The hooked pad is defined and divided into a bottom portion, long end portion, and short end portion. The bottom portion connects with the long end portion and the short end portion, with the bottom portion corresponding in position to a heel, the long end portion corresponding in position to the medial longitudinal arch, and the short end portion corresponding in position to the lateral longitudinal arch. Due to its special structure, the insole provides sufficient support, renders walking or running smooth, gives comfort to the foot, makes lengthy standing less tiring, has a long service life, and incurs low production costs.
Description
- The present invention relates to insoles and, more particularly, to an insole which provides sufficient support to not only enable a shoe wearer to stand comfortably and walk comfortably, but also provide a buffer for foot treading, thereby enhancing the practicability of the insole.
- A human being's feet bear her or his body weight, regardless of whether s/he is standing, walking, or running. With health awareness on the rise, an insole is often placed in a shoe to protect the human foot therein. In view of this, shoe manufacturers are keen to make insoles lighter, more comfortable, and tougher.
- A conventional insole typically comes with an airbag therein to absorb impacts exerted by the heel. However, the airbag is disposed only at the heel-corresponding portion of the insole and thus fails to soothe the human foot completely, because of non-uniform distribution of pressure on the human foot in the course of foot treading.
- In addition to non-uniform distribution of pressure on the human foot in the course of foot treading, the conventional airbag-equipped insole fails to give sufficient protection to the human foot because of variations in the shoe wearer's posture, center of gravity, and shape of the foot.
- When designed to be full-foot sized, the conventional airbag-equipped insole bends to the detriment of its service life while the shoe wearer is walking or running. Furthermore, the conventional full-foot, airbag-equipped insole has a larger surface area, thereby incurring high production costs.
- Therefore, it is important to provide an insole equipped with an airbag and characterized in that: a gas flows well within the airbag to give sufficient support, render walking or running smooth, and give comfort to the foot, while the shoe wearer is walking or running; the insole makes lengthy standing less tiring; the insole has a long service life; and the sole incurs low production costs.
- In view of the aforesaid drawbacks of the prior art, it is an objective of the present invention to provide an insole equipped with an airbag and characterized in that: a gas flows well within the airbag to give sufficient support, render walking or running smooth, and give comfort to the foot, while the shoe wearer is walking or running; the insole makes lengthy standing less tiring; the insole has a long service life; and the sole incurs low production costs.
- In order to achieve the above and other objectives, the present invention provides an insole, comprising: a hooked pad comprising an upper layer and a lower layer, wherein the upper layer and the lower layer meet and define a closed space for containing a gas which flows therein, and the hooked pad is defined and divided into a bottom portion, a long end portion, and a short end portion, with the bottom portion being connected to the long end portion and the short end portion, the bottom portion corresponding in position to a heel, the long end portion corresponding in position to a medial longitudinal arch, and the short end portion corresponding in position to a lateral longitudinal arch.
- In an embodiment of the present invention, the insole further comprises a lining disposed in the hooked pad.
- In an embodiment of the insole of the present invention, the lining is made of memory foam.

pad 10 comprises anupper layer 101 and alower layer 102. Theupper layer 101 and thelower layer 102 meet and define a closed space for containing a gas. The gas flows within thehooked pad 10 so that the closed space and the gas together function as an airbag. - Referring to
FIG. 2 , there is shown a schematic view of theinsole 1 corresponding in position to a human foot according to the present invention. As shown inFIG. 1 andFIG. 2 , the hookedpad 10 is defined and divided into abottom portion 103, along end portion 105, and ashort end portion 104 which correspond in position to different parts of afoot 2, respectively. Thebottom portion 103 is connected to thelong end portion 105 and theshort end portion 104. Thebottom portion 103 corresponds in position to the heel of thefoot 2. Thelong end portion 105 corresponds in position to the medial longitudinal arch of thefoot 2. Theshort end portion 104 corresponds in position to the lateral longitudinal arch of thefoot 2. In a preferred embodiment, the long end portion is crescent-shaped and thus corresponds in shape to the medial longitudinal arch. In a preferred embodiment, thebottom portion 103 is thicker than theshort end portion 104, because the heel bears the body weight of the shoe wearer more than the lateral longitudinal arch. - Referring to
