and web pa~els of said adjacent track.
Embodiments of the invention will now be set forth by way of example and taken in conjunc~ion with the accompany-ing drawings, in which:
Figure 1 is a cross-sectional view taken through a track according to one aspect of the invention, Figure 2 is a perspective view oi a series of tracks located to give one pos&ible arrangement of shelving chutes, Figure 3 is a cross-sec~ional view of a series of tracks located to give another possible arrangement of shelving chutes, and Figure 4 is a cross-sectional view through a display shelf incorporating tracks according to the invention.
Docke~ D-2123 _3_ Referrlng to the drawings, Figure l illustrates in cross-seetion an elongate track l, comprising web panel 2 having an upper surface 3 and an undersurface 4, and a flange panel S integral with one side edge of the web panel 2 Thus, web panel 2 and flange panel 5 together form a track having a generally "L"-shaped s~ructure. A guide 1ange 6 iB integrally formed at the top edge of flange panel 5 thereby giving flange panel 5 a "T"-shaped cross-sectional configuration.
For the purpose of minimizing friction between the bottles and/or packages to be accommodated on the track, a plurality of upwardly projecting parallel ribs 7-18 is inte-grally formed along the upper surface 3. Each of the ribs is of generally triangular cross-sectional conflguration.
In order to allow the width of the web panel of track 1 to be reduced an elongate notch 19 is formed in the undersurface 4 of web panel 2 adjacent the free edge 20 of the web panel remote from flange panel 5. The no~ch 19 extends parallel to the ribs 7-18 and is located intermediate ribs 9 and 10 thereby forming a frangible zone extending along the whole length of the web panel 2. To reduce the width of ~he track it is necessary simply to raise the end section 21 as shown in phantom in Figure 1 60 ~hat end section 21 breaks away from the adjacent section of the web panel 2 along ~he frangible zone. End section 21 may then be discarded ~hereby leaving that portion of the web panel 2 having ribs 10-18.
It is envisaged that the notch 19 could be formed in the upper surface 3 of web panel 2. It also is envisaged that some means other than a notch could be provided to form the frangible zone. For example, a series of perforations or scored areas could be formed in the web panel. Furthermore, in some embodiments of the invention it may be appropriate to have more than one frangible æone along the web panel so as to provide a plurality of break-away sections.
Experience has shown that the track 1 may constitute an extrusion and may be formed of polyvinyl chloride or, it desir~d, may be formed of high impact polystyrene material.
S
Docket D-2123 -4-Also, in order to provide means for reducing frictlon between the ribs 7 18 and the bottom of articles disposed ~hereon, pol~-styrene may have silicone or some other suitable lubricant material dispersed therein during the manufacturing process so that even though the upper surfaces of the ribs 7-18 may wear, in use, the lubricating action of the lubricant mater~al is always effective because the structure is substantially homogeneous.
To provide a series of chutes "Cl", "C2" on a display shelf two arrangements of tracks are shown, by way of example, in Figures 2 and 3, respectively, of the drawings.
In Figure 2 the tracks are all disposed in the same side~by-side orientation and have all had their end sec~ions broken away and discarded As shown, the free edge of the web panel of each track (except ~he extreme lef~ hand track) is located nex~ to the flange panel of an adjacent track. This arrangement pro-vides a number of chutes "C" which each comp-rise the flange panel 5 of one track and the web and flange panels 2, 5, respec-tively, of an adjacent track. The arrangement is most suitable ~0 for accommodating on each chute "Cl" and "C2" a row of single packages and/or bottles.
In Figure 3 ~he chutes "C3" and "C4" are each formed by two tracks located side-by-side with the free edge of the web panel 2 of one track located next to the free edge of the web panel 2 of an adjacent track. In the case of chute "C3"
both web panels 2 have had their end sections broken away and discarded whereas in the case of chute "C4" both web panels have their end sec~ions intact. Chute "C3" is suitable for accommodating small mul~l-packs, e.g. six-packs, and chute "C4", which is of larger width, is suitable for accommodating relatively large multi-packs, Of course, any combina~ion of the track arrangements shown in Figures 1 and 2 is feasible.
In either arrangement, it will be appreclated ~hat ~he guide flanges 6 are provided ~o assist in guiding articles during movement down the chutes whlle keeping the contac~ bPtween the packages or bottles and flange panels 5 to a minimum. Also, Docket D-2123 -5-it is not necessary to locate adjacent tracks in abutment with one another, as shown, since some small amount of spacing between adjacent tracks is permissable without impairing the low frictional relationship between the articles and the tracks, Figure 4 illustrates a gravity-feed shelf 22 pro-viding part of a support frame and incorporating a series of ~racks l arranged to provide a row of inclined chutesO Shelf 22 comprises a front support element 23, an intermediate support element 24 and a rear support element 25. The support elements ~3, 24, 25 include upwardly facing support surfaces 26, 27, 28, respectively, all disposed in a common plane which is forwardly and downwardly inclined. Preferably a plannar suppor~ panel 29 is seated on support surfaces 26, 27 and 28 which provides an uninterrupted surface on which the undersurface 4 of each track, as at l, is located. Thus, the tracks and hence ~he chutes are tilted downwardly toward the front end of shelf 22. It will be understood $hat 2 row of articles disposed on a chute au~omatically is fed in the direction of inclination of the chute upon removal of the leading article in the row. The angle of tilt from the hori-zontal may vary somewhat but experience has shown that this angle preferably should be between 3~ minimum tilt to a maximum til~ of approximately 8. The an~le of tilt for mos~
applications of the invention should be approximately 6 from horizontal.
The front support element 23 of the shelf includes a stop member 30 comprising a wire guard which is slot~ed lnto a rearwardly protruding bead 31. ~1hen bottles and/or packages are accommodated on the chutes located on such a shelf there is a natural tendency for those articles auto--matically to slide downwardly and forwardly of ~he shelf so that the lowermost article has its sliding movement arrested by stop member 30 and normally rests against the bead 31.
In order to locate the tracks l in position on a shelf lt is necessary simply to flex each ~rack and inser~
~ 35 Docket D-2123 -6-the opposite ends thereof into the channel shaped recesses 32, 33 provided by the fr~nt and rear support elements 23, 25, respectively. Of course, if required the tracks may be secured to the support panel 29, when present, or to support surfaces 26, 27 and 28 by suitable fastening elements or by adhesive.
