Foldable joint of a sports goal

Abstract

A foldable joint of a sports goal, especially a foldable joint disposed on a rod body of a goal for soccer, handball, hockey, etc., to facilitate folding for storage and portable transportation; the foldable joint has at least an inner connecting rod, an outer toggle, two pivot bolts and adapters disposed at the distal ends of the rod body; wherein a slot way is disposed in the inner connecting rod for receiving the adapter of the rod body; two ends of the adapter are respectively disposed with the pivot bolts for connection; the outer toggle rotates about the outer periphery of the inner connecting rod to clamp and release thereby controlling the folding for storage and extendable positioning of the connected rod body.

1 . A foldable joint of a sports goal mainly applied to a goal rod body, wherein the foldable joint comprising an inner connecting rod, an outer toggle, two pivot bolts and adapters disposed at distal ends of the rod body is characterized that: 
 the inner connecting rod has a communicated slot way disposed therein and an inner stopper formed in the middle thereof; the two sides of the inner stopper and the two ends of the slot way receive the adapters to connect with the rod body; four convex portions are disposed in the corresponding areas at the front and rear ends on the outer ring surface of the inner connecting rod and correspondingly inserted into four retaining slots on the inner side of the inserted outer toggle;    the outer toggle is a hollow sleeve with a hollow slot formed at the center for receiving the inner connecting rod; wherein the central position of the hollow slot is disposed with an outer stopper corresponding to the inner stopper of the inner connecting rod;    the adapters has through holes disposed at the central positions thereof for the insertion of the pivot bolts and fastening in the slot way of the inner connecting rod;    when the outer toggle rotates around the external periphery of the inner connecting rod, the convex portions of the rod body retain with and position at the retaining slots of the outer toggle correspondingly; the retaining slot previously corresponding to the convex portion rotates to the other corresponding convex portion; as this time, the rotation of the outer toggle makes the outer stopper push against the adapters and the rod body unable to be folded thereby limiting the extension; the inner and outer stoppers control the folding for storage and extendable positioning of the rod body connected in the slot way.    
     
     
         2 . The foldable joint of a sports goal according to  claim 1 , wherein the shapes of the inner stopper of the inner connecting rod and the outer stopper of the outer toggle are the same.  
     
     
         3 . The foldable joint of a sports goal according to  claim 1 , wherein the positions of the inner stopper of the inner connecting rod and the outer stopper of the outer toggle correspond to each other.  
     
     
         4 . The foldable joint of a sports goal according to  claim 1 , wherein the corresponding between the convex portion on the external surface and the retaining slot on the outer toggle makes the outer toggle rotate at 180 degree.  
     
     
         5 . The foldable joint of a sports goal according to  claim 1 , wherein the shape of the adapter end portion has to be of a circular and spherical shape for enabling the connected rod body to rotate.  
     
     
         6 . The foldable joint of a sports goal according to  claim 1 , wherein the rod body connected at the adapter has to use the pivot bolt fixedly disposed at the adapter as an axle center to rotate.
