Description

BROSSE DE BALAYAGE ET BALAI À ORGANES DE BALAYAGE INTERCALÉS OBLIQUES VERS L'EXTÉRIEUR  SCANNING BRUSH AND BROOM WITH OBLIQUE INTERLACED SCANNING BODIES OUTSIDE
L'invention concerne une brosse de balayage, et un balai doté d'une telle brosse de balayage.  The invention relates to a sweeping brush, and a broom having such a sweeping brush.
Les brosses de balayage connues (pour balais, balayettes ou brosses manuelles) comprennent généralement une tête sur laquelle est disposée une pluralité d'organes de balayage permettant de déplacer et d'accompagner les poussières et autres particules jonchant une surface à nettoyer lors du balayage. L'orientation moyenne des organes de balayage est généralement globalement perpendiculaire à une face inférieure d'empoilage de la tête de la brosse. Le mouvement de balayage s'effectue ordinairement à partir d'une position inclinée de la brosse ou du balai jusqu'à une position inclinée de la brosse ou du balai opposée à la position initiale, l'orientation des organes de balayage étant perpendiculaire à la surface à nettoyer à un instant du mouvement. Or, l'orientation variable des organes de balayage implique une efficacité du balayage variable du balayage au cours du mouvement. En effet, l'efficacité du balayage est faible lorsque les organes de balayage sont inclinés par rapport à la surface à nettoyer puis augmente au cours du mouvement jusqu'à ce que les organes de balayage soient perpendiculaires à cette surface. Ainsi l'utilisateur est amené à effectuer des mouvements de balayage rapides et répétés de faible amplitude. Un tel balayage est relativement fatiguant et augmente la durée du balayage.  The known sweeping brushes (for brushes, brushes or manual brushes) generally comprise a head on which is disposed a plurality of scanning members for moving and accompanying the dust and other particles strewing a surface to be cleaned during scanning. The average orientation of the scanning members is generally generally perpendicular to a bottom face of the brushing head of the brush. The sweeping movement is ordinarily effected from an inclined position of the brush or the brush to an inclined position of the brush or brush opposite the initial position, the orientation of the scanning members being perpendicular to the surface to clean at a moment of movement. However, the variable orientation of the scanning members implies an efficiency of the variable scanning sweep during the movement. Indeed, the scanning efficiency is low when the scanning members are inclined relative to the surface to be cleaned and increases during the movement until the scanning members are perpendicular to this surface. Thus the user is required to perform rapid and repeated scanning movements of low amplitude. Such a scan is relatively tiring and increases the duration of the scan.
L'invention vise donc à pallier ces inconvénients et à proposer un nouveau type de brosse de balayage présentant une structure permettant d'améliorer l'efficacité du nettoyage d'une surface à nettoyer, facilitant le travail de balayage et permettant d'en réduire la durée.  The invention therefore aims to overcome these drawbacks and to propose a new type of sweeping brush having a structure making it possible to improve the efficiency of the cleaning of a surface to be cleaned, facilitating the sweeping work and making it possible to reduce its duration.
L'invention vise aussi à proposer une telle brosse de balayage dont l'esthétique est améliorée.  The invention also aims at providing such a sweeping brush whose aesthetics are improved.
L'invention vise aussi à proposer une telle brosse de balayage dont la fabrication est simple, rapide, et peu coûteuse.  The invention also aims to provide such a sweeping brush whose manufacture is simple, fast, and inexpensive.
Pour ce faire, l'invention concerne une brosse de balayage comprenant une tête portant des organes de balayage allongés, chaque organe de balayage présentant une extrémité de liaison à la tête à partir de laquelle il s'étend en saillie d'une face, dite face d'empoilage, jusqu'à une extrémité libre de l'organe de balayage, les extrémités de liaison des organes de balayage étant écartées les unes des autres, For this purpose, the invention relates to a sweeping brush comprising a head carrying elongated scanning members, each sweeping having a connecting end to the head from which it extends projecting from a face, said soaking face, to a free end of the scanning member, the connecting ends of the sweeping being separated from each other,
caractérisée en ce qu'elle comprend : characterized in that it comprises:
- une première série d'organes de balayage, dits premiers organes de balayage, dont les extrémités de liaison sont agencées sur la face d'empoilage selon au moins une courbe, dite première courbe d'empoilage, de la face d'empoilage,  a first series of scanning members, called first scanning members, whose connection ends are arranged on the stacking face according to at least one curve, called the first stacking curve, of the stacking face;
- une deuxième série d'organes de balayage, dits organes obliques de balayage, agencés de sorte que :  a second series of scanning members, said oblique scanning members, arranged so that:
o chaque organe oblique de balayage s'étend à partir de ladite face d'empoilage en passant entre deux premiers organes de balayage adjacents sur la première courbe d'empoilage,  each oblique scanning member extends from said empoiling face by passing between two first adjacent scanning members on the first stacking curve,
o l'extrémité de liaison de chaque organe oblique de balayage est située sur la face d'empoilage d'un premier côté, dit côté intérieur, de la première courbe d'empoilage,  o the connecting end of each oblique scanning member is located on the face of empoilage of a first side, said inner side, of the first stacking curve,
o l'extrémité libre de chaque organe oblique de balayage est située d'un autre côté, dit côté extérieur, de la première courbe d'empoilage,  o the free end of each oblique scanning member is located on the other side, said outer side, of the first stacking curve,
o ledit côté extérieur est plus à l'extérieur de la tête que ledit côté intérieur.  o said outer side is more outside of the head than said inner side.
