Abstract

A kind of energy imitates image and the sensation of riding, and pitches the galloping toy cart of driving force is provided with human body, and it adopts simple two-way sour jujube chain-drive mechanism, toy car can be advanced and can retreat.In the time that toy car retreats, the PA-system in galloping horse body can also send the cry of horse, makes rider feel very witty.

Description

Toy carriage

The present invention relates to a kind of toy, particularly a kind of can riding and with the human body toy carriage (perambulator) driving that jolts for people seat.

Existing tricycle or four-wheeled toy car are generally that the foot-operated driving force, this type toy car of providing both made external form make and animals shapedly can not embody the interesting image and the sensation that drive animal.As health and fitness facilities, it can not make all coordinated movements of various economic factors of rider's whole body.

The existing document of bicycle that utilizes human body weight to drive is recorded United States Patent (USP) 00734702927896,2932041,3001584 and is belonged to this type of bicycle.But the various bicycles that document is recorded, what have could be for driving force when human body moves down, on human body, moving is idle running, have can only be front so that can not retreat.

The invention provides a kind of human body toy car that all can drive that pitches, this toy car can not only advance faster, and can retreat, and utilizes to simulate to drive zoomorphism and feel to increase amusement entertaining and make children reach the object of activity body-building.

Toy car of the present invention by external form as horse or other animal housings, support framework, the part composition such as front and back wheel and driving mechanism.The saddle of this toy car is alive.Can move up and down, pedal also can be up and down, and saddle and pedal connect together by a fixed pulley.In the time that rider sits down, human body weight will be depressed saddle and provide power for advancing, and at this moment both legs loosen, and on pedal, move; Then rider's both legs are stood, human body weight press foot pedal, then power is provided for advancing.At this moment on health, lift, saddle is mentioned, and goes round and begins again, and the weight that once circulates secondary provides power.

Conventionally the power direction that such secondary provides is contrary, for by reciprocal secondary phase power, all convert equidirectional motion (advance or retreat) to, the present invention adopts a circulation link chain (or driving-belt, cog belt) to drive two sprocket wheels (or wheel) to rotate, one of them sprocket wheel is fixed on toy car rear drive sprocket, and another is fixed on vehicle frame.Like this direction of motion of the constant but chain of the transmission direction of sprocket wheel on one side up on one side down, thereby utilize one can folding Ji Jin mechanism, the human body gravity that pitches is passed to chain, chain-driving chain gear transmission, thereby drive toy car to advance.

The setting force bar of Ji Jin mechanism is rotary, in the time that head of the horse lifts, by a rope, setting force bar is rotated, and by a kind of stress, changes to another kind of stress, and toy car just changes into and retreats by advancing.This direction of motion conversion can also utilize human body weight to play braking action.

For the rider of this toy car being paid can the long period continue and obtain speed faster compared with little muscle power, an assist motor can be set on rear drive sprocket, the stator of motor is fixed on car body.Rotor is fixed on hind axle, a contact delay switch is separately installed under saddle, car is during by static startup, utilize the human body driving that pitches, touch delay switch simultaneously, make motor connect a period of time, can not only make like this children can use safely in the situation that not needing any training, thereby and because not needing to start link, motor greatly reduces power consumption, do not need to configure the motor of relatively high power, in addition, because rotor and driving wheel are coaxial, so, both used motor power-assisted also not affect the inertia motion of toy car.

The shell of this toy car adopts sponge, foamed plastics elastomeric material to enrich, and making that the joint component of toy car is neither exposed again can flexible rotating.

This toy car, owing to adopting chain drive, both can advance toy car by the direction of motion of the tight mechanism controls chain of sour jujube, can retreat again, and rider's health can provide driving force that rider is had to ride the sensation more really of animal one on the other simultaneously.Not only there is stronger interest, and can cultivate the harmony of children's sport.

Concrete structure of the present invention is provided by following example and accompanying drawing.

Fig. 1 is the cutaway view of this toy car.Fig. 2 drives Ji Jin mechanism in making toy car forward travel state cut open portion's enlarged diagram.Fig. 3 shows that the tight mechanisms grip of described driving sour jujube drives the schematic diagram of plane.

Referring to Fig. 1.The shell (26) of this toy car is made the shape of galloping horse, before have a wheel (24) controlling party to, after to have two wheels (25) be driving wheel.Head of the horse (1) can rotate around the steel pipe (2) being fixed on front fork, utilize handle (3) movable block in head of the horse (1) can be lifted, nylon rope or steel wire (5) saddle (6) that tension is through in plastic flexible pipe (4) are fixed on conduit (7) one end, conduit (7) can move up and down, and its other end is connected with force transmitting board (8).Force transmitting board (8) is U-shaped, and one end and steel wire rope (9) are hinged and hinged by pulley (10) and pedal (11).Force transmitting board (8) other end, there are four little axles (12) and circular shaft (13), circular shaft (13) is hinged with two setting force bars (14), each setting force bar (14) and two axles (12) composition Ji Jin mechanism, select suitable transmission rod length, can clamp firmly chain or rotate band (15) along with force transmitting board (8) moves together.It is upper that chain (15) motion lower sprocket (17) between upper sprocket wheel (16) and lower sprocket (17) is fixed on hind axle (18), thereby drive trailing wheel to rotate.Situation shown in this figure is that head of the horse is kicked up, the state of toy car in falling back backward.At this moment two contactings of contact-making switch (19), the PA-system that is arranged on horse belly sends the sound of shouting of horse.

Referring to Fig. 2.Setting force bar (14) is connected with axle sleeve (21) by finer wire (20) respectively, and can be along with axle sleeve (21) is together in the upper rotation of circular shaft (13).On axle sleeve (21), be wound around nylon rope (5), nylon rope (5) one end is connected with the movable block (1) on head of the horse, and the other end is connected with the spring (22) being fixed on force transmitting board (8).Spring (22) is attached on force transmitting board (8).Not tension of spring shown in this figure (22), setting force bar (14) is in making toy car forward travel state, both in the time that force transmitting board (8) moves downward, left support force plate A and two little axles (12) clamping chains (15) downwards together with motion, and right setting force bar B does not stress, due to the elasticity of steel wire (20), chain (15) can upwards be slided to jump and pass through, in the time that force transmitting board (8) moves upward, support force plate B is stressed, jump and support force plate A is sliding, if head of the horse lifts nylon rope (5) and draws rotating shaft cover (21) support force plate A and position, B inequality left and right, both there is the state that shown in Fig. 1, toy car falls back.

Ji Jin of the present invention mechanism, on being applied in toy car, also can be applicable on some other mechanical driving device and unidirectional chain locking device, as designed accordingly a kind of Crankless engine, the rectilinear motion of engine piston is driven to an annular link chain chain-driving sprocket wheel by above-mentioned Ji Jin mechanism, rotatablely move thereby convert to.This Crankless engine is easy to change the direction of rotation of sprocket wheel, need not use common gear-box.
