DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS

(15) While various aspects and features of certain embodiments have been summarized above, the following detailed description illustrates three exemplary embodiments in further detail to enable one skilled in the art to practice such embodiments. The described examples are provided for illustrative purposes and are not intended to limit the scope of the invention.

(16) In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the described embodiments. It will be apparent to one skilled in the art, however, that other embodiments of the present invention may be practiced without some of these specific details. Three embodiments are described herein, and while various features are ascribed to different embodiments, it should be appreciated that the features described with respect to one embodiment may be incorporated with other embodiments as well. By the same token, however, no single feature or features of any described embodiment should be considered essential to every embodiment of the invention, as other embodiments of the invention may omit such features.

(17) Unless otherwise indicated, all numbers herein used to express quantities, dimensions, and so forth, should be understood as being modified in all instances by the term about. In this application, the use of the singular includes the plural unless specifically stated otherwise, and use of the terms and and or means and/or unless otherwise indicated. Moreover, the use of the term including, as well as other forms, such as includes and included, should be considered non-exclusive. Also, terms such as element or component encompass both elements and components comprising one unit and elements and components that comprise more than one unit, unless specifically stated otherwise.

(18) As used herein, the term vertical refers to the ZY or ZX plane defined by Cartesian coordinate system and the term horizontal refers to the XY plane defined by Cartesian coordinate system.

(19) The present invention relates to a novel design for a horizontally and vertically adjustable shelf divider. It is constructed through injection molding with a suitable polymer. Its blade configurations are both corrugated for strength and have open cell arrays formed there through to remove unnecessary material and lighten the overall mass.

(20) FIGS. 3-6 illustrate that the adjustable height shelf divider 2 when assembled, is a unitary shelf divider that retains its vertical extension upper blade 6 behind its lower blade 10 in its lowered configuration, always at the ready for incremental adjustments in height. Looking at FIGS. 1 to 3 it can be seen that the adjustable height shelf divider 2 (first and preferred embodiment shelf divider) has a lower blade base assembly 4 and a vertically adjustably upper blade 6. The lower blade base assembly 4 has a slidingly adjustable horizontal shelf bracket 8 and a lower blade 10 which extends perpendicularly from the rear edge of the top face of the lower blade 10. As can be seen in FIGS. 3, 4 and 5, the upper blade 6 of the adjustable height shelf divider 2 may be vertically positioned in a lowered configuration or any of an incrementally, vertically adjustable, raised configuration. When in the lowered configuration the lower blade 10 and the upper blade 6 reside adjacent each other in a parallel, corrugated configuration as is best illustrated in the horizontal cross section of FIG. 6.

(21) Looking at FIG. 4, the lower blade base assembly 4 is a C shaped bracket that has a top face 12 that spans across the top of a shelf, two side arms 14 that extend perpendicularly from the opposing short edges of the top face and extend across the shelf sides for the thickness of the shelf, and two return flanges 16 that extend perpendicularly from the bottom edge of the side arms 14 so as to extend partially along the bottom face of the shelf. In this fashion, the lower blade base assembly 4 curves around a matingly conformed shelf, and holds the lower blade 10 perpendicular to the top surface of the shelf.

(22) Although not illustrated, as it forms no part of this invention, the shelf is a planar member generally rectangular or C shaped in cross section. The dimensional tolerances between the shelf and the lower blade base assembly 4 are such as to allow the horizontal sliding of the lower blade base assembly 4 along the shelf for horizontal positioning along the depth of the shelf. On the shelf are rows of oval orifices that matingly align with a pair of slots 18 formed through the top face 12. The adjustable height shelf divider 2 may be horizontally slid along the shelf to a specified depth until the slots 18 align with the orifices and a pair of locking pegs inserted there through to lock the vertical position of the adjustable height shelf divider 2. The locking pegs have low profile heads.

