Detailed description of the invention

In FIG, Reference numeral 10 totally represents according to toy of the present invention, and described toy comprises the bracket 12 supported by two wheels 142.Wheel 14 is arranged on bracket 12, so that around common axis line D pivotable, and they are driven independently by independent electro-motor (not shown), described electro-motor is guided by suitable circuit, allowing toy along straight ahead according to the direction of rotation of wheel and speed, move backward, around itself to rotate or along curve rotation etc., therefore by means of suitable Long-distance Control, different motions is advantageously controlled by toy.

Bracket 12 extends along with the principal direction Δ of the pivot axis D perpendicular to wheel, and its supports sliding part 16, and described sliding part 16 can parallel to the axis the translationally motion of Δ under the effect of the suitable motor guided by toy control circuit.This sliding part comprises such as two parallel bars 18, described two parallel bars 18 are guided with the cylinder body 20 of bracket 12 one by respective, one or several springs (invisible in the drawings) serving as energy storing device are between bar 18 and cylinder body 20, when sliding part 16 moves to closer to bracket 12, spring-compressed, otherwise and when sliding part 16 towards bracket/sliding part unit extended position release time, the energy stored by these springs turns back to sliding part 16.In addition, it should be noted that the complete extended position at sliding part, the end of sliding part protrudes past the circumference of wheel 14, and therefore can with earth surface.

Main body 22 one of bracket 12 and toy, described main body 22 itself is provided with projection 24, and described projection 24 protrudes past the diameter of wheel 22.According to feature of the present invention, with on extension the same side of sliding part 16, the surface 28 that the far-end 26 of this projection 24 has and to point to after toy (namely according to Fig. 1 and 2 towards left side).This surface 28 forms the first folder portion or cheek of clamping device, and described folder portion or cheek will be described by concrete reference diagram 3d hereinafter.

Projection 24 also carries the supporting member of such as ridges 30 at its far-end 26 place, described supporting member can form the first liner with earth surface, and its structure will be described by concrete reference diagram 3c and 3d hereinafter.

In addition, the far-end 32 protruding past the diameter of wheel 22 of sliding part 16, is provided with the element 34 in formation second folder portion, and described element 34 is relatively arranged substantially with the surface 28 forming the first folder portion.In the drawings, this element 34 illustrates as dismountable bow, but this concrete form only provides in the mode of non-limiting example.

The far-end 32 of sliding part 16 also comprises the element 36 of such as surface or ridges, described element 36 Fig. 1 and 2 structure middle finger earthward, and described element 36 is formed second contact pad designed, be easy to illustrated position in fig 1 and 2 and form the ground supporting point of toy.

Toy can also provide one or several Optical devices 38, and (a), such as camera or lamp, its optical axis δ forms fixing angle relative to bracket with the principal direction Δ of the toy body of this bracket one to Fig. 4.Such as, when toy rolling, this device allows to illuminate before toy, and/or gathers the video image from the operation place that toy is observed.

(and Fig. 3 a, be similar to Fig. 2 and a) illustrate so-called " acquiescence " position that toy among some positions is easy to take, other position is described with reference to figure 3b to 3d Fig. 2 a and 2b hereinafter.

In this position, toy puts on the ground 42 by three supporting-points: second contact pad designed 36 of two contact points 44 of wheel 14 and the far-end of sliding part 16.

As mentioned hereinbefore, sliding part 16 opposing brackets 12 forms telescopic unit, and therefore it translationally can move under close control is the motor effect guaranteeing translation between extended position 40 (Fig. 2 a) and retracted position 40'(Fig. 2 b).

The displacement of sliding part 16 causes the displacement of the ground supporting point of the second liner 36, and cause the change of the gradient of bracket axis Δ explicitly, and the change of the gradient of different elements therefore causing toy and be connected thereto: especially, the scene that can adjust the axis δ of camera 38 is directed, and when two take turns 14 driven with contrary direction time the azimuth orientation that causes around himself rotation due to toy.

On the other hand, default location 40 or 40' are that positions: by being arranged between sliding part and bracket and previously by the resilience that the spring compressed is unexpected, and toy prepares to jump (leaper position).

