Description
Technical field
The present invention relates to a kind of footwear, be specifically related to a kind of amphibian frog footwear, can use when diving, again can at land walking.
Background technology
Frog footwear are the important equipments that people use in skin-diving, it allows swimming fan realize obtaining more effective motive force in water by playing of lower limb, and general frog footwear are by footmuff (being used for fixing frog footwear on diver's foot) and web water half sole (providing diver's propulsive force in water) two parts composition；The footmuff of traditional frog footwear and web water half sole are an inseparable entirety, and the bottom surface of footmuff and web water half sole is in same level, are adopt rubber once injection moulding.The frog footwear of this structure are in same level due to the bottom surface of footmuff and web water half sole, product purpose is single, can only be adapted in water and use, body idle (such as at land walking etc.) cannot obtain reasonable employment, especially as frog footwear entire length is long, it is not easy to trip carry, therefore makes troubles to use.Being additionally, since is adopt rubber once injection moulding wearing feeling bad, easily comes off during pine diving, and tight dress is uncomfortable.
The patent of invention that Chinese Patent Application No. is " 200620066168.3 " discloses a kind of folding dive flipper for diving under water, including a footmuff, one web shape blade extended by footmuff and with footmuff disjunctor, characterized by further comprising a shoe body, penetrate for wearer sole, the symmetrical place at the closely big end, shoe body both sides is fixed with chute, and chute end is provided with card interface；Described footmuff rear end is provided with the cavity matched with above-mentioned shoe body head, inserts fixing for shoe body head, and behind footmuff both sides, end terminal is respectively equipped with pulley, and pulley slips into the chute inner position of shoe body by card interface；One snap fastener strap, activity is fixed on foot body, and snap fastener strap is provided with a clamping close device, is available for fixing with footmuff when footmuff folds.Although this frog footwear are capable of amphibian purpose, but there is the complicated and awkward shortcoming of structure in folding structure.
Summary of the invention
For the deficiencies in the prior art, the invention aims to provide a kind of simple in construction and frog footwear easy to use, namely can use when diving, it is possible at land walking, simultaneously it also there is softness, endurable, antidetonation, anti-skidding and wear comfortable feature.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of frog footwear, it is characterised in that: include the big end being fixedly connected sequentially from the bottom up, the middle end and vamp；
The described shape size at the big end and the shape size of human foot match, and the described big end is the rubber sole adopting rubber to be made；
Said midsole includes the support portion matched with the shape size at the big end, the web water portion of the web shape that the foot palm part edge along support portion extends outward；Said midsole be adopt polyurethane injection moulding integrated molding polyurethane in the end；
Described vamp adopts the sewing of diving suit fabric to form；The support portion of said midsole and vamp form an accommodation chamber for holding the whole foot of human body.
As preferably, said midsole adopts polyurethane one-body molded by continuous-upper injection moulding process, and said midsole links into an integrated entity with vamp and the big end respectively in continuous-upper injection molding process.
As preferably, said midsole also includes the arch extension with opening upwards arched upward along the end face of support portion；A first accommodation chamber for holding toe is formed between inwall and the support portion immediately below arch extension of described arch extension；The edge of opening of described arch extension and edge, support portion enclose formation the first connecting portion；Described vamp includes the second connecting portion for wrapping up sole and heel and for wrapping up the 3rd connecting portion of ankle, first connecting portion at described second connecting portion and the middle end matches, and described second connecting portion and the first connecting portion are fixed connection, formed one for holding the second accommodation chamber of sole and heel；After described second accommodation chamber encloses with the first accommodation chamber, form one for holding the accommodation chamber of the whole foot of human body.
As preferably, the bottom surface at the described big end being provided with some projections.So it is designed to improve the non-skid property at the big end.
As preferably, the bottom edge place at the described big end is provided with some grooves.So it is designed to improve further the non-skid property at the big end.
As preferably, the outer surface of described vamp being additionally provided with elastic cord.So it is designed to regulate the elasticity of vamp according to individual's practical situation so that dress more comfortable.
As preferably, being provided with slide fastener in the side of the 3rd connecting portion of described vamp.So it is designed to be easy to wear off, uses convenient.
As preferably, being provided with lift ring at the back side of the 3rd connecting portion of described vamp.So design is easy to carry.
As preferably, described diving suit fabric, it is commonly called as Neoprene, is specifically as follows neoprene.Described vamp is first diving suit fabric to be cut into some according to shoe-making process, by sewing machine, blocks of diving suit fabric is sewn into vamp, and vamp is carried out to be needed to package with shoe last to shape, thus making the shape of shoes.The shape of shoe last is closely similar with human foot, base plate is the same with human body sole, it is all uneven, PU polyurethane is one-body molded by continuous-upper injection moulding process, so that the base plate that the base plate of the middle end that PU makes also is same shoe last is equally uneven, such shoes wear to compare and fit, and improve comfortableness further.
Compared to existing technology, the beneficial effects of the present invention is:
1, the present invention is provided with the shape size with human foot and matches at the big end, the web water portion of web shape is arranged on middle body, and the middle end, adopts polyurethane one-body molded by Shooting Technique, namely the frog footwear of this structure can use in diving, can directly walk on land again, achieve amphibian function, the advantage with simple in construction, sum easy to use.Further, since the big end is the rubber sole adopting rubber to be made, having that wearability is good, anti-skidding, flexible, not easily split, pliability is better, expandability good, contraction is stable, and hardness is good, good bandability, the advantage of waterproof；The middle end, adopts in polyurethane the end, has that density is low, quality is soft, and elastic good, comfortable and easy to wear, good oxidation resistent susceptibility, excellent anti-wear performance, anti-flex performance, hardness are high；The damping of excellence, non-skid property；Good heat resistance；Good chemical resistance；The what environmental protection of perishable profit, not easily fold.Vamp adopts the sewing of diving suit fabric to form.Therefore, it also there is softness, endurable, antidetonation, anti-skidding and wear comfortable advantage.
2, compared with prior art, in the present invention, the end, links into an integrated entity with vamp and the big end respectively in continuous-upper injection molding process, without chemical materials such as plastering agents, does not therefore produce any chemical contamination, the Nature is nuisanceless, without degumming.Not only conform to International Environmental Protection requirement, and in the utilization of material, also fully demonstrate the environmental consciousness of injection moulded shoes.
3, due to the fact that on the middle end, be provided with arch extension, and between the inwall of arch extension and the support portion immediately below arch extension, form a first accommodation chamber for holding toe, therefore, in the process of walking, the active force of toe is concentrated mainly at middle the end, rather than concentrates on the connecting portion at the middle end and vamp, it is possible to alleviate the infringement to connecting portion, it is prevented effectively from connecting portion cracking, thus extending the service life of shoes.
