Abstract

The invention concerns a universal ergonomic toothbrush, particularly adapted for persons suffering from limited mobility of the upper limbs or for personnel responsible for bucco-dental hygiene, owing to its special shape. The invention is characterised in that it consists of a trapezium associated with angular or raised flat lateral edges. The bristles are produced on only one or both sides of the active part of the brush. A planar central part is designed to receive more or less vertical tufts of bristles enabling to brush the occlusal surface of the teeth. A lateral part is designed to receive oblique tufts of bristles enabling to brush the lateral surfaces of the teeth. The combination of the active part, supporting a double row of bristles, with a large-sized angular handle, facilitates brushing by a third party, as a result of better positioning and total efficient brushing of all the surfaces of the teeth in minimum time.

Description

Brosse à dents ergonomique Ergonomic toothbrush

La présente invention concerne une brosse à dents dont les caractéristiques : disposition des touffes, anguiation de celles-ci et design du squelette, permettent un nettoyage complet avec une simplicité et une faible amplitude de mouvements.The present invention relates to a toothbrush whose characteristics: arrangement of tufts, anguishing thereof and design of the skeleton, allow complete cleaning with simplicity and low range of motion.

Ces caractéristiques synergiques en font un outil particulièrement adapté pour tous, mais en particulier pour les personnes handicapées (de façon transitoire ou durable) , et pour toute personne ayant une mobilité réduite du poignet, du bras, ou de l'épaule (arthrose, chirurgie orthopédique et problèmes neurophysiologiques) .These synergistic characteristics make it a particularly suitable tool for all, but in particular for people with disabilities (transient or lasting), and for anyone with reduced mobility of the wrist, arm, or shoulder (arthritis, surgery orthopedic and neurophysiological problems).

Cette brosse à dents est constituée de deux parties. Une partie (i) préhensive «le manche », suffisamment long et volumineux pour la mise en mouvement de la partie (2) active, couvrant une portion d'arcade de deux à quatre dents.This toothbrush consists of two parts. A prehensive part (i) "the handle", long enough and voluminous for setting in motion the active part (2), covering a portion of arch of two to four teeth.

La partie (1) peut être droite ou angulée par rapport à la partie (2), dans le plan horizontal selon qu'un simple ou double empoilage soit réalisé. Cette anguiation (α) sera de 0° à 20° (Figure 1) . La partie (1) préhensive (manche) possède une partie renflée centrale de diamètre Pc et deux parties distales plus fines d'un diamètre Pd telles que 1,5 < Pc/Pd < 3, avec Pc compris entre 12 et 20 mm.The part (1) can be straight or angled with respect to the part (2), in the horizontal plane depending on whether a single or double stacking is carried out. This anguation (α) will be from 0 ° to 20 ° (Figure 1). The prehensive part (1) (handle) has a central bulged part of diameter Pc and two thinner distal parts of a diameter Pd such as 1.5 <Pc / Pd <3, with Pc between 12 and 20 mm.

La partie (1) préhensive (manche) peut être plate avec une ou deux loges réservées au positionnement du pouce. La partie (2) active peut se présenter avec une ou deux faces travaillantes pouvant nettoyer simultanément les crois faces des dents d'une portion d'arcade du haut ou du bas ou du haut et du bas Ce principe de nettoyage simultané haut et bas a déjà été décrit, avec des caractéristiques différentes, par plusieurs auteurs ; en particulier Mr Pascal MENIER dans sa demande de brevet déposé le 18/01/89 enregistré sous le N° 8900637, Mr André PELOSSE dans sa demande de brevet déposé le 29/08/80 sous le N°8018960 et dans le brevet de Mr Manfred HAUSSER (WO 86/07527 et WO 89/01303) . La partie (2) active est composée :The prehensive part (1) (handle) can be flat with one or two compartments reserved for positioning the thumb. The active part (2) can be provided with one or two working faces capable of simultaneously cleaning the cross faces of the teeth of a portion of the arch from the top or bottom or from the top and bottom. This principle of simultaneous cleaning up and down has already described, with different characteristics, by several authors; in particular Mr Pascal MENIER in his patent application filed on 18/01/89 registered under N ° 8900637, Mr André PELOSSE in his patent application filed on 08/29/80 under N ° 8018960 and in the patent of Mr Manfred HAUSSER (WO 86/07527 and WO 89/01303). The active part (2) is composed:

1) d'une partie horizontale (a) de 8 à 15 mm de large pour la zone en rapport avec les secteurs prémolaires et molaires et de 6 à 12 mm pour la zone en rapport avec les secteurs insisivo-canins et d'une longueur (L) travaillante totale de 12 à 35 mm (figure 2).1) a horizontal part (a) 8 to 15 mm wide for the area related to the premolar and molar sectors and 6 to 12 mm for the area related to the insisivo-canine sectors and of a length (L) total working from 12 to 35 mm (figure 2).

