Description

The invention relates to a tooth and gum massage brush according to the preamble of claim 1, and an essential Part, for making such a brush.

This is a brush, as is known, which instead of a brush head owns two brush heads. The design of this DUO brush is executed so that on a handle or handle at the front end two bristle-bearing legs are arranged in the shape of a more or less unfolded U-profile, face each other in such a way that the bristles attached to the bristle legs in bundles form a gap between them that extends to the application side of the Watching teeth and gums, more like opening 180 degrees has turned the opposite gap side.

The invention has for its object a DUO brush of the input mentioned type even better for the massage of the gums on the upper and To be able to use the lower jaw all around. This also becomes the usual Brushing the teeth allows because this works directly with the gums massage for the necessary blood supply to the gums to hold and teeth locking in the dental room is improved by massage. The known toothbrushes according to Patent No. P 25 05 803.1 and P 26 08 532.5-23, and U.S. Patents 30 67 447 and 20 77 392 are for cleaning teeth from both sides of Vor part, however, for the massage of the gums only the upper edge in the half centimeter range, the so-called tooth hems from the bristles achieved if these brushes are not tilted around the tooth, additionally can. Tilting to the inside gum massage is through Tongue only possible to a limited extent, so that massaging of the inside Jaw area is incomplete. To overcome this disadvantage lifting a DUO gum massage brush was developed, which without Enlargement of the two legs that carry the bristle trim to to achieve complete gums with the teeth developed. A complete cleaning of the teeth is without the gum massage without Disability fully guaranteed without the volume of the brush longer or wider leg of the brush was enlarged.

The object is achieved by the invention in the marked part of claim 1, solved with the specified means.

Further configurations of the DUO brush, according to the invention, are characterized in further claims 2-3.

As already mentioned, a massage brush for the gums, the so-called inner and outer jaw side in one application can be reached from the bristles. The goal in construct tion and development is also, the teeth immediately by brushing and cleaning with. Measured by the tooth height, from the around running occlusal surface and the tooth cutting edges, begins after about half a centimeter of the gum line with the gums, which occupies a total height of approximately 2 cm. Double around this area tig from the above-mentioned upper or lower edge of the teeth To achieve brushing, this area must be undisturbed by body edges and brush handles are exposed. With double-head brushes that is Handle or handle, in the middle, above these chewing and cutting surfaces arranged and wears the two bristled legs.

Is the bristle stock after a bend or free distance, from Seen from the stalk parallel and is this bristle pattern effectively assigned to the teeth in the horizontal plane to the axis of the stem, so all bristle bundles, depending on the tooth thickness and contour, are in one somewhat equal pretension and adjustment to the tooth and gums in action, but noticeably difficult to move and noticeable on the stem or Handle, so that there is also a pinch through the curve the teeth and the tooth fringe is noticeable.

A bristle pattern that was not arranged in parallel was determined by experiments determined on models, such as a tangent second Axis seen at an angle to the stem axis. The bristle pattern is like this to the stem and the axis of movement at an angle, which is down was adequately articulated to the gums. This results in visible and noticeably the advantage that each bundle of bristles is a better matched one Preserves and allows a larger movement, as this through the Is the laws of wedge action or the laws of angles of force and path.  

So there are two angles, all around on the sides of the Teeth and on both sides of the gums. The first angle is which seen in cross-section, through the two-sided Bristle bundle is specified. The second angle is which one the horizontal movement and stem axis of the handle with two Branches off, in the form of the complete head. The central axis the bristle head, which is inclined, is also the central axis of the Bristle pattern. The bristle field is in shape at the center a hexagon with bristles.

The bristle ends are rounded and their number, many bristles too to form equally thick bundles, such as this in known Toothbrushes are not. The bristles arranged in this way have a very good stability, do not bend and take a big one Freedom of movement for lateral and angular movement. The opening angle of the double head and the angle of attack of the Brush body are two angles at the same time, on the tooth and Gum contour using a different bristle pressure pretend good freedom of movement. A resilient balance is still through a slot or incision at the fork branch point attached to the center of the stem axis. Depending on the length of the slot this causes a more or less resilient compensation.

So that the massage on the tooth hem with the entire gums can be carried out in the most gentle and effective way the bristle bundles on the most open angles, of the application angle made of soft bristle material or weaker material thicknesses, such as the bristles, the less open side of the application angle are attached.

It is the bristle bundles that work on the teeth, harder, like the bundles of bristles that massage and brush on the gums.  

The gum massage brush with two cleaning heads has through the two specified angle on the double head, the opening angle and the setting angle and the thicker bristle bundles, an easy application result in no jamming of the bristles on the gums and the teeth. The brush reaches through the angle of attack with a straight, horizontal grip also the deeper gums area which can be further adjusted by lifting or tilting the handle is. The short leg shape with the different bevels angle at the front end of the two legs, cause greater freedom in the arch area of the upper and lower jaw.

The handle or handle can be countered by a clutch another handle of different sizes or handle thicknesses on the Double head can be exchanged. Larger handles for adults, for Children have smaller grips, according to the hand guidance conditions, or color coding, or the like for users the brushes.

For the purpose of an all-purpose brush, a complete brush with a handle and double head, again by another handle, for cleaning related devices with edges, edges, etc. such as linen and Chains, etc. are used, based on the double head principle.  

Manufacture of the brush

The brush is initially a flat part, made of plastic, which in an injection mold is injected as a so-called circuit board, or from Plates or strips can be sawn or punched out.

The bundles of bristles ( 3 ) are then punched into the preformed or drilled holding holes by means of anchors. The circuit board body ( 10 ) with the stamped-in bristles ( 3 ) is folded on the branched part of the brush body, on a folding axis ( 12 ), to the right and left of the branching to form an angle ( 16 ) which defines the overall angle ( 17 ) , which forms opposite bristle bundles, with the application gap open at the top or bottom.

Preferably two different bristle hardness. Soft on the gum-facing plane. It was hard on the teeth applied level.

The two folding axes ( 12 ), right and left, seen from the top view, run together parallel with the stem and central axis ( 4 ), so that after the final shaping, the angle ( 7 ) specified in the board is at the branching of the bristle-bearing legs ( 1 + 2 ), again results, or repeated with the same angle ( 7 ) from the board ( 10 ).

The folding axes ( 12 ), seen from the center of the handle to the left and right, are softened for folding according to the type of plastic, as this z. B. with heat, warm air, ultra-sound or by chemical solvents, for softening in a unit of time is neces sary so that the finished molding can be done by hand or by means of a device or by mechanics of automation by grippers or baking.

The individual bristles ( 27 ) in the bundles ( 3 ) are rounded off before folding on the two folding axes ( 12 ), after punching into the board ( 10 ), by grinding at the bristle ends.

With subsequent heat treatment and sliding past, at a distance, on glowing wires, the rounding ( 28 ) is smoothed out by melting.