By location toy, axis Δ is made to have large inclination more or less, long-jump or high jump can be contributed to: such as, the position 40 with the axis Δ slightly tilted of Fig. 2 a will contribute to the length of jumping, and the position 40' with more acclivitous axis Δ of Fig. 2 b will contribute to the height of jump.

Fig. 3 a to 3d and similar but illustrate the diverse location that toy of the present invention can take for Fig. 4 a to 4d of perspective view.

Fig. 3 a and 4a corresponds to just with reference to " acquiescence " position that figure 2a and 2b describes.

It is settling position naturally, and in described position, toy is put on the ground by three supporting-points (contact point 44 of wheel and the second liner 36).Suddenly discharged via the second liner 36 by spring energy (arrow 46 indicates) as described hereinabove, this position allows to roll on the ground especially, rotate, through barrier etc., and being configured for the ready position of jump, this energy is delivered to toy body by the reaction force on inertia and ground thus is caused toy body to jump.

Fig. 3 b and 4b illustrates another so-called " falling to put " position 48, and in this position 48, the projection 24 of toy body is pointed to upward, as the far-end 32 of sliding part 16.

In this position 48, there is not the 3rd supporting-point, and toy only relies on two points 44 of wheel 14 and earth surface.In addition, sliding part 16 relative to bracket 12 relative position this fall pendulum position be not particular importance, put position at this, folder portion 28 and 34 does not operate purposes, does not also have contact pad designed 30 and 36, does not provide fault offset further in this position.

Can arrive pendulum position 48 by the rotation of toy body (arrow 50) from position 40, this rotation is caused by the instruction accelerated backward suddenly: due to inertia, wheel moves hardly, and therefore also moves hardly around the main body 22 of axle D pivotable.

In this position 48, toy be centrally located on axle D, therefore this position is unstable naturally, and can only by the feedback of signal by guiding the control of the motor of wheel to maintain, and wherein said signal is such as by being included in orientation sensor in toy body or inertial sensor is carried.

This position 48 can be centre position, with the selection of wait action or be switched to another location (such as illustrated position in Fig. 3 c and 3d), or the game position of maturation, there is the possibility of rolling, rotation etc., also there is the FEEDBACK CONTROL from inertial sensor, to make toy body maintain illustrated position evenly during these orders of displacement.

Fig. 3 c and 4c illustrates another so-called " shooting " or " sending bullet " position of toy.This position 52 by following means by default location 40 or fall pendulum position 48 and obtain: make main body with the mode pivotable (arrow 54) identical with in-position 48, the unexpected instruction namely by making toy body to take turns almost motionless post-acceleration around axle D pivotable due to inertia.

This position is settling position naturally, because toy is by two contact points 44 of three supporting-points, i.e. wheel 14 with put on the ground with the first liner 30 of the projection 24 of toy body and bracket one, this liner is when rotation 54 terminates and earth surface.

But, should note, in alternative embodiments, the ledge of toy body or projection 24 (and therefore first contact pad designed 30) can be omitted, the 3rd supporting-point then by sliding part 16 outstanding far-end or be made up of the stirrup (if such stirrup is arranged on the end of sliding part) forming the second folder portion 34.

In position 52, second liner 36 and the second folder portion 34 settle relative to one another, this allows to make them directed towards object (representing with cube 56), when these springs are discharged suddenly to the translation of its retracted position by the energy of the rear spring compressed from its extended position by sliding part 16, described object can serve as projectile.The release of spring and sliding part have the effect of the energy transferring of spring to object 56 via the second liner 36 and/or the second folder portion 34 (arrow 58) to returning suddenly of extended position.It should be noted that the compression/springback process of spring is identical with skip functionality, but in this article, the energy transferring stored by spring, to exterior object, to promote object away from toy, but not promotes toy by the reaction force on ground.

Fig. 3 d and 4d also illustrates another possible so-called " clamping " or " crawl " position of toy.