2) de bords latéraux (b) angulés d'un angle (αl) de 15 à 80° par rapport à la partie (a) horizontale ou plats horizontaux surélevés d'une hauteur (H) de 1 à 3 mm par rapport à cette partie horizontale centrale (figures 3 et 4) .2) of lateral edges (b) angled at an angle (αl) of 15 to 80 ° relative to the horizontal part (a) or horizontal raised plates of a height (H) of 1 to 3 mm relative to this central horizontal part (Figures 3 and 4).

La partie (2) active est de forme trapézoïdale à coins arrondis, permettant un contact étroit avec les différents secteurs, molaires prémolaires et incisivo- canins, la petite base du trapèze étant la plus proche du manche (figure 2) .The active part (2) is trapezoidal in shape with rounded corners, allowing close contact with the different sectors, premolar and incisor-canine molars, the small base of the trapezium being closest to the handle (Figure 2).

Compte tenu de la forme particulière trapézoïdale de la partie travaillante, les mouvements de translation antéro-postérieurs permettent un contact étroit entre les touffes de poils et les faces de dents. Un léger mouvement de rotation du poignet permet d'atteindre les sillons gingivaux dentaires et les espaces inter-dentaires.Given the particular trapezoidal shape of the working part, the antero-posterior translational movements allow close contact between the tufts of hair and the faces of teeth. A slight movement of rotation of the wrist makes it possible to reach the dental gingival grooves and the inter-dental spaces.

Plusieurs tailles de brosses, correspondant à l'anatomie suivant l'âge de chacun, sont réalisées.Several brush sizes, corresponding to the anatomy according to the age of each, are produced.

Sur la partie horizontale de la partie active (a) , les touffes de poils de la brosse à dents sont dirigées verticalement en haut et en bas de façon à nettoyer simultanément les faces occlusales des dents supérieures et inférieures d'une même portion d'arcade ou seulement les faces occlusales en haut ou en bas d'une portion d'arcade. Ces touffes de poils dites «verticales», d'une longueur (Lv) de 3 à 9 mm sont fixées au niveau de la partie horizontale (a) du support. L'orientation des ces touffes de poils est plus ou moins perpendiculaire au plan horizontal faisant un angle deOn the horizontal part of the active part (a), the tufts of bristles of the toothbrush are directed vertically up and down so as to simultaneously clean the occlusal faces of the upper and lower teeth of the same portion of arch or only the occlusal faces at the top or bottom of a portion of arch. These tufts of so-called “vertical” bristles, with a length (Lv) of 3 to 9 mm are fixed at the horizontal part (a) of the support. The orientation of these tufts of hair is more or less perpendicular to the horizontal plane making an angle of

0°à 15e par rapport à un axe vertical perpendiculaire au plan horizontal. Ces touffes de poils «verticales» sont organisées en 2 à 5 rangées pour la partie de la brosse travaillant pour les secteurs molaires et prémolaires. D'autres touffes de poils «verticales» sont organisées en 1 à 4 rangées pour la partie de la brosse travaillant pour les secteurs canines et incisives.0 ° to 15 e with respect to a vertical axis perpendicular to the horizontal plane. These tufts of “vertical” bristles are organized in 2 to 5 rows for the part of the brush working for the molar and premolar sectors. Other tufts of “vertical” bristles are organized in 1 to 4 rows for the part of the brush working for the canine and incisor sectors.

Ces touffes de poils sont fixées des deux côtés du support (en haut et en bas) ou d'un seul côté. D'autres touffes de poils de la brosse, dites «obliques» sont dirigées obliquement à partir des bords latéraux angulés ou plats surélevés (b) de la partie active de façon à nettoyer les faces buccales et vestibulaires de chaque portion d'arcade supérieure et inférieure d'un même côté ou seulement les faces buccales et vestibulaires en haut ou en bas d'une portion d'arcade.These tufts of hair are fixed on both sides of the support (top and bottom) or on one side. Other tufts of bristles of the brush, called "obliques" are directed obliquely from the angled lateral edges or raised flat (b) of the active part so as to clean the buccal and buccal faces of each portion of upper arch and lower on the same side or only the buccal and buccal faces at the top or bottom of a portion of arch.

