DE4115943C2 - Gum massage brush - Google Patents

Description

The invention relates to a gum massage brush according to the preamble of Claim 1. It is for the care and treatment of those in the oral cavity Gums, for massaging and cleaning.

The bristle bundles, which are in one Brush body with the bristle ends through contact with the gum tissue Promote and activate the blood circulation, so that the teeth are firm and healthy in upper and Preserve the lower jaw as long as possible. To consolidate the whole Tooth retention apparatus, however, it is necessary that the bristle bundle with the Bristle ends not only the visible gum side with the interdental spaces but also the inside of the gums with the adjacent ones Interdental spaces at the transition to the tooth hem.

A cleaning effect is particularly desirable here at the tooth hem, because at these points dental plaque forms, which hardens all around the tooth hem and causes inflammation, if this so-called plaque is not removed thoroughly and completely. Rear Area of the gums with the interdental spaces and the adjoining Toothed edges cannot and will not be attainable with conventional toothbrushes totally neglected. Due to the jaw arches there is only one above and below partial contact of the bristle bundles on the gums is possible. In the upper as in the lower incisor area, brushing can only be done vertically upwards, respectively only vertically downwards with a normal toothbrush. In the bow and Molar tooth area is only by crossing the handle over the Incisors is moved, a sometimes laborious brushing possible. A Gum massage does not work and remains without the necessary blood circulation effect completely out.

Due to insufficient cleaning, food residues and toppings remain in the Interdental spaces back, which ugly and painful dental diseases promote. Inflammation on the tooth hems and on the tooth necks occur with the Onset of gum disease and immune system disorders. Open Bleeding gums are the result of which tooth loss is preprogrammed!  

All-round cleaning and all-round massage is not possible with normal toothbrushes feasible, since the inside of the entire dental area is very difficult to reach. It is imperative to brush and massage the entire oral area to be able to achieve. According to the anatomical conditions, only a new idea can achieve the desired effect with a brush to remove this known Problems caused by brushing, which dentists demand. Many dishwashers Details given in the dental field, but without brushing is the care of the Gums imperfect with the complete tooth retention system.

It is desirable to have a massage and cleaning in the complete dental area with one Brush that with freedom of movement of the bristles and the brush body all around Gums reached with the interdental spaces, with the brush head in Adapts the elastic shape of the tooth and gum contour from two sides if possible. The Freedom of movement of the brush body with the bristles is combined so that all details of the Chewing and tooth retention apparatus, including all teeth with the different Areas and contours are to be recorded.

Such a brush is not known from the prior art.

According to the state of the art there are brushes with two or three cleaning heads for the Teeth, but not a gum massage brush that gently wraps around the gums Interdental spaces are reached and teeth are cleaned at the same time.

A number of patents disclose toothbrushes that are for two-sided use on the teeth, but not for gum massage with simultaneous Teeth cleaning. The gums are not reached and on the tooth necks cut and seriously injured. The transition from the handle to the Bristle-carrying legs with the handle locks when pressed down Gums by hitting the top of the teeth a downward or Upward movement and the gums remain unmatched. There is no injury out.

DE 25 05 803 C3: A forked part with curved legs is included Bristles. The bristles are cut at an angle before the legs are unfolded, so that after folding it on the central axis of the handle to a narrow narrow Gap comes in the form of a wedge between the two bristle fields.  

DE 26 08 532 C2: Thighs and bristles are in the form of diamonds that are opposite and in between an application gap in the form of a narrow wedge surrender.

You can also place bristles at different angles in the prefabricated handle insert to also form the narrow application gap in a wedge shape. There is on the X-Y axis an arc on the stem part for freedom of teeth, being at the rear end mechanically moving drive or a handle part is to be coupled. However, the When moving, a too large rash that is felt in the mouth.

US 4449 266: This brush has an inclined handle and angled cut Bristles.

Obliquely cut bristles are not suitable for burr-free rounding because of the oblique interfaces of the round body of a single bristle razor-sharp edges arise that cannot be rounded off.

