FIELD

[0001] The present disclosure relates generally to product shelf displays, and more particularly to a product shelf display including a translatable divider and/or pusher.

BACKGROUND

[0002] This section provides background information related to the present disclosure and is not necessarily prior art.

[0003] Products in a commercial setting, such as a store, may be displayed in a variety of ways. For example, a series of shelving units may be used to stock and display the products. The products may be arranged in columns and rows, with products of the same type arranged in a column behind one another and products of different types arranged in a row next to each other. When the first product in a column is selected and removed from the shelf, the second product in the column may be moved to the first product’s position to occupy the void left by the removal of the first product. Products in adjacent columns may have different sizes (e.g., widths). Moveable dividers and pushers may be used to ensure that products in arranged in rows and columns are maintained in close proximity to one another when the first product in a column is removed and when products of different types are placed and arranged in rows next to each other.

SUMMARY

[0004] This section provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features.

[0005] An aspect of the disclosure provides an example of a retail management system including a carriage base and an engagement mechanism. The carriage base includes a first end defining a front surface and a second end formed at an opposite end from the first end. The engagement mechanism is disposed at the first end of the carriage base and includes a plurality of carriage teeth extending from the front surface, the plurality of carriage teeth including at least one primary carriage tooth having a first configuration and at least one secondary carriage tooth having a second configuration that is different than the first configuration. [0006] This aspect of the disclosure may include one or more of the following optional features. In some examples, the first size is a first length measured from the front surface to a distal end of the primary carriage tooth and the second size is a second length measured from the front surface to a distal end of the secondary carriage tooth. In some configurations, each of the carriage teeth includes a top end defining a substantially planar surface perpendicular to the front surface.

[0007] In some implementations, each of the carriage teeth has a first height extending along the front surface from a bottom end to a top end and includes a lower biasing surface formed adjacent to the bottom end. In some examples, the lower biasing surface extends at an oblique angle relative to the front surface of the carriage base. In some implementations, the lower biasing surface includes an arcuate portion immediately adjacent to the bottom end. In some configurations, the lower biasing surface has a second height that is at least half of the first height. In some configurations, each of the carriage teeth includes an arcuate peripheral side surface extending between the bottom end and the top end.

[0008] In some examples, the engagement mechanism is operable between a retracted position and an extended position relative to the front surface of the carriage base. In some configurations, the engagement mechanism is integrally formed with the front surface of the carriage base.

[0009] In some implementations, the engagement mechanism is a carriage engagement mechanism, and wherein the system further includes a rail. Optionally, the rail includes a rail engagement mechanism operable to move between a first configuration and a second configuration. In some implementations, the rail includes a frame and the rail engagement mechanism is attached to the frame and operable to move a first configuration and the second configuration.

[0010] In some examples, the rail engagement mechanism includes a plurality of rail teeth configured to move relative to the frame. In some implementations, each of the plurality of the rail teeth is coupled to the frame by a resilient member including a different material than the frame. In some examples, each of the plurality of the rail teeth is integrally formed with the resilient member. In some implementations, the rail engagement mechanism includes a flexible front wall attached to the resilient member and the plurality of rail teeth extend from the front wall. In some examples, the resilient member includes a strip of a first material disposed between the frame and the rail engagement mechanism, the first material having a lower durometer than a second material forming the frame or the rail engagement mechanism. [0011] Another aspect of the disclosure provides examples of an engagement mechanism for a retail management system including a rail. In some examples, the engagement mechanism includes a biasing element including a first end and a second end formed on an opposite side of the biasing element from the first end, and a first engagement element disposed at the first end of the biasing element that has a front surface having a plurality of teeth including at least one primary tooth having a first configuration and at least one secondary tooth having a second configuration different than the first configuration.

[0012] This aspect of the disclosure may include one or more of the following optional features. In some examples, the engagement mechanism includes a second engagement element disposed at the second end of the biasing element and defining an elongate track configured to slidably receive the rail. In some implementations, the second engagement element includes an engagement feature configured to slidably secure the engagement mechanism to the rail. In some configurations, the biasing element is configures a resilient biasing element operable between compressed configuration having a first length between the first end and the second end and a relaxed configuration having a second length between the first end and the second end that is greater than the first length. In the compressed configuration, the biasing element applies a biasing force to at least one of the first engagement element and the second engagement element.

[0013] Further areas of applicability will become apparent from the description provided herein. The description and specific examples in this summary are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.

DETAILED DESCRIPTION

[0042] Example configurations will now be described more fully with reference to the accompanying drawings. Example configurations are provided so that this disclosure will be thorough, and will fully convey the scope of the disclosure to those of ordinary skill in the art. Specific details are set forth such as examples of specific components, devices, and methods, to provide a thorough understanding of configurations of the present disclosure. It will be apparent to those of ordinary skill in the art that specific details need not be employed, that example configurations may be embodied in many different forms, and that the specific details and the example configurations should not be construed to limit the scope of the disclosure.

[0043] The terminology used herein is for the purpose of describing particular exemplary configurations only and is not intended to be limiting. As used herein, the singular articles “a,” “an,” and “the” may be intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “comprising,” “including,” and “having,” are inclusive and therefore specify the presence of features, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and/or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order discussed or illustrated, unless specifically identified as an order of performance. Additional or alternative steps may be employed.

