Technical Field
[0001] The present disclosure relates to a jaw protector opening apparatus and a helmet
having the apparatus, and more particularly, to a jaw protector opening apparatus
capable of opening a jaw protector while protecting the head of a wearer, and a helmet
having the apparatus.
Background Art
[0002] When riding a two-wheeled vehicle such as a motorcycle, a rider should wear a helmet
for protecting the head of the rider.
[0003] A shield is installed at the front of the helmet so that the range of vision of the
wearer is not disturbed by wind power generated at the front when the vehicle is running
and also a respiratory trouble may be solved.
[0004] Meanwhile, the general helmet configured as above includes a jaw protector installed
at a lower side of the front end of the helmet in order to protect the jaw of the
wearer.
[0005] Both ends of the jaw protector are fixed to both sides of a helmet body, and the
jaw protector fixed to the helmet is firmly fixed so as not to deviate from the helmet.
[0006] However, in a state of wearing the helmet, the wearer is not able to talk with other
persons, have drink or smoke. In addition, the jaw protector of such a general helmet
has buffer material provided in its outer body, and a fixed portion serving as an
axis of the center of gravity is installed at the center of the helmet body. Therefore,
when a wearer wears the helmet, the load of the jaw protector is applied to the front
side of the wearer, which greatly deteriorates the wearing sensation of the helmet.
[0007] Korean Patent Application No.
10-2003-0096273 (entitled "a helmet having an openable jaw protector) discloses a helmet having an
openable jaw protector to solve the above problem.
[0008] The jaw protector of the helmet disclosed in Korean Patent Application No.
10-2003-0096273 includes a hinge mechanism and a locking mechanism so that the jaw protector may
be opened or fixed.
[0009] However, in case of the jaw protector disclosed in Korean Patent Application No.
10-2003-0096273, the hinge mechanism and the locking mechanism for fixation to the helmet or opening
from the helmet have complicated structures and thus occupy a great space in the jaw
protector. Accordingly, the jaw protector including such components has a great size,
and thus a space required for providing a safety device such as a cushion member in
the helmet is relatively reduced.

Best Mode
[0014] Hereinafter, embodiments of the present disclosure will be described in detail with
reference to the accompanying drawings so as to be easily implemented by those having
ordinary skill in the art. However, the present disclosure can be implemented in various
ways, without being limited to the embodiments. In addition, in the drawings, features
having no relation with the disclosure are not depicted for clear explanation, and
like reference numerals denote like elements throughout the specification.
[0015] In the specification, when describing that any portion is "connected" to another
portion, this connection includes not only "direct connection" but also "electric
connection" by which both portions are connected via another element. In addition,
when describing that any element "includes" a component, this means that the element
does not exclude another component but can further include any other component.
[0016] First, referring to Figs. 1 to 3, a jaw protector opening apparatus and a helmet
having the same according to the present disclosure includes a helmet body 10, a jaw
protector 30 pivotally coupled to the helmet body 10, a release button 50 provided
at one side of the jaw protector 30, and a fixing/releasing unit 100 provided in the
jaw protector 30.
[0017] The jaw protector 30 is pivotally coupled to the helmet body 10 to protect portions
around the jaw of the wearer. The jaw protector 30 is pivotally coupled to the helmet
body 10 in order to allow a wearer to open the jaw protector 30 if necessary.
[0018] Accordingly, the release button 50 is provided at one side of the jaw protector 30,
at the center of a lower side of the jaw protector 30 in this embodiment, to release
the coupling between the jaw protector 30 and the helmet body 10 so that the jaw protector
30 may be opened.
[0019] For example, the release button 50 may release the coupling between the jaw protector
30 and the helmet body 10 by pulling, and the release button 50 may be hinged to the
jaw protector 30 to pivot by a predetermined angle when the release button 50 is pulled.
[0020] The fixing/releasing unit 100 provided in the jaw protector 30 is connected to the
release button 50 so that, when the release button 50 is pulled, the fixing/releasing
unit 100 releases the coupling between the jaw protector 30 and the helmet body 10
in association with the release button 50 to open the jaw protector 30.
