The specific embodiment
In above-mentioned figure, the upper-turn-type helmet 1 according to the present invention has shell 2, and this shell is connected with the both sides of protecting jaw parts 3 by at least one fixed mechanism 5.Fixed mechanism 5 makes and protects jaw parts 3 and shell 2 can carry out relative motion.Preferably, this protective helmet 1 has a pair of fixed mechanism 5, and wherein each fixed mechanism all will protect jaw parts 3 and be connected with the respective side of shell 2.Each fixed mechanism 5 all have first Connection Element 10 that is connected with shell 2 and with protect second Connection Element 20 that jaw parts 3 are connected.Feature according to protective helmet 1 of the present invention is: each fixed mechanism 5 all has pair of axle spindles 11,12, and each wheel shaft all has the first end 11B, the 12B that are fixed in Connection Element 10,20 and insertion and is formed at the second end 11C in the corresponding rail plate 21,22 on another Connection Element.Rail plate 21,22 be configured as make wheel shaft 11,12 within it portion slide, thereby determine relative motion between second Connection Element 20 and first Connection Element 10.This motion makes that protecting jaw parts 3 can change closed condition into from open mode, and vice versa.
In other words, the relative motion between jaw parts 3 and the shell 2 is just protected in the relative motion between two Connection Elements 10,20 that produced by the slip of wheel shaft 11,12 in rail plate 21,22 separately.This relative motion is corresponding to protecting jaw parts 3 with respect to the moving up and down of shell 2, more precisely, and as the opening and closing of the protective helmet 1 of Fig. 1-shown in Figure 6.
Fig. 6 shows the protective helmet 1 that is shown in an open position after sliding in the corresponding rail plate of wheel shaft 11,12 at fixed mechanism 5.More particularly, continuous lines is represented according to the present invention to protect jaw parts 3 by what fixed mechanism 5 was connected with shell 2, and discontinuous line is to be illustrated in the identical jaw parts 3 residing positions of protecting under the supposed situation that adopts traditional mechanism.As can be seen, compare with traditional scheme, fixed mechanism 5 according to the present invention makes that protecting jaw parts 3 can be in lower position.Thereby according to the present invention, the drag force when protective helmet is opened is obviously reduced.
Protecting space littler between jaw parts 3 and the shell 2 also makes the center of gravity of the helmet 1 move on to the rear portion 2B of shell 2.So just avoided the neck effort, made head keep good locations simultaneously.
According to first kind of possible implementation, the wheel shaft 11,12 of fixed mechanism 5 has first end 11B, 12B, and this first end 11B, 12B are fixed on and are connected on second Connection Element 20 that protects jaw parts 3.Therefore, the rail plate 21,22 of two wheel shafts 11,12 all is installed on first Connection Element 10 that is connected in shell 2.As selection, such scheme also can be substituted by the conceptive scheme that is equal to of another kind, wherein, end 11B, the 12B of wheel shaft 11,12 is fixed on first Connection Element 10, another end 11C is inserted in the corresponding rail plate 21,22, and rail plate 21,22 is formed on and is fixed on second Connection Element 20 that protects jaw parts 3.
According to preferable configuration of the present invention, fixed mechanism 5 has one or more elastic components 81, this elastic component is set in the wheel shaft 11,12 at least one exerted pressure, at least when the helmet is in open mode, that is to say, change into from closed condition under the situation of open mode at the helmet, when wheel shaft 11,12 was determined the relative slip of retaining elements 10,20, this pressure made the wheel shaft 11,12 can reverse slide.In other words, elastic component 81 is installed as can stop when the helmet is opened and protects jaw parts 3 and drop downwards.
According to a kind of possible implementation of the present invention, fixed mechanism 5 has at least one tooth parts 31,32 is arranged, there are tooth parts 31,32 to be arranged near in the rail plate 21,22 at least one, and are fixed on the Connection Element 10 and 20 with rail plate.
This gear drive makes wheel shaft 11,12 become more stable in the slip of rail plate 21,22 inside.Meanwhile, gear connects and can reduce the negative influence that rubs between wheel shaft and the rail plate.Thereby improved the reliability of this fixed mechanism 5 and protective helmet 1.