Ainsi, chaque organe oblique de balayage est intercalé entre deux premiers organes de balayage adjacents, plus incliné vers l'extérieur que ces derniers, et les premiers organes de balayage et les organes obliques de balayage s'entrecroisent. Les inventeurs ont déterminé que le simple fait d'entrecroiser ces différents organes de balayage permet non seulement d'augmenter la surface efficace de balayage de la brosse, mais également d'améliorer l'accompagnement des particules jonchant une surface sale dans toute la plage d'inclinaison angulaire de la brosse de balayage par rapport à la surface à nettoyer, et ainsi de faciliter et d'accélérer le nettoyage. En effet, lorsque le balai est incliné par rapport à la surface à nettoyer, les organes obliques de balayage plus inclinés vers l'extérieur de la tête de la brosse sont au contact de la surface à nettoyer avec une orientation optimale par rapport à cette dernière. Ainsi, une brosse de balayage selon l'invention permet d'obtenir une orientation des organes de balayage par rapport à la surface à nettoyer optimale tout au long du mouvement de balayage. Une personne balayant une surface sale pourra ainsi diminuer le nombre de mouvements de balayage en augmentant l'amplitude du mouvement de balayage et donc en réduisant la durée de balayage de la surface sale. De plus, l'entrecroisement des organes de balayage apporte à la brosse une esthétique particulière, distinctive et particulièrement avantageuse. Thus, each oblique scanning member is interposed between two first adjacent scanning members, more outwardly inclined than the latter, and the first scanning members and the oblique scanning members intersect each other. The inventors have determined that the simple fact of intercrossing these different scanning members not only increases the effective sweeping surface of the brush, but also improves the accompaniment of particles strewn with a dirty surface throughout the entire range. angular inclination of the sweeping brush with respect to the surface to be cleaned, and thus to facilitate and speed up the cleaning. Indeed, when the blade is inclined relative to the surface to be cleaned, the oblique scanning bodies more inclined towards the outside of the brush head are in contact with the surface to be cleaned with an optimal orientation compared to the latter. Thus, a sweeping brush according to the invention makes it possible to obtain an orientation of the scanning members with respect to the surface to be cleaned optimally throughout the scanning movement. A person sweeping a dirty surface can thus reduce the number of scanning movements by increasing the amplitude of the scanning movement and thus reducing the sweeping time of the dirty surface. In addition, the interlacing of the scanning members provides the brush with a particular, distinctive and particularly advantageous aesthetic.
L'invention s'applique à une brosse de balayage dont chaque première courbe d'empoilage présente une forme quelconque, et à une brosse de balayage pouvant présenter plusieurs premières courbes d'empoilage, par exemple juxtaposées les unes aux autres s'étendant globalement dans la longueur de la brosse de balayage dont la tête est allongée. Une brosse de balayage selon l'invention peut comporter une seule série d'organes obliques de balayage intercalés entre les premiers organes de balayage agencés selon une même première courbe d'empoilage, ou au contraire plusieurs séries d'organes obliques de balayage intercalés entre les premiers organes de balayage agencés selon plusieurs premières courbes d'empoilage.  The invention applies to a sweeping brush with each first stacking curve having any shape, and to a sweeping brush having a plurality of first stacking curves, for example juxtaposed with one another extending generally in the length of the sweeping brush whose head is elongated. A sweeping brush according to the invention may comprise a single series of oblique scanning members interposed between the first scanning members arranged according to the same first stacking curve, or on the contrary several series of oblique scanning organs interposed between first scanning members arranged according to a plurality of first stacking curves.
Cela étant, avantageusement et selon l'invention, une première courbe d'empoilage est une courbe fermée. Plus particulièrement, une première courbe d'empoilage est une courbe périphérique de la tête de la brosse.  That being so, advantageously and according to the invention, a first stacking curve is a closed curve. More particularly, a first stacking curve is a peripheral curve of the brush head.
Dans certains modes de réalisation préférentiels, avantageusement et selon l'invention, la brosse comporte une unique série d'organes obliques de balayage intercalés entre les premiers organes de balayage agencés selon une première courbe d'empoilage fermée périphérique de la tête. Dans ces modes de réalisation, avantageusement et selon l'invention, les extrémités de liaison des organes obliques de balayage sont agencées selon une deuxième courbe fermée d'empoilage inscrite dans ladite première courbe d'empoilage. Une telle disposition des organes de balayage permet d'optimiser la surface de balayage. Néanmoins, rien n'empêche en variante de prévoir une première courbe d'empoilage non fermée et une deuxième courbe d'empoilage non fermée juxtaposée à la première courbe d'empoilage, les différents organes de balayage s 'entrecroisant. In certain preferred embodiments, advantageously and according to the invention, the brush comprises a single series of oblique scanning members interposed between the first scanning members arranged in a first closed peripheral encasing curve of the head. In these embodiments, advantageously and according to the invention, the connecting ends of the oblique scanning members are arranged in a second closed stacking curve inscribed in said first stacking curve. Such an arrangement of the scanning members optimizes the scanning surface. Nevertheless, nothing prevents alternatively to provide a first unclosed stacking curve and a second unclosed stacking curve juxtaposed with the first stacking curve, the different scanning members intercrossing.
