Definitions
- This invention relates to a display unit.
- the display unit is equipped with shelves that may be adjusted in one or more dimensions relative to each other, as well as a mechanism for making such adjustments.
- Display units having multiple trays or shelves are well known. Such display units are generally provided with a frame, housing, or other construction to support the shelves. In such display units, multiple shelves may be pivotally attached to a frame, and the shelves may be provided with additional structures that support the shelves and their contents against the frame. Some display units further include shelves that may be adjusted along the horizontal or vertical axes.
- the adjustable display apparatus is provided with a housing, angled sliders, a plurality of shelves, an adjustment mechanism, and a bar linkage mechanism.
- the housing is provided with a pair of side walls and a plurality of supports.
- Each of the side walls is provided with a slider track that is disposed upon each respective side wall at an angle relative to the horizontal plane.
- the track is provided with a slot or a cutout that may extend the entire length of the track.
- the supports project downward from the housing and support the display apparatus on the ground.
- the angled sliders are elongate members that extend between the pair of side walls of the housing.
- Each of the angled sliders is provided with a first end, a second end, and a middle portion extending therebetween.
- the first end and second end of each angled slider is an elongate slider bar.
- the slider bar rests in the slider track, and therefore allows an angled slider to be supported by the two slider tracks between which it extends. Therefore, the sliders are disposed at an angle to the horizontal plane that is similar to the angle at which the slider track is positioned. This further allows for the angled sliders to slide up and down along the slider track at the predisposed angle.
- the slider bar is also provided with an aperture.
- Each of the plurality of shelves has a top surface and a pair of side surfaces, or shelf end plates.
- the side surfaces or shelf end plates extend in a generally downward direction from the top surface of the shelf.
- Each of the shelf end plates is provided with an aperture.
- a bolt or other fastener may then be used to pivotally affix the shelf to the slider bar. This arrangement allows the shelf to pivot about the point at which it is attached to the slider bar, as well travel along the slider track with the angled slider to which it is attached via the slider bar.
- Each shelf end plate is also provided with an additional support member that projects in a downward direction. This support member rests on the slider plate to which the shelf is attached when the shelf is in a downward pivoted position. When the shelf is in an upward pivoted position, the shelf is at an upward angle and the support member does not contact the slider plate.
- the movement of the shelves along the slider track is controlled by an adjustment mechanism that may take the form of a rotatable crankshaft.
- the adjustment mechanism includes a crank handle, although alternate methods of driving the adjustment mechanism may be used.
- an electric motor may be used to drive the adjustment mechanism.
- the crank handle is attached to a bar that extends from the front of the display unit to approximately halfway into the display unit, where the bar s met by a tube.
- the bar fits inside of the tube and is capable of sliding in a telescoping motion into and out of the tube, as well as rotating with the tube about their shared longitudinal axis in a manner that causes the tube to rotate as well.
- the tube extends from where it first meets with the bar to the rear portion of the display unit.
- the tube attaches to a threaded rod.
- a threaded nut is threaded onto the threaded rod between two rod bearings that are attached at either end of the threaded rod.
- the crank handle When the crank handle is rotated, the bar rotates with and telescopes into the tube. The turning of the bar causes the threaded rod to rotate. This results in the threaded nut traveling along the threaded bar in a linear path as the rod is threaded into and out of the nut.
- the bar linkage mechanism serves to couple the angled sliders and their attached shelves to the adjustment mechanism such that the adjustment mechanism is capable of adjusting the shelves.
- the bar linkage mechanism includes a pair of small bar linkages. One end of each of these small bar linkages attaches to either side of the threaded nut, such that there is one small bar linkage attached to the threaded nut on either side of the threaded rod along which the threaded nut may move.
- a common bar linkage also attaches to the other end of each of these small bar linkages, such that on either side of the threaded rod there is a small bar linkage attached to the threaded nut, with a common bar linkage further attached thereto.
