Description
The present invention relates to a kind of interior locking of protective helmet helmet shell or device of guiding mechanism handled, it realizes hanging, lock, thread off or adjusting of chinstrap by means of a push pedal that easily touches toward the outside on the helmet shell.This manipulation device is specially adapted to Motor-cyclist's crash helmet or untiing and snapping of protective helmet chinstrap.In the helmet shell that closes that constitute by several parts or removable, must handle connector arrangement by a device from the outside, for example untie or lock.
In the existing guiding mechanism or retaining mechanism that is fixed on helmet side, be provided with breach in the side of helmet helmet shell, the pull-button that easily touches or the snapping or the guiding mechanism of push button control chinstrap are arranged in breach.Since require this safety devices to be easy to touch, for example often must be with operating with the thumb of gloves, and the opening on the helmet shell will have suitable size.
This just produces the following shortcoming in practice:
1). when running at high speed, produce very strong noise, even the infringement sense of hearing.
2). the openning of being opened on the helmet is difficult to sealing to prevent to infiltrate moisture.
3). for easy operating, this operating means must be made the form of groove, and produces the danger of being hooked can not prevent to overturn fully under with the situation of certain groove shape operating means the time.
The task that the present invention will solve provides a kind of manipulation device that is used for this locking and guiding mechanism, and its mode of operation is simple, does not have side opening on the helmet shell, in the state of accident also easy operating and can avoid above-mentioned shortcoming.
This task is solved by following device: be used to handle locking or guiding mechanism in the helmet shell that is contained in protective helmet, realize by means of the push pedal on the helmet shell that easily touches from the outside the retaining mechanism of that constitute by several parts and the removable helmet shell that closes of chinstrap or the device that hangs, locks, threads off and adjust, it is characterized in that, push pedal in helmet shell neck ring scope preferably is installed in the side of the helmet with the form of one, like this its surface when inactive state and the surface of helmet shell keep continuity; Having provided it by following description constitutes and the possibility of implementing: according to described device, the push pedal in the neck ring scope of helmet shell can be pushed in guiding device; For the guiding of push pedal (4), in its size and the corresponding breach of push pedal, bootstrap block is being housed on the edge of helmet shell; The shape of bootstrap block makes the type limit of the neck ring lower edge in the neck ring scope to insert bootstrap block from the side under the situation of moulding to connect; Bootstrap block has constituted the construction unit that is made of plastics with the type limit of neck ring lower edge; Its neck ring edge is equivalent to a segment distance of bootstrap block thickness with respect to the helmet shell indentation on top, thereby makes that its outer surface forms a continuous face that does not have bossing under the situation of the bootstrap block that has push pedal of packing into; Bootstrap block on helmet shell inboard has a bullport, and push pedal can be moved in vertical direction in this hole; Bullport is intilted from bottom to top in the helmet, and corresponding bending is also done in push pedal, is to be in the exterior contour of helmet shell when its inactive state thereby make the front end face of push pedal; Lower edge as the push pedal of pushing face flushes with the base of neck ring edge or its moulding; For the direct manipulation locking of chinstrap and the push pedal of guiding mechanism are hinged; For by locking of push pedal indirect operation or guiding mechanism, be provided with a fork or similar parts; But push pedal adopts the structure of two bars to make its maintenance swing state in its guiding device, and control surface flushes with the helmet casing krofile in inactive state like this; Push pedal is being supported swingably by one-sided; Push pedal is to guide with a kind of slide plate guider in bootstrap block; The gathering sill of slide plate guider is to constitute like this, guarantees on control run that promptly push pedal at first is self to move, and then leads with being tilted.
According in the manipulation device provided by the invention, the push pedal of operation usefulness is not to be contained in helmet shell-side face and to be contained in the scope of lower edge, mainly is the lower edge in the neck protection district.Push pedal is contained in sidewall one side outwardly, and it constitutes and appearance makes the surface of in this zone helmet shell and the shape that is positioned at the helmet lower edge at this place keep continuously and not have the protrusion of breach or danger to a great extent.
According to very favorable constructive method, push pedal forms an integral body with the marginal zone, its installing make it when being pushed, shift to helmet shell the inside and when inactive state the outer surface of the exterior contour of helmet shell and the push pedal one that is kept perfectly.
