Definitions

• the present invention relates to a toothbrush intended in particular, but not exclusively for veterinary use for the dental cleaning of canids and / or felines.
• toothbrushes consisting of a rectilinear handle, one end of which is provided with bristles, constitutes the working head, are not practical to use for an operator who generally performs cleaning in front of the animal. . Given the particular shape of the animal jaw, these brushes indeed require significant angular displacements to treat the entire dental surface; these movements do not allow optimal brushing efficiency and do not facilitate the work of the technician who must at the same time firmly maintain the animal, often agitated constantly. Cleaning should be done in front of the animal.
• the present invention aims to provide a tool suitable for veterinary use, allowing easy and effective brushing of the teeth of all types of animals. bed for this purpose, the head of the brush forms an angle of 135 ° envi ⁇ ron with the handle and has one or two pins placed on one side or on either side of the handle and located about 3 cm before the curvature .
• the first variant is a one-piece toothbrush.
• the second variant is a toothbrush with interchangeable heads.
• the sleeve then ends with a male part of hexa ⁇ gonal section avoiding any rotation of the interchangeable part.
• the interchangeable head includes a hollow female part of hexa ⁇ gonal section which fits by friction on the handle. This friction is exerted over a length of approximately 3 cm, which allows good stability of the head in its housing. It is necessary to exert a pressure to obtain the nesting aximun. The disinsertion is done by simple simultaneous pull of the two parts. This interchangeable head is bent at an angle of 135 °.
• the third variant is a toothbrush according to the invention which consists of a brush-shaped working head, integral with a grip handle and offset towards the outside, set back with respect to the axis of said handle. .
• the working head is preferably connected to the handle by an intermediate extension.
• the toothbrush has a head oriented at an angle of 40 to 50 ° around the axis of the handle; this angle is preferably about 45 °.
• the toothbrush has a "tool" handle, consisting of a substantially cylindrical body, curved on the back. This handle is formed to be easily gripped in the hand. Its length is suitable for good positioning in the hand of the user, its end being intended to come to rest in the bottom of the palm, at the level of the hypothenar eminence.
• this brush comprises a handle, the back of which is provided, at least on its front part, with a longitu ⁇ dinal boss, projecting forming a rotation guide.
• This boss constitutes an ap ⁇ permi to print a movement of the roll of the handle, by means of the thumb or the index finger for example, to easily rotate the brush in one direction or the other the handle-tool association and rotation guide ensures any type of grip, regardless of the size of this hand.
• the toothbrush comprises a protection and blocking lug arranged in the extension of the back of its sleeve, at the connection of the extension of the head.
• REPLACEMENT SHEET 3 This lug allows support of the thumb or the index finger of the user, thus ensuring stability, guidance and precision; it also provides protection for your thumb and hand to prevent them from abutting the animal's teeth or accidental bite.
• the brushing head consists of a support in which tufts of bristles are implanted, said bristles having lengths determined so as to define a convex brushing surface. .
• the central bristles of the brush thus have a greater length than the bristles of extremity.
• the bristles used are chosen from among the most flexible.
• Figure 1 is a side view of the first variant. It shows the angle of about 135 ° (a) formed between the handle and the head as well as the pins (b) located on either side of the handle.
• Figure 2. is a side view of a toothbrush according to the invention. It shows the interlocking system (a) and the 135 ° angle (b) formed between the handle and the head as well as the pins (c) located on either side of the handle.
• Figure 3 is a view of the male part of the hexagonal section of the handle.
• Figure 4 is a view of sections of the handle aa and bb
• Figure 5 is a view of the interchangeable head showing the detail of the female part of hexagonal section, the hollow part terminating in conical shape.
• Figure 6 is a side view of the toothbrush according to the invention.
• Figure 7 is a section along 2-2 of Figure 6.
• Figure 8 is a partial view showing the connection of the working head to the intermediate part.
• the toothbrush consists of a working head 1 secured to the grip handle 2 by an intermediate part 3.
• the brushing head 1 consists of a support plate 4 in which the bristles 5 are located, in tufts, which form the actual brush.
• the intermediate part 3 is in the form of an extension of the support 4 and it is connected to the end of the handle 2, offset from the longitudinal axis 6 of the latter.
• This offset at an angle a. on the order of 40 to 50 ° and preferably around 45 °, is made outwards, on the back side 7 of the handle 2.