L'invention s'applique à toutes sortes d'organes de balayage. Dans certains modes de réalisation, avantageusement et selon l'invention, chaque organe de balayage est choisi dans le groupe formé des poils, des faisceaux (touffes) de poils, des lamelles, des groupements de lamelles. Lorsqu'un organe de balayage est constitué d'une pluralité d'éléments juxtaposés (poils ou lamelles) ces différents éléments juxtaposés sont fixés à la face d'empoilage par une même extrémité de liaison, et forment ainsi un seul et même organe de balayage. Par exemple, un organe de balayage peut être un seul poil ou un groupement de poils naturels (filaments, fibres végétales) ou bien synthétiques (élastomères, mousses, fils métalliques,...), chaque poil pouvant être fleuré, ondulé ou droit. Lorsqu'un organe de balayage est composé d'une pluralité d'éléments juxtaposés, la longueur de ces différents éléments juxtaposés à partir de l'extrémité de liaison peut être la même ou non, selon la forme que l'on veut donner à l'extrémité libre de balayage de l'organe de balayage.  The invention applies to all kinds of scanning members. In some embodiments, advantageously and according to the invention, each scanning member is selected from the group consisting of bristles, bundles (tufts) of bristles, lamellae, groups of lamellae. When a scanning member consists of a plurality of juxtaposed elements (bristles or lamellae) these juxtaposed elements are attached to the facing face by the same connecting end, and thus form a single scanning member . For example, a scanning member may be a single pile or a group of natural bristles (filaments, plant fibers) or synthetic (elastomers, foams, wire, ...), each hair may be flush, corrugated or straight. When a scanning member is composed of a plurality of juxtaposed elements, the length of these different elements juxtaposed from the connecting end may be the same or not, depending on the shape that we want to give to the free end of scanning of the scanning member.
Les premiers organes de balayage peuvent présenter une longueur maximum à partir de leur extrémité de liaison qui peut être différente d'un premier organe de balayage à l'autre le long de la première courbe d'empoilage, par exemple de façon à former des ondulations. Cela étant, dans certains modes de réalisation, avantageusement et selon l'invention, les premiers organes de balayage présentent tous une même longueur maximum.  The first scanning members may have a maximum length from their connecting end which may be different from a first scanning member to another along the first stacking curve, for example to form corrugations. . However, in some embodiments, advantageously and according to the invention, the first scanning members all have the same maximum length.
De même, les organes obliques de balayage peuvent présenter une longueur maximum à partir de leur extrémité de liaison qui peut être différente d'un organe oblique de balayage à l'autre le long de la deuxième courbe d'empoilage, par exemple de façon à former des ondulations. Cela étant, dans certains modes de réalisation, avantageusement et selon l'invention, les organes obliques de balayage présentent une même longueur maximum. Plus particulièrement, dans certains modes de réalisation avantageux, le rapport entre la longueur maximum des premiers organes de balayage et la longueur maximum des organes obliques de balayage est comprise entre 0,7 et 1,2, par exemple de l'ordre de 1, plus particulièrement 1,1. Similarly, the oblique scanning members may have a maximum length from their connecting end which may be different from one oblique scanning member to another along the second stacking curve, for example so as to to form undulations. However, in some embodiments, advantageously and according to the invention, the oblique scanning members have the same maximum length. More particularly, in certain advantageous embodiments, the ratio between the maximum length of the first scanning members and the maximum length of the oblique scanning organs is between 0.7 and 1.2, for example of the order of 1, more particularly 1.1.
En outre, la forme de l'extrémité libre des premiers organes de balayage et des organes obliques de balayage peut être quelconque, variable d'un premier organe de balayage à l'autre et/ou d'un organe oblique de balayage à l'autre, ou identique pour tous les premiers organes de balayage et/ou pour tous les organes obliques de balayage.  In addition, the shape of the free end of the first scanning members and the oblique scanning members may be arbitrary, variable from one first scanning member to another and / or from an oblique scanning member to the other, or the same for all first scanning members and / or for all oblique scan members.
La tête d'une brosse de balayage selon l'invention peut être réalisée dans de nombreuses variantes différentes, en particulier en une seule ou plusieurs pièce(s) issue(s) de moulage ou par impression 3D.  The head of a sweeping brush according to the invention can be made in many different variants, in particular in one or more part (s) issued (s) molding or 3D printing.
Dans certains modes de réalisation avantageux et selon l'invention, la tête comprend :  In certain advantageous embodiments and according to the invention, the head comprises:
- une première monture sur laquelle sont assemblés les premiers organes de balayage,  a first frame on which the first scanning members are assembled,
- une deuxième monture sur laquelle sont assemblés les organes obliques de balayage,  a second frame on which the oblique scanning members are assembled,
la première monture et la deuxième monture étant assemblées l'une à l'autre rigidement. the first frame and the second frame being joined to each other rigidly.
