Definitions

  • the invention relates to bristle goods consisting of a Bristle carrier and bristles attached to this, the are arranged individually or in bundles and their hardness is adjustable.
  • Bristle goods in the sense of the invention are all Products understood that with bristles or bundles of bristles are occupied.
  • the hardness of a bristle is essentially determined by its Length and cross section as well as determined by the choice of material. The selection of the bristle hardness is in turn by determines the intended use of the bristle goods or by the desired function. For brushes for cleaning dirty surfaces as well as for technical ones The main focus is on scratching and brushing, i.e. the bristles must be correspondingly hard (coarse). For brushes for polishing purposes, light cleaning work etc. a more painting effect is desired which So softer (finer) bristles required. The same applies for brushes, especially in the area of paintbrushes a broad gradation is desired. This will not only through the properties of each bristle, but also by the way the bristles are put together Bundling realized. The same applies to brushes in the hygiene area, e.g. Tooth, cosmetic, body and massage brushes. There are essentially three in toothbrushes Hardness levels - coarse, medium and fine - proven to be necessary, to meet the individual requirements of the user correspond.
  • the bristle carrier is hollow and the bristle bundles lie obliquely in this cavity and are at one Slider attached. The bundles reach through with one Wall of the bristle holder and holes can be adjusted to different lengths using the slider be pushed out or drawn in.
  • the invention has for its object in bristle goods any type with adjustable bristle hardness Users the possibility of customizing the Bristle hardness to allow for its needs without that it becomes hygienic due to contamination etc. Problems come, with the goal of a small size becomes.
  • This task is for bristle goods, the bristles of which have adjustable hardness, according to the invention solved that the bristles on the bristle carrier mounted elastically and when the force is applied, at least across its axis are deflectable, the deflection angle of the bristles is adjustable.
  • the hardness of the individual bristle or of several Bristles formed bundle not only by their geometric dimensions (length and cross section) and the Material from which they are made determines, but additionally influenced by the elastic mounting that it the bristle or the bundle enables force to dodge the bristles across the axis and get yourself to erect again after the strength has ceased.
  • the bending or re-erection ability of the bristle results from a combinatorial effect of the physical Properties of the bristle on the one hand and the elastic Behavior of the bristle bearing on the other hand. So that leaves the hardness of the bristle varies within wide limits.
  • the hardness is not by changing the bristle length and with it necessarily connected guidance of the bristles is reached, but only through measures in the area of the bristle foot. It there are no moving guide parts in the area of the free Length of the bristles with all their disadvantages, such as dirt, Incrustation, lack of cleaning ability, additional hard parts in the area of the bristles etc. Furthermore, with such bristle goods on the bristle carrier no precautions are taken to ensure that the adjustable Length recorded within the bristle holder rather, the bristles can be inside the bristle carrier be relatively short.
  • the elastic mounting can be designed so that deflection only in one direction transverse to the bristle axis is possible.
  • the bristles soften a back and forth movement only in one direction of movement act in this direction as soft Bristles as they line up in the other direction and act as hard bristles.
  • you can different effects in the two directions of movement e.g. in one more scratching and brushing, in the other more reaching and sweeping.
  • deflectability in all directions results in a kind of unstable storage with a corresponding degree of hardness in all directions.
  • the elastic storage can also be so be formed in the axial direction of the bristles results in a damping effect.
  • the bristles sit in an elastic bearing in a bristle holder and can be deflected while deforming the bearing. It is further preferably one on the bristle carrier elastic bearing acting actuator arranged, with the the amount of deformation of the elastic bearing and thus the deflection of the bristles is adjustable.
  • the actuating device therefore advantageously has means for Limitation of the deformation of the elastic bearing. In is a position influenced by the actuator the bristle deflection is greatest. The actuator can then be adjusted so that in the other extreme position the elasticity of the bearing practical is completely canceled.
  • a preferred embodiment of the actuating device has at least one rigid associated with the elastic bearing Bearing on that at a distance from the elastic bearing arranged and by means of the actuator to this is deliverable.
  • the rigid bearing thus acts as a kind adjustable abutment for the elastic bearing of the Bristles.
  • the travel distance is relatively short since it only bridging a distance between the complete Release of the elastic bearing via an increasing Limitation of the elasticity up to its approximation complete elimination.
  • the bristles with their elastic bearing in holes in a rigid perforated plate, the front of which forms the user-side surface of the bristle carrier, are fixed and the perforated plate on the back protrude, and that the actuator with the rigid Bearing in the areas of the perforated plate projecting elastic bearing attacks.
