Description
Technical Field
The present invention relates to binders for stacks of paper in general, and more specifically to a binder that also functions as a stand to contain and angularly support a stack of unburst computer printout paper.
Background Art
Previously, many types of separate binders and stands have been used in endeavoring to provide an effective means to protect and handle a stack of computer printout paper, as well as to simultaneously accommodate the paper when opened to a particular place. Most prior art with this background employs rings to bind the papers together and various shapes and forms of covers to allow one of the covers to be retained in an angular position.
A search of the prior art did not disclose any patents that read directly on the claims of the instant invention, however, the following U.S. patents were considered related:
Kinneir teaches a portable lectern using conventional rings with a rigid base member shaped in such a way that a wall flange and lip create a separate angular base in conjunction with the binder that allows pages to be opened and lean against the angled base member. The support means are located on one side of one edge and becomes selectively removable from the binder or may be stored therein for transportation.
Krikorian employs a holding mechanism mounted on the back panel of one of the outer covers in the form of an easel. The member engages the ring wires and holds the cover to an outer limit of normal pivotal movement at an oblique angular relation. The other cover is free to swing into a back to back relationship. The back cover being horizontal and the easel support angular, allows the sheets to be freely turned on the wire rings to and fro in an inclined position.
Moore, on the other hand, uses a generally U-shaped element affixed to the interior of the backbone of a bound book with a foldable strip connected between the front cover and the element limiting opening movement over a preselected arc. Further, opening results in joint rotational movement with the front cover prevented from becoming coplanar reducing the amount of rotation of the pages as they are turned providing a relaxed and stable paging of the book.
Doty et al teaches a console mounted looseleaf binder having a plurality of horizontally arranged binders in evenly spaced horizontal rows such that looseleaf sheets are extended in flat orientation. A hinged top opens at a predetermined angular displacement controlled by a hinged stop allowing the pages to rest thereupon in the open position.
Ericson improves a display binder by the addition of a pair of stop arms that engage an elongated still plate flushing engaging a portion of the inner face of a back panel. This arrangement allows the flat back to rest on a horizontal surface with the front panel extended upwardly. The paper leafs or sheets are attached to the rings and are rotated upwardly and rest upon the vertical front panel in an open manner allowing pages to be opened and retain their position for reading.
Disclosure of the Invention
Since the wide spread use of computers has overtaken almost every facet of business, a problem has arisen that has not been completely addressed. Computers print out a special type of paper that is folded continuously in a fan-like manner and perforated to be torn or burst into individual sheets. The computer paper, or data processing forms, in most cases, are processed in printers that require holes on each side to hold the paper while imprinting. The problem arises that the computer paper may be read in the stack as it is attached together and, yet, the folds are on either side requiring reading the printout from the end rather than having the connecting on one side, like a book. The classic method of attaching a stack of paper together is by binding a fold into a book or punching holes and attaching with rings, staples, or pins. An attempt to solve the problem has been made by using a two-piece binder with top or bottom loading, nylon cables, or metallic clips, penetrating the uppermost set of holes with the covers top and bottom. While this type of binder does confine the stack of paper, it is still extremely difficult to hold it open requiring both hands, or even a heavy weight to maintain this position.
It is, therefore, a primary object of the invention to hold computer printout together, confined within a top and bottom cover and, yet, have the capability of opening to any page without bending the paper, except at the fold. This is accomplished by having a pair of vertical retainers on a bottom base or cover maintaining the integrity of the stack with a hinged top cover that restrains the stack in like manner on the opposite end when closed and becomes a stand when open. This arrangement does not grip the printout at all, instead, it retains it on the edges and the hinged cover simply folds back and is supported at an angle, thereby completely eliminating the need for two hands or trying to bend a large stack of paper to find the desired page. Further, as the printout is contained by folds on both edges, it is not like a stack of loose papers, instead, it maintains its shape and is easily handled when contained only on the edges.
