Triple plank platform
A telescoping work platform utilizing three planks that are slidable to each other allows for a longer maximum length for use while providing for a shorter collapsed length for storage all while providing necessary structural support.
1. A telescoping work platform, comprising:
a plank midsection having two longitudinal ends comprising:
an even number of enclosed rectilinear channels extending uninterrupted between the longitudinal ends; and
a reinforcing plate proximate each plank midsection longitudinal end;
two outer plank sections, each outer plank section having two longitudinal ends and comprising:
a number of rectilinear prongs equal to one half the number of rectilinear channels and each rectilinear prong sized to slideably fit within a respective rectilinear channel; and
an end cap at least partially covering one of the outer plank section longitudinal ends;
wherein each rectilinear channel is occupied by a single unique rectilinear prong.
2. The telescoping work platform of claim 1 wherein the outer plank sections are equal in length and the plank midsection is approximately the same length as the outer plank sections.
3. The telescoping work platform of claim 1 further comprising a stop associated with each outer plank section to prevent the complete removal of the two outer plank sections from the plank midsection.
4. The telescoping work platform of claim 1 wherein each reinforcing plate is fastened to the plank midsection by rivets.
5. The telescoping work platform of claim 4 wherein each rectilinear prong has a groove to accommodate a rivet.
6. The telescoping work platform of claim 1 wherein each end cap is fastened to its respective outer plank longitudinal ends by rivets.
7. The telescoping work platform of claim 1 wherein the plank midsection is comprised of extruded aluminum.
8. The telescoping work platform of claim 1 wherein the plank midsection comprises two assemblies, each assembly comprising one or more rectilinear channels.
9. The telescoping work platform of claim 1 wherein each outer plank section prong is a unibody construction.
10. The telescoping work platform of claim 1 wherein each outer plank section prong is comprised of extruded aluminum.
11. A telescoping work platform, comprising:
a plank midsection comprising two longitudinal ends and a number of rectilinear walled channels running uninterrupted between the two longitudinal ends;
two outer plank sections, each outer plank section comprising an end cap and a number of rectilinear prongs equal to no more than one half the number of rectilinear channels, each rectilinear prong sized to slideably fit within a respective rectilinear channel; and
a reinforcing plate proximate each plank midsection longitudinal end;
wherein each rectilinear channel is occupied by a single unique rectilinear prong.
12. The telescoping work platform of claim 11 wherein the telescoping work platform has a collapsed configuration that is approximately one third the length of its fully extended configuration.
13. The telescoping work platform of claim 11 wherein the outer plank sections are equal in length and the plank midsection is approximately the same length as the outer plank sections.
14. The telescoping work platform of claim 11 wherein the plank midsection comprises two assemblies, each assembly comprising one or more rectilinear channels.
15. The telescoping work platform of claim 11 wherein each outer plank section prong is a unibody construction.
16. The telescoping work platform of claim 11 wherein each outer plank section prong is comprised of extruded aluminum.
17. The telescoping work platform of claim 11 further comprising a stop associated with each outer plank section to prevent the complete removal of the two outer plank sections from the plank midsection.
18. The telescoping work platform of claim 11 wherein the plank midsection is comprised of extruded aluminum.
19. The telescoping work platform of claim 11 wherein each end cap is fastened to its respective rectilinear prongs by rivets and each end cap is fastened to its respective longitudinal end of the plank midsection by rivets.
20. A telescoping work platform, comprising:
a plank midsection comprising two longitudinal ends and a number of circumscribed rectilinear channels extending without interruption between the two longitudinal ends; and
two outer plank sections, each outer plank section comprising an end cap and a number of rectilinear prongs equal to less no more than one half the number of rectilinear channels, each rectilinear prong sized to slideably fit within and occupy it own unique respective rectilinear channel.
