BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates to a motorcycle helmet, and more specifically to a
motorcycle helmet wherein a shield, visor and jaw guard are configured so as to be
rotated with one hinge point to make it easy to assemble and use, while the operation
and structure of the visor are modularized into one to reduce cost and improve productivity.
2. Description of the Related Art
[0002] Motorcycle riders must wear a safety helmet to protect the head and the front of
helmet should have a shield installed to prevent sight obstruction and breathing difficulty
due to winds blowing from front.
[0003] And to protect the jaw of the wearer, a jaw guard is provided at the bottom of the
helmet in the jaw portion. Both ends of this jaw guard are pivotably mounted on hinge
portions installed on both left and right sides of the helmet body, so as to be adjusted
suitably according to the shape of the face of the wearer.
[0004] Also, a visor can be provided to intercept sunlight coming directly into the eye
in daytime. Such a visor is also pivotably mounted on the hinge portions installed
on both left and right sides for use by moving up or down as necessary.
[0005] As described above, the conventional helmet has components that need to be opened
or closed as necessary, such as the jaw guard, shield and visor, but conventionally
there were no helmets in which these three components can be opened and closed around
one shaft.
[0006] In the visor of the conventional helmet, the visor portion that can be opened or
closed, the pivot for opening and closing this visor, and the operating lever are
configured individually as separate parts and they are in such a structure that makes
it very difficult to assemble these together with the shield and jaw guard, so it
is not suitable for mass production.
SUMMARY OF THE INVENTION
[0007] Accordingly, it is an object of the present invention to provide a motorcycle helmet
having a jaw guard, shield and visor, all of which can be pivoted around one pivot
shaft.
[0008] Another object of the present invention is to provide a motorcycle helmet wherein
all the modules can be easily assembled in one place after the modularized visor parts
of an opening and closing structure are produced separately in another production
place.
[0009] In accordance with the present invention, there is provided a motorcycle helmet comprising:
a helmet body in which an opening for the face is provided on front and pivot holes
are formed on both left and right sides; a jaw guard which protects the jaw of the
wearer by covering part of the opening of the helmet body and which can be pivotably
moved by hinge portions provided on the extending portions of both left and right
sides as a hinge point; a shield which opens and closes the remaining part of the
opening above the jaw guard and which can be pivotably moved by latch pivot portions
provided on extending portions on both left and right sides as a hinge point; a visor
which intercepts sunlight incoming into part of the opening in the helmet body and
which can be pivotably moved by the lever mechanisms on both left and right sides
having control levers as a hinge point; and a fastening screw which is screwed to
pivot holes on both left and right sides of the helmet body so as to pivotably move
all of the hinge portion of the jaw guard, the latch pivot portion of the shield,
and the lever mechanisms of the visor by making pivot holes as a hinge point.
[0010] Preferably, the visor is modularized by comprising a visor body including a visor
portion for intercepting sunlight incoming into part of the opening in the helmet
body, and extending portions extended to left and right from the visor portions and
having visor pivot holes and lever inserting holes formed at the position eccentric
with the visor pivot hole; a control lever including a protuberance at one end thereof
which is inserted into the lever inserting hole of the visor body, and a lever pivot
hole at the other end thereof; a lever arm which is inserted into the lever pivot
hole of the control lever; a fastening plate which has a visor pivot inserted into
the visor pivot hole of the visor body and a lever pivot inserted into the lever pivot
hole of the control lever, and which can fix these on the inside of the helmet body;
a guide flap which is fixed at one end of the lever arm of the control lever to be
introduced within a predetermined range of movement according to the rotation of the
lever arm; and an adjusting knob which is joined to the lever arm of the control lever
by passing through the guide flap and moves within a predetermined range along an
arc hole formed on the side of the helmet body.

DETAILED DESCRIPTION OF THE INVENTION
[0012] Below will be described in more detail a motorcycle helmet according to the present
invention with reference to the accompanying drawings.
[0013] Fig. 1 is a perspective view showing a helmet according to the present invention,
and Fig. 2 is an exploded perspective view showing the helmet according to the present
invention.
[0014] As shown in these drawings, the helmet according to the present invention includes
a jaw guard 20 for covering the opening 11 in a helmet body 10, a shield 30 and a
visor 40. These parts are provided all on one pivot shaft for each to operate pivotably.
[0015] For this, on both left and right sides of the helmet body 10 are formed pivot holes
12.
[0016] And, the jaw guard 20 for protecting the jaw of the wearer by covering part of the
opening 11 of the helmet body 10 is pivotably mounted on the helmet body 10 by hinge
portions 22 arranged on both sides of the extending portions 21 of the jaw guard 20.
[0017] And, the shield 30 that can close or open the remaining part of the opening 11 above
the jaw guard 20 is mounted pivotably on the helmet body 10 by latch pivot portions
32 formed on both ends of the extending portions 31 of the shield 30.
[0018] The visor 40 that is arranged over the top of the opening 11 in the helmet body 10
to intercept sunlight is pivotably mounted on the helmet body 10 by lever mechanisms
42 installed at both ends of the visor 40. The lever mechanism 42 includes a control
lever 42a for adjusting the angle of the visor 40.
