Abstract

The utility model relates to exercising boots used on land, particularly a high-speed roller skating boots. The shapes of the high-speed roller skating boots are similar to the shapes of the existing single-row roller skating boots. Each of the high-speed roller skating boot comprises a boot body, a boot holder, and a group of wheels which are specially designed, wherein, the left and the right outer round surfaces of the wheels which are symmetrical by a central line which makes contact with the ground and is used as a symmetry axis have two horizontal included angles within 0-25 DEG with the parallel line of the axis; the peripheries of the wheels form double brackets, so that the ground touching area is increased, and the running can be stable and safe. When a person accelerates at corners and on straight roads, the inner and the outer wheels of each boot can cut the skating surface along the knife line which is converted into an acute angle, so that the friction surface can be reduced without forming side shift, the speed can be increased with less labor, and perfect skating postures can be guaranteed.

Description

High speed roller skates

The utility model relates to a kind of footwear, particularly a kind of single roller skate.

Existing single roller skate generally is made up of footwear body, shoe rack, wheel three parts.Wheel is connected with shoe rack by wheel shaft and bearing, on the right footwear shoe rack brake shoes is housed, shoe rack is installed on the footwear body, every footwear body is equipped with 3～4 wheels arranged in a straight line in single file, wheel cylindrical tread surface is that semicircular arc is domatic, singlely take turns that to land be a point, stand, each point contacts to earth in alignment when sliding.Therefore, the user stands, slides easily and topple over to the left and right, keeps balance and feels painstakingly, very easily sprains ankle, tumble injury health; In sliding curve, straight line quicken, be easy to generate the side displacement, consume firmly, quicken not exclusively to be difficult to obtain higher ski-running speed.

The purpose of this utility model provides a kind of high speed roller skates that can overcome above-mentioned shortcoming.

The utility model comprises the footwear body, shoe rack, wheel, wherein wheel is connected with shoe rack by wheel shaft and bearing, on the right footwear shoe rack brake shoes is housed, shoe rack closely is connected on the footwear body, every footwear body is equipped with 3～4 wheels arranged in a straight line in single file, it is characterized in that: the center line with the wheel tread surface is two horizontal sextant angle α of symmetrical axisymmetric left and right sides periphery and axle parallel lines, β is 0～25 degree, its top of taking turns the skeleton brace rod also should be symmetrical mutually, two horizontal sextant angle α ' with the axis parallel lines, β ' also is 0～25 degree, and the tire layer of wheel skeleton brace rod and wheel tread surface is annotated and is integrated.When horizontal sextant angle α, β all spent greater than 0, tread surface had cushioning effect to ditch, bank, foreign material.The diameter of wheel is that 5～8cm, thickness are 2～3cm.

The utility model has the advantages that: the outer of a plurality of wheels forms double bracket before and after utilizing, and stands and has increased the area that contacts to earth when sliding, and advances steadily, is difficult for spraining ankle, tumble injury health; When bend and straight line quickened, because the basic principle of ski-running, interior foreign steamer had not only reduced rubbing surface but also has not formed sidesway along the acutangulate cutter line cutting of conversion planing surface, thereby made speed increasing force saving and guarantee the perfection of gliding position.

Below in conjunction with accompanying drawing, embodiment of the present utility model is described:

Accompanying drawing 1 is the utility model embodiment profile schematic diagram

Accompanying drawing 2 is the profile schematic diagram of the utility model embodiment wheel

Accompanying drawing 3 is the generalized section of 0 degree for the utility model embodiment wheel α, β

Accompanying drawing 4 is the generalized section of 25 degree for the utility model embodiment wheel α, β

Embodiment of the present utility model is made of high side cushion footwear body 1, plastics shoe rack 2, rubber and plastic wheel 3, wherein wheel is connected with shoe rack by wheel shaft and bearing, on the right footwear shoe rack plastics brake shoes 4 is housed, shoe rack closely is connected on the footwear body, and every footwear body is equipped with 4 wheels arranged in a straight line in single file (accompanying drawing 1).Wheel is made of plastic skeleton 5, rubber tyre 6, and plastic skeleton comprises that the rubber wheel plies of brace rod and wheel tread surface annotates be integrated (accompanying drawing 2); The diameter of wheel is that 6cm, thickness are that the diameter of bore of 2cm, wheel is 1.4cm, outer bore dia is 2.4cm, plastic skeleton does not comprise that the diameter of brace rod is 3.5cm, the cladding thickness of rubber wheel plies on the plastic skeleton brace rod is 0.3cm, and returns bag brace rod (referring to accompanying drawing 3, accompanying drawing 4) fully; The center line that accompanying drawing 3 has been expressed with the wheel tread surface is two horizontal sextant angle α of symmetrical axisymmetric left and right sides periphery and axle parallel lines, β is 0 degree, it takes turns the top of skeleton brace rod and two horizontal sextant angle α ' of axis parallel lines, β ' also is 0 wheel subcharacter when spending, the center line that accompanying drawing 4 has then been expressed with the wheel tread surface is two horizontal sextant angle α of symmetrical axisymmetric left and right sides periphery and axle parallel lines, β is 25 degree, it takes turns the top of skeleton brace rod and two horizontal sextant angle α ' of axis parallel lines, β ' also is 25 wheel subcharacters when spending, select the number of wheel, adjust α, β, α ', the value of β ', can obtain different technical characteristics, can adapt to different user's requests, usually α=α '=β=β '.

Claims
