Abstract
Abstract A holder for an open book of the paperback type has a pair of spaced leaf edge contact components that are interconnected by an expandable connecting component adapted for insertion between pages of the held book. The leaf edge contact components feature bendable portions that are equipped with a detent that overlies portions of one of the open pages and one of the contact components has a tab that overlies a portion of the other open page. Page guiding edges are provided on the detents and provisions are made for preventing withdrawal of the interconnecting component during use of the device.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
259 words
A holder for an open book comprising a pair of leaf edge contact components which are spaced apart and arranged to extend transversely of and at the respective opposite ends of the binding edge of the open book, and a connecting component which extends between and interconnects said contact components; each of said leaf edge contact components including a resiliently deformable portion which has a detent that is arranged to normally overlie and contact a marginal portion of one of the open pages of the open book and which is bendable to permit deflection of the detent in the general plane of the open book from its normal position to another position that is offset from the edge of a page contacted at its normal position, the marginal portion being laterally offset from the binding edge of the open book; one of said leaf edge contact components having a tab that is arranged to overlie and contact a marginal portion of the other of the open pages and which is laterally offset from the binding edge of the open book; said connecting component being arranged for insertion between pages underlying the other of the open pages of the open book, and each of said edge contact components having means arranged to engage the open book along its binding edge and to cooperate with the means of the other of said contact components in limiting withdrawal movement of said connecting component from between the pages underlying the other of the open pages of an open book held by the holder.
Claim 2
Dependent Claim
259 words
A holder for an open book comprising a pair of leaf edge contact components which are spaced apart and arranged to extend transversely of and at the respective opposite ends of the binding edge of the open book, and a connecting component which extends between and interconnects said contact components; each of said leaf edge contact components including a resiliently deformable portion which has a detent that is arranged to normally overlie and contact a marginal portion of one of the open pages of the open book and which is bendable to permit deflection of the detent in the general plane of the open book from its normal position to another position that is offset from the edge of a page contacted at its normal position, the marginal portion being laterally offset from the binding edge of the open book; one of said leaf edge contact components having a tab that is arranged to overlie and contact a marginal portion of the other of the open pages and which is laterally offset from the binding edge of the open book; said connecting component being arranged for insertion between pages underlying the other of the open pages of the open book, and each of said edge contact components having means arranged to engage the open book along its binding edge and to cooperate with the means of the other of said contact components in limiting withdrawal movement of said connecting component from between the pages underlying the other of the open pages of an open book held by the holder.
Claim 3
Dependent Claim
26 words
A holder for an open book in accord with claim 1 where said component is extendible to permit expansion of the space between said contact components.
Claim 4
Dependent Claim
48 words
A holder for an open book in accord with claim 1 where said connecting component maintains said contact components in spaced relation and includes cross ribs that are integrally joined and resiliently deformable to permit extension of the component and relative movement of the contact components interconnected thereby.
Claim 5
Dependent Claim
58 words
A holder for an open book in accord with claim 1 where said connecting component has opposite ends and includes a pair of wedge members which are located at the respective opposite ends of said connecting component for maintaining the cooperating means in engagement with and along the binding edge of an open book held by the holder.
Claim 6
Dependent Claim
58 words
A holder for an open book in accord with claim 1 where each of said contact components has a rigid portion, where said connecting component has opposite ends which are integrally joined to the respective rigid portions of said contact components, and where said tab is integrally joined to the rigid portion of said one of said components.
Claim 7
Dependent Claim
94 words
A holder for an open book in accord with claim 5 where said connecting component maintains said contact components in spaced relation and includes cross ribs that are integrally joined and resiliently deformable to permit extension of the connecting component and relative movement of the contact components interconnected thereby, and where said connecting component further includes a pair of wedge members which are located at the respective opposite ends of said connecting component for maintaining the cooperating means in engagement with And along the binding edge of an open book held by the holder.
Claim 8
Dependent Claim
32 words
A holder for an open book in accord with claim 1 where said detent has a page guiding edge arranged to incline upwardly and outwardly from an underlying open page contacted thereby.
