Description

SUBSTANCE: invention relates to medicine and can be used in toothbrushes for more convenient and precise fixation of the toothbrush in the user's hand during brushing.

The toothbrush is the main tool for cleaning teeth and consists of two main elements: bristles, with the help of repeated movements of which cleaning of different surfaces of the teeth and a handle, which is held by the hand.

In turn, two elements stand out in the handle: the part of the handle that is held by the index finger and thumb - the grip, and the lower part of the handle that is clamped by the little finger and the bottom of the palm.

Currently, there are several main types of toothbrush handles with different types of grips and bottoms, but in general, there are primarily several types of grip:

- Flat grip, where the section of the handle at the grip point is one or another type of rectangle (see https://pearl-smile24.ru/curaprox-cs-5460-ultrasoft-zubnaya-schetka-s-ultra-myagkoj-schetinoj. html; https://happy-smile.com.ua/zubnye-schetki/zubnaja-schetka-curaprox-ultrasoft-kuraproks-5460-schetin);

- Square or diamond grip (with appropriate section) (see https://health-shop.com.ua/uk/doglyad-za-rotovoyu-porozhninoyu/171-zubnaya-sshetka-gum-technique-pro-compact-soft -myagkaya.html);

- Oval grip (with the corresponding section of the handle)

All known grips on toothbrush handles, despite their diversity, are symmetrical about the axes of the handle for ease of use by both right-handed and left-handed people. On many toothbrushes, the handles of the grip surfaces are covered with rubberized inserts for a comfortable grip.

When brushing teeth, a person in the vast majority of cases uses one hand and cleans several parts of the surface of the teeth (see Fig.1).

For the right-hander (for the left-hander mirrored) figure 1 shows:

In Fig.1: 1 - thumb, 2 - index finger, 3 - brush direction, 4 - toothbrush handle.

In the manufacture of toothbrushes, the problem is, in particular, to create an ergonomic toothbrush that "feels good in the hand", and, in addition, the toothbrush must be easy to maintain, be held securely during use, have an impeccable, pleasant feel. surface, i.e. the user must simply "willingly pick up" the toothbrush.

During the process of brushing the teeth, the grip of the pen (the position of the fingers and hand on the grip of the pen) may change several times. At the same time, the main method of fixing the pen in the human hand is to clamp the pen with the index and thumb and little finger and the lower part of the palm. The position and angles between the surfaces of the pads of the thumb and forefinger depend on one or another grip of the handle, as well as on the length of the fingers and the location of the joints on them. Depending on which part of the tooth cavity is being cleaned, the position of the fingers on the grip of the toothbrush handle changes. Based on habit, usually 5 to 9 grips of the pen are used in the process (some are repeated when brushing different parts of the surface of the teeth).

Thus, there is a wide variety of finger and hand positions on the handle of a toothbrush, depending on the user of the toothbrush. But the most important circumstance is the fact that most of the positions are at various oblique angles, which implies an asymmetric location of places (stops) on the grip, where the fingers touch the handle. Fingers most often squeeze the handle not in those places that are intended to be gripped, but on the edges of the handle at different angles. In the process of cleaning, the position of the handle in the hand often changes, it also becomes moistened, and the convenience of holding it and fixing the grip depend primarily on the functionality of the shape and configuration of the grip.

Given the above, the most effective, therefore, is an asymmetric grip, which allows you to provide a comfortable and tight any grip on the handle when cleaning different parts of the tooth surface. The number of grips should correspond to one or another number of pads on the grip, located asymmetrically, which allow for the tightest possible application of the fingertips to the surface of the toothbrush handle. Stops can be either explicitly highlighted, or just part of the surface of the handle of an asymmetric shape. Based on this, the grips can be with a different number of stops or simply in the form of an asymmetric composition relative to the axis of the handle, depending on the preferences of users.

The closest analogue is a toothbrush according to patent RU2433771, publ.: 11/20/2011, which contains a head area, cleaning elements, a handle area and a neck area connecting the head and handle areas to each other. The toothbrush is made of a first plastic component and at least one additional second plastic component, the first component having a relief structure coated with the second component. The relief structure contains high areas with the shortest distance to the outer surface of the second component and low areas with the largest distance to the outer surface of the second component. The relief structure contains, adjacent to the high and low sections, sections of intermediate height, the distance from which to the outer surface of the second component is between the distances from the high and low sections to the outer surface. The second component is made transparent or translucent. An embodiment of a toothbrush is provided. The invention is aimed at improving the quality of the toothbrush.