[0021] The fixing/releasing unit 100 associated with the release button 50 will be described
in more detail with reference to Figs. 3 to 6. The fixing/releasing unit 100 includes
a fixed plate 110 coupled to the inner side of the jaw protector 30, a pivoting lever
130 pivotally coupled to one side of the fixed plate 110, an elastic body 150 connected
to the pivoting lever 130 to restore the location of the pivoting lever 130, and a
cable 170 for connecting the pivoting lever 130 and the release button 50.
[0022] The fixed plate 110 is coupled to the inner side of the jaw protector 30 as described
above, and a coupling hole 111 may be formed therein for the coupling with the jaw
protector 30 by a coupling member.
[0023] In addition, a hinge protrusion 113 is formed so that the pivoting lever 130 may
be pivotally hinged, and a hooking protrusion 115 is also formed to prevent the pivoting
lever 130 from deviating from the fixed plate 110 when pivoting.
[0024] Moreover, a coupling groove 117 is formed in one side of the fixed plate 110 so that
a coupling protrusion 11 provided at the helmet body 10 may be inserted therein when
the jaw protector 30 and the helmet body 10 are coupled.
[0025] Meanwhile, the hooking protrusion 115 may not only prevent the pivoting lever 130
from deviating but also guide the pivoting lever 130 to rotate when the pivoting lever
130 is pivoting.
[0026] The pivoting lever 130 is coupled to a side of the fixed plate 110 which is oriented
to the inner side of the jaw protector 30, and when being completely assembled, the
pivoting lever 130 is just partially exposed, and the pivoting lever 130 is not entirely
exposed due to the fixed plate 110.
[0027] In addition, the pivoting lever 130 has a hole for the coupling to the hinge protrusion
113 of the fixed plate 110, and a hooking portion 131 is formed at one side thereof
to be hooked by the coupling protrusion 11 provided at the helmet body 10.
[0028] In other words, the coupling protrusion 11 of the helmet body 10 is inserted into
the coupling groove 117 of the fixed plate and is simultaneously hooked by the coupling
protrusion 11 at a position where the hooking portion 131 of the pivoting lever 130
coupled to the fixed plate 110 overlaps with the coupling groove 117 of the fixed
plate.
[0029] In addition, the hooking portion 131 contacting the coupling protrusion 11 may be
formed to have a curved circumference. Referring to Figs. 4 and 5, the coupling protrusion
11 may be inserted into the coupling groove 117 and the hooking portion 131 by pushing
the curved circumference of the hooking portion 131 (see Fig. 5) to pivot the hooking
portion 131 when the jaw protector 30 and the helmet body 10 are coupled.
[0030] Therefore, in order to allow the hooking portion 131 to easily pivot by the pushing
force of the coupling protrusion 11, its circumference contacting the coupling protrusion
11 may have a curved shape as described above.
[0031] A process of coupling the coupling protrusion 11 of the helmet body 10 to the coupling
groove 117 and the hooking portion 131 will be described later in more detail.
[0032] Meanwhile, in this embodiment, the elastic body 150 for restoring the location of
the pivoting lever 130 may employ a torsion spring.
[0033] The torsion spring is frequently used for a device which rotates by a predetermined
angle and then restores its original location. In this embodiment, the pivoting lever
130 rotates by a predetermined angle and then restores its original location in association
with the operation of the release button 50, and thus the elastic body 150 may employ
a torsion spring.
[0034] The elastic body mostly uses a tensile spring or a compression spring, and in an
existing jaw protector fixing device, a tensile spring or a compression spring is
used. However, in the tensile spring and the compression spring, a spring is wound
spirally based on the operating direction of the elastic force and thus has a predetermined
radius perpendicular to the operating direction of the elastic force, different from
the torsion spring employed in the present disclosure. Therefore, the tensile spring
and the compression spring demand a sufficient space for the elastic body, which makes
it difficult to have a slim design.