This position 60 is roughly identical with firing point 52, is not uniquely both sliding part 16 and is in now its extended position but not is in its retracted position, and do not use the unexpected release of energy.Exactly, at clip position 60, the route-variable (between the compression period of spring) of sliding part is used for gripping objects (representing with cylinder 62), this action is caused towards the progression translation in the first folder portion 28 (arrow 64) by the second folder portion 34, here, sliding part 16 is made to move from its extended position towards its retracted position.It should be noted that clamping keeps moderate, the energy for sliding part 16 translation produced by motor is absorbed by spring substantially.As illustrated, the camber member of flexibility also can be provided as the second folder portion 34, and its elasticity will allow any excess compression avoiding object 62.Then clamped object will be shifted, and is placed in another position (discharging clamping by the counter motion of sliding part 16) etc.

Although it should be noted that two positions just described are called " shooting " or " clamping " position, such appointment limits never in any form, and other interaction except shooting or clamping also can be expected.This position (52 or 62) must take the interactional ad-hoc location for allowing to be similar to or to be different from default location simply as, and take the position for toy relies on two wheels to preserve the stable equilibrium as, wherein the far-end of sliding part points to ground, second folder portion can be parallel to ground moving in a controlled manner, further away from each other or closer to the first folder portion.

We will describe the example according to the mechanism for making sliding part be shifted by equipment/releasing of the present invention now with reference to figure 5 and next.

It should be noted that on these figure, represented by the identical reference numerals of increase by 100 with those identical or similar elements of previous figure or part.

This mechanism totally represented by Reference numeral 100 according to the present invention comprises sliding part 116 at one end, described sliding part 116 has liner 116a at its free end, and two bars 118 are rigidly fixed on described sliding part 116, be slidably received in two cylinder bodies 120, pedestal 102 one of two cylinder bodies 120 and this mechanism, this mechanism itself and bracket one.

Two springs 122 are by being at one end bearing on shoulder 116b, being bearing on shoulder 104 and placing around two bars 118 and respective cylinder body 120 thereof respectively in opposite end, described shoulder 116b is formed on sliding part 116 at the root place of bar 118 and bar 118 coaxially, described shoulder 104 is formed in cylinder body 120, at the opposite position in the aperture of cylinder body 120, corresponding bar 118 is engaged by described aperture.

These springs are required to be object stored energy, wherein when the pedestal 102 that sliding part 116 is shifted closer to bracket, spring-compressed, and on the contrary, when described sliding part 116 discharges towards extended position, the energy stored by these springs turns back to sliding part 116.

In addition, arm 130 is hinged on sliding part 116 around axis 132 in the region of its one end, and is included in the finger piece 134 in the region of its opposite end and protuberance in the middle region 136, and its purposes will make an explanation hereinafter.

Arm 130 can around axle 132 pivotable in the plane being parallel to the plane that sliding part 116 slides.

Roughly plate-like rotating part 140 is pivotably mounted on pedestal 102 around the axle 142 that the pivotal axis 132 with arm 130 is parallel.This rotating part defines the lower cam face 144 being suitable for cooperating with finger piece 134, and described finger piece 134 applies against described cam face under the effect produced by spring 122, and spring 122 keeps capturing sliding part 116.

Part 140 is driven by suitable motor apparatus, preferred stepper motor (not shown).Guide this motor in response to control unit, described motor is along a direction or drive along other direction.

Especially, should understand according to reading described below, the present invention can utilize and implement with simple " brush " electro-motor of direct current operation, therefore, when very simply guiding logic, this single and simple motor but be enough to performs the loading of stored energy, locking and all operations needed for release.

Cam face 144 comprises some regions, now will with reference to figure 6 and the angle position of quoting rotating part 140 and quote finger piece 134 confronting parts 140 be pressed on cam face the distance of the pivot O defined by its axle 142 to describe described some regions in detail.

First area 144a is such region, and when rotating part 140 rotates along the clockwise direction in Fig. 6, this region reduces to the distance of axle 142 gradually at the some A and putting between B relative to center O ultimate range.Therefore, when part rotates in the direction, it forms the traction region for the power of the opposing spring 122 of sliding part.Cross this B and until some C formed ridge, cam face forms roughly semi-circular indentation 144b, and finger piece 134 is suitable for entering into wherein, and this will be described in more detail below.

Cross a C, between a C and D, cam face 144 forms the second roughly semi-circular indentation 144c of approximate centre on an O, to receive screw 142.

Ensuing region 144d is the region of slightly protruding, and it is generally oriented to radially walks far from an O, until some E, forms another ridge.

