Description

The stand-type wheelbarrow of steady pin components is housed

Technical field

The present invention proposes a kind of stand-type wheelbarrow that steady pin components is housed.Or rather, be a kind of, stand-type wheelbarrow that steady pin components be housed that drive with pedal (Pedal).

Background technology

Unicycle is known by the insider, and modal with the pedal driving, with the wheelbarrow at seat, they are widely used for amusement and acrobatics.As the equipment of a kind of amusement and body-building, wheelbarrow is difficult to association and rides." find it difficult to learn " although promoted recreational contest, also reduced " ride " interest of many people simultaneously.

Also have a kind ofly not with the wheelbarrow at seat, before 5 years, just had many products to sell (consulting: the deciphering of dimension base, Wikipedia, the free encyclopedia) on market.Because it does not have vehicle seat, ride more difficult control balance, so everybody generally claims that it is " the ultimate wheel (Ultimate wheel) " or be called " difficult riding wheel (Impossible wheel) ".(sometimes by a kind of without seat, wheelbarrow that stretcher is fixing also referred to as " difficult riding wheel ").Riding does not thisly more need the reason of skill to be with the wheelbarrow at seat than the wheelbarrow that is provided with seat: in the time of by bike, in the process that drives pedal, wheel can be swung to side, causes car to lose the balance of left and right; Do not choose a place to give a banquet the position wheelbarrow, each side of car, cyclist's leg and car only have a contact point, that is the pin that the cyclist steps on pedal is contact point unique between car and people; Only, by a contact point, add that car is again can be free-moving all around, be difficult to make the relative position of cyclist and car, control substantially constantly or basically identical on the direction with vertical ground.So it is extremely difficult wanting to stop wheel to fall down with undesirable angle.Otherwise the cyclist only has the wheel that rubs and do not cover with leg, to the side that stops wheel, fall, so it is more difficult without the wheelbarrow at seat to ride, need more skill.

Therefore, the stand-type wheelbarrow that needs an energy to drive with pedal on market, and there is higher lateral stability, conventional products before being used for substituting, the training device of the wheelbarrow of the more difficult type of riding can be used as, or the wheelbarrow of a new variant can be increased for this field.

Summary of the invention

The objective of the invention is to prepare and a kind ofly than current product, there is upper side to stability, wheelbarrow that can more accurately be controlled by the cyclist.For making car stable, wheelbarrow of the present invention has installed a steady pin components above pedal, and this steady pin components is to stretch towards the top of pedal, on steady pin components, a leg plate is arranged.When cyclist's pin is in place while stepping on pedal, can keep in touch with leg plate all the time in the inboard of cyclist's leg.The cyclist exerts pressure to leg plate with the inboard of leg, can reduce the unnecessary canting occurred in stepping the process of pedal, thereby increased the stability that car is ridden, also increased the efficiency accurately controlled of car when turning, uphill/downhill and rough road are travelled simultaneously.

By analyzing, can find that wheelbarrow is identical with the principle of stilt walk maintenance balance, wheelbarrow and stilted operator are the movements that makes wheel or stilt, and the position of controlling center of gravity by the movement of limbs, thereby keep balance.Here said center of gravity, refer to synthetic center of gravity when whole of operator and car, and the position between operator and car is substantially constant in vertical direction, and the center-of-gravity position of both integral body is also substantially constant.For unicycle, if the position between operator and car is constantly changing, or can not keep in vertical direction basically identical, operator and car center-of-gravity position separately is each comfortable change, synthetic center of gravity when whole of operator and car is also in continuous change, operator and car also just can't keep balance, because the operator is difficult to stand firm on pedal, even be also to be difficult to stably to control car advance for the people who is familiar with controlling skill.

The history that stilt walk is existing very ancient in China.The stilt that moderns are used, have two dividing of lifting up, singly lift up.Twoly lift up many colligations on shank, singly lift up the top of with both hands, respectively holding every stilt.The every limit of which kind of stilt is all that two fixing point of connection are arranged, and two lifting up is that pin is stepped on two point of connection of colligation place on place and shank, singly lifts up that to be the foot place of pedaling locate two point of connection with holding.These two fixing point of connection make operator and stilt blend together one, maintain a common center of gravity on the vertical direction with ground.Therefore, operator and stilt can keep balance, not only can stablize and advance, and can also perform the civil and military stunt of all programs.Between every leg of operator and every stilt, only have a point of connection can not play stilt.After investigating stilted principle, can find to stand in every the pin of unicycle operator on pedal, a point of connection on pedal only, if there are two fixing point of connection, just can make the operator stand firm on pedal, stably control the work that car is advanced or done other.

