Description
TITLE OF THE INVENTION:
motor cycle helmet NAME OF INVENTOR:
Wei-Hsien Tsai FIELD OF THE INVENTION
The present invention relates to a motor cycle helmet and, in particular, a ventilated motor cycle helmet.
P~7ROUND OF THE INVENTION
Helmets are designed to protect the head preventing it from major impacts, and thereby safeguard the life of the wearer. When wearing these helmets, the entire head is covered in the shell of the helmet, which is made of non-porous material. Unfortunately, the head emits heat, which causes discomfort to the wearer.
To solve this problem, manufacturers of helmets have placed a plurality of vents in helmets. Preferably each vent has a movable closure plate. When it is raining outside, the movable closure plate can be closed to prevent water from getting into the body of the helmet. But, when it is raining and hot outside, the closed movable closure plate stops the air flow inside the body of the helmet. It also causes the interior to steam up creating a stuffy and hot feeling. The visor of the helmet will also fog up, seriously impairing the wearers visibility.
Because of the shortcomings outlined above, namely: the stuffy and hot air inside the helmet, and the reduced visibility due to the fogging up of the visor, the manufacturers have come up with a second kind of helmet. This kind of helmet has a live conducting device on the top of the body of the helmet. The live conducting device uses the principle of induction to regulate and to control the interior temperature of the body of the helmet. This design also has its limitations. It requires the assembling of many parts.
The interior of the body of the helmet is not equipped with ventilation ducts. Thus, the air in the interior is not well circulated, causing negative effect. In addition, because the live conducting device is, typically, located on the middle top part of the body of the helmet, rain water can easily seep in causing some internal parts to be damaged by moisture, thus shortening the life of the helmet.
Because of the shortcomings attached to the two kinds of helmets mentioned previously, a third kind of helmet was developed. This kind of helmet has on the body of the helmet a few heat sinks for heat dissipation with opening and closing function. Utilizing the opening and closing regulation of the heat sinks, the amount of external air entering the body of the helmet can be controlled. The internal temperature of the body of the helmet can then be maintained within the appropriate range. But, because those heat sinks with temperature control function are distributed on various places on the surface of the body of the helmet, plus the installation of each heat sink involves drilling a set of holes on the body of the helmet, the degree of difficulty in the process of production is greatly increased. The heat sinks for heat dissipation are not able to sense the external weather conditions, they can only respond to the interior temperature of the body of the helmet to carry out the single function of opening and closing. These heat sinks are, typically, located on the top part of the body of the helmet. So, when it rains, if the heat sinks are opened, rain water can easily seep into the interior of the body of the helmet, which is not practical for use.
To summarize, all three kinds of helmets mentioned previously, have in common these shortcomings: letting rain water seep into the helmet; moisture build up; stuffy and hot interior; fogged up visors. These shortcomings either shorten the life of the helmet or cause discomfort to the wearer.
SUMMARY OF THE INVENTION
What is required is an improved manner of ventilating a motor cycle helmet.
According to the present invention there is provided a motorcycle helmet which includes an impact resistant body having a head receiving cavity. The head receiving cavity contains an air conduction section having an inlet and an outlet through which air draw from outside of the body passes.
A thermoelectric cooler is connected to the air conduction section. The body has a ventilation section, which contains at least one ventilating duct in which is disposed a fan. The ventilation section is connected to the conduction section.
The body has an electric supply section which supplies the energy required to operate the fan in the ventilation section and the thermoelectric cooler.
The motor cycle helmet, as described above, can be used in both cold and hot weather. It is preferred that the thermoelectric unit has a thermostat which assists in controlling and regulating temperature. The combined operation of the ventilation section and the air conduction section ensures the free flow of air inside the head receiving cavity of the body, thus promoting user comfort and providing a clear and non-foggy visor.

DE~ATT~n DESCRIPTION OF THE rn~nn~v EMBODIMENT
The preferred embodiment, a motor cycle helmet generally identified by reference numeral 10, will now be described with reference to FIGURES 1 through 9.
30Referring to FIGURE 1 which is labelled as PRIOR ART, there is illustrated a kind of ventilated helmet. This kind of helmet has a vent (111) on the front top of the body of the helmet (110). Near the chin area there is another vent (112).