In order to realize this purpose with very easy method, the another kind of structure of design has a bullport in the helmet shell according to the present invention, sees that from bottom to top when inner helmet, this hole is intilted.Push pedal itself will be done corresponding bending, so that the outside of push pedal is positioned at the surface of helmet shell when inactive state, when it is promoted, inwardly be directed and move up, and correspondingly on its operated locking fastening device and adjustment component, work according to the guide surface that tilts.
To the guiding of push pedal, another structure of design can adopt a kind of slide plate guider according to the present invention, is having guiding groove that guide pin is then arranged in push pedal on the bootstrap block in this device in bullport in replacement.Push pedal can be directed inwards in this embodiment, and along with its its angle of stroke is also different.
According to another embodiment, handle is made the form of two bars in bullport, is being supported in the mode that can swing, when handle overturns the part in helmet shell the inside is worked, and becomes the push pedal lateral surface of an integral body then outwards to be pulled out with the helmet hull shape.In this scheme, under the inactive state surface of helmet shell in the marginal portion equally without any bossing.
The structure favourable according to another kind, the lateral junction of the anti-mask of the bootstrap block of push pedal and neck lumps together, and has saved the measure that is used for specially being fixed on the helmet shell with construction unit of its formation like this.The injury that fixed part (rivet) may cause can further be reduced in the back when overturning or similar accident take place in this way.
Below, the present invention is illustrated in conjunction with relevant accompanying drawing according to two embodiment.

Figure 19 is according to the sectional view of the manipulation push pedal that can outwards move of Figure 17,
Figure 20 is fixed on part in addition used on the helmet lower edge according to two kinds of Figure 17-19 possible push pedal swing modes with push pedal.
The chinstrap locking device that Fig. 1 has shown the protective helmet 1 that chinstrap guiding mechanism 2 is housed in the inboard or has the grafting tongue.The push pedal of handling locking device or guiding mechanism is worked on adjustment of not drawing in detail or retaining mechanism by action key 5.
Helmet edge 6 has openning for guide member 7 is installed in the scope of push pedal 4, guide member 7 has a corresponding holddown groove 8.Neck ring lower edge 9 is inserted into the guide member 7 from side 10.The push pedal with the rectangle shown in the section line is inserted in the hole 11 that has suitable movement clearance among the figure when assembling, and guide member 7 and neck ring 9 are bonded together with the helmet shell.
Fig. 2 shows push pedal 4, the locus of neck ring 9 and helmet shell, and Fig. 3 shows the perspective view of appropriate section.
In the structure that illustrates, the bottom 12 of handle 4 has recessed arc, and this is the measure of taking that makes things convenient for that is lifted for push pedal when the check steel ball that is 100 millimeters is tested is unlikely according to rules employing diameter.
In the resting position (helmet push pedal position in use) of push pedal, the be adjusted pushing of (reverse) spring force of mechanism's effect downwards of push pedal 4 with the arrow 13 of expression push pedal direction of action.At the exterior contour of this position helmet, comprise small bump and recessed portion 12 that the flange 15 of guide member 7 causes, be an integral body, like this since those shortcomings that in push pedal, occurred that the prior art level causes be eliminated basically.Just when speed is very high, on the outer rim 14 and 15 of guide member 7, also can produce some interfering turbulent flows.
For getting rid of this interference, according to aforesaid conceive according to the present invention the structure shown in Fig. 5-8 has been proposed further.The actuating element of push pedal and helmet shell remain one whole fully in this structure.
Fig. 5 shows a kind of being contained in and is inlaid in a push pedal 16 in the guide member 18 on the ad hoc neck ring 17 specially.Have an outer rim 20 with guide member 18 to have the low concave portion 21 of certain depth accordingly on the helmet shell 19, after neck ring assembled, guide member 18 and helmet shell 19 had just constituted a continuous surface like this.Push pedal 16 is from following, just from control surface 21 look up be turning-in and be subjected to a guiding with the R-joining 22 in gap.
When promoting push pedal 16, it makes progress and moves with corresponding angle 23 inwards.This moving must be considered tie point 24 in its stroke and guiding mechanism.
Locking must have one section little idle stroke (safe stroke) in this case with guiding mechanism.
The another kind of favourable structure possibility of operation push pedal has been shown in Fig. 9 to 13.In this structure, push pedal is the same in its inactive state and structure at Fig. 5 to 8, and helmet shell and neck ring all have on all four exterior contour.In addition, in this structure, push pedal 16 is contained in the ad hoc guide member 18 and slides therein.
