[0029] A novel System and Method for Controlling Access to Shelf Display Units will be described hereinafter. Although the invention is described in terms of specific illustrative embodiments, it is to be understood that the embodiments described herein are by way of example only and that the scope of the invention is not intended to be limited thereby.
[0030] In the following description, similar features in the drawings have been given similar reference numerals, and in order not to weigh down the figures, some elements are not referred to in some figures if they were already identified in another figure.
[0031] The use of the word “a” or “an” when used in conjunction with the term “comprising” in the claims and / or the specification may mean “one”, but it is also consistent with the meaning of “one or more”, “at least one”, and “one or more than one”. Similarly, the word “another” may mean at least a second or more.
[0032] As used in this specification and claim(s), the words “comprising” (and any form of comprising, such as “comprise’ and “comprises”), “having” (and any form of having, such as “have and “has”), “including” (and any form of including, such as “include and “includes”) or “containing” (and any form of containing, such as “contain” and “contains”), are inclusive or open-ended and do not exclude additional, unrecited elements.
[0033] As used herein the word “essentially” means “mostly, but not exclusively”.
[0034] It is also to be understood that the word “about” or “approximately” means an acceptable error for a particular value as determined by one of ordinary skill in the art, which depends in part on how the value is measured or determined. Insofar as it refers to percentages in the specification and claims, it means rounding up or down to the nearest whole number percentage. Insofar as it refers to other numbers in the specification and claims, it means plus or minus 10%.
[0035] For purposes of this specification and the appended claims, unless otherwise indicated, all numbers, material percentages or ratios, reaction conditions, and other numerical values are also to be understood as modified by the term “about” in all cases.
[0036] Accordingly, unless indicated to the contrary, the numerical parameters set forth in the following specification and appended claims are approximations that may vary depending on the desired properties sought to be obtained. Without attempting to limit the application of the doctrine of equivalents to the claims, at a minimum each numerical parameter should be interpreted in light of the reported number of significant figures and by applying normal rounding techniques.
[0037] Referring to FIG. 1, the system 100 is shown as an assembly comprising a support track 104 and modular transparent barriers 102. The barriers 102 are rectangular panels mounted vertically along the length of the support track 104. The barriers are hinged and open at a controlled angle (for example, about 45 degrees) in the locked mode to allow customers to take products one or two at a time. This design deters theft by preventing the removal of multiple items at once. The structure includes a locking mechanism that enables the barriers to fully open for merchants to restock products efficiently.
[0038] Referring to FIG. 2, an exploded view of the system 100 is presented, illustrating the primary components and their assembly. The system 100 comprises a support track 104, modular transparent barriers 102, a data track 200, mounting points 202, and optional components 204. The barriers are equipped with hinges and springs to ensure a controlled pivot and automatic return to the closed position. The support track 104 serves as the foundation for the system, with the transparent barriers 102 mounted along its length. The barriers are designed to pivot and are spaced for modular adaptability. The data track 200, appears as an auxiliary component designed for potential integration with electronic pricing or lighting systems. The mounting points 202 and accessory component 204 provide structural support and enable secure attachment of the system to a shelf or other surfaces.

FIG. 7 provides dimensional details and highlights mounting stability, while FIG. 8 focuses on the hinge mechanism's precision and attachment to the support track 104.
[0043] Referring to FIG. 7, the system 100 is illustrated in cross-section, showing the attachment of the transparent barriers 102 to the support track 104 via a hinge mechanism. The view emphasizes the vertical alignment of the components and the height measurements of the barriers 102 and support track 104, which together provide a secure and functional enclosure for retail products.
[0044] Referring to FIG. 8, a close-up of the hinge mechanism and mounting configuration is provided. The transparent barrier 102 is shown attached to the support track 104 using a precision hinge system. The detailed view includes the mounting hardware securing the support track 104 to its supporting structure, demonstrating the system's robust and modular design for easy installation and maintenance.
[0045] Referring to FIGS. 9-10, these figures demonstrate the alignment of the support track 104 and barriers 102 with a shelf 106. FIG. 9 shows the top view, emphasizing mounting point adaptability, and FIG. 10 shows the front elevation of the locked barriers 102, ensuring uniform alignment.
