Abstract

The invention relates to a painting roller consisting of a cylinder 1 with ribs 4, which is smooth inside. One side is closed and fitted with a threaded joining piece 3, the other side is open 3 and provided with two guiding grooves 8. Two slots 7 are provided along the cylinder which enable the paint coming from the cartridge to be discharged between the ribs 4. The whole assembly is covered by a sleeve 5, and a bent handle passes through the cylinder, with a nut solidly fixing the handle to the roller. The cartridge, storing paint, is introduced into the roller via the rear, and is correctly positioned by means of its guiding grooves, and opened on two sides by two blades 10 which are placed at the start of the slots in the cylinder. By turning the cartridge to the left, the openings will be positioned opposite the slots and will allow the paint to be discharged towards the hollow parts 6 between the ribs 4.

Description

La présente invention concerne un rouleau à peindre à cartouches jetables pour donner une certaine autonomie au rouleau à peindre, il existe une variante à réservoirs, c'est-à-dire un cylindre perforé garni d'un manchon on remplit le réservoir de peinture qui s'écoule par les perforations et imbibe le manchon ce procédé a pour inconvénient d'être très salissant pendant l'utilisation, notamment le remplissage.The present invention relates to a paint roller with disposable cartridges to give a certain autonomy to the paint roller, there is a variant with reservoirs, that is to say a perforated cylinder fitted with a sleeve, the paint reservoir is filled which flows through the perforations and soaks the sleeve this process has the disadvantage of being very dirty during use, in particular filling.

Le dispositif, selon l'invention permet de remédier à cette la cune En effet, la peinture est contenue dans une cartouche cylindrique formant magasin à peinture qui est elle-même engagée dans le rouleau à peindre proprement dit. une fois vide, cette cartouche est retirée et remplacée par une cartouche pleine
Un autre inconvénient que l'on rencontre dans le rouleau à réservoir perfo9',est que l'on ne peut jamais arrêter l'alimentation pendant le travail, ce qui nuit à sa bonne exécution.The device according to the invention makes it possible to remedy this problem. In fact, the paint is contained in a cylindrical cartridge forming a paint store which is itself engaged in the paint roller itself. once empty, this cartridge is removed and replaced by a full cartridge
Another disadvantage which one meets in the roller with tank perfo9 ', is that one can never stop the feeding during the work, which harms its good execution.

Un autre objet, selon l'invention, consiste à régler le débit de la peinture en provenance de la cartouche.Another object, according to the invention, is to regulate the flow of paint from the cartridge.

Le rouleau, selon cette invention, comporte un cylindre fermé d'un cûté et muni d'un embout fileté perforé par son centre, servant de dispositif de fixation de la poignée L'autre extrémité du cylindre est ouverte, elle est lisse à l'intérieur et dispose à l'extérieur, de nervures rugueuses dans le sens de la rotation, sur lesquelles s'appuiera le manchon Les parties creuses entre les nervures servent à véhiculer la peinture autour du rouleau
Dans le cylindre deux fentes sont pratiquées dans le sens de la longueur, l'une en face de l'autre, sans aller aux extrémités
Elles servent à l'écoulement de la peinture vers l'extérieur,et d'épaulement aux nervures-guides des cartouches Dans le prolongement, à l'arrière, et sans percer la paroi, on trouve deux rainures-guides pour recevoir les nervures-guides de la cartouche, afin que celle-ciuisse être introduite dans le rouleau que dans une certaine position. En effet,.au-dessus des fentes et à la fin des deux rainures-guides, se trouvent deux lames capables d'ouvrir la cartouche sur toute sa longueur pendant l'introduction de celle-ci
Cette cartouche est formée par un autre cylindre d'un diamètre à peine inférieur à celui du rouleau1 arrondi à l'avant et comportant un léger collier à l'arrière, qui permet à la cartouche de tourner à l'intérieur du cylindre malgré les deux lames.The roller, according to this invention, comprises a cylinder closed with a side and provided with a threaded end perforated by its center, serving as a device for fixing the handle. The other end of the cylinder is open, it is smooth at the inside and has outside, rough ribs in the direction of rotation, on which the sleeve will rest The hollow parts between the ribs are used to convey the paint around the roller
In the cylinder two slots are made lengthwise, one opposite the other, without going to the ends
They are used for the flow of paint to the outside, and to shoulder the guide ribs of the cartridges. In the extension, at the rear, and without piercing the wall, there are two guide grooves to receive the ribs- cartridge guides, so that it can be inserted into the roller only in a certain position. Indeed, above the slots and at the end of the two guide grooves, there are two blades capable of opening the cartridge over its entire length during the introduction thereof.
This cartridge is formed by another cylinder with a diameter barely less than that of the roll 1 rounded at the front and having a slight collar at the back, which allows the cartridge to rotate inside the cylinder despite the two blades.