  • the perforated plate stationary part of the bristle holder and are the holes through the elastic bearings and the receiving them Bristles closed so that no gaps for storage and fixing dirt, care products etc. available.
  • the bristle goods have the same outer Appearance like bristle goods without adjustable Bristle hardness.
  • a first embodiment is characterized by that the actuator is a substantially parallel for the perforated plate in the bristle holder has, on its side facing the perforated plate has the rigid bearing associated with the elastic bearing.
  • the shelf is guided in the bristle holder and out a position in which the distance between the rigid and the elastic bearing is largest, with reduction this distance can be delivered to the perforated plate, whereby the deformability of the elastic bearings by the rigid stock is increasingly restricted.
  • the elastic bearings are increasingly moving released and can affect the force Deform bristles accordingly.
  • the shelf can also be used as a slider be formed, but preferably at least two in opposite directions parallel to the perforated plate on the bristle holder guided slide provided, the two each with respect sections of the rigid opposite the bearing axis Bearing.
  • the rigid bearings are at least divided in two, preferably in the axis of Bristle or the bristle bundle and is a bearing part arranged on one of the two sliders.
  • the elastic bearings are preferably made of pins or Sleeves formed, the circumferential in the holes of the Perforated plate are held and in which the bristles with are anchored at their fastening-side end.
  • the rigid bearings are expediently on the actuating device formed as bearing shells, which are in the direction expand to the elastic bearings and with them terminal outer contour correspond. Out of position greatest bristle hardness in which the rigid bearings terminal outer contour of the elastic bearing completely embrace and their elasticity almost completely pick up, give the bearing shells when moving away with the adjusting device the elastic bearings an increasingly greater scope for deformation.
  • the elastic Bearing-forming pins or sleeves on their Actuator facing the front a recess have into which a nose forming the rigid bearing Actuating device engages.
  • Nose and recess have congruent contours, and although preferably flared or conical rejuvenating.
  • the rigid bearings from a flat, parallel to the perforated plate Abutment is formed in the form of a plate and with terminal, flat end face of the pins or sleeves cooperates.
  • the bristles into one at their attachment-side end Are thickened with which they are melted in the elastic Bearings are anchored.
  • Another preferred embodiment draws is characterized in that the perforated plate with the on it fixed elastic bearings and the bristles interchangeable is attached to the bristle holder.
  • Bristle goods with replaceable bristle heads are known.
  • This goal is excellent with the solution of the invention agree that the Perforated plate with the elastic bearings and those of them captured bristles locked to the bristle carrier and can be ejected by means of the adjusting device.
  • the actuator fulfills two functions here, namely on the one hand, it serves to adjust the bristle hardness, on the other hand, the replacement of the bristle trim.
  • the bristle carrier has to accommodate the actuating device a recess in the area of the bristle trim on, in which the actuator is guided and that of the perforated plate is closed.
  • the actuating device can be actuated in different ways Realize wise.
  • the adjusting device with a Set plate cooperating screw on Bristle holder stored and with one on the back of the bristle holder accessible knob is provided.
  • the thread is Screw the shelf more or less to the elastic Bearing delivered, the travel, as already executed, must be very low.
  • the setting plate can be and thus adjust the bristle hardness while through Press the rotary knob to remove the perforated plate from the catch is solved and ejected.
  • actuating device has opposing slides, these are preferably by means of the bristle carrier accessible tongues can be actuated. Instead, come for actuation also rotary knobs with eccentrics or others Actuating means that such an opposite movement enable in question.
  • the elastic bearings Pins or sleeves made of an elastomer with rubber elastic Characteristics. You can be together with the Perforated plate in the multi-component injection molding process under simultaneous embedding of the thickenings on the fastening side of the bristles.
  • the bristle goods designed according to the invention exist So from just a few parts, namely the actual one Bristle holder, the perforated plate with the anchored in it Bristles of the actuating device and its actuating means.
  • the invention ideally indicates the possibility of a single brush bristles or bundles of different bristles Realize hardship by, for example individual bundles or bristles in the material of the perforated plate are fully injected while another Part of the bristle trim in the designed according to the invention elastic bearings. While the former bristles or bundles of bristles only by their free Length and its cross section determined bending behavior show, the latter bristles have an additional elasticity on. Furthermore, the deflection of the elastic stored bristles by appropriate geometric Design the elastic bearings differently.
