Description
2361758 VIBRATION DAMPING STRUCTURE FOR ROAD RUNNER The present invention
relates to a vibration damping stnicture'. and more particularly to a vibration damping structure for a road runner.
A conventional road runner in accordance with the prior art has a light weight so that it is convenient for a user to carry the road runner. In addition, the conventional road runner takes little space, thereby saving space.
However, when the conventional road runner is ridden on a rugged road, the frame of the road runner is easily subjected to a severe vibration or shock due to the poor vibration damping effect of the road runner, thereby causing an uncomfortable sensation to the rider. In addition, the rider easily falls down due to the severe vibration, thereby causing a danger to the riderFurther, the conventional road runner only has a front wheel and a rear wheel, and the size of the front wheel and the rear wheel is much smaller than that of the bicycle so that the road runner is not easily controlled by the user, thereby greatly decreasing the rigidity and safety of the road runner, and thereby easily limiting the versatility of the conventional road runner.
The present invention has arisen to mitigate and/or obviate the disadvantac,e of the conventional road runner.
In accordance with the present invention, there is provided a Vibration damping structure for a road runner comprising: a support frame Z71 lt having a front erid; two opposite linking blocks each rotatably mounted on the front end of the support frame; two opposite wheel support brackets each mounted on a respective one of the two linking blocks, two opposite wheels each rotatably mounted on a respective one of the two wheel support brackets-, a T-shaped support block secured on a top side of the front end of the support frame; and two elastic members each biased between the support block and a respective one of the two linking blocks.
The support block includes two sides each defining an elongated slot, and the vibration damping structure further comprises two retaining axles each extending through the elongated slot of a respective one of the two sides of the support block, and through a respective one of the two elastic members for positioning each of the two elastic members.
Each of the two linking blocks defines a screw hole, and each of the two retaining axles each includes a lower threaded end screwed into the screw hole of a respective one of the two linking blocks for securing each of the two retaining axles to the respective linking block.
By such an arrangement, when the two wheels vibrate, each of the two linking blocks are moved by the two wheels to rotate relative to the support frame, thereby biasing each of the two elastic members so as to absorb the vibration of the two wheels, thereby enhancing the vibration damping effect of the vibration damping structure.
In addition, the two wheels are slightly extended outward due to the oscillation of the two link-Ing blocks so as to increase the support width and extent of the two wheels, thereby efficiently enhancing the safety of the road runner during travel.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
2 In the drawings:
Fig. I is an exploded view of a vibration damping structure for a road runner in accordance with the present invention; Fig. 2 is a front plan cross-sectional assembly view of the vibration damping structure as shown in Fig. 1; Fig. is an operational view of the vibration damping structure as shown in Fig. 2-) Fig. 4 is a side plan cross-sectional assembly view of the vibration damping structure as shown in Fig. 1; Fig. 5 is a top plan cross-sectional assembly view of the vibration damping structure as shown in Fig. 1; and Fig. 6 is an operational view of the vibration damping structure as shown in Fig. 5.
Referring to the drawings and initially to Figs. 1-33, a vibration damping I structure for a road runner in accordance with the present invention comprises a support frame 10 having a front end and a rear end, two opposite linking blocks 40 each rotatably mounted on the front end of the support frame 10 in a vertical manner, two opposite wheel support brackets 5 0 each pivotally mounted on a respective one of the two linking blocks 40, two opposite wheels 70 each rotatably mounted on a respective one of the two wheel Support brackets 50, a T-shaped support block 20 secured on a top side of the front end of the support fiame 10, and two elastic members 80 each biased between the support block 20 and a respective one of the two linking blocks 40.
3 The support block 20 includes two sides each defining an elongated slot 21, and the vibration damping structure further comprises two retaining axles 90 each extending through the elongated slot 21 of a respective one of the two sides of the support block 20, and extending through a respective one of the two elastic members 80 for positioning each of the two elastic members 80 between the support block 20 and the respective linking block 40.
