The visual angle of Fig. 5 is to be positioned at this slide plate 10 the place aheads, and these pivots 34, the 50th, a certain position intersects on this platform 12, and describe as side view Fig. 2 of this slide plate 10, this each roll wheel assembly 24,26 all with can be with respect to its pivot 34, the mode of 50 beats is installed, and these pivots 34,50 extension line all can form an acute angle T1 with this platform 12, T2, when this slide plate 10 towards with the rightabout torsional deformation of Fig. 5 the time, these take turns the rotation of part 36 with respect to its rotating shaft 40, be can be in conjunction with these roll wheel assemblies 24,26 slip beats with respect to its pivot 34,50, and can cause, keep or quicken moving forward of this slide plate 10, this is because these pivots 34,50 angle tilts, and makes these roll wheel assemblies 24,26 be positioned at its pivot 34, the rear of 50 extension lines and this platform 12 intersection points causes, that is, the pivot 34 of each roll wheel assembly 24,26,50 all tilt in the same direction, these pivot 34,50 suggestions are tilted towards the direction of advance of this slide plate 10, or towards tilting with this parallel or approximately parallel direction of advancing.

Now see also Fig. 6, shown forward and backward transverse axis 13 among the figure, the 15th, be positioned at opposite location with Fig. 5, this be because the user with the pin reverse rotation, that is the user depresses or mentions the front and rear portions 18 of this slide plate 10 with the direction opposite with Fig. 5,20 institutes cause, yet because these pivots 34,50th, stretch on the position on the edge that is positioned at these slide plate 10 directions of advance, therefore these rotations of taking turns part 36 are the onward impulses that can increase this slide plate 10 in conjunction with the beat of these roll wheel assemblies 24,26.

Now see also Fig. 7, solid line among the figure is to be shown in this slide plate 10 to carry out in the process as Fig. 5 or Fig. 6 torsional deformation, its anterior 18 left side edge points 74 are situation over time, this marginal point 74 can be regarded as the crosspoint 74 of this preceding transverse axis 13 and these platform 12 left side edge, in a certain specific time point for example during t0, this marginal point 74 is to be positioned at rotation initial point (zeropoint), and when the left side of this front portion 18 is rotated down by user's application of force, this marginal point 74 also will rotate down, arrive maximum and make this marginal point 74 up to the active force that the user applied in another specific time point, promptly as t1, arrive till the minimum position of rotation, subsequently, as user during to the reaction force attenuation of this front portion 18, the anglec of rotation of this marginal point 74 also will reduce gradually, arrive t2 up to the time, and this marginal point 74 is got back to till the anglec of rotation is this rotation initial point of 0 °.

Subsequently, user's downward pressure will put on the right side edge of these 18 front foot Support 14, front portion, thereby make the marginal point 74 in its left side be twisted or rotate up, and then arrive a maximum application of force and the time point t3 of high position of rotation, subsequently, this this active force successively decreases gradually again, revert to the rotation initial point when the t4 time point again up to its position; Also can be as shown in the dotted line of Fig. 7, the user also can similarly force in this rear portion 20 in the opposite direction, the feasible neutral position of marginal point 76 when t0 that is positioned at this metapedes Support 16, maximum when rotating to t1 rotates up angle, when t3, arrive the angle that is rotated down of a maximum again, then get back to the rotation initial point once more in t4.

Now see also Fig. 8, by user's apply in order to reverse amount of force to special angle, should be relevant to the controlled quentity controlled variable of this slide plate 10 with the user, relationship change between strength and rotation amount depends on that rotation amount or strength size are expected, for example, for reaching the slide plate design of a non-sensitivity (stiff), that is allow twisting and when need not back stretch with large scale, the shape of this platform 12 can be designed to, the user is relatively large near the required strength of this slide plate of the twisting neutral surface 17 10, but when each position of this slide plate 10 has been passed through a special angle, even make it continue to keep the extra application of force of rotational deformation, also should be less relatively concerning the user, in addition, based on further security and operability are considered, thereafter the user reaches the required extra application of force of the maximum anglec of rotation should rise rapidly, as shown in Figure 8, the size of its application of force is identical when situation is with drafting Fig. 7 over time, but marginal point 74 among the figure, 76 different between the two variation figures can provide the user different operation feeling.

