Description

PORTABLE EXHIBITOR CASE BACKGROUND OF THE INVENTION The invention relates to a display system that is portable, self-sustaining and can be packaged, unpacked and repacked, transported and easily used for display purposes in sales presentations, conventions, seminars or the like. Conventional display systems typically provide a relatively large display surface formed by several display panels that are supported by a rack or are self-supporting. These display systems are relatively large and the individual components are normally packaged in a tubular carrier for transport and storage. Larger exhibitors can be reconfigured into smaller displays for desktop presentations, but no display is specifically designed to be relatively small or compact in size for easy transportation and subsequent use as a desk or tabletop display. Examples of conventional display systems of the aforementioned type include those set forth in U.S. Patent Nos. 5,439,043 issued August 8, 1995, U.S. Patent No. 5,611,384 issued March 18, 1997 and U.S. Pat. United States No. 5,791,391 issued on August 11, 1998, all in the name of T. Carter. U.S. Patent No. 4,893,711 issued to Gustafson is not directed to a display case or portable display case, but exhibits a case called convertible carrying case and expandable trestle that includes four relatively slideable panels, best shown in Figure 3 in the open position of the carrying case, compared to the closed position of Figure 1 and the partially open position of Figure 2. The carrying case is hinged to open and close between the position shown in Figures 1 and 2, and are used two arms as a carrier beam (Figure 1) and as support pieces (Figure 4). The knockers (Figure 1) hold the two halves of the case or the two panels in closed position. This patent reflects the closest prior art developed during a search of the present invention, but it can be seen that it lacks a novel structure such as that set forth and claimed herein. U.S. Patent No. 4,524,852 issued to Hess, also discloses a changeable sample case, which includes three panels pivoted together, which upon closing define a display case (Figure 1) that can be opened (Figure 3) and It is supported in vertical form for exhibition purposes. U.S. Patent No. 3,297,118 issued to Van Skyhawk et al. is another example of a carrier case and an exhibitor case in which the haza can be basically pushed, pulled or slid between its carrier position (Figures 1 and 2) and an optionally pivoted and locked display position (Figure 6). Other patents found during the search made for this invention and which are considered to be of less interest and / or exhibit an equivalent or redundant structure corresponding to the structure set forth in the patents already mentioned, include the following: Greene United States Patent No 2,549,306 Mayer, Sr. et al. U.S. Patent No. 2,707,538 Volkert U.S. Patent No. 4,833,802 Judd Patent of the United States No. 4,852,498 SUMMARY OF THE INVENTION A novel portable display of the present invention includes a portable display case formed of a plurality of panel members with adjacent panel members pivotally connected to each other. The portable display case preferably includes four panel members, wherein each panel member has substantially parallel edge portions, top and bottom, and substantially parallel edge portions., on opposite sides, where the edge portions of the adjacent panel members are pivotally connected to each other for movement between a closed position, wherein the panel faces of the panel members are in a substantially opposite relationship to each other. face from panel to panel face, in substantially parallel plane and an open display position, wherein the panel members are in a substantially side-by-side and / or aligned relationship. One of the panel members, preferably one of two panel members that are most toward the center, includes a reciprocating carrier beam, which moves between a non-operating, housed, and a carrier position operant, which allows the portable display case to be carried in the way a portfolio or similar is carried. The carrier beam preferably includes a pair of legs and a hand grip therebetween. The pair of legs are mounted for reciprocating sliding movement in an associated panel member and stops prevent the carrier beam from being removed from its associated panel member. The portable display case also includes slots along the upper edges of the two panel members that are more toward the center, which receive the projections or legs of a head, which allows the head to be supported in a vertical position with relation to the panel members who are more towards the center, in the exhibition position. At least one rear face of one of the panel members includes a recess configured to the shape of the head to receive the head during transport. Preferably, the two panel members more towards the center have recesses that correspond, in their shape, to the head, and which are opposite mirror images to each other and in this way collectively define a single recess that fits in the head , when the two panel members that are more towards the center move towards their closed position. With these objectives and others in mind that will emerge below, the nature of the invention will be more clearly understood in connection with the following detailed description, the appended claims and the various views illustrating the accompanying drawings.

