Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
This invention relates to shoes, and, more particularly, to a multi-function variable healthcare shoe.
2. Description of Related Art
Shoes exhibiting a ventilation effect have some structural problems, even if they may be granted a patent. For instance, a couple of dents and protrusions are designed to provide a massage function. However, such dents and protrusions circulate the air in the shoes, and are in contact with the skin of feet only, without deeply massaging the arch and fascia of feet. When the dents and protrusions perform the massage function, the temperature of the air in the shoes increases, which adversely affect the health of the feet.
Some patents, including U.S. Pat. No. 4,633,597, JP013203, CN ZL92233539.7, TW99876, TW64069, IT99876, DE9214653.8, KR29-221886, provide a foot pad having an air sack that obeys pumping principles.
However, some of the foot pads disclosed in the above patents does not establish a ventilation system, and still suffer from poor air circulation and cannot achieve the ventilation and massage effects effectively.
Therefore, how to overcome the drawbacks of the prior art is becoming an urgent issue in the art.

SUMMARY OF THE INVENTION

The present invention is provided to improve men's health, focus on a foot contact surface, and employ ergonomics and pumping principles, in order to realize multi-function healthcare shoes that can take care of men's feet. The inventor, after a long period of time of thorough research, integrates and improves a ventilation system, which enables air to flow smoothly at the same direction from inner sides of the feet to outer sides of the feet, like waves propagating continuously. Therefore, air can keep flowing in and out the shoes. The multi-function healthcare shoes according to the present invention further provide a massage function, which can promote blood circulation and metabolism.
The present invention provides a multi-function variable healthcare shoe that includes: a foot pad having an air sack that obeys pumping principles, an intake valve disposed on an inner side of a rear bottom portion of the air sack, and an exhaust valve disposed on an inner side of a toe portion of the air sack. A plurality of non-slip protrusions are disposed in front of the air sack. A curved and protruded air guide turns to an external portion of a venting slot for guiding air to flow through a slot disposed on a bottom portion and a protection edge to a topline to form a ventilation system. Therefore, air keeps flowing through and ventilating in the multi-function variable healthcare shoe. The foot pad has a massage cover. The foot pad is full-sized or half-sized. Low leather casual shoes that have an elastic ribbon around a topline thereof are improved to be loafer shoes, and lace shoes, such as low leather shoes and low sport shoes, are improved to be tongue sleeve shoes.
According to the multi-function variable healthcare shoe, the ventilating and breathing foot pad employs a full-sized palm-shaped air sack foot pad as a basic foot pad according to the present invention. The half-sized multi-function variable foot pad comprises: 1. an invisible raised structure; 2. a foot pad having an adjustable massage cover; and 3. a palm-shaped design having a variety of functions. The palm-shaped design having a variety of functions includes: A. a shoe bottom having a heel or a thick enough rear portion that is designed with a fry-pan-shaped depression and an elastic pad bottom; B. a hard metal pad bottom and a foot pad with a hole for a thumb screw to be inserted and rotate therein to adjust the massage strength; and C. an elastic member that can be filled in the middle portion of the full-sized pad bottom to adjust the elasticity and air ventilation. The full-sized pad bottom includes designs above the shoe bottom (including a top-bottom bonding design).
According to the multi-function variable healthcare shoe, an elastic ribbon of a low leather casual shoe is likely malfunctioned, which is a design error and can be amended by a pneumatic block, a compressive block or a pocket block, and is changed to be a loafer shoe.
According to the multi-function variable healthcare shoe, a low lace leather shoe and a low lace sport shoe is provided with an invisible shoehorn. A flat hook with two ends bonded with metal sheets cooperates with an elastic rubber strip having matched length, thickness and width. The round hole of the original lace is changed to be a rectangle hook hole, for the elastic band hook to be inserted therein. A portion of pulling force of the elastic band is used to depress a leather face on two ends, and the remaining stronger pulling force of the elastic band is strong enough to handle the basic fixture function when a user wearing the shoe is walking. The elastic hook band has one end using a moveable hook and the other end using a fixture.

