- This invention is directed to a retail merchandise display unit that can be used to display and store merchandise in the form of individual items that will be removed from the shelves forming the retail display unit. More particularly, this invention is directed to a refrigerated retail display unit or chiller that can replace a standard shelving unit without disturbing standard retail shelving sections that would remain on either side of the refrigerated retail display unit.
- Merchandise is commonly displayed and stored on shelves.
- Spring loaded pusher systems are also mounted on the shelves to push items in different rows forward when the item at the front of a particular row is removed.
- These conventional displays are typically used with items that can be displayed and stored at room temperature.

- the straps 110 can obstruct the product on the shelves 102 during movement. For example, a relatively tall product on a shelf 102 might be wedged against a strap 110 located on the side or knife brackets 106 , 108 on which the shelf above rides. This would require greater clearance and therefore reduce the storage density of product stored therein.

- FIG. 1 shows a retail product display and storage unit or section 2 that includes a refrigerated compartment 10 that can be referred to as a chiller.
- This refrigerated unit 2 can be employed in combination with standard merchandise display sections 16 and 18 on either side. This allows merchandise items 8 that should be maintained at a lower temperature than normal to be stored and displayed next to other merchandise that may not require special care, but which may not offer the margins to the retailer that can be realized from these refrigerated items 8 . However, these refrigerated items 8 can be part of the same general product category as the other items that should be displayed in close proximity. Since the volume of product displayed is an important consideration, the substitution of a refrigerated product display and storage unit 2 for a standard display section cannot significantly reduce the number of items on display.
- the refrigerated product display and storage unit 2 should be within a range which would allow the refrigerated unit 2 to be interchangeable with one of the conventional sections 16 or 18 .
- additional refrigeration components are necessary, it follows that the item storage volume should be a very high percentage of the available display space or volume.
- the shelf assembly 20 in the refrigerated storage compartment 10 should allow as much of the available space to be filled with product or items 8 as possible. It follows that the items 8 will be stored together as closely as possible.
- the shelf assembly 20 should nevertheless provide product handling capabilities, such as product pusher subassemblies 90 in which product or items 8 stored in rows are advanced after the front product is removed by a customer or by a store employee.
- the shelf assembly 20 must allow items to be stocked and to be recycled or rearranged as appropriate.
- the instant invention is intended to increase product storage and display space by placing shelves 40 close together so that only the front item is accessible, and these closely spaced shelves 40 will slide out for restocking. In addition these shelves 40 will tilt when the shelf is in its extended position as shown in FIG. 1 .
- nine shelf levels 22 as seen in FIG. 2 are provided resulting in minimal product headroom between shelves 40 . Tilting not only facilitates restocking, but may be necessary for the upper rows of a shelf assembly 20 , which might not be conveniently accessible to a person of normal height, either to restock the merchandise or in some cases even to remove an item 8 located on the front of a row.
- FIG. 2 shows a shelf subassembly 20 and a mounting frame 30 on which the shelves 40 are mounted.
- This mounting frame 30 comprises squared mounting member on which the individual shelves 40 can slide smoothly between a retracted position and an extended position along a planar path to prevent binding and so that the shelves 40 will not be canted, especially during extraction.
- this planar path will be level, although it should be understood that the shelves 40 can be angled, but the planar path on which they travel should also be at the same angle.
- the interior surfaces 12 of a refrigerated compartment 10 do not exhibit the dimensional tolerances that will allow the shelves 40 to be mounted directly to the refrigerated unit or to the walls of the refrigerated compartment 10 while achieving the same storage and product density while allowing smooth operation of the shelves 40 .
- This is believed to be due to the need to insulate the refrigerated compartment 10 , which results in the need for large clearances in a standard refrigerated compartment.
- the mounting frame 30 can be positioned in the refrigerated compartment 10 , close to the interior surfaces 12 , and then be leveled or squared independent of the contour of the refrigerated compartment interior surfaces 12 .
- This squared frame 30 will then properly position the shelf subassembly 20 and its components for reliable movement of the shelves 40 , while utilizing a large percentage of the available refrigerated storage space for the items 8 themselves.
- the four corner posts 32 and 34 are connected by braces 36 so that the entire frame 30 remains fairly rigid.
