## Background
This application claims priority to PCT patent application PCT/IB2005/002083, filed Jun. 20, 2005 and incorporates this application in its entirety by reference thereto.
FIELD OF THE INVENTION
The present invention relates to techniques employed in the manufacture and design of furniture, showcases and displays that offer products and services and, in particular, the invention relates to a demountable display module which is stored in the form of a briefcase and production method thereof.
BACKGROUND OF THE INVENTION
In many places where public gather for the acquisition and exposure of products and services, such as fairs, conventions, information centers and so on, there is a need to use furniture and counters to approach the public to the suppliers and introduce them to their products. In this regard, there exists an important variety of such furniture, e.g. wooden-made, metallic, furnished with shelves, partitions; in general terms, though, they are bulky, difficult to handle and transport thereof results in hardships since they take up a lot of space.
One art-known solution to such problems has involved the creation of carton foldable furniture and counters. Nevertheless, their structural rigidity is poor and, furthermore, it is impossible for one person to lean thereon. In addition, this type of carton-made furniture lacks of an outstanding aesthetical appearance, which is an important factor to achieve a commercial impact of the product or service being supplied.
There also exists furniture with countless panels, rods and posts that cooperate to each other; however, assembly thereof is time-consuming and the pieces to be assembled are too many.
Despite the above, there are exhibition devices that have been broadly the base and a board above the cover. In this type of counters, the board helps to identify the name of the supplier or the product being offered while the supplier is located behind the counter to attend to the customers approaching the module.
One of such modules is disclosed in Mexican patent No. 212,227, which most significant advantage is that the module elements can be disassembled and stored in the form of a briefcase. In the module of said patent, a hinged shelf is included within the base. Nevertheless, one issue with such module is that the shelf and the post sections supporting the board are movable within the base when they are stored therein. In addition, when the module is assembled, the posts and board are scarcely stable; furthermore, the pins employed to close the cover go outside and, therefore, are prone to failures.
The module of the above-mentioned patent was restructured in Mexican patent No. 225, 710, wherein the most significant changes are the inclusion of 45° cuttings between the post sections and a second shelf that runs on a rail, in addition a support to secure the post sections within the second shelf was included. In spite of such modification, the board continues being unstable since it sways over the cover. Furthermore, the shelves frequently fall off their horizontal position because at their free side ends the shelves are secured only by pressure between the side panels of the base. Also, the cover (body of the briefcase) faces strength issues when the module is stored therein; particularly, the cover is prone to breaking when being handled and hauled; more specifically, it has been observed that when the cover is knocked at its bottom, the impact is passed on to the side faces, reaching the lid and breaking it. It is desirable to improve the strength of the cover, taking into account that it is the most critical piece when the module is stored in the form of a briefcase.
Another issue is the generation of scratches on top of the base panels every time the bases is taken out of or put into the cover. Likewise, it has been observed that when the base is inside the cover, the former moves upwards and downwards, resulting in deterioration of the base.
On the other hand, the above Mexican patents do not address the manner in which such module may be manufactured. However, give the acceptance of such product in the market; it is desirable to have a sequential and logical manufacturing process that maximizes the usage of materials from which the essential elements of the display module are made.
SUMMARY OF THE INVENTION
Pursuant to the above, the purpose herein has been to overcome the drawbacks of prior art display modules that are stored in the form of a briefcase through the development of a novel structural relationship among the essential elements thereof, as well as through the addition of new elements that help work out such prior art issues.
The display module that is stored in the form of a briefcase of the present invention comprises: a base formed by panels hingedly connected one next to the other such that said base has a “collapsed” and a “stand up” position, wherein said panels define at the base: a first side panel, a first front panel perpendicular to the first side panel, a second front panel adjacent the first front panel and a second side panel perpendicular to the second front panel and opposed to the first side panel; each of said panels being formed by a rectangular frame and a sheet that covers and is coupled to the frame; on the other hand, when the base is in the “collapsed” position, each side panel is housed inside the frame of the front panel to which it is coupled and both front panels face against each other.
