Description

Flexible arm hinge speed skate blade

Art

This utility model relates to the structure of a kind of toe curving type bob skate, and especially Neng Shi foot metatarsophalangeal joints does toe in the wrong fortune Dynamic flexible arm hinge speed skate blade.

Background technology

At present, together with old-fashioned speed skate blade is integrally fixed at skating boots, old-fashioned speed skate blade is pedaling skates point of a knife after ice terminates There is stingy ice phenomenon；The most popular KLAP formula speed skate blade, the front and rear of its long-armed hinge and the front end of skating boots and after End is fixed together, and the skates at long-armed hinge rear portion can preferably solve old-fashioned speed with folding with seat and skates between torr Bob skate is pedaled ice and is terminated rear point of a knife produced problem.Domestic in succession have developed toe curving type bob skate, although speed skate is changed Become toe curving type skating boots, again without " in-line " fixed form broken away from before and after speed skate.Owing to old-fashioned speed skate blade is being pedaled At the end of ice, point of a knife has the phenomenon of stingy ice, KLAP formula speed skate blade to be to be transferred to tiptoe by full foot to pedal ice when pedaling ice, the most existing The ultimate principle of human foot's normal physiological motion run counter to by skates.

Summary of the invention

Solve the technical problem that

Running counter to human foot's proper motion physiological problem to solve existing speed skate blade, this utility model provides one Flexible arm hinge speed skate blade, it can grow after making with torr and skates with free-open-close between seat, moreover it is possible to along with foot bend toe motion and Change.

Technical scheme

This utility model solves its technical problem and be the technical scheme is that and adopt between skates hinge and skates are with seat Connecing composition flexible arm hinge by the soft bridging of steel disc, when human foot makees to bend toe motion, the soft bridge of steel disc can deform upon.In joint rocker Have two aerofoil screws on face, and skates with seat on have with seat elongated hole, form " triangle " 3 point of toe curving type skate Fixed form, makes toe curving type skate fixing-stable, can also reach the purpose that skating boots can bend.

Beneficial effect

The beneficial effects of the utility model it is possible to make foot's metatarsophalangeal joints do toe in the wrong motion, is conducive to improving speed sliding Ice pedal ice efficiency and the sports achievement of ski-running project, toe curving type skate are more firm with the three-point mount of " triangle ", Be conducive to the bending of skating boots, reasonable in design and simple in construction.
