Definitions
- the invention relates to an arrangement for actuating a locking or adjusting device attached to the inside of the helmet shell of a protective helmet for hanging, locking, loosening or adjusting a chin strap by means of a handle which is accessible from the outside on the home shell.
- Such actuation arrangements are used to open or close chin straps on camber or. Shelters, preferably for motorcyclists. But even in the case of multi-part and / or hinged helmet shells, there is a need to actuate the locking device on the plug connection from the outside via an arrangement, eg. B. can release or lock.
- the object of the invention is to provide an actuation arrangement for such locking or adjusting devices which can be operated easily, which does not require any lateral openings in the helmet shell, which is nevertheless easy to use in the event of danger and accordingly does not have the aforementioned disadvantages.
- the hand is thus moved away from the side face of the helmet shell into the lower edge region, preferably by interrupting the neck end profile.
- the handle on the outward side is designed and shaped in such a way that the surface of the helmet shell is largely continued in this area or the end profile arranged there without forming recesses or dangerous cant.
- the handle can be integrated into the edge region in such a way that it is slidably arranged in the interior of the helmet shell, the outer contour of the helmet shell and handling surface being fully retained in the rest position.
- a guide opening is provided in the helmet shell, which is designed to be inclined inwards from the bottom upward into the helmet interior.
- the handle itself is cranked accordingly. ' so that in the rest position the outside of the handle lies in the surface of the helmet shell, while when shifting it can be guided inwards in accordance with the inclined guide surface and can be pushed upwards in order to suitably actuate the switching elements of the closure or the adjusting elements.
- a type of link guide can also be provided, in that guide grooves are provided in the guide piece and guide pins are provided on the handle.
- the handle can be guided inwards, even at different angles along the way.
- the guide piece for the handle itself can be connected to the neck end profile or even form a structural unit with it, so that special fastening measures on the helmet shell itself are not required. This measure further reduces the possible risk of injury in the event of a fall or the like through the fastening parts (rivets) themselves.
- FIG. L with a perspective view of a hard hat
- FIG. 6 shows a partial section corresponding to FIG. 5
- FIG. 9 is a top view of the handling area of a third embodiment
- FIG. 10 shows a section through the handle according to FIG. 9,
- FIG. 14 shows a plan view of the handling area with a handle which can be pivoted in
- FIG. 15 shows a section through the handle according to FIG. 14, 16 is an exploded view of the handle and guide piece,
- Fig. 17 is a plan view of the handling area of a fourth
- FIG. 18 shows a sectional illustration according to FIG. 17 when the handle is pivoted inwards from the rest position into the working position
- FIG. 19 shows a section according to FIG. 17 for a handle which can be actuated by an outward movement
- Fig. 20 the one-time parts for attaching the hand on
- FIG. 1 shows a protective helmet 1 with a chin strap adjustment device 2 arranged on the inside of a helmet or a chin strap lock with tongue 3.
- the handle for actuating the lock or the adjustment device acts on the adjustment or not shown Locking mechanism via an active connection 5.
- the helmet rim 6 is except in the area of the handle 4 for receiving a guide part 7, which has a corresponding fastening groove 8.
- the neck ring profile 9 is inserted laterally 10 into the guide part 7.
- the handle which is rectangular in cross section in the visible area, is passed through the opening 11 with a corresponding range of motion.
- Guide part 7 and neck ring 9 are connected to the helmet shell, for example by gluing.
- FIG. 2 shows the spatial assignment of handle 4, neck ring 9 and helmet shell
- FIG. 3 shows the corresponding part in a perspective view.
- the handle 4 is concave in the lower region 12. This is a measure to facilitate a test according to the regulation that the closure must not open when used with a test sphere with a diameter of 100 mm
- the handle 4 In the rest position of the handle (position of use of the helmet), the handle 4 is pressed downward against the actuating direction 13 by a spring force, which is accommodated, for example, in the adjusting mechanism. In this position, the outer contour of the helmet shell, with the exception of the slight elevations, is fully given by the edge rises 15 of the guide part 7 and the concave region 12, as a result of which also the handling according to FIG. the disadvantages shown in the prior art are substantially eliminated. Only at very high speeds do turbulences occur at the edges 14 and 15 of the guide part 7, which can be disruptive.
- Fig. 5 shows a handle 16 which is guided in a specially designed neck ring 17 with molded guide member 18.
- a recess 21 with a depth corresponding to the edge 20 is provided for the edge 20 of the guide part 18, so that after mounting the neck ring 17, the guide part 18 and the helmet shell 19 form a continuous surface.