As another essential element of the module of the present invention, there is provided a cover demountably coupled on top of said base when the latter is in its “stand up” position; said cover has the shape of a rectangular housing with a upper face, two side faces, a front face, a lid with a handle coupled to the upper face and opposed to the front face, lower tabs extending from the front face, the side faces and the lid towards the interior of the cover in parallel with the upper face, a pair of cavities on top of the upper face and means for opening and closing the lid.
Furthermore, other module elements are a pair of posts, each of them being detachably mounted by its lower end to the frame of one of the side panels and crossing said cover through one cavity thereof the cover is mounted on top of said base; the posts being formed by a lower section and an upper section that are coupled one to the other. In this regard, it is important to point out that the coupling of the posts to the frame of each side panel substantially improves the stability of said posts; i.e., the frames of the side panels and the post form a type of framework when coupled together.
The present invention further comprises as another critical element a board demountable joined to the upper end of each of the posts.
The demountable display module of the present invention also comprises a first shelf located between both side panels and elevated with respect to the lower edge of said base in its “stand up” position; said first shelf is slidably joined by one of its side ends to the first side panel and is formed by a first rectangular shelf frame and a first shelf sheet that covers and is attached thereto; said first shelf is housed inside the frame of the first side panel when the base is in its “collapsed” position. Regarding the above, the union of the first shelf to the base facilitates the storage of the first shelf; additionally, pieces used are less complicated than those of the prior art are used.
Inside the base, the module also comprises a second shelf located between both side panels and separated underneath said first shelf; said second shelf is hingedly attached by one of its side ends to the second side panel and is formed by a second rectangular shelf frame and a second shelf sheet that covers and is attached thereto, said second shelf is housed inside the frame of the second side panel when the base is in its “collapsed” position.
The present invention also provide first means for supporting the first shelf in a horizontal position when the base is in its “stand up” position, the first supporting means also being also useful for securing the second shelf in a vertical position when the same is housed inside the frame of the second side panel; there are also provide second means for supporting the second shelf in a horizontal position when the base is in the “standing” position, the second means also being useful for securing the first shelf in a vertical position when the same is housed inside the frame of the first side panel. These first and second supporting and securing means prevent the shelves from losing their horizontal position when they are located between the side panels, and they also secure the shelves when the base is collapsed; thus, the shelves suffer no damage during haulage of the module.
In order to demount and store the module elements in the form of a briefcase, the board is demount off each one of the posts, which in turn are also demount from said cover and the latter ultimately from the base, in which both the first shelf and the second shelf are housed inside the frame of the side panel to which they are attached to; wherein the lower and upper sections of each post uncouple to become housed inside the second shelf frame; thus, the board is placed over the already housed first shelf and the side panels with their respective shelf are housed inside the frame of the front panel to which they are joined; afterwards, the front panels are faced against each other, thereby resulting in the “collapsed” position of said base that is being introduced through the lid of said cover that functions as a container body to store and haul all the module elements in the form of a briefcase.
In one aspect of the present invention, a process for the manufacture of the module is provided, which comprises the following steps:

    
    
        a) extruding a first tubular profile;
        b) cutting said first tubular profile into a first group of six sections, each one of them with a predetermined length;
        c) building from the first group of six sections a frame for each of the two side panels of the base, a frame for each of the two front panels of the base, a first shelf frame and a second shelf frame;
        d) attach a sheet to each one of the frames formed in the previous step, thereby achieving a first side panel, a second side panel, a first front panel, a second front panel, a first shelf and a second shelf;
        e) mounting the first shelf by one of its side ends between the lateral sides of the frame of the first side panel, such that the first shelf becomes slidably attached;
        f) mounting the second shelf by one of its side ends to the lower side of the frame of the second side panel, such that the second shelf becomes hingedly attached;
        g) fixing first supporting and securing means over the internal surface of each of lateral sides of the frame of the second side panel;
        h) fixing second supporting and securing means over the internal surface of the lower side of the frame of the second side panel;
        i) assembling the first side panel with the first front panel; the first front panel with the second front panel; and the second front panel with the second side panel, such that the panels hingedly attach one next the other, thereby obtaining the base of the module;
        j) thermal-bending a first plate to obtain the main body of the cover in one single piece, said main body including the upper face, the side faces, the front face and the tabs that extend from the side faces and the front face of the cover;
        k) thermal bending a second plate to obtain the lid and the lower tab in one single piece, extending therefrom;
        l) assembling the lid obtained in the previous step with the main body, thereby obtaining the cover with its lid;
        m) extruding a second tubular profile and a third tubular profile, wherein the third tubular profile has reduced diameter than that of the second tubular profile;
        n) cutting both the second tubular and the third tubular profiles, thereby obtaining therefrom: a second group of six sections, each one having a predetermined length; and a third group of six sections, each one having a predetermined length;
        o) inserting and pasting each of the six sections of the third group from the third tubular profile inside one end of one of the six sections obtained from the second tubular profile, such that each section of the third group projects from the end where each section is inserted into, thereby obtaining by the end of the step the upper and lower sections of each of the two posts and each of the two coupling bases of the board;
        p) pasting the coupling bases obtained in the above step to a sheet, thereby obtaining the board; and
        q) packing the respective base, the post sections and the board obtained in steps (l), (o) and (p) inside the cover obtained in step (i), so that by the end of this packing step the demountable display module is obtained in the form of a briefcase.