Ces touffes de poils «obliques» sont organisées en 1 à 3 rangées sur chacun des bords latéraux angulés ou plats surélevés (b), Elles présentent une inclinaison α2 compris entre 5e et 30° par rapport à la verticale convergent vers l'axe central(A) de la partie active (FIGURE 2, 3 et 4). Les touffes de poils «obliques» les plus proches du bord externe sont de préférence plus angulées et ceci de façon à nettoyer le tiers coronaire des dents. Les touffes de poils «obliques» les plus proches de la partie horizontale (a) sont de préférence moins angulées de façon à nettoyer le sulcus. Ces touffes de poils « obliques » sont faites de poils de 12 à 20 centièmes de mm de diamètre et d'une longueur (Lo) de 6 à 14 mm de façon à ne pas traumatiser le parodonte et organisées de préférence en touffes de 40 à 60 brins pour donner à chaque 5 touffe suffisamment de rigidité.These tufts of “oblique” hairs are organized in 1 to 3 rows on each of the angulated lateral edges or raised flat (b), They have an inclination α2 of between 5 e and 30 ° relative to the vertical converging towards the central axis (A) of the active part (FIGURE 2, 3 and 4). The tufts of "oblique" hairs closest to the outer edge are preferably more angled so as to clean the coronary third of the teeth. The tufts of "oblique" hairs closest to the horizontal part (a) are preferably less angled so as to clean the sulcus. These tufts of “oblique” hairs are made of hairs from 12 to 20 hundredths of a mm in diameter and of a length (Lo) of 6 to 14 mm so as not to traumatize the periodontium and preferably organized in tufts of 40 to 60 strands to give each 5 tuft enough rigidity.

Ces touffes de poils « obliques » situées sur les bords latéraux (b) de la partie active, sont plus longues (6 à 14 mm) que les touffes « verticales » de longueur (3 mm à 9 mm) situées sur le plan horizontalThese "oblique" tufts of hair located on the lateral edges (b) of the active part, are longer (6 to 14 mm) than the "vertical" tufts of length (3 mm to 9 mm) located on the horizontal plane.

(a) . Cette différence de hauteur est nécessaire pour que les touffes « obliques » puissent entourer les faces externes et internes des dents et que les touffes de poils « verticales » puissent nettoyer la partie triturante des dents.(at) . This difference in height is necessary so that the "oblique" tufts can surround the external and internal faces of the teeth and that the "vertical" tufts of hair can clean the triturating part of the teeth.

Dans le cas où une seule rangée de touffes de poils « obliques » sera disposée sur chacun des bords, angulés ou plats surélevés (b) , ces touffes de poils seront d'un diamètre de 1,7 mm à 2,8 mm, au niveau de leur émergence.In the case where a single row of tufts of “oblique” hairs will be placed on each of the edges, angled or raised flat (b), these tufts of hairs will be of a diameter of 1.7 mm to 2.8 mm, at level of their emergence.

L'orientation de ces touffes de poils « obliques » par rapport à un axe vertical perpendiculaire au plan horizontal est de 5° à 50°.The orientation of these "oblique" tufts of hair relative to a vertical axis perpendicular to the horizontal plane is from 5 ° to 50 °.

Les extrémités des touffes de poils « obliques » symétriques (permettant de nettoyer les faces latérales d'une même dent) sont distantes d'une longueur (d) de 5 à 8 mm pour les secteurs prémolaires et molaires et de 2 à 5 mm pour les secteurs incisivo-canins (figures 3 etThe ends of the symmetrical “oblique” bristle tufts (used to clean the lateral faces of the same tooth) are spaced by a length (d) of 5 to 8 mm for the premolar and molar sectors and from 2 to 5 mm for the incisor-canine sectors (Figures 3 and

4) . Préférentiellement, le rapport longueur des touffes obliques (Lo) /longueur des touffes verticales (Lv) est tel que 1, KLo/Lv<l, 8. 4). Preferably, the ratio of length of oblique tufts (Lo) / length of vertical tufts (Lv) is such that 1, KLo / Lv <1.8.