Now see also Fig. 9, the above-mentioned notion of discussing can be as shown in this figure, wherein the required application of force size of user is to decide with rotation amount, the user is to the operation feeling of a slide plate 10, be not simple to describing by the mathematical function of the application of force or the anglec of rotation, some had given shape, front and rear part 18,20 and mesozone 22 have particular kind of relationship, with and sidewall, rib, surface amplitude and other factor have the particular design slide plate platform of given shape and size, the own cover of user is known from experience the mode of its operation feeling, that is the operation feeling of this slide plate 10 and user are to these slide plate 10 conspicuous controls, in present embodiment shape and other structural parameters that depend on this slide plate 10, for the simplification on describing, one special skateboard can be regarded as having one " linearity " operation feeling, that is, the interaction of user and this slide plate is concerning the user, can cause the applied force amount and the anglec of rotation of being reached to reach a linear relationship, in fact, this operation feeling is very subjective but still is real, though actual mathematical relationship may not be linear, line segment 78 among the figure can be used as a relevant example, be linear or other kind of expression, and have the slide plate of one first structure platform.

The shape of this platform 12 and structure can be adjusted, for example can be by reducing the length of this mesozone 22 along this major axis 28, or before changing this mesozone 22 and being somebody's turn to do, rear portion 18, the tapering of 20 transition regions, platform 12 for some special constructions, the relative length of this narrower mesozone 22 of extending will cause wayward this slide plate 10 of user, and the relative length that shortens this mesozone 22 can cause reaching of any anglec of rotation all to become comparatively difficult, before similarly influence also can be somebody's turn to do by 22 pairs of this mesozones of adjustment, rear portion 18,20 relative width is reached, line segment 80 among the figure has promptly shown expected control relation between strength that the slide plate of a particular design is required and the angle of being reached, more specific example that change with application of force size about the twisting amount can be with reference to following Figure 14 A or Figure 14 B, and these embodiment can consult Figure 14 to Figure 19 in the lump.

Importantly, but this one chip platform 12 is by the made advantage of the plastic material of torsional deformation, these slide plate 10 required operation sense or controls can be reached by the device again of this one chip platform 12, though be difficult to prediction (by the precision of mathematics), but the shape of this platform 12 and structure all need reach a desired operation feeling, yet, thereby by revising shape and the structure that its mold changes this platform 12 repeatedly, so that it is possible forming a satisfied design with proper handling sensation, especially, the rotation amount that the size of the strength that applies and this slide plate 10 are reached and the relation of torsional deformation amount are with these platform 12 width, shape and other CONSTRUCTED SPECIFICATION and different.

This platform 12 is to combine in one piece or by bent PU elastomeric material, nylon (nylon) or other rigid plastics, and can mix fiber to strengthen its structure and further to control its flexible and operation feeling.

Now see also Figure 10, this is the stereogram of these one chip platform 12 bottom sides, and be to show that one or more wedge 82 is installed in the larboard wall portion 52 of this sidewall 62, starboard wall portion 54 and transverse part 56 are inner or therebetween, these wedge 82 suggestions can be made by elastomeric material, and be in order to reduce the distortion elasticity of this mesozone 22, for instance, it can hinder this left side, starboard wall portion 52,54 carry out torsional deformation, in present embodiment, these wedges 82 are to fill in these left sides tightly, starboard wall portion 52,54 or transverse part 56 between or utilize bolt or folder to fix, and be located at this platform 12 mesozones 22 removably, the installing of these wedges 82 with remove the elastic characteristic that will change this platform, thereby change its operation feeling and operability, for example, can install these wedges 82 when the beginner uses, and be removable subsequently so that do wider control.

Now see also Figure 11, it is the partial view that aligns structure for these one piece flexible skateboard 10 front portions 84 automatically, and be to show that its roll wheel assembly 86 is to be installed in hollow and to be formed on the wedge 88 of 90 belows, front foot Support, among the figure only the visible bolt 92 that penetrates of head are the interior rings that pass a steering bearing 94, the bottom surface of one bearing holder (housing, cover) 95 and a wedge 88, and mesh with a nut (figure does not show), this penetrates bolt 92 is the inside that is penetrated these wedge 88 hollows by the top of these slide plate 10 platforms 12, the outer shroud of this steering bearing 94 is the forks 96 that are fixedly arranged on this roll wheel assembly 86, and installing by this steering bearing 94, this fork 96 is to carry out relative the rotation with this bearing holder (housing, cover) 95, make roll wheel assembly 86 integral body to rotate with respect to this pivot (i.e. pivot 50 as shown in Figure 2) that penetrates bolt 92, this penetrate bolt 92 can be used as with respect to installing place on the slide plate 10 the axle part 41, and axial bolts 98 is elongated end 100 roll wheel assemblies 102 that are arranged in this fork 96, and makes this take turns part 104 can to rotate.

