Description

Stand-type wheelbarrow equipped with steady pin components

Technical field

The present invention proposes a kind of stand-type wheelbarrow equipped with steady pin components.More precisely, being one kind pedal (pedal) drive, the stand-type wheelbarrow equipped with steady pin components.

Background technology

Unicycle has been known to insider, is most commonly that the driven, wheelbarrow with seat with pedal, They are widely used for amusement and acrobatics.For a kind of equipment with body-building for amusement, wheelbarrow is to be difficult to association to ride Row." finding it difficult to learn ", although promoting recreational contest, decreases " ride " interest of many people simultaneously.

Also have a kind of wheelbarrow without seat, just had before 5 years many products commercially sold (refer to: Wiki is deciphered, wikipedia, the free encyclopedia).Because it does not have vehicle seat, ride and be more difficult to control balance, So, everybody generally it be called " ultimate wheel (ultimate wheel) " or be referred to as " difficult riding wheel (impossible wheel) ". (sometimes a kind of no seat, pedal fixation wheelbarrow being also referred to as " difficult riding wheel ").Ride this single wheel without seat Car than the reason being provided with the wheelbarrow at seat with greater need for skill is: during cycling, during driving pedal, wheel can swing to side Face, causes car to lose the balance of left and right；Do not choose a place to give a banquet the wheelbarrow of position, every side of car, the lower limb of cyclist and car only have one Individual contact point, that is, cyclist to step in the foot on pedal be unique contact point between car and people；Only lean on a contact point, add Car is can be free-moving all around again, is difficult to make the relative position of cyclist and car, with side perpendicular to the ground Control upwards and must be basically unchanged or basically identical.So it is extremely difficult for wanting to stop wheel from falling down with undesirable angle 's.Otherwise, cyclist is only rubbed with lower limb the wheel not covered, and the side to stoping wheel is fallen, so the no seat of riding Wheelbarrow is then more difficult, needs more skills.

Therefore, market needs a stand-type wheelbarrow that can be driven with pedal, and will have higher lateral Stability, can be used for substituting former conventional products, can be used as the training device of the wheelbarrow of more difficult type of riding, or Person can increase the wheelbarrow of a new variant for this field.

Content of the invention

The invention aims to prepare a kind of than current product have upper side to stability, can be more accurate The wheelbarrow that ground is manipulated by cyclist.For making vehicle stationary, the wheelbarrow of the present invention, one steady lower limb of device above pedal Part, this steady pin components is directed towards the top stretching, extension of pedal, and steady pin components have a leg plate.When the foot of cyclist is seated in When stepping on pedal, the inner side of cyclist's lower limb can keep contacting with leg plate all the time.The inner side of cyclist's lower limb is applied to leg plate Plus-pressure, it is possible to reduce the unnecessary tilt being occurred during stepping pedal, thus increased that car rides is steady Qualitative, also increase the efficiency of the accurate manipulation when turning, climb and fall and rough road travel for the car simultaneously.

By analysis, it can be found that it is identical that wheelbarrow and stilt walk keep the principle of balance, wheelbarrow and stilt walk Operator be so that the movement of wheel or stilt, and control the position of center of gravity by the movement of limbs, thus keeping Balance.Center of gravity mentioned here, refers to that operator synthesizes a center of gravity during entirety with car, between operator and car If position is basically unchanged in vertical direction, the position of centre of gravity of both entirety is also be basically unchanged.For unicycle For, if the position between operator and car is constantly in change, or if can not keeping basically identical in vertical direction, Operator and the respective position of centre of gravity of car are each comfortable changes, then center of gravity when operator and car synthesis one are overall Change continuous, operator and car also just cannot keep balance, because operator is difficult to stand firm on pedal, even for The people of more familiar manipulation skill is also to be very unstable to manipulate car traveling.

Stilt walk is in the very ancient history of China.Stilt used by moderns, have double lift up, singly lift up point.Double lift up many Colligation, on shank, is singly lifted up, and respectively holds the top of every stilt with both hands.The every side of which kind of stilt is all to have two fixations Junction point, double lift up be foot step on place with shank on colligation at two junction points, singly lift up be foot the place of pedaling be connected for two with the place of holding Point.The junction point of this two fixations makes operator and stilt blend together one, maintains one in the vertical direction with ground Common center of gravity.Therefore, operator and stilt can keep balancing, and not only can stably advance moreover it is possible to perform the literary composition of a variety of programs Military stunt.Between every lower limb of operator and every stilt, only one of which junction point can not play stilt.Investigate stilt walk Principle after, it can be found that every foot of on the pedal unicycle operator of standing, only on pedal connects Point, if the junction point if there are two fixations, just can make operator stand firm on pedal, and stably manipulation car is advanced or done Other work.

