Definitions

  • the present invention relates to the manual cleaning of teeth; more specifically, to a toothbrush comprising a head and a handle whereby the head is situated substantially perpendicularly to the longitudinal axis of the handle, namely by bristles directed substantially in a right angle to the plane in which the longitudinal axis of the handle lies, whereby a neck is arranged between the handle and the head.
  • any dental practitioner will confirm that the most frequent bad habit of people in cleaning their teeth is that they do not clean their teeth by vertical motions, but rather in the manner implied by the classic brush shape (i.e. in a horizontal direction) .
  • Cleaning teeth in this way is less effective for the gums due to the impact of the brush retreat, particularly in the area of incisors, such that the tooth necks is bared increasing the likelihood of periodontal disease.
  • DE 34 23 400 Al describes a brush with a head located perpendicularly to the handle, the bristles being situated in the plane of the brush whereby the head is offset from the handle to enable the easy application of toothpaste.
  • a toothbrush with an unsymmetrical handle position which solves the problem of how to increase its ergonomics by changing the structure.
  • the handle axis is directed at a certain angle to the brush head axis of symmetry.
  • the handle occupies a position where the brush head is displaced by a simple movement along its axis in the direction of tooth gaps to clean them effectively.
  • the head is exchangeable in such a way that its bearing in the centre of gravity can be mounted to an axis on a holder. Both, the bearing and the axis are connected by mutual click allowing simultaneously the head to remain flexible and aligned uniformly against teeth. After fixing, it can be adjusted for the left-hand or right-hand application.
  • the object of the present invention is to provide a simple and reliable means to facilitate a healthy method of teeth-cleaning which would enable easy manufacture, operation, reliability, and optimal cleaning even of the marginal teeth with a minimum of effort.
  • a toothbrush comprising a head and a handle where the head is situated substantially perpendicularly to the longitudinal axis of the handle, namely by bristles directed substantially in a right angle to the plane in which the longitudinal axis of the handle lies, whereby a neck is arranged between the handle and the head.
  • the neck is arranged in the form of capital S, whereby the extended longitudinal axis of the handle passes at least through the projection of the head into the above said plane of the handle longitudinal axis or in its proximity.
  • An advantageous embodiment includes a rotatable joint associated with the head to enable its turning, advantageously through 180 degrees.
  • Another advantageous embodiment consists in the joint disposed between the head and the neck, or on the neck close to the head.
  • the axis of the head and the neck lie in the same plane.
  • the head lies in the same plane as the axis of the handle and the neck. More preferably, the head is inclined in respect to the plane of axis of the handle and the neck into the bristles side at an angle up to 15 degrees, preferably at an angle 10 degrees, whereby the inclination point lies between the head and the joint.
  • the upper portion of the neck includes, with respect to the handle axis, an angle of 75 to 90 degrees, advantageously at 90 degrees.
  • the lower portion of the neck forms with the axis of the handle an angle - A -
  • the distance between the upper arch and the handle is 1.5 - 2.5 times, preferably two times the length of the head.
  • the distance between the lower arch and the handle is 1.0 - 2.5 times, preferably two times the length of the head.
  • the joint consists of a dismountable system of tongue and groove whereby the tongue has a square or rectangular cross-section and the mutual blocking and fixing of the head on the neck is carried out by means of a catch in the form of an 0-ring.
  • the joint may consist of a connection with a longitudinal motion of the head which is provided with a tongue of circular cross-section whereby the tongue has a bearing element, the neck is provided with a groove having a circular cross-section at its outer end and having a fixing portion at its inner end which portion comprises a stop which is disposed parallel to the axis of the joint and projects inside the groove; and, in order to prevent longitudinal motion of the head, the joint is provided with a catch in the form of an 0-ring.
  • both the opposite edges of the bearing element are provided with offset abutment surfaces disposed symmetrically along the axis of the joint, whereby the catch has two steps.
  • the joint may include a fixing mechanism where the head is connected to the neck of the brush by a tongue-groove system of circular cross-section whereby the fixing mechanism passes through the tongue and the groove at a right angle with respect to the rotation axis and the joint (1) is secured by a catch in the form of an 0-ring.
  • the fixing mechanism comprises opposite pistons disposed perpendicularly to the axis of the joint, the outer face of said pistons being engaged by tumblers whereby the pistons are pre-stressed by at least one spring.
  • the tongue is provided with a bearing element and the groove at its end with a stop whereby the tongue and the groove are disposed parallel to the axis of the joint and the stop projects into the groove to ensure the engagement with the bearing element.