[0044] When an element or layer is referred to as being “on,” “engaged to,” “connected to,” “attached to,” or “coupled to” another element or layer, it may be directly on, engaged, connected, attached, or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to,” “directly connected to,” “directly attached to,” or “directly coupled to” another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

[0045] The terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections. These elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as “first,” “second,” and other numerical terms do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example configurations.

[0046] Referring to FIG. 1, a product management system 10 is generally shown. The product management system 10 may be disposed on a shelf (not shown) or other suitable supporting device, and may include a rail 12, a carriage assembly 14, and, in some implementations, a pusher (not shown). For the sake of describing the features of the disclosure, the product management system and components thereof may be described in terms of a first axis or direction Di that extends generally along a lateral direction corresponding to the length of the rail 12, a second axis or direction D2 that extends generally perpendicular to the first direction Di and along a longitudinal direction of the carriage assembly 14, and a third axis or direction D3 corresponding to a vertical direction extending perpendicular to each of the first direction Di and the second direction D2.

[0047] The rail 12 extends in the first direction Di. The carriage assembly 14 extends in a second direction D2 perpendicular to the first direction Di and is coupled to the rail 12 for translation in the first direction Di. Specifically, the rail 12 includes a rail engagement mechanism 16 and the carriage assembly 14 includes a carriage engagement mechanism 18 configured to engage with the rail engagement mechanism 16. The engagement mechanisms 16, 18 may be configured to enable the carriage assembly 14 to selectively translate along the rail 12 in the first direction Di.

[0048] In some implementations, the engagement mechanisms 16, 18 may enable the carriage assembly 14 to selectively translate along the rail 12 in the first direction Di without the use of a manual engagement actuator, such as a button, switch, etc., for selectively engaging and disengaging the carriage assembly 14 with the rail 12. By eliminating the need for a manual actuator, the product management system 10 may reduce the number of components, thus, reducing weight, cost, and materials. Further, the means for translating the carriage assembly 14 along the rail 12 may be simplified compared to a manual actuator, and such a configuration eliminates the confusion as to whether the carriage assembly 14 is engaged with or disengaged from the rail 12, thus, reducing the risk of damage incurred by the product management system 10.

[0049] Referring to FIGS. 1 and 2, the rail 12 may be configured to be placed on a shelf (not shown) or other suitable surface of a store or other suitable location. For example, the rail 12 may include a generally flat bottom surface. In some implementations, the rail 12 may include feet or gripping members (not shown) to reduce friction between the rail and the shelf. In other implementations, the rail 12 may be secured to the shelf in any suitable manner, such as, for example, mechanical fasteners, adhesive, welding, etc. While the product management system 10 is shown in FIG. 1 as including one rail 12 and one carriage assembly 14, it should be understood that any suitable number of these components may be implemented, including an optional pusher (not shown).

[0050] The rail 12 may have a generally U-shaped cross-section including a front wall 26, a rear wall 28, and a base 30 connecting the front wall 26 to the rear wall 28. The front wall 26, the rear wall 28, and the base 30 cooperate to define a channel 32 configured to receive a portion of the carriage assembly 14 and a portion of the pusher. The front wall 26 may include the rail engagement mechanism 16. For example, the rail engagement mechanism 16 may be attached to or integrally formed with the front wall 26. In other implementations, the rail engagement mechanism 16 may be located at any suitable location on the rail 12. In some implementations, the rail engagement mechanism 16 includes an upper flange 50 formed at a distal end of the front wall 26 and a plurality of rail teeth 52 each extending between the upper flange 50 and the base 30, whereby the rail teeth 52 arranged in series along the front wall 26 in the first direction Di. In other implementations, the rail engagement mechanism 16 may be any suitable engagement mechanism, such as, for example, a mechanical fastener, a magnet, an electromagnet, a hook-and- loop fastener, a high-friction material, etc.

[0051] Referring to FIGS. 1 and 2, the carriage assembly 14 extends from the front portion 20 to the rear portion 22. As used herein, the term “front” generally refers to the portion of the carriage assembly 14 that would be facing prospective customers or an aisle in a store and the term “rear” generally refers to the portion of the carriage assembly 14 that is furthest from prospective customers or an aisle in a store. In some implementations, as shown in FIG. 1, the front portion 20 of the carriage assembly 14 may engage the rail 12, i.e., be received in the channel 32. In other implementations, the rail 12 may be disposed entirely between the front portion 20 and the rear portion 22 of the carriage assembly 14. While the rail 12 is shown as being disposed closer to the front portion 20 than the rear portion 22, in some implementations, the rail 12 may be disposed closer to the rear portion 22 than the front portion 20 or disposed equidistant from (e.g., centrally located between) the front portion 20 and the rear portion 22.

