Foldable leg frame arrangement of foldable table

Abstract

A foldable leg frame arrangement of a foldable table includes two runners extended along two longitudinal sides of a tabletop, a leg frame including a leg folding member, and a reinforcement unit. Each runner has a fastening hole formed at an inner side thereof. The leg folding member has two end portions rotatably inserted into the fastening holes of the runners respectively. The reinforcement unit includes two reinforcing shafts transversely extended from the runners respectively, wherein when the end portions of said leg folding member are rotatably inserted into the fastening holes of the runners respectively, the reinforcing shafts are inserted into the end portions of the leg folding member respectively. Therefor, the reinforcement unit not only forms a double lock configuration to securely mount the leg frame between the runners but also guides the leg frame to be rotated between a folded position and an unfolded position.

         8 . The foldable leg frame arrangement, as recited in  claim 6 , wherein said reinforcing shaft is integrally extended from said outer wall of said runner. 
     
     
         9 . The foldable leg frame arrangement, as recited in  claim 3 , wherein said reinforcing shaft is penetrated through said outer wall of said runner to insert into said end portion of said leg folding member. 
     
     
         10 . The foldable leg frame arrangement, as recited in  claim 4 , wherein said reinforcing shaft is penetrated through said outer wall of said runner to insert into said end portion of said leg folding member. 
     
     
         11 . The foldable leg frame arrangement, as recited in  claim 9 , wherein each of said runners further has a guiding hole formed at said outer wall thereof to coaxially align with said fastening hole, such that said reinforcing shaft passes through said guiding hole of said runner to insert into said end portion of said leg folding member. 
     
     
         12 . The foldable leg frame arrangement, as recited in  claim 10 , wherein each of said runners further has a guiding hole formed at said outer wall thereof to coaxially align with said fastening hole, such that said reinforcing shaft passes through said guiding hole of said runner to insert into said end portion of said leg folding member. 
     
     
         13 . The foldable leg frame arrangement, as recited in  claim 11 , wherein each of said reinforcing shafts has an enlarged shaft head and an elongated elastic shaft body extended therefrom, such that said elastic shaft body is slidably passed through said guiding hole to insert into said end portion of said leg folding member until said shaft head is biased against said outer wall of said runner. 
     
     
         14 . The foldable leg frame arrangement, as recited in  claim 12 , wherein each of said reinforcing shafts has an enlarged shaft head and an elongated elastic shaft body extended therefrom, such that said elastic shaft body is slidably passed through said guiding hole to insert into said end portion of said leg folding member until said shaft head is biased against said outer wall of said runner. 
     
     
         15 . A foldable table, comprising:
 an injection mold tabletop;   two runners coupled at two longitudinal sides of the tabletop, wherein each of said runners has a fastening hole formed at an inner side thereof;   a leg frame which comprises a leg folding member having two end portions rotatably inserted into said fastening holes of said runners respectively to move between a folded position and an unfolded position; and   a reinforcement unit which comprises two reinforcing shafts transversely extended from said runners respectively, wherein said end portions of said leg folding member are rotatably inserted into said fastening holes of said runners respectively and said reinforcing shafts are inserted into said end portions of said leg folding member respectively, so as to securely mount said leg frame between said runners while guiding said leg frame to be rotated between said folded position and said unfolded position.   
     
     
         16 . The foldable table, as recited in  claim 15 , wherein each of said runners comprises an inner wall and an outer wall spacedly apart from each other, wherein said fastening hole is formed at said inner wall of said runner and said reinforcing shaft is coaxially extended through said fastening hole of said runner.
