Description

Pedal accessory for bicycle

The utility model relates to the pedal that ordinary bicycle and three-wheel vehicle are used.

Existing common pedal can only be accepted the strength that pin is stepped on downwards as the part of accepting of human body power, plays forward and does not use the strength youngster, and it is more impossible upwards to carry.This stiff force method has determined existing pedal to do work in the angular range in about 1/4 week, more difficult near last lower dead point, not only horsepower output is low, and easily produce tired because of the muscle that shrinks acting and the joint part of exerting oneself are too fixing and ache, even cause strain, some unexpectedly match adopted the harness such as bicycle shoes, footmuff, belt, claim-reduction of band clamp on bicycle." making the connection cycling shoes that is used for racing car and the device of stretcher especially " proposed in Chinese invention patent 85102075.On the treadmill tool, adopted velcro that pin is bundled on the pedal.These harness have been arranged, make pedal except the following legpower of accepting pin, also can accept pin before play power and upper lifting force, improving horsepower output, utilize the motor function of lower limb more fully, alleviate the local fatigue in muscle and joint and the aspect of aching has played certain effect, but the common issue with that exists is an operating conditions with operating conditions not to be stretched into promptly with the conversion of withdrawing from or being connected and throwing off and all need use manual manipulation.Preceding two kinds also need special bicycle shoes, not only inconvenient, and ordinary bicycle and the three-wheel driver upright substantially to upper body, and it is very difficult riding over and reaching the pedal operation with hand on the saddle, and very dangerous.After pin left pedal, the harness meeting of cover pin had increased the trouble that reuses because of forwarding the below to from recoiling the pedal axle.So these harness are difficult to be widely accepted to the ordinary people who rides ordinary bicycle.

The purpose of this utility model is to address the above problem, make common pedal when can accepting the following legpower of cyclist's pin, also can accept pin before play power and upper lifting force, and its operating conditions helps with the nation that the conversion of operating conditions not need not hand, list can be finished with the simple motion that puts in or withdraw from of pin, and the ordinary people also can be used on safe ready ground when riding ordinary bicycle and three-wheel vehicle.

Task of the present utility model is finished as follows:

In the one side of ordinary bicycle pedal counterweight in addition, the fastening similar horseshoe-shaped broadband cover (can abbreviate the broadband cover as) with certain rigidity and intensity of another side can just entangle the instep of wearing the cyclist of city shoe.Because counterweight is arranged, this broadband cover can remain on the top of pedal, and because of its preceding marginal pore is little, trailing edge holes is big, has certain rigidity and intensity again, so the help pin without hand just can put in and withdraw from, and broadband cover can pass to pedal and bent plate with playing power and upper lifting force before the pin, around the axis acting, sometimes at pin when the broadband cover is stretched, can meet its edge and pedal is bumped commentaries on classics forward, inconvenience is stretched into.Stretch out a steady ring backward from pedal, its position just in time is in pedal in case change forward, will run into cyclist's sole, and can not change for this reason.Counterweight special and that steady ring balances each other is also arranged on the pedal.As long as tiptoe is between the trailing edge holes and steady ring of broadband cover like this, when pin stretches into, all can be easy to stretch into.Because run into the trailing edge holes limit of broadband cover, limited by steady ring, pedal can not change forward, steps on steady ring, and then pedal can turn round, and helps pin and stretches into the broadband cover and turn round.The size in the hole that forms as for broadband cover and the matching problem of pin, in the time of can be with each use, the problem that stretches into withdraw from of pin be separated and is solved.Solve previous problem and can use manual manipulation, reconcile hole size to adapt to the size variation of pin.Method is that conversion broadband cover carries out coarse adjustment in the position of screw hole when being fixed on the pedal.Can also finely tune with the method that changes the pad number of plies.Because the cyclist generally fixes, the size of pin seldom changes.General only because of change season, the size of broadband trepanning needs to change with footgear thickness.So must reconcile the situation of the size of broadband trepanning, possible some months just runs into once, just address this problem with manual manipulation and can not feel inconvenience.

Embodiment below in conjunction with accompanying drawing provides elaborates to the utility model.

Fig. 1 is after the utility model is installed on the common pedal, the full section scheme drawing of doing along the plane vertical with the pedal axle.

Fig. 2 is after the utility model is installed on the common pedal, from the back eyes front promptly the figure A to view.

Fig. 3 is that the utility model is installed in birds-eye view later on the common pedal.

