    [0001]
    [0002] Helmet of protection for motorcyclists.
    [0003]
    [0004] Object of the invention.
    [0005]
    [0006] The object of the invention is a protective helmet for motorists comprising a front window and lateral mechanisms for mounting the respective sides of a transparent screen with possibility of rotation between an open position and a closed position of the front window .
    [0007]
    [0008] This helmet presents some improvements oriented to facilitate the manipulation of the lateral mechanisms and to allow the disassembly of the screen using only one hand.
    [0009]
    [0010] Field of application of the invention.
    [0011]
    [0012] This invention is applicable in protection helmets for motorcyclists.
    [0013]
    [0014] State of the art
    [0015]
    [0016] Currently, the screens installed in motorcycle protection helmets allow their disassembly for cleaning or replacement.
    [0017]
    [0018] These helmets have lateral mechanisms for mounting and releasing the screen. Said mechanisms consist of a displaceable piece between an unlocking position in which it allows the dismantling of the screen and a blocking position in which it prevents disassembly of the screen and allows the screen to rotate with respect to the helmet between extreme opening positions. and close.
    [0019]
    [0020] This sliding, blocking and unlocking part of the screen moves in a lateral direction with respect to the axis of rotation of the screen and tends to be maintained permanently in the blocking position by the action of a pushing means; This determines that the said piece is manually squeezed in the unlocked position to disassemble the helmet screen.
    [0021]
    [0022] The drawback of this mechanism is that to disassemble the screen you must use both hands, one to keep the piece in the unlocked position and the other to grip and disassemble the screen.
    [0023]
    [0024] Description of the invention.
    [0025]
    [0026] The protection helmet for motorcyclists object of this invention has some characteristics related to the mounting and securing the screen with respect to the helmet.
    [0027]
    [0028] Said characteristics are oriented, on the one hand, to allow that once the displaceable piece is operated towards the unlocking and releasing position of the screen, said movable piece is kept in said open position until the screen is mounted again on the helmet, allowing that the screen can be removed with one hand; and on the other hand, a mechanism for locking the screen in the closed position is incorporated into the helmet, and when activated, unlocks the screen and causes it to turn automatically to a first opening position.
    [0029]
    [0030] The features of the invention will be more readily understood in view of the embodiment example shown in the accompanying figures that are described below.
    [0031]
    [0032] Description of the figures.
    [0033]

    [0039]
    [0040] - Figure 3 shows a mounting detail of one of the sides of the screen in one of the side mechanisms of the helmet having the screen shown in the position of maximum opening.
    [0041]
    [0042] - Figure 4 shows an enlarged detail on the lower floor of a horizontal section of one of the ends of the screen coupled with one of the side mounting mechanisms of the helmet.
    [0043]
    [0044] - Figures 5 and 6 show different views similar to Figure 4 in different phases of disassembly of the screen.
    [0045]
    [0046] - Figure 7 shows a side view of the disassembled screen of the helmet.
    [0047]
    [0048] - Figures 8 and 9 show different views analogous to figures 4, 5, 6 in different phases of screen assembly
    [0049]
    [0050] - Figure 10 shows a side view of the helmet, once the lock latch of the screen is released in the closing position and displaced said screen towards a first opening position by a pushing means arranged on the sides of the helmet.
    [0051]
    [0052] Preferred embodiment of the invention.
    [0053]
    [0054] As can be seen in figure 1, the motorcycle protection helmet comprises a shell or helmet (10) itself provided with a front window and lateral mechanisms for mounting the respective sides of a transparent screen (20), with the possibility of turning between an opening position shown in figure 3 and a closing position of the front window shown in figures 1 and 2.
    [0055]
    [0056] The lateral mechanisms for the assembly of the screen (20) in the helmet comprise a cylindrical configuration (101) engageable in a recess (201) of the corresponding end of the screen (20) and which defines an axis of rotation of the screen ( 2) between opening and closing positions.
    [0057]
    [0058] Said lateral mechanisms comprise a first curved guide (102) suitable for reception in the radial direction and the circumferential displacement around the axis of rotation of a first radial appendix (202) of the screen (20), and a displaceable part (103). radially, in anterior-posterior direction, between unlocking and unlocking positions of the screen (20).
    [0059]
    [0060] Said displaceable piece (103) comprises a second curved guide (104) for the reception in the radial direction and the circumferential displacement of a second radial appendix (203) of the screen (20) in the mounting position of the screen (20) with respect to to the hull (10).
    [0061]
    [0062] According to the invention, the lateral mechanisms for mounting the screen comprise a flexible tab (105) which tends to be maintained, by the elasticity of the material forming same thereof, in an operative retention position of the displaceable part (103) in the unlocking position of the screen (20), shown in figures 5, 6 and 7.
    [0063]
    [0064] Starting from the assembly position shown in figures 3 and 4, the disassembly of the screen (20) can be done with one hand, as shown in figures 5 and 6, since once the displaceable piece is located ( 103) in the unlocking position of the screen (20), said displaceable piece (103) is retained in said unlocking position by the flexible tab (105), being able to initially perform the release of the second radial appendix (203) of the second curved guide (104) and then the release of the first radial appendage (202) of the first curved guide (102).
    [0065] As can be seen in figures 8 and 9, during the assembly of the screen (20) the flexible tab (105) is displaced by the screen (20) itself to an inoperative position, in which it is introduced below the displaceable piece (103), releasing said displaceable piece (103) and allowing its automatic return to the blocking position of the screen (20).
    [0066]
    [0067] The lateral mechanisms for mounting the screen comprise springs (106) that are compressed when the displaceable part (103) moves towards the unlocking position of the screen (20) and that return it to the blocking position when the tab flexible (105) is moved to the inoperative position.
    [0068]
    [0069] The lateral mechanisms for mounting the screen (20) comprise means for retaining the screen in successive positions of progressive opening between a closing position shown in figures 1 and 2 and a maximum opening position shown in figure 3. Said retaining means comprise a corrugated profile piece (107) against which a teton (204) of the screen (20) acts laterally, said wavy profile (107) determining the different opening positions of the screen (20).
    [0070]
    [0071] As can be seen in figures 2 and 10, the helmet comprises in the frontal area a locking latch (108) of the screen in the closing position and in the sides elastic means (109) for pushing the screen towards a position opening.
    [0072]
    [0073] In figures 1 and 2 the screen (20) is retained in the closing position by the locking latch (108) and in said closing position the elastic means (109) are kept compressed by the screen (20) itself. In the example shown the screen (20) acts against the elastic means (109) by means of a stop (205) defined therein.
    [0074]
    [0075] As shown in Figure 10 when releasing the lock latch (108) from the screen (20) in the closing position, said elastic means (109) act against the screen, more specifically against the stop (205) of the screen, causing rotation of the screen (20) from the closing position shown in figures 1 and 2 towards a first opening position shown in figure 10.
    [0076] In the example shown, the cylindrical configuration (101) engageable in the recess (201) of the corresponding end of the screen (20) is defined in a piece mounted on the helmet (10) and that can move slightly in the same direction as the piece. displaceable (103), tending to stay distanced from said displaceable piece by the action of a spring (110).
    [0077]
    [0078] Once the nature of the invention has been sufficiently described, as well as an example of a preferred embodiment, it is stated for the appropriate purposes that the materials, form, size and disposition of the described elements could be modified, provided that this does not imply a alteration of the essential features of the invention that are claimed below.
