Scaffold system and method
View Patent ↗A scaffold system and method having a hollow horizontal member with an internal wedge head at each end thereof, and internal wedge assembly with an external handle, and a vertical member having affixed in coaxial alignment therewith at least one grid patterned rosette. Each internal wedge head at the end of the horizontal member is configured to couple to the grid patterned rosette coupled to the vertical member substantially simultaneously using the wedge assembly mechanism.
1. A scaffold system, comprising:
a horizontal member,
a first vertical member having at least one rosette affixed in coaxial alignment to the first vertical member; and
an internal wedge assembly within the horizontal member, portions of the internal wedge assembly for locking the horizontal member to the at least one rosette,
a first wedge head coupled to a first end of the horizontal member;
a handle;
the internal wedge assembly further comprising a linkage mechanism, the handle being responsively coupled to the linkage mechanism; and
a first rod section, the second end thereof coupled to the linkage mechanism, the first end of the first rod section having a wedge portion for extension and retraction at the first wedge head coupled to the first end of the horizontal member.
2. The scaffold system of claim 1 , further comprising:
a second wedge head coupled to a second end of the horizontal member to be received at a second vertical member having at least one rosette affixed in coaxial alignment to the second vertical member; and;
a second rod section having a wedge portion at the first end thereof for extension and retraction at the second wedge head coupled to the second end of the horizontal member,
wherein the second end of the first rod section and the second end of the second rod section are each rotatably coupled to the linkage mechanism.
3. The scaffold system of claim 2 , wherein the first rod section and second rod section are unequal in length.
4. The scaffold system of claim 2 , the linkage mechanism comprising a crank/cam assembly wherein the second end of the first rod section and the second end of the second rod section are each rotatably coupled to the crank/cam assembly; and
wherein the handle is coupled to the crank/cam assembly, which, when actuated causes the wedge portion of the first rod section and wedge portion of the second rod section to partially or wholly extend or retract through their respective wedge head, and out of the first end and second end, respectively from the horizontal member, depending on the direction that the handle is turned.
5. The scaffold system of claim 4 , wherein the second end of the first rod section and the second end of the second rod section each have an aperture there-through for receiving a coupler forming a rotation joint, each coupler being coupled to the crank/cam assembly.
6. The scaffold system of claim 5 , wherein each wedge head has prongs extending therefrom, the prongs dimensioned to fit within a grid of apertures of the rosette.
7. The scaffold system of claim 6 , further comprising the first and second wedge heads fixedly attached to their respective ends of the horizontal member, each wedge head having a bore therethrough for receiving the wedge portion.
