[0001] COLLAPSIBLE DISPLAY AND DISPLAY SYSTEM WITH HINGED

[0002] AND SLIDABLE SIDE WALL SECTIONS

[0003] FIELD OF THE INVENTION

[0004] The field of the invention relates to collapsible displays and display systems for goods, specifically those which feature hinged and sliding connections between the shelves and the side walls. The invention further pertains to the use of telescopic extension means to adjust the height of the display, as well as the inclusion of automatic locking mechanisms and foldable back plates. The invention also extends to the design of the shelves, which are configured to rest upon each other in a folded state and house the side wall sections.

[0005] BACKGROUND

[0006] In the retail industry, displays are commonly used for presenting goods to customers. These displays, often composed of several shelves, are typically made of rigid materials and are fixed in their form. This poses several challenges. Firstly, transporting these displays can be difficult due to their bulkiness. Secondly, storage of these displays when not in use can also be problematic due to the large space they occupy. Furthermore, the height of these displays is often fixed, which limits their adaptability to different types of goods. Additionally, the assembly and disassembly of these displays can be time-consuming and require special tools. Therefore, there is a need for an improved display system that addresses these issues.

[0007] WO 2011 / 104 623 describes a telescopic display structure with multiple columns, each having at least two hollow parts, in which a portion of the second part can slide into the first part. The display structure comprises frames for shelves that are spaced by means of the columns.

[0008] Because the columns comprise hollow parts with a minimal length, the frames cannot slide one adjacent to the other which does not result in an optimal compactness for the transport of the display structure. Furthermore, the display structure does not comprise a variable number of frames and / or shelves because the minimal length of the hollow parts involves a non-negligible minimal spacing of the frames. Furthermore, building up of the display structure requires simultaneous pulling of a first frame, holding still a second frame, and pushing-in several attachment elements for telescopically extending the columns. This combination of operations is difficult or impossible to realize by one single person. Furthermore, objects can also easily fall through the side walls of the display structure. Indeed, the side walls do not comprise a means for supporting e.g. standing books.

[0009] CN 103 239 074 describes a portable and foldable display comprising a rectangular frame. The rectangular frame comprises four columns, a bottom plate comprising through-holes in the four corners, and attachments clamps. The columns are telescopic metal connection rods.

[0010] The display comprises shelves that can be spaced by means of the columns. Because the columns comprise telescopic parts with a minimal length, the shelves cannot slide one adjacent to the other which does not result in an optimal compactness for the transport of the display structure. Furthermore, the goods display also does not comprise a variable number of shelves that can be built-up. Furthermore, objects can also easily fall through the side planes of the goods display. Indeed, the side planes do not comprise a means for supporting e.g. standing books.

[0011] US 8 256 630 describes a frame structure with two side panels and a foldable frame coupled to the side panels for folding between a built-up and a folded configuration. The foldable frame comprises a connection piece that is supported between the side panels, a slideable hinging point coupled in a sliding way to the connection piece, and two foldable arms connecting the connection piece to the side panels. Each of the foldable arms has an upper end that is hingedly coupled to the slideable hinging point and a lower end that is hingedly coupled to a side panel.

[0012] SUMMARY OF THE INVENTION

[0013] The invention pertains to a collapsible display and display system for goods, characterized by a top and bottom shelf connected by oppositely positioned side walls. Each pair of side walls consists of a first and second side wall section, with the first section hingedly attached to the top shelf and slidably provided to the bottom shelf, and the second section hingedly attached to both the first section and the bottom shelf. The invention can incorporate a third side wall section, a bridge section, a common hinge axis, and a telescopic extension to adjust the height of the side wall sections. An automatic locking mechanism secures the side wall's position to the top shelf when perpendicular. The top and bottom shelves have flange sections that allow the side wall sections to rest in a cavity when the display is folded. The collapsible feature facilitates portability and storage, the telescopic extension enhances visibility, and the automatic locking mechanism provides stability. The invention offers a versatile, adaptable, and cost-efficient solution for displaying goods.

[0031] Reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment, but may. Furthermore, the particular features, structures or characteristics may be combined in any suitable manner, as would be apparent to a person skilled in the art from this disclosure, in one or more embodiments. Furthermore, while some embodiments described herein include some but not other features included in other embodiments, combinations of features of different embodiments are meant to be within the scope of the invention, and form different embodiments, as would be understood by those in the art. For example, in the following claims, any of the claimed embodiments can be used in any combination. The invention relates to a collapsible display and display system for exhibiting goods; The principles are the same for each device and as such, in the present text, the terms display (or display unit) and display system are often used mixedly, due to the shared principles of operation. As such, the teachings of each embodiment of one aspect should be considered to be disclosed for the other aspect as well.

[0032] In a first aspect, the present invention pertains to a collapsible display for exhibiting goods. The display, in a preferred embodiment, includes a top side and a bottom side. It comprises a bottom shelf situated at the bottom side and a top shelf positioned at the top side. These shelves are connected by a pair of oppositely positioned side walls. The arrangement of the top and bottom shelves coupled with the side walls provides a sturdy and stable structure for displaying goods.

[0033] The collapsible display is characterized by the unique design of its side walls. Each pair of side walls comprises at least a first and a second side wall section. The first side wall section is hingedly attached to the top shelf at its top end and slidably provided to the bottom shelf at its bottom end. This configuration allows the first side wall section to pivot about the hinged attachment with the top shelf and slide along the bottom shelf. The second side wall section is hingedly attached to the bottom shelf at its top end and to the first side wall section along a hinge axis that is parallel to the bottom and top shelf. This design facilitates a folding motion between the first and second side wall sections, enabling the display to be collapsed into a compact form.

[0034] By having the side wall sections being hingedly attached to each other, while unfolding in a different manner, the side wall as a whole, when erected, will have a much greater stability and cannot be folded or bent without application of extreme force. Even more so since the way the first and second side wall sections unfold in a directly opposite way, with the hinged attachment to the shelves at opposite ends, all the while sharing the common hinge axis.

[0035] The slidable provision of the side wall sections does not necessarily constitute a direct connection to the shelves, and can simply mean that the ends of the side wall sections slide along or close to the shelves when unfolding and collapsing. They can be slidably attached via a track, although this is preferably not the case to simplify production and operation.

[0036] The collapsible display introduces a new level of portability and flexible structuring of a display system. It can be easily collapsed and transported, making it particularly beneficial for users who need to set up and use the display system in different locations. The collapsible design also allows for quick and convenient assembly wherever it is needed.

[0037] It is however envisioned within the scope of the invention that the setup of the display is reversed, with the top shelf functioning as the bottom shelf and vice versa. The principles of operation remain the same, and all further embodiments are applicable to such a variation as well.

