BRIEF SUMMARY OF THE INVENTION The invention provides a frame assembly for carrying display panels for advertising and other purposes which includes a pair of generally polygonal allochiral frames having means for carrying a display panel between them, an internal groove with an opening therein on the inner side of each of said frames and a connecting member having an intermediate portion and opposing ends shaped to fit said internal grooves and inserted in said grooves of two adjacent opposing members with said intermediate portion extending through said openings to connect the said frames so as to permit pivoting of said frames around said connecting member to open and closed positions while retaining said frames in a predetermined relationship with one another and in contact with one another adjacent said connecting member when in said open position. The construction is preferably such that the pivotal movement of said frames is limited to a generally V-shaped open position. An improved type of snap lock clip is also provided to hold the frames together in the closed position and, if desired, to provide a means for hanging the frame assembly. Due to the structure of the individual frame members one of them can be used with a special clip to hold a display panel against a wall or other surface.

DETAILED DESCRIPTION OF THE INVENTION As shown in FIG. 1 the frame assembly of the invention comprises a pair of rectangular allochiral frames 1 and 2. Frame 1 has opposing

side members

3 and 4, a lower member 5 and an upper member 6. Frame 2 has opposing

side members

7 and 8, a lower member 9 and an upper member 10. Each of the frame members 1 and 2 is constructed similarly in that they are mitered at the corners and are held together at each of the corners by an L-shaped corner member 11 as shown in FIGS. 6 and 7.

Each of the

frame members

3, 4, 5 and 6 in

frame

1 and 7, 8, 9 and 10 in frame 2 is constructed with a channel or recess 12 therein which extends throughout the length of each of said members and is adapted to receive the L-shaped connecting members 11 at the corners. The recesses 12 are undercut at 13 and 14 so that the inwardly projecting

frame portions

15 and 16 on either side of the opening 17 are in contact with connecting members 11. Connecting members 11 contain an L-shaped embossment 18 to increase rigidity and a plurality of embossments 19 to further increase rigidity and to contact the inner sides of channel 12 so that the corners of the frames will not wobble and will remain tightly fixed. To facilitate rigidity, the internal groove 12 in each frame member preferably has a width at least half as great as the width of the frame member. Thus, in a frame member of the type shown in the drawings having a width of approximately 1 inch, the width of channel 12 would be at least one-half inch. The overall thickness of each of the

frame members

3, 4, 5, 6 and 7, 8, 9, 10 having a width of approximately 1 inch, might be, for example three-eighths inch.

Each of these

frame members

3, 4, 5, 6 and 7, 8, 9, 10 also contains a groove 20 running lengthwise on the interior surface having an opening 21 as shown in FIG. 4. All of said frame members also contain an inwardly extending flange 22.

A connecting member 23 having an intermediate portion 24 and opposing

ends

25 and 26 shaped to fit said

internal grooves

20,20 is inserted in said grooves with said intermediate portion extending through said openings 21,21 to connect said lower members and 9 so as to permit pivoting of said frames 1 and 2 around said connecting member to open and closed positions while retaining them in a predetermined relationship with one another and in contact with one another at the lower sides 27 when in the open position shown in FIGS. 1 and 4. 1 The angle between the frames 1 and 2 in the open position can be varied (usually within the range of to 60) but should be large enough to permit the insertion of a display panel 28 so that when the frames 1 and 2 are closed the display panel will rest on the

flanged portions

22,22 and, if it is a three-dimensional panel, will project beyond one of the frames as shown in FIG. 2. If two display panels are placed back-to-back between the frames 1 and 2 while in the open position so that they rest on the

flanged areas

22,22 and the frames are then closed, the result will be a frame assembly as shown in FIG. 3, and if both panels are threedimensional, the

portions

29 and 30 will project beyond the sides of the frames.

One of the features of the invention is the provision of a base as illustrated in FIG. 10 containing a base plate 31 on which is mounted a vertical rod 32 and a channel member 33 comprising an intermediate channel portion 34 containing a recess 35 in which the

lower members

5 and 9 of the frame assembly are received and two

vertical channel members

36 and 37 containing

recesses

38 and 39 in which

side members

3,8 and 4,7 of the frame assembly are received. In this manner the frame assembly is held in closed position without locking or otherwise fastening the frames 1 and 2 together.

