Some is similar to the structure of front wheel truck 24 for rear truck 25, comprise L shaped back mounting bracket 88, back mounting bracket 88 have the level board 89 that is suitable for being fixed on heel slab 29 bottom surfaces and with level board 89 monolithic moldings and the sagging plate 90 of the protruding spherical 92 of qualification (Fig. 8 and 10) on the face 91 within it.A pair of hold-down arm 94 extends from the both sides of level board 89, and by pivot mechanical screw 96 and lug 95 pivotal engagement outstanding from heel slab 29 bottom surfaces.Level board 89 further is fixed on heel slab 29 bottom surfaces by a pair of mount pin 98, mount pin 98 1 ends are connected with the level board 89 of mounting bracket 88 by mechanical screw 99, the other end has the eyelet 100 that extends through perpendicular elongate groove 101, groove 101 is limited in the rib 102 of the isolated corresponding bowed shape on heel slab 29 bottom surfaces, and groove 101 passes the upper surface open of heel slab 29.Eyelet 100 receives mount pin 104, and mount pin 104 is fixed in the eyelet by extending through eyelet 100 upper limbs and can entering the hold-down screw 105 that passes the opening of groove 101 in the heel slab 29.Rib 102 is installed is defined convex bending outer surface 107, and the level board 89 of L shaped after-poppet 88 defines and is applicable to the corresponding bow surface 108 that receives arc elastic damping pad or liner 109 that damping is provided, thus as above-mentioned to providing vertical buffering for the wheel that is installed on the ice skate plate the discussion of front wheel truck.

Axle yoke 110 is provided for pair of rear wheels 21 is installed on mounting bracket 88, thereby does swing or banking motion around a tilt axis to described above similar.Axle yoke 110 by central web 111 with constitute from its extended relative side arm 112.Side arm 112 comprises the hole 114 that lining 115 is housed, and pivot pin 116 extends through lining 115 and fixing by mechanical screw 118.The wheel 21 that can have internal bearings 119 is installed and is supported on the pivot pin 116.Yoke 110 is installed on the vertical panel 90 of back mounting bracket 88 pivotally.For this reason, yoke web 111 define corresponding to and receive the concave ball shape supporting surface 120 of vertical installing plate 90 epirelief spherical surfaces 92.Trunnion 121 extend through in the supporting plate 90 and yoke web 111 in each self-corresponding hole 122,123.Hole 122,123 and trunnion 121 acutangulate downwards and the axis 124 that turns forward is arranged along the horizontal plane of relative heel slab 29.Pivotal line 124 that tilts and spherical 92,120 make that wheel can tilt and turn to as skater during to a side or opposite side inclination.This banking motion, is put in this pad with the integrally formed protuberance 128 of the web of trailing wheel yoke 110 in pad 125 grooves 126 that are installed in the support level plate 89 by 125 restrictions of resilient U-shaped damping pad and control.By changing the consistency and elasticity of elastic damping pad 125, the swing that can control yoke and pair of rear wheels 21 is to be fit to the skater.Installing plate and wheel yoke are positioned at heel slab position a little backward with this to trailing wheel, so just as shown in Figure 4 in the calcaneal back of skater.This structure has not only been strengthened skater's balance but also make its easier use rear brake 40.

As mentioned above, all be spherical at the field of conjugate action between the vertical panel of wheel yoke and mounting bracket on front wheel truck and the rear truck.The field of conjugate action of taking turns yoke when each is a spill, and the corresponding field of conjugate action of each mounting bracket plate is exactly a convex.This structure is similar with ball-and-socket joint to ball, and the rotation that makes the wheel yoke limit around mount pin with respect to mounting bracket pivots or rotation.The rotation 78 of a pair of front-wheel and the rotation of pair of rear wheels 124 makes as skater during to a side or opposite side inclination, the two pairs of wheels tilt or turn to, thereby slide to curve or camber line steering-effecting is provided, wherein

rotation

78 and 124 is that the plane of longitudinally and relatively toe board and heel slab becomes downward acute angle.For example, if the skater is in order to turn left and to be tilted to the left along a camber line, when this pivoted to the right to trailing wheel, this pivoted left to front-wheel so, thereby turning to left is provided.Equally, when the skater is tilted to the right in order to bend to right, also can obtain identical turning efficiency.In both cases, the 3rd wheel on the front wheel truck do not rotate, and so just during the turning of either direction, and during the skater uses side wheel to promote with the raising sliding speed, provides stability.