[0038] In a potential embodiment, the first and second side wall sections are of equal length, providing a balanced and symmetrical structure when the display is erected. In other embodiments, the first side wall section is shorter than the second side wall section. However, in preferred embodiments, the first side wall section is longer than the second side wall section, preferably about twice as long in an unextended state (without telescopic extensions for instance). Setting the lengths at a (maxima) ratio of 2 to 1 allows the system to collapse in a most efficient way (minimal total length in collapsed state), such that side wall sections of opposite side walls do not overlap when the width of the display is chosen to be at least 2 times the total length of the (first) side wall section in collapsed state.

[0039] The hinge attachment and slidable provision of the side wall sections to the shelves are designed to provide a secure and robust connection while allowing for easy disassembly and reassembly of the display. In a preferred embodiment, the hinges are made of durable materials such as metal or hard plastic, and the slidable provision are designed to smoothly glide along the bottom shelf without causing damage or wear.

[0040] In conclusion, the collapsible display of the present invention provides a practical and innovative solution for displaying goods. Its unique design enables it to be easily transported and set up in various locations, offering a high level of flexibility and convenience for the user.

[0041] In a preferred embodiment of the invention, each pair of side walls further comprises a third side wall section. This third side wall section is integral to the enhanced versatility and adaptability of the display system. The top end of the third side wall section is hingedly attached to the top shelf, allowing for a degree of flexibility and movement, while the bottom end of the third side wall section is slidably provided to the bottom shelf. This combination of hinged connections and sliding provisions facilitates a smooth transition from a collapsed to an extended state, and vice versa. More exactly, by having three separate side wall sections, the overall structural integrity and stability is improved.

[0042] The second side wall section of each pair is hingedly attached to the third side wall section along a hinge axis. This hinge axis serves as a pivot point, around which the side wall sections can rotate, thereby enabling the display system to collapse into a flat state. The positioning of the second side wall section between the first and the third side wall sections in each pair further contributes to the compactness of the display when collapsed, and to its stability when extended. More specifically however, it greatly increases the structural stability, by the first and third side wall sections flanking the second. The two groups (first and third vs. second) collapse 'oppositely', which makes their lateral support of each other more effective.

[0043] As mentioned previously, the third wall section is preferably of the same length, and optimally

[0044] In a more preferred embodiment, the hinge axis is positioned at a midpoint of the (unextended) third side wall section (and most preferably thus also of the first), more preferably at a point equidistant from the top and bottom ends of the third side wall section. This positioning ensures a balanced distribution of the weight of the display system across the side wall sections, thereby enhancing the stability of the display system in both its collapsed and extended states, and in the meanwhile, reducing total length in collapsed state to avoid overlapping side wall sections of opposite side walls.

[0045] In a preferred embodiment, the side wall sections are of identical dimensions. This ensures that the display system, when collapsed, forms a compact, flat package, with the side wall sections and the shelves stacked neatly on top of each other. The identical dimensions of the side wall sections also facilitate the process of collapsing and extending the display system, as the side wall sections can slide and rotate smoothly along the hinge axis and the sliding provisions.

[0046] In a preferred embodiment, the first and third side wall sections are of identical dimensions.

[0047] Preferably, the total widths of the side walls is lower than the total depth (dimension along the edge at which the side walls are positioned in erected form) of the top and bottom shelf, thus providing the shelves with a 'balcony' that extends from the display, which provides for interesting options in terms of product display, advertisement, etc. Preferably, the total height of the side walls (and thus of the side wall sections) is lower than the width of the top and bottom shelf (distance between the two side walls when the display is erected). This allows the side walls to be fully foldable against the bottom shelf, without overlapping each other (and thus adding to the height of the folded display).

[0048] The enhanced versatility and adaptability of this preferred embodiment of the collapsible display (system) cater to varying display settings and requirements. The collapsible display system can be quickly and easily set up in a variety of locations, and can be adapted to display a wide range of items, from small, lightweight objects to larger, heavier items. The collapsible display system is thus not only practical and convenient, but also highly versatile and adaptable.

[0049] In a preferred embodiment of the invention, the collapsible display is characterized by a unique configuration of side wall sections and bridge sections. The side wall sections are arranged in pairs, with each pair comprising a first and a third side wall section. The first and third side wall sections are connected via a bridge section, which is hingedly attached to the top end of an intermediate second side wall section. This arrangement facilitates the collapsible feature of the display, enabling it to transition into a flat state when not in use. This feature greatly enhances the portability of the display and makes its storage more convenient, particularly in environments where space is a premium. Furthermore, it allows the top shelf to be supported over its entire depth, instead of only at the first and third side wall sections. Most importantly however, it fixedly connected the first and third side wall sections, such that they move in unison, greatly simplifying the collapsing and unfolding of the side walls. In embodiments where the second side wall sections is positioned in between, it provides for a concerted actuation on the second side wall section from both sides.

[0050] The bridge section in this embodiment serves as a pivotal connection between the first and third side wall sections. It is hingedly attached to the top end of the second side wall section, allowing the first and third side wall sections to fold over the second side wall section when the display is collapsed. This configuration optimizes the use of space and contributes to the overall compactness of the display when in its collapsed state. The hinged connection of the bridge section to the second side wall section also ensures a smooth and controlled transition between the expanded and collapsed states of the display, preventing any abrupt or uncontrolled movement that could potentially damage the display or its contents. In a more preferred embodiment, the bridge section is dimensioned such that its length is equal to or greater than the combined width of the first, second and third side wall sections. This ensures that the first and third side wall sections connects to each side wall section and a hinged connection is present over the entire depth of the top shelf. Alternatively, the bridge section may be dimensioned such that its length is less than the combined lengths of the first and third side wall sections, allowing for a more compact collapsed state, reduction of materials necessary and reduced rigidity of the hinging action.

[0051] In a preferred embodiment, the bridge section and the side wall sections are constructed from a rigid and durable material, capable of withstanding repeated folding and unfolding operations without losing their structural integrity. The choice of material may also contribute to the overall weight of the display, with lighter materials being preferred for applications where portability is a key concern.

[0052] In conclusion, the present invention provides a collapsible display with a unique arrangement of side wall sections and bridge sections, which together enable the display to transition smoothly and efficiently between an expanded state and a flat, collapsed state. This feature enhances the portability of the display and facilitates its storage, contributing to its practicality and versatility in a wide range of applications. In a preferred embodiment of the invention, the collapsible display is characterized by a unique configuration of side wall sections. For every pair, these side wall sections of the separate pairs of side walls are hingedly connected to each other along a common hinge axis. This axis is parallel to the bottom and top shelf, ensuring a consistent and reliable folding mechanism.