An important object of the invention is directed toward the ability to view the entire page since it is not bound on an edge. When the binder is opened, the top cover is angled open and the stack is opened completely exposing both the top and bottom pages.
Another object of the invention is the ease in which the top cover is opened and supported at an angle. In both embodiments taught, the top cover is opened with one hand and the diagonal support folds outward by its own weight and is automatically locked in place, allowing a quick and ready reference when opening the binder for use.
Still another object of the invention provides organization for any convenient number of pages or height of the stack of computer printout paper, as the binder is adjustable in height and automatically compensates for thickness by relocating the top cover relative to the bottom base. With this arrangement no manual adjustment is required and as the stack is not permanently attached, the cover may be used by any number of stacks by simply placing it inside when in use and replacement by others when desired.
Yet another object of the invention allows the printout to be read using a minimum of desk space, as the top cover is braced open at an angle not actually touching the desk at all, minimizing the area required. The invention also keeps the stack neat while protecting the edges and is completely flat, unlike ring binders, for storing a number of binders together in a vertical stack.
A final object of the invention provides a flat, easy to write on surface for both the horizontal pages and those opened angularly. A place finder may be utilized consisting of a flat straight edge with a resistant surface on the side next to the paper to hold ones place when reading a line of printed indica.
These and other objects and advantages of the present invention will become apparent from the subsequent detailed description of the preferred embodiment and the appended claims taken in conjunction with the accompanying drawings.

Best Mode for Carrying Out the Invention
The best mode for carrying out the invention is presented in terms of a preferred and a second embodiment. Both embodiments are primarily designed with the same basic elements, except the second embodiment is slightly simpler in construction.
The preferred embodiment, as shown in FIGS. 1 through 8 is comprised of a bottom base 20 or cover of a rigid material having sufficient structural integrity to cover and partially enclose an unburst computer printout stack. This base 20 may be of any material suitable for the application, such as wood, metal, composition board, fabric covered cardboard, and the like, with thermoplastic being preferred in single or multiple layers. The thermoplastic may be polyvinyl chloride, polycarbonate, cellulose, polystyrene, polypropylene, polyester, etc.
A pair of vertical retainers 22 extend outward from the top surface of the base 20 and are either integral with or connected thereunto. Each retainer 22 contains a perpendicular slot 24 near the outside edge and the retainers are so configured as to contiguously engage and constrain a computer printout stack therebetween, as one retainer is located on each side of the stack. The retainers 22 are oblong and longitudinally parallel with the edge of the base 20 and are sufficiently high to act as a barrier for any height stack.
A top cover 26 is positioned on top of the computer printout stack directly in line with the bottom base 20. This cover 26 has a parallel center portion with raised sides 28 and acts as a protective shield and also as a stand when rotated open. The top cover 26 further contains a pair of angular stops 30 located near corners of each side opposite the vertical retainers 22 on the base cover 20. These stops 30 function in the same manner as the retainers 22, except they are on the top cover, instead of the base.
The cover 26 contains hinge means in the form of a pair of downwardly depending brackets 32 with inwardly projecting pivot pins 34. The brackets 32 are contiguous with the retainers 22 and the pins 34 slidingly interface with the slots 24 in the retainers, thereby captivating the cover 26 attaching it to the base in a rotatable manner and allowing expansion or retraction therebetween. The cover 26 rotates at least 160 degrees from a closed position in the preferred embodiment limited by the position of the slots 24 and pins 34 relative to the retainers 22 and brackets 32.
