Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 445 words
A foldable table leg for use in combination with a table top, the combination having a table surface including a top surface and a bottom surface, at least one foldable leg, said foldable leg includes a leg connecting template fixed to the table surface bottom, said leg connecting template for pivotally securing said foldable table leg to said table, a column base support means attached to said leg connecting template, said column base support means for pivotally receiving said foldable leg recriprocally between a folded position and a supporting position, a track provided intermediate to said leg connecting template, said track for positioning said foldable leg between said folded position and said supporting position, an arm support pivotally secured at one end to said table leg and slidably engaged at another end to said track, said arm support for guiding said leg from said folded position to said supporting position, means for locking said table leg in said supporting position, said locking means attaching to said track, a pivotally mounted release mechanism for releasing said table leg from said supporting position and into said folded position, said folded position for said table leg comprising said folding table leg lying flat against said table bottom surface, said supporting position comprising said folding table leg extending perpendicularly from said table bottom surface, said track having a designed slot provided therein, said arm support including a cross member, said cross member arranged within said designed slot of said track, whereby said foldable leg being pivotal from a supporting position to a folded position, and said cross member shifts within said track slot to provide for retention of said leg at either of its adjusted positions, a spring means operatively associated within said track, said spring means cooperating with said cross member of the arm support to fix said table leg at its erected position with the cross member of the arm support being located at one end of said track slot, and said spring capable of being biased into a condition for releasing said cross member and allowing said table leg to be pivoted into its folded position, said release mechanism cooperating with said cross member and spring means to provide for releasing table leg from its supporting position for shifting into its said folded position, said spring biasing said cross member into direct contact with said release mechanism when said table leg is at its erected position with the cross member of the arm support being located at one end of the said track slot, and with said spring means biasing said cross member contiguously against the release mechanism when the table is in its erected position.
Claim 2
Dependent Claim 445 words
A foldable table leg for use in combination with a table top, the combination having a table surface including a top surface and a bottom surface, at least one foldable leg, said foldable leg includes a leg connecting template fixed to the table surface bottom, said leg connecting template for pivotally securing said foldable table leg to said table, a column base support means attached to said leg connecting template, said column base support means for pivotally receiving said foldable leg recriprocally between a folded position and a supporting position, a track provided intermediate to said leg connecting template, said track for positioning said foldable leg between said folded position and said supporting position, an arm support pivotally secured at one end to said table leg and slidably engaged at another end to said track, said arm support for guiding said leg from said folded position to said supporting position, means for locking said table leg in said supporting position, said locking means attaching to said track, a pivotally mounted release mechanism for releasing said table leg from said supporting position and into said folded position, said folded position for said table leg comprising said folding table leg lying flat against said table bottom surface, said supporting position comprising said folding table leg extending perpendicularly from said table bottom surface, said track having a designed slot provided therein, said arm support including a cross member, said cross member arranged within said designed slot of said track, whereby said foldable leg being pivotal from a supporting position to a folded position, and said cross member shifts within said track slot to provide for retention of said leg at either of its adjusted positions, a spring means operatively associated within said track, said spring means cooperating with said cross member of the arm support to fix said table leg at its erected position with the cross member of the arm support being located at one end of said track slot, and said spring capable of being biased into a condition for releasing said cross member and allowing said table leg to be pivoted into its folded position, said release mechanism cooperating with said cross member and spring means to provide for releasing table leg from its supporting position for shifting into its said folded position, said spring biasing said cross member into direct contact with said release mechanism when said table leg is at its erected position with the cross member of the arm support being located at one end of the said track slot, and with said spring means biasing said cross member contiguously against the release mechanism when the table is in its erected position.
Claim 3
Dependent Claim 71 words
The foldable table leg of claim 1 wherein said release mechanism incorporating a pivotally connected arm and lever, whereby upon actuation of said release mechanism, through pivot of its arm, thereby disposing the lever for biasing contiguously against the cross member to urge against the spring to provide for release of the cross member for shifting along the track slot and allowing the table leg for pivot into its folded position.
Claim 4
Dependent Claim 23 words
The foldable table leg of claim 1 wherein said table leg being formed of light-weight material, and said light-weight material being steel tubing.
Claim 5
Dependent Claim 29 words
The foldable table leg of claim 2 wherein said column base support means includes at least one bumper for protecting said table leg in its folded position during storage.
Claim 6
Dependent Claim 13 words
The foldable table leg of claim 2 wherein said leg includes a foot.