[0053] The hinged connection of the side wall sections provides the collapsible display with its key attribute of collapsibility. This allows the display unit to be folded when not in use, thereby facilitating efficient use of space. This is particularly advantageous in environments where space is at a premium, such as retail stores, exhibition halls, or even residential settings, and importantly during transport. The ability to collapse the display to a flat state when not in use maximizes the available space and enhances the overall versatility of the unit.

[0054] In a further embodiment, the hinge axis may be positioned at varying distances from the top and bottom shelves. This allows for a range of folding configurations, providing further flexibility in the use of the display unit. Optimally it is positioned at half the height of the unextended side wall sections (without telescopic extension), as this optimizes length and foldability. The distance between the hinge axis and the bottom end of the side wall sections (connected to the bottom shelf) could range from a few centimeters to several decimeters, depending on the specific requirements of the use case. Preferably, the distance is between 4 and 20 centimeters and more preferably between 6 and 12 centimeters. Most preferably, it is between 8 and 10 cm. However, in other variants, the distance may be between 10 and 40 cm, for instance between 10 and 30 cm, between 10 and 20 cm, between 15 and 30 cm, between 15 and 25 cm, between 15 and 20 cm, or other dimensions.

[0055] The side wall sections themselves can be of various dimensions and shapes, again depending on the specific use case. In a preferred embodiment, they are rectangular in shape, but other shapes such as square, triangular or even circular could also be used. The height dimensions of the side wall sections could range from a few centimeters to several decimeters, with the specific dimensions chosen based on the size and shape of the items to be displayed. More preferably, the height dimensions are between 10 centimeters and 2 centimeters, and most preferably between 50 centimeters and 1 meter.

[0056] In yet another embodiment, the material of the side wall sections is chosen based on the weight and durability requirements. Lightweight materials such as plastic or aluminum can be used for easy transport and setup, while more durable materials such as steel or wood can be used for more permanent installations. The choice of material also affects the overall look and feel of the display unit, contributing to its aesthetic appeal.

[0057] In conclusion, the collapsible display according to the present invention provides a versatile and space-efficient solution for displaying items. Its unique configuration of hingedly connected side wall sections allows for a range of folding configurations, maximizing the use of available space and enhancing the overall versatility of the unit.

[0058] In a preferred embodiment of the invention, the collapsible display, as described in the preceding embodiments 1 to 4, includes at least one of the side wall sections for each pair, preferably the first side wall section, and more preferably also the third side wall section, which comprises a telescopic extension means. This telescopic extension means is configured for extending the height of said at least one of the side wall sections.

[0059] In this preferred embodiment, the telescopic extension means is designed in such a manner that it can effectively extend the height of the collapsible display. This extension of the height of the display is not merely a physical modification, but it brings about a significant enhancement in the visibility of the display. The increased height of the display makes it more visually impactful and noticeable to passers-by and viewers. This is particularly advantageous in scenarios where the collapsible display is used in crowded or large spaces, where increased visibility can significantly improve the effectiveness of the display.

[0060] The telescopic extension means is designed to be easily operable, facilitating the extension and retraction of the height of the collapsible display as required. This ease of operation does not compromise the stability of the display, ensuring that the display remains sturdy and secure even when the height is extended. The telescopic extension means can be constructed from a variety of materials, including but not limited to metal, plastic, or composite materials, depending on the specific requirements of the display and the environment in which it is to be used.

[0061] In a more preferred embodiment, both the first and the third side wall sections comprise a telescopic extension means. This allows for a greater degree of flexibility and adaptability in adjusting the height of the collapsible display. The option to extend the height of both side wall sections simultaneously provides an opportunity to create a larger display surface, thereby further enhancing the visual impact of the display. Alternatively, the option to extend the height of only one side wall section at a time allows for the creation of asymmetrical display configurations, which can be used to create unique and eye-catching display setups.

[0062] In the most preferred embodiment, the telescopic extension means is configured to extend the height of the side wall sections by a range of dimensions. The extension could be between 10 and 50 cm, more preferably between 20 and 40 cm, and most preferably between 30 and 35 cm. This range of dimensions provides a significant degree of versatility, allowing the collapsible display to be adapted to a variety of different display scenarios and requirements. The ability to adjust the height of the display within this range of dimensions ensures that the collapsible display can be tailored to achieve the maximum visual impact and visibility in any given situation.

[0063] The length / height of the telescopic extension means is preferably equal to the height of the first and third side wall sections, as it housed therein when not extended. However, variations are envisioned in which the telescopic extension means comprises multiple extension steps, with a second telescopic extension means being housed in the telescopic extension means which can extend therefrom, and potentially even a third, fourth, etc., in order to obtain a desired total height.

[0064] Preferably, the telescopic extension means is configured to remain at least partly within the side wall sections, for instance, by comprising a base that is broader than the through-hole in the side wall sections through which it can be extended. However, other options exist thereto.

[0065] In a preferred embodiment of the invention, the collapsible display is defined by a unique arrangement of its components, particularly the first side wall section, and the third side wall section, which are hingedly attached to the top shelf via the telescopic extension means. This design feature provides the collapsible display with enhanced portability, as it allows for easy collapsibility. The telescopic extension means is pivotal in achieving this as it provides the flexibility required for the side wall sections to fold in and out with ease.

[0066] The telescopic extension means is designed in such a way that it provides a secure connection between the side wall sections and the top shelf, while also allowing for the necessary movements during the collapsing and expanding of the display. In this preferred embodiment, the telescopic extension means is robust enough to withstand repeated use, ensuring the longevity of the collapsible display. It is also designed to be user-friendly, requiring minimal effort to operate, thus making the collapsible display suitable for users of all ages and physical abilities.

[0067] Moreover, the telescopic extension means may be designed in various dimensions to suit different needs. For instance, in a more preferred embodiment, the telescopic extension means may have a length ranging between 10 and 50 cm, more preferably between 20 and 40 cm, and most preferably between 30 and 35 cm. This range of lengths allows for the collapsible display to be adapted to different sizes, enhancing its versatility and usability. The dimensions of the telescopic extension means can be adjusted according to the specific requirements of the user or the environment in which the collapsible display is to be used.

[0068] Furthermore, the first side wall section, and the third side wall section, are hingedly attached to the top shelf in such a way that they provide stability to the collapsible display when it is in its expanded state. The hinges are designed to be strong and durable, capable of supporting the weight of the display and any items placed on it. In a potential embodiment, the hinges may be made from a material such as steel or aluminium, which provides the necessary strength and durability, while also being lightweight to maintain the overall portability of the collapsible display. Alternatively, these can be made from plastics, which allows single-piece manufacturing, provides sufficient strength and durability, can be easily produced and is very lightweight.

