Benefits of technology

[0010]The object of the present invention, with respect to the above-cited prior art, 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.
[0020]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. Moreover, 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.

Problems solved by technology

Generally, 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.
With the classic toothbrush, such motion is not ergonomic and almost impossible to achieve given the hasty cleaning of teeth and lack of focused concentration typical of the everyday user.
Further, DE 94 19 778 U1 discloses a known cleaning device for the mouth cavity which however does not provide for simple overcoming said disadvantages and problems.

first embodiment

[0039]In the first embodiment, according to FIGS. 3 and 4, 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. When the turn of the head 3 in the direction of arrow A2 by 180 degrees is required, the O-ring will be released by pulling the head 3 to the right in the direction of the arrow A1 (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 an...

second embodiment

[0040]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”. Here, 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. At its inner 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. At the end of the stop 7, the cross-section of the tongue 6 is transformed from the flattened shape of the bearing element 8 into a circular cross-section.

[0041]The longitudinal sliding motion of the he...

Abstract

A toothbrush comprises a head (3) and a handle (4) where the head (3) is situated substantially perpendicularly to the longitudinal axis of the handle (4) namely by bristles directed substantially in a right angle to the plane in which the longitudinal axis of the handle (4) lies, whereby a neck (2) is arranged between the handle (4) and the head (3). The neck (2) is arranged in the form of a capital S, whereby the extension of the longitudinal axis of the handle (4) passes at least through the projection of the head (3) into the above said plane of the longitudinal axis of the handle (4) or in its proximity.

Description

TECHNICAL FIELD[0001]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.BACKGROUND ART[0002]Generally, 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.[0003]One of the most effective preventative actions to st...
