Starting platform wedge assembly
View Patent ↗An anchor for a rectangular tube employs a wedge assembly, whereby rotation of an adjustment bolt of the wedge assembly moves an upper and lower wedge member together, and the wedge engagement with a central wedge member causes said central wedge member to move toward engagement with the tube, thereby securing the tube within a base body. Clevis pins and corresponding key hole slots mount the wedge assembly to a base, while allowing easy removal of the wedge when desired.
1. An anchor device for a rectangular tube member, comprising:
a base body;
a liner member within said base body, said liner member comprising a polymer defining at least one open face along an extent of the base body;
a wedge assembly secured to said base body along a portion of the open face of said liner member and defining a receiving portion to receive the rectangular tube between said liner member and said wedge assembly; and
an adjustment device for adjustably extending or retracting a portion of said wedge assembly into engagement against the rectangular tube when received in the receiving portion,
further comprising a biasing member within the wedge assembly for urging said wedge assembly away from engagement with the rectangular tube.
2. The anchor device according to claim 1 , wherein said wedge assembly comprises an upper, central and lower wedge member.
3. The anchor device according to claim 2 , wherein said adjustment device comprises an adjustment bolt engaged with said upper and lower wedge members, whereby rotation of said adjustment bolt urges said upper and lower wedge member closer or farther apart, and wherein said upper and lower wedge members and said central wedge member cooperate such that said central wedge member is thereby urged toward or away from engagement with said rectangular tube.
4. The anchor device according to claim 2 , wherein said biasing member urges said upper and lower wedge members away from one another.
5. The anchor device according to claim 1 , wherein said wedge assembly is adapted for easy removal.
6. The anchor device according to claim 1 , wherein said liner member within said base body comprises a polymer that is “C”-shaped when considered in horizontal cross-section.