Therefore, the unicycle that stand-type wheelbarrow proposed by the present invention is proposed in the industry before mainly changing Structure, is provided with the steady pin components being connected with car body above pedal, and its effect is that the lower limb enabling cyclist leans on Live car body, except on pedal pedal sufficient place in addition to, increased a substantially stationary junction point, make every lower limb and the car of cyclist After having two junction points between body, cyclist can stand firm on pedal, stably manipulates car.On each steady pin components Device has leg plate, is respectively intended to mutually lean on so that both feet are during stepping pedal for the two lower limb contacts of cyclist, two lower limbs begin Can keep contacting mutually leaning on leg plate eventually.Thus, improve the car stability ridden and the accuracy manipulating.

Some examples of the present invention propose can be using oval wheel.It is known that in two pedal cycle rotations Cycle in, two pedals vertically in line when, cause " dead point " exerting a force, applying rotating torque to wheel has essence On difficulty.This can be overcome difficult using the wheelbarrow of parabolic wheel.

There is in the industry experience personage after check detailed narration hereafter with reference to drawing, the skill of the present invention can be further appreciated that Art feature and other relevant advantage.

Specific embodiment

Refering to Fig. 1 and Fig. 2, this is a kind of stand-type wheelbarrow 100 equipped with steady pin components proposed by the invention.Solely Wheel car 100 includes single 110, two pedals 120 of wheel and two steady pin components 130.Two pedals 120 respectively with wheel 110 is matched, for driving car 100.Steady pin components 130 are matched with pedal 120, are connected to the inner side of each pedal 120. Wheel 110 only has single spoke 111, is connected across wheel diametrically.In other instances, the structure of wheel may with present The technology known is slightly different.Two pedals 120 are rotatably arranged in the both sides of wheel 110 respectively, and they can support cyclist, Stand for cyclist, enable cyclist to carry out driving moment 110. using pedal 120.Each steady pin components 130 includes one and hangs down Straight connecting rod 131, it typically stretches upwards out at pedal 120.(used when here steady pin components 130 being described " direction is upwards " and terms such as " direction are vertical ", for being orientation when car 100 is in use, when Fig. 1 illustrates use The orientation of car 100.Direction referred herein refers to the direction of " usual " meaning, is not the direction in " accurate " implication, because Steady pin components 130 are as pedal 120 rotation, so during stepping on pedal, the direction of cyclist's lower limb can be after little Little change).Has a leg plate 132, its surface and height and position just can support and ride on each vertical links 131 The lower limb of car people.So two steady pin components, respectively there is one and lean on lower limb surface, after respective and described pedal assembly is matched, when Cyclist stands in when riding on pedal, and two lower limbs of cyclist can keep contacting with by lower limb surface.

On wheelbarrow 100 shown in Fig. 1 and Fig. 2, vertical links 131 is connect pedal 120 and leg plate 132 one Support bar；However, in additional examples, the slightly different configuration of steady pin components 130.For example, vertical links 131 can be with hinge Chain, to connect, can fold gathering downwardly against the direction of pedal 120 and get up, (it can however not to fold towards wheel direction, Because the lower limb of cyclist is towards the inner side direction force of lower limb, vertical links 131 is necessary for this and keeps rigidity).Except this In addition, vertical links 131 and pedal 120 can be with commaterial integrally molding.Or, vertical links 131 with by lower limb Plate 132 can be with commaterial integrally molding.