[0052] The carriage assembly 14 includes a carriage base 34, a dividing wall 36 attached to the carriage base 34, and a front stopper 38. The carriage base 34 and the dividing wall 36 generally extend from the front portion 20 to the rear portion 22, while the stopper 38 is disposed at or near the front portion 20 to cooperate with a pusher (not shown) to hold products in place. The carriage base 34 includes a top surface configured to receive and support products. In some implementations, the carriage base 34 includes a slot 46 for receiving the rear wall 28 of the rail 12.

[0053] Referring to FIGS. 3 and 6, the carriage assembly 14 may include the carriage engagement mechanism 18 at or near the front portion 20. For example, the carriage engagement mechanism 18 is disposed in a cavity 35 formed in a bottom side of the carriage base 34 at the front portion 20. In the illustrated example, the carriage engagement mechanism 18 includes a biasing element 37 disposed within the cavity 35, a front engagement element 39 attached to a first end of the biasing element 37 and disposed below the stopper 38 in the front portion 20 of the carriage assembly 14, and a rear engagement element 41 attached to an second end of the biasing element 37. Thus, the front engagement element 39 and the rear engagement element 41 are disposed on opposite ends of the biasing element 37 such that the biasing element 37 is configured to bias the front engagement element 39 apart from the rear engagement element 41. In other implementations, the carriage engagement mechanism 18 is disposed at any suitable location on the carriage assembly 14. The carriage engagement mechanism 18 may include a plurality of carriage teeth 54. During operation, the rail engagement mechanism 16 may be selectively engaged by the front engagement element 39 of the carriage engagement mechanism 18, as shown in FIGS. 1, 2, and 7. For example, as shown, the plurality of rail teeth 52 may be configured to be selectively engaged by the plurality of carriage teeth 54. In other implementations, the carriage engagement mechanism 18 may include any suitable engagement mechanism, such as, for example, a mechanical fastener, a magnet, an electromagnet, a hook-and-loop fastener, a high- friction material, etc. configured to selectively engage the rail engagement mechanism 16.

[0054] Referring to FIGS. 5-7, the carriage teeth 54 of the carriage engagement mechanism 18 may be generally low-profile relative to the rail teeth 52 of the rail engagement mechanism 16. For example, the carriage teeth 54 may have a height H54 relative to a base surface 53 that is less than a depth D52 between each of the rail teeth 52. In some implementations, the rail teeth 52 define a first cross-sectional shape extending in a plane substantially parallel to the depth D52, while the carriage teeth 54 define a second cross-sectional shape extending in a plane substantially parallel to the height H54. The first cross-sectional shape may be different than the second cross- sectional shape. For example, the first cross-sectional shape may define a substantially convex or semi-cylindrical configuration, while the second cross-sectional shape may define a substantially V-shaped, triangular, or frustoconical configuration, or vice versa. In some implementations, the rail teeth 52 include a pair of planar sidewalls defining a first cross-sectional shape, and the carriage teeth 54 include a pair of planar sidewalls defining the second cross-sectional shape. The sidewalls of the rail teeth 52 may define a first angle therebetween, and the sidewalls of the carriage teeth 54 may define a second angle therebetween. The value of the first angle may be different than the value of the second angle. For example, the first angle may be substantially equal to zero degrees, such that the sidewalls of the rail teeth 52 are substantially equal to one another, while the second angle may be between five degrees and one hundred seventy-five degrees, such that the sidewalls of the carriage teeth 54 are transverse to one another. In some implementations, the angle between the sidewalls of the second cross-sectional shape is substantially equal to ninety degrees.

[0055] In some implementations, the carriage teeth 54 may include a relatively soft resilient material having a lower durometer or modulus of elasticity than a material forming the base surface 53, whereby the carriage teeth may flex relative to the base surface 53 in response to a force, i.e., flex toward and away from the base surface 53. In other implementations, the rail teeth 52 may include the soft resilient material such that the rail teeth may flex relative to the front wall 26 of the rail 12 in response to a force. In other implementations still, both the rail teeth 52 and the carriage teeth 54 may include of the soft reseilient material such that they both flex in response to a force. The height H54 of the carriage teeth 54 may be high enough to prohibit transverse movement of the carriage assembly 14 along the rail 12 in the first direction Di by causing engagement, or contact, between the rail teeth 52 and the carriage teeth 54, however, the height H54 of the carriage teeth 54 may be low enough to allow the carriage assembly 14 to translate along the rail 12 in the first direction Di after a force exerted upon the carriage assembly 14 in the first direction Di is sufficient to overcome the engagement, or contact, between the rail teeth 52 and the carriage teeth 54. In this regard, the arrangement of the first and carriage teeth 52, 54 (e.g., the first and second cross-sectional shapes, the angles defined by the respective sidewalls, the height H54 and depth D52, etc.) may allow the rail teeth 52 to be disposed in a void between adjacent ones of the carriage teeth 54, and vice versa, without the distal ends of the carriage teeth 54 engaging a portion of the front wall 26 disposed between such adjacent rail teeth 52, and/or without the distal ends of the rail teeth 52 engaging the base surface 53.

