Definitions

  • this invention relates to a system to attach a transparent visor onto a crash helmet, of the kind which is most commonly used in motorcycling.
  • visor to cover the face.
  • the purpose of the visor is to provide protection from the wind, impact from flying insects, dust, and other external bodies.
  • the visor is generally fixed onto both sides of the helmet in such a way that it can be lowered for use, or raised when it is not required.
  • the helmet and visor design normally allows the user to position the visor at different positions between fully open and fully closed.
  • One of the problems with these helmets is the difficulty of removing the visor to clean or replace it. In many cases, this operation requires the use of tools, and dismantling other parts of the helmet, such as the chin guard, when this is also retractable.
  • the helmet incorporates side plates with cylindrical openings to insert the cylindrical pivots, which are situated on the sides of the visor. When duly out of alignment, rims fit over to allow the pivots to be introduced sideways into the openings.
  • each pivot is guided over the outer surface and into the openings in the side plates.
  • the rims in the hole and the aforementioned arm stop the visor pivots from coming loose.
  • patent JP- A- 10 110320 a "device for attaching a helmet's shield plate” is described where "the boss part formed on the side of the shield plate” is externally mounted on a turning axis that is joined to the helmet.
  • This external mounting requires the use of a supporting unit that acts against the boss part of the transparent visor and turns together with the transparent visor around the axis that is joined to the helmet. Having the supporting unit hold the transparent visor in place turns out to be complex, not very reliable, and requires a large number of moveable parts, thus increasing the manufacturing costs of the device.
  • This device which holds the transparent visor on the helmet as explained above, includes the two support plates fixed onto the sides of the helmet. There are openings in these plates, into which the pivots located on the inside sides of the visor are placed. A device inside the opening in each plate holds the pivot in place, and also allows for rotation.
  • the visor can therefore be raised or lowered by a system which is designed to simplify visor assembly, which pushes aside the springs acting on the devices holding them in place, and permits the pivots to turn in a system that holds them securely in the assembly position.
  • the visor pivot design consists of a cylindrical section with a side opening, the free end connects with a locating rim on the inside of the pivot system, with a smaller internal diameter than the cylindrical section.
  • the openings within the support plates to locate the visor pivots into the pivot system are in the form of long cylindrical slots.
  • the width of the slots is less than the diameter of the aforementioned cylindrical configuration.
  • the cylindrical arrangement of the openings in the support plates permits the visor pivots to be introduced perpendicularly, without the need to hold the visor sideways, as with previously mentioned systems.
  • the system to hold the pivots in place, and thus attach the visor to the helmet comprises sliding parts mounted between the support plates and the outer surface of the helmet.
  • These sliding parts which are located on the outer side face, near the back, have cylindrical protrusions, with an initially smaller diameter in cross-section, and end with a larger diameter.
  • these cylindrical protrusions are used to guide the sliding parts over the slots located in the support plates whilst moving between the two end positions to mount or remove the visor.
  • the outside diameters of the initial and end cross-sections of the aforementioned protrusions are the same or slightly smaller than the inside diameters of the cylindrical section and the visor pivot rims. This allows these protrusions to be inserted within them, and act as a turning axis when the visor is mounted.
  • these parts In order to hold the sliding parts in either of the two end positions, to mount or release the visor, without the need for springs or additional parts, these parts have two separate grooves on the same side in which a stub in the corresponding support plate can be located. The location of a stub in either of the grooves allows the sliding part to be held at the corresponding end position until it is manually moved to the other extreme.
  • visor Inside the visor there are some cylindrical stubs, which act against the tabs of a flexible arm fixed on the support plates. This allows the visor to be held firmly in various positions, from closed to fully open.
  • Two of the end stubs have some grooves on the side facing the flexible arm, to locate the end tabs of the arm. This permits the visor to be held open at the minimum position, which is sufficient to stop the visor from misting up on the inside.
  • the system to mount the visor (1) onto the helmet (2) incorporates two support plates (3), fixed onto the sides of the helmet (2), which contain openings (4) into which the pivots are inserted (5) for the visor (1).
  • the pivots (5) consist of a cylindrical section and a side opening (51), the free end of which has a rim (52) orientated towards the centre of the pivot, and which has a smaller inside diameter than the aforementioned cylindrical section of the pivot (5).
  • the openings (4) in the support plates (3) are cylindrical, and extent sideways to form a slot (41).
  • the visor (1) is fixed onto the support plates (3) by inserting each pivot (5) into the opening of the cylindrical system (4), such that the side opening (51) faces the side slot (41) of the opening.
  • the system To hold the visor (1) in assembly position, the system has two sliding parts (6) mounted on the support plates (3) and the outer surface of the helmet (2).
  • sliding parts (6) incorporate cylindrical protrusions (7), with an initial cross-section (71) of a smaller diameter, and an end cross-section (72) with a greater diameter.
  • the protrusions (7) are then located inside the slots (41) of the support plates (3), guiding the sliding parts (6) when they are moved between the two extremes, as shown in Figures 2 and 3, corresponding to the position for fixing or for release of the visor.
  • the sliding parts (6) have two separate grooves on one side (73 & 74), for the optional introduction of a stub (8), located on the support plate (3).
  • the introduction of this stub (8) into one of the grooves (73 or 74) prevents the sliding part (6) from moving from one of the end positions, until it is moved manually to the other extreme.
  • visor (1) Inside the visor (1) some cylindrical stubs (10) contact with the end protrusions (91) of an arm (9) on the support plate (3). This permits the visor (1) to remain open at one of the various positions, or to be securely closed.
  • Two of the cylindrical end stubs (10) have grooves (101) facing the side of the arm (9) in which the protrusions (91) can be inserted to hold the visor (1) open at the minimum position, which is sufficient to stop it from misting up on the inside.