To design the complete brush head elastic, is in DE 37 03 288 A1, with the Adjusting the brush pressure for hand and mechanically moved toothbrushes proposed, but without significantly changing the wedge gap.

A second obtuse angle opens the wedge gap on the attachment and application side. The brush pressure is adjustable, with the means that one on the middle of the handle long slot is located on an elastic ring at the front end of the brush a compression of the application angle works. Between the handles on the handle there is a guide pin that can be set up by hand in the longitudinal direction of the brush is. The brush pressure can be weakened or strengthened by hand with finger pressure. This adjustability of the brush pressure has not met with approval because of the Adjustability has led to uncertainty. Nor is this brush for you Apply gum treatment. The obtuse second angle at the wedge gap leads to the addressed injuries to the gums with the tooth hem. The close one Wedge gap with the obtuse angle is unsuitable and does not reach the gums. The bristles cannot be rounded off either.

A heat treatment of the bristles from patent DE 34 33 7C3 C1 is disclosed a mushroom-shaped thickening of the trimmed bristle ends. For rounding and The bristle ends are mushroom-shaped and thickened using hot air or a laser beam melted to give shape.  

Also worth mentioning is US 3067 447. The brushes are like a pair of tweezers Brushed bristle heads accessible from two sides for the teeth. The However, the bracket-shaped handle part is not for an even gum massage suitable because there is no freedom of movement in the mouth, with an even Brush pressure, because the large clamps hinder any action.

The brush according to US 2,077,392 locks and obstructs the handle position on the Axis g to h with the double brush head closed above a gum massage total.

In order to perform a perfect oral hygiene and massage, it is necessary to use new means and details of a design, based on the current state of knowledge, to develop a massage brush for the gum treatment, here with the Start improving oral care. If the tooth retention system is in order, too the teeth are not at risk.

The so-called visible and invisible jaw sides in one application Reaching the bristles all around is the goal in design and development. It also enables the teeth to be brushed and cleaned at the same time by guiding the bristles on the teeth. A guide of the bristles on the Rows of teeth are required for gum massage anyway. Judging by the Tooth height from the circumferential occlusal surface of the molars and the cutting edges of the Incisors, the hem of the teeth begins after about half a centimeter Gums. Teeth and gums together have a total height of approximately 2 cm a. To cover the entire area all around and brush with To reach bristle bundles, the mouth of the brush body edges and the Handle covered completely without interference and without bumping. Gums, teeth and interdental spaces should only be contacted by the bristles. So it's one absolute freedom of movement in the mouth required by the shape according to tooth - and jaw models and through direct testing by test persons with several Variants to be determined.

The invention has for its object a complete all-round massage Dental area with a simultaneous cleaning down to reach the teeth practical handling and good performance without being complicated. The bristles should the entire dental room with teeth and tooth necks literally  wash around so that all food particles and bacteria are removed for the best Activation of the gums for better blood circulation of the whole Tooth retention apparatus.

This object is solved by the features of claim 1.

An overlapping part consists of handle and handle with two bristle-bearing Thighs that extend over the teeth to the gums. The two Bristle-bearing legs are evenly branched, with a parallel one Distance to the central axis, approximately U-shaped, with the bristle bundles opposite and form between them an angle of application that extends to the application side on both sides Gums open more and on the narrowing side of the angle to the teeth is less open on both sides. On the largest open side of the Application angles are bristle bundles made of soft bristle material for the Gums and the interdental spaces and harder bristle bundles on the teeth facing closer side of the application angle attached. The self-employed Guidance according to the jaw and the course of the rows of teeth is performed by the teeth in the narrower application angle range adopted.

The bristle ends are rounded and smoothed. Rounding off the individual Bristle ends are state of the art from Boucherie in Belgium. Through a Cutting the hemisphere at the bristle end and using a fine grinding of the spherical shape the best result is achieved at the moment, which is optimized by post-treatment has been.

