Definitions

  • the present invention relates to a safety helmet for protecting head, particularly to a safety helmet for the drivers of motor vehicles, especially the motor bikes, and more particularly to a safety helmet with changeable chin-guard structure.
  • a typical safety helmet usually comprises a helmet body, and a goggle, facemask and chin-guard which are mounted on the helmet body, wherein the goggle is used to protect eyes from hurt by sun shine or other strong light, the facemask is used to prevent the dust or like harmful particles from entering the helmet, and the chin-guard is used to effectively protect the chin of the driver in case of collision.
  • a conventional safety helmet usually includes two types: full face and open face helmets, wherein the chin-guard and helmet body of a full-face helmet are usually firmly connected with each other or even formed in one piece, in other words the chin-guard is fixed with respect to the helmet body, putting it this way the structure of the helmet is certainly simple and safe enough, but rather inflexible, for example, even when allowed by the environment, the user has to take off the helmet before doing drinking, calling, or other like actions; in contrast, the chin-guard of an open face helmet is movable, but usually a movable chin-guard only can reach around the top of the helmet body, meanwhile the chin-guard is in an open state, namely the china-guard is not able to cling to the helmet body, this position of the chin-guard can satisfy the requirements of the driver on drinking, calling and like, but meanwhile the driver should not continue to drive, even in a safe condition.
  • a Spain patent application ES2329494T3 discloses a helmet with structurally changeable chin-guard, comprising a helmet body, a chin-guard, two mounting plates, two moving pins and two fixed pins, wherein the mounting plates are symmetrically arranged on and firmly connected to the two sides of the helmet body as a whole, each mounting plate is provided with a grooved track formed by several grooved tracks connected, in addition the two holders of the chin-guard are respectively provided with grooved sliding rails, one end of each fixed pin is firmly fixed on the helmet body, the other end is penetrated into and moveably connected to the sliding rail on the corresponding holder of the chin-guard, one end of each moving pin is firmly fixed on the chin-guard, and the other end is penetrated into and moveably connected with the grooved track of the corresponding mounting plate, the most prominent feature of this technical scheme is that the position of its chin-guard can be flexibly changed according to need, namely the chin-guard can be raised from a full face position
  • the technology described above still has drawbacks, which mainly can be seen in that the perforated groove shaped sliding rails formed on the holders impair the strength of the chin-guard, as the perforated groove shaped sliding rails not only weaken the chin-guard in bending modulus, but also reinforce the tendency of stress concentration, the holders are thus easy to be broken in accident of collision; furthermore, the spacing of the fixed, and moving pins are various, when the chin-guard at the two travelling ends corresponding to the full face and open face helmet modes, as limited by the structure, the spacing of the fixed pins and moving pings must be small, the reliability and strength of the clinging of the chin-guard to the helmet body is quite weak.
  • the present invention provides a safety helmet with changeable chin-guard structure, with the purpose of allowing the chin-guard to change its position in relation to the helmet body, so as to achieve the structural shift between the full face and open face modes of the helmet, while effectively reinforcing the resistance to fracture of the holders of the chin-guard, and improving the reliability and strength of the clinging of the chin-guard to the helmet body.
  • a safety helmet with changeable chin-guard structure comprising a helmet body, a chin-guard with two holders, and two mounting plates arranged on the two opposite sides of the helmet body, the mounting plates and the helmet body being fixedly connected, or formed in one piece, characterized in that:
  • the tracks on the two mounting plates are symmetrically arranged in relation to the median plane of the helmet body.
  • Each of the tracks has two ultimate positions, including a starting position and an ending position, and for each track, the track plane of the portion of the track to the starting position or/and end position is gradually inclined.
  • the ending position and starting position of one of the two tracks of each mounting plate are completely or partially overlapped.
  • the two sidewalls of at least one portion of the tracks forms a gradually shrinking or/and expanding track width.
  • the mounting plates are provided with shrinkable grooves.
  • Each of the moving nails has a stepped journal structure, and the shoulder of the stepped journal is movably connected to the track plane.
  • the safety helmet further comprises a separator disposed between each holder and the corresponding mounting plate; the separators are moveably connected with the track planes of the tracks.
  • the separators and the moving nails are fixedly connected, or formed in one piece.
  • the separators and the holders are formed in one piece.
  • the separators are provided with through holes for the moving nails 5 to go through.
  • the moving nails are provided with recesses, engaged with clamping plates.
