Definitions
- the invention relates to a toothbrush with a handle, a head designed as a housing which is open at least on one side, a brush part which can be inserted in the open side thereof and has a carrier and bristle trimmings and with latching means inside the housing and on the carrier for fixing the brush part, the housing a cheek supporting the carrier in the region of its periphery and furthermore means are provided on the head for the tool-free pressing out of the brush part from the rear of the head.
- Eursten are known (US 403 350, US 1 148 566, US 1 711 621, US 2 326 632), in which the brush part with the bristle trim is subsequently inserted into the actual brush body. This often happens for manufacturing reasons and especially when connecting the bristle bundles directly to the brush body, for example by thermal processes such as welding, injection or the like. not possible.
- Embodiments are also known in which the brush part can be detached from the brush body and exchanged for another (GB 1932/1910). For toothbrushes, the above-mentioned embodiments are not or only insufficiently suitable.
- Toothbrushes are needed far more often than all other types of brushes. The reason for this is the frequent use for proper dental care (up to three times a day) and the resulting rapid wear. In addition, the toothbrush should be replaced even with relatively little wear, which would be acceptable with other brushes, in order to always ensure optimal effectiveness.
- toothbrushes are intended for use by people of all ages and levels of education must be, so that the replacement of the brush part must be possible in the simplest way and with little effort while at the same time sufficiently secure connection of the parts.
- the bristles are fastened to a carrier in the form of a thin plate and this brush part is interchangeably locked in the frame-like or housing-like head (DE 30 38 895, 37 24 640).
- the carrier has strip-like catches on its peripheral surface and the housing has corresponding groove-like depressions.
- the carrier has on its back a pin which engages in a hole in the bottom of the housing and forms an exposed pressure surface on the back of the head. The carrier is snapped into the head and can be ejected by pressing on the pin.
- the plastic mass to be exchanged when the bristles wear out is reduced to a minimum and the exchangeable brush parts can be manufactured inexpensively due to the low use of materials.
- the carrier has already been provided with a circumferential elastic edge on its bristle side (DE 37 24 640 C2), the back of which should lie tightly against the end face of the housing cheek.
- This requires corresponding tensile forces that pull the carrier into the housing, and thus correspondingly large locking forces. This in turn complicates the insertion and ejection of the brush part.
- the locking means Since the locking takes place by positive locking, the locking means must have a correspondingly large volume, which requires large wall thicknesses on the head. different.
- Even more complex is an embodiment (DE 296 00 398 Ul) in which elastic flat seals are inserted on all sealing surfaces between the carrier and the housing, which at the same time hold the brush part by means of a correspondingly high preload. The pretension must be completely absorbed by the housing cheek, which inevitably widens after a short time and no longer guarantees a secure hold of the brush part.
- a very stable and permanent connection of the brush part and head results in a known toothbrush (DE 41 04 314 AI) in that at the back of the Carrier two V-shaped strips are formed, which run over the entire length of the carrier. These engage in a corresponding V-shaped opening on the head opening, which also runs in its longitudinal axis over the entire length.
- the elastically deformed parts of the snap-in connection are therefore located on the interchangeable part where the material fatigue is less important.
- the invention has for its object to design a toothbrush of the aforementioned construction so that the special hygienic requirements are met and the Performance characteristics are improved.
- the mutually abutting surfaces on the cheek of the housing and on the periphery of the carrier are designed as completely smooth-walled sealing surfaces and the latching means have resilient latching lugs which are offset inwards relative to the sealing surfaces and which in a space between the bottom of the housing and the back of the carrier facing it.
- a major advantage of the invention is that the functions "sealing" and "locking" are structurally separate.
- the smooth periphery on the beam and the equally smooth contact surface of the cheek are the prerequisites for these surfaces to lie perfectly against one another. This can be supported by a slightly conical design of these surfaces.
- Due to the design of the locking means as resilient locking lugs outside the sealing surfaces the cheek of the housing is not pretensioned by the locking and holding forces and it cannot come to cold flow there, so that it can fulfill its sealing function over a long time. Cavities, gaps, etc. are thereby largely avoided so that the toothbrush dries quickly after use, as desired, and thereby prevents bacterial nesting, as well as the accumulation or storage of dental care remnants, etc. is avoided.
- the resilient latching lugs on the one hand ensure reliable locking, but on the other hand also make replacement easier.
- the outer contour of the toothbrush in the area of the head can be optimally adapted to the Adapt the intended purpose, that is to say, for example, to ensure rounded, smooth-surface contours in order to avoid injuries in the oral cavity during dental care, and on the other hand the resilient locking lugs are arranged in an area in which their dimensions are not restricted by other structural conditions. They can be designed so that their functional reliability is maintained over a long period of use. Furthermore, the entire thin-walled cheek of the housing is kept free of tension.
- the arrangement of the locking means on the one hand and the pressure surface provided for loosening on the other hand ensure that the brush part does not come off prematurely, since the pressure acting on the bristles during use cannot lead to the loosening of the latching, rather a targeted, albeit low, pressure on Back of the head is necessary.
