Abstract

Toothbrush with interchangeable head and its device for attaching, removing and storing the brush heads. As the brush head 3 is stored vertically in the compartment 2 of the case 1, the handle 20 makes it possible, when the user inserts the stud 22 in the hole 16 of the brush head and when he applies a horizontal pushing action thereon, to pivot the brush head to the end of the overhang 21 of the handle and, simultaneously, to pivot it in the case 1 so that the brush head fits into the handle thus offering a toothbrush which is ready for use. The operation performed in reverse makes it possible to re-place the brush in its compartment and to release it from its handle which is thus ready to receive another brush head.

Description

La pur sente inventinn concarne une brosse à dents b tête interchangeable et son dispositif d'accrochage, décrochage et stockage des types de brosses de rechange. The pure inventinn path concerns a toothbrush with interchangeable head and its attachment, detachment and storage device for types of replacement brushes.

Des dispositifs qui permettent de séparer la brosse du manche d'une brosse à dents éxistent: soit que l'éjection de la brosse s'effectue à l'aide d'un ressort; soit qu'il s'agit d'un bouton pressoir: soit que c'est le manche qui devient remplacable car contenant du dentifrice, ou soit que la manche s'introduit sur une partie de sa longueur dans la brosse jetable. Devices that allow the brush to be separated from the handle of a toothbrush exist: either that the brush is ejected using a spring; either it is a press button: either it is the handle which becomes replaceable because it contains toothpaste, or either the sleeve is introduced over part of its length into the disposable brush.

Le dispositif selon l'invention est différent dans sa conception et propose en soi une fonction cohérente accrochage dc'crochage-stockag pour le produit brosse-manche. Il s'agit d'une part, d'une brosse dont les têtes de brosse s'otent et se remettent grâce à un système de rotation du manche de la
Grosse à l'intérieur de la tte de brosse et d'autre part, d'une boite dans laquelle sont stockées les têtes de brosse.The device according to the invention is different in its design and in itself offers a coherent hooking, hooking and storage function for the brush-handle product. On the one hand, it is a brush, the brush heads of which are removed and replaced by a system of rotation of the handle of the
Large inside the brush head and on the other hand, a box in which the brush heads are stored.

La tête de brosse étant stocke dans l'un des compartiments de 13 boite, le manche dermes, lorsque l'utilisateur introduit l'ergot arrondi du manche dans le trou le plus large de la tette de brosse et lorsqu'il lui applique une poussée horizontale ou d2 haut en bas , d'encastrer lechancrure de la tête de brosse sur l'avancée plus mince du manche et de clipper dans les deux petits trous situés sur les côtés latéraux de la tête de bros se, les deux pitons disposés en,regard sous cette avancée sur les faces internes des deux parois prolongeant les cotés du manche. La tête de brosse est alors solidaire du manche offrant une brosse à dents prête à l'emploi.Lorsqu'il veut retirer la brosse du manche, l'utilisateur opère alors en sens inverse en introduisant la brosse dans le compartiment. S'il applique une poussée de bas en haut il libérera le manche de la t8te de brosse et la replacera dans sa position d'origine. The brush head being stored in one of the 13 box compartments, the dermal handle, when the user introduces the rounded lug of the handle into the widest hole of the brush head and when he pushes it horizontal or d2 top to bottom, to embed the notch of the brush head on the thinner projection of the handle and to clip in the two small holes located on the lateral sides of the head of bros se, the two pitons arranged in, look under this projection on the internal faces of the two walls extending the sides of the handle. The brush head is then secured to the handle providing a ready-to-use toothbrush. When he wants to remove the brush from the handle, the user then operates in the opposite direction by inserting the brush into the compartment. If it applies a push from bottom to top it will release the handle of the brush head and return it to its original position.

L'utilisateur n'aura plus qu'à en dégager le manche prêt à recevoir une autre tête de brosse voisine.The user will only have to release the handle ready to receive another neighboring brush head.

Le dispositif représenté figure 1, 2, et 3 comporte une tête de brosse (3) et un manche (20):
Une tate de brosse qui à un bout et sur chacun des deux côtés latéraux (9) et (1D) dispose de deux petits trous (11) (12) et 413) (14) ainsi qu'un petit sillon en biais (15) dans le prolongement de deux d'entre eux (11) et (13). A l'autre bout et à gauche du côté latéral gauche (10), les poils de la tête de brosse étant dirigés vers le bas, est creusé un trou (16) plus large, qui dans une partie de sa longueur (17) posséde un périmètre fermé aux deux tiers environ et ouvert sur un tiers, et dans l'autre partie (18) possède un périmètre fermé lui dans sa totalité, formant ainsi pour partie, une cavité à l'intérieur de la matière.Sur le haut de la tête de brosse une échancrure (19) prolonge en s'évasant la partie (17) du trou (16) non fermé au un tiers.The device represented in FIGS. 1, 2, and 3 comprises a brush head (3) and a handle (20):
A brush tate which at one end and on each of the two lateral sides (9) and (1D) has two small holes (11) (12) and 413) (14) as well as a small diagonal groove (15) in the extension of two of them (11) and (13). At the other end and to the left of the left lateral side (10), the bristles of the brush head being directed downwards, a larger hole (16) is dug, which in part of its length (17) has a perimeter closed about two-thirds and open on a third, and in the other part (18) has a perimeter closed him in its totality, thus forming in part, a cavity inside the material. the brush head a notch (19) extends by flaring the part (17) of the hole (16) not closed to a third.