Ainsi, la brosse est particulièrement simple, rapide et peu coûteuse à fabriquer. En effet, il est alors facile d'intercaler les différents organes de balayage par simple encastrement de la deuxième monture dans la première monture avec ou sans l'aide de gabarit d'assemblage, tout en minimisant la distance entre les organes de balayage adjacents de chaque monture lors de l'assemblage des organes de balayage. En outre, le fait d'assembler les organes de balayages sur des montures séparées permet de modifier simplement des paramètres de fabrication tels que la hauteur de coupe des organes de balayages et leur densité déterminée par la quantité de poils ou de lamelles par organe de balayage et de leur épaisseur.  Thus, the brush is particularly simple, fast and inexpensive to manufacture. Indeed, it is then easy to insert the different scanning members by simply embedding the second frame in the first frame with or without the help of jig assembly, while minimizing the distance between the adjacent scanning members of each mount when assembling the scanning members. In addition, the fact of assembling the scoring members on separate frames makes it possible to simply modify manufacturing parameters such as the cutting height of the scanning members and their density determined by the amount of bristles or lamellae per scanning member. and their thickness.
Dans certains modes de réalisation avantageusement, la première monture est formée d'une pièce présentant un logement d'encastrement de la deuxième monture à l'intérieur de la première courbe d'empoilage fermée périphérique de la première monture. L'assemblage des deux montures peut donc être effectué simplement en encastrant la deuxième monture dans le logement d'encastrement à l'intérieur d'un espace délimité par les premiers organes de balayage s 'étendant à partir de la première courbe d'empoilage fermée périphérique de la première monture. De préférence, la forme et les dimensions de la deuxième monture correspondent exactement à celles du logement d'encastrement présenté par la première monture. In certain embodiments, the first frame is advantageously formed of a piece having a recess housing of the second frame inside the first peripheral closed encasing curve of the first frame. The assembly of the two frames can therefore be performed simply by embedding the second frame in the recess housing within a space defined by the first scanning members extending from the first peripheral closed potting curve of the first frame. Preferably, the shape and dimensions of the second frame correspond exactly to those of the recess housing presented by the first frame.
En outre, l'assemblage rigide de la première monture et de la deuxième monture peut au moins pour partie résulter des formes et dimensions conjuguées du logement d'encastrement et de la deuxième monture, qui peuvent en particulier être adaptées pour former un assemblage par serrage et/ou engagement à force avec contrainte élastique résiduelle de serrage. En variante ou en combinaison, l'assemblage rigide de la première monture et la deuxième monture est au moins pour partie avantageusement réalisé par des organes d'assemblage rapide sans outil, de préférence à verrouillage élastique, réversible ou irréversible, par exemple avec au moins un crochet, bossage, nervure de l'une des montures s'insérant dans un évidement conjugué de verrouillage de l'autre monture.  In addition, the rigid assembly of the first frame and the second frame can at least partially result in the combined shapes and dimensions of the recess housing and the second frame, which can in particular be adapted to form a clamping assembly. and / or force engagement with residual elastic clamping stress. As a variant or in combination, the rigid assembly of the first frame and the second frame is at least partly advantageously achieved by means of quick assembly members without tools, preferably with elastic locking, reversible or irreversible, for example with at least a hook, boss, rib of one of the mounts fit into a recess locking recess of the other mount.
Dans certains modes de réalisation, avantageusement et selon l'invention, la deuxième monture présente une face d'empoilage bombée présentant un pourtour incliné, et les extrémités de liaison des organes obliques de balayage sont assemblées le long de ce pourtour incliné. De préférence, les organes obliques de balayage sont assemblés au pourtour incliné de telle sorte que chaque organe oblique de balayage s'étend selon une direction moyenne de l'organe oblique de balayage, dite direction oblique, orientée au moins sensiblement selon une normale au pourtour incliné. Plus particulièrement, les extrémités de liaison des organes obliques de balayage sont fixées dans des trous borgnes de la face d'empoilage présentant une direction principale déterminant la direction moyenne des organes obliques de balayage, et cette direction principale est orientée au moins sensiblement selon une normale au pourtour incliné. Ainsi, l'inclinaison des organes obliques de balayage est déterminée par l'inclinaison du pourtour incliné et par la direction principale des trous recevant leur extrémité de liaison. Par ailleurs, rien n'empêche dans certains modes de réalisation de prévoir que d'autres organes de balayage soient assemblés à la deuxième monture sur une portion de surface interne de la face d'empoilage délimitée par la deuxième courbe d'empoilage. Ces organes de balayage peuvent être similaires audits premiers organes de balayage ou audits organes obliques de balayage, ou bien différents. In some embodiments, advantageously and according to the invention, the second frame has a convex side facing with an inclined periphery, and the connecting ends of the oblique scanning members are assembled along this inclined periphery. Preferably, the oblique scanning members are assembled at the inclined periphery so that each oblique scanning member extends in a mean direction of the oblique scanning member, said oblique direction, oriented at least substantially according to a normal around the circumference inclined. More particularly, the connecting ends of the oblique scanning members are fixed in blind holes of the stacking face having a main direction determining the mean direction of the oblique scanning members, and this main direction is oriented at least substantially according to a normal at the inclined periphery. Thus, the inclination of the oblique scanning members is determined by the inclination of the inclined periphery and the main direction of the holes receiving their connecting end. Moreover, nothing prevents certain embodiments from providing that other scanning members are assembled to the second frame on an inner surface portion of the stacking face delimited by the second stacking curve. These scanning devices may be similar to the first scanners or oblique scanning organs, or different.
De préférence, la tête de la brosse comprend un manchon (fixe ou articulé) adapté pour pouvoir être assemblé à un manche à balai. Ainsi, une brosse selon l'invention peut être facilement assemblée à un manche à balai et/ou remplacer une brosse amovible de balai.  Preferably, the head of the brush comprises a sleeve (fixed or articulated) adapted to be assembled to a joystick. Thus, a brush according to the invention can be easily assembled to a broom handle and / or replace a removable broom brush.