In present embodiment, one elasticity acting device is to be located between a certain fixed position on this roll wheel assembly 86 and this platform 12 (or on this roll wheel assembly 86 a certain position of being fixed in platform and not moving), so that control the rotation of this fork 96, to increase the rotational resistance of this roll wheel assembly 86 with respect to this pivot 34, this resistance size is to decide on these roll wheel assembly 86 rotation amplitudes, and this roll wheel assembly 86 is aligned automatically, the kenel that this roll wheel assembly 86 aligns automatically, can make this take turns part 104 and move apart this slide plate 10 when user's weight, when for example carrying out the grandstand play of single-wheel support, has the tendency of aiming at this major axis 28 (seeing Fig. 1), this roll wheel assembly 86 if do not possess this elasticity acting device automatically to orthofunction, when carrying out single-wheel support performance, this roll wheel assembly 86 will have relatively, and this penetrates the tendency of bolt 92 rotations, thereby finish and should the wheel part 104 when contacting when this single-wheel support part with ground, this roll wheel assembly 86 will can not move towards the direct of travel of aiming at this slide plate 12, by this, particularly when doing the fancy performance, automatically the operating characteristic that can improve this slide plate 10 to orthofunction of this roll wheel assembly 86, action for wheel part 104 kiss the earths, similarly be to move or rotate, this elasticity acting device can freely be set has the resistance that can experience, or the resistance that can experience of tool not, it need be decided on the relation between application of force size and platform 12 torsional deformation amounts.

See also Figure 11, between fork 96 (or other be positioned on the roll wheel assembly 86 and can penetrate the position of the axle center rotation of bolt 92) and the front portion 84 (or on other this platform 12 fixed position) that this roll wheel assembly 86 can be by being installed in spiral spring 106 on platform 12, and has the function that aligns automatically for this.

Now see also Figure 12, it is the part top view that shows this roll wheel assembly 86, this roll wheel assembly 86 includes a bearing holder (housing, cover) 95 (it is to be fixedly arranged on platform 12 by penetrating bolt 92) and a fork 96 (it is installing with respect to the mode of the pivot 50 that penetrates bolt 92), in present embodiment, this roll wheel assembly 86 also can pass through a torque spring to orthofunction automatically, for example helix torsion spring 106 is reached, the stiff end of this torque spring 106 is to be fixed in actionless part on this slide plate 10, for example this bearing holder (housing, cover) 95 or and platform 12, a slit then can be filled in the mobile terminal of this torque spring 106, the indentation 108 of this fork 96 for example, and be installed in can roll wheel assembly 86 with respect to these pivot 50 beats on.

Now see also Figure 13, it is that show can be for the cutaway view of base 11 structures of these pivot 50 rotations, wherein, one low frictional torque bearing 110 is to be located between bearing holder (housing, cover) 95 and fork 96 end faces, low frictional torque bearing 110 can be a solids, Teflon (Telfon) for example, or be a liquid, the lubricating fluid that uses for general bearing for example, or can use both simultaneously, in addition, this low frictional torque bearing 110 also can only be between an open space or the depression of bearing holder (housing, cover) 95 with fork 96 top sides, and can make this fork 96 fully be supported in this steering bearing 94 (seeing Figure 11) in the mode of this bearing holder (housing, cover) 95 of noncontact, in any case but, around this penetrates bolt 92 and between this fork 96 and this bearing holder (housing, cover) 95, open region as depression 112, be can be for torque spring 114 installings that this roll wheel assembly 86 is aligned automatically, especially, torque spring 114 can comprise central portion 116 as a spiral winding and a stiff end 118, this stiff end 118 is with relevant with respect to the rotation of this pivot 50, and the mode that can pass bearing 110 inside is installed, if with regard to present embodiment, it is to pass this bearing holder (housing, cover) 95 or pass this to penetrate bolt 92, this torque spring 114 hold 120 to be to be fixedly arranged on the roll wheel assembly 86 that can rotate with respect to this pivot 50 in addition, for example be fixedly arranged on the fork 96 of this roll wheel assembly 86.