Therefore, the stand-type wheelbarrow that the present invention proposes is mainly the structure that has changed the unicycle that proposed in the industry in the past, be provided with a steady pin components be connected with car body above pedal, its effect is to make cyclist's leg can be close to car body, pedaling foot sentences on pedal, increased a basic fixing point of connection, after making between every leg of cyclist and car body that two point of connection have been arranged, the cyclist just can stand firm on pedal, has stably controlled car.On each steady pin components, device has leg plate, is used for respectively leaning on mutually for cyclist's two leg contacts, makes both feet in stepping the process of pedal, and two legs can be kept in touch and lean on mutually with leg plate all the time.Thereby, improved the car stability of riding and the particularity of controlling.

Some example of the present invention has proposed to use oval-shaped wheel.As everyone knows, in the cycle of two pedal cycle rotations, two pedals are vertically in line the time, " dead point " of causing the application of force, and wheel is applied to rotating torque difficulty in essence.Use the wheelbarrow of parabolic wheel can overcome this difficulty.

The experience personage is arranged in the industry check describing in detail hereinafter in conjunction with drawing after, can further understand technical characterstic of the present invention and other relevant advantage.

These examples, will describe in detail hereinafter.

The specific embodiment

Consult Fig. 1 and Fig. 2, this is a kind of stand-type wheelbarrow 100 that steady pin components is housed proposed by the invention.Wheelbarrow 100 includes single wheel 110, two pedals 120 and two steady pin components 130.Two pedals 120 are matched with wheel 110 respectively, are used for driving car 100.Steady pin components 130 is matched with pedal 120, is connected to the inboard of each pedal 120.Wheel 110 only has single spoke 111, is connected across on the diameter of wheel.In other examples, the structure of wheel may be slightly different with at present known technology.Two pedals 120 are arranged on respectively the both sides of wheel 110 rotationally, and they can support the cyclist, for the cyclist, stand, and make the cyclist drive wheel 110. with pedal 120.Each steady pin components 130 includes a vertical connecting rod 131, and it normally stretches upwards out from pedal 120.(" direction upwards " used while here steady pin components 130 being described and terms such as " direction are vertical ", be orientation in use for car 100, the orientation of car 100 when Fig. 1 illustrates use.Here the direction of indication refers to the direction of " usually " meaning, is not the direction on " accurately " implication because steady pin components 130 is along with pedal 120 rotations, so in stepping on the process of pedal, cyclist's leg go through slight variation towards meeting).On each vertical links 131, with a leg plate 132, its surface and height and position just in time can support cyclist's leg.So two steady pin components, respectively have one by the leg surface, matched with described pedal assembly separately after, when the cyclist stands on pedal while riding, cyclist's two legs can with by the leg surface, keep in touch.

On the wheelbarrow 100 shown in Fig. 1 and Fig. 2, vertical links 131 is strut bars that connect pedal 120 and leg plate 132; Yet, in other example, the structure of steady pin components 130 is slightly different.For example, vertical links 131 can connect with hinge, can towards the direction of pedal 120 is folding, draw in downwards, (still, can not fold towards wheel direction, because cyclist's leg is towards the interior side direction application of force of leg, so vertical links 131 must keep rigidity for this reason).In addition, vertical links 131 and pedal 120 can be with integrally moulding of commaterial.Perhaps, vertical links 131 and leg plate 132 can be with integrally moulding of commaterial.

