Abstract

An apparatus is described in the form of a block by means of which information applied to a coated steel panel by means of a special pencil can be erased without moisture or pressure. The block, in the form of a parallelepiped or of a circular disc, adheres to the steel panel by magnetism, and the magnetic surface of the block is coated with a silk-like, velvet-like or felt-like covering which forms the erasing element. The block is moreover provided with a device for receiving a pencil which is either inserted into a semi-cylindrical groove or pushed into a hole or a short, sleeve-like attachment on the block.

Description

Il existe depuis quelques années des tableaux d'affichage en acier laqué, propres à recevoir une écriture effaçable à sec, obtenue au moyen de marqueurs spéciaux, existant également depuis peu sur le marché. Lacquered steel bulletin boards have been available for a few years, suitable for receiving a dry erasable writing, obtained by means of special markers, also existing on the market recently.

Ce procédé d'affichage par marquage effaçable à sec est attrayant, séduisant et surtout pratique, comparé au procédé classique mettant en oeuvre des bâtons de craie dont le frottement sur un tableau en bois peint, donne lieu à une poussière salissante et par fois génératrice dtallergies respiratoires ou cutanées pour l'uti- lisat eur.  This display method by dry erasable marking is attractive, attractive and above all practical, compared to the conventional method using chalk sticks whose friction on a painted wooden table, gives rise to a dirty dust and sometimes generating allergies. respiratory or cutaneous for the user.

Le marquer à utiliser, ntest généralement pas conservé sur 90i en raison de ses dimensions relativement importantes, compares à celles d'un crayon ou d'un stylographe, mais trouve couramment sa place sur un bureau ou une étagère à proximité.  The marker to use is generally not kept on 90i because of its relatively large dimensions, compared to those of a pencil or a stylographer, but commonly finds its place on a desk or nearby shelf.

La brosse ou le chiffon nécessaires pour l'effaçage trouveront également leur place à proximité du crayon marqueur. The brush or cloth necessary for erasing will also find their place near the marker pen.

Il n'est pas raie d'avoir à chercher ces objets, rapidement dissimulés sous des documents ou accessoires fort nombreux sur une table ou un bureau. It is not a good idea to have to look for these objects, quickly concealed under numerous documents or accessories on a table or desk.

Il est ainsi facile dsentrevoir la commodité d'un dispositif qui permettrait de disposer immédiatement du marqueur et de l'élément effaceur. It is thus easy to glimpse the convenience of a device which would allow the marker and the erasing element to be immediately available.

Par exemple en imaginant 11 élément effaceur sous forme dSESS bloc pousant,par attraction magnétique, titre maintenu sur le tableau en acier, en n'importe quel point de celui-ci et pouvant aussi permettre, par sa forme particulière, le maintien du marqueur à portée de la main de l'utilisateur. For example by imagining 11 erasing element in the form of a pushing block, by magnetic attraction, title maintained on the steel table, at any point thereof and which may also allow, by its particular shape, the maintenance of the marker at within reach of the user.

Le dispositif objet de la présente invention a précisément pour but de répondre à ces exigences. The object of the present invention is precisely to meet these requirements.

Il est constitué d'un bloc en bois ou en matière plastique, de forme parallèlépipédique ( mais une forme ronde pourrait également se concevoir ) dont une grande face comprend un aimant puissant, ni en retrait, ni en saillie, mais exactement dans le plan de cette face. Celle-ci se trouve recouverte d'un film feutré adhésif assez mince pour ne pas trop réduire l'action du champ magnétique. It consists of a block of wood or plastic, of parallelepiped shape (but a round shape could also be conceived) of which a large face includes a strong magnet, neither in withdrawal, nor in projection, but exactly in the plane of this face. This is covered with a felted adhesive film which is thin enough not to reduce the action of the magnetic field too much.

Cette grande face ainsi magnétique constituant la base du bloc, les flancs selon la longueur du bloc, pourront présenter une cannelure semi-cylindrique, dans laquelle pourra indifféremment être placé le marqueur, les flancs rainurés étant symétriques par rapport à un axe médian parallèle au plan magnétique. This large magnetic face constituting the base of the block, the sides along the length of the block, may have a semi-cylindrical groove, in which the marker can be placed indifferently, the grooved sides being symmetrical with respect to a median axis parallel to the plane magnetic.

