## Title
Magnetic page marker

## Abstract

The present invention consists of a magnetic page marker comprised by a pair of laminar walls which form a clip applicable to the edge of the page that is intended to mark. Into the clip, there is a pair of magnetic means which clasp said page, whose admission into the clip is facilitated by an inner cover. The bookmark has a signalling tab which jutts out notoriously respect the edges of the pages.

## Background
I—BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention consists of a magnetic page marker which applied to books or notebooks, allows to place the marker on the page without opening the clips formed by its laminar walls where there are magnetic means with a cover for each of them.
2. Description of the Prior Art
The use of bookmarks, also called markers, is very well known to identify a book or notebook page where the reader has stopped reading, and where he wishes to come back later readily.
The simplest conventional bookmarks are elongated laminar sheets placed between the page intended to mark and the immediately prior or next one, so that it is held between both pages and with one of its ends projecting out from the set of pages, once the book or notebook has been closed.
This type of bookmark present numerous disadvantages. One of them is that, if several pages are intended to be marked by using several bookmarks, upon closing the book, the bookmarks will remain overlapped, marking the access to the different marked pages difficult.
Another disadvantage is that, as the bookmark is held by the pages by binding it, upon opening the book, it usually drops.
Australia Patent No. AU-A-47866/90 refers to a bookmark made of two magnetic elements whose respective supports are joined by a flexible means. The latter has the disadvantage of complicating the operation of placing it on the page because, until the magnetic elements stay well opposite each other, the bookmark is not fixed and may drop from the reader's hands.
South Africa Patent No. 95/8805 refers to a bookmark consisting of a pair of pieces, each of them provided with the respective magnetic elements and joined by a hinge, so that the book page lies between both pieces. In this case, the hinge is indispensable because, if a marker were placed closed (with its magnetic elements in contact), the book page would meet resistance to penetrate.
One of these difficulties may be due to a very thin page which cannot separate the magnetic elements in order to penetrate between them. The other difficulty that occurs is that the page edge impinges against the prominent edges of the magnetic means.
II—SUMMARY OF THE INVENTION
The object of the present page marker is to provide a marking means for book or notebook pages, whose laminar walls form a clip that may be placed without opening. This is because the magnetic means have a cover which facilitates the admission of the edge of the page.
OBJECTS AND ADVANTAGES
The present bookmark is comprised by a clip which clasps the page on an edge and remains fixed by the mutual attraction of the magnetic means. The cover covering thereof prevents the edge of the page from folding or impinging against the prominent edges of said magnetic means upon placing the bookmark. In consequence, it facilitates the admission of the page within the clip formed by the laminar walls and the magnetic means need not be separated manually in order to introduce the page.
Optionally, between the ends of the clip and the prominent edges of the magnetic means, the laminar walls may have laminar supplements each with similar height to said magnetic means, so that there is no unlevelling within the page admission area.
The laminar walls may have different sizes so that graphic advertising and/or ornamental prints can be applied on their surfaces, as well as forming embossment.
In addition to the inner cover, the bookmark may have an outer cover covering it totally or partially.
At the joint area between the laminar walls there may be a tab so that, once the bookmark is applied, it projects out ot the pages heap and facilitates marking.
Longitudinal edges of the laminar walls or, eventually, openings are used as line markers on the page marked.
Ornamental type openings may also be included.
The laminar walls may also serve as support for electronic devices with displays, such as flat clocks, thermometers, or calculators.

IV—DETAILED DESCRIPTION
FIG. 1 shows the bookmark comprised by a pair of adjacent laminar walls (2) (5), which have a joint (7) on one end and on the opposite end they form a clip (1) dedicated to clasp the edge (6′) of the page (6). Into the clip (1) there are two magnetic means (3)(4) having a mutual attraction force.
FIG. 2 shows the longer laminar wall (5) whose large surface (5′) can be used to apply graphic prints such as advertising messages or ornaments and whose longitudinal edge (100 is a line marking means. At the joint (7) between both walls (2) (5) a tab (7′) juts out outstanding noticeably from the edge (6′) of the page (6).
FIG. 3 shows how the edge (6′) of the page (6) is inserted into the clip (1) formed by the laminar walls (2) (5) and the magnetic means (2)(5) with the cover (9).
FIG. 3A shows an exploded view of FIG. 3, wherein it can be seen in detail the first magnetic means (3) fixed to the shorter laminar wall (2) and to the second laminar wall (4) fixed to the longer laminar wall (5). Both magnetic means (3)(4) are covered by the cover (9), particularly its prominent edges (8). Therefore, the above mentioned cover (9) prevents the impingements between the page (6) and said prominent edges (8), facilitating the entrance thereof (6) into the clip (1). FIGS. 3B, 3C show wedge elements 16 structurally arranged to cooperate with the magnetic members in order to permit the page of the book to be latterly received within the throat of the clip marker. FIG. 3C also shows outer cover members (20) borne by the external surfaces of the page marker opposite the throat opening.
FIG. 4 shows the longer laminar wall (5), whose longitudinal edges (10) serve as line marking means and from one of its transverse edges the tab jutts out (7′).
In FIG. 5, the cut shows the shorter laminar wall (2) which, in the inner part of the clip (1), has the first magnetic means fixed (3), above which there is the cover (9) (in this case, it is transparent). Recess (11) on the transverse edge results from the cut with which the tab is formed (7′).
In the present embodiment, the adjacent laminar walls (2) (5) are formed by a laminar sheet folded by means of a folding line which separates one wall respect the other.
The cover (9) may be transparent or not, and, in addition, it may be made of different materials, such as a layer of plastic or cellulosic material.
Operation
The clip (1) formed by laminar walls (2) (5) remains closed due to the mutual attraction force exerted by the magnetic means (3)(4), the page (6) being clasped in between them, such as it can be seen in FIGS. 1 and 2.
When introducing the bookmark on the edge (6′) of the page (6), the entrance of the latter (6) is facilitated by the presence of the cover (9). This is due to the fact that cover (9) facilitates the page sliding (6) and prevents the impingement between the edge (6′) of the page (6) and the prominent edges (8) of the magnetic means (3) (4), as it can be observed in FIGS. 3, 3A and 5.
The joint (7) between the shorter and longer walls (2) (5) acts as the stop of the pages (6) admission into the clip (1). Therefore, the tab (7′) is the element which outstands most from the pages (6) once the bookmark is placed, as can be seen in FIGS. 2, 3 and 4.