A multi-function variable healthcare shoe of a first embodiment according to the present invention comprises a full-sized foot pad 1 having a palm-shaped air sack 11, as shown in FIGS. 1A and 1B. The foot pad 1 comprises a pad body 10, an air sack 11, a plurality of protruded air guide 12, and a slot 13.
The pad body 10 is designed to comply with the sole, arch and fascia elasticity of the foot, to become a full-sized foot pad 1. The pad body 10 defines a top face 10 a and a bottom face 10 b, a left side (that is an inner side with respect to the orientation of the foot, and is hereinafter referred to as “an inner side 10 c”), a right side (that is an outer side with respect to the orientation of the foot, and is hereinafter referred to as “an outer side 10 d”), a front end 10 e, and a rear end 10 f. The inner side 10 c, the outer side 10 d, the front end 10 e, and the read end 10 f form a side surface of the pad body 10. The pad body 10 is divided into a heel portion 100 (that carries heel with respect to the orientation of the foot), a toe portion 102 (that carries toes with respect to the orientation of the foot) opposite to the heel portion 100, and a middle portion 101 (that carries sole with respect to the orientation of the foot) disposed between the heel portion 100 and the toe portion 102. The pad body 10 further comprises a protection edge 103 on a side surface thereof. For example, the inner side 10 c, the outer side 10 d, the middle portion 101 and the rear end 10 f of the pad body 10 have a consecutive protection edge 103 on their edges.
The air sack 11 obeys pumping principles. The middle portion 101 is bulged with the air sack 11, and the air sack 11 protrudes on the top face 10 a to become the palm-shaped air sack 11. The air sack 11 and the shoe bottom (not shown) form a compressive space F, as shown in FIG. 1C. Preferably, the air sack 11 extends to the inner side 10 c of a portion of the heel portion 100. The air sack 11 can be integrated with the pad body 10. An intake valve 110 is disposed on the inner side 10 c of an rear bottom portion of the air sack 11, and an exhaust valve 111 is disposed on the inner side 10 c of a toe portion of the air sack 11. The intake valve 110 is disposed on the side surface in the bottom portion, is in a concave shape (to form, together with the shoe bottom, an elastic intake mechanism), and is adjacent to the heel portion 100. The exhaust valve 111 is an elastic valve, disposed on the top face 10 a, and is adjacent to the toe potion 102. The intake valve 110 and the exhaust valve 111 have a valve structure, as shown in FIG. 1A. The protection edge 103 has another exhaust valve 103 a corresponding to the intake valve 110 (or the exhaust valve 111), such that the foot pad 1 has an appropriate size of exhaust valve.
The air guide 12 is disposed in front of the air sack 11, on the top face 10 a of the pad body 10 corresponding to the exhaust valve 111 and in the toe portion 102, and curvedly extends toward the inner side 10 c and the outer side 10 d, allowing one end to the air guide 12 to be adjacent to the exhaust valve 111, so as to guide the air from the air sack 11 to the outer side 10 d.
The slot 13 is disposed on the bottom face 10 b and the protection edge 103 of the outer side 10 d, to guide the air of the outer side 10 d through a topline to a region outside of the shoe, in a direction indicated by an arrow t showing in FIG. 1A. Preferably, the slot 13 extends to the bottom face 10 b, to guide the air of the bottom face 10 b to a region outside of the shoe. A venting slot 130 penetrates the pad body 10, and communicates with the periphery of the slot 13 and the air guide 12, to guide the air of the top face 10 a guided by the air guide 12 to the slot 13 and to a region outside of the shoe. In another embodiment, the slot 13 has a raised venting conduit 13 a, and vents can be disposed above the side surface of the shoe.
As shown in FIG. 1A, the top face 10 a of the toe portion 102 has a plurality of non-slip protrusions 14 that provide massage and non-slip effects.
As shown in FIG. 1B, the bottom face 10 b of the pad body 10 further has a fragrant material receiving space 15 near the toe portion 102, for deodorization materials such as a fragrant material and other functional materials to be received therein.