The prototype contains pads on the grip of the handle, which allow the application of the fingertips to the surface of the handle of the toothbrush.

The technical problem of the prototype is that the location of the stops is symmetrical, which does not provide any comfortable and tight grip of the handle when cleaning different parts of the tooth surface.

The technical result of the invention is the expansion of the arsenal of technical means, as well as the implementation of the handle of the toothbrush in the form of an asymmetric grip, which allows for a comfortable and tight grip of any handle when cleaning different parts of the tooth surface.

This technical result is achieved due to the fact that a toothbrush with a head area with cleaning elements, a handle area and a neck area connecting the head and handle areas to each other, the toothbrush being made of plastic, the handle area provided with embossed finger stops, moreover the relief structure contains inclined, largely flat surfaces forming sections of intermediate height, characterized in that the relief stops for the fingers are made around the entire handle and extend in the longitudinal direction to the lower end of the handle, and the planes between adjacent stops at the same height of the handle are located under different angles relative to each other and form internal angles between themselves from 120 to 171 degrees, and the position of each stop in the longitudinal direction of the handle changes.

Preferably, the number of abutments is in the range of 5 to 11 sites.

Preferably, the stops on the handle are arranged in a spiral pattern.

Brief description of the drawings

Figure 1 shows common brushing areas for brushing with one hand.

Figure 2 shows the arrangement of the stops of the toothbrush in the section of the handle at a certain height and examples of how the planes between adjacent stops at the same height of the handle are located at different angles relative to each other.

Figure 3 shows a practical example of a sample toothbrush according to the invention.

In the drawings: 1 - thumb, 2 - index finger, 3 - direction of the brush, 4 - toothbrush handle, 5 - finger rest on the handle, 6 - center of the handle axis.

Implementation of the invention

The toothbrush according to the invention is made with a head region with cleaning elements, a handle region and a neck region connecting the head and handle regions to each other.

The toothbrush is made of plastic, which facilitates its production in a single form according to the invention.

The handle area of the toothbrush is provided with embossed finger rests, the embossed structure comprising inclined, substantially flat surfaces forming portions of intermediate height.

What is new is that the embossed finger rests 5 (see FIG. 2) are provided around the entire handle 4 and extend longitudinally to the lower end of the handle.

The planes between adjacent stops 5 at the same height of the handle are located at different angles (α) relative to each other and form angles from 120 to 171 degrees, and the position of each stop 5 in the longitudinal direction of the handle changes as shown in one of the possible examples implementation of the invention, shown in Fig.3. This example is not the only possible implementation, but in it the stops on the handle are located in a spiral and the number of stops in this example is five sites, which is a minimum angle (α) of 120 degrees between the planes of adjacent stops.

The location of these pads-stops should be at different angles in accordance with the fit of the fingers 1 and 2, by analogy with Fig.1 in known solutions.

The number of pads (stops 5) can be more than five, but not more than 11, since a larger number of pads already reduces the shape of the toothbrush close to a circle with slightly protruding planes.

The example in Figure 2 shows an embodiment of seven stops on a toothbrush handle. From the example in Fig.2 it can be seen that the internal angles (α1, ... , α7) are constantly changing in the range from 120 to 171 degrees, and the position of each stop in the longitudinal direction of the handle also changes.

The values of angles from 120 to 171 degrees are determined empirically. At angles up to 120 degrees, the thrust pads will be too prominent, or the number of thrust pads will be less than five, which does not provide a reliable grip with the fingers. And at angles of more than 171 degrees, the position between adjacent planes will be close to the plane and the finger of the hand will not be able to find the protrusion to rest against it.

These distinctive features of the invention ensure that the handle of the toothbrush is made in the form of an asymmetric grip relative to the axis 6 of the handle 4 of the toothbrush, which makes it possible to provide a comfortable and tight grip of the handle when cleaning different parts of the tooth surface.

Also, such a shape of a toothbrush is not known in the art, which allows us to announce the receipt of a new type of asymmetric handle shape and the expansion of the arsenal of technical means of toothbrushes.