  • the safety helmet further comprises covers; the clamping plates are enclosed between the covers and holders.
  • One of the two tracks on the same mounting plate is configured in a closed loop annular track or an open loop arc track.
  • One of the two tracks on the same mounting plate is configured in a closed loop elliptical track or an open loop elliptical arc track.
  • One of the two tracks on the same mounting plate comprises a climbing, a crossing and a falling track.
  • the crossing track is an arc or an elliptical arc track.
  • the falling track is an arc or an elliptical arc track.
  • the climbing track is an arc or a straight line track.

  • the safety helmet further comprises road switching apparatuses arranged between the mounting plates and the helmet body, each of the road switching apparatuses comprises an elastic piece, comprising a sinking structure, a stopper and an elastic return structure.
  • the safety helmet with changeable chin-guard structure adopts a structural scheme of four moving nails cooperating with the tracks on the mounting plates, wherein the moving nails move with the chin-guard, through constraining the motion of the moving nails by the tacks formed on the mounting plates to define the motion trajectory of the chin-guard finally, so as to realize the function of changing the relative position of the chin-guard according to need, and to realize the structural shift between full face and open face helmet modes; and more importantly, in comparison with the prior art ES2329494T3 , as in the present invention the grooved sliding rails are no longer required on the chin-guard, the bending modulus of the chin-guard is enhanced, and thus the rupture strength of the chin-guard is improved, in addition, abandoning the structure of grooved sliding rails for the holders can effectively eliminate the hidden problems associated with stress concentration, and thus to reinforce the strength of the holders as well, in addition again, between the two moving nails connected to the same holder a longer and constant relative distance is always maintained, thus the
  • the safety helmet with changeable chin-guard structure disclosed herein comprises: a helmet body 1, a chin-guard 2 and two mounted patters 3, wherein the chin-guard 2 has two holders 2a, and are arranged on the two opposite sides of the helmet body 1; the most prominent feature of the present invention lies in that on each mounting plate two grooved tracks 41, 42 are formed, each which may be formed by one single grooved track (namely the entire grooved track is formed according to a same rule), or a multi-segment grooved track (namely the grooved track is a combined track consisting of several tracks formed according to different rules), as shown by Fig.
  • the track 41 is such an single track, but track 42 is formed by five sections connected, consisting of linear grooved tracks 42c, 42g, transitional grooved tracks 42d, 42f, and an arc grooved track 42e , but in Fig. 21 , the track 41 consists of several sections, while the track 42 has one single section only.
  • the helmet further comprises four moving nails 5 movable in relation to the mounting plates 3, wherein two of the moving nails 5, one holder 2a, and one mounting plate3 form an assembly and are mounted on a same side of the helmet body 1, one end of each moving nail 5 is fixedly connected, and thus moves with the holder 2a of the same assembly, and the other ends are penetrated into and moveably connected with the tracks 41 and 42 on the mounting plates of the same group respectively;
  • the mounting plates 3 can be firmly fixed on the helmet body 1, or can be part of the helmet body 1, in other words the mounting plates 3 and the helmet body 1 can be formed in one piece, furthermore the connection between these two parts can be achieved by screw, rivet, welding, buckle plug or other fixation means known in the art
  • the mounting plates 3 can adopt an integral design or a split type design, while adopting a split type design, the mounting plates 3 comprises several parts, as shown by Fig.
  • the mounted patter 3 therein consists of an outer plate 3a, inner plate 3b and bottom plate 3c, wherein the track 41 is formed by the grooves respectively on the outer, and inner plates 3a, 3b; it should be further noted that, each of the tracks 41, 42 comprises two track sidewalls A, and the portions of the outer surface of the mounting pattern 3, which are close to and spreads along the tracks 41, 42, are called track plane B, as shown by Fig.
  • the sections of the track plane B and two track sidewalls A are allowed to be connected through curve or radius transition
  • the best configuration of the two track sidewalls A of a track is that the two track sidewalls A are both perpendicular to the median plane S, and are the isometric surface of one another, of course, other arrangements for the track sidewalls A are possible as well
  • the median plane S described herein is such a plane: as shown by Fig.
  • the median plane S is a symmetry plane of the helmet through the back and top of the head, the nose and the mouth of the driver; in addition, there exists two intersection lines L1 for the two track sidewalls A of the same track or the extension planes thereof, and the outer surface of the mounting plate 3 or the extension plane thereof, and there also exists a median line on the outer surface of the mounting plate or the extension plane thereof, corresponding to the two intersection lines, the media line is called trajectory C, as shown in Fig.