Section 144e is defined between an E and F, and along with rotation continues, described section 144e puts O gradually further away from each other, and some F and ensuing region 144f forms bending and convex surface, at region 144f more obviously near the periphery of rotating part, until some G.

Point G and H defines the support 144g for finger piece 134, and the radial distance of some H range points O is identical with some A.Therefore region 144h is the circular sector of center at an O.

The shape of the cam face 144 that Fig. 6 accurately illustrates should be thought of as and belong to the present invention.

Mechanism 100 comprises ratchet 150 further, described ratchet 150 is arranged on pedestal 102, so that around axle 152 pivotable parallel with axle 142 with axle 132, this cam follower comprises the pallet 154 being suitable for cooperating with the protuberance 136 with arm 130 one, and pressurizeed rotatably along the clockwise direction in Fig. 6 by spring such as spiral or belleville springs, the point of the ratchet of holding of spring represents with Reference numeral 156.

Ratchet also comprises and is suitable for acting on the working surface 158 on instant shut-in (fugitiveswitch) 160, and two terminals of described instant shut-in 160 are connected in a not shown manner to control unit.Advantageously, arm provides two generally flat and isolated part 130a, 130b (see Fig. 5), and protuberance 136 laterally extends between these two portions, and ratchet 150 is made as the part that its thickness is less than the distance between these two parts 130a, 130b, can partly enter into the space defined between described two parts, and to cooperate with protuberance 136 wherein.

Fig. 7 a to 7e show when sliding part 116 be in extension state, be then in retracted mode, then under the effect of spring 122, be discharged into suddenly jumping post time toy different attitudes.

Therefore, Fig. 7 a illustrates the situation that sliding part 116 extends to greatest extent with it, and toy is stably put on the ground by means of the liner 116a of two wheel 22 and sliding part, and the angle between slip axis Δ and ground is approximately 25 to 40 °.

As finding hereinafter, sliding part 116 is retracted gradually, the equilbrium position of toy changes gradually, enters into illustrated centre position or as illustrated position in figure 7 c in fig .7b, and the angle between its axis Δ and ground is maximum and be such as approximately 80 to 85 °.

Fig. 7 d and 7e illustrates the starting stage that toy jumps along the direction being roughly axis Δ, and the unexpected release of the energy that this jump is gathered by the spring 122 of motion 100 causes, as finding hereinafter.Therefore, Fig. 7 d illustrates the almost vertical jump of illustrated position in Fig. 7 c, and Fig. 7 e illustrates the longer jump that illustrated position performs in Fig. 7 d.

We will explain that motion 100 that its structure has described hereinbefore can selectively equip sliding part 116 until maximum retraction position (allowing to arrive the attitude of Fig. 7 c) discharge it to perform if illustrated jump or equipment sliding part 116 are in figure 7d until middle retracted position (allowing to arrive the attitude of Fig. 7 b) then also discharges it to perform the mode as illustrated jump in figure 7e now.

In Fig. 8 a to 8h, illustrate the first situation, and illustrate the second situation in Fig. 9 a to 9k.It should be noted that on these figure, seen many Reference numerals omit in figure 6, not make these accompanying drawings too loaded down with trivial details, its ratio is less than the ratio of Fig. 6.

It shall yet further be noted that, on the view in Fig. 8 c, 8d and 9c to 9k, arm 130 illustrates as the view of partial cut, to illustrate ratchet 150 and different positions thereof fully.

In Fig. 8 a, the position of rotating part 140 corresponds to the position of Fig. 6, and the finger piece 134 of arm 130 is positioned at the level place of the some A of cam face 144.

Rotating part 140 drives along the clockwise direction in figure, and finger piece is little by little drawn towards center O (Fig. 8 b) by the region 144a of cam face, until arrive the recess 144b (Fig. 8 c) between B and C.Between this moving period, potential energy accumulates in spring 122.

It should be noted that this orientation contiguous, protuberance 136 stresses on ratchet 150 at pallet 154 place of ratchet 150, and resist to make it power applied by its oneself spring in the counterclockwise direction and rotate, working region 158 is pressed on the working portion of switch 160.