Un manche dont l'extrémité avant comporte une avancée (21), nettement moins épaisse que le manche lui même qui sur l'un des côtés va en s'amincissant dans sa largeur. Cette avancée se termine par un ergot arrondi (22) qui déborde dans l'inté
rieur de la 7 ardeur et sur un peu moins de la largeur du
manche. Au début et dessous cette avancée (21) le manche est
creusé de telle sorte qu'il se dégage deux petites parois (23)
et (24) dans le prolongement des deux cotés du manche. Ces
parois disposent au milieu et sur leur face intérieure, de
deux petits pitons (25) et (26) en regard, qui viennent se
clipper dans les trous (12) et (14) de la tête de brosse.A handle whose front end has a projection (21), much thinner than the handle itself which on one of the sides tapers in width. This projection ends with a rounded lug (22) which projects into the interior
laughing at the 7 ardor and a little less than the width of the
handle. At the beginning and below this advance (21) the handle is
dug out so that two small walls (23) emerge
and (24) in the extension of the two sides of the handle. These
walls have in the middle and on their inner face,
two small pitons (25) and (26) facing each other, which come
clip into the holes (12) and (14) of the brush head.

La partie arrière du manche est:
sur le dessus: légèrement bombée.The rear part of the handle is:
on top: slightly domed.

sur le dessous: dans la prolongement de l'espace situé entre
les parois (23) et (24),incurvéevers l'intérieur retombant pro
gressivement jusqu'a environ la moitié pour finir droit et
plat jusqu'au bout extérieur du manche.on the underside: in the extension of the space between
the walls (23) and (24), curved towards the inside falling down pro
gressively until about half to finish right and
flat to the outside end of the handle.

Les côtés du manche sont: tout d'abord parallèles entre eux du
bout extérieur jusqu'a un peu moins de la moitié, puis recti

l'un des côtés filant ensuite droit jusqu'au bout de l'avancée
(21), tandis que l'autre s'incline brusquement d'environ 55
degrés jusqu'au début de l'avancée où il se redresse nettement
jusqu'a l'ergot(22) puLse découpe dans l'intérieur et dans un
peu moins de la largeur du manche.The sides of the handle are: first of all parallel to each other

of the handle where the projection is located (21), then r ectilinear
and tilt outwards to the beginning of the walls (23) and
(25), then again parallel in the length of these walls,
one side then running straight to the end of the advance
(21), while the other suddenly tilts by about 55
degrees until the start of the advance where it straightens clearly
to the lug (22) puLse cuts in the interior and in a
little less than the width of the handle.

Le dispositif représenté figure 13 montre comment l'ergot (22) du manche (20) vient se loger dans le trou (16) de la tête de brosse, comblant entièrement les espaces (17) et (18).L'avancée (21) de ce même manche s'encastre dans l'échancrure (19) de la tête de brosse. The device shown in Figure 13 shows how the lug (22) of the handle (20) is housed in the hole (16) of the brush head, completely filling the spaces (17) and (18). ) of the same handle fits into the notch (19) of the brush head.

Le dispositif représenté figures 4 à 8 et figures 9 à 12 comporte deux types de boite (1) possédant Soute3 deux plusieurs compartiments (2) dans lesquels sont stockées les hrosse (3). The device shown in Figures 4 to 8 and Figures 9 to 12 comprises two types of box (1) having Soute3 two several compartments (2) in which are stored the harrosse (3).

Chacun des deux côtés latéraux de ces compartiments dispose, à l'intérieur et à environ un tiers du haut, d'un point de serra ie (4) en relief permettant de retenir la tête de brosse. A fleur de chacun des côtés-gauche de ces compartiments (2), se découpe une ouverture (6) située entre le haut de la boite et le point de serrage (4) en relief sur ce même côté. Cette ouverture permet à l'ergot (22) du manche d'accéder dans le trou (16) de la tête de brosse.Each of the two lateral sides of these compartments has, inside and about a third of the top, a clamp point (4) in relief allowing the brush head to be retained. Flush with each of the left-hand sides of these compartments (2), there is an opening (6) located between the top of the box and the tightening point (4) in relief on this same side. This opening allows the lug (22) of the handle to access the hole (16) of the brush head.

