Definitions

  • the invention relates to an adjustment for the effective length a band, preferably for the band encompassing the head a safety helmet with a striker with a disc-shaped rotatable adjusting means as well as a helmet such an adjustment.
  • the striker is flat trained so that the gap between the head and the Helmet shell can be chosen small.
  • the thickness of the Striker smaller than its width.
  • Protective helmets are known that have a inside adjustable band that holds the wearer's head inside the Helmes spanned.
  • This headband is adjustable, so one Size of a hard hat that normally matches the head surrounds to allow air to circulate different head sizes can be adapted.
  • This Headband is often in the area of one of its ends The back of the head is punched while the other end of the tape is from the Band plane has approximately orthogonally protruding knobs, which in Holes of the other end of the band are pressed in this way. that the effective length of the band can be adjusted to the head circumference.
  • Headbands with a striker are also known and through the band ends protruding into the striker Sliding a disc against each other. This Strikers work with a ratchet mechanism, which in the The area of the back of the head between the head and the helmet is difficult to close is operate.
  • the invention is therefore based on the object Adjustment for the headband of a helmet or one To offer a helmet with such an adjustment for the headband, which is easy to use with the helmet on and the reliably maintains the found setting.
  • Actuator is stored in the striker and with one part its circumference protrudes from the housing and by a Band guide in the area of the housing of the striker and through a toothed band, the tooth or teeth being approximately orthogonal protrude to the band level, as well as a spiral or parts of which on the adjusting means such that the tooth or teeth of the band inserted into the band guide into the spiral intervention.
  • a plurality of spirals or similar curve sections on the band ends be formed and the teeth are in on the adjusting means suitable radial and angular position provided.
  • the spiral is designed to be self-locking. The spiral only has a turn that is about 36 °.
  • the term spiral must do not comply with the strict mathematical law, rather it is important that a pivoting movement of the adjusting means to a directionally predetermined positioning movement of the or of the band ends.
  • Self-locking involves a strong one Reduction of the actuating movement on the change of Tape length. This results in a small force for actuation of the adjusting means.
  • the disc-shaped adjusting means can therefore be operated with the thumb on the mounted helmet.
  • a small toothing on the circumference of the disc-shaped Actuator allowed even with sweaty or greasy Fingers reliably adjust the headband of a helmet. Because of the resulting height, it is also recommended inside of the striker to be moved against each other Band ends band-shaped and in the interest of high flexibility train flat.
  • the striker is completely made of plastic manufactured and comes without screws and others Fasteners.
  • the disc-shaped adjusting device is on guided its extent in the striker.
  • the front of the Adjustment means is covered by the band end to be adjusted.
  • the solution according to the invention allows rapid adjustment of the Length of the headband, e.g. if a helmet is to be awarded.
  • the headband in the helmet is adjusted with a "Thumb slide" over the adjusting device. You don't have to Try out the settings. Put on the helmet with your thumb on Turn the adjusting means and the helmet fits.
  • the disc-shaped adjusting means on both ends Spiral or parts thereof and both ends of the tape in the Striker inserted from opposite sides are and a tape guide for the tape ends on both sides of the Actuating means is provided in the housing. This measure increases the maximum adjustment range of the headband.
  • the ones to be adjusted Belt ends immediately enclose the adjusting means.
  • the band channel or channels are formed like sacks are. Both ends of the band are adjusted.
  • the so achieved Adjustment range is enough to one for most cases to achieve adequate adaptation to the head circumference. Therefore the tape ends don't have to be on the opposite side be brought out.
  • the spiral on the adjusting means has only about one turn, which is arranged on the periphery of the disk-shaped adjusting means. It is arranged on one level. In connection with the preferably symmetrical adjustment of both strap ends, this results in an overall adjustment of the head strap length which corresponds approximately to 1.5 times the diameter of the disk-shaped adjusting means. For normal cases, this offers an ample possibility of adjusting the belt length.
  • the Teeth on the belt ends one in top view on the Contact point with the spiral opposite a round shape have flattened contact surface that corresponds to the slope the spiral is slightly inclined.
  • the flattening can be a Circular section with a radius that is much larger than the maximum radius of a full circle, which is in the pitch of the Spiral fits into it.
  • the tooth in the top view can be a oval, a lens shape or the shape of a segment of a circle to have. This measure allows it with little Surface pressure values to work.
  • the striker with the toothed band ends is formed as a separate unit and connected to the headband by coupling pieces becomes.
  • the strap ends inserted into the striker on one Section outside the striker are cranked and the or the teeth on the recessed side of the band ends are trained. So both ends of the band can be the same be trained and offset by 18 ⁇ ° Mount the actuating means overlapping each other between them lock in.
  • Band length should be constructed so that the striker is in sandwich construction is manufactured with two half-shells in which one or each band guide is formed and the disc-shaped adjusting means in between.
  • the forces emanating from the band ends essentially close within the disc-shaped Actuator.
  • the housing only needs a small overturning moment Take over the actuating means. That allows an easy and small dimensioned housing for the striker.
