Description

- 1 - 2493686

  The present invention relates to a device for adjusting

  the opening of the visor of helmets for motorcyclists and the like.

  As we know, with regard to motorcycle helmets -

  you and mainly full-face helmets, a problem currently very much felt is that of the opening of the visor and especially obtaining a

  intermediate open position.

  Currently, known solutions for opening the visor in an intermediate position, offer screw means or the like which, acting by pressure on the end of the visor, block it in the

desired position.

  This achievement has not been satisfactory for motorcyclists, since it requires the use of both hands, which is

  impractical while the vehicle is running.

  To overcome these drawbacks, devices have already been introduced on the market making it possible to obtain the positioning of the visor in a

  intermediate position, using only one hand.

  These devices are currently produced in the most different forms, but are of very complicated structure, and therefore

are susceptible to jamming.

  The present invention proposes to eliminate the drawbacks mentioned above, by providing a device for adjusting the opening of the visors of helmets for motorcyclists and the like, allowing the visor to be opened in an intermediate position with one hand. only, and who

  more, either of simple structure, which allows operation without jamming

ment.

  A particular object of the present invention is to provide a device which can be mounted quickly and simply, without use

  complicated or special devices.

  Another object of the present invention is to provide a device

  tif formed of a reduced number of components cooperating with each other, guaranteeing

safe operation.

  Yet another object of the present invention is to realize

  a device easy to manufacture by the use of elements and materials available

  bles in the trade, and which are of very reduced cost.

  The above-mentioned goals are achieved through a provision

  tif for adjusting the visor opening of helmets for motorcyclists,

  characterized in that said device comprises, at each end of the vi-

  safe, a pawl housed in a disc body associated with the connection pin 39 of the visor to the helmet, and can be moved against elastic means

2 493686

  this pawl engages removable with its free end in seats of

  positioning integral with the visor.

  These features and benefits will become more apparent from the

  detailed description below of a device as mentioned above,

  and attached drawings in which: FIG. 1 represents a helmet provided with the device according to the present invention, the visor being in its closed position;

  Figure 2 shows a helmet with the visor in its posi-

opening;

  FIG. 3 represents, on an enlarged scale, a detail of the arrangement

  sitive according to the present invention; and Figure 4 is a sectional view taken along line IV-IV of

Figure 3.

  Referring to the figures, the device according to the present invention comprises at each lateral end of the visor 1, a body 2 of substantially circular shape arranged concentric with the pin 3 which connects

visor 1 to helmet 4.

  The body 2 is integral with the helmet 4 thanks to a pivot 5 extending

  from its contact face with the helmet 4 to fit into a corresponding hole

  laying. The disc body 2 is further housed so as to be able to rotate in a substantially cylindrical cavity 6, formed on the inner face of the visor 1. On the periphery of the disc body is further provided a radial cavity 7 in which is housed a pawl 8, pushed by means

  elastic formed by a helical cylindrical spring 9, acting on the end

interior mite of said pawl 8.

  This pawl in particular has at its free end a substantially hemispherical shape which engages in seats 10 spaced from one another and integral with the visor, to define stop positions of the visor, c ie closing, opening or a position

intermediate.

  The disc body 2 is provided, on a part of its periphery

  a cavity 11, in which the anterior and posterior epaulettes are housed

  laughing 12 and 13 which delimit the zone where the seats 10 are provided.

  In addition, by engaging with the ends of the cavity 11, also determine the end-of-travel positions for the rotation of the visor 1 relative to

  to the body 2, that is to say open visor and closed visor.

  The use of the device according to the present invention is very simple: The pawl 8 engaged in the first seat 10, as shown in FIG. 3, the visor is in its closed position stably when the motorcyclist wishes to open the visor, it acts on the latter so as to rotate it around the body 2 and exceed the elastic force of the helical cylindrical spring 9, which allows the retraction of the pawl 8 into the radial cavity 7, and the successive and automatic positioning of the pawl in the seats successive, that is to say in open positions

stable medials.

  The same operation must be carried out if you want the visor to be fully open, either by engaging the pawl 8

in the last seat 10.

  As can be seen, the desired opening and positioning of the visor can be obtained by exceeding the elastic force of the cylindrical helical spring 9, which allows the automatic housing of the

pawl 9 in the seat 10 chosen.

  From the preceding description, it can be noted that the present

  invention achieves the goals mentioned above and in particular that it is possible to obtain a stable and secure positioning by structural means

  simple and therefore able to operate without jamming.

  In addition, the device being formed by a very small number

  components, its assembly is very fast and very low cost.

  In practice, the materials used, the dimensions and the

  shapes can be any according to requirements.
