Definitions

  • the invention relates to a closure device for the chin strap on a protective helmet, motorcycle protective helmet or the like. According to the preamble of claim 1.
  • a generic closure device is known from US-A 2 867 812.
  • a latching piece Arranged on each narrow side of the closure section is a latching piece which can be pivoted about an axis and which, after a corresponding pivoting movement, engages in the toothing of the closure section arranged in the longitudinal direction.
  • Another known closure device (DE-U 83 24 458) has a locking piece which is arranged above the broad side of the closure section and which has one in the broad side the locking section arranged toothing cooperates.
  • the locking piece is pressed onto the closure section by a spring so as to achieve a latching of the closure section in the release direction of the chin strap. If a force acts on the chin strap in the release direction, the locking piece is pressed more strongly onto the closure section, as a result of which bruises and permanent deformations of the closure section cannot be ruled out.
  • the arrangement of the locking piece above a broad side of the closure section leads to a considerable overall height, so that when arranged in the helmet shell, the inner padding in the area of the mortise lock is relatively thin compared to the other areas. In the event of an accident, a risk of injury from the mortise lock cannot be excluded.
  • the invention is based on the object of designing the closure device for the chin strap of a protective helmet in such a way that its easy opening remains ensured even after large tensile forces act on the closed closure device.
  • a locking device is created which reliably prevents deformation in the mortise lock even after the greatest tensile forces act on the locking section, so that also after an accident an easy release of the locking device is ensured. This ensures that after loosening the fastener section, the chin strap can be removed and the helmet can be easily removed from the head of the injured person without endangering his health and life. Essentially only shear forces act on the closure section, which makes it possible to optimally dimension the surrounding components.
  • the small overall height of the mortise lock according to the invention ensures, when arranged in the helmet shell without structural changes, a sufficiently thick padding in the area of the mortise lock, so that the risk of injury is reduced.
  • the mortise lock is essentially composed of two housing halves, a receiving groove forming the receiving channel being provided in one housing half and the locking piece being guided and supported. All force-transmitting elements of the closure device are thus in one housing half, whereby jamming of the actuation mechanism is reliably avoided.
  • the closure section is provided with a stop part which interacts with a stop provided on the helmet shell or the mortise lock in order to limit the insertion movement.
  • the locking recesses on the chin strap are arranged at such a distance from the stop part that it only locks when the stop part is put against the stop. This eliminates the latching noises that otherwise occur during insertion until the desired insertion position is achieved.
  • the chin strap is expediently designed to be length-adjustable between the closure section and its other end fixed on the helmet shell in order to adjust it according to the requirements of the user. However, this setting only needs to be carried out once, since the user then pushes the locking section in as far as it will go and the locking noise that then occurs reliably indicates the locking of the locking section.
  • the protective helmet shown schematically in FIG. 1 and in perspective in FIG. 2 consists of a helmet shell 1 with an inner pad 10.
  • the protective helmet is held on the head of a user by means of a chin strap 4, one end 13 of which is connected to an end fitting 2 by means of a rivet, a screw or the like is fixed on one side of the helmet shell 1.
  • the other end 11 of the chin strap 4 is held in a chin strap adjustment 12, to which an especially dimensionally stable closure section 14 preferably connects in one piece.
  • the closure section 14 can expediently be made in one piece with the chin strap adjustment 12 from a preferably reinforced plastic.
  • the locking section 14 is guided and held on the side of the helmet shell 1 opposite the end fitting 2 in a mortise lock 5, which is attached to the helmet shell under the inner padding by means of screws 6 or the like 10 is attached.
  • an end 8 of a handle designed as a lever 7 protrudes from the housing 9 of the mortise lock 5.
  • the end 8 is articulated to a button 15, which is embedded in the neck ring profile 16 of the protective helmet in a corresponding guide 18.
  • the button 15 By depressing the button 15 in the direction of arrow 17, the lever 7 is pivoted about its bearing base 20 supported in the housing 9 in the direction of arrow 22 and takes an especially wedge-shaped locking piece 34 against the force of a helical spring 43 from the engagement position shown on the closure section 14 into an disengaged position .