    
    


The main advantage of this process is that the materials used are maximized throughout its steps, the process only requiring profiles, sheets and hinges; i.e., material wastage is avoided.
From the above, it can be mentioned that an object of the present invention is to provide a demountable display module that can be stored in the form of a briefcase, wherein the board and the posts hold perfectly stable when the entire module is mounted.
Another object of the present invention is the provision of a demountable display module that can be stored in the form of a briefcase, wherein the shelves thereof are adequately supported in a horizontal position when the module is mounted, and wherein the shelves must remain in a vertical position when the module is stored in the form of a briefcase.
A further object of the present invention is to provide a demountable display module that can be stored in the form of a briefcase, wherein the cover must withstand shocks and accidents when the entire module is stored.
One further object of the present invention is to provide a process for the manufacture of a demountable display module that can be stored in the form of a briefcase, wherein throughout the procedural steps the materials used are maximized.

DETAILED DESCRIPTION OF THE INVENTION
With reference to the accompanying drawings and, more specifically, to FIGS. 1-3 thereof, a demountable display module 100 is shown, said module is stored in the shape of a briefcase. The demountable module 100 comprises a base 20 formed by panels hingedly attached one next to the other, such that said panels define in the base 200: a first side panel 201; a first front panel 202 perpendicular to the first side panel 201; a second front panel 203 adjacent the first front panel 202; and a second side panel 204 perpendicular to the second front panel 202 and opposed to the first side panel 201. Each of said panels 201, 202, 203 and 204 is respectively comprised of a rectangular frame 205a, 205b, 205c and 205d, as well as a sheet 206a, 206b, 206c, 206d that covers and is attached to the corresponding frame. The construction of the base by means of hinged panels allows for a “standing” position, as seen in FIGS. 1-3, and a “collapsed” position that will be explained later.
The demountable display module 100 also comprises a cover 300 demountably coupled over the upper edge of the base 200. In FIGS. 1-3, it is observed that the cover 300 is shaped like a rectangular housing with an upper face 301, side faces 302 and 303, a front face 304 and a lid 305 hingedly attached to the upper face 301 and opposed to the front face 304. The lid 305 includes a handle 306 to grasp the entire display module 100 when it is demounted and stored in the form of a briefcase. Additionally, the upper face 301 includes a pair of cavities 307, which can be distinguished more clearly in FIG. 3.
In FIGS. 1-3, it is seen that the demountable display module 100 further comprises a pair of posts 400, each of them demountably coupled by its lower end to the frame 205a or 205d of one of the side panels 201 and 204. In this coupling, each of the posts 400 crosses the cover 300 through one of the cavities 307 when the cover 300 is mounted on the base 200. Likewise, in FIG. 3, it is seen that each of the posts 400 is formed by a lower section 401 and an upper section 402 that are coupled to each other.
From FIGS. 1-3, it is also seen that the display module 100 also has a board 500 that is demountably joined to the upper end of each of said posts. 400. On the board 500 graphic media may be placed, such as signs and legends to identify the services and products of the supplier that is using the demountable display module 100.