L'invention s'étend également à un balai ou à une balayette comprenant une brosse selon l'invention.  The invention also extends to a broom or a brush comprising a brush according to the invention.
L'invention concerne également une brosse de balayage et un balai caractérisés en combinaison par tout ou partie des caractéristiques mentionnées ci-dessus ou ci-après.  The invention also relates to a sweeping brush and a brush characterized in combination by all or some of the characteristics mentioned above or below.

Une brosse de balayage selon un premier mode de réalisation de l'invention est représentée sur les figures 1 à 5. La brosse de balayage comprend une tête 20 portant une pluralité d'organes de balayage.  A sweeping brush according to a first embodiment of the invention is shown in Figures 1 to 5. The sweeping brush comprises a head 20 carrying a plurality of scanning members.
La tête 20 comprend une première monture 27 globalement rectangulaire s 'étendant longitudinalement selon un axe, dit axe longitudinal jusqu'à deux extrémités longitudinales. La première monture 27 présente une face 33 inférieure orientée vers le sol lors du balayage, présentant un renfoncement 49 délimité par un rebord 50 périphérique formé par un épaulement périphérique de la première monture. La première monture 27 peut être issue de moulage, constituée d'un matériau synthétique polymérique, de bois, ou autre. Une première série d'organes de balayage, dits premiers organes de balayage, est assemblée sur une face 41 inférieure d'empoilage du rebord périphérique de la première monture 27 selon une courbe fermée d'empoilage, dite première courbe 37 d'empoilage.  The head 20 comprises a first generally rectangular frame 27 extending longitudinally along an axis, said longitudinal axis up to two longitudinal ends. The first mount 27 has a lower face 33 oriented towards the ground during scanning, having a recess 49 defined by a peripheral rim 50 formed by a peripheral shoulder of the first frame. The first frame 27 may be derived from molding, consisting of a polymeric synthetic material, wood, or other. A first series of scanning members, said first scanning members, is assembled on a lower face 41 of empoilage of the peripheral rim of the first frame 27 in a closed curve of empoiling, said first curve 37 of stacking.
La tête 20 de la brosse de balayage comprend également une deuxième monture 28. La deuxième monture 28 peut être issue de moulage, constituée d'un matériau synthétique polymérique, de bois, ou autre. Cette deuxième monture 28 présente des formes et dimensions conjuguées de celles du renfoncement de la face 33 inférieure de la première monture 27, de sorte que ce renfoncement constitue un logement d'encastrement de la deuxième monture 28. La deuxième monture 28 présente en particulier une face supérieure au moins sensiblement plane, dite face 34 supérieure, venant contre le fond 33 du renfoncement de la première monture 27 lorsque la deuxième monture 28 est encastrée dans le renfoncement de la première monture 27.  The head 20 of the sweeping brush also comprises a second frame 28. The second frame 28 may be derived from molding, consisting of a polymeric synthetic material, wood, or other. This second mount 28 has shapes and dimensions conjugate with those of the recess of the lower face 33 of the first mount 27, so that this recess constitutes a recess housing of the second mount 28. The second mount 28 has in particular a at least substantially flat upper surface, said upper face 34, coming against the bottom 33 of the recess of the first mount 27 when the second mount 28 is embedded in the recess of the first mount 27.
La deuxième monture 28 comprend également une face 29 inférieure d'empoilage bombée opposée à la face 34 supérieure plane et orientée vers la surface à nettoyer lors du balayage. L'épaisseur de la deuxième monture 28 est supérieure à la hauteur du rebord périphérique, de sorte que la face 29 inférieure bombée est en saillie par rapport au rebord périphérique de la première monture 27. Une deuxième série d'organes de balayage, dits organes 23 obliques de balayage, est assemblée sur la deuxième monture 28. The second mount 28 also includes a lower face 29 of bulging stocking opposite to the flat upper face 34 and facing the surface to be cleaned during scanning. The thickness of the second mount 28 is greater than the height of the peripheral rim, so that the convex lower face 29 is projecting from the peripheral rim of the first mount 27. A second series of scanning members, said oblique scanning members 23, is assembled on the second mount 28.
Afin de verrouiller la deuxième monture 28 encastrée dans la première monture 27 :  In order to lock the second mount 28 recessed in the first mount 27:
- la première monture 27 comprend une fenêtre 47 au niveau de chaque extrémité longitudinale de la première monture 27, chaque fenêtre 47 comprenant un épaulement 31 de verrouillage orienté vers le centre de la première monture 27, - la face 34 supérieure plane de la deuxième monture 28 porte des crochets 32 élastiques de verrouillage s'étendant en saillie de chaque extrémité longitudinale de la face 34 supérieure plane, chaque crochet 32 pouvant être inséré dans une fenêtre 47 de la première monture 27 et coopérant avec l'épaulement 31 de verrouillage de cette dernière pour verrouiller en place la deuxième monture 28 dans le renfoncement de la première monture 27. the first mount 27 comprises a window 47 at each longitudinal end of the first mount 27, each window 47 comprising a shoulder 31 of locking oriented towards the center of the first mount 27, the flat upper face 34 of the second mount 28 carries locking elastic hooks 32 protruding from each longitudinal end of the plane top face 34, each hook 32 being insertable in a window 47 of the first mount 27 and cooperating with the locking shoulder 31 of this last to lock in place the second mount 28 in the recess of the first mount 27.