[0056] Referring to FIGS. 3 and 4 and FIG. 12 (where the carriage engagement mechanism 18 is illustrated in connection with a second example of a carriage assembly 14a), the carriage engagement mechanism 18 includes several elements to maintain alignment or orientation of the carriage engagement mechanism 18 during use. For example, the carriage assembly 14 may include a wall engagement feature 42 and one or more stabilizers 45. As best shown in FIG. 3, the wall engagement feature 42 of the carriage assembly 14 may be integrated into the rear engagement element 41 of the carriage engagement mechanism 18. Particularly, the wall engagement feature 42 may be spaced apart from the second end of the biasing element 47 to define a groove or rear track 43 between the wall engagement feature 42 and the second end of the biasing element 37.

[0057] As shown in FIG. 4, the rear track 43 of carriage engagement mechanism 18 is configured to receive a portion of the rear wall 28 of the rail 12 when the carriage assembly 14 is assembled to the rail 12. In other words, the rear track 43 is aligned with the slot 46 of the carriage base 34 to provide a continuous channel extending across the width of the carriage assembly 14 in the second direction D2. Thus, the rear track 43 of the carriage engagement mechanism 18 and the slot 46 of the carriage base 34 cooperate to each receive a portion of the rear wall 28 of the rail 12. [0058] The wall engagement feature 42 may be configured to slidably engage the rear wall 28 of the rail 12 to secure the carriage engagement mechanism 18 (and the carriage assembly 14) onto the rear wall 28. In this regard, the rear wall 28 may define a groove 60 extending in the first direction Di along the length of the rail 12. In an assembled configuration, the wall engagement feature 42 may be translatably disposed within the groove 60, while the carriage base 34 of the carriage assembly 14 may be translatably disposed within the channel 32 of the rail 12. That is, the wall engagement feature 42 may allow the carriage assembly 14 and the carriage engagement mechanism 18 to translate (e.g., slide) along the first direction Di, while inhibiting separation of the carriage assembly 14 from the rail 12 in a vertical direction D3 (e.g., a direction perpendicular to the first and second directions Di, D2). Providing the interface between the rear wall 28 of the rail 12 and the rear track 43 of the carriage engagement mechanism 18 functions to maintain the orientation of carriage engagement mechanism 18 relative to the rail 12 when the carriage assembly 14 is translated along the rail 12. For example, when the carriage assembly 14 is translated along the rail 12 without fully disengaging the carriage teeth 54 from the rail teeth 52, the interference between the teeth 52, 54 may create a counteractive force on the front engagement element 39 in a direction opposing the direction of translation. This counteractive force may include a torsional force component that causes the carriage engagement mechanism 18 to rotate within the cavity 35. However, by providing the interface between the rear wall 28 and the rear track 43, rotation of the carriage engagement mechanism 18 is minimized to maintain alignment between the rail teeth 52 and the carriage teeth 54.

[0059] In addition to the rear engagement element 41, the carriage engagement mechanism 18 may include a pair of the stabilizers 45 disposed at the first end of the biasing element 37. Each of the stabilizers 45 extends outwardly to a distal end that engages a front wall portion of the carriage base 34 of the carriage assembly 14. The stabilizers 45 function as both (i) a positive stop to prevent over-extension of the biasing element 37 and the front engagement element 39 and (ii) as alignment aids to maintain a rotational orientation of the carriage engagement mechanism 18 relative to the carriage base 34.

[0060] With reference to FIGS. 1 and 2, the carriage assembly 14 may include a pair of gripping members 44 disposed at or near the front portion 20. The gripping members 44 may be defined by generally arcuate or concave cutouts or voids disposed on opposite sides of the stopper 38. In some implementations, the gripping members include a plurality of ridges, a high-friction material, or any other suitable gripping member 44. The gripping members 44 may facilitate pushing and pulling of the carriage assembly 14 along the first direction Di by allowing a user’s fingers to comfortably and efficiently engage opposite side of the stopper 38.

[0061] In some implementations, the pusher extends in the second direction D2 and is coupled to the rail 12 in a manner substantially similar to the carriage assembly 14 (i.e., via the carriage base 34) or in any suitable manner. Likewise, the pusher may include a third engagement mechanism substantially similar to the carriage engagement mechanism 18, such that the pusher is selectively translatable long the rail 12 in the first direction Di similar to the carriage assembly 14. Alternatively, the pusher may translate along the rail 12 in any suitable manner, e.g., sliding freely along the rail 12, or may be fixed to the rail 12.