- the corner posts 32 and 34 remain square.
- these corner posts could be assembled individually or in pairs and then oriented so the posts 32 and 34 would be square forming true vertical reference lines.
- the mounting frame 30 can be inserted through the front door 14 of the refrigerator or chiller, and leveled or squared once inside the refrigerated compartment.
- the shelves 40 can then be mounted on the mounting frame 30 , which includes two front corner posts 32 and two rear corner posts 34 . Corner posts 32 and 34 are connected by frame braces 36 and by a frame base 38 .
- the braces 36 and the base 38 are located on the periphery of the mounting frame 30 , which does not include any straps extending between the sides of the mounting frame 30 within the periphery of the mounting frame 30 . The absence of these straps eliminates interference with the shelves 40 and items 8 stored thereon during movement between an retracted position, in which the shelf is fully inserted, and an extended position.
- the absence of any straps extending over or above the shelves 40 prevents interference when the shelves 40 , and the items 8 stored thereon, are tilted, when the shelf 40 is in an extended position.
- the absence of straps means the less vertical spacing is necessary between shelf levels 22 , thus increasing item storage volume.
- the mounting frame 30 is fabricated from metal members to provide sufficient rigidity to this structure.
- the absence of straps extending over the shelves 40 or between side brackets 50 means that the side brackets 50 can be positioned at virtually any point along the corner posts 32 and 34 . Thus the side brackets 50 and the shelves riding thereon can be positioned as a function of the size of the items or product to be stored thereon.
- Knife brackets 50 will engage each shelf 40 on opposite sides.
- a number of knife brackets 50 equal to the number of shelf levels 22 will be mounted on opposite sides of the mounting frame 30 .
- Each side or knife bracket 50 has a front portion or end 52 attached to a front frame corner post 32 and a rear portion or end 54 attached to a rear frame corner post 34 .
- each knife bracket 50 comprises an upright section 56 extending between the front and rear ends 52 , 54 , and a mounting piece 66 attachable to the interior of the upright section 56 at the rear end 54 .
- a lower flange 58 extends from the upright section 56 , and extends inward from the interior surface of upright section 56 . The lower flange 58 can provide support for the rear of the shelf 40 in its retracted position.
- Two arcuate slots 60 extend through the upright bracket section 56 adjacent the front end 52 . These arcuate slots 60 are of different lengths, with the forward slot 60 being shorter than the rearward slot 60 , although it should be noticed that these arcuate slots 60 subtend a common angle measured relative to an opening 86 , which will form a pivot point for a glide member 70 that will be mounted on each side bracket 50 , as will be subsequently discussed in greater detail.
- the bracket mounting piece 66 includes three rearwardly extending, but downwardly facing hooks 62 . These hooks 62 are insertable into openings 35 , shown in FIG. 4B to mount the side or knife bracket 50 to a corresponding rear corner post 34 . Since there are a row of openings 35 located on each rear corner post 34 , the side brackets 50 can be mounted at different heights, depending upon the particular application, including the height of the items to be stored on specific shelves 40 . Spacing between shelves 40 is therefore a function of the relatively close spacing between these openings 35 . Each side bracket 50 also includes a tongue 64 that is struck from the upright section 56 closer to the front end 52 than to the rear end.
- This tongue 64 has a rearwardly facing free end, and the tongue 64 extends outwardly from the upright section 56 .
- This tongue 64 will extend over the front edge of the corresponding front frame corner post 32 to attach the side bracket 50 to the front post 32 while the hooks 62 secure the side bracket 50 to the rear post 34 .
- the tongue 64 will provide lateral positioning between the side bracket 50 and its corresponding front corner post 32 , but there is significance leeway for the fore and aft relationship between the side bracket 50 and a corresponding front corner post 32 , because it is not necessary to fully inset the leading edge of the front corner post 32 in the slot formed by the tongue 64 .
- FIG. 4B shows the rear of the side bracket fully inserted so that the hooks 62 will be secured in three appropriate openings 35 in the rear corner post.
- FIG. 4C shows the tongue 64 engaging the front frame corner post 32 .
