Description

Roller-skate with falling-down-prevention function

The utility model relates to daily living article, the roller sport footwear of particularly amusement, body-building.

Existing roller skate, as the patent No. is that 86209428 " roller skate that has ratchet structure " and the patent No. are " sliding the footwear of travelling " of 91217635.0, though increased ratchet and pawl arrangement, roller skate can only be rolled forward, be convenient to the beginner and grasp, few wrestling.But the people is in case when the hypsokinesis, have nature to retreat the conditioned reflex in several steps, and in the hope of balance, pin is pedaled forward, has quickened the rolling forward of wheel, and it is bigger that the people understands hypsokinesis, falls down backward at last.So these two kinds of roller skates can not prevent that the people from falling down backward.And ratchet and pawl arrangement also has bigger noise, only is suitable for slowly running.The patent No. is 92206049.5 " orientation slides sole ", being equipped with fixing zigzag rubber boots at rear heel follows, number of patent application is 92218250.7 " roller skate that can brake ", at the pedal end braking pillar is arranged, they are except that braking, can play necessarily retreat anti-and fall effect, but they can not prevent that the people from dumping forward: center of gravity leans forward, the people has the conditioned reflex in several steps of leaping up naturally forward, in the hope of balance, pin is pedaled backward, and wheel rolls immediately backward, it is more that center of gravity is leaned forward, and falls down forward at last." orientation slides sole " also must stand on tiptoe with tiptoe and slide, and the shortcoming that makes pin fatigue is arranged.

The purpose of this utility model is the deficiency at above technology, and a kind of comprehensive anti-roller skate that falls is provided, and makes the beginner be difficult for wrestling, learns easily, and can be used as the walking-replacing tool of short distance.

The purpose of this utility model takes following measure to realize.The anti-roller skate that falls mainly comprises base plate, connecting plate, the two pairs of wheels and axle and bracing strut thereof, heel, heel and back heel before it is characterized in that being provided with, before and after footwear, see that heel is flute profile (notch can be with the right angle crimp), the groove waist is cut tongue (" door " notched cut is pressed in the groove), be equipped with rubber bumper and pad below the bottom land, change the gross thickness of rubber bumper and pad, the height of adjustable heel; Base plate is divided into four: preceding with plate, preceding wheel plate, back wheel plate, heel plate, they all have a hole, be movably connected on four stay bolt holes of connecting plate with bolt respectively, forward and backward with the fixedly connected forward and backward heel of difference under the plate, forward and backward wheel plate is the fixedly connected forward and backward bracing strut of difference down, move forward and backward wheel plate, the position of adjustable front and rear wheel; Make bearing with roller-type overrunning clutch, can only one-directional rotation; Connecting plate is formed by connecting with hinge by two sections channel-section steels that Open Side Down, because withstand mutually two channel-section steel both sides, hinge can only up rotate, and forward and backward heel is pierced at the connecting plate two ends.

The utility model compared with the prior art, its advantage is to prevent wrestling, easily association has learned and can also use.Because forward and backward all have a heel, there is rubber the bottom surface, and height heels is adjustable, and the position of wheel is also adjustable, just has anti-comprehensively performance of falling.Make bearing with roller-type overrunning clutch, the wheel single roll is convenient to the beginner and is grasped, and can also pedal straight ahead backward; It is compared with ratchet and pawl arrangement is compact conformation, and noiseless is suitable for high speed rotating.Connecting plate has hinge, make the people carry pin, after when pedaling, shoestring is the plinth back of the body not; Hinge can only up rotate, make the people step down in anti-when falling on the roller skate four base plates be flat.The anti-roller skate that falls can also be as the walking-replacing tool of going to school, going to work.

Below provide accompanying drawing, further specify in conjunction with the embodiments.

Connecting plate 7 is formed by connecting by hinge axis 19 by channel-section steel 17,18.Two stay bolt holes at two ends, the connecting plate back side, be before connecting with plate 1, heel plate 13, regulate and anti-ly fall that roller skate length uses, these two stay bolt holes also can change two string holes into; Two stay bolt holes in the middle of the connecting plate are wheel plate 6 before the connection, back wheel plate 8, bracing strut 5, bracket of back axle 9 before connecting again, and adjusting front and rear wheel position is used.Preceding heel 2, back heel 12 are followed plate 1, heel plate 13 times before being fixedly connected on respectively.Star-wheel 14 is fixed together motionless with front axle 4, rear axle 10.When outer hub 15 clockwise rotated, roller 16 played roller in the bearing; When outer hub rotated counterclockwise, because the frictional force between outer hub and the roller also rotates counterclockwise roller, consequently roller outside between hub and the star-wheel, was stopped operating outer hub by wedge.This has just realized the one-directional rotation of outer hub.If all wheels are all made bearing with roller-type overrunning clutch, anti-falling property is fine, be fit to a middle-aged person and use, but the cost height; If be that a pair of front-wheel uses, the suitable walking-replacing tool of doing; If all use plain bearing, cost is low, is fit to the teenager and uses.Front-wheel 3, trailing wheel 11 can also be rubber wheel, carbamate wheel, nylon wheel etc. except that being the iron tyre.For the beginner, transfer heel not wipe mutually with ground near ground, transfer wheel near the footwear middle part but step on surely.If people (back) forward topples over, people's weight is concentrated on the ball of foot (heel) and since preceding (back) heel liftoff nearer, take turns far from preceding (back), preceding (back) heel just lands easily, at this moment back (preceding) wheel is liftoff, and the anti-roller skate that falls becomes to front slide by rolling forward; If people (back) forward topples over too greatly, the people has forward (back) the leap up conditioned reflex in (moving back) several steps, and in the hope of balance, pin (preceding) is backward pedaled, and at this moment roller skate becomes backward (preceding) by rolling forward and slides.Because preceding (back) wheel is far away from preceding (back) heel, power before ball of foot (heel) is stepped on (back) heel is just bigger, add that the rubber coefficient of friction at the bottom of the heel is big, the frictional force on preceding (back) heel and ground is just big, therefore, compare with rolling forward, the speed of slip reduces greatly, people's balance that is able to do in time is unlikely and falls down.Recover normal then at once, move on.The front-wheel single roll also can prevent to dump forward, but then will leap up forward several steps as unmatched heel.The beginner generally can not fall down as not doing high-leveled and difficult actions such as zig zag, rotation, even fall down once in a while, because heel and ground friction are arranged, speed is little, and the people falls down to the ground slowly, also just falls gently.We cross experiment with the crop rotation of plain bearing, and the beginner does not fall down, and tentatively can slip in one hour.Progressively association progressively transfers height heels, back wheel location.For the people who has learned, transfer trailing wheel to hold to the end, transfer heel overhead the highest, prevent that falling roller skate just becomes common roller skate, heel can be done brake and use.
