Abstract

HELMET HEADBAND FOLDABLE AFTER USE AND CARRYING AN EARPHONE AT EACH END. THE ENTIRE OR AT LEAST A SIGNIFICANT PART OF THE HEADBAND IS CONSTITUTED BY CURVED LAMELLAR ELEMENTS 1, 2, 1, 2 FORMING AN EXTENSIBLE CLAMP. THE INVENTION REDUCES THE OVERALL CONSTRUCTION OF HELMETS, IN PARTICULAR FOR THEIR STORAGE OR STORAGE.

Description

The present invention relates to a collapsible helmet headband

  after use and wearing a headphone at each end.

  Various solutions are known to reduce the bulk of

  helmets, in particular for their storage or storage.

  to divide the headband of the helmet into individual pieces,

  connected and mobile in relation to each other, and which are

  and / or unfolded at the time of use to form a greenhouse

  These designs have the following disadvantage: due to the stability of the headband required in use, the connected and moving parts of the folding or sliding headband must not be too small, so that the folded headband or closed remains unmanageable, and does not present a shape allowing for

  example to carry it easily in a pocket of clothing.

  The invention relates to a helmet headband does not have the disadvantages of known models, sufficiently flat and manageable in the folded state to allow easy storage of the helmet that team in small containers, such as pockets of garment, and therefore also having a small footprint for storage and / or storage, while having in position of use a stability

  equal to that of a helmet headband in one piece.

  The headband according to the invention must also be simple and less

  as expensive as that of known models, generally complex.

  According to an essential characteristic of the invention, all or at least a large part of the headband consists of

  bent lamellar elements forming an extensible clamp.

  The embodiment of the headband in the form of an extensible clamp has the advantage of allowing the use of identical parts, extremely simple As a result of the given radius of curvature of the lamellae of the clamp and given the absence ju practice in the joints of the forceps, the lamellae undergo, in the middle of

  their displacement, a twist that tends to make the abrupt clip

  This results in a total absence of stress on the clamp, both in the folded position and in the position of use, so that a helmet equipped with a

  headband according to the invention is not likely to lose its form of use.

  For example, in the case of a construction as simple as that of an extensible clamp, practically only using slats made of sheet metal and / or plastic and conventional or hollow rivets, the production costs are extremely low and lower than those

  foldable and / or sliding headband, offering at least

  the same comfort of use -

  According to another characteristic of the invention, the slats are made of elastic materials. This solution is advantageous because the slats resting on the head, for example, can be made of plastic, producing in bald users a more pleasant sensation than slats in eg steel To transmit the acoustic frequency currents to a

  the earpiece by the headband, and according to another advantageous feature

  of the invention, hollow rivets are used, which allow the passage of a cable This solution has the advantage of a guide

  precise cable, which no longer hangs freely According to another characteristic

  Advantageous of the invention, the cable headband comprises a locking screw, which can be arranged at a point of articulation

  any of the extensible clamp The safety of maintaining the posi-

  tion chosen is further increased as well.

  According to another characteristic of the invention, the headband comprises at the two ends of the short lamellae, half the length of the other lamellae. Thus, protruding lamella parts are avoided at the ends of the headband. The hollow rivets connecting the lamellae short ends at the ends of the headband can advantageously

  serve for the articulated fixation of the earphones.

  Other features and advantages of the invention will be better

  understood using the detailed description below of an example

  embodiment and the appended drawing in which:

  FIG. 1 is the plan of a helmet equipped with the headband according to the invention.

  in the folded position; Figure 2 is the side elevation of the casqiuea according to Figure 1; and FIG. 3 is the perspective view of a helmet equipped with the headband

  according to the invention, in the position of use -

  The extensible clamp constituting the headband of the helmet is shown in the folded position in FIG.

  lamellae 1 and 2, the lamellae located on the outside in

  are designated by 1 and those within

  In the position of use of the helmet, the slats 2 rest on the head of the user and may be of plastic material, as previously indicated. The ends of the slats 1 and 2 inside the clamp are hingedly connected by hollow rivets 3, and also include a hollow rivet 4 at their point of intersection, in the middle of each lamella The hollow rivets located at the ends of the extendable clip are designated by 5-and fix

  the headphones 6 with the headset 7, as shown in Figure 2.

  However, it is also possible to have an articulation of

  any connection between the hollow rivets 5 and the earphones 6.

  Figure 2, which is a side elevation of a folded helmet,

  equipped with a headband according to the invention, shows the necessary curvature

  different slats of the extensible forceps, in order to obtain

  a bent headband in the position of maximum extension

  of the various slats 1, 2 is chosen so as to obtain a

  spacing of the ends of the headband in the lower position of use

  at the distance normally given between the two ears of the user, to ensure elastic application earphones on the ears Figure 2 further illustrates the presence of a locking screw 9, which can be provided at a point any articulation of the extensible clamp A locking screw is sufficient, since all the lamellae 1, 2 are coupled and the immobilization of a

  only hinge thus completely fixes the clamp.

  Figure 3 shows a helmet according to the invention in perspective.

  It shows that the ends of the headband each comprise two short strips 1 'and 2', connected by a hollow rivet 5 at each end of the clip In the conventional embodiment of the expandable clip, the end strips are not shortened but are used to operate the clamp and usually have rings identical to those of normal clamps Extenible clamps are known in the industry, for example for certain types of pipe cutters, fixtures and toys They are not

  not used until now in the mechanical part of acoustics

  that, in particular for helmets and even less with

  bent individual members as in the invention Figure 3 shows

  in addition, a cable 8, connected to an earphone of the helmet at one end,

  mite of the clamp, extends in the form of 8 'cable along the serretête, passing alternately from bottom to top and vice versa through the hollow rivets 3 and 4 It goes without saying that in a stereo headphones, the cable 8' transmits a channel to the second listener, which can

  also be equipped with its own cable 8.

  Of course, various modifications may be made by those skilled in the art to the principle and to the devices which have just been described solely by way of nonlimiting examples, without

depart from the scope of the invention.