- Each side bracket 50 will then be attached to front and rear corner posts 32 , 34 of the squared frame 30 , and will form a planar path along which the shelves 40 can be moved in a straight line during insertion and extraction. Side brackets 50 on each level will thus be accurately aligned.
- Each shelf 40 includes metal side or slide channels 42 forming the sides of the shelf 40 . These channels are joined at the front and rear by lateral supports 44 and 46 to form a rigid member.
- the side channels 42 have a U-shaped cross section and each channel 42 opens outwardly.
- the side channels 42 are dimensioned to receive a single glide member 70 as the shelf 40 moves between a retracted and extended position. The lower lip of each channel 42 will be positioned between the glide member 70 and the lower flange 58 on the side bracket 50 .
- Glide member 70 comprise one piece members which preferably are fabricated from a plastic that will provide sufficient lubricity to allow the glide member to slide within the shelf side channel 42 with little friction. These glide members 70 can also be referred to as slide members since slide or guide in the side channels 42 . Glide members 70 are mounted adjacent the front end 52 of each side bracket 50 to the interior surface of the upright bracelet section 56 . The glide members 72 will fit within a corresponding side channel 42 on a shelf 40 . As the shelf 40 moves from a rear, retracted position, the glide members 72 will move along a straight path allowing the shelf to move in a straight line along a planar path.
- the shelf 40 will tilt as it reaches its extended position because the glide members, supporting the shelf 40 , will pivot relative to the side bracket 50 on which it is mounted.
- Each glide member 70 is mounted to a side bracket 50 by a pivot pin 84 that extends from the front housing end 78 into a pivot opening 86 on the side bracket 50 .
- As the shelf 40 with items of merchandise 8 stored thereon, moves forward it will ultimately reach a point where the center of gravity of the loaded shelf 40 moves past the axis formed by the pivot pin 84 , and then gravity acting upon the loaded shelf 40 will cause the two glide members 70 supporting it to rotate about this axis of rotation, thus allowing the loaded shelf to tilt to the position shown in FIG. 6A .
- the shelf 40 When the shelf 40 reaches this extended position, it can rotate or tilt because there are no straps or cross pieces extending above the shelf 40 , which might obstruct items 8 stored on the shelf 40 .
- the straps 110 shown in the prior art configuration of FIG. 11 are absent from the strapless configuration of this invention, and the pair of side brackets 50 are not connected by straps extending above or below the corresponding shelf 40 .
- the rigidity that might have been provided by a strap has been replaced, in this strapless configuration by the rigid, peripheral mounting frame 30 or by squared and anchored corner posts 32 and 34 to which the immovable side or knife brackets 50 are secured.
- the weight and number of items 8 that are present on the shelf 40 will differ depending upon the loaded condition of the shelf.
- the pusher subassemblies 90 on each shelf will insure that the items 8 are moved forward, and the center of gravity of a partially loaded shelf 40 may even be further forward than a fully loaded shelf 40 .
- the extended position at which the loaded shelf 40 begins to tilt can vary depending upon the weight and number of items 8 on the shelf 40 , the shelf 40 will still be sufficiently clear of shelves 40 above and below the tilting shelf, so that there will be no interference.
- the glide member 70 extends rearwardly from the front pivot pin 84 .
- Pins 88 extend beyond the inner surface of the glide members 70 .
- each of this pins 88 extend through the guide member 70 into one of the arcuate slots 60 on the side or knife bracket 50 .
- the ends of the arcuate slots 60 thus serve to limit the movement of pins 88 and therefore limit the angle through which the glide member 70 can tilt.
- the tilt of the glide member 70 determines the degree of tilt of the shelf 40 , because the glide members 70 are captured in the shelf channels 42 .
- a stop pin 89 extending through the rear shelf lateral support 46 will engage the rear of the glide members 70 when the shelf 40 is in a fully extended position so that the shelf 40 will not fall free of the side brackets 50 .
- the glide members 70 also include a notch 82 located on its upper surface. A downwardly extending lip on the front shelf lateral support 44 will engage this notch 82 when the shelf 40 is in its retracted position, to hold the shelf 40 in place. Thus removal of an item 8 from the shelf 40 will not cause the shelf to move forward from its normally operative retracted position. A slight upward movement of the front end of the shelf 40 will clear this notch 82 so that the shelf 40 is free to slide from the retracted position toward the extended position.
