Definitions
- the invention relates to a toothbrush for dental prostheses, consisting of a handle and an adjoining bristle holder which is convexly curved and is provided with cleaning bristles on its convex outside.
- Denture wearers or wearers of orthodontic regulation braces generally have the problem of cleaning the denture or brace. This problem is particularly difficult for people of advanced age, the visually impaired and those with movement problems. Cleaning is particularly difficult for all prosthesis wearers on the go, e.g. B. in the restaurant, where it is important to carry out the cleaning quickly and unobtrusively.
- the prior art also includes a cleaning set for dental prostheses, which is accommodated in a portable case and which, among other things, comprises brushes of various types.
- This brush set also includes the brush according to the preamble of protection claim 1 of the present utility model avoidance.
- this previously known toothbrush with a convexly curved bristle carrier is not suitable for reliably and quickly cleaning all the problem areas of dental prostheses or braces, such as narrow cavities, depressions, channels or the like. This results from the fact that this previously known brush is only part of a brush set, the individual brushes of which are each adapted to certain functions when cleaning prostheses. It is an object of the invention to develop the toothbrush according to the preamble of protection claim 1 in such a way that a quick and reliable cleaning of all problem areas of dental prostheses or braces is possible with a single toothbrush.
- the invention proposes, starting from the toothbrush of the type mentioned at the outset, that the bristle carrier has the shape of a spiral with a radius of curvature decreasing towards the outer end and that the bristles support the bristle carrier transversely to the curvature plane of the spiral on both sides tower over.
- the special shape of the bristle holder and the arrangement of the bristles make it possible to use the differently shaped areas of the brush head for the cleaning work, with the handle being in an appropriate position. In this way you can also use this toothbrush to comfortably clean the problem areas of dental prostheses listed above. Since the bristles project beyond the bristle carrier not only to the outside but also to the sides, the bristle carrier is guided by the bristles when penetrating into openings, cavities or grooves in the prosthesis and held at a distance from the surfaces of the prosthesis. This has the particular advantage that during cleaning work in the area of channels, hollows or openings, essentially only the cleaning bristles but not the bristle carrier come into contact with the prosthesis.
- An expedient development of the invention provides that the cross-section of the bristle carrier is rounded off approximately semicircularly on the side covered with bristles and that the bristle ends lie on a circular or elliptical arc in each cross-sectional plane of the bristle carrier. This results in a largely uniform cleaning effect in all conceivable positions of the handle.
- the length of the bristles running transversely to the plane of curvature of the spiral towards the outer end of the bristle carrier gradually decreases over its length. This makes it even better possible to penetrate the narrow end of the prosthesis or brace with the outer end of the brush head.
- the pole point of the spiral lies at the height of the longitudinal axis of the handle.
- the curved areas of the spiral project beyond the handle of the toothbrush on both sides in the plane of curvature of the spiral.
- the first section of the brush head adjoining the handle is only slightly curved and is more suitable for cleaning the large surfaces and flat arches of the prosthesis.
- the protruding part of the brush head protruding to the other side is more for the problem areas discussed above
- Suitable for prosthesis By turning the toothbrush by 180 ° around the longitudinal axis of the handle, one or the other area of the brush head can be used Bring effort.
- the bristle carrier in the transition area to the handle is curved opposite to the curvature of the spiral.
- the length of the bristles in the transition area towards the handle gradually decreases. This creates an optically appealing transition between the handle and the long bristles of the brush head.
- the handle on its end facing the bristle holder is provided with two opposing recessed grips, the surfaces of which run perpendicular to the plane of curvature of the spiral.
- FIG. 1 shows a toothbrush according to the invention in a side view
- FIG. 2 shows the toothbrush according to FIG. 1 in a top view
- FIG. 3 shows a section along the line III-III in FIG. 1.
- the handle of the toothbrush is designated by the reference number 1.
- the handle 1 has two opposing recessed grips 2 and a NEN tapered end portion 3.
- the handle 1 merges into a bristle carrier 4, which has an approximately semicircular cross section and, in a side view (FIG. 1), has approximately the shape of a spiral with a radius of curvature that decreases over the length.
- the pole point of this spiral lies approximately in the extension of the longitudinal axis of the handle 1, such that the weakly curved area of the spiral in FIG. 1 lies above the longitudinal axis of the handle 1 and the more curved area of the spiral lies below this longitudinal axis.
- the convexly curved outside of the bristle carrier 4 is covered with bristles 5.
- These bristles 5 run approximately perpendicular to the surface of the bristle carrier 4 and project beyond the bristle carrier 4 transversely to the plane of curvature of the spiral on both sides.
- the ends of the bristles 5 lie in relation to each cross section of the bristle carrier 4 approximately on an arc of a circle or an ellipse (cf. FIG. 3).
- the length of the laterally projecting bristles 5 gradually becomes smaller towards the end of the bristle carrier 4, so that the end of the brush head 4, 5 can better penetrate narrow cavities or grooves in the prosthesis.
- the length of the bristles 5 gradually decreases toward the handle 1, so that there is a visually smooth transition between the handle 1 and the brush head 4, 5.