[0069] In conclusion, the collapsible display according to this preferred embodiment provides a practical and efficient solution for displaying items in a variety of settings. The unique design of the side wall sections, hingedly attached to the top shelf via the telescopic extension means, preferably via a bridge that connects the two telescopic extension means directly to each other at the top end thereof, not only enhances the portability of the display system by facilitating easy collapsibility, but also ensures its stability and durability, making it a reliable and versatile tool for display purposes.

[0070] In a preferred embodiment of the invention, the collapsible display is designed as per the specifications of the preceding embodiments, 5 and 6. This design encompasses a telescopic extension means, which is specifically dimensioned to be retained within the first side wall section. Optionally, it can also be retained within the third side wall section. The telescopic extension means is further characterized by a blocking protrusion, which is inherently biased to protrude from the telescopic extension means, and is retractable within the telescopic extension means. This retraction is facilitated preferably via a manipulable retraction mechanism that is connected to the blocking protrusion.

[0071] The first side wall section, and optionally the third side wall section, are designed with at least one opening. However, in a more preferred embodiment, multiple openings are present at different positions along the height of the side wall section. The blocking protrusion is carefully dimensioned to extend into, and preferably through said opening. This structural design enables the blocking protrusion to lock the telescopic extension means and the first, and optionally the third, side wall section in position when the blocking protrusion is extended in or through said opening.

[0072] The above-mentioned design and arrangement of the collapsible display system provide an effective and reliable system for achieving stability in a variety of positions and uses. This innovation benefits the user with enhanced customization and stability during its use. The design of the blocking protrusion and its interaction with the side wall sections ensures that the display remains stable and secure in all positions. This embodiment, therefore, not only provides the user with a versatile and adaptable display system but also ensures that the system is reliable and secure. In a more preferred embodiment, the openings in the side wall sections can be spaced at regular intervals, which can range from 5 to 30 mm, more preferably between 10 and 25 mm and most preferably between 20 and 25 mm. This arrangement allows for a greater degree of customization and flexibility in the positioning of the display system. The size of the blocking protrusion can also be varied according to the size and dimensions of the openings in the side wall sections. In a preferred embodiment, the size of the blocking protrusion is between 1 and 5 mm, more preferably between 2 and 4 mm, and most preferably around 3 mm. This size ensures that the blocking protrusion fits securely into the openings in the side wall sections, thereby providing a secure and stable display system.

[0073] The design of the telescopic extension means and the blocking protrusion, along with the arrangement of the side wall sections and the openings therein, ensure that the collapsible display system is not only versatile and customizable, but also secure and reliable. The user can easily adjust the position and orientation of the display system according to their needs, while also being assured of the stability and security of the system.

[0074] In a preferred embodiment of the invention, the collapsible display further includes a back plate. This back plate is hingedly attached to the top shelf at a rear edge. The hinge attachment allows the back plate to fold against the bottom of the top shelf. The addition of the back plate to the display structure enhances the overall sturdiness of the display. By being hingedly attached to the top shelf, the back plate provides an additional layer of support to the top shelf, thereby reinforcing the display structure and ensuring that it can withstand various loads.

[0075] Furthermore, the back plate serves a protective role for the design elements of the display. By folding against the bottom of the top shelf, the back plate shields the design elements from potential damage, enhancing the durability of the display. This is particularly advantageous in scenarios where the display is exposed to harsh conditions or heavy use. Therefore, the back plate not only contributes to the structural integrity of the display but also helps maintain the aesthetic appeal of the design elements over prolonged periods of use.

[0076] Moreover, the foldable nature of the back plate adds to the collapsibility of the display system. When not in use, the back plate can be folded against the bottom of the top shelf, reducing the overall size of the display system. This collapsible feature significantly improves the storage and transport capabilities of the display system. It allows the display system to be compactly stored and easily transported, making it highly convenient for users. It also reduces the risk of damage during transport, as the folded state provides an additional layer of protection to the display elements. In a more preferred embodiment, the back plate and the top shelf are hingedly attached using a hinge mechanism that allows for a smooth and easy folding process. The hinge mechanism can be designed to provide a certain degree of resistance, ensuring that the back plate stays securely in place when unfolded. In the most preferred embodiment, the hinge mechanism is designed to allow the back plate to fold completely against the bottom of the top shelf, ensuring that the display system can be collapsed to its smallest possible size for optimal storage and transport efficiency.

[0077] In a preferred embodiment of the invention, the collapsible display is equipped with side walls, each of which incorporates a locking mechanism. This mechanism is engineered to automatically lock the position of the side wall to the top shelf when the side wall attains a perpendicular position relative to the top shelf. The automatic locking mechanism is a key feature, as it imparts a high degree of stability to the display when it is fully set up. This ensures that the display remains firmly in place, thereby reducing the risk of accidental collapses or shifts that could disrupt the presentation of the displayed items or information.

[0078] Furthermore, the locking mechanism includes a manipulable unlocking means. This unlocking means is designed to be user-friendly, allowing users to easily unlock the locked position of the side wall. This feature facilitates the manipulation of the display, making it simple for users to adjust the display to their specific needs or preferences. Moreover, the unlocking means also enables users to easily collapse the display when it is no longer needed, thereby enhancing the convenience and practicality of the display.

[0079] In a more preferred embodiment, the locking mechanism is configured to automatically engage when the side wall is at an angle of 90 degrees to the top shelf. This specific angle ensures that the display is optimally stable when set up. However, in other embodiments, the locking mechanism may be designed to engage at angles slightly less than or greater than 90 degrees, depending on the specific requirements or constraints of the display system. For instance, in some embodiments, the locking mechanism may engage at an angle of 85 to 95 degrees to the top shelf. In other embodiments, the locking mechanism may engage at an angle of 80 to 100 degrees to the top shelf.

[0080] In the most preferred embodiment, the unlocking means is a lever or button that can be easily manipulated by hand. This design makes it straightforward for users to unlock the side wall, regardless of their level of technical skill or experience. However, in other embodiments, the unlocking means may take other forms, such as a switch, a slide, or a dial. The specific design and operation of the unlocking means may be tailored to the particular needs and preferences of the users, as well as the specific characteristics and constraints of the display system.

[0081] In a preferred embodiment of the invention, the collapsible display is characterized by a top and bottom shelf, each comprising a substantially flat top side and a bottom side. The top shelf is further characterized by one or more upper flange sections along the edge of the top side that protrude upwards, while the bottom shelf includes one or more lower flange sections along the edge of the bottom side that protrude downwards. These flange sections are an integral part of the collapsible display design, contributing to its functionality and efficiency.