- This strapless shelf assembly can employ a conventional pusher subassembly 90 for storing the merchandise items in parallel rows.
- the representative embodiment of a pusher subassembly 90 includes a pusher track 92 that can be mounted on a front strip 91 and a rear strip 93 . Mounting strips 91 and 93 can be secured respectively to the front and rear lateral shelf supports 44 and 46 . A tape or an adhesive can be employed.
- the individual tracks 92 are snapped into place in the front and rear strips 91 and 93 .
- Dividers 98 are also snapped into the strips 91 and 93 between the tracks 92 .
- a pusher 94 spring loaded by a coil spring 96 is mounted on each track, and the spring loaded pusher 94 will bias or push items in front of the pusher 94 toward the front of the shelf 40 so that as a front item 8 is removed those behind it are urged forward so that items in all rows are readily accessible.
- the pusher subassembly 90 depicted herein is merely representative and this invention is suitable for use with other conventional pusher systems.
- the pusher system could employ one-piece components with multiple tracks.

- the items 8 depicted herein are disk shaped. It should be understood however that the items with which this invention can be employed can have other shapes. For example, this invention is especially suited for rectangular items or packages. This invention is also suited for applications in which the height of the various items can be different, and this invention can even be employed in situations in which the height of items in different rows of the same shelf may be different. It should also be understood that this shelving system can be employed with room temperature displays as well as displays in which the items may maintained at an elevated temperature or subject to other restrictions.

Abstract
A shelf system for use in displaying and storing merchandise is especially suited for use in a refrigerated or chiller compartment that can be used with other conventional display sections. The shelving system or unit includes a squared frame that is mounted in a refrigeration compartment. Side or knife brackets are mounted on opposite sides of the frame and shelves on which items of merchandise are stored in spring loaded pusher track systems are mounted on the side brackets. Guide members mounted on the side brackets allow the shelves to slide between a retracted and an extended position on a planar path, but when the shelves reach the extended position, the glide members tilt allowing the shelves to tile for easier access to items stored thereon.
Description
- This application claims the benefit of prior co-pending U.S. Provisional Patent Application Ser. No. 61/626,844 filed on Oct. 4, 2011.
- 1. Field of the Invention
- This invention is directed to a retail merchandise display unit that can be used to display and store merchandise in the form of individual items that will be removed from the shelves forming the retail display unit. More particularly, this invention is directed to a refrigerated retail display unit or chiller that can replace a standard shelving unit without disturbing standard retail shelving sections that would remain on either side of the refrigerated retail display unit.
- 2. Description of the Prior Art
- Merchandise is commonly displayed and stored on shelves. Spring loaded pusher systems are also mounted on the shelves to push items in different rows forward when the item at the front of a particular row is removed. These conventional displays are typically used with items that can be displayed and stored at room temperature. In some cases, new and different premium items, which may compete with or be superior to the standard item, may require special storage conditions. For example it may be necessary to maintain these items at temperatures that are lower than room temperature. Thus refrigeration or chiller equipment must be employed.
- However, since the premium refrigerated items may be competitive with the standard items that require no special storage, a retailer or a product manufacturer may wish to display these items with standard items. Small cabinet mounted refrigeration units or countertop refrigerated or chiller units have been employed. However, these smaller units do not provide significant display space. A larger refrigeration unit or chiller could display more product, but if it is substituted for a standard display unit or section, it may not be cost effective unless the new refrigeration unit is capable of storing a large number of items in an available display space. Furthermore, the overall dimensions of such a unit will need to be similar to standard display sections if they are to be interchangeable.
