Abstract

The utility model relates to a pair of roller skates with large wheel diameters, short shoe bodies, and light weight. The landing places of wheels can be arranged under pedals. Each roller skate is composed of wheels, a rolling device, a support frame, a pedal, and an auxiliary wheel, wherein, the wheels can be hollow and is slightly inclined with the ground; the auxiliary wheel performs functions of an assisted pedal and a brake. The utility model can rapidly run on the general road surfaces like bicycles. Because the utility model can be carried for taking a public vehicle, people can adopt a popular, economical, and effective transportation mode which combines ' the roller skates of a close distance ' and ' a vehicle of a long distance '. The inconvenience of time consumption and labor consumption by oneself and walk for changing the public vehicle can be avoided.

Description

Roller skates

The utility model belongs to a kind of roller skate.

The roller skate that has been widely used is single or double the wheel, the roller skate of wheel under pedal.It takes turns the place that requires to have smooth planar when slide for a short time in the footpath.People expect that always roller skate can be as bicycle, can be on general road fast running, handle flexibly and brake, allow people enjoy portable individual traffic means of transport.For this reason, emerged in large numbers the novel skates structure design of many kinds.Because exist wheel footpath hour, slide effort, speed is slow; Wheel footpath hour, the footwear body is long, reach heavily that the wheel touchdown point can not drop under the pedal and not steerable contradiction still can not make people's expectation become a reality.

The purpose of this utility model is to provide a kind of and takes turns that the footpath is big, the footwear body is short, weight is little, the roller skate that the wheel touchdown point can be under pedal.It can slide on general road fast, handles flexibly, brakes, and takes amusement walking-replacing tool generation, that enable at any time, safety with oneself as people.Make people be adopted " in-plant roller skate " mode of transportation of combining such as " long-range automobile " together.

The utility model is to realize by the roller skate that following design provides.This roller skate is made up of wheel, tourelle, support, pedal and auxiliary wheel etc., and it is characterized in that: wheel and support mutually combine by tourelle and fix, and wheel can freely rotate, and wheel can be a hollow-core construction; Pedal is fixed on the support, be in the wheel subcenter with upper/lower positions, the angle between pedal and the wheel plane can be adjusted, wheel can furnishing tilts, and the wheel touchdown point is positioned under the pedal, adjusts rear pedal and retightens with support; The top of support is provided with ties up fixing apparatus, and shank is fixed, and allows it to move forward and backward, and guarantees that pin can be normal crooked, does not allow it to swing, and is easy to stand firm after people are worn; Auxiliary wheel is positioned at the rear lower of wheel, connect with support, this connection can have certain flexible compression elongation range on vertical, when the gravity center of human body moves forward, elastic force has lifted up the pedal rear portion greater than gravity, plays the effect that the angle is pedaled in boosting and reduced side, when tiptoe has upwards been lifted up, move behind the gravity center of human body, be compressed, and with support forward then auxiliary wheel wheel, the two-wheeled friction that furthers is produced braking.

Accompanying drawing is the utility model structural representation, also is one of embodiment.Fig. 1 is a front view, and Fig. 2 is a right view, and Fig. 3 is a vertical view.

1, pneumatic tire 2, wheel inner edge track 3, scroll wheel

4, pedal 5, tie up fixing apparatus 6, auxiliary wheel

7, waling stripe 8, vertical elastic link 9, support

Adopt this embodiment can reach that wheel footpath is big, the footwear body is short, in light weight and touchdown point is positioned at optimum efficiency under the pedal.

Below in conjunction with the embodiment accompanying drawing the utility model is described further.

Wheel is hollow wheel rim, its outer rim is a pneumatic tire 1, inner edge is the triangular form track 2 of projection, scroll wheel 3 its outer rims are recessed triangular form shape, just in time coincide with the wheel inner edge, scroll wheel is fixing with support 9 by wheel shaft, bearing, as shown in Figure 1,6 scroll wheels are fixed on the wheel subcenter as tourelle with support, and wheel can freely rotate along support.From Fig. 2 as seen, pedal 4 is fixed on the support, is in the side on the lower side of wheel subcenter, and pedal is a level, and the wheel in the vertical direction is a slight inclination, and the angle of inclination can be adjusted, and can the two be fixed after the adjustment.Drop under the pedal from the visible wheel touchdown point of Fig. 3, as skates.Fixing apparatus 6 is tied up in the cantilever tip setting, and shank is pinioned, and pinioning gaskin should be able to move forward and backward, but no longer can swing, and is easy to keep in standing and sliding health more stable.Auxiliary wheel 6 connects with support by waling stripe 7 and vertical elastic link 8, the two ends of two bars are all rotatable, and vertically bar can extend and be compressed within the specific limits, when the gravity center of human body moves forward, vertically bar extends under the elastic force effect, the pedal rear portion has been lifted up, play the effect of pedaling that helps, also dwindled the angle of pedaling laterally simultaneously, play the labour-saving effect, lift up the time-out gravity center of human body when tiptoe and move backward, with the auxiliary wheel wheel that furthers, both rub and produce braking.Because human weight mainly dropped on the touchdown point of wheel, auxiliary wheel is only born a small part weight, and the distance between two wheel touchdown points is very short, so people are easy to steering under steam.Can wheel cover be set in the wheel outside, fix, avoid tire that clothing is made dirty with support.

The utility model has the advantages that: it is big that 1, this roller skate has the wheel footpath, and pneumatic tire is housed, and brake gear is reliable, is easy to the performance of steering, can be as bicycle at general road surface going. 2, because this device has been liberated both hands, can stop and stand, and tie up fixing apparatus and can stand more surely, more easily look after all directions, so safer as the vehicles. 3, the distance of growing distance is carried roller skate and is taken automotive, short distance before and after this adopts roller skate to ride instead of walk, no matter the mode of transportation of this two combination is at auto age, the bicycle epoch all are flexible, popular, more economical effective mode of transportation. 4, compare with bicycle, the mode of transportation of this two combination has increased people's radius of action, has improved the traffic speed per hour, has broken through the restriction of bicycle speed per hour to the urban development scale, has reduced bicycle and has taken up an area road occupying. 5, compare with automobile, closely the interior roller skate that adopts has avoided automobile to deposit the puzzlement of road occupying and traffic jam, Alleviate traffic pressure, saved the energy, reduced air pollution and noise pollution. 6, provide a kind of more extensive, body-building recreation utensil more at any time, overcome skating is enjoyed in season and ice stadium to people restriction. 7, simple in structure, the investment little, cheap, be convenient for people to travelling, tourism, amusement.