(23) In the preferred embodiment, the shelf bracket 8 and lower blade 10 are a single piece although in alternate embodiments these may be fabricated in separated pieces and joined. The lower blade 10 is vertically corrugated having alternating series of vertical ridges 20 and grooves 22 each of which have an array of open cells 24 formed there through. The upper blade 6 has a matingly engageable vertical corrugated configuration although its arrays of open cells may have different dimensions that that of the lower blade 10.

(24) The lower blade 10 has a series of linear ratchet slots 26 formed vertically along its centerline that matingly are engaged by a bendable ratchet tooth 28 located on the vertical centerline of the upper blade 6 at the bottom edge of the upper blade 6. Looking at FIG. 5 it can be seen that the ratchet tooth 28 has a linear, planar strip body attached at its top end to the upper blade 6 and free to flex horizontally at its bottom end. It has a tab 30 extending from its front face adjacent its bottom end that engages the ratchet slots 26 so as to lock the vertical position of the upper blade 6 relative to the lower blade 10. The bottom end of the ratchet tooth 28 is angled slightly from the vertical plane of the ratchet tooth body to allow for a tactile ratchet disengagement manipulation.

(25) There are four mechanisms that connect the upper blade 6 to the lower blade 10 and allow for their aligned sliding vertical engagement. (Reference FIGS. 1 and 6.) First, the lower blade 10 has a pair of vertical retention grooves 32 formed continuously along its left and right vertical edges. The upper blade 6 has matingly conformed right and left vertical slide edges 34 with a thickness that allows for sliding engagement of these side edges 34 of the upper blade 6 within the pair of retention grooves 32 of the lower blade 10. Second there are two parallel vertical slots 36 formed from the bottom of the lower blade to just short of the top edge of the lower blade 10. The upper blade 6 has a pair of T shaped tabs 38 that extend perpendicularly from its vertical front face. (See FIG. 4.) The head of the T shaped tab 38 is passed through an entry orifice 40 formed through the horizontal shelf bracket 8 where the vertical slots 36 of the lower blade 10 meet the shelf bracket 8. (Although it is known that in alternate embodiments only one T shaped tab and one parallel vertical slot may be used.) This entry orifice is wide enough to allow the head of the T shaped tab 38 to pass however the width of the vertical slots 36 is too narrow for the T shaped tab to exit. In this way, the largest part of the T shaped tab 38 is constrained on the front side of the lower blade 10 while the remainder of the upper blade 6 is constrained on the back side of the lower blade 10. This allows the upper blade 6 to be vertically adjusted while in parallel alignment with the lower blade 10 but the two blades constrained from separation by the left and right vertical retention grooves 32 and the T shaped tabs 38. Third, the engagement of the bendable ratchet tooth 28 in the vertical linear ratchet slots 26 serves to lock the upper blade 6 at the desired height. Fourth, the matching corrugation configurations of the upper blade and the lower blade allow the vertical faces of the two blades to be matingly engaged such that they remain parallel and adjacent throughout the vertical positioning of the lower blade, therein resisting horizontal separation and keeping the blades aligned.

(26) Looking now at FIGS. 7 to 9, the fixed blade adjustable height shelf divider 40 (second embodiment shelf divider) can be seen in its unassembled and assembled states. Note that the fixed height blade 44 also has a vertical corrugated configuration with the open cell arrays formed there through as seen in the preferred embodiment. This fixed blade adjustable height shelf divider 40 consists of a separable blade support shelf bracket 42 and a fixed height blade 44. The assembled separable blade support shelf bracket 42 and fixed height blade 44 bear striking similarities to the lower blade base assembly 4 of the preferred embodiment described above. The blade support shelf bracket 42 is also C shaped bracket that has a top face that spans across the top of a shelf, two side arms that extend perpendicularly from the opposing short edges of the top face and extend across the shelf sides for the thickness of the shelf, and two return flanges that extend perpendicularly from the bottom edge of the side arms so as to extend partially along the bottom face of the shelf. However, it has a blade support socket 46 extending vertically upward from its top face. This socket 46 has a vertical pass through opening 48 and is conformed to match the horizontal cross sectional configuration of the vertically corrugated fixed blade 44. On either side of the socket is a footer recess 50. At the right and left ends of the socket 46 at the end of the pass through opening 48 are stabilizing grooves 60 that are matingly conformed to the stabilizing ridges 62 formed along the vertical edges of the fixed height blade 44. There are a series of stabilizing gusset tabs 52 spanning between the exterior vertical sides of the blade support socket 46 and the horizontal face of the blade support shelf bracket 42 to increase the rigidity of the socket 46.