On the front top vent (111) a movable plate (113) is installed to function as a switch. When it is raining outside, the 217126~
movable plate can be closed to prevent water from getting into the body of the helmet (110). But, when it is raining and hot outside, the closed movable plate (113) will stop the air flow inside the body of the helmet, it will also cause the interior to steam up creating a stuffy and hot feeling. The visor of the helmet (114) will also fog up, this seriously impairing the wearers visibility.
Referring to FIGURE 2 which is labelled as PRIOR ART, there is illustrated a second kind of ventilated helmet. This kind of helmet (210) has on the top of the body of the helmet (211) a live conducting device (212) which uses the principle of induction to regulate and control the interior temperature of the body of the helmet (211). With this design, the interior of the body of the helmet (211) is not equipped with ventilation ducts. Thus, the air in the interior is not well circulated. In addition, because the live conducting device (212) is located on the middle top part of the body of the helmet (211), rain water can easily seep in causing some internal parts to be damaged by moisture, thus shortening the life of the helmet.
Referring to FIGURE 3 which is labelled as PRIOR ART, there is illustrated a third kind of helmet was developed (310). Helmet (310) has on the body of the helmet (311) a few heat sinks for heat dissipation (312) which open and close.
Utilizing the opening and closing regulation of the heat sinks (312), the amount of external air entering the body of the helmet (311) can be controlled. The internal temperature of the body of the helmet (311) can then be maintained within the appropriate range. But, because those heat sinks (312) with temperature control function are distributed on various places on the surface of the body of the helmet (311), plus the installation of each heat sink involves drilling a set of holes on the body of the helmet, the degree of difficulty in the process of production is greatly increased. The heat sinks for 217126~
heat dissipation (312) are not able to sense the external weather conditions, they can only respond to the interior temperature of the body of the helmet (311) to carry out the single function of opening and closing. These heat sinks (312) are located on the top part of the body of the helmet (311).
So, when it rains, if the heat sinks (312) are opened, rain water can easily seep into the interior of the body of the helmet (311), which is not practical for use.
Referring to FIGURE 4, there is illustrated helmet (10) which has a temperature-control instrument (20) and an air conduction section (40). Helmet has a body (10), same as illustrated before, and a cavity (11). The outside surface is closed and smooth (13), the body of the helmet (10) is made of durable material tested to stand up to collision. The inside of the body is the head protection section made of soft material (12). This material, considering the cost to make it, is usually a kind of sponge-foam.
Referring to FIGURES 5 and 6, the temperature-control instrument (20) contains a Thermoelectric cooler, (hereinafter referred to as a "TEC"). In the sample the TEC used is manufactured by MARLOW Industries Co., the product number is CTR-4. This temperature-control instrument (20) is located at the back of the body of the helmet (10). The temperature-control instrument spans an area called the safety zone, which spans from the back bottom edge, and extending to a "collision testing safety line at the back of the head". In the event the helmet hits the ground, or the motorcycle rider falls onto the ground, causing collision to the body of the helmet, the probability of the temperature-control instrument being damaged is reduced, this lengthening the life of the temperature-control instrument. The "collision testing safety line at the back of the head" means the tangential point to the most convexed section at the back of the body of the helmet. Also because the temperature-control instrument (20) is located at the slightly concaved portion of the lower back of the body of the helmet, and the temperature-control instrument-s side facing the outside is covered by the closed surface of the body of the helmet, rain water cannot enter to shorten the life of the helmet, or to produce moisture inside the body of the helmet.
Referring to FIGURES 6 and 7, a ventilation section (30) is located inside of the body of the helmet (10). Located on the two sides of the temperature-control instrument (20), there are ventilating ducts (31, 32). On the outside of the ventilating ducts (31, 32), there are fan fixtures (33, 34).
In order to take into consideration the safety of the user, and the stability of his/her mental condition which the vehicle (motorcycle) is running, the sample of the helmet here uses miniature fans for the fan fixtures (33, 34). These fans are driven by silent miniature motors, to reduce the noise produced when the motor is rotating. Noise produced usually influences the hearing of the user, thus influencing the mental condition of the motorcycle rider.
