Claim 4
Dependent Claim
29 words
The collapsible skateboard of claim 2 wherein said connector is a U-shaped member having two upwardly extending lugs each having a surface formed with said first and second recesses.
Claim 5
Dependent Claim
49 words
The collapsible skateboard of claim 3 further comprising a guide member extending over each said surface such that a slot is formed in said connector between said guide member and each said surface and wherein said adjust pin is slidable within said slot between said first and second recesses.
Claim 6
Dependent Claim
45 words
The collapsible skateboard of claim 1 wherein said first end of said spring coupled to said adjust pin is an upper end of said spring, and wherein said spring has a lower end coupled to said connector at a fixed height relative to said platform.
Claim 7
Dependent Claim
214 words
A collapsible skateboard comprising: a platform having a front end; an upright member having upper and lower ends and extending downwardly toward said platform, said upright member having a grip portion at said upper end; a connector mounted on said front end of said platform, said connector formed with a surface having a first recess at a lower end and a second recess at an upper end; a pivot pin coupled to said connector and extending through at least one circular hole in said upright member for pivotally coupling said upright member to said connector; an adjust pin engaging said surface of said connector, said adjust pin being sidable along said surface and insertable into said first and second recesses for locking said upright member in collapsed and operable positions, respectively, relative to said platform; a spring having an upper end coupled to said adjust pin and a lower end coupled to said pivot pin for providing a spring force to maintain said adjust pin in said first or second recess; and a control mechanism coupled to said adjust pin for overcoming said spring force, said control mechanism being adapted to move said adjust pin independently of said upright member and said connector to release said adjust pin from said first or second recess.
Claim 8
Dependent Claim
