A Multi-function Ventilation Shoe Structure This invention relates to a shoe structure, which can ventilation from manv channel and holes.

Most of the conventional shoes have the drawbacks of mal-circulation of air and a hot effect, which cause a user to feel un-comfortable aside from un-sanitary condition; foot diseases to a user are susceptible to resulting (such as Hong-Kong foot). So far, none of the conventional shoes can overcome the Hon-ong foot disease.

This invention relates to a multi-function ventilation shoes structure, which is designed in accordance with the nature of substance, the human engineering and an air pump theory. The major part of invention is a full sized (or a half-section type of) foot pad thereof. The mid-and-rear portion of the foot pad is furnished with a compressing chamber; the inner side of the foot pad has an arcuate intake piston; an exhausting piston is furnished in the front part of the compressing chamber to form into an automatic intake piston and an exhaustion piston respectively; further, nearing a guard band, there are an intake channel, an exhausting channel and vamp holes. All the aforesaid parts can have a shoe provided with an automatic intake and exhausting effect to produce an air circulation in a shoe upon a user walking.

The prime object of the present invention is to provide a means to overcome the problems of hot air and noncirculation in a conventional shoe upon a user walking. By means of the present invention, a jetting air will be produced in a shoe so as to exchange air and to overcome hat air therein to let a user have a comfortable walking.

Referring to FIGS. 1 and 2, the embodiment -1 of the present invention comprises mainly a foot pad 10, which includes a lower front part and a higher rear part (a palmshaped member) to form into an elongate compressor top side 25, and includes a compressor top side 25 and a compressor bottom side 11. A compressing chamber 12 includes a slantingdown front portion (i.e., a human engineering type of exhausting piston), and a sloping mid-and-rear portion having a lower front and a higher rear parts, and becoming a foldable arcuate part. When the compressing chamber 12 is compressed, the air in the chamber will flow out through several air jetting holes 14 on the top of the foot pad 10, and through several ventilation channel holes 19 of several ventilation channels 18 on the top of the foot pad (as shown in FIG. 2).The front part of the compressing chamber 12 can exhaust air upon not being pressed completely, and will be closed upon being pressed completely; therefore, it is named an exhausting piston 13. The outside of the mid-and-rear portion of the food pad 10 has a guard band 15, in which an intake channel 16 is furnished; the intake channel 16 is in communication with an arcuate intake piston 17; when a user lifts the shoe to step forwards, the intake channel 16 will take in air; when one's foot steps down to press the pad, the air intake is discontinued. By means of the exhausting piston 13, the compressing chamber, during a user walking, works like a pump to have the air in shoes exchanged back and forth. The front inner side of the exhausting piston 13 has an exhausting channel 20 extended to the inner side of the guard band 15.The exhausting channel 20 can exhaust air in shoes simultaneously with an inner-side exhausting hole 62.

If the front vamp is furnished with a exhausting hole, the air in shoes can be exhausted through a front vamp exhausting hole 63, which can be furnished separately or together with the inner-side exhausting hole 62 (as shown in FIG. 3). The front section of the exhausting channel is furnished with one or two exhausting channel holes 21. A fragrant agent chamber 22 is furnished in a suitable part of the foot pad, being in communication with the compressing chamber 12. The chamber 22 is to be filled with a small soft or hard type of fragrant agent or a sterilizing agent so as to provide a fragrant smell or a sterilizing effect in shoes.

A U-shaped waterproof parts chamber 23 is furnished beside the guard band for storage several one-side glue patches 24, which each has a diameter slightly bigger than that of an intake hole or an exhausting hole. In the event of raining, the patches will be used glued to the intake holes 61, the exhausting holes 62 and 63 respectivelv on the shoe body 60 for watertight purpose. The size of the string end ring 64 is equal to that of the intake and exhausting holes, the string end rings 64 can be used for waterproof purpose instead of using one-side glue patches 24.

FIG. 3 is a side view of a shoe according to the present invention, in which the parts 60, 61, 62, 63 and 64 have been described in FIGS. 1 and 2, and therefore no details thereof are given; the arrows in FIG. 3 indicate the intake and exhausting directions of the shoe.

FIGS.4 and 5 illustrate a perspective view and a top view of another embodiment according to the present invention, which comprises a foot pad 30 having a bottom side, a flat bottom 31, a compressing chamber 32 in the midand-rear portion of the pad, an intake channel 33 nearing the guard band, an arcuate intake portion 34 under the lower end of the intake channel, an exhausting channel 35 in the front of and inside the shoe, and an air jetting port 36 in the front of the compressing chamber and through the top of the foot pad. Since the air jetting port 36 can provide air circulation to the front foot palm, and can be closed upon the front foot palm pressing thereon, the air jetting port 36 becomes an automatic exhausting piston conforming to the human engineering requirement. The port 36 and the arcuate intake piston 34 are formed into an automatic pump type of compressing foot pad. The arcuate front edge of the exhausting channels 35 are provided with three exhausting holes 37 through the foot pad. When the air inside the compressing chamber is flowing out of the air jetting port 36, the air inside the shoe will be forced to exhaust out of the exhausting holes 37 along the exhausting channel 35, and through the exhausting holes 62 and 63 so as to fulfill a cooling and dehumidifying function in shoes. FIG.5 illustrates a raised portion in the mid-and-rear portion of the foot pad, and it is a compressor top side 38 with a sloping surface.