Elle est munie au centre d'un tube qui débute en forme d'entonnoir, son diamètre étant le même que celui de la poignée.It is provided in the center with a tube which begins in the form of a funnel, its diameter being the same as that of the handle.

ce tube est tenu par une séparation qui fait de la cartouche deux demi-cylindres. Cette séparation se prolonge vers l'xtérieur, de manière à former le long des deux côtés de la cartouche, deux nervures-guides0 A l'arrière il y a un dispositif qui permet de tourner la cartouche sur elle-mame ou de la retirer,
Le rouleau est composé en outre, d'une poignée coudée munie d'une butée après le coude, sur la partie "porteur" qui sert à retenir l'écrou de fixation de la poignée sur le cylindre, et de rendre les deux solidaires pour mettre le rouleau à l'oeuvre il suffit d'introduire dans le cylindre la cartouche, côté arrondi vers l'avant, en prenant soins que les nervures-guides soient disposées entre les rainures-guides du cylindre.En appuyant sur la cartouche celle-ci avance et prend contact avec les deux lames qui pratiquent deux ouvertures dans la cartouche qui sont disposées pour l'instant contre la paroi lisse du cylindre, ce qui empêche l'écoulement de la peinture
En tournant la cartouche légèrement vers la gauche, grâce au dispositif qui se trouve à l'arrière, les nervures-guides prennent contact avec les épaulements des fentes, et placent les ouvertures en face de celles-ci Dès cet instant, en faisant tourner le rouleau, la peinture est expulsée vers les nervures du cylindre,1 et,en-'lappuyant contre le support à peindre, le manchon s'imbibe de peinture.this tube is held by a separation which makes the cartridge two half-cylinders. This separation extends outwards, so as to form along the two sides of the cartridge, two guide ribs. At the rear there is a device which makes it possible to turn the cartridge on itself or to remove it,
The roller is further composed of a bent handle provided with a stop after the bend, on the "carrier" part which serves to retain the nut for fixing the handle on the cylinder, and to make the two integral for put the roller to work just insert the cartridge into the cylinder, rounded side forward, taking care that the guide ribs are arranged between the guide grooves of the cylinder. this advances and makes contact with the two blades which make two openings in the cartridge which are arranged for the moment against the smooth wall of the cylinder, which prevents the flow of paint
By turning the cartridge slightly to the left, thanks to the device located at the rear, the guide ribs make contact with the shoulders of the slots, and place the openings in front of them From this moment, by rotating the roller, the paint is expelled towards the ribs of the cylinder, 1 and, by pressing it against the support to be painted, the sleeve is soaked in paint.

Théoriquement lalimentation en peinture laisserait à désirer une fois la cartouche à moitié vide, mais grâce au dispositif de séparation de la cartouche, dont les ouvertures sont le prolongement, celles-ci se trouvent en roulant, successivement, à gauche si la séparation est à l'horizontale, vers le bas sielle se trouve à la verticale, Il y a donc une expultion tous les quarts de tour jusqu'à vidange complète,
Quand le manchon est alimenté en peinture, on tourne la cartouche vers la droite pour la placer en position initiale, Une fois la cartouche complètement vide, on la retire grâce au dispositif à l'arrière, et on la remplace par une pleine.Theoretically the paint supply would leave something to be desired once the cartridge is half empty, but thanks to the cartridge separation device, the openings of which are an extension, these are found rolling successively to the left if the separation is at 'horizontal, down if it is vertical, There is therefore an expultation every quarter of a turn until complete emptying,
When the sleeve is supplied with paint, the cartridge is turned to the right to place it in the initial position. Once the cartridge is completely empty, it is removed using the device at the back, and it is replaced by a full one.