Utilization have enduring of certain rigidity and intensity the frivolous material of living, for example: plastics, glass-felt plastic, thin metal skin, thin aluminum sheet preferably, make similar horseshoe-shaped broadband cover (1), its width is greater than general footwear belt, strap or nylon tape, be wide 3-7 centimetre, its degree of dip is worn the shape decision of instep behind the footwear by the people.The broadband has put several holes (2), utilizes drift bolt (6) and nut (11) on the pedal to be fixed on the pedal.Unnecessary hole is used for degree of tightness and reconciles usefulness, is adjusted to water chestnut hole size that the broadband cover forms and cyclist and wears that the size of instep adapts behind the footwear.Because the preceding marginal pore in the water chestnut hole of matching with pin is little, trailing edge holes is big, so pin not only can above drawings power do work, also can play firmly acting in the past, certainly do not influence yet and step on acting under original, and just can put in pin in the water chestnut hole, or therefrom withdraw from without the help of hand.Because have enduring of certain rigidity the material of the living broadband of making overlap not the elephant hide band or nylon such, pedal is withdrawn from the distortion of will flatly collapsing.

The broadband puts the hole (3) of two strip shapes in addition, in order to abdicate the two ends of pedal axle.The another side of pedal has two iron plates, thick 1-5 millimeter, and its size is suitable with pedal.Wherein an iron plate is parallels (8), and another piece is pressing plate (9), and both have bending slightly in the part near pedal axle two ends, when making the unnecessary broadband cover (5) that is sandwiched between the two walk around, and the unlikely dog leg that occurs.At unnecessary broadband cover (5), all have on parallels (8) and the pressing plate (9) corresponding hole several so that allow two U-shaped thru-bolts (4) that are enclosed within on the pedal central siphon (15) pass, tighten with nut (10) from these holes.This hole should have more than neededly on parallels and the pressing plate, and in order to reconciling water chestnut hole size usefulness, its pitch-row should to put the pitch-row in hole (2) identical with the broadband.Pressing plate and parallels play counterweight simultaneously, make the weight of this face be far longer than the weight of shape of a hoof broadband cover one side, thereby make shape of a hoof broadband cover can remain on the top of pedal axle, big convenience use.

When pin stretches into the broadband cover, unavoidably pedal is bumped commentaries on classics inconvenience and stretch into.For head it off accompanies steady ring (7) below footstep leather and between the parallels, stretch out on one side footstep leather 2-6 centimetre of water chestnut hole trailing edge macropore, K/UP is to flat with the upper surface of pedal.For and steady ring (7) this part balanced of stretching out footstep leather water chestnut leading edge opening aperture on one side the footstep leather lower surface and parallels between accompany steady ring counterweight (14).Steady ring (7) is run into cyclist's sole, and pedal can not change forward, can only be stepped on to turn round, and then helps pin and stretches into the broadband cover.

At part cushioning one circle thin skin leather or the fabric that shape of a hoof broadband cover (1) contacts with instep, make foreskin (12) and connect with snap-fastener or velcro (not marking among the figure) at two of foreskin (12).Between the lower surface of foreskin (12) and broadband cover (1), fill up with the laminates sheet (13) of walking around the convertible number of plies of overlapping in the broadband and can finely tune the water chestnut hole size that the broadband cover forms by the number of plies that changes cloth sheet (13), with the subtle change of the size that adapts to cyclist's pin of wearing footgear, usually can save the trouble of dismounting drift bolt (6).Laminates sheet (13) plays a part also to prevent that cover edge, broadband from galling foreskin or footgear.The effect of the then existing fixed cloth strip of foreskin (12) (13) each and anti-attrition footgear has decoration function again.

The utility model is compared with existing ordinary bicycle pedal, because shape of a hoof broadband cover (1) has been arranged, play power and upper lifting force before the instep and can pass to pedal and crank by the broadband cover, become around the torque of axis and do work, and don't impact, legpower acting under original sole. But all application of force actings of sole and instep, improved the effect in power output of ankle-joint and hip joint, alleviated kneed burden, make the front muscle group of the shank that sticks up pin and after carry shank biceps muscle of thigh and on carry thigh muscle group etc. these when using common pedal, do not participate in the muscle group that drives acting directly, can participate in directly and drive acting, thereby alleviated the lower quadriceps muscle of thigh of acting, the burden of gastrocnemius and gluteus maximus etc. of stepping on of pipe. The arrival that has slowed down local fatigue and ached, and improved cyclist's power output, effectively the acting angular range can reach for 3/4 week, can effectively overcome the dead point, be specially adapted to long-distance riding, acceleration, upward slope, three-wheel are hauled goods, the old man rides the body-building etc. of riding instead of walk of little three-wheel, and can resemble some contest need wear extraordinary bicycle footwear with bicycle, and each the use wanted hand operated. These are upright to upper body, and hand is to be difficult to accomplish apart from pedal ordinary bicycle hand far away, and not enough safe requirement. Use the utility model, because counterweight has been arranged, shape of a hoof broadband cover and the locating ring that can keep definite shape have been arranged, use a simple motion that all only needs pin to put in or withdraw to finish the work attitude and the not conversion of operating conditions at every turn.