Now see also Figure 14 A to Figure 14 C, should be noted that, but have the torsional deformation platform 12 of one chip and the slide plate 10 of spring capable of automatic aligning 106, still having may be than not adorning the more difficult operation of the slide plate that aligns spring automatically, particularly this aligns spring automatically and also may suppress or limit its beat function, and this beat function can be improved and drives sensation, but Figure 14 A and Figure 14 B are the variation diagram of one group of user for application of force size with the slide plate torsional deformation angle of torsional deformation platform 12, before transverse axis 119 among the figure shows that the user is with this broad, portion 18,20 towards the different directions application of force to reverse the increase application of force (increasingforce) of this platform 12, the mid point of transverse axis 119 is not situations of the application of force of demonstration one, and two outer ends of this transverse axis 119 are to show that the user applies and with so that before this, back 18, the 20 maximum application of forces of reversing in the opposite direction, the longitudinal axis 122 are the torsional deformation angles that show these platform 12 ends.

Now see also Figure 14 A, line segment 124 among the figure is to show the variation situation of user's application of force size to the non-bent one chip slide plate 10 terminal torsional deformation angles of tradition, on the initial point 126 in the drawings, even in fact the user has the application of force of carrying out, but because the mutual balance of these application of forces, therefore do not produce any rotation distortion, for traditional slide plate, user's off-centre is exerted pressure and will can not, perhaps seldom make it carry out the relative twisting of end-to-end (end to end), the finite elasticity of conventional skateboard, if the words that have, perhaps produce end-to-end the reversing about 5 ° at most only, flexibility that these are limited or torsional deformation possibility perhaps can help to absorb collision or vibration from ground on one's body in conventional skateboard, and can lower stress or the bump of bestowing user's foot, but this limited torsional deformation will be not enough to provide substantial advance mobile, or the advantage that other flexible skateboard had, that is, even the user carries out the rightabout application of force respectively at one first state (for example clockwise) and one second state (for example counterclockwise) of this slide plate repeatedly for several times, the limited end-to-end twisting of this slide plate still deficiency so that roll wheel assembly (if the words of use are arranged) provides any slide plate mobile trend with respect to its pivoting angle.

Line segment 124 conveniently is to show with linear fashion for asking drawing, and the size of its end-to-end torsional deformation angle of some slide plate and the eccentric application of force is linear, yet, with regard to other slide plate, its relation may be a curve for example for non-linear, similarly is a smoothed curve.

Now see also Figure 14 B, line segment 128 is the pressure reduction that bent one chip slide plate 10 applied with the user for the torsional deformation angle or the variation situation of power poor (differential pressure orforce), pressure reduction wherein or power difference can be the user by major axis 28 both sides being applied the unequal application of force that platform is reversed, as this figure as can be known, the relation of this power difference and one piece flexible skateboard torsional deformation angle may be for linear or non-linear, near initial point 126 core forms one first scope 130, first scope is a traditional operation district (Conventional Operation Zone) 130, in this district, user's the pressure reduction that is applied can't produce is enough to end-to-end twisting that slide plate is moved; The width in traditional operation district 130 is shown, is for bestowing the power difference differential pressure of slide plate 10, for example by a pin slide plate is clockwise rotated and another pin rotates counterclockwise slide plate, at the maximum magnitude that does not make this slide plate with bent formal operations.

If the power difference of this maximum or torque forces (perhaps can't make a flexible skateboard start) can make the user experience feedback (feedback) or resistance from slide plate, it is smooth that the user can make this slide plate keep more easily, that is, do not operate to make its mode that turns to as the operation with traditional slide plate; On the contrary, if slide plate can be easily for these initial point 126 bendings, make the user can't differentiate slide plate when torsional deformation or when non-warping distortion easily by feel, the user just must adjust the pressure reduction that slide plate applied continuously, just can make slide plate to be same as traditional mode straight ahead; If this pressure difference is positioned at reduced levels, though that is its value can produce the essence torsional deformation, not even as big as be used note or control before, this pressure difference can be regarded as dead point (dead point), at this moment, even only attempt to make slide plate keep straight ahead, it is tired also the user to be produced; Yet if shown in line segment 128, if the value (degree of its end-to-end twisting is not enough to make skateboard turns) of pressure reduction is enough high, the user can experience from the resistance of slide plate or feedback, and this slide plate can be manipulated into straight ahead easily, and can not cause substantial tired to the user.