[0035] Meanwhile, the torsion spring has a very small thickness in a direction perpendicular
to the rotating direction in which the elastic force is applied, which needs a very
small space for the elastic body and accordingly allows a slim design.
[0036] In addition, in order to apply an elastic force with respect to a pivoting direction
of the pivoting lever 130 by means of a tensile spring or a compression spring, a
mechanism for converting a linear motion of the tensile spring or the compression
spring into a rotary motion with respect to the rotation axis of the pivoting lever
130 is separately required. Therefore, the tensile spring or the compression spring
may not be disposed integrally with the pivoting lever 130, which makes it difficult
to have a simple structure.
[0037] However, if the elastic body 150 employs a torsion spring as in this embodiment,
since the torsion spring makes a rotary motion in the arrowed direction as shown in
Fig. 4, the pivoting lever 130 may be directly rotated without performing a process
of converting a linear motion into a rotary motion. For example, the torsion spring
may be disposed to overlap with the rear surface of the pivoting lever 130 with respect
to the rotation axis of the pivoting lever 130.
[0038] At this time, one side of the torsion spring may be connected to the pivoting lever
130 so that an elastic force is transferred in the rotating direction of the pivoting
lever 130, and the other end of the torsion spring may be connected to the fixed plate
110 so that the torsion spring is supported by the fixed plate 110 to transfer an
elastic force to the pivoting lever 130. For example, referring to Figs. 4 and 5,
the torsion spring may be disposed at the rear side of the pivoting lever 130, the
other side has a ring shape and is inserted into a hole (not shown) of the fixed plate
110, and its one side has a ring shape and is hooked by the protrusion of the pivoting
lever 130.
[0039] In addition, if a tensile spring or a compression spring is used in the fixing/releasing
unit 100 of this embodiment, since the spring is not so strong, the spring may lost
its elasticity if it is used many times for a long time.
[0040] Therefore, in this embodiment of the present disclosure, since the torsion spring
is used, the fixing/releasing unit 100 may have a slim design and the helmet may have
a sufficient inner space, thereby ensuring a protector such as a cushion member to
be installed more safely.
[0041] The elastic body 150 employing a torsion spring is provided at the hinge protrusion
113 by which the pivoting lever 130 is hinged to the fixed plate 110, and one of the
fixed plate 110 and the pivoting lever 130 is hooked by the pivoting lever 130.
[0042] Finally, as described above, the cable 170 is configured to connect the pivoting
lever 130 and the release button 50.
[0043] Therefore, if the release button 50 is pulled, the cable 170 pulls one side of the
pivoting lever 130 according to the release button 50 so that the pivoting lever 130
pivots based on the hinged portion.
[0044] The initial location of the pivoting lever 130 is defined as a location when the
hooking portion 131 of the pivoting lever 130 overlaps with the coupling groove 117
of the fixed plate 110, and if the release button 50 is pulled so that the cable 170
pulls the pivoting lever 130, the hooking portion 131 of the pivoting lever 130 pivots
to a position not overlapping with the coupling groove 117 of the fixed plate 110.
[0045] A hooking hole 133 is formed at one side of the pivoting lever 130 so that the cable
170 for connecting the release button 50 is hooked thereto, and one side of the cable
170 is bent into, for example, a "U" shape so as to be hooked by the hooking hole
133 (see Fig. 4).
[0046] In addition, if the fixing/releasing unit 100 is provided at the jaw protector 30
as shown in Fig. 6, the protection cover 70 for protecting the fixing/releasing unit
100 may be coupled to the jaw protector 30.
[0047] Since the protection cover 70 is formed not to disturb the coupling between the fixing/releasing
unit 100 and the coupling protrusion 11, even though the protection cover 70 is coupled
to the jaw protector 30, the fixing/releasing unit 100 may be partially exposed as
shown in the figures.
[0048] A process of opening the jaw protector 30 including the fixing/releasing unit 100
configured as above will be described below.
[0049] A wearer who wears the helmet pulls the release button 50 provided at one side of
the jaw protector 30 in order to open the jaw protector 30 pivotally coupled to the
helmet body 10.