  • the structure of the mortise lock 5 according to the invention results in detail from the exploded view according to FIG. 4, its mode of operation in connection with the locking section 14 from the views of FIGS. 5a to 5e.
  • the housing 9 of the mortise lock 5 consists of exactly two housing halves 30 and 31, which are joined together by means of screws 32, rivets or the like.
  • screws 32, rivets or the like In addition to such a releasable connection, welded connections, adhesive connections or the like can also be used.
  • the first housing half 30 there is a receiving groove 33 which, after being covered by the second housing half 31, forms the receiving channel 23 (FIG. 5b).
  • a locking piece 34 is arranged in a narrow side of the receiving groove 33 and can be displaced in the longitudinal direction of the receiving groove 33 is guided and held in the first housing half 30.
  • the locking piece 34 is guided such that it is simultaneously displaced transversely to the receiving groove 33 in the event of a longitudinal displacement.
  • the locking piece 34 on the side facing the first housing half 30 has a guide strip 35 which engages in a guide groove 36 in the first housing half 30.
  • the guide groove 36 forms an acute angle 38 of preferably about 30 ° with the longitudinal axis 37 of the receiving groove 33 (FIG. 5d).
  • the locking piece 34 is beveled along the guide bar 35 arranged at the appropriate angle to the receiving groove 33, the edge of the locking piece forming a guide surface 39 together with the wall of the guide bar 35, to which a corresponding counter surface 40 in the first housing part 30 is assigned, which is parallel to the guide groove 36 .
  • the latching piece 34 has a stop surface 41 at the tapered, front end, to which a corresponding stop 42 in the first housing half 30 is assigned.
  • the locking piece 34 held in the guide groove 36 and also supported on the counter surface 40 rests against the front housing stop 42 under the force of a helical spring 43; the stop 42 determines the engagement position of the locking piece 34.
  • the helical spring 43 lies in a longitudinal groove 44 arranged approximately parallel to the guide groove 36 in the first housing half 30 and is supported with one end in the housing half 30 and with the other end on the locking piece 34.
  • the other end lies in a countersink 45, which is provided on the locking piece side facing away from the stop surface 41.
  • the longitudinal groove 44 extends in the engaged position of the locking piece 34 to under the countersink 45, which is laterally open to the longitudinal groove 44 and together with this includes the other end of the coil spring 43. In this way, a secure mounting of the coil spring for applying a spring force in the longitudinal direction of the guide groove 36 is ensured.
  • the locking piece 34 lies approximately in the plane containing the longitudinal axis 37 of the receiving groove 33, which is largely parallel to the parting plane 25 (FIG. 5b) of the housing halves 30 and 31.
  • the latching piece has on its longitudinal side delimiting the receiving groove 33 a toothing 46 which, in the engaged position of the latching piece 34, projects into the receiving groove 33 via the longitudinal side 24 (FIG. 5c).
  • the locking piece 34 has a pin 47 projecting beyond the parting plane 25 (FIG. 5b) in the direction of the second housing half 31, which pin lies perpendicular to the level 19 of the locking piece.
  • the pin which is preferably provided in one piece with the locking piece 34, is provided for engaging in the bore 48 of the handle designed as a lever 7, which is mounted lying in a recess 21 on the other side of the parting plane 25 in the second housing half 31 lying transversely to the receiving groove 33.
  • the lever 7 is formed at one end as a rounded bearing foot 20, while its other end 8 has an opening 49 into which a connecting pin 15a of the push button 15 engages on one longitudinal side of the receiving groove.
  • the button 15 is held in its starting position by the spring force of the helical spring via the connection to the handle 7 and the locking piece 34.
  • the rounded bearing foot 20 lies on the other longitudinal side of the receptacle with a correspondingly designed bearing section 50 of the recess 21, which for the rest has the width of the pivoting movement of the lever 7 is adjusted.
  • the recess 21 is formed with an open end 51, from which the actuating end 8 of the lever 7 protrudes.