[0062] The components of the product management system 10, i.e., the rail 12, the carriage assembly 14, and the pusher, and associated components thereof, may be formed of any suitable material(s). These components may be formed of the same material, different materials, or some combination of the two. For example, these components may be formed of a plastic, a metal, carbon fiber, etc. These components may be formed by or implementing any suitable process, such as, for example, injection molding, 3-D printing, welding, gluing, mechanical fastening, etc. [0063] As set forth above, the product management system 10 may be implemented on a shelf or other suitable surface of a store or any suitable storage location. For example, two carriage assemblies 14 may be spaced from each other, and a pusher may be disposed between the two carriage assemblies 14, such that the carriage assemblies 14 and/or pusher can be translated along the rail 12 to allow products to be inserted into the product management system 10. For example, wide products may require the carriage assemblies 14 to be translated along the rail 12 in the first direction Di away from each other, and narrow products may require the carriage assemblies 14 to be translated along the rail 12 in the first direction Di toward each other. To translate the carriage assembly 14, a user may grasp the carriage assembly 14, for example at the gripping members 44, and push or pull the carriage assembly 14 along the first direction Di. The engagement of the rail teeth 52 and the carriage teeth 54 may initially resist movement of the carriage assembly 14 along the rail 12. However, upon the user exerting a sufficient force upon the carriage assembly 14, the teeth 52, 54, and/or any other suitable component of the rail 12 and/or the carriage assembly 14, may briefly flex to allow the divider to translate along the rail 12, i.e., until one of the carriage teeth 54 engages with an adjacent one of the rail teeth 52. After flexing, the teeth 52, 54, and/or any other suitable component of the rail 12 and/or the carriage assembly 14, may return to their natural state to again inhibit movement of the carriage assembly 14 along the rail 12. Then, the foregoing process may repeat. In real-time, the foregoing process may occur relatively quickly such that the carriage assembly 14 may translate along the rail 12 in a relatively continuous or fluid manner. Alternatively, the carriage teeth 54 may engage with the rail teeth 52 such that the movement of the carriage assembly 14 is jerky or choppy, with each one of the carriage teeth 54 sequentially engaging with each adjacent tooth of the rail teeth 52, e.g., similar to a ratcheting mechanism.

[0064] Referring now to FIGS. 8-12, another carriage assembly 14a for use with the rail 12 and/or a pusher (not shown) is provided. In view of the substantial similarity in structure and function of the components associated with the carriage assembly 14a relative to the carriage assembly 14, like reference numerals are used hereinafter and in the drawings to identify like components while like reference numerals containing letter extensions are used to identify those components that have been modified.

[0065] With reference to FIG. 10, the carriage assembly 14a may extend in the second direction D2 perpendicular to the first direction Di and may be coupled to the rail 12 for translation in the first direction Di. Specifically, the rail 12 includes the rail engagement mechanism 16 and the carriage assembly 14a includes the carriage engagement mechanism 18 (FIGS. 11-12) configured to engage with the rail engagement mechanism 16. The engagement mechanisms 16, 18 may be configured to enable the carriage assembly 14a to selectively translate along the rail 12 in the first direction Di.

[0066] The carriage assembly 14a further includes the carriage base 34, the dividing wall 36, and a stopper 38a. The dividing wall 36 may include a first side surface 62 and a second side surface 64 opposite the first side surface 62. In some implementations the first side surface 62 is substantially (e.g., +/- 5 degrees) parallel to the second side surface 64. In this regard, the first and second side surfaces 62, 64 may extend in the same direction. For example, in the assembled configuration (e.g., FIG. 1), the first and second side surfaces 62, 64 may extend in the second direction D2. In some implementations, the first side surface 62 and/or the second side surface 64 is substantially planar.

[0067] The stopper 38a is disposed at or near the front portion 20 to cooperate with the pusher to hold products in place. The stopper 38a may include a front surface 66, a rear surface 68 opposite the front surface 66, the pair of gripping members 44, and a flange 70 disposed at or near the front portion 20. The gripping members 44 may each include an arcuate flange 71 extending from the front surface 66 of the stopper 38a.

[0068] The flange 70 may include a bottom end 72, a top end 74 opposite the bottom end 72, a rear end 76 extending between the bottom and top ends 72, 74, a front end 78 opposite the rear end 76 and extending between the bottom and top ends 72, 74, a first lateral side 80 extending between the bottom, top, rear, and front ends 72, 74, 76, 78, and a second lateral side 82 opposite the first lateral side and extending between the bottom, top, rear, and front ends 72, 74, 76, 78. At least one of the top and front ends 74, 78 may include an arcuate portion 84. For example, the arcuate portion 84 may define a radius of curvature extending from the top end 74 and the front end 78. In some implementations, the top end 74 and/or the front end 78 may extend tangentially from the arcuate portion 84 to provide improved comfort and maneuverability by the user applying a force on the flange 70. In some implementations the bottom end 72 extends from, and is coplanar with, a lower edge 86 of the stopper 38a to improve coupling of the carriage assembly 14a to the rail 12 in the assembled configuration.

[0069] The first and second lateral sides 80, 82 may extend from the stopper 38a (e.g., the front surface 66) in a direction transverse to the first direction Di. In some implementations, the first and/or second lateral sides 80, 82 define a planar configuration extending from the stopper 38a in a direction substantially (e.g., +/- 5 degrees) perpendicular to the first direction Di and substantially (e.g., +/- 5 degrees) parallel to the second direction D2. During use, to translate the carriage assembly 14a relative to the rail 12, a user may grasp the carriage assembly 14a and push or pull the carriage assembly 14a along the first direction Di. The configuration of the flange 70 (e.g., the first and second lateral sides 80, 82) can allow a user to more easily grasp the carriage assembly 14a and apply a force in a direction transverse to the second direction D2, thus allowing the user to adjust the position of the carriage assembly 14a relative to the rail 12, as previously described. In particular, the configuration of the flange 70 can allow the user to translate the carriage assembly 14a in the first direction Di without causing the carriage assembly 14a to rotate relative to the first and/or second direction Di, D2.

