Definitions

  • the invention relates to a helmet, in particular a bicycle helmet.
  • a helmet can be used for example by a cyclist to protect his head.
  • Such safety helmets have a shock-absorbing body, which consists of correspondingly shock-absorbing plastic material.
  • the basic body is disguised from designerischen reasons regularly with a visually attractive decorative shell from the outside.
  • the helmet can be fastened to the person's head by means of fastening straps guided under the chin of a person.
  • this also has an adjustment for a guided through the helmet headband, which is located in the helmet opening and which rests on the head.
  • the two ends of this headband are attached.
  • the length of the headband can be reduced or enlarged and thereby secure the helmet safely and quickly on the head and remove it.
  • the two can Attachment members to which the respective end of the headband is attached to the adjusting device, are pulled away in each case to opposite sides of the knob.
  • the fasteners can not be moved away, since the connection between the fasteners and the knob over each a drawstring that can not transmit compressive forces occurs.
  • the present invention seeks to provide an adjustment of the type mentioned above, which allows only with mechanical aids shortening or lengthening of the headband alone by pressing a knob present on the adjusting, without a corresponding Headband adjustment by pulling or pushing on the headband on the adjustment holding fasteners is required or possible.
  • the adjustment device is equipped with two independently acting pawl teeth.
  • the adjusting device that is, for example, when turning the rotary knob present in the adjusting device in a certain direction of rotation, only one pawl toothing is always unlocked.
  • the other pawl toothing is not unlocked and thereby prevents an adjustment of the slide parts in the direction of adjustment (direction of rotation) other direction.
  • Relative displacement of the slide parts toward or away from one another which results in a corresponding shortening or lengthening of the headband, is thus possible exclusively by actuating the actuating device, for example by appropriately turning a rotary knob. Pulling or pushing on the slide parts can not lead to a mutual displacement of the two slide parts by the always effective pawl teeth.
  • the two slide parts can have in their two end regions a rack formation, which are simultaneously engaged with a gear.
  • the two ratchet teeth can be arranged stationarily on the adjusting device and, for example, can be present one above the other circumferentially inside a stationary sleeve.
  • the two ratchet teeth are each blocking effect in opposite directions.
  • the corresponding with the pawl teeth to be brought into engagement two pawls may be formed in a kind of disc such that they by pressing the adjusting device such as in particular a rotary member, which may be, for example, the lid of said sleeve, individually, never together, operated and unlocked can be.
  • the rotary member such as a rotary knob, can engage with protruding pins in said cantilevers so that when turning the rotary member in a certain direction, only one of the two pawls is always unlocked and the other pawl remains in its locking engagement with the pawl teeth.
  • the two pawls can be present on elastically deformable ver cantilevered example of the disc.
  • the adjusting device may include a transversely elongated trough-like part into which the two end portions of the two slide parts protrude from the outside in the transverse direction. Further details of such an adjusting device can be found in the claims further listed in the claims and the following embodiment.
  • each luminous body can be provided centrally or laterally outside. These can have light-emitting diodes as light sources. The actuation of a light source can be done by pressing the respective luminous body in a simple and secure manner.
  • FIG. 1 is an external perspective view of a to be attached to a bicycle helmet adjusting device according to the invention
  • FIG. 2 is a plan view of the adjusting device according to FIG. 1, in a partially disassembled state, FIG.
  • Fig. 3 is an enlarged partial view of the adjustment of their slide parts causing structural components. WAYS FOR CARRYING OUT THE INVENTION
  • An adjusting device 10 is attached to the two ends 12, 14 of the webbing 16.
  • the webbing 16 is attached to a helmet, not shown in the drawing. When wearing the helmet, the webbing 16 runs around the head almost completely. The adjusting device 10 is then located in the rear head area.
  • the adjusting device 10 has a trough-like part 18 which can be closed on its rear side by two flat material webs 20, 22.
  • the two flat material webs 20, 22 are integrally connected via a kind of film hinge with the trough-like part 18 made of plastic. Dashed is a partially open position of the two flat material webs 20, 22 indicated.
  • the two flat material webs 20, 22 can be swung apart by approximately 180 ° from their closed position shown in FIG. 1.
  • the two flat material webs each have an eyelet formation 24, 26.
  • a knob 28 which has an axially projecting shaft 30 which projects into the trough-like part 18.
  • the axial screw hole 32 is in the closed state of the trough part 18, in which the two flat webs 20, 22 are folded with their two eyelets 24, 26, a not shown in the drawing screw from behind through the two eyelets 26, 24 and passed screwed into the axial screw hole 32.
  • the knob 28 can thereby be rotated freely in both directions of rotation 34, 36.
  • the trough-like part 18 has laterally a left and right slide part 40, 42. At the protruding from the trough-like part 18 two ends of these two slide parts 40, 42, the respective ends 12, 14 of the headband 16 are attached.
  • Each of the two slide parts 40, 42 has in its respective end region 50, 52 in the longitudinal direction of the slide parts, that is in the transverse direction or adjustment 44, an elongated opening 46, 48.
  • a rack formation 58 or 60 available at the outer opening edge 54 of the end portion 50 and 56 of the End region 52 is in each case a rack formation 58 or 60 available.
  • the gear 62 is centrally on a kind of disk 64 available.
  • the disk 64 is C-shaped in plan view. It has two cantilevers 66, 68, which are at different levels to the disc plane.
  • each recess 70, 72 has at its the axis of rotation 74 facing and at the end of the cantilever Kragarms 66, 68 lying end an inner edge surface 76 and 78 with a slightly different from the circular arc, towards the collar end slightly spiral opening contour.
  • the disk 64 lies in a cup-shaped sleeve 84 integrally formed on the trough-like part 18.
  • the knob 28 protrude from its inside two pins 90, 92 and into the recesses 70, 72 of the cantilevers 66, 68 into it.
  • the two pins 90, 92 are pivoted counterclockwise about the axis of rotation 74.
  • the pin 90 (Fig. 3) pushes the cantilever 68 in the counterclockwise direction about the axis of rotation 74.
  • the spiral contour of the edge surface 78 of the cantilever 68 of the cantilever 68 is thereby easy pivoted inward while his pawl 82 pulled out of the teeth 88.
  • the disk 64 and integrally formed thereon gear 62 can thus be rotated counterclockwise.
  • the other pawl 80 slides along unhindered along the pawl teeth 86 that are not blocking in this direction. In the opposite direction of rotation, the pawl 80 moves from the pawl teeth 86 and the other pawl 82 is in the other pawl teeth 88 locking.
  • two light modules 94, 96 are mounted on the outside of the adjusting device 10 in the present example case.
  • the two light modules 94, 96 are self-sufficient in themselves. So they contain the corresponding electrical circuit and a small battery.
  • the light emitting diode 98 present in each case in the light module is switched on and off by pressing on the relevant light module.

Abstract

La présente invention concerne un dispositif de réglage (10) destiné à modifier la longueur d'une sangle de tête (16) d'un casque, en particulier d'un casque de cyclisme, le dispositif de réglage présentant deux parties de réglage (40, 42) qui peuvent se déplacer l'une par rapport à l'autre dans une direction de réglage (44). Un mécanisme de verrouillage empêche et bloque le mouvement mutuel entre les deux parties de réglage (40, 42) dans une direction de réglage (44). Deux mécanismes de verrouillage (80, 82, 86, 88) de ce type sont utilisés de sorte que dans les deux directions de réglage (44), un mécanisme de verrouillage reste toujours débloqué lorsque l'autre est bloqué.
