Safety rail for scaffolding
View Patent ↗A first embodiment of a safety rail for a folding scaffolding cart comprises a single hollow metal tube having two longitudinal ends and shaped to have three smooth 90 degree bends to fit diagonal posts of a folding scaffold. The portable scaffolding cart is a folding platform supported by a rectangular framework having four vertical tube supports with one support tube at each corner. Each support tube has lockable wheels. The vertical supports extend above the platform. The safety rail of the platform connects in an overlapping arrangement to the supports. Alternatively, self-tapping screw fasteners can secure the safety rail. The safety rail is a single shaped tube. Three smooth 90 degree bends in the safety rail allow it to extend upward from a first support, around the perimeter of the platform and back down to a diagonal second support. The safety rail is circular in cross-section, and has a slightly larger diameter than the diameter of the scaffold posts such that each longitudinal end is slotted and sleeved over the first and second diagonal scaffold supports and optionally secured by fasteners. A second embodiment of a safety rail is U-shaped to fit the rear posts of the folding scaffold cart.
1. A safety rail and a portable folding scaffolding cart, comprising:
a portable folding scaffolding cart having vertical front and rear portions of equal length, vertical right and left width portions of equal length, two removable rectangular horizontal foot platforms extending from the right width portion to the left width portion, four cylindrical posts at each corner extending the same height, and wheels on each post; and
a hollow cylindrical tube configured to extend vertically from and overlap one front corner post, continue with a smooth curve horizontally along a front edge of the scaffolding cart to the opposite corner, have an elongated substantially angled configuration to continue to the adjacent rear corner post, and form a smooth curve vertically down to overlap the proximate rear corner post;
whereby a safety rail is provided traversing two sides of the scaffolding cart to ensure protection for the worker from falling off the scaffolding cart.
2. The safety rail according to claim 1 , including a fastening means to adjust its height and to secure vertical ends of the hollow cylindrical tube having slots, to the corner posts.
3. The safety rail according to claim 1 , wherein the fastening means is a self-tapping screw.
4. The safety rail according to claim 1 , wherein the fastening means is a threaded bolt and nut.
5. The safety rail according to claim 1 , wherein the wheels are caster wheels with locking means.
6. The safety rail according to claim 1 , wherein the safety rail is coated with an abrasive layer.
7. The safety rail according to claim 1 , wherein the ends of the safety rail are slotted for attachment to the posts.
8. The safety rail according to claim 1 , wherein the safety rail is made of a metal selected from the group consisting of aluminum, copper and steel.
9. The safety rail according to claim 8 , wherein the safety rail is aluminum.
10. The safety rail according to claim 8 , wherein the safety rail is copper.
11. The safety rail according to claim 8 , wherein the safety rail is steel.
12. A safety rail and a portable folding scaffolding cart, comprising:
a portable folding scaffolding cart having vertical front and rear portions of equal length, vertical right and left width portions of equal length, two removable rectangular horizontal foot platforms extending from the right width portion to the left width portion, four cylindrical posts at each corner extending the same height, and wheels on each post; and
a hollow cylindrical U-shaped tube configured to extend vertically from and overlap one rear corner post, continue with a smooth curve horizontally to a front corner of the scaffolding cart, continue with a smooth curve to the opposite front corner, continue with a smooth curve to the adjacent rear corner post, and form a smooth curve vertically down to overlap the proximate rear corner post;
whereby a safety rail is provided traversing three sides of the scaffolding cart to ensure protection for the worker from falling off the scaffolding cart.
13. The safety rail according to claim 12 , including a fastening means to adjust its height and to secure vertical ends of the hollow cylindrical tube having slots, to the corner posts.
