Description
Technical field
The present invention relates to bicycle art, particularly saddle device.
Background technology
Bicycle is as one of the mankind great invention, and a kind of transcendent's power machinery, the vehicle, the especially successful example of Human-computer Interactive Design, exceeded from invention two century-old, be dispersed throughout all over the world, as environmental protection easily the vehicle be used for transport, ride instead of walk; Increasing people carries out as body building ride body-building and leisure; One of sporting events as the fashionable world are very popular especially.
Bicycle adopts manpower self-powered mode, and stepping on has an effect realizes driving to need cyclist alternately to pedal by leg power, like this to the saddle of bracketing health on bicycle, just must meet: ensure the thigh mobility under sitting posture.
At present, extensively adopt the saddle of triangle seat width, it is made up of long narrow front portion and gradually wide rear portion, and its long narrow anterior barrier between two legs, and supports holder perineum part, and inboard portion, corbel portion is supported at gradually wide rear portion.The essence of triangle seat width is exactly cut out the seat surface except hindering thigh activity, be also exactly cut out except after seat surface outside whole thigh place and connected buttocks more than seat width pattern.
Although triangle seat width saddle meets requirement: ensure the thigh mobility under sitting posture.But unexpected bringing allows people deeply by pain under the hip of its hardship thus.Because, flat seat is in daily life example, the seat surface of full width supports whole buttocks and connected leg portion, by Area of bearing is large, pressure is little like this, and due to buttocks and thigh have generous muscle, dense fat, compared with thick skin and relative less nerve fiber, thus to pressure and impact bearing degree high.When buttocks and thigh are all supported, also can produce one and to hover effect, make perineum part hanging seat surface and exempt from the hardship of extrusion.Simultaneously thigh more can by own locomitivity, easily, quick, effectively, play the ability maintaining balance single-handedly.It can thus be appreciated that thigh has crucial and irreplaceable effect in sitting posture.
But for ensureing the thigh mobility of saddle under sitting posture; and adopt triangle seat width saddle----cut out except after seat surface outside whole thigh place and connected buttocks; directly cause by inside support zone only remaining buttocks; lose the perineum part of the effect protection that hovers, significantly reduced by Area of bearing like this and pressure increases.Because this support zone of buttocks is positioned at bun, add that body can be bowed before nature when riding, these all can cause crotch to produce less desirable leaning forward and the trend glided, for stoping this trend can support in body front portion with regard to needs, being now positioned at the anterior position supported of body and only having perineum part.
Be limited to congenital, perineum part is different from the physiological make-up of buttocks and thigh, because of its gather abundant nerve and vascular tissue and tender and lovely sensitivity very, and the unsuitable and not External Force Acting such as withstanding compression and collision.But now should shielded perineum part; but extruding must be born, but also the non-cushioned impact of milli that must bring in the face of middle road bump of riding, inevitably cause its neural shouting pain, local swelling; produce and variously physiologically do not accommodate illness, become the source of misery therefrom.
Double long-time, that road surface is rugged misery especially of riding, so that sway the emotion and play, illness increases the weight of more may bring long-term impact, has hearsay, so can cause male sexual dysfunction for a long time, more very the dire consequences such as cancer.
For this reason, people also did many effort and trial, want to alleviate so that avoid this like the shadow following the person hip under pain, such as: adopt more soft seat surface material, or the seat surface of hollow out perineum part, or both together adopt, intention alleviates the extruding of perineum part, because whole stressed general layout does not change, perineum part is inevitably supported and continues to be extruded, and therefore effect slightly.
More there is the whole saddle dismissing extruding perineum part anterior, it is desirable to once and for all to deal with problems.But problem is come therefrom, first stop crotch to lean forward and the trend glided without saddle front portion, for making up this disappearance, particularly both hands and double-legged strength stop to need whole body, this not only needs to continue to consume a large amount of muscle power, and can have influence on manipulation.The more seriously front portion of barrier between two legs, also has constraint crotch to wave the effect of stable health, after having lacked effect of contraction, greatly increases cyclist and is got rid of danger by unexpected, therefore bring very serious potential safety hazard.
Above method or cure the symptoms, not the disease, or attend to one thing and lose sight of another, more derive serious problems.
Summary of the invention
The object of this invention is to provide a kind of Novel bicycle saddle device, be applicable to cycle racing characteristic, effectively play function of human body, avoid perineum part to be squeezed pain, realize the comfortable and result of use of health of body sense.
Originally radically reform from when tracing back for the pain eradicated under hip; be not difficult to find that the source of misery is at perineum part, the misery causing perineum part comes from and is squeezed, and perineum part is squeezed and comes from protective effect disappearance; protective effect disappears and comes from thigh and lose support, and thigh loses support and comes from seat surface and cut out and remove.Be not difficult to find out thus, simple method of cutting out except seat surface, has the fraud of trimming the feet to fit the shoes in fact.
Action when observation is ridden, cyclist two leg is alternately pedaled to step on and is had an effect, and drives a pair anti-phase conjuncted crank throw to rotate in turn.What wherein thigh hocketed forward direction with hip joint for movable axle center swings up and down action, and maintains anti-phase relation between the thigh wobbling action of left and right.