As illustrated in FIGURES 4 through 6, the air conduction section (40) is located in the inside of the body of the helmet. It includes at the centre a temperature-control instrument (20) and from this temperature-control instrument (20) there are equipped multi-branch air ducts (41). At the bottom of the body of the helmet (10) using the temperature-control instrument as a divider, there are inlet pipe (42), and exhaust pipe (43). The inlet pipe (42) and the exhaust pipe (43) are connected respectively to the ventilating ducts (31, 32) of the ventilation section (30). When fan fixture 33 is running, it creates a forced convection phenomenon, which increases the effect of bringing in external cold air into the body of the helmet (10) via the inlet pipe (42). At the same time, the convection phenomenon also increases the effect of getting rid of the hot air from inside the body of the helmet (10) into the atmosphere via the exhaust pipe (43). When fan fixture 34 is running, it can pump in external cold air, while pumping out the hot air via the exhaust pipe (43), to achieve the effect of cooling to the user. To maintain aesthetic sense of the helmet, the fan fixture 34 is located in the inside of the head protection section (12) out of sight. The design of the air conduction section (40) does not have specific limitations, as long as it facilitates air flow. In this sample, the air ducts (41) extend radially and are dove-tailed onto the sponge-foam material of the head protection section (12) inside the body of the helmet (10). The porous sponge-foam can also ætrengthen the effect of the air flow inside the body of the helmet (10). So, the air conduction section (40) causes air to flow freely inside the body of the helmet (10) preventing the body of the helmet from getting stuffy, hot, and foggy. And because the air inside is flowing freely, the visor will not become fogged up. In order to strengthen the cool down and heat up effects of the temperature-control instrument (20) onto the interior of the body of the helmet (10), the two sides of the temperature-control instrument (20) are equipped with metal heat sink plates (21), to smoothly dissipate the cold or hot air produced by the temperature-control instrument into the interior of the body of the helmet. The plates can also smoothly dissipate the hot air produced inside the body of the helmet onto the outside atmosphere, thus enhancing the temperature control effect of the new and practical helmet.
There are no limitations imposed on the material used to make the metal heat sink plates. There are no limitations imposed on the shape of the plates. The plates are to be able to dissipate heat, and are to be fixable on the temperature-control instrument. For this sample, taking the cost to make the plates into consideration, the inexpensive aluminum heat sink plates are used.
The temperature-control instrument (20) and the ventilation section (30) depend on an external electric supplier to operate, so, as illustrated in FIGURE 8, near the 217126~
temperature-control instrument (20) inside the body of the helmet (10), there is equipped an electric supply section (22) which is hidden inside the head protection section (12) (not shown in the figure). The form of electrical source providing for the electric supply section (22) is not specifically limited. It can, as shown in FIGURE 8, come directly from a battery within, or as shown in FIGURE 9, it can come from an external electric supplier (22) which is plugged into an outside socket, connected to the motorcycle's storage battery.
In order to control the operation of the temperature-control instrument (20) and the ventilation section (30) a switch (35) is put on the outside surface of the body of the helmet (10).
There is no specific requirement as to where to put the switch (35). It may be placed on any position suitable for operation by the user. As illustrated in FIGURE8 8 and 9, the switch (35) is placed on the outside surface of the ventilation section (30).
The interior of the body of the helmet (10) is equipped with a thermostat (24), to work together with the temperature regulation and control function of the temperature-control instrument (20), as illustrated in FIGURE 4 . The thermostat (24) is connected to the thermoelectric cooler TEC, to measure with accuracy the internal temperature of the body of the helmet (10) so the temperature-control instrument can proceed the regulation of temperature according to the result measured.
To summarize, this new and practical helmet, adjustable to different temperatures, to be used in both cold and hot weather, utilizes a temperature-control instrument and its ability to control and to regulate changing temperatures accordingly. This helmet also uses the combined function of a ventilation section (30) and an air conduction section (40), to ensure free air flow inside the body of the helmet (10) thus giving the user a comfortable, fresh air, and a clear and non-foggy visor.
It will be apparent to one skilled in the art that modifications may be made to the illustrated embodiment without departing from the spirit and scope of the invention as hereinafter defined in the Claims.