  • the intersection lines L1 and the trajectory C satisfy the following rules: through a point at the trajectory C only one sphere can be made tangent to the two intersection lines L1 simultaneously, and thus the distance between these two tangent points is the width of the track 41 or 42 at this point; the trajectory C represents the motion trajectory of the moving nails 5, or in other words the trajectory C represents the motion trajectory of the moving nails 5 constrained by the tracks 41, 42; at last, the moving nails 5 may be bolts, studs, pins or two-head rivets which have a variety of transverse sections, but the optimum transverse sections include circular, elliptical, rectangular or polygonal shapes, when the moving nails 5 with a rectangular or polygonal transverse section are adopted, the edges of these moving nails 5 are required to be chamfered; it should be noted that in the present invention the moving nails 5 may be fixedly or moveably connected with the chin-guard 2, but it had better to keep the relative positions of the axis 05 of the moving nails 5 constant to the chin-
  • the two moving nails 5 in the same assembly are respectively constrained by the two tracks 41, 42 on the same mounting plate 3, as these two moving nails 5 are also connected to the same holder 2a, noted that the mounting plate 3 and the helmet body 1 are firmly fixed with each other, or formed in one piece, in each assembly, when raising the chin-guard 2, the holder 2a drives the two moving nails 5 on it to move along the tracks 41, 42 on the corresponding mounting plate 3, conversely, when pulling down the chin-guard 2, the holder 2a drives the two moving nails 5 on it again to move back along the tracks 41, 42 on the corresponding mounting plate 3, it is not difficult to find that, the tracks 41, 42 on the mounting plates constrain the motion of the moving nails, and so as to constrain the motion trajectory of the chin-guard 2 ultimately, in other words the present invention realizes the function of changing the relative position of the chin-guard 2 to the helmet body 1 according to need, namely realizing the shift between full face and open face structures, as well as allowing the chin-guard 2
  • FIG. 3 gives a status view of the process of the helmet being shifted from full face mode to open face mode
  • Fig. 4 shows the position changes of the moving nails in the tracks 41, 42 for the chin-guard 2 shown in Fig .3 , wherein Fig. 3 (a) and Fig. 4 (a) show the helmet in full face mode, wherein the chin-guard 2 is in a protective position, Fig. 3 (b) and Fig. 4 (b) show the helmet of which chin-guard 2 is just raised, wherein the chin-guard 2 is starting to climb, Fig. 3 (c) , Fig. 4 (c) , Fig. 3 (d) , and Fig.
  • FIG. 4 (d) show a crossing status, wherein the chin-guard 2 is crossing the goggle 6 and facemask 7, Fig. 3 (e) and Fig. 4 (e) show the helmet in open face mode, wherein the chin-guard 2 clings to the upper rear portion of helmet body 1.
  • the tracks 41, 42 on the two mounting plates 3 may be arranged symmetrically or asymmetrically, but the symmetrical arrangement may be better as the with this arrangement the structure of the helmet is simpler and the motion of the chin-guard is steadier; it should be noted that the symmetrical arrangement of the tracks 41, 42 of the two mounting plates 3 in relation to the median plane S could be described as: when perpendicularly projecting the trajectories C of the tracks 41, 42 of each mounting plate 3 onto the median plane S of the helmet at the same time, the projections of the trajectories C of the corresponding tracks are completely overlapped or one trajectory C is contained by the other one, more particularly, the projections of the trajectories C of the tracks 41 of the two mounting plates 3 on the median plane S are fully overlapped, or one trajectory projection is fully contained by the other one, at the same time the projections of the tracks 42 of the mounting plates on the median S are fully overlapped as well, or one trajectory projection is fully contained by the other one, the so-called "contained"
  • the tracks 41, 42 are configured to have two ultimate positions for each, including starting positions 41 a, 42a and ending positions 41b, 42b
  • a preferred embodiment can be: in the two moving nails connected with the same holder 2a, while the one cooperating with the track 41 is in the starting position 41 a, the other one cooperating with the track 42 should be in the starting position 42a as well, and while the one cooperating with the track 41 is in the ending position 41 b, the other one cooperating with the track 42 should be in the ending position 42b as well, vice versa;
  • the position of the chin-guard 2 in full face mode can be determined correspondingly while the moving nails 5 are in the starting positions 41 a, 42a, and in like manner
  • the position of the chin-guard 2 in open face mode can be determined correspondingly while the moving nails 5 are in the ending positions 41b, 42b, in order to allow the chin-guard 2 in the two ultimate positions (the full face position and the open face position) to cling to the helmet body 1, some portions
  • the holders 2a are pulled down by the moving nails to cling to the surfaces of the mounting plates 3, namely this structure is able to allow the chin-guard 2 to cling to the helmet body 1 more tightly, it should be noted that the starting positions 41 a, 42a may be overlapped or not, as shown by Fig. 8 .
