Abstract

Magnetic fixing device according to any one of the claims of the main patent, characterised in that it comprises a non-magnetic or magnetic anchoring element 8 inserted longitudinally between the polar masses 1a, 1b under the lateral rims 3 and above the ferrite 2 and the length of which is greater than the length of the said polar masses to enhance the holding of the said device in the outer coating.

Description

Dispositif magnétique de fixation amélioré.Improved magnetic fixing device.

La présente invention concerne un perfectionnement à un dispositif magnétique de fixation. The present invention relates to an improvement to a magnetic fixing device.

La demande de brevet français 86-06065 décrit un dispositif magnétique de fixation qui comprend un aimant ou ferrite placé entre deux masses polaires1 caractérisé en ce que lesdites masses polaires possèdent au moins un rebord latéral destiné à empecher le glissement du ferrite entre lesdites masses vers l'extérieur. French patent application 86-06065 describes a magnetic fixing device which comprises a magnet or ferrite placed between two polar masses1 characterized in that said polar masses have at least one lateral flange intended to prevent the sliding of ferrite between said masses towards the 'outside.

Ce dispositif est destiné à etre inclus partiellement ou totalement dans un enrobage extérieur du type résine ou béton et l'ancrage de ce dernier se trouve renforcé grâce aux rebords des masses polaires, qui de plus rendent les masses polaires et le ferrite totalement indissociables. This device is intended to be partially or totally included in an exterior coating of the resin or concrete type and the anchoring of the latter is reinforced by the edges of the polar masses, which moreover make the polar masses and the ferrite completely inseparable.

La présente invention vise un perfectionnement à ce dispositif magnétique permettant d'améliorer la tenue et le positionnement du dispositif dans son enrobage extérieur. The present invention provides an improvement to this magnetic device making it possible to improve the strength and positioning of the device in its outer coating.

Selon une première caractéristique de l'invention, le dispositif magnétique de fixation selon l'une quelconque des revendications du brevet principal est caractérisé en ce quil comprend un élément d'ancrage amagnétique inséré longitudinalement entre les masses polaires, sous les rebords latéraux et au-dessus du ferrite et dont la longueur est supérieure à la longueur desdites masses polaires pour renforcer le maintien dudit dispositif dans l'enrobage extérieur. According to a first characteristic of the invention, the magnetic fixing device according to any one of the claims of the main patent is characterized in that it comprises a non-magnetic anchoring element inserted longitudinally between the polar masses, under the lateral flanges and au- above the ferrite and the length of which is greater than the length of the said polar masses in order to strengthen the retention of the said device in the outer coating.

Selon un mode de réalisation particulier de l'invention, ledit élément d'ancrage est constitué par exemple d'une bande métallique amagnétique ou magnétique. According to a particular embodiment of the invention, said anchoring element consists for example of a non-magnetic or magnetic metal strip.

Selon une autre caractéristique de l'invention, ledit élément d'ancrage a une longueur suffisante pour former aussi un moyen de liaison entre plusieurs ferrites. According to another characteristic of the invention, said anchoring element has a length sufficient to also form a connection means between several ferrites.

Un autre objet de l'invention est une utilisation dudit dispositif pour réaliser un réseau de ferrites orientés parallèlement et destiné à être intégré dans un enrobage extérieur.  Another object of the invention is a use of said device to produce a network of ferrites oriented in parallel and intended to be integrated in an external coating.

L'invention sera mieux comprise à la lecture de la courte description qui va suivre accompagné du dessin annexé représentant une vue en perspective du dispositif de l'invention. The invention will be better understood on reading the short description which follows, accompanied by the appended drawing representing a perspective view of the device of the invention.

La figure montre les masses polaires la, lb, le ferrite 2 à section rectangulaire ou carrée venant se loger entre les deux masses polaires la, lb avec les rebords latéraux 3. The figure shows the polar masses la, lb, the ferrite 2 with a rectangular or square section coming to be housed between the two polar masses la, lb with the lateral flanges 3.

Selon l'invention, on prévoit un élément d'ancrage amagnétique 8 inséré longitudinalement entre les masses polaires la, lb, sous les rebords latéraux 3 et au-dessus du ferrite 2. According to the invention, there is provided a non-magnetic anchoring element 8 inserted longitudinally between the pole masses 1a, 1b, under the lateral flanges 3 and above the ferrite 2.

La longueur de cet élément d'ancrage 8 est supérieure à la longueur desdites masses polaires pour renforcer le maintient dudit dispositif dans l'enrobage extérieur. The length of this anchoring element 8 is greater than the length of said pole masses in order to reinforce the maintenance of said device in the external coating.

Selon un mode de réalisation avantageux, l'élément d'ancrage est constitué par exemple d'une bande métallique amagnétique ou magnétique.. According to an advantageous embodiment, the anchoring element consists for example of a non-magnetic or magnetic metal strip.

Selon un autre mode de réalisation, ledit élément d'ancrage 8 a une longueur suffisante pour former aussi un moyen de liaison entre plusieurs ferrites et masses polaires. According to another embodiment, said anchoring element 8 has a length sufficient to also form a connection means between several ferrites and polar masses.

Dans ce mode de réalisation particulier, l'élément d'ancrage est inséré longitudinalement entre les masses polaires de plusieurs dispositifs en série. In this particular embodiment, the anchoring element is inserted longitudinally between the pole masses of several devices in series.

Ce dernier mode de réalisation permet l'alignement de plusieurs ferrites dans l'enrobage extérieur. This last embodiment allows the alignment of several ferrites in the outer coating.

Si on peut réaliser un réseau de ferrites orientés parallèlement; destiné à être intégré dans un enrobage extérieur tout en conservant une bonne tenue et un meilleur ancrage.  If we can make a network of parallel oriented ferrites; intended to be integrated into an external coating while retaining good strength and better anchoring.