Fig. 1 to Fig. 6 has shown first kind of embodiment according to protective helmet 1 of the present invention, this embodiment has tangible difference, because rail plate 21,22 forms wheel shaft 11,12 is slided in rail plate 21,22, thereby determine relatively rotating between second Connection Element 20 and first Connection Element 10.In fact this relatively rotates is exactly the rotation of protecting between the jaw parts 3 and the helmet 2, can be raised thereby protect the jaw parts, and the helmet 1 can be opened.Specifically, rail plate 21,22 forms, and in the sliding process of wheel shaft 11,12, produces the rotating shaft that the position continuously changes between two Connection Elements 10,20.This has just shown the difference of the present invention and prior art scheme, in existing scheme, protects jaw parts 3 and rotates around the rotating shaft of being fixed on the shell.According to the present invention, rotation is to carry out around the rotating shaft that moves in the space along a certain route, but not carry out around fixing physical axis.
As shown in Figure 1, in first kind of implementation method, rail plate 21,22 is along equal in length and the different circular arc of radius of curvature forms.Specifically, rail plate 21,22 is provided with orientation each other in the following manner: a rail plate is with respect to the arc that is formed centrally protrusion in another rail plate.
As shown in Figure 1, Connection Element 10,20 is provided with in the position that limits rail plate 21,22 and near described rail plate tooth parts 31,32 is arranged.More particularly, according to the embodiment of the present invention, in each rail plate 21,22, fixed mechanism 5 has and is fixed in first on the Connection Element 10,20 that has rail plate and has tooth parts 31 and second that tooth parts 32 are arranged.
As shown in the figure, tooth parts 31,32 are arranged to be located at position along the mode of same curvature radius near guide rail 21,22.More particularly, first has tooth parts 31 (its arc length is less than the arc length of rail plate 21,22) to be arranged at the shorter length side of guide rail 21,22 abreast, and second has tooth parts 32 (its arc length is greater than the arc length of rail plate) then to be arranged at the longer side of rail plate abreast.Have tooth parts 31,32 and rail plate 21,22 highly different, thereby after wheel shaft passed the rail plate insertion in advance, first gear 41 and second gear 42 that are installed on the wheel shaft 11,12 can freely rotate around wheel shaft.
Pass in the process of guide rail 21,22 slips at wheel shaft, gear 41,42 can both freely rotate around wheel shaft 11,12, as previously mentioned, makes the relative motion between the Connection Element 10,20 stable, and has reduced the sliding friction effect.
As mentioned above, fixed mechanism 5 preferably uses spring 81, and torsionspring for example, this spring one of are installed in the Connection Element 10,12, and operating side 53 one of is connected in the wheel shaft 11,12.As mentioned above, the advantage of this scheme is the change of having considered wheel shaft 11,12 glide directions, and another advantage is to make the relative motion of Connection Element 10,20 stable.
Fig. 2 is the exploded view of said fixing mechanism 5, wherein can see the details of all above-mentioned parts.As can be seen from the figure, rail plate 21,22 all is arranged on first Connection Element 10 that is fixed on the shell 2, and slip wheel shaft 11,12 all is fixed on and is fixed on second Connection Element 20 that protects on the jaw parts.On scheming, also can find out have tooth parts 31,32 and/or slip wheel shaft all can form single-piece with its respective fixation part that must fix.
Shown in the exploded view of Fig. 2, the Connection Element 10,20 of fixed mechanism 5 preferably make with shell 2 with protect the element that jaw parts 3 separate, be assembled in the cavity 88 afterwards and be fixed on the appropriate section of the helmet 1 (protecting jaw parts 3 and shell 2).This makes fixed mechanism 5 to be made by the material different with the material of making the helmet 1 other parts, thereby the manufacturing of the helmet is more prone to, as spraying process.Certainly, these elements that constitute fixed mechanism 5 can be made by plastics self-lubricating materials such as for example Teflons.Utilize this material or other analog materials can avoid possible clamping stagnation, it is functional thereby improve.This only is wherein a kind of feasible method, and these parts can be made by any other material.Simultaneously, we must consider following possibility: make Connection Element 10,20 and protect jaw parts 3 and to make single-piece with shell 2, vice versa.
Fig. 1,3,4,5,6 has sequentially shown the gear position in wheel shaft sliding motion process, can easily understand the operation principle according to fixed mechanism 5 of the present invention like this.
Fig. 7 to Figure 10 relates to second kind of embodiment according to the helmet 1 of the present invention.The characteristics of second kind of embodiment are different with the front, wheel shaft 21,22 manufactures wheel shaft 11,12 and slides in rail plate, thereby determines the initial rotation of first Connection Element 10 with respect to second Connection Element 20 between first operating position (helmet closed position) and centre position (helmet partially opens the position). Rail plate 21,22 forms and makes this initial rotation that first Connection Element 10 is moved along a straight line with respect to second Connection Element 20, up to the final position (helmet open position).
