Description:

This invention appertains to a medium for expressing thought or intellectual conceptions, and more especially, to instrumentalities for conveniently displaying printed text matter and/or pictures in a continuous sequence.

Still more specifically, it is the primary object of the present invention to provide a new medium by which stories and/or pictures may be displayed or communicated to children, and which has a somewhat stronger appeal and attractiveness to children than a book of conventional form.

My invention may be characterized as a book, yet it is endowed with a number of novel features which are not found in an ordinary book. To this end, the invention contemplates the provision of an outer casing of sheet material, such as cardboard, folded into box-like form of the approximate size of a conventional story book, said casing being preferably decorated or otherwise marked to simulate a conventional book. Remov0ably mounted within the casing is a frame, also composed of sheet material such as cardboard, which constitutes a support for a pair of spaced rolls upon which a flexible strip or sheet is wound, said sheet having text matter and/or pictures 25 printed or otherwise carried thereby, so as to be presented to view in a continuous sequence through an opening formed in one face of the outer casing when the rolls are manipulated to 0 wind the strip or sheet from one roll onto the other roll.

Other and further objects and advantages of the invention will be hereinafter described, and the novel features thereof defined in the appended claims.

In the drawings: Figure 1 is a perspective view of a preferred embodiment of my invention; Figure 2 is a longitudinal sectional view, taken 0 aproximately on the line 2-2 of Figure 1; Figures 3 and 4 are transverse sectional views, taken respectively on the lines 3-3 and 4-4 of Figure 1; Figure 5 is a detail view in top plan of the insertible frame and roll assembly which is preferably of unitary form; Figure 6 is a plan view of the frame as it is initially formed from a flat sheet of material and prior to folding thereof, and particularly showing its preferred one-piece construction; and Figure 7 is a plan view of the outer casing as it is initially preferably formed from a flat sheet and prior to folding thereof, and illustrating its preferred one-piece construction.

Ar Like reference characters designate corresponding parts in the several figures of the drawings, wherein I generally designates an outer casing or housing which is preferably composed of sheet material such as cardboard, folded into box-like form. As best seen in Figure 7, the casing is preferably of one-piece construction and includes a front wall section 2 having an opening 3 of substantial size provided therein; an end wall 4 constituting a continuation of the front wall 2; a rear wall 5 and another end wall 6, each being continuations of the other. The front wall 3 is provided with an extension 7 which serves as an attachment flap to secure the walls together into box-like form when folded along the transverse fold lines 8, 9, 10 and I , respectively. The flap 7 may be provided with a suitable adhesive so as to enable the same to be attached to the end wall G, as will be best understood from reference to Figure 2. The end walls 4 and 6 are each preferably provided with lateral tabs 12, 12 and 13, 13, respectively, which are adapted to be folded inwardly on the lines 14, 14 and 15, 15 respectively, so as to aid in closing and to reinforce the corners of the casing.

At one side of the front wall 2 there is provided an integral extension 16 which is adapted to be folded on the line 17 to constitute one of the side walls of the casing, the extension being provided with a tuck flap 18 which is adapted to be folded on the line 19 so as to enable the same to be tucked into the casing in surface engagement with the rear wall 5, as will be best understood from reference to Figures 3 and 4.

Laterally extending from the opposite side of the rear wall 5, is another extension 20 adapted to be folded on the line 2 to constitute the other side wall of the casing, and this extension 20 is provided with a tuck flap 22 adapted to be folded on the line 23 to permit the same to be tucked into the casing in surface engagement with the front wall 2. The extension 20 which forms one of the side walls of the casing is provided with spaced apertures 24, 25 for a purpose which will hereinafter more fully appear. The tuck flaps 18 and 22 may or may not be provided with an adhesive to permit the same to be permanently secured to their respective contiguous casing walls if this is desired upon completion of the entire assembly.

The walls of the casing may be suitably decorated, if desired, to simulate the covers of a conventional book, and the front wall may carry a title of a story, as indicated at 26 in Figure 1, and/or such other informative matter as may be pertinent and/or conducive to the identification of the matter which is to be contained in the casing. Thus it will be seen from reference to Figure 1 that when the casing has been folded and assembled into its box-like form, it will closely simulate the appearance of the exterior of a conventional story book.

Removably mounted in the casing i, is a frame, generally designated 27, the frame being preferably composed of cardboard or similar sheet material which may be cut or stamped in a flat one-piece form as shown in Figure 6. The frame primarily is composed of spaced relatively narrow strips 28 and 29 interconnected by a web 30 of substantial surface area which partially closes one side of the frame when folded into the form shown in Figure 5. The strip 29 is adapted to be folded on the line 31 so as to lie at substantially a right angle to the interconnecting web 30, and the strip is provided at its opposite extremities with extensions 32, 33 which are adapted to be folded on the respective lines 34, 35 to assume positions at right angles to the strip 29.

