DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0018] The following descriptions are of exemplary embodiments
only, and are not intended to limit the scope, applicability or
configuration of the invention in any way. Rather, the following
description provides a convenient illustration for implementing
exemplary embodiments of the invention. Various changes to the
described embodiments may be made in the function and arrangement
of the elements described without departing from the scope of the
invention as set forth in the appended claims.
[0019] FIGS. 1 and 1A show an air-flow valve device for a helmet.
The larger opening 101 of the top end of the helmet body 10 is
provided with an air-flow control valve device 20 at the rear end
of the large opening 101. The air-flow control valve body device 20
has a supporting plate extended with a railing plate 21a. The two
sides of the supporting plate 201 are provided with a rain-blocking
plate 201b, which can prevent rainwater from entering the large
opening 101. The supporting plate 201 is also used to enhance the
exertion force of the flow-directing hood 40. The valve body 202 of
the device 20 is a rang block 202a and the two lateral sides are
provided with a valve gate 202b. The top end of the railing block
202a is a threaded member 202d, and the bottom section is a
recessed rail 202c for the reciprocating movement of the railing
plate 201a of the supporting plate 201. The flow directing hood 40
is provided with a long hole 401 at the top face of the helmet. The
long hole 401 allows the threaded member 202d of the railing block
202a to pass through, and a pad 30, a C-shaped elastic plate 31 are
placed onto the threaded member 202d of the railing block 202a.
After that, a circular button 32 having a threaded hole is used to
fasten with the threaded member 202d and by pushing the circular
button 32, the valve body 202 is moved to a position for securing.
The top tension of the C-shaped elastic plate 31 prevents the
movement of the valve body 202.
[0020] The bottom end portion at the two lateral sides of the
helmet is provided with an air-flow hole 103. The air-flow hole 103
is protruded with a pushing block 501 and a hood shell 502 having a
hole 502a. The hole 502a of the hood shell 502 can be blocked by
the pushing block 501 of the valve plate 50 so as to allow air flow
or to stop air flow.
[0021] Referring to FIG. 6, there is shown a warmth keeping cover
70 provided to the device. The cover 70 is a circular body made
from base cloth material and form. The form layer is formed into a
circular pad body 701, and the circumferential edge of the pad body
701 is provided with an adhesive edge 702, and the adhesive edge
702 is spacely mounted with adhesive 703 which can be adhered to
the inner frame edge of the helmet, blocking external air from
entering and therefore a warmth keeping effect is obtained.
[0022] FIGS. 2 and 3 are perspective view and sectional schematic
view showing the air-flow state of the air-flow control valve
device in accordance with the present invention. As shown in the
figure, when the circular button 32 is pushed forward, the railing
block 202a moves together, the valve gate 202b at the two lateral
sides of the rang block 202a and the rain-blocking plate 201b at
the two lateral sides of the supporting plate 201 form a gap
allowing hot air to release. The valve plate 50 at the end portion
of the two sides of the helmet 10 is pushed by the pushing block
501 to expose the air hole 103 allowing the air to flow into the
interior of the helmet, forming a convection current (as shown in
FIG. 3). The air within the helmet and the hot air will flow via
the large opening 101 of the hole path 601 via various air holes 60
and then released, and pass through the gap between the valve gate
202b and the rain-blocking plate 201b to release.
[0023] FIGS. 4 and 5 are perspective view and sectional schematic
view showing the air-blocking situation of the valve device of the
present invention. As shown in the figure, the circular button 32
is pushed backward and the railing block 202a is moved together.
The valve gate 202b and the ram-blocking plate 201b at the two
lateral sides of the supporting plate 201 are closed together and
sealed to stop air from discharging. The valve plate 50 at the
bottom section of the two lateral sides of the helmet 10 makes use
of the pushing block 501 to close the air hole 103 so that air will
not flow in, forming into a sealed warmth-keeping interior of the
helmet. Referring to FIG. 5, the hot air within the helmet can only
be discharged via various air holes 60 to the air path 601 and via
the large opening 101 to the valve body 202. The gap between the
valve gate 202b and the rain-blocking plate 201b is blocked and
therefore the air-flow is stopped and the warmth air is kept.
[0024] FIG. 6 is a sectional schematic view showing the warmth
keeping cover the present invention. The cover 70 is a circular
body made from base cloth material and foam. The form layer is
formed into a circular pad body 701, and the circumferential edge
of the pad body 701 is provided with an adhesive edge 702, and the
adhesive edge 702 is spacely mounted with adhesive 703, which can
be adhered to the inner frame edge of the helmet.
[0025] FIG. 7 is a sectional schematic view of the air-blocking
situation of the control valve body with the warmth-keeping cover.
As shown in the figure, when at an extremely cold weather, a
warmth-keeping cover 70 is needed and the edge 702 is spacely
mounted with a plurality of adhesive 703 to mount onto the internal
edge of the helmet so as to fully cut off the external air to enter
the helmet. The effect of the warmth keeping is obtained and there
is no loss of heat from the head of the user.
[0026] In view of the above, it is understood that the helmet of
the present invention provides a warm effect during a cold
surrounding weather and a cooler effect in a hot weather.
[0027] It will be understood that each of the elements described
above, or two or more together may also find a useful application
in other types of methods differing from the type described
above.
[0028] While certain novel features of this invention have been
shown and described and are pointed out in the annexed claim, it is
not intended to be limited to the details above, since it will be
understood that various omissions, modifications, substitutions and
changes in the forms and details of the device illustrated and in
its operation can be made by those skilled in the art without
departing in any way from the spirit of the present invention.
