REAR VISION HELMET VISOR STRUCTURE
BACKGROUND OF THE INVENTION
(1) FIELD OF THE INVENTION
The invention relates to a rear vision helmet visor structure.
(2) DESCRIPTION OF THE PRIOR ART
Referring to FIG. 13, Taiwan patent application number 096113400, entitled
"REAR VISION STRUCTURE OF HELMET VISOR" and filed by the present
inventor, discloses an example including a visor 1 and three mirrors. The
visor
has a visor frame 6. The mirrors include a first mirror 2 disposed on a rear
portion
of the visor, a second mirror 3 disposed on a front portion of the visor, and
a third
mirror 4 disposed on the visor frame 6. Thus, the first mirror can reflect a
rear
image onto the third mirror, and the third mirror further reflects the image
onto the
second mirror. Then, the second mirror reflects the image onto the user's eyes
so
that the visor has the function of rear vision, wherein the user sees the rear
non-inverted image.
Also, another example may include one visor and two mirrors. The two
mirrors include a first mirror disposed on the rear portion of the visor, and
a
1
CA 02635831 2008-06-25
second mirror disposed on the front portion of the visor. Therefore, the first
mirror
can reflect the rear image onto the second mirror, and then the second mirror
further reflects the image onto the user's eyes so that the visor has the
function of
rear vision, wherein the user sees the rear inverted image.
Referring to FIG. 14, Taiwan patent application number 096116346, entitled
"REAR VISION STRUCTURE OF HELMET VISOR" and filed by the present
inventor, discloses an example including a visor 1 and three mirrors. The
three
mirrors include a first mirror 2 disposed on the rear portion of the visor, a
second
mirror 3 disposed on the front portion of the visor, and a third mirror 4
disposed on
the portion of the visor between the first mirror and the second mirror.
Therefore,
the first mirror can reflect the rear image onto the third mirror, the third
mirror
further reflects the image onto the second mirror, and then the second mirror
reflects the image onto the user's eyes so that the visor has the function of
rear
vision, wherein the user sees the rear non-inverted image.
The above-mentioned prior art structures have the following drawbacks.
First, because the mirror (first mirror 2) must be slightly higher than the
helmet shell in order to reflect the rear image onto the user's eyes in a
forward direction, the rear portion of the visor for fixing the mirror also
has to
2
CA 02635831 2008-06-25
be slightly higher than the helmet shell. Thus, the overall volume of the
helmet is enlarged.
Second, although the mirrors can reflect the rear image to the user's
eyes in the forward direction, they also reflect the strong vehicle lamp
source of the rear vehicle to the user's eyes. Thus, the user's eyes feel
unconformable to influence the travelling safety. So, the mirrors have to be
closed according to the user's requirement.
Third, the mirrors can make the user continuously see the image of the
rear view rolling backward. Thus, the mirrors have to be closed according
to the user's requirement when the user does not want to see the image.
SUMMARY OF THE INVENTION
It is therefore an object of the invention to provide a rear vision helmet
visor structure capable of solving the prior art problems.
The invention mainly divides a visor into a main portion and a
sub-portion, and an opening-closing structure is formed between the main
portion and the sub-portion. Mirrors may be respectively disposed on the
main portion and the sub-portion, and may also be disposed on only the
sub-portion. Thus, when the main portion of the visor is fixed to a helmet
3
CA 02635831 2008-06-25
shell, the sub-portion may be opened and closed relative to the helmet shell
so that the mirrors may be opened and closed and the volume can be
reduced.
The invention has the following advantages.
First, additional functions of the visor may be provided according to the
improvement of the helmet visor so that the helmet visor has two functions.
Second, the volume of the visor can be reduced so that the volume of
the helmet may be reduced and the prior art problems may be solved.
Third, the mirrors may be opened and closed to prevent the strong
lamp source of the following vehicle from being reflected to the user's eyes
at night.
Fourth, the mirrors may be freely opened and closed according to the
user's requirement or other conditions.
Fifth, the angles of reflection of the mirrors are adjustable.
Further aspects, objects, and desirable features of the invention will be
better understood from the detailed description and drawings that follow in
which various embodiments of the disclosed invention are illustrated by way
of examples.