In Figure 13, at length show the perspective view of single parts in guide member 18 structures.
Therefore each guide groove, upward and one angle α is arranged corresponding to the slit in the structure of Fig. 5 to 8 22 as shown in figure 10 with vertical direction, like this when operation push pedal 16 correspondingly sideling upwards action handle operating mechanism.Concerning some service condition, very advantageously be, very little at the angle α of beginning part guide groove and vertical direction, be α ' as shown in figure 12, then equally as shown in figure 12, the strain of angle phase is α greatly ".Thereby realized from an angle so just having determined the BENDING PROCESS of guide groove to the transition continuously of another angle.
By these measures guaranteed overturn or other abnormal conditions under, the pushing force (shown in arrow Z among Figure 10) that side direction is come can not make locking device thread off, it can only just move under from following thrust concerning push pedal 16.And can not run into from following power unexpectedly.
In the structure of Fig. 9, show the guide member of pressure-button with some sideshake.In fact it is necessary making it that some gap is arranged, in order to compensating operation error and assurance pressure-button easy operating.
For the possible vibration of eliminating the push pedal 16 that causes owing to blast when the high speed and the noise that produces therefrom, in selected structure, one breach 26 is arranged on handle 16, fixing lug boss 27 on bootstrap block 18 matches with it and as shown in the figure, in inactive state, a very little gap is only arranged between fixing lug boss and breach.Do not need on production technology special cost just can guarantee a very little gap on this position, because the diameter of fixing lug boss 22 is very little, thereby in fact vacant amount can neglect with other rigging errors.
Be equipped with in the inside of bootstrap block 18 and clamp dividing plate 28, making bootstrap block and the helmet is that the helmet shell clamps, and has nothing to do with the fixing of lower edge 9 of neck ring.
Push pedal itself can promote, and is provided with to promoting its necessary guiding device for this reason, and this structure for the manipulation device that up to the present the present invention provides is common.
The canting of the push pedal by having the respective guide device or swing also can realize the desired control action, in this case, also can keep continuous shape at the lower edge of inactive state helmet shell.
A kind of like this have the swing form of operational feasibility to be described in the relative section of Figure 14 to 16.Push pedal 31 is hinged on the pin 33 of corresponding bootstrap block 32 1 sides in this case.When operating from following thrust, push pedal 31 is swung and is moved upward along circular arc.In Figure 14, correspondingly be described with arrow 34.This motion can be thrown off the locking device of belt directly or indirectly.Clearly, bootstrap block 32 can be done very simply in this structure, and is the same with the structure of Fig. 2 to 4 certainly, can for example install a detachable cover cap additional by special measure, and the arris of bootstrap block in certain scope of helmet shell edge all eliminated.Directing pin adopts the structure that tilts also can reduce the influence of arris.
Structure when adopting dumpable push pedal is shown in Figure 17 to 20.In this structure, push pedal 35 is crooked as the structure of Fig. 5 to 8.The front end face of its control surface is embedded in the groove of corresponding bootstrap block 36 identically.
Therefore, according to designer's imagination, working method can be resolved like this, and the operating surface that is about to push pedal 35 inwardly pushes, so that impose control action on connector 39, as shown in figure 18.Perhaps the designer determines for control corresponding parts 40 are handled push pedal to be pulled outwardly from its resting position, and the pole of handle is left and swing inwards from the helmet shell like this, as shown in figure 19.
Within the scope of the invention, two kinds of measures have identical advantage, all are feasible.Wherein the mode that pushes inward of Figure 18 has a less additional advantage, that is to say that push pedal and bootstrap block are airtight and very close to each other on front end face, then must leave movement clearance in the structure of Figure 19, but be arranged with interference in the lower edge of the helmet.
Manipulation device of the present invention is concrete according to some, is described in fact very suitable structure possibility.As for the combination between push pedal and retaining mechanism or the guiding mechanism is known, and its structure need not be given unnecessary details.
Very clear for the professional who is engaged in professional work, transmission and method of operating in helmet shell inside in order to be suitable for power, the lever transition apparatus of between push pedal and locking and guiding mechanism, can packing into.The steering of push pedal can change slightly, and for example in the structure of Fig. 5 to 8, the guiding device of push pedal 16 has halt or dead point, only allows and threads off with a given minimum pressure.This formation is within the professional knowledge scope.
