Abstract
A multi-use motorcycle apparatus and method therefor capable of being easily transported and configured into any of three different apparatuses usable for motorcycles: (a) a towing trailer for a motorcycle where the trailer is dimensioned to be coupled to a vehicle receiver hitch; (b) a frame lift for lifting and supporting the frame of a motorcycle; and (c) a motorcycle lock.
Claims20
A multi-use motorcycle apparatus comprising, in combination:
- four substantially L-shaped members each comprising a large cross-section member having a first end and a second end and a small cross-section member having a first end and a second end, said first end of said large cross-section member is coupled to said second end of said small cross-section member, said first end of said small cross-section member of each of said four substantially L-shaped members is dimensioned to be coupled to said second end of said large cross-section member of any other said substantially L-shaped member so as to form a four-sided figure when said second end of said small cross-section member of each substantially L-shaped member is coupled to said first end of said large cross-section member of another substantially L-shaped member;
- and
- four coupling mechanisms each comprising a first mating member coupled to said first end of each said small cross-section member of said four substantially L-shaped members and a second mating member coupled to said second end of each said large cross-section member of said four substantially L-shaped members, said first mating member of any one said substantially L-shaped member is dimensioned to mate with said second mating member of any other said substantially L-shaped member to secure said small cross-section member of any one said substantially L-shaped member to said large cross-section member of any other said substantially L-shaped member.
A method for lifting the frame of a motorcycle comprising, in combination, the steps of:
- providing four substantially L-shaped members each comprising a large cross-section member having a first end and a second end and a small cross-section member having a first end and a second end, said first end of said large cross-section member is coupled to said second end of said small cross-section member;
- coupling said first end of said small cross-section member of each of said four substantially L-shaped members to said second end of said large cross-section member of any other said substantially L-shaped member so as to form a four-sided figure when said second end of said small cross-section member of each substantially L-shaped member is coupled to said first end of said large cross-section member of another substantially L-shaped member;
- providing four coupling mechanisms each comprising a first mating member coupled to said first end of each said small cross-section member of said four substantially L-shaped members and a second mating member coupled to said second end of each said large cross-section member of said four substantially L-shaped members;
- mating said first mating member of any one said substantially L-shaped member with said second mating member of any other said substantially L-shaped member to secure said small cross-section member of any one said substantially L-shaped member to said large cross-section member of any other said substantially L-shaped member;
- providing a substantially T-shaped coupler, said coupler comprises a short portion dimensioned to be coupled around one of said four substantially L-shaped members and said coupler comprises a long portion having a female end opposite said short portion;
- coupling said short portion of said coupler around one of said four substantially L-shaped members;
- providing a shaft having four sections of descending cross-sectional size, said four sections are dimensioned to nest one inside of another;
- coupling the largest section of said shaft to said female end of said long portion of said coupler, said remaining sections of descending cross-sectional size extend away from said four substantially L-shaped members;
- positioning said coupler so that said long portion is projecting at a ninety degree angle from the top side of said four-sided figure formed by said L-shaped members;
- placing said four-sided figure under a motorcycle frame with said shaft extending in an upward direction;
- and
- pushing down said shaft until said four-sided figure contacts and then lifts said motorcycle frame above ground.

- coupling said first end of said small cross-section member of each of said four substantially L-shaped members to said second end of said large cross-section member of any other said substantially L-shaped member so as to form a four-sided figure when said second end of said small cross-section member of each substantially L-shaped member is coupled to said first end of said large cross-section member of another substantially L-shaped member;
- providing four coupling mechanisms each comprising a first mating member coupled to said first end of each said small cross-section member of said four substantially L-shaped members and a second mating member coupled to said second end of each said large cross-section member of said four substantially L-shaped members;
- adjusting said four-sided figure with respect to length and width to create a size appropriate to receive a motorcycle tire;
- mating said first mating member of any one said substantially L-shaped member with said second mating member of any other said substantially L-shaped member to secure said small cross-section member of any one said substantially L-shaped member to said large cross-section member of any other said substantially L-shaped member;
- providing a substantially T-shaped coupler, said coupler comprises a short portion dimensioned to be coupled around one of said four substantially L-shaped members and said coupler comprises a long portion having an end opposite said short portion dimensioned to couple to a vehicle receiver hitch;
- coupling said short portion of said coupler around one of said four substantially L-shaped members so that said long portion of said coupler extends outside of said four-sided figure in the same plane as said four-sided figure;
- coupling said long portion of said coupler at said end opposite said short portion to a vehicle receiver hitch;
- providing a shaft having four sections of descending cross-sectional size, said four sections are dimensioned to nest one inside of another when said shaft is retracted;
- coupling at least one interior section of said shaft to said coupler so that both ends of said shaft extend away from said coupler in a horizontal direction;
- providing two substantially L-shaped attachments;
- coupling said two substantially L-shaped attachments to opposite end sections of said shaft;
- providing a first tie and a second tie each having a first end and a second end;
- coupling said first end of said first tie to one of said two substantially L-shaped attachments;
- coupling said first end of said second tie to the other of said two substantially L-shaped attachments;
- coupling said second end of said first tie to a portion of a motorcycle;
- and
- coupling said second end of said second tie to a portion of a motorcycle.