[0070] Referring now to FIGS. 13-20, another carriage assembly 14b for use with the rail 12 and/or a pusher (not shown) is provided. In view of the substantial similarity in structure and function of the components associated with the carriage assembly 14b relative to the carriage assembly 14, like reference numerals are used hereinafter and in the drawings to identify like components while like reference numerals containing letter extensions are used to identify those components that have been modified.

[0071] With reference to FIG. 13, the carriage assembly 14b includes a carriage base 34b having a carriage engagement mechanism 18b (FIGS. 15-20) configured to engage with the rail engagement mechanism 16 of the rail 12 shown in FIGS. 1-3. The engagement mechanisms 16, 18b may be configured to enable the carriage assembly 14b to selectively translate along the rail 12 in the first direction Di without actively disengaging the carriage engagement mechanism 18b from the rail engagement mechanism 16. In other words, the carriage engagement mechanism 18b is configured such that a user can translate the carriage assembly 14b along the rail 12 by applying a lateral translation force Fi (i.e., in the first direction Di), whereby the carriage engagement mechanism 18b remains partially engaged with the rail engagement mechanism 16 during the movement to provide a desired resistance force F R i n an opposite direction of the lateral translation force Fi. This feature is described in greater detail below with respect to the configuration of the carriage engagement mechanism 18b.

[0072] The carriage assembly 14b further includes the carriage base 34b, the dividing wall 36, and the front stopper 38. The front stopper 38 is disposed at or near the front portion 20 to cooperate with the pusher to hold products in place. The front stopper 38 may include a front surface 66b, arear surface 68b opposite the front surface 66b, and a pair of gripping members 44. In this example, the gripping members 44 include a pair of arcuate ribs 44 extending from the front surface 66b of the stopper 38b. While not shown in the illustrated example, the stopper 38 may optionally include the flange 70 described previously with respect to FIGS. 8-12. Optionally, the carriage assembly 14b may include a rear stopper 38b attached to the carriage base 34b and/or the divider wall 36 between the front portion 20 and the rear portion 22 of the carriage assembly 14b. The rear stopper 38b includes a panel or protrusion attached to the carriage base 34b and/or the divider wall 36 and is configured to obstruct a product receiving area of the product management system 10, thereby preventing products loaded into the product management system 10 from being pushed beyond the rear portion 22 of the carriage assembly. In some examples, a position of the rear stopper 38b may be adjusted along the second direction D2 to provide the product receiving area of the product management system 10 with a desired depth (i.e., distance measured from the front portion 20 along the second direction D2).

[0073] With reference to FIGS. 15-20, the carriage engagement mechanism 18b of the present example is substantially similar to the carriage engagement mechanism 18 set forth above. Thus, the carriage engagement mechanism 18b includes the biasing element 37, a front engagement element 39b defining a plurality of carriage teeth 54b, 54c, the rear engagement element 41 including the wall engagement feature 42 and the rear track 43. [0074] Referring to FIGS. 18-20, the carriage engagement mechanism 18b of this example is provided with primary carriage teeth 54b and secondary carriage teeth 54c, as discussed below. Generally, each of the carriage teeth 54b, 54c has a height H54 that extends from a top end 55b, 55c to a bottom end 56 along a third direction D3 that generally corresponds to a vertical direction perpendicular to each of the first direction Di and the second direction D2. The primary carriage teeth 54b have a different configuration (e.g., size, shape, material) than the secondary carriage teeth 54c to provide the primary carriage teeth 54b with different operating characteristics than the secondary carriage teeth 54c. For example, the primary carriage teeth 54b may be configured to provide greater engagement with the rail in one or both of the lateral direction Di or the vertical direction D2.

[0075] The top end 55b, 55c of each carriage tooth 54b, 54c defines a generally horizontal surface (i.e., extending in the plane of Di and D2) that extends perpendicular from a front surface of the carriage base 34. The top end 55b, 55c of each carriage tooth 54b, 54c is configured to interface with an upper flange 50 of the rail 12 when the carriage assembly 14b is installed on the rail 12 to prevent inadvertent disengagement of the carriage assembly 14b from the rail 12 in the vertical direction D3. The interface between the top ends 55b, 55c of the carriage teeth 54b, 54c and the upper flange 50 of front wall 26 provides both vertical retention and torsional stability to the front portion of the carriage assembly 14b.