(27) The fixed height blade 44 is made in a variety of heights although each blade has the same footprint. The fixed height blade 44 has a pair of parallel vertical spring tabs 54 formed therein. (Although it is known that in alternate embodiments only one spring tab may be used.) These tabs have a normal position (a thermoplastic set) that lies outside of the vertical plane of the section of corrugation that they reside in. The fixed height blade 44 also has a pair of horizontal footers 56 extending perpendicularly from its front and back bottom edges.

(28) In operation, the top end of the fixed height blade is inserted through the socket 46 such that the stabilizing ridges 62 slide through the stabilizing grooves 60 and the horizontal footers 56 on the bottom of the fixed height blade 44 contact the footer recess 50 of the socket 46. At this vertical elevation, the spring tabs 54 of the fixed height blade 44 should extend outward so that their bottom edge contact the top edge of the socket 46, thereby locking the fixed height blade 44 into the blade support shelf bracket 42.

(29) FIGS. 10 to 13 illustrate incremental blade shelf divider 70 (third embodiment shelf divider) in its unassembled and assembled states. The incremental blade shelf divider 70 has at least one upper fixed blade 72 that may be added to extend vertically from a support blade assembly 74. The support blade assembly 74 has a slidingly adjustable horizontal shelf bracket 76 identical to that of the preferred embodiment and a bottom blade 78 extending perpendicularly therefrom its top face. The bottom blade 78 and upper fixed blade 72 are both corrugated and have alternating series of vertical ridges and grooves and arrays of open cells formed there through. The height adjustment on this shelf divider is accomplished by sliding the bottom edge of the additive upper fixed blade 72 onto the top edge of the bottom blade 78 of the support blade assembly 74.

(30) The slidingly adjustable horizontal shelf bracket 76 of the support blade assembly 74 is a C shaped bracket that has a top face that spans across the top of a shelf, two side arms that extend perpendicularly from the opposing short edges of the top face and extend across the shelf sides for the thickness of the shelf, and two return flanges that extend perpendicularly from the bottom edge of the side arms so as to extend partially along the bottom face of the shelf. In this fashion, the support blade base assembly 74 curves around a matingly conformed shelf, and holds the lower blade 10 perpendicular to the top surface of the shelf.

(31) The top edge of the bottom blade has a horizontal, T shaped linear channel 80 traversing across its length (as does the top edge of the upper fixed blade). The bottom edge of the upper fixed blade 72 has a series of alternating connection tabs 82 matingly conformed to alternately engage the two sides of the T shaped linear channel 80. At one end of the linear channel 80 is a locking orifice 86 that is engaged by a lock protrusion 84 formed on one of the alternating connection tabs 82 to secure the horizontal location of the two blades relative to each other. Since the top edge of the upper fixed blade 72 also has the T shaped liner channel 80, multiple upper fixed blades 72 may be connected together to increase the vertical height of the shelf divider.

(32) Each of the three embodiments of the horizontally and vertically adjustable shelf divider present low cost but different approaches to improving the efficiency of storing merchandise on commercially available shelves.

(33) While certain features and aspects have been described with respect to exemplary embodiments, one skilled in the art will recognize that numerous modifications are possible. Moreover, system components described according to a particular structural architecture and/or with respect to one system may be organized in alternative structural architectures and/or incorporated within other described systems.