It is provided with one on steady pin components and leans on lower limb surface, be leg plate in this example by lower limb surface.Foot as cyclist After standing on pedal 120, lower limb is put into the position of leg plate 132, cyclist's inboard leg presses to leg plate 132, with leg plate 132 are close to, and the lower limb of cyclist is supported.In the circulation stepping pedal, two legs are all and leg plate cyclist all the time 132 are close to.Increase between every lower limb of cyclist and car as two junction points, therefore increased stablizing of car side Property.With the lower limb of cyclist compared with only having one junction point of foot and pedal between car, cyclist just can manipulate with comparalive ease Wheelbarrow.Every lower limb of cyclist and car have the difference of effect and " height between two junction points and only one of which junction point Lift up " identical, it is also apparent.If it is known that only one of which is connected between every lower limb of operator and every " stilt " Point can not play " stilt ", and beyond the foot of operator is connected with the footboard of " stilt ", shank position also needs to and " stilt " The bar that upwardly extends pinion, after having two junction points, just can do various " stilt " performance.But, the second of wheelbarrow Individual junction point, can not bundle fixing between shank and leg plate 132, in order to ensure safety, cyclist to be allowed can be at any time Without restriction lower limb is departed from car, safely jump off from car.Obviously, after being provided with leg plate 132, with laterally steady Qualitatively increase, cyclist can more easily manipulate the direction of car；When slope or rugged landform travel, cycle People can more easily stablize onboard；When riding and when getting on or off the bus, cyclist can more easily prevent unintentional side To tipping.Leg plate 132 can be made with a slightly soft class material (such as: rubber).The leg plate 132 of car both sides Can have slightly concave curved surface with lower limb contact surface, the leg inside contact surface substantially matching with cyclist.Steady pin components 130 Can arrange to tilt slightly outwards, be beneficial to cyclist and be easy to leg plate 132 is pressed.These performances are all advantageous for cycling The leg of people keeps good mechanics to be connected by friction and leg plate 132.

Because the steady pin components 130 of car both sides be combined with pedal 120 after position of centre of gravity not in pedal 120 spindle central Vicinity, when the lower limb of cyclist is not yet in place, the steady pin components 130 of car both sides can be around the spindle central of footboard 120 Freely fall down forward or backwards it is impossible to make to maintain a certain distance between two pieces of leg plates 132, so two steady legs One connect band 140 will be set between part 130.Connect band 140 make two pieces of leg plates 132 will not move out certain away from From when the steady pin components 130 that the lower limb of cyclist makes side are in vertical position, the steady pin components 130 of opposite side also can be located A certain distance will be remained between similar position, two pieces of leg plates 132.Connect band 140 can adopt not same Formula or different materials: elastic bands or the soft bar of plasticity (as shown in Fig. 1, Fig. 2), connect upper in two vertical links 131 Portion.

Another makes two pieces of leg plates 132 keep the method for certain distance is to add one in the lower section of each pedal 120 Weight is so that the position of centre of gravity after surely pin components 130 are combined with pedal 120 is less than the spindle central of pedal 120, closer to ground Face.Now, even if two lower limbs of cyclist are not yet in place, steady pin components 130 generally also tend to vertically on one's feet, no Fall down before and after meeting.

As shown in Figures 1 and 2, vehicle wheel spoke 111 has multiple junction points 121, they are for connecting pedal 120. The spacing at two pedals 120 and wheel 110 center can supply cyclist's selection according to performance and hobby.Vehicle wheel spoke 111 On multiple junction points 121 be exactly change between two pedals 120 apart from when the junction point selected.

Fig. 3 shows the embodiment that another kind can change distance between two pedals 120.In this example, in spoke 111 It is provided with a guide rail 122 so that two pedals 120 can slide along the track, can be used to be finely controlled connected two The distance of individual pedal 120 and position.Guide rail 122 can also be slide rail, when two pedals 120 are in order to promote stepping of car Cheng Zhong, the distance between two pedals 120 can be arranged to variable configuration.Now, two pedals 120 are to have been applied bias (with spring or other method), after bias eliminates, can automatically restore.That is, outside two pedals 120 are not subject to During power, mutual and wheel 110 center maintains a certain distance, when exposed to external forces, the meeting of the distance between two pedals 120 Become remote or become nearly (become remote or become and be closely depending on direction and the size that person for driving a car is exerted a force), after external force cancels, two feet Pedal and between 120, be returned to original distance.It is known that in normal conditions, pedal when stepping some point positions of circulation is It is difficult to apply thrust moment, due to the configuration set by slide rail 122, be to automatically adjust pedal 120 and wheel 110 center The distance between, therefore this configuration makes person for driving a car also can easily apply out thrust moment in these point positions, promotes car fortune OK.As can be seen here, being technically characterized by comprising the steps as follows: because of the pedal 120 on pedal assembly of this example is to be rotatably connected to spoke 111 On, so pedal 120 is rotationally connected with wheel by spoke 111, each own rotation of each pedal 120 Axis, the distance between two pivot centers of two pedals 120 can adjust, in other words, pedal assembly and car Rotate the pivot center of connection between wheel, can adjust with the distance between the pivot center of wheel.