• the brushing head 1 is therefore set back relative to the longitudinal axis 6 of the handle 2 and the active part of the bristles 5 implanted in the support 4 is oriented towards this axis 6.
• the head 1 is moved away from the end of the handle 2 and from the elbow of the tool by virtue of the inclined intermediate part 3.
• the length of this intermediate part 3 is suitable for any type of animal * , this length of the around 7 to 10 cm, preferably corresponds to the longest jaw length in large dogs, starting from the corner of the lips.
• the handle 2 is in the form of a "tool" handle. It consists of a body which is substantially cylindrical and slightly rounded at the level of the rear part of the back 7.
• the handle 2 has a slightly increasing diameter from the front towards the rear; the average diameter is of the order of 2 to 2.5 cm.
• the length b_ of the handle is of the order of 10 to 13 cm; it is suitable for correct positioning and good holding in the operator's hand, whatever its size. This length must in fact allow the end of the handle to come to rest in the bottom of the operator's palm, against its hypothenar eminence.
• This length adapted to the particular shape of the handle, allows excellent locking of the tool, necessary for its use for the treatment of animals that are sometimes recalcitrant.
• the base of the handle 2 has a flat 2a which determines a laying surface for the tool, with the head 1 suréle ⁇ vée.
• This characteristic has advantages at the practical level and also at the hygienic level by avoiding the contact of the bristles 5 with the support surface.
• the angled connection zone between the extension 3 of the head 1 and the sleeve 2 has a protective and locking lug 8, projecting.
• This lug 8 is disposed on the curvature of the tool, in the extension of the back 7 of the handle 2; its front area 8a. allows the creation of an obstacle to avoid contact of the technician's fingers or hand with the animal's teeth. Its rear zone 8b can be adapted, slightly recessed, for setting the thumb or the index finger of the manipulator according to the dental regions to be cleaned. This characteristic makes it possible to improve the blocking, the guiding, the stability and the precision of the tool.
• the wedging zone 8b_ can advantageously be provided with anti-slip grooves 8 £, projecting. The positioning of this lug 8, in the acute angle formed by the handle and the extension 3 of the support 4, makes it possible to obtain effective protection during brushing, during the coming and going of the tool, or against certain aggressiveness of the animal.
• a longitudinal boss has been provided on the front part of the back 7 of the handle 2, visible in section Figure 7.
• This boss in the form of a rotation guide 9 s' extends from the base of the lug 8 to substantially the central part of the handle 2; it constitutes a support for the thumb or the fingers of the manipulator making it possible to impart a roll movement of the handle 2 in the hand, which roll movement is useful in particular for changing the brushing side.
• the guide 9 also makes it possible to support the finger in the stopped position, at the choice of the user and whatever the angle of rotation chosen.
• the brushing quality of the animal's jaw is improved by a particular conformation of the brushing surface produced by the association of the bristles 5.
• the bristles 5 are implanted in tufts in the support plate 4 in a conventional manner.
• the number of tufts and the number of bristles, associated with their tightening, are adapted according to the desired brushing surface.
• This brushing surface can vary on the order of 1 to 3 cm 2 depending on the animal to be treated. It is thus possible to provide a brush comprising 24 to 42 tufts of bristles extending over three or four parallel rows.
• the jaws of canines in particular are not straight; it presents, laterally, a concave curvature.
• the brush head has been adapted to this particular configuration by providing end bristles 5a_ which are shorter than the central bristles 5b.
• the end bristles 5a_ can have a length of the order of 0.6 cm and the central bristles a length of 1 cm; the intermediate bristles have a length comprised between these two values so as to give the brush a convex, smooth bros surface, visible in FIG. 6.
• the brushing surface corresponds to an arc of a circle whose radius is around 2.43 cm. This particular shape of the clean brush allows the tangent of the arc to creep into the recesses and improve the quality of cleaning.
• the gestures require less precision on the part of the technician and this shape also makes it possible to facilitate the gripping of toothpaste from a packaging jar.
• the plate 4 of the working head 1 seen from the back, and connected to the intermediate part 3 which extends in the same plane.
• the intermediate part 3 narrows from the handle 2 towards the plate 4 to form a wedge which connects to said plate by forming two lateral throttles 10.
• the support plate 4 preferably has rounded edges to make it as atraumatic as possible in the event of contact with the jaw of the animal.
• the toothbrush according to the invention is obtained in one piece, with the exception of the bristles 5, by molding a plastic material such as polypropylene.
