Description
Technical field
The present invention relates to a kind ofly in relative both sides, have the skidding utensil of paired wheel, like four-wheel roller skate, slide plate etc. are utensil similarly.Particularly relate to a kind of skidding utensil that strengthens its steering response.
Background technology
In the industry, strengthen its steering response at present, proposed the design of many " canting can turn to " in order to make skidding utensil with paired parallel wheel.These structures normally are designed to the base and the wheel shaft of utensil: when the skidding utensil tilts to a side or opposite side, make two pairs of parallel pulleys turn to simultaneously.In four-wheel roller skate, slide plate industry, an example of the most generally knowing is exactly at United States Patent (USP) (U.S.Pat.No.3,442,523) a kind of roller skate that is disclosed in, it is the conventional roller skate with two pairs of wheels, the every pair of wheel all has a wheel rack device, include the pivot of an inclination and a paired wheel public wheel shaft.When roller skate during to lopsidedness, the rotation of roller skate base head lamp brush guard pivot makes the rotating shaft of wheel rack device rotate, thereby make the public wheel shaft of each root, with paired wheel above it and their annex, producing is turning to of level basically, therefore makes roller skate strengthen the steering response in the practicality.The conventional steering mechanism that slide plate had also works usually in the same way.
One of shortcoming of this design is to be unfavorable for the wheel that uses diameter bigger than conventional wheel usually.Require using reason than the major diameter wheel is that wish can be on rugged road surface, like earth, cobblestone, has on the road surfaces such as cement of ditch seam and also can slide reposefully.In general, all device is below base for the wheel of various sizes, and whole wheel will be lower than the height of base.Bigger wheel requires have higher base, center of gravity to uprise may cause the instability that slides.One of way of avoiding is with the periphery of wheel arrangement at base, reduces the height of base.Yet base may disturb the motion of mounting and wheel.For example, when the end of wheel arrangement, can touch with base because its range of movement is big at rotatable mounting.When using larger wheels, this situation may take place especially.For fear of the problems referred to above, wheel, mounting and/or base have been proposed various improvement, but all can sacrifice the succinct and convenient of product.For example, wheel arrangement must to reduce the possibility of colliding with base, still can be caused the increase of skidding instrument size, thereby reduce its portability away from base.
Also a kind of I participate in the sliding device capable of steering (U.S.Pat.No.7,306,240) of design, though preferentially be embodied on the skating shoe product of Inline Motoracing, also can be used for the scheme of four-wheel roller skate.The characteristics of the sliding device capable of steering that this patent proposes just are, vertical range between two parallel wheels and the vertical range between single wheel and the ice skate center line come down to remain unchanged in steering procedure.Even two wheels be provided with very close to, they do not have the danger of physical impacts yet when turning to.
The design of patent of the present invention is the periphery that wheel is arranged on base, wheel is separated, thereby can be reached above-mentioned similar result.Yet design of the present invention because of its frame for movement is comparatively simple, can be applicable to four-wheel skidding utensil better.
In addition, the skidding utensil wishes to use the bigger wheel of diameter than wheel at present commonly used, to strengthen its steering response.Market is a kind of skidding utensil smaller and more exquisite, light and simple in structure of demand also.
Summary of the invention
The present invention promotes the development of roller skate and slide plate product in order to overcome the shortcoming of current techniques, has proposed the skidding utensil that a kind of canting can turn to.This skidding utensil with extremely strong steering capability also provides and has used than the conventional wheel size potentiality of larger wheels more.
The skidding utensil that a kind of canting proposed by the invention can turn to (as ice skate or slide plate) is that it has a wheel assembly that can turn at least, and this assembly contains by two two wheels that wheel shaft supported that tilt mutually.These two wheels become down " V " font to tilt mutually when non-steering position, and the wheel shaft of two wheels is vertical substantially with direct of travel, and they itself can rotate around horizontally disposed rotating shaft again.
The skidding utensil that another kind of canting proposed by the invention can turn to (as ice skate or slide plate), it has a wheel assembly that can turn at least, and this assembly contains by two two wheels that wheel shaft supported that tilt mutually.These two wheels become down " V " font to tilt mutually, and each wheel shaft is again a rotating part on the base rotary crankshaft.Except two wheel shafts tilt mutually, also can obtain compensation and make wheel maintenance level from the base bent axle.When the skidding utensil tilted to a side or opposite side, the inherent characteristic of this structure will make the skidding utensil produce and turn to.
Experienced insider is in conjunction with drawing, investigated following detailed after, should be able to understand relevant advantage that utensil of the present invention had and characteristic more.