[0082] When the display is in a folded state, the lower flange sections of the top shelf and the upper flange sections of the bottom shelf are configured to rest upon each other. This arrangement not only ensures stability and balance of the folded display, but also provides a compact, streamlined configuration that is easy to handle and store. This is particularly advantageous in situations where storage space is at a premium, as the folded display takes up minimal volume.

[0083] Another distinguishing feature of this embodiment is the positioning of the side wall sections. In the folded state, the side wall sections are conveniently positioned in a cavity. This cavity is created by the lower flange sections of the top shelf, the upper flange sections of the bottom shelf, and the top and bottom shelf themselves. By utilizing this cavity for the side wall sections, the overall volume of the folded display is further reduced, resulting in even greater space saving.

[0084] In a more preferred embodiment, the dimensions of the cavity are such that they perfectly accommodate the side wall sections, allowing for a snug fit that prevents any unnecessary movement or shifting of the side wall sections when the display is folded. This ensures that the folded display maintains a neat, tidy appearance, and also protects the side wall sections from any potential damage during storage or transportation. In a most preferred embodiment, the top and bottom shelves and the side wall sections are made from a durable, lightweight material that can withstand the rigors of frequent folding and unfolding. The use of such a material also contributes to the compactness and portability of the folded display, making it an ideal solution for a wide range of display needs.

[0085] To conclude, the design and configuration of the collapsible display according to this embodiment offer significant advantages in terms of storage efficiency, ease of handling, and durability. The unique arrangement of the top and bottom shelves and the side wall sections, coupled with the use of flange sections and a cavity for storing the side wall sections when folded, result in a collapsible display that is not only practical and versatile, but also aesthetically pleasing.

[0086] In a second aspect, the present invention relates to a collapsible display system for displaying goods. The display system generally functions by the same principles as the collapsible display, and the embodiments of the display are typically applicable to the display system. The display system can be constructed by stacking separate displays on top of each other and affixing them, but preferably, it is constructed by integrating the displays in a single system, by using the top shelf of a lower display as the bottom shelf of the display above it, and so on, thus reducing the need to have two separate shelves between each 'level'.

[0087] In a preferred embodiment, the display system comprises a top side and a bottom side, and includes three or more vertically stacked shelves. This configuration provides the advantage of maximizing the display area without occupying a large footprint, thus making it suitable for use in space-constrained environments.

[0088] In a further embodiment, the display system includes a pair of oppositely positioned side walls connecting every two subsequently stacked shelves. This arrangement provides stability to the display system, ensuring that the goods displayed on the shelves are secure and unlikely to fall.

[0089] In a preferred embodiment, each of the pairs of side walls comprises at least a first and a second side wall section. The first side wall section is hingedly attached at its top end to a first shelf of the two subsequently stacked shelves, preferably the top shelf of said two subsequently stacked shelves. This hinged attachment allows the first side wall section to pivot relative to the first shelf, enabling the display system to be collapsed or expanded as required. The bottom end of the first side wall is slidably provided to a second shelf of said two subsequently stacked shelves, preferably to the bottom shelf of said two subsequently stacked shelves. This sliding provision allows the first side wall section to move relative to the second shelf, further facilitating the col la psibi lity of the display system.

[0090] In a further embodiment, a top end of the second side wall section is hingedly attached to the second shelf. This arrangement allows the second side wall section to pivot relative to the second shelf, which aids in the transformation of the display system between its expanded and collapsed states. The second side wall section is hingedly attached to the first side wall section along a hinge axis parallel to the second and first shelf. This configuration allows the second side wall section to pivot relative to the first side wall section, enabling the display system to fold in a manner that minimizes its overall size when collapsed.

[0091] The collapsible design of the display system facilitates easy transportation and storage, leading to cost and space efficiency. This is particularly advantageous in situations where the display system needs to be frequently moved or stored, such as in retail environments or at trade shows. The collapsible design also reduces the risk of damage during transportation, as the display system can be collapsed to a compact size that is less likely to be impacted by other objects.

[0092] In a preferred embodiment, the display system is constructed from durable materials to withstand the rigors of frequent use. These materials may include, but are not limited to, metals, plastics, or composite materials. The choice of material can vary depending on the specific requirements of the application, such as the weight of the goods to be displayed or the environmental conditions in which the display system will be used. Most preferably, the materials used are plastics or composite materials, as these provide for a lighter system, which is easier to handle and manipulate.

[0093] In a preferred embodiment of the invention, the collapsible display system is further defined by incorporating a third side wall section in each pair of side walls. The third side wall section is hingedly attached at its top end to the first shelf and at its bottom end is slidably provided to the second shelf. This configuration allows the side walls to fold in on themselves, providing a more compact and streamlined design when the display system is collapsed.

[0094] The second side wall section is hingedly attached to the third side wall section along a hinge axis. This hinge axis allows for the side wall sections to pivot around a central point, facilitating the folding and unfolding of the display system. The arrangement of the second side wall section between the first and the third side wall section further enhances the stability of the display system when it is in its erected state. It also serves to protect the hinge axis and other internal components of the display system when it is in its collapsed state.

[0095] The collapsible design of the display system considerably enhances its transportability and ease of storage when not in use. The display system can be quickly and easily collapsed, reducing its volume and making it more convenient to transport or store. This is particularly advantageous in environments where space is at a premium, such as in retail settings or at trade shows. The collapsible design also reduces the risk of damage to the display system during transport, as it can be securely packaged in its collapsed state.

[0096] In a preferred embodiment, the third side wall section has a length between 50 and 100 cm, more preferably between 60 and 90 cm and most preferably between 70 and 80 cm. This range of lengths allows for a display system that is large enough to effectively display products or information, but not so large as to be unwieldy or difficult to transport or store. The dimensions of the third side wall section can be adjusted to suit the specific requirements of the user, providing further flexibility and adaptability. In another embodiment, the hinge axis is positioned at a height between 10 and 20 cm from the base of the display system, more preferably between 12 and 18 cm and most preferably between 14 and 16 cm. This positioning of the hinge axis ensures that the display system is stable and secure when in its erected state, while also allowing for easy and efficient folding and unfolding.

[0097] In a preferred embodiment, the collapsible display system as described above includes a unique arrangement of side wall sections and a bridge section. This configuration allows for enhanced portability and storage capacity, a feature that is highly desired by users who require display systems that can be easily transported and stored.