FIGS. 5 and 7 illustrate a perspective view and a side view respectively of the embodiment of a half-section foot pad according to the present invention; such a half-section foot pad 40 not only can provide a pump type of air circulation by means of an automatic exhausting piston function in a shoe, and can be used in sports shoes with removable foot pads (for shoes having no holes, a user may make holes in the shoes), but also can be used in shoes without removable foot pads and without ventilation means, or in shoes that have a low vamp. Such a pad 40 has a higher rear guard band 41 to prevent the pad 40 from moving forwards. The arcuate front end thereof has a V-shaped connection angle 42 to facilitate connection with the original foot pad or the inner sole of a shoe.The front end of the compressing chamber 44 has an-shaped air jetting port 43, of which the outer side forms a larger and wider air jetting port. The rear side of the port 43 is in communication with the compressing chamber 44. The bottom side on both sides of the front end of the pad is furnished two storage chambers 45 being in communication with the compressing chamber 44; the two storage chambers 45 are used for storing a sterilizing agent and a fragrant agent respectively. The intake channel 46 on the inner guard band is in communication with the arcuate intake piston 47 in the compressor bottom side 50. The compressing chamber 44 can take in fresh air through a channel connected with the shoe throat (it is connected with the intake hole of s boot-shaped shoe).On the outer bottom side of the foot pad and nearinq the guard band, an exhausting channel 48 is furnished, and is extended, to the shoe throat (it is connected with an exhausting hole in a boot-shaped shoe). The outer bottom of the compressing chamber 4d has a compressor bottom side 50 without channel and intake piston. The half-section type of compressing foot pad would cause the arcuate intake piston 47 and the compressor top side to raise upon the shoe stepping up so as to let the compressing chamber 44 take in fresh air fully via the intake piston.When the shoe steps down, the compressor top side is pressed down, and the arcuate intake piston is flattened first to close the air in the compressing chamber 14; then, the air in the chamber is compressed continuously to jet out through the air jetting port 43 to flow towards the front palm portion (insider the shoe). When the front palm steps down completely, the air jetting port will be closed to form into an exhausting piston as required by human engineering effect. The air inside the shoe is also compressed into the exhausting channel to flow out of the shoe throat before the front palm being pressed down completely. If the shoe is a sports shoe, the air will be exhausted through the ventilation holes or special designed exhausting holes.

FIGS. 8 and 9 illustrate the sectional views of the aforesaid embodiments respectively of the present invention.

Each of the foot pads has a compressor top side with a shock-absorbing function, and therefore it is should be made of foam-rubber or the like. The rear top of the compressor top side must be thicker than other part so as to have a better shock-proof function. The inside of the compressing chamber can also be filled with a ventilating or nonventilating elastic substance (not shown) so as to provide a better shock-absorbing effect to meet weather or personal requirement.

The major part of the multi-function type of ventilating shoe structure according to the present invention is the foot pad thereof. The foot pad is designed to include a compressor top side and a ventilation channel system, which can function together with the inner bottom side of a shoe to provide an intake and exhausting piston, and compressing effect. By means of the human engineering and the limited space in a shoe, the embodiment of the present invention has reached a high criteria in terms of simplicity, scientific, beauty and artistic requirements. The foot pad can be manufactured by using a foam rubber material with an integrated molding method so as to have a fast production, and to save cost for meeting the economic and industrial requirements.The functions of the present invention are that it can automatically provide a jetting air to a user's palm for exchanging air in a shoe to remove the hot and humidity in a shoe, and for shock-proof, waterproof and deodorizing functions; further, it can provide a user's to have a better blood circulation, a better health and comfortable feeling.

The present invention also has the features as follow: (1) Having a superior major part, i.e., the foot pad, which is easy to manufacture through a mass production method to supply a shoe factory; the consumer can replace the shoes and foot pads any time without affecting the functions of the original shoe sole and vamp.

(2) Having a full employment on the material, theory and human engineering together; for instance, the foot pad with a compressing chamber has fully emploved the elasticity of a material, and the human engineering to provide an intake and exhausting piston function to have the air in a shoe exchanged and circulated.

(3) Full utilization of the space and parts inside a shoe has been made; for instance, the space in the mid-andrear portion in a shoe has been so designed that it can be used together with the compressing chamber of the pad, the sole and the vamp, i.e., the foot pad being made the most of its function designed.

In brief, the present invention has made a breakthrough in function and manufacture, and such features are never known and found in the conventional foot pads, and therefore it is deemed a practical and multi-function foot pad.