The specific embodiment
Consult Fig. 1, about the general assembly stereogram of a kind of skidding utensil 100 proposed by the invention.Skidding utensil 100 has the front component 120 that can turn to, and the wheel assembly 130 that can turn to.These assemblies provide the characteristic of the go to action that relies on canting and produce.The front component 120 that can turn to comprises wheel 121 and wheel 122, and they connect with bent axle 123,124 lotus roots respectively; The wheel assembly 130 that can turn to comprises wheel 131 and wheel 132, and they connect with bent axle 133,134 lotus roots respectively.Bent axle 123,124,133,134 again with base 110 rotationally lotus root connect.Base 110 can constitute with various materials (plastics, metal etc.), and can make diversified form.
Consult Fig. 2, about a skidding utensil 100 proposed by the invention, the stereogram after its wheel 121 disassembles from wheel shaft.Skidding utensil 100 has the front component 120 that can turn to, and it comprises wheel 121 and bent axle 123.Bent axle 123 has comprised: with base 110 base shaft 125 that connects of lotus root rotationally; The wheel shaft 126 that connects with wheel 121 lotus roots; And the intermediate connecting rod 127 that base shaft 125 is connected with wheel shaft 126.When the position that does not turn to, wheel shaft 126 up, the first half of wheel 121 tilts to the inside.Because the wheel shaft 126 on both sides is all not parallel with base shaft 125 separately, the first half of wheel 122 also tilts to the inside, makes paired wheel 121 and 122 one-tenths (can be clearly from Fig. 3 on as seen) of falling the mutual inclination of " V " font.When this kind position, wheel shaft 126 can keep balance with base shaft 125.Wheel shaft 126 on the front component 120 that can turn to will compensate forward in the hope of balance, and the wheel shaft 126 on the wheel assembly 130 that can turn to will compensate backward in the hope of balance.Angle of inclination and above-mentioned compensation have caused between base shaft 125 and the wheel shaft 126 different on the orientation, cause the axis of each wheel shaft 126 and the axis of each base shaft 125, not in one plane.
On each wheel 121,122,131,132, on one side a cavity is set all near the connecting rod 127 of bent axle 123,124,133,134, bent axle can be contained at least in part the inside of wheel separately, thereby can reduce the integral width of skidding utensil 100.As seen, a side of close bent axle on wheel 121,122,131,132 is because dwindling of spoke caused the cavity that holds bent axle on Fig. 2.Certainly, in other embodiment, also can adopt multiple multi-form cavity.
Consult Fig. 3,4,5, they are respectively about skidding utensil 100 of the present invention, the front view under non-steering state, stereogram and vertical view, (three pictures are for the ease of comparing together).When non-steering state, power (person's of typically using body weight) roughly is to be distributed in equably on two wheels 121,122 of the front component 120 that can turn to.Wheel 121,122 is deflection to the left or to the right not, so skidding utensil 100 continues to advance forward.
Consult Fig. 6,7,8, they are respectively about skidding utensil 100 of the present invention, turn left to the time front view, stereogram and vertical view.When base 110 cantings on one side or during another side, just begin to turn to.Because two wheels on the front component 120 connect with bent axle 123,124 lotus roots, each wheel can rotate (see figure 2) by means of separately base shaft 125, so the canting of base 110, bent axle 123,124 will rotate, will keep contacting of all wheels and ground.When base 110 canting left, the rotation of bent axle 123 causes wheel shaft 126 (so that is being wheel 121) to turn to, after shifting to.The direction of wheel shaft 126 is compared with the direction of the wheel shaft 126 shown in Fig. 3~5, is to have changed direction.Further increase in order to reduce canting, make wheel shaft 126 make progress, rotate backward.Because wheel 121 is orthogonal with wheel shaft 126, so wheel 121 also has been tilted to the left.
When base 110 canting to the right, though the suffered power of wheel 121,122 can produce similar effect with above-mentioned opposite.Therefore the direction of canting changes, and can make the direction of skidding utensil 100 switched in opposite.
At the another side of the wheel assembly 120 that can turn to, similarly process is taking place, cause the inclination of wheel 122.Because the unequal distribution of power in the canting process, when bent axle 123 when a direction is rotated, bent axle 124 rotates in the opposite direction; Because when non-steering position, wheel 121 is that rightabout tilts (producing reverse inclination angle) with wheel 122 again, and the canting of base 110 makes two wheels with inclined, makes the directional steering of skidding utensil 100 towards canting.
In this programme, also be provided with the wheel assembly 130 that can turn to.In fact, the wheel assembly 130 that can turn to is similar to the front component 120 that can turn to, but is oppositely to place, that is replaces with the wheel shaft 126 that is offset backward and to be offset wheel shaft 126 forward.This just makes and wheel 131 and wheel 132 in the process that turns to, tilts towards the direction opposite with base 110 tilted orientation.The direction of rotation of the rotation direction of the front component 120 that can turn to and the wheel assembly 130 that can turn to has strengthened the whole steering capability that skidding utensil 100 can turn to small radii.