[0098] The collapsible display system comprises, for each pair, first and third side wall sections that are interconnected by a bridge section. This bridge section is hingedly attached to the top end of the second side wall section. This hinged attachment allows the bridge section to pivot around the top end of the second side wall section, thereby enabling the collapsible display system to be folded into a flat state for easy storage and transportation. The hinged attachment of the bridge section to the second side wall section is of particular importance. This pivotal connection allows for the efficient collapse of the display system, thereby greatly improving its portability. In a more preferred embodiment, the hinge is designed to allow for a full 180-degree rotation, which further enhances the coIla psibi lity of the display system.

[0099] Furthermore, the bridge section provides additional structural support to the display system. When the display system is in its expanded state, the bridge section acts as a stabilizing element that helps to maintain the structural integrity of the display system. This ensures that the display system remains sturdy and stable, even when loaded with items for display.

[0100] In a most preferred embodiment, the bridge section is made from a durable material, such as metal or hard plastic, that is capable of withstanding the rigors of frequent use. The use of such materials also contributes to the overall durability and longevity of the collapsible display system.

[0101] Moreover, the bridge section may be designed in various shapes and sizes to accommodate different display needs. In a more preferred embodiment, the bridge section is rectangular in shape, which provides optimal support and stability. However, in other embodiments, the bridge section may be circular, triangular, or any other shape that meets the user's display requirements.

[0102] Overall, the collapsible display system, with its unique arrangement of side wall sections and a bridge section, offers a practical and efficient solution for users who require portable and easy-to-store display systems. Its innovative design not only enhances its portability and storage capacity, but also improves its structural stability, making it an optimal choice for a wide range of display applications.

[0103] In a preferred embodiment of the collapsible display system, at least one of the side wall sections for each pair, more preferably the first side wall section, and most preferably also the third side wall section, comprises a telescopic extension means. This telescopic extension means is specifically configured for extending the height of the said at least one of the side wall sections. The use of such telescopic extension means provides a significant advantage in terms of adaptability and space utilization. This telescopic extension means allows for adjusting the height of the display shelves, providing a versatile solution for space utilization. This means that the height of the display shelves can be adjusted according to the specific requirements of the displayed items, thereby maximizing the use of the available space. The use of a telescopic extension means also provides the advantage of being able to accommodate items of different sizes, thereby increasing the versatility of the display system.

[0104] In a more preferred embodiment, the telescopic extension means can be extended to a maximum height of 200 cm, more preferably between 150 cm and 200 cm, and most preferably between 175 cm and 200 cm. This range of height adjustment provides a suitable solution for displaying items of various sizes, while also ensuring that the display system remains stable and secure.

[0105] In an even more preferred embodiment, the telescopic extension means is designed to be easily manipulated, allowing for quick and effortless adjustment of the height of the display shelves. This could be achieved, for example, through the use of a simple locking mechanism, which can be engaged and disengaged to adjust the height of the display shelves.

[0106] In a further preferred embodiment, the telescopic extension means is made from a durable and robust material, such as metal or hard plastic, to ensure that it can withstand the weight of the displayed items. The use of such materials also ensures that the telescopic extension means is resistant to wear and tear, thereby increasing the longevity of the display system.

[0107] In conclusion, the use of a telescopic extension means in a collapsible display system provides a versatile and adaptable solution for space utilization. It allows for the height of the display shelves to be easily adjusted according to the specific requirements of the displayed items, while also ensuring that the display system remains stable and secure. The use of durable and robust materials further enhances the longevity of the display system.

[0108] In a preferred embodiment of the present invention, the collapsible display system includes a telescopic extension means that is dimensionally designed to be retained within the first side wall section, and optionally within the third side wall section. The telescopic extension means is advantageously comprised of a blocking protrusion. This blocking protrusion is biased to protrude from the telescopic extension means and is retractable within the telescopic extension means. The retraction of the blocking protrusion is preferably facilitated via a manipulable retraction mechanism that is connected to the blocking protrusion. This allows the user to easily adjust the height and viewing angles of the display system, offering a beneficial effect of userpreferred modifications and on-the-fly adjustments.

[0109] In a more preferred embodiment of the invention, the first, and optionally the third, side wall section of the collapsible display system includes at least one opening. This opening may be located at different positions along the height of the side wall section, providing multiple options for the height adjustment of the display system. The blocking protrusion is dimensionally designed to extend into and preferably through the said opening, providing a secure lock for the telescopic extension means and the first and optionally third side wall section when the blocking protrusion is extended in or through the opening. This embodiment offers the advantage of stability and robustness, ensuring the display system remains in the desired position once adjusted.

[0110] The blocking protrusion preferably protrudes laterally from the telescopic extension means, such that it can be extended through a lateral opening in the side walls sections, perpendicularly to the height dimension of the side wall section, thus blocking the telescopic extension means with respect thereto when the protrusion extends through the opening.

[0111] In a preferred embodiment, the blocking protrusion can be retracted or moved out its biased extended position, such that it no longer extends through the opening and doesn't block the telescopic extension means. The manipulable retraction means is preferably positioned at a different point, for instance at a handle position on the side walls.

[0112] In the most preferred embodiment, the blocking protrusion is dimensionally designed to have a length between 2mm and 10mm, more preferably between 4mm and 8mm, and most preferably around 6mm. This range of length provides a balance between the strength of the blocking protrusion and the ease of manipulation for the user. The diameter of the blocking protrusion is preferably between 0.5mm and 2mm, more preferably between 0.75mm and 1.5mm, and most preferably around 1mm. This range of diameter offers a balance between the robustness of the blocking protrusion and the size of the opening in the side wall section.

[0113] The manipulable retraction mechanism connected to the blocking protrusion is preferably a button, a lever, or a knob, which can be easily manipulated by the user. The retraction mechanism is preferably positioned at a convenient location on the display system, allowing the user to easily access it for quick and easy adjustments of the height and viewing angles of the display system. This embodiment enhances the user-friendliness and practicality of the display system, making it more suitable for various use environments and display options.

[0114] In a preferred embodiment, the shelves (and thus the display / display system) have a width (distance between the two side walls when erected) between 20 cm and 60 cm, preferably between 25 cm and 52 cm, more preferably between 30 cm and 44 cm, most preferably between 33 cm and 39 cm, for instance 34 cm, 34.5 cm, 35 cm, 35.5 cm, 36 cm, 36.5 cm, 37 cm, etc.

[0115] In a preferred embodiment, the shelves have a depth (distance between front and back) between 20 cm and 60 cm, preferably between 25 cm and 55 cm, more preferably between 30 cm and 50 cm, even more preferably between 35 cm and 45 cm, and most preferably between 37 cm and 43 cm, for instance 38 cm, 38.5 cm,

[0116] 39.5 cm, 40 cm, 40.5 cm, 41 cm, 41.5 cm, 42 cm, etc.