- the handle 16 is from below, that is seen from the actuating surface 21, cranked inwards and guided with play in an oblique slot 22.
- the handle 16 When the handle 16 is actuated upwards, it moves according to the angle! 23 inside. This movement must also be taken into account in the movement play at the connection point 24 for the adjusting device.
- the handle 16 is formed in its rest position both at the bottom with the neck ring (not concave) as well as in the surface alignment of ⁇ , so that no more interfering edges are present.
- the locking or adjusting device must have a small lost motion (safety path).
- FIGS. 9 to 13 A further advantageous embodiment of such an actuating handle is clearly shown in FIGS. 9 to 13. Also in this embodiment, in the rest position of the handle, as in the embodiment according to FIGS. 5 to 8, there is an absolutely uniform outer contour of the helmet shell and the neck ring. In addition, in this embodiment, the handle 16 is held and guided in a specially designed guide part 18.
- the shape of the guide part 18 is shown in detail in FIG. 13 in a perspective view.
- the handle 16 is provided with guide pins 25 which slide in corresponding guide grooves in the guide part 18.
- Each guide groove can, as shown in Fig. 10, corresponding to the slot 22 in one embodiment according to the. 5 to 8 extend obliquely upwards in a straight direction at an angle c ⁇ with respect to the perpendicular, the handle 16 then being guided obliquely upwards when actuated to actuate the mechanism to be actuated.
- this angle o between the course of the groove and the vertical run very flat at the beginning as shown in FIG indicated with 0 * in Fig. 12.
- the transition from one angle to the other can take place continuously by choosing a curved course of the groove. This measure guarantees that, for. B. in the event of a fall or other irregularities, by pressing from the side, as indicated by the arrow Z in FIG. 10, the locking cannot be released, but only by pressing the handle 16 from below. A force from below cannot happen by chance.
- the guidance of the push button is shown with a certain lateral play. In practice, it seems necessary to allow a certain amount of play in order to compensate for manufacturing tolerances and to guarantee easy actuation of the push button.
- a recess 26 is provided in the selected embodiment in the handle 6, into which a fixing projection 27 engages on the guide piece 18 and which, as shown is designed so that in the rest position there is only very little play between the fixing attachment and the recess. At this point, little play can be guaranteed in terms of production technology without any particular effort, since the diameter of the fixing projection 22 is very small and therefore shrinkage and other manufacturing tolerances can be practically neglected.
- Kiemmstege 28 are provided in the interior of the guide piece 18 to the guide piece with the helmet or. to be able to jam with the helmet shell, regardless of the holder via the neck ring profile 9.
- FIGS. 1 to 16 A possible implementation with a pivoting movement is explained below in connection with FIGS. 1 to 16.
- the handle 31 is supported on one side on a pin 33 in the corresponding guide piece 32.
- the handle 31 is pivoted and moves upward on a circular arc. This is indicated in Fig. 14 by the arrow 34 accordingly.
- This movement can then be used directly or indirectly to release the lock or the lock for the belt, etc.
- the guide piece 32 can be constructed in a particularly simple manner, although, as in the embodiment according to FIGS. 2 to 4, "edges of the guide piece which extend beyond the helmet rim to a certain extent only by special measures how wegEnglish- face '. Atodeckept can be completely eliminated, even by an oblique arrangement of the guide pin, the Kan ⁇ be reduced th the effect.
- FIGS. 17 to 20 An embodiment with a handle that can be tilted in itself is shown in FIGS. 17 to 20.
- the handle 35 is cranked in a manner similar to that in the embodiment according to FIGS. 5 to 8. It thus fits flush with the front of its actuating surface into the recess of the correspondingly shaped guide piece 36.
- the handle 35 is open in this case; the rear of the guide piece, where two retaining lugs 37 are provided, is pivotably supported by means of a plug-in axis 38.
- the working position can vary depending on the designer's idea be triggered by the fact that the handle 35 on the surface Betuschists ⁇ is pushed inward, to exert a control movement to a switching ⁇ part 39, as clearly in. 18 or the constructor specifies that to actuate the correspondingly arranged control part 14 the handle is pulled out of its resting position, whereby the counter lever of the handle swings inward away from the helmet shell, as indicated in FIG. 19 .
- lever ratios can also be used for adjusting the force or actuation path inside the helmet shell between the handle and the locking or adjusting device.
- the direction of actuation of the handle itself can also be modified by, for example, in an embodiment according to FIGS. 5 to 8, the guide for the handle 16 is provided with a rest or dead center; in order to permit triggering only with a predetermined minimum pressure.
- Such configurations are in the area of specialist skill ⁇