- each of these common bar linkages is a plurality of additional connector linkages.
- the connector linkages couple the common bar linkage to each individual angled slider.
- one end of a connector bar is attached, and the other end of the connector bar linkage is attached to one of the angled sliders.
- each angled slider is attached to two individual connector bars, with one connector bar positioned on either side of the adjustment mechanism.
- Each connector bar is attached to the common bar on its respective side of the adjustment apparatus, and the common bar attaches to the threaded nut via the small bar linkage.
- Rotating the crank handle causes the threaded rod to rotate within the threaded nut, thereby moving the threaded nut in a linear direction along the threaded rod. If, for example, the threaded nut begins in a position closest to the rear of the display unit, and travels along a path towards the front of the display unit, the point of the common bar linkage that is attached to the small bar linkage follows this path, thereby causing one end of the common bar to travel towards the front of the unit, and the other end to be pivoted towards the rear of the unit.
- the common bar linkage is further attached to the adjustable display apparatus at a fixed pivot point about which this pivoting of the common bar linkage occurs as the threaded nut moves the common bar linkage.
- the display unit begins in the retracted position, and the crank handle is rotated such that the threaded nut moves from its position near the front of the display unit towards the rear of the display unit.
- the point of the common bar linkage that is attached to the small bar linkage follows this path, thereby causing one end of the common bar to travel towards the rear of the unit, and the other end to be pivoted towards the front of the unit.
- the common bar linkage pivots about its fixed pivot point, so all connector bar linkages that are attached to the common bar are also displaced towards the front of the unit.
- the connector bar linkages pull the connected angled sliders and the shelves to which they are attached in the general direction that they are travelling, causing the angled sliders to travel along the angled track that is disposed upon the sidewalls of the housing.
- This causes each of the plurality of shelves to travel in downward vertical and forward horizontal directions. That is, the shelves slide horizontally out from under one another and vertically out of one another, increasing the overall horizontal and vertical dimensions of the shelves. In this extended position, there is increased shelf surface area for displaying items.

Abstract
To control the amount of shelf space to maintain a fully stocked display with fluctuating amounts of product, a telescopic shelving apparatus is provided. The telescopic display apparatus includes a housing with a pair of side walls and an elongate track member disposed at an angle to a horizontal plane on each wall. The apparatus further includes a plurality of angled sliders extending between the walls and coupled with one of the elongate track members. A plurality of adjustable shelves are each attached to a respective one of the angled sliders. A common control mechanism, along with the elongate track members, allows the sliders and their attached adjustable shelves to simultaneously extend or retract vertically as well as horizontally.
Description
- This application claims priority from U.S. provisional patent application Ser. No. 62/027,987, filed Jul. 23, 2014, the contents of which are incorporated herein in their entirety.
- This invention relates to a display unit. The display unit is equipped with shelves that may be adjusted in one or more dimensions relative to each other, as well as a mechanism for making such adjustments.
- Display units having multiple trays or shelves are well known. Such display units are generally provided with a frame, housing, or other construction to support the shelves. In such display units, multiple shelves may be pivotally attached to a frame, and the shelves may be provided with additional structures that support the shelves and their contents against the frame. Some display units further include shelves that may be adjusted along the horizontal or vertical axes.
- Current display units present a problem as items are removed from the display surfaces. As fewer items are present on a shelf, the shelf begins to appear empty, which may be visually unappealing. Current display units do not provide a way to simultaneously adjust multiple shelves in both the horizontal and vertical directions using a single mechanism for the purpose of reducing the total amount of visual shelf space on a display unit in order to eliminate the unappealing aesthetic of an empty shelf. Accordingly, an adjustable display apparatus including a mechanism for the simultaneous adjustment of multiple shelves in the horizontal and vertical dimensions is desirable.
- An adjustable display apparatus is provided. The adjustable display apparatus is provided with a housing, angled sliders, a plurality of shelves, an adjustment mechanism, and a bar linkage mechanism.