A new type of clamping device for the machine has been developed, which causes jamming the clamped brush body for pulling in the bristles and rounding off the bristles allows the right and left bristle field of the two legs daring and rotating tools to get to the double brush body. The after-treatment of the bristle ends with a smoothing is new and is done by a with heat applied melting at the rounded ends of the bristles at Slide the bristle-tipped body with the rounded ends of the ground bristles past glowing threads that are at a distance from the Bristle field ends are attached and radiate heat in a controlled manner. The apparent fine Flowing of the bristle material causes an excellent smoothing of the bristle ends without to change the spherical shape of the bristles, because the last grinding marks disappear and  a smoothing is visible and noticeable for the user of this brush, because there is no more cutting or spiking on the gums and between the teeth.

To the bristle fields with the bristle ends left and right to the desired one Direct massage contact and for cleaning on gums and teeth, are the bristled legs from the horizontal movement axis, which from Handle seen with the handle, which is guided over the teeth, inclined.

The bristle-covered legs are thus branching on the two webs left and right with another angle, so that from the branching go out two more angles per side. Both angles, the application angle with the so-called angle of attack per side, bring in the bristles with the bristle arrangement Action if they hit the gums with the surrounding gums. At the same time, the entire area from the upper tooth edges to the Gums end covered, without the bristle-bearing legs for the entire area to have enlarged. A bristle arrangement in the form of a hexagon, with a larger distance, which is related to the central bristle on the angle beam a further range of movement of each bristle bundle, so that the bundle due to the two angular positions of the legs during actions on the handle semicircular movements around the point of bristle fixation in the thighs perform.

The shape of the legs further provides the relationship to the freedom of movement of the Bristle bundle on the double head by the circumferential edges of the legs correspond to the drilling pattern of the bristle arrangement of a hexagon shape and connect these with the transitions in the form of a radius to the handle on the handle. By the hexagon shape of the bristles introduced results on the front Leg ends a further two angles, those in the molar area and on the jaw arches yet another freedom to move through a corresponding one Tilt the brush, pretend.

It is also good to adjust the two legs for the purpose of springing open the two-part head at the branching on the middle of the stem with a slit or The double head, which is open on the tooth side, is cut on both sides The gum side opens further when depressed, as this through the Application angle of the two opposing bristle fields is predetermined to  on the gums all around and on the teeth all around the bristle bundles and to let it work freely.

An embodiment is shown in the drawing.

It shows the Figure 1 in top view of the injection molded handle portion 5 with the continuation of the stem, the board 10. the slot or incision 15 which merges with two webs into two bristle-carrying legs 1 and 2 ; the angles 7 of the axes 8 which branch from the intersection 6 , from the central axis 4 , to the left and right in the stem region of the plate 10 ; the central bristle bundles 14 on the axes 8 , around which further bristle bundles 3 are arranged in the form of a hexagon; the intersections of the bristle arrangement in hexagon shape, with a circumferential edge that defines the shape of the legs 1 and 2 , the bristle bundles 3 are thicker bundles, preferably 2 mm thick and introduced at a greater distance from one another. The bristle bundles 3 facing the center and movement axis 4 (marked as a full circle) are made of harder bristle material, the other bristle bundles 3 located on the axis 8 and below the axis 8 are made of softer bristle material. Furthermore, the tangent circles 23 and 24 , the connection radii of the webs thus formed on the stem of the circuit board 10 to the legs 1 and 2 can be seen; also the folding axes 12 with the spacing 13 for later folding of the legs 1 and 2 , according to FIG. 4, when the bristle bundles 3 are introduced and finished for rounding and smoothing each individual bristle according to FIG. 8.

Fig. 2 shows the brush in folded form, seen from the top view with the two bristle-covered legs 1 and 2 in the parallel plane, left and right at the same distance from the central axis 4, the folding axes 12 with the distance 13 ; also the incision or slot on the central and movement axis 4 , with a point 29 which can be detachably connected with handles 5 of different sizes. Children need smaller handle sizes, adults need larger handles 5 . Furthermore, the bristle bundles 3 can be seen in the double head on the inner surfaces of the legs 1 and 2 and how they appear in the hexagon arrangement after folding.