Where it is desired to provide independent means for fastening the frames 1 and 2 together after the display panels have been inserted, one of the features of the invention is the provision of a snap lock clip 40 as illustrated in FIG. 9 which is in the form of an inverted T wherein the

opposing ends

41 and 42 of the horizontal portion have a generally circular cross section adapted to be received by

grooves

20,20 which also have

side openings

43 and 44 and are made of a resilient plastic or other suitable material molded in one piece with the vertical portion 45. The clip 40 can be snapped into the

grooves

20,20 due to the resilience of the

end portions

41,42. Likewise, by applying pressure, the frame members 1 and 2 can be pulled apart and clip 40 removed.

If it is desired to suspend or hang the frame this can be done by providing an opening 46 in clip 40 through which one end of an S hook 47 can be inserted and the other end attached to a supporting member 48 which in turn is attached to a ceiling, a beam or any other type of fixed structure.

From the foregoing description it will be seen that a frame assembly of the type described is advantageous for carrying display panels, particularly advertising and other promotional material, including threedimensional display panels, so that the same or different display panels can be viewed from opposite sides of the frame assembly and the structure of the frame assembly and the method of inserting and removing the display panels is relatively simple. The structure of the frame members and the bottom connecting member makes it possible to limit the pivotal movement to a partially open position in which the display panels can be inserted or withdrawn from the frames. The frame members can be made of extruded aluminum or any other suitable material which is relatively rigid. The connecting member 23 can also be made of extruded aluminum or another suitable material, preferably one which is rigid. The connecting member 23 is normally mounted in the

lower frame members

5 and 9 before these frame members are assembled with the

side frame members

3,4 and 7,8, respectively, by inserting the corner members 11. The corner members 11 are preferably made of metal, or other rigid material. If desired, they can be cemented into place with adhesive applied at 49 and 50 or elsewhere. The

embossments

13 and 49 can be omitted and other types of corner members 11 can be used. Hence, once the frames 1 and 2 have been assembled with the rigid corner members 11 a very permanent type of structure is formed which is quite rugged and capable of withstanding hard usage to which it might be subjected when it is employed in advertising and promotional displays, particularly when such displays are changed from time to time. In addition, the invention provides a new and improved means for mounting and/or hanging the frame assembly and a new and improved means for locking the frames together with a new and improved snap lock clip.

Due to the special structure of each individual frame member 1 or 2 it is possible to use a single frame member with a special clip to hold a display panel against a wall or other surface. This feature of the invention is illustrated in FIG. 5 which shows the upper part of frame member 1 which is adapted to be associated with a special clip 51, illustrated in FIG. 5A. The special clip 51 has an elongated portion 61 which is adapted to provide a retaining wall on one side for display panel 52 and on the other side is adapted to be fastened to a wall 53 or other suitable surface by means of adhesive 54, or other suitable means. Flange 55 of frame member 1 serves to restrain the upward movement of display panel 52. The inward movement of display panel 52 is prevented by the portion 56 as well as the inner side of lower part 6 of frame member 1. The recess 57 in the modification shown in FIG. 5 corresponds to the recess 12 in the embodiment shown in FIG. 8. The groove 58 corresponds to groove 20 in FIG. 8. The under portion 59 of clip 51 corresponds to one of the under

portions

42 or 43 in clip 40 shown in FIG. 9. The under portion 59 has a slit along one side thereof providing the opening 60. It will be noted that the portion 62 of clip 51 is at an angle to the portion 61 so that the inner side of the portion 62 will rest against the upper inner side of frame member 1 when the clip is inserted with the under portion 59 in groove 58. The clip 51 is preferably made of material such that the sides of under portion 59 are flexible or resilient enough so that the under portion 59 can be snapped into groove 58. When it is desired to remove frame member 1 from clip 51 this can be done merely by pulling outwardly so as to cause the sides of the flexible under portion 59 to yield toward one another and pass through the opening on the inner side of grooves 58.

It will be apparent that the invention is susceptible to a number of modifications and variations in the manner in which the frame members are used. As an example the snap lock clip 40 is illustrated in FIG. 8 as it is used for the purpose of suspending the frame assembly with the snap lock clip 40 in the form of an inverted T. However, when it is desired merely to lock the frame members together, the snap lock clip 40 can be used in an upright position, i.e., with the vertical portion 45 extending downwardly between the frame members. When used in this manner the means for holding the frame members together is not readily apparent to the casual observer. When the snap lock clip is used in this manner and it is desired to separate the frame members after they have been locked together a screw driver or similar tool can be used to pry them apart causing the under

portions

42 and 44 of clip 49 to be removed from the

grooves

20,20. It should also be understood that the snap lock members can be employed on the sides of the frames as well as at the top and that the frame assembly can be used with the

sides

4,7 and 3,8 forming either the top or bottom of the assembly and the pivoted

sides

5,9 being to one side of the assembly.
