Modular halfpipe skateboard ramp and method of constructing

Claim 2

A portable halfpipe for use by skaters, the halfpipe comprising: a left arcuate module including a first support structure and a first arcuate track assembly having a first smooth skating portion thereon; a right arcuate module including a second support structure and a second arcuate track assembly having a second smooth skating portion thereon; and a releasable securing device having a hook member and a receiving member, the hook member engaging the receiving member to assist in clampingly securing the halfpipe together to form a smooth skating surface.

Claim 3

The portable halfpipe of claim 1 wherein: the releasable securing device is a rotolock.

Claim 4

The portable halfpipe of claim 1 further comprising: a planar module disposed between the left and right arcuate modules, the planar module including a support structure and a track assembly having a smooth planar skating portion, the skating portions of the left, right and planar modules cooperating to form a smooth skating surface aligned in a longitudinal plane.

Claim 5

The portable halfpipe of claim 3 comprising: a plurality of right half arcuate modules, a plurality of left half arcuate modules, and a plurality of planar modules; wherein respective left half modules, right half modules and planar modules are arranged along respective laterally extending columns and longitudinally extending rows, each row including a right half arcuate module, a left half arcuate module and a planar module disposed therebetween.

Claim 6

The portable halfpipe of claim 1 wherein: skating portions are permanently affixed to the support structure.

Claim 7

The portable halfpipe of claim 5 wherein: the skating portions are screwed to the support structures.

Claim 8

The portable halfpipe of claim 3 wherein: the releasable securing device is a rotolock.

Claim 9

The portable halfpipe of claim 7 wherein: the planar portion has four male portions and four female portions; at least one of the arcuate modules have a rotatable hook member thereon and the other of the arcuate modules having a receiving member; wherein the hook member and receiving member are cooperable engaged pulling the first and second skating surfaces into engagement with one another.

Claim 10

A portable halfpipe for skating exhibitions comprising: a plurality of modules which are releasable connectable together in a matrix configuration of n×m in size, wherein n corresponds to at least two longitudinally extending rows and m corresponds at least two laterally extending columns of modules to produce an arcuate skating surface; the plurality of modules including at least a pair of left half segments aligned laterally in columns and in abutting relationship with one another and at least a pair of right half segments aligned laterally in columns and in abutting relationship with one another, the at least a pair of left half modules disposed longitudinally with respect to the at least a pair of right half modules to form the plurality of rows; each of the at least a pair of left and right half modules having an arcuate surface and a supporting structure therebeneath supporting the respective arcuate surface; releasable connections to connect the rows and columns of modules together, the connections including at least one hook member and one receiving member which cooperate to clamp modules together; wherein when the plurality of modules are connected together in the matrix configuration, the modules form a smooth skating surface.

Claim 11

A portable halfpipe for skating exhibitions comprising: a plurality of modules which are releasable connectable together in a matrix configuration of n×m in size, wherein n corresponds to at least two longitudinally extending rows and m corresponds at least two laterally extending columns of modules to produce an arcuate skating surface; the plurality of modules including at least a pair of left half segments aligned laterally in columns and in abutting relationship with one another and at least a pair of right half segments aligned laterally in columns and in abutting relationship with one another, the at least a pair of left half modules disposed longitudinally with respect to the at least a pair of right half modules to form the plurality of rows; each of the at least a pair of left and right half modules having an arcuate surface and a supporting structure therebeneath supporting the respective arcuate surface; releasable connections to connect the rows and columns of modules together, the connections including at least one hook member and one receiving member which cooperate to clamp modules together; wherein when the plurality of modules are connected together in the matrix configuration, the modules form a smooth skating surface.

Claim 12

The portable halfpipe of claim 9 wherein: the modules are connectable together forming a 4×3 matrix having four rows and three columns, each row having a left arcuate module, a planar module, and right module.

Claim 13

The portable halfpipe of claim 9 wherein: at least one row of modules includes a generally planar surface which is disposed between the left and right half arcuate modules.

Claim 14

The skating ramp of claim 9 wherein: the connecting means includes a rotolock.

Claim 17

The method of claim 13 further comprising: providing a planar module; and positioning the planar module between the left and right half modules; and connecting the arcuate modules to the planar module to form the smooth continuous skating surface.

Claim 18

The method of claim 13 wherein: rotolocks are used as the locking mechanisms to connect the modules together.