- The housing is provided with a pair of side walls and a plurality of supports. Each of the side walls is provided with a slider track that is disposed upon each respective side wall at an angle relative to the horizontal plane. The track is provided with a slot or a cutout that may extend the entire length of the track. The supports project downward from the housing and support the display apparatus on the ground.
- The angled sliders are elongate members that extend between the pair of side walls of the housing. Each of the angled sliders is provided with a first end, a second end, and a middle portion extending therebetween. The first end and second end of each angled slider is an elongate slider bar. The slider bar rests in the slider track, and therefore allows an angled slider to be supported by the two slider tracks between which it extends. Therefore, the sliders are disposed at an angle to the horizontal plane that is similar to the angle at which the slider track is positioned. This further allows for the angled sliders to slide up and down along the slider track at the predisposed angle. The slider bar is also provided with an aperture.
- Each of the plurality of shelves has a top surface and a pair of side surfaces, or shelf end plates. The side surfaces or shelf end plates extend in a generally downward direction from the top surface of the shelf. Each of the shelf end plates is provided with an aperture. When a shelf is positioned in the housing, the aperture of a shelf end plate aligns with the aperture of a slider bar. A bolt or other fastener may then be used to pivotally affix the shelf to the slider bar. This arrangement allows the shelf to pivot about the point at which it is attached to the slider bar, as well travel along the slider track with the angled slider to which it is attached via the slider bar. Each shelf end plate is also provided with an additional support member that projects in a downward direction. This support member rests on the slider plate to which the shelf is attached when the shelf is in a downward pivoted position. When the shelf is in an upward pivoted position, the shelf is at an upward angle and the support member does not contact the slider plate.
- The movement of the shelves along the slider track is controlled by an adjustment mechanism that may take the form of a rotatable crankshaft. In one embodiment, the adjustment mechanism includes a crank handle, although alternate methods of driving the adjustment mechanism may be used. For example, an electric motor may be used to drive the adjustment mechanism. In the present embodiment, the crank handle is attached to a bar that extends from the front of the display unit to approximately halfway into the display unit, where the bar s met by a tube. The bar fits inside of the tube and is capable of sliding in a telescoping motion into and out of the tube, as well as rotating with the tube about their shared longitudinal axis in a manner that causes the tube to rotate as well. The tube extends from where it first meets with the bar to the rear portion of the display unit. Here, the tube attaches to a threaded rod. A threaded nut is threaded onto the threaded rod between two rod bearings that are attached at either end of the threaded rod. When the crank handle is rotated, the bar rotates with and telescopes into the tube. The turning of the bar causes the threaded rod to rotate. This results in the threaded nut traveling along the threaded bar in a linear path as the rod is threaded into and out of the nut.
- The bar linkage mechanism serves to couple the angled sliders and their attached shelves to the adjustment mechanism such that the adjustment mechanism is capable of adjusting the shelves. The bar linkage mechanism includes a pair of small bar linkages. One end of each of these small bar linkages attaches to either side of the threaded nut, such that there is one small bar linkage attached to the threaded nut on either side of the threaded rod along which the threaded nut may move. A common bar linkage also attaches to the other end of each of these small bar linkages, such that on either side of the threaded rod there is a small bar linkage attached to the threaded nut, with a common bar linkage further attached thereto. Attached to each of these common bar linkages is a plurality of additional connector linkages. The connector linkages couple the common bar linkage to each individual angled slider. At various points along the length of the common bar linkage, one end of a connector bar is attached, and the other end of the connector bar linkage is attached to one of the angled sliders. As this arrangement is the same on either side of the threaded rod, each angled slider is attached to two individual connector bars, with one connector bar positioned on either side of the adjustment mechanism. Each connector bar is attached to the common bar on its respective side of the adjustment apparatus, and the common bar attaches to the threaded nut via the small bar linkage.
