Description

PORTABLE DISPLAY SYSTEM BASED ON EXPANDABLE AND FOLDABLE MODULAR STRUCTURES FIELD OF INVENTION The present invention is related to portable display systems in general; in particular it refers to a portable display system based on expandable and collapsible modular structures, which offers versatility in the generation of multiple structural configurations, which can easily and quickly reconfigure in form and appearance, offering high structural strength and particularity of being able to interconnect in multiple modules, generating structures from simple to complex, offering functional, structural, use and application advantages for the exhibition of products and diverse advertising.

BACKGROUND OF THE INVENTION In the field of exhibitions and exhibitions, equipment called "Customs" or "to the media or over design" are common, in which wood coatings or finishes of paint, formica and other materials that are expensive and have impacts are used. negative for the ecology, as well as the immoderate felling of trees, the use of paints and solvents that damage the ozone layer.

The use of wood, agglomerates and wood derivatives, metal and steel parts, toxic aerosol paints and contaminants and hazardous waste such as thiner, benzine and other chemicals are commonly used, which represents a negative impact on the ecology; besides that its cost is very high, it requires tools for its assembly, as well as labor for the assembly and transportation as they are heavy structures.

The market of exhibitions has year after year a growth in the number of events annually and the main trend in these times is a frank rejection of traditional systems, as customers increasingly reduce and optimize their advertising budgets, in addition to they require avant-garde and flexible designs, easy to assemble, that avoid the use of wood and steel pieces, because the cost and time of execution of the assemblies is greater, with much waste of wood, excessive amounts of paint, skilled labor, etc..

The general tendency of the market is to use exhibitors with systems that use plasticized fabrics for the cleanliness of work and the economy that it represents, as well as the use of light structures, easy to assemble and that can be compacted for transportation.

In the state of the art are well-known display systems, portable and folding that are used in exhibition fairs, in advertising events, in shopping centers or other events where it is necessary a structure that allows to show and / or display products and / o to support advertising on canvas, rigid or semi-rigid panels.

Folding structures for display typically comprise a number of rigid members that are pivotally fixed in connecting means to generate folding and portable armored structures.

For example, in the Mexican patent base, the MX220539 patent was placed. Matthias Kemeny and Timothy L, O'neal filed on January 28, 2000 and granted on May 25, 2004 and claiming priority US 08/902344, which protects a portable display system (2) that includes a frame ( 4) foldable constituted of a plurality of box units (6) defined by separate cubes (12) with pivotable members (16) extending therebetween. In one aspect of the invention, an immobilization feature (26) is provided between the members (16) and the hub (12). In another aspect of the invention, a hook-type assembly (50) is described between the members (16) and the hub (12). More than one of these display systems (12) can be mounted together with a clasp (28) provided between adjacent outermost cubes (12) of two different systems (2). Also described is a cage (38), which allows the collapsible frame (4) to be assembled and disassembled into two separate packable parts. A button (22) is also described which allows the two parts of the display system (2) to be removably mounted together.

This system is complex and requires multiple components structurally difficult to assemble and does not allow the structure to generate multiple configurations in different shapes, sizes and arrangements.

In the United States was also located US Patent 4,473,986 of Theodore R. Zeigler of October 2, 1984, which was also requested and granted in Mexico with the number MX167902 already expired in Mexico, said patent discloses a structural module | that is capable of of being manipulated between a disassembled and a widened condition. and locked, comprising: a plurality of rod elements arranged generally parallel and in a bundle when the module is in disassembled condition a first group of plug means centrally associated with those ends of the rod elements projecting towards one end of the bundle, and a second group of plug means centrally associated with those ends of the rod elements, projecting towards the other end of the bundle at least some of the plug means of the first group that centrally connect some of the bundle elements. rod to each other, and at least some of the plug means of the second group that centrally connect some of the rod elements to each other, such that the plug means move in a predetermined pattern, when the module is manipulated to the enlarged condition, at least a pair of plug means comprises a plug means of the first group and a plug plug outlet of the second group that constitutes a split plug assembly, occupying a particular position in the pattern, and means for locking the pair of plug means to maintain the frame in flared condition.

This type of system does not offer the benefits offered by the system of our invention and does not allow multiple configurations or structural resistance.

US Pat. No. 4,992,212 of James N. Morgan of February 26, 1991, now obsolete, is also disclosed, which discloses a collapsible structure comprising a plurality of rotating masts connected pi metalically in a connector element comprising a quadrangular shape which in one The face comprises edges defining cavities on the four sides where the ends of the masts are pivotally connected and the center comprising a spring element. The plurality of masts intersect and are pivotally fixed at the intersection and their opposite ends are connected to other connector elements to form collapsible and expandable modules.

However, this folding structure does not offer the technical-structural benefits of our system.
