Description:
The present invention generally relates to assemblies of exhibitors for delivery and display of diverse products. More particularly, the invention relates to assemblies that are used in a structure that allows the packing of diverse products and facilitates transportation from the packing place to the place where products are displayed to the final consumer, without requiring that exhibition involve removing said products from the containing packing. 
     BACKGROUND OF THE INVENTION 
     Traditionally the packing has been understood as the covering that temporarily contains products, and serves mainly to group units of product in management, transportation and storage. 
     Technically packing is classified into container or primary packing, which is in direct contact with the product; secondary packing that groups a plurality of packaged products in order to form a bigger load, storage or transportation unit, with this secondary packing being where the tray, the box pallet, the display box, the carton, the wood box, the plastic box, the built-in rack box, the box with lid, the box with lid and bottom, the tabs box, the basket, the case, the plastic film and the paper sack, among others are comprised, whose structural configuration meets the requirements to be resistant, protect and preserve the product; and finally the tertiary packing comprising several secondary packing elements. 
     Within the context of the search for new proposals for packing and transportation of diverse products, multiple modifications and reconfigurations to the traditionally used secondary packing have been developed; a example is disclosed in the patent document U.S. Pat. No. 7,628,746 B2 to Aditya Varanasi, granted on Dec. 8, 2009, wherein a shipping container made of cardboard that becomes an exhibitor is disclosed and protected, using punched lines and previously cut openings that define together a line which circumscribes the cardboard container, which is in any location where the punched line crosses an edge of cardboard container or another punched line, providing a previously cut opening a clean separation. Furthermore, in this container-exhibitor no section of the perforated lines is parallel to an adjacent folding line. 
     Another document of interest in relation to the inventions is the U.S. Pat. No. 7,607,566 B2 to Nicholas A. Philips and Jeffrey A. Smith, granted on Oct. 27, 2009, in which is being disclosed a container for shipment and exhibition of products and its associated containment space, wherein the containment space of the container includes a plurality of side panels, lower and upper panels, that are erected within an annex shipping container, forming in some of the side and upper panels, removable outward window panels. 
     As far as it is concerned, the U.S. Pat. No. 7,584,854 B2 to Ashok V. Chandaria, granted on Sep. 8, 2009, protects a shipping and display assembly for a plurality of complementary primary and secondary products such as wrapping paper and adhesive tape, wherein the assembly includes a box that has a first section and a second section that are connected each together for shipping and are detachable to display products. The first section includes a first compartment to support and display the primary products, and a second compartment to support and display the secondary products. The second section of the exhibition assembly retains primary and secondary products within the first and second compartments during shipment and is removed when products must be displayed. 
     Furthermore, aside from the vast examples included in the technical field to which the present invention belongs is found in the U.S. Pat. No. 7,472,819 to Richard G. Wachter, dated on Jan. 6, 2009, wherein was granted protection to a container for shipment and exhibition whose retaining area is defined from a folding material, so that when the container is finished it includes a visible section on the front panel; likewise the side panel and the rear panel have both internal and external shapes, while the side panel includes at least one partial intermediate side panel, so that the side multi-panels and the rear panel give the necessary strength and stability to the container. 
     According to the state of the art previously discussed, most containers for packing, shipping, and exhibition of products, including the most novel, are made from a single concept which consists of preparing a folding material that covers and protects in it all the subject products, so that after the transportation process, i.e. when there is no latent risk of damaging the products, some parts of said folding material are removed forming exhibition windows. 
     The above mentioned, seems to be a practical and economic alternative solution for packing, shipping, and exhibition of diverse products; however the fact of the vast majority that the containers until now known, define their structural strength from the product characteristics they contain must be considered, thus, it is logical to understand that a sheet of folding material, which mostly is cardboard, is not enough to protect the products comprised inside, limiting their real application to only keeping together the products desired to be transported, this could be achieved with the simple application of a transparent plastic film around the products that is desired to be kept together. 
