DETAILED DESCRIPTION OF THE SEVERAL EMBODIMENTS OF THE
INVENTION
-Referring to Eigures 1, 2, and 3 showing the first embodiment, the sign board, generally indicated at 1, defines a flat body, made of the following laminations:
a continuous backing 2; a spacer lamination 3; and a facing sheet lamination 4. The spacer lamination 3 is adhered to the backing 2 and the facing sheet lamination 4 is in turn adhered to the spacer lamination 3. The resulting body may have a generally rectangular shape, with rounded corners 5. The backing sheet 2 and facing sheet 4 may be made of the same sheet material, such as a synthetic resin or carton. The spacer lamination 3 is preferably made of a foamed, lightweight plastic and has a greater thickness than that of the backing 2 and facing sheet 4.
The spacer lamination 3 defines a plurality of pockets 6, each having on one side an access opening 7.
These pockets 6 are formed by cutouts made in the spacer lamination 3. Each pocket 6 is designed to hold a stack of individual display sheets 8, each display sheet of the stack being removable from the pockets 6 through its access openin~ 7~, and the display sheets can be interchanged in their order within the pockets 6. The facing sheet 4 is cut out to form windows g, each registering with a pocket 6 and of a smaller size than the same, so that the marginal portion of the windows 9 will overlie the ~Z234~L
frontmost display sheet 8 of the stack and retain the stack within the pocket. The frontmost display sheet only is visible through -the window 9, while the other display sheets of the stack are hidden from view by the frontmost display sheet of the stack. In each stack, there are as many display sheets 8 as there are variables in the message to be displayed in the particular pocket. For instance, in the embodlment shown wherein the permanent display 10 imprinted on the facing sheet 4 at one end thereof and which relates to video cassettes, the price of s~ch cassettes is indicated by the combination of the display sheets 8 in the four pockets shown. Thus, each stack ~fdisplay sheets will display a number from 0 to 9, whereby the price display can be varied from 0 to $99.99.
Ther~fore,in each pocket 6, there are disposed a stack of ten different display sheets 8, as shown in Figure 1. In this embodiment, the backing sheet 2 protrudes upwardly from the access openings 7 to form an extension 11 and a locking strip 12 is removably adhered by adhering means to the extension 11, said locking strip being co-extensive with the extension 11. The adhering means may simply consist of removably-interengageable adhering complement-ary strips 13 and 14, for instan~e of the type known under the registered trade mark VELCR0, each strip 13 and 14 permanently adhered to the backing extension 11 and to the locking strip 12, respectively. The locking strip 12, once in position, extends across the different access openings 7 permanently locking the display sheets 8 within the respective pockets, so that the display sheets 8 will not accidentally spill during manipulation of the board 1.
Board 1 can be suspended from a ceiling, attached to a stand or to a wall. The board 1 can be made of double A
44:1 construction, with the same backing 2 provided on each of its main faces Witil the spacer lamination 3 and facing sheet 4, so as to provide an advertising or display message visible on both sides.
Figures 4 to 7 show a second embodiment, which is of the same construction as the first embodiment, the flat body also formed of three laminations, namely: the backing 2', the spacer lamination 3', the facing sheet 4', and the locking strip 12'; all of the pockets 6' have an access opening 7' disposed at the top side of the main facing sheet 4i; but there is an additional pocket 15 with its access opening 16 disposed at one side of the body for receiving an additional stack of display sheets 17, of similar size, each interchangeable and removable from the side of the board. The locking strip 12' is thus formed of three laminations: namely, a backing sheet 18, a spacer sheet 19, and a facing sheet 20. The spacer sheet 19 forms a pocket 21 with a lateral a~cess opening 22 and the facing sheet 20 defines a window 23, of smaller size than the pocket 21 for retaining a stack of several display sheets 24 removable laterally of the board 1 through the access opening 22. The locking strip 12'is removably adhered to the backing extension 11' by means of Velcro strips 13' and 14', respectively. Furthermore, the second embodiment is characterized by the fact that the body thereof has a further extension 25, also of laminated construction, and extending above the locking strip 12'. When the locking strip 12' is in adhered position, the facing sheet of the whole assembly is at the same level, except for the windows.
The third embodiment is illustrated in Figures 8 to 10. In this embodiment, there is no locking strip equivalent to locking strip 12 or 12'. The board is made ~L~Z3441 of two sections havlng a common backing 2'' to which are adhered two separate spacer laminations 3'', a -top and a bottom one~ each spacer lamination is spaced from each other to form a (Jroove 26 at about midway of the backing 2''. Each spacer lamination 3'' is formed with a plurality of pockets 6'', each having an access opening 7ll, the access openings 7'' all o~ening at the top edge of the spacer lamination 3''. There i5 an additional pocket 15'' in each spacer lamination sheet 3'' having an access opening 16'' opening laterally of the board. Each pocket 6'' receives a stack of display sheets 8'' and, similarly, the additional pockets 15'' receive a stack of display sheets 17''. The stack of each sheet is completely interchangeable and only the frontmost sheet of the stack will be displayed through the associated window of the pocket.
In all of the embodiments, whenever it is desired to change the display sheet ln any pocket, it is only necessary to slide the foremost display sheet by finger pressure out through the access opening and, similarly, for the successive display sheets till the right display sheet is displayed. The removed display sheets arP
re-inserted back into the same pocket at the back of the stack. This is also possible for the bottom section of the embodiment of Figure 8, since these display sheets are somewhat flexible. As shown, the pockets may have different sizes and shapes and, normally, each embodiment has a permanent display, indicated at 10, 10' or 10''.

