Definitions

  • pivoting fastening mechanism for helmet face shield relates to a pivoting fastening mechanism, of the type used to fix the face shield or visor of a helmet, for example a motorcycle helmet, to the body thereof, enabling said face shield to be moved, rotating on said mechanism, upwards and downwards to be able to place it in various positions from a higher position of maximum opening to a lower closing position, the mechanism exhibiting a system for releasing and repositioning said face shield that is very easy to operate, simply by pressing a button and without the need to use tools.
  • the invention also relates to a helmet and a helmet face shield.
  • the field of application of the present invention falls within the sector of the industry dedicated to the manufacture of protective helmets, particularly focussing on the field of fixing mechanisms between the face shield and the helmet.
  • the objective of the present invention is, therefore, to provide a mechanism for fixing the face shield to the helmet which, by being one of those that does not require the use of tools and of those that are operated by pressing an external button, is even easier to use, avoiding the need to perform additional motions when pressing said button.
  • the object of the present invention is a pivoting fastening mechanism for a helmet face shield according to claim 1 .
  • a fastening mechanism of the type used to fix, on both sides of the same, the face shield or visor of a helmet, for example a motorcycle helmet, to the body thereof covering the front opening, and that has a pivoting motion to enable said face shield to be moved, rotating on said mechanism, upwards and downwards to be able to place it in various positions, from a higher position of maximum opening to a lower closing position, this mechanism exhibiting the particularity of having a system for releasing and repositioning said face shield that is very easy to operate, simply by pressing a button, and without the need to use tools.
  • the mechanism of the invention to disassemble the face shield, it is only necessary to position it in the open position thereof, that is, the higher one, and, applying a slight outward pressure on the internal portion of the face shield, for example, simply positioning the finger between the face shield and the helmet, the button of the mechanism is pressed and it sinks, resulting in the release of the face shield simply by pulling it out, without having to perform any other motion.
  • the mechanism is extremely easy to use since it will be sufficient to place it back on the helmet, so that both portions of the mechanism are facing each other, and press to lock it in place again, without it being even necessary in this case to have to press the button again or carry out any previous or subsequent motion.
  • the mechanism that the invention proposes comprises two portions that can be coupled to each other: a first fixed portion, which is incorporated into the helmet, and a second pivoting portion that is incorporated into the face shield.
  • a first fixed portion which is incorporated into the helmet
  • a second pivoting portion that is incorporated into the face shield.
  • the first portion of the mechanism that is incorporated into the helmet, hereinafter the fixed portion, comprises, in turn, several elements coupled to each other to receive and lock the second portion or pivoting portion of the face shield with the possibility of rotation with respect to the first one and which, in turn, is also made up of several elements coupled to each other.
  • the fixed portion of the mechanism basically comprises a lower support plate that is fixed to the surface of the helmet, preferably by means of a screw, and a circular upper base, respective locking sliding elements being between said plate and said base, opposed and symmetrical which, pushed by respective springs, tend to approach and position themselves partially occupying the central gap of the upper base.
  • the portion of the mechanism that is incorporated into the face shield hereinafter the pivoting portion, comprises a protruding structure or protrusion that emerges from the inside portion of the face shield, that is, on the side of the face shield that faces the helmet, which is preferably mushroom-shaped, with a bevelled inner surface, and a perimeter groove in what would be the trunk of said mushroom-shaped protrusion, being dimensioned to fit snugly in the central gap of the upper base of the fixed portion of the mechanism.
  • said same protrusion exhibits a circular housing wherein it incorporates a button, associated with a spring that tends to keep it in a high position, which, when pressed, pushes two levers that emerge from the opposite side of the face shield and partially cover the aforementioned perimeter groove of the protrusion.
  • release levers are arranged on diametrically opposite sides of the button and in such a way that, when the visor is in the closed position, they do not coincide with the position of the locking sliding elements, which are also arranged at diametrically opposite points of the gap of the upper base, so that, no matter how long the button is pressed, the face shield cannot be extracted in that position. And, only when the face shield is in the open position can it be extracted, since in this position the button levers do coincide with the locking sliding elements, causing them to move if the button is pressed, thereby releasing the mushroom structure and the face shield being able to be extracted.
  • a spring has been provided with a stop that, when the face shield is lowered, pushes a lug provided for this purpose on the internal face thereof so that it is not lowered completely and is fixed in said position, in which it has been provided that there is a minimum opening between the face shield and the surface of the helmet that enables air to enter in order for it to not get fogged up.
  • an internal flap is provided in the centre of the face shield that fits into a retractable projection provided in coincidence in the centre of the opening of the helmet with which said flap is interlocked to ensure the closure of the face shield.
  • the main advantage of the mechanism of the present invention is that, in addition to not requiring the use of tools to extract and reposition the face shield on the helmet, it does not require lateral or any other type of motions of the face shield. Only by pressing the button it is already released and, to position it, it is sufficient to put both portions of the mechanism facing each other and press to make them fit. No other extra manipulation or looking for a certain angle or anything else is required. It is, therefore, an extremely simple and convenient mechanism to use.
  • the fixed portion of the mechanism is fixed to the helmet by means of a simple screw and the assembly has a reduced size.
  • Another object of the invention is a helmet with a face shield according to claim 9 that exhibits an assembly that enables the coupling of the face shield to the helmet by means of a pivoting fastening mechanism according to the preceding description.
  • Another object of the invention is a helmet face shield or visor, of the type that can be coupled and uncoupled from the same, as well as being able to be raised and lowered, according to claim 10.
  • a final object of the invention is a helmet according to claim 13.
  • Figure number 1 shows an exploded perspective view of an exemplary embodiment of the pivoting fastening mechanism for helmet face shield, object of the invention, showing the different portions and elements that it comprises, as well as the configuration of each one of them.
  • Figure number 2 shows a front elevation view of the portion of the mechanism that is fixed to the helmet, showing the elements that it comprises once they are coupled to each other.
  • Figure number 3 shows a side elevation view of the portion of the mechanism that is fixed to the face shield, showing the configuration thereof, once the elements it comprises are attached to the face shield.
  • Figures number 4 and 5 show respective front and rear perspective views of the assembly of the mechanism, once the elements of each portion and both portions have been coupled to each other, having been represented without incorporating the helmet or the face shield.
  • Figure number 6 shows a side elevation view of the assembly of the mounted mechanism shown in Figures 4 and 5.
  • Figure number 7 shows a side elevation view of a helmet with the face shield fixed by means of the mechanism of the invention, showing this from the front portion thereof.