Fig. 4 and Fig. 5 shows another example proposed by the invention, and Fig. 4 is the perspective view of wheelbarrow 200, and Fig. 5 is only The side view of wheel car 200.In this example, wheelbarrow 200 and wheelbarrow 100 difference on Fig. 1, Fig. 2 are, using ellipse Circular wheel 210 instead of the wheel 110 of circle.Miscellaneous part is all similar, and pedal and stabilisation part are arranged on list On root spoke 211.Oval wheel can compensate the difficulty that during some point positions, wheel is applied with moment, particularly when two feet Pedal the most difficult when being on vertical straight line.Equally, wheelbarrow 200 may also set up rail plate, its function also as Mentioned above.

Fig. 6 and Fig. 7 shows another example proposed by the invention, and Fig. 6 is the perspective view of wheelbarrow 300, and Fig. 7 is only The side view of wheel car 300.In this example, the left and right of wheelbarrow 300 two pedal 320 is not directly to connect in spoke 311 On, each pedal 320 is one of pedal assembly 310 part.Each pedal assembly 310 is by a pedal 320 and Bar connecting rod 321 is formed.Each pedal assembly 310 is rotationally matched with spoke 311 by rotating shaft 322.322 is one Connector, can be rotating shaft or the rotatable connector of rotational pin one class, known to insider.Each In pedal assembly 310, pedal 320 is the one end rigidly connecting in connecting rod 321, the other end of connecting rod 321 pass through rotating shaft 322 with Spoke 311 rotationally connects.The connecting rod of a bit of length, beyond connecting place, can be extended in the two ends of connecting rod 321, from Visible on Fig. 6 and Fig. 7, pedal 320 is the end connecting in connecting rod 321, and the other end of connecting rod 321 connects at rotating shaft 322 Afterwards, also extend upward the connecting rod of a bit of length.At rotating shaft 322, whole pedal assembly 310 can pivoting, this turn Axle is substantially perpendicular to the rotational plane of wheel.Whole pedal assembly 310 seems to be suspended from rotating shaft 322, its rotation It is independently of wheel, the rotation with wheel does not interfere with each other.The design of this suspension type pedal assembly is so that the turning of pedal 320 Dynamic characteristic is different from the rotational characteristic of pedal in conventional pedal system.For the pedal in conventional pedal drive system, When cyclist steps on pedal to drive wheelbarrow to advance, pedal is around the axis of rotation of wheel, in the rotation of pedal The heart is wheel shaft.However, when pedal assembly 310 use when, cyclist in order to drive vehicle, in order to support the weight of cyclist itself Amount, generally applies a downward power to pedal 320.Because the rotation of rotating shaft 322 is independently of the rotation of wheel, whole Individual trample in one of pedal circulation, on the position that pedal 320 always tends to be held below rotating shaft 322.Suspension type pedal Pedal in assembly, due to having the compensated distance of one section of connecting rod so that the liftoff height in the center of its rotary motion trace is less than car The wheel shaft of wheel.(another patent applied for refering to me, the suspension type pedal assembly of rickshaw, application number: 2013104681074,2013-10-11).So, when cyclist rides, the stepping on of pedal 320 is pedaled surface and is less than connecting rod 321 Pivot center.The pedal of lower position and the reduction finally making cyclist's center of gravity, increased the stability that vehicle is ridden, Decrease the difficulty that vehicle is ridden, get on the bus more convenient, get off (that either maps out gets off, or extemporal get off) more pacify Entirely, more comfortable.

On wheelbarrow 300 shown in Fig. 6 and Fig. 7, equally it is also provided with steady pin components 330.Hanging down in steady pin components 330 Straight connecting rod 331 can be the extension of connecting rod 321 integration in pedal assembly 310.Vertical links 331 is shared with connecting rod 321 and turns Axle 322.Leg plate 332 is equally provided in the top of vertical links 331.

From above-mentioned several examples, employ standing of steady pin components, suspension type pedal assembly or parabolic wheel Formula wheelbarrow, is all greatly improved in the various aspects of application performance.There is higher lateral stability, be can be for replacing For former conventional products, as the training device of wheelbarrow of riding, the wheelbarrow of a new variant also can be increased for this field.
