Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
151 words
A skateboard comprising: an elongated platform having a main body section and a rear tail section angularly movable relative to said main body section; an angularly adjustable joint coupling said tail section to said main body section as a longitudinal extension thereof, said joint having an elongated plate with sufficient strength and stiffness to resist bending under the normal forces exerted on said tail section during use of the skateboard, said plate having front and rear end sections secured to said main body section and said tail section, respectively, and an intermediate section extending between said front and rear end sections, said intermediate section being bendable to a preselected angle to hold said tail section at said preselected angle relative to said body section; and wheel assemblies mounted on the bottom side of said main body section, in longitudinally spaced relation with each other and with the ends of said platform.
Claim 2
Dependent Claim
151 words
A skateboard comprising: an elongated platform having a main body section and a rear tail section angularly movable relative to said main body section; an angularly adjustable joint coupling said tail section to said main body section as a longitudinal extension thereof, said joint having an elongated plate with sufficient strength and stiffness to resist bending under the normal forces exerted on said tail section during use of the skateboard, said plate having front and rear end sections secured to said main body section and said tail section, respectively, and an intermediate section extending between said front and rear end sections, said intermediate section being bendable to a preselected angle to hold said tail section at said preselected angle relative to said body section; and wheel assemblies mounted on the bottom side of said main body section, in longitudinally spaced relation with each other and with the ends of said platform.
Claim 3
Dependent Claim
46 words
A skateboard as defined in claim 1, wherein the front end of said tail section, adjacent to said main body section, includes a forwardly projecting lip, whereby the gap between said platform sections is reduced as said tail section is bent upwardly to a preselected angle.
Claim 4
Dependent Claim
28 words
A skateboard as defined in claim 1 wherein said plate is constructed of aluminum with a thickness of between one-sixteenth of an inch and one-eighth of an inch.
Claim 5
Dependent Claim
140 words
A skateboard comprising: an elongated platform having a main body section and a rear tail section angularly movable relative to said main body section; an angularly adjustable joint coupling said tail section to said main body section as a longitudinal extension thereof, said joint having front and rear hinge elements secured to said main body section and said tail section, respectively, a pin connecting said front and rear hinge elements together to pivot said tail section with respect to said body section, and selectively operable means for locking said hinge elements to prevent relative movement from a preselected angular position, to hold said tail section at said preselected angle relative to said body section; and wheel assemblies mounted on the bottom side of said main body section, in longitudinally spaced relation with each other and the ends of said platform.
Claim 6
Dependent Claim
140 words
A skateboard comprising: an elongated platform having a main body section and a rear tail section angularly movable relative to said main body section; an angularly adjustable joint coupling said tail section to said main body section as a longitudinal extension thereof, said joint having front and rear hinge elements secured to said main body section and said tail section, respectively, a pin connecting said front and rear hinge elements together to pivot said tail section with respect to said body section, and selectively operable means for locking said hinge elements to prevent relative movement from a preselected angular position, to hold said tail section at said preselected angle relative to said body section; and wheel assemblies mounted on the bottom side of said main body section, in longitudinally spaced relation with each other and the ends of said platform.
Claim 7
Dependent Claim
13 words
A skateboard as defined in claim 4, wherein said pin comprises a bolt.
Claim 8
Dependent Claim
34 words
A skateboard as defined in claim 4, wherein said means for locking comprises a bolt threaded to accept a nut, whereby said hinge elements are placed in compressive engagement upon tightening of said nut.
Claim 9
Dependent Claim
25 words
A skateboard as defined in claim 6, wherein said hinge elements have cooperating surfaces with teeth, whereby said teeth interlock upon tightening of said nut.