Consult Fig. 9, it be the skidding utensil when turning to, the two cover wheel assemblies that can turn to are with the stereogram of connecting rod transmission scheme (for clarity, do not draw base 110).The wheel assembly 120,130 that every cover can turn to preferably will have a bindiny mechanism 200, with two wheels that guarantee to link to each other with the same wheel assembly that turns to, in fact stands angle same and changes.As shown in the figure, bindiny mechanism 200 includes the connection pivot 210 that stretches out from base; With the base shaft 125 prominent bar 220,221 in the location that connects of lotus root mutually; And in fact with vertical angle and bindiny mechanism 200 connecting rod 230 that connects of lotus root mutually.Location prominent bar the 220, the 221st is drawn close mutually with connecting rod 230.
When turning to, the rotation of base shaft 125 along with the increase of dynamics, causes that first prominent bar 220 in location presses to the associated end (first end) of connecting rod 230.Connecting rod 230 drives the rotation that connects pivot 210, and second end of connecting rod 230 exerted pressure to second prominent bar 221 in location, and makes it to rotate.Though direction is opposite, the distance that it rotates is actually the rotation distance that equals to locate prominent bar 220.Therefore, bent axle 123,124 with mutual opposite direction, similarly rotates in fact angle same separately, and wheel 121,122 just produces with practically identical direction.
Consult Figure 10, it be the skidding utensil when turning to, the two cover wheel assemblies that can turn to are with the stereogram of pulley transmission scheme.(for clarity, do not draw base 110).The wheel assembly 120,130 that every cover can turn to can have a bindiny mechanism 300, with two wheels that guarantee to link to each other with the same wheel assembly that turns to, in fact stands angle same and changes.As shown in the figure, bindiny mechanism 300 includes pulley 310, and the connection cable 320 that links to each other with pulley 310.Bent axle 123,124 separately with bobbin 330,331 mutually lotus root connect.One end of connection cable 320 is on bobbin 330, and the other end is on bobbin 331.When a bent axle during, connection cable 320 is wrapped on the corresponding bobbin further, and the connection cable 320 on another bobbin take off out through pulleys 310 pines, so another bent axle has just rotated in the opposite direction towards the rotation of some directions.
Consult Figure 11, it be the skidding utensil when turning to, the two cover wheel assemblies that can turn to are with the stereogram of gear drive scheme.(for clarity, do not draw base 110).The wheel assembly 120,130 that every cover can turn to can have a bindiny mechanism 400, with two wheels that guarantee to link to each other with the same wheel assembly that turns to, in fact stands angle same and changes.As shown in the figure, bindiny mechanism 400 includes and connects gear 410,411, and they are engaged with each other.Bent axle 123,124 separately with shaft gear 420,421 mutually lotus root connect, respectively be connected gear 410,411 and be meshed.When a bent axle during towards the rotation of some directions, by shaft gear 420,421 and the transmission that is connected gear 410,411, so another bent axle has just rotated in the opposite direction.
It is to be noted that especially the scheme that the roller skate canting can be made it to turn to proposed by the invention can be used to design the product of slide plate equally, and also can both use diameter greater than 100 millimeters wheel.Base can be connected with the platform of a carrying user boots, and then also comprises the pin of guaranteeing the user and stand in measure on the platform and the structure that supports user's ankle-joint.Certainly base also can directly be connected with boots; Or directly be connected with seat.
It is worthy of note that also this paper has only narrated connecting rod transmission scheme, pulley transmission scheme and gear drive scheme to bindiny mechanism.Obviously, the connection between the wheel can also realize with the NM mode of the present invention.Should be noted also that also and can use (all not drawing in the above-mentioned view) a kind of resetting-mechanism or multiple resetting-mechanism, under the effect of resetting-mechanism, the position when wheel can trend towards being returned to original non-turning to.When skidding utensil 100 was lifted from ground, the wheel assembly that can turn to thereby can return to the non-form that turns to, each wheel position during all with non-turning to contacted with ground.Practical reposition element (spring, elastic ribbon, the gentle bar of elasticity etc.) and annex thereof can be by putting on a plurality of possible positions, near bindiny mechanism, or near the bent axle.In addition, a braking or braking mechanism can also be set, where necessary, be used to make the rotation of wheel.
The material that is used to make roller skate is known by the insider.Shoes can be used leather, plastic or other material; Base or support available metal, plastics or other material (particularly character in light weight, that intensity is big will be arranged) that is fit to; Wheel can be made with materials such as rubber, polyamine fat.
Though abovely the present invention has been made description, has been construed as the present invention and can also does further change by several specific embodiments.This patent is intended to contain various variations, purposes or the improvement of carrying out according to principle of the present invention.Also contained with disclosed known arrangement or enforcement convention and departed to some extent, but still be subordinated to the scope of the technology of the present invention and application principle thereof.This patent has also been contained the scope of claims of the present invention.