L'invention est particulièrement destinée au personnel professionnel de maintenance des bStiments,( agents d'entretien, gardiens d'immeubles, bricoleurs, etc ...) qui voudraient avoir sous la main un outil prêt à l'emploi, sans être obligés de transporter et de manipuler un matériel auxiliaire. The invention is particularly intended for professional building maintenance personnel (maintenance agents, building wardens, handymen, etc.) who would like to have a ready-to-use tool on hand, without being obliged to transport and handle auxiliary equipment.

Le cylindre et les cartouches peuvent être réalisés en matière plastique moulée, à l'xception de la poignée coudée qui elle est métallique.The cylinder and the cartridges can be made of molded plastic, with the exception of the angled handle which is metallic.

Le rouleau, selon l'invention, représenté par la figure 1, est composé par un cylindre (1), fermé d'un c3té, muni d'un embout fileté, perforé au centre (2) et ouvert à l'autre extrémité (3)
L'intérieur est lisse, L'extérieur comporte des nervures (4) dans le sens de la rotation, qui constituent autant de parties en relief que creuses, Les nervures en relief sont rugueuses pour recevoir le manchon (5) et empêcher son déplacement laté ral, Les parties creuses (6) servent à véhiculer la peinture autour du rouleau, Le cylindre est pourvu de deux fentes (7), dans le sens de la longueur, placées l'une en face de l'autre, sans aller.jusqu'aux extrémités,
A l'entrée du cylindre, et jusqu'aux fentes, on trouve deux rainures-guides (8), mais qui ne transpercent pas la paroi,
Ces rainures doivent recevoir les nervures-guides (9) de la cartouche, Au-dessus des fentes, et après les rainures, se trouvent deux petites lames (10) capables d'ouvrir la cartouche en l'engageant dans le rouleau,
La cartouche (11), magasin de peinture, est formée par un autre corps cylindrique, arrondi à l'avant et comportant un collier (12) à l'arrière, La cartouche est traversée par un tube (13) par lequel passera la poignée coudée classique(17)
Lisse devant, on trouve à l'arrière une petite manette (14) en forme d'interrupteur, qui permet de la tourner sur ellemême, La manette comporte un orifice servant à retirer la cartouche vide, La cartouche est intérieurement séparée, dans le sens de la longueur, de manière à former deux demi-cylindres,
Cette séparation (15), se prolonge vers l'extérieur et forme ainsi de chaque c8té une nervure-guide (9) et c'est le long de ces nervures que seront pratiquées les ouvertures nécessaires à l'écoulement de la peinture,
En effet, il suffit de présenter la cartouche (11), face lisse en avant, à l'entrée du rouleau (3), les deux nervures 5 *) engagées dans les rainures correspondantes (8). En l'enfonçant vers l'avant elle prendra contact avec les deux lames (10) qui au fur et à mesure de l'enfoncement de la cartouche, pratiquent une fente de chaque côté de la cartouche, Ces fentes se situent pour l'instant contre la paroi lisse du cylindre, ce qui empêche l'écoulement de la peinture, Une petite rotation vers la gauche excécutée en se servant de la manette (14), met les nervures-guides en contact avec les épaulement (16) des fentes du rouleau, ce qui permet l'expulsion de la peinture
L'ensemble rouleau-cartouche est traversé par la poignée coudríft17) munie d'un écrou fileté (18) derrière une butée (19) se trouvant au-dessus du coude sur la partie "porteur". L'écrou vissé sur l'embout fileté (2) rend l'ensemble solidaire, FIG. 2 represents the device for fixing the handle,
FIG. 3 represents a diagram of the rear of the roller with the cartridge engaged, left side as seen, right side with the slot in the extension of the guide groove,
FIG. 4 represents a section of the cartridge,
FIG. 5 represents a perspective view of the cartridge,
The roller according to the invention, represented by FIG. 1, is composed of a cylinder (1), closed on one side, provided with a threaded end, perforated in the center (2) and open at the other end ( 3)
The interior is smooth, The exterior has ribs (4) in the direction of rotation, which constitute as many raised as hollow parts, The raised ribs are rough to receive the sleeve (5) and prevent its lateral movement ral, The hollow parts (6) are used to convey the paint around the roller, The cylinder is provided with two slots (7), lengthwise, placed one opposite the other, without going. 'at the extremities,
At the entrance of the cylinder, and up to the slots, there are two guide grooves (8), but which do not pierce the wall,
These grooves must receive the guide ribs (9) of the cartridge, Above the slots, and after the grooves, are two small blades (10) capable of opening the cartridge by engaging it in the roller,
The cartridge (11), paint store, is formed by another cylindrical body, rounded at the front and having a collar (12) at the rear, The cartridge is crossed by a tube (13) through which the handle will pass classic angled (17)
Smooth in front, there is a small lever (14) in the form of a switch at the rear, which allows you to turn it on itself, The lever has an opening used to remove the empty cartridge, The cartridge is internally separated, in the direction lengthwise, so as to form two half-cylinders,
This separation (15) extends outwards and thus forms on each side a guide rib (9) and it is along these ribs that the openings necessary for the flow of the paint will be made,
Indeed, it suffices to present the cartridge (11), smooth face forward, at the entrance of the roller (3), the two ribs 5 *) engaged in the corresponding grooves (8). By pushing it forward it will contact the two blades (10) which, as the cartridge is pushed in, make a slit on each side of the cartridge. These slits are located for now against the smooth wall of the cylinder, which prevents the flow of paint, A small rotation to the left executed using the handle (14), puts the guide ribs in contact with the shoulders (16) of the slots of the roller, allowing the expulsion of paint
The roller-cartridge assembly is crossed by the handle coudríft17) provided with a threaded nut (18) behind a stop (19) located above the elbow on the "carrier" part. The nut screwed onto the threaded end piece (2) makes the assembly integral,

