Definitions

  • the invention relates to a variable length locking band for headgear according to the preamble of claim 1.
  • the present invention relates to all headgear, which are suitable to be provided with a length-adjustable locking band, such.
  • a length-adjustable locking band such as safety helmets, bicycle helmets, light Industrie modernstoffkappen and the like.
  • the toothed belt has an end face, i. on the narrow side arranged teeth on.
  • the lock slide which can be brought into engagement with the toothed belt, therefore also has lateral tooth combs or engagement pawls which are suitable for being brought into engagement with the obliquely arranged toothing of the toothed belt.
  • Disadvantage of such a known latching closure with a toothed belt and a locking slide is given the relatively high cost in the production of these two parts. Namely, it must be connected to the closure slide with its own webbing, as well as the rack, which is opposite to the shutter and is engageable with this.
  • Another disadvantage is that for closing the locking strap two hands are needed, because with one hand, the rack must be held, while with the two fingers of the other hand, the two opposing locking latches must be operated on the shutter.
  • the invention is therefore based on the object, a snap closure of the type mentioned in such a way that it is suitable for a single-handed operation on a helmet in the occipital region.
  • the invention is characterized by the technical teaching of claim 1.
  • an essential feature of the invention is that the latching device, which is attached to the one webbing, is pivotally spring loaded on one side and a tooth comb is disposed at the free resilient end, which is opposite to the toothing of the opposite toothed belt and selectively engageable or disengageable therewith is.
  • the essential advantage is achieved that the locking device can be brought only with a finger of one hand in an open position or in a closed position and spring-loaded always springs back into the closed position.
  • the closed position is characterized in that the toothed comb arranged on the free resilient part of the latching device can be brought into toothed engagement with the associated teeth of the toothed belt.
  • this actuator plate acts as a one-armed lever, and the entire latching device pivots about a horizontal pivot axis which is parallel to the plane of Toothed belt and the webbing is around this axis and thus brings the tooth comb out of engagement.
  • the actuating plate merges via vertical connecting walls into a base plate and that in the region of the base plate longitudinally extending slots are arranged, which form queritessschwownende recesses toward the side walls of the locking device.
  • the side walls are in this case via corresponding guide lugs always in guiding engagement with the toothed belt, while the slots delimit the side walls of the actuator, so that this actuator - consisting of the actuating plate, the connecting walls and the base plate - is resiliently formed to the side walls.
  • the entire arrangement is injection-molded from a material-integral plastic, because this saves manufacturing costs.
  • the entire locking device is formed in one piece of material from the same plastic material as the webbing attached thereto, so that the webbing and the locking device form a single plastic injection molded part.
  • the webbing gives a different flexibility than the flexibility of the material on the webbing attaching locking device.
  • the toothed band material integral with the there on it attaching webbing is formed.
  • it is a part made by plastic injection molding, so that the webbing and the toothed belt are made of a material-integral plastic.
  • it may be provided to form the toothing in the region of the toothed belt from another (eg harder) plastic, as the remaining material of the webbing on which the toothed belt attaches material ein Committeeig.
  • the tooth bevels of the teeth of the toothed belt are inclined at an angle to the vertical and the teeth of the toothed comb of the detent device have the same inclination.
  • the invention provides in a preferred embodiment, two actuation options for the locking device. It is essential that two different handles are arranged on the actuating plate of the locking device.
  • the one handle consists of a small guide lug, which is arranged in the region of the pivotable part of the latching device and is formed approximately (above) over the toothed ridge of the latching device. In attack and train on this small handle so the entire locking device can be pivoted together with the actuator plate so that the tooth comb out of engagement with the opposite toothed belt.
  • This handle forms a relatively long lever arm to the horizontal pivot axis.
  • Tooth engagement with the locking device is located on the opposite webbing.
  • Figure 1 Top view of a snap closure according to the invention
  • FIG. 2 section according to the line III-III in FIG. 1
  • Figure 3 a half section of Figure 1 according to the line Ill-Ill in perspective view
  • Figure 4 an enlarged section through the locking device
  • FIG. 5 side section through the latching device according to FIG. 4
  • FIG. 6 Operation of the latching closure during one-handed pushing together of the latching device
  • Figure 7 Operation of the locking device in one-handed release of the locking device in the sense of a release movement
  • Figure 8 one-handed releasing locking device on the front of the actuator plate
  • FIG 1 two opposing straps 1, 2 are shown, wherein the webbing 1 is material integral with a toothed belt 3, which has locking teeth 17. At the front end of the toothed belt 3 an insertion bevel exhibiting stop 18 is formed.
