Field of the Invention
This invention is related to an improvement in the structure of a collapsible skateboard.
Description of the Related Art
The conventional skateboard with an upright handle is fixed in structure so that it is difficult to carry. Hence, a collapsible skateboard has been developed to obviate this drawback. However, such a collapsible skateboard is complicated in structure and expensive in cost. Furthermore, the handle of the collapsible skateboard cannot be kept at a fixed position, thereby making it inconvenient to use.
Therefore, it is an object of the present invention to provide an improved collapsible skateboard which can obviate and mitigate the above-mentioned drawbacks.
This invention is related to an improvement in the structure of a collapsible skateboard.
It is the primary object of the present invention to provide a collapsible skateboard that includes an upright handle having lower portion on which is fixedly mounted a bracket, a connector having a curved slot having a lower end formed with a horizontal recess, an upper end formed with a vertical recess, and a circular hole under the vertical recess, an adjust pin inserted into the vertical recess of the connector and the elongated hole of the bracket, a pivot pin fitted through the circular hole of the connector and the circular hole of the bracket, a spring having an upper end connected to the adjust pin and a lower end to the pivot pin, and a platform on which is fixedly mounted the connector.
It is another object of the present invention to provide a collapsible skateboard wherein the connection is a U-shaped member having two upwardly extending lugs each formed with the curved slot.
It is still another object of the present invention to provide a collapsible skateboard further comprising a control mechanism which includes a cylindrical member pivotally mounted on the bracket and having an end extending out of the bracket to fixedly connect with a lever and a hook extending downwardly within the bracket to engage with the adjust pin.
It is still another object of the present invention to provide a collapsible skateboard which can be easily folded as desired.
It is a further object of the present invention to provide a collapsible skateboard which is simple in construction.
Referring to
When desired to fold the skateboard, it is only necessary to move the adjust pin 7 upwardly out of the vertical recesses 321 and then move the handle 4 together with the bracket 5 toward the platform 2 so that the adjust pin 7 is moved along the curved slots 31 to engage with the horizontal recesses 32 (see
Other objects of the invention will in part be obvious and in part hereinafter pointed out.
The invention accordingly consists of features of constructions and method, combination of elements, arrangement of parts and steps of the method which will be exemplified in the constructions and method hereinafter disclosed, the scope of the application of which will be indicated in the claims following.