- the easy interchangeability of the brush part promotes the use of this system by the consumer, especially since it is possible to use brush parts with bristles of different hardness and arrangement.
- the resilient latching lugs are formed on the bottom of the housing so as to protrude inwards and cooperate with depressions which are formed on the back of the carrier.
- An advantageous embodiment is characterized in that the housing has a through opening on its bottom forming the back of the brush head, the wall of which is at least partially extended inwards to the resilient latching lugs and in that the carrier has a pin engaging in the through opening whose end face forms an exposed pressure surface for pressing out the brush part or cooperates with a pressure surface on the housing.
- the through opening with its sleeve-like wall fulfills several functions. On the one hand it can guide the pin arranged on the support, on the other hand at least part of its wall serves to form the resilient latching lugs, that is to say for positioning and fixing the support.
- the through opening gives the possibility of forming the pressure surface on the back of the head.
- the pin If the pin is guided on the wall of the through opening, it has on its circumference the depressions into which the latching lugs on the housing deflect from the outside.
- the peg forms the pressure surface with its exposed end face, it advantageously protrudes a little from the contour of the housing at the back of the head, which signals its function and the pressure to release the latching can be easily applied.
- the aforementioned embodiment has the advantage that the toothbrush consists of only two components, namely the handle with the head forming the housing and the brush part with the carrier and the bristles.
- the toothbrush can therefore be manufactured easily and economically.
- a design that is somewhat more complex in terms of production technology, but equally advantageous in terms of use, is characterized in that the pin is arranged in the through opening at a distance from its wall and the carrier has recesses extending beyond the resilient locking lugs on the outside.
- the through opening at the back of the head is preferably closed by a pressure plate forming the pressure surface, which lies against the inside of the end face of the pin.
- the printing plate forming the printing surface can be made of a rubber-elastic material, e.g. consist of an elastomer and subsequently inserted at the opening edge of the through opening and, for example, fixed to the wall of the opening by latching or molded onto the opening in the in-mold process.
- the pressure plate is elastically deformable at least to the extent that when pressure is exerted on the pressure plate, the path necessary for releasing the carrier is covered. The pressure is transferred from the pressure plate to the pin, so that the carrier is displaced in the pressure direction and the detents are released.
- the pressure plate can be an integral part of the head and can be connected to the rest of the housing either by a correspondingly thin wall thickness of the head in this area or by a resilient wall section.
- cover plate is a one-piece, but resilient part of the head, it can further be provided that the latching lugs are formed on the side of the pressure plate on the bottom of the housing and from which the carrier defines between them Locking position can be spread by pressure on the pressure plate with the release of the carrier.
- the resilience of the locking lugs can be achieved in practically any plastic by a certain length of the locking lugs, whereas the housing can be dimensionally stable. Nevertheless, thinner wall sections on the back of the head make it possible to achieve spring properties in order to make the pressure plate forming part of the housing movable with a limited stroke. Furthermore, such resilient wall sections can be formed in the area of the attachment of the spring lugs to the housing, so that when pressure is exerted on the pressure plate, their displacement at the same time causes the latching lugs to spread and the carrier is released from the latching and can fall downward.
- the cheeks completely or partially overlap the outside, a complete overlap with the flush connection of the outer surfaces of the beam and cheek being advantageous in order to avoid corners, niches or the like.
- the wearer can also lie against the end face of the cheek and lie flush with the outside thereof. This creates an additional sealing surface.
- This embodiment also has no niches or steps that would promote the formation of dirt.
- the carrier has a circumferential edge on the side opposite the bristle trim, with which it engages over the cheek on the outside.
- This embodiment has the advantage that the carrier forms a closed surface not only in the area of the bristle trim, but also on the sides of the head. 7/49314 PC17EP97 / 03207
- Both of the above-mentioned embodiments have the advantage that the greatest possible number of bristles can be arranged on the carrier for a given outline of the head.
- the inventive design of the housing further gives the possibility that the carrier consists of an elastomer and seals against the cheek. This can be supported by sealing lips.
- the inventive design of the housing ensures that the cheeks clamp and compress the elastomer carrier like a frame. Increased frictional forces also occur in the area of the sealing surfaces. This will avoid gaps.
- the bristles are resiliently mounted with their ends located in the carrier.
- the printing surface can be optically lifted from the rest of the housing by the design of the surface, in order to indicate to the user the function of the printing surface.
- This visual highlighting can be achieved through appropriate profiling, different types of material, coloring or the like. respectively.
- the housing can have a soft elastic coating as a mucous membrane at least in the area of the cheek. have protection.
- the latter can additionally cover the end face of the cheek and bear with its inner edge in a sealing manner against the peripheral surface of the carrier.
- the latching means are no longer arranged on the cheek of the housing, but instead only perform guiding and sealing tasks, they can be thinner-walled than the known embodiments. Conversely, this allows the carrier area and thus the number of bristles or bundles to be increased.