  • the toothbrush (hereinafter referred to also as the "S- force") according to the present invention is unique in its neck shape which suggests a letter S, or the top of a fire hook. This shape enables cleaning of the surfaces of the 4 to 8 molar teeth which otherwise would be to a great extent inaccessible.
  • the "S-force” is equipped with a joint for the turning of the brush head by 180 degrees including its fixing in the end positions. The combination of these two features provides for comfortable but primarily very effective cleaning of all tooth areas, i.e. their front part, their rear part, and the masticating surfaces of molars. •
  • the "S-force" utilizes an absolutely standard brush head and a standard handle. At a shop counter anybody would recognize it at first sight as a toothbrush. Although rather curved, it is in all other respects clearly a toothbrush.

  • Fig. 2 is a side view of the toothbrush according to the invention of Fig. 1
  • Fig. 3 is a longitudinal sectional view of a first embodiment of a dismountable joint between the head and neck of the toothbrush
  • Fig. 4 is a sectional view of the head and neck of the toothbrush along a plane A-A of Fig. 3

  • Fig. 9 shows the process of cleaning the upper teeth with the toothbrush held in the left position.
  • Fig. 1 shows an "S-force" toothbrush with a head 3, in the right-hand position.
  • This front view shows that the longitudinal axis of the handle 4 intersects approximately with the centre of the brush head 3.
  • Such arrangement is advantageous in reducing the rotation of the toothbrush in cleaning teeth as a result of non-coaxial forces exerted on the brush head 3.
  • a shift of the brush head 3 outside this axis is generally also possible.
  • the neck 2 i.e. an intermediate part between the handle 4 and the brush head 3 is formed like the working part of a poker.
  • the neck 2 is situated in the same plane as the handle 4 whereby the head 3 lies substantially in this same common plane.
  • the bristles are disposed substantially perpendicularly to this plane.
  • both the arches 2a, 2b may be of the same or similar size
  • the lower arch 2a provides for a declination of the lower part of the handle 4 at an angle of 70 to 45 degrees, preferably at about 60 degrees from the axis of the handle 4 at the point at which the handle 4 passes into the lower part of the neck 2.
  • the upper arch 2b located between both parts of the neck 2 provides for the positioning of the upper part of the neck 2 at an angle of approximately 75 to 90 degrees, preferably at about 90 degrees with respect to the axis of the handle 4.
  • the upper arch 2b is located at a distance corresponding to 1.5 to 2.5 (preferably two times) the length of the brush head 3 whereby the distance between the lower arch 2a and the head 3 is about 1.0 to 2.5 times the length of the head 3.
  • the actual dimensioning of the size of the arches 2a, 2b, the neck 2, the length of head 3 and the thickness of the neck 2 will depend on the individual age groups for which the brush is designed, the choice and location of the joint 1, the hardness of the brush, dimensions and shape of individual parts of the brush, and so on.
  • Fig. 2 shows that, in the illustrated preferred embodiment of the brush, both the handle 4 and the neck 2 are situated in one plane which enables a comfortable grip on the brush from both sides, i.e. with the head 3 either in the left-hand position or in the right-hand position.
  • the head 3 is then located close to this plane or directly in this plane, as the case may be. More preferably, the head 3 is inclined in respect to the plane of axis of the handle 4 and the neck 2 in the direction of bristled side of the head 3 at an angle up to 15 degrees, preferably at an angle 10 degrees. It means in cleaning position towards teeth and to the left according to Fig. 2.
  • the inclination point lies between the head 3 and the joint 1.
  • Fig. 1 and 2 show such an arrangement of the joint 1 between the neck 2 and the head 3 where the head 3 may be turned from the right position to the left position through 180 degrees.
  • the joint 1 is arranged as a dismountable connection between the head 3 and the neck 2 of the brush.
  • the head 3 and the neck 2 are connected by the tongue and groove system.
  • the tongue has a quadrate or, more appropriately, rectangular cross-section.
  • the rectangular cross-section enables the head 3 to be fixed on the neck 2 in two 180 degree mutually turned positions only.
  • the blocking/fixing of the head 3 on the neck 2 is secured by a catch 5 in the form of an O-ring.
  • the O-ring will be released by pulling the head 3 to the right in the direction of the arrow Al (Fig. 3) . This means that the head 3 is separated from the neck 2.
  • the head 3 is turned in the direction of arrow A2 by the required angle which may be for some applications even 90 degrees. Thereafter, the head 3 is secured by pressing it to the left in the direction of arrow Al and by pushing back the flexible O-ring catch 5.
  • This embodiment is very simple and easy to implement technically.