[0050] The jaw protector 30 includes the fixing/releasing unit 100 therein, and the coupling
protrusion 11 of the helmet body is hooked by and fixed to the fixing/releasing unit
100.
[0051] If the wearer pulls the release button 50 provided at one side of the jaw protector
30, the cable 170 connected to the release button 50 pulls the pivoting lever 130
of the fixing/releasing unit in association with the pulling operation of the release
button 50.
[0052] The coupling protrusion 11 of the helmet body 10 is hooked by the coupling groove
117 of the fixed plate 110, and the hooking portion 131 of the pivoting lever 130
is fixed to overlap with the coupling groove 117. Thus, if the cable 170 pulls the
pivoting lever 130, the pivoting lever 130 rotates to spread the hooking portion 131
of the pivoting lever 130, which overlaps with the coupling groove 117, and thus the
coupling protrusion 11 deviates from the coupling groove 117.
[0053] In addition, if the coupling protrusion 11 deviates from the hooking portion 131
and the coupling groove 117, the wearer returns the release button 50 to its original
location, and the pivoting lever 130 is restored to the initial location at which
the hooking portion 131 overlaps with the coupling groove 117, by the elastic body
150 interposed between the pivoting lever 130 and the fixed plate 110, namely the
torsion spring 150 in this embodiment of the present disclosure.
[0054] By doing so, the coupling protrusion 11 of the helmet body 10 is released from the
fixing/releasing unit 110 of the jaw protector 130, and the jaw protector 30 may pivot
to open the helmet body 10.
[0055] In order to couple the opened jaw protector 30 to the helmet body 10 on the contrary,
the wearer pivots the jaw protector 30 to a coupling location and gives a strong pressure
thereto. If so, the coupling protrusion 11 of the helmet body 10 moves into the coupling
groove 117 of the fixed plate 110 while pushing the hooking portion 131 of the pivoting
lever 130.
[0056] In other words, as shown in Fig. 5, if the coupling protrusion 11 pushes the hooking
portion 131 of the pivoting lever 130 in the a direction in contact with the hooking
portion 131, the hooking portion 131 pivots in the b direction by the pushing force
of the coupling protrusion 11.
[0057] In addition, if the coupling protrusion 11 is perfectly adhered to the coupling groove
117, the hooking portion 131 pivots and is restored by the torsion spring 150 to the
initial location where it is overlapped with the coupling groove 117, and at this
time, the hooking portion 131 prevents the coupling protrusion 11 from deviating from
the coupling groove 117.
[0058] By doing so, the coupling protrusion 11 of the helmet body 10 is fixed to the fixing/releasing
unit 100 and the jaw protector 30 is fixed to the helmet body 10.
[0059] Since the helmet having the jaw protector fixing apparatus according to the embodiment
of the present disclosure may open the jaw protector, a helmet wearer may eat food
by opening only the jaw protector without taking off the helmet. In addition, if required,
a user may more easily wear or take off the helmet by opening the jaw protector.
[0060] In addition, since the fixing/releasing unit provided for fixing or releasing the
jaw protector includes the elastic body employing a torsion spring, the fixing/releasing
unit may have a slim design.
[0061] In particular, if the fixing/releasing unit has a slim design, the helmet may have
a sufficient inner space, and thus a protector such as a cushion member for the safety
of the wearer may be installed in an easy and safe way, thereby improving the safety
of the helmet.
[0062] The above disclosure is just for illustration only, and a person having ordinary
skill in the art will understand that the present disclosure may be easily modified
without departing from the spirit or scope of the present disclosure. Therefore, the
embodiments disclosed herein should be understood as examples, not limitative, in
every aspect. For example, any component explained as a single form may be distributed
as various elements, and any components explained as a distributed may also be implemented
as a single form.
[0063] The scope of the present disclosure is defined by the appended claims, and all changes
or modifications derived from the meaning and scope of the claims or their equivalents
should be interpreted as falling into the scope of the present disclosure.