[0117] In a preferred embodiment, the side walls, when erected but not extended (i.e. distance between the shelves when erected), have a height between 25 cm and 55 cm, more preferably between 30 cm and 50 cm, even more preferably between 35 cm and 45 cm, and most preferably between 37 cm and 43 cm, for instance 38 cm,

[0118] 38.5 cm, 39.5 cm, 40 cm, 40.5 cm, 41 cm, 41.5 cm, 42 cm, etc.

[0119] In a preferred embodiment, the display system is provided with a base frame at the bottom, on which wheels can be attached. The shelves are mounted onto the base frame in a stacked configuration. The base frame is further provided with one or more weight sensors capable of weighing the structure that is mounted onto base frame. These weight sensor are preferably provided with a wireless communication means capable of wireless communication of weight data from the weight sensor, such as via Wi-Fi, Bluetooth (BLE), and other such means, optionally making use of a gateway in the vicinity that performs the further forwarding of the weight sensor data.

[0120] Typically, the shelves are rectangular, in which case the base frame is preferably also rectangular, or in the form of an actual frame, as seen in the Figures. In these embodiments, the weight sensors are preferably mounted at the outer edges and most preferably on each of the corners of the base frame. In some embodiments a base frame can be provided on top of each top shelf (optionally excepting the top shelf of the topmost layer) of a multi-story display system, in order to weigh the layers above each shelf. This way, it can determine the weight of each separate layer by subtraction of the weights detected by the layer above it.

[0121] In a preferred embodiment, the telescopic extension means of a side are connected to each other via a bridge which comprises a handle, preferably where the retractable manipulation mechanism is also provided. This connection improves stability, and allows for a better connection to the top shelf. Additionally, by providing a handle here, it allows the system to be carried or moved more easily.

[0122] The shelves preferably have a thickness of about 2 cm to 8 cm, more preferably between 3 cm and 7 cm, even more preferably between 4 cm and 6 cm.

[0123] In a preferred embodiment, the side walls can be extended to at least one, two, three or more height positions via the telescopic extension means. The extension preferably provides for a maximal additional height of 5 to 30 cm, preferably between 10 cm and 20 cm, more preferably between 11 cm and 15 cm.

[0124] In embodiments with multiple height positions, these typically provide for a height increase (between subsequent height positions) between 2 cm and 15 cm, preferably between 4 cm and 10 cm, more preferably between 5 cm and 8 cm.

[0125] The display system preferably comprises at least two or more 'levels', meaning it comprises at least three or more shelves. However, in preferred embodiments, it comprises at least 4, 5, 6, 7, 8 or more shelves, where care must be taken to maintain a suitable maximal height (for instance, making it still manageable for a person to reduce to collapsed form without ladders, steps, etc.). A total height in fully extended form can thus be set at a maximum of 2.25 m, or 2.10 m, 2.0 m, 1.9 m, 1.8 m, 1.75 m or less, such as 1.7 m, 1.65 m, etc.

[0126] In a collapsed form, the display system preferably has a maximal height of at most 0.60 m, preferably of at most 0.55 m, more preferably of at most 0.50 m, even more preferably of at most 0.45 m or even 0.40 m.

[0127] In a further aspect, the method relates to a method for providing a removable display panel or upholstery on a display unit or system according to the preceding aspects of the invention, the display panel being a foldable sheet material, such as cardboard, and comprises a number of cutouts, essentially defining one or more "windows" with lateral flaps on the lateral edges of the windows extending inwardly to each other in these windows (not necessarily extending all the way towards each other). The windows match in width with the width of the display unit / system (distance between the side walls), and have a height that also matches with the height between the (subsequent) shelves of the display unit / system when unfolded. As the height between the shelves is settable in some embodiments, typically between a number of discrete settings, the display panels can be provided with different window heights (even different heights on the same panel).

[0128] The method involves setting up the display unit / system such that the openings defined by the shelves and side walls match the dimensions of the windows of the display panel. In a next step, the panel is positioned against the front of the display unit / system with the windows aligning with the openings, and folding the flaps inwards, in the openings, and against the inner side of the side walls. Side flaps of the display panel provided on the lateral edges of the display panel are folded against the outer side of the side walls of the (preferably substantially entire) display unit / system, and tucked into a clamping mechanism at the back side of the side walls (or even at the back side of the display unit / system), to keep it in place, and with it, the entire display panel.

[0129] In some embodiments, the lateral flaps can also be tucked into an internal clamping mechanism, or attached in a different way (for instance, adhesives).

[0130] It is understood that the lateral flaps and / or side flaps can be folded backwards before positioning the panel against the display unit / system, with the flaps being inserted in and / or aligned and clamped against the display unit / system when the display panel is brought into position.

[0131] DESCRIPTION OF FIGURES

[0132] Figures 1A-D show a display (unit) according to an embodiment of the invention in various stages of deployment.

[0133] Figure 1A shows the display (1) in fully collapsed form, wherein a top shelf (2) and bottom shelf (3) rest on top of each other via an optional clamping mechanism (13) on the lateral sides, which avoids that the system rest on the folded side walls (4), which are positioned in between the top shelf (2) and bottom shelf (3).

[0134] Figure IB shows the display (1) in partially unfolded form. The side walls (4) comprise of a first side wall section (4a), a second side wall section (4b) and a third side wall section (4c). The first and third side wall sections (4a, 4c) are fixedly connected to each other via an overarching bridge section (15), and are hingedly (7) attached to the top shelf (2) at their upper end, at the lateral edges of the top shelf (2). At the lower end of the first and third side wall sections (4a, 4c), they are slidably provided to the bottom shelf (3), without forming a fixed connection (although such an embodiment is envisioned, for instance by means of a track on the bottom shelf in which the side wall sections are secured and can move along). This allows them to fold freely, without being hampered in their movements.

[0135] The second side wall section (4b) is provided in between the first and third side wall section (4a, 4c), and between the bridge section (15) and the bottom shelf (3), and is hingedly (8) connected to both the bottom shelf (3) and is also hingedly (9) connected to the bridge section (15), and this way, also to the first and third side wall sections (4a, 4c). The bridge section (15) and the second side wall section (4b) are essentially of the same or similar height, at about half the height of the first and third side wall sections (4a, 4c) when they are not extended, resulting in a most efficient collapsed structure with maximal height and minimal occupied space.

[0136] The bottoms of the first and third side wall sections (4a, 4c) slide along the bottom shelf (3) automatically, as a result of the hinged connection (7) to the top shelf.