- Rotating the crank handle causes the threaded rod to rotate within the threaded nut, thereby moving the threaded nut in a linear direction along the threaded rod. If, for example, the threaded nut begins in a position closest to the rear of the display unit, and travels along a path towards the front of the display unit, the point of the common bar linkage that is attached to the small bar linkage follows this path, thereby causing one end of the common bar to travel towards the front of the unit, and the other end to be pivoted towards the rear of the unit. The common bar linkage is further attached to the adjustable display apparatus at a fixed pivot point about which this pivoting of the common bar linkage occurs as the threaded nut moves the common bar linkage. Therefore, all connector bar linkages that are attached to the common bar are also displaced towards the rear of the unit. As this occurs, the connector bar linkages pull the connected angled sliders and the shelves to which they are attached in the general direction that the connector bar linkages are travelling, causing the angled sliders to travel along the angled track that is disposed upon the sidewalls of the housing. This causes each of the plurality of shelves to travel in upward vertical and rearward horizontal directions. That is, the shelves slide horizontally under one another and vertically into one another, reducing the overall horizontal and vertical dimensions of the shelves. In this retracted position, there is reduced shelf surface area for displaying items.
- In an alternative example, the display unit begins in the retracted position, and the crank handle is rotated such that the threaded nut moves from its position near the front of the display unit towards the rear of the display unit. The point of the common bar linkage that is attached to the small bar linkage follows this path, thereby causing one end of the common bar to travel towards the rear of the unit, and the other end to be pivoted towards the front of the unit. The common bar linkage pivots about its fixed pivot point, so all connector bar linkages that are attached to the common bar are also displaced towards the front of the unit. As this occurs, the connector bar linkages pull the connected angled sliders and the shelves to which they are attached in the general direction that they are travelling, causing the angled sliders to travel along the angled track that is disposed upon the sidewalls of the housing. This causes each of the plurality of shelves to travel in downward vertical and forward horizontal directions. That is, the shelves slide horizontally out from under one another and vertically out of one another, increasing the overall horizontal and vertical dimensions of the shelves. In this extended position, there is increased shelf surface area for displaying items.

FIG. 11 is a perspective view of an alternate embodiment of an adjustable display apparatus in the retracted position. - Referring now to
FIGS. 1 and 2 , a perspective view of anadjustable display apparatus 10 is shown. The display apparatus is provided with ahousing 20, which includes sidewalls 21 andsupport members 22. A plurality ofadjustable shelves 40 are supported by thehousing 20. InFIG. 1 , theshelves 40 can be seen in an extended position. InFIG. 2 , theshelves 40 can be seen in a retracted position. As shown, theadjustable shelves 40 are disposed in as rising steps from the front to the back of the housing. Theadjustable display apparatus 10 may further include a fixedtop shelf 12 disposed at the rear of the housing. Eachadjustable shelf 40 steps down from the fixed top shelf, being located horizontally forward of and vertically below the nextadjacent shelf shelves 40. - Referring now to
FIGS. 3 , 4, and 5, a partially transparent side view of anadjustable display apparatus 10 is shown. Aslider track 23 is mounted at an angle relative to a horizontal plane on or in each of sidewalls 21 ofhousing 20. Elongate slider bars 31 at the ends of angled sliders engage aslot 24 that is provided inslider track 23 to allow for support of the angled sliders and for adjustment of theadjustable display apparatus 10. This arrangement is more clearly shown inFIGS. 8 and 8D .Shelves 40 are disposed between thesidewalls 21 of thehousing 20. Each of theshelves 40 are provided with a generally horizontaltop surface 41, downwardly extending side surfaces 42, and a downwardly extendingfront surface 46.Side surface 42 may further be provided with asupport projection 44 and anaperture 43. When theshelves 40 are disposed between thesidewalls 21 of thehousing 20, afastener 45 pivotally couples theaperture 43 of each shelf to anaperture 32 that is provided in correspondingelongate slider bar 31. This allows theshelf 40 to move along theslider track 23 with theelongate slider bar 31, as well as to pivot about thefastener 45. -