  • a second embodiment of the joint 1 according to Fig. 5 and 6 may by interpreted as a joint with a "longitudinal sliding motion of the brush head 3".
  • the head 3 is provided with a tongue 6 showing a circular cross-section at its inner end.
  • the outer end of this tongue 6 is fitted by a flat bearing element 8.
  • Both opposite edges of the bearing element 8 are provided with offset stop surfaces 9 situated symmetrically along the axis of the joint 1.
  • the neck 2 has a groove of circular cross-section at its outer end.
  • a fixing portion 10 is provided.
  • This portion comprises a stop 7 which is disposed parallel to the axis of the joint 1 and projects in the inside of the groove.
  • the fixing portion 10 of the groove has a substantially rectangular cross-section (see Fig. 6) at a length C.
  • the cross-section of the tongue 6 is transformed from the flattened shape of the bearing element 8 into a circular cross-section.
  • the catch 5 also has the form of an 0-ring but is carried out as a two-step catch which may take two positions enabling the head 3 to be longitudinally moved with respect to the neck 3 over a distance C .
  • the head 3 For turning the head 3 it is first displaced to the left in the direction of the arrow B (Fig. 5) over a distance C, for example by about 5mm. Thus, the flat bearing element is released from the flattened fixing portion 10 but still remains in the range of the stop 7. This position is secured in that the length E of the stop 7 is greater than the distance C at which the head 3 is shifted. The distance C is at least equal, advantageously a bit greater than the length C of the fixing portion 10.
  • the head 3 is turned by 180 degrees in the direction of the arrow shown in Fig. 6 and abuts its opposite stop surface 9 to the stop 7. Thereafter, the bearing element 8 is inserted back into the fixing portion 10 in the direction of the arrow B to the left. In the working position of the brush, the bearing element 8 of the tongue 6 engages the stop 7 and is fixed at the flattened fixing portion 10 of the groove .
  • This second embodiment of the joint is more complicated from the technical aspect, but more effective for the user of the brush.
  • a third embodiment of the joint 1 according to Fig. 7 may be interpreted as a "fixing mechanism joint without sliding motion" since this joint 1 enables only the turning of the head 3.
  • the head 3 is again connected to the brush neck 2 by the principle of tongue and groove.
  • the tongue 6 and the groove are of circular cross-section.
  • a fixing mechanism passes through the tongue 6 and the groove along the rotation axis. If the projecting rubber surfaces 11 are pressed by two fingers in the direction of arrows D, the pistons 12 urge the tumblers 13 into the body of the tongue 6. Then, the brush head 3 may be turned through 180 degrees. After releasing the projecting surfaces 11, the tumblers fix the head 3 in all directions by means of a spring 14.
  • the catch 5 is non-dismountable and enables the turning of the head 3 on its longitudinal axis only.
  • This third embodiment of the joint 1 is most technically challenging and requires the use of high-quality materials in consideration of the small space in which the joint 1 is to be built (i.e. of an axial support) .
  • the joints 1 may be mutually combined.
  • the third embodiment may be completed by a stop 7 which is utilized in the second embodiment.
  • Other combinations are also possible.
  • the process of cleaning the teeth is absolutely identical for both positions of the brush head 3, i.e. for the left-hand or right-hand positions.
  • Fig. 8 shows the motions that may be used for effective cleaning of teeth on the lower-left side.
  • the outer part is cleaned by upward motions from the down position whereby the brush handle 4 is directed downward.
  • the inner sides of the teeth are also cleaned by upward motions from the down position, although here the brush handle 4 is pointed upward.
  • the "chewing surfaces” are cleaned in a horizontal direction (as the horizontal arrow directs), whereby the brush handle 4 is also held in the horizontal position.
  • Fig. 9 shows what motions are necessary to clean the upper teeth effectively.
  • the outer part of the front teeth and those on the left side are cleaned by motions from the top downward, whereby the handle 4 is pointed downward.
  • the front inner sides and right upper sides are cleaned by turning the handle 4 in the hand also by a motion from the top downwards, whereby the handle 4 is again directed downward.
  • the teeth "chewing surfaces" on the upper right side are cleaned in the horizontal direction as indicated by the horizontal arrow, whereby the handle 4 is also held in the horizontal position.
  • the above-described cleaning procedure provides the most advantageous approach when the handle 4 and the neck 2 of the brush are situated preferably in one plane which enables a grip on the brush from both sides, i.e. with the head 3 in the left position or with the head 3 in the right position.
  • Such an arrangement enables simple manufacture and easy handling when using the brush.