DESCRIPTION OF THE PREFERRED MODALITY A novel portable display case constructed in accordance with this invention is fully illustrated in the drawings and is generally designated with the reference number 10 (Figures 1, 3, 4 and 5). The portable display case 10 includes a plurality of panel members and, in a preferred embodiment of the invention, four of these panel members, 11 to 14 are illustrated in a closed transport or carrier position (Figure 1), a partially positioned position. open (Figure 3) and an open or open position (Figures 4 and 5). Each of the panel members 11 to 14 is of a hollow construction formed from synthetic polymer / copolymer plastic material in a conventional manner, which decreases the weight of the entire portable display case 10, while at the same time increasing the rigidity of it. The panel member 11 is on an outermost, outermost or simply external panel member and includes an upper edge or edge portion 21, a lower edge or edge portion 22, essentially parallel to the upper edge portion 21 and side edges parallel, generally opposite or lateral edge portions 23, 24 (Figure 4). The panel member 12 also includes an edge portion or upper edge 31 essentially parallel to an edge portion or bottom edge 32 and side edge portions or substantially parallel and opposite lateral edges, 33 and 34.

The panel member 13 includes an edge portion or upper edge 41, an edge portion or bottom edge 42, essentially parallel to the first and opposite side edge portions 43, 44, generally parallel. The panel member 14 is an outermost, or simply external, outer panel member and includes upper and lower edge or edge portions 51, 52 disposed essentially parallel to each other and edge portions or vertical side edges 53, 54, opposite and essentially parallel. The front surfaces or "display" (not shown) of each of the panel members 11 to 14 are covered by a sheet of aesthetic fabric material or the like in order to define respective display panels 25, 35, 45 and 55 (Figure 4). The adjacent vertical edge portions 24, 33 (Figure 4) of the adjacent panel members 11, 12 are pivotally connected to each other by upper pivoting means 26, intermediate pivoting means 27 and lower pivoting means 28. The substantially identical pivoting means 26, 27, 28 pivotally connect the panels 13, 14 to each other. Y 12, 13. The pivoting means 26, 28 are essentially identical and the identical identical pivoting means pivotally connect to each other the side edge portions 34, 43 of the panel members 12, 13, respectively and the portions of side edge 44, 53 of the panel members 13, 14 at the respective upper and lower edges. The pivoting means 27 are also located between the pivoting means 26, 27 of the panel members 12, 13 and 13, 14. In this form, three essentially vertical pivot axes Pl, P2 and P3 (Figure 4) are provided. and around these the panel members 11 to 14 can selectively pivot between the fully closed transport / carrier position of the portable display case (Figure 1) to and through the partially open / closed position of Figure 3 and the fully open or display position of Figures 4 and 5. It should be noted from Figure 3 that as the panel members 11 to 14 move toward the closed position of Figure 1, the display surfaces or the panels of respective display 25, 35 and 45, 55 move progressively towards each other until they are in an opposite relation from panel to panel face, in substantially parallel planes when the portable display case 10 is completely closed, as will be easily visualized in Figure 1 of the drawings. This same pivotal closing movement leads the rear surfaces (countless) of the two panel members further toward the center 12, 13 towards an opposite panel-to-panel face relationship, also in essentially parallel planes, for a purpose fully described below. As will be better illustrated in Figures 6 to 8 of the drawings, each of the pivot means 26, 27 and 28 includes an integral pin 36 to 38, carried by the side edge portion 33 of the panel member 12 (and the side edge portion 44 of the panel member 13) and the respective pin receiving recesses or channels 46 (Figure 7), 47.a, 47b (Figure 8) and 48, which are carried by the side edge 24 of the panel member 11 (and side edge 33 of panel member 14). The pivot pins 36, 38 have respective ends 56 (FIG. 7), 58 (FIG. 8) projecting respectively downwardly and upwardly and are