[0076] As best shown in FIG. 19, each of the carriage teeth 54b, 54c further includes a peripheral side surface 57b, 57c extending from the top end 55b, 55c to the bottom end 56 and defining a peripheral profile of the carriage teeth 54b, 54c. In the illustrated example, the peripheral side surface 57b, 57c of each tooth is semi-cylindrical in shape and defines a convex peripheral profile of each tooth 54b, 54c relative to the front surface 40 of the front engagement element 39b. While the illustrated example provides a semi-cylindrical peripheral side surface 57, the peripheral side surface 57b, 57c may also be polygonal in shape. With reference to FIG. 20, the peripheral side surface 57b, 57c defines a length L54b, L54C and width W54 of each carriage tooth 54b, 54c. Here, the lengths L54b, L54C are measured as a distance from the front surface 40 to a distal end or apex of the carriage tooth 54b, 54c (i.e., along the second direction D2) while the width W54 is measured from a first side of the carriage tooth 54b, 54c to a second side of the carriage tooth 54b, 54c (i.e., along the first direction Di). Optionally, the carriage teeth 54b, 54c may be provided as primary carriage teeth 54b having a first length Ls4b and secondary carriage teeth 54c having a second length Ls4cthat is less than the first length Ls4b. Here, the primary carriage teeth 54b extend a greater distance from a front surface 40 of the front engagement element 39 than the secondary carriage teeth 54c. Thus, the upper surfaces defined by the top ends 55b of the primary carriage teeth 54b is larger and extends farther into the rail engagement mechanism 16 than the upper surfaces defined by the shorter top ends 55c of the secondary carriage teeth 54c.

[0077] The primary carriage teeth 54b and the secondary carriage teeth 54c cooperate to facilitate the desired balance of stability and adjustability. For instance, the longer primary carriage teeth 54b provide a greater interface with the upper flange 50 of the rail engagement mechanism (i.e., vertical and torsional stability) while the shorter secondary carriage teeth 54c provide reduced lateral resistance, allowing the carriage assembly 14b to be laterally translated along the rail 12 by applying the translation force Fl to the gripping members 44. While the illustrated example shows the primary carriage teeth 54b and the secondary carriage teeth 54c arranged in a repeating pattern of one secondary carriage tooth 54c and two primary carriage teeth 54b along the front surface 40 of the front engagement element 39, the front engagement element 39 may include any number or arrangement of the primary carriage teeth 54b and the secondary carriage teeth 54c to provide a desired balance of vertical stability and lateral adjustability.

[0078] Optionally, one or more of the carriage teeth 54b, 54c may further include a lower biasing surface extending from the bottom end 56. Here, the lower biasing surface 58 is formed as a substantially planar surface oriented at an oblique angle relative to the front surface 40 of the front engagement element 39, such that lengths of each of the carriage teeth 54b, 54c increase along a direction from the bottom end 56 to the top end 55. As shown, the lower biasing surfaces 58 of the primary carriage teeth 54b and the secondary carriage teeth 54c extend at the same angle. Optionally, the lower biasing surface 58 may include an arcuate or convex portion formed immediately adjacent to the bottom end 56. In use, the lower biasing surface 58 surfaces as ramp for engaging the carriage engagement mechanism 18b with the rail engagement mechanism 16. Specifically, as the front portion 20 of the carriage assembly 14b is lowered into the rail 12, the lower biasing surface 58 engages the upper flange 50 of the front wall 26 and biases the front engagement element 39 of the carriage engagement mechanism 18b into a retracted state (i.e., the carriage teeth 54b, 54c are retracted into the cavity 35). Once the carriage teeth 54b, 54c are fully engaged with the rail engagement mechanism 16, the biasing element 37 moves the front engagement element 39 back to the extended state so that the carriage teeth 54b, 54c are engaged below the upper flange 50. Thus, the lower biasing surfaces 58 allow the carriage assembly 14b to be engaged (i.e., snapped into) with the rail 12 without manually moving the carriage engagement mechanism 18b between the extended and retracted positions (i.e., without using a manual button or actuator).

[0079] Referring to FIG. 17, the carriage engagement mechanism 18b may be provided with one or more adjustment inserts 48 configured to interface with the biasing element 37 to modify or adjust the stiffness of the biasing element 37. For example, the rail engagement mechanism 16b may include removable adjustment inserts 48 having different wall thicknesses or material properties to define different levels of stiffness. In the illustrated example, the adjustment inserts 48 are embodied as insert rings 48 that can be received within the annular body of the biasing element 37. A user may replace or supplement adjustment inserts 48 as desired based on the type of product being stocked on the product management system. For example, heavier products may require a relatively stiff adjustment insert 48 to minimize inadvertent disengagement or translation of the carriage assembly 14b, while lighter products may require a relatively compliant adjustment insert 48 or no adjustment insert to allow the carriage assembly 14b to be easily adjusted.

[0080] Referring now to FIGS. 21-26, another product management assembly 10c including a carriage assembly 14c for use with a rail 12c and/or a pusher (not shown) is provided. In view of the substantial similarity in structure and function of the components associated with the carriage assembly 14c relative to the carriage assembly 14, like reference numerals are used hereinafter and in the drawings to identify like components while like reference numerals containing letter extensions are used to identify those components that have been modified.

[0081] In this example, the rail 12c is provided with a resilient or dynamic rail engagement mechanism 16c while the carriage base 34 of the carriage assembly 14c is provided with a stationary or static carriage engagement mechanism 18c. Here, the carriage engagement mechanism 18c may be formed as an integral part of the carriage assembly 14c, whereby the carriage teeth 54-54c are formed directly on a front surface of the divider. The carriage teeth 54- 54c may have any of the configurations discussed above.