By referring to FIG. 2, it can be seen that within the base 200 there exists a first shelf 600 located between both side panels 201 and 204 and raised in respect of the lower edge of the base 200, approximately half way thereof. The first shelf 600 is slidably attached by one of its side ends to the first side panel 201 and is formed by a first rectangular frame shelf 601 and a first shelf sheet 602 that cover and is attached to the frame 601. When the base 200 folds and brought to its “collapsed” position, the first shelf 600 is housed inside the frame 205a of the first side panel 201; the latter will be further described later. In the embodiment described, the first shelf 600 is placed at the base 200 with its first shelf frame 601 facing upwards, with the result that the first shelf frame 601 works as a barrier to prevent the articles placed on top of the first shelf 600 from falling off to the ground.
Similarly, the demountable display module 100 comprises a second shelf 700 located between both side panels 201 and 204 and spaced downwards of said first shelf 600 approximately at the lower part of said base 200. The second shelf 700 is hingedly attached by one of its side ends to the second side panel 204 and is formed by a second rectangular shelf frame 701 and a second shelf sheet 702 attached over said frame 701. When the base 200 is brought to its “collapsed” position, the second shelf 700 is housed inside the frame 205d of the second side panel 204, which will be explained hereinafter. In the embodiment described, the second shelf is placed at the base 200 with its second shelf frame 701 faced downwards; such orientation will allow the lower section 401 and the upper section of the posts 400 illustrated in FIG. 3 to be housed within the second shelf frame 701 when it is desired that the entire display module 100 be demounted and stored.
Reference is now made to FIGS. 4 and 5 that respectively show a rear view and a top plan view of the base 200 in its “standing” position. From these figures, it can be mentioned that the first side panel 201 is hingedly attached to the first front panel 202 by means of a first hinge 211 that is fixed between the adjacent lateral sides of the frame 205a and the frame 205b of both panels 201 and 202, such that the first side panel 201 can outwardly rotate and inwards of the base 200 over said first hinge 211 to become housed within the frame 205b of the first front panel 202. In FIG. 5, part of the first hinge 211 and the lower edge of the side of the frame 205b from the first front panel 202—where the first hinge 211 is attached—are represented by a dashed line, since they are hidden. It is important to point out that the first hinge 211 runs downwardly over said adjacent lateral sides and that the frame 205a of the first side panel 201 has a smaller size than that of the frame 205b of the first front panel 202, as seen in FIG. 4; this size differential allows for the first side panel 201 to be housed inside the first front panel 202.
Furthermore, the first front panel 202 is hingedly attached to the second front panel 203 by means of a second hinge 212 that is fixed over the respective adjacent lateral sides of the frame 205b and of the frame 205c of both front panels 202 and 203. The second hinge 212 runs downwards over said sides and is opposed to the sheet 206b and to the sheet 206c of each of the front panels 202 and 203 respectively, such that the sheets 206b and 206c make up a continuous surface towards the front of the demountable module 100, as shown in particular in FIG. 1. Having a continuous surface prevents the printed or graphic media placed on the front panels 202 and 203 from warping or becoming obstructed, one feature desired by suppliers that offer their products in the demountable module 100. In FIG. 5, the lower edge of the adjacent lateral sides of the frames 205b and 205c are represented by a dashed line in order to appreciate in further detail the arrangement of the second hinge 212. As another important feature, the frames 205b and 205c of both front panels 202 and 203 have the same size (refer to FIG. 4).
From FIGS. 4 and 5, it can further be mentioned that the second side panel 204 is hingedly attached to the second front panel 203 by means of a third hinge 213 that is fixed between the respective adjacent lateral sides of the frames 205d and 205c of the second side panel 204 and of the second front panel 203, such that the second side panel 204 may rotate inwards of the base 200 over said third hinge 213 in order to be housed within the frame 205c of the second front panel 203. In FIG. 5, part of the third hinge 213 and the lower edge of side of the frame 205c from the second front panel 203—where the third hinge 213 is secured—is represented by a dashed line. It is important to mention that the third hinge 213 runs downwards over said adjacent lateral sides and that the frame 205d of the second side panel 204 has a smaller size than that of the frame 205c of the second front panel 203; said difference allows the second side panel 204 to be housed within the second front panel 203.