clamped within the respective pin receiving channels 46, 48 and are retained in the same. The pin 37 (Figure 8) includes opposed projecting ends 57a, 57b (Figure 8) which are received under pressure within respective pin receiving channels 47a, 47b. Due to the identical construction of the pivoting means 26, 27 and 28, the panel members 11, 14 are interchangeable and when exchanged, the upper edge portions 21, 51 become the lower edge portions., while the lower edge portions 22, 52 are converted into the upper edge portions. This exchange capacity of the panel members 11, 14 is highly desirable because a single mold is required to form any of the panel members 11, 14, which are essentially identical in construction, thus reducing overall manufacturing costs. . In order to achieve the exchange capacity of the panel members 11, 14, the symmetry of the members must be maintained when they are "turned" or "turned" essentially at 180 ° from the position illustrated in Figures 4 and 5, with relation to all other cooperating components and for this purpose the side edges 23, 54 of the panel members 11, 14 are provided with centrally located hand holding receiver recesses 61, 62, and with two sets of knockers 63, 64 and 65, 66 of the display case (Figures 3 and 4). The knock components 63, 66 are flexible knockers, each having a rectangular opening 67 and a knob 68, while the components 65, 66 each are generally polygonal knocker projections or knockers flanges sized to be received within the associated opening 67 of the knocker tab 63, 66. As will be evident from Figures 3 and 4 of the drawings, the positions of the knocker tabs 63, 66 and of the knocker projections 64, 65 are reversed with relation to the panel members 11 and 14, thereby facilitating the fabrication of a single end panel member 11 or 14 in a mold, for use as any of the panel members 11, 14. Each of the panel members 12 , 13 includes a respective head-receiving recess 72, 73 (Figure 5), where each has a configuration that corresponds essentially identically but somewhat larger than the configuration of a "head" 80 (FIG. 4 to 6) that is housed in any of the panels 72, 73, or both, in the closed or transported position of the portable display case 10, as will be apparent from Figure 6, or the head 80 is placed in the expanded ratio (Figures 4 and 8) towards the panel members 12, 13 in the display position of the portable display case 10. The head receiving recesses 72, 73 each include a respective relatively straight edge 74, 75 interrupted by edges 76, 77 and 78, 79, which are generally C-shaped or U-shaped respectively. The arcuate edges 91, 92 of the head receiving recesses 12, 13, respectively, are opposite the generally straight edges 74, 75, and each is interrupted by two finger-receiving recesses 93, 94 and 95, 96, respectively (Figure 8). As will be evident from Figure 6, the finger receiving recesses 93 to 96, each accommodate a person's finger in order to facilitate removal of the head 80 from any of the recesses 72, 73, as will be evident from the Figure 6 of the drawings. The latter could be necessary because each of the straight edges 74, 75 and / or the arcuate edges 91, 92 include a pair of identical retaining flanges 101, 102 and 103, 104 (Figures 6 and 8) below which an arched edge 81 and an opposite straight edge 89 of the head 80 is snapped (Figures 6 and 8) for retention in the head receiving recesses 72, 73. The head 80 also includes two projections 82, 83 ( Figures 4 and 6) that sit on the C-shaped or U-shaped recesses or edges, 76, 77 and / or 78, 79. The projections 82, 83 are inserted into slots that open upwards 112, 113 (Figures 4 to 6) through the upper edges 31, 41 of the respective panel members 12, 13. As will be evident from Figure 4 of the drawings, the head 80 has a length essentially corresponding to the distance between the pivot axes Pl, P3 and in this way corresponds in length to twice the distance between the edges 33 , 34 and / or 43, 44. Therefore, the overall vertical distance between the edges 31, 32 and / or 41, 42 is slightly greater than the length of the head 80, to allow the formation of the head receiving recesses 72, 73 within the overall vertical height of the central panel members 12, 13. In other words, the overall length of the head 80 essentially corresponds to the overall length of the head receiving recesses 72, 73 (according to its vertical measurement in Figure 5) that a its time is essentially the same as the vertical heights of the panels 12, 13, once again measured between the edges 31, 32 and 41, 42, respectively, while these latter lengths correspond to approximately twice the width of any of the central panels 12, 13, again measured between the edges 33, 34 and / or 43, 44. Adjacent to each of the finger receiving recesses 93 to 96 are identical center panel knockers 123 to 126. As shown in FIG. better illustrated in Figure 7, the central panel knocker means 123 includes a raised projection 127 and an upwardly directed ledge 128. The corresponding doorknob means 125 includes a similar projection (without number) and the knocker flange corresponding to the ledge 128 projects downwards, as it is shown in Figure 5. Similarly, the flange (without number) of the latch means 124, 126 projects respectively downwards and upwards. Accordingly, when the panel members 12, 13 are pivoted to the closed position (Figure 1), the knocker flanges 128 of the latch means 123, 125 and 124, 126 are pressurized together due to the inherent resilience of the material and can easily be separated to pivot from closed position to the open position (Figure 5). A means in the form of a retractable carrying handle 130 (Figures 1 and 9) is provided for carrying the portable display case 10 when in the closed position thereof (Figure 1). The retractable carrying handle 130 includes a hand grip or holding handle 131 and a pair of generally parallel legs 132 having respective projections 134, 135 that function to prevent the handle 130 from being fully withdrawn from the associated central panel 112 or 113. More specifically, as the central panels 12, 13 are similarly symmetrical or are constructed identically to each other, each includes perforations or recess means 144, 145 (Figure 9) into which the legs 132, 133. slide. 144, 145 includes a respective shoulder or shoulder of the respective stop 146, 147 (Figure 9) against which the projections or protrusions 134, 135 encounter when the carrier handle 130 is in its fully extended position, thus preventing further outward movement of the legs. same. A plate 150 is conventionally secured in overlapping relationship to the perforations 144, 145 of the two panel members 12, 13 (Figure 5). The hand grip 131 is, of course, contoured to engage the contours of the handle receiving recesses 61, 62 to fit fully therein to the hand holding portion 131 both in the closed non-carrying or use position. of the portable display case, as illustrated in Figure 2, as in the display position (Figure 5). As noted in the foregoing, the panel members 11, 14 are symmetrical to allow their exchange and this also happens for the panel members 12, 13, which allows these identical panel members to be molded in a single mold, reducing thus the overall costs of the portable display case 10. In order to achieve this interchangeable characteristic, the head / recess 72, 73 (Figure 5) are not only identical, but are mirror images of one another and can be interchanged with each other, and if this is done with respect to the display case of Figures 4 and 5, it would be placed at the lower edges 32, 42 of the respective panel members 12, 13 that are further upwards and the identical pivot means 26, 27 and 28 would pressurize the side edges 33, 34 of the respective panel members 12, 13 with the side edges 24, 55 of the respective panel members 11, 14. The "bottom" edges 32, 42 of the members of respective panels 12, 13 have recesses 112, 113 (FIG. 5) corresponding to the recesses having identical number and are adjacent to the upper edges 31, 41, and this allows the head 80 to be inserted in the manner shown in FIG. Figure 5 after the panel members toward the center 12, 13 have been turned over or "turned" in the manner just described. Accordingly, the overall manufacturing cost of the portable display case 10 is appreciably reduced because a single mold is required to mold the panel members 12, 13 there and a single mold is not used to mold the panels. same to panel members 11, 14. Although a preferred embodiment of the invention has been specifically described and illustrated here, it should be understood that minor variations may be made in the apparatus without departing from the spirit and scope of the invention, as defined in appended claims.
