V. Description of the invention (10)

In addition, from the ninth figure, it can be found that the conventional implementation mode can keep the platform 11 1 horizontal, unlike the platform 11 in the first embodiment mode, which is the front high & low (see the second figure). It is because the front wheel i5 and the front wheel transmission 22 of the first embodiment are located at the same center point, and the center point of the front wheel 15 is higher than the rear universal wheel 1 2, so that the platform 1 1 forms a front high rear Low form; and the front wheel 15 of the second embodiment is a camouflaged fake wheel, which is eccentric from the front wheel transmission 22, but the small wheel 4 2 hidden inside the front wheel 15 is located at the front wheel transmission 22 The center point of the small wheel 4 2 is lower than the center point of the front wheel 15, but it is level with the center point of the rear universal wheel 丄 2, so the rear end of the platform 1 1 is in a horizontal form. [Third embodiment] As shown in the tenth figure, a rotatable front wheel 15 and a front wheel transmission 22 2 are eccentrically corresponding to each other. The front wheel 15 is a movable runner, and The front wheel 15 of the second embodiment is a false wheel practice for concealment. This is different. The structure of the seven wheel 15 is shown in the tenth figure, which includes a rubber tire 4 that surrounds the outer ring. The ring gear 4 5 provided in the rubber tire, a roller steel ring 4 6 provided in the ring, and a roller steel ring

4 6 has a slot 4 6 2 to accommodate the gear 4 7 in the gear set 3 7. The slot 4 6 2 meshes with the aforementioned ring gear 4 5. In the foregoing, the roller steel ring 46 is fixedly combined with the shaft housing 29, and the ring gear 45 is a branch body of the rubber tire 4 4 'and surrounds the periphery of the roller steel ring 4 6 and has a free rotation function. The outer ring of the roller steel ring 4 6 has a plurality of rollers 4 6 1, so that the ring gear f 5 can produce a rotation effect with a low friction coefficient. The gear 4 7 must pass through the shaft housing 2 9 and the underside of the roller steel ring 4 6

1236444 Missing tooth invention description (11) __________ ”6 2, 2 '3 and rotating with the ring 4 5 5 suit 45 is equal to the front wheel field return wheel 4γ simultaneously driving the front wheel 1 5 is a movable eccentric wheel. When Therefore, in this implementation, when a tricycle 10 is used, it will be found that the rear end of the universal joint 2 observes the movement of the play 1 and rotates freely, while the front two eccentricity 2 will rotate with the platform 1 and this kind of shaft housing The front wheel 5 within 2 9 also rotates the front wheel 15 when stepped on, which is so salty that the bandit 2 2 drives eccentricity. It is also the fourth level of the present invention, which holds the level, like the ninth b. The center point of the front wheel transmission 2 2 is lower than the center point of the front wheel 1 5 is located in the same water. 'This embodiment can make the platform 1 as shown in the figure, because the front wheel 1 is eccentric, that is, The center point of the front wheel transmission 2 2, but on a level line with the rear end universal wheel 1 2. [Fourth consistent sadness example] The meaning is not as shown in the eleventh figure: a rotatable front wheel and the The front wheel transmission 2 2 is in an eccentric corresponding state, but the pedal 2 housing 2 9 is-and the shaft housing 2 9 is provided with an arc-shaped notch 2? After stepping on the pedal 2 3, the axle housing 2 9 will be linked together. The rotation of the axle housing 9 will cause the front wheel 15 to also rotate. This action process can be shown in Figures 13 and 14 ^ The 7-end of the fixed shaft 2 is fixedly connected to the disk body 17 and the other end passes through the gear seat 3 8 (it has been simplified to be fixed to the nut 4 8 behind the disk. This fixed shaft 2 7 is combined with the gear 4 7 and Twist 28 'its towel' gear 47 meshes with the ring gear 50 on the inner wall of the shaft housing 29, and the bottom of the gear 47 passes through the slot 293 of the shaft housing 29 and penetrates

1236444

The missing slot 462θ of the second steel ring 46 is matched with the tooth tg5 in the tire 44 of the front wheel, and a unidirectional shaft is fitted between the gear 47 and the fixed shaft 27, and its end is fixed to the shaft. The narrow shaft 2 p 1 of the case 29 is fixed to the fixed shaft 2 7 at the other end, so when the pedal 2 3 is linked with the shaft case 2 9, it can be restored by the elastic return action of the torsion spring 28 The operator steps on continuously. The transmission process that Shiben only complains is that after stepping on the pedal 23, the shaft casing 29 is rotated and the ring gear 50 in the shaft casing synchronously drives the gear 47, and then the gear 4_7 is transmitted to the teeth of the front wheel X 5 The ring 4 5 enables the tire 4 4 to rotate forward. After the pedaling is completed, the torsion spring 2 8 will return to the shaft housing 2 9 and the pedal 2 3. At this time, the one-way bearing 4 9 fitted in the gear 4 7 forms an idling action, so it will not be transmitted to the front wheel 1 5 The ring gear 4 5 and the pedal 2 3 can be re-pressed by the operator; in this way, continuously pressing the pedal 2 3 continuously will cause the front wheel 丄 5 to rotate forward by intermittent transmission. In addition, no matter how the M wheel 丄 b rotates, its bottom will be confined to the notch 2 9 3 of the shaft housing 2 9. As shown in the figure, the bottom of the roller steel ring 4 6 of the front wheel i 5 is confined to the notch 2 9 3 Inside, so it can regulate the front wheel i 5 will not deflect when turning to avoid problems such as snakes or left and right movement. The biggest feature of this embodiment is that the pedal 23 is integrated with the shaft housing 29, so after stepping on the pedal 23, the two are integrated with each other. This is the same as the shaft housing 29, but only the pedal 23 is in the shaft housing. Swing within the slot 3 is different. Secondly, the transmission of this embodiment is a single gear 4 7 transmission, instead of a speed increasing gear set, it is also feasible if it is converted into a speed increasing gear set.

In addition, a brake assist brake is provided on the brake lever 5 1 of the platform and the end of the brake line is used, so that the above is described in detail according to the drawings; however, various changes are made in the industry, so as long as it does not exceed the scope of the present invention, it is excellent. Operation advancement and progress requirements are based on the [component symbol description] In the implementation mode of one to three, the implementation of the gear wheel of the transmission 14 is also feasible, but when the single gear is implemented, the force applied to the gear set is still small. The most important thing is to use the brakes (up to the safe type shown) can be used wherever the main purpose _. Steering method application for seat 1 line extension does not reveal the good ride effect does not exceed the scope of this issue With the safety patent. 8 The drive to the front wheels on both sides is a habit of the traditional style.