  • the handle 7 is protected in the housing of the mortise lock, so that, in particular in the event of an accident, forces do not act on the actuating mechanism and can damage it.
  • the assembled mortise lock 5 results from FIGS. 3, 5a and the section according to FIG. 5b.
  • the receiving channel 23 formed by covering the receiving groove 33 is provided for inserting a locking section 14, 14 'or 14' which is adapted in size and thickness.
  • the closure section 14 has on its narrow side 26 facing the locking piece a toothing 27 which is intended for locking with the toothing 46 of the locking piece 34.
  • the locking teeth 27 can be arranged over the entire length of a narrow side 26 or on both narrow sides of the closure section 14 '.
  • the toothing 27 is provided only over a partial length of the closure section 14; a toothless section 55 connects to the free end.
  • the closure section 14 ⁇ is provided with a stop which limits the insertion movement.
  • a closure section 14 To insert a closure section 14 in the correct position, it can have, for example, a guide pin 28 on the side facing the first housing half 30, which engages in a longitudinally extending groove 29 which is open at both ends and which extends in the broad side of the receiving groove 33 in the first housing half 30 is incorporated.
  • a guide pin 28 On the side facing the first housing half 30, which engages in a longitudinally extending groove 29 which is open at both ends and which extends in the broad side of the receiving groove 33 in the first housing half 30 is incorporated.
  • the serrations 27 and 46 engage in one another, so that the closure section 14 is locked in the receiving channel 23 and is thus held securely in the mortise lock 5.
  • the stop 42 is arranged in the housing 9 so that the teeth 46 of the locking piece 34 engage securely in the teeth 27 of the closure section, but no transverse forces can be applied to them.
  • the position of the locking teeth relative to one another is selected so that the locking teeth can easily engage for locking when inserted and a relative path required for opening is available.
  • the forces acting in the release direction 53 are transmitted to the locking piece only via the teeth in the longitudinal direction of the locking section and are safely derived via the stop surface 41 of the locking piece to the stop 42 in the first housing part 30 without the lever 7 or the pin 47 of the locking piece strain. A jamming of the lever mechanism is therefore reliably excluded.
  • the teeth 27 of the closure portion 14 and 14 'and the teeth 46 of the locking piece 34 lie approximately in a plane 19 (Fig. 5b), so that only the shear forces acting in the plane of the closure portion act on the material of the closure portion. Forces acting transversely to the plane of the closure section do not occur.
  • FIGS. 3, 4 and 5c to 5e The preferred configuration of the closure section 14 is shown in FIGS. 3, 4 and 5c to 5e.
  • a tooth-free section 55 which has a length which is preferably greater than that of the locking piece 34 or its teeth 46.
  • the closure section 14 on the toothed narrow side 26 is reduced in width by the height H of the toothing 27. Only the end section 56 of the narrow side 26 lying at the free end 54 of the closure section 14 lies at the level of the tips of the latching teeth, so that a shoulder 57 is formed between the toothless section 55 and the free end 54 of the closure section 14, which - as shown in FIG. 5e shows - cooperating with the locking piece 34 as a path-limiting stop 58.
  • the guide pin 28 is first threaded into the groove 29.
  • an insertion funnel 59 is attached to the entrance of the receiving channel 23.
  • the stop 58 With further movement in the direction of insertion 52, the stop 58 first pushes the locking piece 34 back in the direction of insertion 52, as a result of which the teeth 46 are simultaneously withdrawn transversely to the direction of insertion. In the region of the toothing-free section 55, the latching piece 34 jumps back into the engagement position shown, without latching being possible.
  • a safety attachment 75 which is formed in one piece with the locking piece, is provided, which is approximately perpendicular to level 19 and over the parting plane 25 extends up to lever 7. From this it is taken along in the release direction.
  • the actuating end 8 of the lever 7 is designed as a button 15 'which can be actuated by a recess 18' in the neck ring profile 16 of the helmet shell.
  • This one-piece design of lever 7 and button 15 ' reduces the number of moving parts and is therefore for simple helmet types, such as Jet helmets particularly suitable.