[0019] To assemble, as shown in Fig. 3, the hinge portion 22 of the jaw guard 20, the latch
pivot portion 32 of the shield 30 and the lever mechanism 42 of the visor 40 are pivotably
mounted on both left and right sides of the helmet body 10 all by a fastening screw
50. The fastening screw 50 passes through the hinge portions 22 and the latch pivot
portion 32 in sequence to be inserted into the pivot holes 12 formed on the left and
right sides of the helmet body 10 before it is screwed to a fastening plate 43.
[0020] At this time, the jaw guard 20 and the shield 30, as shown in Fig. 3, are pivotably
mounted on the helmet body 10 by the fastening screw 50 through a mounting plate 23.
Also, a spacer 24 is sandwiched between the mounting plate 23 and the fastening screw
50.
[0021] As shown in Fig. 2 and Fig. 4, a hinge hole 23a, into which the fastening screw 50
is inserted, is formed in the hinge portion 22 of the jaw guard 20 corresponding to
the pivot hole 12, and a through hole 23b corresponding to the hinge hole 23a is formed
in the mounting plate 23, so that the fastening screw 50 passes through these hinge
holes 23a, through holes 23b and the pivot holes 12 of the helmet body 10 in sequence
to be screwed to the fastening plate 43.
[0022] The mounting plate 23 is provided with a guide lip 23c and the spacer 24 is provided
with a concave-convex portion 24a corresponding to the guide lip23c so as to make
it possible to fix the jaw guard 20 in a desired position. This is roughly similar
to the structure of a conventional motorcycle helmet, so detailed description of this
is omitted.
[0023] Also, in order to adjust and fix the height of the shield 30 at a desired position,
as shown in Figs. 2 to 5, an arc slot 34 having a latch 33 is formed in the latch
pivot portion 32 and a latch protuberance 23d having elasticity is formed in the mounting
plate 23. Therefore, it is possible to fix the shield 30 by adjusting the height to
a desired position by rotating around the pivot hole 12 by the latch 33 of the latch
pivot portion 32 and the latch protuberance 23d of the mounting plate 23.
[0024] Meanwhile, the visor 40, as shown in Fig. 2, 6 and 7, has a structure entirely different
from the conventional one.
[0025] Namely, the visor 40 is modularized with a visor body 41, the control lever 42a,
the fastening plate 43, a guide flap 42f and an adjusting knob 42 so as to have a
structural characteristic for improving the productivity and assemblability of parts.
[0026] The visor body 41 comprises a visor portion 41a for intercepting part of the opening
11 in the helmet body 10, and extending portions 41d extended to the left and right
from the visor portion 41a. In the extending portion 41d of the visor body 41 are
formed a visor pivot hole 41b into which the visor pivot 43b of the fastening plate
43 is inserted and a lever inserting hole 41c for connecting the control lever 42a.
[0027] And, the control lever 42a includes a protuberance 42b at one end thereof which is
inserted into the lever inserting hole 41c of the visor body 41, and a lever pivot
hole 42c at the other end thereof. A lever arm 42d is inserted into the lever pivot
hole 42c of the control lever 42a.
[0028] The fastening plate 43 has a visor pivot 43b which is inserted into the visor pivot
hole 41b of the visor body 41, and a lever pivot 43a which is inserted into the lever
pivot hole 42c of the control lever 42a, and which can fix these on the inside of
the helmet body 10.
[0029] Also, as shown in Fig. 6, the control lever 42a has a guide flap 42f which is fixed
at the end of the lever arm 42d. When the end of the lever arm 42 pivots, this guide
flap 42f allows it be introduced along a predetermined range of motion. And, at the
end of the lever arm 42d is joined the adjusting knob 42e after passing through the
guide flap 42f. This adjusting knob 42e rotates the lever arm 42d, when the height
of the visor 40 is to be adjusted using the control lever 42a. The lever arm 42d can
be moved by the adjusting knob 42e within a predetermined range along an arch hole
13 formed on the side of the helmet body 10.
[0030] And, on the inside of the arc hole 13 are formed a plurality of catch slots 13a in
which the protruded portion of the adjusting knob 42e is inserted. Therefore, as shown
in Fig. 6, it is possible to fix the visor 40 in a desired ascent or descent position
by matching the adjusting knob 42e with any one of these catch slots 13a.
[0031] Accordingly, when the helmet wearer holds the adjusting knob 42e and moves along
the arc hole 13, the lever arm 42d moves pivotably in the lever pivot hole 42c as
a hinge point. Since the visor body 41 is moved up or down with the visor pivot hole
41b as a hinge point according as the control lever 42a is moved, the visor 40 can
be accurately moved into the position of the wearer's field of vision.
[0032] Because the protruded portion of the adjusting knob 42e is inserted in the catch
slot 13a in a state operated like this, it is possible to maintain the moved position
as it is, even after the adjusting knob 42e is moved to a desired position.
[0033] As described above, it is possible to enhance productivity by reducing cost and assembly
time by reducing the related parts, because the present invention has made the jaw
guard, shield and visor move pivotably centering on one hinge point. Also, since the
wearer is provided with all of the jaw guard, shield and visor, he can use each element
easily when necessary.
[0034] Furthermore, because it was made possible to produce the visor separately in another
production place by modularizing the parts of its opening and closing structure, the
productivity and assemblability for all the modules are improved.
[0035] Although the present invention has been described in connection with the exemplary
embodiments illustrated in the drawings, it is only illustrative. It will be understood
by those skilled in the art that various modifications and equivalents can be made
to the present invention. Therefore, the true technical scope of the present invention
should be defined by the appended claims.
