ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates to leaf accessory holders, and in particular to leaf accessory holders otherwise known as mechanical “windowing” devices which can be positioned into multiple locations while still attached to a host. The new elements of the invention are a morphable leaf, which leaf itself has joined functional portions for allowing the transformation of the leaf into a multi-position device, said morphing leaf formed as a planar multi-sided structure comprising both the mounting leaf portion and the orientation leaf portion, where both the mounting leaf and the orientation leaf can be positioned into a first position to lie flat, in the same plane, and further where the orientation leaf portion can be rotationally repositioned by 180 degrees into a second location substantially adjacent itself.
This invention relates to the formation of windowing devices having mounting surfaces and orientation panels, as detailed for example, in “hypertext book attachment” U.S. Pat. No. 5,380,043 filed Mar 16, 1989, by patent holder, the one and same, David C. Schwartz. This prior art provides a working definition of windowing, to provide further clarification of the field of art for the object of invention of this application. Windowing devices are defined as devices that “can be folded into the (book on either side while retaining the same orientation of the mounting surface. This property, enabled by the orientation flap, permits retention of the orientation of the mounting surface in a plurality of positions, not only with respect to a host book but with respect to different positions of the mounting surface itself, and enables the property referred to earlier as windowing”.
Further more, this invention relates specifically to windowing leaf structures, as in “windowing leaf structure” U.S. Pat. No. 5,407,231 filed Nov. 23, 1992, by patent holder, the one and same, David C. Schwartz, where, to provide further clarification as to the general nature of the behavior of such windowing leaf structures. Using this patent, one skilled in the art would know the quoted text copied herein, from portions of columns, 1, 3, 4, 5, and 6 that states “The invention therefore relates to mounting surfaces that are attached to a flap that preserves the orientation of the face surface of the mounting surface in a plurality of locations, with respect to the book to which it is attached. This invention relates to binding systems . . . (having) . . . leafs with mounting surfaces which may be directly attached to a host book, it's bindings, it's surfaces, and or its covers, which in and of themselves provide non-sequential(non-linear) access to their mounting surfaces without needing to be removed from their attachment to the host book, it's bindings and/or it's surfaces, and which offer further non-linear access when physically removed from their binding and repositioned. The invention relates to the provision of such on-linear pages which possess the property hereinafter referred to as “windowing”, the ability for the page to maintain it's face and perimeter orientation in various positions without being removed from the host book to which they are attached, and to such pages implemented with means for semi-permanent attachment, there by offering 2 levels of non-linear access. The invention relates leaves with mounting surfaces offering semi-permanent retaining means which enable easy removal and reinsertion, and to book systems formed by combining covers, rings, and mounting surfaces according to this invention that offer highly visual means for handling information.”
This invention relates to a windowing leaf attachment structure, implemented in such a manner as to be permanently attached to a binding, semi-permanently attached to a binding, and or permanently or semi-permanently attached to any surface, such as a cover, or other surfaces, such as other pages of a host book. The binding means for attaching the surface to the book may require the opening or closing of a ring mechanism for removal and repositioning.”
This invention relates to windowing leaf structures having behaviors typically known to be in accordance with this class of windowing invention, where the prototypical embodiments known in the art provide at least two variations of surfaces implemented as windowing devices. “One retains its face and perimeter orientation in four positions about it's host coupling structure while remaining attached to it's host coupling structure. A second retains it's face and perimeter orientation in two co-planar and substantially adjacent locations about the host coupling structure, while staying attached to the host coupling structure. Either of these may be implemented with traditional holes that fix the flap to a binding. It is preferable to implement them with the insertable holes.” The four position device has a mounting surface attached to an orientation flap which is in turn attached to an extension flap. The orientation flap is attached to the extension flap via a flexible material which adds heith(clearance height) when the mounting surface is positioned to encompas interleaved sheets which might also be attached to the host book binding. The flexible material is optional. “The two position device” has a mounting surface attached to an orientation flap along a line substantially parallel to and substantially mid-way between two parallel outer edges of the mounting surface. In this variation the orientation flap has a slotted hole pattern implemented along it's parallel edge opposing the edge bound to the mounting surface. This implementation allows for the co-planar location of the mounting surface in two positions about the binding, wherein the face and perimeter orientation of the mounting surface is preserved in both substantially adjacent locations.”
It is known as a matter of prior art to one skilled in this subcategory of inventions, and by referring to at least the above two mentioned patents, that the prior art provides for a minimal set of components to construct both of the windowing devices “folded from one sheet of foldable material”, where in the construction employs two mounting surfaces, a first “mounting surface is intended to receive a second mounting surface which would be placed. thereon and would carry some form of device such as a pad”, thereby forming a windowing device which is automatically two layers thick with the third layer formed by the add on accessory itself, see the figure included following which depicts the multiple surfaces, before attaching the third layer device such as the pad. It is known that thickness is a detriment in making accessories for binders, so the purpose of the invention herein disclosed is to form such a windowing device from a minimal construction that removes one of the two layers identified above.
The publicly known solution which is most related to this invention has an integral mounting panel comprising a substantially retangular surface to which is attached by various means, an orientation panel. The orientation panel is pivotally attached at a location between the opposing ends of the the mounting panel, allowing the mounting panel to be positioned into multiple locations. The disadvantage of this structure is that the structure has double thinkness in all positions. It is also more expensive to form the publically known structures, since these structures require a folding and sealing operation, or require assembly of sections which lie in double thinkness when coincident, one with the other. The portion of material also adds an extra step in formation and makes these embodiments more expensive to manufacture.
SUMMARY OF THE INVENTION
The invention therefore relates to leaf accessory holders, and in particular to leaf accessory holders otherwise known as mechanical “windowing” devices which can be positioned into multiple locations while still attached to a host. The invention particularly relates to such leaf accessory holders where the leaf is formed itself as a
