DETAILED DESCRIPTION

Referring now to the drawings, there is shown, in FIG. 1 a portable display system in accordance with the present invention. FIGS. 2-4 show further details of construction particularly with regard to the border strip means that is employed in the invention. The display system comprises a plurality of panel assemblies separated into an upper array 10 and a lower array 12. Each of these arrays comprises four separate panel assemblies. The upper array 10 includes a main panel assembly 14, and three other connected panel assemblies 15. Similarly, the lower array includes a main panel assembly 16 and three other interconnected panel assemblies 17. Each of the panel assemblies comprises a rectangular frame 18 also referred to herein as a border strip device, and a pair of parallel confronting panels or wallboards 20 and 21.

The main panel assembly 14 has the next adjacent section 15 hinged thereto by means of a suitable double hinge 25. Other similar hinges are employed to hinge the remaining panel assemblies 15 adjacent to each other. Further details of the double hinge are depicted in FIGS. 2 and 4. Similarly, the main panel assembly 16 of array 12 has the next adjacent section 17 hinged thereto by means of the same type of double hinge 25. Also, the remaining sections 17 are hinged in succession by means of such a double hinge 25. This double hinge arrangement permits essentially two-way hinging as depicted in the middle two assemblies of each array 10 and 12 of FIG. 1. Two hinges are employed between each panel assembly although in an alternate embodiment more than two hinges could be employed.

In addition to the double hinges 25 that are used between panel assemblies in each array, there are also provided two corner hinges 26. These corner hinges 26 are disposed on opposite sides of the main panel assemblies 14, 16. Thus, one of the hinges 26 connects between border strips 18A of panel assemblies 14 and 16 while the other corner hinge 26 extends between border strips 18B of main panel assemblies 14 and 16. FIG. 2 shows also the corner hinge 26 on one side of the main panel assemblies.

With the arrangement depicted in FIG. 1, the entire upper array 10 can be pivoted relative to the lower array 12 by means of the two corner hinges 26. The remaining panel assemblies are not hinged between arrays, but instead are interlocked into position by means of an interlocking or registration technique described hereinafter.

FIGS. 2 and 4 show the double hinges 25 which include outer hinge plates 25A and 25B and intermediate hinge plate 25C. This hinge may be of the type described in my previous U.S. Pat. No. 4,147,198. As depicted in the drawing, the hinge is attached by bolts or screws 28 which pass through the hinge and into the border strip means 18. Similarly, the corner hinge 26 may be of the type described in my U.S. Pat. No. 4,147,198 with screws or bolts 30 being provided for securing the corner hinge to the respective border strip means.

As depicted in the drawings, there are basically two different border strip arrangements depicted respectively in FIGS. 3 and 4. The first of these peripheral support means is shown in FIG. 3 comprising a fixed member 34 that is preferably hollow, as shown, and a removable member 36 that is adapted to snap fit with the fixed member 34. The members 34 and 36 are adapted to be interconnected in only one of two possible positions by means of a keying arrangement including a slot 35 at one corner of the fixed member cooperating with a shoulder 37 of the removable member 36. Each of the removable members also includes a tongue and groove arrangement including tongue 39 and groove 40. The keying arrangement including the slot 35 and the shoulder 37 prevents misalignment between the tongue and groove arrangement of one member 36 which is adapted to interlock with an adjacent member 36. FIG. 3 shows the correct position. However, if one of the members 36 was snap-fitted in an opposite direction, then the tongues and grooves would not line up but instead a tongue would line up with a tongue and a groove with a groove which is not desired.

When the removable outer member 36 is disengaged from the fixed member 34 the overall panel assembly stays intact. This may be accomplished in the same manner as in the construction of my prior art patent such as by the use of a corner locking device inserted within the hollow of member 34.

The tongue and groove interlock arrangement extends along each removable member a distance less than the length of the removable member as illustrated in FIGS. 1 and 2 leaving interlock free ends that enable corresponding ones of the panel assemblies of the adjacent arrays to be maintained folded as illustrated in FIG. 1, out of interlock relationship, while the main panel assemblies 14 and 16 are interlocked as also illustrated in FIG. 1. The interlock means extend at least in part out of the outer surface of the removable member such as illustrated in FIGS. 2 and 3.

Between the member 34 and walls 42 of the member 36 there is defined a channel for receiving the panels 20, 21. However, when the member 36 is disengaged from the fixed member 34, then the panels 20 and 21 are free to be withdrawn from the display system. In the disclosed embodiment of FIG. 1, this first type of border strip, including a removable section is provided only at the interface between the upper and lower arrays. Thus, the tongue and groove interlocking arrangement occurs between each of the panel assemblies 15 and 17 and also between the panel assemblies 14 and 16. The remaining border strip means may all be of the type depicted in FIG. 4 wherein the entire border strip is of the fixed type particularly, where the hinges 25 are fastened. A border strip device as depicted in FIG. 4 is used.

In FIG. 4 the border strip device includes an inner member 46 integral with an outer section 48. The inner member 46 is similar to member 34 in that it is hollow and forms the means by which different linear sections of the border strip are interconnected by means of a corner locking device not shown in the drawings. This locking device as previously mentioned may be of the type shown in my previous U.S. Pat. No. 4,147,198. The outer section 48 includes walls 49 defining with the inner member 46 oppositely disposed channels for the panels 20 and 21. The border strip device shown in FIG. 4 may be employed in the embodiment of FIG. 1 on all vertical portions of the frames of the panel assemblies. Also, this form of a border strip device may be used at the bottom of the frame in array 12 and at the top of the frame in array 10.
