Abstract

The utility model relates to a shoe sole, and particularly an elastic spring shoe sole. The interior of the shoe sole is provided with a concave hole in which the spring in arranged. The utility model provides a shoe sole which has a structure which can store and release energy. The consumption of internal energy when people walk can be reduced. Simultaneously, the reaction force of the ground to human body and fatigue can be reduced. The utility model has the advantages of human body protection, labour saving, boosting and comfort.

Description

The elastic spring sole

The utility model relates to a kind of sole, particularly a kind of elastic spring sole.

For many years, the footwear of market sale, its sole are considered human motion energy storage and are released can ability the time, most elastic plastics characteristics that rely on material for sole of shoe self, act on little, consume during the walking of old friend's body interior can be bigger, feel fatigue easily.

The purpose of this utility model provides a kind of elastic spring sole that has energy storage, releases the energy structure.

The purpose of this utility model realizes in the following manner: a kind of elastic spring sole, be provided with shrinkage pool (2) in the sole (1), be provided with spring (3) in the shrinkage pool (2), spring (3) upper end is fixed in the sole (1) or on the metallic plate (4), metallic plate (4) is located in sole (1) body, toe cap, heel portion spring (3) expose, and middle part spring (3) exposes or is enclosed in the sole (1), are provided with rubber slab (5) below the sole (1).

Compare with the sole that uses now, the spring sole has stored energy, the function that releases energy, drum has the following advantages: the spring sole elasticity is good, be out of shape by the body weight for humans force compresses, when recovering distortion, deformation potential produces a bullet thrust that makes progress to sole, thereby can make human body economize in the part and can consume in the walking time, simultaneously, can alleviate the degree of fatigue of muscle ligament in the face of the reaction of human body again with slowing down.The utlity model has protection human body, laborsaving, afterburning, comfortable effect.

Describe the utility model embodiment in detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation.

Fig. 2 is the sheet metal structure schematic diagram.

The utility model footwear body can be made from a variety of materials, as skin, rubber, plastics, polymeric material etc., but casting forming.Be provided with shrinkage pool (2) in the toe cap of sole (1), middle part, the heel, spring (3) is housed in the shrinkage pool (2), spring (3) is C template spring or screw type wind spring, the position of the quantity of spring (3) and each spring (3) touchdown point is all by stressed supporting-point design, or a plurality of springs (3) are evenly arranged, spring (3) is divided into 15 feather weight, 20 feather weight, and so class is pushed into 150 feather weight.Heel spring (3) has the branch of 30～150 feather weight, is C template spring, and 2 of the rivet holes of φ 2～φ 4 are arranged on it, and 2 of the nut bore of M4～M6 are arranged down, and it is different and different that length is looked the footwear specification, and gradient is about 15 ° below the heel.Footwear medi-spring (3) has the branch of 15～75kg weight category, be C template spring, be used for footwear half sole place and have 2, the feather weight sum should equal or be slightly larger than heel spring kilogram number, the middle part is 3 springs (3), the feather weight sum should equal or be slightly larger than heel spring kilogram number, and the hole is with heel spring (3) up and down, and specification is multiple.Toe cap spring (3) has the branch of 30～150 feather weight, is C template spring, and the hole is with heel spring (3) up and down, and the hole is each 2 up and down, and it is different and different that length is looked the footwear specification, and gradient is about 12 ° below the toe cap.Various soles such as walking shoes, middle high-heeled shoes all can add spring (3), the sole of other shapes also can add spring (3), and can add one, two rows, each is arranged quantity and also can reduce or increase, heel, toe cap C template spring are better, when effect must be not strong, also available screw type wind spring etc., the spring in the footwear (3) also can be with the screw type wind springs etc.Spring (3) upper end riveting is in sole shrinkage pool (2) upper end, or the spring riveting is on metallic plate (4) as shown in Figure 2, metallic plate (4) is a copper sheet, steel disc etc., thickness is 0.5～1.2MM, between metallic plate (4) spring eye reinforced company's tape splicing is arranged, metallic plate (4) is gone up preformed groove from sole (1) and is packed into, fill the preformed groove except that spring position then, sole (1) face sticker rubber plate (5), sole screw (6) head of a nail is sphere or taper seat, maximum φ 5～φ 9, thread segment is M4 or M6, the cap root is processed into square or hexagon, and sole upper surface is provided with vamp plate (7), and vamp plate (7) thickness is 3～5MM.