A hinged diagonal support brace 36 is pivotally joined to the top cover 26 creating a structural stand between the top cover 26 and the surface upon which the binder is positioned. The brace 36, as shown removed from the invention in FIG. 8, consists of a first hinge 38 that is attached permanently to the bottom base 20 allowing axial rotation and a first horizontal member 40 extending the support brace and also allowing rotation thereof. A second hinge 42 is attached to the first horizontal member 40 allowing compensation for the thickness of the computer printout with a second horizontal member 44 attached to the second hinge 42 providing adequate length for the brace to angularly support the cover. A third hinge 46 is attached to the second horizontal member 44 allowing the support brace 36 to bend, creating the proper functional angle for the top cover 26. A diagonal member 48 is attached to the third hinge 46 on one end with the other end contiguously engaging the top cover 26 providing a compression diagonal truss for transmitting the weight of the printout to the surface upon which the brace is resting securely holding the cover 26 open.
Means to retain the diagonal brace in an angular position consists of a spindle 50 on the outermost edge of the hinged diagonal support brace wider than the brace itself. Further, the top cover 26 contains an overhanging lip 52 within the parallel center portion 28. The spindle 50 is contained within the lip 52, thereby supporting the brace 36 in a slideable manner. When the top cover 26 is opened the brace 36 slides downward and outward by the hinge action, automatically unfolding the brace into the extended and angular position. The relation of the angle of the brace 36 and the binding action of the spindle 50 against the overhanging lips 52 lock the brace in place.
At least a pair of resilient bottom paper stack restraints 54 are attached to the bottom base 20 near the retainers 22 to prevent the computer printout from slipping when the majority of the paper is rotated upwards on the opened to cover 26. The restraints 54 consist of a resilient material, such as silicone mastic, that is formed with an irregular top surface that provides a gripping action to the printout stack. The restraint 54 is permanently bonded to the base 20.
The second embodiment is illustrated in FIGS. 9 through 16 and is basically the same as the preferred embodiment, except simpler in construction. The bottom base 20a is the same, except it is a single thickness and the upstanding vertical retainers 22a are angular in form engaging both the sides and ends of the printout stack. The base 20a further contains a pair of integral side barriers 56 projecting upward from the corners opposite the retainers 22a. Interfacing with these barriers 56 are a pair of double downwardly distended support brackets 58 interfacing on each outside surface of the barriers 56 so as to interlock the top cover 26a onto the base 20a when closed. In this embodiment, the hinge means integral with the top cover is defined by a shaft 62 somewhat wider than the cover 26a that interfaces with the slots 24a in the retainers 22a in a rotatable slideable manner.
The raised sides of the parallel center portion 28a of the top cover 26a contain a pair of opposed holes 60 for attachment of the diagonal support brace 36.
The hinged diagonal support brace 36a consists of an extended integral hinge rod 57 positioned near the end of the brace 36a rotatably penetrating the holes 60 in the top cover 26a allowing the brace 36a to rotate within the confines of the center portion 28a. The binding action of the diagonal support brace 36a against the top cover 26a relative to the rod 62 in the hole 60 provide the retaining means to maintain the brace 36a in a secure angular position.
The balance of the elements for the second embodiment are identical in function as that in the preferred embodiment.
In operation, either embodiment function the same, the only difference is that the top cover 26a is capable of opening a full 180 degrees in the second embodiment. In both configurations a stack of computer printout paper is placed in the binder of a thickness anywhere from a few sheets to a stack having a height equal to the expanded distance between the base 20, 20a and the cover 26, 26a. The retainers 22, 22a, stops 30, and barriers 56 hold the printout securely in place from the sides and the binder may be handled, stored, or stacked in a conventional book like manner. The binder may be placed on a flat surface and opened with the brace 36, 36a automatically folding outwardly to the predetermined angle and lock into place allowing the printout to be opened and the top portion rest upon the opened cover 26, 26a. In this position the printout is fully visible and easy to handle and either surface may be written upon easily and the information on a given line may be kept by the use of a flat straight edge with a resilient surface on the underside.
While the invention has been described in complete detail and pictorially shown in the accompanying drawings, it is not to be limited to such details, since many changes and modifications may be in the invention without departing from the spirit and the scope thereof. Hence, it is described to cover any and all modifications and forms which may come within the language and scope of the appended claims.
