Description

Shoe cushion

The present invention relates to a cushion body for inserting into the inner bottom of the shoe, in particular, a cushion which can avoid the pain caused by walking the shoes and make the wearing more comfortable.

When walking, one foot will bear 0.8 to 1.2 times of the weight, and the reaction force will naturally be ignored. Especially the reaction force directly impacts the sole, knee and spine of the foot, so it is best to absorb it in the shoe by means of the mat. Impact, otherwise long-term, will cause many foot lesions.

The traditional leather flat shoe cushion is simply a function of providing a cushion in the shoe, and has a poor effect of absorbing vibration and impact. The colloidal insole cushion disclosed in US 7,140,126 is a recent choice to improve the problem of the cushion in the conventional flat shoe, which can be placed in a shoe at will, utilizing the elasticity of the gel material (for example, silicone). With softness, it provides shock and impact when absorbing body movements.

However, since the sole portion of the human foot near the middle is soft and the shape is slightly recessed upward, even when the above-mentioned colloidal cushion provides a soft touch when the sole is walking, the foot portion and the cushion are also used. There is a gap between the surfaces and the foot is not fully supported and cushioned, so it is easy to feel tired and pain after walking for a long time.

On the other hand, when the human body walks, it mainly uses the toe and the front end of the sole to apply force to the ground to push the body forward before lifting the foot, and the neck of the toe (front end and root) The space between the parts also has a structure that is slightly recessed upwards. Therefore, when the toes exert a force on the ground, the toes can not be fully supported and cushioned because there is a gap between the toe neck and the insole or the cushion surface. As a result, the toes also have the problem of being tired and painful after a long walk.

The purpose of the present invention is to provide a cushion which is placed on the bottom of the shoe and allows the user to feel more comfortable and reduce walking fatigue and pain when the user walks, providing functions such as absorbing vibration, cushioning, and massage to the landing foot.

Another object of the present invention is to provide a function of being able to feel more comfortable, reduce walking fatigue and pain, and to generate a feeling of absorbing vibration, cushioning, massage, etc., when the user puts on the bottom of the shoe. A better cushion for elastic propulsion.

The present invention is characterized in that the integral molding of the soft elastic material comprises a base body, and a toe support portion and a sole support portion protruding from the upper surface of the base body, the toe support portion having a crescent shape and having a specific thickness and arrangement The sole support portion is a convex curved surface and has a specific thickness, and has a specific distance between the toe support portion and the sole support portion; thereby, the cushion pad can be worn when placed in the shoe. The toe neck and sole provide more ergonomic support and feel more comfortable.

The technical means of the creation can be ThermoPlastic Rubber (TPR), Thermoplastic Elastomer (TPE), Thermoplastic polyurethanes (TPU), Silicone, and microcell polymerization. As the soft elastic material, Poron, Polyurethane (PU), Rubber Foam (EVA), Sponge (SPONGE), Rubber (RUBBER), etc. The cushion formed by the soft elastic material includes a base body corresponding to a partial shape of a bottom surface of the inner surface of the shoe, and a toe support portion and a sole support portion protruding from the upper surface of the base body, wherein the toe support portion is a crescent shape The two ends of the toe support portion are gradually increased in thickness toward the center to form an inclined curved surface, and the center is the highest point of the toe support portion, and the distance from the highest point of the toe support portion to the upper surface of the base body is 5 mm. ~9mm; the upper surface of the sole support portion is a curved surface, and the distance from the highest point of the curved surface to the upper surface of the base body is 1 mm to 6 mm.

Since the arrangement of the human toes has an angle with respect to the line between the front and the back of the sole, the neck of each toe can be most comfortably supported on the toe support in order to allow the user to wear the shoes. Providing the toe support portion at an angle with respect to the central axis of the base body on the base body; the angle is the angle between the crescent-shaped radius line of the toe support portion and the central axis of the base body, and the angle is optimal. The range is 4o~9o. The central axis refers to a virtual straight line between the centers of both ends in the longitudinal direction of the base body; the radius line refers to the virtual center of the crescent shape of the toe support portion to the center of the crescent moon shape Virtual straight line.

In order to allow the user to feel the most comfortable feeling when the shoes are worn, the toes and the soles of the soles have the minimum distance between the contour edge of the toe support and the sole support (that is, the toe support and the sole support are mutually The closest distance to face is set to 31.8mm~35mm. According to the experimental results, under the condition of this size, the user's foot can be supported by the toe support and the sole of the foot after the foot is inserted into the shoe. On the support.

In the present invention, a surface material may be applied to the upper surface of the cushion so that the surface covers the base, the toe support and the sole support.