- One problem with prior are
shelf display systems 100, such as that shown inFIG. 11 is the presence ofstraps 110 that extend either belowside brackets pusher systems 104 located onshelves 102, thestraps 110 can obstruct the product on theshelves 102 during movement. For example, a relatively tall product on ashelf 102 might be wedged against astrap 110 located on the side orknife brackets shelves 110 to enhance access to product or items on the shelves would also be restricted by the presence of thesestraps 110. If the straps extending between a frame on whichside brackets shelves 102 could only be mounted at select locations, limiting the versatility of the storage display system. The present invention eliminated the necessity for these straps and is therefore referred to as a strapless system. - According to one aspect of this invention, a shelf assembly is used to store and display merchandise. This shelf assembly includes a pair of side brackets mountable on a frame. Each side bracket includes glide members on an interior surface. A shelf subassembly is positioned between and supported by the pair of side brackets. Each shelf assembly includes outwardly facing slide channels extending along the side of each shelf subassembly. The glide members on the side brackets are received within the slide channels so that the shelf subassembly can travel fore and aft relative to the pair of side brackets as the glide members ride within the slide channels.
- The glide members are pivotally secured to the side bracket on which it is mounted. Movement of the shelf subassembly to an extended position imparts rotation to the glide members while the glide members remain within the slide channels. The shelf subassembly will then tilt, due to gravity, relative to the side brackets when in this extended position.
- A retail product display and storage assembly according to another aspect of this invention is used in a refrigerated compartment. This assembly includes a plurality of sliding shelves, stacked one above the other on multiple levels. A squared frame can be positioned in the refrigerated compartment. The frame includes four upright frame corner posts that form squared vertical reference lines not solely dependent upon interior surfaces of the refrigerated compartment. Side brackets are each secured to a rear frame corner post and a front frame corner post on one side of the frame. Two side brackets on the same level, one on each side of the frame, are held in position by the frame corner posts to form a planar path along which the sliding shelves will slide between a retracted and an extended position. Glide members on the side brackets are received in side channels on the shelves to allow the shelves to slide between the retracted to the extended positions.
- This invention also can comprise a strapless merchandise assembly for displaying and storing merchandise and providing an item storage volume equal to a large percentage of available display space. This assembly includes a plurality of slidable and tiltable shelves. Each shelf is mountable between two side brackets. These side brackets are independently held in fixed positions. Each shelf is mounted between pairs of side brackets, without straps extending laterally between side brackets forming a pair of side brackets either above or below each shelf. Each shelf slides relative to the pair of side brackets on which it is mounted between retracted and extended positions. Each shelf tilts relative to the pair of side brackets on which it is mounted only when the shelf is in the extended position. Each shelf has a channel on each side receiving glide members mounted on each side bracket. Each shelf slides along a planar path relative to the pair of side brackets on which it is mounted between the retracted and extended positions. Each glide member tilts when the shelf reaches the extended position so that the shelf will tilt due to gravity. The extended position at which each shelf tilts is dependent upon distribution of weight of items stored on that shelf. Each shelf is free to tilt without obstruction of items stored on the shelf by straps above and below the shelf so that shelves can be positioned relatively close together to increase the percentage of item storage volume relative to display space.

FIG. 1 shows a retail product display and storage unit orsection 2 that includes arefrigerated compartment 10 that can be referred to as a chiller. Thisrefrigerated unit 2 can be employed in combination with standardmerchandise display sections merchandise items 8 that should be maintained at a lower temperature than normal to be stored and displayed next to other merchandise that may not require special care, but which may not offer the margins to the retailer that can be realized from theserefrigerated items 8. However, theserefrigerated items 8 can be part of the same general product category as the other items that should be displayed in close proximity. Since the volume of product displayed is an important consideration, the substitution of a refrigerated product display andstorage unit 2 for a standard display section cannot significantly reduce the number of items on display. Furthermore, overall dimensions