Definitions

  • the invention relates to a hair curler, consisting of a plurality of circumferentially closed, circular cylindrical tubes with stepped diameters, which are arranged coaxially one inside the other and are telescopic with a sliding fit, form a rigid tube in the pulled-out state of the hair curler and each have a large number of openings and intervening crosspieces and crosspieces Have pull-out limiting means.
  • a hair curler of this type is known from US-A-3,835,871.
  • pull-out limiting means in the form of inner and outer flanges which form stops with one another.
  • One of the end flanges also has a flange at the free end, which holds the tubes together when pushed in.
  • this flange stands in the way of easy assembly.
  • the curler is impractical to use because the individual tubes can be rotated relatively, which interferes with the winding of the curls.
  • US-A-3,593,724 shows a telescopic hair curler consisting of an outer tube and an inner tube.
  • the inner tube has a continuous longitudinal slot into which a plurality of axially aligned inner projections of the outer tube engage. Angled slots branch into the slot of the inner tube, into which the projections of the outer tube can enter. A locking of the two tubes is thus achieved, which acts both in the axial direction and in the circumferential direction, but there is no real extension limitation if the projections lie in the slot of the inner tube when telescoping the tubes.
  • the slotted sleeve is unstable and prevents the tubular casing from being formed as a latticework with large openings.
  • US-A-2,229,841 shows a hair curler with polygonally contoured individual tubes which can be rotated relative to one another and, depending on the rotational position, do not guarantee a wobble-free connection. There is also no effective pull-out limit.
  • the object of the invention is to design the hair curler of the type mentioned at the outset in such a way that the tubes have a large number of air passage openings, but nevertheless, with a sufficiently small wall thickness in the extended state, produce a hair curler of high stability which is easy to manufacture and assemble and which is high Usage value in that there is an effective pull-out limit and a relative rotation of the tubes to each other is excluded.
  • the longitudinal webs stabilize the tubes and allow the tubular jackets to be formed over their largest axial area in the form of a lattice work with narrow, intersecting webs and large openings that remain between them. This training is important for a quick drying of the coiled hair.
  • the longitudinal guides can be designed as continuous slots, so that a peg-shaped guide element engages in the slot in the adjacent tube, thereby simultaneously causing a pull-out limitation and protection against rotation. If according to an embodiment of the invention the longitudinal guide as Groove is formed, which thus has a groove bottom, so can be provided at the ends - but also in intermediate positions - recesses in the groove bottom, in which the preferably spring-loaded pin of the other tube engages. An undesirable longitudinal displacement of the tubes to each other during use is therefore excluded.
  • the longitudinal webs preferably run axially parallel according to an alternative, the longitudinal webs run helically.
  • a hair curler 10 consists of four telescopic circular cylindrical tubes, namely an end tube 12 of the largest diameter, an end tube 14 of the smallest diameter and two inner tubes 16, 18 arranged between them. All tubes 12-18 have the same length, which is 65 mm in the exemplary embodiment. The outer diameter of the largest tube 12 is approximately 23 mm and that of the smallest tube 14 is approximately 16 mm. The diameter gradation from tube to tube is approximately 2.2 mm and the overlap of two tubes in the extended state of the winder 10 is 13 mm. All tubes 12-18 are open at their ends and the respective jacket consists of intersecting webs 20, which form a large lattice work with a large number of large openings 22.
  • all other tubes 14-18 have two diametrically opposed longitudinal guides 24 , in the form of axial slots that come close to the tube ends.
  • all other tubes 12-16, 18 have two diametrically opposed guide pins 26 which extend radially inward from the tube jacket by approximately the wall thickness of the tubes and engage in the longitudinal guides 24 of the respective subsequent tube.
  • the two guide pins 26 of each of the two inner tubes 16, 18 lie in an axial plane which forms an angle of 90 ° with the second axial plane containing the two longitudinal guides 24. It is thereby achieved that the pair of longitudinal slots 24, 24 is circumferentially offset by 90 ° from tube to tube. The tubes could therefore be pushed fully into one another, with all of the guide pins 26 coming to lie in a radial plane.
  • the length of the guide guides 24 is determined such that each tube protrudes somewhat from its neighboring tube when the hair curler 10 is inserted. At these projecting ends, the tubes can be gripped and pulled out more easily.
  • Each of the tubes 12-18 has a conical bevel 28 as a transition section at the end leading the next smaller tube.
  • the guide device consisting of the longitudinal guides 24 and the guide pins 26 provides protection against relative rotation of the tubes and acts as a means of limiting the pull-out.
  • the tubes 14, 16, 18 in their respective shells have a pair of diametrically opposed longitudinal webs 30 which form part of the latticework.
  • the longitudinal guides 24 are arranged centrally in these longitudinal webs 30.
  • the outer sides of the webs 20, 30 forming the latticework are provided with a pile coating 32.
  • This pile protrudes radially from the tube jacket in the extended state of the telescopic roller 10 and serves to anchor the hair when handling the hair roller.
  • the pile folds and creates a frictional connection between the tubes, which ensures that a certain tensile force is necessary in order to extend one or more tubes.
  • the guide pin 26 can either be integrally formed as a one-piece projection during the injection molding of the tubes or can be designed as a separate pin which, e.g. is pressed into a locking hole of the respective tube and thereby locked.
  • FIG. 5 shows a variant in which the longitudinal guide 24 is designed as a groove into which the pin 26 fits.
  • This is formed in two parts and comprises an outer sleeve 34, which is inserted into a radial bore of the respective tube, and an inner sleeve 36 closed at the bottom with built-in spring 38.
  • the pair of longitudinal guides is missing in the largest tube 12 and the guide pin 26 in the smallest tube 14. It is understood that the guide principle can also be reversed.
  • the guide pins 26 are then assigned to the rear end regions of the tubes 14, 16 and 18 and do not project radially inwards but outwards.
  • the embodiment in which the pins 26 point radially outward makes it possible, in conjunction with two slot-shaped or groove-shaped longitudinal guides 24 lying diametrically opposite one another, to use a common radial pin, the ends of which form the pins 26.
  • This radial pin completely penetrates the respective tube. It can be easily formed in two parts with a built-in spring, which can be installed just as easily.
  • the four-section hair curler shown then has three such radial pins, of which the two outer ones are parallel and the middle one is arranged transversely thereto. When retracted, the three radial pins touch each other.
  • tabs are pun out elongated tabs on three sides at the ends of three of the four tubes or to separate them accordingly during injection molding, so that a bending zone is formed on the fourth side, with which the tabs are connected to the respective tube jacket stay. These tabs then act as spring tongues and carry the pin 26 at the free end opposite the bending area. When the pins run onto the groove bottom of the longitudinal guides 24, the ends of the tabs move slightly in the radial direction, without this impermitting the telescopic nature of the tubes with special needs.
  • the tabs can be oriented in the longitudinal direction of the tubes, but also just as well in the circumferential direction.
  • the 4-section hair curler shown can also consist of 2 or 3 tubes but also of more than 4 tubes.
  • the longitudinal guides 24 are arranged axially parallel, that is to say in a straight line.
  • the pitch of the helical line preferably being such that a relative rotation of at most 360 ° is sufficient for the full extension movement.