Be provided with one on steady pin components by the leg surface, in this example, be leg plate by the leg surface.After cyclist's pin stands on pedal 120, leg is put into to the position of leg plate 132, cyclist's inboard leg is exerted pressure to leg plate 132, with leg plate 132, is close to, and cyclist's leg has obtained support.The cyclist is in the circulation that steps pedal, and two legs all is close to leg plate 132 all the time.Increase to two point of connection between every leg of cyclist and car, therefore increased the stability of car side.With between cyclist's leg and car, only have point of connection of pin and pedal to compare, the cyclist just can control wheelbarrow with comparalive ease.Every leg of cyclist has two point of connection and only has the difference of effect between a point of connection identical with " stilt " with car, is also clearly.As everyone knows, if only have a point of connection can not play " stilt " between every leg of operator and every " stilt ", operator's pin is with beyond the tread plate of " stilt " is connected, the shank position also needs to pinion with the bar that extends upward of " stilt ", after two point of connection have been arranged, just can do various " stilt " performance.But, second point of connection of wheelbarrow, can not bundle fixingly between shank and leg plate 132, in order to ensure safety, allow the cyclist can be at any time without restriction leg and car to be broken away from, and from car, jumps off safely.Obviously, after being provided with leg plate 132, along with the increase of lateral stability, the cyclist can more easily control the direction of car; While travelling on slope or rugged landform, the cyclist can more easily stablize onboard; When riding and when getting on or off the bus, the cyclist can more easily prevent unintentional lateral inclination overturning.Leg plate 132 can be made with a soft a little class material (as: rubber).Leg plate 132 and the leg mating surfaces of car both sides can have the curved surface of depression a little, with cyclist's roughly matching of the inboard contact surface of shank.Steady pin components 130 can arrange to obtain slightly outwards canting, is beneficial to the cyclist and is easy to leg plate 132 is exerted pressure.These performances are all that the shank that is conducive to the cyclist keeps good mechanics to be connected by friction and leg plate 132.

Because the center-of-gravity position after the steady pin components 130 of car both sides and pedal 120 combinations is not near pedal 120 spindle centrals, when cyclist's leg is not yet in place, the steady pin components 130 of car both sides can freely fall down forward or backwards around the spindle central of tread plate 120, can't make to maintain a certain distance between two leg plates 132, so between two steady pin components 130, a connecting band 140 will be set.Connecting band 140 makes two leg plates 132 can not move to exceed certain distance, the steady pin components 130 that makes a side when cyclist's leg is when vertical position, the steady pin components 130 of opposite side also can be in similar position, between two leg plates 132, will remain certain distance.Connecting band 140 can adopt different patterns or different materials, as: elastic bands or the plasticity bar (as shown in Fig. 1, Fig. 2) that softens connects the top at two vertical links 131.

Another makes two leg plates 132 keep method additional weight below each pedal 120 of certain distances, make steady pin components 130 and pedal 120 in conjunction with after center-of-gravity position lower than the spindle central of pedal 120, more near ground.Now, even when cyclist's two legs are not yet in place, steady pin components 130 also tends to vertically on one's feet usually, before and after not understanding, falls down.

As shown in Figures 1 and 2, a plurality of point of connection 121 are arranged on vehicle wheel spoke 111, they are for connecting pedal 120.Two pedals 120 can be selected for the cyclist according to performance and hobby with the spacing at wheel 110 centers.A plurality of point of connection 121 on vehicle wheel spoke 111 be exactly change between two pedals 120 apart from the time point of connection selected.

Fig. 3 has shown the another kind of embodiment that can change distance between two pedals 120.In this example, be provided with a guide rail 122 on spoke 111, make two pedals 120 to slide along the track, can be used to control subtly distance and the position of two connected pedals 120.Guide rail 122 can be also slide rail, and when two pedals 120 are stepping process for what promote car, the distance between two pedals 120 can be arranged to variable configuration.Now, two pedals 120 have been executed bias voltage (by spring or other method), after bias voltage is eliminated, and automatically reinstatement.That is when two pedals 120 are not subject to external force, mutual and wheel 110 center maintains certain distance, when being subject to external force, distance between two pedals 120 can become far away or become nearly (becoming far away or becoming is closely the direction and size that depends on the person for driving a car institute application of force), after external force is cancelled, between two pedals 120, be returned to original distance.As everyone knows, under regular situation, pedal is to be difficult to applied thrust moment when stepping some some position of circulation, due to the set configuration of slide rail 122, it is the distance that can automatically regulate between pedal 120 and wheel 110 centers, therefore this configuration makes the person for driving a car also can easily execute out thrust moment in these some positions, promotes the car operation.As can be seen here, the technical characterstic of this example is: because the pedal 120 on the pedal assembly is rotatably connected on spoke 111, so pedal 120 is connected with wheel rotationally by spoke 111, the axis of each pedal 120 each own rotation, distance between two pivots center of two pedals 120 can be regulated, in other words, the pivot center be rotationally connected between pedal assembly and wheel, and the distance between the pivot center of wheel can be regulated.