On the front top vent (111) a movable plate (113) is installed to function as a switch. When it is raining outside, the 217126~
movable plate can be closed to prevent water from getting into the body of the helmet (110). But, when it is raining and hot outside, the closed movable plate (113) will stop the air flow inside the body of the helmet, it will also cause the interior to steam up creating a stuffy and hot feeling. The visor of the helmet (114) will also fog up, this seriously impairing the wearers visibility.
Referring to FIGURE 2 which is labelled as PRIOR ART, there is illustrated a second kind of ventilated helmet. This kind of helmet (210) has on the top of the body of the helmet (211) a live conducting device (212) which uses the principle of induction to regulate and control the interior temperature of the body of the helmet (211). With this design, the interior of the body of the helmet (211) is not equipped with ventilation ducts. Thus, the air in the interior is not well circulated. In addition, because the live conducting device (212) is located on the middle top part of the body of the helmet (211), rain water can easily seep in causing some internal parts to be damaged by moisture, thus shortening the life of the helmet.
Referring to FIGURE 3 which is labelled as PRIOR ART, there is illustrated a third kind of helmet was developed (310). Helmet (310) has on the body of the helmet (311) a few heat sinks for heat dissipation (312) which open and close.
Utilizing the opening and closing regulation of the heat sinks (312), the amount of external air entering the body of the helmet (311) can be controlled. The internal temperature of the body of the helmet (311) can then be maintained within the appropriate range. But, because those heat sinks (312) with temperature control function are distributed on various places on the surface of the body of the helmet (311), plus the installation of each heat sink involves drilling a set of holes on the body of the helmet, the degree of difficulty in the process of production is greatly increased. The heat sinks for 217126~
heat dissipation (312) are not able to sense the external weather conditions, they can only respond to the interior temperature of the body of the helmet (311) to carry out the single function of opening and closing. These heat sinks (312) are located on the top part of the body of the helmet (311).
So, when it rains, if the heat sinks (312) are opened, rain water can easily seep into the interior of the body of the helmet (311), which is not practical for use.
Referring to FIGURE 4, there is illustrated helmet (10) which has a temperature-control instrument (20) and an air conduction section (40). Helmet has a body (10), same as illustrated before, and a cavity (11). The outside surface is closed and smooth (13), the body of the helmet (10) is made of durable material tested to stand up to collision. The inside of the body is the head protection section made of soft material (12). This material, considering the cost to make it, is usually a kind of sponge-foam.
Referring to FIGURES 5 and 6, the temperature-control instrument (20) contains a Thermoelectric cooler, (hereinafter referred to as a "TEC"). In the sample the TEC used is manufactured by MARLOW Industries Co., the product number is CTR-4. This temperature-control instrument (20) is located at the back of the body of the helmet (10). The temperature-control instrument spans an area called the safety zone, which spans from the back bottom edge, and extending to a "collision testing safety line at the back of the head". In the event the helmet hits the ground, or the motorcycle rider falls onto the ground, causing collision to the body of the helmet, the probability of the temperature-control instrument being damaged is reduced, this lengthening the life of the temperature-control instrument. The "collision testing safety line at the back of the head" means the tangential point to the most convexed section at the back of the body of the helmet. Also because the temperature-control instrument (20) is located at the slightly concaved portion of the lower back of the body of the helmet, and the temperature-control instrument-s side facing the outside is covered by the closed surface of the body of the helmet, rain water cannot enter to shorten the life of the helmet, or to produce moisture inside the body of the helmet.
Referring to FIGURES 6 and 7, a ventilation section (30) is located inside of the body of the helmet (10). Located on the two sides of the temperature-control instrument (20), there are ventilating ducts (31, 32). On the outside of the ventilating ducts (31, 32), there are fan fixtures (33, 34).

The inlet pipe (42) and the exhaust pipe (43) are connected respectively to the ventilating ducts (31, 32) of the ventilation section (30). When fan fixture 33 is running, it creates a forced convection phenomenon, which increases the effect of bringing in external cold air into the body of the helmet (10) via the inlet pipe (42). At the same time, the convection phenomenon also increases the effect of getting rid of the hot air from inside the body of the helmet (10) into the atmosphere via the exhaust pipe (43). When fan fixture 34 is running, it can pump in external cold air, while pumping out the hot air via the exhaust pipe (43), to achieve the effect of cooling to the user.