  • Another way to preset the effective Headband length for a safety helmet is after one Educational feature of the invention seen in that the free ends of the band pieces, each with one end in the Protrude striker, two each in the sense of a change the effective tape length from each other Connection points for the headband are otherwise provided.
  • the adjustment options are so extensive that everyone sufficiently large helmet adjustable to all common head sizes is. It is then only a matter of appearance whether a large one Helmet for a small head is accepted or not.
  • FIG. 1 shows a cut open bicycle helmet 1 with a headband 2, a chin strap 7 and cushions 1 11, 11, 12.
  • the headband hangs on shoulder straps 8, 9 in helmet 1 and is worn by a striker 3 closed.
  • the effective length of the Helmet band 2 is on an adjusting means 4 in the striker 3 set.
  • the locking piece 3 protrudes on each side Band piece 6, 13 out, each with a coupling 5, 14 with the Headband 2 is connected in the rest.
  • the striker 3 is part of a locking unit (Fig. 2), which in addition to the striker 3 comprises two pieces of tape 6, 13, the with the couplings 5, 14 at the ends of the headband 2 in the rest are connected.
  • the band pieces 6, 13 point in the Near their longitudinal center each have an offset 2 ⁇ , 28, which the Headband 2 centered on striker 3.
  • the ends of the band pieces 6 pointing away from the closing piece 3, 13 each have two mounting holes, namely one Mounting hole 17 and another under the coupling 14, in which a coupling pin 16 engages.
  • the clutch 14 connects the end of the headband 2 in the assembled state the mounting hole 15 with the band piece 13. Corresponding applies to the coupling 5 with the coupling pin 23 and that Mounting hole 22 on the other side of the striker 3.
  • the striker 3 itself has two housing halves 21, 36 which 4 and 12 are shown in detail. In the In use position, toothed circular sections protrude above and below of the actuating means 4 from the housing 21 of the striker 3 out. The disc-shaped actuating means 4 can thus with a thumb or thumb nail are pressed with the helmet on and changes the effective length of the headgear 2.
  • the Training of the striker 3 with the two band pieces 6, 13 allows practically all helmets a simple and in Headband unchanged in shape for all head sizes to be provided and the entire adjustment to the individual Shift head size to the clamping unit.
  • the clamping unit shown in Fig.2 to use different materials for the band pieces 6, 13 on the one hand and the headgear 2 on the other.
  • a rough one Presetting is carried out by arranging the clutch 14 in the shown position or by moving over the Mounting hole 17. The same applies to the opposite side with the coupling 5. This creates a symmetrical arrangement of the striker on the back of the head Helmet wearer on the part of the couplings 5, 14 ensured. in the remaining are by turning the disc-shaped Setting means 4, the band pieces 6, 13 synchronously in the striker 3 in or out of this, what the centric Arrangement of the striker on the back of the helmet wearer's head ultimately ensures.
  • the striker 3, as shown in Fig.3 to Fig.12 only 3 parts, namely from the two housing halves 21, 36 and the disk-shaped adjusting means 4. Overall, there is a Sandwich-like structure of the striker to adjust the effective length of the headband 2.
  • the housing half 21 has a bag-like tape guide 41 for the tape piece 6. The end of the band piece 6 inserted into the striker traverses the entire housing 21, 36, but does not emerge, because the tape guide 41 is bag-shaped.
  • pins 39, 4 ⁇ are provided, which in corresponding bores 37, 38 on the other housing halves 36 Immerse (Fig. 12).
  • End of the band piece 6 carries a plurality of teeth 24, 25, 26, 27 that cooperate with a plane spiral 29 on the actuating means 4.
  • the spiral 29 is designed to be self-locking. Teeth 24, 25, 26, 27 are evenly spaced and on the recessed hinge side arranged.
  • the teeth have in the in Figure 6 an oval shape and and are for better adaptation to the inclination of the spiral 29, as in 43 shown, slightly slanted.
  • On the bend 28 opposite side of the band piece 6 are the two Mounting holes 22, 43 for the headband 2 in the rest trained, on which the clutch 5 is optionally placed.
  • the actuating means 4 is characterized by a plane spiral 29, 31 on both ends. It is easy on his toothed circumference 3 ⁇ in the housing 21, 36 out.
  • the spiral 29 has essentially only one turn and one Gear. Because of the sufficient adjustment and the better optics was leading to a leading out Strap end on the opposite side of the striker 3 waived. The same happens with the spiral 31 the underside of the actuating means 4 and the band piece 13 with his teeth 18, 19, 33, 34. After the end 35 on the headband 2 fixed on the helmet side is under the Band piece 13 with its orthogonal from the band plane 32nd protruding teeth 18, 19, 33, 34 almost the complete Diameter of the spiral plane 31 and is in one Band guide 42, which is bag-shaped, in the housing 36 guided. This is about 1.5 times the total Diameter of the adjusting means as an adjustment path for the Band pieces 6, 13 and thus for the effective band length of Headband 2 available.
