Description

A kind of bikini folding bicycle seat

Technical field

The present invention relates to and relate to a kind of outdoor exercises type bike saddle, especially at the structure of its innovation.

Background technology

At present, known outdoor exercises type bike saddle is all integral type, vehicle seat planar design is a triangle saddle, its bottom base is generally with the manufacture of ABS engineering plastics, pedestal covers the flexible polyurethane foam (artificial sponge) of one deck or silica gel, outside face leather or artificial leather parcel, pedestal is supported by spring steel guide frame, relies on a steel pipe to be connected with bicycle rack with a secondary fastener.People ride and use this vehicle seat to there is no uncomfortable sensation the short time, but ride for a long time and people will be made to feel ischium and pubis generation pain, very uncomfortable, especially the front portion of integrated vehicle seat makes the prostate of man be oppressed, blood flow is obstructed, perineum place then feels numb, and urine all feels difficulty sometimes, therefore frequently must stand with one foot to the knee on tread plate, lift buttocks with compressing and the pain of releiving, this just greatly have impact on riding speed and mind.Nearest market there is a kind of frontless vehicle seat, (so-called without nose vehicle seat) its similar roundlet stool, alleviate the hard pressed phenomenon of man's prostate, but owing to lacking vehicle seat front portion, user can lack sense of direction when leg is exerted oneself, sit unstable, feel the trend having downslide.

Summary of the invention

For above-mentioned defect and deficiency, the present invention, according to a kind of bikini folding bicycle seat of human engineering, kinematics and machine manufacture principle design, efficiently solves these problems.

The technical solution adopted in the present invention is: the base material of vehicle seat adopts the manufacture of ABS hard plastics, pedestal covers the flexible polyurethane foam of one deck, outside face leather or artificial leather parcel, it is by a folding front seat cushion of long wooden dipper shape and two circular left sides, right seat cushion is formed, notch shape is made in described folding front seat cushion rear end, rely on below it two V-arrangement springs and by a secondary two-thread screw, nut is hinged on a ratchet base, wearing a pin rod in the spiral coil of two described V-arrangement spring interludes is arranged in the spring clip slot in the rebasing portion of front stall, the upper g. slice header of V-arrangement spring is fixed in the jack of rear end, front stall rebasing portion, lower g. slice header is welded on the wheel hub of a single ratchet, described single ratchet is by a set of two-thread screw, nut is installed in a ratchet base and also can rotates, described ratchet base is fixed on the front end above one piece of spring steel plate, the rear of this ratchet base is separately fixed wtih a gib head seat, a ball handle is arranged on therebetween and relies on a bearing pin to be through in gib head seat, this ball handle can swing up and down around bearing pin, described ball handle front end is a L shape gib head, it is compressed by the torque spring that is enclosed within bearing pin and hooks single ratchet and makes front seat cushion maintenance level, when pressing ball handle, described L shape gib head is just lifted and discharges single ratchet and front seat cushion is forwards naturally drooped, described two circular left, right seat cushion symmetry splits on rear side of front seat cushion axis, their elevation profile profile is low above, high below, centre is depressed part, projection below them assembles respectively a steel respectively to use in flakes bolt and compression spring sheet fastened, compression spring sheet is withheld and is made it fixing in the upper end of two pressure springs, described two pieces steel is middle in flakes makes two circular left sides with a rivet pin hinge connection, right seat cushion can along with fluctuation under the effect of external force, the lower end of two described pressure springs is respectively withheld with a lower making leaf spring and respectively by another secondary bolt, nut and pad are fixed on spring steel plate, below described spring steel plate, inclined weld a round steel pipe and is connected with the steel pipe frame of bicycle by fastener.

The invention has the beneficial effects as follows: medial recess and a left side of leaning forward, right seat cushion cosily can bear the pressure of buttocks and decompose the weight of part human body, when middle leg of riding is exerted oneself, their energy left and right are along with fluctuation, cushion the application force of ischium and seat cushion, alleviate the pain of sitting, and folding front seat cushion can press ball handle in riding after to front hanging down, and its rear end is made notch shape and is effectively avoided seat cushion to pubis and the prostatic extruding of man, can make it again when plate plays front seat cushion to become horizontal, recover traditional use habit, it manufactures simple, use reliable and stable, change the structure of known bike saddle.