of the refrigerated product display andstorage unit 2 should be within a range which would allow therefrigerated unit 2 to be interchangeable with one of theconventional sections shelf assembly 20 in therefrigerated storage compartment 10 should allow as much of the available space to be filled with product oritems 8 as possible. It follows that theitems 8 will be stored together as closely as possible. Theshelf assembly 20 should nevertheless provide product handling capabilities, such asproduct pusher subassemblies 90 in which product oritems 8 stored in rows are advanced after the front product is removed by a customer or by a store employee. In addition, theshelf assembly 20 must allow items to be stocked and to be recycled or rearranged as appropriate. The instant invention is intended to increase product storage and display space by placingshelves 40 close together so that only the front item is accessible, and these closely spacedshelves 40 will slide out for restocking. In addition theseshelves 40 will tilt when the shelf is in its extended position as shown inFIG. 1 . In the representative embodiment, nineshelf levels 22, as seen inFIG. 2 are provided resulting in minimal product headroom betweenshelves 40. Tilting not only facilitates restocking, but may be necessary for the upper rows of ashelf assembly 20, which might not be conveniently accessible to a person of normal height, either to restock the merchandise or in some cases even to remove anitem 8 located on the front of a row. -
FIG. 2 shows ashelf subassembly 20 and a mountingframe 30 on which theshelves 40 are mounted. This mountingframe 30 comprises squared mounting member on which theindividual shelves 40 can slide smoothly between a retracted position and an extended position along a planar path to prevent binding and so that theshelves 40 will not be canted, especially during extraction. In the configuration depicted herein, this planar path will be level, although it should be understood that theshelves 40 can be angled, but the planar path on which they travel should also be at the same angle. - For normal construction, the interior surfaces 12 of a
refrigerated compartment 10 do not exhibit the dimensional tolerances that will allow theshelves 40 to be mounted directly to the refrigerated unit or to the walls of therefrigerated compartment 10 while achieving the same storage and product density while allowing smooth operation of theshelves 40. This is believed to be due to the need to insulate therefrigerated compartment 10, which results in the need for large clearances in a standard refrigerated compartment. The mountingframe 30 can be positioned in therefrigerated compartment 10, close to the interior surfaces 12, and then be leveled or squared independent of the contour of the refrigerated compartment interior surfaces 12. This squaredframe 30 will then properly position theshelf subassembly 20 and its components for reliable movement of theshelves 40, while utilizing a large percentage of the available refrigerated storage space for theitems 8 themselves. In the embodiment depicted herein the fourcorner posts braces 36 so that theentire frame 30 remains fairly rigid. However the important aspect of this frame is that the corner posts 32 and 34 remain square. In alternate embodiments these corner posts could be assembled individually or in pairs and then oriented so theposts - The mounting
frame 30 can be inserted through thefront door 14 of the refrigerator or chiller, and leveled or squared once inside the refrigerated compartment. Theshelves 40 can then be mounted on the mountingframe 30, which includes two front corner posts 32 and two rear corner posts 34. Corner posts 32 and 34 are connected by frame braces 36 and by aframe base 38. Thebraces 36 and the base 38 are located on the periphery of the mountingframe 30, which does not include any straps extending between the sides of the mountingframe 30 within the periphery of the mountingframe 30. The absence of these straps eliminates interference with theshelves 40 anditems 8 stored thereon during movement between an retracted position, in which the shelf is fully inserted, and an extended position. Furthermore, the absence of any straps extending over or above theshelves 40 prevents interference when theshelves 40, and theitems 8 stored thereon, are tilted, when theshelf 40 is in an extended position. The absence of straps means the less vertical spacing is necessary betweenshelf levels 22, thus increasing item storage volume. In the preferred embodiment, the mountingframe 30 is fabricated from metal members to provide sufficient rigidity to this structure. Furthermore, the absence of straps extending over theshelves 40 or betweenside brackets 50 means that theside brackets 50 can be positioned at virtually any point along the corner posts 32 and 34. Thus theside brackets 50 and the shelves riding thereon can be positioned as a function of the size of the items or product to be stored thereon. - The