In FIG. 4, the first shelf 600 can be seen with its first shelf frame 601 facing upwards, which as mentioned above allows the creation of a barrier for the products placed on top of said first shelf 600. This same FIG. 4 also shows the second shelf with its frame 701 facing downwards.
Another important feature that can be appreciated in FIG. 5 is that both the frame 205a of the first side panel 201 and the frame 205d of the second side panel 204 include an aperture 207 facing upwards, said aperture 207 has the purpose of housing the lower end of each of the posts 400 shown in FIG. 1. In particular, in FIG. 5, it can be seen that the frame 205a and the frame 205d of said first and second side panels 201 and 204 preferably include said aperture 207 at its upper and rear corners. This structural relationship for the coupling of the frames 205a and 205d with each of the posts 400 substantially enhances the stability of the board 500 (see FIG. 1) versus the board stability of the Mexican patents 225,710 and 212,227.
Further describing the structure of the frames 205a and 205d, which are part of the side panels 201 and 204 respectively, it can be mentioned that they are identically built one to each other. To delve into this aspect, reference is made to FIG. 6, which shows the frame 205a from the first side panel. The frame 205a is shown unfolded and extended and built be means of a first section 221 of a tubular square profile in cross section, which includes a first group of three triangular cuttings 222 separated of each other. Additionally, it is observed that each cutting 222 encompasses three of the profile's surfaces. On top of each cutting 222, the first section 221 is folded to shape the two lower corners of the frame, as well as the upper and frontal corners, while the upper and rear corners are formed by the perpendicular union of the ends of said first section 221, such that one of said ends of the first section 221 defined said aperture 207.
Furthermore, in FIG. 6, it is seen that the frame 205a of the first side panel has a slot 612 included at the inner surface of each lateral side; this slot 612 has an important function for the first supporting and securing means described hereinbelow, and the slot 612 is not included in the frame of the second side panel.
Regarding the frame 205b of the first front panel 202, the frame 205c of the second front panel 203, the first shelf frame 601 and the second shelf frame 701 (see FIGS. 1 through 3), it can be mentioned that these have an identical construction. In order to describe this construction particular reference is made to FIG. 7, which shows the frame 205b of the first front panel that is built by means of a second section 223 of a square tubular profile in cross section, which is provided with a second group of three triangular cuttings 224 separated from each other. Each cutting 224 encompasses three of the surfaces of the profile and the second section 223 is bent over each cutting in order to form three of the corners of the frame 205b. Likewise, the second section 223 includes a first diagonal cut 225 at 45° in each of its ends, which for the remaining corner of the frame 205b when joined together. It is important to point out that the first shelf frame and the second shelf frame (FIG. 2) have the same construction as that described for the frame 205b of FIG. 7.
Now it is convenient to make reference to FIGS. 8 through 13, so as to describe the structural relationship between the base 200 and the first shelf 600 and the second shelf 700, as well as to describe other important elements of the present invention.
As previously established, the first shelf must slidably attach, by one of its side ends, to the first side panel through sliding means. In the preferred embodiment being described, the sliding means employed include: a pair of U-shaped sliding bases 610 in cross section, each one of them being inside a lateral side of the frame 205a of the first side panel 201; a pair of shafts 611, each one being attached to by one of its ends to one of said sliding bases 610 and by the other end each shaft 611 is attached over the external surface of the corners of a side end of the first shelf frame 601. The latter can be seen in particular in FIG. 8, which is a cut-away alongside the line A-A′ of FIG. 4, and is further noticeable in FIG. 9, which is an expanded view around the area in circle “C” of FIG. 8.
From FIG. 9, it can be mentioned that each sliding base 610 with its shaft 611 runs downwardly alongside the slot 612 included in the internal surface of each lateral side of the frame 205a of the first side panel 201. Therefore, at the lowest part of each slot, said first shelf 600 rotates over the shaft 611 to be placed horizontally between the side panels 201 and 204 of the base when in the “standing” position, such as the first shelf represented in FIG. 8.