FIG. 1 , in a preferred embodiment, the hookedpad 10 comprises therein alining 11. Thelining 11 is disposed between theupper layer 101 and thelower layer 102 and corresponds in shape to theupper layer 101. In a preferred embodiment, thelining 11 is made of memory foam and thus the gas flowing within the closed space of the hookedpad 10 functions as a buffer while foot treading is underway. - In a preferred embodiment, the
insole 1 further comprises ananti-skid plate 20. Theanti-skid plate 20 prevents thebottom portion 103,long end portion 105 andshort end portion 104 from skidding; hence, due to theinsole 1, it is feasible for thebottom portion 103,long end portion 105 andshort end portion 104 to correspond in position to specific parts of the foot, respectively. For example, thebottom portion 103 corresponds in position to the heel, thelong end portion 105 corresponds in position to the medial longitudinal arch, and theshort end portion 104 corresponds in position to the lateral longitudinal arch. Referring toFIG. 1 , theanti-skid plate 20 is disposed at a pit of the hookedpad 10 and joined with thelower layer 101 to connect thebottom portion 103,short end portion 104, andlong end portion 105. In a preferred embodiment, theanti-skid plate 20 extends from the top of theshort end portion 104 to the middle of thelong end portion 105 and fills the pit of the hookedpad 10 to the full, so as to prevent thebottom portion 103,long end portion 105 andshort end portion 104 from being wrongly aligned as a result of sliding. To enhance the ease of manufacturing, theanti-skid plate 20 and thelower layer 101 are formed integrally. - Referring to
FIG. 3 , there is shown a schematic view of theinsole 1 according to an embodiment of the present invention. Theinsole 1 shown inFIG. 3 further comprises atransverse arch pad 30 which is teardrop-shaped, but the present invention is not limited thereto. Thetransverse arch pad 30 and thelong end portion 105 are formed integrally. Thetransverse arch pad 30 is deemed an extension to thelong end portion 105. In a preferred embodiment, thelining 11 extends into thetransverse arch pad 30. Therefore, the transverse arch of thefoot 2 is well supported to enable the shoe wearer to walk easily, walk comfortably, and stand comfortably. -
FIG. 4 is a schematic view of how theinsole 1 operates according to the present invention when the heel of the human foot is in contact with the ground.FIG. 5 is a schematic view of how theinsole 1 operates according to the present invention when the heel of the human foot is not in contact with the ground. Referring toFIG. 2 , theinsole 1 is disposed in ashoe 3. Thebottom portion 103 corresponds in position to the heel, thelong end portion 105 corresponds in position to the medial longitudinal arch, and theshort end portion 104 corresponds in position to the lateral longitudinal arch. Referring toFIG. 4 , when the shoe wearer's heels are each in contact with the ground (for example, when the shoe wearer is standing on the ground), the heels bear most of the body weight of the shoe wearer; In particular, the gas at thebottom portion 103 bears the brunt of the body weight of the shoe wearer and thus moves to thelong end portion 105 and theshort end portion 104, leaving thebottom portion 103 almost flat, rendering thelong end portion 105 and theshort end portion 104 full, thereby supporting the medial longitudinal arch and the lateral longitudinal arch. Being full, thelong end portion 105 enables the shoe wearer to walk smoothly. - Referring to
FIG. 5 , when the shoe wearer walks (alternating between heel lowering and heel lifting), the point of application of force exerted by thefoot 2 switches from the heel to the toes via the sole. As soon as the point of application of force exerted by thefoot 2 reaches the sole, the gas positioned proximate to thelong end portion 105 stops as a result of the force exerted on the sole and thus flows back to thebottom portion 103 and theshort end portion 104 to not only flatten the front end of thelong end portion 105 but also render thebottom portion 103 and theshort end portion 104 full. As soon as the point of application of force exerted by thefoot 2 reaches the toes, the gas positioned proximate to thebottom portion 103 and theshort end portion 104 returns to the front end of thelong end portion 105 so that the gas positioned proximate to thebottom portion 103,short end portion 104 andlong end portion 105 store its initial state (unused). Hence, the gas flows within the closed space defined by thebottom portion 103,short end portion 104 andlong end portion 105 and thereby gives full support to thefoot 2 while the shoe wearer is walking or running. - Referring to
FIG. 3 , the insole of the present invention is characterized in that the gas flows within the closed space defined by thebottom portion 103,short end portion 104,long end portion 105 and the transversearch pad 30 and thereby gives support to specific portions of the foot 2 (such as the heel, the medial longitudinal arch, the lateral longitudinal arch and the transverse arch) in different stages, respectively. - Due to its special structure, the insole of the present invention provides sufficient support, renders walking or running smooth, gives comfort to the foot, makes lengthy standing less tiring, has a long service life, and incurs low production costs.