  • the groove 29 for the guide pin 28 of the closure section 14 is closed at its lower end facing the neck ring profile 16.
  • the closure section 14 can therefore only be pulled out of the mortise lock 5 until the guide pin 28 bears against the closed end 29 'of the groove 29.
  • the closure section can be pivoted about the guide pin 28, for which purpose the closure section has a cutout 14a in the entrance region of the receiving channel 23. The user can swing the chin strap forward out of the chin area and pull the helmet off his head.
  • the exemplary embodiment further shows that the first housing half with the force-absorbing components can advantageously be integrated in the home shell 1, in particular in one piece with it (FIGS. 6b, 6c). This results in a further possible reinforcement of the padding in the area of the mortise lock.
  • the mortise lock 5 is in turn fastened on the inside of a helmet shell 1 and can be actuated via a button 15 mounted in a guide 18 in the neck ring profile 16.
  • the button 15 has a bore 62 (FIG. 8) into which a connecting pin 63 of the lever 64 engages.
  • the lever 64 By pressing the button 15, the lever 64 is pivoted about the pin 60 into its disengaged position, so that the locking section 14 can be pulled out in the release direction 53 until its guide pin 28 engages in the longitudinal groove 29 closed to the input opening of the mortise lock 5 and at the closed end of the Longitudinal groove comes to rest.
  • the chin strap 4 is now loosened so far that the user can pivot it and remove the helmet.
  • the chin strap adjustment 12 which is preferably integrally formed on the closure section 14, is provided as a stop for the movement in the insertion direction 52.
  • the locking section is pushed into the lock 9 until a stop surface 67 of the chin strap adjustment 12 comes to rest on the lock or helmet and limits the insertion path.
  • the locking lever 64 has fallen into the toothing 27 arranged on the narrow side of the locking section 14 and locks the locking section 14 in the release direction 53.
  • the position of the toothing 27 is provided such that it only comes in when the locking section 14 is pushed in as far as the stop 67 in locking connection can occur with the locking lever 64. This has the consequence that only a locking noise occurs when inserting, namely when the Closure section 14 is fully inserted and the stop 67 z. B. at lock 9. No rest noises occur over the remaining displacement path.
  • a locking slide 70 is provided, which is displaceable at an angle to the locking section 14. If the closure section 14 is pushed in until the abutment surface 67 of the chin strap adjustment 12 bears against the abutment surface 68 of the lock 5 which forms the counter-stop, the toothing 46 of the locking slide 70 engages in the toothing 27 of the closure section 14.
  • a latching noise only occurs when the closure section 14 is completely, i.e. is pushed in until the stop of the chin strap adjustment 12 on the lock 5.
  • the closure section can be pulled out of the mortise lock 5 until the pin 28 abuts the closed end 29 'of the longitudinal groove 29.
  • the chin strap adjustment 12 is advantageously designed like a handle.
  • the webbing of the chin strap 4 is deflected in a known manner on a load-bearing clamping web of the chin strap adjustment 12 and is thereby clamped off.
  • the flexible webbing of the chin strap 4 is connected to the preferably dimensionally stable closure section 14 via the chin strap adjustment 12.
  • the individual adjustment of the length of the chin strap 4 thus takes place via the chin strap adjustment 12.
  • the chin strap 4 - as shown in FIG. 5d - is connected to the closure section 14 in an unadjustable manner.
  • the closure portion 14 ⁇ is preferably made of a metal-plastic combination.
  • a e.g. manufactured as a stamped metal tongue 80 forms the core of the closure portion 14 ⁇ .

  • the insertion tongue 80 is completely extrusion-coated with plastic, the end of the closure section 14 ⁇ opposite the grip area 82 being made flexible and thin-walled together with its stop pin 28 made of plastic.
  • the web 83 which can also be designed to be movable, is extrusion-coated in a rectangular cross-section with plastic (FIG. 11), so that the flexible chin strap which is pulled through is strongly clamped, thereby preventing an adjustment even under heavy loads.