Les crochets 32 de verrouillage sont ainsi adaptés pour être insérés en force et pliés élastiquement en flexion dans les fenêtres 47 de la première monture 27 lors de l'encastrement. Après encastrement de la deuxième monture dans la première monture, chaque crochet 32 est alors en butée contre l'épaulement 31 de maintien de la fenêtre 47 en regard de cet organe 32 d'assemblage. Ainsi, les deux montures sont assemblées et fixées rigidement entre elles.  The locking hooks 32 are thus adapted to be inserted into force and bent elastically in bending in the windows 47 of the first frame 27 during embedding. After embedding the second mount in the first mount, each hook 32 is then in abutment against the shoulder 31 for holding the window 47 opposite this assembly member 32. Thus, the two frames are assembled and fixed rigidly between them.
Dans les modes de réalisation représentés, les deux montures sont maintenues ensemble par verrouillage élastique résultant de l'assemblage. En variante ou en combinaison, rien n'empêche d'assembler rigidement les deux montures l'une à l'autre par d'autres modes d'assemblage, par exemple par collage et/ou soudure. L'assemblage rigide peut-être réversible pour permettre un démontage ultérieur, ou au contraire irréversible, les deux montures ne pouvant pas être démontées sans cassure.  In the embodiments shown, the two frames are held together by elastic locking resulting from the assembly. As a variant or in combination, nothing prevents the two mounts to be rigidly joined to one another by other assembly methods, for example by gluing and / or welding. The rigid assembly may be reversible to allow subsequent disassembly, or otherwise irreversible, the two frames can not be disassembled without breaking.
La face 21 d'empoilage de la tête 20 de la brosse est formée par le rebord périphérique de la première monture 27 et par la face 29 inférieure d'empoilage bombée de la deuxième monture 28.  The facing face 21 of the head 20 of the brush is formed by the peripheral rim of the first mount 27 and by the lower face 29 of convex encasement of the second mount 28.
Chaque premier organe 22 de balayage de la première série d'organe de balayage s'étend à partir d'une extrémité 43 de liaison audit rebord périphérique jusqu'à une extrémité 44 libre du premier organe 22 de balayage. Chaque premier organe 22 de balayage s'étend selon une direction moyenne, dite première direction 24. Lorsque le premier organe de balayage est formé d'un unique poil ou d'une unique lamelle, cette première direction est la direction longitudinale du poil ou de la lamelle. Lorsque le premier organe de balayage est formé d'une touffe de poils ou d'un groupement de lamelles, la première direction est la direction moyenne de la touffe de poils ou du groupement de lamelles. Each first scanning member 22 of the first scan unit series extends from a connecting end 43 to said flange peripheral to a free end 44 of the first scanning member 22. Each first scanning member 22 extends in a mean direction, said first direction 24. When the first scanning member is formed of a single pile or a single strip, this first direction is the longitudinal direction of the pile or of the coverslip. When the first scanning member is formed of a tuft of bristles or a group of lamellae, the first direction is the average direction of the tuft of bristles or group of lamellae.
Cette première direction forme un premier angle a par rapport à une génératrice 25 d'une surface 35 théorique cylindrique (au sens mathématique du terme selon lequel une surface cylindrique de l'espace est une surface engendrée par le déplacement d'une droite génératrice sur une courbe de base quelconque) dont la première courbe 37 d'empoilage est une courbe de base, la première direction étant inclinée vers l'extérieur d'un espace 40 fermé délimité par la surface 35 cylindrique théorique. L'angle a est supérieur ou égal à zéro.  This first direction forms a first angle α with respect to a generatrix 25 of a theoretical cylindrical surface (in the mathematical sense of the term according to which a cylindrical surface of the space is a surface generated by the displacement of a generating line on a any base curve) of which the first stacking curve 37 is a base curve, the first direction being inclined outwardly of a closed space 40 delimited by the theoretical cylindrical surface. The angle a is greater than or equal to zero.
La deuxième série d'organes de balayage, dits organes 23 obliques de balayage, est assemblée à la deuxième monture 28 de sorte que, après assemblage de la deuxième monture 28 avec la première monture 27 :  The second series of scanning members, said oblique scanning members 23, is assembled to the second mount 28 so that, after assembly of the second mount 28 with the first mount 27:
- l'extrémité 43 de liaison de chaque organe 23 oblique de balayage est située sur la face 29 inférieure bombée et donc à l'intérieur dudit espace 40 fermé et sur une normale 39 à la première courbe 37 d'empoilage,  the connecting end 43 of each oblique scanning member 23 is located on the convex lower face 29 and thus inside said closed space 40 and on a normal 39 at the first stacking curve 37,
- chaque organe 23 oblique de balayage s'étend à partir de ladite face 29 inférieure bombée selon une direction moyenne de l'organe 23 oblique de balayage, dite direction oblique 26, formant, par rapport à la génératrice 25, un deuxième angle β d'inclinaison vers l'extérieur de la surface 35 cylindrique théorique, ce deuxième angle β étant supérieur audit premier angle a d'inclinaison,  each oblique scanning member 23 extends from said convex lower face 29 in a mean direction of the oblique scanning member 23, said oblique direction 26, forming, with respect to the generator 25, a second angle β d outward inclination of the theoretical cylindrical surface, this second angle β being greater than said first angle of inclination,
- l'extrémité 44 libre de chaque organe 23 oblique de balayage est située plus à l'extérieur de ladite surface 35 cylindrique théorique que les extrémités 44 libres desdits deux premiers organes 22 de balayage adjacents,  the free end 44 of each oblique scanning member 23 is located further outside said theoretical cylindrical surface than the free ends 44 of said two adjacent first scanning members 22,
- chaque organe 23 oblique de balayage passe entre deux premiers organes 22 de balayage adjacents situés sur la première courbe 37 d'empoilage. La deuxième série d'organe est ainsi assemblée sur la face 29 inférieure bombée de la deuxième monture 28 selon une courbe fermée d'empoilage, dite deuxième courbe 38 d'empoilage. each oblique scanning member 23 passes between two first adjacent scanning members 22 situated on the first stacking curve 37. The second series of members is thus assembled on the convex lower face 29 of the second frame 28 in a closed stacking curve, called the second stacking curve 38.
