Abstract

The utility model relates to a pair of anti-fall land roller skates, which is mainly composed of a front footplate, a back footplate, a front wheel, a back wheel, small rollers arranged on the lower side of the front footplate for preventing fall forwards, and a supporting seat arranged on the rear part of the back footplate for preventing fall backward. The small rollers can touch ground when skaters have the tendency of falling forwards; the lower part of the supporting seat can touch ground when the skaters have the tendency of falling backward. A supporting point can be added instantly before the skaters fall down, and the supporting point can control the speed of the roller skates. The skaters can adjust the barycenter independently by personal inertia. The utility model can play the role of preventing falling.

Description

Anti-fall land skating boots

The utility model relates to a kind of roller skate of falling down can prevent roller skating the time.

Present double totally four roller roller skates that generally use do not possess and prevent the device fallen down, the beginner and not too the practician fall down through regular meeting.There is some roller skate conical block rubber or unit of plastic to be housed, just is used for figure skating, rather than prevent that the skater from falling forward at its front end; And notification number is 92218250.7 for the CN2124737U(application number) disclosed " roller skate that can brake ", because its " hind axle basically when the single pin of user is stood naturally on the equilbrium position of center of gravity ", its hind axle is far away from the more common skating boots of skating boots heel like this, and human body its center of gravity when roller skating always is partial to the rear unconsciously, therefore " roller skate that can brake " drops on the trend that its hind axle has layback to fall down afterwards than the easier skater's of the making center of gravity of common skating boots, but owing under its pedal end portion a braking pillar is arranged, can brake skating boots, so just make the skater who wears " roller skate that can brake " between " to advancing slip; move after the center of gravity; braking ", circulate unconsciously, and the possibility that also has backward bending throw to fall and before fall.Therefore existing roller skate comprises the problem of falling down when disclosed patent all fails to solve roller-skating well.

Aim of the present utility model is exactly that a kind of roller skate of falling down can effectively prevent to skate the time will be provided, and to reduce and to avoid skater's damage, improves the interest of skating; Also be for wearing the workman of roller skate work simultaneously,, provide the walking-replacing tool of safety as the textile worker.

The utility model is realized with the following method: it is mainly by front running board, bumper step, front-wheel, trailing wheel and be equipped with below front running board and prevent the trundle that dumps forward and be equipped with at the roller skate rear portion that the supporting seat fallen down of preventing to swing back constitutes.Axle is equipped with at the trundle center, the axle two ends are contained on the fore-stock, fore-stock curves with steel plate, between its top and the skating boots front running board yielding rubber is housed, and with bolt location, trundle is before the skating boots front-wheel, when the skating boots four-wheel all lands, the trundle lower end is plane 5-15mm above Ground, and trundle can be bakelite, plastics, nylon or metal.And anti-ura-rate supporting seat is made up of tilted supporter, clamping plate, rim, tilted supporter can be fixed on skating boots bumper step rear portion and afterwards on the wheeling support, and tilted supporter can curve with steel plate, its cross section be "

" shape; tilted supporter recedes; this makes anti-ura-rate supporting seat integral body recede; the rim that clamp by clamping plate the tilted supporter lower end is screwed between tilted supporter and clamping plate and the rim, when the skating boots four-wheel all lands; the rim lower end is 2-8mm overhead after the bumper step rear end of skating boots; rim is to make with material wear-resisting and that have better elasticity and a coefficient of friction, and as the rubber of plastics, nylon and ratch tire, rim can be changed after wearing and tearing.Can pull down fore-stock and trundle by the set bolt that unclamps between front running board and the fore-stock, the hold-down screw and the bolt of come loose anti-ura-rate supporting seat and bumper step and back wheeling support can be pulled down anti-ura-rate supporting seat; Simultaneously, also can below the front running board of ready-made roller skate, use bolting fore-stock and trundle, can be with screw and bolt preventing that the ura-rate supporting seat be fixed on the back lower place of bumper step and back wheeling support, makes roller skate possess the shatter-resistant function.

Use the skater of shatter-resistant roller skate, when the trend of falling forward, skating boots heel one is mentioned, trundle will land, this just make skater this moment many a strong point, trundle also rolls forward together together with the skating boots front-wheel simultaneously, and this just can make the skater be unlikely forward under the support of ground in the face of the active force of trundle generation and fall down; When skater's center of gravity after trailing wheel and when having layback to fall down trend, forefoot one is upwards carried, the skating boots front-wheel is with regard to built on stilts, rim just contacts with ground like this, the skater is played a supportive role, again because the friction on rim and ground, the speed of skating boots is slowed down, and skater's upper body part is because inertia, and speed will be faster than footwear, and this just makes skater's center of gravity can get back between the front and back wheel of skating boots, so the skating boots front-wheel lands, the rim built on stilts, the skater can continue again to slip forward safely, plays the effect of shatter-resistant.It is particularly suitable for the beginner and learns roller skating.

Accompanying drawing is an embodiment of the present utility model.