  • the opposite webbing 2 is materially connected to a detent device 4, which consists of an upper actuating plate 6, are connected to the lateral front and rear connecting walls 7 material integral. These connecting walls 7 merge into a foot plate 8 and on the underside of the foot plate 8 a tooth comb 9 with a number of locking teeth 21 (see FIG. 4) is arranged on the front pivotable part of the locking device 4.
  • the opposing teeth 17, 21 of the tooth comb 9 and the toothed belt are not arranged in each case on the end sides, but on the broad sides, so that form very long tooth flanks, which are high load-transferring engaged.
  • Figure 1 shows that in the area of the base plate 8 directed forward, open slots 10, 11 are present, which separate the base plate 8 laterally adjoining side walls 12.
  • the rear portion of the foot plate 8 is elastically bendable connected to the side walls 12, while the front portion is separated by the forwardly open slots 10, 11, so that the entire inner portion of the locking device with the actuating plate 6, the connecting walls. 7 and the foot plate 8 is formed spring-loaded about said pivot axis 33 pivotable.
  • Each side wall 12 continues forward and backward by guide lugs 13, which overlap a portion of the toothed belt 3 and thus form an extended longitudinal guide.
  • the ratchet teeth 17 of the toothed belt then come into toothed engagement with the associated ratchet teeth 21 of the tooth comb 9 of the locking device 4, and further overlap the guide lugs 13 front and rear at least partially the toothed belt 3, so that in this way a low-friction longitudinal guidance of the toothed belt is ensured in the locking device 4 ,
  • the toothed belt 3 has a number of latching teeth 17 and is limited at the rear end by a handle 5, which serves as a finger counter bearing in the operation of the latching closure.
  • FIGS. 4 and 5 show further details of the latching device 4.
  • the locking teeth 17 of the toothed belt 3 have a toothed slope 22 which is inclined at an angle 23 to the horizontal.
  • the ratchet teeth 21 are aligned on the tooth comb 9 of the locking device 4.
  • FIG. 4 also shows that the actuating plate 6 is designed as a one-armed lever, since the plate surface 30 required for actuation is arranged as a one-armed lever beyond the pivot axis 33 in order to ensure that, when pressure is applied to this plate surface 30, the front part of the actuating plate 6 so that the front side wall 7 pivots with the tooth comb 9 in the direction of arrow 29 upwards.
  • FIGS. 6 to 8 now show different types of actuation for the latching closure according to the invention.
  • an exemption 20 is present, from which the entire locking device 4 is formed upwardly out of material ein Cultureig in a corresponding injection molding tool.
  • FIG. 6 shows how with two fingers 27, 28 of a hand a change in length takes place in the sense of a shortening of the straps 1, 2.
  • one finger 27 is touched on the handle 5, while the opposite finger 28 is touched on the handle 31 and thus the locking device 4 is spring-loaded pivoted upward in the direction of arrow 29, so the tooth comb 9 out of engagement with the To bring toothing of the toothed belt 3.
  • the shutter can then in the direction of arrow 24th (Pulling direction) are moved against the handle 5.
  • the distance between the straps 1 and 2 is reduced.
  • the operating mode according to FIG. 7 applies. It is again attacked with a finger 27 on the other side of the handle 5, and the opposite finger 28 now acts on the plate surface 30 as an enlarged lever arm. which in turn the entire latching device 4 is spring-loaded about the pivot axis 33 in the direction of arrow 29 is pivoted upwards. So it is sufficient a simple finger pressure on the lever-like plate surface 30 in the direction of arrow 32 to bring the entire assembly in the open position, because thus the webbing 1 is pulled out in the direction of arrow 24 from the locking device 4 and thereby increases the distance between the straps 1, 2 becomes.
  • FIG. 8 shows a second possible application such that attacking the handle 31 also pivots the detent device 4 in the direction of arrow 29, thereby dislodging the toothed comb 9 from the toothed belt 3, which in turn achieves an open position, ie an extension between the straps 1 and 2.
  • the extension of the head width can thus take place either after the operating mode of Figure 7 or 8.