Now, to house the first shelf 600 within the frame of the first side panel 201, the first shelf 600 rises over each slot 612 and then rotates over the shafts 611 to be housed in a vertical position inside the frame 205a of the first side panel 201. In this regard, the first shelf 600 already housed in the frame 205a of the first side panel 201 can be observed in FIG. 12. From this figure, it is important to point out that the sliding means also include an abutment 613 attached to the internal surface of the upper side of the frame 205a of the first side panel 201 to restrict the upward movement of the first shelf 600 over the slots 612, which along with sliding bases 610 and the shafts 611 are represented by dashed lines in FIG. 12 since they are hidden.
By reference to FIG. 13, which shows a rear view of the second side panel 204, it can be mentioned with respect to the second shelf 700, that the latter is hingedly attached to said second side panel 204, for that purpose a fourth hinge 214 is used that is fixed over a lateral end of the frame 205d of the second side panel 204 and over one end of the second shelf frame 701, such that the second shelf 700 can rotate downwardly over said fourth hinge 214 to be placed horizontally between the side panels 201 and 204 of the base 200 when it is in its “stand up” position, just like the second shelf 700 represented in FIG. 11. Turning again to FIG. 13, the second shelf 700 also rotates on the fourth hinge 214 in order to be housed in a vertical position inside the second side panel 204.
On the other hand, one of the main features of the present invention is the provision of firs means for supporting the first shelf in a horizontal position when the base is in the “stand up” position, said first means also being useful for securing the second shelf in a vertical position when housed inside the second side panel.
In the preferred embodiment described, said first supporting means are a first pair of brackets 800 that are attached over the internal surface of the lateral sides of the frame 205d from the second side panel 204 and faced to each other. In addition, the brackets 800 include a cylindrically-shaped stem 801 that vertically extends upwardly (see FIG. 13).
The manner in which the brackets 800 support the first shelf 600 in a horizontal position can be seen in FIGS. 8 and 10, wherein it is noteworthy that each bracket 800 has an adequate surface so that the corners of the first shelf frame 601 abut against the brackets 800; furthermore, the first shelf frame 601 includes a first pair of holes at the lower surface of its free side end adjacent the second side panel 204 in order to receive the stem 801 from each bracket 800. Particularly in FIG. 10, part of one of the brackets 800 that supports the first shelf frame 601 is represented by a dashed line; in this same figure a lateral side of the frame 205d from the second side panel 204 can be seen.
Another function of the first pair of brackets 800 is to secure the second shelf 700 in a vertical position when housed inside the second side panel 204, which can be seen more clearly in FIG. 13.
Similarly, the demountable display module of the present invention comprises second means for supporting the second shelf in a horizontal position when the base is in the “stand up” position, the second means additionally being useful for securing the first shelf in a vertical position when housed inside the first side panel.
In the preferred embodiment that is described, the second supporting means are a second pair of brackets 900 that are attached to the internal surface of the lower side of the frame 205a of the first side panel 201, as can be seen in FIG. 12; the brackets 900 of the second pair include a cylindrically-shaped stem 901 that extends vertically upwardly.
The manner in which the brackets 900 horizontally support the second shelf 700 can be seen in FIG. 11, wherein the second shelf frame 701 can be seen as including a second pair of holes 703 at the internal surface of its free side end to receive stem 901 of each bracket of the second pair. The holes 703 can also be seen in FIG. 13.
Another function of the brackets 900 of the second pair is to secure the first shelf 600 in a vertical position when housed inside the frame 205a of the first side panel 201, as represented in FIG. 12. For such purpose, the first shelf frame 601 includes a third pair of holes 703 over the external surface of its free side end so as to receive the stem 901 of each bracket 900 of the second pair. The third pair of holes 604 can also be seen in FIG. 8.
It shall become evident to those skilled in the art that the first and the second supporting means can be provided in the form of plates coated with Velcro® or with plates including male-female couplings.
On the other hand, at the lower part of FIGS. 12 and 13, it is also observed that the sheet 206a and the sheet 206d of the first and second side panel 201 and 204 extend respectively underneath their frame 205a and 205d to contact the floor, thereby forming a lower lug 215, in which each side panel 201 and 204 includes a reinforcement plate 216 attached to its sheet and to the external surface of the lower side of its frame, so as to withstand the vertical stresses applied over the module when totally mounted.