Dans certains modes de réalisation avantageux, chaque angle a est compris entre 0° et 20° plus particulièrement entre 0° et 15°, plus particulièrement entre 0° et 10°, plus particulièrement entre 0° et 5°, plus particulièrement de l'ordre de 0°. En outre, avantageusement et selon l'invention, chaque angle β est compris entre 20°et 120°, plus particulièrement entre 20° et 90°, plus particulièrement entre 20° et 45°, plus particulièrement de l'ordre de 30°.  In certain advantageous embodiments, each angle a is between 0 ° and 20 ° more particularly between 0 ° and 15 °, more particularly between 0 ° and 10 °, more particularly between 0 ° and 5 °, more particularly between order of 0 °. In addition, advantageously and according to the invention, each angle β is between 20 ° and 120 °, more particularly between 20 ° and 90 °, more particularly between 20 ° and 45 °, more particularly of the order of 30 °.
L'angle a peut varier d'un premier organe de balayage à l'autre. De préférence, dans certains modes de réalisation avantageux, l'angle a est le même pour tous les premiers organes de balayage.  The angle α may vary from one scanning organ to another. Preferably, in certain advantageous embodiments, the angle α is the same for all the first scanning members.
De même, l'angle β peut varier d'un organe oblique de balayage à l'autre. De préférence, dans certains modes de réalisation avantageux, l'angle β est le même pour tous les organes obliques de balayage.  Likewise, the angle β can vary from one oblique scanning organ to another. Preferably, in certain advantageous embodiments, the angle β is the same for all oblique scanning devices.
Les organes de balayage peuvent être quelconques, et notamment être choisis dans le groupe constitué des poils naturels (filaments, fibres végétales), synthétiques (élastomères, mousse, fils métalliques), des poils fleurés, des poils ondulés et des poils droits.  The scanning members may be any, and in particular be selected from the group consisting of natural bristles (filaments, plant fibers), synthetic (elastomers, foam, metal threads), flowering hairs, wavy hairs and straight hairs.
Les premiers organes de balayage et les organes obliques de balayage peuvent être de nature et/ou d'épaisseur et/ou de longueur et/ou différentes.  The first scanning members and the oblique scanning members may be of nature and / or of thickness and / or of length and / or different.
Le rebord périphérique et la face 29 inférieure bombée comprennent une pluralité de trous 42 borgnes, de préférence à section droite transversale circulaire, dans lesquels sont fixés les organes de balayage. Les trous 42 borgnes placés sur une même courbe d'empoilage 37, 38 sont espacés, par exemple, d'une distance de l'ordre de 24mm entre eux, plus particulièrement de l'ordre de 17mm. Néanmoins, rien n'empêche d'avoir des trous 42 borgnes espacés entre eux, sur une même courbe d'empoilage 37, 38, d'une distance variable. Les trous 42 borgnes de la deuxième monture 28 sont décalés par rapport aux trous 42 borgnes de la première monture 27 afin qu'un organe oblique 23 de balayage soit interposé entre deux premiers organes de balayage. Les trous 42 borgnes de la deuxième monture 28 sont placés sur un pourtour 45 incliné délimitant la face 29 inférieure bombée. Les trous 42 borgnes présentent une direction principale au moins sensiblement égale à la direction moyenne des organes obliques de balayage et déterminant l'angle β. Avantageusement, le pourtour 45 incliné est aussi incliné de telle sorte que la direction principale des trous 42 borgnes soit au moins sensiblement normal au pourtour 45 incliné. The peripheral rim and the curved lower face 29 comprise a plurality of blind holes 42, preferably of circular cross section, in which the scanning members are fixed. The blind holes 42 placed on the same stacking curve 37, 38 are spaced, for example, a distance of about 24mm between them, more particularly of the order of 17mm. Nevertheless, nothing prevents having blind holes 42 spaced apart from each other, on the same stacking curve 37, 38, of a variable distance. The blind holes 42 of the second mount 28 are offset relative to the blind holes 42 of the first mount 27 so that an oblique member 23 scanning is interposed between two first scanning members. The blind holes 42 of the second frame 28 are placed on an inclined periphery 45 delimiting the curved lower face 29. The blind holes 42 have a main direction at least substantially equal to the mean direction of the oblique scanning members and determining the angle β. Advantageously, the inclined periphery 45 is also inclined so that the principal direction of the blind holes 42 is at least substantially normal to the inclined periphery 45.
