ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to book markers, and more particularly to a book marker having a two or more selectively independently operable clamps for securing in place separate pages, or multiples of pages, in a single book.
BACKGROUND OF THE INVENTION
Book marks are well known, and in their simplest form, which almost certainly dates back to the earliest books, comprise a length of fabric, such as ribbon, which rests between the leaves of a book. Since the days of these simplest of book marks, numerous improvements and modifications have been made.
One common need among bibliophiles is the ability to simultaneously mark or identify several places in a single book. For instance, it is often expedient to know the location in a book of the end of a chapter currently being read, as well as the reader's current place in the book preceding that chapter's end. Notwithstanding the various improvements embodied in the prior art, however, there continues to exist the need for a simple and efficient book marker which can be economically manufactured and which will avoid the failings associated with prior art book marks, while providing for the securement of multiple pages, or collections of pages, in a single book.
SUMMARY OF THE INVENTION
The objects and advantages of the present invention are accomplished by a book marker comprising at least first, second, and third jaw members, the first and second jaw members being hingedly connected at a common pivotal axis to define a first independently operable clamp selectively positionable between clamped and unclamped positions thereof, and the second and third jaw members being hingedly connected at a common pivotal axis to define a second independently operable clamp selectively positionable between clamped and unclamped positions thereof. According to this arrangement, the second jaw member is intermediate of the first and third jaw members such that each of the first and second clamps comprise a pair of jaws including the second jaw member and one of the first or third jaw members.
According to one feature of this invention, means are provided for independently selectively actuating the first and second clamps between the clamped and unclamped positions thereof.
According to another feature of this invention, the first and second clamps are biased towards the clamped positions thereof, for example by a spring or other suitable biasing means.
According to yet another inventive feature, the common pivotal axis between the first and second jaw members, and the common pivotal axis between the second and third jaw members, comprise separate pivotal axes which are offset relative to each other. According to this feature, the means for independently selectively actuating the second clamp are positioned relative to the pivotal axis between the first and second jaw members so that actuation of the second clamp does not simultaneously actuate the first clamp.