Wheel 21 is preferably the wheel form of typical case's use in single ice skate, and they are made by wear-resisting polyurethane or other plastic material that is fit to durable and long service life.Single skating shoe wheel is preferred, is because comprise or when the rotation of wheel shown in Fig. 7 intercepts the common ovalize of this cross section when the cross section of wheel.Ellipse is preferred, because it has circular wheel face, this makes the easier realization of skater turn.Traditional four-wheel roller skates generally has flat wheel face, makes the difficult realization of skater turn, and this is because the skater who uses flat wheels not as the skater who uses the wheel that how round wheel face is arranged, can tilt so much to the direction of turning.

Front brake 39 is made up of the brake pad 129 that is installed on the brake holder 130 that is fixed in the toe board bottom surface.Rear brake 40 comprises the brake pad 131 that is fixed on the upright heel flange 32 that is installed on the heel slab back equally.Flange 32 is further used as the heel block that engages the skater's footwear heel.

Telescopic extension mechanism 30 makes toe board 28 and heel slab 29 vertically to regulate relative to each other, its elongate strip 135 and a pair of elongated slot 136 by the cross section across constitutes, wherein, elongate strip 135 is fixed on heel slab 29 bottom surfaces and extends to toe board 28, and elongated slot 136 two grooves as shown in Figure 5 is fixed on the toe board with facing with each other.Bar 135 defines the side direction projecting rib 137 in the groove 136 that engages to advance to be fixed in toe board, thereby telescopic adjustment is provided.Definite when the length adjustment of toe board and heel slab, bar and groove are just fixing by being used at the mechanical screw 96 of heel slab bottom surface installation bogie.This screw can be tightened or unclamp with engaging groove and bar, thereby ice skate are fixed on required length.In addition, this skate structure is preferably made by light plastics or metal, as aluminium.

The skater is placed on the ice skate by the weight with health, advances with the nearside wheel of another footwear simultaneously to promote on ice skate oneself.Because skating shoe wheel is to pivot to install, when the skater used ice skate to advance, wheel turned to easily.The 3rd wheel of this propelling ice skate front provides stability, and makes the skater can obtain strong propelling or promotion.The 3rd wheel on the front wheel truck also when sliding forward or backward, and on irregular surface for example pavement, path and when on branch and stone, sliding, provide stability to the skater.

Figure 11 and 12 illustrates four-wheel roller skates 220 of the present invention, and it is different from the ice skate 20 of first embodiment, because it only is provided with a trailing wheel 221 that replaces pair of rear wheels 21 described in Fig. 3.The most clearly demonstrate among Figure 11, trailing wheel 221 is provided with in line with single centre wheel 22, and they all rotate in same plane like this.If run into ground thrust, pad 109 can compress, therefore wheel 221 will move up, so in order to prevent that trailing wheel 221 from contacting with the support 232 of rear brake 40, the shape of support 232 also designs to such an extent that be different from the support 132 of the brake 40 of first embodiment.The trailing bogie 225 of this embodiment is also different with the bogie 25 of first embodiment, because it only need be used to install a wheel, promptly takes turns 221 structure (mark), rather than is installed in a pair of on the trailing bogie 25 and takes turns 21.Other parts of ice skate 220 are identical with ice skate 20, so its mark is identical.

The stability that ice skate 220 provide is provided not as ice skate 20, but because it has only utilized a trailing wheel, so it is more flexible and lighter.

The present invention also is applicable to three-wheel ice skate (not shown), and it will be similar to ice skate 220, but does not utilize centre wheel 22, is about to centre wheel 22 and removes from ice skate.This ice skate will be stablized not as

ice skate

20 or 220, but it is in light weight and very flexible.This ice skate can not resemble to use and make the skater produce so big thrust the ice skate 20,220, and this is to be believed to the very big thrust of generation in description embodiment because promote the ability of the three-wheel combination of two front-wheels 21 and single centre wheel 22.

Although being described as, the present invention has preferred design, but be appreciated that it can do further to revise, uses and/or improve on the basis of following the principle of the invention substantially, and it comprises such as the known or routine test that utilizes in the technical field of the invention, and such as may be use above set forth and fall into the scope of the invention and the claims principal character in limiting to change of the present disclosure.