Similarly, the strip 28 is foldable on the line 36, so as to assume a position at a right angle to the web 30 and parallel to the strip 29, and the strip 28 is also provided with extensions 37, 38 at its opposite ends, which are foldable on the respective lines 39, 40 so as to overlap with the extensions 32 and 33, as will be best understood from reference to Figure 5, the overlapping portions being suitably affixed together.

The strip 28 is provided with spaced apertures 41, 42, and when the frame 27 is folded into the form shown in Figure 5, and is inserted into the casing i, the apertures 41, 42 will register with the respective apertures 24, 25 in the side wall 20 of the casing. The strips 28, 29 and their extensions constitute the walls of the frame which is generally rectangular, and the walls will lie substantially parallel to the end and side walls of the casing I and closely adjacent to the inner sides thereof when the frame is inserted into the casing.

Suitably attached to the strip 29, is a pair of spaced studs or bosses 43, 44 which are adapted to project inwardly from the strip 29 opposite to the respective apertures 41, 42 in the strip 28. The studs or bosses 43, 44 may be formed of any suitable material, such as metal, wood, fiber, or the like, and their attachment to the strip 29 may be effected in any convenient manner. In the case of wood studs, they may be glued or tacked to the frame. Each of the studs or bosses 43 and 44 is adapted to be loosely received in one end of a cylindrical tube or hollow roll, which are respectively designated 45 and 46, and upon these rolls there is wound a strip or web of material 47 having text and/or picture matter printed or otherwise provided thereon. The strip or web 47 may be composed of paper, cloth, parchment, or any other suitable flexible material, which is adapted to be wound upon the rolls 45, 46 so that by rotation of the rolls, the strip will be unwound from one roll and wound upon the other. For the purpose of supporting the ends of the rolls 45 and 46 opposite to their ends which are rotatably mounted on the lugs or studs 43 and 44, I provide spindles 48 and 49 which are adapted to be received through the respective openings 41 and 42 and into the adjacent ends of the rolls 45 and 56.

The apertures 41 and 42 are of such size as to closely embrace the spindles 408 and 49, but enable the spindles to be rotated therein. The inner extremities of the spindles are adapted to fit tightly in the ends of the rolls so that rotation of the spindles will impart rotation to the rolls. If desired, the spindles may be adhesively or otherwise positively affixed to the rolls. The outer extremity of each of the spindles is provided with a knob 50, 51 for convenience of rotation of the spindles. As shown in the drawings, the apertures 24 and 25 in the side wall 20 of the outer casing I are sufficiently large to enable the knobs 50, 51 on the respective spindles 48, 49 to pass therethrough, thus permitting the wall 20 to be folded across the side of the casing and its flap 22 tucked into the casing after the frame and roll assembly has been inserted into the casing so as to dispose the strip or web 47 across the opening 3 in the front 2 of the casing.

The interconnecting web 30 which extends between the strips 28, 29 of the frame 27, at the upper edges thereof, serves to support the strip or web 47 in a flat condition just beneath the opening 3. The casing may be maintained in its closed position after insertion of the frame and roll assembly by the frictional engagement of the tuck flap 22 with the contiguous wall of the casing, or it may be permanently affixed to the wall of the casing by means of an adhesive, as previously described.

The operation of the invention will be obvious from the foregoing description in the light of the illustrations in the drawings and may be briefly summarized as follows: After assembly of the casing and frame and roll unit has been completed, rotation of the knob 50 at the upper end of the assembly as viewed in Figure 1 will cause the strip or web 47 to be withdrawn from the roll 45 and wound upon the roll 46. As the strip 47 passes across the opening 3 in the front wall of the casing, the printed matter on the strip will be presented to view progressively, and by rotating the knob 50 from time to time, the story and/or pictures borne by the strip or web 47 will be revealed in sequential order.

After the strip or web 47 has been unwound from one roll, as for example, 45, onto the other roll, as for example, 46, it may be rewound onto the roll 45 by suitable manipulation of the knob 51.

It is to be understood that while the invention herein described is especially adapted for use by children, its use is not necessarily so confined, as it is equally adaptable as a medium for displaying any type of intellectual conceptions to adults. The intellectual conceptions may have the form. of advertising matter, compositions of fact or fiction, with or without pictorial or graphic illustrations.