Le dispositif représenté figures 4 à s comporte,,selon un premier mode, une boite (1) disposant en outre, à environ un tiers du bas, d'un petit piton (5) sur lequel la brosse prend appui pour effectuer sa rotation. Le fond (7) de la boite est un arc d'environ un tiers de cercle. A un peu moins du quart sur le fond à l'intérieur de la boite, se trouve une buttée (8) qui se prolonge sur chacun des côtés des différents compartiments (2). Cette buttée forme avec la tangente au point dtin- tersection de la buttée et du fond, un angle B d'environ 100 degrés. Une fine buttée(29) longe en facade chacun des côtés droit des compartiments (2).Elle commence au niveau du point de serrage (4) et se termine eu milieu du côtés empéchant la brosse de sortir verticalement hors de la boite (1). Le socle (28) de cette boite est plat. Il forme avec la tangente au point d'intersection du socle et du fond, un angle tel u-- 12 boite tienne debout en éouilibre sur son sole. Chacun de des côtés des compartiments(2) forment, eu niveau d'un point se situant dans le prolongement des buttées (8), un angle (30) 'laro--issant les dits côtés vers l'extrémité du socle de 1 boite. Les trous (11) et (13) permettent à la têtue de brosse d'effectuer sa rotation dans la boite (1) en tournant sur les pitons (5) de cette même boite.Les deux sillons (15) en biais et en prolongement des trous (11) et (13) de la tête de brosse (3) permettent en rippant sur les pitons (5) de dégager la tête de brosse de son compartiment (2) eprés qu'elle ait effectuée sa rotation de la verticale vers l'horizontale. The device shown in Figures 4 to s comprises ,, in a first embodiment, a box (1) further having, about a third of the bottom, a small piton (5) on which the brush is supported to perform its rotation. The bottom (7) of the box is an arc of about a third of a circle. At a little less than a quarter on the bottom inside the box, there is a stop (8) which extends on each side of the different compartments (2). This abutment forms with the tangent at the point of intersection of the abutment and the bottom, an angle B of approximately 100 degrees. A fine stop (29) runs along the front of each of the right sides of the compartments (2). It begins at the clamping point (4) and ends in the middle of the sides preventing the brush from coming out vertically out of the box (1) . The base (28) of this box is flat. It forms with the tangent at the point of intersection of the base and the bottom, an angle such as u-- 12 can hold upright in equilibrium on its sole. Each of the sides of the compartments (2) form, at a point located in the extension of the abutments (8), an angle (30) 'widening the said sides towards the end of the base of 1 box . The holes (11) and (13) allow the stubborn brush to rotate in the box (1) by turning on the pins (5) of the same box. The two grooves (15) at an angle and in extension holes (11) and (13) of the brush head (3) allow by ripping on the pins (5) to release the brush head from its compartment (2) after it has rotated from vertical to the horizontal.

Le dispositif représenté figures 9 à 12, comporte, selon un deuxième mode, une boite non plus arrondie mais rectangulaire, dont le côté (27) est obstrué sur environ deux tiers et ouvert sur environ un tiers. La tête de brosse est placée dans cette boite de telle sorte qu'au trou (16) corresponde l'ouverture (6) et que la partie où sont situés les trous (12) et (14) repose à fleur sur le côté (27), comme pour venir combler l'espace que ce même côté à laissé vide. La buttée (8) qui court à l'intérieur des compartiments (2), est dans ce cas pa tallée au socle de la boite et forma un angle droit avec le côté (27) contre lequel elle s'appuie. Loreque l'utilisateur introduit le manche (20) dans le trou (16) de la tête de bros se, celle ci restant fixe, il oblige le manche dans un mouve msnt de rotation de haut an bas en venant clipper les trous (12) et (14) de la tête de brosse sur les pitons (25) et (26) du manche. Une légère poussée vers le haut permettra de dégager l'ensemble brosse-manche de la boite (1) rectangulaire. The device shown in FIGS. 9 to 12 comprises, according to a second mode, a box which is no longer rounded but rectangular, the side (27) of which is obstructed for approximately two thirds and open for approximately one third. The brush head is placed in this box so that the hole (16) corresponds to the opening (6) and the part where the holes (12) and (14) are located rests flush on the side (27 ), as if to fill the space that this same side left empty. The abutment (8) which runs inside the compartments (2), is in this case pa tallée to the base of the box and formed a right angle with the side (27) against which it rests. Loreque the user introduces the handle (20) in the hole (16) of the head of bros se, this one remaining fixed, it forces the handle in a msnt movement of rotation from top to bottom by clipping the holes (12) and (14) from the brush head to the pins (25) and (26) of the handle. A slight push up will release the brush-handle assembly from the rectangular box (1).