In other words, it is necessary providing sufficient twisting resistance itself to slide plate, thus, even when this pressure reduction is low, the user still can experience resistance by its both feet, so that this slide plate straight ahead or only turn to by tilting, and when this slide plate was considered as the non-bent or smooth slide plate of tradition and operates, institute produced tired or stress when reducing the operation slide plate; By applying bigger power difference or torque forces, rotational energy can put on the wheel part, and is poor by applying power again and again again, so that the end-to-end torsional deformation that surmounts this traditional operation district 130 to be provided, slide plate is moved or to turn to.

Now see also Figure 14 C, another important viewpoint about this slide plate torsional deformation is, be positioned at this slide plate 10 sufficient Support 14, the twisting amount of 16 material should drop to minimum, so that minimizing user's stress and tired, for instance, if this forward and backward sufficient Support 14,16 torsional deformation amount is enough high, and then this twisting will influence the vertical angle at user's ankle support place; In the process of these slide plate 10 material torsional deformations, moving of user's heel and toe also will cause the torsional deformation of user foot; If each sufficient Support 14,16 are twisted to reaching the high position, the user also will change with twisting in order to the angle of the ankle of support shank, for instance, the torsional deformation of supposing this slide plate 10 only appears at this mesozone 22, though user's ankle can rotate and knee meeting bending front and back, but each foot support district all can be considered the user is supported on the vertical plane, yet, if the torsional deformation that showing also appears in sufficient Support 14,16, for instance, if when the vertical support face that user's shank was positioned at when not twisting because of twisting exceeds was outer, this slide plate was operated in the twisting process and will be made the user cause the bigger application of force and tired.

Yet, in each sufficient Support 14, a small amount of twisting of 16 is an acceptable, for drawing conveniently, user's shoes 19 shown persons are positioned on the front portion 18 of slide plate 10 line segments 21, and the twisting angle shown in the figure is that section 21 along the line is extended and away from this initial point 126, this initial point 126 is that of this slide plate 10 of hypothesis is positioned at mesozone 22, even and when this slide plate 10 is twisted to maximum (for example 50 °), the point that also still can not rotate; Will be with respect to the anglec of rotation of this major axis 28 along with increasing away from this initial point 126, then reach maximum as 22.5 ° in contiguous these mesozone 22 ends; For reducing user's stress and tired, shank vertical support more than user's ankle (shown in dotted line 25), and the position that is caused by the material twisting that betides platform 12 front foot Support 18 changes, and will be reduced to a small amount of value angle of a contiguous vertical support line 27.

Please return Fig. 2, this sidewall 62 can be arc owing to being bent into of these slide plate 10 surfaces 58, and minimizing user's stress and tired, if the material of this slide plate 10 more easily bends, or for example can't provide enough support preventing bending by sidewall or its analog, if the user stand the outside and during too away from the Support of roll wheel assembly 24,26, because its foot outside is with downward-sloping, so user's ankle 23 will suffer stress; Similarly, if the user stands too inboardly and during away from the supporting zone of roll wheel assembly 24,26, its ankle is also similarly because foot inboard downward-sloping and need meeting with stresses; The user's foot inclined visible that is caused by the bending of slide plate 10 materials is for roughly to betide on the plane of passing through user's human body width, and similarly stress also may occur in when excessive stress and put on this forward and backward sufficient Support 18,20 o'clock; These stress be that foot support place by the user too departs from this vertical plane and caused; Than mesozone 22 is forward and backward sufficient Support 18,20 of wide this promptly as the sidewall 62 that increases of co-altitude, can be in order to reduction user's stress and tired; For constructional convenience, when the user's foot stress that is produced by the excessive twisting in foot support district can be thought of as a twisting degree up and down when front side inside and outside user's foot and is higher than the foot rear side, the torsional deformation of user's foot.

Now see also Figure 15 (together with Fig. 1, Fig. 2 and Figure 11), it is the top view that shows this forward and backward roll wheel assembly 24,26, and is the major axis 28 of aiming at slide plate 10 platforms 12; Especially in this roll wheel assembly 26, the interior ring 132 of this steering bearing 94 is to be located on the slide plate as platform 12 fixed parts, and its outer shroud 134 is to support fork 96, and but fork 96 is to take turns part 36 for this to set firmly thereon in the mode that phase countershaft 40 rotates, the direct of travel that this castor assembly 26 is rotated is vertical this axle, and shown in vector 140.

