Abstract

The utility model relates to a toy horse walking with four legs, which is a children's toy with realistic actions. The spring is used as the motive power, and a rocking plate with off-center is used to drive. Four legs are driven to bell crank, and cause the cross actions of four legs when the horse is in advancement; the legs bends when the horse swings forwards, unbends and touches down when the horse swings backwards, and can also make the actions of head shaking, fishtailing and turning. The making material of the utility model mainly comprises plastic, iron sheet and wire. The utility model can be developed by common toy making factories.

Description

Toy horse walking with four legs

The utility model four leg walking toy horse vehicle is a kind of clockwork spring toy for children.

Existing similar toy mostly is the four-wheel rolling or straight leg is taken a step, and leg can not be crooked.

The purpose of this utility model provides a kind of toy horse vehicle true to nature that moves.

The scheme that the utility model adopts is that designing a kind of is power with the clockwork spring, and through eccentric rocker transmission, crank throw drives the horse leg, can bent stretch the toy horse vehicle of taking a step.

Accompanying drawing 1 is this horse outline drawing, and horse housing and four legs are all made of plastic.

Accompanying drawing 2 is this horse walking movement decomposition figure: 1. four legs directly stretch ground.2. the left front leg right rear leg is stretched the back pendulum, and horse advances.The crooked forward swing of other two legs is because of rhaeboscelia is shorter than straight leg, so hoof is liftoff.3. forward swing two rhaeboscelias are stretched and are landed, and back pendulum two legs still stretch, and four legs stretch and land again.4. horse RAT, left back leg stretch the back pendulum, and horse advances.The crooked forward swing of two legs changes action then over to and 1. finishes continuously because of four actions of toy in addition, and constantly circulation stagnates until the clockwork spring pine.Waving advances does not topple over so horse can rise and fall.

Horse leg integral plastics is molded, and knee joint, coffin joint are elasticity bending shape, and crooked trend is all arranged, and should adopt the polypropylene plastics manufacturing, but the lasting folding of elasticity is tens thousand of inferior.Preceding stifle elasticity bending position opposite.Horse leg swing flexure operation principle is shown in accompanying drawing 3A-D: A, crank throw are left-handed up, take out knee on the thigh bone, and the horse leg is crooked and around big leg joint forward swing.B, crank throw backspin were inserted knee, horse leg by curved change directly under the thigh bone.The C crank throw below dextrorotation, thigh bone is inserted down, the horse leg stretches the back pendulum around the joint.Revolve on D, the crank throw, take out on the thigh bone, the leg bending connects change and makes A.In view of the above, as long as turn on the contrary the coaxial both sides of toy horse vehicle thigh bone crank throw, the diagonal orientation turns to identical, just can finish action shown in Figure 2.

The utility model is to adopt eccentric rocker driving method, realizes this requirement.(a kind of eccentric rocker driving method arranged: the crank shaft that several eccentric throws are identical in the machine driving, if eccentric end is all by sliding supporting the closing in the hole on the orifice plate, each hole is identical with each crank throw axis of rotation position again on the plate, then arbitrary crank throw rotates, will shake orifice plate, make all the other crank throws equidirectional, with the speed rotation, this orifice plate claims eccentric rocker.）

Accompanying drawing 4 is a toy horse vehicle internal structure stereogram, and accompanying drawing 5 is its vertical view.This structure is that material is made with iron sheet, iron wire mainly.Tailgate (2) is equipped with at stature behind the horse (1) rear portion, and clockwork spring movement (5) is equipped with at the middle part, and stature (7) is equipped with the headstock (8), headstock swinging axle (9) before the horse.Two places are vertically with one heart by rivet (10) riveting connection alive up and down between front and back stature (1), (7), and angle can swing.Clockwork spring movement (5) output is a crank throw, can drive after crank (3), preceding crank throw (6) rotation by the eccentric rockers in five holes (4), makes the walking of horse four leg walking.(4) front aperture is colluded syncranium frame swinging axle (9) horse is shaken the head, and back stomidium colludes connection tailgate (2) can make horse wag the tail, and stature (7) can also make horse turn before plate was moving.

The utility model is compared with existing similar toy, and it is simple to have a transmission, moves characteristics such as true to nature, and general Toy Factory all can develop, and this toy also can be made into other four legs animals.

Claims (2)

1, the utility model four leg walking toy horse vehicle is a kind of toy for children true to nature that moves, this toy mainly drives front and back crank throw (3), (6) rotation by the clockwork spring movement (5) that is contained in the rear body (1) by eccentric rocker (4), and stretch the horse leg of taking a step by the thigh bone driving song that is connected in the crank throw end and form, it is characterized in that:

A. there are knee joint, coffin joint to be the horse leg of elastic bending shape,

B. have and inserted the thigh bone that knee can make the horse leg stretch,

C. clockwork spring movement (5) output is a crank throw,

D., the eccentric rocker (4) that transmits outputting power is arranged.

2, by the described four leg walking toy horse vehicle of claim 1, it is characterized in that:

A. crank throw (3), (6) two end cranks before and after turn on the contrary,

B. crank throw (3), (6) before and after the clockwork spring movement (5), each crank throw eccentric throw is identical.