Another important feature of the preferred embodiment of the present invention that can be seen in FIG. 13 is that the second shelf 700 includes a pair of fasteners 710 in the shape of a comb that are attached on the internal surface of the second shelf frame 701 and sufficiently separated to each other such that the lower section 401 and the upper section 402 of the posts are fastened by their ends between the teeth 711 of one fastener and the other one. The fasteners are made of PVC or aluminum, preferably aluminum.
Once having described the most significant features of the base 200, it is convenient to refer to FIGS. 14 through 17, wherein various views of the cover 300 can be appreciated, the cover has the shape of a rectangular housing with an upper face 301, side faces 302 and 303, a front face 304, a lid 305 with a handle 306 and the cavities 307; additionally, the cover 300 includes lower tabs 308 extending from the side faces 302 and 303, the front face 304 and the lid 305 towards the interior of said cover 300 running in parallel with respect to the upper face 301. The free end of all the lower tabs 308 form a coupling edge 309 with the same contour that the upper part of the base 200 in its “stand up” position, such that the cover 300 perfectly couples over the base 200. In addition, the lower tabs 308 include 45° cuttings 310 by their lateral sides to make a side contact to each other. These cuttings 310 allow the cover 300 to withstand impacts and loads in case of accidents or during the handling and haulage of the display module with all of the pieces inside the cover 300, thereby overcoming the resistance shortfalls of the prior art.
As mentioned above, at the cover 300, the lid 305 hingedly attaches to the upper face 301. In the embodiment described, this attachment takes place by means of a fifth hinge 315 that fixes inwardly and sideways of the adjacent edges between the upper face 301 and the lid 305. It is important to mention that the upper face 301 includes a recess 311 inside which one of the plates of the fifth hinge 315 is housed (see FIG. 15). The latter has the advantage that it prevents scratches to the surface of the base panel sheets from occurring each time the base is taken out and put into since the hinge stays at a lower level than the internal surface of the upper face 301.
By specifically referring to FIG. 17, it is observed that the handle 306 included in the lid 305 is formed by means of a cloth strip 312 whose ends are bound by the interior of the lid 305 (see FIG. 14). The handle 306 includes a plastic reinforcement 313 that surrounds the section of the cloth strip 312 located externally of the lid 305, as shown in FIG. 17.
The cover 300 also includes means for opening and closing the lid 305 that, in the embodiment shown, comprise the following: a pair of mobile pins 320, each one of them is internally located and close to one lateral side of the lid 305, each pin 320 coming in and out through a hole 314 included at each side face 302 and 303 of the cover 300; a pair of levers 321 operably connected to a pin 320 and driven by the outside of the lid 305 in order to move the pin 320 inwardly and outwardly of the hole 314; and a pair of housings 322 embedded over the lid 305, each housing receiving one lever 321 and including opening and closing position indicators of the lid 305, as specifically shown in FIG. 17.
With the purpose that the cover 300 is further resistant to blows and falls when the parts of the module are stored therein, a pair of reinforcements are provided that, in the embodiment shown, are a pair of bent aluminum sheets 330 at an angle of 90° that are fixed at the internal corners between the front face 304 and the side faces 302 and 303 of the cover 300; in particular, the aluminum sheets are represented by a dashed line in FIG. 15, since they are hidden.
With the purpose of solving the issue of the base movement inside the cover, the display module additionally comprises an impact-absorption pad 340 that is attached and housed inside of the front face 304 of the cover 300; and a pair of impact absorption cushions 350 fixed inside of the lid 305 of the cover 300; the pad 340 and said cushions 350, which can be seen in particular in FIG. 15, impede the horizontal and vertical movement of the base in its “collapsed” position when housed inside the cover 300, the pads 340 and the cushions being manufactured in expanded polystyrene or polyurethane.
Referring now to FIG. 18, an exploded view of one of the posts 400 is shown therein. Each post is formed by a lower section 401 and a upper section 402, and each of these sections 401 and 402 include a coupling portion 403 of tubular profile at their lower end, said portion being of a smaller diameter and thereby forming a lug, wherein in order to assemble each post the coupling portion 403 of the upper section 402 is totally housed inside the upper end of the lower section 401 until the upper section 402 contacts with the lower section 401. Preferably, the upper end of the lower section 401 and the lower end of the upper section 402 each include a 45° second diagonal cutting 404 for providing stability to each of the posts assembled.