     Besides the above, there is a second disadvantage when the containers of the state of the art are used, and this becomes real when it is necessary to remove certain parts comprising them in order to be able to exhibit the products contained therein, i.e., to open the exhibition windows allowing the end-user to appreciate the contained products, which is double work since the container first must be assembled for packing and transportation of the products and second, the parts of the container that allow the display of products must be removed. 
     While the fact of detaching some segments of the container for open exhibition windows could not be complex since such sections are previously cut, it is a problem that once those segments are removed from the container, it will lose structural strength characteristics, and worse greatly limit their ability to safely transport the products contained, thus becoming a container that can be used only once, i.e. a disposable container. 
     Due to aforesaid arises the need for a enhanced structure for packing, transportation and display of products that provides a greater structural strength, reusable, easy to assemble, and does not require any modification from the packing stage to the exhibition of products to the end user. 
     In fact, a first attempt to achieve the above is disclosed in patent MX269583, owned by the same inventor of the enhanced structure object of the present application, which discloses and protects a display packing easily collapsible, characterized in that it is comprised of a lower frame shaped from four horizontal angular elements related to the horizontal plane inward and at the bottom, attached in the ends by fittings comprising horizontal planes and vertical planes, the fitting remaining inside the apex and joining the vertical planes of the horizontal angular elements by attaching means fixing said planes to the vertical planes of the fittings and the horizontal planes of the horizontal angular elements fixed by attaching means to the horizontal planes of the fitting; a fitting is located in each corner of the frame; each fitting has two segments, the inner one separate from the vertical plane of the horizontal angular element, remaining a slit where will slide an end of an angular vertical element with slots in order to surround one of the attaching means, and a segment abutting with the vertical plane of the horizontal angular element; each corner is provided with a vertical angular element and in its free ends are inserted the corners of an upper frame with the same structure of the lower; finally the secondary packing includes diagonal tensors in each of the diagonals of the surfaces formed by vertical angular elements and horizontal angular elements. 
     Even though the above described display packing meets the sought requirements of structural strength, reuse, and display of products to the end-user without structural modifications, as a result of various technical analysis processes, it has been possible to arrive at a meaningful and innovative improvement of the features which comprises it, particularly the structural shape of the upper and bottom frames, the attaching elements and the arrangement of the tensor elements, giving rise to a new enhanced structure for packing, transportation and display of diverse products, with which are intended as follows: 
     OBJECTS OF THE INVENTION 
     It is an object of the present invention, to provide a enhanced structure for packing, transportation, and exhibition of diverse products, that allows packing of large volumes of products. 
     Another object of the present invention is to provide a enhanced structure for packing, transportation and display of diverse products that based on its structural strength characteristics, allows the transportation of large volumes of products, safely, efficiently, and without disarrangement or damage to the transported products. 
     Another object of the present invention is, to provide a enhanced structure for packing, transportation, and display of diverse products, that allows display of the products it contains from the time of packing to the end-user presentation, without modification of shape, structure, or position of the structure implied. 
     Another object of the present invention is to provide a enhanced structure for packing, transportation and display of diverse products that based on structural elements that make it up is easy to assembly and disassembly. 
     Another object of the present invention is to provide a enhanced structure for packing, transportation, and display of diverse products in which the structural elements that make it up practically can be replaced when they are damaged, enabling reuse of the structure. 
     Yet another object of the present invention is to provide a enhanced structure for packing, transportation and display of diverse products made from lightweight materials that allow easy handling of the frame. 
     SUMMARY OF THE INVENTION 
     The present invention relates to a novel enhanced structure for packing, transportation and display of diverse products which allows transporting large volumes of products reliably and efficiently from the point of manufacture to the point of sale, structure that gives various competitive advantages related to the containers already known in the market, with the most important being, the solid structural stiffness which comes from a quick and reliable assembling of the whole structure, which is achieved from the configuration of the fastening gussets that attach the upper and lower frames with the support and containment side posts, and the configuration of the structural profiles that make up both the upper frame and the bottom frame. 
