Abstract

A folding table is comprised of a platform connected by hinges to mounting brackets that partially wrap around the vertical supports of a handrail. Slits extend down from the upper edges of the brackets to mate with slits extending up from the lower edges of locking plates on an opposite side of the vertical supports. One of the mounting bracket is a vertically elongated bracket. A folding diagonal brace comprised of upper and lower braces is connected between a lower side of the platform and the elongated bracket. A lower pin at the lower end of the upper brace is positioned through a longitudinal slot in the lower brace. An upper pin on the upper brace is positioned in a coiled slot at an upper end of the lower brace when the platform is fully raised and the diagonal brace is straightened.

Claims

1. A folding table, comprising:

a platform;

C-shaped mounting brackets hinged to a proximal edge of the platform for partially wrapping around vertical supports of a handrail, wherein the mounting brackets each include slits extending down from upper edges thereof, wherein one of the mounting brackets comprises a vertically elongated bracket;

locking plates for positioning on an opposite side of the vertical supports, wherein the locking plates each include slits extending up from lower edges thereof, and the slits on the locking plates are respectively interlocked with the slits on the mounting brackets when the locking plates are respectively connected to the mounting brackets; and

a folding diagonal brace connected between a lower side of the platform and the elongated bracket.

2. A folding table, comprising:

a platform;

a mounting bracket hinged to a proximal edge of the platform for attaching to a vertical support of a handrail; and

a folding diagonal brace connected between a lower side of the platform and the mounting bracket, wherein the diagonal brace comprises;

an upper brace hinged to the platform;

a lower brace hinged to the mounting bracket;

wherein

the upper brace comprises a pair of bars with upper portions diverged away from each other, and parallel lower portions positioned against opposite sides of the lower brace;

a lower pin connected between the parallel lower portions of the bars;

a longitudinal slot in the lower brace, wherein the lower pin is positioned in the longitudinal slot;

an upper pin connected between the parallel lower portions of the bars;

a coiled slot at an upper end of the lower brace, wherein the upper pin is positioned in the coiled slot when the platform is fully raised and the diagonal brace is straightened.

3. The folding table of claim 2, further including an opening in the longitudinal slot to enable the lower pin to slide in.

4. The folding table of claim 2, further including a notch along a lower edge of the lower brace to provide clearance for the upper pin when the diagonal brace is folded.

5. A folding table, comprising:

a platform;

C-shaped mounting brackets hinged to a proximal edge of the platform for partially wrapping around vertical supports of a handrail, wherein the mounting brackets each include slits extending down from upper edges thereof, wherein one of the mounting brackets comprises a vertically elongated bracket;

locking plates for positioning on an opposite side of the vertical supports, wherein the locking plates each include slits extending up from lower edges thereof, and the slits on the locking plates are respectively interlocked with the slits on the mounting brackets when the locking plates are respectively connected to the mounting brackets; and

a folding diagonal brace connected between a lower side of the platform and the elongated bracket, wherein the diagonal brace comprises;

an upper brace hinged to the platform;

a lower brace hinged to the elongated bracket;

wherein

the upper brace comprises a pair of bars with upper portions diverged away from each other, and parallel lower portions positioned against opposite sides of the lower brace;

a lower pin connected between the parallel lower portions of the bars;

a longitudinal slot in the lower brace, wherein the lower pin is positioned in the longitudinal slot;

an opening in the longitudinal slot to enable the lower pin to slide in;

an upper pin connected between the parallel lower portions of the bars;

a coiled slot at an upper end of the lower brace, wherein the upper pin is positioned in the coiled slot when the platform is fully raised and the diagonal brace is straightened; and

a notch along a lower edge of the lower brace to provide clearance for the upper pin when the diagonal brace is folded.