Fig. 8 is the exploded view of the fixed mechanism 5 of second kind of embodiment according to the present invention.As mentioned above, wheel shaft 11 and 12 is fixed on second Connection Element 20, and passes the corresponding rail plate that is formed on first Connection Element 10 and insert.
As shown in Figure 7, first rail plate 21 is made of the first curved portion 21B and the second straight line portion 21C.Another rail plate 22 linearly and with the straight line portion 21C of first rail plate 21 aligns.First rail plate 21 forms along a concave, and it is centered close to shell 2B and protects between the jaw parts 3.In other words, the contour shape of first rail plate is a hook-type and to the front end 1B of helmet projection.
According to the possible implementation shown in the figure, the profile of first rail plate is that first curvature radius is greater than second curvature radius.The protrusion degree of first arc 21 should be more outstanding than the front outline 17 of the helmet.
The helmet under Fig. 7 has shown in off position, as can be seen from the figure wheel shaft 11,12 is positioned at the first of rail plate.When protecting jaw parts 3 application of forces, 11 beginnings of first wheel shaft are moved in first rail plate 21 the user, but second wheel shaft 12 still rests on an end of rail plate 22.In other words, carry out the starting stage of relative motion between Connection Element 10 and 20, second wheel shaft 12 has been determined the center of rotation of element 10 and 20.
As mentioned above, before element 20 arrives mid portion, all be this situation, at the place, centre position, because second rail plate 22 aligns with the straight line portion 1C of first rail plate 21, rotatablely moving has become the rectilinear motion (see figure 9).Therefore, 12 beginnings of second wheel shaft are inner mobile at second rail plate 22, thereby finish relatively moving between two Connection Elements 10 and 20, to realize opening the helmet, (see figure 10).
Figure 10 is presented at the helmet 1 under the open mode.More particularly, continuous lines is represented to protect jaw parts 3 by what fixed mechanism 5 according to the present invention was connected with shell 2 among the figure, and discontinuous line is illustrated in the identical jaw parts 3 residing positions of protecting under the supposed situation that adopts traditional mechanism.As can be seen, compare with the rotational structure of conventional fixed, fixed mechanism 5 according to the present invention makes that protecting jaw parts 3 can be in lower position.Particularly, in second kind of embodiment, can obtain than first kind of effect that embodiment is better.These all are to protect jaw parts 3 more close shells 2 because the motion of element 10 and 20 can make.
In this embodiment, fixed mechanism 5 is provided with at least one tooth parts 31, and this has tooth parts 31 adjacent with first rail plate 21 and have a crooked profile.This has the tooth parts to contact with the gear 41 that is fixed on wheel shaft 11, and according to aforementioned purpose and function, wheel shaft 11 has plugged by rail plate.
According to preferred implementation of the present invention, fixed mechanism in second kind of embodiment has used spring 81, this spring is installed on the Connection Element, makes operating side 53 be fixed on second wheel shaft 12, and second wheel shaft 12 plugs on second rail plate 22 with outline of straight line.
In second kind of embodiment, spring 81 has embodied very big advantage.During Connection Element 10 and 20 rotated, spring had been avoided the counter motion of wheel shaft 11 and 12, and carried out straight line when moving at Connection Element 10 and 20, made rectilinear motion be more prone to, and the helmet is easier to be opened thereby make.
The upper-turn-type helmet 1 also has a vizard, and this vizard is hinged by the fixed rotation point that is positioned at shell 2 relative positions, both sides.Specifically, this vizard is hinged on any that does not belong to any Connection Element 10 and 20, and Connection Element 10 and 20 formations can make protects the fixed mechanism 5 that the jaw parts rotate.These mechanisms can be provided with halt system, and in the helmet 1 opening procedure, this halt system makes vizard near protecting jaw parts 3, thereby avoids shell to be swiped, and perhaps generates more drag force.
The technical scheme that this upwelling type protection helmet adopts can thoroughly solve former fixation problem.Specifically, in two kinds of technical schemes, the upper-turn-type helmet can both reduce to protect the space between jaw parts and shell, thereby has reduced the drag force of the helmet.Verified, it all is feasible being used for protecting two kinds of mechanisms that the jaw parts are fixed on the shell, has reduced the quantity of parts like this, and has been easily mounted on the protective helmet.
Can carry out various changes and variation to the helmet of making in this manner within the scope of the invention, full details can adopt other equivalent arrangements.
In the practice, employed material and size and dimension can be changed with the prior art level as requested.
The scope that above-mentioned notion or all possible change that is equal to mechanism all are positioned at the present invention to be protected.
