Definitions

  • the invention relates to a hair brush according to the preamble of claim 1.
  • Hair combs that more or less conform to the shape of the head are known. These hair combs are equipped with soft bristles, which adapt to the shape of the head, that they bend more or less strongly. However, the softer the bristles are, the worse is their combing effect as a rule. In addition, in brushes whose adaptability is ensured only by their soft bristles, the bristle trim can not adapt well enough to the head shape, since calculated just in the middle of the bristle trim bristles that would actually give the farthest to adapt to the head shape to reach, least yield, since they are supported by the surrounding bristles and therefore prevented from yielding.
  • Hair brushes which better conform to the shape of the head are therefore heretofore provided with a trim of bristles which are anchored to a flexible, compliant bristle support pad and in this manner form a bristle trim that is better able to conform to the shape of the head
  • the bristles of such brushes are made of metal pins or resilient metal wires which are held at one end by a rubber membrane or plate which forms the bristle carrier pad.
  • the bristles are pressed against the scalp during brushing.
  • the resulting forces deform the bristle carrier cushion, or the rubber membrane.
  • the base of the bristles shifts, causing the position and / or the spatial Alignment of the bristles changes, thus adapting to the shape of the head.
  • a hairbrush having a trim of bristles, which is attached to a flexible bristle carrier pad.
  • the bristle carrier pad is under the forces occurring during combing according to the fact that in this way the base of the respective bristles and thus the bristle displaced as a whole and / or so that the bristle pivots as a whole, d. H. shift their orientation in space.
  • the bristles are made of plastic, the bristle carrier pad is designed as a flexible membrane and the bristles and the membrane are made of a single piece, which is made by injection molding.
  • the bristles can therefore not be separated from the membrane without destruction, between the bristles and the membrane exist in the root area of the bristles, even under the microscope considered no joints.
  • the bristles and the membrane from which they depart not only consist of one piece, but they are also formed einstofflich, so consist of a single plastic material.
  • the plastic membrane and bristles are injection molded in a single shot. This allows an extremely rational and cost-effective production
  • a preferred material for making the bristles and membrane is HDPE.
  • the bristles and the membrane are not made of a rubber-elastic material, or plastic
  • membrane can be best described functionally.
  • a membrane according to the invention a very thin plastic plate is called. In the simplest case, this can be bent more than insignificantly around at least one axis by the forces which occur during the intended use of the brush.
  • the thin plastic plate is designed so that it can be bent more than insignificantly about two perpendicular axes of the forces occurring during normal use of the brush forces.
  • the membrane can thereby be readily deformed so that it forms on one side of a substantially spherical surface - preferably that side forms a spherical surface from which the bristles protrude
  • the membrane has two main surfaces, the bristles protruding from at least one of these main surfaces.
  • the main surfaces are characterized by the fact that for each of the main surfaces their free surface area is greater by at least a factor of 7.5, better by at least a factor of 25, as the sum of the free surface of all secondary surfaces (ancillary surfaces are here the surfaces that form the narrow sides of the membrane).
  • the thickness of the membrane perpendicular to the surface of its major surfaces is preferably in the range between 0.25 mm and 1.25 mm and ideally in the range between 0.3 mm and 0.8 mm, in each case the limit values included.
  • the membrane is a very thin-walled structure, d. H. in the broadest sense a cuboid, which has two very large edge lengths and compared to a very small height.
  • the membrane with at least one and preferably several slots.
  • the slots are substantially parallel to each other and preferably at least substantially parallel to the longest side edge of the membrane.
  • the diaphragm may have a certain thickness precisely because of the slots, so that it does not prematurely yield due to its thickness and the pretension mediated to it by the pressing on its auxiliary surfaces when the brush is pulled through the hair, but only when it is done with a certain emphasis.
  • the edges of the membrane which did not touch a slot, do not touch even when the membrane is relaxed.
  • the slots are thus “recesses” in the membrane. In this way prevents the edges of the slots are supported against each other, or get caught in the deflection of the membrane, thus hindering their flexibility.
  • edges of the at least one slot are corrugated in the direction perpendicular to the main surface of the membrane.
  • slots can be made whose edges are very far apart without overly reducing the area of the main surface on which bristles can be placed.
  • the membrane has a circumferential, all around self-contained edge.
  • the membrane can be particularly easily and safely clamped in the bristle carrier and, above all, the membrane can be particularly well biased by the bristle carrier (so that it assumes a spherical shape) when it has a self-contained edge all around.
  • the membrane is macroscopically curled in itself.
  • the term “macroscopic” means that "waves" of the membrane in the form of the surface roughness which is not visible to the naked eye, or almost invisible, do not constitute a corrugation in the sense of the invention. Rather, according to the invention, only those waves which favor compression or elongation of the membrane and thereby promote the deformation of the membrane to, for example, a convex structure - are actually compressed by the regions of the membrane which tend to be compressed in such a deformation can not or less hinder the desired deformation
  • the corrugation is uniform. It is particularly good if the corrugation is formed so that the distance between a wave crest and an adjacent trough in the direction perpendicular to the wavefront between 7.5 mm and 0.5 mm, and ideally between 1 mm and 3 mm.