individual shelves 40 are supported on the mountingframe 30 by side orknife brackets 50.Knife brackets 50 will engage eachshelf 40 on opposite sides. A number ofknife brackets 50 equal to the number ofshelf levels 22 will be mounted on opposite sides of the mountingframe 30. Each side orknife bracket 50 has a front portion or end 52 attached to a frontframe corner post 32 and a rear portion or end 54 attached to a rearframe corner post 34. As shown inFIG. 8B , eachknife bracket 50 comprises anupright section 56 extending between the front andrear ends piece 66 attachable to the interior of theupright section 56 at therear end 54. Alower flange 58 extends from theupright section 56, and extends inward from the interior surface ofupright section 56. Thelower flange 58 can provide support for the rear of theshelf 40 in its retracted position. - Two
arcuate slots 60 extend through theupright bracket section 56 adjacent thefront end 52. Thesearcuate slots 60 are of different lengths, with theforward slot 60 being shorter than therearward slot 60, although it should be noticed that thesearcuate slots 60 subtend a common angle measured relative to anopening 86, which will form a pivot point for aglide member 70 that will be mounted on eachside bracket 50, as will be subsequently discussed in greater detail. - The
bracket mounting piece 66 includes three rearwardly extending, but downwardly facing hooks 62. These hooks 62 are insertable intoopenings 35, shown inFIG. 4B to mount the side orknife bracket 50 to a correspondingrear corner post 34. Since there are a row ofopenings 35 located on eachrear corner post 34, theside brackets 50 can be mounted at different heights, depending upon the particular application, including the height of the items to be stored onspecific shelves 40. Spacing betweenshelves 40 is therefore a function of the relatively close spacing between theseopenings 35. Eachside bracket 50 also includes atongue 64 that is struck from theupright section 56 closer to thefront end 52 than to the rear end. Thistongue 64 has a rearwardly facing free end, and thetongue 64 extends outwardly from theupright section 56. Thistongue 64 will extend over the front edge of the corresponding front frame corner post 32 to attach theside bracket 50 to thefront post 32 while thehooks 62 secure theside bracket 50 to therear post 34. Thetongue 64 will provide lateral positioning between theside bracket 50 and its correspondingfront corner post 32, but there is significance leeway for the fore and aft relationship between theside bracket 50 and a correspondingfront corner post 32, because it is not necessary to fully inset the leading edge of the front corner post 32 in the slot formed by thetongue 64.FIG. 4B shows the rear of the side bracket fully inserted so that thehooks 62 will be secured in threeappropriate openings 35 in the rear corner post.FIG. 4C shows thetongue 64 engaging the frontframe corner post 32. Eachside bracket 50 will then be attached to front and rear corner posts 32, 34 of the squaredframe 30, and will form a planar path along which theshelves 40 can be moved in a straight line during insertion and extraction.Side brackets 50 on each level will thus be accurately aligned. - Each
shelf 40 includes metal side orslide channels 42 forming the sides of theshelf 40. These channels are joined at the front and rear bylateral supports side channels 42 have a U-shaped cross section and eachchannel 42 opens outwardly. Theside channels 42 are dimensioned to receive asingle glide member 70 as theshelf 40 moves between a retracted and extended position. The lower lip of eachchannel 42 will be positioned between theglide member 70 and thelower flange 58 on theside bracket 50. -
Glide member 70 comprise one piece members which preferably are fabricated from a plastic that will provide sufficient lubricity to allow the glide member to slide within theshelf side channel 42 with little friction. Theseglide members 70 can also be referred to as slide members since slide or guide in theside channels 42.Glide members 70 are mounted adjacent thefront end 52 of eachside bracket 50 to the interior surface of theupright bracelet section 56. Theglide members 72 will fit within acorresponding side channel 42 on ashelf 40. As theshelf 40 moves from a rear, retracted position, theglide members 72 will move along a straight path allowing the shelf to move in a straight line along a planar path. Theshelf 40 will tilt as it reaches its extended position because the glide members, supporting theshelf 40, will pivot relative to theside bracket 50 on which it is mounted. Eachglide member 70 is mounted to aside bracket 50 by apivot pin 84 that extends from thefront housing end 78 into apivot opening 86 on theside bracket 50. As theshelf 40, with items ofmerchandise 8 stored thereon, moves forward it will ultimately reach a point where the center of gravity of the loadedshelf 40 moves past the axis formed by thepivot pin 84, and then gravity acting upon the loadedshelf 40 will cause the twoglide members 70 supporting it to rotate about this axis of rotation, thus allowing the loaded shelf to tilt to the position shown inFIG. 6A . When theshelf 40 reaches this extended position, it can rotate or tilt because there are no straps or cross pieces extending above theshelf 40, which might obstructitems 8 stored on theshelf 40. Thestraps 110, shown in the prior art configuration ofFIG. 