FIG. 3 shows theshelves 40 in the extended position, wherein the vertical distances between thetop surfaces 41 ofshelves 40, as well as the horizontal distances between thefront surfaces 46 ofshelves 40, are at first distances.FIG. 4 shows theshelves 40 in the retracted position, wherein the vertical distances between thetop surfaces 41 ofshelves 40, as well as the horizontal distances between thefront surfaces 46 ofshelves 40, are at reduced values. As the shelves are retracted, theshelves 40 increasingly overlap each other. Eachshelf 40 may have an upwardly extendingrear surface 47 to prevent product from rolling off the back of each shelf. As shown inFIG. 4 , the front surface of one shelf overlaps the rear surface of the next lower shelf as the shelves are retracted.FIG. 5 shows theshelves 40 pivoted to an upward position about the connection betweenaperture 43 ofside surface 42 andaperture 32 ofelongate slider bar 31. - As will be clear to those of skill in the art, the
slider track 23 may be angled relative to horizontal and various angles depending on the desired vertical spacing of theshelves 40. In some embodiments, the slider track is angled in the range of 10 to 45 degrees. - Referring now to
FIGS. 6 and 7 , a partially transparent top view of anadjustable display apparatus 10 is provided. Thesidewalls 21 of thehousing 20 are provided with slider tracks 23. Both ends of angledsliders 30 are provided withelongate slider bars 31 that engageslider track 23 such thatangled sliders 30 may slide along the slider tracks 23. The sliding motion of the angledsliders 30 along slider tracks 23 is facilitated by adjustment mechanism 50. Adjustment mechanism 50 includes a crankhandle 51 that is coupled to bar 52. As can bee seen inFIG. 6 ,bar 52 extends intodisplay apparatus 10, where it is met bytube 53.Bar 52 is at least partially inserted intotube 53 such that thebar 52 may telescope in and out of thetube 53. Furthermore, rotation of crank handle 51 causes rotation of thebar 52 about its longitudinal axis. As thebar 52 is inserted into thetube 53, rotation of thebar 52 also causes rotation of thetube 53 about its longitudinal axis. In this manner, rotation of the crank handle 51 causes both thebar 52 andtube 53 to rotate about their shared longitudinal axis as thebar 52 telescopes within thetube 53. - The end of the
tube 53 into which thebar 52 is not inserted is attached to a threadedrod 54. Threadedrod 54 is inserted into a threadednut 55, which may be a high density plastic linear nut. As the rotation of the crank handle 51 causes the rotation of thebar 52 andtube 53, threadedrod 54 also rotates, causing the threadednut 55 to travel in a linear path along the threadedrod 54. That is, when the crank handle 51 is rotated in one direction, the threadednut 55 travels a linear path along the threadedrod 54 towards the front of theadjustable display apparatus 10. When the crank handle 51 is rotated in the opposite direction, the threadednut 55 travels a linear path along the threadedrod 54 towards the rear of theadjustable display apparatus 10. The movement of the threadednut 55 along the threadedrod 54 is limited byrod bearings 56. - Threaded
nut 55 is attached to abar linkage mechanism 60. The bar linkage mechanism includesshort bar linkages 61,common bar linkages 62, and connectingbar linkages 63.Short bar linkages 61 are coupled at one end to the threadednut 55. At their other end, theshort bar linkages 61 are coupled to one end of acommon bar linkage 62. A plurality of connectingbar linkages 63 are attached at one of each of their respective ends to thecommon bar linkage 62. That is, one end of each of the connectingbar linkages 63 is attached at a different location along the length of thecommon bar linkage 62. The other end of each of the connectingbar linkages 63 is attached to one of the angledsliders 30. The connectingbar linkages 63 may be of different sizes. For example, the connectingbar linkages 63 that are