Description

La présente invention concerne un tamis de maçon comportant une toile de tamisage transversale maintenue dans une monture périphérique cylindrique présentant une gorge annulaire dans laquelle est logé le bord de la toile de tamisage .The present invention relates to a mason's screen comprising a transverse screen fabric held in a cylindrical peripheral mount having an annular groove in which is housed the edge of the screen fabric.

On connaît déjà, ainsi qu'il est décrit dans le modèle d'utilité allemand 1 897 241, un tamis de maçon comportant une monture périphérique cylindrique d'une seule pièce, en matière rigide telle que bois, métal, ou matière plastique, laquelle est fendue et pourvue d'un dispositif de fermeture permettant de serrer la monture cylindrique d'une seule pièce autour du bord de la toile de tamisage transversale. Un tel tamis, s'il permet de changer la toile de tamisage relativement aisément, n'en présente pas moins l'inconvénient d'avoir un encombrement très important qui se traduit, d'une part, par un coût de transport très élevé et, d'autre part par un volume très important qui doit être prévu pour son stockage. En outre, du fait que ces tamis sont transportés sans être emballés, ils subissent très souvent des dommages au cours d'un transport.We already know, as described in the German utility model 1 897 241, a mason sieve comprising a cylindrical peripheral frame in one piece, in rigid material such as wood, metal, or plastic, which is split and provided with a closing device making it possible to tighten the cylindrical frame in one piece around the edge of the transverse screen fabric. Such a screen, if it makes it possible to change the screen fabric relatively easily, nevertheless has the disadvantage of having a very large bulk which results, on the one hand, in a very high transport cost and , on the other hand by a very large volume which must be provided for its storage. In addition, because these sieves are transported without being packaged, they very often suffer damage during transport.

La présente invention vise à remédier essentiellement à ces inconvénients en procurant un tamis de maçon de conception particulièrement simple et pouvant être stocké sous un faible volume.The present invention aims essentially to remedy these drawbacks by providing a mason sieve of particularly simple design and which can be stored in a small volume.

A cet effet, ce tamis de maçon comportant une toile de tamisage transversale maintenue dans une monture périphérique cylindrique présentant une gorge annulaire dans laquelle est logé le bord de la toile de tamisage,est caractérisé en ce que sa monture est constituée de deux demi-coquilles identiques enroulées chacune suivant un demi-cercle et assemblées entre elles au moyen de dispositifs de fermeture assurant la liaison des bords transversaux en regard des deux demi-coquilles et coopérant entre eux pour assembler la monture cylindrique.To this end, this mason's sieve comprising a transverse sieving cloth held in a cylindrical peripheral frame having an annular groove in which the edge of the sieving cloth is housed, is characterized in that its frame consists of two half-shells identical, each wound in a semicircle and assembled together by means of closing devices ensuring the connection of the transverse edges opposite the two half-shells and cooperating with each other to assemble the cylindrical frame.

Le tamis de maçon suivant l'invention offre l'avantage que les deux demi-coquilles constituant ensemble la monture peuvent être emboîtées les unes dans les autres si elles sont réalisées en une matière plastique rigide, ou encore elles peuvent être conditionnées à plat, ce qui permet de réduire le volume nécessaire pour son stockage d'environ 83%. Ce conditionnement réduit, ainsi que le faible encombrement, permettent d'effectuer des expéditions à longues et même très longues distances, dans de bonnes conditions de coût et de sécurité. En effet, les divers éléments constitutifs du tamis (monture et toile métallique) peuvent être conditionnés dans des emballages en carton les protégeant contre tous dommages.The mason's sieve according to the invention offers the advantage that the two half-shells together constituting the frame can be fitted into one another if they are made of a rigid plastic material, or still they can be packaged flat, which reduces the volume required for its storage by about 83%. This reduced packaging, as well as the small footprint, make it possible to carry out long and even very long distance shipments, in good conditions of cost and safety. Indeed, the various constituent elements of the sieve (frame and wire mesh) can be packaged in cardboard packaging protecting them from any damage.

On décrira ci-après, à titre d'exemple non limitatif, une forme d'exécution de la présente invention, en référence au dessin annexé sur lequel :

Le tamis de maçon suivant l'invention qui est représenté sur le dessin, comporte une toile de tamisage métallique circulaire 1 dont le bord est tendu sur un cercle périphérique. le cercle périphérique peut être constitué en fait de deux cercles concentriques en fer plat 2 et 3 entre lesquels est pincé le bord de la toile l,comme il est représenté sur la figure 3 ou bien encore par un cercle unique 4 (figure 4) en fil métallique d'une section de 4mm par exemple. Dans ce dernier cas, le blocage de la toile de tamisage sur le cercle est assuré par un feuillard serti sur la toile métallique 1 elle-même enroulée sur le cercle 4.The mason's sieve according to the invention which is shown in the drawing, comprises a circular metallic sieving fabric 1 whose edge is stretched over a peripheral circle. the peripheral circle can in fact consist of two concentric circles of flat iron 2 and 3 between which the edge of the fabric 1 is pinched, as shown in FIG. 3 or even by a single circle 4 (FIG. 4) in wire of a section of 4mm for example. In the latter case, the blocking of the screen fabric on the circle is ensured by a strip crimped on the metal fabric 1 itself wound on the circle 4.