  • the starting position 41 a and ending position 41 b of the track 41 may be partially or fully overlapped, of course the ending position 41 b and starting position 41 a may not be overlapped at all, Fig. 10 shows an embodiment in which the starting and ending positions are fully overlapped, while Fig. 15 shows an embodiment in which the ending and starting positions are not overlapped at all; obviously, while the starting and ending positions are fully overlapped, the trajectory C of the track 41 is a closed loop track, and the trajectory C of the track 42 must be an open loop track, thus the trajectory C of the track 41 has a point of intersection p, a preferred point P can be determined as: as shown by Fig.
  • the two track sidewalls A forming a same track may be parallel or equidistant from each other, or not parallel or not equidistant, in fact while the moving nails 5 are moving along the tracks 41, 42, in order to enhance the motion stability of the moving nails 5, the track sidewalls A on some portions of the track 41, 42 may be configured in a tapered shape, namely the track sidewalls A of at least one portion of the tracks 41, 42 form a gradually shrinking or/and expanding track width, as when the two moving nails 5 move on the tracks 41, 42 of the same mounting plate 3 to a position in which the motion directions of the two moving nails are approximately opposite, for example, while the chin-guard 2 moves to the middle of the crossing track and the adjacent area, if the radiuses of curvature of the tracks 41, 42 at that point are close in design, impacted by the force of the chin-guard 2, the motion directions of the moving nails 5 at that point may be suddenly changed easily, namely the motion of the moving nails becomes unstable, in
  • the width of track 42 is gradually increasing, on the path from W42 to V42 the width of the track 42 is gradually decreasing, on the path from U41 to W41, the width of track 41 is gradually increasing, and on the path from W41 to V41, the width of track 41 is gradually decreasing, there is no doubt that the track layout described above allows the moving nails 5 to quickly slide to the points W41 and W42, and pass through these points under the inertia effect, whatever the chin-guard 2 is shifted from the full face position to the open face position or shifted from the open face position to the full face position, the above effect can be achieved when the chin-guard 2 passes through the points W41 and W42, namely the chin-guard 2 of the present invention has greater stability; it should be noted that the shrinking width and expanding width may be applied on the track 41 or/and track 42, the shrinking width or expanding width may be a single formation, or consist of a variety of formations.
  • the mounting plates 3 are provided with shrinkable grooves 12, arranged on the both or single side thereof, and used to allow the moving nails 5 to travel more smoothly and stably, wherein the width of a portion of the tracks 41, 42 may be slightly smaller than the diameter of the portion of the journal of the moving nails 5 in the track, namely the moving nails 5 and the portion of the tracks 41, 42 have an interference fit, thus the moving nails 5 must prop open the two track sidewalls A of each of the tracks 41, 42 by force to pass through;
  • the mounting plates 3 per se can be made of elastic materials, namely even without the structure of shrinkable groove, the tracks 41, 41 can also have an interference fit with the moving nails 5, of course the elasticity of the tracks 41, 42 can be greater with the structure of shrinkable groove, accordingly the greater interference can be used to improve the motion stability of the moving nails 5 for the tracks with a shrinking or/and expanding width structure.
  • the moving nails can have a stepped journal structure, the so-called stepped journal structure is to have different transverse sections with jump changes in size at different positions along the axis 05 of the moving nails 5, for example, if the main body of the moving nail 5 is a cylinder, the moving nail 5 has at least two different shaft sections in diameter with a stepped journal structure, obviously, the adoption of the stepped journal structure can separate the chin-guard 2 and the holders 2a from the mounting plates 3 and the helmet body 1 by an appropriate distance, this could prevent the interference between the chin-guard 2 and the helmet body 1 ( and the mounting plates 3) from happening while the chin-guard 2 travels in relation to the helmet body 1, as well as reduce the contact area between the chin-guard 2 and the mounting plates 3, so as to reduce drag, Fig.
