Sports shoe with angle-adjustable traction members

Abstract

A sports shoe includes a shoe body and a plurality of traction members. The shoe body has a sole portion and mounting seats protruding downwardly therefrom and each defining a chamber. Each traction member includes: a positioning unit mounted in the respective chamber and formed with a threaded hole; a connecting plate movably disposed in the respective chamber under the positioning unit and formed with an oval hole; a cleat disposed in the respective chamber and pivoted to the positioning unit and the connecting plate, and extending outwardly of the respective chamber, an angle of the cleat being adjusted when the connecting plate is moved relative to the positioning unit; a fastener engaging the threaded hole in the positioning unit and abutting against the connecting plate; and a locking unit for preventing relative movement between the positioning unit and the connecting plate when the fastener is tightened.

1 . A sports shoe, comprising:
 a shoe body having a sole portion with a bottom face, and a plurality of mounting seats protruding downwardly from said bottom face of said sole portion, each of said mounting seats having a peripheral wall and a bottom wall that cooperate to define a chamber; and   a plurality of traction members each including
 a positioning unit mounted in said chamber of a respective one of said mounting seats, said positioning unit being formed with a threaded hole centered about a vertical line, and having a bottom surface, 
 a connecting plate disposed in said chamber of the respective one of said mounting seats under said positioning unit and movable relative to said positioning unit along a first direction perpendicular to the vertical line, said connecting plate having an upper surface facing said bottom surface of said positioning unit and a lower surface opposite to said upper surface, said connecting plate being formed with an oval hole through said upper and lower surfaces, said oval hole having a length along the first direction, 
 a cleat having a pivot connection part disposed in said chamber of the respective one of said mounting seats and pivoted to said positioning unit and said connecting plate, and a ground contacting part extending downwardly from said pivot connection part and outwardly of said chamber through said bottom wall of the respective one of said mounting seats, an angle of said cleat relative to a plane parallel to the vertical line being adjusted when said connecting plate is moved relative to said positioning unit along the first direction, 
 a fastener passing through said bottom wall of the respective one of said mounting seats and said oval hole in said connecting plate, engaging said threaded hole in said positioning unit, and abutting tightly against said lower surface of said connecting plate, and 
 a first locking unit provided on said bottom surface of said positioning unit and said upper surface of said connecting plate for preventing movement of said connecting plate relative to said positioning unit along the first direction when said fastener is tightened. 
   
   
   
       2 . The sports shoe of  claim 1 , wherein said positioning unit includes:
 a fixed plate secured fixedly to said sole portion, formed with said threaded hole, and having top and bottom faces;   a grip plate disposed under said fixed plate, connected pivotally to said pivot connection part of said cleat, and having said bottom surface and a top surface opposite to said bottom surface; and   a second locking unit provided on said bottom face of said fixed plate and said top surface of said grip plate for preventing rotational movement of said grip plate relative to said fixed plate and about the vertical line when said fastener is tightened.   
   
   
       3 . The sports shoe of  claim 2 , wherein said grip plate is formed with a through hole through said top and bottom surfaces, said second locking unit including first grip members formed on said bottom face of said fixed plate about said threaded hole, and second grip members formed on said top surface of said grip plate about said through hole, said second grip members engaging said first grip members when said fastener is tightened. 
   
   
       4 . The sports shoe of  claim 3 , wherein said first and second grip members comprise complementary teeth and grooves that extend in radial directions relative to the vertical line. 
   
   
       5 . The sports shoe of  claim 2 , wherein said positioning unit further includes a resilient member interposed between said fixed plate and said grip plate, said resilient member applying a continuous biasing force to said grip plate in a direction away from said fixed plate. 
   
   
       6 . The sports shoe of  claim 2 , wherein said bottom wall of each of said mounting seats is formed with an access hole and a limiting hole, said threaded hole in said positioning unit and at least a portion of said oval hole in said connecting plate being aligned vertically with said access hole,
 said fastener passing through said access hole, said ground contacting part of said cleat passing through said limiting hole.   
   
   
       7 . The sports shoe of  claim 6 , wherein said limiting hole has a width along the first direction that is greater than a thickness of said ground contacting part of said cleat along the first direction. 
   
   
       8 . The sports shoe of  claim 7 , wherein said limiting hole has a length along a second direction perpendicular to the first direction and the vertical line that is greater than a width of said ground contacting part of said cleat along the second direction. 
   
   
       9 . The sports shoe of  claim 1 , wherein said first locking unit includes first catch members disposed on said bottom surface of said positioning unit, and second catch members disposed on said upper surface of said connecting plate and engaging said first catch members when said fastener is tightened. 
   
   
       10 . The sports shoe of  claim 9 , wherein said first and second catch members comprise teeth extending respectively along a second direction perpendicular to the first direction and the vertical line. 
   
   
       11 . The sports shoe of  claim 1 , wherein said positioning unit includes a first coupling part disposed to one side of said threaded hole, said connecting plate includes a second coupling part disposed to one side of said oval hole, and said pivot connection part of said cleat includes a first pivot connection coupled pivotally to said first coupling part and a second pivot connection coupled pivotally to said second coupling part, said second pivot connection being disposed between said first pivot connection and said ground contacting part of said cleat. 
   
   
       12 . The sports shoe of  claim 1 , wherein each of said traction members further includes a resilient member interposed between said positioning unit and said connecting plate, said resilient member applying a continuous biasing force to said connecting plate in a direction away from said positioning unit.