Chaque organe de balayage comprend par exemple une pluralité de poils repliés sur eux, le repliement formant une extrémité 43 de liaison de l'organe de balayage. Avantageusement, l'extrémité 43 de liaison de chaque organe de balayage est fixée dans un trou borgne par une agrafe enfoncée dans le trou 42 borgne et maintenant l'extrémité 43 de liaison de l'organe de balayage au fond du trou 42 borgne au niveau de son repliement.  Each scanning member comprises for example a plurality of bristles folded over them, the folding forming a connecting end 43 of the scanning member. Advantageously, the connecting end 43 of each scanning member is fixed in a blind hole by a staple driven into the blind hole 42 and maintaining the connecting end 43 of the scanning member at the bottom of the hole 42 blind at its folding.
La face 29 inférieure bombée étant en saillie, les organes obliques de balayage ne sont pas en contact avec la première monture 27.  The convex lower face 29 being projecting, the oblique scanning members are not in contact with the first frame 27.
La direction d'une projection d'un organe oblique 23 de balayage sur un plan, comprenant la première direction 24 d'un premier organe 22 de balayage et étant parallèle à la direction oblique 26 d'un organe oblique 23 de balayage, croise la première direction 24 du premier organe 22 de balayage au niveau d'un point, dit point 48 de croisement. La position de ce point de croisement dépend de l'angle des organes obliques de balayage et de la distance entre la première courbe 37 d'empoilage et la deuxième courbe 38 d'empoilage.  The direction of a projection of an oblique member 23 scanning on a plane, comprising the first direction 24 of a first member 22 of scanning and being parallel to the oblique direction 26 of an oblique member 23 scanning, crosses the first direction 24 of the first scanning member 22 at a point, said point 48 crossing. The position of this crossing point depends on the angle of the oblique scanning members and the distance between the first stacking curve 37 and the second stacking curve 38.
Le fait d'interposer un organe oblique 23 de balayage entre deux premiers organes de balayage permet de combler les vides et d'augmenter la surface de balayage en largeur sur l'ensemble de la tête de la brosse. De plus, lorsqu'un balai comprenant une telle brosse est incliné, la direction oblique 26 est sensiblement perpendiculaire au sol augmentant ainsi la surface efficace de balayage permettant d'obtenir une efficacité de balayage optimale dans toutes les situations, par exemple lors du balayage d'une surface située sous du mobilier.  The fact of interposing an oblique scanning member 23 between two first scanning members makes it possible to fill the voids and to increase the sweeping area in width over the entire head of the brush. In addition, when a broom comprising such a brush is inclined, the oblique direction 26 is substantially perpendicular to the ground thus increasing the effective scanning surface to obtain an optimal scanning efficiency in all situations, for example during the scanning. 'an area under furniture.
Ainsi, avantageusement, dans le premier mode de réalisation représenté à la figure 1, les organes de balayage assemblés au pourtour 45 incliné sont tous des organes obliques de balayage. Néanmoins, rien n'empêche qu'une partie des organes de balayage assemblés au pourtour 45 incliné de la deuxième monture 28 soient des organes obliques de balayage et qu'une autre partie soient des premiers organes de balayage tel que représenté à la figure 7. Thus, advantageously, in the first embodiment shown in FIG. 1, the scanning members assembled at the inclined periphery 45 are all oblique scanning organs. Nevertheless, nothing prevents a part of the scanning members assembled at the inclined periphery 45 of the second frame 28 are oblique scanning members and another part are first scanning members as shown in Figure 7.
La face 29 inférieure bombée de la deuxième monture 28 comprend également des trous 42 borgnes représentés, sur une surface 46 délimitée par le pourtour 45 incliné, avec lesquels sont assemblés des premiers organes de balayage.  The convex lower face 29 of the second frame 28 also comprises blind holes 42 shown on a surface 46 defined by the inclined periphery 45, with which first scanning members are assembled.
En outre, la brosse comprend également un manchon 30 d'assemblage à un manche de balai. Le manchon 30 peut être articulé au centre de la première monture 27 selon un axe de rotation orthogonale à la direction longitudinale de la tête.  In addition, the brush also includes a coupling sleeve 30 to a broom handle. The sleeve 30 may be articulated in the center of the first frame 27 along an axis of rotation orthogonal to the longitudinal direction of the head.
L'invention peut faire l'objet de nombreuses variantes de réalisation par rapport aux modes de réalisation décrits ci-dessus et représentés sur les figures. En particulier, la brosse peut comprendre des organes obliques de balayage sur la première courbe d'empoilage.  The invention may be the subject of numerous variants with respect to the embodiments described above and shown in the figures. In particular, the brush may comprise oblique scanning members on the first stacking curve.
Une brosse selon l'invention peut être utilisée pour former un balai (comprenant un manche assemblé à une brosse selon l'invention) une balayette ou autre. La disposition, la forme, la nature, le nombre des différents organes de balayage d'une brosse selon l'invention peuvent faire l'objet de très nombreuses variantes autres que celles représentées et décrites ci-dessus.  A brush according to the invention can be used to form a brush (comprising a handle assembled with a brush according to the invention) a brush or other. The arrangement, the shape, the nature, the number of different scanning members of a brush according to the invention can be subject to many variations other than those shown and described above.