The typical shape of this bearing 94 is circular, but this figure is a top view, and outer shroud 134 is to use for being rotated with respect to axle 50, because this pivot 50 is not perpendicular to platform 12 end faces 58, but form an acute angle T2 as Fig. 2, this steering bearing 94 is perpendicular to pivot 50 in the plane shown in the figure, so present ellipse, in being somebody's turn to do, outer shroud 132,134 summit T and end point B indicate for ease of the direction that this roll wheel assembly 26 is discussed, especially, inside may be to install in its thicker part mode forward for hollow wedge-shaped piece 48, and because the angle of strike T2 of this 50 acute angle, make the summit T of ring 132 in this comparatively near this end face 58, some B is then further from this end face 58 at the end of interior ring 132.

This outer shroud 134 will be aligned spring 106 (as shown in figure 11) automatically by this with respect to this beat scope of 50 and limit, this steering bearing 94 is to be installed in this end face 58 by this wedge 48 to form on the plane of an angle, and the tendency that the rotation of allowing is arranged, therefore, the summit T of this inner and outer rings 132 and the end point B be capable of automatic aligning.

In Figure 15, the user just along this major axis 28 application of force Ff138 and Fr136 (respectively at preceding, metapedes Support 14,16), this is not have the institute that applies of any power difference to cause, so the platform 12 of this slide plate 10 does not produce the end-to-end torsional deformation of essence, in fact, if platform 12 is relatively low for the resistance of torsional deformation, just low to the resistance that is difficult to experience as the user from platform 12, the user then must move with the non-rectilinear of responding this slide plate by the pressure reduction that applies different values, this continual mode of operation is not seen by happy, because it will cause tired and stress, be expected at one piece flexible skateboard so keep MIN twisting resistance.

The roll wheel assembly 24 that Figure 15 is shown, 26 is haply on same direction, unless it is preceding, the rear foot is exerted pressure or the application of force from the rightabout of this major axis 28, now see also Figure 16, among present embodiment, this platform 12 is to have enough anti-twist resistances, make the user to apply a little pressure reduction at least to this platform 12 easily, and do not cause these roll wheel assemblies 24,26 off-straight advance routes, that is, before this, rear wheel 36 can be kept haply along this major axis 28 and advance, during the feedback force that obtains to produce because of the anti-twist resistance of slide plate even make the user apply enough pressure reduction, this slide plate is still operationally as the non-bent slide plate of tradition; As aim at shown in the motion-vector 140 of this major axis 28, this slide plate 10 is linearly to advance, that is operate ground as the non-bent slide plate of tradition, even there is a little pressure reduction also together, the anti-twist resistance of this higher degree is expected for reducing user's effect tired or stress.

Now see also Figure 17, the user is just applying average in fact pressure, shown in Fr 136 and Ff138, and this platform 12 is tilted, therefore, roll wheel assembly 26, in 24 bearings 94, outer shroud 132,134 summit T and end point B are in this application of force 136, under 138, will and present displacement towards this rightabout of 28 inclination, by this, this application of force will make this roll wheel assembly 24, rotatable position is rotated with respect to its pivot on 26, so that make the summit T of outer shroud 134 and the end put summit T and the end point B that B aims at interior ring 132 as shown in figure, is to take turns part 36 to rotate the direction of advancing as for this 140 of straight line vector, because this vector 140 no longer is parallel to this major axis 28, so the direct of travel of this slide plate 10 will tend to advance towards direction vector 140 by advancing along major axis 20 to change into; Turning to by the average application of force produced in fact is to depend on many factors, comprises the shape of taking turns part 36, together with rocking and other factors, but can be used to produce turning to of part degree at least.

Described above, slide plate 10 function modes that turn to by the inclination of platform 12, it can be regarded as in the opereating specification of the non-flexible skateboard of tradition, that is, the user to the sensation of this slide plate can with to conventional skateboard feel similar, and what should be noted that is that employed wedge of traditional non-flexible skateboard and guide roller may typically be designed towards rightabout, make wheel thereafter be positioned at this trailing wheel the articulated section before, front-wheel then be positioned at front-wheel the articulated section after.