Fig. 4 and Fig. 5 have shown another example proposed by the invention, and Fig. 4 is the transparent view of wheelbarrow 200, and Fig. 5 is the lateral plan of wheelbarrow 200.In this example, wheelbarrow 200 is with wheelbarrow 100 differences on Fig. 1, Fig. 2, uses oval-shaped wheel 210 to replace circular wheel 110.Miscellaneous part is all similar, and pedal and stabilization parts are arranged on single spoke 211.When oval-shaped wheel can compensate some some position, wheel is applied the difficulty of moment, particularly difficult when two pedals are on vertical straight line.Equally, wheelbarrow 200 also can arrange slide rail, and its function is also as mentioned above.

Fig. 6 and Fig. 7 have shown another example proposed by the invention, and Fig. 6 is the transparent view of wheelbarrow 300, and Fig. 7 is the lateral plan of wheelbarrow 300.In this example, two of the left and right of wheelbarrow 300 pedal 320 is not directly to connect on spoke 311, and each pedal 320 is parts in pedal assembly 310.Each pedal assembly 310 is comprised of a pedal 320 and a connecting rod 321.Each pedal assembly 310 is matched rotationally by rotating shaft 322 and spoke 311.322 is attaching partss, can be rotating shaft, can be also the rotating attaching parts of rotational pin one class, by the insider, is known.In each pedal assembly 310, pedal 320 is ends that connect rigidly at connecting rod 321, and the other end of connecting rod 321 connects rotationally by rotating shaft 322 and spoke 311.The two ends of connecting rod 321 are outside connecting and sentencing, can extend the connecting rod of a bit of length, from Fig. 6 and Fig. 7, pedal 320 is the ends that connect at connecting rod 321, and the other end of connecting rod 321 also extends upward the connecting rod of a bit of length after rotating shaft 322 places connect.At rotating shaft 322 places, whole pedal assembly 310 can sway, and this rotating shaft is perpendicular to the rotational plane of wheel basically.Whole pedal assembly 310 seems to be suspended on rotating shaft 322 places, and its rotation is independent of wheel, with the rotation of wheel, does not interfere with each other.The design of this suspension type pedal assembly, make the rotational characteristic of pedal 320 be different from the rotational characteristic of pedal in conventional pedal system.For the pedal in conventional pedal drive system, when the cyclist steps on pedal in order to drive wheelbarrow to advance, pedal is to rotate around the rotating shaft of wheel, and the center of turn of pedal is wheel shaft.Yet, when pedal assembly 310 in use, the cyclist, in order to drive vehicle, in order to support cyclist's self weight, applies a downward power to pedal 320 usually.Because the rotation of rotating shaft 322 is the rotations that are independent of wheel, so, in a whole circulation of trampling pedal, pedal 320 tends to remain on the position lower than rotating shaft 322 all the time.Pedal in suspension type pedal assembly, due to the compensated distance that one section connecting rod is arranged, make the wheel shaft of the liftoff height in its center of rotary motion trace lower than wheel.(consult another patent of my application, the suspension type pedal assembly that rickshaw is used, application number: 2013104681074,2013-10-11).So, when the cyclist rides, it is the pivot center lower than connecting rod 321 that the stepping on of pedal 320 pedaled surface.The pedal of lower position and the reduction that finally makes cyclist's center of gravity, increased the stability that vehicle is ridden, reduced the difficulty that vehicle is ridden, got on the bus more convenient, get off (no matter be getting off of mapping out, or extemporal getting off) safer, more comfortable.

On the wheelbarrow 300 shown in Fig. 6 and Fig. 7, equally also be provided with steady pin components 330.Vertical links 331 in steady pin components 330 can be the integrated extension of connecting rod 321 in pedal assembly 310.Vertical links 331 shares rotating shaft 322 with connecting rod 321.Leg plate 332 is arranged on the top of vertical links 331 equally.

From above-mentioned several examples, used the stand-type wheelbarrow of steady pin components, suspension type pedal assembly or parabolic wheel, in the various aspects of application performance, all be greatly improved.Having higher lateral stability, is the conventional products before being used for substituting, and as the training device of the wheelbarrow of riding, also can increase for this field the wheelbarrow of a new variant.