closest to thesidewalls 21 of thehousing 20 may be the longest connectingbar linkages 63, such that these connectingbar linkages 63 are attached at one end to acommon bar linkage 62 at the end of thecommon bar linkage 62 that is not attached to thesmall bar linkage 61. As this connectingbar linkage 63 is the longest, its other end may be attached to theangled slider 30 that is nearest to the front of theadjustable display apparatus 10. As an additional example, the connectingbar linkages 63 that are closest to the adjustment mechanism 50 may be the shortest connectingbar linkages 63, such that these connectingbar linkages 63 are attached at one end to acommon bar linkage 62. The other end of these connectingbar linkages 63 may be attached to theangled slider 30 that is nearest to the rear of theadjustable display apparatus 10. The attachment of the various components of thebar linkage mechanism 60 may be achieved by the use offasteners 64. - In one mode of adjustment of the
adjustable display apparatus 10, the threadednut 55 travels in a linear direction towards the front of theadjustable display apparatus 10. This causes thesmall bar linkages 61, which are attached to the threadednut 55, to be pulled in the direction of travel of the threadednut 55. As thesmall bar linkages 61 are pulled in this direction, they pull the end of thecommon bar 62, to which thesmall bar linkages 61 are attached, in the same direction towards the front of theadjustable display apparatus 10. As this end of thecommon bar 62 is pulled toward the front of thedisplay apparatus 10, thecommon bar 62 pivots about fixedpivot point 65. That is, the end of thecommon bar 62 that is attached to thesmall bar linkage 61 pivots toward the front of theadjustable display apparatus 10, while the end of thecommon bar 62 that is not attached to thesmall bar linkage 61 pivots toward the rear of theadjustable display apparatus 10. As thecommon bar 62 pivots about the fixedpivot point 65, the connectingbar linkages 63 that are each attached at one of their respective ends to thecommon bar 62 follow the end of thecommon bar 62 that is not attached to thesmall bar linkage 61. Therefore, the connectingbar linkages 63 travel toward the rear of theadjustable display apparatus 10. Because thecommon bar 62 pivots about the fixedpivot point 65, the connectingbar 63 that is attached to the end of thecommon bar 62 travels the greatest physical distance. The closer to the fixed pivot point 65 a connectingbar 63 is attached to thecommon bar 62, the less physical distance it travels. As the connectingbars 63 move, the ends of the connectingbars 63 that are attached to the angledsliders 30 each pull theangled slider 30 to which they are respectively attached toward the rear of theadjustable display apparatus 10. This causes the slider bars 31 to travel along the slider tracks 23 in both an upward and rearward direction. The distance that aslider bar 31 travels along the slider tracks 23 will be equal to the distance that the connectingbar 63 to which it is attached travels. Therefore, both the vertical and horizontal distances between theindividual shelves 40 attached to a respectiveangled slider 30 are decreased, but the distance that eachindividual shelf 40 moves will be different. This leads to an overall decrease in the area of thetop surface 41 of ashelf 40 that is available for use. However, because eachindividual shelf 40 travels a different distance, the area of thetop surface 41 of ashelf 40 that is available may be kept constant between theindividual shelves 40. - In another mode of adjustment of the
adjustable display apparatus 10, the threadednut 55 travels in a linear direction towards the rear of theadjustable display apparatus 10. This causes thesmall bar linkages 61, which are attached to the threadednut 55, to be pulled in the direction of travel of the threadednut 55. As thesmall bar linkages 61 are pulled in this direction, they pull the end of thecommon bar 62, to which thesmall bar linkages 61 are attached, in the same direction towards the rear of theadjustable display apparatus 10. As this end of thecommon bar 62 is pulled in this direction, thecommon bar 62 pivots about the fixedpivot point 65. That is, the end of thecommon bar 62 that is attached to thesmall bar linkage 61 pivots toward the rear of theadjustable display apparatus 10, while the end of thecommon bar 62 that is not attached to thesmall bar linkage 