BACKGROUND OF THE INVENTION
[0001] The present invention relates to an improved front visor for helmets in general.
[0002] As is known, prior front visors, as typically used for motorcycle helmets and the
like, comprise a front element, which is made of a substantially rigid plastics material
defining the protective element.
[0003] The latter must be coupled to the helmet, so as to be easily removed therefrom as
required.
[0004] In prior helmet constructions, the coupling means are usually very complex and, moreover,
since the front element is substantially rigid, it can be brittle, and can be easily
broken during coupling and uncoupling operations for coupling/removing it to/from
the visor, and, moreover, it can also represent a dangerous element in the use of
the helmet proper, with the possibility of damaging the user.
SUMMARY OF THE INVENTION
[0005] Accordingly, the aim of the present invention is to overcome the above mentioned
problems, by providing an improved front visor for helmets in general which can be
easily and quickly applied to the helmet, without any risks of breaking it.
[0006] Within the scope of the above mentioned aim, a main object of the invention is to
provide such a front visor which, in addition to operating as a sun beam shading element,
is also adapted to operate as an impact protective element.
[0007] Another object of the present invention is to provide such a front visor which can
be made by a novel and improved method, allowing to greatly reduce the making cost
of the visor.
[0008] Yet another object of the present invention is to provide such a front visor which,
owing to its specifically designed constructional features, is very reliable and safe
in operation.
[0009] According to one aspect of the present invention, the above mentioned aim and objects,
as well as yet other objects, which will become more apparent hereinafter, are achieved
by an improved front visor for helmets in general, characterized in that said front
visor comprises a plastics material front element, at the rear of which is rigidly
coupled a laminar element supporting snap operating push-buttons, said front element
and laminar element being made rigid with one another through a foamed plastic material
filling.
BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Further characteristics and advantages of the present invention will become more
apparent hereinafter from the following detailed disclosure of a preferred, though
not exclusive, embodiment of an improved front visor for helmets in general, which
is illustrated, by way of an indicative, but not limitative, example, in the accompanying
drawings, where:
Figure 1 is a schematic perspective view, as partially broken away, showing the front
visor according to the present invention;
Figure 2 is a bottom plan view showing the visor according to the present invention:
Figure 3 is a rear elevation view showing the visor according to the present invention;
Figure 4 shows the mutual arrangement of the front element and laminar element of
the visor; and
Figure 5 is a cross-sectional view, substantially taken along the cross-line V-V of
figure 2.
DESCRIPTION OF THE PREFERRED EMBODIMENT
[0011] with reference to the number references of the above mentioned figures, the improved
front visor for helmets in general, according to the present invention, which has
been generally indicated by the reference number 1, comprises a front element 2 which
is advantageously made of a plastics material and, preferably, of a polycarbonate
material and by a thermoforming method.
[0012] The shape of said front element 2 can be of any desired shape, depending on the making
requirements.
[0013] At the rear of the front element 2 is rigidly coupled a laminar element 3, made of
a die-cut polyethylene material, on which are provided a plurality of snap-operating
push-button elements 4, which are made by arranging on the laminar element 3 a male
rivet 5, engaging with a female rivet 6 forming the female element of- the snap operating
push-button, whereas the male element is obviously coupled to the helmet.
[0014] A main feature of the present invention is that the laminar element 3 is made rigid
with said front element 2 by a foamed plastic material filling 10, preferably comprising
foamed polystyrene.
[0015] The latter is molded inside the thermoformed front element, thereby providing a monolithic
body between the laminar element 3 and front element 2.
[0016] with such an arrangement, the visor, in addition to being easily and quickly applied
to the helmet, also operates as a protective element, since it provides a resiliently
yieldable body, which, owing to its specifically designed features, can absorb, at
least in a partial manner, the exerted impacts.
[0017] From the above disclosure it should be apparent that the invention fully achieves
the intended aim and objects.
[0018] In particular, the fact is to be pointed out that the invention provides an improved
and novel method for making the above mentioned front visor.
[0019] In fact, the latter is constituted by a monolithic body firmly holding the snap operating
push-buttons 4 for clamping the visor to the helmet while providing a further protective
element, in addition to also provide a shield against the sun beams.
[0020] In practicing the invention, the used materials, provided that they are compatible
to the intended application, as well as the contingent size and shapes, can be any,
according to requirements.