[0082] As best shown in FIGS. 23-26, the rail 12c may be described as including a frame 90, the rail engagement mechanism 16c, and a resilient member 92 attaching the rail engagement mechanism 16c to the frame 90. Here, the frame 90 is part of the front wall 26c of the rail 12 and includes a front sidewall 94 and the upper flange 50 extending from the front sidewall 94 to define a front channel 96. The resilient member is disposed within the front channel 96 and may include a front surface 98 that is attached to a rear surface of the front sidewall 94. The carriage engagement mechanism 16c may also be received within the front channel 96 and attached to a rear surface 100 of the resilient member 92. Particularly, the rail engagement mechanism 16c may include a front wall 102 that attaches to the rear surface 100 of the resilient member 92. The rail teeth 52 extend from a rear surface of the front wall 102 of the rail engagement mechanism 16c. Here, the front wall 102 of the rail engagement mechanism 16c is configured as a flexible member having a relatively high hardness so that the front wall 102 bends along the length of the resilient member 92 as the carriage teeth 54 are translated along the rail teeth in the first direction DI. While the illustrated example shows the rail teeth 52 as extending from the front wall 102 of the rail engagement mechanism 16c, in other examples the rail teeth 52 may directly incorporate the resilient material without the use of a resilient member or may be directly coupled to the resilient member 92. Furthermore, the resilient member 92 may be provided as a unitary element coupled to a plurality of the rail teeth 52, or may include a plurality of independent resilient members 92 each coupled to one or more of the rail teeth 52.

[0083] Optionally, the rail engagement mechanism 16c may define an upper flange 104 and/or an opposite lower flange 106. Here, the upper flange 104 provides an upper engagement interface for the top ends 55b, 55c of the carriage teeth 56b, 56c. One or both of the upper flange 104 and the lower flange 106 may be omitted from the rail engagement mechanism 16c, such that the frame 90 of the rail 12c defines the upper and lower surfaces of the rail engagement mechanism 16c.

[0084] In the illustrated example, the resilient member 92 includes one or more strips of a resilient polymeric material having a lower durometer and greater resilience than the materials of the frame 90 and the rail engagement mechanism 16c. For example, foamed polymers and rubbers are suitable materials. Additionally or alternatively, the resilient member 92 may include a compressible mechanical structure, such as a helical compression spring or a leaf spring disposed between the front sidewall 94 of the frame 90 and the front wall 102 of the rail engagement mechanism 16c.

[0085] The resilient member 92 is configured to provide a biasing force F3 in the second direction to counteract a compressive force F4 applied to the rail engagement mechanism 16c by the carriage teeth 54b, 54c when the carriage assembly 14c is translated along the first direction Di. For example, when a lateral force is applied to the carriage assembly 14c in the first direction Di, the convex carriage teeth 54b, 54c may apply a compressive force to the distal ends of the rail teeth 52 to bias the rail teeth 52 in the second direction D2 towards the front sidewall 94 of the frame 90. Once a desired lateral position is obtained and the carriage teeth 54b, 54c are engaged (i.e., received between) the rail teeth 52, the resilient member 92 biases the rail engagement mechanism 16c in the second direction D2 so that the second rail teeth 52 extend between adjacent ones of the carriage teeth 54. The resilient member 92 and the rail engagement mechanism 16c may be configured so that only a localized portion of the rail engagement mechanism 16c flexes as the carriage assembly 14c is translated. In other words, the rail engagement mechanism 16c may deform or flex in a wave-like manner as the carriage teeth 54b, 54c depress a corresponding portion of the rail engagement mechanism 16c.

[0086] The aforementioned examples of carriage assemblies 14- 14c are configured to provide for an easily adjustable and durable product management system 10, whereby lateral positions of the carriage assemblies 14- 14c can be changed by a user without the use of an actuator for manually engaging and disengaging the rail 12. Instead, the configurations and materials of the rail teeth 52 and/or the carriage teeth 54-54c are designed and selected to allow one or both sets of teeth 52, 54-54c to move or flex relative to the other set of teeth 52, 54-54c in the second direction D2 in response to application of a force in the lateral direction Di. In other words, a lateral force Fl applied to the carriage is translated to a longitudinal force that causes one of the sets of teeth 52, 54-54c to move in the second direction D2 away from the other set of teeth 52, 54-54c, thereby allowing the carriage teeth 54-54c to pass along the rail teeth 52 in the first direction Di.

[0087] While the carriage assemblies 14-14c of the present disclosure are embodied as product dividers including the dividing wall 36 attached to the carriage base 34-34c, the principles of the present disclosure may be applied to carriage assemblies configured for other uses in a product management system. For example, the carriage assemblies 14-14c may be configured to include a dynamic product pusher that is configured to bias a product inventory towards the front portion of the carriage assembly 14-14c, as is known in the art. Such a configuration may be realized by forming a track in or along the top surface of the carriage base 34-34c. Other implementations of the carriage base 34-34c may also be realized without departing from the principles of this disclosure.

[0088] The foregoing description has been provided for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure. Individual elements or features of a particular configuration are generally not limited to that particular configuration, but, where applicable, are interchangeable and can be used in a selected configuration, even if not specifically shown or described. The same may also be varied in many ways. Such variations are not to be regarded as a departure from the disclosure, and all such modifications are intended to be included within the scope of the disclosure.