Cette toile de tamisage métallique 1 est maintenue dans une monture périphérique cylindrique qui, suivant l'invention,est constituée de deux demi-coquilles identiques 5,6 enroulées chacune suivant un demi-cercle. Chacune des demi-coquilles 5, 6 peut être constituée par un morceau de bande de matière plastique souple injectée à plat et qui est ensuite incurvée suivant un demi-cercle.De préférence chaque demi-coquille 5,6 est moulée dans une matière plastique rigide et présente une section droite en demi-cercle . Chaque morceau de bande a une forme rectangulaire et a, par exemple, une longueur de 628 mm et une largeur de 120 mm.This metallic screen cloth 1 is held in a cylindrical peripheral frame which, according to the invention, consists of two identical half-shells 5,6 each wound in a semicircle. Each of the half-shells 5, 6 may consist of a piece of strip of flexible plastic material injected flat and which is then curved in a semi-circle. Preferably each half-shell 5,6 is molded in a rigid plastic material and has a cross section in a semicircle. Each piece of tape has a rectangular shape and has, for example, a length of 628 mm and a width of 120 mm.

Les deux dei-coquilles 5, 6 sont assemblées entre elles, pour constituer la monture cylindrique, grâce à des dispositifs de fermeture 7 assurant la liaison des bords transversaux en regard des deux demi-coquilles 5, 6.Chaque dispositif de fermeture est avantageusement constitué par deux éléments mâle et femelle, prévus respectivement aux deux extrémités opposées de chaque demi-coquille 5, 6, s'em- boitant l'un dans l'autre et restant emboîtés par verrouillage élastique. On voit par exemple sur la figure 5 que la demi-coquille 5 présente, le long de son bord transversal, une languette 8 en saillie vers l'extérieur et que l'autre demi-coquille 6 présente, le long de son bord transversal en regard, une gorge 9 ménagée dans une surépaisseur 10. La languette 8 est engagée dans la gorge 9 et retenue dans celle-ci par une partie de la surépaisseur 10 formant un crochet élastique 11. Tous les éléments constitutifs du dispositif de verrouillage viennent avantageusement de moulage avec le restant des deux demi-coquilles 5 et 6.The two dei-shells 5, 6 are assembled together, to form the cylindrical frame, by means of closing devices 7 ensuring the connection of the transverse edges opposite the two half-shells 5, 6. Each closing device is advantageously made up by two male and female elements, provided respectively at the two opposite ends of each half-shell 5, 6, which fit one inside the other and remain nested by elastic locking. We see for example in FIG. 5 that the half-shell 5 has, along its transverse edge, a tongue 8 projecting outwards and that the other half-shell 6 has, along its transverse edge in manhole 9, a groove 9 made in an extra thickness 10. The tongue 8 is engaged in the groove 9 and retained therein by a part of the extra thickness 10 forming an elastic hook 11. All the constituent elements of the locking device advantageously come from molding with the remainder of the two half-shells 5 and 6.

Pour recevoir le bord de la toile de tamisage 1, chaque demi-coquille 5, 6, présente, à une distance appropriée de l'un de ses bords longitudinaux, une gorge longitu dinale 12 à section droite rectangulaire (figure 3), ou 13 à section droite semi-circulaire (figure 4). La forme de cette gorge est évidemment adaptée à celle du cercle bordant la toile de tamisage 1.To receive the edge of the screen cloth 1, each half-shell 5, 6, has, at an appropriate distance from one of its longitudinal edges, a longitudinal groove 12 with a rectangular cross section (FIG. 3), or 13 with a semicircular cross section (figure 4). The shape of this groove is obviously adapted to that of the circle bordering the screening fabric 1.

Lors du montage du tamis suivant l'invention, les deux demi-coquilles 5 et 6 sont appliquées autour de la toile de tamisage 1 de façon que le bord circulaire de celle-ci vienne se loger dans la gorge 12 ou 13 des deux demi-coquilles 5 et 6. l'assemblage est terminé par un verrouillage élastiques des dispositifs de fermeture 7.When mounting the screen according to the invention, the two half-shells 5 and 6 are applied around the screen fabric 1 so that the circular edge of the latter comes to lodge in the groove 12 or 13 of the two half shells 5 and 6. the assembly is terminated by an elastic locking of the closing devices 7.

Pour renforcer la monture, on peut prévoir sur la face externe des deux demi-coquilles 5, 6 à l'endroit des gorges 12, 13, des goussets longitudinaux 14 venant également de moulage.To strengthen the frame, one can provide on the outer face of the two half-shells 5, 6 at the location of the grooves 12, 13, longitudinal gussets 14 also coming from molding.