  • the membrane and the bristles connected to it are preferably designed so that the membrane is in a completely relaxed state (which it preferably occupies only before its incorporation into the bristle carrier) is substantially flat - apart from the corrugation that is possibly her own ,
  • the bristles are molded onto the membrane so that they substantially converge in this state, i. H. the bristles are inclined towards each other so that their tips are closer together than their roots, with which they pass into the membrane.
  • Such a design has the advantage that the bristle field, or its bristles and only then show the desired spatial orientation when the membrane has been installed under the structurally predetermined bias in the bristle carrier and has thereby arched.
  • the hair brush comprises a bristle carrier which preferably merges into a brush handle and the bristle carrier has a membrane receiving window which is designed so that the membrane can be fixed in the membrane receiving window such that the membrane faces towards the side from which its bristles exit , has a convex and preferably multi-convex, or convex curvature;
  • FIGS. 14 to 19 Similar to the FIGS. 1 to 6 , and 8 to 13 show the FIGS. 14 to 19 , and 20 to 25 and FIGS. 26 to 31 each show a third, fourth and fifth embodiment, respectively, in each of FIGS FIGS. 1 to 6 well-known positions.
  • the hairbrush according to the invention comprises a brush handle 2 and a bristle carrier 3.
  • the bristle carrier 3 is stirred here as a peripheral frame, which has a membrane receiving window 4.
  • FIG. 7 shows a unit of the bristles 5 and the integrally connected membrane 7
  • the bristles 15 are preferably slightly conical and thereby ultimately adapted to their load - where the load is highest, namely in the region of the bristle foot, the bristle is the thickest.
  • this embodiment promotes their mold release.
  • the bristles are in this embodiment in one piece and einstofflich connected to the membrane 7. Pretty good on the basis of FIG. 7 the corrugation of the membrane 7 can be seen. This curl is also based on the FIG. 1 to recognize, one recognizes there that the waves form a wavefront, which runs substantially perpendicular to the longitudinal axis L of the hairbrush.
  • the attachment of the membrane 7 in the membrane receiving window 4 is advantageously carried out either by welding, or in that the bristle stocking is clamped by a frame 14 which is pressed from one side into the bristle receiving window and the membrane 7 against a paragraph not shown here Press bristle pickup window and thereby holds between himself and this paragraph in the press fit
  • the circumference of the membrane along its minor surfaces 13 is slightly larger than the inner circumference of the membrane receiving window 4.
  • the soffits of the membrane receiving window 4 press on all sides on the minor surfaces 13 of the membrane.
  • the membrane is compressed in itself, it dodges and forms a curvature, similar to the curvature that was found in the former bristle carrier cushion in the form of rubber plates.
  • this can also be such that the membrane receiving window 4 and the circumference of the membrane 7 are matched to one another along their secondary surfaces 13 such that the membrane 7 can be inserted into the membrane receiving window 4 substantially free of stress. In this case, the membrane remains substantially even after their insertion.
  • the membrane is provided with slots 10, the edges 11 and 12 are each spaced so far apart that these two edges do not meet even in the relaxed state of the membrane 7.
  • the membrane forms a plurality of bending beams, which are filled with bristles so that the bristle base points can escape under load, so that the respective bristles can preferably move as a whole.
  • the slots preferably do not run in a straight line, but here form a wave pattern.
  • the bending beams are stabilized in the transverse direction perpendicular to the longitudinal axis of the hairbrush, i. they make a torsion better resistance.
  • the membrane 7 is preferably provided with a corrugation, such as FIG. 7 implies and how they are based on the FIG. 1 can be seen.
  • the corrugation of the membrane makes its bending beams more flexible in the direction of the longitudinal axis.
  • the Bending beams can then bend better - a firmly clamped at its two ends bending beam is known to be hindered in its curvature, since tensile forces occur in the direction of its longitudinal axis by the clamping of its two ends in bending, which hinder the further bending. This effect eliminates the curl, as it allows stretching or compression.
  • the corrugation is advantageous both when the membrane is just installed, as well as when the membrane is biased by their incorporation into the membrane receiving window 4 so that it is crowned. Because in this latter case, it facilitates the corrugation that the membrane, or their bending beam take the desired spherical shape.
  • the corrugation is, however, also advantageous, as already mentioned, if the membrane is substantially planar, ie. H. without bias, is clamped in the membrane receiving window 4. The corrugation then allows the bending beams to better deflect, as it allows a certain elongation of the bending beams.
  • the membrane and the bristles are arranged relative to each other and designed so that the bristles are aligned after insertion of the membrane 7 in the membrane receiving window and thus possibly associated deformation of the membrane 7 substantially parallel to each other.
  • the bristle carrier in addition to the membrane receiving window, preferably in the region of the brush handle remote from the tip of the brush, in turn, is equipped with an additional bristle field Z.
  • These bristles are mounted on the rigid bristle carrier and therefore able to oppose a possible deformation, or forces that tend to deform, higher resistance.
  • This bristle field for example, very be used well to pull the brush when combing long hair with some force through that part of the hair, where tangles or adhesions are to be eliminated.
  • FIGS. 8-13 show a second embodiment of this second embodiment corresponds to the first embodiment as far as possible. Because of this, what is said for the first embodiment also applies to this second embodiment. The only difference with the first embodiment is that in the second embodiment, a narrower bristle stocking is provided and the slots 10, which are incorporated in the membrane 7, are more corrugated.
  • FIGS. 14-19 which in turn only show a different curl of the slots in the membrane.
