Abstract
Abstract An improved rainshed binder is disclosed for protecting a book from environmental weather conditions. The binder has first and second covers each of which have rainshed protecting walls connected to inside surface side edges of the covers. An integral binder backbone connects the first and second covers. The backbone has a pair of linear polyethylene hinges positioned inwardly of outer rigid, non-flexible corners of the backbone. The backbone connects in integral manner with the first and second covers at the rigid corners. An attachment plate secures the book to be protected to the backbone between the flexible hinges. The rigid corners of the backbone are free to flex relative to the book attachment plate by the provision of the hinges. The binder is designed to hang downwardly in closed fashion when the book is not in use. By providing the hinges inwardly of the rigid corners of the backbone, a center of gravity of each of the covers and connected rainshed protecting walls is laterally outwardly of the hinges so as to create an inwardly directed force for each of the covers so as to cause the rainshed protecting walls to overlap one another in a closed fashion.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
137 words
A rainshed binder for protecting a book from environmental conditions, comprising: (a) first and second covers; (b) a rainshed protecting wall connected to the covers; (c) a binder backbone connecting the first and second covers, said backbone having a pair of hinge means inwardly of outer rigid non-flexible corners of the backbone, said rigid corners connecting the backbone to the covers; (d) a book attachment means secured to the backbone between the hinge means, the rigid corners of the backbone being free to flex relative to the book attachment means; and (e) hanging means attached to the backbone for suspending the binder with a protected book in a downward closed position; whereby the inwardly positioned hinge means cause closing of the binder covers and attached rainshed walls by gravitational forces acting on the covers and rainshed walls.
Claim 2
Dependent Claim
137 words
A rainshed binder for protecting a book from environmental conditions, comprising: (a) first and second covers; (b) a rainshed protecting wall connected to the covers; (c) a binder backbone connecting the first and second covers, said backbone having a pair of hinge means inwardly of outer rigid non-flexible corners of the backbone, said rigid corners connecting the backbone to the covers; (d) a book attachment means secured to the backbone between the hinge means, the rigid corners of the backbone being free to flex relative to the book attachment means; and (e) hanging means attached to the backbone for suspending the binder with a protected book in a downward closed position; whereby the inwardly positioned hinge means cause closing of the binder covers and attached rainshed walls by gravitational forces acting on the covers and rainshed walls.
Claim 3
Dependent Claim
114 words
A rainshed binder for protecting a book from environmental conditions, comprising: (a) first and second covers; (b) a rainshed protecting wall positioned along peripheral edges of each of the first and second covers, said protecting wall being substantially orthogonal with respect to a planar surface of the covers; (c) a binder backbone extending between the first and second covers, said backbone having a central portion and first and second corner portions, said corner portions each comprising a rigid right angle non-hingeable connection between the backbone and the respective first and second covers; and (d) first and second hinge means for respectively attaching the backbone central portion to the first and second backbone corner portions.
Claim 4
Dependent Claim
114 words
A rainshed binder for protecting a book from environmental conditions, comprising: (a) first and second covers; (b) a rainshed protecting wall positioned along peripheral edges of each of the first and second covers, said protecting wall being substantially orthogonal with respect to a planar surface of the covers; (c) a binder backbone extending between the first and second covers, said backbone having a central portion and first and second corner portions, said corner portions each comprising a rigid right angle non-hingeable connection between the backbone and the respective first and second covers; and (d) first and second hinge means for respectively attaching the backbone central portion to the first and second backbone corner portions.
Claim 5
Dependent Claim
18 words
The binder of claim 2 in which the hinge means comprises a thinned section of flexible plastic material.
Claim 6
Dependent Claim
23 words
The binder of claim 3 in which the hinge means is integral with the backbone and comprises the same material as the backbone.
Claim 7
Dependent Claim
14 words
The binder of claim 3 in which the hinge means comprises modified linear polyethylene.
Claim 8
Dependent Claim
20 words
The binder of claim 2 in which the hinge means comprises a section of thermoplastic having depressions on opposite surfaces.
Claim 9
Dependent Claim
24 words
The binder of claim 2 in which the binder backbone, first and second covers, and hinge means are integral and of one piece construction.
Claim 10
Dependent Claim
63 words
The binder of claim 2 in which the first and second hinge means are positioned such that when the book is in a hanging position with the backbone horizontal, the first and second hinge means are laterally inwardly of the respective center of gravity points of the combined mass of the first and second covers, respective rainshed protective walls, and backbone corner portions.
Claim 11
Dependent Claim
29 words
The binder of claim 8 in which protective walls on the first cover overlap the protective walls of the second cover when the binder is in said hanging position.
Claim 12
Dependent Claim
45 words
The binder of claim 2 in which an attachment means is provided for mounting a book to be protected to the central portion of the backbone, said backbone first and second corner portions being free to swing away from edge portions of the attachment means.
Claim 13
Dependent Claim
35 words
The binder of claim 10 in which the attachment means comprises a plate connected to the backbone central portion, said plate having a wire retaining means for supporting interaction with the book to be protected.
Claim 14
Dependent Claim
46 words
The binder of claim 2 in which an attachment means is provided for mounting a book to be protected to the central portion of the backbone, said attachment means having a width less than a distance between center lines of the first and second hinge means.
Claim 15
Dependent Claim
165 words
A rainshed binder for protecting a book from environmental conditions, comprising: (a) first and second covers; (b) first and second rainshed protecting walls at an inside surface of each cover and respectively positioned along first and second edges of the covers, said protecting walls being substantially orthogonal with respect to a planar surface of the covers; (c) a binder backbone extending between the first and second covers, said backbone having a central portion and first and second corner portions, said corner portions each comprising a rigid right angle non-hingeable connection between the backbone and the first and second covers; (d) first and second hinge means for respectively attaching the backbone central portion to the first and second corner portions, said hinge means integral with and of the same material as the backbone and comprising a flexible section of thinned polyethylene; and (e) book attachment means mounted to the backbone central portion, said backbone corner portions being free to swing away from the book attachment means.