     A second advantage of the enhanced structure for packing, transportation, and display of diverse products, is reflected in that it is practical with the help of the fastening gussets to dispose of at least a pair of diagonal tensors in each of the four sides of the structure, which is achieved substantially increases structural strength.

     DETAILED DESCRIPTION OF THE INVENTION 
     According to what is illustrated in  FIGS. 1 and 2 , the enhanced structure for packing, transportation and display of diverse products  100 , object of the present patent application, hereinafter called structure  100 , is comprised of a first upper rectangular frame  200  and a second rectangular bottom frame  300  which are kept together by means of four support and containment side posts  400 , disposed in each corner of said upper  200  and bottom  300  frames, where the perimeter dimensions of the frames define in combination with the length dimensions of the four support and containment side posts  400 , the volume of the structure  100  and therefore their ability for containment, transportation and display. Each one of the support and containment side posts  400  is a straight post of “L” shaped cross-section and is attached to a corner of the upper frame  200  by means of a first fastening gusset  500  and to a corner of the lower frame  300  by means of a second fastening gusset  600 , wherein each one of the first fastening gussets  500  have the same structural shape than the second fastening gussets  600 , the first ones differentiated from the second ones fastening gussets with the purpose of identifying only that while some of them allow to hold the upper end of a support and containment side post  400  to a corner of the upper frame  200 , the other ones allow to hold the lower end of said post  400  to a corner of the lower frame  300 . 
     In addition and with the object of strengthening the load capacity of the structure  100 , tensor elements  800  have been disposed alternately between the first fastening gussets  500  and the second fastening gussets  600 , these in combination defined two diagonal tensors intersecting in “X” shape, for each one of the front, right side, left side and rear faces of the structure  100 . 
     Thus, once the structure  100  has been built from each one of the elements above defined, it is placed on a pallet  700 , by means of which it is possible to handle it with a fork lift (not illustrated). 
     Both the upper frame  200  and the bottom frame  300  of the structure  100  have the same shape, and each one is conformed from a pair of structural profiles  210  bent in square shape and attached in their free ends; thus, in order to avoid unnecessary repetition, suffice it to say that once assembled a frame with two profiles  210 , as the frame shown in  FIG. 4 , the upper or bottom position of the same depends on the position of the structure  100 , with up-down orientation. 
     As illustrated in  FIGS. 3 ,  4 A and  4 B, each of the structural profiles  210  comprises an “L” shaped cross-section, in the vertical wall of which and beyond of its central part, inclined to its left end, a folding section  211  is shaped from a plurality of weakening lines and the removal of a portion of said vertical wall material, so that together facilitate to fold in this section, the structural profile  210  up to reach an angular position of 90° between the sections of the profile  210  defined before and after of the folding section  211 . 
     Complementarily to the previously defined folding section  211 , in the horizontal wall of the structural profile  210  has been made the removal of a portion of material, so that such removal of material gives rise to a first section of horizontal wall  212  and a second section of horizontal wall  213 , with each of said horizontal wall sections having at its ends abutting with the folding section  211 , a stepped termination which allows a perfect coupling of both horizontal wall sections when the 90° fold of the structural profile  210  is made. 
     Also each one of said first  212  and second  213  horizontal wall sections have in each end abutting with the folding section  211  and close to its part abutting with the vertical wall, a retention slot  214  through which it will be possible to secure a fastening gusset  500  that will attach a corner of the shaped frame with a support and containment side post  400 ; meanwhile in its terminal ends each one of these horizontal wall sections also has a stepped termination and two retention slots  214  that allow coupling with the horizontal terminal ends of a second structural profile  210  such as that shown in  FIG. 4C , so as to conform in this manner one of the frames of the structure  100 . Furthermore, each one of the terminal ends of the vertical wall is shaped so that there is a small flange  215  through which and in combination with the retention slots  214  shaped in the horizontal wall of each one of the structural profiles  210 , it is possible to attach by means of a fastening gusset  500  the terminal ends of two structural profiles  210 , thus forming one of the two frames that make up the structure  100 . 