Now see also Figure 18, for relatively convenient, wheel part 36 is replaced with expression way designed in scheming, in this structure, two take turns part 36,142 pivot is not aligned with each other haply, that is this two pivot of taking turns part does not form a similar acute angle with respect to this platform 12, to the homonymy of this major axis 28 apply average exert pressure will cause front wheel assembly 24 wheel spare 36 as shown in the figure, rotate with first form (for example counterclockwise), then 142 of the wheel spares of roll wheel assembly 26 are with opposite form (for example clockwise) rotation, and turning to as shown in the figure is for counterclockwise, and along with front-wheel 24 moves.

Now see also Figure 19, use guide roller assembly 24,26 one piece flexible skateboard, be to turn to by applying pressure reduction, for example by putting on major axis 28 both sides, with so that guide roller assembly 24,26 the power difference Fff136 and the Ff138 of beat in the opposite direction, slide plate 10 is turned to or move; It should be noted that the inclination that applies power difference or torque forces and mating part degree, can successfully turn to by slide plate 10.

Now see also Figure 14 to Figure 19, in present embodiment, the anti-twist resistance of this platform 12 is sufficient, so can be by impose the rough equal average application of force of value respectively along these major axis 28 application of forces or in the both sides of this major axis 28, can make this slide plate 10 as Figure 15 and shown in Figure 16, operate in the mode of straight ahead; This slide plate 10 also can be similarly makes platform 12 tilt to turn to by both feet towards the homonymy application of force of this major axis 28, these three kinds of modes of operation can be regarded as the mode of operation as the traditional operation district 130 among Figure 14, that is, the mode of operation of this mode of operation and non-bent slide plate is same or similar, and shown in Figure 19 be to can be considered a kind of mode of operation that is positioned at beyond the traditional operation district 130, the torsional deformation of its platform 12 can make roll wheel assembly 24,26 towards the different directions beat, and this platform 12 also can tilt when torsional deformation.

The slide plate of this one chip can be formed by the winding of multi-disc plastic material, for example can pass through the nut and bolt winding, can be as being moulded by the plastic material one when making the slide plate twisting.

Now see also Figure 20, flexible skateboard 146 can be designed to have integrally formed wooden platform 148, promptly has the platform 148 of playing tail 150 as shown in FIG., playing tail 150 extends for the part of this wooden platform 148 and in the mode of crossing trailing wheel, so can the one pin playing on the tail 150 in this, the user exerts pressure, change the manifestation mode of this slide plate 146, for example by these slide plate 146 tail down are played kiss the earth so that slide plate stopped or changing direct of travel, wooden slide plate can be easily by through vacuum, the glued board of steam or other conventional process is made; Comprise this and play tail 150 interior, this wooden platform 12 all can be made into edge-to-edge's symmetric shape as shown in figure 21 easily.

Now consult Figure 21, it is to show the cutaway view of Figure 20 along A-A, the shape of this slide plate 146 is to be edge-to-edge's symmetry as shown in the figure, and this shape can form with this wooden platform 148, for example can play tail 150 places or form along the major axis of this platform 148 in this, the section configuration shown in the figure also comprises a central flat region 154.

Now see also Figure 22, it is the top view that shows these wooden platform 148 global shapes, also comprises the top view shape that this plays tail 150; Make the plank or the glued board of this platform 148, its vertical ridge orientation is preferably with shown in the direction of arrow 158, and lines can make wooden platform 148 have preferable anti-infringement characteristic longitudinally, for example can prevent to cause fracture because of twisting when these slide plate 146 operations; Most layers in a glued board use this vertical lines technology, and for example top layer and the bottom in three layers of glued board uses, and be especially more helpful.

Now see also Figure 23, this figure plays the stereogram of tail 150 for this slide plate 146 together with this.

Now see also Figure 24, it is the top view that shows another preferred embodiment of the utility model, slide plate 160 is to include a pair of central chock 162,164 are placed in a pair of perforation 161 of platform 166, so that control the flexibility (flexure) of this platform 166, these perforation 161 are to be positioned on the major axis of this platform 166 haply, and the central point in this slide plate 160 is split two halves, can select filling chock 162 in these perforation 161,164 or not filling chock 162,164, so that control the flexibility (flexibility) of this platform 166, if these chocks 162, the flexibility of 164 materials is better than the flexibility of these platform 166 materials, better when the flexibility of this platform 166 can be removed than these chocks 162,164, but can than do not establish these whens perforation poor.

