Modular in-line skate frame assembly

Abstract

An in-line skate frame includes two lateral plates connected to a mounting plate, and a plurality of longitudinally spaced apart holes disposed transversely in a bottom side of the mounting plate. Each lateral plate includes longitudinally spaced-apart upward projections each having an upper slot, and indented edges each formed between two adjacent upward projections. Each indented edge is spaced apart from the mounting plate to define an aperture with the mounting plate and two adjacent upward projections. Fastening units extend through respective holes and respective upper slots to fasten the lateral plates to the mounting plate. Rollers are fastened to each lateral plate at points below the apertures in each lateral plate, respectively.

1 . An in-line skate frame assembly comprising: 
 a longitudinal mounting plate having top and bottom sides, and a plurality of longitudinally spaced apart holes disposed transversely in said bottom side and opening at two transversely opposed sides of said mounting plate;    two longitudinal lateral plates disposed respectively at said opposed sides of said mounting plate, each of said lateral plates including a plurality of longitudinally spaced-apart upward projections, upper slots formed respectively in said upward projections and aligned with said holes, respectively, and indented edges each formed between two adjacent ones of said upward projections, each of said indented edges being spaced apart from said mounting plate to define an aperture with said mounting plate and two adjacent ones of said upward projections, said aperture being elongated in a longitudinal direction;    a plurality of fastening units each extending through one of said holes and one of said upper slots in each of said lateral plates; and    a plurality of rollers fastened to each of said lateral plates at points immediately below respective said apertures in each of said lateral plates.    
   
   
       2 . The in-line skate frame assembly as claimed in  claim 1 , wherein said mounting plate has a plurality of longitudinally spaced part tubular members that are formed transversely on said bottom side of said mounting plate, each of said tubular members defining said hole and having two transversely opposed open ends.  
   
   
       3 . The in-line skate frame assembly as claimed in  claim 1 , wherein each of said lateral plates further has a bottom edge, and a plurality of longitudinally spaced apart downward projections protruding downward from said bottom edge below said apertures, respectively, said rollers being fastened to said downward projections, respectively.  
   
   
       4 . The in-line skate frame assembly as claimed in  claim 3 , wherein each of said downward projections has a lower slot formed therein.  
   
   
       5 . The in-line skate frame assembly as claimed in  claim 4 , wherein each of said indented edges is concaved downward from two adjacent ones of said upward projections, said bottom edge having a profile that extends upward and downward substantially along said indented edges.  
   
   
       6 . The in-line skate frame assembly as claimed in  claim 4 , wherein said indented edges are substantially straight between two adjacent ones of said upward projections, said bottom edge being substantially straight.  
   
   
       7 . The in-line skate frame assembly as claimed in  claim 1 , wherein each of said fastening units includes a headed tube formed with a female screw therein and extending into one of said holes through one of said upper slots in one of said lateral plates, and a headed male screw extending into said headed tube through one of said upper slots in the other one of said lateral plates and engaging said female screw.  
   
   
       8 . The in-line skate frame assembly as claimed in  claim 1 , wherein each of said fastening units includes a pair of cups fitted tightly in one of said holes of said mounting plate, and a fastener, each of said cups having a cup wall, and a base connected transversely to said cup wall, said bases of said cups being proximate to each other inside said one of said holes, said fastener extending through and fastening said bases of said cups.  
   
   
       9 . The in-line skate frame assembly as claimed in  claim 8 , wherein each of said cups further has a flanged open end, said flanged open ends of said cups respectively abutting against two of said upward projections of said lateral plates, which are aligned with said one of said holes.  
   
   
       10 . The in-line skate frame assembly as claimed in  claim 9 , wherein said fastener is a bolt, each of said fastening units further includes a disc spring disposed around said bolt adjacent to said base of one of said cups.  
   
   
       11 . The in-line skate frame assembly as claimed in  claim 9 , wherein said fastener is a headed pin, each of said fastening units further includes a disc spring, and a C-ring disposed around said headed pin, said disc spring and said C-ring abutting against said bases of said cups, respectively.  
   
   
       12 . The in-line skate frame assembly as claimed in  claim 1 , wherein said mounting plate further includes a toe section, three front binding slots disposed in said toe section, a heel section, and three rear binding slots disposed in said heel section.  
   
   
       13 . The in-line skate frame assembly as claimed in  claim 12 , wherein said front and rear binding slots provide a 165 mm binding distance and a 195 mm binding distance, whereby shoes of different types can be attached to said mounting plate.