[0046] Referring to FIGS. 11-13, these figures provide detailed views of the system's integration with the shelf 106 and the mounting and hinge mechanisms. FIG. 11 (Section BK-BK) shows how the support track 104 is securely attached to the shelf 106 using mounting hardware. This view emphasizes the stability and alignment of the system, including how screws and securing nuts anchor the support track 104 to the shelf. The functionality of the locking mechanism is not depicted in this figure and is addressed in other views. FIG. 12 (Section BH-BH) illustrates the structural integration of the barriers 102 with the support track 104 and the shelf 106. This figure focuses on dimensional details and highlights the secure connection points, ensuring durability and alignment. The hinge mechanism and locking mechanism functionalities are not explicitly shown here. FIG. 13 (Detail BJ) provides a close-up view of the hinge mechanism, demonstrating how it attaches the transparent barriers 102 to the support track 104 and the shelf 106. The precision design of the hinges ensures smooth pivoting for controlled access. This figure does not depict the locking mechanism but highlights the robustness of the mounting hardware.
[0047] Referring to FIG. 14, an exploded view of the system 100 is presented, showing the detailed assembly of its components. This figure includes the support track 104, transparent barriers 102, optional features such as a lockable fence mechanism, and a data track 200 for displaying pricing information. The modular nature of the components enables customization, such as integrating pushers or omitting certain features.
[0048] Referring to FIG. 15, a perspective view of the fully assembled system 100 is shown. The barriers 102 are depicted in both their open and closed positions. In the locked mode, the barriers open to a controlled angle (for example, about 45 degrees) for limited customer access, while in the unlocked mode, the barriers can fully open to allow merchants to restock products efficiently. The springs ensure the barriers automatically return to the closed position when released.
[0049] Referring to FIGS. 16-19, these figures illustrate the individual mechanical components used in the assembly and operation of the system 100. FIG. 16 depicts a torsion spring, which provides the restoring force to return the barriers 102 to their closed position. FIG. 17 shows a mirrored version of the torsion spring, designed for use in alternate orientations. FIG. 18 illustrates a wing nut, used to secure the support track 104 to the shelf 106. FIG. 19 depicts a machine screw, which fastens the system components securely and ensures stability during operation. In another embodiment of the invention, the system may include the following optional features: pushers integrated into the shelving system for automated product merchandising; a lockable fence mechanism for additional security, which can be removed or customized for easier access; a data track integrated at the front of the metal structure for price display or compatibility with electronic pricing systems.
[0050] The present invention also provides a method for using the system 100 for controlling access to shelf display units involves the following sequence of actions:
[0051] The merchant uses a key or tool to disengage the locking mechanism located beneath the support track 104. Once unlocked, the barriers 102 can pivot fully open, allowing the merchant to have unobstructed access to the shelf 106 for restocking. With the barriers fully open, the products may be placed on the shelf. If the shelf includes optional pushers, the products can be arranged so that they are automatically guided to the front of the display for easier access.
[0052] After stocking the merchandise, the barriers 102 are returned to their closed position. The locking mechanism is then re-engaged, securing the barriers and ensuring they can only open to a controlled angle (for example, about 45 degrees) for customer interaction.
[0053] This allows the customer to pull a barrier 102 to pivot it open at a controlled angle (for example, about 45 degrees). This limited access allows the client to retrieve one item at a time while rendering more difficult if not impossible the removal of multiple items simultaneously by a sweeping action.
[0054] Once the client removes the desired product from the shelf, the torsion springs (FIGS. 16-17) in the hinge mechanism automatically return the barrier 102 to its closed position. This ensures that the system remains secure and organized without requiring manual intervention.
[0055] When restocking is required, the merchant repeats the process by unlocking the system 100, fully opening the barriers 102, replenishing the merchandise, and relocking the barriers 102 to secure the system 100.
[0056] The support track 104 is preferably made of metal but it may also be made of plastic or another sufficiently rigid material.
[0057] While illustrative and presently preferred embodiments of the invention have been described in detail hereinabove, it is to be understood that the inventive concepts may be otherwise variously embodied and employed and that the appended claims are intended to be construed to include such variations except insofar as limited by the prior art.