Similarly, if these chocks 162, when the flexibility of 164 materials differs from than this platform 166, these chocks 162,164 existence will reduce for the flexibility that puts on the torque forces on the slide plate 160, for example can reduce for the flexibility that is applied by the user with the application of force so that slide plate 160 advances, these chocks 162,164 flexibility also can be used to control or influence the running of this slide plate 160, for instance, if when the material of these chocks 162,164 is the material (for example foam) that can temporarily be pushed when bearing external force, slide plate 160 will not established these chocks 162 to differ from, the bending of 164 o'clock form, especially, the speed that applies when torque forces, be lower than this slide plate 160 because of torque forces remove reinstatement the time speed the time, this slide plate 160 still can bend distortion, and this is because the extruding of the foam resistance can form torsional deformation the time causes, yet, because foam rests on squeezed state blink to I haven't seen you for ages, so the resistance the when extruding of foam can't form these slide plate 160 reinstatements.

In addition, this chock 162, if 164 made by elastic rubber (springy rubber), the torsional deformation of this slide plate 160 will be influenced by the reaction of this rubber, it is faster when for example the answer speed of this slide plate 160 can more not established these chocks, even under some situation, only use a chock to have more gratifying result on the contrary, for instance, if only establish chock 162 and do not establish chock 164, the elasticity of these slide plate 160 front sides can be controlled so as to the elasticity that differs from these slide plate 160 rear ends, that is, this slide plate 160 drags the elasticity of the torque forces that adds for user's forward foot in a step, is to drag the elasticity of the torque forces that adds for user's rear foot according to this slide plate 160, and is adjusted at least a little; The wheel spare (not shown) that is positioned at this below, platform 166 front and back district can make and put on the external force of distinguishing before and after this slide plate, is isolated from each other to being less than to a certain degree, and influenced by the material of this chock 162,164; In present embodiment, this chock 162,164 is to use different materials, so that make the relative resilient in these slide plate 160 forward and backward districts obtain more accurate control.

The chock 162,164 of rounded and the somewhat similar bone shaped of shape, and penetrate these platform 166 usefulness for the perforation 161 that chock is provided with, can reduce this slide plate because of the crooked possibility that ruptures and produce defective.

Now see also Figure 25, single chock 166 is to place in the single perforation 167 of this platform, and is positioned at same position with a pair of chock of Figure 24, and this perforation 167 can also not established the mode of this chock 168 and be used.

Now see also Figure 26 to Figure 29, slide plate 170 shown in another preferred embodiment of the utility model is to comprise a platform 172, this platform 172 is before this, rear portion 174,176 partial lateral is to be provided with most embeddings wellblock 180,182,184,186, these embedding wellblocks 180,182,184, in 186 and be provided with tread plate 188,190,192,194 (grip bar), that is by the made chock 188 of rubber, 190,192,194, each chock 188,190,192,194th, it is contour with the end face of this platform haply to include non slip surface on (gripping surface), and can contact with user's biped, to provide user's foot better antiskid function, this embedding wellblock 180,182,184,186 can comprise one be positioned at inboard towards lower wall 212, one trough floor 214 and one be positioned at the outside towards upper wall 216, this trough floor 214 be located at this towards lower wall 212 and this towards between the upper wall 216, this is in order to increasing the bend resistance resistance of sufficient Support towards upper wall 212 and towards lower wall 216, it is a pair of that what be positioned at these platform 172 mesozones 208 is in order to reduce the bending degree of this mesozone towards lower wall 212, and be can further control this mesozone to by the bending degree that torque forces caused between this towards the chock between the lower wall, for example control the bending degree of this district to the torque forces that the user applied.

Now please pay special attention to Figure 26, this platform 172 is before including formation, one anterior 174 and one rear portion 176 of metapedes Support, the middle body 178 at this front portion 174 and this rear portion 176 respectively has a special texture surface (textured surface) 178, it can form when this platform 172 is moulded easily in the lump, 172 suggestions of this platform can plastics or timber (similarly being glued board) mould and form, what make sometimes also can not have as the so strong anti-skidding power of non skid matting, these embedding wellblocks 180,182 can form along these front portion 174 peripheries, and 184,186 in these embedding wells can form along these rear portion 176 peripheries, in these embedding wellblocks 180,182,184, but the suitable material of 186 fillings, rubber for example, so that a preferable non skid matting that contacts with user's foot or heel is provided, this material is can be as chock 188,190,192,194 is general, is available for users to distinctly freely replace, and this chock is can rubber, plastics, metal alloy or its analog replace.