Reference is now made to FIG. 19, in order to describe the structure of the board 500, which is formed by a sheet 501 and a pair of coupling bases 502, each of the coupling bases 502 including at its lower end a coupling segment 503 of tubular profile housed and attached inside of the lower end, thereby forming a lug, and the board is coupled to the upper end of each post.
Furthermore, it is convenient to refer to FIG. 20, so as to describe the manner in which the display module 100 is demounted and stored in the form of a briefcase. In said figure, the board 500 is shown demounted from each of the posts 400, which in turn are detached from said cover 300 and the latter from the base 200, wherein both the first shelf 600 and the second shelf 700 move from their horizontal position to be housed, respectively, inside the frame 205a and 205d of the first or second side panel 201 or 204 to which they are attached to, as represented with the movement arrows shown in FIG. 20.
Upon completion of such movement, the shelves reach a vertical position as shown in FIGS. 12 and 13. From FIG. 13, it is important to point out that the lower section 401 and the upper section 402 of each post 400 is housed within the teeth 711 of the fasteners 710 included inside the second shelf frame 701.
Once the first shelf 600 and the second shelf have been housed, the board 500 is placed over the first shelf 600 that is already housed inside the frame 205a from the first side panel 201 as shown in FIG. 21, wherein the first shelf frame 601 is shown with a dashed line since it is hidden by the board 500.
Subsequently, the side panels 201 and 204, having the posts and the board housed in their respective shelf, move inwards the base 200 in order to housed in the inner part of the frame 205b and 205c of the first and second front panel 202 and 203 to which the side panels are attached, as in FIG. 22, which is a rear view of the base 200. After the front panels 202 and 203 has the side panels 201 and 204 housed, they rotate inwards the base over the second hinge 212 to be face to face to bring to the “collapsed” position of said base 200, which is inserted through the lid 305 of said cover 300 that works as a container body as shown in FIG. 23, where the first front panel 202 can be seen in the collapsed base 200.
Once the base 200 is inside the cover 300, the lid 305 is closed by pins 320 which are driven by the levers 321 keeping in this way the display module 100 in the form of a briefcase that can be taken by a user from the handle 306 y carry it anywhere, as shown in FIG. 24. In the briefcase, the base does not move due to the pad 340 and the cushions 350 described in FIG. 14.
In order to protect the cover 300 from scratches when the display module is carried around as briefcase, a cloth or canvas cover within which the entire briefcase is inserted may be used. The cover includes an opening to take the handle of the briefcase.
Regarding the manufacturing materials with which the demountable display module 100 of this invention is manufactured, it is preferred to use PVC either for the frame or sheets of the panels of the base, as well as for the panels, the shelves, and the board. It is also preferred to use aluminum for the used hinges.
In an alternate embodiment, plastic or metallic eyelets are provided to coat the walls of the first, second, and third pair of holes 603, 604, and 703 which are provided in the first shelf and in the second shelf 600 and 700. This same feature also can be included in each hole 714, of the cover. The eyelets have the function of preventing damages and cracks in the nearby zones to the aforementioned holes and piercings.
On the other hand, reference is made to FIG. 25 where it is shown a flow chart of a preferred embodiment of the procedure 1000 to elaborate the display module 100 of this invention. It is worth mentioning that in FIG. 25, the major part of the numerical references that have been used for the most important described elements in FIGS. 1 to 24 are still being kept.
Procedure 1000 starts with a first extrusion step 1050, where from the PVC particles 1001, a first tubular profile 1051 is extruded, preferably a cross-section square profile that, in the first cutting step 1100, is cut in a first six-section-group 1101, each of them with a predetermined length. The sections are used in a construction step 1150, where six frames 205a, 205b, 205c, 205d, 601, and 701 are obtained, from which, frames 205a and 205d are the frames for each of the side panels of the base; frames 205b and 205c are the frames for each of the two front panels of the base, frame 601 is the shelf frame, and frame 701 is the second shelf frame.