11 are absent from the strapless configuration of this invention, and the pair ofside brackets 50 are not connected by straps extending above or below the correspondingshelf 40. The rigidity that might have been provided by a strap has been replaced, in this strapless configuration by the rigid, peripheral mountingframe 30 or by squared and anchored corner posts 32 and 34 to which the immovable side orknife brackets 50 are secured. Of course, the weight and number ofitems 8 that are present on theshelf 40 will differ depending upon the loaded condition of the shelf. However, thepusher subassemblies 90 on each shelf will insure that theitems 8 are moved forward, and the center of gravity of a partially loadedshelf 40 may even be further forward than a fully loadedshelf 40. Thus although the extended position at which the loadedshelf 40 begins to tilt can vary depending upon the weight and number ofitems 8 on theshelf 40, theshelf 40 will still be sufficiently clear ofshelves 40 above and below the tilting shelf, so that there will be no interference. - The
glide member 70 extends rearwardly from thefront pivot pin 84.Pins 88 extend beyond the inner surface of theglide members 70. As can be seen inFIG. 5C , each of this pins 88 extend through theguide member 70 into one of thearcuate slots 60 on the side orknife bracket 50. The ends of thearcuate slots 60 thus serve to limit the movement ofpins 88 and therefore limit the angle through which theglide member 70 can tilt. The tilt of theglide member 70 determines the degree of tilt of theshelf 40, because theglide members 70 are captured in theshelf channels 42. Astop pin 89 extending through the rear shelflateral support 46 will engage the rear of theglide members 70 when theshelf 40 is in a fully extended position so that theshelf 40 will not fall free of theside brackets 50. Theglide members 70 also include anotch 82 located on its upper surface. A downwardly extending lip on the front shelflateral support 44 will engage thisnotch 82 when theshelf 40 is in its retracted position, to hold theshelf 40 in place. Thus removal of anitem 8 from theshelf 40 will not cause the shelf to move forward from its normally operative retracted position. A slight upward movement of the front end of theshelf 40 will clear thisnotch 82 so that theshelf 40 is free to slide from the retracted position toward the extended position. - This strapless shelf assembly can employ a
conventional pusher subassembly 90 for storing the merchandise items in parallel rows. The representative embodiment of apusher subassembly 90 includes apusher track 92 that can be mounted on afront strip 91 and arear strip 93. Mounting strips 91 and 93 can be secured respectively to the front and rear lateral shelf supports 44 and 46. A tape or an adhesive can be employed. In the representative embodiment shown herein, theindividual tracks 92 are snapped into place in the front andrear strips Dividers 98 are also snapped into thestrips tracks 92. Apusher 94 spring loaded by acoil spring 96 is mounted on each track, and the spring loadedpusher 94 will bias or push items in front of thepusher 94 toward the front of theshelf 40 so that as afront item 8 is removed those behind it are urged forward so that items in all rows are readily accessible. Thepusher subassembly 90 depicted herein is merely representative and this invention is suitable for use with other conventional pusher systems. For example, the pusher system could employ one-piece components with multiple tracks. Pusher systems similar to the representative embodiment depicted herein are discussed in greater detail in U.S. Pat. No. 7,201,281, which is incorporated by reference herein. The representative embodiment also shows a pusher system in which the larger frontal surface of the item faces forward. Another pusher system in which the items are positioned with narrower sides facing forward and which is also suitable for use in this invention, is shown in US Provisional Patent Application (Attorney's Docket Number 11034) filed Sep. 30, 2011 by Brian Welker and Greg Isaacs and entitled System for Advancing Merchandise in Different Orientations, which application is incorporated herein by reference. - The
items 8 depicted herein are disk shaped. It should be understood however that the items with which this invention can be employed can have other shapes. For example, this invention is especially suited for rectangular items or packages. This invention is also suited for applications in which the height of the various items can be different, and this invention can even be employed in situations in which the height of items in different rows of the same shelf may be different. It should also be understood that this shelving system can be employed with room temperature displays as well as displays in which the items may maintained at an elevated temperature or subject to other restrictions. - In an alternate embodiment the single
piece glide members 70, which merely slide alongchannels 42 without rotation, could be replaced by a member having wheels or rollers that rotate relative to a housing in which they are located. Thus the term glide members is not limited to bearing members that merely translate or slide without rotation.