61 pivots toward the front of theadjustable display mechanism 10. As thecommon bar 62 pivots about the fixedpivot point 65, the connectingbar linkages 63 that are each attached at one of their respective ends to thecommon bar 62 follow the end of thecommon bar 62 that is not attached to thesmall bar linkage 61. Therefore, the connectingbar linkages 63 travel toward the front of theadjustable display apparatus 10. As this occurs, the ends of the connectingbars 63 that are attached to the angledsliders 30 each push theangled slider 30 to which they are respectively attached toward the front of theadjustable display apparatus 10. This causes the slider bars 31 to travel along theslider track 23 in both a downward and forward direction. Therefore, both the vertical and horizontal distances between theindividual shelves 40 attached to a respectiveangled slider 30 are increased. This leads to an overall increase in the area of thetop surface 41 of ashelf 40 that is available for use. In this mode of adjustment, the distances moved by theindividual shelves 40 differ in the same manner that they do when theadjustable display apparatus 10 is adjusted to allow for an overall decrease in shelf space, as previously described. Similarly, this mode of adjustment also allows for the available area of thetop surface 41 of ashelf 40 to be kept constant between theindividual shelves 40, even as the overall available shelf space is increased. - Referring now to
FIGS. 8A-C , perspective views of ashelf 40 of anadjustable display unit 10 are provided.FIG. 8A is a perspective view of ashelf 40 in an upward pivoted position. Theside surface 42 andfront surface 46 ofshelf 40 are visible, as well as thesupport member 44 of theside surface 42. Therear surface 47 is also shown in the Figures. Additionally, theangled slider 30 and theelongate slider bars 31 attached thereto are shown.Fastener 45 that attaches theside surface 42 of theshelf 40 to theelongate slider bar 31 of theangled slider 30 is also visible. This attachment serves as the pivot point for the pivoting motion of theshelf 40 with relation to theangled slider 30.FIG. 8B is a transparent perspective view of theshelf 40 in a downward pivoted position. Thesupport member 44 of theside surface 42 engages theangled slider 30 in this position.FIG. 8C is a perspective view of theshelf 40 in the downward position. Thetop surface 41,side surface 42,front surface 46, andrear surface 47 of theshelf 40 are visible. Theelongate slider bar 31 is also shown. - Referring now to
FIG. 9 , a front perspective view of anadjustable display unit 10 is provided. Thehousing 20 is further provided withsidewalls 21 andsupport members 22. Theshelves 40 extend between the sidewalls 21. - Referring now to
FIGS. 10 and 11 , perspective views of alternative embodiments of anadjustable display apparatus 10 are provided. Theadjustable display apparatuses 10 shown inFIGS. 10 and 11 are substantially similar to those previously described, with the added feature ofadditional shelving 70. InFIG. 10 , anadjustable display apparatus 10 in the extended position is shown, with oneadditional shelf 70 extending from the front of theadjustable display apparatus 10. InFIG. 11 , an adjustable display apparatus in the retracted position is shown, with twoadditional shelves 70 extending from the front ofadjustable display apparatus 10. The additional shelves are provided adjacent the front of the housing and below the adjustable shelves. The additional shelves may be horizontally slidable from a retracted position where they do not extend beyond the front of the housing to an extended position where they extend from the front of the housing. - The present invention provides an adjustable display apparatus with shelves that are simultaneously adjustable in the vertical and horizontal directions. A slider track that is provided on the housing of the apparatus engages angled sliders onto which the shelves are attached. An adjustment mechanism causes a bar linkage assembly that is attached to the angled sliders to pivot about a fixed point. This pivotal movement slides the angled sliders and the shelves attached thereto along the angled track. As the shelves slide along the track, the total available shelf area of the storage unit may be increased or decreased to a desired amount. Thus, the available shelf area may be adjusted to accommodate the volume of items that need to be displayed.