. The Figure 3 shows the brush in abgefalteter shape from the side view in the ascending and truncated representation with the right leg 1; the axis 8 of the angle 7 , based on the intersection 6 of the stem piece from the board 10 with the clearance angles 19 , 20 and 25 from the vertical 21 based on the application side 30 ; the clearance angles that emerge from the bristle arrangement in a hexagon shape from the axis 8 at an angle 7 with a peripheral edge from FIG. 1 and are thus repeated for a desired freedom of movement.

FIG. 4 shows the folded double-headed in the form of a more open U uniformly to the left and the right seen from the center axis 4, with the angles 16, the distance 13 the two-fold axes 12, to the application angle 17.

Also, the folding path 18 on both sides of the legs 1 and 2 from the circuit board 10 is shown visibly, as well as the bristle bundles 3 , which are made of soft bristle material at the application angle 17 on the largest open side and for the bristle material which is harder on the side of the application angle that becomes narrower (such as fully filled) is used for use on the upper jaw.

FIG. 5 shows a brush in the top view seen with a small handle 5 for children, with a releasable point 29.

The handle 5 or the handle 10 can be exchanged for another handle 5 at the detachable point 29 . Sizes or handle thicknesses on the double head are to be adjusted according to the hand-guiding conditions of the people, larger handles for adults, smaller handles for children. A fixed seam connection between the handle 5 and the handle 10 can also be created in the injection mold by dividing the mold plates

FIG. 6 again shows the brush as in FIG. 5, but the detachable point 29 is joined and the handle 5 is extended by coupling a further handle 32 for the purpose of an all-purpose brush. A complete brush with handle, handle and double head can be used again by another handle to clean related devices with edges and edges, etc. B. lines, chains and sprockets and other uses, based on the double-headed principle also in other size ratios.

FIG. 7 shows the view from FIG. 4, the double head turned through 180 ° for use on the lower jaw, and again the folding axes 12 with the distance 13 from the application angle 17 .

FIG. 8 shows an enlargement of individual bristles from a bundle as they are smoothed in a rounded manner centered on the central axis of the bristles at the bristle ends 27 by melting on the rounding 28 by means of filaments.

According to FIG. 1, a shaped handle part 5 is shown with the continuation to form a handle, the circuit board 10 , which merges with the slot or incision 15 into two individual bristle-carrying legs 1 + 2 . For this purpose, a plastic part is injection molded in a mold, or sawed out or punched out of plate material.

Here, the shape for freedom in the oral cavity and the effect of the bristles for freedom of movement are predetermined with three axes, firstly by the axis of movement on the center 4 and twice by the inclined axes 8 , in relation to the axis of movement.

From the center 4 , the axis of movement of the handle 5 with the continuation to the handle, this branches into two identical transitions to the two bristle-carrying legs 1 + 2 , which are inclined.

Starting from the intersection 6 , in the stem area, the two oblique axes 8 begin, which branch to the right and left in order to fix the angular position 7 of the bristle-bearing legs 1 + 2 with the central bristle bundle 14 . The shape of the legs, the transitions from the bristle-bearing legs 1 + 2 , to the two webs for connection is formed by two tangent circles each with the radii 23 and 24 . Further bristle bundles 3 are arranged around the central bristle bundle 14 in the form of a hexagon. The bristles, which are located on the axis 8 and the center and which face outwards, consist of soft bristle material and the bristles which face inwards and point to the angle 7 are made of hard bristle material. (The hard bristles are marked.)

