Description

BACKGROUND OF THE INVENTION
• The present invention relates to a skateboard device. More particularly, the present invention relates to a shock-absorbing skateboard device.[0001]
• A conventional skateboard does not have a handle to direct a direction of movement. The direction of movement is controlled by the feet of the user only. Furthermore, the conventional skateboard cannot absorb shock.[0002]
SUMMARY OF THE INVENTION
• An object of the present invention is to provide a skateboard device which can absorb shock efficiently.[0003]
• Accordingly, a shock-absorbing skateboard device comprises a main board, a downtube connected to the main board, a head tube connected to the downtube, a handle disposed on the head tube, a front wheel connected to the head tube, a rear wheel support frame disposed on a bottom of the main board, and a rear wheel connected to the rear wheel support frame. A shock-absorbing mechanism is connected to the rear wheel support frame. An adjusting mechanism is connected to the shock-absorbing mechanism.[0004]

• FIG. 3 is a partially bottom plan view of a shock-absorbing skateboard device of a preferred embodiment in accordance with the present invention;[0007]
• FIG. 4 is a schematic view illustrating an operation of a shock-absorbing skateboard device of a preferred embodiment in accordance with the present invention;[0008]
• FIG. 4A is a partially enlarged view of an adjusting device of a preferred embodiment in accordance with the present invention; and[0009]
• FIG. 5 is a schematic view illustrating another operation of a shock-absorbing skateboard device of a preferred embodiment in accordance with the present invention,[0010]
DETAILED DESCRIPTION OF THE INVENTION
• Referring to FIGS.[0011]1 to5, a shock-absorbing skate-board device comprises amain board1, adowntube40 connected to themain board1, ahead tube4 connected to thedowntube40, ahandle5 disposed on thehead tube4, afront wheel2 connected to thehead tube4, a rearwheel support frame31 disposed on a bottom of themain board1, and arear wheel3 connected to the rearwheel support frame31.
• A shock-absorbing[0012]mechanism6 is connected to the rearwheel support frame31.
• An adjusting mechanism[0013]7 is connected to the shock-absorbingmechanism6.
• The shock-absorbing[0014]mechanism6 has alink unit62 having afirst link62B and asecond link62A, anelastic element61, and ablocking rod63.
• The[0015]blocking rod63 is disposed on the bottom of themain board1 to block thesecond link62A.
• The[0016]first link62B is connected to the rearwheel support frame31. Thesecond link62A is connected to thefirst link62B and theelastic element61.
• The adjusting mechanism[0017]7 has apositioning seat72 disposed on the bottom of themain board1, aring71 engaging with theelastic element61, and abolt74 fastening thering71 and thepositioning seat72 together.
• A[0018]screw73 fastens thepositioning seat72 and themain board1 together.
• After a long period of usage, the[0019]elastic element61 will be loosened. Thebolt74 is adjusted to tighten theelastic element61.
• Referring to FIG. 5, the[0020]rear wheel3 is bumped by a rough ground. Thesecond link62A will move upward. The shock-absorbingmechanism6 provides a good shock-absorbing effect.
• The invention is not limited to the above embodiment but various modification thereof may be made. Further, various changes in form and detail may be made without departing from the scope of the invention.[0021]