     In a preferred embodiment of the invention, the structural profiles  210  and the support and containment side posts  400  are produced from cardboard. 
     Insofar as the fastening gusset  500  attaching each corner of the upper  200  and lower  300  frames of the structure  100  with the support and containment side posts  400 , and even allows the attachment of the two structural profiles  210  from which, each one of said frames is conformed, according to what is illustrated in  FIGS. 5 to 7 , said fastening gusset  500  in addition to attach elements, provides for a greater resistance to the structure  100  and allows it to set up quickly and reliably, making it possible to replace damaged parts for the reuse of said structure  100 ; it is shaped from a moulded one piece, through which a rounded main wall  501  is defined, whose side ends are projected towards the rear part with a fold in “U” shape, in order to conform a left insertion paddle  502  and a right insertion paddle  503 , finishing each one of said insertion paddles with a portion of material which is projected outwards and allowing easy arranging of the support and containment side posts  400  of “L” shaped cross-section into the interior of the space defined between each one of said insertion paddles and the rounded main wall  501 . 
     At the medium part of the rounded main wall  501  of the fastening gusset  500 , a pair of slots  504  have been conformed, which in combination with a pair of anchors  505  disposed for such purpose in the right and left upper ends of said rounded main wall  501 , allow the placement and retention of the tensor elements  800  which in particular are diagonal tensors intersecting in “X” shape for each one of the front, right side, left side and rear faces of the structure  100 . 
     In a first preferred embodiment of the invention, is envisioned that the anchors  505  are defined from bolts, however, the use of bolts should not limit the scope of the invention, since as shown in  FIG. 8 to 10 , said anchors  505  can be in a second embodiment of the present invention defined from hooks. 
     In a preferred embodiment of the invention, the fastening gusset  500  is made preferably of metal, plastic, nylamid, laminated cardboard, or polymers. 
     Once the elements integrating the structure  100  are defined, it is time to address the aspect of its assembly, prior to which, it is important to bear in mind that what is described below is intended for the attachment of the four corners integrating one of the two frames with the support and containment side posts  400  through a fastening gusset  500  because of which, in order to achieve the total integration of the structure  100 , must be repeated the described action, four times regards to the upper frame  200  and four times regards to the bottom frame  300 . 
     As may be noted from  FIGS. 11 to 13 , once two structural profiles  210  are folded and the upper frame  200  is formed, the support and containment side posts  400  are placed in each corner of said frame, in order for the retention slots  214  remain arranged so that the left  502  and right  503  insertion paddles of the fastening gusset  500  may be inserted, so that, primarily through the gusset  500  the two intermediate ends of a structural profile  210  remain attached or the two terminal ends of two structural profiles  210  that are attached, and secondly, taking in account the design of the fastening gusset  500  when the left  502  and right  503  insertion paddles are inserted in the retention slots  214 , the post  400  are fixed to the upper frame  200  and thus resulting in the structure  100 . 
     Finally, depending on the embodiment, the tensors  800  are attached to the bolts or hooks defined by the anchors  505  of the fastening gusset  500 . 
     In another preferred embodiment of the present invention, and in accordance with what is illustrated in  FIGS. 14 and 15 , a pallet  900  supporting the structure  100 , is configured so that it comprises four corner wedges  901  receiving directly four support and containment side posts  400 , i.e. the four corner wedges  901  of the pallet  900 , defining together the bottom frame of the structure  100 , so that now the structure  100  and the pallet  900  merge together to shape a single unit of packing, transportation, and display of diverse products, which simplifies the assembly process, because it prevents the bottom frame assembly of the structure  100 , without modify at all the other elements configuration that make up the structure or limit the resistance or functionality characteristics defined for the first embodiment of the invention.