Claims

CLAIMS 1) Paint roller reloading with disposable cartridges comprising a cylindrical body (1), closed at the front and open at the rear, into which a cartridge (11) filled with paint is introduced and which, advancing towards the front is opened automatically. The assembly is covered with a sleeve (5), provided with a bent handle (17) made integral with the roller by a nut device (18) and a threaded end (2).

2) Roller according to claim 1, characterized by a cylinder (1) having ribs (4) in the direction of rotation which form raised parts (4) to hold the sleeve, and hollow parts (6) for convey the painting.

3) Roller, according to claims 1 and 2, characterized in that the displacement is provided with a bent handle fixing device, formed by a threaded end piece (2) integral with the cylinder and a nut (18) retained by a stop (19) which allow the handle to be fixed against the cylinder

4) Roller according to claims 1, 2 and 3, characterized by two slots (7) formed in the wall of the cylinder (1) and placed one opposite the other, without touching the ends They allow the flow paint to the hollow parts (6) between the ribs (4) of the roller

5) Roller, according to claims 1 to 4, characterized by two guide grooves (8) placed at the entrance of the cylinder and joining the slots (7) without piercing the wall, one above the left slot , the other below the slot on the right. Both rigorously facing each other. Their goal being to guide the cartridge at the entry of the cylinder,

6) Roller, according to Aes claims 1 to 5, characterized in that two small steel blades (10) are located behind the groovesguides (8) at the start of the slots (7) which make it possible to make an opening in the cartridge (11) along its two guide ribs (9). These openings, thanks to their position in relation to the slots, bear strongly against the cylinder wall and block the flow of paint. Simply turn the cartridge with the handle (14) to the left, to position the opening in front of the slots so that the shoulders (76) make contact with the guide ribs of the cartridge in order to expel the paint.

LYe (

7) Roller, according to claims 1 to 6, characterized in that the cartridges (11) are provided with a separation (15), which en'fois me two half-cylinders. This device allows the total expulsion of the paint. Indeed, if its position is horizontal, the smallest mass of liquid above the partitions will necessarily flow to the left through the opening, or, in the vertical position, downwards. The effect is the same for the other half-cylinder, and therefore we have an expulsion every quarter turn

8) Roller, according to Claims 1 to 7, characterized in that the separation extends towards the outside of the cartridge, forming two guide ribs (9) serving to be received by the guide grooves (8) at the introduction of the cartridge in the cylinder.

g) Roll, according to claims 1 to 8, characterized in that the separation (is) of the cartridge, comprises in its center a conical tube at the front, going from one ends to the other, and serving to receive the carrying rod of the angled handle.
