BOOKMARK Filed July 22, 1960 w t q INVENTOR 3 1 1 j 42 Harry GPOLZ ATTORNEYS United States Patent 3,036,547 BOOKMARK Harry Groll, 24 E. Dale Road, Wilmington 3, Del. Filed July 22, 1960, Ser. No. 44,672 6 Claims. (Cl. 116-119) This invention relates to a simple and compact form of a bookmark which is capable of designating both line and page.
A relatively permanent form of bookmark should be attractive and durable as well as simple and compact. When such a bookmark must be capable of designating line as well as page, it becomes difficult to make it compact enough to lie conveniently within the pages of a closed book.
An object of this invention is to provide an attractive, simple and compact form of bookmark capable of designating page and line.
Another object is to provide such a bookmark which is capable of designating one of the two pages between which it lies.
In accordance with this invention, a hook is attached to at least one end of a stem. Slidable means connect a movable plate to this stem for permitting it to be aligned with a selected line upon a page of the book when the rod is longitudinally disposed within the crevice formed between the pages of the book with the hook hooked over the head. This bookmark is adapted for indicating one of the two pages between which it is disposed by hinging an indicating element to an end of the plate in a manner which permits substantially full rotation of the indicating element about the plate. The indicating element is folded adjacent the side of the plate next to the page to be indicated.
Novel features and advantages of the present invention will become apparent to one skilled in the art from a reading of the following description in conjunction with the accompanying drawings wherein similar reference characters refer to similar parts, and in which:
FIG. 1 is a perspective view of an embodiment of this invention in two modes of attachment to a book;
FIG. 2 is a perspective view of another embodiment of this invention;
FIG. 3 is an enlarged perspective view of the embodiment shown in \FIG. 1; and
FIG. 4 is a cross-sectional View taken through FIG. 3 along the line 4-4.
FIG. 1 shows in full line a bookmark attached to the top 12 of book 14 in a manner designating a line 16 upon the opened right-hand page 18.
This bookmark .10 includes a stem made in the form of a slender rod 20 of relatively stifr material. Rod 20 is, for example, a round metal wire. When bookmark 10 is made of precious metals, rod 20 may be made of sterling silver wire, and other materials such as stainless steel or even plastic may be used in accordance with appearance and price considerations.
A hook 22 is formed at the top of rod 20 for holding it longitudinally aligned within the crevice 24 formed between the pages 18 and 26 of hook 14 when hook 22 is hooked over the head 28 of book 14. I-look 22 is, for example, integrally formed together with rod 20 from a single length of slender relatively stiff material. Furthermore, the tip 30 of book 22 is outwardly inclined to facilitate its hooking over head 28. In addition, the disposition of hook 22 closely adjacent rod 20 facilitates the insertion of tip 30 within the space 32 between the head 28 and back of the book.
A movable plate 34 is attached to slide up and down along rod 20 by a slidable connecting means 36 which is made, for example, by a rolled loop 38 at the end of 3,i 35,547 Patented May 29, 1962 plate 34. Rod 20 is inserted within rolled loop 38, and plate 34 is accordingly slid up and down along rod 20 to designate the proper line. The insertion of rod 20 within rolled loop 38 also permits rotation of plate 34- about the axis of rod 20 which facilitates its operation and enclosure within the book. Plate 34, as was true with respect to rod 20, may be made of precious metals or relatively inexpensive materials such as plastic in accordance with appearance and price considerations. Furthermore, it may be decorated with indicia such as initials 40 to make it more attractive or to personalize it.
An indicating element 42 made in the form of a finger 42 is mounted upon the end of plate 34 by a hinge means 44 which permits substantially full 360 rotation of the finger about plate 34. Finger 42 may accordingly be folded adjacent the side of plate 34 next to the page to be indicated to designate whether the indicated line is disposed upon the right-hand page 13 or the left-hand page 26.
Hinge means 44, as shown in detail in FIGS. 3 and 4, is formed, for example, by a loop 46 formed upon the end of plate 3'4 which is engaged by longitudinal prongs 48 extending from upper and lower portions of the end of finger 42 disposed adjacent plate 34.
FIG. 1 also shows in phantom outline a bookmark 10A identical to bookmark it which is disposed in an inverted position within the pages of book 14. This indicates how a rod 28 only slightly longer than half the length of the book page can be utilized to point to any line upon the page. This inversion also turns the indicia upside-down; however, this can be avoided by the embodiment shown in FIG. 2 which is later described in detail, or by slipping the plate 34 oil the end of rod 20 and turning it around which might be slightly inconvenient.
FIG. 1 also shows the position of finger 42A for designating a line upon the left-hand page 26, whereas the alternate position 42 of finger 42 in FIG. 1 shows its position for indicating a line upon right-hand page 18. These positions are also indicated in the various positional phases of bookmark 1% shown in full line and phantom in FIG. 4.
FIG. 2 shows another embodiment 10B of this invention which includes hooks 22B and 223 mounted at opposite ends of rod 203 in a common plane and extending in opposite directions. This permits bookmark 10B to be hooked from either the top or bottom of the book in order to maintain indicia 40B, which is for example a cutout monogram, right-side-up regardless of the end E book 14 from which it is hooked. Furthermore, the opposite extensions of hooks 22B and 2213 within a common plane permits the pages of the book to be folded close together about the enclosed hook. Bookmark 10B is otherwise quite similar to bookmark ill in including an indicating plate 348 and an indicating finger 42B of slightly diflerent form and appearance. In addition hinge means 448 includes a pin 50B extending through a pintle 523 with the end of the plate 343 and gudgeons 543 formed upon the end of indicating finger 42B.
What is claimed is:
1. A bookmark comprising a slender stem, a hook connected to said stem for catching over the head of said book when said stem is disposed within the crevice formed between the pages of said book for supporting said stern within said crevice, a movable plate, a sleeve coupling means connecting said plate to said stem for permitting said plate to be moved longitudinally and up and down said stem and to be rotated about it, a line indicating element, and hinge means connecting one end of said line indicating element to the free end of said plate in a manner which permits rotation of said indicating element about said plate whereby said line indicating element may be folded within the pages of said book upon either side of said plate to designate upon which side of said plate is the page bearing the line to which said indicating element is pointing.
2. A bookmark as set forth in claim 1 wherein said stem is made of a slender rod of substantially stifi material.
3. A bookmark as set forth in claim 2 wherein said hook is integrally formed from an extension of said rod.
4. A bookmark as set forth in claim 2 wherein said rod is a relatively stiff piece of round wire.
5. A bookmark as set forth in claim 2 wherein hooks are formed upon both ends of said rod, and said hooks extending in opposite directions in a common plane.
6. A bookmark as set forth in claim 1 wherein said plate includes loops at both of its ends for providing said sleeve coupling and said hinge means.