This shows that there are soft bristles on the plane facing the gums and there are hard bristles on the plane facing the teeth. The peripheral edge of the legs 1 + 2 in the form of a hexagon is determined by the hole pattern of the bristle field, which also relates to the bevels for freedom at the leg ends, the leg width. Furthermore, the two axes 12 are shown with the distance 13 for the parallel folding of the legs 1 + 2 , after the central axis 4 , when the punching in of all bristles 3 , hard and which bristle bundle, with the rounding and smoothing 28 , is completed at the bristle ends . The bristle bundles are preferably 2.5 mm thick. By means of heat treatment by pushing the unfolded brush bodies, with the bristle ends 27 at a fixed distance from glowing wires, the rounding 28 after cutting and grinding is smoothed by a slight melting of the remaining grinding marks on the hemisphere profile, as shown in FIG. 8 on sheet 2 , shows.

Many bristles also form thicker bundles, as is the case with known toothbrushes is not the case. The bristles arranged in this way have a very good stability, do not bend and take up a large range of motion in the lateral and angular moving a. The opening angle of the double head with the angle of attack The double head forms two angles at the same time, the gum contour and the Teeth with an almost constant bristle pressure with good freedom of movement cause a resilient balance. The resilient compensation is through the slot or Incision made at the fork branch point in the middle of the movement axis. Depending on Slot length causes a more or less resilient compensation.

According to FIG. 2, the brush body from FIG. 1 covered with bristles, viewed in plan view, is folded parallel to the central axis 4 in the form of an open U to the left and right. The folding axes 12 are softened from the middle of the handle from the right and left side depending on the type of plastic, which is necessary, for example, with heat, warm air, ultrasound or by chemical solvents in a certain time unit. The finished shaping of the softened legs 1 + 2 is carried out by hand or by means of a device or with the mechanics of an automation, as can be seen from the view against the double head according to FIG. 4 with the angles 16 , in a U- Shape on the folding axes 12 , with the distance 13 , on the way of folding 18 , the legs 1 + 2 , to the application angle 17 . The bristles 3 with the flat bristle field, the rounded bristle ends, are parallel to the legs in the open application angle 17 . According to FIG. 3, the folding axis 12 and the axes 8 beginning at the intersection 6 and the recurring angle 7 from FIG. 1 can be seen in side view in partial section on the double brush head. The angle 7 is the angle of incidence of the bristles 3 to the two active sides for gums and teeth, with the relief angles 19 , 20 + 25 to the application side 30 , at right angles to the vertical 21 , to bring about freedom of mouth in the arch area of the upper and lower jaw.

An all-round massage of the gums in the entire dental area, on the Tooth necks and the spaces between the teeth with the tooth hems is reached.

At the same time, by guiding the bristles on the rows of teeth for the gums achieved good practical handling, with the teeth with the interdental spaces immediately brushed all around. The most gentle, effective and The complete massage with tooth cleaning takes place smoothly  soft and hard bristles that are rounded and smoothed at the bristle ends. Of the User is forced to leave nothing in the oral and dental room in need of care omit.

The bristles literally wash around the teeth, the gums and the teeth what is caused by the angle of attack in the application angle of the bristles and that Impact of the bristle ends on the contours to be brushed. In a bundle as well also individually, the bristles jump from tooth to tooth to in the interdental spaces up to the tooth hem with the beginning gums a cleaning and To achieve massage effect.

Passed over the teeth with a hand movement with the brush axis of the Handle on two axes of the angle of attack with an adjustment and spring-back linear and circular crank movements on the complete tooth and jaw contour.

All figures of perfect dental hygiene and gum massage can be imagined run easily. A slight tilting of the double head over the vertical tooth axis increases or decreases the massage pressure on the gums with a simultaneous Increase or decrease brush pressure on the tooth surfaces when the occlusal surfaces can be brushed after a turn of 85 ° to 90 °. Not just a spring open Compensation takes place from the slot of the double head, but also a mutual Interlacing both bristle-covered thighs is visible when on tooth and A test to determine all the effects is made so that the jaw models Solution of the task becomes visible. With the same recognition, it is clear in this test that with a germ-free brush, by antiseptic agents, also bacterial and fungal colonies must be removed from the dental area all around.