Each of the two linking blocks 40 defines a screw hole 41, and each of the two retaining axles 90 has a lower threaded end 91 screwed into the screw hole 41 of a respective one of the two linking blocks 45 for securing each of the two retaining axles 90 to the respective linking block 40.
In operation referring to Figs. 2 and 3 with reference to Fig. 1, when the road runner is ridden on a rugged road, the two wheels 70 will oscillate upward and downward, thereby causing a vibration. When the two wheels 70 vibrate, the two wheel support brackets 50 are also oscillated with the two wheels 70 so that each of the two linking blocks 40 are moved to rotate relative to the support fTame 10, thereby biasing each of the two elastic members 80 as shown in Fig. 33 so as to absorb and damp the vibration of the two wheels 70, thereby greatly enhancing the vibration damping and shock absorbing effect of the vibration damping structure.
In addition, the wheels 70 are slightly extended outward due to the oscillation of the two linking blocks 40 as shown in Fig. 3, so as to increase the support width and extent of the two wheels 70, thereby efficiently enhancing the safety of the road runner during travel.
4 Referring to Figs. 4-6 with reference to Fig. 1, a head tube 100 is pivotally mounted on the rear end of the support frame 10, a pivot plate I 10 is secured on the head tube 100 to pivot therewith, two opposite first linking rods 61 are each pivotally mounted on the pivot plate I 10, two opposite adjusting nuts 65 are each movably mounted on a respective one of the two first linking rods 6 1, two opposite second linking rods 60 are each movably mounted in a respective one of the two adjusting nuts 65 and are each pivotally mounted on a respective one of the two wheel support brackets 50.
The rear end of the support frame 10 defines a pivot hole I I for receiving the head tube 100 therein. A steering rod 120 is secured on the h ad ID e tube 100 to be held by a user for rotating the head tube 100 so as to change the steering direction of the road runner.
Each of the linking blocks 40 is rotatably mounted on the front end of the support frame 10 in a vertical manner, and includes an ear 43 extending outward therefrom and pivotally received in the respective wheel support bracket 50.
Each of the two wheel support brackets 50 is pivotally mounted on the respective linking block 40 in a horizontal manner, and defines a receiving recess 51 for receiving the ear 43 of the respective linking block 40 and the respective second link-Ing rod 60 therein. Each of the wheel support brackets 50 also includes an support axle 52 extending outward therefrom and received in the respective wheel 70.
In such a manner, the wheel support bracket 50, the first linking rod 6 1, the second linking rod 60, and the pivot plate I 10 are adapted to form a four-linkage mechanism so as to achieve the purpose of a directional change of the road runner, thereby facilitating steering the steering rod 120 of the road runner.
By means of the four-linkage mechanism of the steering structure of the present invention, when the user wishes to change the steering direction of the road runner, the steering rod 120 is turned toward the desired direction as shown in Fig. 6 so as to rotate the head tube 100. The pivot plate 110 is then pivoted with the head tube 100 from the position as shown in Fig. 5 to the position as shown in Fig. 6. The first linking rods 61 and the second linking rods 60 are moved with the pivot plate 110 so as to pivot the wheel support bracket 50 relative to the linking block 40 so that the wheels 70 are turned to mate with the desired direction of the steering rod 120 so that the direction of travel of the two wheels 70 is in correspondence to the steering direction of the steering rod 120, thereby achieving the purpose of changing the steering direction of the road runner.
Each of the first linking rods 61 is provided with a first outer thread, and each of the two second linking rods 60 is provided with a second outer thread having a direction of screw different from that of the first Outer thread of the respective first linking rod 61. In such a manner, the adjusting nut 65 can be rotated on the first linking rod 61 and the second linking rod 60 so as to slightly adjust the length of the first linking rod 61 and the second linking rod 60 and to slightly adjust the relative distance between the first linking rod 61 and the In zn second linking rod 60, thereby finely the direction of travel of the two wheels 70.
6 It should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
