Guideway mechanism

Abstract

An exemplary guideway mechanism includes two branches, a plurality of branches each including two parallel rails, a plurality of groups of connecting blocks including four connecting blocks arranged at four corners of an imaginary square, and a plurality of supporting brackets each connecting one corresponding group of connecting blocks. Adjacent ends of the rails of each branch respectively connect two adjacent connecting blocks. Each of two ends of each rail connects one corresponding connecting block. Two adjacent rails respectively located in two adjacent branches are perpendicular to each other and connected together by a respective connecting block of one corresponding group of connecting blocks. The other two rails respectively located in the two adjacent branches connect another two respective connecting blocks of the one corresponding group of connecting blocks. The whole guideway mechanism is in the form of a grid.

What is claimed is: 
     
         1 . A guideway mechanism comprising:
 a plurality of branches each comprising two parallel rails;   
       a plurality of groups of connecting blocks comprising four connecting blocks arranged at four corners of an imaginary square, adjacent ends of the rails of each branch respectively connecting two adjacent connecting blocks, each of two ends of each rail connecting one corresponding connecting block, two adjacent rails respectively located in two adjacent branches being perpendicular to each other and connected together by a respective connecting block of one corresponding group of connecting blocks, the other two rails respectively located in the two adjacent branches connecting another two respective connecting blocks of the one corresponding group of connecting blocks, the whole guideway mechanism being in the form of a grid; and
 a plurality of supporting brackets each connecting one corresponding group of connecting blocks. 
 
     
     
         2 . The guideway mechanism of  claim 1 , further comprising a plurality of locking members, ends of the connecting blocks which do not connect any of the rails connecting instead with corresponding of the locking members, each locking member connecting two respective adjacent connecting blocks. 
     
     
         3 . The guideway mechanism of  claim 2 , wherein two spaced connecting posts protrude from each end of the rail, two spaced connecting holes being defined in each end of each connecting block, the two connecting posts of one end of the rail being inserted into the two connecting holes in a corresponding end of the connecting block to connect the rail with the connecting block together. 
     
     
         4 . The guideway mechanism of  claim 3 , wherein each supporting bracket comprises a rectangular top plate and four supporting poles extending perpendicularly downwardly from four corners of the top plate, each connecting block defining a fixing hole, a bottom end of each supporting pole being inserted into the fixing hole of a corresponding connecting block to connect the supporting bracket with the group of connecting blocks.