[0137] The telescopic extension means (6) can be seen housed within the first and third side wall sections (4a, 4c), and is provided with protrusions (11) that extend laterally in a biased positions (which ensures that they remain fixed), but can be retracted via a manipulable retraction mechanism (10) positioned at the bridge section (15), where the handle of a display would be positioned. The first side wall section (4a) comprises lateral openings (12) at different heights through which the protrusions (11) can be extended through to block the telescopic extension means (6) at specific heights.

[0138] Figure 1C shows the fully erected display (1), where the side walls (4) are in place and perpendicular to the top and bottom shelves (2, 3). The hinged connection (9) between the second side wall section (4b) and the bridge section (15) forms a 180° angle, and is preferably physically limited to such an angle, without allowing overfolding.

[0139] Figure ID shows the extended form of the display (1), wherein the telescopic extension means (6) are extended from the first and third side wall sections (4a, 4c). The back plate (5) can be seen as folded down from a hinged connection to the top shelf (2). In alternate versions, it can be folded up from the bottom shelf.

[0140] Figures 2A-2H show the unfolding process for a collapsed display system.

[0141] Figure 2A shows a fully collapsed version of the display system (18) with 6 subsequently stacked shelves (19), and is provided with (removable) wheels (20) at the bottom. The shelves are spaced by spacers (13) who also function as clamping mechanism (13) for holding furnishings, decorations, etc.

[0142] Figure 2B shows the display system (18) with the bottom level erected, according to the same principles as unfolding the display of Figure 1A-D, in this case similar to Figure 1C. This is achieved by lifting the second lowest shelf, thereby unfolding the side wall sections (4a, 4b, 4c) and bridge section (15) to their perpendicular position. In Figure 2C, the back plate (5) is folded down from against the second lowest shelf, to which it is hingedly attached. In Figure 2C, the hinged connection (7) of the first and third side wall sections (4a, 4c) is also visible, and specifically, this hinged connection (7) is formed between the telescopic extension means (6) and the abovelying shelf. The telescopic extension means (6) is secured in its unextended position in this case, by the protrusion (11) extending through the (invisible) bottommost opening (12) in the side wall sections (4a).

[0143] Figure 2D shows the fully erected display system (18) where all side walls (4) are erected perpendicular to the shelves, with the telescopic extension means (6) still being unextended and fixed within the first and third side wall sections (4a, 4c).

[0144] Figure 2E shows the manipulable retraction means (10), with which the protrusions

[0145] (11) can be moved out of their biased extended positions and retracted out of the openings (12), thereby allowing the telescopic extension means (6) to be slid out of the first and third side wall sections (4a, 4c) and extended. Once the desired height is achieved, the retraction means (10) can be released or similarly manipulated to allow the protrusions (11) to extend again when at the vertical position of an opening

[0146] (12), thereby fixing the telescopic extension means (6) in place at a desired height, as can be seen in Figure 2F where the bottommost telescopic extension means (6) is set to its highest position by having the protrusion (11) lock into (or out of) the topmost opening (12). This is repeated for each level of the display system, resulting in the fully extended form of Figure 2G.

[0147] Finally, the fully extended display system (18) can be furnished with decorations, such as a cardboard 'wrapper' (21) which can be clamped into the clamping mechanism (13) at each level.

[0148] Figures 3A-3E show the collapsing process for a fully extended display system (18). This follows the inverse steps of the above process of Figures 2A-2H. Figure 3A shows the fully extended display system (18). By manipulating the manipulable retraction means (10), the protrusion (11) can be biased out of the opening (12), allowing the telescopic extension means (6) to be retracted or slid into the first and third side wall sections (4a, 4c), as can be seen in Figure 3B. The back plate (5) is then folded against the topmost shelf of the level, as in Figure 3C, at which point the side walls

[0149] (4) are no longer blocked from folding inwards, as shown in Figure 3D.

[0150] Finally, when this is performed for each level, the fully collapsed display system as seen in Figure 3E is achieved.

[0151] Figure 4A shows the back plate when folded out from an upper lying shelf (via a hinged connection). The back plate (5) is kept in place via protuberances (17) at multiple heights to clamp the back plate (5) in place, to ensure it can block the folding inwards of the side walls (4). In Figure 4B, the display system is extended at said level, by extending the telescopic extension means (6) from the side wall sections (4a, 4c). As seen, the back plate (5) is still clamped by one of the protuberances (17) to ensure it stays in place.

[0152] Figures 5A-5E shows the manipulable retraction means (10), which can retract the protrusion (11), via a tensioned biasing means (22) laterally inward, or allow it to extend outward. This way, it can be retracted through openings (12) into the side wall sections (4a, 4c), allowing them to be moved vertically, and can be extended through the openings (12) to block the vertical position.

[0153] Figures 6A-C shows corner pieces which can be used to stack multiple displays or display systems. The corner pieces (14) can be slotted into a corner piece retention mechanism (16), comprising grooves and protrusions, to fix it into place at the corners of the (topmost) shelves, allowing multiple display systems to be stacked, as can be seen in Figure 6C.

[0154] Figure 7 finally shows the clamping mechanism (13), comprising multiple flexible clamps in which a cardboard or other panel can be slide or folded, to be held in place by the flexible clamp.

[0155] Figure 8 shows an exploded view of a modified embodiment of the display (or display system), wherein a base frame (23) is provided on which the wheels (20) can be mounted. A bottom shelf (2) is mounted on top of the base frame (23) and rests on this base frame (23). Weight sensors (24) are provided at each corner of the base frame (23), which are configured for weighing the structure mounted on top of the base frame (23), and all the contents thereon.

[0156] Additionally, in this figure, the telescopic extension means (6) are connected via a bridge (26), which is provided with a full handle (25). Figure 9 shows an alternative version of the locking mechanism, where the tensioned biasing means (22) is split into two parts on the front side of the display shelf / system, which are connected to each other while allowing rotation at this connection, allowing the protrusion (11) to be retracted through opening (12) into the side of the side wall sections (4a, 4c). Each of the two parts of the tensioned biasing means comprises a suspender (27) that ensures the biasing means can fold under the weight that is exerted thereon. The two-part version provides a stronger tensioned biasing means that can handle more weight with greater security. This two-part version is typically only present at the front, as this side of the shelf is usually populated more densely with content, bearing greater weight.

[0157] It should be noted that this two-part tensioned biasing means can also be implemented on the back side.

[0158] The present invention is in no way limited to the embodiments described in the examples and / or shown in the figures. On the contrary, methods according to the present invention may be realized in many different ways without departing from the scope of the invention.