DETAILED DESCRIPTION OF THE SEVERAL EMBODIMENTS OF THE
INVENTION
-Referring to Eigures 1, 2, and 3 showing the first embodiment, the sign board, generally indicated at 1, defines a flat body, made of the following laminations:
a continuous backing 2; a spacer lamination 3; and a facing sheet lamination 4. The spacer lamination 3 is adhered to the backing 2 and the facing sheet lamination 4 is in turn adhered to the spacer lamination 3. The resulting body may have a generally rectangular shape, with rounded corners 5. The backing sheet 2 and facing sheet 4 may be made of the same sheet material, such as a synthetic resin or carton. The spacer lamination 3 is preferably made of a foamed, lightweight plastic and has a greater thickness than that of the backing 2 and facing sheet 4.
The spacer lamination 3 defines a plurality of pockets 6, each having on one side an access opening 7.
These pockets 6 are formed by cutouts made in the spacer lamination 3. Each pocket 6 is designed to hold a stack of individual display sheets 8, each display sheet of the stack being removable from the pockets 6 through its access openin~ 7~, and the display sheets can be interchanged in their order within the pockets 6. The facing sheet 4 is cut out to form windows g, each registering with a pocket 6 and of a smaller size than the same, so that the marginal portion of the windows 9 will overlie the ~Z234~L
frontmost display sheet 8 of the stack and retain the stack within the pocket. The frontmost display sheet only is visible through -the window 9, while the other display sheets of the stack are hidden from view by the frontmost display sheet of the stack. In each stack, there are as many display sheets 8 as there are variables in the message to be displayed in the particular pocket. For instance, in the embodlment shown wherein the permanent display 10 imprinted on the facing sheet 4 at one end thereof and which relates to video cassettes, the price of s~ch cassettes is indicated by the combination of the display sheets 8 in the four pockets shown. Thus, each stack ~fdisplay sheets will display a number from 0 to 9, whereby the price display can be varied from 0 to $99.99.
Ther~fore,in each pocket 6, there are disposed a stack of ten different display sheets 8, as shown in Figure 1. In this embodiment, the backing sheet 2 protrudes upwardly from the access openings 7 to form an extension 11 and a locking strip 12 is removably adhered by adhering means to the extension 11, said locking strip being co-extensive with the extension 11. The adhering means may simply consist of removably-interengageable adhering complement-ary strips 13 and 14, for instan~e of the type known under the registered trade mark VELCR0, each strip 13 and 14 permanently adhered to the backing extension 11 and to the locking strip 12, respectively. The locking strip 12, once in position, extends across the different access openings 7 permanently locking the display sheets 8 within the respective pockets, so that the display sheets 8 will not accidentally spill during manipulation of the board 1.
Board 1 can be suspended from a ceiling, attached to a stand or to a wall. The board 1 can be made of double A
44:1 construction, with the same backing 2 provided on each of its main faces Witil the spacer lamination 3 and facing sheet 4, so as to provide an advertising or display message visible on both sides.
Figures 4 to 7 show a second embodiment, which is of the same construction as the first embodiment, the flat body also formed of three laminations, namely: the backing 2', the spacer lamination 3', the facing sheet 4', and the locking strip 12'; all of the pockets 6' have an access opening 7' disposed at the top side of the main facing sheet 4i; but there is an additional pocket 15 with its access opening 16 disposed at one side of the body for receiving an additional stack of display sheets 17, of similar size, each interchangeable and removable from the side of the board. The locking strip 12' is thus formed of three laminations: namely, a backing sheet 18, a spacer sheet 19, and a facing sheet 20. The spacer sheet 19 forms a pocket 21 with a lateral a~cess opening 22 and the facing sheet 20 defines a window 23, of smaller size than the pocket 21 for retaining a stack of several display sheets 24 removable laterally of the board 1 through the access opening 22. The locking strip 12'is removably adhered to the backing extension 11' by means of Velcro strips 13' and 14', respectively. Furthermore, the second embodiment is characterized by the fact that the body thereof has a further extension 25, also of laminated construction, and extending above the locking strip 12'. When the locking strip 12' is in adhered position, the facing sheet of the whole assembly is at the same level, except for the windows.
The third embodiment is illustrated in Figures 8 to 10. In this embodiment, there is no locking strip equivalent to locking strip 12 or 12'. The board is made ~L~Z3441 of two sections havlng a common backing 2'' to which are adhered two separate spacer laminations 3'', a -top and a bottom one~ each spacer lamination is spaced from each other to form a (Jroove 26 at about midway of the backing 2''. Each spacer lamination 3'' is formed with a plurality of pockets 6'', each having an access opening 7ll, the access openings 7'' all o~ening at the top edge of the spacer lamination 3''. There i5 an additional pocket 15'' in each spacer lamination sheet 3'' having an access opening 16'' opening laterally of the board. Each pocket 6'' receives a stack of display sheets 8'' and, similarly, the additional pockets 15'' receive a stack of display sheets 17''. The stack of each sheet is completely interchangeable and only the frontmost sheet of the stack will be displayed through the associated window of the pocket.
In all of the embodiments, whenever it is desired to change the display sheet ln any pocket, it is only necessary to slide the foremost display sheet by finger pressure out through the access opening and, similarly, for the successive display sheets till the right display sheet is displayed. The removed display sheets arP
re-inserted back into the same pocket at the back of the stack. This is also possible for the bottom section of the embodiment of Figure 8, since these display sheets are somewhat flexible. As shown, the pockets may have different sizes and shapes and, normally, each embodiment has a permanent display, indicated at 10, 10' or 10''.