Start along with electro-motor continues to rotate, recess 144b moves towards the right side in figure gradually, also little by little moves along clockwise direction (Fig. 8 e and 8f) to make arm 130.

A certain intermediate angular position between these figure of Fig. 8 f and 8g, recess 144b can not the finger piece 134 of keeping arm 130, and under the impact of the traction applied by spring 120, finger piece ejects from recess 144b, by making finger piece through forming the C of release areas and passing through to be released (Fig. 8 g) to arm plus-pressure towards right side suddenly.

Finger piece 134 is released, and the energy gathered during previous stage by spring 122 also discharges, and advances sliding part 116 fiercely with the extended position towards sliding part 116, therefore causes illustrated jump in figure 7d.

It should be noted that region 144c, 144d, 144e and 144f of cam face form the low profile region not allowing to hinder release above-mentioned.

The rotation of electro-motor continues, and to complete rotation over 360 deg., therefore the position of Fig. 8 h corresponds to the position of Fig. 8 a.

It should be noted that the rotation due to arm 130 in this article, make it to take in Fig. 8 g illustrated inclination or tilt more significantly, protuberance 136 can walk around the pallet 154 of ratchet 150 between extended peroid, therefore not hinder the extension discussed.

With reference to figure 9a to 9k, will explain now by motion 100 take to perform sliding part 116 in the middle of retract and therefore perform the different phase of illustrated longer jump in Fig. 7 b and 7e.

Fig. 9 a to 9c corresponds to Fig. 8 a to 8c, and the position of different elements is identical.

Between the position of Fig. 9 c and 9d, ratchet 150 pivotable gradually under the effect of protuberance 136 pairs of pallets 154, and in Fig. 9 d, switch 160 is closed under the effect of the working region 158 of ratchet.

This is closed and is detected by the control unit of electro-motor, and closes in response to this, and first the rotation of rotating part 140 continues in small angle range, until the position of Fig. 9 e, to guarantee protuberance 136 completely on pallet 154, as illustrated in the figure.

After this stage, the direction of rotation of rotating part is reversed by electro-motor, as by the arrow diagramming of Fig. 9 f, and therefore allow the finger piece 134 of arm 130 to move away from pivot O, but protuberance 136 starts the top against pallet 154 and interrupts this motion, as illustrated in Fig. 9 f that this is identical.This situation corresponds to the retraction of the less sliding part obtained than the operator scheme at Fig. 8 a to 8h, and the settling position of the correspondence of toy is positioned at the position of Fig. 7 b in this article.

Along with rotation in the counterclockwise direction continues (Fig. 9 g and 9h), the effect due to pallet 154 pairs of protuberances 136 of arm and the finger piece 134 can not following cam face again leaves this surface, until the region near some D of cam face 144 towards the right side in figure to finger piece 134 plus-pressure, thus therefore make finger piece 130 along clockwise direction around its rotating shaft 134 pivotable.

Therefore, observe in Fig. 9 i, protuberance 136 is very near the free end of pallet 154, and in Fig. 9 j, protuberance 136 discharges on from the maintenance of pallet.Therefore arm discharges, and the energy gathered by spring 122 can discharge, and is delivered to sliding part 116, and carries out the jump according to Fig. 7 e.

Finally, rotation in the counterclockwise direction continues, until the situation of Fig. 9 k, this situation corresponds to the situation of Fig. 9 a.

Undertaken according to Fig. 8 a-8h (subvertical jump) or according to the selection of Fig. 9 a-9k (longer jump) between the control of mechanism by receiving the corresponding instruction that sent by remote control.In a first case, carry out the complete rotation of rotating part, when inertance element detects the vibrations lifted off corresponding to toy, the rotation of stopping cam profile.In a second situation, rotating part drives first along clockwise direction, then detect switch 160 closed after, this is rotated in small angle range and continues, and then home position is got back in reversion.

Should be understood that these two retraction degree of sliding part not only allow to produce the jump with different jump orientations, and allow the shooting carrying out there is different power.

Certainly, the present invention is limited to the described and embodiment illustrated never in any form, but those skilled in the art should be able to make many changes and change.Especially, should be understood that by providing the extra lobes relevant with corresponding ratchet on arm 130, with different degree equipment sliding part, then for toy provides different holding position, and can then provide different jump orientations.