Les dessins annexés illustrent à titre d'exemple un mode de réa- lisation du dispositif conforme à la présente invention
Représentent plus particulièrement:
- La figure 1, le dispositif objet de l'invention, plaqué sur tableau d'affichage;
- La figure 2, le dispositif en pièces détachées
Tel qu'il est représenté sur la figure 1, le dispositif se présente sous la forme d'un bloc parallèlépipédique 1, représenté en 6 sur la figure 2, allégé intérieurement et constitué par assemblage de différents éléments pour le cas d'une conception en matière plastique, ou bien massif et dpun seul tenant, en bois par exemple dont les flancs présentent une cannelure semi-cylindrique telle que 2 et 3 de la figure 1 ou 7 et 8 de la figure 2o Ces deux cannelures peuvent indifféremment, suivant l'orientation du bloc effa çeur sur le tableau d'affichag- recevoir un marqueur tel que 4 de la figure O..La face plaquee sur le tableau 5, invisible sur la figure 1, mais visible en 9 sur la figure 2, comporte en son centre un chambrage tel que 10 de la figure 2 propre à contenir exacte- ment et sans jeu, le circuit magnétique comprenant les blocs magnétiques il et t2, dont les champs magnétiques orientés dans le sens de l'épaisseur comme indiqué sur le figure 2, et inversés ltun par rapport à l'autre, permettent leur attraction mutuelle et du mëme coup leur assemblage naturel, ( la figure 2 les montrant séparés pour plus de clarté ), ainsi qu'une plaquette polaire 13, qui,plaquée sur ltensemble des 2 blocs 11 et 12, assure la conti- nuité du circuit magnétique. ( A noter que les 2 blocs magnétiques 11 et 12 ne pourraient nten former qu'un seul, d'une seule pièce, à aimantation bipolaire ). La cohésion de l'ensemble- est assurée par un collage appropriés Une fois cet assemblage réalisé, les faces 14 et 15 des blocs magnétiques se trouvent exactement dans le plan de la face 9. Une feuille 16, adhésive sur une face et veloutée sur l'autre, vient recouvrir la face 9 du bloc 6. Cette feuille constitue l'élément effaceur du bloc. Elle est suffisamment mince pour ne pas trop affaiblir l'action du champ magnétique du bloc.
The accompanying drawings illustrate by way of example an embodiment of the device according to the present invention
Represent more particularly:
- Figure 1, the device object of the invention, placed on a display board;
- Figure 2, the device in parts
As shown in Figure 1, the device is in the form of a parallelepipedal block 1, shown at 6 in Figure 2, lightened internally and formed by assembling different elements for the case of a design in plastic material, or solid and in one piece, made of wood for example, the sides of which have a semi-cylindrical groove such as 2 and 3 in FIG. 1 or 7 and 8 in FIG. 2o These two grooves can indifferently, depending on the orientation of the erasing block on the display board - receive a marker such as 4 in figure O..The face plate on the board 5, invisible in figure 1, but visible at 9 in figure 2, includes in its centers a recess such as 10 in FIG. 2 capable of containing exactly and without play, the magnetic circuit comprising the magnetic blocks il and t2, whose magnetic fields oriented in the thickness direction as indicated in FIG. 2, and inverted ltun with respect to the aut re, allow their mutual attraction and at the same time their natural assembly, (Figure 2 showing them separated for clarity), as well as a polar plate 13, which, pressed against all of the 2 blocks 11 and 12, ensures the conti - night of the magnetic circuit. (Note that the 2 magnetic blocks 11 and 12 could only form one, in one piece, with bipolar magnetization). The cohesion of the assembly is ensured by an appropriate bonding Once this assembly has been carried out, the faces 14 and 15 of the magnetic blocks lie exactly in the plane of the face 9. A sheet 16, adhesive on one side and velvety on the other, covers the face 9 of the block 6. This sheet constitutes the erasing element of the block. It is thin enough not to weaken the action of the magnetic field of the block too much.

Le dispositif,.objet de l'invention, peut titre utilisé dans tous les nombreux cas nécessitant-l'utilisation d'un tableau d'affichage en acier laqué, pouvant recevoir une écriture chimique effaçable à secj notamment dans les lyçées et collèges, bureaux, administrations, salles de conférences, etc. The device, object of the invention, can title used in all the numerous cases requiring-the use of a display board in lacquered steel, being able to receive a chemical writing erasable with dryness in particular in high schools and colleges, offices , administrations, conference rooms, etc.

Il peut également permettre l'utilisation de petites écritoires murales en acier laqué à usage domestique, pouvant trouver leur place dans une cuisine ou derrière une porte. It can also allow the use of small lacquered steel wall writing desks for domestic use, which can find their place in a kitchen or behind a door.
