Abstract

The utility model relates to a pair of roller skates with brakes. Each of the roller skates is mainly composed of a foot board, a front wheel shaft, a rear wheel shaft, four wheels and a braking post arranged on the tail end of the foot board. People who wear the roller skates with brakes can slide forward, or can reduce speed, or can stop at will, the utility model is convenient in use, people are not easy to fall, and the utility model can be used as a safe tool for riding instead of walk.

Description

Skates with brake

The present invention is a kind of roller skate of braking.

Existing roller skate mainly is made up of pedal, front axle, hind axle and four wheels, also have plenty of pedal is divided into forefoot pedal and rear heel pedal, connect by beam, distance between the two can be regulated, with the size of the pin that adapts to different people.What have can also be by there being damping device between front axle, hind axle and pedal, and still existing roller skate does not all have brake apparatus, user, especially begin to learn the user, be difficult for grasping, very easily fall down, we can say, learn to use roller skate, do not fall down repeatedly.With roller skate as a kind of walking-replacing tool, many times than walking speed is fast, and save muscle power, in some workplace, as the textile worker, if can put on roller skate as walking-replacing tool, both can save physical demands, more can increase work efficiency, but existing roller skate does not have brake apparatus, dangerous, be prone to accidents.

The object of the present invention is to provide a kind of roller skate that can brake, be not easy during use to fall down, can be as the walking-replacing tool of a safety.

The roller skate of braking of the present invention is mainly by pedal, front axle, hind axle, four wheels and form at a braking pillar of pedal end.The position of hind axle is basically when the single pin of user is uprightly stood naturally on the subpoint equilbrium position of center of gravity.Pillar square tube that this braking pillar can be made by a steel plate and the pillar square made from the bigger elastomeric material of coefficient of friction constitute with bolting, and the pillar square tube also can be replaced by the steel plate of two crimpings.When the four wheels of roller skate all lands, the following end distance ground level 4～14mm of pillar square.The material of pillar square can be a vulcanite, and the roller skate of braking of the present invention can be made the position of hind axle on front and rear direction and can regulate, so that it is adjusted on the equilbrium position when being fit to the different users and using.The braking pillar can be made self-mountable ﹠ dismountuble, when not needing to brake pillar, can remove the braking pillar, will move behind the hind axle simultaneously, promptly becomes existing roller skate.

The roller skate of braking of the present invention can be as existing roller skate, pedal is divided into forefoot pedal and rear heel pedal, connect by beam, the distance between forefoot pedal and the rear heel pedal can be regulated, use with the user who is fit to different statures.In addition, also can be between forward and backward wheel shaft and the pedal by the dress damping device.

The user use of the present invention when braking roller skate, as long as centre of body weight moves slightly backward, the front-wheel that makes roller skate is built on stilts slightly, but the braking pillar is kiss the earth just, play braking action, therefore the user can be indiscriminately ad. as one wishes to front slide or deceleration or stop, using very convenient and safety, be difficult for falling down.In some workshop, use roller skate of the present invention to make walking-replacing tool, can alleviate workman's physical demands, can increase work efficiency again, simultaneously very safe again.

Embodiment:

Make beam (1) with steel plate, beam length 200mm, wide 30mm, high 10mm has a long 65mm apart from front end 35mm successively along long direction, the kidney slot of wide 6mm, every 15mm, a long 40mm is arranged again, the kidney slot of wide 6mm, the rivet hole that a φ 3mm is arranged every 15mm again has the hole of a φ 6mm then every 14mm.By beam (1) forefoot pedal (2) is connected with rear heel pedal (11), forefoot pedal (2) shape is similar to the half sole (as Fig. 5) of general footwear, the slot that 42 * 7mm are arranged, 2 φ 3mm pin-and-holes, 6 * 6mm square hole is by the square hole of 6 * 6mm and the 65mm kidney slot of beam (1), connect with screw (4), the long 15mm of screw (4), the 5mm of root is the square of 6 * 6mm, remainder is M6mm.Rear heel pedal (1), shape is similar to the heel of general footwear, but upwards bends a wide 15mm endways, and rectangular of high 15mm has the hole of a φ 4mm on it, and it is fixing with pillar square tube (13), back location iron plate (12) to be equipped with screw (15).Have in addition on the rear heel pedal (11) that two φ 3mm holes connect with iron plate (12) riveting of location, back about the hole (as Fig. 7) of the hole of a φ 6mm and 3 φ 3mm, by the φ 3mm hole on center line, with rivet rear heel pedal (11) is connected with beam (1), by its φ 6mm hole, rear heel pedal (11), beam (1) and pillar square tube (13) are coupled together with M6 * 12 screws (14).Pillar square tube (13) as shown in Figure 6, three pairs of φ 4mm holes are arranged on former and later two faces, in the pillar square tube, insert pillar square (16), pillar square (16) is the cuboid vulcanite piece of 65 * 20 * 20mm, the hole that has a φ 5mm to connect at the center of long direction, with the pair of holes of bolt (17) by the pillar square tube, be fixed in the pillar square tube (13), after pillar square (16) wearing and tearing, pillar square (16) can be dropped to second pair of hole, the 3rd pair of hole can be put upside down pillar square (16) then, and pillar square (16) is fully utilized.40mm kidney slot by beam (1) is connected flute profile iron (7) with screw (10) with beam (1), the wide 30mm of flute profile iron (7), the wide 24mm in side, respectively there is the wide 4mm of a correspondence two sides, the kidney slot of long 7mm, the end face of flute profile iron has the square hole (as Fig. 9) of a 6 * 6mm, flute profile iron (7) and rear clamping shaft iron (6) are used, rear clamping shaft iron (6) shape as shown in Figure 8, the wide 41mm that a correspondence is respectively arranged on two sides of U-shaped part, the kidney slot of long 7mm, a through φ 4mm hole is arranged in the junction of annulus, can be by screw axis clamping, under the stressed situation of roller skate, annulus can not open, with flute profile iron (7), rear clamping shaft iron (6) and shock absorbing rubber (8) couple together with bolt (9).Front clamping shaft iron is similar to rear clamping shaft iron (6), couples together with bolt with butterfly iron, shock absorbing rubber.Less because of the force rate that front axle is subjected to, so the screws clamp annulus needn't be arranged, butterfly iron (20) is riveted on the forefoot pedal (2) by 42 * 7mm square boss.Forward and backward folder axle iron is fixedly front axle (5 ') and hind axle (5) respectively, be equipped with the 60mm nylon wheel the roller skate that can brake.Above-mentioned member all uses the 2mm steel plate to make except that back location iron plate (12) is made with the 1mm steel plate.
